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],

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 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
35 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
36 client. Affected file irssi/src/silc/core/client_ops.c.

40 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
42 * Check for valid socket connection in client entries before
43 sending any messages. Fixes a crash, but doesn't fix some
44 other underlaying bug that is lurking there. Affected
45 file silcd/packet_send.c.
47 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
49 * $usermode, $cumode and $cumode_space expandos shouldn't do
50 anything with non-SILC server records. Affected file

53 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
55 * Fixed the silc_net_check_[host/local]_by_sock to support
56 IPv6 bound sockets as well. Now they can return IPv6 addresses
57 as well. Affected file lib/silcutil/silcnet.c.
59 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
60 Affected lib/silcutil/unix/silcunixnet.c.

63 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
65 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
67 * Added silc_hash_public_key and silc_hash_public_key_compare
68 functions to be used with SilcHashTable. They can be used to
69 hash public keys and compare public keys in hash table. Affected
70 file lib/silcutil/silcutil.[ch].
72 * Added support for specifying multiple public keys for Client
73 connection section in server configuration file. This makes it
74 possible to accept multiple public keys from same host, or to
75 make a section that accepts any incoming host, and have the
76 accepted public keys listed in the section.
78 Added functions silc_sever_[find/get]_public_key, added the
79 support for this actually to all connection sections but only
80 the Client section is currently allowed to specify multiple
83 Affected files are silcd/server.c, server_internal.h,
84 command.c, protocol.c, server_util.[ch], packet_receive.c.

90 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
92 * If silc_debug is TRUE, also output standard logging messages
93 to stderr with the debug output.
95 Made silc_log_reset_all() flushing all channels before returning.
96 Also fixed some documentation typos.
98 Affected files are lib/silcutil/silclog.[ch].
100 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

103 from single host, by checking also the type of the connection.
104 Fixed also the comparison of number of connections and number
105 of allowed connections. Affected files are silcd/server.c,
108 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
110 * Fixed the USERS command reply to save the user's mode on the
111 channel as well. Fixed JOIN command reply to check whether a
112 client is on channel already and not join it twice. Affected
113 file lib/silcclient/command_reply.c.
115 * Added new file silc-expandos.c into irssi/silc/core/ to return
116 various stuff for various signal for the statusbar etc. updating.
117 Now Irssi SILC client prints channel user modes etc. on the
120 * The user mode (like server/router operator changes) is now shown
121 on the Irssi SILC client's statusbar. The affected files are
122 irssi/src/silc/core/client_ops.c, silc-expandos.c.
124 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>

161 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
162 to avoid collisions with other libraries using same type names
165 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
167 * Added `prefer_ipv6' argument to the functions
168 silc_net_gethostbyname[_async]. If it is TRUE it will return
169 IPv6 address over IPv4. If FALSE IPv4 address is returned
170 even if IPv6 address was found. Affected files
171 lib/silcutil/silcnet.[ch].
173 * Added support silc_net_create_connection[_async] to fallback
174 to IPv4 address if IPv6 address could not be used (like if

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

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

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

280 Optimized the use of SKE Mutual flag usage. Use it only
281 if connection authentication protocol is not based in public
284 Renamed all SilcServerConfigSection* to SilcServerConfig*
285 to have a bit shorter names.
287 Affected files silcd/serverconfig.[ch], server.[ch], and

305 * Fixes to the silcd config template. Affected file is
306 doc/example_silcd.conf.in.
308 * Removed type casts from silc_calloc(), conforming to the
309 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
311 * Removed param_name member from client, server, and router
312 section structs, now identifying the param directly.
314 Added CONFIG_FREE_AUTH macro in config file parsing.
316 Affected files are silcd/serverconfig.[ch].
318 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
320 * Fixed command line parameter handling. All SILC initialization
321 is now done in silc_core_init() which also fixes autoconnecting
324 Affected files irssi/src/silc/core/silc-core.c,
325 irssi/src/fe-text/silc.c.
327 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
329 * Added new configuration options and blocks:
330 keepalive_secs, reconnect_count, reconnect_interval,
331 reconnect_interval_max, reconnect_keep_trying and
332 require_reverser_lookup. Added ConnectionParam block, and
333 implemented the connection parameters when connecting as
334 initiator and when accepting connections as responder.
336 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
337 whether given configuration value has been given already.
339 Affected files silcd/serverconfig.[c], server.[c].
341 * Splitted the doc/example_silcd.conf.in. Separated the crypto
342 algorithm parts and created new file silcalgs.conf, that
343 is now included from the example_silcd.conf.in.
345 * Optimized the silc_server_connect_to_router_second to take
346 the connection configuration object from the SilcServerConnection
347 object instead of finding it during the connecting phase.
348 Added the configuration object to SilcServerConnection struct.
349 Affected files silcd/server_internal.h, server.c.
351 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
353 * Add the client on channel after it was resolved at the
354 channel message receiving, and it was not already on the
355 channel. Affected file lib/silcclient/client_channel.c.
357 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
359 * Fixed the public key authentication to allocate always the

361 Affected file silcd/protocol.c.
363 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
365 * Unified the serverconfig.[ch]'s helper function interface.
366 Affected file silcd/serverconfig.[ch].
368 * Removed doc/example_silc.conf.in since it is redundant.
369 The make install will now install irssi/silc.conf file.
371 * Added new Passphrase and Publickey authentication methods to
372 config file, allowing both public key and passphrase based
373 authentication to be set at the same time.
375 Added `prefer_passphrase_auth' setting in config file which
376 can be used to set to prefer passwd auth if both passwd and
377 public key is set. If not set, public key is preferred.
378 This has effect only when being initiator (responder will try
381 Added support for authentication with passphrase and public key
382 at the same time. The passphrase is tried first always since
383 it is faster to check.
385 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
387 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
389 * Merged the new SILC Config library, with the server parsing

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

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

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

496 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
498 * Fixed private message handling. It used some old code that
499 caused the client to crash. Affecte file is
500 lib/silcclient/client_prvmsg.c.
502 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
504 * Added function silc_client_add_channel,
505 silc_client_replace_channel_id, and removed functions
506 silc_client_new_channel_id and silc_idlist_get_channel_by_id
509 * Added cross reference of the joined channels to the
510 SilcClientEntry, and changed the SilcChannelEntry's
511 users list to SilcHashTable. The affected files are
512 lib/silcclient/idlist.[ch].
514 * Fixed a bug in hash table tarversing. While the hash table
515 is traversed with SilcHashTableList the table must not be
516 rehashed. It is now guaranteed that auto rehashable tables
517 are not rehashed while tarversing the list. Also defined that
518 silc_hash_table_rehash must not be called while tarversing
519 the table. Added function silc_hash_table_list_reset that must
520 be called after the tarversing is over. The affected files are
521 lib/silcutil/silchashtable.[ch].
523 * Changed all hash table traversing to call the new
524 silc_hash_table_list_reset in server and in client library.
526 * Added function silc_client_on_channel to return the
527 SilcChannelUser entry if the specified client entry is joined
528 on the specified channel. This is exported to application as
529 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
531 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

534 server. The notify for mode change must be sent always and
535 not only if !cmd->pending. Affected file silcd/command.c.
537 * Fixed the WHOWAS command's reply sending to support the
538 lists correctly. Affected file silcd/command.c.
540 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
542 * When sending JOIN command to router for processing the
543 sender's old command identifier was not saved back to the
544 sender's command context, fixed now. The affected file is
547 * Create the key in JOIN command of the router did not return
548 the channel key, added check for this. Affected file is
551 * Fixed a channel ID update bug in JOIN command reply. Do
552 not directly upgrade the ID but call the function
553 silc_idlist_replace_channel_id if the ID was changed.
554 Affected file silcd/command_reply.c.
556 * Fixed memory leaks from command calling if it would fail.
557 Affected file silcd/command.c.
559 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
561 * Applied patches from cras:
563 Memory leak fixes around libaries, irssi window resize fix,
564 new silclist.h and silcdlist.h, all extern inline changed to
567 * Removed dotconf from lib/dotconf, not needed anymore.
569 * Removed TRQ from lib/trq, not needed anymore.
571 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
572 with server connections. Later this will be configurable
573 in config file after new config file is done. Affected file
576 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
578 * Fixed a crash in server related to channel announcements.
579 Affected file silcd/server.c.
581 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
583 * Fixed memory leaks in silc_server_create_new_channel*
584 functions. Affected file silcd/server.c.
586 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
587 which ID was changed. This way the router will send the
588 user list for the channel again, and server won't be in
589 desync in some rare circumstances. Affected file is
590 silcd/packet_receive.c.
592 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
594 * Check for NULL socket pointer in the function
595 silc_server_packet_send_to_channel_real. Affected file
598 * Fixed the BAN notify handling to correctly remove ban
599 list. Affected file silcd/packet_receive.c.
601 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
603 * Fixed some header addition to Toolkit distribution in
604 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
606 * Added lib/silcclient/client_ops_example.h as an template
607 file for application programmers to quickly start using
608 the SilcClientOperation functions in their application.
609 Updated the lib/silcclient/README as well to tell about this
610 nice file made available.
612 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
614 * Call silc_server_remove_from_channels when removing client
615 entry when NO_SUCH_CLIENT_ID was received. Affected file
616 is silcd/command_reply.c.
618 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
620 * Added server & router operator statistics updating. Affected
621 file silcd/packet_receive.c and silcd/command.c.
623 * Fixed the SERVER_SIGNOFF notify handling on normal server
624 not to save the history information for clients. Same was
625 fixed earlier in remove_clients_by_server function, but not
626 here. Affected file silcd/packet_receive.c.
628 * Raised the default connection-retry count from 4 to 7 in
629 server. Affected file silcd/server.h.
631 * Cancel any possible reconnect timeouts when we start the
632 key exchange. Affected file silcd/server.c.
634 * Do not reconnect on connection failure when SCONNECT was
635 given. Affected files silcd/server.[ch].
637 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
639 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
641 * Fixed the NICK command to always give the unformatted
642 nickname to the one giving the NICK command. If unformatted
643 nickname is cached already it will be formatted and the
644 local entry will always get the unformatted nickname.
645 Affected file lib/silcclient/idlist.c.
647 * Fixed some double frees from client library commands.
648 Affected file is lib/silcclient/command.c.
650 * Fixed CUMODE command in server to assure that no one can
651 change founder's mode than the founder itself, there was a
652 little bug. Affected file silcd/command.c.
654 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
656 * Removed the SilcClientCommandDestructor from the client
657 libary, it is not needed anymore. Affected files are
658 lib/silcclient/silcapi.h, command[_reply].[ch],
659 client_notify, idlist.c.
661 * Fixed GETKEY command to first resolve client, and then
662 resolve the server only if the client was not found, instead
663 of resolving both at the same time. Affected file is
664 lib/silcclient/command.c.
666 * Added silc_client_start_key_exchange_cb and lookup the
667 remote hostname and IP address before starting the key
668 exchange with server. The affected file is
669 lib/silcclient/client.c.
671 * The server's public key is now saved using the IP address
672 of the server and not the servername for the filename.
673 The hostname public key filename is checked as an fall back
674 method if the IP address based filename is not found.
676 Fixed the GETKEY command to save the fetched server key
679 Print the remote server's hostname now when new key is
680 received during connection process. Affected file is
681 irssi/src/silc/core/client_ops.c.
683 * Return always our own public key to the client if it asks
684 for it with GETKEY command. Affected file silcd/command.c.
686 * Removed the use_auto_addr variable from default config
687 file since it was in wrong section. Affected file is
690 * Fixed TOPIC_CHANGE notification to not route it when it
691 was sent using silc_server_send_notify_to_channel function.
692 Affected file silcd/command.c.
694 * Fixed silc_server_send_notify_kicked to send the kicker's
695 Client ID also, it was missing. Affected files are
696 silcd/command.c, silcd/packet_send.[ch].
698 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
700 * Do not save client history information in SERVER_SIGNOFF.
701 Fixes the bug in normal server that it does not detect
702 the client becoming valid after the server becomes back
703 online. Affected file silcd/server_util.c.
705 * Added `sock_error' field into the SilcSocketConnection
706 context. When error occurs during socket operation (read
707 or write) the error is saved. Added also new function
708 silc_socket_get_error to return human readable socket error
709 message. Affected files are lib/silcutil/silcsockconn.[ch],
710 lib/silcutil/unix/silcunixsockconn.c, and
711 lib/silcutil/win32/silcwin32sockconn.c.
713 * The server now prints the socket error message in the
714 signoff for client. Affected file silcd/server.c.
716 * Fixed the `created' channel information sending from router
717 to server in JOIN command. Checks now whether the channel
718 really was created or not and set it according that.
720 Fixed the JOIN command to use the client entry's current
721 ID during the joining procedure instead of the one it sent
722 in the command (it is checked though), since it can change
723 between the packet processing and command processing, and
724 would just case unnecessary pain in the client end. Affected
725 file silcd/command.c.
727 * Fixed a channel key payload sending to use correct channel
728 ID when the server was forced to change the channel's ID by
729 router. Router sent the key payload with the old Channel ID.
730 Affected file silcd/packet_receive.c.
732 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
734 * Call silc_server_save_channel_key only if the key payload
735 was provided in the JOIN command's command reply. Affected
736 file silcd/command_reply.c.
738 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
740 * Fixed silc_mp_sizeinbase to return the value correctly with
741 MPI. Affected file lib/silcmath/mp_mpi.c.
743 * Fixed the stop_server signal to correctly stop the scheduler
744 and gracefully stop the server when SIGTERM or SIGINT signals
745 are received. Affected file silcd/silcd.c.
747 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
749 * Simple handling of TERM and HUP signals. Also added some log
750 flushing call around. Affected file is
753 * Fixed small bugs in silclog.c. Now buffering output will take
754 effect after 10 seconds since startup: This will ensure that
755 no important startup messages are lost. Also output redirection
756 will preserve original format ([Date] [Type] message).
757 Affected file is lib/silcutil/silclog.c.
759 * Added two options to the config file, in the logging section:
760 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
761 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
763 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
765 * Do not print the warning about log files not being initialized
766 more than once to avoid excess logging. Affected file is
767 lib/silcutil/silclog.c.
769 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
770 the SIM copying in make install in Makefile.am.pre.
772 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
774 * Rewritten silclog APIs. Globally interesting changes follows:
775 silc_log_set_files() changed to silc_log_set_file().
776 silc_log_set_callbacks() changed to silc_log_set_callback().
777 ROBOdoc documented silclog header file.
778 SilcLogCb now returns bool to wether inihibit the default
779 handler or not (to keep the old behaviour return always TRUE).
780 The new APIs should also fix the problem of the
781 silcd_error.log file that was written in the current directory.
784 Log files streams will remain opened after silc_log_set_file()
785 call, means less CPU usage notably on high traffic servers.
786 File streams are now full buffered, and flushed to the disk
787 every 5 minutes, lesses HD activity and CPU usage.
788 Messages can be redirected, allowing admins to configure
789 one single logfile for all server messages.
790 the silc_log_quick global variable to activate fast-logging.
791 Affected files lib/silcutil/silclog.[ch]
793 * Changed some code to conform new silclog APIs. Affected
794 files are doc/example_silcd.conf.in, silcd/server.c
795 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
798 * Fixed a memory leak that could occur in some situations.
799 Affected file silcd/serverconfig.c.
801 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
803 * Added the silc_client_del_client to remove the client from
804 all channels as well. Affected file lib/silcclient/idlist.c.
806 * Fixed the client library to correctly remove the client
807 from all channels when the client entry is being destroyed.
808 Affected file lib/silcclient/client_notify.c, command.c.
810 * Added auto-nicking support to the client library. If the
811 applicatio now sets client->nickname it will be sent to the
812 server after connecting by the library. This way for example
813 SILCNICK (or IRCNICK) environment variables will have effect
814 and always change the nickname automatically to whatever
815 it is wanted. Affected file lib/silcclient/client.[ch].
817 * Renamed silc_server_command_bad_chars to the
818 silc_server_name_bad_chars and moved it to the
819 silcd/server_util.[ch]. Added also new function
820 silc_server_name_modify_bad to return nickname that
821 includes bad characters as new nickname without those
822 bad characters. This check and modify is now used in
823 silc_server_new_client when the username is initially set
824 as nickname, so it must be checked to be valid nickname.
825 Affected file silcd/packet_receive.c.
827 * The nickname length is now taken from the packet for real
828 and not trusted to strlen() since it clearly can return
829 wrong length for nickname including bad characters. This
830 also applies to channel names. Affected file silcd/command.c.
832 * Removed the lib/silcsilm/modules directory. Modules are now
833 compiled into the lib/silcsim. Fixed the copying of the
834 modules to follow symbolic links in Makefile.am.pre.
836 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
838 * Fixed silc_string_regexify list creation. Fixes bugs with
839 BAN and INVITE commands in server. The affected file is
840 lib/silcutil/unix/silcunixutil.c.
842 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
844 * Removed the command destructor entirely from the server's
845 command and command reply routines. It is not needed, and
846 its usage was buggy and caused crashes. Affected files are
847 silcd/command[_reply].[ch].
849 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
851 * Cancel protocol and NULL sock->protocol if timeout
852 occurred during protocol. Affected file silcd/server.c.
854 * Cancel protocol timeouts always before calling the final
855 callback, to assure that after final callback is called
856 no other state will be called for the protocol anymore.
857 Affected file silcd/protocol.c.
859 * Print error log if incoming connection configuration could
860 not be found. Affected file silcd/server.c.
862 * Fixed JOIN command to correctly save the founder mode
863 to the client on normal SILC server, when the channel
864 was created by the router. Affected file silcd/command.c.
866 * Fixed LIST command (hopefully) to send correct reply
867 packets. Affected file silcd/command.c.
869 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
871 * The silc_packet_receive_process now returns FALSE if the
872 read data was invalid packet, and TRUE if it was ok.
874 The server now checks that if unauthenticated connection
875 sends data and its processing fails the server will close
876 the connection since it could be a malicious flooder.
878 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
880 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
882 * Make sure the warning about error opening a log file is
883 printed only once and not everytime it fails (produces
884 too much useless log). Affected file lib/silcutil/silclog.c.
886 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
888 * Made the silc_server_daemonise() function more readable.
889 Affected file silcd/server.c.
891 * Pid file is now optional, the user may comment it out from
892 the config file. Removed define SILC_SERVER_PID_FILE, we
893 don't need a default any longer. Affected file
894 configure.in.pre, lib/Makefile.am.pre.
896 * Make some use of the pid file. The server now dies at startup
897 if it detects a valid pid file on his path. The server would
898 die anyway in this circumstance, because of the bind() failure.
899 Affected file silcd/silcd.c.
901 * No longer compiling lib/dotconf.
903 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
905 * Fixed JOIN command parsing not to crash. Affected file
906 lib/silcclient/command.c.
908 * Fied the NICK_CHANGE notify to add the new client entry
909 even it is resolved. This removes an <[unknown]> nick
910 thingy bug in the client. Affected file is
911 lib/silcclient/client_notify.c.
913 * Do not try to allocate 0 bytes (efence does not like it)
914 in lib/silccore/silccomand.c when encoding payload.
916 * Do not take IRCNICK as nickname in Irssi SILC client since
917 it is not possible to set nickname before hand connecting
918 the server (TODO has an entry about adding auto-nicking
921 * Changed the silc_server_command_pending to check whether
922 there already exists an pending entry with the specified
923 command, command identifier and pending callback. This is
924 to fix IDENTIFY and WHOIS related crashes that may register
925 multiple pending commands with same identifier. Affected
926 file silcd/command.c.
928 * Fixed the server to reconnect to the router even if it
929 was already reconnecting and EOF was received. This to
930 fix a possibility that the server wouldn't ever try to
931 auto-reconnect to the router. Affected file silcd/server.c.
933 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
935 * Fixed the server's password authentication to use the
936 length of the locally saved password, and not the one
937 sent in the packet. Affected file silcd/protocol.c.
939 * Fixed same password authentication problem in the
940 Authentication Payload handling routines in
941 lib/silccore/silcauth.c.
943 * Yet another password authentication problem fixed with
944 channel password handling in silcd/command.c.
946 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
948 * If first character of string in silc_parse_userfqdn is '@'
949 then do not parse it. Affected file is
950 lib/silcutil/silcutil.c.
952 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
954 * Fixed minor bug in IDENTIFY command reply sending, which
955 caused various weird problems during JOIN when it was
956 resolving names for users. Affected file silcd/command.c.
958 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
960 * Fixed the IDENTIFY command reply sending to chech better valid
961 clients. It was possible to send incomplete list of replies.
962 Affected file silcd/command.c.
964 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
966 * Added silc_client_command[s]_[un]register functions now to
967 dynamically register the commands in client library. Removed
968 the static table of commands. This allows the client library
969 to call commands without causing the application to know about
970 what commands library has called.
972 Removed the INFO command reply kludge to detect when the command
973 was called by library. Now library use its own command reply
974 function for INFO command.
976 Added function silc_client_command_call to call a command.
977 Application can use it to call command, not access the structure
980 Now all commands that are sent by the client library (not
981 explicitly sent by application) use own command reply functions.
983 Affected files around lib/silcclient/ and in
984 irssi/src/silc/core/.
986 * Fixed the WHOIS command reply sending to chech better valid
987 clients. It was possible to send incomplete list of replies.
989 Fixed the WHOIS and IDENTIFY to send the request to router
990 if normal server did not do it and did not find any results.
992 Affected file silcd/command.c.
994 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
996 * Moved the internal data from SilcClient context into its
997 own file, not accesible to application. Affected files
998 lib/silcclient/client.h and lib/silcclient/client_internal.h,
999 and other files in client library.
1001 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1003 * Added doc/examples installation target in Makefile.am.pre.
1006 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1008 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1009 commands the found client entry will be removed from the
1010 cache, after notifying application about the error. Affected
1011 file lib/silcclient/command_reply.c.
1013 * Changed the /MSG to check for exact nickname user gave, and
1014 not let `nick' match `nick@host' if it is only one found. Now,
1015 user must type the exact nickname (like nick@host2) even if
1016 there are no more than one same nicks found. This is to avoid
1017 a possibility of sending nickname to wrong nickname since
1018 `nick' could match `nick@host'. Affected file is
1019 irssi/src/core/silc-servers.c.
1021 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1023 * Do not print "you are now server operator" or similar when
1024 giving /away command. Affected files are
1025 irssi/src/silc/core/client_ops.c, silc-servers.h.
1027 * Made the silc_server_command_pending_error_check to send
1028 the same command reply payload it received back to the
1029 original sender of the command. This way all arguments
1030 that was received by the server will be received by the
1031 client too. Affected file silcd/command.c.
1033 * Added the silc_idcache_add to return the created cache entry
1034 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1036 * Add global clients to expire if they are not on any channel.
1037 This is because normal server will never know if they signoff
1038 if they are not on any channel. The cache expiry will take
1039 case of these entries. This is done by normal servers only.
1040 The affected files are silcd/command_reply.c,
1041 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1043 * If server receives invalid ID notification for WHOIS or
1044 IDENTIFY and the ID exists in the lists, it is removed.
1045 Affected file silcd/command_reply.c.
1047 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1048 in client then client entry that it matches is searched and
1049 the nickname is printed on the screen for user. Affected
1050 file irssi/src/silc/core/client_ops.c.
1052 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1054 * Use cache entry expire time in the LIST command reply to
1055 purge old entries from the cache after the LIST command
1056 reply has been received. This way we don't have non-existent
1057 entries in the cache for too long. Affected file is
1058 silcd/command_reply.c.
1060 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * If we are normal server, and we've not resolved client info
1063 in WHOIS or IDENTIFY from router, and it is global client,
1064 we'll check whether it is on some channel. If it is not
1065 then we cannot be sure about its validity and will resolve it
1066 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1067 file silcd/command.c.
1069 * Search channel by name (if possible) rather than by ID
1070 in IDENTIFY command's command reply. Affected file is
1071 silcd/command_reply.c.
1073 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1075 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1076 Updated specs and implemented it. Affected file silcd/command.c,
1077 silcd/packet_send.c and silcd/packet_receive.c.
1079 * Implemented the <founder auth> payload handling in the JOIN
1080 command. If provided all conditions for channel joining
1081 except requirement to provide correct passphrase can be
1082 overrided by the channel founder. Updated the protocol specs.
1083 Affected file silcd/command.c.
1085 Added support for founder auth in JOIN command in client
1086 library. Fixed the parsing of the JOIN command now to support
1087 all options as they should be. The affected file is
1088 lib/silcclient/command.c.
1090 * Optimized the WHOIS and IDENTIFY commands to send the request
1091 to router only if it includes nicknames or other names. If
1092 they include only IDs then check the local cache first before
1093 routing. Affected file is silcd/command.c.
1095 * Added channels topic announcements. Affected file is
1096 silcd/packet_receive.c and silcd/server.c.
1098 * Fixed the silc_server_send_notify_topic_set to really destine
1099 the packet to channel. Affected file silcd/packet_send.c.
1101 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1102 library. Affected file lib/silcclient/client_notify.c.

1124 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1126 * Update the client entry context in the ID cache after
1127 nick change. Affected file lib/silcclient/command.c.
1128 Fixes the CUMODE command when regaining founder privileges,
1129 and a little WHOIS problem.
1131 * Fixed silc_net_gethostbyname to correctly call the
1132 inet_ntop. Affected file lib/silcutil/silcnet.c.
1134 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1136 * Added IPv6 support checking to the configure.in.pre, added
1137 also --enable-ipv6 option to override the check. Affected
1138 file configure.in.pre.
1140 * The silc_thread_create now calls the start function
1141 directly if threads support is not compiled in. Removes
1142 ugly #ifdef's from generic code. Affected files are
1143 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1145 * Added silc_net_gethostby[name/addr]_async to asynchronously

1164 * Fixed LIST command reply sending in server. Affected file
1167 * Server now sends the kicker's client ID in the KICK notify
1168 to the kicked client. Affected file silcd/command.c.
1170 * The client library now parses the kickers client ID and
1171 UI displays it. Affected files lib/silcclient/client_notify.c
1172 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1174 * Made all payload parsing function prototypes consistent.
1175 They all take now const unsigned char * and uint32 pair as
1176 the payload data instead of SilcBuffer. Changes all around
1177 the source tree. Other unsigned char* -> const unsigned char*
1178 changes around the tree as well.
1180 * Optimized SFTP client and server packet sending not to
1181 allocate new buffer for each packet but to recycle the
1182 first allocated buffer. Affected files are
1183 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1185 * Optimized the SFTP client to use SilcList instead of
1186 SilcDList for requests, because it is faster. Affected file
1187 is lib/silcsftp/sftp_client.c.
1189 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1190 into lib/silccore/silcid.[ch].
1192 Renamed silcpayload.[ch] into silcargument.[ch].
1194 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1196 * If client entry is deleted with active key agreement
1197 session, abort the session.
1199 The silc_client_abort_key_agreement now calls the completion
1200 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1202 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1205 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1207 * Don't use __restrict in older GCC's. Affected file is
1208 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1210 * silc_net_localhost now attempts to reverse lookup the
1211 IP/hostname. Affected file lib/silcutil/silcnet.c.
1213 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1214 command. It can be used to gain founder privileges at
1215 the same time when joining the channel.
1217 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1218 kicker's client ID as well. Updated protocol specs.
1220 Defined that the server must send SILC_COMMAND_IDENTIFY
1221 command reply with error status to client who sent
1222 private message with invalid client ID.
1224 Updated the protocol specification.
1226 * Added silc_server_send_command_reply to send any
1227 command reply. Affected file silcd/packet_send.[ch].
1229 * Added silc_id_payload_encode_data to encode ID payload
1230 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1232 * The server now send IDENTIFY command reply with error
1233 status if client ID in private message is invalid. Affected
1234 file silcd/packet_receive.c.
1236 * Save the server key file with server's IP address in
1237 the filename instead of hostname. The affected file is
1238 irssi/src/silc/core/client_ops.c.
1240 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1242 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1245 * Added libtool support for compiling shared objects in
1246 lib/silcsim. Affected file configure.in.pre and
1247 lib/silcsim/Makefile.am. Original patch by cras.
1249 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1251 * Pid file configuration, and server's config file fixes
1252 patch by toma. Updated CREDITS file.
1254 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1256 * Fixed silc_client_channel_message to not try to decrypt
1257 the message twice if it resolved the destination client
1258 information. This could cause of dropping one channel
1259 message. Affected file lib/silcclient/client_channel.c.
1261 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1264 lib/silcclient/client.c. This function is used when the SILC
1265 Client is run under some other scheduler, or event loop or
1266 main loop. On GUI applications, for example this may be
1267 desired to used to run the client under the GUI application's
1268 main loop. Typically the GUI application would register an
1269 idle task that calls this function multiple times in a second
1270 to quickly process the SILC specific data.
1272 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1274 * Fixed silc_server_drop() for dropping the supplementary
1275 groups as well, this could cause a security hole on some
1278 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1280 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1283 * Write PID file after dropping privileges. Added -F option
1284 to run server on foreground. A patch by debolaz.
1285 Affected files silcd/server.c, silcd/silcd.c.
1287 * Fixed MOTD to return the MOTD file server name. Affected
1288 file silcd/command.c.
1290 * Added INFO command reply handling to the Irssi SILC Client.
1291 Affected file irssi/src/silc/core/client_ops.c.
1293 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1295 * Fixed the silc_idcache_list_* routines to really support
1296 the dynamic list. Fixes a crash. Affected file is
1297 lib/silccore/silcidcache.c.
1299 * Fixed the LIST command reply to really call LIST command's
1300 pending callbacks. Affected file silcd/command_reply.c.
1302 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * Update conn->local_entry->nickname after giving NICK
1305 command. Affected file lib/silcclient/command.c.
1307 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1309 * Added the [pid] option to the silcd configuration file
1311 Affected files: serverconfig.[ch] and silcd.c
1313 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1315 * Save fingerprint in WHOIS command reply in server.
1316 Affected file silcd/command_reply.c.
1318 * Fixed NICK commands pending callback registration.
1319 Affected file lib/silcclient/command.c.
1321 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1323 * Use ++server->cmd_ident when sending commands in server,
1324 instead of random number. Affected file silcd/command.c.
1326 * Fixed GETKEY command reply to call actually GETKEY pending
1327 command callbacks. Affected file silcd/command_reply.c.
1329 * A bit stricter check for nicknames. Check for same nickname
1330 in NICK command also. Affected file silcd/command.c.
1332 * Do not call INFO command everytime client ID changes, only
1333 during first connecting. Affected file lib/silcclient/client.c.
1335 * Set the new nickname only after successful command reply for
1336 NICK command is returned by server. Affected file
1337 lib/silcclient/command.c.
1339 * Remove nicknames from nicklist during server_signoff notify.
1340 Should fix /NAMES bit more. The affected file is
1341 irssi/src/silc/core/silc-channels.c.
1343 * Added `fingerprint' field to the SilcIDListData in the
1344 silcd/idlist.h to hold the fingerprint of the client's
1347 Send the fingerprint of the client's public key in WHOIS
1350 Affected files silcd/command.c, and silcd/idlist.[ch].
1352 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1353 create fingerprint from given data.
1355 * Show the fingerprint of the client's public key in WHOIS.
1356 Affected files irssi/src/module-formats.[ch] and
1357 irssi/src/silc/core/client_ops.c.
1359 * Format the multiple same nicknames also during JOIN and
1360 NICK_CHANGE notifys. Affected file is
1361 lib/silcclient/client_notify.c.
1363 * Do not print error on screen for invalid private message
1364 payload since it can come if someone is sending private
1365 messages with wrong key. Affected file
1366 lib/silccore/silcprivate.c.
1368 * Fixed multiple concurrent /PING crash. Affected file
1369 lib/silcclient/command.c.
1371 * Changed the wrong ID encoding. All IP addresses must be
1372 in MSB first order in encoded format. They were encoded
1373 wrong and was in LSB format. Affected files are
1374 silcd/serverid.c, lib/silcutil/silcutil.c.
1376 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1378 * Call the `connect' client operation through the scheduler
1379 in case of error. Affected file lib/silcclient/client.c.
1381 * Call the `failure' client operation even if the error
1382 occurred locally during a protocol. Affected file is
1383 lib/silcclient/protocol.c.
1385 * Added support of sending LIST command to router from normal
1386 server. This way normal server can get list of all channels
1387 in the network too. Fixed the channel list sending in the
1388 server too. Affected files are silcd/command.c, and
1389 silcd/command_reply.[ch].
1391 * Added silc_server_update_channels_by_server and
1392 silc_server_remove_channels_by_server. They are used during
1393 disconnection of primary router and in backup router protocol.
1394 Affected file silcd/server_util.[ch], silcd/server.c and
1395 silcd/server_backup.c.
1397 * Fixed channel adding to global list in IDENTIFY command
1398 reply in server. Affected file silcd/command_reply.c.
1400 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1402 * If the incoming packet type is REKEY or REKEY_DONE process
1403 that packet always synchronously. Fixes yet another MAC
1404 failed error on slow (dialup) connections. Affected file
1405 lib/silcclient/client.c and silcd/server.c.
1407 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * Call check_version SKE callback for initiator too. Affected
1410 file lib/silcske/silcske.c.
1412 * Implemented fix for security hole found in the SKE that was
1413 fixed in the specification few days back; the initiator's
1414 public key is now added to the HASH value computation.
1415 Added backwards support for the old way of doing it too, for
1416 old clients and old servers. Affected file is
1417 lib/silcske/silcske.c.
1419 * Enabled mutual authentication by default in SKE. If initiator
1420 is not providing mutual authentication the responder will
1421 force it. This will provide the proof of posession of the
1422 private key for responder. The affected files are
1423 lib/silcclient/protocol.c and silcd/protocol.c.
1425 * Do not cache anymore the server's public key during SKE.
1426 We do mutual authentication so the proof of posession of
1427 private key is done, and if the server is authenticated in
1428 conn auth protocol with public key we must have the public
1429 key already. Affected file silcd/protocol.c.
1431 * Added new global debug variable: silc_debug_hexdump. If
1432 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1433 file lib/silcutil/silclog.[ch].
1435 * Fixed compilation warning due to char * -> const char *.
1436 Affected files lib/silcutil/silcnet.h, and
1437 lib/silccore/silcauth.[ch].
1439 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1441 * Fixed CMODE command when new channel key was created. If
1442 the creation failed the old key was removed. Next time giving
1443 same command would crash the server since the old key was
1444 freed already. Affected file silcd/command.c.
1446 * Fixed the silc_server_announce_get_channels to not crash
1447 on reconnect. Affected file silcd/server.c.
1449 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1451 * Added silc_log_set_debug_string function to set a regex
1452 string to match for debug output. Only the function names,
1453 or filenames matching the given debug string is actually
1454 printed. This way it is possible to filter out those debug
1455 strings that user is not interested in.
1457 Fixed a bug in silc_string_regexify.
1459 Affected files lib/silcutil/silclog.[ch], and
1460 lib/silcutil/unix/silcunixutil.c.
1462 * Changed the -d options in both server and Irssi SILC client
1463 to take the debug string as argument. Affected files
1464 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1466 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1468 * Added silc_hash_babbleprint to create a Bubble Babble
1469 Encoded fingerprint. The encoding is developed by Antti
1470 Huima (draft-huima-babble-01.txt), and it creates human
1471 readable strings out of binary data. Affected file
1472 lib/silccrypt/silchash.[ch].
1474 * Print the babble print now in addition of fingerprint as well
1475 in Irssi SILC client. Affected files are
1476 irssi/src/fe-common/silc/module-formats.[ch],
1477 irssi/src/fe-common/silc/core/client_ops.c.
1479 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1481 * Fixed a security problem found in SKE. The initiator's
1482 public key too is now added to the HASH hash value creation
1483 which is signed by the responder to create the SIGN value.
1484 This will prevent anyone in the middle to lie to the responder
1485 about the initiator's public key. If this is done now, the
1486 man in the middle will get caught. Updated the protocol
1489 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1491 * Better installation directory handling. Configure module
1492 paths and other paths automatically to example_silc* files
1493 in doc/. A patch by toma.
1495 * Fixed compiler warning from MPI library, and from SILC RNG.
1498 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1499 It can be configured with ./configure. A patch by toma.
1501 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1503 * Find correct make to use in prepare-clean. A patch by
1504 toma. Affected file prepare-clean.
1506 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1508 * Added irssi variables use_auto_addr, auto_bind_ip,
1509 auto_bind_port and auto_public_ip.
1511 * Changed the interface for silc_client_send_key_agreement
1512 in lib/silcclient/silcapi.h
1516 irssi/src/silc/core/silc-core.c
1518 lib/silcclient/silcapi.h
1519 irssi/src/silc/core/silc-channels.c
1520 lib/silcclient/client_keyagr.c
1523 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1525 * Added silc_pkcs_public_key_compare to compare two
1526 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1528 * Check that the client who set the founder mode on the
1529 channel is the same client that is giving the founder
1530 mode to itself. It is done by comparing the saved public
1531 key (it is saved even in the authentication is passphrase).
1532 Affected file silcd/command.c.
1534 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1536 * Do not process packet for disconnected socket connection.
1537 Affected file lib/silccore/silcpacket.c.
1539 * Process the DISCONNECT packet through scheduler in the
1540 client library. Affected file lib/silcclient/client.c.
1542 * Fixed the silc_client_packet_parse to not to increase
1543 the packet sequence number if the conn->sock and the
1544 current socket connection is not same. This can happen
1545 for example during key agreement when the conn includes
1546 multiple socket connections (listeners). Affected file
1547 lib/silcclient/client.c.
1549 * The sender of the file transfer request now provides also
1550 the pointer (listener) for the key exchange protocol. If
1551 the listener cannot be created then it sends empty key
1552 agreement and lets the receiver provide the listener.
1554 Added `local_ip' and `local_port' arguments to the
1555 silc_client_file_send. If they are provided they are used,
1556 if not then it will attempt to find local IP address, if
1557 not found or bind fails then the remote client will provide
1560 Affected files are lib/silcclient/client_ftp.c and
1561 lib/silcclient/silcapi.h.
1563 * Extended the FILE SEND command to support defining the
1564 local IP and port for key exchange listener. They are
1565 optional. Affected file irssi/src/silc/core/silc-servers.c.
1567 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1569 * Defined to WHOIS command reply the sending of fingerprint
1570 of the client's public key (if the proof of posession of the
1571 corresponding private key is verified by the server).
1572 Updated to the protocol specification.
1574 * Added support of receiving the client's public key's
1575 fingerprint in command reply in client library. Affected
1576 file is lib/silcclient/command_reply.c, and
1577 lib/silcclient/idlist.[ch].
1579 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1581 * Do not send over 128 chars long nickname to the server
1582 in NICK command. Affected file lib/silcclient/command.c.
1584 * Do not send over 256 chars long channel names to the server
1585 in JOIN command. Affected file lib/silcclient/command.c.
1587 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1589 * Assure that silc_server_close_connection cannot be called
1590 twice for same socket context. Affected file is
1593 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Send error message to application if opening file for
1596 writing during file transfer fails. Affected file is
1597 lib/silcclient/client_ftp.c.
1599 Remove all file transfer sessions for a client that we're
1600 removing from ID cache.
1602 Affected file is lib/silcclient/client_ftp.c.
1604 * Fixed silc_net_addr2bin to return correct address. Affected
1605 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1607 * Fixed file transfer session removing on signoff notify.
1608 Affected file irssi/src/silc/core/silc-servers.c.
1610 * Added the SilcClientFileError to be returned in the monitor
1611 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1612 Affected file lib/silcclient/silcapi.h.
1614 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1616 * Fixed a crash in silc_client_ftp_free_sessions and
1617 silc_client_ftp_session_free_client. Affected file
1618 lib/silcclient/client_ftp.c.
1620 * Added `disabled' field in the SilcChannelEntry in the server
1621 to indicate if the server entry is disabled. Affected file
1622 silcd/idlist.h, silcd/command[_reply].c.
1624 * SILC server adds now /var/run/silcd.pid everytime it is
1625 started. Affected file silcd/silcd.c.
1627 * Added silc_server_packet_send_clients to send a packet to
1628 the provided table of client entries. Affected file
1629 silcd/packet_send.[ch].
1631 * Fixed a crash in client resolving in client_prvmsg.c in
1632 client library. Affected file lib/silcclient/client_prvmsg.c.
1634 * Do not actually remove the client directly from ID cache
1635 during SERVER_SIGNOFF, but invalidate it. This way we
1636 preserve the WHOWAS info for the client. Affected file
1637 silcd/server_util.c.
1639 * Fixed SERVER_SIGNOFF notify handling in the server. The
1640 server is now able to process incoming SERVER_SIGNOFF notify
1641 for a server that it doesn't even know about. It will remove
1642 the clients provided in the notify. Affected file
1643 silcd/packet_receive.c.
1645 * Check for partial packet in data queue after every packet that
1646 was found from the queue. Return and wait for more data if
1647 there is partial data in queue. Affected file is
1648 lib/silccore/silcpacket.c.
1650 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1665 irssi/src/fe-common/silc/module-formats.[ch].
1667 * Wrote a help file for FILE command.
1669 * Added silc_rng_global_get_byte_fast to get not-so-secure
1670 random data as fast as possible. Random data is read from
1671 /dev/urandom if available and from the SILC RNG if not
1672 available. It is used in padding generation. Affected file
1673 lib/silccrypt/silcrng.[ch].
1675 * All packets in client library are now processed synchronously.
1676 Optimized packet processing a lot. Affected file
1677 lib/silcclient/client.c.

1688 * Assure that silc_client_notify_by_server_resolve does not
1689 resolve the client information multiple times. If it cannot
1690 be found by the first it cannot be found at all. Affected
1691 file lib/silcclient/client_notify.c.
1693 * Fixed WHOWAS command reply calling. Affected file
1694 lib/silcclient/command_reply.c.
1696 * Removed all references to silc_idlist_get_client from the
1697 Irssi SILC client since that call is internal call used by
1698 the library. The Irssi SILC client will use now client
1699 retrieval functions found in silcapi.h.
1701 * Fixed a bug in resolving nickname info before sending
1702 private message. It used freed memory. Affected file
1703 irssi/src/silc/core/silc-servers.c.

1724 * Added silc_net_localip to return local host's IP address.
1725 Affected file lib/silcutil/silcnet.[ch].
1727 * If key exchange or rekey protocol is active for a connection
1728 parse all packets syncronously since there might be packets
1729 in packet queue that we are not able to process without first
1730 processing packets before them. Affected file silcd/server,
1731 lib/silcclient/client.c.
1733 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1734 whether library should continue processing the packet.
1735 Affected file lib/silccore/silcpacket.h.

1781 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1782 is incomplete and is being resolved, it won't be resolved
1785 Make sure also that USERS command reply does not resolve
1786 twice information. Affected file is
1787 lib/silcclient/command_reply.c.
1789 Make sure that silc_client_get_clients_by_list does not
1790 resolve twice same information.
1792 * Check for valid client->id in the silc_server_free_client_data.
1793 Affected file silcd/server.c.
1795 * Fixed /GETKEY nick@server not to crash if the server entry
1796 is not found. Affected file lib/silcclient/command.c.

1806 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Call the silc_server_udpate_servers_by_server in the
1809 primary router that comes back online in the backup resuming
1810 protocol. Otherwise it routes packets wrong. Affected file
1811 silcd/server_util.[ch], silcd/server_backup.c.
1813 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1815 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1816 lib/silcutil/silcbuffmt.[ch].
1818 * Redefined the SILC packet header to include the padding
1819 length. Affected file lib/silccore/silcpacket.[ch].
1821 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1822 length for maximum padding up to 128 bytes). Affected
1823 file lib/silccore/silcpacket.h.
1825 * Removed all backwards support for old 0.5.x MAC thingies.
1826 The SILC packet header change makes it impossible to be
1827 backwards compatible.
1829 * Send the ENDING packet with timeout in the backup resuming
1830 protocol. This is to assure that all routers has connected
1831 to the primary router. Affected file silcd/server_backup.c.
1833 * Changed the RNG to take the first IV from random data. It
1834 used to take it from zero actually. Changed the RNG also
1835 to use /dev/urandom during session. /dev/random is used
1836 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1838 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Changed the SILC packet header to have the first two bytes
1841 (the packet length) encrypted. Affected files aroung the
1842 code tree, lib/silccore/silcpacket.[ch]. Removed the
1843 SilcPacketCheckDecrypt callback. It is not needed anymore
1844 since the silc_packet_receive_process will determine now
1845 whether the packet is normal or special.
1847 * Implemented the unidirectional MAC keys. Affected files
1848 lib/silcske/silcske.c, silcd/protocol.c and
1849 lib/silcclient/protocol.c.
1851 * Implemented the packet sequence number to the MAC computation.
1852 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1853 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1854 lib/silcclient/protocol.c.
1856 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1858 * Allow backup router to announce servers. All servers
1859 announced by backup router are added to the global list
1860 automatically. Update hte server's socket to our primary
1861 router also when backup router announces a server.
1862 Affected file silcd/packet_receive.c.
1864 * Do not update the client->router in the function
1865 silc_server_udpate_clients_by_server if the client is on
1866 global list. We might fail to find any specific server
1867 for locally connected clients and local cell clients. They
1868 should still use the `from' and not `to' as client->router.
1869 This fixes backup router resuming protocol. Affected file
1870 silcd/server_util.c.
1872 * Decrease channel statistics count only if the channel
1873 deletion worked. Affected files are silcd/server.c and
1874 silcd/server_util.c.
1876 * Added silc_server_update_servers_by_server to update origin
1877 of all server entries. Used during backup router protocol.
1878 Affected files silcd/server_util.[ch], silcd/server.c. and
1879 silcd/backup_router.c.
1881 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1882 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1883 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1884 lib/silccrypt/silchmac.c.
1886 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1888 * Assure that router cannot reroute the same channel message
1889 to the sender. Affected file silcd/packet_receive.c.
1891 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Made better checks that the channel message is not sent
1894 to the router it came from. Affected file is
1895 silcd/packet_send.c. Fixed memory leak too.
1897 * Announce informations for incoming router connection, but
1898 only after checking if it is replaced by backup router.
1899 Affected file silcd/packet_receive.c.
1901 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1903 * Fixed the backup resuming protocol to work in multiple
1904 router environment. Affected file silcd/server_backup.c.
1906 * Route packet only to one router in the function
1907 silc_server_packet_send_to_channel. Affected file is
1908 silcd/packet_send.c.
1910 * Fixed silc_server_send_notify_dest to set the broadcast
1911 flag. Fixed the silc_server_send_notify_topic to actually
1912 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1913 Affected file silcd/packet_send.c.
1915 * Changed the SFTP Filesystem interface. Changed the
1916 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1917 the filesystem operation function. The SilcSFTPFilesystem
1918 is now a context that is allocated by all filesystem allocation
1919 functions and it already includes the operations structure
1920 and filesystem specific context. It is given as argument
1921 now to the silc_sftp_server_start. This made the interface
1922 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1923 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1925 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1927 * Changed the backup router adding and getting interfaces
1928 in the server. The router that will be replaced by the
1929 specified backup router is now sent as argument. Affected
1930 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1933 * Added silc_net_addr2bin_ne to return the binary form of
1934 the IP address in network byte order. Affected files
1935 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1937 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1939 * Check for existing server ID in silc_server_new_server
1940 and in silc_server_connect_to_router_final and remove the
1941 old entry if it exists. Affected file silcd/packet_receive.c,
1944 * Send the channel message always to only one router, either
1945 in upstream or downstream. Affected file is
1946 silcd/packet_send.c.
1948 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1951 protocol specification.
1953 * Removed one redundant channel key generation from normal
1954 server during joining procedure. Removed one redundant
1955 channel key sending from server to router during joining
1956 procedure. Affected file silcd/command.c.
1958 * Made minor bugfixes to the backup router resuming protocol.
1959 Affected file silcd/server_backup.c, server.c.

1964 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1967 * Implemented the backup resuming protocol that is used to
1968 resume the primary router position in the cell after the
1969 primary router comes back online. Affected files
1970 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1971 and silcd/server_util.[ch].
1973 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Sleep two (2) seconds after sending QUIT command to server.
1976 Affected file lib/silcclient/command.c.
1978 * Assure that if outgoing data buffer is pending do not force
1979 send any data. Affected file silcd/packet_send.c.
1981 * Assure that if outgoing data buffer is pending do not force
1982 send any data. Affected file lib/silcclient/client.c.
1984 * Implemented the backup router support when the primary router
1985 goes down. The servers and routers can now use the backup
1986 router as new primary router without loosing connectivity.
1988 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1991 in the server to indicate disabled entry. All data read
1992 from the connection will be ignored and no data is sent
1993 for entry that is disabled. Affected files are
1994 silcd/idlist.h, silcd/server.c.
1996 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1998 * Created SFTP client and server test programs in the
1999 lib/silcsftp/tests directory.
2001 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2003 * Implemented memory filesystem (virtual filesystem) for
2004 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2007 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * Implemented the SFTP (SSH File Transfer Protocol) to the
2010 lib/silcsftp. It includes SFTP client and SFTP server
2013 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2015 * Moved lib/silccore/silcprotocol.[ch] to the
2016 lib/silcutil library.
2018 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2019 take variable argument list pointer as argument. Affected
2020 file lib/silcutil/silcbuffmt.[ch].
2022 * Added silc_buffer_set function that is used to set data
2023 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2024 Affected file lib/silcutil/silcbuffer.h.
2026 * Changed various routines in the core library to use the new
2027 silc_buffer_set instead of allocating new buffer only for
2030 * Added 64-bit value formatting and unformatting support to the
2031 silc_buffer_[un]format routines. Affected file is
2032 lib/silcutil/silcbuffmt.[ch].
2034 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2035 to includes/bitmove.h.
2037 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2039 * Fixed channel user mode saving in client library. Affected
2040 file lib/silcclient/command[_reply].c.
2042 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2044 * Defined the file transfer to the SILC Protocol. Added
2045 new packet type SILC_PACKET_FTP and defined File Transfer
2046 Payload. The mandatory file transfer protocol is SFTP
2047 (SSH File Transfer Protocol). Affected file in addition
2048 of the internet draft is lib/silccore/silcpacket.h.
2050 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2051 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2052 is used as part of backup router protocol when the primary
2053 router of the cell is back online and wishes to resume
2054 the position as primary router.
2056 * Redefined the MAC generation keys in the protocol. The
2057 same key is not used anymore in both direction. Both
2058 direction will now use different keys for sending and
2059 receiving. This fixes a potential security flaw. This
2060 change causes incompatibilities in the protocol.
2062 * Redefined also the MAC computation from the packet.
2063 An packet sequence number is now added to the MAC
2064 computation. This prevents possible replay attacks against
2065 the protocol. This change too causes incompatibilities
2068 Added `sequence' field to the SilcPacketContext to hold
2069 the current sequence number for the packet.
2071 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * Added `created' field to the SilcIDListData in the file
2074 silcd/idlist.h to indicate the time when the entry was
2077 * Added `created' field to the SilcChannelEntry too. Affected
2078 file silcd/idlist.h.
2080 * Added `creation_time' aguments to all the announcement functions
2081 in the server. If it is provided then only the entries that
2082 was created after the provided time frame are actually
2083 announced. Affected file silcd/server.[ch].
2085 * The protocol says that the Channel ID's IP address must be
2086 based on the router's IP address. Added check for this in
2087 the silc_server_new_channel when processing incoming New Channel
2088 Payload. Affected file silcd/packet_receive.c.
2090 * Print out the correct version with --version in SILC client.
2091 Affected file irssi/src/silc/core/silc-core.c.
2093 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Fixed WHOWAS command to check for completnes of the client
2096 entry always, not just when the command is coming from client.
2097 Affected file silcd/command.c.
2099 * Added new function silc_server_packet_queue_purge to purge the
2100 outgoing data queue to the network. After the function returns
2101 it is guaranteed that the outgoing packet queue is empty.
2102 Affected file silcd/packet_send.[ch].
2104 * Purge the outgoing packet queue in the rekey protocol's final
2105 callback to assure that all rekey packets go to the network
2106 before quitting the protocol. Affected file silcd/server.c.
2108 * Added silc_client_packet_queue_parse as similar function as
2109 in server to the client library. The affected file is
2110 lib/silcclient/client.c.
2112 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * Splitted silcd/server.c and created silcd/server_util.[ch]
2115 for utility functions.
2117 * Added new socket flag SILC_SF_DISABLED to indicate that the
2118 connection is open but nothing can be sent to or received from
2119 the connection. Affected file lib/silcutil/silsockconn.[ch].
2120 The checking for disabled socket is checked in the low level
2121 silc_socket_write and silc_socket_read functions.
2123 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Allow only nicknames and channel names that fits into the
2126 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2128 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2130 * When processing JOIN command reply in server check that if
2131 the channel exists in our global list we'll move it the local
2132 list. Affected file silcd/command_reply.c.
2134 * Fixed the check whether client is joined on the channel already
2135 in JOIN command. Affected file lib/silcclient/command.c.
2137 * Fixed the JOIN command reply to check whether the channel
2138 already exists. Affected file lib/silcclient/command_reply.c.
2140 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2142 * Added silc_ske_status_string to map the SKE error numbers
2143 to readable strings. The affected files are
2144 lib/silcske/silcske[_status].[ch].
2146 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2148 * Do not show the private channels on the WHOIS channel list
2149 as it is not allowed by the protocol. The affected file is
2152 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Assure that the packet length digged from the actual packet
2155 is something sensible in the silc_packet_decrypt_rest_special
2156 in lib/silccrypt/silcpacket.c.
2158 * Free and NULL the allocated pointer in silc_hmac_alloc if
2159 the HMAC allocation fails. The affected file is
2160 lib/silccrypt/silchmac.c.
2162 * Print the selected security properties to the log files in
2163 the server. Affected file silcd/protocol.c.
2165 * Add SKE's reference counter even if calling the completion
2166 callback manually. Otherwise it goes negative, although it
2167 does not cause any problems. The affected file is
2168 lib/silcske/silcske.c.
2170 * Remove the client entry with short timeout after giving the
2171 KILL command. Affected file lib/silcclient/command.c.
2173 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2174 case all found clients are already disconnected (WHOWAS would
2175 found them) in the server. Affected file silcd/command.c.
2177 * Update the last_receive (time of last data received) to be
2178 updated only when received private or channel message so that
2179 the idle time showed in WHOIS makes more sense.
2181 * Added boolean field `valid' in to the SilcClientEntry in the
2182 client library to indicate whether the entry is valid or not.
2183 This fixes the nickname change bug on channel when changing
2184 the nickname to be same than the old (like nick to Nick) the
2185 nickname formatter doesn't set the new nick anymore to Nick@host.
2186 Affected file lib/silcclient/idlist.[ch].
2188 * Now actually fixed the nickname changing on disconnection.
2189 Added new function silc_change_nick to the Irssi SILC Client.
2190 Affected file irssi/src/silc/core/client_ops.c,
2191 irssi/src/silc/core/silc-nicklist.[ch].
2193 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Check that the public key exists in the GETKEY command before
2196 trying to encode it. Affected file silcd/command.c.
2198 * Print some notifications on received public keys with GETKEY
2199 command in the Irssi SILC Client. Affected files are
2200 irssi/src/fe-common/silc/module-formats.[ch],
2201 irssi/src/silc/core/client_ops.c.
2203 * Use IDENTIFY command to resolve the server information in the
2204 GETKEY command instead of INFO command. Affected file
2205 lib/silcclient/command.c.
2207 * All command reply functions in the client library now calls
2208 the pending command reply callbacks even if an error has
2209 occurred. The server has done this a long time and now it was
2210 time to move the client library to this as well. Now all
2211 errors can be delivered back to the pending command reply
2212 callbacks if necessary. Affected files are
2213 lib/silcclient/command[_reply].[ch].
2215 * Change the nickname on disconnection back to the username
2216 because in reconnect the server will enforce it to it anyway.
2217 Affected file irssi/src/silc/core/silc-servers.c.
2219 * Fixed a config file parsing bug in the Irssi SILC client.
2220 Affected file irssi/src/silc/core/clientconfig.c.
2222 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2224 * When printing the channel mode on JOIN, verify that the
2225 channel key and channel's HMAC are valid. Affected file
2226 irssi/src/silc/core/client_ops.c.
2228 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2230 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2231 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2232 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2234 * Removed channel key rekey task deleting from the function
2235 silc_server_save_channel_key. Affected file silcd/server.c.
2236 Added explicit timeout task context instead that is used to
2237 delete the task if we are registering a new task before the
2238 new task has elapsed.
2240 * When channel key rekey occurs the client library now saves
2241 the old channel key for a short period of time (10 seconds) and
2242 is able to use it in case some is still sending channel
2243 messages encrypted with the old key after the rekey. Affected
2244 file lib/silcclient/[idlist.h|client_channel.c].
2246 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Added check to the silc_server_new_id_real to not accept
2249 new ID if it is the sender's own ID. Affected file is
2250 silcd/packet_receive.c.
2252 * Assure that we do not announce ourself or the one we've
2253 sending our announcements when we're router and are announcing
2254 servers to our primary router. Affected file silcd/server.c.
2256 * Fixed silc_server_command_identify_check_client to assemble
2257 correct WHOIS packet. It send corrupted WHOIS packet and
2258 caused problem with router to router connections. Affected
2259 file silcd/command.c.
2261 Fixed also silc_server_command_whois_check the same way
2262 as for the IDENTIFY command.
2264 * Added new SilcIDListStatus to the server in the SilcIDListData
2265 structure. The status now includes the current status of
2266 the entry (like registered, resolved etc.). Affected file
2267 silcd/idlist.[ch]. Defined a bunch of different status types
2268 as well. This replaced the old boolean registered field as well.
2270 Added resolve_cmd_ident field to the SilcClientEntry structure
2271 too so that if the entry is for example being resolved so
2272 another command may attach to the same pending command reply
2273 without requiring to resolve the same entry again. This concept
2274 should optimize the WHOIS and the IDENTIFY resolving under
2275 heavy load by taking away unnecessary resolving for entries
2276 that are being resolved already.
2278 Added support for adding multiple pending commands for one
2279 command idenfier. Affected file silcd/command[_reply].[ch].
2281 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2282 before deleting the data. Otherwise the hash table will have
2283 freed data in comparison functions. Affected file is
2284 silcd/command_reply.c.
2286 * Fixed silc_idlist_replace_client_id to add the new entry to
2287 the cache with NULL nickname. Otherwise there will be invalid
2288 memory as the nickname after the nickname is freed. Affected
2289 file silcd/packet_receive.c.
2291 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2292 saved into wrong slots because the previous number of entries
2293 was not taken into account. Affected file silcd/idlist.c.
2294 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2296 * If we are router and we receive JOIN notify to a channel that
2297 does not have any users then notified client is marked as the
2298 channel founder, as it is it. The affected file is
2299 silcd/packet_receive.c
2301 * Added to the extended hash table API's table_del_*ext functions
2302 the destructor as argument too, so that the caller can decide
2303 which destructor to use or whether to use destructor at all.
2304 Affected file lib/silcutil/silchashtable.[ch].
2306 * Fixed ID Cache purging. It actually deleted the entries from
2307 the hash table after the data was freed. The hash table ended
2308 up comparing freed memory. The affected file is
2309 lib/silccore/silcidcache.c.
2311 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2313 * Fixed Irssi SILC client's KILL command's HELP syntax.
2315 * The USERS command now resolves the detailed user information
2316 if the userinfo field is missing. Affected file is
2317 lib/silcclient/command_reply.c.
2319 * Do not print error in silc_file_read if the read file does
2320 not exist. Just silently return NULL. Affected file is
2321 lib/silcutil/silcutil.c.
2323 * Fixed the silc_log_output to not wine about NULL filename
2324 and to not create some bogus " " filename. Affected file is
2325 lib/silcutil/silclog.c.
2327 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2329 * Fixed various printing bugs on the user interface in the
2330 Irssi SILC Client. Minor changes that were forgotten from
2333 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2335 * Fixed the configure.in.pre and the compilation and distribution
2336 environment to support the new autoconf 2.52. That version is
2337 now required to compile the CVS trunk.
2339 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2341 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2342 to generally parse user@fqdn format strings. Affected file
2343 lib/silcutil/silcutil.c.
2345 * Added nickname_format and nickname_force_format fields to the
2346 SilcClientParams structure. The first one defines the format
2347 for the nicknames that the library will enforce if the receives
2348 multiple same nicknames. The second one is boolean value and
2349 can be used to force the library to always enforce the format
2350 to the nicknames regardles whether there are multiple nicknames
2351 or not. This configurable formatting was employed to flexibly
2352 support accessing multiple nicknames from the user interface.
2353 The userinterface can now set the nicknames to what ever format
2354 they prefer. Affected file lib/silcclient/silcapi.h.
2356 Added function silc_client_nickname_format to the file
2357 lib/silcclient/idlist.c. It performs the nickname formatting.
2359 Added new field `hostname´ to the SilcClientEntry context.
2360 It holds the hostname of the client. Affected file is
2361 lib/silcclient/idlist.h.
2363 * Irssi SILC Client sets the nicknames in nick@hostn format.
2364 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2365 irssi/src/silc/core/silc-core.c.
2367 The WHOIS printing now also shows both the real nickname and
2368 the formatted nickname so that user knows how to access the
2369 user if there are multiple same nicknames cached. Affected
2370 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2371 printing formatting too to take the hostname now as a separate
2372 argument. The Affected file is
2373 irssi/src/fe-common/silc/modules-formats.[ch].
2375 * Changed the silc_client_get_clients_local to accept the formatted
2376 nickname as argument. It accepts the real nickname too but the
2377 formatted nickname can be used to find the true entry from
2378 multiple entries. Affected file lib/silcclient/silcapi.h and
2379 lib/silcclient/idlist.c.
2381 * Added nickname_format_parse field to the SilcClientParams.
2382 It is a callback function provided by the application to parse
2383 the nickname out of the formatted nickname string. The library
2384 calls it to get the nickname from the formatted string. Since
2385 the application generally knows better the format of the nickname
2386 string it parses it instead of the library, even though library
2387 encodes the formatted string. If the callback function is not
2388 provided then the library will use the string as is. The
2389 affected file is lib/silcclient/silcapi.h.
2391 * All the nickname strings passed to the client library in
2392 commands are now expected to be formatted nickname strings.
2393 If the command does not support the formatted nickname string
2394 it will assume that the sent string is the actual nickname.
2395 Affected file lib/silcclient/command.c.
2397 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Added public key authentication support to OPER and SILCOPER
2400 commands in the client library. Affected file is
2401 lib/silcclient/command.c.
2403 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Changed the get_auth_methdod client operation to be asynchronous.
2406 It can be async if the application resolves the authentication
2407 method from the server during the negotiation. Added new
2408 SilcGetAuthMeth completion callback that the application will
2409 call after resolving the authentication method.
2411 Added function silc_client_request_authentication_method that
2412 the application can use to resolve the authentication method
2413 from the server. Added also SilcConnectionAuthRequest callback
2414 that the library will call after the server has replied. The
2415 application can call this function if it does not know the
2416 current authentication method.
2418 Affected files are lib/silcclient/client.c and
2419 lib/silcclient/silcapi.h.
2421 * The Irssi SILC client now automatically resolves the authentication
2422 method incase any configuration information is not present (and
2423 currently there never is). The affected file is
2424 irssi/src/silc/core/client_ops.c.
2426 * Fixed public key authentication from the client library.
2427 Affected file lib/silcclient/protocol.c. Changed also the
2428 protocol specification about the public key authentication in
2429 the connection authentication protocol. The actual data to be
2430 signed is now computed with a hash function before signing.
2432 * Fixed the public key authentication from the server as well.
2433 Affected file silcd/protocol.c.
2435 * Removed the mlock()'s from the memory allocation routines.
2436 Affected file lib/silcutil/silcmemory.c. The ./configure does
2437 not check anymore for the mlock(). Affected file is
2440 * Fixed USERS command in server to allow the execution of the
2441 command for private and secret channels if the client sending
2442 the command is on the channel. Affected file silcd/command.c.
2444 * Fixed silc_client_get_clients_local to return the clients
2445 count correctly. It could return wrong value. Affected file
2446 lib/silcclient/idlist.c.
2448 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2450 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2451 types. The assembler optimizations seemed not to like 64-bit
2452 data types. The assmebler optimizations thus are now enabled
2453 also for BSD systems as opposed to only enable them for Linux.
2455 * Do not check for threads at all on BSD systems. Affected
2456 file configure.in.pre.
2458 * Removed -n and -h options from the Irssi SILC Client since
2459 they are not used in silc.
2461 * Fixed the prime generation to assure that the first digit
2462 of the generated random number is not zero since our conversion
2463 routines does not like number strings that starts with zero
2464 digit. If zero digit is seen the random number is regenerated.
2465 This caused some corrupted RSA keys when the zero first digit
2466 was met. Affected file lib/silcmath/silcprimegen.c.
2468 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Fixed WIN32 configuration in the ./configure script.
2471 Fixed to include xti.h on environments that has it.
2472 Patches by Carsten Ilchmann and andrew.
2474 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Changed the silc_id_create_client_id to be collision
2477 resistant. It is now assured that there cannot be created
2478 two same client ID's. I suspect that some weird bugs in
2479 the server were actually caused by duplicate Client IDs.
2480 Affected file silcd/serverid.[ch]. A router receiving
2481 new ID now also assures and informs the sending server
2482 if the ID caused collision.
2484 * Changed the silc_id_create_channel_id to also assure that
2485 there are no collisions.
2487 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * Statement about ignoring the Mutual Authentication flag when
2490 performing rekey with PFS was a bit misleading. It is ignored
2491 if it was set in the initial negotiation, it cannot be even
2492 set in the rekey. Fixed in the ke-auth draft. Started the
2493 new versions of the protocol drafts in the doc/.
2495 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Fixed a bug in silc_client_command_identify_save when saving
2498 new channel information. The channel name was no duplicated
2499 and caused crash on exit. Affected file is
2500 lib/silcclient/command_reply.c.
2502 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * Fixed the getkey command handling in the server. Send just
2505 empty OK reply to the sender if the key could not be fetched
2506 (but everything else was ok, like the key just was not available).
2507 Changed the public key parameter to optional in the protocol
2508 specs so that empty OK reply can be sent. Affected file
2511 Added a message to Irssi SILC client to tell to user if the
2512 server did not return a public key.
2514 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2516 * Fixed a channel key regeneration bug. It registered new
2517 timeout tasks exponentially until all system resources were
2518 used. Affected file silcd/server.c.
2520 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2522 * Added the SILC Document generator to the scripts/silcdoc.
2523 It can be used to generate the Toolkit Reference Manual out
2524 of the source tree. Internally it will also use the RoboDoc
2525 generator now imported in util/robodoc.
2527 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2529 * Added couple of return's in rekey protocol if error orccurred
2530 during the protocol. The execution must be terminated.
2531 Affected file silcd/protocol.c. Also, terminate the protocol
2532 always with timeout.
2534 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * The client's Client ID was created initally from the wrong
2537 nickname (it could have been in format nick@host) in the
2538 silc_server_new_client. Affected file silcd/packet_receive.c
2540 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2542 * Added some SILC_LOG_ERROR's to various error conditions
2543 if client could not be added to ID cache. Affected files
2544 silcd/packet_receive.c and silcd/server.c.
2546 * When client's sock->user_data is freed, NULL also the
2547 client->router and client->connection pointers. Added check
2548 for these pointers being NULL to various places around the
2549 code. Affected file silcd/server.c.
2551 * Added client->data.registered == TRUE checks to various
2552 places around the code to assure that unregistered client's
2553 are not handled when it is not allowed. Affected file
2556 * Added `bool registered' fields to all
2557 silc_idlist_[server|client]_get_* routines to indicate whether
2558 the fetched client needs to be registered or not. Affected
2559 file silcd/idlist.[ch].
2561 * Add your own entry as registered to the ID cache in the
2562 server. Affected file server.c.
2564 * Fixed a bug in silc_server_new_server. The SilcServer was
2565 set as the new server's context instead of SilcServerEntry.
2566 This naturally caused some weird bugs.
2568 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Do not delete the channel rekey task when adding it
2571 for in silc_server_create_channel_key.
2573 * Changed the silc_server_create_channel_key to return
2574 TRUE or FALSE to indicate the success of the channel key
2577 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2579 * Fixed MSVC++ project files and added missing files to
2580 Makefiles under win32/.
2582 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2584 * Do not add TCP_NODELAY flag if the operating system
2585 does not have it defined. Affected files are
2586 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2588 * Fixed buffer overflow from Irssi SILC Client. Affected
2589 file irssi/src/fe-common/core/themes.c.
2591 * Fixed double free in client library in the file
2592 lib/silcclient/client.c when disconnecting from server.
2594 * Applied double free patch from cras to Irssi SILC client.
2595 Affected files irssi/src/core/[modules/expandos].c
2597 * Fixed the disconnection handling to Irssi SILC Client.
2598 The application must call silc_client_close_connection
2599 in ops->connect client operation in case of failure of
2600 the connection. Affected file is
2601 irssi/src/silc/core/client_ops.c.
2603 * Do not set sock->protocol to NULL in the function
2604 silc_client_close_connection after executing the protocol's
2605 final callback since the sock might not be valid anymore.
2606 Affected file lib/silcclient/client.c.
2608 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2610 * Do not enable SILC_THREADS if the linking with libpthread
2611 did not happen. Affected file configure.in.pre.
2613 * Added notion to protocol specification that server must
2614 verify the sent authentication payload with CMODE when
2615 setting the channel founder key. Implemented it to the
2616 server. Affected file silcd/command.c.
2618 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2620 * Added _EXTRA_DIST SILC distribution variable to the
2621 distributions file. It is used to conditionally add extra
2622 files or directories to the specific distribution. Affected
2623 files ./prepare, Makefile.am.pre and distributions.
2625 Removed the `_' from the start of the distribution names.
2628 * Added README.WIN32 for instructions to compile the Toolkit
2631 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2633 * Fixed a double free in disconnection in the server. Affected
2634 file is silcd/server.c.
2636 * Fixed the lib/silcske/groups.c to work now also with GMP
2637 MP library. The string conversion did not work when using
2638 specific base and the base is indicated in the string as well.
2640 * Created win32/ directory which now includes MSVC++ specific
2641 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2642 It will appear only in the toolkit distribution
2644 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2646 * Changed the key material distribution function in case when
2647 the hash output is too short. The data is now concatenated
2648 a bit differently than it used to. Made the change to the
2649 SKE protocol specification.
2651 * Added better GMP detection to configure.in.pre. A patch
2654 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * Fixed a minor bug in SKE that might cause some problem on
2657 some platforms. Affected file lib/silcske/silcske.c.
2659 * Added the cookie checking for initiator in the SKE. It checks
2660 that the responder returns the sent cookie unmodified. The
2661 affected file is lib/silcske/silcske.c. Added new SKE
2662 error type INVALID_COOKIE that can be sent during the
2663 negotiation. Fixed some memory leaks as well.
2665 * Added the "invalid cookie" error message to Irssi SILC client's
2668 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2670 * Added `task_max' field to the SilcClientParams to indicate
2671 the maximum tasks the scheduler can handle. If set to zero,
2672 default values are used. Affected file lib/silcclient/silcapi.h.
2674 * Fixed memory leaks in silc_client_close_connection. Affected
2675 file lib/silcclient/client.c.
2677 * Added silc_client_del_client_entry to client library to free
2678 all memory of given client entry. Affected file is
2679 lib/silcclient/idlist.[ch].
2681 * Added new functions silc_client_del_channel and
2682 silc_client_del_server to delete channel and server entries.
2683 Affected file lib/silcclient/[silcapi.h/idlist.c].
2685 * Removed silc_client_del_client_by_id from silcapi.h.
2687 * Fixed the INFO command to return the server's own info
2688 correctly when querying by Server ID. Affected file is
2691 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2693 * Removed the non-blocking settings in WIN32 code in the
2694 silc_sock_[read/write] and added SleepEx instead. Affected
2695 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2696 of input data is now checked with FIONREAD and ioctlsocket.
2698 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Call silc_schedule_task_del_by_context in the
2701 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2702 Affected file lib/silccore/silcprotocol.c.
2704 * Call silc_protocol_cancel for active protocols in the
2705 silc_server_close_connection if the funtion
2706 silc_server_free_sock_user_data has not been called.
2707 Affected file silcd/server.c.
2709 * Generic tasks cannot be deleted using the del_by_fd
2710 task deleting function since generic tasks does not match
2711 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2713 * Added a notion to SILCOPER help file that the SILCOPER works
2714 only on router server, not on normal server.
2716 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2718 * Added for WIN32 support for the new scheduler as well.
2719 Affected file lib/silcutil/win32/silcwin32schedule.c.
2721 * Fixed the SHA1 implementation to work on various platforms.
2723 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2726 API. It is part of the scheduler now. Everything else is
2727 as previously but some functions has changed their names.
2728 Checkout the lib/silcutil/silcschedule.h for the interface.
2729 Updated all applications to use the new interface. Affected
2730 files are lib/silcutil/silcschedule.[ch].
2732 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2734 * Found a bug in the SKE implementation. The HASH value,
2735 specified by the protocol, was not computed correctly. The
2736 public key of the responder was not added to the computation
2737 even though it is mandatory. Affected file lib/silcske/silcske.c.
2738 This unfortunately causes incompatibilities with older
2739 clients and servers.
2741 * Added WIN32 specific network init and uninit functions:
2742 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2743 the Winsock2. Affected file lib/silcutil/silcnet.h and
2744 lib/silcutil/win32/silcwin32net.c.
2746 * Set the socket always to nonblocking mode on WIN32 after
2747 reading data or writing data. Affected file is
2748 lib/silcutil/win32/silcwin32sockconn.c.
2750 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2752 * Fixed various compilation problems under WIN32. Affected
2753 files lib/silcutil/win32/silcwin32thread.c and
2754 lib/silcutil/win32/silcwin32schedule.c.
2756 * Removed all _internal.h #includes from public header
2757 files. Internal headers must never be included from
2760 Removed also the lib/silcske/payload_internal.h file.
2762 * All include files that may be needed (public and some others
2763 included by the public headers) by application developers are
2764 now copied to the ./includes directory. It does not copy any
2765 internal headers. Affected file Makefile.defines.pre and all
2766 Makefile.am's under lib/ and subdirs.
2768 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Do not change the ~/.silc directory's permissions automatically.
2771 Affected file irssi/src/silc/core/clientutil.c.
2773 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2775 * Do not cancel the protocol in silc_server_close_connection
2776 it might cause recursion. Now cancelled in the function
2777 silc_server_free_sock_user_data. Affected file silcd/server.c.
2779 * Fixed the silc_server_remove_clients_by_server to regenerate
2780 the channel keys correctly finally. Added also new function
2781 silc_server_remove_clients_channels to actually do it.
2782 Affected file silcd/server.c.
2784 * Fixed the silc_server_new_channel to not crash by giving
2785 wrong router to the new channel. Affected file is
2786 silcd/packet_receive.c.
2788 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2790 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2791 which is given as argument to the silc_client_alloc now.
2792 It can be used to configure the client and set various parameters
2793 that affect the function of the client.
2795 * The USERS command in server did not check whether the channel
2796 is private or secret. Affected file silcd/command.c.
2798 * Added new argument to the USERS command in protocol specification.
2799 The USERS command now can take the channel name as argument
2800 as well. Added support for this in client and server and
2801 updated the protocol specs.
2803 * Completed the GETKEY command in client. It can be now used
2804 to fetch also servers public key not only some clients.
2805 Affected files lib/silcclient/command[_reply].c.
2807 * Added silc_client_get_server to return server entry by the
2808 server name. Affected files lib/silcclient/silcapi.h and
2811 * Redefined the IDENTIFY command in protocol specification to be
2812 more generic. It now can be used to query information about
2813 any entity in the SILC Network, including clients, servers and
2814 channels. The query may be based either the entity's name
2815 or the ID. Added support for this in both client and server.
2817 Affected files silcd/command.c and lib/silcclient/command.c
2818 and command_reply.c.
2820 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2821 the _from_client and _from_server functions. Affected file
2824 * Added silc_client_get_channel_by_id_resolve to the file
2825 lib/silcclient/silcapi.h to resolve channel information by
2826 its ID. Added also silc_client_get_channel_by_id that
2827 does not resolve it from the server.
2829 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2831 * Added SilcServerEntry context into the client library
2832 to represent one server. The INFO command now allocates
2833 these to save the resolved server info. For now on the
2834 client library will also keep information about servers,
2835 connected and resolved with INFO.
2837 The INFO command now allocates the SilcServerEntry context
2838 and saves the server info there. The COMMAND_REPLY in
2839 the INFO now returns the parameters to application in
2840 same order as defined in the protocol specification.
2842 The entries are cached in the client->server_cache.
2844 * The INFO command is now issued after received the Client ID
2845 from the server. Affected file lib/silcclient/client.c.
2847 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2848 to the application as the mode changer might be server.
2849 It is guaranteed that NULL is not returned anymore to the
2850 application. Affected file lib/silcclient/client_notify.c.
2852 The ID Type is now also passed to the application so that
2853 it can check whether the returned entry is SilcClientEntry
2856 Added new function silc_client_get_server_by_id to return
2857 the server entry by ID. Affected files are the
2858 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2860 * Do not create the channel in the Irssi SILC Client when issuing
2861 the JOIN command but when received the sucessful JOIN command
2862 reply. Otherwise the channel might get created even though we
2863 could not join it. The Affected file is
2864 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2866 * Fixed a channel joining bug in router. The router must also
2867 check the channel modes, invite and ban lists etc. when serving
2868 the JOIN command sent by normal server. Affected file is
2869 silcd/command.c. The router now resolves the client's
2870 information from the server who sent the JOIN command if it
2871 does not know it, and processes the JOIN command only after
2874 * Changed the SilcCommandCb to take new argument; void *context2.
2875 Affected file lib/silccore/silccommand.h
2877 The second argument in the command callbacks in the server now
2878 includes the SilcServerCommandReplyContext if the command was
2879 called as pending command callback from the command reply.
2880 Otherwise it is NULL. When called as pending the status of the
2881 command reply will be checked and if it was erronous the
2882 error will be sent to the original sender of the command.
2883 This way the client always receives the error messages even
2884 though the server was actually the one who received the error
2885 when it resent the command to router, for example. Affected
2886 files silcd/command[_reply].[ch].
2888 * Fixed sending WHOWAS command's error message to client if
2889 the requested client could not be found. It was missing.
2892 * Changed the CMODE and CUMODE commands reply arguments in the
2893 protocol specification. The Channel ID is now sent in both
2894 of the commands to identify the channel. Implemented this
2895 new feature to the client and server. Affected files
2896 lib/silcclient/command_reply.c and silcd/command.c.
2898 * Made better checks for invite and ban lists in the JOIN
2899 command in server. Affected file silcd/command.c.
2901 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * The server now performs the incoming host IP/DNS lookup
2904 using the silc_socket_host_lookup and thus does not block
2905 the server anymore. Affected file silcd/server.c.
2907 * Completed the multi-thread support for SILC Scheduler in
2908 the lib/silcutil/silcschedule.c.
2910 * Fixed the configure.in.pre to detect the pthread correctly
2913 * Fixed a deadlock in silc_task_queue_wakeup in the file
2914 lib/silcutil/silctask.c.
2916 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2918 * Added new function silc_schedule_wakeup that is used in
2919 multi-threaded environment to wakeup the main thread's
2920 schduler. It needs to be used when a thread adds a new task
2921 or removes a task from task queues. After waking up, the
2922 scheduler will detect the task queue changes. If threads
2923 support is not compiled in this function has no effect.
2924 Implemented the wakeup mechanism to both Unix and WIN32
2925 systems. Affected files are lib/silcutil/silcschedule.[ch],
2926 lib/silcutil/unix/silcunixschedule.c and the
2927 lib/silcutil/win32/silcwin32schedule.c.
2929 * Added new function silc_task_queue_wakeup to wakeup the
2930 scheduler by the specified task queue. Affected file
2931 lib/silcutil/silctask.[ch].
2933 * The silc_socket_host_lookup_start now wakes up the scheduler
2934 after adding the timeout task. Affected file is
2935 lib/silcutil/silcsockconn.c.
2937 * The silc_socket_host_lookup is synchronous now if the threads
2938 support is not compiled in. However, the callback is still
2939 called asyncronously through the scheduler, anyway. Affected
2940 file lib/silcutil/silcsockconn.c.
2942 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2944 * Added new function silc_socket_host_lookup to perform
2945 asynchronous IP and FQDN lookups for the socket connection.
2946 Affected files lib/silcutil/silcsockconn.[ch].
2948 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2951 that may or may not compile the mutex support in.
2953 Changed the silc_mutex_alloc interface. It allocates the
2954 mutex now to the sent pointer and returns TRUE or FALSE.
2956 Affected file lib/silcutil/silcmutex.h.
2958 * Wrote the SILC Task Queue interface to support multi-threads.
2959 Affected file lib/silcutil/silctask.[ch].
2961 * Wrote the SILC Scheduler to support multi-threads. Affected
2962 file lib/silcutil/silcschedule.c.
2964 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2967 in lib/silcutil/win32/.
2969 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Defined SILC Mutex API and SILC Thread API and implemented
2972 them for Unix. Affected files are
2973 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2974 lib/silcutil/unix/silcunixmutex.c and
2975 lib/silcutil/unix/silcunixthread.c.
2977 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2979 * Fixed the silc_server_remove_clients_by_server's channel
2980 key re-generation. The hash table handling was incorrect
2981 and would not work with many channels. Affected file is
2984 * Fixed some memory leaks around the server code.
2986 * Rewrote the silc_server_get_users_on_channel to support IPv6
2987 based Client ID's. Affected file silcd/server.c.
2989 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2990 specification. However, a separate document must be written
2991 to define the detailed signing procedure and the payload
2992 associated with the flag. Defined the flag to the
2993 lib/silccore/silcchannel.h as well.
2995 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2997 * Changed the dynamic tables to static size tables in the
2998 lib/silccrypt/silchmac.c.
3000 * Removed GCC dependencies from the code. A patch by cras.
3002 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * Do not show the error "Error receiving packet bla bla"
3005 in server if it really was not an error (-2 means that reading
3006 is pending). Affected file silcd/server.c.
3008 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3010 * Fixed a possible crash in silc_server_remove_clients_by_server
3011 in silcd/server.c. Fixed there also some memory leaks.
3013 * Fixed the silc_idlist_replace_client_id. It could replace
3014 wrong key in the hash table. Affected file silcd/idlist.c.
3016 * Do not check whether there are global users on the channel
3017 if the channel->global_users is FALSE. Affected functions
3018 silc_server_remove_from_one_channel and
3019 silc_server_remove_from_channels in silcd/server.c. Also,
3020 do not check if the removed client is local as we can be
3021 sure that global client was not removed from the channel
3022 and checking for global users is not needed.
3024 * The silc_server_remove_clients_by_server now re-generates
3025 the channel keys correctly for those channels that had
3026 clients removed from them. Affected file silcd/server.c.
3028 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3030 * Found the reason of random crashes in the server. We weren't
3031 ignoring the SIGPIPE signal (which can be sent in write())
3032 and it crashed the server. Affected file silcd/silcd.c.
3034 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * Assure that sock->user_data is not NULL in the function
3037 silc_server_packet_send in silcd/packet_send.c.
3039 * Disconnect the remote connection if it could not be added
3040 to any ID lists in the server. The affected file is
3043 * Check in silc_server_packet_send[_real/dest] that the
3044 socket is not disconnecting and ignore the data if it is.
3045 Affected file silcd/packet_send.c.
3047 * Define inline to __inline on native WIN32 compilation.
3048 Affected file includes/silcwin32.h.
3050 * Added some explicit type casts for inline code since MSVC
3051 require them. Affected files lib/silcutil/silcbuffer.h,
3052 lib/trq/silcdlist.h and lib/trq/silclist.h.
3054 * Print warning in log files from now on if the packet
3055 decryption fails. Affected file silcd/server.c.
3057 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3059 * Changed the `say' client operation's interface to accept
3060 new `type' argument to indicate the type of the message sent
3061 by the library. The application may filter the library's
3062 messages according the type. The affected file is the
3063 lib/silcclient/silcapi.h.
3065 * Added two new functions to lib/silcclient/silcapi.h:
3066 silc_client_del_client and silc_client_del_client_by_id.
3067 Affected file lib/silcclient/idlist.c.
3069 * Moved the clientincludes.h from includes/ to silc/ and
3070 serverincludes.h from includes/ to silcd/.
3072 * The modes for the CMODE and CUMODE are now passed as
3073 uint32 for application with COMMAND_REPLY. The affected
3074 file is lib/silcclient/command_reply.c.
3076 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3078 * /WHOIS without arguments shows client's own information.
3079 Affected file lib/silcclient/command.c.
3081 * Changed PING to not accept any arguments. The specs
3082 says that client can ping only the connected server so
3083 requiring an argument is not needed. Affected file is
3084 lib/silcclient/command.c.
3086 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Fixed a fatal bug in private message sending and reception
3089 encryption and decryption when using private message keys.
3090 The implementation was incorrect and did not follow the
3091 specification. It causd that some of the message were
3092 lost since it did not use the sending and receiving keys
3093 as the protocol suggests. This has been fixed and will cause
3094 incompatibilities with older clients when sending private
3095 message encrypted with private message keys. Affected files
3096 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3097 and various other in Irssi SILC Client.
3099 Added `responder' boolean argument to the functions
3100 silc_client_add_private_message_key[_ske] to indicate when
3101 the key is added as responder or initiator of the key
3104 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3106 * Removed the silc_ske_check_version function and created
3107 a SilcSKECheckVersion callback. Added also a function
3108 silc_ske_set_callbacks that is now used to set all SKE
3109 callbacks. The callback functions are not given to
3110 the SKE functions anymore, but this function is used to
3113 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3115 * Added `silc_version' argument to the silc_client_alloc
3116 to define the version of the application for the library.
3117 The library will use the version string to compare it
3118 against the remote host's (usually a server) version
3119 string. Affected file lib/silcclient/silcapi.h
3121 * Added the KE protocol context to Key Agreement context
3122 in client library so that we can abort the SKE if it
3123 is in process when we get timeout. Affected file is
3124 lib/silcclient/client_keyagr.c.
3126 * Do not resolve the client ID forever if it returns in the
3127 first time that such client does not exist. This was done
3128 for example with private message. Affected file is
3129 lib/silcclient/client_prvmsg.c.
3131 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Do not add regex.h for WIN32. The affected file
3134 includes/silcincludes.h.
3136 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3137 not work yet 100%. It generates the DLL's automatically
3138 when compiling with --with-win32 under cygwin.
3140 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3142 * lib/contrib/regex.c is not compiled on WIN32.
3144 * Added silc_net_get_socket_opt function to the
3145 lib/silcutil/silcnet.h.
3147 * Added includes/silcwin32.h for WIN32 specific includes
3150 * Do not use ptime structure or any of the posix process
3151 functions on WIN32 in lib/silccrypt/silrng.c.
3153 * Added silc_gettimeofday to provide generic function
3154 for struct timeval on all platforms. Added the function
3155 to lib/silcutil/silcutil.h.
3157 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3159 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3160 library as they clearly belong there. As a plus side we
3161 can make the actual socket connection routines platform
3164 Added also new generic function silc_socket_read and
3165 silc_socket_write (that used to be silc_packet_[read/write].
3166 The implementation of these are platform specific.
3168 * Added WIN32 specific routines of silc_socket_[read/write]
3169 to lib/silcutil/win32/silcwin32sockconn.c.
3171 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3173 * Added preliminary support for native WIN32 compilation under
3174 cygwin (using the -mno-cygwin option for GCC) to the
3175 ./configure.in.pre. The --with-win32 now prepares the
3176 compilation for native WIN32.
3178 * Rewrote the SILC Scheduler interface in the file
3179 lib/silcutil/silcschedule.h. The scheduler is now context
3180 based and does not have anymore any global static scheduler.
3181 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3182 and created lib/silcutil/win32 directory for WIN32 based
3185 * Added Unix specific network routines to the
3186 lib/silcutil/unix/silcunixnet.c and the old
3187 lib/silcutil/silcnet.c includes now only generic routines.
3189 Added WIN32 specific network routines to the
3190 lib/silcutil/win32/silcwin32net.c.
3192 * Added Unix specific utility functions from the
3193 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3195 * Added WIN32 SILC Scheduler to the file
3196 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3199 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3201 * Do not handle JOIN notify in the server if the target client
3202 is not registered (idata->registered == FALSE). The affected
3203 file is silcd/packet_receive.c.
3205 * Update the nickrec->founder in event_cumode in the Irssi SILC
3206 client. Affected file irssi/src/silc/core/silc-channels.c.
3208 * Fixed the CUMODE_CHANGE notify handling in the server when
3209 server and router are announcing their clients on channels.
3210 Now the mode changes are saved and notified correctly. The
3211 affected file is /silcd/packet_receive.c.
3213 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3214 They really did not replace the cache entry in the ID Cache.
3215 Now they do that. Affected file silcd/idlist.c.
3217 * Fixed the KICK notify handling in the Irssi SILC client to
3218 update the channel records so that the kicked client does not
3219 appear to be on the channel. The affected file is
3220 irssi/src/silc/core/silc-channels.c.
3222 * Always update the conn->current_channel when executing command
3223 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3225 * Fixed the KILL notify handling in Irssi SILC client to remove
3226 the killed client on all channels.
3228 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3230 * Fixed the silc_parse_command_line to remove extra spaces
3231 from the start and end of the arguments. Affected file is
3232 lib/silcutil/silcutil.c.
3234 * Cancel and free any active protocol in the function
3235 silc_server_close_connection. Affected file silcd/server.c.
3237 * Cancel and free any active protocol in the function
3238 silc_client_close_connction. Affected file is
3239 lib/silcclient/client.c.
3241 * Do not execute the KILL command for clients that are in
3242 history (ie. they are not in the network). Affected file is
3245 * Fixed KILL notify handling, client does not crash anymore.
3246 Affected file irssi/src/silc/core/silc-channels.c.
3248 * Reduced the default packet buffer size from 2048 to 1024 in
3249 lib/silccore/silcpacket.c.
3251 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3252 counter to the SKE context that is incresed when the SKE library
3253 performs async operation outside the library. If the outside
3254 process frees the SKE context and FREED status will be set
3255 and the library will detect after the sync operation that the
3256 libary is freed. The affected files are
3257 lib/silcske/silcske[_status].[ch].
3259 * Resolve the client entry information in the function
3260 silc_client_channel_message to assure that NULL pointer is not
3261 passed as client entry to the application. */
3263 * Fixed the task timeout calculation to assure that there is
3264 never negative timeouts. The affected file is
3265 lib/silcutil/silcschedule.c.
3267 * Fixed the channel user mode notification sending in server.
3268 It was sent point-to-point to the router (or to server by router)
3269 but it needs to be destined to a channel. The routines now
3270 supports sending the channel user mode notifys to the channels
3271 when announcing clients and channels. Affected files are
3272 silcd/server.c and silcd/packet_receive.c.
3274 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3275 It did not actually replace the old channel entry in the cache.
3276 Affected file lib/silcclient/client_notify.c.
3278 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Fixed a possible crash in silc_packet_send_prepare. It now
3281 assures always that there is enough space in the buffer and
3282 at the tail area of the buffer (for MAC).
3284 Fixed the inbound buffer reallocation in silc_packet_read.
3285 It was old code and did not handle the reallocation correctly.
3288 The affected file is lib/silccore/silcpacket.c.
3290 * Fixed buffer overflow in silc_parse_nickname in the file
3291 lib/silcutil/silcutil.c.
3293 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3295 * make install generates new server keys only if there is not
3298 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3300 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3301 Added check that if the NOREPLY is set then we will not send
3302 the away message. This avoids infinite loop of away messages
3303 if both clients are away. The affected file is
3304 lib/silcclient/client_prvmsg.c.
3306 * Fixed client crash if /NICK was given without arguments.
3307 Affected file lib/silcclient/command.c.
3309 * Server does not send the invite list in INVITE command back
3310 to the client if the list was not altered. Added this notion
3311 to the protocol spec as well. Affected file silcd/command.c.
3313 Fixed possible crash in INVITE command by checking the
3314 value of silc_server_get_client_route command.
3316 * Fixed the INVITE notify type handling. The arguments are now
3317 taken in correct order and client does not crash. The affected
3318 file is irssi/src/silc/core/silc-channels.c.
3320 Removed the "Inviting xxx to channel" message from the
3321 client library away and let the application handle it.
3322 Affected file lib/silcclient/command.c. Added that message
3323 to Irssi SILC client's message formats.
3325 * Fixed CMODE command crash in client. It now checks the
3326 amount of arguments correctly and does not crash. The affected
3327 file is lib/silcclient/command.c.
3329 * Do not create new channel automatically in silc_channels_join
3330 but check whether the channel by that name already exists.
3331 Affected file irssi/silc/core/silc-channels.c.
3333 * Do not send the SERVER_SIGNOFF to router if the disconnected
3334 entity was the router. Affected file silcd/server.c.
3336 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3337 SILC client as it was missing from there.
3339 Added the handling of the KICK notify to the Irssi SILC client
3340 as it was missing. Added "you have been kicked" message to
3341 Irssi SILC client's message modules formats.
3343 Added the handing of the KILL notify to the Irssi SILC client
3344 as it was missing. Added the kill message module formats
3347 The affected file is irssi/src/silc/core/silc-channels.c.
3349 * The router did not save the channel mode the server announced.
3350 Affected file silcd/packet_receive.c.
3352 * Fixed a possible crash in INFO command in server. If the
3353 server did not provide the server info it crashed. Affected
3354 file silcd/command.c.
3356 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * Fixed the GETKEY command in the server to check also the
3359 global list. Otherwise the GETKEY would not work correctly
3360 in normal SILC server. Affected file silcd/command.c.
3362 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Fixed GETKEY crash, it crashed if the command did not succseed.
3366 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3368 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3369 is now real and not just an macro interface to GMP.
3371 Removed the entire GMP from the source tree and imported new
3372 NSS MPI library instead. Reason for removing GMP is that it is
3373 extremely large and compiles extremely slow. The NSS MPI
3374 is only a few files and compiles in less than 10 seconds.
3375 The speed is also about the same as GMP. The MPI is imported
3376 to lib/silcmath/mpi.
3378 If the system has GMP installed we will still use the GMP.
3379 If it is not then the NSS MPI will be compiled.
3381 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Merged a long nickname (127 characters long) crash bugfix from
3384 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3386 * Merged a freed memory reference bugfix from Irssi CVS tree.
3387 Affected file irssi/src/core/commands.c.
3389 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3391 * Added the server's public key sving and verification to the
3392 server when performing the SKE. This was missing and the
3393 remote server's (or router's) public key was accepted without
3394 checking whether we have it previously or trust it at all.
3395 Affected file silcd/protocol.c.
3397 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Check in the silc_server_timeout_remote if protocol is active
3400 and make sure that the protocol's final callback is called so
3401 that all memory if freed. Affected file silcd/server.c.
3403 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * silc_server_whois_send_reply crashed the server if the nickname
3406 was 127 characters long. Affected file silcd/command.c.
3408 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Added sanity check to the silc_server_new_client. If the hostname
3411 is provided inside username then check that the provided hostname
3412 really is the same as the resolved one. If the hostname was not
3413 resolved then check it from the public key. Affected file is
3414 silcd/packet_receive.c.
3416 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3417 if the server disconnected us and the connection is not valid
3418 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3420 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3421 the library to the lib/silcutil/silcutil.[ch].
3423 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3425 * Close log file after open. Affected file
3426 lib/silcutil/silclog.c.
3428 * Check whether sock == NULL in silc_client_send_packet and return
3429 if it is. Affected file lib/silcclient/silcclient.c.
3431 * Check rec->entry == NULL in the Irssi SILC Client before
3432 sending the channel message. Affecte file is
3433 irssi/src/silc/core/silc-servers.c.
3435 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3437 * Merged a splitted window bugfix from Irssi CVS tree. The
3438 affected file is irssi/src/fe-text/textbuffer-view.c.
3440 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3441 It did not print nickname.
3443 * Improved the distributions system a bit.
3445 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3448 irssi/src/fe-text/gui-window.c.
3450 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3451 to in-active server. The affected file is
3452 irssi/src/silc/core/client_ops.c.
3454 * Resolve the client in USERS command reply if the entry does
3455 not have username resolved. The affected file is
3456 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3457 command to WHOIS command to really resolve stuff. The USERS
3458 is not used any more in any critical section so WHOIS can
3459 be used even though it might be slower than IDENTIFY.
3461 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3464 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3466 * Changed the protocol API a bit more consistent in the
3467 lib/silccore/silcprotocol.[ch].
3469 * Changed the following headers to ROBODoc format:
3471 lib/silccore/silcpayload.h
3472 lib/silccore/silcprotocol.h
3473 lib/silccore/silcsockconn.h
3475 All core library headers are now formatted.
3477 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Fixed a bug in Irssi SILC client; do not show that you are
3480 server/router operator if you really are not. Affected file is
3481 irssi/src/silc/core/client_ops.c.
3483 * Renamed silc_command_free_payload to silc_command_payload_free.
3484 Affected file lib/silccore/silccommand.h
3486 * Added silcmath.h to include the prototoypes of various routines
3487 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3490 * Changed the following headers to ROBODoc format:
3492 lib/silccore/silcchannel.h
3493 lib/silccore/silccommand.h
3494 lib/silccore/silcid.h
3495 lib/silccore/silcidcache.h
3496 lib/silccore/silcmode.h
3497 lib/silccore/silcnotify.h
3498 lib/silccore/silcpacket.h
3499 lib/silcmath/silcmath.h
3501 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Added checking to the server code not to start the server if
3504 ciphers and stuff are not configured properly. Affected files
3505 silcd/serverconfig.[h] and silcd/server.c.
3507 * Changed the layout of the header files of the public interfaces
3508 in the SILC libraries. The new layout supports ROBODoc
3509 documentation tool (and some others) so that it is easy to create
3510 a library reference manual. All the other headers and source
3511 code must still follow the CodingStyle document. Also source
3512 code must not include these ROBODoc stuffs, only the headers.
3513 Furthermore, all public interface headers must now be named
3514 by using `silc' prefix, example: silcapi.h, silccipher.h.
3515 Some files were renamed due to this. All the other headers
3516 must not be used as public interfaces. I will update the
3517 CodingStyle document later. Changed following headers, so far:
3519 lib/silcclient/silcapi.h
3520 lib/silccore/silcauth.h
3521 lib/silccore/silcprivate.h
3522 lib/silccrypt/silcdh.h
3524 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Removed silc_client_packet_send_flush from the client library
3529 as it is not needed. Affected file lib/silcclient/client.[ch].
3531 * Added printing of message of unresolved authentication method
3532 to the Irssi SILC client. Added it to the module formats.
3533 Removed the same message from the client library.
3535 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Added new distribution feature, DISTLABEL. Every distribution
3538 can define own preprocessor label that can be used in the
3539 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3540 file distributions, acconfig.h.pre and prepare.
3542 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3544 * Added Makefile.defines_int to include the actual definitions
3545 for Makefile.defines.in. Tested the new distribution system,
3546 created distributions and tested installation.
3548 * Added AWAY message printing to the Irssi SILC client. Added
3549 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3551 * Added SCONNECT command to call the SILC's CONNECT command.
3552 Cannot use CONNECT directly since Irssi uses that internally.
3553 Affected file irssi/src/silc/core/silc-servers.c.
3555 Added ACTION local command. It is same as ME command but takes
3556 the channel as mandatory argument.
3558 Rewrote some of the Irssi's help files to suite for SILC
3561 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3563 * Added Makefile.defines[.in] that should for now on be included
3564 in all Makefile.am file in the source tree. That file includes
3565 all common compilation definitions for SILC source tree.
3567 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Minor changes to the ./prepare script to change the package
3570 name according the distribution name to the configure.in.
3572 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Created new distribution system. Added file `distributions'
3575 that defines all the distributions that can be created out of
3576 the SILC source tree. The ./prepare script now reads that
3577 file to determine how to prepare the distributions. The
3578 first argument to the ./prepare is the name of the distribution
3579 and second is the version of the distribution. If given
3580 without arguments it creates the default (toolkit) distribution
3581 with the default version (defined in ./prepare).
3583 All Makefile.am files that are subject to the distributions
3584 are now named as Makefile.am.pre. These are ./Makefile.am
3585 and lib/Makefile.am. Others may be changed later.
3587 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3589 * Added invite list, ban list, some key management and connection
3590 error message printing to module formats in the Irssi SILC client.
3592 * Added new silc_client_set_away_message to set the away message
3593 that is back to the person who sent private message. The
3594 affected file lib/silcclient/silcapi.h and the
3595 lib/silcclient/client_prvmsg.c.
3597 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Fixed the private message sending in the Irssi SILC client,
3600 added local command KEY to the Irssi SILC client.
3602 Added key management and key agreement message formats to the
3603 irssi/src/fe-common/silc/module-formats.[ch].
3605 Added USERS (alias WHO) printing, server/router operator
3606 indication and LIST command printing to the module formats.
3608 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Fixed channel joining notify handling, cumode notify handling
3611 from Irssi SILC client.
3613 * Added SILC specific module-formats to the Irssi SILC client so
3614 that SILC specific message hilighting, colors etc is possible.
3615 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3617 Added channel mode, channel user mode, actions, notices,
3618 whois and whowas printing to the the module-formats.c.
3620 * Fixed a bug in channel deletion in the server. The channel
3621 is not left to the cache even if the channel founder auth mode
3622 is set when there are no users anymore on the channel. Affected
3623 file silcd/server.c.
3625 * The silc_net_localhost now resolves the entire hostname including
3626 the domain name. Affected file lib/silcutil/silcnet.c.
3628 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Changed the ask_passphrase client operation to be ascynchronous.
3631 It has now a completion callback and a context that the
3632 application must call after it has got the passphrase from
3633 the user. Affected files lib/silcclient/silcapi.h,
3634 lib/silcclient/protocol.c, lib/silcclient/command.c and
3637 Added SilcAskPassphrase callback that the application calls
3638 to deliver the passphrase to the library.
3640 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3641 The public key verification and especially a certificate
3642 verification is asynchronous procedure.
3644 Added new SILC_SKE_STATUS_PENDING status to indicate the
3645 request is pending and a callback will be called to finalize
3648 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3649 indicate that remote end did not send its public key (or
3650 certificate), even though we require it. Added check for this
3651 condition in the SKE. This was a security bug, now fixed.
3653 Defined new SilcSKEVerifyCbCompletion callback that is called
3654 when the verification process is completed.
3656 The affected files lib/silcske/silcske_status.h and
3657 lib/silcske/silcske.[ch].
3659 * Changed the verify_public_key client operation to be async
3660 as well. Defined SilcVerifyPublicKey callback that is used to
3661 indicate the success of the public key verification process.
3663 Changed the server and client to use the new async client
3666 * Changed the Irssi SILC client's internal scheduler to be called
3667 twice as many times as it used to be. As a result the client
3668 should be a bit faster now. Affected file is
3669 irssi/src/silc/core/silc-core.c.
3671 * Added support to Irssi SILC client of asynchronous public key
3672 verification and passphrase inquiry. Affected file is
3673 irssi/src/silc/core/silc-core.c.
3675 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Do not say "You have left channel %s" in client library.
3678 Moved it to the application. Affected files are
3679 lib/silcclient/command.c and silc/client_ops.c.
3681 * Fixed silc_client_get_clients. Command context was not
3682 duplicated and was freed memory in the callback. Affected
3683 file lib/silcclient/idlist.c.
3685 * Do not say "you are now talking..." on JOIN command in the
3686 client library. The appliation must handle it.
3688 * Do not say ".. changed topic to" in command reply in the
3689 client libary. The application must handle it.
3691 * Fixed TOPIC command sending in the client library.
3693 * Fixed a memory leak in silc_client_command_free in the file
3694 lib/silcclient/command.c.
3696 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3698 * Imported a modified version of Irssi client to the source tree.
3699 The Irssi will be used to create a new client called
3700 Irssi SILC. Imported to irssi/.
3702 Added silc_core_init_finish function to the Irssi. Affected
3703 file irssi/configure.in.
3705 A lot changes in the Makefile.ams around the irssi tree.
3707 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * Do not rehash if the new size is same as the old size of the
3710 hash table, in the silc_hash_table_rehash*. The affected file
3711 lib/silcutil/silchashtable.c.
3713 * Replaced hash_table_del_by_context calls from the server
3714 (when channel->user_list and client->channels) to the
3715 hash_table_del as it is sufficient and faster.
3717 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Added silc_hash_table_list, silc_hash_table_get and the
3720 SilcHashTableList structure to provide an alternative way to
3721 traverse the hash table. The affected files are
3722 lib/silcutil/silchashtable.[ch].
3724 * Changed the server's idlist routines to use the hash table
3725 routines to optimize the code.
3727 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3729 * Replaced the client entry's `channel' list and channel entry's
3730 `user_list' list to hash tables for optimized lookup. Changed
3731 the code to use the hash table interface around the code.
3732 Affected file lib/silcd/idlist.[ch].
3734 * Added `auto_rehash' boolean argument to the function
3735 silc_hash_table_alloc to indicate whether the hash table should
3736 auto-rehash when it thinks is appropriate time. It will
3737 increase the hash table size if the there is twice as much
3738 entries in the table than the size of the table, and will
3739 decrease the size if there are twice as less entries than
3740 the size of the table.
3742 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3746 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * silc_idcache_purge_by_context deletes the entry now by context
3749 as it is supposed to do. Affected file lib/silccore/idcache.c.
3751 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3752 client is not anymore valid (WHOWAS givens the info) and not
3753 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3755 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Removed the `data' and `data_len' arguments from the ID Cache
3758 interfaces and added `name' argument. ID Cache does not handle
3759 anymore the binary data only a names associated with given ID.
3761 * When hashing a Client ID with silc_hash_id the entire ID is
3762 not hashed anymore, instead only the hash of the Client ID is
3763 hashed. This way we can access the Client ID from the cache
3764 with Client ID but with the hash of the ID (which is a hash of
3765 the nickname) as well without any difference in performance.
3767 Added also silc_idcache_find_by_id_one_ext to do one on one
3768 searching when we have the actual ID. Added also function
3769 silc_hash_client_id_compare. The affected files are
3770 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3772 * When hashing the name associated with a ID it is always done
3773 in lowercase. This way we can access the cache without worrying
3774 about case-sensitivity, even though, for example nicknames are
3777 * Fixed a bug in server with channel message sending. It put
3778 wrong ID type as destination ID. The affected file
3779 silcd/packet_send.c.
3781 * silc_idcache_del_by_context now deletes from all hash tables
3782 by context. Affected file lib/silccore/idcache.c.
3784 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3786 * Changed the client library to use the new ID Cache interface.
3787 Changes around the source tree.
3789 * Added silc_hash_table_rehash_ext to rehash with specific
3790 hash function. Affected file lib/silcutil/silchashtable.[ch].
3792 * Added silc_hash_string_compare to compare two strings in the
3793 hash table. Affected file lib/silcutil/silcutil.[ch].
3795 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Added new function silc_idcache_del_by_context into the
3798 lib/silccore/idcache.[ch].
3800 * Changed the server's ID list routines to use the new ID Cache
3801 interface. Changes around the source tree.
3803 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Added silc_hash_table_del[_by_context]_ext functions in to the
3806 lib/silcutil/silchashtable.[ch].
3808 Removed silc_hash_table_find_all* routines and added new
3809 silc_hash_table_find_foreach to replace them.
3811 Added silc_hash_table_replace_ext function as extended
3812 replacing function. Separated the simple hash table interface
3813 from the extended hash table interface in the file
3814 lib/silcutil/silchashtable.h.
3816 * Fixed minor bugs and changed it to use some of the new
3817 hash table functions in lib/silccore/idcache.c
3819 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Added new function silc_hash_table_find_all to return all keys
3822 in the hash table by the specified key. As the hash table is
3823 collision resistant it also makes it possible to have several
3824 duplicate keys in the hash table. This function may be used to
3825 find all of the keys from the hash.
3827 Added user_context arguments to the SilcHashFunction,
3828 SilcHashCompare and SilcHashDestructor to deliver user specified
3831 Added new fuctions silc_hash_table_find[_all]_ext to do
3832 extended lookup with specified hash and compare functions and
3833 specified user contexts.
3835 Added new function silc_hash_table_add_ext to add the key
3836 with specified hash function and user context.
3838 Added new function silc_hash_table_foreach to traverse all
3839 entrys in the hash table. Added SilcHashForeach callback
3842 Added new function silc_hash_table_del_by_context to delete
3843 the entry only if the context associated with the key matches.
3845 Affected files are lib/silcutil/silchashtable.[ch].
3847 * Removed silc_hash_[server/client/channel]_id and added just
3848 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3849 silc_hash_id_compare to compare two ID's using as the hash table
3850 comparison function. Added also silc_hash_data to hash
3851 binary data and silc_hash_data_compare to compare it.
3853 * Removed silc_idlist_find_client_by_hash as it is not needed
3854 anymore. Affected file silcd/idlist.[ch].
3856 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3857 to use internally the SilcHashTable. The new ID Cache is a lot
3858 faster than the old one. Some of the ID Cache interface was also
3859 rewritten and obsolete and stupid functions were removed.
3861 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3863 * Added entry_count field to the SilcHashTable to keep the number
3864 of the entries in the table. Implemented the function
3865 silc_hash_table_rehash. Added new function
3866 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3868 Fixed a minor bug in silc_hash_table_free.
3870 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3871 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3872 into the lib/silcutil/silcutil.[ch].
3874 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Implemented a collision resistant hash table into the
3877 lib/silcutil/silchashtable[ch]. See the header and the source
3878 for the SilcHashTable API.
3880 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Merged dotconf version 1.0.2 into lib/dotconf.
3884 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3886 * Do not compile anything in lib/silcsim/* if the SIM support
3887 is not enabled. The tree should now compile without problems
3890 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Compiled the SILC under cygwin. Compiled and tested briefly
3893 without problems. More tests needed. The SIMs didn't compile
3896 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3898 * Fixed possible crash in silc_get_username in the
3899 lib/silcutil/silcutil.c.
3901 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Fixed a va_arg in silc/client_ops.c.
3905 * Oops, RC5 routines were named AES and caused some problems
3906 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3908 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Added new SilcIDIP structure into the lib/silccore/id.h and
3911 replaced the old `ip' fields from all SILC ID's to that type.
3912 This is a step towards IPv6 support.
3914 The silc_id_get_len takes now the ID as an extra argument.
3915 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3916 both IPv4 and IPv6 based ID's.
3918 The affected files are lib/silccore/id.[ch] and other files
3919 around the tree using these routines.
3921 * Removed the ID length arguments in server from various
3922 silc_server_send_notify_* routines -> they are not needed
3925 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Fixed memory leak in silc_encode_pem_file in the file
3928 lib/silcutil/silcutil.c.
3930 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Check minor version as well in the SKE. Affected files are
3933 silcd/protocol.c and lib/silcclient/protocol.c.
3935 * Added --identifier option to the server so that an identifier
3936 can be when creating the public key for the server. Affected
3937 file is silcd/silcd.c.
3939 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3940 lib/silccrypt/silcpkcs.c.
3942 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * Register default ciphers and stuff when using -C option with
3945 the server. Affected file sildc/silcd.c.
3947 * Put back the servers public key filename format, it is better
3948 than the new one. For now, the client keys are saved with the
3949 new filename format. The affected file silc/client_ops.c.
3951 * Implemented the Cipher API for the rest of the ciphers that
3952 did not implement it or implemented it the wrong way.
3954 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Register default ciphers and stuff when using the -S option
3957 in the client. Affected file silc/silc.c. Same also when
3958 creating new key pair with -C option.
3960 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3962 * Fixed the silc_verify_public_key client operation function to
3963 save the public keys differently. The fingerprint is now
3964 used as filename and not the hostname. This way also the
3965 client keys are saved uniquely and not with hostnames. The
3966 affected file is silc/client_ops.c.
3968 * Trimmed the silc_hash_fingerprint function to remove extra
3969 whitespaces from the end of the fingerprint. The affected
3970 file is lib/silccrypt/silchash.c.
3974 * Added silc_cipher_register_default function to register all
3975 default ciphers. It can be used when configuration files
3976 does not exist and the application does not want any specific
3977 ciphers in any specific order.
3979 The SilcDList is now used as silc_cipher_list dynamically
3980 allocated cipher list. Removed the static list all together
3981 and now all ciphers must be allocated to the dynamic list.
3982 The silc_cipher_alloc routine was changed to check only the
3985 All silc_cipher_* routines that used to return int returns
3988 The affected files lib/silccrypt/silccrypt.[ch].
3990 * The same thing was done to silc_hash_* as for silc_cipher_*
3991 routines. Affected files lib/silccrypt/silchash.[ch].
3993 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3994 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3995 Added also silc_pkcs_[un]register[_default] functions.
3996 Removed the data_context from the PKCS API.
3998 * Added silc_hmac_register_default function to register default
3999 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4000 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4001 to unregister all hmacs at once.
4003 * Register the default ciphers, hash functions, PKCSs and HMACs
4004 if client's configuration file does not exist. The affected
4007 * The client did not load the hash functions from the SIM
4008 modules at all. Added support for this. Affected file is
4009 silc/clientconfig.c.
4011 * When decoding public key with silc_pkcs_public_key_decode, check
4012 the supported algorithm only if PKCS are registered. Affected
4013 file lib/silccrypt/silcpkcs.c. The same was done with the
4014 silc_pkcs_private_key_decode.
4016 * Fixed the SILC List routines to keep the list always in order.
4017 It used to change the list's order when traversing the list but
4018 not it preserves the order. Affected file lib/trq/silclist.h.
4020 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Added the client library to use the SilcSocketConnection's
4023 reference counter (by silc_socket_dup) to prevent the bug that
4024 the socket object may be freed underneath async operation.
4026 * The name resolv library checking fixes in the configure.in.pre.
4029 * Created new version of the protocol drafts for future
4030 development. The -03 drafts are the ones that will be changed
4031 in the trunk now and the -02 will remain as they are.
4033 * Send list of CUMODE notifys to the router when announcing
4034 the channel users to the router. Affected file silcd/server.c.
4035 If the router receiving channel founder CUMODE for a channel
4036 that already has channel founder it will send CUMODE notify
4037 to the sender to remove the channel founder rights from the
4038 announced client. Affected file silcd/packet_receive.c.
4040 * The CUMODE notify may now use Server ID as well as the entity
4041 who changes the mode. Updated protocool specs.
4043 * Updated INSTALL and README files.
4045 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * New web pages in the http://silc.pspt.fi. The pages was
4052 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Implemented the [DenyConnectin] config section in the server.
4055 Added silc_server_config_denied_conn to check whether incoming
4056 connection is denied. Affected file silcd/serverconfig.[ch].
4058 * Do not check the ports when checking the incoming configuration
4059 data if the port is 0, meaning any. Affected file is
4060 silcd/serverconfig.c.
4062 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4064 * Fixed buffer overflow in silc_string_compare in the file
4065 lib/silcutil/silcutil.c.
4067 * Fixed double free in silc_server_command_leave in the file
4070 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4072 * Fixed the version checking in the server. Affected file is
4075 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Fixed the configuration data fetching when accepting new
4078 connections in the server. Affected file silcd/server.c.
4080 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Added `sender_entry' argument to the function
4083 silc_server_packet_relay_to_channel so that we can check
4084 whether some destination actually belongs to the same route
4085 the sender belongs (ie, we must not resend the packet to the
4086 sender). Affected file silcd/packet_send.[ch].
4088 * Added `servername' field to the SilcClientEntry in the server
4089 to hold the name of the server where client is from. Affected
4090 file is silcd/idlist.h.
4092 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Moved the channel message encrypting in the router betwen
4095 router connections from silc_server_channel_message to the
4096 silc_server_packet_relay_to_channel since we want to check
4097 whether we have anybody channel before encrypting anything.
4098 Affected files silcd/packet_[receive/send].c.
4100 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4102 * Fixed the [AdminConnection] server config section to support
4103 multiple entries. Affected file silcd/serverconfig.c.
4105 * Added support into the server to check the validity of the
4106 incoming connection before executing any KE or authentication
4109 * The connection configuration is now saved to the KE and
4110 connection auth protocol contexts and not fetched anymore in
4111 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4113 * The local hosts listenning address and port is also resolved
4114 now when starting the server. We want to have the socket object
4115 to include the real address and port for the listener. Added
4116 new function silc_net_check_local_by_sock into the files
4117 lib/silcutil/silcnet.[ch].
4119 * Fixed a broadcast bug in server -> do not broadcast if we
4122 * Fixed a routing bug. Do not route broadcast packets ever.
4123 Broadcast packets must be processed always and not routed since
4124 they may be destined to some other host than yourself and thus
4125 would get routed without no good reason. Affected file is
4128 * Added function silc_server_config_is_primary_route to check
4129 whether primary router connection has been configured (a router
4130 configuration that we are initiating). If there is not, we
4131 will assume that there is only two routers in the SILC network
4132 and we will use the incoming router connection as our primary
4133 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4135 * Changed the order of the broadcasting. Broadcast _after_ the
4136 packet has been processed not before. Affected file is
4139 * Fixed a [ClientConnection] parsing bug. The port was never
4140 parsed correctly thus resulting to port 0. Affected file
4141 silcd/serverconfig.c.
4143 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4144 argument and did not set the broadcast packet flag. Affected
4145 file silcd/packet_send.c. Fixed same bug in the function
4146 silc_server_send_notify as well.
4148 * If we receive NEW_ID packet for our own ID in the server, ignore
4151 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Removed the nickname from the Private Message Payload.
4156 Updated the code and the protocol specs.
4158 * Updated protocol specs for submitting to the IETF.
4160 * Tweaked the Random Number Generator a bit. Affected file
4161 lib/silccrypt/silcrng.c. Exported a new function
4162 silc_rng_[global]_add_noise which can be used to add more
4165 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Do not parse packets with different timeout when protocol
4168 is active -> may cause problem with rekey. Affected file
4171 * When server receives signoff notify it must not create
4172 new channel key if the client is on any channels since the
4173 sender of the signoff notify will create it.
4175 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Added printing of error messages during SKE protocol from the
4178 failure packet sent by server during SKE. Affected file
4181 * Removed the client's failure_callback handling with timeout
4182 and handle it immediately when received.
4184 * The SKE library returned wrong type in SUCCESS and FAILURE
4185 packets. They must be 32 bit MSB not 16 bit MSB.
4187 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Ok, rewrote the logic of the re-key and now it seems to work.
4190 I tested it on high traffic with frequent re-keys without
4191 problems. Added hmac_receive (and renamed hmac to hmac_send)
4192 in SilcClientConnection in lib/silcclient/client.h and
4193 in SilcIDListData in silcd/idlist.h. Also, removed the
4194 SilcPacketParserContext's cipher and hmac fields as they are
4195 not needed anymore and actually caused some problems when
4196 the ciphers and hmac's changed underneath the packet parser.
4198 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * If re-key protocol is active then process the incoming packets
4201 synchronously since we must assure that icoming packets encrypted
4202 with the old key is processed before the new keys is set to
4203 use. This is true other packets than for REKEY packets.
4204 Affected file silcd/server.c. The same was done to client library
4205 as well, affected file lib/silcclient/client.c.
4207 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Fixed bug in client and server to accept the force send if
4210 the packet is send from silc_[server/client]_packet_process
4211 function. Otherwise the packets are never delivered, oops.
4213 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Disable force sending of packets when REKEY protocol is active.
4216 We must assure that no packet is sent directly when rekey is
4217 performed. All packets must be sent through packet queue.
4218 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4219 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4220 function is silc_[server/client]_packet_send_real to check
4223 * Replaced the SIM paths from example config files to
4224 /usr/local/modules. Also, make install creates now
4225 /usr/local/silc/logs directory to hold all the SILC server
4228 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Made the configure.in.pre work on Solaris. Patch by salo.
4232 * Made all ciphers compatible with non-x86 machines. Defined
4233 CBC mode macros into lib/silccrypt/ciphers_def.h.
4235 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Fixed the make install.
4239 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * When MAC computation fails the silc_packet_decrypt returned 0
4242 even though it was supposed to return -1. Fixed this. The
4243 affected file is lib/silccore/silcpacket.c.
4245 * Do not replace the config files in /etc/silc (in make install)
4246 if they already exist. Affected file ./Makefile.am.
4248 * Do not send re-key packets immediately but through packet queue.
4249 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4251 * Changed silc_net_check_host_by_sock to return FALSE if the
4252 IP/DNS could not be resolved. Though, it returns the IP address
4253 now even if it could not resolve it (but returns also FALSE).
4254 Affected file lib/silcutil/silcnet.[ch].
4256 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Added silc_pkcs_decode_identifier to decode the public key's
4259 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4260 Added also silc_pkcs_free_identifier. Added also new context
4261 SilcPublicKeyIdentifier.
4263 * Added -S option to the silc client. It is used to dump the
4264 contents of the specified public key file.
4266 * Changed the PKCS api to return the public key length when
4267 setting the public key.
4269 * Fixed a fatal bug in the public and private key file loading.
4270 Affected file lib/silccrypt/silcpkcs.c.
4272 * Execute the packet parsing for client with zero (0) timeout
4273 if the protocol is active. Affected file silcd/server.c.
4275 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4277 * Made the key generation options to the silcd program. Added
4278 -C option, equivalent to client's option.
4280 * Added new [ServerKeys] config section to the server. It
4281 configures the server's public and private key.
4283 * Defined generic Public Key Payload into the protocol
4284 specification to send specific type of public keys and
4287 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4288 public key or certificate.
4290 * Implemented the GETKEY command to the server and to the
4291 client library and on user interface.
4293 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Made preliminary `make install' work.
4297 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4299 * Added SilcServerRekey context into silcd/idlist.h.
4301 * Added the PFS support as defined in the specification to the
4302 SKE protocol. Affected files lib/silcske/*.c.
4304 * Added `ske_group' field to the SilcServerRekey context to hold
4305 the number of the SKE group that is used with PFS in re-key.
4306 Affected file silcd/idlist.h.
4308 * Added PFS re-key support to the server. Affected file is
4311 * Added silc_protocol_cancel to cancel execution of the next
4312 state of the protocol. Affected file is
4313 lib/silccore/silcprotocol.[ch].
4315 * Added the re-key support with and without PFS to the client
4316 library. Re-key is performed once in an hour, by default.
4318 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4319 Added silc_client_rekey_callback and silc_client_rekey_final.
4320 Affected files are lib/silcclient/protocol.[ch] and
4321 lib/silcclient/client.[ch].
4323 * Removed the `hmac_key' and `hmac_key_len' fields from the
4324 SilcClientConnection structure; not needed. Affected file is
4325 lib/silcclient/client.h.
4329 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Do not ask whether user wants to use the negotiated private key
4332 for private messages, just use it. Affected file is
4333 silc/local_command.c.
4335 * Added `send_enc_key' and `enc_key_len' fields to the
4336 SilcIDListData structure since they are needed in the re-key
4337 phase. Affected file is silcd/idlist.[ch].
4339 * Implemented the simple re-key protocol into the server.
4340 Affected files silcd/server.c and silcd/protocol.[ch]. The
4341 re-key will be performed once in an hour, by default.
4343 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4344 Added silc_server_rekey, silc_server_rekey_callback and
4345 silc_server_rekey_final.
4347 * Removed Tunneled flag from the protocol. Updated the code
4348 and the specifications.
4350 * Adde `pfs' field to the SilcIDListData to indicate whether
4351 the PFS is to be performed in the re-key. Affected file is
4354 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4357 int64 of at least the xintXX size. If void * is less that 4
4358 bytes uint32 * will be used. Defined bool as boolean.
4360 * Changed _ALL_ unsigned long and unsigned int to uint32,
4361 unsgined short to uint16 in the source tree.
4363 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4364 not handle clients that has entry->data.registered == FALSE.
4365 They are not in the network anymore. Affected file is
4368 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * Implemented the sending of the SERVER_SIGNOFF notify in the
4371 server. Affected file is silcd/server.c.
4373 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4374 Added also silc_notify_payload_encode_args into the
4375 lib/silccore/silcnotify.[ch].
4377 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4378 Affected file silcd/packet_receive.c.
4380 * Implemented the SERVER_SIGNOFF notify handling in the client
4381 library. Affected file lib/silcclient/client_notify.c. Also,
4382 implemnted the printing of the SERVER_SIGNOFF info to the
4383 application. Affected file silc/client_ops.c.
4385 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4386 if the deleting was successful. Affected file silcd/idlist.[ch].
4388 * Added support for public key authentication in the connection
4389 authentication protocol in the client library. Affected file
4390 lib/silcclient/protocol.c.
4392 * Changed the server's silc_idlist_get_clients_by_* interface
4393 to support already allocated array so that new entries may be
4394 added to pre-allocated array. Affected file silcd/idlist.[ch].
4395 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4396 and command replies.
4398 * All command reply functions in the server now calls the
4399 pending command callback even if error occured. This way the
4400 error will be delivered to the client as well. Affected files
4401 silcd/command.c and silcd/command_reply.c.
4403 * Fixed INFO command to return local server's info if no server
4404 was provided. Affected file lib/silcclient/command.c.
4406 * Removed RESTART command for good. Updated the code and the
4409 * Rewrote parts of the task system. It is a bit simpler now.
4410 Removed unsued task priorities. The affected files are
4411 lib/silcutil/silctask.[ch].
4413 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Moved the USERS printing from the library to the application.
4416 Affected files lib/silcclient/command.c and silc/client_ops.c.
4418 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Added channel key re-key support. The re-key is perfomed
4423 only by the router and is done once in an hour. Added `rekey'
4424 field to the SilcChannelEntry in the server. Affected files
4425 silcd/server.c and silcd/idlist.h.
4427 * Added silc_task_unregister_by_context into the file
4428 lib/silcutil/silctask.[ch].
4430 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Added SILC_UMODE_GONE mode to indicate when the client is not
4433 present in the SILC network. Added also support to the local
4434 command AWAY that will set this mode. Added support of showing
4435 "xxx is gone" in WHOIS command. The USERS command shows the
4436 gone status as well.
4438 * Fixed setting server and router operator privileges in the
4439 server's UMODE command. Affected file silcd/command.c.
4441 * Merged the SKE KE1 and KE2 payloads into one payload. The
4442 new KE payload is equivalent to the old KE2 payload.
4444 Cleaned up the SKE Start Payload parsing. It now uses the
4445 simple buffer unformatting to do the parsing. A lot faster
4448 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4449 to the SKE that is used to indicate whether both of the SKE
4450 parties should perform authentication. By default only the
4451 responder performs authentication. By setting this flag also
4452 the initiator must do authentication. By default it is unset
4453 since in normal SKE case, client to server connection, only
4454 the responder should do authentication. When doing SKE between
4455 two clients both should perform authentication. Updated the
4456 code and the protocol specs.
4458 * A little fix to IDENTIFY command in the server. Search the
4459 client first by hash not nickname. Affected file is
4462 * Fixed the silc_client_close_connection to support closing
4463 the client to client connections wihtout deleting too much
4464 data. Affected file lib/silcclient/client.c.
4466 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4467 are received if protocol used to be active but is not anymore
4468 the application would crash due to NULL pointer dereference.
4469 Affected files silcd/server.c and lib/silcclient/client.c.
4471 * Added `hash' field to the SilcClientConnection to include
4472 the hash function negotiated in the SKE protocol.
4474 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4475 to set the channel founder authentication data. A client can
4476 claim the founder rights later by providing the authentication
4477 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4478 This way the channel founder can regain the channel founder
4479 privileges even it is left the channel. This works only on
4480 local server and the client must be connected to the same
4481 server to be able to regain the founder rights. Updated the
4482 protocol specs accordingly.
4484 Added support to the CMODE command in the client to set the
4485 founder auth data. Read the README to see how to set it.
4487 Added support to the CUMODE command to claim the founder
4488 rights. Read the README to see how to do it.
4490 Added support for the founder authentication to the Channel
4491 Entry in the server. Affected file silcd/idlist.h.
4493 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4494 server's CMODE command. Affected file silcd/command.c.
4496 * Added the following new functions into lib/silccore/silcauth.[ch]:
4497 silc_auth_get_method and silc_auth_get_data.
4499 * The server now saves the remote hosts public key to the
4500 SilcIDListData pointer. Affected file silcd/protocol.c.
4502 * The normal server now does not remove the channel entry from
4503 the cache if the founder authentication data is set. It used
4504 to remove it if the founder was the last one on the channel on
4505 the server and left the channel. The auth data is saved and
4506 if the channel is re-joined later the old entry is used with
4507 the old auth data. Affected files silcd/command_reply.c and
4510 * Removed the `pkcs' field from the SilcIDListData structure
4511 in the server; it is not used. Affected file silcd/idlist.h.
4513 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Fixed packet processing on slow links. Partial packets were
4516 never re-processed because the incoming data buffer was cleared
4517 by the application. Application must not directly clear the
4518 sock->inbuf, the packet processing routines handle it. Fixed
4519 this in client library and in server.
4521 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Fixed the WHOIS and IDENTIFY send reply function to really
4524 check whether to send list or just one entry. Affected file
4527 * Cleaned up the LEAVE command's channel key distribution. The
4528 affected file silcd/command.c.
4530 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4531 can enforce the channel mode as well. In that case the ID
4532 includes the ID of the server. The code now enforces the
4533 mode change if the router have different mode than the server.
4535 * The notify client operation with CMODE_CHANGE notify can now
4536 return NULL client_entry pointer if the CMODE was not changed
4537 by client. Application must check for this.
4539 * Added <Server ID> argument to INFO command to support server
4540 info fetching by Server ID.
4542 * Added silc_server_announce_get_channel_users to get assembled
4543 packets of channel users of the specified channel. Affected
4544 file silcd/server.[ch].
4546 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4547 was freed underneath the ID Cache.
4549 * Re-announce clients when the server received CHANNEL_CHANGE
4550 notify from the router. Affected file silcd/packet_send.c.
4552 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4555 crashed since it did not handle the fact that there is no cipher
4556 called "3" and didn't check the error condition. Now fixed.
4558 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4559 flag. It can be used to send message requests.
4561 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Implemented the RESTART command in the client.
4565 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4566 notice type messages. Added notice printing to the user
4569 * The channel keys are not re-generated if the channel's mode
4570 is PRIVKEY, ie private key on the channel exists. Affected
4571 files silcd/server.c and silcd/command.c.
4573 * Fixed a little bug in channel message delivery when channel
4574 private keys are set in the server. Affected file is
4575 silcd/packet_send.c.
4577 * Changed the setting on channel->on_channel = TRUE from the
4578 silc_client_save_channel_key to the JOIN command reply. The
4579 key payload is not received if the private channel key is set.
4580 Affected file lib/silcclient/command_reply.c and the
4581 lib/silcclient/client_channel.c.
4583 * When the CMODE_CHANGE notify is sent and the channel private
4584 key mode is removed the channel key must be re-generated in
4585 other cells as well. Added this support for the router in the
4586 silcd/packet_receive.c.
4588 * Added new local command NOTICE to send notice message on
4589 channel. Affected file silc/local_command.[ch].
4591 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Added new local command ME to the client. It is used to send
4594 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4595 some action. Affected file silc/local_command.[ch].
4597 * Changed channel_message and private_message client operations
4598 to deliver the message flags to the application. Added also
4599 the `flags' arguments to the silc_client_send_channel_message
4600 and silc_client_send_private_message functions. Affected file
4603 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Redefined the Private Message Payload to support private message
4606 keys and to support the new private message flags. Updated
4607 the protocol specs. Flags makes it possible to have for example
4608 CTCP style messages.
4610 * Added new type SilcPrivateMessagePayload and defined an API
4611 for it in the lib/silcclient/silcprivate.[ch].
4613 * Tested private message private keys successfully. Tested the
4614 private message key set, unset and list commands with the new
4617 * Redefined the Channel Message Payload to include the channel
4618 message flags (equal with private message flags) to support
4619 for example CTCP style messages.
4621 * Defined some of the message (for channel and private message)
4622 flags. Updated the protocol specs and added the flags to the
4623 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4625 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4627 * Added SilcKeyAgreementStatus type to the key agreement routines
4628 to indicate the current status and error if one occured.
4629 The status types are defined in the lib/silcclient/silcapi.h.
4631 * Added new local command KEY that is used to set and unset private
4632 keys for channels, set and unset private keys for private messages
4633 with remote clients and to send key agreement requests and
4634 negotiate the key agreement protocol with remote client. The
4635 key agreement is supported only to negotiate private message keys,
4636 it currently cannot be used to negotiate private keys for channels,
4637 as it is not convenient for that purpose.
4639 * Fixed a minor pending callback setting bug in the function
4640 silc_client_get_client_by_id_resolve, now the function works.
4641 Affected file lib/silcclient/idlist.c.
4643 * Added function silc_net_get_local_port to get local bound
4644 port by socket. Added to lib/silcutil/silcnet.[ch].
4646 * Added `sockets' and `sockets_count' fields to the SilcClient
4647 object. They hold the sockets of the listenning sockets in
4648 the client. Listenning sockets may be for example the key
4649 agreement server. Affected file lib/silcclient/client.[ch].
4650 Added functions the silc_client_add_socket and the
4651 silc_client_del_socket. They are exported to the application
4654 * Added ~./silc/clientkeys to support other client's public keys.
4656 * Renamed verify_server_key client operation to verify_public_key
4657 and added one argument to indicate the type of the connection
4658 (server, client etc.).
4660 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Added silc_server_connection_auth_request to handle the
4663 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4664 silcd/packet_receive.[ch].
4666 * Added silc_server_send_connection_auth_request into the
4667 silcd/packet_send.c to send the connection auth request packet.
4669 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4672 * Fixed the public key authentication in responder side in the
4673 server. The `auth_data' pointer includes the SilcPublicKey
4674 not the path to the public key. Affected file silcd/protocol.c.
4676 * Implemented the public key authentication in the initiator side
4677 in the server. Affected file silcd/protocol.c.
4679 * Removed the [RedirectClient] config section from the server
4680 configuration. Is not needed and I don't want to implement it.
4682 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * Cleaned up the CMODE command in the server. It now works
4685 correctly and supports all the modes defined in the protocol.
4686 Affected file is silcd/command.c.
4688 * Added `hmac_name' field to the SilcChannelEntry in the server
4689 to hold the default HMAC of the channel. It can be set when
4690 creating the channel (with JOIN command). Affected files
4693 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4694 type to indicate the change of the current cipher and hmac
4695 on the channel. Client can safely ignore the <cipher> argument
4696 (if it chooses to do so) since the CHANNEL_KEY packet will
4697 force the channel key change anyway. The <hmac> argument is
4698 important since the client is responsible of setting the new
4699 HMAC and the hmac key into use.
4701 * Fixed the CMODE command in the client library as well.
4703 * Tested CMODE command in router environment successfully.
4705 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * Show the version of the remote client (or server) when connecting
4708 to the server. It is logged to the log file. Affected file
4709 is silcd/protocol.c.
4711 * Fixed the KILLED notify handling in the client library. The
4712 client must be removed from all channels when receiving the
4715 Also, do not remove the client entry when giving the KILL
4716 command but when the KILLED notify is received.
4718 * Removed silc_idlist_find_client_by_nickname from the server.
4719 Not needed anymore. Affected files silcd/idlist.[ch].
4721 * Implemented the CHANNEL_CHANGE notify type handling to the
4722 server. Affected file silcd/server.c.
4726 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4728 * Added silc_server_send_notify_invite to send the INVITE
4729 notify between routers.
4731 * Implemented the INVITE command correctly to the server.
4733 * Implemented the INVITE notify type handling in the server.
4735 * Implemented the INVITE command to the client library and on the
4738 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Added function silc_server_get_client_resolve to find the
4741 client entry by ID from all ID lists and then resolve it
4742 (using WHOIS) if it cannot be found. Affected file is
4745 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Implemented the BAN command to the client library.
4749 * The JOIN command in the server now checks the invite list
4752 * Changed the silc_command_reply_payload_encode_va and the
4753 silc_command_payload_encode_va to support that if argument is
4754 NULL it ignores and checks the next argument. Affected file
4755 lib/silccore/silccommand.c.
4757 * Added silc_server_send_notify_ban to send the BAN notify
4758 type between routers.
4760 * Chaned the silc_notify_payload_encode to support that if
4761 argument is NULL it ignores and checks the next argument.
4762 Affected file lib/silccore/silcnotify.c.
4764 * Tested ban lists in router environment successfully.
4766 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4768 * Implemented BAN command to the server, in silcd/command.[ch].
4770 * Removed the BAN and INVITE_LIST modes from the CMODE command
4773 * Added function silc_string_match to regex match two strings.
4774 Affected files lib/silcutil/silcutil.[ch].
4776 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4778 * Redefined parts of the SilcChannelEntry in the server to support
4779 the new ban and invite lists.
4781 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4783 * Redefined the INVITE command. The same command can be used to
4784 invite individuals to the channel but also to manage the invite
4785 list of the channel (to add to and remove from the invite list).
4786 Updated the protocol specs.
4788 * Added new command SILC_COMMAND_BAN that can be used to manage
4789 the ban list of the channel. Updated the protocol specs.
4791 * Removed the channel modes: the SILC_CMODE_BAN and the
4792 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4793 in the CMODE command. The equivalent features are now available
4794 using INVITE and BAN commands. Updated the protocol specs.
4796 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4797 in the network about change in the current ban list. The notify
4798 type is not used by the client.
4800 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4801 support the invite lists.
4803 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4805 * Added new function silc_string_regexify that converts string
4806 including wildcard characters into regex string that can
4807 be used by the GNU regex library. Added into the file
4808 lib/silcutil/silcutil.[ch].
4810 Added silc_string_regex_combine to combine to regex strings
4811 into one so that they can be used as one regex string by
4812 the GNU regex library. Added into the file
4813 lib/silcutil/silcutil.[ch].
4815 Added silc_string_regex_match to match two strings. It returns
4816 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4818 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Imported GNU regex to the soruce tree into lib/contrib.
4821 Fixed some compiler warning from the regex.c.
4823 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Fixed MOTD command in the server to work in router environment.
4827 * Fixed the MOTD command in the client library to support
4828 the server argument in the command.
4830 * Added `nickname_len' argument to the silc_idlist_add_client
4831 in the server, as the `nickname' argument may be binary data
4834 * Added silc_idlist_get_channels to return all channels from
4837 * Implemented LIST command to the server. Affected file is
4840 * Implemented the LIST command to the client library and on the
4843 * Added [<user count>] argument to the LIST command reply.
4844 With private channels the user count is not shown.
4846 * Updated TODO and README.
4848 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * The client entry's data.registered must be TRUE even with
4851 global client entry on global client list. The data.registered
4852 is used to check whether the client is anymore in the network,
4853 for example with WHOWAS command so it must be valid.
4855 * Fixed the WHOWAS command in the server. It now actually works
4856 in router environment. Added function into silcd/command_reply.c
4857 silc_server_command_reply_whowas_save.
4859 * Added silc_idlist_purge function to the silcd/idlist.c
4860 to periodically purge the ID Cache.
4862 * Fixed INFO command in the server. It works now in router
4863 environment. Added <server name> argument to the INFO command
4864 reply. Updated the protocol specs.
4866 * Fixed minor bug in silc_idcache_purge to not purge if the
4867 expire value is zero.
4869 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4870 they were buggy because of the WHOWAS information.
4872 * Fixed local command MSG to handle the async resolving of
4873 the remote client properly. It used to fail the first MSG.
4874 Affected file silc/local_command.c.
4876 * Added `data_len' field to SilcIDCache context.
4878 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Update TODO. Todo in commands in the server.
4882 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4885 used by routers as broadcast packet to inform other routers
4886 about the changed user mode.
4888 Implemented the notify handling in the server. Affected file is
4889 silcd/packet_receive.c. Added the function
4890 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4892 * Added new generic Channel Payload and deprecated the New Channel
4893 Payload. The New Channel Payload is now the generic Channel
4896 * Added new argument `mode' to the silc_server_send_new_channel
4897 as it is required in the Channel Payload now.
4899 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4900 and created a new and real SilChannelPayload to represent the
4901 new generic Channel Payload. Implemented the encode/decode
4902 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4904 * Added silc_server_get_client_channel_list to return the list
4905 of channels the client has joined for WHOIS command reply.
4906 Affected file silcd/server.[ch].
4908 * Implemented the channel list sending in the WHOIS command reply
4909 in server and in the client.
4911 Implemented the channel list displaying on the user interface
4912 as well. Affected file silc/client_ops.c.
4914 * Added silc_channel_payload_parse_list to parse list of Channel
4915 Payloads. It returns SilcDList list of SilcChannelPayloads.
4916 Client for example can use this function to parse the list of
4917 channels it receives in the WHOIS command reply. The caller
4918 must free the list by calling silc_channel_payload_list_free.
4919 Affected files lib/silccore/silcchannel.[ch].
4921 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Added one new argument <user mode> to the WHOIS command reply
4924 to return the mode of the user in SILC. Updated the protocol
4927 Implemented it to the server and client.
4929 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Fixed the mode printing on the user interface on joining.
4932 Affected file silc/client_ops.c.
4934 * Implemented the UMODE command and user modes in general to the
4935 client library and to the user interface.
4937 * Implemented the UMODE command to the server.
4939 * The server now sends UNKNOWN_COMMAND error status if client sends
4940 unknown command. Affected file silcd/command.c.
4942 * All server commands now handle the command identifier the right
4943 way when sending the command reply to the client. The client can
4944 use to identify the command replies with the identifier.
4946 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Added silc_server_get_client_route to resolve the route to
4949 the client indicated by the client ID. Affected file is
4952 * Added silc_server_relay_packet as general function to relay
4953 packet to arbitrary destination. This deprecates functions
4954 like _send_private_message_key, _relay_notify etc. Affected
4955 file is silcd/packet_send.[ch].
4957 Removed silc_server_send_key_agreement,
4958 silc_server_send_private_message_key and
4959 silc_server_packet_relay_notify functions from the file
4960 silcd/packet_send.[ch].
4964 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4965 server. Affected file silcd/packet_receive.[ch].
4967 * Implemented the KILL command to the client. Implemented the
4968 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4969 Affected files lib/silcclient/command[_reply].c and
4970 lib/silcclient/client_notify.c. Implemented the KILL notify
4971 printing in the user inteface.
4973 * Fixed a lot silc_parse_nick memory leaks from the client
4974 library in the file lib/silcclient/command.c.
4976 * Changed the silc_server_send_notify_on_channels's `sender'
4977 argument from SilcSocketConnection to SilcClientEntry to
4978 check the sender as entry and not as connection object and not
4979 to send to the client provided as argument. The affected file
4980 is silcd/packet_send.[ch].
4982 * The notify packets that are destined directly to the client used
4983 to not to be processed by the server. Now changed that and the
4984 server processes all notify packets. After relaying the packet
4985 to the client the notify packet is processed in the server.
4987 * The silc_server_free_client_data now checks whether there is
4988 pending outgoing traffic for the client and purges the data to
4989 the network before removing the client entry.
4991 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4994 an client is killed from the SILC Network. Updated the protocol
4997 Added new function silc_server_send_notify_killed to the
4998 silcd/packet_send.[ch].
5000 * Added function silc_server_packet_relay_notify to relay notify
5001 packets that are destined directly to a client. In this case
5002 the server does not process the notify packets but merely relays
5003 it to the client. Affected file silcd/packet_send.[ch].
5005 Added also silc_server_packet_process_relay_notify to check
5006 whereto relay the notify. Affected file is
5007 silcd/packet_receive.[ch].
5009 * Implemented the KILL command to the server.
5013 * Added the backup schema desgined last fall to the protocol
5014 specs for everyone to see. The specification is in the
5015 *-spec-xx.txt draft and the packet type definitions for the
5016 backup routers is in *-pp-xx.txt draft. Thusly, added also
5017 new packet type SILC_PACKET_CELL_ROUTERS.
5019 * A big security problem in the implementation discovered. The
5020 signoff of an client did not cause new channel key generation
5021 which it of course should've done. The channel keys must be
5022 always re-generated when client leaves (or signoffs) the channel.
5023 The silc_server_remove_from_channels funtion now handles
5024 the channel key re-generation.
5026 * Added `sender' argument to the silc_server_send_notify_on_channels
5027 to not to send the client provided as argument. Affected file
5028 silcd/packet_send.[ch].
5030 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5032 * Implemented OPER and SILCOPER commands into the server and
5035 * Added silc_auth_verify and silc_auth_verify_data to verify
5036 the authentication directly from the authentication payload.
5037 It supports verifying both passphrase and public key based
5038 authentication. Affected file lib/silccore/silcauth.[ch].
5040 * Added `hash' field to the SilcIDListData structure. It is the
5041 hash negotiated in the SKE protocol. Affected file is
5044 * Slight redesigning of the SilcAuthPayload handling routines.
5045 Do not send SilcPKCS but SilcPublicKey as argument.
5047 * Implemented the public key authentication support to the
5048 serverconfig. The public key is loaded from the provided path
5049 and saved as authentication data to void * pointer. Thus,
5050 changed the unsigned char *auth_data to void *auth_data;
5052 * Fixed SHUTDOWN command to send the reply before the server
5053 is shutdown. :) Affected file silcd/command.c.
5055 * Fixed fatal bug in CONNECT command. The hostname was invalid
5056 memory and server crashed. Affected file silcd/command.c.
5058 * Fixed fatal bug in CLOSE command. The server_entry became
5059 invalid but was referenced later in the command. Affected file
5062 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Fixed fatal bug in failure packet handling. Server ignored
5065 the failure and thus crashed when it came.
5069 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5071 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5072 that the command may be executed only once in (about) 2 seconds.
5073 The old SILC_CF_LAG flag is same but allows command bursts up
5074 to five before limiting.
5076 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5077 server code. Various commands now includes the CF_LAG_STRICT
5078 flag to disallow any kind of miss-use of the command.
5080 * Fixed the silc_buffer_unformat to not to allocate any data
5081 if the length of the data is zero. It used to allocate the
5082 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5084 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Changed the format of AdminConnection configuration section
5087 in the server. Added username of the admin to the format.
5088 Affected files silcd/serverconfig.[ch].
5090 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5091 to return admin configuration data by host, username and/or
5094 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Implemented WHOWAS command to the server. Added the functions:
5098 silc_server_command_whowas_parse,
5099 silc_server_command_whowas_send_reply,
5100 silc_server_command_whowas_from_client and
5101 silc_server_command_whowas_from_server
5103 * Added <Client ID> argument to the WHOWAS command reply. Updated
5104 the protocol specs accordingly.
5106 * Implemented WHOWAS command and command_reply to the client
5109 Implemented the WHOWAS printing on the user interface.
5111 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Added new argument to the WHOWAS command reply, the real name.
5114 It is an optional argument. Updated the protocol specs.
5116 * Added SilcIDCacheDestructor callback that is registered when
5117 the SilcIDCache is allocated. The callback is called when
5118 an cache entry in the ID Cache expires, or is purged from the
5119 cache. Added into lib/silccore/idcache.[ch].
5121 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5122 to destruct the client entries when the cache entry expires.
5123 Other ID Cache's in server and in the client library ignores
5126 * If the ID Cache entry's `expire' field is zero then the entry
5127 never expires. Added boolean `expire' argument to the
5128 silc_idcache_add function in the lib/silccore/idcache.[ch].
5129 If it is TRUE the default expiry value is used.
5131 * Added silc_server_free_client_data_timeout that is registered
5132 when client disconnects. By default for 5 minutes we preserve
5133 the client entry for history - for WHOWAS command.
5135 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Added support to the server to enforce that commands are not
5138 executed more than once in 2 seconds. If server receives
5139 commands from client more frequently, timeout is registered
5140 to process the commands. Affected file silcd/command.c.
5141 Added new function silc_server_command_process_timeout.
5143 * Changed NICK_NOTIFY handling in client library to check that
5144 if the client's nickname was changed, so there is no need to
5145 resolve anything from the server.
5147 * Removed error printing from the WHOIS and IDENTIFY commands.
5148 If error occurs then it is ignored silently in the client library.
5149 The application, however, may map the received error to
5150 human readable error string. The application currently maps
5151 the NO_SUCH_NICKNAME error to string.
5153 * Made the command status message public to the application. Moved
5154 them from lib/silcclient/command_reply.c to
5155 lib/silcclient/command_reply.h. The application can map the
5156 received command status to the string with the
5157 silc_client_command_status_message function.
5159 * Added check to the server to check that client's ID is same
5160 as the Source ID in the packet the client sent. They must
5163 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Added dist-bzip hook to the Makefile.am to make bzip2
5166 compressed distributions.
5168 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * Server now enforces the maximum length for the nickname and
5171 the channel as protocol specification dictates. 128 bytes for
5172 nickname and 256 bytes for channel name.
5174 * Moved the WHOIS printing to the application. The client libary
5175 does not print out the WHOIS information anymore, the application
5176 must do it. Renamed silc_client_command_reply_whois_print to
5177 the silc_client_command_reply_whois_save.
5179 The client's idle time is also sent to the application now, and
5180 the idle is shown on screen.
5182 * Added silc_client_command_reply_identify_save to save the
5183 received IDENTIFY entries.
5185 * Do not check for channel private keys in message sending and
5186 reception if the channel does not have the PRIVKEY mode set.
5187 Affected file lib/silclient/client_channel.c.
5189 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5192 just surfaced after chaning the JOIN procedure.
5194 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Added silc_client_get_clients_by_list to get client entries
5197 from Client ID list, that is returned for example by JOIN
5198 and USERS command replies. The application should use this
5199 function for example when JOIN command reply is received to
5200 resolve the clients already on the channel (library does not
5201 do that anymore as USERS command reply is not used in the JOIN
5202 procedure anymore). Affected files lib/silcclient/silcapi.h and
5203 lib/silcclient/idlist.c.
5205 * JOIN command reply and USERS command reply returns now SilcBuffer
5206 pointers instead of unsigned char pointers when returning
5207 the client list and mode list.
5209 * Added <Client ID> argument to the JOIN command reply, mainly
5210 for the server to identify for which client the command was
5211 originally sent. Updated protocol specs accordingly.
5213 * Added SilcDlist private_key pointer to the SilcChannelEntry
5214 in the client to support the channel private keys. Affected
5215 file is lib/silcclient/idlist.h.
5217 * Added SilcChannelPrivateKey argument to the function
5218 silc_client_send_channel_message so that application can choose
5219 to use specific private ke if it wants to. If it is not provided,
5220 the normal channel key is used, unless private keys are set.
5221 In this case the first (key that was added first) is used
5222 as the encryption key.
5224 * Implemented the support for channel private key handling.
5225 Implemented the following functions:
5227 silc_client_add_channel_private_key,
5228 silc_client_del_channel_private_keys,
5229 silc_client_del_channel_private_key,
5230 silc_client_list_channel_private_keys and
5231 silc_client_free_channel_private_keys
5233 Affected file lib/silcclient/client_channel.c.
5235 * Added the support for the private keys in the channel message
5236 sending and encryption and in the message reception and
5237 decryption. Affected funtions are
5238 silc_client_send_channel_message and silc_client_channel_message.
5240 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Added SKE's key verify callback to the client library's
5243 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5245 * Removed the statement that server (or router) must send USERS
5246 command reply when joining to the channel so that the client
5247 knows who are on the channel. Instead, the client list and
5248 client's mode list is now sent in the JOIN command reply to the
5249 client who joined channel. This is better solution.
5251 * Added function silc_server_get_users_on_channel and function
5252 silc_server_save_users_on_channel to the silcd/server.[ch].
5254 * Removed function silc_server_command_send_users from the
5257 * Do not show topic on the client library anymore. The topic is
5258 sent in the command reply notify to the application and the
5259 application must show the topic now.
5261 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5263 * Added client searching by nickname hash into the IDENTIFY and
5264 WHOIS commands in the server as they were clearly missing from
5265 them. Affected file is silcd/command.c.
5267 * Fixed a bug in private message receiving in the client library.
5268 The remote ID was freed and it wasn't supposed, now it is
5271 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Minor fix to the channel payload; allocate the data area, as it
5274 needs to be of specific length.
5276 * If the key agreement port is zero then the operating
5277 system will define the bound port. Affected files are
5278 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5280 * Added new function silc_channel_payload_decrypt into the file
5281 lib/silccore/silcchannel.[ch].
5283 * Moved the channel message etc, check from silc_packet_decrypt
5284 to applications. The library calls now a generic
5285 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5286 when the packet is either normal or special. This was done to
5287 allow more wide range of checking that was not allowed when
5288 the code was in library. Now applications can do virtually any
5289 checks to the packet and return to the library the decision how
5290 the packet should be processed. Affected files are
5291 lib/silccore/silcpacket.[ch].
5293 Added silc_server_packet_decrypt_check to the server and
5294 silc_client_packet_decrypt_check to the client library.
5296 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5297 to send with specified source and destination information.
5299 * Channel message delivery between routers was broken after the
5300 channel key distribution was fixed earlier. The channel key
5301 was used be to distributed to other routers as well which is not
5302 allowed by the protocol. Now this is fixed and channel keys
5303 really are cell specific and the channel message delivery between
5304 routers comply with the protocol specification.
5306 * Fixed various commands in server to check also the global list
5307 for the channel entry and not just the local list. The affected
5308 file silcd/command.c.
5310 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Added assert()s to buffer formatting and unformatting routines
5313 to assert (if --enable-debug) when error occurs. Affected
5314 file: lib/silcutil/silcbuffmt.c.
5316 * Changed to auto-reconnect to check whether the remote host is
5317 router and register the re-connect timeout if it is. It used
5318 to check that whether we are normal server, but router must do
5319 auto-reconnect with another router as well. Affected file
5322 * Removed the [<key len>] option from CMODE command as the cipher
5323 name decides the key length, nowadays. See the defined ciphers
5324 from the protocol specification.
5326 * Added [<hmac>] option to the CMODE command to define the HMAC
5327 for the channel. Added SILC_CMODE_HMAC channel mode.
5329 * Added [<hmac>] option for the JOIN command so that user can
5330 select which HMAC is used to compute the MACs of the channel
5333 * Added Hmac field to the Channel Message Payload. The integrity
5334 of plaintext channel messages are now protected by computing
5335 MAC of the message and attaching the MAC to the payload. The
5336 MAC is encrypted. Now, it is clear that this causes some
5337 overhead to the size of the packet but rationale for this is that
5338 now the receiver can verify whether the channel message decrypted
5339 correctly and also when private keys are set for the channel the
5340 receiver can decrypt the packet with several keys and check from
5341 the MAC which key decrypted the message correctly.
5343 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5344 lib/silccrypt/silccipher.[ch].
5346 * Added silc_hash_len to return the digest length into the
5347 lib/silcrypt/silchash.[ch].
5349 * Rewrote parts of Silc Channel Payload interface in the
5350 lib/silccore/silcchannel.[ch]. The encode function now also
5351 encrypts the packet and parse function decrypts it.
5353 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Fixed a minor formatting bug in the SKE's key material processing.
5356 It actually might have processed the keys wrong way resulting
5359 * Redefined the mandatory HMAC algorithms and added new algorithms.
5360 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5361 and hmac-md5 truncated to 96 bits. The mandatory is now
5362 hmac-sha1-96. Rest are optional (including the one that used
5363 to be mandatory). Rationale for this is that the truncated HMAC
5364 length is sufficient from security point of view and can actually
5365 make the attack against the HMAC harder. Also, the truncated
5366 HMAC causes less overhead to the packets. See the RFC2104 for
5369 * Added new [hmac] configuration section. The SKE used to use
5370 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5371 is of course wrong. The official names that must be proposed in
5372 the SKE are the ones defined in the protocol specification
5373 (hmac-sha1-96 for example). The user can configure any hmac
5374 using any hash function configured in the [hash] section. At
5375 least, the mandatory must be configured.
5377 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5379 * Added HMAC list to the SKE proposal list. It has now both
5380 hash algorithm list and HMAC list. This makes the protocol
5381 incompatible with previous versions. The SKE now seems to work
5382 the way it is supposed to work, for the first time actually.
5384 * Defined plain Hash algorithms to the protocol specification.
5387 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Implemented support for key agreement packets into the server.
5390 Added functions silc_server_key_agreement and
5391 silc_server_send_key_agreement. Other than these functions,
5392 server has nothing to do with this packet.
5394 * Added support for private message key packets into the server.
5395 Added functions silc_server_private_message_key and
5396 silc_server_send_private_message_key.
5400 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5401 called in the protocol's final callback instead in the END
5402 protocol state. This makes a little more sense and in the same
5403 time in client we can use the same protocol routines for normal
5404 key exchange and to key agreement packet handling as well.
5406 * Added to both client's and server's KE protocol context the
5407 SilcSKEKeyMaterial pointer to save the key material. We will
5408 bring the key material to the protocol's final callback by doing
5409 this. The final callback must free the key material.
5411 * Added SKE's packet_send callback into client's KE protocol
5412 context so that the caller can choose what packet sending function
5413 is used. This way we can use different packet sending when
5414 doing normal SKE when doing key agreement packet handling (in
5415 the key agreement packet handling we do not want to encrypt
5418 * Implemented the responder side of the key agreement routines
5419 in the client. The client can now bind to specified port and
5420 accept incoming key negotiation. The key material is passed
5421 to the application after the protocol is over.
5423 * Implemented the processing of incoming Key Agreement packet
5424 in the client. Added function silc_client_key_agreement to
5427 * Implemented the intiator side of the key agreement routines
5428 in the client. The client can now initiate key agreement with
5429 another remote client. The key material is passed to the
5430 application after the protocol is over.
5432 * Created client_keyagr.c to include all the key agreement
5435 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5436 SILC_TASK_CALLBACK except that it is not static.
5438 * Created client_notify.c and moved the Notify packet handling
5439 from the client.[ch] into that file.
5441 * Created client_prvmsg.c and moved all private message and
5442 private message key routines from the client.[ch] into that file.
5444 * Create client_channel.c and moved all channel message and
5445 channel private key routines from the client.[ch] into that file.
5447 * Changed silc_client_get_client_by_id_resolve to resolve with
5448 WHOIS command instead of IDENTIFY command, in the file
5449 lib/silclient/idlist.c.
5451 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Implemented the SKE's responder side to the Client library.
5455 * When FAILURE is received to the protocol do not trust it
5456 blindly. Register a timeout to wait whether the remote closes
5457 the connection as it should do it, only after that process the
5458 actual failure. This was changed to both client and server.
5460 * Added client_internal.h to include some of the structures
5461 there instead of client.h in lib/silcclient/.
5463 * Added function silc_task_unregister_by_callback to unregister
5464 timeouts by the callback function.
5466 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * Some "Incomplete WHOIS info" errors has been appearing on the
5469 log files. Took away the entry->userinfo check from WHOIS
5470 reply sending. The entry->userinfo is now " " if client did not
5471 provide one. I thought this was fixed earlier but something
5472 is wrong still. Let's see if the error still appears.
5474 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Fixed a minor bug in the login when the channel key is
5477 re-generated in the server. It used to generate the key in
5478 wrong order and thus caused problems in the channel traffic.
5480 * Fixed a minor bug in channel key distsribution after
5481 KICK command. The key was not sent to the router even though
5484 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Added silc_ske_process_key_material_data as generic routine
5487 to process any key material as the SILC protocol dictates. The
5488 function is used by the actual SKE library but can be used by
5489 applications as well. This relates to the private message keys
5490 and the channel private keys since they must be processed the
5491 same way the normal SILC session keys. The protocol dictates
5492 this. Affected files: lib/silcske/silcske.[ch].
5494 Added also silc_ske_free_key_material to free the
5495 SilcSKEKeyMaterial structure.
5497 * Defined silc_cipher_set_key function to set the key for
5498 cipher without using the object's method function. The affected
5499 files: lib/silccrypt/silccipher.[ch].
5501 * Implemented silc silc_client_add_private_message_key,
5502 silc_client_add_private_message_key_ske,
5503 silc_client_del_private_message_key,
5504 silc_client_list_private_message_keys and
5505 silc_client_free_private_message_keys functions in the
5508 Added functions silc_client_send_private_message_key to send
5509 the Private Message Key payload and silc_client_private_message_key
5510 to handle incoming Private Message Key payload.
5512 * Added Cipher field to the Private Message Key payload to set
5513 the cipher to be used. If ignored, the default cipher defined
5514 in the SILC protocol (aes-256-cbc) is used.
5516 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Removed lib/silcclient/ops.h file.
5520 Redefined parts of the SILC Client Library API. Created new
5521 file silcapi.h that deprecates the ops.h file and defines the
5522 published Client Library API. Defined also private message key
5523 API and channel private key API into the file.
5525 This is the file that the application must include from the
5526 SILC Client Library. Other files need not be included by
5527 the application anymore.
5529 * Added new key_agreement client operation callback and also
5530 defined the Key Agreement library API for the application.
5532 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5534 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5535 is used by clients to request key negotiation between another
5536 client in the SILC network. If the negotiation is started it
5537 is performed using the SKE protocol. The result of the
5538 negotiation, the secret key material, can be used for example
5539 as private message key.
5541 Implemented the Key Agreement payload into the files
5542 lib/silccore/silauth.[ch].
5544 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Redefined ciphers for the SILC protocol. Added some new ciphers
5547 and defined the key lengths for the algorithms. Changed the
5548 code accordingly. The default key length is now 256 bits.
5550 * Fixed SKE key distribution function silc_ske_process_key_material
5551 when the key length is more than 128 bits. The default key
5552 length in SILC is now 256 bits.
5554 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5555 to indicate unsupported algorithm.
5557 * Renamed rijndael.c to aes.c and all functions as well.
5559 * Fixed a long standing channel key setting bug in client library.
5560 Weird that it has never surfaced before.
5562 * Fixed bug in channel deletion. If the entire channel is removed
5563 then it must also delete the references of the channel entry
5564 from the client's channel list as the client's channel entry and
5565 the channel's client entry share same memory.
5567 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5569 * Implemented CONNECT and SHUTDOWN commands in the client.
5571 * Implemented CLOSE command to the client.
5573 * Added the function silc_idlist_find_server_by_name into the
5574 files silcd/idlist.[ch].
5576 Added the function silc_idlist_find_server_by_conn into the
5577 files silcd/idlist.[ch].
5579 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * DIE command was renamed to SHUTDOWN. Updated the both code
5584 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5585 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5587 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5590 * Added function silc_server_create_connection function to create
5591 connection to remote router. My server implementation actually
5592 does not allow router to connect to normal server (it expects
5593 that normal server always initiates the connection to the router)
5594 so the CONNECT command is only good for connecting to another
5597 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5599 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5600 or some other client was kicked from the channel.
5602 Implemented the handling of the notify type to both client
5605 Implemented silc_server_send_notify_kicked to send the KICKED
5606 notify. It is used to send it to the server's primary router.
5608 * Implemented the KICK command into server and client.
5610 * Added `query' argument to the silc_idlist_get_client function
5611 to indicate whether to query the client from server or not if
5614 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5615 to indicate that the client is not channel founder.
5619 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Removed the rng context from SilcPacketContext structure and
5622 changed that the packet routine uses the Global RNG API.
5624 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Added support for quit message that client can "leave" on the
5627 channel when it quits the SILC. It is ditributed inside the
5628 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5630 Added silc_server_free_client_data that will take the
5631 signoff message as argument.
5633 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5635 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5637 * Updated parts of the protocol specification to keep it up
5640 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5643 payloads in one packet.
5645 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5646 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5647 use now the new List flag.
5649 * Also deprecated the following packet types: REPLACE_ID,
5650 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5652 * Added list support for Notify packet in server.
5654 * Added silc_server_send_notify_channel_change to send the
5655 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5656 the silc_server_send_replace_id.
5658 * Added silc_server_send_notify_nick_change to send the
5659 NICK_CHANGE notify type. Deprecates the function
5660 silc_server_send_replace_id.
5662 * Added silc_server_send_notify_join to send the JOIN notify type.
5663 Deprecates the function silc_server_send_new_channel_user.
5665 * Added silc_server_send_notify_leave to send LEAVE notify type.
5666 Deprecates the function silc_server_send_remove_channel_user.
5668 * Added silc_server_send_notify_cmode and
5669 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5670 types. Deprecates the silc_server_send_set_mode function.
5672 * Added SERVER_SIGNOFF notify type to indicate that server has
5673 quit. This means that all clients on the channel from that
5674 server will drop. This can be also used when netsplit happens.
5676 Deprecated REMOVE_ID packet type since it is not needed anymore
5679 Added silc_server_send_notify_server_signoff to send the
5680 SERVER_SIGNOFF notify type. Deprecates the function
5681 silc_server_send_remove_id.
5683 Added also silc_server_send_notify_signoff to send the
5684 SIGNOFF notify type.
5686 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5687 SILC protocol from this day on. Changed the protocol
5688 specification as well.
5690 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5691 notify type. It is used between routers to notify about
5692 topic changes on a channel.
5694 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5697 * Partly updated the protocol specification to comply with the
5698 changes now made. It is still though a bit outdated.
5700 * The JOIN notify type now takes one extra argument <Channel ID>.
5701 The packet used to be destined to the channel but now the
5702 JOIN type may be sent as list thus it is impossible to
5703 destine it to any specific channel. By adding this argument
5704 it is again possible.
5706 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Added CREDITS file. The CHANGES and CREDITS file will appear
5709 in the distribution as well.
5711 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5713 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5714 types in the server's silcd/packet_receive.c.
5716 * Implemented CMODE and CUMODE to work in router environment.
5718 * Fixed minor encoding and decoding buglet from the
5719 lib/silccore/silcmode.c.
5721 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5724 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5726 * Changed all SilcConfigServer* and silc_config_server* to
5727 SilcServerConfig* and silc_server_config*, respectively.
5730 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Associated the ID (client or server ID) to the Authentication
5733 Payload to avoid any possibility of forging. Updated the
5734 protocol specification and the code accordingly.
5736 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * The RSA key length is now save to the RsaKey context in the
5739 key generation process in lib/silccrypt/rsa.c. The key length
5740 is now used to figure out the maximum size of the block allowed
5741 to be encrypted/signed.
5743 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5744 is equivalent to the silc_mp_mp2bin but does not allocate any
5747 * Changed silc_mp_mp2bin API to take length argument. If it is
5748 non-zero then the buffer is allocated that large. If zero, then
5749 the size is approximated using silc_mp_sizeinbase, which however
5752 * Created Global RNG API which is global RNG that application can
5753 initialize. After initializing, any routine anywhere in the
5754 code (including library) can use RNG without allocating a new
5755 RNG object. This was done to allow this sort of use of the
5756 RNG in code that has no chance to allocate RNG object. All
5757 applications currently allocate this and many routines in the
5758 library use this. Affected file lib/silccrypt/silcrng.[ch].
5760 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5761 it to use the Global RNG API.
5763 * Defined Authentication Payload into protocol specification that
5764 is used during SILC session to authenticate entities. It is
5765 used for example by client to authenticate itself to the server
5766 to obtain server operator privileges.
5768 Implemented this payload into the lib/silccore/silcauth.[ch].
5769 Implemented also routines for public key based authentication
5770 as the new protocol specification dictates.
5772 Moved definitions of different authentication methods from
5773 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5775 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5776 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5777 silc_pkcs_verify_with_hash functions into the file
5778 lib/silccrypt/silcpkcs.[ch].
5780 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * The client entry's userinfo pointer must be always valid.
5783 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5784 will fail since it requires the userinfo. Now, the userinfo
5785 is allocated as "" if actual userinfo does not exist. Actually,
5786 it must exist and it is totally Ok to drop client connections
5787 that does not announce the userinfo. However, we will make
5788 this workaround for now.
5790 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5791 to return the remote port by socket.
5793 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5796 SILC_SERVER_PENDING_EXEC and added an new macro
5797 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5798 data or when error occurs while processing the pending command.
5800 Added new argument `destructor' into silc_server_command_pending
5801 and to the SilcServerCommandPending object. This destructor is
5802 now called after calling the pending callback or if error occurs
5803 immediately. If error occurs the actual pending callback won't
5804 be called at all - only the destructor. The destructor may be
5805 NULL if destructor is not needed.
5807 All this applies for client library code as well. Similar
5808 changes were made there as well for the pending commands.
5810 In the client, the application must now allocate the
5811 SilcClientCommandContext with the silc_client_command_alloc
5814 * Added reference counter to the SilcServerCommandContext. Added
5815 function silc_server_command_alloc and silc_server_command_dup
5818 Same type of functions added to the client library for the same
5821 * Removed the cmd_ident from IDListData away since it is now
5822 global for all connections. It is the command identifier used
5823 in command sending and with pending commands. The affected file
5826 * Added reference counter to the SilcSocketConnection objecet to
5827 indicate the usage count of the object. The object won't be
5828 freed untill the reference counter hits zero. Currently only
5829 server uses this, and client ignores it. The client must be
5830 set to use this too later. The affected files are
5831 lib/silccore/silcsockconn.[ch]. Added also the function
5832 silc_socket_dup to increase the reference counter.
5834 This was mainly added because it is possible that the socket
5835 is removed underneath of pending command or other async
5836 operation. Now it won't be free'd and proper DISCONNECTING
5837 flags, etc. can be set to avoid sending data to connection that
5838 is not valid anymore.
5840 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5841 the connection. After that it sets SILC_SET_DISCONNECTED.
5842 It is, however, possible that the socket data is not still freed.
5843 The silc_server_packet_process now checks that data is not
5844 read or written to connection that is DISCONNECTED. The socket
5845 get's freed when the reference counter hits zero.
5847 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Changed the client operation API: channel_message operation's
5850 `sender' is now the client entry of the sender, not the nickname
5851 and the `channel' is the channel entry, not the channel name.
5853 In the private_message operation the `sender' is now also the
5854 client entry of the sender not the nickname.
5856 Affected file is lib/silcclient/ops.h and all applications
5857 using the client operations.
5859 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Moved the calling of ops->connect() from connect_to_server_final
5862 into receive_new_id functin since that is the point when the
5863 client is actually allowed to send traffic to network. The
5864 affected file is lib/silcclient/client.c.
5866 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5869 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5870 (if needs broadcasting) instead of broadcasting the packets one
5871 by one which would make a burst in the network traffic.
5873 * Added `broadcast' argument to the functions in silcd/server.[ch]
5874 silc_server_create_new_channel[_with_id] to indicate whether
5875 to send New Channel packet to primary router.
5877 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Added new function into the silcd/server.[ch] files:
5880 silc_server_create_new_channel_with_id to create new channel with
5881 already existing Channel ID.
5883 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5884 lib/silccore/silcpacket.h. This packet is used t send list of
5885 Set Mode payloads inside one packet. Server uses this to set
5886 the modes for the channels and clients on those channels, that it
5887 announced to the router when it connected to it. The protocol
5888 specification has been updated accordingly.
5890 * The silc_server_new_channel did not handle the packet coming
5891 from normal server as it normally does not send that. However,
5892 when it announces its channels it does send it. Implemented
5893 the support for that.
5895 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5896 into the file lib/silccore/id.h.
5898 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Fixed memory leaks in the functions silc_idlist_del_client,
5901 silc_idlist_del_channel and silc_idlist_del_server in the file
5902 silcd/idlist.c. All of those leaked like a sieve.
5904 * Fixed some small memory leaks in the client's function
5905 silc_client_notify_by_server.
5907 * Added functions into silcd/server.c: silc_server_announce_clients,
5908 silc_server_announce_channels and silc_server_announce_server.
5909 These functions are used by normal and router server to announce
5910 to its primary router about clients, channels and servers (when
5911 router) that we own. This is done after we've connected to the
5914 These functions effectively implements the following packet types:
5915 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5916 and SILC_PACKET_NEW_ID_LIST.
5918 * Added new functions into the silcd/packet_receive.[ch]:
5919 silc_server_new_id_list, silc_server_new_channel_list and
5920 silc_server_new_channel_user_list to handle the incoming
5921 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5923 * Added support of changing Channel ID in the function
5924 silc_server_replace_id. If the server that announces a channel
5925 to the router already exists in the router (with same name but
5926 with different Channel ID), router is responsible to send
5927 Replace ID packet to the server and force the server to change
5928 the Channel ID to the one router has.
5930 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5931 client that the Channel ID has been changed by the router. The
5932 normal server sends this to the client. Client must start using
5933 the new Channel ID as the channel's ID.
5935 Implemented handling of this new type into lib/silcclient/client.c
5936 into the function silc_client_notify_by_server.
5938 * Added new function silc_idlist_replace_channel_id into the files
5939 silcd/idlist.[ch] to replace the Channel ID.
5941 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5943 * Call silc_server_command_identify_check always when processing
5944 the IDENTIFY command in silcd/command.c
5946 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5948 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5949 send keepalive packets. The packet can be sent by clients,
5950 servers and routers.
5952 Added function silc_socket_set_heartbeat into the file
5953 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5954 If not set, the heartbeat is not performed. The actual
5955 heartbeat is implemented in the low level socket connection
5956 library. However, application is responsible of actually
5959 Added silc_server_send_heartbeat to send the actual heartbeat
5960 packet into silcd/packet_send.[ch]. Server now performs
5961 keepalive with all connections.
5963 * Added silc_task_get_first function into lib/silcutil/silctask.c
5964 to return the timeout task with shortest timeout. There was a bug
5965 in task unregistration that caused problems. TODO has been
5966 updated to include that task system must be rewritten.
5968 * The client library will now resolve the client information when
5969 receiving JOIN notify from server for client that we know but
5970 have incomplete information.
5972 * Rewrote parts of silc_server_remove_from_channels and
5973 silc_server_remove_from_one_channel as they did not remove the
5974 channel in some circumstances even though they should've.
5976 * Encryption problem encountered in server:
5978 The LEAVE command used to send the Channel Key packet to the
5979 router immediately after generating it. However, the code
5980 had earlier sent Remove Channel user packet but not immediately,
5981 ie. it was put to queue. The order of packets in the router
5982 was that Channel Key packet was first and Remove Channel User
5983 packet was second, even though they were encrypted in the
5984 reverse order. For this reason, MAC check failed. Now, this
5985 is fixed by not sending the Channel Key packet immediately but
5986 putting it to queue. However, this is more fundamental problem:
5987 packets that are in queue should actually not be encrypted
5988 because packets that are sent immediately gets encrypted
5989 actually with wrong IV (and thus MAC check fails). So, packets
5990 that are in queue should be encrypted when they are sent to
5991 the wire and not when they put to the queue.
5993 However, the problem is that the current system has not been
5994 designed to work that way. Instead, the packet is encrypted
5995 as soon as possible and left to the queue. The queue is then
5996 just purged into wire. There won't be any fixes for this
5997 any time soon. So, the current semantic for packet sending
6000 o If you send packet to remote host and do not force the send
6001 (the packet will be in queue) then all subsequent packets to the
6002 same remote host must also be put to the queue. Only after the
6003 queue has been purged is it safe again to force the packet
6006 o If you send all packets immediately then it safe to send
6007 any of subsequent packets through the queue, however, after
6008 the first packet is put to queue then any subsequent packets
6009 must also be put to the queue.
6011 Follow these rules and everything works fine.
6013 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6015 * Added new function silc_server_remove_clients_by_server to
6016 remove all client entries from ID list when the server connection
6017 is lost. In this case it is also important to invalidate all
6018 client entires as they hold the invalid server entry. This
6019 fixes fatal bug when server has lost connection and will reconnect
6022 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6024 * Made some sanity checks to silc_server_daemonise like to check
6025 whether the requested user and group actually exists.
6027 * Added sanity check to SKE's silc_ske_responder_finish to check
6028 that the public and private key actually is valid.
6030 * Invalidate the client's nickname when receiving Replace ID
6031 packet and the Client ID is being replaced. This means that the
6032 server will query the nickname if someone needs it (client)
6035 * Sort the ID Cache in client library when the ID Cache data
6036 has changed (needs sorting).
6038 * Do not allow for SILC client to create several connections to
6039 several servers. The client does not support windows right now
6040 and generating multiple connections causes weird behaviour.
6042 Irssi-silc client does support windows and can handle several
6043 connections without problems, see: www.irssi.org and SILC plugin.
6045 * Fixed some places where client was added to the IDList. The
6046 rule of thumb is following (in order to get everything right):
6047 If the client is directly connected local client then the
6048 `connection' argument must be set and `router' argument must be
6049 NULL to silc_idlist_add_client function. If the client is not
6050 directly connected client then the `router' argument must
6051 bet set and the `connection' argument must be NULL to the
6052 silc_idlist_add_client function.
6054 * The funtion silc_server_packet_send_local_channel actually did
6055 not check whether the client was locally connected or not. It
6056 does that now. Fixed a bug related to LEAVE command.
6058 * Fixed Remove Channel User payload parsing bug in server's
6059 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6061 * The server's silc_server_save_channel_key now checks also the
6062 global ID list for the channel as it might not be in the local
6063 list. Fixed a bug related to LEAVE command.
6065 * Is this the end of the [<unknown>] buglet that has been lurking
6066 around for a long time? A little for loop fix in server's
6067 silc_server_command_whois_parse that is used by both IDENTIFY
6068 and WHOIS command. At least, this was a clear bug and a cause
6069 of one type of [<unknown>] buglet.
6071 * WHOIS and IDENTIFY commands call the function
6072 silc_server_command_[whois/identify]_check function even if
6073 we are not router server.
6075 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Added --with-gmp configuration option. If set the GMP
6078 is always compiled in the SILC source tree. If not set then
6079 it is checked whether the system has the GMP3 installed. If
6080 it has then the GMP won't be compiled (the system's headers
6081 and library is used), if it doesn't have it then the GMP is
6082 compiled in the SILC source tree.
6084 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6086 * Changed RSA private exponent generation to what PKCS #1
6087 suggests. We try to find the smallest possible d by doing
6088 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6089 not security fix but optimization.
6091 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * Added new config entry [Identity] to fork the server and run
6094 it as specific user and group. A patch from Bostik.
6096 * Imported Dotconf configuration library into lib/dotconf.
6097 This will be used to create the SILC configuration files later.
6098 It will appear in the distsribution after this commit.
6100 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6102 * A big code auditing weekend happening. Auditing code for
6103 obvious mistakes, bugs and errors. Also, removing any code
6106 Removed files for being obsolete:
6108 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6109 inline in the file lib/silcutil/silcbuffer.h)
6111 o lib/silcutil/silcbufutil.c (the header has inline versions)
6113 Changed code to fix possible error conditions:
6115 o The buffer formatting routines now check that the destination
6116 buffer really has enough space to add the data. This applies for
6117 both buffer formatting and unformatting
6118 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6119 unformatting was changed to accomodate following rules:
6120 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6121 sent to the function while XXX_*STRING will not allocate or copy
6122 the data into the buffer. Instead it sets the pointer from the
6123 buffer into the pointer sent as argument (XXX_*STRING used to
6124 require that the pointer must be allocated already). This change
6125 makes this whole thing a bit more consistent and more optimized
6126 (note that the data returned in the unformatting with XXX_*STRING
6127 must not be freed now). The routines return now -1 on error.
6129 o Tried to find all code that use buffer_format and buffer_unformat
6130 and added return value checking to prevent formatting and
6131 especially unformatting errors and possible subsequent fatal
6134 o Changed ske->x and ske->KEY to mallocated pointers in
6135 lib/silcske/silcske.h. Fixed possible data and memory leak.
6137 o Added return value checking to all *_parse* functions. Fixed
6138 many memory leaks as well.
6140 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6141 so that buffer overflows would not happen. All code now also
6142 checks the return value as it can fail.
6144 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Added reconnection support to server if the normal server looses
6147 its connection to the router (for example if router is rebooted).
6148 The server performs normal reconnection strategy implemented
6149 to the server. Affected file silcd/server.c.
6151 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Added new packet type SILC_PACKET_SET_MODE that is used to
6154 distribute the information about changed modes (for clients,
6155 channels and clients channel modes) to all routers in the
6156 network. Updated the protocol specification accordingly.
6158 Added functions into silcd/packet_send.c and
6159 silcd/packet_receive.c: silc_server_send_set_mode,
6160 silc_server_set_mode.
6162 Added new files silcmode.[ch] into lib/silccore that implements
6163 the encoding and decoding of Set Mode Payload. Added new type
6164 SilcSetModePayload. Moved the definitions of different modes
6165 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6167 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6169 * Oops, a little mistake in server's connection authentication
6170 protocol. The protocol is not ended with FAILURE but with
6171 SUCCESS if the authentication is Ok. :) Affected file is
6174 * Implemented NICK_CHANGE notify handling in server in the file
6175 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6176 the local clients on the channel. After the changing nickname
6177 in router environment snhould work and the [<unknown>] nickname
6178 should appear no more.
6180 The silc_server_replace_id function that receives the Replace ID
6181 payload now sends the NICK_CHANGE notify type also in the file
6182 silcd/packet_receive.c
6184 * Changed WHOIS and IDENTIFY command to support the maximum amount
6185 of arguments defined in protocol specs (3328 arguments). This
6186 fixed a bug that caused problems when there were more than three
6189 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6191 * Added extra parameter, command identifier, to the
6192 silc_client_send_command so that explicit command identifier
6195 Changed that ID list routines uses specific command identifier
6196 when sending WHOIS/IDENTIFY requests to the server so that they
6197 can be identified when the reply comes back.
6199 Affected files lib/silcclient/command.[ch],
6200 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6202 * Added `sender' argument to silc_server_packet_send_to_channel
6203 to indicaet the sender who originally sent the packet to us
6204 that we are now re-sending. Ignored if NULL. Affected file
6205 silcd/packet_send.[ch].
6207 * Added some server statistics support in silcd/server_internal.h
6208 SilcServerStatistics structure and around the server code. Also
6209 send some nice statistics information when client is connecting
6212 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6214 * Fixed channel ID decoding in server's JOIN command reply in
6215 silcd/command_reply.c
6217 * Fixed braodcasting of replace ID payload to not to send it if
6218 we are standalone server in silcd/packet_receive.c.
6220 * Fixed all channel message sending routines to not to send
6221 packets to clients that has router set, since they are routed
6222 separately in the same function earlier. Affects file
6223 silcd/packet_send.c and all channel packet sending functions.
6225 * In USERS reply, res_argv[i] are not allocated, the table
6226 is allocated. Thus changed that free the table, not its
6229 * In server's whois_check and identify_check if the client is
6230 locally connected do not send any WHOIS commands - they are not
6233 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6235 * Fixed some minor bugs in client when sending WHOIS command. The
6236 arguments was in wrong order.
6238 * Removed statis function add_to_channel from server in
6239 silcd/command.c that was previously used with the joining but
6242 * Tested USERS command in router environment successfully with two
6243 routers, two servers and two clients.
6245 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6247 * Reorganized the USERS command and command reply in client library
6248 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6249 When the command is given by user we register a pending command
6250 callback that will reprocess the command after the reply has been
6251 received from the server. When reprocessing the packet we then
6252 display the information. Thus, the USERS information is displayed
6253 now in the command callback instead of in the command reply
6254 callback. The processing of the command is same as previously
6255 when server has sent the command reply in the JOINing process.
6257 * Added to USERS command in silcd/command_reply.c to join the client,
6258 we didn't use to know about, to the channel after we've created
6259 a client entry for it. Also, for clienet we did know already still
6260 check whether it is on the channel or not and add it if not.
6262 * Removed silc_server_command_join_notify as the function and its
6265 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Changed the client's pending command handling to the same as the
6268 server's pending command handling. It is also now possible to
6269 execute command reply functions from other command reply
6270 function as the function callbacks for commands and command
6271 replies are one and same. The pending commands are not static
6272 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6273 in client connection context. Thus, pending commands are server
6274 connection specific as it is convenient.
6276 Changed the function silc_client_command_pending and
6277 silc_client_command_pending_del and added new function
6278 silc_client_command_pending_check. Removed the
6279 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6282 * Added cmd_ident, current command identifier, to the client
6283 connection context in lib/silcclient/client.h to keep track on
6284 command identifiers used in command sending. Client's command reply
6285 function handling now supports the mandatory command identifiers.
6287 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6288 funtions in client to fully support pending command callbacks.
6290 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6291 as one of the arguments to the application in the command reply
6294 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6295 before first releasing SILC but came back. Now it is removed again
6296 and should come back nomore. The FORWARDED flag was used only
6297 by the JOINing procedure by forwarding the command packet to router.
6298 Now, the JOINing procedure has been changed to more generic (due
6299 to various router environment issues) and FORWARDED is not needed
6300 anymore for anything. The protocol specification is yet to be
6303 Now, removed silc_server_packet_forward from server and the flag
6304 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6306 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6308 * Renamed NAMES command to USERS command. The NAMES was named that
6309 due to historical reasons. Now it is renamed. Also, rewrote
6310 parts of the USERS command. The nickname list is not sent anymore
6311 by the server. Only Client ID and mode lists are sent in the USERS
6312 command. Changed this also to the protocol specification.
6314 The client now resolves the names and stuff after it receives
6315 the USERS list from the server when joining to the channel.
6317 * WHOIS and IDENTIFY commands has been changed to support multiple
6318 Client ID's per command. One can now search for multiple users
6319 in the network by sending only one WHOIS or IDENTIFY command.
6320 Changed the code and the protocol specifications.
6322 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6323 uses silc_server_command_whois_parse to parse the request. */
6325 * If normal server, do not parse the WHOIS and IDENTIFY requests
6326 before sending it to the router. Saves some time.
6328 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6330 * Fixed JOIN command on client library. Wrong number of arguments
6331 used to crash the client.
6333 * Added silc_server_channel_has_global function to check whether
6334 channel has global users or not.
6336 * Added silc_server_channel_has_local function to check whether channel
6337 has locally connected clients on the channel.
6339 * The silc_server_remove_from_one_channel now checks whether the
6340 channel has global users or not after given client was removed from
6341 the channel. It also checks whether the channel has local clients
6342 on the channel anymore. If it does not have then the channel entry
6343 is removed as it is not needed anymore.
6345 * The silc_server_notify now checks on JOIN notify whether the joining
6346 client is one of locally connected or global. If it is global then
6347 the channel has now global users on the channel and that is marked
6348 to the channel entry. Also, it now saves the global client to
6349 global list who is joining and JOINs it to the channel. This is
6350 for normal server, that is.
6352 Changed silc_server_send_notify_on_channel,
6353 silc_server_packet_relay_to_channel and
6354 silc_server_packet_send_to_channel check if we are normal server
6355 and client has router set (ie. global client) do not send the
6356 message to that client, as it is already routed to our router.
6358 * Implemented LEAVE notify type handling in silc_server_notify
6361 * Tested LEAVE command in router environment successfully. Tested
6362 with two routers, two servers and two clients.
6366 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6368 * Implemented SIGNOFF notify type handling in silc_server_notify
6371 * silc_server_remove_id now removes the client entry from all channels
6372 it has joined and thusly sends SIGNOFF notify type.
6374 * Rewrote the NAMES list generation in server by removing two excess
6375 loops. The lists are created now inside one loop.
6377 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6379 * silc_server_remove_channel_user checks now also global list
6380 for channel and client.
6382 * silc_server_new_channel_user checks now both local and global
6383 list for channel and client. Fixed a bug in client id decoding.
6384 Used to decode wrong buffer.
6386 * silc_server_channel_message checks now both local and global
6387 list for channel entry.
6389 * Tested channel joining (hence JOIN) in router environment
6390 successfully. Tested with two routers, two servers and two
6393 * Tested channel message sending in router environment successfully.
6395 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6397 * Added silc_server_save_channel_key into server.[ch] to save the
6398 received channel key in Channel Key payload processing. It is
6399 also used in JOIN command reply handling.
6401 Equivalent function silc_client_save_channel_key added into
6402 client.[ch] into client library.
6404 * Changed JOIN command reply to send information whether the channel
6405 was created or not (is existing already) and the channel key
6406 payload. Changed protocol specs accordingly.
6408 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6409 the request was sent by ID and not by nickname. Crashed on
6412 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6414 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6415 now correctly save the received data.
6417 * silc_server_free_sock_user_data now notifies routers in the
6418 network about entities leaving the network.
6420 At the same time implemented functions silc_server_remove_id
6421 and silc_server_send_remove_id to receive and send REMOVE_ID
6422 packets. The packet is used to notify routers in the network
6423 about leaving entities. The ID removed will become invalid in
6426 * Added function silc_idlist_del_server into server. Removes and
6427 free's server entry from ID list.
6429 * silc_server_private_message function now checks, if we are router,
6430 that the destination ID really is valid ID, naturally.
6432 * In router when NEW_ID packet is received (for new client) the
6433 hash of the Client ID is saved in the ID Cache but the
6434 client->nickname is set to NULL, instead of putting the hash
6437 IDENTIFY command now also checks that client->nickname must be
6438 valid. If it is not if will request the data from the server who
6439 owns the client. Added new function
6440 silc_server_command_identify_check.
6442 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6443 to set the command to already allocated Command Payload.
6445 * Tested private message sending in router environment with two
6446 routers, two servers and two clients. Fixed minor bugs and now
6449 * Fixed segfault from client's NAMES command. Used to crash if
6452 * Forwarded packets must not be routed even if it is not destined
6453 to the receiver. Changed server code comply with this.
6455 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6457 * Added `require_reverse_mapping' boolean value to ServerParams
6458 structure. If TRUE (not default) the server will require that
6459 the connecting host has fully qualified domain name.
6461 If the reverse mapping is not required and hostname could not be
6462 found the IP address is used as hostname.
6464 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6466 * Implemented version string checking to both client and server.
6467 The check is incomplete currently due to the abnormal version
6468 strings used in development version of SILC.
6470 * Changed all command functions in server to use the new
6473 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * Changed char *data to unsigned char *data in ID Cache system to
6476 support binary data as ID Cache data. Changed code to support
6477 binary data in lib/silccore/idcache.c.
6479 * Renamed silc_server_packet_relay_command_reply to
6480 silc_server_command_reply as it is normal packet receiving
6481 function. Rewrote the function to accept command replys for
6482 servers and not only for clients.
6484 * Mark remote router always as registered server if we are connecting
6485 to it. Otherwise, commands sent by the router to us are ignored.
6487 * All ID List find routines now returns the ID Cache Entry pointer
6488 as well if requested.
6490 * WHOIS command works now in router environment, tested with two
6491 routers, two servers and two clients.
6493 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6494 in router environment (as it is almost equivalent to WHOIS) but
6495 hasn't been tested thoroughly. Added new functions:
6497 silc_server_command_identify_parse
6498 silc_server_command_identify_send_reply
6499 silc_server_command_identify_from_client
6500 silc_server_command_identify_from_server
6502 * Disabled route cache adding because adding two different ID's with
6503 same IP replaces the old cache entry thus giving wrong route.
6504 The entry->router->connection is always the fastest route anyway
6505 so route cache may not be needed. Of course, new routes maybe
6506 established after receiving the ID when the entry->router->connection
6507 might not be anymore the most optimal.
6509 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6511 * Add route cache for received ID for fast routing.
6513 * Added silc_server_packet_route to route received packet on router
6514 that is not destined to us.
6516 * Renamed silc_server_get_route to silc_server_route_get.
6518 * Added id_string and id_string_len fields into SilcServer to
6519 include encoded ServerID for fast comparing without excess
6520 encoding of the ID's.
6522 * Cleaned up WHOIS command on server side. Added following static
6525 silc_server_command_whois_parse
6526 silc_server_command_whois_check
6527 silc_server_command_whois_send_reply
6528 silc_server_command_whois_from_client
6529 silc_server_command_whois_from_server
6531 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6532 arguments in command replies. All command functions should be
6533 updated to use this macro.
6535 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * Minor typo fixes on command reply handling on server.
6539 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6541 * Added silc_server_command_add_to_channel internal routine to add
6542 the client to the channel after router has created the channel and
6543 sent command reply to the server.
6545 * Added generic silc_server_send_command to send any command from
6548 * Use static buffer with ID rendering instead of duplicating data.
6550 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Fixed a channel user mode bug when joining to a channel server gave
6553 everybody channel founder rights, oops.
6555 * We mark ourselves as the router of the incoming server connection
6556 if we are router ourselves. This way we can check in some packet
6557 sending functions whether it is locally connected server. For
6558 incoming router connections we put NULL.
6560 * For router sending packets locally means now always sending the
6561 packet cell wide; to local clients and local servers. For normal
6562 server sending packet locally means sending it to only local
6565 * Fixed the JOIN command to really work in router environment. If the
6566 channel is created it is always created by the router. Router is
6567 also responsible of making the initial joining to the channel,
6568 sending JOIN notify to the sending server and distributing
6569 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6570 does not exist server doesn't do anything else but forward the
6571 command to the router which performs everything.
6573 * Added silc_server_send_channel_key function to send the Channel Key
6576 * Added silc_server_create_channel_key to create new channel key. The
6577 channel key is now re-generated everytime someone joins or leaves
6578 a channel, as protocol dictates. Note: channel->key_len is the
6581 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6584 packet_receive.[ch] to separate packet sending and receiving
6585 routines. The server.[ch] now includes everything else including
6586 actual packet processing (writing and reading data) and other
6589 Renamed silc_server_private_message_send_internal to
6590 silc_server_send_private_message. The routine is still though
6591 used only to relay private messages as server does not send
6592 private messages itself.
6594 Renamed silc_server_new_channel to silc_server_create_new_channel
6595 and added new function sicl_server_new_channel that handles the
6596 incoming New Channel packet. Added also new sending function
6597 silc_server_send_new_channel to send New Channel Payload.
6599 * Added new function silc_server_notify to process incoming notify
6600 packet to the server/router. Server may then relay the notify
6601 to clients if needed.
6603 * Added new function silc_server_new_channel_user to process incoming
6604 New Channel User packet. Router will redistribute the packet and
6605 send JOIN notify to its local clients and locally connected servers
6606 if needed. Normal server will send JOIN notify to its local client
6607 on same channel when received this packet. Added also corresponding
6608 sending function silc_server_send_new_channel_user to sent the
6611 * Added boolean route argument to send_notif_to_channel and
6612 packet_send_to_channel functions to attempt to route the packet
6613 if it is TRUE and send only locally if it is FALSE.
6615 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * silc_server_replace_id now broadcasts the received replace ID
6618 packet if it is not broadcast packet already. The router must
6619 broadcast to inform other routers about changed ID.
6621 * Added backpointer to server's router into SilcServer context in
6622 silcd/server_internal.h.
6624 * Fixed silc_server_packet_broadcast to send correct broadcast
6627 * The channel key is now distributed to the local client as soon
6628 as it is received from the router (in router environment) so that
6629 no other packet may be sent for the channel until client has
6632 * silc_server_remove_channel_user now broadcasts the received
6633 Remove Channel User packet if it is not broadcast packet already.
6634 The router must broadcast to inform other routers about removed
6637 * Added users field into SilcPacketContext that is a reference count
6638 of the context. One can increase the reference count by calling
6639 silc_packet_context_dup which is now changed to just increase the
6640 reference count instead of duplicating the data. The reference
6641 count is decresed by calling silc_packet_context_free that will
6642 free the data after the reference count hits zero.
6644 For now on the packet context and everything allocated into it
6645 (including the raw packet from network) must be freed by calling
6646 the new silc_packet_context_free function. Added also new function
6647 silc_packet_context_alloc that must be used now to allocate the
6648 context. This also means that if a routine is asynchronous from
6649 silc_[client/server]_packet_parse_type the packet context must
6650 be duplicated by calling silc_packet_context_dup. Otherwise it
6651 gets free'd after silc_[client/server]_packet_parse_type returns.
6652 Also, one must remember that if packet is duplicated then its
6653 reference count must be decresed by calling the free function as
6654 many times as it was duplicated.
6656 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6657 from both client and server.
6659 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6661 * Made joining to a channel working in router environment.
6663 * Cleaned up JOIN command on server side and create function
6664 silc_server_command_join_channel internal routine to make the
6667 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6669 * Changed silc_command_pending list to SilcDList. Also, added
6670 `ident' field to SilcServerCommandPending structure to identify
6671 the reply and to call correct callback.
6673 Added silc_server_command_pending_check function to replace the
6674 corresnponding macro. The silc_command_pending list is not
6677 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6678 to set identifier to previously allocated Command Payload. It
6679 is used to set identifier for command when resending Command
6682 * Added silc_command_payload_encode_payload to encode Command
6683 Payload buffer from SilcCommandPayload structure.
6685 * Added silc_argument_payload_encode_payload to encode Argument
6686 payload buffer from SilcArgumentPayload structure.
6688 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6690 * Changed WHOIS command to support router connection on server side.
6691 The whois request is always sent to router unless the server is
6692 standalone server. After server has received the reply from the
6693 router will it send the reply to the client.
6695 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6696 broadcast received broadcast packet. The function is used only
6697 by router. The broadcast packet is always sent to the router's
6700 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6701 render given ID to printable string, for log files for example.
6703 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6705 * Made basic router to router connections working. At least they
6706 can now connect to each other but nothing really works the way
6707 they are supposed - yet.
6709 * Added new initiator token to RouterConnection configuration
6710 file in silcd/serverconfig.[ch]. It is used to tell whether we
6711 are the initiator to the remote router or whether we'll expect
6712 the other end to connect.
6714 * Moved registering of listener task to silc_server_init, hence
6715 the server starts listenning as soon as it is run, even if it
6716 does not have connections to other routers. Let's see how well
6719 * Changed default connection retry timeouts for more suitable in
6722 * Removed cipher and such arguments from silc_idlist_add_client
6723 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6724 Added new function silc_idlist_add_data to add the keys and stuff
6727 * Added SilcIDListData structure and added it to SilcClientEntry
6728 and SilcServerEntry as their first field in the structure. This
6729 way we can explicitly cast the ID entries to the SilcIDListData
6730 structure and get common data for the entries. In past, we had
6731 to first check what type of connection it is and then cast it to
6732 correct ID entry type. Now, we can directly cast the opaque
6733 pointer to the SilcIDListData (no matter what ID entry it actually
6734 is) and get the data needed.
6736 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6738 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6739 in some circumstances even if threre were timeout tasks, though not
6740 IO tasks, but tasks anyway. Now fixed.
6742 * Defined SilcServerConnection structure to hold connection specific
6743 stuff about directly connected servers and routers. The definition
6744 is currently in silcd/server_internal.h. I thought about having
6745 a bit more important role fro this struct but for now it is used
6746 only when connecting to other server (or router actually).
6748 * Added connecting retry support in server when connecting to
6749 router(s). The retry feature implement exponential backoff
6750 algorithm. Also, added SilcServerParams structure to hold default
6751 parameters for server. For now, it include these retry settings
6752 and are hard coded. After server is moded to be as Silc Server
6753 Library this structure will be more important.
6755 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * Changed client librarys channel->clients table to SilcList and
6758 changed code accordingly.
6760 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6762 * Changed client's channel table to SilcList and changed code
6763 accordingly. Also changed SilcChannelClientEntry to include back-
6764 pointer to the channel so that client entry can use that structure
6765 as list as well and we have fast cross-reference to the channel.
6766 This change dramatically decreased the complexity of channel
6767 handling with client entry and vice versa (removed one extra
6768 loop when searching for channel entry from many functions).
6770 * Changed server->sim from table to SilcDList and changed code
6773 * NAMES command can now be used from user interface. It will show
6774 the user list on the channel, neatly.
6776 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6777 Code now saves realname of the user if it becomes available.
6779 * Renamed configure.in to configure.in.pre and made ./prepare
6780 script to automatically add correct version string to
6781 configure.in which it creates from configure.in.pre.
6783 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6785 * NAMES command reply now shows users mode with the nickname when
6788 * Moved silc_client_ch[u]mode[_char] functions from
6789 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6790 place sucks, they are utility functions and should be in some
6793 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6795 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6798 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Added TRQ (efficient deque and list library) into lib/trq. This is
6803 a very good list library that is currently used in the SILC. Defined
6804 SilcList API over the library because I didn't like the API very
6805 much. See lib/trq/silclist.h for the API and examples of how to
6806 use the API. Fixed various places in the code to use the new
6807 SilcList API. The SilcList is meant for lists that has a structure
6808 already defined as a list. It is not suitable to add just some
6809 context to the list (in TRQ, the context is the list actually).
6811 So, I defined SilcDList that can be used for the purpose where
6812 predefined list structure does not exit. This can be used as
6813 such list. Now some context just can be added to the SilcDList.
6814 Currently this list is not used in the SILC just yet, though there
6815 are a lot places where this can replace dynamically allocated
6816 tables and I will fix these places, later, to use SilcDList.
6817 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6818 and use TRQ internally).
6820 Also fixed some annoying warning messages that the original TRQ
6821 code generated. Also minor changes to TRQ's Makefile.in.
6823 * Added support for querying by Client ID to both WHOIS and
6824 IDENTIFY commands into server, as required by the protocol.
6826 * Removed method function pointers from SilcBuffer structure. They
6827 weren't used to anything and just increased the context size for
6828 no good reason. This change also made silc_buffer_alloc and
6829 silc_buffer_free functions inline functions.
6831 * Disabled command flooding detection support until it's fixed so
6832 that it accepts commands in but does not execute them more than once
6835 * Added silc_net_localhost(), to return local hostname, into
6836 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6837 that must be initialized before calling silc_client_init.
6839 * Added new function: silc_server_send_notify_on_channels to send
6840 notify messages to all channels client has joined. It is assured
6841 that the message is sent only once per client.
6843 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6844 lib/silcutil/silcutil.[ch] as silc_format function. The new
6845 function is generic and is used by server as well, not only by
6846 the logging routines.
6848 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6849 the provided version string was not acceptable. Added new function:
6850 silc_ske_check_version into lib/silcske/silcske.h. The function
6851 must be implemented by the application (client or server) and it
6852 does not reside in the SKE library. The function checks the version
6853 string remote end sent.
6855 * Added back pointers (to opaque context and to SilcSocketConnection)
6856 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6858 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6859 duplicate packet context structure.
6861 * Changed `notify' client operation to send same arguments as client
6862 receives from server except for ID's. ID's are mapped to correct
6863 ID entry and that is returned. Also, if channel entry is not sent
6864 by server but the notify is for channel the channel entry is sent
6865 to application (otherwise application doesn't know that it is for
6866 channel (library gets it from packet's Destination ID)).
6868 * Added silc_client_remove_from_channels into client library to
6869 remove a client from all channels it has joined to. Used when
6870 received SIGNOFF notify from server. Added also new function
6871 silc_client_replace_from_channels to replace old ID entry with
6872 new ID entry on all channels. Used when received NICK_CHANGE
6875 * Fixed ID Cache list handling in silc_idlist_get_client in
6876 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6877 to get (or query) client by ID.
6879 * Updated TODO list.
6881 * Added connection authentication status message defined by the
6882 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6883 support for these into the code in client and server side.
6885 * Added generic function silc_client_send_command to send any command
6886 with variable argument list. Application should use this function
6887 to send commands if the command functions provided by the library
6888 does not suite for the application's user interface needs.
6890 * Added new `failure' client operation. Application is notified about
6891 received failure packet if client is executing a protocol. In this
6892 case the protocol's execution has failed.
6894 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6895 is required by the protocol.
6897 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6898 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6901 * Added status flag to SilcSKE object to indicate realtime status
6902 of the SKE protocol.
6904 * Application receives now exactly same command reply arguments as
6905 the library receives from server. However, if ID is received the
6906 corresponding ID entry is returned to the application (eg. Client
6907 ID is mapped to correct SilcClientEntry entry and that is returned).
6908 Changed command_reply client operation due to this change.
6910 * Changed all ID's in commands and in command replys as ID Payloads.
6911 Change affected both client and server side codes.
6913 All ID's sent in SILC network (with execption of ID's in SILC
6914 Packet header) are sent in ID Payload to support variable length
6917 * Server now notifies nick changes and notifies all clients on
6918 the channels about the new nickname (about the new Client ID,
6921 * Implemented CMODE command to change channel modes. Supports all
6922 channel modes defined by the protocol specs except ban and invite
6923 lists. (Also, private channel key mode is supported but support for
6924 setting private channel key in client is missing, thus, this mode
6925 has no effect on client side (except that server requires that the
6926 client uses private channel key and normal channel traffic does not
6929 Also, invite mode works per se, but INVITE command does not work
6930 yet correctly, so you can set channel as invite only channel but
6931 inviting clients to the channel does not work (it is yet to be
6932 thought what's the best way to do it).
6934 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6935 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6936 Implemented CUMODE command to change user's mode on the channel.
6937 Supports all modes defined by the protocol specs.
6939 * Added NAMES command reply to return users modes on the channel.
6941 * Removed unnecessary and slow ciphers from lib/silccrypt.
6943 * Set SO_KEEPALIVE option to connection sockets by default.
6945 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6947 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6948 redefined the Notify Payload into protocol specs.
6950 * Added silc_id_payload_parse_id to get ID directly from raw
6953 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6956 accept searching by Client ID as well.
6958 * Added support for LEAVE and SIGNOFF notify types in client library.
6960 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6961 to parse ID Payload from raw data.
6963 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6965 * Added flags parameter into silc_ske_assemble_security_properties
6966 function in lib/silcske/silcske.[ch].
6968 * Changed notify client operation to fit better for notify messages
6969 sent by server. The notify payload received from server is now
6970 passed to the application (after parsing it to SilcNotifyPayload).
6971 It is application's responsibility to retrieve the arguments
6972 from the payload and show the message the way it wants. The message
6973 sent by server is implementation specific.
6975 * Changed public keys to comply with the protocol specification.
6976 Old public keys are not supported anymore and are not compatible.
6978 * Removed nickname from Channel Payload as the latest draft removed
6979 it. The client must resolve the nickname from the NAMES command
6980 reply received when it joined the channel.
6982 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6984 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6986 * Fixed some errors in protocol specification drafts.
6988 * Created lib/silccore/silcnotify.c to implement Notify Payload
6989 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6990 generic payloads described by protocol specifications. The file
6991 includes implementations for ID Payload and Argument Payload.
6993 * Changed Command Payload implementation to use the new Argument
6994 Payload. Changed command_xxxx_payload to command_payload_xxxx
6995 to comply with SILC coding conventions.
6997 * Added suppport for Argument Payload handling in Notify Payload
6998 implementation as protocol requires it. Added the new support
6999 into server and client lib as well.
7001 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Added support for multiple nicknames on same channel. [n] is
7004 added locally to the nickname if there are more than one same
7005 nicknames on the channel.
7007 * Server now sends all nicknames that matched WHOIS request.
7008 Client also shows the list received from server.
7010 * Added TOPIC command to client side. User can now set and show
7011 current topic on channel.
7013 * Added MOTD command to client and server. Also, server sends the
7014 motd when client connects to the server.
7016 * Changed version strings to comply ISO 8601.
7018 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7020 * Fixed protocol error handling in client library. It should now
7021 cope even if the SKE fails for some reason.
7023 * Made new protocol specification drafts for submitting to IETF.
7025 * Implemented TOPIC command to server in silcd/command.c.
7027 * Added two new notify types into lib/silccore/silcnotify.h:
7028 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7029 notify nickname change and topic setting/change on a channel.
7031 * API change of command_reply operation in client library. The
7032 application gets now the status type received from server as well.
7034 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7036 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7038 * Cras fixed and optimized the packet handling even further and
7039 it should work now. Minor change to the prototype of function
7040 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7042 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * Added new function into lib/silcutil/silcschedule.[ch]:
7045 silc_schedule_with_fd to select() a specified fd. The function
7046 returns after timeout expires or data arrives or goes. The
7047 function is used by packet routines to wait that all data is
7048 received from network.
7050 * Fixed data reading from network in lib/silccore/silcpacket.c.
7051 The code now assures that all data is read from the fd and then
7052 continues packet processing. This was a bug fix since the code
7053 used to drop some data in some circumstances.
7055 * Added new function into lib/silcclient/client.[ch]:
7056 silc_client_start_key_exchange to start key exchange after
7057 connection has been established to server. The code internally
7058 now uses this funtion but its main purpose was to provide it
7059 for applications that perform their own connecting. After
7060 application has created a connection it merely calls this
7061 function to start the key exchange between client and server.
7062 The library takes care of everything else after that.
7064 Updated also lib/silcclient/README to explain the usage of
7067 * Do not send to application information that connection has
7068 been established. Application gets notified it by connect
7071 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7073 * Applied cras's patch to add silc_schedule_one function. The
7074 function runs scheduler once and returns.
7076 * Fixed the scheduler after cras messed it up. The timeout
7077 handling works now as it's supposed to work.
7079 * Added into lib/silccore/ silcnotify.h to include notify
7080 message types support. Changed silc_server_send_notify*
7081 functions, in server.[ch], to support those new notify types.
7082 Added the support for the notify types into client library,
7083 as well. Added new notify client operation into ops.h in
7086 * Changed silc_server_packet_send_to_channel to send normal
7087 packets instead of just channel message packets. The function
7088 is now used to send the notify packets to channels. It is not
7089 used to send channel message packets anymore, as server never
7092 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7093 va_arg()s as it seems to require it nowadays. I guess, if SILC
7094 is compiled with older va_arg() the new code should work anyway.
7096 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * Splitted core library. Core library (lib/silccore) includes
7099 now only SILC protocol specific core (and common) components.
7100 Created new utility library (lib/silcutil) that includes more
7101 generic purpose stuff. The stuff for util library was taken
7102 from the old core library. This was minor and easy split.
7104 * Created SILC Client Library (lib/silcclient) that includes
7105 implementation of the SILC client without user interface. This
7106 was major move from silc/ directory. The code has been changed
7107 so that it is transparent towards the user interface. The
7108 silc/ directory includes now the same user interface as before
7109 and it uses the new client library. Read lib/silcclient/README.
7110 Basicly, the client library performs everything else related
7111 to SILC except user interface handling. Also, configuration
7112 files are considered to be part of user interface and library
7113 does not handle them.
7115 This change also changed a lot of structures, function naming etc.
7116 Most important change was that SilcClientWindow object was
7117 renamed to SilcClientConnection in the client library. Created
7118 also new file lib/silcclient/ops.h. Also added new files
7119 silc/local_command.[ch] and silc/client_ops.[ch].
7121 All these changes were made to make it easier for user interface
7122 designers to create what ever user interface for the SILC client
7125 It is also expected that the server will be moved to lib
7126 directory as well and SILC Server Library will be created;
7127 sometimes in the future.
7129 * Removed Local commands from lib/silccore/silccommand.h as
7130 they are application specific and new client library does not
7131 handle any of those anymore.
7133 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7134 old client implementation in silc/.
7136 * Added support for callback functions in SILC_LOG_* macros.
7137 Application can now set its own callbacks that will be called
7138 instead of using the default functions that will always print
7139 the debug messages to stderr (or stdout). Also, debugging can
7140 now be disabled by setting silc_debug to FALSE and re-enabled by
7141 setting it to TRUE. Note, that logging will still work even
7142 if debugging is disabled.
7144 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7145 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7146 silc_log_reset_debug_callbacks.
7148 * To enable debugging in silc client one must give now -d
7149 option on command line.
7151 * Changed silc_schedule_init to automatically allocate task queues
7152 if they are not allocated before calling it.
7154 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7156 * Added GMP 3.1 into math library.
7158 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7160 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7161 a channel in SILC network. The packet is used by servers and
7162 routers to notify other routers that user has left a channel.
7163 This little feature was missing until now. Added the feature
7164 to protocol specification as well.
7166 Added functions: silc_server_send_remove_channel_user and
7167 silc_server_remove_channel_user into server.[ch].
7169 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7170 lib/silccore/silcpacket.h. However, they are not implemented
7173 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7175 * Fixed joining to a channel and sending channel messages
7176 between server and router. The channel message sending should
7177 now work inside a cell.
7179 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7181 * Fixed the private message sending between server and router.
7182 The private message sending should now work inside a cell.
7184 * Added silc_server_replace_id into server.[ch] to replace
7185 existing ID in the SILC network.
7187 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7188 and silc_idlist_replace_server_id into idlist.[ch] in server.
7190 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7192 * Fixed the server to server connections. Server can again now
7193 connect to router. Router to router connections probably does
7196 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7198 * Added dynamic protocol registering support. Now protocols can
7199 registered and unregistered on the fly. Patch by cras.
7201 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7203 * Added lib/contrib directory to hold routines that some platforms
7204 don't have but are needed by SILC.
7206 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7207 into lin/contrib to provide getopt() and getopt_long() for
7208 those who don't have it.
7210 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7212 * Added AWAY command to client. When away message is set and
7213 client receives a private message packet the client automatically
7214 replies to the sender with the away message.
7216 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7217 bug seemed to be the cause of recent problems when compiling
7220 * Added version detection support to SKE protocol specification
7221 and added the new changes to the SKE implementation as well.
7222 There were other minor changes in the SKE protocol as well.
7224 Many changes in lib/silcske/silcske.[ch] and in
7225 lib/silcske/payload.[ch].
7227 * Added ^U functionality, clear input line. Patch from cras.
7229 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7231 * Mainly small bugfixes on core library. Fixed some debugging
7232 logging and buffer overflow in silclog.c.
7234 * Updated config.sub and config.guess on the distribution tree.
7236 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7238 * Added command lagging support in server. Client may execute
7239 commands now only once in two seconds.
7241 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7243 * Optimized packet reception. MAC computation and checking is now
7244 also more optimized. A lot previously duplicated code is now
7245 used as generic by both client and server.
7247 * Fixed key pair generation in clientutil.c
7249 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7251 * Added into lib/silccore/silcbufutil.[ch] new function;
7252 silc_buffer_realloc.
7254 * Moved generic packet sending/encryption functions to
7255 lib/silccore/silcpacket.[ch] from client and server. Some
7256 rewriting of the functions.
7258 * Moved all generic packet reception/decryption functions to
7259 lib/silccore/silcpacket.[ch] from client and server. The
7260 packet processing is now much cleaner in both client and server.
7261 These were major changes in both client and server.
7263 * Created many common functions in server to do packet sending.
7264 Previously code were duplicated a lot, this has been removed
7267 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7269 * Rewrote major parts of the ID cache system. Don't know
7270 whether it is better now or not but at least the API is more
7273 * Major rewrite on ID cache stuff on client because of the ID
7274 cache API changes. Added idlist.c to client.
7276 * Also major rewrite on ID cache stuff on server as well.
7277 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7278 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7279 in hand, instead they are all put into the ID cache system now.
7280 All server_idlist_* routines uses ID cache now instead of
7281 traversing its own lists (those lists does not exist anymore).
7282 SilcIDList though still exists. Also, SilcXXXEntry's are
7285 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7287 * Finally made the SKE implementation compliant to the protocol
7288 specification. All mp integers are now binary encoded as
7289 opposed being HEX encoded.
7291 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7294 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7295 functions: silc_[encode/decode]_pem. Also added function
7296 silc_encode_pem_file to PEM encode with newlines ('\n') for
7299 * SILC public keys are now encoded either PEM or binary. Same
7300 option is for private keys as well. By default private keys
7301 are binary encoded and public keys PEM encoded. Silly HEX
7302 encoding were removed.
7304 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7305 function to create fingerprints.
7307 * Fixed a bug in SHA1; does not change the original data anymore.
7309 * Partly implemented INFO command on client and server side.
7310 Fixed CLEAR command. Changes to SERVER command; show current
7311 server(s) when giving command without arguments. Added
7312 VERSION command to client.
7314 * Added check to server that unregistered connections cannot
7315 execute commands (unless it is specificly allowed).
7317 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7319 * Fixed screen refresh.
7321 * Fixed channel joining bug from client. On some circumstances
7322 client tried to join to a channel it had already joined.
7324 * Added public key verification process into client's protocol.c.
7325 The client now verifies the public key from user and saves
7326 it into ~./silc/serverkeys/ directory.
7328 Added into: clientutil.[ch]: silc_client_verify_server_key.
7330 * Changed SKE protocol's silc_ske_initiator_finish function
7331 to accept callback function that verifies the received public
7332 key. Removed old silc_ske_verify_public_key function.
7334 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7336 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7337 silc_pkcs_private_key[_data]_set.
7339 * Made the password and public authentication more cleaner in
7340 server's protocol.c.
7342 * Removed historic and obsolete protocol `channel_auth' from
7343 both client and server.
7345 * Removed wrong way of sending command status messages from
7346 server to client in server's command.c. The old way violated
7347 protocol specification.
7349 Changes to silccore/silccommand.[ch]: removed
7350 silc_command_encode_status_payload -> not needed anymore,
7351 changed silc_command_encode_payload_va to accept extra
7352 argument on variable argument list. The argument type must
7353 now be provided to the function. Also, added new function:
7354 silc_command_encode_reply_payload_va which is same as
7355 normal command_encode_payload_va except command status type
7356 is provided as extra argument.
7358 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7360 * Added ~./silc directory handling. The directory includes the
7361 public and private keys for the client.
7363 Added silc_client_check_silc_dir, silc_client_create_identifier
7364 and silc_client_load_keys.
7366 * Implemented SILC protocol compliant public key. Added public
7367 and private key saving to and loading from files.
7369 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7370 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7371 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7372 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7373 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7375 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7376 silc_pkcs_load_[public/private]_key.
7378 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7380 * Added silc_server_get_route (route.[ch]) to get connection
7381 data for the fastest route for given ID.
7383 * Implemented INVITE command on client and server. The command
7384 were re-defined in the SILC Protocol Specification and the
7385 implementation now complies with the specification.
7387 * Implemented PING command on client and server.
7389 * Implemented NAMES command on client and server. The server side
7390 supports currently only normal server not router server yet.
7391 Some changes to NAMES definition in SILC protocol specification.
7393 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7395 * Implemented LEAVE command on client and server.
7397 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7398 again. This change was made to the protocol as well. Server
7399 should not violate the protocol specification anymore.
7401 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7403 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7404 was tested. SOCKS4 was not but should work anyway.
