1 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Check for unauthenticated client and server in the
4 silc_server_new_client and silc_server_new_server functions.
5 Affected file silcd/packet_receive.c.
7 * Added function silc_string_is_ascii to check whether given
8 string is 7-bit ASCII string. Affected files are
9 lib/silcutil/silcutil.[ch].
11 * Added function silc_id_is_valid_server_id into the
12 silcd/serverid.c and added checking for valid Server ID's in
13 silc_server_new_server. The Server ID must always be based
14 on the server's public IP address.
16 * Added logging of DISCONNECT packet message in the server.
17 Affected file silcd/server.c.
19 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
21 * Changed all library interfaces that use Global RNG to also
22 accept SilcRng as argument. Affected files are
23 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
24 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
25 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
26 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
29 * Added function silc_pkcs_generate_key to the
30 lib/silccrypt/silcpkcs.[ch] for applications so that they
31 don't need to do pkcs->pkcs->init calls anymore.
33 * Remove SilcSocketConnection from the SFTP API since it really
34 wasn't needed there. The application has the information
35 saved in its contexts anyway and the SFTP layer doesn't need
36 know about it. Affected files lib/silcsft/silcsftp.h and
37 lib/silcsftp/sftp_[server/client].c.
39 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
40 The SilcSimContext is not SilcSim.
42 * Fixed possible buffer overflows in silc_id_render in the
43 lib/silcutil/silcutil.c.
45 * On EPOC the global crypto module lists are not used at all
46 in the crypto library. Added support for using the constant
47 algorithm list on EPOC. Affected files are
48 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
51 * Fixed the handling of third parameter of KICKED notify, since
52 it was mistakenly updated to SILC Protocol 1.0 even though it
53 is to be included in 1.1. Since it is not in 1.0 it is not
54 mandatory, and this fix now handles it only if it is provided,
55 and it is not error if it is not provided. Affected file
56 lib/silcclient/client_notify.c.
58 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
60 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
61 client. Affected file irssi/src/silc/core/client_ops.c.

68 sending any messages. Fixes a crash, but doesn't fix some
69 other underlaying bug that is lurking there. Affected
70 file silcd/packet_send.c.
72 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
74 * $usermode, $cumode and $cumode_space expandos shouldn't do
75 anything with non-SILC server records. Affected file
76 irssi/src/silc/core/silc-expandos.c
78 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
80 * Fixed the silc_net_check_[host/local]_by_sock to support
81 IPv6 bound sockets as well. Now they can return IPv6 addresses
82 as well. Affected file lib/silcutil/silcnet.c.
84 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
85 Affected lib/silcutil/unix/silcunixnet.c.
87 * Fixed ID rendering (at least on some platforms, not NetBSD)
88 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
90 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
92 * Added silc_hash_public_key and silc_hash_public_key_compare
93 functions to be used with SilcHashTable. They can be used to
94 hash public keys and compare public keys in hash table. Affected
95 file lib/silcutil/silcutil.[ch].
97 * Added support for specifying multiple public keys for Client
98 connection section in server configuration file. This makes it
99 possible to accept multiple public keys from same host, or to
100 make a section that accepts any incoming host, and have the
101 accepted public keys listed in the section.
103 Added functions silc_sever_[find/get]_public_key, added the
104 support for this actually to all connection sections but only
105 the Client section is currently allowed to specify multiple
108 Affected files are silcd/server.c, server_internal.h,
109 command.c, protocol.c, server_util.[ch], packet_receive.c.
111 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

118 to stderr with the debug output.
120 Made silc_log_reset_all() flushing all channels before returning.
121 Also fixed some documentation typos.
123 Affected files are lib/silcutil/silclog.[ch].
125 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
127 * Fixed the server to check correctly the amount of connections
128 from single host, by checking also the type of the connection.
129 Fixed also the comparison of number of connections and number
130 of allowed connections. Affected files are silcd/server.c,
133 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
135 * Fixed the USERS command reply to save the user's mode on the
136 channel as well. Fixed JOIN command reply to check whether a
137 client is on channel already and not join it twice. Affected
138 file lib/silcclient/command_reply.c.
140 * Added new file silc-expandos.c into irssi/silc/core/ to return
141 various stuff for various signal for the statusbar etc. updating.
142 Now Irssi SILC client prints channel user modes etc. on the
145 * The user mode (like server/router operator changes) is now shown
146 on the Irssi SILC client's statusbar. The affected files are
147 irssi/src/silc/core/client_ops.c, silc-expandos.c.
149 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>

183 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
185 * Changed all integer type names:
186 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
187 to avoid collisions with other libraries using same type names
190 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
192 * Added `prefer_ipv6' argument to the functions
193 silc_net_gethostbyname[_async]. If it is TRUE it will return
194 IPv6 address over IPv4. If FALSE IPv4 address is returned
195 even if IPv6 address was found. Affected files
196 lib/silcutil/silcnet.[ch].
198 * Added support silc_net_create_connection[_async] to fallback
199 to IPv4 address if IPv6 address could not be used (like if

212 application does not need to define them. Affected file
213 includes/silcincludes.h.
215 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
216 old name went against naming convention. Applications now
217 include "silcclient.h" instead of "clientlibincludes.h".
218 Removed includes/clientlibincludes.h, it is redundant now.
220 * Renamed includes/version.h to silcversion.h.
222 * Added really preliminary support for OS/2 into the util
223 library. Only thread & mutex API is implemented, others
224 are still to be implemented. Created the lib/silcutil/os2/
225 directory. Created also file includes/silcos2.h.
227 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
229 * Added preliminary BeOS support into the util library.
230 Created lib/silcutil/beos/, and implemented all the needed

236 * Added proper initializations to silc's irssi code, so it's
237 now possible to load it as module. Affected files
238 irssi/src/silc/core/silc-core.c,
239 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

256 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
258 * Added `user_count' to the SilcChannelEntry which now tells the
259 number of users on the channel. The user count is now saved
260 in normal server of global channels as well. Affected files
261 silcd/server.c, idlist.h, packet_receive.c and command.c.
263 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

274 client_entry->channels hash table everytime nick is changed.
275 Affected file lib/silcclient/client.c.
277 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
279 * ROBOdoc documented the lib/silcske/silcske.h, and improved
280 the SKE interface a bit.
282 * Fixed padding problem in PKCS#1. The padding was not actually
283 random since the random number generator was used incorrectly.
284 This security bug affects only when encrypting with PKCS#1, and
285 it is not currently used at all in SILC. SILC only use signing
286 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
288 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
290 * Rewrote the notify handling in Irssi SILC client to not call

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

328 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
330 * Fixes to the silcd config template. Affected file is
331 doc/example_silcd.conf.in.
333 * Removed type casts from silc_calloc(), conforming to the
334 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
336 * Removed param_name member from client, server, and router
337 section structs, now identifying the param directly.
339 Added CONFIG_FREE_AUTH macro in config file parsing.
341 Affected files are silcd/serverconfig.[ch].
343 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
345 * Fixed command line parameter handling. All SILC initialization
346 is now done in silc_core_init() which also fixes autoconnecting
349 Affected files irssi/src/silc/core/silc-core.c,
350 irssi/src/fe-text/silc.c.
352 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
354 * Added new configuration options and blocks:
355 keepalive_secs, reconnect_count, reconnect_interval,
356 reconnect_interval_max, reconnect_keep_trying and
357 require_reverser_lookup. Added ConnectionParam block, and
358 implemented the connection parameters when connecting as
359 initiator and when accepting connections as responder.
361 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
362 whether given configuration value has been given already.
364 Affected files silcd/serverconfig.[c], server.[c].
366 * Splitted the doc/example_silcd.conf.in. Separated the crypto
367 algorithm parts and created new file silcalgs.conf, that
368 is now included from the example_silcd.conf.in.
370 * Optimized the silc_server_connect_to_router_second to take
371 the connection configuration object from the SilcServerConnection
372 object instead of finding it during the connecting phase.
373 Added the configuration object to SilcServerConnection struct.
374 Affected files silcd/server_internal.h, server.c.
376 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
378 * Add the client on channel after it was resolved at the
379 channel message receiving, and it was not already on the
380 channel. Affected file lib/silcclient/client_channel.c.
382 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
384 * Fixed the public key authentication to allocate always the
385 destination signature buffer instead of using static buffer.
386 Affected file silcd/protocol.c.
388 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
390 * Unified the serverconfig.[ch]'s helper function interface.
391 Affected file silcd/serverconfig.[ch].
393 * Removed doc/example_silc.conf.in since it is redundant.
394 The make install will now install irssi/silc.conf file.
396 * Added new Passphrase and Publickey authentication methods to
397 config file, allowing both public key and passphrase based
398 authentication to be set at the same time.
400 Added `prefer_passphrase_auth' setting in config file which
401 can be used to set to prefer passwd auth if both passwd and
402 public key is set. If not set, public key is preferred.
403 This has effect only when being initiator (responder will try
406 Added support for authentication with passphrase and public key
407 at the same time. The passphrase is tried first always since
408 it is faster to check.
410 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
412 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
414 * Merged the new SILC Config library, with the server parsing

456 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
458 * Fixed the file transfer's key agreement payload to include
459 zero port also if the hostname is NULL because it could not
462 Call file transfer monitor callback now also if error occurs
463 during key agreement protocol.
465 Changed the silc_client_file_send interface to return the
466 SilcClientFileError instead of session id. The session ID
467 is returned into pointer provided as argument.
469 Check that the file exists locally before sending the
470 file transfer request at all.
472 Affected file lib/silcclient/client_ftp.c, silcapi.h.
474 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
475 error than can occur while key agreement protocol. Affected
476 file lib/silcclient/silcapi.h.

479 is changed and +k mode is set in the channel. Affected file
480 irssi/src/silc/core/silc-channels.c.
482 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
483 SILC_LOG_WARNING to give out Warning and not Error. Affected
484 file lib/silcutil/silclog.c.
486 * Fixed the channel message payload decryption in the function
487 silc_channel_message_payload_decrypt to not modify the original
488 buffer before it is verified that the message decrypted
489 correctly. Otherwise, next time it is called with correct
490 channel key it won't encrypt since the payload is corrupted.
491 Affected file lib/silccore/silcchannel.c.
493 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

505 * Fixed a bug in hash table internal routine for traversing
506 the table with foreach callback. The current entry may
507 become invalid in the callback but it was referenced after
508 the callback returned.
510 Do not allow auto rehashing of hash table during the
511 silc_hash_table_foreach operation, for same reasons as it is
512 not allowed for SilcHashTableList. Affected files are
513 lib/silcutil/silchashtable.[ch].
515 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
517 * Defined DLLAPI into silcincludes.h and silcwin32.h for

521 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
523 * Fixed private message handling. It used some old code that
524 caused the client to crash. Affecte file is
525 lib/silcclient/client_prvmsg.c.
527 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
529 * Added function silc_client_add_channel,
530 silc_client_replace_channel_id, and removed functions
531 silc_client_new_channel_id and silc_idlist_get_channel_by_id
534 * Added cross reference of the joined channels to the
535 SilcClientEntry, and changed the SilcChannelEntry's
536 users list to SilcHashTable. The affected files are
537 lib/silcclient/idlist.[ch].
539 * Fixed a bug in hash table tarversing. While the hash table
540 is traversed with SilcHashTableList the table must not be
541 rehashed. It is now guaranteed that auto rehashable tables
542 are not rehashed while tarversing the list. Also defined that
543 silc_hash_table_rehash must not be called while tarversing
544 the table. Added function silc_hash_table_list_reset that must
545 be called after the tarversing is over. The affected files are
546 lib/silcutil/silchashtable.[ch].
548 * Changed all hash table traversing to call the new
549 silc_hash_table_list_reset in server and in client library.
551 * Added function silc_client_on_channel to return the
552 SilcChannelUser entry if the specified client entry is joined
553 on the specified channel. This is exported to application as
554 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
556 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
558 * Fixed founder regaining problem with JOIN command on normal
559 server. The notify for mode change must be sent always and
560 not only if !cmd->pending. Affected file silcd/command.c.
562 * Fixed the WHOWAS command's reply sending to support the
563 lists correctly. Affected file silcd/command.c.
565 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
567 * When sending JOIN command to router for processing the
568 sender's old command identifier was not saved back to the
569 sender's command context, fixed now. The affected file is
572 * Create the key in JOIN command of the router did not return
573 the channel key, added check for this. Affected file is
576 * Fixed a channel ID update bug in JOIN command reply. Do
577 not directly upgrade the ID but call the function
578 silc_idlist_replace_channel_id if the ID was changed.
579 Affected file silcd/command_reply.c.
581 * Fixed memory leaks from command calling if it would fail.
582 Affected file silcd/command.c.
584 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
586 * Applied patches from cras:
588 Memory leak fixes around libaries, irssi window resize fix,
589 new silclist.h and silcdlist.h, all extern inline changed to
592 * Removed dotconf from lib/dotconf, not needed anymore.
594 * Removed TRQ from lib/trq, not needed anymore.
596 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
597 with server connections. Later this will be configurable
598 in config file after new config file is done. Affected file
601 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
603 * Fixed a crash in server related to channel announcements.
604 Affected file silcd/server.c.
606 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
608 * Fixed memory leaks in silc_server_create_new_channel*
609 functions. Affected file silcd/server.c.
611 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
612 which ID was changed. This way the router will send the
613 user list for the channel again, and server won't be in
614 desync in some rare circumstances. Affected file is
615 silcd/packet_receive.c.
617 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
619 * Check for NULL socket pointer in the function
620 silc_server_packet_send_to_channel_real. Affected file
623 * Fixed the BAN notify handling to correctly remove ban
624 list. Affected file silcd/packet_receive.c.
626 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
628 * Fixed some header addition to Toolkit distribution in
629 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
631 * Added lib/silcclient/client_ops_example.h as an template
632 file for application programmers to quickly start using
633 the SilcClientOperation functions in their application.
634 Updated the lib/silcclient/README as well to tell about this
635 nice file made available.
637 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
639 * Call silc_server_remove_from_channels when removing client
640 entry when NO_SUCH_CLIENT_ID was received. Affected file
641 is silcd/command_reply.c.
643 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
645 * Added server & router operator statistics updating. Affected
646 file silcd/packet_receive.c and silcd/command.c.
648 * Fixed the SERVER_SIGNOFF notify handling on normal server
649 not to save the history information for clients. Same was
650 fixed earlier in remove_clients_by_server function, but not
651 here. Affected file silcd/packet_receive.c.
653 * Raised the default connection-retry count from 4 to 7 in
654 server. Affected file silcd/server.h.
656 * Cancel any possible reconnect timeouts when we start the
657 key exchange. Affected file silcd/server.c.
659 * Do not reconnect on connection failure when SCONNECT was
660 given. Affected files silcd/server.[ch].
662 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
664 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
666 * Fixed the NICK command to always give the unformatted
667 nickname to the one giving the NICK command. If unformatted
668 nickname is cached already it will be formatted and the
669 local entry will always get the unformatted nickname.
670 Affected file lib/silcclient/idlist.c.
672 * Fixed some double frees from client library commands.
673 Affected file is lib/silcclient/command.c.
675 * Fixed CUMODE command in server to assure that no one can
676 change founder's mode than the founder itself, there was a
677 little bug. Affected file silcd/command.c.
679 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
681 * Removed the SilcClientCommandDestructor from the client
682 libary, it is not needed anymore. Affected files are
683 lib/silcclient/silcapi.h, command[_reply].[ch],
684 client_notify, idlist.c.
686 * Fixed GETKEY command to first resolve client, and then
687 resolve the server only if the client was not found, instead
688 of resolving both at the same time. Affected file is
689 lib/silcclient/command.c.
691 * Added silc_client_start_key_exchange_cb and lookup the
692 remote hostname and IP address before starting the key
693 exchange with server. The affected file is
694 lib/silcclient/client.c.
696 * The server's public key is now saved using the IP address
697 of the server and not the servername for the filename.
698 The hostname public key filename is checked as an fall back
699 method if the IP address based filename is not found.
701 Fixed the GETKEY command to save the fetched server key
704 Print the remote server's hostname now when new key is
705 received during connection process. Affected file is
706 irssi/src/silc/core/client_ops.c.
708 * Return always our own public key to the client if it asks
709 for it with GETKEY command. Affected file silcd/command.c.
711 * Removed the use_auto_addr variable from default config
712 file since it was in wrong section. Affected file is
715 * Fixed TOPIC_CHANGE notification to not route it when it
716 was sent using silc_server_send_notify_to_channel function.
717 Affected file silcd/command.c.
719 * Fixed silc_server_send_notify_kicked to send the kicker's
720 Client ID also, it was missing. Affected files are
721 silcd/command.c, silcd/packet_send.[ch].
723 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
725 * Do not save client history information in SERVER_SIGNOFF.
726 Fixes the bug in normal server that it does not detect
727 the client becoming valid after the server becomes back
728 online. Affected file silcd/server_util.c.
730 * Added `sock_error' field into the SilcSocketConnection
731 context. When error occurs during socket operation (read
732 or write) the error is saved. Added also new function
733 silc_socket_get_error to return human readable socket error
734 message. Affected files are lib/silcutil/silcsockconn.[ch],
735 lib/silcutil/unix/silcunixsockconn.c, and
736 lib/silcutil/win32/silcwin32sockconn.c.
738 * The server now prints the socket error message in the
739 signoff for client. Affected file silcd/server.c.
741 * Fixed the `created' channel information sending from router
742 to server in JOIN command. Checks now whether the channel
743 really was created or not and set it according that.
745 Fixed the JOIN command to use the client entry's current
746 ID during the joining procedure instead of the one it sent
747 in the command (it is checked though), since it can change
748 between the packet processing and command processing, and
749 would just case unnecessary pain in the client end. Affected
750 file silcd/command.c.
752 * Fixed a channel key payload sending to use correct channel
753 ID when the server was forced to change the channel's ID by
754 router. Router sent the key payload with the old Channel ID.
755 Affected file silcd/packet_receive.c.
757 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
759 * Call silc_server_save_channel_key only if the key payload
760 was provided in the JOIN command's command reply. Affected
761 file silcd/command_reply.c.
763 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
765 * Fixed silc_mp_sizeinbase to return the value correctly with
766 MPI. Affected file lib/silcmath/mp_mpi.c.
768 * Fixed the stop_server signal to correctly stop the scheduler
769 and gracefully stop the server when SIGTERM or SIGINT signals
770 are received. Affected file silcd/silcd.c.
772 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
774 * Simple handling of TERM and HUP signals. Also added some log
775 flushing call around. Affected file is
778 * Fixed small bugs in silclog.c. Now buffering output will take
779 effect after 10 seconds since startup: This will ensure that
780 no important startup messages are lost. Also output redirection
781 will preserve original format ([Date] [Type] message).
782 Affected file is lib/silcutil/silclog.c.
784 * Added two options to the config file, in the logging section:
785 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
786 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
788 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
790 * Do not print the warning about log files not being initialized
791 more than once to avoid excess logging. Affected file is
792 lib/silcutil/silclog.c.
794 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
795 the SIM copying in make install in Makefile.am.pre.
797 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
799 * Rewritten silclog APIs. Globally interesting changes follows:
800 silc_log_set_files() changed to silc_log_set_file().
801 silc_log_set_callbacks() changed to silc_log_set_callback().
802 ROBOdoc documented silclog header file.
803 SilcLogCb now returns bool to wether inihibit the default
804 handler or not (to keep the old behaviour return always TRUE).
805 The new APIs should also fix the problem of the
806 silcd_error.log file that was written in the current directory.
809 Log files streams will remain opened after silc_log_set_file()
810 call, means less CPU usage notably on high traffic servers.
811 File streams are now full buffered, and flushed to the disk
812 every 5 minutes, lesses HD activity and CPU usage.
813 Messages can be redirected, allowing admins to configure
814 one single logfile for all server messages.
815 the silc_log_quick global variable to activate fast-logging.
816 Affected files lib/silcutil/silclog.[ch]
818 * Changed some code to conform new silclog APIs. Affected
819 files are doc/example_silcd.conf.in, silcd/server.c
820 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
823 * Fixed a memory leak that could occur in some situations.
824 Affected file silcd/serverconfig.c.
826 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
828 * Added the silc_client_del_client to remove the client from
829 all channels as well. Affected file lib/silcclient/idlist.c.
831 * Fixed the client library to correctly remove the client
832 from all channels when the client entry is being destroyed.
833 Affected file lib/silcclient/client_notify.c, command.c.
835 * Added auto-nicking support to the client library. If the
836 applicatio now sets client->nickname it will be sent to the
837 server after connecting by the library. This way for example
838 SILCNICK (or IRCNICK) environment variables will have effect
839 and always change the nickname automatically to whatever
840 it is wanted. Affected file lib/silcclient/client.[ch].
842 * Renamed silc_server_command_bad_chars to the
843 silc_server_name_bad_chars and moved it to the
844 silcd/server_util.[ch]. Added also new function
845 silc_server_name_modify_bad to return nickname that
846 includes bad characters as new nickname without those
847 bad characters. This check and modify is now used in
848 silc_server_new_client when the username is initially set
849 as nickname, so it must be checked to be valid nickname.
850 Affected file silcd/packet_receive.c.
852 * The nickname length is now taken from the packet for real
853 and not trusted to strlen() since it clearly can return
854 wrong length for nickname including bad characters. This
855 also applies to channel names. Affected file silcd/command.c.
857 * Removed the lib/silcsilm/modules directory. Modules are now
858 compiled into the lib/silcsim. Fixed the copying of the
859 modules to follow symbolic links in Makefile.am.pre.
861 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
863 * Fixed silc_string_regexify list creation. Fixes bugs with
864 BAN and INVITE commands in server. The affected file is
865 lib/silcutil/unix/silcunixutil.c.
867 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
869 * Removed the command destructor entirely from the server's
870 command and command reply routines. It is not needed, and
871 its usage was buggy and caused crashes. Affected files are
872 silcd/command[_reply].[ch].
874 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
876 * Cancel protocol and NULL sock->protocol if timeout
877 occurred during protocol. Affected file silcd/server.c.
879 * Cancel protocol timeouts always before calling the final
880 callback, to assure that after final callback is called
881 no other state will be called for the protocol anymore.
882 Affected file silcd/protocol.c.
884 * Print error log if incoming connection configuration could
885 not be found. Affected file silcd/server.c.
887 * Fixed JOIN command to correctly save the founder mode
888 to the client on normal SILC server, when the channel
889 was created by the router. Affected file silcd/command.c.
891 * Fixed LIST command (hopefully) to send correct reply
892 packets. Affected file silcd/command.c.
894 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
896 * The silc_packet_receive_process now returns FALSE if the
897 read data was invalid packet, and TRUE if it was ok.
899 The server now checks that if unauthenticated connection
900 sends data and its processing fails the server will close
901 the connection since it could be a malicious flooder.
903 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
905 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Make sure the warning about error opening a log file is
908 printed only once and not everytime it fails (produces
909 too much useless log). Affected file lib/silcutil/silclog.c.
911 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
913 * Made the silc_server_daemonise() function more readable.
914 Affected file silcd/server.c.
916 * Pid file is now optional, the user may comment it out from
917 the config file. Removed define SILC_SERVER_PID_FILE, we
918 don't need a default any longer. Affected file
919 configure.in.pre, lib/Makefile.am.pre.
921 * Make some use of the pid file. The server now dies at startup
922 if it detects a valid pid file on his path. The server would
923 die anyway in this circumstance, because of the bind() failure.
924 Affected file silcd/silcd.c.
926 * No longer compiling lib/dotconf.
928 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
930 * Fixed JOIN command parsing not to crash. Affected file
931 lib/silcclient/command.c.
933 * Fied the NICK_CHANGE notify to add the new client entry
934 even it is resolved. This removes an <[unknown]> nick
935 thingy bug in the client. Affected file is
936 lib/silcclient/client_notify.c.
938 * Do not try to allocate 0 bytes (efence does not like it)
939 in lib/silccore/silccomand.c when encoding payload.
941 * Do not take IRCNICK as nickname in Irssi SILC client since
942 it is not possible to set nickname before hand connecting
943 the server (TODO has an entry about adding auto-nicking
946 * Changed the silc_server_command_pending to check whether
947 there already exists an pending entry with the specified
948 command, command identifier and pending callback. This is
949 to fix IDENTIFY and WHOIS related crashes that may register
950 multiple pending commands with same identifier. Affected
951 file silcd/command.c.
953 * Fixed the server to reconnect to the router even if it
954 was already reconnecting and EOF was received. This to
955 fix a possibility that the server wouldn't ever try to
956 auto-reconnect to the router. Affected file silcd/server.c.
958 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
960 * Fixed the server's password authentication to use the
961 length of the locally saved password, and not the one
962 sent in the packet. Affected file silcd/protocol.c.
964 * Fixed same password authentication problem in the
965 Authentication Payload handling routines in
966 lib/silccore/silcauth.c.
968 * Yet another password authentication problem fixed with
969 channel password handling in silcd/command.c.
971 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
973 * If first character of string in silc_parse_userfqdn is '@'
974 then do not parse it. Affected file is
975 lib/silcutil/silcutil.c.
977 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
979 * Fixed minor bug in IDENTIFY command reply sending, which
980 caused various weird problems during JOIN when it was
981 resolving names for users. Affected file silcd/command.c.
983 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
985 * Fixed the IDENTIFY command reply sending to chech better valid
986 clients. It was possible to send incomplete list of replies.
987 Affected file silcd/command.c.
989 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
991 * Added silc_client_command[s]_[un]register functions now to
992 dynamically register the commands in client library. Removed
993 the static table of commands. This allows the client library
994 to call commands without causing the application to know about
995 what commands library has called.
997 Removed the INFO command reply kludge to detect when the command
998 was called by library. Now library use its own command reply
999 function for INFO command.
1001 Added function silc_client_command_call to call a command.
1002 Application can use it to call command, not access the structure
1005 Now all commands that are sent by the client library (not
1006 explicitly sent by application) use own command reply functions.
1008 Affected files around lib/silcclient/ and in
1009 irssi/src/silc/core/.
1011 * Fixed the WHOIS command reply sending to chech better valid
1012 clients. It was possible to send incomplete list of replies.
1014 Fixed the WHOIS and IDENTIFY to send the request to router
1015 if normal server did not do it and did not find any results.
1017 Affected file silcd/command.c.
1019 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1021 * Moved the internal data from SilcClient context into its
1022 own file, not accesible to application. Affected files
1023 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1024 and other files in client library.
1026 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1028 * Added doc/examples installation target in Makefile.am.pre.
1031 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1033 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1034 commands the found client entry will be removed from the
1035 cache, after notifying application about the error. Affected
1036 file lib/silcclient/command_reply.c.
1038 * Changed the /MSG to check for exact nickname user gave, and
1039 not let `nick' match `nick@host' if it is only one found. Now,
1040 user must type the exact nickname (like nick@host2) even if
1041 there are no more than one same nicks found. This is to avoid
1042 a possibility of sending nickname to wrong nickname since
1043 `nick' could match `nick@host'. Affected file is
1044 irssi/src/core/silc-servers.c.
1046 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1048 * Do not print "you are now server operator" or similar when
1049 giving /away command. Affected files are
1050 irssi/src/silc/core/client_ops.c, silc-servers.h.
1052 * Made the silc_server_command_pending_error_check to send
1053 the same command reply payload it received back to the
1054 original sender of the command. This way all arguments
1055 that was received by the server will be received by the
1056 client too. Affected file silcd/command.c.
1058 * Added the silc_idcache_add to return the created cache entry
1059 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1061 * Add global clients to expire if they are not on any channel.
1062 This is because normal server will never know if they signoff
1063 if they are not on any channel. The cache expiry will take
1064 case of these entries. This is done by normal servers only.
1065 The affected files are silcd/command_reply.c,
1066 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1068 * If server receives invalid ID notification for WHOIS or
1069 IDENTIFY and the ID exists in the lists, it is removed.
1070 Affected file silcd/command_reply.c.
1072 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1073 in client then client entry that it matches is searched and
1074 the nickname is printed on the screen for user. Affected
1075 file irssi/src/silc/core/client_ops.c.
1077 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1079 * Use cache entry expire time in the LIST command reply to
1080 purge old entries from the cache after the LIST command
1081 reply has been received. This way we don't have non-existent
1082 entries in the cache for too long. Affected file is
1083 silcd/command_reply.c.
1085 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1087 * If we are normal server, and we've not resolved client info
1088 in WHOIS or IDENTIFY from router, and it is global client,
1089 we'll check whether it is on some channel. If it is not
1090 then we cannot be sure about its validity and will resolve it
1091 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1092 file silcd/command.c.
1094 * Search channel by name (if possible) rather than by ID
1095 in IDENTIFY command's command reply. Affected file is
1096 silcd/command_reply.c.
1098 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>

1101 Updated specs and implemented it. Affected file silcd/command.c,
1102 silcd/packet_send.c and silcd/packet_receive.c.
1104 * Implemented the <founder auth> payload handling in the JOIN
1105 command. If provided all conditions for channel joining
1106 except requirement to provide correct passphrase can be
1107 overrided by the channel founder. Updated the protocol specs.
1108 Affected file silcd/command.c.
1110 Added support for founder auth in JOIN command in client
1111 library. Fixed the parsing of the JOIN command now to support
1112 all options as they should be. The affected file is
1113 lib/silcclient/command.c.
1115 * Optimized the WHOIS and IDENTIFY commands to send the request
1116 to router only if it includes nicknames or other names. If
1117 they include only IDs then check the local cache first before
1118 routing. Affected file is silcd/command.c.
1120 * Added channels topic announcements. Affected file is
1121 silcd/packet_receive.c and silcd/server.c.
1123 * Fixed the silc_server_send_notify_topic_set to really destine
1124 the packet to channel. Affected file silcd/packet_send.c.
1126 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1127 library. Affected file lib/silcclient/client_notify.c.

1140 lib/silccore/silccommand.c
1141 lib/silccore/silcidcache.c
1146 * ROBOdoc documented the lib/silcske/groups.h file and a
1147 bit changed the interface for better.
1149 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1151 * Update the client entry context in the ID cache after
1152 nick change. Affected file lib/silcclient/command.c.
1153 Fixes the CUMODE command when regaining founder privileges,
1154 and a little WHOIS problem.
1156 * Fixed silc_net_gethostbyname to correctly call the
1157 inet_ntop. Affected file lib/silcutil/silcnet.c.
1159 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1161 * Added IPv6 support checking to the configure.in.pre, added
1162 also --enable-ipv6 option to override the check. Affected
1163 file configure.in.pre.
1165 * The silc_thread_create now calls the start function
1166 directly if threads support is not compiled in. Removes
1167 ugly #ifdef's from generic code. Affected files are
1168 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1170 * Added silc_net_gethostby[name/addr]_async to asynchronously
1171 resolve. Affected files are lib/silcutil/silcnet.[ch].

1174 channel IDs. Affected file lib/silcutil/silcutil.c.
1176 * Added support for creating IPv6 based server IDs. Affected
1177 file is silcd/serverid.c.
1179 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1181 * Added silc_net_gethostby[addr/name] into the
1182 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1183 routines. Added silc_net_is_ip[4/6]. Affected file is
1184 lib/silcutil/unix/silcunixnet.c. All routines that take
1185 address as argument now supports both IPv4 and IPv6 addresses.
1187 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1189 * Fixed LIST command reply sending in server. Affected file
1192 * Server now sends the kicker's client ID in the KICK notify
1193 to the kicked client. Affected file silcd/command.c.
1195 * The client library now parses the kickers client ID and
1196 UI displays it. Affected files lib/silcclient/client_notify.c
1197 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1199 * Made all payload parsing function prototypes consistent.
1200 They all take now const unsigned char * and uint32 pair as
1201 the payload data instead of SilcBuffer. Changes all around
1202 the source tree. Other unsigned char* -> const unsigned char*
1203 changes around the tree as well.
1205 * Optimized SFTP client and server packet sending not to
1206 allocate new buffer for each packet but to recycle the
1207 first allocated buffer. Affected files are
1208 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1210 * Optimized the SFTP client to use SilcList instead of
1211 SilcDList for requests, because it is faster. Affected file
1212 is lib/silcsftp/sftp_client.c.
1214 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1215 into lib/silccore/silcid.[ch].
1217 Renamed silcpayload.[ch] into silcargument.[ch].
1219 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1221 * If client entry is deleted with active key agreement
1222 session, abort the session.
1224 The silc_client_abort_key_agreement now calls the completion
1225 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1227 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1230 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1232 * Don't use __restrict in older GCC's. Affected file is
1233 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1235 * silc_net_localhost now attempts to reverse lookup the
1236 IP/hostname. Affected file lib/silcutil/silcnet.c.
1238 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1239 command. It can be used to gain founder privileges at
1240 the same time when joining the channel.
1242 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1243 kicker's client ID as well. Updated protocol specs.
1245 Defined that the server must send SILC_COMMAND_IDENTIFY
1246 command reply with error status to client who sent
1247 private message with invalid client ID.
1249 Updated the protocol specification.
1251 * Added silc_server_send_command_reply to send any
1252 command reply. Affected file silcd/packet_send.[ch].
1254 * Added silc_id_payload_encode_data to encode ID payload
1255 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1257 * The server now send IDENTIFY command reply with error
1258 status if client ID in private message is invalid. Affected
1259 file silcd/packet_receive.c.
1261 * Save the server key file with server's IP address in
1262 the filename instead of hostname. The affected file is
1263 irssi/src/silc/core/client_ops.c.
1265 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1267 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1270 * Added libtool support for compiling shared objects in
1271 lib/silcsim. Affected file configure.in.pre and
1272 lib/silcsim/Makefile.am. Original patch by cras.
1274 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1276 * Pid file configuration, and server's config file fixes
1277 patch by toma. Updated CREDITS file.
1279 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1281 * Fixed silc_client_channel_message to not try to decrypt
1282 the message twice if it resolved the destination client
1283 information. This could cause of dropping one channel
1284 message. Affected file lib/silcclient/client_channel.c.
1286 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1288 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1289 lib/silcclient/client.c. This function is used when the SILC
1290 Client is run under some other scheduler, or event loop or
1291 main loop. On GUI applications, for example this may be
1292 desired to used to run the client under the GUI application's
1293 main loop. Typically the GUI application would register an
1294 idle task that calls this function multiple times in a second
1295 to quickly process the SILC specific data.
1297 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1299 * Fixed silc_server_drop() for dropping the supplementary
1300 groups as well, this could cause a security hole on some
1303 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1305 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1308 * Write PID file after dropping privileges. Added -F option
1309 to run server on foreground. A patch by debolaz.
1310 Affected files silcd/server.c, silcd/silcd.c.
1312 * Fixed MOTD to return the MOTD file server name. Affected
1313 file silcd/command.c.
1315 * Added INFO command reply handling to the Irssi SILC Client.
1316 Affected file irssi/src/silc/core/client_ops.c.
1318 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1320 * Fixed the silc_idcache_list_* routines to really support
1321 the dynamic list. Fixes a crash. Affected file is
1322 lib/silccore/silcidcache.c.
1324 * Fixed the LIST command reply to really call LIST command's
1325 pending callbacks. Affected file silcd/command_reply.c.
1327 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1329 * Update conn->local_entry->nickname after giving NICK
1330 command. Affected file lib/silcclient/command.c.
1332 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1334 * Added the [pid] option to the silcd configuration file
1336 Affected files: serverconfig.[ch] and silcd.c
1338 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1340 * Save fingerprint in WHOIS command reply in server.
1341 Affected file silcd/command_reply.c.
1343 * Fixed NICK commands pending callback registration.
1344 Affected file lib/silcclient/command.c.
1346 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1348 * Use ++server->cmd_ident when sending commands in server,
1349 instead of random number. Affected file silcd/command.c.
1351 * Fixed GETKEY command reply to call actually GETKEY pending
1352 command callbacks. Affected file silcd/command_reply.c.
1354 * A bit stricter check for nicknames. Check for same nickname
1355 in NICK command also. Affected file silcd/command.c.
1357 * Do not call INFO command everytime client ID changes, only
1358 during first connecting. Affected file lib/silcclient/client.c.
1360 * Set the new nickname only after successful command reply for
1361 NICK command is returned by server. Affected file
1362 lib/silcclient/command.c.
1364 * Remove nicknames from nicklist during server_signoff notify.
1365 Should fix /NAMES bit more. The affected file is
1366 irssi/src/silc/core/silc-channels.c.
1368 * Added `fingerprint' field to the SilcIDListData in the
1369 silcd/idlist.h to hold the fingerprint of the client's
1372 Send the fingerprint of the client's public key in WHOIS
1375 Affected files silcd/command.c, and silcd/idlist.[ch].
1377 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1378 create fingerprint from given data.
1380 * Show the fingerprint of the client's public key in WHOIS.
1381 Affected files irssi/src/module-formats.[ch] and
1382 irssi/src/silc/core/client_ops.c.
1384 * Format the multiple same nicknames also during JOIN and
1385 NICK_CHANGE notifys. Affected file is
1386 lib/silcclient/client_notify.c.
1388 * Do not print error on screen for invalid private message
1389 payload since it can come if someone is sending private
1390 messages with wrong key. Affected file
1391 lib/silccore/silcprivate.c.
1393 * Fixed multiple concurrent /PING crash. Affected file
1394 lib/silcclient/command.c.
1396 * Changed the wrong ID encoding. All IP addresses must be
1397 in MSB first order in encoded format. They were encoded
1398 wrong and was in LSB format. Affected files are
1399 silcd/serverid.c, lib/silcutil/silcutil.c.
1401 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1403 * Call the `connect' client operation through the scheduler
1404 in case of error. Affected file lib/silcclient/client.c.
1406 * Call the `failure' client operation even if the error
1407 occurred locally during a protocol. Affected file is
1408 lib/silcclient/protocol.c.
1410 * Added support of sending LIST command to router from normal
1411 server. This way normal server can get list of all channels
1412 in the network too. Fixed the channel list sending in the
1413 server too. Affected files are silcd/command.c, and
1414 silcd/command_reply.[ch].
1416 * Added silc_server_update_channels_by_server and
1417 silc_server_remove_channels_by_server. They are used during
1418 disconnection of primary router and in backup router protocol.
1419 Affected file silcd/server_util.[ch], silcd/server.c and
1420 silcd/server_backup.c.
1422 * Fixed channel adding to global list in IDENTIFY command
1423 reply in server. Affected file silcd/command_reply.c.
1425 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * If the incoming packet type is REKEY or REKEY_DONE process
1428 that packet always synchronously. Fixes yet another MAC
1429 failed error on slow (dialup) connections. Affected file
1430 lib/silcclient/client.c and silcd/server.c.
1432 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1434 * Call check_version SKE callback for initiator too. Affected
1435 file lib/silcske/silcske.c.
1437 * Implemented fix for security hole found in the SKE that was
1438 fixed in the specification few days back; the initiator's
1439 public key is now added to the HASH value computation.
1440 Added backwards support for the old way of doing it too, for
1441 old clients and old servers. Affected file is
1442 lib/silcske/silcske.c.
1444 * Enabled mutual authentication by default in SKE. If initiator
1445 is not providing mutual authentication the responder will
1446 force it. This will provide the proof of posession of the
1447 private key for responder. The affected files are
1448 lib/silcclient/protocol.c and silcd/protocol.c.
1450 * Do not cache anymore the server's public key during SKE.
1451 We do mutual authentication so the proof of posession of
1452 private key is done, and if the server is authenticated in
1453 conn auth protocol with public key we must have the public
1454 key already. Affected file silcd/protocol.c.
1456 * Added new global debug variable: silc_debug_hexdump. If
1457 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1458 file lib/silcutil/silclog.[ch].
1460 * Fixed compilation warning due to char * -> const char *.
1461 Affected files lib/silcutil/silcnet.h, and
1462 lib/silccore/silcauth.[ch].
1464 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1466 * Fixed CMODE command when new channel key was created. If
1467 the creation failed the old key was removed. Next time giving
1468 same command would crash the server since the old key was
1469 freed already. Affected file silcd/command.c.
1471 * Fixed the silc_server_announce_get_channels to not crash
1472 on reconnect. Affected file silcd/server.c.
1474 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1476 * Added silc_log_set_debug_string function to set a regex
1477 string to match for debug output. Only the function names,
1478 or filenames matching the given debug string is actually
1479 printed. This way it is possible to filter out those debug
1480 strings that user is not interested in.
1482 Fixed a bug in silc_string_regexify.
1484 Affected files lib/silcutil/silclog.[ch], and
1485 lib/silcutil/unix/silcunixutil.c.
1487 * Changed the -d options in both server and Irssi SILC client
1488 to take the debug string as argument. Affected files
1489 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1491 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Added silc_hash_babbleprint to create a Bubble Babble
1494 Encoded fingerprint. The encoding is developed by Antti
1495 Huima (draft-huima-babble-01.txt), and it creates human
1496 readable strings out of binary data. Affected file
1497 lib/silccrypt/silchash.[ch].
1499 * Print the babble print now in addition of fingerprint as well
1500 in Irssi SILC client. Affected files are
1501 irssi/src/fe-common/silc/module-formats.[ch],
1502 irssi/src/fe-common/silc/core/client_ops.c.
1504 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1506 * Fixed a security problem found in SKE. The initiator's
1507 public key too is now added to the HASH hash value creation
1508 which is signed by the responder to create the SIGN value.
1509 This will prevent anyone in the middle to lie to the responder
1510 about the initiator's public key. If this is done now, the
1511 man in the middle will get caught. Updated the protocol
1514 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1516 * Better installation directory handling. Configure module
1517 paths and other paths automatically to example_silc* files
1518 in doc/. A patch by toma.
1520 * Fixed compiler warning from MPI library, and from SILC RNG.
1523 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1524 It can be configured with ./configure. A patch by toma.
1526 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Find correct make to use in prepare-clean. A patch by
1529 toma. Affected file prepare-clean.
1531 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1533 * Added irssi variables use_auto_addr, auto_bind_ip,
1534 auto_bind_port and auto_public_ip.
1536 * Changed the interface for silc_client_send_key_agreement
1537 in lib/silcclient/silcapi.h
1541 irssi/src/silc/core/silc-core.c
1543 lib/silcclient/silcapi.h
1544 irssi/src/silc/core/silc-channels.c
1545 lib/silcclient/client_keyagr.c
1548 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1550 * Added silc_pkcs_public_key_compare to compare two
1551 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1553 * Check that the client who set the founder mode on the
1554 channel is the same client that is giving the founder
1555 mode to itself. It is done by comparing the saved public
1556 key (it is saved even in the authentication is passphrase).
1557 Affected file silcd/command.c.
1559 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1561 * Do not process packet for disconnected socket connection.
1562 Affected file lib/silccore/silcpacket.c.
1564 * Process the DISCONNECT packet through scheduler in the
1565 client library. Affected file lib/silcclient/client.c.
1567 * Fixed the silc_client_packet_parse to not to increase
1568 the packet sequence number if the conn->sock and the
1569 current socket connection is not same. This can happen
1570 for example during key agreement when the conn includes
1571 multiple socket connections (listeners). Affected file
1572 lib/silcclient/client.c.
1574 * The sender of the file transfer request now provides also
1575 the pointer (listener) for the key exchange protocol. If
1576 the listener cannot be created then it sends empty key
1577 agreement and lets the receiver provide the listener.
1579 Added `local_ip' and `local_port' arguments to the
1580 silc_client_file_send. If they are provided they are used,
1581 if not then it will attempt to find local IP address, if
1582 not found or bind fails then the remote client will provide
1585 Affected files are lib/silcclient/client_ftp.c and
1586 lib/silcclient/silcapi.h.
1588 * Extended the FILE SEND command to support defining the
1589 local IP and port for key exchange listener. They are
1590 optional. Affected file irssi/src/silc/core/silc-servers.c.
1592 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1594 * Defined to WHOIS command reply the sending of fingerprint
1595 of the client's public key (if the proof of posession of the
1596 corresponding private key is verified by the server).
1597 Updated to the protocol specification.
1599 * Added support of receiving the client's public key's
1600 fingerprint in command reply in client library. Affected
1601 file is lib/silcclient/command_reply.c, and
1602 lib/silcclient/idlist.[ch].
1604 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1606 * Do not send over 128 chars long nickname to the server
1607 in NICK command. Affected file lib/silcclient/command.c.
1609 * Do not send over 256 chars long channel names to the server
1610 in JOIN command. Affected file lib/silcclient/command.c.
1612 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1614 * Assure that silc_server_close_connection cannot be called
1615 twice for same socket context. Affected file is
1618 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * Send error message to application if opening file for
1621 writing during file transfer fails. Affected file is
1622 lib/silcclient/client_ftp.c.
1624 Remove all file transfer sessions for a client that we're
1625 removing from ID cache.
1627 Affected file is lib/silcclient/client_ftp.c.
1629 * Fixed silc_net_addr2bin to return correct address. Affected
1630 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1632 * Fixed file transfer session removing on signoff notify.
1633 Affected file irssi/src/silc/core/silc-servers.c.
1635 * Added the SilcClientFileError to be returned in the monitor
1636 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.

1657 client library. Affected file lib/silcclient/client_prvmsg.c.
1659 * Do not actually remove the client directly from ID cache
1660 during SERVER_SIGNOFF, but invalidate it. This way we
1661 preserve the WHOWAS info for the client. Affected file
1662 silcd/server_util.c.
1664 * Fixed SERVER_SIGNOFF notify handling in the server. The
1665 server is now able to process incoming SERVER_SIGNOFF notify
1666 for a server that it doesn't even know about. It will remove
1667 the clients provided in the notify. Affected file
1668 silcd/packet_receive.c.
1670 * Check for partial packet in data queue after every packet that
1671 was found from the queue. Return and wait for more data if
1672 there is partial data in queue. Affected file is
1673 lib/silccore/silcpacket.c.
1675 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1683 * Check that newsize in silc_buffer_realloc is larger than
1684 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1686 * Added better monitor of file transfers. It now monitors
1687 key agreement protocol during the file transfer too. Added
1688 error reporting too. Affected files
1689 irssi/src/silc/core/silc-servers.c,
1690 irssi/src/fe-common/silc/module-formats.[ch].
1692 * Wrote a help file for FILE command.
1694 * Added silc_rng_global_get_byte_fast to get not-so-secure
1695 random data as fast as possible. Random data is read from
1696 /dev/urandom if available and from the SILC RNG if not
1697 available. It is used in padding generation. Affected file
1698 lib/silccrypt/silcrng.[ch].
1700 * All packets in client library are now processed synchronously.
1701 Optimized packet processing a lot. Affected file
1702 lib/silcclient/client.c.
1704 * All server connection packets are processing synchronously
1705 now in server, to optimize packet processing. Affected file
1708 * Include files are installed now only in Toolkit distribution
1709 if make install is given. Affected files: all Makefile.am's.
1711 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1713 * Assure that silc_client_notify_by_server_resolve does not
1714 resolve the client information multiple times. If it cannot
1715 be found by the first it cannot be found at all. Affected
1716 file lib/silcclient/client_notify.c.
1718 * Fixed WHOWAS command reply calling. Affected file
1719 lib/silcclient/command_reply.c.
1721 * Removed all references to silc_idlist_get_client from the
1722 Irssi SILC client since that call is internal call used by
1723 the library. The Irssi SILC client will use now client
1724 retrieval functions found in silcapi.h.
1726 * Fixed a bug in resolving nickname info before sending
1727 private message. It used freed memory. Affected file
1728 irssi/src/silc/core/silc-servers.c.
1730 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1732 * Assure my_channels statistics cannot go negative in server.
1733 Affected files silcd/server.c, silcd/server_util.c.
1735 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1749 * Added silc_net_localip to return local host's IP address.
1750 Affected file lib/silcutil/silcnet.[ch].
1752 * If key exchange or rekey protocol is active for a connection
1753 parse all packets syncronously since there might be packets
1754 in packet queue that we are not able to process without first
1755 processing packets before them. Affected file silcd/server,
1756 lib/silcclient/client.c.
1758 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1759 whether library should continue processing the packet.
1760 Affected file lib/silccore/silcpacket.h.

1791 lib/silcutil/silcutil.[ch].
1793 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1795 * Resolve the client info when received private message or
1796 channel message for a client which nickname we don't know.
1797 Affected files lib/silcclient/client_prvmsg.c and
1798 lib/silcclient/client_channel.c.

1806 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1807 is incomplete and is being resolved, it won't be resolved
1810 Make sure also that USERS command reply does not resolve
1811 twice information. Affected file is
1812 lib/silcclient/command_reply.c.
1814 Make sure that silc_client_get_clients_by_list does not
1815 resolve twice same information.
1817 * Check for valid client->id in the silc_server_free_client_data.
1818 Affected file silcd/server.c.
1820 * Fixed /GETKEY nick@server not to crash if the server entry
1821 is not found. Affected file lib/silcclient/command.c.
1823 * Fixed the silc_server_check_cmode_rights to check the
1824 requested modes correctly. Affected file silcd/command.c.

1829 Affected file silcd/command.c.
1831 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Call the silc_server_udpate_servers_by_server in the
1834 primary router that comes back online in the backup resuming
1835 protocol. Otherwise it routes packets wrong. Affected file
1836 silcd/server_util.[ch], silcd/server_backup.c.
1838 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1841 lib/silcutil/silcbuffmt.[ch].
1843 * Redefined the SILC packet header to include the padding
1844 length. Affected file lib/silccore/silcpacket.[ch].
1846 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1847 length for maximum padding up to 128 bytes). Affected
1848 file lib/silccore/silcpacket.h.
1850 * Removed all backwards support for old 0.5.x MAC thingies.
1851 The SILC packet header change makes it impossible to be
1852 backwards compatible.
1854 * Send the ENDING packet with timeout in the backup resuming
1855 protocol. This is to assure that all routers has connected
1856 to the primary router. Affected file silcd/server_backup.c.
1858 * Changed the RNG to take the first IV from random data. It
1859 used to take it from zero actually. Changed the RNG also
1860 to use /dev/urandom during session. /dev/random is used
1861 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1863 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Changed the SILC packet header to have the first two bytes
1866 (the packet length) encrypted. Affected files aroung the
1867 code tree, lib/silccore/silcpacket.[ch]. Removed the
1868 SilcPacketCheckDecrypt callback. It is not needed anymore
1869 since the silc_packet_receive_process will determine now
1870 whether the packet is normal or special.
1872 * Implemented the unidirectional MAC keys. Affected files
1873 lib/silcske/silcske.c, silcd/protocol.c and
1874 lib/silcclient/protocol.c.
1876 * Implemented the packet sequence number to the MAC computation.
1877 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1878 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1879 lib/silcclient/protocol.c.
1881 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * Allow backup router to announce servers. All servers
1884 announced by backup router are added to the global list
1885 automatically. Update hte server's socket to our primary
1886 router also when backup router announces a server.
1887 Affected file silcd/packet_receive.c.
1889 * Do not update the client->router in the function
1890 silc_server_udpate_clients_by_server if the client is on
1891 global list. We might fail to find any specific server
1892 for locally connected clients and local cell clients. They
1893 should still use the `from' and not `to' as client->router.
1894 This fixes backup router resuming protocol. Affected file
1895 silcd/server_util.c.
1897 * Decrease channel statistics count only if the channel
1898 deletion worked. Affected files are silcd/server.c and
1899 silcd/server_util.c.
1901 * Added silc_server_update_servers_by_server to update origin
1902 of all server entries. Used during backup router protocol.
1903 Affected files silcd/server_util.[ch], silcd/server.c. and
1904 silcd/backup_router.c.
1906 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1907 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1908 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1909 lib/silccrypt/silchmac.c.
1911 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Assure that router cannot reroute the same channel message
1914 to the sender. Affected file silcd/packet_receive.c.
1916 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Made better checks that the channel message is not sent
1919 to the router it came from. Affected file is
1920 silcd/packet_send.c. Fixed memory leak too.
1922 * Announce informations for incoming router connection, but
1923 only after checking if it is replaced by backup router.
1924 Affected file silcd/packet_receive.c.
1926 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1928 * Fixed the backup resuming protocol to work in multiple
1929 router environment. Affected file silcd/server_backup.c.
1931 * Route packet only to one router in the function
1932 silc_server_packet_send_to_channel. Affected file is
1933 silcd/packet_send.c.
1935 * Fixed silc_server_send_notify_dest to set the broadcast
1936 flag. Fixed the silc_server_send_notify_topic to actually
1937 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1938 Affected file silcd/packet_send.c.
1940 * Changed the SFTP Filesystem interface. Changed the
1941 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1942 the filesystem operation function. The SilcSFTPFilesystem
1943 is now a context that is allocated by all filesystem allocation
1944 functions and it already includes the operations structure
1945 and filesystem specific context. It is given as argument
1946 now to the silc_sftp_server_start. This made the interface
1947 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1948 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1950 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1952 * Changed the backup router adding and getting interfaces
1953 in the server. The router that will be replaced by the
1954 specified backup router is now sent as argument. Affected
1955 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1958 * Added silc_net_addr2bin_ne to return the binary form of
1959 the IP address in network byte order. Affected files
1960 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1962 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * Check for existing server ID in silc_server_new_server
1965 and in silc_server_connect_to_router_final and remove the
1966 old entry if it exists. Affected file silcd/packet_receive.c,
1969 * Send the channel message always to only one router, either
1970 in upstream or downstream. Affected file is
1971 silcd/packet_send.c.
1973 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Wrote the definition of the backup resuming protocol to the
1976 protocol specification.
1978 * Removed one redundant channel key generation from normal
1979 server during joining procedure. Removed one redundant
1980 channel key sending from server to router during joining
1981 procedure. Affected file silcd/command.c.
1983 * Made minor bugfixes to the backup router resuming protocol.
1984 Affected file silcd/server_backup.c, server.c.
1986 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1988 * Added --disable-asm configuration option. Affected files
1989 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1992 * Implemented the backup resuming protocol that is used to
1993 resume the primary router position in the cell after the
1994 primary router comes back online. Affected files
1995 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1996 and silcd/server_util.[ch].
1998 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * Sleep two (2) seconds after sending QUIT command to server.
2001 Affected file lib/silcclient/command.c.
2003 * Assure that if outgoing data buffer is pending do not force
2004 send any data. Affected file silcd/packet_send.c.
2006 * Assure that if outgoing data buffer is pending do not force
2007 send any data. Affected file lib/silcclient/client.c.
2009 * Implemented the backup router support when the primary router
2010 goes down. The servers and routers can now use the backup
2011 router as new primary router without loosing connectivity.
2013 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2015 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2016 in the server to indicate disabled entry. All data read
2017 from the connection will be ignored and no data is sent
2018 for entry that is disabled. Affected files are
2019 silcd/idlist.h, silcd/server.c.
2021 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2023 * Created SFTP client and server test programs in the
2024 lib/silcsftp/tests directory.
2026 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Implemented memory filesystem (virtual filesystem) for
2029 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2032 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Implemented the SFTP (SSH File Transfer Protocol) to the
2035 lib/silcsftp. It includes SFTP client and SFTP server
2038 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Moved lib/silccore/silcprotocol.[ch] to the
2041 lib/silcutil library.
2043 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2044 take variable argument list pointer as argument. Affected
2045 file lib/silcutil/silcbuffmt.[ch].
2047 * Added silc_buffer_set function that is used to set data
2048 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2049 Affected file lib/silcutil/silcbuffer.h.
2051 * Changed various routines in the core library to use the new
2052 silc_buffer_set instead of allocating new buffer only for
2055 * Added 64-bit value formatting and unformatting support to the
2056 silc_buffer_[un]format routines. Affected file is
2057 lib/silcutil/silcbuffmt.[ch].
2059 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2060 to includes/bitmove.h.
2062 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2064 * Fixed channel user mode saving in client library. Affected
2065 file lib/silcclient/command[_reply].c.
2067 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2069 * Defined the file transfer to the SILC Protocol. Added
2070 new packet type SILC_PACKET_FTP and defined File Transfer
2071 Payload. The mandatory file transfer protocol is SFTP
2072 (SSH File Transfer Protocol). Affected file in addition
2073 of the internet draft is lib/silccore/silcpacket.h.
2075 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2076 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2077 is used as part of backup router protocol when the primary
2078 router of the cell is back online and wishes to resume
2079 the position as primary router.
2081 * Redefined the MAC generation keys in the protocol. The
2082 same key is not used anymore in both direction. Both
2083 direction will now use different keys for sending and
2084 receiving. This fixes a potential security flaw. This
2085 change causes incompatibilities in the protocol.
2087 * Redefined also the MAC computation from the packet.
2088 An packet sequence number is now added to the MAC
2089 computation. This prevents possible replay attacks against
2090 the protocol. This change too causes incompatibilities
2093 Added `sequence' field to the SilcPacketContext to hold
2094 the current sequence number for the packet.
2096 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * Added `created' field to the SilcIDListData in the file
2099 silcd/idlist.h to indicate the time when the entry was
2102 * Added `created' field to the SilcChannelEntry too. Affected
2103 file silcd/idlist.h.
2105 * Added `creation_time' aguments to all the announcement functions
2106 in the server. If it is provided then only the entries that
2107 was created after the provided time frame are actually
2108 announced. Affected file silcd/server.[ch].
2110 * The protocol says that the Channel ID's IP address must be
2111 based on the router's IP address. Added check for this in
2112 the silc_server_new_channel when processing incoming New Channel
2113 Payload. Affected file silcd/packet_receive.c.
2115 * Print out the correct version with --version in SILC client.
2116 Affected file irssi/src/silc/core/silc-core.c.
2118 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Fixed WHOWAS command to check for completnes of the client
2121 entry always, not just when the command is coming from client.
2122 Affected file silcd/command.c.
2124 * Added new function silc_server_packet_queue_purge to purge the
2125 outgoing data queue to the network. After the function returns
2126 it is guaranteed that the outgoing packet queue is empty.
2127 Affected file silcd/packet_send.[ch].
2129 * Purge the outgoing packet queue in the rekey protocol's final
2130 callback to assure that all rekey packets go to the network
2131 before quitting the protocol. Affected file silcd/server.c.
2133 * Added silc_client_packet_queue_parse as similar function as
2134 in server to the client library. The affected file is
2135 lib/silcclient/client.c.
2137 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2139 * Splitted silcd/server.c and created silcd/server_util.[ch]
2140 for utility functions.
2142 * Added new socket flag SILC_SF_DISABLED to indicate that the
2143 connection is open but nothing can be sent to or received from
2144 the connection. Affected file lib/silcutil/silsockconn.[ch].
2145 The checking for disabled socket is checked in the low level
2146 silc_socket_write and silc_socket_read functions.
2148 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * Allow only nicknames and channel names that fits into the
2151 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2153 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2155 * When processing JOIN command reply in server check that if
2156 the channel exists in our global list we'll move it the local
2157 list. Affected file silcd/command_reply.c.
2159 * Fixed the check whether client is joined on the channel already
2160 in JOIN command. Affected file lib/silcclient/command.c.
2162 * Fixed the JOIN command reply to check whether the channel
2163 already exists. Affected file lib/silcclient/command_reply.c.
2165 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2167 * Added silc_ske_status_string to map the SKE error numbers
2168 to readable strings. The affected files are
2169 lib/silcske/silcske[_status].[ch].
2171 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2173 * Do not show the private channels on the WHOIS channel list
2174 as it is not allowed by the protocol. The affected file is
2177 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Assure that the packet length digged from the actual packet
2180 is something sensible in the silc_packet_decrypt_rest_special
2181 in lib/silccrypt/silcpacket.c.
2183 * Free and NULL the allocated pointer in silc_hmac_alloc if
2184 the HMAC allocation fails. The affected file is
2185 lib/silccrypt/silchmac.c.
2187 * Print the selected security properties to the log files in
2188 the server. Affected file silcd/protocol.c.
2190 * Add SKE's reference counter even if calling the completion
2191 callback manually. Otherwise it goes negative, although it
2192 does not cause any problems. The affected file is
2193 lib/silcske/silcske.c.
2195 * Remove the client entry with short timeout after giving the
2196 KILL command. Affected file lib/silcclient/command.c.
2198 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2199 case all found clients are already disconnected (WHOWAS would
2200 found them) in the server. Affected file silcd/command.c.
2202 * Update the last_receive (time of last data received) to be
2203 updated only when received private or channel message so that
2204 the idle time showed in WHOIS makes more sense.
2206 * Added boolean field `valid' in to the SilcClientEntry in the
2207 client library to indicate whether the entry is valid or not.
2208 This fixes the nickname change bug on channel when changing
2209 the nickname to be same than the old (like nick to Nick) the
2210 nickname formatter doesn't set the new nick anymore to Nick@host.
2211 Affected file lib/silcclient/idlist.[ch].
2213 * Now actually fixed the nickname changing on disconnection.
2214 Added new function silc_change_nick to the Irssi SILC Client.
2215 Affected file irssi/src/silc/core/client_ops.c,
2216 irssi/src/silc/core/silc-nicklist.[ch].
2218 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2220 * Check that the public key exists in the GETKEY command before
2221 trying to encode it. Affected file silcd/command.c.
2223 * Print some notifications on received public keys with GETKEY
2224 command in the Irssi SILC Client. Affected files are
2225 irssi/src/fe-common/silc/module-formats.[ch],
2226 irssi/src/silc/core/client_ops.c.
2228 * Use IDENTIFY command to resolve the server information in the
2229 GETKEY command instead of INFO command. Affected file
2230 lib/silcclient/command.c.
2232 * All command reply functions in the client library now calls
2233 the pending command reply callbacks even if an error has
2234 occurred. The server has done this a long time and now it was
2235 time to move the client library to this as well. Now all
2236 errors can be delivered back to the pending command reply
2237 callbacks if necessary. Affected files are
2238 lib/silcclient/command[_reply].[ch].
2240 * Change the nickname on disconnection back to the username
2241 because in reconnect the server will enforce it to it anyway.
2242 Affected file irssi/src/silc/core/silc-servers.c.
2244 * Fixed a config file parsing bug in the Irssi SILC client.
2245 Affected file irssi/src/silc/core/clientconfig.c.
2247 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2249 * When printing the channel mode on JOIN, verify that the
2250 channel key and channel's HMAC are valid. Affected file
2251 irssi/src/silc/core/client_ops.c.
2253 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2255 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2256 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2257 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2259 * Removed channel key rekey task deleting from the function
2260 silc_server_save_channel_key. Affected file silcd/server.c.
2261 Added explicit timeout task context instead that is used to
2262 delete the task if we are registering a new task before the
2263 new task has elapsed.
2265 * When channel key rekey occurs the client library now saves
2266 the old channel key for a short period of time (10 seconds) and
2267 is able to use it in case some is still sending channel
2268 messages encrypted with the old key after the rekey. Affected
2269 file lib/silcclient/[idlist.h|client_channel.c].
2271 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * Added check to the silc_server_new_id_real to not accept
2274 new ID if it is the sender's own ID. Affected file is
2275 silcd/packet_receive.c.
2277 * Assure that we do not announce ourself or the one we've
2278 sending our announcements when we're router and are announcing
2279 servers to our primary router. Affected file silcd/server.c.
2281 * Fixed silc_server_command_identify_check_client to assemble
2282 correct WHOIS packet. It send corrupted WHOIS packet and
2283 caused problem with router to router connections. Affected
2284 file silcd/command.c.
2286 Fixed also silc_server_command_whois_check the same way
2287 as for the IDENTIFY command.
2289 * Added new SilcIDListStatus to the server in the SilcIDListData
2290 structure. The status now includes the current status of
2291 the entry (like registered, resolved etc.). Affected file
2292 silcd/idlist.[ch]. Defined a bunch of different status types
2293 as well. This replaced the old boolean registered field as well.
2295 Added resolve_cmd_ident field to the SilcClientEntry structure
2296 too so that if the entry is for example being resolved so
2297 another command may attach to the same pending command reply
2298 without requiring to resolve the same entry again. This concept
2299 should optimize the WHOIS and the IDENTIFY resolving under
2300 heavy load by taking away unnecessary resolving for entries
2301 that are being resolved already.
2303 Added support for adding multiple pending commands for one
2304 command idenfier. Affected file silcd/command[_reply].[ch].
2306 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2307 before deleting the data. Otherwise the hash table will have
2308 freed data in comparison functions. Affected file is
2309 silcd/command_reply.c.
2311 * Fixed silc_idlist_replace_client_id to add the new entry to
2312 the cache with NULL nickname. Otherwise there will be invalid
2313 memory as the nickname after the nickname is freed. Affected
2314 file silcd/packet_receive.c.
2316 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2317 saved into wrong slots because the previous number of entries
2318 was not taken into account. Affected file silcd/idlist.c.
2319 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2321 * If we are router and we receive JOIN notify to a channel that
2322 does not have any users then notified client is marked as the
2323 channel founder, as it is it. The affected file is
2324 silcd/packet_receive.c
2326 * Added to the extended hash table API's table_del_*ext functions
2327 the destructor as argument too, so that the caller can decide
2328 which destructor to use or whether to use destructor at all.
2329 Affected file lib/silcutil/silchashtable.[ch].
2331 * Fixed ID Cache purging. It actually deleted the entries from
2332 the hash table after the data was freed. The hash table ended
2333 up comparing freed memory. The affected file is
2334 lib/silccore/silcidcache.c.
2336 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Fixed Irssi SILC client's KILL command's HELP syntax.
2340 * The USERS command now resolves the detailed user information
2341 if the userinfo field is missing. Affected file is
2342 lib/silcclient/command_reply.c.
2344 * Do not print error in silc_file_read if the read file does
2345 not exist. Just silently return NULL. Affected file is
2346 lib/silcutil/silcutil.c.
2348 * Fixed the silc_log_output to not wine about NULL filename
2349 and to not create some bogus " " filename. Affected file is
2350 lib/silcutil/silclog.c.
2352 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Fixed various printing bugs on the user interface in the
2355 Irssi SILC Client. Minor changes that were forgotten from
2358 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Fixed the configure.in.pre and the compilation and distribution
2361 environment to support the new autoconf 2.52. That version is
2362 now required to compile the CVS trunk.
2364 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2366 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2367 to generally parse user@fqdn format strings. Affected file
2368 lib/silcutil/silcutil.c.
2370 * Added nickname_format and nickname_force_format fields to the
2371 SilcClientParams structure. The first one defines the format
2372 for the nicknames that the library will enforce if the receives
2373 multiple same nicknames. The second one is boolean value and
2374 can be used to force the library to always enforce the format
2375 to the nicknames regardles whether there are multiple nicknames
2376 or not. This configurable formatting was employed to flexibly
2377 support accessing multiple nicknames from the user interface.
2378 The userinterface can now set the nicknames to what ever format
2379 they prefer. Affected file lib/silcclient/silcapi.h.
2381 Added function silc_client_nickname_format to the file
2382 lib/silcclient/idlist.c. It performs the nickname formatting.
2384 Added new field `hostname´ to the SilcClientEntry context.
2385 It holds the hostname of the client. Affected file is
2386 lib/silcclient/idlist.h.
2388 * Irssi SILC Client sets the nicknames in nick@hostn format.
2389 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2390 irssi/src/silc/core/silc-core.c.
2392 The WHOIS printing now also shows both the real nickname and
2393 the formatted nickname so that user knows how to access the
2394 user if there are multiple same nicknames cached. Affected
2395 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2396 printing formatting too to take the hostname now as a separate
2397 argument. The Affected file is
2398 irssi/src/fe-common/silc/modules-formats.[ch].
2400 * Changed the silc_client_get_clients_local to accept the formatted
2401 nickname as argument. It accepts the real nickname too but the
2402 formatted nickname can be used to find the true entry from
2403 multiple entries. Affected file lib/silcclient/silcapi.h and
2404 lib/silcclient/idlist.c.
2406 * Added nickname_format_parse field to the SilcClientParams.
2407 It is a callback function provided by the application to parse
2408 the nickname out of the formatted nickname string. The library
2409 calls it to get the nickname from the formatted string. Since
2410 the application generally knows better the format of the nickname
2411 string it parses it instead of the library, even though library
2412 encodes the formatted string. If the callback function is not
2413 provided then the library will use the string as is. The
2414 affected file is lib/silcclient/silcapi.h.
2416 * All the nickname strings passed to the client library in
2417 commands are now expected to be formatted nickname strings.
2418 If the command does not support the formatted nickname string
2419 it will assume that the sent string is the actual nickname.
2420 Affected file lib/silcclient/command.c.
2422 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2424 * Added public key authentication support to OPER and SILCOPER
2425 commands in the client library. Affected file is
2426 lib/silcclient/command.c.
2428 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * Changed the get_auth_methdod client operation to be asynchronous.
2431 It can be async if the application resolves the authentication
2432 method from the server during the negotiation. Added new
2433 SilcGetAuthMeth completion callback that the application will
2434 call after resolving the authentication method.
2436 Added function silc_client_request_authentication_method that
2437 the application can use to resolve the authentication method
2438 from the server. Added also SilcConnectionAuthRequest callback
2439 that the library will call after the server has replied. The
2440 application can call this function if it does not know the
2441 current authentication method.
2443 Affected files are lib/silcclient/client.c and
2444 lib/silcclient/silcapi.h.
2446 * The Irssi SILC client now automatically resolves the authentication
2447 method incase any configuration information is not present (and
2448 currently there never is). The affected file is
2449 irssi/src/silc/core/client_ops.c.
2451 * Fixed public key authentication from the client library.
2452 Affected file lib/silcclient/protocol.c. Changed also the
2453 protocol specification about the public key authentication in
2454 the connection authentication protocol. The actual data to be
2455 signed is now computed with a hash function before signing.
2457 * Fixed the public key authentication from the server as well.
2458 Affected file silcd/protocol.c.
2460 * Removed the mlock()'s from the memory allocation routines.
2461 Affected file lib/silcutil/silcmemory.c. The ./configure does
2462 not check anymore for the mlock(). Affected file is
2465 * Fixed USERS command in server to allow the execution of the
2466 command for private and secret channels if the client sending
2467 the command is on the channel. Affected file silcd/command.c.
2469 * Fixed silc_client_get_clients_local to return the clients
2470 count correctly. It could return wrong value. Affected file
2471 lib/silcclient/idlist.c.
2473 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2475 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2476 types. The assembler optimizations seemed not to like 64-bit
2477 data types. The assmebler optimizations thus are now enabled
2478 also for BSD systems as opposed to only enable them for Linux.
2480 * Do not check for threads at all on BSD systems. Affected
2481 file configure.in.pre.
2483 * Removed -n and -h options from the Irssi SILC Client since
2484 they are not used in silc.
2486 * Fixed the prime generation to assure that the first digit
2487 of the generated random number is not zero since our conversion
2488 routines does not like number strings that starts with zero
2489 digit. If zero digit is seen the random number is regenerated.
2490 This caused some corrupted RSA keys when the zero first digit
2491 was met. Affected file lib/silcmath/silcprimegen.c.
2493 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Fixed WIN32 configuration in the ./configure script.
2496 Fixed to include xti.h on environments that has it.
2497 Patches by Carsten Ilchmann and andrew.
2499 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Changed the silc_id_create_client_id to be collision
2502 resistant. It is now assured that there cannot be created
2503 two same client ID's. I suspect that some weird bugs in
2504 the server were actually caused by duplicate Client IDs.
2505 Affected file silcd/serverid.[ch]. A router receiving
2506 new ID now also assures and informs the sending server
2507 if the ID caused collision.
2509 * Changed the silc_id_create_channel_id to also assure that
2510 there are no collisions.
2512 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2514 * Statement about ignoring the Mutual Authentication flag when
2515 performing rekey with PFS was a bit misleading. It is ignored
2516 if it was set in the initial negotiation, it cannot be even
2517 set in the rekey. Fixed in the ke-auth draft. Started the
2518 new versions of the protocol drafts in the doc/.
2520 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2522 * Fixed a bug in silc_client_command_identify_save when saving
2523 new channel information. The channel name was no duplicated
2524 and caused crash on exit. Affected file is
2525 lib/silcclient/command_reply.c.
2527 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2529 * Fixed the getkey command handling in the server. Send just
2530 empty OK reply to the sender if the key could not be fetched
2531 (but everything else was ok, like the key just was not available).
2532 Changed the public key parameter to optional in the protocol
2533 specs so that empty OK reply can be sent. Affected file
2536 Added a message to Irssi SILC client to tell to user if the
2537 server did not return a public key.
2539 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2541 * Fixed a channel key regeneration bug. It registered new
2542 timeout tasks exponentially until all system resources were
2543 used. Affected file silcd/server.c.
2545 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Added the SILC Document generator to the scripts/silcdoc.
2548 It can be used to generate the Toolkit Reference Manual out
2549 of the source tree. Internally it will also use the RoboDoc
2550 generator now imported in util/robodoc.
2552 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2554 * Added couple of return's in rekey protocol if error orccurred
2555 during the protocol. The execution must be terminated.
2556 Affected file silcd/protocol.c. Also, terminate the protocol
2557 always with timeout.
2559 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2561 * The client's Client ID was created initally from the wrong
2562 nickname (it could have been in format nick@host) in the
2563 silc_server_new_client. Affected file silcd/packet_receive.c
2565 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Added some SILC_LOG_ERROR's to various error conditions
2568 if client could not be added to ID cache. Affected files
2569 silcd/packet_receive.c and silcd/server.c.
2571 * When client's sock->user_data is freed, NULL also the
2572 client->router and client->connection pointers. Added check
2573 for these pointers being NULL to various places around the
2574 code. Affected file silcd/server.c.
2576 * Added client->data.registered == TRUE checks to various
2577 places around the code to assure that unregistered client's
2578 are not handled when it is not allowed. Affected file
2581 * Added `bool registered' fields to all
2582 silc_idlist_[server|client]_get_* routines to indicate whether
2583 the fetched client needs to be registered or not. Affected
2584 file silcd/idlist.[ch].
2586 * Add your own entry as registered to the ID cache in the
2587 server. Affected file server.c.
2589 * Fixed a bug in silc_server_new_server. The SilcServer was
2590 set as the new server's context instead of SilcServerEntry.
2591 This naturally caused some weird bugs.
2593 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2595 * Do not delete the channel rekey task when adding it
2596 for in silc_server_create_channel_key.
2598 * Changed the silc_server_create_channel_key to return
2599 TRUE or FALSE to indicate the success of the channel key
2602 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2604 * Fixed MSVC++ project files and added missing files to
2605 Makefiles under win32/.
2607 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2609 * Do not add TCP_NODELAY flag if the operating system
2610 does not have it defined. Affected files are
2611 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2613 * Fixed buffer overflow from Irssi SILC Client. Affected
2614 file irssi/src/fe-common/core/themes.c.
2616 * Fixed double free in client library in the file
2617 lib/silcclient/client.c when disconnecting from server.
2619 * Applied double free patch from cras to Irssi SILC client.
2620 Affected files irssi/src/core/[modules/expandos].c
2622 * Fixed the disconnection handling to Irssi SILC Client.
2623 The application must call silc_client_close_connection
2624 in ops->connect client operation in case of failure of
2625 the connection. Affected file is
2626 irssi/src/silc/core/client_ops.c.
2628 * Do not set sock->protocol to NULL in the function
2629 silc_client_close_connection after executing the protocol's
2630 final callback since the sock might not be valid anymore.
2631 Affected file lib/silcclient/client.c.
2633 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2635 * Do not enable SILC_THREADS if the linking with libpthread
2636 did not happen. Affected file configure.in.pre.
2638 * Added notion to protocol specification that server must
2639 verify the sent authentication payload with CMODE when
2640 setting the channel founder key. Implemented it to the
2641 server. Affected file silcd/command.c.
2643 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2645 * Added _EXTRA_DIST SILC distribution variable to the
2646 distributions file. It is used to conditionally add extra
2647 files or directories to the specific distribution. Affected
2648 files ./prepare, Makefile.am.pre and distributions.
2650 Removed the `_' from the start of the distribution names.
2653 * Added README.WIN32 for instructions to compile the Toolkit
2656 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2658 * Fixed a double free in disconnection in the server. Affected
2659 file is silcd/server.c.
2661 * Fixed the lib/silcske/groups.c to work now also with GMP
2662 MP library. The string conversion did not work when using
2663 specific base and the base is indicated in the string as well.
2665 * Created win32/ directory which now includes MSVC++ specific
2666 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2667 It will appear only in the toolkit distribution
2669 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * Changed the key material distribution function in case when
2672 the hash output is too short. The data is now concatenated
2673 a bit differently than it used to. Made the change to the
2674 SKE protocol specification.
2676 * Added better GMP detection to configure.in.pre. A patch
2679 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2681 * Fixed a minor bug in SKE that might cause some problem on
2682 some platforms. Affected file lib/silcske/silcske.c.
2684 * Added the cookie checking for initiator in the SKE. It checks
2685 that the responder returns the sent cookie unmodified. The
2686 affected file is lib/silcske/silcske.c. Added new SKE
2687 error type INVALID_COOKIE that can be sent during the
2688 negotiation. Fixed some memory leaks as well.
2690 * Added the "invalid cookie" error message to Irssi SILC client's
2693 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2695 * Added `task_max' field to the SilcClientParams to indicate
2696 the maximum tasks the scheduler can handle. If set to zero,
2697 default values are used. Affected file lib/silcclient/silcapi.h.
2699 * Fixed memory leaks in silc_client_close_connection. Affected
2700 file lib/silcclient/client.c.
2702 * Added silc_client_del_client_entry to client library to free
2703 all memory of given client entry. Affected file is
2704 lib/silcclient/idlist.[ch].
2706 * Added new functions silc_client_del_channel and
2707 silc_client_del_server to delete channel and server entries.
2708 Affected file lib/silcclient/[silcapi.h/idlist.c].
2710 * Removed silc_client_del_client_by_id from silcapi.h.
2712 * Fixed the INFO command to return the server's own info
2713 correctly when querying by Server ID. Affected file is
2716 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2718 * Removed the non-blocking settings in WIN32 code in the
2719 silc_sock_[read/write] and added SleepEx instead. Affected
2720 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2721 of input data is now checked with FIONREAD and ioctlsocket.
2723 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * Call silc_schedule_task_del_by_context in the
2726 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2727 Affected file lib/silccore/silcprotocol.c.
2729 * Call silc_protocol_cancel for active protocols in the
2730 silc_server_close_connection if the funtion
2731 silc_server_free_sock_user_data has not been called.
2732 Affected file silcd/server.c.
2734 * Generic tasks cannot be deleted using the del_by_fd
2735 task deleting function since generic tasks does not match
2736 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2738 * Added a notion to SILCOPER help file that the SILCOPER works
2739 only on router server, not on normal server.
2741 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Added for WIN32 support for the new scheduler as well.
2744 Affected file lib/silcutil/win32/silcwin32schedule.c.
2746 * Fixed the SHA1 implementation to work on various platforms.
2748 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2750 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2751 API. It is part of the scheduler now. Everything else is
2752 as previously but some functions has changed their names.
2753 Checkout the lib/silcutil/silcschedule.h for the interface.
2754 Updated all applications to use the new interface. Affected
2755 files are lib/silcutil/silcschedule.[ch].
2757 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2759 * Found a bug in the SKE implementation. The HASH value,
2760 specified by the protocol, was not computed correctly. The
2761 public key of the responder was not added to the computation
2762 even though it is mandatory. Affected file lib/silcske/silcske.c.
2763 This unfortunately causes incompatibilities with older
2764 clients and servers.
2766 * Added WIN32 specific network init and uninit functions:
2767 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2768 the Winsock2. Affected file lib/silcutil/silcnet.h and
2769 lib/silcutil/win32/silcwin32net.c.
2771 * Set the socket always to nonblocking mode on WIN32 after
2772 reading data or writing data. Affected file is
2773 lib/silcutil/win32/silcwin32sockconn.c.
2775 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2777 * Fixed various compilation problems under WIN32. Affected
2778 files lib/silcutil/win32/silcwin32thread.c and
2779 lib/silcutil/win32/silcwin32schedule.c.
2781 * Removed all _internal.h #includes from public header
2782 files. Internal headers must never be included from
2785 Removed also the lib/silcske/payload_internal.h file.
2787 * All include files that may be needed (public and some others
2788 included by the public headers) by application developers are
2789 now copied to the ./includes directory. It does not copy any
2790 internal headers. Affected file Makefile.defines.pre and all
2791 Makefile.am's under lib/ and subdirs.
2793 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Do not change the ~/.silc directory's permissions automatically.
2796 Affected file irssi/src/silc/core/clientutil.c.
2798 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2800 * Do not cancel the protocol in silc_server_close_connection
2801 it might cause recursion. Now cancelled in the function
2802 silc_server_free_sock_user_data. Affected file silcd/server.c.
2804 * Fixed the silc_server_remove_clients_by_server to regenerate
2805 the channel keys correctly finally. Added also new function
2806 silc_server_remove_clients_channels to actually do it.
2807 Affected file silcd/server.c.
2809 * Fixed the silc_server_new_channel to not crash by giving
2810 wrong router to the new channel. Affected file is
2811 silcd/packet_receive.c.
2813 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2815 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2816 which is given as argument to the silc_client_alloc now.
2817 It can be used to configure the client and set various parameters
2818 that affect the function of the client.
2820 * The USERS command in server did not check whether the channel
2821 is private or secret. Affected file silcd/command.c.
2823 * Added new argument to the USERS command in protocol specification.
2824 The USERS command now can take the channel name as argument
2825 as well. Added support for this in client and server and
2826 updated the protocol specs.
2828 * Completed the GETKEY command in client. It can be now used
2829 to fetch also servers public key not only some clients.
2830 Affected files lib/silcclient/command[_reply].c.
2832 * Added silc_client_get_server to return server entry by the
2833 server name. Affected files lib/silcclient/silcapi.h and
2836 * Redefined the IDENTIFY command in protocol specification to be
2837 more generic. It now can be used to query information about
2838 any entity in the SILC Network, including clients, servers and
2839 channels. The query may be based either the entity's name
2840 or the ID. Added support for this in both client and server.
2842 Affected files silcd/command.c and lib/silcclient/command.c
2843 and command_reply.c.
2845 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2846 the _from_client and _from_server functions. Affected file
2849 * Added silc_client_get_channel_by_id_resolve to the file
2850 lib/silcclient/silcapi.h to resolve channel information by
2851 its ID. Added also silc_client_get_channel_by_id that
2852 does not resolve it from the server.
2854 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2856 * Added SilcServerEntry context into the client library
2857 to represent one server. The INFO command now allocates
2858 these to save the resolved server info. For now on the
2859 client library will also keep information about servers,
2860 connected and resolved with INFO.
2862 The INFO command now allocates the SilcServerEntry context
2863 and saves the server info there. The COMMAND_REPLY in
2864 the INFO now returns the parameters to application in
2865 same order as defined in the protocol specification.
2867 The entries are cached in the client->server_cache.
2869 * The INFO command is now issued after received the Client ID
2870 from the server. Affected file lib/silcclient/client.c.
2872 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2873 to the application as the mode changer might be server.
2874 It is guaranteed that NULL is not returned anymore to the
2875 application. Affected file lib/silcclient/client_notify.c.
2877 The ID Type is now also passed to the application so that
2878 it can check whether the returned entry is SilcClientEntry
2881 Added new function silc_client_get_server_by_id to return
2882 the server entry by ID. Affected files are the
2883 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2885 * Do not create the channel in the Irssi SILC Client when issuing
2886 the JOIN command but when received the sucessful JOIN command
2887 reply. Otherwise the channel might get created even though we
2888 could not join it. The Affected file is
2889 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2891 * Fixed a channel joining bug in router. The router must also
2892 check the channel modes, invite and ban lists etc. when serving
2893 the JOIN command sent by normal server. Affected file is
2894 silcd/command.c. The router now resolves the client's
2895 information from the server who sent the JOIN command if it
2896 does not know it, and processes the JOIN command only after
2899 * Changed the SilcCommandCb to take new argument; void *context2.
2900 Affected file lib/silccore/silccommand.h
2902 The second argument in the command callbacks in the server now
2903 includes the SilcServerCommandReplyContext if the command was
2904 called as pending command callback from the command reply.
2905 Otherwise it is NULL. When called as pending the status of the
2906 command reply will be checked and if it was erronous the
2907 error will be sent to the original sender of the command.
2908 This way the client always receives the error messages even
2909 though the server was actually the one who received the error
2910 when it resent the command to router, for example. Affected
2911 files silcd/command[_reply].[ch].
2913 * Fixed sending WHOWAS command's error message to client if
2914 the requested client could not be found. It was missing.
2917 * Changed the CMODE and CUMODE commands reply arguments in the
2918 protocol specification. The Channel ID is now sent in both
2919 of the commands to identify the channel. Implemented this
2920 new feature to the client and server. Affected files
2921 lib/silcclient/command_reply.c and silcd/command.c.
2923 * Made better checks for invite and ban lists in the JOIN
2924 command in server. Affected file silcd/command.c.
2926 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2928 * The server now performs the incoming host IP/DNS lookup
2929 using the silc_socket_host_lookup and thus does not block
2930 the server anymore. Affected file silcd/server.c.
2932 * Completed the multi-thread support for SILC Scheduler in
2933 the lib/silcutil/silcschedule.c.
2935 * Fixed the configure.in.pre to detect the pthread correctly
2938 * Fixed a deadlock in silc_task_queue_wakeup in the file
2939 lib/silcutil/silctask.c.
2941 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2943 * Added new function silc_schedule_wakeup that is used in
2944 multi-threaded environment to wakeup the main thread's
2945 schduler. It needs to be used when a thread adds a new task
2946 or removes a task from task queues. After waking up, the
2947 scheduler will detect the task queue changes. If threads
2948 support is not compiled in this function has no effect.
2949 Implemented the wakeup mechanism to both Unix and WIN32
2950 systems. Affected files are lib/silcutil/silcschedule.[ch],
2951 lib/silcutil/unix/silcunixschedule.c and the
2952 lib/silcutil/win32/silcwin32schedule.c.
2954 * Added new function silc_task_queue_wakeup to wakeup the
2955 scheduler by the specified task queue. Affected file
2956 lib/silcutil/silctask.[ch].
2958 * The silc_socket_host_lookup_start now wakes up the scheduler
2959 after adding the timeout task. Affected file is
2960 lib/silcutil/silcsockconn.c.
2962 * The silc_socket_host_lookup is synchronous now if the threads
2963 support is not compiled in. However, the callback is still
2964 called asyncronously through the scheduler, anyway. Affected
2965 file lib/silcutil/silcsockconn.c.
2967 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2969 * Added new function silc_socket_host_lookup to perform
2970 asynchronous IP and FQDN lookups for the socket connection.
2971 Affected files lib/silcutil/silcsockconn.[ch].
2973 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2976 that may or may not compile the mutex support in.
2978 Changed the silc_mutex_alloc interface. It allocates the
2979 mutex now to the sent pointer and returns TRUE or FALSE.
2981 Affected file lib/silcutil/silcmutex.h.
2983 * Wrote the SILC Task Queue interface to support multi-threads.
2984 Affected file lib/silcutil/silctask.[ch].
2986 * Wrote the SILC Scheduler to support multi-threads. Affected
2987 file lib/silcutil/silcschedule.c.
2989 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2991 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2992 in lib/silcutil/win32/.
2994 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2996 * Defined SILC Mutex API and SILC Thread API and implemented
2997 them for Unix. Affected files are
2998 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2999 lib/silcutil/unix/silcunixmutex.c and
3000 lib/silcutil/unix/silcunixthread.c.
3002 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * Fixed the silc_server_remove_clients_by_server's channel
3005 key re-generation. The hash table handling was incorrect
3006 and would not work with many channels. Affected file is
3009 * Fixed some memory leaks around the server code.
3011 * Rewrote the silc_server_get_users_on_channel to support IPv6
3012 based Client ID's. Affected file silcd/server.c.
3014 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3015 specification. However, a separate document must be written
3016 to define the detailed signing procedure and the payload
3017 associated with the flag. Defined the flag to the
3018 lib/silccore/silcchannel.h as well.
3020 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3022 * Changed the dynamic tables to static size tables in the
3023 lib/silccrypt/silchmac.c.
3025 * Removed GCC dependencies from the code. A patch by cras.
3027 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3029 * Do not show the error "Error receiving packet bla bla"
3030 in server if it really was not an error (-2 means that reading
3031 is pending). Affected file silcd/server.c.
3033 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3035 * Fixed a possible crash in silc_server_remove_clients_by_server
3036 in silcd/server.c. Fixed there also some memory leaks.
3038 * Fixed the silc_idlist_replace_client_id. It could replace
3039 wrong key in the hash table. Affected file silcd/idlist.c.
3041 * Do not check whether there are global users on the channel
3042 if the channel->global_users is FALSE. Affected functions
3043 silc_server_remove_from_one_channel and
3044 silc_server_remove_from_channels in silcd/server.c. Also,
3045 do not check if the removed client is local as we can be
3046 sure that global client was not removed from the channel
3047 and checking for global users is not needed.
3049 * The silc_server_remove_clients_by_server now re-generates
3050 the channel keys correctly for those channels that had
3051 clients removed from them. Affected file silcd/server.c.
3053 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3055 * Found the reason of random crashes in the server. We weren't
3056 ignoring the SIGPIPE signal (which can be sent in write())
3057 and it crashed the server. Affected file silcd/silcd.c.
3059 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3061 * Assure that sock->user_data is not NULL in the function
3062 silc_server_packet_send in silcd/packet_send.c.
3064 * Disconnect the remote connection if it could not be added
3065 to any ID lists in the server. The affected file is
3068 * Check in silc_server_packet_send[_real/dest] that the
3069 socket is not disconnecting and ignore the data if it is.
3070 Affected file silcd/packet_send.c.
3072 * Define inline to __inline on native WIN32 compilation.
3073 Affected file includes/silcwin32.h.
3075 * Added some explicit type casts for inline code since MSVC
3076 require them. Affected files lib/silcutil/silcbuffer.h,
3077 lib/trq/silcdlist.h and lib/trq/silclist.h.
3079 * Print warning in log files from now on if the packet
3080 decryption fails. Affected file silcd/server.c.
3082 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3084 * Changed the `say' client operation's interface to accept
3085 new `type' argument to indicate the type of the message sent
3086 by the library. The application may filter the library's
3087 messages according the type. The affected file is the
3088 lib/silcclient/silcapi.h.
3090 * Added two new functions to lib/silcclient/silcapi.h:
3091 silc_client_del_client and silc_client_del_client_by_id.
3092 Affected file lib/silcclient/idlist.c.
3094 * Moved the clientincludes.h from includes/ to silc/ and
3095 serverincludes.h from includes/ to silcd/.
3097 * The modes for the CMODE and CUMODE are now passed as
3098 uint32 for application with COMMAND_REPLY. The affected
3099 file is lib/silcclient/command_reply.c.
3101 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3103 * /WHOIS without arguments shows client's own information.
3104 Affected file lib/silcclient/command.c.
3106 * Changed PING to not accept any arguments. The specs
3107 says that client can ping only the connected server so
3108 requiring an argument is not needed. Affected file is
3109 lib/silcclient/command.c.
3111 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * Fixed a fatal bug in private message sending and reception
3114 encryption and decryption when using private message keys.
3115 The implementation was incorrect and did not follow the
3116 specification. It causd that some of the message were
3117 lost since it did not use the sending and receiving keys
3118 as the protocol suggests. This has been fixed and will cause
3119 incompatibilities with older clients when sending private
3120 message encrypted with private message keys. Affected files
3121 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3122 and various other in Irssi SILC Client.
3124 Added `responder' boolean argument to the functions
3125 silc_client_add_private_message_key[_ske] to indicate when
3126 the key is added as responder or initiator of the key
3129 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3131 * Removed the silc_ske_check_version function and created
3132 a SilcSKECheckVersion callback. Added also a function
3133 silc_ske_set_callbacks that is now used to set all SKE
3134 callbacks. The callback functions are not given to
3135 the SKE functions anymore, but this function is used to
3138 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3140 * Added `silc_version' argument to the silc_client_alloc
3141 to define the version of the application for the library.
3142 The library will use the version string to compare it
3143 against the remote host's (usually a server) version
3144 string. Affected file lib/silcclient/silcapi.h
3146 * Added the KE protocol context to Key Agreement context
3147 in client library so that we can abort the SKE if it
3148 is in process when we get timeout. Affected file is
3149 lib/silcclient/client_keyagr.c.
3151 * Do not resolve the client ID forever if it returns in the
3152 first time that such client does not exist. This was done
3153 for example with private message. Affected file is
3154 lib/silcclient/client_prvmsg.c.
3156 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3158 * Do not add regex.h for WIN32. The affected file
3159 includes/silcincludes.h.
3161 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3162 not work yet 100%. It generates the DLL's automatically
3163 when compiling with --with-win32 under cygwin.
3165 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3167 * lib/contrib/regex.c is not compiled on WIN32.
3169 * Added silc_net_get_socket_opt function to the
3170 lib/silcutil/silcnet.h.
3172 * Added includes/silcwin32.h for WIN32 specific includes
3175 * Do not use ptime structure or any of the posix process
3176 functions on WIN32 in lib/silccrypt/silrng.c.
3178 * Added silc_gettimeofday to provide generic function
3179 for struct timeval on all platforms. Added the function
3180 to lib/silcutil/silcutil.h.
3182 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3184 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3185 library as they clearly belong there. As a plus side we
3186 can make the actual socket connection routines platform
3189 Added also new generic function silc_socket_read and
3190 silc_socket_write (that used to be silc_packet_[read/write].
3191 The implementation of these are platform specific.
3193 * Added WIN32 specific routines of silc_socket_[read/write]
3194 to lib/silcutil/win32/silcwin32sockconn.c.
3196 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3198 * Added preliminary support for native WIN32 compilation under
3199 cygwin (using the -mno-cygwin option for GCC) to the
3200 ./configure.in.pre. The --with-win32 now prepares the
3201 compilation for native WIN32.
3203 * Rewrote the SILC Scheduler interface in the file
3204 lib/silcutil/silcschedule.h. The scheduler is now context
3205 based and does not have anymore any global static scheduler.
3206 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3207 and created lib/silcutil/win32 directory for WIN32 based
3210 * Added Unix specific network routines to the
3211 lib/silcutil/unix/silcunixnet.c and the old
3212 lib/silcutil/silcnet.c includes now only generic routines.
3214 Added WIN32 specific network routines to the
3215 lib/silcutil/win32/silcwin32net.c.
3217 * Added Unix specific utility functions from the
3218 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3220 * Added WIN32 SILC Scheduler to the file
3221 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3224 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3226 * Do not handle JOIN notify in the server if the target client
3227 is not registered (idata->registered == FALSE). The affected
3228 file is silcd/packet_receive.c.
3230 * Update the nickrec->founder in event_cumode in the Irssi SILC
3231 client. Affected file irssi/src/silc/core/silc-channels.c.
3233 * Fixed the CUMODE_CHANGE notify handling in the server when
3234 server and router are announcing their clients on channels.
3235 Now the mode changes are saved and notified correctly. The
3236 affected file is /silcd/packet_receive.c.
3238 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3239 They really did not replace the cache entry in the ID Cache.
3240 Now they do that. Affected file silcd/idlist.c.
3242 * Fixed the KICK notify handling in the Irssi SILC client to
3243 update the channel records so that the kicked client does not
3244 appear to be on the channel. The affected file is
3245 irssi/src/silc/core/silc-channels.c.
3247 * Always update the conn->current_channel when executing command
3248 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3250 * Fixed the KILL notify handling in Irssi SILC client to remove
3251 the killed client on all channels.
3253 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3255 * Fixed the silc_parse_command_line to remove extra spaces
3256 from the start and end of the arguments. Affected file is
3257 lib/silcutil/silcutil.c.
3259 * Cancel and free any active protocol in the function
3260 silc_server_close_connection. Affected file silcd/server.c.
3262 * Cancel and free any active protocol in the function
3263 silc_client_close_connction. Affected file is
3264 lib/silcclient/client.c.
3266 * Do not execute the KILL command for clients that are in
3267 history (ie. they are not in the network). Affected file is
3270 * Fixed KILL notify handling, client does not crash anymore.
3271 Affected file irssi/src/silc/core/silc-channels.c.
3273 * Reduced the default packet buffer size from 2048 to 1024 in
3274 lib/silccore/silcpacket.c.
3276 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3277 counter to the SKE context that is incresed when the SKE library
3278 performs async operation outside the library. If the outside
3279 process frees the SKE context and FREED status will be set
3280 and the library will detect after the sync operation that the
3281 libary is freed. The affected files are
3282 lib/silcske/silcske[_status].[ch].
3284 * Resolve the client entry information in the function
3285 silc_client_channel_message to assure that NULL pointer is not
3286 passed as client entry to the application. */
3288 * Fixed the task timeout calculation to assure that there is
3289 never negative timeouts. The affected file is
3290 lib/silcutil/silcschedule.c.
3292 * Fixed the channel user mode notification sending in server.
3293 It was sent point-to-point to the router (or to server by router)
3294 but it needs to be destined to a channel. The routines now
3295 supports sending the channel user mode notifys to the channels
3296 when announcing clients and channels. Affected files are
3297 silcd/server.c and silcd/packet_receive.c.
3299 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3300 It did not actually replace the old channel entry in the cache.
3301 Affected file lib/silcclient/client_notify.c.
3303 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3305 * Fixed a possible crash in silc_packet_send_prepare. It now
3306 assures always that there is enough space in the buffer and
3307 at the tail area of the buffer (for MAC).
3309 Fixed the inbound buffer reallocation in silc_packet_read.
3310 It was old code and did not handle the reallocation correctly.
3313 The affected file is lib/silccore/silcpacket.c.
3315 * Fixed buffer overflow in silc_parse_nickname in the file
3316 lib/silcutil/silcutil.c.
3318 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * make install generates new server keys only if there is not
3323 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3326 Added check that if the NOREPLY is set then we will not send
3327 the away message. This avoids infinite loop of away messages
3328 if both clients are away. The affected file is
3329 lib/silcclient/client_prvmsg.c.
3331 * Fixed client crash if /NICK was given without arguments.
3332 Affected file lib/silcclient/command.c.
3334 * Server does not send the invite list in INVITE command back
3335 to the client if the list was not altered. Added this notion
3336 to the protocol spec as well. Affected file silcd/command.c.
3338 Fixed possible crash in INVITE command by checking the
3339 value of silc_server_get_client_route command.
3341 * Fixed the INVITE notify type handling. The arguments are now
3342 taken in correct order and client does not crash. The affected
3343 file is irssi/src/silc/core/silc-channels.c.
3345 Removed the "Inviting xxx to channel" message from the
3346 client library away and let the application handle it.
3347 Affected file lib/silcclient/command.c. Added that message
3348 to Irssi SILC client's message formats.
3350 * Fixed CMODE command crash in client. It now checks the
3351 amount of arguments correctly and does not crash. The affected
3352 file is lib/silcclient/command.c.
3354 * Do not create new channel automatically in silc_channels_join
3355 but check whether the channel by that name already exists.
3356 Affected file irssi/silc/core/silc-channels.c.
3358 * Do not send the SERVER_SIGNOFF to router if the disconnected
3359 entity was the router. Affected file silcd/server.c.
3361 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3362 SILC client as it was missing from there.
3364 Added the handling of the KICK notify to the Irssi SILC client
3365 as it was missing. Added "you have been kicked" message to
3366 Irssi SILC client's message modules formats.
3368 Added the handing of the KILL notify to the Irssi SILC client
3369 as it was missing. Added the kill message module formats
3372 The affected file is irssi/src/silc/core/silc-channels.c.
3374 * The router did not save the channel mode the server announced.
3375 Affected file silcd/packet_receive.c.
3377 * Fixed a possible crash in INFO command in server. If the
3378 server did not provide the server info it crashed. Affected
3379 file silcd/command.c.
3381 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Fixed the GETKEY command in the server to check also the
3384 global list. Otherwise the GETKEY would not work correctly
3385 in normal SILC server. Affected file silcd/command.c.
3387 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3389 * Fixed GETKEY crash, it crashed if the command did not succseed.
3391 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3394 is now real and not just an macro interface to GMP.
3396 Removed the entire GMP from the source tree and imported new
3397 NSS MPI library instead. Reason for removing GMP is that it is
3398 extremely large and compiles extremely slow. The NSS MPI
3399 is only a few files and compiles in less than 10 seconds.
3400 The speed is also about the same as GMP. The MPI is imported
3401 to lib/silcmath/mpi.
3403 If the system has GMP installed we will still use the GMP.
3404 If it is not then the NSS MPI will be compiled.
3406 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3408 * Merged a long nickname (127 characters long) crash bugfix from
3409 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3411 * Merged a freed memory reference bugfix from Irssi CVS tree.
3412 Affected file irssi/src/core/commands.c.
3414 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3416 * Added the server's public key sving and verification to the
3417 server when performing the SKE. This was missing and the
3418 remote server's (or router's) public key was accepted without
3419 checking whether we have it previously or trust it at all.
3420 Affected file silcd/protocol.c.
3422 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Check in the silc_server_timeout_remote if protocol is active
3425 and make sure that the protocol's final callback is called so
3426 that all memory if freed. Affected file silcd/server.c.
3428 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * silc_server_whois_send_reply crashed the server if the nickname
3431 was 127 characters long. Affected file silcd/command.c.
3433 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * Added sanity check to the silc_server_new_client. If the hostname
3436 is provided inside username then check that the provided hostname
3437 really is the same as the resolved one. If the hostname was not
3438 resolved then check it from the public key. Affected file is
3439 silcd/packet_receive.c.
3441 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3442 if the server disconnected us and the connection is not valid
3443 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3445 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3446 the library to the lib/silcutil/silcutil.[ch].
3448 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3450 * Close log file after open. Affected file
3451 lib/silcutil/silclog.c.
3453 * Check whether sock == NULL in silc_client_send_packet and return
3454 if it is. Affected file lib/silcclient/silcclient.c.
3456 * Check rec->entry == NULL in the Irssi SILC Client before
3457 sending the channel message. Affecte file is
3458 irssi/src/silc/core/silc-servers.c.
3460 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3462 * Merged a splitted window bugfix from Irssi CVS tree. The
3463 affected file is irssi/src/fe-text/textbuffer-view.c.
3465 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3466 It did not print nickname.
3468 * Improved the distributions system a bit.
3470 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3473 irssi/src/fe-text/gui-window.c.
3475 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3476 to in-active server. The affected file is
3477 irssi/src/silc/core/client_ops.c.
3479 * Resolve the client in USERS command reply if the entry does
3480 not have username resolved. The affected file is
3481 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3482 command to WHOIS command to really resolve stuff. The USERS
3483 is not used any more in any critical section so WHOIS can
3484 be used even though it might be slower than IDENTIFY.
3486 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3489 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Changed the protocol API a bit more consistent in the
3492 lib/silccore/silcprotocol.[ch].
3494 * Changed the following headers to ROBODoc format:
3496 lib/silccore/silcpayload.h
3497 lib/silccore/silcprotocol.h
3498 lib/silccore/silcsockconn.h
3500 All core library headers are now formatted.
3502 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Fixed a bug in Irssi SILC client; do not show that you are
3505 server/router operator if you really are not. Affected file is
3506 irssi/src/silc/core/client_ops.c.
3508 * Renamed silc_command_free_payload to silc_command_payload_free.
3509 Affected file lib/silccore/silccommand.h
3511 * Added silcmath.h to include the prototoypes of various routines
3512 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3515 * Changed the following headers to ROBODoc format:
3517 lib/silccore/silcchannel.h
3518 lib/silccore/silccommand.h
3519 lib/silccore/silcid.h
3520 lib/silccore/silcidcache.h
3521 lib/silccore/silcmode.h
3522 lib/silccore/silcnotify.h
3523 lib/silccore/silcpacket.h
3524 lib/silcmath/silcmath.h
3526 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Added checking to the server code not to start the server if
3529 ciphers and stuff are not configured properly. Affected files
3530 silcd/serverconfig.[h] and silcd/server.c.
3532 * Changed the layout of the header files of the public interfaces
3533 in the SILC libraries. The new layout supports ROBODoc
3534 documentation tool (and some others) so that it is easy to create
3535 a library reference manual. All the other headers and source
3536 code must still follow the CodingStyle document. Also source
3537 code must not include these ROBODoc stuffs, only the headers.
3538 Furthermore, all public interface headers must now be named
3539 by using `silc' prefix, example: silcapi.h, silccipher.h.
3540 Some files were renamed due to this. All the other headers
3541 must not be used as public interfaces. I will update the
3542 CodingStyle document later. Changed following headers, so far:
3544 lib/silcclient/silcapi.h
3545 lib/silccore/silcauth.h
3546 lib/silccore/silcprivate.h
3547 lib/silccrypt/silcdh.h
3549 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3553 * Removed silc_client_packet_send_flush from the client library
3554 as it is not needed. Affected file lib/silcclient/client.[ch].
3556 * Added printing of message of unresolved authentication method
3557 to the Irssi SILC client. Added it to the module formats.
3558 Removed the same message from the client library.
3560 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3562 * Added new distribution feature, DISTLABEL. Every distribution
3563 can define own preprocessor label that can be used in the
3564 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3565 file distributions, acconfig.h.pre and prepare.
3567 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Added Makefile.defines_int to include the actual definitions
3570 for Makefile.defines.in. Tested the new distribution system,
3571 created distributions and tested installation.
3573 * Added AWAY message printing to the Irssi SILC client. Added
3574 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3576 * Added SCONNECT command to call the SILC's CONNECT command.
3577 Cannot use CONNECT directly since Irssi uses that internally.
3578 Affected file irssi/src/silc/core/silc-servers.c.
3580 Added ACTION local command. It is same as ME command but takes
3581 the channel as mandatory argument.
3583 Rewrote some of the Irssi's help files to suite for SILC
3586 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3588 * Added Makefile.defines[.in] that should for now on be included
3589 in all Makefile.am file in the source tree. That file includes
3590 all common compilation definitions for SILC source tree.
3592 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Minor changes to the ./prepare script to change the package
3595 name according the distribution name to the configure.in.
3597 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Created new distribution system. Added file `distributions'
3600 that defines all the distributions that can be created out of
3601 the SILC source tree. The ./prepare script now reads that
3602 file to determine how to prepare the distributions. The
3603 first argument to the ./prepare is the name of the distribution
3604 and second is the version of the distribution. If given
3605 without arguments it creates the default (toolkit) distribution
3606 with the default version (defined in ./prepare).
3608 All Makefile.am files that are subject to the distributions
3609 are now named as Makefile.am.pre. These are ./Makefile.am
3610 and lib/Makefile.am. Others may be changed later.
3612 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Added invite list, ban list, some key management and connection
3615 error message printing to module formats in the Irssi SILC client.
3617 * Added new silc_client_set_away_message to set the away message
3618 that is back to the person who sent private message. The
3619 affected file lib/silcclient/silcapi.h and the
3620 lib/silcclient/client_prvmsg.c.
3622 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Fixed the private message sending in the Irssi SILC client,
3625 added local command KEY to the Irssi SILC client.
3627 Added key management and key agreement message formats to the
3628 irssi/src/fe-common/silc/module-formats.[ch].
3630 Added USERS (alias WHO) printing, server/router operator
3631 indication and LIST command printing to the module formats.
3633 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Fixed channel joining notify handling, cumode notify handling
3636 from Irssi SILC client.
3638 * Added SILC specific module-formats to the Irssi SILC client so
3639 that SILC specific message hilighting, colors etc is possible.
3640 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3642 Added channel mode, channel user mode, actions, notices,
3643 whois and whowas printing to the the module-formats.c.
3645 * Fixed a bug in channel deletion in the server. The channel
3646 is not left to the cache even if the channel founder auth mode
3647 is set when there are no users anymore on the channel. Affected
3648 file silcd/server.c.
3650 * The silc_net_localhost now resolves the entire hostname including
3651 the domain name. Affected file lib/silcutil/silcnet.c.
3653 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Changed the ask_passphrase client operation to be ascynchronous.
3656 It has now a completion callback and a context that the
3657 application must call after it has got the passphrase from
3658 the user. Affected files lib/silcclient/silcapi.h,
3659 lib/silcclient/protocol.c, lib/silcclient/command.c and
3662 Added SilcAskPassphrase callback that the application calls
3663 to deliver the passphrase to the library.
3665 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3666 The public key verification and especially a certificate
3667 verification is asynchronous procedure.
3669 Added new SILC_SKE_STATUS_PENDING status to indicate the
3670 request is pending and a callback will be called to finalize
3673 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3674 indicate that remote end did not send its public key (or
3675 certificate), even though we require it. Added check for this
3676 condition in the SKE. This was a security bug, now fixed.
3678 Defined new SilcSKEVerifyCbCompletion callback that is called
3679 when the verification process is completed.
3681 The affected files lib/silcske/silcske_status.h and
3682 lib/silcske/silcske.[ch].
3684 * Changed the verify_public_key client operation to be async
3685 as well. Defined SilcVerifyPublicKey callback that is used to
3686 indicate the success of the public key verification process.
3688 Changed the server and client to use the new async client
3691 * Changed the Irssi SILC client's internal scheduler to be called
3692 twice as many times as it used to be. As a result the client
3693 should be a bit faster now. Affected file is
3694 irssi/src/silc/core/silc-core.c.
3696 * Added support to Irssi SILC client of asynchronous public key
3697 verification and passphrase inquiry. Affected file is
3698 irssi/src/silc/core/silc-core.c.
3700 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Do not say "You have left channel %s" in client library.
3703 Moved it to the application. Affected files are
3704 lib/silcclient/command.c and silc/client_ops.c.
3706 * Fixed silc_client_get_clients. Command context was not
3707 duplicated and was freed memory in the callback. Affected
3708 file lib/silcclient/idlist.c.
3710 * Do not say "you are now talking..." on JOIN command in the
3711 client library. The appliation must handle it.
3713 * Do not say ".. changed topic to" in command reply in the
3714 client libary. The application must handle it.
3716 * Fixed TOPIC command sending in the client library.
3718 * Fixed a memory leak in silc_client_command_free in the file
3719 lib/silcclient/command.c.
3721 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * Imported a modified version of Irssi client to the source tree.
3724 The Irssi will be used to create a new client called
3725 Irssi SILC. Imported to irssi/.
3727 Added silc_core_init_finish function to the Irssi. Affected
3728 file irssi/configure.in.
3730 A lot changes in the Makefile.ams around the irssi tree.
3732 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Do not rehash if the new size is same as the old size of the
3735 hash table, in the silc_hash_table_rehash*. The affected file
3736 lib/silcutil/silchashtable.c.
3738 * Replaced hash_table_del_by_context calls from the server
3739 (when channel->user_list and client->channels) to the
3740 hash_table_del as it is sufficient and faster.
3742 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Added silc_hash_table_list, silc_hash_table_get and the
3745 SilcHashTableList structure to provide an alternative way to
3746 traverse the hash table. The affected files are
3747 lib/silcutil/silchashtable.[ch].
3749 * Changed the server's idlist routines to use the hash table
3750 routines to optimize the code.
3752 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Replaced the client entry's `channel' list and channel entry's
3755 `user_list' list to hash tables for optimized lookup. Changed
3756 the code to use the hash table interface around the code.
3757 Affected file lib/silcd/idlist.[ch].
3759 * Added `auto_rehash' boolean argument to the function
3760 silc_hash_table_alloc to indicate whether the hash table should
3761 auto-rehash when it thinks is appropriate time. It will
3762 increase the hash table size if the there is twice as much
3763 entries in the table than the size of the table, and will
3764 decrease the size if there are twice as less entries than
3765 the size of the table.
3767 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3771 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3773 * silc_idcache_purge_by_context deletes the entry now by context
3774 as it is supposed to do. Affected file lib/silccore/idcache.c.
3776 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3777 client is not anymore valid (WHOWAS givens the info) and not
3778 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3780 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3782 * Removed the `data' and `data_len' arguments from the ID Cache
3783 interfaces and added `name' argument. ID Cache does not handle
3784 anymore the binary data only a names associated with given ID.
3786 * When hashing a Client ID with silc_hash_id the entire ID is
3787 not hashed anymore, instead only the hash of the Client ID is
3788 hashed. This way we can access the Client ID from the cache
3789 with Client ID but with the hash of the ID (which is a hash of
3790 the nickname) as well without any difference in performance.
3792 Added also silc_idcache_find_by_id_one_ext to do one on one
3793 searching when we have the actual ID. Added also function
3794 silc_hash_client_id_compare. The affected files are
3795 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3797 * When hashing the name associated with a ID it is always done
3798 in lowercase. This way we can access the cache without worrying
3799 about case-sensitivity, even though, for example nicknames are
3802 * Fixed a bug in server with channel message sending. It put
3803 wrong ID type as destination ID. The affected file
3804 silcd/packet_send.c.
3806 * silc_idcache_del_by_context now deletes from all hash tables
3807 by context. Affected file lib/silccore/idcache.c.
3809 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Changed the client library to use the new ID Cache interface.
3812 Changes around the source tree.
3814 * Added silc_hash_table_rehash_ext to rehash with specific
3815 hash function. Affected file lib/silcutil/silchashtable.[ch].
3817 * Added silc_hash_string_compare to compare two strings in the
3818 hash table. Affected file lib/silcutil/silcutil.[ch].
3820 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Added new function silc_idcache_del_by_context into the
3823 lib/silccore/idcache.[ch].
3825 * Changed the server's ID list routines to use the new ID Cache
3826 interface. Changes around the source tree.
3828 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * Added silc_hash_table_del[_by_context]_ext functions in to the
3831 lib/silcutil/silchashtable.[ch].
3833 Removed silc_hash_table_find_all* routines and added new
3834 silc_hash_table_find_foreach to replace them.
3836 Added silc_hash_table_replace_ext function as extended
3837 replacing function. Separated the simple hash table interface
3838 from the extended hash table interface in the file
3839 lib/silcutil/silchashtable.h.
3841 * Fixed minor bugs and changed it to use some of the new
3842 hash table functions in lib/silccore/idcache.c
3844 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * Added new function silc_hash_table_find_all to return all keys
3847 in the hash table by the specified key. As the hash table is
3848 collision resistant it also makes it possible to have several
3849 duplicate keys in the hash table. This function may be used to
3850 find all of the keys from the hash.
3852 Added user_context arguments to the SilcHashFunction,
3853 SilcHashCompare and SilcHashDestructor to deliver user specified
3856 Added new fuctions silc_hash_table_find[_all]_ext to do
3857 extended lookup with specified hash and compare functions and
3858 specified user contexts.
3860 Added new function silc_hash_table_add_ext to add the key
3861 with specified hash function and user context.
3863 Added new function silc_hash_table_foreach to traverse all
3864 entrys in the hash table. Added SilcHashForeach callback
3867 Added new function silc_hash_table_del_by_context to delete
3868 the entry only if the context associated with the key matches.
3870 Affected files are lib/silcutil/silchashtable.[ch].
3872 * Removed silc_hash_[server/client/channel]_id and added just
3873 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3874 silc_hash_id_compare to compare two ID's using as the hash table
3875 comparison function. Added also silc_hash_data to hash
3876 binary data and silc_hash_data_compare to compare it.
3878 * Removed silc_idlist_find_client_by_hash as it is not needed
3879 anymore. Affected file silcd/idlist.[ch].
3881 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3882 to use internally the SilcHashTable. The new ID Cache is a lot
3883 faster than the old one. Some of the ID Cache interface was also
3884 rewritten and obsolete and stupid functions were removed.
3886 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Added entry_count field to the SilcHashTable to keep the number
3889 of the entries in the table. Implemented the function
3890 silc_hash_table_rehash. Added new function
3891 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3893 Fixed a minor bug in silc_hash_table_free.
3895 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3896 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3897 into the lib/silcutil/silcutil.[ch].
3899 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3901 * Implemented a collision resistant hash table into the
3902 lib/silcutil/silchashtable[ch]. See the header and the source
3903 for the SilcHashTable API.
3905 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3907 * Merged dotconf version 1.0.2 into lib/dotconf.
3909 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * Do not compile anything in lib/silcsim/* if the SIM support
3912 is not enabled. The tree should now compile without problems
3915 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Compiled the SILC under cygwin. Compiled and tested briefly
3918 without problems. More tests needed. The SIMs didn't compile
3921 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3923 * Fixed possible crash in silc_get_username in the
3924 lib/silcutil/silcutil.c.
3926 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3928 * Fixed a va_arg in silc/client_ops.c.
3930 * Oops, RC5 routines were named AES and caused some problems
3931 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3933 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Added new SilcIDIP structure into the lib/silccore/id.h and
3936 replaced the old `ip' fields from all SILC ID's to that type.
3937 This is a step towards IPv6 support.
3939 The silc_id_get_len takes now the ID as an extra argument.
3940 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3941 both IPv4 and IPv6 based ID's.
3943 The affected files are lib/silccore/id.[ch] and other files
3944 around the tree using these routines.
3946 * Removed the ID length arguments in server from various
3947 silc_server_send_notify_* routines -> they are not needed
3950 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Fixed memory leak in silc_encode_pem_file in the file
3953 lib/silcutil/silcutil.c.
3955 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Check minor version as well in the SKE. Affected files are
3958 silcd/protocol.c and lib/silcclient/protocol.c.
3960 * Added --identifier option to the server so that an identifier
3961 can be when creating the public key for the server. Affected
3962 file is silcd/silcd.c.
3964 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3965 lib/silccrypt/silcpkcs.c.
3967 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Register default ciphers and stuff when using -C option with
3970 the server. Affected file sildc/silcd.c.
3972 * Put back the servers public key filename format, it is better
3973 than the new one. For now, the client keys are saved with the
3974 new filename format. The affected file silc/client_ops.c.
3976 * Implemented the Cipher API for the rest of the ciphers that
3977 did not implement it or implemented it the wrong way.
3979 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Register default ciphers and stuff when using the -S option
3982 in the client. Affected file silc/silc.c. Same also when
3983 creating new key pair with -C option.
3985 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Fixed the silc_verify_public_key client operation function to
3988 save the public keys differently. The fingerprint is now
3989 used as filename and not the hostname. This way also the
3990 client keys are saved uniquely and not with hostnames. The
3991 affected file is silc/client_ops.c.
3993 * Trimmed the silc_hash_fingerprint function to remove extra
3994 whitespaces from the end of the fingerprint. The affected
3995 file is lib/silccrypt/silchash.c.
3999 * Added silc_cipher_register_default function to register all
4000 default ciphers. It can be used when configuration files
4001 does not exist and the application does not want any specific
4002 ciphers in any specific order.
4004 The SilcDList is now used as silc_cipher_list dynamically
4005 allocated cipher list. Removed the static list all together
4006 and now all ciphers must be allocated to the dynamic list.
4007 The silc_cipher_alloc routine was changed to check only the
4010 All silc_cipher_* routines that used to return int returns
4013 The affected files lib/silccrypt/silccrypt.[ch].
4015 * The same thing was done to silc_hash_* as for silc_cipher_*
4016 routines. Affected files lib/silccrypt/silchash.[ch].
4018 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4019 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4020 Added also silc_pkcs_[un]register[_default] functions.
4021 Removed the data_context from the PKCS API.
4023 * Added silc_hmac_register_default function to register default
4024 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4025 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4026 to unregister all hmacs at once.
4028 * Register the default ciphers, hash functions, PKCSs and HMACs
4029 if client's configuration file does not exist. The affected
4032 * The client did not load the hash functions from the SIM
4033 modules at all. Added support for this. Affected file is
4034 silc/clientconfig.c.
4036 * When decoding public key with silc_pkcs_public_key_decode, check
4037 the supported algorithm only if PKCS are registered. Affected
4038 file lib/silccrypt/silcpkcs.c. The same was done with the
4039 silc_pkcs_private_key_decode.
4041 * Fixed the SILC List routines to keep the list always in order.
4042 It used to change the list's order when traversing the list but
4043 not it preserves the order. Affected file lib/trq/silclist.h.
4045 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Added the client library to use the SilcSocketConnection's
4048 reference counter (by silc_socket_dup) to prevent the bug that
4049 the socket object may be freed underneath async operation.
4051 * The name resolv library checking fixes in the configure.in.pre.
4054 * Created new version of the protocol drafts for future
4055 development. The -03 drafts are the ones that will be changed
4056 in the trunk now and the -02 will remain as they are.
4058 * Send list of CUMODE notifys to the router when announcing
4059 the channel users to the router. Affected file silcd/server.c.
4060 If the router receiving channel founder CUMODE for a channel
4061 that already has channel founder it will send CUMODE notify
4062 to the sender to remove the channel founder rights from the
4063 announced client. Affected file silcd/packet_receive.c.
4065 * The CUMODE notify may now use Server ID as well as the entity
4066 who changes the mode. Updated protocool specs.
4068 * Updated INSTALL and README files.
4070 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4072 * New web pages in the http://silc.pspt.fi. The pages was
4077 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Implemented the [DenyConnectin] config section in the server.
4080 Added silc_server_config_denied_conn to check whether incoming
4081 connection is denied. Affected file silcd/serverconfig.[ch].
4083 * Do not check the ports when checking the incoming configuration
4084 data if the port is 0, meaning any. Affected file is
4085 silcd/serverconfig.c.
4087 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Fixed buffer overflow in silc_string_compare in the file
4090 lib/silcutil/silcutil.c.
4092 * Fixed double free in silc_server_command_leave in the file
4095 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4097 * Fixed the version checking in the server. Affected file is
4100 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4102 * Fixed the configuration data fetching when accepting new
4103 connections in the server. Affected file silcd/server.c.
4105 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4107 * Added `sender_entry' argument to the function
4108 silc_server_packet_relay_to_channel so that we can check
4109 whether some destination actually belongs to the same route
4110 the sender belongs (ie, we must not resend the packet to the
4111 sender). Affected file silcd/packet_send.[ch].
4113 * Added `servername' field to the SilcClientEntry in the server
4114 to hold the name of the server where client is from. Affected
4115 file is silcd/idlist.h.
4117 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Moved the channel message encrypting in the router betwen
4120 router connections from silc_server_channel_message to the
4121 silc_server_packet_relay_to_channel since we want to check
4122 whether we have anybody channel before encrypting anything.
4123 Affected files silcd/packet_[receive/send].c.
4125 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4127 * Fixed the [AdminConnection] server config section to support
4128 multiple entries. Affected file silcd/serverconfig.c.
4130 * Added support into the server to check the validity of the
4131 incoming connection before executing any KE or authentication
4134 * The connection configuration is now saved to the KE and
4135 connection auth protocol contexts and not fetched anymore in
4136 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4138 * The local hosts listenning address and port is also resolved
4139 now when starting the server. We want to have the socket object
4140 to include the real address and port for the listener. Added
4141 new function silc_net_check_local_by_sock into the files
4142 lib/silcutil/silcnet.[ch].
4144 * Fixed a broadcast bug in server -> do not broadcast if we
4147 * Fixed a routing bug. Do not route broadcast packets ever.
4148 Broadcast packets must be processed always and not routed since
4149 they may be destined to some other host than yourself and thus
4150 would get routed without no good reason. Affected file is
4153 * Added function silc_server_config_is_primary_route to check
4154 whether primary router connection has been configured (a router
4155 configuration that we are initiating). If there is not, we
4156 will assume that there is only two routers in the SILC network
4157 and we will use the incoming router connection as our primary
4158 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4160 * Changed the order of the broadcasting. Broadcast _after_ the
4161 packet has been processed not before. Affected file is
4164 * Fixed a [ClientConnection] parsing bug. The port was never
4165 parsed correctly thus resulting to port 0. Affected file
4166 silcd/serverconfig.c.
4168 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4169 argument and did not set the broadcast packet flag. Affected
4170 file silcd/packet_send.c. Fixed same bug in the function
4171 silc_server_send_notify as well.
4173 * If we receive NEW_ID packet for our own ID in the server, ignore
4176 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Removed the nickname from the Private Message Payload.
4181 Updated the code and the protocol specs.
4183 * Updated protocol specs for submitting to the IETF.
4185 * Tweaked the Random Number Generator a bit. Affected file
4186 lib/silccrypt/silcrng.c. Exported a new function
4187 silc_rng_[global]_add_noise which can be used to add more
4190 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Do not parse packets with different timeout when protocol
4193 is active -> may cause problem with rekey. Affected file
4196 * When server receives signoff notify it must not create
4197 new channel key if the client is on any channels since the
4198 sender of the signoff notify will create it.
4200 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Added printing of error messages during SKE protocol from the
4203 failure packet sent by server during SKE. Affected file
4206 * Removed the client's failure_callback handling with timeout
4207 and handle it immediately when received.
4209 * The SKE library returned wrong type in SUCCESS and FAILURE
4210 packets. They must be 32 bit MSB not 16 bit MSB.
4212 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Ok, rewrote the logic of the re-key and now it seems to work.
4215 I tested it on high traffic with frequent re-keys without
4216 problems. Added hmac_receive (and renamed hmac to hmac_send)
4217 in SilcClientConnection in lib/silcclient/client.h and
4218 in SilcIDListData in silcd/idlist.h. Also, removed the
4219 SilcPacketParserContext's cipher and hmac fields as they are
4220 not needed anymore and actually caused some problems when
4221 the ciphers and hmac's changed underneath the packet parser.
4223 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * If re-key protocol is active then process the incoming packets
4226 synchronously since we must assure that icoming packets encrypted
4227 with the old key is processed before the new keys is set to
4228 use. This is true other packets than for REKEY packets.
4229 Affected file silcd/server.c. The same was done to client library
4230 as well, affected file lib/silcclient/client.c.
4232 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * Fixed bug in client and server to accept the force send if
4235 the packet is send from silc_[server/client]_packet_process
4236 function. Otherwise the packets are never delivered, oops.
4238 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4240 * Disable force sending of packets when REKEY protocol is active.
4241 We must assure that no packet is sent directly when rekey is
4242 performed. All packets must be sent through packet queue.
4243 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4244 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4245 function is silc_[server/client]_packet_send_real to check
4248 * Replaced the SIM paths from example config files to
4249 /usr/local/modules. Also, make install creates now
4250 /usr/local/silc/logs directory to hold all the SILC server
4253 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4255 * Made the configure.in.pre work on Solaris. Patch by salo.

4264 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * When MAC computation fails the silc_packet_decrypt returned 0
4267 even though it was supposed to return -1. Fixed this. The
4268 affected file is lib/silccore/silcpacket.c.
4270 * Do not replace the config files in /etc/silc (in make install)
4271 if they already exist. Affected file ./Makefile.am.
4273 * Do not send re-key packets immediately but through packet queue.
4274 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4276 * Changed silc_net_check_host_by_sock to return FALSE if the
4277 IP/DNS could not be resolved. Though, it returns the IP address
4278 now even if it could not resolve it (but returns also FALSE).
4279 Affected file lib/silcutil/silcnet.[ch].
4281 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Added silc_pkcs_decode_identifier to decode the public key's
4284 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4285 Added also silc_pkcs_free_identifier. Added also new context
4286 SilcPublicKeyIdentifier.
4288 * Added -S option to the silc client. It is used to dump the
4289 contents of the specified public key file.
4291 * Changed the PKCS api to return the public key length when
4292 setting the public key.
4294 * Fixed a fatal bug in the public and private key file loading.
4295 Affected file lib/silccrypt/silcpkcs.c.
4297 * Execute the packet parsing for client with zero (0) timeout
4298 if the protocol is active. Affected file silcd/server.c.
4300 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Made the key generation options to the silcd program. Added
4303 -C option, equivalent to client's option.
4305 * Added new [ServerKeys] config section to the server. It
4306 configures the server's public and private key.
4308 * Defined generic Public Key Payload into the protocol
4309 specification to send specific type of public keys and
4312 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4313 public key or certificate.
4315 * Implemented the GETKEY command to the server and to the
4316 client library and on user interface.
4318 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4320 * Made preliminary `make install' work.
4322 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Added SilcServerRekey context into silcd/idlist.h.
4326 * Added the PFS support as defined in the specification to the
4327 SKE protocol. Affected files lib/silcske/*.c.
4329 * Added `ske_group' field to the SilcServerRekey context to hold
4330 the number of the SKE group that is used with PFS in re-key.
4331 Affected file silcd/idlist.h.
4333 * Added PFS re-key support to the server. Affected file is
4336 * Added silc_protocol_cancel to cancel execution of the next
4337 state of the protocol. Affected file is
4338 lib/silccore/silcprotocol.[ch].
4340 * Added the re-key support with and without PFS to the client
4341 library. Re-key is performed once in an hour, by default.
4343 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4344 Added silc_client_rekey_callback and silc_client_rekey_final.
4345 Affected files are lib/silcclient/protocol.[ch] and
4346 lib/silcclient/client.[ch].
4348 * Removed the `hmac_key' and `hmac_key_len' fields from the
4349 SilcClientConnection structure; not needed. Affected file is
4350 lib/silcclient/client.h.
4354 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Do not ask whether user wants to use the negotiated private key
4357 for private messages, just use it. Affected file is
4358 silc/local_command.c.
4360 * Added `send_enc_key' and `enc_key_len' fields to the
4361 SilcIDListData structure since they are needed in the re-key
4362 phase. Affected file is silcd/idlist.[ch].
4364 * Implemented the simple re-key protocol into the server.
4365 Affected files silcd/server.c and silcd/protocol.[ch]. The
4366 re-key will be performed once in an hour, by default.
4368 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4369 Added silc_server_rekey, silc_server_rekey_callback and
4370 silc_server_rekey_final.
4372 * Removed Tunneled flag from the protocol. Updated the code
4373 and the specifications.
4375 * Adde `pfs' field to the SilcIDListData to indicate whether
4376 the PFS is to be performed in the re-key. Affected file is
4379 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4382 int64 of at least the xintXX size. If void * is less that 4
4383 bytes uint32 * will be used. Defined bool as boolean.
4385 * Changed _ALL_ unsigned long and unsigned int to uint32,
4386 unsgined short to uint16 in the source tree.
4388 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4389 not handle clients that has entry->data.registered == FALSE.
4390 They are not in the network anymore. Affected file is
4393 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Implemented the sending of the SERVER_SIGNOFF notify in the
4396 server. Affected file is silcd/server.c.
4398 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4399 Added also silc_notify_payload_encode_args into the
4400 lib/silccore/silcnotify.[ch].
4402 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4403 Affected file silcd/packet_receive.c.
4405 * Implemented the SERVER_SIGNOFF notify handling in the client
4406 library. Affected file lib/silcclient/client_notify.c. Also,
4407 implemnted the printing of the SERVER_SIGNOFF info to the
4408 application. Affected file silc/client_ops.c.
4410 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4411 if the deleting was successful. Affected file silcd/idlist.[ch].
4413 * Added support for public key authentication in the connection
4414 authentication protocol in the client library. Affected file
4415 lib/silcclient/protocol.c.
4417 * Changed the server's silc_idlist_get_clients_by_* interface
4418 to support already allocated array so that new entries may be
4419 added to pre-allocated array. Affected file silcd/idlist.[ch].
4420 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4421 and command replies.
4423 * All command reply functions in the server now calls the
4424 pending command callback even if error occured. This way the
4425 error will be delivered to the client as well. Affected files
4426 silcd/command.c and silcd/command_reply.c.
4428 * Fixed INFO command to return local server's info if no server
4429 was provided. Affected file lib/silcclient/command.c.
4431 * Removed RESTART command for good. Updated the code and the
4434 * Rewrote parts of the task system. It is a bit simpler now.
4435 Removed unsued task priorities. The affected files are
4436 lib/silcutil/silctask.[ch].
4438 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * Moved the USERS printing from the library to the application.
4441 Affected files lib/silcclient/command.c and silc/client_ops.c.
4443 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4447 * Added channel key re-key support. The re-key is perfomed
4448 only by the router and is done once in an hour. Added `rekey'
4449 field to the SilcChannelEntry in the server. Affected files
4450 silcd/server.c and silcd/idlist.h.
4452 * Added silc_task_unregister_by_context into the file
4453 lib/silcutil/silctask.[ch].
4455 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * Added SILC_UMODE_GONE mode to indicate when the client is not
4458 present in the SILC network. Added also support to the local
4459 command AWAY that will set this mode. Added support of showing
4460 "xxx is gone" in WHOIS command. The USERS command shows the
4461 gone status as well.
4463 * Fixed setting server and router operator privileges in the
4464 server's UMODE command. Affected file silcd/command.c.
4466 * Merged the SKE KE1 and KE2 payloads into one payload. The
4467 new KE payload is equivalent to the old KE2 payload.
4469 Cleaned up the SKE Start Payload parsing. It now uses the
4470 simple buffer unformatting to do the parsing. A lot faster
4473 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4474 to the SKE that is used to indicate whether both of the SKE
4475 parties should perform authentication. By default only the
4476 responder performs authentication. By setting this flag also
4477 the initiator must do authentication. By default it is unset
4478 since in normal SKE case, client to server connection, only
4479 the responder should do authentication. When doing SKE between
4480 two clients both should perform authentication. Updated the
4481 code and the protocol specs.
4483 * A little fix to IDENTIFY command in the server. Search the
4484 client first by hash not nickname. Affected file is
4487 * Fixed the silc_client_close_connection to support closing
4488 the client to client connections wihtout deleting too much
4489 data. Affected file lib/silcclient/client.c.
4491 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4492 are received if protocol used to be active but is not anymore
4493 the application would crash due to NULL pointer dereference.
4494 Affected files silcd/server.c and lib/silcclient/client.c.
4496 * Added `hash' field to the SilcClientConnection to include
4497 the hash function negotiated in the SKE protocol.
4499 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4500 to set the channel founder authentication data. A client can
4501 claim the founder rights later by providing the authentication
4502 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4503 This way the channel founder can regain the channel founder
4504 privileges even it is left the channel. This works only on
4505 local server and the client must be connected to the same
4506 server to be able to regain the founder rights. Updated the
4507 protocol specs accordingly.
4509 Added support to the CMODE command in the client to set the
4510 founder auth data. Read the README to see how to set it.
4512 Added support to the CUMODE command to claim the founder
4513 rights. Read the README to see how to do it.
4515 Added support for the founder authentication to the Channel
4516 Entry in the server. Affected file silcd/idlist.h.
4518 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4519 server's CMODE command. Affected file silcd/command.c.
4521 * Added the following new functions into lib/silccore/silcauth.[ch]:
4522 silc_auth_get_method and silc_auth_get_data.
4524 * The server now saves the remote hosts public key to the
4525 SilcIDListData pointer. Affected file silcd/protocol.c.
4527 * The normal server now does not remove the channel entry from
4528 the cache if the founder authentication data is set. It used
4529 to remove it if the founder was the last one on the channel on
4530 the server and left the channel. The auth data is saved and
4531 if the channel is re-joined later the old entry is used with
4532 the old auth data. Affected files silcd/command_reply.c and
4535 * Removed the `pkcs' field from the SilcIDListData structure
4536 in the server; it is not used. Affected file silcd/idlist.h.
4538 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4540 * Fixed packet processing on slow links. Partial packets were
4541 never re-processed because the incoming data buffer was cleared
4542 by the application. Application must not directly clear the
4543 sock->inbuf, the packet processing routines handle it. Fixed
4544 this in client library and in server.
4546 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Fixed the WHOIS and IDENTIFY send reply function to really
4549 check whether to send list or just one entry. Affected file
4552 * Cleaned up the LEAVE command's channel key distribution. The
4553 affected file silcd/command.c.
4555 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4556 can enforce the channel mode as well. In that case the ID
4557 includes the ID of the server. The code now enforces the
4558 mode change if the router have different mode than the server.
4560 * The notify client operation with CMODE_CHANGE notify can now
4561 return NULL client_entry pointer if the CMODE was not changed
4562 by client. Application must check for this.
4564 * Added <Server ID> argument to INFO command to support server
4565 info fetching by Server ID.
4567 * Added silc_server_announce_get_channel_users to get assembled
4568 packets of channel users of the specified channel. Affected
4569 file silcd/server.[ch].
4571 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4572 was freed underneath the ID Cache.
4574 * Re-announce clients when the server received CHANNEL_CHANGE
4575 notify from the router. Affected file silcd/packet_send.c.
4577 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4580 crashed since it did not handle the fact that there is no cipher
4581 called "3" and didn't check the error condition. Now fixed.
4583 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4584 flag. It can be used to send message requests.
4586 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Implemented the RESTART command in the client.
4590 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4591 notice type messages. Added notice printing to the user
4594 * The channel keys are not re-generated if the channel's mode
4595 is PRIVKEY, ie private key on the channel exists. Affected
4596 files silcd/server.c and silcd/command.c.
4598 * Fixed a little bug in channel message delivery when channel
4599 private keys are set in the server. Affected file is
4600 silcd/packet_send.c.
4602 * Changed the setting on channel->on_channel = TRUE from the
4603 silc_client_save_channel_key to the JOIN command reply. The
4604 key payload is not received if the private channel key is set.
4605 Affected file lib/silcclient/command_reply.c and the
4606 lib/silcclient/client_channel.c.
4608 * When the CMODE_CHANGE notify is sent and the channel private
4609 key mode is removed the channel key must be re-generated in
4610 other cells as well. Added this support for the router in the
4611 silcd/packet_receive.c.
4613 * Added new local command NOTICE to send notice message on
4614 channel. Affected file silc/local_command.[ch].
4616 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Added new local command ME to the client. It is used to send
4619 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4620 some action. Affected file silc/local_command.[ch].
4622 * Changed channel_message and private_message client operations
4623 to deliver the message flags to the application. Added also
4624 the `flags' arguments to the silc_client_send_channel_message
4625 and silc_client_send_private_message functions. Affected file
4628 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4630 * Redefined the Private Message Payload to support private message
4631 keys and to support the new private message flags. Updated
4632 the protocol specs. Flags makes it possible to have for example
4633 CTCP style messages.
4635 * Added new type SilcPrivateMessagePayload and defined an API
4636 for it in the lib/silcclient/silcprivate.[ch].
4638 * Tested private message private keys successfully. Tested the
4639 private message key set, unset and list commands with the new
4642 * Redefined the Channel Message Payload to include the channel
4643 message flags (equal with private message flags) to support
4644 for example CTCP style messages.
4646 * Defined some of the message (for channel and private message)
4647 flags. Updated the protocol specs and added the flags to the
4648 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4650 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Added SilcKeyAgreementStatus type to the key agreement routines
4653 to indicate the current status and error if one occured.
4654 The status types are defined in the lib/silcclient/silcapi.h.
4656 * Added new local command KEY that is used to set and unset private
4657 keys for channels, set and unset private keys for private messages
4658 with remote clients and to send key agreement requests and
4659 negotiate the key agreement protocol with remote client. The
4660 key agreement is supported only to negotiate private message keys,
4661 it currently cannot be used to negotiate private keys for channels,
4662 as it is not convenient for that purpose.
4664 * Fixed a minor pending callback setting bug in the function
4665 silc_client_get_client_by_id_resolve, now the function works.
4666 Affected file lib/silcclient/idlist.c.
4668 * Added function silc_net_get_local_port to get local bound
4669 port by socket. Added to lib/silcutil/silcnet.[ch].
4671 * Added `sockets' and `sockets_count' fields to the SilcClient
4672 object. They hold the sockets of the listenning sockets in
4673 the client. Listenning sockets may be for example the key
4674 agreement server. Affected file lib/silcclient/client.[ch].
4675 Added functions the silc_client_add_socket and the
4676 silc_client_del_socket. They are exported to the application
4679 * Added ~./silc/clientkeys to support other client's public keys.
4681 * Renamed verify_server_key client operation to verify_public_key
4682 and added one argument to indicate the type of the connection
4683 (server, client etc.).
4685 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4687 * Added silc_server_connection_auth_request to handle the
4688 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4689 silcd/packet_receive.[ch].
4691 * Added silc_server_send_connection_auth_request into the
4692 silcd/packet_send.c to send the connection auth request packet.
4694 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4697 * Fixed the public key authentication in responder side in the
4698 server. The `auth_data' pointer includes the SilcPublicKey
4699 not the path to the public key. Affected file silcd/protocol.c.
4701 * Implemented the public key authentication in the initiator side
4702 in the server. Affected file silcd/protocol.c.
4704 * Removed the [RedirectClient] config section from the server
4705 configuration. Is not needed and I don't want to implement it.
4707 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Cleaned up the CMODE command in the server. It now works
4710 correctly and supports all the modes defined in the protocol.
4711 Affected file is silcd/command.c.
4713 * Added `hmac_name' field to the SilcChannelEntry in the server
4714 to hold the default HMAC of the channel. It can be set when
4715 creating the channel (with JOIN command). Affected files
4718 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4719 type to indicate the change of the current cipher and hmac
4720 on the channel. Client can safely ignore the <cipher> argument
4721 (if it chooses to do so) since the CHANNEL_KEY packet will
4722 force the channel key change anyway. The <hmac> argument is
4723 important since the client is responsible of setting the new
4724 HMAC and the hmac key into use.
4726 * Fixed the CMODE command in the client library as well.
4728 * Tested CMODE command in router environment successfully.
4730 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Show the version of the remote client (or server) when connecting
4733 to the server. It is logged to the log file. Affected file
4734 is silcd/protocol.c.
4736 * Fixed the KILLED notify handling in the client library. The
4737 client must be removed from all channels when receiving the
4740 Also, do not remove the client entry when giving the KILL
4741 command but when the KILLED notify is received.
4743 * Removed silc_idlist_find_client_by_nickname from the server.
4744 Not needed anymore. Affected files silcd/idlist.[ch].
4746 * Implemented the CHANNEL_CHANGE notify type handling to the
4747 server. Affected file silcd/server.c.
4751 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Added silc_server_send_notify_invite to send the INVITE
4754 notify between routers.
4756 * Implemented the INVITE command correctly to the server.
4758 * Implemented the INVITE notify type handling in the server.
4760 * Implemented the INVITE command to the client library and on the
4763 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Added function silc_server_get_client_resolve to find the
4766 client entry by ID from all ID lists and then resolve it
4767 (using WHOIS) if it cannot be found. Affected file is
4770 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4772 * Implemented the BAN command to the client library.
4774 * The JOIN command in the server now checks the invite list
4777 * Changed the silc_command_reply_payload_encode_va and the
4778 silc_command_payload_encode_va to support that if argument is
4779 NULL it ignores and checks the next argument. Affected file
4780 lib/silccore/silccommand.c.
4782 * Added silc_server_send_notify_ban to send the BAN notify
4783 type between routers.
4785 * Chaned the silc_notify_payload_encode to support that if
4786 argument is NULL it ignores and checks the next argument.
4787 Affected file lib/silccore/silcnotify.c.
4789 * Tested ban lists in router environment successfully.
4791 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4793 * Implemented BAN command to the server, in silcd/command.[ch].
4795 * Removed the BAN and INVITE_LIST modes from the CMODE command
4798 * Added function silc_string_match to regex match two strings.
4799 Affected files lib/silcutil/silcutil.[ch].
4801 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4803 * Redefined parts of the SilcChannelEntry in the server to support
4804 the new ban and invite lists.
4806 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * Redefined the INVITE command. The same command can be used to
4809 invite individuals to the channel but also to manage the invite
4810 list of the channel (to add to and remove from the invite list).
4811 Updated the protocol specs.
4813 * Added new command SILC_COMMAND_BAN that can be used to manage
4814 the ban list of the channel. Updated the protocol specs.
4816 * Removed the channel modes: the SILC_CMODE_BAN and the
4817 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4818 in the CMODE command. The equivalent features are now available
4819 using INVITE and BAN commands. Updated the protocol specs.
4821 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4822 in the network about change in the current ban list. The notify
4823 type is not used by the client.
4825 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4826 support the invite lists.
4828 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4830 * Added new function silc_string_regexify that converts string
4831 including wildcard characters into regex string that can
4832 be used by the GNU regex library. Added into the file
4833 lib/silcutil/silcutil.[ch].
4835 Added silc_string_regex_combine to combine to regex strings
4836 into one so that they can be used as one regex string by
4837 the GNU regex library. Added into the file
4838 lib/silcutil/silcutil.[ch].
4840 Added silc_string_regex_match to match two strings. It returns
4841 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4843 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4845 * Imported GNU regex to the soruce tree into lib/contrib.
4846 Fixed some compiler warning from the regex.c.
4848 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Fixed MOTD command in the server to work in router environment.
4852 * Fixed the MOTD command in the client library to support
4853 the server argument in the command.
4855 * Added `nickname_len' argument to the silc_idlist_add_client
4856 in the server, as the `nickname' argument may be binary data
4859 * Added silc_idlist_get_channels to return all channels from
4862 * Implemented LIST command to the server. Affected file is
4865 * Implemented the LIST command to the client library and on the
4868 * Added [<user count>] argument to the LIST command reply.
4869 With private channels the user count is not shown.
4871 * Updated TODO and README.
4873 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * The client entry's data.registered must be TRUE even with
4876 global client entry on global client list. The data.registered
4877 is used to check whether the client is anymore in the network,
4878 for example with WHOWAS command so it must be valid.
4880 * Fixed the WHOWAS command in the server. It now actually works
4881 in router environment. Added function into silcd/command_reply.c
4882 silc_server_command_reply_whowas_save.
4884 * Added silc_idlist_purge function to the silcd/idlist.c
4885 to periodically purge the ID Cache.
4887 * Fixed INFO command in the server. It works now in router
4888 environment. Added <server name> argument to the INFO command
4889 reply. Updated the protocol specs.
4891 * Fixed minor bug in silc_idcache_purge to not purge if the
4892 expire value is zero.
4894 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4895 they were buggy because of the WHOWAS information.
4897 * Fixed local command MSG to handle the async resolving of
4898 the remote client properly. It used to fail the first MSG.
4899 Affected file silc/local_command.c.
4901 * Added `data_len' field to SilcIDCache context.
4903 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4905 * Update TODO. Todo in commands in the server.
4907 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4910 used by routers as broadcast packet to inform other routers
4911 about the changed user mode.
4913 Implemented the notify handling in the server. Affected file is
4914 silcd/packet_receive.c. Added the function
4915 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4917 * Added new generic Channel Payload and deprecated the New Channel
4918 Payload. The New Channel Payload is now the generic Channel
4921 * Added new argument `mode' to the silc_server_send_new_channel
4922 as it is required in the Channel Payload now.
4924 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4925 and created a new and real SilChannelPayload to represent the
4926 new generic Channel Payload. Implemented the encode/decode
4927 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4929 * Added silc_server_get_client_channel_list to return the list
4930 of channels the client has joined for WHOIS command reply.
4931 Affected file silcd/server.[ch].
4933 * Implemented the channel list sending in the WHOIS command reply
4934 in server and in the client.
4936 Implemented the channel list displaying on the user interface
4937 as well. Affected file silc/client_ops.c.
4939 * Added silc_channel_payload_parse_list to parse list of Channel
4940 Payloads. It returns SilcDList list of SilcChannelPayloads.
4941 Client for example can use this function to parse the list of
4942 channels it receives in the WHOIS command reply. The caller
4943 must free the list by calling silc_channel_payload_list_free.
4944 Affected files lib/silccore/silcchannel.[ch].
4946 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Added one new argument <user mode> to the WHOIS command reply
4949 to return the mode of the user in SILC. Updated the protocol
4952 Implemented it to the server and client.
4954 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Fixed the mode printing on the user interface on joining.
4957 Affected file silc/client_ops.c.
4959 * Implemented the UMODE command and user modes in general to the
4960 client library and to the user interface.
4962 * Implemented the UMODE command to the server.
4964 * The server now sends UNKNOWN_COMMAND error status if client sends
4965 unknown command. Affected file silcd/command.c.
4967 * All server commands now handle the command identifier the right
4968 way when sending the command reply to the client. The client can
4969 use to identify the command replies with the identifier.
4971 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Added silc_server_get_client_route to resolve the route to
4974 the client indicated by the client ID. Affected file is
4977 * Added silc_server_relay_packet as general function to relay
4978 packet to arbitrary destination. This deprecates functions
4979 like _send_private_message_key, _relay_notify etc. Affected
4980 file is silcd/packet_send.[ch].
4982 Removed silc_server_send_key_agreement,
4983 silc_server_send_private_message_key and
4984 silc_server_packet_relay_notify functions from the file
4985 silcd/packet_send.[ch].
4989 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4990 server. Affected file silcd/packet_receive.[ch].
4992 * Implemented the KILL command to the client. Implemented the
4993 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4994 Affected files lib/silcclient/command[_reply].c and
4995 lib/silcclient/client_notify.c. Implemented the KILL notify
4996 printing in the user inteface.
4998 * Fixed a lot silc_parse_nick memory leaks from the client
4999 library in the file lib/silcclient/command.c.
5001 * Changed the silc_server_send_notify_on_channels's `sender'
5002 argument from SilcSocketConnection to SilcClientEntry to
5003 check the sender as entry and not as connection object and not
5004 to send to the client provided as argument. The affected file
5005 is silcd/packet_send.[ch].
5007 * The notify packets that are destined directly to the client used
5008 to not to be processed by the server. Now changed that and the
5009 server processes all notify packets. After relaying the packet
5010 to the client the notify packet is processed in the server.
5012 * The silc_server_free_client_data now checks whether there is
5013 pending outgoing traffic for the client and purges the data to
5014 the network before removing the client entry.
5016 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5019 an client is killed from the SILC Network. Updated the protocol
5022 Added new function silc_server_send_notify_killed to the
5023 silcd/packet_send.[ch].
5025 * Added function silc_server_packet_relay_notify to relay notify
5026 packets that are destined directly to a client. In this case
5027 the server does not process the notify packets but merely relays
5028 it to the client. Affected file silcd/packet_send.[ch].
5030 Added also silc_server_packet_process_relay_notify to check
5031 whereto relay the notify. Affected file is
5032 silcd/packet_receive.[ch].
5034 * Implemented the KILL command to the server.
5038 * Added the backup schema desgined last fall to the protocol
5039 specs for everyone to see. The specification is in the
5040 *-spec-xx.txt draft and the packet type definitions for the
5041 backup routers is in *-pp-xx.txt draft. Thusly, added also
5042 new packet type SILC_PACKET_CELL_ROUTERS.
5044 * A big security problem in the implementation discovered. The
5045 signoff of an client did not cause new channel key generation
5046 which it of course should've done. The channel keys must be
5047 always re-generated when client leaves (or signoffs) the channel.
5048 The silc_server_remove_from_channels funtion now handles
5049 the channel key re-generation.
5051 * Added `sender' argument to the silc_server_send_notify_on_channels
5052 to not to send the client provided as argument. Affected file
5053 silcd/packet_send.[ch].
5055 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Implemented OPER and SILCOPER commands into the server and
5060 * Added silc_auth_verify and silc_auth_verify_data to verify
5061 the authentication directly from the authentication payload.
5062 It supports verifying both passphrase and public key based
5063 authentication. Affected file lib/silccore/silcauth.[ch].
5065 * Added `hash' field to the SilcIDListData structure. It is the
5066 hash negotiated in the SKE protocol. Affected file is
5069 * Slight redesigning of the SilcAuthPayload handling routines.
5070 Do not send SilcPKCS but SilcPublicKey as argument.
5072 * Implemented the public key authentication support to the
5073 serverconfig. The public key is loaded from the provided path
5074 and saved as authentication data to void * pointer. Thus,
5075 changed the unsigned char *auth_data to void *auth_data;
5077 * Fixed SHUTDOWN command to send the reply before the server
5078 is shutdown. :) Affected file silcd/command.c.
5080 * Fixed fatal bug in CONNECT command. The hostname was invalid
5081 memory and server crashed. Affected file silcd/command.c.
5083 * Fixed fatal bug in CLOSE command. The server_entry became
5084 invalid but was referenced later in the command. Affected file
5087 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5089 * Fixed fatal bug in failure packet handling. Server ignored
5090 the failure and thus crashed when it came.
5094 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5097 that the command may be executed only once in (about) 2 seconds.
5098 The old SILC_CF_LAG flag is same but allows command bursts up
5099 to five before limiting.
5101 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5102 server code. Various commands now includes the CF_LAG_STRICT
5103 flag to disallow any kind of miss-use of the command.
5105 * Fixed the silc_buffer_unformat to not to allocate any data
5106 if the length of the data is zero. It used to allocate the
5107 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5109 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Changed the format of AdminConnection configuration section
5112 in the server. Added username of the admin to the format.
5113 Affected files silcd/serverconfig.[ch].
5115 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5116 to return admin configuration data by host, username and/or
5119 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Implemented WHOWAS command to the server. Added the functions:
5123 silc_server_command_whowas_parse,
5124 silc_server_command_whowas_send_reply,
5125 silc_server_command_whowas_from_client and
5126 silc_server_command_whowas_from_server
5128 * Added <Client ID> argument to the WHOWAS command reply. Updated
5129 the protocol specs accordingly.
5131 * Implemented WHOWAS command and command_reply to the client
5134 Implemented the WHOWAS printing on the user interface.
5136 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * Added new argument to the WHOWAS command reply, the real name.
5139 It is an optional argument. Updated the protocol specs.
5141 * Added SilcIDCacheDestructor callback that is registered when
5142 the SilcIDCache is allocated. The callback is called when
5143 an cache entry in the ID Cache expires, or is purged from the
5144 cache. Added into lib/silccore/idcache.[ch].
5146 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5147 to destruct the client entries when the cache entry expires.
5148 Other ID Cache's in server and in the client library ignores
5151 * If the ID Cache entry's `expire' field is zero then the entry
5152 never expires. Added boolean `expire' argument to the
5153 silc_idcache_add function in the lib/silccore/idcache.[ch].
5154 If it is TRUE the default expiry value is used.
5156 * Added silc_server_free_client_data_timeout that is registered
5157 when client disconnects. By default for 5 minutes we preserve
5158 the client entry for history - for WHOWAS command.
5160 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Added support to the server to enforce that commands are not
5163 executed more than once in 2 seconds. If server receives
5164 commands from client more frequently, timeout is registered
5165 to process the commands. Affected file silcd/command.c.
5166 Added new function silc_server_command_process_timeout.
5168 * Changed NICK_NOTIFY handling in client library to check that
5169 if the client's nickname was changed, so there is no need to
5170 resolve anything from the server.
5172 * Removed error printing from the WHOIS and IDENTIFY commands.
5173 If error occurs then it is ignored silently in the client library.
5174 The application, however, may map the received error to
5175 human readable error string. The application currently maps
5176 the NO_SUCH_NICKNAME error to string.
5178 * Made the command status message public to the application. Moved
5179 them from lib/silcclient/command_reply.c to
5180 lib/silcclient/command_reply.h. The application can map the
5181 received command status to the string with the
5182 silc_client_command_status_message function.
5184 * Added check to the server to check that client's ID is same
5185 as the Source ID in the packet the client sent. They must
5188 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Added dist-bzip hook to the Makefile.am to make bzip2
5191 compressed distributions.
5193 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Server now enforces the maximum length for the nickname and
5196 the channel as protocol specification dictates. 128 bytes for
5197 nickname and 256 bytes for channel name.
5199 * Moved the WHOIS printing to the application. The client libary
5200 does not print out the WHOIS information anymore, the application
5201 must do it. Renamed silc_client_command_reply_whois_print to
5202 the silc_client_command_reply_whois_save.
5204 The client's idle time is also sent to the application now, and
5205 the idle is shown on screen.
5207 * Added silc_client_command_reply_identify_save to save the
5208 received IDENTIFY entries.
5210 * Do not check for channel private keys in message sending and
5211 reception if the channel does not have the PRIVKEY mode set.
5212 Affected file lib/silclient/client_channel.c.
5214 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5217 just surfaced after chaning the JOIN procedure.
5219 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Added silc_client_get_clients_by_list to get client entries
5222 from Client ID list, that is returned for example by JOIN
5223 and USERS command replies. The application should use this
5224 function for example when JOIN command reply is received to
5225 resolve the clients already on the channel (library does not
5226 do that anymore as USERS command reply is not used in the JOIN
5227 procedure anymore). Affected files lib/silcclient/silcapi.h and
5228 lib/silcclient/idlist.c.
5230 * JOIN command reply and USERS command reply returns now SilcBuffer
5231 pointers instead of unsigned char pointers when returning
5232 the client list and mode list.
5234 * Added <Client ID> argument to the JOIN command reply, mainly
5235 for the server to identify for which client the command was
5236 originally sent. Updated protocol specs accordingly.
5238 * Added SilcDlist private_key pointer to the SilcChannelEntry
5239 in the client to support the channel private keys. Affected
5240 file is lib/silcclient/idlist.h.
5242 * Added SilcChannelPrivateKey argument to the function
5243 silc_client_send_channel_message so that application can choose
5244 to use specific private ke if it wants to. If it is not provided,
5245 the normal channel key is used, unless private keys are set.
5246 In this case the first (key that was added first) is used
5247 as the encryption key.
5249 * Implemented the support for channel private key handling.
5250 Implemented the following functions:
5252 silc_client_add_channel_private_key,
5253 silc_client_del_channel_private_keys,
5254 silc_client_del_channel_private_key,
5255 silc_client_list_channel_private_keys and
5256 silc_client_free_channel_private_keys
5258 Affected file lib/silcclient/client_channel.c.
5260 * Added the support for the private keys in the channel message
5261 sending and encryption and in the message reception and
5262 decryption. Affected funtions are
5263 silc_client_send_channel_message and silc_client_channel_message.
5265 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * Added SKE's key verify callback to the client library's
5268 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5270 * Removed the statement that server (or router) must send USERS
5271 command reply when joining to the channel so that the client
5272 knows who are on the channel. Instead, the client list and
5273 client's mode list is now sent in the JOIN command reply to the
5274 client who joined channel. This is better solution.
5276 * Added function silc_server_get_users_on_channel and function
5277 silc_server_save_users_on_channel to the silcd/server.[ch].
5279 * Removed function silc_server_command_send_users from the
5282 * Do not show topic on the client library anymore. The topic is
5283 sent in the command reply notify to the application and the
5284 application must show the topic now.
5286 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Added client searching by nickname hash into the IDENTIFY and
5289 WHOIS commands in the server as they were clearly missing from
5290 them. Affected file is silcd/command.c.
5292 * Fixed a bug in private message receiving in the client library.
5293 The remote ID was freed and it wasn't supposed, now it is
5296 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Minor fix to the channel payload; allocate the data area, as it
5299 needs to be of specific length.
5301 * If the key agreement port is zero then the operating
5302 system will define the bound port. Affected files are
5303 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5305 * Added new function silc_channel_payload_decrypt into the file
5306 lib/silccore/silcchannel.[ch].
5308 * Moved the channel message etc, check from silc_packet_decrypt
5309 to applications. The library calls now a generic
5310 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5311 when the packet is either normal or special. This was done to
5312 allow more wide range of checking that was not allowed when
5313 the code was in library. Now applications can do virtually any
5314 checks to the packet and return to the library the decision how
5315 the packet should be processed. Affected files are
5316 lib/silccore/silcpacket.[ch].
5318 Added silc_server_packet_decrypt_check to the server and
5319 silc_client_packet_decrypt_check to the client library.
5321 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5322 to send with specified source and destination information.
5324 * Channel message delivery between routers was broken after the
5325 channel key distribution was fixed earlier. The channel key
5326 was used be to distributed to other routers as well which is not
5327 allowed by the protocol. Now this is fixed and channel keys
5328 really are cell specific and the channel message delivery between
5329 routers comply with the protocol specification.
5331 * Fixed various commands in server to check also the global list
5332 for the channel entry and not just the local list. The affected
5333 file silcd/command.c.
5335 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Added assert()s to buffer formatting and unformatting routines
5338 to assert (if --enable-debug) when error occurs. Affected
5339 file: lib/silcutil/silcbuffmt.c.
5341 * Changed to auto-reconnect to check whether the remote host is
5342 router and register the re-connect timeout if it is. It used
5343 to check that whether we are normal server, but router must do
5344 auto-reconnect with another router as well. Affected file
5347 * Removed the [<key len>] option from CMODE command as the cipher
5348 name decides the key length, nowadays. See the defined ciphers
5349 from the protocol specification.
5351 * Added [<hmac>] option to the CMODE command to define the HMAC
5352 for the channel. Added SILC_CMODE_HMAC channel mode.
5354 * Added [<hmac>] option for the JOIN command so that user can
5355 select which HMAC is used to compute the MACs of the channel
5358 * Added Hmac field to the Channel Message Payload. The integrity
5359 of plaintext channel messages are now protected by computing
5360 MAC of the message and attaching the MAC to the payload. The
5361 MAC is encrypted. Now, it is clear that this causes some
5362 overhead to the size of the packet but rationale for this is that
5363 now the receiver can verify whether the channel message decrypted
5364 correctly and also when private keys are set for the channel the
5365 receiver can decrypt the packet with several keys and check from
5366 the MAC which key decrypted the message correctly.
5368 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5369 lib/silccrypt/silccipher.[ch].
5371 * Added silc_hash_len to return the digest length into the
5372 lib/silcrypt/silchash.[ch].
5374 * Rewrote parts of Silc Channel Payload interface in the
5375 lib/silccore/silcchannel.[ch]. The encode function now also
5376 encrypts the packet and parse function decrypts it.
5378 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Fixed a minor formatting bug in the SKE's key material processing.
5381 It actually might have processed the keys wrong way resulting
5384 * Redefined the mandatory HMAC algorithms and added new algorithms.
5385 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5386 and hmac-md5 truncated to 96 bits. The mandatory is now
5387 hmac-sha1-96. Rest are optional (including the one that used
5388 to be mandatory). Rationale for this is that the truncated HMAC
5389 length is sufficient from security point of view and can actually
5390 make the attack against the HMAC harder. Also, the truncated
5391 HMAC causes less overhead to the packets. See the RFC2104 for
5394 * Added new [hmac] configuration section. The SKE used to use
5395 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5396 is of course wrong. The official names that must be proposed in
5397 the SKE are the ones defined in the protocol specification
5398 (hmac-sha1-96 for example). The user can configure any hmac
5399 using any hash function configured in the [hash] section. At
5400 least, the mandatory must be configured.
5402 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5404 * Added HMAC list to the SKE proposal list. It has now both
5405 hash algorithm list and HMAC list. This makes the protocol
5406 incompatible with previous versions. The SKE now seems to work
5407 the way it is supposed to work, for the first time actually.
5409 * Defined plain Hash algorithms to the protocol specification.
5412 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5414 * Implemented support for key agreement packets into the server.
5415 Added functions silc_server_key_agreement and
5416 silc_server_send_key_agreement. Other than these functions,
5417 server has nothing to do with this packet.
5419 * Added support for private message key packets into the server.
5420 Added functions silc_server_private_message_key and
5421 silc_server_send_private_message_key.
5425 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5426 called in the protocol's final callback instead in the END
5427 protocol state. This makes a little more sense and in the same
5428 time in client we can use the same protocol routines for normal
5429 key exchange and to key agreement packet handling as well.
5431 * Added to both client's and server's KE protocol context the
5432 SilcSKEKeyMaterial pointer to save the key material. We will
5433 bring the key material to the protocol's final callback by doing
5434 this. The final callback must free the key material.
5436 * Added SKE's packet_send callback into client's KE protocol
5437 context so that the caller can choose what packet sending function
5438 is used. This way we can use different packet sending when
5439 doing normal SKE when doing key agreement packet handling (in
5440 the key agreement packet handling we do not want to encrypt
5443 * Implemented the responder side of the key agreement routines
5444 in the client. The client can now bind to specified port and
5445 accept incoming key negotiation. The key material is passed
5446 to the application after the protocol is over.
5448 * Implemented the processing of incoming Key Agreement packet
5449 in the client. Added function silc_client_key_agreement to
5452 * Implemented the intiator side of the key agreement routines
5453 in the client. The client can now initiate key agreement with
5454 another remote client. The key material is passed to the
5455 application after the protocol is over.
5457 * Created client_keyagr.c to include all the key agreement
5460 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5461 SILC_TASK_CALLBACK except that it is not static.
5463 * Created client_notify.c and moved the Notify packet handling
5464 from the client.[ch] into that file.
5466 * Created client_prvmsg.c and moved all private message and
5467 private message key routines from the client.[ch] into that file.
5469 * Create client_channel.c and moved all channel message and
5470 channel private key routines from the client.[ch] into that file.
5472 * Changed silc_client_get_client_by_id_resolve to resolve with
5473 WHOIS command instead of IDENTIFY command, in the file
5474 lib/silclient/idlist.c.
5476 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Implemented the SKE's responder side to the Client library.
5480 * When FAILURE is received to the protocol do not trust it
5481 blindly. Register a timeout to wait whether the remote closes
5482 the connection as it should do it, only after that process the
5483 actual failure. This was changed to both client and server.
5485 * Added client_internal.h to include some of the structures
5486 there instead of client.h in lib/silcclient/.
5488 * Added function silc_task_unregister_by_callback to unregister
5489 timeouts by the callback function.
5491 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Some "Incomplete WHOIS info" errors has been appearing on the
5494 log files. Took away the entry->userinfo check from WHOIS
5495 reply sending. The entry->userinfo is now " " if client did not
5496 provide one. I thought this was fixed earlier but something
5497 is wrong still. Let's see if the error still appears.
5499 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5501 * Fixed a minor bug in the login when the channel key is
5502 re-generated in the server. It used to generate the key in
5503 wrong order and thus caused problems in the channel traffic.
5505 * Fixed a minor bug in channel key distsribution after
5506 KICK command. The key was not sent to the router even though
5509 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * Added silc_ske_process_key_material_data as generic routine
5512 to process any key material as the SILC protocol dictates. The
5513 function is used by the actual SKE library but can be used by
5514 applications as well. This relates to the private message keys
5515 and the channel private keys since they must be processed the
5516 same way the normal SILC session keys. The protocol dictates
5517 this. Affected files: lib/silcske/silcske.[ch].
5519 Added also silc_ske_free_key_material to free the
5520 SilcSKEKeyMaterial structure.
5522 * Defined silc_cipher_set_key function to set the key for
5523 cipher without using the object's method function. The affected
5524 files: lib/silccrypt/silccipher.[ch].
5526 * Implemented silc silc_client_add_private_message_key,
5527 silc_client_add_private_message_key_ske,
5528 silc_client_del_private_message_key,
5529 silc_client_list_private_message_keys and
5530 silc_client_free_private_message_keys functions in the
5533 Added functions silc_client_send_private_message_key to send
5534 the Private Message Key payload and silc_client_private_message_key
5535 to handle incoming Private Message Key payload.
5537 * Added Cipher field to the Private Message Key payload to set
5538 the cipher to be used. If ignored, the default cipher defined
5539 in the SILC protocol (aes-256-cbc) is used.
5541 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Removed lib/silcclient/ops.h file.
5545 Redefined parts of the SILC Client Library API. Created new
5546 file silcapi.h that deprecates the ops.h file and defines the
5547 published Client Library API. Defined also private message key
5548 API and channel private key API into the file.
5550 This is the file that the application must include from the
5551 SILC Client Library. Other files need not be included by
5552 the application anymore.
5554 * Added new key_agreement client operation callback and also
5555 defined the Key Agreement library API for the application.
5557 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5559 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5560 is used by clients to request key negotiation between another
5561 client in the SILC network. If the negotiation is started it
5562 is performed using the SKE protocol. The result of the
5563 negotiation, the secret key material, can be used for example
5564 as private message key.
5566 Implemented the Key Agreement payload into the files
5567 lib/silccore/silauth.[ch].
5569 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * Redefined ciphers for the SILC protocol. Added some new ciphers
5572 and defined the key lengths for the algorithms. Changed the
5573 code accordingly. The default key length is now 256 bits.
5575 * Fixed SKE key distribution function silc_ske_process_key_material
5576 when the key length is more than 128 bits. The default key
5577 length in SILC is now 256 bits.
5579 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5580 to indicate unsupported algorithm.
5582 * Renamed rijndael.c to aes.c and all functions as well.
5584 * Fixed a long standing channel key setting bug in client library.
5585 Weird that it has never surfaced before.
5587 * Fixed bug in channel deletion. If the entire channel is removed
5588 then it must also delete the references of the channel entry
5589 from the client's channel list as the client's channel entry and
5590 the channel's client entry share same memory.
5592 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Implemented CONNECT and SHUTDOWN commands in the client.
5596 * Implemented CLOSE command to the client.
5598 * Added the function silc_idlist_find_server_by_name into the
5599 files silcd/idlist.[ch].
5601 Added the function silc_idlist_find_server_by_conn into the
5602 files silcd/idlist.[ch].
5604 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * DIE command was renamed to SHUTDOWN. Updated the both code
5609 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5610 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5612 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5615 * Added function silc_server_create_connection function to create
5616 connection to remote router. My server implementation actually
5617 does not allow router to connect to normal server (it expects
5618 that normal server always initiates the connection to the router)
5619 so the CONNECT command is only good for connecting to another
5622 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5625 or some other client was kicked from the channel.
5627 Implemented the handling of the notify type to both client
5630 Implemented silc_server_send_notify_kicked to send the KICKED
5631 notify. It is used to send it to the server's primary router.
5633 * Implemented the KICK command into server and client.
5635 * Added `query' argument to the silc_idlist_get_client function
5636 to indicate whether to query the client from server or not if
5639 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5640 to indicate that the client is not channel founder.
5644 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Removed the rng context from SilcPacketContext structure and
5647 changed that the packet routine uses the Global RNG API.
5649 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Added support for quit message that client can "leave" on the
5652 channel when it quits the SILC. It is ditributed inside the
5653 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5655 Added silc_server_free_client_data that will take the
5656 signoff message as argument.
5658 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5660 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Updated parts of the protocol specification to keep it up
5665 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5668 payloads in one packet.
5670 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5671 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5672 use now the new List flag.
5674 * Also deprecated the following packet types: REPLACE_ID,
5675 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5677 * Added list support for Notify packet in server.
5679 * Added silc_server_send_notify_channel_change to send the
5680 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5681 the silc_server_send_replace_id.
5683 * Added silc_server_send_notify_nick_change to send the
5684 NICK_CHANGE notify type. Deprecates the function
5685 silc_server_send_replace_id.
5687 * Added silc_server_send_notify_join to send the JOIN notify type.
5688 Deprecates the function silc_server_send_new_channel_user.
5690 * Added silc_server_send_notify_leave to send LEAVE notify type.
5691 Deprecates the function silc_server_send_remove_channel_user.
5693 * Added silc_server_send_notify_cmode and
5694 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5695 types. Deprecates the silc_server_send_set_mode function.
5697 * Added SERVER_SIGNOFF notify type to indicate that server has
5698 quit. This means that all clients on the channel from that
5699 server will drop. This can be also used when netsplit happens.
5701 Deprecated REMOVE_ID packet type since it is not needed anymore
5704 Added silc_server_send_notify_server_signoff to send the
5705 SERVER_SIGNOFF notify type. Deprecates the function
5706 silc_server_send_remove_id.
5708 Added also silc_server_send_notify_signoff to send the
5709 SIGNOFF notify type.
5711 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5712 SILC protocol from this day on. Changed the protocol
5713 specification as well.
5715 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5716 notify type. It is used between routers to notify about
5717 topic changes on a channel.
5719 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5722 * Partly updated the protocol specification to comply with the
5723 changes now made. It is still though a bit outdated.
5725 * The JOIN notify type now takes one extra argument <Channel ID>.
5726 The packet used to be destined to the channel but now the
5727 JOIN type may be sent as list thus it is impossible to
5728 destine it to any specific channel. By adding this argument
5729 it is again possible.
5731 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Added CREDITS file. The CHANGES and CREDITS file will appear
5734 in the distribution as well.
5736 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5739 types in the server's silcd/packet_receive.c.
5741 * Implemented CMODE and CUMODE to work in router environment.
5743 * Fixed minor encoding and decoding buglet from the
5744 lib/silccore/silcmode.c.
5746 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5749 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5751 * Changed all SilcConfigServer* and silc_config_server* to
5752 SilcServerConfig* and silc_server_config*, respectively.
5755 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Associated the ID (client or server ID) to the Authentication
5758 Payload to avoid any possibility of forging. Updated the
5759 protocol specification and the code accordingly.
5761 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * The RSA key length is now save to the RsaKey context in the
5764 key generation process in lib/silccrypt/rsa.c. The key length
5765 is now used to figure out the maximum size of the block allowed
5766 to be encrypted/signed.
5768 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5769 is equivalent to the silc_mp_mp2bin but does not allocate any
5772 * Changed silc_mp_mp2bin API to take length argument. If it is
5773 non-zero then the buffer is allocated that large. If zero, then
5774 the size is approximated using silc_mp_sizeinbase, which however
5777 * Created Global RNG API which is global RNG that application can
5778 initialize. After initializing, any routine anywhere in the
5779 code (including library) can use RNG without allocating a new
5780 RNG object. This was done to allow this sort of use of the
5781 RNG in code that has no chance to allocate RNG object. All
5782 applications currently allocate this and many routines in the
5783 library use this. Affected file lib/silccrypt/silcrng.[ch].
5785 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5786 it to use the Global RNG API.
5788 * Defined Authentication Payload into protocol specification that
5789 is used during SILC session to authenticate entities. It is
5790 used for example by client to authenticate itself to the server
5791 to obtain server operator privileges.
5793 Implemented this payload into the lib/silccore/silcauth.[ch].
5794 Implemented also routines for public key based authentication
5795 as the new protocol specification dictates.
5797 Moved definitions of different authentication methods from
5798 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5800 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5801 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5802 silc_pkcs_verify_with_hash functions into the file
5803 lib/silccrypt/silcpkcs.[ch].
5805 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * The client entry's userinfo pointer must be always valid.
5808 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5809 will fail since it requires the userinfo. Now, the userinfo
5810 is allocated as "" if actual userinfo does not exist. Actually,
5811 it must exist and it is totally Ok to drop client connections
5812 that does not announce the userinfo. However, we will make
5813 this workaround for now.
5815 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5816 to return the remote port by socket.
5818 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5821 SILC_SERVER_PENDING_EXEC and added an new macro
5822 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5823 data or when error occurs while processing the pending command.
5825 Added new argument `destructor' into silc_server_command_pending
5826 and to the SilcServerCommandPending object. This destructor is
5827 now called after calling the pending callback or if error occurs
5828 immediately. If error occurs the actual pending callback won't
5829 be called at all - only the destructor. The destructor may be
5830 NULL if destructor is not needed.
5832 All this applies for client library code as well. Similar
5833 changes were made there as well for the pending commands.
5835 In the client, the application must now allocate the
5836 SilcClientCommandContext with the silc_client_command_alloc
5839 * Added reference counter to the SilcServerCommandContext. Added
5840 function silc_server_command_alloc and silc_server_command_dup
5843 Same type of functions added to the client library for the same
5846 * Removed the cmd_ident from IDListData away since it is now
5847 global for all connections. It is the command identifier used
5848 in command sending and with pending commands. The affected file
5851 * Added reference counter to the SilcSocketConnection objecet to
5852 indicate the usage count of the object. The object won't be
5853 freed untill the reference counter hits zero. Currently only
5854 server uses this, and client ignores it. The client must be
5855 set to use this too later. The affected files are
5856 lib/silccore/silcsockconn.[ch]. Added also the function
5857 silc_socket_dup to increase the reference counter.
5859 This was mainly added because it is possible that the socket
5860 is removed underneath of pending command or other async
5861 operation. Now it won't be free'd and proper DISCONNECTING
5862 flags, etc. can be set to avoid sending data to connection that
5863 is not valid anymore.
5865 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5866 the connection. After that it sets SILC_SET_DISCONNECTED.
5867 It is, however, possible that the socket data is not still freed.
5868 The silc_server_packet_process now checks that data is not
5869 read or written to connection that is DISCONNECTED. The socket
5870 get's freed when the reference counter hits zero.
5872 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5874 * Changed the client operation API: channel_message operation's
5875 `sender' is now the client entry of the sender, not the nickname
5876 and the `channel' is the channel entry, not the channel name.
5878 In the private_message operation the `sender' is now also the
5879 client entry of the sender not the nickname.
5881 Affected file is lib/silcclient/ops.h and all applications
5882 using the client operations.
5884 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Moved the calling of ops->connect() from connect_to_server_final
5887 into receive_new_id functin since that is the point when the
5888 client is actually allowed to send traffic to network. The
5889 affected file is lib/silcclient/client.c.
5891 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5893 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5894 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5895 (if needs broadcasting) instead of broadcasting the packets one
5896 by one which would make a burst in the network traffic.
5898 * Added `broadcast' argument to the functions in silcd/server.[ch]
5899 silc_server_create_new_channel[_with_id] to indicate whether
5900 to send New Channel packet to primary router.
5902 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * Added new function into the silcd/server.[ch] files:
5905 silc_server_create_new_channel_with_id to create new channel with
5906 already existing Channel ID.
5908 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5909 lib/silccore/silcpacket.h. This packet is used t send list of
5910 Set Mode payloads inside one packet. Server uses this to set
5911 the modes for the channels and clients on those channels, that it
5912 announced to the router when it connected to it. The protocol
5913 specification has been updated accordingly.
5915 * The silc_server_new_channel did not handle the packet coming
5916 from normal server as it normally does not send that. However,
5917 when it announces its channels it does send it. Implemented
5918 the support for that.
5920 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5921 into the file lib/silccore/id.h.
5923 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Fixed memory leaks in the functions silc_idlist_del_client,
5926 silc_idlist_del_channel and silc_idlist_del_server in the file
5927 silcd/idlist.c. All of those leaked like a sieve.
5929 * Fixed some small memory leaks in the client's function
5930 silc_client_notify_by_server.
5932 * Added functions into silcd/server.c: silc_server_announce_clients,
5933 silc_server_announce_channels and silc_server_announce_server.
5934 These functions are used by normal and router server to announce
5935 to its primary router about clients, channels and servers (when
5936 router) that we own. This is done after we've connected to the
5939 These functions effectively implements the following packet types:
5940 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5941 and SILC_PACKET_NEW_ID_LIST.
5943 * Added new functions into the silcd/packet_receive.[ch]:
5944 silc_server_new_id_list, silc_server_new_channel_list and
5945 silc_server_new_channel_user_list to handle the incoming
5946 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5948 * Added support of changing Channel ID in the function
5949 silc_server_replace_id. If the server that announces a channel
5950 to the router already exists in the router (with same name but
5951 with different Channel ID), router is responsible to send
5952 Replace ID packet to the server and force the server to change
5953 the Channel ID to the one router has.
5955 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5956 client that the Channel ID has been changed by the router. The
5957 normal server sends this to the client. Client must start using
5958 the new Channel ID as the channel's ID.
5960 Implemented handling of this new type into lib/silcclient/client.c
5961 into the function silc_client_notify_by_server.
5963 * Added new function silc_idlist_replace_channel_id into the files
5964 silcd/idlist.[ch] to replace the Channel ID.
5966 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Call silc_server_command_identify_check always when processing
5969 the IDENTIFY command in silcd/command.c
5971 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5974 send keepalive packets. The packet can be sent by clients,
5975 servers and routers.
5977 Added function silc_socket_set_heartbeat into the file
5978 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5979 If not set, the heartbeat is not performed. The actual
5980 heartbeat is implemented in the low level socket connection
5981 library. However, application is responsible of actually
5984 Added silc_server_send_heartbeat to send the actual heartbeat
5985 packet into silcd/packet_send.[ch]. Server now performs
5986 keepalive with all connections.
5988 * Added silc_task_get_first function into lib/silcutil/silctask.c
5989 to return the timeout task with shortest timeout. There was a bug
5990 in task unregistration that caused problems. TODO has been
5991 updated to include that task system must be rewritten.
5993 * The client library will now resolve the client information when
5994 receiving JOIN notify from server for client that we know but
5995 have incomplete information.
5997 * Rewrote parts of silc_server_remove_from_channels and
5998 silc_server_remove_from_one_channel as they did not remove the
5999 channel in some circumstances even though they should've.
6001 * Encryption problem encountered in server:
6003 The LEAVE command used to send the Channel Key packet to the
6004 router immediately after generating it. However, the code
6005 had earlier sent Remove Channel user packet but not immediately,
6006 ie. it was put to queue. The order of packets in the router
6007 was that Channel Key packet was first and Remove Channel User
6008 packet was second, even though they were encrypted in the
6009 reverse order. For this reason, MAC check failed. Now, this
6010 is fixed by not sending the Channel Key packet immediately but
6011 putting it to queue. However, this is more fundamental problem:
6012 packets that are in queue should actually not be encrypted
6013 because packets that are sent immediately gets encrypted
6014 actually with wrong IV (and thus MAC check fails). So, packets
6015 that are in queue should be encrypted when they are sent to
6016 the wire and not when they put to the queue.
6018 However, the problem is that the current system has not been
6019 designed to work that way. Instead, the packet is encrypted
6020 as soon as possible and left to the queue. The queue is then
6021 just purged into wire. There won't be any fixes for this
6022 any time soon. So, the current semantic for packet sending
6025 o If you send packet to remote host and do not force the send
6026 (the packet will be in queue) then all subsequent packets to the
6027 same remote host must also be put to the queue. Only after the
6028 queue has been purged is it safe again to force the packet
6031 o If you send all packets immediately then it safe to send
6032 any of subsequent packets through the queue, however, after
6033 the first packet is put to queue then any subsequent packets
6034 must also be put to the queue.
6036 Follow these rules and everything works fine.
6038 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6040 * Added new function silc_server_remove_clients_by_server to
6041 remove all client entries from ID list when the server connection
6042 is lost. In this case it is also important to invalidate all
6043 client entires as they hold the invalid server entry. This
6044 fixes fatal bug when server has lost connection and will reconnect
6047 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6049 * Made some sanity checks to silc_server_daemonise like to check
6050 whether the requested user and group actually exists.
6052 * Added sanity check to SKE's silc_ske_responder_finish to check
6053 that the public and private key actually is valid.
6055 * Invalidate the client's nickname when receiving Replace ID
6056 packet and the Client ID is being replaced. This means that the
6057 server will query the nickname if someone needs it (client)
6060 * Sort the ID Cache in client library when the ID Cache data
6061 has changed (needs sorting).
6063 * Do not allow for SILC client to create several connections to
6064 several servers. The client does not support windows right now
6065 and generating multiple connections causes weird behaviour.
6067 Irssi-silc client does support windows and can handle several
6068 connections without problems, see: www.irssi.org and SILC plugin.
6070 * Fixed some places where client was added to the IDList. The
6071 rule of thumb is following (in order to get everything right):
6072 If the client is directly connected local client then the
6073 `connection' argument must be set and `router' argument must be
6074 NULL to silc_idlist_add_client function. If the client is not
6075 directly connected client then the `router' argument must
6076 bet set and the `connection' argument must be NULL to the
6077 silc_idlist_add_client function.
6079 * The funtion silc_server_packet_send_local_channel actually did
6080 not check whether the client was locally connected or not. It
6081 does that now. Fixed a bug related to LEAVE command.
6083 * Fixed Remove Channel User payload parsing bug in server's
6084 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6086 * The server's silc_server_save_channel_key now checks also the
6087 global ID list for the channel as it might not be in the local
6088 list. Fixed a bug related to LEAVE command.
6090 * Is this the end of the [<unknown>] buglet that has been lurking
6091 around for a long time? A little for loop fix in server's
6092 silc_server_command_whois_parse that is used by both IDENTIFY
6093 and WHOIS command. At least, this was a clear bug and a cause
6094 of one type of [<unknown>] buglet.
6096 * WHOIS and IDENTIFY commands call the function
6097 silc_server_command_[whois/identify]_check function even if
6098 we are not router server.
6100 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6102 * Added --with-gmp configuration option. If set the GMP
6103 is always compiled in the SILC source tree. If not set then
6104 it is checked whether the system has the GMP3 installed. If
6105 it has then the GMP won't be compiled (the system's headers
6106 and library is used), if it doesn't have it then the GMP is
6107 compiled in the SILC source tree.
6109 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6111 * Changed RSA private exponent generation to what PKCS #1
6112 suggests. We try to find the smallest possible d by doing
6113 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6114 not security fix but optimization.
6116 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Added new config entry [Identity] to fork the server and run
6119 it as specific user and group. A patch from Bostik.
6121 * Imported Dotconf configuration library into lib/dotconf.
6122 This will be used to create the SILC configuration files later.
6123 It will appear in the distsribution after this commit.
6125 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * A big code auditing weekend happening. Auditing code for
6128 obvious mistakes, bugs and errors. Also, removing any code
6131 Removed files for being obsolete:
6133 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6134 inline in the file lib/silcutil/silcbuffer.h)
6136 o lib/silcutil/silcbufutil.c (the header has inline versions)
6138 Changed code to fix possible error conditions:
6140 o The buffer formatting routines now check that the destination
6141 buffer really has enough space to add the data. This applies for
6142 both buffer formatting and unformatting
6143 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6144 unformatting was changed to accomodate following rules:
6145 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6146 sent to the function while XXX_*STRING will not allocate or copy
6147 the data into the buffer. Instead it sets the pointer from the
6148 buffer into the pointer sent as argument (XXX_*STRING used to
6149 require that the pointer must be allocated already). This change
6150 makes this whole thing a bit more consistent and more optimized
6151 (note that the data returned in the unformatting with XXX_*STRING
6152 must not be freed now). The routines return now -1 on error.
6154 o Tried to find all code that use buffer_format and buffer_unformat
6155 and added return value checking to prevent formatting and
6156 especially unformatting errors and possible subsequent fatal
6159 o Changed ske->x and ske->KEY to mallocated pointers in
6160 lib/silcske/silcske.h. Fixed possible data and memory leak.
6162 o Added return value checking to all *_parse* functions. Fixed
6163 many memory leaks as well.
6165 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6166 so that buffer overflows would not happen. All code now also
6167 checks the return value as it can fail.
6169 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Added reconnection support to server if the normal server looses
6172 its connection to the router (for example if router is rebooted).
6173 The server performs normal reconnection strategy implemented
6174 to the server. Affected file silcd/server.c.
6176 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Added new packet type SILC_PACKET_SET_MODE that is used to
6179 distribute the information about changed modes (for clients,
6180 channels and clients channel modes) to all routers in the
6181 network. Updated the protocol specification accordingly.
6183 Added functions into silcd/packet_send.c and
6184 silcd/packet_receive.c: silc_server_send_set_mode,
6185 silc_server_set_mode.
6187 Added new files silcmode.[ch] into lib/silccore that implements
6188 the encoding and decoding of Set Mode Payload. Added new type
6189 SilcSetModePayload. Moved the definitions of different modes
6190 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6192 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6194 * Oops, a little mistake in server's connection authentication
6195 protocol. The protocol is not ended with FAILURE but with
6196 SUCCESS if the authentication is Ok. :) Affected file is
6199 * Implemented NICK_CHANGE notify handling in server in the file
6200 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6201 the local clients on the channel. After the changing nickname
6202 in router environment snhould work and the [<unknown>] nickname
6203 should appear no more.
6205 The silc_server_replace_id function that receives the Replace ID
6206 payload now sends the NICK_CHANGE notify type also in the file
6207 silcd/packet_receive.c
6209 * Changed WHOIS and IDENTIFY command to support the maximum amount
6210 of arguments defined in protocol specs (3328 arguments). This
6211 fixed a bug that caused problems when there were more than three
6214 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6216 * Added extra parameter, command identifier, to the
6217 silc_client_send_command so that explicit command identifier
6220 Changed that ID list routines uses specific command identifier
6221 when sending WHOIS/IDENTIFY requests to the server so that they
6222 can be identified when the reply comes back.
6224 Affected files lib/silcclient/command.[ch],
6225 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6227 * Added `sender' argument to silc_server_packet_send_to_channel
6228 to indicaet the sender who originally sent the packet to us
6229 that we are now re-sending. Ignored if NULL. Affected file
6230 silcd/packet_send.[ch].
6232 * Added some server statistics support in silcd/server_internal.h
6233 SilcServerStatistics structure and around the server code. Also
6234 send some nice statistics information when client is connecting
6237 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * Fixed channel ID decoding in server's JOIN command reply in
6240 silcd/command_reply.c
6242 * Fixed braodcasting of replace ID payload to not to send it if
6243 we are standalone server in silcd/packet_receive.c.
6245 * Fixed all channel message sending routines to not to send
6246 packets to clients that has router set, since they are routed
6247 separately in the same function earlier. Affects file
6248 silcd/packet_send.c and all channel packet sending functions.
6250 * In USERS reply, res_argv[i] are not allocated, the table
6251 is allocated. Thus changed that free the table, not its
6254 * In server's whois_check and identify_check if the client is
6255 locally connected do not send any WHOIS commands - they are not
6258 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Fixed some minor bugs in client when sending WHOIS command. The
6261 arguments was in wrong order.
6263 * Removed statis function add_to_channel from server in
6264 silcd/command.c that was previously used with the joining but
6267 * Tested USERS command in router environment successfully with two
6268 routers, two servers and two clients.
6270 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * Reorganized the USERS command and command reply in client library
6273 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6274 When the command is given by user we register a pending command
6275 callback that will reprocess the command after the reply has been
6276 received from the server. When reprocessing the packet we then
6277 display the information. Thus, the USERS information is displayed
6278 now in the command callback instead of in the command reply
6279 callback. The processing of the command is same as previously
6280 when server has sent the command reply in the JOINing process.
6282 * Added to USERS command in silcd/command_reply.c to join the client,
6283 we didn't use to know about, to the channel after we've created
6284 a client entry for it. Also, for clienet we did know already still
6285 check whether it is on the channel or not and add it if not.
6287 * Removed silc_server_command_join_notify as the function and its
6290 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6292 * Changed the client's pending command handling to the same as the
6293 server's pending command handling. It is also now possible to
6294 execute command reply functions from other command reply
6295 function as the function callbacks for commands and command
6296 replies are one and same. The pending commands are not static
6297 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6298 in client connection context. Thus, pending commands are server
6299 connection specific as it is convenient.
6301 Changed the function silc_client_command_pending and
6302 silc_client_command_pending_del and added new function
6303 silc_client_command_pending_check. Removed the
6304 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6307 * Added cmd_ident, current command identifier, to the client
6308 connection context in lib/silcclient/client.h to keep track on
6309 command identifiers used in command sending. Client's command reply
6310 function handling now supports the mandatory command identifiers.
6312 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6313 funtions in client to fully support pending command callbacks.
6315 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6316 as one of the arguments to the application in the command reply
6319 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6320 before first releasing SILC but came back. Now it is removed again
6321 and should come back nomore. The FORWARDED flag was used only
6322 by the JOINing procedure by forwarding the command packet to router.
6323 Now, the JOINing procedure has been changed to more generic (due
6324 to various router environment issues) and FORWARDED is not needed
6325 anymore for anything. The protocol specification is yet to be
6328 Now, removed silc_server_packet_forward from server and the flag
6329 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6331 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * Renamed NAMES command to USERS command. The NAMES was named that
6334 due to historical reasons. Now it is renamed. Also, rewrote
6335 parts of the USERS command. The nickname list is not sent anymore
6336 by the server. Only Client ID and mode lists are sent in the USERS
6337 command. Changed this also to the protocol specification.
6339 The client now resolves the names and stuff after it receives
6340 the USERS list from the server when joining to the channel.
6342 * WHOIS and IDENTIFY commands has been changed to support multiple
6343 Client ID's per command. One can now search for multiple users
6344 in the network by sending only one WHOIS or IDENTIFY command.
6345 Changed the code and the protocol specifications.
6347 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6348 uses silc_server_command_whois_parse to parse the request. */
6350 * If normal server, do not parse the WHOIS and IDENTIFY requests
6351 before sending it to the router. Saves some time.
6353 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * Fixed JOIN command on client library. Wrong number of arguments
6356 used to crash the client.
6358 * Added silc_server_channel_has_global function to check whether
6359 channel has global users or not.
6361 * Added silc_server_channel_has_local function to check whether channel
6362 has locally connected clients on the channel.
6364 * The silc_server_remove_from_one_channel now checks whether the
6365 channel has global users or not after given client was removed from
6366 the channel. It also checks whether the channel has local clients
6367 on the channel anymore. If it does not have then the channel entry
6368 is removed as it is not needed anymore.
6370 * The silc_server_notify now checks on JOIN notify whether the joining
6371 client is one of locally connected or global. If it is global then
6372 the channel has now global users on the channel and that is marked
6373 to the channel entry. Also, it now saves the global client to
6374 global list who is joining and JOINs it to the channel. This is
6375 for normal server, that is.
6377 Changed silc_server_send_notify_on_channel,
6378 silc_server_packet_relay_to_channel and
6379 silc_server_packet_send_to_channel check if we are normal server
6380 and client has router set (ie. global client) do not send the
6381 message to that client, as it is already routed to our router.
6383 * Implemented LEAVE notify type handling in silc_server_notify
6386 * Tested LEAVE command in router environment successfully. Tested
6387 with two routers, two servers and two clients.
6391 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6393 * Implemented SIGNOFF notify type handling in silc_server_notify
6396 * silc_server_remove_id now removes the client entry from all channels
6397 it has joined and thusly sends SIGNOFF notify type.
6399 * Rewrote the NAMES list generation in server by removing two excess
6400 loops. The lists are created now inside one loop.
6402 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * silc_server_remove_channel_user checks now also global list
6405 for channel and client.
6407 * silc_server_new_channel_user checks now both local and global
6408 list for channel and client. Fixed a bug in client id decoding.
6409 Used to decode wrong buffer.
6411 * silc_server_channel_message checks now both local and global
6412 list for channel entry.
6414 * Tested channel joining (hence JOIN) in router environment
6415 successfully. Tested with two routers, two servers and two
6418 * Tested channel message sending in router environment successfully.
6420 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6422 * Added silc_server_save_channel_key into server.[ch] to save the
6423 received channel key in Channel Key payload processing. It is
6424 also used in JOIN command reply handling.
6426 Equivalent function silc_client_save_channel_key added into
6427 client.[ch] into client library.
6429 * Changed JOIN command reply to send information whether the channel
6430 was created or not (is existing already) and the channel key
6431 payload. Changed protocol specs accordingly.
6433 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6434 the request was sent by ID and not by nickname. Crashed on
6437 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6439 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6440 now correctly save the received data.
6442 * silc_server_free_sock_user_data now notifies routers in the
6443 network about entities leaving the network.
6445 At the same time implemented functions silc_server_remove_id
6446 and silc_server_send_remove_id to receive and send REMOVE_ID
6447 packets. The packet is used to notify routers in the network
6448 about leaving entities. The ID removed will become invalid in
6451 * Added function silc_idlist_del_server into server. Removes and
6452 free's server entry from ID list.
6454 * silc_server_private_message function now checks, if we are router,
6455 that the destination ID really is valid ID, naturally.
6457 * In router when NEW_ID packet is received (for new client) the
6458 hash of the Client ID is saved in the ID Cache but the
6459 client->nickname is set to NULL, instead of putting the hash
6462 IDENTIFY command now also checks that client->nickname must be
6463 valid. If it is not if will request the data from the server who
6464 owns the client. Added new function
6465 silc_server_command_identify_check.
6467 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6468 to set the command to already allocated Command Payload.
6470 * Tested private message sending in router environment with two
6471 routers, two servers and two clients. Fixed minor bugs and now
6474 * Fixed segfault from client's NAMES command. Used to crash if
6477 * Forwarded packets must not be routed even if it is not destined
6478 to the receiver. Changed server code comply with this.
6480 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6482 * Added `require_reverse_mapping' boolean value to ServerParams
6483 structure. If TRUE (not default) the server will require that
6484 the connecting host has fully qualified domain name.
6486 If the reverse mapping is not required and hostname could not be
6487 found the IP address is used as hostname.
6489 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6491 * Implemented version string checking to both client and server.
6492 The check is incomplete currently due to the abnormal version
6493 strings used in development version of SILC.
6495 * Changed all command functions in server to use the new
6498 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6500 * Changed char *data to unsigned char *data in ID Cache system to
6501 support binary data as ID Cache data. Changed code to support
6502 binary data in lib/silccore/idcache.c.
6504 * Renamed silc_server_packet_relay_command_reply to
6505 silc_server_command_reply as it is normal packet receiving
6506 function. Rewrote the function to accept command replys for
6507 servers and not only for clients.
6509 * Mark remote router always as registered server if we are connecting
6510 to it. Otherwise, commands sent by the router to us are ignored.
6512 * All ID List find routines now returns the ID Cache Entry pointer
6513 as well if requested.
6515 * WHOIS command works now in router environment, tested with two
6516 routers, two servers and two clients.
6518 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6519 in router environment (as it is almost equivalent to WHOIS) but
6520 hasn't been tested thoroughly. Added new functions:
6522 silc_server_command_identify_parse
6523 silc_server_command_identify_send_reply
6524 silc_server_command_identify_from_client
6525 silc_server_command_identify_from_server
6527 * Disabled route cache adding because adding two different ID's with
6528 same IP replaces the old cache entry thus giving wrong route.
6529 The entry->router->connection is always the fastest route anyway
6530 so route cache may not be needed. Of course, new routes maybe
6531 established after receiving the ID when the entry->router->connection
6532 might not be anymore the most optimal.
6534 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Add route cache for received ID for fast routing.
6538 * Added silc_server_packet_route to route received packet on router
6539 that is not destined to us.
6541 * Renamed silc_server_get_route to silc_server_route_get.
6543 * Added id_string and id_string_len fields into SilcServer to
6544 include encoded ServerID for fast comparing without excess
6545 encoding of the ID's.
6547 * Cleaned up WHOIS command on server side. Added following static
6550 silc_server_command_whois_parse
6551 silc_server_command_whois_check
6552 silc_server_command_whois_send_reply
6553 silc_server_command_whois_from_client
6554 silc_server_command_whois_from_server
6556 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6557 arguments in command replies. All command functions should be
6558 updated to use this macro.
6560 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6562 * Minor typo fixes on command reply handling on server.
6564 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6566 * Added silc_server_command_add_to_channel internal routine to add
6567 the client to the channel after router has created the channel and
6568 sent command reply to the server.
6570 * Added generic silc_server_send_command to send any command from
6573 * Use static buffer with ID rendering instead of duplicating data.
6575 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6577 * Fixed a channel user mode bug when joining to a channel server gave
6578 everybody channel founder rights, oops.
6580 * We mark ourselves as the router of the incoming server connection
6581 if we are router ourselves. This way we can check in some packet
6582 sending functions whether it is locally connected server. For
6583 incoming router connections we put NULL.
6585 * For router sending packets locally means now always sending the
6586 packet cell wide; to local clients and local servers. For normal
6587 server sending packet locally means sending it to only local
6590 * Fixed the JOIN command to really work in router environment. If the
6591 channel is created it is always created by the router. Router is
6592 also responsible of making the initial joining to the channel,
6593 sending JOIN notify to the sending server and distributing
6594 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6595 does not exist server doesn't do anything else but forward the
6596 command to the router which performs everything.
6598 * Added silc_server_send_channel_key function to send the Channel Key
6601 * Added silc_server_create_channel_key to create new channel key. The
6602 channel key is now re-generated everytime someone joins or leaves
6603 a channel, as protocol dictates. Note: channel->key_len is the
6606 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6608 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6609 packet_receive.[ch] to separate packet sending and receiving
6610 routines. The server.[ch] now includes everything else including
6611 actual packet processing (writing and reading data) and other
6614 Renamed silc_server_private_message_send_internal to
6615 silc_server_send_private_message. The routine is still though
6616 used only to relay private messages as server does not send
6617 private messages itself.
6619 Renamed silc_server_new_channel to silc_server_create_new_channel
6620 and added new function sicl_server_new_channel that handles the
6621 incoming New Channel packet. Added also new sending function
6622 silc_server_send_new_channel to send New Channel Payload.
6624 * Added new function silc_server_notify to process incoming notify
6625 packet to the server/router. Server may then relay the notify
6626 to clients if needed.
6628 * Added new function silc_server_new_channel_user to process incoming
6629 New Channel User packet. Router will redistribute the packet and
6630 send JOIN notify to its local clients and locally connected servers
6631 if needed. Normal server will send JOIN notify to its local client
6632 on same channel when received this packet. Added also corresponding
6633 sending function silc_server_send_new_channel_user to sent the
6636 * Added boolean route argument to send_notif_to_channel and
6637 packet_send_to_channel functions to attempt to route the packet
6638 if it is TRUE and send only locally if it is FALSE.
6640 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6642 * silc_server_replace_id now broadcasts the received replace ID
6643 packet if it is not broadcast packet already. The router must
6644 broadcast to inform other routers about changed ID.
6646 * Added backpointer to server's router into SilcServer context in
6647 silcd/server_internal.h.
6649 * Fixed silc_server_packet_broadcast to send correct broadcast
6652 * The channel key is now distributed to the local client as soon
6653 as it is received from the router (in router environment) so that
6654 no other packet may be sent for the channel until client has
6657 * silc_server_remove_channel_user now broadcasts the received
6658 Remove Channel User packet if it is not broadcast packet already.
6659 The router must broadcast to inform other routers about removed
6662 * Added users field into SilcPacketContext that is a reference count
6663 of the context. One can increase the reference count by calling
6664 silc_packet_context_dup which is now changed to just increase the
6665 reference count instead of duplicating the data. The reference
6666 count is decresed by calling silc_packet_context_free that will
6667 free the data after the reference count hits zero.
6669 For now on the packet context and everything allocated into it
6670 (including the raw packet from network) must be freed by calling
6671 the new silc_packet_context_free function. Added also new function
6672 silc_packet_context_alloc that must be used now to allocate the
6673 context. This also means that if a routine is asynchronous from
6674 silc_[client/server]_packet_parse_type the packet context must
6675 be duplicated by calling silc_packet_context_dup. Otherwise it
6676 gets free'd after silc_[client/server]_packet_parse_type returns.
6677 Also, one must remember that if packet is duplicated then its
6678 reference count must be decresed by calling the free function as
6679 many times as it was duplicated.
6681 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6682 from both client and server.
6684 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Made joining to a channel working in router environment.
6688 * Cleaned up JOIN command on server side and create function
6689 silc_server_command_join_channel internal routine to make the
6692 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * Changed silc_command_pending list to SilcDList. Also, added
6695 `ident' field to SilcServerCommandPending structure to identify
6696 the reply and to call correct callback.
6698 Added silc_server_command_pending_check function to replace the
6699 corresnponding macro. The silc_command_pending list is not
6702 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6703 to set identifier to previously allocated Command Payload. It
6704 is used to set identifier for command when resending Command
6707 * Added silc_command_payload_encode_payload to encode Command
6708 Payload buffer from SilcCommandPayload structure.
6710 * Added silc_argument_payload_encode_payload to encode Argument
6711 payload buffer from SilcArgumentPayload structure.
6713 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6715 * Changed WHOIS command to support router connection on server side.
6716 The whois request is always sent to router unless the server is
6717 standalone server. After server has received the reply from the
6718 router will it send the reply to the client.
6720 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6721 broadcast received broadcast packet. The function is used only
6722 by router. The broadcast packet is always sent to the router's
6725 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6726 render given ID to printable string, for log files for example.
6728 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6730 * Made basic router to router connections working. At least they
6731 can now connect to each other but nothing really works the way
6732 they are supposed - yet.
6734 * Added new initiator token to RouterConnection configuration
6735 file in silcd/serverconfig.[ch]. It is used to tell whether we
6736 are the initiator to the remote router or whether we'll expect
6737 the other end to connect.
6739 * Moved registering of listener task to silc_server_init, hence
6740 the server starts listenning as soon as it is run, even if it
6741 does not have connections to other routers. Let's see how well
6744 * Changed default connection retry timeouts for more suitable in
6747 * Removed cipher and such arguments from silc_idlist_add_client
6748 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6749 Added new function silc_idlist_add_data to add the keys and stuff
6752 * Added SilcIDListData structure and added it to SilcClientEntry
6753 and SilcServerEntry as their first field in the structure. This
6754 way we can explicitly cast the ID entries to the SilcIDListData
6755 structure and get common data for the entries. In past, we had
6756 to first check what type of connection it is and then cast it to
6757 correct ID entry type. Now, we can directly cast the opaque
6758 pointer to the SilcIDListData (no matter what ID entry it actually
6759 is) and get the data needed.
6761 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6763 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6764 in some circumstances even if threre were timeout tasks, though not
6765 IO tasks, but tasks anyway. Now fixed.
6767 * Defined SilcServerConnection structure to hold connection specific
6768 stuff about directly connected servers and routers. The definition
6769 is currently in silcd/server_internal.h. I thought about having
6770 a bit more important role fro this struct but for now it is used
6771 only when connecting to other server (or router actually).
6773 * Added connecting retry support in server when connecting to
6774 router(s). The retry feature implement exponential backoff
6775 algorithm. Also, added SilcServerParams structure to hold default
6776 parameters for server. For now, it include these retry settings
6777 and are hard coded. After server is moded to be as Silc Server
6778 Library this structure will be more important.
6780 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * Changed client librarys channel->clients table to SilcList and
6783 changed code accordingly.
6785 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6787 * Changed client's channel table to SilcList and changed code
6788 accordingly. Also changed SilcChannelClientEntry to include back-
6789 pointer to the channel so that client entry can use that structure
6790 as list as well and we have fast cross-reference to the channel.
6791 This change dramatically decreased the complexity of channel
6792 handling with client entry and vice versa (removed one extra
6793 loop when searching for channel entry from many functions).
6795 * Changed server->sim from table to SilcDList and changed code
6798 * NAMES command can now be used from user interface. It will show
6799 the user list on the channel, neatly.
6801 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6802 Code now saves realname of the user if it becomes available.
6804 * Renamed configure.in to configure.in.pre and made ./prepare
6805 script to automatically add correct version string to
6806 configure.in which it creates from configure.in.pre.
6808 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6810 * NAMES command reply now shows users mode with the nickname when
6813 * Moved silc_client_ch[u]mode[_char] functions from
6814 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6815 place sucks, they are utility functions and should be in some
6818 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6820 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6823 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6827 * Added TRQ (efficient deque and list library) into lib/trq. This is
6828 a very good list library that is currently used in the SILC. Defined
6829 SilcList API over the library because I didn't like the API very
6830 much. See lib/trq/silclist.h for the API and examples of how to
6831 use the API. Fixed various places in the code to use the new
6832 SilcList API. The SilcList is meant for lists that has a structure
6833 already defined as a list. It is not suitable to add just some
6834 context to the list (in TRQ, the context is the list actually).
6836 So, I defined SilcDList that can be used for the purpose where
6837 predefined list structure does not exit. This can be used as
6838 such list. Now some context just can be added to the SilcDList.
6839 Currently this list is not used in the SILC just yet, though there
6840 are a lot places where this can replace dynamically allocated
6841 tables and I will fix these places, later, to use SilcDList.
6842 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6843 and use TRQ internally).
6845 Also fixed some annoying warning messages that the original TRQ
6846 code generated. Also minor changes to TRQ's Makefile.in.
6848 * Added support for querying by Client ID to both WHOIS and
6849 IDENTIFY commands into server, as required by the protocol.
6851 * Removed method function pointers from SilcBuffer structure. They
6852 weren't used to anything and just increased the context size for
6853 no good reason. This change also made silc_buffer_alloc and
6854 silc_buffer_free functions inline functions.
6856 * Disabled command flooding detection support until it's fixed so
6857 that it accepts commands in but does not execute them more than once
6860 * Added silc_net_localhost(), to return local hostname, into
6861 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6862 that must be initialized before calling silc_client_init.
6864 * Added new function: silc_server_send_notify_on_channels to send
6865 notify messages to all channels client has joined. It is assured
6866 that the message is sent only once per client.
6868 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6869 lib/silcutil/silcutil.[ch] as silc_format function. The new
6870 function is generic and is used by server as well, not only by
6871 the logging routines.
6873 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6874 the provided version string was not acceptable. Added new function:
6875 silc_ske_check_version into lib/silcske/silcske.h. The function
6876 must be implemented by the application (client or server) and it
6877 does not reside in the SKE library. The function checks the version
6878 string remote end sent.
6880 * Added back pointers (to opaque context and to SilcSocketConnection)
6881 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6883 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6884 duplicate packet context structure.
6886 * Changed `notify' client operation to send same arguments as client
6887 receives from server except for ID's. ID's are mapped to correct
6888 ID entry and that is returned. Also, if channel entry is not sent
6889 by server but the notify is for channel the channel entry is sent
6890 to application (otherwise application doesn't know that it is for
6891 channel (library gets it from packet's Destination ID)).
6893 * Added silc_client_remove_from_channels into client library to
6894 remove a client from all channels it has joined to. Used when
6895 received SIGNOFF notify from server. Added also new function
6896 silc_client_replace_from_channels to replace old ID entry with
6897 new ID entry on all channels. Used when received NICK_CHANGE
6900 * Fixed ID Cache list handling in silc_idlist_get_client in
6901 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6902 to get (or query) client by ID.
6904 * Updated TODO list.
6906 * Added connection authentication status message defined by the
6907 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6908 support for these into the code in client and server side.
6910 * Added generic function silc_client_send_command to send any command
6911 with variable argument list. Application should use this function
6912 to send commands if the command functions provided by the library
6913 does not suite for the application's user interface needs.
6915 * Added new `failure' client operation. Application is notified about
6916 received failure packet if client is executing a protocol. In this
6917 case the protocol's execution has failed.
6919 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6920 is required by the protocol.
6922 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6923 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6926 * Added status flag to SilcSKE object to indicate realtime status
6927 of the SKE protocol.
6929 * Application receives now exactly same command reply arguments as
6930 the library receives from server. However, if ID is received the
6931 corresponding ID entry is returned to the application (eg. Client
6932 ID is mapped to correct SilcClientEntry entry and that is returned).
6933 Changed command_reply client operation due to this change.
6935 * Changed all ID's in commands and in command replys as ID Payloads.
6936 Change affected both client and server side codes.
6938 All ID's sent in SILC network (with execption of ID's in SILC
6939 Packet header) are sent in ID Payload to support variable length
6942 * Server now notifies nick changes and notifies all clients on
6943 the channels about the new nickname (about the new Client ID,
6946 * Implemented CMODE command to change channel modes. Supports all
6947 channel modes defined by the protocol specs except ban and invite
6948 lists. (Also, private channel key mode is supported but support for
6949 setting private channel key in client is missing, thus, this mode
6950 has no effect on client side (except that server requires that the
6951 client uses private channel key and normal channel traffic does not
6954 Also, invite mode works per se, but INVITE command does not work
6955 yet correctly, so you can set channel as invite only channel but
6956 inviting clients to the channel does not work (it is yet to be
6957 thought what's the best way to do it).
6959 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6960 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6961 Implemented CUMODE command to change user's mode on the channel.
6962 Supports all modes defined by the protocol specs.
6964 * Added NAMES command reply to return users modes on the channel.
6966 * Removed unnecessary and slow ciphers from lib/silccrypt.
6968 * Set SO_KEEPALIVE option to connection sockets by default.
6970 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6972 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6973 redefined the Notify Payload into protocol specs.
6975 * Added silc_id_payload_parse_id to get ID directly from raw
6978 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6980 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6981 accept searching by Client ID as well.
6983 * Added support for LEAVE and SIGNOFF notify types in client library.
6985 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6986 to parse ID Payload from raw data.
6988 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6990 * Added flags parameter into silc_ske_assemble_security_properties
6991 function in lib/silcske/silcske.[ch].
6993 * Changed notify client operation to fit better for notify messages
6994 sent by server. The notify payload received from server is now
6995 passed to the application (after parsing it to SilcNotifyPayload).
6996 It is application's responsibility to retrieve the arguments
6997 from the payload and show the message the way it wants. The message
6998 sent by server is implementation specific.
7000 * Changed public keys to comply with the protocol specification.
7001 Old public keys are not supported anymore and are not compatible.
7003 * Removed nickname from Channel Payload as the latest draft removed
7004 it. The client must resolve the nickname from the NAMES command
7005 reply received when it joined the channel.
7007 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7009 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7011 * Fixed some errors in protocol specification drafts.
7013 * Created lib/silccore/silcnotify.c to implement Notify Payload
7014 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7015 generic payloads described by protocol specifications. The file
7016 includes implementations for ID Payload and Argument Payload.
7018 * Changed Command Payload implementation to use the new Argument
7019 Payload. Changed command_xxxx_payload to command_payload_xxxx
7020 to comply with SILC coding conventions.
7022 * Added suppport for Argument Payload handling in Notify Payload
7023 implementation as protocol requires it. Added the new support
7024 into server and client lib as well.
7026 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7028 * Added support for multiple nicknames on same channel. [n] is
7029 added locally to the nickname if there are more than one same
7030 nicknames on the channel.
7032 * Server now sends all nicknames that matched WHOIS request.
7033 Client also shows the list received from server.
7035 * Added TOPIC command to client side. User can now set and show
7036 current topic on channel.
7038 * Added MOTD command to client and server. Also, server sends the
7039 motd when client connects to the server.
7041 * Changed version strings to comply ISO 8601.
7043 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7045 * Fixed protocol error handling in client library. It should now
7046 cope even if the SKE fails for some reason.
7048 * Made new protocol specification drafts for submitting to IETF.
7050 * Implemented TOPIC command to server in silcd/command.c.
7052 * Added two new notify types into lib/silccore/silcnotify.h:
7053 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7054 notify nickname change and topic setting/change on a channel.
7056 * API change of command_reply operation in client library. The
7057 application gets now the status type received from server as well.
7059 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7061 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7063 * Cras fixed and optimized the packet handling even further and
7064 it should work now. Minor change to the prototype of function
7065 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7067 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7069 * Added new function into lib/silcutil/silcschedule.[ch]:
7070 silc_schedule_with_fd to select() a specified fd. The function
7071 returns after timeout expires or data arrives or goes. The
7072 function is used by packet routines to wait that all data is
7073 received from network.
7075 * Fixed data reading from network in lib/silccore/silcpacket.c.
7076 The code now assures that all data is read from the fd and then
7077 continues packet processing. This was a bug fix since the code
7078 used to drop some data in some circumstances.
7080 * Added new function into lib/silcclient/client.[ch]:
7081 silc_client_start_key_exchange to start key exchange after
7082 connection has been established to server. The code internally
7083 now uses this funtion but its main purpose was to provide it
7084 for applications that perform their own connecting. After
7085 application has created a connection it merely calls this
7086 function to start the key exchange between client and server.
7087 The library takes care of everything else after that.
7089 Updated also lib/silcclient/README to explain the usage of
7092 * Do not send to application information that connection has
7093 been established. Application gets notified it by connect
7096 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * Applied cras's patch to add silc_schedule_one function. The
7099 function runs scheduler once and returns.
7101 * Fixed the scheduler after cras messed it up. The timeout
7102 handling works now as it's supposed to work.
7104 * Added into lib/silccore/ silcnotify.h to include notify
7105 message types support. Changed silc_server_send_notify*
7106 functions, in server.[ch], to support those new notify types.
7107 Added the support for the notify types into client library,
7108 as well. Added new notify client operation into ops.h in
7111 * Changed silc_server_packet_send_to_channel to send normal
7112 packets instead of just channel message packets. The function
7113 is now used to send the notify packets to channels. It is not
7114 used to send channel message packets anymore, as server never
7117 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7118 va_arg()s as it seems to require it nowadays. I guess, if SILC
7119 is compiled with older va_arg() the new code should work anyway.
7121 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7123 * Splitted core library. Core library (lib/silccore) includes
7124 now only SILC protocol specific core (and common) components.
7125 Created new utility library (lib/silcutil) that includes more
7126 generic purpose stuff. The stuff for util library was taken
7127 from the old core library. This was minor and easy split.
7129 * Created SILC Client Library (lib/silcclient) that includes
7130 implementation of the SILC client without user interface. This
7131 was major move from silc/ directory. The code has been changed
7132 so that it is transparent towards the user interface. The
7133 silc/ directory includes now the same user interface as before
7134 and it uses the new client library. Read lib/silcclient/README.
7135 Basicly, the client library performs everything else related
7136 to SILC except user interface handling. Also, configuration
7137 files are considered to be part of user interface and library
7138 does not handle them.
7140 This change also changed a lot of structures, function naming etc.
7141 Most important change was that SilcClientWindow object was
7142 renamed to SilcClientConnection in the client library. Created
7143 also new file lib/silcclient/ops.h. Also added new files
7144 silc/local_command.[ch] and silc/client_ops.[ch].
7146 All these changes were made to make it easier for user interface
7147 designers to create what ever user interface for the SILC client
7150 It is also expected that the server will be moved to lib
7151 directory as well and SILC Server Library will be created;
7152 sometimes in the future.
7154 * Removed Local commands from lib/silccore/silccommand.h as
7155 they are application specific and new client library does not
7156 handle any of those anymore.
7158 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7159 old client implementation in silc/.
7161 * Added support for callback functions in SILC_LOG_* macros.
7162 Application can now set its own callbacks that will be called
7163 instead of using the default functions that will always print
7164 the debug messages to stderr (or stdout). Also, debugging can
7165 now be disabled by setting silc_debug to FALSE and re-enabled by
7166 setting it to TRUE. Note, that logging will still work even
7167 if debugging is disabled.
7169 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7170 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7171 silc_log_reset_debug_callbacks.
7173 * To enable debugging in silc client one must give now -d
7174 option on command line.
7176 * Changed silc_schedule_init to automatically allocate task queues
7177 if they are not allocated before calling it.
7179 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7181 * Added GMP 3.1 into math library.
7183 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7185 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7186 a channel in SILC network. The packet is used by servers and
7187 routers to notify other routers that user has left a channel.
7188 This little feature was missing until now. Added the feature
7189 to protocol specification as well.
7191 Added functions: silc_server_send_remove_channel_user and
7192 silc_server_remove_channel_user into server.[ch].
7194 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7195 lib/silccore/silcpacket.h. However, they are not implemented
7198 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7200 * Fixed joining to a channel and sending channel messages
7201 between server and router. The channel message sending should
7202 now work inside a cell.
7204 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7206 * Fixed the private message sending between server and router.
7207 The private message sending should now work inside a cell.
7209 * Added silc_server_replace_id into server.[ch] to replace
7210 existing ID in the SILC network.
7212 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7213 and silc_idlist_replace_server_id into idlist.[ch] in server.
7215 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7217 * Fixed the server to server connections. Server can again now
7218 connect to router. Router to router connections probably does
7221 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Added dynamic protocol registering support. Now protocols can
7224 registered and unregistered on the fly. Patch by cras.
7226 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Added lib/contrib directory to hold routines that some platforms
7229 don't have but are needed by SILC.
7231 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7232 into lin/contrib to provide getopt() and getopt_long() for
7233 those who don't have it.
7235 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7237 * Added AWAY command to client. When away message is set and
7238 client receives a private message packet the client automatically
7239 replies to the sender with the away message.
7241 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7242 bug seemed to be the cause of recent problems when compiling
7245 * Added version detection support to SKE protocol specification
7246 and added the new changes to the SKE implementation as well.
7247 There were other minor changes in the SKE protocol as well.
7249 Many changes in lib/silcske/silcske.[ch] and in
7250 lib/silcske/payload.[ch].
7252 * Added ^U functionality, clear input line. Patch from cras.
7254 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7256 * Mainly small bugfixes on core library. Fixed some debugging
7257 logging and buffer overflow in silclog.c.
7259 * Updated config.sub and config.guess on the distribution tree.
7261 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7263 * Added command lagging support in server. Client may execute
7264 commands now only once in two seconds.
7266 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7268 * Optimized packet reception. MAC computation and checking is now
7269 also more optimized. A lot previously duplicated code is now
7270 used as generic by both client and server.
7272 * Fixed key pair generation in clientutil.c
7274 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7276 * Added into lib/silccore/silcbufutil.[ch] new function;
7277 silc_buffer_realloc.
7279 * Moved generic packet sending/encryption functions to
7280 lib/silccore/silcpacket.[ch] from client and server. Some
7281 rewriting of the functions.
7283 * Moved all generic packet reception/decryption functions to
7284 lib/silccore/silcpacket.[ch] from client and server. The
7285 packet processing is now much cleaner in both client and server.
7286 These were major changes in both client and server.
7288 * Created many common functions in server to do packet sending.
7289 Previously code were duplicated a lot, this has been removed
7292 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7294 * Rewrote major parts of the ID cache system. Don't know
7295 whether it is better now or not but at least the API is more
7298 * Major rewrite on ID cache stuff on client because of the ID
7299 cache API changes. Added idlist.c to client.
7301 * Also major rewrite on ID cache stuff on server as well.
7302 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7303 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7304 in hand, instead they are all put into the ID cache system now.
7305 All server_idlist_* routines uses ID cache now instead of
7306 traversing its own lists (those lists does not exist anymore).
7307 SilcIDList though still exists. Also, SilcXXXEntry's are
7310 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7312 * Finally made the SKE implementation compliant to the protocol
7313 specification. All mp integers are now binary encoded as
7314 opposed being HEX encoded.
7316 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7319 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7320 functions: silc_[encode/decode]_pem. Also added function
7321 silc_encode_pem_file to PEM encode with newlines ('\n') for
7324 * SILC public keys are now encoded either PEM or binary. Same
7325 option is for private keys as well. By default private keys
7326 are binary encoded and public keys PEM encoded. Silly HEX
7327 encoding were removed.
7329 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7330 function to create fingerprints.
7332 * Fixed a bug in SHA1; does not change the original data anymore.
7334 * Partly implemented INFO command on client and server side.
7335 Fixed CLEAR command. Changes to SERVER command; show current
7336 server(s) when giving command without arguments. Added
7337 VERSION command to client.
7339 * Added check to server that unregistered connections cannot
7340 execute commands (unless it is specificly allowed).
7342 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7344 * Fixed screen refresh.
7346 * Fixed channel joining bug from client. On some circumstances
7347 client tried to join to a channel it had already joined.
7349 * Added public key verification process into client's protocol.c.
7350 The client now verifies the public key from user and saves
7351 it into ~./silc/serverkeys/ directory.
7353 Added into: clientutil.[ch]: silc_client_verify_server_key.
7355 * Changed SKE protocol's silc_ske_initiator_finish function
7356 to accept callback function that verifies the received public
7357 key. Removed old silc_ske_verify_public_key function.
7359 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7361 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7362 silc_pkcs_private_key[_data]_set.
7364 * Made the password and public authentication more cleaner in
7365 server's protocol.c.
7367 * Removed historic and obsolete protocol `channel_auth' from
7368 both client and server.
7370 * Removed wrong way of sending command status messages from
7371 server to client in server's command.c. The old way violated
7372 protocol specification.
7374 Changes to silccore/silccommand.[ch]: removed
7375 silc_command_encode_status_payload -> not needed anymore,
7376 changed silc_command_encode_payload_va to accept extra
7377 argument on variable argument list. The argument type must
7378 now be provided to the function. Also, added new function:
7379 silc_command_encode_reply_payload_va which is same as
7380 normal command_encode_payload_va except command status type
7381 is provided as extra argument.
7383 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7385 * Added ~./silc directory handling. The directory includes the
7386 public and private keys for the client.
7388 Added silc_client_check_silc_dir, silc_client_create_identifier
7389 and silc_client_load_keys.
7391 * Implemented SILC protocol compliant public key. Added public
7392 and private key saving to and loading from files.
7394 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7395 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7396 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7397 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7398 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7400 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7401 silc_pkcs_load_[public/private]_key.
7403 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7405 * Added silc_server_get_route (route.[ch]) to get connection
7406 data for the fastest route for given ID.
7408 * Implemented INVITE command on client and server. The command
7409 were re-defined in the SILC Protocol Specification and the
7410 implementation now complies with the specification.
7412 * Implemented PING command on client and server.
7414 * Implemented NAMES command on client and server. The server side
7415 supports currently only normal server not router server yet.
7416 Some changes to NAMES definition in SILC protocol specification.
7418 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7420 * Implemented LEAVE command on client and server.
7422 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7423 again. This change was made to the protocol as well. Server
7424 should not violate the protocol specification anymore.
7426 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7428 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7429 was tested. SOCKS4 was not but should work anyway.
