93 cause SILC_NOTIFY_TYPE_ERROR notify message to the sender.
94 Updated the protocol specs and the code in server. The
95 affected file is silcd/packet_receive.c.
97 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
99 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
100 that it is used to send error notifys if error occurs during
101 some SILC packet processing, except commands. The error
102 types are same as for command reply types. Defined that
103 if private message is sent to unknown Client ID the error
104 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
105 Updated the protocol specs and code. Affected files are
106 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
107 lib/silcclient/client_notify.c, silcd/packet_receive.c,
108 and irssi/src/silc/core/client_ops.c. Renamed the
109 SilcCommandStatus to SilcStatus.
111 * Defined the use of extra WHOIS attributes in WHOIS command.
112 The <Requested Attributes> (defined in a separate document)
113 can be used to request additional information about user
114 not returned by standard WHOIS command. Defined that server
115 can send WHOIS command directly to client. Client provides
116 the requested attributes to the server. Updated the protocol
117 specs. Protocol TODO #4. Implementation is not done yet
120 * Renamed function silc_client_command_status_message to
121 silc_client_status_message. Affected files are

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

156 and secret channels too. Updated protocol specs and the
157 code in server. Affected file silcd/command.c.
159 * Defined <channel user mode list> argument to WHOIS command
160 reply for returning user modes on the channels. The
161 channel list now doesn't include the user mode anymore but the
162 actual channel mode. Updated protocol specs and the code in
163 client and server. Affected files are silcd/command_reply.c,
164 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,

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

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

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

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

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

316 * Changed the silc_client_close_connection interface to not
317 need the SilcSocketConnection which should not be visible
318 to application. Affected files are lib/silcclient/client.c
319 and lib/silcclient/silcclient.h.
321 * Rewrote the text for Private Message Key Payload in the
322 protocol specification. Protocol TODO #11.
324 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
326 * Upgraded the protocol version to 1.1, updated protocol specs

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

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

373 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
374 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
375 and lib/silcclient/client_ops_example.c.
377 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
378 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
379 the channel. Updated protocol specs and impelemented this
380 to client and server. Protocol TODO #6. Affected files are
381 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

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

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

435 totally saved 16 bytes of memory per context after optimization.
436 Affected files are lib/silccore/silcpacket.[ch].
438 * Made strict checks for valid SILC IDs. Affected file is
439 lib/silccore/silcid.c.
441 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
443 * Changed the object argument for silc_cipher_register,
444 silc_hash_register, silc_hmac_register and silc_pkcs_register
445 to const. Affected files are lib/silccrypt/silccipher.[ch],
446 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
448 * Changed the silc_get_username and silc_get_real_name to
449 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
451 * Fixed the Irssi SILC Client to use the silc_get_username and
452 silc_get_real_name insted of glib routines since the glib
453 routines only corrupt stack. Fixes the Irssi SILC to work in
454 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
456 * Fixed the Irssi to not use g_get_home_dir since it crashes
457 or returns garbage on cygwin and corrupts stack. Added function
458 get_home_dir to Irssi routines. Affected files are
459 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
461 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
463 * Made some structure optimizations. SFTP memory FS MemFSEntry
464 entry structure. Optimized SilcTask structure. Optimized
465 SilcPacketContext structure.
467 Affected files lib/silcsftp/sftp_fs_memory.c,
468 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
470 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
472 * And yet again reverted back the config thing since Johnny
473 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
476 * Fixed memory leaks from config object. Affected files are
477 silcd/serverconfig.[ch].
479 * Added support for adding new connections to the server in rehash.
480 After rehash they take effect.
482 Added support for changing the maximum allowed connections in
483 rehash. The number can grow but going smaller is not supported.
485 Added function silc_server_num_sockets_by_remote to the
486 silcd/server_util.[ch].
488 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
490 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
492 * Added preliminary checking during config parsing for a valid
493 public/private key and removed further checks in the code.
494 Affected files are silcd/serverconfig.[ch], server.c.
496 * Moved functions silc_server_drop() and silc_server_daemonise()
497 from server.c to silcd.c since they are stricly related to
498 the application activity.
500 * Reverted a small part of the automatic ref/unref since
501 it caused a double unref in some situations. Affected
502 files are silcd/silcd.[ch], server.c, serverconfig.c.
504 * Added some .cvsignore files in the lib directory.
506 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
508 * Fixed silc_net_gethostbyaddr to correctly resolve by
509 address. Affected file lib/silcutil/silcnet.c.
511 * Fixed the notify relaying to client. The HMAC to be used
512 with relayed packets ws wrong and caused decryption failure
513 at the client end. Affected file is silcd/packet_receive.c.
515 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
517 * Created new branch silc_protocol_1_0_branch.
519 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
521 * Changed the silc_server_config_* routines to be SilcServer
522 independent. They are now officially application specific code
523 and not part of generic server implementation. Affected files
524 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
526 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
528 * Added automatic referencing of config context in the
529 silc_server_config_alloc, and automatic unreferencing in the
530 silc_server_config_destroy. Affected files are
531 silcd/serverconfig.[ch], silcd/silcd.c.
533 * Fixed the silc_log_quick handling in the logging routines.
534 It didn't log quickly when it was TRUE. Affected file is
535 lib/silcutil/silclog.c. Also the flush delay was set even
536 if it was 0 in config file. Affected file is
537 silcd/serverconfig.c.
539 * Added support for changing key pair of the server in rehash.
540 Affected file silcd/server.c.
542 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
544 * Fixed the TOPIC_SET notify to not cras. It changed the topic
545 too early, before getting the channel entry. Affected file
546 is silcd/packet_receive.c.
548 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
550 * Added functions silc_server_config_[ref/unref], these are used
551 to prevent that the config object is destroyed.
553 No longer directly affect global variables silc_log_quick and
554 silc_log_delay, they are first cached inside the config object
555 and then applied with silc_server_config_setlogfiles().
557 silc_server_config_set_defaults() is now internal to
558 serverconfig.c, there are no reasons to show this internal stuff
561 Affected files are silcd/serverconfig.[ch].
563 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
564 fprintf's to stderr, since some code may be executed again after
565 the server went into the background. Affected files are
568 * Added rehash support. Added function silc_server_rehash() that
569 will perform all the basic tasks of the rehashing procedure.
571 * Added command line option `-x, --hexdump'. This will enable the
572 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
573 The option `--hexdump' implies `--debug'.
575 * Fixed a bad bug in the logging APIs (silcutil library) where
576 the application would crash after calling silc_log_reset_all().
578 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
580 * Fixed the KICKED notify handling in client library to
581 correctly remove the channel and all entries from the
582 channel when I was kicked. This bug crashed the client.
584 Fixed yet another but in KICKED notify handling to remove
585 the kicked client correctly from the channel.
587 Affected file is lib/silcclient/client_notify.c.
589 * Fixed a minor bug in looking up correct client entry
590 in KICKED notify in server. Affected file is
591 silcd/packet_receive.c.
593 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
594 sources correctly to distribution. Fixes --with-gmp option.
596 * Removed the manual rehashing from ID Cache, and changed it
597 to use the SILC Hash Table's auto rehash feature. Affected
598 file is lib/silccore/silcidcache.c.
600 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
602 * Fixed a bug in the silc_client_nickname_format function that
603 handles the multiple same nickname formatting. Two clients
604 with same nickname caused problems after the first one left
605 and rejoined. It didn't format the nickname correctly.
606 Affected file is lib/silcclient/idlist.c.
608 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
610 * Don't change the topic if olod topic is same as new one.
611 Affected file is silcd/packet_receive.c.
613 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
615 * Added cross-reference support to the SILC Documentation
616 generator. All types across all HTML files are now cross-
617 referenced. Affected files util/robodoc/generator.c and
618 scripts/silcdoc/silcdoc.
620 * Added file lib/silcutil/silctypes.h to include all the
621 arithmetic type definitions and some macros. Removed
622 includes/bitmove.h and moved macros to silctypes.h.
624 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
626 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
628 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
630 * Added `type' argument to silc_id_payload_parse_id function which
631 now returns the type of the ID to the sent pointer. Affected
632 file is lib/silccore/silcid.[ch].
634 * Added check for CMODE_CHANGE notify type that mode change is
635 allowed by the sender. Affected file silcd/packet_receive.c.
637 * Added check for CUMODE_CHANGE notify type that mode change is
638 allowed by the sender. Affected file silcd/packet_receive.c.
639 Added the ID type as CUMODE_CHANGE notify type as argument
640 to the `notify' client operation. Affected files are
641 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
643 * Added function silc_client_add_server to the client library.
644 Added support for resolving also channel and server info when
645 received unknown entity in notify packet. Affected files are
646 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
648 * Added function silc_command_get_status to return the command
649 status from the command reply's argument payload. Affected files
650 are lib/silccore/silccommand.[ch].
652 * Added check for KICKED notify type that the kicking is
653 allowed by the client. Affected file silcd/packet_receive.c.
655 * Created function silc_get_input which can be used to get input
656 (echo on or off) from user on command line. Affected files are
657 lib/silcutil/silcutil.[ch].
659 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
661 * Optimized silc_server_packet_relay_to_channel function.
662 Added new function silc_channel_message_payload_encrypt which
663 can be called directly if channel message payload needs to
664 be encrypted and is already encoded (no need to call _encode
665 function). Packet relaying is now done by router without any
666 extra memory allocations. Affected files are
667 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
670 * Fixed the INVITE notify handling. It took wrong arguments
671 as invite list and invite delete. Affected file is
672 silcd/packet_receive.c.
674 * Added check for TOPIC_SET notify type that the topic change is
675 allowed by the client. Affected file silcd/packet_receive.c.
677 * Added check for INVITE notify type that inviting is allowed by
678 the client. Affected file silcd/packet_receive.c.
680 * Changed the silc_server_client_on_channel to return the
681 SilcChannelClientEntry as well. Moved the function
682 silc_server_check_cmode_rights to server_util.[ch].
683 Affected files are silcd/server_util.[ch], silcd/command.c.
685 * Added function silc_server_check_umode_rights to check whether
686 changing client's user mode is allowed. Added check for
687 UMODE_CHANGE notify type that the umode change is allowed
688 by the client. Affected files are silcd/server_util.[ch],
689 silcd/packet_receive.c and silcd/command.c.
691 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
693 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
694 ID length. It ignored that ID can be IPv6 based as well.
695 Affected file lib/silccore/silcpacket.h.
697 * Fixed the silc_id_id2str and silc_id_str2id to take the
698 IPv6 address offset's into consideration. Affecte file is
699 lib/silccore/silcid.c.
701 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
703 * Fixed the internal Unix scheduler functions to check for
704 NULL context they may receive. The affected file is
705 lib/silcutil/unix/silcunixschedule.c.
707 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
709 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
710 can specify different directory with --home command line
711 parameter. Affected files irssi/src/silc/core/client_ops.c,
714 * SILC-specific commands aren't now executed if the active server
715 isn't of SILC-type, so there won't be problems with having
716 IRC and SILC protocol support in same client. Affected files
717 irssi/src/silc/core/silc-channels.c, silc-servers.c,
720 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
722 * Improved the signal support in SILC Schedule. Added new
723 function silc_schedule_signal_call which is used by application
724 to mark a signal to be called. It is now safe to perform
725 any kind of tasks in signal callbacks since it is guaranteed
726 that the application specified signal callback is called
727 after the signal is over. Affected files are
728 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
730 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
732 * Added `name' field to SilcChannelPrivateKey to represent
733 application given name for the key. Moved also the context from
734 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
735 Added the `name' argument also to the function
736 silc_client_add_channel_private_key.
738 Added function silc_client_current_channel_private_key to set the
739 current channel private key in use.
741 Added "change" command to KEY command which can be used to change
742 the current channel private key. Bound the command also to
745 Also affected files lib/silcclient/client_channel.c,
746 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
748 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
750 * Added silc_rng_get_byte_fast function in to the
751 lib/silccrypt/silcrng.[ch].
753 * Changed the interface of silc_packet_assemble and the
754 silc_packet_send_prepare. If silc_packet_assmble is now
755 called the application does not call silc_packet_send_prepare
756 because the library will call it automatically. These
757 interfaces now also return a reference to the outgoing buffer
758 which includes the assembled packet, which the application can
759 use to encrypt the packet.
761 Affected files are lib/silccore/silcpacket.[ch],
762 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
763 silcd/packet_send.c, server_backup.c and packet_receive.c.
765 * Fixed a packet sending bug on very high load, where outgoing
766 packet queue wasn't handled correctly and packets got corrupted.
767 Affected files are lib/silcutil/*/silc*sockconn.c,
768 lib/silcclient/client.c and silcd/server.c.
770 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
772 * Added macro SILC_PACKET_DATALEN which can be used during
773 packet assembling to check whether the data to be added to
774 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
775 len is truncated until it fits it.
777 Added checks for maximum length of channel message payload and
778 private message payload also.
780 Added checks for maximum packet length in server and in
783 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
784 lib/silcclient/client.c, lib/silccore/silcchannel.c and
785 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
786 lib/silcclient/client_prvmsg.c.
788 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
790 * Added silc_server_packet_queue_purge call to the
791 silc_server_disconnect_remote to assure that all data in the
792 queue before disconnecting is sent to the network. Affected
795 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
797 * Added the deleting of server's own ID cache entry to the
798 silc_server_free function. Free also everything else that
799 has been allocated in silc_server_init. The affected file
802 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
804 * Added functions silc_parse_version_string, silc_version_to_num,
805 and silc_ske_parse_version to parse SILC protocol style version
806 strings. Affected files lib/silcutil/silcutil.[ch] and
807 lib/silcske/silcske.[ch].
809 * Added new configuration params: version_protocol, version_software
810 and version_software_vendor to specify what version the remote
811 host must at least be to be able to connect to server. The vendor
812 string can be regex matched too. Added new function
813 silc_server_connection_allowed to check maximum number of allowed
814 connections, and allowed versions for incoming connections.
815 Affected files are silcd/server.c, server_util.[ch] and
818 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
820 * Added preliminary support for signals in scheduler. The
821 signals we care about are now blocked always when the scheduler
822 is locked. This way we can synchronise the use of signal with
823 scheduler. It is guaranteed that when signal occurs the scheduler
824 is not locked, and thus new tasks can be safely added to the
827 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
828 to silc_schedule_internal_init and silc_schedule_internal_uninit.
829 Added new platform specific routines
830 silc_schedule_internal_signals_[un]block and
831 silc_schedule_internal_signal_[un]register.
833 Added new functions to SILC Schedule API:
834 silc_schedule_signal_[un]register. Each signal that application
835 is going to use should be registered to the scheduler.
837 Affected files are lib/silcutil/silcschedule.[ch],
838 lib/silcutil/*/silc*schedule.c.
840 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
842 * Check for unauthenticated client and server in the
843 silc_server_new_client and silc_server_new_server functions.
844 Affected file silcd/packet_receive.c.
846 * Added function silc_string_is_ascii to check whether given
847 string is 7-bit ASCII string. Affected files are
848 lib/silcutil/silcutil.[ch].
850 * Added function silc_id_is_valid_server_id into the
851 silcd/serverid.c and added checking for valid Server ID's in
852 silc_server_new_server. The Server ID must always be based
853 on the server's public IP address.
855 * Added logging of DISCONNECT packet message in the server.
856 Affected file silcd/server.c.
858 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
860 * Changed all library interfaces that use Global RNG to also
861 accept SilcRng as argument. Affected files are
862 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
863 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
864 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
865 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
868 * Added function silc_pkcs_generate_key to the
869 lib/silccrypt/silcpkcs.[ch] for applications so that they
870 don't need to do pkcs->pkcs->init calls anymore.
872 * Remove SilcSocketConnection from the SFTP API since it really
873 wasn't needed there. The application has the information
874 saved in its contexts anyway and the SFTP layer doesn't need
875 know about it. Affected files lib/silcsft/silcsftp.h and
876 lib/silcsftp/sftp_[server/client].c.
878 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
879 The SilcSimContext is not SilcSim.
881 * Fixed possible buffer overflows in silc_id_render in the
882 lib/silcutil/silcutil.c.
884 * On EPOC the global crypto module lists are not used at all
885 in the crypto library. Added support for using the constant
886 algorithm list on EPOC. Affected files are
887 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
890 * Fixed the handling of third parameter of KICKED notify, since
891 it was mistakenly updated to SILC Protocol 1.0 even though it
892 is to be included in 1.1. Since it is not in 1.0 it is not
893 mandatory, and this fix now handles it only if it is provided,
894 and it is not error if it is not provided. Affected file
895 lib/silcclient/client_notify.c.
897 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
899 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
900 client. Affected file irssi/src/silc/core/client_ops.c.
902 * Merged with Irssi 0.8.4 from irssi.org CVS.
904 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
906 * Check for valid socket connection in client entries before
907 sending any messages. Fixes a crash, but doesn't fix some
908 other underlaying bug that is lurking there. Affected
909 file silcd/packet_send.c.
911 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
913 * $usermode, $cumode and $cumode_space expandos shouldn't do
914 anything with non-SILC server records. Affected file
915 irssi/src/silc/core/silc-expandos.c
917 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
919 * Fixed the silc_net_check_[host/local]_by_sock to support
920 IPv6 bound sockets as well. Now they can return IPv6 addresses
921 as well. Affected file lib/silcutil/silcnet.c.
923 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
924 Affected lib/silcutil/unix/silcunixnet.c.
926 * Fixed ID rendering (at least on some platforms, not NetBSD)
927 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
929 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
931 * Added silc_hash_public_key and silc_hash_public_key_compare
932 functions to be used with SilcHashTable. They can be used to
933 hash public keys and compare public keys in hash table. Affected
934 file lib/silcutil/silcutil.[ch].
936 * Added support for specifying multiple public keys for Client
937 connection section in server configuration file. This makes it
938 possible to accept multiple public keys from same host, or to
939 make a section that accepts any incoming host, and have the
940 accepted public keys listed in the section.
942 Added functions silc_sever_[find/get]_public_key, added the
943 support for this actually to all connection sections but only
944 the Client section is currently allowed to specify multiple
947 Affected files are silcd/server.c, server_internal.h,
948 command.c, protocol.c, server_util.[ch], packet_receive.c.
950 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
952 * Merged Irssi 0.8.2 from irssi.org CVS.
954 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
956 * If silc_debug is TRUE, also output standard logging messages
957 to stderr with the debug output.
959 Made silc_log_reset_all() flushing all channels before returning.
960 Also fixed some documentation typos.
962 Affected files are lib/silcutil/silclog.[ch].
964 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
966 * Fixed the server to check correctly the amount of connections
967 from single host, by checking also the type of the connection.
968 Fixed also the comparison of number of connections and number
969 of allowed connections. Affected files are silcd/server.c,
972 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
974 * Fixed the USERS command reply to save the user's mode on the
975 channel as well. Fixed JOIN command reply to check whether a
976 client is on channel already and not join it twice. Affected
977 file lib/silcclient/command_reply.c.
979 * Added new file silc-expandos.c into irssi/silc/core/ to return
980 various stuff for various signal for the statusbar etc. updating.
981 Now Irssi SILC client prints channel user modes etc. on the
984 * The user mode (like server/router operator changes) is now shown
985 on the Irssi SILC client's statusbar. The affected files are
986 irssi/src/silc/core/client_ops.c, silc-expandos.c.
988 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
990 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
991 to SILC_SCHEDULE_[UN]LOCK macros.
993 * Added more error printing to logs in server code. Affected
994 files silcd/server.c and silcd/protocol.c.
996 * Fixed -S option parsing in Irssi SILC Client. Affected file
997 irssi/src/silc/core/silc-core.c.
999 * Added silc_buffer_alloc_size function. Affected file is
1000 lib/silcutil/silcbuffer.h.
1002 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1004 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1005 constants. Affected files in
1006 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1009 * Changed the internal SFTP Memory FS table to const. Affected
1010 file lib/silcsftp/sftp_fs_memory.c.
1012 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1014 * Fixed the buffer formatting and unformatting routines to
1015 check the size of 64 bits types with sizeof(). Affected
1016 file is lib/silcutil/silcbuffmt.c.
1018 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1020 * Removed 0.6.x backwards support.
1022 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1024 * Changed all integer type names:
1025 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is

1032 silc_net_gethostbyname[_async]. If it is TRUE it will return
1033 IPv6 address over IPv4. If FALSE IPv4 address is returned
1034 even if IPv6 address was found. Affected files
1035 lib/silcutil/silcnet.[ch].
1037 * Added support silc_net_create_connection[_async] to fallback
1038 to IPv4 address if IPv6 address could not be used (like if
1039 it doesn't work on a specific system). Affected file in
1040 lib/silcutil/unix/silcunixnet.c.
1042 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1051 application does not need to define them. Affected file
1052 includes/silcincludes.h.
1054 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1055 old name went against naming convention. Applications now
1056 include "silcclient.h" instead of "clientlibincludes.h".
1057 Removed includes/clientlibincludes.h, it is redundant now.
1059 * Renamed includes/version.h to silcversion.h.
1061 * Added really preliminary support for OS/2 into the util
1062 library. Only thread & mutex API is implemented, others
1063 are still to be implemented. Created the lib/silcutil/os2/
1064 directory. Created also file includes/silcos2.h.
1066 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1097 * Added `user_count' to the SilcChannelEntry which now tells the
1098 number of users on the channel. The user count is now saved
1099 in normal server of global channels as well. Affected files
1100 silcd/server.c, idlist.h, packet_receive.c and command.c.
1102 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1103 include file utility functions.
1105 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1106 instead of calling directly OS routines.
1108 * Fixed NICK change printing in Irssi SILC Client. Fixed
1109 KICKED notify printing in Irssi SILC Client. Affected file
1110 irssi/src/silc/core/client_ops.c.

1118 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1119 the SKE interface a bit.
1121 * Fixed padding problem in PKCS#1. The padding was not actually
1122 random since the random number generator was used incorrectly.
1123 This security bug affects only when encrypting with PKCS#1, and
1124 it is not currently used at all in SILC. SILC only use signing
1125 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1182 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1184 * Fixed command line parameter handling. All SILC initialization
1185 is now done in silc_core_init() which also fixes autoconnecting
1188 Affected files irssi/src/silc/core/silc-core.c,
1189 irssi/src/fe-text/silc.c.
1191 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1193 * Added new configuration options and blocks:
1194 keepalive_secs, reconnect_count, reconnect_interval,
1195 reconnect_interval_max, reconnect_keep_trying and
1196 require_reverser_lookup. Added ConnectionParam block, and
1197 implemented the connection parameters when connecting as
1198 initiator and when accepting connections as responder.

1210 the connection configuration object from the SilcServerConnection
1211 object instead of finding it during the connecting phase.
1212 Added the configuration object to SilcServerConnection struct.
1213 Affected files silcd/server_internal.h, server.c.
1215 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1217 * Add the client on channel after it was resolved at the
1218 channel message receiving, and it was not already on the
1219 channel. Affected file lib/silcclient/client_channel.c.
1221 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1237 authentication to be set at the same time.
1239 Added `prefer_passphrase_auth' setting in config file which
1240 can be used to set to prefer passwd auth if both passwd and
1241 public key is set. If not set, public key is preferred.
1242 This has effect only when being initiator (responder will try
1245 Added support for authentication with passphrase and public key
1246 at the same time. The passphrase is tried first always since
1247 it is faster to check.
1249 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1251 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1297 * Fixed the file transfer's key agreement payload to include
1298 zero port also if the hostname is NULL because it could not
1301 Call file transfer monitor callback now also if error occurs
1302 during key agreement protocol.
1304 Changed the silc_client_file_send interface to return the
1305 SilcClientFileError instead of session id. The session ID
1306 is returned into pointer provided as argument.
1308 Check that the file exists locally before sending the
1309 file transfer request at all.
1311 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1313 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1345 the table with foreach callback. The current entry may
1346 become invalid in the callback but it was referenced after
1347 the callback returned.
1349 Do not allow auto rehashing of hash table during the
1350 silc_hash_table_foreach operation, for same reasons as it is
1351 not allowed for SilcHashTableList. Affected files are
1352 lib/silcutil/silchashtable.[ch].

1375 users list to SilcHashTable. The affected files are
1376 lib/silcclient/idlist.[ch].
1378 * Fixed a bug in hash table tarversing. While the hash table
1379 is traversed with SilcHashTableList the table must not be
1380 rehashed. It is now guaranteed that auto rehashable tables
1381 are not rehashed while tarversing the list. Also defined that
1382 silc_hash_table_rehash must not be called while tarversing
1383 the table. Added function silc_hash_table_list_reset that must
1384 be called after the tarversing is over. The affected files are
1385 lib/silcutil/silchashtable.[ch].
1387 * Changed all hash table traversing to call the new
1388 silc_hash_table_list_reset in server and in client library.
1390 * Added function silc_client_on_channel to return the
1391 SilcChannelUser entry if the specified client entry is joined
1392 on the specified channel. This is exported to application as
1393 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1399 not only if !cmd->pending. Affected file silcd/command.c.
1401 * Fixed the WHOWAS command's reply sending to support the
1402 lists correctly. Affected file silcd/command.c.
1404 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1406 * When sending JOIN command to router for processing the
1407 sender's old command identifier was not saved back to the
1408 sender's command context, fixed now. The affected file is
1411 * Create the key in JOIN command of the router did not return
1412 the channel key, added check for this. Affected file is
1415 * Fixed a channel ID update bug in JOIN command reply. Do
1416 not directly upgrade the ID but call the function
1417 silc_idlist_replace_channel_id if the ID was changed.
1418 Affected file silcd/command_reply.c.
1420 * Fixed memory leaks from command calling if it would fail.

1508 local entry will always get the unformatted nickname.
1509 Affected file lib/silcclient/idlist.c.
1511 * Fixed some double frees from client library commands.
1512 Affected file is lib/silcclient/command.c.
1514 * Fixed CUMODE command in server to assure that no one can

1531 remote hostname and IP address before starting the key
1532 exchange with server. The affected file is
1533 lib/silcclient/client.c.
1535 * The server's public key is now saved using the IP address
1536 of the server and not the servername for the filename.
1537 The hostname public key filename is checked as an fall back
1538 method if the IP address based filename is not found.
1540 Fixed the GETKEY command to save the fetched server key
1541 in correct filename.
1543 Print the remote server's hostname now when new key is
1544 received during connection process. Affected file is

1555 was sent using silc_server_send_notify_to_channel function.
1556 Affected file silcd/command.c.
1558 * Fixed silc_server_send_notify_kicked to send the kicker's
1559 Client ID also, it was missing. Affected files are
1560 silcd/command.c, silcd/packet_send.[ch].
1562 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1564 * Do not save client history information in SERVER_SIGNOFF.
1565 Fixes the bug in normal server that it does not detect
1566 the client becoming valid after the server becomes back
1567 online. Affected file silcd/server_util.c.
1569 * Added `sock_error' field into the SilcSocketConnection
1570 context. When error occurs during socket operation (read
1571 or write) the error is saved. Added also new function
1572 silc_socket_get_error to return human readable socket error
1573 message. Affected files are lib/silcutil/silcsockconn.[ch],
1574 lib/silcutil/unix/silcunixsockconn.c, and
1575 lib/silcutil/win32/silcwin32sockconn.c.
1577 * The server now prints the socket error message in the
1578 signoff for client. Affected file silcd/server.c.
1580 * Fixed the `created' channel information sending from router
1581 to server in JOIN command. Checks now whether the channel
1582 really was created or not and set it according that.
1584 Fixed the JOIN command to use the client entry's current
1585 ID during the joining procedure instead of the one it sent
1586 in the command (it is checked though), since it can change
1587 between the packet processing and command processing, and
1588 would just case unnecessary pain in the client end. Affected
1589 file silcd/command.c.
1591 * Fixed a channel key payload sending to use correct channel
1592 ID when the server was forced to change the channel's ID by
1593 router. Router sent the key payload with the old Channel ID.
1594 Affected file silcd/packet_receive.c.
1596 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1598 * Call silc_server_save_channel_key only if the key payload
1599 was provided in the JOIN command's command reply. Affected
1600 file silcd/command_reply.c.
1602 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1604 * Fixed silc_mp_sizeinbase to return the value correctly with
1605 MPI. Affected file lib/silcmath/mp_mpi.c.
1607 * Fixed the stop_server signal to correctly stop the scheduler
1608 and gracefully stop the server when SIGTERM or SIGINT signals
1609 are received. Affected file silcd/silcd.c.
1611 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1613 * Simple handling of TERM and HUP signals. Also added some log
1614 flushing call around. Affected file is
1617 * Fixed small bugs in silclog.c. Now buffering output will take
1618 effect after 10 seconds since startup: This will ensure that
1619 no important startup messages are lost. Also output redirection
1620 will preserve original format ([Date] [Type] message).
1621 Affected file is lib/silcutil/silclog.c.
1623 * Added two options to the config file, in the logging section:
1624 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1625 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1627 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1629 * Do not print the warning about log files not being initialized
1630 more than once to avoid excess logging. Affected file is
1631 lib/silcutil/silclog.c.
1633 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1634 the SIM copying in make install in Makefile.am.pre.
1636 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1638 * Rewritten silclog APIs. Globally interesting changes follows:
1639 silc_log_set_files() changed to silc_log_set_file().
1640 silc_log_set_callbacks() changed to silc_log_set_callback().
1641 ROBOdoc documented silclog header file.
1642 SilcLogCb now returns bool to wether inihibit the default
1643 handler or not (to keep the old behaviour return always TRUE).
1644 The new APIs should also fix the problem of the
1645 silcd_error.log file that was written in the current directory.
1648 Log files streams will remain opened after silc_log_set_file()
1649 call, means less CPU usage notably on high traffic servers.
1650 File streams are now full buffered, and flushed to the disk
1651 every 5 minutes, lesses HD activity and CPU usage.
1652 Messages can be redirected, allowing admins to configure
1653 one single logfile for all server messages.
1654 the silc_log_quick global variable to activate fast-logging.
1655 Affected files lib/silcutil/silclog.[ch]
1657 * Changed some code to conform new silclog APIs. Affected
1658 files are doc/example_silcd.conf.in, silcd/server.c
1659 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1662 * Fixed a memory leak that could occur in some situations.
1663 Affected file silcd/serverconfig.c.
1665 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1667 * Added the silc_client_del_client to remove the client from
1668 all channels as well. Affected file lib/silcclient/idlist.c.
1670 * Fixed the client library to correctly remove the client
1671 from all channels when the client entry is being destroyed.
1672 Affected file lib/silcclient/client_notify.c, command.c.
1674 * Added auto-nicking support to the client library. If the
1675 applicatio now sets client->nickname it will be sent to the
1676 server after connecting by the library. This way for example
1677 SILCNICK (or IRCNICK) environment variables will have effect
1678 and always change the nickname automatically to whatever
1679 it is wanted. Affected file lib/silcclient/client.[ch].
1681 * Renamed silc_server_command_bad_chars to the
1682 silc_server_name_bad_chars and moved it to the
1683 silcd/server_util.[ch]. Added also new function
1684 silc_server_name_modify_bad to return nickname that
1685 includes bad characters as new nickname without those
1686 bad characters. This check and modify is now used in
1687 silc_server_new_client when the username is initially set
1688 as nickname, so it must be checked to be valid nickname.
1689 Affected file silcd/packet_receive.c.
1691 * The nickname length is now taken from the packet for real
1692 and not trusted to strlen() since it clearly can return
1693 wrong length for nickname including bad characters. This
1694 also applies to channel names. Affected file silcd/command.c.
1696 * Removed the lib/silcsilm/modules directory. Modules are now
1697 compiled into the lib/silcsim. Fixed the copying of the
1698 modules to follow symbolic links in Makefile.am.pre.
1700 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1702 * Fixed silc_string_regexify list creation. Fixes bugs with
1703 BAN and INVITE commands in server. The affected file is
1704 lib/silcutil/unix/silcunixutil.c.
1706 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Removed the command destructor entirely from the server's
1709 command and command reply routines. It is not needed, and
1710 its usage was buggy and caused crashes. Affected files are
1711 silcd/command[_reply].[ch].
1713 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1715 * Cancel protocol and NULL sock->protocol if timeout
1716 occurred during protocol. Affected file silcd/server.c.
1718 * Cancel protocol timeouts always before calling the final
1719 callback, to assure that after final callback is called
1720 no other state will be called for the protocol anymore.
1721 Affected file silcd/protocol.c.
1723 * Print error log if incoming connection configuration could
1724 not be found. Affected file silcd/server.c.
1726 * Fixed JOIN command to correctly save the founder mode
1727 to the client on normal SILC server, when the channel
1728 was created by the router. Affected file silcd/command.c.
1730 * Fixed LIST command (hopefully) to send correct reply
1731 packets. Affected file silcd/command.c.
1733 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * The silc_packet_receive_process now returns FALSE if the
1736 read data was invalid packet, and TRUE if it was ok.
1738 The server now checks that if unauthenticated connection
1739 sends data and its processing fails the server will close
1740 the connection since it could be a malicious flooder.
1742 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1744 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1746 * Make sure the warning about error opening a log file is
1747 printed only once and not everytime it fails (produces
1748 too much useless log). Affected file lib/silcutil/silclog.c.
1750 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1752 * Made the silc_server_daemonise() function more readable.
1753 Affected file silcd/server.c.
1755 * Pid file is now optional, the user may comment it out from
1756 the config file. Removed define SILC_SERVER_PID_FILE, we
1757 don't need a default any longer. Affected file
1758 configure.in.pre, lib/Makefile.am.pre.
1760 * Make some use of the pid file. The server now dies at startup
1761 if it detects a valid pid file on his path. The server would
1762 die anyway in this circumstance, because of the bind() failure.
1763 Affected file silcd/silcd.c.
1765 * No longer compiling lib/dotconf.
1767 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1769 * Fixed JOIN command parsing not to crash. Affected file
1770 lib/silcclient/command.c.
1772 * Fied the NICK_CHANGE notify to add the new client entry
1773 even it is resolved. This removes an <[unknown]> nick
1774 thingy bug in the client. Affected file is
1775 lib/silcclient/client_notify.c.
1777 * Do not try to allocate 0 bytes (efence does not like it)
1778 in lib/silccore/silccomand.c when encoding payload.
1780 * Do not take IRCNICK as nickname in Irssi SILC client since
1781 it is not possible to set nickname before hand connecting
1782 the server (TODO has an entry about adding auto-nicking
1785 * Changed the silc_server_command_pending to check whether
1786 there already exists an pending entry with the specified
1787 command, command identifier and pending callback. This is
1788 to fix IDENTIFY and WHOIS related crashes that may register
1789 multiple pending commands with same identifier. Affected
1790 file silcd/command.c.
1792 * Fixed the server to reconnect to the router even if it
1793 was already reconnecting and EOF was received. This to
1794 fix a possibility that the server wouldn't ever try to
1795 auto-reconnect to the router. Affected file silcd/server.c.
1797 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1799 * Fixed the server's password authentication to use the
1800 length of the locally saved password, and not the one
1801 sent in the packet. Affected file silcd/protocol.c.
1803 * Fixed same password authentication problem in the
1804 Authentication Payload handling routines in
1805 lib/silccore/silcauth.c.
1807 * Yet another password authentication problem fixed with
1808 channel password handling in silcd/command.c.
1810 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1812 * If first character of string in silc_parse_userfqdn is '@'
1813 then do not parse it. Affected file is
1814 lib/silcutil/silcutil.c.
1816 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1818 * Fixed minor bug in IDENTIFY command reply sending, which
1819 caused various weird problems during JOIN when it was
1820 resolving names for users. Affected file silcd/command.c.
1822 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * Fixed the IDENTIFY command reply sending to chech better valid
1825 clients. It was possible to send incomplete list of replies.
1826 Affected file silcd/command.c.
1828 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1830 * Added silc_client_command[s]_[un]register functions now to
1831 dynamically register the commands in client library. Removed
1832 the static table of commands. This allows the client library
1833 to call commands without causing the application to know about
1834 what commands library has called.
1836 Removed the INFO command reply kludge to detect when the command
1837 was called by library. Now library use its own command reply
1838 function for INFO command.
1840 Added function silc_client_command_call to call a command.
1841 Application can use it to call command, not access the structure
1844 Now all commands that are sent by the client library (not
1845 explicitly sent by application) use own command reply functions.
1847 Affected files around lib/silcclient/ and in
1848 irssi/src/silc/core/.
1850 * Fixed the WHOIS command reply sending to chech better valid
1851 clients. It was possible to send incomplete list of replies.
1853 Fixed the WHOIS and IDENTIFY to send the request to router
1854 if normal server did not do it and did not find any results.
1856 Affected file silcd/command.c.
1858 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1860 * Moved the internal data from SilcClient context into its
1861 own file, not accesible to application. Affected files
1862 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1863 and other files in client library.
1865 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1867 * Added doc/examples installation target in Makefile.am.pre.
1870 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1872 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1873 commands the found client entry will be removed from the
1874 cache, after notifying application about the error. Affected
1875 file lib/silcclient/command_reply.c.
1877 * Changed the /MSG to check for exact nickname user gave, and
1878 not let `nick' match `nick@host' if it is only one found. Now,
1879 user must type the exact nickname (like nick@host2) even if
1880 there are no more than one same nicks found. This is to avoid
1881 a possibility of sending nickname to wrong nickname since
1882 `nick' could match `nick@host'. Affected file is
1883 irssi/src/core/silc-servers.c.
1885 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1887 * Do not print "you are now server operator" or similar when
1888 giving /away command. Affected files are
1889 irssi/src/silc/core/client_ops.c, silc-servers.h.
1891 * Made the silc_server_command_pending_error_check to send
1892 the same command reply payload it received back to the
1893 original sender of the command. This way all arguments
1894 that was received by the server will be received by the
1895 client too. Affected file silcd/command.c.
1897 * Added the silc_idcache_add to return the created cache entry
1898 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1900 * Add global clients to expire if they are not on any channel.
1901 This is because normal server will never know if they signoff
1902 if they are not on any channel. The cache expiry will take
1903 case of these entries. This is done by normal servers only.
1904 The affected files are silcd/command_reply.c,
1905 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1907 * If server receives invalid ID notification for WHOIS or
1908 IDENTIFY and the ID exists in the lists, it is removed.
1909 Affected file silcd/command_reply.c.
1911 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1912 in client then client entry that it matches is searched and
1913 the nickname is printed on the screen for user. Affected
1914 file irssi/src/silc/core/client_ops.c.
1916 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Use cache entry expire time in the LIST command reply to
1919 purge old entries from the cache after the LIST command
1920 reply has been received. This way we don't have non-existent
1921 entries in the cache for too long. Affected file is
1922 silcd/command_reply.c.
1924 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1926 * If we are normal server, and we've not resolved client info
1927 in WHOIS or IDENTIFY from router, and it is global client,
1928 we'll check whether it is on some channel. If it is not
1929 then we cannot be sure about its validity and will resolve it
1930 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1931 file silcd/command.c.
1933 * Search channel by name (if possible) rather than by ID
1934 in IDENTIFY command's command reply. Affected file is
1935 silcd/command_reply.c.
1937 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1939 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1940 Updated specs and implemented it. Affected file silcd/command.c,
1941 silcd/packet_send.c and silcd/packet_receive.c.
1943 * Implemented the <founder auth> payload handling in the JOIN
1944 command. If provided all conditions for channel joining
1945 except requirement to provide correct passphrase can be
1946 overrided by the channel founder. Updated the protocol specs.
1947 Affected file silcd/command.c.
1949 Added support for founder auth in JOIN command in client
1950 library. Fixed the parsing of the JOIN command now to support
1951 all options as they should be. The affected file is
1952 lib/silcclient/command.c.
1954 * Optimized the WHOIS and IDENTIFY commands to send the request
1955 to router only if it includes nicknames or other names. If
1956 they include only IDs then check the local cache first before
1957 routing. Affected file is silcd/command.c.
1959 * Added channels topic announcements. Affected file is
1960 silcd/packet_receive.c and silcd/server.c.
1962 * Fixed the silc_server_send_notify_topic_set to really destine
1963 the packet to channel. Affected file silcd/packet_send.c.
1965 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1966 library. Affected file lib/silcclient/client_notify.c.
1968 * Added UMODE announcements. Affected file silcd/server.c.
1970 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1972 * Memory leak fixes in:
1974 lib/silcutil/silcsockconn.c
1975 lib/silcske/silcske.c
1976 lib/silcske/groups.c
1978 lib/silccrypt/silcpkcs.c
1979 lib/silccore/silccommand.c
1980 lib/silccore/silcidcache.c
1985 * ROBOdoc documented the lib/silcske/groups.h file and a
1986 bit changed the interface for better.
1988 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1990 * Update the client entry context in the ID cache after
1991 nick change. Affected file lib/silcclient/command.c.
1992 Fixes the CUMODE command when regaining founder privileges,
1993 and a little WHOIS problem.
1995 * Fixed silc_net_gethostbyname to correctly call the
1996 inet_ntop. Affected file lib/silcutil/silcnet.c.
1998 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2000 * Added IPv6 support checking to the configure.in.pre, added
2001 also --enable-ipv6 option to override the check. Affected
2002 file configure.in.pre.
2004 * The silc_thread_create now calls the start function
2005 directly if threads support is not compiled in. Removes
2006 ugly #ifdef's from generic code. Affected files are
2007 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2009 * Added silc_net_gethostby[name/addr]_async to asynchronously
2010 resolve. Affected files are lib/silcutil/silcnet.[ch].
2012 * Added support for rendering IPv6 based server, client and
2013 channel IDs. Affected file lib/silcutil/silcutil.c.
2015 * Added support for creating IPv6 based server IDs. Affected
2016 file is silcd/serverid.c.
2018 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2020 * Added silc_net_gethostby[addr/name] into the
2021 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2022 routines. Added silc_net_is_ip[4/6]. Affected file is
2023 lib/silcutil/unix/silcunixnet.c. All routines that take
2024 address as argument now supports both IPv4 and IPv6 addresses.
2026 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2028 * Fixed LIST command reply sending in server. Affected file
2031 * Server now sends the kicker's client ID in the KICK notify
2032 to the kicked client. Affected file silcd/command.c.
2034 * The client library now parses the kickers client ID and
2035 UI displays it. Affected files lib/silcclient/client_notify.c
2036 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2038 * Made all payload parsing function prototypes consistent.
2039 They all take now const unsigned char * and uint32 pair as
2040 the payload data instead of SilcBuffer. Changes all around
2041 the source tree. Other unsigned char* -> const unsigned char*
2042 changes around the tree as well.
2044 * Optimized SFTP client and server packet sending not to
2045 allocate new buffer for each packet but to recycle the
2046 first allocated buffer. Affected files are
2047 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2049 * Optimized the SFTP client to use SilcList instead of
2050 SilcDList for requests, because it is faster. Affected file
2051 is lib/silcsftp/sftp_client.c.
2053 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2054 into lib/silccore/silcid.[ch].
2056 Renamed silcpayload.[ch] into silcargument.[ch].
2058 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * If client entry is deleted with active key agreement
2061 session, abort the session.
2063 The silc_client_abort_key_agreement now calls the completion
2064 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2066 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2069 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2071 * Don't use __restrict in older GCC's. Affected file is
2072 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2074 * silc_net_localhost now attempts to reverse lookup the
2075 IP/hostname. Affected file lib/silcutil/silcnet.c.
2077 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2078 command. It can be used to gain founder privileges at
2079 the same time when joining the channel.
2081 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2082 kicker's client ID as well. Updated protocol specs.
2084 Defined that the server must send SILC_COMMAND_IDENTIFY
2085 command reply with error status to client who sent
2086 private message with invalid client ID.
2088 Updated the protocol specification.
2090 * Added silc_server_send_command_reply to send any
2091 command reply. Affected file silcd/packet_send.[ch].
2093 * Added silc_id_payload_encode_data to encode ID payload
2094 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2096 * The server now send IDENTIFY command reply with error
2097 status if client ID in private message is invalid. Affected
2098 file silcd/packet_receive.c.
2100 * Save the server key file with server's IP address in
2101 the filename instead of hostname. The affected file is
2102 irssi/src/silc/core/client_ops.c.
2104 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2106 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2109 * Added libtool support for compiling shared objects in
2110 lib/silcsim. Affected file configure.in.pre and
2111 lib/silcsim/Makefile.am. Original patch by cras.
2113 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2115 * Pid file configuration, and server's config file fixes
2116 patch by toma. Updated CREDITS file.
2118 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Fixed silc_client_channel_message to not try to decrypt
2121 the message twice if it resolved the destination client
2122 information. This could cause of dropping one channel
2123 message. Affected file lib/silcclient/client_channel.c.
2125 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2127 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2128 lib/silcclient/client.c. This function is used when the SILC
2129 Client is run under some other scheduler, or event loop or
2130 main loop. On GUI applications, for example this may be
2131 desired to used to run the client under the GUI application's
2132 main loop. Typically the GUI application would register an
2133 idle task that calls this function multiple times in a second
2134 to quickly process the SILC specific data.
2136 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2138 * Fixed silc_server_drop() for dropping the supplementary
2139 groups as well, this could cause a security hole on some
2142 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2144 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2147 * Write PID file after dropping privileges. Added -F option
2148 to run server on foreground. A patch by debolaz.
2149 Affected files silcd/server.c, silcd/silcd.c.
2151 * Fixed MOTD to return the MOTD file server name. Affected
2152 file silcd/command.c.
2154 * Added INFO command reply handling to the Irssi SILC Client.
2155 Affected file irssi/src/silc/core/client_ops.c.
2157 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2159 * Fixed the silc_idcache_list_* routines to really support
2160 the dynamic list. Fixes a crash. Affected file is
2161 lib/silccore/silcidcache.c.
2163 * Fixed the LIST command reply to really call LIST command's
2164 pending callbacks. Affected file silcd/command_reply.c.
2166 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2168 * Update conn->local_entry->nickname after giving NICK
2169 command. Affected file lib/silcclient/command.c.
2171 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2173 * Added the [pid] option to the silcd configuration file
2175 Affected files: serverconfig.[ch] and silcd.c
2177 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Save fingerprint in WHOIS command reply in server.
2180 Affected file silcd/command_reply.c.
2182 * Fixed NICK commands pending callback registration.
2183 Affected file lib/silcclient/command.c.
2185 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2187 * Use ++server->cmd_ident when sending commands in server,
2188 instead of random number. Affected file silcd/command.c.
2190 * Fixed GETKEY command reply to call actually GETKEY pending
2191 command callbacks. Affected file silcd/command_reply.c.
2193 * A bit stricter check for nicknames. Check for same nickname
2194 in NICK command also. Affected file silcd/command.c.
2196 * Do not call INFO command everytime client ID changes, only
2197 during first connecting. Affected file lib/silcclient/client.c.
2199 * Set the new nickname only after successful command reply for
2200 NICK command is returned by server. Affected file
2201 lib/silcclient/command.c.
2203 * Remove nicknames from nicklist during server_signoff notify.
2204 Should fix /NAMES bit more. The affected file is
2205 irssi/src/silc/core/silc-channels.c.
2207 * Added `fingerprint' field to the SilcIDListData in the
2208 silcd/idlist.h to hold the fingerprint of the client's
2211 Send the fingerprint of the client's public key in WHOIS
2214 Affected files silcd/command.c, and silcd/idlist.[ch].
2216 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2217 create fingerprint from given data.
2219 * Show the fingerprint of the client's public key in WHOIS.
2220 Affected files irssi/src/module-formats.[ch] and
2221 irssi/src/silc/core/client_ops.c.
2223 * Format the multiple same nicknames also during JOIN and
2224 NICK_CHANGE notifys. Affected file is
2225 lib/silcclient/client_notify.c.
2227 * Do not print error on screen for invalid private message
2228 payload since it can come if someone is sending private
2229 messages with wrong key. Affected file
2230 lib/silccore/silcprivate.c.
2232 * Fixed multiple concurrent /PING crash. Affected file
2233 lib/silcclient/command.c.
2235 * Changed the wrong ID encoding. All IP addresses must be
2236 in MSB first order in encoded format. They were encoded
2237 wrong and was in LSB format. Affected files are
2238 silcd/serverid.c, lib/silcutil/silcutil.c.
2240 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2242 * Call the `connect' client operation through the scheduler
2243 in case of error. Affected file lib/silcclient/client.c.
2245 * Call the `failure' client operation even if the error
2246 occurred locally during a protocol. Affected file is
2247 lib/silcclient/protocol.c.
2249 * Added support of sending LIST command to router from normal
2250 server. This way normal server can get list of all channels
2251 in the network too. Fixed the channel list sending in the
2252 server too. Affected files are silcd/command.c, and
2253 silcd/command_reply.[ch].
2255 * Added silc_server_update_channels_by_server and
2256 silc_server_remove_channels_by_server. They are used during
2257 disconnection of primary router and in backup router protocol.
2258 Affected file silcd/server_util.[ch], silcd/server.c and
2259 silcd/server_backup.c.
2261 * Fixed channel adding to global list in IDENTIFY command
2262 reply in server. Affected file silcd/command_reply.c.
2264 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2266 * If the incoming packet type is REKEY or REKEY_DONE process
2267 that packet always synchronously. Fixes yet another MAC
2268 failed error on slow (dialup) connections. Affected file
2269 lib/silcclient/client.c and silcd/server.c.
2271 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * Call check_version SKE callback for initiator too. Affected
2274 file lib/silcske/silcske.c.
2276 * Implemented fix for security hole found in the SKE that was
2277 fixed in the specification few days back; the initiator's
2278 public key is now added to the HASH value computation.
2279 Added backwards support for the old way of doing it too, for
2280 old clients and old servers. Affected file is
2281 lib/silcske/silcske.c.
2283 * Enabled mutual authentication by default in SKE. If initiator
2284 is not providing mutual authentication the responder will
2285 force it. This will provide the proof of posession of the
2286 private key for responder. The affected files are
2287 lib/silcclient/protocol.c and silcd/protocol.c.
2289 * Do not cache anymore the server's public key during SKE.
2290 We do mutual authentication so the proof of posession of
2291 private key is done, and if the server is authenticated in
2292 conn auth protocol with public key we must have the public
2293 key already. Affected file silcd/protocol.c.
2295 * Added new global debug variable: silc_debug_hexdump. If
2296 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2297 file lib/silcutil/silclog.[ch].
2299 * Fixed compilation warning due to char * -> const char *.
2300 Affected files lib/silcutil/silcnet.h, and
2301 lib/silccore/silcauth.[ch].
2303 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2305 * Fixed CMODE command when new channel key was created. If
2306 the creation failed the old key was removed. Next time giving
2307 same command would crash the server since the old key was
2308 freed already. Affected file silcd/command.c.
2310 * Fixed the silc_server_announce_get_channels to not crash
2311 on reconnect. Affected file silcd/server.c.
2313 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2315 * Added silc_log_set_debug_string function to set a regex
2316 string to match for debug output. Only the function names,
2317 or filenames matching the given debug string is actually
2318 printed. This way it is possible to filter out those debug
2319 strings that user is not interested in.
2321 Fixed a bug in silc_string_regexify.
2323 Affected files lib/silcutil/silclog.[ch], and
2324 lib/silcutil/unix/silcunixutil.c.
2326 * Changed the -d options in both server and Irssi SILC client
2327 to take the debug string as argument. Affected files
2328 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2330 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2332 * Added silc_hash_babbleprint to create a Bubble Babble
2333 Encoded fingerprint. The encoding is developed by Antti
2334 Huima (draft-huima-babble-01.txt), and it creates human
2335 readable strings out of binary data. Affected file
2336 lib/silccrypt/silchash.[ch].
2338 * Print the babble print now in addition of fingerprint as well
2339 in Irssi SILC client. Affected files are
2340 irssi/src/fe-common/silc/module-formats.[ch],
2341 irssi/src/fe-common/silc/core/client_ops.c.
2343 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Fixed a security problem found in SKE. The initiator's
2346 public key too is now added to the HASH hash value creation
2347 which is signed by the responder to create the SIGN value.
2348 This will prevent anyone in the middle to lie to the responder
2349 about the initiator's public key. If this is done now, the
2350 man in the middle will get caught. Updated the protocol
2353 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2355 * Better installation directory handling. Configure module
2356 paths and other paths automatically to example_silc* files
2357 in doc/. A patch by toma.
2359 * Fixed compiler warning from MPI library, and from SILC RNG.
2362 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2363 It can be configured with ./configure. A patch by toma.
2365 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * Find correct make to use in prepare-clean. A patch by
2368 toma. Affected file prepare-clean.
2370 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2372 * Added irssi variables use_auto_addr, auto_bind_ip,
2373 auto_bind_port and auto_public_ip.
2375 * Changed the interface for silc_client_send_key_agreement
2376 in lib/silcclient/silcapi.h
2380 irssi/src/silc/core/silc-core.c
2382 lib/silcclient/silcapi.h
2383 irssi/src/silc/core/silc-channels.c
2384 lib/silcclient/client_keyagr.c
2387 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2389 * Added silc_pkcs_public_key_compare to compare two
2390 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2392 * Check that the client who set the founder mode on the
2393 channel is the same client that is giving the founder
2394 mode to itself. It is done by comparing the saved public
2395 key (it is saved even in the authentication is passphrase).
2396 Affected file silcd/command.c.
2398 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2400 * Do not process packet for disconnected socket connection.
2401 Affected file lib/silccore/silcpacket.c.
2403 * Process the DISCONNECT packet through scheduler in the
2404 client library. Affected file lib/silcclient/client.c.
2406 * Fixed the silc_client_packet_parse to not to increase
2407 the packet sequence number if the conn->sock and the
2408 current socket connection is not same. This can happen
2409 for example during key agreement when the conn includes
2410 multiple socket connections (listeners). Affected file
2411 lib/silcclient/client.c.
2413 * The sender of the file transfer request now provides also
2414 the pointer (listener) for the key exchange protocol. If
2415 the listener cannot be created then it sends empty key
2416 agreement and lets the receiver provide the listener.
2418 Added `local_ip' and `local_port' arguments to the
2419 silc_client_file_send. If they are provided they are used,
2420 if not then it will attempt to find local IP address, if
2421 not found or bind fails then the remote client will provide
2424 Affected files are lib/silcclient/client_ftp.c and
2425 lib/silcclient/silcapi.h.
2427 * Extended the FILE SEND command to support defining the
2428 local IP and port for key exchange listener. They are
2429 optional. Affected file irssi/src/silc/core/silc-servers.c.
2431 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2433 * Defined to WHOIS command reply the sending of fingerprint
2434 of the client's public key (if the proof of posession of the
2435 corresponding private key is verified by the server).
2436 Updated to the protocol specification.
2438 * Added support of receiving the client's public key's
2439 fingerprint in command reply in client library. Affected
2440 file is lib/silcclient/command_reply.c, and
2441 lib/silcclient/idlist.[ch].
2443 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2445 * Do not send over 128 chars long nickname to the server
2446 in NICK command. Affected file lib/silcclient/command.c.
2448 * Do not send over 256 chars long channel names to the server
2449 in JOIN command. Affected file lib/silcclient/command.c.
2451 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2453 * Assure that silc_server_close_connection cannot be called
2454 twice for same socket context. Affected file is
2457 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2459 * Send error message to application if opening file for
2460 writing during file transfer fails. Affected file is
2461 lib/silcclient/client_ftp.c.
2463 Remove all file transfer sessions for a client that we're
2464 removing from ID cache.
2466 Affected file is lib/silcclient/client_ftp.c.
2468 * Fixed silc_net_addr2bin to return correct address. Affected
2469 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2471 * Fixed file transfer session removing on signoff notify.
2472 Affected file irssi/src/silc/core/silc-servers.c.
2474 * Added the SilcClientFileError to be returned in the monitor
2475 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2476 Affected file lib/silcclient/silcapi.h.
2478 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Fixed a crash in silc_client_ftp_free_sessions and
2481 silc_client_ftp_session_free_client. Affected file
2482 lib/silcclient/client_ftp.c.
2484 * Added `disabled' field in the SilcChannelEntry in the server
2485 to indicate if the server entry is disabled. Affected file
2486 silcd/idlist.h, silcd/command[_reply].c.
2488 * SILC server adds now /var/run/silcd.pid everytime it is
2489 started. Affected file silcd/silcd.c.
2491 * Added silc_server_packet_send_clients to send a packet to
2492 the provided table of client entries. Affected file
2493 silcd/packet_send.[ch].
2495 * Fixed a crash in client resolving in client_prvmsg.c in
2496 client library. Affected file lib/silcclient/client_prvmsg.c.
2498 * Do not actually remove the client directly from ID cache
2499 during SERVER_SIGNOFF, but invalidate it. This way we
2500 preserve the WHOWAS info for the client. Affected file
2501 silcd/server_util.c.
2503 * Fixed SERVER_SIGNOFF notify handling in the server. The
2504 server is now able to process incoming SERVER_SIGNOFF notify
2505 for a server that it doesn't even know about. It will remove
2506 the clients provided in the notify. Affected file
2507 silcd/packet_receive.c.
2509 * Check for partial packet in data queue after every packet that
2510 was found from the queue. Return and wait for more data if
2511 there is partial data in queue. Affected file is
2512 lib/silccore/silcpacket.c.
2514 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2516 * Added SilcClietFileError enum to indicate error in
2517 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2518 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2519 Affected files lib/silcclient/silcapi.h and
2520 lib/silcclient/client_ftp.c.
2522 * Check that newsize in silc_buffer_realloc is larger than
2523 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2525 * Added better monitor of file transfers. It now monitors
2526 key agreement protocol during the file transfer too. Added
2527 error reporting too. Affected files
2528 irssi/src/silc/core/silc-servers.c,
2529 irssi/src/fe-common/silc/module-formats.[ch].
2531 * Wrote a help file for FILE command.
2533 * Added silc_rng_global_get_byte_fast to get not-so-secure
2534 random data as fast as possible. Random data is read from
2535 /dev/urandom if available and from the SILC RNG if not
2536 available. It is used in padding generation. Affected file
2537 lib/silccrypt/silcrng.[ch].
2539 * All packets in client library are now processed synchronously.
2540 Optimized packet processing a lot. Affected file
2541 lib/silcclient/client.c.
2543 * All server connection packets are processing synchronously
2544 now in server, to optimize packet processing. Affected file
2547 * Include files are installed now only in Toolkit distribution
2548 if make install is given. Affected files: all Makefile.am's.
2550 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2552 * Assure that silc_client_notify_by_server_resolve does not
2553 resolve the client information multiple times. If it cannot
2554 be found by the first it cannot be found at all. Affected
2555 file lib/silcclient/client_notify.c.
2557 * Fixed WHOWAS command reply calling. Affected file
2558 lib/silcclient/command_reply.c.
2560 * Removed all references to silc_idlist_get_client from the
2561 Irssi SILC client since that call is internal call used by
2562 the library. The Irssi SILC client will use now client
2563 retrieval functions found in silcapi.h.
2565 * Fixed a bug in resolving nickname info before sending
2566 private message. It used freed memory. Affected file
2567 irssi/src/silc/core/silc-servers.c.
2569 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Assure my_channels statistics cannot go negative in server.
2572 Affected files silcd/server.c, silcd/server_util.c.
2574 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2578 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Win32 Toolkit changes. Affected files
2581 win32/silc.dsw, win32/libsilc/libsilc.def,
2582 win32/libsilcclient/libsilc.def,
2583 lib/silcutil/silcutil.c, and
2584 lib/sftp/sftp_fs_memory.c.
2586 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2588 * Added silc_net_localip to return local host's IP address.
2589 Affected file lib/silcutil/silcnet.[ch].
2591 * If key exchange or rekey protocol is active for a connection
2592 parse all packets syncronously since there might be packets
2593 in packet queue that we are not able to process without first
2594 processing packets before them. Affected file silcd/server,
2595 lib/silcclient/client.c.
2597 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2598 whether library should continue processing the packet.
2599 Affected file lib/silccore/silcpacket.h.
2601 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2602 SilcSFTPMonitorData to SFTP server to monitor various
2603 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2604 lib/silcsftp/sftp_server.c.
2606 * Added silc_file_size to return file size. Affected file
2607 lib/silcutil/silcutil.[ch].
2609 * Implemented the file transfer support for the client library.
2610 Added preliminary support for simple client to client one-file

2623 silcd/server.c and silcd/packet_receive.c.
2625 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2627 * Renamed silc_file_read and silc_file_write to functions
2628 silc_file_readfile and silc_file_writefile. Added function
2629 silc_file_open and silc_file_close. Affected files
2630 lib/silcutil/silcutil.[ch].
2632 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Resolve the client info when received private message or
2635 channel message for a client which nickname we don't know.
2636 Affected files lib/silcclient/client_prvmsg.c and
2637 lib/silcclient/client_channel.c.
2639 * Do not crash in /KEY if client is not connected. Affected
2640 file irssi/src/silc/core/silc-channels.c.
2642 * Added SilcClientStatus field to the SilcClientEntry in the
2643 lib/silcclient/idlist.h.
2645 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2646 is incomplete and is being resolved, it won't be resolved
2649 Make sure also that USERS command reply does not resolve
2650 twice information. Affected file is
2651 lib/silcclient/command_reply.c.
2653 Make sure that silc_client_get_clients_by_list does not
2654 resolve twice same information.
2656 * Check for valid client->id in the silc_server_free_client_data.
2657 Affected file silcd/server.c.
2659 * Fixed /GETKEY nick@server not to crash if the server entry
2660 is not found. Affected file lib/silcclient/command.c.
2662 * Fixed the silc_server_check_cmode_rights to check the
2663 requested modes correctly. Affected file silcd/command.c.
2665 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2667 * Better checks for non-printable chars in nick added.
2668 Affected file silcd/command.c.
2670 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2672 * Call the silc_server_udpate_servers_by_server in the
2673 primary router that comes back online in the backup resuming
2674 protocol. Otherwise it routes packets wrong. Affected file
2675 silcd/server_util.[ch], silcd/server_backup.c.
2677 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2679 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2680 lib/silcutil/silcbuffmt.[ch].
2682 * Redefined the SILC packet header to include the padding
2683 length. Affected file lib/silccore/silcpacket.[ch].
2685 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2686 length for maximum padding up to 128 bytes). Affected
2687 file lib/silccore/silcpacket.h.
2689 * Removed all backwards support for old 0.5.x MAC thingies.
2690 The SILC packet header change makes it impossible to be
2691 backwards compatible.
2693 * Send the ENDING packet with timeout in the backup resuming
2694 protocol. This is to assure that all routers has connected
2695 to the primary router. Affected file silcd/server_backup.c.
2697 * Changed the RNG to take the first IV from random data. It
2698 used to take it from zero actually. Changed the RNG also
2699 to use /dev/urandom during session. /dev/random is used
2700 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2702 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2704 * Changed the SILC packet header to have the first two bytes
2705 (the packet length) encrypted. Affected files aroung the
2706 code tree, lib/silccore/silcpacket.[ch]. Removed the
2707 SilcPacketCheckDecrypt callback. It is not needed anymore
2708 since the silc_packet_receive_process will determine now
2709 whether the packet is normal or special.
2711 * Implemented the unidirectional MAC keys. Affected files
2712 lib/silcske/silcske.c, silcd/protocol.c and
2713 lib/silcclient/protocol.c.
2715 * Implemented the packet sequence number to the MAC computation.
2716 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2717 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2718 lib/silcclient/protocol.c.
2720 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2722 * Allow backup router to announce servers. All servers
2723 announced by backup router are added to the global list
2724 automatically. Update hte server's socket to our primary
2725 router also when backup router announces a server.
2726 Affected file silcd/packet_receive.c.
2728 * Do not update the client->router in the function
2729 silc_server_udpate_clients_by_server if the client is on
2730 global list. We might fail to find any specific server
2731 for locally connected clients and local cell clients. They
2732 should still use the `from' and not `to' as client->router.
2733 This fixes backup router resuming protocol. Affected file
2734 silcd/server_util.c.
2736 * Decrease channel statistics count only if the channel
2737 deletion worked. Affected files are silcd/server.c and
2738 silcd/server_util.c.
2740 * Added silc_server_update_servers_by_server to update origin
2741 of all server entries. Used during backup router protocol.
2742 Affected files silcd/server_util.[ch], silcd/server.c. and
2743 silcd/backup_router.c.
2745 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2746 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2747 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2748 lib/silccrypt/silchmac.c.
2750 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2752 * Assure that router cannot reroute the same channel message
2753 to the sender. Affected file silcd/packet_receive.c.
2755 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2757 * Made better checks that the channel message is not sent
2758 to the router it came from. Affected file is
2759 silcd/packet_send.c. Fixed memory leak too.
2761 * Announce informations for incoming router connection, but
2762 only after checking if it is replaced by backup router.
2763 Affected file silcd/packet_receive.c.
2765 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * Fixed the backup resuming protocol to work in multiple
2768 router environment. Affected file silcd/server_backup.c.
2770 * Route packet only to one router in the function
2771 silc_server_packet_send_to_channel. Affected file is
2772 silcd/packet_send.c.
2774 * Fixed silc_server_send_notify_dest to set the broadcast
2775 flag. Fixed the silc_server_send_notify_topic to actually
2776 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2777 Affected file silcd/packet_send.c.
2779 * Changed the SFTP Filesystem interface. Changed the
2780 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2781 the filesystem operation function. The SilcSFTPFilesystem
2782 is now a context that is allocated by all filesystem allocation
2783 functions and it already includes the operations structure
2784 and filesystem specific context. It is given as argument
2785 now to the silc_sftp_server_start. This made the interface
2786 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2787 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2789 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2791 * Changed the backup router adding and getting interfaces
2792 in the server. The router that will be replaced by the
2793 specified backup router is now sent as argument. Affected
2794 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2797 * Added silc_net_addr2bin_ne to return the binary form of
2798 the IP address in network byte order. Affected files
2799 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2801 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2803 * Check for existing server ID in silc_server_new_server
2804 and in silc_server_connect_to_router_final and remove the
2805 old entry if it exists. Affected file silcd/packet_receive.c,
2808 * Send the channel message always to only one router, either
2809 in upstream or downstream. Affected file is
2810 silcd/packet_send.c.
2812 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2814 * Wrote the definition of the backup resuming protocol to the
2815 protocol specification.
2817 * Removed one redundant channel key generation from normal
2818 server during joining procedure. Removed one redundant
2819 channel key sending from server to router during joining
2820 procedure. Affected file silcd/command.c.
2822 * Made minor bugfixes to the backup router resuming protocol.
2823 Affected file silcd/server_backup.c, server.c.
2825 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2827 * Added --disable-asm configuration option. Affected files
2828 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2831 * Implemented the backup resuming protocol that is used to
2832 resume the primary router position in the cell after the
2833 primary router comes back online. Affected files
2834 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2835 and silcd/server_util.[ch].
2837 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2839 * Sleep two (2) seconds after sending QUIT command to server.
2840 Affected file lib/silcclient/command.c.
2842 * Assure that if outgoing data buffer is pending do not force
2843 send any data. Affected file silcd/packet_send.c.
2845 * Assure that if outgoing data buffer is pending do not force
2846 send any data. Affected file lib/silcclient/client.c.
2848 * Implemented the backup router support when the primary router
2849 goes down. The servers and routers can now use the backup
2850 router as new primary router without loosing connectivity.
2852 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2854 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2855 in the server to indicate disabled entry. All data read
2856 from the connection will be ignored and no data is sent
2857 for entry that is disabled. Affected files are
2858 silcd/idlist.h, silcd/server.c.
2860 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2862 * Created SFTP client and server test programs in the
2863 lib/silcsftp/tests directory.
2865 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2867 * Implemented memory filesystem (virtual filesystem) for
2868 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2871 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2873 * Implemented the SFTP (SSH File Transfer Protocol) to the
2874 lib/silcsftp. It includes SFTP client and SFTP server
2877 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2879 * Moved lib/silccore/silcprotocol.[ch] to the
2880 lib/silcutil library.
2882 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2883 take variable argument list pointer as argument. Affected
2884 file lib/silcutil/silcbuffmt.[ch].
2886 * Added silc_buffer_set function that is used to set data
2887 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2888 Affected file lib/silcutil/silcbuffer.h.
2890 * Changed various routines in the core library to use the new
2891 silc_buffer_set instead of allocating new buffer only for
2894 * Added 64-bit value formatting and unformatting support to the
2895 silc_buffer_[un]format routines. Affected file is
2896 lib/silcutil/silcbuffmt.[ch].
2898 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2899 to includes/bitmove.h.
2901 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * Fixed channel user mode saving in client library. Affected
2904 file lib/silcclient/command[_reply].c.
2906 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Defined the file transfer to the SILC Protocol. Added
2909 new packet type SILC_PACKET_FTP and defined File Transfer
2910 Payload. The mandatory file transfer protocol is SFTP
2911 (SSH File Transfer Protocol). Affected file in addition
2912 of the internet draft is lib/silccore/silcpacket.h.
2914 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2915 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2916 is used as part of backup router protocol when the primary
2917 router of the cell is back online and wishes to resume
2918 the position as primary router.
2920 * Redefined the MAC generation keys in the protocol. The
2921 same key is not used anymore in both direction. Both
2922 direction will now use different keys for sending and
2923 receiving. This fixes a potential security flaw. This
2924 change causes incompatibilities in the protocol.
2926 * Redefined also the MAC computation from the packet.
2927 An packet sequence number is now added to the MAC
2928 computation. This prevents possible replay attacks against
2929 the protocol. This change too causes incompatibilities
2932 Added `sequence' field to the SilcPacketContext to hold
2933 the current sequence number for the packet.
2935 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Added `created' field to the SilcIDListData in the file
2938 silcd/idlist.h to indicate the time when the entry was
2941 * Added `created' field to the SilcChannelEntry too. Affected
2942 file silcd/idlist.h.
2944 * Added `creation_time' aguments to all the announcement functions
2945 in the server. If it is provided then only the entries that
2946 was created after the provided time frame are actually
2947 announced. Affected file silcd/server.[ch].
2949 * The protocol says that the Channel ID's IP address must be
2950 based on the router's IP address. Added check for this in
2951 the silc_server_new_channel when processing incoming New Channel
2952 Payload. Affected file silcd/packet_receive.c.
2954 * Print out the correct version with --version in SILC client.
2955 Affected file irssi/src/silc/core/silc-core.c.
2957 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2959 * Fixed WHOWAS command to check for completnes of the client
2960 entry always, not just when the command is coming from client.
2961 Affected file silcd/command.c.
2963 * Added new function silc_server_packet_queue_purge to purge the
2964 outgoing data queue to the network. After the function returns
2965 it is guaranteed that the outgoing packet queue is empty.
2966 Affected file silcd/packet_send.[ch].
2968 * Purge the outgoing packet queue in the rekey protocol's final
2969 callback to assure that all rekey packets go to the network
2970 before quitting the protocol. Affected file silcd/server.c.
2972 * Added silc_client_packet_queue_parse as similar function as
2973 in server to the client library. The affected file is
2974 lib/silcclient/client.c.
2976 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * Splitted silcd/server.c and created silcd/server_util.[ch]
2979 for utility functions.
2981 * Added new socket flag SILC_SF_DISABLED to indicate that the
2982 connection is open but nothing can be sent to or received from
2983 the connection. Affected file lib/silcutil/silsockconn.[ch].
2984 The checking for disabled socket is checked in the low level
2985 silc_socket_write and silc_socket_read functions.
2987 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * Allow only nicknames and channel names that fits into the
2990 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2992 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2994 * When processing JOIN command reply in server check that if
2995 the channel exists in our global list we'll move it the local
2996 list. Affected file silcd/command_reply.c.
2998 * Fixed the check whether client is joined on the channel already
2999 in JOIN command. Affected file lib/silcclient/command.c.
3001 * Fixed the JOIN command reply to check whether the channel
3002 already exists. Affected file lib/silcclient/command_reply.c.
3004 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3006 * Added silc_ske_status_string to map the SKE error numbers
3007 to readable strings. The affected files are
3008 lib/silcske/silcske[_status].[ch].
3010 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3012 * Do not show the private channels on the WHOIS channel list
3013 as it is not allowed by the protocol. The affected file is
3016 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3018 * Assure that the packet length digged from the actual packet
3019 is something sensible in the silc_packet_decrypt_rest_special
3020 in lib/silccrypt/silcpacket.c.
3022 * Free and NULL the allocated pointer in silc_hmac_alloc if
3023 the HMAC allocation fails. The affected file is
3024 lib/silccrypt/silchmac.c.
3026 * Print the selected security properties to the log files in
3027 the server. Affected file silcd/protocol.c.
3029 * Add SKE's reference counter even if calling the completion
3030 callback manually. Otherwise it goes negative, although it
3031 does not cause any problems. The affected file is
3032 lib/silcske/silcske.c.
3034 * Remove the client entry with short timeout after giving the
3035 KILL command. Affected file lib/silcclient/command.c.
3037 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3038 case all found clients are already disconnected (WHOWAS would
3039 found them) in the server. Affected file silcd/command.c.
3041 * Update the last_receive (time of last data received) to be
3042 updated only when received private or channel message so that
3043 the idle time showed in WHOIS makes more sense.
3045 * Added boolean field `valid' in to the SilcClientEntry in the
3046 client library to indicate whether the entry is valid or not.
3047 This fixes the nickname change bug on channel when changing
3048 the nickname to be same than the old (like nick to Nick) the
3049 nickname formatter doesn't set the new nick anymore to Nick@host.
3050 Affected file lib/silcclient/idlist.[ch].
3052 * Now actually fixed the nickname changing on disconnection.
3053 Added new function silc_change_nick to the Irssi SILC Client.
3054 Affected file irssi/src/silc/core/client_ops.c,
3055 irssi/src/silc/core/silc-nicklist.[ch].
3057 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3059 * Check that the public key exists in the GETKEY command before
3060 trying to encode it. Affected file silcd/command.c.
3062 * Print some notifications on received public keys with GETKEY
3063 command in the Irssi SILC Client. Affected files are
3064 irssi/src/fe-common/silc/module-formats.[ch],
3065 irssi/src/silc/core/client_ops.c.
3067 * Use IDENTIFY command to resolve the server information in the
3068 GETKEY command instead of INFO command. Affected file
3069 lib/silcclient/command.c.
3071 * All command reply functions in the client library now calls
3072 the pending command reply callbacks even if an error has
3073 occurred. The server has done this a long time and now it was
3074 time to move the client library to this as well. Now all
3075 errors can be delivered back to the pending command reply
3076 callbacks if necessary. Affected files are
3077 lib/silcclient/command[_reply].[ch].
3079 * Change the nickname on disconnection back to the username
3080 because in reconnect the server will enforce it to it anyway.
3081 Affected file irssi/src/silc/core/silc-servers.c.
3083 * Fixed a config file parsing bug in the Irssi SILC client.
3084 Affected file irssi/src/silc/core/clientconfig.c.
3086 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * When printing the channel mode on JOIN, verify that the
3089 channel key and channel's HMAC are valid. Affected file
3090 irssi/src/silc/core/client_ops.c.
3092 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3094 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3095 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3096 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3098 * Removed channel key rekey task deleting from the function
3099 silc_server_save_channel_key. Affected file silcd/server.c.
3100 Added explicit timeout task context instead that is used to
3101 delete the task if we are registering a new task before the
3102 new task has elapsed.
3104 * When channel key rekey occurs the client library now saves
3105 the old channel key for a short period of time (10 seconds) and
3106 is able to use it in case some is still sending channel
3107 messages encrypted with the old key after the rekey. Affected
3108 file lib/silcclient/[idlist.h|client_channel.c].
3110 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3112 * Added check to the silc_server_new_id_real to not accept
3113 new ID if it is the sender's own ID. Affected file is
3114 silcd/packet_receive.c.
3116 * Assure that we do not announce ourself or the one we've
3117 sending our announcements when we're router and are announcing
3118 servers to our primary router. Affected file silcd/server.c.
3120 * Fixed silc_server_command_identify_check_client to assemble
3121 correct WHOIS packet. It send corrupted WHOIS packet and
3122 caused problem with router to router connections. Affected
3123 file silcd/command.c.
3125 Fixed also silc_server_command_whois_check the same way
3126 as for the IDENTIFY command.
3128 * Added new SilcIDListStatus to the server in the SilcIDListData
3129 structure. The status now includes the current status of
3130 the entry (like registered, resolved etc.). Affected file
3131 silcd/idlist.[ch]. Defined a bunch of different status types
3132 as well. This replaced the old boolean registered field as well.
3134 Added resolve_cmd_ident field to the SilcClientEntry structure
3135 too so that if the entry is for example being resolved so
3136 another command may attach to the same pending command reply
3137 without requiring to resolve the same entry again. This concept
3138 should optimize the WHOIS and the IDENTIFY resolving under
3139 heavy load by taking away unnecessary resolving for entries
3140 that are being resolved already.
3142 Added support for adding multiple pending commands for one
3143 command idenfier. Affected file silcd/command[_reply].[ch].
3145 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3146 before deleting the data. Otherwise the hash table will have
3147 freed data in comparison functions. Affected file is
3148 silcd/command_reply.c.
3150 * Fixed silc_idlist_replace_client_id to add the new entry to
3151 the cache with NULL nickname. Otherwise there will be invalid
3152 memory as the nickname after the nickname is freed. Affected
3153 file silcd/packet_receive.c.
3155 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3156 saved into wrong slots because the previous number of entries
3157 was not taken into account. Affected file silcd/idlist.c.
3158 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3160 * If we are router and we receive JOIN notify to a channel that
3161 does not have any users then notified client is marked as the
3162 channel founder, as it is it. The affected file is
3163 silcd/packet_receive.c
3165 * Added to the extended hash table API's table_del_*ext functions
3166 the destructor as argument too, so that the caller can decide
3167 which destructor to use or whether to use destructor at all.
3168 Affected file lib/silcutil/silchashtable.[ch].
3170 * Fixed ID Cache purging. It actually deleted the entries from
3171 the hash table after the data was freed. The hash table ended
3172 up comparing freed memory. The affected file is
3173 lib/silccore/silcidcache.c.
3175 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3177 * Fixed Irssi SILC client's KILL command's HELP syntax.
3179 * The USERS command now resolves the detailed user information
3180 if the userinfo field is missing. Affected file is
3181 lib/silcclient/command_reply.c.
3183 * Do not print error in silc_file_read if the read file does
3184 not exist. Just silently return NULL. Affected file is
3185 lib/silcutil/silcutil.c.
3187 * Fixed the silc_log_output to not wine about NULL filename
3188 and to not create some bogus " " filename. Affected file is
3189 lib/silcutil/silclog.c.
3191 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3193 * Fixed various printing bugs on the user interface in the
3194 Irssi SILC Client. Minor changes that were forgotten from
3197 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3199 * Fixed the configure.in.pre and the compilation and distribution
3200 environment to support the new autoconf 2.52. That version is
3201 now required to compile the CVS trunk.
3203 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3205 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3206 to generally parse user@fqdn format strings. Affected file
3207 lib/silcutil/silcutil.c.
3209 * Added nickname_format and nickname_force_format fields to the
3210 SilcClientParams structure. The first one defines the format
3211 for the nicknames that the library will enforce if the receives
3212 multiple same nicknames. The second one is boolean value and
3213 can be used to force the library to always enforce the format
3214 to the nicknames regardles whether there are multiple nicknames
3215 or not. This configurable formatting was employed to flexibly
3216 support accessing multiple nicknames from the user interface.
3217 The userinterface can now set the nicknames to what ever format
3218 they prefer. Affected file lib/silcclient/silcapi.h.
3220 Added function silc_client_nickname_format to the file
3221 lib/silcclient/idlist.c. It performs the nickname formatting.
3223 Added new field `hostname´ to the SilcClientEntry context.
3224 It holds the hostname of the client. Affected file is
3225 lib/silcclient/idlist.h.
3227 * Irssi SILC Client sets the nicknames in nick@hostn format.
3228 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3229 irssi/src/silc/core/silc-core.c.
3231 The WHOIS printing now also shows both the real nickname and
3232 the formatted nickname so that user knows how to access the
3233 user if there are multiple same nicknames cached. Affected
3234 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3235 printing formatting too to take the hostname now as a separate
3236 argument. The Affected file is
3237 irssi/src/fe-common/silc/modules-formats.[ch].
3239 * Changed the silc_client_get_clients_local to accept the formatted
3240 nickname as argument. It accepts the real nickname too but the
3241 formatted nickname can be used to find the true entry from
3242 multiple entries. Affected file lib/silcclient/silcapi.h and
3243 lib/silcclient/idlist.c.
3245 * Added nickname_format_parse field to the SilcClientParams.
3246 It is a callback function provided by the application to parse
3247 the nickname out of the formatted nickname string. The library
3248 calls it to get the nickname from the formatted string. Since
3249 the application generally knows better the format of the nickname
3250 string it parses it instead of the library, even though library
3251 encodes the formatted string. If the callback function is not
3252 provided then the library will use the string as is. The
3253 affected file is lib/silcclient/silcapi.h.
3255 * All the nickname strings passed to the client library in
3256 commands are now expected to be formatted nickname strings.
3257 If the command does not support the formatted nickname string
3258 it will assume that the sent string is the actual nickname.
3259 Affected file lib/silcclient/command.c.
3261 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3263 * Added public key authentication support to OPER and SILCOPER
3264 commands in the client library. Affected file is
3265 lib/silcclient/command.c.
3267 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3269 * Changed the get_auth_methdod client operation to be asynchronous.
3270 It can be async if the application resolves the authentication
3271 method from the server during the negotiation. Added new
3272 SilcGetAuthMeth completion callback that the application will
3273 call after resolving the authentication method.
3275 Added function silc_client_request_authentication_method that
3276 the application can use to resolve the authentication method
3277 from the server. Added also SilcConnectionAuthRequest callback
3278 that the library will call after the server has replied. The
3279 application can call this function if it does not know the
3280 current authentication method.
3282 Affected files are lib/silcclient/client.c and
3283 lib/silcclient/silcapi.h.
3285 * The Irssi SILC client now automatically resolves the authentication
3286 method incase any configuration information is not present (and
3287 currently there never is). The affected file is
3288 irssi/src/silc/core/client_ops.c.
3290 * Fixed public key authentication from the client library.
3291 Affected file lib/silcclient/protocol.c. Changed also the
3292 protocol specification about the public key authentication in
3293 the connection authentication protocol. The actual data to be
3294 signed is now computed with a hash function before signing.
3296 * Fixed the public key authentication from the server as well.
3297 Affected file silcd/protocol.c.
3299 * Removed the mlock()'s from the memory allocation routines.
3300 Affected file lib/silcutil/silcmemory.c. The ./configure does
3301 not check anymore for the mlock(). Affected file is
3304 * Fixed USERS command in server to allow the execution of the
3305 command for private and secret channels if the client sending
3306 the command is on the channel. Affected file silcd/command.c.
3308 * Fixed silc_client_get_clients_local to return the clients
3309 count correctly. It could return wrong value. Affected file
3310 lib/silcclient/idlist.c.
3312 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3314 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3315 types. The assembler optimizations seemed not to like 64-bit
3316 data types. The assmebler optimizations thus are now enabled
3317 also for BSD systems as opposed to only enable them for Linux.
3319 * Do not check for threads at all on BSD systems. Affected
3320 file configure.in.pre.
3322 * Removed -n and -h options from the Irssi SILC Client since
3323 they are not used in silc.
3325 * Fixed the prime generation to assure that the first digit
3326 of the generated random number is not zero since our conversion
3327 routines does not like number strings that starts with zero
3328 digit. If zero digit is seen the random number is regenerated.
3329 This caused some corrupted RSA keys when the zero first digit
3330 was met. Affected file lib/silcmath/silcprimegen.c.
3332 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3334 * Fixed WIN32 configuration in the ./configure script.
3335 Fixed to include xti.h on environments that has it.
3336 Patches by Carsten Ilchmann and andrew.
3338 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3340 * Changed the silc_id_create_client_id to be collision
3341 resistant. It is now assured that there cannot be created
3342 two same client ID's. I suspect that some weird bugs in
3343 the server were actually caused by duplicate Client IDs.
3344 Affected file silcd/serverid.[ch]. A router receiving
3345 new ID now also assures and informs the sending server
3346 if the ID caused collision.
3348 * Changed the silc_id_create_channel_id to also assure that
3349 there are no collisions.
3351 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3353 * Statement about ignoring the Mutual Authentication flag when
3354 performing rekey with PFS was a bit misleading. It is ignored
3355 if it was set in the initial negotiation, it cannot be even
3356 set in the rekey. Fixed in the ke-auth draft. Started the
3357 new versions of the protocol drafts in the doc/.
3359 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3361 * Fixed a bug in silc_client_command_identify_save when saving
3362 new channel information. The channel name was no duplicated
3363 and caused crash on exit. Affected file is
3364 lib/silcclient/command_reply.c.
3366 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3368 * Fixed the getkey command handling in the server. Send just
3369 empty OK reply to the sender if the key could not be fetched
3370 (but everything else was ok, like the key just was not available).
3371 Changed the public key parameter to optional in the protocol
3372 specs so that empty OK reply can be sent. Affected file
3375 Added a message to Irssi SILC client to tell to user if the
3376 server did not return a public key.
3378 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3380 * Fixed a channel key regeneration bug. It registered new
3381 timeout tasks exponentially until all system resources were
3382 used. Affected file silcd/server.c.
3384 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3386 * Added the SILC Document generator to the scripts/silcdoc.
3387 It can be used to generate the Toolkit Reference Manual out
3388 of the source tree. Internally it will also use the RoboDoc
3389 generator now imported in util/robodoc.
3391 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3393 * Added couple of return's in rekey protocol if error orccurred
3394 during the protocol. The execution must be terminated.
3395 Affected file silcd/protocol.c. Also, terminate the protocol
3396 always with timeout.
3398 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3400 * The client's Client ID was created initally from the wrong
3401 nickname (it could have been in format nick@host) in the
3402 silc_server_new_client. Affected file silcd/packet_receive.c
3404 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3406 * Added some SILC_LOG_ERROR's to various error conditions
3407 if client could not be added to ID cache. Affected files
3408 silcd/packet_receive.c and silcd/server.c.
3410 * When client's sock->user_data is freed, NULL also the
3411 client->router and client->connection pointers. Added check
3412 for these pointers being NULL to various places around the
3413 code. Affected file silcd/server.c.
3415 * Added client->data.registered == TRUE checks to various
3416 places around the code to assure that unregistered client's
3417 are not handled when it is not allowed. Affected file
3420 * Added `bool registered' fields to all
3421 silc_idlist_[server|client]_get_* routines to indicate whether
3422 the fetched client needs to be registered or not. Affected
3423 file silcd/idlist.[ch].
3425 * Add your own entry as registered to the ID cache in the
3426 server. Affected file server.c.
3428 * Fixed a bug in silc_server_new_server. The SilcServer was
3429 set as the new server's context instead of SilcServerEntry.
3430 This naturally caused some weird bugs.
3432 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3434 * Do not delete the channel rekey task when adding it
3435 for in silc_server_create_channel_key.
3437 * Changed the silc_server_create_channel_key to return
3438 TRUE or FALSE to indicate the success of the channel key
3441 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3443 * Fixed MSVC++ project files and added missing files to
3444 Makefiles under win32/.
3446 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3448 * Do not add TCP_NODELAY flag if the operating system
3449 does not have it defined. Affected files are
3450 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3452 * Fixed buffer overflow from Irssi SILC Client. Affected
3453 file irssi/src/fe-common/core/themes.c.
3455 * Fixed double free in client library in the file
3456 lib/silcclient/client.c when disconnecting from server.
3458 * Applied double free patch from cras to Irssi SILC client.
3459 Affected files irssi/src/core/[modules/expandos].c
3461 * Fixed the disconnection handling to Irssi SILC Client.
3462 The application must call silc_client_close_connection
3463 in ops->connect client operation in case of failure of
3464 the connection. Affected file is
3465 irssi/src/silc/core/client_ops.c.
3467 * Do not set sock->protocol to NULL in the function
3468 silc_client_close_connection after executing the protocol's
3469 final callback since the sock might not be valid anymore.
3470 Affected file lib/silcclient/client.c.
3472 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3474 * Do not enable SILC_THREADS if the linking with libpthread
3475 did not happen. Affected file configure.in.pre.
3477 * Added notion to protocol specification that server must
3478 verify the sent authentication payload with CMODE when
3479 setting the channel founder key. Implemented it to the
3480 server. Affected file silcd/command.c.
3482 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3484 * Added _EXTRA_DIST SILC distribution variable to the
3485 distributions file. It is used to conditionally add extra
3486 files or directories to the specific distribution. Affected
3487 files ./prepare, Makefile.am.pre and distributions.
3489 Removed the `_' from the start of the distribution names.
3492 * Added README.WIN32 for instructions to compile the Toolkit
3495 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3497 * Fixed a double free in disconnection in the server. Affected
3498 file is silcd/server.c.
3500 * Fixed the lib/silcske/groups.c to work now also with GMP
3501 MP library. The string conversion did not work when using
3502 specific base and the base is indicated in the string as well.
3504 * Created win32/ directory which now includes MSVC++ specific
3505 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3506 It will appear only in the toolkit distribution
3508 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3510 * Changed the key material distribution function in case when
3511 the hash output is too short. The data is now concatenated
3512 a bit differently than it used to. Made the change to the
3513 SKE protocol specification.
3515 * Added better GMP detection to configure.in.pre. A patch
3518 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3520 * Fixed a minor bug in SKE that might cause some problem on
3521 some platforms. Affected file lib/silcske/silcske.c.
3523 * Added the cookie checking for initiator in the SKE. It checks
3524 that the responder returns the sent cookie unmodified. The
3525 affected file is lib/silcske/silcske.c. Added new SKE
3526 error type INVALID_COOKIE that can be sent during the
3527 negotiation. Fixed some memory leaks as well.
3529 * Added the "invalid cookie" error message to Irssi SILC client's
3532 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3534 * Added `task_max' field to the SilcClientParams to indicate
3535 the maximum tasks the scheduler can handle. If set to zero,
3536 default values are used. Affected file lib/silcclient/silcapi.h.
3538 * Fixed memory leaks in silc_client_close_connection. Affected
3539 file lib/silcclient/client.c.
3541 * Added silc_client_del_client_entry to client library to free
3542 all memory of given client entry. Affected file is
3543 lib/silcclient/idlist.[ch].
3545 * Added new functions silc_client_del_channel and
3546 silc_client_del_server to delete channel and server entries.
3547 Affected file lib/silcclient/[silcapi.h/idlist.c].
3549 * Removed silc_client_del_client_by_id from silcapi.h.
3551 * Fixed the INFO command to return the server's own info
3552 correctly when querying by Server ID. Affected file is
3555 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3557 * Removed the non-blocking settings in WIN32 code in the
3558 silc_sock_[read/write] and added SleepEx instead. Affected
3559 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3560 of input data is now checked with FIONREAD and ioctlsocket.
3562 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * Call silc_schedule_task_del_by_context in the
3565 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3566 Affected file lib/silccore/silcprotocol.c.
3568 * Call silc_protocol_cancel for active protocols in the
3569 silc_server_close_connection if the funtion
3570 silc_server_free_sock_user_data has not been called.
3571 Affected file silcd/server.c.
3573 * Generic tasks cannot be deleted using the del_by_fd
3574 task deleting function since generic tasks does not match
3575 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3577 * Added a notion to SILCOPER help file that the SILCOPER works
3578 only on router server, not on normal server.
3580 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3582 * Added for WIN32 support for the new scheduler as well.
3583 Affected file lib/silcutil/win32/silcwin32schedule.c.
3585 * Fixed the SHA1 implementation to work on various platforms.
3587 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3589 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3590 API. It is part of the scheduler now. Everything else is
3591 as previously but some functions has changed their names.
3592 Checkout the lib/silcutil/silcschedule.h for the interface.
3593 Updated all applications to use the new interface. Affected
3594 files are lib/silcutil/silcschedule.[ch].
3596 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3598 * Found a bug in the SKE implementation. The HASH value,
3599 specified by the protocol, was not computed correctly. The
3600 public key of the responder was not added to the computation
3601 even though it is mandatory. Affected file lib/silcske/silcske.c.
3602 This unfortunately causes incompatibilities with older
3603 clients and servers.
3605 * Added WIN32 specific network init and uninit functions:
3606 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3607 the Winsock2. Affected file lib/silcutil/silcnet.h and
3608 lib/silcutil/win32/silcwin32net.c.
3610 * Set the socket always to nonblocking mode on WIN32 after
3611 reading data or writing data. Affected file is
3612 lib/silcutil/win32/silcwin32sockconn.c.
3614 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3616 * Fixed various compilation problems under WIN32. Affected
3617 files lib/silcutil/win32/silcwin32thread.c and
3618 lib/silcutil/win32/silcwin32schedule.c.
3620 * Removed all _internal.h #includes from public header
3621 files. Internal headers must never be included from
3624 Removed also the lib/silcske/payload_internal.h file.
3626 * All include files that may be needed (public and some others
3627 included by the public headers) by application developers are
3628 now copied to the ./includes directory. It does not copy any
3629 internal headers. Affected file Makefile.defines.pre and all
3630 Makefile.am's under lib/ and subdirs.
3632 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3634 * Do not change the ~/.silc directory's permissions automatically.
3635 Affected file irssi/src/silc/core/clientutil.c.
3637 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3639 * Do not cancel the protocol in silc_server_close_connection
3640 it might cause recursion. Now cancelled in the function
3641 silc_server_free_sock_user_data. Affected file silcd/server.c.
3643 * Fixed the silc_server_remove_clients_by_server to regenerate
3644 the channel keys correctly finally. Added also new function
3645 silc_server_remove_clients_channels to actually do it.
3646 Affected file silcd/server.c.
3648 * Fixed the silc_server_new_channel to not crash by giving
3649 wrong router to the new channel. Affected file is
3650 silcd/packet_receive.c.
3652 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3654 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3655 which is given as argument to the silc_client_alloc now.
3656 It can be used to configure the client and set various parameters
3657 that affect the function of the client.
3659 * The USERS command in server did not check whether the channel
3660 is private or secret. Affected file silcd/command.c.
3662 * Added new argument to the USERS command in protocol specification.
3663 The USERS command now can take the channel name as argument
3664 as well. Added support for this in client and server and
3665 updated the protocol specs.
3667 * Completed the GETKEY command in client. It can be now used
3668 to fetch also servers public key not only some clients.
3669 Affected files lib/silcclient/command[_reply].c.
3671 * Added silc_client_get_server to return server entry by the
3672 server name. Affected files lib/silcclient/silcapi.h and
3675 * Redefined the IDENTIFY command in protocol specification to be
3676 more generic. It now can be used to query information about
3677 any entity in the SILC Network, including clients, servers and
3678 channels. The query may be based either the entity's name
3679 or the ID. Added support for this in both client and server.
3681 Affected files silcd/command.c and lib/silcclient/command.c
3682 and command_reply.c.
3684 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3685 the _from_client and _from_server functions. Affected file
3688 * Added silc_client_get_channel_by_id_resolve to the file
3689 lib/silcclient/silcapi.h to resolve channel information by
3690 its ID. Added also silc_client_get_channel_by_id that
3691 does not resolve it from the server.
3693 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3695 * Added SilcServerEntry context into the client library
3696 to represent one server. The INFO command now allocates
3697 these to save the resolved server info. For now on the
3698 client library will also keep information about servers,
3699 connected and resolved with INFO.
3701 The INFO command now allocates the SilcServerEntry context
3702 and saves the server info there. The COMMAND_REPLY in
3703 the INFO now returns the parameters to application in
3704 same order as defined in the protocol specification.
3706 The entries are cached in the client->server_cache.
3708 * The INFO command is now issued after received the Client ID
3709 from the server. Affected file lib/silcclient/client.c.
3711 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3712 to the application as the mode changer might be server.
3713 It is guaranteed that NULL is not returned anymore to the
3714 application. Affected file lib/silcclient/client_notify.c.
3716 The ID Type is now also passed to the application so that
3717 it can check whether the returned entry is SilcClientEntry
3720 Added new function silc_client_get_server_by_id to return
3721 the server entry by ID. Affected files are the
3722 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3724 * Do not create the channel in the Irssi SILC Client when issuing
3725 the JOIN command but when received the sucessful JOIN command
3726 reply. Otherwise the channel might get created even though we
3727 could not join it. The Affected file is
3728 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3730 * Fixed a channel joining bug in router. The router must also
3731 check the channel modes, invite and ban lists etc. when serving
3732 the JOIN command sent by normal server. Affected file is
3733 silcd/command.c. The router now resolves the client's
3734 information from the server who sent the JOIN command if it
3735 does not know it, and processes the JOIN command only after
3738 * Changed the SilcCommandCb to take new argument; void *context2.
3739 Affected file lib/silccore/silccommand.h
3741 The second argument in the command callbacks in the server now
3742 includes the SilcServerCommandReplyContext if the command was
3743 called as pending command callback from the command reply.
3744 Otherwise it is NULL. When called as pending the status of the
3745 command reply will be checked and if it was erronous the
3746 error will be sent to the original sender of the command.
3747 This way the client always receives the error messages even
3748 though the server was actually the one who received the error
3749 when it resent the command to router, for example. Affected
3750 files silcd/command[_reply].[ch].
3752 * Fixed sending WHOWAS command's error message to client if
3753 the requested client could not be found. It was missing.
3756 * Changed the CMODE and CUMODE commands reply arguments in the
3757 protocol specification. The Channel ID is now sent in both
3758 of the commands to identify the channel. Implemented this
3759 new feature to the client and server. Affected files
3760 lib/silcclient/command_reply.c and silcd/command.c.
3762 * Made better checks for invite and ban lists in the JOIN
3763 command in server. Affected file silcd/command.c.
3765 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3767 * The server now performs the incoming host IP/DNS lookup
3768 using the silc_socket_host_lookup and thus does not block
3769 the server anymore. Affected file silcd/server.c.
3771 * Completed the multi-thread support for SILC Scheduler in
3772 the lib/silcutil/silcschedule.c.
3774 * Fixed the configure.in.pre to detect the pthread correctly
3777 * Fixed a deadlock in silc_task_queue_wakeup in the file
3778 lib/silcutil/silctask.c.
3780 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3782 * Added new function silc_schedule_wakeup that is used in
3783 multi-threaded environment to wakeup the main thread's
3784 schduler. It needs to be used when a thread adds a new task
3785 or removes a task from task queues. After waking up, the
3786 scheduler will detect the task queue changes. If threads
3787 support is not compiled in this function has no effect.
3788 Implemented the wakeup mechanism to both Unix and WIN32
3789 systems. Affected files are lib/silcutil/silcschedule.[ch],
3790 lib/silcutil/unix/silcunixschedule.c and the
3791 lib/silcutil/win32/silcwin32schedule.c.
3793 * Added new function silc_task_queue_wakeup to wakeup the
3794 scheduler by the specified task queue. Affected file
3795 lib/silcutil/silctask.[ch].
3797 * The silc_socket_host_lookup_start now wakes up the scheduler
3798 after adding the timeout task. Affected file is
3799 lib/silcutil/silcsockconn.c.
3801 * The silc_socket_host_lookup is synchronous now if the threads
3802 support is not compiled in. However, the callback is still
3803 called asyncronously through the scheduler, anyway. Affected
3804 file lib/silcutil/silcsockconn.c.
3806 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3808 * Added new function silc_socket_host_lookup to perform
3809 asynchronous IP and FQDN lookups for the socket connection.
3810 Affected files lib/silcutil/silcsockconn.[ch].
3812 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3814 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3815 that may or may not compile the mutex support in.
3817 Changed the silc_mutex_alloc interface. It allocates the
3818 mutex now to the sent pointer and returns TRUE or FALSE.
3820 Affected file lib/silcutil/silcmutex.h.
3822 * Wrote the SILC Task Queue interface to support multi-threads.
3823 Affected file lib/silcutil/silctask.[ch].
3825 * Wrote the SILC Scheduler to support multi-threads. Affected
3826 file lib/silcutil/silcschedule.c.
3828 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3830 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3831 in lib/silcutil/win32/.
3833 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3835 * Defined SILC Mutex API and SILC Thread API and implemented
3836 them for Unix. Affected files are
3837 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3838 lib/silcutil/unix/silcunixmutex.c and
3839 lib/silcutil/unix/silcunixthread.c.
3841 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3843 * Fixed the silc_server_remove_clients_by_server's channel
3844 key re-generation. The hash table handling was incorrect
3845 and would not work with many channels. Affected file is
3848 * Fixed some memory leaks around the server code.
3850 * Rewrote the silc_server_get_users_on_channel to support IPv6
3851 based Client ID's. Affected file silcd/server.c.
3853 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3854 specification. However, a separate document must be written
3855 to define the detailed signing procedure and the payload
3856 associated with the flag. Defined the flag to the
3857 lib/silccore/silcchannel.h as well.
3859 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3861 * Changed the dynamic tables to static size tables in the
3862 lib/silccrypt/silchmac.c.
3864 * Removed GCC dependencies from the code. A patch by cras.
3866 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3868 * Do not show the error "Error receiving packet bla bla"
3869 in server if it really was not an error (-2 means that reading
3870 is pending). Affected file silcd/server.c.
3872 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3874 * Fixed a possible crash in silc_server_remove_clients_by_server
3875 in silcd/server.c. Fixed there also some memory leaks.
3877 * Fixed the silc_idlist_replace_client_id. It could replace
3878 wrong key in the hash table. Affected file silcd/idlist.c.
3880 * Do not check whether there are global users on the channel
3881 if the channel->global_users is FALSE. Affected functions
3882 silc_server_remove_from_one_channel and
3883 silc_server_remove_from_channels in silcd/server.c. Also,
3884 do not check if the removed client is local as we can be
3885 sure that global client was not removed from the channel
3886 and checking for global users is not needed.
3888 * The silc_server_remove_clients_by_server now re-generates
3889 the channel keys correctly for those channels that had
3890 clients removed from them. Affected file silcd/server.c.
3892 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3894 * Found the reason of random crashes in the server. We weren't
3895 ignoring the SIGPIPE signal (which can be sent in write())
3896 and it crashed the server. Affected file silcd/silcd.c.
3898 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3900 * Assure that sock->user_data is not NULL in the function
3901 silc_server_packet_send in silcd/packet_send.c.
3903 * Disconnect the remote connection if it could not be added
3904 to any ID lists in the server. The affected file is
3907 * Check in silc_server_packet_send[_real/dest] that the
3908 socket is not disconnecting and ignore the data if it is.
3909 Affected file silcd/packet_send.c.
3911 * Define inline to __inline on native WIN32 compilation.
3912 Affected file includes/silcwin32.h.
3914 * Added some explicit type casts for inline code since MSVC
3915 require them. Affected files lib/silcutil/silcbuffer.h,
3916 lib/trq/silcdlist.h and lib/trq/silclist.h.
3918 * Print warning in log files from now on if the packet
3919 decryption fails. Affected file silcd/server.c.
3921 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3923 * Changed the `say' client operation's interface to accept
3924 new `type' argument to indicate the type of the message sent
3925 by the library. The application may filter the library's
3926 messages according the type. The affected file is the
3927 lib/silcclient/silcapi.h.
3929 * Added two new functions to lib/silcclient/silcapi.h:
3930 silc_client_del_client and silc_client_del_client_by_id.
3931 Affected file lib/silcclient/idlist.c.
3933 * Moved the clientincludes.h from includes/ to silc/ and
3934 serverincludes.h from includes/ to silcd/.
3936 * The modes for the CMODE and CUMODE are now passed as
3937 uint32 for application with COMMAND_REPLY. The affected
3938 file is lib/silcclient/command_reply.c.
3940 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3942 * /WHOIS without arguments shows client's own information.
3943 Affected file lib/silcclient/command.c.
3945 * Changed PING to not accept any arguments. The specs
3946 says that client can ping only the connected server so
3947 requiring an argument is not needed. Affected file is
3948 lib/silcclient/command.c.
3950 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3952 * Fixed a fatal bug in private message sending and reception
3953 encryption and decryption when using private message keys.
3954 The implementation was incorrect and did not follow the
3955 specification. It causd that some of the message were
3956 lost since it did not use the sending and receiving keys
3957 as the protocol suggests. This has been fixed and will cause
3958 incompatibilities with older clients when sending private
3959 message encrypted with private message keys. Affected files
3960 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3961 and various other in Irssi SILC Client.
3963 Added `responder' boolean argument to the functions
3964 silc_client_add_private_message_key[_ske] to indicate when
3965 the key is added as responder or initiator of the key
3968 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3970 * Removed the silc_ske_check_version function and created
3971 a SilcSKECheckVersion callback. Added also a function
3972 silc_ske_set_callbacks that is now used to set all SKE
3973 callbacks. The callback functions are not given to
3974 the SKE functions anymore, but this function is used to
3977 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3979 * Added `silc_version' argument to the silc_client_alloc
3980 to define the version of the application for the library.
3981 The library will use the version string to compare it
3982 against the remote host's (usually a server) version
3983 string. Affected file lib/silcclient/silcapi.h
3985 * Added the KE protocol context to Key Agreement context
3986 in client library so that we can abort the SKE if it
3987 is in process when we get timeout. Affected file is
3988 lib/silcclient/client_keyagr.c.
3990 * Do not resolve the client ID forever if it returns in the
3991 first time that such client does not exist. This was done
3992 for example with private message. Affected file is
3993 lib/silcclient/client_prvmsg.c.
3995 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3997 * Do not add regex.h for WIN32. The affected file
3998 includes/silcincludes.h.
4000 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4001 not work yet 100%. It generates the DLL's automatically
4002 when compiling with --with-win32 under cygwin.
4004 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4006 * lib/contrib/regex.c is not compiled on WIN32.
4008 * Added silc_net_get_socket_opt function to the
4009 lib/silcutil/silcnet.h.
4011 * Added includes/silcwin32.h for WIN32 specific includes
4014 * Do not use ptime structure or any of the posix process
4015 functions on WIN32 in lib/silccrypt/silrng.c.
4017 * Added silc_gettimeofday to provide generic function
4018 for struct timeval on all platforms. Added the function
4019 to lib/silcutil/silcutil.h.
4021 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4023 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4024 library as they clearly belong there. As a plus side we
4025 can make the actual socket connection routines platform
4028 Added also new generic function silc_socket_read and
4029 silc_socket_write (that used to be silc_packet_[read/write].
4030 The implementation of these are platform specific.
4032 * Added WIN32 specific routines of silc_socket_[read/write]
4033 to lib/silcutil/win32/silcwin32sockconn.c.
4035 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4037 * Added preliminary support for native WIN32 compilation under
4038 cygwin (using the -mno-cygwin option for GCC) to the
4039 ./configure.in.pre. The --with-win32 now prepares the
4040 compilation for native WIN32.
4042 * Rewrote the SILC Scheduler interface in the file
4043 lib/silcutil/silcschedule.h. The scheduler is now context
4044 based and does not have anymore any global static scheduler.
4045 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4046 and created lib/silcutil/win32 directory for WIN32 based
4049 * Added Unix specific network routines to the
4050 lib/silcutil/unix/silcunixnet.c and the old
4051 lib/silcutil/silcnet.c includes now only generic routines.
4053 Added WIN32 specific network routines to the
4054 lib/silcutil/win32/silcwin32net.c.
4056 * Added Unix specific utility functions from the
4057 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4059 * Added WIN32 SILC Scheduler to the file
4060 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4063 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4065 * Do not handle JOIN notify in the server if the target client
4066 is not registered (idata->registered == FALSE). The affected
4067 file is silcd/packet_receive.c.
4069 * Update the nickrec->founder in event_cumode in the Irssi SILC
4070 client. Affected file irssi/src/silc/core/silc-channels.c.
4072 * Fixed the CUMODE_CHANGE notify handling in the server when
4073 server and router are announcing their clients on channels.
4074 Now the mode changes are saved and notified correctly. The
4075 affected file is /silcd/packet_receive.c.
4077 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4078 They really did not replace the cache entry in the ID Cache.
4079 Now they do that. Affected file silcd/idlist.c.
4081 * Fixed the KICK notify handling in the Irssi SILC client to
4082 update the channel records so that the kicked client does not
4083 appear to be on the channel. The affected file is
4084 irssi/src/silc/core/silc-channels.c.
4086 * Always update the conn->current_channel when executing command
4087 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4089 * Fixed the KILL notify handling in Irssi SILC client to remove
4090 the killed client on all channels.
4092 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Fixed the silc_parse_command_line to remove extra spaces
4095 from the start and end of the arguments. Affected file is
4096 lib/silcutil/silcutil.c.
4098 * Cancel and free any active protocol in the function
4099 silc_server_close_connection. Affected file silcd/server.c.
4101 * Cancel and free any active protocol in the function
4102 silc_client_close_connction. Affected file is
4103 lib/silcclient/client.c.
4105 * Do not execute the KILL command for clients that are in
4106 history (ie. they are not in the network). Affected file is
4109 * Fixed KILL notify handling, client does not crash anymore.
4110 Affected file irssi/src/silc/core/silc-channels.c.
4112 * Reduced the default packet buffer size from 2048 to 1024 in
4113 lib/silccore/silcpacket.c.
4115 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4116 counter to the SKE context that is incresed when the SKE library
4117 performs async operation outside the library. If the outside
4118 process frees the SKE context and FREED status will be set
4119 and the library will detect after the sync operation that the
4120 libary is freed. The affected files are
4121 lib/silcske/silcske[_status].[ch].
4123 * Resolve the client entry information in the function
4124 silc_client_channel_message to assure that NULL pointer is not
4125 passed as client entry to the application. */
4127 * Fixed the task timeout calculation to assure that there is
4128 never negative timeouts. The affected file is
4129 lib/silcutil/silcschedule.c.
4131 * Fixed the channel user mode notification sending in server.
4132 It was sent point-to-point to the router (or to server by router)
4133 but it needs to be destined to a channel. The routines now
4134 supports sending the channel user mode notifys to the channels
4135 when announcing clients and channels. Affected files are
4136 silcd/server.c and silcd/packet_receive.c.
4138 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4139 It did not actually replace the old channel entry in the cache.
4140 Affected file lib/silcclient/client_notify.c.
4142 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4144 * Fixed a possible crash in silc_packet_send_prepare. It now
4145 assures always that there is enough space in the buffer and
4146 at the tail area of the buffer (for MAC).
4148 Fixed the inbound buffer reallocation in silc_packet_read.
4149 It was old code and did not handle the reallocation correctly.
4152 The affected file is lib/silccore/silcpacket.c.
4154 * Fixed buffer overflow in silc_parse_nickname in the file
4155 lib/silcutil/silcutil.c.
4157 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * make install generates new server keys only if there is not
4162 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4165 Added check that if the NOREPLY is set then we will not send
4166 the away message. This avoids infinite loop of away messages
4167 if both clients are away. The affected file is
4168 lib/silcclient/client_prvmsg.c.
4170 * Fixed client crash if /NICK was given without arguments.
4171 Affected file lib/silcclient/command.c.
4173 * Server does not send the invite list in INVITE command back
4174 to the client if the list was not altered. Added this notion
4175 to the protocol spec as well. Affected file silcd/command.c.
4177 Fixed possible crash in INVITE command by checking the
4178 value of silc_server_get_client_route command.
4180 * Fixed the INVITE notify type handling. The arguments are now
4181 taken in correct order and client does not crash. The affected
4182 file is irssi/src/silc/core/silc-channels.c.
4184 Removed the "Inviting xxx to channel" message from the
4185 client library away and let the application handle it.
4186 Affected file lib/silcclient/command.c. Added that message
4187 to Irssi SILC client's message formats.
4189 * Fixed CMODE command crash in client. It now checks the
4190 amount of arguments correctly and does not crash. The affected
4191 file is lib/silcclient/command.c.
4193 * Do not create new channel automatically in silc_channels_join
4194 but check whether the channel by that name already exists.
4195 Affected file irssi/silc/core/silc-channels.c.
4197 * Do not send the SERVER_SIGNOFF to router if the disconnected
4198 entity was the router. Affected file silcd/server.c.
4200 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4201 SILC client as it was missing from there.
4203 Added the handling of the KICK notify to the Irssi SILC client
4204 as it was missing. Added "you have been kicked" message to
4205 Irssi SILC client's message modules formats.
4207 Added the handing of the KILL notify to the Irssi SILC client
4208 as it was missing. Added the kill message module formats
4211 The affected file is irssi/src/silc/core/silc-channels.c.
4213 * The router did not save the channel mode the server announced.
4214 Affected file silcd/packet_receive.c.
4216 * Fixed a possible crash in INFO command in server. If the
4217 server did not provide the server info it crashed. Affected
4218 file silcd/command.c.
4220 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Fixed the GETKEY command in the server to check also the
4223 global list. Otherwise the GETKEY would not work correctly
4224 in normal SILC server. Affected file silcd/command.c.
4226 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4228 * Fixed GETKEY crash, it crashed if the command did not succseed.
4230 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4233 is now real and not just an macro interface to GMP.
4235 Removed the entire GMP from the source tree and imported new
4236 NSS MPI library instead. Reason for removing GMP is that it is
4237 extremely large and compiles extremely slow. The NSS MPI
4238 is only a few files and compiles in less than 10 seconds.
4239 The speed is also about the same as GMP. The MPI is imported
4240 to lib/silcmath/mpi.
4242 If the system has GMP installed we will still use the GMP.
4243 If it is not then the NSS MPI will be compiled.
4245 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Merged a long nickname (127 characters long) crash bugfix from
4248 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4250 * Merged a freed memory reference bugfix from Irssi CVS tree.
4251 Affected file irssi/src/core/commands.c.
4253 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4255 * Added the server's public key sving and verification to the
4256 server when performing the SKE. This was missing and the
4257 remote server's (or router's) public key was accepted without
4258 checking whether we have it previously or trust it at all.
4259 Affected file silcd/protocol.c.
4261 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Check in the silc_server_timeout_remote if protocol is active
4264 and make sure that the protocol's final callback is called so
4265 that all memory if freed. Affected file silcd/server.c.
4267 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * silc_server_whois_send_reply crashed the server if the nickname
4270 was 127 characters long. Affected file silcd/command.c.
4272 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4274 * Added sanity check to the silc_server_new_client. If the hostname
4275 is provided inside username then check that the provided hostname
4276 really is the same as the resolved one. If the hostname was not
4277 resolved then check it from the public key. Affected file is
4278 silcd/packet_receive.c.
4280 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4281 if the server disconnected us and the connection is not valid
4282 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4284 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4285 the library to the lib/silcutil/silcutil.[ch].
4287 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Close log file after open. Affected file
4290 lib/silcutil/silclog.c.
4292 * Check whether sock == NULL in silc_client_send_packet and return
4293 if it is. Affected file lib/silcclient/silcclient.c.
4295 * Check rec->entry == NULL in the Irssi SILC Client before
4296 sending the channel message. Affecte file is
4297 irssi/src/silc/core/silc-servers.c.
4299 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Merged a splitted window bugfix from Irssi CVS tree. The
4302 affected file is irssi/src/fe-text/textbuffer-view.c.
4304 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4305 It did not print nickname.
4307 * Improved the distributions system a bit.
4309 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4312 irssi/src/fe-text/gui-window.c.
4314 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4315 to in-active server. The affected file is
4316 irssi/src/silc/core/client_ops.c.
4318 * Resolve the client in USERS command reply if the entry does
4319 not have username resolved. The affected file is
4320 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4321 command to WHOIS command to really resolve stuff. The USERS
4322 is not used any more in any critical section so WHOIS can
4323 be used even though it might be slower than IDENTIFY.
4325 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4328 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Changed the protocol API a bit more consistent in the
4331 lib/silccore/silcprotocol.[ch].
4333 * Changed the following headers to ROBODoc format:
4335 lib/silccore/silcpayload.h
4336 lib/silccore/silcprotocol.h
4337 lib/silccore/silcsockconn.h
4339 All core library headers are now formatted.
4341 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Fixed a bug in Irssi SILC client; do not show that you are
4344 server/router operator if you really are not. Affected file is
4345 irssi/src/silc/core/client_ops.c.
4347 * Renamed silc_command_free_payload to silc_command_payload_free.
4348 Affected file lib/silccore/silccommand.h
4350 * Added silcmath.h to include the prototoypes of various routines
4351 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4354 * Changed the following headers to ROBODoc format:
4356 lib/silccore/silcchannel.h
4357 lib/silccore/silccommand.h
4358 lib/silccore/silcid.h
4359 lib/silccore/silcidcache.h
4360 lib/silccore/silcmode.h
4361 lib/silccore/silcnotify.h
4362 lib/silccore/silcpacket.h
4363 lib/silcmath/silcmath.h
4365 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Added checking to the server code not to start the server if
4368 ciphers and stuff are not configured properly. Affected files
4369 silcd/serverconfig.[h] and silcd/server.c.
4371 * Changed the layout of the header files of the public interfaces
4372 in the SILC libraries. The new layout supports ROBODoc
4373 documentation tool (and some others) so that it is easy to create
4374 a library reference manual. All the other headers and source
4375 code must still follow the CodingStyle document. Also source
4376 code must not include these ROBODoc stuffs, only the headers.
4377 Furthermore, all public interface headers must now be named
4378 by using `silc' prefix, example: silcapi.h, silccipher.h.
4379 Some files were renamed due to this. All the other headers
4380 must not be used as public interfaces. I will update the
4381 CodingStyle document later. Changed following headers, so far:
4383 lib/silcclient/silcapi.h
4384 lib/silccore/silcauth.h
4385 lib/silccore/silcprivate.h
4386 lib/silccrypt/silcdh.h
4388 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Removed silc_client_packet_send_flush from the client library
4393 as it is not needed. Affected file lib/silcclient/client.[ch].
4395 * Added printing of message of unresolved authentication method
4396 to the Irssi SILC client. Added it to the module formats.
4397 Removed the same message from the client library.
4399 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Added new distribution feature, DISTLABEL. Every distribution
4402 can define own preprocessor label that can be used in the
4403 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4404 file distributions, acconfig.h.pre and prepare.
4406 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Added Makefile.defines_int to include the actual definitions
4409 for Makefile.defines.in. Tested the new distribution system,
4410 created distributions and tested installation.
4412 * Added AWAY message printing to the Irssi SILC client. Added
4413 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4415 * Added SCONNECT command to call the SILC's CONNECT command.
4416 Cannot use CONNECT directly since Irssi uses that internally.
4417 Affected file irssi/src/silc/core/silc-servers.c.
4419 Added ACTION local command. It is same as ME command but takes
4420 the channel as mandatory argument.
4422 Rewrote some of the Irssi's help files to suite for SILC
4425 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Added Makefile.defines[.in] that should for now on be included
4428 in all Makefile.am file in the source tree. That file includes
4429 all common compilation definitions for SILC source tree.
4431 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Minor changes to the ./prepare script to change the package
4434 name according the distribution name to the configure.in.
4436 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Created new distribution system. Added file `distributions'
4439 that defines all the distributions that can be created out of
4440 the SILC source tree. The ./prepare script now reads that
4441 file to determine how to prepare the distributions. The
4442 first argument to the ./prepare is the name of the distribution
4443 and second is the version of the distribution. If given
4444 without arguments it creates the default (toolkit) distribution
4445 with the default version (defined in ./prepare).
4447 All Makefile.am files that are subject to the distributions
4448 are now named as Makefile.am.pre. These are ./Makefile.am
4449 and lib/Makefile.am. Others may be changed later.
4451 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Added invite list, ban list, some key management and connection
4454 error message printing to module formats in the Irssi SILC client.
4456 * Added new silc_client_set_away_message to set the away message
4457 that is back to the person who sent private message. The
4458 affected file lib/silcclient/silcapi.h and the
4459 lib/silcclient/client_prvmsg.c.
4461 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Fixed the private message sending in the Irssi SILC client,
4464 added local command KEY to the Irssi SILC client.
4466 Added key management and key agreement message formats to the
4467 irssi/src/fe-common/silc/module-formats.[ch].
4469 Added USERS (alias WHO) printing, server/router operator
4470 indication and LIST command printing to the module formats.
4472 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Fixed channel joining notify handling, cumode notify handling
4475 from Irssi SILC client.
4477 * Added SILC specific module-formats to the Irssi SILC client so
4478 that SILC specific message hilighting, colors etc is possible.
4479 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4481 Added channel mode, channel user mode, actions, notices,
4482 whois and whowas printing to the the module-formats.c.
4484 * Fixed a bug in channel deletion in the server. The channel
4485 is not left to the cache even if the channel founder auth mode
4486 is set when there are no users anymore on the channel. Affected
4487 file silcd/server.c.
4489 * The silc_net_localhost now resolves the entire hostname including
4490 the domain name. Affected file lib/silcutil/silcnet.c.
4492 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Changed the ask_passphrase client operation to be ascynchronous.
4495 It has now a completion callback and a context that the
4496 application must call after it has got the passphrase from
4497 the user. Affected files lib/silcclient/silcapi.h,
4498 lib/silcclient/protocol.c, lib/silcclient/command.c and
4501 Added SilcAskPassphrase callback that the application calls
4502 to deliver the passphrase to the library.
4504 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4505 The public key verification and especially a certificate
4506 verification is asynchronous procedure.
4508 Added new SILC_SKE_STATUS_PENDING status to indicate the
4509 request is pending and a callback will be called to finalize
4512 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4513 indicate that remote end did not send its public key (or
4514 certificate), even though we require it. Added check for this
4515 condition in the SKE. This was a security bug, now fixed.
4517 Defined new SilcSKEVerifyCbCompletion callback that is called
4518 when the verification process is completed.
4520 The affected files lib/silcske/silcske_status.h and
4521 lib/silcske/silcske.[ch].
4523 * Changed the verify_public_key client operation to be async
4524 as well. Defined SilcVerifyPublicKey callback that is used to
4525 indicate the success of the public key verification process.
4527 Changed the server and client to use the new async client
4530 * Changed the Irssi SILC client's internal scheduler to be called
4531 twice as many times as it used to be. As a result the client
4532 should be a bit faster now. Affected file is
4533 irssi/src/silc/core/silc-core.c.
4535 * Added support to Irssi SILC client of asynchronous public key
4536 verification and passphrase inquiry. Affected file is
4537 irssi/src/silc/core/silc-core.c.
4539 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Do not say "You have left channel %s" in client library.
4542 Moved it to the application. Affected files are
4543 lib/silcclient/command.c and silc/client_ops.c.
4545 * Fixed silc_client_get_clients. Command context was not
4546 duplicated and was freed memory in the callback. Affected
4547 file lib/silcclient/idlist.c.
4549 * Do not say "you are now talking..." on JOIN command in the
4550 client library. The appliation must handle it.
4552 * Do not say ".. changed topic to" in command reply in the
4553 client libary. The application must handle it.
4555 * Fixed TOPIC command sending in the client library.
4557 * Fixed a memory leak in silc_client_command_free in the file
4558 lib/silcclient/command.c.
4560 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Imported a modified version of Irssi client to the source tree.
4563 The Irssi will be used to create a new client called
4564 Irssi SILC. Imported to irssi/.
4566 Added silc_core_init_finish function to the Irssi. Affected
4567 file irssi/configure.in.
4569 A lot changes in the Makefile.ams around the irssi tree.
4571 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Do not rehash if the new size is same as the old size of the
4574 hash table, in the silc_hash_table_rehash*. The affected file
4575 lib/silcutil/silchashtable.c.
4577 * Replaced hash_table_del_by_context calls from the server
4578 (when channel->user_list and client->channels) to the
4579 hash_table_del as it is sufficient and faster.
4581 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Added silc_hash_table_list, silc_hash_table_get and the
4584 SilcHashTableList structure to provide an alternative way to
4585 traverse the hash table. The affected files are
4586 lib/silcutil/silchashtable.[ch].
4588 * Changed the server's idlist routines to use the hash table
4589 routines to optimize the code.
4591 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Replaced the client entry's `channel' list and channel entry's
4594 `user_list' list to hash tables for optimized lookup. Changed
4595 the code to use the hash table interface around the code.
4596 Affected file lib/silcd/idlist.[ch].
4598 * Added `auto_rehash' boolean argument to the function
4599 silc_hash_table_alloc to indicate whether the hash table should
4600 auto-rehash when it thinks is appropriate time. It will
4601 increase the hash table size if the there is twice as much
4602 entries in the table than the size of the table, and will
4603 decrease the size if there are twice as less entries than
4604 the size of the table.
4606 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4610 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * silc_idcache_purge_by_context deletes the entry now by context
4613 as it is supposed to do. Affected file lib/silccore/idcache.c.
4615 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4616 client is not anymore valid (WHOWAS givens the info) and not
4617 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4619 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Removed the `data' and `data_len' arguments from the ID Cache
4622 interfaces and added `name' argument. ID Cache does not handle
4623 anymore the binary data only a names associated with given ID.
4625 * When hashing a Client ID with silc_hash_id the entire ID is
4626 not hashed anymore, instead only the hash of the Client ID is
4627 hashed. This way we can access the Client ID from the cache
4628 with Client ID but with the hash of the ID (which is a hash of
4629 the nickname) as well without any difference in performance.
4631 Added also silc_idcache_find_by_id_one_ext to do one on one
4632 searching when we have the actual ID. Added also function
4633 silc_hash_client_id_compare. The affected files are
4634 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4636 * When hashing the name associated with a ID it is always done
4637 in lowercase. This way we can access the cache without worrying
4638 about case-sensitivity, even though, for example nicknames are
4641 * Fixed a bug in server with channel message sending. It put
4642 wrong ID type as destination ID. The affected file
4643 silcd/packet_send.c.
4645 * silc_idcache_del_by_context now deletes from all hash tables
4646 by context. Affected file lib/silccore/idcache.c.
4648 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Changed the client library to use the new ID Cache interface.
4651 Changes around the source tree.
4653 * Added silc_hash_table_rehash_ext to rehash with specific
4654 hash function. Affected file lib/silcutil/silchashtable.[ch].
4656 * Added silc_hash_string_compare to compare two strings in the
4657 hash table. Affected file lib/silcutil/silcutil.[ch].
4659 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Added new function silc_idcache_del_by_context into the
4662 lib/silccore/idcache.[ch].
4664 * Changed the server's ID list routines to use the new ID Cache
4665 interface. Changes around the source tree.
4667 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Added silc_hash_table_del[_by_context]_ext functions in to the
4670 lib/silcutil/silchashtable.[ch].
4672 Removed silc_hash_table_find_all* routines and added new
4673 silc_hash_table_find_foreach to replace them.
4675 Added silc_hash_table_replace_ext function as extended
4676 replacing function. Separated the simple hash table interface
4677 from the extended hash table interface in the file
4678 lib/silcutil/silchashtable.h.
4680 * Fixed minor bugs and changed it to use some of the new
4681 hash table functions in lib/silccore/idcache.c
4683 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * Added new function silc_hash_table_find_all to return all keys
4686 in the hash table by the specified key. As the hash table is
4687 collision resistant it also makes it possible to have several
4688 duplicate keys in the hash table. This function may be used to
4689 find all of the keys from the hash.
4691 Added user_context arguments to the SilcHashFunction,
4692 SilcHashCompare and SilcHashDestructor to deliver user specified
4695 Added new fuctions silc_hash_table_find[_all]_ext to do
4696 extended lookup with specified hash and compare functions and
4697 specified user contexts.
4699 Added new function silc_hash_table_add_ext to add the key
4700 with specified hash function and user context.
4702 Added new function silc_hash_table_foreach to traverse all
4703 entrys in the hash table. Added SilcHashForeach callback
4706 Added new function silc_hash_table_del_by_context to delete
4707 the entry only if the context associated with the key matches.
4709 Affected files are lib/silcutil/silchashtable.[ch].
4711 * Removed silc_hash_[server/client/channel]_id and added just
4712 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4713 silc_hash_id_compare to compare two ID's using as the hash table
4714 comparison function. Added also silc_hash_data to hash
4715 binary data and silc_hash_data_compare to compare it.
4717 * Removed silc_idlist_find_client_by_hash as it is not needed
4718 anymore. Affected file silcd/idlist.[ch].
4720 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4721 to use internally the SilcHashTable. The new ID Cache is a lot
4722 faster than the old one. Some of the ID Cache interface was also
4723 rewritten and obsolete and stupid functions were removed.
4725 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * Added entry_count field to the SilcHashTable to keep the number
4728 of the entries in the table. Implemented the function
4729 silc_hash_table_rehash. Added new function
4730 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4732 Fixed a minor bug in silc_hash_table_free.
4734 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4735 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4736 into the lib/silcutil/silcutil.[ch].
4738 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Implemented a collision resistant hash table into the
4741 lib/silcutil/silchashtable[ch]. See the header and the source
4742 for the SilcHashTable API.
4744 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * Merged dotconf version 1.0.2 into lib/dotconf.
4748 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Do not compile anything in lib/silcsim/* if the SIM support
4751 is not enabled. The tree should now compile without problems
4754 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Compiled the SILC under cygwin. Compiled and tested briefly
4757 without problems. More tests needed. The SIMs didn't compile
4760 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4762 * Fixed possible crash in silc_get_username in the
4763 lib/silcutil/silcutil.c.
4765 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Fixed a va_arg in silc/client_ops.c.
4769 * Oops, RC5 routines were named AES and caused some problems
4770 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4772 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Added new SilcIDIP structure into the lib/silccore/id.h and
4775 replaced the old `ip' fields from all SILC ID's to that type.
4776 This is a step towards IPv6 support.
4778 The silc_id_get_len takes now the ID as an extra argument.
4779 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4780 both IPv4 and IPv6 based ID's.
4782 The affected files are lib/silccore/id.[ch] and other files
4783 around the tree using these routines.
4785 * Removed the ID length arguments in server from various
4786 silc_server_send_notify_* routines -> they are not needed
4789 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Fixed memory leak in silc_encode_pem_file in the file
4792 lib/silcutil/silcutil.c.
4794 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Check minor version as well in the SKE. Affected files are
4797 silcd/protocol.c and lib/silcclient/protocol.c.
4799 * Added --identifier option to the server so that an identifier
4800 can be when creating the public key for the server. Affected
4801 file is silcd/silcd.c.
4803 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4804 lib/silccrypt/silcpkcs.c.
4806 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * Register default ciphers and stuff when using -C option with
4809 the server. Affected file sildc/silcd.c.
4811 * Put back the servers public key filename format, it is better
4812 than the new one. For now, the client keys are saved with the
4813 new filename format. The affected file silc/client_ops.c.
4815 * Implemented the Cipher API for the rest of the ciphers that
4816 did not implement it or implemented it the wrong way.
4818 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Register default ciphers and stuff when using the -S option
4821 in the client. Affected file silc/silc.c. Same also when
4822 creating new key pair with -C option.
4824 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Fixed the silc_verify_public_key client operation function to
4827 save the public keys differently. The fingerprint is now
4828 used as filename and not the hostname. This way also the
4829 client keys are saved uniquely and not with hostnames. The
4830 affected file is silc/client_ops.c.
4832 * Trimmed the silc_hash_fingerprint function to remove extra
4833 whitespaces from the end of the fingerprint. The affected
4834 file is lib/silccrypt/silchash.c.
4838 * Added silc_cipher_register_default function to register all
4839 default ciphers. It can be used when configuration files
4840 does not exist and the application does not want any specific
4841 ciphers in any specific order.
4843 The SilcDList is now used as silc_cipher_list dynamically
4844 allocated cipher list. Removed the static list all together
4845 and now all ciphers must be allocated to the dynamic list.
4846 The silc_cipher_alloc routine was changed to check only the
4849 All silc_cipher_* routines that used to return int returns
4852 The affected files lib/silccrypt/silccrypt.[ch].
4854 * The same thing was done to silc_hash_* as for silc_cipher_*
4855 routines. Affected files lib/silccrypt/silchash.[ch].
4857 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4858 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4859 Added also silc_pkcs_[un]register[_default] functions.
4860 Removed the data_context from the PKCS API.
4862 * Added silc_hmac_register_default function to register default
4863 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4864 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4865 to unregister all hmacs at once.
4867 * Register the default ciphers, hash functions, PKCSs and HMACs
4868 if client's configuration file does not exist. The affected
4871 * The client did not load the hash functions from the SIM
4872 modules at all. Added support for this. Affected file is
4873 silc/clientconfig.c.
4875 * When decoding public key with silc_pkcs_public_key_decode, check
4876 the supported algorithm only if PKCS are registered. Affected
4877 file lib/silccrypt/silcpkcs.c. The same was done with the
4878 silc_pkcs_private_key_decode.
4880 * Fixed the SILC List routines to keep the list always in order.
4881 It used to change the list's order when traversing the list but
4882 not it preserves the order. Affected file lib/trq/silclist.h.
4884 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Added the client library to use the SilcSocketConnection's
4887 reference counter (by silc_socket_dup) to prevent the bug that
4888 the socket object may be freed underneath async operation.
4890 * The name resolv library checking fixes in the configure.in.pre.
4893 * Created new version of the protocol drafts for future
4894 development. The -03 drafts are the ones that will be changed
4895 in the trunk now and the -02 will remain as they are.
4897 * Send list of CUMODE notifys to the router when announcing
4898 the channel users to the router. Affected file silcd/server.c.
4899 If the router receiving channel founder CUMODE for a channel
4900 that already has channel founder it will send CUMODE notify
4901 to the sender to remove the channel founder rights from the
4902 announced client. Affected file silcd/packet_receive.c.
4904 * The CUMODE notify may now use Server ID as well as the entity
4905 who changes the mode. Updated protocool specs.
4907 * Updated INSTALL and README files.
4909 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * New web pages in the http://silc.pspt.fi. The pages was
4916 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4918 * Implemented the [DenyConnectin] config section in the server.
4919 Added silc_server_config_denied_conn to check whether incoming
4920 connection is denied. Affected file silcd/serverconfig.[ch].
4922 * Do not check the ports when checking the incoming configuration
4923 data if the port is 0, meaning any. Affected file is
4924 silcd/serverconfig.c.
4926 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Fixed buffer overflow in silc_string_compare in the file
4929 lib/silcutil/silcutil.c.
4931 * Fixed double free in silc_server_command_leave in the file
4934 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4936 * Fixed the version checking in the server. Affected file is
4939 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * Fixed the configuration data fetching when accepting new
4942 connections in the server. Affected file silcd/server.c.
4944 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4946 * Added `sender_entry' argument to the function
4947 silc_server_packet_relay_to_channel so that we can check
4948 whether some destination actually belongs to the same route
4949 the sender belongs (ie, we must not resend the packet to the
4950 sender). Affected file silcd/packet_send.[ch].
4952 * Added `servername' field to the SilcClientEntry in the server
4953 to hold the name of the server where client is from. Affected
4954 file is silcd/idlist.h.
4956 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Moved the channel message encrypting in the router betwen
4959 router connections from silc_server_channel_message to the
4960 silc_server_packet_relay_to_channel since we want to check
4961 whether we have anybody channel before encrypting anything.
4962 Affected files silcd/packet_[receive/send].c.
4964 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Fixed the [AdminConnection] server config section to support
4967 multiple entries. Affected file silcd/serverconfig.c.
4969 * Added support into the server to check the validity of the
4970 incoming connection before executing any KE or authentication
4973 * The connection configuration is now saved to the KE and
4974 connection auth protocol contexts and not fetched anymore in
4975 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4977 * The local hosts listenning address and port is also resolved
4978 now when starting the server. We want to have the socket object
4979 to include the real address and port for the listener. Added
4980 new function silc_net_check_local_by_sock into the files
4981 lib/silcutil/silcnet.[ch].
4983 * Fixed a broadcast bug in server -> do not broadcast if we
4986 * Fixed a routing bug. Do not route broadcast packets ever.
4987 Broadcast packets must be processed always and not routed since
4988 they may be destined to some other host than yourself and thus
4989 would get routed without no good reason. Affected file is
4992 * Added function silc_server_config_is_primary_route to check
4993 whether primary router connection has been configured (a router
4994 configuration that we are initiating). If there is not, we
4995 will assume that there is only two routers in the SILC network
4996 and we will use the incoming router connection as our primary
4997 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4999 * Changed the order of the broadcasting. Broadcast _after_ the
5000 packet has been processed not before. Affected file is
5003 * Fixed a [ClientConnection] parsing bug. The port was never
5004 parsed correctly thus resulting to port 0. Affected file
5005 silcd/serverconfig.c.
5007 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5008 argument and did not set the broadcast packet flag. Affected
5009 file silcd/packet_send.c. Fixed same bug in the function
5010 silc_server_send_notify as well.
5012 * If we receive NEW_ID packet for our own ID in the server, ignore
5015 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Removed the nickname from the Private Message Payload.
5020 Updated the code and the protocol specs.
5022 * Updated protocol specs for submitting to the IETF.
5024 * Tweaked the Random Number Generator a bit. Affected file
5025 lib/silccrypt/silcrng.c. Exported a new function
5026 silc_rng_[global]_add_noise which can be used to add more
5029 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Do not parse packets with different timeout when protocol
5032 is active -> may cause problem with rekey. Affected file
5035 * When server receives signoff notify it must not create
5036 new channel key if the client is on any channels since the
5037 sender of the signoff notify will create it.
5039 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Added printing of error messages during SKE protocol from the
5042 failure packet sent by server during SKE. Affected file
5045 * Removed the client's failure_callback handling with timeout
5046 and handle it immediately when received.
5048 * The SKE library returned wrong type in SUCCESS and FAILURE
5049 packets. They must be 32 bit MSB not 16 bit MSB.
5051 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5053 * Ok, rewrote the logic of the re-key and now it seems to work.
5054 I tested it on high traffic with frequent re-keys without
5055 problems. Added hmac_receive (and renamed hmac to hmac_send)
5056 in SilcClientConnection in lib/silcclient/client.h and
5057 in SilcIDListData in silcd/idlist.h. Also, removed the
5058 SilcPacketParserContext's cipher and hmac fields as they are
5059 not needed anymore and actually caused some problems when
5060 the ciphers and hmac's changed underneath the packet parser.
5062 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * If re-key protocol is active then process the incoming packets
5065 synchronously since we must assure that icoming packets encrypted
5066 with the old key is processed before the new keys is set to
5067 use. This is true other packets than for REKEY packets.
5068 Affected file silcd/server.c. The same was done to client library
5069 as well, affected file lib/silcclient/client.c.
5071 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Fixed bug in client and server to accept the force send if
5074 the packet is send from silc_[server/client]_packet_process
5075 function. Otherwise the packets are never delivered, oops.
5077 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Disable force sending of packets when REKEY protocol is active.
5080 We must assure that no packet is sent directly when rekey is
5081 performed. All packets must be sent through packet queue.
5082 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5083 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5084 function is silc_[server/client]_packet_send_real to check
5087 * Replaced the SIM paths from example config files to
5088 /usr/local/modules. Also, make install creates now
5089 /usr/local/silc/logs directory to hold all the SILC server
5092 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5094 * Made the configure.in.pre work on Solaris. Patch by salo.
5096 * Made all ciphers compatible with non-x86 machines. Defined
5097 CBC mode macros into lib/silccrypt/ciphers_def.h.
5099 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5101 * Fixed the make install.
5103 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5105 * When MAC computation fails the silc_packet_decrypt returned 0
5106 even though it was supposed to return -1. Fixed this. The
5107 affected file is lib/silccore/silcpacket.c.
5109 * Do not replace the config files in /etc/silc (in make install)
5110 if they already exist. Affected file ./Makefile.am.
5112 * Do not send re-key packets immediately but through packet queue.
5113 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5115 * Changed silc_net_check_host_by_sock to return FALSE if the
5116 IP/DNS could not be resolved. Though, it returns the IP address
5117 now even if it could not resolve it (but returns also FALSE).
5118 Affected file lib/silcutil/silcnet.[ch].
5120 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Added silc_pkcs_decode_identifier to decode the public key's
5123 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5124 Added also silc_pkcs_free_identifier. Added also new context
5125 SilcPublicKeyIdentifier.
5127 * Added -S option to the silc client. It is used to dump the
5128 contents of the specified public key file.
5130 * Changed the PKCS api to return the public key length when
5131 setting the public key.
5133 * Fixed a fatal bug in the public and private key file loading.
5134 Affected file lib/silccrypt/silcpkcs.c.
5136 * Execute the packet parsing for client with zero (0) timeout
5137 if the protocol is active. Affected file silcd/server.c.
5139 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Made the key generation options to the silcd program. Added
5142 -C option, equivalent to client's option.
5144 * Added new [ServerKeys] config section to the server. It
5145 configures the server's public and private key.
5147 * Defined generic Public Key Payload into the protocol
5148 specification to send specific type of public keys and
5151 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5152 public key or certificate.
5154 * Implemented the GETKEY command to the server and to the
5155 client library and on user interface.
5157 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Made preliminary `make install' work.
5161 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Added SilcServerRekey context into silcd/idlist.h.
5165 * Added the PFS support as defined in the specification to the
5166 SKE protocol. Affected files lib/silcske/*.c.

5169 the number of the SKE group that is used with PFS in re-key.
5170 Affected file silcd/idlist.h.
5172 * Added PFS re-key support to the server. Affected file is
5175 * Added silc_protocol_cancel to cancel execution of the next
5176 state of the protocol. Affected file is
5177 lib/silccore/silcprotocol.[ch].
5179 * Added the re-key support with and without PFS to the client
5180 library. Re-key is performed once in an hour, by default.
5182 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5183 Added silc_client_rekey_callback and silc_client_rekey_final.
5184 Affected files are lib/silcclient/protocol.[ch] and

5187 * Removed the `hmac_key' and `hmac_key_len' fields from the
5188 SilcClientConnection structure; not needed. Affected file is
5189 lib/silcclient/client.h.
5193 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Do not ask whether user wants to use the negotiated private key
5196 for private messages, just use it. Affected file is
5197 silc/local_command.c.
5199 * Added `send_enc_key' and `enc_key_len' fields to the
5200 SilcIDListData structure since they are needed in the re-key
5201 phase. Affected file is silcd/idlist.[ch].
5203 * Implemented the simple re-key protocol into the server.

5215 the PFS is to be performed in the re-key. Affected file is
5218 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5221 int64 of at least the xintXX size. If void * is less that 4
5222 bytes uint32 * will be used. Defined bool as boolean.
5224 * Changed _ALL_ unsigned long and unsigned int to uint32,
5225 unsgined short to uint16 in the source tree.
5227 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5228 not handle clients that has entry->data.registered == FALSE.
5229 They are not in the network anymore. Affected file is
5232 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Implemented the sending of the SERVER_SIGNOFF notify in the
5235 server. Affected file is silcd/server.c.
5237 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5238 Added also silc_notify_payload_encode_args into the
5239 lib/silccore/silcnotify.[ch].
5241 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5242 Affected file silcd/packet_receive.c.
5244 * Implemented the SERVER_SIGNOFF notify handling in the client
5245 library. Affected file lib/silcclient/client_notify.c. Also,
5246 implemnted the printing of the SERVER_SIGNOFF info to the
5247 application. Affected file silc/client_ops.c.
5249 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5250 if the deleting was successful. Affected file silcd/idlist.[ch].
5252 * Added support for public key authentication in the connection
5253 authentication protocol in the client library. Affected file
5254 lib/silcclient/protocol.c.
5256 * Changed the server's silc_idlist_get_clients_by_* interface
5257 to support already allocated array so that new entries may be
5258 added to pre-allocated array. Affected file silcd/idlist.[ch].
5259 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5260 and command replies.
5262 * All command reply functions in the server now calls the
5263 pending command callback even if error occured. This way the
5264 error will be delivered to the client as well. Affected files
5265 silcd/command.c and silcd/command_reply.c.
5267 * Fixed INFO command to return local server's info if no server
5268 was provided. Affected file lib/silcclient/command.c.
5270 * Removed RESTART command for good. Updated the code and the
5273 * Rewrote parts of the task system. It is a bit simpler now.
5274 Removed unsued task priorities. The affected files are
5275 lib/silcutil/silctask.[ch].
5277 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5279 * Moved the USERS printing from the library to the application.
5280 Affected files lib/silcclient/command.c and silc/client_ops.c.
5282 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Added channel key re-key support. The re-key is perfomed
5287 only by the router and is done once in an hour. Added `rekey'
5288 field to the SilcChannelEntry in the server. Affected files
5289 silcd/server.c and silcd/idlist.h.
5291 * Added silc_task_unregister_by_context into the file
5292 lib/silcutil/silctask.[ch].
5294 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5296 * Added SILC_UMODE_GONE mode to indicate when the client is not
5297 present in the SILC network. Added also support to the local
5298 command AWAY that will set this mode. Added support of showing
5299 "xxx is gone" in WHOIS command. The USERS command shows the
5300 gone status as well.
5302 * Fixed setting server and router operator privileges in the
5303 server's UMODE command. Affected file silcd/command.c.
5305 * Merged the SKE KE1 and KE2 payloads into one payload. The
5306 new KE payload is equivalent to the old KE2 payload.
5308 Cleaned up the SKE Start Payload parsing. It now uses the
5309 simple buffer unformatting to do the parsing. A lot faster
5312 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5313 to the SKE that is used to indicate whether both of the SKE
5314 parties should perform authentication. By default only the
5315 responder performs authentication. By setting this flag also
5316 the initiator must do authentication. By default it is unset
5317 since in normal SKE case, client to server connection, only
5318 the responder should do authentication. When doing SKE between
5319 two clients both should perform authentication. Updated the
5320 code and the protocol specs.
5322 * A little fix to IDENTIFY command in the server. Search the
5323 client first by hash not nickname. Affected file is
5326 * Fixed the silc_client_close_connection to support closing
5327 the client to client connections wihtout deleting too much
5328 data. Affected file lib/silcclient/client.c.
5330 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5331 are received if protocol used to be active but is not anymore
5332 the application would crash due to NULL pointer dereference.
5333 Affected files silcd/server.c and lib/silcclient/client.c.
5335 * Added `hash' field to the SilcClientConnection to include
5336 the hash function negotiated in the SKE protocol.
5338 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5339 to set the channel founder authentication data. A client can
5340 claim the founder rights later by providing the authentication
5341 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5342 This way the channel founder can regain the channel founder
5343 privileges even it is left the channel. This works only on
5344 local server and the client must be connected to the same
5345 server to be able to regain the founder rights. Updated the
5346 protocol specs accordingly.
5348 Added support to the CMODE command in the client to set the
5349 founder auth data. Read the README to see how to set it.
5351 Added support to the CUMODE command to claim the founder
5352 rights. Read the README to see how to do it.
5354 Added support for the founder authentication to the Channel
5355 Entry in the server. Affected file silcd/idlist.h.
5357 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5358 server's CMODE command. Affected file silcd/command.c.
5360 * Added the following new functions into lib/silccore/silcauth.[ch]:
5361 silc_auth_get_method and silc_auth_get_data.
5363 * The server now saves the remote hosts public key to the
5364 SilcIDListData pointer. Affected file silcd/protocol.c.
5366 * The normal server now does not remove the channel entry from
5367 the cache if the founder authentication data is set. It used
5368 to remove it if the founder was the last one on the channel on
5369 the server and left the channel. The auth data is saved and
5370 if the channel is re-joined later the old entry is used with
5371 the old auth data. Affected files silcd/command_reply.c and
5374 * Removed the `pkcs' field from the SilcIDListData structure
5375 in the server; it is not used. Affected file silcd/idlist.h.
5377 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * Fixed packet processing on slow links. Partial packets were
5380 never re-processed because the incoming data buffer was cleared
5381 by the application. Application must not directly clear the
5382 sock->inbuf, the packet processing routines handle it. Fixed
5383 this in client library and in server.
5385 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Fixed the WHOIS and IDENTIFY send reply function to really
5388 check whether to send list or just one entry. Affected file
5391 * Cleaned up the LEAVE command's channel key distribution. The
5392 affected file silcd/command.c.
5394 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5395 can enforce the channel mode as well. In that case the ID
5396 includes the ID of the server. The code now enforces the
5397 mode change if the router have different mode than the server.
5399 * The notify client operation with CMODE_CHANGE notify can now
5400 return NULL client_entry pointer if the CMODE was not changed
5401 by client. Application must check for this.
5403 * Added <Server ID> argument to INFO command to support server
5404 info fetching by Server ID.
5406 * Added silc_server_announce_get_channel_users to get assembled
5407 packets of channel users of the specified channel. Affected
5408 file silcd/server.[ch].
5410 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5411 was freed underneath the ID Cache.
5413 * Re-announce clients when the server received CHANNEL_CHANGE
5414 notify from the router. Affected file silcd/packet_send.c.
5416 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5419 crashed since it did not handle the fact that there is no cipher
5420 called "3" and didn't check the error condition. Now fixed.
5422 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5423 flag. It can be used to send message requests.
5425 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5427 * Implemented the RESTART command in the client.
5429 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5430 notice type messages. Added notice printing to the user
5433 * The channel keys are not re-generated if the channel's mode
5434 is PRIVKEY, ie private key on the channel exists. Affected
5435 files silcd/server.c and silcd/command.c.
5437 * Fixed a little bug in channel message delivery when channel
5438 private keys are set in the server. Affected file is
5439 silcd/packet_send.c.
5441 * Changed the setting on channel->on_channel = TRUE from the
5442 silc_client_save_channel_key to the JOIN command reply. The
5443 key payload is not received if the private channel key is set.
5444 Affected file lib/silcclient/command_reply.c and the
5445 lib/silcclient/client_channel.c.
5447 * When the CMODE_CHANGE notify is sent and the channel private
5448 key mode is removed the channel key must be re-generated in
5449 other cells as well. Added this support for the router in the
5450 silcd/packet_receive.c.
5452 * Added new local command NOTICE to send notice message on
5453 channel. Affected file silc/local_command.[ch].
5455 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Added new local command ME to the client. It is used to send
5458 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5459 some action. Affected file silc/local_command.[ch].
5461 * Changed channel_message and private_message client operations
5462 to deliver the message flags to the application. Added also
5463 the `flags' arguments to the silc_client_send_channel_message
5464 and silc_client_send_private_message functions. Affected file
5467 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Redefined the Private Message Payload to support private message
5470 keys and to support the new private message flags. Updated
5471 the protocol specs. Flags makes it possible to have for example
5472 CTCP style messages.
5474 * Added new type SilcPrivateMessagePayload and defined an API
5475 for it in the lib/silcclient/silcprivate.[ch].
5477 * Tested private message private keys successfully. Tested the
5478 private message key set, unset and list commands with the new
5481 * Redefined the Channel Message Payload to include the channel
5482 message flags (equal with private message flags) to support
5483 for example CTCP style messages.
5485 * Defined some of the message (for channel and private message)
5486 flags. Updated the protocol specs and added the flags to the
5487 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5489 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5491 * Added SilcKeyAgreementStatus type to the key agreement routines
5492 to indicate the current status and error if one occured.
5493 The status types are defined in the lib/silcclient/silcapi.h.
5495 * Added new local command KEY that is used to set and unset private
5496 keys for channels, set and unset private keys for private messages
5497 with remote clients and to send key agreement requests and
5498 negotiate the key agreement protocol with remote client. The
5499 key agreement is supported only to negotiate private message keys,
5500 it currently cannot be used to negotiate private keys for channels,
5501 as it is not convenient for that purpose.
5503 * Fixed a minor pending callback setting bug in the function
5504 silc_client_get_client_by_id_resolve, now the function works.
5505 Affected file lib/silcclient/idlist.c.
5507 * Added function silc_net_get_local_port to get local bound
5508 port by socket. Added to lib/silcutil/silcnet.[ch].
5510 * Added `sockets' and `sockets_count' fields to the SilcClient
5511 object. They hold the sockets of the listenning sockets in
5512 the client. Listenning sockets may be for example the key
5513 agreement server. Affected file lib/silcclient/client.[ch].
5514 Added functions the silc_client_add_socket and the
5515 silc_client_del_socket. They are exported to the application
5518 * Added ~./silc/clientkeys to support other client's public keys.
5520 * Renamed verify_server_key client operation to verify_public_key
5521 and added one argument to indicate the type of the connection
5522 (server, client etc.).
5524 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * Added silc_server_connection_auth_request to handle the
5527 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5528 silcd/packet_receive.[ch].
5530 * Added silc_server_send_connection_auth_request into the
5531 silcd/packet_send.c to send the connection auth request packet.
5533 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5536 * Fixed the public key authentication in responder side in the
5537 server. The `auth_data' pointer includes the SilcPublicKey
5538 not the path to the public key. Affected file silcd/protocol.c.
5540 * Implemented the public key authentication in the initiator side
5541 in the server. Affected file silcd/protocol.c.
5543 * Removed the [RedirectClient] config section from the server
5544 configuration. Is not needed and I don't want to implement it.
5546 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Cleaned up the CMODE command in the server. It now works
5549 correctly and supports all the modes defined in the protocol.
5550 Affected file is silcd/command.c.
5552 * Added `hmac_name' field to the SilcChannelEntry in the server
5553 to hold the default HMAC of the channel. It can be set when
5554 creating the channel (with JOIN command). Affected files
5557 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5558 type to indicate the change of the current cipher and hmac
5559 on the channel. Client can safely ignore the <cipher> argument
5560 (if it chooses to do so) since the CHANNEL_KEY packet will
5561 force the channel key change anyway. The <hmac> argument is
5562 important since the client is responsible of setting the new
5563 HMAC and the hmac key into use.
5565 * Fixed the CMODE command in the client library as well.
5567 * Tested CMODE command in router environment successfully.
5569 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * Show the version of the remote client (or server) when connecting
5572 to the server. It is logged to the log file. Affected file
5573 is silcd/protocol.c.
5575 * Fixed the KILLED notify handling in the client library. The
5576 client must be removed from all channels when receiving the
5579 Also, do not remove the client entry when giving the KILL
5580 command but when the KILLED notify is received.
5582 * Removed silc_idlist_find_client_by_nickname from the server.
5583 Not needed anymore. Affected files silcd/idlist.[ch].
5585 * Implemented the CHANNEL_CHANGE notify type handling to the
5586 server. Affected file silcd/server.c.
5590 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Added silc_server_send_notify_invite to send the INVITE
5593 notify between routers.
5595 * Implemented the INVITE command correctly to the server.
5597 * Implemented the INVITE notify type handling in the server.
5599 * Implemented the INVITE command to the client library and on the
5602 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5604 * Added function silc_server_get_client_resolve to find the
5605 client entry by ID from all ID lists and then resolve it
5606 (using WHOIS) if it cannot be found. Affected file is
5609 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Implemented the BAN command to the client library.
5613 * The JOIN command in the server now checks the invite list
5616 * Changed the silc_command_reply_payload_encode_va and the
5617 silc_command_payload_encode_va to support that if argument is
5618 NULL it ignores and checks the next argument. Affected file
5619 lib/silccore/silccommand.c.
5621 * Added silc_server_send_notify_ban to send the BAN notify
5622 type between routers.
5624 * Chaned the silc_notify_payload_encode to support that if
5625 argument is NULL it ignores and checks the next argument.
5626 Affected file lib/silccore/silcnotify.c.
5628 * Tested ban lists in router environment successfully.
5630 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Implemented BAN command to the server, in silcd/command.[ch].
5634 * Removed the BAN and INVITE_LIST modes from the CMODE command
5637 * Added function silc_string_match to regex match two strings.
5638 Affected files lib/silcutil/silcutil.[ch].
5640 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * Redefined parts of the SilcChannelEntry in the server to support
5643 the new ban and invite lists.
5645 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Redefined the INVITE command. The same command can be used to
5648 invite individuals to the channel but also to manage the invite
5649 list of the channel (to add to and remove from the invite list).
5650 Updated the protocol specs.
5652 * Added new command SILC_COMMAND_BAN that can be used to manage
5653 the ban list of the channel. Updated the protocol specs.
5655 * Removed the channel modes: the SILC_CMODE_BAN and the
5656 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5657 in the CMODE command. The equivalent features are now available
5658 using INVITE and BAN commands. Updated the protocol specs.
5660 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5661 in the network about change in the current ban list. The notify
5662 type is not used by the client.
5664 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5665 support the invite lists.
5667 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Added new function silc_string_regexify that converts string
5670 including wildcard characters into regex string that can
5671 be used by the GNU regex library. Added into the file
5672 lib/silcutil/silcutil.[ch].
5674 Added silc_string_regex_combine to combine to regex strings
5675 into one so that they can be used as one regex string by
5676 the GNU regex library. Added into the file
5677 lib/silcutil/silcutil.[ch].
5679 Added silc_string_regex_match to match two strings. It returns
5680 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5682 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5684 * Imported GNU regex to the soruce tree into lib/contrib.
5685 Fixed some compiler warning from the regex.c.
5687 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5689 * Fixed MOTD command in the server to work in router environment.
5691 * Fixed the MOTD command in the client library to support
5692 the server argument in the command.
5694 * Added `nickname_len' argument to the silc_idlist_add_client
5695 in the server, as the `nickname' argument may be binary data
5698 * Added silc_idlist_get_channels to return all channels from
5701 * Implemented LIST command to the server. Affected file is
5704 * Implemented the LIST command to the client library and on the
5707 * Added [<user count>] argument to the LIST command reply.
5708 With private channels the user count is not shown.
5710 * Updated TODO and README.
5712 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * The client entry's data.registered must be TRUE even with
5715 global client entry on global client list. The data.registered
5716 is used to check whether the client is anymore in the network,
5717 for example with WHOWAS command so it must be valid.
5719 * Fixed the WHOWAS command in the server. It now actually works
5720 in router environment. Added function into silcd/command_reply.c
5721 silc_server_command_reply_whowas_save.
5723 * Added silc_idlist_purge function to the silcd/idlist.c
5724 to periodically purge the ID Cache.
5726 * Fixed INFO command in the server. It works now in router
5727 environment. Added <server name> argument to the INFO command
5728 reply. Updated the protocol specs.
5730 * Fixed minor bug in silc_idcache_purge to not purge if the
5731 expire value is zero.
5733 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5734 they were buggy because of the WHOWAS information.
5736 * Fixed local command MSG to handle the async resolving of
5737 the remote client properly. It used to fail the first MSG.
5738 Affected file silc/local_command.c.
5740 * Added `data_len' field to SilcIDCache context.
5742 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Update TODO. Todo in commands in the server.
5746 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5748 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5749 used by routers as broadcast packet to inform other routers
5750 about the changed user mode.
5752 Implemented the notify handling in the server. Affected file is
5753 silcd/packet_receive.c. Added the function
5754 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5756 * Added new generic Channel Payload and deprecated the New Channel
5757 Payload. The New Channel Payload is now the generic Channel
5760 * Added new argument `mode' to the silc_server_send_new_channel
5761 as it is required in the Channel Payload now.
5763 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5764 and created a new and real SilChannelPayload to represent the
5765 new generic Channel Payload. Implemented the encode/decode
5766 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5768 * Added silc_server_get_client_channel_list to return the list
5769 of channels the client has joined for WHOIS command reply.
5770 Affected file silcd/server.[ch].
5772 * Implemented the channel list sending in the WHOIS command reply
5773 in server and in the client.
5775 Implemented the channel list displaying on the user interface
5776 as well. Affected file silc/client_ops.c.
5778 * Added silc_channel_payload_parse_list to parse list of Channel
5779 Payloads. It returns SilcDList list of SilcChannelPayloads.
5780 Client for example can use this function to parse the list of
5781 channels it receives in the WHOIS command reply. The caller
5782 must free the list by calling silc_channel_payload_list_free.
5783 Affected files lib/silccore/silcchannel.[ch].
5785 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5787 * Added one new argument <user mode> to the WHOIS command reply
5788 to return the mode of the user in SILC. Updated the protocol
5791 Implemented it to the server and client.
5793 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Fixed the mode printing on the user interface on joining.
5796 Affected file silc/client_ops.c.
5798 * Implemented the UMODE command and user modes in general to the
5799 client library and to the user interface.
5801 * Implemented the UMODE command to the server.
5803 * The server now sends UNKNOWN_COMMAND error status if client sends
5804 unknown command. Affected file silcd/command.c.
5806 * All server commands now handle the command identifier the right
5807 way when sending the command reply to the client. The client can
5808 use to identify the command replies with the identifier.
5810 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Added silc_server_get_client_route to resolve the route to
5813 the client indicated by the client ID. Affected file is
5816 * Added silc_server_relay_packet as general function to relay
5817 packet to arbitrary destination. This deprecates functions
5818 like _send_private_message_key, _relay_notify etc. Affected
5819 file is silcd/packet_send.[ch].
5821 Removed silc_server_send_key_agreement,
5822 silc_server_send_private_message_key and
5823 silc_server_packet_relay_notify functions from the file
5824 silcd/packet_send.[ch].
5828 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5829 server. Affected file silcd/packet_receive.[ch].
5831 * Implemented the KILL command to the client. Implemented the
5832 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5833 Affected files lib/silcclient/command[_reply].c and
5834 lib/silcclient/client_notify.c. Implemented the KILL notify
5835 printing in the user inteface.
5837 * Fixed a lot silc_parse_nick memory leaks from the client
5838 library in the file lib/silcclient/command.c.
5840 * Changed the silc_server_send_notify_on_channels's `sender'
5841 argument from SilcSocketConnection to SilcClientEntry to
5842 check the sender as entry and not as connection object and not
5843 to send to the client provided as argument. The affected file
5844 is silcd/packet_send.[ch].
5846 * The notify packets that are destined directly to the client used
5847 to not to be processed by the server. Now changed that and the
5848 server processes all notify packets. After relaying the packet
5849 to the client the notify packet is processed in the server.
5851 * The silc_server_free_client_data now checks whether there is
5852 pending outgoing traffic for the client and purges the data to
5853 the network before removing the client entry.
5855 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5858 an client is killed from the SILC Network. Updated the protocol
5861 Added new function silc_server_send_notify_killed to the
5862 silcd/packet_send.[ch].
5864 * Added function silc_server_packet_relay_notify to relay notify
5865 packets that are destined directly to a client. In this case
5866 the server does not process the notify packets but merely relays
5867 it to the client. Affected file silcd/packet_send.[ch].
5869 Added also silc_server_packet_process_relay_notify to check
5870 whereto relay the notify. Affected file is
5871 silcd/packet_receive.[ch].
5873 * Implemented the KILL command to the server.
5877 * Added the backup schema desgined last fall to the protocol
5878 specs for everyone to see. The specification is in the
5879 *-spec-xx.txt draft and the packet type definitions for the
5880 backup routers is in *-pp-xx.txt draft. Thusly, added also
5881 new packet type SILC_PACKET_CELL_ROUTERS.
5883 * A big security problem in the implementation discovered. The
5884 signoff of an client did not cause new channel key generation
5885 which it of course should've done. The channel keys must be
5886 always re-generated when client leaves (or signoffs) the channel.
5887 The silc_server_remove_from_channels funtion now handles
5888 the channel key re-generation.
5890 * Added `sender' argument to the silc_server_send_notify_on_channels
5891 to not to send the client provided as argument. Affected file
5892 silcd/packet_send.[ch].
5894 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * Implemented OPER and SILCOPER commands into the server and
5899 * Added silc_auth_verify and silc_auth_verify_data to verify
5900 the authentication directly from the authentication payload.
5901 It supports verifying both passphrase and public key based
5902 authentication. Affected file lib/silccore/silcauth.[ch].
5904 * Added `hash' field to the SilcIDListData structure. It is the
5905 hash negotiated in the SKE protocol. Affected file is
5908 * Slight redesigning of the SilcAuthPayload handling routines.
5909 Do not send SilcPKCS but SilcPublicKey as argument.
5911 * Implemented the public key authentication support to the
5912 serverconfig. The public key is loaded from the provided path
5913 and saved as authentication data to void * pointer. Thus,
5914 changed the unsigned char *auth_data to void *auth_data;
5916 * Fixed SHUTDOWN command to send the reply before the server
5917 is shutdown. :) Affected file silcd/command.c.
5919 * Fixed fatal bug in CONNECT command. The hostname was invalid
5920 memory and server crashed. Affected file silcd/command.c.
5922 * Fixed fatal bug in CLOSE command. The server_entry became
5923 invalid but was referenced later in the command. Affected file
5926 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5928 * Fixed fatal bug in failure packet handling. Server ignored
5929 the failure and thus crashed when it came.
5933 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5936 that the command may be executed only once in (about) 2 seconds.
5937 The old SILC_CF_LAG flag is same but allows command bursts up
5938 to five before limiting.
5940 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5941 server code. Various commands now includes the CF_LAG_STRICT
5942 flag to disallow any kind of miss-use of the command.
5944 * Fixed the silc_buffer_unformat to not to allocate any data
5945 if the length of the data is zero. It used to allocate the
5946 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5948 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Changed the format of AdminConnection configuration section
5951 in the server. Added username of the admin to the format.
5952 Affected files silcd/serverconfig.[ch].
5954 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5955 to return admin configuration data by host, username and/or
5958 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Implemented WHOWAS command to the server. Added the functions:
5962 silc_server_command_whowas_parse,
5963 silc_server_command_whowas_send_reply,
5964 silc_server_command_whowas_from_client and
5965 silc_server_command_whowas_from_server
5967 * Added <Client ID> argument to the WHOWAS command reply. Updated
5968 the protocol specs accordingly.
5970 * Implemented WHOWAS command and command_reply to the client
5973 Implemented the WHOWAS printing on the user interface.
5975 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5977 * Added new argument to the WHOWAS command reply, the real name.
5978 It is an optional argument. Updated the protocol specs.
5980 * Added SilcIDCacheDestructor callback that is registered when
5981 the SilcIDCache is allocated. The callback is called when
5982 an cache entry in the ID Cache expires, or is purged from the
5983 cache. Added into lib/silccore/idcache.[ch].
5985 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5986 to destruct the client entries when the cache entry expires.
5987 Other ID Cache's in server and in the client library ignores
5990 * If the ID Cache entry's `expire' field is zero then the entry
5991 never expires. Added boolean `expire' argument to the
5992 silc_idcache_add function in the lib/silccore/idcache.[ch].
5993 If it is TRUE the default expiry value is used.
5995 * Added silc_server_free_client_data_timeout that is registered
5996 when client disconnects. By default for 5 minutes we preserve
5997 the client entry for history - for WHOWAS command.
5999 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Added support to the server to enforce that commands are not
6002 executed more than once in 2 seconds. If server receives
6003 commands from client more frequently, timeout is registered
6004 to process the commands. Affected file silcd/command.c.
6005 Added new function silc_server_command_process_timeout.
6007 * Changed NICK_NOTIFY handling in client library to check that
6008 if the client's nickname was changed, so there is no need to
6009 resolve anything from the server.
6011 * Removed error printing from the WHOIS and IDENTIFY commands.
6012 If error occurs then it is ignored silently in the client library.
6013 The application, however, may map the received error to
6014 human readable error string. The application currently maps
6015 the NO_SUCH_NICKNAME error to string.
6017 * Made the command status message public to the application. Moved
6018 them from lib/silcclient/command_reply.c to
6019 lib/silcclient/command_reply.h. The application can map the
6020 received command status to the string with the
6021 silc_client_command_status_message function.
6023 * Added check to the server to check that client's ID is same
6024 as the Source ID in the packet the client sent. They must
6027 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Added dist-bzip hook to the Makefile.am to make bzip2
6030 compressed distributions.
6032 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Server now enforces the maximum length for the nickname and
6035 the channel as protocol specification dictates. 128 bytes for
6036 nickname and 256 bytes for channel name.
6038 * Moved the WHOIS printing to the application. The client libary
6039 does not print out the WHOIS information anymore, the application
6040 must do it. Renamed silc_client_command_reply_whois_print to
6041 the silc_client_command_reply_whois_save.
6043 The client's idle time is also sent to the application now, and
6044 the idle is shown on screen.
6046 * Added silc_client_command_reply_identify_save to save the
6047 received IDENTIFY entries.
6049 * Do not check for channel private keys in message sending and
6050 reception if the channel does not have the PRIVKEY mode set.
6051 Affected file lib/silclient/client_channel.c.
6053 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6056 just surfaced after chaning the JOIN procedure.
6058 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6060 * Added silc_client_get_clients_by_list to get client entries
6061 from Client ID list, that is returned for example by JOIN
6062 and USERS command replies. The application should use this
6063 function for example when JOIN command reply is received to
6064 resolve the clients already on the channel (library does not
6065 do that anymore as USERS command reply is not used in the JOIN
6066 procedure anymore). Affected files lib/silcclient/silcapi.h and
6067 lib/silcclient/idlist.c.
6069 * JOIN command reply and USERS command reply returns now SilcBuffer
6070 pointers instead of unsigned char pointers when returning
6071 the client list and mode list.
6073 * Added <Client ID> argument to the JOIN command reply, mainly
6074 for the server to identify for which client the command was
6075 originally sent. Updated protocol specs accordingly.
6077 * Added SilcDlist private_key pointer to the SilcChannelEntry
6078 in the client to support the channel private keys. Affected
6079 file is lib/silcclient/idlist.h.
6081 * Added SilcChannelPrivateKey argument to the function
6082 silc_client_send_channel_message so that application can choose
6083 to use specific private ke if it wants to. If it is not provided,
6084 the normal channel key is used, unless private keys are set.
6085 In this case the first (key that was added first) is used
6086 as the encryption key.
6088 * Implemented the support for channel private key handling.
6089 Implemented the following functions:
6091 silc_client_add_channel_private_key,
6092 silc_client_del_channel_private_keys,
6093 silc_client_del_channel_private_key,
6094 silc_client_list_channel_private_keys and
6095 silc_client_free_channel_private_keys
6097 Affected file lib/silcclient/client_channel.c.
6099 * Added the support for the private keys in the channel message
6100 sending and encryption and in the message reception and
6101 decryption. Affected funtions are
6102 silc_client_send_channel_message and silc_client_channel_message.
6104 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6106 * Added SKE's key verify callback to the client library's
6107 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6109 * Removed the statement that server (or router) must send USERS
6110 command reply when joining to the channel so that the client
6111 knows who are on the channel. Instead, the client list and
6112 client's mode list is now sent in the JOIN command reply to the
6113 client who joined channel. This is better solution.
6115 * Added function silc_server_get_users_on_channel and function
6116 silc_server_save_users_on_channel to the silcd/server.[ch].
6118 * Removed function silc_server_command_send_users from the
6121 * Do not show topic on the client library anymore. The topic is
6122 sent in the command reply notify to the application and the
6123 application must show the topic now.
6125 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Added client searching by nickname hash into the IDENTIFY and
6128 WHOIS commands in the server as they were clearly missing from
6129 them. Affected file is silcd/command.c.
6131 * Fixed a bug in private message receiving in the client library.
6132 The remote ID was freed and it wasn't supposed, now it is
6135 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6137 * Minor fix to the channel payload; allocate the data area, as it
6138 needs to be of specific length.
6140 * If the key agreement port is zero then the operating
6141 system will define the bound port. Affected files are
6142 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6144 * Added new function silc_channel_payload_decrypt into the file
6145 lib/silccore/silcchannel.[ch].
6147 * Moved the channel message etc, check from silc_packet_decrypt
6148 to applications. The library calls now a generic
6149 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6150 when the packet is either normal or special. This was done to
6151 allow more wide range of checking that was not allowed when
6152 the code was in library. Now applications can do virtually any
6153 checks to the packet and return to the library the decision how
6154 the packet should be processed. Affected files are
6155 lib/silccore/silcpacket.[ch].
6157 Added silc_server_packet_decrypt_check to the server and
6158 silc_client_packet_decrypt_check to the client library.
6160 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6161 to send with specified source and destination information.
6163 * Channel message delivery between routers was broken after the
6164 channel key distribution was fixed earlier. The channel key
6165 was used be to distributed to other routers as well which is not
6166 allowed by the protocol. Now this is fixed and channel keys
6167 really are cell specific and the channel message delivery between
6168 routers comply with the protocol specification.
6170 * Fixed various commands in server to check also the global list
6171 for the channel entry and not just the local list. The affected
6172 file silcd/command.c.
6174 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6176 * Added assert()s to buffer formatting and unformatting routines
6177 to assert (if --enable-debug) when error occurs. Affected
6178 file: lib/silcutil/silcbuffmt.c.
6180 * Changed to auto-reconnect to check whether the remote host is
6181 router and register the re-connect timeout if it is. It used
6182 to check that whether we are normal server, but router must do
6183 auto-reconnect with another router as well. Affected file
6186 * Removed the [<key len>] option from CMODE command as the cipher
6187 name decides the key length, nowadays. See the defined ciphers
6188 from the protocol specification.
6190 * Added [<hmac>] option to the CMODE command to define the HMAC
6191 for the channel. Added SILC_CMODE_HMAC channel mode.
6193 * Added [<hmac>] option for the JOIN command so that user can
6194 select which HMAC is used to compute the MACs of the channel
6197 * Added Hmac field to the Channel Message Payload. The integrity
6198 of plaintext channel messages are now protected by computing
6199 MAC of the message and attaching the MAC to the payload. The
6200 MAC is encrypted. Now, it is clear that this causes some
6201 overhead to the size of the packet but rationale for this is that
6202 now the receiver can verify whether the channel message decrypted
6203 correctly and also when private keys are set for the channel the
6204 receiver can decrypt the packet with several keys and check from
6205 the MAC which key decrypted the message correctly.
6207 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6208 lib/silccrypt/silccipher.[ch].
6210 * Added silc_hash_len to return the digest length into the
6211 lib/silcrypt/silchash.[ch].
6213 * Rewrote parts of Silc Channel Payload interface in the
6214 lib/silccore/silcchannel.[ch]. The encode function now also
6215 encrypts the packet and parse function decrypts it.
6217 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6219 * Fixed a minor formatting bug in the SKE's key material processing.
6220 It actually might have processed the keys wrong way resulting
6223 * Redefined the mandatory HMAC algorithms and added new algorithms.
6224 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6225 and hmac-md5 truncated to 96 bits. The mandatory is now
6226 hmac-sha1-96. Rest are optional (including the one that used
6227 to be mandatory). Rationale for this is that the truncated HMAC
6228 length is sufficient from security point of view and can actually
6229 make the attack against the HMAC harder. Also, the truncated
6230 HMAC causes less overhead to the packets. See the RFC2104 for
6233 * Added new [hmac] configuration section. The SKE used to use
6234 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6235 is of course wrong. The official names that must be proposed in
6236 the SKE are the ones defined in the protocol specification
6237 (hmac-sha1-96 for example). The user can configure any hmac
6238 using any hash function configured in the [hash] section. At
6239 least, the mandatory must be configured.
6241 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6243 * Added HMAC list to the SKE proposal list. It has now both
6244 hash algorithm list and HMAC list. This makes the protocol
6245 incompatible with previous versions. The SKE now seems to work
6246 the way it is supposed to work, for the first time actually.
6248 * Defined plain Hash algorithms to the protocol specification.
6251 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6253 * Implemented support for key agreement packets into the server.
6254 Added functions silc_server_key_agreement and
6255 silc_server_send_key_agreement. Other than these functions,
6256 server has nothing to do with this packet.
6258 * Added support for private message key packets into the server.
6259 Added functions silc_server_private_message_key and
6260 silc_server_send_private_message_key.
6264 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6265 called in the protocol's final callback instead in the END
6266 protocol state. This makes a little more sense and in the same
6267 time in client we can use the same protocol routines for normal
6268 key exchange and to key agreement packet handling as well.
6270 * Added to both client's and server's KE protocol context the
6271 SilcSKEKeyMaterial pointer to save the key material. We will
6272 bring the key material to the protocol's final callback by doing
6273 this. The final callback must free the key material.
6275 * Added SKE's packet_send callback into client's KE protocol
6276 context so that the caller can choose what packet sending function
6277 is used. This way we can use different packet sending when
6278 doing normal SKE when doing key agreement packet handling (in
6279 the key agreement packet handling we do not want to encrypt
6282 * Implemented the responder side of the key agreement routines
6283 in the client. The client can now bind to specified port and
6284 accept incoming key negotiation. The key material is passed
6285 to the application after the protocol is over.
6287 * Implemented the processing of incoming Key Agreement packet
6288 in the client. Added function silc_client_key_agreement to
6291 * Implemented the intiator side of the key agreement routines
6292 in the client. The client can now initiate key agreement with
6293 another remote client. The key material is passed to the
6294 application after the protocol is over.
6296 * Created client_keyagr.c to include all the key agreement
6299 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6300 SILC_TASK_CALLBACK except that it is not static.
6302 * Created client_notify.c and moved the Notify packet handling
6303 from the client.[ch] into that file.
6305 * Created client_prvmsg.c and moved all private message and
6306 private message key routines from the client.[ch] into that file.
6308 * Create client_channel.c and moved all channel message and
6309 channel private key routines from the client.[ch] into that file.
6311 * Changed silc_client_get_client_by_id_resolve to resolve with
6312 WHOIS command instead of IDENTIFY command, in the file
6313 lib/silclient/idlist.c.
6315 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6317 * Implemented the SKE's responder side to the Client library.
6319 * When FAILURE is received to the protocol do not trust it
6320 blindly. Register a timeout to wait whether the remote closes
6321 the connection as it should do it, only after that process the
6322 actual failure. This was changed to both client and server.
6324 * Added client_internal.h to include some of the structures
6325 there instead of client.h in lib/silcclient/.
6327 * Added function silc_task_unregister_by_callback to unregister
6328 timeouts by the callback function.
6330 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6332 * Some "Incomplete WHOIS info" errors has been appearing on the
6333 log files. Took away the entry->userinfo check from WHOIS
6334 reply sending. The entry->userinfo is now " " if client did not
6335 provide one. I thought this was fixed earlier but something
6336 is wrong still. Let's see if the error still appears.
6338 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Fixed a minor bug in the login when the channel key is
6341 re-generated in the server. It used to generate the key in
6342 wrong order and thus caused problems in the channel traffic.
6344 * Fixed a minor bug in channel key distsribution after
6345 KICK command. The key was not sent to the router even though
6348 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Added silc_ske_process_key_material_data as generic routine
6351 to process any key material as the SILC protocol dictates. The
6352 function is used by the actual SKE library but can be used by
6353 applications as well. This relates to the private message keys
6354 and the channel private keys since they must be processed the
6355 same way the normal SILC session keys. The protocol dictates
6356 this. Affected files: lib/silcske/silcske.[ch].
6358 Added also silc_ske_free_key_material to free the
6359 SilcSKEKeyMaterial structure.
6361 * Defined silc_cipher_set_key function to set the key for
6362 cipher without using the object's method function. The affected
6363 files: lib/silccrypt/silccipher.[ch].
6365 * Implemented silc silc_client_add_private_message_key,
6366 silc_client_add_private_message_key_ske,
6367 silc_client_del_private_message_key,
6368 silc_client_list_private_message_keys and
6369 silc_client_free_private_message_keys functions in the
6372 Added functions silc_client_send_private_message_key to send
6373 the Private Message Key payload and silc_client_private_message_key
6374 to handle incoming Private Message Key payload.
6376 * Added Cipher field to the Private Message Key payload to set
6377 the cipher to be used. If ignored, the default cipher defined
6378 in the SILC protocol (aes-256-cbc) is used.
6380 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6382 * Removed lib/silcclient/ops.h file.
6384 Redefined parts of the SILC Client Library API. Created new
6385 file silcapi.h that deprecates the ops.h file and defines the
6386 published Client Library API. Defined also private message key
6387 API and channel private key API into the file.
6389 This is the file that the application must include from the
6390 SILC Client Library. Other files need not be included by
6391 the application anymore.
6393 * Added new key_agreement client operation callback and also
6394 defined the Key Agreement library API for the application.
6396 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6398 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6399 is used by clients to request key negotiation between another
6400 client in the SILC network. If the negotiation is started it
6401 is performed using the SKE protocol. The result of the
6402 negotiation, the secret key material, can be used for example
6403 as private message key.
6405 Implemented the Key Agreement payload into the files
6406 lib/silccore/silauth.[ch].
6408 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Redefined ciphers for the SILC protocol. Added some new ciphers
6411 and defined the key lengths for the algorithms. Changed the
6412 code accordingly. The default key length is now 256 bits.
6414 * Fixed SKE key distribution function silc_ske_process_key_material
6415 when the key length is more than 128 bits. The default key
6416 length in SILC is now 256 bits.
6418 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6419 to indicate unsupported algorithm.
6421 * Renamed rijndael.c to aes.c and all functions as well.
6423 * Fixed a long standing channel key setting bug in client library.
6424 Weird that it has never surfaced before.
6426 * Fixed bug in channel deletion. If the entire channel is removed
6427 then it must also delete the references of the channel entry
6428 from the client's channel list as the client's channel entry and
6429 the channel's client entry share same memory.
6431 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6433 * Implemented CONNECT and SHUTDOWN commands in the client.
6435 * Implemented CLOSE command to the client.
6437 * Added the function silc_idlist_find_server_by_name into the
6438 files silcd/idlist.[ch].
6440 Added the function silc_idlist_find_server_by_conn into the
6441 files silcd/idlist.[ch].
6443 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6445 * DIE command was renamed to SHUTDOWN. Updated the both code
6448 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6449 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6451 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6454 * Added function silc_server_create_connection function to create
6455 connection to remote router. My server implementation actually
6456 does not allow router to connect to normal server (it expects
6457 that normal server always initiates the connection to the router)
6458 so the CONNECT command is only good for connecting to another
6461 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6463 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6464 or some other client was kicked from the channel.
6466 Implemented the handling of the notify type to both client
6469 Implemented silc_server_send_notify_kicked to send the KICKED
6470 notify. It is used to send it to the server's primary router.
6472 * Implemented the KICK command into server and client.
6474 * Added `query' argument to the silc_idlist_get_client function
6475 to indicate whether to query the client from server or not if
6478 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6479 to indicate that the client is not channel founder.
6483 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Removed the rng context from SilcPacketContext structure and
6486 changed that the packet routine uses the Global RNG API.
6488 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6490 * Added support for quit message that client can "leave" on the
6491 channel when it quits the SILC. It is ditributed inside the
6492 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6494 Added silc_server_free_client_data that will take the
6495 signoff message as argument.
6497 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6499 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6501 * Updated parts of the protocol specification to keep it up
6504 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6507 payloads in one packet.
6509 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6510 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6511 use now the new List flag.
6513 * Also deprecated the following packet types: REPLACE_ID,
6514 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6516 * Added list support for Notify packet in server.
6518 * Added silc_server_send_notify_channel_change to send the
6519 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6520 the silc_server_send_replace_id.
6522 * Added silc_server_send_notify_nick_change to send the
6523 NICK_CHANGE notify type. Deprecates the function
6524 silc_server_send_replace_id.
6526 * Added silc_server_send_notify_join to send the JOIN notify type.
6527 Deprecates the function silc_server_send_new_channel_user.
6529 * Added silc_server_send_notify_leave to send LEAVE notify type.
6530 Deprecates the function silc_server_send_remove_channel_user.
6532 * Added silc_server_send_notify_cmode and
6533 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6534 types. Deprecates the silc_server_send_set_mode function.
6536 * Added SERVER_SIGNOFF notify type to indicate that server has
6537 quit. This means that all clients on the channel from that
6538 server will drop. This can be also used when netsplit happens.
6540 Deprecated REMOVE_ID packet type since it is not needed anymore
6543 Added silc_server_send_notify_server_signoff to send the
6544 SERVER_SIGNOFF notify type. Deprecates the function
6545 silc_server_send_remove_id.
6547 Added also silc_server_send_notify_signoff to send the
6548 SIGNOFF notify type.
6550 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6551 SILC protocol from this day on. Changed the protocol
6552 specification as well.
6554 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6555 notify type. It is used between routers to notify about
6556 topic changes on a channel.
6558 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6561 * Partly updated the protocol specification to comply with the
6562 changes now made. It is still though a bit outdated.
6564 * The JOIN notify type now takes one extra argument <Channel ID>.
6565 The packet used to be destined to the channel but now the
6566 JOIN type may be sent as list thus it is impossible to
6567 destine it to any specific channel. By adding this argument
6568 it is again possible.
6570 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6572 * Added CREDITS file. The CHANGES and CREDITS file will appear
6573 in the distribution as well.
6575 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6577 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6578 types in the server's silcd/packet_receive.c.
6580 * Implemented CMODE and CUMODE to work in router environment.
6582 * Fixed minor encoding and decoding buglet from the
6583 lib/silccore/silcmode.c.
6585 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6588 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6590 * Changed all SilcConfigServer* and silc_config_server* to
6591 SilcServerConfig* and silc_server_config*, respectively.
6594 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6596 * Associated the ID (client or server ID) to the Authentication
6597 Payload to avoid any possibility of forging. Updated the
6598 protocol specification and the code accordingly.
6600 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * The RSA key length is now save to the RsaKey context in the
6603 key generation process in lib/silccrypt/rsa.c. The key length
6604 is now used to figure out the maximum size of the block allowed
6605 to be encrypted/signed.
6607 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6608 is equivalent to the silc_mp_mp2bin but does not allocate any
6611 * Changed silc_mp_mp2bin API to take length argument. If it is
6612 non-zero then the buffer is allocated that large. If zero, then
6613 the size is approximated using silc_mp_sizeinbase, which however
6616 * Created Global RNG API which is global RNG that application can
6617 initialize. After initializing, any routine anywhere in the
6618 code (including library) can use RNG without allocating a new
6619 RNG object. This was done to allow this sort of use of the
6620 RNG in code that has no chance to allocate RNG object. All
6621 applications currently allocate this and many routines in the
6622 library use this. Affected file lib/silccrypt/silcrng.[ch].
6624 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6625 it to use the Global RNG API.
6627 * Defined Authentication Payload into protocol specification that
6628 is used during SILC session to authenticate entities. It is
6629 used for example by client to authenticate itself to the server
6630 to obtain server operator privileges.
6632 Implemented this payload into the lib/silccore/silcauth.[ch].
6633 Implemented also routines for public key based authentication
6634 as the new protocol specification dictates.
6636 Moved definitions of different authentication methods from
6637 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6639 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6640 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6641 silc_pkcs_verify_with_hash functions into the file
6642 lib/silccrypt/silcpkcs.[ch].
6644 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6646 * The client entry's userinfo pointer must be always valid.
6647 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6648 will fail since it requires the userinfo. Now, the userinfo
6649 is allocated as "" if actual userinfo does not exist. Actually,
6650 it must exist and it is totally Ok to drop client connections
6651 that does not announce the userinfo. However, we will make
6652 this workaround for now.
6654 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6655 to return the remote port by socket.
6657 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6660 SILC_SERVER_PENDING_EXEC and added an new macro
6661 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6662 data or when error occurs while processing the pending command.
6664 Added new argument `destructor' into silc_server_command_pending
6665 and to the SilcServerCommandPending object. This destructor is
6666 now called after calling the pending callback or if error occurs
6667 immediately. If error occurs the actual pending callback won't
6668 be called at all - only the destructor. The destructor may be
6669 NULL if destructor is not needed.
6671 All this applies for client library code as well. Similar
6672 changes were made there as well for the pending commands.
6674 In the client, the application must now allocate the
6675 SilcClientCommandContext with the silc_client_command_alloc
6678 * Added reference counter to the SilcServerCommandContext. Added
6679 function silc_server_command_alloc and silc_server_command_dup
6682 Same type of functions added to the client library for the same
6685 * Removed the cmd_ident from IDListData away since it is now
6686 global for all connections. It is the command identifier used
6687 in command sending and with pending commands. The affected file
6690 * Added reference counter to the SilcSocketConnection objecet to
6691 indicate the usage count of the object. The object won't be
6692 freed untill the reference counter hits zero. Currently only
6693 server uses this, and client ignores it. The client must be
6694 set to use this too later. The affected files are
6695 lib/silccore/silcsockconn.[ch]. Added also the function
6696 silc_socket_dup to increase the reference counter.
6698 This was mainly added because it is possible that the socket
6699 is removed underneath of pending command or other async
6700 operation. Now it won't be free'd and proper DISCONNECTING
6701 flags, etc. can be set to avoid sending data to connection that
6702 is not valid anymore.
6704 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6705 the connection. After that it sets SILC_SET_DISCONNECTED.
6706 It is, however, possible that the socket data is not still freed.
6707 The silc_server_packet_process now checks that data is not
6708 read or written to connection that is DISCONNECTED. The socket
6709 get's freed when the reference counter hits zero.
6711 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6713 * Changed the client operation API: channel_message operation's
6714 `sender' is now the client entry of the sender, not the nickname
6715 and the `channel' is the channel entry, not the channel name.
6717 In the private_message operation the `sender' is now also the
6718 client entry of the sender not the nickname.
6720 Affected file is lib/silcclient/ops.h and all applications
6721 using the client operations.
6723 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6725 * Moved the calling of ops->connect() from connect_to_server_final
6726 into receive_new_id functin since that is the point when the
6727 client is actually allowed to send traffic to network. The
6728 affected file is lib/silcclient/client.c.
6730 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6732 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6733 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6734 (if needs broadcasting) instead of broadcasting the packets one
6735 by one which would make a burst in the network traffic.
6737 * Added `broadcast' argument to the functions in silcd/server.[ch]
6738 silc_server_create_new_channel[_with_id] to indicate whether
6739 to send New Channel packet to primary router.
6741 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6743 * Added new function into the silcd/server.[ch] files:
6744 silc_server_create_new_channel_with_id to create new channel with
6745 already existing Channel ID.
6747 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6748 lib/silccore/silcpacket.h. This packet is used t send list of
6749 Set Mode payloads inside one packet. Server uses this to set
6750 the modes for the channels and clients on those channels, that it
6751 announced to the router when it connected to it. The protocol
6752 specification has been updated accordingly.
6754 * The silc_server_new_channel did not handle the packet coming
6755 from normal server as it normally does not send that. However,
6756 when it announces its channels it does send it. Implemented
6757 the support for that.
6759 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6760 into the file lib/silccore/id.h.
6762 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6764 * Fixed memory leaks in the functions silc_idlist_del_client,
6765 silc_idlist_del_channel and silc_idlist_del_server in the file
6766 silcd/idlist.c. All of those leaked like a sieve.
6768 * Fixed some small memory leaks in the client's function
6769 silc_client_notify_by_server.
6771 * Added functions into silcd/server.c: silc_server_announce_clients,
6772 silc_server_announce_channels and silc_server_announce_server.
6773 These functions are used by normal and router server to announce
6774 to its primary router about clients, channels and servers (when
6775 router) that we own. This is done after we've connected to the
6778 These functions effectively implements the following packet types:
6779 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6780 and SILC_PACKET_NEW_ID_LIST.
6782 * Added new functions into the silcd/packet_receive.[ch]:
6783 silc_server_new_id_list, silc_server_new_channel_list and
6784 silc_server_new_channel_user_list to handle the incoming
6785 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6787 * Added support of changing Channel ID in the function
6788 silc_server_replace_id. If the server that announces a channel
6789 to the router already exists in the router (with same name but
6790 with different Channel ID), router is responsible to send
6791 Replace ID packet to the server and force the server to change
6792 the Channel ID to the one router has.
6794 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6795 client that the Channel ID has been changed by the router. The
6796 normal server sends this to the client. Client must start using
6797 the new Channel ID as the channel's ID.
6799 Implemented handling of this new type into lib/silcclient/client.c
6800 into the function silc_client_notify_by_server.
6802 * Added new function silc_idlist_replace_channel_id into the files
6803 silcd/idlist.[ch] to replace the Channel ID.
6805 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6807 * Call silc_server_command_identify_check always when processing
6808 the IDENTIFY command in silcd/command.c
6810 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6813 send keepalive packets. The packet can be sent by clients,
6814 servers and routers.
6816 Added function silc_socket_set_heartbeat into the file
6817 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6818 If not set, the heartbeat is not performed. The actual
6819 heartbeat is implemented in the low level socket connection
6820 library. However, application is responsible of actually
6823 Added silc_server_send_heartbeat to send the actual heartbeat
6824 packet into silcd/packet_send.[ch]. Server now performs
6825 keepalive with all connections.
6827 * Added silc_task_get_first function into lib/silcutil/silctask.c
6828 to return the timeout task with shortest timeout. There was a bug
6829 in task unregistration that caused problems. TODO has been
6830 updated to include that task system must be rewritten.
6832 * The client library will now resolve the client information when
6833 receiving JOIN notify from server for client that we know but
6834 have incomplete information.
6836 * Rewrote parts of silc_server_remove_from_channels and
6837 silc_server_remove_from_one_channel as they did not remove the
6838 channel in some circumstances even though they should've.
6840 * Encryption problem encountered in server:
6842 The LEAVE command used to send the Channel Key packet to the
6843 router immediately after generating it. However, the code
6844 had earlier sent Remove Channel user packet but not immediately,
6845 ie. it was put to queue. The order of packets in the router
6846 was that Channel Key packet was first and Remove Channel User
6847 packet was second, even though they were encrypted in the
6848 reverse order. For this reason, MAC check failed. Now, this
6849 is fixed by not sending the Channel Key packet immediately but
6850 putting it to queue. However, this is more fundamental problem:
6851 packets that are in queue should actually not be encrypted
6852 because packets that are sent immediately gets encrypted
6853 actually with wrong IV (and thus MAC check fails). So, packets
6854 that are in queue should be encrypted when they are sent to
6855 the wire and not when they put to the queue.
6857 However, the problem is that the current system has not been
6858 designed to work that way. Instead, the packet is encrypted
6859 as soon as possible and left to the queue. The queue is then
6860 just purged into wire. There won't be any fixes for this
6861 any time soon. So, the current semantic for packet sending
6864 o If you send packet to remote host and do not force the send
6865 (the packet will be in queue) then all subsequent packets to the
6866 same remote host must also be put to the queue. Only after the
6867 queue has been purged is it safe again to force the packet
6870 o If you send all packets immediately then it safe to send
6871 any of subsequent packets through the queue, however, after
6872 the first packet is put to queue then any subsequent packets
6873 must also be put to the queue.
6875 Follow these rules and everything works fine.
6877 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Added new function silc_server_remove_clients_by_server to
6880 remove all client entries from ID list when the server connection
6881 is lost. In this case it is also important to invalidate all
6882 client entires as they hold the invalid server entry. This
6883 fixes fatal bug when server has lost connection and will reconnect
6886 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6888 * Made some sanity checks to silc_server_daemonise like to check
6889 whether the requested user and group actually exists.
6891 * Added sanity check to SKE's silc_ske_responder_finish to check
6892 that the public and private key actually is valid.
6894 * Invalidate the client's nickname when receiving Replace ID
6895 packet and the Client ID is being replaced. This means that the
6896 server will query the nickname if someone needs it (client)
6899 * Sort the ID Cache in client library when the ID Cache data
6900 has changed (needs sorting).
6902 * Do not allow for SILC client to create several connections to
6903 several servers. The client does not support windows right now
6904 and generating multiple connections causes weird behaviour.
6906 Irssi-silc client does support windows and can handle several
6907 connections without problems, see: www.irssi.org and SILC plugin.
6909 * Fixed some places where client was added to the IDList. The
6910 rule of thumb is following (in order to get everything right):
6911 If the client is directly connected local client then the
6912 `connection' argument must be set and `router' argument must be
6913 NULL to silc_idlist_add_client function. If the client is not
6914 directly connected client then the `router' argument must
6915 bet set and the `connection' argument must be NULL to the
6916 silc_idlist_add_client function.
6918 * The funtion silc_server_packet_send_local_channel actually did
6919 not check whether the client was locally connected or not. It
6920 does that now. Fixed a bug related to LEAVE command.
6922 * Fixed Remove Channel User payload parsing bug in server's
6923 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6925 * The server's silc_server_save_channel_key now checks also the
6926 global ID list for the channel as it might not be in the local
6927 list. Fixed a bug related to LEAVE command.
6929 * Is this the end of the [<unknown>] buglet that has been lurking
6930 around for a long time? A little for loop fix in server's
6931 silc_server_command_whois_parse that is used by both IDENTIFY
6932 and WHOIS command. At least, this was a clear bug and a cause
6933 of one type of [<unknown>] buglet.
6935 * WHOIS and IDENTIFY commands call the function
6936 silc_server_command_[whois/identify]_check function even if
6937 we are not router server.
6939 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Added --with-gmp configuration option. If set the GMP
6942 is always compiled in the SILC source tree. If not set then
6943 it is checked whether the system has the GMP3 installed. If
6944 it has then the GMP won't be compiled (the system's headers
6945 and library is used), if it doesn't have it then the GMP is
6946 compiled in the SILC source tree.
6948 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Changed RSA private exponent generation to what PKCS #1
6951 suggests. We try to find the smallest possible d by doing
6952 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6953 not security fix but optimization.
6955 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6957 * Added new config entry [Identity] to fork the server and run
6958 it as specific user and group. A patch from Bostik.
6960 * Imported Dotconf configuration library into lib/dotconf.
6961 This will be used to create the SILC configuration files later.
6962 It will appear in the distsribution after this commit.
6964 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6966 * A big code auditing weekend happening. Auditing code for
6967 obvious mistakes, bugs and errors. Also, removing any code
6970 Removed files for being obsolete:
6972 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6973 inline in the file lib/silcutil/silcbuffer.h)
6975 o lib/silcutil/silcbufutil.c (the header has inline versions)
6977 Changed code to fix possible error conditions:
6979 o The buffer formatting routines now check that the destination
6980 buffer really has enough space to add the data. This applies for
6981 both buffer formatting and unformatting
6982 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6983 unformatting was changed to accomodate following rules:
6984 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6985 sent to the function while XXX_*STRING will not allocate or copy
6986 the data into the buffer. Instead it sets the pointer from the
6987 buffer into the pointer sent as argument (XXX_*STRING used to
6988 require that the pointer must be allocated already). This change
6989 makes this whole thing a bit more consistent and more optimized
6990 (note that the data returned in the unformatting with XXX_*STRING
6991 must not be freed now). The routines return now -1 on error.
6993 o Tried to find all code that use buffer_format and buffer_unformat
6994 and added return value checking to prevent formatting and
6995 especially unformatting errors and possible subsequent fatal
6998 o Changed ske->x and ske->KEY to mallocated pointers in
6999 lib/silcske/silcske.h. Fixed possible data and memory leak.
7001 o Added return value checking to all *_parse* functions. Fixed
7002 many memory leaks as well.
7004 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7005 so that buffer overflows would not happen. All code now also
7006 checks the return value as it can fail.
7008 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7010 * Added reconnection support to server if the normal server looses
7011 its connection to the router (for example if router is rebooted).
7012 The server performs normal reconnection strategy implemented
7013 to the server. Affected file silcd/server.c.
7015 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7017 * Added new packet type SILC_PACKET_SET_MODE that is used to
7018 distribute the information about changed modes (for clients,
7019 channels and clients channel modes) to all routers in the
7020 network. Updated the protocol specification accordingly.
7022 Added functions into silcd/packet_send.c and
7023 silcd/packet_receive.c: silc_server_send_set_mode,
7024 silc_server_set_mode.
7026 Added new files silcmode.[ch] into lib/silccore that implements
7027 the encoding and decoding of Set Mode Payload. Added new type
7028 SilcSetModePayload. Moved the definitions of different modes
7029 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7031 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7033 * Oops, a little mistake in server's connection authentication
7034 protocol. The protocol is not ended with FAILURE but with
7035 SUCCESS if the authentication is Ok. :) Affected file is
7038 * Implemented NICK_CHANGE notify handling in server in the file
7039 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7040 the local clients on the channel. After the changing nickname
7041 in router environment snhould work and the [<unknown>] nickname
7042 should appear no more.
7044 The silc_server_replace_id function that receives the Replace ID
7045 payload now sends the NICK_CHANGE notify type also in the file
7046 silcd/packet_receive.c
7048 * Changed WHOIS and IDENTIFY command to support the maximum amount
7049 of arguments defined in protocol specs (3328 arguments). This
7050 fixed a bug that caused problems when there were more than three
7053 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Added extra parameter, command identifier, to the
7056 silc_client_send_command so that explicit command identifier
7059 Changed that ID list routines uses specific command identifier
7060 when sending WHOIS/IDENTIFY requests to the server so that they
7061 can be identified when the reply comes back.
7063 Affected files lib/silcclient/command.[ch],
7064 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7066 * Added `sender' argument to silc_server_packet_send_to_channel
7067 to indicaet the sender who originally sent the packet to us
7068 that we are now re-sending. Ignored if NULL. Affected file
7069 silcd/packet_send.[ch].
7071 * Added some server statistics support in silcd/server_internal.h
7072 SilcServerStatistics structure and around the server code. Also
7073 send some nice statistics information when client is connecting
7076 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7078 * Fixed channel ID decoding in server's JOIN command reply in
7079 silcd/command_reply.c
7081 * Fixed braodcasting of replace ID payload to not to send it if
7082 we are standalone server in silcd/packet_receive.c.
7084 * Fixed all channel message sending routines to not to send
7085 packets to clients that has router set, since they are routed
7086 separately in the same function earlier. Affects file
7087 silcd/packet_send.c and all channel packet sending functions.
7089 * In USERS reply, res_argv[i] are not allocated, the table
7090 is allocated. Thus changed that free the table, not its
7093 * In server's whois_check and identify_check if the client is
7094 locally connected do not send any WHOIS commands - they are not
7097 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7099 * Fixed some minor bugs in client when sending WHOIS command. The
7100 arguments was in wrong order.
7102 * Removed statis function add_to_channel from server in
7103 silcd/command.c that was previously used with the joining but
7106 * Tested USERS command in router environment successfully with two
7107 routers, two servers and two clients.
7109 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Reorganized the USERS command and command reply in client library
7112 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7113 When the command is given by user we register a pending command
7114 callback that will reprocess the command after the reply has been
7115 received from the server. When reprocessing the packet we then
7116 display the information. Thus, the USERS information is displayed
7117 now in the command callback instead of in the command reply
7118 callback. The processing of the command is same as previously
7119 when server has sent the command reply in the JOINing process.
7121 * Added to USERS command in silcd/command_reply.c to join the client,
7122 we didn't use to know about, to the channel after we've created
7123 a client entry for it. Also, for clienet we did know already still
7124 check whether it is on the channel or not and add it if not.
7126 * Removed silc_server_command_join_notify as the function and its
7129 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7131 * Changed the client's pending command handling to the same as the
7132 server's pending command handling. It is also now possible to
7133 execute command reply functions from other command reply
7134 function as the function callbacks for commands and command
7135 replies are one and same. The pending commands are not static
7136 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7137 in client connection context. Thus, pending commands are server
7138 connection specific as it is convenient.
7140 Changed the function silc_client_command_pending and
7141 silc_client_command_pending_del and added new function
7142 silc_client_command_pending_check. Removed the
7143 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7146 * Added cmd_ident, current command identifier, to the client
7147 connection context in lib/silcclient/client.h to keep track on
7148 command identifiers used in command sending. Client's command reply
7149 function handling now supports the mandatory command identifiers.
7151 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7152 funtions in client to fully support pending command callbacks.
7154 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7155 as one of the arguments to the application in the command reply
7158 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7159 before first releasing SILC but came back. Now it is removed again
7160 and should come back nomore. The FORWARDED flag was used only
7161 by the JOINing procedure by forwarding the command packet to router.
7162 Now, the JOINing procedure has been changed to more generic (due
7163 to various router environment issues) and FORWARDED is not needed
7164 anymore for anything. The protocol specification is yet to be
7167 Now, removed silc_server_packet_forward from server and the flag
7168 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7170 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7172 * Renamed NAMES command to USERS command. The NAMES was named that
7173 due to historical reasons. Now it is renamed. Also, rewrote
7174 parts of the USERS command. The nickname list is not sent anymore
7175 by the server. Only Client ID and mode lists are sent in the USERS
7176 command. Changed this also to the protocol specification.
7178 The client now resolves the names and stuff after it receives
7179 the USERS list from the server when joining to the channel.
7181 * WHOIS and IDENTIFY commands has been changed to support multiple
7182 Client ID's per command. One can now search for multiple users
7183 in the network by sending only one WHOIS or IDENTIFY command.
7184 Changed the code and the protocol specifications.
7186 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7187 uses silc_server_command_whois_parse to parse the request. */
7189 * If normal server, do not parse the WHOIS and IDENTIFY requests
7190 before sending it to the router. Saves some time.
7192 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7194 * Fixed JOIN command on client library. Wrong number of arguments
7195 used to crash the client.
7197 * Added silc_server_channel_has_global function to check whether
7198 channel has global users or not.
7200 * Added silc_server_channel_has_local function to check whether channel
7201 has locally connected clients on the channel.
7203 * The silc_server_remove_from_one_channel now checks whether the
7204 channel has global users or not after given client was removed from
7205 the channel. It also checks whether the channel has local clients
7206 on the channel anymore. If it does not have then the channel entry
7207 is removed as it is not needed anymore.
7209 * The silc_server_notify now checks on JOIN notify whether the joining
7210 client is one of locally connected or global. If it is global then
7211 the channel has now global users on the channel and that is marked
7212 to the channel entry. Also, it now saves the global client to
7213 global list who is joining and JOINs it to the channel. This is
7214 for normal server, that is.
7216 Changed silc_server_send_notify_on_channel,
7217 silc_server_packet_relay_to_channel and
7218 silc_server_packet_send_to_channel check if we are normal server
7219 and client has router set (ie. global client) do not send the
7220 message to that client, as it is already routed to our router.
7222 * Implemented LEAVE notify type handling in silc_server_notify
7225 * Tested LEAVE command in router environment successfully. Tested
7226 with two routers, two servers and two clients.
7230 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7232 * Implemented SIGNOFF notify type handling in silc_server_notify
7235 * silc_server_remove_id now removes the client entry from all channels
7236 it has joined and thusly sends SIGNOFF notify type.
7238 * Rewrote the NAMES list generation in server by removing two excess
7239 loops. The lists are created now inside one loop.
7241 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7243 * silc_server_remove_channel_user checks now also global list
7244 for channel and client.
7246 * silc_server_new_channel_user checks now both local and global
7247 list for channel and client. Fixed a bug in client id decoding.
7248 Used to decode wrong buffer.
7250 * silc_server_channel_message checks now both local and global
7251 list for channel entry.
7253 * Tested channel joining (hence JOIN) in router environment
7254 successfully. Tested with two routers, two servers and two
7257 * Tested channel message sending in router environment successfully.
7259 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7261 * Added silc_server_save_channel_key into server.[ch] to save the
7262 received channel key in Channel Key payload processing. It is
7263 also used in JOIN command reply handling.
7265 Equivalent function silc_client_save_channel_key added into
7266 client.[ch] into client library.
7268 * Changed JOIN command reply to send information whether the channel
7269 was created or not (is existing already) and the channel key
7270 payload. Changed protocol specs accordingly.
7272 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7273 the request was sent by ID and not by nickname. Crashed on
7276 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7278 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7279 now correctly save the received data.
7281 * silc_server_free_sock_user_data now notifies routers in the
7282 network about entities leaving the network.
7284 At the same time implemented functions silc_server_remove_id
7285 and silc_server_send_remove_id to receive and send REMOVE_ID
7286 packets. The packet is used to notify routers in the network
7287 about leaving entities. The ID removed will become invalid in
7290 * Added function silc_idlist_del_server into server. Removes and
7291 free's server entry from ID list.
7293 * silc_server_private_message function now checks, if we are router,
7294 that the destination ID really is valid ID, naturally.
7296 * In router when NEW_ID packet is received (for new client) the
7297 hash of the Client ID is saved in the ID Cache but the
7298 client->nickname is set to NULL, instead of putting the hash
7301 IDENTIFY command now also checks that client->nickname must be
7302 valid. If it is not if will request the data from the server who
7303 owns the client. Added new function
7304 silc_server_command_identify_check.
7306 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7307 to set the command to already allocated Command Payload.
7309 * Tested private message sending in router environment with two
7310 routers, two servers and two clients. Fixed minor bugs and now
7313 * Fixed segfault from client's NAMES command. Used to crash if
7316 * Forwarded packets must not be routed even if it is not destined
7317 to the receiver. Changed server code comply with this.
7319 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7321 * Added `require_reverse_mapping' boolean value to ServerParams
7322 structure. If TRUE (not default) the server will require that
7323 the connecting host has fully qualified domain name.
7325 If the reverse mapping is not required and hostname could not be
7326 found the IP address is used as hostname.
7328 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7330 * Implemented version string checking to both client and server.
7331 The check is incomplete currently due to the abnormal version
7332 strings used in development version of SILC.
7334 * Changed all command functions in server to use the new
7337 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7339 * Changed char *data to unsigned char *data in ID Cache system to
7340 support binary data as ID Cache data. Changed code to support
7341 binary data in lib/silccore/idcache.c.
7343 * Renamed silc_server_packet_relay_command_reply to
7344 silc_server_command_reply as it is normal packet receiving
7345 function. Rewrote the function to accept command replys for
7346 servers and not only for clients.
7348 * Mark remote router always as registered server if we are connecting
7349 to it. Otherwise, commands sent by the router to us are ignored.
7351 * All ID List find routines now returns the ID Cache Entry pointer
7352 as well if requested.
7354 * WHOIS command works now in router environment, tested with two
7355 routers, two servers and two clients.
7357 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7358 in router environment (as it is almost equivalent to WHOIS) but
7359 hasn't been tested thoroughly. Added new functions:
7361 silc_server_command_identify_parse
7362 silc_server_command_identify_send_reply
7363 silc_server_command_identify_from_client
7364 silc_server_command_identify_from_server
7366 * Disabled route cache adding because adding two different ID's with
7367 same IP replaces the old cache entry thus giving wrong route.
7368 The entry->router->connection is always the fastest route anyway
7369 so route cache may not be needed. Of course, new routes maybe
7370 established after receiving the ID when the entry->router->connection
7371 might not be anymore the most optimal.
7373 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7375 * Add route cache for received ID for fast routing.
7377 * Added silc_server_packet_route to route received packet on router
7378 that is not destined to us.
7380 * Renamed silc_server_get_route to silc_server_route_get.
7382 * Added id_string and id_string_len fields into SilcServer to
7383 include encoded ServerID for fast comparing without excess
7384 encoding of the ID's.
7386 * Cleaned up WHOIS command on server side. Added following static
7389 silc_server_command_whois_parse
7390 silc_server_command_whois_check
7391 silc_server_command_whois_send_reply
7392 silc_server_command_whois_from_client
7393 silc_server_command_whois_from_server
7395 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7396 arguments in command replies. All command functions should be
7397 updated to use this macro.
7399 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7401 * Minor typo fixes on command reply handling on server.
7403 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7405 * Added silc_server_command_add_to_channel internal routine to add
7406 the client to the channel after router has created the channel and
7407 sent command reply to the server.
7409 * Added generic silc_server_send_command to send any command from
7412 * Use static buffer with ID rendering instead of duplicating data.
7414 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7416 * Fixed a channel user mode bug when joining to a channel server gave
7417 everybody channel founder rights, oops.
7419 * We mark ourselves as the router of the incoming server connection
7420 if we are router ourselves. This way we can check in some packet
7421 sending functions whether it is locally connected server. For
7422 incoming router connections we put NULL.
7424 * For router sending packets locally means now always sending the
7425 packet cell wide; to local clients and local servers. For normal
7426 server sending packet locally means sending it to only local
7429 * Fixed the JOIN command to really work in router environment. If the
7430 channel is created it is always created by the router. Router is
7431 also responsible of making the initial joining to the channel,
7432 sending JOIN notify to the sending server and distributing
7433 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7434 does not exist server doesn't do anything else but forward the
7435 command to the router which performs everything.
7437 * Added silc_server_send_channel_key function to send the Channel Key
7440 * Added silc_server_create_channel_key to create new channel key. The
7441 channel key is now re-generated everytime someone joins or leaves
7442 a channel, as protocol dictates. Note: channel->key_len is the
7445 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7447 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7448 packet_receive.[ch] to separate packet sending and receiving
7449 routines. The server.[ch] now includes everything else including
7450 actual packet processing (writing and reading data) and other
7453 Renamed silc_server_private_message_send_internal to
7454 silc_server_send_private_message. The routine is still though
7455 used only to relay private messages as server does not send
7456 private messages itself.
7458 Renamed silc_server_new_channel to silc_server_create_new_channel
7459 and added new function sicl_server_new_channel that handles the
7460 incoming New Channel packet. Added also new sending function
7461 silc_server_send_new_channel to send New Channel Payload.
7463 * Added new function silc_server_notify to process incoming notify
7464 packet to the server/router. Server may then relay the notify
7465 to clients if needed.
7467 * Added new function silc_server_new_channel_user to process incoming
7468 New Channel User packet. Router will redistribute the packet and
7469 send JOIN notify to its local clients and locally connected servers
7470 if needed. Normal server will send JOIN notify to its local client
7471 on same channel when received this packet. Added also corresponding
7472 sending function silc_server_send_new_channel_user to sent the
7475 * Added boolean route argument to send_notif_to_channel and
7476 packet_send_to_channel functions to attempt to route the packet
7477 if it is TRUE and send only locally if it is FALSE.
7479 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7481 * silc_server_replace_id now broadcasts the received replace ID
7482 packet if it is not broadcast packet already. The router must
7483 broadcast to inform other routers about changed ID.
7485 * Added backpointer to server's router into SilcServer context in
7486 silcd/server_internal.h.
7488 * Fixed silc_server_packet_broadcast to send correct broadcast
7491 * The channel key is now distributed to the local client as soon
7492 as it is received from the router (in router environment) so that
7493 no other packet may be sent for the channel until client has
7496 * silc_server_remove_channel_user now broadcasts the received
7497 Remove Channel User packet if it is not broadcast packet already.
7498 The router must broadcast to inform other routers about removed
7501 * Added users field into SilcPacketContext that is a reference count
7502 of the context. One can increase the reference count by calling
7503 silc_packet_context_dup which is now changed to just increase the
7504 reference count instead of duplicating the data. The reference
7505 count is decresed by calling silc_packet_context_free that will
7506 free the data after the reference count hits zero.
7508 For now on the packet context and everything allocated into it
7509 (including the raw packet from network) must be freed by calling
7510 the new silc_packet_context_free function. Added also new function
7511 silc_packet_context_alloc that must be used now to allocate the
7512 context. This also means that if a routine is asynchronous from
7513 silc_[client/server]_packet_parse_type the packet context must
7514 be duplicated by calling silc_packet_context_dup. Otherwise it
7515 gets free'd after silc_[client/server]_packet_parse_type returns.
7516 Also, one must remember that if packet is duplicated then its
7517 reference count must be decresed by calling the free function as
7518 many times as it was duplicated.
7520 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7521 from both client and server.
7523 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7525 * Made joining to a channel working in router environment.
7527 * Cleaned up JOIN command on server side and create function
7528 silc_server_command_join_channel internal routine to make the
7531 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7533 * Changed silc_command_pending list to SilcDList. Also, added
7534 `ident' field to SilcServerCommandPending structure to identify
7535 the reply and to call correct callback.
7537 Added silc_server_command_pending_check function to replace the
7538 corresnponding macro. The silc_command_pending list is not
7541 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7542 to set identifier to previously allocated Command Payload. It
7543 is used to set identifier for command when resending Command
7546 * Added silc_command_payload_encode_payload to encode Command
7547 Payload buffer from SilcCommandPayload structure.
7549 * Added silc_argument_payload_encode_payload to encode Argument
7550 payload buffer from SilcArgumentPayload structure.
7552 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7554 * Changed WHOIS command to support router connection on server side.
7555 The whois request is always sent to router unless the server is
7556 standalone server. After server has received the reply from the
7557 router will it send the reply to the client.
7559 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7560 broadcast received broadcast packet. The function is used only
7561 by router. The broadcast packet is always sent to the router's
7564 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7565 render given ID to printable string, for log files for example.
7567 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7569 * Made basic router to router connections working. At least they
7570 can now connect to each other but nothing really works the way
7571 they are supposed - yet.
7573 * Added new initiator token to RouterConnection configuration
7574 file in silcd/serverconfig.[ch]. It is used to tell whether we
7575 are the initiator to the remote router or whether we'll expect
7576 the other end to connect.
7578 * Moved registering of listener task to silc_server_init, hence
7579 the server starts listenning as soon as it is run, even if it
7580 does not have connections to other routers. Let's see how well
7583 * Changed default connection retry timeouts for more suitable in
7586 * Removed cipher and such arguments from silc_idlist_add_client
7587 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7588 Added new function silc_idlist_add_data to add the keys and stuff
7591 * Added SilcIDListData structure and added it to SilcClientEntry
7592 and SilcServerEntry as their first field in the structure. This
7593 way we can explicitly cast the ID entries to the SilcIDListData
7594 structure and get common data for the entries. In past, we had
7595 to first check what type of connection it is and then cast it to
7596 correct ID entry type. Now, we can directly cast the opaque
7597 pointer to the SilcIDListData (no matter what ID entry it actually
7598 is) and get the data needed.
7600 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7602 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7603 in some circumstances even if threre were timeout tasks, though not
7604 IO tasks, but tasks anyway. Now fixed.
7606 * Defined SilcServerConnection structure to hold connection specific
7607 stuff about directly connected servers and routers. The definition
7608 is currently in silcd/server_internal.h. I thought about having
7609 a bit more important role fro this struct but for now it is used
7610 only when connecting to other server (or router actually).
7612 * Added connecting retry support in server when connecting to
7613 router(s). The retry feature implement exponential backoff
7614 algorithm. Also, added SilcServerParams structure to hold default
7615 parameters for server. For now, it include these retry settings
7616 and are hard coded. After server is moded to be as Silc Server
7617 Library this structure will be more important.
7619 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7621 * Changed client librarys channel->clients table to SilcList and
7622 changed code accordingly.
7624 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7626 * Changed client's channel table to SilcList and changed code
7627 accordingly. Also changed SilcChannelClientEntry to include back-
7628 pointer to the channel so that client entry can use that structure
7629 as list as well and we have fast cross-reference to the channel.
7630 This change dramatically decreased the complexity of channel
7631 handling with client entry and vice versa (removed one extra
7632 loop when searching for channel entry from many functions).
7634 * Changed server->sim from table to SilcDList and changed code
7637 * NAMES command can now be used from user interface. It will show
7638 the user list on the channel, neatly.
7640 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7641 Code now saves realname of the user if it becomes available.
7643 * Renamed configure.in to configure.in.pre and made ./prepare
7644 script to automatically add correct version string to
7645 configure.in which it creates from configure.in.pre.
7647 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7649 * NAMES command reply now shows users mode with the nickname when
7652 * Moved silc_client_ch[u]mode[_char] functions from
7653 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7654 place sucks, they are utility functions and should be in some
7657 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7659 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7662 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7666 * Added TRQ (efficient deque and list library) into lib/trq. This is
7667 a very good list library that is currently used in the SILC. Defined
7668 SilcList API over the library because I didn't like the API very
7669 much. See lib/trq/silclist.h for the API and examples of how to
7670 use the API. Fixed various places in the code to use the new
7671 SilcList API. The SilcList is meant for lists that has a structure
7672 already defined as a list. It is not suitable to add just some
7673 context to the list (in TRQ, the context is the list actually).
7675 So, I defined SilcDList that can be used for the purpose where
7676 predefined list structure does not exit. This can be used as
7677 such list. Now some context just can be added to the SilcDList.
7678 Currently this list is not used in the SILC just yet, though there
7679 are a lot places where this can replace dynamically allocated
7680 tables and I will fix these places, later, to use SilcDList.
7681 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7682 and use TRQ internally).
7684 Also fixed some annoying warning messages that the original TRQ
7685 code generated. Also minor changes to TRQ's Makefile.in.
7687 * Added support for querying by Client ID to both WHOIS and
7688 IDENTIFY commands into server, as required by the protocol.
7690 * Removed method function pointers from SilcBuffer structure. They
7691 weren't used to anything and just increased the context size for
7692 no good reason. This change also made silc_buffer_alloc and
7693 silc_buffer_free functions inline functions.
7695 * Disabled command flooding detection support until it's fixed so
7696 that it accepts commands in but does not execute them more than once
7699 * Added silc_net_localhost(), to return local hostname, into
7700 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7701 that must be initialized before calling silc_client_init.
7703 * Added new function: silc_server_send_notify_on_channels to send
7704 notify messages to all channels client has joined. It is assured
7705 that the message is sent only once per client.
7707 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7708 lib/silcutil/silcutil.[ch] as silc_format function. The new
7709 function is generic and is used by server as well, not only by
7710 the logging routines.
7712 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7713 the provided version string was not acceptable. Added new function:
7714 silc_ske_check_version into lib/silcske/silcske.h. The function
7715 must be implemented by the application (client or server) and it
7716 does not reside in the SKE library. The function checks the version
7717 string remote end sent.
7719 * Added back pointers (to opaque context and to SilcSocketConnection)
7720 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7722 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7723 duplicate packet context structure.
7725 * Changed `notify' client operation to send same arguments as client
7726 receives from server except for ID's. ID's are mapped to correct
7727 ID entry and that is returned. Also, if channel entry is not sent
7728 by server but the notify is for channel the channel entry is sent
7729 to application (otherwise application doesn't know that it is for
7730 channel (library gets it from packet's Destination ID)).
7732 * Added silc_client_remove_from_channels into client library to
7733 remove a client from all channels it has joined to. Used when
7734 received SIGNOFF notify from server. Added also new function
7735 silc_client_replace_from_channels to replace old ID entry with
7736 new ID entry on all channels. Used when received NICK_CHANGE
7739 * Fixed ID Cache list handling in silc_idlist_get_client in
7740 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7741 to get (or query) client by ID.
7743 * Updated TODO list.
7745 * Added connection authentication status message defined by the
7746 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7747 support for these into the code in client and server side.
7749 * Added generic function silc_client_send_command to send any command
7750 with variable argument list. Application should use this function
7751 to send commands if the command functions provided by the library
7752 does not suite for the application's user interface needs.
7754 * Added new `failure' client operation. Application is notified about
7755 received failure packet if client is executing a protocol. In this
7756 case the protocol's execution has failed.
7758 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7759 is required by the protocol.
7761 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7762 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7765 * Added status flag to SilcSKE object to indicate realtime status
7766 of the SKE protocol.
7768 * Application receives now exactly same command reply arguments as
7769 the library receives from server. However, if ID is received the
7770 corresponding ID entry is returned to the application (eg. Client
7771 ID is mapped to correct SilcClientEntry entry and that is returned).
7772 Changed command_reply client operation due to this change.
7774 * Changed all ID's in commands and in command replys as ID Payloads.
7775 Change affected both client and server side codes.
7777 All ID's sent in SILC network (with execption of ID's in SILC
7778 Packet header) are sent in ID Payload to support variable length
7781 * Server now notifies nick changes and notifies all clients on
7782 the channels about the new nickname (about the new Client ID,
7785 * Implemented CMODE command to change channel modes. Supports all
7786 channel modes defined by the protocol specs except ban and invite
7787 lists. (Also, private channel key mode is supported but support for
7788 setting private channel key in client is missing, thus, this mode
7789 has no effect on client side (except that server requires that the
7790 client uses private channel key and normal channel traffic does not
7793 Also, invite mode works per se, but INVITE command does not work
7794 yet correctly, so you can set channel as invite only channel but
7795 inviting clients to the channel does not work (it is yet to be
7796 thought what's the best way to do it).
7798 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7799 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7800 Implemented CUMODE command to change user's mode on the channel.
7801 Supports all modes defined by the protocol specs.
7803 * Added NAMES command reply to return users modes on the channel.
7805 * Removed unnecessary and slow ciphers from lib/silccrypt.
7807 * Set SO_KEEPALIVE option to connection sockets by default.
7809 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7811 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7812 redefined the Notify Payload into protocol specs.
7814 * Added silc_id_payload_parse_id to get ID directly from raw
7817 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7819 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7820 accept searching by Client ID as well.
7822 * Added support for LEAVE and SIGNOFF notify types in client library.
7824 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7825 to parse ID Payload from raw data.
7827 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7829 * Added flags parameter into silc_ske_assemble_security_properties
7830 function in lib/silcske/silcske.[ch].
7832 * Changed notify client operation to fit better for notify messages
7833 sent by server. The notify payload received from server is now
7834 passed to the application (after parsing it to SilcNotifyPayload).
7835 It is application's responsibility to retrieve the arguments
7836 from the payload and show the message the way it wants. The message
7837 sent by server is implementation specific.
7839 * Changed public keys to comply with the protocol specification.
7840 Old public keys are not supported anymore and are not compatible.
7842 * Removed nickname from Channel Payload as the latest draft removed
7843 it. The client must resolve the nickname from the NAMES command
7844 reply received when it joined the channel.
7846 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7848 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7850 * Fixed some errors in protocol specification drafts.
7852 * Created lib/silccore/silcnotify.c to implement Notify Payload
7853 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7854 generic payloads described by protocol specifications. The file
7855 includes implementations for ID Payload and Argument Payload.
7857 * Changed Command Payload implementation to use the new Argument
7858 Payload. Changed command_xxxx_payload to command_payload_xxxx
7859 to comply with SILC coding conventions.
7861 * Added suppport for Argument Payload handling in Notify Payload
7862 implementation as protocol requires it. Added the new support
7863 into server and client lib as well.
7865 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7867 * Added support for multiple nicknames on same channel. [n] is
7868 added locally to the nickname if there are more than one same
7869 nicknames on the channel.
7871 * Server now sends all nicknames that matched WHOIS request.
7872 Client also shows the list received from server.
7874 * Added TOPIC command to client side. User can now set and show
7875 current topic on channel.
7877 * Added MOTD command to client and server. Also, server sends the
7878 motd when client connects to the server.
7880 * Changed version strings to comply ISO 8601.
7882 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7884 * Fixed protocol error handling in client library. It should now
7885 cope even if the SKE fails for some reason.
7887 * Made new protocol specification drafts for submitting to IETF.
7889 * Implemented TOPIC command to server in silcd/command.c.
7891 * Added two new notify types into lib/silccore/silcnotify.h:
7892 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7893 notify nickname change and topic setting/change on a channel.
7895 * API change of command_reply operation in client library. The
7896 application gets now the status type received from server as well.
7898 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7900 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7902 * Cras fixed and optimized the packet handling even further and
7903 it should work now. Minor change to the prototype of function
7904 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7906 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7908 * Added new function into lib/silcutil/silcschedule.[ch]:
7909 silc_schedule_with_fd to select() a specified fd. The function
7910 returns after timeout expires or data arrives or goes. The
7911 function is used by packet routines to wait that all data is
7912 received from network.
7914 * Fixed data reading from network in lib/silccore/silcpacket.c.
7915 The code now assures that all data is read from the fd and then
7916 continues packet processing. This was a bug fix since the code
7917 used to drop some data in some circumstances.
7919 * Added new function into lib/silcclient/client.[ch]:
7920 silc_client_start_key_exchange to start key exchange after
7921 connection has been established to server. The code internally
7922 now uses this funtion but its main purpose was to provide it
7923 for applications that perform their own connecting. After
7924 application has created a connection it merely calls this
7925 function to start the key exchange between client and server.
7926 The library takes care of everything else after that.
7928 Updated also lib/silcclient/README to explain the usage of
7931 * Do not send to application information that connection has
7932 been established. Application gets notified it by connect
7935 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7937 * Applied cras's patch to add silc_schedule_one function. The
7938 function runs scheduler once and returns.
7940 * Fixed the scheduler after cras messed it up. The timeout
7941 handling works now as it's supposed to work.
7943 * Added into lib/silccore/ silcnotify.h to include notify
7944 message types support. Changed silc_server_send_notify*
7945 functions, in server.[ch], to support those new notify types.
7946 Added the support for the notify types into client library,
7947 as well. Added new notify client operation into ops.h in
7950 * Changed silc_server_packet_send_to_channel to send normal
7951 packets instead of just channel message packets. The function
7952 is now used to send the notify packets to channels. It is not
7953 used to send channel message packets anymore, as server never
7956 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7957 va_arg()s as it seems to require it nowadays. I guess, if SILC
7958 is compiled with older va_arg() the new code should work anyway.
7960 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7962 * Splitted core library. Core library (lib/silccore) includes
7963 now only SILC protocol specific core (and common) components.
7964 Created new utility library (lib/silcutil) that includes more
7965 generic purpose stuff. The stuff for util library was taken
7966 from the old core library. This was minor and easy split.
7968 * Created SILC Client Library (lib/silcclient) that includes
7969 implementation of the SILC client without user interface. This
7970 was major move from silc/ directory. The code has been changed
7971 so that it is transparent towards the user interface. The
7972 silc/ directory includes now the same user interface as before
7973 and it uses the new client library. Read lib/silcclient/README.
7974 Basicly, the client library performs everything else related
7975 to SILC except user interface handling. Also, configuration
7976 files are considered to be part of user interface and library
7977 does not handle them.
7979 This change also changed a lot of structures, function naming etc.
7980 Most important change was that SilcClientWindow object was
7981 renamed to SilcClientConnection in the client library. Created
7982 also new file lib/silcclient/ops.h. Also added new files
7983 silc/local_command.[ch] and silc/client_ops.[ch].
7985 All these changes were made to make it easier for user interface
7986 designers to create what ever user interface for the SILC client
7989 It is also expected that the server will be moved to lib
7990 directory as well and SILC Server Library will be created;
7991 sometimes in the future.
7993 * Removed Local commands from lib/silccore/silccommand.h as
7994 they are application specific and new client library does not
7995 handle any of those anymore.
7997 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7998 old client implementation in silc/.
8000 * Added support for callback functions in SILC_LOG_* macros.
8001 Application can now set its own callbacks that will be called
8002 instead of using the default functions that will always print
8003 the debug messages to stderr (or stdout). Also, debugging can
8004 now be disabled by setting silc_debug to FALSE and re-enabled by
8005 setting it to TRUE. Note, that logging will still work even
8006 if debugging is disabled.
8008 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8009 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8010 silc_log_reset_debug_callbacks.
8012 * To enable debugging in silc client one must give now -d
8013 option on command line.
8015 * Changed silc_schedule_init to automatically allocate task queues
8016 if they are not allocated before calling it.
8018 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8020 * Added GMP 3.1 into math library.
8022 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8024 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8025 a channel in SILC network. The packet is used by servers and
8026 routers to notify other routers that user has left a channel.
8027 This little feature was missing until now. Added the feature
8028 to protocol specification as well.
8030 Added functions: silc_server_send_remove_channel_user and
8031 silc_server_remove_channel_user into server.[ch].
8033 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8034 lib/silccore/silcpacket.h. However, they are not implemented
8037 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8039 * Fixed joining to a channel and sending channel messages
8040 between server and router. The channel message sending should
8041 now work inside a cell.
8043 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8045 * Fixed the private message sending between server and router.
8046 The private message sending should now work inside a cell.
8048 * Added silc_server_replace_id into server.[ch] to replace
8049 existing ID in the SILC network.
8051 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8052 and silc_idlist_replace_server_id into idlist.[ch] in server.
8054 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8056 * Fixed the server to server connections. Server can again now
8057 connect to router. Router to router connections probably does
8060 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8062 * Added dynamic protocol registering support. Now protocols can
8063 registered and unregistered on the fly. Patch by cras.
8065 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8067 * Added lib/contrib directory to hold routines that some platforms
8068 don't have but are needed by SILC.
8070 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8071 into lin/contrib to provide getopt() and getopt_long() for
8072 those who don't have it.
8074 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8076 * Added AWAY command to client. When away message is set and
8077 client receives a private message packet the client automatically
8078 replies to the sender with the away message.
8080 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8081 bug seemed to be the cause of recent problems when compiling
8084 * Added version detection support to SKE protocol specification
8085 and added the new changes to the SKE implementation as well.
8086 There were other minor changes in the SKE protocol as well.
8088 Many changes in lib/silcske/silcske.[ch] and in
8089 lib/silcske/payload.[ch].
8091 * Added ^U functionality, clear input line. Patch from cras.
8093 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8095 * Mainly small bugfixes on core library. Fixed some debugging
8096 logging and buffer overflow in silclog.c.
8098 * Updated config.sub and config.guess on the distribution tree.
8100 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8102 * Added command lagging support in server. Client may execute
8103 commands now only once in two seconds.
8105 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8107 * Optimized packet reception. MAC computation and checking is now
8108 also more optimized. A lot previously duplicated code is now
8109 used as generic by both client and server.
8111 * Fixed key pair generation in clientutil.c
8113 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8115 * Added into lib/silccore/silcbufutil.[ch] new function;
8116 silc_buffer_realloc.
8118 * Moved generic packet sending/encryption functions to
8119 lib/silccore/silcpacket.[ch] from client and server. Some
8120 rewriting of the functions.
8122 * Moved all generic packet reception/decryption functions to
8123 lib/silccore/silcpacket.[ch] from client and server. The
8124 packet processing is now much cleaner in both client and server.
8125 These were major changes in both client and server.
8127 * Created many common functions in server to do packet sending.
8128 Previously code were duplicated a lot, this has been removed
8131 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8133 * Rewrote major parts of the ID cache system. Don't know
8134 whether it is better now or not but at least the API is more
8137 * Major rewrite on ID cache stuff on client because of the ID
8138 cache API changes. Added idlist.c to client.
8140 * Also major rewrite on ID cache stuff on server as well.
8141 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8142 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8143 in hand, instead they are all put into the ID cache system now.
8144 All server_idlist_* routines uses ID cache now instead of
8145 traversing its own lists (those lists does not exist anymore).
8146 SilcIDList though still exists. Also, SilcXXXEntry's are
8149 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8151 * Finally made the SKE implementation compliant to the protocol
8152 specification. All mp integers are now binary encoded as
8153 opposed being HEX encoded.
8155 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8158 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8159 functions: silc_[encode/decode]_pem. Also added function
8160 silc_encode_pem_file to PEM encode with newlines ('\n') for
8163 * SILC public keys are now encoded either PEM or binary. Same
8164 option is for private keys as well. By default private keys
8165 are binary encoded and public keys PEM encoded. Silly HEX
8166 encoding were removed.
8168 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8169 function to create fingerprints.
8171 * Fixed a bug in SHA1; does not change the original data anymore.
8173 * Partly implemented INFO command on client and server side.
8174 Fixed CLEAR command. Changes to SERVER command; show current
8175 server(s) when giving command without arguments. Added
8176 VERSION command to client.
8178 * Added check to server that unregistered connections cannot
8179 execute commands (unless it is specificly allowed).
8181 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8183 * Fixed screen refresh.
8185 * Fixed channel joining bug from client. On some circumstances
8186 client tried to join to a channel it had already joined.
8188 * Added public key verification process into client's protocol.c.
8189 The client now verifies the public key from user and saves
8190 it into ~./silc/serverkeys/ directory.
8192 Added into: clientutil.[ch]: silc_client_verify_server_key.
8194 * Changed SKE protocol's silc_ske_initiator_finish function
8195 to accept callback function that verifies the received public
8196 key. Removed old silc_ske_verify_public_key function.
8198 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8200 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8201 silc_pkcs_private_key[_data]_set.
8203 * Made the password and public authentication more cleaner in
8204 server's protocol.c.
8206 * Removed historic and obsolete protocol `channel_auth' from
8207 both client and server.
8209 * Removed wrong way of sending command status messages from
8210 server to client in server's command.c. The old way violated
8211 protocol specification.
8213 Changes to silccore/silccommand.[ch]: removed
8214 silc_command_encode_status_payload -> not needed anymore,
8215 changed silc_command_encode_payload_va to accept extra
8216 argument on variable argument list. The argument type must
8217 now be provided to the function. Also, added new function:
8218 silc_command_encode_reply_payload_va which is same as
8219 normal command_encode_payload_va except command status type
8220 is provided as extra argument.
8222 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8224 * Added ~./silc directory handling. The directory includes the
8225 public and private keys for the client.
8227 Added silc_client_check_silc_dir, silc_client_create_identifier
8228 and silc_client_load_keys.
8230 * Implemented SILC protocol compliant public key. Added public
8231 and private key saving to and loading from files.
8233 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8234 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8235 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8236 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8237 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8239 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8240 silc_pkcs_load_[public/private]_key.
8242 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8244 * Added silc_server_get_route (route.[ch]) to get connection
8245 data for the fastest route for given ID.
8247 * Implemented INVITE command on client and server. The command
8248 were re-defined in the SILC Protocol Specification and the
8249 implementation now complies with the specification.
8251 * Implemented PING command on client and server.
8253 * Implemented NAMES command on client and server. The server side
8254 supports currently only normal server not router server yet.
8255 Some changes to NAMES definition in SILC protocol specification.
8257 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8259 * Implemented LEAVE command on client and server.
8261 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8262 again. This change was made to the protocol as well. Server
8263 should not violate the protocol specification anymore.
8265 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8267 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8268 was tested. SOCKS4 was not but should work anyway.
