1 Tue Mar 19 12:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added silc_rng_get_byte_fast function in to the
4 lib/silccrypt/silcrng.[ch].
6 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
8 * Added macro SILC_PACKET_DATALEN which can be used during
9 packet assembling to check whether the data to be added to
10 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
11 len is truncated until it fits it.
13 Added checks for maximum length of channel message payload and
14 private message payload also.
16 Added checks for maximum packet length in server and in
19 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
20 lib/silcclient/client.c, lib/silccore/silcchannel.c and
21 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
22 lib/silcclient/client_prvmsg.c.
24 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
26 * Added silc_server_packet_queue_purge call to the
27 silc_server_disconnect_remote to assure that all data in the
28 queue before disconnecting is sent to the network. Affected
31 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
33 * Added the deleting of server's own ID cache entry to the
34 silc_server_free function. Free also everything else that
35 has been allocated in silc_server_init. The affected file
38 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
40 * Added functions silc_parse_version_string, silc_version_to_num,
41 and silc_ske_parse_version to parse SILC protocol style version
42 strings. Affected files lib/silcutil/silcutil.[ch] and
43 lib/silcske/silcske.[ch].
45 * Added new configuration params: version_protocol, version_software
46 and version_software_vendor to specify what version the remote
47 host must at least be to be able to connect to server. The vendor
48 string can be regex matched too. Added new function
49 silc_server_connection_allowed to check maximum number of allowed
50 connections, and allowed versions for incoming connections.
51 Affected files are silcd/server.c, server_util.[ch] and
54 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
56 * Added preliminary support for signals in scheduler. The
57 signals we care about are now blocked always when the scheduler
58 is locked. This way we can synchronise the use of signal with
59 scheduler. It is guaranteed that when signal occurs the scheduler
60 is not locked, and thus new tasks can be safely added to the
63 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
64 to silc_schedule_internal_init and silc_schedule_internal_uninit.
65 Added new platform specific routines
66 silc_schedule_internal_signals_[un]block and
67 silc_schedule_internal_signal_[un]register.
69 Added new functions to SILC Schedule API:
70 silc_schedule_signal_[un]register. Each signal that application
71 is going to use should be registered to the scheduler.
73 Affected files are lib/silcutil/silcschedule.[ch],
74 lib/silcutil/*/silc*schedule.c.
76 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
78 * Check for unauthenticated client and server in the
79 silc_server_new_client and silc_server_new_server functions.
80 Affected file silcd/packet_receive.c.
82 * Added function silc_string_is_ascii to check whether given
83 string is 7-bit ASCII string. Affected files are
84 lib/silcutil/silcutil.[ch].
86 * Added function silc_id_is_valid_server_id into the
87 silcd/serverid.c and added checking for valid Server ID's in
88 silc_server_new_server. The Server ID must always be based
89 on the server's public IP address.
91 * Added logging of DISCONNECT packet message in the server.
92 Affected file silcd/server.c.
94 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
96 * Changed all library interfaces that use Global RNG to also
97 accept SilcRng as argument. Affected files are
98 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
99 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
100 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
101 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
104 * Added function silc_pkcs_generate_key to the
105 lib/silccrypt/silcpkcs.[ch] for applications so that they
106 don't need to do pkcs->pkcs->init calls anymore.
108 * Remove SilcSocketConnection from the SFTP API since it really
109 wasn't needed there. The application has the information
110 saved in its contexts anyway and the SFTP layer doesn't need
111 know about it. Affected files lib/silcsft/silcsftp.h and
112 lib/silcsftp/sftp_[server/client].c.
114 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
115 The SilcSimContext is not SilcSim.
117 * Fixed possible buffer overflows in silc_id_render in the
118 lib/silcutil/silcutil.c.
120 * On EPOC the global crypto module lists are not used at all
121 in the crypto library. Added support for using the constant
122 algorithm list on EPOC. Affected files are
123 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
126 * Fixed the handling of third parameter of KICKED notify, since
127 it was mistakenly updated to SILC Protocol 1.0 even though it
128 is to be included in 1.1. Since it is not in 1.0 it is not
129 mandatory, and this fix now handles it only if it is provided,
130 and it is not error if it is not provided. Affected file
131 lib/silcclient/client_notify.c.
133 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
135 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
136 client. Affected file irssi/src/silc/core/client_ops.c.
138 * Merged with Irssi 0.8.4 from irssi.org CVS.
140 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
142 * Check for valid socket connection in client entries before
143 sending any messages. Fixes a crash, but doesn't fix some
144 other underlaying bug that is lurking there. Affected
145 file silcd/packet_send.c.
147 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
149 * $usermode, $cumode and $cumode_space expandos shouldn't do
150 anything with non-SILC server records. Affected file
151 irssi/src/silc/core/silc-expandos.c
153 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
155 * Fixed the silc_net_check_[host/local]_by_sock to support
156 IPv6 bound sockets as well. Now they can return IPv6 addresses
157 as well. Affected file lib/silcutil/silcnet.c.
159 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
160 Affected lib/silcutil/unix/silcunixnet.c.
162 * Fixed ID rendering (at least on some platforms, not NetBSD)
163 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
165 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
167 * Added silc_hash_public_key and silc_hash_public_key_compare
168 functions to be used with SilcHashTable. They can be used to
169 hash public keys and compare public keys in hash table. Affected
170 file lib/silcutil/silcutil.[ch].
172 * Added support for specifying multiple public keys for Client
173 connection section in server configuration file. This makes it
174 possible to accept multiple public keys from same host, or to
175 make a section that accepts any incoming host, and have the
176 accepted public keys listed in the section.
178 Added functions silc_sever_[find/get]_public_key, added the
179 support for this actually to all connection sections but only
180 the Client section is currently allowed to specify multiple
183 Affected files are silcd/server.c, server_internal.h,
184 command.c, protocol.c, server_util.[ch], packet_receive.c.
186 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
188 * Merged Irssi 0.8.2 from irssi.org CVS.
190 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
192 * If silc_debug is TRUE, also output standard logging messages
193 to stderr with the debug output.
195 Made silc_log_reset_all() flushing all channels before returning.
196 Also fixed some documentation typos.
198 Affected files are lib/silcutil/silclog.[ch].
200 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
202 * Fixed the server to check correctly the amount of connections
203 from single host, by checking also the type of the connection.
204 Fixed also the comparison of number of connections and number
205 of allowed connections. Affected files are silcd/server.c,
208 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
210 * Fixed the USERS command reply to save the user's mode on the
211 channel as well. Fixed JOIN command reply to check whether a
212 client is on channel already and not join it twice. Affected
213 file lib/silcclient/command_reply.c.
215 * Added new file silc-expandos.c into irssi/silc/core/ to return
216 various stuff for various signal for the statusbar etc. updating.
217 Now Irssi SILC client prints channel user modes etc. on the
220 * The user mode (like server/router operator changes) is now shown
221 on the Irssi SILC client's statusbar. The affected files are
222 irssi/src/silc/core/client_ops.c, silc-expandos.c.
224 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
226 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
227 to SILC_SCHEDULE_[UN]LOCK macros.
229 * Added more error printing to logs in server code. Affected
230 files silcd/server.c and silcd/protocol.c.
232 * Fixed -S option parsing in Irssi SILC Client. Affected file
233 irssi/src/silc/core/silc-core.c.
235 * Added silc_buffer_alloc_size function. Affected file is
236 lib/silcutil/silcbuffer.h.
238 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
240 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
241 constants. Affected files in
242 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
245 * Changed the internal SFTP Memory FS table to const. Affected
246 file lib/silcsftp/sftp_fs_memory.c.

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

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

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

329 to the lib/silcutil/silcbuffer.h.
331 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
333 * Added `user_count' to the SilcChannelEntry which now tells the
334 number of users on the channel. The user count is now saved
335 in normal server of global channels as well. Affected files
336 silcd/server.c, idlist.h, packet_receive.c and command.c.
338 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
339 include file utility functions.
341 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
342 instead of calling directly OS routines.
344 * Fixed NICK change printing in Irssi SILC Client. Fixed
345 KICKED notify printing in Irssi SILC Client. Affected file
346 irssi/src/silc/core/client_ops.c.
348 * Fixed a NICK change bug in client library, to not recreate the
349 client_entry->channels hash table everytime nick is changed.
350 Affected file lib/silcclient/client.c.
352 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
354 * ROBOdoc documented the lib/silcske/silcske.h, and improved
355 the SKE interface a bit.
357 * Fixed padding problem in PKCS#1. The padding was not actually
358 random since the random number generator was used incorrectly.
359 This security bug affects only when encrypting with PKCS#1, and
360 it is not currently used at all in SILC. SILC only use signing
361 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
363 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

412 section structs, now identifying the param directly.
414 Added CONFIG_FREE_AUTH macro in config file parsing.
416 Affected files are silcd/serverconfig.[ch].
418 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>

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

502 * The silc_cipher_register, silc_hash_register and
503 silc_hmac_register now checks if the object to be registered
504 is registered already. Affected files are
505 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
507 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

533 * Fixed the file transfer's key agreement payload to include
534 zero port also if the hostname is NULL because it could not
537 Call file transfer monitor callback now also if error occurs
538 during key agreement protocol.
540 Changed the silc_client_file_send interface to return the
541 SilcClientFileError instead of session id. The session ID
542 is returned into pointer provided as argument.
544 Check that the file exists locally before sending the
545 file transfer request at all.
547 Affected file lib/silcclient/client_ftp.c, silcapi.h.
549 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
550 error than can occur while key agreement protocol. Affected
551 file lib/silcclient/silcapi.h.
553 * Fixed the event_mode CMODE handler to not crash when mode
554 is changed and +k mode is set in the channel. Affected file
555 irssi/src/silc/core/silc-channels.c.
557 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
558 SILC_LOG_WARNING to give out Warning and not Error. Affected
559 file lib/silcutil/silclog.c.
561 * Fixed the channel message payload decryption in the function
562 silc_channel_message_payload_decrypt to not modify the original
563 buffer before it is verified that the message decrypted
564 correctly. Otherwise, next time it is called with correct
565 channel key it won't encrypt since the payload is corrupted.
566 Affected file lib/silccore/silcchannel.c.
568 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
570 * Do not constantly resize the window. A fix patch by cras.
571 Affected file irssi/src/fe-text/screen.c.
573 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
575 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
576 Affected file lib/silcutil/silcnet.c.
578 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
580 * Fixed a bug in hash table internal routine for traversing
581 the table with foreach callback. The current entry may
582 become invalid in the callback but it was referenced after
583 the callback returned.
585 Do not allow auto rehashing of hash table during the
586 silc_hash_table_foreach operation, for same reasons as it is
587 not allowed for SilcHashTableList. Affected files are
588 lib/silcutil/silchashtable.[ch].
590 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
592 * Defined DLLAPI into silcincludes.h and silcwin32.h for
593 Win32 DLL. extern's in header files are now declared with
596 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
598 * Fixed private message handling. It used some old code that
599 caused the client to crash. Affecte file is
600 lib/silcclient/client_prvmsg.c.
602 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
604 * Added function silc_client_add_channel,
605 silc_client_replace_channel_id, and removed functions
606 silc_client_new_channel_id and silc_idlist_get_channel_by_id
609 * Added cross reference of the joined channels to the
610 SilcClientEntry, and changed the SilcChannelEntry's
611 users list to SilcHashTable. The affected files are
612 lib/silcclient/idlist.[ch].
614 * Fixed a bug in hash table tarversing. While the hash table
615 is traversed with SilcHashTableList the table must not be
616 rehashed. It is now guaranteed that auto rehashable tables
617 are not rehashed while tarversing the list. Also defined that
618 silc_hash_table_rehash must not be called while tarversing
619 the table. Added function silc_hash_table_list_reset that must
620 be called after the tarversing is over. The affected files are
621 lib/silcutil/silchashtable.[ch].
623 * Changed all hash table traversing to call the new
624 silc_hash_table_list_reset in server and in client library.
626 * Added function silc_client_on_channel to return the
627 SilcChannelUser entry if the specified client entry is joined
628 on the specified channel. This is exported to application as
629 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
631 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
633 * Fixed founder regaining problem with JOIN command on normal
634 server. The notify for mode change must be sent always and
635 not only if !cmd->pending. Affected file silcd/command.c.
637 * Fixed the WHOWAS command's reply sending to support the
638 lists correctly. Affected file silcd/command.c.
640 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
642 * When sending JOIN command to router for processing the
643 sender's old command identifier was not saved back to the
644 sender's command context, fixed now. The affected file is
647 * Create the key in JOIN command of the router did not return
648 the channel key, added check for this. Affected file is
651 * Fixed a channel ID update bug in JOIN command reply. Do
652 not directly upgrade the ID but call the function
653 silc_idlist_replace_channel_id if the ID was changed.
654 Affected file silcd/command_reply.c.
656 * Fixed memory leaks from command calling if it would fail.
657 Affected file silcd/command.c.
659 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
661 * Applied patches from cras:
663 Memory leak fixes around libaries, irssi window resize fix,
664 new silclist.h and silcdlist.h, all extern inline changed to
667 * Removed dotconf from lib/dotconf, not needed anymore.
669 * Removed TRQ from lib/trq, not needed anymore.
671 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
672 with server connections. Later this will be configurable
673 in config file after new config file is done. Affected file
676 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
678 * Fixed a crash in server related to channel announcements.
679 Affected file silcd/server.c.
681 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
683 * Fixed memory leaks in silc_server_create_new_channel*
684 functions. Affected file silcd/server.c.
686 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
687 which ID was changed. This way the router will send the
688 user list for the channel again, and server won't be in
689 desync in some rare circumstances. Affected file is
690 silcd/packet_receive.c.
692 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
694 * Check for NULL socket pointer in the function
695 silc_server_packet_send_to_channel_real. Affected file
698 * Fixed the BAN notify handling to correctly remove ban
699 list. Affected file silcd/packet_receive.c.
701 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
703 * Fixed some header addition to Toolkit distribution in
704 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
706 * Added lib/silcclient/client_ops_example.h as an template
707 file for application programmers to quickly start using
708 the SilcClientOperation functions in their application.
709 Updated the lib/silcclient/README as well to tell about this
710 nice file made available.
712 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
714 * Call silc_server_remove_from_channels when removing client
715 entry when NO_SUCH_CLIENT_ID was received. Affected file
716 is silcd/command_reply.c.
718 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
720 * Added server & router operator statistics updating. Affected
721 file silcd/packet_receive.c and silcd/command.c.
723 * Fixed the SERVER_SIGNOFF notify handling on normal server
724 not to save the history information for clients. Same was
725 fixed earlier in remove_clients_by_server function, but not
726 here. Affected file silcd/packet_receive.c.
728 * Raised the default connection-retry count from 4 to 7 in
729 server. Affected file silcd/server.h.
731 * Cancel any possible reconnect timeouts when we start the
732 key exchange. Affected file silcd/server.c.
734 * Do not reconnect on connection failure when SCONNECT was
735 given. Affected files silcd/server.[ch].
737 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
739 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
741 * Fixed the NICK command to always give the unformatted
742 nickname to the one giving the NICK command. If unformatted
743 nickname is cached already it will be formatted and the
744 local entry will always get the unformatted nickname.
745 Affected file lib/silcclient/idlist.c.
747 * Fixed some double frees from client library commands.
748 Affected file is lib/silcclient/command.c.
750 * Fixed CUMODE command in server to assure that no one can
751 change founder's mode than the founder itself, there was a
752 little bug. Affected file silcd/command.c.
754 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
756 * Removed the SilcClientCommandDestructor from the client
757 libary, it is not needed anymore. Affected files are
758 lib/silcclient/silcapi.h, command[_reply].[ch],
759 client_notify, idlist.c.
761 * Fixed GETKEY command to first resolve client, and then
762 resolve the server only if the client was not found, instead
763 of resolving both at the same time. Affected file is
764 lib/silcclient/command.c.
766 * Added silc_client_start_key_exchange_cb and lookup the
767 remote hostname and IP address before starting the key
768 exchange with server. The affected file is
769 lib/silcclient/client.c.
771 * The server's public key is now saved using the IP address
772 of the server and not the servername for the filename.
773 The hostname public key filename is checked as an fall back
774 method if the IP address based filename is not found.
776 Fixed the GETKEY command to save the fetched server key
779 Print the remote server's hostname now when new key is
780 received during connection process. Affected file is
781 irssi/src/silc/core/client_ops.c.
783 * Return always our own public key to the client if it asks
784 for it with GETKEY command. Affected file silcd/command.c.
786 * Removed the use_auto_addr variable from default config
787 file since it was in wrong section. Affected file is
790 * Fixed TOPIC_CHANGE notification to not route it when it
791 was sent using silc_server_send_notify_to_channel function.
792 Affected file silcd/command.c.
794 * Fixed silc_server_send_notify_kicked to send the kicker's
795 Client ID also, it was missing. Affected files are
796 silcd/command.c, silcd/packet_send.[ch].
798 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
800 * Do not save client history information in SERVER_SIGNOFF.
801 Fixes the bug in normal server that it does not detect
802 the client becoming valid after the server becomes back
803 online. Affected file silcd/server_util.c.
805 * Added `sock_error' field into the SilcSocketConnection
806 context. When error occurs during socket operation (read
807 or write) the error is saved. Added also new function
808 silc_socket_get_error to return human readable socket error
809 message. Affected files are lib/silcutil/silcsockconn.[ch],
810 lib/silcutil/unix/silcunixsockconn.c, and
811 lib/silcutil/win32/silcwin32sockconn.c.
813 * The server now prints the socket error message in the
814 signoff for client. Affected file silcd/server.c.
816 * Fixed the `created' channel information sending from router
817 to server in JOIN command. Checks now whether the channel
818 really was created or not and set it according that.
820 Fixed the JOIN command to use the client entry's current
821 ID during the joining procedure instead of the one it sent
822 in the command (it is checked though), since it can change
823 between the packet processing and command processing, and
824 would just case unnecessary pain in the client end. Affected
825 file silcd/command.c.
827 * Fixed a channel key payload sending to use correct channel
828 ID when the server was forced to change the channel's ID by
829 router. Router sent the key payload with the old Channel ID.
830 Affected file silcd/packet_receive.c.
832 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
834 * Call silc_server_save_channel_key only if the key payload
835 was provided in the JOIN command's command reply. Affected
836 file silcd/command_reply.c.
838 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
840 * Fixed silc_mp_sizeinbase to return the value correctly with
841 MPI. Affected file lib/silcmath/mp_mpi.c.
843 * Fixed the stop_server signal to correctly stop the scheduler
844 and gracefully stop the server when SIGTERM or SIGINT signals
845 are received. Affected file silcd/silcd.c.
847 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
849 * Simple handling of TERM and HUP signals. Also added some log
850 flushing call around. Affected file is
853 * Fixed small bugs in silclog.c. Now buffering output will take
854 effect after 10 seconds since startup: This will ensure that
855 no important startup messages are lost. Also output redirection
856 will preserve original format ([Date] [Type] message).
857 Affected file is lib/silcutil/silclog.c.
859 * Added two options to the config file, in the logging section:
860 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
861 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
863 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
865 * Do not print the warning about log files not being initialized
866 more than once to avoid excess logging. Affected file is
867 lib/silcutil/silclog.c.
869 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
870 the SIM copying in make install in Makefile.am.pre.
872 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
874 * Rewritten silclog APIs. Globally interesting changes follows:
875 silc_log_set_files() changed to silc_log_set_file().
876 silc_log_set_callbacks() changed to silc_log_set_callback().
877 ROBOdoc documented silclog header file.
878 SilcLogCb now returns bool to wether inihibit the default
879 handler or not (to keep the old behaviour return always TRUE).
880 The new APIs should also fix the problem of the
881 silcd_error.log file that was written in the current directory.
884 Log files streams will remain opened after silc_log_set_file()
885 call, means less CPU usage notably on high traffic servers.
886 File streams are now full buffered, and flushed to the disk
887 every 5 minutes, lesses HD activity and CPU usage.
888 Messages can be redirected, allowing admins to configure
889 one single logfile for all server messages.
890 the silc_log_quick global variable to activate fast-logging.
891 Affected files lib/silcutil/silclog.[ch]
893 * Changed some code to conform new silclog APIs. Affected
894 files are doc/example_silcd.conf.in, silcd/server.c
895 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
898 * Fixed a memory leak that could occur in some situations.
899 Affected file silcd/serverconfig.c.
901 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
903 * Added the silc_client_del_client to remove the client from
904 all channels as well. Affected file lib/silcclient/idlist.c.
906 * Fixed the client library to correctly remove the client
907 from all channels when the client entry is being destroyed.
908 Affected file lib/silcclient/client_notify.c, command.c.
910 * Added auto-nicking support to the client library. If the
911 applicatio now sets client->nickname it will be sent to the
912 server after connecting by the library. This way for example
913 SILCNICK (or IRCNICK) environment variables will have effect
914 and always change the nickname automatically to whatever
915 it is wanted. Affected file lib/silcclient/client.[ch].
917 * Renamed silc_server_command_bad_chars to the
918 silc_server_name_bad_chars and moved it to the
919 silcd/server_util.[ch]. Added also new function
920 silc_server_name_modify_bad to return nickname that
921 includes bad characters as new nickname without those
922 bad characters. This check and modify is now used in
923 silc_server_new_client when the username is initially set
924 as nickname, so it must be checked to be valid nickname.
925 Affected file silcd/packet_receive.c.
927 * The nickname length is now taken from the packet for real
928 and not trusted to strlen() since it clearly can return
929 wrong length for nickname including bad characters. This
930 also applies to channel names. Affected file silcd/command.c.
932 * Removed the lib/silcsilm/modules directory. Modules are now
933 compiled into the lib/silcsim. Fixed the copying of the
934 modules to follow symbolic links in Makefile.am.pre.
936 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
938 * Fixed silc_string_regexify list creation. Fixes bugs with
939 BAN and INVITE commands in server. The affected file is
940 lib/silcutil/unix/silcunixutil.c.
942 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
944 * Removed the command destructor entirely from the server's
945 command and command reply routines. It is not needed, and
946 its usage was buggy and caused crashes. Affected files are
947 silcd/command[_reply].[ch].
949 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
951 * Cancel protocol and NULL sock->protocol if timeout
952 occurred during protocol. Affected file silcd/server.c.
954 * Cancel protocol timeouts always before calling the final
955 callback, to assure that after final callback is called
956 no other state will be called for the protocol anymore.
957 Affected file silcd/protocol.c.
959 * Print error log if incoming connection configuration could
960 not be found. Affected file silcd/server.c.
962 * Fixed JOIN command to correctly save the founder mode
963 to the client on normal SILC server, when the channel
964 was created by the router. Affected file silcd/command.c.
966 * Fixed LIST command (hopefully) to send correct reply
967 packets. Affected file silcd/command.c.
969 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
971 * The silc_packet_receive_process now returns FALSE if the
972 read data was invalid packet, and TRUE if it was ok.
974 The server now checks that if unauthenticated connection
975 sends data and its processing fails the server will close
976 the connection since it could be a malicious flooder.
978 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
980 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
982 * Make sure the warning about error opening a log file is
983 printed only once and not everytime it fails (produces
984 too much useless log). Affected file lib/silcutil/silclog.c.
986 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
988 * Made the silc_server_daemonise() function more readable.
989 Affected file silcd/server.c.
991 * Pid file is now optional, the user may comment it out from
992 the config file. Removed define SILC_SERVER_PID_FILE, we
993 don't need a default any longer. Affected file
994 configure.in.pre, lib/Makefile.am.pre.
996 * Make some use of the pid file. The server now dies at startup
997 if it detects a valid pid file on his path. The server would
998 die anyway in this circumstance, because of the bind() failure.
999 Affected file silcd/silcd.c.
1001 * No longer compiling lib/dotconf.
1003 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1005 * Fixed JOIN command parsing not to crash. Affected file
1006 lib/silcclient/command.c.
1008 * Fied the NICK_CHANGE notify to add the new client entry
1009 even it is resolved. This removes an <[unknown]> nick
1010 thingy bug in the client. Affected file is
1011 lib/silcclient/client_notify.c.
1013 * Do not try to allocate 0 bytes (efence does not like it)
1014 in lib/silccore/silccomand.c when encoding payload.
1016 * Do not take IRCNICK as nickname in Irssi SILC client since
1017 it is not possible to set nickname before hand connecting
1018 the server (TODO has an entry about adding auto-nicking
1021 * Changed the silc_server_command_pending to check whether
1022 there already exists an pending entry with the specified
1023 command, command identifier and pending callback. This is
1024 to fix IDENTIFY and WHOIS related crashes that may register
1025 multiple pending commands with same identifier. Affected
1026 file silcd/command.c.
1028 * Fixed the server to reconnect to the router even if it
1029 was already reconnecting and EOF was received. This to
1030 fix a possibility that the server wouldn't ever try to
1031 auto-reconnect to the router. Affected file silcd/server.c.
1033 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1035 * Fixed the server's password authentication to use the
1036 length of the locally saved password, and not the one
1037 sent in the packet. Affected file silcd/protocol.c.
1039 * Fixed same password authentication problem in the
1040 Authentication Payload handling routines in
1041 lib/silccore/silcauth.c.
1043 * Yet another password authentication problem fixed with
1044 channel password handling in silcd/command.c.
1046 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1048 * If first character of string in silc_parse_userfqdn is '@'
1049 then do not parse it. Affected file is
1050 lib/silcutil/silcutil.c.
1052 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1054 * Fixed minor bug in IDENTIFY command reply sending, which
1055 caused various weird problems during JOIN when it was
1056 resolving names for users. Affected file silcd/command.c.
1058 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1060 * Fixed the IDENTIFY command reply sending to chech better valid
1061 clients. It was possible to send incomplete list of replies.
1062 Affected file silcd/command.c.
1064 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1066 * Added silc_client_command[s]_[un]register functions now to
1067 dynamically register the commands in client library. Removed
1068 the static table of commands. This allows the client library
1069 to call commands without causing the application to know about
1070 what commands library has called.
1072 Removed the INFO command reply kludge to detect when the command
1073 was called by library. Now library use its own command reply
1074 function for INFO command.
1076 Added function silc_client_command_call to call a command.
1077 Application can use it to call command, not access the structure
1080 Now all commands that are sent by the client library (not
1081 explicitly sent by application) use own command reply functions.
1083 Affected files around lib/silcclient/ and in
1084 irssi/src/silc/core/.
1086 * Fixed the WHOIS command reply sending to chech better valid
1087 clients. It was possible to send incomplete list of replies.
1089 Fixed the WHOIS and IDENTIFY to send the request to router
1090 if normal server did not do it and did not find any results.
1092 Affected file silcd/command.c.
1094 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1096 * Moved the internal data from SilcClient context into its
1097 own file, not accesible to application. Affected files
1098 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1099 and other files in client library.
1101 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1103 * Added doc/examples installation target in Makefile.am.pre.
1106 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1108 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1109 commands the found client entry will be removed from the
1110 cache, after notifying application about the error. Affected
1111 file lib/silcclient/command_reply.c.
1113 * Changed the /MSG to check for exact nickname user gave, and
1114 not let `nick' match `nick@host' if it is only one found. Now,
1115 user must type the exact nickname (like nick@host2) even if
1116 there are no more than one same nicks found. This is to avoid
1117 a possibility of sending nickname to wrong nickname since
1118 `nick' could match `nick@host'. Affected file is
1119 irssi/src/core/silc-servers.c.
1121 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1123 * Do not print "you are now server operator" or similar when
1124 giving /away command. Affected files are
1125 irssi/src/silc/core/client_ops.c, silc-servers.h.
1127 * Made the silc_server_command_pending_error_check to send
1128 the same command reply payload it received back to the
1129 original sender of the command. This way all arguments
1130 that was received by the server will be received by the
1131 client too. Affected file silcd/command.c.
1133 * Added the silc_idcache_add to return the created cache entry
1134 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1136 * Add global clients to expire if they are not on any channel.
1137 This is because normal server will never know if they signoff
1138 if they are not on any channel. The cache expiry will take
1139 case of these entries. This is done by normal servers only.
1140 The affected files are silcd/command_reply.c,
1141 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1143 * If server receives invalid ID notification for WHOIS or
1144 IDENTIFY and the ID exists in the lists, it is removed.
1145 Affected file silcd/command_reply.c.
1147 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1148 in client then client entry that it matches is searched and
1149 the nickname is printed on the screen for user. Affected
1150 file irssi/src/silc/core/client_ops.c.
1152 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1154 * Use cache entry expire time in the LIST command reply to
1155 purge old entries from the cache after the LIST command
1156 reply has been received. This way we don't have non-existent
1157 entries in the cache for too long. Affected file is
1158 silcd/command_reply.c.
1160 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1162 * If we are normal server, and we've not resolved client info
1163 in WHOIS or IDENTIFY from router, and it is global client,
1164 we'll check whether it is on some channel. If it is not
1165 then we cannot be sure about its validity and will resolve it
1166 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1167 file silcd/command.c.
1169 * Search channel by name (if possible) rather than by ID
1170 in IDENTIFY command's command reply. Affected file is
1171 silcd/command_reply.c.
1173 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1175 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1176 Updated specs and implemented it. Affected file silcd/command.c,
1177 silcd/packet_send.c and silcd/packet_receive.c.
1179 * Implemented the <founder auth> payload handling in the JOIN
1180 command. If provided all conditions for channel joining
1181 except requirement to provide correct passphrase can be
1182 overrided by the channel founder. Updated the protocol specs.
1183 Affected file silcd/command.c.
1185 Added support for founder auth in JOIN command in client
1186 library. Fixed the parsing of the JOIN command now to support
1187 all options as they should be. The affected file is
1188 lib/silcclient/command.c.
1190 * Optimized the WHOIS and IDENTIFY commands to send the request
1191 to router only if it includes nicknames or other names. If
1192 they include only IDs then check the local cache first before
1193 routing. Affected file is silcd/command.c.
1195 * Added channels topic announcements. Affected file is
1196 silcd/packet_receive.c and silcd/server.c.
1198 * Fixed the silc_server_send_notify_topic_set to really destine
1199 the packet to channel. Affected file silcd/packet_send.c.
1201 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1202 library. Affected file lib/silcclient/client_notify.c.
1204 * Added UMODE announcements. Affected file silcd/server.c.
1206 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1208 * Memory leak fixes in:
1210 lib/silcutil/silcsockconn.c
1211 lib/silcske/silcske.c
1212 lib/silcske/groups.c
1214 lib/silccrypt/silcpkcs.c
1215 lib/silccore/silccommand.c
1216 lib/silccore/silcidcache.c
1221 * ROBOdoc documented the lib/silcske/groups.h file and a
1222 bit changed the interface for better.
1224 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1226 * Update the client entry context in the ID cache after
1227 nick change. Affected file lib/silcclient/command.c.
1228 Fixes the CUMODE command when regaining founder privileges,
1229 and a little WHOIS problem.
1231 * Fixed silc_net_gethostbyname to correctly call the
1232 inet_ntop. Affected file lib/silcutil/silcnet.c.
1234 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1236 * Added IPv6 support checking to the configure.in.pre, added
1237 also --enable-ipv6 option to override the check. Affected
1238 file configure.in.pre.
1240 * The silc_thread_create now calls the start function
1241 directly if threads support is not compiled in. Removes
1242 ugly #ifdef's from generic code. Affected files are
1243 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1245 * Added silc_net_gethostby[name/addr]_async to asynchronously
1246 resolve. Affected files are lib/silcutil/silcnet.[ch].
1248 * Added support for rendering IPv6 based server, client and
1249 channel IDs. Affected file lib/silcutil/silcutil.c.
1251 * Added support for creating IPv6 based server IDs. Affected
1252 file is silcd/serverid.c.
1254 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1256 * Added silc_net_gethostby[addr/name] into the
1257 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1258 routines. Added silc_net_is_ip[4/6]. Affected file is
1259 lib/silcutil/unix/silcunixnet.c. All routines that take
1260 address as argument now supports both IPv4 and IPv6 addresses.
1262 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1264 * Fixed LIST command reply sending in server. Affected file
1267 * Server now sends the kicker's client ID in the KICK notify
1268 to the kicked client. Affected file silcd/command.c.
1270 * The client library now parses the kickers client ID and
1271 UI displays it. Affected files lib/silcclient/client_notify.c
1272 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1274 * Made all payload parsing function prototypes consistent.
1275 They all take now const unsigned char * and uint32 pair as
1276 the payload data instead of SilcBuffer. Changes all around
1277 the source tree. Other unsigned char* -> const unsigned char*
1278 changes around the tree as well.
1280 * Optimized SFTP client and server packet sending not to
1281 allocate new buffer for each packet but to recycle the
1282 first allocated buffer. Affected files are
1283 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1285 * Optimized the SFTP client to use SilcList instead of
1286 SilcDList for requests, because it is faster. Affected file
1287 is lib/silcsftp/sftp_client.c.
1289 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1290 into lib/silccore/silcid.[ch].
1292 Renamed silcpayload.[ch] into silcargument.[ch].
1294 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1296 * If client entry is deleted with active key agreement
1297 session, abort the session.
1299 The silc_client_abort_key_agreement now calls the completion
1300 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1302 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1305 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1307 * Don't use __restrict in older GCC's. Affected file is
1308 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1310 * silc_net_localhost now attempts to reverse lookup the
1311 IP/hostname. Affected file lib/silcutil/silcnet.c.
1313 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1314 command. It can be used to gain founder privileges at
1315 the same time when joining the channel.
1317 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1318 kicker's client ID as well. Updated protocol specs.
1320 Defined that the server must send SILC_COMMAND_IDENTIFY
1321 command reply with error status to client who sent
1322 private message with invalid client ID.
1324 Updated the protocol specification.
1326 * Added silc_server_send_command_reply to send any
1327 command reply. Affected file silcd/packet_send.[ch].
1329 * Added silc_id_payload_encode_data to encode ID payload
1330 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1332 * The server now send IDENTIFY command reply with error
1333 status if client ID in private message is invalid. Affected
1334 file silcd/packet_receive.c.
1336 * Save the server key file with server's IP address in
1337 the filename instead of hostname. The affected file is
1338 irssi/src/silc/core/client_ops.c.
1340 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1345 * Added libtool support for compiling shared objects in
1346 lib/silcsim. Affected file configure.in.pre and
1347 lib/silcsim/Makefile.am. Original patch by cras.
1349 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1351 * Pid file configuration, and server's config file fixes
1352 patch by toma. Updated CREDITS file.
1354 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1356 * Fixed silc_client_channel_message to not try to decrypt
1357 the message twice if it resolved the destination client
1358 information. This could cause of dropping one channel
1359 message. Affected file lib/silcclient/client_channel.c.
1361 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1364 lib/silcclient/client.c. This function is used when the SILC
1365 Client is run under some other scheduler, or event loop or
1366 main loop. On GUI applications, for example this may be
1367 desired to used to run the client under the GUI application's
1368 main loop. Typically the GUI application would register an
1369 idle task that calls this function multiple times in a second
1370 to quickly process the SILC specific data.
1372 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1374 * Fixed silc_server_drop() for dropping the supplementary
1375 groups as well, this could cause a security hole on some
1378 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1383 * Write PID file after dropping privileges. Added -F option
1384 to run server on foreground. A patch by debolaz.
1385 Affected files silcd/server.c, silcd/silcd.c.
1387 * Fixed MOTD to return the MOTD file server name. Affected
1388 file silcd/command.c.
1390 * Added INFO command reply handling to the Irssi SILC Client.
1391 Affected file irssi/src/silc/core/client_ops.c.
1393 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1395 * Fixed the silc_idcache_list_* routines to really support
1396 the dynamic list. Fixes a crash. Affected file is
1397 lib/silccore/silcidcache.c.
1399 * Fixed the LIST command reply to really call LIST command's
1400 pending callbacks. Affected file silcd/command_reply.c.
1402 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1404 * Update conn->local_entry->nickname after giving NICK
1405 command. Affected file lib/silcclient/command.c.
1407 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1409 * Added the [pid] option to the silcd configuration file
1411 Affected files: serverconfig.[ch] and silcd.c
1413 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1415 * Save fingerprint in WHOIS command reply in server.
1416 Affected file silcd/command_reply.c.
1418 * Fixed NICK commands pending callback registration.
1419 Affected file lib/silcclient/command.c.
1421 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1423 * Use ++server->cmd_ident when sending commands in server,
1424 instead of random number. Affected file silcd/command.c.
1426 * Fixed GETKEY command reply to call actually GETKEY pending
1427 command callbacks. Affected file silcd/command_reply.c.
1429 * A bit stricter check for nicknames. Check for same nickname
1430 in NICK command also. Affected file silcd/command.c.
1432 * Do not call INFO command everytime client ID changes, only
1433 during first connecting. Affected file lib/silcclient/client.c.
1435 * Set the new nickname only after successful command reply for
1436 NICK command is returned by server. Affected file
1437 lib/silcclient/command.c.
1439 * Remove nicknames from nicklist during server_signoff notify.
1440 Should fix /NAMES bit more. The affected file is
1441 irssi/src/silc/core/silc-channels.c.
1443 * Added `fingerprint' field to the SilcIDListData in the
1444 silcd/idlist.h to hold the fingerprint of the client's
1447 Send the fingerprint of the client's public key in WHOIS
1450 Affected files silcd/command.c, and silcd/idlist.[ch].
1452 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1453 create fingerprint from given data.
1455 * Show the fingerprint of the client's public key in WHOIS.
1456 Affected files irssi/src/module-formats.[ch] and
1457 irssi/src/silc/core/client_ops.c.
1459 * Format the multiple same nicknames also during JOIN and
1460 NICK_CHANGE notifys. Affected file is
1461 lib/silcclient/client_notify.c.
1463 * Do not print error on screen for invalid private message
1464 payload since it can come if someone is sending private
1465 messages with wrong key. Affected file
1466 lib/silccore/silcprivate.c.
1468 * Fixed multiple concurrent /PING crash. Affected file
1469 lib/silcclient/command.c.
1471 * Changed the wrong ID encoding. All IP addresses must be
1472 in MSB first order in encoded format. They were encoded
1473 wrong and was in LSB format. Affected files are
1474 silcd/serverid.c, lib/silcutil/silcutil.c.
1476 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1478 * Call the `connect' client operation through the scheduler
1479 in case of error. Affected file lib/silcclient/client.c.
1481 * Call the `failure' client operation even if the error
1482 occurred locally during a protocol. Affected file is
1483 lib/silcclient/protocol.c.
1485 * Added support of sending LIST command to router from normal
1486 server. This way normal server can get list of all channels
1487 in the network too. Fixed the channel list sending in the
1488 server too. Affected files are silcd/command.c, and
1489 silcd/command_reply.[ch].
1491 * Added silc_server_update_channels_by_server and
1492 silc_server_remove_channels_by_server. They are used during
1493 disconnection of primary router and in backup router protocol.
1494 Affected file silcd/server_util.[ch], silcd/server.c and
1495 silcd/server_backup.c.
1497 * Fixed channel adding to global list in IDENTIFY command
1498 reply in server. Affected file silcd/command_reply.c.
1500 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * If the incoming packet type is REKEY or REKEY_DONE process
1503 that packet always synchronously. Fixes yet another MAC
1504 failed error on slow (dialup) connections. Affected file
1505 lib/silcclient/client.c and silcd/server.c.
1507 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1509 * Call check_version SKE callback for initiator too. Affected
1510 file lib/silcske/silcske.c.
1512 * Implemented fix for security hole found in the SKE that was
1513 fixed in the specification few days back; the initiator's
1514 public key is now added to the HASH value computation.
1515 Added backwards support for the old way of doing it too, for
1516 old clients and old servers. Affected file is
1517 lib/silcske/silcske.c.
1519 * Enabled mutual authentication by default in SKE. If initiator
1520 is not providing mutual authentication the responder will
1521 force it. This will provide the proof of posession of the
1522 private key for responder. The affected files are
1523 lib/silcclient/protocol.c and silcd/protocol.c.
1525 * Do not cache anymore the server's public key during SKE.
1526 We do mutual authentication so the proof of posession of
1527 private key is done, and if the server is authenticated in
1528 conn auth protocol with public key we must have the public
1529 key already. Affected file silcd/protocol.c.
1531 * Added new global debug variable: silc_debug_hexdump. If
1532 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1533 file lib/silcutil/silclog.[ch].
1535 * Fixed compilation warning due to char * -> const char *.
1536 Affected files lib/silcutil/silcnet.h, and
1537 lib/silccore/silcauth.[ch].
1539 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Fixed CMODE command when new channel key was created. If
1542 the creation failed the old key was removed. Next time giving
1543 same command would crash the server since the old key was
1544 freed already. Affected file silcd/command.c.
1546 * Fixed the silc_server_announce_get_channels to not crash
1547 on reconnect. Affected file silcd/server.c.
1549 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Added silc_log_set_debug_string function to set a regex
1552 string to match for debug output. Only the function names,
1553 or filenames matching the given debug string is actually
1554 printed. This way it is possible to filter out those debug
1555 strings that user is not interested in.
1557 Fixed a bug in silc_string_regexify.
1559 Affected files lib/silcutil/silclog.[ch], and
1560 lib/silcutil/unix/silcunixutil.c.
1562 * Changed the -d options in both server and Irssi SILC client
1563 to take the debug string as argument. Affected files
1564 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1566 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1568 * Added silc_hash_babbleprint to create a Bubble Babble
1569 Encoded fingerprint. The encoding is developed by Antti
1570 Huima (draft-huima-babble-01.txt), and it creates human
1571 readable strings out of binary data. Affected file
1572 lib/silccrypt/silchash.[ch].
1574 * Print the babble print now in addition of fingerprint as well
1575 in Irssi SILC client. Affected files are
1576 irssi/src/fe-common/silc/module-formats.[ch],
1577 irssi/src/fe-common/silc/core/client_ops.c.
1579 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1581 * Fixed a security problem found in SKE. The initiator's
1582 public key too is now added to the HASH hash value creation
1583 which is signed by the responder to create the SIGN value.
1584 This will prevent anyone in the middle to lie to the responder
1585 about the initiator's public key. If this is done now, the
1586 man in the middle will get caught. Updated the protocol
1589 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * Better installation directory handling. Configure module
1592 paths and other paths automatically to example_silc* files
1593 in doc/. A patch by toma.
1595 * Fixed compiler warning from MPI library, and from SILC RNG.
1598 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1599 It can be configured with ./configure. A patch by toma.
1601 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1603 * Find correct make to use in prepare-clean. A patch by
1604 toma. Affected file prepare-clean.
1606 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1608 * Added irssi variables use_auto_addr, auto_bind_ip,
1609 auto_bind_port and auto_public_ip.
1611 * Changed the interface for silc_client_send_key_agreement
1612 in lib/silcclient/silcapi.h
1616 irssi/src/silc/core/silc-core.c
1618 lib/silcclient/silcapi.h
1619 irssi/src/silc/core/silc-channels.c
1620 lib/silcclient/client_keyagr.c
1623 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1625 * Added silc_pkcs_public_key_compare to compare two
1626 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1628 * Check that the client who set the founder mode on the
1629 channel is the same client that is giving the founder
1630 mode to itself. It is done by comparing the saved public
1631 key (it is saved even in the authentication is passphrase).

1640 client library. Affected file lib/silcclient/client.c.
1642 * Fixed the silc_client_packet_parse to not to increase
1643 the packet sequence number if the conn->sock and the
1644 current socket connection is not same. This can happen
1645 for example during key agreement when the conn includes
1646 multiple socket connections (listeners). Affected file
1647 lib/silcclient/client.c.
1649 * The sender of the file transfer request now provides also
1650 the pointer (listener) for the key exchange protocol. If
1651 the listener cannot be created then it sends empty key
1652 agreement and lets the receiver provide the listener.
1654 Added `local_ip' and `local_port' arguments to the
1655 silc_client_file_send. If they are provided they are used,
1656 if not then it will attempt to find local IP address, if
1657 not found or bind fails then the remote client will provide
1660 Affected files are lib/silcclient/client_ftp.c and
1661 lib/silcclient/silcapi.h.

1670 of the client's public key (if the proof of posession of the
1671 corresponding private key is verified by the server).
1672 Updated to the protocol specification.
1674 * Added support of receiving the client's public key's
1675 fingerprint in command reply in client library. Affected
1676 file is lib/silcclient/command_reply.c, and
1677 lib/silcclient/idlist.[ch].

1736 preserve the WHOWAS info for the client. Affected file
1737 silcd/server_util.c.
1739 * Fixed SERVER_SIGNOFF notify handling in the server. The
1740 server is now able to process incoming SERVER_SIGNOFF notify
1741 for a server that it doesn't even know about. It will remove
1742 the clients provided in the notify. Affected file
1743 silcd/packet_receive.c.
1745 * Check for partial packet in data queue after every packet that
1746 was found from the queue. Return and wait for more data if
1747 there is partial data in queue. Affected file is

1769 * Added silc_rng_global_get_byte_fast to get not-so-secure
1770 random data as fast as possible. Random data is read from
1771 /dev/urandom if available and from the SILC RNG if not
1772 available. It is used in padding generation. Affected file
1773 lib/silccrypt/silcrng.[ch].
1775 * All packets in client library are now processed synchronously.
1776 Optimized packet processing a lot. Affected file

1790 be found by the first it cannot be found at all. Affected
1791 file lib/silcclient/client_notify.c.
1793 * Fixed WHOWAS command reply calling. Affected file
1794 lib/silcclient/command_reply.c.
1796 * Removed all references to silc_idlist_get_client from the
1797 Irssi SILC client since that call is internal call used by
1798 the library. The Irssi SILC client will use now client
1799 retrieval functions found in silcapi.h.
1801 * Fixed a bug in resolving nickname info before sending
1802 private message. It used freed memory. Affected file
1803 irssi/src/silc/core/silc-servers.c.

1825 Affected file lib/silcutil/silcnet.[ch].
1827 * If key exchange or rekey protocol is active for a connection
1828 parse all packets syncronously since there might be packets
1829 in packet queue that we are not able to process without first
1830 processing packets before them. Affected file silcd/server,
1831 lib/silcclient/client.c.
1833 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1834 whether library should continue processing the packet.
1835 Affected file lib/silccore/silcpacket.h.

1921 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1922 length for maximum padding up to 128 bytes). Affected
1923 file lib/silccore/silcpacket.h.
1925 * Removed all backwards support for old 0.5.x MAC thingies.
1926 The SILC packet header change makes it impossible to be
1927 backwards compatible.
1929 * Send the ENDING packet with timeout in the backup resuming
1930 protocol. This is to assure that all routers has connected
1931 to the primary router. Affected file silcd/server_backup.c.
1933 * Changed the RNG to take the first IV from random data. It
1934 used to take it from zero actually. Changed the RNG also

1958 * Allow backup router to announce servers. All servers
1959 announced by backup router are added to the global list
1960 automatically. Update hte server's socket to our primary
1961 router also when backup router announces a server.
1962 Affected file silcd/packet_receive.c.
1964 * Do not update the client->router in the function
1965 silc_server_udpate_clients_by_server if the client is on
1966 global list. We might fail to find any specific server
1967 for locally connected clients and local cell clients. They
1968 should still use the `from' and not `to' as client->router.
1969 This fixes backup router resuming protocol. Affected file
1970 silcd/server_util.c.
1972 * Decrease channel statistics count only if the channel
1973 deletion worked. Affected files are silcd/server.c and
1974 silcd/server_util.c.

1994 to the router it came from. Affected file is
1995 silcd/packet_send.c. Fixed memory leak too.
1997 * Announce informations for incoming router connection, but
1998 only after checking if it is replaced by backup router.

2015 * Changed the SFTP Filesystem interface. Changed the
2016 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2017 the filesystem operation function. The SilcSFTPFilesystem
2018 is now a context that is allocated by all filesystem allocation
2019 functions and it already includes the operations structure
2020 and filesystem specific context. It is given as argument
2021 now to the silc_sftp_server_start. This made the interface
2022 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2023 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2025 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2147 (SSH File Transfer Protocol). Affected file in addition
2148 of the internet draft is lib/silccore/silcpacket.h.
2150 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2151 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2152 is used as part of backup router protocol when the primary
2153 router of the cell is back online and wishes to resume
2154 the position as primary router.
2156 * Redefined the MAC generation keys in the protocol. The
2157 same key is not used anymore in both direction. Both
2158 direction will now use different keys for sending and
2159 receiving. This fixes a potential security flaw. This
2160 change causes incompatibilities in the protocol.
2162 * Redefined also the MAC computation from the packet.
2163 An packet sequence number is now added to the MAC
2164 computation. This prevents possible replay attacks against
2165 the protocol. This change too causes incompatibilities
2168 Added `sequence' field to the SilcPacketContext to hold
2169 the current sequence number for the packet.
2171 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2173 * Added `created' field to the SilcIDListData in the file
2174 silcd/idlist.h to indicate the time when the entry was
2177 * Added `created' field to the SilcChannelEntry too. Affected
2178 file silcd/idlist.h.
2180 * Added `creation_time' aguments to all the announcement functions
2181 in the server. If it is provided then only the entries that
2182 was created after the provided time frame are actually
2183 announced. Affected file silcd/server.[ch].
2185 * The protocol says that the Channel ID's IP address must be
2186 based on the router's IP address. Added check for this in
2187 the silc_server_new_channel when processing incoming New Channel
2188 Payload. Affected file silcd/packet_receive.c.
2190 * Print out the correct version with --version in SILC client.
2191 Affected file irssi/src/silc/core/silc-core.c.
2193 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Fixed WHOWAS command to check for completnes of the client
2196 entry always, not just when the command is coming from client.
2197 Affected file silcd/command.c.
2199 * Added new function silc_server_packet_queue_purge to purge the
2200 outgoing data queue to the network. After the function returns
2201 it is guaranteed that the outgoing packet queue is empty.
2202 Affected file silcd/packet_send.[ch].
2204 * Purge the outgoing packet queue in the rekey protocol's final
2205 callback to assure that all rekey packets go to the network
2206 before quitting the protocol. Affected file silcd/server.c.
2208 * Added silc_client_packet_queue_parse as similar function as
2209 in server to the client library. The affected file is
2210 lib/silcclient/client.c.
2212 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2214 * Splitted silcd/server.c and created silcd/server_util.[ch]
2215 for utility functions.
2217 * Added new socket flag SILC_SF_DISABLED to indicate that the
2218 connection is open but nothing can be sent to or received from
2219 the connection. Affected file lib/silcutil/silsockconn.[ch].
2220 The checking for disabled socket is checked in the low level
2221 silc_socket_write and silc_socket_read functions.
2223 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2225 * Allow only nicknames and channel names that fits into the
2226 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2228 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2230 * When processing JOIN command reply in server check that if
2231 the channel exists in our global list we'll move it the local
2232 list. Affected file silcd/command_reply.c.
2234 * Fixed the check whether client is joined on the channel already
2235 in JOIN command. Affected file lib/silcclient/command.c.
2237 * Fixed the JOIN command reply to check whether the channel
2238 already exists. Affected file lib/silcclient/command_reply.c.
2240 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Added silc_ske_status_string to map the SKE error numbers
2243 to readable strings. The affected files are
2244 lib/silcske/silcske[_status].[ch].
2246 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Do not show the private channels on the WHOIS channel list
2249 as it is not allowed by the protocol. The affected file is
2252 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2254 * Assure that the packet length digged from the actual packet
2255 is something sensible in the silc_packet_decrypt_rest_special
2256 in lib/silccrypt/silcpacket.c.
2258 * Free and NULL the allocated pointer in silc_hmac_alloc if
2259 the HMAC allocation fails. The affected file is
2260 lib/silccrypt/silchmac.c.
2262 * Print the selected security properties to the log files in
2263 the server. Affected file silcd/protocol.c.
2265 * Add SKE's reference counter even if calling the completion
2266 callback manually. Otherwise it goes negative, although it
2267 does not cause any problems. The affected file is
2268 lib/silcske/silcske.c.
2270 * Remove the client entry with short timeout after giving the
2271 KILL command. Affected file lib/silcclient/command.c.
2273 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2274 case all found clients are already disconnected (WHOWAS would
2275 found them) in the server. Affected file silcd/command.c.
2277 * Update the last_receive (time of last data received) to be
2278 updated only when received private or channel message so that
2279 the idle time showed in WHOIS makes more sense.
2281 * Added boolean field `valid' in to the SilcClientEntry in the
2282 client library to indicate whether the entry is valid or not.
2283 This fixes the nickname change bug on channel when changing
2284 the nickname to be same than the old (like nick to Nick) the
2285 nickname formatter doesn't set the new nick anymore to Nick@host.
2286 Affected file lib/silcclient/idlist.[ch].
2288 * Now actually fixed the nickname changing on disconnection.
2289 Added new function silc_change_nick to the Irssi SILC Client.
2290 Affected file irssi/src/silc/core/client_ops.c,
2291 irssi/src/silc/core/silc-nicklist.[ch].
2293 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2295 * Check that the public key exists in the GETKEY command before
2296 trying to encode it. Affected file silcd/command.c.
2298 * Print some notifications on received public keys with GETKEY
2299 command in the Irssi SILC Client. Affected files are
2300 irssi/src/fe-common/silc/module-formats.[ch],
2301 irssi/src/silc/core/client_ops.c.
2303 * Use IDENTIFY command to resolve the server information in the
2304 GETKEY command instead of INFO command. Affected file
2305 lib/silcclient/command.c.
2307 * All command reply functions in the client library now calls
2308 the pending command reply callbacks even if an error has
2309 occurred. The server has done this a long time and now it was
2310 time to move the client library to this as well. Now all
2311 errors can be delivered back to the pending command reply
2312 callbacks if necessary. Affected files are
2313 lib/silcclient/command[_reply].[ch].
2315 * Change the nickname on disconnection back to the username
2316 because in reconnect the server will enforce it to it anyway.
2317 Affected file irssi/src/silc/core/silc-servers.c.
2319 * Fixed a config file parsing bug in the Irssi SILC client.
2320 Affected file irssi/src/silc/core/clientconfig.c.
2322 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2324 * When printing the channel mode on JOIN, verify that the
2325 channel key and channel's HMAC are valid. Affected file
2326 irssi/src/silc/core/client_ops.c.
2328 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2331 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2332 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2334 * Removed channel key rekey task deleting from the function
2335 silc_server_save_channel_key. Affected file silcd/server.c.
2336 Added explicit timeout task context instead that is used to
2337 delete the task if we are registering a new task before the
2338 new task has elapsed.
2340 * When channel key rekey occurs the client library now saves
2341 the old channel key for a short period of time (10 seconds) and
2342 is able to use it in case some is still sending channel
2343 messages encrypted with the old key after the rekey. Affected
2344 file lib/silcclient/[idlist.h|client_channel.c].
2346 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2348 * Added check to the silc_server_new_id_real to not accept
2349 new ID if it is the sender's own ID. Affected file is
2350 silcd/packet_receive.c.
2352 * Assure that we do not announce ourself or the one we've
2353 sending our announcements when we're router and are announcing
2354 servers to our primary router. Affected file silcd/server.c.
2356 * Fixed silc_server_command_identify_check_client to assemble
2357 correct WHOIS packet. It send corrupted WHOIS packet and
2358 caused problem with router to router connections. Affected
2359 file silcd/command.c.
2361 Fixed also silc_server_command_whois_check the same way
2362 as for the IDENTIFY command.
2364 * Added new SilcIDListStatus to the server in the SilcIDListData
2365 structure. The status now includes the current status of
2366 the entry (like registered, resolved etc.). Affected file
2367 silcd/idlist.[ch]. Defined a bunch of different status types
2368 as well. This replaced the old boolean registered field as well.
2370 Added resolve_cmd_ident field to the SilcClientEntry structure
2371 too so that if the entry is for example being resolved so
2372 another command may attach to the same pending command reply
2373 without requiring to resolve the same entry again. This concept
2374 should optimize the WHOIS and the IDENTIFY resolving under
2375 heavy load by taking away unnecessary resolving for entries
2376 that are being resolved already.
2378 Added support for adding multiple pending commands for one
2379 command idenfier. Affected file silcd/command[_reply].[ch].
2381 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2382 before deleting the data. Otherwise the hash table will have
2383 freed data in comparison functions. Affected file is
2384 silcd/command_reply.c.
2386 * Fixed silc_idlist_replace_client_id to add the new entry to
2387 the cache with NULL nickname. Otherwise there will be invalid
2388 memory as the nickname after the nickname is freed. Affected
2389 file silcd/packet_receive.c.
2391 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2392 saved into wrong slots because the previous number of entries
2393 was not taken into account. Affected file silcd/idlist.c.
2394 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2396 * If we are router and we receive JOIN notify to a channel that
2397 does not have any users then notified client is marked as the
2398 channel founder, as it is it. The affected file is
2399 silcd/packet_receive.c
2401 * Added to the extended hash table API's table_del_*ext functions
2402 the destructor as argument too, so that the caller can decide
2403 which destructor to use or whether to use destructor at all.
2404 Affected file lib/silcutil/silchashtable.[ch].
2406 * Fixed ID Cache purging. It actually deleted the entries from
2407 the hash table after the data was freed. The hash table ended
2408 up comparing freed memory. The affected file is
2409 lib/silccore/silcidcache.c.
2411 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Fixed Irssi SILC client's KILL command's HELP syntax.
2415 * The USERS command now resolves the detailed user information
2416 if the userinfo field is missing. Affected file is
2417 lib/silcclient/command_reply.c.
2419 * Do not print error in silc_file_read if the read file does
2420 not exist. Just silently return NULL. Affected file is
2421 lib/silcutil/silcutil.c.
2423 * Fixed the silc_log_output to not wine about NULL filename
2424 and to not create some bogus " " filename. Affected file is
2425 lib/silcutil/silclog.c.
2427 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Fixed various printing bugs on the user interface in the
2430 Irssi SILC Client. Minor changes that were forgotten from
2433 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2435 * Fixed the configure.in.pre and the compilation and distribution
2436 environment to support the new autoconf 2.52. That version is
2437 now required to compile the CVS trunk.
2439 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2442 to generally parse user@fqdn format strings. Affected file
2443 lib/silcutil/silcutil.c.
2445 * Added nickname_format and nickname_force_format fields to the
2446 SilcClientParams structure. The first one defines the format
2447 for the nicknames that the library will enforce if the receives
2448 multiple same nicknames. The second one is boolean value and
2449 can be used to force the library to always enforce the format
2450 to the nicknames regardles whether there are multiple nicknames
2451 or not. This configurable formatting was employed to flexibly
2452 support accessing multiple nicknames from the user interface.
2453 The userinterface can now set the nicknames to what ever format
2454 they prefer. Affected file lib/silcclient/silcapi.h.
2456 Added function silc_client_nickname_format to the file
2457 lib/silcclient/idlist.c. It performs the nickname formatting.
2459 Added new field `hostname´ to the SilcClientEntry context.
2460 It holds the hostname of the client. Affected file is
2461 lib/silcclient/idlist.h.
2463 * Irssi SILC Client sets the nicknames in nick@hostn format.
2464 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2465 irssi/src/silc/core/silc-core.c.
2467 The WHOIS printing now also shows both the real nickname and
2468 the formatted nickname so that user knows how to access the
2469 user if there are multiple same nicknames cached. Affected
2470 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2471 printing formatting too to take the hostname now as a separate
2472 argument. The Affected file is
2473 irssi/src/fe-common/silc/modules-formats.[ch].
2475 * Changed the silc_client_get_clients_local to accept the formatted
2476 nickname as argument. It accepts the real nickname too but the
2477 formatted nickname can be used to find the true entry from
2478 multiple entries. Affected file lib/silcclient/silcapi.h and
2479 lib/silcclient/idlist.c.
2481 * Added nickname_format_parse field to the SilcClientParams.
2482 It is a callback function provided by the application to parse
2483 the nickname out of the formatted nickname string. The library
2484 calls it to get the nickname from the formatted string. Since
2485 the application generally knows better the format of the nickname
2486 string it parses it instead of the library, even though library
2487 encodes the formatted string. If the callback function is not
2488 provided then the library will use the string as is. The
2489 affected file is lib/silcclient/silcapi.h.
2491 * All the nickname strings passed to the client library in
2492 commands are now expected to be formatted nickname strings.
2493 If the command does not support the formatted nickname string
2494 it will assume that the sent string is the actual nickname.
2495 Affected file lib/silcclient/command.c.
2497 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Added public key authentication support to OPER and SILCOPER
2500 commands in the client library. Affected file is
2501 lib/silcclient/command.c.
2503 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2505 * Changed the get_auth_methdod client operation to be asynchronous.
2506 It can be async if the application resolves the authentication
2507 method from the server during the negotiation. Added new
2508 SilcGetAuthMeth completion callback that the application will
2509 call after resolving the authentication method.
2511 Added function silc_client_request_authentication_method that
2512 the application can use to resolve the authentication method
2513 from the server. Added also SilcConnectionAuthRequest callback
2514 that the library will call after the server has replied. The
2515 application can call this function if it does not know the
2516 current authentication method.
2518 Affected files are lib/silcclient/client.c and
2519 lib/silcclient/silcapi.h.
2521 * The Irssi SILC client now automatically resolves the authentication
2522 method incase any configuration information is not present (and
2523 currently there never is). The affected file is
2524 irssi/src/silc/core/client_ops.c.
2526 * Fixed public key authentication from the client library.
2527 Affected file lib/silcclient/protocol.c. Changed also the
2528 protocol specification about the public key authentication in
2529 the connection authentication protocol. The actual data to be
2530 signed is now computed with a hash function before signing.
2532 * Fixed the public key authentication from the server as well.
2533 Affected file silcd/protocol.c.
2535 * Removed the mlock()'s from the memory allocation routines.
2536 Affected file lib/silcutil/silcmemory.c. The ./configure does
2537 not check anymore for the mlock(). Affected file is
2540 * Fixed USERS command in server to allow the execution of the
2541 command for private and secret channels if the client sending
2542 the command is on the channel. Affected file silcd/command.c.
2544 * Fixed silc_client_get_clients_local to return the clients
2545 count correctly. It could return wrong value. Affected file
2546 lib/silcclient/idlist.c.
2548 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2551 types. The assembler optimizations seemed not to like 64-bit
2552 data types. The assmebler optimizations thus are now enabled
2553 also for BSD systems as opposed to only enable them for Linux.
2555 * Do not check for threads at all on BSD systems. Affected
2556 file configure.in.pre.
2558 * Removed -n and -h options from the Irssi SILC Client since
2559 they are not used in silc.
2561 * Fixed the prime generation to assure that the first digit
2562 of the generated random number is not zero since our conversion
2563 routines does not like number strings that starts with zero
2564 digit. If zero digit is seen the random number is regenerated.
2565 This caused some corrupted RSA keys when the zero first digit
2566 was met. Affected file lib/silcmath/silcprimegen.c.
2568 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Fixed WIN32 configuration in the ./configure script.
2571 Fixed to include xti.h on environments that has it.
2572 Patches by Carsten Ilchmann and andrew.
2574 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Changed the silc_id_create_client_id to be collision
2577 resistant. It is now assured that there cannot be created
2578 two same client ID's. I suspect that some weird bugs in
2579 the server were actually caused by duplicate Client IDs.
2580 Affected file silcd/serverid.[ch]. A router receiving
2581 new ID now also assures and informs the sending server
2582 if the ID caused collision.
2584 * Changed the silc_id_create_channel_id to also assure that
2585 there are no collisions.
2587 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2589 * Statement about ignoring the Mutual Authentication flag when
2590 performing rekey with PFS was a bit misleading. It is ignored
2591 if it was set in the initial negotiation, it cannot be even
2592 set in the rekey. Fixed in the ke-auth draft. Started the
2593 new versions of the protocol drafts in the doc/.
2595 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2597 * Fixed a bug in silc_client_command_identify_save when saving
2598 new channel information. The channel name was no duplicated
2599 and caused crash on exit. Affected file is
2600 lib/silcclient/command_reply.c.
2602 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2604 * Fixed the getkey command handling in the server. Send just
2605 empty OK reply to the sender if the key could not be fetched
2606 (but everything else was ok, like the key just was not available).
2607 Changed the public key parameter to optional in the protocol
2608 specs so that empty OK reply can be sent. Affected file
2611 Added a message to Irssi SILC client to tell to user if the
2612 server did not return a public key.
2614 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2616 * Fixed a channel key regeneration bug. It registered new
2617 timeout tasks exponentially until all system resources were
2618 used. Affected file silcd/server.c.
2620 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2622 * Added the SILC Document generator to the scripts/silcdoc.
2623 It can be used to generate the Toolkit Reference Manual out
2624 of the source tree. Internally it will also use the RoboDoc
2625 generator now imported in util/robodoc.
2627 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Added couple of return's in rekey protocol if error orccurred
2630 during the protocol. The execution must be terminated.
2631 Affected file silcd/protocol.c. Also, terminate the protocol
2632 always with timeout.
2634 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2636 * The client's Client ID was created initally from the wrong
2637 nickname (it could have been in format nick@host) in the
2638 silc_server_new_client. Affected file silcd/packet_receive.c
2640 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * Added some SILC_LOG_ERROR's to various error conditions
2643 if client could not be added to ID cache. Affected files
2644 silcd/packet_receive.c and silcd/server.c.
2646 * When client's sock->user_data is freed, NULL also the
2647 client->router and client->connection pointers. Added check
2648 for these pointers being NULL to various places around the
2649 code. Affected file silcd/server.c.
2651 * Added client->data.registered == TRUE checks to various
2652 places around the code to assure that unregistered client's
2653 are not handled when it is not allowed. Affected file
2656 * Added `bool registered' fields to all
2657 silc_idlist_[server|client]_get_* routines to indicate whether
2658 the fetched client needs to be registered or not. Affected
2659 file silcd/idlist.[ch].
2661 * Add your own entry as registered to the ID cache in the
2662 server. Affected file server.c.
2664 * Fixed a bug in silc_server_new_server. The SilcServer was
2665 set as the new server's context instead of SilcServerEntry.
2666 This naturally caused some weird bugs.
2668 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2670 * Do not delete the channel rekey task when adding it
2671 for in silc_server_create_channel_key.
2673 * Changed the silc_server_create_channel_key to return
2674 TRUE or FALSE to indicate the success of the channel key
2677 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2679 * Fixed MSVC++ project files and added missing files to

2688 * Fixed buffer overflow from Irssi SILC Client. Affected
2689 file irssi/src/fe-common/core/themes.c.
2691 * Fixed double free in client library in the file
2692 lib/silcclient/client.c when disconnecting from server.
2694 * Applied double free patch from cras to Irssi SILC client.
2695 Affected files irssi/src/core/[modules/expandos].c
2697 * Fixed the disconnection handling to Irssi SILC Client.
2698 The application must call silc_client_close_connection
2699 in ops->connect client operation in case of failure of
2700 the connection. Affected file is
2701 irssi/src/silc/core/client_ops.c.
2703 * Do not set sock->protocol to NULL in the function
2704 silc_client_close_connection after executing the protocol's
2705 final callback since the sock might not be valid anymore.
2706 Affected file lib/silcclient/client.c.
2708 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2710 * Do not enable SILC_THREADS if the linking with libpthread
2711 did not happen. Affected file configure.in.pre.
2713 * Added notion to protocol specification that server must
2714 verify the sent authentication payload with CMODE when
2715 setting the channel founder key. Implemented it to the
2716 server. Affected file silcd/command.c.
2718 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * Added _EXTRA_DIST SILC distribution variable to the
2721 distributions file. It is used to conditionally add extra
2722 files or directories to the specific distribution. Affected
2723 files ./prepare, Makefile.am.pre and distributions.
2725 Removed the `_' from the start of the distribution names.
2728 * Added README.WIN32 for instructions to compile the Toolkit
2731 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2733 * Fixed a double free in disconnection in the server. Affected
2734 file is silcd/server.c.
2736 * Fixed the lib/silcske/groups.c to work now also with GMP
2737 MP library. The string conversion did not work when using
2738 specific base and the base is indicated in the string as well.
2740 * Created win32/ directory which now includes MSVC++ specific
2741 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2742 It will appear only in the toolkit distribution
2744 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2746 * Changed the key material distribution function in case when
2747 the hash output is too short. The data is now concatenated
2748 a bit differently than it used to. Made the change to the
2749 SKE protocol specification.
2751 * Added better GMP detection to configure.in.pre. A patch
2754 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * Fixed a minor bug in SKE that might cause some problem on
2757 some platforms. Affected file lib/silcske/silcske.c.
2759 * Added the cookie checking for initiator in the SKE. It checks
2760 that the responder returns the sent cookie unmodified. The
2761 affected file is lib/silcske/silcske.c. Added new SKE
2762 error type INVALID_COOKIE that can be sent during the
2763 negotiation. Fixed some memory leaks as well.
2765 * Added the "invalid cookie" error message to Irssi SILC client's
2768 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Added `task_max' field to the SilcClientParams to indicate
2771 the maximum tasks the scheduler can handle. If set to zero,
2772 default values are used. Affected file lib/silcclient/silcapi.h.
2774 * Fixed memory leaks in silc_client_close_connection. Affected
2775 file lib/silcclient/client.c.
2777 * Added silc_client_del_client_entry to client library to free
2778 all memory of given client entry. Affected file is
2779 lib/silcclient/idlist.[ch].
2781 * Added new functions silc_client_del_channel and
2782 silc_client_del_server to delete channel and server entries.
2783 Affected file lib/silcclient/[silcapi.h/idlist.c].
2785 * Removed silc_client_del_client_by_id from silcapi.h.
2787 * Fixed the INFO command to return the server's own info
2788 correctly when querying by Server ID. Affected file is
2791 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2793 * Removed the non-blocking settings in WIN32 code in the
2794 silc_sock_[read/write] and added SleepEx instead. Affected
2795 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2796 of input data is now checked with FIONREAD and ioctlsocket.
2798 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2800 * Call silc_schedule_task_del_by_context in the
2801 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2802 Affected file lib/silccore/silcprotocol.c.
2804 * Call silc_protocol_cancel for active protocols in the
2805 silc_server_close_connection if the funtion
2806 silc_server_free_sock_user_data has not been called.
2807 Affected file silcd/server.c.
2809 * Generic tasks cannot be deleted using the del_by_fd
2810 task deleting function since generic tasks does not match
2811 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2813 * Added a notion to SILCOPER help file that the SILCOPER works
2814 only on router server, not on normal server.
2816 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2818 * Added for WIN32 support for the new scheduler as well.
2819 Affected file lib/silcutil/win32/silcwin32schedule.c.
2821 * Fixed the SHA1 implementation to work on various platforms.
2823 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2825 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2826 API. It is part of the scheduler now. Everything else is
2827 as previously but some functions has changed their names.
2828 Checkout the lib/silcutil/silcschedule.h for the interface.
2829 Updated all applications to use the new interface. Affected
2830 files are lib/silcutil/silcschedule.[ch].
2832 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2834 * Found a bug in the SKE implementation. The HASH value,
2835 specified by the protocol, was not computed correctly. The
2836 public key of the responder was not added to the computation
2837 even though it is mandatory. Affected file lib/silcske/silcske.c.
2838 This unfortunately causes incompatibilities with older
2839 clients and servers.
2841 * Added WIN32 specific network init and uninit functions:
2842 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2843 the Winsock2. Affected file lib/silcutil/silcnet.h and
2844 lib/silcutil/win32/silcwin32net.c.
2846 * Set the socket always to nonblocking mode on WIN32 after
2847 reading data or writing data. Affected file is
2848 lib/silcutil/win32/silcwin32sockconn.c.
2850 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2852 * Fixed various compilation problems under WIN32. Affected
2853 files lib/silcutil/win32/silcwin32thread.c and
2854 lib/silcutil/win32/silcwin32schedule.c.
2856 * Removed all _internal.h #includes from public header
2857 files. Internal headers must never be included from
2860 Removed also the lib/silcske/payload_internal.h file.
2862 * All include files that may be needed (public and some others
2863 included by the public headers) by application developers are
2864 now copied to the ./includes directory. It does not copy any
2865 internal headers. Affected file Makefile.defines.pre and all
2866 Makefile.am's under lib/ and subdirs.
2868 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Do not change the ~/.silc directory's permissions automatically.
2871 Affected file irssi/src/silc/core/clientutil.c.
2873 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Do not cancel the protocol in silc_server_close_connection
2876 it might cause recursion. Now cancelled in the function
2877 silc_server_free_sock_user_data. Affected file silcd/server.c.
2879 * Fixed the silc_server_remove_clients_by_server to regenerate
2880 the channel keys correctly finally. Added also new function
2881 silc_server_remove_clients_channels to actually do it.
2882 Affected file silcd/server.c.
2884 * Fixed the silc_server_new_channel to not crash by giving
2885 wrong router to the new channel. Affected file is
2886 silcd/packet_receive.c.
2888 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2890 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2891 which is given as argument to the silc_client_alloc now.
2892 It can be used to configure the client and set various parameters
2893 that affect the function of the client.
2895 * The USERS command in server did not check whether the channel
2896 is private or secret. Affected file silcd/command.c.
2898 * Added new argument to the USERS command in protocol specification.
2899 The USERS command now can take the channel name as argument
2900 as well. Added support for this in client and server and
2901 updated the protocol specs.
2903 * Completed the GETKEY command in client. It can be now used
2904 to fetch also servers public key not only some clients.
2905 Affected files lib/silcclient/command[_reply].c.
2907 * Added silc_client_get_server to return server entry by the
2908 server name. Affected files lib/silcclient/silcapi.h and
2911 * Redefined the IDENTIFY command in protocol specification to be
2912 more generic. It now can be used to query information about
2913 any entity in the SILC Network, including clients, servers and
2914 channels. The query may be based either the entity's name
2915 or the ID. Added support for this in both client and server.
2917 Affected files silcd/command.c and lib/silcclient/command.c
2918 and command_reply.c.
2920 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2921 the _from_client and _from_server functions. Affected file
2924 * Added silc_client_get_channel_by_id_resolve to the file
2925 lib/silcclient/silcapi.h to resolve channel information by
2926 its ID. Added also silc_client_get_channel_by_id that
2927 does not resolve it from the server.
2929 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Added SilcServerEntry context into the client library
2932 to represent one server. The INFO command now allocates
2933 these to save the resolved server info. For now on the
2934 client library will also keep information about servers,
2935 connected and resolved with INFO.
2937 The INFO command now allocates the SilcServerEntry context
2938 and saves the server info there. The COMMAND_REPLY in
2939 the INFO now returns the parameters to application in
2940 same order as defined in the protocol specification.
2942 The entries are cached in the client->server_cache.
2944 * The INFO command is now issued after received the Client ID
2945 from the server. Affected file lib/silcclient/client.c.
2947 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2948 to the application as the mode changer might be server.
2949 It is guaranteed that NULL is not returned anymore to the
2950 application. Affected file lib/silcclient/client_notify.c.
2952 The ID Type is now also passed to the application so that
2953 it can check whether the returned entry is SilcClientEntry
2956 Added new function silc_client_get_server_by_id to return
2957 the server entry by ID. Affected files are the
2958 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2960 * Do not create the channel in the Irssi SILC Client when issuing
2961 the JOIN command but when received the sucessful JOIN command
2962 reply. Otherwise the channel might get created even though we
2963 could not join it. The Affected file is
2964 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2966 * Fixed a channel joining bug in router. The router must also
2967 check the channel modes, invite and ban lists etc. when serving
2968 the JOIN command sent by normal server. Affected file is
2969 silcd/command.c. The router now resolves the client's
2970 information from the server who sent the JOIN command if it
2971 does not know it, and processes the JOIN command only after
2974 * Changed the SilcCommandCb to take new argument; void *context2.
2975 Affected file lib/silccore/silccommand.h
2977 The second argument in the command callbacks in the server now
2978 includes the SilcServerCommandReplyContext if the command was
2979 called as pending command callback from the command reply.
2980 Otherwise it is NULL. When called as pending the status of the
2981 command reply will be checked and if it was erronous the
2982 error will be sent to the original sender of the command.
2983 This way the client always receives the error messages even
2984 though the server was actually the one who received the error
2985 when it resent the command to router, for example. Affected
2986 files silcd/command[_reply].[ch].
2988 * Fixed sending WHOWAS command's error message to client if
2989 the requested client could not be found. It was missing.
2992 * Changed the CMODE and CUMODE commands reply arguments in the
2993 protocol specification. The Channel ID is now sent in both
2994 of the commands to identify the channel. Implemented this
2995 new feature to the client and server. Affected files
2996 lib/silcclient/command_reply.c and silcd/command.c.
2998 * Made better checks for invite and ban lists in the JOIN
2999 command in server. Affected file silcd/command.c.
3001 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3003 * The server now performs the incoming host IP/DNS lookup
3004 using the silc_socket_host_lookup and thus does not block
3005 the server anymore. Affected file silcd/server.c.
3007 * Completed the multi-thread support for SILC Scheduler in
3008 the lib/silcutil/silcschedule.c.
3010 * Fixed the configure.in.pre to detect the pthread correctly
3013 * Fixed a deadlock in silc_task_queue_wakeup in the file
3014 lib/silcutil/silctask.c.
3016 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3018 * Added new function silc_schedule_wakeup that is used in
3019 multi-threaded environment to wakeup the main thread's
3020 schduler. It needs to be used when a thread adds a new task
3021 or removes a task from task queues. After waking up, the
3022 scheduler will detect the task queue changes. If threads
3023 support is not compiled in this function has no effect.
3024 Implemented the wakeup mechanism to both Unix and WIN32
3025 systems. Affected files are lib/silcutil/silcschedule.[ch],
3026 lib/silcutil/unix/silcunixschedule.c and the
3027 lib/silcutil/win32/silcwin32schedule.c.
3029 * Added new function silc_task_queue_wakeup to wakeup the
3030 scheduler by the specified task queue. Affected file
3031 lib/silcutil/silctask.[ch].
3033 * The silc_socket_host_lookup_start now wakes up the scheduler
3034 after adding the timeout task. Affected file is
3035 lib/silcutil/silcsockconn.c.
3037 * The silc_socket_host_lookup is synchronous now if the threads
3038 support is not compiled in. However, the callback is still
3039 called asyncronously through the scheduler, anyway. Affected
3040 file lib/silcutil/silcsockconn.c.
3042 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3044 * Added new function silc_socket_host_lookup to perform
3045 asynchronous IP and FQDN lookups for the socket connection.
3046 Affected files lib/silcutil/silcsockconn.[ch].
3048 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3050 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3051 that may or may not compile the mutex support in.
3053 Changed the silc_mutex_alloc interface. It allocates the
3054 mutex now to the sent pointer and returns TRUE or FALSE.
3056 Affected file lib/silcutil/silcmutex.h.
3058 * Wrote the SILC Task Queue interface to support multi-threads.
3059 Affected file lib/silcutil/silctask.[ch].
3061 * Wrote the SILC Scheduler to support multi-threads. Affected
3062 file lib/silcutil/silcschedule.c.
3064 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3067 in lib/silcutil/win32/.
3069 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3071 * Defined SILC Mutex API and SILC Thread API and implemented
3072 them for Unix. Affected files are
3073 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3074 lib/silcutil/unix/silcunixmutex.c and
3075 lib/silcutil/unix/silcunixthread.c.
3077 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3079 * Fixed the silc_server_remove_clients_by_server's channel
3080 key re-generation. The hash table handling was incorrect
3081 and would not work with many channels. Affected file is
3084 * Fixed some memory leaks around the server code.
3086 * Rewrote the silc_server_get_users_on_channel to support IPv6
3087 based Client ID's. Affected file silcd/server.c.
3089 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3090 specification. However, a separate document must be written
3091 to define the detailed signing procedure and the payload
3092 associated with the flag. Defined the flag to the
3093 lib/silccore/silcchannel.h as well.
3095 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3097 * Changed the dynamic tables to static size tables in the
3098 lib/silccrypt/silchmac.c.
3100 * Removed GCC dependencies from the code. A patch by cras.
3102 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3104 * Do not show the error "Error receiving packet bla bla"
3105 in server if it really was not an error (-2 means that reading
3106 is pending). Affected file silcd/server.c.
3108 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3110 * Fixed a possible crash in silc_server_remove_clients_by_server
3111 in silcd/server.c. Fixed there also some memory leaks.
3113 * Fixed the silc_idlist_replace_client_id. It could replace
3114 wrong key in the hash table. Affected file silcd/idlist.c.
3116 * Do not check whether there are global users on the channel
3117 if the channel->global_users is FALSE. Affected functions
3118 silc_server_remove_from_one_channel and
3119 silc_server_remove_from_channels in silcd/server.c. Also,
3120 do not check if the removed client is local as we can be
3121 sure that global client was not removed from the channel
3122 and checking for global users is not needed.
3124 * The silc_server_remove_clients_by_server now re-generates
3125 the channel keys correctly for those channels that had
3126 clients removed from them. Affected file silcd/server.c.
3128 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3130 * Found the reason of random crashes in the server. We weren't
3131 ignoring the SIGPIPE signal (which can be sent in write())
3132 and it crashed the server. Affected file silcd/silcd.c.
3134 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3136 * Assure that sock->user_data is not NULL in the function
3137 silc_server_packet_send in silcd/packet_send.c.
3139 * Disconnect the remote connection if it could not be added
3140 to any ID lists in the server. The affected file is
3143 * Check in silc_server_packet_send[_real/dest] that the
3144 socket is not disconnecting and ignore the data if it is.
3145 Affected file silcd/packet_send.c.
3147 * Define inline to __inline on native WIN32 compilation.
3148 Affected file includes/silcwin32.h.
3150 * Added some explicit type casts for inline code since MSVC
3151 require them. Affected files lib/silcutil/silcbuffer.h,
3152 lib/trq/silcdlist.h and lib/trq/silclist.h.
3154 * Print warning in log files from now on if the packet
3155 decryption fails. Affected file silcd/server.c.
3157 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3159 * Changed the `say' client operation's interface to accept
3160 new `type' argument to indicate the type of the message sent
3161 by the library. The application may filter the library's
3162 messages according the type. The affected file is the
3163 lib/silcclient/silcapi.h.
3165 * Added two new functions to lib/silcclient/silcapi.h:
3166 silc_client_del_client and silc_client_del_client_by_id.
3167 Affected file lib/silcclient/idlist.c.
3169 * Moved the clientincludes.h from includes/ to silc/ and
3170 serverincludes.h from includes/ to silcd/.
3172 * The modes for the CMODE and CUMODE are now passed as
3173 uint32 for application with COMMAND_REPLY. The affected
3174 file is lib/silcclient/command_reply.c.
3176 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3178 * /WHOIS without arguments shows client's own information.
3179 Affected file lib/silcclient/command.c.
3181 * Changed PING to not accept any arguments. The specs
3182 says that client can ping only the connected server so
3183 requiring an argument is not needed. Affected file is
3184 lib/silcclient/command.c.
3186 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3188 * Fixed a fatal bug in private message sending and reception
3189 encryption and decryption when using private message keys.
3190 The implementation was incorrect and did not follow the
3191 specification. It causd that some of the message were
3192 lost since it did not use the sending and receiving keys
3193 as the protocol suggests. This has been fixed and will cause
3194 incompatibilities with older clients when sending private
3195 message encrypted with private message keys. Affected files
3196 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3197 and various other in Irssi SILC Client.
3199 Added `responder' boolean argument to the functions
3200 silc_client_add_private_message_key[_ske] to indicate when
3201 the key is added as responder or initiator of the key
3204 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3206 * Removed the silc_ske_check_version function and created
3207 a SilcSKECheckVersion callback. Added also a function
3208 silc_ske_set_callbacks that is now used to set all SKE
3209 callbacks. The callback functions are not given to
3210 the SKE functions anymore, but this function is used to
3213 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3215 * Added `silc_version' argument to the silc_client_alloc
3216 to define the version of the application for the library.
3217 The library will use the version string to compare it
3218 against the remote host's (usually a server) version
3219 string. Affected file lib/silcclient/silcapi.h
3221 * Added the KE protocol context to Key Agreement context
3222 in client library so that we can abort the SKE if it
3223 is in process when we get timeout. Affected file is
3224 lib/silcclient/client_keyagr.c.
3226 * Do not resolve the client ID forever if it returns in the
3227 first time that such client does not exist. This was done
3228 for example with private message. Affected file is
3229 lib/silcclient/client_prvmsg.c.
3231 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3233 * Do not add regex.h for WIN32. The affected file
3234 includes/silcincludes.h.
3236 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3237 not work yet 100%. It generates the DLL's automatically
3238 when compiling with --with-win32 under cygwin.
3240 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3242 * lib/contrib/regex.c is not compiled on WIN32.
3244 * Added silc_net_get_socket_opt function to the
3245 lib/silcutil/silcnet.h.
3247 * Added includes/silcwin32.h for WIN32 specific includes
3250 * Do not use ptime structure or any of the posix process
3251 functions on WIN32 in lib/silccrypt/silrng.c.
3253 * Added silc_gettimeofday to provide generic function
3254 for struct timeval on all platforms. Added the function
3255 to lib/silcutil/silcutil.h.
3257 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3259 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3260 library as they clearly belong there. As a plus side we
3261 can make the actual socket connection routines platform
3264 Added also new generic function silc_socket_read and
3265 silc_socket_write (that used to be silc_packet_[read/write].
3266 The implementation of these are platform specific.
3268 * Added WIN32 specific routines of silc_socket_[read/write]
3269 to lib/silcutil/win32/silcwin32sockconn.c.
3271 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3273 * Added preliminary support for native WIN32 compilation under
3274 cygwin (using the -mno-cygwin option for GCC) to the
3275 ./configure.in.pre. The --with-win32 now prepares the
3276 compilation for native WIN32.
3278 * Rewrote the SILC Scheduler interface in the file
3279 lib/silcutil/silcschedule.h. The scheduler is now context
3280 based and does not have anymore any global static scheduler.
3281 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3282 and created lib/silcutil/win32 directory for WIN32 based
3285 * Added Unix specific network routines to the
3286 lib/silcutil/unix/silcunixnet.c and the old
3287 lib/silcutil/silcnet.c includes now only generic routines.
3289 Added WIN32 specific network routines to the
3290 lib/silcutil/win32/silcwin32net.c.
3292 * Added Unix specific utility functions from the
3293 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3295 * Added WIN32 SILC Scheduler to the file
3296 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3299 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3301 * Do not handle JOIN notify in the server if the target client
3302 is not registered (idata->registered == FALSE). The affected
3303 file is silcd/packet_receive.c.
3305 * Update the nickrec->founder in event_cumode in the Irssi SILC
3306 client. Affected file irssi/src/silc/core/silc-channels.c.
3308 * Fixed the CUMODE_CHANGE notify handling in the server when
3309 server and router are announcing their clients on channels.
3310 Now the mode changes are saved and notified correctly. The
3311 affected file is /silcd/packet_receive.c.
3313 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3314 They really did not replace the cache entry in the ID Cache.
3315 Now they do that. Affected file silcd/idlist.c.
3317 * Fixed the KICK notify handling in the Irssi SILC client to
3318 update the channel records so that the kicked client does not
3319 appear to be on the channel. The affected file is
3320 irssi/src/silc/core/silc-channels.c.
3322 * Always update the conn->current_channel when executing command
3323 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3325 * Fixed the KILL notify handling in Irssi SILC client to remove
3326 the killed client on all channels.
3328 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Fixed the silc_parse_command_line to remove extra spaces
3331 from the start and end of the arguments. Affected file is
3332 lib/silcutil/silcutil.c.
3334 * Cancel and free any active protocol in the function
3335 silc_server_close_connection. Affected file silcd/server.c.
3337 * Cancel and free any active protocol in the function
3338 silc_client_close_connction. Affected file is
3339 lib/silcclient/client.c.
3341 * Do not execute the KILL command for clients that are in
3342 history (ie. they are not in the network). Affected file is
3345 * Fixed KILL notify handling, client does not crash anymore.
3346 Affected file irssi/src/silc/core/silc-channels.c.
3348 * Reduced the default packet buffer size from 2048 to 1024 in
3349 lib/silccore/silcpacket.c.
3351 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3352 counter to the SKE context that is incresed when the SKE library
3353 performs async operation outside the library. If the outside
3354 process frees the SKE context and FREED status will be set
3355 and the library will detect after the sync operation that the
3356 libary is freed. The affected files are
3357 lib/silcske/silcske[_status].[ch].
3359 * Resolve the client entry information in the function
3360 silc_client_channel_message to assure that NULL pointer is not
3361 passed as client entry to the application. */
3363 * Fixed the task timeout calculation to assure that there is
3364 never negative timeouts. The affected file is
3365 lib/silcutil/silcschedule.c.
3367 * Fixed the channel user mode notification sending in server.
3368 It was sent point-to-point to the router (or to server by router)
3369 but it needs to be destined to a channel. The routines now
3370 supports sending the channel user mode notifys to the channels
3371 when announcing clients and channels. Affected files are
3372 silcd/server.c and silcd/packet_receive.c.
3374 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3375 It did not actually replace the old channel entry in the cache.
3376 Affected file lib/silcclient/client_notify.c.
3378 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Fixed a possible crash in silc_packet_send_prepare. It now
3381 assures always that there is enough space in the buffer and
3382 at the tail area of the buffer (for MAC).
3384 Fixed the inbound buffer reallocation in silc_packet_read.
3385 It was old code and did not handle the reallocation correctly.
3388 The affected file is lib/silccore/silcpacket.c.
3390 * Fixed buffer overflow in silc_parse_nickname in the file
3391 lib/silcutil/silcutil.c.
3393 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * make install generates new server keys only if there is not
3398 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3401 Added check that if the NOREPLY is set then we will not send
3402 the away message. This avoids infinite loop of away messages
3403 if both clients are away. The affected file is
3404 lib/silcclient/client_prvmsg.c.
3406 * Fixed client crash if /NICK was given without arguments.
3407 Affected file lib/silcclient/command.c.
3409 * Server does not send the invite list in INVITE command back
3410 to the client if the list was not altered. Added this notion
3411 to the protocol spec as well. Affected file silcd/command.c.
3413 Fixed possible crash in INVITE command by checking the
3414 value of silc_server_get_client_route command.
3416 * Fixed the INVITE notify type handling. The arguments are now
3417 taken in correct order and client does not crash. The affected
3418 file is irssi/src/silc/core/silc-channels.c.
3420 Removed the "Inviting xxx to channel" message from the
3421 client library away and let the application handle it.
3422 Affected file lib/silcclient/command.c. Added that message
3423 to Irssi SILC client's message formats.
3425 * Fixed CMODE command crash in client. It now checks the
3426 amount of arguments correctly and does not crash. The affected
3427 file is lib/silcclient/command.c.
3429 * Do not create new channel automatically in silc_channels_join
3430 but check whether the channel by that name already exists.
3431 Affected file irssi/silc/core/silc-channels.c.
3433 * Do not send the SERVER_SIGNOFF to router if the disconnected
3434 entity was the router. Affected file silcd/server.c.
3436 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3437 SILC client as it was missing from there.
3439 Added the handling of the KICK notify to the Irssi SILC client
3440 as it was missing. Added "you have been kicked" message to
3441 Irssi SILC client's message modules formats.
3443 Added the handing of the KILL notify to the Irssi SILC client
3444 as it was missing. Added the kill message module formats
3447 The affected file is irssi/src/silc/core/silc-channels.c.
3449 * The router did not save the channel mode the server announced.
3450 Affected file silcd/packet_receive.c.
3452 * Fixed a possible crash in INFO command in server. If the
3453 server did not provide the server info it crashed. Affected
3454 file silcd/command.c.
3456 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Fixed the GETKEY command in the server to check also the
3459 global list. Otherwise the GETKEY would not work correctly
3460 in normal SILC server. Affected file silcd/command.c.
3462 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Fixed GETKEY crash, it crashed if the command did not succseed.
3466 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3468 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3469 is now real and not just an macro interface to GMP.
3471 Removed the entire GMP from the source tree and imported new
3472 NSS MPI library instead. Reason for removing GMP is that it is
3473 extremely large and compiles extremely slow. The NSS MPI
3474 is only a few files and compiles in less than 10 seconds.
3475 The speed is also about the same as GMP. The MPI is imported
3476 to lib/silcmath/mpi.
3478 If the system has GMP installed we will still use the GMP.
3479 If it is not then the NSS MPI will be compiled.
3481 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Merged a long nickname (127 characters long) crash bugfix from
3484 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3486 * Merged a freed memory reference bugfix from Irssi CVS tree.
3487 Affected file irssi/src/core/commands.c.
3489 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Added the server's public key sving and verification to the
3492 server when performing the SKE. This was missing and the
3493 remote server's (or router's) public key was accepted without
3494 checking whether we have it previously or trust it at all.
3495 Affected file silcd/protocol.c.
3497 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3499 * Check in the silc_server_timeout_remote if protocol is active
3500 and make sure that the protocol's final callback is called so
3501 that all memory if freed. Affected file silcd/server.c.
3503 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * silc_server_whois_send_reply crashed the server if the nickname
3506 was 127 characters long. Affected file silcd/command.c.
3508 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Added sanity check to the silc_server_new_client. If the hostname
3511 is provided inside username then check that the provided hostname
3512 really is the same as the resolved one. If the hostname was not
3513 resolved then check it from the public key. Affected file is
3514 silcd/packet_receive.c.
3516 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3517 if the server disconnected us and the connection is not valid
3518 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3520 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3521 the library to the lib/silcutil/silcutil.[ch].
3523 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3525 * Close log file after open. Affected file
3526 lib/silcutil/silclog.c.
3528 * Check whether sock == NULL in silc_client_send_packet and return
3529 if it is. Affected file lib/silcclient/silcclient.c.
3531 * Check rec->entry == NULL in the Irssi SILC Client before
3532 sending the channel message. Affecte file is
3533 irssi/src/silc/core/silc-servers.c.
3535 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Merged a splitted window bugfix from Irssi CVS tree. The
3538 affected file is irssi/src/fe-text/textbuffer-view.c.
3540 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3541 It did not print nickname.
3543 * Improved the distributions system a bit.
3545 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3548 irssi/src/fe-text/gui-window.c.
3550 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3551 to in-active server. The affected file is
3552 irssi/src/silc/core/client_ops.c.
3554 * Resolve the client in USERS command reply if the entry does
3555 not have username resolved. The affected file is
3556 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3557 command to WHOIS command to really resolve stuff. The USERS
3558 is not used any more in any critical section so WHOIS can
3559 be used even though it might be slower than IDENTIFY.
3561 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3564 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Changed the protocol API a bit more consistent in the
3567 lib/silccore/silcprotocol.[ch].
3569 * Changed the following headers to ROBODoc format:
3571 lib/silccore/silcpayload.h
3572 lib/silccore/silcprotocol.h
3573 lib/silccore/silcsockconn.h
3575 All core library headers are now formatted.
3577 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * Fixed a bug in Irssi SILC client; do not show that you are
3580 server/router operator if you really are not. Affected file is
3581 irssi/src/silc/core/client_ops.c.
3583 * Renamed silc_command_free_payload to silc_command_payload_free.
3584 Affected file lib/silccore/silccommand.h
3586 * Added silcmath.h to include the prototoypes of various routines
3587 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3590 * Changed the following headers to ROBODoc format:
3592 lib/silccore/silcchannel.h
3593 lib/silccore/silccommand.h
3594 lib/silccore/silcid.h
3595 lib/silccore/silcidcache.h
3596 lib/silccore/silcmode.h
3597 lib/silccore/silcnotify.h
3598 lib/silccore/silcpacket.h
3599 lib/silcmath/silcmath.h
3601 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3603 * Added checking to the server code not to start the server if
3604 ciphers and stuff are not configured properly. Affected files
3605 silcd/serverconfig.[h] and silcd/server.c.
3607 * Changed the layout of the header files of the public interfaces
3608 in the SILC libraries. The new layout supports ROBODoc
3609 documentation tool (and some others) so that it is easy to create
3610 a library reference manual. All the other headers and source
3611 code must still follow the CodingStyle document. Also source
3612 code must not include these ROBODoc stuffs, only the headers.
3613 Furthermore, all public interface headers must now be named
3614 by using `silc' prefix, example: silcapi.h, silccipher.h.
3615 Some files were renamed due to this. All the other headers
3616 must not be used as public interfaces. I will update the
3617 CodingStyle document later. Changed following headers, so far:
3619 lib/silcclient/silcapi.h
3620 lib/silccore/silcauth.h
3621 lib/silccore/silcprivate.h
3622 lib/silccrypt/silcdh.h
3624 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3628 * Removed silc_client_packet_send_flush from the client library
3629 as it is not needed. Affected file lib/silcclient/client.[ch].
3631 * Added printing of message of unresolved authentication method
3632 to the Irssi SILC client. Added it to the module formats.
3633 Removed the same message from the client library.
3635 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * Added new distribution feature, DISTLABEL. Every distribution
3638 can define own preprocessor label that can be used in the
3639 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3640 file distributions, acconfig.h.pre and prepare.
3642 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3644 * Added Makefile.defines_int to include the actual definitions
3645 for Makefile.defines.in. Tested the new distribution system,
3646 created distributions and tested installation.
3648 * Added AWAY message printing to the Irssi SILC client. Added
3649 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3651 * Added SCONNECT command to call the SILC's CONNECT command.
3652 Cannot use CONNECT directly since Irssi uses that internally.
3653 Affected file irssi/src/silc/core/silc-servers.c.
3655 Added ACTION local command. It is same as ME command but takes
3656 the channel as mandatory argument.
3658 Rewrote some of the Irssi's help files to suite for SILC
3661 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Added Makefile.defines[.in] that should for now on be included
3664 in all Makefile.am file in the source tree. That file includes
3665 all common compilation definitions for SILC source tree.
3667 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3669 * Minor changes to the ./prepare script to change the package
3670 name according the distribution name to the configure.in.
3672 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Created new distribution system. Added file `distributions'
3675 that defines all the distributions that can be created out of
3676 the SILC source tree. The ./prepare script now reads that
3677 file to determine how to prepare the distributions. The
3678 first argument to the ./prepare is the name of the distribution
3679 and second is the version of the distribution. If given
3680 without arguments it creates the default (toolkit) distribution
3681 with the default version (defined in ./prepare).
3683 All Makefile.am files that are subject to the distributions
3684 are now named as Makefile.am.pre. These are ./Makefile.am
3685 and lib/Makefile.am. Others may be changed later.
3687 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3689 * Added invite list, ban list, some key management and connection
3690 error message printing to module formats in the Irssi SILC client.
3692 * Added new silc_client_set_away_message to set the away message
3693 that is back to the person who sent private message. The
3694 affected file lib/silcclient/silcapi.h and the
3695 lib/silcclient/client_prvmsg.c.
3697 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3699 * Fixed the private message sending in the Irssi SILC client,
3700 added local command KEY to the Irssi SILC client.
3702 Added key management and key agreement message formats to the
3703 irssi/src/fe-common/silc/module-formats.[ch].
3705 Added USERS (alias WHO) printing, server/router operator
3706 indication and LIST command printing to the module formats.
3708 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3710 * Fixed channel joining notify handling, cumode notify handling
3711 from Irssi SILC client.
3713 * Added SILC specific module-formats to the Irssi SILC client so
3714 that SILC specific message hilighting, colors etc is possible.
3715 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3717 Added channel mode, channel user mode, actions, notices,
3718 whois and whowas printing to the the module-formats.c.
3720 * Fixed a bug in channel deletion in the server. The channel
3721 is not left to the cache even if the channel founder auth mode
3722 is set when there are no users anymore on the channel. Affected
3723 file silcd/server.c.
3725 * The silc_net_localhost now resolves the entire hostname including
3726 the domain name. Affected file lib/silcutil/silcnet.c.
3728 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3730 * Changed the ask_passphrase client operation to be ascynchronous.
3731 It has now a completion callback and a context that the
3732 application must call after it has got the passphrase from
3733 the user. Affected files lib/silcclient/silcapi.h,
3734 lib/silcclient/protocol.c, lib/silcclient/command.c and
3737 Added SilcAskPassphrase callback that the application calls
3738 to deliver the passphrase to the library.
3740 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3741 The public key verification and especially a certificate
3742 verification is asynchronous procedure.
3744 Added new SILC_SKE_STATUS_PENDING status to indicate the
3745 request is pending and a callback will be called to finalize
3748 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3749 indicate that remote end did not send its public key (or
3750 certificate), even though we require it. Added check for this
3751 condition in the SKE. This was a security bug, now fixed.
3753 Defined new SilcSKEVerifyCbCompletion callback that is called
3754 when the verification process is completed.
3756 The affected files lib/silcske/silcske_status.h and
3757 lib/silcske/silcske.[ch].
3759 * Changed the verify_public_key client operation to be async
3760 as well. Defined SilcVerifyPublicKey callback that is used to
3761 indicate the success of the public key verification process.
3763 Changed the server and client to use the new async client
3766 * Changed the Irssi SILC client's internal scheduler to be called
3767 twice as many times as it used to be. As a result the client
3768 should be a bit faster now. Affected file is
3769 irssi/src/silc/core/silc-core.c.
3771 * Added support to Irssi SILC client of asynchronous public key
3772 verification and passphrase inquiry. Affected file is
3773 irssi/src/silc/core/silc-core.c.
3775 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3777 * Do not say "You have left channel %s" in client library.
3778 Moved it to the application. Affected files are
3779 lib/silcclient/command.c and silc/client_ops.c.
3781 * Fixed silc_client_get_clients. Command context was not
3782 duplicated and was freed memory in the callback. Affected
3783 file lib/silcclient/idlist.c.
3785 * Do not say "you are now talking..." on JOIN command in the
3786 client library. The appliation must handle it.
3788 * Do not say ".. changed topic to" in command reply in the
3789 client libary. The application must handle it.
3791 * Fixed TOPIC command sending in the client library.
3793 * Fixed a memory leak in silc_client_command_free in the file
3794 lib/silcclient/command.c.
3796 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Imported a modified version of Irssi client to the source tree.
3799 The Irssi will be used to create a new client called
3800 Irssi SILC. Imported to irssi/.
3802 Added silc_core_init_finish function to the Irssi. Affected
3803 file irssi/configure.in.
3805 A lot changes in the Makefile.ams around the irssi tree.
3807 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Do not rehash if the new size is same as the old size of the
3810 hash table, in the silc_hash_table_rehash*. The affected file
3811 lib/silcutil/silchashtable.c.
3813 * Replaced hash_table_del_by_context calls from the server
3814 (when channel->user_list and client->channels) to the
3815 hash_table_del as it is sufficient and faster.
3817 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3819 * Added silc_hash_table_list, silc_hash_table_get and the
3820 SilcHashTableList structure to provide an alternative way to
3821 traverse the hash table. The affected files are
3822 lib/silcutil/silchashtable.[ch].
3824 * Changed the server's idlist routines to use the hash table
3825 routines to optimize the code.
3827 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Replaced the client entry's `channel' list and channel entry's
3830 `user_list' list to hash tables for optimized lookup. Changed
3831 the code to use the hash table interface around the code.
3832 Affected file lib/silcd/idlist.[ch].
3834 * Added `auto_rehash' boolean argument to the function
3835 silc_hash_table_alloc to indicate whether the hash table should
3836 auto-rehash when it thinks is appropriate time. It will
3837 increase the hash table size if the there is twice as much
3838 entries in the table than the size of the table, and will
3839 decrease the size if there are twice as less entries than
3840 the size of the table.
3842 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3846 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3848 * silc_idcache_purge_by_context deletes the entry now by context
3849 as it is supposed to do. Affected file lib/silccore/idcache.c.
3851 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3852 client is not anymore valid (WHOWAS givens the info) and not
3853 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3855 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Removed the `data' and `data_len' arguments from the ID Cache
3858 interfaces and added `name' argument. ID Cache does not handle
3859 anymore the binary data only a names associated with given ID.
3861 * When hashing a Client ID with silc_hash_id the entire ID is
3862 not hashed anymore, instead only the hash of the Client ID is
3863 hashed. This way we can access the Client ID from the cache
3864 with Client ID but with the hash of the ID (which is a hash of
3865 the nickname) as well without any difference in performance.
3867 Added also silc_idcache_find_by_id_one_ext to do one on one
3868 searching when we have the actual ID. Added also function
3869 silc_hash_client_id_compare. The affected files are
3870 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3872 * When hashing the name associated with a ID it is always done
3873 in lowercase. This way we can access the cache without worrying
3874 about case-sensitivity, even though, for example nicknames are
3877 * Fixed a bug in server with channel message sending. It put
3878 wrong ID type as destination ID. The affected file
3879 silcd/packet_send.c.
3881 * silc_idcache_del_by_context now deletes from all hash tables
3882 by context. Affected file lib/silccore/idcache.c.
3884 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3886 * Changed the client library to use the new ID Cache interface.
3887 Changes around the source tree.
3889 * Added silc_hash_table_rehash_ext to rehash with specific
3890 hash function. Affected file lib/silcutil/silchashtable.[ch].
3892 * Added silc_hash_string_compare to compare two strings in the
3893 hash table. Affected file lib/silcutil/silcutil.[ch].
3895 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3897 * Added new function silc_idcache_del_by_context into the
3898 lib/silccore/idcache.[ch].
3900 * Changed the server's ID list routines to use the new ID Cache
3901 interface. Changes around the source tree.
3903 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3905 * Added silc_hash_table_del[_by_context]_ext functions in to the
3906 lib/silcutil/silchashtable.[ch].
3908 Removed silc_hash_table_find_all* routines and added new
3909 silc_hash_table_find_foreach to replace them.
3911 Added silc_hash_table_replace_ext function as extended
3912 replacing function. Separated the simple hash table interface
3913 from the extended hash table interface in the file
3914 lib/silcutil/silchashtable.h.
3916 * Fixed minor bugs and changed it to use some of the new
3917 hash table functions in lib/silccore/idcache.c
3919 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Added new function silc_hash_table_find_all to return all keys
3922 in the hash table by the specified key. As the hash table is
3923 collision resistant it also makes it possible to have several
3924 duplicate keys in the hash table. This function may be used to
3925 find all of the keys from the hash.
3927 Added user_context arguments to the SilcHashFunction,
3928 SilcHashCompare and SilcHashDestructor to deliver user specified
3931 Added new fuctions silc_hash_table_find[_all]_ext to do
3932 extended lookup with specified hash and compare functions and
3933 specified user contexts.
3935 Added new function silc_hash_table_add_ext to add the key
3936 with specified hash function and user context.
3938 Added new function silc_hash_table_foreach to traverse all
3939 entrys in the hash table. Added SilcHashForeach callback
3942 Added new function silc_hash_table_del_by_context to delete
3943 the entry only if the context associated with the key matches.
3945 Affected files are lib/silcutil/silchashtable.[ch].
3947 * Removed silc_hash_[server/client/channel]_id and added just
3948 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3949 silc_hash_id_compare to compare two ID's using as the hash table
3950 comparison function. Added also silc_hash_data to hash
3951 binary data and silc_hash_data_compare to compare it.
3953 * Removed silc_idlist_find_client_by_hash as it is not needed
3954 anymore. Affected file silcd/idlist.[ch].
3956 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3957 to use internally the SilcHashTable. The new ID Cache is a lot
3958 faster than the old one. Some of the ID Cache interface was also
3959 rewritten and obsolete and stupid functions were removed.
3961 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3963 * Added entry_count field to the SilcHashTable to keep the number
3964 of the entries in the table. Implemented the function
3965 silc_hash_table_rehash. Added new function
3966 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3968 Fixed a minor bug in silc_hash_table_free.
3970 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3971 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3972 into the lib/silcutil/silcutil.[ch].
3974 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Implemented a collision resistant hash table into the
3977 lib/silcutil/silchashtable[ch]. See the header and the source
3978 for the SilcHashTable API.
3980 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3982 * Merged dotconf version 1.0.2 into lib/dotconf.
3984 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3986 * Do not compile anything in lib/silcsim/* if the SIM support
3987 is not enabled. The tree should now compile without problems
3990 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * Compiled the SILC under cygwin. Compiled and tested briefly
3993 without problems. More tests needed. The SIMs didn't compile
3996 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3998 * Fixed possible crash in silc_get_username in the
3999 lib/silcutil/silcutil.c.
4001 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Fixed a va_arg in silc/client_ops.c.
4005 * Oops, RC5 routines were named AES and caused some problems
4006 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4008 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4010 * Added new SilcIDIP structure into the lib/silccore/id.h and
4011 replaced the old `ip' fields from all SILC ID's to that type.
4012 This is a step towards IPv6 support.
4014 The silc_id_get_len takes now the ID as an extra argument.
4015 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4016 both IPv4 and IPv6 based ID's.
4018 The affected files are lib/silccore/id.[ch] and other files
4019 around the tree using these routines.
4021 * Removed the ID length arguments in server from various
4022 silc_server_send_notify_* routines -> they are not needed
4025 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Fixed memory leak in silc_encode_pem_file in the file
4028 lib/silcutil/silcutil.c.
4030 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Check minor version as well in the SKE. Affected files are
4033 silcd/protocol.c and lib/silcclient/protocol.c.
4035 * Added --identifier option to the server so that an identifier
4036 can be when creating the public key for the server. Affected
4037 file is silcd/silcd.c.
4039 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4040 lib/silccrypt/silcpkcs.c.
4042 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Register default ciphers and stuff when using -C option with
4045 the server. Affected file sildc/silcd.c.
4047 * Put back the servers public key filename format, it is better
4048 than the new one. For now, the client keys are saved with the
4049 new filename format. The affected file silc/client_ops.c.
4051 * Implemented the Cipher API for the rest of the ciphers that
4052 did not implement it or implemented it the wrong way.
4054 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Register default ciphers and stuff when using the -S option
4057 in the client. Affected file silc/silc.c. Same also when
4058 creating new key pair with -C option.
4060 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Fixed the silc_verify_public_key client operation function to
4063 save the public keys differently. The fingerprint is now
4064 used as filename and not the hostname. This way also the
4065 client keys are saved uniquely and not with hostnames. The
4066 affected file is silc/client_ops.c.
4068 * Trimmed the silc_hash_fingerprint function to remove extra
4069 whitespaces from the end of the fingerprint. The affected
4070 file is lib/silccrypt/silchash.c.
4074 * Added silc_cipher_register_default function to register all
4075 default ciphers. It can be used when configuration files
4076 does not exist and the application does not want any specific
4077 ciphers in any specific order.
4079 The SilcDList is now used as silc_cipher_list dynamically
4080 allocated cipher list. Removed the static list all together
4081 and now all ciphers must be allocated to the dynamic list.
4082 The silc_cipher_alloc routine was changed to check only the
4085 All silc_cipher_* routines that used to return int returns
4088 The affected files lib/silccrypt/silccrypt.[ch].
4090 * The same thing was done to silc_hash_* as for silc_cipher_*
4091 routines. Affected files lib/silccrypt/silchash.[ch].
4093 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4094 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4095 Added also silc_pkcs_[un]register[_default] functions.
4096 Removed the data_context from the PKCS API.
4098 * Added silc_hmac_register_default function to register default
4099 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4100 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4101 to unregister all hmacs at once.
4103 * Register the default ciphers, hash functions, PKCSs and HMACs
4104 if client's configuration file does not exist. The affected
4107 * The client did not load the hash functions from the SIM
4108 modules at all. Added support for this. Affected file is
4109 silc/clientconfig.c.
4111 * When decoding public key with silc_pkcs_public_key_decode, check
4112 the supported algorithm only if PKCS are registered. Affected
4113 file lib/silccrypt/silcpkcs.c. The same was done with the
4114 silc_pkcs_private_key_decode.
4116 * Fixed the SILC List routines to keep the list always in order.
4117 It used to change the list's order when traversing the list but
4118 not it preserves the order. Affected file lib/trq/silclist.h.
4120 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4122 * Added the client library to use the SilcSocketConnection's
4123 reference counter (by silc_socket_dup) to prevent the bug that
4124 the socket object may be freed underneath async operation.
4126 * The name resolv library checking fixes in the configure.in.pre.
4129 * Created new version of the protocol drafts for future
4130 development. The -03 drafts are the ones that will be changed
4131 in the trunk now and the -02 will remain as they are.
4133 * Send list of CUMODE notifys to the router when announcing
4134 the channel users to the router. Affected file silcd/server.c.
4135 If the router receiving channel founder CUMODE for a channel
4136 that already has channel founder it will send CUMODE notify
4137 to the sender to remove the channel founder rights from the
4138 announced client. Affected file silcd/packet_receive.c.
4140 * The CUMODE notify may now use Server ID as well as the entity
4141 who changes the mode. Updated protocool specs.
4143 * Updated INSTALL and README files.
4145 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * New web pages in the http://silc.pspt.fi. The pages was
4152 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4154 * Implemented the [DenyConnectin] config section in the server.
4155 Added silc_server_config_denied_conn to check whether incoming
4156 connection is denied. Affected file silcd/serverconfig.[ch].
4158 * Do not check the ports when checking the incoming configuration
4159 data if the port is 0, meaning any. Affected file is
4160 silcd/serverconfig.c.
4162 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Fixed buffer overflow in silc_string_compare in the file
4165 lib/silcutil/silcutil.c.
4167 * Fixed double free in silc_server_command_leave in the file
4170 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Fixed the version checking in the server. Affected file is
4175 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Fixed the configuration data fetching when accepting new
4178 connections in the server. Affected file silcd/server.c.
4180 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4182 * Added `sender_entry' argument to the function
4183 silc_server_packet_relay_to_channel so that we can check
4184 whether some destination actually belongs to the same route
4185 the sender belongs (ie, we must not resend the packet to the
4186 sender). Affected file silcd/packet_send.[ch].
4188 * Added `servername' field to the SilcClientEntry in the server
4189 to hold the name of the server where client is from. Affected
4190 file is silcd/idlist.h.
4192 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Moved the channel message encrypting in the router betwen
4195 router connections from silc_server_channel_message to the
4196 silc_server_packet_relay_to_channel since we want to check
4197 whether we have anybody channel before encrypting anything.
4198 Affected files silcd/packet_[receive/send].c.
4200 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Fixed the [AdminConnection] server config section to support
4203 multiple entries. Affected file silcd/serverconfig.c.
4205 * Added support into the server to check the validity of the
4206 incoming connection before executing any KE or authentication
4209 * The connection configuration is now saved to the KE and
4210 connection auth protocol contexts and not fetched anymore in
4211 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4213 * The local hosts listenning address and port is also resolved
4214 now when starting the server. We want to have the socket object
4215 to include the real address and port for the listener. Added
4216 new function silc_net_check_local_by_sock into the files
4217 lib/silcutil/silcnet.[ch].
4219 * Fixed a broadcast bug in server -> do not broadcast if we
4222 * Fixed a routing bug. Do not route broadcast packets ever.
4223 Broadcast packets must be processed always and not routed since
4224 they may be destined to some other host than yourself and thus
4225 would get routed without no good reason. Affected file is
4228 * Added function silc_server_config_is_primary_route to check
4229 whether primary router connection has been configured (a router
4230 configuration that we are initiating). If there is not, we
4231 will assume that there is only two routers in the SILC network
4232 and we will use the incoming router connection as our primary
4233 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4235 * Changed the order of the broadcasting. Broadcast _after_ the
4236 packet has been processed not before. Affected file is
4239 * Fixed a [ClientConnection] parsing bug. The port was never
4240 parsed correctly thus resulting to port 0. Affected file
4241 silcd/serverconfig.c.
4243 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4244 argument and did not set the broadcast packet flag. Affected
4245 file silcd/packet_send.c. Fixed same bug in the function
4246 silc_server_send_notify as well.
4248 * If we receive NEW_ID packet for our own ID in the server, ignore
4251 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4255 * Removed the nickname from the Private Message Payload.
4256 Updated the code and the protocol specs.
4258 * Updated protocol specs for submitting to the IETF.
4260 * Tweaked the Random Number Generator a bit. Affected file
4261 lib/silccrypt/silcrng.c. Exported a new function
4262 silc_rng_[global]_add_noise which can be used to add more
4265 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Do not parse packets with different timeout when protocol
4268 is active -> may cause problem with rekey. Affected file
4271 * When server receives signoff notify it must not create
4272 new channel key if the client is on any channels since the
4273 sender of the signoff notify will create it.
4275 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4277 * Added printing of error messages during SKE protocol from the
4278 failure packet sent by server during SKE. Affected file
4281 * Removed the client's failure_callback handling with timeout
4282 and handle it immediately when received.
4284 * The SKE library returned wrong type in SUCCESS and FAILURE
4285 packets. They must be 32 bit MSB not 16 bit MSB.
4287 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Ok, rewrote the logic of the re-key and now it seems to work.
4290 I tested it on high traffic with frequent re-keys without
4291 problems. Added hmac_receive (and renamed hmac to hmac_send)
4292 in SilcClientConnection in lib/silcclient/client.h and
4293 in SilcIDListData in silcd/idlist.h. Also, removed the
4294 SilcPacketParserContext's cipher and hmac fields as they are
4295 not needed anymore and actually caused some problems when
4296 the ciphers and hmac's changed underneath the packet parser.
4298 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * If re-key protocol is active then process the incoming packets
4301 synchronously since we must assure that icoming packets encrypted
4302 with the old key is processed before the new keys is set to
4303 use. This is true other packets than for REKEY packets.
4304 Affected file silcd/server.c. The same was done to client library
4305 as well, affected file lib/silcclient/client.c.
4307 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * Fixed bug in client and server to accept the force send if
4310 the packet is send from silc_[server/client]_packet_process
4311 function. Otherwise the packets are never delivered, oops.
4313 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4315 * Disable force sending of packets when REKEY protocol is active.
4316 We must assure that no packet is sent directly when rekey is
4317 performed. All packets must be sent through packet queue.
4318 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4319 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4320 function is silc_[server/client]_packet_send_real to check
4323 * Replaced the SIM paths from example config files to
4324 /usr/local/modules. Also, make install creates now
4325 /usr/local/silc/logs directory to hold all the SILC server
4328 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Made the configure.in.pre work on Solaris. Patch by salo.
4332 * Made all ciphers compatible with non-x86 machines. Defined
4333 CBC mode macros into lib/silccrypt/ciphers_def.h.
4335 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Fixed the make install.
4339 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * When MAC computation fails the silc_packet_decrypt returned 0
4342 even though it was supposed to return -1. Fixed this. The
4343 affected file is lib/silccore/silcpacket.c.
4345 * Do not replace the config files in /etc/silc (in make install)
4346 if they already exist. Affected file ./Makefile.am.
4348 * Do not send re-key packets immediately but through packet queue.
4349 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4351 * Changed silc_net_check_host_by_sock to return FALSE if the
4352 IP/DNS could not be resolved. Though, it returns the IP address
4353 now even if it could not resolve it (but returns also FALSE).
4354 Affected file lib/silcutil/silcnet.[ch].
4356 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Added silc_pkcs_decode_identifier to decode the public key's
4359 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4360 Added also silc_pkcs_free_identifier. Added also new context
4361 SilcPublicKeyIdentifier.
4363 * Added -S option to the silc client. It is used to dump the
4364 contents of the specified public key file.
4366 * Changed the PKCS api to return the public key length when
4367 setting the public key.
4369 * Fixed a fatal bug in the public and private key file loading.
4370 Affected file lib/silccrypt/silcpkcs.c.
4372 * Execute the packet parsing for client with zero (0) timeout
4373 if the protocol is active. Affected file silcd/server.c.
4375 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Made the key generation options to the silcd program. Added
4378 -C option, equivalent to client's option.
4380 * Added new [ServerKeys] config section to the server. It
4381 configures the server's public and private key.
4383 * Defined generic Public Key Payload into the protocol
4384 specification to send specific type of public keys and
4387 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4388 public key or certificate.
4390 * Implemented the GETKEY command to the server and to the
4391 client library and on user interface.
4393 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Made preliminary `make install' work.
4397 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * Added SilcServerRekey context into silcd/idlist.h.
4401 * Added the PFS support as defined in the specification to the
4402 SKE protocol. Affected files lib/silcske/*.c.
4404 * Added `ske_group' field to the SilcServerRekey context to hold
4405 the number of the SKE group that is used with PFS in re-key.
4406 Affected file silcd/idlist.h.
4408 * Added PFS re-key support to the server. Affected file is
4411 * Added silc_protocol_cancel to cancel execution of the next
4412 state of the protocol. Affected file is
4413 lib/silccore/silcprotocol.[ch].
4415 * Added the re-key support with and without PFS to the client
4416 library. Re-key is performed once in an hour, by default.
4418 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4419 Added silc_client_rekey_callback and silc_client_rekey_final.
4420 Affected files are lib/silcclient/protocol.[ch] and
4421 lib/silcclient/client.[ch].
4423 * Removed the `hmac_key' and `hmac_key_len' fields from the
4424 SilcClientConnection structure; not needed. Affected file is
4425 lib/silcclient/client.h.
4429 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Do not ask whether user wants to use the negotiated private key
4432 for private messages, just use it. Affected file is
4433 silc/local_command.c.
4435 * Added `send_enc_key' and `enc_key_len' fields to the
4436 SilcIDListData structure since they are needed in the re-key
4437 phase. Affected file is silcd/idlist.[ch].
4439 * Implemented the simple re-key protocol into the server.
4440 Affected files silcd/server.c and silcd/protocol.[ch]. The
4441 re-key will be performed once in an hour, by default.
4443 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4444 Added silc_server_rekey, silc_server_rekey_callback and
4445 silc_server_rekey_final.
4447 * Removed Tunneled flag from the protocol. Updated the code
4448 and the specifications.
4450 * Adde `pfs' field to the SilcIDListData to indicate whether
4451 the PFS is to be performed in the re-key. Affected file is
4454 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4457 int64 of at least the xintXX size. If void * is less that 4
4458 bytes uint32 * will be used. Defined bool as boolean.
4460 * Changed _ALL_ unsigned long and unsigned int to uint32,
4461 unsgined short to uint16 in the source tree.
4463 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4464 not handle clients that has entry->data.registered == FALSE.
4465 They are not in the network anymore. Affected file is
4468 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Implemented the sending of the SERVER_SIGNOFF notify in the
4471 server. Affected file is silcd/server.c.
4473 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4474 Added also silc_notify_payload_encode_args into the
4475 lib/silccore/silcnotify.[ch].
4477 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4478 Affected file silcd/packet_receive.c.
4480 * Implemented the SERVER_SIGNOFF notify handling in the client
4481 library. Affected file lib/silcclient/client_notify.c. Also,
4482 implemnted the printing of the SERVER_SIGNOFF info to the
4483 application. Affected file silc/client_ops.c.
4485 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4486 if the deleting was successful. Affected file silcd/idlist.[ch].
4488 * Added support for public key authentication in the connection
4489 authentication protocol in the client library. Affected file
4490 lib/silcclient/protocol.c.
4492 * Changed the server's silc_idlist_get_clients_by_* interface
4493 to support already allocated array so that new entries may be
4494 added to pre-allocated array. Affected file silcd/idlist.[ch].
4495 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4496 and command replies.
4498 * All command reply functions in the server now calls the
4499 pending command callback even if error occured. This way the
4500 error will be delivered to the client as well. Affected files
4501 silcd/command.c and silcd/command_reply.c.
4503 * Fixed INFO command to return local server's info if no server
4504 was provided. Affected file lib/silcclient/command.c.
4506 * Removed RESTART command for good. Updated the code and the
4509 * Rewrote parts of the task system. It is a bit simpler now.
4510 Removed unsued task priorities. The affected files are
4511 lib/silcutil/silctask.[ch].
4513 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Moved the USERS printing from the library to the application.
4516 Affected files lib/silcclient/command.c and silc/client_ops.c.
4518 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Added channel key re-key support. The re-key is perfomed
4523 only by the router and is done once in an hour. Added `rekey'
4524 field to the SilcChannelEntry in the server. Affected files
4525 silcd/server.c and silcd/idlist.h.
4527 * Added silc_task_unregister_by_context into the file
4528 lib/silcutil/silctask.[ch].
4530 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Added SILC_UMODE_GONE mode to indicate when the client is not
4533 present in the SILC network. Added also support to the local
4534 command AWAY that will set this mode. Added support of showing
4535 "xxx is gone" in WHOIS command. The USERS command shows the
4536 gone status as well.
4538 * Fixed setting server and router operator privileges in the
4539 server's UMODE command. Affected file silcd/command.c.
4541 * Merged the SKE KE1 and KE2 payloads into one payload. The
4542 new KE payload is equivalent to the old KE2 payload.
4544 Cleaned up the SKE Start Payload parsing. It now uses the
4545 simple buffer unformatting to do the parsing. A lot faster
4548 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4549 to the SKE that is used to indicate whether both of the SKE
4550 parties should perform authentication. By default only the
4551 responder performs authentication. By setting this flag also
4552 the initiator must do authentication. By default it is unset
4553 since in normal SKE case, client to server connection, only
4554 the responder should do authentication. When doing SKE between
4555 two clients both should perform authentication. Updated the
4556 code and the protocol specs.
4558 * A little fix to IDENTIFY command in the server. Search the
4559 client first by hash not nickname. Affected file is
4562 * Fixed the silc_client_close_connection to support closing
4563 the client to client connections wihtout deleting too much
4564 data. Affected file lib/silcclient/client.c.
4566 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4567 are received if protocol used to be active but is not anymore
4568 the application would crash due to NULL pointer dereference.
4569 Affected files silcd/server.c and lib/silcclient/client.c.
4571 * Added `hash' field to the SilcClientConnection to include
4572 the hash function negotiated in the SKE protocol.
4574 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4575 to set the channel founder authentication data. A client can
4576 claim the founder rights later by providing the authentication
4577 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4578 This way the channel founder can regain the channel founder
4579 privileges even it is left the channel. This works only on
4580 local server and the client must be connected to the same
4581 server to be able to regain the founder rights. Updated the
4582 protocol specs accordingly.
4584 Added support to the CMODE command in the client to set the
4585 founder auth data. Read the README to see how to set it.
4587 Added support to the CUMODE command to claim the founder
4588 rights. Read the README to see how to do it.
4590 Added support for the founder authentication to the Channel
4591 Entry in the server. Affected file silcd/idlist.h.
4593 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4594 server's CMODE command. Affected file silcd/command.c.
4596 * Added the following new functions into lib/silccore/silcauth.[ch]:
4597 silc_auth_get_method and silc_auth_get_data.
4599 * The server now saves the remote hosts public key to the
4600 SilcIDListData pointer. Affected file silcd/protocol.c.
4602 * The normal server now does not remove the channel entry from
4603 the cache if the founder authentication data is set. It used
4604 to remove it if the founder was the last one on the channel on
4605 the server and left the channel. The auth data is saved and
4606 if the channel is re-joined later the old entry is used with
4607 the old auth data. Affected files silcd/command_reply.c and
4610 * Removed the `pkcs' field from the SilcIDListData structure
4611 in the server; it is not used. Affected file silcd/idlist.h.
4613 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4615 * Fixed packet processing on slow links. Partial packets were
4616 never re-processed because the incoming data buffer was cleared
4617 by the application. Application must not directly clear the
4618 sock->inbuf, the packet processing routines handle it. Fixed
4619 this in client library and in server.
4621 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Fixed the WHOIS and IDENTIFY send reply function to really
4624 check whether to send list or just one entry. Affected file
4627 * Cleaned up the LEAVE command's channel key distribution. The
4628 affected file silcd/command.c.
4630 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4631 can enforce the channel mode as well. In that case the ID
4632 includes the ID of the server. The code now enforces the
4633 mode change if the router have different mode than the server.
4635 * The notify client operation with CMODE_CHANGE notify can now
4636 return NULL client_entry pointer if the CMODE was not changed
4637 by client. Application must check for this.
4639 * Added <Server ID> argument to INFO command to support server
4640 info fetching by Server ID.
4642 * Added silc_server_announce_get_channel_users to get assembled
4643 packets of channel users of the specified channel. Affected
4644 file silcd/server.[ch].
4646 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4647 was freed underneath the ID Cache.
4649 * Re-announce clients when the server received CHANNEL_CHANGE
4650 notify from the router. Affected file silcd/packet_send.c.
4652 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4655 crashed since it did not handle the fact that there is no cipher
4656 called "3" and didn't check the error condition. Now fixed.
4658 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4659 flag. It can be used to send message requests.
4661 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Implemented the RESTART command in the client.
4665 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4666 notice type messages. Added notice printing to the user
4669 * The channel keys are not re-generated if the channel's mode
4670 is PRIVKEY, ie private key on the channel exists. Affected
4671 files silcd/server.c and silcd/command.c.
4673 * Fixed a little bug in channel message delivery when channel
4674 private keys are set in the server. Affected file is
4675 silcd/packet_send.c.
4677 * Changed the setting on channel->on_channel = TRUE from the
4678 silc_client_save_channel_key to the JOIN command reply. The
4679 key payload is not received if the private channel key is set.
4680 Affected file lib/silcclient/command_reply.c and the
4681 lib/silcclient/client_channel.c.
4683 * When the CMODE_CHANGE notify is sent and the channel private
4684 key mode is removed the channel key must be re-generated in
4685 other cells as well. Added this support for the router in the
4686 silcd/packet_receive.c.
4688 * Added new local command NOTICE to send notice message on
4689 channel. Affected file silc/local_command.[ch].
4691 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Added new local command ME to the client. It is used to send
4694 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4695 some action. Affected file silc/local_command.[ch].
4697 * Changed channel_message and private_message client operations
4698 to deliver the message flags to the application. Added also
4699 the `flags' arguments to the silc_client_send_channel_message
4700 and silc_client_send_private_message functions. Affected file
4703 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * Redefined the Private Message Payload to support private message
4706 keys and to support the new private message flags. Updated
4707 the protocol specs. Flags makes it possible to have for example
4708 CTCP style messages.
4710 * Added new type SilcPrivateMessagePayload and defined an API
4711 for it in the lib/silcclient/silcprivate.[ch].
4713 * Tested private message private keys successfully. Tested the
4714 private message key set, unset and list commands with the new
4717 * Redefined the Channel Message Payload to include the channel
4718 message flags (equal with private message flags) to support
4719 for example CTCP style messages.
4721 * Defined some of the message (for channel and private message)
4722 flags. Updated the protocol specs and added the flags to the
4723 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4725 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * Added SilcKeyAgreementStatus type to the key agreement routines
4728 to indicate the current status and error if one occured.
4729 The status types are defined in the lib/silcclient/silcapi.h.
4731 * Added new local command KEY that is used to set and unset private
4732 keys for channels, set and unset private keys for private messages
4733 with remote clients and to send key agreement requests and
4734 negotiate the key agreement protocol with remote client. The
4735 key agreement is supported only to negotiate private message keys,
4736 it currently cannot be used to negotiate private keys for channels,
4737 as it is not convenient for that purpose.
4739 * Fixed a minor pending callback setting bug in the function
4740 silc_client_get_client_by_id_resolve, now the function works.
4741 Affected file lib/silcclient/idlist.c.
4743 * Added function silc_net_get_local_port to get local bound
4744 port by socket. Added to lib/silcutil/silcnet.[ch].
4746 * Added `sockets' and `sockets_count' fields to the SilcClient
4747 object. They hold the sockets of the listenning sockets in
4748 the client. Listenning sockets may be for example the key
4749 agreement server. Affected file lib/silcclient/client.[ch].
4750 Added functions the silc_client_add_socket and the
4751 silc_client_del_socket. They are exported to the application
4754 * Added ~./silc/clientkeys to support other client's public keys.
4756 * Renamed verify_server_key client operation to verify_public_key
4757 and added one argument to indicate the type of the connection
4758 (server, client etc.).
4760 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4762 * Added silc_server_connection_auth_request to handle the
4763 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4764 silcd/packet_receive.[ch].
4766 * Added silc_server_send_connection_auth_request into the
4767 silcd/packet_send.c to send the connection auth request packet.
4769 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4772 * Fixed the public key authentication in responder side in the
4773 server. The `auth_data' pointer includes the SilcPublicKey
4774 not the path to the public key. Affected file silcd/protocol.c.
4776 * Implemented the public key authentication in the initiator side
4777 in the server. Affected file silcd/protocol.c.
4779 * Removed the [RedirectClient] config section from the server
4780 configuration. Is not needed and I don't want to implement it.
4782 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Cleaned up the CMODE command in the server. It now works
4785 correctly and supports all the modes defined in the protocol.
4786 Affected file is silcd/command.c.
4788 * Added `hmac_name' field to the SilcChannelEntry in the server
4789 to hold the default HMAC of the channel. It can be set when
4790 creating the channel (with JOIN command). Affected files
4793 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4794 type to indicate the change of the current cipher and hmac
4795 on the channel. Client can safely ignore the <cipher> argument
4796 (if it chooses to do so) since the CHANNEL_KEY packet will
4797 force the channel key change anyway. The <hmac> argument is
4798 important since the client is responsible of setting the new
4799 HMAC and the hmac key into use.
4801 * Fixed the CMODE command in the client library as well.
4803 * Tested CMODE command in router environment successfully.
4805 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Show the version of the remote client (or server) when connecting
4808 to the server. It is logged to the log file. Affected file
4809 is silcd/protocol.c.
4811 * Fixed the KILLED notify handling in the client library. The
4812 client must be removed from all channels when receiving the
4815 Also, do not remove the client entry when giving the KILL
4816 command but when the KILLED notify is received.
4818 * Removed silc_idlist_find_client_by_nickname from the server.
4819 Not needed anymore. Affected files silcd/idlist.[ch].
4821 * Implemented the CHANNEL_CHANGE notify type handling to the
4822 server. Affected file silcd/server.c.
4826 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Added silc_server_send_notify_invite to send the INVITE
4829 notify between routers.
4831 * Implemented the INVITE command correctly to the server.
4833 * Implemented the INVITE notify type handling in the server.
4835 * Implemented the INVITE command to the client library and on the
4838 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Added function silc_server_get_client_resolve to find the
4841 client entry by ID from all ID lists and then resolve it
4842 (using WHOIS) if it cannot be found. Affected file is
4845 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Implemented the BAN command to the client library.
4849 * The JOIN command in the server now checks the invite list
4852 * Changed the silc_command_reply_payload_encode_va and the
4853 silc_command_payload_encode_va to support that if argument is
4854 NULL it ignores and checks the next argument. Affected file
4855 lib/silccore/silccommand.c.
4857 * Added silc_server_send_notify_ban to send the BAN notify
4858 type between routers.
4860 * Chaned the silc_notify_payload_encode to support that if
4861 argument is NULL it ignores and checks the next argument.
4862 Affected file lib/silccore/silcnotify.c.
4864 * Tested ban lists in router environment successfully.
4866 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Implemented BAN command to the server, in silcd/command.[ch].
4870 * Removed the BAN and INVITE_LIST modes from the CMODE command
4873 * Added function silc_string_match to regex match two strings.
4874 Affected files lib/silcutil/silcutil.[ch].
4876 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Redefined parts of the SilcChannelEntry in the server to support
4879 the new ban and invite lists.
4881 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Redefined the INVITE command. The same command can be used to
4884 invite individuals to the channel but also to manage the invite
4885 list of the channel (to add to and remove from the invite list).
4886 Updated the protocol specs.
4888 * Added new command SILC_COMMAND_BAN that can be used to manage
4889 the ban list of the channel. Updated the protocol specs.
4891 * Removed the channel modes: the SILC_CMODE_BAN and the
4892 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4893 in the CMODE command. The equivalent features are now available
4894 using INVITE and BAN commands. Updated the protocol specs.
4896 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4897 in the network about change in the current ban list. The notify
4898 type is not used by the client.
4900 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4901 support the invite lists.
4903 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4905 * Added new function silc_string_regexify that converts string
4906 including wildcard characters into regex string that can
4907 be used by the GNU regex library. Added into the file
4908 lib/silcutil/silcutil.[ch].
4910 Added silc_string_regex_combine to combine to regex strings
4911 into one so that they can be used as one regex string by
4912 the GNU regex library. Added into the file
4913 lib/silcutil/silcutil.[ch].
4915 Added silc_string_regex_match to match two strings. It returns
4916 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4918 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4920 * Imported GNU regex to the soruce tree into lib/contrib.
4921 Fixed some compiler warning from the regex.c.
4923 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4925 * Fixed MOTD command in the server to work in router environment.
4927 * Fixed the MOTD command in the client library to support
4928 the server argument in the command.
4930 * Added `nickname_len' argument to the silc_idlist_add_client
4931 in the server, as the `nickname' argument may be binary data
4934 * Added silc_idlist_get_channels to return all channels from
4937 * Implemented LIST command to the server. Affected file is
4940 * Implemented the LIST command to the client library and on the
4943 * Added [<user count>] argument to the LIST command reply.
4944 With private channels the user count is not shown.
4946 * Updated TODO and README.
4948 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4950 * The client entry's data.registered must be TRUE even with
4951 global client entry on global client list. The data.registered
4952 is used to check whether the client is anymore in the network,
4953 for example with WHOWAS command so it must be valid.
4955 * Fixed the WHOWAS command in the server. It now actually works
4956 in router environment. Added function into silcd/command_reply.c
4957 silc_server_command_reply_whowas_save.
4959 * Added silc_idlist_purge function to the silcd/idlist.c
4960 to periodically purge the ID Cache.
4962 * Fixed INFO command in the server. It works now in router
4963 environment. Added <server name> argument to the INFO command
4964 reply. Updated the protocol specs.
4966 * Fixed minor bug in silc_idcache_purge to not purge if the
4967 expire value is zero.
4969 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4970 they were buggy because of the WHOWAS information.
4972 * Fixed local command MSG to handle the async resolving of
4973 the remote client properly. It used to fail the first MSG.
4974 Affected file silc/local_command.c.
4976 * Added `data_len' field to SilcIDCache context.
4978 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Update TODO. Todo in commands in the server.
4982 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4985 used by routers as broadcast packet to inform other routers
4986 about the changed user mode.
4988 Implemented the notify handling in the server. Affected file is
4989 silcd/packet_receive.c. Added the function
4990 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4992 * Added new generic Channel Payload and deprecated the New Channel
4993 Payload. The New Channel Payload is now the generic Channel
4996 * Added new argument `mode' to the silc_server_send_new_channel
4997 as it is required in the Channel Payload now.
4999 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5000 and created a new and real SilChannelPayload to represent the
5001 new generic Channel Payload. Implemented the encode/decode
5002 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5004 * Added silc_server_get_client_channel_list to return the list
5005 of channels the client has joined for WHOIS command reply.
5006 Affected file silcd/server.[ch].
5008 * Implemented the channel list sending in the WHOIS command reply
5009 in server and in the client.
5011 Implemented the channel list displaying on the user interface
5012 as well. Affected file silc/client_ops.c.
5014 * Added silc_channel_payload_parse_list to parse list of Channel
5015 Payloads. It returns SilcDList list of SilcChannelPayloads.
5016 Client for example can use this function to parse the list of
5017 channels it receives in the WHOIS command reply. The caller
5018 must free the list by calling silc_channel_payload_list_free.
5019 Affected files lib/silccore/silcchannel.[ch].
5021 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Added one new argument <user mode> to the WHOIS command reply
5024 to return the mode of the user in SILC. Updated the protocol
5027 Implemented it to the server and client.
5029 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Fixed the mode printing on the user interface on joining.
5032 Affected file silc/client_ops.c.
5034 * Implemented the UMODE command and user modes in general to the
5035 client library and to the user interface.
5037 * Implemented the UMODE command to the server.
5039 * The server now sends UNKNOWN_COMMAND error status if client sends
5040 unknown command. Affected file silcd/command.c.
5042 * All server commands now handle the command identifier the right
5043 way when sending the command reply to the client. The client can
5044 use to identify the command replies with the identifier.
5046 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Added silc_server_get_client_route to resolve the route to
5049 the client indicated by the client ID. Affected file is
5052 * Added silc_server_relay_packet as general function to relay
5053 packet to arbitrary destination. This deprecates functions
5054 like _send_private_message_key, _relay_notify etc. Affected
5055 file is silcd/packet_send.[ch].
5057 Removed silc_server_send_key_agreement,
5058 silc_server_send_private_message_key and
5059 silc_server_packet_relay_notify functions from the file
5060 silcd/packet_send.[ch].
5064 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5065 server. Affected file silcd/packet_receive.[ch].
5067 * Implemented the KILL command to the client. Implemented the
5068 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5069 Affected files lib/silcclient/command[_reply].c and
5070 lib/silcclient/client_notify.c. Implemented the KILL notify
5071 printing in the user inteface.
5073 * Fixed a lot silc_parse_nick memory leaks from the client
5074 library in the file lib/silcclient/command.c.
5076 * Changed the silc_server_send_notify_on_channels's `sender'
5077 argument from SilcSocketConnection to SilcClientEntry to
5078 check the sender as entry and not as connection object and not
5079 to send to the client provided as argument. The affected file
5080 is silcd/packet_send.[ch].
5082 * The notify packets that are destined directly to the client used
5083 to not to be processed by the server. Now changed that and the
5084 server processes all notify packets. After relaying the packet
5085 to the client the notify packet is processed in the server.
5087 * The silc_server_free_client_data now checks whether there is
5088 pending outgoing traffic for the client and purges the data to
5089 the network before removing the client entry.
5091 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5094 an client is killed from the SILC Network. Updated the protocol
5097 Added new function silc_server_send_notify_killed to the
5098 silcd/packet_send.[ch].
5100 * Added function silc_server_packet_relay_notify to relay notify
5101 packets that are destined directly to a client. In this case
5102 the server does not process the notify packets but merely relays
5103 it to the client. Affected file silcd/packet_send.[ch].
5105 Added also silc_server_packet_process_relay_notify to check
5106 whereto relay the notify. Affected file is
5107 silcd/packet_receive.[ch].
5109 * Implemented the KILL command to the server.
5113 * Added the backup schema desgined last fall to the protocol
5114 specs for everyone to see. The specification is in the
5115 *-spec-xx.txt draft and the packet type definitions for the
5116 backup routers is in *-pp-xx.txt draft. Thusly, added also
5117 new packet type SILC_PACKET_CELL_ROUTERS.
5119 * A big security problem in the implementation discovered. The
5120 signoff of an client did not cause new channel key generation
5121 which it of course should've done. The channel keys must be
5122 always re-generated when client leaves (or signoffs) the channel.
5123 The silc_server_remove_from_channels funtion now handles
5124 the channel key re-generation.
5126 * Added `sender' argument to the silc_server_send_notify_on_channels
5127 to not to send the client provided as argument. Affected file
5128 silcd/packet_send.[ch].
5130 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Implemented OPER and SILCOPER commands into the server and
5135 * Added silc_auth_verify and silc_auth_verify_data to verify
5136 the authentication directly from the authentication payload.
5137 It supports verifying both passphrase and public key based
5138 authentication. Affected file lib/silccore/silcauth.[ch].
5140 * Added `hash' field to the SilcIDListData structure. It is the
5141 hash negotiated in the SKE protocol. Affected file is
5144 * Slight redesigning of the SilcAuthPayload handling routines.
5145 Do not send SilcPKCS but SilcPublicKey as argument.
5147 * Implemented the public key authentication support to the
5148 serverconfig. The public key is loaded from the provided path
5149 and saved as authentication data to void * pointer. Thus,
5150 changed the unsigned char *auth_data to void *auth_data;
5152 * Fixed SHUTDOWN command to send the reply before the server
5153 is shutdown. :) Affected file silcd/command.c.
5155 * Fixed fatal bug in CONNECT command. The hostname was invalid
5156 memory and server crashed. Affected file silcd/command.c.
5158 * Fixed fatal bug in CLOSE command. The server_entry became
5159 invalid but was referenced later in the command. Affected file
5162 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Fixed fatal bug in failure packet handling. Server ignored
5165 the failure and thus crashed when it came.
5169 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5172 that the command may be executed only once in (about) 2 seconds.
5173 The old SILC_CF_LAG flag is same but allows command bursts up
5174 to five before limiting.
5176 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5177 server code. Various commands now includes the CF_LAG_STRICT
5178 flag to disallow any kind of miss-use of the command.
5180 * Fixed the silc_buffer_unformat to not to allocate any data
5181 if the length of the data is zero. It used to allocate the
5182 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5184 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5186 * Changed the format of AdminConnection configuration section
5187 in the server. Added username of the admin to the format.
5188 Affected files silcd/serverconfig.[ch].
5190 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5191 to return admin configuration data by host, username and/or
5194 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Implemented WHOWAS command to the server. Added the functions:
5198 silc_server_command_whowas_parse,
5199 silc_server_command_whowas_send_reply,
5200 silc_server_command_whowas_from_client and
5201 silc_server_command_whowas_from_server
5203 * Added <Client ID> argument to the WHOWAS command reply. Updated
5204 the protocol specs accordingly.
5206 * Implemented WHOWAS command and command_reply to the client
5209 Implemented the WHOWAS printing on the user interface.
5211 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Added new argument to the WHOWAS command reply, the real name.
5214 It is an optional argument. Updated the protocol specs.
5216 * Added SilcIDCacheDestructor callback that is registered when
5217 the SilcIDCache is allocated. The callback is called when
5218 an cache entry in the ID Cache expires, or is purged from the
5219 cache. Added into lib/silccore/idcache.[ch].
5221 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5222 to destruct the client entries when the cache entry expires.
5223 Other ID Cache's in server and in the client library ignores
5226 * If the ID Cache entry's `expire' field is zero then the entry
5227 never expires. Added boolean `expire' argument to the
5228 silc_idcache_add function in the lib/silccore/idcache.[ch].
5229 If it is TRUE the default expiry value is used.
5231 * Added silc_server_free_client_data_timeout that is registered
5232 when client disconnects. By default for 5 minutes we preserve
5233 the client entry for history - for WHOWAS command.
5235 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Added support to the server to enforce that commands are not
5238 executed more than once in 2 seconds. If server receives
5239 commands from client more frequently, timeout is registered
5240 to process the commands. Affected file silcd/command.c.
5241 Added new function silc_server_command_process_timeout.
5243 * Changed NICK_NOTIFY handling in client library to check that
5244 if the client's nickname was changed, so there is no need to
5245 resolve anything from the server.
5247 * Removed error printing from the WHOIS and IDENTIFY commands.
5248 If error occurs then it is ignored silently in the client library.
5249 The application, however, may map the received error to
5250 human readable error string. The application currently maps
5251 the NO_SUCH_NICKNAME error to string.
5253 * Made the command status message public to the application. Moved
5254 them from lib/silcclient/command_reply.c to
5255 lib/silcclient/command_reply.h. The application can map the
5256 received command status to the string with the
5257 silc_client_command_status_message function.
5259 * Added check to the server to check that client's ID is same
5260 as the Source ID in the packet the client sent. They must
5263 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Added dist-bzip hook to the Makefile.am to make bzip2
5266 compressed distributions.
5268 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Server now enforces the maximum length for the nickname and
5271 the channel as protocol specification dictates. 128 bytes for
5272 nickname and 256 bytes for channel name.
5274 * Moved the WHOIS printing to the application. The client libary
5275 does not print out the WHOIS information anymore, the application
5276 must do it. Renamed silc_client_command_reply_whois_print to
5277 the silc_client_command_reply_whois_save.
5279 The client's idle time is also sent to the application now, and
5280 the idle is shown on screen.
5282 * Added silc_client_command_reply_identify_save to save the
5283 received IDENTIFY entries.
5285 * Do not check for channel private keys in message sending and
5286 reception if the channel does not have the PRIVKEY mode set.
5287 Affected file lib/silclient/client_channel.c.
5289 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5292 just surfaced after chaning the JOIN procedure.
5294 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5296 * Added silc_client_get_clients_by_list to get client entries
5297 from Client ID list, that is returned for example by JOIN
5298 and USERS command replies. The application should use this
5299 function for example when JOIN command reply is received to
5300 resolve the clients already on the channel (library does not
5301 do that anymore as USERS command reply is not used in the JOIN
5302 procedure anymore). Affected files lib/silcclient/silcapi.h and
5303 lib/silcclient/idlist.c.
5305 * JOIN command reply and USERS command reply returns now SilcBuffer
5306 pointers instead of unsigned char pointers when returning
5307 the client list and mode list.
5309 * Added <Client ID> argument to the JOIN command reply, mainly
5310 for the server to identify for which client the command was
5311 originally sent. Updated protocol specs accordingly.
5313 * Added SilcDlist private_key pointer to the SilcChannelEntry
5314 in the client to support the channel private keys. Affected
5315 file is lib/silcclient/idlist.h.
5317 * Added SilcChannelPrivateKey argument to the function
5318 silc_client_send_channel_message so that application can choose
5319 to use specific private ke if it wants to. If it is not provided,
5320 the normal channel key is used, unless private keys are set.
5321 In this case the first (key that was added first) is used
5322 as the encryption key.
5324 * Implemented the support for channel private key handling.
5325 Implemented the following functions:
5327 silc_client_add_channel_private_key,
5328 silc_client_del_channel_private_keys,
5329 silc_client_del_channel_private_key,
5330 silc_client_list_channel_private_keys and
5331 silc_client_free_channel_private_keys
5333 Affected file lib/silcclient/client_channel.c.
5335 * Added the support for the private keys in the channel message
5336 sending and encryption and in the message reception and
5337 decryption. Affected funtions are
5338 silc_client_send_channel_message and silc_client_channel_message.
5340 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5342 * Added SKE's key verify callback to the client library's
5343 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5345 * Removed the statement that server (or router) must send USERS
5346 command reply when joining to the channel so that the client
5347 knows who are on the channel. Instead, the client list and
5348 client's mode list is now sent in the JOIN command reply to the
5349 client who joined channel. This is better solution.
5351 * Added function silc_server_get_users_on_channel and function
5352 silc_server_save_users_on_channel to the silcd/server.[ch].
5354 * Removed function silc_server_command_send_users from the
5357 * Do not show topic on the client library anymore. The topic is
5358 sent in the command reply notify to the application and the
5359 application must show the topic now.
5361 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Added client searching by nickname hash into the IDENTIFY and
5364 WHOIS commands in the server as they were clearly missing from
5365 them. Affected file is silcd/command.c.
5367 * Fixed a bug in private message receiving in the client library.
5368 The remote ID was freed and it wasn't supposed, now it is
5371 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Minor fix to the channel payload; allocate the data area, as it
5374 needs to be of specific length.
5376 * If the key agreement port is zero then the operating
5377 system will define the bound port. Affected files are
5378 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5380 * Added new function silc_channel_payload_decrypt into the file
5381 lib/silccore/silcchannel.[ch].
5383 * Moved the channel message etc, check from silc_packet_decrypt
5384 to applications. The library calls now a generic
5385 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5386 when the packet is either normal or special. This was done to
5387 allow more wide range of checking that was not allowed when
5388 the code was in library. Now applications can do virtually any
5389 checks to the packet and return to the library the decision how
5390 the packet should be processed. Affected files are
5391 lib/silccore/silcpacket.[ch].
5393 Added silc_server_packet_decrypt_check to the server and
5394 silc_client_packet_decrypt_check to the client library.
5396 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5397 to send with specified source and destination information.
5399 * Channel message delivery between routers was broken after the
5400 channel key distribution was fixed earlier. The channel key
5401 was used be to distributed to other routers as well which is not
5402 allowed by the protocol. Now this is fixed and channel keys
5403 really are cell specific and the channel message delivery between
5404 routers comply with the protocol specification.
5406 * Fixed various commands in server to check also the global list
5407 for the channel entry and not just the local list. The affected
5408 file silcd/command.c.
5410 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Added assert()s to buffer formatting and unformatting routines
5413 to assert (if --enable-debug) when error occurs. Affected
5414 file: lib/silcutil/silcbuffmt.c.
5416 * Changed to auto-reconnect to check whether the remote host is
5417 router and register the re-connect timeout if it is. It used
5418 to check that whether we are normal server, but router must do
5419 auto-reconnect with another router as well. Affected file
5422 * Removed the [<key len>] option from CMODE command as the cipher
5423 name decides the key length, nowadays. See the defined ciphers
5424 from the protocol specification.
5426 * Added [<hmac>] option to the CMODE command to define the HMAC
5427 for the channel. Added SILC_CMODE_HMAC channel mode.
5429 * Added [<hmac>] option for the JOIN command so that user can
5430 select which HMAC is used to compute the MACs of the channel
5433 * Added Hmac field to the Channel Message Payload. The integrity
5434 of plaintext channel messages are now protected by computing
5435 MAC of the message and attaching the MAC to the payload. The
5436 MAC is encrypted. Now, it is clear that this causes some
5437 overhead to the size of the packet but rationale for this is that
5438 now the receiver can verify whether the channel message decrypted
5439 correctly and also when private keys are set for the channel the
5440 receiver can decrypt the packet with several keys and check from
5441 the MAC which key decrypted the message correctly.
5443 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5444 lib/silccrypt/silccipher.[ch].
5446 * Added silc_hash_len to return the digest length into the
5447 lib/silcrypt/silchash.[ch].
5449 * Rewrote parts of Silc Channel Payload interface in the
5450 lib/silccore/silcchannel.[ch]. The encode function now also
5451 encrypts the packet and parse function decrypts it.
5453 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5455 * Fixed a minor formatting bug in the SKE's key material processing.
5456 It actually might have processed the keys wrong way resulting
5459 * Redefined the mandatory HMAC algorithms and added new algorithms.
5460 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5461 and hmac-md5 truncated to 96 bits. The mandatory is now
5462 hmac-sha1-96. Rest are optional (including the one that used
5463 to be mandatory). Rationale for this is that the truncated HMAC
5464 length is sufficient from security point of view and can actually
5465 make the attack against the HMAC harder. Also, the truncated
5466 HMAC causes less overhead to the packets. See the RFC2104 for
5469 * Added new [hmac] configuration section. The SKE used to use
5470 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5471 is of course wrong. The official names that must be proposed in
5472 the SKE are the ones defined in the protocol specification
5473 (hmac-sha1-96 for example). The user can configure any hmac
5474 using any hash function configured in the [hash] section. At
5475 least, the mandatory must be configured.
5477 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5479 * Added HMAC list to the SKE proposal list. It has now both
5480 hash algorithm list and HMAC list. This makes the protocol
5481 incompatible with previous versions. The SKE now seems to work
5482 the way it is supposed to work, for the first time actually.
5484 * Defined plain Hash algorithms to the protocol specification.
5487 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5489 * Implemented support for key agreement packets into the server.
5490 Added functions silc_server_key_agreement and
5491 silc_server_send_key_agreement. Other than these functions,
5492 server has nothing to do with this packet.
5494 * Added support for private message key packets into the server.
5495 Added functions silc_server_private_message_key and
5496 silc_server_send_private_message_key.
5500 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5501 called in the protocol's final callback instead in the END
5502 protocol state. This makes a little more sense and in the same
5503 time in client we can use the same protocol routines for normal
5504 key exchange and to key agreement packet handling as well.
5506 * Added to both client's and server's KE protocol context the
5507 SilcSKEKeyMaterial pointer to save the key material. We will
5508 bring the key material to the protocol's final callback by doing
5509 this. The final callback must free the key material.
5511 * Added SKE's packet_send callback into client's KE protocol
5512 context so that the caller can choose what packet sending function
5513 is used. This way we can use different packet sending when
5514 doing normal SKE when doing key agreement packet handling (in
5515 the key agreement packet handling we do not want to encrypt
5518 * Implemented the responder side of the key agreement routines
5519 in the client. The client can now bind to specified port and
5520 accept incoming key negotiation. The key material is passed
5521 to the application after the protocol is over.
5523 * Implemented the processing of incoming Key Agreement packet
5524 in the client. Added function silc_client_key_agreement to
5527 * Implemented the intiator side of the key agreement routines
5528 in the client. The client can now initiate key agreement with
5529 another remote client. The key material is passed to the
5530 application after the protocol is over.
5532 * Created client_keyagr.c to include all the key agreement
5535 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5536 SILC_TASK_CALLBACK except that it is not static.
5538 * Created client_notify.c and moved the Notify packet handling
5539 from the client.[ch] into that file.
5541 * Created client_prvmsg.c and moved all private message and
5542 private message key routines from the client.[ch] into that file.
5544 * Create client_channel.c and moved all channel message and
5545 channel private key routines from the client.[ch] into that file.
5547 * Changed silc_client_get_client_by_id_resolve to resolve with
5548 WHOIS command instead of IDENTIFY command, in the file
5549 lib/silclient/idlist.c.
5551 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Implemented the SKE's responder side to the Client library.
5555 * When FAILURE is received to the protocol do not trust it
5556 blindly. Register a timeout to wait whether the remote closes
5557 the connection as it should do it, only after that process the
5558 actual failure. This was changed to both client and server.
5560 * Added client_internal.h to include some of the structures
5561 there instead of client.h in lib/silcclient/.
5563 * Added function silc_task_unregister_by_callback to unregister
5564 timeouts by the callback function.
5566 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Some "Incomplete WHOIS info" errors has been appearing on the
5569 log files. Took away the entry->userinfo check from WHOIS
5570 reply sending. The entry->userinfo is now " " if client did not
5571 provide one. I thought this was fixed earlier but something
5572 is wrong still. Let's see if the error still appears.
5574 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5576 * Fixed a minor bug in the login when the channel key is
5577 re-generated in the server. It used to generate the key in
5578 wrong order and thus caused problems in the channel traffic.
5580 * Fixed a minor bug in channel key distsribution after
5581 KICK command. The key was not sent to the router even though
5584 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5586 * Added silc_ske_process_key_material_data as generic routine
5587 to process any key material as the SILC protocol dictates. The
5588 function is used by the actual SKE library but can be used by
5589 applications as well. This relates to the private message keys
5590 and the channel private keys since they must be processed the
5591 same way the normal SILC session keys. The protocol dictates
5592 this. Affected files: lib/silcske/silcske.[ch].
5594 Added also silc_ske_free_key_material to free the
5595 SilcSKEKeyMaterial structure.
5597 * Defined silc_cipher_set_key function to set the key for
5598 cipher without using the object's method function. The affected
5599 files: lib/silccrypt/silccipher.[ch].
5601 * Implemented silc silc_client_add_private_message_key,
5602 silc_client_add_private_message_key_ske,
5603 silc_client_del_private_message_key,
5604 silc_client_list_private_message_keys and
5605 silc_client_free_private_message_keys functions in the
5608 Added functions silc_client_send_private_message_key to send
5609 the Private Message Key payload and silc_client_private_message_key
5610 to handle incoming Private Message Key payload.
5612 * Added Cipher field to the Private Message Key payload to set
5613 the cipher to be used. If ignored, the default cipher defined
5614 in the SILC protocol (aes-256-cbc) is used.
5616 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Removed lib/silcclient/ops.h file.
5620 Redefined parts of the SILC Client Library API. Created new
5621 file silcapi.h that deprecates the ops.h file and defines the
5622 published Client Library API. Defined also private message key
5623 API and channel private key API into the file.
5625 This is the file that the application must include from the
5626 SILC Client Library. Other files need not be included by
5627 the application anymore.
5629 * Added new key_agreement client operation callback and also
5630 defined the Key Agreement library API for the application.
5632 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5635 is used by clients to request key negotiation between another
5636 client in the SILC network. If the negotiation is started it
5637 is performed using the SKE protocol. The result of the
5638 negotiation, the secret key material, can be used for example
5639 as private message key.
5641 Implemented the Key Agreement payload into the files
5642 lib/silccore/silauth.[ch].
5644 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Redefined ciphers for the SILC protocol. Added some new ciphers
5647 and defined the key lengths for the algorithms. Changed the
5648 code accordingly. The default key length is now 256 bits.
5650 * Fixed SKE key distribution function silc_ske_process_key_material
5651 when the key length is more than 128 bits. The default key
5652 length in SILC is now 256 bits.
5654 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5655 to indicate unsupported algorithm.
5657 * Renamed rijndael.c to aes.c and all functions as well.
5659 * Fixed a long standing channel key setting bug in client library.
5660 Weird that it has never surfaced before.
5662 * Fixed bug in channel deletion. If the entire channel is removed
5663 then it must also delete the references of the channel entry
5664 from the client's channel list as the client's channel entry and
5665 the channel's client entry share same memory.
5667 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Implemented CONNECT and SHUTDOWN commands in the client.
5671 * Implemented CLOSE command to the client.
5673 * Added the function silc_idlist_find_server_by_name into the
5674 files silcd/idlist.[ch].
5676 Added the function silc_idlist_find_server_by_conn into the
5677 files silcd/idlist.[ch].
5679 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * DIE command was renamed to SHUTDOWN. Updated the both code
5684 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5685 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5687 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5690 * Added function silc_server_create_connection function to create
5691 connection to remote router. My server implementation actually
5692 does not allow router to connect to normal server (it expects
5693 that normal server always initiates the connection to the router)
5694 so the CONNECT command is only good for connecting to another
5697 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5699 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5700 or some other client was kicked from the channel.
5702 Implemented the handling of the notify type to both client
5705 Implemented silc_server_send_notify_kicked to send the KICKED
5706 notify. It is used to send it to the server's primary router.
5708 * Implemented the KICK command into server and client.
5710 * Added `query' argument to the silc_idlist_get_client function
5711 to indicate whether to query the client from server or not if
5714 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5715 to indicate that the client is not channel founder.
5719 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * Removed the rng context from SilcPacketContext structure and
5722 changed that the packet routine uses the Global RNG API.
5724 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Added support for quit message that client can "leave" on the
5727 channel when it quits the SILC. It is ditributed inside the
5728 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5730 Added silc_server_free_client_data that will take the
5731 signoff message as argument.
5733 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5735 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Updated parts of the protocol specification to keep it up
5740 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5742 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5743 payloads in one packet.
5745 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5746 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5747 use now the new List flag.
5749 * Also deprecated the following packet types: REPLACE_ID,
5750 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5752 * Added list support for Notify packet in server.
5754 * Added silc_server_send_notify_channel_change to send the
5755 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5756 the silc_server_send_replace_id.
5758 * Added silc_server_send_notify_nick_change to send the
5759 NICK_CHANGE notify type. Deprecates the function
5760 silc_server_send_replace_id.
5762 * Added silc_server_send_notify_join to send the JOIN notify type.
5763 Deprecates the function silc_server_send_new_channel_user.
5765 * Added silc_server_send_notify_leave to send LEAVE notify type.
5766 Deprecates the function silc_server_send_remove_channel_user.
5768 * Added silc_server_send_notify_cmode and
5769 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5770 types. Deprecates the silc_server_send_set_mode function.
5772 * Added SERVER_SIGNOFF notify type to indicate that server has
5773 quit. This means that all clients on the channel from that
5774 server will drop. This can be also used when netsplit happens.
5776 Deprecated REMOVE_ID packet type since it is not needed anymore
5779 Added silc_server_send_notify_server_signoff to send the
5780 SERVER_SIGNOFF notify type. Deprecates the function
5781 silc_server_send_remove_id.
5783 Added also silc_server_send_notify_signoff to send the
5784 SIGNOFF notify type.
5786 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5787 SILC protocol from this day on. Changed the protocol
5788 specification as well.
5790 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5791 notify type. It is used between routers to notify about
5792 topic changes on a channel.
5794 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5797 * Partly updated the protocol specification to comply with the
5798 changes now made. It is still though a bit outdated.
5800 * The JOIN notify type now takes one extra argument <Channel ID>.
5801 The packet used to be destined to the channel but now the
5802 JOIN type may be sent as list thus it is impossible to
5803 destine it to any specific channel. By adding this argument
5804 it is again possible.
5806 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Added CREDITS file. The CHANGES and CREDITS file will appear
5809 in the distribution as well.
5811 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5814 types in the server's silcd/packet_receive.c.
5816 * Implemented CMODE and CUMODE to work in router environment.
5818 * Fixed minor encoding and decoding buglet from the
5819 lib/silccore/silcmode.c.
5821 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5824 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5826 * Changed all SilcConfigServer* and silc_config_server* to
5827 SilcServerConfig* and silc_server_config*, respectively.
5830 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Associated the ID (client or server ID) to the Authentication
5833 Payload to avoid any possibility of forging. Updated the
5834 protocol specification and the code accordingly.
5836 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5838 * The RSA key length is now save to the RsaKey context in the
5839 key generation process in lib/silccrypt/rsa.c. The key length
5840 is now used to figure out the maximum size of the block allowed
5841 to be encrypted/signed.
5843 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5844 is equivalent to the silc_mp_mp2bin but does not allocate any
5847 * Changed silc_mp_mp2bin API to take length argument. If it is
5848 non-zero then the buffer is allocated that large. If zero, then
5849 the size is approximated using silc_mp_sizeinbase, which however
5852 * Created Global RNG API which is global RNG that application can
5853 initialize. After initializing, any routine anywhere in the
5854 code (including library) can use RNG without allocating a new
5855 RNG object. This was done to allow this sort of use of the
5856 RNG in code that has no chance to allocate RNG object. All
5857 applications currently allocate this and many routines in the
5858 library use this. Affected file lib/silccrypt/silcrng.[ch].
5860 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5861 it to use the Global RNG API.
5863 * Defined Authentication Payload into protocol specification that
5864 is used during SILC session to authenticate entities. It is
5865 used for example by client to authenticate itself to the server
5866 to obtain server operator privileges.
5868 Implemented this payload into the lib/silccore/silcauth.[ch].
5869 Implemented also routines for public key based authentication
5870 as the new protocol specification dictates.
5872 Moved definitions of different authentication methods from
5873 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5875 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5876 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5877 silc_pkcs_verify_with_hash functions into the file
5878 lib/silccrypt/silcpkcs.[ch].
5880 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5882 * The client entry's userinfo pointer must be always valid.
5883 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5884 will fail since it requires the userinfo. Now, the userinfo
5885 is allocated as "" if actual userinfo does not exist. Actually,
5886 it must exist and it is totally Ok to drop client connections
5887 that does not announce the userinfo. However, we will make
5888 this workaround for now.
5890 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5891 to return the remote port by socket.
5893 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5896 SILC_SERVER_PENDING_EXEC and added an new macro
5897 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5898 data or when error occurs while processing the pending command.
5900 Added new argument `destructor' into silc_server_command_pending
5901 and to the SilcServerCommandPending object. This destructor is
5902 now called after calling the pending callback or if error occurs
5903 immediately. If error occurs the actual pending callback won't
5904 be called at all - only the destructor. The destructor may be
5905 NULL if destructor is not needed.
5907 All this applies for client library code as well. Similar
5908 changes were made there as well for the pending commands.
5910 In the client, the application must now allocate the
5911 SilcClientCommandContext with the silc_client_command_alloc
5914 * Added reference counter to the SilcServerCommandContext. Added
5915 function silc_server_command_alloc and silc_server_command_dup
5918 Same type of functions added to the client library for the same
5921 * Removed the cmd_ident from IDListData away since it is now
5922 global for all connections. It is the command identifier used
5923 in command sending and with pending commands. The affected file
5926 * Added reference counter to the SilcSocketConnection objecet to
5927 indicate the usage count of the object. The object won't be
5928 freed untill the reference counter hits zero. Currently only
5929 server uses this, and client ignores it. The client must be
5930 set to use this too later. The affected files are
5931 lib/silccore/silcsockconn.[ch]. Added also the function
5932 silc_socket_dup to increase the reference counter.
5934 This was mainly added because it is possible that the socket
5935 is removed underneath of pending command or other async
5936 operation. Now it won't be free'd and proper DISCONNECTING
5937 flags, etc. can be set to avoid sending data to connection that
5938 is not valid anymore.
5940 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5941 the connection. After that it sets SILC_SET_DISCONNECTED.
5942 It is, however, possible that the socket data is not still freed.
5943 The silc_server_packet_process now checks that data is not
5944 read or written to connection that is DISCONNECTED. The socket
5945 get's freed when the reference counter hits zero.
5947 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Changed the client operation API: channel_message operation's
5950 `sender' is now the client entry of the sender, not the nickname
5951 and the `channel' is the channel entry, not the channel name.
5953 In the private_message operation the `sender' is now also the
5954 client entry of the sender not the nickname.
5956 Affected file is lib/silcclient/ops.h and all applications
5957 using the client operations.
5959 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Moved the calling of ops->connect() from connect_to_server_final
5962 into receive_new_id functin since that is the point when the
5963 client is actually allowed to send traffic to network. The
5964 affected file is lib/silcclient/client.c.
5966 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5969 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5970 (if needs broadcasting) instead of broadcasting the packets one
5971 by one which would make a burst in the network traffic.
5973 * Added `broadcast' argument to the functions in silcd/server.[ch]
5974 silc_server_create_new_channel[_with_id] to indicate whether
5975 to send New Channel packet to primary router.
5977 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * Added new function into the silcd/server.[ch] files:
5980 silc_server_create_new_channel_with_id to create new channel with
5981 already existing Channel ID.
5983 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5984 lib/silccore/silcpacket.h. This packet is used t send list of
5985 Set Mode payloads inside one packet. Server uses this to set
5986 the modes for the channels and clients on those channels, that it
5987 announced to the router when it connected to it. The protocol
5988 specification has been updated accordingly.
5990 * The silc_server_new_channel did not handle the packet coming
5991 from normal server as it normally does not send that. However,
5992 when it announces its channels it does send it. Implemented
5993 the support for that.
5995 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5996 into the file lib/silccore/id.h.
5998 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6000 * Fixed memory leaks in the functions silc_idlist_del_client,
6001 silc_idlist_del_channel and silc_idlist_del_server in the file
6002 silcd/idlist.c. All of those leaked like a sieve.
6004 * Fixed some small memory leaks in the client's function
6005 silc_client_notify_by_server.
6007 * Added functions into silcd/server.c: silc_server_announce_clients,
6008 silc_server_announce_channels and silc_server_announce_server.
6009 These functions are used by normal and router server to announce
6010 to its primary router about clients, channels and servers (when
6011 router) that we own. This is done after we've connected to the
6014 These functions effectively implements the following packet types:
6015 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6016 and SILC_PACKET_NEW_ID_LIST.
6018 * Added new functions into the silcd/packet_receive.[ch]:
6019 silc_server_new_id_list, silc_server_new_channel_list and
6020 silc_server_new_channel_user_list to handle the incoming
6021 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6023 * Added support of changing Channel ID in the function
6024 silc_server_replace_id. If the server that announces a channel
6025 to the router already exists in the router (with same name but
6026 with different Channel ID), router is responsible to send
6027 Replace ID packet to the server and force the server to change
6028 the Channel ID to the one router has.
6030 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6031 client that the Channel ID has been changed by the router. The
6032 normal server sends this to the client. Client must start using
6033 the new Channel ID as the channel's ID.
6035 Implemented handling of this new type into lib/silcclient/client.c
6036 into the function silc_client_notify_by_server.
6038 * Added new function silc_idlist_replace_channel_id into the files
6039 silcd/idlist.[ch] to replace the Channel ID.
6041 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6043 * Call silc_server_command_identify_check always when processing
6044 the IDENTIFY command in silcd/command.c
6046 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6048 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6049 send keepalive packets. The packet can be sent by clients,
6050 servers and routers.
6052 Added function silc_socket_set_heartbeat into the file
6053 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6054 If not set, the heartbeat is not performed. The actual
6055 heartbeat is implemented in the low level socket connection
6056 library. However, application is responsible of actually
6059 Added silc_server_send_heartbeat to send the actual heartbeat
6060 packet into silcd/packet_send.[ch]. Server now performs
6061 keepalive with all connections.
6063 * Added silc_task_get_first function into lib/silcutil/silctask.c
6064 to return the timeout task with shortest timeout. There was a bug
6065 in task unregistration that caused problems. TODO has been
6066 updated to include that task system must be rewritten.
6068 * The client library will now resolve the client information when
6069 receiving JOIN notify from server for client that we know but
6070 have incomplete information.
6072 * Rewrote parts of silc_server_remove_from_channels and
6073 silc_server_remove_from_one_channel as they did not remove the
6074 channel in some circumstances even though they should've.
6076 * Encryption problem encountered in server:
6078 The LEAVE command used to send the Channel Key packet to the
6079 router immediately after generating it. However, the code
6080 had earlier sent Remove Channel user packet but not immediately,
6081 ie. it was put to queue. The order of packets in the router
6082 was that Channel Key packet was first and Remove Channel User
6083 packet was second, even though they were encrypted in the
6084 reverse order. For this reason, MAC check failed. Now, this
6085 is fixed by not sending the Channel Key packet immediately but
6086 putting it to queue. However, this is more fundamental problem:
6087 packets that are in queue should actually not be encrypted
6088 because packets that are sent immediately gets encrypted
6089 actually with wrong IV (and thus MAC check fails). So, packets
6090 that are in queue should be encrypted when they are sent to
6091 the wire and not when they put to the queue.
6093 However, the problem is that the current system has not been
6094 designed to work that way. Instead, the packet is encrypted
6095 as soon as possible and left to the queue. The queue is then
6096 just purged into wire. There won't be any fixes for this
6097 any time soon. So, the current semantic for packet sending
6100 o If you send packet to remote host and do not force the send
6101 (the packet will be in queue) then all subsequent packets to the
6102 same remote host must also be put to the queue. Only after the
6103 queue has been purged is it safe again to force the packet
6106 o If you send all packets immediately then it safe to send
6107 any of subsequent packets through the queue, however, after
6108 the first packet is put to queue then any subsequent packets
6109 must also be put to the queue.
6111 Follow these rules and everything works fine.
6113 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6115 * Added new function silc_server_remove_clients_by_server to
6116 remove all client entries from ID list when the server connection
6117 is lost. In this case it is also important to invalidate all
6118 client entires as they hold the invalid server entry. This
6119 fixes fatal bug when server has lost connection and will reconnect
6122 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Made some sanity checks to silc_server_daemonise like to check
6125 whether the requested user and group actually exists.
6127 * Added sanity check to SKE's silc_ske_responder_finish to check
6128 that the public and private key actually is valid.
6130 * Invalidate the client's nickname when receiving Replace ID
6131 packet and the Client ID is being replaced. This means that the
6132 server will query the nickname if someone needs it (client)
6135 * Sort the ID Cache in client library when the ID Cache data
6136 has changed (needs sorting).
6138 * Do not allow for SILC client to create several connections to
6139 several servers. The client does not support windows right now
6140 and generating multiple connections causes weird behaviour.
6142 Irssi-silc client does support windows and can handle several
6143 connections without problems, see: www.irssi.org and SILC plugin.
6145 * Fixed some places where client was added to the IDList. The
6146 rule of thumb is following (in order to get everything right):
6147 If the client is directly connected local client then the
6148 `connection' argument must be set and `router' argument must be
6149 NULL to silc_idlist_add_client function. If the client is not
6150 directly connected client then the `router' argument must
6151 bet set and the `connection' argument must be NULL to the
6152 silc_idlist_add_client function.
6154 * The funtion silc_server_packet_send_local_channel actually did
6155 not check whether the client was locally connected or not. It
6156 does that now. Fixed a bug related to LEAVE command.
6158 * Fixed Remove Channel User payload parsing bug in server's
6159 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6161 * The server's silc_server_save_channel_key now checks also the
6162 global ID list for the channel as it might not be in the local
6163 list. Fixed a bug related to LEAVE command.
6165 * Is this the end of the [<unknown>] buglet that has been lurking
6166 around for a long time? A little for loop fix in server's
6167 silc_server_command_whois_parse that is used by both IDENTIFY
6168 and WHOIS command. At least, this was a clear bug and a cause
6169 of one type of [<unknown>] buglet.
6171 * WHOIS and IDENTIFY commands call the function
6172 silc_server_command_[whois/identify]_check function even if
6173 we are not router server.
6175 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6177 * Added --with-gmp configuration option. If set the GMP
6178 is always compiled in the SILC source tree. If not set then
6179 it is checked whether the system has the GMP3 installed. If
6180 it has then the GMP won't be compiled (the system's headers
6181 and library is used), if it doesn't have it then the GMP is
6182 compiled in the SILC source tree.
6184 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6186 * Changed RSA private exponent generation to what PKCS #1
6187 suggests. We try to find the smallest possible d by doing
6188 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6189 not security fix but optimization.
6191 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6193 * Added new config entry [Identity] to fork the server and run
6194 it as specific user and group. A patch from Bostik.
6196 * Imported Dotconf configuration library into lib/dotconf.
6197 This will be used to create the SILC configuration files later.
6198 It will appear in the distsribution after this commit.
6200 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6202 * A big code auditing weekend happening. Auditing code for
6203 obvious mistakes, bugs and errors. Also, removing any code
6206 Removed files for being obsolete:
6208 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6209 inline in the file lib/silcutil/silcbuffer.h)
6211 o lib/silcutil/silcbufutil.c (the header has inline versions)
6213 Changed code to fix possible error conditions:
6215 o The buffer formatting routines now check that the destination
6216 buffer really has enough space to add the data. This applies for
6217 both buffer formatting and unformatting
6218 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6219 unformatting was changed to accomodate following rules:
6220 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6221 sent to the function while XXX_*STRING will not allocate or copy
6222 the data into the buffer. Instead it sets the pointer from the
6223 buffer into the pointer sent as argument (XXX_*STRING used to
6224 require that the pointer must be allocated already). This change
6225 makes this whole thing a bit more consistent and more optimized
6226 (note that the data returned in the unformatting with XXX_*STRING
6227 must not be freed now). The routines return now -1 on error.
6229 o Tried to find all code that use buffer_format and buffer_unformat
6230 and added return value checking to prevent formatting and
6231 especially unformatting errors and possible subsequent fatal
6234 o Changed ske->x and ske->KEY to mallocated pointers in
6235 lib/silcske/silcske.h. Fixed possible data and memory leak.
6237 o Added return value checking to all *_parse* functions. Fixed
6238 many memory leaks as well.
6240 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6241 so that buffer overflows would not happen. All code now also
6242 checks the return value as it can fail.
6244 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Added reconnection support to server if the normal server looses
6247 its connection to the router (for example if router is rebooted).
6248 The server performs normal reconnection strategy implemented
6249 to the server. Affected file silcd/server.c.
6251 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6253 * Added new packet type SILC_PACKET_SET_MODE that is used to
6254 distribute the information about changed modes (for clients,
6255 channels and clients channel modes) to all routers in the
6256 network. Updated the protocol specification accordingly.
6258 Added functions into silcd/packet_send.c and
6259 silcd/packet_receive.c: silc_server_send_set_mode,
6260 silc_server_set_mode.
6262 Added new files silcmode.[ch] into lib/silccore that implements
6263 the encoding and decoding of Set Mode Payload. Added new type
6264 SilcSetModePayload. Moved the definitions of different modes
6265 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6267 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6269 * Oops, a little mistake in server's connection authentication
6270 protocol. The protocol is not ended with FAILURE but with
6271 SUCCESS if the authentication is Ok. :) Affected file is
6274 * Implemented NICK_CHANGE notify handling in server in the file
6275 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6276 the local clients on the channel. After the changing nickname
6277 in router environment snhould work and the [<unknown>] nickname
6278 should appear no more.
6280 The silc_server_replace_id function that receives the Replace ID
6281 payload now sends the NICK_CHANGE notify type also in the file
6282 silcd/packet_receive.c
6284 * Changed WHOIS and IDENTIFY command to support the maximum amount
6285 of arguments defined in protocol specs (3328 arguments). This
6286 fixed a bug that caused problems when there were more than three
6289 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6291 * Added extra parameter, command identifier, to the
6292 silc_client_send_command so that explicit command identifier
6295 Changed that ID list routines uses specific command identifier
6296 when sending WHOIS/IDENTIFY requests to the server so that they
6297 can be identified when the reply comes back.
6299 Affected files lib/silcclient/command.[ch],
6300 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6302 * Added `sender' argument to silc_server_packet_send_to_channel
6303 to indicaet the sender who originally sent the packet to us
6304 that we are now re-sending. Ignored if NULL. Affected file
6305 silcd/packet_send.[ch].
6307 * Added some server statistics support in silcd/server_internal.h
6308 SilcServerStatistics structure and around the server code. Also
6309 send some nice statistics information when client is connecting
6312 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Fixed channel ID decoding in server's JOIN command reply in
6315 silcd/command_reply.c
6317 * Fixed braodcasting of replace ID payload to not to send it if
6318 we are standalone server in silcd/packet_receive.c.
6320 * Fixed all channel message sending routines to not to send
6321 packets to clients that has router set, since they are routed
6322 separately in the same function earlier. Affects file
6323 silcd/packet_send.c and all channel packet sending functions.
6325 * In USERS reply, res_argv[i] are not allocated, the table
6326 is allocated. Thus changed that free the table, not its
6329 * In server's whois_check and identify_check if the client is
6330 locally connected do not send any WHOIS commands - they are not
6333 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Fixed some minor bugs in client when sending WHOIS command. The
6336 arguments was in wrong order.
6338 * Removed statis function add_to_channel from server in
6339 silcd/command.c that was previously used with the joining but
6342 * Tested USERS command in router environment successfully with two
6343 routers, two servers and two clients.
6345 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Reorganized the USERS command and command reply in client library
6348 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6349 When the command is given by user we register a pending command
6350 callback that will reprocess the command after the reply has been
6351 received from the server. When reprocessing the packet we then
6352 display the information. Thus, the USERS information is displayed
6353 now in the command callback instead of in the command reply
6354 callback. The processing of the command is same as previously
6355 when server has sent the command reply in the JOINing process.
6357 * Added to USERS command in silcd/command_reply.c to join the client,
6358 we didn't use to know about, to the channel after we've created
6359 a client entry for it. Also, for clienet we did know already still
6360 check whether it is on the channel or not and add it if not.
6362 * Removed silc_server_command_join_notify as the function and its
6365 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Changed the client's pending command handling to the same as the
6368 server's pending command handling. It is also now possible to
6369 execute command reply functions from other command reply
6370 function as the function callbacks for commands and command
6371 replies are one and same. The pending commands are not static
6372 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6373 in client connection context. Thus, pending commands are server
6374 connection specific as it is convenient.
6376 Changed the function silc_client_command_pending and
6377 silc_client_command_pending_del and added new function
6378 silc_client_command_pending_check. Removed the
6379 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6382 * Added cmd_ident, current command identifier, to the client
6383 connection context in lib/silcclient/client.h to keep track on
6384 command identifiers used in command sending. Client's command reply
6385 function handling now supports the mandatory command identifiers.
6387 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6388 funtions in client to fully support pending command callbacks.
6390 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6391 as one of the arguments to the application in the command reply
6394 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6395 before first releasing SILC but came back. Now it is removed again
6396 and should come back nomore. The FORWARDED flag was used only
6397 by the JOINing procedure by forwarding the command packet to router.
6398 Now, the JOINing procedure has been changed to more generic (due
6399 to various router environment issues) and FORWARDED is not needed
6400 anymore for anything. The protocol specification is yet to be
6403 Now, removed silc_server_packet_forward from server and the flag
6404 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6406 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6408 * Renamed NAMES command to USERS command. The NAMES was named that
6409 due to historical reasons. Now it is renamed. Also, rewrote
6410 parts of the USERS command. The nickname list is not sent anymore
6411 by the server. Only Client ID and mode lists are sent in the USERS
6412 command. Changed this also to the protocol specification.
6414 The client now resolves the names and stuff after it receives
6415 the USERS list from the server when joining to the channel.
6417 * WHOIS and IDENTIFY commands has been changed to support multiple
6418 Client ID's per command. One can now search for multiple users
6419 in the network by sending only one WHOIS or IDENTIFY command.
6420 Changed the code and the protocol specifications.
6422 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6423 uses silc_server_command_whois_parse to parse the request. */
6425 * If normal server, do not parse the WHOIS and IDENTIFY requests
6426 before sending it to the router. Saves some time.
6428 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6430 * Fixed JOIN command on client library. Wrong number of arguments
6431 used to crash the client.
6433 * Added silc_server_channel_has_global function to check whether
6434 channel has global users or not.
6436 * Added silc_server_channel_has_local function to check whether channel
6437 has locally connected clients on the channel.
6439 * The silc_server_remove_from_one_channel now checks whether the
6440 channel has global users or not after given client was removed from
6441 the channel. It also checks whether the channel has local clients
6442 on the channel anymore. If it does not have then the channel entry
6443 is removed as it is not needed anymore.
6445 * The silc_server_notify now checks on JOIN notify whether the joining
6446 client is one of locally connected or global. If it is global then
6447 the channel has now global users on the channel and that is marked
6448 to the channel entry. Also, it now saves the global client to
6449 global list who is joining and JOINs it to the channel. This is
6450 for normal server, that is.
6452 Changed silc_server_send_notify_on_channel,
6453 silc_server_packet_relay_to_channel and
6454 silc_server_packet_send_to_channel check if we are normal server
6455 and client has router set (ie. global client) do not send the
6456 message to that client, as it is already routed to our router.
6458 * Implemented LEAVE notify type handling in silc_server_notify
6461 * Tested LEAVE command in router environment successfully. Tested
6462 with two routers, two servers and two clients.
6466 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6468 * Implemented SIGNOFF notify type handling in silc_server_notify
6471 * silc_server_remove_id now removes the client entry from all channels
6472 it has joined and thusly sends SIGNOFF notify type.
6474 * Rewrote the NAMES list generation in server by removing two excess
6475 loops. The lists are created now inside one loop.
6477 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6479 * silc_server_remove_channel_user checks now also global list
6480 for channel and client.
6482 * silc_server_new_channel_user checks now both local and global
6483 list for channel and client. Fixed a bug in client id decoding.
6484 Used to decode wrong buffer.
6486 * silc_server_channel_message checks now both local and global
6487 list for channel entry.
6489 * Tested channel joining (hence JOIN) in router environment
6490 successfully. Tested with two routers, two servers and two
6493 * Tested channel message sending in router environment successfully.
6495 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Added silc_server_save_channel_key into server.[ch] to save the
6498 received channel key in Channel Key payload processing. It is
6499 also used in JOIN command reply handling.
6501 Equivalent function silc_client_save_channel_key added into
6502 client.[ch] into client library.
6504 * Changed JOIN command reply to send information whether the channel
6505 was created or not (is existing already) and the channel key
6506 payload. Changed protocol specs accordingly.
6508 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6509 the request was sent by ID and not by nickname. Crashed on
6512 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6515 now correctly save the received data.
6517 * silc_server_free_sock_user_data now notifies routers in the
6518 network about entities leaving the network.
6520 At the same time implemented functions silc_server_remove_id
6521 and silc_server_send_remove_id to receive and send REMOVE_ID
6522 packets. The packet is used to notify routers in the network
6523 about leaving entities. The ID removed will become invalid in
6526 * Added function silc_idlist_del_server into server. Removes and
6527 free's server entry from ID list.
6529 * silc_server_private_message function now checks, if we are router,
6530 that the destination ID really is valid ID, naturally.
6532 * In router when NEW_ID packet is received (for new client) the
6533 hash of the Client ID is saved in the ID Cache but the
6534 client->nickname is set to NULL, instead of putting the hash
6537 IDENTIFY command now also checks that client->nickname must be
6538 valid. If it is not if will request the data from the server who
6539 owns the client. Added new function
6540 silc_server_command_identify_check.
6542 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6543 to set the command to already allocated Command Payload.
6545 * Tested private message sending in router environment with two
6546 routers, two servers and two clients. Fixed minor bugs and now
6549 * Fixed segfault from client's NAMES command. Used to crash if
6552 * Forwarded packets must not be routed even if it is not destined
6553 to the receiver. Changed server code comply with this.
6555 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6557 * Added `require_reverse_mapping' boolean value to ServerParams
6558 structure. If TRUE (not default) the server will require that
6559 the connecting host has fully qualified domain name.
6561 If the reverse mapping is not required and hostname could not be
6562 found the IP address is used as hostname.
6564 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6566 * Implemented version string checking to both client and server.
6567 The check is incomplete currently due to the abnormal version
6568 strings used in development version of SILC.
6570 * Changed all command functions in server to use the new
6573 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6575 * Changed char *data to unsigned char *data in ID Cache system to
6576 support binary data as ID Cache data. Changed code to support
6577 binary data in lib/silccore/idcache.c.
6579 * Renamed silc_server_packet_relay_command_reply to
6580 silc_server_command_reply as it is normal packet receiving
6581 function. Rewrote the function to accept command replys for
6582 servers and not only for clients.
6584 * Mark remote router always as registered server if we are connecting
6585 to it. Otherwise, commands sent by the router to us are ignored.
6587 * All ID List find routines now returns the ID Cache Entry pointer
6588 as well if requested.
6590 * WHOIS command works now in router environment, tested with two
6591 routers, two servers and two clients.
6593 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6594 in router environment (as it is almost equivalent to WHOIS) but
6595 hasn't been tested thoroughly. Added new functions:
6597 silc_server_command_identify_parse
6598 silc_server_command_identify_send_reply
6599 silc_server_command_identify_from_client
6600 silc_server_command_identify_from_server
6602 * Disabled route cache adding because adding two different ID's with
6603 same IP replaces the old cache entry thus giving wrong route.
6604 The entry->router->connection is always the fastest route anyway
6605 so route cache may not be needed. Of course, new routes maybe
6606 established after receiving the ID when the entry->router->connection
6607 might not be anymore the most optimal.
6609 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6611 * Add route cache for received ID for fast routing.
6613 * Added silc_server_packet_route to route received packet on router
6614 that is not destined to us.
6616 * Renamed silc_server_get_route to silc_server_route_get.
6618 * Added id_string and id_string_len fields into SilcServer to
6619 include encoded ServerID for fast comparing without excess
6620 encoding of the ID's.
6622 * Cleaned up WHOIS command on server side. Added following static
6625 silc_server_command_whois_parse
6626 silc_server_command_whois_check
6627 silc_server_command_whois_send_reply
6628 silc_server_command_whois_from_client
6629 silc_server_command_whois_from_server
6631 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6632 arguments in command replies. All command functions should be
6633 updated to use this macro.
6635 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6637 * Minor typo fixes on command reply handling on server.
6639 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6641 * Added silc_server_command_add_to_channel internal routine to add
6642 the client to the channel after router has created the channel and
6643 sent command reply to the server.
6645 * Added generic silc_server_send_command to send any command from
6648 * Use static buffer with ID rendering instead of duplicating data.
6650 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6652 * Fixed a channel user mode bug when joining to a channel server gave
6653 everybody channel founder rights, oops.
6655 * We mark ourselves as the router of the incoming server connection
6656 if we are router ourselves. This way we can check in some packet
6657 sending functions whether it is locally connected server. For
6658 incoming router connections we put NULL.
6660 * For router sending packets locally means now always sending the
6661 packet cell wide; to local clients and local servers. For normal
6662 server sending packet locally means sending it to only local
6665 * Fixed the JOIN command to really work in router environment. If the
6666 channel is created it is always created by the router. Router is
6667 also responsible of making the initial joining to the channel,
6668 sending JOIN notify to the sending server and distributing
6669 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6670 does not exist server doesn't do anything else but forward the
6671 command to the router which performs everything.
6673 * Added silc_server_send_channel_key function to send the Channel Key
6676 * Added silc_server_create_channel_key to create new channel key. The
6677 channel key is now re-generated everytime someone joins or leaves
6678 a channel, as protocol dictates. Note: channel->key_len is the
6681 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6683 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6684 packet_receive.[ch] to separate packet sending and receiving
6685 routines. The server.[ch] now includes everything else including
6686 actual packet processing (writing and reading data) and other
6689 Renamed silc_server_private_message_send_internal to
6690 silc_server_send_private_message. The routine is still though
6691 used only to relay private messages as server does not send
6692 private messages itself.
6694 Renamed silc_server_new_channel to silc_server_create_new_channel
6695 and added new function sicl_server_new_channel that handles the
6696 incoming New Channel packet. Added also new sending function
6697 silc_server_send_new_channel to send New Channel Payload.
6699 * Added new function silc_server_notify to process incoming notify
6700 packet to the server/router. Server may then relay the notify
6701 to clients if needed.
6703 * Added new function silc_server_new_channel_user to process incoming
6704 New Channel User packet. Router will redistribute the packet and
6705 send JOIN notify to its local clients and locally connected servers
6706 if needed. Normal server will send JOIN notify to its local client
6707 on same channel when received this packet. Added also corresponding
6708 sending function silc_server_send_new_channel_user to sent the
6711 * Added boolean route argument to send_notif_to_channel and
6712 packet_send_to_channel functions to attempt to route the packet
6713 if it is TRUE and send only locally if it is FALSE.
6715 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6717 * silc_server_replace_id now broadcasts the received replace ID
6718 packet if it is not broadcast packet already. The router must
6719 broadcast to inform other routers about changed ID.
6721 * Added backpointer to server's router into SilcServer context in
6722 silcd/server_internal.h.
6724 * Fixed silc_server_packet_broadcast to send correct broadcast
6727 * The channel key is now distributed to the local client as soon
6728 as it is received from the router (in router environment) so that
6729 no other packet may be sent for the channel until client has
6732 * silc_server_remove_channel_user now broadcasts the received
6733 Remove Channel User packet if it is not broadcast packet already.
6734 The router must broadcast to inform other routers about removed
6737 * Added users field into SilcPacketContext that is a reference count
6738 of the context. One can increase the reference count by calling
6739 silc_packet_context_dup which is now changed to just increase the
6740 reference count instead of duplicating the data. The reference
6741 count is decresed by calling silc_packet_context_free that will
6742 free the data after the reference count hits zero.
6744 For now on the packet context and everything allocated into it
6745 (including the raw packet from network) must be freed by calling
6746 the new silc_packet_context_free function. Added also new function
6747 silc_packet_context_alloc that must be used now to allocate the
6748 context. This also means that if a routine is asynchronous from
6749 silc_[client/server]_packet_parse_type the packet context must
6750 be duplicated by calling silc_packet_context_dup. Otherwise it
6751 gets free'd after silc_[client/server]_packet_parse_type returns.
6752 Also, one must remember that if packet is duplicated then its
6753 reference count must be decresed by calling the free function as
6754 many times as it was duplicated.
6756 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6757 from both client and server.
6759 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6761 * Made joining to a channel working in router environment.
6763 * Cleaned up JOIN command on server side and create function
6764 silc_server_command_join_channel internal routine to make the
6767 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * Changed silc_command_pending list to SilcDList. Also, added
6770 `ident' field to SilcServerCommandPending structure to identify
6771 the reply and to call correct callback.
6773 Added silc_server_command_pending_check function to replace the
6774 corresnponding macro. The silc_command_pending list is not
6777 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6778 to set identifier to previously allocated Command Payload. It
6779 is used to set identifier for command when resending Command
6782 * Added silc_command_payload_encode_payload to encode Command
6783 Payload buffer from SilcCommandPayload structure.
6785 * Added silc_argument_payload_encode_payload to encode Argument
6786 payload buffer from SilcArgumentPayload structure.
6788 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6790 * Changed WHOIS command to support router connection on server side.
6791 The whois request is always sent to router unless the server is
6792 standalone server. After server has received the reply from the
6793 router will it send the reply to the client.
6795 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6796 broadcast received broadcast packet. The function is used only
6797 by router. The broadcast packet is always sent to the router's
6800 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6801 render given ID to printable string, for log files for example.
6803 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6805 * Made basic router to router connections working. At least they
6806 can now connect to each other but nothing really works the way
6807 they are supposed - yet.
6809 * Added new initiator token to RouterConnection configuration
6810 file in silcd/serverconfig.[ch]. It is used to tell whether we
6811 are the initiator to the remote router or whether we'll expect
6812 the other end to connect.
6814 * Moved registering of listener task to silc_server_init, hence
6815 the server starts listenning as soon as it is run, even if it
6816 does not have connections to other routers. Let's see how well
6819 * Changed default connection retry timeouts for more suitable in
6822 * Removed cipher and such arguments from silc_idlist_add_client
6823 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6824 Added new function silc_idlist_add_data to add the keys and stuff
6827 * Added SilcIDListData structure and added it to SilcClientEntry
6828 and SilcServerEntry as their first field in the structure. This
6829 way we can explicitly cast the ID entries to the SilcIDListData
6830 structure and get common data for the entries. In past, we had
6831 to first check what type of connection it is and then cast it to
6832 correct ID entry type. Now, we can directly cast the opaque
6833 pointer to the SilcIDListData (no matter what ID entry it actually
6834 is) and get the data needed.
6836 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6838 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6839 in some circumstances even if threre were timeout tasks, though not
6840 IO tasks, but tasks anyway. Now fixed.
6842 * Defined SilcServerConnection structure to hold connection specific
6843 stuff about directly connected servers and routers. The definition
6844 is currently in silcd/server_internal.h. I thought about having
6845 a bit more important role fro this struct but for now it is used
6846 only when connecting to other server (or router actually).
6848 * Added connecting retry support in server when connecting to
6849 router(s). The retry feature implement exponential backoff
6850 algorithm. Also, added SilcServerParams structure to hold default
6851 parameters for server. For now, it include these retry settings
6852 and are hard coded. After server is moded to be as Silc Server
6853 Library this structure will be more important.
6855 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6857 * Changed client librarys channel->clients table to SilcList and
6858 changed code accordingly.
6860 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * Changed client's channel table to SilcList and changed code
6863 accordingly. Also changed SilcChannelClientEntry to include back-
6864 pointer to the channel so that client entry can use that structure
6865 as list as well and we have fast cross-reference to the channel.
6866 This change dramatically decreased the complexity of channel
6867 handling with client entry and vice versa (removed one extra
6868 loop when searching for channel entry from many functions).
6870 * Changed server->sim from table to SilcDList and changed code
6873 * NAMES command can now be used from user interface. It will show
6874 the user list on the channel, neatly.
6876 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6877 Code now saves realname of the user if it becomes available.
6879 * Renamed configure.in to configure.in.pre and made ./prepare
6880 script to automatically add correct version string to
6881 configure.in which it creates from configure.in.pre.
6883 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6885 * NAMES command reply now shows users mode with the nickname when
6888 * Moved silc_client_ch[u]mode[_char] functions from
6889 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6890 place sucks, they are utility functions and should be in some
6893 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6895 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6898 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Added TRQ (efficient deque and list library) into lib/trq. This is
6903 a very good list library that is currently used in the SILC. Defined
6904 SilcList API over the library because I didn't like the API very
6905 much. See lib/trq/silclist.h for the API and examples of how to
6906 use the API. Fixed various places in the code to use the new
6907 SilcList API. The SilcList is meant for lists that has a structure
6908 already defined as a list. It is not suitable to add just some
6909 context to the list (in TRQ, the context is the list actually).
6911 So, I defined SilcDList that can be used for the purpose where
6912 predefined list structure does not exit. This can be used as
6913 such list. Now some context just can be added to the SilcDList.
6914 Currently this list is not used in the SILC just yet, though there
6915 are a lot places where this can replace dynamically allocated
6916 tables and I will fix these places, later, to use SilcDList.
6917 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6918 and use TRQ internally).
6920 Also fixed some annoying warning messages that the original TRQ
6921 code generated. Also minor changes to TRQ's Makefile.in.
6923 * Added support for querying by Client ID to both WHOIS and
6924 IDENTIFY commands into server, as required by the protocol.
6926 * Removed method function pointers from SilcBuffer structure. They
6927 weren't used to anything and just increased the context size for
6928 no good reason. This change also made silc_buffer_alloc and
6929 silc_buffer_free functions inline functions.
6931 * Disabled command flooding detection support until it's fixed so
6932 that it accepts commands in but does not execute them more than once
6935 * Added silc_net_localhost(), to return local hostname, into
6936 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6937 that must be initialized before calling silc_client_init.
6939 * Added new function: silc_server_send_notify_on_channels to send
6940 notify messages to all channels client has joined. It is assured
6941 that the message is sent only once per client.
6943 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6944 lib/silcutil/silcutil.[ch] as silc_format function. The new
6945 function is generic and is used by server as well, not only by
6946 the logging routines.
6948 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6949 the provided version string was not acceptable. Added new function:
6950 silc_ske_check_version into lib/silcske/silcske.h. The function
6951 must be implemented by the application (client or server) and it
6952 does not reside in the SKE library. The function checks the version
6953 string remote end sent.
6955 * Added back pointers (to opaque context and to SilcSocketConnection)
6956 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6958 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6959 duplicate packet context structure.
6961 * Changed `notify' client operation to send same arguments as client
6962 receives from server except for ID's. ID's are mapped to correct
6963 ID entry and that is returned. Also, if channel entry is not sent
6964 by server but the notify is for channel the channel entry is sent
6965 to application (otherwise application doesn't know that it is for
6966 channel (library gets it from packet's Destination ID)).
6968 * Added silc_client_remove_from_channels into client library to
6969 remove a client from all channels it has joined to. Used when
6970 received SIGNOFF notify from server. Added also new function
6971 silc_client_replace_from_channels to replace old ID entry with
6972 new ID entry on all channels. Used when received NICK_CHANGE
6975 * Fixed ID Cache list handling in silc_idlist_get_client in
6976 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6977 to get (or query) client by ID.
6979 * Updated TODO list.
6981 * Added connection authentication status message defined by the
6982 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6983 support for these into the code in client and server side.
6985 * Added generic function silc_client_send_command to send any command
6986 with variable argument list. Application should use this function
6987 to send commands if the command functions provided by the library
6988 does not suite for the application's user interface needs.
6990 * Added new `failure' client operation. Application is notified about
6991 received failure packet if client is executing a protocol. In this
6992 case the protocol's execution has failed.
6994 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6995 is required by the protocol.
6997 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6998 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7001 * Added status flag to SilcSKE object to indicate realtime status
7002 of the SKE protocol.
7004 * Application receives now exactly same command reply arguments as
7005 the library receives from server. However, if ID is received the
7006 corresponding ID entry is returned to the application (eg. Client
7007 ID is mapped to correct SilcClientEntry entry and that is returned).
7008 Changed command_reply client operation due to this change.
7010 * Changed all ID's in commands and in command replys as ID Payloads.
7011 Change affected both client and server side codes.
7013 All ID's sent in SILC network (with execption of ID's in SILC
7014 Packet header) are sent in ID Payload to support variable length
7017 * Server now notifies nick changes and notifies all clients on
7018 the channels about the new nickname (about the new Client ID,
7021 * Implemented CMODE command to change channel modes. Supports all
7022 channel modes defined by the protocol specs except ban and invite
7023 lists. (Also, private channel key mode is supported but support for
7024 setting private channel key in client is missing, thus, this mode
7025 has no effect on client side (except that server requires that the
7026 client uses private channel key and normal channel traffic does not
7029 Also, invite mode works per se, but INVITE command does not work
7030 yet correctly, so you can set channel as invite only channel but
7031 inviting clients to the channel does not work (it is yet to be
7032 thought what's the best way to do it).
7034 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7035 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7036 Implemented CUMODE command to change user's mode on the channel.
7037 Supports all modes defined by the protocol specs.
7039 * Added NAMES command reply to return users modes on the channel.
7041 * Removed unnecessary and slow ciphers from lib/silccrypt.
7043 * Set SO_KEEPALIVE option to connection sockets by default.
7045 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7047 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7048 redefined the Notify Payload into protocol specs.
7050 * Added silc_id_payload_parse_id to get ID directly from raw
7053 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7056 accept searching by Client ID as well.
7058 * Added support for LEAVE and SIGNOFF notify types in client library.
7060 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7061 to parse ID Payload from raw data.
7063 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7065 * Added flags parameter into silc_ske_assemble_security_properties
7066 function in lib/silcske/silcske.[ch].
7068 * Changed notify client operation to fit better for notify messages
7069 sent by server. The notify payload received from server is now
7070 passed to the application (after parsing it to SilcNotifyPayload).
7071 It is application's responsibility to retrieve the arguments
7072 from the payload and show the message the way it wants. The message
7073 sent by server is implementation specific.
7075 * Changed public keys to comply with the protocol specification.
7076 Old public keys are not supported anymore and are not compatible.
7078 * Removed nickname from Channel Payload as the latest draft removed
7079 it. The client must resolve the nickname from the NAMES command
7080 reply received when it joined the channel.
7082 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7084 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7086 * Fixed some errors in protocol specification drafts.
7088 * Created lib/silccore/silcnotify.c to implement Notify Payload
7089 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7090 generic payloads described by protocol specifications. The file
7091 includes implementations for ID Payload and Argument Payload.
7093 * Changed Command Payload implementation to use the new Argument
7094 Payload. Changed command_xxxx_payload to command_payload_xxxx
7095 to comply with SILC coding conventions.
7097 * Added suppport for Argument Payload handling in Notify Payload
7098 implementation as protocol requires it. Added the new support
7099 into server and client lib as well.
7101 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7103 * Added support for multiple nicknames on same channel. [n] is
7104 added locally to the nickname if there are more than one same
7105 nicknames on the channel.
7107 * Server now sends all nicknames that matched WHOIS request.
7108 Client also shows the list received from server.
7110 * Added TOPIC command to client side. User can now set and show
7111 current topic on channel.
7113 * Added MOTD command to client and server. Also, server sends the
7114 motd when client connects to the server.
7116 * Changed version strings to comply ISO 8601.
7118 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7120 * Fixed protocol error handling in client library. It should now
7121 cope even if the SKE fails for some reason.
7123 * Made new protocol specification drafts for submitting to IETF.
7125 * Implemented TOPIC command to server in silcd/command.c.
7127 * Added two new notify types into lib/silccore/silcnotify.h:
7128 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7129 notify nickname change and topic setting/change on a channel.
7131 * API change of command_reply operation in client library. The
7132 application gets now the status type received from server as well.
7134 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7136 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7138 * Cras fixed and optimized the packet handling even further and
7139 it should work now. Minor change to the prototype of function
7140 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7142 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * Added new function into lib/silcutil/silcschedule.[ch]:
7145 silc_schedule_with_fd to select() a specified fd. The function
7146 returns after timeout expires or data arrives or goes. The
7147 function is used by packet routines to wait that all data is
7148 received from network.
7150 * Fixed data reading from network in lib/silccore/silcpacket.c.
7151 The code now assures that all data is read from the fd and then
7152 continues packet processing. This was a bug fix since the code
7153 used to drop some data in some circumstances.
7155 * Added new function into lib/silcclient/client.[ch]:
7156 silc_client_start_key_exchange to start key exchange after
7157 connection has been established to server. The code internally
7158 now uses this funtion but its main purpose was to provide it
7159 for applications that perform their own connecting. After
7160 application has created a connection it merely calls this
7161 function to start the key exchange between client and server.
7162 The library takes care of everything else after that.
7164 Updated also lib/silcclient/README to explain the usage of
7167 * Do not send to application information that connection has
7168 been established. Application gets notified it by connect
7171 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7173 * Applied cras's patch to add silc_schedule_one function. The
7174 function runs scheduler once and returns.
7176 * Fixed the scheduler after cras messed it up. The timeout
7177 handling works now as it's supposed to work.
7179 * Added into lib/silccore/ silcnotify.h to include notify
7180 message types support. Changed silc_server_send_notify*
7181 functions, in server.[ch], to support those new notify types.
7182 Added the support for the notify types into client library,
7183 as well. Added new notify client operation into ops.h in
7186 * Changed silc_server_packet_send_to_channel to send normal
7187 packets instead of just channel message packets. The function
7188 is now used to send the notify packets to channels. It is not
7189 used to send channel message packets anymore, as server never
7192 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7193 va_arg()s as it seems to require it nowadays. I guess, if SILC
7194 is compiled with older va_arg() the new code should work anyway.
7196 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7198 * Splitted core library. Core library (lib/silccore) includes
7199 now only SILC protocol specific core (and common) components.
7200 Created new utility library (lib/silcutil) that includes more
7201 generic purpose stuff. The stuff for util library was taken
7202 from the old core library. This was minor and easy split.
7204 * Created SILC Client Library (lib/silcclient) that includes
7205 implementation of the SILC client without user interface. This
7206 was major move from silc/ directory. The code has been changed
7207 so that it is transparent towards the user interface. The
7208 silc/ directory includes now the same user interface as before
7209 and it uses the new client library. Read lib/silcclient/README.
7210 Basicly, the client library performs everything else related
7211 to SILC except user interface handling. Also, configuration
7212 files are considered to be part of user interface and library
7213 does not handle them.
7215 This change also changed a lot of structures, function naming etc.
7216 Most important change was that SilcClientWindow object was
7217 renamed to SilcClientConnection in the client library. Created
7218 also new file lib/silcclient/ops.h. Also added new files
7219 silc/local_command.[ch] and silc/client_ops.[ch].
7221 All these changes were made to make it easier for user interface
7222 designers to create what ever user interface for the SILC client
7225 It is also expected that the server will be moved to lib
7226 directory as well and SILC Server Library will be created;
7227 sometimes in the future.
7229 * Removed Local commands from lib/silccore/silccommand.h as
7230 they are application specific and new client library does not
7231 handle any of those anymore.
7233 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7234 old client implementation in silc/.
7236 * Added support for callback functions in SILC_LOG_* macros.
7237 Application can now set its own callbacks that will be called
7238 instead of using the default functions that will always print
7239 the debug messages to stderr (or stdout). Also, debugging can
7240 now be disabled by setting silc_debug to FALSE and re-enabled by
7241 setting it to TRUE. Note, that logging will still work even
7242 if debugging is disabled.
7244 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7245 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7246 silc_log_reset_debug_callbacks.
7248 * To enable debugging in silc client one must give now -d
7249 option on command line.
7251 * Changed silc_schedule_init to automatically allocate task queues
7252 if they are not allocated before calling it.
7254 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7256 * Added GMP 3.1 into math library.
7258 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7260 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7261 a channel in SILC network. The packet is used by servers and
7262 routers to notify other routers that user has left a channel.
7263 This little feature was missing until now. Added the feature
7264 to protocol specification as well.
7266 Added functions: silc_server_send_remove_channel_user and
7267 silc_server_remove_channel_user into server.[ch].
7269 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7270 lib/silccore/silcpacket.h. However, they are not implemented
7273 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7275 * Fixed joining to a channel and sending channel messages
7276 between server and router. The channel message sending should
7277 now work inside a cell.
7279 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7281 * Fixed the private message sending between server and router.
7282 The private message sending should now work inside a cell.
7284 * Added silc_server_replace_id into server.[ch] to replace
7285 existing ID in the SILC network.
7287 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7288 and silc_idlist_replace_server_id into idlist.[ch] in server.
7290 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7292 * Fixed the server to server connections. Server can again now
7293 connect to router. Router to router connections probably does
7296 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7298 * Added dynamic protocol registering support. Now protocols can
7299 registered and unregistered on the fly. Patch by cras.
7301 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7303 * Added lib/contrib directory to hold routines that some platforms
7304 don't have but are needed by SILC.
7306 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7307 into lin/contrib to provide getopt() and getopt_long() for
7308 those who don't have it.
7310 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7312 * Added AWAY command to client. When away message is set and
7313 client receives a private message packet the client automatically
7314 replies to the sender with the away message.
7316 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7317 bug seemed to be the cause of recent problems when compiling
7320 * Added version detection support to SKE protocol specification
7321 and added the new changes to the SKE implementation as well.
7322 There were other minor changes in the SKE protocol as well.
7324 Many changes in lib/silcske/silcske.[ch] and in
7325 lib/silcske/payload.[ch].
7327 * Added ^U functionality, clear input line. Patch from cras.
7329 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7331 * Mainly small bugfixes on core library. Fixed some debugging
7332 logging and buffer overflow in silclog.c.
7334 * Updated config.sub and config.guess on the distribution tree.
7336 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7338 * Added command lagging support in server. Client may execute
7339 commands now only once in two seconds.
7341 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7343 * Optimized packet reception. MAC computation and checking is now
7344 also more optimized. A lot previously duplicated code is now
7345 used as generic by both client and server.
7347 * Fixed key pair generation in clientutil.c
7349 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7351 * Added into lib/silccore/silcbufutil.[ch] new function;
7352 silc_buffer_realloc.
7354 * Moved generic packet sending/encryption functions to
7355 lib/silccore/silcpacket.[ch] from client and server. Some
7356 rewriting of the functions.
7358 * Moved all generic packet reception/decryption functions to
7359 lib/silccore/silcpacket.[ch] from client and server. The
7360 packet processing is now much cleaner in both client and server.
7361 These were major changes in both client and server.
7363 * Created many common functions in server to do packet sending.
7364 Previously code were duplicated a lot, this has been removed
7367 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7369 * Rewrote major parts of the ID cache system. Don't know
7370 whether it is better now or not but at least the API is more
7373 * Major rewrite on ID cache stuff on client because of the ID
7374 cache API changes. Added idlist.c to client.
7376 * Also major rewrite on ID cache stuff on server as well.
7377 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7378 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7379 in hand, instead they are all put into the ID cache system now.
7380 All server_idlist_* routines uses ID cache now instead of
7381 traversing its own lists (those lists does not exist anymore).
7382 SilcIDList though still exists. Also, SilcXXXEntry's are
7385 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7387 * Finally made the SKE implementation compliant to the protocol
7388 specification. All mp integers are now binary encoded as
7389 opposed being HEX encoded.
7391 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7394 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7395 functions: silc_[encode/decode]_pem. Also added function
7396 silc_encode_pem_file to PEM encode with newlines ('\n') for
7399 * SILC public keys are now encoded either PEM or binary. Same
7400 option is for private keys as well. By default private keys
7401 are binary encoded and public keys PEM encoded. Silly HEX
7402 encoding were removed.
7404 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7405 function to create fingerprints.
7407 * Fixed a bug in SHA1; does not change the original data anymore.
7409 * Partly implemented INFO command on client and server side.
7410 Fixed CLEAR command. Changes to SERVER command; show current
7411 server(s) when giving command without arguments. Added
7412 VERSION command to client.
7414 * Added check to server that unregistered connections cannot
7415 execute commands (unless it is specificly allowed).
7417 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7419 * Fixed screen refresh.
7421 * Fixed channel joining bug from client. On some circumstances
7422 client tried to join to a channel it had already joined.
7424 * Added public key verification process into client's protocol.c.
7425 The client now verifies the public key from user and saves
7426 it into ~./silc/serverkeys/ directory.
7428 Added into: clientutil.[ch]: silc_client_verify_server_key.
7430 * Changed SKE protocol's silc_ske_initiator_finish function
7431 to accept callback function that verifies the received public
7432 key. Removed old silc_ske_verify_public_key function.
7434 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7436 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7437 silc_pkcs_private_key[_data]_set.
7439 * Made the password and public authentication more cleaner in
7440 server's protocol.c.
7442 * Removed historic and obsolete protocol `channel_auth' from
7443 both client and server.
7445 * Removed wrong way of sending command status messages from
7446 server to client in server's command.c. The old way violated
7447 protocol specification.
7449 Changes to silccore/silccommand.[ch]: removed
7450 silc_command_encode_status_payload -> not needed anymore,
7451 changed silc_command_encode_payload_va to accept extra
7452 argument on variable argument list. The argument type must
7453 now be provided to the function. Also, added new function:
7454 silc_command_encode_reply_payload_va which is same as
7455 normal command_encode_payload_va except command status type
7456 is provided as extra argument.
7458 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7460 * Added ~./silc directory handling. The directory includes the
7461 public and private keys for the client.
7463 Added silc_client_check_silc_dir, silc_client_create_identifier
7464 and silc_client_load_keys.
7466 * Implemented SILC protocol compliant public key. Added public
7467 and private key saving to and loading from files.
7469 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7470 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7471 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7472 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7473 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7475 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7476 silc_pkcs_load_[public/private]_key.
7478 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7480 * Added silc_server_get_route (route.[ch]) to get connection
7481 data for the fastest route for given ID.
7483 * Implemented INVITE command on client and server. The command
7484 were re-defined in the SILC Protocol Specification and the
7485 implementation now complies with the specification.
7487 * Implemented PING command on client and server.
7489 * Implemented NAMES command on client and server. The server side
7490 supports currently only normal server not router server yet.
7491 Some changes to NAMES definition in SILC protocol specification.
7493 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Implemented LEAVE command on client and server.
7497 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7498 again. This change was made to the protocol as well. Server
7499 should not violate the protocol specification anymore.
7501 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7503 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7504 was tested. SOCKS4 was not but should work anyway.
