1 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Changed all library interfaces that use Global RNG to also
4 accept SilcRng as argument. Affected files are
5 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
6 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
7 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
8 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
11 * Added function silc_pkcs_generate_key to the
12 lib/silccrypt/silcpkcs.[ch] for applications so that they
13 don't need to do pkcs->pkcs->init calls anymore.
15 * Remove SilcSocketConnection from the SFTP API since it really
16 wasn't needed there. The application has the information
17 saved in its contexts anyway and the SFTP layer doesn't need
18 know about it. Affected files lib/silcsft/silcsftp.h and
19 lib/silcsftp/sftp_[server/client].c.
21 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
22 The SilcSimContext is not SilcSim.
24 * Fixed possible buffer overflows in silc_id_render in the
25 lib/silcutil/silcutil.c.
27 * On EPOC the global crypto module lists are not used at all
28 in the crypto library. Added support for using the constant
29 algorithm list on EPOC. Affected files are
30 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
33 * Fixed the handling of third parameter of KICKED notify, since
34 it was mistakenly updated to SILC Protocol 1.0 even though it
35 is to be included in 1.1. Since it is not in 1.0 it is not
36 mandatory, and this fix now handles it only if it is provided,
37 and it is not error if it is not provided. Affected file
38 lib/silcclient/client_notify.c.
40 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
42 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
43 client. Affected file irssi/src/silc/core/client_ops.c.

50 sending any messages. Fixes a crash, but doesn't fix some
51 other underlaying bug that is lurking there. Affected
52 file silcd/packet_send.c.
54 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
56 * $usermode, $cumode and $cumode_space expandos shouldn't do
57 anything with non-SILC server records. Affected file
58 irssi/src/silc/core/silc-expandos.c
60 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
62 * Fixed the silc_net_check_[host/local]_by_sock to support
63 IPv6 bound sockets as well. Now they can return IPv6 addresses
64 as well. Affected file lib/silcutil/silcnet.c.
66 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
67 Affected lib/silcutil/unix/silcunixnet.c.
69 * Fixed ID rendering (at least on some platforms, not NetBSD)
70 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
72 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
74 * Added silc_hash_public_key and silc_hash_public_key_compare
75 functions to be used with SilcHashTable. They can be used to
76 hash public keys and compare public keys in hash table. Affected
77 file lib/silcutil/silcutil.[ch].
79 * Added support for specifying multiple public keys for Client
80 connection section in server configuration file. This makes it
81 possible to accept multiple public keys from same host, or to
82 make a section that accepts any incoming host, and have the
83 accepted public keys listed in the section.
85 Added functions silc_sever_[find/get]_public_key, added the
86 support for this actually to all connection sections but only
87 the Client section is currently allowed to specify multiple
90 Affected files are silcd/server.c, server_internal.h,
91 command.c, protocol.c, server_util.[ch], packet_receive.c.
93 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
95 * Merged Irssi 0.8.2 from irssi.org CVS.
97 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
99 * If silc_debug is TRUE, also output standard logging messages
100 to stderr with the debug output.
102 Made silc_log_reset_all() flushing all channels before returning.
103 Also fixed some documentation typos.
105 Affected files are lib/silcutil/silclog.[ch].
107 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
109 * Fixed the server to check correctly the amount of connections
110 from single host, by checking also the type of the connection.
111 Fixed also the comparison of number of connections and number
112 of allowed connections. Affected files are silcd/server.c,
115 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
117 * Fixed the USERS command reply to save the user's mode on the
118 channel as well. Fixed JOIN command reply to check whether a
119 client is on channel already and not join it twice. Affected
120 file lib/silcclient/command_reply.c.
122 * Added new file silc-expandos.c into irssi/silc/core/ to return
123 various stuff for various signal for the statusbar etc. updating.
124 Now Irssi SILC client prints channel user modes etc. on the
127 * The user mode (like server/router operator changes) is now shown
128 on the Irssi SILC client's statusbar. The affected files are
129 irssi/src/silc/core/client_ops.c, silc-expandos.c.
131 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>

145 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
147 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
148 constants. Affected files in
149 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
152 * Changed the internal SFTP Memory FS table to const. Affected

165 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
167 * Changed all integer type names:
168 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
169 to avoid collisions with other libraries using same type names
172 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
174 * Added `prefer_ipv6' argument to the functions
175 silc_net_gethostbyname[_async]. If it is TRUE it will return
176 IPv6 address over IPv4. If FALSE IPv4 address is returned
177 even if IPv6 address was found. Affected files
178 lib/silcutil/silcnet.[ch].
180 * Added support silc_net_create_connection[_async] to fallback
181 to IPv4 address if IPv6 address could not be used (like if
182 it doesn't work on a specific system). Affected file in

194 application does not need to define them. Affected file
195 includes/silcincludes.h.
197 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
198 old name went against naming convention. Applications now
199 include "silcclient.h" instead of "clientlibincludes.h".
200 Removed includes/clientlibincludes.h, it is redundant now.
202 * Renamed includes/version.h to silcversion.h.
204 * Added really preliminary support for OS/2 into the util
205 library. Only thread & mutex API is implemented, others
206 are still to be implemented. Created the lib/silcutil/os2/
207 directory. Created also file includes/silcos2.h.
209 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
211 * Added preliminary BeOS support into the util library.
212 Created lib/silcutil/beos/, and implemented all the needed
213 functions to support SILC on BeOS. Created also file

218 * Added proper initializations to silc's irssi code, so it's
219 now possible to load it as module. Affected files
220 irssi/src/silc/core/silc-core.c,
221 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
223 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>

238 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
240 * Added `user_count' to the SilcChannelEntry which now tells the
241 number of users on the channel. The user count is now saved
242 in normal server of global channels as well. Affected files
243 silcd/server.c, idlist.h, packet_receive.c and command.c.
245 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
246 include file utility functions.

256 client_entry->channels hash table everytime nick is changed.
257 Affected file lib/silcclient/client.c.
259 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
261 * ROBOdoc documented the lib/silcske/silcske.h, and improved
262 the SKE interface a bit.
264 * Fixed padding problem in PKCS#1. The padding was not actually
265 random since the random number generator was used incorrectly.
266 This security bug affects only when encrypting with PKCS#1, and
267 it is not currently used at all in SILC. SILC only use signing
268 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
270 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
272 * Rewrote the notify handling in Irssi SILC client to not call

287 Optimized the use of SKE Mutual flag usage. Use it only
288 if connection authentication protocol is not based in public
291 Renamed all SilcServerConfigSection* to SilcServerConfig*
292 to have a bit shorter names.
294 Affected files silcd/serverconfig.[ch], server.[ch], and
297 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

312 * Fixes to the silcd config template. Affected file is
313 doc/example_silcd.conf.in.
315 * Removed type casts from silc_calloc(), conforming to the
316 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
318 * Removed param_name member from client, server, and router
319 section structs, now identifying the param directly.
321 Added CONFIG_FREE_AUTH macro in config file parsing.
323 Affected files are silcd/serverconfig.[ch].
325 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>

328 is now done in silc_core_init() which also fixes autoconnecting
331 Affected files irssi/src/silc/core/silc-core.c,
332 irssi/src/fe-text/silc.c.
334 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
336 * Added new configuration options and blocks:
337 keepalive_secs, reconnect_count, reconnect_interval,
338 reconnect_interval_max, reconnect_keep_trying and
339 require_reverser_lookup. Added ConnectionParam block, and
340 implemented the connection parameters when connecting as
341 initiator and when accepting connections as responder.
343 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
344 whether given configuration value has been given already.
346 Affected files silcd/serverconfig.[c], server.[c].
348 * Splitted the doc/example_silcd.conf.in. Separated the crypto
349 algorithm parts and created new file silcalgs.conf, that
350 is now included from the example_silcd.conf.in.
352 * Optimized the silc_server_connect_to_router_second to take
353 the connection configuration object from the SilcServerConnection
354 object instead of finding it during the connecting phase.
355 Added the configuration object to SilcServerConnection struct.
356 Affected files silcd/server_internal.h, server.c.
358 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
360 * Add the client on channel after it was resolved at the
361 channel message receiving, and it was not already on the
362 channel. Affected file lib/silcclient/client_channel.c.
364 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
366 * Fixed the public key authentication to allocate always the
367 destination signature buffer instead of using static buffer.
368 Affected file silcd/protocol.c.
370 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
372 * Unified the serverconfig.[ch]'s helper function interface.
373 Affected file silcd/serverconfig.[ch].
375 * Removed doc/example_silc.conf.in since it is redundant.
376 The make install will now install irssi/silc.conf file.
378 * Added new Passphrase and Publickey authentication methods to
379 config file, allowing both public key and passphrase based
380 authentication to be set at the same time.
382 Added `prefer_passphrase_auth' setting in config file which
383 can be used to set to prefer passwd auth if both passwd and
384 public key is set. If not set, public key is preferred.
385 This has effect only when being initiator (responder will try
388 Added support for authentication with passphrase and public key
389 at the same time. The passphrase is tried first always since
390 it is faster to check.
392 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
394 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

438 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
440 * Fixed the file transfer's key agreement payload to include
441 zero port also if the hostname is NULL because it could not
444 Call file transfer monitor callback now also if error occurs
445 during key agreement protocol.
447 Changed the silc_client_file_send interface to return the
448 SilcClientFileError instead of session id. The session ID
449 is returned into pointer provided as argument.
451 Check that the file exists locally before sending the
452 file transfer request at all.
454 Affected file lib/silcclient/client_ftp.c, silcapi.h.
456 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
457 error than can occur while key agreement protocol. Affected
458 file lib/silcclient/silcapi.h.

462 irssi/src/silc/core/silc-channels.c.
464 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
465 SILC_LOG_WARNING to give out Warning and not Error. Affected
466 file lib/silcutil/silclog.c.
468 * Fixed the channel message payload decryption in the function
469 silc_channel_message_payload_decrypt to not modify the original
470 buffer before it is verified that the message decrypted
471 correctly. Otherwise, next time it is called with correct
472 channel key it won't encrypt since the payload is corrupted.
473 Affected file lib/silccore/silcchannel.c.
475 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

487 * Fixed a bug in hash table internal routine for traversing
488 the table with foreach callback. The current entry may
489 become invalid in the callback but it was referenced after
490 the callback returned.
492 Do not allow auto rehashing of hash table during the
493 silc_hash_table_foreach operation, for same reasons as it is
494 not allowed for SilcHashTableList. Affected files are
495 lib/silcutil/silchashtable.[ch].
497 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
499 * Defined DLLAPI into silcincludes.h and silcwin32.h for

503 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
505 * Fixed private message handling. It used some old code that
506 caused the client to crash. Affecte file is
507 lib/silcclient/client_prvmsg.c.
509 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
511 * Added function silc_client_add_channel,
512 silc_client_replace_channel_id, and removed functions
513 silc_client_new_channel_id and silc_idlist_get_channel_by_id
516 * Added cross reference of the joined channels to the
517 SilcClientEntry, and changed the SilcChannelEntry's
518 users list to SilcHashTable. The affected files are
519 lib/silcclient/idlist.[ch].
521 * Fixed a bug in hash table tarversing. While the hash table
522 is traversed with SilcHashTableList the table must not be
523 rehashed. It is now guaranteed that auto rehashable tables
524 are not rehashed while tarversing the list. Also defined that
525 silc_hash_table_rehash must not be called while tarversing
526 the table. Added function silc_hash_table_list_reset that must
527 be called after the tarversing is over. The affected files are
528 lib/silcutil/silchashtable.[ch].
530 * Changed all hash table traversing to call the new
531 silc_hash_table_list_reset in server and in client library.
533 * Added function silc_client_on_channel to return the
534 SilcChannelUser entry if the specified client entry is joined
535 on the specified channel. This is exported to application as
536 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
538 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
540 * Fixed founder regaining problem with JOIN command on normal
541 server. The notify for mode change must be sent always and
542 not only if !cmd->pending. Affected file silcd/command.c.
544 * Fixed the WHOWAS command's reply sending to support the
545 lists correctly. Affected file silcd/command.c.
547 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
549 * When sending JOIN command to router for processing the
550 sender's old command identifier was not saved back to the
551 sender's command context, fixed now. The affected file is
554 * Create the key in JOIN command of the router did not return
555 the channel key, added check for this. Affected file is
558 * Fixed a channel ID update bug in JOIN command reply. Do
559 not directly upgrade the ID but call the function
560 silc_idlist_replace_channel_id if the ID was changed.
561 Affected file silcd/command_reply.c.
563 * Fixed memory leaks from command calling if it would fail.
564 Affected file silcd/command.c.
566 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
568 * Applied patches from cras:
570 Memory leak fixes around libaries, irssi window resize fix,
571 new silclist.h and silcdlist.h, all extern inline changed to
574 * Removed dotconf from lib/dotconf, not needed anymore.
576 * Removed TRQ from lib/trq, not needed anymore.
578 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
579 with server connections. Later this will be configurable
580 in config file after new config file is done. Affected file
583 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
585 * Fixed a crash in server related to channel announcements.
586 Affected file silcd/server.c.
588 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
590 * Fixed memory leaks in silc_server_create_new_channel*
591 functions. Affected file silcd/server.c.
593 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
594 which ID was changed. This way the router will send the
595 user list for the channel again, and server won't be in
596 desync in some rare circumstances. Affected file is
597 silcd/packet_receive.c.
599 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
601 * Check for NULL socket pointer in the function
602 silc_server_packet_send_to_channel_real. Affected file
605 * Fixed the BAN notify handling to correctly remove ban
606 list. Affected file silcd/packet_receive.c.
608 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
610 * Fixed some header addition to Toolkit distribution in
611 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
613 * Added lib/silcclient/client_ops_example.h as an template
614 file for application programmers to quickly start using
615 the SilcClientOperation functions in their application.
616 Updated the lib/silcclient/README as well to tell about this
617 nice file made available.
619 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
621 * Call silc_server_remove_from_channels when removing client
622 entry when NO_SUCH_CLIENT_ID was received. Affected file
623 is silcd/command_reply.c.
625 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
627 * Added server & router operator statistics updating. Affected
628 file silcd/packet_receive.c and silcd/command.c.
630 * Fixed the SERVER_SIGNOFF notify handling on normal server
631 not to save the history information for clients. Same was
632 fixed earlier in remove_clients_by_server function, but not
633 here. Affected file silcd/packet_receive.c.
635 * Raised the default connection-retry count from 4 to 7 in
636 server. Affected file silcd/server.h.
638 * Cancel any possible reconnect timeouts when we start the
639 key exchange. Affected file silcd/server.c.
641 * Do not reconnect on connection failure when SCONNECT was
642 given. Affected files silcd/server.[ch].
644 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
646 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
648 * Fixed the NICK command to always give the unformatted
649 nickname to the one giving the NICK command. If unformatted
650 nickname is cached already it will be formatted and the
651 local entry will always get the unformatted nickname.
652 Affected file lib/silcclient/idlist.c.
654 * Fixed some double frees from client library commands.
655 Affected file is lib/silcclient/command.c.
657 * Fixed CUMODE command in server to assure that no one can
658 change founder's mode than the founder itself, there was a
659 little bug. Affected file silcd/command.c.
661 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
663 * Removed the SilcClientCommandDestructor from the client
664 libary, it is not needed anymore. Affected files are
665 lib/silcclient/silcapi.h, command[_reply].[ch],
666 client_notify, idlist.c.
668 * Fixed GETKEY command to first resolve client, and then
669 resolve the server only if the client was not found, instead
670 of resolving both at the same time. Affected file is
671 lib/silcclient/command.c.
673 * Added silc_client_start_key_exchange_cb and lookup the
674 remote hostname and IP address before starting the key
675 exchange with server. The affected file is
676 lib/silcclient/client.c.
678 * The server's public key is now saved using the IP address
679 of the server and not the servername for the filename.
680 The hostname public key filename is checked as an fall back
681 method if the IP address based filename is not found.
683 Fixed the GETKEY command to save the fetched server key
686 Print the remote server's hostname now when new key is
687 received during connection process. Affected file is
688 irssi/src/silc/core/client_ops.c.
690 * Return always our own public key to the client if it asks
691 for it with GETKEY command. Affected file silcd/command.c.
693 * Removed the use_auto_addr variable from default config
694 file since it was in wrong section. Affected file is
697 * Fixed TOPIC_CHANGE notification to not route it when it
698 was sent using silc_server_send_notify_to_channel function.
699 Affected file silcd/command.c.
701 * Fixed silc_server_send_notify_kicked to send the kicker's
702 Client ID also, it was missing. Affected files are
703 silcd/command.c, silcd/packet_send.[ch].
705 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
707 * Do not save client history information in SERVER_SIGNOFF.
708 Fixes the bug in normal server that it does not detect
709 the client becoming valid after the server becomes back
710 online. Affected file silcd/server_util.c.
712 * Added `sock_error' field into the SilcSocketConnection
713 context. When error occurs during socket operation (read
714 or write) the error is saved. Added also new function
715 silc_socket_get_error to return human readable socket error
716 message. Affected files are lib/silcutil/silcsockconn.[ch],
717 lib/silcutil/unix/silcunixsockconn.c, and
718 lib/silcutil/win32/silcwin32sockconn.c.
720 * The server now prints the socket error message in the
721 signoff for client. Affected file silcd/server.c.
723 * Fixed the `created' channel information sending from router
724 to server in JOIN command. Checks now whether the channel
725 really was created or not and set it according that.
727 Fixed the JOIN command to use the client entry's current
728 ID during the joining procedure instead of the one it sent
729 in the command (it is checked though), since it can change
730 between the packet processing and command processing, and
731 would just case unnecessary pain in the client end. Affected
732 file silcd/command.c.
734 * Fixed a channel key payload sending to use correct channel
735 ID when the server was forced to change the channel's ID by
736 router. Router sent the key payload with the old Channel ID.
737 Affected file silcd/packet_receive.c.
739 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
741 * Call silc_server_save_channel_key only if the key payload
742 was provided in the JOIN command's command reply. Affected
743 file silcd/command_reply.c.
745 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
747 * Fixed silc_mp_sizeinbase to return the value correctly with
748 MPI. Affected file lib/silcmath/mp_mpi.c.
750 * Fixed the stop_server signal to correctly stop the scheduler
751 and gracefully stop the server when SIGTERM or SIGINT signals
752 are received. Affected file silcd/silcd.c.
754 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
756 * Simple handling of TERM and HUP signals. Also added some log
757 flushing call around. Affected file is
760 * Fixed small bugs in silclog.c. Now buffering output will take
761 effect after 10 seconds since startup: This will ensure that
762 no important startup messages are lost. Also output redirection
763 will preserve original format ([Date] [Type] message).
764 Affected file is lib/silcutil/silclog.c.
766 * Added two options to the config file, in the logging section:
767 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
768 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
770 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
772 * Do not print the warning about log files not being initialized
773 more than once to avoid excess logging. Affected file is
774 lib/silcutil/silclog.c.
776 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
777 the SIM copying in make install in Makefile.am.pre.
779 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
781 * Rewritten silclog APIs. Globally interesting changes follows:
782 silc_log_set_files() changed to silc_log_set_file().
783 silc_log_set_callbacks() changed to silc_log_set_callback().
784 ROBOdoc documented silclog header file.
785 SilcLogCb now returns bool to wether inihibit the default
786 handler or not (to keep the old behaviour return always TRUE).
787 The new APIs should also fix the problem of the
788 silcd_error.log file that was written in the current directory.
791 Log files streams will remain opened after silc_log_set_file()
792 call, means less CPU usage notably on high traffic servers.
793 File streams are now full buffered, and flushed to the disk
794 every 5 minutes, lesses HD activity and CPU usage.
795 Messages can be redirected, allowing admins to configure
796 one single logfile for all server messages.
797 the silc_log_quick global variable to activate fast-logging.
798 Affected files lib/silcutil/silclog.[ch]
800 * Changed some code to conform new silclog APIs. Affected
801 files are doc/example_silcd.conf.in, silcd/server.c
802 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
805 * Fixed a memory leak that could occur in some situations.
806 Affected file silcd/serverconfig.c.
808 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
810 * Added the silc_client_del_client to remove the client from
811 all channels as well. Affected file lib/silcclient/idlist.c.
813 * Fixed the client library to correctly remove the client
814 from all channels when the client entry is being destroyed.
815 Affected file lib/silcclient/client_notify.c, command.c.
817 * Added auto-nicking support to the client library. If the
818 applicatio now sets client->nickname it will be sent to the
819 server after connecting by the library. This way for example
820 SILCNICK (or IRCNICK) environment variables will have effect
821 and always change the nickname automatically to whatever
822 it is wanted. Affected file lib/silcclient/client.[ch].
824 * Renamed silc_server_command_bad_chars to the
825 silc_server_name_bad_chars and moved it to the
826 silcd/server_util.[ch]. Added also new function
827 silc_server_name_modify_bad to return nickname that
828 includes bad characters as new nickname without those
829 bad characters. This check and modify is now used in
830 silc_server_new_client when the username is initially set
831 as nickname, so it must be checked to be valid nickname.
832 Affected file silcd/packet_receive.c.
834 * The nickname length is now taken from the packet for real
835 and not trusted to strlen() since it clearly can return
836 wrong length for nickname including bad characters. This
837 also applies to channel names. Affected file silcd/command.c.
839 * Removed the lib/silcsilm/modules directory. Modules are now
840 compiled into the lib/silcsim. Fixed the copying of the
841 modules to follow symbolic links in Makefile.am.pre.
843 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
845 * Fixed silc_string_regexify list creation. Fixes bugs with
846 BAN and INVITE commands in server. The affected file is
847 lib/silcutil/unix/silcunixutil.c.
849 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
851 * Removed the command destructor entirely from the server's
852 command and command reply routines. It is not needed, and
853 its usage was buggy and caused crashes. Affected files are
854 silcd/command[_reply].[ch].
856 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
858 * Cancel protocol and NULL sock->protocol if timeout
859 occurred during protocol. Affected file silcd/server.c.
861 * Cancel protocol timeouts always before calling the final
862 callback, to assure that after final callback is called
863 no other state will be called for the protocol anymore.
864 Affected file silcd/protocol.c.
866 * Print error log if incoming connection configuration could
867 not be found. Affected file silcd/server.c.
869 * Fixed JOIN command to correctly save the founder mode
870 to the client on normal SILC server, when the channel
871 was created by the router. Affected file silcd/command.c.
873 * Fixed LIST command (hopefully) to send correct reply
874 packets. Affected file silcd/command.c.
876 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
878 * The silc_packet_receive_process now returns FALSE if the
879 read data was invalid packet, and TRUE if it was ok.
881 The server now checks that if unauthenticated connection
882 sends data and its processing fails the server will close
883 the connection since it could be a malicious flooder.
885 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
887 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
889 * Make sure the warning about error opening a log file is
890 printed only once and not everytime it fails (produces
891 too much useless log). Affected file lib/silcutil/silclog.c.
893 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
895 * Made the silc_server_daemonise() function more readable.
896 Affected file silcd/server.c.
898 * Pid file is now optional, the user may comment it out from
899 the config file. Removed define SILC_SERVER_PID_FILE, we
900 don't need a default any longer. Affected file
901 configure.in.pre, lib/Makefile.am.pre.
903 * Make some use of the pid file. The server now dies at startup
904 if it detects a valid pid file on his path. The server would
905 die anyway in this circumstance, because of the bind() failure.
906 Affected file silcd/silcd.c.
908 * No longer compiling lib/dotconf.
910 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
912 * Fixed JOIN command parsing not to crash. Affected file
913 lib/silcclient/command.c.
915 * Fied the NICK_CHANGE notify to add the new client entry
916 even it is resolved. This removes an <[unknown]> nick
917 thingy bug in the client. Affected file is
918 lib/silcclient/client_notify.c.
920 * Do not try to allocate 0 bytes (efence does not like it)
921 in lib/silccore/silccomand.c when encoding payload.
923 * Do not take IRCNICK as nickname in Irssi SILC client since
924 it is not possible to set nickname before hand connecting
925 the server (TODO has an entry about adding auto-nicking
928 * Changed the silc_server_command_pending to check whether
929 there already exists an pending entry with the specified
930 command, command identifier and pending callback. This is
931 to fix IDENTIFY and WHOIS related crashes that may register
932 multiple pending commands with same identifier. Affected
933 file silcd/command.c.
935 * Fixed the server to reconnect to the router even if it
936 was already reconnecting and EOF was received. This to
937 fix a possibility that the server wouldn't ever try to
938 auto-reconnect to the router. Affected file silcd/server.c.
940 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
942 * Fixed the server's password authentication to use the
943 length of the locally saved password, and not the one
944 sent in the packet. Affected file silcd/protocol.c.
946 * Fixed same password authentication problem in the
947 Authentication Payload handling routines in
948 lib/silccore/silcauth.c.
950 * Yet another password authentication problem fixed with
951 channel password handling in silcd/command.c.
953 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
955 * If first character of string in silc_parse_userfqdn is '@'
956 then do not parse it. Affected file is
957 lib/silcutil/silcutil.c.
959 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Fixed minor bug in IDENTIFY command reply sending, which
962 caused various weird problems during JOIN when it was
963 resolving names for users. Affected file silcd/command.c.
965 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
967 * Fixed the IDENTIFY command reply sending to chech better valid
968 clients. It was possible to send incomplete list of replies.
969 Affected file silcd/command.c.
971 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
973 * Added silc_client_command[s]_[un]register functions now to
974 dynamically register the commands in client library. Removed
975 the static table of commands. This allows the client library
976 to call commands without causing the application to know about
977 what commands library has called.
979 Removed the INFO command reply kludge to detect when the command
980 was called by library. Now library use its own command reply
981 function for INFO command.
983 Added function silc_client_command_call to call a command.
984 Application can use it to call command, not access the structure
987 Now all commands that are sent by the client library (not
988 explicitly sent by application) use own command reply functions.
990 Affected files around lib/silcclient/ and in
991 irssi/src/silc/core/.
993 * Fixed the WHOIS command reply sending to chech better valid
994 clients. It was possible to send incomplete list of replies.
996 Fixed the WHOIS and IDENTIFY to send the request to router
997 if normal server did not do it and did not find any results.
999 Affected file silcd/command.c.
1001 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1003 * Moved the internal data from SilcClient context into its
1004 own file, not accesible to application. Affected files
1005 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1006 and other files in client library.
1008 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1010 * Added doc/examples installation target in Makefile.am.pre.
1013 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1015 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1016 commands the found client entry will be removed from the
1017 cache, after notifying application about the error. Affected
1018 file lib/silcclient/command_reply.c.
1020 * Changed the /MSG to check for exact nickname user gave, and
1021 not let `nick' match `nick@host' if it is only one found. Now,
1022 user must type the exact nickname (like nick@host2) even if
1023 there are no more than one same nicks found. This is to avoid
1024 a possibility of sending nickname to wrong nickname since
1025 `nick' could match `nick@host'. Affected file is
1026 irssi/src/core/silc-servers.c.
1028 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1030 * Do not print "you are now server operator" or similar when
1031 giving /away command. Affected files are
1032 irssi/src/silc/core/client_ops.c, silc-servers.h.
1034 * Made the silc_server_command_pending_error_check to send
1035 the same command reply payload it received back to the
1036 original sender of the command. This way all arguments
1037 that was received by the server will be received by the
1038 client too. Affected file silcd/command.c.
1040 * Added the silc_idcache_add to return the created cache entry
1041 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1043 * Add global clients to expire if they are not on any channel.
1044 This is because normal server will never know if they signoff
1045 if they are not on any channel. The cache expiry will take
1046 case of these entries. This is done by normal servers only.
1047 The affected files are silcd/command_reply.c,
1048 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1050 * If server receives invalid ID notification for WHOIS or
1051 IDENTIFY and the ID exists in the lists, it is removed.
1052 Affected file silcd/command_reply.c.
1054 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1055 in client then client entry that it matches is searched and
1056 the nickname is printed on the screen for user. Affected
1057 file irssi/src/silc/core/client_ops.c.
1059 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1061 * Use cache entry expire time in the LIST command reply to
1062 purge old entries from the cache after the LIST command
1063 reply has been received. This way we don't have non-existent
1064 entries in the cache for too long. Affected file is
1065 silcd/command_reply.c.
1067 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1069 * If we are normal server, and we've not resolved client info
1070 in WHOIS or IDENTIFY from router, and it is global client,
1071 we'll check whether it is on some channel. If it is not
1072 then we cannot be sure about its validity and will resolve it
1073 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1074 file silcd/command.c.
1076 * Search channel by name (if possible) rather than by ID
1077 in IDENTIFY command's command reply. Affected file is
1078 silcd/command_reply.c.
1080 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1082 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1083 Updated specs and implemented it. Affected file silcd/command.c,
1084 silcd/packet_send.c and silcd/packet_receive.c.
1086 * Implemented the <founder auth> payload handling in the JOIN
1087 command. If provided all conditions for channel joining
1088 except requirement to provide correct passphrase can be
1089 overrided by the channel founder. Updated the protocol specs.
1090 Affected file silcd/command.c.
1092 Added support for founder auth in JOIN command in client
1093 library. Fixed the parsing of the JOIN command now to support
1094 all options as they should be. The affected file is
1095 lib/silcclient/command.c.
1097 * Optimized the WHOIS and IDENTIFY commands to send the request
1098 to router only if it includes nicknames or other names. If
1099 they include only IDs then check the local cache first before
1100 routing. Affected file is silcd/command.c.
1102 * Added channels topic announcements. Affected file is
1103 silcd/packet_receive.c and silcd/server.c.
1105 * Fixed the silc_server_send_notify_topic_set to really destine
1106 the packet to channel. Affected file silcd/packet_send.c.
1108 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1109 library. Affected file lib/silcclient/client_notify.c.

1128 * ROBOdoc documented the lib/silcske/groups.h file and a
1129 bit changed the interface for better.
1131 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1133 * Update the client entry context in the ID cache after
1134 nick change. Affected file lib/silcclient/command.c.
1135 Fixes the CUMODE command when regaining founder privileges,
1136 and a little WHOIS problem.
1138 * Fixed silc_net_gethostbyname to correctly call the
1139 inet_ntop. Affected file lib/silcutil/silcnet.c.
1141 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1143 * Added IPv6 support checking to the configure.in.pre, added
1144 also --enable-ipv6 option to override the check. Affected
1145 file configure.in.pre.
1147 * The silc_thread_create now calls the start function
1148 directly if threads support is not compiled in. Removes
1149 ugly #ifdef's from generic code. Affected files are
1150 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1152 * Added silc_net_gethostby[name/addr]_async to asynchronously

1164 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1165 routines. Added silc_net_is_ip[4/6]. Affected file is
1166 lib/silcutil/unix/silcunixnet.c. All routines that take
1167 address as argument now supports both IPv4 and IPv6 addresses.
1169 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1171 * Fixed LIST command reply sending in server. Affected file
1174 * Server now sends the kicker's client ID in the KICK notify
1175 to the kicked client. Affected file silcd/command.c.
1177 * The client library now parses the kickers client ID and
1178 UI displays it. Affected files lib/silcclient/client_notify.c
1179 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1181 * Made all payload parsing function prototypes consistent.
1182 They all take now const unsigned char * and uint32 pair as
1183 the payload data instead of SilcBuffer. Changes all around
1184 the source tree. Other unsigned char* -> const unsigned char*
1185 changes around the tree as well.
1187 * Optimized SFTP client and server packet sending not to
1188 allocate new buffer for each packet but to recycle the
1189 first allocated buffer. Affected files are
1190 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1192 * Optimized the SFTP client to use SilcList instead of
1193 SilcDList for requests, because it is faster. Affected file
1194 is lib/silcsftp/sftp_client.c.
1196 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1197 into lib/silccore/silcid.[ch].
1199 Renamed silcpayload.[ch] into silcargument.[ch].
1201 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * If client entry is deleted with active key agreement
1204 session, abort the session.
1206 The silc_client_abort_key_agreement now calls the completion
1207 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1209 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1212 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1214 * Don't use __restrict in older GCC's. Affected file is
1215 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1217 * silc_net_localhost now attempts to reverse lookup the
1218 IP/hostname. Affected file lib/silcutil/silcnet.c.
1220 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1221 command. It can be used to gain founder privileges at
1222 the same time when joining the channel.
1224 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1225 kicker's client ID as well. Updated protocol specs.
1227 Defined that the server must send SILC_COMMAND_IDENTIFY
1228 command reply with error status to client who sent
1229 private message with invalid client ID.
1231 Updated the protocol specification.
1233 * Added silc_server_send_command_reply to send any
1234 command reply. Affected file silcd/packet_send.[ch].
1236 * Added silc_id_payload_encode_data to encode ID payload
1237 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1239 * The server now send IDENTIFY command reply with error
1240 status if client ID in private message is invalid. Affected
1241 file silcd/packet_receive.c.
1243 * Save the server key file with server's IP address in
1244 the filename instead of hostname. The affected file is
1245 irssi/src/silc/core/client_ops.c.
1247 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1249 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1252 * Added libtool support for compiling shared objects in
1253 lib/silcsim. Affected file configure.in.pre and
1254 lib/silcsim/Makefile.am. Original patch by cras.
1256 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1258 * Pid file configuration, and server's config file fixes
1259 patch by toma. Updated CREDITS file.
1261 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Fixed silc_client_channel_message to not try to decrypt
1264 the message twice if it resolved the destination client
1265 information. This could cause of dropping one channel
1266 message. Affected file lib/silcclient/client_channel.c.
1268 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1270 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1271 lib/silcclient/client.c. This function is used when the SILC
1272 Client is run under some other scheduler, or event loop or
1273 main loop. On GUI applications, for example this may be
1274 desired to used to run the client under the GUI application's
1275 main loop. Typically the GUI application would register an
1276 idle task that calls this function multiple times in a second
1277 to quickly process the SILC specific data.
1279 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1281 * Fixed silc_server_drop() for dropping the supplementary
1282 groups as well, this could cause a security hole on some
1285 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1287 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1290 * Write PID file after dropping privileges. Added -F option
1291 to run server on foreground. A patch by debolaz.
1292 Affected files silcd/server.c, silcd/silcd.c.
1294 * Fixed MOTD to return the MOTD file server name. Affected
1295 file silcd/command.c.
1297 * Added INFO command reply handling to the Irssi SILC Client.
1298 Affected file irssi/src/silc/core/client_ops.c.
1300 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1302 * Fixed the silc_idcache_list_* routines to really support
1303 the dynamic list. Fixes a crash. Affected file is
1304 lib/silccore/silcidcache.c.
1306 * Fixed the LIST command reply to really call LIST command's
1307 pending callbacks. Affected file silcd/command_reply.c.
1309 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1311 * Update conn->local_entry->nickname after giving NICK
1312 command. Affected file lib/silcclient/command.c.
1314 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1316 * Added the [pid] option to the silcd configuration file
1318 Affected files: serverconfig.[ch] and silcd.c
1320 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1322 * Save fingerprint in WHOIS command reply in server.
1323 Affected file silcd/command_reply.c.
1325 * Fixed NICK commands pending callback registration.
1326 Affected file lib/silcclient/command.c.
1328 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1330 * Use ++server->cmd_ident when sending commands in server,
1331 instead of random number. Affected file silcd/command.c.
1333 * Fixed GETKEY command reply to call actually GETKEY pending
1334 command callbacks. Affected file silcd/command_reply.c.
1336 * A bit stricter check for nicknames. Check for same nickname
1337 in NICK command also. Affected file silcd/command.c.
1339 * Do not call INFO command everytime client ID changes, only
1340 during first connecting. Affected file lib/silcclient/client.c.
1342 * Set the new nickname only after successful command reply for
1343 NICK command is returned by server. Affected file
1344 lib/silcclient/command.c.
1346 * Remove nicknames from nicklist during server_signoff notify.
1347 Should fix /NAMES bit more. The affected file is
1348 irssi/src/silc/core/silc-channels.c.
1350 * Added `fingerprint' field to the SilcIDListData in the
1351 silcd/idlist.h to hold the fingerprint of the client's
1354 Send the fingerprint of the client's public key in WHOIS
1357 Affected files silcd/command.c, and silcd/idlist.[ch].
1359 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1360 create fingerprint from given data.
1362 * Show the fingerprint of the client's public key in WHOIS.
1363 Affected files irssi/src/module-formats.[ch] and
1364 irssi/src/silc/core/client_ops.c.
1366 * Format the multiple same nicknames also during JOIN and
1367 NICK_CHANGE notifys. Affected file is
1368 lib/silcclient/client_notify.c.
1370 * Do not print error on screen for invalid private message
1371 payload since it can come if someone is sending private
1372 messages with wrong key. Affected file
1373 lib/silccore/silcprivate.c.
1375 * Fixed multiple concurrent /PING crash. Affected file
1376 lib/silcclient/command.c.
1378 * Changed the wrong ID encoding. All IP addresses must be
1379 in MSB first order in encoded format. They were encoded
1380 wrong and was in LSB format. Affected files are
1381 silcd/serverid.c, lib/silcutil/silcutil.c.
1383 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1385 * Call the `connect' client operation through the scheduler
1386 in case of error. Affected file lib/silcclient/client.c.
1388 * Call the `failure' client operation even if the error
1389 occurred locally during a protocol. Affected file is
1390 lib/silcclient/protocol.c.
1392 * Added support of sending LIST command to router from normal
1393 server. This way normal server can get list of all channels
1394 in the network too. Fixed the channel list sending in the
1395 server too. Affected files are silcd/command.c, and
1396 silcd/command_reply.[ch].
1398 * Added silc_server_update_channels_by_server and
1399 silc_server_remove_channels_by_server. They are used during
1400 disconnection of primary router and in backup router protocol.
1401 Affected file silcd/server_util.[ch], silcd/server.c and
1402 silcd/server_backup.c.
1404 * Fixed channel adding to global list in IDENTIFY command
1405 reply in server. Affected file silcd/command_reply.c.
1407 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * If the incoming packet type is REKEY or REKEY_DONE process
1410 that packet always synchronously. Fixes yet another MAC
1411 failed error on slow (dialup) connections. Affected file
1412 lib/silcclient/client.c and silcd/server.c.
1414 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * Call check_version SKE callback for initiator too. Affected
1417 file lib/silcske/silcske.c.
1419 * Implemented fix for security hole found in the SKE that was
1420 fixed in the specification few days back; the initiator's
1421 public key is now added to the HASH value computation.
1422 Added backwards support for the old way of doing it too, for
1423 old clients and old servers. Affected file is
1424 lib/silcske/silcske.c.
1426 * Enabled mutual authentication by default in SKE. If initiator
1427 is not providing mutual authentication the responder will
1428 force it. This will provide the proof of posession of the
1429 private key for responder. The affected files are
1430 lib/silcclient/protocol.c and silcd/protocol.c.
1432 * Do not cache anymore the server's public key during SKE.
1433 We do mutual authentication so the proof of posession of
1434 private key is done, and if the server is authenticated in
1435 conn auth protocol with public key we must have the public
1436 key already. Affected file silcd/protocol.c.
1438 * Added new global debug variable: silc_debug_hexdump. If
1439 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1440 file lib/silcutil/silclog.[ch].
1442 * Fixed compilation warning due to char * -> const char *.
1443 Affected files lib/silcutil/silcnet.h, and
1444 lib/silccore/silcauth.[ch].
1446 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * Fixed CMODE command when new channel key was created. If
1449 the creation failed the old key was removed. Next time giving
1450 same command would crash the server since the old key was
1451 freed already. Affected file silcd/command.c.
1453 * Fixed the silc_server_announce_get_channels to not crash
1454 on reconnect. Affected file silcd/server.c.
1456 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Added silc_log_set_debug_string function to set a regex
1459 string to match for debug output. Only the function names,
1460 or filenames matching the given debug string is actually
1461 printed. This way it is possible to filter out those debug
1462 strings that user is not interested in.
1464 Fixed a bug in silc_string_regexify.
1466 Affected files lib/silcutil/silclog.[ch], and
1467 lib/silcutil/unix/silcunixutil.c.
1469 * Changed the -d options in both server and Irssi SILC client
1470 to take the debug string as argument. Affected files
1471 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1473 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1475 * Added silc_hash_babbleprint to create a Bubble Babble
1476 Encoded fingerprint. The encoding is developed by Antti
1477 Huima (draft-huima-babble-01.txt), and it creates human
1478 readable strings out of binary data. Affected file
1479 lib/silccrypt/silchash.[ch].
1481 * Print the babble print now in addition of fingerprint as well
1482 in Irssi SILC client. Affected files are
1483 irssi/src/fe-common/silc/module-formats.[ch],
1484 irssi/src/fe-common/silc/core/client_ops.c.
1486 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1488 * Fixed a security problem found in SKE. The initiator's
1489 public key too is now added to the HASH hash value creation
1490 which is signed by the responder to create the SIGN value.
1491 This will prevent anyone in the middle to lie to the responder
1492 about the initiator's public key. If this is done now, the
1493 man in the middle will get caught. Updated the protocol
1496 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1498 * Better installation directory handling. Configure module
1499 paths and other paths automatically to example_silc* files
1500 in doc/. A patch by toma.
1502 * Fixed compiler warning from MPI library, and from SILC RNG.
1505 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1506 It can be configured with ./configure. A patch by toma.
1508 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1510 * Find correct make to use in prepare-clean. A patch by
1511 toma. Affected file prepare-clean.
1513 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1515 * Added irssi variables use_auto_addr, auto_bind_ip,
1516 auto_bind_port and auto_public_ip.
1518 * Changed the interface for silc_client_send_key_agreement
1519 in lib/silcclient/silcapi.h
1523 irssi/src/silc/core/silc-core.c
1525 lib/silcclient/silcapi.h
1526 irssi/src/silc/core/silc-channels.c
1527 lib/silcclient/client_keyagr.c
1530 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Added silc_pkcs_public_key_compare to compare two
1533 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1535 * Check that the client who set the founder mode on the
1536 channel is the same client that is giving the founder
1537 mode to itself. It is done by comparing the saved public
1538 key (it is saved even in the authentication is passphrase).
1539 Affected file silcd/command.c.
1541 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1543 * Do not process packet for disconnected socket connection.
1544 Affected file lib/silccore/silcpacket.c.
1546 * Process the DISCONNECT packet through scheduler in the
1547 client library. Affected file lib/silcclient/client.c.
1549 * Fixed the silc_client_packet_parse to not to increase
1550 the packet sequence number if the conn->sock and the
1551 current socket connection is not same. This can happen
1552 for example during key agreement when the conn includes
1553 multiple socket connections (listeners). Affected file
1554 lib/silcclient/client.c.
1556 * The sender of the file transfer request now provides also
1557 the pointer (listener) for the key exchange protocol. If
1558 the listener cannot be created then it sends empty key
1559 agreement and lets the receiver provide the listener.
1561 Added `local_ip' and `local_port' arguments to the
1562 silc_client_file_send. If they are provided they are used,
1563 if not then it will attempt to find local IP address, if
1564 not found or bind fails then the remote client will provide
1567 Affected files are lib/silcclient/client_ftp.c and
1568 lib/silcclient/silcapi.h.
1570 * Extended the FILE SEND command to support defining the
1571 local IP and port for key exchange listener. They are
1572 optional. Affected file irssi/src/silc/core/silc-servers.c.
1574 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1576 * Defined to WHOIS command reply the sending of fingerprint
1577 of the client's public key (if the proof of posession of the
1578 corresponding private key is verified by the server).
1579 Updated to the protocol specification.
1581 * Added support of receiving the client's public key's
1582 fingerprint in command reply in client library. Affected
1583 file is lib/silcclient/command_reply.c, and
1584 lib/silcclient/idlist.[ch].
1586 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1588 * Do not send over 128 chars long nickname to the server
1589 in NICK command. Affected file lib/silcclient/command.c.
1591 * Do not send over 256 chars long channel names to the server
1592 in JOIN command. Affected file lib/silcclient/command.c.
1594 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1596 * Assure that silc_server_close_connection cannot be called
1597 twice for same socket context. Affected file is
1600 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1602 * Send error message to application if opening file for
1603 writing during file transfer fails. Affected file is
1604 lib/silcclient/client_ftp.c.
1606 Remove all file transfer sessions for a client that we're
1607 removing from ID cache.
1609 Affected file is lib/silcclient/client_ftp.c.
1611 * Fixed silc_net_addr2bin to return correct address. Affected
1612 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1614 * Fixed file transfer session removing on signoff notify.
1615 Affected file irssi/src/silc/core/silc-servers.c.
1617 * Added the SilcClientFileError to be returned in the monitor
1618 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1619 Affected file lib/silcclient/silcapi.h.
1621 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Fixed a crash in silc_client_ftp_free_sessions and
1624 silc_client_ftp_session_free_client. Affected file
1625 lib/silcclient/client_ftp.c.
1627 * Added `disabled' field in the SilcChannelEntry in the server
1628 to indicate if the server entry is disabled. Affected file
1629 silcd/idlist.h, silcd/command[_reply].c.
1631 * SILC server adds now /var/run/silcd.pid everytime it is
1632 started. Affected file silcd/silcd.c.
1634 * Added silc_server_packet_send_clients to send a packet to
1635 the provided table of client entries. Affected file
1636 silcd/packet_send.[ch].
1638 * Fixed a crash in client resolving in client_prvmsg.c in
1639 client library. Affected file lib/silcclient/client_prvmsg.c.
1641 * Do not actually remove the client directly from ID cache
1642 during SERVER_SIGNOFF, but invalidate it. This way we
1643 preserve the WHOWAS info for the client. Affected file
1644 silcd/server_util.c.
1646 * Fixed SERVER_SIGNOFF notify handling in the server. The
1647 server is now able to process incoming SERVER_SIGNOFF notify
1648 for a server that it doesn't even know about. It will remove
1649 the clients provided in the notify. Affected file
1650 silcd/packet_receive.c.
1652 * Check for partial packet in data queue after every packet that
1653 was found from the queue. Return and wait for more data if
1654 there is partial data in queue. Affected file is
1655 lib/silccore/silcpacket.c.
1657 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Added SilcClietFileError enum to indicate error in
1660 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

1662 Affected files lib/silcclient/silcapi.h and
1663 lib/silcclient/client_ftp.c.
1665 * Check that newsize in silc_buffer_realloc is larger than
1666 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1668 * Added better monitor of file transfers. It now monitors
1669 key agreement protocol during the file transfer too. Added
1670 error reporting too. Affected files
1671 irssi/src/silc/core/silc-servers.c,
1672 irssi/src/fe-common/silc/module-formats.[ch].
1674 * Wrote a help file for FILE command.
1676 * Added silc_rng_global_get_byte_fast to get not-so-secure
1677 random data as fast as possible. Random data is read from
1678 /dev/urandom if available and from the SILC RNG if not
1679 available. It is used in padding generation. Affected file
1680 lib/silccrypt/silcrng.[ch].
1682 * All packets in client library are now processed synchronously.
1683 Optimized packet processing a lot. Affected file
1684 lib/silcclient/client.c.
1686 * All server connection packets are processing synchronously
1687 now in server, to optimize packet processing. Affected file
1690 * Include files are installed now only in Toolkit distribution
1691 if make install is given. Affected files: all Makefile.am's.
1693 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1695 * Assure that silc_client_notify_by_server_resolve does not
1696 resolve the client information multiple times. If it cannot
1697 be found by the first it cannot be found at all. Affected
1698 file lib/silcclient/client_notify.c.
1700 * Fixed WHOWAS command reply calling. Affected file
1701 lib/silcclient/command_reply.c.
1703 * Removed all references to silc_idlist_get_client from the
1704 Irssi SILC client since that call is internal call used by
1705 the library. The Irssi SILC client will use now client
1706 retrieval functions found in silcapi.h.
1708 * Fixed a bug in resolving nickname info before sending
1709 private message. It used freed memory. Affected file
1710 irssi/src/silc/core/silc-servers.c.
1712 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1714 * Assure my_channels statistics cannot go negative in server.
1715 Affected files silcd/server.c, silcd/server_util.c.
1717 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1731 * Added silc_net_localip to return local host's IP address.
1732 Affected file lib/silcutil/silcnet.[ch].
1734 * If key exchange or rekey protocol is active for a connection
1735 parse all packets syncronously since there might be packets
1736 in packet queue that we are not able to process without first
1737 processing packets before them. Affected file silcd/server,
1738 lib/silcclient/client.c.
1740 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1741 whether library should continue processing the packet.
1742 Affected file lib/silccore/silcpacket.h.
1744 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1773 lib/silcutil/silcutil.[ch].
1775 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1777 * Resolve the client info when received private message or
1778 channel message for a client which nickname we don't know.
1779 Affected files lib/silcclient/client_prvmsg.c and
1780 lib/silcclient/client_channel.c.
1782 * Do not crash in /KEY if client is not connected. Affected
1783 file irssi/src/silc/core/silc-channels.c.
1785 * Added SilcClientStatus field to the SilcClientEntry in the
1786 lib/silcclient/idlist.h.
1788 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1789 is incomplete and is being resolved, it won't be resolved
1792 Make sure also that USERS command reply does not resolve
1793 twice information. Affected file is
1794 lib/silcclient/command_reply.c.
1796 Make sure that silc_client_get_clients_by_list does not
1797 resolve twice same information.
1799 * Check for valid client->id in the silc_server_free_client_data.
1800 Affected file silcd/server.c.
1802 * Fixed /GETKEY nick@server not to crash if the server entry
1803 is not found. Affected file lib/silcclient/command.c.
1805 * Fixed the silc_server_check_cmode_rights to check the
1806 requested modes correctly. Affected file silcd/command.c.
1808 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1810 * Better checks for non-printable chars in nick added.
1811 Affected file silcd/command.c.
1813 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1815 * Call the silc_server_udpate_servers_by_server in the
1816 primary router that comes back online in the backup resuming
1817 protocol. Otherwise it routes packets wrong. Affected file
1818 silcd/server_util.[ch], silcd/server_backup.c.
1820 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1822 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1823 lib/silcutil/silcbuffmt.[ch].
1825 * Redefined the SILC packet header to include the padding
1826 length. Affected file lib/silccore/silcpacket.[ch].
1828 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1829 length for maximum padding up to 128 bytes). Affected
1830 file lib/silccore/silcpacket.h.
1832 * Removed all backwards support for old 0.5.x MAC thingies.
1833 The SILC packet header change makes it impossible to be
1834 backwards compatible.
1836 * Send the ENDING packet with timeout in the backup resuming
1837 protocol. This is to assure that all routers has connected
1838 to the primary router. Affected file silcd/server_backup.c.
1840 * Changed the RNG to take the first IV from random data. It
1841 used to take it from zero actually. Changed the RNG also
1842 to use /dev/urandom during session. /dev/random is used
1843 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1845 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1847 * Changed the SILC packet header to have the first two bytes
1848 (the packet length) encrypted. Affected files aroung the
1849 code tree, lib/silccore/silcpacket.[ch]. Removed the
1850 SilcPacketCheckDecrypt callback. It is not needed anymore
1851 since the silc_packet_receive_process will determine now
1852 whether the packet is normal or special.
1854 * Implemented the unidirectional MAC keys. Affected files
1855 lib/silcske/silcske.c, silcd/protocol.c and
1856 lib/silcclient/protocol.c.
1858 * Implemented the packet sequence number to the MAC computation.
1859 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1860 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1861 lib/silcclient/protocol.c.
1863 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Allow backup router to announce servers. All servers
1866 announced by backup router are added to the global list
1867 automatically. Update hte server's socket to our primary
1868 router also when backup router announces a server.
1869 Affected file silcd/packet_receive.c.
1871 * Do not update the client->router in the function
1872 silc_server_udpate_clients_by_server if the client is on
1873 global list. We might fail to find any specific server
1874 for locally connected clients and local cell clients. They
1875 should still use the `from' and not `to' as client->router.
1876 This fixes backup router resuming protocol. Affected file
1877 silcd/server_util.c.
1879 * Decrease channel statistics count only if the channel
1880 deletion worked. Affected files are silcd/server.c and
1881 silcd/server_util.c.
1883 * Added silc_server_update_servers_by_server to update origin
1884 of all server entries. Used during backup router protocol.
1885 Affected files silcd/server_util.[ch], silcd/server.c. and
1886 silcd/backup_router.c.
1888 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1889 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1890 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1891 lib/silccrypt/silchmac.c.
1893 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1895 * Assure that router cannot reroute the same channel message
1896 to the sender. Affected file silcd/packet_receive.c.
1898 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Made better checks that the channel message is not sent
1901 to the router it came from. Affected file is
1902 silcd/packet_send.c. Fixed memory leak too.
1904 * Announce informations for incoming router connection, but
1905 only after checking if it is replaced by backup router.
1906 Affected file silcd/packet_receive.c.
1908 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Fixed the backup resuming protocol to work in multiple
1911 router environment. Affected file silcd/server_backup.c.
1913 * Route packet only to one router in the function
1914 silc_server_packet_send_to_channel. Affected file is
1915 silcd/packet_send.c.
1917 * Fixed silc_server_send_notify_dest to set the broadcast
1918 flag. Fixed the silc_server_send_notify_topic to actually
1919 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1920 Affected file silcd/packet_send.c.
1922 * Changed the SFTP Filesystem interface. Changed the
1923 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1924 the filesystem operation function. The SilcSFTPFilesystem
1925 is now a context that is allocated by all filesystem allocation
1926 functions and it already includes the operations structure
1927 and filesystem specific context. It is given as argument
1928 now to the silc_sftp_server_start. This made the interface
1929 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1930 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1932 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * Changed the backup router adding and getting interfaces
1935 in the server. The router that will be replaced by the
1936 specified backup router is now sent as argument. Affected
1937 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1940 * Added silc_net_addr2bin_ne to return the binary form of
1941 the IP address in network byte order. Affected files
1942 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1944 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Check for existing server ID in silc_server_new_server
1947 and in silc_server_connect_to_router_final and remove the
1948 old entry if it exists. Affected file silcd/packet_receive.c,
1951 * Send the channel message always to only one router, either
1952 in upstream or downstream. Affected file is
1953 silcd/packet_send.c.
1955 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1957 * Wrote the definition of the backup resuming protocol to the
1958 protocol specification.
1960 * Removed one redundant channel key generation from normal
1961 server during joining procedure. Removed one redundant
1962 channel key sending from server to router during joining
1963 procedure. Affected file silcd/command.c.
1965 * Made minor bugfixes to the backup router resuming protocol.
1966 Affected file silcd/server_backup.c, server.c.
1968 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * Added --disable-asm configuration option. Affected files
1971 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1974 * Implemented the backup resuming protocol that is used to
1975 resume the primary router position in the cell after the
1976 primary router comes back online. Affected files
1977 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1978 and silcd/server_util.[ch].
1980 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1982 * Sleep two (2) seconds after sending QUIT command to server.
1983 Affected file lib/silcclient/command.c.
1985 * Assure that if outgoing data buffer is pending do not force
1986 send any data. Affected file silcd/packet_send.c.
1988 * Assure that if outgoing data buffer is pending do not force
1989 send any data. Affected file lib/silcclient/client.c.
1991 * Implemented the backup router support when the primary router
1992 goes down. The servers and routers can now use the backup
1993 router as new primary router without loosing connectivity.
1995 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1998 in the server to indicate disabled entry. All data read
1999 from the connection will be ignored and no data is sent
2000 for entry that is disabled. Affected files are
2001 silcd/idlist.h, silcd/server.c.
2003 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2005 * Created SFTP client and server test programs in the
2006 lib/silcsftp/tests directory.
2008 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Implemented memory filesystem (virtual filesystem) for
2011 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2014 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * Implemented the SFTP (SSH File Transfer Protocol) to the
2017 lib/silcsftp. It includes SFTP client and SFTP server
2020 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Moved lib/silccore/silcprotocol.[ch] to the
2023 lib/silcutil library.
2025 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2026 take variable argument list pointer as argument. Affected
2027 file lib/silcutil/silcbuffmt.[ch].
2029 * Added silc_buffer_set function that is used to set data
2030 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2031 Affected file lib/silcutil/silcbuffer.h.
2033 * Changed various routines in the core library to use the new
2034 silc_buffer_set instead of allocating new buffer only for
2037 * Added 64-bit value formatting and unformatting support to the
2038 silc_buffer_[un]format routines. Affected file is
2039 lib/silcutil/silcbuffmt.[ch].
2041 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2042 to includes/bitmove.h.
2044 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Fixed channel user mode saving in client library. Affected
2047 file lib/silcclient/command[_reply].c.
2049 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2051 * Defined the file transfer to the SILC Protocol. Added
2052 new packet type SILC_PACKET_FTP and defined File Transfer
2053 Payload. The mandatory file transfer protocol is SFTP
2054 (SSH File Transfer Protocol). Affected file in addition
2055 of the internet draft is lib/silccore/silcpacket.h.
2057 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2058 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2059 is used as part of backup router protocol when the primary
2060 router of the cell is back online and wishes to resume
2061 the position as primary router.
2063 * Redefined the MAC generation keys in the protocol. The
2064 same key is not used anymore in both direction. Both
2065 direction will now use different keys for sending and
2066 receiving. This fixes a potential security flaw. This
2067 change causes incompatibilities in the protocol.
2069 * Redefined also the MAC computation from the packet.
2070 An packet sequence number is now added to the MAC
2071 computation. This prevents possible replay attacks against
2072 the protocol. This change too causes incompatibilities
2075 Added `sequence' field to the SilcPacketContext to hold
2076 the current sequence number for the packet.
2078 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2080 * Added `created' field to the SilcIDListData in the file
2081 silcd/idlist.h to indicate the time when the entry was
2084 * Added `created' field to the SilcChannelEntry too. Affected
2085 file silcd/idlist.h.
2087 * Added `creation_time' aguments to all the announcement functions
2088 in the server. If it is provided then only the entries that
2089 was created after the provided time frame are actually
2090 announced. Affected file silcd/server.[ch].
2092 * The protocol says that the Channel ID's IP address must be
2093 based on the router's IP address. Added check for this in
2094 the silc_server_new_channel when processing incoming New Channel
2095 Payload. Affected file silcd/packet_receive.c.
2097 * Print out the correct version with --version in SILC client.
2098 Affected file irssi/src/silc/core/silc-core.c.
2100 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Fixed WHOWAS command to check for completnes of the client
2103 entry always, not just when the command is coming from client.
2104 Affected file silcd/command.c.
2106 * Added new function silc_server_packet_queue_purge to purge the
2107 outgoing data queue to the network. After the function returns
2108 it is guaranteed that the outgoing packet queue is empty.
2109 Affected file silcd/packet_send.[ch].
2111 * Purge the outgoing packet queue in the rekey protocol's final
2112 callback to assure that all rekey packets go to the network
2113 before quitting the protocol. Affected file silcd/server.c.
2115 * Added silc_client_packet_queue_parse as similar function as
2116 in server to the client library. The affected file is
2117 lib/silcclient/client.c.
2119 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2121 * Splitted silcd/server.c and created silcd/server_util.[ch]
2122 for utility functions.
2124 * Added new socket flag SILC_SF_DISABLED to indicate that the
2125 connection is open but nothing can be sent to or received from
2126 the connection. Affected file lib/silcutil/silsockconn.[ch].
2127 The checking for disabled socket is checked in the low level
2128 silc_socket_write and silc_socket_read functions.
2130 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2132 * Allow only nicknames and channel names that fits into the
2133 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2135 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2137 * When processing JOIN command reply in server check that if
2138 the channel exists in our global list we'll move it the local
2139 list. Affected file silcd/command_reply.c.
2141 * Fixed the check whether client is joined on the channel already
2142 in JOIN command. Affected file lib/silcclient/command.c.
2144 * Fixed the JOIN command reply to check whether the channel
2145 already exists. Affected file lib/silcclient/command_reply.c.
2147 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Added silc_ske_status_string to map the SKE error numbers
2150 to readable strings. The affected files are
2151 lib/silcske/silcske[_status].[ch].
2153 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2155 * Do not show the private channels on the WHOIS channel list
2156 as it is not allowed by the protocol. The affected file is
2159 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Assure that the packet length digged from the actual packet
2162 is something sensible in the silc_packet_decrypt_rest_special
2163 in lib/silccrypt/silcpacket.c.
2165 * Free and NULL the allocated pointer in silc_hmac_alloc if
2166 the HMAC allocation fails. The affected file is
2167 lib/silccrypt/silchmac.c.
2169 * Print the selected security properties to the log files in
2170 the server. Affected file silcd/protocol.c.
2172 * Add SKE's reference counter even if calling the completion
2173 callback manually. Otherwise it goes negative, although it
2174 does not cause any problems. The affected file is
2175 lib/silcske/silcske.c.
2177 * Remove the client entry with short timeout after giving the
2178 KILL command. Affected file lib/silcclient/command.c.
2180 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2181 case all found clients are already disconnected (WHOWAS would
2182 found them) in the server. Affected file silcd/command.c.
2184 * Update the last_receive (time of last data received) to be
2185 updated only when received private or channel message so that
2186 the idle time showed in WHOIS makes more sense.
2188 * Added boolean field `valid' in to the SilcClientEntry in the
2189 client library to indicate whether the entry is valid or not.
2190 This fixes the nickname change bug on channel when changing
2191 the nickname to be same than the old (like nick to Nick) the
2192 nickname formatter doesn't set the new nick anymore to Nick@host.
2193 Affected file lib/silcclient/idlist.[ch].
2195 * Now actually fixed the nickname changing on disconnection.
2196 Added new function silc_change_nick to the Irssi SILC Client.
2197 Affected file irssi/src/silc/core/client_ops.c,
2198 irssi/src/silc/core/silc-nicklist.[ch].
2200 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2202 * Check that the public key exists in the GETKEY command before
2203 trying to encode it. Affected file silcd/command.c.
2205 * Print some notifications on received public keys with GETKEY
2206 command in the Irssi SILC Client. Affected files are
2207 irssi/src/fe-common/silc/module-formats.[ch],
2208 irssi/src/silc/core/client_ops.c.
2210 * Use IDENTIFY command to resolve the server information in the
2211 GETKEY command instead of INFO command. Affected file
2212 lib/silcclient/command.c.
2214 * All command reply functions in the client library now calls
2215 the pending command reply callbacks even if an error has
2216 occurred. The server has done this a long time and now it was
2217 time to move the client library to this as well. Now all
2218 errors can be delivered back to the pending command reply
2219 callbacks if necessary. Affected files are
2220 lib/silcclient/command[_reply].[ch].
2222 * Change the nickname on disconnection back to the username
2223 because in reconnect the server will enforce it to it anyway.
2224 Affected file irssi/src/silc/core/silc-servers.c.
2226 * Fixed a config file parsing bug in the Irssi SILC client.
2227 Affected file irssi/src/silc/core/clientconfig.c.
2229 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * When printing the channel mode on JOIN, verify that the
2232 channel key and channel's HMAC are valid. Affected file
2233 irssi/src/silc/core/client_ops.c.
2235 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2238 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2239 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2241 * Removed channel key rekey task deleting from the function
2242 silc_server_save_channel_key. Affected file silcd/server.c.
2243 Added explicit timeout task context instead that is used to
2244 delete the task if we are registering a new task before the
2245 new task has elapsed.
2247 * When channel key rekey occurs the client library now saves
2248 the old channel key for a short period of time (10 seconds) and
2249 is able to use it in case some is still sending channel
2250 messages encrypted with the old key after the rekey. Affected
2251 file lib/silcclient/[idlist.h|client_channel.c].
2253 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2255 * Added check to the silc_server_new_id_real to not accept
2256 new ID if it is the sender's own ID. Affected file is
2257 silcd/packet_receive.c.
2259 * Assure that we do not announce ourself or the one we've
2260 sending our announcements when we're router and are announcing
2261 servers to our primary router. Affected file silcd/server.c.
2263 * Fixed silc_server_command_identify_check_client to assemble
2264 correct WHOIS packet. It send corrupted WHOIS packet and
2265 caused problem with router to router connections. Affected
2266 file silcd/command.c.
2268 Fixed also silc_server_command_whois_check the same way
2269 as for the IDENTIFY command.
2271 * Added new SilcIDListStatus to the server in the SilcIDListData
2272 structure. The status now includes the current status of
2273 the entry (like registered, resolved etc.). Affected file
2274 silcd/idlist.[ch]. Defined a bunch of different status types
2275 as well. This replaced the old boolean registered field as well.
2277 Added resolve_cmd_ident field to the SilcClientEntry structure
2278 too so that if the entry is for example being resolved so
2279 another command may attach to the same pending command reply
2280 without requiring to resolve the same entry again. This concept
2281 should optimize the WHOIS and the IDENTIFY resolving under
2282 heavy load by taking away unnecessary resolving for entries
2283 that are being resolved already.
2285 Added support for adding multiple pending commands for one
2286 command idenfier. Affected file silcd/command[_reply].[ch].
2288 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2289 before deleting the data. Otherwise the hash table will have
2290 freed data in comparison functions. Affected file is
2291 silcd/command_reply.c.
2293 * Fixed silc_idlist_replace_client_id to add the new entry to
2294 the cache with NULL nickname. Otherwise there will be invalid
2295 memory as the nickname after the nickname is freed. Affected
2296 file silcd/packet_receive.c.
2298 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2299 saved into wrong slots because the previous number of entries
2300 was not taken into account. Affected file silcd/idlist.c.
2301 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2303 * If we are router and we receive JOIN notify to a channel that
2304 does not have any users then notified client is marked as the
2305 channel founder, as it is it. The affected file is
2306 silcd/packet_receive.c
2308 * Added to the extended hash table API's table_del_*ext functions
2309 the destructor as argument too, so that the caller can decide
2310 which destructor to use or whether to use destructor at all.
2311 Affected file lib/silcutil/silchashtable.[ch].
2313 * Fixed ID Cache purging. It actually deleted the entries from
2314 the hash table after the data was freed. The hash table ended
2315 up comparing freed memory. The affected file is
2316 lib/silccore/silcidcache.c.
2318 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2320 * Fixed Irssi SILC client's KILL command's HELP syntax.
2322 * The USERS command now resolves the detailed user information
2323 if the userinfo field is missing. Affected file is
2324 lib/silcclient/command_reply.c.
2326 * Do not print error in silc_file_read if the read file does
2327 not exist. Just silently return NULL. Affected file is
2328 lib/silcutil/silcutil.c.
2330 * Fixed the silc_log_output to not wine about NULL filename
2331 and to not create some bogus " " filename. Affected file is
2332 lib/silcutil/silclog.c.
2334 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2336 * Fixed various printing bugs on the user interface in the
2337 Irssi SILC Client. Minor changes that were forgotten from
2340 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2342 * Fixed the configure.in.pre and the compilation and distribution
2343 environment to support the new autoconf 2.52. That version is
2344 now required to compile the CVS trunk.
2346 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2348 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2349 to generally parse user@fqdn format strings. Affected file
2350 lib/silcutil/silcutil.c.
2352 * Added nickname_format and nickname_force_format fields to the
2353 SilcClientParams structure. The first one defines the format
2354 for the nicknames that the library will enforce if the receives
2355 multiple same nicknames. The second one is boolean value and
2356 can be used to force the library to always enforce the format
2357 to the nicknames regardles whether there are multiple nicknames
2358 or not. This configurable formatting was employed to flexibly
2359 support accessing multiple nicknames from the user interface.
2360 The userinterface can now set the nicknames to what ever format
2361 they prefer. Affected file lib/silcclient/silcapi.h.
2363 Added function silc_client_nickname_format to the file
2364 lib/silcclient/idlist.c. It performs the nickname formatting.
2366 Added new field `hostname´ to the SilcClientEntry context.
2367 It holds the hostname of the client. Affected file is
2368 lib/silcclient/idlist.h.
2370 * Irssi SILC Client sets the nicknames in nick@hostn format.
2371 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2372 irssi/src/silc/core/silc-core.c.
2374 The WHOIS printing now also shows both the real nickname and
2375 the formatted nickname so that user knows how to access the
2376 user if there are multiple same nicknames cached. Affected
2377 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2378 printing formatting too to take the hostname now as a separate
2379 argument. The Affected file is
2380 irssi/src/fe-common/silc/modules-formats.[ch].
2382 * Changed the silc_client_get_clients_local to accept the formatted
2383 nickname as argument. It accepts the real nickname too but the
2384 formatted nickname can be used to find the true entry from
2385 multiple entries. Affected file lib/silcclient/silcapi.h and
2386 lib/silcclient/idlist.c.
2388 * Added nickname_format_parse field to the SilcClientParams.
2389 It is a callback function provided by the application to parse
2390 the nickname out of the formatted nickname string. The library
2391 calls it to get the nickname from the formatted string. Since
2392 the application generally knows better the format of the nickname
2393 string it parses it instead of the library, even though library
2394 encodes the formatted string. If the callback function is not
2395 provided then the library will use the string as is. The
2396 affected file is lib/silcclient/silcapi.h.
2398 * All the nickname strings passed to the client library in
2399 commands are now expected to be formatted nickname strings.
2400 If the command does not support the formatted nickname string
2401 it will assume that the sent string is the actual nickname.
2402 Affected file lib/silcclient/command.c.
2404 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2406 * Added public key authentication support to OPER and SILCOPER
2407 commands in the client library. Affected file is
2408 lib/silcclient/command.c.
2410 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2412 * Changed the get_auth_methdod client operation to be asynchronous.
2413 It can be async if the application resolves the authentication
2414 method from the server during the negotiation. Added new
2415 SilcGetAuthMeth completion callback that the application will
2416 call after resolving the authentication method.
2418 Added function silc_client_request_authentication_method that
2419 the application can use to resolve the authentication method
2420 from the server. Added also SilcConnectionAuthRequest callback
2421 that the library will call after the server has replied. The
2422 application can call this function if it does not know the
2423 current authentication method.
2425 Affected files are lib/silcclient/client.c and
2426 lib/silcclient/silcapi.h.
2428 * The Irssi SILC client now automatically resolves the authentication
2429 method incase any configuration information is not present (and
2430 currently there never is). The affected file is
2431 irssi/src/silc/core/client_ops.c.
2433 * Fixed public key authentication from the client library.
2434 Affected file lib/silcclient/protocol.c. Changed also the
2435 protocol specification about the public key authentication in
2436 the connection authentication protocol. The actual data to be
2437 signed is now computed with a hash function before signing.
2439 * Fixed the public key authentication from the server as well.
2440 Affected file silcd/protocol.c.
2442 * Removed the mlock()'s from the memory allocation routines.
2443 Affected file lib/silcutil/silcmemory.c. The ./configure does
2444 not check anymore for the mlock(). Affected file is
2447 * Fixed USERS command in server to allow the execution of the
2448 command for private and secret channels if the client sending
2449 the command is on the channel. Affected file silcd/command.c.
2451 * Fixed silc_client_get_clients_local to return the clients
2452 count correctly. It could return wrong value. Affected file
2453 lib/silcclient/idlist.c.
2455 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2457 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2458 types. The assembler optimizations seemed not to like 64-bit
2459 data types. The assmebler optimizations thus are now enabled
2460 also for BSD systems as opposed to only enable them for Linux.
2462 * Do not check for threads at all on BSD systems. Affected
2463 file configure.in.pre.
2465 * Removed -n and -h options from the Irssi SILC Client since
2466 they are not used in silc.
2468 * Fixed the prime generation to assure that the first digit
2469 of the generated random number is not zero since our conversion
2470 routines does not like number strings that starts with zero
2471 digit. If zero digit is seen the random number is regenerated.
2472 This caused some corrupted RSA keys when the zero first digit
2473 was met. Affected file lib/silcmath/silcprimegen.c.
2475 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Fixed WIN32 configuration in the ./configure script.
2478 Fixed to include xti.h on environments that has it.
2479 Patches by Carsten Ilchmann and andrew.
2481 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Changed the silc_id_create_client_id to be collision
2484 resistant. It is now assured that there cannot be created
2485 two same client ID's. I suspect that some weird bugs in
2486 the server were actually caused by duplicate Client IDs.
2487 Affected file silcd/serverid.[ch]. A router receiving
2488 new ID now also assures and informs the sending server
2489 if the ID caused collision.
2491 * Changed the silc_id_create_channel_id to also assure that
2492 there are no collisions.
2494 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Statement about ignoring the Mutual Authentication flag when
2497 performing rekey with PFS was a bit misleading. It is ignored
2498 if it was set in the initial negotiation, it cannot be even
2499 set in the rekey. Fixed in the ke-auth draft. Started the
2500 new versions of the protocol drafts in the doc/.
2502 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * Fixed a bug in silc_client_command_identify_save when saving
2505 new channel information. The channel name was no duplicated
2506 and caused crash on exit. Affected file is
2507 lib/silcclient/command_reply.c.
2509 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2511 * Fixed the getkey command handling in the server. Send just
2512 empty OK reply to the sender if the key could not be fetched
2513 (but everything else was ok, like the key just was not available).
2514 Changed the public key parameter to optional in the protocol
2515 specs so that empty OK reply can be sent. Affected file
2518 Added a message to Irssi SILC client to tell to user if the
2519 server did not return a public key.
2521 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2523 * Fixed a channel key regeneration bug. It registered new
2524 timeout tasks exponentially until all system resources were
2525 used. Affected file silcd/server.c.
2527 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2529 * Added the SILC Document generator to the scripts/silcdoc.
2530 It can be used to generate the Toolkit Reference Manual out
2531 of the source tree. Internally it will also use the RoboDoc
2532 generator now imported in util/robodoc.
2534 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Added couple of return's in rekey protocol if error orccurred
2537 during the protocol. The execution must be terminated.
2538 Affected file silcd/protocol.c. Also, terminate the protocol
2539 always with timeout.
2541 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2543 * The client's Client ID was created initally from the wrong
2544 nickname (it could have been in format nick@host) in the
2545 silc_server_new_client. Affected file silcd/packet_receive.c
2547 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2549 * Added some SILC_LOG_ERROR's to various error conditions
2550 if client could not be added to ID cache. Affected files
2551 silcd/packet_receive.c and silcd/server.c.
2553 * When client's sock->user_data is freed, NULL also the
2554 client->router and client->connection pointers. Added check
2555 for these pointers being NULL to various places around the
2556 code. Affected file silcd/server.c.
2558 * Added client->data.registered == TRUE checks to various
2559 places around the code to assure that unregistered client's
2560 are not handled when it is not allowed. Affected file
2563 * Added `bool registered' fields to all
2564 silc_idlist_[server|client]_get_* routines to indicate whether
2565 the fetched client needs to be registered or not. Affected
2566 file silcd/idlist.[ch].
2568 * Add your own entry as registered to the ID cache in the
2569 server. Affected file server.c.
2571 * Fixed a bug in silc_server_new_server. The SilcServer was
2572 set as the new server's context instead of SilcServerEntry.
2573 This naturally caused some weird bugs.
2575 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2577 * Do not delete the channel rekey task when adding it
2578 for in silc_server_create_channel_key.
2580 * Changed the silc_server_create_channel_key to return
2581 TRUE or FALSE to indicate the success of the channel key
2584 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Fixed MSVC++ project files and added missing files to
2587 Makefiles under win32/.
2589 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2591 * Do not add TCP_NODELAY flag if the operating system
2592 does not have it defined. Affected files are
2593 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2595 * Fixed buffer overflow from Irssi SILC Client. Affected
2596 file irssi/src/fe-common/core/themes.c.
2598 * Fixed double free in client library in the file
2599 lib/silcclient/client.c when disconnecting from server.
2601 * Applied double free patch from cras to Irssi SILC client.
2602 Affected files irssi/src/core/[modules/expandos].c
2604 * Fixed the disconnection handling to Irssi SILC Client.
2605 The application must call silc_client_close_connection
2606 in ops->connect client operation in case of failure of
2607 the connection. Affected file is
2608 irssi/src/silc/core/client_ops.c.
2610 * Do not set sock->protocol to NULL in the function
2611 silc_client_close_connection after executing the protocol's
2612 final callback since the sock might not be valid anymore.
2613 Affected file lib/silcclient/client.c.
2615 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Do not enable SILC_THREADS if the linking with libpthread
2618 did not happen. Affected file configure.in.pre.
2620 * Added notion to protocol specification that server must
2621 verify the sent authentication payload with CMODE when
2622 setting the channel founder key. Implemented it to the
2623 server. Affected file silcd/command.c.
2625 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2627 * Added _EXTRA_DIST SILC distribution variable to the
2628 distributions file. It is used to conditionally add extra
2629 files or directories to the specific distribution. Affected
2630 files ./prepare, Makefile.am.pre and distributions.
2632 Removed the `_' from the start of the distribution names.
2635 * Added README.WIN32 for instructions to compile the Toolkit
2638 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2640 * Fixed a double free in disconnection in the server. Affected
2641 file is silcd/server.c.
2643 * Fixed the lib/silcske/groups.c to work now also with GMP
2644 MP library. The string conversion did not work when using
2645 specific base and the base is indicated in the string as well.
2647 * Created win32/ directory which now includes MSVC++ specific
2648 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2649 It will appear only in the toolkit distribution
2651 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * Changed the key material distribution function in case when
2654 the hash output is too short. The data is now concatenated
2655 a bit differently than it used to. Made the change to the
2656 SKE protocol specification.
2658 * Added better GMP detection to configure.in.pre. A patch
2661 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2663 * Fixed a minor bug in SKE that might cause some problem on
2664 some platforms. Affected file lib/silcske/silcske.c.
2666 * Added the cookie checking for initiator in the SKE. It checks
2667 that the responder returns the sent cookie unmodified. The
2668 affected file is lib/silcske/silcske.c. Added new SKE
2669 error type INVALID_COOKIE that can be sent during the
2670 negotiation. Fixed some memory leaks as well.
2672 * Added the "invalid cookie" error message to Irssi SILC client's
2675 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2677 * Added `task_max' field to the SilcClientParams to indicate
2678 the maximum tasks the scheduler can handle. If set to zero,
2679 default values are used. Affected file lib/silcclient/silcapi.h.
2681 * Fixed memory leaks in silc_client_close_connection. Affected
2682 file lib/silcclient/client.c.
2684 * Added silc_client_del_client_entry to client library to free
2685 all memory of given client entry. Affected file is
2686 lib/silcclient/idlist.[ch].
2688 * Added new functions silc_client_del_channel and
2689 silc_client_del_server to delete channel and server entries.
2690 Affected file lib/silcclient/[silcapi.h/idlist.c].
2692 * Removed silc_client_del_client_by_id from silcapi.h.
2694 * Fixed the INFO command to return the server's own info
2695 correctly when querying by Server ID. Affected file is
2698 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Removed the non-blocking settings in WIN32 code in the
2701 silc_sock_[read/write] and added SleepEx instead. Affected
2702 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2703 of input data is now checked with FIONREAD and ioctlsocket.
2705 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2707 * Call silc_schedule_task_del_by_context in the
2708 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2709 Affected file lib/silccore/silcprotocol.c.
2711 * Call silc_protocol_cancel for active protocols in the
2712 silc_server_close_connection if the funtion
2713 silc_server_free_sock_user_data has not been called.
2714 Affected file silcd/server.c.
2716 * Generic tasks cannot be deleted using the del_by_fd
2717 task deleting function since generic tasks does not match
2718 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2720 * Added a notion to SILCOPER help file that the SILCOPER works
2721 only on router server, not on normal server.
2723 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * Added for WIN32 support for the new scheduler as well.
2726 Affected file lib/silcutil/win32/silcwin32schedule.c.
2728 * Fixed the SHA1 implementation to work on various platforms.
2730 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2732 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2733 API. It is part of the scheduler now. Everything else is
2734 as previously but some functions has changed their names.
2735 Checkout the lib/silcutil/silcschedule.h for the interface.
2736 Updated all applications to use the new interface. Affected
2737 files are lib/silcutil/silcschedule.[ch].
2739 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Found a bug in the SKE implementation. The HASH value,
2742 specified by the protocol, was not computed correctly. The
2743 public key of the responder was not added to the computation
2744 even though it is mandatory. Affected file lib/silcske/silcske.c.
2745 This unfortunately causes incompatibilities with older
2746 clients and servers.
2748 * Added WIN32 specific network init and uninit functions:
2749 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2750 the Winsock2. Affected file lib/silcutil/silcnet.h and
2751 lib/silcutil/win32/silcwin32net.c.
2753 * Set the socket always to nonblocking mode on WIN32 after
2754 reading data or writing data. Affected file is
2755 lib/silcutil/win32/silcwin32sockconn.c.
2757 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2759 * Fixed various compilation problems under WIN32. Affected
2760 files lib/silcutil/win32/silcwin32thread.c and
2761 lib/silcutil/win32/silcwin32schedule.c.
2763 * Removed all _internal.h #includes from public header
2764 files. Internal headers must never be included from
2767 Removed also the lib/silcske/payload_internal.h file.
2769 * All include files that may be needed (public and some others
2770 included by the public headers) by application developers are
2771 now copied to the ./includes directory. It does not copy any
2772 internal headers. Affected file Makefile.defines.pre and all
2773 Makefile.am's under lib/ and subdirs.
2775 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2777 * Do not change the ~/.silc directory's permissions automatically.
2778 Affected file irssi/src/silc/core/clientutil.c.
2780 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2782 * Do not cancel the protocol in silc_server_close_connection
2783 it might cause recursion. Now cancelled in the function
2784 silc_server_free_sock_user_data. Affected file silcd/server.c.
2786 * Fixed the silc_server_remove_clients_by_server to regenerate
2787 the channel keys correctly finally. Added also new function
2788 silc_server_remove_clients_channels to actually do it.
2789 Affected file silcd/server.c.
2791 * Fixed the silc_server_new_channel to not crash by giving
2792 wrong router to the new channel. Affected file is
2793 silcd/packet_receive.c.
2795 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2798 which is given as argument to the silc_client_alloc now.
2799 It can be used to configure the client and set various parameters
2800 that affect the function of the client.
2802 * The USERS command in server did not check whether the channel
2803 is private or secret. Affected file silcd/command.c.
2805 * Added new argument to the USERS command in protocol specification.
2806 The USERS command now can take the channel name as argument
2807 as well. Added support for this in client and server and
2808 updated the protocol specs.
2810 * Completed the GETKEY command in client. It can be now used
2811 to fetch also servers public key not only some clients.
2812 Affected files lib/silcclient/command[_reply].c.
2814 * Added silc_client_get_server to return server entry by the
2815 server name. Affected files lib/silcclient/silcapi.h and
2818 * Redefined the IDENTIFY command in protocol specification to be
2819 more generic. It now can be used to query information about
2820 any entity in the SILC Network, including clients, servers and
2821 channels. The query may be based either the entity's name
2822 or the ID. Added support for this in both client and server.
2824 Affected files silcd/command.c and lib/silcclient/command.c
2825 and command_reply.c.
2827 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2828 the _from_client and _from_server functions. Affected file
2831 * Added silc_client_get_channel_by_id_resolve to the file
2832 lib/silcclient/silcapi.h to resolve channel information by
2833 its ID. Added also silc_client_get_channel_by_id that
2834 does not resolve it from the server.
2836 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2838 * Added SilcServerEntry context into the client library
2839 to represent one server. The INFO command now allocates
2840 these to save the resolved server info. For now on the
2841 client library will also keep information about servers,
2842 connected and resolved with INFO.
2844 The INFO command now allocates the SilcServerEntry context
2845 and saves the server info there. The COMMAND_REPLY in
2846 the INFO now returns the parameters to application in
2847 same order as defined in the protocol specification.
2849 The entries are cached in the client->server_cache.
2851 * The INFO command is now issued after received the Client ID
2852 from the server. Affected file lib/silcclient/client.c.
2854 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2855 to the application as the mode changer might be server.
2856 It is guaranteed that NULL is not returned anymore to the
2857 application. Affected file lib/silcclient/client_notify.c.
2859 The ID Type is now also passed to the application so that
2860 it can check whether the returned entry is SilcClientEntry
2863 Added new function silc_client_get_server_by_id to return
2864 the server entry by ID. Affected files are the
2865 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2867 * Do not create the channel in the Irssi SILC Client when issuing
2868 the JOIN command but when received the sucessful JOIN command
2869 reply. Otherwise the channel might get created even though we
2870 could not join it. The Affected file is
2871 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2873 * Fixed a channel joining bug in router. The router must also
2874 check the channel modes, invite and ban lists etc. when serving
2875 the JOIN command sent by normal server. Affected file is
2876 silcd/command.c. The router now resolves the client's
2877 information from the server who sent the JOIN command if it
2878 does not know it, and processes the JOIN command only after
2881 * Changed the SilcCommandCb to take new argument; void *context2.
2882 Affected file lib/silccore/silccommand.h
2884 The second argument in the command callbacks in the server now
2885 includes the SilcServerCommandReplyContext if the command was
2886 called as pending command callback from the command reply.
2887 Otherwise it is NULL. When called as pending the status of the
2888 command reply will be checked and if it was erronous the
2889 error will be sent to the original sender of the command.
2890 This way the client always receives the error messages even
2891 though the server was actually the one who received the error
2892 when it resent the command to router, for example. Affected
2893 files silcd/command[_reply].[ch].
2895 * Fixed sending WHOWAS command's error message to client if
2896 the requested client could not be found. It was missing.
2899 * Changed the CMODE and CUMODE commands reply arguments in the
2900 protocol specification. The Channel ID is now sent in both
2901 of the commands to identify the channel. Implemented this
2902 new feature to the client and server. Affected files
2903 lib/silcclient/command_reply.c and silcd/command.c.
2905 * Made better checks for invite and ban lists in the JOIN
2906 command in server. Affected file silcd/command.c.
2908 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * The server now performs the incoming host IP/DNS lookup
2911 using the silc_socket_host_lookup and thus does not block
2912 the server anymore. Affected file silcd/server.c.
2914 * Completed the multi-thread support for SILC Scheduler in
2915 the lib/silcutil/silcschedule.c.
2917 * Fixed the configure.in.pre to detect the pthread correctly
2920 * Fixed a deadlock in silc_task_queue_wakeup in the file
2921 lib/silcutil/silctask.c.
2923 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2925 * Added new function silc_schedule_wakeup that is used in
2926 multi-threaded environment to wakeup the main thread's
2927 schduler. It needs to be used when a thread adds a new task
2928 or removes a task from task queues. After waking up, the
2929 scheduler will detect the task queue changes. If threads
2930 support is not compiled in this function has no effect.
2931 Implemented the wakeup mechanism to both Unix and WIN32
2932 systems. Affected files are lib/silcutil/silcschedule.[ch],
2933 lib/silcutil/unix/silcunixschedule.c and the
2934 lib/silcutil/win32/silcwin32schedule.c.
2936 * Added new function silc_task_queue_wakeup to wakeup the
2937 scheduler by the specified task queue. Affected file
2938 lib/silcutil/silctask.[ch].
2940 * The silc_socket_host_lookup_start now wakes up the scheduler
2941 after adding the timeout task. Affected file is
2942 lib/silcutil/silcsockconn.c.
2944 * The silc_socket_host_lookup is synchronous now if the threads
2945 support is not compiled in. However, the callback is still
2946 called asyncronously through the scheduler, anyway. Affected
2947 file lib/silcutil/silcsockconn.c.
2949 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2951 * Added new function silc_socket_host_lookup to perform
2952 asynchronous IP and FQDN lookups for the socket connection.
2953 Affected files lib/silcutil/silcsockconn.[ch].
2955 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2957 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2958 that may or may not compile the mutex support in.
2960 Changed the silc_mutex_alloc interface. It allocates the
2961 mutex now to the sent pointer and returns TRUE or FALSE.
2963 Affected file lib/silcutil/silcmutex.h.
2965 * Wrote the SILC Task Queue interface to support multi-threads.
2966 Affected file lib/silcutil/silctask.[ch].
2968 * Wrote the SILC Scheduler to support multi-threads. Affected
2969 file lib/silcutil/silcschedule.c.
2971 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2974 in lib/silcutil/win32/.
2976 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * Defined SILC Mutex API and SILC Thread API and implemented
2979 them for Unix. Affected files are
2980 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2981 lib/silcutil/unix/silcunixmutex.c and
2982 lib/silcutil/unix/silcunixthread.c.
2984 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2986 * Fixed the silc_server_remove_clients_by_server's channel
2987 key re-generation. The hash table handling was incorrect
2988 and would not work with many channels. Affected file is
2991 * Fixed some memory leaks around the server code.
2993 * Rewrote the silc_server_get_users_on_channel to support IPv6
2994 based Client ID's. Affected file silcd/server.c.
2996 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2997 specification. However, a separate document must be written
2998 to define the detailed signing procedure and the payload
2999 associated with the flag. Defined the flag to the
3000 lib/silccore/silcchannel.h as well.
3002 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * Changed the dynamic tables to static size tables in the
3005 lib/silccrypt/silchmac.c.
3007 * Removed GCC dependencies from the code. A patch by cras.
3009 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3011 * Do not show the error "Error receiving packet bla bla"
3012 in server if it really was not an error (-2 means that reading
3013 is pending). Affected file silcd/server.c.
3015 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Fixed a possible crash in silc_server_remove_clients_by_server
3018 in silcd/server.c. Fixed there also some memory leaks.
3020 * Fixed the silc_idlist_replace_client_id. It could replace
3021 wrong key in the hash table. Affected file silcd/idlist.c.
3023 * Do not check whether there are global users on the channel
3024 if the channel->global_users is FALSE. Affected functions
3025 silc_server_remove_from_one_channel and
3026 silc_server_remove_from_channels in silcd/server.c. Also,
3027 do not check if the removed client is local as we can be
3028 sure that global client was not removed from the channel
3029 and checking for global users is not needed.
3031 * The silc_server_remove_clients_by_server now re-generates
3032 the channel keys correctly for those channels that had
3033 clients removed from them. Affected file silcd/server.c.
3035 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3037 * Found the reason of random crashes in the server. We weren't
3038 ignoring the SIGPIPE signal (which can be sent in write())
3039 and it crashed the server. Affected file silcd/silcd.c.
3041 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3043 * Assure that sock->user_data is not NULL in the function
3044 silc_server_packet_send in silcd/packet_send.c.
3046 * Disconnect the remote connection if it could not be added
3047 to any ID lists in the server. The affected file is
3050 * Check in silc_server_packet_send[_real/dest] that the
3051 socket is not disconnecting and ignore the data if it is.
3052 Affected file silcd/packet_send.c.
3054 * Define inline to __inline on native WIN32 compilation.
3055 Affected file includes/silcwin32.h.
3057 * Added some explicit type casts for inline code since MSVC
3058 require them. Affected files lib/silcutil/silcbuffer.h,
3059 lib/trq/silcdlist.h and lib/trq/silclist.h.
3061 * Print warning in log files from now on if the packet
3062 decryption fails. Affected file silcd/server.c.
3064 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Changed the `say' client operation's interface to accept
3067 new `type' argument to indicate the type of the message sent
3068 by the library. The application may filter the library's
3069 messages according the type. The affected file is the
3070 lib/silcclient/silcapi.h.
3072 * Added two new functions to lib/silcclient/silcapi.h:
3073 silc_client_del_client and silc_client_del_client_by_id.
3074 Affected file lib/silcclient/idlist.c.
3076 * Moved the clientincludes.h from includes/ to silc/ and
3077 serverincludes.h from includes/ to silcd/.
3079 * The modes for the CMODE and CUMODE are now passed as
3080 uint32 for application with COMMAND_REPLY. The affected
3081 file is lib/silcclient/command_reply.c.
3083 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3085 * /WHOIS without arguments shows client's own information.
3086 Affected file lib/silcclient/command.c.
3088 * Changed PING to not accept any arguments. The specs
3089 says that client can ping only the connected server so
3090 requiring an argument is not needed. Affected file is
3091 lib/silcclient/command.c.
3093 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3095 * Fixed a fatal bug in private message sending and reception
3096 encryption and decryption when using private message keys.
3097 The implementation was incorrect and did not follow the
3098 specification. It causd that some of the message were
3099 lost since it did not use the sending and receiving keys
3100 as the protocol suggests. This has been fixed and will cause
3101 incompatibilities with older clients when sending private
3102 message encrypted with private message keys. Affected files
3103 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3104 and various other in Irssi SILC Client.
3106 Added `responder' boolean argument to the functions
3107 silc_client_add_private_message_key[_ske] to indicate when
3108 the key is added as responder or initiator of the key
3111 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * Removed the silc_ske_check_version function and created
3114 a SilcSKECheckVersion callback. Added also a function
3115 silc_ske_set_callbacks that is now used to set all SKE
3116 callbacks. The callback functions are not given to
3117 the SKE functions anymore, but this function is used to
3120 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3122 * Added `silc_version' argument to the silc_client_alloc
3123 to define the version of the application for the library.
3124 The library will use the version string to compare it
3125 against the remote host's (usually a server) version
3126 string. Affected file lib/silcclient/silcapi.h
3128 * Added the KE protocol context to Key Agreement context
3129 in client library so that we can abort the SKE if it
3130 is in process when we get timeout. Affected file is
3131 lib/silcclient/client_keyagr.c.
3133 * Do not resolve the client ID forever if it returns in the
3134 first time that such client does not exist. This was done
3135 for example with private message. Affected file is
3136 lib/silcclient/client_prvmsg.c.
3138 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * Do not add regex.h for WIN32. The affected file
3141 includes/silcincludes.h.
3143 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3144 not work yet 100%. It generates the DLL's automatically
3145 when compiling with --with-win32 under cygwin.
3147 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3149 * lib/contrib/regex.c is not compiled on WIN32.
3151 * Added silc_net_get_socket_opt function to the
3152 lib/silcutil/silcnet.h.
3154 * Added includes/silcwin32.h for WIN32 specific includes
3157 * Do not use ptime structure or any of the posix process
3158 functions on WIN32 in lib/silccrypt/silrng.c.
3160 * Added silc_gettimeofday to provide generic function
3161 for struct timeval on all platforms. Added the function
3162 to lib/silcutil/silcutil.h.
3164 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3166 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3167 library as they clearly belong there. As a plus side we
3168 can make the actual socket connection routines platform
3171 Added also new generic function silc_socket_read and
3172 silc_socket_write (that used to be silc_packet_[read/write].
3173 The implementation of these are platform specific.
3175 * Added WIN32 specific routines of silc_socket_[read/write]
3176 to lib/silcutil/win32/silcwin32sockconn.c.
3178 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3180 * Added preliminary support for native WIN32 compilation under
3181 cygwin (using the -mno-cygwin option for GCC) to the
3182 ./configure.in.pre. The --with-win32 now prepares the
3183 compilation for native WIN32.
3185 * Rewrote the SILC Scheduler interface in the file
3186 lib/silcutil/silcschedule.h. The scheduler is now context
3187 based and does not have anymore any global static scheduler.
3188 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3189 and created lib/silcutil/win32 directory for WIN32 based
3192 * Added Unix specific network routines to the
3193 lib/silcutil/unix/silcunixnet.c and the old
3194 lib/silcutil/silcnet.c includes now only generic routines.
3196 Added WIN32 specific network routines to the
3197 lib/silcutil/win32/silcwin32net.c.
3199 * Added Unix specific utility functions from the
3200 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3202 * Added WIN32 SILC Scheduler to the file
3203 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3206 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3208 * Do not handle JOIN notify in the server if the target client
3209 is not registered (idata->registered == FALSE). The affected
3210 file is silcd/packet_receive.c.
3212 * Update the nickrec->founder in event_cumode in the Irssi SILC
3213 client. Affected file irssi/src/silc/core/silc-channels.c.
3215 * Fixed the CUMODE_CHANGE notify handling in the server when
3216 server and router are announcing their clients on channels.
3217 Now the mode changes are saved and notified correctly. The
3218 affected file is /silcd/packet_receive.c.
3220 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3221 They really did not replace the cache entry in the ID Cache.
3222 Now they do that. Affected file silcd/idlist.c.
3224 * Fixed the KICK notify handling in the Irssi SILC client to
3225 update the channel records so that the kicked client does not
3226 appear to be on the channel. The affected file is
3227 irssi/src/silc/core/silc-channels.c.
3229 * Always update the conn->current_channel when executing command
3230 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3232 * Fixed the KILL notify handling in Irssi SILC client to remove
3233 the killed client on all channels.
3235 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * Fixed the silc_parse_command_line to remove extra spaces
3238 from the start and end of the arguments. Affected file is
3239 lib/silcutil/silcutil.c.
3241 * Cancel and free any active protocol in the function
3242 silc_server_close_connection. Affected file silcd/server.c.
3244 * Cancel and free any active protocol in the function
3245 silc_client_close_connction. Affected file is
3246 lib/silcclient/client.c.
3248 * Do not execute the KILL command for clients that are in
3249 history (ie. they are not in the network). Affected file is
3252 * Fixed KILL notify handling, client does not crash anymore.
3253 Affected file irssi/src/silc/core/silc-channels.c.
3255 * Reduced the default packet buffer size from 2048 to 1024 in
3256 lib/silccore/silcpacket.c.
3258 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3259 counter to the SKE context that is incresed when the SKE library
3260 performs async operation outside the library. If the outside
3261 process frees the SKE context and FREED status will be set
3262 and the library will detect after the sync operation that the
3263 libary is freed. The affected files are
3264 lib/silcske/silcske[_status].[ch].
3266 * Resolve the client entry information in the function
3267 silc_client_channel_message to assure that NULL pointer is not
3268 passed as client entry to the application. */
3270 * Fixed the task timeout calculation to assure that there is
3271 never negative timeouts. The affected file is
3272 lib/silcutil/silcschedule.c.
3274 * Fixed the channel user mode notification sending in server.
3275 It was sent point-to-point to the router (or to server by router)
3276 but it needs to be destined to a channel. The routines now
3277 supports sending the channel user mode notifys to the channels
3278 when announcing clients and channels. Affected files are
3279 silcd/server.c and silcd/packet_receive.c.
3281 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3282 It did not actually replace the old channel entry in the cache.
3283 Affected file lib/silcclient/client_notify.c.
3285 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3287 * Fixed a possible crash in silc_packet_send_prepare. It now
3288 assures always that there is enough space in the buffer and
3289 at the tail area of the buffer (for MAC).
3291 Fixed the inbound buffer reallocation in silc_packet_read.
3292 It was old code and did not handle the reallocation correctly.
3295 The affected file is lib/silccore/silcpacket.c.
3297 * Fixed buffer overflow in silc_parse_nickname in the file
3298 lib/silcutil/silcutil.c.
3300 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * make install generates new server keys only if there is not
3305 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3308 Added check that if the NOREPLY is set then we will not send
3309 the away message. This avoids infinite loop of away messages
3310 if both clients are away. The affected file is
3311 lib/silcclient/client_prvmsg.c.
3313 * Fixed client crash if /NICK was given without arguments.
3314 Affected file lib/silcclient/command.c.
3316 * Server does not send the invite list in INVITE command back
3317 to the client if the list was not altered. Added this notion
3318 to the protocol spec as well. Affected file silcd/command.c.
3320 Fixed possible crash in INVITE command by checking the
3321 value of silc_server_get_client_route command.
3323 * Fixed the INVITE notify type handling. The arguments are now
3324 taken in correct order and client does not crash. The affected
3325 file is irssi/src/silc/core/silc-channels.c.
3327 Removed the "Inviting xxx to channel" message from the
3328 client library away and let the application handle it.
3329 Affected file lib/silcclient/command.c. Added that message
3330 to Irssi SILC client's message formats.
3332 * Fixed CMODE command crash in client. It now checks the
3333 amount of arguments correctly and does not crash. The affected
3334 file is lib/silcclient/command.c.
3336 * Do not create new channel automatically in silc_channels_join
3337 but check whether the channel by that name already exists.
3338 Affected file irssi/silc/core/silc-channels.c.
3340 * Do not send the SERVER_SIGNOFF to router if the disconnected
3341 entity was the router. Affected file silcd/server.c.
3343 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3344 SILC client as it was missing from there.
3346 Added the handling of the KICK notify to the Irssi SILC client
3347 as it was missing. Added "you have been kicked" message to
3348 Irssi SILC client's message modules formats.
3350 Added the handing of the KILL notify to the Irssi SILC client
3351 as it was missing. Added the kill message module formats
3354 The affected file is irssi/src/silc/core/silc-channels.c.
3356 * The router did not save the channel mode the server announced.
3357 Affected file silcd/packet_receive.c.
3359 * Fixed a possible crash in INFO command in server. If the
3360 server did not provide the server info it crashed. Affected
3361 file silcd/command.c.
3363 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3365 * Fixed the GETKEY command in the server to check also the
3366 global list. Otherwise the GETKEY would not work correctly
3367 in normal SILC server. Affected file silcd/command.c.
3369 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3371 * Fixed GETKEY crash, it crashed if the command did not succseed.
3373 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3375 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3376 is now real and not just an macro interface to GMP.
3378 Removed the entire GMP from the source tree and imported new
3379 NSS MPI library instead. Reason for removing GMP is that it is
3380 extremely large and compiles extremely slow. The NSS MPI
3381 is only a few files and compiles in less than 10 seconds.
3382 The speed is also about the same as GMP. The MPI is imported
3383 to lib/silcmath/mpi.
3385 If the system has GMP installed we will still use the GMP.
3386 If it is not then the NSS MPI will be compiled.
3388 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Merged a long nickname (127 characters long) crash bugfix from
3391 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3393 * Merged a freed memory reference bugfix from Irssi CVS tree.
3394 Affected file irssi/src/core/commands.c.
3396 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * Added the server's public key sving and verification to the
3399 server when performing the SKE. This was missing and the
3400 remote server's (or router's) public key was accepted without
3401 checking whether we have it previously or trust it at all.
3402 Affected file silcd/protocol.c.
3404 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * Check in the silc_server_timeout_remote if protocol is active
3407 and make sure that the protocol's final callback is called so
3408 that all memory if freed. Affected file silcd/server.c.
3410 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * silc_server_whois_send_reply crashed the server if the nickname
3413 was 127 characters long. Affected file silcd/command.c.
3415 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3417 * Added sanity check to the silc_server_new_client. If the hostname
3418 is provided inside username then check that the provided hostname
3419 really is the same as the resolved one. If the hostname was not
3420 resolved then check it from the public key. Affected file is
3421 silcd/packet_receive.c.
3423 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3424 if the server disconnected us and the connection is not valid
3425 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3427 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3428 the library to the lib/silcutil/silcutil.[ch].
3430 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3432 * Close log file after open. Affected file
3433 lib/silcutil/silclog.c.
3435 * Check whether sock == NULL in silc_client_send_packet and return
3436 if it is. Affected file lib/silcclient/silcclient.c.
3438 * Check rec->entry == NULL in the Irssi SILC Client before
3439 sending the channel message. Affecte file is
3440 irssi/src/silc/core/silc-servers.c.
3442 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3444 * Merged a splitted window bugfix from Irssi CVS tree. The
3445 affected file is irssi/src/fe-text/textbuffer-view.c.
3447 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3448 It did not print nickname.
3450 * Improved the distributions system a bit.
3452 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3455 irssi/src/fe-text/gui-window.c.
3457 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3458 to in-active server. The affected file is
3459 irssi/src/silc/core/client_ops.c.
3461 * Resolve the client in USERS command reply if the entry does
3462 not have username resolved. The affected file is
3463 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3464 command to WHOIS command to really resolve stuff. The USERS
3465 is not used any more in any critical section so WHOIS can
3466 be used even though it might be slower than IDENTIFY.
3468 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3471 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3473 * Changed the protocol API a bit more consistent in the
3474 lib/silccore/silcprotocol.[ch].
3476 * Changed the following headers to ROBODoc format:
3478 lib/silccore/silcpayload.h
3479 lib/silccore/silcprotocol.h
3480 lib/silccore/silcsockconn.h
3482 All core library headers are now formatted.
3484 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Fixed a bug in Irssi SILC client; do not show that you are
3487 server/router operator if you really are not. Affected file is
3488 irssi/src/silc/core/client_ops.c.
3490 * Renamed silc_command_free_payload to silc_command_payload_free.
3491 Affected file lib/silccore/silccommand.h
3493 * Added silcmath.h to include the prototoypes of various routines
3494 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3497 * Changed the following headers to ROBODoc format:
3499 lib/silccore/silcchannel.h
3500 lib/silccore/silccommand.h
3501 lib/silccore/silcid.h
3502 lib/silccore/silcidcache.h
3503 lib/silccore/silcmode.h
3504 lib/silccore/silcnotify.h
3505 lib/silccore/silcpacket.h
3506 lib/silcmath/silcmath.h
3508 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Added checking to the server code not to start the server if
3511 ciphers and stuff are not configured properly. Affected files
3512 silcd/serverconfig.[h] and silcd/server.c.
3514 * Changed the layout of the header files of the public interfaces
3515 in the SILC libraries. The new layout supports ROBODoc
3516 documentation tool (and some others) so that it is easy to create
3517 a library reference manual. All the other headers and source
3518 code must still follow the CodingStyle document. Also source
3519 code must not include these ROBODoc stuffs, only the headers.
3520 Furthermore, all public interface headers must now be named
3521 by using `silc' prefix, example: silcapi.h, silccipher.h.
3522 Some files were renamed due to this. All the other headers
3523 must not be used as public interfaces. I will update the
3524 CodingStyle document later. Changed following headers, so far:
3526 lib/silcclient/silcapi.h
3527 lib/silccore/silcauth.h
3528 lib/silccore/silcprivate.h
3529 lib/silccrypt/silcdh.h
3531 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Removed silc_client_packet_send_flush from the client library
3536 as it is not needed. Affected file lib/silcclient/client.[ch].
3538 * Added printing of message of unresolved authentication method
3539 to the Irssi SILC client. Added it to the module formats.
3540 Removed the same message from the client library.
3542 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3544 * Added new distribution feature, DISTLABEL. Every distribution
3545 can define own preprocessor label that can be used in the
3546 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3547 file distributions, acconfig.h.pre and prepare.
3549 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3551 * Added Makefile.defines_int to include the actual definitions
3552 for Makefile.defines.in. Tested the new distribution system,
3553 created distributions and tested installation.
3555 * Added AWAY message printing to the Irssi SILC client. Added
3556 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3558 * Added SCONNECT command to call the SILC's CONNECT command.
3559 Cannot use CONNECT directly since Irssi uses that internally.
3560 Affected file irssi/src/silc/core/silc-servers.c.
3562 Added ACTION local command. It is same as ME command but takes
3563 the channel as mandatory argument.
3565 Rewrote some of the Irssi's help files to suite for SILC
3568 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Added Makefile.defines[.in] that should for now on be included
3571 in all Makefile.am file in the source tree. That file includes
3572 all common compilation definitions for SILC source tree.
3574 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Minor changes to the ./prepare script to change the package
3577 name according the distribution name to the configure.in.
3579 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3581 * Created new distribution system. Added file `distributions'
3582 that defines all the distributions that can be created out of
3583 the SILC source tree. The ./prepare script now reads that
3584 file to determine how to prepare the distributions. The
3585 first argument to the ./prepare is the name of the distribution
3586 and second is the version of the distribution. If given
3587 without arguments it creates the default (toolkit) distribution
3588 with the default version (defined in ./prepare).
3590 All Makefile.am files that are subject to the distributions
3591 are now named as Makefile.am.pre. These are ./Makefile.am
3592 and lib/Makefile.am. Others may be changed later.
3594 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3596 * Added invite list, ban list, some key management and connection
3597 error message printing to module formats in the Irssi SILC client.
3599 * Added new silc_client_set_away_message to set the away message
3600 that is back to the person who sent private message. The
3601 affected file lib/silcclient/silcapi.h and the
3602 lib/silcclient/client_prvmsg.c.
3604 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Fixed the private message sending in the Irssi SILC client,
3607 added local command KEY to the Irssi SILC client.
3609 Added key management and key agreement message formats to the
3610 irssi/src/fe-common/silc/module-formats.[ch].
3612 Added USERS (alias WHO) printing, server/router operator
3613 indication and LIST command printing to the module formats.
3615 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3617 * Fixed channel joining notify handling, cumode notify handling
3618 from Irssi SILC client.
3620 * Added SILC specific module-formats to the Irssi SILC client so
3621 that SILC specific message hilighting, colors etc is possible.
3622 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3624 Added channel mode, channel user mode, actions, notices,
3625 whois and whowas printing to the the module-formats.c.
3627 * Fixed a bug in channel deletion in the server. The channel
3628 is not left to the cache even if the channel founder auth mode
3629 is set when there are no users anymore on the channel. Affected
3630 file silcd/server.c.
3632 * The silc_net_localhost now resolves the entire hostname including
3633 the domain name. Affected file lib/silcutil/silcnet.c.
3635 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * Changed the ask_passphrase client operation to be ascynchronous.
3638 It has now a completion callback and a context that the
3639 application must call after it has got the passphrase from
3640 the user. Affected files lib/silcclient/silcapi.h,
3641 lib/silcclient/protocol.c, lib/silcclient/command.c and
3644 Added SilcAskPassphrase callback that the application calls
3645 to deliver the passphrase to the library.
3647 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3648 The public key verification and especially a certificate
3649 verification is asynchronous procedure.
3651 Added new SILC_SKE_STATUS_PENDING status to indicate the
3652 request is pending and a callback will be called to finalize
3655 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3656 indicate that remote end did not send its public key (or
3657 certificate), even though we require it. Added check for this
3658 condition in the SKE. This was a security bug, now fixed.
3660 Defined new SilcSKEVerifyCbCompletion callback that is called
3661 when the verification process is completed.
3663 The affected files lib/silcske/silcske_status.h and
3664 lib/silcske/silcske.[ch].
3666 * Changed the verify_public_key client operation to be async
3667 as well. Defined SilcVerifyPublicKey callback that is used to
3668 indicate the success of the public key verification process.
3670 Changed the server and client to use the new async client
3673 * Changed the Irssi SILC client's internal scheduler to be called
3674 twice as many times as it used to be. As a result the client
3675 should be a bit faster now. Affected file is
3676 irssi/src/silc/core/silc-core.c.
3678 * Added support to Irssi SILC client of asynchronous public key
3679 verification and passphrase inquiry. Affected file is
3680 irssi/src/silc/core/silc-core.c.
3682 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Do not say "You have left channel %s" in client library.
3685 Moved it to the application. Affected files are
3686 lib/silcclient/command.c and silc/client_ops.c.
3688 * Fixed silc_client_get_clients. Command context was not
3689 duplicated and was freed memory in the callback. Affected
3690 file lib/silcclient/idlist.c.
3692 * Do not say "you are now talking..." on JOIN command in the
3693 client library. The appliation must handle it.
3695 * Do not say ".. changed topic to" in command reply in the
3696 client libary. The application must handle it.
3698 * Fixed TOPIC command sending in the client library.
3700 * Fixed a memory leak in silc_client_command_free in the file
3701 lib/silcclient/command.c.
3703 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Imported a modified version of Irssi client to the source tree.
3706 The Irssi will be used to create a new client called
3707 Irssi SILC. Imported to irssi/.
3709 Added silc_core_init_finish function to the Irssi. Affected
3710 file irssi/configure.in.
3712 A lot changes in the Makefile.ams around the irssi tree.
3714 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Do not rehash if the new size is same as the old size of the
3717 hash table, in the silc_hash_table_rehash*. The affected file
3718 lib/silcutil/silchashtable.c.
3720 * Replaced hash_table_del_by_context calls from the server
3721 (when channel->user_list and client->channels) to the
3722 hash_table_del as it is sufficient and faster.
3724 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Added silc_hash_table_list, silc_hash_table_get and the
3727 SilcHashTableList structure to provide an alternative way to
3728 traverse the hash table. The affected files are
3729 lib/silcutil/silchashtable.[ch].
3731 * Changed the server's idlist routines to use the hash table
3732 routines to optimize the code.
3734 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3736 * Replaced the client entry's `channel' list and channel entry's
3737 `user_list' list to hash tables for optimized lookup. Changed
3738 the code to use the hash table interface around the code.
3739 Affected file lib/silcd/idlist.[ch].
3741 * Added `auto_rehash' boolean argument to the function
3742 silc_hash_table_alloc to indicate whether the hash table should
3743 auto-rehash when it thinks is appropriate time. It will
3744 increase the hash table size if the there is twice as much
3745 entries in the table than the size of the table, and will
3746 decrease the size if there are twice as less entries than
3747 the size of the table.
3749 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3751 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3753 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * silc_idcache_purge_by_context deletes the entry now by context
3756 as it is supposed to do. Affected file lib/silccore/idcache.c.
3758 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3759 client is not anymore valid (WHOWAS givens the info) and not
3760 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3762 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Removed the `data' and `data_len' arguments from the ID Cache
3765 interfaces and added `name' argument. ID Cache does not handle
3766 anymore the binary data only a names associated with given ID.
3768 * When hashing a Client ID with silc_hash_id the entire ID is
3769 not hashed anymore, instead only the hash of the Client ID is
3770 hashed. This way we can access the Client ID from the cache
3771 with Client ID but with the hash of the ID (which is a hash of
3772 the nickname) as well without any difference in performance.
3774 Added also silc_idcache_find_by_id_one_ext to do one on one
3775 searching when we have the actual ID. Added also function
3776 silc_hash_client_id_compare. The affected files are
3777 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3779 * When hashing the name associated with a ID it is always done
3780 in lowercase. This way we can access the cache without worrying
3781 about case-sensitivity, even though, for example nicknames are
3784 * Fixed a bug in server with channel message sending. It put
3785 wrong ID type as destination ID. The affected file
3786 silcd/packet_send.c.
3788 * silc_idcache_del_by_context now deletes from all hash tables
3789 by context. Affected file lib/silccore/idcache.c.
3791 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Changed the client library to use the new ID Cache interface.
3794 Changes around the source tree.
3796 * Added silc_hash_table_rehash_ext to rehash with specific
3797 hash function. Affected file lib/silcutil/silchashtable.[ch].
3799 * Added silc_hash_string_compare to compare two strings in the
3800 hash table. Affected file lib/silcutil/silcutil.[ch].
3802 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Added new function silc_idcache_del_by_context into the
3805 lib/silccore/idcache.[ch].
3807 * Changed the server's ID list routines to use the new ID Cache
3808 interface. Changes around the source tree.
3810 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Added silc_hash_table_del[_by_context]_ext functions in to the
3813 lib/silcutil/silchashtable.[ch].
3815 Removed silc_hash_table_find_all* routines and added new
3816 silc_hash_table_find_foreach to replace them.
3818 Added silc_hash_table_replace_ext function as extended
3819 replacing function. Separated the simple hash table interface
3820 from the extended hash table interface in the file
3821 lib/silcutil/silchashtable.h.
3823 * Fixed minor bugs and changed it to use some of the new
3824 hash table functions in lib/silccore/idcache.c
3826 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * Added new function silc_hash_table_find_all to return all keys
3829 in the hash table by the specified key. As the hash table is
3830 collision resistant it also makes it possible to have several
3831 duplicate keys in the hash table. This function may be used to
3832 find all of the keys from the hash.
3834 Added user_context arguments to the SilcHashFunction,
3835 SilcHashCompare and SilcHashDestructor to deliver user specified
3838 Added new fuctions silc_hash_table_find[_all]_ext to do
3839 extended lookup with specified hash and compare functions and
3840 specified user contexts.
3842 Added new function silc_hash_table_add_ext to add the key
3843 with specified hash function and user context.
3845 Added new function silc_hash_table_foreach to traverse all
3846 entrys in the hash table. Added SilcHashForeach callback
3849 Added new function silc_hash_table_del_by_context to delete
3850 the entry only if the context associated with the key matches.
3852 Affected files are lib/silcutil/silchashtable.[ch].
3854 * Removed silc_hash_[server/client/channel]_id and added just
3855 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3856 silc_hash_id_compare to compare two ID's using as the hash table
3857 comparison function. Added also silc_hash_data to hash
3858 binary data and silc_hash_data_compare to compare it.
3860 * Removed silc_idlist_find_client_by_hash as it is not needed
3861 anymore. Affected file silcd/idlist.[ch].
3863 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3864 to use internally the SilcHashTable. The new ID Cache is a lot
3865 faster than the old one. Some of the ID Cache interface was also
3866 rewritten and obsolete and stupid functions were removed.
3868 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3870 * Added entry_count field to the SilcHashTable to keep the number
3871 of the entries in the table. Implemented the function
3872 silc_hash_table_rehash. Added new function
3873 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3875 Fixed a minor bug in silc_hash_table_free.
3877 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3878 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3879 into the lib/silcutil/silcutil.[ch].
3881 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * Implemented a collision resistant hash table into the
3884 lib/silcutil/silchashtable[ch]. See the header and the source
3885 for the SilcHashTable API.
3887 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Merged dotconf version 1.0.2 into lib/dotconf.
3891 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Do not compile anything in lib/silcsim/* if the SIM support
3894 is not enabled. The tree should now compile without problems
3897 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Compiled the SILC under cygwin. Compiled and tested briefly
3900 without problems. More tests needed. The SIMs didn't compile
3903 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3905 * Fixed possible crash in silc_get_username in the
3906 lib/silcutil/silcutil.c.
3908 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Fixed a va_arg in silc/client_ops.c.
3912 * Oops, RC5 routines were named AES and caused some problems
3913 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3915 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Added new SilcIDIP structure into the lib/silccore/id.h and
3918 replaced the old `ip' fields from all SILC ID's to that type.
3919 This is a step towards IPv6 support.
3921 The silc_id_get_len takes now the ID as an extra argument.
3922 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3923 both IPv4 and IPv6 based ID's.
3925 The affected files are lib/silccore/id.[ch] and other files
3926 around the tree using these routines.
3928 * Removed the ID length arguments in server from various
3929 silc_server_send_notify_* routines -> they are not needed
3932 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3934 * Fixed memory leak in silc_encode_pem_file in the file
3935 lib/silcutil/silcutil.c.
3937 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * Check minor version as well in the SKE. Affected files are
3940 silcd/protocol.c and lib/silcclient/protocol.c.
3942 * Added --identifier option to the server so that an identifier
3943 can be when creating the public key for the server. Affected
3944 file is silcd/silcd.c.
3946 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3947 lib/silccrypt/silcpkcs.c.
3949 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3951 * Register default ciphers and stuff when using -C option with
3952 the server. Affected file sildc/silcd.c.
3954 * Put back the servers public key filename format, it is better
3955 than the new one. For now, the client keys are saved with the
3956 new filename format. The affected file silc/client_ops.c.
3958 * Implemented the Cipher API for the rest of the ciphers that
3959 did not implement it or implemented it the wrong way.
3961 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3963 * Register default ciphers and stuff when using the -S option
3964 in the client. Affected file silc/silc.c. Same also when
3965 creating new key pair with -C option.
3967 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Fixed the silc_verify_public_key client operation function to
3970 save the public keys differently. The fingerprint is now
3971 used as filename and not the hostname. This way also the
3972 client keys are saved uniquely and not with hostnames. The
3973 affected file is silc/client_ops.c.
3975 * Trimmed the silc_hash_fingerprint function to remove extra
3976 whitespaces from the end of the fingerprint. The affected
3977 file is lib/silccrypt/silchash.c.
3981 * Added silc_cipher_register_default function to register all
3982 default ciphers. It can be used when configuration files
3983 does not exist and the application does not want any specific
3984 ciphers in any specific order.
3986 The SilcDList is now used as silc_cipher_list dynamically
3987 allocated cipher list. Removed the static list all together
3988 and now all ciphers must be allocated to the dynamic list.
3989 The silc_cipher_alloc routine was changed to check only the
3992 All silc_cipher_* routines that used to return int returns
3995 The affected files lib/silccrypt/silccrypt.[ch].
3997 * The same thing was done to silc_hash_* as for silc_cipher_*
3998 routines. Affected files lib/silccrypt/silchash.[ch].
4000 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4001 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4002 Added also silc_pkcs_[un]register[_default] functions.
4003 Removed the data_context from the PKCS API.
4005 * Added silc_hmac_register_default function to register default
4006 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4007 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4008 to unregister all hmacs at once.
4010 * Register the default ciphers, hash functions, PKCSs and HMACs
4011 if client's configuration file does not exist. The affected
4014 * The client did not load the hash functions from the SIM
4015 modules at all. Added support for this. Affected file is
4016 silc/clientconfig.c.
4018 * When decoding public key with silc_pkcs_public_key_decode, check
4019 the supported algorithm only if PKCS are registered. Affected
4020 file lib/silccrypt/silcpkcs.c. The same was done with the
4021 silc_pkcs_private_key_decode.
4023 * Fixed the SILC List routines to keep the list always in order.
4024 It used to change the list's order when traversing the list but
4025 not it preserves the order. Affected file lib/trq/silclist.h.
4027 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * Added the client library to use the SilcSocketConnection's
4030 reference counter (by silc_socket_dup) to prevent the bug that
4031 the socket object may be freed underneath async operation.
4033 * The name resolv library checking fixes in the configure.in.pre.
4036 * Created new version of the protocol drafts for future
4037 development. The -03 drafts are the ones that will be changed
4038 in the trunk now and the -02 will remain as they are.
4040 * Send list of CUMODE notifys to the router when announcing
4041 the channel users to the router. Affected file silcd/server.c.
4042 If the router receiving channel founder CUMODE for a channel
4043 that already has channel founder it will send CUMODE notify
4044 to the sender to remove the channel founder rights from the
4045 announced client. Affected file silcd/packet_receive.c.
4047 * The CUMODE notify may now use Server ID as well as the entity
4048 who changes the mode. Updated protocool specs.
4050 * Updated INSTALL and README files.
4052 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * New web pages in the http://silc.pspt.fi. The pages was
4059 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4061 * Implemented the [DenyConnectin] config section in the server.
4062 Added silc_server_config_denied_conn to check whether incoming
4063 connection is denied. Affected file silcd/serverconfig.[ch].
4065 * Do not check the ports when checking the incoming configuration
4066 data if the port is 0, meaning any. Affected file is
4067 silcd/serverconfig.c.
4069 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * Fixed buffer overflow in silc_string_compare in the file
4072 lib/silcutil/silcutil.c.
4074 * Fixed double free in silc_server_command_leave in the file
4077 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Fixed the version checking in the server. Affected file is
4082 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Fixed the configuration data fetching when accepting new
4085 connections in the server. Affected file silcd/server.c.
4087 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Added `sender_entry' argument to the function
4090 silc_server_packet_relay_to_channel so that we can check
4091 whether some destination actually belongs to the same route
4092 the sender belongs (ie, we must not resend the packet to the
4093 sender). Affected file silcd/packet_send.[ch].
4095 * Added `servername' field to the SilcClientEntry in the server
4096 to hold the name of the server where client is from. Affected
4097 file is silcd/idlist.h.
4099 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * Moved the channel message encrypting in the router betwen
4102 router connections from silc_server_channel_message to the
4103 silc_server_packet_relay_to_channel since we want to check
4104 whether we have anybody channel before encrypting anything.
4105 Affected files silcd/packet_[receive/send].c.
4107 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * Fixed the [AdminConnection] server config section to support
4110 multiple entries. Affected file silcd/serverconfig.c.
4112 * Added support into the server to check the validity of the
4113 incoming connection before executing any KE or authentication
4116 * The connection configuration is now saved to the KE and
4117 connection auth protocol contexts and not fetched anymore in
4118 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4120 * The local hosts listenning address and port is also resolved
4121 now when starting the server. We want to have the socket object
4122 to include the real address and port for the listener. Added
4123 new function silc_net_check_local_by_sock into the files
4124 lib/silcutil/silcnet.[ch].
4126 * Fixed a broadcast bug in server -> do not broadcast if we
4129 * Fixed a routing bug. Do not route broadcast packets ever.
4130 Broadcast packets must be processed always and not routed since
4131 they may be destined to some other host than yourself and thus
4132 would get routed without no good reason. Affected file is
4135 * Added function silc_server_config_is_primary_route to check
4136 whether primary router connection has been configured (a router
4137 configuration that we are initiating). If there is not, we
4138 will assume that there is only two routers in the SILC network
4139 and we will use the incoming router connection as our primary
4140 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4142 * Changed the order of the broadcasting. Broadcast _after_ the
4143 packet has been processed not before. Affected file is
4146 * Fixed a [ClientConnection] parsing bug. The port was never
4147 parsed correctly thus resulting to port 0. Affected file
4148 silcd/serverconfig.c.
4150 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4151 argument and did not set the broadcast packet flag. Affected
4152 file silcd/packet_send.c. Fixed same bug in the function
4153 silc_server_send_notify as well.
4155 * If we receive NEW_ID packet for our own ID in the server, ignore
4158 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Removed the nickname from the Private Message Payload.
4163 Updated the code and the protocol specs.
4165 * Updated protocol specs for submitting to the IETF.
4167 * Tweaked the Random Number Generator a bit. Affected file
4168 lib/silccrypt/silcrng.c. Exported a new function
4169 silc_rng_[global]_add_noise which can be used to add more
4172 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Do not parse packets with different timeout when protocol
4175 is active -> may cause problem with rekey. Affected file
4178 * When server receives signoff notify it must not create
4179 new channel key if the client is on any channels since the
4180 sender of the signoff notify will create it.
4182 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Added printing of error messages during SKE protocol from the
4185 failure packet sent by server during SKE. Affected file
4188 * Removed the client's failure_callback handling with timeout
4189 and handle it immediately when received.
4191 * The SKE library returned wrong type in SUCCESS and FAILURE
4192 packets. They must be 32 bit MSB not 16 bit MSB.
4194 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Ok, rewrote the logic of the re-key and now it seems to work.
4197 I tested it on high traffic with frequent re-keys without
4198 problems. Added hmac_receive (and renamed hmac to hmac_send)
4199 in SilcClientConnection in lib/silcclient/client.h and
4200 in SilcIDListData in silcd/idlist.h. Also, removed the
4201 SilcPacketParserContext's cipher and hmac fields as they are
4202 not needed anymore and actually caused some problems when
4203 the ciphers and hmac's changed underneath the packet parser.
4205 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * If re-key protocol is active then process the incoming packets
4208 synchronously since we must assure that icoming packets encrypted
4209 with the old key is processed before the new keys is set to
4210 use. This is true other packets than for REKEY packets.
4211 Affected file silcd/server.c. The same was done to client library
4212 as well, affected file lib/silcclient/client.c.
4214 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4216 * Fixed bug in client and server to accept the force send if
4217 the packet is send from silc_[server/client]_packet_process
4218 function. Otherwise the packets are never delivered, oops.
4220 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Disable force sending of packets when REKEY protocol is active.
4223 We must assure that no packet is sent directly when rekey is
4224 performed. All packets must be sent through packet queue.
4225 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4226 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4227 function is silc_[server/client]_packet_send_real to check
4230 * Replaced the SIM paths from example config files to
4231 /usr/local/modules. Also, make install creates now
4232 /usr/local/silc/logs directory to hold all the SILC server
4235 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Made the configure.in.pre work on Solaris. Patch by salo.
4239 * Made all ciphers compatible with non-x86 machines. Defined
4240 CBC mode macros into lib/silccrypt/ciphers_def.h.

4246 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4248 * When MAC computation fails the silc_packet_decrypt returned 0
4249 even though it was supposed to return -1. Fixed this. The
4250 affected file is lib/silccore/silcpacket.c.
4252 * Do not replace the config files in /etc/silc (in make install)
4253 if they already exist. Affected file ./Makefile.am.
4255 * Do not send re-key packets immediately but through packet queue.
4256 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4258 * Changed silc_net_check_host_by_sock to return FALSE if the
4259 IP/DNS could not be resolved. Though, it returns the IP address
4260 now even if it could not resolve it (but returns also FALSE).
4261 Affected file lib/silcutil/silcnet.[ch].
4263 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Added silc_pkcs_decode_identifier to decode the public key's
4266 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4267 Added also silc_pkcs_free_identifier. Added also new context
4268 SilcPublicKeyIdentifier.
4270 * Added -S option to the silc client. It is used to dump the
4271 contents of the specified public key file.
4273 * Changed the PKCS api to return the public key length when
4274 setting the public key.
4276 * Fixed a fatal bug in the public and private key file loading.
4277 Affected file lib/silccrypt/silcpkcs.c.
4279 * Execute the packet parsing for client with zero (0) timeout
4280 if the protocol is active. Affected file silcd/server.c.
4282 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Made the key generation options to the silcd program. Added
4285 -C option, equivalent to client's option.
4287 * Added new [ServerKeys] config section to the server. It
4288 configures the server's public and private key.
4290 * Defined generic Public Key Payload into the protocol
4291 specification to send specific type of public keys and
4294 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4295 public key or certificate.
4297 * Implemented the GETKEY command to the server and to the
4298 client library and on user interface.
4300 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Made preliminary `make install' work.
4304 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Added SilcServerRekey context into silcd/idlist.h.
4308 * Added the PFS support as defined in the specification to the
4309 SKE protocol. Affected files lib/silcske/*.c.
4311 * Added `ske_group' field to the SilcServerRekey context to hold
4312 the number of the SKE group that is used with PFS in re-key.
4313 Affected file silcd/idlist.h.
4315 * Added PFS re-key support to the server. Affected file is
4318 * Added silc_protocol_cancel to cancel execution of the next
4319 state of the protocol. Affected file is
4320 lib/silccore/silcprotocol.[ch].
4322 * Added the re-key support with and without PFS to the client
4323 library. Re-key is performed once in an hour, by default.
4325 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4326 Added silc_client_rekey_callback and silc_client_rekey_final.
4327 Affected files are lib/silcclient/protocol.[ch] and
4328 lib/silcclient/client.[ch].
4330 * Removed the `hmac_key' and `hmac_key_len' fields from the
4331 SilcClientConnection structure; not needed. Affected file is
4332 lib/silcclient/client.h.
4336 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Do not ask whether user wants to use the negotiated private key
4339 for private messages, just use it. Affected file is
4340 silc/local_command.c.
4342 * Added `send_enc_key' and `enc_key_len' fields to the
4343 SilcIDListData structure since they are needed in the re-key
4344 phase. Affected file is silcd/idlist.[ch].
4346 * Implemented the simple re-key protocol into the server.
4347 Affected files silcd/server.c and silcd/protocol.[ch]. The
4348 re-key will be performed once in an hour, by default.
4350 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4351 Added silc_server_rekey, silc_server_rekey_callback and
4352 silc_server_rekey_final.
4354 * Removed Tunneled flag from the protocol. Updated the code
4355 and the specifications.
4357 * Adde `pfs' field to the SilcIDListData to indicate whether
4358 the PFS is to be performed in the re-key. Affected file is
4361 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4363 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4364 int64 of at least the xintXX size. If void * is less that 4
4365 bytes uint32 * will be used. Defined bool as boolean.
4367 * Changed _ALL_ unsigned long and unsigned int to uint32,
4368 unsgined short to uint16 in the source tree.
4370 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4371 not handle clients that has entry->data.registered == FALSE.
4372 They are not in the network anymore. Affected file is
4375 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Implemented the sending of the SERVER_SIGNOFF notify in the
4378 server. Affected file is silcd/server.c.
4380 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4381 Added also silc_notify_payload_encode_args into the
4382 lib/silccore/silcnotify.[ch].
4384 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4385 Affected file silcd/packet_receive.c.
4387 * Implemented the SERVER_SIGNOFF notify handling in the client
4388 library. Affected file lib/silcclient/client_notify.c. Also,
4389 implemnted the printing of the SERVER_SIGNOFF info to the
4390 application. Affected file silc/client_ops.c.
4392 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4393 if the deleting was successful. Affected file silcd/idlist.[ch].
4395 * Added support for public key authentication in the connection
4396 authentication protocol in the client library. Affected file
4397 lib/silcclient/protocol.c.
4399 * Changed the server's silc_idlist_get_clients_by_* interface
4400 to support already allocated array so that new entries may be
4401 added to pre-allocated array. Affected file silcd/idlist.[ch].
4402 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4403 and command replies.
4405 * All command reply functions in the server now calls the
4406 pending command callback even if error occured. This way the
4407 error will be delivered to the client as well. Affected files
4408 silcd/command.c and silcd/command_reply.c.
4410 * Fixed INFO command to return local server's info if no server
4411 was provided. Affected file lib/silcclient/command.c.
4413 * Removed RESTART command for good. Updated the code and the
4416 * Rewrote parts of the task system. It is a bit simpler now.
4417 Removed unsued task priorities. The affected files are
4418 lib/silcutil/silctask.[ch].
4420 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Moved the USERS printing from the library to the application.
4423 Affected files lib/silcclient/command.c and silc/client_ops.c.
4425 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Added channel key re-key support. The re-key is perfomed
4430 only by the router and is done once in an hour. Added `rekey'
4431 field to the SilcChannelEntry in the server. Affected files
4432 silcd/server.c and silcd/idlist.h.
4434 * Added silc_task_unregister_by_context into the file
4435 lib/silcutil/silctask.[ch].
4437 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Added SILC_UMODE_GONE mode to indicate when the client is not
4440 present in the SILC network. Added also support to the local
4441 command AWAY that will set this mode. Added support of showing
4442 "xxx is gone" in WHOIS command. The USERS command shows the
4443 gone status as well.
4445 * Fixed setting server and router operator privileges in the
4446 server's UMODE command. Affected file silcd/command.c.
4448 * Merged the SKE KE1 and KE2 payloads into one payload. The
4449 new KE payload is equivalent to the old KE2 payload.
4451 Cleaned up the SKE Start Payload parsing. It now uses the
4452 simple buffer unformatting to do the parsing. A lot faster
4455 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4456 to the SKE that is used to indicate whether both of the SKE
4457 parties should perform authentication. By default only the
4458 responder performs authentication. By setting this flag also
4459 the initiator must do authentication. By default it is unset
4460 since in normal SKE case, client to server connection, only
4461 the responder should do authentication. When doing SKE between
4462 two clients both should perform authentication. Updated the
4463 code and the protocol specs.
4465 * A little fix to IDENTIFY command in the server. Search the
4466 client first by hash not nickname. Affected file is
4469 * Fixed the silc_client_close_connection to support closing
4470 the client to client connections wihtout deleting too much
4471 data. Affected file lib/silcclient/client.c.
4473 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4474 are received if protocol used to be active but is not anymore
4475 the application would crash due to NULL pointer dereference.
4476 Affected files silcd/server.c and lib/silcclient/client.c.
4478 * Added `hash' field to the SilcClientConnection to include
4479 the hash function negotiated in the SKE protocol.
4481 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4482 to set the channel founder authentication data. A client can
4483 claim the founder rights later by providing the authentication
4484 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4485 This way the channel founder can regain the channel founder
4486 privileges even it is left the channel. This works only on
4487 local server and the client must be connected to the same
4488 server to be able to regain the founder rights. Updated the
4489 protocol specs accordingly.
4491 Added support to the CMODE command in the client to set the
4492 founder auth data. Read the README to see how to set it.
4494 Added support to the CUMODE command to claim the founder
4495 rights. Read the README to see how to do it.
4497 Added support for the founder authentication to the Channel
4498 Entry in the server. Affected file silcd/idlist.h.
4500 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4501 server's CMODE command. Affected file silcd/command.c.
4503 * Added the following new functions into lib/silccore/silcauth.[ch]:
4504 silc_auth_get_method and silc_auth_get_data.
4506 * The server now saves the remote hosts public key to the
4507 SilcIDListData pointer. Affected file silcd/protocol.c.
4509 * The normal server now does not remove the channel entry from
4510 the cache if the founder authentication data is set. It used
4511 to remove it if the founder was the last one on the channel on
4512 the server and left the channel. The auth data is saved and
4513 if the channel is re-joined later the old entry is used with
4514 the old auth data. Affected files silcd/command_reply.c and
4517 * Removed the `pkcs' field from the SilcIDListData structure
4518 in the server; it is not used. Affected file silcd/idlist.h.
4520 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Fixed packet processing on slow links. Partial packets were
4523 never re-processed because the incoming data buffer was cleared
4524 by the application. Application must not directly clear the
4525 sock->inbuf, the packet processing routines handle it. Fixed
4526 this in client library and in server.
4528 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Fixed the WHOIS and IDENTIFY send reply function to really
4531 check whether to send list or just one entry. Affected file
4534 * Cleaned up the LEAVE command's channel key distribution. The
4535 affected file silcd/command.c.
4537 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4538 can enforce the channel mode as well. In that case the ID
4539 includes the ID of the server. The code now enforces the
4540 mode change if the router have different mode than the server.
4542 * The notify client operation with CMODE_CHANGE notify can now
4543 return NULL client_entry pointer if the CMODE was not changed
4544 by client. Application must check for this.
4546 * Added <Server ID> argument to INFO command to support server
4547 info fetching by Server ID.
4549 * Added silc_server_announce_get_channel_users to get assembled
4550 packets of channel users of the specified channel. Affected
4551 file silcd/server.[ch].
4553 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4554 was freed underneath the ID Cache.
4556 * Re-announce clients when the server received CHANNEL_CHANGE
4557 notify from the router. Affected file silcd/packet_send.c.
4559 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4562 crashed since it did not handle the fact that there is no cipher
4563 called "3" and didn't check the error condition. Now fixed.
4565 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4566 flag. It can be used to send message requests.
4568 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Implemented the RESTART command in the client.
4572 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4573 notice type messages. Added notice printing to the user
4576 * The channel keys are not re-generated if the channel's mode
4577 is PRIVKEY, ie private key on the channel exists. Affected
4578 files silcd/server.c and silcd/command.c.
4580 * Fixed a little bug in channel message delivery when channel
4581 private keys are set in the server. Affected file is
4582 silcd/packet_send.c.
4584 * Changed the setting on channel->on_channel = TRUE from the
4585 silc_client_save_channel_key to the JOIN command reply. The
4586 key payload is not received if the private channel key is set.
4587 Affected file lib/silcclient/command_reply.c and the
4588 lib/silcclient/client_channel.c.
4590 * When the CMODE_CHANGE notify is sent and the channel private
4591 key mode is removed the channel key must be re-generated in
4592 other cells as well. Added this support for the router in the
4593 silcd/packet_receive.c.
4595 * Added new local command NOTICE to send notice message on
4596 channel. Affected file silc/local_command.[ch].
4598 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Added new local command ME to the client. It is used to send
4601 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4602 some action. Affected file silc/local_command.[ch].
4604 * Changed channel_message and private_message client operations
4605 to deliver the message flags to the application. Added also
4606 the `flags' arguments to the silc_client_send_channel_message
4607 and silc_client_send_private_message functions. Affected file
4610 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Redefined the Private Message Payload to support private message
4613 keys and to support the new private message flags. Updated
4614 the protocol specs. Flags makes it possible to have for example
4615 CTCP style messages.
4617 * Added new type SilcPrivateMessagePayload and defined an API
4618 for it in the lib/silcclient/silcprivate.[ch].
4620 * Tested private message private keys successfully. Tested the
4621 private message key set, unset and list commands with the new
4624 * Redefined the Channel Message Payload to include the channel
4625 message flags (equal with private message flags) to support
4626 for example CTCP style messages.
4628 * Defined some of the message (for channel and private message)
4629 flags. Updated the protocol specs and added the flags to the
4630 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4632 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Added SilcKeyAgreementStatus type to the key agreement routines
4635 to indicate the current status and error if one occured.
4636 The status types are defined in the lib/silcclient/silcapi.h.
4638 * Added new local command KEY that is used to set and unset private
4639 keys for channels, set and unset private keys for private messages
4640 with remote clients and to send key agreement requests and
4641 negotiate the key agreement protocol with remote client. The
4642 key agreement is supported only to negotiate private message keys,
4643 it currently cannot be used to negotiate private keys for channels,
4644 as it is not convenient for that purpose.
4646 * Fixed a minor pending callback setting bug in the function
4647 silc_client_get_client_by_id_resolve, now the function works.
4648 Affected file lib/silcclient/idlist.c.
4650 * Added function silc_net_get_local_port to get local bound
4651 port by socket. Added to lib/silcutil/silcnet.[ch].
4653 * Added `sockets' and `sockets_count' fields to the SilcClient
4654 object. They hold the sockets of the listenning sockets in
4655 the client. Listenning sockets may be for example the key
4656 agreement server. Affected file lib/silcclient/client.[ch].
4657 Added functions the silc_client_add_socket and the
4658 silc_client_del_socket. They are exported to the application
4661 * Added ~./silc/clientkeys to support other client's public keys.
4663 * Renamed verify_server_key client operation to verify_public_key
4664 and added one argument to indicate the type of the connection
4665 (server, client etc.).
4667 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Added silc_server_connection_auth_request to handle the
4670 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4671 silcd/packet_receive.[ch].
4673 * Added silc_server_send_connection_auth_request into the
4674 silcd/packet_send.c to send the connection auth request packet.
4676 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4679 * Fixed the public key authentication in responder side in the
4680 server. The `auth_data' pointer includes the SilcPublicKey
4681 not the path to the public key. Affected file silcd/protocol.c.
4683 * Implemented the public key authentication in the initiator side
4684 in the server. Affected file silcd/protocol.c.
4686 * Removed the [RedirectClient] config section from the server
4687 configuration. Is not needed and I don't want to implement it.
4689 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Cleaned up the CMODE command in the server. It now works
4692 correctly and supports all the modes defined in the protocol.
4693 Affected file is silcd/command.c.
4695 * Added `hmac_name' field to the SilcChannelEntry in the server
4696 to hold the default HMAC of the channel. It can be set when
4697 creating the channel (with JOIN command). Affected files
4700 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4701 type to indicate the change of the current cipher and hmac
4702 on the channel. Client can safely ignore the <cipher> argument
4703 (if it chooses to do so) since the CHANNEL_KEY packet will
4704 force the channel key change anyway. The <hmac> argument is
4705 important since the client is responsible of setting the new
4706 HMAC and the hmac key into use.
4708 * Fixed the CMODE command in the client library as well.
4710 * Tested CMODE command in router environment successfully.
4712 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Show the version of the remote client (or server) when connecting
4715 to the server. It is logged to the log file. Affected file
4716 is silcd/protocol.c.
4718 * Fixed the KILLED notify handling in the client library. The
4719 client must be removed from all channels when receiving the
4722 Also, do not remove the client entry when giving the KILL
4723 command but when the KILLED notify is received.
4725 * Removed silc_idlist_find_client_by_nickname from the server.
4726 Not needed anymore. Affected files silcd/idlist.[ch].
4728 * Implemented the CHANNEL_CHANGE notify type handling to the
4729 server. Affected file silcd/server.c.
4733 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * Added silc_server_send_notify_invite to send the INVITE
4736 notify between routers.
4738 * Implemented the INVITE command correctly to the server.
4740 * Implemented the INVITE notify type handling in the server.
4742 * Implemented the INVITE command to the client library and on the
4745 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Added function silc_server_get_client_resolve to find the
4748 client entry by ID from all ID lists and then resolve it
4749 (using WHOIS) if it cannot be found. Affected file is
4752 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4754 * Implemented the BAN command to the client library.
4756 * The JOIN command in the server now checks the invite list
4759 * Changed the silc_command_reply_payload_encode_va and the
4760 silc_command_payload_encode_va to support that if argument is
4761 NULL it ignores and checks the next argument. Affected file
4762 lib/silccore/silccommand.c.
4764 * Added silc_server_send_notify_ban to send the BAN notify
4765 type between routers.
4767 * Chaned the silc_notify_payload_encode to support that if
4768 argument is NULL it ignores and checks the next argument.
4769 Affected file lib/silccore/silcnotify.c.
4771 * Tested ban lists in router environment successfully.
4773 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Implemented BAN command to the server, in silcd/command.[ch].
4777 * Removed the BAN and INVITE_LIST modes from the CMODE command
4780 * Added function silc_string_match to regex match two strings.
4781 Affected files lib/silcutil/silcutil.[ch].
4783 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Redefined parts of the SilcChannelEntry in the server to support
4786 the new ban and invite lists.
4788 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Redefined the INVITE command. The same command can be used to
4791 invite individuals to the channel but also to manage the invite
4792 list of the channel (to add to and remove from the invite list).
4793 Updated the protocol specs.
4795 * Added new command SILC_COMMAND_BAN that can be used to manage
4796 the ban list of the channel. Updated the protocol specs.
4798 * Removed the channel modes: the SILC_CMODE_BAN and the
4799 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4800 in the CMODE command. The equivalent features are now available
4801 using INVITE and BAN commands. Updated the protocol specs.
4803 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4804 in the network about change in the current ban list. The notify
4805 type is not used by the client.
4807 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4808 support the invite lists.
4810 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4812 * Added new function silc_string_regexify that converts string
4813 including wildcard characters into regex string that can
4814 be used by the GNU regex library. Added into the file
4815 lib/silcutil/silcutil.[ch].
4817 Added silc_string_regex_combine to combine to regex strings
4818 into one so that they can be used as one regex string by
4819 the GNU regex library. Added into the file
4820 lib/silcutil/silcutil.[ch].
4822 Added silc_string_regex_match to match two strings. It returns
4823 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4825 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4827 * Imported GNU regex to the soruce tree into lib/contrib.
4828 Fixed some compiler warning from the regex.c.
4830 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Fixed MOTD command in the server to work in router environment.
4834 * Fixed the MOTD command in the client library to support
4835 the server argument in the command.
4837 * Added `nickname_len' argument to the silc_idlist_add_client
4838 in the server, as the `nickname' argument may be binary data
4841 * Added silc_idlist_get_channels to return all channels from
4844 * Implemented LIST command to the server. Affected file is
4847 * Implemented the LIST command to the client library and on the
4850 * Added [<user count>] argument to the LIST command reply.
4851 With private channels the user count is not shown.
4853 * Updated TODO and README.
4855 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * The client entry's data.registered must be TRUE even with
4858 global client entry on global client list. The data.registered
4859 is used to check whether the client is anymore in the network,
4860 for example with WHOWAS command so it must be valid.
4862 * Fixed the WHOWAS command in the server. It now actually works
4863 in router environment. Added function into silcd/command_reply.c
4864 silc_server_command_reply_whowas_save.
4866 * Added silc_idlist_purge function to the silcd/idlist.c
4867 to periodically purge the ID Cache.
4869 * Fixed INFO command in the server. It works now in router
4870 environment. Added <server name> argument to the INFO command
4871 reply. Updated the protocol specs.
4873 * Fixed minor bug in silc_idcache_purge to not purge if the
4874 expire value is zero.
4876 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4877 they were buggy because of the WHOWAS information.
4879 * Fixed local command MSG to handle the async resolving of
4880 the remote client properly. It used to fail the first MSG.
4881 Affected file silc/local_command.c.
4883 * Added `data_len' field to SilcIDCache context.
4885 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4887 * Update TODO. Todo in commands in the server.
4889 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4892 used by routers as broadcast packet to inform other routers
4893 about the changed user mode.
4895 Implemented the notify handling in the server. Affected file is
4896 silcd/packet_receive.c. Added the function
4897 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4899 * Added new generic Channel Payload and deprecated the New Channel
4900 Payload. The New Channel Payload is now the generic Channel
4903 * Added new argument `mode' to the silc_server_send_new_channel
4904 as it is required in the Channel Payload now.
4906 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4907 and created a new and real SilChannelPayload to represent the
4908 new generic Channel Payload. Implemented the encode/decode
4909 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4911 * Added silc_server_get_client_channel_list to return the list
4912 of channels the client has joined for WHOIS command reply.
4913 Affected file silcd/server.[ch].
4915 * Implemented the channel list sending in the WHOIS command reply
4916 in server and in the client.
4918 Implemented the channel list displaying on the user interface
4919 as well. Affected file silc/client_ops.c.
4921 * Added silc_channel_payload_parse_list to parse list of Channel
4922 Payloads. It returns SilcDList list of SilcChannelPayloads.
4923 Client for example can use this function to parse the list of
4924 channels it receives in the WHOIS command reply. The caller
4925 must free the list by calling silc_channel_payload_list_free.
4926 Affected files lib/silccore/silcchannel.[ch].
4928 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4930 * Added one new argument <user mode> to the WHOIS command reply
4931 to return the mode of the user in SILC. Updated the protocol
4934 Implemented it to the server and client.
4936 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4938 * Fixed the mode printing on the user interface on joining.
4939 Affected file silc/client_ops.c.
4941 * Implemented the UMODE command and user modes in general to the
4942 client library and to the user interface.
4944 * Implemented the UMODE command to the server.
4946 * The server now sends UNKNOWN_COMMAND error status if client sends
4947 unknown command. Affected file silcd/command.c.
4949 * All server commands now handle the command identifier the right
4950 way when sending the command reply to the client. The client can
4951 use to identify the command replies with the identifier.
4953 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Added silc_server_get_client_route to resolve the route to
4956 the client indicated by the client ID. Affected file is
4959 * Added silc_server_relay_packet as general function to relay
4960 packet to arbitrary destination. This deprecates functions
4961 like _send_private_message_key, _relay_notify etc. Affected
4962 file is silcd/packet_send.[ch].
4964 Removed silc_server_send_key_agreement,
4965 silc_server_send_private_message_key and
4966 silc_server_packet_relay_notify functions from the file
4967 silcd/packet_send.[ch].
4971 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4972 server. Affected file silcd/packet_receive.[ch].
4974 * Implemented the KILL command to the client. Implemented the
4975 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4976 Affected files lib/silcclient/command[_reply].c and
4977 lib/silcclient/client_notify.c. Implemented the KILL notify
4978 printing in the user inteface.
4980 * Fixed a lot silc_parse_nick memory leaks from the client
4981 library in the file lib/silcclient/command.c.
4983 * Changed the silc_server_send_notify_on_channels's `sender'
4984 argument from SilcSocketConnection to SilcClientEntry to
4985 check the sender as entry and not as connection object and not
4986 to send to the client provided as argument. The affected file
4987 is silcd/packet_send.[ch].
4989 * The notify packets that are destined directly to the client used
4990 to not to be processed by the server. Now changed that and the
4991 server processes all notify packets. After relaying the packet
4992 to the client the notify packet is processed in the server.
4994 * The silc_server_free_client_data now checks whether there is
4995 pending outgoing traffic for the client and purges the data to
4996 the network before removing the client entry.
4998 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5000 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5001 an client is killed from the SILC Network. Updated the protocol
5004 Added new function silc_server_send_notify_killed to the
5005 silcd/packet_send.[ch].
5007 * Added function silc_server_packet_relay_notify to relay notify
5008 packets that are destined directly to a client. In this case
5009 the server does not process the notify packets but merely relays
5010 it to the client. Affected file silcd/packet_send.[ch].
5012 Added also silc_server_packet_process_relay_notify to check
5013 whereto relay the notify. Affected file is
5014 silcd/packet_receive.[ch].
5016 * Implemented the KILL command to the server.
5020 * Added the backup schema desgined last fall to the protocol
5021 specs for everyone to see. The specification is in the
5022 *-spec-xx.txt draft and the packet type definitions for the
5023 backup routers is in *-pp-xx.txt draft. Thusly, added also
5024 new packet type SILC_PACKET_CELL_ROUTERS.
5026 * A big security problem in the implementation discovered. The
5027 signoff of an client did not cause new channel key generation
5028 which it of course should've done. The channel keys must be
5029 always re-generated when client leaves (or signoffs) the channel.
5030 The silc_server_remove_from_channels funtion now handles
5031 the channel key re-generation.
5033 * Added `sender' argument to the silc_server_send_notify_on_channels
5034 to not to send the client provided as argument. Affected file
5035 silcd/packet_send.[ch].
5037 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Implemented OPER and SILCOPER commands into the server and
5042 * Added silc_auth_verify and silc_auth_verify_data to verify
5043 the authentication directly from the authentication payload.
5044 It supports verifying both passphrase and public key based
5045 authentication. Affected file lib/silccore/silcauth.[ch].
5047 * Added `hash' field to the SilcIDListData structure. It is the
5048 hash negotiated in the SKE protocol. Affected file is
5051 * Slight redesigning of the SilcAuthPayload handling routines.
5052 Do not send SilcPKCS but SilcPublicKey as argument.
5054 * Implemented the public key authentication support to the
5055 serverconfig. The public key is loaded from the provided path
5056 and saved as authentication data to void * pointer. Thus,
5057 changed the unsigned char *auth_data to void *auth_data;
5059 * Fixed SHUTDOWN command to send the reply before the server
5060 is shutdown. :) Affected file silcd/command.c.
5062 * Fixed fatal bug in CONNECT command. The hostname was invalid
5063 memory and server crashed. Affected file silcd/command.c.
5065 * Fixed fatal bug in CLOSE command. The server_entry became
5066 invalid but was referenced later in the command. Affected file
5069 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5071 * Fixed fatal bug in failure packet handling. Server ignored
5072 the failure and thus crashed when it came.
5076 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5078 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5079 that the command may be executed only once in (about) 2 seconds.
5080 The old SILC_CF_LAG flag is same but allows command bursts up
5081 to five before limiting.
5083 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5084 server code. Various commands now includes the CF_LAG_STRICT
5085 flag to disallow any kind of miss-use of the command.
5087 * Fixed the silc_buffer_unformat to not to allocate any data
5088 if the length of the data is zero. It used to allocate the
5089 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5091 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Changed the format of AdminConnection configuration section
5094 in the server. Added username of the admin to the format.
5095 Affected files silcd/serverconfig.[ch].
5097 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5098 to return admin configuration data by host, username and/or
5101 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Implemented WHOWAS command to the server. Added the functions:
5105 silc_server_command_whowas_parse,
5106 silc_server_command_whowas_send_reply,
5107 silc_server_command_whowas_from_client and
5108 silc_server_command_whowas_from_server
5110 * Added <Client ID> argument to the WHOWAS command reply. Updated
5111 the protocol specs accordingly.
5113 * Implemented WHOWAS command and command_reply to the client
5116 Implemented the WHOWAS printing on the user interface.
5118 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5120 * Added new argument to the WHOWAS command reply, the real name.
5121 It is an optional argument. Updated the protocol specs.
5123 * Added SilcIDCacheDestructor callback that is registered when
5124 the SilcIDCache is allocated. The callback is called when
5125 an cache entry in the ID Cache expires, or is purged from the
5126 cache. Added into lib/silccore/idcache.[ch].
5128 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5129 to destruct the client entries when the cache entry expires.
5130 Other ID Cache's in server and in the client library ignores
5133 * If the ID Cache entry's `expire' field is zero then the entry
5134 never expires. Added boolean `expire' argument to the
5135 silc_idcache_add function in the lib/silccore/idcache.[ch].
5136 If it is TRUE the default expiry value is used.
5138 * Added silc_server_free_client_data_timeout that is registered
5139 when client disconnects. By default for 5 minutes we preserve
5140 the client entry for history - for WHOWAS command.
5142 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Added support to the server to enforce that commands are not
5145 executed more than once in 2 seconds. If server receives
5146 commands from client more frequently, timeout is registered
5147 to process the commands. Affected file silcd/command.c.
5148 Added new function silc_server_command_process_timeout.
5150 * Changed NICK_NOTIFY handling in client library to check that
5151 if the client's nickname was changed, so there is no need to
5152 resolve anything from the server.
5154 * Removed error printing from the WHOIS and IDENTIFY commands.
5155 If error occurs then it is ignored silently in the client library.
5156 The application, however, may map the received error to
5157 human readable error string. The application currently maps
5158 the NO_SUCH_NICKNAME error to string.
5160 * Made the command status message public to the application. Moved
5161 them from lib/silcclient/command_reply.c to
5162 lib/silcclient/command_reply.h. The application can map the
5163 received command status to the string with the
5164 silc_client_command_status_message function.
5166 * Added check to the server to check that client's ID is same
5167 as the Source ID in the packet the client sent. They must
5170 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Added dist-bzip hook to the Makefile.am to make bzip2
5173 compressed distributions.
5175 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * Server now enforces the maximum length for the nickname and
5178 the channel as protocol specification dictates. 128 bytes for
5179 nickname and 256 bytes for channel name.
5181 * Moved the WHOIS printing to the application. The client libary
5182 does not print out the WHOIS information anymore, the application
5183 must do it. Renamed silc_client_command_reply_whois_print to
5184 the silc_client_command_reply_whois_save.
5186 The client's idle time is also sent to the application now, and
5187 the idle is shown on screen.
5189 * Added silc_client_command_reply_identify_save to save the
5190 received IDENTIFY entries.
5192 * Do not check for channel private keys in message sending and
5193 reception if the channel does not have the PRIVKEY mode set.
5194 Affected file lib/silclient/client_channel.c.
5196 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5198 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5199 just surfaced after chaning the JOIN procedure.
5201 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5203 * Added silc_client_get_clients_by_list to get client entries
5204 from Client ID list, that is returned for example by JOIN
5205 and USERS command replies. The application should use this
5206 function for example when JOIN command reply is received to
5207 resolve the clients already on the channel (library does not
5208 do that anymore as USERS command reply is not used in the JOIN
5209 procedure anymore). Affected files lib/silcclient/silcapi.h and
5210 lib/silcclient/idlist.c.
5212 * JOIN command reply and USERS command reply returns now SilcBuffer
5213 pointers instead of unsigned char pointers when returning
5214 the client list and mode list.
5216 * Added <Client ID> argument to the JOIN command reply, mainly
5217 for the server to identify for which client the command was
5218 originally sent. Updated protocol specs accordingly.
5220 * Added SilcDlist private_key pointer to the SilcChannelEntry
5221 in the client to support the channel private keys. Affected
5222 file is lib/silcclient/idlist.h.
5224 * Added SilcChannelPrivateKey argument to the function
5225 silc_client_send_channel_message so that application can choose
5226 to use specific private ke if it wants to. If it is not provided,
5227 the normal channel key is used, unless private keys are set.
5228 In this case the first (key that was added first) is used
5229 as the encryption key.
5231 * Implemented the support for channel private key handling.
5232 Implemented the following functions:
5234 silc_client_add_channel_private_key,
5235 silc_client_del_channel_private_keys,
5236 silc_client_del_channel_private_key,
5237 silc_client_list_channel_private_keys and
5238 silc_client_free_channel_private_keys
5240 Affected file lib/silcclient/client_channel.c.
5242 * Added the support for the private keys in the channel message
5243 sending and encryption and in the message reception and
5244 decryption. Affected funtions are
5245 silc_client_send_channel_message and silc_client_channel_message.
5247 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Added SKE's key verify callback to the client library's
5250 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5252 * Removed the statement that server (or router) must send USERS
5253 command reply when joining to the channel so that the client
5254 knows who are on the channel. Instead, the client list and
5255 client's mode list is now sent in the JOIN command reply to the
5256 client who joined channel. This is better solution.
5258 * Added function silc_server_get_users_on_channel and function
5259 silc_server_save_users_on_channel to the silcd/server.[ch].
5261 * Removed function silc_server_command_send_users from the
5264 * Do not show topic on the client library anymore. The topic is
5265 sent in the command reply notify to the application and the
5266 application must show the topic now.
5268 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Added client searching by nickname hash into the IDENTIFY and
5271 WHOIS commands in the server as they were clearly missing from
5272 them. Affected file is silcd/command.c.
5274 * Fixed a bug in private message receiving in the client library.
5275 The remote ID was freed and it wasn't supposed, now it is
5278 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Minor fix to the channel payload; allocate the data area, as it
5281 needs to be of specific length.
5283 * If the key agreement port is zero then the operating
5284 system will define the bound port. Affected files are
5285 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5287 * Added new function silc_channel_payload_decrypt into the file
5288 lib/silccore/silcchannel.[ch].
5290 * Moved the channel message etc, check from silc_packet_decrypt
5291 to applications. The library calls now a generic
5292 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5293 when the packet is either normal or special. This was done to
5294 allow more wide range of checking that was not allowed when
5295 the code was in library. Now applications can do virtually any
5296 checks to the packet and return to the library the decision how
5297 the packet should be processed. Affected files are
5298 lib/silccore/silcpacket.[ch].
5300 Added silc_server_packet_decrypt_check to the server and
5301 silc_client_packet_decrypt_check to the client library.
5303 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5304 to send with specified source and destination information.
5306 * Channel message delivery between routers was broken after the
5307 channel key distribution was fixed earlier. The channel key
5308 was used be to distributed to other routers as well which is not
5309 allowed by the protocol. Now this is fixed and channel keys
5310 really are cell specific and the channel message delivery between
5311 routers comply with the protocol specification.
5313 * Fixed various commands in server to check also the global list
5314 for the channel entry and not just the local list. The affected
5315 file silcd/command.c.
5317 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Added assert()s to buffer formatting and unformatting routines
5320 to assert (if --enable-debug) when error occurs. Affected
5321 file: lib/silcutil/silcbuffmt.c.
5323 * Changed to auto-reconnect to check whether the remote host is
5324 router and register the re-connect timeout if it is. It used
5325 to check that whether we are normal server, but router must do
5326 auto-reconnect with another router as well. Affected file
5329 * Removed the [<key len>] option from CMODE command as the cipher
5330 name decides the key length, nowadays. See the defined ciphers
5331 from the protocol specification.
5333 * Added [<hmac>] option to the CMODE command to define the HMAC
5334 for the channel. Added SILC_CMODE_HMAC channel mode.
5336 * Added [<hmac>] option for the JOIN command so that user can
5337 select which HMAC is used to compute the MACs of the channel
5340 * Added Hmac field to the Channel Message Payload. The integrity
5341 of plaintext channel messages are now protected by computing
5342 MAC of the message and attaching the MAC to the payload. The
5343 MAC is encrypted. Now, it is clear that this causes some
5344 overhead to the size of the packet but rationale for this is that
5345 now the receiver can verify whether the channel message decrypted
5346 correctly and also when private keys are set for the channel the
5347 receiver can decrypt the packet with several keys and check from
5348 the MAC which key decrypted the message correctly.
5350 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5351 lib/silccrypt/silccipher.[ch].
5353 * Added silc_hash_len to return the digest length into the
5354 lib/silcrypt/silchash.[ch].
5356 * Rewrote parts of Silc Channel Payload interface in the
5357 lib/silccore/silcchannel.[ch]. The encode function now also
5358 encrypts the packet and parse function decrypts it.
5360 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5362 * Fixed a minor formatting bug in the SKE's key material processing.
5363 It actually might have processed the keys wrong way resulting
5366 * Redefined the mandatory HMAC algorithms and added new algorithms.
5367 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5368 and hmac-md5 truncated to 96 bits. The mandatory is now
5369 hmac-sha1-96. Rest are optional (including the one that used
5370 to be mandatory). Rationale for this is that the truncated HMAC
5371 length is sufficient from security point of view and can actually
5372 make the attack against the HMAC harder. Also, the truncated
5373 HMAC causes less overhead to the packets. See the RFC2104 for
5376 * Added new [hmac] configuration section. The SKE used to use
5377 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5378 is of course wrong. The official names that must be proposed in
5379 the SKE are the ones defined in the protocol specification
5380 (hmac-sha1-96 for example). The user can configure any hmac
5381 using any hash function configured in the [hash] section. At
5382 least, the mandatory must be configured.
5384 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5386 * Added HMAC list to the SKE proposal list. It has now both
5387 hash algorithm list and HMAC list. This makes the protocol
5388 incompatible with previous versions. The SKE now seems to work
5389 the way it is supposed to work, for the first time actually.
5391 * Defined plain Hash algorithms to the protocol specification.
5394 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Implemented support for key agreement packets into the server.
5397 Added functions silc_server_key_agreement and
5398 silc_server_send_key_agreement. Other than these functions,
5399 server has nothing to do with this packet.
5401 * Added support for private message key packets into the server.
5402 Added functions silc_server_private_message_key and
5403 silc_server_send_private_message_key.
5407 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5408 called in the protocol's final callback instead in the END
5409 protocol state. This makes a little more sense and in the same
5410 time in client we can use the same protocol routines for normal
5411 key exchange and to key agreement packet handling as well.
5413 * Added to both client's and server's KE protocol context the
5414 SilcSKEKeyMaterial pointer to save the key material. We will
5415 bring the key material to the protocol's final callback by doing
5416 this. The final callback must free the key material.
5418 * Added SKE's packet_send callback into client's KE protocol
5419 context so that the caller can choose what packet sending function
5420 is used. This way we can use different packet sending when
5421 doing normal SKE when doing key agreement packet handling (in
5422 the key agreement packet handling we do not want to encrypt
5425 * Implemented the responder side of the key agreement routines
5426 in the client. The client can now bind to specified port and
5427 accept incoming key negotiation. The key material is passed
5428 to the application after the protocol is over.
5430 * Implemented the processing of incoming Key Agreement packet
5431 in the client. Added function silc_client_key_agreement to
5434 * Implemented the intiator side of the key agreement routines
5435 in the client. The client can now initiate key agreement with
5436 another remote client. The key material is passed to the
5437 application after the protocol is over.
5439 * Created client_keyagr.c to include all the key agreement
5442 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5443 SILC_TASK_CALLBACK except that it is not static.
5445 * Created client_notify.c and moved the Notify packet handling
5446 from the client.[ch] into that file.
5448 * Created client_prvmsg.c and moved all private message and
5449 private message key routines from the client.[ch] into that file.
5451 * Create client_channel.c and moved all channel message and
5452 channel private key routines from the client.[ch] into that file.
5454 * Changed silc_client_get_client_by_id_resolve to resolve with
5455 WHOIS command instead of IDENTIFY command, in the file
5456 lib/silclient/idlist.c.
5458 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Implemented the SKE's responder side to the Client library.
5462 * When FAILURE is received to the protocol do not trust it
5463 blindly. Register a timeout to wait whether the remote closes
5464 the connection as it should do it, only after that process the
5465 actual failure. This was changed to both client and server.
5467 * Added client_internal.h to include some of the structures
5468 there instead of client.h in lib/silcclient/.
5470 * Added function silc_task_unregister_by_callback to unregister
5471 timeouts by the callback function.
5473 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * Some "Incomplete WHOIS info" errors has been appearing on the
5476 log files. Took away the entry->userinfo check from WHOIS
5477 reply sending. The entry->userinfo is now " " if client did not
5478 provide one. I thought this was fixed earlier but something
5479 is wrong still. Let's see if the error still appears.
5481 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Fixed a minor bug in the login when the channel key is
5484 re-generated in the server. It used to generate the key in
5485 wrong order and thus caused problems in the channel traffic.
5487 * Fixed a minor bug in channel key distsribution after
5488 KICK command. The key was not sent to the router even though
5491 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Added silc_ske_process_key_material_data as generic routine
5494 to process any key material as the SILC protocol dictates. The
5495 function is used by the actual SKE library but can be used by
5496 applications as well. This relates to the private message keys
5497 and the channel private keys since they must be processed the
5498 same way the normal SILC session keys. The protocol dictates
5499 this. Affected files: lib/silcske/silcske.[ch].
5501 Added also silc_ske_free_key_material to free the
5502 SilcSKEKeyMaterial structure.
5504 * Defined silc_cipher_set_key function to set the key for
5505 cipher without using the object's method function. The affected
5506 files: lib/silccrypt/silccipher.[ch].
5508 * Implemented silc silc_client_add_private_message_key,
5509 silc_client_add_private_message_key_ske,
5510 silc_client_del_private_message_key,
5511 silc_client_list_private_message_keys and
5512 silc_client_free_private_message_keys functions in the
5515 Added functions silc_client_send_private_message_key to send
5516 the Private Message Key payload and silc_client_private_message_key
5517 to handle incoming Private Message Key payload.
5519 * Added Cipher field to the Private Message Key payload to set
5520 the cipher to be used. If ignored, the default cipher defined
5521 in the SILC protocol (aes-256-cbc) is used.
5523 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Removed lib/silcclient/ops.h file.
5527 Redefined parts of the SILC Client Library API. Created new
5528 file silcapi.h that deprecates the ops.h file and defines the
5529 published Client Library API. Defined also private message key
5530 API and channel private key API into the file.
5532 This is the file that the application must include from the
5533 SILC Client Library. Other files need not be included by
5534 the application anymore.
5536 * Added new key_agreement client operation callback and also
5537 defined the Key Agreement library API for the application.
5539 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5541 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5542 is used by clients to request key negotiation between another
5543 client in the SILC network. If the negotiation is started it
5544 is performed using the SKE protocol. The result of the
5545 negotiation, the secret key material, can be used for example
5546 as private message key.
5548 Implemented the Key Agreement payload into the files
5549 lib/silccore/silauth.[ch].
5551 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Redefined ciphers for the SILC protocol. Added some new ciphers
5554 and defined the key lengths for the algorithms. Changed the
5555 code accordingly. The default key length is now 256 bits.
5557 * Fixed SKE key distribution function silc_ske_process_key_material
5558 when the key length is more than 128 bits. The default key
5559 length in SILC is now 256 bits.
5561 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5562 to indicate unsupported algorithm.
5564 * Renamed rijndael.c to aes.c and all functions as well.
5566 * Fixed a long standing channel key setting bug in client library.
5567 Weird that it has never surfaced before.
5569 * Fixed bug in channel deletion. If the entire channel is removed
5570 then it must also delete the references of the channel entry
5571 from the client's channel list as the client's channel entry and
5572 the channel's client entry share same memory.
5574 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5576 * Implemented CONNECT and SHUTDOWN commands in the client.
5578 * Implemented CLOSE command to the client.
5580 * Added the function silc_idlist_find_server_by_name into the
5581 files silcd/idlist.[ch].
5583 Added the function silc_idlist_find_server_by_conn into the
5584 files silcd/idlist.[ch].
5586 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * DIE command was renamed to SHUTDOWN. Updated the both code
5591 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5592 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5594 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5597 * Added function silc_server_create_connection function to create
5598 connection to remote router. My server implementation actually
5599 does not allow router to connect to normal server (it expects
5600 that normal server always initiates the connection to the router)
5601 so the CONNECT command is only good for connecting to another
5604 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5607 or some other client was kicked from the channel.
5609 Implemented the handling of the notify type to both client
5612 Implemented silc_server_send_notify_kicked to send the KICKED
5613 notify. It is used to send it to the server's primary router.
5615 * Implemented the KICK command into server and client.
5617 * Added `query' argument to the silc_idlist_get_client function
5618 to indicate whether to query the client from server or not if
5621 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5622 to indicate that the client is not channel founder.
5626 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Removed the rng context from SilcPacketContext structure and
5629 changed that the packet routine uses the Global RNG API.
5631 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Added support for quit message that client can "leave" on the
5634 channel when it quits the SILC. It is ditributed inside the
5635 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5637 Added silc_server_free_client_data that will take the
5638 signoff message as argument.
5640 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5642 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5644 * Updated parts of the protocol specification to keep it up
5647 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5650 payloads in one packet.
5652 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5653 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5654 use now the new List flag.
5656 * Also deprecated the following packet types: REPLACE_ID,
5657 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5659 * Added list support for Notify packet in server.
5661 * Added silc_server_send_notify_channel_change to send the
5662 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5663 the silc_server_send_replace_id.
5665 * Added silc_server_send_notify_nick_change to send the
5666 NICK_CHANGE notify type. Deprecates the function
5667 silc_server_send_replace_id.
5669 * Added silc_server_send_notify_join to send the JOIN notify type.
5670 Deprecates the function silc_server_send_new_channel_user.
5672 * Added silc_server_send_notify_leave to send LEAVE notify type.
5673 Deprecates the function silc_server_send_remove_channel_user.
5675 * Added silc_server_send_notify_cmode and
5676 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5677 types. Deprecates the silc_server_send_set_mode function.
5679 * Added SERVER_SIGNOFF notify type to indicate that server has
5680 quit. This means that all clients on the channel from that
5681 server will drop. This can be also used when netsplit happens.
5683 Deprecated REMOVE_ID packet type since it is not needed anymore
5686 Added silc_server_send_notify_server_signoff to send the
5687 SERVER_SIGNOFF notify type. Deprecates the function
5688 silc_server_send_remove_id.
5690 Added also silc_server_send_notify_signoff to send the
5691 SIGNOFF notify type.
5693 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5694 SILC protocol from this day on. Changed the protocol
5695 specification as well.
5697 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5698 notify type. It is used between routers to notify about
5699 topic changes on a channel.
5701 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5704 * Partly updated the protocol specification to comply with the
5705 changes now made. It is still though a bit outdated.
5707 * The JOIN notify type now takes one extra argument <Channel ID>.
5708 The packet used to be destined to the channel but now the
5709 JOIN type may be sent as list thus it is impossible to
5710 destine it to any specific channel. By adding this argument
5711 it is again possible.
5713 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * Added CREDITS file. The CHANGES and CREDITS file will appear
5716 in the distribution as well.
5718 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5721 types in the server's silcd/packet_receive.c.
5723 * Implemented CMODE and CUMODE to work in router environment.
5725 * Fixed minor encoding and decoding buglet from the
5726 lib/silccore/silcmode.c.
5728 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5731 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5733 * Changed all SilcConfigServer* and silc_config_server* to
5734 SilcServerConfig* and silc_server_config*, respectively.
5737 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Associated the ID (client or server ID) to the Authentication
5740 Payload to avoid any possibility of forging. Updated the
5741 protocol specification and the code accordingly.
5743 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5745 * The RSA key length is now save to the RsaKey context in the
5746 key generation process in lib/silccrypt/rsa.c. The key length
5747 is now used to figure out the maximum size of the block allowed
5748 to be encrypted/signed.
5750 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5751 is equivalent to the silc_mp_mp2bin but does not allocate any
5754 * Changed silc_mp_mp2bin API to take length argument. If it is
5755 non-zero then the buffer is allocated that large. If zero, then
5756 the size is approximated using silc_mp_sizeinbase, which however
5759 * Created Global RNG API which is global RNG that application can
5760 initialize. After initializing, any routine anywhere in the
5761 code (including library) can use RNG without allocating a new
5762 RNG object. This was done to allow this sort of use of the
5763 RNG in code that has no chance to allocate RNG object. All
5764 applications currently allocate this and many routines in the
5765 library use this. Affected file lib/silccrypt/silcrng.[ch].
5767 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5768 it to use the Global RNG API.
5770 * Defined Authentication Payload into protocol specification that
5771 is used during SILC session to authenticate entities. It is
5772 used for example by client to authenticate itself to the server
5773 to obtain server operator privileges.
5775 Implemented this payload into the lib/silccore/silcauth.[ch].
5776 Implemented also routines for public key based authentication
5777 as the new protocol specification dictates.
5779 Moved definitions of different authentication methods from
5780 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5782 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5783 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5784 silc_pkcs_verify_with_hash functions into the file
5785 lib/silccrypt/silcpkcs.[ch].
5787 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5789 * The client entry's userinfo pointer must be always valid.
5790 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5791 will fail since it requires the userinfo. Now, the userinfo
5792 is allocated as "" if actual userinfo does not exist. Actually,
5793 it must exist and it is totally Ok to drop client connections
5794 that does not announce the userinfo. However, we will make
5795 this workaround for now.
5797 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5798 to return the remote port by socket.
5800 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5803 SILC_SERVER_PENDING_EXEC and added an new macro
5804 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5805 data or when error occurs while processing the pending command.
5807 Added new argument `destructor' into silc_server_command_pending
5808 and to the SilcServerCommandPending object. This destructor is
5809 now called after calling the pending callback or if error occurs
5810 immediately. If error occurs the actual pending callback won't
5811 be called at all - only the destructor. The destructor may be
5812 NULL if destructor is not needed.
5814 All this applies for client library code as well. Similar
5815 changes were made there as well for the pending commands.
5817 In the client, the application must now allocate the
5818 SilcClientCommandContext with the silc_client_command_alloc
5821 * Added reference counter to the SilcServerCommandContext. Added
5822 function silc_server_command_alloc and silc_server_command_dup
5825 Same type of functions added to the client library for the same
5828 * Removed the cmd_ident from IDListData away since it is now
5829 global for all connections. It is the command identifier used
5830 in command sending and with pending commands. The affected file
5833 * Added reference counter to the SilcSocketConnection objecet to
5834 indicate the usage count of the object. The object won't be
5835 freed untill the reference counter hits zero. Currently only
5836 server uses this, and client ignores it. The client must be
5837 set to use this too later. The affected files are
5838 lib/silccore/silcsockconn.[ch]. Added also the function
5839 silc_socket_dup to increase the reference counter.
5841 This was mainly added because it is possible that the socket
5842 is removed underneath of pending command or other async
5843 operation. Now it won't be free'd and proper DISCONNECTING
5844 flags, etc. can be set to avoid sending data to connection that
5845 is not valid anymore.
5847 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5848 the connection. After that it sets SILC_SET_DISCONNECTED.
5849 It is, however, possible that the socket data is not still freed.
5850 The silc_server_packet_process now checks that data is not
5851 read or written to connection that is DISCONNECTED. The socket
5852 get's freed when the reference counter hits zero.
5854 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5856 * Changed the client operation API: channel_message operation's
5857 `sender' is now the client entry of the sender, not the nickname
5858 and the `channel' is the channel entry, not the channel name.
5860 In the private_message operation the `sender' is now also the
5861 client entry of the sender not the nickname.
5863 Affected file is lib/silcclient/ops.h and all applications
5864 using the client operations.
5866 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * Moved the calling of ops->connect() from connect_to_server_final
5869 into receive_new_id functin since that is the point when the
5870 client is actually allowed to send traffic to network. The
5871 affected file is lib/silcclient/client.c.
5873 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5876 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5877 (if needs broadcasting) instead of broadcasting the packets one
5878 by one which would make a burst in the network traffic.
5880 * Added `broadcast' argument to the functions in silcd/server.[ch]
5881 silc_server_create_new_channel[_with_id] to indicate whether
5882 to send New Channel packet to primary router.
5884 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Added new function into the silcd/server.[ch] files:
5887 silc_server_create_new_channel_with_id to create new channel with
5888 already existing Channel ID.
5890 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5891 lib/silccore/silcpacket.h. This packet is used t send list of
5892 Set Mode payloads inside one packet. Server uses this to set
5893 the modes for the channels and clients on those channels, that it
5894 announced to the router when it connected to it. The protocol
5895 specification has been updated accordingly.
5897 * The silc_server_new_channel did not handle the packet coming
5898 from normal server as it normally does not send that. However,
5899 when it announces its channels it does send it. Implemented
5900 the support for that.
5902 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5903 into the file lib/silccore/id.h.
5905 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5907 * Fixed memory leaks in the functions silc_idlist_del_client,
5908 silc_idlist_del_channel and silc_idlist_del_server in the file
5909 silcd/idlist.c. All of those leaked like a sieve.
5911 * Fixed some small memory leaks in the client's function
5912 silc_client_notify_by_server.
5914 * Added functions into silcd/server.c: silc_server_announce_clients,
5915 silc_server_announce_channels and silc_server_announce_server.
5916 These functions are used by normal and router server to announce
5917 to its primary router about clients, channels and servers (when
5918 router) that we own. This is done after we've connected to the
5921 These functions effectively implements the following packet types:
5922 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5923 and SILC_PACKET_NEW_ID_LIST.
5925 * Added new functions into the silcd/packet_receive.[ch]:
5926 silc_server_new_id_list, silc_server_new_channel_list and
5927 silc_server_new_channel_user_list to handle the incoming
5928 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5930 * Added support of changing Channel ID in the function
5931 silc_server_replace_id. If the server that announces a channel
5932 to the router already exists in the router (with same name but
5933 with different Channel ID), router is responsible to send
5934 Replace ID packet to the server and force the server to change
5935 the Channel ID to the one router has.
5937 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5938 client that the Channel ID has been changed by the router. The
5939 normal server sends this to the client. Client must start using
5940 the new Channel ID as the channel's ID.
5942 Implemented handling of this new type into lib/silcclient/client.c
5943 into the function silc_client_notify_by_server.
5945 * Added new function silc_idlist_replace_channel_id into the files
5946 silcd/idlist.[ch] to replace the Channel ID.
5948 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Call silc_server_command_identify_check always when processing
5951 the IDENTIFY command in silcd/command.c
5953 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5955 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5956 send keepalive packets. The packet can be sent by clients,
5957 servers and routers.
5959 Added function silc_socket_set_heartbeat into the file
5960 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5961 If not set, the heartbeat is not performed. The actual
5962 heartbeat is implemented in the low level socket connection
5963 library. However, application is responsible of actually
5966 Added silc_server_send_heartbeat to send the actual heartbeat
5967 packet into silcd/packet_send.[ch]. Server now performs
5968 keepalive with all connections.
5970 * Added silc_task_get_first function into lib/silcutil/silctask.c
5971 to return the timeout task with shortest timeout. There was a bug
5972 in task unregistration that caused problems. TODO has been
5973 updated to include that task system must be rewritten.
5975 * The client library will now resolve the client information when
5976 receiving JOIN notify from server for client that we know but
5977 have incomplete information.
5979 * Rewrote parts of silc_server_remove_from_channels and
5980 silc_server_remove_from_one_channel as they did not remove the
5981 channel in some circumstances even though they should've.
5983 * Encryption problem encountered in server:
5985 The LEAVE command used to send the Channel Key packet to the
5986 router immediately after generating it. However, the code
5987 had earlier sent Remove Channel user packet but not immediately,
5988 ie. it was put to queue. The order of packets in the router
5989 was that Channel Key packet was first and Remove Channel User
5990 packet was second, even though they were encrypted in the
5991 reverse order. For this reason, MAC check failed. Now, this
5992 is fixed by not sending the Channel Key packet immediately but
5993 putting it to queue. However, this is more fundamental problem:
5994 packets that are in queue should actually not be encrypted
5995 because packets that are sent immediately gets encrypted
5996 actually with wrong IV (and thus MAC check fails). So, packets
5997 that are in queue should be encrypted when they are sent to
5998 the wire and not when they put to the queue.
6000 However, the problem is that the current system has not been
6001 designed to work that way. Instead, the packet is encrypted
6002 as soon as possible and left to the queue. The queue is then
6003 just purged into wire. There won't be any fixes for this
6004 any time soon. So, the current semantic for packet sending
6007 o If you send packet to remote host and do not force the send
6008 (the packet will be in queue) then all subsequent packets to the
6009 same remote host must also be put to the queue. Only after the
6010 queue has been purged is it safe again to force the packet
6013 o If you send all packets immediately then it safe to send
6014 any of subsequent packets through the queue, however, after
6015 the first packet is put to queue then any subsequent packets
6016 must also be put to the queue.
6018 Follow these rules and everything works fine.
6020 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Added new function silc_server_remove_clients_by_server to
6023 remove all client entries from ID list when the server connection
6024 is lost. In this case it is also important to invalidate all
6025 client entires as they hold the invalid server entry. This
6026 fixes fatal bug when server has lost connection and will reconnect
6029 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6031 * Made some sanity checks to silc_server_daemonise like to check
6032 whether the requested user and group actually exists.
6034 * Added sanity check to SKE's silc_ske_responder_finish to check
6035 that the public and private key actually is valid.
6037 * Invalidate the client's nickname when receiving Replace ID
6038 packet and the Client ID is being replaced. This means that the
6039 server will query the nickname if someone needs it (client)
6042 * Sort the ID Cache in client library when the ID Cache data
6043 has changed (needs sorting).
6045 * Do not allow for SILC client to create several connections to
6046 several servers. The client does not support windows right now
6047 and generating multiple connections causes weird behaviour.
6049 Irssi-silc client does support windows and can handle several
6050 connections without problems, see: www.irssi.org and SILC plugin.
6052 * Fixed some places where client was added to the IDList. The
6053 rule of thumb is following (in order to get everything right):
6054 If the client is directly connected local client then the
6055 `connection' argument must be set and `router' argument must be
6056 NULL to silc_idlist_add_client function. If the client is not
6057 directly connected client then the `router' argument must
6058 bet set and the `connection' argument must be NULL to the
6059 silc_idlist_add_client function.
6061 * The funtion silc_server_packet_send_local_channel actually did
6062 not check whether the client was locally connected or not. It
6063 does that now. Fixed a bug related to LEAVE command.
6065 * Fixed Remove Channel User payload parsing bug in server's
6066 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6068 * The server's silc_server_save_channel_key now checks also the
6069 global ID list for the channel as it might not be in the local
6070 list. Fixed a bug related to LEAVE command.
6072 * Is this the end of the [<unknown>] buglet that has been lurking
6073 around for a long time? A little for loop fix in server's
6074 silc_server_command_whois_parse that is used by both IDENTIFY
6075 and WHOIS command. At least, this was a clear bug and a cause
6076 of one type of [<unknown>] buglet.
6078 * WHOIS and IDENTIFY commands call the function
6079 silc_server_command_[whois/identify]_check function even if
6080 we are not router server.
6082 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6084 * Added --with-gmp configuration option. If set the GMP
6085 is always compiled in the SILC source tree. If not set then
6086 it is checked whether the system has the GMP3 installed. If
6087 it has then the GMP won't be compiled (the system's headers
6088 and library is used), if it doesn't have it then the GMP is
6089 compiled in the SILC source tree.
6091 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * Changed RSA private exponent generation to what PKCS #1
6094 suggests. We try to find the smallest possible d by doing
6095 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6096 not security fix but optimization.
6098 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6100 * Added new config entry [Identity] to fork the server and run
6101 it as specific user and group. A patch from Bostik.
6103 * Imported Dotconf configuration library into lib/dotconf.
6104 This will be used to create the SILC configuration files later.
6105 It will appear in the distsribution after this commit.
6107 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6109 * A big code auditing weekend happening. Auditing code for
6110 obvious mistakes, bugs and errors. Also, removing any code
6113 Removed files for being obsolete:
6115 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6116 inline in the file lib/silcutil/silcbuffer.h)
6118 o lib/silcutil/silcbufutil.c (the header has inline versions)
6120 Changed code to fix possible error conditions:
6122 o The buffer formatting routines now check that the destination
6123 buffer really has enough space to add the data. This applies for
6124 both buffer formatting and unformatting
6125 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6126 unformatting was changed to accomodate following rules:
6127 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6128 sent to the function while XXX_*STRING will not allocate or copy
6129 the data into the buffer. Instead it sets the pointer from the
6130 buffer into the pointer sent as argument (XXX_*STRING used to
6131 require that the pointer must be allocated already). This change
6132 makes this whole thing a bit more consistent and more optimized
6133 (note that the data returned in the unformatting with XXX_*STRING
6134 must not be freed now). The routines return now -1 on error.
6136 o Tried to find all code that use buffer_format and buffer_unformat
6137 and added return value checking to prevent formatting and
6138 especially unformatting errors and possible subsequent fatal
6141 o Changed ske->x and ske->KEY to mallocated pointers in
6142 lib/silcske/silcske.h. Fixed possible data and memory leak.
6144 o Added return value checking to all *_parse* functions. Fixed
6145 many memory leaks as well.
6147 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6148 so that buffer overflows would not happen. All code now also
6149 checks the return value as it can fail.
6151 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Added reconnection support to server if the normal server looses
6154 its connection to the router (for example if router is rebooted).
6155 The server performs normal reconnection strategy implemented
6156 to the server. Affected file silcd/server.c.
6158 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6160 * Added new packet type SILC_PACKET_SET_MODE that is used to
6161 distribute the information about changed modes (for clients,
6162 channels and clients channel modes) to all routers in the
6163 network. Updated the protocol specification accordingly.
6165 Added functions into silcd/packet_send.c and
6166 silcd/packet_receive.c: silc_server_send_set_mode,
6167 silc_server_set_mode.
6169 Added new files silcmode.[ch] into lib/silccore that implements
6170 the encoding and decoding of Set Mode Payload. Added new type
6171 SilcSetModePayload. Moved the definitions of different modes
6172 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6174 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6176 * Oops, a little mistake in server's connection authentication
6177 protocol. The protocol is not ended with FAILURE but with
6178 SUCCESS if the authentication is Ok. :) Affected file is
6181 * Implemented NICK_CHANGE notify handling in server in the file
6182 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6183 the local clients on the channel. After the changing nickname
6184 in router environment snhould work and the [<unknown>] nickname
6185 should appear no more.
6187 The silc_server_replace_id function that receives the Replace ID
6188 payload now sends the NICK_CHANGE notify type also in the file
6189 silcd/packet_receive.c
6191 * Changed WHOIS and IDENTIFY command to support the maximum amount
6192 of arguments defined in protocol specs (3328 arguments). This
6193 fixed a bug that caused problems when there were more than three
6196 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6198 * Added extra parameter, command identifier, to the
6199 silc_client_send_command so that explicit command identifier
6202 Changed that ID list routines uses specific command identifier
6203 when sending WHOIS/IDENTIFY requests to the server so that they
6204 can be identified when the reply comes back.
6206 Affected files lib/silcclient/command.[ch],
6207 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6209 * Added `sender' argument to silc_server_packet_send_to_channel
6210 to indicaet the sender who originally sent the packet to us
6211 that we are now re-sending. Ignored if NULL. Affected file
6212 silcd/packet_send.[ch].
6214 * Added some server statistics support in silcd/server_internal.h
6215 SilcServerStatistics structure and around the server code. Also
6216 send some nice statistics information when client is connecting
6219 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Fixed channel ID decoding in server's JOIN command reply in
6222 silcd/command_reply.c
6224 * Fixed braodcasting of replace ID payload to not to send it if
6225 we are standalone server in silcd/packet_receive.c.
6227 * Fixed all channel message sending routines to not to send
6228 packets to clients that has router set, since they are routed
6229 separately in the same function earlier. Affects file
6230 silcd/packet_send.c and all channel packet sending functions.
6232 * In USERS reply, res_argv[i] are not allocated, the table
6233 is allocated. Thus changed that free the table, not its
6236 * In server's whois_check and identify_check if the client is
6237 locally connected do not send any WHOIS commands - they are not
6240 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6242 * Fixed some minor bugs in client when sending WHOIS command. The
6243 arguments was in wrong order.
6245 * Removed statis function add_to_channel from server in
6246 silcd/command.c that was previously used with the joining but
6249 * Tested USERS command in router environment successfully with two
6250 routers, two servers and two clients.
6252 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6254 * Reorganized the USERS command and command reply in client library
6255 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6256 When the command is given by user we register a pending command
6257 callback that will reprocess the command after the reply has been
6258 received from the server. When reprocessing the packet we then
6259 display the information. Thus, the USERS information is displayed
6260 now in the command callback instead of in the command reply
6261 callback. The processing of the command is same as previously
6262 when server has sent the command reply in the JOINing process.
6264 * Added to USERS command in silcd/command_reply.c to join the client,
6265 we didn't use to know about, to the channel after we've created
6266 a client entry for it. Also, for clienet we did know already still
6267 check whether it is on the channel or not and add it if not.
6269 * Removed silc_server_command_join_notify as the function and its
6272 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Changed the client's pending command handling to the same as the
6275 server's pending command handling. It is also now possible to
6276 execute command reply functions from other command reply
6277 function as the function callbacks for commands and command
6278 replies are one and same. The pending commands are not static
6279 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6280 in client connection context. Thus, pending commands are server
6281 connection specific as it is convenient.
6283 Changed the function silc_client_command_pending and
6284 silc_client_command_pending_del and added new function
6285 silc_client_command_pending_check. Removed the
6286 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6289 * Added cmd_ident, current command identifier, to the client
6290 connection context in lib/silcclient/client.h to keep track on
6291 command identifiers used in command sending. Client's command reply
6292 function handling now supports the mandatory command identifiers.
6294 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6295 funtions in client to fully support pending command callbacks.
6297 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6298 as one of the arguments to the application in the command reply
6301 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6302 before first releasing SILC but came back. Now it is removed again
6303 and should come back nomore. The FORWARDED flag was used only
6304 by the JOINing procedure by forwarding the command packet to router.
6305 Now, the JOINing procedure has been changed to more generic (due
6306 to various router environment issues) and FORWARDED is not needed
6307 anymore for anything. The protocol specification is yet to be
6310 Now, removed silc_server_packet_forward from server and the flag
6311 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6313 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6315 * Renamed NAMES command to USERS command. The NAMES was named that
6316 due to historical reasons. Now it is renamed. Also, rewrote
6317 parts of the USERS command. The nickname list is not sent anymore
6318 by the server. Only Client ID and mode lists are sent in the USERS
6319 command. Changed this also to the protocol specification.
6321 The client now resolves the names and stuff after it receives
6322 the USERS list from the server when joining to the channel.
6324 * WHOIS and IDENTIFY commands has been changed to support multiple
6325 Client ID's per command. One can now search for multiple users
6326 in the network by sending only one WHOIS or IDENTIFY command.
6327 Changed the code and the protocol specifications.
6329 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6330 uses silc_server_command_whois_parse to parse the request. */
6332 * If normal server, do not parse the WHOIS and IDENTIFY requests
6333 before sending it to the router. Saves some time.
6335 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Fixed JOIN command on client library. Wrong number of arguments
6338 used to crash the client.
6340 * Added silc_server_channel_has_global function to check whether
6341 channel has global users or not.
6343 * Added silc_server_channel_has_local function to check whether channel
6344 has locally connected clients on the channel.
6346 * The silc_server_remove_from_one_channel now checks whether the
6347 channel has global users or not after given client was removed from
6348 the channel. It also checks whether the channel has local clients
6349 on the channel anymore. If it does not have then the channel entry
6350 is removed as it is not needed anymore.
6352 * The silc_server_notify now checks on JOIN notify whether the joining
6353 client is one of locally connected or global. If it is global then
6354 the channel has now global users on the channel and that is marked
6355 to the channel entry. Also, it now saves the global client to
6356 global list who is joining and JOINs it to the channel. This is
6357 for normal server, that is.
6359 Changed silc_server_send_notify_on_channel,
6360 silc_server_packet_relay_to_channel and
6361 silc_server_packet_send_to_channel check if we are normal server
6362 and client has router set (ie. global client) do not send the
6363 message to that client, as it is already routed to our router.
6365 * Implemented LEAVE notify type handling in silc_server_notify
6368 * Tested LEAVE command in router environment successfully. Tested
6369 with two routers, two servers and two clients.
6373 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6375 * Implemented SIGNOFF notify type handling in silc_server_notify
6378 * silc_server_remove_id now removes the client entry from all channels
6379 it has joined and thusly sends SIGNOFF notify type.
6381 * Rewrote the NAMES list generation in server by removing two excess
6382 loops. The lists are created now inside one loop.
6384 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6386 * silc_server_remove_channel_user checks now also global list
6387 for channel and client.
6389 * silc_server_new_channel_user checks now both local and global
6390 list for channel and client. Fixed a bug in client id decoding.
6391 Used to decode wrong buffer.
6393 * silc_server_channel_message checks now both local and global
6394 list for channel entry.
6396 * Tested channel joining (hence JOIN) in router environment
6397 successfully. Tested with two routers, two servers and two
6400 * Tested channel message sending in router environment successfully.
6402 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * Added silc_server_save_channel_key into server.[ch] to save the
6405 received channel key in Channel Key payload processing. It is
6406 also used in JOIN command reply handling.
6408 Equivalent function silc_client_save_channel_key added into
6409 client.[ch] into client library.
6411 * Changed JOIN command reply to send information whether the channel
6412 was created or not (is existing already) and the channel key
6413 payload. Changed protocol specs accordingly.
6415 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6416 the request was sent by ID and not by nickname. Crashed on
6419 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6421 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6422 now correctly save the received data.
6424 * silc_server_free_sock_user_data now notifies routers in the
6425 network about entities leaving the network.
6427 At the same time implemented functions silc_server_remove_id
6428 and silc_server_send_remove_id to receive and send REMOVE_ID
6429 packets. The packet is used to notify routers in the network
6430 about leaving entities. The ID removed will become invalid in
6433 * Added function silc_idlist_del_server into server. Removes and
6434 free's server entry from ID list.
6436 * silc_server_private_message function now checks, if we are router,
6437 that the destination ID really is valid ID, naturally.
6439 * In router when NEW_ID packet is received (for new client) the
6440 hash of the Client ID is saved in the ID Cache but the
6441 client->nickname is set to NULL, instead of putting the hash
6444 IDENTIFY command now also checks that client->nickname must be
6445 valid. If it is not if will request the data from the server who
6446 owns the client. Added new function
6447 silc_server_command_identify_check.
6449 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6450 to set the command to already allocated Command Payload.
6452 * Tested private message sending in router environment with two
6453 routers, two servers and two clients. Fixed minor bugs and now
6456 * Fixed segfault from client's NAMES command. Used to crash if
6459 * Forwarded packets must not be routed even if it is not destined
6460 to the receiver. Changed server code comply with this.
6462 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Added `require_reverse_mapping' boolean value to ServerParams
6465 structure. If TRUE (not default) the server will require that
6466 the connecting host has fully qualified domain name.
6468 If the reverse mapping is not required and hostname could not be
6469 found the IP address is used as hostname.
6471 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6473 * Implemented version string checking to both client and server.
6474 The check is incomplete currently due to the abnormal version
6475 strings used in development version of SILC.
6477 * Changed all command functions in server to use the new
6480 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6482 * Changed char *data to unsigned char *data in ID Cache system to
6483 support binary data as ID Cache data. Changed code to support
6484 binary data in lib/silccore/idcache.c.
6486 * Renamed silc_server_packet_relay_command_reply to
6487 silc_server_command_reply as it is normal packet receiving
6488 function. Rewrote the function to accept command replys for
6489 servers and not only for clients.
6491 * Mark remote router always as registered server if we are connecting
6492 to it. Otherwise, commands sent by the router to us are ignored.
6494 * All ID List find routines now returns the ID Cache Entry pointer
6495 as well if requested.
6497 * WHOIS command works now in router environment, tested with two
6498 routers, two servers and two clients.
6500 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6501 in router environment (as it is almost equivalent to WHOIS) but
6502 hasn't been tested thoroughly. Added new functions:
6504 silc_server_command_identify_parse
6505 silc_server_command_identify_send_reply
6506 silc_server_command_identify_from_client
6507 silc_server_command_identify_from_server
6509 * Disabled route cache adding because adding two different ID's with
6510 same IP replaces the old cache entry thus giving wrong route.
6511 The entry->router->connection is always the fastest route anyway
6512 so route cache may not be needed. Of course, new routes maybe
6513 established after receiving the ID when the entry->router->connection
6514 might not be anymore the most optimal.
6516 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6518 * Add route cache for received ID for fast routing.
6520 * Added silc_server_packet_route to route received packet on router
6521 that is not destined to us.
6523 * Renamed silc_server_get_route to silc_server_route_get.
6525 * Added id_string and id_string_len fields into SilcServer to
6526 include encoded ServerID for fast comparing without excess
6527 encoding of the ID's.
6529 * Cleaned up WHOIS command on server side. Added following static
6532 silc_server_command_whois_parse
6533 silc_server_command_whois_check
6534 silc_server_command_whois_send_reply
6535 silc_server_command_whois_from_client
6536 silc_server_command_whois_from_server
6538 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6539 arguments in command replies. All command functions should be
6540 updated to use this macro.
6542 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6544 * Minor typo fixes on command reply handling on server.
6546 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6548 * Added silc_server_command_add_to_channel internal routine to add
6549 the client to the channel after router has created the channel and
6550 sent command reply to the server.
6552 * Added generic silc_server_send_command to send any command from
6555 * Use static buffer with ID rendering instead of duplicating data.
6557 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6559 * Fixed a channel user mode bug when joining to a channel server gave
6560 everybody channel founder rights, oops.
6562 * We mark ourselves as the router of the incoming server connection
6563 if we are router ourselves. This way we can check in some packet
6564 sending functions whether it is locally connected server. For
6565 incoming router connections we put NULL.
6567 * For router sending packets locally means now always sending the
6568 packet cell wide; to local clients and local servers. For normal
6569 server sending packet locally means sending it to only local
6572 * Fixed the JOIN command to really work in router environment. If the
6573 channel is created it is always created by the router. Router is
6574 also responsible of making the initial joining to the channel,
6575 sending JOIN notify to the sending server and distributing
6576 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6577 does not exist server doesn't do anything else but forward the
6578 command to the router which performs everything.
6580 * Added silc_server_send_channel_key function to send the Channel Key
6583 * Added silc_server_create_channel_key to create new channel key. The
6584 channel key is now re-generated everytime someone joins or leaves
6585 a channel, as protocol dictates. Note: channel->key_len is the
6588 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6591 packet_receive.[ch] to separate packet sending and receiving
6592 routines. The server.[ch] now includes everything else including
6593 actual packet processing (writing and reading data) and other
6596 Renamed silc_server_private_message_send_internal to
6597 silc_server_send_private_message. The routine is still though
6598 used only to relay private messages as server does not send
6599 private messages itself.
6601 Renamed silc_server_new_channel to silc_server_create_new_channel
6602 and added new function sicl_server_new_channel that handles the
6603 incoming New Channel packet. Added also new sending function
6604 silc_server_send_new_channel to send New Channel Payload.
6606 * Added new function silc_server_notify to process incoming notify
6607 packet to the server/router. Server may then relay the notify
6608 to clients if needed.
6610 * Added new function silc_server_new_channel_user to process incoming
6611 New Channel User packet. Router will redistribute the packet and
6612 send JOIN notify to its local clients and locally connected servers
6613 if needed. Normal server will send JOIN notify to its local client
6614 on same channel when received this packet. Added also corresponding
6615 sending function silc_server_send_new_channel_user to sent the
6618 * Added boolean route argument to send_notif_to_channel and
6619 packet_send_to_channel functions to attempt to route the packet
6620 if it is TRUE and send only locally if it is FALSE.
6622 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * silc_server_replace_id now broadcasts the received replace ID
6625 packet if it is not broadcast packet already. The router must
6626 broadcast to inform other routers about changed ID.
6628 * Added backpointer to server's router into SilcServer context in
6629 silcd/server_internal.h.
6631 * Fixed silc_server_packet_broadcast to send correct broadcast
6634 * The channel key is now distributed to the local client as soon
6635 as it is received from the router (in router environment) so that
6636 no other packet may be sent for the channel until client has
6639 * silc_server_remove_channel_user now broadcasts the received
6640 Remove Channel User packet if it is not broadcast packet already.
6641 The router must broadcast to inform other routers about removed
6644 * Added users field into SilcPacketContext that is a reference count
6645 of the context. One can increase the reference count by calling
6646 silc_packet_context_dup which is now changed to just increase the
6647 reference count instead of duplicating the data. The reference
6648 count is decresed by calling silc_packet_context_free that will
6649 free the data after the reference count hits zero.
6651 For now on the packet context and everything allocated into it
6652 (including the raw packet from network) must be freed by calling
6653 the new silc_packet_context_free function. Added also new function
6654 silc_packet_context_alloc that must be used now to allocate the
6655 context. This also means that if a routine is asynchronous from
6656 silc_[client/server]_packet_parse_type the packet context must
6657 be duplicated by calling silc_packet_context_dup. Otherwise it
6658 gets free'd after silc_[client/server]_packet_parse_type returns.
6659 Also, one must remember that if packet is duplicated then its
6660 reference count must be decresed by calling the free function as
6661 many times as it was duplicated.
6663 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6664 from both client and server.
6666 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Made joining to a channel working in router environment.
6670 * Cleaned up JOIN command on server side and create function
6671 silc_server_command_join_channel internal routine to make the
6674 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Changed silc_command_pending list to SilcDList. Also, added
6677 `ident' field to SilcServerCommandPending structure to identify
6678 the reply and to call correct callback.
6680 Added silc_server_command_pending_check function to replace the
6681 corresnponding macro. The silc_command_pending list is not
6684 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6685 to set identifier to previously allocated Command Payload. It
6686 is used to set identifier for command when resending Command
6689 * Added silc_command_payload_encode_payload to encode Command
6690 Payload buffer from SilcCommandPayload structure.
6692 * Added silc_argument_payload_encode_payload to encode Argument
6693 payload buffer from SilcArgumentPayload structure.
6695 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Changed WHOIS command to support router connection on server side.
6698 The whois request is always sent to router unless the server is
6699 standalone server. After server has received the reply from the
6700 router will it send the reply to the client.
6702 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6703 broadcast received broadcast packet. The function is used only
6704 by router. The broadcast packet is always sent to the router's
6707 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6708 render given ID to printable string, for log files for example.
6710 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6712 * Made basic router to router connections working. At least they
6713 can now connect to each other but nothing really works the way
6714 they are supposed - yet.
6716 * Added new initiator token to RouterConnection configuration
6717 file in silcd/serverconfig.[ch]. It is used to tell whether we
6718 are the initiator to the remote router or whether we'll expect
6719 the other end to connect.
6721 * Moved registering of listener task to silc_server_init, hence
6722 the server starts listenning as soon as it is run, even if it
6723 does not have connections to other routers. Let's see how well
6726 * Changed default connection retry timeouts for more suitable in
6729 * Removed cipher and such arguments from silc_idlist_add_client
6730 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6731 Added new function silc_idlist_add_data to add the keys and stuff
6734 * Added SilcIDListData structure and added it to SilcClientEntry
6735 and SilcServerEntry as their first field in the structure. This
6736 way we can explicitly cast the ID entries to the SilcIDListData
6737 structure and get common data for the entries. In past, we had
6738 to first check what type of connection it is and then cast it to
6739 correct ID entry type. Now, we can directly cast the opaque
6740 pointer to the SilcIDListData (no matter what ID entry it actually
6741 is) and get the data needed.
6743 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6745 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6746 in some circumstances even if threre were timeout tasks, though not
6747 IO tasks, but tasks anyway. Now fixed.
6749 * Defined SilcServerConnection structure to hold connection specific
6750 stuff about directly connected servers and routers. The definition
6751 is currently in silcd/server_internal.h. I thought about having
6752 a bit more important role fro this struct but for now it is used
6753 only when connecting to other server (or router actually).
6755 * Added connecting retry support in server when connecting to
6756 router(s). The retry feature implement exponential backoff
6757 algorithm. Also, added SilcServerParams structure to hold default
6758 parameters for server. For now, it include these retry settings
6759 and are hard coded. After server is moded to be as Silc Server
6760 Library this structure will be more important.
6762 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6764 * Changed client librarys channel->clients table to SilcList and
6765 changed code accordingly.
6767 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * Changed client's channel table to SilcList and changed code
6770 accordingly. Also changed SilcChannelClientEntry to include back-
6771 pointer to the channel so that client entry can use that structure
6772 as list as well and we have fast cross-reference to the channel.
6773 This change dramatically decreased the complexity of channel
6774 handling with client entry and vice versa (removed one extra
6775 loop when searching for channel entry from many functions).
6777 * Changed server->sim from table to SilcDList and changed code
6780 * NAMES command can now be used from user interface. It will show
6781 the user list on the channel, neatly.
6783 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6784 Code now saves realname of the user if it becomes available.
6786 * Renamed configure.in to configure.in.pre and made ./prepare
6787 script to automatically add correct version string to
6788 configure.in which it creates from configure.in.pre.
6790 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6792 * NAMES command reply now shows users mode with the nickname when
6795 * Moved silc_client_ch[u]mode[_char] functions from
6796 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6797 place sucks, they are utility functions and should be in some
6800 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6802 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6805 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6809 * Added TRQ (efficient deque and list library) into lib/trq. This is
6810 a very good list library that is currently used in the SILC. Defined
6811 SilcList API over the library because I didn't like the API very
6812 much. See lib/trq/silclist.h for the API and examples of how to
6813 use the API. Fixed various places in the code to use the new
6814 SilcList API. The SilcList is meant for lists that has a structure
6815 already defined as a list. It is not suitable to add just some
6816 context to the list (in TRQ, the context is the list actually).
6818 So, I defined SilcDList that can be used for the purpose where
6819 predefined list structure does not exit. This can be used as
6820 such list. Now some context just can be added to the SilcDList.
6821 Currently this list is not used in the SILC just yet, though there
6822 are a lot places where this can replace dynamically allocated
6823 tables and I will fix these places, later, to use SilcDList.
6824 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6825 and use TRQ internally).
6827 Also fixed some annoying warning messages that the original TRQ
6828 code generated. Also minor changes to TRQ's Makefile.in.
6830 * Added support for querying by Client ID to both WHOIS and
6831 IDENTIFY commands into server, as required by the protocol.
6833 * Removed method function pointers from SilcBuffer structure. They
6834 weren't used to anything and just increased the context size for
6835 no good reason. This change also made silc_buffer_alloc and
6836 silc_buffer_free functions inline functions.
6838 * Disabled command flooding detection support until it's fixed so
6839 that it accepts commands in but does not execute them more than once
6842 * Added silc_net_localhost(), to return local hostname, into
6843 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6844 that must be initialized before calling silc_client_init.
6846 * Added new function: silc_server_send_notify_on_channels to send
6847 notify messages to all channels client has joined. It is assured
6848 that the message is sent only once per client.
6850 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6851 lib/silcutil/silcutil.[ch] as silc_format function. The new
6852 function is generic and is used by server as well, not only by
6853 the logging routines.
6855 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6856 the provided version string was not acceptable. Added new function:
6857 silc_ske_check_version into lib/silcske/silcske.h. The function
6858 must be implemented by the application (client or server) and it
6859 does not reside in the SKE library. The function checks the version
6860 string remote end sent.
6862 * Added back pointers (to opaque context and to SilcSocketConnection)
6863 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6865 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6866 duplicate packet context structure.
6868 * Changed `notify' client operation to send same arguments as client
6869 receives from server except for ID's. ID's are mapped to correct
6870 ID entry and that is returned. Also, if channel entry is not sent
6871 by server but the notify is for channel the channel entry is sent
6872 to application (otherwise application doesn't know that it is for
6873 channel (library gets it from packet's Destination ID)).
6875 * Added silc_client_remove_from_channels into client library to
6876 remove a client from all channels it has joined to. Used when
6877 received SIGNOFF notify from server. Added also new function
6878 silc_client_replace_from_channels to replace old ID entry with
6879 new ID entry on all channels. Used when received NICK_CHANGE
6882 * Fixed ID Cache list handling in silc_idlist_get_client in
6883 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6884 to get (or query) client by ID.
6886 * Updated TODO list.
6888 * Added connection authentication status message defined by the
6889 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6890 support for these into the code in client and server side.
6892 * Added generic function silc_client_send_command to send any command
6893 with variable argument list. Application should use this function
6894 to send commands if the command functions provided by the library
6895 does not suite for the application's user interface needs.
6897 * Added new `failure' client operation. Application is notified about
6898 received failure packet if client is executing a protocol. In this
6899 case the protocol's execution has failed.
6901 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6902 is required by the protocol.
6904 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6905 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6908 * Added status flag to SilcSKE object to indicate realtime status
6909 of the SKE protocol.
6911 * Application receives now exactly same command reply arguments as
6912 the library receives from server. However, if ID is received the
6913 corresponding ID entry is returned to the application (eg. Client
6914 ID is mapped to correct SilcClientEntry entry and that is returned).
6915 Changed command_reply client operation due to this change.
6917 * Changed all ID's in commands and in command replys as ID Payloads.
6918 Change affected both client and server side codes.
6920 All ID's sent in SILC network (with execption of ID's in SILC
6921 Packet header) are sent in ID Payload to support variable length
6924 * Server now notifies nick changes and notifies all clients on
6925 the channels about the new nickname (about the new Client ID,
6928 * Implemented CMODE command to change channel modes. Supports all
6929 channel modes defined by the protocol specs except ban and invite
6930 lists. (Also, private channel key mode is supported but support for
6931 setting private channel key in client is missing, thus, this mode
6932 has no effect on client side (except that server requires that the
6933 client uses private channel key and normal channel traffic does not
6936 Also, invite mode works per se, but INVITE command does not work
6937 yet correctly, so you can set channel as invite only channel but
6938 inviting clients to the channel does not work (it is yet to be
6939 thought what's the best way to do it).
6941 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6942 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6943 Implemented CUMODE command to change user's mode on the channel.
6944 Supports all modes defined by the protocol specs.
6946 * Added NAMES command reply to return users modes on the channel.
6948 * Removed unnecessary and slow ciphers from lib/silccrypt.
6950 * Set SO_KEEPALIVE option to connection sockets by default.
6952 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6954 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6955 redefined the Notify Payload into protocol specs.
6957 * Added silc_id_payload_parse_id to get ID directly from raw
6960 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6963 accept searching by Client ID as well.
6965 * Added support for LEAVE and SIGNOFF notify types in client library.
6967 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6968 to parse ID Payload from raw data.
6970 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6972 * Added flags parameter into silc_ske_assemble_security_properties
6973 function in lib/silcske/silcske.[ch].
6975 * Changed notify client operation to fit better for notify messages
6976 sent by server. The notify payload received from server is now
6977 passed to the application (after parsing it to SilcNotifyPayload).
6978 It is application's responsibility to retrieve the arguments
6979 from the payload and show the message the way it wants. The message
6980 sent by server is implementation specific.
6982 * Changed public keys to comply with the protocol specification.
6983 Old public keys are not supported anymore and are not compatible.
6985 * Removed nickname from Channel Payload as the latest draft removed
6986 it. The client must resolve the nickname from the NAMES command
6987 reply received when it joined the channel.
6989 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6991 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6993 * Fixed some errors in protocol specification drafts.
6995 * Created lib/silccore/silcnotify.c to implement Notify Payload
6996 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6997 generic payloads described by protocol specifications. The file
6998 includes implementations for ID Payload and Argument Payload.
7000 * Changed Command Payload implementation to use the new Argument
7001 Payload. Changed command_xxxx_payload to command_payload_xxxx
7002 to comply with SILC coding conventions.
7004 * Added suppport for Argument Payload handling in Notify Payload
7005 implementation as protocol requires it. Added the new support
7006 into server and client lib as well.
7008 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7010 * Added support for multiple nicknames on same channel. [n] is
7011 added locally to the nickname if there are more than one same
7012 nicknames on the channel.
7014 * Server now sends all nicknames that matched WHOIS request.
7015 Client also shows the list received from server.
7017 * Added TOPIC command to client side. User can now set and show
7018 current topic on channel.
7020 * Added MOTD command to client and server. Also, server sends the
7021 motd when client connects to the server.
7023 * Changed version strings to comply ISO 8601.
7025 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7027 * Fixed protocol error handling in client library. It should now
7028 cope even if the SKE fails for some reason.
7030 * Made new protocol specification drafts for submitting to IETF.
7032 * Implemented TOPIC command to server in silcd/command.c.
7034 * Added two new notify types into lib/silccore/silcnotify.h:
7035 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7036 notify nickname change and topic setting/change on a channel.
7038 * API change of command_reply operation in client library. The
7039 application gets now the status type received from server as well.
7041 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7043 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7045 * Cras fixed and optimized the packet handling even further and
7046 it should work now. Minor change to the prototype of function
7047 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7049 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7051 * Added new function into lib/silcutil/silcschedule.[ch]:
7052 silc_schedule_with_fd to select() a specified fd. The function
7053 returns after timeout expires or data arrives or goes. The
7054 function is used by packet routines to wait that all data is
7055 received from network.
7057 * Fixed data reading from network in lib/silccore/silcpacket.c.
7058 The code now assures that all data is read from the fd and then
7059 continues packet processing. This was a bug fix since the code
7060 used to drop some data in some circumstances.
7062 * Added new function into lib/silcclient/client.[ch]:
7063 silc_client_start_key_exchange to start key exchange after
7064 connection has been established to server. The code internally
7065 now uses this funtion but its main purpose was to provide it
7066 for applications that perform their own connecting. After
7067 application has created a connection it merely calls this
7068 function to start the key exchange between client and server.
7069 The library takes care of everything else after that.
7071 Updated also lib/silcclient/README to explain the usage of
7074 * Do not send to application information that connection has
7075 been established. Application gets notified it by connect
7078 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7080 * Applied cras's patch to add silc_schedule_one function. The
7081 function runs scheduler once and returns.
7083 * Fixed the scheduler after cras messed it up. The timeout
7084 handling works now as it's supposed to work.
7086 * Added into lib/silccore/ silcnotify.h to include notify
7087 message types support. Changed silc_server_send_notify*
7088 functions, in server.[ch], to support those new notify types.
7089 Added the support for the notify types into client library,
7090 as well. Added new notify client operation into ops.h in
7093 * Changed silc_server_packet_send_to_channel to send normal
7094 packets instead of just channel message packets. The function
7095 is now used to send the notify packets to channels. It is not
7096 used to send channel message packets anymore, as server never
7099 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7100 va_arg()s as it seems to require it nowadays. I guess, if SILC
7101 is compiled with older va_arg() the new code should work anyway.
7103 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7105 * Splitted core library. Core library (lib/silccore) includes
7106 now only SILC protocol specific core (and common) components.
7107 Created new utility library (lib/silcutil) that includes more
7108 generic purpose stuff. The stuff for util library was taken
7109 from the old core library. This was minor and easy split.
7111 * Created SILC Client Library (lib/silcclient) that includes
7112 implementation of the SILC client without user interface. This
7113 was major move from silc/ directory. The code has been changed
7114 so that it is transparent towards the user interface. The
7115 silc/ directory includes now the same user interface as before
7116 and it uses the new client library. Read lib/silcclient/README.
7117 Basicly, the client library performs everything else related
7118 to SILC except user interface handling. Also, configuration
7119 files are considered to be part of user interface and library
7120 does not handle them.
7122 This change also changed a lot of structures, function naming etc.
7123 Most important change was that SilcClientWindow object was
7124 renamed to SilcClientConnection in the client library. Created
7125 also new file lib/silcclient/ops.h. Also added new files
7126 silc/local_command.[ch] and silc/client_ops.[ch].
7128 All these changes were made to make it easier for user interface
7129 designers to create what ever user interface for the SILC client
7132 It is also expected that the server will be moved to lib
7133 directory as well and SILC Server Library will be created;
7134 sometimes in the future.
7136 * Removed Local commands from lib/silccore/silccommand.h as
7137 they are application specific and new client library does not
7138 handle any of those anymore.
7140 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7141 old client implementation in silc/.
7143 * Added support for callback functions in SILC_LOG_* macros.
7144 Application can now set its own callbacks that will be called
7145 instead of using the default functions that will always print
7146 the debug messages to stderr (or stdout). Also, debugging can
7147 now be disabled by setting silc_debug to FALSE and re-enabled by
7148 setting it to TRUE. Note, that logging will still work even
7149 if debugging is disabled.
7151 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7152 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7153 silc_log_reset_debug_callbacks.
7155 * To enable debugging in silc client one must give now -d
7156 option on command line.
7158 * Changed silc_schedule_init to automatically allocate task queues
7159 if they are not allocated before calling it.
7161 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7163 * Added GMP 3.1 into math library.
7165 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7167 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7168 a channel in SILC network. The packet is used by servers and
7169 routers to notify other routers that user has left a channel.
7170 This little feature was missing until now. Added the feature
7171 to protocol specification as well.
7173 Added functions: silc_server_send_remove_channel_user and
7174 silc_server_remove_channel_user into server.[ch].
7176 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7177 lib/silccore/silcpacket.h. However, they are not implemented
7180 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7182 * Fixed joining to a channel and sending channel messages
7183 between server and router. The channel message sending should
7184 now work inside a cell.
7186 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7188 * Fixed the private message sending between server and router.
7189 The private message sending should now work inside a cell.
7191 * Added silc_server_replace_id into server.[ch] to replace
7192 existing ID in the SILC network.
7194 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7195 and silc_idlist_replace_server_id into idlist.[ch] in server.
7197 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Fixed the server to server connections. Server can again now
7200 connect to router. Router to router connections probably does
7203 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7205 * Added dynamic protocol registering support. Now protocols can
7206 registered and unregistered on the fly. Patch by cras.
7208 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7210 * Added lib/contrib directory to hold routines that some platforms
7211 don't have but are needed by SILC.
7213 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7214 into lin/contrib to provide getopt() and getopt_long() for
7215 those who don't have it.
7217 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7219 * Added AWAY command to client. When away message is set and
7220 client receives a private message packet the client automatically
7221 replies to the sender with the away message.
7223 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7224 bug seemed to be the cause of recent problems when compiling
7227 * Added version detection support to SKE protocol specification
7228 and added the new changes to the SKE implementation as well.
7229 There were other minor changes in the SKE protocol as well.
7231 Many changes in lib/silcske/silcske.[ch] and in
7232 lib/silcske/payload.[ch].
7234 * Added ^U functionality, clear input line. Patch from cras.
7236 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7238 * Mainly small bugfixes on core library. Fixed some debugging
7239 logging and buffer overflow in silclog.c.
7241 * Updated config.sub and config.guess on the distribution tree.
7243 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7245 * Added command lagging support in server. Client may execute
7246 commands now only once in two seconds.
7248 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7250 * Optimized packet reception. MAC computation and checking is now
7251 also more optimized. A lot previously duplicated code is now
7252 used as generic by both client and server.
7254 * Fixed key pair generation in clientutil.c
7256 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7258 * Added into lib/silccore/silcbufutil.[ch] new function;
7259 silc_buffer_realloc.
7261 * Moved generic packet sending/encryption functions to
7262 lib/silccore/silcpacket.[ch] from client and server. Some
7263 rewriting of the functions.
7265 * Moved all generic packet reception/decryption functions to
7266 lib/silccore/silcpacket.[ch] from client and server. The
7267 packet processing is now much cleaner in both client and server.
7268 These were major changes in both client and server.
7270 * Created many common functions in server to do packet sending.
7271 Previously code were duplicated a lot, this has been removed
7274 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7276 * Rewrote major parts of the ID cache system. Don't know
7277 whether it is better now or not but at least the API is more
7280 * Major rewrite on ID cache stuff on client because of the ID
7281 cache API changes. Added idlist.c to client.
7283 * Also major rewrite on ID cache stuff on server as well.
7284 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7285 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7286 in hand, instead they are all put into the ID cache system now.
7287 All server_idlist_* routines uses ID cache now instead of
7288 traversing its own lists (those lists does not exist anymore).
7289 SilcIDList though still exists. Also, SilcXXXEntry's are
7292 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7294 * Finally made the SKE implementation compliant to the protocol
7295 specification. All mp integers are now binary encoded as
7296 opposed being HEX encoded.
7298 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7301 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7302 functions: silc_[encode/decode]_pem. Also added function
7303 silc_encode_pem_file to PEM encode with newlines ('\n') for
7306 * SILC public keys are now encoded either PEM or binary. Same
7307 option is for private keys as well. By default private keys
7308 are binary encoded and public keys PEM encoded. Silly HEX
7309 encoding were removed.
7311 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7312 function to create fingerprints.
7314 * Fixed a bug in SHA1; does not change the original data anymore.
7316 * Partly implemented INFO command on client and server side.
7317 Fixed CLEAR command. Changes to SERVER command; show current
7318 server(s) when giving command without arguments. Added
7319 VERSION command to client.
7321 * Added check to server that unregistered connections cannot
7322 execute commands (unless it is specificly allowed).
7324 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Fixed screen refresh.
7328 * Fixed channel joining bug from client. On some circumstances
7329 client tried to join to a channel it had already joined.
7331 * Added public key verification process into client's protocol.c.
7332 The client now verifies the public key from user and saves
7333 it into ~./silc/serverkeys/ directory.
7335 Added into: clientutil.[ch]: silc_client_verify_server_key.
7337 * Changed SKE protocol's silc_ske_initiator_finish function
7338 to accept callback function that verifies the received public
7339 key. Removed old silc_ske_verify_public_key function.
7341 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7343 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7344 silc_pkcs_private_key[_data]_set.
7346 * Made the password and public authentication more cleaner in
7347 server's protocol.c.
7349 * Removed historic and obsolete protocol `channel_auth' from
7350 both client and server.
7352 * Removed wrong way of sending command status messages from
7353 server to client in server's command.c. The old way violated
7354 protocol specification.
7356 Changes to silccore/silccommand.[ch]: removed
7357 silc_command_encode_status_payload -> not needed anymore,
7358 changed silc_command_encode_payload_va to accept extra
7359 argument on variable argument list. The argument type must
7360 now be provided to the function. Also, added new function:
7361 silc_command_encode_reply_payload_va which is same as
7362 normal command_encode_payload_va except command status type
7363 is provided as extra argument.
7365 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7367 * Added ~./silc directory handling. The directory includes the
7368 public and private keys for the client.
7370 Added silc_client_check_silc_dir, silc_client_create_identifier
7371 and silc_client_load_keys.
7373 * Implemented SILC protocol compliant public key. Added public
7374 and private key saving to and loading from files.
7376 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7377 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7378 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7379 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7380 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7382 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7383 silc_pkcs_load_[public/private]_key.
7385 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7387 * Added silc_server_get_route (route.[ch]) to get connection
7388 data for the fastest route for given ID.
7390 * Implemented INVITE command on client and server. The command
7391 were re-defined in the SILC Protocol Specification and the
7392 implementation now complies with the specification.
7394 * Implemented PING command on client and server.
7396 * Implemented NAMES command on client and server. The server side
7397 supports currently only normal server not router server yet.
7398 Some changes to NAMES definition in SILC protocol specification.
7400 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7402 * Implemented LEAVE command on client and server.
7404 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7405 again. This change was made to the protocol as well. Server
7406 should not violate the protocol specification anymore.
7408 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7410 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7411 was tested. SOCKS4 was not but should work anyway.
