1 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added macro SILC_PACKET_DATALEN which can be used during
4 packet assembling to check whether the data to be added to
5 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
6 len is truncated until it fits it.
8 Added checks for maximum length of channel message payload and
9 private message payload also.
11 Added checks for maximum packet length in server and in
14 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
15 lib/silcclient/client.c, lib/silccore/silcchannel.c and
16 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
17 lib/silcclient/client_prvmsg.c.
19 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
21 * Added silc_server_packet_queue_purge call to the
22 silc_server_disconnect_remote to assure that all data in the
23 queue before disconnecting is sent to the network. Affected
26 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
28 * Added the deleting of server's own ID cache entry to the
29 silc_server_free function. Free also everything else that
30 has been allocated in silc_server_init. The affected file
33 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
35 * Added functions silc_parse_version_string, silc_version_to_num,
36 and silc_ske_parse_version to parse SILC protocol style version
37 strings. Affected files lib/silcutil/silcutil.[ch] and
38 lib/silcske/silcske.[ch].
40 * Added new configuration params: version_protocol, version_software
41 and version_software_vendor to specify what version the remote
42 host must at least be to be able to connect to server. The vendor
43 string can be regex matched too. Added new function
44 silc_server_connection_allowed to check maximum number of allowed
45 connections, and allowed versions for incoming connections.
46 Affected files are silcd/server.c, server_util.[ch] and
49 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
51 * Added preliminary support for signals in scheduler. The
52 signals we care about are now blocked always when the scheduler
53 is locked. This way we can synchronise the use of signal with
54 scheduler. It is guaranteed that when signal occurs the scheduler
55 is not locked, and thus new tasks can be safely added to the
58 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
59 to silc_schedule_internal_init and silc_schedule_internal_uninit.
60 Added new platform specific routines
61 silc_schedule_internal_signals_[un]block and
62 silc_schedule_internal_signal_[un]register.
64 Added new functions to SILC Schedule API:
65 silc_schedule_signal_[un]register. Each signal that application
66 is going to use should be registered to the scheduler.
68 Affected files are lib/silcutil/silcschedule.[ch],
69 lib/silcutil/*/silc*schedule.c.
71 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
73 * Check for unauthenticated client and server in the
74 silc_server_new_client and silc_server_new_server functions.
75 Affected file silcd/packet_receive.c.
77 * Added function silc_string_is_ascii to check whether given
78 string is 7-bit ASCII string. Affected files are
79 lib/silcutil/silcutil.[ch].
81 * Added function silc_id_is_valid_server_id into the
82 silcd/serverid.c and added checking for valid Server ID's in
83 silc_server_new_server. The Server ID must always be based
84 on the server's public IP address.
86 * Added logging of DISCONNECT packet message in the server.
87 Affected file silcd/server.c.
89 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
91 * Changed all library interfaces that use Global RNG to also
92 accept SilcRng as argument. Affected files are
93 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
94 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
95 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
96 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
99 * Added function silc_pkcs_generate_key to the
100 lib/silccrypt/silcpkcs.[ch] for applications so that they
101 don't need to do pkcs->pkcs->init calls anymore.
103 * Remove SilcSocketConnection from the SFTP API since it really
104 wasn't needed there. The application has the information
105 saved in its contexts anyway and the SFTP layer doesn't need
106 know about it. Affected files lib/silcsft/silcsftp.h and
107 lib/silcsftp/sftp_[server/client].c.
109 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
110 The SilcSimContext is not SilcSim.
112 * Fixed possible buffer overflows in silc_id_render in the
113 lib/silcutil/silcutil.c.
115 * On EPOC the global crypto module lists are not used at all
116 in the crypto library. Added support for using the constant
117 algorithm list on EPOC. Affected files are
118 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
121 * Fixed the handling of third parameter of KICKED notify, since
122 it was mistakenly updated to SILC Protocol 1.0 even though it
123 is to be included in 1.1. Since it is not in 1.0 it is not
124 mandatory, and this fix now handles it only if it is provided,
125 and it is not error if it is not provided. Affected file
126 lib/silcclient/client_notify.c.
128 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
130 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
131 client. Affected file irssi/src/silc/core/client_ops.c.
133 * Merged with Irssi 0.8.4 from irssi.org CVS.
135 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
137 * Check for valid socket connection in client entries before
138 sending any messages. Fixes a crash, but doesn't fix some
139 other underlaying bug that is lurking there. Affected
140 file silcd/packet_send.c.
142 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
144 * $usermode, $cumode and $cumode_space expandos shouldn't do
145 anything with non-SILC server records. Affected file
146 irssi/src/silc/core/silc-expandos.c
148 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
150 * Fixed the silc_net_check_[host/local]_by_sock to support
151 IPv6 bound sockets as well. Now they can return IPv6 addresses
152 as well. Affected file lib/silcutil/silcnet.c.
154 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
155 Affected lib/silcutil/unix/silcunixnet.c.
157 * Fixed ID rendering (at least on some platforms, not NetBSD)
158 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
160 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
162 * Added silc_hash_public_key and silc_hash_public_key_compare
163 functions to be used with SilcHashTable. They can be used to
164 hash public keys and compare public keys in hash table. Affected
165 file lib/silcutil/silcutil.[ch].
167 * Added support for specifying multiple public keys for Client
168 connection section in server configuration file. This makes it
169 possible to accept multiple public keys from same host, or to
170 make a section that accepts any incoming host, and have the
171 accepted public keys listed in the section.
173 Added functions silc_sever_[find/get]_public_key, added the
174 support for this actually to all connection sections but only
175 the Client section is currently allowed to specify multiple
178 Affected files are silcd/server.c, server_internal.h,
179 command.c, protocol.c, server_util.[ch], packet_receive.c.
181 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

185 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
187 * If silc_debug is TRUE, also output standard logging messages
188 to stderr with the debug output.
190 Made silc_log_reset_all() flushing all channels before returning.
191 Also fixed some documentation typos.
193 Affected files are lib/silcutil/silclog.[ch].
195 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
197 * Fixed the server to check correctly the amount of connections
198 from single host, by checking also the type of the connection.
199 Fixed also the comparison of number of connections and number
200 of allowed connections. Affected files are silcd/server.c,
203 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
205 * Fixed the USERS command reply to save the user's mode on the
206 channel as well. Fixed JOIN command reply to check whether a
207 client is on channel already and not join it twice. Affected
208 file lib/silcclient/command_reply.c.
210 * Added new file silc-expandos.c into irssi/silc/core/ to return
211 various stuff for various signal for the statusbar etc. updating.
212 Now Irssi SILC client prints channel user modes etc. on the
215 * The user mode (like server/router operator changes) is now shown
216 on the Irssi SILC client's statusbar. The affected files are
217 irssi/src/silc/core/client_ops.c, silc-expandos.c.
219 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>

222 to SILC_SCHEDULE_[UN]LOCK macros.
224 * Added more error printing to logs in server code. Affected
225 files silcd/server.c and silcd/protocol.c.
227 * Fixed -S option parsing in Irssi SILC Client. Affected file
228 irssi/src/silc/core/silc-core.c.
230 * Added silc_buffer_alloc_size function. Affected file is
231 lib/silcutil/silcbuffer.h.
233 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
235 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
236 constants. Affected files in
237 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and

246 check the size of 64 bits types with sizeof(). Affected
247 file is lib/silcutil/silcbuffmt.c.
249 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
251 * Removed 0.6.x backwards support.
253 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
255 * Changed all integer type names:
256 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
257 to avoid collisions with other libraries using same type names
260 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
262 * Added `prefer_ipv6' argument to the functions
263 silc_net_gethostbyname[_async]. If it is TRUE it will return
264 IPv6 address over IPv4. If FALSE IPv4 address is returned
265 even if IPv6 address was found. Affected files
266 lib/silcutil/silcnet.[ch].
268 * Added support silc_net_create_connection[_async] to fallback
269 to IPv4 address if IPv6 address could not be used (like if

282 application does not need to define them. Affected file
283 includes/silcincludes.h.
285 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
286 old name went against naming convention. Applications now
287 include "silcclient.h" instead of "clientlibincludes.h".
288 Removed includes/clientlibincludes.h, it is redundant now.
290 * Renamed includes/version.h to silcversion.h.
292 * Added really preliminary support for OS/2 into the util
293 library. Only thread & mutex API is implemented, others
294 are still to be implemented. Created the lib/silcutil/os2/
295 directory. Created also file includes/silcos2.h.
297 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
299 * Added preliminary BeOS support into the util library.
300 Created lib/silcutil/beos/, and implemented all the needed

324 to the lib/silcutil/silcbuffer.h.
326 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
328 * Added `user_count' to the SilcChannelEntry which now tells the
329 number of users on the channel. The user count is now saved
330 in normal server of global channels as well. Affected files
331 silcd/server.c, idlist.h, packet_receive.c and command.c.
333 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
334 include file utility functions.
336 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
337 instead of calling directly OS routines.

344 client_entry->channels hash table everytime nick is changed.
345 Affected file lib/silcclient/client.c.
347 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
349 * ROBOdoc documented the lib/silcske/silcske.h, and improved
350 the SKE interface a bit.
352 * Fixed padding problem in PKCS#1. The padding was not actually
353 random since the random number generator was used incorrectly.
354 This security bug affects only when encrypting with PKCS#1, and
355 it is not currently used at all in SILC. SILC only use signing
356 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
358 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

416 is now done in silc_core_init() which also fixes autoconnecting
419 Affected files irssi/src/silc/core/silc-core.c,
420 irssi/src/fe-text/silc.c.
422 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
424 * Added new configuration options and blocks:
425 keepalive_secs, reconnect_count, reconnect_interval,
426 reconnect_interval_max, reconnect_keep_trying and
427 require_reverser_lookup. Added ConnectionParam block, and
428 implemented the connection parameters when connecting as
429 initiator and when accepting connections as responder.
431 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
432 whether given configuration value has been given already.
434 Affected files silcd/serverconfig.[c], server.[c].
436 * Splitted the doc/example_silcd.conf.in. Separated the crypto
437 algorithm parts and created new file silcalgs.conf, that
438 is now included from the example_silcd.conf.in.
440 * Optimized the silc_server_connect_to_router_second to take
441 the connection configuration object from the SilcServerConnection
442 object instead of finding it during the connecting phase.
443 Added the configuration object to SilcServerConnection struct.
444 Affected files silcd/server_internal.h, server.c.
446 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
448 * Add the client on channel after it was resolved at the
449 channel message receiving, and it was not already on the
450 channel. Affected file lib/silcclient/client_channel.c.
452 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
454 * Fixed the public key authentication to allocate always the
455 destination signature buffer instead of using static buffer.
456 Affected file silcd/protocol.c.
458 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
460 * Unified the serverconfig.[ch]'s helper function interface.
461 Affected file silcd/serverconfig.[ch].
463 * Removed doc/example_silc.conf.in since it is redundant.
464 The make install will now install irssi/silc.conf file.
466 * Added new Passphrase and Publickey authentication methods to
467 config file, allowing both public key and passphrase based
468 authentication to be set at the same time.
470 Added `prefer_passphrase_auth' setting in config file which
471 can be used to set to prefer passwd auth if both passwd and
472 public key is set. If not set, public key is preferred.
473 This has effect only when being initiator (responder will try
476 Added support for authentication with passphrase and public key
477 at the same time. The passphrase is tried first always since
478 it is faster to check.
480 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
482 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

529 zero port also if the hostname is NULL because it could not
532 Call file transfer monitor callback now also if error occurs
533 during key agreement protocol.
535 Changed the silc_client_file_send interface to return the
536 SilcClientFileError instead of session id. The session ID
537 is returned into pointer provided as argument.
539 Check that the file exists locally before sending the
540 file transfer request at all.
542 Affected file lib/silcclient/client_ftp.c, silcapi.h.
544 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

548 * Fixed the event_mode CMODE handler to not crash when mode
549 is changed and +k mode is set in the channel. Affected file
550 irssi/src/silc/core/silc-channels.c.
552 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
553 SILC_LOG_WARNING to give out Warning and not Error. Affected
554 file lib/silcutil/silclog.c.
556 * Fixed the channel message payload decryption in the function
557 silc_channel_message_payload_decrypt to not modify the original
558 buffer before it is verified that the message decrypted
559 correctly. Otherwise, next time it is called with correct
560 channel key it won't encrypt since the payload is corrupted.
561 Affected file lib/silccore/silcchannel.c.
563 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
565 * Do not constantly resize the window. A fix patch by cras.
566 Affected file irssi/src/fe-text/screen.c.
568 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
570 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
571 Affected file lib/silcutil/silcnet.c.
573 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
575 * Fixed a bug in hash table internal routine for traversing
576 the table with foreach callback. The current entry may
577 become invalid in the callback but it was referenced after
578 the callback returned.
580 Do not allow auto rehashing of hash table during the
581 silc_hash_table_foreach operation, for same reasons as it is
582 not allowed for SilcHashTableList. Affected files are
583 lib/silcutil/silchashtable.[ch].
585 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
587 * Defined DLLAPI into silcincludes.h and silcwin32.h for
588 Win32 DLL. extern's in header files are now declared with
591 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
593 * Fixed private message handling. It used some old code that
594 caused the client to crash. Affecte file is
595 lib/silcclient/client_prvmsg.c.
597 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
599 * Added function silc_client_add_channel,
600 silc_client_replace_channel_id, and removed functions
601 silc_client_new_channel_id and silc_idlist_get_channel_by_id
604 * Added cross reference of the joined channels to the
605 SilcClientEntry, and changed the SilcChannelEntry's
606 users list to SilcHashTable. The affected files are
607 lib/silcclient/idlist.[ch].
609 * Fixed a bug in hash table tarversing. While the hash table
610 is traversed with SilcHashTableList the table must not be
611 rehashed. It is now guaranteed that auto rehashable tables
612 are not rehashed while tarversing the list. Also defined that
613 silc_hash_table_rehash must not be called while tarversing
614 the table. Added function silc_hash_table_list_reset that must
615 be called after the tarversing is over. The affected files are
616 lib/silcutil/silchashtable.[ch].
618 * Changed all hash table traversing to call the new
619 silc_hash_table_list_reset in server and in client library.
621 * Added function silc_client_on_channel to return the
622 SilcChannelUser entry if the specified client entry is joined
623 on the specified channel. This is exported to application as
624 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
626 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
628 * Fixed founder regaining problem with JOIN command on normal
629 server. The notify for mode change must be sent always and
630 not only if !cmd->pending. Affected file silcd/command.c.
632 * Fixed the WHOWAS command's reply sending to support the
633 lists correctly. Affected file silcd/command.c.
635 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
637 * When sending JOIN command to router for processing the
638 sender's old command identifier was not saved back to the
639 sender's command context, fixed now. The affected file is
642 * Create the key in JOIN command of the router did not return
643 the channel key, added check for this. Affected file is
646 * Fixed a channel ID update bug in JOIN command reply. Do
647 not directly upgrade the ID but call the function
648 silc_idlist_replace_channel_id if the ID was changed.
649 Affected file silcd/command_reply.c.
651 * Fixed memory leaks from command calling if it would fail.
652 Affected file silcd/command.c.
654 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
656 * Applied patches from cras:
658 Memory leak fixes around libaries, irssi window resize fix,
659 new silclist.h and silcdlist.h, all extern inline changed to
662 * Removed dotconf from lib/dotconf, not needed anymore.
664 * Removed TRQ from lib/trq, not needed anymore.
666 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
667 with server connections. Later this will be configurable
668 in config file after new config file is done. Affected file
671 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
673 * Fixed a crash in server related to channel announcements.
674 Affected file silcd/server.c.
676 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
678 * Fixed memory leaks in silc_server_create_new_channel*
679 functions. Affected file silcd/server.c.
681 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
682 which ID was changed. This way the router will send the
683 user list for the channel again, and server won't be in
684 desync in some rare circumstances. Affected file is
685 silcd/packet_receive.c.
687 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
689 * Check for NULL socket pointer in the function
690 silc_server_packet_send_to_channel_real. Affected file
693 * Fixed the BAN notify handling to correctly remove ban
694 list. Affected file silcd/packet_receive.c.
696 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
698 * Fixed some header addition to Toolkit distribution in
699 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
701 * Added lib/silcclient/client_ops_example.h as an template
702 file for application programmers to quickly start using
703 the SilcClientOperation functions in their application.
704 Updated the lib/silcclient/README as well to tell about this
705 nice file made available.
707 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
709 * Call silc_server_remove_from_channels when removing client
710 entry when NO_SUCH_CLIENT_ID was received. Affected file
711 is silcd/command_reply.c.
713 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
715 * Added server & router operator statistics updating. Affected
716 file silcd/packet_receive.c and silcd/command.c.
718 * Fixed the SERVER_SIGNOFF notify handling on normal server
719 not to save the history information for clients. Same was
720 fixed earlier in remove_clients_by_server function, but not
721 here. Affected file silcd/packet_receive.c.
723 * Raised the default connection-retry count from 4 to 7 in
724 server. Affected file silcd/server.h.
726 * Cancel any possible reconnect timeouts when we start the
727 key exchange. Affected file silcd/server.c.
729 * Do not reconnect on connection failure when SCONNECT was
730 given. Affected files silcd/server.[ch].
732 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
734 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
736 * Fixed the NICK command to always give the unformatted
737 nickname to the one giving the NICK command. If unformatted
738 nickname is cached already it will be formatted and the
739 local entry will always get the unformatted nickname.
740 Affected file lib/silcclient/idlist.c.
742 * Fixed some double frees from client library commands.
743 Affected file is lib/silcclient/command.c.
745 * Fixed CUMODE command in server to assure that no one can
746 change founder's mode than the founder itself, there was a
747 little bug. Affected file silcd/command.c.
749 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
751 * Removed the SilcClientCommandDestructor from the client
752 libary, it is not needed anymore. Affected files are
753 lib/silcclient/silcapi.h, command[_reply].[ch],
754 client_notify, idlist.c.
756 * Fixed GETKEY command to first resolve client, and then
757 resolve the server only if the client was not found, instead
758 of resolving both at the same time. Affected file is
759 lib/silcclient/command.c.
761 * Added silc_client_start_key_exchange_cb and lookup the
762 remote hostname and IP address before starting the key
763 exchange with server. The affected file is
764 lib/silcclient/client.c.
766 * The server's public key is now saved using the IP address
767 of the server and not the servername for the filename.
768 The hostname public key filename is checked as an fall back
769 method if the IP address based filename is not found.
771 Fixed the GETKEY command to save the fetched server key
774 Print the remote server's hostname now when new key is
775 received during connection process. Affected file is
776 irssi/src/silc/core/client_ops.c.
778 * Return always our own public key to the client if it asks
779 for it with GETKEY command. Affected file silcd/command.c.
781 * Removed the use_auto_addr variable from default config
782 file since it was in wrong section. Affected file is
785 * Fixed TOPIC_CHANGE notification to not route it when it
786 was sent using silc_server_send_notify_to_channel function.
787 Affected file silcd/command.c.
789 * Fixed silc_server_send_notify_kicked to send the kicker's
790 Client ID also, it was missing. Affected files are
791 silcd/command.c, silcd/packet_send.[ch].
793 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
795 * Do not save client history information in SERVER_SIGNOFF.
796 Fixes the bug in normal server that it does not detect
797 the client becoming valid after the server becomes back
798 online. Affected file silcd/server_util.c.
800 * Added `sock_error' field into the SilcSocketConnection
801 context. When error occurs during socket operation (read
802 or write) the error is saved. Added also new function
803 silc_socket_get_error to return human readable socket error
804 message. Affected files are lib/silcutil/silcsockconn.[ch],
805 lib/silcutil/unix/silcunixsockconn.c, and
806 lib/silcutil/win32/silcwin32sockconn.c.
808 * The server now prints the socket error message in the
809 signoff for client. Affected file silcd/server.c.
811 * Fixed the `created' channel information sending from router
812 to server in JOIN command. Checks now whether the channel
813 really was created or not and set it according that.
815 Fixed the JOIN command to use the client entry's current
816 ID during the joining procedure instead of the one it sent
817 in the command (it is checked though), since it can change
818 between the packet processing and command processing, and
819 would just case unnecessary pain in the client end. Affected
820 file silcd/command.c.
822 * Fixed a channel key payload sending to use correct channel
823 ID when the server was forced to change the channel's ID by
824 router. Router sent the key payload with the old Channel ID.
825 Affected file silcd/packet_receive.c.
827 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
829 * Call silc_server_save_channel_key only if the key payload
830 was provided in the JOIN command's command reply. Affected
831 file silcd/command_reply.c.
833 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
835 * Fixed silc_mp_sizeinbase to return the value correctly with
836 MPI. Affected file lib/silcmath/mp_mpi.c.
838 * Fixed the stop_server signal to correctly stop the scheduler
839 and gracefully stop the server when SIGTERM or SIGINT signals
840 are received. Affected file silcd/silcd.c.
842 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
844 * Simple handling of TERM and HUP signals. Also added some log
845 flushing call around. Affected file is
848 * Fixed small bugs in silclog.c. Now buffering output will take
849 effect after 10 seconds since startup: This will ensure that
850 no important startup messages are lost. Also output redirection
851 will preserve original format ([Date] [Type] message).
852 Affected file is lib/silcutil/silclog.c.
854 * Added two options to the config file, in the logging section:
855 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
856 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
858 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
860 * Do not print the warning about log files not being initialized
861 more than once to avoid excess logging. Affected file is
862 lib/silcutil/silclog.c.
864 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
865 the SIM copying in make install in Makefile.am.pre.
867 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
869 * Rewritten silclog APIs. Globally interesting changes follows:
870 silc_log_set_files() changed to silc_log_set_file().
871 silc_log_set_callbacks() changed to silc_log_set_callback().
872 ROBOdoc documented silclog header file.
873 SilcLogCb now returns bool to wether inihibit the default
874 handler or not (to keep the old behaviour return always TRUE).
875 The new APIs should also fix the problem of the
876 silcd_error.log file that was written in the current directory.
879 Log files streams will remain opened after silc_log_set_file()
880 call, means less CPU usage notably on high traffic servers.
881 File streams are now full buffered, and flushed to the disk
882 every 5 minutes, lesses HD activity and CPU usage.
883 Messages can be redirected, allowing admins to configure
884 one single logfile for all server messages.
885 the silc_log_quick global variable to activate fast-logging.
886 Affected files lib/silcutil/silclog.[ch]
888 * Changed some code to conform new silclog APIs. Affected
889 files are doc/example_silcd.conf.in, silcd/server.c
890 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
893 * Fixed a memory leak that could occur in some situations.
894 Affected file silcd/serverconfig.c.
896 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
898 * Added the silc_client_del_client to remove the client from
899 all channels as well. Affected file lib/silcclient/idlist.c.
901 * Fixed the client library to correctly remove the client
902 from all channels when the client entry is being destroyed.
903 Affected file lib/silcclient/client_notify.c, command.c.
905 * Added auto-nicking support to the client library. If the
906 applicatio now sets client->nickname it will be sent to the
907 server after connecting by the library. This way for example
908 SILCNICK (or IRCNICK) environment variables will have effect
909 and always change the nickname automatically to whatever
910 it is wanted. Affected file lib/silcclient/client.[ch].
912 * Renamed silc_server_command_bad_chars to the
913 silc_server_name_bad_chars and moved it to the
914 silcd/server_util.[ch]. Added also new function
915 silc_server_name_modify_bad to return nickname that
916 includes bad characters as new nickname without those
917 bad characters. This check and modify is now used in
918 silc_server_new_client when the username is initially set
919 as nickname, so it must be checked to be valid nickname.
920 Affected file silcd/packet_receive.c.
922 * The nickname length is now taken from the packet for real
923 and not trusted to strlen() since it clearly can return
924 wrong length for nickname including bad characters. This
925 also applies to channel names. Affected file silcd/command.c.
927 * Removed the lib/silcsilm/modules directory. Modules are now
928 compiled into the lib/silcsim. Fixed the copying of the
929 modules to follow symbolic links in Makefile.am.pre.
931 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
933 * Fixed silc_string_regexify list creation. Fixes bugs with
934 BAN and INVITE commands in server. The affected file is
935 lib/silcutil/unix/silcunixutil.c.
937 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
939 * Removed the command destructor entirely from the server's
940 command and command reply routines. It is not needed, and
941 its usage was buggy and caused crashes. Affected files are
942 silcd/command[_reply].[ch].
944 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
946 * Cancel protocol and NULL sock->protocol if timeout
947 occurred during protocol. Affected file silcd/server.c.
949 * Cancel protocol timeouts always before calling the final
950 callback, to assure that after final callback is called
951 no other state will be called for the protocol anymore.
952 Affected file silcd/protocol.c.
954 * Print error log if incoming connection configuration could
955 not be found. Affected file silcd/server.c.
957 * Fixed JOIN command to correctly save the founder mode
958 to the client on normal SILC server, when the channel
959 was created by the router. Affected file silcd/command.c.
961 * Fixed LIST command (hopefully) to send correct reply
962 packets. Affected file silcd/command.c.
964 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
966 * The silc_packet_receive_process now returns FALSE if the
967 read data was invalid packet, and TRUE if it was ok.
969 The server now checks that if unauthenticated connection
970 sends data and its processing fails the server will close
971 the connection since it could be a malicious flooder.
973 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
975 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
977 * Make sure the warning about error opening a log file is
978 printed only once and not everytime it fails (produces
979 too much useless log). Affected file lib/silcutil/silclog.c.
981 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
983 * Made the silc_server_daemonise() function more readable.
984 Affected file silcd/server.c.
986 * Pid file is now optional, the user may comment it out from
987 the config file. Removed define SILC_SERVER_PID_FILE, we
988 don't need a default any longer. Affected file
989 configure.in.pre, lib/Makefile.am.pre.
991 * Make some use of the pid file. The server now dies at startup
992 if it detects a valid pid file on his path. The server would
993 die anyway in this circumstance, because of the bind() failure.
994 Affected file silcd/silcd.c.
996 * No longer compiling lib/dotconf.
998 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1000 * Fixed JOIN command parsing not to crash. Affected file
1001 lib/silcclient/command.c.
1003 * Fied the NICK_CHANGE notify to add the new client entry
1004 even it is resolved. This removes an <[unknown]> nick
1005 thingy bug in the client. Affected file is
1006 lib/silcclient/client_notify.c.
1008 * Do not try to allocate 0 bytes (efence does not like it)
1009 in lib/silccore/silccomand.c when encoding payload.
1011 * Do not take IRCNICK as nickname in Irssi SILC client since
1012 it is not possible to set nickname before hand connecting
1013 the server (TODO has an entry about adding auto-nicking
1016 * Changed the silc_server_command_pending to check whether
1017 there already exists an pending entry with the specified
1018 command, command identifier and pending callback. This is
1019 to fix IDENTIFY and WHOIS related crashes that may register
1020 multiple pending commands with same identifier. Affected
1021 file silcd/command.c.
1023 * Fixed the server to reconnect to the router even if it
1024 was already reconnecting and EOF was received. This to
1025 fix a possibility that the server wouldn't ever try to
1026 auto-reconnect to the router. Affected file silcd/server.c.
1028 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1030 * Fixed the server's password authentication to use the
1031 length of the locally saved password, and not the one
1032 sent in the packet. Affected file silcd/protocol.c.
1034 * Fixed same password authentication problem in the
1035 Authentication Payload handling routines in
1036 lib/silccore/silcauth.c.
1038 * Yet another password authentication problem fixed with
1039 channel password handling in silcd/command.c.
1041 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1043 * If first character of string in silc_parse_userfqdn is '@'
1044 then do not parse it. Affected file is
1045 lib/silcutil/silcutil.c.
1047 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1049 * Fixed minor bug in IDENTIFY command reply sending, which
1050 caused various weird problems during JOIN when it was
1051 resolving names for users. Affected file silcd/command.c.
1053 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1055 * Fixed the IDENTIFY command reply sending to chech better valid
1056 clients. It was possible to send incomplete list of replies.
1057 Affected file silcd/command.c.
1059 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1061 * Added silc_client_command[s]_[un]register functions now to
1062 dynamically register the commands in client library. Removed
1063 the static table of commands. This allows the client library
1064 to call commands without causing the application to know about
1065 what commands library has called.
1067 Removed the INFO command reply kludge to detect when the command
1068 was called by library. Now library use its own command reply
1069 function for INFO command.
1071 Added function silc_client_command_call to call a command.
1072 Application can use it to call command, not access the structure
1075 Now all commands that are sent by the client library (not
1076 explicitly sent by application) use own command reply functions.
1078 Affected files around lib/silcclient/ and in
1079 irssi/src/silc/core/.
1081 * Fixed the WHOIS command reply sending to chech better valid
1082 clients. It was possible to send incomplete list of replies.
1084 Fixed the WHOIS and IDENTIFY to send the request to router
1085 if normal server did not do it and did not find any results.
1087 Affected file silcd/command.c.
1089 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1091 * Moved the internal data from SilcClient context into its
1092 own file, not accesible to application. Affected files
1093 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1094 and other files in client library.
1096 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1098 * Added doc/examples installation target in Makefile.am.pre.
1101 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1103 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1104 commands the found client entry will be removed from the
1105 cache, after notifying application about the error. Affected
1106 file lib/silcclient/command_reply.c.
1108 * Changed the /MSG to check for exact nickname user gave, and
1109 not let `nick' match `nick@host' if it is only one found. Now,
1110 user must type the exact nickname (like nick@host2) even if
1111 there are no more than one same nicks found. This is to avoid
1112 a possibility of sending nickname to wrong nickname since
1113 `nick' could match `nick@host'. Affected file is
1114 irssi/src/core/silc-servers.c.
1116 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1118 * Do not print "you are now server operator" or similar when
1119 giving /away command. Affected files are
1120 irssi/src/silc/core/client_ops.c, silc-servers.h.
1122 * Made the silc_server_command_pending_error_check to send
1123 the same command reply payload it received back to the
1124 original sender of the command. This way all arguments
1125 that was received by the server will be received by the
1126 client too. Affected file silcd/command.c.
1128 * Added the silc_idcache_add to return the created cache entry
1129 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1131 * Add global clients to expire if they are not on any channel.
1132 This is because normal server will never know if they signoff
1133 if they are not on any channel. The cache expiry will take
1134 case of these entries. This is done by normal servers only.
1135 The affected files are silcd/command_reply.c,
1136 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1138 * If server receives invalid ID notification for WHOIS or
1139 IDENTIFY and the ID exists in the lists, it is removed.
1140 Affected file silcd/command_reply.c.
1142 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1143 in client then client entry that it matches is searched and
1144 the nickname is printed on the screen for user. Affected
1145 file irssi/src/silc/core/client_ops.c.
1147 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1149 * Use cache entry expire time in the LIST command reply to
1150 purge old entries from the cache after the LIST command
1151 reply has been received. This way we don't have non-existent
1152 entries in the cache for too long. Affected file is
1153 silcd/command_reply.c.
1155 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1157 * If we are normal server, and we've not resolved client info
1158 in WHOIS or IDENTIFY from router, and it is global client,
1159 we'll check whether it is on some channel. If it is not
1160 then we cannot be sure about its validity and will resolve it
1161 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1162 file silcd/command.c.
1164 * Search channel by name (if possible) rather than by ID
1165 in IDENTIFY command's command reply. Affected file is
1166 silcd/command_reply.c.
1168 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1170 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1171 Updated specs and implemented it. Affected file silcd/command.c,
1172 silcd/packet_send.c and silcd/packet_receive.c.
1174 * Implemented the <founder auth> payload handling in the JOIN
1175 command. If provided all conditions for channel joining
1176 except requirement to provide correct passphrase can be
1177 overrided by the channel founder. Updated the protocol specs.
1178 Affected file silcd/command.c.
1180 Added support for founder auth in JOIN command in client
1181 library. Fixed the parsing of the JOIN command now to support
1182 all options as they should be. The affected file is
1183 lib/silcclient/command.c.
1185 * Optimized the WHOIS and IDENTIFY commands to send the request
1186 to router only if it includes nicknames or other names. If
1187 they include only IDs then check the local cache first before
1188 routing. Affected file is silcd/command.c.
1190 * Added channels topic announcements. Affected file is
1191 silcd/packet_receive.c and silcd/server.c.
1193 * Fixed the silc_server_send_notify_topic_set to really destine
1194 the packet to channel. Affected file silcd/packet_send.c.
1196 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1197 library. Affected file lib/silcclient/client_notify.c.
1199 * Added UMODE announcements. Affected file silcd/server.c.
1201 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * Memory leak fixes in:
1205 lib/silcutil/silcsockconn.c
1206 lib/silcske/silcske.c
1207 lib/silcske/groups.c
1209 lib/silccrypt/silcpkcs.c
1210 lib/silccore/silccommand.c
1211 lib/silccore/silcidcache.c
1216 * ROBOdoc documented the lib/silcske/groups.h file and a
1217 bit changed the interface for better.
1219 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1221 * Update the client entry context in the ID cache after
1222 nick change. Affected file lib/silcclient/command.c.
1223 Fixes the CUMODE command when regaining founder privileges,
1224 and a little WHOIS problem.
1226 * Fixed silc_net_gethostbyname to correctly call the
1227 inet_ntop. Affected file lib/silcutil/silcnet.c.
1229 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1231 * Added IPv6 support checking to the configure.in.pre, added
1232 also --enable-ipv6 option to override the check. Affected
1233 file configure.in.pre.
1235 * The silc_thread_create now calls the start function
1236 directly if threads support is not compiled in. Removes
1237 ugly #ifdef's from generic code. Affected files are
1238 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1240 * Added silc_net_gethostby[name/addr]_async to asynchronously
1241 resolve. Affected files are lib/silcutil/silcnet.[ch].
1243 * Added support for rendering IPv6 based server, client and
1244 channel IDs. Affected file lib/silcutil/silcutil.c.
1246 * Added support for creating IPv6 based server IDs. Affected
1247 file is silcd/serverid.c.
1249 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1251 * Added silc_net_gethostby[addr/name] into the
1252 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1253 routines. Added silc_net_is_ip[4/6]. Affected file is
1254 lib/silcutil/unix/silcunixnet.c. All routines that take
1255 address as argument now supports both IPv4 and IPv6 addresses.
1257 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1259 * Fixed LIST command reply sending in server. Affected file
1262 * Server now sends the kicker's client ID in the KICK notify
1263 to the kicked client. Affected file silcd/command.c.
1265 * The client library now parses the kickers client ID and
1266 UI displays it. Affected files lib/silcclient/client_notify.c
1267 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1269 * Made all payload parsing function prototypes consistent.
1270 They all take now const unsigned char * and uint32 pair as
1271 the payload data instead of SilcBuffer. Changes all around
1272 the source tree. Other unsigned char* -> const unsigned char*
1273 changes around the tree as well.
1275 * Optimized SFTP client and server packet sending not to
1276 allocate new buffer for each packet but to recycle the
1277 first allocated buffer. Affected files are
1278 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1280 * Optimized the SFTP client to use SilcList instead of
1281 SilcDList for requests, because it is faster. Affected file
1282 is lib/silcsftp/sftp_client.c.
1284 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1285 into lib/silccore/silcid.[ch].
1287 Renamed silcpayload.[ch] into silcargument.[ch].
1289 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1291 * If client entry is deleted with active key agreement
1292 session, abort the session.
1294 The silc_client_abort_key_agreement now calls the completion
1295 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1297 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1300 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1302 * Don't use __restrict in older GCC's. Affected file is
1303 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1305 * silc_net_localhost now attempts to reverse lookup the
1306 IP/hostname. Affected file lib/silcutil/silcnet.c.
1308 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1309 command. It can be used to gain founder privileges at
1310 the same time when joining the channel.
1312 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1313 kicker's client ID as well. Updated protocol specs.
1315 Defined that the server must send SILC_COMMAND_IDENTIFY
1316 command reply with error status to client who sent
1317 private message with invalid client ID.
1319 Updated the protocol specification.
1321 * Added silc_server_send_command_reply to send any
1322 command reply. Affected file silcd/packet_send.[ch].
1324 * Added silc_id_payload_encode_data to encode ID payload
1325 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1327 * The server now send IDENTIFY command reply with error
1328 status if client ID in private message is invalid. Affected
1329 file silcd/packet_receive.c.
1331 * Save the server key file with server's IP address in
1332 the filename instead of hostname. The affected file is
1333 irssi/src/silc/core/client_ops.c.
1335 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1337 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1340 * Added libtool support for compiling shared objects in
1341 lib/silcsim. Affected file configure.in.pre and
1342 lib/silcsim/Makefile.am. Original patch by cras.
1344 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1346 * Pid file configuration, and server's config file fixes
1347 patch by toma. Updated CREDITS file.
1349 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1351 * Fixed silc_client_channel_message to not try to decrypt
1352 the message twice if it resolved the destination client
1353 information. This could cause of dropping one channel
1354 message. Affected file lib/silcclient/client_channel.c.
1356 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1359 lib/silcclient/client.c. This function is used when the SILC
1360 Client is run under some other scheduler, or event loop or
1361 main loop. On GUI applications, for example this may be
1362 desired to used to run the client under the GUI application's
1363 main loop. Typically the GUI application would register an
1364 idle task that calls this function multiple times in a second
1365 to quickly process the SILC specific data.
1367 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1369 * Fixed silc_server_drop() for dropping the supplementary
1370 groups as well, this could cause a security hole on some
1373 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1375 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1378 * Write PID file after dropping privileges. Added -F option
1379 to run server on foreground. A patch by debolaz.
1380 Affected files silcd/server.c, silcd/silcd.c.
1382 * Fixed MOTD to return the MOTD file server name. Affected
1383 file silcd/command.c.
1385 * Added INFO command reply handling to the Irssi SILC Client.
1386 Affected file irssi/src/silc/core/client_ops.c.
1388 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1390 * Fixed the silc_idcache_list_* routines to really support
1391 the dynamic list. Fixes a crash. Affected file is
1392 lib/silccore/silcidcache.c.
1394 * Fixed the LIST command reply to really call LIST command's
1395 pending callbacks. Affected file silcd/command_reply.c.
1397 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Update conn->local_entry->nickname after giving NICK
1400 command. Affected file lib/silcclient/command.c.
1402 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1404 * Added the [pid] option to the silcd configuration file
1406 Affected files: serverconfig.[ch] and silcd.c
1408 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1410 * Save fingerprint in WHOIS command reply in server.
1411 Affected file silcd/command_reply.c.
1413 * Fixed NICK commands pending callback registration.
1414 Affected file lib/silcclient/command.c.
1416 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Use ++server->cmd_ident when sending commands in server,
1419 instead of random number. Affected file silcd/command.c.
1421 * Fixed GETKEY command reply to call actually GETKEY pending
1422 command callbacks. Affected file silcd/command_reply.c.
1424 * A bit stricter check for nicknames. Check for same nickname
1425 in NICK command also. Affected file silcd/command.c.
1427 * Do not call INFO command everytime client ID changes, only
1428 during first connecting. Affected file lib/silcclient/client.c.
1430 * Set the new nickname only after successful command reply for
1431 NICK command is returned by server. Affected file
1432 lib/silcclient/command.c.
1434 * Remove nicknames from nicklist during server_signoff notify.
1435 Should fix /NAMES bit more. The affected file is
1436 irssi/src/silc/core/silc-channels.c.
1438 * Added `fingerprint' field to the SilcIDListData in the
1439 silcd/idlist.h to hold the fingerprint of the client's
1442 Send the fingerprint of the client's public key in WHOIS
1445 Affected files silcd/command.c, and silcd/idlist.[ch].
1447 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1448 create fingerprint from given data.
1450 * Show the fingerprint of the client's public key in WHOIS.
1451 Affected files irssi/src/module-formats.[ch] and
1452 irssi/src/silc/core/client_ops.c.
1454 * Format the multiple same nicknames also during JOIN and
1455 NICK_CHANGE notifys. Affected file is
1456 lib/silcclient/client_notify.c.
1458 * Do not print error on screen for invalid private message
1459 payload since it can come if someone is sending private
1460 messages with wrong key. Affected file
1461 lib/silccore/silcprivate.c.
1463 * Fixed multiple concurrent /PING crash. Affected file
1464 lib/silcclient/command.c.
1466 * Changed the wrong ID encoding. All IP addresses must be
1467 in MSB first order in encoded format. They were encoded
1468 wrong and was in LSB format. Affected files are
1469 silcd/serverid.c, lib/silcutil/silcutil.c.
1471 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1473 * Call the `connect' client operation through the scheduler
1474 in case of error. Affected file lib/silcclient/client.c.
1476 * Call the `failure' client operation even if the error
1477 occurred locally during a protocol. Affected file is
1478 lib/silcclient/protocol.c.
1480 * Added support of sending LIST command to router from normal
1481 server. This way normal server can get list of all channels
1482 in the network too. Fixed the channel list sending in the
1483 server too. Affected files are silcd/command.c, and
1484 silcd/command_reply.[ch].
1486 * Added silc_server_update_channels_by_server and
1487 silc_server_remove_channels_by_server. They are used during
1488 disconnection of primary router and in backup router protocol.
1489 Affected file silcd/server_util.[ch], silcd/server.c and
1490 silcd/server_backup.c.
1492 * Fixed channel adding to global list in IDENTIFY command
1493 reply in server. Affected file silcd/command_reply.c.
1495 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1497 * If the incoming packet type is REKEY or REKEY_DONE process
1498 that packet always synchronously. Fixes yet another MAC
1499 failed error on slow (dialup) connections. Affected file
1500 lib/silcclient/client.c and silcd/server.c.
1502 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1504 * Call check_version SKE callback for initiator too. Affected
1505 file lib/silcske/silcske.c.
1507 * Implemented fix for security hole found in the SKE that was
1508 fixed in the specification few days back; the initiator's
1509 public key is now added to the HASH value computation.
1510 Added backwards support for the old way of doing it too, for
1511 old clients and old servers. Affected file is
1512 lib/silcske/silcske.c.
1514 * Enabled mutual authentication by default in SKE. If initiator
1515 is not providing mutual authentication the responder will
1516 force it. This will provide the proof of posession of the
1517 private key for responder. The affected files are
1518 lib/silcclient/protocol.c and silcd/protocol.c.
1520 * Do not cache anymore the server's public key during SKE.
1521 We do mutual authentication so the proof of posession of
1522 private key is done, and if the server is authenticated in
1523 conn auth protocol with public key we must have the public
1524 key already. Affected file silcd/protocol.c.
1526 * Added new global debug variable: silc_debug_hexdump. If
1527 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1528 file lib/silcutil/silclog.[ch].
1530 * Fixed compilation warning due to char * -> const char *.
1531 Affected files lib/silcutil/silcnet.h, and
1532 lib/silccore/silcauth.[ch].
1534 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1536 * Fixed CMODE command when new channel key was created. If
1537 the creation failed the old key was removed. Next time giving
1538 same command would crash the server since the old key was
1539 freed already. Affected file silcd/command.c.
1541 * Fixed the silc_server_announce_get_channels to not crash
1542 on reconnect. Affected file silcd/server.c.
1544 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1546 * Added silc_log_set_debug_string function to set a regex
1547 string to match for debug output. Only the function names,
1548 or filenames matching the given debug string is actually
1549 printed. This way it is possible to filter out those debug
1550 strings that user is not interested in.
1552 Fixed a bug in silc_string_regexify.
1554 Affected files lib/silcutil/silclog.[ch], and
1555 lib/silcutil/unix/silcunixutil.c.
1557 * Changed the -d options in both server and Irssi SILC client
1558 to take the debug string as argument. Affected files
1559 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1561 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1563 * Added silc_hash_babbleprint to create a Bubble Babble
1564 Encoded fingerprint. The encoding is developed by Antti
1565 Huima (draft-huima-babble-01.txt), and it creates human
1566 readable strings out of binary data. Affected file
1567 lib/silccrypt/silchash.[ch].
1569 * Print the babble print now in addition of fingerprint as well
1570 in Irssi SILC client. Affected files are
1571 irssi/src/fe-common/silc/module-formats.[ch],
1572 irssi/src/fe-common/silc/core/client_ops.c.
1574 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1576 * Fixed a security problem found in SKE. The initiator's
1577 public key too is now added to the HASH hash value creation
1578 which is signed by the responder to create the SIGN value.
1579 This will prevent anyone in the middle to lie to the responder
1580 about the initiator's public key. If this is done now, the
1581 man in the middle will get caught. Updated the protocol
1584 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1586 * Better installation directory handling. Configure module
1587 paths and other paths automatically to example_silc* files
1588 in doc/. A patch by toma.
1590 * Fixed compiler warning from MPI library, and from SILC RNG.
1593 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1594 It can be configured with ./configure. A patch by toma.
1596 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1598 * Find correct make to use in prepare-clean. A patch by
1599 toma. Affected file prepare-clean.
1601 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1603 * Added irssi variables use_auto_addr, auto_bind_ip,
1604 auto_bind_port and auto_public_ip.
1606 * Changed the interface for silc_client_send_key_agreement
1607 in lib/silcclient/silcapi.h
1611 irssi/src/silc/core/silc-core.c
1613 lib/silcclient/silcapi.h
1614 irssi/src/silc/core/silc-channels.c
1615 lib/silcclient/client_keyagr.c
1618 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * Added silc_pkcs_public_key_compare to compare two
1621 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1623 * Check that the client who set the founder mode on the
1624 channel is the same client that is giving the founder
1625 mode to itself. It is done by comparing the saved public
1626 key (it is saved even in the authentication is passphrase).
1627 Affected file silcd/command.c.

1635 client library. Affected file lib/silcclient/client.c.
1637 * Fixed the silc_client_packet_parse to not to increase
1638 the packet sequence number if the conn->sock and the
1639 current socket connection is not same. This can happen
1640 for example during key agreement when the conn includes
1641 multiple socket connections (listeners). Affected file
1642 lib/silcclient/client.c.
1644 * The sender of the file transfer request now provides also
1645 the pointer (listener) for the key exchange protocol. If
1646 the listener cannot be created then it sends empty key
1647 agreement and lets the receiver provide the listener.
1649 Added `local_ip' and `local_port' arguments to the
1650 silc_client_file_send. If they are provided they are used,
1651 if not then it will attempt to find local IP address, if
1652 not found or bind fails then the remote client will provide
1655 Affected files are lib/silcclient/client_ftp.c and
1656 lib/silcclient/silcapi.h.
1658 * Extended the FILE SEND command to support defining the

1665 of the client's public key (if the proof of posession of the
1666 corresponding private key is verified by the server).
1667 Updated to the protocol specification.
1669 * Added support of receiving the client's public key's
1670 fingerprint in command reply in client library. Affected
1671 file is lib/silcclient/command_reply.c, and
1672 lib/silcclient/idlist.[ch].

1731 preserve the WHOWAS info for the client. Affected file
1732 silcd/server_util.c.
1734 * Fixed SERVER_SIGNOFF notify handling in the server. The
1735 server is now able to process incoming SERVER_SIGNOFF notify
1736 for a server that it doesn't even know about. It will remove
1737 the clients provided in the notify. Affected file
1738 silcd/packet_receive.c.
1740 * Check for partial packet in data queue after every packet that
1741 was found from the queue. Return and wait for more data if
1742 there is partial data in queue. Affected file is

1760 irssi/src/fe-common/silc/module-formats.[ch].
1762 * Wrote a help file for FILE command.
1764 * Added silc_rng_global_get_byte_fast to get not-so-secure
1765 random data as fast as possible. Random data is read from
1766 /dev/urandom if available and from the SILC RNG if not
1767 available. It is used in padding generation. Affected file
1768 lib/silccrypt/silcrng.[ch].
1770 * All packets in client library are now processed synchronously.
1771 Optimized packet processing a lot. Affected file
1772 lib/silcclient/client.c.

1783 * Assure that silc_client_notify_by_server_resolve does not
1784 resolve the client information multiple times. If it cannot
1785 be found by the first it cannot be found at all. Affected
1786 file lib/silcclient/client_notify.c.
1788 * Fixed WHOWAS command reply calling. Affected file
1789 lib/silcclient/command_reply.c.
1791 * Removed all references to silc_idlist_get_client from the
1792 Irssi SILC client since that call is internal call used by
1793 the library. The Irssi SILC client will use now client
1794 retrieval functions found in silcapi.h.
1796 * Fixed a bug in resolving nickname info before sending
1797 private message. It used freed memory. Affected file
1798 irssi/src/silc/core/silc-servers.c.

1820 Affected file lib/silcutil/silcnet.[ch].
1822 * If key exchange or rekey protocol is active for a connection
1823 parse all packets syncronously since there might be packets
1824 in packet queue that we are not able to process without first
1825 processing packets before them. Affected file silcd/server,
1826 lib/silcclient/client.c.
1828 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1829 whether library should continue processing the packet.
1830 Affected file lib/silccore/silcpacket.h.

1903 * Call the silc_server_udpate_servers_by_server in the
1904 primary router that comes back online in the backup resuming
1905 protocol. Otherwise it routes packets wrong. Affected file
1906 silcd/server_util.[ch], silcd/server_backup.c.
1908 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1911 lib/silcutil/silcbuffmt.[ch].

1916 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1917 length for maximum padding up to 128 bytes). Affected
1918 file lib/silccore/silcpacket.h.
1920 * Removed all backwards support for old 0.5.x MAC thingies.
1921 The SILC packet header change makes it impossible to be
1922 backwards compatible.
1924 * Send the ENDING packet with timeout in the backup resuming
1925 protocol. This is to assure that all routers has connected
1926 to the primary router. Affected file silcd/server_backup.c.
1928 * Changed the RNG to take the first IV from random data. It
1929 used to take it from zero actually. Changed the RNG also

1936 (the packet length) encrypted. Affected files aroung the
1937 code tree, lib/silccore/silcpacket.[ch]. Removed the
1938 SilcPacketCheckDecrypt callback. It is not needed anymore
1939 since the silc_packet_receive_process will determine now

1953 * Allow backup router to announce servers. All servers
1954 announced by backup router are added to the global list
1955 automatically. Update hte server's socket to our primary
1956 router also when backup router announces a server.
1957 Affected file silcd/packet_receive.c.
1959 * Do not update the client->router in the function
1960 silc_server_udpate_clients_by_server if the client is on
1961 global list. We might fail to find any specific server
1962 for locally connected clients and local cell clients. They
1963 should still use the `from' and not `to' as client->router.
1964 This fixes backup router resuming protocol. Affected file
1965 silcd/server_util.c.
1967 * Decrease channel statistics count only if the channel
1968 deletion worked. Affected files are silcd/server.c and
1969 silcd/server_util.c.

1989 to the router it came from. Affected file is
1990 silcd/packet_send.c. Fixed memory leak too.
1992 * Announce informations for incoming router connection, but
1993 only after checking if it is replaced by backup router.
1994 Affected file silcd/packet_receive.c.
1996 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1999 router environment. Affected file silcd/server_backup.c.
2001 * Route packet only to one router in the function
2002 silc_server_packet_send_to_channel. Affected file is
2003 silcd/packet_send.c.
2005 * Fixed silc_server_send_notify_dest to set the broadcast
2006 flag. Fixed the silc_server_send_notify_topic to actually
2007 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2008 Affected file silcd/packet_send.c.
2010 * Changed the SFTP Filesystem interface. Changed the
2011 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2012 the filesystem operation function. The SilcSFTPFilesystem
2013 is now a context that is allocated by all filesystem allocation
2014 functions and it already includes the operations structure
2015 and filesystem specific context. It is given as argument
2016 now to the silc_sftp_server_start. This made the interface
2017 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2018 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2020 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Changed the backup router adding and getting interfaces
2023 in the server. The router that will be replaced by the

2143 of the internet draft is lib/silccore/silcpacket.h.
2145 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2146 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2147 is used as part of backup router protocol when the primary
2148 router of the cell is back online and wishes to resume
2149 the position as primary router.
2151 * Redefined the MAC generation keys in the protocol. The
2152 same key is not used anymore in both direction. Both
2153 direction will now use different keys for sending and
2154 receiving. This fixes a potential security flaw. This
2155 change causes incompatibilities in the protocol.
2157 * Redefined also the MAC computation from the packet.
2158 An packet sequence number is now added to the MAC
2159 computation. This prevents possible replay attacks against
2160 the protocol. This change too causes incompatibilities
2163 Added `sequence' field to the SilcPacketContext to hold
2164 the current sequence number for the packet.
2166 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2168 * Added `created' field to the SilcIDListData in the file
2169 silcd/idlist.h to indicate the time when the entry was
2172 * Added `created' field to the SilcChannelEntry too. Affected
2173 file silcd/idlist.h.
2175 * Added `creation_time' aguments to all the announcement functions
2176 in the server. If it is provided then only the entries that
2177 was created after the provided time frame are actually
2178 announced. Affected file silcd/server.[ch].
2180 * The protocol says that the Channel ID's IP address must be
2181 based on the router's IP address. Added check for this in
2182 the silc_server_new_channel when processing incoming New Channel
2183 Payload. Affected file silcd/packet_receive.c.
2185 * Print out the correct version with --version in SILC client.
2186 Affected file irssi/src/silc/core/silc-core.c.
2188 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Fixed WHOWAS command to check for completnes of the client
2191 entry always, not just when the command is coming from client.
2192 Affected file silcd/command.c.
2194 * Added new function silc_server_packet_queue_purge to purge the
2195 outgoing data queue to the network. After the function returns
2196 it is guaranteed that the outgoing packet queue is empty.
2197 Affected file silcd/packet_send.[ch].
2199 * Purge the outgoing packet queue in the rekey protocol's final
2200 callback to assure that all rekey packets go to the network
2201 before quitting the protocol. Affected file silcd/server.c.
2203 * Added silc_client_packet_queue_parse as similar function as
2204 in server to the client library. The affected file is
2205 lib/silcclient/client.c.
2207 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2209 * Splitted silcd/server.c and created silcd/server_util.[ch]
2210 for utility functions.
2212 * Added new socket flag SILC_SF_DISABLED to indicate that the
2213 connection is open but nothing can be sent to or received from
2214 the connection. Affected file lib/silcutil/silsockconn.[ch].
2215 The checking for disabled socket is checked in the low level
2216 silc_socket_write and silc_socket_read functions.
2218 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2220 * Allow only nicknames and channel names that fits into the
2221 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2223 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2225 * When processing JOIN command reply in server check that if
2226 the channel exists in our global list we'll move it the local
2227 list. Affected file silcd/command_reply.c.
2229 * Fixed the check whether client is joined on the channel already
2230 in JOIN command. Affected file lib/silcclient/command.c.
2232 * Fixed the JOIN command reply to check whether the channel
2233 already exists. Affected file lib/silcclient/command_reply.c.
2235 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * Added silc_ske_status_string to map the SKE error numbers
2238 to readable strings. The affected files are
2239 lib/silcske/silcske[_status].[ch].
2241 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2243 * Do not show the private channels on the WHOIS channel list
2244 as it is not allowed by the protocol. The affected file is
2247 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2249 * Assure that the packet length digged from the actual packet
2250 is something sensible in the silc_packet_decrypt_rest_special
2251 in lib/silccrypt/silcpacket.c.
2253 * Free and NULL the allocated pointer in silc_hmac_alloc if
2254 the HMAC allocation fails. The affected file is
2255 lib/silccrypt/silchmac.c.
2257 * Print the selected security properties to the log files in
2258 the server. Affected file silcd/protocol.c.
2260 * Add SKE's reference counter even if calling the completion
2261 callback manually. Otherwise it goes negative, although it
2262 does not cause any problems. The affected file is
2263 lib/silcske/silcske.c.
2265 * Remove the client entry with short timeout after giving the
2266 KILL command. Affected file lib/silcclient/command.c.
2268 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2269 case all found clients are already disconnected (WHOWAS would
2270 found them) in the server. Affected file silcd/command.c.
2272 * Update the last_receive (time of last data received) to be
2273 updated only when received private or channel message so that
2274 the idle time showed in WHOIS makes more sense.
2276 * Added boolean field `valid' in to the SilcClientEntry in the
2277 client library to indicate whether the entry is valid or not.
2278 This fixes the nickname change bug on channel when changing
2279 the nickname to be same than the old (like nick to Nick) the
2280 nickname formatter doesn't set the new nick anymore to Nick@host.
2281 Affected file lib/silcclient/idlist.[ch].
2283 * Now actually fixed the nickname changing on disconnection.
2284 Added new function silc_change_nick to the Irssi SILC Client.
2285 Affected file irssi/src/silc/core/client_ops.c,
2286 irssi/src/silc/core/silc-nicklist.[ch].
2288 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2290 * Check that the public key exists in the GETKEY command before
2291 trying to encode it. Affected file silcd/command.c.
2293 * Print some notifications on received public keys with GETKEY
2294 command in the Irssi SILC Client. Affected files are
2295 irssi/src/fe-common/silc/module-formats.[ch],
2296 irssi/src/silc/core/client_ops.c.
2298 * Use IDENTIFY command to resolve the server information in the
2299 GETKEY command instead of INFO command. Affected file
2300 lib/silcclient/command.c.
2302 * All command reply functions in the client library now calls
2303 the pending command reply callbacks even if an error has
2304 occurred. The server has done this a long time and now it was
2305 time to move the client library to this as well. Now all
2306 errors can be delivered back to the pending command reply
2307 callbacks if necessary. Affected files are
2308 lib/silcclient/command[_reply].[ch].
2310 * Change the nickname on disconnection back to the username
2311 because in reconnect the server will enforce it to it anyway.
2312 Affected file irssi/src/silc/core/silc-servers.c.
2314 * Fixed a config file parsing bug in the Irssi SILC client.
2315 Affected file irssi/src/silc/core/clientconfig.c.
2317 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2319 * When printing the channel mode on JOIN, verify that the
2320 channel key and channel's HMAC are valid. Affected file
2321 irssi/src/silc/core/client_ops.c.
2323 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2325 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2326 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2327 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2329 * Removed channel key rekey task deleting from the function
2330 silc_server_save_channel_key. Affected file silcd/server.c.
2331 Added explicit timeout task context instead that is used to
2332 delete the task if we are registering a new task before the
2333 new task has elapsed.
2335 * When channel key rekey occurs the client library now saves
2336 the old channel key for a short period of time (10 seconds) and
2337 is able to use it in case some is still sending channel
2338 messages encrypted with the old key after the rekey. Affected
2339 file lib/silcclient/[idlist.h|client_channel.c].
2341 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2343 * Added check to the silc_server_new_id_real to not accept
2344 new ID if it is the sender's own ID. Affected file is
2345 silcd/packet_receive.c.
2347 * Assure that we do not announce ourself or the one we've
2348 sending our announcements when we're router and are announcing
2349 servers to our primary router. Affected file silcd/server.c.
2351 * Fixed silc_server_command_identify_check_client to assemble
2352 correct WHOIS packet. It send corrupted WHOIS packet and
2353 caused problem with router to router connections. Affected
2354 file silcd/command.c.
2356 Fixed also silc_server_command_whois_check the same way
2357 as for the IDENTIFY command.
2359 * Added new SilcIDListStatus to the server in the SilcIDListData
2360 structure. The status now includes the current status of
2361 the entry (like registered, resolved etc.). Affected file
2362 silcd/idlist.[ch]. Defined a bunch of different status types
2363 as well. This replaced the old boolean registered field as well.
2365 Added resolve_cmd_ident field to the SilcClientEntry structure
2366 too so that if the entry is for example being resolved so
2367 another command may attach to the same pending command reply
2368 without requiring to resolve the same entry again. This concept
2369 should optimize the WHOIS and the IDENTIFY resolving under
2370 heavy load by taking away unnecessary resolving for entries
2371 that are being resolved already.
2373 Added support for adding multiple pending commands for one
2374 command idenfier. Affected file silcd/command[_reply].[ch].
2376 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2377 before deleting the data. Otherwise the hash table will have
2378 freed data in comparison functions. Affected file is
2379 silcd/command_reply.c.
2381 * Fixed silc_idlist_replace_client_id to add the new entry to
2382 the cache with NULL nickname. Otherwise there will be invalid
2383 memory as the nickname after the nickname is freed. Affected
2384 file silcd/packet_receive.c.
2386 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2387 saved into wrong slots because the previous number of entries
2388 was not taken into account. Affected file silcd/idlist.c.
2389 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2391 * If we are router and we receive JOIN notify to a channel that
2392 does not have any users then notified client is marked as the
2393 channel founder, as it is it. The affected file is
2394 silcd/packet_receive.c
2396 * Added to the extended hash table API's table_del_*ext functions
2397 the destructor as argument too, so that the caller can decide
2398 which destructor to use or whether to use destructor at all.
2399 Affected file lib/silcutil/silchashtable.[ch].
2401 * Fixed ID Cache purging. It actually deleted the entries from
2402 the hash table after the data was freed. The hash table ended
2403 up comparing freed memory. The affected file is
2404 lib/silccore/silcidcache.c.
2406 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Fixed Irssi SILC client's KILL command's HELP syntax.
2410 * The USERS command now resolves the detailed user information
2411 if the userinfo field is missing. Affected file is
2412 lib/silcclient/command_reply.c.
2414 * Do not print error in silc_file_read if the read file does
2415 not exist. Just silently return NULL. Affected file is
2416 lib/silcutil/silcutil.c.
2418 * Fixed the silc_log_output to not wine about NULL filename
2419 and to not create some bogus " " filename. Affected file is
2420 lib/silcutil/silclog.c.
2422 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2424 * Fixed various printing bugs on the user interface in the
2425 Irssi SILC Client. Minor changes that were forgotten from
2428 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * Fixed the configure.in.pre and the compilation and distribution
2431 environment to support the new autoconf 2.52. That version is
2432 now required to compile the CVS trunk.
2434 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2437 to generally parse user@fqdn format strings. Affected file
2438 lib/silcutil/silcutil.c.
2440 * Added nickname_format and nickname_force_format fields to the
2441 SilcClientParams structure. The first one defines the format
2442 for the nicknames that the library will enforce if the receives
2443 multiple same nicknames. The second one is boolean value and
2444 can be used to force the library to always enforce the format
2445 to the nicknames regardles whether there are multiple nicknames
2446 or not. This configurable formatting was employed to flexibly
2447 support accessing multiple nicknames from the user interface.
2448 The userinterface can now set the nicknames to what ever format
2449 they prefer. Affected file lib/silcclient/silcapi.h.
2451 Added function silc_client_nickname_format to the file
2452 lib/silcclient/idlist.c. It performs the nickname formatting.
2454 Added new field `hostname´ to the SilcClientEntry context.
2455 It holds the hostname of the client. Affected file is
2456 lib/silcclient/idlist.h.
2458 * Irssi SILC Client sets the nicknames in nick@hostn format.
2459 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2460 irssi/src/silc/core/silc-core.c.
2462 The WHOIS printing now also shows both the real nickname and
2463 the formatted nickname so that user knows how to access the
2464 user if there are multiple same nicknames cached. Affected
2465 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2466 printing formatting too to take the hostname now as a separate
2467 argument. The Affected file is
2468 irssi/src/fe-common/silc/modules-formats.[ch].
2470 * Changed the silc_client_get_clients_local to accept the formatted
2471 nickname as argument. It accepts the real nickname too but the
2472 formatted nickname can be used to find the true entry from
2473 multiple entries. Affected file lib/silcclient/silcapi.h and
2474 lib/silcclient/idlist.c.
2476 * Added nickname_format_parse field to the SilcClientParams.
2477 It is a callback function provided by the application to parse
2478 the nickname out of the formatted nickname string. The library
2479 calls it to get the nickname from the formatted string. Since
2480 the application generally knows better the format of the nickname
2481 string it parses it instead of the library, even though library
2482 encodes the formatted string. If the callback function is not
2483 provided then the library will use the string as is. The
2484 affected file is lib/silcclient/silcapi.h.
2486 * All the nickname strings passed to the client library in
2487 commands are now expected to be formatted nickname strings.
2488 If the command does not support the formatted nickname string
2489 it will assume that the sent string is the actual nickname.
2490 Affected file lib/silcclient/command.c.
2492 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2494 * Added public key authentication support to OPER and SILCOPER
2495 commands in the client library. Affected file is
2496 lib/silcclient/command.c.
2498 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2500 * Changed the get_auth_methdod client operation to be asynchronous.
2501 It can be async if the application resolves the authentication
2502 method from the server during the negotiation. Added new
2503 SilcGetAuthMeth completion callback that the application will
2504 call after resolving the authentication method.
2506 Added function silc_client_request_authentication_method that
2507 the application can use to resolve the authentication method
2508 from the server. Added also SilcConnectionAuthRequest callback
2509 that the library will call after the server has replied. The
2510 application can call this function if it does not know the
2511 current authentication method.
2513 Affected files are lib/silcclient/client.c and
2514 lib/silcclient/silcapi.h.
2516 * The Irssi SILC client now automatically resolves the authentication
2517 method incase any configuration information is not present (and
2518 currently there never is). The affected file is
2519 irssi/src/silc/core/client_ops.c.
2521 * Fixed public key authentication from the client library.
2522 Affected file lib/silcclient/protocol.c. Changed also the
2523 protocol specification about the public key authentication in
2524 the connection authentication protocol. The actual data to be
2525 signed is now computed with a hash function before signing.
2527 * Fixed the public key authentication from the server as well.
2528 Affected file silcd/protocol.c.
2530 * Removed the mlock()'s from the memory allocation routines.
2531 Affected file lib/silcutil/silcmemory.c. The ./configure does
2532 not check anymore for the mlock(). Affected file is
2535 * Fixed USERS command in server to allow the execution of the
2536 command for private and secret channels if the client sending
2537 the command is on the channel. Affected file silcd/command.c.
2539 * Fixed silc_client_get_clients_local to return the clients
2540 count correctly. It could return wrong value. Affected file
2541 lib/silcclient/idlist.c.
2543 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2546 types. The assembler optimizations seemed not to like 64-bit
2547 data types. The assmebler optimizations thus are now enabled
2548 also for BSD systems as opposed to only enable them for Linux.
2550 * Do not check for threads at all on BSD systems. Affected
2551 file configure.in.pre.
2553 * Removed -n and -h options from the Irssi SILC Client since
2554 they are not used in silc.
2556 * Fixed the prime generation to assure that the first digit
2557 of the generated random number is not zero since our conversion
2558 routines does not like number strings that starts with zero
2559 digit. If zero digit is seen the random number is regenerated.
2560 This caused some corrupted RSA keys when the zero first digit
2561 was met. Affected file lib/silcmath/silcprimegen.c.
2563 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2565 * Fixed WIN32 configuration in the ./configure script.
2566 Fixed to include xti.h on environments that has it.
2567 Patches by Carsten Ilchmann and andrew.
2569 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Changed the silc_id_create_client_id to be collision
2572 resistant. It is now assured that there cannot be created
2573 two same client ID's. I suspect that some weird bugs in
2574 the server were actually caused by duplicate Client IDs.
2575 Affected file silcd/serverid.[ch]. A router receiving
2576 new ID now also assures and informs the sending server
2577 if the ID caused collision.
2579 * Changed the silc_id_create_channel_id to also assure that
2580 there are no collisions.
2582 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2584 * Statement about ignoring the Mutual Authentication flag when
2585 performing rekey with PFS was a bit misleading. It is ignored
2586 if it was set in the initial negotiation, it cannot be even
2587 set in the rekey. Fixed in the ke-auth draft. Started the
2588 new versions of the protocol drafts in the doc/.
2590 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Fixed a bug in silc_client_command_identify_save when saving
2593 new channel information. The channel name was no duplicated
2594 and caused crash on exit. Affected file is
2595 lib/silcclient/command_reply.c.
2597 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * Fixed the getkey command handling in the server. Send just
2600 empty OK reply to the sender if the key could not be fetched
2601 (but everything else was ok, like the key just was not available).
2602 Changed the public key parameter to optional in the protocol
2603 specs so that empty OK reply can be sent. Affected file
2606 Added a message to Irssi SILC client to tell to user if the
2607 server did not return a public key.
2609 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Fixed a channel key regeneration bug. It registered new
2612 timeout tasks exponentially until all system resources were
2613 used. Affected file silcd/server.c.
2615 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Added the SILC Document generator to the scripts/silcdoc.
2618 It can be used to generate the Toolkit Reference Manual out
2619 of the source tree. Internally it will also use the RoboDoc
2620 generator now imported in util/robodoc.
2622 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2624 * Added couple of return's in rekey protocol if error orccurred
2625 during the protocol. The execution must be terminated.
2626 Affected file silcd/protocol.c. Also, terminate the protocol
2627 always with timeout.
2629 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2631 * The client's Client ID was created initally from the wrong
2632 nickname (it could have been in format nick@host) in the
2633 silc_server_new_client. Affected file silcd/packet_receive.c
2635 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2637 * Added some SILC_LOG_ERROR's to various error conditions
2638 if client could not be added to ID cache. Affected files
2639 silcd/packet_receive.c and silcd/server.c.
2641 * When client's sock->user_data is freed, NULL also the
2642 client->router and client->connection pointers. Added check
2643 for these pointers being NULL to various places around the
2644 code. Affected file silcd/server.c.
2646 * Added client->data.registered == TRUE checks to various
2647 places around the code to assure that unregistered client's
2648 are not handled when it is not allowed. Affected file
2651 * Added `bool registered' fields to all
2652 silc_idlist_[server|client]_get_* routines to indicate whether
2653 the fetched client needs to be registered or not. Affected
2654 file silcd/idlist.[ch].
2656 * Add your own entry as registered to the ID cache in the
2657 server. Affected file server.c.
2659 * Fixed a bug in silc_server_new_server. The SilcServer was
2660 set as the new server's context instead of SilcServerEntry.
2661 This naturally caused some weird bugs.
2663 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2665 * Do not delete the channel rekey task when adding it
2666 for in silc_server_create_channel_key.
2668 * Changed the silc_server_create_channel_key to return
2669 TRUE or FALSE to indicate the success of the channel key
2672 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * Fixed MSVC++ project files and added missing files to

2679 * Do not add TCP_NODELAY flag if the operating system
2680 does not have it defined. Affected files are
2681 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2683 * Fixed buffer overflow from Irssi SILC Client. Affected
2684 file irssi/src/fe-common/core/themes.c.
2686 * Fixed double free in client library in the file
2687 lib/silcclient/client.c when disconnecting from server.
2689 * Applied double free patch from cras to Irssi SILC client.
2690 Affected files irssi/src/core/[modules/expandos].c
2692 * Fixed the disconnection handling to Irssi SILC Client.
2693 The application must call silc_client_close_connection
2694 in ops->connect client operation in case of failure of
2695 the connection. Affected file is
2696 irssi/src/silc/core/client_ops.c.
2698 * Do not set sock->protocol to NULL in the function
2699 silc_client_close_connection after executing the protocol's
2700 final callback since the sock might not be valid anymore.
2701 Affected file lib/silcclient/client.c.
2703 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2705 * Do not enable SILC_THREADS if the linking with libpthread
2706 did not happen. Affected file configure.in.pre.
2708 * Added notion to protocol specification that server must
2709 verify the sent authentication payload with CMODE when
2710 setting the channel founder key. Implemented it to the
2711 server. Affected file silcd/command.c.
2713 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2715 * Added _EXTRA_DIST SILC distribution variable to the
2716 distributions file. It is used to conditionally add extra
2717 files or directories to the specific distribution. Affected
2718 files ./prepare, Makefile.am.pre and distributions.

2723 * Added README.WIN32 for instructions to compile the Toolkit
2726 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2728 * Fixed a double free in disconnection in the server. Affected
2729 file is silcd/server.c.
2731 * Fixed the lib/silcske/groups.c to work now also with GMP
2732 MP library. The string conversion did not work when using
2733 specific base and the base is indicated in the string as well.
2735 * Created win32/ directory which now includes MSVC++ specific
2736 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2737 It will appear only in the toolkit distribution
2739 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Changed the key material distribution function in case when
2742 the hash output is too short. The data is now concatenated
2743 a bit differently than it used to. Made the change to the
2744 SKE protocol specification.
2746 * Added better GMP detection to configure.in.pre. A patch
2749 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2751 * Fixed a minor bug in SKE that might cause some problem on
2752 some platforms. Affected file lib/silcske/silcske.c.
2754 * Added the cookie checking for initiator in the SKE. It checks
2755 that the responder returns the sent cookie unmodified. The
2756 affected file is lib/silcske/silcske.c. Added new SKE
2757 error type INVALID_COOKIE that can be sent during the
2758 negotiation. Fixed some memory leaks as well.
2760 * Added the "invalid cookie" error message to Irssi SILC client's
2763 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * Added `task_max' field to the SilcClientParams to indicate
2766 the maximum tasks the scheduler can handle. If set to zero,
2767 default values are used. Affected file lib/silcclient/silcapi.h.
2769 * Fixed memory leaks in silc_client_close_connection. Affected
2770 file lib/silcclient/client.c.
2772 * Added silc_client_del_client_entry to client library to free
2773 all memory of given client entry. Affected file is
2774 lib/silcclient/idlist.[ch].
2776 * Added new functions silc_client_del_channel and
2777 silc_client_del_server to delete channel and server entries.
2778 Affected file lib/silcclient/[silcapi.h/idlist.c].
2780 * Removed silc_client_del_client_by_id from silcapi.h.
2782 * Fixed the INFO command to return the server's own info
2783 correctly when querying by Server ID. Affected file is
2786 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * Removed the non-blocking settings in WIN32 code in the
2789 silc_sock_[read/write] and added SleepEx instead. Affected
2790 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2791 of input data is now checked with FIONREAD and ioctlsocket.
2793 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Call silc_schedule_task_del_by_context in the
2796 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2797 Affected file lib/silccore/silcprotocol.c.
2799 * Call silc_protocol_cancel for active protocols in the
2800 silc_server_close_connection if the funtion
2801 silc_server_free_sock_user_data has not been called.
2802 Affected file silcd/server.c.
2804 * Generic tasks cannot be deleted using the del_by_fd
2805 task deleting function since generic tasks does not match
2806 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2808 * Added a notion to SILCOPER help file that the SILCOPER works
2809 only on router server, not on normal server.
2811 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2813 * Added for WIN32 support for the new scheduler as well.
2814 Affected file lib/silcutil/win32/silcwin32schedule.c.
2816 * Fixed the SHA1 implementation to work on various platforms.
2818 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2820 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2821 API. It is part of the scheduler now. Everything else is
2822 as previously but some functions has changed their names.
2823 Checkout the lib/silcutil/silcschedule.h for the interface.
2824 Updated all applications to use the new interface. Affected
2825 files are lib/silcutil/silcschedule.[ch].
2827 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Found a bug in the SKE implementation. The HASH value,
2830 specified by the protocol, was not computed correctly. The
2831 public key of the responder was not added to the computation
2832 even though it is mandatory. Affected file lib/silcske/silcske.c.
2833 This unfortunately causes incompatibilities with older
2834 clients and servers.
2836 * Added WIN32 specific network init and uninit functions:
2837 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2838 the Winsock2. Affected file lib/silcutil/silcnet.h and
2839 lib/silcutil/win32/silcwin32net.c.
2841 * Set the socket always to nonblocking mode on WIN32 after
2842 reading data or writing data. Affected file is
2843 lib/silcutil/win32/silcwin32sockconn.c.
2845 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Fixed various compilation problems under WIN32. Affected
2848 files lib/silcutil/win32/silcwin32thread.c and
2849 lib/silcutil/win32/silcwin32schedule.c.
2851 * Removed all _internal.h #includes from public header
2852 files. Internal headers must never be included from
2855 Removed also the lib/silcske/payload_internal.h file.
2857 * All include files that may be needed (public and some others
2858 included by the public headers) by application developers are
2859 now copied to the ./includes directory. It does not copy any
2860 internal headers. Affected file Makefile.defines.pre and all
2861 Makefile.am's under lib/ and subdirs.
2863 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2865 * Do not change the ~/.silc directory's permissions automatically.
2866 Affected file irssi/src/silc/core/clientutil.c.
2868 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Do not cancel the protocol in silc_server_close_connection
2871 it might cause recursion. Now cancelled in the function
2872 silc_server_free_sock_user_data. Affected file silcd/server.c.
2874 * Fixed the silc_server_remove_clients_by_server to regenerate
2875 the channel keys correctly finally. Added also new function
2876 silc_server_remove_clients_channels to actually do it.
2877 Affected file silcd/server.c.
2879 * Fixed the silc_server_new_channel to not crash by giving
2880 wrong router to the new channel. Affected file is
2881 silcd/packet_receive.c.
2883 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2885 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2886 which is given as argument to the silc_client_alloc now.
2887 It can be used to configure the client and set various parameters
2888 that affect the function of the client.
2890 * The USERS command in server did not check whether the channel
2891 is private or secret. Affected file silcd/command.c.
2893 * Added new argument to the USERS command in protocol specification.
2894 The USERS command now can take the channel name as argument
2895 as well. Added support for this in client and server and
2896 updated the protocol specs.
2898 * Completed the GETKEY command in client. It can be now used
2899 to fetch also servers public key not only some clients.
2900 Affected files lib/silcclient/command[_reply].c.
2902 * Added silc_client_get_server to return server entry by the
2903 server name. Affected files lib/silcclient/silcapi.h and
2906 * Redefined the IDENTIFY command in protocol specification to be
2907 more generic. It now can be used to query information about
2908 any entity in the SILC Network, including clients, servers and
2909 channels. The query may be based either the entity's name
2910 or the ID. Added support for this in both client and server.
2912 Affected files silcd/command.c and lib/silcclient/command.c
2913 and command_reply.c.
2915 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2916 the _from_client and _from_server functions. Affected file
2919 * Added silc_client_get_channel_by_id_resolve to the file
2920 lib/silcclient/silcapi.h to resolve channel information by
2921 its ID. Added also silc_client_get_channel_by_id that
2922 does not resolve it from the server.
2924 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2926 * Added SilcServerEntry context into the client library
2927 to represent one server. The INFO command now allocates
2928 these to save the resolved server info. For now on the
2929 client library will also keep information about servers,
2930 connected and resolved with INFO.
2932 The INFO command now allocates the SilcServerEntry context
2933 and saves the server info there. The COMMAND_REPLY in
2934 the INFO now returns the parameters to application in
2935 same order as defined in the protocol specification.
2937 The entries are cached in the client->server_cache.
2939 * The INFO command is now issued after received the Client ID
2940 from the server. Affected file lib/silcclient/client.c.
2942 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2943 to the application as the mode changer might be server.
2944 It is guaranteed that NULL is not returned anymore to the
2945 application. Affected file lib/silcclient/client_notify.c.
2947 The ID Type is now also passed to the application so that
2948 it can check whether the returned entry is SilcClientEntry
2951 Added new function silc_client_get_server_by_id to return
2952 the server entry by ID. Affected files are the
2953 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2955 * Do not create the channel in the Irssi SILC Client when issuing
2956 the JOIN command but when received the sucessful JOIN command
2957 reply. Otherwise the channel might get created even though we
2958 could not join it. The Affected file is
2959 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2961 * Fixed a channel joining bug in router. The router must also
2962 check the channel modes, invite and ban lists etc. when serving
2963 the JOIN command sent by normal server. Affected file is
2964 silcd/command.c. The router now resolves the client's
2965 information from the server who sent the JOIN command if it
2966 does not know it, and processes the JOIN command only after
2969 * Changed the SilcCommandCb to take new argument; void *context2.
2970 Affected file lib/silccore/silccommand.h
2972 The second argument in the command callbacks in the server now
2973 includes the SilcServerCommandReplyContext if the command was
2974 called as pending command callback from the command reply.
2975 Otherwise it is NULL. When called as pending the status of the
2976 command reply will be checked and if it was erronous the
2977 error will be sent to the original sender of the command.
2978 This way the client always receives the error messages even
2979 though the server was actually the one who received the error
2980 when it resent the command to router, for example. Affected
2981 files silcd/command[_reply].[ch].
2983 * Fixed sending WHOWAS command's error message to client if
2984 the requested client could not be found. It was missing.
2987 * Changed the CMODE and CUMODE commands reply arguments in the
2988 protocol specification. The Channel ID is now sent in both
2989 of the commands to identify the channel. Implemented this
2990 new feature to the client and server. Affected files
2991 lib/silcclient/command_reply.c and silcd/command.c.
2993 * Made better checks for invite and ban lists in the JOIN
2994 command in server. Affected file silcd/command.c.
2996 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2998 * The server now performs the incoming host IP/DNS lookup
2999 using the silc_socket_host_lookup and thus does not block
3000 the server anymore. Affected file silcd/server.c.
3002 * Completed the multi-thread support for SILC Scheduler in
3003 the lib/silcutil/silcschedule.c.
3005 * Fixed the configure.in.pre to detect the pthread correctly
3008 * Fixed a deadlock in silc_task_queue_wakeup in the file
3009 lib/silcutil/silctask.c.
3011 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * Added new function silc_schedule_wakeup that is used in
3014 multi-threaded environment to wakeup the main thread's
3015 schduler. It needs to be used when a thread adds a new task
3016 or removes a task from task queues. After waking up, the
3017 scheduler will detect the task queue changes. If threads
3018 support is not compiled in this function has no effect.
3019 Implemented the wakeup mechanism to both Unix and WIN32
3020 systems. Affected files are lib/silcutil/silcschedule.[ch],
3021 lib/silcutil/unix/silcunixschedule.c and the
3022 lib/silcutil/win32/silcwin32schedule.c.
3024 * Added new function silc_task_queue_wakeup to wakeup the
3025 scheduler by the specified task queue. Affected file
3026 lib/silcutil/silctask.[ch].
3028 * The silc_socket_host_lookup_start now wakes up the scheduler
3029 after adding the timeout task. Affected file is
3030 lib/silcutil/silcsockconn.c.
3032 * The silc_socket_host_lookup is synchronous now if the threads
3033 support is not compiled in. However, the callback is still
3034 called asyncronously through the scheduler, anyway. Affected
3035 file lib/silcutil/silcsockconn.c.
3037 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3039 * Added new function silc_socket_host_lookup to perform
3040 asynchronous IP and FQDN lookups for the socket connection.
3041 Affected files lib/silcutil/silcsockconn.[ch].
3043 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3045 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3046 that may or may not compile the mutex support in.
3048 Changed the silc_mutex_alloc interface. It allocates the
3049 mutex now to the sent pointer and returns TRUE or FALSE.
3051 Affected file lib/silcutil/silcmutex.h.
3053 * Wrote the SILC Task Queue interface to support multi-threads.
3054 Affected file lib/silcutil/silctask.[ch].
3056 * Wrote the SILC Scheduler to support multi-threads. Affected
3057 file lib/silcutil/silcschedule.c.
3059 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3061 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3062 in lib/silcutil/win32/.
3064 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Defined SILC Mutex API and SILC Thread API and implemented
3067 them for Unix. Affected files are
3068 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3069 lib/silcutil/unix/silcunixmutex.c and
3070 lib/silcutil/unix/silcunixthread.c.
3072 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3074 * Fixed the silc_server_remove_clients_by_server's channel
3075 key re-generation. The hash table handling was incorrect
3076 and would not work with many channels. Affected file is
3079 * Fixed some memory leaks around the server code.
3081 * Rewrote the silc_server_get_users_on_channel to support IPv6
3082 based Client ID's. Affected file silcd/server.c.
3084 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3085 specification. However, a separate document must be written
3086 to define the detailed signing procedure and the payload
3087 associated with the flag. Defined the flag to the
3088 lib/silccore/silcchannel.h as well.
3090 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3092 * Changed the dynamic tables to static size tables in the
3093 lib/silccrypt/silchmac.c.
3095 * Removed GCC dependencies from the code. A patch by cras.
3097 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3099 * Do not show the error "Error receiving packet bla bla"
3100 in server if it really was not an error (-2 means that reading
3101 is pending). Affected file silcd/server.c.
3103 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3105 * Fixed a possible crash in silc_server_remove_clients_by_server
3106 in silcd/server.c. Fixed there also some memory leaks.
3108 * Fixed the silc_idlist_replace_client_id. It could replace
3109 wrong key in the hash table. Affected file silcd/idlist.c.
3111 * Do not check whether there are global users on the channel
3112 if the channel->global_users is FALSE. Affected functions
3113 silc_server_remove_from_one_channel and
3114 silc_server_remove_from_channels in silcd/server.c. Also,
3115 do not check if the removed client is local as we can be
3116 sure that global client was not removed from the channel
3117 and checking for global users is not needed.
3119 * The silc_server_remove_clients_by_server now re-generates
3120 the channel keys correctly for those channels that had
3121 clients removed from them. Affected file silcd/server.c.
3123 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3125 * Found the reason of random crashes in the server. We weren't
3126 ignoring the SIGPIPE signal (which can be sent in write())
3127 and it crashed the server. Affected file silcd/silcd.c.
3129 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3131 * Assure that sock->user_data is not NULL in the function
3132 silc_server_packet_send in silcd/packet_send.c.
3134 * Disconnect the remote connection if it could not be added
3135 to any ID lists in the server. The affected file is
3138 * Check in silc_server_packet_send[_real/dest] that the
3139 socket is not disconnecting and ignore the data if it is.
3140 Affected file silcd/packet_send.c.
3142 * Define inline to __inline on native WIN32 compilation.
3143 Affected file includes/silcwin32.h.
3145 * Added some explicit type casts for inline code since MSVC
3146 require them. Affected files lib/silcutil/silcbuffer.h,
3147 lib/trq/silcdlist.h and lib/trq/silclist.h.
3149 * Print warning in log files from now on if the packet
3150 decryption fails. Affected file silcd/server.c.
3152 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3154 * Changed the `say' client operation's interface to accept
3155 new `type' argument to indicate the type of the message sent
3156 by the library. The application may filter the library's
3157 messages according the type. The affected file is the
3158 lib/silcclient/silcapi.h.
3160 * Added two new functions to lib/silcclient/silcapi.h:
3161 silc_client_del_client and silc_client_del_client_by_id.
3162 Affected file lib/silcclient/idlist.c.
3164 * Moved the clientincludes.h from includes/ to silc/ and
3165 serverincludes.h from includes/ to silcd/.
3167 * The modes for the CMODE and CUMODE are now passed as
3168 uint32 for application with COMMAND_REPLY. The affected
3169 file is lib/silcclient/command_reply.c.
3171 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3173 * /WHOIS without arguments shows client's own information.
3174 Affected file lib/silcclient/command.c.
3176 * Changed PING to not accept any arguments. The specs
3177 says that client can ping only the connected server so
3178 requiring an argument is not needed. Affected file is
3179 lib/silcclient/command.c.
3181 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3183 * Fixed a fatal bug in private message sending and reception
3184 encryption and decryption when using private message keys.
3185 The implementation was incorrect and did not follow the
3186 specification. It causd that some of the message were
3187 lost since it did not use the sending and receiving keys
3188 as the protocol suggests. This has been fixed and will cause
3189 incompatibilities with older clients when sending private
3190 message encrypted with private message keys. Affected files
3191 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3192 and various other in Irssi SILC Client.
3194 Added `responder' boolean argument to the functions
3195 silc_client_add_private_message_key[_ske] to indicate when
3196 the key is added as responder or initiator of the key
3199 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3201 * Removed the silc_ske_check_version function and created
3202 a SilcSKECheckVersion callback. Added also a function
3203 silc_ske_set_callbacks that is now used to set all SKE
3204 callbacks. The callback functions are not given to
3205 the SKE functions anymore, but this function is used to
3208 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3210 * Added `silc_version' argument to the silc_client_alloc
3211 to define the version of the application for the library.
3212 The library will use the version string to compare it
3213 against the remote host's (usually a server) version
3214 string. Affected file lib/silcclient/silcapi.h
3216 * Added the KE protocol context to Key Agreement context
3217 in client library so that we can abort the SKE if it
3218 is in process when we get timeout. Affected file is
3219 lib/silcclient/client_keyagr.c.
3221 * Do not resolve the client ID forever if it returns in the
3222 first time that such client does not exist. This was done
3223 for example with private message. Affected file is
3224 lib/silcclient/client_prvmsg.c.
3226 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3228 * Do not add regex.h for WIN32. The affected file
3229 includes/silcincludes.h.
3231 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3232 not work yet 100%. It generates the DLL's automatically
3233 when compiling with --with-win32 under cygwin.
3235 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3237 * lib/contrib/regex.c is not compiled on WIN32.
3239 * Added silc_net_get_socket_opt function to the
3240 lib/silcutil/silcnet.h.
3242 * Added includes/silcwin32.h for WIN32 specific includes
3245 * Do not use ptime structure or any of the posix process
3246 functions on WIN32 in lib/silccrypt/silrng.c.
3248 * Added silc_gettimeofday to provide generic function
3249 for struct timeval on all platforms. Added the function
3250 to lib/silcutil/silcutil.h.
3252 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3254 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3255 library as they clearly belong there. As a plus side we
3256 can make the actual socket connection routines platform
3259 Added also new generic function silc_socket_read and
3260 silc_socket_write (that used to be silc_packet_[read/write].
3261 The implementation of these are platform specific.
3263 * Added WIN32 specific routines of silc_socket_[read/write]
3264 to lib/silcutil/win32/silcwin32sockconn.c.
3266 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3268 * Added preliminary support for native WIN32 compilation under
3269 cygwin (using the -mno-cygwin option for GCC) to the
3270 ./configure.in.pre. The --with-win32 now prepares the
3271 compilation for native WIN32.
3273 * Rewrote the SILC Scheduler interface in the file
3274 lib/silcutil/silcschedule.h. The scheduler is now context
3275 based and does not have anymore any global static scheduler.
3276 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3277 and created lib/silcutil/win32 directory for WIN32 based
3280 * Added Unix specific network routines to the
3281 lib/silcutil/unix/silcunixnet.c and the old
3282 lib/silcutil/silcnet.c includes now only generic routines.
3284 Added WIN32 specific network routines to the
3285 lib/silcutil/win32/silcwin32net.c.
3287 * Added Unix specific utility functions from the
3288 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3290 * Added WIN32 SILC Scheduler to the file
3291 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3294 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3296 * Do not handle JOIN notify in the server if the target client
3297 is not registered (idata->registered == FALSE). The affected
3298 file is silcd/packet_receive.c.
3300 * Update the nickrec->founder in event_cumode in the Irssi SILC
3301 client. Affected file irssi/src/silc/core/silc-channels.c.
3303 * Fixed the CUMODE_CHANGE notify handling in the server when
3304 server and router are announcing their clients on channels.
3305 Now the mode changes are saved and notified correctly. The
3306 affected file is /silcd/packet_receive.c.
3308 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3309 They really did not replace the cache entry in the ID Cache.
3310 Now they do that. Affected file silcd/idlist.c.
3312 * Fixed the KICK notify handling in the Irssi SILC client to
3313 update the channel records so that the kicked client does not
3314 appear to be on the channel. The affected file is
3315 irssi/src/silc/core/silc-channels.c.
3317 * Always update the conn->current_channel when executing command
3318 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3320 * Fixed the KILL notify handling in Irssi SILC client to remove
3321 the killed client on all channels.
3323 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Fixed the silc_parse_command_line to remove extra spaces
3326 from the start and end of the arguments. Affected file is
3327 lib/silcutil/silcutil.c.
3329 * Cancel and free any active protocol in the function
3330 silc_server_close_connection. Affected file silcd/server.c.
3332 * Cancel and free any active protocol in the function
3333 silc_client_close_connction. Affected file is
3334 lib/silcclient/client.c.
3336 * Do not execute the KILL command for clients that are in
3337 history (ie. they are not in the network). Affected file is
3340 * Fixed KILL notify handling, client does not crash anymore.
3341 Affected file irssi/src/silc/core/silc-channels.c.
3343 * Reduced the default packet buffer size from 2048 to 1024 in
3344 lib/silccore/silcpacket.c.
3346 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3347 counter to the SKE context that is incresed when the SKE library
3348 performs async operation outside the library. If the outside
3349 process frees the SKE context and FREED status will be set
3350 and the library will detect after the sync operation that the
3351 libary is freed. The affected files are
3352 lib/silcske/silcske[_status].[ch].
3354 * Resolve the client entry information in the function
3355 silc_client_channel_message to assure that NULL pointer is not
3356 passed as client entry to the application. */
3358 * Fixed the task timeout calculation to assure that there is
3359 never negative timeouts. The affected file is
3360 lib/silcutil/silcschedule.c.
3362 * Fixed the channel user mode notification sending in server.
3363 It was sent point-to-point to the router (or to server by router)
3364 but it needs to be destined to a channel. The routines now
3365 supports sending the channel user mode notifys to the channels
3366 when announcing clients and channels. Affected files are
3367 silcd/server.c and silcd/packet_receive.c.
3369 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3370 It did not actually replace the old channel entry in the cache.
3371 Affected file lib/silcclient/client_notify.c.
3373 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3375 * Fixed a possible crash in silc_packet_send_prepare. It now
3376 assures always that there is enough space in the buffer and
3377 at the tail area of the buffer (for MAC).
3379 Fixed the inbound buffer reallocation in silc_packet_read.
3380 It was old code and did not handle the reallocation correctly.
3383 The affected file is lib/silccore/silcpacket.c.
3385 * Fixed buffer overflow in silc_parse_nickname in the file
3386 lib/silcutil/silcutil.c.
3388 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * make install generates new server keys only if there is not
3393 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3396 Added check that if the NOREPLY is set then we will not send
3397 the away message. This avoids infinite loop of away messages
3398 if both clients are away. The affected file is
3399 lib/silcclient/client_prvmsg.c.
3401 * Fixed client crash if /NICK was given without arguments.
3402 Affected file lib/silcclient/command.c.
3404 * Server does not send the invite list in INVITE command back
3405 to the client if the list was not altered. Added this notion
3406 to the protocol spec as well. Affected file silcd/command.c.
3408 Fixed possible crash in INVITE command by checking the
3409 value of silc_server_get_client_route command.
3411 * Fixed the INVITE notify type handling. The arguments are now
3412 taken in correct order and client does not crash. The affected
3413 file is irssi/src/silc/core/silc-channels.c.
3415 Removed the "Inviting xxx to channel" message from the
3416 client library away and let the application handle it.
3417 Affected file lib/silcclient/command.c. Added that message
3418 to Irssi SILC client's message formats.
3420 * Fixed CMODE command crash in client. It now checks the
3421 amount of arguments correctly and does not crash. The affected
3422 file is lib/silcclient/command.c.
3424 * Do not create new channel automatically in silc_channels_join
3425 but check whether the channel by that name already exists.
3426 Affected file irssi/silc/core/silc-channels.c.
3428 * Do not send the SERVER_SIGNOFF to router if the disconnected
3429 entity was the router. Affected file silcd/server.c.
3431 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3432 SILC client as it was missing from there.
3434 Added the handling of the KICK notify to the Irssi SILC client
3435 as it was missing. Added "you have been kicked" message to
3436 Irssi SILC client's message modules formats.
3438 Added the handing of the KILL notify to the Irssi SILC client
3439 as it was missing. Added the kill message module formats
3442 The affected file is irssi/src/silc/core/silc-channels.c.
3444 * The router did not save the channel mode the server announced.
3445 Affected file silcd/packet_receive.c.
3447 * Fixed a possible crash in INFO command in server. If the
3448 server did not provide the server info it crashed. Affected
3449 file silcd/command.c.
3451 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3453 * Fixed the GETKEY command in the server to check also the
3454 global list. Otherwise the GETKEY would not work correctly
3455 in normal SILC server. Affected file silcd/command.c.
3457 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * Fixed GETKEY crash, it crashed if the command did not succseed.
3461 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3464 is now real and not just an macro interface to GMP.
3466 Removed the entire GMP from the source tree and imported new
3467 NSS MPI library instead. Reason for removing GMP is that it is
3468 extremely large and compiles extremely slow. The NSS MPI
3469 is only a few files and compiles in less than 10 seconds.
3470 The speed is also about the same as GMP. The MPI is imported
3471 to lib/silcmath/mpi.
3473 If the system has GMP installed we will still use the GMP.
3474 If it is not then the NSS MPI will be compiled.
3476 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Merged a long nickname (127 characters long) crash bugfix from
3479 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3481 * Merged a freed memory reference bugfix from Irssi CVS tree.
3482 Affected file irssi/src/core/commands.c.
3484 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Added the server's public key sving and verification to the
3487 server when performing the SKE. This was missing and the
3488 remote server's (or router's) public key was accepted without
3489 checking whether we have it previously or trust it at all.
3490 Affected file silcd/protocol.c.
3492 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3494 * Check in the silc_server_timeout_remote if protocol is active
3495 and make sure that the protocol's final callback is called so
3496 that all memory if freed. Affected file silcd/server.c.
3498 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * silc_server_whois_send_reply crashed the server if the nickname
3501 was 127 characters long. Affected file silcd/command.c.
3503 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Added sanity check to the silc_server_new_client. If the hostname
3506 is provided inside username then check that the provided hostname
3507 really is the same as the resolved one. If the hostname was not
3508 resolved then check it from the public key. Affected file is
3509 silcd/packet_receive.c.
3511 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3512 if the server disconnected us and the connection is not valid
3513 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3515 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3516 the library to the lib/silcutil/silcutil.[ch].
3518 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3520 * Close log file after open. Affected file
3521 lib/silcutil/silclog.c.
3523 * Check whether sock == NULL in silc_client_send_packet and return
3524 if it is. Affected file lib/silcclient/silcclient.c.
3526 * Check rec->entry == NULL in the Irssi SILC Client before
3527 sending the channel message. Affecte file is
3528 irssi/src/silc/core/silc-servers.c.
3530 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * Merged a splitted window bugfix from Irssi CVS tree. The
3533 affected file is irssi/src/fe-text/textbuffer-view.c.
3535 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3536 It did not print nickname.
3538 * Improved the distributions system a bit.
3540 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3543 irssi/src/fe-text/gui-window.c.
3545 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3546 to in-active server. The affected file is
3547 irssi/src/silc/core/client_ops.c.
3549 * Resolve the client in USERS command reply if the entry does
3550 not have username resolved. The affected file is
3551 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3552 command to WHOIS command to really resolve stuff. The USERS
3553 is not used any more in any critical section so WHOIS can
3554 be used even though it might be slower than IDENTIFY.
3556 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3559 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * Changed the protocol API a bit more consistent in the
3562 lib/silccore/silcprotocol.[ch].
3564 * Changed the following headers to ROBODoc format:
3566 lib/silccore/silcpayload.h
3567 lib/silccore/silcprotocol.h
3568 lib/silccore/silcsockconn.h
3570 All core library headers are now formatted.
3572 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Fixed a bug in Irssi SILC client; do not show that you are
3575 server/router operator if you really are not. Affected file is
3576 irssi/src/silc/core/client_ops.c.
3578 * Renamed silc_command_free_payload to silc_command_payload_free.
3579 Affected file lib/silccore/silccommand.h
3581 * Added silcmath.h to include the prototoypes of various routines
3582 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3585 * Changed the following headers to ROBODoc format:
3587 lib/silccore/silcchannel.h
3588 lib/silccore/silccommand.h
3589 lib/silccore/silcid.h
3590 lib/silccore/silcidcache.h
3591 lib/silccore/silcmode.h
3592 lib/silccore/silcnotify.h
3593 lib/silccore/silcpacket.h
3594 lib/silcmath/silcmath.h
3596 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Added checking to the server code not to start the server if
3599 ciphers and stuff are not configured properly. Affected files
3600 silcd/serverconfig.[h] and silcd/server.c.
3602 * Changed the layout of the header files of the public interfaces
3603 in the SILC libraries. The new layout supports ROBODoc
3604 documentation tool (and some others) so that it is easy to create
3605 a library reference manual. All the other headers and source
3606 code must still follow the CodingStyle document. Also source
3607 code must not include these ROBODoc stuffs, only the headers.
3608 Furthermore, all public interface headers must now be named
3609 by using `silc' prefix, example: silcapi.h, silccipher.h.
3610 Some files were renamed due to this. All the other headers
3611 must not be used as public interfaces. I will update the
3612 CodingStyle document later. Changed following headers, so far:
3614 lib/silcclient/silcapi.h
3615 lib/silccore/silcauth.h
3616 lib/silccore/silcprivate.h
3617 lib/silccrypt/silcdh.h
3619 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3623 * Removed silc_client_packet_send_flush from the client library
3624 as it is not needed. Affected file lib/silcclient/client.[ch].
3626 * Added printing of message of unresolved authentication method
3627 to the Irssi SILC client. Added it to the module formats.
3628 Removed the same message from the client library.
3630 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3632 * Added new distribution feature, DISTLABEL. Every distribution
3633 can define own preprocessor label that can be used in the
3634 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3635 file distributions, acconfig.h.pre and prepare.
3637 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3639 * Added Makefile.defines_int to include the actual definitions
3640 for Makefile.defines.in. Tested the new distribution system,
3641 created distributions and tested installation.
3643 * Added AWAY message printing to the Irssi SILC client. Added
3644 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3646 * Added SCONNECT command to call the SILC's CONNECT command.
3647 Cannot use CONNECT directly since Irssi uses that internally.
3648 Affected file irssi/src/silc/core/silc-servers.c.
3650 Added ACTION local command. It is same as ME command but takes
3651 the channel as mandatory argument.
3653 Rewrote some of the Irssi's help files to suite for SILC
3656 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Added Makefile.defines[.in] that should for now on be included
3659 in all Makefile.am file in the source tree. That file includes
3660 all common compilation definitions for SILC source tree.
3662 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Minor changes to the ./prepare script to change the package
3665 name according the distribution name to the configure.in.
3667 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3669 * Created new distribution system. Added file `distributions'
3670 that defines all the distributions that can be created out of
3671 the SILC source tree. The ./prepare script now reads that
3672 file to determine how to prepare the distributions. The
3673 first argument to the ./prepare is the name of the distribution
3674 and second is the version of the distribution. If given
3675 without arguments it creates the default (toolkit) distribution
3676 with the default version (defined in ./prepare).
3678 All Makefile.am files that are subject to the distributions
3679 are now named as Makefile.am.pre. These are ./Makefile.am
3680 and lib/Makefile.am. Others may be changed later.
3682 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Added invite list, ban list, some key management and connection
3685 error message printing to module formats in the Irssi SILC client.
3687 * Added new silc_client_set_away_message to set the away message
3688 that is back to the person who sent private message. The
3689 affected file lib/silcclient/silcapi.h and the
3690 lib/silcclient/client_prvmsg.c.
3692 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3694 * Fixed the private message sending in the Irssi SILC client,
3695 added local command KEY to the Irssi SILC client.
3697 Added key management and key agreement message formats to the
3698 irssi/src/fe-common/silc/module-formats.[ch].
3700 Added USERS (alias WHO) printing, server/router operator
3701 indication and LIST command printing to the module formats.
3703 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Fixed channel joining notify handling, cumode notify handling
3706 from Irssi SILC client.
3708 * Added SILC specific module-formats to the Irssi SILC client so
3709 that SILC specific message hilighting, colors etc is possible.
3710 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3712 Added channel mode, channel user mode, actions, notices,
3713 whois and whowas printing to the the module-formats.c.
3715 * Fixed a bug in channel deletion in the server. The channel
3716 is not left to the cache even if the channel founder auth mode
3717 is set when there are no users anymore on the channel. Affected
3718 file silcd/server.c.
3720 * The silc_net_localhost now resolves the entire hostname including
3721 the domain name. Affected file lib/silcutil/silcnet.c.
3723 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3725 * Changed the ask_passphrase client operation to be ascynchronous.
3726 It has now a completion callback and a context that the
3727 application must call after it has got the passphrase from
3728 the user. Affected files lib/silcclient/silcapi.h,
3729 lib/silcclient/protocol.c, lib/silcclient/command.c and
3732 Added SilcAskPassphrase callback that the application calls
3733 to deliver the passphrase to the library.
3735 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3736 The public key verification and especially a certificate
3737 verification is asynchronous procedure.
3739 Added new SILC_SKE_STATUS_PENDING status to indicate the
3740 request is pending and a callback will be called to finalize
3743 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3744 indicate that remote end did not send its public key (or
3745 certificate), even though we require it. Added check for this
3746 condition in the SKE. This was a security bug, now fixed.
3748 Defined new SilcSKEVerifyCbCompletion callback that is called
3749 when the verification process is completed.
3751 The affected files lib/silcske/silcske_status.h and
3752 lib/silcske/silcske.[ch].
3754 * Changed the verify_public_key client operation to be async
3755 as well. Defined SilcVerifyPublicKey callback that is used to
3756 indicate the success of the public key verification process.
3758 Changed the server and client to use the new async client
3761 * Changed the Irssi SILC client's internal scheduler to be called
3762 twice as many times as it used to be. As a result the client
3763 should be a bit faster now. Affected file is
3764 irssi/src/silc/core/silc-core.c.
3766 * Added support to Irssi SILC client of asynchronous public key
3767 verification and passphrase inquiry. Affected file is
3768 irssi/src/silc/core/silc-core.c.
3770 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3772 * Do not say "You have left channel %s" in client library.
3773 Moved it to the application. Affected files are
3774 lib/silcclient/command.c and silc/client_ops.c.
3776 * Fixed silc_client_get_clients. Command context was not
3777 duplicated and was freed memory in the callback. Affected
3778 file lib/silcclient/idlist.c.
3780 * Do not say "you are now talking..." on JOIN command in the
3781 client library. The appliation must handle it.
3783 * Do not say ".. changed topic to" in command reply in the
3784 client libary. The application must handle it.
3786 * Fixed TOPIC command sending in the client library.
3788 * Fixed a memory leak in silc_client_command_free in the file
3789 lib/silcclient/command.c.
3791 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Imported a modified version of Irssi client to the source tree.
3794 The Irssi will be used to create a new client called
3795 Irssi SILC. Imported to irssi/.
3797 Added silc_core_init_finish function to the Irssi. Affected
3798 file irssi/configure.in.
3800 A lot changes in the Makefile.ams around the irssi tree.
3802 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Do not rehash if the new size is same as the old size of the
3805 hash table, in the silc_hash_table_rehash*. The affected file
3806 lib/silcutil/silchashtable.c.
3808 * Replaced hash_table_del_by_context calls from the server
3809 (when channel->user_list and client->channels) to the
3810 hash_table_del as it is sufficient and faster.
3812 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3814 * Added silc_hash_table_list, silc_hash_table_get and the
3815 SilcHashTableList structure to provide an alternative way to
3816 traverse the hash table. The affected files are
3817 lib/silcutil/silchashtable.[ch].
3819 * Changed the server's idlist routines to use the hash table
3820 routines to optimize the code.
3822 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Replaced the client entry's `channel' list and channel entry's
3825 `user_list' list to hash tables for optimized lookup. Changed
3826 the code to use the hash table interface around the code.
3827 Affected file lib/silcd/idlist.[ch].
3829 * Added `auto_rehash' boolean argument to the function
3830 silc_hash_table_alloc to indicate whether the hash table should
3831 auto-rehash when it thinks is appropriate time. It will
3832 increase the hash table size if the there is twice as much
3833 entries in the table than the size of the table, and will
3834 decrease the size if there are twice as less entries than
3835 the size of the table.
3837 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3841 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * silc_idcache_purge_by_context deletes the entry now by context
3844 as it is supposed to do. Affected file lib/silccore/idcache.c.
3846 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3847 client is not anymore valid (WHOWAS givens the info) and not
3848 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3850 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Removed the `data' and `data_len' arguments from the ID Cache
3853 interfaces and added `name' argument. ID Cache does not handle
3854 anymore the binary data only a names associated with given ID.
3856 * When hashing a Client ID with silc_hash_id the entire ID is
3857 not hashed anymore, instead only the hash of the Client ID is
3858 hashed. This way we can access the Client ID from the cache
3859 with Client ID but with the hash of the ID (which is a hash of
3860 the nickname) as well without any difference in performance.
3862 Added also silc_idcache_find_by_id_one_ext to do one on one
3863 searching when we have the actual ID. Added also function
3864 silc_hash_client_id_compare. The affected files are
3865 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3867 * When hashing the name associated with a ID it is always done
3868 in lowercase. This way we can access the cache without worrying
3869 about case-sensitivity, even though, for example nicknames are
3872 * Fixed a bug in server with channel message sending. It put
3873 wrong ID type as destination ID. The affected file
3874 silcd/packet_send.c.
3876 * silc_idcache_del_by_context now deletes from all hash tables
3877 by context. Affected file lib/silccore/idcache.c.
3879 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Changed the client library to use the new ID Cache interface.
3882 Changes around the source tree.
3884 * Added silc_hash_table_rehash_ext to rehash with specific
3885 hash function. Affected file lib/silcutil/silchashtable.[ch].
3887 * Added silc_hash_string_compare to compare two strings in the
3888 hash table. Affected file lib/silcutil/silcutil.[ch].
3890 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Added new function silc_idcache_del_by_context into the
3893 lib/silccore/idcache.[ch].
3895 * Changed the server's ID list routines to use the new ID Cache
3896 interface. Changes around the source tree.
3898 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * Added silc_hash_table_del[_by_context]_ext functions in to the
3901 lib/silcutil/silchashtable.[ch].
3903 Removed silc_hash_table_find_all* routines and added new
3904 silc_hash_table_find_foreach to replace them.
3906 Added silc_hash_table_replace_ext function as extended
3907 replacing function. Separated the simple hash table interface
3908 from the extended hash table interface in the file
3909 lib/silcutil/silchashtable.h.
3911 * Fixed minor bugs and changed it to use some of the new
3912 hash table functions in lib/silccore/idcache.c
3914 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3916 * Added new function silc_hash_table_find_all to return all keys
3917 in the hash table by the specified key. As the hash table is
3918 collision resistant it also makes it possible to have several
3919 duplicate keys in the hash table. This function may be used to
3920 find all of the keys from the hash.
3922 Added user_context arguments to the SilcHashFunction,
3923 SilcHashCompare and SilcHashDestructor to deliver user specified
3926 Added new fuctions silc_hash_table_find[_all]_ext to do
3927 extended lookup with specified hash and compare functions and
3928 specified user contexts.
3930 Added new function silc_hash_table_add_ext to add the key
3931 with specified hash function and user context.
3933 Added new function silc_hash_table_foreach to traverse all
3934 entrys in the hash table. Added SilcHashForeach callback
3937 Added new function silc_hash_table_del_by_context to delete
3938 the entry only if the context associated with the key matches.
3940 Affected files are lib/silcutil/silchashtable.[ch].
3942 * Removed silc_hash_[server/client/channel]_id and added just
3943 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3944 silc_hash_id_compare to compare two ID's using as the hash table
3945 comparison function. Added also silc_hash_data to hash
3946 binary data and silc_hash_data_compare to compare it.
3948 * Removed silc_idlist_find_client_by_hash as it is not needed
3949 anymore. Affected file silcd/idlist.[ch].
3951 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3952 to use internally the SilcHashTable. The new ID Cache is a lot
3953 faster than the old one. Some of the ID Cache interface was also
3954 rewritten and obsolete and stupid functions were removed.
3956 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * Added entry_count field to the SilcHashTable to keep the number
3959 of the entries in the table. Implemented the function
3960 silc_hash_table_rehash. Added new function
3961 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3963 Fixed a minor bug in silc_hash_table_free.
3965 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3966 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3967 into the lib/silcutil/silcutil.[ch].
3969 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Implemented a collision resistant hash table into the
3972 lib/silcutil/silchashtable[ch]. See the header and the source
3973 for the SilcHashTable API.
3975 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3977 * Merged dotconf version 1.0.2 into lib/dotconf.
3979 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Do not compile anything in lib/silcsim/* if the SIM support
3982 is not enabled. The tree should now compile without problems
3985 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Compiled the SILC under cygwin. Compiled and tested briefly
3988 without problems. More tests needed. The SIMs didn't compile
3991 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3993 * Fixed possible crash in silc_get_username in the
3994 lib/silcutil/silcutil.c.
3996 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Fixed a va_arg in silc/client_ops.c.
4000 * Oops, RC5 routines were named AES and caused some problems
4001 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4003 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Added new SilcIDIP structure into the lib/silccore/id.h and
4006 replaced the old `ip' fields from all SILC ID's to that type.
4007 This is a step towards IPv6 support.
4009 The silc_id_get_len takes now the ID as an extra argument.
4010 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4011 both IPv4 and IPv6 based ID's.
4013 The affected files are lib/silccore/id.[ch] and other files
4014 around the tree using these routines.
4016 * Removed the ID length arguments in server from various
4017 silc_server_send_notify_* routines -> they are not needed
4020 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Fixed memory leak in silc_encode_pem_file in the file
4023 lib/silcutil/silcutil.c.
4025 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Check minor version as well in the SKE. Affected files are
4028 silcd/protocol.c and lib/silcclient/protocol.c.
4030 * Added --identifier option to the server so that an identifier
4031 can be when creating the public key for the server. Affected
4032 file is silcd/silcd.c.
4034 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4035 lib/silccrypt/silcpkcs.c.
4037 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4039 * Register default ciphers and stuff when using -C option with
4040 the server. Affected file sildc/silcd.c.
4042 * Put back the servers public key filename format, it is better
4043 than the new one. For now, the client keys are saved with the
4044 new filename format. The affected file silc/client_ops.c.
4046 * Implemented the Cipher API for the rest of the ciphers that
4047 did not implement it or implemented it the wrong way.
4049 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Register default ciphers and stuff when using the -S option
4052 in the client. Affected file silc/silc.c. Same also when
4053 creating new key pair with -C option.
4055 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4057 * Fixed the silc_verify_public_key client operation function to
4058 save the public keys differently. The fingerprint is now
4059 used as filename and not the hostname. This way also the
4060 client keys are saved uniquely and not with hostnames. The
4061 affected file is silc/client_ops.c.
4063 * Trimmed the silc_hash_fingerprint function to remove extra
4064 whitespaces from the end of the fingerprint. The affected
4065 file is lib/silccrypt/silchash.c.
4069 * Added silc_cipher_register_default function to register all
4070 default ciphers. It can be used when configuration files
4071 does not exist and the application does not want any specific
4072 ciphers in any specific order.
4074 The SilcDList is now used as silc_cipher_list dynamically
4075 allocated cipher list. Removed the static list all together
4076 and now all ciphers must be allocated to the dynamic list.
4077 The silc_cipher_alloc routine was changed to check only the
4080 All silc_cipher_* routines that used to return int returns
4083 The affected files lib/silccrypt/silccrypt.[ch].
4085 * The same thing was done to silc_hash_* as for silc_cipher_*
4086 routines. Affected files lib/silccrypt/silchash.[ch].
4088 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4089 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4090 Added also silc_pkcs_[un]register[_default] functions.
4091 Removed the data_context from the PKCS API.
4093 * Added silc_hmac_register_default function to register default
4094 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4095 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4096 to unregister all hmacs at once.
4098 * Register the default ciphers, hash functions, PKCSs and HMACs
4099 if client's configuration file does not exist. The affected
4102 * The client did not load the hash functions from the SIM
4103 modules at all. Added support for this. Affected file is
4104 silc/clientconfig.c.
4106 * When decoding public key with silc_pkcs_public_key_decode, check
4107 the supported algorithm only if PKCS are registered. Affected
4108 file lib/silccrypt/silcpkcs.c. The same was done with the
4109 silc_pkcs_private_key_decode.
4111 * Fixed the SILC List routines to keep the list always in order.
4112 It used to change the list's order when traversing the list but
4113 not it preserves the order. Affected file lib/trq/silclist.h.
4115 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4117 * Added the client library to use the SilcSocketConnection's
4118 reference counter (by silc_socket_dup) to prevent the bug that
4119 the socket object may be freed underneath async operation.
4121 * The name resolv library checking fixes in the configure.in.pre.
4124 * Created new version of the protocol drafts for future
4125 development. The -03 drafts are the ones that will be changed
4126 in the trunk now and the -02 will remain as they are.
4128 * Send list of CUMODE notifys to the router when announcing
4129 the channel users to the router. Affected file silcd/server.c.
4130 If the router receiving channel founder CUMODE for a channel
4131 that already has channel founder it will send CUMODE notify
4132 to the sender to remove the channel founder rights from the
4133 announced client. Affected file silcd/packet_receive.c.
4135 * The CUMODE notify may now use Server ID as well as the entity
4136 who changes the mode. Updated protocool specs.
4138 * Updated INSTALL and README files.
4140 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4142 * New web pages in the http://silc.pspt.fi. The pages was
4147 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Implemented the [DenyConnectin] config section in the server.
4150 Added silc_server_config_denied_conn to check whether incoming
4151 connection is denied. Affected file silcd/serverconfig.[ch].
4153 * Do not check the ports when checking the incoming configuration
4154 data if the port is 0, meaning any. Affected file is
4155 silcd/serverconfig.c.
4157 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Fixed buffer overflow in silc_string_compare in the file
4160 lib/silcutil/silcutil.c.
4162 * Fixed double free in silc_server_command_leave in the file
4165 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Fixed the version checking in the server. Affected file is
4170 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Fixed the configuration data fetching when accepting new
4173 connections in the server. Affected file silcd/server.c.
4175 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Added `sender_entry' argument to the function
4178 silc_server_packet_relay_to_channel so that we can check
4179 whether some destination actually belongs to the same route
4180 the sender belongs (ie, we must not resend the packet to the
4181 sender). Affected file silcd/packet_send.[ch].
4183 * Added `servername' field to the SilcClientEntry in the server
4184 to hold the name of the server where client is from. Affected
4185 file is silcd/idlist.h.
4187 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Moved the channel message encrypting in the router betwen
4190 router connections from silc_server_channel_message to the
4191 silc_server_packet_relay_to_channel since we want to check
4192 whether we have anybody channel before encrypting anything.
4193 Affected files silcd/packet_[receive/send].c.
4195 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4197 * Fixed the [AdminConnection] server config section to support
4198 multiple entries. Affected file silcd/serverconfig.c.
4200 * Added support into the server to check the validity of the
4201 incoming connection before executing any KE or authentication
4204 * The connection configuration is now saved to the KE and
4205 connection auth protocol contexts and not fetched anymore in
4206 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4208 * The local hosts listenning address and port is also resolved
4209 now when starting the server. We want to have the socket object
4210 to include the real address and port for the listener. Added
4211 new function silc_net_check_local_by_sock into the files
4212 lib/silcutil/silcnet.[ch].
4214 * Fixed a broadcast bug in server -> do not broadcast if we
4217 * Fixed a routing bug. Do not route broadcast packets ever.
4218 Broadcast packets must be processed always and not routed since
4219 they may be destined to some other host than yourself and thus
4220 would get routed without no good reason. Affected file is
4223 * Added function silc_server_config_is_primary_route to check
4224 whether primary router connection has been configured (a router
4225 configuration that we are initiating). If there is not, we
4226 will assume that there is only two routers in the SILC network
4227 and we will use the incoming router connection as our primary
4228 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4230 * Changed the order of the broadcasting. Broadcast _after_ the
4231 packet has been processed not before. Affected file is
4234 * Fixed a [ClientConnection] parsing bug. The port was never
4235 parsed correctly thus resulting to port 0. Affected file
4236 silcd/serverconfig.c.
4238 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4239 argument and did not set the broadcast packet flag. Affected
4240 file silcd/packet_send.c. Fixed same bug in the function
4241 silc_server_send_notify as well.
4243 * If we receive NEW_ID packet for our own ID in the server, ignore
4246 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * Removed the nickname from the Private Message Payload.
4251 Updated the code and the protocol specs.
4253 * Updated protocol specs for submitting to the IETF.
4255 * Tweaked the Random Number Generator a bit. Affected file
4256 lib/silccrypt/silcrng.c. Exported a new function
4257 silc_rng_[global]_add_noise which can be used to add more
4260 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Do not parse packets with different timeout when protocol
4263 is active -> may cause problem with rekey. Affected file
4266 * When server receives signoff notify it must not create
4267 new channel key if the client is on any channels since the
4268 sender of the signoff notify will create it.
4270 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Added printing of error messages during SKE protocol from the
4273 failure packet sent by server during SKE. Affected file
4276 * Removed the client's failure_callback handling with timeout
4277 and handle it immediately when received.
4279 * The SKE library returned wrong type in SUCCESS and FAILURE
4280 packets. They must be 32 bit MSB not 16 bit MSB.
4282 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Ok, rewrote the logic of the re-key and now it seems to work.
4285 I tested it on high traffic with frequent re-keys without
4286 problems. Added hmac_receive (and renamed hmac to hmac_send)
4287 in SilcClientConnection in lib/silcclient/client.h and
4288 in SilcIDListData in silcd/idlist.h. Also, removed the
4289 SilcPacketParserContext's cipher and hmac fields as they are
4290 not needed anymore and actually caused some problems when
4291 the ciphers and hmac's changed underneath the packet parser.
4293 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * If re-key protocol is active then process the incoming packets
4296 synchronously since we must assure that icoming packets encrypted
4297 with the old key is processed before the new keys is set to
4298 use. This is true other packets than for REKEY packets.
4299 Affected file silcd/server.c. The same was done to client library
4300 as well, affected file lib/silcclient/client.c.
4302 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Fixed bug in client and server to accept the force send if
4305 the packet is send from silc_[server/client]_packet_process
4306 function. Otherwise the packets are never delivered, oops.
4308 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Disable force sending of packets when REKEY protocol is active.
4311 We must assure that no packet is sent directly when rekey is
4312 performed. All packets must be sent through packet queue.
4313 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4314 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4315 function is silc_[server/client]_packet_send_real to check
4318 * Replaced the SIM paths from example config files to
4319 /usr/local/modules. Also, make install creates now
4320 /usr/local/silc/logs directory to hold all the SILC server
4323 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Made the configure.in.pre work on Solaris. Patch by salo.
4327 * Made all ciphers compatible with non-x86 machines. Defined
4328 CBC mode macros into lib/silccrypt/ciphers_def.h.
4330 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * Fixed the make install.
4334 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4336 * When MAC computation fails the silc_packet_decrypt returned 0
4337 even though it was supposed to return -1. Fixed this. The
4338 affected file is lib/silccore/silcpacket.c.
4340 * Do not replace the config files in /etc/silc (in make install)
4341 if they already exist. Affected file ./Makefile.am.
4343 * Do not send re-key packets immediately but through packet queue.
4344 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4346 * Changed silc_net_check_host_by_sock to return FALSE if the
4347 IP/DNS could not be resolved. Though, it returns the IP address
4348 now even if it could not resolve it (but returns also FALSE).
4349 Affected file lib/silcutil/silcnet.[ch].
4351 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Added silc_pkcs_decode_identifier to decode the public key's
4354 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4355 Added also silc_pkcs_free_identifier. Added also new context
4356 SilcPublicKeyIdentifier.
4358 * Added -S option to the silc client. It is used to dump the
4359 contents of the specified public key file.
4361 * Changed the PKCS api to return the public key length when
4362 setting the public key.
4364 * Fixed a fatal bug in the public and private key file loading.
4365 Affected file lib/silccrypt/silcpkcs.c.
4367 * Execute the packet parsing for client with zero (0) timeout
4368 if the protocol is active. Affected file silcd/server.c.
4370 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Made the key generation options to the silcd program. Added
4373 -C option, equivalent to client's option.
4375 * Added new [ServerKeys] config section to the server. It
4376 configures the server's public and private key.
4378 * Defined generic Public Key Payload into the protocol
4379 specification to send specific type of public keys and
4382 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4383 public key or certificate.
4385 * Implemented the GETKEY command to the server and to the
4386 client library and on user interface.
4388 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Made preliminary `make install' work.
4392 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Added SilcServerRekey context into silcd/idlist.h.
4396 * Added the PFS support as defined in the specification to the
4397 SKE protocol. Affected files lib/silcske/*.c.
4399 * Added `ske_group' field to the SilcServerRekey context to hold
4400 the number of the SKE group that is used with PFS in re-key.
4401 Affected file silcd/idlist.h.
4403 * Added PFS re-key support to the server. Affected file is
4406 * Added silc_protocol_cancel to cancel execution of the next
4407 state of the protocol. Affected file is
4408 lib/silccore/silcprotocol.[ch].
4410 * Added the re-key support with and without PFS to the client
4411 library. Re-key is performed once in an hour, by default.
4413 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4414 Added silc_client_rekey_callback and silc_client_rekey_final.
4415 Affected files are lib/silcclient/protocol.[ch] and
4416 lib/silcclient/client.[ch].
4418 * Removed the `hmac_key' and `hmac_key_len' fields from the
4419 SilcClientConnection structure; not needed. Affected file is
4420 lib/silcclient/client.h.
4424 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Do not ask whether user wants to use the negotiated private key
4427 for private messages, just use it. Affected file is
4428 silc/local_command.c.
4430 * Added `send_enc_key' and `enc_key_len' fields to the
4431 SilcIDListData structure since they are needed in the re-key
4432 phase. Affected file is silcd/idlist.[ch].
4434 * Implemented the simple re-key protocol into the server.
4435 Affected files silcd/server.c and silcd/protocol.[ch]. The
4436 re-key will be performed once in an hour, by default.
4438 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4439 Added silc_server_rekey, silc_server_rekey_callback and
4440 silc_server_rekey_final.
4442 * Removed Tunneled flag from the protocol. Updated the code
4443 and the specifications.
4445 * Adde `pfs' field to the SilcIDListData to indicate whether
4446 the PFS is to be performed in the re-key. Affected file is
4449 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4452 int64 of at least the xintXX size. If void * is less that 4
4453 bytes uint32 * will be used. Defined bool as boolean.
4455 * Changed _ALL_ unsigned long and unsigned int to uint32,
4456 unsgined short to uint16 in the source tree.
4458 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4459 not handle clients that has entry->data.registered == FALSE.
4460 They are not in the network anymore. Affected file is
4463 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4465 * Implemented the sending of the SERVER_SIGNOFF notify in the
4466 server. Affected file is silcd/server.c.
4468 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4469 Added also silc_notify_payload_encode_args into the
4470 lib/silccore/silcnotify.[ch].
4472 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4473 Affected file silcd/packet_receive.c.
4475 * Implemented the SERVER_SIGNOFF notify handling in the client
4476 library. Affected file lib/silcclient/client_notify.c. Also,
4477 implemnted the printing of the SERVER_SIGNOFF info to the
4478 application. Affected file silc/client_ops.c.
4480 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4481 if the deleting was successful. Affected file silcd/idlist.[ch].
4483 * Added support for public key authentication in the connection
4484 authentication protocol in the client library. Affected file
4485 lib/silcclient/protocol.c.
4487 * Changed the server's silc_idlist_get_clients_by_* interface
4488 to support already allocated array so that new entries may be
4489 added to pre-allocated array. Affected file silcd/idlist.[ch].
4490 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4491 and command replies.
4493 * All command reply functions in the server now calls the
4494 pending command callback even if error occured. This way the
4495 error will be delivered to the client as well. Affected files
4496 silcd/command.c and silcd/command_reply.c.
4498 * Fixed INFO command to return local server's info if no server
4499 was provided. Affected file lib/silcclient/command.c.
4501 * Removed RESTART command for good. Updated the code and the
4504 * Rewrote parts of the task system. It is a bit simpler now.
4505 Removed unsued task priorities. The affected files are
4506 lib/silcutil/silctask.[ch].
4508 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Moved the USERS printing from the library to the application.
4511 Affected files lib/silcclient/command.c and silc/client_ops.c.
4513 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Added channel key re-key support. The re-key is perfomed
4518 only by the router and is done once in an hour. Added `rekey'
4519 field to the SilcChannelEntry in the server. Affected files
4520 silcd/server.c and silcd/idlist.h.
4522 * Added silc_task_unregister_by_context into the file
4523 lib/silcutil/silctask.[ch].
4525 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Added SILC_UMODE_GONE mode to indicate when the client is not
4528 present in the SILC network. Added also support to the local
4529 command AWAY that will set this mode. Added support of showing
4530 "xxx is gone" in WHOIS command. The USERS command shows the
4531 gone status as well.
4533 * Fixed setting server and router operator privileges in the
4534 server's UMODE command. Affected file silcd/command.c.
4536 * Merged the SKE KE1 and KE2 payloads into one payload. The
4537 new KE payload is equivalent to the old KE2 payload.
4539 Cleaned up the SKE Start Payload parsing. It now uses the
4540 simple buffer unformatting to do the parsing. A lot faster
4543 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4544 to the SKE that is used to indicate whether both of the SKE
4545 parties should perform authentication. By default only the
4546 responder performs authentication. By setting this flag also
4547 the initiator must do authentication. By default it is unset
4548 since in normal SKE case, client to server connection, only
4549 the responder should do authentication. When doing SKE between
4550 two clients both should perform authentication. Updated the
4551 code and the protocol specs.
4553 * A little fix to IDENTIFY command in the server. Search the
4554 client first by hash not nickname. Affected file is
4557 * Fixed the silc_client_close_connection to support closing
4558 the client to client connections wihtout deleting too much
4559 data. Affected file lib/silcclient/client.c.
4561 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4562 are received if protocol used to be active but is not anymore
4563 the application would crash due to NULL pointer dereference.
4564 Affected files silcd/server.c and lib/silcclient/client.c.
4566 * Added `hash' field to the SilcClientConnection to include
4567 the hash function negotiated in the SKE protocol.
4569 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4570 to set the channel founder authentication data. A client can
4571 claim the founder rights later by providing the authentication
4572 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4573 This way the channel founder can regain the channel founder
4574 privileges even it is left the channel. This works only on
4575 local server and the client must be connected to the same
4576 server to be able to regain the founder rights. Updated the
4577 protocol specs accordingly.
4579 Added support to the CMODE command in the client to set the
4580 founder auth data. Read the README to see how to set it.
4582 Added support to the CUMODE command to claim the founder
4583 rights. Read the README to see how to do it.
4585 Added support for the founder authentication to the Channel
4586 Entry in the server. Affected file silcd/idlist.h.
4588 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4589 server's CMODE command. Affected file silcd/command.c.
4591 * Added the following new functions into lib/silccore/silcauth.[ch]:
4592 silc_auth_get_method and silc_auth_get_data.
4594 * The server now saves the remote hosts public key to the
4595 SilcIDListData pointer. Affected file silcd/protocol.c.
4597 * The normal server now does not remove the channel entry from
4598 the cache if the founder authentication data is set. It used
4599 to remove it if the founder was the last one on the channel on
4600 the server and left the channel. The auth data is saved and
4601 if the channel is re-joined later the old entry is used with
4602 the old auth data. Affected files silcd/command_reply.c and
4605 * Removed the `pkcs' field from the SilcIDListData structure
4606 in the server; it is not used. Affected file silcd/idlist.h.
4608 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Fixed packet processing on slow links. Partial packets were
4611 never re-processed because the incoming data buffer was cleared
4612 by the application. Application must not directly clear the
4613 sock->inbuf, the packet processing routines handle it. Fixed
4614 this in client library and in server.
4616 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Fixed the WHOIS and IDENTIFY send reply function to really
4619 check whether to send list or just one entry. Affected file
4622 * Cleaned up the LEAVE command's channel key distribution. The
4623 affected file silcd/command.c.
4625 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4626 can enforce the channel mode as well. In that case the ID
4627 includes the ID of the server. The code now enforces the
4628 mode change if the router have different mode than the server.
4630 * The notify client operation with CMODE_CHANGE notify can now
4631 return NULL client_entry pointer if the CMODE was not changed
4632 by client. Application must check for this.
4634 * Added <Server ID> argument to INFO command to support server
4635 info fetching by Server ID.
4637 * Added silc_server_announce_get_channel_users to get assembled
4638 packets of channel users of the specified channel. Affected
4639 file silcd/server.[ch].
4641 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4642 was freed underneath the ID Cache.
4644 * Re-announce clients when the server received CHANNEL_CHANGE
4645 notify from the router. Affected file silcd/packet_send.c.
4647 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4650 crashed since it did not handle the fact that there is no cipher
4651 called "3" and didn't check the error condition. Now fixed.
4653 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4654 flag. It can be used to send message requests.
4656 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Implemented the RESTART command in the client.
4660 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4661 notice type messages. Added notice printing to the user
4664 * The channel keys are not re-generated if the channel's mode
4665 is PRIVKEY, ie private key on the channel exists. Affected
4666 files silcd/server.c and silcd/command.c.
4668 * Fixed a little bug in channel message delivery when channel
4669 private keys are set in the server. Affected file is
4670 silcd/packet_send.c.
4672 * Changed the setting on channel->on_channel = TRUE from the
4673 silc_client_save_channel_key to the JOIN command reply. The
4674 key payload is not received if the private channel key is set.
4675 Affected file lib/silcclient/command_reply.c and the
4676 lib/silcclient/client_channel.c.
4678 * When the CMODE_CHANGE notify is sent and the channel private
4679 key mode is removed the channel key must be re-generated in
4680 other cells as well. Added this support for the router in the
4681 silcd/packet_receive.c.
4683 * Added new local command NOTICE to send notice message on
4684 channel. Affected file silc/local_command.[ch].
4686 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Added new local command ME to the client. It is used to send
4689 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4690 some action. Affected file silc/local_command.[ch].
4692 * Changed channel_message and private_message client operations
4693 to deliver the message flags to the application. Added also
4694 the `flags' arguments to the silc_client_send_channel_message
4695 and silc_client_send_private_message functions. Affected file
4698 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * Redefined the Private Message Payload to support private message
4701 keys and to support the new private message flags. Updated
4702 the protocol specs. Flags makes it possible to have for example
4703 CTCP style messages.
4705 * Added new type SilcPrivateMessagePayload and defined an API
4706 for it in the lib/silcclient/silcprivate.[ch].
4708 * Tested private message private keys successfully. Tested the
4709 private message key set, unset and list commands with the new
4712 * Redefined the Channel Message Payload to include the channel
4713 message flags (equal with private message flags) to support
4714 for example CTCP style messages.
4716 * Defined some of the message (for channel and private message)
4717 flags. Updated the protocol specs and added the flags to the
4718 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4720 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4722 * Added SilcKeyAgreementStatus type to the key agreement routines
4723 to indicate the current status and error if one occured.
4724 The status types are defined in the lib/silcclient/silcapi.h.
4726 * Added new local command KEY that is used to set and unset private
4727 keys for channels, set and unset private keys for private messages
4728 with remote clients and to send key agreement requests and
4729 negotiate the key agreement protocol with remote client. The
4730 key agreement is supported only to negotiate private message keys,
4731 it currently cannot be used to negotiate private keys for channels,
4732 as it is not convenient for that purpose.
4734 * Fixed a minor pending callback setting bug in the function
4735 silc_client_get_client_by_id_resolve, now the function works.
4736 Affected file lib/silcclient/idlist.c.
4738 * Added function silc_net_get_local_port to get local bound
4739 port by socket. Added to lib/silcutil/silcnet.[ch].
4741 * Added `sockets' and `sockets_count' fields to the SilcClient
4742 object. They hold the sockets of the listenning sockets in
4743 the client. Listenning sockets may be for example the key
4744 agreement server. Affected file lib/silcclient/client.[ch].
4745 Added functions the silc_client_add_socket and the
4746 silc_client_del_socket. They are exported to the application
4749 * Added ~./silc/clientkeys to support other client's public keys.
4751 * Renamed verify_server_key client operation to verify_public_key
4752 and added one argument to indicate the type of the connection
4753 (server, client etc.).
4755 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4757 * Added silc_server_connection_auth_request to handle the
4758 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4759 silcd/packet_receive.[ch].
4761 * Added silc_server_send_connection_auth_request into the
4762 silcd/packet_send.c to send the connection auth request packet.
4764 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4767 * Fixed the public key authentication in responder side in the
4768 server. The `auth_data' pointer includes the SilcPublicKey
4769 not the path to the public key. Affected file silcd/protocol.c.
4771 * Implemented the public key authentication in the initiator side
4772 in the server. Affected file silcd/protocol.c.
4774 * Removed the [RedirectClient] config section from the server
4775 configuration. Is not needed and I don't want to implement it.
4777 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Cleaned up the CMODE command in the server. It now works
4780 correctly and supports all the modes defined in the protocol.
4781 Affected file is silcd/command.c.
4783 * Added `hmac_name' field to the SilcChannelEntry in the server
4784 to hold the default HMAC of the channel. It can be set when
4785 creating the channel (with JOIN command). Affected files
4788 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4789 type to indicate the change of the current cipher and hmac
4790 on the channel. Client can safely ignore the <cipher> argument
4791 (if it chooses to do so) since the CHANNEL_KEY packet will
4792 force the channel key change anyway. The <hmac> argument is
4793 important since the client is responsible of setting the new
4794 HMAC and the hmac key into use.
4796 * Fixed the CMODE command in the client library as well.
4798 * Tested CMODE command in router environment successfully.
4800 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Show the version of the remote client (or server) when connecting
4803 to the server. It is logged to the log file. Affected file
4804 is silcd/protocol.c.
4806 * Fixed the KILLED notify handling in the client library. The
4807 client must be removed from all channels when receiving the
4810 Also, do not remove the client entry when giving the KILL
4811 command but when the KILLED notify is received.
4813 * Removed silc_idlist_find_client_by_nickname from the server.
4814 Not needed anymore. Affected files silcd/idlist.[ch].
4816 * Implemented the CHANNEL_CHANGE notify type handling to the
4817 server. Affected file silcd/server.c.
4821 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4824 notify between routers.
4826 * Implemented the INVITE command correctly to the server.
4828 * Implemented the INVITE notify type handling in the server.
4830 * Implemented the INVITE command to the client library and on the
4833 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * Added function silc_server_get_client_resolve to find the
4836 client entry by ID from all ID lists and then resolve it
4837 (using WHOIS) if it cannot be found. Affected file is
4840 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Implemented the BAN command to the client library.
4844 * The JOIN command in the server now checks the invite list
4847 * Changed the silc_command_reply_payload_encode_va and the
4848 silc_command_payload_encode_va to support that if argument is
4849 NULL it ignores and checks the next argument. Affected file
4850 lib/silccore/silccommand.c.
4852 * Added silc_server_send_notify_ban to send the BAN notify
4853 type between routers.
4855 * Chaned the silc_notify_payload_encode to support that if
4856 argument is NULL it ignores and checks the next argument.
4857 Affected file lib/silccore/silcnotify.c.
4859 * Tested ban lists in router environment successfully.
4861 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Implemented BAN command to the server, in silcd/command.[ch].
4865 * Removed the BAN and INVITE_LIST modes from the CMODE command
4868 * Added function silc_string_match to regex match two strings.
4869 Affected files lib/silcutil/silcutil.[ch].
4871 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Redefined parts of the SilcChannelEntry in the server to support
4874 the new ban and invite lists.
4876 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Redefined the INVITE command. The same command can be used to
4879 invite individuals to the channel but also to manage the invite
4880 list of the channel (to add to and remove from the invite list).
4881 Updated the protocol specs.
4883 * Added new command SILC_COMMAND_BAN that can be used to manage
4884 the ban list of the channel. Updated the protocol specs.
4886 * Removed the channel modes: the SILC_CMODE_BAN and the
4887 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4888 in the CMODE command. The equivalent features are now available
4889 using INVITE and BAN commands. Updated the protocol specs.
4891 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4892 in the network about change in the current ban list. The notify
4893 type is not used by the client.
4895 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4896 support the invite lists.
4898 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * Added new function silc_string_regexify that converts string
4901 including wildcard characters into regex string that can
4902 be used by the GNU regex library. Added into the file
4903 lib/silcutil/silcutil.[ch].
4905 Added silc_string_regex_combine to combine to regex strings
4906 into one so that they can be used as one regex string by
4907 the GNU regex library. Added into the file
4908 lib/silcutil/silcutil.[ch].
4910 Added silc_string_regex_match to match two strings. It returns
4911 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4913 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4915 * Imported GNU regex to the soruce tree into lib/contrib.
4916 Fixed some compiler warning from the regex.c.
4918 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4920 * Fixed MOTD command in the server to work in router environment.
4922 * Fixed the MOTD command in the client library to support
4923 the server argument in the command.
4925 * Added `nickname_len' argument to the silc_idlist_add_client
4926 in the server, as the `nickname' argument may be binary data
4929 * Added silc_idlist_get_channels to return all channels from
4932 * Implemented LIST command to the server. Affected file is
4935 * Implemented the LIST command to the client library and on the
4938 * Added [<user count>] argument to the LIST command reply.
4939 With private channels the user count is not shown.
4941 * Updated TODO and README.
4943 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * The client entry's data.registered must be TRUE even with
4946 global client entry on global client list. The data.registered
4947 is used to check whether the client is anymore in the network,
4948 for example with WHOWAS command so it must be valid.
4950 * Fixed the WHOWAS command in the server. It now actually works
4951 in router environment. Added function into silcd/command_reply.c
4952 silc_server_command_reply_whowas_save.
4954 * Added silc_idlist_purge function to the silcd/idlist.c
4955 to periodically purge the ID Cache.
4957 * Fixed INFO command in the server. It works now in router
4958 environment. Added <server name> argument to the INFO command
4959 reply. Updated the protocol specs.
4961 * Fixed minor bug in silc_idcache_purge to not purge if the
4962 expire value is zero.
4964 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4965 they were buggy because of the WHOWAS information.
4967 * Fixed local command MSG to handle the async resolving of
4968 the remote client properly. It used to fail the first MSG.
4969 Affected file silc/local_command.c.
4971 * Added `data_len' field to SilcIDCache context.
4973 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4975 * Update TODO. Todo in commands in the server.
4977 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4980 used by routers as broadcast packet to inform other routers
4981 about the changed user mode.
4983 Implemented the notify handling in the server. Affected file is
4984 silcd/packet_receive.c. Added the function
4985 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4987 * Added new generic Channel Payload and deprecated the New Channel
4988 Payload. The New Channel Payload is now the generic Channel
4991 * Added new argument `mode' to the silc_server_send_new_channel
4992 as it is required in the Channel Payload now.
4994 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4995 and created a new and real SilChannelPayload to represent the
4996 new generic Channel Payload. Implemented the encode/decode
4997 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4999 * Added silc_server_get_client_channel_list to return the list
5000 of channels the client has joined for WHOIS command reply.
5001 Affected file silcd/server.[ch].
5003 * Implemented the channel list sending in the WHOIS command reply
5004 in server and in the client.
5006 Implemented the channel list displaying on the user interface
5007 as well. Affected file silc/client_ops.c.
5009 * Added silc_channel_payload_parse_list to parse list of Channel
5010 Payloads. It returns SilcDList list of SilcChannelPayloads.
5011 Client for example can use this function to parse the list of
5012 channels it receives in the WHOIS command reply. The caller
5013 must free the list by calling silc_channel_payload_list_free.
5014 Affected files lib/silccore/silcchannel.[ch].
5016 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * Added one new argument <user mode> to the WHOIS command reply
5019 to return the mode of the user in SILC. Updated the protocol
5022 Implemented it to the server and client.
5024 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Fixed the mode printing on the user interface on joining.
5027 Affected file silc/client_ops.c.
5029 * Implemented the UMODE command and user modes in general to the
5030 client library and to the user interface.
5032 * Implemented the UMODE command to the server.
5034 * The server now sends UNKNOWN_COMMAND error status if client sends
5035 unknown command. Affected file silcd/command.c.
5037 * All server commands now handle the command identifier the right
5038 way when sending the command reply to the client. The client can
5039 use to identify the command replies with the identifier.
5041 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Added silc_server_get_client_route to resolve the route to
5044 the client indicated by the client ID. Affected file is
5047 * Added silc_server_relay_packet as general function to relay
5048 packet to arbitrary destination. This deprecates functions
5049 like _send_private_message_key, _relay_notify etc. Affected
5050 file is silcd/packet_send.[ch].
5052 Removed silc_server_send_key_agreement,
5053 silc_server_send_private_message_key and
5054 silc_server_packet_relay_notify functions from the file
5055 silcd/packet_send.[ch].
5059 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5060 server. Affected file silcd/packet_receive.[ch].
5062 * Implemented the KILL command to the client. Implemented the
5063 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5064 Affected files lib/silcclient/command[_reply].c and
5065 lib/silcclient/client_notify.c. Implemented the KILL notify
5066 printing in the user inteface.
5068 * Fixed a lot silc_parse_nick memory leaks from the client
5069 library in the file lib/silcclient/command.c.
5071 * Changed the silc_server_send_notify_on_channels's `sender'
5072 argument from SilcSocketConnection to SilcClientEntry to
5073 check the sender as entry and not as connection object and not
5074 to send to the client provided as argument. The affected file
5075 is silcd/packet_send.[ch].
5077 * The notify packets that are destined directly to the client used
5078 to not to be processed by the server. Now changed that and the
5079 server processes all notify packets. After relaying the packet
5080 to the client the notify packet is processed in the server.
5082 * The silc_server_free_client_data now checks whether there is
5083 pending outgoing traffic for the client and purges the data to
5084 the network before removing the client entry.
5086 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5089 an client is killed from the SILC Network. Updated the protocol
5092 Added new function silc_server_send_notify_killed to the
5093 silcd/packet_send.[ch].
5095 * Added function silc_server_packet_relay_notify to relay notify
5096 packets that are destined directly to a client. In this case
5097 the server does not process the notify packets but merely relays
5098 it to the client. Affected file silcd/packet_send.[ch].
5100 Added also silc_server_packet_process_relay_notify to check
5101 whereto relay the notify. Affected file is
5102 silcd/packet_receive.[ch].
5104 * Implemented the KILL command to the server.
5108 * Added the backup schema desgined last fall to the protocol
5109 specs for everyone to see. The specification is in the
5110 *-spec-xx.txt draft and the packet type definitions for the
5111 backup routers is in *-pp-xx.txt draft. Thusly, added also
5112 new packet type SILC_PACKET_CELL_ROUTERS.
5114 * A big security problem in the implementation discovered. The
5115 signoff of an client did not cause new channel key generation
5116 which it of course should've done. The channel keys must be
5117 always re-generated when client leaves (or signoffs) the channel.
5118 The silc_server_remove_from_channels funtion now handles
5119 the channel key re-generation.
5121 * Added `sender' argument to the silc_server_send_notify_on_channels
5122 to not to send the client provided as argument. Affected file
5123 silcd/packet_send.[ch].
5125 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Implemented OPER and SILCOPER commands into the server and
5130 * Added silc_auth_verify and silc_auth_verify_data to verify
5131 the authentication directly from the authentication payload.
5132 It supports verifying both passphrase and public key based
5133 authentication. Affected file lib/silccore/silcauth.[ch].
5135 * Added `hash' field to the SilcIDListData structure. It is the
5136 hash negotiated in the SKE protocol. Affected file is
5139 * Slight redesigning of the SilcAuthPayload handling routines.
5140 Do not send SilcPKCS but SilcPublicKey as argument.
5142 * Implemented the public key authentication support to the
5143 serverconfig. The public key is loaded from the provided path
5144 and saved as authentication data to void * pointer. Thus,
5145 changed the unsigned char *auth_data to void *auth_data;
5147 * Fixed SHUTDOWN command to send the reply before the server
5148 is shutdown. :) Affected file silcd/command.c.
5150 * Fixed fatal bug in CONNECT command. The hostname was invalid
5151 memory and server crashed. Affected file silcd/command.c.
5153 * Fixed fatal bug in CLOSE command. The server_entry became
5154 invalid but was referenced later in the command. Affected file
5157 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Fixed fatal bug in failure packet handling. Server ignored
5160 the failure and thus crashed when it came.
5164 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5167 that the command may be executed only once in (about) 2 seconds.
5168 The old SILC_CF_LAG flag is same but allows command bursts up
5169 to five before limiting.
5171 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5172 server code. Various commands now includes the CF_LAG_STRICT
5173 flag to disallow any kind of miss-use of the command.
5175 * Fixed the silc_buffer_unformat to not to allocate any data
5176 if the length of the data is zero. It used to allocate the
5177 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5179 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Changed the format of AdminConnection configuration section
5182 in the server. Added username of the admin to the format.
5183 Affected files silcd/serverconfig.[ch].
5185 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5186 to return admin configuration data by host, username and/or
5189 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Implemented WHOWAS command to the server. Added the functions:
5193 silc_server_command_whowas_parse,
5194 silc_server_command_whowas_send_reply,
5195 silc_server_command_whowas_from_client and
5196 silc_server_command_whowas_from_server
5198 * Added <Client ID> argument to the WHOWAS command reply. Updated
5199 the protocol specs accordingly.
5201 * Implemented WHOWAS command and command_reply to the client
5204 Implemented the WHOWAS printing on the user interface.
5206 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Added new argument to the WHOWAS command reply, the real name.
5209 It is an optional argument. Updated the protocol specs.
5211 * Added SilcIDCacheDestructor callback that is registered when
5212 the SilcIDCache is allocated. The callback is called when
5213 an cache entry in the ID Cache expires, or is purged from the
5214 cache. Added into lib/silccore/idcache.[ch].
5216 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5217 to destruct the client entries when the cache entry expires.
5218 Other ID Cache's in server and in the client library ignores
5221 * If the ID Cache entry's `expire' field is zero then the entry
5222 never expires. Added boolean `expire' argument to the
5223 silc_idcache_add function in the lib/silccore/idcache.[ch].
5224 If it is TRUE the default expiry value is used.
5226 * Added silc_server_free_client_data_timeout that is registered
5227 when client disconnects. By default for 5 minutes we preserve
5228 the client entry for history - for WHOWAS command.
5230 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Added support to the server to enforce that commands are not
5233 executed more than once in 2 seconds. If server receives
5234 commands from client more frequently, timeout is registered
5235 to process the commands. Affected file silcd/command.c.
5236 Added new function silc_server_command_process_timeout.
5238 * Changed NICK_NOTIFY handling in client library to check that
5239 if the client's nickname was changed, so there is no need to
5240 resolve anything from the server.
5242 * Removed error printing from the WHOIS and IDENTIFY commands.
5243 If error occurs then it is ignored silently in the client library.
5244 The application, however, may map the received error to
5245 human readable error string. The application currently maps
5246 the NO_SUCH_NICKNAME error to string.
5248 * Made the command status message public to the application. Moved
5249 them from lib/silcclient/command_reply.c to
5250 lib/silcclient/command_reply.h. The application can map the
5251 received command status to the string with the
5252 silc_client_command_status_message function.
5254 * Added check to the server to check that client's ID is same
5255 as the Source ID in the packet the client sent. They must
5258 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Added dist-bzip hook to the Makefile.am to make bzip2
5261 compressed distributions.
5263 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Server now enforces the maximum length for the nickname and
5266 the channel as protocol specification dictates. 128 bytes for
5267 nickname and 256 bytes for channel name.
5269 * Moved the WHOIS printing to the application. The client libary
5270 does not print out the WHOIS information anymore, the application
5271 must do it. Renamed silc_client_command_reply_whois_print to
5272 the silc_client_command_reply_whois_save.
5274 The client's idle time is also sent to the application now, and
5275 the idle is shown on screen.
5277 * Added silc_client_command_reply_identify_save to save the
5278 received IDENTIFY entries.
5280 * Do not check for channel private keys in message sending and
5281 reception if the channel does not have the PRIVKEY mode set.
5282 Affected file lib/silclient/client_channel.c.
5284 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5287 just surfaced after chaning the JOIN procedure.
5289 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Added silc_client_get_clients_by_list to get client entries
5292 from Client ID list, that is returned for example by JOIN
5293 and USERS command replies. The application should use this
5294 function for example when JOIN command reply is received to
5295 resolve the clients already on the channel (library does not
5296 do that anymore as USERS command reply is not used in the JOIN
5297 procedure anymore). Affected files lib/silcclient/silcapi.h and
5298 lib/silcclient/idlist.c.
5300 * JOIN command reply and USERS command reply returns now SilcBuffer
5301 pointers instead of unsigned char pointers when returning
5302 the client list and mode list.
5304 * Added <Client ID> argument to the JOIN command reply, mainly
5305 for the server to identify for which client the command was
5306 originally sent. Updated protocol specs accordingly.
5308 * Added SilcDlist private_key pointer to the SilcChannelEntry
5309 in the client to support the channel private keys. Affected
5310 file is lib/silcclient/idlist.h.
5312 * Added SilcChannelPrivateKey argument to the function
5313 silc_client_send_channel_message so that application can choose
5314 to use specific private ke if it wants to. If it is not provided,
5315 the normal channel key is used, unless private keys are set.
5316 In this case the first (key that was added first) is used
5317 as the encryption key.
5319 * Implemented the support for channel private key handling.
5320 Implemented the following functions:
5322 silc_client_add_channel_private_key,
5323 silc_client_del_channel_private_keys,
5324 silc_client_del_channel_private_key,
5325 silc_client_list_channel_private_keys and
5326 silc_client_free_channel_private_keys
5328 Affected file lib/silcclient/client_channel.c.
5330 * Added the support for the private keys in the channel message
5331 sending and encryption and in the message reception and
5332 decryption. Affected funtions are
5333 silc_client_send_channel_message and silc_client_channel_message.
5335 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Added SKE's key verify callback to the client library's
5338 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5340 * Removed the statement that server (or router) must send USERS
5341 command reply when joining to the channel so that the client
5342 knows who are on the channel. Instead, the client list and
5343 client's mode list is now sent in the JOIN command reply to the
5344 client who joined channel. This is better solution.
5346 * Added function silc_server_get_users_on_channel and function
5347 silc_server_save_users_on_channel to the silcd/server.[ch].
5349 * Removed function silc_server_command_send_users from the
5352 * Do not show topic on the client library anymore. The topic is
5353 sent in the command reply notify to the application and the
5354 application must show the topic now.
5356 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Added client searching by nickname hash into the IDENTIFY and
5359 WHOIS commands in the server as they were clearly missing from
5360 them. Affected file is silcd/command.c.
5362 * Fixed a bug in private message receiving in the client library.
5363 The remote ID was freed and it wasn't supposed, now it is
5366 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Minor fix to the channel payload; allocate the data area, as it
5369 needs to be of specific length.
5371 * If the key agreement port is zero then the operating
5372 system will define the bound port. Affected files are
5373 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5375 * Added new function silc_channel_payload_decrypt into the file
5376 lib/silccore/silcchannel.[ch].
5378 * Moved the channel message etc, check from silc_packet_decrypt
5379 to applications. The library calls now a generic
5380 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5381 when the packet is either normal or special. This was done to
5382 allow more wide range of checking that was not allowed when
5383 the code was in library. Now applications can do virtually any
5384 checks to the packet and return to the library the decision how
5385 the packet should be processed. Affected files are
5386 lib/silccore/silcpacket.[ch].
5388 Added silc_server_packet_decrypt_check to the server and
5389 silc_client_packet_decrypt_check to the client library.
5391 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5392 to send with specified source and destination information.
5394 * Channel message delivery between routers was broken after the
5395 channel key distribution was fixed earlier. The channel key
5396 was used be to distributed to other routers as well which is not
5397 allowed by the protocol. Now this is fixed and channel keys
5398 really are cell specific and the channel message delivery between
5399 routers comply with the protocol specification.
5401 * Fixed various commands in server to check also the global list
5402 for the channel entry and not just the local list. The affected
5403 file silcd/command.c.
5405 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Added assert()s to buffer formatting and unformatting routines
5408 to assert (if --enable-debug) when error occurs. Affected
5409 file: lib/silcutil/silcbuffmt.c.
5411 * Changed to auto-reconnect to check whether the remote host is
5412 router and register the re-connect timeout if it is. It used
5413 to check that whether we are normal server, but router must do
5414 auto-reconnect with another router as well. Affected file
5417 * Removed the [<key len>] option from CMODE command as the cipher
5418 name decides the key length, nowadays. See the defined ciphers
5419 from the protocol specification.
5421 * Added [<hmac>] option to the CMODE command to define the HMAC
5422 for the channel. Added SILC_CMODE_HMAC channel mode.
5424 * Added [<hmac>] option for the JOIN command so that user can
5425 select which HMAC is used to compute the MACs of the channel
5428 * Added Hmac field to the Channel Message Payload. The integrity
5429 of plaintext channel messages are now protected by computing
5430 MAC of the message and attaching the MAC to the payload. The
5431 MAC is encrypted. Now, it is clear that this causes some
5432 overhead to the size of the packet but rationale for this is that
5433 now the receiver can verify whether the channel message decrypted
5434 correctly and also when private keys are set for the channel the
5435 receiver can decrypt the packet with several keys and check from
5436 the MAC which key decrypted the message correctly.
5438 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5439 lib/silccrypt/silccipher.[ch].
5441 * Added silc_hash_len to return the digest length into the
5442 lib/silcrypt/silchash.[ch].
5444 * Rewrote parts of Silc Channel Payload interface in the
5445 lib/silccore/silcchannel.[ch]. The encode function now also
5446 encrypts the packet and parse function decrypts it.
5448 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Fixed a minor formatting bug in the SKE's key material processing.
5451 It actually might have processed the keys wrong way resulting
5454 * Redefined the mandatory HMAC algorithms and added new algorithms.
5455 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5456 and hmac-md5 truncated to 96 bits. The mandatory is now
5457 hmac-sha1-96. Rest are optional (including the one that used
5458 to be mandatory). Rationale for this is that the truncated HMAC
5459 length is sufficient from security point of view and can actually
5460 make the attack against the HMAC harder. Also, the truncated
5461 HMAC causes less overhead to the packets. See the RFC2104 for
5464 * Added new [hmac] configuration section. The SKE used to use
5465 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5466 is of course wrong. The official names that must be proposed in
5467 the SKE are the ones defined in the protocol specification
5468 (hmac-sha1-96 for example). The user can configure any hmac
5469 using any hash function configured in the [hash] section. At
5470 least, the mandatory must be configured.
5472 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5474 * Added HMAC list to the SKE proposal list. It has now both
5475 hash algorithm list and HMAC list. This makes the protocol
5476 incompatible with previous versions. The SKE now seems to work
5477 the way it is supposed to work, for the first time actually.
5479 * Defined plain Hash algorithms to the protocol specification.
5482 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * Implemented support for key agreement packets into the server.
5485 Added functions silc_server_key_agreement and
5486 silc_server_send_key_agreement. Other than these functions,
5487 server has nothing to do with this packet.
5489 * Added support for private message key packets into the server.
5490 Added functions silc_server_private_message_key and
5491 silc_server_send_private_message_key.
5495 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5496 called in the protocol's final callback instead in the END
5497 protocol state. This makes a little more sense and in the same
5498 time in client we can use the same protocol routines for normal
5499 key exchange and to key agreement packet handling as well.
5501 * Added to both client's and server's KE protocol context the
5502 SilcSKEKeyMaterial pointer to save the key material. We will
5503 bring the key material to the protocol's final callback by doing
5504 this. The final callback must free the key material.
5506 * Added SKE's packet_send callback into client's KE protocol
5507 context so that the caller can choose what packet sending function
5508 is used. This way we can use different packet sending when
5509 doing normal SKE when doing key agreement packet handling (in
5510 the key agreement packet handling we do not want to encrypt
5513 * Implemented the responder side of the key agreement routines
5514 in the client. The client can now bind to specified port and
5515 accept incoming key negotiation. The key material is passed
5516 to the application after the protocol is over.
5518 * Implemented the processing of incoming Key Agreement packet
5519 in the client. Added function silc_client_key_agreement to
5522 * Implemented the intiator side of the key agreement routines
5523 in the client. The client can now initiate key agreement with
5524 another remote client. The key material is passed to the
5525 application after the protocol is over.
5527 * Created client_keyagr.c to include all the key agreement
5530 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5531 SILC_TASK_CALLBACK except that it is not static.
5533 * Created client_notify.c and moved the Notify packet handling
5534 from the client.[ch] into that file.
5536 * Created client_prvmsg.c and moved all private message and
5537 private message key routines from the client.[ch] into that file.
5539 * Create client_channel.c and moved all channel message and
5540 channel private key routines from the client.[ch] into that file.
5542 * Changed silc_client_get_client_by_id_resolve to resolve with
5543 WHOIS command instead of IDENTIFY command, in the file
5544 lib/silclient/idlist.c.
5546 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Implemented the SKE's responder side to the Client library.
5550 * When FAILURE is received to the protocol do not trust it
5551 blindly. Register a timeout to wait whether the remote closes
5552 the connection as it should do it, only after that process the
5553 actual failure. This was changed to both client and server.
5555 * Added client_internal.h to include some of the structures
5556 there instead of client.h in lib/silcclient/.
5558 * Added function silc_task_unregister_by_callback to unregister
5559 timeouts by the callback function.
5561 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Some "Incomplete WHOIS info" errors has been appearing on the
5564 log files. Took away the entry->userinfo check from WHOIS
5565 reply sending. The entry->userinfo is now " " if client did not
5566 provide one. I thought this was fixed earlier but something
5567 is wrong still. Let's see if the error still appears.
5569 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * Fixed a minor bug in the login when the channel key is
5572 re-generated in the server. It used to generate the key in
5573 wrong order and thus caused problems in the channel traffic.
5575 * Fixed a minor bug in channel key distsribution after
5576 KICK command. The key was not sent to the router even though
5579 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * Added silc_ske_process_key_material_data as generic routine
5582 to process any key material as the SILC protocol dictates. The
5583 function is used by the actual SKE library but can be used by
5584 applications as well. This relates to the private message keys
5585 and the channel private keys since they must be processed the
5586 same way the normal SILC session keys. The protocol dictates
5587 this. Affected files: lib/silcske/silcske.[ch].
5589 Added also silc_ske_free_key_material to free the
5590 SilcSKEKeyMaterial structure.
5592 * Defined silc_cipher_set_key function to set the key for
5593 cipher without using the object's method function. The affected
5594 files: lib/silccrypt/silccipher.[ch].
5596 * Implemented silc silc_client_add_private_message_key,
5597 silc_client_add_private_message_key_ske,
5598 silc_client_del_private_message_key,
5599 silc_client_list_private_message_keys and
5600 silc_client_free_private_message_keys functions in the
5603 Added functions silc_client_send_private_message_key to send
5604 the Private Message Key payload and silc_client_private_message_key
5605 to handle incoming Private Message Key payload.
5607 * Added Cipher field to the Private Message Key payload to set
5608 the cipher to be used. If ignored, the default cipher defined
5609 in the SILC protocol (aes-256-cbc) is used.
5611 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5613 * Removed lib/silcclient/ops.h file.
5615 Redefined parts of the SILC Client Library API. Created new
5616 file silcapi.h that deprecates the ops.h file and defines the
5617 published Client Library API. Defined also private message key
5618 API and channel private key API into the file.
5620 This is the file that the application must include from the
5621 SILC Client Library. Other files need not be included by
5622 the application anymore.
5624 * Added new key_agreement client operation callback and also
5625 defined the Key Agreement library API for the application.
5627 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5630 is used by clients to request key negotiation between another
5631 client in the SILC network. If the negotiation is started it
5632 is performed using the SKE protocol. The result of the
5633 negotiation, the secret key material, can be used for example
5634 as private message key.
5636 Implemented the Key Agreement payload into the files
5637 lib/silccore/silauth.[ch].
5639 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Redefined ciphers for the SILC protocol. Added some new ciphers
5642 and defined the key lengths for the algorithms. Changed the
5643 code accordingly. The default key length is now 256 bits.
5645 * Fixed SKE key distribution function silc_ske_process_key_material
5646 when the key length is more than 128 bits. The default key
5647 length in SILC is now 256 bits.
5649 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5650 to indicate unsupported algorithm.
5652 * Renamed rijndael.c to aes.c and all functions as well.
5654 * Fixed a long standing channel key setting bug in client library.
5655 Weird that it has never surfaced before.
5657 * Fixed bug in channel deletion. If the entire channel is removed
5658 then it must also delete the references of the channel entry
5659 from the client's channel list as the client's channel entry and
5660 the channel's client entry share same memory.
5662 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Implemented CONNECT and SHUTDOWN commands in the client.
5666 * Implemented CLOSE command to the client.
5668 * Added the function silc_idlist_find_server_by_name into the
5669 files silcd/idlist.[ch].
5671 Added the function silc_idlist_find_server_by_conn into the
5672 files silcd/idlist.[ch].
5674 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * DIE command was renamed to SHUTDOWN. Updated the both code
5679 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5680 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5682 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5685 * Added function silc_server_create_connection function to create
5686 connection to remote router. My server implementation actually
5687 does not allow router to connect to normal server (it expects
5688 that normal server always initiates the connection to the router)
5689 so the CONNECT command is only good for connecting to another
5692 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5694 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5695 or some other client was kicked from the channel.
5697 Implemented the handling of the notify type to both client
5700 Implemented silc_server_send_notify_kicked to send the KICKED
5701 notify. It is used to send it to the server's primary router.
5703 * Implemented the KICK command into server and client.
5705 * Added `query' argument to the silc_idlist_get_client function
5706 to indicate whether to query the client from server or not if
5709 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5710 to indicate that the client is not channel founder.
5714 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Removed the rng context from SilcPacketContext structure and
5717 changed that the packet routine uses the Global RNG API.
5719 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * Added support for quit message that client can "leave" on the
5722 channel when it quits the SILC. It is ditributed inside the
5723 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5725 Added silc_server_free_client_data that will take the
5726 signoff message as argument.
5728 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5730 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Updated parts of the protocol specification to keep it up
5735 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5738 payloads in one packet.
5740 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5741 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5742 use now the new List flag.
5744 * Also deprecated the following packet types: REPLACE_ID,
5745 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5747 * Added list support for Notify packet in server.
5749 * Added silc_server_send_notify_channel_change to send the
5750 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5751 the silc_server_send_replace_id.
5753 * Added silc_server_send_notify_nick_change to send the
5754 NICK_CHANGE notify type. Deprecates the function
5755 silc_server_send_replace_id.
5757 * Added silc_server_send_notify_join to send the JOIN notify type.
5758 Deprecates the function silc_server_send_new_channel_user.
5760 * Added silc_server_send_notify_leave to send LEAVE notify type.
5761 Deprecates the function silc_server_send_remove_channel_user.
5763 * Added silc_server_send_notify_cmode and
5764 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5765 types. Deprecates the silc_server_send_set_mode function.
5767 * Added SERVER_SIGNOFF notify type to indicate that server has
5768 quit. This means that all clients on the channel from that
5769 server will drop. This can be also used when netsplit happens.
5771 Deprecated REMOVE_ID packet type since it is not needed anymore
5774 Added silc_server_send_notify_server_signoff to send the
5775 SERVER_SIGNOFF notify type. Deprecates the function
5776 silc_server_send_remove_id.
5778 Added also silc_server_send_notify_signoff to send the
5779 SIGNOFF notify type.
5781 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5782 SILC protocol from this day on. Changed the protocol
5783 specification as well.
5785 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5786 notify type. It is used between routers to notify about
5787 topic changes on a channel.
5789 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5792 * Partly updated the protocol specification to comply with the
5793 changes now made. It is still though a bit outdated.
5795 * The JOIN notify type now takes one extra argument <Channel ID>.
5796 The packet used to be destined to the channel but now the
5797 JOIN type may be sent as list thus it is impossible to
5798 destine it to any specific channel. By adding this argument
5799 it is again possible.
5801 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Added CREDITS file. The CHANGES and CREDITS file will appear
5804 in the distribution as well.
5806 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5809 types in the server's silcd/packet_receive.c.
5811 * Implemented CMODE and CUMODE to work in router environment.
5813 * Fixed minor encoding and decoding buglet from the
5814 lib/silccore/silcmode.c.
5816 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5819 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5821 * Changed all SilcConfigServer* and silc_config_server* to
5822 SilcServerConfig* and silc_server_config*, respectively.
5825 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Associated the ID (client or server ID) to the Authentication
5828 Payload to avoid any possibility of forging. Updated the
5829 protocol specification and the code accordingly.
5831 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5833 * The RSA key length is now save to the RsaKey context in the
5834 key generation process in lib/silccrypt/rsa.c. The key length
5835 is now used to figure out the maximum size of the block allowed
5836 to be encrypted/signed.
5838 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5839 is equivalent to the silc_mp_mp2bin but does not allocate any
5842 * Changed silc_mp_mp2bin API to take length argument. If it is
5843 non-zero then the buffer is allocated that large. If zero, then
5844 the size is approximated using silc_mp_sizeinbase, which however
5847 * Created Global RNG API which is global RNG that application can
5848 initialize. After initializing, any routine anywhere in the
5849 code (including library) can use RNG without allocating a new
5850 RNG object. This was done to allow this sort of use of the
5851 RNG in code that has no chance to allocate RNG object. All
5852 applications currently allocate this and many routines in the
5853 library use this. Affected file lib/silccrypt/silcrng.[ch].
5855 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5856 it to use the Global RNG API.
5858 * Defined Authentication Payload into protocol specification that
5859 is used during SILC session to authenticate entities. It is
5860 used for example by client to authenticate itself to the server
5861 to obtain server operator privileges.
5863 Implemented this payload into the lib/silccore/silcauth.[ch].
5864 Implemented also routines for public key based authentication
5865 as the new protocol specification dictates.
5867 Moved definitions of different authentication methods from
5868 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5870 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5871 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5872 silc_pkcs_verify_with_hash functions into the file
5873 lib/silccrypt/silcpkcs.[ch].
5875 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * The client entry's userinfo pointer must be always valid.
5878 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5879 will fail since it requires the userinfo. Now, the userinfo
5880 is allocated as "" if actual userinfo does not exist. Actually,
5881 it must exist and it is totally Ok to drop client connections
5882 that does not announce the userinfo. However, we will make
5883 this workaround for now.
5885 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5886 to return the remote port by socket.
5888 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5891 SILC_SERVER_PENDING_EXEC and added an new macro
5892 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5893 data or when error occurs while processing the pending command.
5895 Added new argument `destructor' into silc_server_command_pending
5896 and to the SilcServerCommandPending object. This destructor is
5897 now called after calling the pending callback or if error occurs
5898 immediately. If error occurs the actual pending callback won't
5899 be called at all - only the destructor. The destructor may be
5900 NULL if destructor is not needed.
5902 All this applies for client library code as well. Similar
5903 changes were made there as well for the pending commands.
5905 In the client, the application must now allocate the
5906 SilcClientCommandContext with the silc_client_command_alloc
5909 * Added reference counter to the SilcServerCommandContext. Added
5910 function silc_server_command_alloc and silc_server_command_dup
5913 Same type of functions added to the client library for the same
5916 * Removed the cmd_ident from IDListData away since it is now
5917 global for all connections. It is the command identifier used
5918 in command sending and with pending commands. The affected file
5921 * Added reference counter to the SilcSocketConnection objecet to
5922 indicate the usage count of the object. The object won't be
5923 freed untill the reference counter hits zero. Currently only
5924 server uses this, and client ignores it. The client must be
5925 set to use this too later. The affected files are
5926 lib/silccore/silcsockconn.[ch]. Added also the function
5927 silc_socket_dup to increase the reference counter.
5929 This was mainly added because it is possible that the socket
5930 is removed underneath of pending command or other async
5931 operation. Now it won't be free'd and proper DISCONNECTING
5932 flags, etc. can be set to avoid sending data to connection that
5933 is not valid anymore.
5935 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5936 the connection. After that it sets SILC_SET_DISCONNECTED.
5937 It is, however, possible that the socket data is not still freed.
5938 The silc_server_packet_process now checks that data is not
5939 read or written to connection that is DISCONNECTED. The socket
5940 get's freed when the reference counter hits zero.
5942 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Changed the client operation API: channel_message operation's
5945 `sender' is now the client entry of the sender, not the nickname
5946 and the `channel' is the channel entry, not the channel name.
5948 In the private_message operation the `sender' is now also the
5949 client entry of the sender not the nickname.
5951 Affected file is lib/silcclient/ops.h and all applications
5952 using the client operations.
5954 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Moved the calling of ops->connect() from connect_to_server_final
5957 into receive_new_id functin since that is the point when the
5958 client is actually allowed to send traffic to network. The
5959 affected file is lib/silcclient/client.c.
5961 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5964 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5965 (if needs broadcasting) instead of broadcasting the packets one
5966 by one which would make a burst in the network traffic.
5968 * Added `broadcast' argument to the functions in silcd/server.[ch]
5969 silc_server_create_new_channel[_with_id] to indicate whether
5970 to send New Channel packet to primary router.
5972 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5974 * Added new function into the silcd/server.[ch] files:
5975 silc_server_create_new_channel_with_id to create new channel with
5976 already existing Channel ID.
5978 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5979 lib/silccore/silcpacket.h. This packet is used t send list of
5980 Set Mode payloads inside one packet. Server uses this to set
5981 the modes for the channels and clients on those channels, that it
5982 announced to the router when it connected to it. The protocol
5983 specification has been updated accordingly.
5985 * The silc_server_new_channel did not handle the packet coming
5986 from normal server as it normally does not send that. However,
5987 when it announces its channels it does send it. Implemented
5988 the support for that.
5990 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5991 into the file lib/silccore/id.h.
5993 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Fixed memory leaks in the functions silc_idlist_del_client,
5996 silc_idlist_del_channel and silc_idlist_del_server in the file
5997 silcd/idlist.c. All of those leaked like a sieve.
5999 * Fixed some small memory leaks in the client's function
6000 silc_client_notify_by_server.
6002 * Added functions into silcd/server.c: silc_server_announce_clients,
6003 silc_server_announce_channels and silc_server_announce_server.
6004 These functions are used by normal and router server to announce
6005 to its primary router about clients, channels and servers (when
6006 router) that we own. This is done after we've connected to the
6009 These functions effectively implements the following packet types:
6010 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6011 and SILC_PACKET_NEW_ID_LIST.
6013 * Added new functions into the silcd/packet_receive.[ch]:
6014 silc_server_new_id_list, silc_server_new_channel_list and
6015 silc_server_new_channel_user_list to handle the incoming
6016 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6018 * Added support of changing Channel ID in the function
6019 silc_server_replace_id. If the server that announces a channel
6020 to the router already exists in the router (with same name but
6021 with different Channel ID), router is responsible to send
6022 Replace ID packet to the server and force the server to change
6023 the Channel ID to the one router has.
6025 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6026 client that the Channel ID has been changed by the router. The
6027 normal server sends this to the client. Client must start using
6028 the new Channel ID as the channel's ID.
6030 Implemented handling of this new type into lib/silcclient/client.c
6031 into the function silc_client_notify_by_server.
6033 * Added new function silc_idlist_replace_channel_id into the files
6034 silcd/idlist.[ch] to replace the Channel ID.
6036 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6038 * Call silc_server_command_identify_check always when processing
6039 the IDENTIFY command in silcd/command.c
6041 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6043 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6044 send keepalive packets. The packet can be sent by clients,
6045 servers and routers.
6047 Added function silc_socket_set_heartbeat into the file
6048 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6049 If not set, the heartbeat is not performed. The actual
6050 heartbeat is implemented in the low level socket connection
6051 library. However, application is responsible of actually
6054 Added silc_server_send_heartbeat to send the actual heartbeat
6055 packet into silcd/packet_send.[ch]. Server now performs
6056 keepalive with all connections.
6058 * Added silc_task_get_first function into lib/silcutil/silctask.c
6059 to return the timeout task with shortest timeout. There was a bug
6060 in task unregistration that caused problems. TODO has been
6061 updated to include that task system must be rewritten.
6063 * The client library will now resolve the client information when
6064 receiving JOIN notify from server for client that we know but
6065 have incomplete information.
6067 * Rewrote parts of silc_server_remove_from_channels and
6068 silc_server_remove_from_one_channel as they did not remove the
6069 channel in some circumstances even though they should've.
6071 * Encryption problem encountered in server:
6073 The LEAVE command used to send the Channel Key packet to the
6074 router immediately after generating it. However, the code
6075 had earlier sent Remove Channel user packet but not immediately,
6076 ie. it was put to queue. The order of packets in the router
6077 was that Channel Key packet was first and Remove Channel User
6078 packet was second, even though they were encrypted in the
6079 reverse order. For this reason, MAC check failed. Now, this
6080 is fixed by not sending the Channel Key packet immediately but
6081 putting it to queue. However, this is more fundamental problem:
6082 packets that are in queue should actually not be encrypted
6083 because packets that are sent immediately gets encrypted
6084 actually with wrong IV (and thus MAC check fails). So, packets
6085 that are in queue should be encrypted when they are sent to
6086 the wire and not when they put to the queue.
6088 However, the problem is that the current system has not been
6089 designed to work that way. Instead, the packet is encrypted
6090 as soon as possible and left to the queue. The queue is then
6091 just purged into wire. There won't be any fixes for this
6092 any time soon. So, the current semantic for packet sending
6095 o If you send packet to remote host and do not force the send
6096 (the packet will be in queue) then all subsequent packets to the
6097 same remote host must also be put to the queue. Only after the
6098 queue has been purged is it safe again to force the packet
6101 o If you send all packets immediately then it safe to send
6102 any of subsequent packets through the queue, however, after
6103 the first packet is put to queue then any subsequent packets
6104 must also be put to the queue.
6106 Follow these rules and everything works fine.
6108 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * Added new function silc_server_remove_clients_by_server to
6111 remove all client entries from ID list when the server connection
6112 is lost. In this case it is also important to invalidate all
6113 client entires as they hold the invalid server entry. This
6114 fixes fatal bug when server has lost connection and will reconnect
6117 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Made some sanity checks to silc_server_daemonise like to check
6120 whether the requested user and group actually exists.
6122 * Added sanity check to SKE's silc_ske_responder_finish to check
6123 that the public and private key actually is valid.
6125 * Invalidate the client's nickname when receiving Replace ID
6126 packet and the Client ID is being replaced. This means that the
6127 server will query the nickname if someone needs it (client)
6130 * Sort the ID Cache in client library when the ID Cache data
6131 has changed (needs sorting).
6133 * Do not allow for SILC client to create several connections to
6134 several servers. The client does not support windows right now
6135 and generating multiple connections causes weird behaviour.
6137 Irssi-silc client does support windows and can handle several
6138 connections without problems, see: www.irssi.org and SILC plugin.
6140 * Fixed some places where client was added to the IDList. The
6141 rule of thumb is following (in order to get everything right):
6142 If the client is directly connected local client then the
6143 `connection' argument must be set and `router' argument must be
6144 NULL to silc_idlist_add_client function. If the client is not
6145 directly connected client then the `router' argument must
6146 bet set and the `connection' argument must be NULL to the
6147 silc_idlist_add_client function.
6149 * The funtion silc_server_packet_send_local_channel actually did
6150 not check whether the client was locally connected or not. It
6151 does that now. Fixed a bug related to LEAVE command.
6153 * Fixed Remove Channel User payload parsing bug in server's
6154 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6156 * The server's silc_server_save_channel_key now checks also the
6157 global ID list for the channel as it might not be in the local
6158 list. Fixed a bug related to LEAVE command.
6160 * Is this the end of the [<unknown>] buglet that has been lurking
6161 around for a long time? A little for loop fix in server's
6162 silc_server_command_whois_parse that is used by both IDENTIFY
6163 and WHOIS command. At least, this was a clear bug and a cause
6164 of one type of [<unknown>] buglet.
6166 * WHOIS and IDENTIFY commands call the function
6167 silc_server_command_[whois/identify]_check function even if
6168 we are not router server.
6170 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Added --with-gmp configuration option. If set the GMP
6173 is always compiled in the SILC source tree. If not set then
6174 it is checked whether the system has the GMP3 installed. If
6175 it has then the GMP won't be compiled (the system's headers
6176 and library is used), if it doesn't have it then the GMP is
6177 compiled in the SILC source tree.
6179 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6181 * Changed RSA private exponent generation to what PKCS #1
6182 suggests. We try to find the smallest possible d by doing
6183 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6184 not security fix but optimization.
6186 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6188 * Added new config entry [Identity] to fork the server and run
6189 it as specific user and group. A patch from Bostik.
6191 * Imported Dotconf configuration library into lib/dotconf.
6192 This will be used to create the SILC configuration files later.
6193 It will appear in the distsribution after this commit.
6195 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * A big code auditing weekend happening. Auditing code for
6198 obvious mistakes, bugs and errors. Also, removing any code
6201 Removed files for being obsolete:
6203 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6204 inline in the file lib/silcutil/silcbuffer.h)
6206 o lib/silcutil/silcbufutil.c (the header has inline versions)
6208 Changed code to fix possible error conditions:
6210 o The buffer formatting routines now check that the destination
6211 buffer really has enough space to add the data. This applies for
6212 both buffer formatting and unformatting
6213 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6214 unformatting was changed to accomodate following rules:
6215 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6216 sent to the function while XXX_*STRING will not allocate or copy
6217 the data into the buffer. Instead it sets the pointer from the
6218 buffer into the pointer sent as argument (XXX_*STRING used to
6219 require that the pointer must be allocated already). This change
6220 makes this whole thing a bit more consistent and more optimized
6221 (note that the data returned in the unformatting with XXX_*STRING
6222 must not be freed now). The routines return now -1 on error.
6224 o Tried to find all code that use buffer_format and buffer_unformat
6225 and added return value checking to prevent formatting and
6226 especially unformatting errors and possible subsequent fatal
6229 o Changed ske->x and ske->KEY to mallocated pointers in
6230 lib/silcske/silcske.h. Fixed possible data and memory leak.
6232 o Added return value checking to all *_parse* functions. Fixed
6233 many memory leaks as well.
6235 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6236 so that buffer overflows would not happen. All code now also
6237 checks the return value as it can fail.
6239 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6241 * Added reconnection support to server if the normal server looses
6242 its connection to the router (for example if router is rebooted).
6243 The server performs normal reconnection strategy implemented
6244 to the server. Affected file silcd/server.c.
6246 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6248 * Added new packet type SILC_PACKET_SET_MODE that is used to
6249 distribute the information about changed modes (for clients,
6250 channels and clients channel modes) to all routers in the
6251 network. Updated the protocol specification accordingly.
6253 Added functions into silcd/packet_send.c and
6254 silcd/packet_receive.c: silc_server_send_set_mode,
6255 silc_server_set_mode.
6257 Added new files silcmode.[ch] into lib/silccore that implements
6258 the encoding and decoding of Set Mode Payload. Added new type
6259 SilcSetModePayload. Moved the definitions of different modes
6260 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6262 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6264 * Oops, a little mistake in server's connection authentication
6265 protocol. The protocol is not ended with FAILURE but with
6266 SUCCESS if the authentication is Ok. :) Affected file is
6269 * Implemented NICK_CHANGE notify handling in server in the file
6270 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6271 the local clients on the channel. After the changing nickname
6272 in router environment snhould work and the [<unknown>] nickname
6273 should appear no more.
6275 The silc_server_replace_id function that receives the Replace ID
6276 payload now sends the NICK_CHANGE notify type also in the file
6277 silcd/packet_receive.c
6279 * Changed WHOIS and IDENTIFY command to support the maximum amount
6280 of arguments defined in protocol specs (3328 arguments). This
6281 fixed a bug that caused problems when there were more than three
6284 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Added extra parameter, command identifier, to the
6287 silc_client_send_command so that explicit command identifier
6290 Changed that ID list routines uses specific command identifier
6291 when sending WHOIS/IDENTIFY requests to the server so that they
6292 can be identified when the reply comes back.
6294 Affected files lib/silcclient/command.[ch],
6295 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6297 * Added `sender' argument to silc_server_packet_send_to_channel
6298 to indicaet the sender who originally sent the packet to us
6299 that we are now re-sending. Ignored if NULL. Affected file
6300 silcd/packet_send.[ch].
6302 * Added some server statistics support in silcd/server_internal.h
6303 SilcServerStatistics structure and around the server code. Also
6304 send some nice statistics information when client is connecting
6307 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6309 * Fixed channel ID decoding in server's JOIN command reply in
6310 silcd/command_reply.c
6312 * Fixed braodcasting of replace ID payload to not to send it if
6313 we are standalone server in silcd/packet_receive.c.
6315 * Fixed all channel message sending routines to not to send
6316 packets to clients that has router set, since they are routed
6317 separately in the same function earlier. Affects file
6318 silcd/packet_send.c and all channel packet sending functions.
6320 * In USERS reply, res_argv[i] are not allocated, the table
6321 is allocated. Thus changed that free the table, not its
6324 * In server's whois_check and identify_check if the client is
6325 locally connected do not send any WHOIS commands - they are not
6328 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6330 * Fixed some minor bugs in client when sending WHOIS command. The
6331 arguments was in wrong order.
6333 * Removed statis function add_to_channel from server in
6334 silcd/command.c that was previously used with the joining but
6337 * Tested USERS command in router environment successfully with two
6338 routers, two servers and two clients.
6340 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6342 * Reorganized the USERS command and command reply in client library
6343 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6344 When the command is given by user we register a pending command
6345 callback that will reprocess the command after the reply has been
6346 received from the server. When reprocessing the packet we then
6347 display the information. Thus, the USERS information is displayed
6348 now in the command callback instead of in the command reply
6349 callback. The processing of the command is same as previously
6350 when server has sent the command reply in the JOINing process.
6352 * Added to USERS command in silcd/command_reply.c to join the client,
6353 we didn't use to know about, to the channel after we've created
6354 a client entry for it. Also, for clienet we did know already still
6355 check whether it is on the channel or not and add it if not.
6357 * Removed silc_server_command_join_notify as the function and its
6360 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6362 * Changed the client's pending command handling to the same as the
6363 server's pending command handling. It is also now possible to
6364 execute command reply functions from other command reply
6365 function as the function callbacks for commands and command
6366 replies are one and same. The pending commands are not static
6367 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6368 in client connection context. Thus, pending commands are server
6369 connection specific as it is convenient.
6371 Changed the function silc_client_command_pending and
6372 silc_client_command_pending_del and added new function
6373 silc_client_command_pending_check. Removed the
6374 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6377 * Added cmd_ident, current command identifier, to the client
6378 connection context in lib/silcclient/client.h to keep track on
6379 command identifiers used in command sending. Client's command reply
6380 function handling now supports the mandatory command identifiers.
6382 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6383 funtions in client to fully support pending command callbacks.
6385 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6386 as one of the arguments to the application in the command reply
6389 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6390 before first releasing SILC but came back. Now it is removed again
6391 and should come back nomore. The FORWARDED flag was used only
6392 by the JOINing procedure by forwarding the command packet to router.
6393 Now, the JOINing procedure has been changed to more generic (due
6394 to various router environment issues) and FORWARDED is not needed
6395 anymore for anything. The protocol specification is yet to be
6398 Now, removed silc_server_packet_forward from server and the flag
6399 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6401 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Renamed NAMES command to USERS command. The NAMES was named that
6404 due to historical reasons. Now it is renamed. Also, rewrote
6405 parts of the USERS command. The nickname list is not sent anymore
6406 by the server. Only Client ID and mode lists are sent in the USERS
6407 command. Changed this also to the protocol specification.
6409 The client now resolves the names and stuff after it receives
6410 the USERS list from the server when joining to the channel.
6412 * WHOIS and IDENTIFY commands has been changed to support multiple
6413 Client ID's per command. One can now search for multiple users
6414 in the network by sending only one WHOIS or IDENTIFY command.
6415 Changed the code and the protocol specifications.
6417 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6418 uses silc_server_command_whois_parse to parse the request. */
6420 * If normal server, do not parse the WHOIS and IDENTIFY requests
6421 before sending it to the router. Saves some time.
6423 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Fixed JOIN command on client library. Wrong number of arguments
6426 used to crash the client.
6428 * Added silc_server_channel_has_global function to check whether
6429 channel has global users or not.
6431 * Added silc_server_channel_has_local function to check whether channel
6432 has locally connected clients on the channel.
6434 * The silc_server_remove_from_one_channel now checks whether the
6435 channel has global users or not after given client was removed from
6436 the channel. It also checks whether the channel has local clients
6437 on the channel anymore. If it does not have then the channel entry
6438 is removed as it is not needed anymore.
6440 * The silc_server_notify now checks on JOIN notify whether the joining
6441 client is one of locally connected or global. If it is global then
6442 the channel has now global users on the channel and that is marked
6443 to the channel entry. Also, it now saves the global client to
6444 global list who is joining and JOINs it to the channel. This is
6445 for normal server, that is.
6447 Changed silc_server_send_notify_on_channel,
6448 silc_server_packet_relay_to_channel and
6449 silc_server_packet_send_to_channel check if we are normal server
6450 and client has router set (ie. global client) do not send the
6451 message to that client, as it is already routed to our router.
6453 * Implemented LEAVE notify type handling in silc_server_notify
6456 * Tested LEAVE command in router environment successfully. Tested
6457 with two routers, two servers and two clients.
6461 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6463 * Implemented SIGNOFF notify type handling in silc_server_notify
6466 * silc_server_remove_id now removes the client entry from all channels
6467 it has joined and thusly sends SIGNOFF notify type.
6469 * Rewrote the NAMES list generation in server by removing two excess
6470 loops. The lists are created now inside one loop.
6472 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6474 * silc_server_remove_channel_user checks now also global list
6475 for channel and client.
6477 * silc_server_new_channel_user checks now both local and global
6478 list for channel and client. Fixed a bug in client id decoding.
6479 Used to decode wrong buffer.
6481 * silc_server_channel_message checks now both local and global
6482 list for channel entry.
6484 * Tested channel joining (hence JOIN) in router environment
6485 successfully. Tested with two routers, two servers and two
6488 * Tested channel message sending in router environment successfully.
6490 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Added silc_server_save_channel_key into server.[ch] to save the
6493 received channel key in Channel Key payload processing. It is
6494 also used in JOIN command reply handling.
6496 Equivalent function silc_client_save_channel_key added into
6497 client.[ch] into client library.
6499 * Changed JOIN command reply to send information whether the channel
6500 was created or not (is existing already) and the channel key
6501 payload. Changed protocol specs accordingly.
6503 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6504 the request was sent by ID and not by nickname. Crashed on
6507 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6509 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6510 now correctly save the received data.
6512 * silc_server_free_sock_user_data now notifies routers in the
6513 network about entities leaving the network.
6515 At the same time implemented functions silc_server_remove_id
6516 and silc_server_send_remove_id to receive and send REMOVE_ID
6517 packets. The packet is used to notify routers in the network
6518 about leaving entities. The ID removed will become invalid in
6521 * Added function silc_idlist_del_server into server. Removes and
6522 free's server entry from ID list.
6524 * silc_server_private_message function now checks, if we are router,
6525 that the destination ID really is valid ID, naturally.
6527 * In router when NEW_ID packet is received (for new client) the
6528 hash of the Client ID is saved in the ID Cache but the
6529 client->nickname is set to NULL, instead of putting the hash
6532 IDENTIFY command now also checks that client->nickname must be
6533 valid. If it is not if will request the data from the server who
6534 owns the client. Added new function
6535 silc_server_command_identify_check.
6537 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6538 to set the command to already allocated Command Payload.
6540 * Tested private message sending in router environment with two
6541 routers, two servers and two clients. Fixed minor bugs and now
6544 * Fixed segfault from client's NAMES command. Used to crash if
6547 * Forwarded packets must not be routed even if it is not destined
6548 to the receiver. Changed server code comply with this.
6550 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Added `require_reverse_mapping' boolean value to ServerParams
6553 structure. If TRUE (not default) the server will require that
6554 the connecting host has fully qualified domain name.
6556 If the reverse mapping is not required and hostname could not be
6557 found the IP address is used as hostname.
6559 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * Implemented version string checking to both client and server.
6562 The check is incomplete currently due to the abnormal version
6563 strings used in development version of SILC.
6565 * Changed all command functions in server to use the new
6568 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6570 * Changed char *data to unsigned char *data in ID Cache system to
6571 support binary data as ID Cache data. Changed code to support
6572 binary data in lib/silccore/idcache.c.
6574 * Renamed silc_server_packet_relay_command_reply to
6575 silc_server_command_reply as it is normal packet receiving
6576 function. Rewrote the function to accept command replys for
6577 servers and not only for clients.
6579 * Mark remote router always as registered server if we are connecting
6580 to it. Otherwise, commands sent by the router to us are ignored.
6582 * All ID List find routines now returns the ID Cache Entry pointer
6583 as well if requested.
6585 * WHOIS command works now in router environment, tested with two
6586 routers, two servers and two clients.
6588 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6589 in router environment (as it is almost equivalent to WHOIS) but
6590 hasn't been tested thoroughly. Added new functions:
6592 silc_server_command_identify_parse
6593 silc_server_command_identify_send_reply
6594 silc_server_command_identify_from_client
6595 silc_server_command_identify_from_server
6597 * Disabled route cache adding because adding two different ID's with
6598 same IP replaces the old cache entry thus giving wrong route.
6599 The entry->router->connection is always the fastest route anyway
6600 so route cache may not be needed. Of course, new routes maybe
6601 established after receiving the ID when the entry->router->connection
6602 might not be anymore the most optimal.
6604 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Add route cache for received ID for fast routing.
6608 * Added silc_server_packet_route to route received packet on router
6609 that is not destined to us.
6611 * Renamed silc_server_get_route to silc_server_route_get.
6613 * Added id_string and id_string_len fields into SilcServer to
6614 include encoded ServerID for fast comparing without excess
6615 encoding of the ID's.
6617 * Cleaned up WHOIS command on server side. Added following static
6620 silc_server_command_whois_parse
6621 silc_server_command_whois_check
6622 silc_server_command_whois_send_reply
6623 silc_server_command_whois_from_client
6624 silc_server_command_whois_from_server
6626 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6627 arguments in command replies. All command functions should be
6628 updated to use this macro.
6630 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6632 * Minor typo fixes on command reply handling on server.
6634 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6636 * Added silc_server_command_add_to_channel internal routine to add
6637 the client to the channel after router has created the channel and
6638 sent command reply to the server.
6640 * Added generic silc_server_send_command to send any command from
6643 * Use static buffer with ID rendering instead of duplicating data.
6645 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Fixed a channel user mode bug when joining to a channel server gave
6648 everybody channel founder rights, oops.
6650 * We mark ourselves as the router of the incoming server connection
6651 if we are router ourselves. This way we can check in some packet
6652 sending functions whether it is locally connected server. For
6653 incoming router connections we put NULL.
6655 * For router sending packets locally means now always sending the
6656 packet cell wide; to local clients and local servers. For normal
6657 server sending packet locally means sending it to only local
6660 * Fixed the JOIN command to really work in router environment. If the
6661 channel is created it is always created by the router. Router is
6662 also responsible of making the initial joining to the channel,
6663 sending JOIN notify to the sending server and distributing
6664 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6665 does not exist server doesn't do anything else but forward the
6666 command to the router which performs everything.
6668 * Added silc_server_send_channel_key function to send the Channel Key
6671 * Added silc_server_create_channel_key to create new channel key. The
6672 channel key is now re-generated everytime someone joins or leaves
6673 a channel, as protocol dictates. Note: channel->key_len is the
6676 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6678 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6679 packet_receive.[ch] to separate packet sending and receiving
6680 routines. The server.[ch] now includes everything else including
6681 actual packet processing (writing and reading data) and other
6684 Renamed silc_server_private_message_send_internal to
6685 silc_server_send_private_message. The routine is still though
6686 used only to relay private messages as server does not send
6687 private messages itself.
6689 Renamed silc_server_new_channel to silc_server_create_new_channel
6690 and added new function sicl_server_new_channel that handles the
6691 incoming New Channel packet. Added also new sending function
6692 silc_server_send_new_channel to send New Channel Payload.
6694 * Added new function silc_server_notify to process incoming notify
6695 packet to the server/router. Server may then relay the notify
6696 to clients if needed.
6698 * Added new function silc_server_new_channel_user to process incoming
6699 New Channel User packet. Router will redistribute the packet and
6700 send JOIN notify to its local clients and locally connected servers
6701 if needed. Normal server will send JOIN notify to its local client
6702 on same channel when received this packet. Added also corresponding
6703 sending function silc_server_send_new_channel_user to sent the
6706 * Added boolean route argument to send_notif_to_channel and
6707 packet_send_to_channel functions to attempt to route the packet
6708 if it is TRUE and send only locally if it is FALSE.
6710 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6712 * silc_server_replace_id now broadcasts the received replace ID
6713 packet if it is not broadcast packet already. The router must
6714 broadcast to inform other routers about changed ID.
6716 * Added backpointer to server's router into SilcServer context in
6717 silcd/server_internal.h.
6719 * Fixed silc_server_packet_broadcast to send correct broadcast
6722 * The channel key is now distributed to the local client as soon
6723 as it is received from the router (in router environment) so that
6724 no other packet may be sent for the channel until client has
6727 * silc_server_remove_channel_user now broadcasts the received
6728 Remove Channel User packet if it is not broadcast packet already.
6729 The router must broadcast to inform other routers about removed
6732 * Added users field into SilcPacketContext that is a reference count
6733 of the context. One can increase the reference count by calling
6734 silc_packet_context_dup which is now changed to just increase the
6735 reference count instead of duplicating the data. The reference
6736 count is decresed by calling silc_packet_context_free that will
6737 free the data after the reference count hits zero.
6739 For now on the packet context and everything allocated into it
6740 (including the raw packet from network) must be freed by calling
6741 the new silc_packet_context_free function. Added also new function
6742 silc_packet_context_alloc that must be used now to allocate the
6743 context. This also means that if a routine is asynchronous from
6744 silc_[client/server]_packet_parse_type the packet context must
6745 be duplicated by calling silc_packet_context_dup. Otherwise it
6746 gets free'd after silc_[client/server]_packet_parse_type returns.
6747 Also, one must remember that if packet is duplicated then its
6748 reference count must be decresed by calling the free function as
6749 many times as it was duplicated.
6751 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6752 from both client and server.
6754 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Made joining to a channel working in router environment.
6758 * Cleaned up JOIN command on server side and create function
6759 silc_server_command_join_channel internal routine to make the
6762 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6764 * Changed silc_command_pending list to SilcDList. Also, added
6765 `ident' field to SilcServerCommandPending structure to identify
6766 the reply and to call correct callback.
6768 Added silc_server_command_pending_check function to replace the
6769 corresnponding macro. The silc_command_pending list is not
6772 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6773 to set identifier to previously allocated Command Payload. It
6774 is used to set identifier for command when resending Command
6777 * Added silc_command_payload_encode_payload to encode Command
6778 Payload buffer from SilcCommandPayload structure.
6780 * Added silc_argument_payload_encode_payload to encode Argument
6781 payload buffer from SilcArgumentPayload structure.
6783 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6785 * Changed WHOIS command to support router connection on server side.
6786 The whois request is always sent to router unless the server is
6787 standalone server. After server has received the reply from the
6788 router will it send the reply to the client.
6790 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6791 broadcast received broadcast packet. The function is used only
6792 by router. The broadcast packet is always sent to the router's
6795 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6796 render given ID to printable string, for log files for example.
6798 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6800 * Made basic router to router connections working. At least they
6801 can now connect to each other but nothing really works the way
6802 they are supposed - yet.
6804 * Added new initiator token to RouterConnection configuration
6805 file in silcd/serverconfig.[ch]. It is used to tell whether we
6806 are the initiator to the remote router or whether we'll expect
6807 the other end to connect.
6809 * Moved registering of listener task to silc_server_init, hence
6810 the server starts listenning as soon as it is run, even if it
6811 does not have connections to other routers. Let's see how well
6814 * Changed default connection retry timeouts for more suitable in
6817 * Removed cipher and such arguments from silc_idlist_add_client
6818 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6819 Added new function silc_idlist_add_data to add the keys and stuff
6822 * Added SilcIDListData structure and added it to SilcClientEntry
6823 and SilcServerEntry as their first field in the structure. This
6824 way we can explicitly cast the ID entries to the SilcIDListData
6825 structure and get common data for the entries. In past, we had
6826 to first check what type of connection it is and then cast it to
6827 correct ID entry type. Now, we can directly cast the opaque
6828 pointer to the SilcIDListData (no matter what ID entry it actually
6829 is) and get the data needed.
6831 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6833 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6834 in some circumstances even if threre were timeout tasks, though not
6835 IO tasks, but tasks anyway. Now fixed.
6837 * Defined SilcServerConnection structure to hold connection specific
6838 stuff about directly connected servers and routers. The definition
6839 is currently in silcd/server_internal.h. I thought about having
6840 a bit more important role fro this struct but for now it is used
6841 only when connecting to other server (or router actually).
6843 * Added connecting retry support in server when connecting to
6844 router(s). The retry feature implement exponential backoff
6845 algorithm. Also, added SilcServerParams structure to hold default
6846 parameters for server. For now, it include these retry settings
6847 and are hard coded. After server is moded to be as Silc Server
6848 Library this structure will be more important.
6850 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6852 * Changed client librarys channel->clients table to SilcList and
6853 changed code accordingly.
6855 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6857 * Changed client's channel table to SilcList and changed code
6858 accordingly. Also changed SilcChannelClientEntry to include back-
6859 pointer to the channel so that client entry can use that structure
6860 as list as well and we have fast cross-reference to the channel.
6861 This change dramatically decreased the complexity of channel
6862 handling with client entry and vice versa (removed one extra
6863 loop when searching for channel entry from many functions).
6865 * Changed server->sim from table to SilcDList and changed code
6868 * NAMES command can now be used from user interface. It will show
6869 the user list on the channel, neatly.
6871 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6872 Code now saves realname of the user if it becomes available.
6874 * Renamed configure.in to configure.in.pre and made ./prepare
6875 script to automatically add correct version string to
6876 configure.in which it creates from configure.in.pre.
6878 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6880 * NAMES command reply now shows users mode with the nickname when
6883 * Moved silc_client_ch[u]mode[_char] functions from
6884 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6885 place sucks, they are utility functions and should be in some
6888 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6890 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6893 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Added TRQ (efficient deque and list library) into lib/trq. This is
6898 a very good list library that is currently used in the SILC. Defined
6899 SilcList API over the library because I didn't like the API very
6900 much. See lib/trq/silclist.h for the API and examples of how to
6901 use the API. Fixed various places in the code to use the new
6902 SilcList API. The SilcList is meant for lists that has a structure
6903 already defined as a list. It is not suitable to add just some
6904 context to the list (in TRQ, the context is the list actually).
6906 So, I defined SilcDList that can be used for the purpose where
6907 predefined list structure does not exit. This can be used as
6908 such list. Now some context just can be added to the SilcDList.
6909 Currently this list is not used in the SILC just yet, though there
6910 are a lot places where this can replace dynamically allocated
6911 tables and I will fix these places, later, to use SilcDList.
6912 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6913 and use TRQ internally).
6915 Also fixed some annoying warning messages that the original TRQ
6916 code generated. Also minor changes to TRQ's Makefile.in.
6918 * Added support for querying by Client ID to both WHOIS and
6919 IDENTIFY commands into server, as required by the protocol.
6921 * Removed method function pointers from SilcBuffer structure. They
6922 weren't used to anything and just increased the context size for
6923 no good reason. This change also made silc_buffer_alloc and
6924 silc_buffer_free functions inline functions.
6926 * Disabled command flooding detection support until it's fixed so
6927 that it accepts commands in but does not execute them more than once
6930 * Added silc_net_localhost(), to return local hostname, into
6931 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6932 that must be initialized before calling silc_client_init.
6934 * Added new function: silc_server_send_notify_on_channels to send
6935 notify messages to all channels client has joined. It is assured
6936 that the message is sent only once per client.
6938 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6939 lib/silcutil/silcutil.[ch] as silc_format function. The new
6940 function is generic and is used by server as well, not only by
6941 the logging routines.
6943 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6944 the provided version string was not acceptable. Added new function:
6945 silc_ske_check_version into lib/silcske/silcske.h. The function
6946 must be implemented by the application (client or server) and it
6947 does not reside in the SKE library. The function checks the version
6948 string remote end sent.
6950 * Added back pointers (to opaque context and to SilcSocketConnection)
6951 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6953 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6954 duplicate packet context structure.
6956 * Changed `notify' client operation to send same arguments as client
6957 receives from server except for ID's. ID's are mapped to correct
6958 ID entry and that is returned. Also, if channel entry is not sent
6959 by server but the notify is for channel the channel entry is sent
6960 to application (otherwise application doesn't know that it is for
6961 channel (library gets it from packet's Destination ID)).
6963 * Added silc_client_remove_from_channels into client library to
6964 remove a client from all channels it has joined to. Used when
6965 received SIGNOFF notify from server. Added also new function
6966 silc_client_replace_from_channels to replace old ID entry with
6967 new ID entry on all channels. Used when received NICK_CHANGE
6970 * Fixed ID Cache list handling in silc_idlist_get_client in
6971 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6972 to get (or query) client by ID.
6974 * Updated TODO list.
6976 * Added connection authentication status message defined by the
6977 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6978 support for these into the code in client and server side.
6980 * Added generic function silc_client_send_command to send any command
6981 with variable argument list. Application should use this function
6982 to send commands if the command functions provided by the library
6983 does not suite for the application's user interface needs.
6985 * Added new `failure' client operation. Application is notified about
6986 received failure packet if client is executing a protocol. In this
6987 case the protocol's execution has failed.
6989 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6990 is required by the protocol.
6992 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6993 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6996 * Added status flag to SilcSKE object to indicate realtime status
6997 of the SKE protocol.
6999 * Application receives now exactly same command reply arguments as
7000 the library receives from server. However, if ID is received the
7001 corresponding ID entry is returned to the application (eg. Client
7002 ID is mapped to correct SilcClientEntry entry and that is returned).
7003 Changed command_reply client operation due to this change.
7005 * Changed all ID's in commands and in command replys as ID Payloads.
7006 Change affected both client and server side codes.
7008 All ID's sent in SILC network (with execption of ID's in SILC
7009 Packet header) are sent in ID Payload to support variable length
7012 * Server now notifies nick changes and notifies all clients on
7013 the channels about the new nickname (about the new Client ID,
7016 * Implemented CMODE command to change channel modes. Supports all
7017 channel modes defined by the protocol specs except ban and invite
7018 lists. (Also, private channel key mode is supported but support for
7019 setting private channel key in client is missing, thus, this mode
7020 has no effect on client side (except that server requires that the
7021 client uses private channel key and normal channel traffic does not
7024 Also, invite mode works per se, but INVITE command does not work
7025 yet correctly, so you can set channel as invite only channel but
7026 inviting clients to the channel does not work (it is yet to be
7027 thought what's the best way to do it).
7029 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7030 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7031 Implemented CUMODE command to change user's mode on the channel.
7032 Supports all modes defined by the protocol specs.
7034 * Added NAMES command reply to return users modes on the channel.
7036 * Removed unnecessary and slow ciphers from lib/silccrypt.
7038 * Set SO_KEEPALIVE option to connection sockets by default.
7040 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7042 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7043 redefined the Notify Payload into protocol specs.
7045 * Added silc_id_payload_parse_id to get ID directly from raw
7048 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7050 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7051 accept searching by Client ID as well.
7053 * Added support for LEAVE and SIGNOFF notify types in client library.
7055 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7056 to parse ID Payload from raw data.
7058 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7060 * Added flags parameter into silc_ske_assemble_security_properties
7061 function in lib/silcske/silcske.[ch].
7063 * Changed notify client operation to fit better for notify messages
7064 sent by server. The notify payload received from server is now
7065 passed to the application (after parsing it to SilcNotifyPayload).
7066 It is application's responsibility to retrieve the arguments
7067 from the payload and show the message the way it wants. The message
7068 sent by server is implementation specific.
7070 * Changed public keys to comply with the protocol specification.
7071 Old public keys are not supported anymore and are not compatible.
7073 * Removed nickname from Channel Payload as the latest draft removed
7074 it. The client must resolve the nickname from the NAMES command
7075 reply received when it joined the channel.
7077 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7079 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7081 * Fixed some errors in protocol specification drafts.
7083 * Created lib/silccore/silcnotify.c to implement Notify Payload
7084 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7085 generic payloads described by protocol specifications. The file
7086 includes implementations for ID Payload and Argument Payload.
7088 * Changed Command Payload implementation to use the new Argument
7089 Payload. Changed command_xxxx_payload to command_payload_xxxx
7090 to comply with SILC coding conventions.
7092 * Added suppport for Argument Payload handling in Notify Payload
7093 implementation as protocol requires it. Added the new support
7094 into server and client lib as well.
7096 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * Added support for multiple nicknames on same channel. [n] is
7099 added locally to the nickname if there are more than one same
7100 nicknames on the channel.
7102 * Server now sends all nicknames that matched WHOIS request.
7103 Client also shows the list received from server.
7105 * Added TOPIC command to client side. User can now set and show
7106 current topic on channel.
7108 * Added MOTD command to client and server. Also, server sends the
7109 motd when client connects to the server.
7111 * Changed version strings to comply ISO 8601.
7113 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7115 * Fixed protocol error handling in client library. It should now
7116 cope even if the SKE fails for some reason.
7118 * Made new protocol specification drafts for submitting to IETF.
7120 * Implemented TOPIC command to server in silcd/command.c.
7122 * Added two new notify types into lib/silccore/silcnotify.h:
7123 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7124 notify nickname change and topic setting/change on a channel.
7126 * API change of command_reply operation in client library. The
7127 application gets now the status type received from server as well.
7129 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7131 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7133 * Cras fixed and optimized the packet handling even further and
7134 it should work now. Minor change to the prototype of function
7135 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7137 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7139 * Added new function into lib/silcutil/silcschedule.[ch]:
7140 silc_schedule_with_fd to select() a specified fd. The function
7141 returns after timeout expires or data arrives or goes. The
7142 function is used by packet routines to wait that all data is
7143 received from network.
7145 * Fixed data reading from network in lib/silccore/silcpacket.c.
7146 The code now assures that all data is read from the fd and then
7147 continues packet processing. This was a bug fix since the code
7148 used to drop some data in some circumstances.
7150 * Added new function into lib/silcclient/client.[ch]:
7151 silc_client_start_key_exchange to start key exchange after
7152 connection has been established to server. The code internally
7153 now uses this funtion but its main purpose was to provide it
7154 for applications that perform their own connecting. After
7155 application has created a connection it merely calls this
7156 function to start the key exchange between client and server.
7157 The library takes care of everything else after that.
7159 Updated also lib/silcclient/README to explain the usage of
7162 * Do not send to application information that connection has
7163 been established. Application gets notified it by connect
7166 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7168 * Applied cras's patch to add silc_schedule_one function. The
7169 function runs scheduler once and returns.
7171 * Fixed the scheduler after cras messed it up. The timeout
7172 handling works now as it's supposed to work.
7174 * Added into lib/silccore/ silcnotify.h to include notify
7175 message types support. Changed silc_server_send_notify*
7176 functions, in server.[ch], to support those new notify types.
7177 Added the support for the notify types into client library,
7178 as well. Added new notify client operation into ops.h in
7181 * Changed silc_server_packet_send_to_channel to send normal
7182 packets instead of just channel message packets. The function
7183 is now used to send the notify packets to channels. It is not
7184 used to send channel message packets anymore, as server never
7187 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7188 va_arg()s as it seems to require it nowadays. I guess, if SILC
7189 is compiled with older va_arg() the new code should work anyway.
7191 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7193 * Splitted core library. Core library (lib/silccore) includes
7194 now only SILC protocol specific core (and common) components.
7195 Created new utility library (lib/silcutil) that includes more
7196 generic purpose stuff. The stuff for util library was taken
7197 from the old core library. This was minor and easy split.
7199 * Created SILC Client Library (lib/silcclient) that includes
7200 implementation of the SILC client without user interface. This
7201 was major move from silc/ directory. The code has been changed
7202 so that it is transparent towards the user interface. The
7203 silc/ directory includes now the same user interface as before
7204 and it uses the new client library. Read lib/silcclient/README.
7205 Basicly, the client library performs everything else related
7206 to SILC except user interface handling. Also, configuration
7207 files are considered to be part of user interface and library
7208 does not handle them.
7210 This change also changed a lot of structures, function naming etc.
7211 Most important change was that SilcClientWindow object was
7212 renamed to SilcClientConnection in the client library. Created
7213 also new file lib/silcclient/ops.h. Also added new files
7214 silc/local_command.[ch] and silc/client_ops.[ch].
7216 All these changes were made to make it easier for user interface
7217 designers to create what ever user interface for the SILC client
7220 It is also expected that the server will be moved to lib
7221 directory as well and SILC Server Library will be created;
7222 sometimes in the future.
7224 * Removed Local commands from lib/silccore/silccommand.h as
7225 they are application specific and new client library does not
7226 handle any of those anymore.
7228 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7229 old client implementation in silc/.
7231 * Added support for callback functions in SILC_LOG_* macros.
7232 Application can now set its own callbacks that will be called
7233 instead of using the default functions that will always print
7234 the debug messages to stderr (or stdout). Also, debugging can
7235 now be disabled by setting silc_debug to FALSE and re-enabled by
7236 setting it to TRUE. Note, that logging will still work even
7237 if debugging is disabled.
7239 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7240 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7241 silc_log_reset_debug_callbacks.
7243 * To enable debugging in silc client one must give now -d
7244 option on command line.
7246 * Changed silc_schedule_init to automatically allocate task queues
7247 if they are not allocated before calling it.
7249 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7251 * Added GMP 3.1 into math library.
7253 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7256 a channel in SILC network. The packet is used by servers and
7257 routers to notify other routers that user has left a channel.
7258 This little feature was missing until now. Added the feature
7259 to protocol specification as well.
7261 Added functions: silc_server_send_remove_channel_user and
7262 silc_server_remove_channel_user into server.[ch].
7264 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7265 lib/silccore/silcpacket.h. However, they are not implemented
7268 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7270 * Fixed joining to a channel and sending channel messages
7271 between server and router. The channel message sending should
7272 now work inside a cell.
7274 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7276 * Fixed the private message sending between server and router.
7277 The private message sending should now work inside a cell.
7279 * Added silc_server_replace_id into server.[ch] to replace
7280 existing ID in the SILC network.
7282 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7283 and silc_idlist_replace_server_id into idlist.[ch] in server.
7285 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7287 * Fixed the server to server connections. Server can again now
7288 connect to router. Router to router connections probably does
7291 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7293 * Added dynamic protocol registering support. Now protocols can
7294 registered and unregistered on the fly. Patch by cras.
7296 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7298 * Added lib/contrib directory to hold routines that some platforms
7299 don't have but are needed by SILC.
7301 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7302 into lin/contrib to provide getopt() and getopt_long() for
7303 those who don't have it.
7305 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7307 * Added AWAY command to client. When away message is set and
7308 client receives a private message packet the client automatically
7309 replies to the sender with the away message.
7311 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7312 bug seemed to be the cause of recent problems when compiling
7315 * Added version detection support to SKE protocol specification
7316 and added the new changes to the SKE implementation as well.
7317 There were other minor changes in the SKE protocol as well.
7319 Many changes in lib/silcske/silcske.[ch] and in
7320 lib/silcske/payload.[ch].
7322 * Added ^U functionality, clear input line. Patch from cras.
7324 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Mainly small bugfixes on core library. Fixed some debugging
7327 logging and buffer overflow in silclog.c.
7329 * Updated config.sub and config.guess on the distribution tree.
7331 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7333 * Added command lagging support in server. Client may execute
7334 commands now only once in two seconds.
7336 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7338 * Optimized packet reception. MAC computation and checking is now
7339 also more optimized. A lot previously duplicated code is now
7340 used as generic by both client and server.
7342 * Fixed key pair generation in clientutil.c
7344 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7346 * Added into lib/silccore/silcbufutil.[ch] new function;
7347 silc_buffer_realloc.
7349 * Moved generic packet sending/encryption functions to
7350 lib/silccore/silcpacket.[ch] from client and server. Some
7351 rewriting of the functions.
7353 * Moved all generic packet reception/decryption functions to
7354 lib/silccore/silcpacket.[ch] from client and server. The
7355 packet processing is now much cleaner in both client and server.
7356 These were major changes in both client and server.
7358 * Created many common functions in server to do packet sending.
7359 Previously code were duplicated a lot, this has been removed
7362 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7364 * Rewrote major parts of the ID cache system. Don't know
7365 whether it is better now or not but at least the API is more
7368 * Major rewrite on ID cache stuff on client because of the ID
7369 cache API changes. Added idlist.c to client.
7371 * Also major rewrite on ID cache stuff on server as well.
7372 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7373 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7374 in hand, instead they are all put into the ID cache system now.
7375 All server_idlist_* routines uses ID cache now instead of
7376 traversing its own lists (those lists does not exist anymore).
7377 SilcIDList though still exists. Also, SilcXXXEntry's are
7380 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7382 * Finally made the SKE implementation compliant to the protocol
7383 specification. All mp integers are now binary encoded as
7384 opposed being HEX encoded.
7386 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7389 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7390 functions: silc_[encode/decode]_pem. Also added function
7391 silc_encode_pem_file to PEM encode with newlines ('\n') for
7394 * SILC public keys are now encoded either PEM or binary. Same
7395 option is for private keys as well. By default private keys
7396 are binary encoded and public keys PEM encoded. Silly HEX
7397 encoding were removed.
7399 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7400 function to create fingerprints.
7402 * Fixed a bug in SHA1; does not change the original data anymore.
7404 * Partly implemented INFO command on client and server side.
7405 Fixed CLEAR command. Changes to SERVER command; show current
7406 server(s) when giving command without arguments. Added
7407 VERSION command to client.
7409 * Added check to server that unregistered connections cannot
7410 execute commands (unless it is specificly allowed).
7412 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7414 * Fixed screen refresh.
7416 * Fixed channel joining bug from client. On some circumstances
7417 client tried to join to a channel it had already joined.
7419 * Added public key verification process into client's protocol.c.
7420 The client now verifies the public key from user and saves
7421 it into ~./silc/serverkeys/ directory.
7423 Added into: clientutil.[ch]: silc_client_verify_server_key.
7425 * Changed SKE protocol's silc_ske_initiator_finish function
7426 to accept callback function that verifies the received public
7427 key. Removed old silc_ske_verify_public_key function.
7429 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7431 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7432 silc_pkcs_private_key[_data]_set.
7434 * Made the password and public authentication more cleaner in
7435 server's protocol.c.
7437 * Removed historic and obsolete protocol `channel_auth' from
7438 both client and server.
7440 * Removed wrong way of sending command status messages from
7441 server to client in server's command.c. The old way violated
7442 protocol specification.
7444 Changes to silccore/silccommand.[ch]: removed
7445 silc_command_encode_status_payload -> not needed anymore,
7446 changed silc_command_encode_payload_va to accept extra
7447 argument on variable argument list. The argument type must
7448 now be provided to the function. Also, added new function:
7449 silc_command_encode_reply_payload_va which is same as
7450 normal command_encode_payload_va except command status type
7451 is provided as extra argument.
7453 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7455 * Added ~./silc directory handling. The directory includes the
7456 public and private keys for the client.
7458 Added silc_client_check_silc_dir, silc_client_create_identifier
7459 and silc_client_load_keys.
7461 * Implemented SILC protocol compliant public key. Added public
7462 and private key saving to and loading from files.
7464 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7465 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7466 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7467 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7468 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7470 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7471 silc_pkcs_load_[public/private]_key.
7473 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7475 * Added silc_server_get_route (route.[ch]) to get connection
7476 data for the fastest route for given ID.
7478 * Implemented INVITE command on client and server. The command
7479 were re-defined in the SILC Protocol Specification and the
7480 implementation now complies with the specification.
7482 * Implemented PING command on client and server.
7484 * Implemented NAMES command on client and server. The server side
7485 supports currently only normal server not router server yet.
7486 Some changes to NAMES definition in SILC protocol specification.
7488 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7490 * Implemented LEAVE command on client and server.
7492 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7493 again. This change was made to the protocol as well. Server
7494 should not violate the protocol specification anymore.
7496 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7498 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7499 was tested. SOCKS4 was not but should work anyway.
