1 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added preliminary support for signals in scheduler. The
4 signals we care about are now blocked always when the scheduler
5 is locked. This way we can synchronise the use of signal with
6 scheduler. It is guaranteed that when signal occurs the scheduler
7 is not locked, and thus new tasks can be safely added to the
10 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
11 to silc_schedule_internal_init and silc_schedule_internal_uninit.
12 Added new platform specific routines
13 silc_schedule_internal_signals_[un]block and
14 silc_schedule_internal_signal_[un]register.
16 Added new functions to SILC Schedule API:
17 silc_schedule_signal_[un]register. Each signal that application
18 is going to use should be registered to the scheduler.
20 Affected files are lib/silcutil/silcschedule.[ch],
21 lib/silcutil/*/silc*schedule.c.
23 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
25 * Check for unauthenticated client and server in the
26 silc_server_new_client and silc_server_new_server functions.
27 Affected file silcd/packet_receive.c.
29 * Added function silc_string_is_ascii to check whether given
30 string is 7-bit ASCII string. Affected files are
31 lib/silcutil/silcutil.[ch].
33 * Added function silc_id_is_valid_server_id into the
34 silcd/serverid.c and added checking for valid Server ID's in
35 silc_server_new_server. The Server ID must always be based
36 on the server's public IP address.
38 * Added logging of DISCONNECT packet message in the server.
39 Affected file silcd/server.c.
41 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
43 * Changed all library interfaces that use Global RNG to also
44 accept SilcRng as argument. Affected files are
45 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
46 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
47 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
48 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
51 * Added function silc_pkcs_generate_key to the
52 lib/silccrypt/silcpkcs.[ch] for applications so that they
53 don't need to do pkcs->pkcs->init calls anymore.
55 * Remove SilcSocketConnection from the SFTP API since it really
56 wasn't needed there. The application has the information
57 saved in its contexts anyway and the SFTP layer doesn't need
58 know about it. Affected files lib/silcsft/silcsftp.h and
59 lib/silcsftp/sftp_[server/client].c.
61 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
62 The SilcSimContext is not SilcSim.
64 * Fixed possible buffer overflows in silc_id_render in the
65 lib/silcutil/silcutil.c.
67 * On EPOC the global crypto module lists are not used at all
68 in the crypto library. Added support for using the constant
69 algorithm list on EPOC. Affected files are
70 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
73 * Fixed the handling of third parameter of KICKED notify, since
74 it was mistakenly updated to SILC Protocol 1.0 even though it
75 is to be included in 1.1. Since it is not in 1.0 it is not
76 mandatory, and this fix now handles it only if it is provided,
77 and it is not error if it is not provided. Affected file
78 lib/silcclient/client_notify.c.
80 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
82 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
83 client. Affected file irssi/src/silc/core/client_ops.c.

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

137 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
139 * If silc_debug is TRUE, also output standard logging messages
140 to stderr with the debug output.
142 Made silc_log_reset_all() flushing all channels before returning.
143 Also fixed some documentation typos.
145 Affected files are lib/silcutil/silclog.[ch].
147 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
149 * Fixed the server to check correctly the amount of connections
150 from single host, by checking also the type of the connection.
151 Fixed also the comparison of number of connections and number
152 of allowed connections. Affected files are silcd/server.c,
155 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
157 * Fixed the USERS command reply to save the user's mode on the
158 channel as well. Fixed JOIN command reply to check whether a
159 client is on channel already and not join it twice. Affected
160 file lib/silcclient/command_reply.c.
162 * Added new file silc-expandos.c into irssi/silc/core/ to return
163 various stuff for various signal for the statusbar etc. updating.
164 Now Irssi SILC client prints channel user modes etc. on the
167 * The user mode (like server/router operator changes) is now shown
168 on the Irssi SILC client's statusbar. The affected files are
169 irssi/src/silc/core/client_ops.c, silc-expandos.c.
171 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>

179 * Fixed -S option parsing in Irssi SILC Client. Affected file
180 irssi/src/silc/core/silc-core.c.
182 * Added silc_buffer_alloc_size function. Affected file is
183 lib/silcutil/silcbuffer.h.
185 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
187 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
188 constants. Affected files in
189 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and

203 * Removed 0.6.x backwards support.
205 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
207 * Changed all integer type names:
208 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
209 to avoid collisions with other libraries using same type names
212 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
214 * Added `prefer_ipv6' argument to the functions
215 silc_net_gethostbyname[_async]. If it is TRUE it will return
216 IPv6 address over IPv4. If FALSE IPv4 address is returned
217 even if IPv6 address was found. Affected files
218 lib/silcutil/silcnet.[ch].
220 * Added support silc_net_create_connection[_async] to fallback
221 to IPv4 address if IPv6 address could not be used (like if

234 application does not need to define them. Affected file
235 includes/silcincludes.h.
237 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
238 old name went against naming convention. Applications now
239 include "silcclient.h" instead of "clientlibincludes.h".
240 Removed includes/clientlibincludes.h, it is redundant now.
242 * Renamed includes/version.h to silcversion.h.
244 * Added really preliminary support for OS/2 into the util
245 library. Only thread & mutex API is implemented, others
246 are still to be implemented. Created the lib/silcutil/os2/
247 directory. Created also file includes/silcos2.h.
249 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
251 * Added preliminary BeOS support into the util library.
252 Created lib/silcutil/beos/, and implemented all the needed

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

292 KICKED notify printing in Irssi SILC Client. Affected file
293 irssi/src/silc/core/client_ops.c.
295 * Fixed a NICK change bug in client library, to not recreate the
296 client_entry->channels hash table everytime nick is changed.
297 Affected file lib/silcclient/client.c.
299 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
301 * ROBOdoc documented the lib/silcske/silcske.h, and improved
302 the SKE interface a bit.
304 * Fixed padding problem in PKCS#1. The padding was not actually
305 random since the random number generator was used incorrectly.
306 This security bug affects only when encrypting with PKCS#1, and
307 it is not currently used at all in SILC. SILC only use signing
308 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
310 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
312 * Rewrote the notify handling in Irssi SILC client to not call

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

353 doc/example_silcd.conf.in.
355 * Removed type casts from silc_calloc(), conforming to the
356 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
358 * Removed param_name member from client, server, and router
359 section structs, now identifying the param directly.
361 Added CONFIG_FREE_AUTH macro in config file parsing.
363 Affected files are silcd/serverconfig.[ch].
365 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>

368 is now done in silc_core_init() which also fixes autoconnecting
371 Affected files irssi/src/silc/core/silc-core.c,
372 irssi/src/fe-text/silc.c.
374 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
376 * Added new configuration options and blocks:
377 keepalive_secs, reconnect_count, reconnect_interval,
378 reconnect_interval_max, reconnect_keep_trying and
379 require_reverser_lookup. Added ConnectionParam block, and
380 implemented the connection parameters when connecting as
381 initiator and when accepting connections as responder.
383 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
384 whether given configuration value has been given already.
386 Affected files silcd/serverconfig.[c], server.[c].
388 * Splitted the doc/example_silcd.conf.in. Separated the crypto
389 algorithm parts and created new file silcalgs.conf, that
390 is now included from the example_silcd.conf.in.
392 * Optimized the silc_server_connect_to_router_second to take
393 the connection configuration object from the SilcServerConnection
394 object instead of finding it during the connecting phase.
395 Added the configuration object to SilcServerConnection struct.
396 Affected files silcd/server_internal.h, server.c.
398 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
400 * Add the client on channel after it was resolved at the
401 channel message receiving, and it was not already on the
402 channel. Affected file lib/silcclient/client_channel.c.
404 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
406 * Fixed the public key authentication to allocate always the
407 destination signature buffer instead of using static buffer.
408 Affected file silcd/protocol.c.
410 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
412 * Unified the serverconfig.[ch]'s helper function interface.
413 Affected file silcd/serverconfig.[ch].
415 * Removed doc/example_silc.conf.in since it is redundant.
416 The make install will now install irssi/silc.conf file.
418 * Added new Passphrase and Publickey authentication methods to
419 config file, allowing both public key and passphrase based
420 authentication to be set at the same time.
422 Added `prefer_passphrase_auth' setting in config file which
423 can be used to set to prefer passwd auth if both passwd and
424 public key is set. If not set, public key is preferred.
425 This has effect only when being initiator (responder will try
428 Added support for authentication with passphrase and public key
429 at the same time. The passphrase is tried first always since
430 it is faster to check.
432 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
434 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

478 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
480 * Fixed the file transfer's key agreement payload to include
481 zero port also if the hostname is NULL because it could not
484 Call file transfer monitor callback now also if error occurs
485 during key agreement protocol.
487 Changed the silc_client_file_send interface to return the
488 SilcClientFileError instead of session id. The session ID
489 is returned into pointer provided as argument.
491 Check that the file exists locally before sending the
492 file transfer request at all.
494 Affected file lib/silcclient/client_ftp.c, silcapi.h.
496 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
497 error than can occur while key agreement protocol. Affected

502 irssi/src/silc/core/silc-channels.c.
504 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
505 SILC_LOG_WARNING to give out Warning and not Error. Affected
506 file lib/silcutil/silclog.c.
508 * Fixed the channel message payload decryption in the function
509 silc_channel_message_payload_decrypt to not modify the original
510 buffer before it is verified that the message decrypted
511 correctly. Otherwise, next time it is called with correct
512 channel key it won't encrypt since the payload is corrupted.
513 Affected file lib/silccore/silcchannel.c.
515 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

527 * Fixed a bug in hash table internal routine for traversing
528 the table with foreach callback. The current entry may
529 become invalid in the callback but it was referenced after
530 the callback returned.
532 Do not allow auto rehashing of hash table during the
533 silc_hash_table_foreach operation, for same reasons as it is
534 not allowed for SilcHashTableList. Affected files are
535 lib/silcutil/silchashtable.[ch].
537 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

545 * Fixed private message handling. It used some old code that
546 caused the client to crash. Affecte file is
547 lib/silcclient/client_prvmsg.c.
549 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
551 * Added function silc_client_add_channel,
552 silc_client_replace_channel_id, and removed functions
553 silc_client_new_channel_id and silc_idlist_get_channel_by_id
556 * Added cross reference of the joined channels to the
557 SilcClientEntry, and changed the SilcChannelEntry's
558 users list to SilcHashTable. The affected files are
559 lib/silcclient/idlist.[ch].
561 * Fixed a bug in hash table tarversing. While the hash table
562 is traversed with SilcHashTableList the table must not be
563 rehashed. It is now guaranteed that auto rehashable tables
564 are not rehashed while tarversing the list. Also defined that
565 silc_hash_table_rehash must not be called while tarversing
566 the table. Added function silc_hash_table_list_reset that must
567 be called after the tarversing is over. The affected files are
568 lib/silcutil/silchashtable.[ch].
570 * Changed all hash table traversing to call the new
571 silc_hash_table_list_reset in server and in client library.
573 * Added function silc_client_on_channel to return the
574 SilcChannelUser entry if the specified client entry is joined
575 on the specified channel. This is exported to application as
576 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
578 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
580 * Fixed founder regaining problem with JOIN command on normal
581 server. The notify for mode change must be sent always and
582 not only if !cmd->pending. Affected file silcd/command.c.
584 * Fixed the WHOWAS command's reply sending to support the
585 lists correctly. Affected file silcd/command.c.
587 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
589 * When sending JOIN command to router for processing the
590 sender's old command identifier was not saved back to the
591 sender's command context, fixed now. The affected file is
594 * Create the key in JOIN command of the router did not return
595 the channel key, added check for this. Affected file is
598 * Fixed a channel ID update bug in JOIN command reply. Do
599 not directly upgrade the ID but call the function
600 silc_idlist_replace_channel_id if the ID was changed.
601 Affected file silcd/command_reply.c.
603 * Fixed memory leaks from command calling if it would fail.
604 Affected file silcd/command.c.
606 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
608 * Applied patches from cras:
610 Memory leak fixes around libaries, irssi window resize fix,
611 new silclist.h and silcdlist.h, all extern inline changed to
614 * Removed dotconf from lib/dotconf, not needed anymore.
616 * Removed TRQ from lib/trq, not needed anymore.
618 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
619 with server connections. Later this will be configurable
620 in config file after new config file is done. Affected file
623 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
625 * Fixed a crash in server related to channel announcements.
626 Affected file silcd/server.c.
628 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
630 * Fixed memory leaks in silc_server_create_new_channel*
631 functions. Affected file silcd/server.c.
633 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
634 which ID was changed. This way the router will send the
635 user list for the channel again, and server won't be in
636 desync in some rare circumstances. Affected file is
637 silcd/packet_receive.c.
639 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
641 * Check for NULL socket pointer in the function
642 silc_server_packet_send_to_channel_real. Affected file
645 * Fixed the BAN notify handling to correctly remove ban
646 list. Affected file silcd/packet_receive.c.
648 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
650 * Fixed some header addition to Toolkit distribution in
651 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
653 * Added lib/silcclient/client_ops_example.h as an template
654 file for application programmers to quickly start using
655 the SilcClientOperation functions in their application.
656 Updated the lib/silcclient/README as well to tell about this
657 nice file made available.
659 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
661 * Call silc_server_remove_from_channels when removing client
662 entry when NO_SUCH_CLIENT_ID was received. Affected file
663 is silcd/command_reply.c.
665 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
667 * Added server & router operator statistics updating. Affected
668 file silcd/packet_receive.c and silcd/command.c.
670 * Fixed the SERVER_SIGNOFF notify handling on normal server
671 not to save the history information for clients. Same was
672 fixed earlier in remove_clients_by_server function, but not
673 here. Affected file silcd/packet_receive.c.
675 * Raised the default connection-retry count from 4 to 7 in
676 server. Affected file silcd/server.h.
678 * Cancel any possible reconnect timeouts when we start the
679 key exchange. Affected file silcd/server.c.
681 * Do not reconnect on connection failure when SCONNECT was
682 given. Affected files silcd/server.[ch].
684 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
686 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
688 * Fixed the NICK command to always give the unformatted
689 nickname to the one giving the NICK command. If unformatted
690 nickname is cached already it will be formatted and the
691 local entry will always get the unformatted nickname.
692 Affected file lib/silcclient/idlist.c.
694 * Fixed some double frees from client library commands.
695 Affected file is lib/silcclient/command.c.
697 * Fixed CUMODE command in server to assure that no one can
698 change founder's mode than the founder itself, there was a
699 little bug. Affected file silcd/command.c.
701 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
703 * Removed the SilcClientCommandDestructor from the client
704 libary, it is not needed anymore. Affected files are
705 lib/silcclient/silcapi.h, command[_reply].[ch],
706 client_notify, idlist.c.
708 * Fixed GETKEY command to first resolve client, and then
709 resolve the server only if the client was not found, instead
710 of resolving both at the same time. Affected file is
711 lib/silcclient/command.c.
713 * Added silc_client_start_key_exchange_cb and lookup the
714 remote hostname and IP address before starting the key
715 exchange with server. The affected file is
716 lib/silcclient/client.c.
718 * The server's public key is now saved using the IP address
719 of the server and not the servername for the filename.
720 The hostname public key filename is checked as an fall back
721 method if the IP address based filename is not found.
723 Fixed the GETKEY command to save the fetched server key
726 Print the remote server's hostname now when new key is
727 received during connection process. Affected file is
728 irssi/src/silc/core/client_ops.c.
730 * Return always our own public key to the client if it asks
731 for it with GETKEY command. Affected file silcd/command.c.
733 * Removed the use_auto_addr variable from default config
734 file since it was in wrong section. Affected file is
737 * Fixed TOPIC_CHANGE notification to not route it when it
738 was sent using silc_server_send_notify_to_channel function.
739 Affected file silcd/command.c.
741 * Fixed silc_server_send_notify_kicked to send the kicker's
742 Client ID also, it was missing. Affected files are
743 silcd/command.c, silcd/packet_send.[ch].
745 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
747 * Do not save client history information in SERVER_SIGNOFF.
748 Fixes the bug in normal server that it does not detect
749 the client becoming valid after the server becomes back
750 online. Affected file silcd/server_util.c.
752 * Added `sock_error' field into the SilcSocketConnection
753 context. When error occurs during socket operation (read
754 or write) the error is saved. Added also new function
755 silc_socket_get_error to return human readable socket error
756 message. Affected files are lib/silcutil/silcsockconn.[ch],
757 lib/silcutil/unix/silcunixsockconn.c, and
758 lib/silcutil/win32/silcwin32sockconn.c.
760 * The server now prints the socket error message in the
761 signoff for client. Affected file silcd/server.c.
763 * Fixed the `created' channel information sending from router
764 to server in JOIN command. Checks now whether the channel
765 really was created or not and set it according that.
767 Fixed the JOIN command to use the client entry's current
768 ID during the joining procedure instead of the one it sent
769 in the command (it is checked though), since it can change
770 between the packet processing and command processing, and
771 would just case unnecessary pain in the client end. Affected
772 file silcd/command.c.
774 * Fixed a channel key payload sending to use correct channel
775 ID when the server was forced to change the channel's ID by
776 router. Router sent the key payload with the old Channel ID.
777 Affected file silcd/packet_receive.c.
779 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
781 * Call silc_server_save_channel_key only if the key payload
782 was provided in the JOIN command's command reply. Affected
783 file silcd/command_reply.c.
785 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
787 * Fixed silc_mp_sizeinbase to return the value correctly with
788 MPI. Affected file lib/silcmath/mp_mpi.c.
790 * Fixed the stop_server signal to correctly stop the scheduler
791 and gracefully stop the server when SIGTERM or SIGINT signals
792 are received. Affected file silcd/silcd.c.
794 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
796 * Simple handling of TERM and HUP signals. Also added some log
797 flushing call around. Affected file is
800 * Fixed small bugs in silclog.c. Now buffering output will take
801 effect after 10 seconds since startup: This will ensure that
802 no important startup messages are lost. Also output redirection
803 will preserve original format ([Date] [Type] message).
804 Affected file is lib/silcutil/silclog.c.
806 * Added two options to the config file, in the logging section:
807 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
808 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
810 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
812 * Do not print the warning about log files not being initialized
813 more than once to avoid excess logging. Affected file is
814 lib/silcutil/silclog.c.
816 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
817 the SIM copying in make install in Makefile.am.pre.
819 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
821 * Rewritten silclog APIs. Globally interesting changes follows:
822 silc_log_set_files() changed to silc_log_set_file().
823 silc_log_set_callbacks() changed to silc_log_set_callback().
824 ROBOdoc documented silclog header file.
825 SilcLogCb now returns bool to wether inihibit the default
826 handler or not (to keep the old behaviour return always TRUE).
827 The new APIs should also fix the problem of the
828 silcd_error.log file that was written in the current directory.
831 Log files streams will remain opened after silc_log_set_file()
832 call, means less CPU usage notably on high traffic servers.
833 File streams are now full buffered, and flushed to the disk
834 every 5 minutes, lesses HD activity and CPU usage.
835 Messages can be redirected, allowing admins to configure
836 one single logfile for all server messages.
837 the silc_log_quick global variable to activate fast-logging.
838 Affected files lib/silcutil/silclog.[ch]
840 * Changed some code to conform new silclog APIs. Affected
841 files are doc/example_silcd.conf.in, silcd/server.c
842 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
845 * Fixed a memory leak that could occur in some situations.
846 Affected file silcd/serverconfig.c.
848 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
850 * Added the silc_client_del_client to remove the client from
851 all channels as well. Affected file lib/silcclient/idlist.c.
853 * Fixed the client library to correctly remove the client
854 from all channels when the client entry is being destroyed.
855 Affected file lib/silcclient/client_notify.c, command.c.
857 * Added auto-nicking support to the client library. If the
858 applicatio now sets client->nickname it will be sent to the
859 server after connecting by the library. This way for example
860 SILCNICK (or IRCNICK) environment variables will have effect
861 and always change the nickname automatically to whatever
862 it is wanted. Affected file lib/silcclient/client.[ch].
864 * Renamed silc_server_command_bad_chars to the
865 silc_server_name_bad_chars and moved it to the
866 silcd/server_util.[ch]. Added also new function
867 silc_server_name_modify_bad to return nickname that
868 includes bad characters as new nickname without those
869 bad characters. This check and modify is now used in
870 silc_server_new_client when the username is initially set
871 as nickname, so it must be checked to be valid nickname.
872 Affected file silcd/packet_receive.c.
874 * The nickname length is now taken from the packet for real
875 and not trusted to strlen() since it clearly can return
876 wrong length for nickname including bad characters. This
877 also applies to channel names. Affected file silcd/command.c.
879 * Removed the lib/silcsilm/modules directory. Modules are now
880 compiled into the lib/silcsim. Fixed the copying of the
881 modules to follow symbolic links in Makefile.am.pre.
883 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
885 * Fixed silc_string_regexify list creation. Fixes bugs with
886 BAN and INVITE commands in server. The affected file is
887 lib/silcutil/unix/silcunixutil.c.
889 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
891 * Removed the command destructor entirely from the server's
892 command and command reply routines. It is not needed, and
893 its usage was buggy and caused crashes. Affected files are
894 silcd/command[_reply].[ch].
896 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
898 * Cancel protocol and NULL sock->protocol if timeout
899 occurred during protocol. Affected file silcd/server.c.
901 * Cancel protocol timeouts always before calling the final
902 callback, to assure that after final callback is called
903 no other state will be called for the protocol anymore.
904 Affected file silcd/protocol.c.
906 * Print error log if incoming connection configuration could
907 not be found. Affected file silcd/server.c.
909 * Fixed JOIN command to correctly save the founder mode
910 to the client on normal SILC server, when the channel
911 was created by the router. Affected file silcd/command.c.
913 * Fixed LIST command (hopefully) to send correct reply
914 packets. Affected file silcd/command.c.
916 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
918 * The silc_packet_receive_process now returns FALSE if the
919 read data was invalid packet, and TRUE if it was ok.
921 The server now checks that if unauthenticated connection
922 sends data and its processing fails the server will close
923 the connection since it could be a malicious flooder.
925 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
927 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
929 * Make sure the warning about error opening a log file is
930 printed only once and not everytime it fails (produces
931 too much useless log). Affected file lib/silcutil/silclog.c.
933 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
935 * Made the silc_server_daemonise() function more readable.
936 Affected file silcd/server.c.
938 * Pid file is now optional, the user may comment it out from
939 the config file. Removed define SILC_SERVER_PID_FILE, we
940 don't need a default any longer. Affected file
941 configure.in.pre, lib/Makefile.am.pre.
943 * Make some use of the pid file. The server now dies at startup
944 if it detects a valid pid file on his path. The server would
945 die anyway in this circumstance, because of the bind() failure.
946 Affected file silcd/silcd.c.
948 * No longer compiling lib/dotconf.
950 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
952 * Fixed JOIN command parsing not to crash. Affected file
953 lib/silcclient/command.c.
955 * Fied the NICK_CHANGE notify to add the new client entry
956 even it is resolved. This removes an <[unknown]> nick
957 thingy bug in the client. Affected file is
958 lib/silcclient/client_notify.c.
960 * Do not try to allocate 0 bytes (efence does not like it)
961 in lib/silccore/silccomand.c when encoding payload.
963 * Do not take IRCNICK as nickname in Irssi SILC client since
964 it is not possible to set nickname before hand connecting
965 the server (TODO has an entry about adding auto-nicking
968 * Changed the silc_server_command_pending to check whether
969 there already exists an pending entry with the specified
970 command, command identifier and pending callback. This is
971 to fix IDENTIFY and WHOIS related crashes that may register
972 multiple pending commands with same identifier. Affected
973 file silcd/command.c.
975 * Fixed the server to reconnect to the router even if it
976 was already reconnecting and EOF was received. This to
977 fix a possibility that the server wouldn't ever try to
978 auto-reconnect to the router. Affected file silcd/server.c.
980 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
982 * Fixed the server's password authentication to use the
983 length of the locally saved password, and not the one
984 sent in the packet. Affected file silcd/protocol.c.
986 * Fixed same password authentication problem in the
987 Authentication Payload handling routines in
988 lib/silccore/silcauth.c.
990 * Yet another password authentication problem fixed with
991 channel password handling in silcd/command.c.
993 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
995 * If first character of string in silc_parse_userfqdn is '@'
996 then do not parse it. Affected file is
997 lib/silcutil/silcutil.c.
999 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1001 * Fixed minor bug in IDENTIFY command reply sending, which
1002 caused various weird problems during JOIN when it was
1003 resolving names for users. Affected file silcd/command.c.
1005 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1007 * Fixed the IDENTIFY command reply sending to chech better valid
1008 clients. It was possible to send incomplete list of replies.
1009 Affected file silcd/command.c.
1011 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1013 * Added silc_client_command[s]_[un]register functions now to
1014 dynamically register the commands in client library. Removed
1015 the static table of commands. This allows the client library
1016 to call commands without causing the application to know about
1017 what commands library has called.
1019 Removed the INFO command reply kludge to detect when the command
1020 was called by library. Now library use its own command reply
1021 function for INFO command.
1023 Added function silc_client_command_call to call a command.
1024 Application can use it to call command, not access the structure
1027 Now all commands that are sent by the client library (not
1028 explicitly sent by application) use own command reply functions.
1030 Affected files around lib/silcclient/ and in
1031 irssi/src/silc/core/.
1033 * Fixed the WHOIS command reply sending to chech better valid
1034 clients. It was possible to send incomplete list of replies.
1036 Fixed the WHOIS and IDENTIFY to send the request to router
1037 if normal server did not do it and did not find any results.
1039 Affected file silcd/command.c.
1041 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1043 * Moved the internal data from SilcClient context into its
1044 own file, not accesible to application. Affected files
1045 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1046 and other files in client library.
1048 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1050 * Added doc/examples installation target in Makefile.am.pre.
1053 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1055 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1056 commands the found client entry will be removed from the
1057 cache, after notifying application about the error. Affected
1058 file lib/silcclient/command_reply.c.
1060 * Changed the /MSG to check for exact nickname user gave, and
1061 not let `nick' match `nick@host' if it is only one found. Now,
1062 user must type the exact nickname (like nick@host2) even if
1063 there are no more than one same nicks found. This is to avoid
1064 a possibility of sending nickname to wrong nickname since
1065 `nick' could match `nick@host'. Affected file is
1066 irssi/src/core/silc-servers.c.
1068 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1070 * Do not print "you are now server operator" or similar when
1071 giving /away command. Affected files are
1072 irssi/src/silc/core/client_ops.c, silc-servers.h.
1074 * Made the silc_server_command_pending_error_check to send
1075 the same command reply payload it received back to the
1076 original sender of the command. This way all arguments
1077 that was received by the server will be received by the
1078 client too. Affected file silcd/command.c.
1080 * Added the silc_idcache_add to return the created cache entry
1081 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1083 * Add global clients to expire if they are not on any channel.
1084 This is because normal server will never know if they signoff
1085 if they are not on any channel. The cache expiry will take
1086 case of these entries. This is done by normal servers only.
1087 The affected files are silcd/command_reply.c,
1088 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1090 * If server receives invalid ID notification for WHOIS or
1091 IDENTIFY and the ID exists in the lists, it is removed.
1092 Affected file silcd/command_reply.c.
1094 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1095 in client then client entry that it matches is searched and
1096 the nickname is printed on the screen for user. Affected
1097 file irssi/src/silc/core/client_ops.c.
1099 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * Use cache entry expire time in the LIST command reply to
1102 purge old entries from the cache after the LIST command
1103 reply has been received. This way we don't have non-existent
1104 entries in the cache for too long. Affected file is
1105 silcd/command_reply.c.
1107 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1109 * If we are normal server, and we've not resolved client info
1110 in WHOIS or IDENTIFY from router, and it is global client,
1111 we'll check whether it is on some channel. If it is not
1112 then we cannot be sure about its validity and will resolve it
1113 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1114 file silcd/command.c.
1116 * Search channel by name (if possible) rather than by ID
1117 in IDENTIFY command's command reply. Affected file is
1118 silcd/command_reply.c.
1120 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1123 Updated specs and implemented it. Affected file silcd/command.c,
1124 silcd/packet_send.c and silcd/packet_receive.c.
1126 * Implemented the <founder auth> payload handling in the JOIN
1127 command. If provided all conditions for channel joining
1128 except requirement to provide correct passphrase can be
1129 overrided by the channel founder. Updated the protocol specs.
1130 Affected file silcd/command.c.
1132 Added support for founder auth in JOIN command in client
1133 library. Fixed the parsing of the JOIN command now to support
1134 all options as they should be. The affected file is
1135 lib/silcclient/command.c.
1137 * Optimized the WHOIS and IDENTIFY commands to send the request
1138 to router only if it includes nicknames or other names. If
1139 they include only IDs then check the local cache first before
1140 routing. Affected file is silcd/command.c.
1142 * Added channels topic announcements. Affected file is
1143 silcd/packet_receive.c and silcd/server.c.
1145 * Fixed the silc_server_send_notify_topic_set to really destine
1146 the packet to channel. Affected file silcd/packet_send.c.
1148 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1149 library. Affected file lib/silcclient/client_notify.c.
1151 * Added UMODE announcements. Affected file silcd/server.c.
1153 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1155 * Memory leak fixes in:

1162 lib/silccore/silccommand.c
1163 lib/silccore/silcidcache.c
1168 * ROBOdoc documented the lib/silcske/groups.h file and a
1169 bit changed the interface for better.
1171 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1173 * Update the client entry context in the ID cache after
1174 nick change. Affected file lib/silcclient/command.c.
1175 Fixes the CUMODE command when regaining founder privileges,
1176 and a little WHOIS problem.
1178 * Fixed silc_net_gethostbyname to correctly call the
1179 inet_ntop. Affected file lib/silcutil/silcnet.c.
1181 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1183 * Added IPv6 support checking to the configure.in.pre, added
1184 also --enable-ipv6 option to override the check. Affected
1185 file configure.in.pre.
1187 * The silc_thread_create now calls the start function
1188 directly if threads support is not compiled in. Removes
1189 ugly #ifdef's from generic code. Affected files are
1190 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1192 * Added silc_net_gethostby[name/addr]_async to asynchronously
1193 resolve. Affected files are lib/silcutil/silcnet.[ch].
1195 * Added support for rendering IPv6 based server, client and
1196 channel IDs. Affected file lib/silcutil/silcutil.c.
1198 * Added support for creating IPv6 based server IDs. Affected
1199 file is silcd/serverid.c.
1201 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1203 * Added silc_net_gethostby[addr/name] into the
1204 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1205 routines. Added silc_net_is_ip[4/6]. Affected file is
1206 lib/silcutil/unix/silcunixnet.c. All routines that take
1207 address as argument now supports both IPv4 and IPv6 addresses.
1209 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1211 * Fixed LIST command reply sending in server. Affected file
1214 * Server now sends the kicker's client ID in the KICK notify
1215 to the kicked client. Affected file silcd/command.c.
1217 * The client library now parses the kickers client ID and
1218 UI displays it. Affected files lib/silcclient/client_notify.c
1219 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1221 * Made all payload parsing function prototypes consistent.
1222 They all take now const unsigned char * and uint32 pair as
1223 the payload data instead of SilcBuffer. Changes all around
1224 the source tree. Other unsigned char* -> const unsigned char*
1225 changes around the tree as well.
1227 * Optimized SFTP client and server packet sending not to
1228 allocate new buffer for each packet but to recycle the
1229 first allocated buffer. Affected files are
1230 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1232 * Optimized the SFTP client to use SilcList instead of
1233 SilcDList for requests, because it is faster. Affected file
1234 is lib/silcsftp/sftp_client.c.
1236 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1237 into lib/silccore/silcid.[ch].
1239 Renamed silcpayload.[ch] into silcargument.[ch].
1241 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1243 * If client entry is deleted with active key agreement
1244 session, abort the session.
1246 The silc_client_abort_key_agreement now calls the completion
1247 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1249 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1252 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1254 * Don't use __restrict in older GCC's. Affected file is
1255 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1257 * silc_net_localhost now attempts to reverse lookup the
1258 IP/hostname. Affected file lib/silcutil/silcnet.c.
1260 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1261 command. It can be used to gain founder privileges at
1262 the same time when joining the channel.
1264 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1265 kicker's client ID as well. Updated protocol specs.
1267 Defined that the server must send SILC_COMMAND_IDENTIFY
1268 command reply with error status to client who sent
1269 private message with invalid client ID.
1271 Updated the protocol specification.
1273 * Added silc_server_send_command_reply to send any
1274 command reply. Affected file silcd/packet_send.[ch].
1276 * Added silc_id_payload_encode_data to encode ID payload
1277 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1279 * The server now send IDENTIFY command reply with error
1280 status if client ID in private message is invalid. Affected
1281 file silcd/packet_receive.c.
1283 * Save the server key file with server's IP address in
1284 the filename instead of hostname. The affected file is
1285 irssi/src/silc/core/client_ops.c.
1287 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1289 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1292 * Added libtool support for compiling shared objects in
1293 lib/silcsim. Affected file configure.in.pre and
1294 lib/silcsim/Makefile.am. Original patch by cras.
1296 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1298 * Pid file configuration, and server's config file fixes
1299 patch by toma. Updated CREDITS file.
1301 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1303 * Fixed silc_client_channel_message to not try to decrypt
1304 the message twice if it resolved the destination client
1305 information. This could cause of dropping one channel
1306 message. Affected file lib/silcclient/client_channel.c.
1308 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1311 lib/silcclient/client.c. This function is used when the SILC
1312 Client is run under some other scheduler, or event loop or
1313 main loop. On GUI applications, for example this may be
1314 desired to used to run the client under the GUI application's
1315 main loop. Typically the GUI application would register an
1316 idle task that calls this function multiple times in a second
1317 to quickly process the SILC specific data.
1319 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1321 * Fixed silc_server_drop() for dropping the supplementary
1322 groups as well, this could cause a security hole on some
1325 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1330 * Write PID file after dropping privileges. Added -F option
1331 to run server on foreground. A patch by debolaz.
1332 Affected files silcd/server.c, silcd/silcd.c.
1334 * Fixed MOTD to return the MOTD file server name. Affected
1335 file silcd/command.c.
1337 * Added INFO command reply handling to the Irssi SILC Client.
1338 Affected file irssi/src/silc/core/client_ops.c.
1340 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Fixed the silc_idcache_list_* routines to really support
1343 the dynamic list. Fixes a crash. Affected file is
1344 lib/silccore/silcidcache.c.
1346 * Fixed the LIST command reply to really call LIST command's
1347 pending callbacks. Affected file silcd/command_reply.c.
1349 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1351 * Update conn->local_entry->nickname after giving NICK
1352 command. Affected file lib/silcclient/command.c.
1354 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1356 * Added the [pid] option to the silcd configuration file
1358 Affected files: serverconfig.[ch] and silcd.c
1360 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1362 * Save fingerprint in WHOIS command reply in server.
1363 Affected file silcd/command_reply.c.
1365 * Fixed NICK commands pending callback registration.
1366 Affected file lib/silcclient/command.c.
1368 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * Use ++server->cmd_ident when sending commands in server,
1371 instead of random number. Affected file silcd/command.c.
1373 * Fixed GETKEY command reply to call actually GETKEY pending
1374 command callbacks. Affected file silcd/command_reply.c.
1376 * A bit stricter check for nicknames. Check for same nickname
1377 in NICK command also. Affected file silcd/command.c.
1379 * Do not call INFO command everytime client ID changes, only
1380 during first connecting. Affected file lib/silcclient/client.c.
1382 * Set the new nickname only after successful command reply for
1383 NICK command is returned by server. Affected file
1384 lib/silcclient/command.c.
1386 * Remove nicknames from nicklist during server_signoff notify.
1387 Should fix /NAMES bit more. The affected file is
1388 irssi/src/silc/core/silc-channels.c.
1390 * Added `fingerprint' field to the SilcIDListData in the
1391 silcd/idlist.h to hold the fingerprint of the client's
1394 Send the fingerprint of the client's public key in WHOIS
1397 Affected files silcd/command.c, and silcd/idlist.[ch].
1399 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1400 create fingerprint from given data.
1402 * Show the fingerprint of the client's public key in WHOIS.
1403 Affected files irssi/src/module-formats.[ch] and
1404 irssi/src/silc/core/client_ops.c.
1406 * Format the multiple same nicknames also during JOIN and
1407 NICK_CHANGE notifys. Affected file is
1408 lib/silcclient/client_notify.c.
1410 * Do not print error on screen for invalid private message
1411 payload since it can come if someone is sending private
1412 messages with wrong key. Affected file
1413 lib/silccore/silcprivate.c.
1415 * Fixed multiple concurrent /PING crash. Affected file
1416 lib/silcclient/command.c.
1418 * Changed the wrong ID encoding. All IP addresses must be
1419 in MSB first order in encoded format. They were encoded
1420 wrong and was in LSB format. Affected files are
1421 silcd/serverid.c, lib/silcutil/silcutil.c.
1423 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1425 * Call the `connect' client operation through the scheduler
1426 in case of error. Affected file lib/silcclient/client.c.
1428 * Call the `failure' client operation even if the error
1429 occurred locally during a protocol. Affected file is
1430 lib/silcclient/protocol.c.
1432 * Added support of sending LIST command to router from normal
1433 server. This way normal server can get list of all channels
1434 in the network too. Fixed the channel list sending in the
1435 server too. Affected files are silcd/command.c, and
1436 silcd/command_reply.[ch].
1438 * Added silc_server_update_channels_by_server and
1439 silc_server_remove_channels_by_server. They are used during
1440 disconnection of primary router and in backup router protocol.
1441 Affected file silcd/server_util.[ch], silcd/server.c and
1442 silcd/server_backup.c.
1444 * Fixed channel adding to global list in IDENTIFY command
1445 reply in server. Affected file silcd/command_reply.c.
1447 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1449 * If the incoming packet type is REKEY or REKEY_DONE process
1450 that packet always synchronously. Fixes yet another MAC
1451 failed error on slow (dialup) connections. Affected file
1452 lib/silcclient/client.c and silcd/server.c.
1454 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1456 * Call check_version SKE callback for initiator too. Affected
1457 file lib/silcske/silcske.c.
1459 * Implemented fix for security hole found in the SKE that was
1460 fixed in the specification few days back; the initiator's
1461 public key is now added to the HASH value computation.
1462 Added backwards support for the old way of doing it too, for
1463 old clients and old servers. Affected file is
1464 lib/silcske/silcske.c.
1466 * Enabled mutual authentication by default in SKE. If initiator
1467 is not providing mutual authentication the responder will
1468 force it. This will provide the proof of posession of the
1469 private key for responder. The affected files are
1470 lib/silcclient/protocol.c and silcd/protocol.c.
1472 * Do not cache anymore the server's public key during SKE.
1473 We do mutual authentication so the proof of posession of
1474 private key is done, and if the server is authenticated in
1475 conn auth protocol with public key we must have the public
1476 key already. Affected file silcd/protocol.c.
1478 * Added new global debug variable: silc_debug_hexdump. If
1479 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1480 file lib/silcutil/silclog.[ch].
1482 * Fixed compilation warning due to char * -> const char *.
1483 Affected files lib/silcutil/silcnet.h, and
1484 lib/silccore/silcauth.[ch].
1486 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1488 * Fixed CMODE command when new channel key was created. If
1489 the creation failed the old key was removed. Next time giving
1490 same command would crash the server since the old key was
1491 freed already. Affected file silcd/command.c.
1493 * Fixed the silc_server_announce_get_channels to not crash
1494 on reconnect. Affected file silcd/server.c.
1496 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1498 * Added silc_log_set_debug_string function to set a regex
1499 string to match for debug output. Only the function names,
1500 or filenames matching the given debug string is actually
1501 printed. This way it is possible to filter out those debug
1502 strings that user is not interested in.
1504 Fixed a bug in silc_string_regexify.
1506 Affected files lib/silcutil/silclog.[ch], and
1507 lib/silcutil/unix/silcunixutil.c.
1509 * Changed the -d options in both server and Irssi SILC client
1510 to take the debug string as argument. Affected files
1511 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1513 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1515 * Added silc_hash_babbleprint to create a Bubble Babble
1516 Encoded fingerprint. The encoding is developed by Antti
1517 Huima (draft-huima-babble-01.txt), and it creates human
1518 readable strings out of binary data. Affected file
1519 lib/silccrypt/silchash.[ch].
1521 * Print the babble print now in addition of fingerprint as well
1522 in Irssi SILC client. Affected files are
1523 irssi/src/fe-common/silc/module-formats.[ch],
1524 irssi/src/fe-common/silc/core/client_ops.c.
1526 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Fixed a security problem found in SKE. The initiator's
1529 public key too is now added to the HASH hash value creation
1530 which is signed by the responder to create the SIGN value.
1531 This will prevent anyone in the middle to lie to the responder
1532 about the initiator's public key. If this is done now, the
1533 man in the middle will get caught. Updated the protocol
1536 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Better installation directory handling. Configure module
1539 paths and other paths automatically to example_silc* files
1540 in doc/. A patch by toma.
1542 * Fixed compiler warning from MPI library, and from SILC RNG.
1545 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1546 It can be configured with ./configure. A patch by toma.
1548 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1550 * Find correct make to use in prepare-clean. A patch by
1551 toma. Affected file prepare-clean.
1553 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1555 * Added irssi variables use_auto_addr, auto_bind_ip,
1556 auto_bind_port and auto_public_ip.
1558 * Changed the interface for silc_client_send_key_agreement
1559 in lib/silcclient/silcapi.h
1563 irssi/src/silc/core/silc-core.c
1565 lib/silcclient/silcapi.h
1566 irssi/src/silc/core/silc-channels.c
1567 lib/silcclient/client_keyagr.c
1570 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Added silc_pkcs_public_key_compare to compare two
1573 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1575 * Check that the client who set the founder mode on the
1576 channel is the same client that is giving the founder
1577 mode to itself. It is done by comparing the saved public
1578 key (it is saved even in the authentication is passphrase).
1579 Affected file silcd/command.c.
1581 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1583 * Do not process packet for disconnected socket connection.
1584 Affected file lib/silccore/silcpacket.c.
1586 * Process the DISCONNECT packet through scheduler in the
1587 client library. Affected file lib/silcclient/client.c.
1589 * Fixed the silc_client_packet_parse to not to increase
1590 the packet sequence number if the conn->sock and the
1591 current socket connection is not same. This can happen
1592 for example during key agreement when the conn includes
1593 multiple socket connections (listeners). Affected file
1594 lib/silcclient/client.c.
1596 * The sender of the file transfer request now provides also
1597 the pointer (listener) for the key exchange protocol. If
1598 the listener cannot be created then it sends empty key
1599 agreement and lets the receiver provide the listener.
1601 Added `local_ip' and `local_port' arguments to the
1602 silc_client_file_send. If they are provided they are used,
1603 if not then it will attempt to find local IP address, if
1604 not found or bind fails then the remote client will provide
1607 Affected files are lib/silcclient/client_ftp.c and
1608 lib/silcclient/silcapi.h.
1610 * Extended the FILE SEND command to support defining the
1611 local IP and port for key exchange listener. They are
1612 optional. Affected file irssi/src/silc/core/silc-servers.c.
1614 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1616 * Defined to WHOIS command reply the sending of fingerprint
1617 of the client's public key (if the proof of posession of the
1618 corresponding private key is verified by the server).
1619 Updated to the protocol specification.
1621 * Added support of receiving the client's public key's
1622 fingerprint in command reply in client library. Affected
1623 file is lib/silcclient/command_reply.c, and
1624 lib/silcclient/idlist.[ch].
1626 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1628 * Do not send over 128 chars long nickname to the server
1629 in NICK command. Affected file lib/silcclient/command.c.
1631 * Do not send over 256 chars long channel names to the server

1683 preserve the WHOWAS info for the client. Affected file
1684 silcd/server_util.c.
1686 * Fixed SERVER_SIGNOFF notify handling in the server. The
1687 server is now able to process incoming SERVER_SIGNOFF notify
1688 for a server that it doesn't even know about. It will remove
1689 the clients provided in the notify. Affected file
1690 silcd/packet_receive.c.
1692 * Check for partial packet in data queue after every packet that
1693 was found from the queue. Return and wait for more data if
1694 there is partial data in queue. Affected file is

1712 irssi/src/fe-common/silc/module-formats.[ch].
1714 * Wrote a help file for FILE command.
1716 * Added silc_rng_global_get_byte_fast to get not-so-secure
1717 random data as fast as possible. Random data is read from
1718 /dev/urandom if available and from the SILC RNG if not
1719 available. It is used in padding generation. Affected file
1720 lib/silccrypt/silcrng.[ch].
1722 * All packets in client library are now processed synchronously.
1723 Optimized packet processing a lot. Affected file
1724 lib/silcclient/client.c.

1735 * Assure that silc_client_notify_by_server_resolve does not
1736 resolve the client information multiple times. If it cannot
1737 be found by the first it cannot be found at all. Affected
1738 file lib/silcclient/client_notify.c.
1740 * Fixed WHOWAS command reply calling. Affected file
1741 lib/silcclient/command_reply.c.
1743 * Removed all references to silc_idlist_get_client from the
1744 Irssi SILC client since that call is internal call used by
1745 the library. The Irssi SILC client will use now client
1746 retrieval functions found in silcapi.h.
1748 * Fixed a bug in resolving nickname info before sending
1749 private message. It used freed memory. Affected file
1750 irssi/src/silc/core/silc-servers.c.
1752 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1754 * Assure my_channels statistics cannot go negative in server.
1755 Affected files silcd/server.c, silcd/server_util.c.

1771 * Added silc_net_localip to return local host's IP address.
1772 Affected file lib/silcutil/silcnet.[ch].
1774 * If key exchange or rekey protocol is active for a connection
1775 parse all packets syncronously since there might be packets
1776 in packet queue that we are not able to process without first
1777 processing packets before them. Affected file silcd/server,
1778 lib/silcclient/client.c.
1780 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1781 whether library should continue processing the packet.
1782 Affected file lib/silccore/silcpacket.h.

1828 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1829 is incomplete and is being resolved, it won't be resolved
1832 Make sure also that USERS command reply does not resolve
1833 twice information. Affected file is
1834 lib/silcclient/command_reply.c.
1836 Make sure that silc_client_get_clients_by_list does not
1837 resolve twice same information.
1839 * Check for valid client->id in the silc_server_free_client_data.
1840 Affected file silcd/server.c.
1842 * Fixed /GETKEY nick@server not to crash if the server entry
1843 is not found. Affected file lib/silcclient/command.c.
1845 * Fixed the silc_server_check_cmode_rights to check the

1851 Affected file silcd/command.c.
1853 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1855 * Call the silc_server_udpate_servers_by_server in the
1856 primary router that comes back online in the backup resuming
1857 protocol. Otherwise it routes packets wrong. Affected file
1858 silcd/server_util.[ch], silcd/server_backup.c.
1860 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1862 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1863 lib/silcutil/silcbuffmt.[ch].
1865 * Redefined the SILC packet header to include the padding
1866 length. Affected file lib/silccore/silcpacket.[ch].
1868 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1869 length for maximum padding up to 128 bytes). Affected
1870 file lib/silccore/silcpacket.h.
1872 * Removed all backwards support for old 0.5.x MAC thingies.
1873 The SILC packet header change makes it impossible to be
1874 backwards compatible.
1876 * Send the ENDING packet with timeout in the backup resuming
1877 protocol. This is to assure that all routers has connected
1878 to the primary router. Affected file silcd/server_backup.c.
1880 * Changed the RNG to take the first IV from random data. It
1881 used to take it from zero actually. Changed the RNG also
1882 to use /dev/urandom during session. /dev/random is used
1883 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1885 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1887 * Changed the SILC packet header to have the first two bytes
1888 (the packet length) encrypted. Affected files aroung the
1889 code tree, lib/silccore/silcpacket.[ch]. Removed the
1890 SilcPacketCheckDecrypt callback. It is not needed anymore
1891 since the silc_packet_receive_process will determine now
1892 whether the packet is normal or special.
1894 * Implemented the unidirectional MAC keys. Affected files
1895 lib/silcske/silcske.c, silcd/protocol.c and
1896 lib/silcclient/protocol.c.
1898 * Implemented the packet sequence number to the MAC computation.
1899 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1900 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1901 lib/silcclient/protocol.c.
1903 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * Allow backup router to announce servers. All servers
1906 announced by backup router are added to the global list
1907 automatically. Update hte server's socket to our primary
1908 router also when backup router announces a server.
1909 Affected file silcd/packet_receive.c.
1911 * Do not update the client->router in the function
1912 silc_server_udpate_clients_by_server if the client is on
1913 global list. We might fail to find any specific server
1914 for locally connected clients and local cell clients. They
1915 should still use the `from' and not `to' as client->router.
1916 This fixes backup router resuming protocol. Affected file
1917 silcd/server_util.c.
1919 * Decrease channel statistics count only if the channel
1920 deletion worked. Affected files are silcd/server.c and
1921 silcd/server_util.c.
1923 * Added silc_server_update_servers_by_server to update origin
1924 of all server entries. Used during backup router protocol.
1925 Affected files silcd/server_util.[ch], silcd/server.c. and
1926 silcd/backup_router.c.
1928 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1929 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1930 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1931 lib/silccrypt/silchmac.c.
1933 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * Assure that router cannot reroute the same channel message
1936 to the sender. Affected file silcd/packet_receive.c.
1938 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * Made better checks that the channel message is not sent
1941 to the router it came from. Affected file is
1942 silcd/packet_send.c. Fixed memory leak too.
1944 * Announce informations for incoming router connection, but
1945 only after checking if it is replaced by backup router.
1946 Affected file silcd/packet_receive.c.
1948 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1950 * Fixed the backup resuming protocol to work in multiple
1951 router environment. Affected file silcd/server_backup.c.
1953 * Route packet only to one router in the function
1954 silc_server_packet_send_to_channel. Affected file is
1955 silcd/packet_send.c.
1957 * Fixed silc_server_send_notify_dest to set the broadcast
1958 flag. Fixed the silc_server_send_notify_topic to actually
1959 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1960 Affected file silcd/packet_send.c.
1962 * Changed the SFTP Filesystem interface. Changed the
1963 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1964 the filesystem operation function. The SilcSFTPFilesystem
1965 is now a context that is allocated by all filesystem allocation
1966 functions and it already includes the operations structure
1967 and filesystem specific context. It is given as argument
1968 now to the silc_sftp_server_start. This made the interface
1969 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1970 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1972 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1974 * Changed the backup router adding and getting interfaces
1975 in the server. The router that will be replaced by the
1976 specified backup router is now sent as argument. Affected
1977 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1980 * Added silc_net_addr2bin_ne to return the binary form of
1981 the IP address in network byte order. Affected files
1982 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1984 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1986 * Check for existing server ID in silc_server_new_server
1987 and in silc_server_connect_to_router_final and remove the
1988 old entry if it exists. Affected file silcd/packet_receive.c,
1991 * Send the channel message always to only one router, either
1992 in upstream or downstream. Affected file is
1993 silcd/packet_send.c.
1995 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Wrote the definition of the backup resuming protocol to the
1998 protocol specification.
2000 * Removed one redundant channel key generation from normal
2001 server during joining procedure. Removed one redundant
2002 channel key sending from server to router during joining
2003 procedure. Affected file silcd/command.c.
2005 * Made minor bugfixes to the backup router resuming protocol.
2006 Affected file silcd/server_backup.c, server.c.
2008 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Added --disable-asm configuration option. Affected files
2011 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2014 * Implemented the backup resuming protocol that is used to
2015 resume the primary router position in the cell after the
2016 primary router comes back online. Affected files
2017 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2018 and silcd/server_util.[ch].
2020 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Sleep two (2) seconds after sending QUIT command to server.
2023 Affected file lib/silcclient/command.c.
2025 * Assure that if outgoing data buffer is pending do not force
2026 send any data. Affected file silcd/packet_send.c.
2028 * Assure that if outgoing data buffer is pending do not force
2029 send any data. Affected file lib/silcclient/client.c.
2031 * Implemented the backup router support when the primary router
2032 goes down. The servers and routers can now use the backup
2033 router as new primary router without loosing connectivity.
2035 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2038 in the server to indicate disabled entry. All data read
2039 from the connection will be ignored and no data is sent
2040 for entry that is disabled. Affected files are
2041 silcd/idlist.h, silcd/server.c.
2043 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Created SFTP client and server test programs in the
2046 lib/silcsftp/tests directory.
2048 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2050 * Implemented memory filesystem (virtual filesystem) for
2051 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2054 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2056 * Implemented the SFTP (SSH File Transfer Protocol) to the
2057 lib/silcsftp. It includes SFTP client and SFTP server
2060 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2062 * Moved lib/silccore/silcprotocol.[ch] to the
2063 lib/silcutil library.
2065 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2066 take variable argument list pointer as argument. Affected
2067 file lib/silcutil/silcbuffmt.[ch].
2069 * Added silc_buffer_set function that is used to set data
2070 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2071 Affected file lib/silcutil/silcbuffer.h.
2073 * Changed various routines in the core library to use the new
2074 silc_buffer_set instead of allocating new buffer only for
2077 * Added 64-bit value formatting and unformatting support to the
2078 silc_buffer_[un]format routines. Affected file is
2079 lib/silcutil/silcbuffmt.[ch].
2081 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2082 to includes/bitmove.h.
2084 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2086 * Fixed channel user mode saving in client library. Affected
2087 file lib/silcclient/command[_reply].c.
2089 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Defined the file transfer to the SILC Protocol. Added
2092 new packet type SILC_PACKET_FTP and defined File Transfer
2093 Payload. The mandatory file transfer protocol is SFTP
2094 (SSH File Transfer Protocol). Affected file in addition
2095 of the internet draft is lib/silccore/silcpacket.h.
2097 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2098 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2099 is used as part of backup router protocol when the primary
2100 router of the cell is back online and wishes to resume
2101 the position as primary router.
2103 * Redefined the MAC generation keys in the protocol. The
2104 same key is not used anymore in both direction. Both
2105 direction will now use different keys for sending and
2106 receiving. This fixes a potential security flaw. This
2107 change causes incompatibilities in the protocol.
2109 * Redefined also the MAC computation from the packet.
2110 An packet sequence number is now added to the MAC
2111 computation. This prevents possible replay attacks against
2112 the protocol. This change too causes incompatibilities
2115 Added `sequence' field to the SilcPacketContext to hold
2116 the current sequence number for the packet.
2118 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Added `created' field to the SilcIDListData in the file
2121 silcd/idlist.h to indicate the time when the entry was
2124 * Added `created' field to the SilcChannelEntry too. Affected
2125 file silcd/idlist.h.
2127 * Added `creation_time' aguments to all the announcement functions
2128 in the server. If it is provided then only the entries that
2129 was created after the provided time frame are actually
2130 announced. Affected file silcd/server.[ch].
2132 * The protocol says that the Channel ID's IP address must be
2133 based on the router's IP address. Added check for this in
2134 the silc_server_new_channel when processing incoming New Channel
2135 Payload. Affected file silcd/packet_receive.c.
2137 * Print out the correct version with --version in SILC client.
2138 Affected file irssi/src/silc/core/silc-core.c.
2140 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2142 * Fixed WHOWAS command to check for completnes of the client
2143 entry always, not just when the command is coming from client.
2144 Affected file silcd/command.c.
2146 * Added new function silc_server_packet_queue_purge to purge the
2147 outgoing data queue to the network. After the function returns
2148 it is guaranteed that the outgoing packet queue is empty.
2149 Affected file silcd/packet_send.[ch].
2151 * Purge the outgoing packet queue in the rekey protocol's final
2152 callback to assure that all rekey packets go to the network
2153 before quitting the protocol. Affected file silcd/server.c.
2155 * Added silc_client_packet_queue_parse as similar function as
2156 in server to the client library. The affected file is
2157 lib/silcclient/client.c.
2159 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Splitted silcd/server.c and created silcd/server_util.[ch]
2162 for utility functions.
2164 * Added new socket flag SILC_SF_DISABLED to indicate that the
2165 connection is open but nothing can be sent to or received from
2166 the connection. Affected file lib/silcutil/silsockconn.[ch].
2167 The checking for disabled socket is checked in the low level
2168 silc_socket_write and silc_socket_read functions.
2170 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2172 * Allow only nicknames and channel names that fits into the
2173 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2175 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2177 * When processing JOIN command reply in server check that if
2178 the channel exists in our global list we'll move it the local
2179 list. Affected file silcd/command_reply.c.
2181 * Fixed the check whether client is joined on the channel already
2182 in JOIN command. Affected file lib/silcclient/command.c.
2184 * Fixed the JOIN command reply to check whether the channel
2185 already exists. Affected file lib/silcclient/command_reply.c.
2187 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Added silc_ske_status_string to map the SKE error numbers
2190 to readable strings. The affected files are
2191 lib/silcske/silcske[_status].[ch].
2193 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Do not show the private channels on the WHOIS channel list
2196 as it is not allowed by the protocol. The affected file is
2199 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2201 * Assure that the packet length digged from the actual packet
2202 is something sensible in the silc_packet_decrypt_rest_special
2203 in lib/silccrypt/silcpacket.c.
2205 * Free and NULL the allocated pointer in silc_hmac_alloc if
2206 the HMAC allocation fails. The affected file is
2207 lib/silccrypt/silchmac.c.
2209 * Print the selected security properties to the log files in
2210 the server. Affected file silcd/protocol.c.
2212 * Add SKE's reference counter even if calling the completion
2213 callback manually. Otherwise it goes negative, although it
2214 does not cause any problems. The affected file is
2215 lib/silcske/silcske.c.
2217 * Remove the client entry with short timeout after giving the
2218 KILL command. Affected file lib/silcclient/command.c.
2220 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2221 case all found clients are already disconnected (WHOWAS would
2222 found them) in the server. Affected file silcd/command.c.
2224 * Update the last_receive (time of last data received) to be
2225 updated only when received private or channel message so that
2226 the idle time showed in WHOIS makes more sense.
2228 * Added boolean field `valid' in to the SilcClientEntry in the
2229 client library to indicate whether the entry is valid or not.
2230 This fixes the nickname change bug on channel when changing
2231 the nickname to be same than the old (like nick to Nick) the
2232 nickname formatter doesn't set the new nick anymore to Nick@host.
2233 Affected file lib/silcclient/idlist.[ch].
2235 * Now actually fixed the nickname changing on disconnection.
2236 Added new function silc_change_nick to the Irssi SILC Client.
2237 Affected file irssi/src/silc/core/client_ops.c,
2238 irssi/src/silc/core/silc-nicklist.[ch].
2240 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Check that the public key exists in the GETKEY command before
2243 trying to encode it. Affected file silcd/command.c.
2245 * Print some notifications on received public keys with GETKEY
2246 command in the Irssi SILC Client. Affected files are
2247 irssi/src/fe-common/silc/module-formats.[ch],
2248 irssi/src/silc/core/client_ops.c.
2250 * Use IDENTIFY command to resolve the server information in the
2251 GETKEY command instead of INFO command. Affected file
2252 lib/silcclient/command.c.
2254 * All command reply functions in the client library now calls
2255 the pending command reply callbacks even if an error has
2256 occurred. The server has done this a long time and now it was
2257 time to move the client library to this as well. Now all
2258 errors can be delivered back to the pending command reply
2259 callbacks if necessary. Affected files are
2260 lib/silcclient/command[_reply].[ch].
2262 * Change the nickname on disconnection back to the username
2263 because in reconnect the server will enforce it to it anyway.
2264 Affected file irssi/src/silc/core/silc-servers.c.
2266 * Fixed a config file parsing bug in the Irssi SILC client.
2267 Affected file irssi/src/silc/core/clientconfig.c.
2269 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * When printing the channel mode on JOIN, verify that the
2272 channel key and channel's HMAC are valid. Affected file
2273 irssi/src/silc/core/client_ops.c.
2275 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2278 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2279 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2281 * Removed channel key rekey task deleting from the function
2282 silc_server_save_channel_key. Affected file silcd/server.c.
2283 Added explicit timeout task context instead that is used to
2284 delete the task if we are registering a new task before the
2285 new task has elapsed.
2287 * When channel key rekey occurs the client library now saves
2288 the old channel key for a short period of time (10 seconds) and
2289 is able to use it in case some is still sending channel
2290 messages encrypted with the old key after the rekey. Affected
2291 file lib/silcclient/[idlist.h|client_channel.c].
2293 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2295 * Added check to the silc_server_new_id_real to not accept
2296 new ID if it is the sender's own ID. Affected file is
2297 silcd/packet_receive.c.
2299 * Assure that we do not announce ourself or the one we've
2300 sending our announcements when we're router and are announcing
2301 servers to our primary router. Affected file silcd/server.c.
2303 * Fixed silc_server_command_identify_check_client to assemble
2304 correct WHOIS packet. It send corrupted WHOIS packet and
2305 caused problem with router to router connections. Affected
2306 file silcd/command.c.
2308 Fixed also silc_server_command_whois_check the same way
2309 as for the IDENTIFY command.
2311 * Added new SilcIDListStatus to the server in the SilcIDListData
2312 structure. The status now includes the current status of
2313 the entry (like registered, resolved etc.). Affected file
2314 silcd/idlist.[ch]. Defined a bunch of different status types
2315 as well. This replaced the old boolean registered field as well.
2317 Added resolve_cmd_ident field to the SilcClientEntry structure
2318 too so that if the entry is for example being resolved so
2319 another command may attach to the same pending command reply
2320 without requiring to resolve the same entry again. This concept
2321 should optimize the WHOIS and the IDENTIFY resolving under
2322 heavy load by taking away unnecessary resolving for entries
2323 that are being resolved already.
2325 Added support for adding multiple pending commands for one
2326 command idenfier. Affected file silcd/command[_reply].[ch].
2328 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2329 before deleting the data. Otherwise the hash table will have
2330 freed data in comparison functions. Affected file is
2331 silcd/command_reply.c.
2333 * Fixed silc_idlist_replace_client_id to add the new entry to
2334 the cache with NULL nickname. Otherwise there will be invalid
2335 memory as the nickname after the nickname is freed. Affected
2336 file silcd/packet_receive.c.
2338 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2339 saved into wrong slots because the previous number of entries
2340 was not taken into account. Affected file silcd/idlist.c.
2341 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2343 * If we are router and we receive JOIN notify to a channel that
2344 does not have any users then notified client is marked as the
2345 channel founder, as it is it. The affected file is
2346 silcd/packet_receive.c
2348 * Added to the extended hash table API's table_del_*ext functions
2349 the destructor as argument too, so that the caller can decide
2350 which destructor to use or whether to use destructor at all.
2351 Affected file lib/silcutil/silchashtable.[ch].
2353 * Fixed ID Cache purging. It actually deleted the entries from
2354 the hash table after the data was freed. The hash table ended
2355 up comparing freed memory. The affected file is
2356 lib/silccore/silcidcache.c.
2358 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Fixed Irssi SILC client's KILL command's HELP syntax.
2362 * The USERS command now resolves the detailed user information
2363 if the userinfo field is missing. Affected file is
2364 lib/silcclient/command_reply.c.
2366 * Do not print error in silc_file_read if the read file does
2367 not exist. Just silently return NULL. Affected file is
2368 lib/silcutil/silcutil.c.
2370 * Fixed the silc_log_output to not wine about NULL filename
2371 and to not create some bogus " " filename. Affected file is
2372 lib/silcutil/silclog.c.
2374 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2376 * Fixed various printing bugs on the user interface in the
2377 Irssi SILC Client. Minor changes that were forgotten from
2380 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * Fixed the configure.in.pre and the compilation and distribution
2383 environment to support the new autoconf 2.52. That version is
2384 now required to compile the CVS trunk.
2386 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2388 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2389 to generally parse user@fqdn format strings. Affected file
2390 lib/silcutil/silcutil.c.
2392 * Added nickname_format and nickname_force_format fields to the
2393 SilcClientParams structure. The first one defines the format
2394 for the nicknames that the library will enforce if the receives
2395 multiple same nicknames. The second one is boolean value and
2396 can be used to force the library to always enforce the format
2397 to the nicknames regardles whether there are multiple nicknames
2398 or not. This configurable formatting was employed to flexibly
2399 support accessing multiple nicknames from the user interface.
2400 The userinterface can now set the nicknames to what ever format
2401 they prefer. Affected file lib/silcclient/silcapi.h.
2403 Added function silc_client_nickname_format to the file
2404 lib/silcclient/idlist.c. It performs the nickname formatting.
2406 Added new field `hostname´ to the SilcClientEntry context.
2407 It holds the hostname of the client. Affected file is
2408 lib/silcclient/idlist.h.
2410 * Irssi SILC Client sets the nicknames in nick@hostn format.
2411 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2412 irssi/src/silc/core/silc-core.c.
2414 The WHOIS printing now also shows both the real nickname and
2415 the formatted nickname so that user knows how to access the
2416 user if there are multiple same nicknames cached. Affected
2417 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2418 printing formatting too to take the hostname now as a separate
2419 argument. The Affected file is
2420 irssi/src/fe-common/silc/modules-formats.[ch].
2422 * Changed the silc_client_get_clients_local to accept the formatted
2423 nickname as argument. It accepts the real nickname too but the
2424 formatted nickname can be used to find the true entry from
2425 multiple entries. Affected file lib/silcclient/silcapi.h and
2426 lib/silcclient/idlist.c.
2428 * Added nickname_format_parse field to the SilcClientParams.
2429 It is a callback function provided by the application to parse
2430 the nickname out of the formatted nickname string. The library
2431 calls it to get the nickname from the formatted string. Since
2432 the application generally knows better the format of the nickname
2433 string it parses it instead of the library, even though library
2434 encodes the formatted string. If the callback function is not
2435 provided then the library will use the string as is. The
2436 affected file is lib/silcclient/silcapi.h.
2438 * All the nickname strings passed to the client library in
2439 commands are now expected to be formatted nickname strings.
2440 If the command does not support the formatted nickname string
2441 it will assume that the sent string is the actual nickname.
2442 Affected file lib/silcclient/command.c.
2444 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Added public key authentication support to OPER and SILCOPER
2447 commands in the client library. Affected file is
2448 lib/silcclient/command.c.
2450 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Changed the get_auth_methdod client operation to be asynchronous.
2453 It can be async if the application resolves the authentication
2454 method from the server during the negotiation. Added new
2455 SilcGetAuthMeth completion callback that the application will
2456 call after resolving the authentication method.
2458 Added function silc_client_request_authentication_method that
2459 the application can use to resolve the authentication method
2460 from the server. Added also SilcConnectionAuthRequest callback
2461 that the library will call after the server has replied. The
2462 application can call this function if it does not know the
2463 current authentication method.
2465 Affected files are lib/silcclient/client.c and
2466 lib/silcclient/silcapi.h.
2468 * The Irssi SILC client now automatically resolves the authentication
2469 method incase any configuration information is not present (and
2470 currently there never is). The affected file is
2471 irssi/src/silc/core/client_ops.c.
2473 * Fixed public key authentication from the client library.
2474 Affected file lib/silcclient/protocol.c. Changed also the
2475 protocol specification about the public key authentication in
2476 the connection authentication protocol. The actual data to be
2477 signed is now computed with a hash function before signing.
2479 * Fixed the public key authentication from the server as well.
2480 Affected file silcd/protocol.c.
2482 * Removed the mlock()'s from the memory allocation routines.
2483 Affected file lib/silcutil/silcmemory.c. The ./configure does
2484 not check anymore for the mlock(). Affected file is
2487 * Fixed USERS command in server to allow the execution of the
2488 command for private and secret channels if the client sending
2489 the command is on the channel. Affected file silcd/command.c.
2491 * Fixed silc_client_get_clients_local to return the clients
2492 count correctly. It could return wrong value. Affected file
2493 lib/silcclient/idlist.c.
2495 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2498 types. The assembler optimizations seemed not to like 64-bit
2499 data types. The assmebler optimizations thus are now enabled
2500 also for BSD systems as opposed to only enable them for Linux.
2502 * Do not check for threads at all on BSD systems. Affected
2503 file configure.in.pre.
2505 * Removed -n and -h options from the Irssi SILC Client since
2506 they are not used in silc.
2508 * Fixed the prime generation to assure that the first digit
2509 of the generated random number is not zero since our conversion
2510 routines does not like number strings that starts with zero
2511 digit. If zero digit is seen the random number is regenerated.
2512 This caused some corrupted RSA keys when the zero first digit
2513 was met. Affected file lib/silcmath/silcprimegen.c.
2515 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Fixed WIN32 configuration in the ./configure script.
2518 Fixed to include xti.h on environments that has it.
2519 Patches by Carsten Ilchmann and andrew.
2521 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2523 * Changed the silc_id_create_client_id to be collision
2524 resistant. It is now assured that there cannot be created
2525 two same client ID's. I suspect that some weird bugs in
2526 the server were actually caused by duplicate Client IDs.
2527 Affected file silcd/serverid.[ch]. A router receiving
2528 new ID now also assures and informs the sending server
2529 if the ID caused collision.
2531 * Changed the silc_id_create_channel_id to also assure that
2532 there are no collisions.
2534 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Statement about ignoring the Mutual Authentication flag when
2537 performing rekey with PFS was a bit misleading. It is ignored
2538 if it was set in the initial negotiation, it cannot be even
2539 set in the rekey. Fixed in the ke-auth draft. Started the
2540 new versions of the protocol drafts in the doc/.
2542 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Fixed a bug in silc_client_command_identify_save when saving
2545 new channel information. The channel name was no duplicated
2546 and caused crash on exit. Affected file is
2547 lib/silcclient/command_reply.c.
2549 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * Fixed the getkey command handling in the server. Send just
2552 empty OK reply to the sender if the key could not be fetched
2553 (but everything else was ok, like the key just was not available).
2554 Changed the public key parameter to optional in the protocol
2555 specs so that empty OK reply can be sent. Affected file
2558 Added a message to Irssi SILC client to tell to user if the
2559 server did not return a public key.
2561 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2563 * Fixed a channel key regeneration bug. It registered new
2564 timeout tasks exponentially until all system resources were
2565 used. Affected file silcd/server.c.
2567 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2569 * Added the SILC Document generator to the scripts/silcdoc.
2570 It can be used to generate the Toolkit Reference Manual out
2571 of the source tree. Internally it will also use the RoboDoc
2572 generator now imported in util/robodoc.
2574 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Added couple of return's in rekey protocol if error orccurred
2577 during the protocol. The execution must be terminated.
2578 Affected file silcd/protocol.c. Also, terminate the protocol
2579 always with timeout.
2581 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2583 * The client's Client ID was created initally from the wrong
2584 nickname (it could have been in format nick@host) in the
2585 silc_server_new_client. Affected file silcd/packet_receive.c
2587 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2589 * Added some SILC_LOG_ERROR's to various error conditions
2590 if client could not be added to ID cache. Affected files
2591 silcd/packet_receive.c and silcd/server.c.
2593 * When client's sock->user_data is freed, NULL also the
2594 client->router and client->connection pointers. Added check
2595 for these pointers being NULL to various places around the
2596 code. Affected file silcd/server.c.
2598 * Added client->data.registered == TRUE checks to various
2599 places around the code to assure that unregistered client's
2600 are not handled when it is not allowed. Affected file
2603 * Added `bool registered' fields to all
2604 silc_idlist_[server|client]_get_* routines to indicate whether
2605 the fetched client needs to be registered or not. Affected
2606 file silcd/idlist.[ch].
2608 * Add your own entry as registered to the ID cache in the
2609 server. Affected file server.c.
2611 * Fixed a bug in silc_server_new_server. The SilcServer was
2612 set as the new server's context instead of SilcServerEntry.
2613 This naturally caused some weird bugs.
2615 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Do not delete the channel rekey task when adding it
2618 for in silc_server_create_channel_key.
2620 * Changed the silc_server_create_channel_key to return
2621 TRUE or FALSE to indicate the success of the channel key
2624 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2626 * Fixed MSVC++ project files and added missing files to
2627 Makefiles under win32/.
2629 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2631 * Do not add TCP_NODELAY flag if the operating system
2632 does not have it defined. Affected files are
2633 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2635 * Fixed buffer overflow from Irssi SILC Client. Affected
2636 file irssi/src/fe-common/core/themes.c.
2638 * Fixed double free in client library in the file
2639 lib/silcclient/client.c when disconnecting from server.
2641 * Applied double free patch from cras to Irssi SILC client.
2642 Affected files irssi/src/core/[modules/expandos].c
2644 * Fixed the disconnection handling to Irssi SILC Client.
2645 The application must call silc_client_close_connection
2646 in ops->connect client operation in case of failure of
2647 the connection. Affected file is
2648 irssi/src/silc/core/client_ops.c.
2650 * Do not set sock->protocol to NULL in the function
2651 silc_client_close_connection after executing the protocol's
2652 final callback since the sock might not be valid anymore.
2653 Affected file lib/silcclient/client.c.
2655 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2657 * Do not enable SILC_THREADS if the linking with libpthread
2658 did not happen. Affected file configure.in.pre.
2660 * Added notion to protocol specification that server must
2661 verify the sent authentication payload with CMODE when
2662 setting the channel founder key. Implemented it to the
2663 server. Affected file silcd/command.c.
2665 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2667 * Added _EXTRA_DIST SILC distribution variable to the
2668 distributions file. It is used to conditionally add extra
2669 files or directories to the specific distribution. Affected
2670 files ./prepare, Makefile.am.pre and distributions.
2672 Removed the `_' from the start of the distribution names.
2675 * Added README.WIN32 for instructions to compile the Toolkit
2678 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2680 * Fixed a double free in disconnection in the server. Affected
2681 file is silcd/server.c.
2683 * Fixed the lib/silcske/groups.c to work now also with GMP
2684 MP library. The string conversion did not work when using
2685 specific base and the base is indicated in the string as well.
2687 * Created win32/ directory which now includes MSVC++ specific
2688 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2689 It will appear only in the toolkit distribution
2691 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2693 * Changed the key material distribution function in case when
2694 the hash output is too short. The data is now concatenated
2695 a bit differently than it used to. Made the change to the
2696 SKE protocol specification.
2698 * Added better GMP detection to configure.in.pre. A patch
2701 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2703 * Fixed a minor bug in SKE that might cause some problem on
2704 some platforms. Affected file lib/silcske/silcske.c.
2706 * Added the cookie checking for initiator in the SKE. It checks
2707 that the responder returns the sent cookie unmodified. The
2708 affected file is lib/silcske/silcske.c. Added new SKE
2709 error type INVALID_COOKIE that can be sent during the
2710 negotiation. Fixed some memory leaks as well.
2712 * Added the "invalid cookie" error message to Irssi SILC client's
2715 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2717 * Added `task_max' field to the SilcClientParams to indicate
2718 the maximum tasks the scheduler can handle. If set to zero,
2719 default values are used. Affected file lib/silcclient/silcapi.h.
2721 * Fixed memory leaks in silc_client_close_connection. Affected
2722 file lib/silcclient/client.c.
2724 * Added silc_client_del_client_entry to client library to free
2725 all memory of given client entry. Affected file is
2726 lib/silcclient/idlist.[ch].
2728 * Added new functions silc_client_del_channel and
2729 silc_client_del_server to delete channel and server entries.
2730 Affected file lib/silcclient/[silcapi.h/idlist.c].
2732 * Removed silc_client_del_client_by_id from silcapi.h.
2734 * Fixed the INFO command to return the server's own info
2735 correctly when querying by Server ID. Affected file is
2738 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2740 * Removed the non-blocking settings in WIN32 code in the
2741 silc_sock_[read/write] and added SleepEx instead. Affected
2742 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2743 of input data is now checked with FIONREAD and ioctlsocket.
2745 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2747 * Call silc_schedule_task_del_by_context in the
2748 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2749 Affected file lib/silccore/silcprotocol.c.
2751 * Call silc_protocol_cancel for active protocols in the
2752 silc_server_close_connection if the funtion
2753 silc_server_free_sock_user_data has not been called.
2754 Affected file silcd/server.c.
2756 * Generic tasks cannot be deleted using the del_by_fd
2757 task deleting function since generic tasks does not match
2758 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2760 * Added a notion to SILCOPER help file that the SILCOPER works
2761 only on router server, not on normal server.
2763 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * Added for WIN32 support for the new scheduler as well.
2766 Affected file lib/silcutil/win32/silcwin32schedule.c.
2768 * Fixed the SHA1 implementation to work on various platforms.
2770 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2772 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2773 API. It is part of the scheduler now. Everything else is
2774 as previously but some functions has changed their names.
2775 Checkout the lib/silcutil/silcschedule.h for the interface.
2776 Updated all applications to use the new interface. Affected
2777 files are lib/silcutil/silcschedule.[ch].
2779 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2781 * Found a bug in the SKE implementation. The HASH value,
2782 specified by the protocol, was not computed correctly. The
2783 public key of the responder was not added to the computation
2784 even though it is mandatory. Affected file lib/silcske/silcske.c.
2785 This unfortunately causes incompatibilities with older
2786 clients and servers.
2788 * Added WIN32 specific network init and uninit functions:
2789 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2790 the Winsock2. Affected file lib/silcutil/silcnet.h and
2791 lib/silcutil/win32/silcwin32net.c.
2793 * Set the socket always to nonblocking mode on WIN32 after
2794 reading data or writing data. Affected file is
2795 lib/silcutil/win32/silcwin32sockconn.c.
2797 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * Fixed various compilation problems under WIN32. Affected
2800 files lib/silcutil/win32/silcwin32thread.c and
2801 lib/silcutil/win32/silcwin32schedule.c.
2803 * Removed all _internal.h #includes from public header
2804 files. Internal headers must never be included from
2807 Removed also the lib/silcske/payload_internal.h file.
2809 * All include files that may be needed (public and some others
2810 included by the public headers) by application developers are
2811 now copied to the ./includes directory. It does not copy any
2812 internal headers. Affected file Makefile.defines.pre and all
2813 Makefile.am's under lib/ and subdirs.
2815 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2817 * Do not change the ~/.silc directory's permissions automatically.
2818 Affected file irssi/src/silc/core/clientutil.c.
2820 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2822 * Do not cancel the protocol in silc_server_close_connection
2823 it might cause recursion. Now cancelled in the function
2824 silc_server_free_sock_user_data. Affected file silcd/server.c.
2826 * Fixed the silc_server_remove_clients_by_server to regenerate
2827 the channel keys correctly finally. Added also new function
2828 silc_server_remove_clients_channels to actually do it.
2829 Affected file silcd/server.c.
2831 * Fixed the silc_server_new_channel to not crash by giving
2832 wrong router to the new channel. Affected file is
2833 silcd/packet_receive.c.
2835 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2837 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2838 which is given as argument to the silc_client_alloc now.
2839 It can be used to configure the client and set various parameters
2840 that affect the function of the client.
2842 * The USERS command in server did not check whether the channel
2843 is private or secret. Affected file silcd/command.c.
2845 * Added new argument to the USERS command in protocol specification.
2846 The USERS command now can take the channel name as argument
2847 as well. Added support for this in client and server and
2848 updated the protocol specs.
2850 * Completed the GETKEY command in client. It can be now used
2851 to fetch also servers public key not only some clients.
2852 Affected files lib/silcclient/command[_reply].c.
2854 * Added silc_client_get_server to return server entry by the
2855 server name. Affected files lib/silcclient/silcapi.h and
2858 * Redefined the IDENTIFY command in protocol specification to be
2859 more generic. It now can be used to query information about
2860 any entity in the SILC Network, including clients, servers and
2861 channels. The query may be based either the entity's name
2862 or the ID. Added support for this in both client and server.
2864 Affected files silcd/command.c and lib/silcclient/command.c
2865 and command_reply.c.
2867 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2868 the _from_client and _from_server functions. Affected file
2871 * Added silc_client_get_channel_by_id_resolve to the file
2872 lib/silcclient/silcapi.h to resolve channel information by
2873 its ID. Added also silc_client_get_channel_by_id that
2874 does not resolve it from the server.
2876 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2878 * Added SilcServerEntry context into the client library
2879 to represent one server. The INFO command now allocates
2880 these to save the resolved server info. For now on the
2881 client library will also keep information about servers,
2882 connected and resolved with INFO.
2884 The INFO command now allocates the SilcServerEntry context
2885 and saves the server info there. The COMMAND_REPLY in
2886 the INFO now returns the parameters to application in
2887 same order as defined in the protocol specification.
2889 The entries are cached in the client->server_cache.
2891 * The INFO command is now issued after received the Client ID
2892 from the server. Affected file lib/silcclient/client.c.
2894 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2895 to the application as the mode changer might be server.
2896 It is guaranteed that NULL is not returned anymore to the
2897 application. Affected file lib/silcclient/client_notify.c.
2899 The ID Type is now also passed to the application so that
2900 it can check whether the returned entry is SilcClientEntry
2903 Added new function silc_client_get_server_by_id to return
2904 the server entry by ID. Affected files are the
2905 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2907 * Do not create the channel in the Irssi SILC Client when issuing
2908 the JOIN command but when received the sucessful JOIN command
2909 reply. Otherwise the channel might get created even though we
2910 could not join it. The Affected file is
2911 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2913 * Fixed a channel joining bug in router. The router must also
2914 check the channel modes, invite and ban lists etc. when serving
2915 the JOIN command sent by normal server. Affected file is
2916 silcd/command.c. The router now resolves the client's
2917 information from the server who sent the JOIN command if it
2918 does not know it, and processes the JOIN command only after
2921 * Changed the SilcCommandCb to take new argument; void *context2.
2922 Affected file lib/silccore/silccommand.h
2924 The second argument in the command callbacks in the server now
2925 includes the SilcServerCommandReplyContext if the command was
2926 called as pending command callback from the command reply.
2927 Otherwise it is NULL. When called as pending the status of the
2928 command reply will be checked and if it was erronous the
2929 error will be sent to the original sender of the command.
2930 This way the client always receives the error messages even
2931 though the server was actually the one who received the error
2932 when it resent the command to router, for example. Affected
2933 files silcd/command[_reply].[ch].
2935 * Fixed sending WHOWAS command's error message to client if
2936 the requested client could not be found. It was missing.
2939 * Changed the CMODE and CUMODE commands reply arguments in the
2940 protocol specification. The Channel ID is now sent in both
2941 of the commands to identify the channel. Implemented this
2942 new feature to the client and server. Affected files
2943 lib/silcclient/command_reply.c and silcd/command.c.
2945 * Made better checks for invite and ban lists in the JOIN
2946 command in server. Affected file silcd/command.c.
2948 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * The server now performs the incoming host IP/DNS lookup
2951 using the silc_socket_host_lookup and thus does not block
2952 the server anymore. Affected file silcd/server.c.
2954 * Completed the multi-thread support for SILC Scheduler in
2955 the lib/silcutil/silcschedule.c.
2957 * Fixed the configure.in.pre to detect the pthread correctly
2960 * Fixed a deadlock in silc_task_queue_wakeup in the file
2961 lib/silcutil/silctask.c.
2963 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Added new function silc_schedule_wakeup that is used in
2966 multi-threaded environment to wakeup the main thread's
2967 schduler. It needs to be used when a thread adds a new task
2968 or removes a task from task queues. After waking up, the
2969 scheduler will detect the task queue changes. If threads
2970 support is not compiled in this function has no effect.
2971 Implemented the wakeup mechanism to both Unix and WIN32
2972 systems. Affected files are lib/silcutil/silcschedule.[ch],
2973 lib/silcutil/unix/silcunixschedule.c and the
2974 lib/silcutil/win32/silcwin32schedule.c.
2976 * Added new function silc_task_queue_wakeup to wakeup the
2977 scheduler by the specified task queue. Affected file
2978 lib/silcutil/silctask.[ch].
2980 * The silc_socket_host_lookup_start now wakes up the scheduler
2981 after adding the timeout task. Affected file is
2982 lib/silcutil/silcsockconn.c.
2984 * The silc_socket_host_lookup is synchronous now if the threads
2985 support is not compiled in. However, the callback is still
2986 called asyncronously through the scheduler, anyway. Affected
2987 file lib/silcutil/silcsockconn.c.
2989 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2991 * Added new function silc_socket_host_lookup to perform
2992 asynchronous IP and FQDN lookups for the socket connection.
2993 Affected files lib/silcutil/silcsockconn.[ch].
2995 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2997 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2998 that may or may not compile the mutex support in.
3000 Changed the silc_mutex_alloc interface. It allocates the
3001 mutex now to the sent pointer and returns TRUE or FALSE.
3003 Affected file lib/silcutil/silcmutex.h.
3005 * Wrote the SILC Task Queue interface to support multi-threads.
3006 Affected file lib/silcutil/silctask.[ch].
3008 * Wrote the SILC Scheduler to support multi-threads. Affected
3009 file lib/silcutil/silcschedule.c.
3011 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3014 in lib/silcutil/win32/.
3016 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3018 * Defined SILC Mutex API and SILC Thread API and implemented
3019 them for Unix. Affected files are
3020 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3021 lib/silcutil/unix/silcunixmutex.c and
3022 lib/silcutil/unix/silcunixthread.c.
3024 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3026 * Fixed the silc_server_remove_clients_by_server's channel
3027 key re-generation. The hash table handling was incorrect
3028 and would not work with many channels. Affected file is
3031 * Fixed some memory leaks around the server code.
3033 * Rewrote the silc_server_get_users_on_channel to support IPv6
3034 based Client ID's. Affected file silcd/server.c.
3036 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3037 specification. However, a separate document must be written
3038 to define the detailed signing procedure and the payload
3039 associated with the flag. Defined the flag to the
3040 lib/silccore/silcchannel.h as well.
3042 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3044 * Changed the dynamic tables to static size tables in the
3045 lib/silccrypt/silchmac.c.
3047 * Removed GCC dependencies from the code. A patch by cras.
3049 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3051 * Do not show the error "Error receiving packet bla bla"
3052 in server if it really was not an error (-2 means that reading
3053 is pending). Affected file silcd/server.c.
3055 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Fixed a possible crash in silc_server_remove_clients_by_server
3058 in silcd/server.c. Fixed there also some memory leaks.
3060 * Fixed the silc_idlist_replace_client_id. It could replace
3061 wrong key in the hash table. Affected file silcd/idlist.c.
3063 * Do not check whether there are global users on the channel
3064 if the channel->global_users is FALSE. Affected functions
3065 silc_server_remove_from_one_channel and
3066 silc_server_remove_from_channels in silcd/server.c. Also,
3067 do not check if the removed client is local as we can be
3068 sure that global client was not removed from the channel
3069 and checking for global users is not needed.
3071 * The silc_server_remove_clients_by_server now re-generates
3072 the channel keys correctly for those channels that had
3073 clients removed from them. Affected file silcd/server.c.
3075 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3077 * Found the reason of random crashes in the server. We weren't
3078 ignoring the SIGPIPE signal (which can be sent in write())
3079 and it crashed the server. Affected file silcd/silcd.c.
3081 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3083 * Assure that sock->user_data is not NULL in the function
3084 silc_server_packet_send in silcd/packet_send.c.
3086 * Disconnect the remote connection if it could not be added
3087 to any ID lists in the server. The affected file is
3090 * Check in silc_server_packet_send[_real/dest] that the
3091 socket is not disconnecting and ignore the data if it is.
3092 Affected file silcd/packet_send.c.
3094 * Define inline to __inline on native WIN32 compilation.
3095 Affected file includes/silcwin32.h.
3097 * Added some explicit type casts for inline code since MSVC
3098 require them. Affected files lib/silcutil/silcbuffer.h,
3099 lib/trq/silcdlist.h and lib/trq/silclist.h.
3101 * Print warning in log files from now on if the packet
3102 decryption fails. Affected file silcd/server.c.
3104 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3106 * Changed the `say' client operation's interface to accept
3107 new `type' argument to indicate the type of the message sent
3108 by the library. The application may filter the library's
3109 messages according the type. The affected file is the
3110 lib/silcclient/silcapi.h.
3112 * Added two new functions to lib/silcclient/silcapi.h:
3113 silc_client_del_client and silc_client_del_client_by_id.
3114 Affected file lib/silcclient/idlist.c.
3116 * Moved the clientincludes.h from includes/ to silc/ and
3117 serverincludes.h from includes/ to silcd/.
3119 * The modes for the CMODE and CUMODE are now passed as
3120 uint32 for application with COMMAND_REPLY. The affected
3121 file is lib/silcclient/command_reply.c.
3123 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3125 * /WHOIS without arguments shows client's own information.
3126 Affected file lib/silcclient/command.c.
3128 * Changed PING to not accept any arguments. The specs
3129 says that client can ping only the connected server so
3130 requiring an argument is not needed. Affected file is
3131 lib/silcclient/command.c.
3133 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3135 * Fixed a fatal bug in private message sending and reception
3136 encryption and decryption when using private message keys.
3137 The implementation was incorrect and did not follow the
3138 specification. It causd that some of the message were
3139 lost since it did not use the sending and receiving keys
3140 as the protocol suggests. This has been fixed and will cause
3141 incompatibilities with older clients when sending private
3142 message encrypted with private message keys. Affected files
3143 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3144 and various other in Irssi SILC Client.
3146 Added `responder' boolean argument to the functions
3147 silc_client_add_private_message_key[_ske] to indicate when
3148 the key is added as responder or initiator of the key
3151 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3153 * Removed the silc_ske_check_version function and created
3154 a SilcSKECheckVersion callback. Added also a function
3155 silc_ske_set_callbacks that is now used to set all SKE
3156 callbacks. The callback functions are not given to
3157 the SKE functions anymore, but this function is used to
3160 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3162 * Added `silc_version' argument to the silc_client_alloc
3163 to define the version of the application for the library.
3164 The library will use the version string to compare it
3165 against the remote host's (usually a server) version
3166 string. Affected file lib/silcclient/silcapi.h
3168 * Added the KE protocol context to Key Agreement context
3169 in client library so that we can abort the SKE if it
3170 is in process when we get timeout. Affected file is
3171 lib/silcclient/client_keyagr.c.
3173 * Do not resolve the client ID forever if it returns in the
3174 first time that such client does not exist. This was done
3175 for example with private message. Affected file is
3176 lib/silcclient/client_prvmsg.c.
3178 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3180 * Do not add regex.h for WIN32. The affected file
3181 includes/silcincludes.h.
3183 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3184 not work yet 100%. It generates the DLL's automatically
3185 when compiling with --with-win32 under cygwin.
3187 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3189 * lib/contrib/regex.c is not compiled on WIN32.
3191 * Added silc_net_get_socket_opt function to the
3192 lib/silcutil/silcnet.h.
3194 * Added includes/silcwin32.h for WIN32 specific includes
3197 * Do not use ptime structure or any of the posix process
3198 functions on WIN32 in lib/silccrypt/silrng.c.
3200 * Added silc_gettimeofday to provide generic function
3201 for struct timeval on all platforms. Added the function
3202 to lib/silcutil/silcutil.h.
3204 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3206 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3207 library as they clearly belong there. As a plus side we
3208 can make the actual socket connection routines platform
3211 Added also new generic function silc_socket_read and
3212 silc_socket_write (that used to be silc_packet_[read/write].
3213 The implementation of these are platform specific.
3215 * Added WIN32 specific routines of silc_socket_[read/write]
3216 to lib/silcutil/win32/silcwin32sockconn.c.
3218 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3220 * Added preliminary support for native WIN32 compilation under
3221 cygwin (using the -mno-cygwin option for GCC) to the
3222 ./configure.in.pre. The --with-win32 now prepares the
3223 compilation for native WIN32.
3225 * Rewrote the SILC Scheduler interface in the file
3226 lib/silcutil/silcschedule.h. The scheduler is now context
3227 based and does not have anymore any global static scheduler.
3228 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3229 and created lib/silcutil/win32 directory for WIN32 based
3232 * Added Unix specific network routines to the
3233 lib/silcutil/unix/silcunixnet.c and the old
3234 lib/silcutil/silcnet.c includes now only generic routines.
3236 Added WIN32 specific network routines to the
3237 lib/silcutil/win32/silcwin32net.c.
3239 * Added Unix specific utility functions from the
3240 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3242 * Added WIN32 SILC Scheduler to the file
3243 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3246 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3248 * Do not handle JOIN notify in the server if the target client
3249 is not registered (idata->registered == FALSE). The affected
3250 file is silcd/packet_receive.c.
3252 * Update the nickrec->founder in event_cumode in the Irssi SILC
3253 client. Affected file irssi/src/silc/core/silc-channels.c.
3255 * Fixed the CUMODE_CHANGE notify handling in the server when
3256 server and router are announcing their clients on channels.
3257 Now the mode changes are saved and notified correctly. The
3258 affected file is /silcd/packet_receive.c.
3260 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3261 They really did not replace the cache entry in the ID Cache.
3262 Now they do that. Affected file silcd/idlist.c.
3264 * Fixed the KICK notify handling in the Irssi SILC client to
3265 update the channel records so that the kicked client does not
3266 appear to be on the channel. The affected file is
3267 irssi/src/silc/core/silc-channels.c.
3269 * Always update the conn->current_channel when executing command
3270 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3272 * Fixed the KILL notify handling in Irssi SILC client to remove
3273 the killed client on all channels.
3275 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3277 * Fixed the silc_parse_command_line to remove extra spaces
3278 from the start and end of the arguments. Affected file is
3279 lib/silcutil/silcutil.c.
3281 * Cancel and free any active protocol in the function
3282 silc_server_close_connection. Affected file silcd/server.c.
3284 * Cancel and free any active protocol in the function
3285 silc_client_close_connction. Affected file is
3286 lib/silcclient/client.c.
3288 * Do not execute the KILL command for clients that are in
3289 history (ie. they are not in the network). Affected file is
3292 * Fixed KILL notify handling, client does not crash anymore.
3293 Affected file irssi/src/silc/core/silc-channels.c.
3295 * Reduced the default packet buffer size from 2048 to 1024 in
3296 lib/silccore/silcpacket.c.
3298 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3299 counter to the SKE context that is incresed when the SKE library
3300 performs async operation outside the library. If the outside
3301 process frees the SKE context and FREED status will be set
3302 and the library will detect after the sync operation that the
3303 libary is freed. The affected files are
3304 lib/silcske/silcske[_status].[ch].
3306 * Resolve the client entry information in the function
3307 silc_client_channel_message to assure that NULL pointer is not
3308 passed as client entry to the application. */
3310 * Fixed the task timeout calculation to assure that there is
3311 never negative timeouts. The affected file is
3312 lib/silcutil/silcschedule.c.
3314 * Fixed the channel user mode notification sending in server.
3315 It was sent point-to-point to the router (or to server by router)
3316 but it needs to be destined to a channel. The routines now
3317 supports sending the channel user mode notifys to the channels
3318 when announcing clients and channels. Affected files are
3319 silcd/server.c and silcd/packet_receive.c.
3321 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3322 It did not actually replace the old channel entry in the cache.
3323 Affected file lib/silcclient/client_notify.c.
3325 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Fixed a possible crash in silc_packet_send_prepare. It now
3328 assures always that there is enough space in the buffer and
3329 at the tail area of the buffer (for MAC).
3331 Fixed the inbound buffer reallocation in silc_packet_read.
3332 It was old code and did not handle the reallocation correctly.
3335 The affected file is lib/silccore/silcpacket.c.
3337 * Fixed buffer overflow in silc_parse_nickname in the file
3338 lib/silcutil/silcutil.c.
3340 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * make install generates new server keys only if there is not
3345 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3348 Added check that if the NOREPLY is set then we will not send
3349 the away message. This avoids infinite loop of away messages
3350 if both clients are away. The affected file is
3351 lib/silcclient/client_prvmsg.c.
3353 * Fixed client crash if /NICK was given without arguments.
3354 Affected file lib/silcclient/command.c.
3356 * Server does not send the invite list in INVITE command back
3357 to the client if the list was not altered. Added this notion
3358 to the protocol spec as well. Affected file silcd/command.c.
3360 Fixed possible crash in INVITE command by checking the
3361 value of silc_server_get_client_route command.
3363 * Fixed the INVITE notify type handling. The arguments are now
3364 taken in correct order and client does not crash. The affected
3365 file is irssi/src/silc/core/silc-channels.c.
3367 Removed the "Inviting xxx to channel" message from the
3368 client library away and let the application handle it.
3369 Affected file lib/silcclient/command.c. Added that message
3370 to Irssi SILC client's message formats.
3372 * Fixed CMODE command crash in client. It now checks the
3373 amount of arguments correctly and does not crash. The affected
3374 file is lib/silcclient/command.c.
3376 * Do not create new channel automatically in silc_channels_join
3377 but check whether the channel by that name already exists.
3378 Affected file irssi/silc/core/silc-channels.c.
3380 * Do not send the SERVER_SIGNOFF to router if the disconnected
3381 entity was the router. Affected file silcd/server.c.
3383 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3384 SILC client as it was missing from there.
3386 Added the handling of the KICK notify to the Irssi SILC client
3387 as it was missing. Added "you have been kicked" message to
3388 Irssi SILC client's message modules formats.
3390 Added the handing of the KILL notify to the Irssi SILC client
3391 as it was missing. Added the kill message module formats
3394 The affected file is irssi/src/silc/core/silc-channels.c.
3396 * The router did not save the channel mode the server announced.
3397 Affected file silcd/packet_receive.c.
3399 * Fixed a possible crash in INFO command in server. If the
3400 server did not provide the server info it crashed. Affected
3401 file silcd/command.c.
3403 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Fixed the GETKEY command in the server to check also the
3406 global list. Otherwise the GETKEY would not work correctly
3407 in normal SILC server. Affected file silcd/command.c.
3409 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3411 * Fixed GETKEY crash, it crashed if the command did not succseed.
3413 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3416 is now real and not just an macro interface to GMP.
3418 Removed the entire GMP from the source tree and imported new
3419 NSS MPI library instead. Reason for removing GMP is that it is
3420 extremely large and compiles extremely slow. The NSS MPI
3421 is only a few files and compiles in less than 10 seconds.
3422 The speed is also about the same as GMP. The MPI is imported
3423 to lib/silcmath/mpi.
3425 If the system has GMP installed we will still use the GMP.
3426 If it is not then the NSS MPI will be compiled.
3428 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Merged a long nickname (127 characters long) crash bugfix from
3431 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3433 * Merged a freed memory reference bugfix from Irssi CVS tree.
3434 Affected file irssi/src/core/commands.c.
3436 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3438 * Added the server's public key sving and verification to the
3439 server when performing the SKE. This was missing and the
3440 remote server's (or router's) public key was accepted without
3441 checking whether we have it previously or trust it at all.
3442 Affected file silcd/protocol.c.
3444 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Check in the silc_server_timeout_remote if protocol is active
3447 and make sure that the protocol's final callback is called so
3448 that all memory if freed. Affected file silcd/server.c.
3450 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * silc_server_whois_send_reply crashed the server if the nickname
3453 was 127 characters long. Affected file silcd/command.c.
3455 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Added sanity check to the silc_server_new_client. If the hostname
3458 is provided inside username then check that the provided hostname
3459 really is the same as the resolved one. If the hostname was not
3460 resolved then check it from the public key. Affected file is
3461 silcd/packet_receive.c.
3463 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3464 if the server disconnected us and the connection is not valid
3465 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3467 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3468 the library to the lib/silcutil/silcutil.[ch].
3470 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * Close log file after open. Affected file
3473 lib/silcutil/silclog.c.
3475 * Check whether sock == NULL in silc_client_send_packet and return
3476 if it is. Affected file lib/silcclient/silcclient.c.
3478 * Check rec->entry == NULL in the Irssi SILC Client before
3479 sending the channel message. Affecte file is
3480 irssi/src/silc/core/silc-servers.c.
3482 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Merged a splitted window bugfix from Irssi CVS tree. The
3485 affected file is irssi/src/fe-text/textbuffer-view.c.
3487 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3488 It did not print nickname.
3490 * Improved the distributions system a bit.
3492 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3494 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3495 irssi/src/fe-text/gui-window.c.
3497 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3498 to in-active server. The affected file is
3499 irssi/src/silc/core/client_ops.c.
3501 * Resolve the client in USERS command reply if the entry does
3502 not have username resolved. The affected file is
3503 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3504 command to WHOIS command to really resolve stuff. The USERS
3505 is not used any more in any critical section so WHOIS can
3506 be used even though it might be slower than IDENTIFY.
3508 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3511 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Changed the protocol API a bit more consistent in the
3514 lib/silccore/silcprotocol.[ch].
3516 * Changed the following headers to ROBODoc format:
3518 lib/silccore/silcpayload.h
3519 lib/silccore/silcprotocol.h
3520 lib/silccore/silcsockconn.h
3522 All core library headers are now formatted.
3524 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Fixed a bug in Irssi SILC client; do not show that you are
3527 server/router operator if you really are not. Affected file is
3528 irssi/src/silc/core/client_ops.c.
3530 * Renamed silc_command_free_payload to silc_command_payload_free.
3531 Affected file lib/silccore/silccommand.h
3533 * Added silcmath.h to include the prototoypes of various routines
3534 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3537 * Changed the following headers to ROBODoc format:
3539 lib/silccore/silcchannel.h
3540 lib/silccore/silccommand.h
3541 lib/silccore/silcid.h
3542 lib/silccore/silcidcache.h
3543 lib/silccore/silcmode.h
3544 lib/silccore/silcnotify.h
3545 lib/silccore/silcpacket.h
3546 lib/silcmath/silcmath.h
3548 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3550 * Added checking to the server code not to start the server if
3551 ciphers and stuff are not configured properly. Affected files
3552 silcd/serverconfig.[h] and silcd/server.c.
3554 * Changed the layout of the header files of the public interfaces
3555 in the SILC libraries. The new layout supports ROBODoc
3556 documentation tool (and some others) so that it is easy to create
3557 a library reference manual. All the other headers and source
3558 code must still follow the CodingStyle document. Also source
3559 code must not include these ROBODoc stuffs, only the headers.
3560 Furthermore, all public interface headers must now be named
3561 by using `silc' prefix, example: silcapi.h, silccipher.h.
3562 Some files were renamed due to this. All the other headers
3563 must not be used as public interfaces. I will update the
3564 CodingStyle document later. Changed following headers, so far:
3566 lib/silcclient/silcapi.h
3567 lib/silccore/silcauth.h
3568 lib/silccore/silcprivate.h
3569 lib/silccrypt/silcdh.h
3571 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3575 * Removed silc_client_packet_send_flush from the client library
3576 as it is not needed. Affected file lib/silcclient/client.[ch].
3578 * Added printing of message of unresolved authentication method
3579 to the Irssi SILC client. Added it to the module formats.
3580 Removed the same message from the client library.
3582 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Added new distribution feature, DISTLABEL. Every distribution
3585 can define own preprocessor label that can be used in the
3586 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3587 file distributions, acconfig.h.pre and prepare.
3589 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Added Makefile.defines_int to include the actual definitions
3592 for Makefile.defines.in. Tested the new distribution system,
3593 created distributions and tested installation.
3595 * Added AWAY message printing to the Irssi SILC client. Added
3596 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3598 * Added SCONNECT command to call the SILC's CONNECT command.
3599 Cannot use CONNECT directly since Irssi uses that internally.
3600 Affected file irssi/src/silc/core/silc-servers.c.
3602 Added ACTION local command. It is same as ME command but takes
3603 the channel as mandatory argument.
3605 Rewrote some of the Irssi's help files to suite for SILC
3608 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Added Makefile.defines[.in] that should for now on be included
3611 in all Makefile.am file in the source tree. That file includes
3612 all common compilation definitions for SILC source tree.
3614 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3616 * Minor changes to the ./prepare script to change the package
3617 name according the distribution name to the configure.in.
3619 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Created new distribution system. Added file `distributions'
3622 that defines all the distributions that can be created out of
3623 the SILC source tree. The ./prepare script now reads that
3624 file to determine how to prepare the distributions. The
3625 first argument to the ./prepare is the name of the distribution
3626 and second is the version of the distribution. If given
3627 without arguments it creates the default (toolkit) distribution
3628 with the default version (defined in ./prepare).
3630 All Makefile.am files that are subject to the distributions
3631 are now named as Makefile.am.pre. These are ./Makefile.am
3632 and lib/Makefile.am. Others may be changed later.
3634 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3636 * Added invite list, ban list, some key management and connection
3637 error message printing to module formats in the Irssi SILC client.
3639 * Added new silc_client_set_away_message to set the away message
3640 that is back to the person who sent private message. The
3641 affected file lib/silcclient/silcapi.h and the
3642 lib/silcclient/client_prvmsg.c.
3644 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Fixed the private message sending in the Irssi SILC client,
3647 added local command KEY to the Irssi SILC client.
3649 Added key management and key agreement message formats to the
3650 irssi/src/fe-common/silc/module-formats.[ch].
3652 Added USERS (alias WHO) printing, server/router operator
3653 indication and LIST command printing to the module formats.
3655 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Fixed channel joining notify handling, cumode notify handling
3658 from Irssi SILC client.
3660 * Added SILC specific module-formats to the Irssi SILC client so
3661 that SILC specific message hilighting, colors etc is possible.
3662 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3664 Added channel mode, channel user mode, actions, notices,
3665 whois and whowas printing to the the module-formats.c.
3667 * Fixed a bug in channel deletion in the server. The channel
3668 is not left to the cache even if the channel founder auth mode
3669 is set when there are no users anymore on the channel. Affected
3670 file silcd/server.c.
3672 * The silc_net_localhost now resolves the entire hostname including
3673 the domain name. Affected file lib/silcutil/silcnet.c.
3675 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Changed the ask_passphrase client operation to be ascynchronous.
3678 It has now a completion callback and a context that the
3679 application must call after it has got the passphrase from
3680 the user. Affected files lib/silcclient/silcapi.h,
3681 lib/silcclient/protocol.c, lib/silcclient/command.c and
3684 Added SilcAskPassphrase callback that the application calls
3685 to deliver the passphrase to the library.
3687 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3688 The public key verification and especially a certificate
3689 verification is asynchronous procedure.
3691 Added new SILC_SKE_STATUS_PENDING status to indicate the
3692 request is pending and a callback will be called to finalize
3695 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3696 indicate that remote end did not send its public key (or
3697 certificate), even though we require it. Added check for this
3698 condition in the SKE. This was a security bug, now fixed.
3700 Defined new SilcSKEVerifyCbCompletion callback that is called
3701 when the verification process is completed.
3703 The affected files lib/silcske/silcske_status.h and
3704 lib/silcske/silcske.[ch].
3706 * Changed the verify_public_key client operation to be async
3707 as well. Defined SilcVerifyPublicKey callback that is used to
3708 indicate the success of the public key verification process.
3710 Changed the server and client to use the new async client
3713 * Changed the Irssi SILC client's internal scheduler to be called
3714 twice as many times as it used to be. As a result the client
3715 should be a bit faster now. Affected file is
3716 irssi/src/silc/core/silc-core.c.
3718 * Added support to Irssi SILC client of asynchronous public key
3719 verification and passphrase inquiry. Affected file is
3720 irssi/src/silc/core/silc-core.c.
3722 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3724 * Do not say "You have left channel %s" in client library.
3725 Moved it to the application. Affected files are
3726 lib/silcclient/command.c and silc/client_ops.c.
3728 * Fixed silc_client_get_clients. Command context was not
3729 duplicated and was freed memory in the callback. Affected
3730 file lib/silcclient/idlist.c.
3732 * Do not say "you are now talking..." on JOIN command in the
3733 client library. The appliation must handle it.
3735 * Do not say ".. changed topic to" in command reply in the
3736 client libary. The application must handle it.
3738 * Fixed TOPIC command sending in the client library.
3740 * Fixed a memory leak in silc_client_command_free in the file
3741 lib/silcclient/command.c.
3743 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Imported a modified version of Irssi client to the source tree.
3746 The Irssi will be used to create a new client called
3747 Irssi SILC. Imported to irssi/.
3749 Added silc_core_init_finish function to the Irssi. Affected
3750 file irssi/configure.in.
3752 A lot changes in the Makefile.ams around the irssi tree.
3754 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3756 * Do not rehash if the new size is same as the old size of the
3757 hash table, in the silc_hash_table_rehash*. The affected file
3758 lib/silcutil/silchashtable.c.
3760 * Replaced hash_table_del_by_context calls from the server
3761 (when channel->user_list and client->channels) to the
3762 hash_table_del as it is sufficient and faster.
3764 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Added silc_hash_table_list, silc_hash_table_get and the
3767 SilcHashTableList structure to provide an alternative way to
3768 traverse the hash table. The affected files are
3769 lib/silcutil/silchashtable.[ch].
3771 * Changed the server's idlist routines to use the hash table
3772 routines to optimize the code.
3774 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Replaced the client entry's `channel' list and channel entry's
3777 `user_list' list to hash tables for optimized lookup. Changed
3778 the code to use the hash table interface around the code.
3779 Affected file lib/silcd/idlist.[ch].
3781 * Added `auto_rehash' boolean argument to the function
3782 silc_hash_table_alloc to indicate whether the hash table should
3783 auto-rehash when it thinks is appropriate time. It will
3784 increase the hash table size if the there is twice as much
3785 entries in the table than the size of the table, and will
3786 decrease the size if there are twice as less entries than
3787 the size of the table.
3789 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3793 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3795 * silc_idcache_purge_by_context deletes the entry now by context
3796 as it is supposed to do. Affected file lib/silccore/idcache.c.
3798 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3799 client is not anymore valid (WHOWAS givens the info) and not
3800 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3802 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Removed the `data' and `data_len' arguments from the ID Cache
3805 interfaces and added `name' argument. ID Cache does not handle
3806 anymore the binary data only a names associated with given ID.
3808 * When hashing a Client ID with silc_hash_id the entire ID is
3809 not hashed anymore, instead only the hash of the Client ID is
3810 hashed. This way we can access the Client ID from the cache
3811 with Client ID but with the hash of the ID (which is a hash of
3812 the nickname) as well without any difference in performance.
3814 Added also silc_idcache_find_by_id_one_ext to do one on one
3815 searching when we have the actual ID. Added also function
3816 silc_hash_client_id_compare. The affected files are
3817 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3819 * When hashing the name associated with a ID it is always done
3820 in lowercase. This way we can access the cache without worrying
3821 about case-sensitivity, even though, for example nicknames are
3824 * Fixed a bug in server with channel message sending. It put
3825 wrong ID type as destination ID. The affected file
3826 silcd/packet_send.c.
3828 * silc_idcache_del_by_context now deletes from all hash tables
3829 by context. Affected file lib/silccore/idcache.c.
3831 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Changed the client library to use the new ID Cache interface.
3834 Changes around the source tree.
3836 * Added silc_hash_table_rehash_ext to rehash with specific
3837 hash function. Affected file lib/silcutil/silchashtable.[ch].
3839 * Added silc_hash_string_compare to compare two strings in the
3840 hash table. Affected file lib/silcutil/silcutil.[ch].
3842 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * Added new function silc_idcache_del_by_context into the
3845 lib/silccore/idcache.[ch].
3847 * Changed the server's ID list routines to use the new ID Cache
3848 interface. Changes around the source tree.
3850 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Added silc_hash_table_del[_by_context]_ext functions in to the
3853 lib/silcutil/silchashtable.[ch].
3855 Removed silc_hash_table_find_all* routines and added new
3856 silc_hash_table_find_foreach to replace them.
3858 Added silc_hash_table_replace_ext function as extended
3859 replacing function. Separated the simple hash table interface
3860 from the extended hash table interface in the file
3861 lib/silcutil/silchashtable.h.
3863 * Fixed minor bugs and changed it to use some of the new
3864 hash table functions in lib/silccore/idcache.c
3866 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3868 * Added new function silc_hash_table_find_all to return all keys
3869 in the hash table by the specified key. As the hash table is
3870 collision resistant it also makes it possible to have several
3871 duplicate keys in the hash table. This function may be used to
3872 find all of the keys from the hash.
3874 Added user_context arguments to the SilcHashFunction,
3875 SilcHashCompare and SilcHashDestructor to deliver user specified
3878 Added new fuctions silc_hash_table_find[_all]_ext to do
3879 extended lookup with specified hash and compare functions and
3880 specified user contexts.
3882 Added new function silc_hash_table_add_ext to add the key
3883 with specified hash function and user context.
3885 Added new function silc_hash_table_foreach to traverse all
3886 entrys in the hash table. Added SilcHashForeach callback
3889 Added new function silc_hash_table_del_by_context to delete
3890 the entry only if the context associated with the key matches.
3892 Affected files are lib/silcutil/silchashtable.[ch].
3894 * Removed silc_hash_[server/client/channel]_id and added just
3895 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3896 silc_hash_id_compare to compare two ID's using as the hash table
3897 comparison function. Added also silc_hash_data to hash
3898 binary data and silc_hash_data_compare to compare it.
3900 * Removed silc_idlist_find_client_by_hash as it is not needed
3901 anymore. Affected file silcd/idlist.[ch].
3903 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3904 to use internally the SilcHashTable. The new ID Cache is a lot
3905 faster than the old one. Some of the ID Cache interface was also
3906 rewritten and obsolete and stupid functions were removed.
3908 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Added entry_count field to the SilcHashTable to keep the number
3911 of the entries in the table. Implemented the function
3912 silc_hash_table_rehash. Added new function
3913 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3915 Fixed a minor bug in silc_hash_table_free.
3917 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3918 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3919 into the lib/silcutil/silcutil.[ch].
3921 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3923 * Implemented a collision resistant hash table into the
3924 lib/silcutil/silchashtable[ch]. See the header and the source
3925 for the SilcHashTable API.
3927 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Merged dotconf version 1.0.2 into lib/dotconf.
3931 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Do not compile anything in lib/silcsim/* if the SIM support
3934 is not enabled. The tree should now compile without problems
3937 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * Compiled the SILC under cygwin. Compiled and tested briefly
3940 without problems. More tests needed. The SIMs didn't compile
3943 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3945 * Fixed possible crash in silc_get_username in the
3946 lib/silcutil/silcutil.c.
3948 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3950 * Fixed a va_arg in silc/client_ops.c.
3952 * Oops, RC5 routines were named AES and caused some problems
3953 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3955 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Added new SilcIDIP structure into the lib/silccore/id.h and
3958 replaced the old `ip' fields from all SILC ID's to that type.
3959 This is a step towards IPv6 support.
3961 The silc_id_get_len takes now the ID as an extra argument.
3962 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3963 both IPv4 and IPv6 based ID's.
3965 The affected files are lib/silccore/id.[ch] and other files
3966 around the tree using these routines.
3968 * Removed the ID length arguments in server from various
3969 silc_server_send_notify_* routines -> they are not needed
3972 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * Fixed memory leak in silc_encode_pem_file in the file
3975 lib/silcutil/silcutil.c.
3977 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Check minor version as well in the SKE. Affected files are
3980 silcd/protocol.c and lib/silcclient/protocol.c.
3982 * Added --identifier option to the server so that an identifier
3983 can be when creating the public key for the server. Affected
3984 file is silcd/silcd.c.
3986 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3987 lib/silccrypt/silcpkcs.c.
3989 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Register default ciphers and stuff when using -C option with
3992 the server. Affected file sildc/silcd.c.
3994 * Put back the servers public key filename format, it is better
3995 than the new one. For now, the client keys are saved with the
3996 new filename format. The affected file silc/client_ops.c.
3998 * Implemented the Cipher API for the rest of the ciphers that
3999 did not implement it or implemented it the wrong way.
4001 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Register default ciphers and stuff when using the -S option
4004 in the client. Affected file silc/silc.c. Same also when
4005 creating new key pair with -C option.
4007 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Fixed the silc_verify_public_key client operation function to
4010 save the public keys differently. The fingerprint is now
4011 used as filename and not the hostname. This way also the
4012 client keys are saved uniquely and not with hostnames. The
4013 affected file is silc/client_ops.c.
4015 * Trimmed the silc_hash_fingerprint function to remove extra
4016 whitespaces from the end of the fingerprint. The affected
4017 file is lib/silccrypt/silchash.c.
4021 * Added silc_cipher_register_default function to register all
4022 default ciphers. It can be used when configuration files
4023 does not exist and the application does not want any specific
4024 ciphers in any specific order.
4026 The SilcDList is now used as silc_cipher_list dynamically
4027 allocated cipher list. Removed the static list all together
4028 and now all ciphers must be allocated to the dynamic list.
4029 The silc_cipher_alloc routine was changed to check only the
4032 All silc_cipher_* routines that used to return int returns
4035 The affected files lib/silccrypt/silccrypt.[ch].
4037 * The same thing was done to silc_hash_* as for silc_cipher_*
4038 routines. Affected files lib/silccrypt/silchash.[ch].
4040 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4041 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4042 Added also silc_pkcs_[un]register[_default] functions.
4043 Removed the data_context from the PKCS API.
4045 * Added silc_hmac_register_default function to register default
4046 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4047 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4048 to unregister all hmacs at once.
4050 * Register the default ciphers, hash functions, PKCSs and HMACs
4051 if client's configuration file does not exist. The affected
4054 * The client did not load the hash functions from the SIM
4055 modules at all. Added support for this. Affected file is
4056 silc/clientconfig.c.
4058 * When decoding public key with silc_pkcs_public_key_decode, check
4059 the supported algorithm only if PKCS are registered. Affected
4060 file lib/silccrypt/silcpkcs.c. The same was done with the
4061 silc_pkcs_private_key_decode.
4063 * Fixed the SILC List routines to keep the list always in order.
4064 It used to change the list's order when traversing the list but
4065 not it preserves the order. Affected file lib/trq/silclist.h.
4067 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Added the client library to use the SilcSocketConnection's
4070 reference counter (by silc_socket_dup) to prevent the bug that
4071 the socket object may be freed underneath async operation.
4073 * The name resolv library checking fixes in the configure.in.pre.
4076 * Created new version of the protocol drafts for future
4077 development. The -03 drafts are the ones that will be changed
4078 in the trunk now and the -02 will remain as they are.
4080 * Send list of CUMODE notifys to the router when announcing
4081 the channel users to the router. Affected file silcd/server.c.
4082 If the router receiving channel founder CUMODE for a channel
4083 that already has channel founder it will send CUMODE notify
4084 to the sender to remove the channel founder rights from the
4085 announced client. Affected file silcd/packet_receive.c.
4087 * The CUMODE notify may now use Server ID as well as the entity
4088 who changes the mode. Updated protocool specs.
4090 * Updated INSTALL and README files.
4092 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * New web pages in the http://silc.pspt.fi. The pages was
4099 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * Implemented the [DenyConnectin] config section in the server.
4102 Added silc_server_config_denied_conn to check whether incoming
4103 connection is denied. Affected file silcd/serverconfig.[ch].
4105 * Do not check the ports when checking the incoming configuration
4106 data if the port is 0, meaning any. Affected file is
4107 silcd/serverconfig.c.
4109 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Fixed buffer overflow in silc_string_compare in the file
4112 lib/silcutil/silcutil.c.
4114 * Fixed double free in silc_server_command_leave in the file
4117 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Fixed the version checking in the server. Affected file is
4122 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Fixed the configuration data fetching when accepting new
4125 connections in the server. Affected file silcd/server.c.
4127 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4129 * Added `sender_entry' argument to the function
4130 silc_server_packet_relay_to_channel so that we can check
4131 whether some destination actually belongs to the same route
4132 the sender belongs (ie, we must not resend the packet to the
4133 sender). Affected file silcd/packet_send.[ch].
4135 * Added `servername' field to the SilcClientEntry in the server
4136 to hold the name of the server where client is from. Affected
4137 file is silcd/idlist.h.
4139 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * Moved the channel message encrypting in the router betwen
4142 router connections from silc_server_channel_message to the
4143 silc_server_packet_relay_to_channel since we want to check
4144 whether we have anybody channel before encrypting anything.
4145 Affected files silcd/packet_[receive/send].c.
4147 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Fixed the [AdminConnection] server config section to support
4150 multiple entries. Affected file silcd/serverconfig.c.
4152 * Added support into the server to check the validity of the
4153 incoming connection before executing any KE or authentication
4156 * The connection configuration is now saved to the KE and
4157 connection auth protocol contexts and not fetched anymore in
4158 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4160 * The local hosts listenning address and port is also resolved
4161 now when starting the server. We want to have the socket object
4162 to include the real address and port for the listener. Added
4163 new function silc_net_check_local_by_sock into the files
4164 lib/silcutil/silcnet.[ch].
4166 * Fixed a broadcast bug in server -> do not broadcast if we
4169 * Fixed a routing bug. Do not route broadcast packets ever.
4170 Broadcast packets must be processed always and not routed since
4171 they may be destined to some other host than yourself and thus
4172 would get routed without no good reason. Affected file is
4175 * Added function silc_server_config_is_primary_route to check
4176 whether primary router connection has been configured (a router
4177 configuration that we are initiating). If there is not, we
4178 will assume that there is only two routers in the SILC network
4179 and we will use the incoming router connection as our primary
4180 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4182 * Changed the order of the broadcasting. Broadcast _after_ the
4183 packet has been processed not before. Affected file is
4186 * Fixed a [ClientConnection] parsing bug. The port was never
4187 parsed correctly thus resulting to port 0. Affected file
4188 silcd/serverconfig.c.
4190 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4191 argument and did not set the broadcast packet flag. Affected
4192 file silcd/packet_send.c. Fixed same bug in the function
4193 silc_server_send_notify as well.
4195 * If we receive NEW_ID packet for our own ID in the server, ignore
4198 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Removed the nickname from the Private Message Payload.
4203 Updated the code and the protocol specs.
4205 * Updated protocol specs for submitting to the IETF.
4207 * Tweaked the Random Number Generator a bit. Affected file
4208 lib/silccrypt/silcrng.c. Exported a new function
4209 silc_rng_[global]_add_noise which can be used to add more
4212 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Do not parse packets with different timeout when protocol
4215 is active -> may cause problem with rekey. Affected file
4218 * When server receives signoff notify it must not create
4219 new channel key if the client is on any channels since the
4220 sender of the signoff notify will create it.
4222 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * Added printing of error messages during SKE protocol from the
4225 failure packet sent by server during SKE. Affected file
4228 * Removed the client's failure_callback handling with timeout
4229 and handle it immediately when received.
4231 * The SKE library returned wrong type in SUCCESS and FAILURE
4232 packets. They must be 32 bit MSB not 16 bit MSB.
4234 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Ok, rewrote the logic of the re-key and now it seems to work.
4237 I tested it on high traffic with frequent re-keys without
4238 problems. Added hmac_receive (and renamed hmac to hmac_send)
4239 in SilcClientConnection in lib/silcclient/client.h and
4240 in SilcIDListData in silcd/idlist.h. Also, removed the
4241 SilcPacketParserContext's cipher and hmac fields as they are
4242 not needed anymore and actually caused some problems when
4243 the ciphers and hmac's changed underneath the packet parser.
4245 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * If re-key protocol is active then process the incoming packets
4248 synchronously since we must assure that icoming packets encrypted
4249 with the old key is processed before the new keys is set to
4250 use. This is true other packets than for REKEY packets.
4251 Affected file silcd/server.c. The same was done to client library
4252 as well, affected file lib/silcclient/client.c.
4254 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Fixed bug in client and server to accept the force send if
4257 the packet is send from silc_[server/client]_packet_process
4258 function. Otherwise the packets are never delivered, oops.
4260 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Disable force sending of packets when REKEY protocol is active.
4263 We must assure that no packet is sent directly when rekey is
4264 performed. All packets must be sent through packet queue.
4265 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4266 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4267 function is silc_[server/client]_packet_send_real to check
4270 * Replaced the SIM paths from example config files to
4271 /usr/local/modules. Also, make install creates now
4272 /usr/local/silc/logs directory to hold all the SILC server
4275 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4277 * Made the configure.in.pre work on Solaris. Patch by salo.
4279 * Made all ciphers compatible with non-x86 machines. Defined
4280 CBC mode macros into lib/silccrypt/ciphers_def.h.
4282 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Fixed the make install.
4286 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4288 * When MAC computation fails the silc_packet_decrypt returned 0
4289 even though it was supposed to return -1. Fixed this. The
4290 affected file is lib/silccore/silcpacket.c.
4292 * Do not replace the config files in /etc/silc (in make install)
4293 if they already exist. Affected file ./Makefile.am.
4295 * Do not send re-key packets immediately but through packet queue.
4296 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4298 * Changed silc_net_check_host_by_sock to return FALSE if the
4299 IP/DNS could not be resolved. Though, it returns the IP address
4300 now even if it could not resolve it (but returns also FALSE).
4301 Affected file lib/silcutil/silcnet.[ch].
4303 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4305 * Added silc_pkcs_decode_identifier to decode the public key's
4306 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4307 Added also silc_pkcs_free_identifier. Added also new context
4308 SilcPublicKeyIdentifier.
4310 * Added -S option to the silc client. It is used to dump the
4311 contents of the specified public key file.
4313 * Changed the PKCS api to return the public key length when
4314 setting the public key.
4316 * Fixed a fatal bug in the public and private key file loading.
4317 Affected file lib/silccrypt/silcpkcs.c.
4319 * Execute the packet parsing for client with zero (0) timeout
4320 if the protocol is active. Affected file silcd/server.c.
4322 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Made the key generation options to the silcd program. Added
4325 -C option, equivalent to client's option.
4327 * Added new [ServerKeys] config section to the server. It
4328 configures the server's public and private key.
4330 * Defined generic Public Key Payload into the protocol
4331 specification to send specific type of public keys and
4334 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4335 public key or certificate.
4337 * Implemented the GETKEY command to the server and to the
4338 client library and on user interface.
4340 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Made preliminary `make install' work.
4344 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * Added SilcServerRekey context into silcd/idlist.h.
4348 * Added the PFS support as defined in the specification to the
4349 SKE protocol. Affected files lib/silcske/*.c.
4351 * Added `ske_group' field to the SilcServerRekey context to hold
4352 the number of the SKE group that is used with PFS in re-key.
4353 Affected file silcd/idlist.h.
4355 * Added PFS re-key support to the server. Affected file is
4358 * Added silc_protocol_cancel to cancel execution of the next
4359 state of the protocol. Affected file is
4360 lib/silccore/silcprotocol.[ch].
4362 * Added the re-key support with and without PFS to the client
4363 library. Re-key is performed once in an hour, by default.
4365 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4366 Added silc_client_rekey_callback and silc_client_rekey_final.
4367 Affected files are lib/silcclient/protocol.[ch] and
4368 lib/silcclient/client.[ch].
4370 * Removed the `hmac_key' and `hmac_key_len' fields from the
4371 SilcClientConnection structure; not needed. Affected file is
4372 lib/silcclient/client.h.
4376 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Do not ask whether user wants to use the negotiated private key
4379 for private messages, just use it. Affected file is
4380 silc/local_command.c.
4382 * Added `send_enc_key' and `enc_key_len' fields to the
4383 SilcIDListData structure since they are needed in the re-key
4384 phase. Affected file is silcd/idlist.[ch].
4386 * Implemented the simple re-key protocol into the server.
4387 Affected files silcd/server.c and silcd/protocol.[ch]. The
4388 re-key will be performed once in an hour, by default.
4390 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4391 Added silc_server_rekey, silc_server_rekey_callback and
4392 silc_server_rekey_final.
4394 * Removed Tunneled flag from the protocol. Updated the code
4395 and the specifications.
4397 * Adde `pfs' field to the SilcIDListData to indicate whether
4398 the PFS is to be performed in the re-key. Affected file is
4401 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4404 int64 of at least the xintXX size. If void * is less that 4
4405 bytes uint32 * will be used. Defined bool as boolean.
4407 * Changed _ALL_ unsigned long and unsigned int to uint32,
4408 unsgined short to uint16 in the source tree.
4410 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4411 not handle clients that has entry->data.registered == FALSE.
4412 They are not in the network anymore. Affected file is
4415 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * Implemented the sending of the SERVER_SIGNOFF notify in the
4418 server. Affected file is silcd/server.c.
4420 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4421 Added also silc_notify_payload_encode_args into the
4422 lib/silccore/silcnotify.[ch].
4424 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4425 Affected file silcd/packet_receive.c.
4427 * Implemented the SERVER_SIGNOFF notify handling in the client
4428 library. Affected file lib/silcclient/client_notify.c. Also,
4429 implemnted the printing of the SERVER_SIGNOFF info to the
4430 application. Affected file silc/client_ops.c.
4432 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4433 if the deleting was successful. Affected file silcd/idlist.[ch].
4435 * Added support for public key authentication in the connection
4436 authentication protocol in the client library. Affected file
4437 lib/silcclient/protocol.c.
4439 * Changed the server's silc_idlist_get_clients_by_* interface
4440 to support already allocated array so that new entries may be
4441 added to pre-allocated array. Affected file silcd/idlist.[ch].
4442 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4443 and command replies.
4445 * All command reply functions in the server now calls the
4446 pending command callback even if error occured. This way the
4447 error will be delivered to the client as well. Affected files
4448 silcd/command.c and silcd/command_reply.c.
4450 * Fixed INFO command to return local server's info if no server
4451 was provided. Affected file lib/silcclient/command.c.
4453 * Removed RESTART command for good. Updated the code and the
4456 * Rewrote parts of the task system. It is a bit simpler now.
4457 Removed unsued task priorities. The affected files are
4458 lib/silcutil/silctask.[ch].
4460 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * Moved the USERS printing from the library to the application.
4463 Affected files lib/silcclient/command.c and silc/client_ops.c.
4465 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Added channel key re-key support. The re-key is perfomed
4470 only by the router and is done once in an hour. Added `rekey'
4471 field to the SilcChannelEntry in the server. Affected files
4472 silcd/server.c and silcd/idlist.h.
4474 * Added silc_task_unregister_by_context into the file
4475 lib/silcutil/silctask.[ch].
4477 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * Added SILC_UMODE_GONE mode to indicate when the client is not
4480 present in the SILC network. Added also support to the local
4481 command AWAY that will set this mode. Added support of showing
4482 "xxx is gone" in WHOIS command. The USERS command shows the
4483 gone status as well.
4485 * Fixed setting server and router operator privileges in the
4486 server's UMODE command. Affected file silcd/command.c.
4488 * Merged the SKE KE1 and KE2 payloads into one payload. The
4489 new KE payload is equivalent to the old KE2 payload.
4491 Cleaned up the SKE Start Payload parsing. It now uses the
4492 simple buffer unformatting to do the parsing. A lot faster
4495 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4496 to the SKE that is used to indicate whether both of the SKE
4497 parties should perform authentication. By default only the
4498 responder performs authentication. By setting this flag also
4499 the initiator must do authentication. By default it is unset
4500 since in normal SKE case, client to server connection, only
4501 the responder should do authentication. When doing SKE between
4502 two clients both should perform authentication. Updated the
4503 code and the protocol specs.
4505 * A little fix to IDENTIFY command in the server. Search the
4506 client first by hash not nickname. Affected file is
4509 * Fixed the silc_client_close_connection to support closing
4510 the client to client connections wihtout deleting too much
4511 data. Affected file lib/silcclient/client.c.
4513 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4514 are received if protocol used to be active but is not anymore
4515 the application would crash due to NULL pointer dereference.
4516 Affected files silcd/server.c and lib/silcclient/client.c.
4518 * Added `hash' field to the SilcClientConnection to include
4519 the hash function negotiated in the SKE protocol.
4521 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4522 to set the channel founder authentication data. A client can
4523 claim the founder rights later by providing the authentication
4524 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4525 This way the channel founder can regain the channel founder
4526 privileges even it is left the channel. This works only on
4527 local server and the client must be connected to the same
4528 server to be able to regain the founder rights. Updated the
4529 protocol specs accordingly.
4531 Added support to the CMODE command in the client to set the
4532 founder auth data. Read the README to see how to set it.
4534 Added support to the CUMODE command to claim the founder
4535 rights. Read the README to see how to do it.
4537 Added support for the founder authentication to the Channel
4538 Entry in the server. Affected file silcd/idlist.h.
4540 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4541 server's CMODE command. Affected file silcd/command.c.
4543 * Added the following new functions into lib/silccore/silcauth.[ch]:
4544 silc_auth_get_method and silc_auth_get_data.
4546 * The server now saves the remote hosts public key to the
4547 SilcIDListData pointer. Affected file silcd/protocol.c.
4549 * The normal server now does not remove the channel entry from
4550 the cache if the founder authentication data is set. It used
4551 to remove it if the founder was the last one on the channel on
4552 the server and left the channel. The auth data is saved and
4553 if the channel is re-joined later the old entry is used with
4554 the old auth data. Affected files silcd/command_reply.c and
4557 * Removed the `pkcs' field from the SilcIDListData structure
4558 in the server; it is not used. Affected file silcd/idlist.h.
4560 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Fixed packet processing on slow links. Partial packets were
4563 never re-processed because the incoming data buffer was cleared
4564 by the application. Application must not directly clear the
4565 sock->inbuf, the packet processing routines handle it. Fixed
4566 this in client library and in server.
4568 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Fixed the WHOIS and IDENTIFY send reply function to really
4571 check whether to send list or just one entry. Affected file
4574 * Cleaned up the LEAVE command's channel key distribution. The
4575 affected file silcd/command.c.
4577 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4578 can enforce the channel mode as well. In that case the ID
4579 includes the ID of the server. The code now enforces the
4580 mode change if the router have different mode than the server.
4582 * The notify client operation with CMODE_CHANGE notify can now
4583 return NULL client_entry pointer if the CMODE was not changed
4584 by client. Application must check for this.
4586 * Added <Server ID> argument to INFO command to support server
4587 info fetching by Server ID.
4589 * Added silc_server_announce_get_channel_users to get assembled
4590 packets of channel users of the specified channel. Affected
4591 file silcd/server.[ch].
4593 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4594 was freed underneath the ID Cache.
4596 * Re-announce clients when the server received CHANNEL_CHANGE
4597 notify from the router. Affected file silcd/packet_send.c.
4599 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4602 crashed since it did not handle the fact that there is no cipher
4603 called "3" and didn't check the error condition. Now fixed.
4605 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4606 flag. It can be used to send message requests.
4608 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Implemented the RESTART command in the client.
4612 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4613 notice type messages. Added notice printing to the user
4616 * The channel keys are not re-generated if the channel's mode
4617 is PRIVKEY, ie private key on the channel exists. Affected
4618 files silcd/server.c and silcd/command.c.
4620 * Fixed a little bug in channel message delivery when channel
4621 private keys are set in the server. Affected file is
4622 silcd/packet_send.c.
4624 * Changed the setting on channel->on_channel = TRUE from the
4625 silc_client_save_channel_key to the JOIN command reply. The
4626 key payload is not received if the private channel key is set.
4627 Affected file lib/silcclient/command_reply.c and the
4628 lib/silcclient/client_channel.c.
4630 * When the CMODE_CHANGE notify is sent and the channel private
4631 key mode is removed the channel key must be re-generated in
4632 other cells as well. Added this support for the router in the
4633 silcd/packet_receive.c.
4635 * Added new local command NOTICE to send notice message on
4636 channel. Affected file silc/local_command.[ch].
4638 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4640 * Added new local command ME to the client. It is used to send
4641 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4642 some action. Affected file silc/local_command.[ch].
4644 * Changed channel_message and private_message client operations
4645 to deliver the message flags to the application. Added also
4646 the `flags' arguments to the silc_client_send_channel_message
4647 and silc_client_send_private_message functions. Affected file
4650 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Redefined the Private Message Payload to support private message
4653 keys and to support the new private message flags. Updated
4654 the protocol specs. Flags makes it possible to have for example
4655 CTCP style messages.
4657 * Added new type SilcPrivateMessagePayload and defined an API
4658 for it in the lib/silcclient/silcprivate.[ch].
4660 * Tested private message private keys successfully. Tested the
4661 private message key set, unset and list commands with the new
4664 * Redefined the Channel Message Payload to include the channel
4665 message flags (equal with private message flags) to support
4666 for example CTCP style messages.
4668 * Defined some of the message (for channel and private message)
4669 flags. Updated the protocol specs and added the flags to the
4670 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4672 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Added SilcKeyAgreementStatus type to the key agreement routines
4675 to indicate the current status and error if one occured.
4676 The status types are defined in the lib/silcclient/silcapi.h.
4678 * Added new local command KEY that is used to set and unset private
4679 keys for channels, set and unset private keys for private messages
4680 with remote clients and to send key agreement requests and
4681 negotiate the key agreement protocol with remote client. The
4682 key agreement is supported only to negotiate private message keys,
4683 it currently cannot be used to negotiate private keys for channels,
4684 as it is not convenient for that purpose.
4686 * Fixed a minor pending callback setting bug in the function
4687 silc_client_get_client_by_id_resolve, now the function works.
4688 Affected file lib/silcclient/idlist.c.
4690 * Added function silc_net_get_local_port to get local bound
4691 port by socket. Added to lib/silcutil/silcnet.[ch].
4693 * Added `sockets' and `sockets_count' fields to the SilcClient
4694 object. They hold the sockets of the listenning sockets in
4695 the client. Listenning sockets may be for example the key
4696 agreement server. Affected file lib/silcclient/client.[ch].
4697 Added functions the silc_client_add_socket and the
4698 silc_client_del_socket. They are exported to the application
4701 * Added ~./silc/clientkeys to support other client's public keys.
4703 * Renamed verify_server_key client operation to verify_public_key
4704 and added one argument to indicate the type of the connection
4705 (server, client etc.).
4707 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Added silc_server_connection_auth_request to handle the
4710 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4711 silcd/packet_receive.[ch].
4713 * Added silc_server_send_connection_auth_request into the
4714 silcd/packet_send.c to send the connection auth request packet.
4716 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4719 * Fixed the public key authentication in responder side in the
4720 server. The `auth_data' pointer includes the SilcPublicKey
4721 not the path to the public key. Affected file silcd/protocol.c.
4723 * Implemented the public key authentication in the initiator side
4724 in the server. Affected file silcd/protocol.c.
4726 * Removed the [RedirectClient] config section from the server
4727 configuration. Is not needed and I don't want to implement it.
4729 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Cleaned up the CMODE command in the server. It now works
4732 correctly and supports all the modes defined in the protocol.
4733 Affected file is silcd/command.c.
4735 * Added `hmac_name' field to the SilcChannelEntry in the server
4736 to hold the default HMAC of the channel. It can be set when
4737 creating the channel (with JOIN command). Affected files
4740 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4741 type to indicate the change of the current cipher and hmac
4742 on the channel. Client can safely ignore the <cipher> argument
4743 (if it chooses to do so) since the CHANNEL_KEY packet will
4744 force the channel key change anyway. The <hmac> argument is
4745 important since the client is responsible of setting the new
4746 HMAC and the hmac key into use.
4748 * Fixed the CMODE command in the client library as well.
4750 * Tested CMODE command in router environment successfully.
4752 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4754 * Show the version of the remote client (or server) when connecting
4755 to the server. It is logged to the log file. Affected file
4756 is silcd/protocol.c.
4758 * Fixed the KILLED notify handling in the client library. The
4759 client must be removed from all channels when receiving the
4762 Also, do not remove the client entry when giving the KILL
4763 command but when the KILLED notify is received.
4765 * Removed silc_idlist_find_client_by_nickname from the server.
4766 Not needed anymore. Affected files silcd/idlist.[ch].
4768 * Implemented the CHANNEL_CHANGE notify type handling to the
4769 server. Affected file silcd/server.c.
4773 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Added silc_server_send_notify_invite to send the INVITE
4776 notify between routers.
4778 * Implemented the INVITE command correctly to the server.
4780 * Implemented the INVITE notify type handling in the server.
4782 * Implemented the INVITE command to the client library and on the
4785 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * Added function silc_server_get_client_resolve to find the
4788 client entry by ID from all ID lists and then resolve it
4789 (using WHOIS) if it cannot be found. Affected file is
4792 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Implemented the BAN command to the client library.
4796 * The JOIN command in the server now checks the invite list
4799 * Changed the silc_command_reply_payload_encode_va and the
4800 silc_command_payload_encode_va to support that if argument is
4801 NULL it ignores and checks the next argument. Affected file
4802 lib/silccore/silccommand.c.
4804 * Added silc_server_send_notify_ban to send the BAN notify
4805 type between routers.
4807 * Chaned the silc_notify_payload_encode to support that if
4808 argument is NULL it ignores and checks the next argument.
4809 Affected file lib/silccore/silcnotify.c.
4811 * Tested ban lists in router environment successfully.
4813 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Implemented BAN command to the server, in silcd/command.[ch].
4817 * Removed the BAN and INVITE_LIST modes from the CMODE command
4820 * Added function silc_string_match to regex match two strings.
4821 Affected files lib/silcutil/silcutil.[ch].
4823 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Redefined parts of the SilcChannelEntry in the server to support
4826 the new ban and invite lists.
4828 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4830 * Redefined the INVITE command. The same command can be used to
4831 invite individuals to the channel but also to manage the invite
4832 list of the channel (to add to and remove from the invite list).
4833 Updated the protocol specs.
4835 * Added new command SILC_COMMAND_BAN that can be used to manage
4836 the ban list of the channel. Updated the protocol specs.
4838 * Removed the channel modes: the SILC_CMODE_BAN and the
4839 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4840 in the CMODE command. The equivalent features are now available
4841 using INVITE and BAN commands. Updated the protocol specs.
4843 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4844 in the network about change in the current ban list. The notify
4845 type is not used by the client.
4847 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4848 support the invite lists.
4850 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Added new function silc_string_regexify that converts string
4853 including wildcard characters into regex string that can
4854 be used by the GNU regex library. Added into the file
4855 lib/silcutil/silcutil.[ch].
4857 Added silc_string_regex_combine to combine to regex strings
4858 into one so that they can be used as one regex string by
4859 the GNU regex library. Added into the file
4860 lib/silcutil/silcutil.[ch].
4862 Added silc_string_regex_match to match two strings. It returns
4863 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4865 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Imported GNU regex to the soruce tree into lib/contrib.
4868 Fixed some compiler warning from the regex.c.
4870 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4872 * Fixed MOTD command in the server to work in router environment.
4874 * Fixed the MOTD command in the client library to support
4875 the server argument in the command.
4877 * Added `nickname_len' argument to the silc_idlist_add_client
4878 in the server, as the `nickname' argument may be binary data
4881 * Added silc_idlist_get_channels to return all channels from
4884 * Implemented LIST command to the server. Affected file is
4887 * Implemented the LIST command to the client library and on the
4890 * Added [<user count>] argument to the LIST command reply.
4891 With private channels the user count is not shown.
4893 * Updated TODO and README.
4895 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * The client entry's data.registered must be TRUE even with
4898 global client entry on global client list. The data.registered
4899 is used to check whether the client is anymore in the network,
4900 for example with WHOWAS command so it must be valid.
4902 * Fixed the WHOWAS command in the server. It now actually works
4903 in router environment. Added function into silcd/command_reply.c
4904 silc_server_command_reply_whowas_save.
4906 * Added silc_idlist_purge function to the silcd/idlist.c
4907 to periodically purge the ID Cache.
4909 * Fixed INFO command in the server. It works now in router
4910 environment. Added <server name> argument to the INFO command
4911 reply. Updated the protocol specs.
4913 * Fixed minor bug in silc_idcache_purge to not purge if the
4914 expire value is zero.
4916 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4917 they were buggy because of the WHOWAS information.
4919 * Fixed local command MSG to handle the async resolving of
4920 the remote client properly. It used to fail the first MSG.
4921 Affected file silc/local_command.c.
4923 * Added `data_len' field to SilcIDCache context.
4925 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4927 * Update TODO. Todo in commands in the server.
4929 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4932 used by routers as broadcast packet to inform other routers
4933 about the changed user mode.
4935 Implemented the notify handling in the server. Affected file is
4936 silcd/packet_receive.c. Added the function
4937 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4939 * Added new generic Channel Payload and deprecated the New Channel
4940 Payload. The New Channel Payload is now the generic Channel
4943 * Added new argument `mode' to the silc_server_send_new_channel
4944 as it is required in the Channel Payload now.
4946 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4947 and created a new and real SilChannelPayload to represent the
4948 new generic Channel Payload. Implemented the encode/decode
4949 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4951 * Added silc_server_get_client_channel_list to return the list
4952 of channels the client has joined for WHOIS command reply.
4953 Affected file silcd/server.[ch].
4955 * Implemented the channel list sending in the WHOIS command reply
4956 in server and in the client.
4958 Implemented the channel list displaying on the user interface
4959 as well. Affected file silc/client_ops.c.
4961 * Added silc_channel_payload_parse_list to parse list of Channel
4962 Payloads. It returns SilcDList list of SilcChannelPayloads.
4963 Client for example can use this function to parse the list of
4964 channels it receives in the WHOIS command reply. The caller
4965 must free the list by calling silc_channel_payload_list_free.
4966 Affected files lib/silccore/silcchannel.[ch].
4968 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * Added one new argument <user mode> to the WHOIS command reply
4971 to return the mode of the user in SILC. Updated the protocol
4974 Implemented it to the server and client.
4976 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Fixed the mode printing on the user interface on joining.
4979 Affected file silc/client_ops.c.
4981 * Implemented the UMODE command and user modes in general to the
4982 client library and to the user interface.
4984 * Implemented the UMODE command to the server.
4986 * The server now sends UNKNOWN_COMMAND error status if client sends
4987 unknown command. Affected file silcd/command.c.
4989 * All server commands now handle the command identifier the right
4990 way when sending the command reply to the client. The client can
4991 use to identify the command replies with the identifier.
4993 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * Added silc_server_get_client_route to resolve the route to
4996 the client indicated by the client ID. Affected file is
4999 * Added silc_server_relay_packet as general function to relay
5000 packet to arbitrary destination. This deprecates functions
5001 like _send_private_message_key, _relay_notify etc. Affected
5002 file is silcd/packet_send.[ch].
5004 Removed silc_server_send_key_agreement,
5005 silc_server_send_private_message_key and
5006 silc_server_packet_relay_notify functions from the file
5007 silcd/packet_send.[ch].
5011 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5012 server. Affected file silcd/packet_receive.[ch].
5014 * Implemented the KILL command to the client. Implemented the
5015 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5016 Affected files lib/silcclient/command[_reply].c and
5017 lib/silcclient/client_notify.c. Implemented the KILL notify
5018 printing in the user inteface.
5020 * Fixed a lot silc_parse_nick memory leaks from the client
5021 library in the file lib/silcclient/command.c.
5023 * Changed the silc_server_send_notify_on_channels's `sender'
5024 argument from SilcSocketConnection to SilcClientEntry to
5025 check the sender as entry and not as connection object and not
5026 to send to the client provided as argument. The affected file
5027 is silcd/packet_send.[ch].
5029 * The notify packets that are destined directly to the client used
5030 to not to be processed by the server. Now changed that and the
5031 server processes all notify packets. After relaying the packet
5032 to the client the notify packet is processed in the server.
5034 * The silc_server_free_client_data now checks whether there is
5035 pending outgoing traffic for the client and purges the data to
5036 the network before removing the client entry.
5038 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5041 an client is killed from the SILC Network. Updated the protocol
5044 Added new function silc_server_send_notify_killed to the
5045 silcd/packet_send.[ch].
5047 * Added function silc_server_packet_relay_notify to relay notify
5048 packets that are destined directly to a client. In this case
5049 the server does not process the notify packets but merely relays
5050 it to the client. Affected file silcd/packet_send.[ch].
5052 Added also silc_server_packet_process_relay_notify to check
5053 whereto relay the notify. Affected file is
5054 silcd/packet_receive.[ch].
5056 * Implemented the KILL command to the server.
5060 * Added the backup schema desgined last fall to the protocol
5061 specs for everyone to see. The specification is in the
5062 *-spec-xx.txt draft and the packet type definitions for the
5063 backup routers is in *-pp-xx.txt draft. Thusly, added also
5064 new packet type SILC_PACKET_CELL_ROUTERS.
5066 * A big security problem in the implementation discovered. The
5067 signoff of an client did not cause new channel key generation
5068 which it of course should've done. The channel keys must be
5069 always re-generated when client leaves (or signoffs) the channel.
5070 The silc_server_remove_from_channels funtion now handles
5071 the channel key re-generation.
5073 * Added `sender' argument to the silc_server_send_notify_on_channels
5074 to not to send the client provided as argument. Affected file
5075 silcd/packet_send.[ch].
5077 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Implemented OPER and SILCOPER commands into the server and
5082 * Added silc_auth_verify and silc_auth_verify_data to verify
5083 the authentication directly from the authentication payload.
5084 It supports verifying both passphrase and public key based
5085 authentication. Affected file lib/silccore/silcauth.[ch].
5087 * Added `hash' field to the SilcIDListData structure. It is the
5088 hash negotiated in the SKE protocol. Affected file is
5091 * Slight redesigning of the SilcAuthPayload handling routines.
5092 Do not send SilcPKCS but SilcPublicKey as argument.
5094 * Implemented the public key authentication support to the
5095 serverconfig. The public key is loaded from the provided path
5096 and saved as authentication data to void * pointer. Thus,
5097 changed the unsigned char *auth_data to void *auth_data;
5099 * Fixed SHUTDOWN command to send the reply before the server
5100 is shutdown. :) Affected file silcd/command.c.
5102 * Fixed fatal bug in CONNECT command. The hostname was invalid
5103 memory and server crashed. Affected file silcd/command.c.
5105 * Fixed fatal bug in CLOSE command. The server_entry became
5106 invalid but was referenced later in the command. Affected file
5109 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Fixed fatal bug in failure packet handling. Server ignored
5112 the failure and thus crashed when it came.
5116 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5118 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5119 that the command may be executed only once in (about) 2 seconds.
5120 The old SILC_CF_LAG flag is same but allows command bursts up
5121 to five before limiting.
5123 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5124 server code. Various commands now includes the CF_LAG_STRICT
5125 flag to disallow any kind of miss-use of the command.
5127 * Fixed the silc_buffer_unformat to not to allocate any data
5128 if the length of the data is zero. It used to allocate the
5129 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5131 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Changed the format of AdminConnection configuration section
5134 in the server. Added username of the admin to the format.
5135 Affected files silcd/serverconfig.[ch].
5137 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5138 to return admin configuration data by host, username and/or
5141 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Implemented WHOWAS command to the server. Added the functions:
5145 silc_server_command_whowas_parse,
5146 silc_server_command_whowas_send_reply,
5147 silc_server_command_whowas_from_client and
5148 silc_server_command_whowas_from_server
5150 * Added <Client ID> argument to the WHOWAS command reply. Updated
5151 the protocol specs accordingly.
5153 * Implemented WHOWAS command and command_reply to the client
5156 Implemented the WHOWAS printing on the user interface.
5158 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Added new argument to the WHOWAS command reply, the real name.
5161 It is an optional argument. Updated the protocol specs.
5163 * Added SilcIDCacheDestructor callback that is registered when
5164 the SilcIDCache is allocated. The callback is called when
5165 an cache entry in the ID Cache expires, or is purged from the
5166 cache. Added into lib/silccore/idcache.[ch].
5168 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5169 to destruct the client entries when the cache entry expires.
5170 Other ID Cache's in server and in the client library ignores
5173 * If the ID Cache entry's `expire' field is zero then the entry
5174 never expires. Added boolean `expire' argument to the
5175 silc_idcache_add function in the lib/silccore/idcache.[ch].
5176 If it is TRUE the default expiry value is used.
5178 * Added silc_server_free_client_data_timeout that is registered
5179 when client disconnects. By default for 5 minutes we preserve
5180 the client entry for history - for WHOWAS command.
5182 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Added support to the server to enforce that commands are not
5185 executed more than once in 2 seconds. If server receives
5186 commands from client more frequently, timeout is registered
5187 to process the commands. Affected file silcd/command.c.
5188 Added new function silc_server_command_process_timeout.
5190 * Changed NICK_NOTIFY handling in client library to check that
5191 if the client's nickname was changed, so there is no need to
5192 resolve anything from the server.
5194 * Removed error printing from the WHOIS and IDENTIFY commands.
5195 If error occurs then it is ignored silently in the client library.
5196 The application, however, may map the received error to
5197 human readable error string. The application currently maps
5198 the NO_SUCH_NICKNAME error to string.
5200 * Made the command status message public to the application. Moved
5201 them from lib/silcclient/command_reply.c to
5202 lib/silcclient/command_reply.h. The application can map the
5203 received command status to the string with the
5204 silc_client_command_status_message function.
5206 * Added check to the server to check that client's ID is same
5207 as the Source ID in the packet the client sent. They must
5210 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Added dist-bzip hook to the Makefile.am to make bzip2
5213 compressed distributions.
5215 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Server now enforces the maximum length for the nickname and
5218 the channel as protocol specification dictates. 128 bytes for
5219 nickname and 256 bytes for channel name.
5221 * Moved the WHOIS printing to the application. The client libary
5222 does not print out the WHOIS information anymore, the application
5223 must do it. Renamed silc_client_command_reply_whois_print to
5224 the silc_client_command_reply_whois_save.
5226 The client's idle time is also sent to the application now, and
5227 the idle is shown on screen.
5229 * Added silc_client_command_reply_identify_save to save the
5230 received IDENTIFY entries.
5232 * Do not check for channel private keys in message sending and
5233 reception if the channel does not have the PRIVKEY mode set.
5234 Affected file lib/silclient/client_channel.c.
5236 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5239 just surfaced after chaning the JOIN procedure.
5241 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Added silc_client_get_clients_by_list to get client entries
5244 from Client ID list, that is returned for example by JOIN
5245 and USERS command replies. The application should use this
5246 function for example when JOIN command reply is received to
5247 resolve the clients already on the channel (library does not
5248 do that anymore as USERS command reply is not used in the JOIN
5249 procedure anymore). Affected files lib/silcclient/silcapi.h and
5250 lib/silcclient/idlist.c.
5252 * JOIN command reply and USERS command reply returns now SilcBuffer
5253 pointers instead of unsigned char pointers when returning
5254 the client list and mode list.
5256 * Added <Client ID> argument to the JOIN command reply, mainly
5257 for the server to identify for which client the command was
5258 originally sent. Updated protocol specs accordingly.
5260 * Added SilcDlist private_key pointer to the SilcChannelEntry
5261 in the client to support the channel private keys. Affected
5262 file is lib/silcclient/idlist.h.
5264 * Added SilcChannelPrivateKey argument to the function
5265 silc_client_send_channel_message so that application can choose
5266 to use specific private ke if it wants to. If it is not provided,
5267 the normal channel key is used, unless private keys are set.
5268 In this case the first (key that was added first) is used
5269 as the encryption key.
5271 * Implemented the support for channel private key handling.
5272 Implemented the following functions:
5274 silc_client_add_channel_private_key,
5275 silc_client_del_channel_private_keys,
5276 silc_client_del_channel_private_key,
5277 silc_client_list_channel_private_keys and
5278 silc_client_free_channel_private_keys
5280 Affected file lib/silcclient/client_channel.c.
5282 * Added the support for the private keys in the channel message
5283 sending and encryption and in the message reception and
5284 decryption. Affected funtions are
5285 silc_client_send_channel_message and silc_client_channel_message.
5287 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5289 * Added SKE's key verify callback to the client library's
5290 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5292 * Removed the statement that server (or router) must send USERS
5293 command reply when joining to the channel so that the client
5294 knows who are on the channel. Instead, the client list and
5295 client's mode list is now sent in the JOIN command reply to the
5296 client who joined channel. This is better solution.
5298 * Added function silc_server_get_users_on_channel and function
5299 silc_server_save_users_on_channel to the silcd/server.[ch].
5301 * Removed function silc_server_command_send_users from the
5304 * Do not show topic on the client library anymore. The topic is
5305 sent in the command reply notify to the application and the
5306 application must show the topic now.
5308 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Added client searching by nickname hash into the IDENTIFY and
5311 WHOIS commands in the server as they were clearly missing from
5312 them. Affected file is silcd/command.c.
5314 * Fixed a bug in private message receiving in the client library.
5315 The remote ID was freed and it wasn't supposed, now it is
5318 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Minor fix to the channel payload; allocate the data area, as it
5321 needs to be of specific length.
5323 * If the key agreement port is zero then the operating
5324 system will define the bound port. Affected files are
5325 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5327 * Added new function silc_channel_payload_decrypt into the file
5328 lib/silccore/silcchannel.[ch].
5330 * Moved the channel message etc, check from silc_packet_decrypt
5331 to applications. The library calls now a generic
5332 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5333 when the packet is either normal or special. This was done to
5334 allow more wide range of checking that was not allowed when
5335 the code was in library. Now applications can do virtually any
5336 checks to the packet and return to the library the decision how
5337 the packet should be processed. Affected files are
5338 lib/silccore/silcpacket.[ch].
5340 Added silc_server_packet_decrypt_check to the server and
5341 silc_client_packet_decrypt_check to the client library.
5343 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5344 to send with specified source and destination information.
5346 * Channel message delivery between routers was broken after the
5347 channel key distribution was fixed earlier. The channel key
5348 was used be to distributed to other routers as well which is not
5349 allowed by the protocol. Now this is fixed and channel keys
5350 really are cell specific and the channel message delivery between
5351 routers comply with the protocol specification.
5353 * Fixed various commands in server to check also the global list
5354 for the channel entry and not just the local list. The affected
5355 file silcd/command.c.
5357 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5359 * Added assert()s to buffer formatting and unformatting routines
5360 to assert (if --enable-debug) when error occurs. Affected
5361 file: lib/silcutil/silcbuffmt.c.
5363 * Changed to auto-reconnect to check whether the remote host is
5364 router and register the re-connect timeout if it is. It used
5365 to check that whether we are normal server, but router must do
5366 auto-reconnect with another router as well. Affected file
5369 * Removed the [<key len>] option from CMODE command as the cipher
5370 name decides the key length, nowadays. See the defined ciphers
5371 from the protocol specification.
5373 * Added [<hmac>] option to the CMODE command to define the HMAC
5374 for the channel. Added SILC_CMODE_HMAC channel mode.
5376 * Added [<hmac>] option for the JOIN command so that user can
5377 select which HMAC is used to compute the MACs of the channel
5380 * Added Hmac field to the Channel Message Payload. The integrity
5381 of plaintext channel messages are now protected by computing
5382 MAC of the message and attaching the MAC to the payload. The
5383 MAC is encrypted. Now, it is clear that this causes some
5384 overhead to the size of the packet but rationale for this is that
5385 now the receiver can verify whether the channel message decrypted
5386 correctly and also when private keys are set for the channel the
5387 receiver can decrypt the packet with several keys and check from
5388 the MAC which key decrypted the message correctly.
5390 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5391 lib/silccrypt/silccipher.[ch].
5393 * Added silc_hash_len to return the digest length into the
5394 lib/silcrypt/silchash.[ch].
5396 * Rewrote parts of Silc Channel Payload interface in the
5397 lib/silccore/silcchannel.[ch]. The encode function now also
5398 encrypts the packet and parse function decrypts it.
5400 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5402 * Fixed a minor formatting bug in the SKE's key material processing.
5403 It actually might have processed the keys wrong way resulting
5406 * Redefined the mandatory HMAC algorithms and added new algorithms.
5407 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5408 and hmac-md5 truncated to 96 bits. The mandatory is now
5409 hmac-sha1-96. Rest are optional (including the one that used
5410 to be mandatory). Rationale for this is that the truncated HMAC
5411 length is sufficient from security point of view and can actually
5412 make the attack against the HMAC harder. Also, the truncated
5413 HMAC causes less overhead to the packets. See the RFC2104 for
5416 * Added new [hmac] configuration section. The SKE used to use
5417 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5418 is of course wrong. The official names that must be proposed in
5419 the SKE are the ones defined in the protocol specification
5420 (hmac-sha1-96 for example). The user can configure any hmac
5421 using any hash function configured in the [hash] section. At
5422 least, the mandatory must be configured.
5424 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5426 * Added HMAC list to the SKE proposal list. It has now both
5427 hash algorithm list and HMAC list. This makes the protocol
5428 incompatible with previous versions. The SKE now seems to work
5429 the way it is supposed to work, for the first time actually.
5431 * Defined plain Hash algorithms to the protocol specification.
5434 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5436 * Implemented support for key agreement packets into the server.
5437 Added functions silc_server_key_agreement and
5438 silc_server_send_key_agreement. Other than these functions,
5439 server has nothing to do with this packet.
5441 * Added support for private message key packets into the server.
5442 Added functions silc_server_private_message_key and
5443 silc_server_send_private_message_key.
5447 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5448 called in the protocol's final callback instead in the END
5449 protocol state. This makes a little more sense and in the same
5450 time in client we can use the same protocol routines for normal
5451 key exchange and to key agreement packet handling as well.
5453 * Added to both client's and server's KE protocol context the
5454 SilcSKEKeyMaterial pointer to save the key material. We will
5455 bring the key material to the protocol's final callback by doing
5456 this. The final callback must free the key material.
5458 * Added SKE's packet_send callback into client's KE protocol
5459 context so that the caller can choose what packet sending function
5460 is used. This way we can use different packet sending when
5461 doing normal SKE when doing key agreement packet handling (in
5462 the key agreement packet handling we do not want to encrypt
5465 * Implemented the responder side of the key agreement routines
5466 in the client. The client can now bind to specified port and
5467 accept incoming key negotiation. The key material is passed
5468 to the application after the protocol is over.
5470 * Implemented the processing of incoming Key Agreement packet
5471 in the client. Added function silc_client_key_agreement to
5474 * Implemented the intiator side of the key agreement routines
5475 in the client. The client can now initiate key agreement with
5476 another remote client. The key material is passed to the
5477 application after the protocol is over.
5479 * Created client_keyagr.c to include all the key agreement
5482 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5483 SILC_TASK_CALLBACK except that it is not static.
5485 * Created client_notify.c and moved the Notify packet handling
5486 from the client.[ch] into that file.
5488 * Created client_prvmsg.c and moved all private message and
5489 private message key routines from the client.[ch] into that file.
5491 * Create client_channel.c and moved all channel message and
5492 channel private key routines from the client.[ch] into that file.
5494 * Changed silc_client_get_client_by_id_resolve to resolve with
5495 WHOIS command instead of IDENTIFY command, in the file
5496 lib/silclient/idlist.c.
5498 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Implemented the SKE's responder side to the Client library.
5502 * When FAILURE is received to the protocol do not trust it
5503 blindly. Register a timeout to wait whether the remote closes
5504 the connection as it should do it, only after that process the
5505 actual failure. This was changed to both client and server.
5507 * Added client_internal.h to include some of the structures
5508 there instead of client.h in lib/silcclient/.
5510 * Added function silc_task_unregister_by_callback to unregister
5511 timeouts by the callback function.
5513 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Some "Incomplete WHOIS info" errors has been appearing on the
5516 log files. Took away the entry->userinfo check from WHOIS
5517 reply sending. The entry->userinfo is now " " if client did not
5518 provide one. I thought this was fixed earlier but something
5519 is wrong still. Let's see if the error still appears.
5521 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Fixed a minor bug in the login when the channel key is
5524 re-generated in the server. It used to generate the key in
5525 wrong order and thus caused problems in the channel traffic.
5527 * Fixed a minor bug in channel key distsribution after
5528 KICK command. The key was not sent to the router even though
5531 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5533 * Added silc_ske_process_key_material_data as generic routine
5534 to process any key material as the SILC protocol dictates. The
5535 function is used by the actual SKE library but can be used by
5536 applications as well. This relates to the private message keys
5537 and the channel private keys since they must be processed the
5538 same way the normal SILC session keys. The protocol dictates
5539 this. Affected files: lib/silcske/silcske.[ch].
5541 Added also silc_ske_free_key_material to free the
5542 SilcSKEKeyMaterial structure.
5544 * Defined silc_cipher_set_key function to set the key for
5545 cipher without using the object's method function. The affected
5546 files: lib/silccrypt/silccipher.[ch].
5548 * Implemented silc silc_client_add_private_message_key,
5549 silc_client_add_private_message_key_ske,
5550 silc_client_del_private_message_key,
5551 silc_client_list_private_message_keys and
5552 silc_client_free_private_message_keys functions in the
5555 Added functions silc_client_send_private_message_key to send
5556 the Private Message Key payload and silc_client_private_message_key
5557 to handle incoming Private Message Key payload.
5559 * Added Cipher field to the Private Message Key payload to set
5560 the cipher to be used. If ignored, the default cipher defined
5561 in the SILC protocol (aes-256-cbc) is used.
5563 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Removed lib/silcclient/ops.h file.
5567 Redefined parts of the SILC Client Library API. Created new
5568 file silcapi.h that deprecates the ops.h file and defines the
5569 published Client Library API. Defined also private message key
5570 API and channel private key API into the file.
5572 This is the file that the application must include from the
5573 SILC Client Library. Other files need not be included by
5574 the application anymore.
5576 * Added new key_agreement client operation callback and also
5577 defined the Key Agreement library API for the application.
5579 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5582 is used by clients to request key negotiation between another
5583 client in the SILC network. If the negotiation is started it
5584 is performed using the SKE protocol. The result of the
5585 negotiation, the secret key material, can be used for example
5586 as private message key.
5588 Implemented the Key Agreement payload into the files
5589 lib/silccore/silauth.[ch].
5591 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Redefined ciphers for the SILC protocol. Added some new ciphers
5594 and defined the key lengths for the algorithms. Changed the
5595 code accordingly. The default key length is now 256 bits.
5597 * Fixed SKE key distribution function silc_ske_process_key_material
5598 when the key length is more than 128 bits. The default key
5599 length in SILC is now 256 bits.
5601 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5602 to indicate unsupported algorithm.
5604 * Renamed rijndael.c to aes.c and all functions as well.
5606 * Fixed a long standing channel key setting bug in client library.
5607 Weird that it has never surfaced before.
5609 * Fixed bug in channel deletion. If the entire channel is removed
5610 then it must also delete the references of the channel entry
5611 from the client's channel list as the client's channel entry and
5612 the channel's client entry share same memory.
5614 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Implemented CONNECT and SHUTDOWN commands in the client.
5618 * Implemented CLOSE command to the client.
5620 * Added the function silc_idlist_find_server_by_name into the
5621 files silcd/idlist.[ch].
5623 Added the function silc_idlist_find_server_by_conn into the
5624 files silcd/idlist.[ch].
5626 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * DIE command was renamed to SHUTDOWN. Updated the both code
5631 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5632 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5634 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5637 * Added function silc_server_create_connection function to create
5638 connection to remote router. My server implementation actually
5639 does not allow router to connect to normal server (it expects
5640 that normal server always initiates the connection to the router)
5641 so the CONNECT command is only good for connecting to another
5644 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5647 or some other client was kicked from the channel.
5649 Implemented the handling of the notify type to both client
5652 Implemented silc_server_send_notify_kicked to send the KICKED
5653 notify. It is used to send it to the server's primary router.
5655 * Implemented the KICK command into server and client.
5657 * Added `query' argument to the silc_idlist_get_client function
5658 to indicate whether to query the client from server or not if
5661 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5662 to indicate that the client is not channel founder.
5666 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * Removed the rng context from SilcPacketContext structure and
5669 changed that the packet routine uses the Global RNG API.
5671 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5673 * Added support for quit message that client can "leave" on the
5674 channel when it quits the SILC. It is ditributed inside the
5675 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5677 Added silc_server_free_client_data that will take the
5678 signoff message as argument.
5680 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5682 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5684 * Updated parts of the protocol specification to keep it up
5687 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5689 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5690 payloads in one packet.
5692 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5693 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5694 use now the new List flag.
5696 * Also deprecated the following packet types: REPLACE_ID,
5697 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5699 * Added list support for Notify packet in server.
5701 * Added silc_server_send_notify_channel_change to send the
5702 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5703 the silc_server_send_replace_id.
5705 * Added silc_server_send_notify_nick_change to send the
5706 NICK_CHANGE notify type. Deprecates the function
5707 silc_server_send_replace_id.
5709 * Added silc_server_send_notify_join to send the JOIN notify type.
5710 Deprecates the function silc_server_send_new_channel_user.
5712 * Added silc_server_send_notify_leave to send LEAVE notify type.
5713 Deprecates the function silc_server_send_remove_channel_user.
5715 * Added silc_server_send_notify_cmode and
5716 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5717 types. Deprecates the silc_server_send_set_mode function.
5719 * Added SERVER_SIGNOFF notify type to indicate that server has
5720 quit. This means that all clients on the channel from that
5721 server will drop. This can be also used when netsplit happens.
5723 Deprecated REMOVE_ID packet type since it is not needed anymore
5726 Added silc_server_send_notify_server_signoff to send the
5727 SERVER_SIGNOFF notify type. Deprecates the function
5728 silc_server_send_remove_id.
5730 Added also silc_server_send_notify_signoff to send the
5731 SIGNOFF notify type.
5733 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5734 SILC protocol from this day on. Changed the protocol
5735 specification as well.
5737 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5738 notify type. It is used between routers to notify about
5739 topic changes on a channel.
5741 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5744 * Partly updated the protocol specification to comply with the
5745 changes now made. It is still though a bit outdated.
5747 * The JOIN notify type now takes one extra argument <Channel ID>.
5748 The packet used to be destined to the channel but now the
5749 JOIN type may be sent as list thus it is impossible to
5750 destine it to any specific channel. By adding this argument
5751 it is again possible.
5753 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * Added CREDITS file. The CHANGES and CREDITS file will appear
5756 in the distribution as well.
5758 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5761 types in the server's silcd/packet_receive.c.
5763 * Implemented CMODE and CUMODE to work in router environment.
5765 * Fixed minor encoding and decoding buglet from the
5766 lib/silccore/silcmode.c.
5768 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5771 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5773 * Changed all SilcConfigServer* and silc_config_server* to
5774 SilcServerConfig* and silc_server_config*, respectively.
5777 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5779 * Associated the ID (client or server ID) to the Authentication
5780 Payload to avoid any possibility of forging. Updated the
5781 protocol specification and the code accordingly.
5783 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5785 * The RSA key length is now save to the RsaKey context in the
5786 key generation process in lib/silccrypt/rsa.c. The key length
5787 is now used to figure out the maximum size of the block allowed
5788 to be encrypted/signed.
5790 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5791 is equivalent to the silc_mp_mp2bin but does not allocate any
5794 * Changed silc_mp_mp2bin API to take length argument. If it is
5795 non-zero then the buffer is allocated that large. If zero, then
5796 the size is approximated using silc_mp_sizeinbase, which however
5799 * Created Global RNG API which is global RNG that application can
5800 initialize. After initializing, any routine anywhere in the
5801 code (including library) can use RNG without allocating a new
5802 RNG object. This was done to allow this sort of use of the
5803 RNG in code that has no chance to allocate RNG object. All
5804 applications currently allocate this and many routines in the
5805 library use this. Affected file lib/silccrypt/silcrng.[ch].
5807 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5808 it to use the Global RNG API.
5810 * Defined Authentication Payload into protocol specification that
5811 is used during SILC session to authenticate entities. It is
5812 used for example by client to authenticate itself to the server
5813 to obtain server operator privileges.
5815 Implemented this payload into the lib/silccore/silcauth.[ch].
5816 Implemented also routines for public key based authentication
5817 as the new protocol specification dictates.
5819 Moved definitions of different authentication methods from
5820 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5822 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5823 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5824 silc_pkcs_verify_with_hash functions into the file
5825 lib/silccrypt/silcpkcs.[ch].
5827 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5829 * The client entry's userinfo pointer must be always valid.
5830 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5831 will fail since it requires the userinfo. Now, the userinfo
5832 is allocated as "" if actual userinfo does not exist. Actually,
5833 it must exist and it is totally Ok to drop client connections
5834 that does not announce the userinfo. However, we will make
5835 this workaround for now.
5837 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5838 to return the remote port by socket.
5840 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5843 SILC_SERVER_PENDING_EXEC and added an new macro
5844 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5845 data or when error occurs while processing the pending command.
5847 Added new argument `destructor' into silc_server_command_pending
5848 and to the SilcServerCommandPending object. This destructor is
5849 now called after calling the pending callback or if error occurs
5850 immediately. If error occurs the actual pending callback won't
5851 be called at all - only the destructor. The destructor may be
5852 NULL if destructor is not needed.
5854 All this applies for client library code as well. Similar
5855 changes were made there as well for the pending commands.
5857 In the client, the application must now allocate the
5858 SilcClientCommandContext with the silc_client_command_alloc
5861 * Added reference counter to the SilcServerCommandContext. Added
5862 function silc_server_command_alloc and silc_server_command_dup
5865 Same type of functions added to the client library for the same
5868 * Removed the cmd_ident from IDListData away since it is now
5869 global for all connections. It is the command identifier used
5870 in command sending and with pending commands. The affected file
5873 * Added reference counter to the SilcSocketConnection objecet to
5874 indicate the usage count of the object. The object won't be
5875 freed untill the reference counter hits zero. Currently only
5876 server uses this, and client ignores it. The client must be
5877 set to use this too later. The affected files are
5878 lib/silccore/silcsockconn.[ch]. Added also the function
5879 silc_socket_dup to increase the reference counter.
5881 This was mainly added because it is possible that the socket
5882 is removed underneath of pending command or other async
5883 operation. Now it won't be free'd and proper DISCONNECTING
5884 flags, etc. can be set to avoid sending data to connection that
5885 is not valid anymore.
5887 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5888 the connection. After that it sets SILC_SET_DISCONNECTED.
5889 It is, however, possible that the socket data is not still freed.
5890 The silc_server_packet_process now checks that data is not
5891 read or written to connection that is DISCONNECTED. The socket
5892 get's freed when the reference counter hits zero.
5894 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * Changed the client operation API: channel_message operation's
5897 `sender' is now the client entry of the sender, not the nickname
5898 and the `channel' is the channel entry, not the channel name.
5900 In the private_message operation the `sender' is now also the
5901 client entry of the sender not the nickname.
5903 Affected file is lib/silcclient/ops.h and all applications
5904 using the client operations.
5906 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Moved the calling of ops->connect() from connect_to_server_final
5909 into receive_new_id functin since that is the point when the
5910 client is actually allowed to send traffic to network. The
5911 affected file is lib/silcclient/client.c.
5913 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5916 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5917 (if needs broadcasting) instead of broadcasting the packets one
5918 by one which would make a burst in the network traffic.
5920 * Added `broadcast' argument to the functions in silcd/server.[ch]
5921 silc_server_create_new_channel[_with_id] to indicate whether
5922 to send New Channel packet to primary router.
5924 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Added new function into the silcd/server.[ch] files:
5927 silc_server_create_new_channel_with_id to create new channel with
5928 already existing Channel ID.
5930 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5931 lib/silccore/silcpacket.h. This packet is used t send list of
5932 Set Mode payloads inside one packet. Server uses this to set
5933 the modes for the channels and clients on those channels, that it
5934 announced to the router when it connected to it. The protocol
5935 specification has been updated accordingly.
5937 * The silc_server_new_channel did not handle the packet coming
5938 from normal server as it normally does not send that. However,
5939 when it announces its channels it does send it. Implemented
5940 the support for that.
5942 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5943 into the file lib/silccore/id.h.
5945 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5947 * Fixed memory leaks in the functions silc_idlist_del_client,
5948 silc_idlist_del_channel and silc_idlist_del_server in the file
5949 silcd/idlist.c. All of those leaked like a sieve.
5951 * Fixed some small memory leaks in the client's function
5952 silc_client_notify_by_server.
5954 * Added functions into silcd/server.c: silc_server_announce_clients,
5955 silc_server_announce_channels and silc_server_announce_server.
5956 These functions are used by normal and router server to announce
5957 to its primary router about clients, channels and servers (when
5958 router) that we own. This is done after we've connected to the
5961 These functions effectively implements the following packet types:
5962 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5963 and SILC_PACKET_NEW_ID_LIST.
5965 * Added new functions into the silcd/packet_receive.[ch]:
5966 silc_server_new_id_list, silc_server_new_channel_list and
5967 silc_server_new_channel_user_list to handle the incoming
5968 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5970 * Added support of changing Channel ID in the function
5971 silc_server_replace_id. If the server that announces a channel
5972 to the router already exists in the router (with same name but
5973 with different Channel ID), router is responsible to send
5974 Replace ID packet to the server and force the server to change
5975 the Channel ID to the one router has.
5977 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5978 client that the Channel ID has been changed by the router. The
5979 normal server sends this to the client. Client must start using
5980 the new Channel ID as the channel's ID.
5982 Implemented handling of this new type into lib/silcclient/client.c
5983 into the function silc_client_notify_by_server.
5985 * Added new function silc_idlist_replace_channel_id into the files
5986 silcd/idlist.[ch] to replace the Channel ID.
5988 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Call silc_server_command_identify_check always when processing
5991 the IDENTIFY command in silcd/command.c
5993 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5996 send keepalive packets. The packet can be sent by clients,
5997 servers and routers.
5999 Added function silc_socket_set_heartbeat into the file
6000 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6001 If not set, the heartbeat is not performed. The actual
6002 heartbeat is implemented in the low level socket connection
6003 library. However, application is responsible of actually
6006 Added silc_server_send_heartbeat to send the actual heartbeat
6007 packet into silcd/packet_send.[ch]. Server now performs
6008 keepalive with all connections.
6010 * Added silc_task_get_first function into lib/silcutil/silctask.c
6011 to return the timeout task with shortest timeout. There was a bug
6012 in task unregistration that caused problems. TODO has been
6013 updated to include that task system must be rewritten.
6015 * The client library will now resolve the client information when
6016 receiving JOIN notify from server for client that we know but
6017 have incomplete information.
6019 * Rewrote parts of silc_server_remove_from_channels and
6020 silc_server_remove_from_one_channel as they did not remove the
6021 channel in some circumstances even though they should've.
6023 * Encryption problem encountered in server:
6025 The LEAVE command used to send the Channel Key packet to the
6026 router immediately after generating it. However, the code
6027 had earlier sent Remove Channel user packet but not immediately,
6028 ie. it was put to queue. The order of packets in the router
6029 was that Channel Key packet was first and Remove Channel User
6030 packet was second, even though they were encrypted in the
6031 reverse order. For this reason, MAC check failed. Now, this
6032 is fixed by not sending the Channel Key packet immediately but
6033 putting it to queue. However, this is more fundamental problem:
6034 packets that are in queue should actually not be encrypted
6035 because packets that are sent immediately gets encrypted
6036 actually with wrong IV (and thus MAC check fails). So, packets
6037 that are in queue should be encrypted when they are sent to
6038 the wire and not when they put to the queue.
6040 However, the problem is that the current system has not been
6041 designed to work that way. Instead, the packet is encrypted
6042 as soon as possible and left to the queue. The queue is then
6043 just purged into wire. There won't be any fixes for this
6044 any time soon. So, the current semantic for packet sending
6047 o If you send packet to remote host and do not force the send
6048 (the packet will be in queue) then all subsequent packets to the
6049 same remote host must also be put to the queue. Only after the
6050 queue has been purged is it safe again to force the packet
6053 o If you send all packets immediately then it safe to send
6054 any of subsequent packets through the queue, however, after
6055 the first packet is put to queue then any subsequent packets
6056 must also be put to the queue.
6058 Follow these rules and everything works fine.
6060 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6062 * Added new function silc_server_remove_clients_by_server to
6063 remove all client entries from ID list when the server connection
6064 is lost. In this case it is also important to invalidate all
6065 client entires as they hold the invalid server entry. This
6066 fixes fatal bug when server has lost connection and will reconnect
6069 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6071 * Made some sanity checks to silc_server_daemonise like to check
6072 whether the requested user and group actually exists.
6074 * Added sanity check to SKE's silc_ske_responder_finish to check
6075 that the public and private key actually is valid.
6077 * Invalidate the client's nickname when receiving Replace ID
6078 packet and the Client ID is being replaced. This means that the
6079 server will query the nickname if someone needs it (client)
6082 * Sort the ID Cache in client library when the ID Cache data
6083 has changed (needs sorting).
6085 * Do not allow for SILC client to create several connections to
6086 several servers. The client does not support windows right now
6087 and generating multiple connections causes weird behaviour.
6089 Irssi-silc client does support windows and can handle several
6090 connections without problems, see: www.irssi.org and SILC plugin.
6092 * Fixed some places where client was added to the IDList. The
6093 rule of thumb is following (in order to get everything right):
6094 If the client is directly connected local client then the
6095 `connection' argument must be set and `router' argument must be
6096 NULL to silc_idlist_add_client function. If the client is not
6097 directly connected client then the `router' argument must
6098 bet set and the `connection' argument must be NULL to the
6099 silc_idlist_add_client function.
6101 * The funtion silc_server_packet_send_local_channel actually did
6102 not check whether the client was locally connected or not. It
6103 does that now. Fixed a bug related to LEAVE command.
6105 * Fixed Remove Channel User payload parsing bug in server's
6106 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6108 * The server's silc_server_save_channel_key now checks also the
6109 global ID list for the channel as it might not be in the local
6110 list. Fixed a bug related to LEAVE command.
6112 * Is this the end of the [<unknown>] buglet that has been lurking
6113 around for a long time? A little for loop fix in server's
6114 silc_server_command_whois_parse that is used by both IDENTIFY
6115 and WHOIS command. At least, this was a clear bug and a cause
6116 of one type of [<unknown>] buglet.
6118 * WHOIS and IDENTIFY commands call the function
6119 silc_server_command_[whois/identify]_check function even if
6120 we are not router server.
6122 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Added --with-gmp configuration option. If set the GMP
6125 is always compiled in the SILC source tree. If not set then
6126 it is checked whether the system has the GMP3 installed. If
6127 it has then the GMP won't be compiled (the system's headers
6128 and library is used), if it doesn't have it then the GMP is
6129 compiled in the SILC source tree.
6131 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6133 * Changed RSA private exponent generation to what PKCS #1
6134 suggests. We try to find the smallest possible d by doing
6135 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6136 not security fix but optimization.
6138 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Added new config entry [Identity] to fork the server and run
6141 it as specific user and group. A patch from Bostik.
6143 * Imported Dotconf configuration library into lib/dotconf.
6144 This will be used to create the SILC configuration files later.
6145 It will appear in the distsribution after this commit.
6147 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6149 * A big code auditing weekend happening. Auditing code for
6150 obvious mistakes, bugs and errors. Also, removing any code
6153 Removed files for being obsolete:
6155 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6156 inline in the file lib/silcutil/silcbuffer.h)
6158 o lib/silcutil/silcbufutil.c (the header has inline versions)
6160 Changed code to fix possible error conditions:
6162 o The buffer formatting routines now check that the destination
6163 buffer really has enough space to add the data. This applies for
6164 both buffer formatting and unformatting
6165 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6166 unformatting was changed to accomodate following rules:
6167 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6168 sent to the function while XXX_*STRING will not allocate or copy
6169 the data into the buffer. Instead it sets the pointer from the
6170 buffer into the pointer sent as argument (XXX_*STRING used to
6171 require that the pointer must be allocated already). This change
6172 makes this whole thing a bit more consistent and more optimized
6173 (note that the data returned in the unformatting with XXX_*STRING
6174 must not be freed now). The routines return now -1 on error.
6176 o Tried to find all code that use buffer_format and buffer_unformat
6177 and added return value checking to prevent formatting and
6178 especially unformatting errors and possible subsequent fatal
6181 o Changed ske->x and ske->KEY to mallocated pointers in
6182 lib/silcske/silcske.h. Fixed possible data and memory leak.
6184 o Added return value checking to all *_parse* functions. Fixed
6185 many memory leaks as well.
6187 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6188 so that buffer overflows would not happen. All code now also
6189 checks the return value as it can fail.
6191 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6193 * Added reconnection support to server if the normal server looses
6194 its connection to the router (for example if router is rebooted).
6195 The server performs normal reconnection strategy implemented
6196 to the server. Affected file silcd/server.c.
6198 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6200 * Added new packet type SILC_PACKET_SET_MODE that is used to
6201 distribute the information about changed modes (for clients,
6202 channels and clients channel modes) to all routers in the
6203 network. Updated the protocol specification accordingly.
6205 Added functions into silcd/packet_send.c and
6206 silcd/packet_receive.c: silc_server_send_set_mode,
6207 silc_server_set_mode.
6209 Added new files silcmode.[ch] into lib/silccore that implements
6210 the encoding and decoding of Set Mode Payload. Added new type
6211 SilcSetModePayload. Moved the definitions of different modes
6212 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6214 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6216 * Oops, a little mistake in server's connection authentication
6217 protocol. The protocol is not ended with FAILURE but with
6218 SUCCESS if the authentication is Ok. :) Affected file is
6221 * Implemented NICK_CHANGE notify handling in server in the file
6222 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6223 the local clients on the channel. After the changing nickname
6224 in router environment snhould work and the [<unknown>] nickname
6225 should appear no more.
6227 The silc_server_replace_id function that receives the Replace ID
6228 payload now sends the NICK_CHANGE notify type also in the file
6229 silcd/packet_receive.c
6231 * Changed WHOIS and IDENTIFY command to support the maximum amount
6232 of arguments defined in protocol specs (3328 arguments). This
6233 fixed a bug that caused problems when there were more than three
6236 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6238 * Added extra parameter, command identifier, to the
6239 silc_client_send_command so that explicit command identifier
6242 Changed that ID list routines uses specific command identifier
6243 when sending WHOIS/IDENTIFY requests to the server so that they
6244 can be identified when the reply comes back.
6246 Affected files lib/silcclient/command.[ch],
6247 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6249 * Added `sender' argument to silc_server_packet_send_to_channel
6250 to indicaet the sender who originally sent the packet to us
6251 that we are now re-sending. Ignored if NULL. Affected file
6252 silcd/packet_send.[ch].
6254 * Added some server statistics support in silcd/server_internal.h
6255 SilcServerStatistics structure and around the server code. Also
6256 send some nice statistics information when client is connecting
6259 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Fixed channel ID decoding in server's JOIN command reply in
6262 silcd/command_reply.c
6264 * Fixed braodcasting of replace ID payload to not to send it if
6265 we are standalone server in silcd/packet_receive.c.
6267 * Fixed all channel message sending routines to not to send
6268 packets to clients that has router set, since they are routed
6269 separately in the same function earlier. Affects file
6270 silcd/packet_send.c and all channel packet sending functions.
6272 * In USERS reply, res_argv[i] are not allocated, the table
6273 is allocated. Thus changed that free the table, not its
6276 * In server's whois_check and identify_check if the client is
6277 locally connected do not send any WHOIS commands - they are not
6280 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6282 * Fixed some minor bugs in client when sending WHOIS command. The
6283 arguments was in wrong order.
6285 * Removed statis function add_to_channel from server in
6286 silcd/command.c that was previously used with the joining but
6289 * Tested USERS command in router environment successfully with two
6290 routers, two servers and two clients.
6292 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6294 * Reorganized the USERS command and command reply in client library
6295 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6296 When the command is given by user we register a pending command
6297 callback that will reprocess the command after the reply has been
6298 received from the server. When reprocessing the packet we then
6299 display the information. Thus, the USERS information is displayed
6300 now in the command callback instead of in the command reply
6301 callback. The processing of the command is same as previously
6302 when server has sent the command reply in the JOINing process.
6304 * Added to USERS command in silcd/command_reply.c to join the client,
6305 we didn't use to know about, to the channel after we've created
6306 a client entry for it. Also, for clienet we did know already still
6307 check whether it is on the channel or not and add it if not.
6309 * Removed silc_server_command_join_notify as the function and its
6312 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Changed the client's pending command handling to the same as the
6315 server's pending command handling. It is also now possible to
6316 execute command reply functions from other command reply
6317 function as the function callbacks for commands and command
6318 replies are one and same. The pending commands are not static
6319 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6320 in client connection context. Thus, pending commands are server
6321 connection specific as it is convenient.
6323 Changed the function silc_client_command_pending and
6324 silc_client_command_pending_del and added new function
6325 silc_client_command_pending_check. Removed the
6326 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6329 * Added cmd_ident, current command identifier, to the client
6330 connection context in lib/silcclient/client.h to keep track on
6331 command identifiers used in command sending. Client's command reply
6332 function handling now supports the mandatory command identifiers.
6334 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6335 funtions in client to fully support pending command callbacks.
6337 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6338 as one of the arguments to the application in the command reply
6341 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6342 before first releasing SILC but came back. Now it is removed again
6343 and should come back nomore. The FORWARDED flag was used only
6344 by the JOINing procedure by forwarding the command packet to router.
6345 Now, the JOINing procedure has been changed to more generic (due
6346 to various router environment issues) and FORWARDED is not needed
6347 anymore for anything. The protocol specification is yet to be
6350 Now, removed silc_server_packet_forward from server and the flag
6351 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6353 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * Renamed NAMES command to USERS command. The NAMES was named that
6356 due to historical reasons. Now it is renamed. Also, rewrote
6357 parts of the USERS command. The nickname list is not sent anymore
6358 by the server. Only Client ID and mode lists are sent in the USERS
6359 command. Changed this also to the protocol specification.
6361 The client now resolves the names and stuff after it receives
6362 the USERS list from the server when joining to the channel.
6364 * WHOIS and IDENTIFY commands has been changed to support multiple
6365 Client ID's per command. One can now search for multiple users
6366 in the network by sending only one WHOIS or IDENTIFY command.
6367 Changed the code and the protocol specifications.
6369 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6370 uses silc_server_command_whois_parse to parse the request. */
6372 * If normal server, do not parse the WHOIS and IDENTIFY requests
6373 before sending it to the router. Saves some time.
6375 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6377 * Fixed JOIN command on client library. Wrong number of arguments
6378 used to crash the client.
6380 * Added silc_server_channel_has_global function to check whether
6381 channel has global users or not.
6383 * Added silc_server_channel_has_local function to check whether channel
6384 has locally connected clients on the channel.
6386 * The silc_server_remove_from_one_channel now checks whether the
6387 channel has global users or not after given client was removed from
6388 the channel. It also checks whether the channel has local clients
6389 on the channel anymore. If it does not have then the channel entry
6390 is removed as it is not needed anymore.
6392 * The silc_server_notify now checks on JOIN notify whether the joining
6393 client is one of locally connected or global. If it is global then
6394 the channel has now global users on the channel and that is marked
6395 to the channel entry. Also, it now saves the global client to
6396 global list who is joining and JOINs it to the channel. This is
6397 for normal server, that is.
6399 Changed silc_server_send_notify_on_channel,
6400 silc_server_packet_relay_to_channel and
6401 silc_server_packet_send_to_channel check if we are normal server
6402 and client has router set (ie. global client) do not send the
6403 message to that client, as it is already routed to our router.
6405 * Implemented LEAVE notify type handling in silc_server_notify
6408 * Tested LEAVE command in router environment successfully. Tested
6409 with two routers, two servers and two clients.
6413 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6415 * Implemented SIGNOFF notify type handling in silc_server_notify
6418 * silc_server_remove_id now removes the client entry from all channels
6419 it has joined and thusly sends SIGNOFF notify type.
6421 * Rewrote the NAMES list generation in server by removing two excess
6422 loops. The lists are created now inside one loop.
6424 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * silc_server_remove_channel_user checks now also global list
6427 for channel and client.
6429 * silc_server_new_channel_user checks now both local and global
6430 list for channel and client. Fixed a bug in client id decoding.
6431 Used to decode wrong buffer.
6433 * silc_server_channel_message checks now both local and global
6434 list for channel entry.
6436 * Tested channel joining (hence JOIN) in router environment
6437 successfully. Tested with two routers, two servers and two
6440 * Tested channel message sending in router environment successfully.
6442 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6444 * Added silc_server_save_channel_key into server.[ch] to save the
6445 received channel key in Channel Key payload processing. It is
6446 also used in JOIN command reply handling.
6448 Equivalent function silc_client_save_channel_key added into
6449 client.[ch] into client library.
6451 * Changed JOIN command reply to send information whether the channel
6452 was created or not (is existing already) and the channel key
6453 payload. Changed protocol specs accordingly.
6455 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6456 the request was sent by ID and not by nickname. Crashed on
6459 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6462 now correctly save the received data.
6464 * silc_server_free_sock_user_data now notifies routers in the
6465 network about entities leaving the network.
6467 At the same time implemented functions silc_server_remove_id
6468 and silc_server_send_remove_id to receive and send REMOVE_ID
6469 packets. The packet is used to notify routers in the network
6470 about leaving entities. The ID removed will become invalid in
6473 * Added function silc_idlist_del_server into server. Removes and
6474 free's server entry from ID list.
6476 * silc_server_private_message function now checks, if we are router,
6477 that the destination ID really is valid ID, naturally.
6479 * In router when NEW_ID packet is received (for new client) the
6480 hash of the Client ID is saved in the ID Cache but the
6481 client->nickname is set to NULL, instead of putting the hash
6484 IDENTIFY command now also checks that client->nickname must be
6485 valid. If it is not if will request the data from the server who
6486 owns the client. Added new function
6487 silc_server_command_identify_check.
6489 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6490 to set the command to already allocated Command Payload.
6492 * Tested private message sending in router environment with two
6493 routers, two servers and two clients. Fixed minor bugs and now
6496 * Fixed segfault from client's NAMES command. Used to crash if
6499 * Forwarded packets must not be routed even if it is not destined
6500 to the receiver. Changed server code comply with this.
6502 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * Added `require_reverse_mapping' boolean value to ServerParams
6505 structure. If TRUE (not default) the server will require that
6506 the connecting host has fully qualified domain name.
6508 If the reverse mapping is not required and hostname could not be
6509 found the IP address is used as hostname.
6511 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6513 * Implemented version string checking to both client and server.
6514 The check is incomplete currently due to the abnormal version
6515 strings used in development version of SILC.
6517 * Changed all command functions in server to use the new
6520 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6522 * Changed char *data to unsigned char *data in ID Cache system to
6523 support binary data as ID Cache data. Changed code to support
6524 binary data in lib/silccore/idcache.c.
6526 * Renamed silc_server_packet_relay_command_reply to
6527 silc_server_command_reply as it is normal packet receiving
6528 function. Rewrote the function to accept command replys for
6529 servers and not only for clients.
6531 * Mark remote router always as registered server if we are connecting
6532 to it. Otherwise, commands sent by the router to us are ignored.
6534 * All ID List find routines now returns the ID Cache Entry pointer
6535 as well if requested.
6537 * WHOIS command works now in router environment, tested with two
6538 routers, two servers and two clients.
6540 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6541 in router environment (as it is almost equivalent to WHOIS) but
6542 hasn't been tested thoroughly. Added new functions:
6544 silc_server_command_identify_parse
6545 silc_server_command_identify_send_reply
6546 silc_server_command_identify_from_client
6547 silc_server_command_identify_from_server
6549 * Disabled route cache adding because adding two different ID's with
6550 same IP replaces the old cache entry thus giving wrong route.
6551 The entry->router->connection is always the fastest route anyway
6552 so route cache may not be needed. Of course, new routes maybe
6553 established after receiving the ID when the entry->router->connection
6554 might not be anymore the most optimal.
6556 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6558 * Add route cache for received ID for fast routing.
6560 * Added silc_server_packet_route to route received packet on router
6561 that is not destined to us.
6563 * Renamed silc_server_get_route to silc_server_route_get.
6565 * Added id_string and id_string_len fields into SilcServer to
6566 include encoded ServerID for fast comparing without excess
6567 encoding of the ID's.
6569 * Cleaned up WHOIS command on server side. Added following static
6572 silc_server_command_whois_parse
6573 silc_server_command_whois_check
6574 silc_server_command_whois_send_reply
6575 silc_server_command_whois_from_client
6576 silc_server_command_whois_from_server
6578 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6579 arguments in command replies. All command functions should be
6580 updated to use this macro.
6582 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6584 * Minor typo fixes on command reply handling on server.
6586 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6588 * Added silc_server_command_add_to_channel internal routine to add
6589 the client to the channel after router has created the channel and
6590 sent command reply to the server.
6592 * Added generic silc_server_send_command to send any command from
6595 * Use static buffer with ID rendering instead of duplicating data.
6597 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6599 * Fixed a channel user mode bug when joining to a channel server gave
6600 everybody channel founder rights, oops.
6602 * We mark ourselves as the router of the incoming server connection
6603 if we are router ourselves. This way we can check in some packet
6604 sending functions whether it is locally connected server. For
6605 incoming router connections we put NULL.
6607 * For router sending packets locally means now always sending the
6608 packet cell wide; to local clients and local servers. For normal
6609 server sending packet locally means sending it to only local
6612 * Fixed the JOIN command to really work in router environment. If the
6613 channel is created it is always created by the router. Router is
6614 also responsible of making the initial joining to the channel,
6615 sending JOIN notify to the sending server and distributing
6616 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6617 does not exist server doesn't do anything else but forward the
6618 command to the router which performs everything.
6620 * Added silc_server_send_channel_key function to send the Channel Key
6623 * Added silc_server_create_channel_key to create new channel key. The
6624 channel key is now re-generated everytime someone joins or leaves
6625 a channel, as protocol dictates. Note: channel->key_len is the
6628 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6631 packet_receive.[ch] to separate packet sending and receiving
6632 routines. The server.[ch] now includes everything else including
6633 actual packet processing (writing and reading data) and other
6636 Renamed silc_server_private_message_send_internal to
6637 silc_server_send_private_message. The routine is still though
6638 used only to relay private messages as server does not send
6639 private messages itself.
6641 Renamed silc_server_new_channel to silc_server_create_new_channel
6642 and added new function sicl_server_new_channel that handles the
6643 incoming New Channel packet. Added also new sending function
6644 silc_server_send_new_channel to send New Channel Payload.
6646 * Added new function silc_server_notify to process incoming notify
6647 packet to the server/router. Server may then relay the notify
6648 to clients if needed.
6650 * Added new function silc_server_new_channel_user to process incoming
6651 New Channel User packet. Router will redistribute the packet and
6652 send JOIN notify to its local clients and locally connected servers
6653 if needed. Normal server will send JOIN notify to its local client
6654 on same channel when received this packet. Added also corresponding
6655 sending function silc_server_send_new_channel_user to sent the
6658 * Added boolean route argument to send_notif_to_channel and
6659 packet_send_to_channel functions to attempt to route the packet
6660 if it is TRUE and send only locally if it is FALSE.
6662 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6664 * silc_server_replace_id now broadcasts the received replace ID
6665 packet if it is not broadcast packet already. The router must
6666 broadcast to inform other routers about changed ID.
6668 * Added backpointer to server's router into SilcServer context in
6669 silcd/server_internal.h.
6671 * Fixed silc_server_packet_broadcast to send correct broadcast
6674 * The channel key is now distributed to the local client as soon
6675 as it is received from the router (in router environment) so that
6676 no other packet may be sent for the channel until client has
6679 * silc_server_remove_channel_user now broadcasts the received
6680 Remove Channel User packet if it is not broadcast packet already.
6681 The router must broadcast to inform other routers about removed
6684 * Added users field into SilcPacketContext that is a reference count
6685 of the context. One can increase the reference count by calling
6686 silc_packet_context_dup which is now changed to just increase the
6687 reference count instead of duplicating the data. The reference
6688 count is decresed by calling silc_packet_context_free that will
6689 free the data after the reference count hits zero.
6691 For now on the packet context and everything allocated into it
6692 (including the raw packet from network) must be freed by calling
6693 the new silc_packet_context_free function. Added also new function
6694 silc_packet_context_alloc that must be used now to allocate the
6695 context. This also means that if a routine is asynchronous from
6696 silc_[client/server]_packet_parse_type the packet context must
6697 be duplicated by calling silc_packet_context_dup. Otherwise it
6698 gets free'd after silc_[client/server]_packet_parse_type returns.
6699 Also, one must remember that if packet is duplicated then its
6700 reference count must be decresed by calling the free function as
6701 many times as it was duplicated.
6703 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6704 from both client and server.
6706 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6708 * Made joining to a channel working in router environment.
6710 * Cleaned up JOIN command on server side and create function
6711 silc_server_command_join_channel internal routine to make the
6714 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6716 * Changed silc_command_pending list to SilcDList. Also, added
6717 `ident' field to SilcServerCommandPending structure to identify
6718 the reply and to call correct callback.
6720 Added silc_server_command_pending_check function to replace the
6721 corresnponding macro. The silc_command_pending list is not
6724 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6725 to set identifier to previously allocated Command Payload. It
6726 is used to set identifier for command when resending Command
6729 * Added silc_command_payload_encode_payload to encode Command
6730 Payload buffer from SilcCommandPayload structure.
6732 * Added silc_argument_payload_encode_payload to encode Argument
6733 payload buffer from SilcArgumentPayload structure.
6735 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6737 * Changed WHOIS command to support router connection on server side.
6738 The whois request is always sent to router unless the server is
6739 standalone server. After server has received the reply from the
6740 router will it send the reply to the client.
6742 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6743 broadcast received broadcast packet. The function is used only
6744 by router. The broadcast packet is always sent to the router's
6747 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6748 render given ID to printable string, for log files for example.
6750 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6752 * Made basic router to router connections working. At least they
6753 can now connect to each other but nothing really works the way
6754 they are supposed - yet.
6756 * Added new initiator token to RouterConnection configuration
6757 file in silcd/serverconfig.[ch]. It is used to tell whether we
6758 are the initiator to the remote router or whether we'll expect
6759 the other end to connect.
6761 * Moved registering of listener task to silc_server_init, hence
6762 the server starts listenning as soon as it is run, even if it
6763 does not have connections to other routers. Let's see how well
6766 * Changed default connection retry timeouts for more suitable in
6769 * Removed cipher and such arguments from silc_idlist_add_client
6770 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6771 Added new function silc_idlist_add_data to add the keys and stuff
6774 * Added SilcIDListData structure and added it to SilcClientEntry
6775 and SilcServerEntry as their first field in the structure. This
6776 way we can explicitly cast the ID entries to the SilcIDListData
6777 structure and get common data for the entries. In past, we had
6778 to first check what type of connection it is and then cast it to
6779 correct ID entry type. Now, we can directly cast the opaque
6780 pointer to the SilcIDListData (no matter what ID entry it actually
6781 is) and get the data needed.
6783 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6785 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6786 in some circumstances even if threre were timeout tasks, though not
6787 IO tasks, but tasks anyway. Now fixed.
6789 * Defined SilcServerConnection structure to hold connection specific
6790 stuff about directly connected servers and routers. The definition
6791 is currently in silcd/server_internal.h. I thought about having
6792 a bit more important role fro this struct but for now it is used
6793 only when connecting to other server (or router actually).
6795 * Added connecting retry support in server when connecting to
6796 router(s). The retry feature implement exponential backoff
6797 algorithm. Also, added SilcServerParams structure to hold default
6798 parameters for server. For now, it include these retry settings
6799 and are hard coded. After server is moded to be as Silc Server
6800 Library this structure will be more important.
6802 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6804 * Changed client librarys channel->clients table to SilcList and
6805 changed code accordingly.
6807 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6809 * Changed client's channel table to SilcList and changed code
6810 accordingly. Also changed SilcChannelClientEntry to include back-
6811 pointer to the channel so that client entry can use that structure
6812 as list as well and we have fast cross-reference to the channel.
6813 This change dramatically decreased the complexity of channel
6814 handling with client entry and vice versa (removed one extra
6815 loop when searching for channel entry from many functions).
6817 * Changed server->sim from table to SilcDList and changed code
6820 * NAMES command can now be used from user interface. It will show
6821 the user list on the channel, neatly.
6823 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6824 Code now saves realname of the user if it becomes available.
6826 * Renamed configure.in to configure.in.pre and made ./prepare
6827 script to automatically add correct version string to
6828 configure.in which it creates from configure.in.pre.
6830 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * NAMES command reply now shows users mode with the nickname when
6835 * Moved silc_client_ch[u]mode[_char] functions from
6836 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6837 place sucks, they are utility functions and should be in some
6840 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6842 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6845 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6849 * Added TRQ (efficient deque and list library) into lib/trq. This is
6850 a very good list library that is currently used in the SILC. Defined
6851 SilcList API over the library because I didn't like the API very
6852 much. See lib/trq/silclist.h for the API and examples of how to
6853 use the API. Fixed various places in the code to use the new
6854 SilcList API. The SilcList is meant for lists that has a structure
6855 already defined as a list. It is not suitable to add just some
6856 context to the list (in TRQ, the context is the list actually).
6858 So, I defined SilcDList that can be used for the purpose where
6859 predefined list structure does not exit. This can be used as
6860 such list. Now some context just can be added to the SilcDList.
6861 Currently this list is not used in the SILC just yet, though there
6862 are a lot places where this can replace dynamically allocated
6863 tables and I will fix these places, later, to use SilcDList.
6864 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6865 and use TRQ internally).
6867 Also fixed some annoying warning messages that the original TRQ
6868 code generated. Also minor changes to TRQ's Makefile.in.
6870 * Added support for querying by Client ID to both WHOIS and
6871 IDENTIFY commands into server, as required by the protocol.
6873 * Removed method function pointers from SilcBuffer structure. They
6874 weren't used to anything and just increased the context size for
6875 no good reason. This change also made silc_buffer_alloc and
6876 silc_buffer_free functions inline functions.
6878 * Disabled command flooding detection support until it's fixed so
6879 that it accepts commands in but does not execute them more than once
6882 * Added silc_net_localhost(), to return local hostname, into
6883 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6884 that must be initialized before calling silc_client_init.
6886 * Added new function: silc_server_send_notify_on_channels to send
6887 notify messages to all channels client has joined. It is assured
6888 that the message is sent only once per client.
6890 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6891 lib/silcutil/silcutil.[ch] as silc_format function. The new
6892 function is generic and is used by server as well, not only by
6893 the logging routines.
6895 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6896 the provided version string was not acceptable. Added new function:
6897 silc_ske_check_version into lib/silcske/silcske.h. The function
6898 must be implemented by the application (client or server) and it
6899 does not reside in the SKE library. The function checks the version
6900 string remote end sent.
6902 * Added back pointers (to opaque context and to SilcSocketConnection)
6903 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6905 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6906 duplicate packet context structure.
6908 * Changed `notify' client operation to send same arguments as client
6909 receives from server except for ID's. ID's are mapped to correct
6910 ID entry and that is returned. Also, if channel entry is not sent
6911 by server but the notify is for channel the channel entry is sent
6912 to application (otherwise application doesn't know that it is for
6913 channel (library gets it from packet's Destination ID)).
6915 * Added silc_client_remove_from_channels into client library to
6916 remove a client from all channels it has joined to. Used when
6917 received SIGNOFF notify from server. Added also new function
6918 silc_client_replace_from_channels to replace old ID entry with
6919 new ID entry on all channels. Used when received NICK_CHANGE
6922 * Fixed ID Cache list handling in silc_idlist_get_client in
6923 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6924 to get (or query) client by ID.
6926 * Updated TODO list.
6928 * Added connection authentication status message defined by the
6929 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6930 support for these into the code in client and server side.
6932 * Added generic function silc_client_send_command to send any command
6933 with variable argument list. Application should use this function
6934 to send commands if the command functions provided by the library
6935 does not suite for the application's user interface needs.
6937 * Added new `failure' client operation. Application is notified about
6938 received failure packet if client is executing a protocol. In this
6939 case the protocol's execution has failed.
6941 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6942 is required by the protocol.
6944 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6945 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6948 * Added status flag to SilcSKE object to indicate realtime status
6949 of the SKE protocol.
6951 * Application receives now exactly same command reply arguments as
6952 the library receives from server. However, if ID is received the
6953 corresponding ID entry is returned to the application (eg. Client
6954 ID is mapped to correct SilcClientEntry entry and that is returned).
6955 Changed command_reply client operation due to this change.
6957 * Changed all ID's in commands and in command replys as ID Payloads.
6958 Change affected both client and server side codes.
6960 All ID's sent in SILC network (with execption of ID's in SILC
6961 Packet header) are sent in ID Payload to support variable length
6964 * Server now notifies nick changes and notifies all clients on
6965 the channels about the new nickname (about the new Client ID,
6968 * Implemented CMODE command to change channel modes. Supports all
6969 channel modes defined by the protocol specs except ban and invite
6970 lists. (Also, private channel key mode is supported but support for
6971 setting private channel key in client is missing, thus, this mode
6972 has no effect on client side (except that server requires that the
6973 client uses private channel key and normal channel traffic does not
6976 Also, invite mode works per se, but INVITE command does not work
6977 yet correctly, so you can set channel as invite only channel but
6978 inviting clients to the channel does not work (it is yet to be
6979 thought what's the best way to do it).
6981 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6982 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6983 Implemented CUMODE command to change user's mode on the channel.
6984 Supports all modes defined by the protocol specs.
6986 * Added NAMES command reply to return users modes on the channel.
6988 * Removed unnecessary and slow ciphers from lib/silccrypt.
6990 * Set SO_KEEPALIVE option to connection sockets by default.
6992 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6994 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6995 redefined the Notify Payload into protocol specs.
6997 * Added silc_id_payload_parse_id to get ID directly from raw
7000 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7002 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7003 accept searching by Client ID as well.
7005 * Added support for LEAVE and SIGNOFF notify types in client library.
7007 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7008 to parse ID Payload from raw data.
7010 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7012 * Added flags parameter into silc_ske_assemble_security_properties
7013 function in lib/silcske/silcske.[ch].
7015 * Changed notify client operation to fit better for notify messages
7016 sent by server. The notify payload received from server is now
7017 passed to the application (after parsing it to SilcNotifyPayload).
7018 It is application's responsibility to retrieve the arguments
7019 from the payload and show the message the way it wants. The message
7020 sent by server is implementation specific.
7022 * Changed public keys to comply with the protocol specification.
7023 Old public keys are not supported anymore and are not compatible.
7025 * Removed nickname from Channel Payload as the latest draft removed
7026 it. The client must resolve the nickname from the NAMES command
7027 reply received when it joined the channel.
7029 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7031 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7033 * Fixed some errors in protocol specification drafts.
7035 * Created lib/silccore/silcnotify.c to implement Notify Payload
7036 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7037 generic payloads described by protocol specifications. The file
7038 includes implementations for ID Payload and Argument Payload.
7040 * Changed Command Payload implementation to use the new Argument
7041 Payload. Changed command_xxxx_payload to command_payload_xxxx
7042 to comply with SILC coding conventions.
7044 * Added suppport for Argument Payload handling in Notify Payload
7045 implementation as protocol requires it. Added the new support
7046 into server and client lib as well.
7048 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7050 * Added support for multiple nicknames on same channel. [n] is
7051 added locally to the nickname if there are more than one same
7052 nicknames on the channel.
7054 * Server now sends all nicknames that matched WHOIS request.
7055 Client also shows the list received from server.
7057 * Added TOPIC command to client side. User can now set and show
7058 current topic on channel.
7060 * Added MOTD command to client and server. Also, server sends the
7061 motd when client connects to the server.
7063 * Changed version strings to comply ISO 8601.
7065 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7067 * Fixed protocol error handling in client library. It should now
7068 cope even if the SKE fails for some reason.
7070 * Made new protocol specification drafts for submitting to IETF.
7072 * Implemented TOPIC command to server in silcd/command.c.
7074 * Added two new notify types into lib/silccore/silcnotify.h:
7075 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7076 notify nickname change and topic setting/change on a channel.
7078 * API change of command_reply operation in client library. The
7079 application gets now the status type received from server as well.
7081 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7083 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7085 * Cras fixed and optimized the packet handling even further and
7086 it should work now. Minor change to the prototype of function
7087 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7089 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7091 * Added new function into lib/silcutil/silcschedule.[ch]:
7092 silc_schedule_with_fd to select() a specified fd. The function
7093 returns after timeout expires or data arrives or goes. The
7094 function is used by packet routines to wait that all data is
7095 received from network.
7097 * Fixed data reading from network in lib/silccore/silcpacket.c.
7098 The code now assures that all data is read from the fd and then
7099 continues packet processing. This was a bug fix since the code
7100 used to drop some data in some circumstances.
7102 * Added new function into lib/silcclient/client.[ch]:
7103 silc_client_start_key_exchange to start key exchange after
7104 connection has been established to server. The code internally
7105 now uses this funtion but its main purpose was to provide it
7106 for applications that perform their own connecting. After
7107 application has created a connection it merely calls this
7108 function to start the key exchange between client and server.
7109 The library takes care of everything else after that.
7111 Updated also lib/silcclient/README to explain the usage of
7114 * Do not send to application information that connection has
7115 been established. Application gets notified it by connect
7118 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7120 * Applied cras's patch to add silc_schedule_one function. The
7121 function runs scheduler once and returns.
7123 * Fixed the scheduler after cras messed it up. The timeout
7124 handling works now as it's supposed to work.
7126 * Added into lib/silccore/ silcnotify.h to include notify
7127 message types support. Changed silc_server_send_notify*
7128 functions, in server.[ch], to support those new notify types.
7129 Added the support for the notify types into client library,
7130 as well. Added new notify client operation into ops.h in
7133 * Changed silc_server_packet_send_to_channel to send normal
7134 packets instead of just channel message packets. The function
7135 is now used to send the notify packets to channels. It is not
7136 used to send channel message packets anymore, as server never
7139 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7140 va_arg()s as it seems to require it nowadays. I guess, if SILC
7141 is compiled with older va_arg() the new code should work anyway.
7143 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7145 * Splitted core library. Core library (lib/silccore) includes
7146 now only SILC protocol specific core (and common) components.
7147 Created new utility library (lib/silcutil) that includes more
7148 generic purpose stuff. The stuff for util library was taken
7149 from the old core library. This was minor and easy split.
7151 * Created SILC Client Library (lib/silcclient) that includes
7152 implementation of the SILC client without user interface. This
7153 was major move from silc/ directory. The code has been changed
7154 so that it is transparent towards the user interface. The
7155 silc/ directory includes now the same user interface as before
7156 and it uses the new client library. Read lib/silcclient/README.
7157 Basicly, the client library performs everything else related
7158 to SILC except user interface handling. Also, configuration
7159 files are considered to be part of user interface and library
7160 does not handle them.
7162 This change also changed a lot of structures, function naming etc.
7163 Most important change was that SilcClientWindow object was
7164 renamed to SilcClientConnection in the client library. Created
7165 also new file lib/silcclient/ops.h. Also added new files
7166 silc/local_command.[ch] and silc/client_ops.[ch].
7168 All these changes were made to make it easier for user interface
7169 designers to create what ever user interface for the SILC client
7172 It is also expected that the server will be moved to lib
7173 directory as well and SILC Server Library will be created;
7174 sometimes in the future.
7176 * Removed Local commands from lib/silccore/silccommand.h as
7177 they are application specific and new client library does not
7178 handle any of those anymore.
7180 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7181 old client implementation in silc/.
7183 * Added support for callback functions in SILC_LOG_* macros.
7184 Application can now set its own callbacks that will be called
7185 instead of using the default functions that will always print
7186 the debug messages to stderr (or stdout). Also, debugging can
7187 now be disabled by setting silc_debug to FALSE and re-enabled by
7188 setting it to TRUE. Note, that logging will still work even
7189 if debugging is disabled.
7191 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7192 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7193 silc_log_reset_debug_callbacks.
7195 * To enable debugging in silc client one must give now -d
7196 option on command line.
7198 * Changed silc_schedule_init to automatically allocate task queues
7199 if they are not allocated before calling it.
7201 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7203 * Added GMP 3.1 into math library.
7205 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7207 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7208 a channel in SILC network. The packet is used by servers and
7209 routers to notify other routers that user has left a channel.
7210 This little feature was missing until now. Added the feature
7211 to protocol specification as well.
7213 Added functions: silc_server_send_remove_channel_user and
7214 silc_server_remove_channel_user into server.[ch].
7216 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7217 lib/silccore/silcpacket.h. However, they are not implemented
7220 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7222 * Fixed joining to a channel and sending channel messages
7223 between server and router. The channel message sending should
7224 now work inside a cell.
7226 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Fixed the private message sending between server and router.
7229 The private message sending should now work inside a cell.
7231 * Added silc_server_replace_id into server.[ch] to replace
7232 existing ID in the SILC network.
7234 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7235 and silc_idlist_replace_server_id into idlist.[ch] in server.
7237 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7239 * Fixed the server to server connections. Server can again now
7240 connect to router. Router to router connections probably does
7243 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7245 * Added dynamic protocol registering support. Now protocols can
7246 registered and unregistered on the fly. Patch by cras.
7248 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7250 * Added lib/contrib directory to hold routines that some platforms
7251 don't have but are needed by SILC.
7253 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7254 into lin/contrib to provide getopt() and getopt_long() for
7255 those who don't have it.
7257 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7259 * Added AWAY command to client. When away message is set and
7260 client receives a private message packet the client automatically
7261 replies to the sender with the away message.
7263 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7264 bug seemed to be the cause of recent problems when compiling
7267 * Added version detection support to SKE protocol specification
7268 and added the new changes to the SKE implementation as well.
7269 There were other minor changes in the SKE protocol as well.
7271 Many changes in lib/silcske/silcske.[ch] and in
7272 lib/silcske/payload.[ch].
7274 * Added ^U functionality, clear input line. Patch from cras.
7276 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7278 * Mainly small bugfixes on core library. Fixed some debugging
7279 logging and buffer overflow in silclog.c.
7281 * Updated config.sub and config.guess on the distribution tree.
7283 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7285 * Added command lagging support in server. Client may execute
7286 commands now only once in two seconds.
7288 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7290 * Optimized packet reception. MAC computation and checking is now
7291 also more optimized. A lot previously duplicated code is now
7292 used as generic by both client and server.
7294 * Fixed key pair generation in clientutil.c
7296 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7298 * Added into lib/silccore/silcbufutil.[ch] new function;
7299 silc_buffer_realloc.
7301 * Moved generic packet sending/encryption functions to
7302 lib/silccore/silcpacket.[ch] from client and server. Some
7303 rewriting of the functions.
7305 * Moved all generic packet reception/decryption functions to
7306 lib/silccore/silcpacket.[ch] from client and server. The
7307 packet processing is now much cleaner in both client and server.
7308 These were major changes in both client and server.
7310 * Created many common functions in server to do packet sending.
7311 Previously code were duplicated a lot, this has been removed
7314 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7316 * Rewrote major parts of the ID cache system. Don't know
7317 whether it is better now or not but at least the API is more
7320 * Major rewrite on ID cache stuff on client because of the ID
7321 cache API changes. Added idlist.c to client.
7323 * Also major rewrite on ID cache stuff on server as well.
7324 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7325 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7326 in hand, instead they are all put into the ID cache system now.
7327 All server_idlist_* routines uses ID cache now instead of
7328 traversing its own lists (those lists does not exist anymore).
7329 SilcIDList though still exists. Also, SilcXXXEntry's are
7332 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7334 * Finally made the SKE implementation compliant to the protocol
7335 specification. All mp integers are now binary encoded as
7336 opposed being HEX encoded.
7338 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7341 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7342 functions: silc_[encode/decode]_pem. Also added function
7343 silc_encode_pem_file to PEM encode with newlines ('\n') for
7346 * SILC public keys are now encoded either PEM or binary. Same
7347 option is for private keys as well. By default private keys
7348 are binary encoded and public keys PEM encoded. Silly HEX
7349 encoding were removed.
7351 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7352 function to create fingerprints.
7354 * Fixed a bug in SHA1; does not change the original data anymore.
7356 * Partly implemented INFO command on client and server side.
7357 Fixed CLEAR command. Changes to SERVER command; show current
7358 server(s) when giving command without arguments. Added
7359 VERSION command to client.
7361 * Added check to server that unregistered connections cannot
7362 execute commands (unless it is specificly allowed).
7364 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7366 * Fixed screen refresh.
7368 * Fixed channel joining bug from client. On some circumstances
7369 client tried to join to a channel it had already joined.
7371 * Added public key verification process into client's protocol.c.
7372 The client now verifies the public key from user and saves
7373 it into ~./silc/serverkeys/ directory.
7375 Added into: clientutil.[ch]: silc_client_verify_server_key.
7377 * Changed SKE protocol's silc_ske_initiator_finish function
7378 to accept callback function that verifies the received public
7379 key. Removed old silc_ske_verify_public_key function.
7381 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7383 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7384 silc_pkcs_private_key[_data]_set.
7386 * Made the password and public authentication more cleaner in
7387 server's protocol.c.
7389 * Removed historic and obsolete protocol `channel_auth' from
7390 both client and server.
7392 * Removed wrong way of sending command status messages from
7393 server to client in server's command.c. The old way violated
7394 protocol specification.
7396 Changes to silccore/silccommand.[ch]: removed
7397 silc_command_encode_status_payload -> not needed anymore,
7398 changed silc_command_encode_payload_va to accept extra
7399 argument on variable argument list. The argument type must
7400 now be provided to the function. Also, added new function:
7401 silc_command_encode_reply_payload_va which is same as
7402 normal command_encode_payload_va except command status type
7403 is provided as extra argument.
7405 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7407 * Added ~./silc directory handling. The directory includes the
7408 public and private keys for the client.
7410 Added silc_client_check_silc_dir, silc_client_create_identifier
7411 and silc_client_load_keys.
7413 * Implemented SILC protocol compliant public key. Added public
7414 and private key saving to and loading from files.
7416 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7417 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7418 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7419 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7420 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7422 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7423 silc_pkcs_load_[public/private]_key.
7425 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7427 * Added silc_server_get_route (route.[ch]) to get connection
7428 data for the fastest route for given ID.
7430 * Implemented INVITE command on client and server. The command
7431 were re-defined in the SILC Protocol Specification and the
7432 implementation now complies with the specification.
7434 * Implemented PING command on client and server.
7436 * Implemented NAMES command on client and server. The server side
7437 supports currently only normal server not router server yet.
7438 Some changes to NAMES definition in SILC protocol specification.
7440 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7442 * Implemented LEAVE command on client and server.
7444 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7445 again. This change was made to the protocol as well. Server
7446 should not violate the protocol specification anymore.
7448 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7450 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7451 was tested. SOCKS4 was not but should work anyway.
