19 or user mode changes the watcher will be notified of this
20 change. Added SILC_COMMAND_WATCH command, added new
21 notify type SILC_NOTIFY_TYPE_WATCH to deliver the watch
22 notifications. Updated the protocol specs and implemented
23 this to library, client and server. Protocol TODO #21.

43 * Added SilcStatus argument to `command' client operation
44 to return the error status when command sending fails
45 locally. Changed all command in client library to return
46 correct command status. Affected files are
47 lib/silcclient/command.c, lib/silcclient/silcclient.h and
48 irssi/src/silc/core/client_ops.c.

62 written in a root-owned directory.
64 Tue Apr 16 09:34:40 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
66 * Defined that channel message to unknown Channel ID must
67 cause SILC_NOTIFY_TYPE_ERROR notify message to the sender.
68 Updated the protocol specs and the code in server. The
69 affected file is silcd/packet_receive.c.
71 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
73 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
74 that it is used to send error notifys if error occurs during
75 some SILC packet processing, except commands. The error
76 types are same as for command reply types. Defined that
77 if private message is sent to unknown Client ID the error
78 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
79 Updated the protocol specs and code. Affected files are
80 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
81 lib/silcclient/client_notify.c, silcd/packet_receive.c,

83 SilcCommandStatus to SilcStatus.
85 * Defined the use of extra WHOIS attributes in WHOIS command.
86 The <Requested Attributes> (defined in a separate document)
87 can be used to request additional information about user
88 not returned by standard WHOIS command. Defined that server
89 can send WHOIS command directly to client. Client provides
90 the requested attributes to the server. Updated the protocol
91 specs. Protocol TODO #4. Implementation is not done yet
94 * Renamed function silc_client_command_status_message to
95 silc_client_status_message. Affected files are

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

130 and secret channels too. Updated protocol specs and the
131 code in server. Affected file silcd/command.c.
133 * Defined <channel user mode list> argument to WHOIS command
134 reply for returning user modes on the channels. The
135 channel list now doesn't include the user mode anymore but the
136 actual channel mode. Updated protocol specs and the code in
137 client and server. Affected files are silcd/command_reply.c,
138 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
139 and lib/silcclient/command_reply.c.
141 * Save the channels list in WHOIS command reply in normal server
142 so that WHOIS always shows joined channels also in normal
143 server and not just on router. Affected file is
144 silcd/command_reply.c.
146 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

156 mask to the client. Updated protocol specs and the server.
157 Affected file is silcd/command.c.
159 * Added SILC session detachment/resuming support. It is possible
160 to detach by closing the network connection and then re-connect
161 and resume to the old client session. Added DETACHED user
162 mode that server will set for detached client. Added new
163 packet RESUME_CLIENT which is used to perform the resuming
164 process. Added DETACH command. Updated the protocol specs,

172 mask to the client. Updated protocol specs and the server.
173 Affected file is silcd/command.c.
175 * Changed the Killer's Client ID in KILLED notify to be just
176 any ID payload since router server is allowed to kill as well.
177 Updated protocol specs, client libary and server. Affected
178 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
179 and irssi/src/silc/core/client_ops.c.

194 may set to itself to tell server not send channel messages.
195 Other packets such as channel key packets are still sent.
196 Protocol TODO #23. Updated the protocol specs, client and
197 server. Affected files are lib/silccore/silcmode.h,
198 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,

202 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
204 * Redefined the Status Payload to include now two 8 bit fields,
205 instead of one 16 bit field. This now makes it possible to
206 send list of errors. Updated the protocol specs and the code
207 in core library, client library and server. Protocol TODO #1.
208 Affected files are lib/silccore/silccommand.[ch],
209 lib/silcclient/command_reply.[ch], silcd/command.c,
210 silcd/command_reply.c and silcd/packet_receive.[ch].
212 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
214 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
215 must be handled by the application and should tell the application
216 that an error message was already printed, and it should print the
217 config coords (line, filename, ...). Affected files are
218 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
220 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the

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

281 UTF-8 encoded, defined that version string MUST be US-ASCII
282 encoded, defined that passphrases sent in connection
283 authentication protocol MUST be UTF-8 encoded. Implemented
284 these to the client and server. Defined also that other
285 passphrases sent in the protocol MUST be UTF-8 encoded.
286 Affected files are lib/silcske/silcske.c,
287 lib/silcclient/protocol.c, silcd/protocol.c,
288 silcd/serverconfig.c, and lib/silccore/silcauth.c.
290 * Changed the silc_client_close_connection interface to not
291 need the SilcSocketConnection which should not be visible
292 to application. Affected files are lib/silcclient/client.c
293 and lib/silcclient/silcclient.h.
295 * Rewrote the text for Private Message Key Payload in the
296 protocol specification. Protocol TODO #11.
298 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
300 * Upgraded the protocol version to 1.1, updated protocol specs
303 * Added the nickname as new argument to NICK_CHANGE notify and

313 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
314 The killer's client entry is now returned to application in
315 the `notify' client operation.
317 * Fixed the Max Argument fields that had too large value set
318 in the protocol specs. Protocol TODO #14.
320 * Added the LEAVE command reply to return the ID of parted
321 channel. Updated protocol specs and implemented it to the
322 client and server. Protocol TODO #15. Affected files are
323 silcd/command.c, lib/silcclient/command_reply.c. The channel
324 entry is now returned to application in the `command_reply'

328 and in server to use the silc_parse_version_string. Affected
329 files are lib/silcclient/protocol.c, silcd/protocol.c.
331 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
332 commands that was missing it, and updated protocol specs and
333 the server implementation. Protocol TODO #10. The affected
334 file is silcd/command.c.
336 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
337 generic reply to a generic request (REQUEST flag), and
338 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
339 way. A draft-riikonen-silc-flags-payloads-00.txt is written
340 to define the payload for DATA flag. Added the flags to
341 the implementation. Protocol TODO #9. Affected file is
342 lib/silccore/silcchannel.h.
344 Changed the client library to return the message length
345 to application as well in the channel_message and private_message
346 client operations. Affected files are
347 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,

349 and lib/silcclient/client_ops_example.c.
351 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
352 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
353 the channel. Updated protocol specs and impelemented this
354 to client and server. Protocol TODO #6. Affected files are
355 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

358 Added new options m and M to CMODE command in Irssi SILC
359 client to set these modes.
361 * Deprecated all administrative commands from SILC protocol
362 since they are highly implementation specific commands.
363 Updated protocol specs. Moved the old commands in
364 implementations to private range of command types. Affected
365 files are silcd/command.c, lib/silcclient/command.c and
366 lib/silcclient/command_reply.c. Protocol TODO #8.

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

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

467 public/private key and removed further checks in the code.
468 Affected files are silcd/serverconfig.[ch], server.c.
470 * Moved functions silc_server_drop() and silc_server_daemonise()
471 from server.c to silcd.c since they are stricly related to
472 the application activity.
474 * Reverted a small part of the automatic ref/unref since
475 it caused a double unref in some situations. Affected
476 files are silcd/silcd.[ch], server.c, serverconfig.c.

483 address. Affected file lib/silcutil/silcnet.c.
485 * Fixed the notify relaying to client. The HMAC to be used
486 with relayed packets ws wrong and caused decryption failure
487 at the client end. Affected file is silcd/packet_receive.c.
489 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
491 * Created new branch silc_protocol_1_0_branch.
493 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
495 * Changed the silc_server_config_* routines to be SilcServer
496 independent. They are now officially application specific code
497 and not part of generic server implementation. Affected files
498 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
500 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>

507 * Fixed the silc_log_quick handling in the logging routines.
508 It didn't log quickly when it was TRUE. Affected file is
509 lib/silcutil/silclog.c. Also the flush delay was set even
510 if it was 0 in config file. Affected file is
511 silcd/serverconfig.c.
513 * Added support for changing key pair of the server in rehash.
514 Affected file silcd/server.c.
516 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
518 * Fixed the TOPIC_SET notify to not cras. It changed the topic
519 too early, before getting the channel entry. Affected file
520 is silcd/packet_receive.c.
522 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
524 * Added functions silc_server_config_[ref/unref], these are used
525 to prevent that the config object is destroyed.
527 No longer directly affect global variables silc_log_quick and
528 silc_log_delay, they are first cached inside the config object
529 and then applied with silc_server_config_setlogfiles().
531 silc_server_config_set_defaults() is now internal to
532 serverconfig.c, there are no reasons to show this internal stuff
535 Affected files are silcd/serverconfig.[ch].
537 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
538 fprintf's to stderr, since some code may be executed again after
539 the server went into the background. Affected files are
542 * Added rehash support. Added function silc_server_rehash() that
543 will perform all the basic tasks of the rehashing procedure.
545 * Added command line option `-x, --hexdump'. This will enable the
546 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
547 The option `--hexdump' implies `--debug'.
549 * Fixed a bad bug in the logging APIs (silcutil library) where
550 the application would crash after calling silc_log_reset_all().
552 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
554 * Fixed the KICKED notify handling in client library to
555 correctly remove the channel and all entries from the
556 channel when I was kicked. This bug crashed the client.
558 Fixed yet another but in KICKED notify handling to remove
559 the kicked client correctly from the channel.
561 Affected file is lib/silcclient/client_notify.c.
563 * Fixed a minor bug in looking up correct client entry
564 in KICKED notify in server. Affected file is
565 silcd/packet_receive.c.
567 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
568 sources correctly to distribution. Fixes --with-gmp option.
570 * Removed the manual rehashing from ID Cache, and changed it
571 to use the SILC Hash Table's auto rehash feature. Affected
572 file is lib/silccore/silcidcache.c.
574 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
576 * Fixed a bug in the silc_client_nickname_format function that
577 handles the multiple same nickname formatting. Two clients
578 with same nickname caused problems after the first one left
579 and rejoined. It didn't format the nickname correctly.
580 Affected file is lib/silcclient/idlist.c.
582 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
584 * Don't change the topic if olod topic is same as new one.
585 Affected file is silcd/packet_receive.c.
587 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
589 * Added cross-reference support to the SILC Documentation
590 generator. All types across all HTML files are now cross-
591 referenced. Affected files util/robodoc/generator.c and
592 scripts/silcdoc/silcdoc.
594 * Added file lib/silcutil/silctypes.h to include all the
595 arithmetic type definitions and some macros. Removed
596 includes/bitmove.h and moved macros to silctypes.h.
598 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
600 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
602 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
604 * Added `type' argument to silc_id_payload_parse_id function which
605 now returns the type of the ID to the sent pointer. Affected
606 file is lib/silccore/silcid.[ch].
608 * Added check for CMODE_CHANGE notify type that mode change is
609 allowed by the sender. Affected file silcd/packet_receive.c.
611 * Added check for CUMODE_CHANGE notify type that mode change is
612 allowed by the sender. Affected file silcd/packet_receive.c.
613 Added the ID type as CUMODE_CHANGE notify type as argument
614 to the `notify' client operation. Affected files are
615 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
617 * Added function silc_client_add_server to the client library.
618 Added support for resolving also channel and server info when
619 received unknown entity in notify packet. Affected files are
620 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
622 * Added function silc_command_get_status to return the command
623 status from the command reply's argument payload. Affected files
624 are lib/silccore/silccommand.[ch].
626 * Added check for KICKED notify type that the kicking is
627 allowed by the client. Affected file silcd/packet_receive.c.
629 * Created function silc_get_input which can be used to get input
630 (echo on or off) from user on command line. Affected files are
631 lib/silcutil/silcutil.[ch].
633 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
635 * Optimized silc_server_packet_relay_to_channel function.
636 Added new function silc_channel_message_payload_encrypt which
637 can be called directly if channel message payload needs to
638 be encrypted and is already encoded (no need to call _encode
639 function). Packet relaying is now done by router without any
640 extra memory allocations. Affected files are
641 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
644 * Fixed the INVITE notify handling. It took wrong arguments
645 as invite list and invite delete. Affected file is
646 silcd/packet_receive.c.
648 * Added check for TOPIC_SET notify type that the topic change is
649 allowed by the client. Affected file silcd/packet_receive.c.
651 * Added check for INVITE notify type that inviting is allowed by
652 the client. Affected file silcd/packet_receive.c.
654 * Changed the silc_server_client_on_channel to return the
655 SilcChannelClientEntry as well. Moved the function
656 silc_server_check_cmode_rights to server_util.[ch].
657 Affected files are silcd/server_util.[ch], silcd/command.c.
659 * Added function silc_server_check_umode_rights to check whether
660 changing client's user mode is allowed. Added check for
661 UMODE_CHANGE notify type that the umode change is allowed
662 by the client. Affected files are silcd/server_util.[ch],
663 silcd/packet_receive.c and silcd/command.c.
665 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
667 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
668 ID length. It ignored that ID can be IPv6 based as well.
669 Affected file lib/silccore/silcpacket.h.
671 * Fixed the silc_id_id2str and silc_id_str2id to take the
672 IPv6 address offset's into consideration. Affecte file is
673 lib/silccore/silcid.c.
675 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
677 * Fixed the internal Unix scheduler functions to check for
678 NULL context they may receive. The affected file is
679 lib/silcutil/unix/silcunixschedule.c.
681 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
683 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
684 can specify different directory with --home command line
685 parameter. Affected files irssi/src/silc/core/client_ops.c,
688 * SILC-specific commands aren't now executed if the active server
689 isn't of SILC-type, so there won't be problems with having
690 IRC and SILC protocol support in same client. Affected files
691 irssi/src/silc/core/silc-channels.c, silc-servers.c,
694 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
696 * Improved the signal support in SILC Schedule. Added new
697 function silc_schedule_signal_call which is used by application
698 to mark a signal to be called. It is now safe to perform
699 any kind of tasks in signal callbacks since it is guaranteed
700 that the application specified signal callback is called
701 after the signal is over. Affected files are
702 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
704 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
706 * Added `name' field to SilcChannelPrivateKey to represent
707 application given name for the key. Moved also the context from
708 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
709 Added the `name' argument also to the function
710 silc_client_add_channel_private_key.
712 Added function silc_client_current_channel_private_key to set the
713 current channel private key in use.
715 Added "change" command to KEY command which can be used to change
716 the current channel private key. Bound the command also to
719 Also affected files lib/silcclient/client_channel.c,
720 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
722 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
724 * Added silc_rng_get_byte_fast function in to the
725 lib/silccrypt/silcrng.[ch].
727 * Changed the interface of silc_packet_assemble and the
728 silc_packet_send_prepare. If silc_packet_assmble is now
729 called the application does not call silc_packet_send_prepare
730 because the library will call it automatically. These
731 interfaces now also return a reference to the outgoing buffer
732 which includes the assembled packet, which the application can
733 use to encrypt the packet.
735 Affected files are lib/silccore/silcpacket.[ch],
736 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
737 silcd/packet_send.c, server_backup.c and packet_receive.c.
739 * Fixed a packet sending bug on very high load, where outgoing
740 packet queue wasn't handled correctly and packets got corrupted.
741 Affected files are lib/silcutil/*/silc*sockconn.c,
742 lib/silcclient/client.c and silcd/server.c.
744 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
746 * Added macro SILC_PACKET_DATALEN which can be used during
747 packet assembling to check whether the data to be added to
748 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
749 len is truncated until it fits it.
751 Added checks for maximum length of channel message payload and
752 private message payload also.
754 Added checks for maximum packet length in server and in
757 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
758 lib/silcclient/client.c, lib/silccore/silcchannel.c and
759 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
760 lib/silcclient/client_prvmsg.c.
762 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
764 * Added silc_server_packet_queue_purge call to the
765 silc_server_disconnect_remote to assure that all data in the
766 queue before disconnecting is sent to the network. Affected
769 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
771 * Added the deleting of server's own ID cache entry to the
772 silc_server_free function. Free also everything else that
773 has been allocated in silc_server_init. The affected file
776 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
778 * Added functions silc_parse_version_string, silc_version_to_num,
779 and silc_ske_parse_version to parse SILC protocol style version
780 strings. Affected files lib/silcutil/silcutil.[ch] and
781 lib/silcske/silcske.[ch].
783 * Added new configuration params: version_protocol, version_software
784 and version_software_vendor to specify what version the remote
785 host must at least be to be able to connect to server. The vendor
786 string can be regex matched too. Added new function
787 silc_server_connection_allowed to check maximum number of allowed
788 connections, and allowed versions for incoming connections.
789 Affected files are silcd/server.c, server_util.[ch] and
792 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
794 * Added preliminary support for signals in scheduler. The
795 signals we care about are now blocked always when the scheduler
796 is locked. This way we can synchronise the use of signal with
797 scheduler. It is guaranteed that when signal occurs the scheduler
798 is not locked, and thus new tasks can be safely added to the
801 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
802 to silc_schedule_internal_init and silc_schedule_internal_uninit.
803 Added new platform specific routines
804 silc_schedule_internal_signals_[un]block and
805 silc_schedule_internal_signal_[un]register.
807 Added new functions to SILC Schedule API:
808 silc_schedule_signal_[un]register. Each signal that application
809 is going to use should be registered to the scheduler.
811 Affected files are lib/silcutil/silcschedule.[ch],
812 lib/silcutil/*/silc*schedule.c.
814 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
816 * Check for unauthenticated client and server in the
817 silc_server_new_client and silc_server_new_server functions.
818 Affected file silcd/packet_receive.c.
820 * Added function silc_string_is_ascii to check whether given
821 string is 7-bit ASCII string. Affected files are
822 lib/silcutil/silcutil.[ch].
824 * Added function silc_id_is_valid_server_id into the
825 silcd/serverid.c and added checking for valid Server ID's in
826 silc_server_new_server. The Server ID must always be based
827 on the server's public IP address.
829 * Added logging of DISCONNECT packet message in the server.
830 Affected file silcd/server.c.
832 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
834 * Changed all library interfaces that use Global RNG to also
835 accept SilcRng as argument. Affected files are
836 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
837 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
838 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
839 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
842 * Added function silc_pkcs_generate_key to the
843 lib/silccrypt/silcpkcs.[ch] for applications so that they
844 don't need to do pkcs->pkcs->init calls anymore.
846 * Remove SilcSocketConnection from the SFTP API since it really
847 wasn't needed there. The application has the information
848 saved in its contexts anyway and the SFTP layer doesn't need
849 know about it. Affected files lib/silcsft/silcsftp.h and
850 lib/silcsftp/sftp_[server/client].c.
852 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
853 The SilcSimContext is not SilcSim.
855 * Fixed possible buffer overflows in silc_id_render in the
856 lib/silcutil/silcutil.c.
858 * On EPOC the global crypto module lists are not used at all
859 in the crypto library. Added support for using the constant
860 algorithm list on EPOC. Affected files are
861 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
864 * Fixed the handling of third parameter of KICKED notify, since
865 it was mistakenly updated to SILC Protocol 1.0 even though it
866 is to be included in 1.1. Since it is not in 1.0 it is not
867 mandatory, and this fix now handles it only if it is provided,
868 and it is not error if it is not provided. Affected file
869 lib/silcclient/client_notify.c.
871 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
873 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
874 client. Affected file irssi/src/silc/core/client_ops.c.
876 * Merged with Irssi 0.8.4 from irssi.org CVS.
878 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
880 * Check for valid socket connection in client entries before
881 sending any messages. Fixes a crash, but doesn't fix some
882 other underlaying bug that is lurking there. Affected
883 file silcd/packet_send.c.
885 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
887 * $usermode, $cumode and $cumode_space expandos shouldn't do
888 anything with non-SILC server records. Affected file
889 irssi/src/silc/core/silc-expandos.c
891 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
893 * Fixed the silc_net_check_[host/local]_by_sock to support
894 IPv6 bound sockets as well. Now they can return IPv6 addresses
895 as well. Affected file lib/silcutil/silcnet.c.
897 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
898 Affected lib/silcutil/unix/silcunixnet.c.
900 * Fixed ID rendering (at least on some platforms, not NetBSD)
901 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
903 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
905 * Added silc_hash_public_key and silc_hash_public_key_compare
906 functions to be used with SilcHashTable. They can be used to
907 hash public keys and compare public keys in hash table. Affected
908 file lib/silcutil/silcutil.[ch].
910 * Added support for specifying multiple public keys for Client
911 connection section in server configuration file. This makes it
912 possible to accept multiple public keys from same host, or to
913 make a section that accepts any incoming host, and have the
914 accepted public keys listed in the section.
916 Added functions silc_sever_[find/get]_public_key, added the
917 support for this actually to all connection sections but only
918 the Client section is currently allowed to specify multiple
921 Affected files are silcd/server.c, server_internal.h,
922 command.c, protocol.c, server_util.[ch], packet_receive.c.
924 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
926 * Merged Irssi 0.8.2 from irssi.org CVS.
928 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
930 * If silc_debug is TRUE, also output standard logging messages
931 to stderr with the debug output.
933 Made silc_log_reset_all() flushing all channels before returning.
934 Also fixed some documentation typos.
936 Affected files are lib/silcutil/silclog.[ch].
938 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
940 * Fixed the server to check correctly the amount of connections
941 from single host, by checking also the type of the connection.
942 Fixed also the comparison of number of connections and number
943 of allowed connections. Affected files are silcd/server.c,
946 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
948 * Fixed the USERS command reply to save the user's mode on the
949 channel as well. Fixed JOIN command reply to check whether a
950 client is on channel already and not join it twice. Affected
951 file lib/silcclient/command_reply.c.
953 * Added new file silc-expandos.c into irssi/silc/core/ to return
954 various stuff for various signal for the statusbar etc. updating.
955 Now Irssi SILC client prints channel user modes etc. on the
958 * The user mode (like server/router operator changes) is now shown
959 on the Irssi SILC client's statusbar. The affected files are
960 irssi/src/silc/core/client_ops.c, silc-expandos.c.
962 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
964 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
965 to SILC_SCHEDULE_[UN]LOCK macros.
967 * Added more error printing to logs in server code. Affected
968 files silcd/server.c and silcd/protocol.c.
970 * Fixed -S option parsing in Irssi SILC Client. Affected file
971 irssi/src/silc/core/silc-core.c.
973 * Added silc_buffer_alloc_size function. Affected file is
974 lib/silcutil/silcbuffer.h.
976 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
978 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
979 constants. Affected files in
980 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
983 * Changed the internal SFTP Memory FS table to const. Affected
984 file lib/silcsftp/sftp_fs_memory.c.
986 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
988 * Fixed the buffer formatting and unformatting routines to
989 check the size of 64 bits types with sizeof(). Affected
990 file is lib/silcutil/silcbuffmt.c.
992 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
994 * Removed 0.6.x backwards support.
996 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
998 * Changed all integer type names:
999 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1000 to avoid collisions with other libraries using same type names
1003 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1005 * Added `prefer_ipv6' argument to the functions
1006 silc_net_gethostbyname[_async]. If it is TRUE it will return
1007 IPv6 address over IPv4. If FALSE IPv4 address is returned
1008 even if IPv6 address was found. Affected files
1009 lib/silcutil/silcnet.[ch].
1011 * Added support silc_net_create_connection[_async] to fallback
1012 to IPv4 address if IPv6 address could not be used (like if
1013 it doesn't work on a specific system). Affected file in
1014 lib/silcutil/unix/silcunixnet.c.
1016 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1018 * Added silc_schedule_reinit function to do the enlarging
1019 of the max tasks handling capabilities of the scheduler.
1020 Affected files lib/silcutil/silcschedule.[ch].
1022 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1024 * Added automatic extern "C" { ... } for C++ compilers so the
1025 application does not need to define them. Affected file
1026 includes/silcincludes.h.
1028 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1029 old name went against naming convention. Applications now
1030 include "silcclient.h" instead of "clientlibincludes.h".
1031 Removed includes/clientlibincludes.h, it is redundant now.
1033 * Renamed includes/version.h to silcversion.h.
1035 * Added really preliminary support for OS/2 into the util
1036 library. Only thread & mutex API is implemented, others
1037 are still to be implemented. Created the lib/silcutil/os2/
1038 directory. Created also file includes/silcos2.h.

1071 * Added `user_count' to the SilcChannelEntry which now tells the
1072 number of users on the channel. The user count is now saved
1073 in normal server of global channels as well. Affected files
1074 silcd/server.c, idlist.h, packet_receive.c and command.c.
1076 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1077 include file utility functions.

1093 the SKE interface a bit.
1095 * Fixed padding problem in PKCS#1. The padding was not actually
1096 random since the random number generator was used incorrectly.
1097 This security bug affects only when encrypting with PKCS#1, and
1098 it is not currently used at all in SILC. SILC only use signing
1099 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1159 is now done in silc_core_init() which also fixes autoconnecting
1162 Affected files irssi/src/silc/core/silc-core.c,
1163 irssi/src/fe-text/silc.c.
1165 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1167 * Added new configuration options and blocks:
1168 keepalive_secs, reconnect_count, reconnect_interval,
1169 reconnect_interval_max, reconnect_keep_trying and
1170 require_reverser_lookup. Added ConnectionParam block, and
1171 implemented the connection parameters when connecting as
1172 initiator and when accepting connections as responder.

1184 the connection configuration object from the SilcServerConnection
1185 object instead of finding it during the connecting phase.
1186 Added the configuration object to SilcServerConnection struct.
1187 Affected files silcd/server_internal.h, server.c.
1189 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1191 * Add the client on channel after it was resolved at the
1192 channel message receiving, and it was not already on the
1193 channel. Affected file lib/silcclient/client_channel.c.
1195 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1211 authentication to be set at the same time.
1213 Added `prefer_passphrase_auth' setting in config file which
1214 can be used to set to prefer passwd auth if both passwd and
1215 public key is set. If not set, public key is preferred.
1216 This has effect only when being initiator (responder will try
1219 Added support for authentication with passphrase and public key
1220 at the same time. The passphrase is tried first always since
1221 it is faster to check.
1223 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1225 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1227 * Merged the new SILC Config library, with the server parsing

1271 * Fixed the file transfer's key agreement payload to include
1272 zero port also if the hostname is NULL because it could not
1275 Call file transfer monitor callback now also if error occurs
1276 during key agreement protocol.
1278 Changed the silc_client_file_send interface to return the
1279 SilcClientFileError instead of session id. The session ID
1280 is returned into pointer provided as argument.
1282 Check that the file exists locally before sending the
1283 file transfer request at all.
1285 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1287 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1288 error than can occur while key agreement protocol. Affected
1289 file lib/silcclient/silcapi.h.

1297 file lib/silcutil/silclog.c.
1299 * Fixed the channel message payload decryption in the function
1300 silc_channel_message_payload_decrypt to not modify the original
1301 buffer before it is verified that the message decrypted
1302 correctly. Otherwise, next time it is called with correct
1303 channel key it won't encrypt since the payload is corrupted.
1304 Affected file lib/silccore/silcchannel.c.
1306 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1318 * Fixed a bug in hash table internal routine for traversing
1319 the table with foreach callback. The current entry may
1320 become invalid in the callback but it was referenced after
1321 the callback returned.
1323 Do not allow auto rehashing of hash table during the
1324 silc_hash_table_foreach operation, for same reasons as it is
1325 not allowed for SilcHashTableList. Affected files are
1326 lib/silcutil/silchashtable.[ch].
1328 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1334 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1336 * Fixed private message handling. It used some old code that
1337 caused the client to crash. Affecte file is
1338 lib/silcclient/client_prvmsg.c.
1340 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1342 * Added function silc_client_add_channel,
1343 silc_client_replace_channel_id, and removed functions
1344 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1345 from client library.
1347 * Added cross reference of the joined channels to the
1348 SilcClientEntry, and changed the SilcChannelEntry's
1349 users list to SilcHashTable. The affected files are
1350 lib/silcclient/idlist.[ch].
1352 * Fixed a bug in hash table tarversing. While the hash table
1353 is traversed with SilcHashTableList the table must not be
1354 rehashed. It is now guaranteed that auto rehashable tables
1355 are not rehashed while tarversing the list. Also defined that
1356 silc_hash_table_rehash must not be called while tarversing
1357 the table. Added function silc_hash_table_list_reset that must
1358 be called after the tarversing is over. The affected files are
1359 lib/silcutil/silchashtable.[ch].
1361 * Changed all hash table traversing to call the new
1362 silc_hash_table_list_reset in server and in client library.
1364 * Added function silc_client_on_channel to return the
1365 SilcChannelUser entry if the specified client entry is joined
1366 on the specified channel. This is exported to application as
1367 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1369 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1371 * Fixed founder regaining problem with JOIN command on normal
1372 server. The notify for mode change must be sent always and
1373 not only if !cmd->pending. Affected file silcd/command.c.
1375 * Fixed the WHOWAS command's reply sending to support the
1376 lists correctly. Affected file silcd/command.c.
1378 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1380 * When sending JOIN command to router for processing the
1381 sender's old command identifier was not saved back to the
1382 sender's command context, fixed now. The affected file is
1385 * Create the key in JOIN command of the router did not return
1386 the channel key, added check for this. Affected file is
1389 * Fixed a channel ID update bug in JOIN command reply. Do
1390 not directly upgrade the ID but call the function
1391 silc_idlist_replace_channel_id if the ID was changed.
1392 Affected file silcd/command_reply.c.
1394 * Fixed memory leaks from command calling if it would fail.
1395 Affected file silcd/command.c.

1407 * Removed TRQ from lib/trq, not needed anymore.
1409 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1410 with server connections. Later this will be configurable
1411 in config file after new config file is done. Affected file
1414 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1416 * Fixed a crash in server related to channel announcements.
1417 Affected file silcd/server.c.
1419 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1421 * Fixed memory leaks in silc_server_create_new_channel*
1422 functions. Affected file silcd/server.c.
1424 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1425 which ID was changed. This way the router will send the
1426 user list for the channel again, and server won't be in
1427 desync in some rare circumstances. Affected file is
1428 silcd/packet_receive.c.
1430 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1445 file for application programmers to quickly start using
1446 the SilcClientOperation functions in their application.
1447 Updated the lib/silcclient/README as well to tell about this
1448 nice file made available.
1450 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1452 * Call silc_server_remove_from_channels when removing client
1453 entry when NO_SUCH_CLIENT_ID was received. Affected file
1454 is silcd/command_reply.c.

1458 * Added server & router operator statistics updating. Affected
1459 file silcd/packet_receive.c and silcd/command.c.
1461 * Fixed the SERVER_SIGNOFF notify handling on normal server
1462 not to save the history information for clients. Same was
1463 fixed earlier in remove_clients_by_server function, but not
1464 here. Affected file silcd/packet_receive.c.
1466 * Raised the default connection-retry count from 4 to 7 in
1467 server. Affected file silcd/server.h.

1477 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1479 * Fixed the NICK command to always give the unformatted
1480 nickname to the one giving the NICK command. If unformatted
1481 nickname is cached already it will be formatted and the
1482 local entry will always get the unformatted nickname.
1483 Affected file lib/silcclient/idlist.c.
1485 * Fixed some double frees from client library commands.
1486 Affected file is lib/silcclient/command.c.
1488 * Fixed CUMODE command in server to assure that no one can
1489 change founder's mode than the founder itself, there was a
1490 little bug. Affected file silcd/command.c.
1492 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1494 * Removed the SilcClientCommandDestructor from the client
1495 libary, it is not needed anymore. Affected files are
1496 lib/silcclient/silcapi.h, command[_reply].[ch],
1497 client_notify, idlist.c.
1499 * Fixed GETKEY command to first resolve client, and then
1500 resolve the server only if the client was not found, instead
1501 of resolving both at the same time. Affected file is
1502 lib/silcclient/command.c.
1504 * Added silc_client_start_key_exchange_cb and lookup the
1505 remote hostname and IP address before starting the key
1506 exchange with server. The affected file is
1507 lib/silcclient/client.c.
1509 * The server's public key is now saved using the IP address
1510 of the server and not the servername for the filename.
1511 The hostname public key filename is checked as an fall back
1512 method if the IP address based filename is not found.
1514 Fixed the GETKEY command to save the fetched server key
1515 in correct filename.
1517 Print the remote server's hostname now when new key is
1518 received during connection process. Affected file is
1519 irssi/src/silc/core/client_ops.c.
1521 * Return always our own public key to the client if it asks
1522 for it with GETKEY command. Affected file silcd/command.c.
1524 * Removed the use_auto_addr variable from default config
1525 file since it was in wrong section. Affected file is
1528 * Fixed TOPIC_CHANGE notification to not route it when it
1529 was sent using silc_server_send_notify_to_channel function.
1530 Affected file silcd/command.c.
1532 * Fixed silc_server_send_notify_kicked to send the kicker's
1533 Client ID also, it was missing. Affected files are
1534 silcd/command.c, silcd/packet_send.[ch].
1536 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1538 * Do not save client history information in SERVER_SIGNOFF.
1539 Fixes the bug in normal server that it does not detect
1540 the client becoming valid after the server becomes back
1541 online. Affected file silcd/server_util.c.
1543 * Added `sock_error' field into the SilcSocketConnection
1544 context. When error occurs during socket operation (read
1545 or write) the error is saved. Added also new function
1546 silc_socket_get_error to return human readable socket error
1547 message. Affected files are lib/silcutil/silcsockconn.[ch],
1548 lib/silcutil/unix/silcunixsockconn.c, and
1549 lib/silcutil/win32/silcwin32sockconn.c.
1551 * The server now prints the socket error message in the
1552 signoff for client. Affected file silcd/server.c.
1554 * Fixed the `created' channel information sending from router
1555 to server in JOIN command. Checks now whether the channel
1556 really was created or not and set it according that.
1558 Fixed the JOIN command to use the client entry's current
1559 ID during the joining procedure instead of the one it sent
1560 in the command (it is checked though), since it can change
1561 between the packet processing and command processing, and
1562 would just case unnecessary pain in the client end. Affected
1563 file silcd/command.c.
1565 * Fixed a channel key payload sending to use correct channel
1566 ID when the server was forced to change the channel's ID by
1567 router. Router sent the key payload with the old Channel ID.
1568 Affected file silcd/packet_receive.c.
1570 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1572 * Call silc_server_save_channel_key only if the key payload
1573 was provided in the JOIN command's command reply. Affected
1574 file silcd/command_reply.c.
1576 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1578 * Fixed silc_mp_sizeinbase to return the value correctly with
1579 MPI. Affected file lib/silcmath/mp_mpi.c.
1581 * Fixed the stop_server signal to correctly stop the scheduler
1582 and gracefully stop the server when SIGTERM or SIGINT signals
1583 are received. Affected file silcd/silcd.c.
1585 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1587 * Simple handling of TERM and HUP signals. Also added some log
1588 flushing call around. Affected file is
1591 * Fixed small bugs in silclog.c. Now buffering output will take
1592 effect after 10 seconds since startup: This will ensure that
1593 no important startup messages are lost. Also output redirection
1594 will preserve original format ([Date] [Type] message).
1595 Affected file is lib/silcutil/silclog.c.
1597 * Added two options to the config file, in the logging section:
1598 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1599 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1601 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1603 * Do not print the warning about log files not being initialized
1604 more than once to avoid excess logging. Affected file is
1605 lib/silcutil/silclog.c.
1607 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1608 the SIM copying in make install in Makefile.am.pre.
1610 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1612 * Rewritten silclog APIs. Globally interesting changes follows:
1613 silc_log_set_files() changed to silc_log_set_file().
1614 silc_log_set_callbacks() changed to silc_log_set_callback().
1615 ROBOdoc documented silclog header file.
1616 SilcLogCb now returns bool to wether inihibit the default
1617 handler or not (to keep the old behaviour return always TRUE).
1618 The new APIs should also fix the problem of the
1619 silcd_error.log file that was written in the current directory.
1622 Log files streams will remain opened after silc_log_set_file()
1623 call, means less CPU usage notably on high traffic servers.
1624 File streams are now full buffered, and flushed to the disk
1625 every 5 minutes, lesses HD activity and CPU usage.
1626 Messages can be redirected, allowing admins to configure
1627 one single logfile for all server messages.
1628 the silc_log_quick global variable to activate fast-logging.
1629 Affected files lib/silcutil/silclog.[ch]
1631 * Changed some code to conform new silclog APIs. Affected
1632 files are doc/example_silcd.conf.in, silcd/server.c
1633 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1636 * Fixed a memory leak that could occur in some situations.
1637 Affected file silcd/serverconfig.c.
1639 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1641 * Added the silc_client_del_client to remove the client from
1642 all channels as well. Affected file lib/silcclient/idlist.c.
1644 * Fixed the client library to correctly remove the client
1645 from all channels when the client entry is being destroyed.
1646 Affected file lib/silcclient/client_notify.c, command.c.
1648 * Added auto-nicking support to the client library. If the
1649 applicatio now sets client->nickname it will be sent to the
1650 server after connecting by the library. This way for example
1651 SILCNICK (or IRCNICK) environment variables will have effect
1652 and always change the nickname automatically to whatever
1653 it is wanted. Affected file lib/silcclient/client.[ch].
1655 * Renamed silc_server_command_bad_chars to the
1656 silc_server_name_bad_chars and moved it to the
1657 silcd/server_util.[ch]. Added also new function
1658 silc_server_name_modify_bad to return nickname that
1659 includes bad characters as new nickname without those
1660 bad characters. This check and modify is now used in
1661 silc_server_new_client when the username is initially set
1662 as nickname, so it must be checked to be valid nickname.
1663 Affected file silcd/packet_receive.c.
1665 * The nickname length is now taken from the packet for real
1666 and not trusted to strlen() since it clearly can return
1667 wrong length for nickname including bad characters. This
1668 also applies to channel names. Affected file silcd/command.c.
1670 * Removed the lib/silcsilm/modules directory. Modules are now
1671 compiled into the lib/silcsim. Fixed the copying of the
1672 modules to follow symbolic links in Makefile.am.pre.
1674 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1676 * Fixed silc_string_regexify list creation. Fixes bugs with
1677 BAN and INVITE commands in server. The affected file is
1678 lib/silcutil/unix/silcunixutil.c.
1680 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * Removed the command destructor entirely from the server's
1683 command and command reply routines. It is not needed, and
1684 its usage was buggy and caused crashes. Affected files are
1685 silcd/command[_reply].[ch].
1687 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Cancel protocol and NULL sock->protocol if timeout
1690 occurred during protocol. Affected file silcd/server.c.
1692 * Cancel protocol timeouts always before calling the final
1693 callback, to assure that after final callback is called
1694 no other state will be called for the protocol anymore.
1695 Affected file silcd/protocol.c.
1697 * Print error log if incoming connection configuration could
1698 not be found. Affected file silcd/server.c.
1700 * Fixed JOIN command to correctly save the founder mode
1701 to the client on normal SILC server, when the channel
1702 was created by the router. Affected file silcd/command.c.
1704 * Fixed LIST command (hopefully) to send correct reply
1705 packets. Affected file silcd/command.c.
1707 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1709 * The silc_packet_receive_process now returns FALSE if the
1710 read data was invalid packet, and TRUE if it was ok.
1712 The server now checks that if unauthenticated connection
1713 sends data and its processing fails the server will close
1714 the connection since it could be a malicious flooder.
1716 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1718 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * Make sure the warning about error opening a log file is
1721 printed only once and not everytime it fails (produces
1722 too much useless log). Affected file lib/silcutil/silclog.c.
1724 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1726 * Made the silc_server_daemonise() function more readable.
1727 Affected file silcd/server.c.
1729 * Pid file is now optional, the user may comment it out from
1730 the config file. Removed define SILC_SERVER_PID_FILE, we
1731 don't need a default any longer. Affected file
1732 configure.in.pre, lib/Makefile.am.pre.
1734 * Make some use of the pid file. The server now dies at startup
1735 if it detects a valid pid file on his path. The server would
1736 die anyway in this circumstance, because of the bind() failure.
1737 Affected file silcd/silcd.c.
1739 * No longer compiling lib/dotconf.
1741 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1743 * Fixed JOIN command parsing not to crash. Affected file
1744 lib/silcclient/command.c.
1746 * Fied the NICK_CHANGE notify to add the new client entry
1747 even it is resolved. This removes an <[unknown]> nick
1748 thingy bug in the client. Affected file is
1749 lib/silcclient/client_notify.c.
1751 * Do not try to allocate 0 bytes (efence does not like it)
1752 in lib/silccore/silccomand.c when encoding payload.
1754 * Do not take IRCNICK as nickname in Irssi SILC client since
1755 it is not possible to set nickname before hand connecting
1756 the server (TODO has an entry about adding auto-nicking
1759 * Changed the silc_server_command_pending to check whether
1760 there already exists an pending entry with the specified
1761 command, command identifier and pending callback. This is
1762 to fix IDENTIFY and WHOIS related crashes that may register
1763 multiple pending commands with same identifier. Affected
1764 file silcd/command.c.
1766 * Fixed the server to reconnect to the router even if it
1767 was already reconnecting and EOF was received. This to
1768 fix a possibility that the server wouldn't ever try to
1769 auto-reconnect to the router. Affected file silcd/server.c.
1771 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1773 * Fixed the server's password authentication to use the
1774 length of the locally saved password, and not the one
1775 sent in the packet. Affected file silcd/protocol.c.
1777 * Fixed same password authentication problem in the
1778 Authentication Payload handling routines in
1779 lib/silccore/silcauth.c.
1781 * Yet another password authentication problem fixed with
1782 channel password handling in silcd/command.c.
1784 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1786 * If first character of string in silc_parse_userfqdn is '@'
1787 then do not parse it. Affected file is
1788 lib/silcutil/silcutil.c.
1790 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Fixed minor bug in IDENTIFY command reply sending, which
1793 caused various weird problems during JOIN when it was
1794 resolving names for users. Affected file silcd/command.c.
1796 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * Fixed the IDENTIFY command reply sending to chech better valid
1799 clients. It was possible to send incomplete list of replies.
1800 Affected file silcd/command.c.
1802 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1804 * Added silc_client_command[s]_[un]register functions now to
1805 dynamically register the commands in client library. Removed
1806 the static table of commands. This allows the client library
1807 to call commands without causing the application to know about
1808 what commands library has called.
1810 Removed the INFO command reply kludge to detect when the command
1811 was called by library. Now library use its own command reply
1812 function for INFO command.
1814 Added function silc_client_command_call to call a command.
1815 Application can use it to call command, not access the structure
1818 Now all commands that are sent by the client library (not
1819 explicitly sent by application) use own command reply functions.
1821 Affected files around lib/silcclient/ and in
1822 irssi/src/silc/core/.
1824 * Fixed the WHOIS command reply sending to chech better valid
1825 clients. It was possible to send incomplete list of replies.
1827 Fixed the WHOIS and IDENTIFY to send the request to router
1828 if normal server did not do it and did not find any results.
1830 Affected file silcd/command.c.
1832 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1834 * Moved the internal data from SilcClient context into its
1835 own file, not accesible to application. Affected files
1836 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1837 and other files in client library.
1839 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1841 * Added doc/examples installation target in Makefile.am.pre.
1844 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1847 commands the found client entry will be removed from the
1848 cache, after notifying application about the error. Affected
1849 file lib/silcclient/command_reply.c.
1851 * Changed the /MSG to check for exact nickname user gave, and
1852 not let `nick' match `nick@host' if it is only one found. Now,
1853 user must type the exact nickname (like nick@host2) even if
1854 there are no more than one same nicks found. This is to avoid
1855 a possibility of sending nickname to wrong nickname since
1856 `nick' could match `nick@host'. Affected file is
1857 irssi/src/core/silc-servers.c.
1859 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1861 * Do not print "you are now server operator" or similar when
1862 giving /away command. Affected files are
1863 irssi/src/silc/core/client_ops.c, silc-servers.h.
1865 * Made the silc_server_command_pending_error_check to send
1866 the same command reply payload it received back to the
1867 original sender of the command. This way all arguments
1868 that was received by the server will be received by the
1869 client too. Affected file silcd/command.c.
1871 * Added the silc_idcache_add to return the created cache entry
1872 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1874 * Add global clients to expire if they are not on any channel.
1875 This is because normal server will never know if they signoff
1876 if they are not on any channel. The cache expiry will take
1877 case of these entries. This is done by normal servers only.
1878 The affected files are silcd/command_reply.c,
1879 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1881 * If server receives invalid ID notification for WHOIS or
1882 IDENTIFY and the ID exists in the lists, it is removed.
1883 Affected file silcd/command_reply.c.
1885 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1886 in client then client entry that it matches is searched and
1887 the nickname is printed on the screen for user. Affected
1888 file irssi/src/silc/core/client_ops.c.
1890 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Use cache entry expire time in the LIST command reply to
1893 purge old entries from the cache after the LIST command
1894 reply has been received. This way we don't have non-existent
1895 entries in the cache for too long. Affected file is
1896 silcd/command_reply.c.
1898 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * If we are normal server, and we've not resolved client info
1901 in WHOIS or IDENTIFY from router, and it is global client,
1902 we'll check whether it is on some channel. If it is not
1903 then we cannot be sure about its validity and will resolve it
1904 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1905 file silcd/command.c.
1907 * Search channel by name (if possible) rather than by ID
1908 in IDENTIFY command's command reply. Affected file is
1909 silcd/command_reply.c.
1911 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1914 Updated specs and implemented it. Affected file silcd/command.c,
1915 silcd/packet_send.c and silcd/packet_receive.c.
1917 * Implemented the <founder auth> payload handling in the JOIN
1918 command. If provided all conditions for channel joining
1919 except requirement to provide correct passphrase can be
1920 overrided by the channel founder. Updated the protocol specs.
1921 Affected file silcd/command.c.
1923 Added support for founder auth in JOIN command in client
1924 library. Fixed the parsing of the JOIN command now to support
1925 all options as they should be. The affected file is
1926 lib/silcclient/command.c.
1928 * Optimized the WHOIS and IDENTIFY commands to send the request
1929 to router only if it includes nicknames or other names. If
1930 they include only IDs then check the local cache first before
1931 routing. Affected file is silcd/command.c.
1933 * Added channels topic announcements. Affected file is
1934 silcd/packet_receive.c and silcd/server.c.
1936 * Fixed the silc_server_send_notify_topic_set to really destine
1937 the packet to channel. Affected file silcd/packet_send.c.
1939 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1940 library. Affected file lib/silcclient/client_notify.c.
1942 * Added UMODE announcements. Affected file silcd/server.c.
1944 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Memory leak fixes in:
1948 lib/silcutil/silcsockconn.c
1949 lib/silcske/silcske.c
1950 lib/silcske/groups.c
1952 lib/silccrypt/silcpkcs.c
1953 lib/silccore/silccommand.c
1954 lib/silccore/silcidcache.c
1959 * ROBOdoc documented the lib/silcske/groups.h file and a
1960 bit changed the interface for better.
1962 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1964 * Update the client entry context in the ID cache after
1965 nick change. Affected file lib/silcclient/command.c.
1966 Fixes the CUMODE command when regaining founder privileges,
1967 and a little WHOIS problem.
1969 * Fixed silc_net_gethostbyname to correctly call the
1970 inet_ntop. Affected file lib/silcutil/silcnet.c.
1972 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1974 * Added IPv6 support checking to the configure.in.pre, added
1975 also --enable-ipv6 option to override the check. Affected
1976 file configure.in.pre.
1978 * The silc_thread_create now calls the start function
1979 directly if threads support is not compiled in. Removes
1980 ugly #ifdef's from generic code. Affected files are
1981 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1983 * Added silc_net_gethostby[name/addr]_async to asynchronously
1984 resolve. Affected files are lib/silcutil/silcnet.[ch].
1986 * Added support for rendering IPv6 based server, client and
1987 channel IDs. Affected file lib/silcutil/silcutil.c.
1989 * Added support for creating IPv6 based server IDs. Affected
1990 file is silcd/serverid.c.
1992 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1994 * Added silc_net_gethostby[addr/name] into the
1995 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1996 routines. Added silc_net_is_ip[4/6]. Affected file is
1997 lib/silcutil/unix/silcunixnet.c. All routines that take
1998 address as argument now supports both IPv4 and IPv6 addresses.
2000 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2002 * Fixed LIST command reply sending in server. Affected file
2005 * Server now sends the kicker's client ID in the KICK notify
2006 to the kicked client. Affected file silcd/command.c.
2008 * The client library now parses the kickers client ID and
2009 UI displays it. Affected files lib/silcclient/client_notify.c
2010 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2012 * Made all payload parsing function prototypes consistent.
2013 They all take now const unsigned char * and uint32 pair as
2014 the payload data instead of SilcBuffer. Changes all around
2015 the source tree. Other unsigned char* -> const unsigned char*
2016 changes around the tree as well.
2018 * Optimized SFTP client and server packet sending not to
2019 allocate new buffer for each packet but to recycle the
2020 first allocated buffer. Affected files are
2021 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2023 * Optimized the SFTP client to use SilcList instead of
2024 SilcDList for requests, because it is faster. Affected file
2025 is lib/silcsftp/sftp_client.c.
2027 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2028 into lib/silccore/silcid.[ch].
2030 Renamed silcpayload.[ch] into silcargument.[ch].
2032 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * If client entry is deleted with active key agreement
2035 session, abort the session.
2037 The silc_client_abort_key_agreement now calls the completion
2038 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2040 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2043 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Don't use __restrict in older GCC's. Affected file is
2046 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2048 * silc_net_localhost now attempts to reverse lookup the
2049 IP/hostname. Affected file lib/silcutil/silcnet.c.
2051 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2052 command. It can be used to gain founder privileges at
2053 the same time when joining the channel.
2055 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2056 kicker's client ID as well. Updated protocol specs.
2058 Defined that the server must send SILC_COMMAND_IDENTIFY
2059 command reply with error status to client who sent
2060 private message with invalid client ID.
2062 Updated the protocol specification.
2064 * Added silc_server_send_command_reply to send any
2065 command reply. Affected file silcd/packet_send.[ch].
2067 * Added silc_id_payload_encode_data to encode ID payload
2068 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2070 * The server now send IDENTIFY command reply with error
2071 status if client ID in private message is invalid. Affected
2072 file silcd/packet_receive.c.
2074 * Save the server key file with server's IP address in
2075 the filename instead of hostname. The affected file is
2076 irssi/src/silc/core/client_ops.c.
2078 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2080 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2083 * Added libtool support for compiling shared objects in
2084 lib/silcsim. Affected file configure.in.pre and
2085 lib/silcsim/Makefile.am. Original patch by cras.
2087 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2089 * Pid file configuration, and server's config file fixes
2090 patch by toma. Updated CREDITS file.
2092 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2094 * Fixed silc_client_channel_message to not try to decrypt
2095 the message twice if it resolved the destination client
2096 information. This could cause of dropping one channel
2097 message. Affected file lib/silcclient/client_channel.c.
2099 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2101 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2102 lib/silcclient/client.c. This function is used when the SILC
2103 Client is run under some other scheduler, or event loop or
2104 main loop. On GUI applications, for example this may be
2105 desired to used to run the client under the GUI application's
2106 main loop. Typically the GUI application would register an
2107 idle task that calls this function multiple times in a second
2108 to quickly process the SILC specific data.
2110 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2112 * Fixed silc_server_drop() for dropping the supplementary
2113 groups as well, this could cause a security hole on some
2116 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2118 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2121 * Write PID file after dropping privileges. Added -F option
2122 to run server on foreground. A patch by debolaz.
2123 Affected files silcd/server.c, silcd/silcd.c.
2125 * Fixed MOTD to return the MOTD file server name. Affected
2126 file silcd/command.c.
2128 * Added INFO command reply handling to the Irssi SILC Client.
2129 Affected file irssi/src/silc/core/client_ops.c.
2131 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2133 * Fixed the silc_idcache_list_* routines to really support
2134 the dynamic list. Fixes a crash. Affected file is
2135 lib/silccore/silcidcache.c.
2137 * Fixed the LIST command reply to really call LIST command's
2138 pending callbacks. Affected file silcd/command_reply.c.
2140 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2142 * Update conn->local_entry->nickname after giving NICK
2143 command. Affected file lib/silcclient/command.c.
2145 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2147 * Added the [pid] option to the silcd configuration file
2149 Affected files: serverconfig.[ch] and silcd.c
2151 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2153 * Save fingerprint in WHOIS command reply in server.
2154 Affected file silcd/command_reply.c.
2156 * Fixed NICK commands pending callback registration.
2157 Affected file lib/silcclient/command.c.
2159 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Use ++server->cmd_ident when sending commands in server,
2162 instead of random number. Affected file silcd/command.c.
2164 * Fixed GETKEY command reply to call actually GETKEY pending
2165 command callbacks. Affected file silcd/command_reply.c.
2167 * A bit stricter check for nicknames. Check for same nickname
2168 in NICK command also. Affected file silcd/command.c.
2170 * Do not call INFO command everytime client ID changes, only
2171 during first connecting. Affected file lib/silcclient/client.c.
2173 * Set the new nickname only after successful command reply for
2174 NICK command is returned by server. Affected file
2175 lib/silcclient/command.c.
2177 * Remove nicknames from nicklist during server_signoff notify.
2178 Should fix /NAMES bit more. The affected file is
2179 irssi/src/silc/core/silc-channels.c.
2181 * Added `fingerprint' field to the SilcIDListData in the
2182 silcd/idlist.h to hold the fingerprint of the client's
2185 Send the fingerprint of the client's public key in WHOIS
2188 Affected files silcd/command.c, and silcd/idlist.[ch].
2190 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2191 create fingerprint from given data.
2193 * Show the fingerprint of the client's public key in WHOIS.
2194 Affected files irssi/src/module-formats.[ch] and
2195 irssi/src/silc/core/client_ops.c.
2197 * Format the multiple same nicknames also during JOIN and
2198 NICK_CHANGE notifys. Affected file is
2199 lib/silcclient/client_notify.c.
2201 * Do not print error on screen for invalid private message
2202 payload since it can come if someone is sending private
2203 messages with wrong key. Affected file
2204 lib/silccore/silcprivate.c.
2206 * Fixed multiple concurrent /PING crash. Affected file
2207 lib/silcclient/command.c.
2209 * Changed the wrong ID encoding. All IP addresses must be
2210 in MSB first order in encoded format. They were encoded
2211 wrong and was in LSB format. Affected files are
2212 silcd/serverid.c, lib/silcutil/silcutil.c.
2214 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2216 * Call the `connect' client operation through the scheduler
2217 in case of error. Affected file lib/silcclient/client.c.
2219 * Call the `failure' client operation even if the error
2220 occurred locally during a protocol. Affected file is
2221 lib/silcclient/protocol.c.
2223 * Added support of sending LIST command to router from normal
2224 server. This way normal server can get list of all channels
2225 in the network too. Fixed the channel list sending in the
2226 server too. Affected files are silcd/command.c, and
2227 silcd/command_reply.[ch].
2229 * Added silc_server_update_channels_by_server and
2230 silc_server_remove_channels_by_server. They are used during
2231 disconnection of primary router and in backup router protocol.
2232 Affected file silcd/server_util.[ch], silcd/server.c and
2233 silcd/server_backup.c.
2235 * Fixed channel adding to global list in IDENTIFY command
2236 reply in server. Affected file silcd/command_reply.c.
2238 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * If the incoming packet type is REKEY or REKEY_DONE process
2241 that packet always synchronously. Fixes yet another MAC
2242 failed error on slow (dialup) connections. Affected file
2243 lib/silcclient/client.c and silcd/server.c.
2245 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * Call check_version SKE callback for initiator too. Affected
2248 file lib/silcske/silcske.c.
2250 * Implemented fix for security hole found in the SKE that was
2251 fixed in the specification few days back; the initiator's
2252 public key is now added to the HASH value computation.
2253 Added backwards support for the old way of doing it too, for
2254 old clients and old servers. Affected file is
2255 lib/silcske/silcske.c.
2257 * Enabled mutual authentication by default in SKE. If initiator
2258 is not providing mutual authentication the responder will
2259 force it. This will provide the proof of posession of the
2260 private key for responder. The affected files are
2261 lib/silcclient/protocol.c and silcd/protocol.c.
2263 * Do not cache anymore the server's public key during SKE.
2264 We do mutual authentication so the proof of posession of
2265 private key is done, and if the server is authenticated in
2266 conn auth protocol with public key we must have the public
2267 key already. Affected file silcd/protocol.c.
2269 * Added new global debug variable: silc_debug_hexdump. If
2270 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2271 file lib/silcutil/silclog.[ch].
2273 * Fixed compilation warning due to char * -> const char *.
2274 Affected files lib/silcutil/silcnet.h, and
2275 lib/silccore/silcauth.[ch].
2277 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2279 * Fixed CMODE command when new channel key was created. If
2280 the creation failed the old key was removed. Next time giving
2281 same command would crash the server since the old key was
2282 freed already. Affected file silcd/command.c.
2284 * Fixed the silc_server_announce_get_channels to not crash
2285 on reconnect. Affected file silcd/server.c.
2287 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2289 * Added silc_log_set_debug_string function to set a regex
2290 string to match for debug output. Only the function names,
2291 or filenames matching the given debug string is actually
2292 printed. This way it is possible to filter out those debug
2293 strings that user is not interested in.
2295 Fixed a bug in silc_string_regexify.
2297 Affected files lib/silcutil/silclog.[ch], and
2298 lib/silcutil/unix/silcunixutil.c.
2300 * Changed the -d options in both server and Irssi SILC client
2301 to take the debug string as argument. Affected files
2302 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2304 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Added silc_hash_babbleprint to create a Bubble Babble
2307 Encoded fingerprint. The encoding is developed by Antti
2308 Huima (draft-huima-babble-01.txt), and it creates human
2309 readable strings out of binary data. Affected file
2310 lib/silccrypt/silchash.[ch].
2312 * Print the babble print now in addition of fingerprint as well
2313 in Irssi SILC client. Affected files are
2314 irssi/src/fe-common/silc/module-formats.[ch],
2315 irssi/src/fe-common/silc/core/client_ops.c.
2317 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2319 * Fixed a security problem found in SKE. The initiator's
2320 public key too is now added to the HASH hash value creation
2321 which is signed by the responder to create the SIGN value.
2322 This will prevent anyone in the middle to lie to the responder
2323 about the initiator's public key. If this is done now, the
2324 man in the middle will get caught. Updated the protocol
2327 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2329 * Better installation directory handling. Configure module
2330 paths and other paths automatically to example_silc* files
2331 in doc/. A patch by toma.
2333 * Fixed compiler warning from MPI library, and from SILC RNG.
2336 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2337 It can be configured with ./configure. A patch by toma.
2339 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2341 * Find correct make to use in prepare-clean. A patch by
2342 toma. Affected file prepare-clean.
2344 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2346 * Added irssi variables use_auto_addr, auto_bind_ip,
2347 auto_bind_port and auto_public_ip.
2349 * Changed the interface for silc_client_send_key_agreement
2350 in lib/silcclient/silcapi.h
2354 irssi/src/silc/core/silc-core.c
2356 lib/silcclient/silcapi.h
2357 irssi/src/silc/core/silc-channels.c
2358 lib/silcclient/client_keyagr.c
2361 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2363 * Added silc_pkcs_public_key_compare to compare two
2364 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2366 * Check that the client who set the founder mode on the
2367 channel is the same client that is giving the founder
2368 mode to itself. It is done by comparing the saved public
2369 key (it is saved even in the authentication is passphrase).
2370 Affected file silcd/command.c.
2372 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2374 * Do not process packet for disconnected socket connection.
2375 Affected file lib/silccore/silcpacket.c.
2377 * Process the DISCONNECT packet through scheduler in the
2378 client library. Affected file lib/silcclient/client.c.
2380 * Fixed the silc_client_packet_parse to not to increase
2381 the packet sequence number if the conn->sock and the
2382 current socket connection is not same. This can happen
2383 for example during key agreement when the conn includes
2384 multiple socket connections (listeners). Affected file
2385 lib/silcclient/client.c.
2387 * The sender of the file transfer request now provides also
2388 the pointer (listener) for the key exchange protocol. If
2389 the listener cannot be created then it sends empty key
2390 agreement and lets the receiver provide the listener.
2392 Added `local_ip' and `local_port' arguments to the
2393 silc_client_file_send. If they are provided they are used,
2394 if not then it will attempt to find local IP address, if
2395 not found or bind fails then the remote client will provide
2398 Affected files are lib/silcclient/client_ftp.c and
2399 lib/silcclient/silcapi.h.
2401 * Extended the FILE SEND command to support defining the
2402 local IP and port for key exchange listener. They are
2403 optional. Affected file irssi/src/silc/core/silc-servers.c.
2405 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2407 * Defined to WHOIS command reply the sending of fingerprint
2408 of the client's public key (if the proof of posession of the
2409 corresponding private key is verified by the server).
2410 Updated to the protocol specification.
2412 * Added support of receiving the client's public key's
2413 fingerprint in command reply in client library. Affected
2414 file is lib/silcclient/command_reply.c, and
2415 lib/silcclient/idlist.[ch].
2417 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Do not send over 128 chars long nickname to the server
2420 in NICK command. Affected file lib/silcclient/command.c.
2422 * Do not send over 256 chars long channel names to the server
2423 in JOIN command. Affected file lib/silcclient/command.c.
2425 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2427 * Assure that silc_server_close_connection cannot be called
2428 twice for same socket context. Affected file is
2431 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2433 * Send error message to application if opening file for
2434 writing during file transfer fails. Affected file is
2435 lib/silcclient/client_ftp.c.
2437 Remove all file transfer sessions for a client that we're
2438 removing from ID cache.
2440 Affected file is lib/silcclient/client_ftp.c.
2442 * Fixed silc_net_addr2bin to return correct address. Affected
2443 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2445 * Fixed file transfer session removing on signoff notify.
2446 Affected file irssi/src/silc/core/silc-servers.c.
2448 * Added the SilcClientFileError to be returned in the monitor
2449 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2450 Affected file lib/silcclient/silcapi.h.
2452 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2454 * Fixed a crash in silc_client_ftp_free_sessions and
2455 silc_client_ftp_session_free_client. Affected file
2456 lib/silcclient/client_ftp.c.
2458 * Added `disabled' field in the SilcChannelEntry in the server
2459 to indicate if the server entry is disabled. Affected file
2460 silcd/idlist.h, silcd/command[_reply].c.
2462 * SILC server adds now /var/run/silcd.pid everytime it is
2463 started. Affected file silcd/silcd.c.
2465 * Added silc_server_packet_send_clients to send a packet to
2466 the provided table of client entries. Affected file
2467 silcd/packet_send.[ch].
2469 * Fixed a crash in client resolving in client_prvmsg.c in
2470 client library. Affected file lib/silcclient/client_prvmsg.c.
2472 * Do not actually remove the client directly from ID cache
2473 during SERVER_SIGNOFF, but invalidate it. This way we
2474 preserve the WHOWAS info for the client. Affected file
2475 silcd/server_util.c.
2477 * Fixed SERVER_SIGNOFF notify handling in the server. The
2478 server is now able to process incoming SERVER_SIGNOFF notify
2479 for a server that it doesn't even know about. It will remove
2480 the clients provided in the notify. Affected file
2481 silcd/packet_receive.c.
2483 * Check for partial packet in data queue after every packet that
2484 was found from the queue. Return and wait for more data if
2485 there is partial data in queue. Affected file is
2486 lib/silccore/silcpacket.c.
2488 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Added SilcClietFileError enum to indicate error in
2491 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2492 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2493 Affected files lib/silcclient/silcapi.h and
2494 lib/silcclient/client_ftp.c.
2496 * Check that newsize in silc_buffer_realloc is larger than
2497 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2499 * Added better monitor of file transfers. It now monitors
2500 key agreement protocol during the file transfer too. Added
2501 error reporting too. Affected files
2502 irssi/src/silc/core/silc-servers.c,
2503 irssi/src/fe-common/silc/module-formats.[ch].
2505 * Wrote a help file for FILE command.
2507 * Added silc_rng_global_get_byte_fast to get not-so-secure
2508 random data as fast as possible. Random data is read from
2509 /dev/urandom if available and from the SILC RNG if not
2510 available. It is used in padding generation. Affected file
2511 lib/silccrypt/silcrng.[ch].
2513 * All packets in client library are now processed synchronously.
2514 Optimized packet processing a lot. Affected file
2515 lib/silcclient/client.c.
2517 * All server connection packets are processing synchronously
2518 now in server, to optimize packet processing. Affected file
2521 * Include files are installed now only in Toolkit distribution
2522 if make install is given. Affected files: all Makefile.am's.
2524 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2526 * Assure that silc_client_notify_by_server_resolve does not
2527 resolve the client information multiple times. If it cannot
2528 be found by the first it cannot be found at all. Affected
2529 file lib/silcclient/client_notify.c.
2531 * Fixed WHOWAS command reply calling. Affected file
2532 lib/silcclient/command_reply.c.
2534 * Removed all references to silc_idlist_get_client from the
2535 Irssi SILC client since that call is internal call used by
2536 the library. The Irssi SILC client will use now client
2537 retrieval functions found in silcapi.h.
2539 * Fixed a bug in resolving nickname info before sending
2540 private message. It used freed memory. Affected file
2541 irssi/src/silc/core/silc-servers.c.
2543 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Assure my_channels statistics cannot go negative in server.
2546 Affected files silcd/server.c, silcd/server_util.c.
2548 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2552 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2554 * Win32 Toolkit changes. Affected files
2555 win32/silc.dsw, win32/libsilc/libsilc.def,
2556 win32/libsilcclient/libsilc.def,

2558 lib/sftp/sftp_fs_memory.c.
2560 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * Added silc_net_localip to return local host's IP address.
2563 Affected file lib/silcutil/silcnet.[ch].
2565 * If key exchange or rekey protocol is active for a connection
2566 parse all packets syncronously since there might be packets
2567 in packet queue that we are not able to process without first
2568 processing packets before them. Affected file silcd/server,
2569 lib/silcclient/client.c.
2571 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2572 whether library should continue processing the packet.
2573 Affected file lib/silccore/silcpacket.h.
2575 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2576 SilcSFTPMonitorData to SFTP server to monitor various
2577 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2578 lib/silcsftp/sftp_server.c.
2580 * Added silc_file_size to return file size. Affected file
2581 lib/silcutil/silcutil.[ch].
2583 * Implemented the file transfer support for the client library.
2584 Added preliminary support for simple client to client one-file
2585 transmission. Affected file lib/silcclient/client_ftp.c,
2586 lib/silccilent/client.[ch].
2588 * Added new local command FILE to the Irssi SILC Client.
2589 It is used to perform the file transfer. It has subcommands
2590 SEND, RECEIVE, SHOW and CLOSE. Affected files
2591 irssi/src/silc/core/client_ops.c,
2592 irssi/src/silc/core/silc-server.[ch].
2594 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2596 * Relay the SILC_PACKET_FTP in the server. Affected files
2597 silcd/server.c and silcd/packet_receive.c.
2599 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Renamed silc_file_read and silc_file_write to functions
2602 silc_file_readfile and silc_file_writefile. Added function
2603 silc_file_open and silc_file_close. Affected files
2604 lib/silcutil/silcutil.[ch].
2606 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * Resolve the client info when received private message or
2609 channel message for a client which nickname we don't know.
2610 Affected files lib/silcclient/client_prvmsg.c and
2611 lib/silcclient/client_channel.c.
2613 * Do not crash in /KEY if client is not connected. Affected
2614 file irssi/src/silc/core/silc-channels.c.
2616 * Added SilcClientStatus field to the SilcClientEntry in the
2617 lib/silcclient/idlist.h.
2619 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2620 is incomplete and is being resolved, it won't be resolved
2623 Make sure also that USERS command reply does not resolve
2624 twice information. Affected file is
2625 lib/silcclient/command_reply.c.
2627 Make sure that silc_client_get_clients_by_list does not
2628 resolve twice same information.
2630 * Check for valid client->id in the silc_server_free_client_data.
2631 Affected file silcd/server.c.
2633 * Fixed /GETKEY nick@server not to crash if the server entry
2634 is not found. Affected file lib/silcclient/command.c.
2636 * Fixed the silc_server_check_cmode_rights to check the
2637 requested modes correctly. Affected file silcd/command.c.
2639 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * Better checks for non-printable chars in nick added.
2642 Affected file silcd/command.c.
2644 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2646 * Call the silc_server_udpate_servers_by_server in the
2647 primary router that comes back online in the backup resuming
2648 protocol. Otherwise it routes packets wrong. Affected file
2649 silcd/server_util.[ch], silcd/server_backup.c.
2651 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2654 lib/silcutil/silcbuffmt.[ch].
2656 * Redefined the SILC packet header to include the padding
2657 length. Affected file lib/silccore/silcpacket.[ch].
2659 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2660 length for maximum padding up to 128 bytes). Affected
2661 file lib/silccore/silcpacket.h.
2663 * Removed all backwards support for old 0.5.x MAC thingies.
2664 The SILC packet header change makes it impossible to be
2665 backwards compatible.
2667 * Send the ENDING packet with timeout in the backup resuming
2668 protocol. This is to assure that all routers has connected
2669 to the primary router. Affected file silcd/server_backup.c.
2671 * Changed the RNG to take the first IV from random data. It
2672 used to take it from zero actually. Changed the RNG also
2673 to use /dev/urandom during session. /dev/random is used
2674 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2676 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Changed the SILC packet header to have the first two bytes
2679 (the packet length) encrypted. Affected files aroung the
2680 code tree, lib/silccore/silcpacket.[ch]. Removed the
2681 SilcPacketCheckDecrypt callback. It is not needed anymore
2682 since the silc_packet_receive_process will determine now
2683 whether the packet is normal or special.
2685 * Implemented the unidirectional MAC keys. Affected files
2686 lib/silcske/silcske.c, silcd/protocol.c and
2687 lib/silcclient/protocol.c.
2689 * Implemented the packet sequence number to the MAC computation.
2690 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2691 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2692 lib/silcclient/protocol.c.
2694 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Allow backup router to announce servers. All servers
2697 announced by backup router are added to the global list
2698 automatically. Update hte server's socket to our primary
2699 router also when backup router announces a server.
2700 Affected file silcd/packet_receive.c.
2702 * Do not update the client->router in the function
2703 silc_server_udpate_clients_by_server if the client is on
2704 global list. We might fail to find any specific server
2705 for locally connected clients and local cell clients. They
2706 should still use the `from' and not `to' as client->router.
2707 This fixes backup router resuming protocol. Affected file
2708 silcd/server_util.c.
2710 * Decrease channel statistics count only if the channel
2711 deletion worked. Affected files are silcd/server.c and
2712 silcd/server_util.c.
2714 * Added silc_server_update_servers_by_server to update origin
2715 of all server entries. Used during backup router protocol.
2716 Affected files silcd/server_util.[ch], silcd/server.c. and
2717 silcd/backup_router.c.
2719 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2720 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2721 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2722 lib/silccrypt/silchmac.c.
2724 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2726 * Assure that router cannot reroute the same channel message
2727 to the sender. Affected file silcd/packet_receive.c.
2729 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2731 * Made better checks that the channel message is not sent
2732 to the router it came from. Affected file is
2733 silcd/packet_send.c. Fixed memory leak too.
2735 * Announce informations for incoming router connection, but
2736 only after checking if it is replaced by backup router.
2737 Affected file silcd/packet_receive.c.
2739 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Fixed the backup resuming protocol to work in multiple
2742 router environment. Affected file silcd/server_backup.c.
2744 * Route packet only to one router in the function
2745 silc_server_packet_send_to_channel. Affected file is
2746 silcd/packet_send.c.
2748 * Fixed silc_server_send_notify_dest to set the broadcast
2749 flag. Fixed the silc_server_send_notify_topic to actually
2750 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2751 Affected file silcd/packet_send.c.
2753 * Changed the SFTP Filesystem interface. Changed the
2754 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2755 the filesystem operation function. The SilcSFTPFilesystem
2756 is now a context that is allocated by all filesystem allocation
2757 functions and it already includes the operations structure
2758 and filesystem specific context. It is given as argument
2759 now to the silc_sftp_server_start. This made the interface
2760 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2761 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2763 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * Changed the backup router adding and getting interfaces
2766 in the server. The router that will be replaced by the
2767 specified backup router is now sent as argument. Affected
2768 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2771 * Added silc_net_addr2bin_ne to return the binary form of
2772 the IP address in network byte order. Affected files
2773 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2775 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2777 * Check for existing server ID in silc_server_new_server
2778 and in silc_server_connect_to_router_final and remove the
2779 old entry if it exists. Affected file silcd/packet_receive.c,
2782 * Send the channel message always to only one router, either
2783 in upstream or downstream. Affected file is
2784 silcd/packet_send.c.
2786 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * Wrote the definition of the backup resuming protocol to the
2789 protocol specification.
2791 * Removed one redundant channel key generation from normal
2792 server during joining procedure. Removed one redundant
2793 channel key sending from server to router during joining
2794 procedure. Affected file silcd/command.c.
2796 * Made minor bugfixes to the backup router resuming protocol.
2797 Affected file silcd/server_backup.c, server.c.
2799 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2801 * Added --disable-asm configuration option. Affected files
2802 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2805 * Implemented the backup resuming protocol that is used to
2806 resume the primary router position in the cell after the
2807 primary router comes back online. Affected files
2808 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2809 and silcd/server_util.[ch].
2811 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2813 * Sleep two (2) seconds after sending QUIT command to server.
2814 Affected file lib/silcclient/command.c.
2816 * Assure that if outgoing data buffer is pending do not force
2817 send any data. Affected file silcd/packet_send.c.
2819 * Assure that if outgoing data buffer is pending do not force
2820 send any data. Affected file lib/silcclient/client.c.
2822 * Implemented the backup router support when the primary router
2823 goes down. The servers and routers can now use the backup
2824 router as new primary router without loosing connectivity.
2826 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2828 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2829 in the server to indicate disabled entry. All data read
2830 from the connection will be ignored and no data is sent
2831 for entry that is disabled. Affected files are
2832 silcd/idlist.h, silcd/server.c.
2834 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2836 * Created SFTP client and server test programs in the
2837 lib/silcsftp/tests directory.
2839 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2841 * Implemented memory filesystem (virtual filesystem) for
2842 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2845 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Implemented the SFTP (SSH File Transfer Protocol) to the
2848 lib/silcsftp. It includes SFTP client and SFTP server
2851 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * Moved lib/silccore/silcprotocol.[ch] to the
2854 lib/silcutil library.
2856 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2857 take variable argument list pointer as argument. Affected
2858 file lib/silcutil/silcbuffmt.[ch].
2860 * Added silc_buffer_set function that is used to set data
2861 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2862 Affected file lib/silcutil/silcbuffer.h.
2864 * Changed various routines in the core library to use the new
2865 silc_buffer_set instead of allocating new buffer only for
2868 * Added 64-bit value formatting and unformatting support to the
2869 silc_buffer_[un]format routines. Affected file is
2870 lib/silcutil/silcbuffmt.[ch].
2872 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2873 to includes/bitmove.h.
2875 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2877 * Fixed channel user mode saving in client library. Affected
2878 file lib/silcclient/command[_reply].c.
2880 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Defined the file transfer to the SILC Protocol. Added
2883 new packet type SILC_PACKET_FTP and defined File Transfer
2884 Payload. The mandatory file transfer protocol is SFTP
2885 (SSH File Transfer Protocol). Affected file in addition
2886 of the internet draft is lib/silccore/silcpacket.h.
2888 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2889 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2890 is used as part of backup router protocol when the primary
2891 router of the cell is back online and wishes to resume
2892 the position as primary router.
2894 * Redefined the MAC generation keys in the protocol. The
2895 same key is not used anymore in both direction. Both
2896 direction will now use different keys for sending and
2897 receiving. This fixes a potential security flaw. This
2898 change causes incompatibilities in the protocol.
2900 * Redefined also the MAC computation from the packet.
2901 An packet sequence number is now added to the MAC
2902 computation. This prevents possible replay attacks against
2903 the protocol. This change too causes incompatibilities
2906 Added `sequence' field to the SilcPacketContext to hold
2907 the current sequence number for the packet.
2909 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Added `created' field to the SilcIDListData in the file
2912 silcd/idlist.h to indicate the time when the entry was
2915 * Added `created' field to the SilcChannelEntry too. Affected
2916 file silcd/idlist.h.
2918 * Added `creation_time' aguments to all the announcement functions
2919 in the server. If it is provided then only the entries that
2920 was created after the provided time frame are actually
2921 announced. Affected file silcd/server.[ch].
2923 * The protocol says that the Channel ID's IP address must be
2924 based on the router's IP address. Added check for this in
2925 the silc_server_new_channel when processing incoming New Channel
2926 Payload. Affected file silcd/packet_receive.c.
2928 * Print out the correct version with --version in SILC client.
2929 Affected file irssi/src/silc/core/silc-core.c.
2931 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Fixed WHOWAS command to check for completnes of the client
2934 entry always, not just when the command is coming from client.
2935 Affected file silcd/command.c.
2937 * Added new function silc_server_packet_queue_purge to purge the
2938 outgoing data queue to the network. After the function returns
2939 it is guaranteed that the outgoing packet queue is empty.
2940 Affected file silcd/packet_send.[ch].
2942 * Purge the outgoing packet queue in the rekey protocol's final
2943 callback to assure that all rekey packets go to the network
2944 before quitting the protocol. Affected file silcd/server.c.
2946 * Added silc_client_packet_queue_parse as similar function as
2947 in server to the client library. The affected file is
2948 lib/silcclient/client.c.
2950 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2952 * Splitted silcd/server.c and created silcd/server_util.[ch]
2953 for utility functions.
2955 * Added new socket flag SILC_SF_DISABLED to indicate that the
2956 connection is open but nothing can be sent to or received from
2957 the connection. Affected file lib/silcutil/silsockconn.[ch].
2958 The checking for disabled socket is checked in the low level
2959 silc_socket_write and silc_socket_read functions.
2961 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Allow only nicknames and channel names that fits into the
2964 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2966 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2968 * When processing JOIN command reply in server check that if
2969 the channel exists in our global list we'll move it the local
2970 list. Affected file silcd/command_reply.c.
2972 * Fixed the check whether client is joined on the channel already
2973 in JOIN command. Affected file lib/silcclient/command.c.
2975 * Fixed the JOIN command reply to check whether the channel
2976 already exists. Affected file lib/silcclient/command_reply.c.
2978 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * Added silc_ske_status_string to map the SKE error numbers
2981 to readable strings. The affected files are
2982 lib/silcske/silcske[_status].[ch].
2984 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2986 * Do not show the private channels on the WHOIS channel list
2987 as it is not allowed by the protocol. The affected file is
2990 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2992 * Assure that the packet length digged from the actual packet
2993 is something sensible in the silc_packet_decrypt_rest_special
2994 in lib/silccrypt/silcpacket.c.
2996 * Free and NULL the allocated pointer in silc_hmac_alloc if
2997 the HMAC allocation fails. The affected file is
2998 lib/silccrypt/silchmac.c.
3000 * Print the selected security properties to the log files in
3001 the server. Affected file silcd/protocol.c.
3003 * Add SKE's reference counter even if calling the completion
3004 callback manually. Otherwise it goes negative, although it
3005 does not cause any problems. The affected file is
3006 lib/silcske/silcske.c.
3008 * Remove the client entry with short timeout after giving the
3009 KILL command. Affected file lib/silcclient/command.c.
3011 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3012 case all found clients are already disconnected (WHOWAS would
3013 found them) in the server. Affected file silcd/command.c.
3015 * Update the last_receive (time of last data received) to be
3016 updated only when received private or channel message so that
3017 the idle time showed in WHOIS makes more sense.
3019 * Added boolean field `valid' in to the SilcClientEntry in the
3020 client library to indicate whether the entry is valid or not.
3021 This fixes the nickname change bug on channel when changing
3022 the nickname to be same than the old (like nick to Nick) the
3023 nickname formatter doesn't set the new nick anymore to Nick@host.
3024 Affected file lib/silcclient/idlist.[ch].
3026 * Now actually fixed the nickname changing on disconnection.
3027 Added new function silc_change_nick to the Irssi SILC Client.
3028 Affected file irssi/src/silc/core/client_ops.c,
3029 irssi/src/silc/core/silc-nicklist.[ch].
3031 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3033 * Check that the public key exists in the GETKEY command before
3034 trying to encode it. Affected file silcd/command.c.
3036 * Print some notifications on received public keys with GETKEY
3037 command in the Irssi SILC Client. Affected files are
3038 irssi/src/fe-common/silc/module-formats.[ch],
3039 irssi/src/silc/core/client_ops.c.
3041 * Use IDENTIFY command to resolve the server information in the
3042 GETKEY command instead of INFO command. Affected file
3043 lib/silcclient/command.c.
3045 * All command reply functions in the client library now calls
3046 the pending command reply callbacks even if an error has
3047 occurred. The server has done this a long time and now it was
3048 time to move the client library to this as well. Now all
3049 errors can be delivered back to the pending command reply
3050 callbacks if necessary. Affected files are
3051 lib/silcclient/command[_reply].[ch].
3053 * Change the nickname on disconnection back to the username
3054 because in reconnect the server will enforce it to it anyway.
3055 Affected file irssi/src/silc/core/silc-servers.c.
3057 * Fixed a config file parsing bug in the Irssi SILC client.
3058 Affected file irssi/src/silc/core/clientconfig.c.
3060 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3062 * When printing the channel mode on JOIN, verify that the
3063 channel key and channel's HMAC are valid. Affected file
3064 irssi/src/silc/core/client_ops.c.
3066 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3068 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3069 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3070 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3072 * Removed channel key rekey task deleting from the function
3073 silc_server_save_channel_key. Affected file silcd/server.c.
3074 Added explicit timeout task context instead that is used to
3075 delete the task if we are registering a new task before the
3076 new task has elapsed.
3078 * When channel key rekey occurs the client library now saves
3079 the old channel key for a short period of time (10 seconds) and
3080 is able to use it in case some is still sending channel
3081 messages encrypted with the old key after the rekey. Affected
3082 file lib/silcclient/[idlist.h|client_channel.c].
3084 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3086 * Added check to the silc_server_new_id_real to not accept
3087 new ID if it is the sender's own ID. Affected file is
3088 silcd/packet_receive.c.
3090 * Assure that we do not announce ourself or the one we've
3091 sending our announcements when we're router and are announcing
3092 servers to our primary router. Affected file silcd/server.c.
3094 * Fixed silc_server_command_identify_check_client to assemble
3095 correct WHOIS packet. It send corrupted WHOIS packet and
3096 caused problem with router to router connections. Affected
3097 file silcd/command.c.
3099 Fixed also silc_server_command_whois_check the same way
3100 as for the IDENTIFY command.
3102 * Added new SilcIDListStatus to the server in the SilcIDListData
3103 structure. The status now includes the current status of
3104 the entry (like registered, resolved etc.). Affected file
3105 silcd/idlist.[ch]. Defined a bunch of different status types
3106 as well. This replaced the old boolean registered field as well.
3108 Added resolve_cmd_ident field to the SilcClientEntry structure
3109 too so that if the entry is for example being resolved so
3110 another command may attach to the same pending command reply
3111 without requiring to resolve the same entry again. This concept
3112 should optimize the WHOIS and the IDENTIFY resolving under
3113 heavy load by taking away unnecessary resolving for entries
3114 that are being resolved already.
3116 Added support for adding multiple pending commands for one
3117 command idenfier. Affected file silcd/command[_reply].[ch].
3119 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3120 before deleting the data. Otherwise the hash table will have
3121 freed data in comparison functions. Affected file is
3122 silcd/command_reply.c.
3124 * Fixed silc_idlist_replace_client_id to add the new entry to
3125 the cache with NULL nickname. Otherwise there will be invalid
3126 memory as the nickname after the nickname is freed. Affected
3127 file silcd/packet_receive.c.
3129 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3130 saved into wrong slots because the previous number of entries
3131 was not taken into account. Affected file silcd/idlist.c.
3132 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3134 * If we are router and we receive JOIN notify to a channel that
3135 does not have any users then notified client is marked as the
3136 channel founder, as it is it. The affected file is
3137 silcd/packet_receive.c
3139 * Added to the extended hash table API's table_del_*ext functions
3140 the destructor as argument too, so that the caller can decide
3141 which destructor to use or whether to use destructor at all.
3142 Affected file lib/silcutil/silchashtable.[ch].
3144 * Fixed ID Cache purging. It actually deleted the entries from
3145 the hash table after the data was freed. The hash table ended
3146 up comparing freed memory. The affected file is
3147 lib/silccore/silcidcache.c.
3149 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3151 * Fixed Irssi SILC client's KILL command's HELP syntax.
3153 * The USERS command now resolves the detailed user information
3154 if the userinfo field is missing. Affected file is
3155 lib/silcclient/command_reply.c.
3157 * Do not print error in silc_file_read if the read file does
3158 not exist. Just silently return NULL. Affected file is
3159 lib/silcutil/silcutil.c.
3161 * Fixed the silc_log_output to not wine about NULL filename
3162 and to not create some bogus " " filename. Affected file is
3163 lib/silcutil/silclog.c.
3165 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3167 * Fixed various printing bugs on the user interface in the
3168 Irssi SILC Client. Minor changes that were forgotten from
3171 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3173 * Fixed the configure.in.pre and the compilation and distribution
3174 environment to support the new autoconf 2.52. That version is
3175 now required to compile the CVS trunk.
3177 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3180 to generally parse user@fqdn format strings. Affected file
3181 lib/silcutil/silcutil.c.
3183 * Added nickname_format and nickname_force_format fields to the
3184 SilcClientParams structure. The first one defines the format
3185 for the nicknames that the library will enforce if the receives
3186 multiple same nicknames. The second one is boolean value and
3187 can be used to force the library to always enforce the format
3188 to the nicknames regardles whether there are multiple nicknames
3189 or not. This configurable formatting was employed to flexibly
3190 support accessing multiple nicknames from the user interface.
3191 The userinterface can now set the nicknames to what ever format
3192 they prefer. Affected file lib/silcclient/silcapi.h.
3194 Added function silc_client_nickname_format to the file
3195 lib/silcclient/idlist.c. It performs the nickname formatting.
3197 Added new field `hostname´ to the SilcClientEntry context.
3198 It holds the hostname of the client. Affected file is
3199 lib/silcclient/idlist.h.
3201 * Irssi SILC Client sets the nicknames in nick@hostn format.
3202 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3203 irssi/src/silc/core/silc-core.c.
3205 The WHOIS printing now also shows both the real nickname and
3206 the formatted nickname so that user knows how to access the
3207 user if there are multiple same nicknames cached. Affected
3208 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3209 printing formatting too to take the hostname now as a separate
3210 argument. The Affected file is
3211 irssi/src/fe-common/silc/modules-formats.[ch].
3213 * Changed the silc_client_get_clients_local to accept the formatted
3214 nickname as argument. It accepts the real nickname too but the
3215 formatted nickname can be used to find the true entry from
3216 multiple entries. Affected file lib/silcclient/silcapi.h and
3217 lib/silcclient/idlist.c.
3219 * Added nickname_format_parse field to the SilcClientParams.
3220 It is a callback function provided by the application to parse
3221 the nickname out of the formatted nickname string. The library
3222 calls it to get the nickname from the formatted string. Since
3223 the application generally knows better the format of the nickname
3224 string it parses it instead of the library, even though library
3225 encodes the formatted string. If the callback function is not
3226 provided then the library will use the string as is. The
3227 affected file is lib/silcclient/silcapi.h.
3229 * All the nickname strings passed to the client library in
3230 commands are now expected to be formatted nickname strings.
3231 If the command does not support the formatted nickname string
3232 it will assume that the sent string is the actual nickname.
3233 Affected file lib/silcclient/command.c.
3235 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3237 * Added public key authentication support to OPER and SILCOPER
3238 commands in the client library. Affected file is
3239 lib/silcclient/command.c.
3241 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3243 * Changed the get_auth_methdod client operation to be asynchronous.
3244 It can be async if the application resolves the authentication
3245 method from the server during the negotiation. Added new
3246 SilcGetAuthMeth completion callback that the application will
3247 call after resolving the authentication method.
3249 Added function silc_client_request_authentication_method that
3250 the application can use to resolve the authentication method
3251 from the server. Added also SilcConnectionAuthRequest callback
3252 that the library will call after the server has replied. The
3253 application can call this function if it does not know the
3254 current authentication method.
3256 Affected files are lib/silcclient/client.c and
3257 lib/silcclient/silcapi.h.
3259 * The Irssi SILC client now automatically resolves the authentication
3260 method incase any configuration information is not present (and
3261 currently there never is). The affected file is
3262 irssi/src/silc/core/client_ops.c.
3264 * Fixed public key authentication from the client library.
3265 Affected file lib/silcclient/protocol.c. Changed also the
3266 protocol specification about the public key authentication in
3267 the connection authentication protocol. The actual data to be
3268 signed is now computed with a hash function before signing.
3270 * Fixed the public key authentication from the server as well.
3271 Affected file silcd/protocol.c.
3273 * Removed the mlock()'s from the memory allocation routines.
3274 Affected file lib/silcutil/silcmemory.c. The ./configure does
3275 not check anymore for the mlock(). Affected file is
3278 * Fixed USERS command in server to allow the execution of the
3279 command for private and secret channels if the client sending
3280 the command is on the channel. Affected file silcd/command.c.
3282 * Fixed silc_client_get_clients_local to return the clients
3283 count correctly. It could return wrong value. Affected file
3284 lib/silcclient/idlist.c.
3286 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3288 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3289 types. The assembler optimizations seemed not to like 64-bit
3290 data types. The assmebler optimizations thus are now enabled
3291 also for BSD systems as opposed to only enable them for Linux.
3293 * Do not check for threads at all on BSD systems. Affected
3294 file configure.in.pre.
3296 * Removed -n and -h options from the Irssi SILC Client since
3297 they are not used in silc.
3299 * Fixed the prime generation to assure that the first digit
3300 of the generated random number is not zero since our conversion
3301 routines does not like number strings that starts with zero
3302 digit. If zero digit is seen the random number is regenerated.
3303 This caused some corrupted RSA keys when the zero first digit
3304 was met. Affected file lib/silcmath/silcprimegen.c.
3306 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3308 * Fixed WIN32 configuration in the ./configure script.
3309 Fixed to include xti.h on environments that has it.
3310 Patches by Carsten Ilchmann and andrew.
3312 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3314 * Changed the silc_id_create_client_id to be collision
3315 resistant. It is now assured that there cannot be created
3316 two same client ID's. I suspect that some weird bugs in
3317 the server were actually caused by duplicate Client IDs.
3318 Affected file silcd/serverid.[ch]. A router receiving
3319 new ID now also assures and informs the sending server
3320 if the ID caused collision.
3322 * Changed the silc_id_create_channel_id to also assure that
3323 there are no collisions.
3325 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3327 * Statement about ignoring the Mutual Authentication flag when
3328 performing rekey with PFS was a bit misleading. It is ignored
3329 if it was set in the initial negotiation, it cannot be even
3330 set in the rekey. Fixed in the ke-auth draft. Started the
3331 new versions of the protocol drafts in the doc/.
3333 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3335 * Fixed a bug in silc_client_command_identify_save when saving
3336 new channel information. The channel name was no duplicated
3337 and caused crash on exit. Affected file is
3338 lib/silcclient/command_reply.c.
3340 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3342 * Fixed the getkey command handling in the server. Send just
3343 empty OK reply to the sender if the key could not be fetched
3344 (but everything else was ok, like the key just was not available).
3345 Changed the public key parameter to optional in the protocol
3346 specs so that empty OK reply can be sent. Affected file
3349 Added a message to Irssi SILC client to tell to user if the
3350 server did not return a public key.
3352 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * Fixed a channel key regeneration bug. It registered new
3355 timeout tasks exponentially until all system resources were
3356 used. Affected file silcd/server.c.
3358 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3360 * Added the SILC Document generator to the scripts/silcdoc.
3361 It can be used to generate the Toolkit Reference Manual out
3362 of the source tree. Internally it will also use the RoboDoc
3363 generator now imported in util/robodoc.
3365 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3367 * Added couple of return's in rekey protocol if error orccurred
3368 during the protocol. The execution must be terminated.
3369 Affected file silcd/protocol.c. Also, terminate the protocol
3370 always with timeout.
3372 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3374 * The client's Client ID was created initally from the wrong
3375 nickname (it could have been in format nick@host) in the
3376 silc_server_new_client. Affected file silcd/packet_receive.c
3378 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3380 * Added some SILC_LOG_ERROR's to various error conditions
3381 if client could not be added to ID cache. Affected files
3382 silcd/packet_receive.c and silcd/server.c.
3384 * When client's sock->user_data is freed, NULL also the
3385 client->router and client->connection pointers. Added check
3386 for these pointers being NULL to various places around the
3387 code. Affected file silcd/server.c.
3389 * Added client->data.registered == TRUE checks to various
3390 places around the code to assure that unregistered client's
3391 are not handled when it is not allowed. Affected file
3394 * Added `bool registered' fields to all
3395 silc_idlist_[server|client]_get_* routines to indicate whether
3396 the fetched client needs to be registered or not. Affected
3397 file silcd/idlist.[ch].
3399 * Add your own entry as registered to the ID cache in the
3400 server. Affected file server.c.
3402 * Fixed a bug in silc_server_new_server. The SilcServer was
3403 set as the new server's context instead of SilcServerEntry.
3404 This naturally caused some weird bugs.
3406 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3408 * Do not delete the channel rekey task when adding it
3409 for in silc_server_create_channel_key.
3411 * Changed the silc_server_create_channel_key to return
3412 TRUE or FALSE to indicate the success of the channel key
3415 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3417 * Fixed MSVC++ project files and added missing files to
3418 Makefiles under win32/.
3420 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3422 * Do not add TCP_NODELAY flag if the operating system
3423 does not have it defined. Affected files are
3424 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3426 * Fixed buffer overflow from Irssi SILC Client. Affected
3427 file irssi/src/fe-common/core/themes.c.
3429 * Fixed double free in client library in the file
3430 lib/silcclient/client.c when disconnecting from server.
3432 * Applied double free patch from cras to Irssi SILC client.
3433 Affected files irssi/src/core/[modules/expandos].c
3435 * Fixed the disconnection handling to Irssi SILC Client.
3436 The application must call silc_client_close_connection
3437 in ops->connect client operation in case of failure of
3438 the connection. Affected file is
3439 irssi/src/silc/core/client_ops.c.
3441 * Do not set sock->protocol to NULL in the function
3442 silc_client_close_connection after executing the protocol's
3443 final callback since the sock might not be valid anymore.
3444 Affected file lib/silcclient/client.c.
3446 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3448 * Do not enable SILC_THREADS if the linking with libpthread
3449 did not happen. Affected file configure.in.pre.
3451 * Added notion to protocol specification that server must
3452 verify the sent authentication payload with CMODE when
3453 setting the channel founder key. Implemented it to the
3454 server. Affected file silcd/command.c.
3456 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3458 * Added _EXTRA_DIST SILC distribution variable to the
3459 distributions file. It is used to conditionally add extra
3460 files or directories to the specific distribution. Affected
3461 files ./prepare, Makefile.am.pre and distributions.
3463 Removed the `_' from the start of the distribution names.
3466 * Added README.WIN32 for instructions to compile the Toolkit
3469 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3471 * Fixed a double free in disconnection in the server. Affected
3472 file is silcd/server.c.
3474 * Fixed the lib/silcske/groups.c to work now also with GMP
3475 MP library. The string conversion did not work when using
3476 specific base and the base is indicated in the string as well.
3478 * Created win32/ directory which now includes MSVC++ specific
3479 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3480 It will appear only in the toolkit distribution
3482 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3484 * Changed the key material distribution function in case when
3485 the hash output is too short. The data is now concatenated
3486 a bit differently than it used to. Made the change to the
3487 SKE protocol specification.
3489 * Added better GMP detection to configure.in.pre. A patch
3492 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3494 * Fixed a minor bug in SKE that might cause some problem on
3495 some platforms. Affected file lib/silcske/silcske.c.
3497 * Added the cookie checking for initiator in the SKE. It checks
3498 that the responder returns the sent cookie unmodified. The
3499 affected file is lib/silcske/silcske.c. Added new SKE
3500 error type INVALID_COOKIE that can be sent during the
3501 negotiation. Fixed some memory leaks as well.
3503 * Added the "invalid cookie" error message to Irssi SILC client's
3506 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3508 * Added `task_max' field to the SilcClientParams to indicate
3509 the maximum tasks the scheduler can handle. If set to zero,
3510 default values are used. Affected file lib/silcclient/silcapi.h.
3512 * Fixed memory leaks in silc_client_close_connection. Affected
3513 file lib/silcclient/client.c.
3515 * Added silc_client_del_client_entry to client library to free
3516 all memory of given client entry. Affected file is
3517 lib/silcclient/idlist.[ch].
3519 * Added new functions silc_client_del_channel and
3520 silc_client_del_server to delete channel and server entries.
3521 Affected file lib/silcclient/[silcapi.h/idlist.c].
3523 * Removed silc_client_del_client_by_id from silcapi.h.
3525 * Fixed the INFO command to return the server's own info
3526 correctly when querying by Server ID. Affected file is
3529 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3531 * Removed the non-blocking settings in WIN32 code in the
3532 silc_sock_[read/write] and added SleepEx instead. Affected
3533 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3534 of input data is now checked with FIONREAD and ioctlsocket.
3536 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3538 * Call silc_schedule_task_del_by_context in the
3539 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3540 Affected file lib/silccore/silcprotocol.c.
3542 * Call silc_protocol_cancel for active protocols in the
3543 silc_server_close_connection if the funtion
3544 silc_server_free_sock_user_data has not been called.
3545 Affected file silcd/server.c.
3547 * Generic tasks cannot be deleted using the del_by_fd
3548 task deleting function since generic tasks does not match
3549 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3551 * Added a notion to SILCOPER help file that the SILCOPER works
3552 only on router server, not on normal server.
3554 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3556 * Added for WIN32 support for the new scheduler as well.
3557 Affected file lib/silcutil/win32/silcwin32schedule.c.
3559 * Fixed the SHA1 implementation to work on various platforms.
3561 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3563 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3564 API. It is part of the scheduler now. Everything else is
3565 as previously but some functions has changed their names.
3566 Checkout the lib/silcutil/silcschedule.h for the interface.
3567 Updated all applications to use the new interface. Affected
3568 files are lib/silcutil/silcschedule.[ch].
3570 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3572 * Found a bug in the SKE implementation. The HASH value,
3573 specified by the protocol, was not computed correctly. The
3574 public key of the responder was not added to the computation
3575 even though it is mandatory. Affected file lib/silcske/silcske.c.
3576 This unfortunately causes incompatibilities with older
3577 clients and servers.
3579 * Added WIN32 specific network init and uninit functions:
3580 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3581 the Winsock2. Affected file lib/silcutil/silcnet.h and
3582 lib/silcutil/win32/silcwin32net.c.
3584 * Set the socket always to nonblocking mode on WIN32 after
3585 reading data or writing data. Affected file is
3586 lib/silcutil/win32/silcwin32sockconn.c.
3588 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3590 * Fixed various compilation problems under WIN32. Affected
3591 files lib/silcutil/win32/silcwin32thread.c and
3592 lib/silcutil/win32/silcwin32schedule.c.
3594 * Removed all _internal.h #includes from public header
3595 files. Internal headers must never be included from
3598 Removed also the lib/silcske/payload_internal.h file.
3600 * All include files that may be needed (public and some others
3601 included by the public headers) by application developers are
3602 now copied to the ./includes directory. It does not copy any
3603 internal headers. Affected file Makefile.defines.pre and all
3604 Makefile.am's under lib/ and subdirs.
3606 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3608 * Do not change the ~/.silc directory's permissions automatically.
3609 Affected file irssi/src/silc/core/clientutil.c.
3611 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3613 * Do not cancel the protocol in silc_server_close_connection
3614 it might cause recursion. Now cancelled in the function
3615 silc_server_free_sock_user_data. Affected file silcd/server.c.
3617 * Fixed the silc_server_remove_clients_by_server to regenerate
3618 the channel keys correctly finally. Added also new function
3619 silc_server_remove_clients_channels to actually do it.
3620 Affected file silcd/server.c.
3622 * Fixed the silc_server_new_channel to not crash by giving
3623 wrong router to the new channel. Affected file is
3624 silcd/packet_receive.c.
3626 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3628 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3629 which is given as argument to the silc_client_alloc now.
3630 It can be used to configure the client and set various parameters
3631 that affect the function of the client.
3633 * The USERS command in server did not check whether the channel
3634 is private or secret. Affected file silcd/command.c.
3636 * Added new argument to the USERS command in protocol specification.
3637 The USERS command now can take the channel name as argument
3638 as well. Added support for this in client and server and
3639 updated the protocol specs.
3641 * Completed the GETKEY command in client. It can be now used
3642 to fetch also servers public key not only some clients.
3643 Affected files lib/silcclient/command[_reply].c.
3645 * Added silc_client_get_server to return server entry by the
3646 server name. Affected files lib/silcclient/silcapi.h and
3649 * Redefined the IDENTIFY command in protocol specification to be
3650 more generic. It now can be used to query information about
3651 any entity in the SILC Network, including clients, servers and
3652 channels. The query may be based either the entity's name
3653 or the ID. Added support for this in both client and server.
3655 Affected files silcd/command.c and lib/silcclient/command.c
3656 and command_reply.c.
3658 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3659 the _from_client and _from_server functions. Affected file
3662 * Added silc_client_get_channel_by_id_resolve to the file
3663 lib/silcclient/silcapi.h to resolve channel information by
3664 its ID. Added also silc_client_get_channel_by_id that
3665 does not resolve it from the server.
3667 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3669 * Added SilcServerEntry context into the client library
3670 to represent one server. The INFO command now allocates
3671 these to save the resolved server info. For now on the
3672 client library will also keep information about servers,
3673 connected and resolved with INFO.
3675 The INFO command now allocates the SilcServerEntry context
3676 and saves the server info there. The COMMAND_REPLY in
3677 the INFO now returns the parameters to application in
3678 same order as defined in the protocol specification.
3680 The entries are cached in the client->server_cache.
3682 * The INFO command is now issued after received the Client ID
3683 from the server. Affected file lib/silcclient/client.c.
3685 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3686 to the application as the mode changer might be server.
3687 It is guaranteed that NULL is not returned anymore to the
3688 application. Affected file lib/silcclient/client_notify.c.
3690 The ID Type is now also passed to the application so that
3691 it can check whether the returned entry is SilcClientEntry
3694 Added new function silc_client_get_server_by_id to return
3695 the server entry by ID. Affected files are the
3696 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3698 * Do not create the channel in the Irssi SILC Client when issuing
3699 the JOIN command but when received the sucessful JOIN command
3700 reply. Otherwise the channel might get created even though we
3701 could not join it. The Affected file is
3702 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3704 * Fixed a channel joining bug in router. The router must also
3705 check the channel modes, invite and ban lists etc. when serving
3706 the JOIN command sent by normal server. Affected file is
3707 silcd/command.c. The router now resolves the client's
3708 information from the server who sent the JOIN command if it
3709 does not know it, and processes the JOIN command only after
3712 * Changed the SilcCommandCb to take new argument; void *context2.
3713 Affected file lib/silccore/silccommand.h
3715 The second argument in the command callbacks in the server now
3716 includes the SilcServerCommandReplyContext if the command was
3717 called as pending command callback from the command reply.
3718 Otherwise it is NULL. When called as pending the status of the
3719 command reply will be checked and if it was erronous the
3720 error will be sent to the original sender of the command.
3721 This way the client always receives the error messages even
3722 though the server was actually the one who received the error
3723 when it resent the command to router, for example. Affected
3724 files silcd/command[_reply].[ch].
3726 * Fixed sending WHOWAS command's error message to client if
3727 the requested client could not be found. It was missing.
3730 * Changed the CMODE and CUMODE commands reply arguments in the
3731 protocol specification. The Channel ID is now sent in both
3732 of the commands to identify the channel. Implemented this
3733 new feature to the client and server. Affected files
3734 lib/silcclient/command_reply.c and silcd/command.c.
3736 * Made better checks for invite and ban lists in the JOIN
3737 command in server. Affected file silcd/command.c.
3739 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3741 * The server now performs the incoming host IP/DNS lookup
3742 using the silc_socket_host_lookup and thus does not block
3743 the server anymore. Affected file silcd/server.c.
3745 * Completed the multi-thread support for SILC Scheduler in
3746 the lib/silcutil/silcschedule.c.
3748 * Fixed the configure.in.pre to detect the pthread correctly
3751 * Fixed a deadlock in silc_task_queue_wakeup in the file
3752 lib/silcutil/silctask.c.
3754 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3756 * Added new function silc_schedule_wakeup that is used in
3757 multi-threaded environment to wakeup the main thread's
3758 schduler. It needs to be used when a thread adds a new task
3759 or removes a task from task queues. After waking up, the
3760 scheduler will detect the task queue changes. If threads
3761 support is not compiled in this function has no effect.
3762 Implemented the wakeup mechanism to both Unix and WIN32
3763 systems. Affected files are lib/silcutil/silcschedule.[ch],
3764 lib/silcutil/unix/silcunixschedule.c and the
3765 lib/silcutil/win32/silcwin32schedule.c.
3767 * Added new function silc_task_queue_wakeup to wakeup the
3768 scheduler by the specified task queue. Affected file
3769 lib/silcutil/silctask.[ch].
3771 * The silc_socket_host_lookup_start now wakes up the scheduler
3772 after adding the timeout task. Affected file is
3773 lib/silcutil/silcsockconn.c.
3775 * The silc_socket_host_lookup is synchronous now if the threads
3776 support is not compiled in. However, the callback is still
3777 called asyncronously through the scheduler, anyway. Affected
3778 file lib/silcutil/silcsockconn.c.
3780 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3782 * Added new function silc_socket_host_lookup to perform
3783 asynchronous IP and FQDN lookups for the socket connection.
3784 Affected files lib/silcutil/silcsockconn.[ch].
3786 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3788 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3789 that may or may not compile the mutex support in.
3791 Changed the silc_mutex_alloc interface. It allocates the
3792 mutex now to the sent pointer and returns TRUE or FALSE.
3794 Affected file lib/silcutil/silcmutex.h.
3796 * Wrote the SILC Task Queue interface to support multi-threads.
3797 Affected file lib/silcutil/silctask.[ch].
3799 * Wrote the SILC Scheduler to support multi-threads. Affected
3800 file lib/silcutil/silcschedule.c.
3802 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3804 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3805 in lib/silcutil/win32/.
3807 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3809 * Defined SILC Mutex API and SILC Thread API and implemented
3810 them for Unix. Affected files are
3811 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3812 lib/silcutil/unix/silcunixmutex.c and
3813 lib/silcutil/unix/silcunixthread.c.
3815 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3817 * Fixed the silc_server_remove_clients_by_server's channel
3818 key re-generation. The hash table handling was incorrect
3819 and would not work with many channels. Affected file is
3822 * Fixed some memory leaks around the server code.
3824 * Rewrote the silc_server_get_users_on_channel to support IPv6
3825 based Client ID's. Affected file silcd/server.c.
3827 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3828 specification. However, a separate document must be written
3829 to define the detailed signing procedure and the payload
3830 associated with the flag. Defined the flag to the
3831 lib/silccore/silcchannel.h as well.
3833 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3835 * Changed the dynamic tables to static size tables in the
3836 lib/silccrypt/silchmac.c.
3838 * Removed GCC dependencies from the code. A patch by cras.
3840 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3842 * Do not show the error "Error receiving packet bla bla"
3843 in server if it really was not an error (-2 means that reading
3844 is pending). Affected file silcd/server.c.
3846 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3848 * Fixed a possible crash in silc_server_remove_clients_by_server
3849 in silcd/server.c. Fixed there also some memory leaks.
3851 * Fixed the silc_idlist_replace_client_id. It could replace
3852 wrong key in the hash table. Affected file silcd/idlist.c.
3854 * Do not check whether there are global users on the channel
3855 if the channel->global_users is FALSE. Affected functions
3856 silc_server_remove_from_one_channel and
3857 silc_server_remove_from_channels in silcd/server.c. Also,
3858 do not check if the removed client is local as we can be
3859 sure that global client was not removed from the channel
3860 and checking for global users is not needed.
3862 * The silc_server_remove_clients_by_server now re-generates
3863 the channel keys correctly for those channels that had
3864 clients removed from them. Affected file silcd/server.c.
3866 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3868 * Found the reason of random crashes in the server. We weren't
3869 ignoring the SIGPIPE signal (which can be sent in write())
3870 and it crashed the server. Affected file silcd/silcd.c.
3872 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3874 * Assure that sock->user_data is not NULL in the function
3875 silc_server_packet_send in silcd/packet_send.c.
3877 * Disconnect the remote connection if it could not be added
3878 to any ID lists in the server. The affected file is
3881 * Check in silc_server_packet_send[_real/dest] that the
3882 socket is not disconnecting and ignore the data if it is.
3883 Affected file silcd/packet_send.c.
3885 * Define inline to __inline on native WIN32 compilation.
3886 Affected file includes/silcwin32.h.
3888 * Added some explicit type casts for inline code since MSVC
3889 require them. Affected files lib/silcutil/silcbuffer.h,
3890 lib/trq/silcdlist.h and lib/trq/silclist.h.
3892 * Print warning in log files from now on if the packet
3893 decryption fails. Affected file silcd/server.c.
3895 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3897 * Changed the `say' client operation's interface to accept
3898 new `type' argument to indicate the type of the message sent
3899 by the library. The application may filter the library's
3900 messages according the type. The affected file is the
3901 lib/silcclient/silcapi.h.
3903 * Added two new functions to lib/silcclient/silcapi.h:
3904 silc_client_del_client and silc_client_del_client_by_id.
3905 Affected file lib/silcclient/idlist.c.
3907 * Moved the clientincludes.h from includes/ to silc/ and
3908 serverincludes.h from includes/ to silcd/.
3910 * The modes for the CMODE and CUMODE are now passed as
3911 uint32 for application with COMMAND_REPLY. The affected
3912 file is lib/silcclient/command_reply.c.
3914 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3916 * /WHOIS without arguments shows client's own information.
3917 Affected file lib/silcclient/command.c.
3919 * Changed PING to not accept any arguments. The specs
3920 says that client can ping only the connected server so
3921 requiring an argument is not needed. Affected file is
3922 lib/silcclient/command.c.
3924 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3926 * Fixed a fatal bug in private message sending and reception
3927 encryption and decryption when using private message keys.
3928 The implementation was incorrect and did not follow the
3929 specification. It causd that some of the message were
3930 lost since it did not use the sending and receiving keys
3931 as the protocol suggests. This has been fixed and will cause
3932 incompatibilities with older clients when sending private
3933 message encrypted with private message keys. Affected files
3934 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3935 and various other in Irssi SILC Client.
3937 Added `responder' boolean argument to the functions
3938 silc_client_add_private_message_key[_ske] to indicate when
3939 the key is added as responder or initiator of the key
3942 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3944 * Removed the silc_ske_check_version function and created
3945 a SilcSKECheckVersion callback. Added also a function
3946 silc_ske_set_callbacks that is now used to set all SKE
3947 callbacks. The callback functions are not given to
3948 the SKE functions anymore, but this function is used to
3951 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3953 * Added `silc_version' argument to the silc_client_alloc
3954 to define the version of the application for the library.
3955 The library will use the version string to compare it
3956 against the remote host's (usually a server) version
3957 string. Affected file lib/silcclient/silcapi.h
3959 * Added the KE protocol context to Key Agreement context
3960 in client library so that we can abort the SKE if it
3961 is in process when we get timeout. Affected file is
3962 lib/silcclient/client_keyagr.c.
3964 * Do not resolve the client ID forever if it returns in the
3965 first time that such client does not exist. This was done
3966 for example with private message. Affected file is
3967 lib/silcclient/client_prvmsg.c.
3969 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3971 * Do not add regex.h for WIN32. The affected file
3972 includes/silcincludes.h.
3974 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3975 not work yet 100%. It generates the DLL's automatically
3976 when compiling with --with-win32 under cygwin.
3978 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3980 * lib/contrib/regex.c is not compiled on WIN32.
3982 * Added silc_net_get_socket_opt function to the
3983 lib/silcutil/silcnet.h.
3985 * Added includes/silcwin32.h for WIN32 specific includes
3988 * Do not use ptime structure or any of the posix process
3989 functions on WIN32 in lib/silccrypt/silrng.c.
3991 * Added silc_gettimeofday to provide generic function
3992 for struct timeval on all platforms. Added the function
3993 to lib/silcutil/silcutil.h.
3995 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3997 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3998 library as they clearly belong there. As a plus side we
3999 can make the actual socket connection routines platform
4002 Added also new generic function silc_socket_read and
4003 silc_socket_write (that used to be silc_packet_[read/write].
4004 The implementation of these are platform specific.
4006 * Added WIN32 specific routines of silc_socket_[read/write]
4007 to lib/silcutil/win32/silcwin32sockconn.c.
4009 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4011 * Added preliminary support for native WIN32 compilation under
4012 cygwin (using the -mno-cygwin option for GCC) to the
4013 ./configure.in.pre. The --with-win32 now prepares the
4014 compilation for native WIN32.
4016 * Rewrote the SILC Scheduler interface in the file
4017 lib/silcutil/silcschedule.h. The scheduler is now context
4018 based and does not have anymore any global static scheduler.
4019 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4020 and created lib/silcutil/win32 directory for WIN32 based
4023 * Added Unix specific network routines to the
4024 lib/silcutil/unix/silcunixnet.c and the old
4025 lib/silcutil/silcnet.c includes now only generic routines.
4027 Added WIN32 specific network routines to the
4028 lib/silcutil/win32/silcwin32net.c.
4030 * Added Unix specific utility functions from the
4031 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4033 * Added WIN32 SILC Scheduler to the file
4034 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4037 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4039 * Do not handle JOIN notify in the server if the target client
4040 is not registered (idata->registered == FALSE). The affected
4041 file is silcd/packet_receive.c.
4043 * Update the nickrec->founder in event_cumode in the Irssi SILC
4044 client. Affected file irssi/src/silc/core/silc-channels.c.
4046 * Fixed the CUMODE_CHANGE notify handling in the server when
4047 server and router are announcing their clients on channels.
4048 Now the mode changes are saved and notified correctly. The
4049 affected file is /silcd/packet_receive.c.
4051 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4052 They really did not replace the cache entry in the ID Cache.
4053 Now they do that. Affected file silcd/idlist.c.
4055 * Fixed the KICK notify handling in the Irssi SILC client to
4056 update the channel records so that the kicked client does not
4057 appear to be on the channel. The affected file is
4058 irssi/src/silc/core/silc-channels.c.
4060 * Always update the conn->current_channel when executing command
4061 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4063 * Fixed the KILL notify handling in Irssi SILC client to remove
4064 the killed client on all channels.
4066 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Fixed the silc_parse_command_line to remove extra spaces
4069 from the start and end of the arguments. Affected file is
4070 lib/silcutil/silcutil.c.
4072 * Cancel and free any active protocol in the function
4073 silc_server_close_connection. Affected file silcd/server.c.
4075 * Cancel and free any active protocol in the function
4076 silc_client_close_connction. Affected file is
4077 lib/silcclient/client.c.
4079 * Do not execute the KILL command for clients that are in
4080 history (ie. they are not in the network). Affected file is
4083 * Fixed KILL notify handling, client does not crash anymore.
4084 Affected file irssi/src/silc/core/silc-channels.c.
4086 * Reduced the default packet buffer size from 2048 to 1024 in
4087 lib/silccore/silcpacket.c.
4089 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4090 counter to the SKE context that is incresed when the SKE library
4091 performs async operation outside the library. If the outside
4092 process frees the SKE context and FREED status will be set
4093 and the library will detect after the sync operation that the
4094 libary is freed. The affected files are
4095 lib/silcske/silcske[_status].[ch].
4097 * Resolve the client entry information in the function
4098 silc_client_channel_message to assure that NULL pointer is not
4099 passed as client entry to the application. */
4101 * Fixed the task timeout calculation to assure that there is
4102 never negative timeouts. The affected file is
4103 lib/silcutil/silcschedule.c.
4105 * Fixed the channel user mode notification sending in server.
4106 It was sent point-to-point to the router (or to server by router)
4107 but it needs to be destined to a channel. The routines now
4108 supports sending the channel user mode notifys to the channels
4109 when announcing clients and channels. Affected files are
4110 silcd/server.c and silcd/packet_receive.c.
4112 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4113 It did not actually replace the old channel entry in the cache.
4114 Affected file lib/silcclient/client_notify.c.
4116 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4118 * Fixed a possible crash in silc_packet_send_prepare. It now
4119 assures always that there is enough space in the buffer and
4120 at the tail area of the buffer (for MAC).
4122 Fixed the inbound buffer reallocation in silc_packet_read.
4123 It was old code and did not handle the reallocation correctly.
4126 The affected file is lib/silccore/silcpacket.c.
4128 * Fixed buffer overflow in silc_parse_nickname in the file
4129 lib/silcutil/silcutil.c.
4131 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * make install generates new server keys only if there is not
4136 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4139 Added check that if the NOREPLY is set then we will not send
4140 the away message. This avoids infinite loop of away messages
4141 if both clients are away. The affected file is
4142 lib/silcclient/client_prvmsg.c.
4144 * Fixed client crash if /NICK was given without arguments.
4145 Affected file lib/silcclient/command.c.
4147 * Server does not send the invite list in INVITE command back
4148 to the client if the list was not altered. Added this notion
4149 to the protocol spec as well. Affected file silcd/command.c.
4151 Fixed possible crash in INVITE command by checking the
4152 value of silc_server_get_client_route command.
4154 * Fixed the INVITE notify type handling. The arguments are now
4155 taken in correct order and client does not crash. The affected
4156 file is irssi/src/silc/core/silc-channels.c.
4158 Removed the "Inviting xxx to channel" message from the
4159 client library away and let the application handle it.
4160 Affected file lib/silcclient/command.c. Added that message
4161 to Irssi SILC client's message formats.
4163 * Fixed CMODE command crash in client. It now checks the
4164 amount of arguments correctly and does not crash. The affected
4165 file is lib/silcclient/command.c.
4167 * Do not create new channel automatically in silc_channels_join
4168 but check whether the channel by that name already exists.
4169 Affected file irssi/silc/core/silc-channels.c.
4171 * Do not send the SERVER_SIGNOFF to router if the disconnected
4172 entity was the router. Affected file silcd/server.c.
4174 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4175 SILC client as it was missing from there.
4177 Added the handling of the KICK notify to the Irssi SILC client
4178 as it was missing. Added "you have been kicked" message to
4179 Irssi SILC client's message modules formats.
4181 Added the handing of the KILL notify to the Irssi SILC client
4182 as it was missing. Added the kill message module formats
4185 The affected file is irssi/src/silc/core/silc-channels.c.
4187 * The router did not save the channel mode the server announced.
4188 Affected file silcd/packet_receive.c.
4190 * Fixed a possible crash in INFO command in server. If the
4191 server did not provide the server info it crashed. Affected
4192 file silcd/command.c.
4194 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Fixed the GETKEY command in the server to check also the
4197 global list. Otherwise the GETKEY would not work correctly
4198 in normal SILC server. Affected file silcd/command.c.
4200 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Fixed GETKEY crash, it crashed if the command did not succseed.
4204 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4207 is now real and not just an macro interface to GMP.
4209 Removed the entire GMP from the source tree and imported new
4210 NSS MPI library instead. Reason for removing GMP is that it is
4211 extremely large and compiles extremely slow. The NSS MPI
4212 is only a few files and compiles in less than 10 seconds.
4213 The speed is also about the same as GMP. The MPI is imported
4214 to lib/silcmath/mpi.
4216 If the system has GMP installed we will still use the GMP.
4217 If it is not then the NSS MPI will be compiled.
4219 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * Merged a long nickname (127 characters long) crash bugfix from
4222 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4224 * Merged a freed memory reference bugfix from Irssi CVS tree.
4225 Affected file irssi/src/core/commands.c.
4227 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4229 * Added the server's public key sving and verification to the
4230 server when performing the SKE. This was missing and the
4231 remote server's (or router's) public key was accepted without
4232 checking whether we have it previously or trust it at all.
4233 Affected file silcd/protocol.c.
4235 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Check in the silc_server_timeout_remote if protocol is active
4238 and make sure that the protocol's final callback is called so
4239 that all memory if freed. Affected file silcd/server.c.
4241 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * silc_server_whois_send_reply crashed the server if the nickname
4244 was 127 characters long. Affected file silcd/command.c.
4246 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4248 * Added sanity check to the silc_server_new_client. If the hostname
4249 is provided inside username then check that the provided hostname
4250 really is the same as the resolved one. If the hostname was not
4251 resolved then check it from the public key. Affected file is
4252 silcd/packet_receive.c.
4254 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4255 if the server disconnected us and the connection is not valid
4256 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4258 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4259 the library to the lib/silcutil/silcutil.[ch].
4261 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Close log file after open. Affected file
4264 lib/silcutil/silclog.c.
4266 * Check whether sock == NULL in silc_client_send_packet and return
4267 if it is. Affected file lib/silcclient/silcclient.c.
4269 * Check rec->entry == NULL in the Irssi SILC Client before
4270 sending the channel message. Affecte file is
4271 irssi/src/silc/core/silc-servers.c.
4273 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Merged a splitted window bugfix from Irssi CVS tree. The
4276 affected file is irssi/src/fe-text/textbuffer-view.c.
4278 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4279 It did not print nickname.
4281 * Improved the distributions system a bit.
4283 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4286 irssi/src/fe-text/gui-window.c.
4288 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4289 to in-active server. The affected file is
4290 irssi/src/silc/core/client_ops.c.
4292 * Resolve the client in USERS command reply if the entry does
4293 not have username resolved. The affected file is
4294 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4295 command to WHOIS command to really resolve stuff. The USERS
4296 is not used any more in any critical section so WHOIS can
4297 be used even though it might be slower than IDENTIFY.
4299 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4302 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Changed the protocol API a bit more consistent in the
4305 lib/silccore/silcprotocol.[ch].
4307 * Changed the following headers to ROBODoc format:
4309 lib/silccore/silcpayload.h
4310 lib/silccore/silcprotocol.h
4311 lib/silccore/silcsockconn.h
4313 All core library headers are now formatted.
4315 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Fixed a bug in Irssi SILC client; do not show that you are
4318 server/router operator if you really are not. Affected file is
4319 irssi/src/silc/core/client_ops.c.
4321 * Renamed silc_command_free_payload to silc_command_payload_free.
4322 Affected file lib/silccore/silccommand.h
4324 * Added silcmath.h to include the prototoypes of various routines
4325 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4328 * Changed the following headers to ROBODoc format:
4330 lib/silccore/silcchannel.h
4331 lib/silccore/silccommand.h
4332 lib/silccore/silcid.h
4333 lib/silccore/silcidcache.h
4334 lib/silccore/silcmode.h
4335 lib/silccore/silcnotify.h
4336 lib/silccore/silcpacket.h
4337 lib/silcmath/silcmath.h
4339 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Added checking to the server code not to start the server if
4342 ciphers and stuff are not configured properly. Affected files
4343 silcd/serverconfig.[h] and silcd/server.c.
4345 * Changed the layout of the header files of the public interfaces
4346 in the SILC libraries. The new layout supports ROBODoc
4347 documentation tool (and some others) so that it is easy to create
4348 a library reference manual. All the other headers and source
4349 code must still follow the CodingStyle document. Also source
4350 code must not include these ROBODoc stuffs, only the headers.
4351 Furthermore, all public interface headers must now be named
4352 by using `silc' prefix, example: silcapi.h, silccipher.h.
4353 Some files were renamed due to this. All the other headers
4354 must not be used as public interfaces. I will update the
4355 CodingStyle document later. Changed following headers, so far:
4357 lib/silcclient/silcapi.h
4358 lib/silccore/silcauth.h
4359 lib/silccore/silcprivate.h
4360 lib/silccrypt/silcdh.h
4362 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Removed silc_client_packet_send_flush from the client library
4367 as it is not needed. Affected file lib/silcclient/client.[ch].
4369 * Added printing of message of unresolved authentication method
4370 to the Irssi SILC client. Added it to the module formats.
4371 Removed the same message from the client library.
4373 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Added new distribution feature, DISTLABEL. Every distribution
4376 can define own preprocessor label that can be used in the
4377 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4378 file distributions, acconfig.h.pre and prepare.
4380 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4382 * Added Makefile.defines_int to include the actual definitions
4383 for Makefile.defines.in. Tested the new distribution system,
4384 created distributions and tested installation.
4386 * Added AWAY message printing to the Irssi SILC client. Added
4387 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4389 * Added SCONNECT command to call the SILC's CONNECT command.
4390 Cannot use CONNECT directly since Irssi uses that internally.
4391 Affected file irssi/src/silc/core/silc-servers.c.
4393 Added ACTION local command. It is same as ME command but takes
4394 the channel as mandatory argument.
4396 Rewrote some of the Irssi's help files to suite for SILC
4399 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Added Makefile.defines[.in] that should for now on be included
4402 in all Makefile.am file in the source tree. That file includes
4403 all common compilation definitions for SILC source tree.
4405 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Minor changes to the ./prepare script to change the package
4408 name according the distribution name to the configure.in.
4410 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Created new distribution system. Added file `distributions'
4413 that defines all the distributions that can be created out of
4414 the SILC source tree. The ./prepare script now reads that
4415 file to determine how to prepare the distributions. The
4416 first argument to the ./prepare is the name of the distribution
4417 and second is the version of the distribution. If given
4418 without arguments it creates the default (toolkit) distribution
4419 with the default version (defined in ./prepare).
4421 All Makefile.am files that are subject to the distributions
4422 are now named as Makefile.am.pre. These are ./Makefile.am
4423 and lib/Makefile.am. Others may be changed later.
4425 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Added invite list, ban list, some key management and connection
4428 error message printing to module formats in the Irssi SILC client.
4430 * Added new silc_client_set_away_message to set the away message
4431 that is back to the person who sent private message. The
4432 affected file lib/silcclient/silcapi.h and the
4433 lib/silcclient/client_prvmsg.c.
4435 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4437 * Fixed the private message sending in the Irssi SILC client,
4438 added local command KEY to the Irssi SILC client.
4440 Added key management and key agreement message formats to the
4441 irssi/src/fe-common/silc/module-formats.[ch].
4443 Added USERS (alias WHO) printing, server/router operator
4444 indication and LIST command printing to the module formats.
4446 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4448 * Fixed channel joining notify handling, cumode notify handling
4449 from Irssi SILC client.
4451 * Added SILC specific module-formats to the Irssi SILC client so
4452 that SILC specific message hilighting, colors etc is possible.
4453 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4455 Added channel mode, channel user mode, actions, notices,
4456 whois and whowas printing to the the module-formats.c.
4458 * Fixed a bug in channel deletion in the server. The channel
4459 is not left to the cache even if the channel founder auth mode
4460 is set when there are no users anymore on the channel. Affected
4461 file silcd/server.c.
4463 * The silc_net_localhost now resolves the entire hostname including
4464 the domain name. Affected file lib/silcutil/silcnet.c.
4466 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Changed the ask_passphrase client operation to be ascynchronous.
4469 It has now a completion callback and a context that the
4470 application must call after it has got the passphrase from
4471 the user. Affected files lib/silcclient/silcapi.h,
4472 lib/silcclient/protocol.c, lib/silcclient/command.c and
4475 Added SilcAskPassphrase callback that the application calls
4476 to deliver the passphrase to the library.
4478 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4479 The public key verification and especially a certificate
4480 verification is asynchronous procedure.
4482 Added new SILC_SKE_STATUS_PENDING status to indicate the
4483 request is pending and a callback will be called to finalize
4486 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4487 indicate that remote end did not send its public key (or
4488 certificate), even though we require it. Added check for this
4489 condition in the SKE. This was a security bug, now fixed.
4491 Defined new SilcSKEVerifyCbCompletion callback that is called
4492 when the verification process is completed.
4494 The affected files lib/silcske/silcske_status.h and
4495 lib/silcske/silcske.[ch].
4497 * Changed the verify_public_key client operation to be async
4498 as well. Defined SilcVerifyPublicKey callback that is used to
4499 indicate the success of the public key verification process.
4501 Changed the server and client to use the new async client
4504 * Changed the Irssi SILC client's internal scheduler to be called
4505 twice as many times as it used to be. As a result the client
4506 should be a bit faster now. Affected file is
4507 irssi/src/silc/core/silc-core.c.
4509 * Added support to Irssi SILC client of asynchronous public key
4510 verification and passphrase inquiry. Affected file is
4511 irssi/src/silc/core/silc-core.c.
4513 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Do not say "You have left channel %s" in client library.
4516 Moved it to the application. Affected files are
4517 lib/silcclient/command.c and silc/client_ops.c.
4519 * Fixed silc_client_get_clients. Command context was not
4520 duplicated and was freed memory in the callback. Affected
4521 file lib/silcclient/idlist.c.
4523 * Do not say "you are now talking..." on JOIN command in the
4524 client library. The appliation must handle it.
4526 * Do not say ".. changed topic to" in command reply in the
4527 client libary. The application must handle it.
4529 * Fixed TOPIC command sending in the client library.
4531 * Fixed a memory leak in silc_client_command_free in the file
4532 lib/silcclient/command.c.
4534 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Imported a modified version of Irssi client to the source tree.
4537 The Irssi will be used to create a new client called
4538 Irssi SILC. Imported to irssi/.
4540 Added silc_core_init_finish function to the Irssi. Affected
4541 file irssi/configure.in.
4543 A lot changes in the Makefile.ams around the irssi tree.
4545 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Do not rehash if the new size is same as the old size of the
4548 hash table, in the silc_hash_table_rehash*. The affected file
4549 lib/silcutil/silchashtable.c.
4551 * Replaced hash_table_del_by_context calls from the server
4552 (when channel->user_list and client->channels) to the
4553 hash_table_del as it is sufficient and faster.
4555 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4557 * Added silc_hash_table_list, silc_hash_table_get and the
4558 SilcHashTableList structure to provide an alternative way to
4559 traverse the hash table. The affected files are
4560 lib/silcutil/silchashtable.[ch].
4562 * Changed the server's idlist routines to use the hash table
4563 routines to optimize the code.
4565 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Replaced the client entry's `channel' list and channel entry's
4568 `user_list' list to hash tables for optimized lookup. Changed
4569 the code to use the hash table interface around the code.
4570 Affected file lib/silcd/idlist.[ch].
4572 * Added `auto_rehash' boolean argument to the function
4573 silc_hash_table_alloc to indicate whether the hash table should
4574 auto-rehash when it thinks is appropriate time. It will
4575 increase the hash table size if the there is twice as much
4576 entries in the table than the size of the table, and will
4577 decrease the size if there are twice as less entries than
4578 the size of the table.
4580 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4584 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * silc_idcache_purge_by_context deletes the entry now by context
4587 as it is supposed to do. Affected file lib/silccore/idcache.c.
4589 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4590 client is not anymore valid (WHOWAS givens the info) and not
4591 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4593 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Removed the `data' and `data_len' arguments from the ID Cache
4596 interfaces and added `name' argument. ID Cache does not handle
4597 anymore the binary data only a names associated with given ID.
4599 * When hashing a Client ID with silc_hash_id the entire ID is
4600 not hashed anymore, instead only the hash of the Client ID is
4601 hashed. This way we can access the Client ID from the cache
4602 with Client ID but with the hash of the ID (which is a hash of
4603 the nickname) as well without any difference in performance.
4605 Added also silc_idcache_find_by_id_one_ext to do one on one
4606 searching when we have the actual ID. Added also function
4607 silc_hash_client_id_compare. The affected files are
4608 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4610 * When hashing the name associated with a ID it is always done
4611 in lowercase. This way we can access the cache without worrying
4612 about case-sensitivity, even though, for example nicknames are
4615 * Fixed a bug in server with channel message sending. It put
4616 wrong ID type as destination ID. The affected file
4617 silcd/packet_send.c.
4619 * silc_idcache_del_by_context now deletes from all hash tables
4620 by context. Affected file lib/silccore/idcache.c.
4622 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Changed the client library to use the new ID Cache interface.
4625 Changes around the source tree.
4627 * Added silc_hash_table_rehash_ext to rehash with specific
4628 hash function. Affected file lib/silcutil/silchashtable.[ch].
4630 * Added silc_hash_string_compare to compare two strings in the
4631 hash table. Affected file lib/silcutil/silcutil.[ch].
4633 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4635 * Added new function silc_idcache_del_by_context into the
4636 lib/silccore/idcache.[ch].
4638 * Changed the server's ID list routines to use the new ID Cache
4639 interface. Changes around the source tree.
4641 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Added silc_hash_table_del[_by_context]_ext functions in to the
4644 lib/silcutil/silchashtable.[ch].
4646 Removed silc_hash_table_find_all* routines and added new
4647 silc_hash_table_find_foreach to replace them.
4649 Added silc_hash_table_replace_ext function as extended
4650 replacing function. Separated the simple hash table interface
4651 from the extended hash table interface in the file
4652 lib/silcutil/silchashtable.h.
4654 * Fixed minor bugs and changed it to use some of the new
4655 hash table functions in lib/silccore/idcache.c
4657 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Added new function silc_hash_table_find_all to return all keys
4660 in the hash table by the specified key. As the hash table is
4661 collision resistant it also makes it possible to have several
4662 duplicate keys in the hash table. This function may be used to
4663 find all of the keys from the hash.
4665 Added user_context arguments to the SilcHashFunction,
4666 SilcHashCompare and SilcHashDestructor to deliver user specified
4669 Added new fuctions silc_hash_table_find[_all]_ext to do
4670 extended lookup with specified hash and compare functions and
4671 specified user contexts.
4673 Added new function silc_hash_table_add_ext to add the key
4674 with specified hash function and user context.
4676 Added new function silc_hash_table_foreach to traverse all
4677 entrys in the hash table. Added SilcHashForeach callback
4680 Added new function silc_hash_table_del_by_context to delete
4681 the entry only if the context associated with the key matches.
4683 Affected files are lib/silcutil/silchashtable.[ch].
4685 * Removed silc_hash_[server/client/channel]_id and added just
4686 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4687 silc_hash_id_compare to compare two ID's using as the hash table
4688 comparison function. Added also silc_hash_data to hash
4689 binary data and silc_hash_data_compare to compare it.
4691 * Removed silc_idlist_find_client_by_hash as it is not needed
4692 anymore. Affected file silcd/idlist.[ch].
4694 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4695 to use internally the SilcHashTable. The new ID Cache is a lot
4696 faster than the old one. Some of the ID Cache interface was also
4697 rewritten and obsolete and stupid functions were removed.
4699 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Added entry_count field to the SilcHashTable to keep the number
4702 of the entries in the table. Implemented the function
4703 silc_hash_table_rehash. Added new function
4704 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4706 Fixed a minor bug in silc_hash_table_free.
4708 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4709 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4710 into the lib/silcutil/silcutil.[ch].
4712 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Implemented a collision resistant hash table into the
4715 lib/silcutil/silchashtable[ch]. See the header and the source
4716 for the SilcHashTable API.
4718 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4720 * Merged dotconf version 1.0.2 into lib/dotconf.
4722 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Do not compile anything in lib/silcsim/* if the SIM support
4725 is not enabled. The tree should now compile without problems
4728 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Compiled the SILC under cygwin. Compiled and tested briefly
4731 without problems. More tests needed. The SIMs didn't compile
4734 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4736 * Fixed possible crash in silc_get_username in the
4737 lib/silcutil/silcutil.c.
4739 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Fixed a va_arg in silc/client_ops.c.
4743 * Oops, RC5 routines were named AES and caused some problems
4744 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4746 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4748 * Added new SilcIDIP structure into the lib/silccore/id.h and
4749 replaced the old `ip' fields from all SILC ID's to that type.
4750 This is a step towards IPv6 support.
4752 The silc_id_get_len takes now the ID as an extra argument.
4753 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4754 both IPv4 and IPv6 based ID's.
4756 The affected files are lib/silccore/id.[ch] and other files
4757 around the tree using these routines.
4759 * Removed the ID length arguments in server from various
4760 silc_server_send_notify_* routines -> they are not needed
4763 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Fixed memory leak in silc_encode_pem_file in the file
4766 lib/silcutil/silcutil.c.
4768 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Check minor version as well in the SKE. Affected files are
4771 silcd/protocol.c and lib/silcclient/protocol.c.
4773 * Added --identifier option to the server so that an identifier
4774 can be when creating the public key for the server. Affected
4775 file is silcd/silcd.c.
4777 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4778 lib/silccrypt/silcpkcs.c.
4780 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * Register default ciphers and stuff when using -C option with
4783 the server. Affected file sildc/silcd.c.
4785 * Put back the servers public key filename format, it is better
4786 than the new one. For now, the client keys are saved with the
4787 new filename format. The affected file silc/client_ops.c.
4789 * Implemented the Cipher API for the rest of the ciphers that
4790 did not implement it or implemented it the wrong way.
4792 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Register default ciphers and stuff when using the -S option
4795 in the client. Affected file silc/silc.c. Same also when
4796 creating new key pair with -C option.
4798 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Fixed the silc_verify_public_key client operation function to
4801 save the public keys differently. The fingerprint is now
4802 used as filename and not the hostname. This way also the
4803 client keys are saved uniquely and not with hostnames. The
4804 affected file is silc/client_ops.c.
4806 * Trimmed the silc_hash_fingerprint function to remove extra
4807 whitespaces from the end of the fingerprint. The affected
4808 file is lib/silccrypt/silchash.c.
4812 * Added silc_cipher_register_default function to register all
4813 default ciphers. It can be used when configuration files
4814 does not exist and the application does not want any specific
4815 ciphers in any specific order.
4817 The SilcDList is now used as silc_cipher_list dynamically
4818 allocated cipher list. Removed the static list all together
4819 and now all ciphers must be allocated to the dynamic list.
4820 The silc_cipher_alloc routine was changed to check only the
4823 All silc_cipher_* routines that used to return int returns
4826 The affected files lib/silccrypt/silccrypt.[ch].
4828 * The same thing was done to silc_hash_* as for silc_cipher_*
4829 routines. Affected files lib/silccrypt/silchash.[ch].
4831 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4832 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4833 Added also silc_pkcs_[un]register[_default] functions.
4834 Removed the data_context from the PKCS API.
4836 * Added silc_hmac_register_default function to register default
4837 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4838 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4839 to unregister all hmacs at once.
4841 * Register the default ciphers, hash functions, PKCSs and HMACs
4842 if client's configuration file does not exist. The affected
4845 * The client did not load the hash functions from the SIM
4846 modules at all. Added support for this. Affected file is
4847 silc/clientconfig.c.
4849 * When decoding public key with silc_pkcs_public_key_decode, check
4850 the supported algorithm only if PKCS are registered. Affected
4851 file lib/silccrypt/silcpkcs.c. The same was done with the
4852 silc_pkcs_private_key_decode.
4854 * Fixed the SILC List routines to keep the list always in order.
4855 It used to change the list's order when traversing the list but
4856 not it preserves the order. Affected file lib/trq/silclist.h.
4858 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4860 * Added the client library to use the SilcSocketConnection's
4861 reference counter (by silc_socket_dup) to prevent the bug that
4862 the socket object may be freed underneath async operation.
4864 * The name resolv library checking fixes in the configure.in.pre.
4867 * Created new version of the protocol drafts for future
4868 development. The -03 drafts are the ones that will be changed
4869 in the trunk now and the -02 will remain as they are.
4871 * Send list of CUMODE notifys to the router when announcing
4872 the channel users to the router. Affected file silcd/server.c.
4873 If the router receiving channel founder CUMODE for a channel
4874 that already has channel founder it will send CUMODE notify
4875 to the sender to remove the channel founder rights from the
4876 announced client. Affected file silcd/packet_receive.c.
4878 * The CUMODE notify may now use Server ID as well as the entity
4879 who changes the mode. Updated protocool specs.
4881 * Updated INSTALL and README files.
4883 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * New web pages in the http://silc.pspt.fi. The pages was
4890 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Implemented the [DenyConnectin] config section in the server.
4893 Added silc_server_config_denied_conn to check whether incoming
4894 connection is denied. Affected file silcd/serverconfig.[ch].
4896 * Do not check the ports when checking the incoming configuration
4897 data if the port is 0, meaning any. Affected file is
4898 silcd/serverconfig.c.
4900 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Fixed buffer overflow in silc_string_compare in the file
4903 lib/silcutil/silcutil.c.
4905 * Fixed double free in silc_server_command_leave in the file
4908 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Fixed the version checking in the server. Affected file is
4913 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4915 * Fixed the configuration data fetching when accepting new
4916 connections in the server. Affected file silcd/server.c.
4918 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4920 * Added `sender_entry' argument to the function
4921 silc_server_packet_relay_to_channel so that we can check
4922 whether some destination actually belongs to the same route
4923 the sender belongs (ie, we must not resend the packet to the
4924 sender). Affected file silcd/packet_send.[ch].
4926 * Added `servername' field to the SilcClientEntry in the server
4927 to hold the name of the server where client is from. Affected
4928 file is silcd/idlist.h.
4930 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Moved the channel message encrypting in the router betwen
4933 router connections from silc_server_channel_message to the
4934 silc_server_packet_relay_to_channel since we want to check
4935 whether we have anybody channel before encrypting anything.
4936 Affected files silcd/packet_[receive/send].c.
4938 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Fixed the [AdminConnection] server config section to support
4941 multiple entries. Affected file silcd/serverconfig.c.
4943 * Added support into the server to check the validity of the
4944 incoming connection before executing any KE or authentication
4947 * The connection configuration is now saved to the KE and
4948 connection auth protocol contexts and not fetched anymore in
4949 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4951 * The local hosts listenning address and port is also resolved
4952 now when starting the server. We want to have the socket object
4953 to include the real address and port for the listener. Added
4954 new function silc_net_check_local_by_sock into the files
4955 lib/silcutil/silcnet.[ch].
4957 * Fixed a broadcast bug in server -> do not broadcast if we
4960 * Fixed a routing bug. Do not route broadcast packets ever.
4961 Broadcast packets must be processed always and not routed since
4962 they may be destined to some other host than yourself and thus
4963 would get routed without no good reason. Affected file is
4966 * Added function silc_server_config_is_primary_route to check
4967 whether primary router connection has been configured (a router
4968 configuration that we are initiating). If there is not, we
4969 will assume that there is only two routers in the SILC network
4970 and we will use the incoming router connection as our primary
4971 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4973 * Changed the order of the broadcasting. Broadcast _after_ the
4974 packet has been processed not before. Affected file is
4977 * Fixed a [ClientConnection] parsing bug. The port was never
4978 parsed correctly thus resulting to port 0. Affected file
4979 silcd/serverconfig.c.
4981 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4982 argument and did not set the broadcast packet flag. Affected
4983 file silcd/packet_send.c. Fixed same bug in the function
4984 silc_server_send_notify as well.
4986 * If we receive NEW_ID packet for our own ID in the server, ignore
4989 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Removed the nickname from the Private Message Payload.
4994 Updated the code and the protocol specs.
4996 * Updated protocol specs for submitting to the IETF.
4998 * Tweaked the Random Number Generator a bit. Affected file
4999 lib/silccrypt/silcrng.c. Exported a new function
5000 silc_rng_[global]_add_noise which can be used to add more
5003 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Do not parse packets with different timeout when protocol
5006 is active -> may cause problem with rekey. Affected file
5009 * When server receives signoff notify it must not create
5010 new channel key if the client is on any channels since the
5011 sender of the signoff notify will create it.
5013 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Added printing of error messages during SKE protocol from the
5016 failure packet sent by server during SKE. Affected file
5019 * Removed the client's failure_callback handling with timeout
5020 and handle it immediately when received.
5022 * The SKE library returned wrong type in SUCCESS and FAILURE
5023 packets. They must be 32 bit MSB not 16 bit MSB.
5025 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Ok, rewrote the logic of the re-key and now it seems to work.
5028 I tested it on high traffic with frequent re-keys without
5029 problems. Added hmac_receive (and renamed hmac to hmac_send)
5030 in SilcClientConnection in lib/silcclient/client.h and
5031 in SilcIDListData in silcd/idlist.h. Also, removed the
5032 SilcPacketParserContext's cipher and hmac fields as they are
5033 not needed anymore and actually caused some problems when
5034 the ciphers and hmac's changed underneath the packet parser.
5036 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * If re-key protocol is active then process the incoming packets
5039 synchronously since we must assure that icoming packets encrypted
5040 with the old key is processed before the new keys is set to
5041 use. This is true other packets than for REKEY packets.
5042 Affected file silcd/server.c. The same was done to client library
5043 as well, affected file lib/silcclient/client.c.
5045 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Fixed bug in client and server to accept the force send if
5048 the packet is send from silc_[server/client]_packet_process
5049 function. Otherwise the packets are never delivered, oops.
5051 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5053 * Disable force sending of packets when REKEY protocol is active.
5054 We must assure that no packet is sent directly when rekey is
5055 performed. All packets must be sent through packet queue.
5056 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5057 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5058 function is silc_[server/client]_packet_send_real to check
5061 * Replaced the SIM paths from example config files to
5062 /usr/local/modules. Also, make install creates now
5063 /usr/local/silc/logs directory to hold all the SILC server
5066 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * Made the configure.in.pre work on Solaris. Patch by salo.
5070 * Made all ciphers compatible with non-x86 machines. Defined
5071 CBC mode macros into lib/silccrypt/ciphers_def.h.
5073 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5075 * Fixed the make install.
5077 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * When MAC computation fails the silc_packet_decrypt returned 0
5080 even though it was supposed to return -1. Fixed this. The
5081 affected file is lib/silccore/silcpacket.c.
5083 * Do not replace the config files in /etc/silc (in make install)
5084 if they already exist. Affected file ./Makefile.am.
5086 * Do not send re-key packets immediately but through packet queue.
5087 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5089 * Changed silc_net_check_host_by_sock to return FALSE if the
5090 IP/DNS could not be resolved. Though, it returns the IP address
5091 now even if it could not resolve it (but returns also FALSE).
5092 Affected file lib/silcutil/silcnet.[ch].
5094 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Added silc_pkcs_decode_identifier to decode the public key's
5097 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5098 Added also silc_pkcs_free_identifier. Added also new context
5099 SilcPublicKeyIdentifier.
5101 * Added -S option to the silc client. It is used to dump the
5102 contents of the specified public key file.
5104 * Changed the PKCS api to return the public key length when
5105 setting the public key.
5107 * Fixed a fatal bug in the public and private key file loading.
5108 Affected file lib/silccrypt/silcpkcs.c.
5110 * Execute the packet parsing for client with zero (0) timeout
5111 if the protocol is active. Affected file silcd/server.c.
5113 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Made the key generation options to the silcd program. Added
5116 -C option, equivalent to client's option.
5118 * Added new [ServerKeys] config section to the server. It
5119 configures the server's public and private key.
5121 * Defined generic Public Key Payload into the protocol
5122 specification to send specific type of public keys and
5125 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5126 public key or certificate.
5128 * Implemented the GETKEY command to the server and to the
5129 client library and on user interface.
5131 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Made preliminary `make install' work.

5162 SilcClientConnection structure; not needed. Affected file is
5163 lib/silcclient/client.h.
5167 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * Do not ask whether user wants to use the negotiated private key
5170 for private messages, just use it. Affected file is
5171 silc/local_command.c.
5173 * Added `send_enc_key' and `enc_key_len' fields to the
5174 SilcIDListData structure since they are needed in the re-key

5194 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5195 int64 of at least the xintXX size. If void * is less that 4
5196 bytes uint32 * will be used. Defined bool as boolean.
5198 * Changed _ALL_ unsigned long and unsigned int to uint32,
5199 unsgined short to uint16 in the source tree.
5201 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5202 not handle clients that has entry->data.registered == FALSE.
5203 They are not in the network anymore. Affected file is
5206 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Implemented the sending of the SERVER_SIGNOFF notify in the

5224 if the deleting was successful. Affected file silcd/idlist.[ch].
5226 * Added support for public key authentication in the connection
5227 authentication protocol in the client library. Affected file
5228 lib/silcclient/protocol.c.
5230 * Changed the server's silc_idlist_get_clients_by_* interface
5231 to support already allocated array so that new entries may be

5233 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5234 and command replies.
5236 * All command reply functions in the server now calls the
5237 pending command callback even if error occured. This way the
5238 error will be delivered to the client as well. Affected files
5239 silcd/command.c and silcd/command_reply.c.
5241 * Fixed INFO command to return local server's info if no server
5242 was provided. Affected file lib/silcclient/command.c.
5244 * Removed RESTART command for good. Updated the code and the
5247 * Rewrote parts of the task system. It is a bit simpler now.
5248 Removed unsued task priorities. The affected files are
5249 lib/silcutil/silctask.[ch].
5251 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5253 * Moved the USERS printing from the library to the application.
5254 Affected files lib/silcclient/command.c and silc/client_ops.c.
5256 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Added channel key re-key support. The re-key is perfomed
5261 only by the router and is done once in an hour. Added `rekey'
5262 field to the SilcChannelEntry in the server. Affected files
5263 silcd/server.c and silcd/idlist.h.
5265 * Added silc_task_unregister_by_context into the file
5266 lib/silcutil/silctask.[ch].
5268 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Added SILC_UMODE_GONE mode to indicate when the client is not
5271 present in the SILC network. Added also support to the local
5272 command AWAY that will set this mode. Added support of showing
5273 "xxx is gone" in WHOIS command. The USERS command shows the
5274 gone status as well.
5276 * Fixed setting server and router operator privileges in the
5277 server's UMODE command. Affected file silcd/command.c.
5279 * Merged the SKE KE1 and KE2 payloads into one payload. The
5280 new KE payload is equivalent to the old KE2 payload.
5282 Cleaned up the SKE Start Payload parsing. It now uses the
5283 simple buffer unformatting to do the parsing. A lot faster
5286 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5287 to the SKE that is used to indicate whether both of the SKE
5288 parties should perform authentication. By default only the
5289 responder performs authentication. By setting this flag also
5290 the initiator must do authentication. By default it is unset
5291 since in normal SKE case, client to server connection, only
5292 the responder should do authentication. When doing SKE between
5293 two clients both should perform authentication. Updated the
5294 code and the protocol specs.
5296 * A little fix to IDENTIFY command in the server. Search the
5297 client first by hash not nickname. Affected file is
5300 * Fixed the silc_client_close_connection to support closing
5301 the client to client connections wihtout deleting too much
5302 data. Affected file lib/silcclient/client.c.
5304 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5305 are received if protocol used to be active but is not anymore
5306 the application would crash due to NULL pointer dereference.
5307 Affected files silcd/server.c and lib/silcclient/client.c.
5309 * Added `hash' field to the SilcClientConnection to include
5310 the hash function negotiated in the SKE protocol.
5312 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5313 to set the channel founder authentication data. A client can
5314 claim the founder rights later by providing the authentication
5315 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5316 This way the channel founder can regain the channel founder
5317 privileges even it is left the channel. This works only on
5318 local server and the client must be connected to the same
5319 server to be able to regain the founder rights. Updated the
5320 protocol specs accordingly.
5322 Added support to the CMODE command in the client to set the
5323 founder auth data. Read the README to see how to set it.
5325 Added support to the CUMODE command to claim the founder
5326 rights. Read the README to see how to do it.
5328 Added support for the founder authentication to the Channel
5329 Entry in the server. Affected file silcd/idlist.h.
5331 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5332 server's CMODE command. Affected file silcd/command.c.
5334 * Added the following new functions into lib/silccore/silcauth.[ch]:
5335 silc_auth_get_method and silc_auth_get_data.
5337 * The server now saves the remote hosts public key to the
5338 SilcIDListData pointer. Affected file silcd/protocol.c.
5340 * The normal server now does not remove the channel entry from
5341 the cache if the founder authentication data is set. It used
5342 to remove it if the founder was the last one on the channel on
5343 the server and left the channel. The auth data is saved and
5344 if the channel is re-joined later the old entry is used with
5345 the old auth data. Affected files silcd/command_reply.c and
5348 * Removed the `pkcs' field from the SilcIDListData structure
5349 in the server; it is not used. Affected file silcd/idlist.h.
5351 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5353 * Fixed packet processing on slow links. Partial packets were
5354 never re-processed because the incoming data buffer was cleared
5355 by the application. Application must not directly clear the
5356 sock->inbuf, the packet processing routines handle it. Fixed
5357 this in client library and in server.
5359 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Fixed the WHOIS and IDENTIFY send reply function to really
5362 check whether to send list or just one entry. Affected file
5365 * Cleaned up the LEAVE command's channel key distribution. The
5366 affected file silcd/command.c.
5368 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5369 can enforce the channel mode as well. In that case the ID
5370 includes the ID of the server. The code now enforces the
5371 mode change if the router have different mode than the server.
5373 * The notify client operation with CMODE_CHANGE notify can now
5374 return NULL client_entry pointer if the CMODE was not changed
5375 by client. Application must check for this.
5377 * Added <Server ID> argument to INFO command to support server
5378 info fetching by Server ID.
5380 * Added silc_server_announce_get_channel_users to get assembled
5381 packets of channel users of the specified channel. Affected
5382 file silcd/server.[ch].
5384 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5385 was freed underneath the ID Cache.
5387 * Re-announce clients when the server received CHANNEL_CHANGE
5388 notify from the router. Affected file silcd/packet_send.c.
5390 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5392 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5393 crashed since it did not handle the fact that there is no cipher
5394 called "3" and didn't check the error condition. Now fixed.
5396 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5397 flag. It can be used to send message requests.
5399 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Implemented the RESTART command in the client.
5403 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5404 notice type messages. Added notice printing to the user
5407 * The channel keys are not re-generated if the channel's mode
5408 is PRIVKEY, ie private key on the channel exists. Affected
5409 files silcd/server.c and silcd/command.c.
5411 * Fixed a little bug in channel message delivery when channel
5412 private keys are set in the server. Affected file is
5413 silcd/packet_send.c.
5415 * Changed the setting on channel->on_channel = TRUE from the
5416 silc_client_save_channel_key to the JOIN command reply. The
5417 key payload is not received if the private channel key is set.
5418 Affected file lib/silcclient/command_reply.c and the
5419 lib/silcclient/client_channel.c.
5421 * When the CMODE_CHANGE notify is sent and the channel private
5422 key mode is removed the channel key must be re-generated in
5423 other cells as well. Added this support for the router in the
5424 silcd/packet_receive.c.
5426 * Added new local command NOTICE to send notice message on
5427 channel. Affected file silc/local_command.[ch].
5429 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Added new local command ME to the client. It is used to send
5432 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5433 some action. Affected file silc/local_command.[ch].
5435 * Changed channel_message and private_message client operations
5436 to deliver the message flags to the application. Added also
5437 the `flags' arguments to the silc_client_send_channel_message
5438 and silc_client_send_private_message functions. Affected file
5441 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Redefined the Private Message Payload to support private message
5444 keys and to support the new private message flags. Updated
5445 the protocol specs. Flags makes it possible to have for example
5446 CTCP style messages.
5448 * Added new type SilcPrivateMessagePayload and defined an API
5449 for it in the lib/silcclient/silcprivate.[ch].
5451 * Tested private message private keys successfully. Tested the
5452 private message key set, unset and list commands with the new
5455 * Redefined the Channel Message Payload to include the channel
5456 message flags (equal with private message flags) to support
5457 for example CTCP style messages.
5459 * Defined some of the message (for channel and private message)
5460 flags. Updated the protocol specs and added the flags to the
5461 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5463 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5465 * Added SilcKeyAgreementStatus type to the key agreement routines
5466 to indicate the current status and error if one occured.
5467 The status types are defined in the lib/silcclient/silcapi.h.
5469 * Added new local command KEY that is used to set and unset private
5470 keys for channels, set and unset private keys for private messages
5471 with remote clients and to send key agreement requests and
5472 negotiate the key agreement protocol with remote client. The
5473 key agreement is supported only to negotiate private message keys,
5474 it currently cannot be used to negotiate private keys for channels,
5475 as it is not convenient for that purpose.
5477 * Fixed a minor pending callback setting bug in the function
5478 silc_client_get_client_by_id_resolve, now the function works.
5479 Affected file lib/silcclient/idlist.c.
5481 * Added function silc_net_get_local_port to get local bound
5482 port by socket. Added to lib/silcutil/silcnet.[ch].
5484 * Added `sockets' and `sockets_count' fields to the SilcClient
5485 object. They hold the sockets of the listenning sockets in
5486 the client. Listenning sockets may be for example the key
5487 agreement server. Affected file lib/silcclient/client.[ch].
5488 Added functions the silc_client_add_socket and the
5489 silc_client_del_socket. They are exported to the application
5492 * Added ~./silc/clientkeys to support other client's public keys.
5494 * Renamed verify_server_key client operation to verify_public_key
5495 and added one argument to indicate the type of the connection
5496 (server, client etc.).
5498 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Added silc_server_connection_auth_request to handle the
5501 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5502 silcd/packet_receive.[ch].
5504 * Added silc_server_send_connection_auth_request into the
5505 silcd/packet_send.c to send the connection auth request packet.
5507 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5510 * Fixed the public key authentication in responder side in the
5511 server. The `auth_data' pointer includes the SilcPublicKey
5512 not the path to the public key. Affected file silcd/protocol.c.
5514 * Implemented the public key authentication in the initiator side
5515 in the server. Affected file silcd/protocol.c.
5517 * Removed the [RedirectClient] config section from the server
5518 configuration. Is not needed and I don't want to implement it.
5520 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5522 * Cleaned up the CMODE command in the server. It now works
5523 correctly and supports all the modes defined in the protocol.
5524 Affected file is silcd/command.c.
5526 * Added `hmac_name' field to the SilcChannelEntry in the server
5527 to hold the default HMAC of the channel. It can be set when
5528 creating the channel (with JOIN command). Affected files
5531 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5532 type to indicate the change of the current cipher and hmac
5533 on the channel. Client can safely ignore the <cipher> argument
5534 (if it chooses to do so) since the CHANNEL_KEY packet will
5535 force the channel key change anyway. The <hmac> argument is
5536 important since the client is responsible of setting the new
5537 HMAC and the hmac key into use.
5539 * Fixed the CMODE command in the client library as well.
5541 * Tested CMODE command in router environment successfully.
5543 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Show the version of the remote client (or server) when connecting
5546 to the server. It is logged to the log file. Affected file
5547 is silcd/protocol.c.
5549 * Fixed the KILLED notify handling in the client library. The
5550 client must be removed from all channels when receiving the
5553 Also, do not remove the client entry when giving the KILL
5554 command but when the KILLED notify is received.
5556 * Removed silc_idlist_find_client_by_nickname from the server.
5557 Not needed anymore. Affected files silcd/idlist.[ch].
5559 * Implemented the CHANNEL_CHANGE notify type handling to the
5560 server. Affected file silcd/server.c.
5564 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Added silc_server_send_notify_invite to send the INVITE
5567 notify between routers.
5569 * Implemented the INVITE command correctly to the server.
5571 * Implemented the INVITE notify type handling in the server.
5573 * Implemented the INVITE command to the client library and on the
5576 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5578 * Added function silc_server_get_client_resolve to find the
5579 client entry by ID from all ID lists and then resolve it
5580 (using WHOIS) if it cannot be found. Affected file is
5583 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Implemented the BAN command to the client library.
5587 * The JOIN command in the server now checks the invite list
5590 * Changed the silc_command_reply_payload_encode_va and the
5591 silc_command_payload_encode_va to support that if argument is
5592 NULL it ignores and checks the next argument. Affected file
5593 lib/silccore/silccommand.c.
5595 * Added silc_server_send_notify_ban to send the BAN notify
5596 type between routers.
5598 * Chaned the silc_notify_payload_encode to support that if
5599 argument is NULL it ignores and checks the next argument.
5600 Affected file lib/silccore/silcnotify.c.
5602 * Tested ban lists in router environment successfully.
5604 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Implemented BAN command to the server, in silcd/command.[ch].
5608 * Removed the BAN and INVITE_LIST modes from the CMODE command
5611 * Added function silc_string_match to regex match two strings.
5612 Affected files lib/silcutil/silcutil.[ch].
5614 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Redefined parts of the SilcChannelEntry in the server to support
5617 the new ban and invite lists.
5619 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Redefined the INVITE command. The same command can be used to
5622 invite individuals to the channel but also to manage the invite
5623 list of the channel (to add to and remove from the invite list).
5624 Updated the protocol specs.
5626 * Added new command SILC_COMMAND_BAN that can be used to manage
5627 the ban list of the channel. Updated the protocol specs.
5629 * Removed the channel modes: the SILC_CMODE_BAN and the
5630 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5631 in the CMODE command. The equivalent features are now available
5632 using INVITE and BAN commands. Updated the protocol specs.
5634 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5635 in the network about change in the current ban list. The notify
5636 type is not used by the client.
5638 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5639 support the invite lists.
5641 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Added new function silc_string_regexify that converts string
5644 including wildcard characters into regex string that can
5645 be used by the GNU regex library. Added into the file
5646 lib/silcutil/silcutil.[ch].
5648 Added silc_string_regex_combine to combine to regex strings
5649 into one so that they can be used as one regex string by
5650 the GNU regex library. Added into the file
5651 lib/silcutil/silcutil.[ch].
5653 Added silc_string_regex_match to match two strings. It returns
5654 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5656 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Imported GNU regex to the soruce tree into lib/contrib.
5659 Fixed some compiler warning from the regex.c.
5661 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5663 * Fixed MOTD command in the server to work in router environment.
5665 * Fixed the MOTD command in the client library to support
5666 the server argument in the command.
5668 * Added `nickname_len' argument to the silc_idlist_add_client
5669 in the server, as the `nickname' argument may be binary data
5672 * Added silc_idlist_get_channels to return all channels from
5675 * Implemented LIST command to the server. Affected file is
5678 * Implemented the LIST command to the client library and on the
5681 * Added [<user count>] argument to the LIST command reply.
5682 With private channels the user count is not shown.
5684 * Updated TODO and README.
5686 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5688 * The client entry's data.registered must be TRUE even with
5689 global client entry on global client list. The data.registered
5690 is used to check whether the client is anymore in the network,
5691 for example with WHOWAS command so it must be valid.
5693 * Fixed the WHOWAS command in the server. It now actually works
5694 in router environment. Added function into silcd/command_reply.c
5695 silc_server_command_reply_whowas_save.
5697 * Added silc_idlist_purge function to the silcd/idlist.c
5698 to periodically purge the ID Cache.
5700 * Fixed INFO command in the server. It works now in router
5701 environment. Added <server name> argument to the INFO command
5702 reply. Updated the protocol specs.
5704 * Fixed minor bug in silc_idcache_purge to not purge if the
5705 expire value is zero.
5707 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5708 they were buggy because of the WHOWAS information.
5710 * Fixed local command MSG to handle the async resolving of
5711 the remote client properly. It used to fail the first MSG.
5712 Affected file silc/local_command.c.
5714 * Added `data_len' field to SilcIDCache context.
5716 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Update TODO. Todo in commands in the server.
5720 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5723 used by routers as broadcast packet to inform other routers
5724 about the changed user mode.
5726 Implemented the notify handling in the server. Affected file is
5727 silcd/packet_receive.c. Added the function
5728 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5730 * Added new generic Channel Payload and deprecated the New Channel
5731 Payload. The New Channel Payload is now the generic Channel
5734 * Added new argument `mode' to the silc_server_send_new_channel
5735 as it is required in the Channel Payload now.
5737 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5738 and created a new and real SilChannelPayload to represent the
5739 new generic Channel Payload. Implemented the encode/decode
5740 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5742 * Added silc_server_get_client_channel_list to return the list
5743 of channels the client has joined for WHOIS command reply.
5744 Affected file silcd/server.[ch].
5746 * Implemented the channel list sending in the WHOIS command reply
5747 in server and in the client.
5749 Implemented the channel list displaying on the user interface
5750 as well. Affected file silc/client_ops.c.
5752 * Added silc_channel_payload_parse_list to parse list of Channel
5753 Payloads. It returns SilcDList list of SilcChannelPayloads.
5754 Client for example can use this function to parse the list of
5755 channels it receives in the WHOIS command reply. The caller
5756 must free the list by calling silc_channel_payload_list_free.
5757 Affected files lib/silccore/silcchannel.[ch].
5759 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Added one new argument <user mode> to the WHOIS command reply
5762 to return the mode of the user in SILC. Updated the protocol
5765 Implemented it to the server and client.
5767 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5769 * Fixed the mode printing on the user interface on joining.
5770 Affected file silc/client_ops.c.
5772 * Implemented the UMODE command and user modes in general to the
5773 client library and to the user interface.
5775 * Implemented the UMODE command to the server.
5777 * The server now sends UNKNOWN_COMMAND error status if client sends
5778 unknown command. Affected file silcd/command.c.
5780 * All server commands now handle the command identifier the right
5781 way when sending the command reply to the client. The client can
5782 use to identify the command replies with the identifier.
5784 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * Added silc_server_get_client_route to resolve the route to
5787 the client indicated by the client ID. Affected file is
5790 * Added silc_server_relay_packet as general function to relay
5791 packet to arbitrary destination. This deprecates functions
5792 like _send_private_message_key, _relay_notify etc. Affected
5793 file is silcd/packet_send.[ch].
5795 Removed silc_server_send_key_agreement,
5796 silc_server_send_private_message_key and
5797 silc_server_packet_relay_notify functions from the file
5798 silcd/packet_send.[ch].
5802 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5803 server. Affected file silcd/packet_receive.[ch].
5805 * Implemented the KILL command to the client. Implemented the
5806 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5807 Affected files lib/silcclient/command[_reply].c and
5808 lib/silcclient/client_notify.c. Implemented the KILL notify
5809 printing in the user inteface.
5811 * Fixed a lot silc_parse_nick memory leaks from the client
5812 library in the file lib/silcclient/command.c.
5814 * Changed the silc_server_send_notify_on_channels's `sender'
5815 argument from SilcSocketConnection to SilcClientEntry to
5816 check the sender as entry and not as connection object and not
5817 to send to the client provided as argument. The affected file
5818 is silcd/packet_send.[ch].
5820 * The notify packets that are destined directly to the client used
5821 to not to be processed by the server. Now changed that and the
5822 server processes all notify packets. After relaying the packet
5823 to the client the notify packet is processed in the server.
5825 * The silc_server_free_client_data now checks whether there is
5826 pending outgoing traffic for the client and purges the data to
5827 the network before removing the client entry.
5829 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5831 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5832 an client is killed from the SILC Network. Updated the protocol
5835 Added new function silc_server_send_notify_killed to the
5836 silcd/packet_send.[ch].
5838 * Added function silc_server_packet_relay_notify to relay notify
5839 packets that are destined directly to a client. In this case
5840 the server does not process the notify packets but merely relays
5841 it to the client. Affected file silcd/packet_send.[ch].
5843 Added also silc_server_packet_process_relay_notify to check
5844 whereto relay the notify. Affected file is
5845 silcd/packet_receive.[ch].
5847 * Implemented the KILL command to the server.
5851 * Added the backup schema desgined last fall to the protocol
5852 specs for everyone to see. The specification is in the
5853 *-spec-xx.txt draft and the packet type definitions for the
5854 backup routers is in *-pp-xx.txt draft. Thusly, added also
5855 new packet type SILC_PACKET_CELL_ROUTERS.
5857 * A big security problem in the implementation discovered. The
5858 signoff of an client did not cause new channel key generation
5859 which it of course should've done. The channel keys must be
5860 always re-generated when client leaves (or signoffs) the channel.
5861 The silc_server_remove_from_channels funtion now handles
5862 the channel key re-generation.
5864 * Added `sender' argument to the silc_server_send_notify_on_channels
5865 to not to send the client provided as argument. Affected file
5866 silcd/packet_send.[ch].
5868 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Implemented OPER and SILCOPER commands into the server and
5873 * Added silc_auth_verify and silc_auth_verify_data to verify
5874 the authentication directly from the authentication payload.
5875 It supports verifying both passphrase and public key based
5876 authentication. Affected file lib/silccore/silcauth.[ch].
5878 * Added `hash' field to the SilcIDListData structure. It is the
5879 hash negotiated in the SKE protocol. Affected file is
5882 * Slight redesigning of the SilcAuthPayload handling routines.
5883 Do not send SilcPKCS but SilcPublicKey as argument.
5885 * Implemented the public key authentication support to the
5886 serverconfig. The public key is loaded from the provided path
5887 and saved as authentication data to void * pointer. Thus,
5888 changed the unsigned char *auth_data to void *auth_data;
5890 * Fixed SHUTDOWN command to send the reply before the server
5891 is shutdown. :) Affected file silcd/command.c.
5893 * Fixed fatal bug in CONNECT command. The hostname was invalid
5894 memory and server crashed. Affected file silcd/command.c.
5896 * Fixed fatal bug in CLOSE command. The server_entry became
5897 invalid but was referenced later in the command. Affected file
5900 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Fixed fatal bug in failure packet handling. Server ignored
5903 the failure and thus crashed when it came.
5907 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5910 that the command may be executed only once in (about) 2 seconds.
5911 The old SILC_CF_LAG flag is same but allows command bursts up
5912 to five before limiting.
5914 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5915 server code. Various commands now includes the CF_LAG_STRICT
5916 flag to disallow any kind of miss-use of the command.
5918 * Fixed the silc_buffer_unformat to not to allocate any data
5919 if the length of the data is zero. It used to allocate the
5920 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5922 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Changed the format of AdminConnection configuration section
5925 in the server. Added username of the admin to the format.
5926 Affected files silcd/serverconfig.[ch].
5928 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5929 to return admin configuration data by host, username and/or
5932 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5934 * Implemented WHOWAS command to the server. Added the functions:
5936 silc_server_command_whowas_parse,
5937 silc_server_command_whowas_send_reply,
5938 silc_server_command_whowas_from_client and
5939 silc_server_command_whowas_from_server
5941 * Added <Client ID> argument to the WHOWAS command reply. Updated
5942 the protocol specs accordingly.
5944 * Implemented WHOWAS command and command_reply to the client
5947 Implemented the WHOWAS printing on the user interface.
5949 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5951 * Added new argument to the WHOWAS command reply, the real name.
5952 It is an optional argument. Updated the protocol specs.
5954 * Added SilcIDCacheDestructor callback that is registered when
5955 the SilcIDCache is allocated. The callback is called when
5956 an cache entry in the ID Cache expires, or is purged from the
5957 cache. Added into lib/silccore/idcache.[ch].
5959 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5960 to destruct the client entries when the cache entry expires.
5961 Other ID Cache's in server and in the client library ignores
5964 * If the ID Cache entry's `expire' field is zero then the entry
5965 never expires. Added boolean `expire' argument to the
5966 silc_idcache_add function in the lib/silccore/idcache.[ch].
5967 If it is TRUE the default expiry value is used.
5969 * Added silc_server_free_client_data_timeout that is registered
5970 when client disconnects. By default for 5 minutes we preserve
5971 the client entry for history - for WHOWAS command.
5973 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5975 * Added support to the server to enforce that commands are not
5976 executed more than once in 2 seconds. If server receives
5977 commands from client more frequently, timeout is registered
5978 to process the commands. Affected file silcd/command.c.
5979 Added new function silc_server_command_process_timeout.
5981 * Changed NICK_NOTIFY handling in client library to check that
5982 if the client's nickname was changed, so there is no need to
5983 resolve anything from the server.
5985 * Removed error printing from the WHOIS and IDENTIFY commands.
5986 If error occurs then it is ignored silently in the client library.
5987 The application, however, may map the received error to
5988 human readable error string. The application currently maps
5989 the NO_SUCH_NICKNAME error to string.
5991 * Made the command status message public to the application. Moved
5992 them from lib/silcclient/command_reply.c to
5993 lib/silcclient/command_reply.h. The application can map the
5994 received command status to the string with the
5995 silc_client_command_status_message function.
5997 * Added check to the server to check that client's ID is same
5998 as the Source ID in the packet the client sent. They must
6001 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6003 * Added dist-bzip hook to the Makefile.am to make bzip2
6004 compressed distributions.
6006 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Server now enforces the maximum length for the nickname and
6009 the channel as protocol specification dictates. 128 bytes for
6010 nickname and 256 bytes for channel name.
6012 * Moved the WHOIS printing to the application. The client libary
6013 does not print out the WHOIS information anymore, the application
6014 must do it. Renamed silc_client_command_reply_whois_print to
6015 the silc_client_command_reply_whois_save.
6017 The client's idle time is also sent to the application now, and
6018 the idle is shown on screen.
6020 * Added silc_client_command_reply_identify_save to save the
6021 received IDENTIFY entries.
6023 * Do not check for channel private keys in message sending and
6024 reception if the channel does not have the PRIVKEY mode set.
6025 Affected file lib/silclient/client_channel.c.
6027 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6030 just surfaced after chaning the JOIN procedure.
6032 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Added silc_client_get_clients_by_list to get client entries
6035 from Client ID list, that is returned for example by JOIN
6036 and USERS command replies. The application should use this
6037 function for example when JOIN command reply is received to
6038 resolve the clients already on the channel (library does not
6039 do that anymore as USERS command reply is not used in the JOIN
6040 procedure anymore). Affected files lib/silcclient/silcapi.h and
6041 lib/silcclient/idlist.c.
6043 * JOIN command reply and USERS command reply returns now SilcBuffer
6044 pointers instead of unsigned char pointers when returning
6045 the client list and mode list.
6047 * Added <Client ID> argument to the JOIN command reply, mainly
6048 for the server to identify for which client the command was
6049 originally sent. Updated protocol specs accordingly.
6051 * Added SilcDlist private_key pointer to the SilcChannelEntry
6052 in the client to support the channel private keys. Affected
6053 file is lib/silcclient/idlist.h.
6055 * Added SilcChannelPrivateKey argument to the function
6056 silc_client_send_channel_message so that application can choose
6057 to use specific private ke if it wants to. If it is not provided,
6058 the normal channel key is used, unless private keys are set.
6059 In this case the first (key that was added first) is used
6060 as the encryption key.
6062 * Implemented the support for channel private key handling.
6063 Implemented the following functions:
6065 silc_client_add_channel_private_key,
6066 silc_client_del_channel_private_keys,
6067 silc_client_del_channel_private_key,
6068 silc_client_list_channel_private_keys and
6069 silc_client_free_channel_private_keys
6071 Affected file lib/silcclient/client_channel.c.
6073 * Added the support for the private keys in the channel message
6074 sending and encryption and in the message reception and
6075 decryption. Affected funtions are
6076 silc_client_send_channel_message and silc_client_channel_message.
6078 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Added SKE's key verify callback to the client library's
6081 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6083 * Removed the statement that server (or router) must send USERS
6084 command reply when joining to the channel so that the client
6085 knows who are on the channel. Instead, the client list and
6086 client's mode list is now sent in the JOIN command reply to the
6087 client who joined channel. This is better solution.
6089 * Added function silc_server_get_users_on_channel and function
6090 silc_server_save_users_on_channel to the silcd/server.[ch].
6092 * Removed function silc_server_command_send_users from the
6095 * Do not show topic on the client library anymore. The topic is
6096 sent in the command reply notify to the application and the
6097 application must show the topic now.
6099 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Added client searching by nickname hash into the IDENTIFY and
6102 WHOIS commands in the server as they were clearly missing from
6103 them. Affected file is silcd/command.c.
6105 * Fixed a bug in private message receiving in the client library.
6106 The remote ID was freed and it wasn't supposed, now it is
6109 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6111 * Minor fix to the channel payload; allocate the data area, as it
6112 needs to be of specific length.
6114 * If the key agreement port is zero then the operating
6115 system will define the bound port. Affected files are
6116 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6118 * Added new function silc_channel_payload_decrypt into the file
6119 lib/silccore/silcchannel.[ch].
6121 * Moved the channel message etc, check from silc_packet_decrypt
6122 to applications. The library calls now a generic
6123 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6124 when the packet is either normal or special. This was done to
6125 allow more wide range of checking that was not allowed when
6126 the code was in library. Now applications can do virtually any
6127 checks to the packet and return to the library the decision how
6128 the packet should be processed. Affected files are
6129 lib/silccore/silcpacket.[ch].
6131 Added silc_server_packet_decrypt_check to the server and
6132 silc_client_packet_decrypt_check to the client library.
6134 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6135 to send with specified source and destination information.
6137 * Channel message delivery between routers was broken after the
6138 channel key distribution was fixed earlier. The channel key
6139 was used be to distributed to other routers as well which is not
6140 allowed by the protocol. Now this is fixed and channel keys
6141 really are cell specific and the channel message delivery between
6142 routers comply with the protocol specification.
6144 * Fixed various commands in server to check also the global list
6145 for the channel entry and not just the local list. The affected
6146 file silcd/command.c.
6148 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6150 * Added assert()s to buffer formatting and unformatting routines
6151 to assert (if --enable-debug) when error occurs. Affected
6152 file: lib/silcutil/silcbuffmt.c.
6154 * Changed to auto-reconnect to check whether the remote host is
6155 router and register the re-connect timeout if it is. It used
6156 to check that whether we are normal server, but router must do
6157 auto-reconnect with another router as well. Affected file
6160 * Removed the [<key len>] option from CMODE command as the cipher
6161 name decides the key length, nowadays. See the defined ciphers
6162 from the protocol specification.
6164 * Added [<hmac>] option to the CMODE command to define the HMAC
6165 for the channel. Added SILC_CMODE_HMAC channel mode.
6167 * Added [<hmac>] option for the JOIN command so that user can
6168 select which HMAC is used to compute the MACs of the channel
6171 * Added Hmac field to the Channel Message Payload. The integrity
6172 of plaintext channel messages are now protected by computing
6173 MAC of the message and attaching the MAC to the payload. The
6174 MAC is encrypted. Now, it is clear that this causes some
6175 overhead to the size of the packet but rationale for this is that
6176 now the receiver can verify whether the channel message decrypted
6177 correctly and also when private keys are set for the channel the
6178 receiver can decrypt the packet with several keys and check from
6179 the MAC which key decrypted the message correctly.
6181 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6182 lib/silccrypt/silccipher.[ch].
6184 * Added silc_hash_len to return the digest length into the
6185 lib/silcrypt/silchash.[ch].
6187 * Rewrote parts of Silc Channel Payload interface in the
6188 lib/silccore/silcchannel.[ch]. The encode function now also
6189 encrypts the packet and parse function decrypts it.
6191 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6193 * Fixed a minor formatting bug in the SKE's key material processing.
6194 It actually might have processed the keys wrong way resulting
6197 * Redefined the mandatory HMAC algorithms and added new algorithms.
6198 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6199 and hmac-md5 truncated to 96 bits. The mandatory is now
6200 hmac-sha1-96. Rest are optional (including the one that used
6201 to be mandatory). Rationale for this is that the truncated HMAC
6202 length is sufficient from security point of view and can actually
6203 make the attack against the HMAC harder. Also, the truncated
6204 HMAC causes less overhead to the packets. See the RFC2104 for
6207 * Added new [hmac] configuration section. The SKE used to use
6208 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6209 is of course wrong. The official names that must be proposed in
6210 the SKE are the ones defined in the protocol specification
6211 (hmac-sha1-96 for example). The user can configure any hmac
6212 using any hash function configured in the [hash] section. At
6213 least, the mandatory must be configured.
6215 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6217 * Added HMAC list to the SKE proposal list. It has now both
6218 hash algorithm list and HMAC list. This makes the protocol
6219 incompatible with previous versions. The SKE now seems to work
6220 the way it is supposed to work, for the first time actually.
6222 * Defined plain Hash algorithms to the protocol specification.
6225 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Implemented support for key agreement packets into the server.
6228 Added functions silc_server_key_agreement and
6229 silc_server_send_key_agreement. Other than these functions,
6230 server has nothing to do with this packet.
6232 * Added support for private message key packets into the server.
6233 Added functions silc_server_private_message_key and
6234 silc_server_send_private_message_key.
6238 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6239 called in the protocol's final callback instead in the END
6240 protocol state. This makes a little more sense and in the same
6241 time in client we can use the same protocol routines for normal
6242 key exchange and to key agreement packet handling as well.
6244 * Added to both client's and server's KE protocol context the
6245 SilcSKEKeyMaterial pointer to save the key material. We will
6246 bring the key material to the protocol's final callback by doing
6247 this. The final callback must free the key material.
6249 * Added SKE's packet_send callback into client's KE protocol
6250 context so that the caller can choose what packet sending function
6251 is used. This way we can use different packet sending when
6252 doing normal SKE when doing key agreement packet handling (in
6253 the key agreement packet handling we do not want to encrypt
6256 * Implemented the responder side of the key agreement routines
6257 in the client. The client can now bind to specified port and
6258 accept incoming key negotiation. The key material is passed
6259 to the application after the protocol is over.
6261 * Implemented the processing of incoming Key Agreement packet
6262 in the client. Added function silc_client_key_agreement to
6265 * Implemented the intiator side of the key agreement routines
6266 in the client. The client can now initiate key agreement with
6267 another remote client. The key material is passed to the
6268 application after the protocol is over.
6270 * Created client_keyagr.c to include all the key agreement
6273 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6274 SILC_TASK_CALLBACK except that it is not static.
6276 * Created client_notify.c and moved the Notify packet handling
6277 from the client.[ch] into that file.
6279 * Created client_prvmsg.c and moved all private message and
6280 private message key routines from the client.[ch] into that file.
6282 * Create client_channel.c and moved all channel message and
6283 channel private key routines from the client.[ch] into that file.
6285 * Changed silc_client_get_client_by_id_resolve to resolve with
6286 WHOIS command instead of IDENTIFY command, in the file
6287 lib/silclient/idlist.c.
6289 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6291 * Implemented the SKE's responder side to the Client library.
6293 * When FAILURE is received to the protocol do not trust it
6294 blindly. Register a timeout to wait whether the remote closes
6295 the connection as it should do it, only after that process the
6296 actual failure. This was changed to both client and server.
6298 * Added client_internal.h to include some of the structures
6299 there instead of client.h in lib/silcclient/.
6301 * Added function silc_task_unregister_by_callback to unregister
6302 timeouts by the callback function.
6304 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6306 * Some "Incomplete WHOIS info" errors has been appearing on the
6307 log files. Took away the entry->userinfo check from WHOIS
6308 reply sending. The entry->userinfo is now " " if client did not
6309 provide one. I thought this was fixed earlier but something
6310 is wrong still. Let's see if the error still appears.
6312 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Fixed a minor bug in the login when the channel key is
6315 re-generated in the server. It used to generate the key in
6316 wrong order and thus caused problems in the channel traffic.
6318 * Fixed a minor bug in channel key distsribution after
6319 KICK command. The key was not sent to the router even though
6322 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6324 * Added silc_ske_process_key_material_data as generic routine
6325 to process any key material as the SILC protocol dictates. The
6326 function is used by the actual SKE library but can be used by
6327 applications as well. This relates to the private message keys
6328 and the channel private keys since they must be processed the
6329 same way the normal SILC session keys. The protocol dictates
6330 this. Affected files: lib/silcske/silcske.[ch].
6332 Added also silc_ske_free_key_material to free the
6333 SilcSKEKeyMaterial structure.
6335 * Defined silc_cipher_set_key function to set the key for
6336 cipher without using the object's method function. The affected
6337 files: lib/silccrypt/silccipher.[ch].
6339 * Implemented silc silc_client_add_private_message_key,
6340 silc_client_add_private_message_key_ske,
6341 silc_client_del_private_message_key,
6342 silc_client_list_private_message_keys and
6343 silc_client_free_private_message_keys functions in the
6346 Added functions silc_client_send_private_message_key to send
6347 the Private Message Key payload and silc_client_private_message_key
6348 to handle incoming Private Message Key payload.
6350 * Added Cipher field to the Private Message Key payload to set
6351 the cipher to be used. If ignored, the default cipher defined
6352 in the SILC protocol (aes-256-cbc) is used.
6354 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6356 * Removed lib/silcclient/ops.h file.
6358 Redefined parts of the SILC Client Library API. Created new
6359 file silcapi.h that deprecates the ops.h file and defines the
6360 published Client Library API. Defined also private message key
6361 API and channel private key API into the file.
6363 This is the file that the application must include from the
6364 SILC Client Library. Other files need not be included by
6365 the application anymore.
6367 * Added new key_agreement client operation callback and also
6368 defined the Key Agreement library API for the application.
6370 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6373 is used by clients to request key negotiation between another
6374 client in the SILC network. If the negotiation is started it
6375 is performed using the SKE protocol. The result of the
6376 negotiation, the secret key material, can be used for example
6377 as private message key.
6379 Implemented the Key Agreement payload into the files
6380 lib/silccore/silauth.[ch].
6382 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6384 * Redefined ciphers for the SILC protocol. Added some new ciphers
6385 and defined the key lengths for the algorithms. Changed the
6386 code accordingly. The default key length is now 256 bits.
6388 * Fixed SKE key distribution function silc_ske_process_key_material
6389 when the key length is more than 128 bits. The default key
6390 length in SILC is now 256 bits.
6392 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6393 to indicate unsupported algorithm.
6395 * Renamed rijndael.c to aes.c and all functions as well.
6397 * Fixed a long standing channel key setting bug in client library.
6398 Weird that it has never surfaced before.
6400 * Fixed bug in channel deletion. If the entire channel is removed
6401 then it must also delete the references of the channel entry
6402 from the client's channel list as the client's channel entry and
6403 the channel's client entry share same memory.
6405 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6407 * Implemented CONNECT and SHUTDOWN commands in the client.
6409 * Implemented CLOSE command to the client.
6411 * Added the function silc_idlist_find_server_by_name into the
6412 files silcd/idlist.[ch].
6414 Added the function silc_idlist_find_server_by_conn into the
6415 files silcd/idlist.[ch].
6417 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6419 * DIE command was renamed to SHUTDOWN. Updated the both code
6422 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6423 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6425 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6428 * Added function silc_server_create_connection function to create
6429 connection to remote router. My server implementation actually
6430 does not allow router to connect to normal server (it expects
6431 that normal server always initiates the connection to the router)
6432 so the CONNECT command is only good for connecting to another
6435 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6437 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6438 or some other client was kicked from the channel.
6440 Implemented the handling of the notify type to both client
6443 Implemented silc_server_send_notify_kicked to send the KICKED
6444 notify. It is used to send it to the server's primary router.
6446 * Implemented the KICK command into server and client.
6448 * Added `query' argument to the silc_idlist_get_client function
6449 to indicate whether to query the client from server or not if
6452 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6453 to indicate that the client is not channel founder.
6457 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6459 * Removed the rng context from SilcPacketContext structure and
6460 changed that the packet routine uses the Global RNG API.
6462 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Added support for quit message that client can "leave" on the
6465 channel when it quits the SILC. It is ditributed inside the
6466 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6468 Added silc_server_free_client_data that will take the
6469 signoff message as argument.
6471 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6473 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * Updated parts of the protocol specification to keep it up
6478 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6480 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6481 payloads in one packet.
6483 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6484 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6485 use now the new List flag.
6487 * Also deprecated the following packet types: REPLACE_ID,
6488 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6490 * Added list support for Notify packet in server.
6492 * Added silc_server_send_notify_channel_change to send the
6493 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6494 the silc_server_send_replace_id.
6496 * Added silc_server_send_notify_nick_change to send the
6497 NICK_CHANGE notify type. Deprecates the function
6498 silc_server_send_replace_id.
6500 * Added silc_server_send_notify_join to send the JOIN notify type.
6501 Deprecates the function silc_server_send_new_channel_user.
6503 * Added silc_server_send_notify_leave to send LEAVE notify type.
6504 Deprecates the function silc_server_send_remove_channel_user.
6506 * Added silc_server_send_notify_cmode and
6507 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6508 types. Deprecates the silc_server_send_set_mode function.
6510 * Added SERVER_SIGNOFF notify type to indicate that server has
6511 quit. This means that all clients on the channel from that
6512 server will drop. This can be also used when netsplit happens.
6514 Deprecated REMOVE_ID packet type since it is not needed anymore
6517 Added silc_server_send_notify_server_signoff to send the
6518 SERVER_SIGNOFF notify type. Deprecates the function
6519 silc_server_send_remove_id.
6521 Added also silc_server_send_notify_signoff to send the
6522 SIGNOFF notify type.
6524 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6525 SILC protocol from this day on. Changed the protocol
6526 specification as well.
6528 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6529 notify type. It is used between routers to notify about
6530 topic changes on a channel.
6532 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6535 * Partly updated the protocol specification to comply with the
6536 changes now made. It is still though a bit outdated.
6538 * The JOIN notify type now takes one extra argument <Channel ID>.
6539 The packet used to be destined to the channel but now the
6540 JOIN type may be sent as list thus it is impossible to
6541 destine it to any specific channel. By adding this argument
6542 it is again possible.
6544 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6546 * Added CREDITS file. The CHANGES and CREDITS file will appear
6547 in the distribution as well.
6549 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6551 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6552 types in the server's silcd/packet_receive.c.
6554 * Implemented CMODE and CUMODE to work in router environment.
6556 * Fixed minor encoding and decoding buglet from the
6557 lib/silccore/silcmode.c.
6559 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6562 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6564 * Changed all SilcConfigServer* and silc_config_server* to
6565 SilcServerConfig* and silc_server_config*, respectively.
6568 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6570 * Associated the ID (client or server ID) to the Authentication
6571 Payload to avoid any possibility of forging. Updated the
6572 protocol specification and the code accordingly.
6574 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6576 * The RSA key length is now save to the RsaKey context in the
6577 key generation process in lib/silccrypt/rsa.c. The key length
6578 is now used to figure out the maximum size of the block allowed
6579 to be encrypted/signed.
6581 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6582 is equivalent to the silc_mp_mp2bin but does not allocate any
6585 * Changed silc_mp_mp2bin API to take length argument. If it is
6586 non-zero then the buffer is allocated that large. If zero, then
6587 the size is approximated using silc_mp_sizeinbase, which however
6590 * Created Global RNG API which is global RNG that application can
6591 initialize. After initializing, any routine anywhere in the
6592 code (including library) can use RNG without allocating a new
6593 RNG object. This was done to allow this sort of use of the
6594 RNG in code that has no chance to allocate RNG object. All
6595 applications currently allocate this and many routines in the
6596 library use this. Affected file lib/silccrypt/silcrng.[ch].
6598 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6599 it to use the Global RNG API.
6601 * Defined Authentication Payload into protocol specification that
6602 is used during SILC session to authenticate entities. It is
6603 used for example by client to authenticate itself to the server
6604 to obtain server operator privileges.
6606 Implemented this payload into the lib/silccore/silcauth.[ch].
6607 Implemented also routines for public key based authentication
6608 as the new protocol specification dictates.
6610 Moved definitions of different authentication methods from
6611 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6613 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6614 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6615 silc_pkcs_verify_with_hash functions into the file
6616 lib/silccrypt/silcpkcs.[ch].
6618 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6620 * The client entry's userinfo pointer must be always valid.
6621 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6622 will fail since it requires the userinfo. Now, the userinfo
6623 is allocated as "" if actual userinfo does not exist. Actually,
6624 it must exist and it is totally Ok to drop client connections
6625 that does not announce the userinfo. However, we will make
6626 this workaround for now.
6628 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6629 to return the remote port by socket.
6631 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6634 SILC_SERVER_PENDING_EXEC and added an new macro
6635 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6636 data or when error occurs while processing the pending command.
6638 Added new argument `destructor' into silc_server_command_pending
6639 and to the SilcServerCommandPending object. This destructor is
6640 now called after calling the pending callback or if error occurs
6641 immediately. If error occurs the actual pending callback won't
6642 be called at all - only the destructor. The destructor may be
6643 NULL if destructor is not needed.
6645 All this applies for client library code as well. Similar
6646 changes were made there as well for the pending commands.
6648 In the client, the application must now allocate the
6649 SilcClientCommandContext with the silc_client_command_alloc
6652 * Added reference counter to the SilcServerCommandContext. Added
6653 function silc_server_command_alloc and silc_server_command_dup
6656 Same type of functions added to the client library for the same
6659 * Removed the cmd_ident from IDListData away since it is now
6660 global for all connections. It is the command identifier used
6661 in command sending and with pending commands. The affected file
6664 * Added reference counter to the SilcSocketConnection objecet to
6665 indicate the usage count of the object. The object won't be
6666 freed untill the reference counter hits zero. Currently only
6667 server uses this, and client ignores it. The client must be
6668 set to use this too later. The affected files are
6669 lib/silccore/silcsockconn.[ch]. Added also the function
6670 silc_socket_dup to increase the reference counter.
6672 This was mainly added because it is possible that the socket
6673 is removed underneath of pending command or other async
6674 operation. Now it won't be free'd and proper DISCONNECTING
6675 flags, etc. can be set to avoid sending data to connection that
6676 is not valid anymore.
6678 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6679 the connection. After that it sets SILC_SET_DISCONNECTED.
6680 It is, however, possible that the socket data is not still freed.
6681 The silc_server_packet_process now checks that data is not
6682 read or written to connection that is DISCONNECTED. The socket
6683 get's freed when the reference counter hits zero.
6685 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6687 * Changed the client operation API: channel_message operation's
6688 `sender' is now the client entry of the sender, not the nickname
6689 and the `channel' is the channel entry, not the channel name.
6691 In the private_message operation the `sender' is now also the
6692 client entry of the sender not the nickname.
6694 Affected file is lib/silcclient/ops.h and all applications
6695 using the client operations.
6697 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6699 * Moved the calling of ops->connect() from connect_to_server_final
6700 into receive_new_id functin since that is the point when the
6701 client is actually allowed to send traffic to network. The
6702 affected file is lib/silcclient/client.c.
6704 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6706 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6707 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6708 (if needs broadcasting) instead of broadcasting the packets one
6709 by one which would make a burst in the network traffic.
6711 * Added `broadcast' argument to the functions in silcd/server.[ch]
6712 silc_server_create_new_channel[_with_id] to indicate whether
6713 to send New Channel packet to primary router.
6715 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6717 * Added new function into the silcd/server.[ch] files:
6718 silc_server_create_new_channel_with_id to create new channel with
6719 already existing Channel ID.
6721 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6722 lib/silccore/silcpacket.h. This packet is used t send list of
6723 Set Mode payloads inside one packet. Server uses this to set
6724 the modes for the channels and clients on those channels, that it
6725 announced to the router when it connected to it. The protocol
6726 specification has been updated accordingly.
6728 * The silc_server_new_channel did not handle the packet coming
6729 from normal server as it normally does not send that. However,
6730 when it announces its channels it does send it. Implemented
6731 the support for that.
6733 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6734 into the file lib/silccore/id.h.
6736 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6738 * Fixed memory leaks in the functions silc_idlist_del_client,
6739 silc_idlist_del_channel and silc_idlist_del_server in the file
6740 silcd/idlist.c. All of those leaked like a sieve.
6742 * Fixed some small memory leaks in the client's function
6743 silc_client_notify_by_server.
6745 * Added functions into silcd/server.c: silc_server_announce_clients,
6746 silc_server_announce_channels and silc_server_announce_server.
6747 These functions are used by normal and router server to announce
6748 to its primary router about clients, channels and servers (when
6749 router) that we own. This is done after we've connected to the
6752 These functions effectively implements the following packet types:
6753 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6754 and SILC_PACKET_NEW_ID_LIST.
6756 * Added new functions into the silcd/packet_receive.[ch]:
6757 silc_server_new_id_list, silc_server_new_channel_list and
6758 silc_server_new_channel_user_list to handle the incoming
6759 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6761 * Added support of changing Channel ID in the function
6762 silc_server_replace_id. If the server that announces a channel
6763 to the router already exists in the router (with same name but
6764 with different Channel ID), router is responsible to send
6765 Replace ID packet to the server and force the server to change
6766 the Channel ID to the one router has.
6768 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6769 client that the Channel ID has been changed by the router. The
6770 normal server sends this to the client. Client must start using
6771 the new Channel ID as the channel's ID.
6773 Implemented handling of this new type into lib/silcclient/client.c
6774 into the function silc_client_notify_by_server.
6776 * Added new function silc_idlist_replace_channel_id into the files
6777 silcd/idlist.[ch] to replace the Channel ID.
6779 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6781 * Call silc_server_command_identify_check always when processing
6782 the IDENTIFY command in silcd/command.c
6784 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6786 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6787 send keepalive packets. The packet can be sent by clients,
6788 servers and routers.
6790 Added function silc_socket_set_heartbeat into the file
6791 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6792 If not set, the heartbeat is not performed. The actual
6793 heartbeat is implemented in the low level socket connection
6794 library. However, application is responsible of actually
6797 Added silc_server_send_heartbeat to send the actual heartbeat
6798 packet into silcd/packet_send.[ch]. Server now performs
6799 keepalive with all connections.
6801 * Added silc_task_get_first function into lib/silcutil/silctask.c
6802 to return the timeout task with shortest timeout. There was a bug
6803 in task unregistration that caused problems. TODO has been
6804 updated to include that task system must be rewritten.
6806 * The client library will now resolve the client information when
6807 receiving JOIN notify from server for client that we know but
6808 have incomplete information.
6810 * Rewrote parts of silc_server_remove_from_channels and
6811 silc_server_remove_from_one_channel as they did not remove the
6812 channel in some circumstances even though they should've.
6814 * Encryption problem encountered in server:
6816 The LEAVE command used to send the Channel Key packet to the
6817 router immediately after generating it. However, the code
6818 had earlier sent Remove Channel user packet but not immediately,
6819 ie. it was put to queue. The order of packets in the router
6820 was that Channel Key packet was first and Remove Channel User
6821 packet was second, even though they were encrypted in the
6822 reverse order. For this reason, MAC check failed. Now, this
6823 is fixed by not sending the Channel Key packet immediately but
6824 putting it to queue. However, this is more fundamental problem:
6825 packets that are in queue should actually not be encrypted
6826 because packets that are sent immediately gets encrypted
6827 actually with wrong IV (and thus MAC check fails). So, packets
6828 that are in queue should be encrypted when they are sent to
6829 the wire and not when they put to the queue.
6831 However, the problem is that the current system has not been
6832 designed to work that way. Instead, the packet is encrypted
6833 as soon as possible and left to the queue. The queue is then
6834 just purged into wire. There won't be any fixes for this
6835 any time soon. So, the current semantic for packet sending
6838 o If you send packet to remote host and do not force the send
6839 (the packet will be in queue) then all subsequent packets to the
6840 same remote host must also be put to the queue. Only after the
6841 queue has been purged is it safe again to force the packet
6844 o If you send all packets immediately then it safe to send
6845 any of subsequent packets through the queue, however, after
6846 the first packet is put to queue then any subsequent packets
6847 must also be put to the queue.
6849 Follow these rules and everything works fine.
6851 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6853 * Added new function silc_server_remove_clients_by_server to
6854 remove all client entries from ID list when the server connection
6855 is lost. In this case it is also important to invalidate all
6856 client entires as they hold the invalid server entry. This
6857 fixes fatal bug when server has lost connection and will reconnect
6860 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * Made some sanity checks to silc_server_daemonise like to check
6863 whether the requested user and group actually exists.
6865 * Added sanity check to SKE's silc_ske_responder_finish to check
6866 that the public and private key actually is valid.
6868 * Invalidate the client's nickname when receiving Replace ID
6869 packet and the Client ID is being replaced. This means that the
6870 server will query the nickname if someone needs it (client)
6873 * Sort the ID Cache in client library when the ID Cache data
6874 has changed (needs sorting).
6876 * Do not allow for SILC client to create several connections to
6877 several servers. The client does not support windows right now
6878 and generating multiple connections causes weird behaviour.
6880 Irssi-silc client does support windows and can handle several
6881 connections without problems, see: www.irssi.org and SILC plugin.
6883 * Fixed some places where client was added to the IDList. The
6884 rule of thumb is following (in order to get everything right):
6885 If the client is directly connected local client then the
6886 `connection' argument must be set and `router' argument must be
6887 NULL to silc_idlist_add_client function. If the client is not
6888 directly connected client then the `router' argument must
6889 bet set and the `connection' argument must be NULL to the
6890 silc_idlist_add_client function.
6892 * The funtion silc_server_packet_send_local_channel actually did
6893 not check whether the client was locally connected or not. It
6894 does that now. Fixed a bug related to LEAVE command.
6896 * Fixed Remove Channel User payload parsing bug in server's
6897 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6899 * The server's silc_server_save_channel_key now checks also the
6900 global ID list for the channel as it might not be in the local
6901 list. Fixed a bug related to LEAVE command.
6903 * Is this the end of the [<unknown>] buglet that has been lurking
6904 around for a long time? A little for loop fix in server's
6905 silc_server_command_whois_parse that is used by both IDENTIFY
6906 and WHOIS command. At least, this was a clear bug and a cause
6907 of one type of [<unknown>] buglet.
6909 * WHOIS and IDENTIFY commands call the function
6910 silc_server_command_[whois/identify]_check function even if
6911 we are not router server.
6913 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6915 * Added --with-gmp configuration option. If set the GMP
6916 is always compiled in the SILC source tree. If not set then
6917 it is checked whether the system has the GMP3 installed. If
6918 it has then the GMP won't be compiled (the system's headers
6919 and library is used), if it doesn't have it then the GMP is
6920 compiled in the SILC source tree.
6922 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6924 * Changed RSA private exponent generation to what PKCS #1
6925 suggests. We try to find the smallest possible d by doing
6926 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6927 not security fix but optimization.
6929 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Added new config entry [Identity] to fork the server and run
6932 it as specific user and group. A patch from Bostik.
6934 * Imported Dotconf configuration library into lib/dotconf.
6935 This will be used to create the SILC configuration files later.
6936 It will appear in the distsribution after this commit.
6938 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6940 * A big code auditing weekend happening. Auditing code for
6941 obvious mistakes, bugs and errors. Also, removing any code
6944 Removed files for being obsolete:
6946 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6947 inline in the file lib/silcutil/silcbuffer.h)
6949 o lib/silcutil/silcbufutil.c (the header has inline versions)
6951 Changed code to fix possible error conditions:
6953 o The buffer formatting routines now check that the destination
6954 buffer really has enough space to add the data. This applies for
6955 both buffer formatting and unformatting
6956 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6957 unformatting was changed to accomodate following rules:
6958 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6959 sent to the function while XXX_*STRING will not allocate or copy
6960 the data into the buffer. Instead it sets the pointer from the
6961 buffer into the pointer sent as argument (XXX_*STRING used to
6962 require that the pointer must be allocated already). This change
6963 makes this whole thing a bit more consistent and more optimized
6964 (note that the data returned in the unformatting with XXX_*STRING
6965 must not be freed now). The routines return now -1 on error.
6967 o Tried to find all code that use buffer_format and buffer_unformat
6968 and added return value checking to prevent formatting and
6969 especially unformatting errors and possible subsequent fatal
6972 o Changed ske->x and ske->KEY to mallocated pointers in
6973 lib/silcske/silcske.h. Fixed possible data and memory leak.
6975 o Added return value checking to all *_parse* functions. Fixed
6976 many memory leaks as well.
6978 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6979 so that buffer overflows would not happen. All code now also
6980 checks the return value as it can fail.
6982 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6984 * Added reconnection support to server if the normal server looses
6985 its connection to the router (for example if router is rebooted).
6986 The server performs normal reconnection strategy implemented
6987 to the server. Affected file silcd/server.c.
6989 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6991 * Added new packet type SILC_PACKET_SET_MODE that is used to
6992 distribute the information about changed modes (for clients,
6993 channels and clients channel modes) to all routers in the
6994 network. Updated the protocol specification accordingly.
6996 Added functions into silcd/packet_send.c and
6997 silcd/packet_receive.c: silc_server_send_set_mode,
6998 silc_server_set_mode.
7000 Added new files silcmode.[ch] into lib/silccore that implements
7001 the encoding and decoding of Set Mode Payload. Added new type
7002 SilcSetModePayload. Moved the definitions of different modes
7003 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7005 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7007 * Oops, a little mistake in server's connection authentication
7008 protocol. The protocol is not ended with FAILURE but with
7009 SUCCESS if the authentication is Ok. :) Affected file is
7012 * Implemented NICK_CHANGE notify handling in server in the file
7013 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7014 the local clients on the channel. After the changing nickname
7015 in router environment snhould work and the [<unknown>] nickname
7016 should appear no more.
7018 The silc_server_replace_id function that receives the Replace ID
7019 payload now sends the NICK_CHANGE notify type also in the file
7020 silcd/packet_receive.c
7022 * Changed WHOIS and IDENTIFY command to support the maximum amount
7023 of arguments defined in protocol specs (3328 arguments). This
7024 fixed a bug that caused problems when there were more than three
7027 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7029 * Added extra parameter, command identifier, to the
7030 silc_client_send_command so that explicit command identifier
7033 Changed that ID list routines uses specific command identifier
7034 when sending WHOIS/IDENTIFY requests to the server so that they
7035 can be identified when the reply comes back.
7037 Affected files lib/silcclient/command.[ch],
7038 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7040 * Added `sender' argument to silc_server_packet_send_to_channel
7041 to indicaet the sender who originally sent the packet to us
7042 that we are now re-sending. Ignored if NULL. Affected file
7043 silcd/packet_send.[ch].
7045 * Added some server statistics support in silcd/server_internal.h
7046 SilcServerStatistics structure and around the server code. Also
7047 send some nice statistics information when client is connecting
7050 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7052 * Fixed channel ID decoding in server's JOIN command reply in
7053 silcd/command_reply.c
7055 * Fixed braodcasting of replace ID payload to not to send it if
7056 we are standalone server in silcd/packet_receive.c.
7058 * Fixed all channel message sending routines to not to send
7059 packets to clients that has router set, since they are routed
7060 separately in the same function earlier. Affects file
7061 silcd/packet_send.c and all channel packet sending functions.
7063 * In USERS reply, res_argv[i] are not allocated, the table
7064 is allocated. Thus changed that free the table, not its
7067 * In server's whois_check and identify_check if the client is
7068 locally connected do not send any WHOIS commands - they are not
7071 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7073 * Fixed some minor bugs in client when sending WHOIS command. The
7074 arguments was in wrong order.
7076 * Removed statis function add_to_channel from server in
7077 silcd/command.c that was previously used with the joining but
7080 * Tested USERS command in router environment successfully with two
7081 routers, two servers and two clients.
7083 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * Reorganized the USERS command and command reply in client library
7086 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7087 When the command is given by user we register a pending command
7088 callback that will reprocess the command after the reply has been
7089 received from the server. When reprocessing the packet we then
7090 display the information. Thus, the USERS information is displayed
7091 now in the command callback instead of in the command reply
7092 callback. The processing of the command is same as previously
7093 when server has sent the command reply in the JOINing process.
7095 * Added to USERS command in silcd/command_reply.c to join the client,
7096 we didn't use to know about, to the channel after we've created
7097 a client entry for it. Also, for clienet we did know already still
7098 check whether it is on the channel or not and add it if not.
7100 * Removed silc_server_command_join_notify as the function and its
7103 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7105 * Changed the client's pending command handling to the same as the
7106 server's pending command handling. It is also now possible to
7107 execute command reply functions from other command reply
7108 function as the function callbacks for commands and command
7109 replies are one and same. The pending commands are not static
7110 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7111 in client connection context. Thus, pending commands are server
7112 connection specific as it is convenient.
7114 Changed the function silc_client_command_pending and
7115 silc_client_command_pending_del and added new function
7116 silc_client_command_pending_check. Removed the
7117 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7120 * Added cmd_ident, current command identifier, to the client
7121 connection context in lib/silcclient/client.h to keep track on
7122 command identifiers used in command sending. Client's command reply
7123 function handling now supports the mandatory command identifiers.
7125 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7126 funtions in client to fully support pending command callbacks.
7128 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7129 as one of the arguments to the application in the command reply
7132 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7133 before first releasing SILC but came back. Now it is removed again
7134 and should come back nomore. The FORWARDED flag was used only
7135 by the JOINing procedure by forwarding the command packet to router.
7136 Now, the JOINing procedure has been changed to more generic (due
7137 to various router environment issues) and FORWARDED is not needed
7138 anymore for anything. The protocol specification is yet to be
7141 Now, removed silc_server_packet_forward from server and the flag
7142 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7144 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7146 * Renamed NAMES command to USERS command. The NAMES was named that
7147 due to historical reasons. Now it is renamed. Also, rewrote
7148 parts of the USERS command. The nickname list is not sent anymore
7149 by the server. Only Client ID and mode lists are sent in the USERS
7150 command. Changed this also to the protocol specification.
7152 The client now resolves the names and stuff after it receives
7153 the USERS list from the server when joining to the channel.
7155 * WHOIS and IDENTIFY commands has been changed to support multiple
7156 Client ID's per command. One can now search for multiple users
7157 in the network by sending only one WHOIS or IDENTIFY command.
7158 Changed the code and the protocol specifications.
7160 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7161 uses silc_server_command_whois_parse to parse the request. */
7163 * If normal server, do not parse the WHOIS and IDENTIFY requests
7164 before sending it to the router. Saves some time.
7166 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7168 * Fixed JOIN command on client library. Wrong number of arguments
7169 used to crash the client.
7171 * Added silc_server_channel_has_global function to check whether
7172 channel has global users or not.
7174 * Added silc_server_channel_has_local function to check whether channel
7175 has locally connected clients on the channel.
7177 * The silc_server_remove_from_one_channel now checks whether the
7178 channel has global users or not after given client was removed from
7179 the channel. It also checks whether the channel has local clients
7180 on the channel anymore. If it does not have then the channel entry
7181 is removed as it is not needed anymore.
7183 * The silc_server_notify now checks on JOIN notify whether the joining
7184 client is one of locally connected or global. If it is global then
7185 the channel has now global users on the channel and that is marked
7186 to the channel entry. Also, it now saves the global client to
7187 global list who is joining and JOINs it to the channel. This is
7188 for normal server, that is.
7190 Changed silc_server_send_notify_on_channel,
7191 silc_server_packet_relay_to_channel and
7192 silc_server_packet_send_to_channel check if we are normal server
7193 and client has router set (ie. global client) do not send the
7194 message to that client, as it is already routed to our router.
7196 * Implemented LEAVE notify type handling in silc_server_notify
7199 * Tested LEAVE command in router environment successfully. Tested
7200 with two routers, two servers and two clients.
7204 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7206 * Implemented SIGNOFF notify type handling in silc_server_notify
7209 * silc_server_remove_id now removes the client entry from all channels
7210 it has joined and thusly sends SIGNOFF notify type.
7212 * Rewrote the NAMES list generation in server by removing two excess
7213 loops. The lists are created now inside one loop.
7215 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7217 * silc_server_remove_channel_user checks now also global list
7218 for channel and client.
7220 * silc_server_new_channel_user checks now both local and global
7221 list for channel and client. Fixed a bug in client id decoding.
7222 Used to decode wrong buffer.
7224 * silc_server_channel_message checks now both local and global
7225 list for channel entry.
7227 * Tested channel joining (hence JOIN) in router environment
7228 successfully. Tested with two routers, two servers and two
7231 * Tested channel message sending in router environment successfully.
7233 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7235 * Added silc_server_save_channel_key into server.[ch] to save the
7236 received channel key in Channel Key payload processing. It is
7237 also used in JOIN command reply handling.
7239 Equivalent function silc_client_save_channel_key added into
7240 client.[ch] into client library.
7242 * Changed JOIN command reply to send information whether the channel
7243 was created or not (is existing already) and the channel key
7244 payload. Changed protocol specs accordingly.
7246 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7247 the request was sent by ID and not by nickname. Crashed on
7250 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7252 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7253 now correctly save the received data.
7255 * silc_server_free_sock_user_data now notifies routers in the
7256 network about entities leaving the network.
7258 At the same time implemented functions silc_server_remove_id
7259 and silc_server_send_remove_id to receive and send REMOVE_ID
7260 packets. The packet is used to notify routers in the network
7261 about leaving entities. The ID removed will become invalid in
7264 * Added function silc_idlist_del_server into server. Removes and
7265 free's server entry from ID list.
7267 * silc_server_private_message function now checks, if we are router,
7268 that the destination ID really is valid ID, naturally.
7270 * In router when NEW_ID packet is received (for new client) the
7271 hash of the Client ID is saved in the ID Cache but the
7272 client->nickname is set to NULL, instead of putting the hash
7275 IDENTIFY command now also checks that client->nickname must be
7276 valid. If it is not if will request the data from the server who
7277 owns the client. Added new function
7278 silc_server_command_identify_check.
7280 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7281 to set the command to already allocated Command Payload.
7283 * Tested private message sending in router environment with two
7284 routers, two servers and two clients. Fixed minor bugs and now
7287 * Fixed segfault from client's NAMES command. Used to crash if
7290 * Forwarded packets must not be routed even if it is not destined
7291 to the receiver. Changed server code comply with this.
7293 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7295 * Added `require_reverse_mapping' boolean value to ServerParams
7296 structure. If TRUE (not default) the server will require that
7297 the connecting host has fully qualified domain name.
7299 If the reverse mapping is not required and hostname could not be
7300 found the IP address is used as hostname.
7302 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7304 * Implemented version string checking to both client and server.
7305 The check is incomplete currently due to the abnormal version
7306 strings used in development version of SILC.
7308 * Changed all command functions in server to use the new
7311 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7313 * Changed char *data to unsigned char *data in ID Cache system to
7314 support binary data as ID Cache data. Changed code to support
7315 binary data in lib/silccore/idcache.c.
7317 * Renamed silc_server_packet_relay_command_reply to
7318 silc_server_command_reply as it is normal packet receiving
7319 function. Rewrote the function to accept command replys for
7320 servers and not only for clients.
7322 * Mark remote router always as registered server if we are connecting
7323 to it. Otherwise, commands sent by the router to us are ignored.
7325 * All ID List find routines now returns the ID Cache Entry pointer
7326 as well if requested.
7328 * WHOIS command works now in router environment, tested with two
7329 routers, two servers and two clients.
7331 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7332 in router environment (as it is almost equivalent to WHOIS) but
7333 hasn't been tested thoroughly. Added new functions:
7335 silc_server_command_identify_parse
7336 silc_server_command_identify_send_reply
7337 silc_server_command_identify_from_client
7338 silc_server_command_identify_from_server
7340 * Disabled route cache adding because adding two different ID's with
7341 same IP replaces the old cache entry thus giving wrong route.
7342 The entry->router->connection is always the fastest route anyway
7343 so route cache may not be needed. Of course, new routes maybe
7344 established after receiving the ID when the entry->router->connection
7345 might not be anymore the most optimal.
7347 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7349 * Add route cache for received ID for fast routing.
7351 * Added silc_server_packet_route to route received packet on router
7352 that is not destined to us.
7354 * Renamed silc_server_get_route to silc_server_route_get.
7356 * Added id_string and id_string_len fields into SilcServer to
7357 include encoded ServerID for fast comparing without excess
7358 encoding of the ID's.
7360 * Cleaned up WHOIS command on server side. Added following static
7363 silc_server_command_whois_parse
7364 silc_server_command_whois_check
7365 silc_server_command_whois_send_reply
7366 silc_server_command_whois_from_client
7367 silc_server_command_whois_from_server
7369 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7370 arguments in command replies. All command functions should be
7371 updated to use this macro.
7373 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7375 * Minor typo fixes on command reply handling on server.
7377 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7379 * Added silc_server_command_add_to_channel internal routine to add
7380 the client to the channel after router has created the channel and
7381 sent command reply to the server.
7383 * Added generic silc_server_send_command to send any command from
7386 * Use static buffer with ID rendering instead of duplicating data.
7388 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7390 * Fixed a channel user mode bug when joining to a channel server gave
7391 everybody channel founder rights, oops.
7393 * We mark ourselves as the router of the incoming server connection
7394 if we are router ourselves. This way we can check in some packet
7395 sending functions whether it is locally connected server. For
7396 incoming router connections we put NULL.
7398 * For router sending packets locally means now always sending the
7399 packet cell wide; to local clients and local servers. For normal
7400 server sending packet locally means sending it to only local
7403 * Fixed the JOIN command to really work in router environment. If the
7404 channel is created it is always created by the router. Router is
7405 also responsible of making the initial joining to the channel,
7406 sending JOIN notify to the sending server and distributing
7407 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7408 does not exist server doesn't do anything else but forward the
7409 command to the router which performs everything.
7411 * Added silc_server_send_channel_key function to send the Channel Key
7414 * Added silc_server_create_channel_key to create new channel key. The
7415 channel key is now re-generated everytime someone joins or leaves
7416 a channel, as protocol dictates. Note: channel->key_len is the
7419 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7421 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7422 packet_receive.[ch] to separate packet sending and receiving
7423 routines. The server.[ch] now includes everything else including
7424 actual packet processing (writing and reading data) and other
7427 Renamed silc_server_private_message_send_internal to
7428 silc_server_send_private_message. The routine is still though
7429 used only to relay private messages as server does not send
7430 private messages itself.
7432 Renamed silc_server_new_channel to silc_server_create_new_channel
7433 and added new function sicl_server_new_channel that handles the
7434 incoming New Channel packet. Added also new sending function
7435 silc_server_send_new_channel to send New Channel Payload.
7437 * Added new function silc_server_notify to process incoming notify
7438 packet to the server/router. Server may then relay the notify
7439 to clients if needed.
7441 * Added new function silc_server_new_channel_user to process incoming
7442 New Channel User packet. Router will redistribute the packet and
7443 send JOIN notify to its local clients and locally connected servers
7444 if needed. Normal server will send JOIN notify to its local client
7445 on same channel when received this packet. Added also corresponding
7446 sending function silc_server_send_new_channel_user to sent the
7449 * Added boolean route argument to send_notif_to_channel and
7450 packet_send_to_channel functions to attempt to route the packet
7451 if it is TRUE and send only locally if it is FALSE.
7453 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7455 * silc_server_replace_id now broadcasts the received replace ID
7456 packet if it is not broadcast packet already. The router must
7457 broadcast to inform other routers about changed ID.
7459 * Added backpointer to server's router into SilcServer context in
7460 silcd/server_internal.h.
7462 * Fixed silc_server_packet_broadcast to send correct broadcast
7465 * The channel key is now distributed to the local client as soon
7466 as it is received from the router (in router environment) so that
7467 no other packet may be sent for the channel until client has
7470 * silc_server_remove_channel_user now broadcasts the received
7471 Remove Channel User packet if it is not broadcast packet already.
7472 The router must broadcast to inform other routers about removed
7475 * Added users field into SilcPacketContext that is a reference count
7476 of the context. One can increase the reference count by calling
7477 silc_packet_context_dup which is now changed to just increase the
7478 reference count instead of duplicating the data. The reference
7479 count is decresed by calling silc_packet_context_free that will
7480 free the data after the reference count hits zero.
7482 For now on the packet context and everything allocated into it
7483 (including the raw packet from network) must be freed by calling
7484 the new silc_packet_context_free function. Added also new function
7485 silc_packet_context_alloc that must be used now to allocate the
7486 context. This also means that if a routine is asynchronous from
7487 silc_[client/server]_packet_parse_type the packet context must
7488 be duplicated by calling silc_packet_context_dup. Otherwise it
7489 gets free'd after silc_[client/server]_packet_parse_type returns.
7490 Also, one must remember that if packet is duplicated then its
7491 reference count must be decresed by calling the free function as
7492 many times as it was duplicated.
7494 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7495 from both client and server.
7497 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7499 * Made joining to a channel working in router environment.
7501 * Cleaned up JOIN command on server side and create function
7502 silc_server_command_join_channel internal routine to make the
7505 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7507 * Changed silc_command_pending list to SilcDList. Also, added
7508 `ident' field to SilcServerCommandPending structure to identify
7509 the reply and to call correct callback.
7511 Added silc_server_command_pending_check function to replace the
7512 corresnponding macro. The silc_command_pending list is not
7515 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7516 to set identifier to previously allocated Command Payload. It
7517 is used to set identifier for command when resending Command
7520 * Added silc_command_payload_encode_payload to encode Command
7521 Payload buffer from SilcCommandPayload structure.
7523 * Added silc_argument_payload_encode_payload to encode Argument
7524 payload buffer from SilcArgumentPayload structure.
7526 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7528 * Changed WHOIS command to support router connection on server side.
7529 The whois request is always sent to router unless the server is
7530 standalone server. After server has received the reply from the
7531 router will it send the reply to the client.
7533 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7534 broadcast received broadcast packet. The function is used only
7535 by router. The broadcast packet is always sent to the router's
7538 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7539 render given ID to printable string, for log files for example.
7541 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7543 * Made basic router to router connections working. At least they
7544 can now connect to each other but nothing really works the way
7545 they are supposed - yet.
7547 * Added new initiator token to RouterConnection configuration
7548 file in silcd/serverconfig.[ch]. It is used to tell whether we
7549 are the initiator to the remote router or whether we'll expect
7550 the other end to connect.
7552 * Moved registering of listener task to silc_server_init, hence
7553 the server starts listenning as soon as it is run, even if it
7554 does not have connections to other routers. Let's see how well
7557 * Changed default connection retry timeouts for more suitable in
7560 * Removed cipher and such arguments from silc_idlist_add_client
7561 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7562 Added new function silc_idlist_add_data to add the keys and stuff
7565 * Added SilcIDListData structure and added it to SilcClientEntry
7566 and SilcServerEntry as their first field in the structure. This
7567 way we can explicitly cast the ID entries to the SilcIDListData
7568 structure and get common data for the entries. In past, we had
7569 to first check what type of connection it is and then cast it to
7570 correct ID entry type. Now, we can directly cast the opaque
7571 pointer to the SilcIDListData (no matter what ID entry it actually
7572 is) and get the data needed.
7574 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7576 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7577 in some circumstances even if threre were timeout tasks, though not
7578 IO tasks, but tasks anyway. Now fixed.
7580 * Defined SilcServerConnection structure to hold connection specific
7581 stuff about directly connected servers and routers. The definition
7582 is currently in silcd/server_internal.h. I thought about having
7583 a bit more important role fro this struct but for now it is used
7584 only when connecting to other server (or router actually).
7586 * Added connecting retry support in server when connecting to
7587 router(s). The retry feature implement exponential backoff
7588 algorithm. Also, added SilcServerParams structure to hold default
7589 parameters for server. For now, it include these retry settings
7590 and are hard coded. After server is moded to be as Silc Server
7591 Library this structure will be more important.
7593 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7595 * Changed client librarys channel->clients table to SilcList and
7596 changed code accordingly.
7598 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7600 * Changed client's channel table to SilcList and changed code
7601 accordingly. Also changed SilcChannelClientEntry to include back-
7602 pointer to the channel so that client entry can use that structure
7603 as list as well and we have fast cross-reference to the channel.
7604 This change dramatically decreased the complexity of channel
7605 handling with client entry and vice versa (removed one extra
7606 loop when searching for channel entry from many functions).
7608 * Changed server->sim from table to SilcDList and changed code
7611 * NAMES command can now be used from user interface. It will show
7612 the user list on the channel, neatly.
7614 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7615 Code now saves realname of the user if it becomes available.
7617 * Renamed configure.in to configure.in.pre and made ./prepare
7618 script to automatically add correct version string to
7619 configure.in which it creates from configure.in.pre.
7621 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7623 * NAMES command reply now shows users mode with the nickname when
7626 * Moved silc_client_ch[u]mode[_char] functions from
7627 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7628 place sucks, they are utility functions and should be in some
7631 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7633 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7636 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7640 * Added TRQ (efficient deque and list library) into lib/trq. This is
7641 a very good list library that is currently used in the SILC. Defined
7642 SilcList API over the library because I didn't like the API very
7643 much. See lib/trq/silclist.h for the API and examples of how to
7644 use the API. Fixed various places in the code to use the new
7645 SilcList API. The SilcList is meant for lists that has a structure
7646 already defined as a list. It is not suitable to add just some
7647 context to the list (in TRQ, the context is the list actually).
7649 So, I defined SilcDList that can be used for the purpose where
7650 predefined list structure does not exit. This can be used as
7651 such list. Now some context just can be added to the SilcDList.
7652 Currently this list is not used in the SILC just yet, though there
7653 are a lot places where this can replace dynamically allocated
7654 tables and I will fix these places, later, to use SilcDList.
7655 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7656 and use TRQ internally).
7658 Also fixed some annoying warning messages that the original TRQ
7659 code generated. Also minor changes to TRQ's Makefile.in.
7661 * Added support for querying by Client ID to both WHOIS and
7662 IDENTIFY commands into server, as required by the protocol.
7664 * Removed method function pointers from SilcBuffer structure. They
7665 weren't used to anything and just increased the context size for
7666 no good reason. This change also made silc_buffer_alloc and
7667 silc_buffer_free functions inline functions.
7669 * Disabled command flooding detection support until it's fixed so
7670 that it accepts commands in but does not execute them more than once
7673 * Added silc_net_localhost(), to return local hostname, into
7674 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7675 that must be initialized before calling silc_client_init.
7677 * Added new function: silc_server_send_notify_on_channels to send
7678 notify messages to all channels client has joined. It is assured
7679 that the message is sent only once per client.
7681 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7682 lib/silcutil/silcutil.[ch] as silc_format function. The new
7683 function is generic and is used by server as well, not only by
7684 the logging routines.
7686 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7687 the provided version string was not acceptable. Added new function:
7688 silc_ske_check_version into lib/silcske/silcske.h. The function
7689 must be implemented by the application (client or server) and it
7690 does not reside in the SKE library. The function checks the version
7691 string remote end sent.
7693 * Added back pointers (to opaque context and to SilcSocketConnection)
7694 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7696 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7697 duplicate packet context structure.
7699 * Changed `notify' client operation to send same arguments as client
7700 receives from server except for ID's. ID's are mapped to correct
7701 ID entry and that is returned. Also, if channel entry is not sent
7702 by server but the notify is for channel the channel entry is sent
7703 to application (otherwise application doesn't know that it is for
7704 channel (library gets it from packet's Destination ID)).
7706 * Added silc_client_remove_from_channels into client library to
7707 remove a client from all channels it has joined to. Used when
7708 received SIGNOFF notify from server. Added also new function
7709 silc_client_replace_from_channels to replace old ID entry with
7710 new ID entry on all channels. Used when received NICK_CHANGE
7713 * Fixed ID Cache list handling in silc_idlist_get_client in
7714 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7715 to get (or query) client by ID.
7717 * Updated TODO list.
7719 * Added connection authentication status message defined by the
7720 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7721 support for these into the code in client and server side.
7723 * Added generic function silc_client_send_command to send any command
7724 with variable argument list. Application should use this function
7725 to send commands if the command functions provided by the library
7726 does not suite for the application's user interface needs.
7728 * Added new `failure' client operation. Application is notified about
7729 received failure packet if client is executing a protocol. In this
7730 case the protocol's execution has failed.
7732 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7733 is required by the protocol.
7735 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7736 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7739 * Added status flag to SilcSKE object to indicate realtime status
7740 of the SKE protocol.
7742 * Application receives now exactly same command reply arguments as
7743 the library receives from server. However, if ID is received the
7744 corresponding ID entry is returned to the application (eg. Client
7745 ID is mapped to correct SilcClientEntry entry and that is returned).
7746 Changed command_reply client operation due to this change.
7748 * Changed all ID's in commands and in command replys as ID Payloads.
7749 Change affected both client and server side codes.
7751 All ID's sent in SILC network (with execption of ID's in SILC
7752 Packet header) are sent in ID Payload to support variable length
7755 * Server now notifies nick changes and notifies all clients on
7756 the channels about the new nickname (about the new Client ID,
7759 * Implemented CMODE command to change channel modes. Supports all
7760 channel modes defined by the protocol specs except ban and invite
7761 lists. (Also, private channel key mode is supported but support for
7762 setting private channel key in client is missing, thus, this mode
7763 has no effect on client side (except that server requires that the
7764 client uses private channel key and normal channel traffic does not
7767 Also, invite mode works per se, but INVITE command does not work
7768 yet correctly, so you can set channel as invite only channel but
7769 inviting clients to the channel does not work (it is yet to be
7770 thought what's the best way to do it).
7772 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7773 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7774 Implemented CUMODE command to change user's mode on the channel.
7775 Supports all modes defined by the protocol specs.
7777 * Added NAMES command reply to return users modes on the channel.
7779 * Removed unnecessary and slow ciphers from lib/silccrypt.
7781 * Set SO_KEEPALIVE option to connection sockets by default.
7783 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7785 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7786 redefined the Notify Payload into protocol specs.
7788 * Added silc_id_payload_parse_id to get ID directly from raw
7791 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7793 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7794 accept searching by Client ID as well.
7796 * Added support for LEAVE and SIGNOFF notify types in client library.
7798 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7799 to parse ID Payload from raw data.
7801 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7803 * Added flags parameter into silc_ske_assemble_security_properties
7804 function in lib/silcske/silcske.[ch].
7806 * Changed notify client operation to fit better for notify messages
7807 sent by server. The notify payload received from server is now
7808 passed to the application (after parsing it to SilcNotifyPayload).
7809 It is application's responsibility to retrieve the arguments
7810 from the payload and show the message the way it wants. The message
7811 sent by server is implementation specific.
7813 * Changed public keys to comply with the protocol specification.
7814 Old public keys are not supported anymore and are not compatible.
7816 * Removed nickname from Channel Payload as the latest draft removed
7817 it. The client must resolve the nickname from the NAMES command
7818 reply received when it joined the channel.
7820 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7822 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7824 * Fixed some errors in protocol specification drafts.
7826 * Created lib/silccore/silcnotify.c to implement Notify Payload
7827 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7828 generic payloads described by protocol specifications. The file
7829 includes implementations for ID Payload and Argument Payload.
7831 * Changed Command Payload implementation to use the new Argument
7832 Payload. Changed command_xxxx_payload to command_payload_xxxx
7833 to comply with SILC coding conventions.
7835 * Added suppport for Argument Payload handling in Notify Payload
7836 implementation as protocol requires it. Added the new support
7837 into server and client lib as well.
7839 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7841 * Added support for multiple nicknames on same channel. [n] is
7842 added locally to the nickname if there are more than one same
7843 nicknames on the channel.
7845 * Server now sends all nicknames that matched WHOIS request.
7846 Client also shows the list received from server.
7848 * Added TOPIC command to client side. User can now set and show
7849 current topic on channel.
7851 * Added MOTD command to client and server. Also, server sends the
7852 motd when client connects to the server.
7854 * Changed version strings to comply ISO 8601.
7856 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7858 * Fixed protocol error handling in client library. It should now
7859 cope even if the SKE fails for some reason.
7861 * Made new protocol specification drafts for submitting to IETF.
7863 * Implemented TOPIC command to server in silcd/command.c.
7865 * Added two new notify types into lib/silccore/silcnotify.h:
7866 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7867 notify nickname change and topic setting/change on a channel.
7869 * API change of command_reply operation in client library. The
7870 application gets now the status type received from server as well.
7872 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7874 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7876 * Cras fixed and optimized the packet handling even further and
7877 it should work now. Minor change to the prototype of function
7878 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7880 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7882 * Added new function into lib/silcutil/silcschedule.[ch]:
7883 silc_schedule_with_fd to select() a specified fd. The function
7884 returns after timeout expires or data arrives or goes. The
7885 function is used by packet routines to wait that all data is
7886 received from network.
7888 * Fixed data reading from network in lib/silccore/silcpacket.c.
7889 The code now assures that all data is read from the fd and then
7890 continues packet processing. This was a bug fix since the code
7891 used to drop some data in some circumstances.
7893 * Added new function into lib/silcclient/client.[ch]:
7894 silc_client_start_key_exchange to start key exchange after
7895 connection has been established to server. The code internally
7896 now uses this funtion but its main purpose was to provide it
7897 for applications that perform their own connecting. After
7898 application has created a connection it merely calls this
7899 function to start the key exchange between client and server.
7900 The library takes care of everything else after that.
7902 Updated also lib/silcclient/README to explain the usage of
7905 * Do not send to application information that connection has
7906 been established. Application gets notified it by connect
7909 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7911 * Applied cras's patch to add silc_schedule_one function. The
7912 function runs scheduler once and returns.
7914 * Fixed the scheduler after cras messed it up. The timeout
7915 handling works now as it's supposed to work.
7917 * Added into lib/silccore/ silcnotify.h to include notify
7918 message types support. Changed silc_server_send_notify*
7919 functions, in server.[ch], to support those new notify types.
7920 Added the support for the notify types into client library,
7921 as well. Added new notify client operation into ops.h in
7924 * Changed silc_server_packet_send_to_channel to send normal
7925 packets instead of just channel message packets. The function
7926 is now used to send the notify packets to channels. It is not
7927 used to send channel message packets anymore, as server never
7930 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7931 va_arg()s as it seems to require it nowadays. I guess, if SILC
7932 is compiled with older va_arg() the new code should work anyway.
7934 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7936 * Splitted core library. Core library (lib/silccore) includes
7937 now only SILC protocol specific core (and common) components.
7938 Created new utility library (lib/silcutil) that includes more
7939 generic purpose stuff. The stuff for util library was taken
7940 from the old core library. This was minor and easy split.
7942 * Created SILC Client Library (lib/silcclient) that includes
7943 implementation of the SILC client without user interface. This
7944 was major move from silc/ directory. The code has been changed
7945 so that it is transparent towards the user interface. The
7946 silc/ directory includes now the same user interface as before
7947 and it uses the new client library. Read lib/silcclient/README.
7948 Basicly, the client library performs everything else related
7949 to SILC except user interface handling. Also, configuration
7950 files are considered to be part of user interface and library
7951 does not handle them.
7953 This change also changed a lot of structures, function naming etc.
7954 Most important change was that SilcClientWindow object was
7955 renamed to SilcClientConnection in the client library. Created
7956 also new file lib/silcclient/ops.h. Also added new files
7957 silc/local_command.[ch] and silc/client_ops.[ch].
7959 All these changes were made to make it easier for user interface
7960 designers to create what ever user interface for the SILC client
7963 It is also expected that the server will be moved to lib
7964 directory as well and SILC Server Library will be created;
7965 sometimes in the future.
7967 * Removed Local commands from lib/silccore/silccommand.h as
7968 they are application specific and new client library does not
7969 handle any of those anymore.
7971 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7972 old client implementation in silc/.
7974 * Added support for callback functions in SILC_LOG_* macros.
7975 Application can now set its own callbacks that will be called
7976 instead of using the default functions that will always print
7977 the debug messages to stderr (or stdout). Also, debugging can
7978 now be disabled by setting silc_debug to FALSE and re-enabled by
7979 setting it to TRUE. Note, that logging will still work even
7980 if debugging is disabled.
7982 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7983 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7984 silc_log_reset_debug_callbacks.
7986 * To enable debugging in silc client one must give now -d
7987 option on command line.
7989 * Changed silc_schedule_init to automatically allocate task queues
7990 if they are not allocated before calling it.
7992 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7994 * Added GMP 3.1 into math library.
7996 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7998 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7999 a channel in SILC network. The packet is used by servers and
8000 routers to notify other routers that user has left a channel.
8001 This little feature was missing until now. Added the feature
8002 to protocol specification as well.
8004 Added functions: silc_server_send_remove_channel_user and
8005 silc_server_remove_channel_user into server.[ch].
8007 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8008 lib/silccore/silcpacket.h. However, they are not implemented
8011 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8013 * Fixed joining to a channel and sending channel messages
8014 between server and router. The channel message sending should
8015 now work inside a cell.
8017 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8019 * Fixed the private message sending between server and router.
8020 The private message sending should now work inside a cell.
8022 * Added silc_server_replace_id into server.[ch] to replace
8023 existing ID in the SILC network.
8025 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8026 and silc_idlist_replace_server_id into idlist.[ch] in server.
8028 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8030 * Fixed the server to server connections. Server can again now
8031 connect to router. Router to router connections probably does
8034 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8036 * Added dynamic protocol registering support. Now protocols can
8037 registered and unregistered on the fly. Patch by cras.
8039 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8041 * Added lib/contrib directory to hold routines that some platforms
8042 don't have but are needed by SILC.
8044 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8045 into lin/contrib to provide getopt() and getopt_long() for
8046 those who don't have it.
8048 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8050 * Added AWAY command to client. When away message is set and
8051 client receives a private message packet the client automatically
8052 replies to the sender with the away message.
8054 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8055 bug seemed to be the cause of recent problems when compiling
8058 * Added version detection support to SKE protocol specification
8059 and added the new changes to the SKE implementation as well.
8060 There were other minor changes in the SKE protocol as well.
8062 Many changes in lib/silcske/silcske.[ch] and in
8063 lib/silcske/payload.[ch].
8065 * Added ^U functionality, clear input line. Patch from cras.
8067 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8069 * Mainly small bugfixes on core library. Fixed some debugging
8070 logging and buffer overflow in silclog.c.
8072 * Updated config.sub and config.guess on the distribution tree.
8074 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8076 * Added command lagging support in server. Client may execute
8077 commands now only once in two seconds.
8079 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8081 * Optimized packet reception. MAC computation and checking is now
8082 also more optimized. A lot previously duplicated code is now
8083 used as generic by both client and server.
8085 * Fixed key pair generation in clientutil.c
8087 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8089 * Added into lib/silccore/silcbufutil.[ch] new function;
8090 silc_buffer_realloc.
8092 * Moved generic packet sending/encryption functions to
8093 lib/silccore/silcpacket.[ch] from client and server. Some
8094 rewriting of the functions.
8096 * Moved all generic packet reception/decryption functions to
8097 lib/silccore/silcpacket.[ch] from client and server. The
8098 packet processing is now much cleaner in both client and server.
8099 These were major changes in both client and server.
8101 * Created many common functions in server to do packet sending.
8102 Previously code were duplicated a lot, this has been removed
8105 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8107 * Rewrote major parts of the ID cache system. Don't know
8108 whether it is better now or not but at least the API is more
8111 * Major rewrite on ID cache stuff on client because of the ID
8112 cache API changes. Added idlist.c to client.
8114 * Also major rewrite on ID cache stuff on server as well.
8115 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8116 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8117 in hand, instead they are all put into the ID cache system now.
8118 All server_idlist_* routines uses ID cache now instead of
8119 traversing its own lists (those lists does not exist anymore).
8120 SilcIDList though still exists. Also, SilcXXXEntry's are
8123 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8125 * Finally made the SKE implementation compliant to the protocol
8126 specification. All mp integers are now binary encoded as
8127 opposed being HEX encoded.
8129 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8132 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8133 functions: silc_[encode/decode]_pem. Also added function
8134 silc_encode_pem_file to PEM encode with newlines ('\n') for
8137 * SILC public keys are now encoded either PEM or binary. Same
8138 option is for private keys as well. By default private keys
8139 are binary encoded and public keys PEM encoded. Silly HEX
8140 encoding were removed.
8142 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8143 function to create fingerprints.
8145 * Fixed a bug in SHA1; does not change the original data anymore.
8147 * Partly implemented INFO command on client and server side.
8148 Fixed CLEAR command. Changes to SERVER command; show current
8149 server(s) when giving command without arguments. Added
8150 VERSION command to client.
8152 * Added check to server that unregistered connections cannot
8153 execute commands (unless it is specificly allowed).
8155 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8157 * Fixed screen refresh.
8159 * Fixed channel joining bug from client. On some circumstances
8160 client tried to join to a channel it had already joined.
8162 * Added public key verification process into client's protocol.c.
8163 The client now verifies the public key from user and saves
8164 it into ~./silc/serverkeys/ directory.
8166 Added into: clientutil.[ch]: silc_client_verify_server_key.
8168 * Changed SKE protocol's silc_ske_initiator_finish function
8169 to accept callback function that verifies the received public
8170 key. Removed old silc_ske_verify_public_key function.
8172 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8174 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8175 silc_pkcs_private_key[_data]_set.
8177 * Made the password and public authentication more cleaner in
8178 server's protocol.c.
8180 * Removed historic and obsolete protocol `channel_auth' from
8181 both client and server.
8183 * Removed wrong way of sending command status messages from
8184 server to client in server's command.c. The old way violated
8185 protocol specification.
8187 Changes to silccore/silccommand.[ch]: removed
8188 silc_command_encode_status_payload -> not needed anymore,
8189 changed silc_command_encode_payload_va to accept extra
8190 argument on variable argument list. The argument type must
8191 now be provided to the function. Also, added new function:
8192 silc_command_encode_reply_payload_va which is same as
8193 normal command_encode_payload_va except command status type
8194 is provided as extra argument.
8196 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8198 * Added ~./silc directory handling. The directory includes the
8199 public and private keys for the client.
8201 Added silc_client_check_silc_dir, silc_client_create_identifier
8202 and silc_client_load_keys.
8204 * Implemented SILC protocol compliant public key. Added public
8205 and private key saving to and loading from files.
8207 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8208 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8209 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8210 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8211 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8213 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8214 silc_pkcs_load_[public/private]_key.
8216 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8218 * Added silc_server_get_route (route.[ch]) to get connection
8219 data for the fastest route for given ID.
8221 * Implemented INVITE command on client and server. The command
8222 were re-defined in the SILC Protocol Specification and the
8223 implementation now complies with the specification.
8225 * Implemented PING command on client and server.
8227 * Implemented NAMES command on client and server. The server side
8228 supports currently only normal server not router server yet.
8229 Some changes to NAMES definition in SILC protocol specification.
8231 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8233 * Implemented LEAVE command on client and server.
8235 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8236 again. This change was made to the protocol as well. Server
8237 should not violate the protocol specification anymore.
8239 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8241 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8242 was tested. SOCKS4 was not but should work anyway.
