1 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added the deleting of server's own ID cache entry to the
4 silc_server_free function. Free also everything else that
5 has been allocated in silc_server_init. The affected file
8 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
10 * Added functions silc_parse_version_string, silc_version_to_num,
11 and silc_ske_parse_version to parse SILC protocol style version
12 strings. Affected files lib/silcutil/silcutil.[ch] and
13 lib/silcske/silcske.[ch].
15 * Added new configuration params: version_protocol, version_software
16 and version_software_vendor to specify what version the remote
17 host must at least be to be able to connect to server. The vendor
18 string can be regex matched too. Added new function
19 silc_server_connection_allowed to check maximum number of allowed
20 connections, and allowed versions for incoming connections.
21 Affected files are silcd/server.c, server_util.[ch] and
24 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
26 * Added preliminary support for signals in scheduler. The
27 signals we care about are now blocked always when the scheduler
28 is locked. This way we can synchronise the use of signal with
29 scheduler. It is guaranteed that when signal occurs the scheduler
30 is not locked, and thus new tasks can be safely added to the
33 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
34 to silc_schedule_internal_init and silc_schedule_internal_uninit.
35 Added new platform specific routines
36 silc_schedule_internal_signals_[un]block and
37 silc_schedule_internal_signal_[un]register.
39 Added new functions to SILC Schedule API:
40 silc_schedule_signal_[un]register. Each signal that application
41 is going to use should be registered to the scheduler.
43 Affected files are lib/silcutil/silcschedule.[ch],
44 lib/silcutil/*/silc*schedule.c.
46 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
48 * Check for unauthenticated client and server in the
49 silc_server_new_client and silc_server_new_server functions.
50 Affected file silcd/packet_receive.c.
52 * Added function silc_string_is_ascii to check whether given
53 string is 7-bit ASCII string. Affected files are
54 lib/silcutil/silcutil.[ch].
56 * Added function silc_id_is_valid_server_id into the
57 silcd/serverid.c and added checking for valid Server ID's in
58 silc_server_new_server. The Server ID must always be based
59 on the server's public IP address.
61 * Added logging of DISCONNECT packet message in the server.
62 Affected file silcd/server.c.
64 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
66 * Changed all library interfaces that use Global RNG to also
67 accept SilcRng as argument. Affected files are
68 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
69 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
70 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
71 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
74 * Added function silc_pkcs_generate_key to the
75 lib/silccrypt/silcpkcs.[ch] for applications so that they
76 don't need to do pkcs->pkcs->init calls anymore.
78 * Remove SilcSocketConnection from the SFTP API since it really
79 wasn't needed there. The application has the information
80 saved in its contexts anyway and the SFTP layer doesn't need
81 know about it. Affected files lib/silcsft/silcsftp.h and
82 lib/silcsftp/sftp_[server/client].c.
84 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
85 The SilcSimContext is not SilcSim.
87 * Fixed possible buffer overflows in silc_id_render in the
88 lib/silcutil/silcutil.c.
90 * On EPOC the global crypto module lists are not used at all
91 in the crypto library. Added support for using the constant
92 algorithm list on EPOC. Affected files are
93 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
96 * Fixed the handling of third parameter of KICKED notify, since
97 it was mistakenly updated to SILC Protocol 1.0 even though it
98 is to be included in 1.1. Since it is not in 1.0 it is not
99 mandatory, and this fix now handles it only if it is provided,
100 and it is not error if it is not provided. Affected file
101 lib/silcclient/client_notify.c.
103 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
105 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
106 client. Affected file irssi/src/silc/core/client_ops.c.
108 * Merged with Irssi 0.8.4 from irssi.org CVS.
110 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
112 * Check for valid socket connection in client entries before
113 sending any messages. Fixes a crash, but doesn't fix some
114 other underlaying bug that is lurking there. Affected
115 file silcd/packet_send.c.
117 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
119 * $usermode, $cumode and $cumode_space expandos shouldn't do
120 anything with non-SILC server records. Affected file
121 irssi/src/silc/core/silc-expandos.c
123 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
125 * Fixed the silc_net_check_[host/local]_by_sock to support
126 IPv6 bound sockets as well. Now they can return IPv6 addresses
127 as well. Affected file lib/silcutil/silcnet.c.
129 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
130 Affected lib/silcutil/unix/silcunixnet.c.
132 * Fixed ID rendering (at least on some platforms, not NetBSD)
133 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
135 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
137 * Added silc_hash_public_key and silc_hash_public_key_compare
138 functions to be used with SilcHashTable. They can be used to
139 hash public keys and compare public keys in hash table. Affected
140 file lib/silcutil/silcutil.[ch].
142 * Added support for specifying multiple public keys for Client
143 connection section in server configuration file. This makes it
144 possible to accept multiple public keys from same host, or to
145 make a section that accepts any incoming host, and have the
146 accepted public keys listed in the section.
148 Added functions silc_sever_[find/get]_public_key, added the
149 support for this actually to all connection sections but only
150 the Client section is currently allowed to specify multiple
153 Affected files are silcd/server.c, server_internal.h,
154 command.c, protocol.c, server_util.[ch], packet_receive.c.
156 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
158 * Merged Irssi 0.8.2 from irssi.org CVS.
160 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
162 * If silc_debug is TRUE, also output standard logging messages
163 to stderr with the debug output.
165 Made silc_log_reset_all() flushing all channels before returning.
166 Also fixed some documentation typos.
168 Affected files are lib/silcutil/silclog.[ch].
170 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
172 * Fixed the server to check correctly the amount of connections
173 from single host, by checking also the type of the connection.
174 Fixed also the comparison of number of connections and number
175 of allowed connections. Affected files are silcd/server.c,
178 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
180 * Fixed the USERS command reply to save the user's mode on the
181 channel as well. Fixed JOIN command reply to check whether a
182 client is on channel already and not join it twice. Affected
183 file lib/silcclient/command_reply.c.
185 * Added new file silc-expandos.c into irssi/silc/core/ to return
186 various stuff for various signal for the statusbar etc. updating.
187 Now Irssi SILC client prints channel user modes etc. on the
190 * The user mode (like server/router operator changes) is now shown
191 on the Irssi SILC client's statusbar. The affected files are
192 irssi/src/silc/core/client_ops.c, silc-expandos.c.
194 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
196 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
197 to SILC_SCHEDULE_[UN]LOCK macros.
199 * Added more error printing to logs in server code. Affected
200 files silcd/server.c and silcd/protocol.c.
202 * Fixed -S option parsing in Irssi SILC Client. Affected file
203 irssi/src/silc/core/silc-core.c.
205 * Added silc_buffer_alloc_size function. Affected file is
206 lib/silcutil/silcbuffer.h.
208 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
210 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
211 constants. Affected files in
212 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
215 * Changed the internal SFTP Memory FS table to const. Affected

218 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
220 * Fixed the buffer formatting and unformatting routines to
221 check the size of 64 bits types with sizeof(). Affected
222 file is lib/silcutil/silcbuffmt.c.
224 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
226 * Removed 0.6.x backwards support.
228 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
230 * Changed all integer type names:
231 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
232 to avoid collisions with other libraries using same type names
235 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
237 * Added `prefer_ipv6' argument to the functions
238 silc_net_gethostbyname[_async]. If it is TRUE it will return
239 IPv6 address over IPv4. If FALSE IPv4 address is returned
240 even if IPv6 address was found. Affected files
241 lib/silcutil/silcnet.[ch].
243 * Added support silc_net_create_connection[_async] to fallback
244 to IPv4 address if IPv6 address could not be used (like if

257 application does not need to define them. Affected file
258 includes/silcincludes.h.
260 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
261 old name went against naming convention. Applications now
262 include "silcclient.h" instead of "clientlibincludes.h".
263 Removed includes/clientlibincludes.h, it is redundant now.
265 * Renamed includes/version.h to silcversion.h.
267 * Added really preliminary support for OS/2 into the util
268 library. Only thread & mutex API is implemented, others
269 are still to be implemented. Created the lib/silcutil/os2/
270 directory. Created also file includes/silcos2.h.
272 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
274 * Added preliminary BeOS support into the util library.
275 Created lib/silcutil/beos/, and implemented all the needed

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

299 to the lib/silcutil/silcbuffer.h.
301 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
303 * Added `user_count' to the SilcChannelEntry which now tells the
304 number of users on the channel. The user count is now saved
305 in normal server of global channels as well. Affected files
306 silcd/server.c, idlist.h, packet_receive.c and command.c.
308 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
309 include file utility functions.
311 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
312 instead of calling directly OS routines.

315 KICKED notify printing in Irssi SILC Client. Affected file
316 irssi/src/silc/core/client_ops.c.
318 * Fixed a NICK change bug in client library, to not recreate the
319 client_entry->channels hash table everytime nick is changed.
320 Affected file lib/silcclient/client.c.
322 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
324 * ROBOdoc documented the lib/silcske/silcske.h, and improved
325 the SKE interface a bit.
327 * Fixed padding problem in PKCS#1. The padding was not actually
328 random since the random number generator was used incorrectly.
329 This security bug affects only when encrypting with PKCS#1, and
330 it is not currently used at all in SILC. SILC only use signing
331 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
333 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

503 * Fixed the file transfer's key agreement payload to include
504 zero port also if the hostname is NULL because it could not
507 Call file transfer monitor callback now also if error occurs
508 during key agreement protocol.
510 Changed the silc_client_file_send interface to return the
511 SilcClientFileError instead of session id. The session ID
512 is returned into pointer provided as argument.
514 Check that the file exists locally before sending the
515 file transfer request at all.
517 Affected file lib/silcclient/client_ftp.c, silcapi.h.
519 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

529 file lib/silcutil/silclog.c.
531 * Fixed the channel message payload decryption in the function
532 silc_channel_message_payload_decrypt to not modify the original
533 buffer before it is verified that the message decrypted
534 correctly. Otherwise, next time it is called with correct
535 channel key it won't encrypt since the payload is corrupted.
536 Affected file lib/silccore/silcchannel.c.
538 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

546 Affected file lib/silcutil/silcnet.c.
548 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
550 * Fixed a bug in hash table internal routine for traversing
551 the table with foreach callback. The current entry may
552 become invalid in the callback but it was referenced after
553 the callback returned.
555 Do not allow auto rehashing of hash table during the
556 silc_hash_table_foreach operation, for same reasons as it is
557 not allowed for SilcHashTableList. Affected files are
558 lib/silcutil/silchashtable.[ch].
560 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
562 * Defined DLLAPI into silcincludes.h and silcwin32.h for
563 Win32 DLL. extern's in header files are now declared with
566 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
568 * Fixed private message handling. It used some old code that
569 caused the client to crash. Affecte file is
570 lib/silcclient/client_prvmsg.c.
572 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
574 * Added function silc_client_add_channel,
575 silc_client_replace_channel_id, and removed functions
576 silc_client_new_channel_id and silc_idlist_get_channel_by_id
579 * Added cross reference of the joined channels to the
580 SilcClientEntry, and changed the SilcChannelEntry's
581 users list to SilcHashTable. The affected files are
582 lib/silcclient/idlist.[ch].
584 * Fixed a bug in hash table tarversing. While the hash table
585 is traversed with SilcHashTableList the table must not be
586 rehashed. It is now guaranteed that auto rehashable tables
587 are not rehashed while tarversing the list. Also defined that
588 silc_hash_table_rehash must not be called while tarversing
589 the table. Added function silc_hash_table_list_reset that must
590 be called after the tarversing is over. The affected files are
591 lib/silcutil/silchashtable.[ch].
593 * Changed all hash table traversing to call the new
594 silc_hash_table_list_reset in server and in client library.
596 * Added function silc_client_on_channel to return the
597 SilcChannelUser entry if the specified client entry is joined
598 on the specified channel. This is exported to application as
599 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
601 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
603 * Fixed founder regaining problem with JOIN command on normal
604 server. The notify for mode change must be sent always and
605 not only if !cmd->pending. Affected file silcd/command.c.
607 * Fixed the WHOWAS command's reply sending to support the
608 lists correctly. Affected file silcd/command.c.
610 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
612 * When sending JOIN command to router for processing the
613 sender's old command identifier was not saved back to the
614 sender's command context, fixed now. The affected file is
617 * Create the key in JOIN command of the router did not return
618 the channel key, added check for this. Affected file is
621 * Fixed a channel ID update bug in JOIN command reply. Do
622 not directly upgrade the ID but call the function
623 silc_idlist_replace_channel_id if the ID was changed.
624 Affected file silcd/command_reply.c.
626 * Fixed memory leaks from command calling if it would fail.
627 Affected file silcd/command.c.
629 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
631 * Applied patches from cras:
633 Memory leak fixes around libaries, irssi window resize fix,
634 new silclist.h and silcdlist.h, all extern inline changed to
637 * Removed dotconf from lib/dotconf, not needed anymore.
639 * Removed TRQ from lib/trq, not needed anymore.
641 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
642 with server connections. Later this will be configurable
643 in config file after new config file is done. Affected file
646 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
648 * Fixed a crash in server related to channel announcements.
649 Affected file silcd/server.c.
651 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
653 * Fixed memory leaks in silc_server_create_new_channel*
654 functions. Affected file silcd/server.c.
656 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
657 which ID was changed. This way the router will send the
658 user list for the channel again, and server won't be in
659 desync in some rare circumstances. Affected file is
660 silcd/packet_receive.c.
662 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
664 * Check for NULL socket pointer in the function
665 silc_server_packet_send_to_channel_real. Affected file
668 * Fixed the BAN notify handling to correctly remove ban
669 list. Affected file silcd/packet_receive.c.
671 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
673 * Fixed some header addition to Toolkit distribution in
674 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
676 * Added lib/silcclient/client_ops_example.h as an template
677 file for application programmers to quickly start using
678 the SilcClientOperation functions in their application.
679 Updated the lib/silcclient/README as well to tell about this
680 nice file made available.
682 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
684 * Call silc_server_remove_from_channels when removing client
685 entry when NO_SUCH_CLIENT_ID was received. Affected file
686 is silcd/command_reply.c.
688 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
690 * Added server & router operator statistics updating. Affected
691 file silcd/packet_receive.c and silcd/command.c.
693 * Fixed the SERVER_SIGNOFF notify handling on normal server
694 not to save the history information for clients. Same was
695 fixed earlier in remove_clients_by_server function, but not
696 here. Affected file silcd/packet_receive.c.
698 * Raised the default connection-retry count from 4 to 7 in
699 server. Affected file silcd/server.h.
701 * Cancel any possible reconnect timeouts when we start the
702 key exchange. Affected file silcd/server.c.
704 * Do not reconnect on connection failure when SCONNECT was
705 given. Affected files silcd/server.[ch].
707 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
709 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
711 * Fixed the NICK command to always give the unformatted
712 nickname to the one giving the NICK command. If unformatted
713 nickname is cached already it will be formatted and the
714 local entry will always get the unformatted nickname.
715 Affected file lib/silcclient/idlist.c.
717 * Fixed some double frees from client library commands.
718 Affected file is lib/silcclient/command.c.
720 * Fixed CUMODE command in server to assure that no one can
721 change founder's mode than the founder itself, there was a
722 little bug. Affected file silcd/command.c.
724 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
726 * Removed the SilcClientCommandDestructor from the client
727 libary, it is not needed anymore. Affected files are
728 lib/silcclient/silcapi.h, command[_reply].[ch],
729 client_notify, idlist.c.
731 * Fixed GETKEY command to first resolve client, and then
732 resolve the server only if the client was not found, instead
733 of resolving both at the same time. Affected file is
734 lib/silcclient/command.c.
736 * Added silc_client_start_key_exchange_cb and lookup the
737 remote hostname and IP address before starting the key
738 exchange with server. The affected file is
739 lib/silcclient/client.c.
741 * The server's public key is now saved using the IP address
742 of the server and not the servername for the filename.
743 The hostname public key filename is checked as an fall back
744 method if the IP address based filename is not found.
746 Fixed the GETKEY command to save the fetched server key
749 Print the remote server's hostname now when new key is
750 received during connection process. Affected file is
751 irssi/src/silc/core/client_ops.c.
753 * Return always our own public key to the client if it asks
754 for it with GETKEY command. Affected file silcd/command.c.
756 * Removed the use_auto_addr variable from default config
757 file since it was in wrong section. Affected file is
760 * Fixed TOPIC_CHANGE notification to not route it when it
761 was sent using silc_server_send_notify_to_channel function.
762 Affected file silcd/command.c.
764 * Fixed silc_server_send_notify_kicked to send the kicker's
765 Client ID also, it was missing. Affected files are
766 silcd/command.c, silcd/packet_send.[ch].
768 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
770 * Do not save client history information in SERVER_SIGNOFF.
771 Fixes the bug in normal server that it does not detect
772 the client becoming valid after the server becomes back
773 online. Affected file silcd/server_util.c.
775 * Added `sock_error' field into the SilcSocketConnection
776 context. When error occurs during socket operation (read
777 or write) the error is saved. Added also new function
778 silc_socket_get_error to return human readable socket error
779 message. Affected files are lib/silcutil/silcsockconn.[ch],
780 lib/silcutil/unix/silcunixsockconn.c, and
781 lib/silcutil/win32/silcwin32sockconn.c.
783 * The server now prints the socket error message in the
784 signoff for client. Affected file silcd/server.c.
786 * Fixed the `created' channel information sending from router
787 to server in JOIN command. Checks now whether the channel
788 really was created or not and set it according that.
790 Fixed the JOIN command to use the client entry's current
791 ID during the joining procedure instead of the one it sent
792 in the command (it is checked though), since it can change
793 between the packet processing and command processing, and
794 would just case unnecessary pain in the client end. Affected
795 file silcd/command.c.
797 * Fixed a channel key payload sending to use correct channel
798 ID when the server was forced to change the channel's ID by
799 router. Router sent the key payload with the old Channel ID.
800 Affected file silcd/packet_receive.c.
802 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
804 * Call silc_server_save_channel_key only if the key payload
805 was provided in the JOIN command's command reply. Affected
806 file silcd/command_reply.c.
808 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
810 * Fixed silc_mp_sizeinbase to return the value correctly with
811 MPI. Affected file lib/silcmath/mp_mpi.c.
813 * Fixed the stop_server signal to correctly stop the scheduler
814 and gracefully stop the server when SIGTERM or SIGINT signals
815 are received. Affected file silcd/silcd.c.
817 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
819 * Simple handling of TERM and HUP signals. Also added some log
820 flushing call around. Affected file is
823 * Fixed small bugs in silclog.c. Now buffering output will take
824 effect after 10 seconds since startup: This will ensure that
825 no important startup messages are lost. Also output redirection
826 will preserve original format ([Date] [Type] message).
827 Affected file is lib/silcutil/silclog.c.
829 * Added two options to the config file, in the logging section:
830 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
831 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
833 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
835 * Do not print the warning about log files not being initialized
836 more than once to avoid excess logging. Affected file is
837 lib/silcutil/silclog.c.
839 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
840 the SIM copying in make install in Makefile.am.pre.
842 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
844 * Rewritten silclog APIs. Globally interesting changes follows:
845 silc_log_set_files() changed to silc_log_set_file().
846 silc_log_set_callbacks() changed to silc_log_set_callback().
847 ROBOdoc documented silclog header file.
848 SilcLogCb now returns bool to wether inihibit the default
849 handler or not (to keep the old behaviour return always TRUE).
850 The new APIs should also fix the problem of the
851 silcd_error.log file that was written in the current directory.
854 Log files streams will remain opened after silc_log_set_file()
855 call, means less CPU usage notably on high traffic servers.
856 File streams are now full buffered, and flushed to the disk
857 every 5 minutes, lesses HD activity and CPU usage.
858 Messages can be redirected, allowing admins to configure
859 one single logfile for all server messages.
860 the silc_log_quick global variable to activate fast-logging.
861 Affected files lib/silcutil/silclog.[ch]
863 * Changed some code to conform new silclog APIs. Affected
864 files are doc/example_silcd.conf.in, silcd/server.c
865 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
868 * Fixed a memory leak that could occur in some situations.
869 Affected file silcd/serverconfig.c.
871 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
873 * Added the silc_client_del_client to remove the client from
874 all channels as well. Affected file lib/silcclient/idlist.c.
876 * Fixed the client library to correctly remove the client
877 from all channels when the client entry is being destroyed.
878 Affected file lib/silcclient/client_notify.c, command.c.
880 * Added auto-nicking support to the client library. If the
881 applicatio now sets client->nickname it will be sent to the
882 server after connecting by the library. This way for example
883 SILCNICK (or IRCNICK) environment variables will have effect
884 and always change the nickname automatically to whatever
885 it is wanted. Affected file lib/silcclient/client.[ch].
887 * Renamed silc_server_command_bad_chars to the
888 silc_server_name_bad_chars and moved it to the
889 silcd/server_util.[ch]. Added also new function
890 silc_server_name_modify_bad to return nickname that
891 includes bad characters as new nickname without those
892 bad characters. This check and modify is now used in
893 silc_server_new_client when the username is initially set
894 as nickname, so it must be checked to be valid nickname.
895 Affected file silcd/packet_receive.c.
897 * The nickname length is now taken from the packet for real
898 and not trusted to strlen() since it clearly can return
899 wrong length for nickname including bad characters. This
900 also applies to channel names. Affected file silcd/command.c.
902 * Removed the lib/silcsilm/modules directory. Modules are now
903 compiled into the lib/silcsim. Fixed the copying of the
904 modules to follow symbolic links in Makefile.am.pre.
906 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
908 * Fixed silc_string_regexify list creation. Fixes bugs with
909 BAN and INVITE commands in server. The affected file is
910 lib/silcutil/unix/silcunixutil.c.
912 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
914 * Removed the command destructor entirely from the server's
915 command and command reply routines. It is not needed, and
916 its usage was buggy and caused crashes. Affected files are
917 silcd/command[_reply].[ch].
919 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
921 * Cancel protocol and NULL sock->protocol if timeout
922 occurred during protocol. Affected file silcd/server.c.
924 * Cancel protocol timeouts always before calling the final
925 callback, to assure that after final callback is called
926 no other state will be called for the protocol anymore.
927 Affected file silcd/protocol.c.
929 * Print error log if incoming connection configuration could
930 not be found. Affected file silcd/server.c.
932 * Fixed JOIN command to correctly save the founder mode
933 to the client on normal SILC server, when the channel
934 was created by the router. Affected file silcd/command.c.
936 * Fixed LIST command (hopefully) to send correct reply
937 packets. Affected file silcd/command.c.
939 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
941 * The silc_packet_receive_process now returns FALSE if the
942 read data was invalid packet, and TRUE if it was ok.
944 The server now checks that if unauthenticated connection
945 sends data and its processing fails the server will close
946 the connection since it could be a malicious flooder.
948 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
950 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
952 * Make sure the warning about error opening a log file is
953 printed only once and not everytime it fails (produces
954 too much useless log). Affected file lib/silcutil/silclog.c.
956 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
958 * Made the silc_server_daemonise() function more readable.
959 Affected file silcd/server.c.
961 * Pid file is now optional, the user may comment it out from
962 the config file. Removed define SILC_SERVER_PID_FILE, we
963 don't need a default any longer. Affected file
964 configure.in.pre, lib/Makefile.am.pre.
966 * Make some use of the pid file. The server now dies at startup
967 if it detects a valid pid file on his path. The server would
968 die anyway in this circumstance, because of the bind() failure.
969 Affected file silcd/silcd.c.
971 * No longer compiling lib/dotconf.
973 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
975 * Fixed JOIN command parsing not to crash. Affected file
976 lib/silcclient/command.c.
978 * Fied the NICK_CHANGE notify to add the new client entry
979 even it is resolved. This removes an <[unknown]> nick
980 thingy bug in the client. Affected file is
981 lib/silcclient/client_notify.c.
983 * Do not try to allocate 0 bytes (efence does not like it)
984 in lib/silccore/silccomand.c when encoding payload.
986 * Do not take IRCNICK as nickname in Irssi SILC client since
987 it is not possible to set nickname before hand connecting
988 the server (TODO has an entry about adding auto-nicking
991 * Changed the silc_server_command_pending to check whether
992 there already exists an pending entry with the specified
993 command, command identifier and pending callback. This is
994 to fix IDENTIFY and WHOIS related crashes that may register
995 multiple pending commands with same identifier. Affected
996 file silcd/command.c.
998 * Fixed the server to reconnect to the router even if it
999 was already reconnecting and EOF was received. This to
1000 fix a possibility that the server wouldn't ever try to
1001 auto-reconnect to the router. Affected file silcd/server.c.
1003 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1005 * Fixed the server's password authentication to use the
1006 length of the locally saved password, and not the one
1007 sent in the packet. Affected file silcd/protocol.c.
1009 * Fixed same password authentication problem in the
1010 Authentication Payload handling routines in
1011 lib/silccore/silcauth.c.
1013 * Yet another password authentication problem fixed with
1014 channel password handling in silcd/command.c.
1016 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1018 * If first character of string in silc_parse_userfqdn is '@'
1019 then do not parse it. Affected file is
1020 lib/silcutil/silcutil.c.
1022 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1024 * Fixed minor bug in IDENTIFY command reply sending, which
1025 caused various weird problems during JOIN when it was
1026 resolving names for users. Affected file silcd/command.c.
1028 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1030 * Fixed the IDENTIFY command reply sending to chech better valid
1031 clients. It was possible to send incomplete list of replies.
1032 Affected file silcd/command.c.
1034 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1036 * Added silc_client_command[s]_[un]register functions now to
1037 dynamically register the commands in client library. Removed
1038 the static table of commands. This allows the client library
1039 to call commands without causing the application to know about
1040 what commands library has called.
1042 Removed the INFO command reply kludge to detect when the command
1043 was called by library. Now library use its own command reply
1044 function for INFO command.
1046 Added function silc_client_command_call to call a command.
1047 Application can use it to call command, not access the structure
1050 Now all commands that are sent by the client library (not
1051 explicitly sent by application) use own command reply functions.
1053 Affected files around lib/silcclient/ and in
1054 irssi/src/silc/core/.
1056 * Fixed the WHOIS command reply sending to chech better valid
1057 clients. It was possible to send incomplete list of replies.
1059 Fixed the WHOIS and IDENTIFY to send the request to router
1060 if normal server did not do it and did not find any results.
1062 Affected file silcd/command.c.
1064 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1066 * Moved the internal data from SilcClient context into its
1067 own file, not accesible to application. Affected files
1068 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1069 and other files in client library.
1071 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1073 * Added doc/examples installation target in Makefile.am.pre.
1076 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1078 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1079 commands the found client entry will be removed from the
1080 cache, after notifying application about the error. Affected
1081 file lib/silcclient/command_reply.c.
1083 * Changed the /MSG to check for exact nickname user gave, and
1084 not let `nick' match `nick@host' if it is only one found. Now,
1085 user must type the exact nickname (like nick@host2) even if
1086 there are no more than one same nicks found. This is to avoid
1087 a possibility of sending nickname to wrong nickname since
1088 `nick' could match `nick@host'. Affected file is
1089 irssi/src/core/silc-servers.c.
1091 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1093 * Do not print "you are now server operator" or similar when
1094 giving /away command. Affected files are
1095 irssi/src/silc/core/client_ops.c, silc-servers.h.
1097 * Made the silc_server_command_pending_error_check to send
1098 the same command reply payload it received back to the
1099 original sender of the command. This way all arguments
1100 that was received by the server will be received by the
1101 client too. Affected file silcd/command.c.
1103 * Added the silc_idcache_add to return the created cache entry
1104 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1106 * Add global clients to expire if they are not on any channel.
1107 This is because normal server will never know if they signoff
1108 if they are not on any channel. The cache expiry will take
1109 case of these entries. This is done by normal servers only.
1110 The affected files are silcd/command_reply.c,
1111 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1113 * If server receives invalid ID notification for WHOIS or
1114 IDENTIFY and the ID exists in the lists, it is removed.
1115 Affected file silcd/command_reply.c.
1117 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1118 in client then client entry that it matches is searched and
1119 the nickname is printed on the screen for user. Affected
1120 file irssi/src/silc/core/client_ops.c.
1122 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1124 * Use cache entry expire time in the LIST command reply to
1125 purge old entries from the cache after the LIST command
1126 reply has been received. This way we don't have non-existent
1127 entries in the cache for too long. Affected file is
1128 silcd/command_reply.c.
1130 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1132 * If we are normal server, and we've not resolved client info
1133 in WHOIS or IDENTIFY from router, and it is global client,
1134 we'll check whether it is on some channel. If it is not
1135 then we cannot be sure about its validity and will resolve it
1136 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1137 file silcd/command.c.
1139 * Search channel by name (if possible) rather than by ID
1140 in IDENTIFY command's command reply. Affected file is
1141 silcd/command_reply.c.
1143 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1145 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1146 Updated specs and implemented it. Affected file silcd/command.c,
1147 silcd/packet_send.c and silcd/packet_receive.c.
1149 * Implemented the <founder auth> payload handling in the JOIN
1150 command. If provided all conditions for channel joining
1151 except requirement to provide correct passphrase can be
1152 overrided by the channel founder. Updated the protocol specs.
1153 Affected file silcd/command.c.
1155 Added support for founder auth in JOIN command in client
1156 library. Fixed the parsing of the JOIN command now to support
1157 all options as they should be. The affected file is
1158 lib/silcclient/command.c.
1160 * Optimized the WHOIS and IDENTIFY commands to send the request
1161 to router only if it includes nicknames or other names. If
1162 they include only IDs then check the local cache first before
1163 routing. Affected file is silcd/command.c.
1165 * Added channels topic announcements. Affected file is
1166 silcd/packet_receive.c and silcd/server.c.
1168 * Fixed the silc_server_send_notify_topic_set to really destine
1169 the packet to channel. Affected file silcd/packet_send.c.
1171 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1172 library. Affected file lib/silcclient/client_notify.c.
1174 * Added UMODE announcements. Affected file silcd/server.c.
1176 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1178 * Memory leak fixes in:
1180 lib/silcutil/silcsockconn.c
1181 lib/silcske/silcske.c
1182 lib/silcske/groups.c
1184 lib/silccrypt/silcpkcs.c
1185 lib/silccore/silccommand.c
1186 lib/silccore/silcidcache.c
1191 * ROBOdoc documented the lib/silcske/groups.h file and a
1192 bit changed the interface for better.
1194 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1196 * Update the client entry context in the ID cache after
1197 nick change. Affected file lib/silcclient/command.c.
1198 Fixes the CUMODE command when regaining founder privileges,
1199 and a little WHOIS problem.
1201 * Fixed silc_net_gethostbyname to correctly call the
1202 inet_ntop. Affected file lib/silcutil/silcnet.c.
1204 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1206 * Added IPv6 support checking to the configure.in.pre, added
1207 also --enable-ipv6 option to override the check. Affected
1208 file configure.in.pre.
1210 * The silc_thread_create now calls the start function
1211 directly if threads support is not compiled in. Removes
1212 ugly #ifdef's from generic code. Affected files are
1213 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1215 * Added silc_net_gethostby[name/addr]_async to asynchronously
1216 resolve. Affected files are lib/silcutil/silcnet.[ch].
1218 * Added support for rendering IPv6 based server, client and
1219 channel IDs. Affected file lib/silcutil/silcutil.c.
1221 * Added support for creating IPv6 based server IDs. Affected
1222 file is silcd/serverid.c.
1224 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1226 * Added silc_net_gethostby[addr/name] into the
1227 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1228 routines. Added silc_net_is_ip[4/6]. Affected file is
1229 lib/silcutil/unix/silcunixnet.c. All routines that take
1230 address as argument now supports both IPv4 and IPv6 addresses.
1232 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1234 * Fixed LIST command reply sending in server. Affected file
1237 * Server now sends the kicker's client ID in the KICK notify
1238 to the kicked client. Affected file silcd/command.c.
1240 * The client library now parses the kickers client ID and
1241 UI displays it. Affected files lib/silcclient/client_notify.c
1242 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1244 * Made all payload parsing function prototypes consistent.
1245 They all take now const unsigned char * and uint32 pair as
1246 the payload data instead of SilcBuffer. Changes all around
1247 the source tree. Other unsigned char* -> const unsigned char*
1248 changes around the tree as well.
1250 * Optimized SFTP client and server packet sending not to
1251 allocate new buffer for each packet but to recycle the
1252 first allocated buffer. Affected files are
1253 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1255 * Optimized the SFTP client to use SilcList instead of
1256 SilcDList for requests, because it is faster. Affected file
1257 is lib/silcsftp/sftp_client.c.
1259 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1260 into lib/silccore/silcid.[ch].
1262 Renamed silcpayload.[ch] into silcargument.[ch].
1264 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * If client entry is deleted with active key agreement
1267 session, abort the session.
1269 The silc_client_abort_key_agreement now calls the completion
1270 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1272 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1275 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Don't use __restrict in older GCC's. Affected file is
1278 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1280 * silc_net_localhost now attempts to reverse lookup the
1281 IP/hostname. Affected file lib/silcutil/silcnet.c.
1283 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1284 command. It can be used to gain founder privileges at
1285 the same time when joining the channel.
1287 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1288 kicker's client ID as well. Updated protocol specs.
1290 Defined that the server must send SILC_COMMAND_IDENTIFY
1291 command reply with error status to client who sent
1292 private message with invalid client ID.
1294 Updated the protocol specification.
1296 * Added silc_server_send_command_reply to send any
1297 command reply. Affected file silcd/packet_send.[ch].
1299 * Added silc_id_payload_encode_data to encode ID payload
1300 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1302 * The server now send IDENTIFY command reply with error
1303 status if client ID in private message is invalid. Affected
1304 file silcd/packet_receive.c.
1306 * Save the server key file with server's IP address in
1307 the filename instead of hostname. The affected file is
1308 irssi/src/silc/core/client_ops.c.
1310 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1312 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1315 * Added libtool support for compiling shared objects in
1316 lib/silcsim. Affected file configure.in.pre and
1317 lib/silcsim/Makefile.am. Original patch by cras.
1319 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1321 * Pid file configuration, and server's config file fixes
1322 patch by toma. Updated CREDITS file.
1324 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1326 * Fixed silc_client_channel_message to not try to decrypt
1327 the message twice if it resolved the destination client
1328 information. This could cause of dropping one channel
1329 message. Affected file lib/silcclient/client_channel.c.
1331 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1333 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1334 lib/silcclient/client.c. This function is used when the SILC
1335 Client is run under some other scheduler, or event loop or
1336 main loop. On GUI applications, for example this may be
1337 desired to used to run the client under the GUI application's
1338 main loop. Typically the GUI application would register an
1339 idle task that calls this function multiple times in a second
1340 to quickly process the SILC specific data.
1342 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1344 * Fixed silc_server_drop() for dropping the supplementary
1345 groups as well, this could cause a security hole on some
1348 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1353 * Write PID file after dropping privileges. Added -F option
1354 to run server on foreground. A patch by debolaz.
1355 Affected files silcd/server.c, silcd/silcd.c.
1357 * Fixed MOTD to return the MOTD file server name. Affected
1358 file silcd/command.c.
1360 * Added INFO command reply handling to the Irssi SILC Client.
1361 Affected file irssi/src/silc/core/client_ops.c.
1363 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1365 * Fixed the silc_idcache_list_* routines to really support
1366 the dynamic list. Fixes a crash. Affected file is
1367 lib/silccore/silcidcache.c.
1369 * Fixed the LIST command reply to really call LIST command's
1370 pending callbacks. Affected file silcd/command_reply.c.
1372 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1374 * Update conn->local_entry->nickname after giving NICK
1375 command. Affected file lib/silcclient/command.c.
1377 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1379 * Added the [pid] option to the silcd configuration file
1381 Affected files: serverconfig.[ch] and silcd.c
1383 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1385 * Save fingerprint in WHOIS command reply in server.
1386 Affected file silcd/command_reply.c.
1388 * Fixed NICK commands pending callback registration.
1389 Affected file lib/silcclient/command.c.
1391 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * Use ++server->cmd_ident when sending commands in server,
1394 instead of random number. Affected file silcd/command.c.
1396 * Fixed GETKEY command reply to call actually GETKEY pending
1397 command callbacks. Affected file silcd/command_reply.c.
1399 * A bit stricter check for nicknames. Check for same nickname
1400 in NICK command also. Affected file silcd/command.c.
1402 * Do not call INFO command everytime client ID changes, only
1403 during first connecting. Affected file lib/silcclient/client.c.
1405 * Set the new nickname only after successful command reply for
1406 NICK command is returned by server. Affected file
1407 lib/silcclient/command.c.
1409 * Remove nicknames from nicklist during server_signoff notify.
1410 Should fix /NAMES bit more. The affected file is
1411 irssi/src/silc/core/silc-channels.c.
1413 * Added `fingerprint' field to the SilcIDListData in the
1414 silcd/idlist.h to hold the fingerprint of the client's
1417 Send the fingerprint of the client's public key in WHOIS
1420 Affected files silcd/command.c, and silcd/idlist.[ch].
1422 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1423 create fingerprint from given data.
1425 * Show the fingerprint of the client's public key in WHOIS.
1426 Affected files irssi/src/module-formats.[ch] and
1427 irssi/src/silc/core/client_ops.c.
1429 * Format the multiple same nicknames also during JOIN and
1430 NICK_CHANGE notifys. Affected file is
1431 lib/silcclient/client_notify.c.
1433 * Do not print error on screen for invalid private message
1434 payload since it can come if someone is sending private
1435 messages with wrong key. Affected file
1436 lib/silccore/silcprivate.c.
1438 * Fixed multiple concurrent /PING crash. Affected file
1439 lib/silcclient/command.c.
1441 * Changed the wrong ID encoding. All IP addresses must be
1442 in MSB first order in encoded format. They were encoded
1443 wrong and was in LSB format. Affected files are
1444 silcd/serverid.c, lib/silcutil/silcutil.c.
1446 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1448 * Call the `connect' client operation through the scheduler
1449 in case of error. Affected file lib/silcclient/client.c.
1451 * Call the `failure' client operation even if the error
1452 occurred locally during a protocol. Affected file is
1453 lib/silcclient/protocol.c.
1455 * Added support of sending LIST command to router from normal
1456 server. This way normal server can get list of all channels
1457 in the network too. Fixed the channel list sending in the
1458 server too. Affected files are silcd/command.c, and
1459 silcd/command_reply.[ch].
1461 * Added silc_server_update_channels_by_server and
1462 silc_server_remove_channels_by_server. They are used during
1463 disconnection of primary router and in backup router protocol.
1464 Affected file silcd/server_util.[ch], silcd/server.c and
1465 silcd/server_backup.c.
1467 * Fixed channel adding to global list in IDENTIFY command
1468 reply in server. Affected file silcd/command_reply.c.
1470 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * If the incoming packet type is REKEY or REKEY_DONE process
1473 that packet always synchronously. Fixes yet another MAC
1474 failed error on slow (dialup) connections. Affected file
1475 lib/silcclient/client.c and silcd/server.c.
1477 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * Call check_version SKE callback for initiator too. Affected
1480 file lib/silcske/silcske.c.
1482 * Implemented fix for security hole found in the SKE that was
1483 fixed in the specification few days back; the initiator's
1484 public key is now added to the HASH value computation.
1485 Added backwards support for the old way of doing it too, for
1486 old clients and old servers. Affected file is
1487 lib/silcske/silcske.c.
1489 * Enabled mutual authentication by default in SKE. If initiator
1490 is not providing mutual authentication the responder will
1491 force it. This will provide the proof of posession of the
1492 private key for responder. The affected files are
1493 lib/silcclient/protocol.c and silcd/protocol.c.
1495 * Do not cache anymore the server's public key during SKE.
1496 We do mutual authentication so the proof of posession of
1497 private key is done, and if the server is authenticated in
1498 conn auth protocol with public key we must have the public
1499 key already. Affected file silcd/protocol.c.
1501 * Added new global debug variable: silc_debug_hexdump. If
1502 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1503 file lib/silcutil/silclog.[ch].
1505 * Fixed compilation warning due to char * -> const char *.
1506 Affected files lib/silcutil/silcnet.h, and
1507 lib/silccore/silcauth.[ch].
1509 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1511 * Fixed CMODE command when new channel key was created. If
1512 the creation failed the old key was removed. Next time giving
1513 same command would crash the server since the old key was
1514 freed already. Affected file silcd/command.c.
1516 * Fixed the silc_server_announce_get_channels to not crash
1517 on reconnect. Affected file silcd/server.c.
1519 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1521 * Added silc_log_set_debug_string function to set a regex
1522 string to match for debug output. Only the function names,
1523 or filenames matching the given debug string is actually
1524 printed. This way it is possible to filter out those debug
1525 strings that user is not interested in.
1527 Fixed a bug in silc_string_regexify.
1529 Affected files lib/silcutil/silclog.[ch], and
1530 lib/silcutil/unix/silcunixutil.c.
1532 * Changed the -d options in both server and Irssi SILC client
1533 to take the debug string as argument. Affected files
1534 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1536 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Added silc_hash_babbleprint to create a Bubble Babble
1539 Encoded fingerprint. The encoding is developed by Antti
1540 Huima (draft-huima-babble-01.txt), and it creates human
1541 readable strings out of binary data. Affected file
1542 lib/silccrypt/silchash.[ch].
1544 * Print the babble print now in addition of fingerprint as well
1545 in Irssi SILC client. Affected files are
1546 irssi/src/fe-common/silc/module-formats.[ch],
1547 irssi/src/fe-common/silc/core/client_ops.c.
1549 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Fixed a security problem found in SKE. The initiator's
1552 public key too is now added to the HASH hash value creation
1553 which is signed by the responder to create the SIGN value.
1554 This will prevent anyone in the middle to lie to the responder
1555 about the initiator's public key. If this is done now, the
1556 man in the middle will get caught. Updated the protocol
1559 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1561 * Better installation directory handling. Configure module
1562 paths and other paths automatically to example_silc* files
1563 in doc/. A patch by toma.
1565 * Fixed compiler warning from MPI library, and from SILC RNG.
1568 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1569 It can be configured with ./configure. A patch by toma.
1571 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Find correct make to use in prepare-clean. A patch by
1574 toma. Affected file prepare-clean.
1576 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1578 * Added irssi variables use_auto_addr, auto_bind_ip,
1579 auto_bind_port and auto_public_ip.
1581 * Changed the interface for silc_client_send_key_agreement
1582 in lib/silcclient/silcapi.h
1586 irssi/src/silc/core/silc-core.c
1588 lib/silcclient/silcapi.h
1589 irssi/src/silc/core/silc-channels.c
1590 lib/silcclient/client_keyagr.c
1593 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Added silc_pkcs_public_key_compare to compare two
1596 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1598 * Check that the client who set the founder mode on the
1599 channel is the same client that is giving the founder
1600 mode to itself. It is done by comparing the saved public
1601 key (it is saved even in the authentication is passphrase).
1602 Affected file silcd/command.c.
1604 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1606 * Do not process packet for disconnected socket connection.
1607 Affected file lib/silccore/silcpacket.c.
1609 * Process the DISCONNECT packet through scheduler in the
1610 client library. Affected file lib/silcclient/client.c.
1612 * Fixed the silc_client_packet_parse to not to increase
1613 the packet sequence number if the conn->sock and the
1614 current socket connection is not same. This can happen
1615 for example during key agreement when the conn includes
1616 multiple socket connections (listeners). Affected file
1617 lib/silcclient/client.c.
1619 * The sender of the file transfer request now provides also
1620 the pointer (listener) for the key exchange protocol. If
1621 the listener cannot be created then it sends empty key
1622 agreement and lets the receiver provide the listener.
1624 Added `local_ip' and `local_port' arguments to the
1625 silc_client_file_send. If they are provided they are used,
1626 if not then it will attempt to find local IP address, if
1627 not found or bind fails then the remote client will provide
1630 Affected files are lib/silcclient/client_ftp.c and
1631 lib/silcclient/silcapi.h.

1706 preserve the WHOWAS info for the client. Affected file
1707 silcd/server_util.c.
1709 * Fixed SERVER_SIGNOFF notify handling in the server. The
1710 server is now able to process incoming SERVER_SIGNOFF notify
1711 for a server that it doesn't even know about. It will remove
1712 the clients provided in the notify. Affected file
1713 silcd/packet_receive.c.
1715 * Check for partial packet in data queue after every packet that
1716 was found from the queue. Return and wait for more data if
1717 there is partial data in queue. Affected file is

1739 * Added silc_rng_global_get_byte_fast to get not-so-secure
1740 random data as fast as possible. Random data is read from
1741 /dev/urandom if available and from the SILC RNG if not
1742 available. It is used in padding generation. Affected file
1743 lib/silccrypt/silcrng.[ch].
1745 * All packets in client library are now processed synchronously.
1746 Optimized packet processing a lot. Affected file
1747 lib/silcclient/client.c.

1758 * Assure that silc_client_notify_by_server_resolve does not
1759 resolve the client information multiple times. If it cannot
1760 be found by the first it cannot be found at all. Affected
1761 file lib/silcclient/client_notify.c.
1763 * Fixed WHOWAS command reply calling. Affected file
1764 lib/silcclient/command_reply.c.
1766 * Removed all references to silc_idlist_get_client from the
1767 Irssi SILC client since that call is internal call used by
1768 the library. The Irssi SILC client will use now client
1769 retrieval functions found in silcapi.h.
1771 * Fixed a bug in resolving nickname info before sending
1772 private message. It used freed memory. Affected file
1773 irssi/src/silc/core/silc-servers.c.
1775 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1777 * Assure my_channels statistics cannot go negative in server.
1778 Affected files silcd/server.c, silcd/server_util.c.

1794 * Added silc_net_localip to return local host's IP address.
1795 Affected file lib/silcutil/silcnet.[ch].
1797 * If key exchange or rekey protocol is active for a connection
1798 parse all packets syncronously since there might be packets
1799 in packet queue that we are not able to process without first
1800 processing packets before them. Affected file silcd/server,
1801 lib/silcclient/client.c.
1803 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1804 whether library should continue processing the packet.
1805 Affected file lib/silccore/silcpacket.h.

1851 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1852 is incomplete and is being resolved, it won't be resolved
1855 Make sure also that USERS command reply does not resolve
1856 twice information. Affected file is
1857 lib/silcclient/command_reply.c.
1859 Make sure that silc_client_get_clients_by_list does not
1860 resolve twice same information.
1862 * Check for valid client->id in the silc_server_free_client_data.
1863 Affected file silcd/server.c.
1865 * Fixed /GETKEY nick@server not to crash if the server entry
1866 is not found. Affected file lib/silcclient/command.c.
1868 * Fixed the silc_server_check_cmode_rights to check the

1876 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1878 * Call the silc_server_udpate_servers_by_server in the
1879 primary router that comes back online in the backup resuming
1880 protocol. Otherwise it routes packets wrong. Affected file
1881 silcd/server_util.[ch], silcd/server_backup.c.
1883 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1885 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1886 lib/silcutil/silcbuffmt.[ch].
1888 * Redefined the SILC packet header to include the padding
1889 length. Affected file lib/silccore/silcpacket.[ch].
1891 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1892 length for maximum padding up to 128 bytes). Affected
1893 file lib/silccore/silcpacket.h.
1895 * Removed all backwards support for old 0.5.x MAC thingies.
1896 The SILC packet header change makes it impossible to be
1897 backwards compatible.
1899 * Send the ENDING packet with timeout in the backup resuming
1900 protocol. This is to assure that all routers has connected
1901 to the primary router. Affected file silcd/server_backup.c.
1903 * Changed the RNG to take the first IV from random data. It
1904 used to take it from zero actually. Changed the RNG also
1905 to use /dev/urandom during session. /dev/random is used
1906 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1908 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Changed the SILC packet header to have the first two bytes
1911 (the packet length) encrypted. Affected files aroung the
1912 code tree, lib/silccore/silcpacket.[ch]. Removed the
1913 SilcPacketCheckDecrypt callback. It is not needed anymore
1914 since the silc_packet_receive_process will determine now
1915 whether the packet is normal or special.
1917 * Implemented the unidirectional MAC keys. Affected files
1918 lib/silcske/silcske.c, silcd/protocol.c and
1919 lib/silcclient/protocol.c.
1921 * Implemented the packet sequence number to the MAC computation.
1922 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1923 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1924 lib/silcclient/protocol.c.
1926 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1928 * Allow backup router to announce servers. All servers
1929 announced by backup router are added to the global list
1930 automatically. Update hte server's socket to our primary
1931 router also when backup router announces a server.
1932 Affected file silcd/packet_receive.c.
1934 * Do not update the client->router in the function
1935 silc_server_udpate_clients_by_server if the client is on
1936 global list. We might fail to find any specific server
1937 for locally connected clients and local cell clients. They
1938 should still use the `from' and not `to' as client->router.
1939 This fixes backup router resuming protocol. Affected file
1940 silcd/server_util.c.
1942 * Decrease channel statistics count only if the channel
1943 deletion worked. Affected files are silcd/server.c and
1944 silcd/server_util.c.
1946 * Added silc_server_update_servers_by_server to update origin
1947 of all server entries. Used during backup router protocol.
1948 Affected files silcd/server_util.[ch], silcd/server.c. and
1949 silcd/backup_router.c.
1951 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1952 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1953 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1954 lib/silccrypt/silchmac.c.
1956 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1958 * Assure that router cannot reroute the same channel message
1959 to the sender. Affected file silcd/packet_receive.c.
1961 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1963 * Made better checks that the channel message is not sent
1964 to the router it came from. Affected file is
1965 silcd/packet_send.c. Fixed memory leak too.
1967 * Announce informations for incoming router connection, but
1968 only after checking if it is replaced by backup router.
1969 Affected file silcd/packet_receive.c.
1971 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Fixed the backup resuming protocol to work in multiple
1974 router environment. Affected file silcd/server_backup.c.
1976 * Route packet only to one router in the function
1977 silc_server_packet_send_to_channel. Affected file is
1978 silcd/packet_send.c.
1980 * Fixed silc_server_send_notify_dest to set the broadcast
1981 flag. Fixed the silc_server_send_notify_topic to actually
1982 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1983 Affected file silcd/packet_send.c.
1985 * Changed the SFTP Filesystem interface. Changed the
1986 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1987 the filesystem operation function. The SilcSFTPFilesystem
1988 is now a context that is allocated by all filesystem allocation
1989 functions and it already includes the operations structure
1990 and filesystem specific context. It is given as argument
1991 now to the silc_sftp_server_start. This made the interface
1992 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1993 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1995 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Changed the backup router adding and getting interfaces
1998 in the server. The router that will be replaced by the
1999 specified backup router is now sent as argument. Affected
2000 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2003 * Added silc_net_addr2bin_ne to return the binary form of
2004 the IP address in network byte order. Affected files
2005 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2007 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * Check for existing server ID in silc_server_new_server
2010 and in silc_server_connect_to_router_final and remove the
2011 old entry if it exists. Affected file silcd/packet_receive.c,
2014 * Send the channel message always to only one router, either
2015 in upstream or downstream. Affected file is
2016 silcd/packet_send.c.
2018 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * Wrote the definition of the backup resuming protocol to the
2021 protocol specification.
2023 * Removed one redundant channel key generation from normal
2024 server during joining procedure. Removed one redundant
2025 channel key sending from server to router during joining
2026 procedure. Affected file silcd/command.c.
2028 * Made minor bugfixes to the backup router resuming protocol.
2029 Affected file silcd/server_backup.c, server.c.
2031 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Added --disable-asm configuration option. Affected files
2034 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2037 * Implemented the backup resuming protocol that is used to
2038 resume the primary router position in the cell after the
2039 primary router comes back online. Affected files
2040 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2041 and silcd/server_util.[ch].
2043 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Sleep two (2) seconds after sending QUIT command to server.
2046 Affected file lib/silcclient/command.c.
2048 * Assure that if outgoing data buffer is pending do not force
2049 send any data. Affected file silcd/packet_send.c.
2051 * Assure that if outgoing data buffer is pending do not force
2052 send any data. Affected file lib/silcclient/client.c.
2054 * Implemented the backup router support when the primary router
2055 goes down. The servers and routers can now use the backup
2056 router as new primary router without loosing connectivity.
2058 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2061 in the server to indicate disabled entry. All data read
2062 from the connection will be ignored and no data is sent
2063 for entry that is disabled. Affected files are
2064 silcd/idlist.h, silcd/server.c.
2066 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2068 * Created SFTP client and server test programs in the
2069 lib/silcsftp/tests directory.
2071 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * Implemented memory filesystem (virtual filesystem) for
2074 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2077 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Implemented the SFTP (SSH File Transfer Protocol) to the
2080 lib/silcsftp. It includes SFTP client and SFTP server
2083 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2085 * Moved lib/silccore/silcprotocol.[ch] to the
2086 lib/silcutil library.
2088 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2089 take variable argument list pointer as argument. Affected
2090 file lib/silcutil/silcbuffmt.[ch].
2092 * Added silc_buffer_set function that is used to set data
2093 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2094 Affected file lib/silcutil/silcbuffer.h.
2096 * Changed various routines in the core library to use the new
2097 silc_buffer_set instead of allocating new buffer only for
2100 * Added 64-bit value formatting and unformatting support to the
2101 silc_buffer_[un]format routines. Affected file is
2102 lib/silcutil/silcbuffmt.[ch].
2104 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2105 to includes/bitmove.h.
2107 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Fixed channel user mode saving in client library. Affected
2110 file lib/silcclient/command[_reply].c.
2112 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * Defined the file transfer to the SILC Protocol. Added
2115 new packet type SILC_PACKET_FTP and defined File Transfer
2116 Payload. The mandatory file transfer protocol is SFTP
2117 (SSH File Transfer Protocol). Affected file in addition
2118 of the internet draft is lib/silccore/silcpacket.h.
2120 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2121 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2122 is used as part of backup router protocol when the primary
2123 router of the cell is back online and wishes to resume
2124 the position as primary router.
2126 * Redefined the MAC generation keys in the protocol. The
2127 same key is not used anymore in both direction. Both
2128 direction will now use different keys for sending and
2129 receiving. This fixes a potential security flaw. This
2130 change causes incompatibilities in the protocol.
2132 * Redefined also the MAC computation from the packet.
2133 An packet sequence number is now added to the MAC
2134 computation. This prevents possible replay attacks against
2135 the protocol. This change too causes incompatibilities
2138 Added `sequence' field to the SilcPacketContext to hold
2139 the current sequence number for the packet.
2141 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Added `created' field to the SilcIDListData in the file
2144 silcd/idlist.h to indicate the time when the entry was
2147 * Added `created' field to the SilcChannelEntry too. Affected
2148 file silcd/idlist.h.
2150 * Added `creation_time' aguments to all the announcement functions
2151 in the server. If it is provided then only the entries that
2152 was created after the provided time frame are actually
2153 announced. Affected file silcd/server.[ch].
2155 * The protocol says that the Channel ID's IP address must be
2156 based on the router's IP address. Added check for this in
2157 the silc_server_new_channel when processing incoming New Channel
2158 Payload. Affected file silcd/packet_receive.c.
2160 * Print out the correct version with --version in SILC client.
2161 Affected file irssi/src/silc/core/silc-core.c.
2163 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2165 * Fixed WHOWAS command to check for completnes of the client
2166 entry always, not just when the command is coming from client.
2167 Affected file silcd/command.c.
2169 * Added new function silc_server_packet_queue_purge to purge the
2170 outgoing data queue to the network. After the function returns
2171 it is guaranteed that the outgoing packet queue is empty.
2172 Affected file silcd/packet_send.[ch].
2174 * Purge the outgoing packet queue in the rekey protocol's final
2175 callback to assure that all rekey packets go to the network
2176 before quitting the protocol. Affected file silcd/server.c.
2178 * Added silc_client_packet_queue_parse as similar function as
2179 in server to the client library. The affected file is
2180 lib/silcclient/client.c.
2182 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Splitted silcd/server.c and created silcd/server_util.[ch]
2185 for utility functions.
2187 * Added new socket flag SILC_SF_DISABLED to indicate that the
2188 connection is open but nothing can be sent to or received from
2189 the connection. Affected file lib/silcutil/silsockconn.[ch].
2190 The checking for disabled socket is checked in the low level
2191 silc_socket_write and silc_socket_read functions.
2193 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Allow only nicknames and channel names that fits into the
2196 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2198 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2200 * When processing JOIN command reply in server check that if
2201 the channel exists in our global list we'll move it the local
2202 list. Affected file silcd/command_reply.c.
2204 * Fixed the check whether client is joined on the channel already
2205 in JOIN command. Affected file lib/silcclient/command.c.
2207 * Fixed the JOIN command reply to check whether the channel
2208 already exists. Affected file lib/silcclient/command_reply.c.
2210 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2212 * Added silc_ske_status_string to map the SKE error numbers
2213 to readable strings. The affected files are
2214 lib/silcske/silcske[_status].[ch].
2216 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2218 * Do not show the private channels on the WHOIS channel list
2219 as it is not allowed by the protocol. The affected file is
2222 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2224 * Assure that the packet length digged from the actual packet
2225 is something sensible in the silc_packet_decrypt_rest_special
2226 in lib/silccrypt/silcpacket.c.
2228 * Free and NULL the allocated pointer in silc_hmac_alloc if
2229 the HMAC allocation fails. The affected file is
2230 lib/silccrypt/silchmac.c.
2232 * Print the selected security properties to the log files in
2233 the server. Affected file silcd/protocol.c.
2235 * Add SKE's reference counter even if calling the completion
2236 callback manually. Otherwise it goes negative, although it
2237 does not cause any problems. The affected file is
2238 lib/silcske/silcske.c.
2240 * Remove the client entry with short timeout after giving the
2241 KILL command. Affected file lib/silcclient/command.c.
2243 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2244 case all found clients are already disconnected (WHOWAS would
2245 found them) in the server. Affected file silcd/command.c.
2247 * Update the last_receive (time of last data received) to be
2248 updated only when received private or channel message so that
2249 the idle time showed in WHOIS makes more sense.
2251 * Added boolean field `valid' in to the SilcClientEntry in the
2252 client library to indicate whether the entry is valid or not.
2253 This fixes the nickname change bug on channel when changing
2254 the nickname to be same than the old (like nick to Nick) the
2255 nickname formatter doesn't set the new nick anymore to Nick@host.
2256 Affected file lib/silcclient/idlist.[ch].
2258 * Now actually fixed the nickname changing on disconnection.
2259 Added new function silc_change_nick to the Irssi SILC Client.
2260 Affected file irssi/src/silc/core/client_ops.c,
2261 irssi/src/silc/core/silc-nicklist.[ch].
2263 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2265 * Check that the public key exists in the GETKEY command before
2266 trying to encode it. Affected file silcd/command.c.
2268 * Print some notifications on received public keys with GETKEY
2269 command in the Irssi SILC Client. Affected files are
2270 irssi/src/fe-common/silc/module-formats.[ch],
2271 irssi/src/silc/core/client_ops.c.
2273 * Use IDENTIFY command to resolve the server information in the
2274 GETKEY command instead of INFO command. Affected file
2275 lib/silcclient/command.c.
2277 * All command reply functions in the client library now calls
2278 the pending command reply callbacks even if an error has
2279 occurred. The server has done this a long time and now it was
2280 time to move the client library to this as well. Now all
2281 errors can be delivered back to the pending command reply
2282 callbacks if necessary. Affected files are
2283 lib/silcclient/command[_reply].[ch].
2285 * Change the nickname on disconnection back to the username
2286 because in reconnect the server will enforce it to it anyway.
2287 Affected file irssi/src/silc/core/silc-servers.c.
2289 * Fixed a config file parsing bug in the Irssi SILC client.
2290 Affected file irssi/src/silc/core/clientconfig.c.
2292 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * When printing the channel mode on JOIN, verify that the
2295 channel key and channel's HMAC are valid. Affected file
2296 irssi/src/silc/core/client_ops.c.
2298 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2300 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2301 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2302 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2304 * Removed channel key rekey task deleting from the function
2305 silc_server_save_channel_key. Affected file silcd/server.c.
2306 Added explicit timeout task context instead that is used to
2307 delete the task if we are registering a new task before the
2308 new task has elapsed.
2310 * When channel key rekey occurs the client library now saves
2311 the old channel key for a short period of time (10 seconds) and
2312 is able to use it in case some is still sending channel
2313 messages encrypted with the old key after the rekey. Affected
2314 file lib/silcclient/[idlist.h|client_channel.c].
2316 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2318 * Added check to the silc_server_new_id_real to not accept
2319 new ID if it is the sender's own ID. Affected file is
2320 silcd/packet_receive.c.
2322 * Assure that we do not announce ourself or the one we've
2323 sending our announcements when we're router and are announcing
2324 servers to our primary router. Affected file silcd/server.c.
2326 * Fixed silc_server_command_identify_check_client to assemble
2327 correct WHOIS packet. It send corrupted WHOIS packet and
2328 caused problem with router to router connections. Affected
2329 file silcd/command.c.
2331 Fixed also silc_server_command_whois_check the same way
2332 as for the IDENTIFY command.
2334 * Added new SilcIDListStatus to the server in the SilcIDListData
2335 structure. The status now includes the current status of
2336 the entry (like registered, resolved etc.). Affected file
2337 silcd/idlist.[ch]. Defined a bunch of different status types
2338 as well. This replaced the old boolean registered field as well.
2340 Added resolve_cmd_ident field to the SilcClientEntry structure
2341 too so that if the entry is for example being resolved so
2342 another command may attach to the same pending command reply
2343 without requiring to resolve the same entry again. This concept
2344 should optimize the WHOIS and the IDENTIFY resolving under
2345 heavy load by taking away unnecessary resolving for entries
2346 that are being resolved already.
2348 Added support for adding multiple pending commands for one
2349 command idenfier. Affected file silcd/command[_reply].[ch].
2351 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2352 before deleting the data. Otherwise the hash table will have
2353 freed data in comparison functions. Affected file is
2354 silcd/command_reply.c.
2356 * Fixed silc_idlist_replace_client_id to add the new entry to
2357 the cache with NULL nickname. Otherwise there will be invalid
2358 memory as the nickname after the nickname is freed. Affected
2359 file silcd/packet_receive.c.
2361 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2362 saved into wrong slots because the previous number of entries
2363 was not taken into account. Affected file silcd/idlist.c.
2364 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2366 * If we are router and we receive JOIN notify to a channel that
2367 does not have any users then notified client is marked as the
2368 channel founder, as it is it. The affected file is
2369 silcd/packet_receive.c
2371 * Added to the extended hash table API's table_del_*ext functions
2372 the destructor as argument too, so that the caller can decide
2373 which destructor to use or whether to use destructor at all.
2374 Affected file lib/silcutil/silchashtable.[ch].
2376 * Fixed ID Cache purging. It actually deleted the entries from
2377 the hash table after the data was freed. The hash table ended
2378 up comparing freed memory. The affected file is
2379 lib/silccore/silcidcache.c.
2381 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2383 * Fixed Irssi SILC client's KILL command's HELP syntax.
2385 * The USERS command now resolves the detailed user information
2386 if the userinfo field is missing. Affected file is
2387 lib/silcclient/command_reply.c.
2389 * Do not print error in silc_file_read if the read file does
2390 not exist. Just silently return NULL. Affected file is
2391 lib/silcutil/silcutil.c.
2393 * Fixed the silc_log_output to not wine about NULL filename
2394 and to not create some bogus " " filename. Affected file is
2395 lib/silcutil/silclog.c.
2397 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Fixed various printing bugs on the user interface in the
2400 Irssi SILC Client. Minor changes that were forgotten from
2403 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Fixed the configure.in.pre and the compilation and distribution
2406 environment to support the new autoconf 2.52. That version is
2407 now required to compile the CVS trunk.
2409 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2412 to generally parse user@fqdn format strings. Affected file
2413 lib/silcutil/silcutil.c.
2415 * Added nickname_format and nickname_force_format fields to the
2416 SilcClientParams structure. The first one defines the format
2417 for the nicknames that the library will enforce if the receives
2418 multiple same nicknames. The second one is boolean value and
2419 can be used to force the library to always enforce the format
2420 to the nicknames regardles whether there are multiple nicknames
2421 or not. This configurable formatting was employed to flexibly
2422 support accessing multiple nicknames from the user interface.
2423 The userinterface can now set the nicknames to what ever format
2424 they prefer. Affected file lib/silcclient/silcapi.h.
2426 Added function silc_client_nickname_format to the file
2427 lib/silcclient/idlist.c. It performs the nickname formatting.
2429 Added new field `hostname´ to the SilcClientEntry context.
2430 It holds the hostname of the client. Affected file is
2431 lib/silcclient/idlist.h.
2433 * Irssi SILC Client sets the nicknames in nick@hostn format.
2434 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2435 irssi/src/silc/core/silc-core.c.
2437 The WHOIS printing now also shows both the real nickname and
2438 the formatted nickname so that user knows how to access the
2439 user if there are multiple same nicknames cached. Affected
2440 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2441 printing formatting too to take the hostname now as a separate
2442 argument. The Affected file is
2443 irssi/src/fe-common/silc/modules-formats.[ch].
2445 * Changed the silc_client_get_clients_local to accept the formatted
2446 nickname as argument. It accepts the real nickname too but the
2447 formatted nickname can be used to find the true entry from
2448 multiple entries. Affected file lib/silcclient/silcapi.h and
2449 lib/silcclient/idlist.c.
2451 * Added nickname_format_parse field to the SilcClientParams.
2452 It is a callback function provided by the application to parse
2453 the nickname out of the formatted nickname string. The library
2454 calls it to get the nickname from the formatted string. Since
2455 the application generally knows better the format of the nickname
2456 string it parses it instead of the library, even though library
2457 encodes the formatted string. If the callback function is not
2458 provided then the library will use the string as is. The
2459 affected file is lib/silcclient/silcapi.h.
2461 * All the nickname strings passed to the client library in
2462 commands are now expected to be formatted nickname strings.
2463 If the command does not support the formatted nickname string
2464 it will assume that the sent string is the actual nickname.
2465 Affected file lib/silcclient/command.c.
2467 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2469 * Added public key authentication support to OPER and SILCOPER
2470 commands in the client library. Affected file is
2471 lib/silcclient/command.c.
2473 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2475 * Changed the get_auth_methdod client operation to be asynchronous.
2476 It can be async if the application resolves the authentication
2477 method from the server during the negotiation. Added new
2478 SilcGetAuthMeth completion callback that the application will
2479 call after resolving the authentication method.
2481 Added function silc_client_request_authentication_method that
2482 the application can use to resolve the authentication method
2483 from the server. Added also SilcConnectionAuthRequest callback
2484 that the library will call after the server has replied. The
2485 application can call this function if it does not know the
2486 current authentication method.
2488 Affected files are lib/silcclient/client.c and
2489 lib/silcclient/silcapi.h.
2491 * The Irssi SILC client now automatically resolves the authentication
2492 method incase any configuration information is not present (and
2493 currently there never is). The affected file is
2494 irssi/src/silc/core/client_ops.c.
2496 * Fixed public key authentication from the client library.
2497 Affected file lib/silcclient/protocol.c. Changed also the
2498 protocol specification about the public key authentication in
2499 the connection authentication protocol. The actual data to be
2500 signed is now computed with a hash function before signing.
2502 * Fixed the public key authentication from the server as well.
2503 Affected file silcd/protocol.c.
2505 * Removed the mlock()'s from the memory allocation routines.
2506 Affected file lib/silcutil/silcmemory.c. The ./configure does
2507 not check anymore for the mlock(). Affected file is
2510 * Fixed USERS command in server to allow the execution of the
2511 command for private and secret channels if the client sending
2512 the command is on the channel. Affected file silcd/command.c.
2514 * Fixed silc_client_get_clients_local to return the clients
2515 count correctly. It could return wrong value. Affected file
2516 lib/silcclient/idlist.c.
2518 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2520 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2521 types. The assembler optimizations seemed not to like 64-bit
2522 data types. The assmebler optimizations thus are now enabled
2523 also for BSD systems as opposed to only enable them for Linux.
2525 * Do not check for threads at all on BSD systems. Affected
2526 file configure.in.pre.
2528 * Removed -n and -h options from the Irssi SILC Client since
2529 they are not used in silc.
2531 * Fixed the prime generation to assure that the first digit
2532 of the generated random number is not zero since our conversion
2533 routines does not like number strings that starts with zero
2534 digit. If zero digit is seen the random number is regenerated.
2535 This caused some corrupted RSA keys when the zero first digit
2536 was met. Affected file lib/silcmath/silcprimegen.c.
2538 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2540 * Fixed WIN32 configuration in the ./configure script.
2541 Fixed to include xti.h on environments that has it.
2542 Patches by Carsten Ilchmann and andrew.
2544 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2546 * Changed the silc_id_create_client_id to be collision
2547 resistant. It is now assured that there cannot be created
2548 two same client ID's. I suspect that some weird bugs in
2549 the server were actually caused by duplicate Client IDs.
2550 Affected file silcd/serverid.[ch]. A router receiving
2551 new ID now also assures and informs the sending server
2552 if the ID caused collision.
2554 * Changed the silc_id_create_channel_id to also assure that
2555 there are no collisions.
2557 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2559 * Statement about ignoring the Mutual Authentication flag when
2560 performing rekey with PFS was a bit misleading. It is ignored
2561 if it was set in the initial negotiation, it cannot be even
2562 set in the rekey. Fixed in the ke-auth draft. Started the
2563 new versions of the protocol drafts in the doc/.
2565 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Fixed a bug in silc_client_command_identify_save when saving
2568 new channel information. The channel name was no duplicated
2569 and caused crash on exit. Affected file is
2570 lib/silcclient/command_reply.c.
2572 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2574 * Fixed the getkey command handling in the server. Send just
2575 empty OK reply to the sender if the key could not be fetched
2576 (but everything else was ok, like the key just was not available).
2577 Changed the public key parameter to optional in the protocol
2578 specs so that empty OK reply can be sent. Affected file
2581 Added a message to Irssi SILC client to tell to user if the
2582 server did not return a public key.
2584 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Fixed a channel key regeneration bug. It registered new
2587 timeout tasks exponentially until all system resources were
2588 used. Affected file silcd/server.c.
2590 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Added the SILC Document generator to the scripts/silcdoc.
2593 It can be used to generate the Toolkit Reference Manual out
2594 of the source tree. Internally it will also use the RoboDoc
2595 generator now imported in util/robodoc.
2597 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * Added couple of return's in rekey protocol if error orccurred
2600 during the protocol. The execution must be terminated.
2601 Affected file silcd/protocol.c. Also, terminate the protocol
2602 always with timeout.
2604 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * The client's Client ID was created initally from the wrong
2607 nickname (it could have been in format nick@host) in the
2608 silc_server_new_client. Affected file silcd/packet_receive.c
2610 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2612 * Added some SILC_LOG_ERROR's to various error conditions
2613 if client could not be added to ID cache. Affected files
2614 silcd/packet_receive.c and silcd/server.c.
2616 * When client's sock->user_data is freed, NULL also the
2617 client->router and client->connection pointers. Added check
2618 for these pointers being NULL to various places around the
2619 code. Affected file silcd/server.c.
2621 * Added client->data.registered == TRUE checks to various
2622 places around the code to assure that unregistered client's
2623 are not handled when it is not allowed. Affected file
2626 * Added `bool registered' fields to all
2627 silc_idlist_[server|client]_get_* routines to indicate whether
2628 the fetched client needs to be registered or not. Affected
2629 file silcd/idlist.[ch].
2631 * Add your own entry as registered to the ID cache in the
2632 server. Affected file server.c.
2634 * Fixed a bug in silc_server_new_server. The SilcServer was
2635 set as the new server's context instead of SilcServerEntry.
2636 This naturally caused some weird bugs.
2638 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2640 * Do not delete the channel rekey task when adding it
2641 for in silc_server_create_channel_key.
2643 * Changed the silc_server_create_channel_key to return
2644 TRUE or FALSE to indicate the success of the channel key
2647 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2649 * Fixed MSVC++ project files and added missing files to
2650 Makefiles under win32/.
2652 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2654 * Do not add TCP_NODELAY flag if the operating system
2655 does not have it defined. Affected files are
2656 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2658 * Fixed buffer overflow from Irssi SILC Client. Affected
2659 file irssi/src/fe-common/core/themes.c.
2661 * Fixed double free in client library in the file
2662 lib/silcclient/client.c when disconnecting from server.
2664 * Applied double free patch from cras to Irssi SILC client.
2665 Affected files irssi/src/core/[modules/expandos].c
2667 * Fixed the disconnection handling to Irssi SILC Client.
2668 The application must call silc_client_close_connection
2669 in ops->connect client operation in case of failure of
2670 the connection. Affected file is
2671 irssi/src/silc/core/client_ops.c.
2673 * Do not set sock->protocol to NULL in the function
2674 silc_client_close_connection after executing the protocol's
2675 final callback since the sock might not be valid anymore.
2676 Affected file lib/silcclient/client.c.
2678 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2680 * Do not enable SILC_THREADS if the linking with libpthread
2681 did not happen. Affected file configure.in.pre.
2683 * Added notion to protocol specification that server must
2684 verify the sent authentication payload with CMODE when
2685 setting the channel founder key. Implemented it to the
2686 server. Affected file silcd/command.c.
2688 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Added _EXTRA_DIST SILC distribution variable to the
2691 distributions file. It is used to conditionally add extra
2692 files or directories to the specific distribution. Affected
2693 files ./prepare, Makefile.am.pre and distributions.
2695 Removed the `_' from the start of the distribution names.
2698 * Added README.WIN32 for instructions to compile the Toolkit
2701 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2703 * Fixed a double free in disconnection in the server. Affected
2704 file is silcd/server.c.
2706 * Fixed the lib/silcske/groups.c to work now also with GMP
2707 MP library. The string conversion did not work when using
2708 specific base and the base is indicated in the string as well.
2710 * Created win32/ directory which now includes MSVC++ specific
2711 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2712 It will appear only in the toolkit distribution
2714 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2716 * Changed the key material distribution function in case when
2717 the hash output is too short. The data is now concatenated
2718 a bit differently than it used to. Made the change to the
2719 SKE protocol specification.
2721 * Added better GMP detection to configure.in.pre. A patch
2724 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2726 * Fixed a minor bug in SKE that might cause some problem on
2727 some platforms. Affected file lib/silcske/silcske.c.
2729 * Added the cookie checking for initiator in the SKE. It checks
2730 that the responder returns the sent cookie unmodified. The
2731 affected file is lib/silcske/silcske.c. Added new SKE
2732 error type INVALID_COOKIE that can be sent during the
2733 negotiation. Fixed some memory leaks as well.
2735 * Added the "invalid cookie" error message to Irssi SILC client's
2738 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2740 * Added `task_max' field to the SilcClientParams to indicate
2741 the maximum tasks the scheduler can handle. If set to zero,
2742 default values are used. Affected file lib/silcclient/silcapi.h.
2744 * Fixed memory leaks in silc_client_close_connection. Affected
2745 file lib/silcclient/client.c.
2747 * Added silc_client_del_client_entry to client library to free
2748 all memory of given client entry. Affected file is
2749 lib/silcclient/idlist.[ch].
2751 * Added new functions silc_client_del_channel and
2752 silc_client_del_server to delete channel and server entries.
2753 Affected file lib/silcclient/[silcapi.h/idlist.c].
2755 * Removed silc_client_del_client_by_id from silcapi.h.
2757 * Fixed the INFO command to return the server's own info
2758 correctly when querying by Server ID. Affected file is
2761 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2763 * Removed the non-blocking settings in WIN32 code in the
2764 silc_sock_[read/write] and added SleepEx instead. Affected
2765 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2766 of input data is now checked with FIONREAD and ioctlsocket.
2768 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Call silc_schedule_task_del_by_context in the
2771 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2772 Affected file lib/silccore/silcprotocol.c.
2774 * Call silc_protocol_cancel for active protocols in the
2775 silc_server_close_connection if the funtion
2776 silc_server_free_sock_user_data has not been called.
2777 Affected file silcd/server.c.
2779 * Generic tasks cannot be deleted using the del_by_fd
2780 task deleting function since generic tasks does not match
2781 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2783 * Added a notion to SILCOPER help file that the SILCOPER works
2784 only on router server, not on normal server.
2786 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * Added for WIN32 support for the new scheduler as well.
2789 Affected file lib/silcutil/win32/silcwin32schedule.c.
2791 * Fixed the SHA1 implementation to work on various platforms.
2793 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2796 API. It is part of the scheduler now. Everything else is
2797 as previously but some functions has changed their names.
2798 Checkout the lib/silcutil/silcschedule.h for the interface.
2799 Updated all applications to use the new interface. Affected
2800 files are lib/silcutil/silcschedule.[ch].
2802 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2804 * Found a bug in the SKE implementation. The HASH value,
2805 specified by the protocol, was not computed correctly. The
2806 public key of the responder was not added to the computation
2807 even though it is mandatory. Affected file lib/silcske/silcske.c.
2808 This unfortunately causes incompatibilities with older
2809 clients and servers.
2811 * Added WIN32 specific network init and uninit functions:
2812 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2813 the Winsock2. Affected file lib/silcutil/silcnet.h and
2814 lib/silcutil/win32/silcwin32net.c.
2816 * Set the socket always to nonblocking mode on WIN32 after
2817 reading data or writing data. Affected file is
2818 lib/silcutil/win32/silcwin32sockconn.c.
2820 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2822 * Fixed various compilation problems under WIN32. Affected
2823 files lib/silcutil/win32/silcwin32thread.c and
2824 lib/silcutil/win32/silcwin32schedule.c.
2826 * Removed all _internal.h #includes from public header
2827 files. Internal headers must never be included from
2830 Removed also the lib/silcske/payload_internal.h file.
2832 * All include files that may be needed (public and some others
2833 included by the public headers) by application developers are
2834 now copied to the ./includes directory. It does not copy any
2835 internal headers. Affected file Makefile.defines.pre and all
2836 Makefile.am's under lib/ and subdirs.
2838 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2840 * Do not change the ~/.silc directory's permissions automatically.
2841 Affected file irssi/src/silc/core/clientutil.c.
2843 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2845 * Do not cancel the protocol in silc_server_close_connection
2846 it might cause recursion. Now cancelled in the function
2847 silc_server_free_sock_user_data. Affected file silcd/server.c.
2849 * Fixed the silc_server_remove_clients_by_server to regenerate
2850 the channel keys correctly finally. Added also new function
2851 silc_server_remove_clients_channels to actually do it.
2852 Affected file silcd/server.c.
2854 * Fixed the silc_server_new_channel to not crash by giving
2855 wrong router to the new channel. Affected file is
2856 silcd/packet_receive.c.
2858 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2860 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2861 which is given as argument to the silc_client_alloc now.
2862 It can be used to configure the client and set various parameters
2863 that affect the function of the client.
2865 * The USERS command in server did not check whether the channel
2866 is private or secret. Affected file silcd/command.c.
2868 * Added new argument to the USERS command in protocol specification.
2869 The USERS command now can take the channel name as argument
2870 as well. Added support for this in client and server and
2871 updated the protocol specs.
2873 * Completed the GETKEY command in client. It can be now used
2874 to fetch also servers public key not only some clients.
2875 Affected files lib/silcclient/command[_reply].c.
2877 * Added silc_client_get_server to return server entry by the
2878 server name. Affected files lib/silcclient/silcapi.h and
2881 * Redefined the IDENTIFY command in protocol specification to be
2882 more generic. It now can be used to query information about
2883 any entity in the SILC Network, including clients, servers and
2884 channels. The query may be based either the entity's name
2885 or the ID. Added support for this in both client and server.
2887 Affected files silcd/command.c and lib/silcclient/command.c
2888 and command_reply.c.
2890 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2891 the _from_client and _from_server functions. Affected file
2894 * Added silc_client_get_channel_by_id_resolve to the file
2895 lib/silcclient/silcapi.h to resolve channel information by
2896 its ID. Added also silc_client_get_channel_by_id that
2897 does not resolve it from the server.
2899 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2901 * Added SilcServerEntry context into the client library
2902 to represent one server. The INFO command now allocates
2903 these to save the resolved server info. For now on the
2904 client library will also keep information about servers,
2905 connected and resolved with INFO.
2907 The INFO command now allocates the SilcServerEntry context
2908 and saves the server info there. The COMMAND_REPLY in
2909 the INFO now returns the parameters to application in
2910 same order as defined in the protocol specification.
2912 The entries are cached in the client->server_cache.
2914 * The INFO command is now issued after received the Client ID
2915 from the server. Affected file lib/silcclient/client.c.
2917 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2918 to the application as the mode changer might be server.
2919 It is guaranteed that NULL is not returned anymore to the
2920 application. Affected file lib/silcclient/client_notify.c.
2922 The ID Type is now also passed to the application so that
2923 it can check whether the returned entry is SilcClientEntry
2926 Added new function silc_client_get_server_by_id to return
2927 the server entry by ID. Affected files are the
2928 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2930 * Do not create the channel in the Irssi SILC Client when issuing
2931 the JOIN command but when received the sucessful JOIN command
2932 reply. Otherwise the channel might get created even though we
2933 could not join it. The Affected file is
2934 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2936 * Fixed a channel joining bug in router. The router must also
2937 check the channel modes, invite and ban lists etc. when serving
2938 the JOIN command sent by normal server. Affected file is
2939 silcd/command.c. The router now resolves the client's
2940 information from the server who sent the JOIN command if it
2941 does not know it, and processes the JOIN command only after
2944 * Changed the SilcCommandCb to take new argument; void *context2.
2945 Affected file lib/silccore/silccommand.h
2947 The second argument in the command callbacks in the server now
2948 includes the SilcServerCommandReplyContext if the command was
2949 called as pending command callback from the command reply.
2950 Otherwise it is NULL. When called as pending the status of the
2951 command reply will be checked and if it was erronous the
2952 error will be sent to the original sender of the command.
2953 This way the client always receives the error messages even
2954 though the server was actually the one who received the error
2955 when it resent the command to router, for example. Affected
2956 files silcd/command[_reply].[ch].
2958 * Fixed sending WHOWAS command's error message to client if
2959 the requested client could not be found. It was missing.
2962 * Changed the CMODE and CUMODE commands reply arguments in the
2963 protocol specification. The Channel ID is now sent in both
2964 of the commands to identify the channel. Implemented this
2965 new feature to the client and server. Affected files
2966 lib/silcclient/command_reply.c and silcd/command.c.
2968 * Made better checks for invite and ban lists in the JOIN
2969 command in server. Affected file silcd/command.c.
2971 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * The server now performs the incoming host IP/DNS lookup
2974 using the silc_socket_host_lookup and thus does not block
2975 the server anymore. Affected file silcd/server.c.
2977 * Completed the multi-thread support for SILC Scheduler in
2978 the lib/silcutil/silcschedule.c.
2980 * Fixed the configure.in.pre to detect the pthread correctly
2983 * Fixed a deadlock in silc_task_queue_wakeup in the file
2984 lib/silcutil/silctask.c.
2986 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2988 * Added new function silc_schedule_wakeup that is used in
2989 multi-threaded environment to wakeup the main thread's
2990 schduler. It needs to be used when a thread adds a new task
2991 or removes a task from task queues. After waking up, the
2992 scheduler will detect the task queue changes. If threads
2993 support is not compiled in this function has no effect.
2994 Implemented the wakeup mechanism to both Unix and WIN32
2995 systems. Affected files are lib/silcutil/silcschedule.[ch],
2996 lib/silcutil/unix/silcunixschedule.c and the
2997 lib/silcutil/win32/silcwin32schedule.c.
2999 * Added new function silc_task_queue_wakeup to wakeup the
3000 scheduler by the specified task queue. Affected file
3001 lib/silcutil/silctask.[ch].
3003 * The silc_socket_host_lookup_start now wakes up the scheduler
3004 after adding the timeout task. Affected file is
3005 lib/silcutil/silcsockconn.c.
3007 * The silc_socket_host_lookup is synchronous now if the threads
3008 support is not compiled in. However, the callback is still
3009 called asyncronously through the scheduler, anyway. Affected
3010 file lib/silcutil/silcsockconn.c.
3012 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3014 * Added new function silc_socket_host_lookup to perform
3015 asynchronous IP and FQDN lookups for the socket connection.
3016 Affected files lib/silcutil/silcsockconn.[ch].
3018 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3020 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3021 that may or may not compile the mutex support in.
3023 Changed the silc_mutex_alloc interface. It allocates the
3024 mutex now to the sent pointer and returns TRUE or FALSE.
3026 Affected file lib/silcutil/silcmutex.h.
3028 * Wrote the SILC Task Queue interface to support multi-threads.
3029 Affected file lib/silcutil/silctask.[ch].
3031 * Wrote the SILC Scheduler to support multi-threads. Affected
3032 file lib/silcutil/silcschedule.c.
3034 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3037 in lib/silcutil/win32/.
3039 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3041 * Defined SILC Mutex API and SILC Thread API and implemented
3042 them for Unix. Affected files are
3043 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3044 lib/silcutil/unix/silcunixmutex.c and
3045 lib/silcutil/unix/silcunixthread.c.
3047 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3049 * Fixed the silc_server_remove_clients_by_server's channel
3050 key re-generation. The hash table handling was incorrect
3051 and would not work with many channels. Affected file is
3054 * Fixed some memory leaks around the server code.
3056 * Rewrote the silc_server_get_users_on_channel to support IPv6
3057 based Client ID's. Affected file silcd/server.c.
3059 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3060 specification. However, a separate document must be written
3061 to define the detailed signing procedure and the payload
3062 associated with the flag. Defined the flag to the
3063 lib/silccore/silcchannel.h as well.
3065 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3067 * Changed the dynamic tables to static size tables in the
3068 lib/silccrypt/silchmac.c.
3070 * Removed GCC dependencies from the code. A patch by cras.
3072 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3074 * Do not show the error "Error receiving packet bla bla"
3075 in server if it really was not an error (-2 means that reading
3076 is pending). Affected file silcd/server.c.
3078 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3080 * Fixed a possible crash in silc_server_remove_clients_by_server
3081 in silcd/server.c. Fixed there also some memory leaks.
3083 * Fixed the silc_idlist_replace_client_id. It could replace
3084 wrong key in the hash table. Affected file silcd/idlist.c.
3086 * Do not check whether there are global users on the channel
3087 if the channel->global_users is FALSE. Affected functions
3088 silc_server_remove_from_one_channel and
3089 silc_server_remove_from_channels in silcd/server.c. Also,
3090 do not check if the removed client is local as we can be
3091 sure that global client was not removed from the channel
3092 and checking for global users is not needed.
3094 * The silc_server_remove_clients_by_server now re-generates
3095 the channel keys correctly for those channels that had
3096 clients removed from them. Affected file silcd/server.c.
3098 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3100 * Found the reason of random crashes in the server. We weren't
3101 ignoring the SIGPIPE signal (which can be sent in write())
3102 and it crashed the server. Affected file silcd/silcd.c.
3104 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3106 * Assure that sock->user_data is not NULL in the function
3107 silc_server_packet_send in silcd/packet_send.c.
3109 * Disconnect the remote connection if it could not be added
3110 to any ID lists in the server. The affected file is
3113 * Check in silc_server_packet_send[_real/dest] that the
3114 socket is not disconnecting and ignore the data if it is.
3115 Affected file silcd/packet_send.c.
3117 * Define inline to __inline on native WIN32 compilation.
3118 Affected file includes/silcwin32.h.
3120 * Added some explicit type casts for inline code since MSVC
3121 require them. Affected files lib/silcutil/silcbuffer.h,
3122 lib/trq/silcdlist.h and lib/trq/silclist.h.
3124 * Print warning in log files from now on if the packet
3125 decryption fails. Affected file silcd/server.c.
3127 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3129 * Changed the `say' client operation's interface to accept
3130 new `type' argument to indicate the type of the message sent
3131 by the library. The application may filter the library's
3132 messages according the type. The affected file is the
3133 lib/silcclient/silcapi.h.
3135 * Added two new functions to lib/silcclient/silcapi.h:
3136 silc_client_del_client and silc_client_del_client_by_id.
3137 Affected file lib/silcclient/idlist.c.
3139 * Moved the clientincludes.h from includes/ to silc/ and
3140 serverincludes.h from includes/ to silcd/.
3142 * The modes for the CMODE and CUMODE are now passed as
3143 uint32 for application with COMMAND_REPLY. The affected
3144 file is lib/silcclient/command_reply.c.
3146 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3148 * /WHOIS without arguments shows client's own information.
3149 Affected file lib/silcclient/command.c.
3151 * Changed PING to not accept any arguments. The specs
3152 says that client can ping only the connected server so
3153 requiring an argument is not needed. Affected file is
3154 lib/silcclient/command.c.
3156 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3158 * Fixed a fatal bug in private message sending and reception
3159 encryption and decryption when using private message keys.
3160 The implementation was incorrect and did not follow the
3161 specification. It causd that some of the message were
3162 lost since it did not use the sending and receiving keys
3163 as the protocol suggests. This has been fixed and will cause
3164 incompatibilities with older clients when sending private
3165 message encrypted with private message keys. Affected files
3166 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3167 and various other in Irssi SILC Client.
3169 Added `responder' boolean argument to the functions
3170 silc_client_add_private_message_key[_ske] to indicate when
3171 the key is added as responder or initiator of the key
3174 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3176 * Removed the silc_ske_check_version function and created
3177 a SilcSKECheckVersion callback. Added also a function
3178 silc_ske_set_callbacks that is now used to set all SKE
3179 callbacks. The callback functions are not given to
3180 the SKE functions anymore, but this function is used to
3183 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3185 * Added `silc_version' argument to the silc_client_alloc
3186 to define the version of the application for the library.
3187 The library will use the version string to compare it
3188 against the remote host's (usually a server) version
3189 string. Affected file lib/silcclient/silcapi.h
3191 * Added the KE protocol context to Key Agreement context
3192 in client library so that we can abort the SKE if it
3193 is in process when we get timeout. Affected file is
3194 lib/silcclient/client_keyagr.c.
3196 * Do not resolve the client ID forever if it returns in the
3197 first time that such client does not exist. This was done
3198 for example with private message. Affected file is
3199 lib/silcclient/client_prvmsg.c.
3201 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3203 * Do not add regex.h for WIN32. The affected file
3204 includes/silcincludes.h.
3206 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3207 not work yet 100%. It generates the DLL's automatically
3208 when compiling with --with-win32 under cygwin.
3210 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3212 * lib/contrib/regex.c is not compiled on WIN32.
3214 * Added silc_net_get_socket_opt function to the
3215 lib/silcutil/silcnet.h.
3217 * Added includes/silcwin32.h for WIN32 specific includes
3220 * Do not use ptime structure or any of the posix process
3221 functions on WIN32 in lib/silccrypt/silrng.c.
3223 * Added silc_gettimeofday to provide generic function
3224 for struct timeval on all platforms. Added the function
3225 to lib/silcutil/silcutil.h.
3227 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3229 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3230 library as they clearly belong there. As a plus side we
3231 can make the actual socket connection routines platform
3234 Added also new generic function silc_socket_read and
3235 silc_socket_write (that used to be silc_packet_[read/write].
3236 The implementation of these are platform specific.
3238 * Added WIN32 specific routines of silc_socket_[read/write]
3239 to lib/silcutil/win32/silcwin32sockconn.c.
3241 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3243 * Added preliminary support for native WIN32 compilation under
3244 cygwin (using the -mno-cygwin option for GCC) to the
3245 ./configure.in.pre. The --with-win32 now prepares the
3246 compilation for native WIN32.
3248 * Rewrote the SILC Scheduler interface in the file
3249 lib/silcutil/silcschedule.h. The scheduler is now context
3250 based and does not have anymore any global static scheduler.
3251 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3252 and created lib/silcutil/win32 directory for WIN32 based
3255 * Added Unix specific network routines to the
3256 lib/silcutil/unix/silcunixnet.c and the old
3257 lib/silcutil/silcnet.c includes now only generic routines.
3259 Added WIN32 specific network routines to the
3260 lib/silcutil/win32/silcwin32net.c.
3262 * Added Unix specific utility functions from the
3263 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3265 * Added WIN32 SILC Scheduler to the file
3266 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3269 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3271 * Do not handle JOIN notify in the server if the target client
3272 is not registered (idata->registered == FALSE). The affected
3273 file is silcd/packet_receive.c.
3275 * Update the nickrec->founder in event_cumode in the Irssi SILC
3276 client. Affected file irssi/src/silc/core/silc-channels.c.
3278 * Fixed the CUMODE_CHANGE notify handling in the server when
3279 server and router are announcing their clients on channels.
3280 Now the mode changes are saved and notified correctly. The
3281 affected file is /silcd/packet_receive.c.
3283 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3284 They really did not replace the cache entry in the ID Cache.
3285 Now they do that. Affected file silcd/idlist.c.
3287 * Fixed the KICK notify handling in the Irssi SILC client to
3288 update the channel records so that the kicked client does not
3289 appear to be on the channel. The affected file is
3290 irssi/src/silc/core/silc-channels.c.
3292 * Always update the conn->current_channel when executing command
3293 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3295 * Fixed the KILL notify handling in Irssi SILC client to remove
3296 the killed client on all channels.
3298 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3300 * Fixed the silc_parse_command_line to remove extra spaces
3301 from the start and end of the arguments. Affected file is
3302 lib/silcutil/silcutil.c.
3304 * Cancel and free any active protocol in the function
3305 silc_server_close_connection. Affected file silcd/server.c.
3307 * Cancel and free any active protocol in the function
3308 silc_client_close_connction. Affected file is
3309 lib/silcclient/client.c.
3311 * Do not execute the KILL command for clients that are in
3312 history (ie. they are not in the network). Affected file is
3315 * Fixed KILL notify handling, client does not crash anymore.
3316 Affected file irssi/src/silc/core/silc-channels.c.
3318 * Reduced the default packet buffer size from 2048 to 1024 in
3319 lib/silccore/silcpacket.c.
3321 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3322 counter to the SKE context that is incresed when the SKE library
3323 performs async operation outside the library. If the outside
3324 process frees the SKE context and FREED status will be set
3325 and the library will detect after the sync operation that the
3326 libary is freed. The affected files are
3327 lib/silcske/silcske[_status].[ch].
3329 * Resolve the client entry information in the function
3330 silc_client_channel_message to assure that NULL pointer is not
3331 passed as client entry to the application. */
3333 * Fixed the task timeout calculation to assure that there is
3334 never negative timeouts. The affected file is
3335 lib/silcutil/silcschedule.c.
3337 * Fixed the channel user mode notification sending in server.
3338 It was sent point-to-point to the router (or to server by router)
3339 but it needs to be destined to a channel. The routines now
3340 supports sending the channel user mode notifys to the channels
3341 when announcing clients and channels. Affected files are
3342 silcd/server.c and silcd/packet_receive.c.
3344 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3345 It did not actually replace the old channel entry in the cache.
3346 Affected file lib/silcclient/client_notify.c.
3348 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3350 * Fixed a possible crash in silc_packet_send_prepare. It now
3351 assures always that there is enough space in the buffer and
3352 at the tail area of the buffer (for MAC).
3354 Fixed the inbound buffer reallocation in silc_packet_read.
3355 It was old code and did not handle the reallocation correctly.
3358 The affected file is lib/silccore/silcpacket.c.
3360 * Fixed buffer overflow in silc_parse_nickname in the file
3361 lib/silcutil/silcutil.c.
3363 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3365 * make install generates new server keys only if there is not
3368 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3370 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3371 Added check that if the NOREPLY is set then we will not send
3372 the away message. This avoids infinite loop of away messages
3373 if both clients are away. The affected file is
3374 lib/silcclient/client_prvmsg.c.
3376 * Fixed client crash if /NICK was given without arguments.
3377 Affected file lib/silcclient/command.c.
3379 * Server does not send the invite list in INVITE command back
3380 to the client if the list was not altered. Added this notion
3381 to the protocol spec as well. Affected file silcd/command.c.
3383 Fixed possible crash in INVITE command by checking the
3384 value of silc_server_get_client_route command.
3386 * Fixed the INVITE notify type handling. The arguments are now
3387 taken in correct order and client does not crash. The affected
3388 file is irssi/src/silc/core/silc-channels.c.
3390 Removed the "Inviting xxx to channel" message from the
3391 client library away and let the application handle it.
3392 Affected file lib/silcclient/command.c. Added that message
3393 to Irssi SILC client's message formats.
3395 * Fixed CMODE command crash in client. It now checks the
3396 amount of arguments correctly and does not crash. The affected
3397 file is lib/silcclient/command.c.
3399 * Do not create new channel automatically in silc_channels_join
3400 but check whether the channel by that name already exists.
3401 Affected file irssi/silc/core/silc-channels.c.
3403 * Do not send the SERVER_SIGNOFF to router if the disconnected
3404 entity was the router. Affected file silcd/server.c.
3406 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3407 SILC client as it was missing from there.
3409 Added the handling of the KICK notify to the Irssi SILC client
3410 as it was missing. Added "you have been kicked" message to
3411 Irssi SILC client's message modules formats.
3413 Added the handing of the KILL notify to the Irssi SILC client
3414 as it was missing. Added the kill message module formats
3417 The affected file is irssi/src/silc/core/silc-channels.c.
3419 * The router did not save the channel mode the server announced.
3420 Affected file silcd/packet_receive.c.
3422 * Fixed a possible crash in INFO command in server. If the
3423 server did not provide the server info it crashed. Affected
3424 file silcd/command.c.
3426 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3428 * Fixed the GETKEY command in the server to check also the
3429 global list. Otherwise the GETKEY would not work correctly
3430 in normal SILC server. Affected file silcd/command.c.
3432 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3434 * Fixed GETKEY crash, it crashed if the command did not succseed.
3436 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3438 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3439 is now real and not just an macro interface to GMP.
3441 Removed the entire GMP from the source tree and imported new
3442 NSS MPI library instead. Reason for removing GMP is that it is
3443 extremely large and compiles extremely slow. The NSS MPI
3444 is only a few files and compiles in less than 10 seconds.
3445 The speed is also about the same as GMP. The MPI is imported
3446 to lib/silcmath/mpi.
3448 If the system has GMP installed we will still use the GMP.
3449 If it is not then the NSS MPI will be compiled.
3451 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3453 * Merged a long nickname (127 characters long) crash bugfix from
3454 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3456 * Merged a freed memory reference bugfix from Irssi CVS tree.
3457 Affected file irssi/src/core/commands.c.
3459 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3461 * Added the server's public key sving and verification to the
3462 server when performing the SKE. This was missing and the
3463 remote server's (or router's) public key was accepted without
3464 checking whether we have it previously or trust it at all.
3465 Affected file silcd/protocol.c.
3467 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3469 * Check in the silc_server_timeout_remote if protocol is active
3470 and make sure that the protocol's final callback is called so
3471 that all memory if freed. Affected file silcd/server.c.
3473 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3475 * silc_server_whois_send_reply crashed the server if the nickname
3476 was 127 characters long. Affected file silcd/command.c.
3478 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Added sanity check to the silc_server_new_client. If the hostname
3481 is provided inside username then check that the provided hostname
3482 really is the same as the resolved one. If the hostname was not
3483 resolved then check it from the public key. Affected file is
3484 silcd/packet_receive.c.
3486 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3487 if the server disconnected us and the connection is not valid
3488 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3490 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3491 the library to the lib/silcutil/silcutil.[ch].
3493 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Close log file after open. Affected file
3496 lib/silcutil/silclog.c.
3498 * Check whether sock == NULL in silc_client_send_packet and return
3499 if it is. Affected file lib/silcclient/silcclient.c.
3501 * Check rec->entry == NULL in the Irssi SILC Client before
3502 sending the channel message. Affecte file is
3503 irssi/src/silc/core/silc-servers.c.
3505 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3507 * Merged a splitted window bugfix from Irssi CVS tree. The
3508 affected file is irssi/src/fe-text/textbuffer-view.c.
3510 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3511 It did not print nickname.
3513 * Improved the distributions system a bit.
3515 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3518 irssi/src/fe-text/gui-window.c.
3520 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3521 to in-active server. The affected file is
3522 irssi/src/silc/core/client_ops.c.
3524 * Resolve the client in USERS command reply if the entry does
3525 not have username resolved. The affected file is
3526 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3527 command to WHOIS command to really resolve stuff. The USERS
3528 is not used any more in any critical section so WHOIS can
3529 be used even though it might be slower than IDENTIFY.
3531 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3534 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Changed the protocol API a bit more consistent in the
3537 lib/silccore/silcprotocol.[ch].
3539 * Changed the following headers to ROBODoc format:
3541 lib/silccore/silcpayload.h
3542 lib/silccore/silcprotocol.h
3543 lib/silccore/silcsockconn.h
3545 All core library headers are now formatted.
3547 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3549 * Fixed a bug in Irssi SILC client; do not show that you are
3550 server/router operator if you really are not. Affected file is
3551 irssi/src/silc/core/client_ops.c.
3553 * Renamed silc_command_free_payload to silc_command_payload_free.
3554 Affected file lib/silccore/silccommand.h
3556 * Added silcmath.h to include the prototoypes of various routines
3557 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3560 * Changed the following headers to ROBODoc format:
3562 lib/silccore/silcchannel.h
3563 lib/silccore/silccommand.h
3564 lib/silccore/silcid.h
3565 lib/silccore/silcidcache.h
3566 lib/silccore/silcmode.h
3567 lib/silccore/silcnotify.h
3568 lib/silccore/silcpacket.h
3569 lib/silcmath/silcmath.h
3571 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3573 * Added checking to the server code not to start the server if
3574 ciphers and stuff are not configured properly. Affected files
3575 silcd/serverconfig.[h] and silcd/server.c.
3577 * Changed the layout of the header files of the public interfaces
3578 in the SILC libraries. The new layout supports ROBODoc
3579 documentation tool (and some others) so that it is easy to create
3580 a library reference manual. All the other headers and source
3581 code must still follow the CodingStyle document. Also source
3582 code must not include these ROBODoc stuffs, only the headers.
3583 Furthermore, all public interface headers must now be named
3584 by using `silc' prefix, example: silcapi.h, silccipher.h.
3585 Some files were renamed due to this. All the other headers
3586 must not be used as public interfaces. I will update the
3587 CodingStyle document later. Changed following headers, so far:
3589 lib/silcclient/silcapi.h
3590 lib/silccore/silcauth.h
3591 lib/silccore/silcprivate.h
3592 lib/silccrypt/silcdh.h
3594 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Removed silc_client_packet_send_flush from the client library
3599 as it is not needed. Affected file lib/silcclient/client.[ch].
3601 * Added printing of message of unresolved authentication method
3602 to the Irssi SILC client. Added it to the module formats.
3603 Removed the same message from the client library.
3605 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Added new distribution feature, DISTLABEL. Every distribution
3608 can define own preprocessor label that can be used in the
3609 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3610 file distributions, acconfig.h.pre and prepare.
3612 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Added Makefile.defines_int to include the actual definitions
3615 for Makefile.defines.in. Tested the new distribution system,
3616 created distributions and tested installation.
3618 * Added AWAY message printing to the Irssi SILC client. Added
3619 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3621 * Added SCONNECT command to call the SILC's CONNECT command.
3622 Cannot use CONNECT directly since Irssi uses that internally.
3623 Affected file irssi/src/silc/core/silc-servers.c.
3625 Added ACTION local command. It is same as ME command but takes
3626 the channel as mandatory argument.
3628 Rewrote some of the Irssi's help files to suite for SILC
3631 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Added Makefile.defines[.in] that should for now on be included
3634 in all Makefile.am file in the source tree. That file includes
3635 all common compilation definitions for SILC source tree.
3637 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3639 * Minor changes to the ./prepare script to change the package
3640 name according the distribution name to the configure.in.
3642 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3644 * Created new distribution system. Added file `distributions'
3645 that defines all the distributions that can be created out of
3646 the SILC source tree. The ./prepare script now reads that
3647 file to determine how to prepare the distributions. The
3648 first argument to the ./prepare is the name of the distribution
3649 and second is the version of the distribution. If given
3650 without arguments it creates the default (toolkit) distribution
3651 with the default version (defined in ./prepare).
3653 All Makefile.am files that are subject to the distributions
3654 are now named as Makefile.am.pre. These are ./Makefile.am
3655 and lib/Makefile.am. Others may be changed later.
3657 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Added invite list, ban list, some key management and connection
3660 error message printing to module formats in the Irssi SILC client.
3662 * Added new silc_client_set_away_message to set the away message
3663 that is back to the person who sent private message. The
3664 affected file lib/silcclient/silcapi.h and the
3665 lib/silcclient/client_prvmsg.c.
3667 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3669 * Fixed the private message sending in the Irssi SILC client,
3670 added local command KEY to the Irssi SILC client.
3672 Added key management and key agreement message formats to the
3673 irssi/src/fe-common/silc/module-formats.[ch].
3675 Added USERS (alias WHO) printing, server/router operator
3676 indication and LIST command printing to the module formats.
3678 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Fixed channel joining notify handling, cumode notify handling
3681 from Irssi SILC client.
3683 * Added SILC specific module-formats to the Irssi SILC client so
3684 that SILC specific message hilighting, colors etc is possible.
3685 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3687 Added channel mode, channel user mode, actions, notices,
3688 whois and whowas printing to the the module-formats.c.
3690 * Fixed a bug in channel deletion in the server. The channel
3691 is not left to the cache even if the channel founder auth mode
3692 is set when there are no users anymore on the channel. Affected
3693 file silcd/server.c.
3695 * The silc_net_localhost now resolves the entire hostname including
3696 the domain name. Affected file lib/silcutil/silcnet.c.
3698 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * Changed the ask_passphrase client operation to be ascynchronous.
3701 It has now a completion callback and a context that the
3702 application must call after it has got the passphrase from
3703 the user. Affected files lib/silcclient/silcapi.h,
3704 lib/silcclient/protocol.c, lib/silcclient/command.c and
3707 Added SilcAskPassphrase callback that the application calls
3708 to deliver the passphrase to the library.
3710 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3711 The public key verification and especially a certificate
3712 verification is asynchronous procedure.
3714 Added new SILC_SKE_STATUS_PENDING status to indicate the
3715 request is pending and a callback will be called to finalize
3718 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3719 indicate that remote end did not send its public key (or
3720 certificate), even though we require it. Added check for this
3721 condition in the SKE. This was a security bug, now fixed.
3723 Defined new SilcSKEVerifyCbCompletion callback that is called
3724 when the verification process is completed.
3726 The affected files lib/silcske/silcske_status.h and
3727 lib/silcske/silcske.[ch].
3729 * Changed the verify_public_key client operation to be async
3730 as well. Defined SilcVerifyPublicKey callback that is used to
3731 indicate the success of the public key verification process.
3733 Changed the server and client to use the new async client
3736 * Changed the Irssi SILC client's internal scheduler to be called
3737 twice as many times as it used to be. As a result the client
3738 should be a bit faster now. Affected file is
3739 irssi/src/silc/core/silc-core.c.
3741 * Added support to Irssi SILC client of asynchronous public key
3742 verification and passphrase inquiry. Affected file is
3743 irssi/src/silc/core/silc-core.c.
3745 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3747 * Do not say "You have left channel %s" in client library.
3748 Moved it to the application. Affected files are
3749 lib/silcclient/command.c and silc/client_ops.c.
3751 * Fixed silc_client_get_clients. Command context was not
3752 duplicated and was freed memory in the callback. Affected
3753 file lib/silcclient/idlist.c.
3755 * Do not say "you are now talking..." on JOIN command in the
3756 client library. The appliation must handle it.
3758 * Do not say ".. changed topic to" in command reply in the
3759 client libary. The application must handle it.
3761 * Fixed TOPIC command sending in the client library.
3763 * Fixed a memory leak in silc_client_command_free in the file
3764 lib/silcclient/command.c.
3766 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Imported a modified version of Irssi client to the source tree.
3769 The Irssi will be used to create a new client called
3770 Irssi SILC. Imported to irssi/.
3772 Added silc_core_init_finish function to the Irssi. Affected
3773 file irssi/configure.in.
3775 A lot changes in the Makefile.ams around the irssi tree.
3777 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Do not rehash if the new size is same as the old size of the
3780 hash table, in the silc_hash_table_rehash*. The affected file
3781 lib/silcutil/silchashtable.c.
3783 * Replaced hash_table_del_by_context calls from the server
3784 (when channel->user_list and client->channels) to the
3785 hash_table_del as it is sufficient and faster.
3787 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Added silc_hash_table_list, silc_hash_table_get and the
3790 SilcHashTableList structure to provide an alternative way to
3791 traverse the hash table. The affected files are
3792 lib/silcutil/silchashtable.[ch].
3794 * Changed the server's idlist routines to use the hash table
3795 routines to optimize the code.
3797 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Replaced the client entry's `channel' list and channel entry's
3800 `user_list' list to hash tables for optimized lookup. Changed
3801 the code to use the hash table interface around the code.
3802 Affected file lib/silcd/idlist.[ch].
3804 * Added `auto_rehash' boolean argument to the function
3805 silc_hash_table_alloc to indicate whether the hash table should
3806 auto-rehash when it thinks is appropriate time. It will
3807 increase the hash table size if the there is twice as much
3808 entries in the table than the size of the table, and will
3809 decrease the size if there are twice as less entries than
3810 the size of the table.
3812 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3814 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3816 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3818 * silc_idcache_purge_by_context deletes the entry now by context
3819 as it is supposed to do. Affected file lib/silccore/idcache.c.
3821 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3822 client is not anymore valid (WHOWAS givens the info) and not
3823 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3825 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Removed the `data' and `data_len' arguments from the ID Cache
3828 interfaces and added `name' argument. ID Cache does not handle
3829 anymore the binary data only a names associated with given ID.
3831 * When hashing a Client ID with silc_hash_id the entire ID is
3832 not hashed anymore, instead only the hash of the Client ID is
3833 hashed. This way we can access the Client ID from the cache
3834 with Client ID but with the hash of the ID (which is a hash of
3835 the nickname) as well without any difference in performance.
3837 Added also silc_idcache_find_by_id_one_ext to do one on one
3838 searching when we have the actual ID. Added also function
3839 silc_hash_client_id_compare. The affected files are
3840 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3842 * When hashing the name associated with a ID it is always done
3843 in lowercase. This way we can access the cache without worrying
3844 about case-sensitivity, even though, for example nicknames are
3847 * Fixed a bug in server with channel message sending. It put
3848 wrong ID type as destination ID. The affected file
3849 silcd/packet_send.c.
3851 * silc_idcache_del_by_context now deletes from all hash tables
3852 by context. Affected file lib/silccore/idcache.c.
3854 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Changed the client library to use the new ID Cache interface.
3857 Changes around the source tree.
3859 * Added silc_hash_table_rehash_ext to rehash with specific
3860 hash function. Affected file lib/silcutil/silchashtable.[ch].
3862 * Added silc_hash_string_compare to compare two strings in the
3863 hash table. Affected file lib/silcutil/silcutil.[ch].
3865 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Added new function silc_idcache_del_by_context into the
3868 lib/silccore/idcache.[ch].
3870 * Changed the server's ID list routines to use the new ID Cache
3871 interface. Changes around the source tree.
3873 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3875 * Added silc_hash_table_del[_by_context]_ext functions in to the
3876 lib/silcutil/silchashtable.[ch].
3878 Removed silc_hash_table_find_all* routines and added new
3879 silc_hash_table_find_foreach to replace them.
3881 Added silc_hash_table_replace_ext function as extended
3882 replacing function. Separated the simple hash table interface
3883 from the extended hash table interface in the file
3884 lib/silcutil/silchashtable.h.
3886 * Fixed minor bugs and changed it to use some of the new
3887 hash table functions in lib/silccore/idcache.c
3889 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3891 * Added new function silc_hash_table_find_all to return all keys
3892 in the hash table by the specified key. As the hash table is
3893 collision resistant it also makes it possible to have several
3894 duplicate keys in the hash table. This function may be used to
3895 find all of the keys from the hash.
3897 Added user_context arguments to the SilcHashFunction,
3898 SilcHashCompare and SilcHashDestructor to deliver user specified
3901 Added new fuctions silc_hash_table_find[_all]_ext to do
3902 extended lookup with specified hash and compare functions and
3903 specified user contexts.
3905 Added new function silc_hash_table_add_ext to add the key
3906 with specified hash function and user context.
3908 Added new function silc_hash_table_foreach to traverse all
3909 entrys in the hash table. Added SilcHashForeach callback
3912 Added new function silc_hash_table_del_by_context to delete
3913 the entry only if the context associated with the key matches.
3915 Affected files are lib/silcutil/silchashtable.[ch].
3917 * Removed silc_hash_[server/client/channel]_id and added just
3918 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3919 silc_hash_id_compare to compare two ID's using as the hash table
3920 comparison function. Added also silc_hash_data to hash
3921 binary data and silc_hash_data_compare to compare it.
3923 * Removed silc_idlist_find_client_by_hash as it is not needed
3924 anymore. Affected file silcd/idlist.[ch].
3926 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3927 to use internally the SilcHashTable. The new ID Cache is a lot
3928 faster than the old one. Some of the ID Cache interface was also
3929 rewritten and obsolete and stupid functions were removed.
3931 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Added entry_count field to the SilcHashTable to keep the number
3934 of the entries in the table. Implemented the function
3935 silc_hash_table_rehash. Added new function
3936 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3938 Fixed a minor bug in silc_hash_table_free.
3940 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3941 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3942 into the lib/silcutil/silcutil.[ch].
3944 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3946 * Implemented a collision resistant hash table into the
3947 lib/silcutil/silchashtable[ch]. See the header and the source
3948 for the SilcHashTable API.
3950 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Merged dotconf version 1.0.2 into lib/dotconf.
3954 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Do not compile anything in lib/silcsim/* if the SIM support
3957 is not enabled. The tree should now compile without problems
3960 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3962 * Compiled the SILC under cygwin. Compiled and tested briefly
3963 without problems. More tests needed. The SIMs didn't compile
3966 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3968 * Fixed possible crash in silc_get_username in the
3969 lib/silcutil/silcutil.c.
3971 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Fixed a va_arg in silc/client_ops.c.
3975 * Oops, RC5 routines were named AES and caused some problems
3976 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3978 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Added new SilcIDIP structure into the lib/silccore/id.h and
3981 replaced the old `ip' fields from all SILC ID's to that type.
3982 This is a step towards IPv6 support.
3984 The silc_id_get_len takes now the ID as an extra argument.
3985 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3986 both IPv4 and IPv6 based ID's.
3988 The affected files are lib/silccore/id.[ch] and other files
3989 around the tree using these routines.
3991 * Removed the ID length arguments in server from various
3992 silc_server_send_notify_* routines -> they are not needed
3995 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3997 * Fixed memory leak in silc_encode_pem_file in the file
3998 lib/silcutil/silcutil.c.
4000 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Check minor version as well in the SKE. Affected files are
4003 silcd/protocol.c and lib/silcclient/protocol.c.
4005 * Added --identifier option to the server so that an identifier
4006 can be when creating the public key for the server. Affected
4007 file is silcd/silcd.c.
4009 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4010 lib/silccrypt/silcpkcs.c.
4012 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Register default ciphers and stuff when using -C option with
4015 the server. Affected file sildc/silcd.c.
4017 * Put back the servers public key filename format, it is better
4018 than the new one. For now, the client keys are saved with the
4019 new filename format. The affected file silc/client_ops.c.
4021 * Implemented the Cipher API for the rest of the ciphers that
4022 did not implement it or implemented it the wrong way.
4024 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Register default ciphers and stuff when using the -S option
4027 in the client. Affected file silc/silc.c. Same also when
4028 creating new key pair with -C option.
4030 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Fixed the silc_verify_public_key client operation function to
4033 save the public keys differently. The fingerprint is now
4034 used as filename and not the hostname. This way also the
4035 client keys are saved uniquely and not with hostnames. The
4036 affected file is silc/client_ops.c.
4038 * Trimmed the silc_hash_fingerprint function to remove extra
4039 whitespaces from the end of the fingerprint. The affected
4040 file is lib/silccrypt/silchash.c.
4044 * Added silc_cipher_register_default function to register all
4045 default ciphers. It can be used when configuration files
4046 does not exist and the application does not want any specific
4047 ciphers in any specific order.
4049 The SilcDList is now used as silc_cipher_list dynamically
4050 allocated cipher list. Removed the static list all together
4051 and now all ciphers must be allocated to the dynamic list.
4052 The silc_cipher_alloc routine was changed to check only the
4055 All silc_cipher_* routines that used to return int returns
4058 The affected files lib/silccrypt/silccrypt.[ch].
4060 * The same thing was done to silc_hash_* as for silc_cipher_*
4061 routines. Affected files lib/silccrypt/silchash.[ch].
4063 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4064 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4065 Added also silc_pkcs_[un]register[_default] functions.
4066 Removed the data_context from the PKCS API.
4068 * Added silc_hmac_register_default function to register default
4069 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4070 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4071 to unregister all hmacs at once.
4073 * Register the default ciphers, hash functions, PKCSs and HMACs
4074 if client's configuration file does not exist. The affected
4077 * The client did not load the hash functions from the SIM
4078 modules at all. Added support for this. Affected file is
4079 silc/clientconfig.c.
4081 * When decoding public key with silc_pkcs_public_key_decode, check
4082 the supported algorithm only if PKCS are registered. Affected
4083 file lib/silccrypt/silcpkcs.c. The same was done with the
4084 silc_pkcs_private_key_decode.
4086 * Fixed the SILC List routines to keep the list always in order.
4087 It used to change the list's order when traversing the list but
4088 not it preserves the order. Affected file lib/trq/silclist.h.
4090 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * Added the client library to use the SilcSocketConnection's
4093 reference counter (by silc_socket_dup) to prevent the bug that
4094 the socket object may be freed underneath async operation.
4096 * The name resolv library checking fixes in the configure.in.pre.
4099 * Created new version of the protocol drafts for future
4100 development. The -03 drafts are the ones that will be changed
4101 in the trunk now and the -02 will remain as they are.
4103 * Send list of CUMODE notifys to the router when announcing
4104 the channel users to the router. Affected file silcd/server.c.
4105 If the router receiving channel founder CUMODE for a channel
4106 that already has channel founder it will send CUMODE notify
4107 to the sender to remove the channel founder rights from the
4108 announced client. Affected file silcd/packet_receive.c.
4110 * The CUMODE notify may now use Server ID as well as the entity
4111 who changes the mode. Updated protocool specs.
4113 * Updated INSTALL and README files.
4115 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4117 * New web pages in the http://silc.pspt.fi. The pages was
4122 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Implemented the [DenyConnectin] config section in the server.
4125 Added silc_server_config_denied_conn to check whether incoming
4126 connection is denied. Affected file silcd/serverconfig.[ch].
4128 * Do not check the ports when checking the incoming configuration
4129 data if the port is 0, meaning any. Affected file is
4130 silcd/serverconfig.c.
4132 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4134 * Fixed buffer overflow in silc_string_compare in the file
4135 lib/silcutil/silcutil.c.
4137 * Fixed double free in silc_server_command_leave in the file
4140 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4142 * Fixed the version checking in the server. Affected file is
4145 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Fixed the configuration data fetching when accepting new
4148 connections in the server. Affected file silcd/server.c.
4150 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4152 * Added `sender_entry' argument to the function
4153 silc_server_packet_relay_to_channel so that we can check
4154 whether some destination actually belongs to the same route
4155 the sender belongs (ie, we must not resend the packet to the
4156 sender). Affected file silcd/packet_send.[ch].
4158 * Added `servername' field to the SilcClientEntry in the server
4159 to hold the name of the server where client is from. Affected
4160 file is silcd/idlist.h.
4162 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Moved the channel message encrypting in the router betwen
4165 router connections from silc_server_channel_message to the
4166 silc_server_packet_relay_to_channel since we want to check
4167 whether we have anybody channel before encrypting anything.
4168 Affected files silcd/packet_[receive/send].c.
4170 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Fixed the [AdminConnection] server config section to support
4173 multiple entries. Affected file silcd/serverconfig.c.
4175 * Added support into the server to check the validity of the
4176 incoming connection before executing any KE or authentication
4179 * The connection configuration is now saved to the KE and
4180 connection auth protocol contexts and not fetched anymore in
4181 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4183 * The local hosts listenning address and port is also resolved
4184 now when starting the server. We want to have the socket object
4185 to include the real address and port for the listener. Added
4186 new function silc_net_check_local_by_sock into the files
4187 lib/silcutil/silcnet.[ch].
4189 * Fixed a broadcast bug in server -> do not broadcast if we
4192 * Fixed a routing bug. Do not route broadcast packets ever.
4193 Broadcast packets must be processed always and not routed since
4194 they may be destined to some other host than yourself and thus
4195 would get routed without no good reason. Affected file is
4198 * Added function silc_server_config_is_primary_route to check
4199 whether primary router connection has been configured (a router
4200 configuration that we are initiating). If there is not, we
4201 will assume that there is only two routers in the SILC network
4202 and we will use the incoming router connection as our primary
4203 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4205 * Changed the order of the broadcasting. Broadcast _after_ the
4206 packet has been processed not before. Affected file is
4209 * Fixed a [ClientConnection] parsing bug. The port was never
4210 parsed correctly thus resulting to port 0. Affected file
4211 silcd/serverconfig.c.
4213 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4214 argument and did not set the broadcast packet flag. Affected
4215 file silcd/packet_send.c. Fixed same bug in the function
4216 silc_server_send_notify as well.
4218 * If we receive NEW_ID packet for our own ID in the server, ignore
4221 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Removed the nickname from the Private Message Payload.
4226 Updated the code and the protocol specs.
4228 * Updated protocol specs for submitting to the IETF.
4230 * Tweaked the Random Number Generator a bit. Affected file
4231 lib/silccrypt/silcrng.c. Exported a new function
4232 silc_rng_[global]_add_noise which can be used to add more
4235 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Do not parse packets with different timeout when protocol
4238 is active -> may cause problem with rekey. Affected file
4241 * When server receives signoff notify it must not create
4242 new channel key if the client is on any channels since the
4243 sender of the signoff notify will create it.
4245 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Added printing of error messages during SKE protocol from the
4248 failure packet sent by server during SKE. Affected file
4251 * Removed the client's failure_callback handling with timeout
4252 and handle it immediately when received.
4254 * The SKE library returned wrong type in SUCCESS and FAILURE
4255 packets. They must be 32 bit MSB not 16 bit MSB.
4257 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Ok, rewrote the logic of the re-key and now it seems to work.
4260 I tested it on high traffic with frequent re-keys without
4261 problems. Added hmac_receive (and renamed hmac to hmac_send)
4262 in SilcClientConnection in lib/silcclient/client.h and
4263 in SilcIDListData in silcd/idlist.h. Also, removed the
4264 SilcPacketParserContext's cipher and hmac fields as they are
4265 not needed anymore and actually caused some problems when
4266 the ciphers and hmac's changed underneath the packet parser.
4268 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * If re-key protocol is active then process the incoming packets
4271 synchronously since we must assure that icoming packets encrypted
4272 with the old key is processed before the new keys is set to
4273 use. This is true other packets than for REKEY packets.
4274 Affected file silcd/server.c. The same was done to client library
4275 as well, affected file lib/silcclient/client.c.
4277 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4279 * Fixed bug in client and server to accept the force send if
4280 the packet is send from silc_[server/client]_packet_process
4281 function. Otherwise the packets are never delivered, oops.
4283 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Disable force sending of packets when REKEY protocol is active.
4286 We must assure that no packet is sent directly when rekey is
4287 performed. All packets must be sent through packet queue.
4288 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4289 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4290 function is silc_[server/client]_packet_send_real to check
4293 * Replaced the SIM paths from example config files to
4294 /usr/local/modules. Also, make install creates now
4295 /usr/local/silc/logs directory to hold all the SILC server
4298 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Made the configure.in.pre work on Solaris. Patch by salo.
4302 * Made all ciphers compatible with non-x86 machines. Defined
4303 CBC mode macros into lib/silccrypt/ciphers_def.h.
4305 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4307 * Fixed the make install.
4309 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * When MAC computation fails the silc_packet_decrypt returned 0
4312 even though it was supposed to return -1. Fixed this. The
4313 affected file is lib/silccore/silcpacket.c.
4315 * Do not replace the config files in /etc/silc (in make install)
4316 if they already exist. Affected file ./Makefile.am.
4318 * Do not send re-key packets immediately but through packet queue.
4319 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4321 * Changed silc_net_check_host_by_sock to return FALSE if the
4322 IP/DNS could not be resolved. Though, it returns the IP address
4323 now even if it could not resolve it (but returns also FALSE).
4324 Affected file lib/silcutil/silcnet.[ch].
4326 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4328 * Added silc_pkcs_decode_identifier to decode the public key's
4329 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4330 Added also silc_pkcs_free_identifier. Added also new context
4331 SilcPublicKeyIdentifier.
4333 * Added -S option to the silc client. It is used to dump the
4334 contents of the specified public key file.
4336 * Changed the PKCS api to return the public key length when
4337 setting the public key.
4339 * Fixed a fatal bug in the public and private key file loading.
4340 Affected file lib/silccrypt/silcpkcs.c.
4342 * Execute the packet parsing for client with zero (0) timeout
4343 if the protocol is active. Affected file silcd/server.c.
4345 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Made the key generation options to the silcd program. Added
4348 -C option, equivalent to client's option.
4350 * Added new [ServerKeys] config section to the server. It
4351 configures the server's public and private key.
4353 * Defined generic Public Key Payload into the protocol
4354 specification to send specific type of public keys and
4357 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4358 public key or certificate.
4360 * Implemented the GETKEY command to the server and to the
4361 client library and on user interface.
4363 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Made preliminary `make install' work.
4367 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Added SilcServerRekey context into silcd/idlist.h.
4371 * Added the PFS support as defined in the specification to the
4372 SKE protocol. Affected files lib/silcske/*.c.
4374 * Added `ske_group' field to the SilcServerRekey context to hold
4375 the number of the SKE group that is used with PFS in re-key.
4376 Affected file silcd/idlist.h.
4378 * Added PFS re-key support to the server. Affected file is
4381 * Added silc_protocol_cancel to cancel execution of the next
4382 state of the protocol. Affected file is
4383 lib/silccore/silcprotocol.[ch].
4385 * Added the re-key support with and without PFS to the client
4386 library. Re-key is performed once in an hour, by default.
4388 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4389 Added silc_client_rekey_callback and silc_client_rekey_final.
4390 Affected files are lib/silcclient/protocol.[ch] and
4391 lib/silcclient/client.[ch].
4393 * Removed the `hmac_key' and `hmac_key_len' fields from the
4394 SilcClientConnection structure; not needed. Affected file is
4395 lib/silcclient/client.h.
4399 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Do not ask whether user wants to use the negotiated private key
4402 for private messages, just use it. Affected file is
4403 silc/local_command.c.
4405 * Added `send_enc_key' and `enc_key_len' fields to the
4406 SilcIDListData structure since they are needed in the re-key
4407 phase. Affected file is silcd/idlist.[ch].
4409 * Implemented the simple re-key protocol into the server.
4410 Affected files silcd/server.c and silcd/protocol.[ch]. The
4411 re-key will be performed once in an hour, by default.
4413 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4414 Added silc_server_rekey, silc_server_rekey_callback and
4415 silc_server_rekey_final.
4417 * Removed Tunneled flag from the protocol. Updated the code
4418 and the specifications.
4420 * Adde `pfs' field to the SilcIDListData to indicate whether
4421 the PFS is to be performed in the re-key. Affected file is
4424 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4427 int64 of at least the xintXX size. If void * is less that 4
4428 bytes uint32 * will be used. Defined bool as boolean.
4430 * Changed _ALL_ unsigned long and unsigned int to uint32,
4431 unsgined short to uint16 in the source tree.
4433 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4434 not handle clients that has entry->data.registered == FALSE.
4435 They are not in the network anymore. Affected file is
4438 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * Implemented the sending of the SERVER_SIGNOFF notify in the
4441 server. Affected file is silcd/server.c.
4443 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4444 Added also silc_notify_payload_encode_args into the
4445 lib/silccore/silcnotify.[ch].
4447 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4448 Affected file silcd/packet_receive.c.
4450 * Implemented the SERVER_SIGNOFF notify handling in the client
4451 library. Affected file lib/silcclient/client_notify.c. Also,
4452 implemnted the printing of the SERVER_SIGNOFF info to the
4453 application. Affected file silc/client_ops.c.
4455 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4456 if the deleting was successful. Affected file silcd/idlist.[ch].
4458 * Added support for public key authentication in the connection
4459 authentication protocol in the client library. Affected file
4460 lib/silcclient/protocol.c.
4462 * Changed the server's silc_idlist_get_clients_by_* interface
4463 to support already allocated array so that new entries may be
4464 added to pre-allocated array. Affected file silcd/idlist.[ch].
4465 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4466 and command replies.
4468 * All command reply functions in the server now calls the
4469 pending command callback even if error occured. This way the
4470 error will be delivered to the client as well. Affected files
4471 silcd/command.c and silcd/command_reply.c.
4473 * Fixed INFO command to return local server's info if no server
4474 was provided. Affected file lib/silcclient/command.c.
4476 * Removed RESTART command for good. Updated the code and the
4479 * Rewrote parts of the task system. It is a bit simpler now.
4480 Removed unsued task priorities. The affected files are
4481 lib/silcutil/silctask.[ch].
4483 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Moved the USERS printing from the library to the application.
4486 Affected files lib/silcclient/command.c and silc/client_ops.c.
4488 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * Added channel key re-key support. The re-key is perfomed
4493 only by the router and is done once in an hour. Added `rekey'
4494 field to the SilcChannelEntry in the server. Affected files
4495 silcd/server.c and silcd/idlist.h.
4497 * Added silc_task_unregister_by_context into the file
4498 lib/silcutil/silctask.[ch].
4500 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Added SILC_UMODE_GONE mode to indicate when the client is not
4503 present in the SILC network. Added also support to the local
4504 command AWAY that will set this mode. Added support of showing
4505 "xxx is gone" in WHOIS command. The USERS command shows the
4506 gone status as well.
4508 * Fixed setting server and router operator privileges in the
4509 server's UMODE command. Affected file silcd/command.c.
4511 * Merged the SKE KE1 and KE2 payloads into one payload. The
4512 new KE payload is equivalent to the old KE2 payload.
4514 Cleaned up the SKE Start Payload parsing. It now uses the
4515 simple buffer unformatting to do the parsing. A lot faster
4518 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4519 to the SKE that is used to indicate whether both of the SKE
4520 parties should perform authentication. By default only the
4521 responder performs authentication. By setting this flag also
4522 the initiator must do authentication. By default it is unset
4523 since in normal SKE case, client to server connection, only
4524 the responder should do authentication. When doing SKE between
4525 two clients both should perform authentication. Updated the
4526 code and the protocol specs.
4528 * A little fix to IDENTIFY command in the server. Search the
4529 client first by hash not nickname. Affected file is
4532 * Fixed the silc_client_close_connection to support closing
4533 the client to client connections wihtout deleting too much
4534 data. Affected file lib/silcclient/client.c.
4536 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4537 are received if protocol used to be active but is not anymore
4538 the application would crash due to NULL pointer dereference.
4539 Affected files silcd/server.c and lib/silcclient/client.c.
4541 * Added `hash' field to the SilcClientConnection to include
4542 the hash function negotiated in the SKE protocol.
4544 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4545 to set the channel founder authentication data. A client can
4546 claim the founder rights later by providing the authentication
4547 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4548 This way the channel founder can regain the channel founder
4549 privileges even it is left the channel. This works only on
4550 local server and the client must be connected to the same
4551 server to be able to regain the founder rights. Updated the
4552 protocol specs accordingly.
4554 Added support to the CMODE command in the client to set the
4555 founder auth data. Read the README to see how to set it.
4557 Added support to the CUMODE command to claim the founder
4558 rights. Read the README to see how to do it.
4560 Added support for the founder authentication to the Channel
4561 Entry in the server. Affected file silcd/idlist.h.
4563 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4564 server's CMODE command. Affected file silcd/command.c.
4566 * Added the following new functions into lib/silccore/silcauth.[ch]:
4567 silc_auth_get_method and silc_auth_get_data.
4569 * The server now saves the remote hosts public key to the
4570 SilcIDListData pointer. Affected file silcd/protocol.c.
4572 * The normal server now does not remove the channel entry from
4573 the cache if the founder authentication data is set. It used
4574 to remove it if the founder was the last one on the channel on
4575 the server and left the channel. The auth data is saved and
4576 if the channel is re-joined later the old entry is used with
4577 the old auth data. Affected files silcd/command_reply.c and
4580 * Removed the `pkcs' field from the SilcIDListData structure
4581 in the server; it is not used. Affected file silcd/idlist.h.
4583 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Fixed packet processing on slow links. Partial packets were
4586 never re-processed because the incoming data buffer was cleared
4587 by the application. Application must not directly clear the
4588 sock->inbuf, the packet processing routines handle it. Fixed
4589 this in client library and in server.
4591 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Fixed the WHOIS and IDENTIFY send reply function to really
4594 check whether to send list or just one entry. Affected file
4597 * Cleaned up the LEAVE command's channel key distribution. The
4598 affected file silcd/command.c.
4600 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4601 can enforce the channel mode as well. In that case the ID
4602 includes the ID of the server. The code now enforces the
4603 mode change if the router have different mode than the server.
4605 * The notify client operation with CMODE_CHANGE notify can now
4606 return NULL client_entry pointer if the CMODE was not changed
4607 by client. Application must check for this.
4609 * Added <Server ID> argument to INFO command to support server
4610 info fetching by Server ID.
4612 * Added silc_server_announce_get_channel_users to get assembled
4613 packets of channel users of the specified channel. Affected
4614 file silcd/server.[ch].
4616 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4617 was freed underneath the ID Cache.
4619 * Re-announce clients when the server received CHANNEL_CHANGE
4620 notify from the router. Affected file silcd/packet_send.c.
4622 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4625 crashed since it did not handle the fact that there is no cipher
4626 called "3" and didn't check the error condition. Now fixed.
4628 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4629 flag. It can be used to send message requests.
4631 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Implemented the RESTART command in the client.
4635 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4636 notice type messages. Added notice printing to the user
4639 * The channel keys are not re-generated if the channel's mode
4640 is PRIVKEY, ie private key on the channel exists. Affected
4641 files silcd/server.c and silcd/command.c.
4643 * Fixed a little bug in channel message delivery when channel
4644 private keys are set in the server. Affected file is
4645 silcd/packet_send.c.
4647 * Changed the setting on channel->on_channel = TRUE from the
4648 silc_client_save_channel_key to the JOIN command reply. The
4649 key payload is not received if the private channel key is set.
4650 Affected file lib/silcclient/command_reply.c and the
4651 lib/silcclient/client_channel.c.
4653 * When the CMODE_CHANGE notify is sent and the channel private
4654 key mode is removed the channel key must be re-generated in
4655 other cells as well. Added this support for the router in the
4656 silcd/packet_receive.c.
4658 * Added new local command NOTICE to send notice message on
4659 channel. Affected file silc/local_command.[ch].
4661 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Added new local command ME to the client. It is used to send
4664 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4665 some action. Affected file silc/local_command.[ch].
4667 * Changed channel_message and private_message client operations
4668 to deliver the message flags to the application. Added also
4669 the `flags' arguments to the silc_client_send_channel_message
4670 and silc_client_send_private_message functions. Affected file
4673 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Redefined the Private Message Payload to support private message
4676 keys and to support the new private message flags. Updated
4677 the protocol specs. Flags makes it possible to have for example
4678 CTCP style messages.
4680 * Added new type SilcPrivateMessagePayload and defined an API
4681 for it in the lib/silcclient/silcprivate.[ch].
4683 * Tested private message private keys successfully. Tested the
4684 private message key set, unset and list commands with the new
4687 * Redefined the Channel Message Payload to include the channel
4688 message flags (equal with private message flags) to support
4689 for example CTCP style messages.
4691 * Defined some of the message (for channel and private message)
4692 flags. Updated the protocol specs and added the flags to the
4693 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4695 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Added SilcKeyAgreementStatus type to the key agreement routines
4698 to indicate the current status and error if one occured.
4699 The status types are defined in the lib/silcclient/silcapi.h.
4701 * Added new local command KEY that is used to set and unset private
4702 keys for channels, set and unset private keys for private messages
4703 with remote clients and to send key agreement requests and
4704 negotiate the key agreement protocol with remote client. The
4705 key agreement is supported only to negotiate private message keys,
4706 it currently cannot be used to negotiate private keys for channels,
4707 as it is not convenient for that purpose.
4709 * Fixed a minor pending callback setting bug in the function
4710 silc_client_get_client_by_id_resolve, now the function works.
4711 Affected file lib/silcclient/idlist.c.
4713 * Added function silc_net_get_local_port to get local bound
4714 port by socket. Added to lib/silcutil/silcnet.[ch].
4716 * Added `sockets' and `sockets_count' fields to the SilcClient
4717 object. They hold the sockets of the listenning sockets in
4718 the client. Listenning sockets may be for example the key
4719 agreement server. Affected file lib/silcclient/client.[ch].
4720 Added functions the silc_client_add_socket and the
4721 silc_client_del_socket. They are exported to the application
4724 * Added ~./silc/clientkeys to support other client's public keys.
4726 * Renamed verify_server_key client operation to verify_public_key
4727 and added one argument to indicate the type of the connection
4728 (server, client etc.).
4730 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Added silc_server_connection_auth_request to handle the
4733 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4734 silcd/packet_receive.[ch].
4736 * Added silc_server_send_connection_auth_request into the
4737 silcd/packet_send.c to send the connection auth request packet.
4739 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4742 * Fixed the public key authentication in responder side in the
4743 server. The `auth_data' pointer includes the SilcPublicKey
4744 not the path to the public key. Affected file silcd/protocol.c.
4746 * Implemented the public key authentication in the initiator side
4747 in the server. Affected file silcd/protocol.c.
4749 * Removed the [RedirectClient] config section from the server
4750 configuration. Is not needed and I don't want to implement it.
4752 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4754 * Cleaned up the CMODE command in the server. It now works
4755 correctly and supports all the modes defined in the protocol.
4756 Affected file is silcd/command.c.
4758 * Added `hmac_name' field to the SilcChannelEntry in the server
4759 to hold the default HMAC of the channel. It can be set when
4760 creating the channel (with JOIN command). Affected files
4763 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4764 type to indicate the change of the current cipher and hmac
4765 on the channel. Client can safely ignore the <cipher> argument
4766 (if it chooses to do so) since the CHANNEL_KEY packet will
4767 force the channel key change anyway. The <hmac> argument is
4768 important since the client is responsible of setting the new
4769 HMAC and the hmac key into use.
4771 * Fixed the CMODE command in the client library as well.
4773 * Tested CMODE command in router environment successfully.
4775 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4777 * Show the version of the remote client (or server) when connecting
4778 to the server. It is logged to the log file. Affected file
4779 is silcd/protocol.c.
4781 * Fixed the KILLED notify handling in the client library. The
4782 client must be removed from all channels when receiving the
4785 Also, do not remove the client entry when giving the KILL
4786 command but when the KILLED notify is received.
4788 * Removed silc_idlist_find_client_by_nickname from the server.
4789 Not needed anymore. Affected files silcd/idlist.[ch].
4791 * Implemented the CHANNEL_CHANGE notify type handling to the
4792 server. Affected file silcd/server.c.
4796 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4799 notify between routers.
4801 * Implemented the INVITE command correctly to the server.
4803 * Implemented the INVITE notify type handling in the server.
4805 * Implemented the INVITE command to the client library and on the
4808 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Added function silc_server_get_client_resolve to find the
4811 client entry by ID from all ID lists and then resolve it
4812 (using WHOIS) if it cannot be found. Affected file is
4815 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Implemented the BAN command to the client library.
4819 * The JOIN command in the server now checks the invite list
4822 * Changed the silc_command_reply_payload_encode_va and the
4823 silc_command_payload_encode_va to support that if argument is
4824 NULL it ignores and checks the next argument. Affected file
4825 lib/silccore/silccommand.c.
4827 * Added silc_server_send_notify_ban to send the BAN notify
4828 type between routers.
4830 * Chaned the silc_notify_payload_encode to support that if
4831 argument is NULL it ignores and checks the next argument.
4832 Affected file lib/silccore/silcnotify.c.
4834 * Tested ban lists in router environment successfully.
4836 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Implemented BAN command to the server, in silcd/command.[ch].
4840 * Removed the BAN and INVITE_LIST modes from the CMODE command
4843 * Added function silc_string_match to regex match two strings.
4844 Affected files lib/silcutil/silcutil.[ch].
4846 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * Redefined parts of the SilcChannelEntry in the server to support
4849 the new ban and invite lists.
4851 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4853 * Redefined the INVITE command. The same command can be used to
4854 invite individuals to the channel but also to manage the invite
4855 list of the channel (to add to and remove from the invite list).
4856 Updated the protocol specs.
4858 * Added new command SILC_COMMAND_BAN that can be used to manage
4859 the ban list of the channel. Updated the protocol specs.
4861 * Removed the channel modes: the SILC_CMODE_BAN and the
4862 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4863 in the CMODE command. The equivalent features are now available
4864 using INVITE and BAN commands. Updated the protocol specs.
4866 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4867 in the network about change in the current ban list. The notify
4868 type is not used by the client.
4870 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4871 support the invite lists.
4873 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Added new function silc_string_regexify that converts string
4876 including wildcard characters into regex string that can
4877 be used by the GNU regex library. Added into the file
4878 lib/silcutil/silcutil.[ch].
4880 Added silc_string_regex_combine to combine to regex strings
4881 into one so that they can be used as one regex string by
4882 the GNU regex library. Added into the file
4883 lib/silcutil/silcutil.[ch].
4885 Added silc_string_regex_match to match two strings. It returns
4886 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4888 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Imported GNU regex to the soruce tree into lib/contrib.
4891 Fixed some compiler warning from the regex.c.
4893 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Fixed MOTD command in the server to work in router environment.
4897 * Fixed the MOTD command in the client library to support
4898 the server argument in the command.
4900 * Added `nickname_len' argument to the silc_idlist_add_client
4901 in the server, as the `nickname' argument may be binary data
4904 * Added silc_idlist_get_channels to return all channels from
4907 * Implemented LIST command to the server. Affected file is
4910 * Implemented the LIST command to the client library and on the
4913 * Added [<user count>] argument to the LIST command reply.
4914 With private channels the user count is not shown.
4916 * Updated TODO and README.
4918 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4920 * The client entry's data.registered must be TRUE even with
4921 global client entry on global client list. The data.registered
4922 is used to check whether the client is anymore in the network,
4923 for example with WHOWAS command so it must be valid.
4925 * Fixed the WHOWAS command in the server. It now actually works
4926 in router environment. Added function into silcd/command_reply.c
4927 silc_server_command_reply_whowas_save.
4929 * Added silc_idlist_purge function to the silcd/idlist.c
4930 to periodically purge the ID Cache.
4932 * Fixed INFO command in the server. It works now in router
4933 environment. Added <server name> argument to the INFO command
4934 reply. Updated the protocol specs.
4936 * Fixed minor bug in silc_idcache_purge to not purge if the
4937 expire value is zero.
4939 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4940 they were buggy because of the WHOWAS information.
4942 * Fixed local command MSG to handle the async resolving of
4943 the remote client properly. It used to fail the first MSG.
4944 Affected file silc/local_command.c.
4946 * Added `data_len' field to SilcIDCache context.
4948 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4950 * Update TODO. Todo in commands in the server.
4952 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4954 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4955 used by routers as broadcast packet to inform other routers
4956 about the changed user mode.
4958 Implemented the notify handling in the server. Affected file is
4959 silcd/packet_receive.c. Added the function
4960 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4962 * Added new generic Channel Payload and deprecated the New Channel
4963 Payload. The New Channel Payload is now the generic Channel
4966 * Added new argument `mode' to the silc_server_send_new_channel
4967 as it is required in the Channel Payload now.
4969 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4970 and created a new and real SilChannelPayload to represent the
4971 new generic Channel Payload. Implemented the encode/decode
4972 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4974 * Added silc_server_get_client_channel_list to return the list
4975 of channels the client has joined for WHOIS command reply.
4976 Affected file silcd/server.[ch].
4978 * Implemented the channel list sending in the WHOIS command reply
4979 in server and in the client.
4981 Implemented the channel list displaying on the user interface
4982 as well. Affected file silc/client_ops.c.
4984 * Added silc_channel_payload_parse_list to parse list of Channel
4985 Payloads. It returns SilcDList list of SilcChannelPayloads.
4986 Client for example can use this function to parse the list of
4987 channels it receives in the WHOIS command reply. The caller
4988 must free the list by calling silc_channel_payload_list_free.
4989 Affected files lib/silccore/silcchannel.[ch].
4991 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Added one new argument <user mode> to the WHOIS command reply
4994 to return the mode of the user in SILC. Updated the protocol
4997 Implemented it to the server and client.
4999 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Fixed the mode printing on the user interface on joining.
5002 Affected file silc/client_ops.c.
5004 * Implemented the UMODE command and user modes in general to the
5005 client library and to the user interface.
5007 * Implemented the UMODE command to the server.
5009 * The server now sends UNKNOWN_COMMAND error status if client sends
5010 unknown command. Affected file silcd/command.c.
5012 * All server commands now handle the command identifier the right
5013 way when sending the command reply to the client. The client can
5014 use to identify the command replies with the identifier.
5016 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * Added silc_server_get_client_route to resolve the route to
5019 the client indicated by the client ID. Affected file is
5022 * Added silc_server_relay_packet as general function to relay
5023 packet to arbitrary destination. This deprecates functions
5024 like _send_private_message_key, _relay_notify etc. Affected
5025 file is silcd/packet_send.[ch].
5027 Removed silc_server_send_key_agreement,
5028 silc_server_send_private_message_key and
5029 silc_server_packet_relay_notify functions from the file
5030 silcd/packet_send.[ch].
5034 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5035 server. Affected file silcd/packet_receive.[ch].
5037 * Implemented the KILL command to the client. Implemented the
5038 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5039 Affected files lib/silcclient/command[_reply].c and
5040 lib/silcclient/client_notify.c. Implemented the KILL notify
5041 printing in the user inteface.
5043 * Fixed a lot silc_parse_nick memory leaks from the client
5044 library in the file lib/silcclient/command.c.
5046 * Changed the silc_server_send_notify_on_channels's `sender'
5047 argument from SilcSocketConnection to SilcClientEntry to
5048 check the sender as entry and not as connection object and not
5049 to send to the client provided as argument. The affected file
5050 is silcd/packet_send.[ch].
5052 * The notify packets that are destined directly to the client used
5053 to not to be processed by the server. Now changed that and the
5054 server processes all notify packets. After relaying the packet
5055 to the client the notify packet is processed in the server.
5057 * The silc_server_free_client_data now checks whether there is
5058 pending outgoing traffic for the client and purges the data to
5059 the network before removing the client entry.
5061 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5064 an client is killed from the SILC Network. Updated the protocol
5067 Added new function silc_server_send_notify_killed to the
5068 silcd/packet_send.[ch].
5070 * Added function silc_server_packet_relay_notify to relay notify
5071 packets that are destined directly to a client. In this case
5072 the server does not process the notify packets but merely relays
5073 it to the client. Affected file silcd/packet_send.[ch].
5075 Added also silc_server_packet_process_relay_notify to check
5076 whereto relay the notify. Affected file is
5077 silcd/packet_receive.[ch].
5079 * Implemented the KILL command to the server.
5083 * Added the backup schema desgined last fall to the protocol
5084 specs for everyone to see. The specification is in the
5085 *-spec-xx.txt draft and the packet type definitions for the
5086 backup routers is in *-pp-xx.txt draft. Thusly, added also
5087 new packet type SILC_PACKET_CELL_ROUTERS.
5089 * A big security problem in the implementation discovered. The
5090 signoff of an client did not cause new channel key generation
5091 which it of course should've done. The channel keys must be
5092 always re-generated when client leaves (or signoffs) the channel.
5093 The silc_server_remove_from_channels funtion now handles
5094 the channel key re-generation.
5096 * Added `sender' argument to the silc_server_send_notify_on_channels
5097 to not to send the client provided as argument. Affected file
5098 silcd/packet_send.[ch].
5100 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Implemented OPER and SILCOPER commands into the server and
5105 * Added silc_auth_verify and silc_auth_verify_data to verify
5106 the authentication directly from the authentication payload.
5107 It supports verifying both passphrase and public key based
5108 authentication. Affected file lib/silccore/silcauth.[ch].
5110 * Added `hash' field to the SilcIDListData structure. It is the
5111 hash negotiated in the SKE protocol. Affected file is
5114 * Slight redesigning of the SilcAuthPayload handling routines.
5115 Do not send SilcPKCS but SilcPublicKey as argument.
5117 * Implemented the public key authentication support to the
5118 serverconfig. The public key is loaded from the provided path
5119 and saved as authentication data to void * pointer. Thus,
5120 changed the unsigned char *auth_data to void *auth_data;
5122 * Fixed SHUTDOWN command to send the reply before the server
5123 is shutdown. :) Affected file silcd/command.c.
5125 * Fixed fatal bug in CONNECT command. The hostname was invalid
5126 memory and server crashed. Affected file silcd/command.c.
5128 * Fixed fatal bug in CLOSE command. The server_entry became
5129 invalid but was referenced later in the command. Affected file
5132 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5134 * Fixed fatal bug in failure packet handling. Server ignored
5135 the failure and thus crashed when it came.
5139 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5142 that the command may be executed only once in (about) 2 seconds.
5143 The old SILC_CF_LAG flag is same but allows command bursts up
5144 to five before limiting.
5146 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5147 server code. Various commands now includes the CF_LAG_STRICT
5148 flag to disallow any kind of miss-use of the command.
5150 * Fixed the silc_buffer_unformat to not to allocate any data
5151 if the length of the data is zero. It used to allocate the
5152 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5154 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5156 * Changed the format of AdminConnection configuration section
5157 in the server. Added username of the admin to the format.
5158 Affected files silcd/serverconfig.[ch].
5160 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5161 to return admin configuration data by host, username and/or
5164 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Implemented WHOWAS command to the server. Added the functions:
5168 silc_server_command_whowas_parse,
5169 silc_server_command_whowas_send_reply,
5170 silc_server_command_whowas_from_client and
5171 silc_server_command_whowas_from_server
5173 * Added <Client ID> argument to the WHOWAS command reply. Updated
5174 the protocol specs accordingly.
5176 * Implemented WHOWAS command and command_reply to the client
5179 Implemented the WHOWAS printing on the user interface.
5181 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Added new argument to the WHOWAS command reply, the real name.
5184 It is an optional argument. Updated the protocol specs.
5186 * Added SilcIDCacheDestructor callback that is registered when
5187 the SilcIDCache is allocated. The callback is called when
5188 an cache entry in the ID Cache expires, or is purged from the
5189 cache. Added into lib/silccore/idcache.[ch].
5191 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5192 to destruct the client entries when the cache entry expires.
5193 Other ID Cache's in server and in the client library ignores
5196 * If the ID Cache entry's `expire' field is zero then the entry
5197 never expires. Added boolean `expire' argument to the
5198 silc_idcache_add function in the lib/silccore/idcache.[ch].
5199 If it is TRUE the default expiry value is used.
5201 * Added silc_server_free_client_data_timeout that is registered
5202 when client disconnects. By default for 5 minutes we preserve
5203 the client entry for history - for WHOWAS command.
5205 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Added support to the server to enforce that commands are not
5208 executed more than once in 2 seconds. If server receives
5209 commands from client more frequently, timeout is registered
5210 to process the commands. Affected file silcd/command.c.
5211 Added new function silc_server_command_process_timeout.
5213 * Changed NICK_NOTIFY handling in client library to check that
5214 if the client's nickname was changed, so there is no need to
5215 resolve anything from the server.
5217 * Removed error printing from the WHOIS and IDENTIFY commands.
5218 If error occurs then it is ignored silently in the client library.
5219 The application, however, may map the received error to
5220 human readable error string. The application currently maps
5221 the NO_SUCH_NICKNAME error to string.
5223 * Made the command status message public to the application. Moved
5224 them from lib/silcclient/command_reply.c to
5225 lib/silcclient/command_reply.h. The application can map the
5226 received command status to the string with the
5227 silc_client_command_status_message function.
5229 * Added check to the server to check that client's ID is same
5230 as the Source ID in the packet the client sent. They must
5233 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Added dist-bzip hook to the Makefile.am to make bzip2
5236 compressed distributions.
5238 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5240 * Server now enforces the maximum length for the nickname and
5241 the channel as protocol specification dictates. 128 bytes for
5242 nickname and 256 bytes for channel name.
5244 * Moved the WHOIS printing to the application. The client libary
5245 does not print out the WHOIS information anymore, the application
5246 must do it. Renamed silc_client_command_reply_whois_print to
5247 the silc_client_command_reply_whois_save.
5249 The client's idle time is also sent to the application now, and
5250 the idle is shown on screen.
5252 * Added silc_client_command_reply_identify_save to save the
5253 received IDENTIFY entries.
5255 * Do not check for channel private keys in message sending and
5256 reception if the channel does not have the PRIVKEY mode set.
5257 Affected file lib/silclient/client_channel.c.
5259 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5262 just surfaced after chaning the JOIN procedure.
5264 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5266 * Added silc_client_get_clients_by_list to get client entries
5267 from Client ID list, that is returned for example by JOIN
5268 and USERS command replies. The application should use this
5269 function for example when JOIN command reply is received to
5270 resolve the clients already on the channel (library does not
5271 do that anymore as USERS command reply is not used in the JOIN
5272 procedure anymore). Affected files lib/silcclient/silcapi.h and
5273 lib/silcclient/idlist.c.
5275 * JOIN command reply and USERS command reply returns now SilcBuffer
5276 pointers instead of unsigned char pointers when returning
5277 the client list and mode list.
5279 * Added <Client ID> argument to the JOIN command reply, mainly
5280 for the server to identify for which client the command was
5281 originally sent. Updated protocol specs accordingly.
5283 * Added SilcDlist private_key pointer to the SilcChannelEntry
5284 in the client to support the channel private keys. Affected
5285 file is lib/silcclient/idlist.h.
5287 * Added SilcChannelPrivateKey argument to the function
5288 silc_client_send_channel_message so that application can choose
5289 to use specific private ke if it wants to. If it is not provided,
5290 the normal channel key is used, unless private keys are set.
5291 In this case the first (key that was added first) is used
5292 as the encryption key.
5294 * Implemented the support for channel private key handling.
5295 Implemented the following functions:
5297 silc_client_add_channel_private_key,
5298 silc_client_del_channel_private_keys,
5299 silc_client_del_channel_private_key,
5300 silc_client_list_channel_private_keys and
5301 silc_client_free_channel_private_keys
5303 Affected file lib/silcclient/client_channel.c.
5305 * Added the support for the private keys in the channel message
5306 sending and encryption and in the message reception and
5307 decryption. Affected funtions are
5308 silc_client_send_channel_message and silc_client_channel_message.
5310 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Added SKE's key verify callback to the client library's
5313 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5315 * Removed the statement that server (or router) must send USERS
5316 command reply when joining to the channel so that the client
5317 knows who are on the channel. Instead, the client list and
5318 client's mode list is now sent in the JOIN command reply to the
5319 client who joined channel. This is better solution.
5321 * Added function silc_server_get_users_on_channel and function
5322 silc_server_save_users_on_channel to the silcd/server.[ch].
5324 * Removed function silc_server_command_send_users from the
5327 * Do not show topic on the client library anymore. The topic is
5328 sent in the command reply notify to the application and the
5329 application must show the topic now.
5331 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Added client searching by nickname hash into the IDENTIFY and
5334 WHOIS commands in the server as they were clearly missing from
5335 them. Affected file is silcd/command.c.
5337 * Fixed a bug in private message receiving in the client library.
5338 The remote ID was freed and it wasn't supposed, now it is
5341 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Minor fix to the channel payload; allocate the data area, as it
5344 needs to be of specific length.
5346 * If the key agreement port is zero then the operating
5347 system will define the bound port. Affected files are
5348 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5350 * Added new function silc_channel_payload_decrypt into the file
5351 lib/silccore/silcchannel.[ch].
5353 * Moved the channel message etc, check from silc_packet_decrypt
5354 to applications. The library calls now a generic
5355 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5356 when the packet is either normal or special. This was done to
5357 allow more wide range of checking that was not allowed when
5358 the code was in library. Now applications can do virtually any
5359 checks to the packet and return to the library the decision how
5360 the packet should be processed. Affected files are
5361 lib/silccore/silcpacket.[ch].
5363 Added silc_server_packet_decrypt_check to the server and
5364 silc_client_packet_decrypt_check to the client library.
5366 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5367 to send with specified source and destination information.
5369 * Channel message delivery between routers was broken after the
5370 channel key distribution was fixed earlier. The channel key
5371 was used be to distributed to other routers as well which is not
5372 allowed by the protocol. Now this is fixed and channel keys
5373 really are cell specific and the channel message delivery between
5374 routers comply with the protocol specification.
5376 * Fixed various commands in server to check also the global list
5377 for the channel entry and not just the local list. The affected
5378 file silcd/command.c.
5380 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Added assert()s to buffer formatting and unformatting routines
5383 to assert (if --enable-debug) when error occurs. Affected
5384 file: lib/silcutil/silcbuffmt.c.
5386 * Changed to auto-reconnect to check whether the remote host is
5387 router and register the re-connect timeout if it is. It used
5388 to check that whether we are normal server, but router must do
5389 auto-reconnect with another router as well. Affected file
5392 * Removed the [<key len>] option from CMODE command as the cipher
5393 name decides the key length, nowadays. See the defined ciphers
5394 from the protocol specification.
5396 * Added [<hmac>] option to the CMODE command to define the HMAC
5397 for the channel. Added SILC_CMODE_HMAC channel mode.
5399 * Added [<hmac>] option for the JOIN command so that user can
5400 select which HMAC is used to compute the MACs of the channel
5403 * Added Hmac field to the Channel Message Payload. The integrity
5404 of plaintext channel messages are now protected by computing
5405 MAC of the message and attaching the MAC to the payload. The
5406 MAC is encrypted. Now, it is clear that this causes some
5407 overhead to the size of the packet but rationale for this is that
5408 now the receiver can verify whether the channel message decrypted
5409 correctly and also when private keys are set for the channel the
5410 receiver can decrypt the packet with several keys and check from
5411 the MAC which key decrypted the message correctly.
5413 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5414 lib/silccrypt/silccipher.[ch].
5416 * Added silc_hash_len to return the digest length into the
5417 lib/silcrypt/silchash.[ch].
5419 * Rewrote parts of Silc Channel Payload interface in the
5420 lib/silccore/silcchannel.[ch]. The encode function now also
5421 encrypts the packet and parse function decrypts it.
5423 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Fixed a minor formatting bug in the SKE's key material processing.
5426 It actually might have processed the keys wrong way resulting
5429 * Redefined the mandatory HMAC algorithms and added new algorithms.
5430 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5431 and hmac-md5 truncated to 96 bits. The mandatory is now
5432 hmac-sha1-96. Rest are optional (including the one that used
5433 to be mandatory). Rationale for this is that the truncated HMAC
5434 length is sufficient from security point of view and can actually
5435 make the attack against the HMAC harder. Also, the truncated
5436 HMAC causes less overhead to the packets. See the RFC2104 for
5439 * Added new [hmac] configuration section. The SKE used to use
5440 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5441 is of course wrong. The official names that must be proposed in
5442 the SKE are the ones defined in the protocol specification
5443 (hmac-sha1-96 for example). The user can configure any hmac
5444 using any hash function configured in the [hash] section. At
5445 least, the mandatory must be configured.
5447 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5449 * Added HMAC list to the SKE proposal list. It has now both
5450 hash algorithm list and HMAC list. This makes the protocol
5451 incompatible with previous versions. The SKE now seems to work
5452 the way it is supposed to work, for the first time actually.
5454 * Defined plain Hash algorithms to the protocol specification.
5457 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5459 * Implemented support for key agreement packets into the server.
5460 Added functions silc_server_key_agreement and
5461 silc_server_send_key_agreement. Other than these functions,
5462 server has nothing to do with this packet.
5464 * Added support for private message key packets into the server.
5465 Added functions silc_server_private_message_key and
5466 silc_server_send_private_message_key.
5470 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5471 called in the protocol's final callback instead in the END
5472 protocol state. This makes a little more sense and in the same
5473 time in client we can use the same protocol routines for normal
5474 key exchange and to key agreement packet handling as well.
5476 * Added to both client's and server's KE protocol context the
5477 SilcSKEKeyMaterial pointer to save the key material. We will
5478 bring the key material to the protocol's final callback by doing
5479 this. The final callback must free the key material.
5481 * Added SKE's packet_send callback into client's KE protocol
5482 context so that the caller can choose what packet sending function
5483 is used. This way we can use different packet sending when
5484 doing normal SKE when doing key agreement packet handling (in
5485 the key agreement packet handling we do not want to encrypt
5488 * Implemented the responder side of the key agreement routines
5489 in the client. The client can now bind to specified port and
5490 accept incoming key negotiation. The key material is passed
5491 to the application after the protocol is over.
5493 * Implemented the processing of incoming Key Agreement packet
5494 in the client. Added function silc_client_key_agreement to
5497 * Implemented the intiator side of the key agreement routines
5498 in the client. The client can now initiate key agreement with
5499 another remote client. The key material is passed to the
5500 application after the protocol is over.
5502 * Created client_keyagr.c to include all the key agreement
5505 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5506 SILC_TASK_CALLBACK except that it is not static.
5508 * Created client_notify.c and moved the Notify packet handling
5509 from the client.[ch] into that file.
5511 * Created client_prvmsg.c and moved all private message and
5512 private message key routines from the client.[ch] into that file.
5514 * Create client_channel.c and moved all channel message and
5515 channel private key routines from the client.[ch] into that file.
5517 * Changed silc_client_get_client_by_id_resolve to resolve with
5518 WHOIS command instead of IDENTIFY command, in the file
5519 lib/silclient/idlist.c.
5521 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Implemented the SKE's responder side to the Client library.
5525 * When FAILURE is received to the protocol do not trust it
5526 blindly. Register a timeout to wait whether the remote closes
5527 the connection as it should do it, only after that process the
5528 actual failure. This was changed to both client and server.
5530 * Added client_internal.h to include some of the structures
5531 there instead of client.h in lib/silcclient/.
5533 * Added function silc_task_unregister_by_callback to unregister
5534 timeouts by the callback function.
5536 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Some "Incomplete WHOIS info" errors has been appearing on the
5539 log files. Took away the entry->userinfo check from WHOIS
5540 reply sending. The entry->userinfo is now " " if client did not
5541 provide one. I thought this was fixed earlier but something
5542 is wrong still. Let's see if the error still appears.
5544 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Fixed a minor bug in the login when the channel key is
5547 re-generated in the server. It used to generate the key in
5548 wrong order and thus caused problems in the channel traffic.
5550 * Fixed a minor bug in channel key distsribution after
5551 KICK command. The key was not sent to the router even though
5554 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Added silc_ske_process_key_material_data as generic routine
5557 to process any key material as the SILC protocol dictates. The
5558 function is used by the actual SKE library but can be used by
5559 applications as well. This relates to the private message keys
5560 and the channel private keys since they must be processed the
5561 same way the normal SILC session keys. The protocol dictates
5562 this. Affected files: lib/silcske/silcske.[ch].
5564 Added also silc_ske_free_key_material to free the
5565 SilcSKEKeyMaterial structure.
5567 * Defined silc_cipher_set_key function to set the key for
5568 cipher without using the object's method function. The affected
5569 files: lib/silccrypt/silccipher.[ch].
5571 * Implemented silc silc_client_add_private_message_key,
5572 silc_client_add_private_message_key_ske,
5573 silc_client_del_private_message_key,
5574 silc_client_list_private_message_keys and
5575 silc_client_free_private_message_keys functions in the
5578 Added functions silc_client_send_private_message_key to send
5579 the Private Message Key payload and silc_client_private_message_key
5580 to handle incoming Private Message Key payload.
5582 * Added Cipher field to the Private Message Key payload to set
5583 the cipher to be used. If ignored, the default cipher defined
5584 in the SILC protocol (aes-256-cbc) is used.
5586 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Removed lib/silcclient/ops.h file.
5590 Redefined parts of the SILC Client Library API. Created new
5591 file silcapi.h that deprecates the ops.h file and defines the
5592 published Client Library API. Defined also private message key
5593 API and channel private key API into the file.
5595 This is the file that the application must include from the
5596 SILC Client Library. Other files need not be included by
5597 the application anymore.
5599 * Added new key_agreement client operation callback and also
5600 defined the Key Agreement library API for the application.
5602 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5604 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5605 is used by clients to request key negotiation between another
5606 client in the SILC network. If the negotiation is started it
5607 is performed using the SKE protocol. The result of the
5608 negotiation, the secret key material, can be used for example
5609 as private message key.
5611 Implemented the Key Agreement payload into the files
5612 lib/silccore/silauth.[ch].
5614 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Redefined ciphers for the SILC protocol. Added some new ciphers
5617 and defined the key lengths for the algorithms. Changed the
5618 code accordingly. The default key length is now 256 bits.
5620 * Fixed SKE key distribution function silc_ske_process_key_material
5621 when the key length is more than 128 bits. The default key
5622 length in SILC is now 256 bits.
5624 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5625 to indicate unsupported algorithm.
5627 * Renamed rijndael.c to aes.c and all functions as well.
5629 * Fixed a long standing channel key setting bug in client library.
5630 Weird that it has never surfaced before.
5632 * Fixed bug in channel deletion. If the entire channel is removed
5633 then it must also delete the references of the channel entry
5634 from the client's channel list as the client's channel entry and
5635 the channel's client entry share same memory.
5637 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Implemented CONNECT and SHUTDOWN commands in the client.
5641 * Implemented CLOSE command to the client.
5643 * Added the function silc_idlist_find_server_by_name into the
5644 files silcd/idlist.[ch].
5646 Added the function silc_idlist_find_server_by_conn into the
5647 files silcd/idlist.[ch].
5649 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * DIE command was renamed to SHUTDOWN. Updated the both code
5654 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5655 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5657 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5660 * Added function silc_server_create_connection function to create
5661 connection to remote router. My server implementation actually
5662 does not allow router to connect to normal server (it expects
5663 that normal server always initiates the connection to the router)
5664 so the CONNECT command is only good for connecting to another
5667 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5670 or some other client was kicked from the channel.
5672 Implemented the handling of the notify type to both client
5675 Implemented silc_server_send_notify_kicked to send the KICKED
5676 notify. It is used to send it to the server's primary router.
5678 * Implemented the KICK command into server and client.
5680 * Added `query' argument to the silc_idlist_get_client function
5681 to indicate whether to query the client from server or not if
5684 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5685 to indicate that the client is not channel founder.
5689 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5691 * Removed the rng context from SilcPacketContext structure and
5692 changed that the packet routine uses the Global RNG API.
5694 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Added support for quit message that client can "leave" on the
5697 channel when it quits the SILC. It is ditributed inside the
5698 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5700 Added silc_server_free_client_data that will take the
5701 signoff message as argument.
5703 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5705 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5707 * Updated parts of the protocol specification to keep it up
5710 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5712 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5713 payloads in one packet.
5715 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5716 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5717 use now the new List flag.
5719 * Also deprecated the following packet types: REPLACE_ID,
5720 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5722 * Added list support for Notify packet in server.
5724 * Added silc_server_send_notify_channel_change to send the
5725 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5726 the silc_server_send_replace_id.
5728 * Added silc_server_send_notify_nick_change to send the
5729 NICK_CHANGE notify type. Deprecates the function
5730 silc_server_send_replace_id.
5732 * Added silc_server_send_notify_join to send the JOIN notify type.
5733 Deprecates the function silc_server_send_new_channel_user.
5735 * Added silc_server_send_notify_leave to send LEAVE notify type.
5736 Deprecates the function silc_server_send_remove_channel_user.
5738 * Added silc_server_send_notify_cmode and
5739 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5740 types. Deprecates the silc_server_send_set_mode function.
5742 * Added SERVER_SIGNOFF notify type to indicate that server has
5743 quit. This means that all clients on the channel from that
5744 server will drop. This can be also used when netsplit happens.
5746 Deprecated REMOVE_ID packet type since it is not needed anymore
5749 Added silc_server_send_notify_server_signoff to send the
5750 SERVER_SIGNOFF notify type. Deprecates the function
5751 silc_server_send_remove_id.
5753 Added also silc_server_send_notify_signoff to send the
5754 SIGNOFF notify type.
5756 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5757 SILC protocol from this day on. Changed the protocol
5758 specification as well.
5760 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5761 notify type. It is used between routers to notify about
5762 topic changes on a channel.
5764 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5767 * Partly updated the protocol specification to comply with the
5768 changes now made. It is still though a bit outdated.
5770 * The JOIN notify type now takes one extra argument <Channel ID>.
5771 The packet used to be destined to the channel but now the
5772 JOIN type may be sent as list thus it is impossible to
5773 destine it to any specific channel. By adding this argument
5774 it is again possible.
5776 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Added CREDITS file. The CHANGES and CREDITS file will appear
5779 in the distribution as well.
5781 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5784 types in the server's silcd/packet_receive.c.
5786 * Implemented CMODE and CUMODE to work in router environment.
5788 * Fixed minor encoding and decoding buglet from the
5789 lib/silccore/silcmode.c.
5791 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5794 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5796 * Changed all SilcConfigServer* and silc_config_server* to
5797 SilcServerConfig* and silc_server_config*, respectively.
5800 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Associated the ID (client or server ID) to the Authentication
5803 Payload to avoid any possibility of forging. Updated the
5804 protocol specification and the code accordingly.
5806 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * The RSA key length is now save to the RsaKey context in the
5809 key generation process in lib/silccrypt/rsa.c. The key length
5810 is now used to figure out the maximum size of the block allowed
5811 to be encrypted/signed.
5813 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5814 is equivalent to the silc_mp_mp2bin but does not allocate any
5817 * Changed silc_mp_mp2bin API to take length argument. If it is
5818 non-zero then the buffer is allocated that large. If zero, then
5819 the size is approximated using silc_mp_sizeinbase, which however
5822 * Created Global RNG API which is global RNG that application can
5823 initialize. After initializing, any routine anywhere in the
5824 code (including library) can use RNG without allocating a new
5825 RNG object. This was done to allow this sort of use of the
5826 RNG in code that has no chance to allocate RNG object. All
5827 applications currently allocate this and many routines in the
5828 library use this. Affected file lib/silccrypt/silcrng.[ch].
5830 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5831 it to use the Global RNG API.
5833 * Defined Authentication Payload into protocol specification that
5834 is used during SILC session to authenticate entities. It is
5835 used for example by client to authenticate itself to the server
5836 to obtain server operator privileges.
5838 Implemented this payload into the lib/silccore/silcauth.[ch].
5839 Implemented also routines for public key based authentication
5840 as the new protocol specification dictates.
5842 Moved definitions of different authentication methods from
5843 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5845 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5846 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5847 silc_pkcs_verify_with_hash functions into the file
5848 lib/silccrypt/silcpkcs.[ch].
5850 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * The client entry's userinfo pointer must be always valid.
5853 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5854 will fail since it requires the userinfo. Now, the userinfo
5855 is allocated as "" if actual userinfo does not exist. Actually,
5856 it must exist and it is totally Ok to drop client connections
5857 that does not announce the userinfo. However, we will make
5858 this workaround for now.
5860 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5861 to return the remote port by socket.
5863 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5865 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5866 SILC_SERVER_PENDING_EXEC and added an new macro
5867 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5868 data or when error occurs while processing the pending command.
5870 Added new argument `destructor' into silc_server_command_pending
5871 and to the SilcServerCommandPending object. This destructor is
5872 now called after calling the pending callback or if error occurs
5873 immediately. If error occurs the actual pending callback won't
5874 be called at all - only the destructor. The destructor may be
5875 NULL if destructor is not needed.
5877 All this applies for client library code as well. Similar
5878 changes were made there as well for the pending commands.
5880 In the client, the application must now allocate the
5881 SilcClientCommandContext with the silc_client_command_alloc
5884 * Added reference counter to the SilcServerCommandContext. Added
5885 function silc_server_command_alloc and silc_server_command_dup
5888 Same type of functions added to the client library for the same
5891 * Removed the cmd_ident from IDListData away since it is now
5892 global for all connections. It is the command identifier used
5893 in command sending and with pending commands. The affected file
5896 * Added reference counter to the SilcSocketConnection objecet to
5897 indicate the usage count of the object. The object won't be
5898 freed untill the reference counter hits zero. Currently only
5899 server uses this, and client ignores it. The client must be
5900 set to use this too later. The affected files are
5901 lib/silccore/silcsockconn.[ch]. Added also the function
5902 silc_socket_dup to increase the reference counter.
5904 This was mainly added because it is possible that the socket
5905 is removed underneath of pending command or other async
5906 operation. Now it won't be free'd and proper DISCONNECTING
5907 flags, etc. can be set to avoid sending data to connection that
5908 is not valid anymore.
5910 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5911 the connection. After that it sets SILC_SET_DISCONNECTED.
5912 It is, however, possible that the socket data is not still freed.
5913 The silc_server_packet_process now checks that data is not
5914 read or written to connection that is DISCONNECTED. The socket
5915 get's freed when the reference counter hits zero.
5917 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Changed the client operation API: channel_message operation's
5920 `sender' is now the client entry of the sender, not the nickname
5921 and the `channel' is the channel entry, not the channel name.
5923 In the private_message operation the `sender' is now also the
5924 client entry of the sender not the nickname.
5926 Affected file is lib/silcclient/ops.h and all applications
5927 using the client operations.
5929 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Moved the calling of ops->connect() from connect_to_server_final
5932 into receive_new_id functin since that is the point when the
5933 client is actually allowed to send traffic to network. The
5934 affected file is lib/silcclient/client.c.
5936 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5939 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5940 (if needs broadcasting) instead of broadcasting the packets one
5941 by one which would make a burst in the network traffic.
5943 * Added `broadcast' argument to the functions in silcd/server.[ch]
5944 silc_server_create_new_channel[_with_id] to indicate whether
5945 to send New Channel packet to primary router.
5947 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Added new function into the silcd/server.[ch] files:
5950 silc_server_create_new_channel_with_id to create new channel with
5951 already existing Channel ID.
5953 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5954 lib/silccore/silcpacket.h. This packet is used t send list of
5955 Set Mode payloads inside one packet. Server uses this to set
5956 the modes for the channels and clients on those channels, that it
5957 announced to the router when it connected to it. The protocol
5958 specification has been updated accordingly.
5960 * The silc_server_new_channel did not handle the packet coming
5961 from normal server as it normally does not send that. However,
5962 when it announces its channels it does send it. Implemented
5963 the support for that.
5965 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5966 into the file lib/silccore/id.h.
5968 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5970 * Fixed memory leaks in the functions silc_idlist_del_client,
5971 silc_idlist_del_channel and silc_idlist_del_server in the file
5972 silcd/idlist.c. All of those leaked like a sieve.
5974 * Fixed some small memory leaks in the client's function
5975 silc_client_notify_by_server.
5977 * Added functions into silcd/server.c: silc_server_announce_clients,
5978 silc_server_announce_channels and silc_server_announce_server.
5979 These functions are used by normal and router server to announce
5980 to its primary router about clients, channels and servers (when
5981 router) that we own. This is done after we've connected to the
5984 These functions effectively implements the following packet types:
5985 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5986 and SILC_PACKET_NEW_ID_LIST.
5988 * Added new functions into the silcd/packet_receive.[ch]:
5989 silc_server_new_id_list, silc_server_new_channel_list and
5990 silc_server_new_channel_user_list to handle the incoming
5991 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5993 * Added support of changing Channel ID in the function
5994 silc_server_replace_id. If the server that announces a channel
5995 to the router already exists in the router (with same name but
5996 with different Channel ID), router is responsible to send
5997 Replace ID packet to the server and force the server to change
5998 the Channel ID to the one router has.
6000 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6001 client that the Channel ID has been changed by the router. The
6002 normal server sends this to the client. Client must start using
6003 the new Channel ID as the channel's ID.
6005 Implemented handling of this new type into lib/silcclient/client.c
6006 into the function silc_client_notify_by_server.
6008 * Added new function silc_idlist_replace_channel_id into the files
6009 silcd/idlist.[ch] to replace the Channel ID.
6011 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Call silc_server_command_identify_check always when processing
6014 the IDENTIFY command in silcd/command.c
6016 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6018 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6019 send keepalive packets. The packet can be sent by clients,
6020 servers and routers.
6022 Added function silc_socket_set_heartbeat into the file
6023 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6024 If not set, the heartbeat is not performed. The actual
6025 heartbeat is implemented in the low level socket connection
6026 library. However, application is responsible of actually
6029 Added silc_server_send_heartbeat to send the actual heartbeat
6030 packet into silcd/packet_send.[ch]. Server now performs
6031 keepalive with all connections.
6033 * Added silc_task_get_first function into lib/silcutil/silctask.c
6034 to return the timeout task with shortest timeout. There was a bug
6035 in task unregistration that caused problems. TODO has been
6036 updated to include that task system must be rewritten.
6038 * The client library will now resolve the client information when
6039 receiving JOIN notify from server for client that we know but
6040 have incomplete information.
6042 * Rewrote parts of silc_server_remove_from_channels and
6043 silc_server_remove_from_one_channel as they did not remove the
6044 channel in some circumstances even though they should've.
6046 * Encryption problem encountered in server:
6048 The LEAVE command used to send the Channel Key packet to the
6049 router immediately after generating it. However, the code
6050 had earlier sent Remove Channel user packet but not immediately,
6051 ie. it was put to queue. The order of packets in the router
6052 was that Channel Key packet was first and Remove Channel User
6053 packet was second, even though they were encrypted in the
6054 reverse order. For this reason, MAC check failed. Now, this
6055 is fixed by not sending the Channel Key packet immediately but
6056 putting it to queue. However, this is more fundamental problem:
6057 packets that are in queue should actually not be encrypted
6058 because packets that are sent immediately gets encrypted
6059 actually with wrong IV (and thus MAC check fails). So, packets
6060 that are in queue should be encrypted when they are sent to
6061 the wire and not when they put to the queue.
6063 However, the problem is that the current system has not been
6064 designed to work that way. Instead, the packet is encrypted
6065 as soon as possible and left to the queue. The queue is then
6066 just purged into wire. There won't be any fixes for this
6067 any time soon. So, the current semantic for packet sending
6070 o If you send packet to remote host and do not force the send
6071 (the packet will be in queue) then all subsequent packets to the
6072 same remote host must also be put to the queue. Only after the
6073 queue has been purged is it safe again to force the packet
6076 o If you send all packets immediately then it safe to send
6077 any of subsequent packets through the queue, however, after
6078 the first packet is put to queue then any subsequent packets
6079 must also be put to the queue.
6081 Follow these rules and everything works fine.
6083 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Added new function silc_server_remove_clients_by_server to
6086 remove all client entries from ID list when the server connection
6087 is lost. In this case it is also important to invalidate all
6088 client entires as they hold the invalid server entry. This
6089 fixes fatal bug when server has lost connection and will reconnect
6092 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Made some sanity checks to silc_server_daemonise like to check
6095 whether the requested user and group actually exists.
6097 * Added sanity check to SKE's silc_ske_responder_finish to check
6098 that the public and private key actually is valid.
6100 * Invalidate the client's nickname when receiving Replace ID
6101 packet and the Client ID is being replaced. This means that the
6102 server will query the nickname if someone needs it (client)
6105 * Sort the ID Cache in client library when the ID Cache data
6106 has changed (needs sorting).
6108 * Do not allow for SILC client to create several connections to
6109 several servers. The client does not support windows right now
6110 and generating multiple connections causes weird behaviour.
6112 Irssi-silc client does support windows and can handle several
6113 connections without problems, see: www.irssi.org and SILC plugin.
6115 * Fixed some places where client was added to the IDList. The
6116 rule of thumb is following (in order to get everything right):
6117 If the client is directly connected local client then the
6118 `connection' argument must be set and `router' argument must be
6119 NULL to silc_idlist_add_client function. If the client is not
6120 directly connected client then the `router' argument must
6121 bet set and the `connection' argument must be NULL to the
6122 silc_idlist_add_client function.
6124 * The funtion silc_server_packet_send_local_channel actually did
6125 not check whether the client was locally connected or not. It
6126 does that now. Fixed a bug related to LEAVE command.
6128 * Fixed Remove Channel User payload parsing bug in server's
6129 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6131 * The server's silc_server_save_channel_key now checks also the
6132 global ID list for the channel as it might not be in the local
6133 list. Fixed a bug related to LEAVE command.
6135 * Is this the end of the [<unknown>] buglet that has been lurking
6136 around for a long time? A little for loop fix in server's
6137 silc_server_command_whois_parse that is used by both IDENTIFY
6138 and WHOIS command. At least, this was a clear bug and a cause
6139 of one type of [<unknown>] buglet.
6141 * WHOIS and IDENTIFY commands call the function
6142 silc_server_command_[whois/identify]_check function even if
6143 we are not router server.
6145 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Added --with-gmp configuration option. If set the GMP
6148 is always compiled in the SILC source tree. If not set then
6149 it is checked whether the system has the GMP3 installed. If
6150 it has then the GMP won't be compiled (the system's headers
6151 and library is used), if it doesn't have it then the GMP is
6152 compiled in the SILC source tree.
6154 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6156 * Changed RSA private exponent generation to what PKCS #1
6157 suggests. We try to find the smallest possible d by doing
6158 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6159 not security fix but optimization.
6161 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6163 * Added new config entry [Identity] to fork the server and run
6164 it as specific user and group. A patch from Bostik.
6166 * Imported Dotconf configuration library into lib/dotconf.
6167 This will be used to create the SILC configuration files later.
6168 It will appear in the distsribution after this commit.
6170 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * A big code auditing weekend happening. Auditing code for
6173 obvious mistakes, bugs and errors. Also, removing any code
6176 Removed files for being obsolete:
6178 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6179 inline in the file lib/silcutil/silcbuffer.h)
6181 o lib/silcutil/silcbufutil.c (the header has inline versions)
6183 Changed code to fix possible error conditions:
6185 o The buffer formatting routines now check that the destination
6186 buffer really has enough space to add the data. This applies for
6187 both buffer formatting and unformatting
6188 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6189 unformatting was changed to accomodate following rules:
6190 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6191 sent to the function while XXX_*STRING will not allocate or copy
6192 the data into the buffer. Instead it sets the pointer from the
6193 buffer into the pointer sent as argument (XXX_*STRING used to
6194 require that the pointer must be allocated already). This change
6195 makes this whole thing a bit more consistent and more optimized
6196 (note that the data returned in the unformatting with XXX_*STRING
6197 must not be freed now). The routines return now -1 on error.
6199 o Tried to find all code that use buffer_format and buffer_unformat
6200 and added return value checking to prevent formatting and
6201 especially unformatting errors and possible subsequent fatal
6204 o Changed ske->x and ske->KEY to mallocated pointers in
6205 lib/silcske/silcske.h. Fixed possible data and memory leak.
6207 o Added return value checking to all *_parse* functions. Fixed
6208 many memory leaks as well.
6210 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6211 so that buffer overflows would not happen. All code now also
6212 checks the return value as it can fail.
6214 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6216 * Added reconnection support to server if the normal server looses
6217 its connection to the router (for example if router is rebooted).
6218 The server performs normal reconnection strategy implemented
6219 to the server. Affected file silcd/server.c.
6221 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6223 * Added new packet type SILC_PACKET_SET_MODE that is used to
6224 distribute the information about changed modes (for clients,
6225 channels and clients channel modes) to all routers in the
6226 network. Updated the protocol specification accordingly.
6228 Added functions into silcd/packet_send.c and
6229 silcd/packet_receive.c: silc_server_send_set_mode,
6230 silc_server_set_mode.
6232 Added new files silcmode.[ch] into lib/silccore that implements
6233 the encoding and decoding of Set Mode Payload. Added new type
6234 SilcSetModePayload. Moved the definitions of different modes
6235 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6237 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * Oops, a little mistake in server's connection authentication
6240 protocol. The protocol is not ended with FAILURE but with
6241 SUCCESS if the authentication is Ok. :) Affected file is
6244 * Implemented NICK_CHANGE notify handling in server in the file
6245 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6246 the local clients on the channel. After the changing nickname
6247 in router environment snhould work and the [<unknown>] nickname
6248 should appear no more.
6250 The silc_server_replace_id function that receives the Replace ID
6251 payload now sends the NICK_CHANGE notify type also in the file
6252 silcd/packet_receive.c
6254 * Changed WHOIS and IDENTIFY command to support the maximum amount
6255 of arguments defined in protocol specs (3328 arguments). This
6256 fixed a bug that caused problems when there were more than three
6259 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Added extra parameter, command identifier, to the
6262 silc_client_send_command so that explicit command identifier
6265 Changed that ID list routines uses specific command identifier
6266 when sending WHOIS/IDENTIFY requests to the server so that they
6267 can be identified when the reply comes back.
6269 Affected files lib/silcclient/command.[ch],
6270 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6272 * Added `sender' argument to silc_server_packet_send_to_channel
6273 to indicaet the sender who originally sent the packet to us
6274 that we are now re-sending. Ignored if NULL. Affected file
6275 silcd/packet_send.[ch].
6277 * Added some server statistics support in silcd/server_internal.h
6278 SilcServerStatistics structure and around the server code. Also
6279 send some nice statistics information when client is connecting
6282 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6284 * Fixed channel ID decoding in server's JOIN command reply in
6285 silcd/command_reply.c
6287 * Fixed braodcasting of replace ID payload to not to send it if
6288 we are standalone server in silcd/packet_receive.c.
6290 * Fixed all channel message sending routines to not to send
6291 packets to clients that has router set, since they are routed
6292 separately in the same function earlier. Affects file
6293 silcd/packet_send.c and all channel packet sending functions.
6295 * In USERS reply, res_argv[i] are not allocated, the table
6296 is allocated. Thus changed that free the table, not its
6299 * In server's whois_check and identify_check if the client is
6300 locally connected do not send any WHOIS commands - they are not
6303 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6305 * Fixed some minor bugs in client when sending WHOIS command. The
6306 arguments was in wrong order.
6308 * Removed statis function add_to_channel from server in
6309 silcd/command.c that was previously used with the joining but
6312 * Tested USERS command in router environment successfully with two
6313 routers, two servers and two clients.
6315 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6317 * Reorganized the USERS command and command reply in client library
6318 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6319 When the command is given by user we register a pending command
6320 callback that will reprocess the command after the reply has been
6321 received from the server. When reprocessing the packet we then
6322 display the information. Thus, the USERS information is displayed
6323 now in the command callback instead of in the command reply
6324 callback. The processing of the command is same as previously
6325 when server has sent the command reply in the JOINing process.
6327 * Added to USERS command in silcd/command_reply.c to join the client,
6328 we didn't use to know about, to the channel after we've created
6329 a client entry for it. Also, for clienet we did know already still
6330 check whether it is on the channel or not and add it if not.
6332 * Removed silc_server_command_join_notify as the function and its
6335 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Changed the client's pending command handling to the same as the
6338 server's pending command handling. It is also now possible to
6339 execute command reply functions from other command reply
6340 function as the function callbacks for commands and command
6341 replies are one and same. The pending commands are not static
6342 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6343 in client connection context. Thus, pending commands are server
6344 connection specific as it is convenient.
6346 Changed the function silc_client_command_pending and
6347 silc_client_command_pending_del and added new function
6348 silc_client_command_pending_check. Removed the
6349 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6352 * Added cmd_ident, current command identifier, to the client
6353 connection context in lib/silcclient/client.h to keep track on
6354 command identifiers used in command sending. Client's command reply
6355 function handling now supports the mandatory command identifiers.
6357 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6358 funtions in client to fully support pending command callbacks.
6360 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6361 as one of the arguments to the application in the command reply
6364 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6365 before first releasing SILC but came back. Now it is removed again
6366 and should come back nomore. The FORWARDED flag was used only
6367 by the JOINing procedure by forwarding the command packet to router.
6368 Now, the JOINing procedure has been changed to more generic (due
6369 to various router environment issues) and FORWARDED is not needed
6370 anymore for anything. The protocol specification is yet to be
6373 Now, removed silc_server_packet_forward from server and the flag
6374 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6376 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6378 * Renamed NAMES command to USERS command. The NAMES was named that
6379 due to historical reasons. Now it is renamed. Also, rewrote
6380 parts of the USERS command. The nickname list is not sent anymore
6381 by the server. Only Client ID and mode lists are sent in the USERS
6382 command. Changed this also to the protocol specification.
6384 The client now resolves the names and stuff after it receives
6385 the USERS list from the server when joining to the channel.
6387 * WHOIS and IDENTIFY commands has been changed to support multiple
6388 Client ID's per command. One can now search for multiple users
6389 in the network by sending only one WHOIS or IDENTIFY command.
6390 Changed the code and the protocol specifications.
6392 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6393 uses silc_server_command_whois_parse to parse the request. */
6395 * If normal server, do not parse the WHOIS and IDENTIFY requests
6396 before sending it to the router. Saves some time.
6398 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Fixed JOIN command on client library. Wrong number of arguments
6401 used to crash the client.
6403 * Added silc_server_channel_has_global function to check whether
6404 channel has global users or not.
6406 * Added silc_server_channel_has_local function to check whether channel
6407 has locally connected clients on the channel.
6409 * The silc_server_remove_from_one_channel now checks whether the
6410 channel has global users or not after given client was removed from
6411 the channel. It also checks whether the channel has local clients
6412 on the channel anymore. If it does not have then the channel entry
6413 is removed as it is not needed anymore.
6415 * The silc_server_notify now checks on JOIN notify whether the joining
6416 client is one of locally connected or global. If it is global then
6417 the channel has now global users on the channel and that is marked
6418 to the channel entry. Also, it now saves the global client to
6419 global list who is joining and JOINs it to the channel. This is
6420 for normal server, that is.
6422 Changed silc_server_send_notify_on_channel,
6423 silc_server_packet_relay_to_channel and
6424 silc_server_packet_send_to_channel check if we are normal server
6425 and client has router set (ie. global client) do not send the
6426 message to that client, as it is already routed to our router.
6428 * Implemented LEAVE notify type handling in silc_server_notify
6431 * Tested LEAVE command in router environment successfully. Tested
6432 with two routers, two servers and two clients.
6436 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6438 * Implemented SIGNOFF notify type handling in silc_server_notify
6441 * silc_server_remove_id now removes the client entry from all channels
6442 it has joined and thusly sends SIGNOFF notify type.
6444 * Rewrote the NAMES list generation in server by removing two excess
6445 loops. The lists are created now inside one loop.
6447 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6449 * silc_server_remove_channel_user checks now also global list
6450 for channel and client.
6452 * silc_server_new_channel_user checks now both local and global
6453 list for channel and client. Fixed a bug in client id decoding.
6454 Used to decode wrong buffer.
6456 * silc_server_channel_message checks now both local and global
6457 list for channel entry.
6459 * Tested channel joining (hence JOIN) in router environment
6460 successfully. Tested with two routers, two servers and two
6463 * Tested channel message sending in router environment successfully.
6465 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6467 * Added silc_server_save_channel_key into server.[ch] to save the
6468 received channel key in Channel Key payload processing. It is
6469 also used in JOIN command reply handling.
6471 Equivalent function silc_client_save_channel_key added into
6472 client.[ch] into client library.
6474 * Changed JOIN command reply to send information whether the channel
6475 was created or not (is existing already) and the channel key
6476 payload. Changed protocol specs accordingly.
6478 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6479 the request was sent by ID and not by nickname. Crashed on
6482 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6485 now correctly save the received data.
6487 * silc_server_free_sock_user_data now notifies routers in the
6488 network about entities leaving the network.
6490 At the same time implemented functions silc_server_remove_id
6491 and silc_server_send_remove_id to receive and send REMOVE_ID
6492 packets. The packet is used to notify routers in the network
6493 about leaving entities. The ID removed will become invalid in
6496 * Added function silc_idlist_del_server into server. Removes and
6497 free's server entry from ID list.
6499 * silc_server_private_message function now checks, if we are router,
6500 that the destination ID really is valid ID, naturally.
6502 * In router when NEW_ID packet is received (for new client) the
6503 hash of the Client ID is saved in the ID Cache but the
6504 client->nickname is set to NULL, instead of putting the hash
6507 IDENTIFY command now also checks that client->nickname must be
6508 valid. If it is not if will request the data from the server who
6509 owns the client. Added new function
6510 silc_server_command_identify_check.
6512 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6513 to set the command to already allocated Command Payload.
6515 * Tested private message sending in router environment with two
6516 routers, two servers and two clients. Fixed minor bugs and now
6519 * Fixed segfault from client's NAMES command. Used to crash if
6522 * Forwarded packets must not be routed even if it is not destined
6523 to the receiver. Changed server code comply with this.
6525 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6527 * Added `require_reverse_mapping' boolean value to ServerParams
6528 structure. If TRUE (not default) the server will require that
6529 the connecting host has fully qualified domain name.
6531 If the reverse mapping is not required and hostname could not be
6532 found the IP address is used as hostname.
6534 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Implemented version string checking to both client and server.
6537 The check is incomplete currently due to the abnormal version
6538 strings used in development version of SILC.
6540 * Changed all command functions in server to use the new
6543 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Changed char *data to unsigned char *data in ID Cache system to
6546 support binary data as ID Cache data. Changed code to support
6547 binary data in lib/silccore/idcache.c.
6549 * Renamed silc_server_packet_relay_command_reply to
6550 silc_server_command_reply as it is normal packet receiving
6551 function. Rewrote the function to accept command replys for
6552 servers and not only for clients.
6554 * Mark remote router always as registered server if we are connecting
6555 to it. Otherwise, commands sent by the router to us are ignored.
6557 * All ID List find routines now returns the ID Cache Entry pointer
6558 as well if requested.
6560 * WHOIS command works now in router environment, tested with two
6561 routers, two servers and two clients.
6563 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6564 in router environment (as it is almost equivalent to WHOIS) but
6565 hasn't been tested thoroughly. Added new functions:
6567 silc_server_command_identify_parse
6568 silc_server_command_identify_send_reply
6569 silc_server_command_identify_from_client
6570 silc_server_command_identify_from_server
6572 * Disabled route cache adding because adding two different ID's with
6573 same IP replaces the old cache entry thus giving wrong route.
6574 The entry->router->connection is always the fastest route anyway
6575 so route cache may not be needed. Of course, new routes maybe
6576 established after receiving the ID when the entry->router->connection
6577 might not be anymore the most optimal.
6579 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6581 * Add route cache for received ID for fast routing.
6583 * Added silc_server_packet_route to route received packet on router
6584 that is not destined to us.
6586 * Renamed silc_server_get_route to silc_server_route_get.
6588 * Added id_string and id_string_len fields into SilcServer to
6589 include encoded ServerID for fast comparing without excess
6590 encoding of the ID's.
6592 * Cleaned up WHOIS command on server side. Added following static
6595 silc_server_command_whois_parse
6596 silc_server_command_whois_check
6597 silc_server_command_whois_send_reply
6598 silc_server_command_whois_from_client
6599 silc_server_command_whois_from_server
6601 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6602 arguments in command replies. All command functions should be
6603 updated to use this macro.
6605 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6607 * Minor typo fixes on command reply handling on server.
6609 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6611 * Added silc_server_command_add_to_channel internal routine to add
6612 the client to the channel after router has created the channel and
6613 sent command reply to the server.
6615 * Added generic silc_server_send_command to send any command from
6618 * Use static buffer with ID rendering instead of duplicating data.
6620 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6622 * Fixed a channel user mode bug when joining to a channel server gave
6623 everybody channel founder rights, oops.
6625 * We mark ourselves as the router of the incoming server connection
6626 if we are router ourselves. This way we can check in some packet
6627 sending functions whether it is locally connected server. For
6628 incoming router connections we put NULL.
6630 * For router sending packets locally means now always sending the
6631 packet cell wide; to local clients and local servers. For normal
6632 server sending packet locally means sending it to only local
6635 * Fixed the JOIN command to really work in router environment. If the
6636 channel is created it is always created by the router. Router is
6637 also responsible of making the initial joining to the channel,
6638 sending JOIN notify to the sending server and distributing
6639 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6640 does not exist server doesn't do anything else but forward the
6641 command to the router which performs everything.
6643 * Added silc_server_send_channel_key function to send the Channel Key
6646 * Added silc_server_create_channel_key to create new channel key. The
6647 channel key is now re-generated everytime someone joins or leaves
6648 a channel, as protocol dictates. Note: channel->key_len is the
6651 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6654 packet_receive.[ch] to separate packet sending and receiving
6655 routines. The server.[ch] now includes everything else including
6656 actual packet processing (writing and reading data) and other
6659 Renamed silc_server_private_message_send_internal to
6660 silc_server_send_private_message. The routine is still though
6661 used only to relay private messages as server does not send
6662 private messages itself.
6664 Renamed silc_server_new_channel to silc_server_create_new_channel
6665 and added new function sicl_server_new_channel that handles the
6666 incoming New Channel packet. Added also new sending function
6667 silc_server_send_new_channel to send New Channel Payload.
6669 * Added new function silc_server_notify to process incoming notify
6670 packet to the server/router. Server may then relay the notify
6671 to clients if needed.
6673 * Added new function silc_server_new_channel_user to process incoming
6674 New Channel User packet. Router will redistribute the packet and
6675 send JOIN notify to its local clients and locally connected servers
6676 if needed. Normal server will send JOIN notify to its local client
6677 on same channel when received this packet. Added also corresponding
6678 sending function silc_server_send_new_channel_user to sent the
6681 * Added boolean route argument to send_notif_to_channel and
6682 packet_send_to_channel functions to attempt to route the packet
6683 if it is TRUE and send only locally if it is FALSE.
6685 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6687 * silc_server_replace_id now broadcasts the received replace ID
6688 packet if it is not broadcast packet already. The router must
6689 broadcast to inform other routers about changed ID.
6691 * Added backpointer to server's router into SilcServer context in
6692 silcd/server_internal.h.
6694 * Fixed silc_server_packet_broadcast to send correct broadcast
6697 * The channel key is now distributed to the local client as soon
6698 as it is received from the router (in router environment) so that
6699 no other packet may be sent for the channel until client has
6702 * silc_server_remove_channel_user now broadcasts the received
6703 Remove Channel User packet if it is not broadcast packet already.
6704 The router must broadcast to inform other routers about removed
6707 * Added users field into SilcPacketContext that is a reference count
6708 of the context. One can increase the reference count by calling
6709 silc_packet_context_dup which is now changed to just increase the
6710 reference count instead of duplicating the data. The reference
6711 count is decresed by calling silc_packet_context_free that will
6712 free the data after the reference count hits zero.
6714 For now on the packet context and everything allocated into it
6715 (including the raw packet from network) must be freed by calling
6716 the new silc_packet_context_free function. Added also new function
6717 silc_packet_context_alloc that must be used now to allocate the
6718 context. This also means that if a routine is asynchronous from
6719 silc_[client/server]_packet_parse_type the packet context must
6720 be duplicated by calling silc_packet_context_dup. Otherwise it
6721 gets free'd after silc_[client/server]_packet_parse_type returns.
6722 Also, one must remember that if packet is duplicated then its
6723 reference count must be decresed by calling the free function as
6724 many times as it was duplicated.
6726 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6727 from both client and server.
6729 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6731 * Made joining to a channel working in router environment.
6733 * Cleaned up JOIN command on server side and create function
6734 silc_server_command_join_channel internal routine to make the
6737 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6739 * Changed silc_command_pending list to SilcDList. Also, added
6740 `ident' field to SilcServerCommandPending structure to identify
6741 the reply and to call correct callback.
6743 Added silc_server_command_pending_check function to replace the
6744 corresnponding macro. The silc_command_pending list is not
6747 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6748 to set identifier to previously allocated Command Payload. It
6749 is used to set identifier for command when resending Command
6752 * Added silc_command_payload_encode_payload to encode Command
6753 Payload buffer from SilcCommandPayload structure.
6755 * Added silc_argument_payload_encode_payload to encode Argument
6756 payload buffer from SilcArgumentPayload structure.
6758 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6760 * Changed WHOIS command to support router connection on server side.
6761 The whois request is always sent to router unless the server is
6762 standalone server. After server has received the reply from the
6763 router will it send the reply to the client.
6765 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6766 broadcast received broadcast packet. The function is used only
6767 by router. The broadcast packet is always sent to the router's
6770 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6771 render given ID to printable string, for log files for example.
6773 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6775 * Made basic router to router connections working. At least they
6776 can now connect to each other but nothing really works the way
6777 they are supposed - yet.
6779 * Added new initiator token to RouterConnection configuration
6780 file in silcd/serverconfig.[ch]. It is used to tell whether we
6781 are the initiator to the remote router or whether we'll expect
6782 the other end to connect.
6784 * Moved registering of listener task to silc_server_init, hence
6785 the server starts listenning as soon as it is run, even if it
6786 does not have connections to other routers. Let's see how well
6789 * Changed default connection retry timeouts for more suitable in
6792 * Removed cipher and such arguments from silc_idlist_add_client
6793 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6794 Added new function silc_idlist_add_data to add the keys and stuff
6797 * Added SilcIDListData structure and added it to SilcClientEntry
6798 and SilcServerEntry as their first field in the structure. This
6799 way we can explicitly cast the ID entries to the SilcIDListData
6800 structure and get common data for the entries. In past, we had
6801 to first check what type of connection it is and then cast it to
6802 correct ID entry type. Now, we can directly cast the opaque
6803 pointer to the SilcIDListData (no matter what ID entry it actually
6804 is) and get the data needed.
6806 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6809 in some circumstances even if threre were timeout tasks, though not
6810 IO tasks, but tasks anyway. Now fixed.
6812 * Defined SilcServerConnection structure to hold connection specific
6813 stuff about directly connected servers and routers. The definition
6814 is currently in silcd/server_internal.h. I thought about having
6815 a bit more important role fro this struct but for now it is used
6816 only when connecting to other server (or router actually).
6818 * Added connecting retry support in server when connecting to
6819 router(s). The retry feature implement exponential backoff
6820 algorithm. Also, added SilcServerParams structure to hold default
6821 parameters for server. For now, it include these retry settings
6822 and are hard coded. After server is moded to be as Silc Server
6823 Library this structure will be more important.
6825 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6827 * Changed client librarys channel->clients table to SilcList and
6828 changed code accordingly.
6830 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * Changed client's channel table to SilcList and changed code
6833 accordingly. Also changed SilcChannelClientEntry to include back-
6834 pointer to the channel so that client entry can use that structure
6835 as list as well and we have fast cross-reference to the channel.
6836 This change dramatically decreased the complexity of channel
6837 handling with client entry and vice versa (removed one extra
6838 loop when searching for channel entry from many functions).
6840 * Changed server->sim from table to SilcDList and changed code
6843 * NAMES command can now be used from user interface. It will show
6844 the user list on the channel, neatly.
6846 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6847 Code now saves realname of the user if it becomes available.
6849 * Renamed configure.in to configure.in.pre and made ./prepare
6850 script to automatically add correct version string to
6851 configure.in which it creates from configure.in.pre.
6853 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6855 * NAMES command reply now shows users mode with the nickname when
6858 * Moved silc_client_ch[u]mode[_char] functions from
6859 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6860 place sucks, they are utility functions and should be in some
6863 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6865 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6868 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6872 * Added TRQ (efficient deque and list library) into lib/trq. This is
6873 a very good list library that is currently used in the SILC. Defined
6874 SilcList API over the library because I didn't like the API very
6875 much. See lib/trq/silclist.h for the API and examples of how to
6876 use the API. Fixed various places in the code to use the new
6877 SilcList API. The SilcList is meant for lists that has a structure
6878 already defined as a list. It is not suitable to add just some
6879 context to the list (in TRQ, the context is the list actually).
6881 So, I defined SilcDList that can be used for the purpose where
6882 predefined list structure does not exit. This can be used as
6883 such list. Now some context just can be added to the SilcDList.
6884 Currently this list is not used in the SILC just yet, though there
6885 are a lot places where this can replace dynamically allocated
6886 tables and I will fix these places, later, to use SilcDList.
6887 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6888 and use TRQ internally).
6890 Also fixed some annoying warning messages that the original TRQ
6891 code generated. Also minor changes to TRQ's Makefile.in.
6893 * Added support for querying by Client ID to both WHOIS and
6894 IDENTIFY commands into server, as required by the protocol.
6896 * Removed method function pointers from SilcBuffer structure. They
6897 weren't used to anything and just increased the context size for
6898 no good reason. This change also made silc_buffer_alloc and
6899 silc_buffer_free functions inline functions.
6901 * Disabled command flooding detection support until it's fixed so
6902 that it accepts commands in but does not execute them more than once
6905 * Added silc_net_localhost(), to return local hostname, into
6906 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6907 that must be initialized before calling silc_client_init.
6909 * Added new function: silc_server_send_notify_on_channels to send
6910 notify messages to all channels client has joined. It is assured
6911 that the message is sent only once per client.
6913 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6914 lib/silcutil/silcutil.[ch] as silc_format function. The new
6915 function is generic and is used by server as well, not only by
6916 the logging routines.
6918 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6919 the provided version string was not acceptable. Added new function:
6920 silc_ske_check_version into lib/silcske/silcske.h. The function
6921 must be implemented by the application (client or server) and it
6922 does not reside in the SKE library. The function checks the version
6923 string remote end sent.
6925 * Added back pointers (to opaque context and to SilcSocketConnection)
6926 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6928 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6929 duplicate packet context structure.
6931 * Changed `notify' client operation to send same arguments as client
6932 receives from server except for ID's. ID's are mapped to correct
6933 ID entry and that is returned. Also, if channel entry is not sent
6934 by server but the notify is for channel the channel entry is sent
6935 to application (otherwise application doesn't know that it is for
6936 channel (library gets it from packet's Destination ID)).
6938 * Added silc_client_remove_from_channels into client library to
6939 remove a client from all channels it has joined to. Used when
6940 received SIGNOFF notify from server. Added also new function
6941 silc_client_replace_from_channels to replace old ID entry with
6942 new ID entry on all channels. Used when received NICK_CHANGE
6945 * Fixed ID Cache list handling in silc_idlist_get_client in
6946 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6947 to get (or query) client by ID.
6949 * Updated TODO list.
6951 * Added connection authentication status message defined by the
6952 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6953 support for these into the code in client and server side.
6955 * Added generic function silc_client_send_command to send any command
6956 with variable argument list. Application should use this function
6957 to send commands if the command functions provided by the library
6958 does not suite for the application's user interface needs.
6960 * Added new `failure' client operation. Application is notified about
6961 received failure packet if client is executing a protocol. In this
6962 case the protocol's execution has failed.
6964 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6965 is required by the protocol.
6967 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6968 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6971 * Added status flag to SilcSKE object to indicate realtime status
6972 of the SKE protocol.
6974 * Application receives now exactly same command reply arguments as
6975 the library receives from server. However, if ID is received the
6976 corresponding ID entry is returned to the application (eg. Client
6977 ID is mapped to correct SilcClientEntry entry and that is returned).
6978 Changed command_reply client operation due to this change.
6980 * Changed all ID's in commands and in command replys as ID Payloads.
6981 Change affected both client and server side codes.
6983 All ID's sent in SILC network (with execption of ID's in SILC
6984 Packet header) are sent in ID Payload to support variable length
6987 * Server now notifies nick changes and notifies all clients on
6988 the channels about the new nickname (about the new Client ID,
6991 * Implemented CMODE command to change channel modes. Supports all
6992 channel modes defined by the protocol specs except ban and invite
6993 lists. (Also, private channel key mode is supported but support for
6994 setting private channel key in client is missing, thus, this mode
6995 has no effect on client side (except that server requires that the
6996 client uses private channel key and normal channel traffic does not
6999 Also, invite mode works per se, but INVITE command does not work
7000 yet correctly, so you can set channel as invite only channel but
7001 inviting clients to the channel does not work (it is yet to be
7002 thought what's the best way to do it).
7004 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7005 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7006 Implemented CUMODE command to change user's mode on the channel.
7007 Supports all modes defined by the protocol specs.
7009 * Added NAMES command reply to return users modes on the channel.
7011 * Removed unnecessary and slow ciphers from lib/silccrypt.
7013 * Set SO_KEEPALIVE option to connection sockets by default.
7015 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7017 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7018 redefined the Notify Payload into protocol specs.
7020 * Added silc_id_payload_parse_id to get ID directly from raw
7023 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7025 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7026 accept searching by Client ID as well.
7028 * Added support for LEAVE and SIGNOFF notify types in client library.
7030 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7031 to parse ID Payload from raw data.
7033 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7035 * Added flags parameter into silc_ske_assemble_security_properties
7036 function in lib/silcske/silcske.[ch].
7038 * Changed notify client operation to fit better for notify messages
7039 sent by server. The notify payload received from server is now
7040 passed to the application (after parsing it to SilcNotifyPayload).
7041 It is application's responsibility to retrieve the arguments
7042 from the payload and show the message the way it wants. The message
7043 sent by server is implementation specific.
7045 * Changed public keys to comply with the protocol specification.
7046 Old public keys are not supported anymore and are not compatible.
7048 * Removed nickname from Channel Payload as the latest draft removed
7049 it. The client must resolve the nickname from the NAMES command
7050 reply received when it joined the channel.
7052 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7054 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7056 * Fixed some errors in protocol specification drafts.
7058 * Created lib/silccore/silcnotify.c to implement Notify Payload
7059 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7060 generic payloads described by protocol specifications. The file
7061 includes implementations for ID Payload and Argument Payload.
7063 * Changed Command Payload implementation to use the new Argument
7064 Payload. Changed command_xxxx_payload to command_payload_xxxx
7065 to comply with SILC coding conventions.
7067 * Added suppport for Argument Payload handling in Notify Payload
7068 implementation as protocol requires it. Added the new support
7069 into server and client lib as well.
7071 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7073 * Added support for multiple nicknames on same channel. [n] is
7074 added locally to the nickname if there are more than one same
7075 nicknames on the channel.
7077 * Server now sends all nicknames that matched WHOIS request.
7078 Client also shows the list received from server.
7080 * Added TOPIC command to client side. User can now set and show
7081 current topic on channel.
7083 * Added MOTD command to client and server. Also, server sends the
7084 motd when client connects to the server.
7086 * Changed version strings to comply ISO 8601.
7088 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7090 * Fixed protocol error handling in client library. It should now
7091 cope even if the SKE fails for some reason.
7093 * Made new protocol specification drafts for submitting to IETF.
7095 * Implemented TOPIC command to server in silcd/command.c.
7097 * Added two new notify types into lib/silccore/silcnotify.h:
7098 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7099 notify nickname change and topic setting/change on a channel.
7101 * API change of command_reply operation in client library. The
7102 application gets now the status type received from server as well.
7104 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7106 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7108 * Cras fixed and optimized the packet handling even further and
7109 it should work now. Minor change to the prototype of function
7110 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7112 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7114 * Added new function into lib/silcutil/silcschedule.[ch]:
7115 silc_schedule_with_fd to select() a specified fd. The function
7116 returns after timeout expires or data arrives or goes. The
7117 function is used by packet routines to wait that all data is
7118 received from network.
7120 * Fixed data reading from network in lib/silccore/silcpacket.c.
7121 The code now assures that all data is read from the fd and then
7122 continues packet processing. This was a bug fix since the code
7123 used to drop some data in some circumstances.
7125 * Added new function into lib/silcclient/client.[ch]:
7126 silc_client_start_key_exchange to start key exchange after
7127 connection has been established to server. The code internally
7128 now uses this funtion but its main purpose was to provide it
7129 for applications that perform their own connecting. After
7130 application has created a connection it merely calls this
7131 function to start the key exchange between client and server.
7132 The library takes care of everything else after that.
7134 Updated also lib/silcclient/README to explain the usage of
7137 * Do not send to application information that connection has
7138 been established. Application gets notified it by connect
7141 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7143 * Applied cras's patch to add silc_schedule_one function. The
7144 function runs scheduler once and returns.
7146 * Fixed the scheduler after cras messed it up. The timeout
7147 handling works now as it's supposed to work.
7149 * Added into lib/silccore/ silcnotify.h to include notify
7150 message types support. Changed silc_server_send_notify*
7151 functions, in server.[ch], to support those new notify types.
7152 Added the support for the notify types into client library,
7153 as well. Added new notify client operation into ops.h in
7156 * Changed silc_server_packet_send_to_channel to send normal
7157 packets instead of just channel message packets. The function
7158 is now used to send the notify packets to channels. It is not
7159 used to send channel message packets anymore, as server never
7162 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7163 va_arg()s as it seems to require it nowadays. I guess, if SILC
7164 is compiled with older va_arg() the new code should work anyway.
7166 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7168 * Splitted core library. Core library (lib/silccore) includes
7169 now only SILC protocol specific core (and common) components.
7170 Created new utility library (lib/silcutil) that includes more
7171 generic purpose stuff. The stuff for util library was taken
7172 from the old core library. This was minor and easy split.
7174 * Created SILC Client Library (lib/silcclient) that includes
7175 implementation of the SILC client without user interface. This
7176 was major move from silc/ directory. The code has been changed
7177 so that it is transparent towards the user interface. The
7178 silc/ directory includes now the same user interface as before
7179 and it uses the new client library. Read lib/silcclient/README.
7180 Basicly, the client library performs everything else related
7181 to SILC except user interface handling. Also, configuration
7182 files are considered to be part of user interface and library
7183 does not handle them.
7185 This change also changed a lot of structures, function naming etc.
7186 Most important change was that SilcClientWindow object was
7187 renamed to SilcClientConnection in the client library. Created
7188 also new file lib/silcclient/ops.h. Also added new files
7189 silc/local_command.[ch] and silc/client_ops.[ch].
7191 All these changes were made to make it easier for user interface
7192 designers to create what ever user interface for the SILC client
7195 It is also expected that the server will be moved to lib
7196 directory as well and SILC Server Library will be created;
7197 sometimes in the future.
7199 * Removed Local commands from lib/silccore/silccommand.h as
7200 they are application specific and new client library does not
7201 handle any of those anymore.
7203 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7204 old client implementation in silc/.
7206 * Added support for callback functions in SILC_LOG_* macros.
7207 Application can now set its own callbacks that will be called
7208 instead of using the default functions that will always print
7209 the debug messages to stderr (or stdout). Also, debugging can
7210 now be disabled by setting silc_debug to FALSE and re-enabled by
7211 setting it to TRUE. Note, that logging will still work even
7212 if debugging is disabled.
7214 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7215 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7216 silc_log_reset_debug_callbacks.
7218 * To enable debugging in silc client one must give now -d
7219 option on command line.
7221 * Changed silc_schedule_init to automatically allocate task queues
7222 if they are not allocated before calling it.
7224 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7226 * Added GMP 3.1 into math library.
7228 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7231 a channel in SILC network. The packet is used by servers and
7232 routers to notify other routers that user has left a channel.
7233 This little feature was missing until now. Added the feature
7234 to protocol specification as well.
7236 Added functions: silc_server_send_remove_channel_user and
7237 silc_server_remove_channel_user into server.[ch].
7239 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7240 lib/silccore/silcpacket.h. However, they are not implemented
7243 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7245 * Fixed joining to a channel and sending channel messages
7246 between server and router. The channel message sending should
7247 now work inside a cell.
7249 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7251 * Fixed the private message sending between server and router.
7252 The private message sending should now work inside a cell.
7254 * Added silc_server_replace_id into server.[ch] to replace
7255 existing ID in the SILC network.
7257 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7258 and silc_idlist_replace_server_id into idlist.[ch] in server.
7260 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7262 * Fixed the server to server connections. Server can again now
7263 connect to router. Router to router connections probably does
7266 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7268 * Added dynamic protocol registering support. Now protocols can
7269 registered and unregistered on the fly. Patch by cras.
7271 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7273 * Added lib/contrib directory to hold routines that some platforms
7274 don't have but are needed by SILC.
7276 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7277 into lin/contrib to provide getopt() and getopt_long() for
7278 those who don't have it.
7280 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7282 * Added AWAY command to client. When away message is set and
7283 client receives a private message packet the client automatically
7284 replies to the sender with the away message.
7286 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7287 bug seemed to be the cause of recent problems when compiling
7290 * Added version detection support to SKE protocol specification
7291 and added the new changes to the SKE implementation as well.
7292 There were other minor changes in the SKE protocol as well.
7294 Many changes in lib/silcske/silcske.[ch] and in
7295 lib/silcske/payload.[ch].
7297 * Added ^U functionality, clear input line. Patch from cras.
7299 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7301 * Mainly small bugfixes on core library. Fixed some debugging
7302 logging and buffer overflow in silclog.c.
7304 * Updated config.sub and config.guess on the distribution tree.
7306 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7308 * Added command lagging support in server. Client may execute
7309 commands now only once in two seconds.
7311 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7313 * Optimized packet reception. MAC computation and checking is now
7314 also more optimized. A lot previously duplicated code is now
7315 used as generic by both client and server.
7317 * Fixed key pair generation in clientutil.c
7319 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7321 * Added into lib/silccore/silcbufutil.[ch] new function;
7322 silc_buffer_realloc.
7324 * Moved generic packet sending/encryption functions to
7325 lib/silccore/silcpacket.[ch] from client and server. Some
7326 rewriting of the functions.
7328 * Moved all generic packet reception/decryption functions to
7329 lib/silccore/silcpacket.[ch] from client and server. The
7330 packet processing is now much cleaner in both client and server.
7331 These were major changes in both client and server.
7333 * Created many common functions in server to do packet sending.
7334 Previously code were duplicated a lot, this has been removed
7337 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7339 * Rewrote major parts of the ID cache system. Don't know
7340 whether it is better now or not but at least the API is more
7343 * Major rewrite on ID cache stuff on client because of the ID
7344 cache API changes. Added idlist.c to client.
7346 * Also major rewrite on ID cache stuff on server as well.
7347 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7348 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7349 in hand, instead they are all put into the ID cache system now.
7350 All server_idlist_* routines uses ID cache now instead of
7351 traversing its own lists (those lists does not exist anymore).
7352 SilcIDList though still exists. Also, SilcXXXEntry's are
7355 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7357 * Finally made the SKE implementation compliant to the protocol
7358 specification. All mp integers are now binary encoded as
7359 opposed being HEX encoded.
7361 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7364 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7365 functions: silc_[encode/decode]_pem. Also added function
7366 silc_encode_pem_file to PEM encode with newlines ('\n') for
7369 * SILC public keys are now encoded either PEM or binary. Same
7370 option is for private keys as well. By default private keys
7371 are binary encoded and public keys PEM encoded. Silly HEX
7372 encoding were removed.
7374 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7375 function to create fingerprints.
7377 * Fixed a bug in SHA1; does not change the original data anymore.
7379 * Partly implemented INFO command on client and server side.
7380 Fixed CLEAR command. Changes to SERVER command; show current
7381 server(s) when giving command without arguments. Added
7382 VERSION command to client.
7384 * Added check to server that unregistered connections cannot
7385 execute commands (unless it is specificly allowed).
7387 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7389 * Fixed screen refresh.
7391 * Fixed channel joining bug from client. On some circumstances
7392 client tried to join to a channel it had already joined.
7394 * Added public key verification process into client's protocol.c.
7395 The client now verifies the public key from user and saves
7396 it into ~./silc/serverkeys/ directory.
7398 Added into: clientutil.[ch]: silc_client_verify_server_key.
7400 * Changed SKE protocol's silc_ske_initiator_finish function
7401 to accept callback function that verifies the received public
7402 key. Removed old silc_ske_verify_public_key function.
7404 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7406 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7407 silc_pkcs_private_key[_data]_set.
7409 * Made the password and public authentication more cleaner in
7410 server's protocol.c.
7412 * Removed historic and obsolete protocol `channel_auth' from
7413 both client and server.
7415 * Removed wrong way of sending command status messages from
7416 server to client in server's command.c. The old way violated
7417 protocol specification.
7419 Changes to silccore/silccommand.[ch]: removed
7420 silc_command_encode_status_payload -> not needed anymore,
7421 changed silc_command_encode_payload_va to accept extra
7422 argument on variable argument list. The argument type must
7423 now be provided to the function. Also, added new function:
7424 silc_command_encode_reply_payload_va which is same as
7425 normal command_encode_payload_va except command status type
7426 is provided as extra argument.
7428 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7430 * Added ~./silc directory handling. The directory includes the
7431 public and private keys for the client.
7433 Added silc_client_check_silc_dir, silc_client_create_identifier
7434 and silc_client_load_keys.
7436 * Implemented SILC protocol compliant public key. Added public
7437 and private key saving to and loading from files.
7439 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7440 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7441 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7442 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7443 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7445 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7446 silc_pkcs_load_[public/private]_key.
7448 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7450 * Added silc_server_get_route (route.[ch]) to get connection
7451 data for the fastest route for given ID.
7453 * Implemented INVITE command on client and server. The command
7454 were re-defined in the SILC Protocol Specification and the
7455 implementation now complies with the specification.
7457 * Implemented PING command on client and server.
7459 * Implemented NAMES command on client and server. The server side
7460 supports currently only normal server not router server yet.
7461 Some changes to NAMES definition in SILC protocol specification.
7463 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7465 * Implemented LEAVE command on client and server.
7467 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7468 again. This change was made to the protocol as well. Server
7469 should not violate the protocol specification anymore.
7471 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7473 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7474 was tested. SOCKS4 was not but should work anyway.
