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

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

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

288 * Added proper initializations to silc's irssi code, so it's
289 now possible to load it as module. Affected files
290 irssi/src/silc/core/silc-core.c,
291 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
293 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>

302 * ROBOdoc documented lib/silcutil/silcmemory.h.
303 Added also new function silc_memdup.
305 * Removed lib/silcutil/silcbufutil.h and moved those routines
306 to the lib/silcutil/silcbuffer.h.
308 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
310 * Added `user_count' to the SilcChannelEntry which now tells the
311 number of users on the channel. The user count is now saved
312 in normal server of global channels as well. Affected files
313 silcd/server.c, idlist.h, packet_receive.c and command.c.
315 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
316 include file utility functions.
318 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
319 instead of calling directly OS routines.

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

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

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

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

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

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

536 file lib/silcutil/silclog.c.
538 * Fixed the channel message payload decryption in the function
539 silc_channel_message_payload_decrypt to not modify the original
540 buffer before it is verified that the message decrypted
541 correctly. Otherwise, next time it is called with correct
542 channel key it won't encrypt since the payload is corrupted.
543 Affected file lib/silccore/silcchannel.c.
545 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
547 * Do not constantly resize the window. A fix patch by cras.
548 Affected file irssi/src/fe-text/screen.c.
550 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
552 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
553 Affected file lib/silcutil/silcnet.c.
555 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
557 * Fixed a bug in hash table internal routine for traversing
558 the table with foreach callback. The current entry may
559 become invalid in the callback but it was referenced after
560 the callback returned.
562 Do not allow auto rehashing of hash table during the
563 silc_hash_table_foreach operation, for same reasons as it is
564 not allowed for SilcHashTableList. Affected files are
565 lib/silcutil/silchashtable.[ch].
567 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
569 * Defined DLLAPI into silcincludes.h and silcwin32.h for
570 Win32 DLL. extern's in header files are now declared with
573 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
575 * Fixed private message handling. It used some old code that
576 caused the client to crash. Affecte file is
577 lib/silcclient/client_prvmsg.c.
579 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
581 * Added function silc_client_add_channel,
582 silc_client_replace_channel_id, and removed functions
583 silc_client_new_channel_id and silc_idlist_get_channel_by_id
586 * Added cross reference of the joined channels to the
587 SilcClientEntry, and changed the SilcChannelEntry's
588 users list to SilcHashTable. The affected files are
589 lib/silcclient/idlist.[ch].
591 * Fixed a bug in hash table tarversing. While the hash table
592 is traversed with SilcHashTableList the table must not be
593 rehashed. It is now guaranteed that auto rehashable tables
594 are not rehashed while tarversing the list. Also defined that
595 silc_hash_table_rehash must not be called while tarversing
596 the table. Added function silc_hash_table_list_reset that must
597 be called after the tarversing is over. The affected files are
598 lib/silcutil/silchashtable.[ch].
600 * Changed all hash table traversing to call the new
601 silc_hash_table_list_reset in server and in client library.
603 * Added function silc_client_on_channel to return the
604 SilcChannelUser entry if the specified client entry is joined
605 on the specified channel. This is exported to application as
606 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
608 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
610 * Fixed founder regaining problem with JOIN command on normal
611 server. The notify for mode change must be sent always and
612 not only if !cmd->pending. Affected file silcd/command.c.
614 * Fixed the WHOWAS command's reply sending to support the
615 lists correctly. Affected file silcd/command.c.
617 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
619 * When sending JOIN command to router for processing the
620 sender's old command identifier was not saved back to the
621 sender's command context, fixed now. The affected file is
624 * Create the key in JOIN command of the router did not return
625 the channel key, added check for this. Affected file is
628 * Fixed a channel ID update bug in JOIN command reply. Do
629 not directly upgrade the ID but call the function
630 silc_idlist_replace_channel_id if the ID was changed.
631 Affected file silcd/command_reply.c.
633 * Fixed memory leaks from command calling if it would fail.
634 Affected file silcd/command.c.
636 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
638 * Applied patches from cras:
640 Memory leak fixes around libaries, irssi window resize fix,
641 new silclist.h and silcdlist.h, all extern inline changed to
644 * Removed dotconf from lib/dotconf, not needed anymore.
646 * Removed TRQ from lib/trq, not needed anymore.
648 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
649 with server connections. Later this will be configurable
650 in config file after new config file is done. Affected file
653 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
655 * Fixed a crash in server related to channel announcements.
656 Affected file silcd/server.c.
658 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
660 * Fixed memory leaks in silc_server_create_new_channel*
661 functions. Affected file silcd/server.c.
663 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
664 which ID was changed. This way the router will send the
665 user list for the channel again, and server won't be in
666 desync in some rare circumstances. Affected file is
667 silcd/packet_receive.c.
669 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
671 * Check for NULL socket pointer in the function
672 silc_server_packet_send_to_channel_real. Affected file
675 * Fixed the BAN notify handling to correctly remove ban
676 list. Affected file silcd/packet_receive.c.
678 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
680 * Fixed some header addition to Toolkit distribution in
681 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
683 * Added lib/silcclient/client_ops_example.h as an template
684 file for application programmers to quickly start using
685 the SilcClientOperation functions in their application.
686 Updated the lib/silcclient/README as well to tell about this
687 nice file made available.
689 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
691 * Call silc_server_remove_from_channels when removing client
692 entry when NO_SUCH_CLIENT_ID was received. Affected file
693 is silcd/command_reply.c.
695 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
697 * Added server & router operator statistics updating. Affected
698 file silcd/packet_receive.c and silcd/command.c.
700 * Fixed the SERVER_SIGNOFF notify handling on normal server
701 not to save the history information for clients. Same was
702 fixed earlier in remove_clients_by_server function, but not
703 here. Affected file silcd/packet_receive.c.
705 * Raised the default connection-retry count from 4 to 7 in
706 server. Affected file silcd/server.h.
708 * Cancel any possible reconnect timeouts when we start the
709 key exchange. Affected file silcd/server.c.
711 * Do not reconnect on connection failure when SCONNECT was
712 given. Affected files silcd/server.[ch].
714 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
716 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
718 * Fixed the NICK command to always give the unformatted
719 nickname to the one giving the NICK command. If unformatted
720 nickname is cached already it will be formatted and the
721 local entry will always get the unformatted nickname.
722 Affected file lib/silcclient/idlist.c.
724 * Fixed some double frees from client library commands.
725 Affected file is lib/silcclient/command.c.
727 * Fixed CUMODE command in server to assure that no one can
728 change founder's mode than the founder itself, there was a
729 little bug. Affected file silcd/command.c.
731 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
733 * Removed the SilcClientCommandDestructor from the client
734 libary, it is not needed anymore. Affected files are
735 lib/silcclient/silcapi.h, command[_reply].[ch],
736 client_notify, idlist.c.
738 * Fixed GETKEY command to first resolve client, and then
739 resolve the server only if the client was not found, instead
740 of resolving both at the same time. Affected file is
741 lib/silcclient/command.c.
743 * Added silc_client_start_key_exchange_cb and lookup the
744 remote hostname and IP address before starting the key
745 exchange with server. The affected file is
746 lib/silcclient/client.c.
748 * The server's public key is now saved using the IP address
749 of the server and not the servername for the filename.
750 The hostname public key filename is checked as an fall back
751 method if the IP address based filename is not found.
753 Fixed the GETKEY command to save the fetched server key
756 Print the remote server's hostname now when new key is
757 received during connection process. Affected file is
758 irssi/src/silc/core/client_ops.c.
760 * Return always our own public key to the client if it asks
761 for it with GETKEY command. Affected file silcd/command.c.
763 * Removed the use_auto_addr variable from default config
764 file since it was in wrong section. Affected file is
767 * Fixed TOPIC_CHANGE notification to not route it when it
768 was sent using silc_server_send_notify_to_channel function.
769 Affected file silcd/command.c.
771 * Fixed silc_server_send_notify_kicked to send the kicker's
772 Client ID also, it was missing. Affected files are
773 silcd/command.c, silcd/packet_send.[ch].
775 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
777 * Do not save client history information in SERVER_SIGNOFF.
778 Fixes the bug in normal server that it does not detect
779 the client becoming valid after the server becomes back
780 online. Affected file silcd/server_util.c.
782 * Added `sock_error' field into the SilcSocketConnection
783 context. When error occurs during socket operation (read
784 or write) the error is saved. Added also new function
785 silc_socket_get_error to return human readable socket error
786 message. Affected files are lib/silcutil/silcsockconn.[ch],
787 lib/silcutil/unix/silcunixsockconn.c, and
788 lib/silcutil/win32/silcwin32sockconn.c.
790 * The server now prints the socket error message in the
791 signoff for client. Affected file silcd/server.c.
793 * Fixed the `created' channel information sending from router
794 to server in JOIN command. Checks now whether the channel
795 really was created or not and set it according that.
797 Fixed the JOIN command to use the client entry's current
798 ID during the joining procedure instead of the one it sent
799 in the command (it is checked though), since it can change
800 between the packet processing and command processing, and
801 would just case unnecessary pain in the client end. Affected
802 file silcd/command.c.
804 * Fixed a channel key payload sending to use correct channel
805 ID when the server was forced to change the channel's ID by
806 router. Router sent the key payload with the old Channel ID.
807 Affected file silcd/packet_receive.c.
809 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
811 * Call silc_server_save_channel_key only if the key payload
812 was provided in the JOIN command's command reply. Affected
813 file silcd/command_reply.c.
815 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
817 * Fixed silc_mp_sizeinbase to return the value correctly with
818 MPI. Affected file lib/silcmath/mp_mpi.c.
820 * Fixed the stop_server signal to correctly stop the scheduler
821 and gracefully stop the server when SIGTERM or SIGINT signals
822 are received. Affected file silcd/silcd.c.
824 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
826 * Simple handling of TERM and HUP signals. Also added some log
827 flushing call around. Affected file is
830 * Fixed small bugs in silclog.c. Now buffering output will take
831 effect after 10 seconds since startup: This will ensure that
832 no important startup messages are lost. Also output redirection
833 will preserve original format ([Date] [Type] message).
834 Affected file is lib/silcutil/silclog.c.
836 * Added two options to the config file, in the logging section:
837 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
838 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
840 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
842 * Do not print the warning about log files not being initialized
843 more than once to avoid excess logging. Affected file is
844 lib/silcutil/silclog.c.
846 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
847 the SIM copying in make install in Makefile.am.pre.
849 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
851 * Rewritten silclog APIs. Globally interesting changes follows:
852 silc_log_set_files() changed to silc_log_set_file().
853 silc_log_set_callbacks() changed to silc_log_set_callback().
854 ROBOdoc documented silclog header file.
855 SilcLogCb now returns bool to wether inihibit the default
856 handler or not (to keep the old behaviour return always TRUE).
857 The new APIs should also fix the problem of the
858 silcd_error.log file that was written in the current directory.
861 Log files streams will remain opened after silc_log_set_file()
862 call, means less CPU usage notably on high traffic servers.
863 File streams are now full buffered, and flushed to the disk
864 every 5 minutes, lesses HD activity and CPU usage.
865 Messages can be redirected, allowing admins to configure
866 one single logfile for all server messages.
867 the silc_log_quick global variable to activate fast-logging.
868 Affected files lib/silcutil/silclog.[ch]
870 * Changed some code to conform new silclog APIs. Affected
871 files are doc/example_silcd.conf.in, silcd/server.c
872 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
875 * Fixed a memory leak that could occur in some situations.
876 Affected file silcd/serverconfig.c.
878 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
880 * Added the silc_client_del_client to remove the client from
881 all channels as well. Affected file lib/silcclient/idlist.c.
883 * Fixed the client library to correctly remove the client
884 from all channels when the client entry is being destroyed.
885 Affected file lib/silcclient/client_notify.c, command.c.
887 * Added auto-nicking support to the client library. If the
888 applicatio now sets client->nickname it will be sent to the
889 server after connecting by the library. This way for example
890 SILCNICK (or IRCNICK) environment variables will have effect
891 and always change the nickname automatically to whatever
892 it is wanted. Affected file lib/silcclient/client.[ch].
894 * Renamed silc_server_command_bad_chars to the
895 silc_server_name_bad_chars and moved it to the
896 silcd/server_util.[ch]. Added also new function
897 silc_server_name_modify_bad to return nickname that
898 includes bad characters as new nickname without those
899 bad characters. This check and modify is now used in
900 silc_server_new_client when the username is initially set
901 as nickname, so it must be checked to be valid nickname.
902 Affected file silcd/packet_receive.c.
904 * The nickname length is now taken from the packet for real
905 and not trusted to strlen() since it clearly can return
906 wrong length for nickname including bad characters. This
907 also applies to channel names. Affected file silcd/command.c.
909 * Removed the lib/silcsilm/modules directory. Modules are now
910 compiled into the lib/silcsim. Fixed the copying of the
911 modules to follow symbolic links in Makefile.am.pre.
913 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
915 * Fixed silc_string_regexify list creation. Fixes bugs with
916 BAN and INVITE commands in server. The affected file is
917 lib/silcutil/unix/silcunixutil.c.
919 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
921 * Removed the command destructor entirely from the server's
922 command and command reply routines. It is not needed, and
923 its usage was buggy and caused crashes. Affected files are
924 silcd/command[_reply].[ch].
926 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
928 * Cancel protocol and NULL sock->protocol if timeout
929 occurred during protocol. Affected file silcd/server.c.
931 * Cancel protocol timeouts always before calling the final
932 callback, to assure that after final callback is called
933 no other state will be called for the protocol anymore.
934 Affected file silcd/protocol.c.
936 * Print error log if incoming connection configuration could
937 not be found. Affected file silcd/server.c.
939 * Fixed JOIN command to correctly save the founder mode
940 to the client on normal SILC server, when the channel
941 was created by the router. Affected file silcd/command.c.
943 * Fixed LIST command (hopefully) to send correct reply
944 packets. Affected file silcd/command.c.
946 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
948 * The silc_packet_receive_process now returns FALSE if the
949 read data was invalid packet, and TRUE if it was ok.
951 The server now checks that if unauthenticated connection
952 sends data and its processing fails the server will close
953 the connection since it could be a malicious flooder.
955 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
957 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
959 * Make sure the warning about error opening a log file is
960 printed only once and not everytime it fails (produces
961 too much useless log). Affected file lib/silcutil/silclog.c.
963 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
965 * Made the silc_server_daemonise() function more readable.
966 Affected file silcd/server.c.
968 * Pid file is now optional, the user may comment it out from
969 the config file. Removed define SILC_SERVER_PID_FILE, we
970 don't need a default any longer. Affected file
971 configure.in.pre, lib/Makefile.am.pre.
973 * Make some use of the pid file. The server now dies at startup
974 if it detects a valid pid file on his path. The server would
975 die anyway in this circumstance, because of the bind() failure.
976 Affected file silcd/silcd.c.
978 * No longer compiling lib/dotconf.
980 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
982 * Fixed JOIN command parsing not to crash. Affected file
983 lib/silcclient/command.c.
985 * Fied the NICK_CHANGE notify to add the new client entry
986 even it is resolved. This removes an <[unknown]> nick
987 thingy bug in the client. Affected file is
988 lib/silcclient/client_notify.c.
990 * Do not try to allocate 0 bytes (efence does not like it)
991 in lib/silccore/silccomand.c when encoding payload.
993 * Do not take IRCNICK as nickname in Irssi SILC client since
994 it is not possible to set nickname before hand connecting
995 the server (TODO has an entry about adding auto-nicking
998 * Changed the silc_server_command_pending to check whether
999 there already exists an pending entry with the specified
1000 command, command identifier and pending callback. This is
1001 to fix IDENTIFY and WHOIS related crashes that may register
1002 multiple pending commands with same identifier. Affected
1003 file silcd/command.c.
1005 * Fixed the server to reconnect to the router even if it
1006 was already reconnecting and EOF was received. This to
1007 fix a possibility that the server wouldn't ever try to
1008 auto-reconnect to the router. Affected file silcd/server.c.
1010 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1012 * Fixed the server's password authentication to use the
1013 length of the locally saved password, and not the one
1014 sent in the packet. Affected file silcd/protocol.c.
1016 * Fixed same password authentication problem in the
1017 Authentication Payload handling routines in
1018 lib/silccore/silcauth.c.
1020 * Yet another password authentication problem fixed with
1021 channel password handling in silcd/command.c.
1023 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1025 * If first character of string in silc_parse_userfqdn is '@'
1026 then do not parse it. Affected file is
1027 lib/silcutil/silcutil.c.
1029 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1031 * Fixed minor bug in IDENTIFY command reply sending, which
1032 caused various weird problems during JOIN when it was
1033 resolving names for users. Affected file silcd/command.c.
1035 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1037 * Fixed the IDENTIFY command reply sending to chech better valid
1038 clients. It was possible to send incomplete list of replies.
1039 Affected file silcd/command.c.
1041 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1043 * Added silc_client_command[s]_[un]register functions now to
1044 dynamically register the commands in client library. Removed
1045 the static table of commands. This allows the client library
1046 to call commands without causing the application to know about
1047 what commands library has called.
1049 Removed the INFO command reply kludge to detect when the command
1050 was called by library. Now library use its own command reply
1051 function for INFO command.
1053 Added function silc_client_command_call to call a command.
1054 Application can use it to call command, not access the structure
1057 Now all commands that are sent by the client library (not
1058 explicitly sent by application) use own command reply functions.
1060 Affected files around lib/silcclient/ and in
1061 irssi/src/silc/core/.
1063 * Fixed the WHOIS command reply sending to chech better valid
1064 clients. It was possible to send incomplete list of replies.
1066 Fixed the WHOIS and IDENTIFY to send the request to router
1067 if normal server did not do it and did not find any results.
1069 Affected file silcd/command.c.
1071 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1073 * Moved the internal data from SilcClient context into its
1074 own file, not accesible to application. Affected files
1075 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1076 and other files in client library.
1078 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1080 * Added doc/examples installation target in Makefile.am.pre.
1083 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1085 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1086 commands the found client entry will be removed from the
1087 cache, after notifying application about the error. Affected
1088 file lib/silcclient/command_reply.c.
1090 * Changed the /MSG to check for exact nickname user gave, and
1091 not let `nick' match `nick@host' if it is only one found. Now,
1092 user must type the exact nickname (like nick@host2) even if
1093 there are no more than one same nicks found. This is to avoid
1094 a possibility of sending nickname to wrong nickname since
1095 `nick' could match `nick@host'. Affected file is
1096 irssi/src/core/silc-servers.c.
1098 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1100 * Do not print "you are now server operator" or similar when
1101 giving /away command. Affected files are
1102 irssi/src/silc/core/client_ops.c, silc-servers.h.
1104 * Made the silc_server_command_pending_error_check to send
1105 the same command reply payload it received back to the
1106 original sender of the command. This way all arguments
1107 that was received by the server will be received by the
1108 client too. Affected file silcd/command.c.
1110 * Added the silc_idcache_add to return the created cache entry
1111 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1113 * Add global clients to expire if they are not on any channel.
1114 This is because normal server will never know if they signoff
1115 if they are not on any channel. The cache expiry will take
1116 case of these entries. This is done by normal servers only.
1117 The affected files are silcd/command_reply.c,
1118 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1120 * If server receives invalid ID notification for WHOIS or
1121 IDENTIFY and the ID exists in the lists, it is removed.
1122 Affected file silcd/command_reply.c.
1124 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1125 in client then client entry that it matches is searched and
1126 the nickname is printed on the screen for user. Affected
1127 file irssi/src/silc/core/client_ops.c.
1129 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1131 * Use cache entry expire time in the LIST command reply to
1132 purge old entries from the cache after the LIST command
1133 reply has been received. This way we don't have non-existent
1134 entries in the cache for too long. Affected file is
1135 silcd/command_reply.c.
1137 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1139 * If we are normal server, and we've not resolved client info
1140 in WHOIS or IDENTIFY from router, and it is global client,
1141 we'll check whether it is on some channel. If it is not
1142 then we cannot be sure about its validity and will resolve it
1143 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1144 file silcd/command.c.
1146 * Search channel by name (if possible) rather than by ID
1147 in IDENTIFY command's command reply. Affected file is
1148 silcd/command_reply.c.
1150 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1152 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1153 Updated specs and implemented it. Affected file silcd/command.c,
1154 silcd/packet_send.c and silcd/packet_receive.c.
1156 * Implemented the <founder auth> payload handling in the JOIN
1157 command. If provided all conditions for channel joining
1158 except requirement to provide correct passphrase can be
1159 overrided by the channel founder. Updated the protocol specs.
1160 Affected file silcd/command.c.
1162 Added support for founder auth in JOIN command in client
1163 library. Fixed the parsing of the JOIN command now to support
1164 all options as they should be. The affected file is
1165 lib/silcclient/command.c.
1167 * Optimized the WHOIS and IDENTIFY commands to send the request
1168 to router only if it includes nicknames or other names. If
1169 they include only IDs then check the local cache first before
1170 routing. Affected file is silcd/command.c.
1172 * Added channels topic announcements. Affected file is
1173 silcd/packet_receive.c and silcd/server.c.
1175 * Fixed the silc_server_send_notify_topic_set to really destine
1176 the packet to channel. Affected file silcd/packet_send.c.
1178 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1179 library. Affected file lib/silcclient/client_notify.c.
1181 * Added UMODE announcements. Affected file silcd/server.c.
1183 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1185 * Memory leak fixes in:
1187 lib/silcutil/silcsockconn.c
1188 lib/silcske/silcske.c
1189 lib/silcske/groups.c
1191 lib/silccrypt/silcpkcs.c
1192 lib/silccore/silccommand.c
1193 lib/silccore/silcidcache.c
1198 * ROBOdoc documented the lib/silcske/groups.h file and a
1199 bit changed the interface for better.
1201 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1203 * Update the client entry context in the ID cache after
1204 nick change. Affected file lib/silcclient/command.c.
1205 Fixes the CUMODE command when regaining founder privileges,
1206 and a little WHOIS problem.
1208 * Fixed silc_net_gethostbyname to correctly call the
1209 inet_ntop. Affected file lib/silcutil/silcnet.c.
1211 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1213 * Added IPv6 support checking to the configure.in.pre, added
1214 also --enable-ipv6 option to override the check. Affected
1215 file configure.in.pre.
1217 * The silc_thread_create now calls the start function
1218 directly if threads support is not compiled in. Removes
1219 ugly #ifdef's from generic code. Affected files are
1220 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1222 * Added silc_net_gethostby[name/addr]_async to asynchronously
1223 resolve. Affected files are lib/silcutil/silcnet.[ch].
1225 * Added support for rendering IPv6 based server, client and
1226 channel IDs. Affected file lib/silcutil/silcutil.c.
1228 * Added support for creating IPv6 based server IDs. Affected
1229 file is silcd/serverid.c.
1231 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1233 * Added silc_net_gethostby[addr/name] into the
1234 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1235 routines. Added silc_net_is_ip[4/6]. Affected file is
1236 lib/silcutil/unix/silcunixnet.c. All routines that take
1237 address as argument now supports both IPv4 and IPv6 addresses.
1239 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1241 * Fixed LIST command reply sending in server. Affected file
1244 * Server now sends the kicker's client ID in the KICK notify
1245 to the kicked client. Affected file silcd/command.c.
1247 * The client library now parses the kickers client ID and
1248 UI displays it. Affected files lib/silcclient/client_notify.c
1249 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1251 * Made all payload parsing function prototypes consistent.
1252 They all take now const unsigned char * and uint32 pair as
1253 the payload data instead of SilcBuffer. Changes all around
1254 the source tree. Other unsigned char* -> const unsigned char*
1255 changes around the tree as well.
1257 * Optimized SFTP client and server packet sending not to
1258 allocate new buffer for each packet but to recycle the
1259 first allocated buffer. Affected files are
1260 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1262 * Optimized the SFTP client to use SilcList instead of
1263 SilcDList for requests, because it is faster. Affected file
1264 is lib/silcsftp/sftp_client.c.
1266 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1267 into lib/silccore/silcid.[ch].
1269 Renamed silcpayload.[ch] into silcargument.[ch].
1271 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * If client entry is deleted with active key agreement
1274 session, abort the session.
1276 The silc_client_abort_key_agreement now calls the completion
1277 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1279 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1282 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1284 * Don't use __restrict in older GCC's. Affected file is
1285 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1287 * silc_net_localhost now attempts to reverse lookup the
1288 IP/hostname. Affected file lib/silcutil/silcnet.c.
1290 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1291 command. It can be used to gain founder privileges at
1292 the same time when joining the channel.
1294 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1295 kicker's client ID as well. Updated protocol specs.
1297 Defined that the server must send SILC_COMMAND_IDENTIFY
1298 command reply with error status to client who sent
1299 private message with invalid client ID.
1301 Updated the protocol specification.
1303 * Added silc_server_send_command_reply to send any
1304 command reply. Affected file silcd/packet_send.[ch].
1306 * Added silc_id_payload_encode_data to encode ID payload
1307 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1309 * The server now send IDENTIFY command reply with error
1310 status if client ID in private message is invalid. Affected
1311 file silcd/packet_receive.c.
1313 * Save the server key file with server's IP address in
1314 the filename instead of hostname. The affected file is
1315 irssi/src/silc/core/client_ops.c.
1317 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1322 * Added libtool support for compiling shared objects in
1323 lib/silcsim. Affected file configure.in.pre and
1324 lib/silcsim/Makefile.am. Original patch by cras.
1326 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * Pid file configuration, and server's config file fixes
1329 patch by toma. Updated CREDITS file.
1331 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1333 * Fixed silc_client_channel_message to not try to decrypt
1334 the message twice if it resolved the destination client
1335 information. This could cause of dropping one channel
1336 message. Affected file lib/silcclient/client_channel.c.
1338 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1340 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1341 lib/silcclient/client.c. This function is used when the SILC
1342 Client is run under some other scheduler, or event loop or
1343 main loop. On GUI applications, for example this may be
1344 desired to used to run the client under the GUI application's
1345 main loop. Typically the GUI application would register an
1346 idle task that calls this function multiple times in a second
1347 to quickly process the SILC specific data.
1349 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1351 * Fixed silc_server_drop() for dropping the supplementary
1352 groups as well, this could cause a security hole on some
1355 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1357 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1360 * Write PID file after dropping privileges. Added -F option
1361 to run server on foreground. A patch by debolaz.
1362 Affected files silcd/server.c, silcd/silcd.c.
1364 * Fixed MOTD to return the MOTD file server name. Affected
1365 file silcd/command.c.
1367 * Added INFO command reply handling to the Irssi SILC Client.
1368 Affected file irssi/src/silc/core/client_ops.c.
1370 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1372 * Fixed the silc_idcache_list_* routines to really support
1373 the dynamic list. Fixes a crash. Affected file is
1374 lib/silccore/silcidcache.c.
1376 * Fixed the LIST command reply to really call LIST command's
1377 pending callbacks. Affected file silcd/command_reply.c.
1379 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Update conn->local_entry->nickname after giving NICK
1382 command. Affected file lib/silcclient/command.c.
1384 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1386 * Added the [pid] option to the silcd configuration file
1388 Affected files: serverconfig.[ch] and silcd.c
1390 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Save fingerprint in WHOIS command reply in server.
1393 Affected file silcd/command_reply.c.
1395 * Fixed NICK commands pending callback registration.
1396 Affected file lib/silcclient/command.c.
1398 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1400 * Use ++server->cmd_ident when sending commands in server,
1401 instead of random number. Affected file silcd/command.c.
1403 * Fixed GETKEY command reply to call actually GETKEY pending
1404 command callbacks. Affected file silcd/command_reply.c.
1406 * A bit stricter check for nicknames. Check for same nickname
1407 in NICK command also. Affected file silcd/command.c.
1409 * Do not call INFO command everytime client ID changes, only
1410 during first connecting. Affected file lib/silcclient/client.c.
1412 * Set the new nickname only after successful command reply for
1413 NICK command is returned by server. Affected file
1414 lib/silcclient/command.c.
1416 * Remove nicknames from nicklist during server_signoff notify.
1417 Should fix /NAMES bit more. The affected file is
1418 irssi/src/silc/core/silc-channels.c.
1420 * Added `fingerprint' field to the SilcIDListData in the
1421 silcd/idlist.h to hold the fingerprint of the client's
1424 Send the fingerprint of the client's public key in WHOIS
1427 Affected files silcd/command.c, and silcd/idlist.[ch].
1429 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1430 create fingerprint from given data.
1432 * Show the fingerprint of the client's public key in WHOIS.
1433 Affected files irssi/src/module-formats.[ch] and
1434 irssi/src/silc/core/client_ops.c.
1436 * Format the multiple same nicknames also during JOIN and
1437 NICK_CHANGE notifys. Affected file is
1438 lib/silcclient/client_notify.c.
1440 * Do not print error on screen for invalid private message
1441 payload since it can come if someone is sending private
1442 messages with wrong key. Affected file
1443 lib/silccore/silcprivate.c.
1445 * Fixed multiple concurrent /PING crash. Affected file
1446 lib/silcclient/command.c.
1448 * Changed the wrong ID encoding. All IP addresses must be
1449 in MSB first order in encoded format. They were encoded
1450 wrong and was in LSB format. Affected files are
1451 silcd/serverid.c, lib/silcutil/silcutil.c.
1453 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1455 * Call the `connect' client operation through the scheduler
1456 in case of error. Affected file lib/silcclient/client.c.
1458 * Call the `failure' client operation even if the error
1459 occurred locally during a protocol. Affected file is
1460 lib/silcclient/protocol.c.
1462 * Added support of sending LIST command to router from normal
1463 server. This way normal server can get list of all channels
1464 in the network too. Fixed the channel list sending in the
1465 server too. Affected files are silcd/command.c, and
1466 silcd/command_reply.[ch].
1468 * Added silc_server_update_channels_by_server and
1469 silc_server_remove_channels_by_server. They are used during
1470 disconnection of primary router and in backup router protocol.
1471 Affected file silcd/server_util.[ch], silcd/server.c and
1472 silcd/server_backup.c.
1474 * Fixed channel adding to global list in IDENTIFY command
1475 reply in server. Affected file silcd/command_reply.c.
1477 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * If the incoming packet type is REKEY or REKEY_DONE process
1480 that packet always synchronously. Fixes yet another MAC
1481 failed error on slow (dialup) connections. Affected file
1482 lib/silcclient/client.c and silcd/server.c.
1484 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1486 * Call check_version SKE callback for initiator too. Affected
1487 file lib/silcske/silcske.c.
1489 * Implemented fix for security hole found in the SKE that was
1490 fixed in the specification few days back; the initiator's
1491 public key is now added to the HASH value computation.
1492 Added backwards support for the old way of doing it too, for
1493 old clients and old servers. Affected file is
1494 lib/silcske/silcske.c.
1496 * Enabled mutual authentication by default in SKE. If initiator
1497 is not providing mutual authentication the responder will
1498 force it. This will provide the proof of posession of the
1499 private key for responder. The affected files are
1500 lib/silcclient/protocol.c and silcd/protocol.c.
1502 * Do not cache anymore the server's public key during SKE.
1503 We do mutual authentication so the proof of posession of
1504 private key is done, and if the server is authenticated in
1505 conn auth protocol with public key we must have the public
1506 key already. Affected file silcd/protocol.c.
1508 * Added new global debug variable: silc_debug_hexdump. If
1509 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1510 file lib/silcutil/silclog.[ch].
1512 * Fixed compilation warning due to char * -> const char *.
1513 Affected files lib/silcutil/silcnet.h, and
1514 lib/silccore/silcauth.[ch].
1516 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1518 * Fixed CMODE command when new channel key was created. If
1519 the creation failed the old key was removed. Next time giving
1520 same command would crash the server since the old key was
1521 freed already. Affected file silcd/command.c.
1523 * Fixed the silc_server_announce_get_channels to not crash
1524 on reconnect. Affected file silcd/server.c.
1526 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Added silc_log_set_debug_string function to set a regex
1529 string to match for debug output. Only the function names,
1530 or filenames matching the given debug string is actually
1531 printed. This way it is possible to filter out those debug
1532 strings that user is not interested in.
1534 Fixed a bug in silc_string_regexify.
1536 Affected files lib/silcutil/silclog.[ch], and
1537 lib/silcutil/unix/silcunixutil.c.
1539 * Changed the -d options in both server and Irssi SILC client
1540 to take the debug string as argument. Affected files
1541 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1543 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1545 * Added silc_hash_babbleprint to create a Bubble Babble
1546 Encoded fingerprint. The encoding is developed by Antti
1547 Huima (draft-huima-babble-01.txt), and it creates human
1548 readable strings out of binary data. Affected file
1549 lib/silccrypt/silchash.[ch].
1551 * Print the babble print now in addition of fingerprint as well
1552 in Irssi SILC client. Affected files are
1553 irssi/src/fe-common/silc/module-formats.[ch],
1554 irssi/src/fe-common/silc/core/client_ops.c.
1556 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1558 * Fixed a security problem found in SKE. The initiator's
1559 public key too is now added to the HASH hash value creation
1560 which is signed by the responder to create the SIGN value.
1561 This will prevent anyone in the middle to lie to the responder
1562 about the initiator's public key. If this is done now, the
1563 man in the middle will get caught. Updated the protocol
1566 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1568 * Better installation directory handling. Configure module
1569 paths and other paths automatically to example_silc* files
1570 in doc/. A patch by toma.
1572 * Fixed compiler warning from MPI library, and from SILC RNG.
1575 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1576 It can be configured with ./configure. A patch by toma.
1578 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1580 * Find correct make to use in prepare-clean. A patch by
1581 toma. Affected file prepare-clean.
1583 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1585 * Added irssi variables use_auto_addr, auto_bind_ip,
1586 auto_bind_port and auto_public_ip.
1588 * Changed the interface for silc_client_send_key_agreement
1589 in lib/silcclient/silcapi.h
1593 irssi/src/silc/core/silc-core.c
1595 lib/silcclient/silcapi.h
1596 irssi/src/silc/core/silc-channels.c
1597 lib/silcclient/client_keyagr.c
1600 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1602 * Added silc_pkcs_public_key_compare to compare two
1603 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1605 * Check that the client who set the founder mode on the
1606 channel is the same client that is giving the founder
1607 mode to itself. It is done by comparing the saved public
1608 key (it is saved even in the authentication is passphrase).
1609 Affected file silcd/command.c.
1611 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Do not process packet for disconnected socket connection.
1614 Affected file lib/silccore/silcpacket.c.
1616 * Process the DISCONNECT packet through scheduler in the
1617 client library. Affected file lib/silcclient/client.c.
1619 * Fixed the silc_client_packet_parse to not to increase
1620 the packet sequence number if the conn->sock and the
1621 current socket connection is not same. This can happen
1622 for example during key agreement when the conn includes
1623 multiple socket connections (listeners). Affected file
1624 lib/silcclient/client.c.
1626 * The sender of the file transfer request now provides also
1627 the pointer (listener) for the key exchange protocol. If
1628 the listener cannot be created then it sends empty key
1629 agreement and lets the receiver provide the listener.
1631 Added `local_ip' and `local_port' arguments to the
1632 silc_client_file_send. If they are provided they are used,
1633 if not then it will attempt to find local IP address, if
1634 not found or bind fails then the remote client will provide
1637 Affected files are lib/silcclient/client_ftp.c and
1638 lib/silcclient/silcapi.h.
1640 * Extended the FILE SEND command to support defining the

1647 of the client's public key (if the proof of posession of the
1648 corresponding private key is verified by the server).
1649 Updated to the protocol specification.
1651 * Added support of receiving the client's public key's
1652 fingerprint in command reply in client library. Affected
1653 file is lib/silcclient/command_reply.c, and
1654 lib/silcclient/idlist.[ch].

1713 preserve the WHOWAS info for the client. Affected file
1714 silcd/server_util.c.
1716 * Fixed SERVER_SIGNOFF notify handling in the server. The
1717 server is now able to process incoming SERVER_SIGNOFF notify
1718 for a server that it doesn't even know about. It will remove
1719 the clients provided in the notify. Affected file
1720 silcd/packet_receive.c.
1722 * Check for partial packet in data queue after every packet that
1723 was found from the queue. Return and wait for more data if
1724 there is partial data in queue. Affected file is
1725 lib/silccore/silcpacket.c.
1727 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1742 irssi/src/fe-common/silc/module-formats.[ch].
1744 * Wrote a help file for FILE command.
1746 * Added silc_rng_global_get_byte_fast to get not-so-secure
1747 random data as fast as possible. Random data is read from
1748 /dev/urandom if available and from the SILC RNG if not
1749 available. It is used in padding generation. Affected file
1750 lib/silccrypt/silcrng.[ch].
1752 * All packets in client library are now processed synchronously.
1753 Optimized packet processing a lot. Affected file
1754 lib/silcclient/client.c.

1765 * Assure that silc_client_notify_by_server_resolve does not
1766 resolve the client information multiple times. If it cannot
1767 be found by the first it cannot be found at all. Affected
1768 file lib/silcclient/client_notify.c.
1770 * Fixed WHOWAS command reply calling. Affected file
1771 lib/silcclient/command_reply.c.
1773 * Removed all references to silc_idlist_get_client from the
1774 Irssi SILC client since that call is internal call used by
1775 the library. The Irssi SILC client will use now client
1776 retrieval functions found in silcapi.h.
1778 * Fixed a bug in resolving nickname info before sending
1779 private message. It used freed memory. Affected file
1780 irssi/src/silc/core/silc-servers.c.
1782 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1784 * Assure my_channels statistics cannot go negative in server.
1785 Affected files silcd/server.c, silcd/server_util.c.

1801 * Added silc_net_localip to return local host's IP address.
1802 Affected file lib/silcutil/silcnet.[ch].
1804 * If key exchange or rekey protocol is active for a connection
1805 parse all packets syncronously since there might be packets
1806 in packet queue that we are not able to process without first
1807 processing packets before them. Affected file silcd/server,
1808 lib/silcclient/client.c.
1810 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1811 whether library should continue processing the packet.
1812 Affected file lib/silccore/silcpacket.h.

1858 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1859 is incomplete and is being resolved, it won't be resolved
1862 Make sure also that USERS command reply does not resolve
1863 twice information. Affected file is
1864 lib/silcclient/command_reply.c.
1866 Make sure that silc_client_get_clients_by_list does not
1867 resolve twice same information.
1869 * Check for valid client->id in the silc_server_free_client_data.
1870 Affected file silcd/server.c.
1872 * Fixed /GETKEY nick@server not to crash if the server entry
1873 is not found. Affected file lib/silcclient/command.c.
1875 * Fixed the silc_server_check_cmode_rights to check the
1876 requested modes correctly. Affected file silcd/command.c.

1881 Affected file silcd/command.c.
1883 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1885 * Call the silc_server_udpate_servers_by_server in the
1886 primary router that comes back online in the backup resuming
1887 protocol. Otherwise it routes packets wrong. Affected file
1888 silcd/server_util.[ch], silcd/server_backup.c.
1890 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1893 lib/silcutil/silcbuffmt.[ch].
1895 * Redefined the SILC packet header to include the padding
1896 length. Affected file lib/silccore/silcpacket.[ch].
1898 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1899 length for maximum padding up to 128 bytes). Affected
1900 file lib/silccore/silcpacket.h.
1902 * Removed all backwards support for old 0.5.x MAC thingies.
1903 The SILC packet header change makes it impossible to be
1904 backwards compatible.
1906 * Send the ENDING packet with timeout in the backup resuming
1907 protocol. This is to assure that all routers has connected
1908 to the primary router. Affected file silcd/server_backup.c.
1910 * Changed the RNG to take the first IV from random data. It
1911 used to take it from zero actually. Changed the RNG also
1912 to use /dev/urandom during session. /dev/random is used
1913 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1915 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * Changed the SILC packet header to have the first two bytes
1918 (the packet length) encrypted. Affected files aroung the
1919 code tree, lib/silccore/silcpacket.[ch]. Removed the
1920 SilcPacketCheckDecrypt callback. It is not needed anymore
1921 since the silc_packet_receive_process will determine now
1922 whether the packet is normal or special.
1924 * Implemented the unidirectional MAC keys. Affected files
1925 lib/silcske/silcske.c, silcd/protocol.c and
1926 lib/silcclient/protocol.c.
1928 * Implemented the packet sequence number to the MAC computation.
1929 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1930 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1931 lib/silcclient/protocol.c.
1933 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * Allow backup router to announce servers. All servers
1936 announced by backup router are added to the global list
1937 automatically. Update hte server's socket to our primary
1938 router also when backup router announces a server.
1939 Affected file silcd/packet_receive.c.
1941 * Do not update the client->router in the function
1942 silc_server_udpate_clients_by_server if the client is on
1943 global list. We might fail to find any specific server
1944 for locally connected clients and local cell clients. They
1945 should still use the `from' and not `to' as client->router.
1946 This fixes backup router resuming protocol. Affected file
1947 silcd/server_util.c.
1949 * Decrease channel statistics count only if the channel
1950 deletion worked. Affected files are silcd/server.c and
1951 silcd/server_util.c.
1953 * Added silc_server_update_servers_by_server to update origin
1954 of all server entries. Used during backup router protocol.
1955 Affected files silcd/server_util.[ch], silcd/server.c. and
1956 silcd/backup_router.c.
1958 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1959 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1960 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1961 lib/silccrypt/silchmac.c.
1963 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * Assure that router cannot reroute the same channel message
1966 to the sender. Affected file silcd/packet_receive.c.
1968 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * Made better checks that the channel message is not sent
1971 to the router it came from. Affected file is
1972 silcd/packet_send.c. Fixed memory leak too.
1974 * Announce informations for incoming router connection, but
1975 only after checking if it is replaced by backup router.
1976 Affected file silcd/packet_receive.c.
1978 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1980 * Fixed the backup resuming protocol to work in multiple
1981 router environment. Affected file silcd/server_backup.c.
1983 * Route packet only to one router in the function
1984 silc_server_packet_send_to_channel. Affected file is
1985 silcd/packet_send.c.
1987 * Fixed silc_server_send_notify_dest to set the broadcast
1988 flag. Fixed the silc_server_send_notify_topic to actually
1989 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1990 Affected file silcd/packet_send.c.
1992 * Changed the SFTP Filesystem interface. Changed the
1993 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1994 the filesystem operation function. The SilcSFTPFilesystem
1995 is now a context that is allocated by all filesystem allocation
1996 functions and it already includes the operations structure
1997 and filesystem specific context. It is given as argument
1998 now to the silc_sftp_server_start. This made the interface
1999 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2000 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2002 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2004 * Changed the backup router adding and getting interfaces
2005 in the server. The router that will be replaced by the
2006 specified backup router is now sent as argument. Affected
2007 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2010 * Added silc_net_addr2bin_ne to return the binary form of
2011 the IP address in network byte order. Affected files
2012 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2014 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * Check for existing server ID in silc_server_new_server
2017 and in silc_server_connect_to_router_final and remove the
2018 old entry if it exists. Affected file silcd/packet_receive.c,
2021 * Send the channel message always to only one router, either
2022 in upstream or downstream. Affected file is
2023 silcd/packet_send.c.
2025 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * Wrote the definition of the backup resuming protocol to the
2028 protocol specification.
2030 * Removed one redundant channel key generation from normal
2031 server during joining procedure. Removed one redundant
2032 channel key sending from server to router during joining
2033 procedure. Affected file silcd/command.c.
2035 * Made minor bugfixes to the backup router resuming protocol.
2036 Affected file silcd/server_backup.c, server.c.
2038 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Added --disable-asm configuration option. Affected files
2041 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2044 * Implemented the backup resuming protocol that is used to
2045 resume the primary router position in the cell after the
2046 primary router comes back online. Affected files
2047 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2048 and silcd/server_util.[ch].
2050 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2052 * Sleep two (2) seconds after sending QUIT command to server.
2053 Affected file lib/silcclient/command.c.
2055 * Assure that if outgoing data buffer is pending do not force
2056 send any data. Affected file silcd/packet_send.c.
2058 * Assure that if outgoing data buffer is pending do not force
2059 send any data. Affected file lib/silcclient/client.c.
2061 * Implemented the backup router support when the primary router
2062 goes down. The servers and routers can now use the backup
2063 router as new primary router without loosing connectivity.
2065 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2068 in the server to indicate disabled entry. All data read
2069 from the connection will be ignored and no data is sent
2070 for entry that is disabled. Affected files are
2071 silcd/idlist.h, silcd/server.c.
2073 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2075 * Created SFTP client and server test programs in the
2076 lib/silcsftp/tests directory.
2078 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2080 * Implemented memory filesystem (virtual filesystem) for
2081 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2084 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2086 * Implemented the SFTP (SSH File Transfer Protocol) to the
2087 lib/silcsftp. It includes SFTP client and SFTP server
2090 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2092 * Moved lib/silccore/silcprotocol.[ch] to the
2093 lib/silcutil library.
2095 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2096 take variable argument list pointer as argument. Affected
2097 file lib/silcutil/silcbuffmt.[ch].
2099 * Added silc_buffer_set function that is used to set data
2100 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2101 Affected file lib/silcutil/silcbuffer.h.
2103 * Changed various routines in the core library to use the new
2104 silc_buffer_set instead of allocating new buffer only for
2107 * Added 64-bit value formatting and unformatting support to the
2108 silc_buffer_[un]format routines. Affected file is
2109 lib/silcutil/silcbuffmt.[ch].
2111 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2112 to includes/bitmove.h.
2114 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2116 * Fixed channel user mode saving in client library. Affected
2117 file lib/silcclient/command[_reply].c.
2119 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2121 * Defined the file transfer to the SILC Protocol. Added
2122 new packet type SILC_PACKET_FTP and defined File Transfer
2123 Payload. The mandatory file transfer protocol is SFTP
2124 (SSH File Transfer Protocol). Affected file in addition
2125 of the internet draft is lib/silccore/silcpacket.h.
2127 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2128 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2129 is used as part of backup router protocol when the primary
2130 router of the cell is back online and wishes to resume
2131 the position as primary router.
2133 * Redefined the MAC generation keys in the protocol. The
2134 same key is not used anymore in both direction. Both
2135 direction will now use different keys for sending and
2136 receiving. This fixes a potential security flaw. This
2137 change causes incompatibilities in the protocol.
2139 * Redefined also the MAC computation from the packet.
2140 An packet sequence number is now added to the MAC
2141 computation. This prevents possible replay attacks against
2142 the protocol. This change too causes incompatibilities
2145 Added `sequence' field to the SilcPacketContext to hold
2146 the current sequence number for the packet.
2148 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * Added `created' field to the SilcIDListData in the file
2151 silcd/idlist.h to indicate the time when the entry was
2154 * Added `created' field to the SilcChannelEntry too. Affected
2155 file silcd/idlist.h.
2157 * Added `creation_time' aguments to all the announcement functions
2158 in the server. If it is provided then only the entries that
2159 was created after the provided time frame are actually
2160 announced. Affected file silcd/server.[ch].
2162 * The protocol says that the Channel ID's IP address must be
2163 based on the router's IP address. Added check for this in
2164 the silc_server_new_channel when processing incoming New Channel
2165 Payload. Affected file silcd/packet_receive.c.
2167 * Print out the correct version with --version in SILC client.
2168 Affected file irssi/src/silc/core/silc-core.c.
2170 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2172 * Fixed WHOWAS command to check for completnes of the client
2173 entry always, not just when the command is coming from client.
2174 Affected file silcd/command.c.
2176 * Added new function silc_server_packet_queue_purge to purge the
2177 outgoing data queue to the network. After the function returns
2178 it is guaranteed that the outgoing packet queue is empty.
2179 Affected file silcd/packet_send.[ch].
2181 * Purge the outgoing packet queue in the rekey protocol's final
2182 callback to assure that all rekey packets go to the network
2183 before quitting the protocol. Affected file silcd/server.c.
2185 * Added silc_client_packet_queue_parse as similar function as
2186 in server to the client library. The affected file is
2187 lib/silcclient/client.c.
2189 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2191 * Splitted silcd/server.c and created silcd/server_util.[ch]
2192 for utility functions.
2194 * Added new socket flag SILC_SF_DISABLED to indicate that the
2195 connection is open but nothing can be sent to or received from
2196 the connection. Affected file lib/silcutil/silsockconn.[ch].
2197 The checking for disabled socket is checked in the low level
2198 silc_socket_write and silc_socket_read functions.
2200 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2202 * Allow only nicknames and channel names that fits into the
2203 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2205 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2207 * When processing JOIN command reply in server check that if
2208 the channel exists in our global list we'll move it the local
2209 list. Affected file silcd/command_reply.c.
2211 * Fixed the check whether client is joined on the channel already
2212 in JOIN command. Affected file lib/silcclient/command.c.
2214 * Fixed the JOIN command reply to check whether the channel
2215 already exists. Affected file lib/silcclient/command_reply.c.
2217 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2219 * Added silc_ske_status_string to map the SKE error numbers
2220 to readable strings. The affected files are
2221 lib/silcske/silcske[_status].[ch].
2223 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2225 * Do not show the private channels on the WHOIS channel list
2226 as it is not allowed by the protocol. The affected file is
2229 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * Assure that the packet length digged from the actual packet
2232 is something sensible in the silc_packet_decrypt_rest_special
2233 in lib/silccrypt/silcpacket.c.
2235 * Free and NULL the allocated pointer in silc_hmac_alloc if
2236 the HMAC allocation fails. The affected file is
2237 lib/silccrypt/silchmac.c.
2239 * Print the selected security properties to the log files in
2240 the server. Affected file silcd/protocol.c.
2242 * Add SKE's reference counter even if calling the completion
2243 callback manually. Otherwise it goes negative, although it
2244 does not cause any problems. The affected file is
2245 lib/silcske/silcske.c.
2247 * Remove the client entry with short timeout after giving the
2248 KILL command. Affected file lib/silcclient/command.c.
2250 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2251 case all found clients are already disconnected (WHOWAS would
2252 found them) in the server. Affected file silcd/command.c.
2254 * Update the last_receive (time of last data received) to be
2255 updated only when received private or channel message so that
2256 the idle time showed in WHOIS makes more sense.
2258 * Added boolean field `valid' in to the SilcClientEntry in the
2259 client library to indicate whether the entry is valid or not.
2260 This fixes the nickname change bug on channel when changing
2261 the nickname to be same than the old (like nick to Nick) the
2262 nickname formatter doesn't set the new nick anymore to Nick@host.
2263 Affected file lib/silcclient/idlist.[ch].
2265 * Now actually fixed the nickname changing on disconnection.
2266 Added new function silc_change_nick to the Irssi SILC Client.
2267 Affected file irssi/src/silc/core/client_ops.c,
2268 irssi/src/silc/core/silc-nicklist.[ch].
2270 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2272 * Check that the public key exists in the GETKEY command before
2273 trying to encode it. Affected file silcd/command.c.
2275 * Print some notifications on received public keys with GETKEY
2276 command in the Irssi SILC Client. Affected files are
2277 irssi/src/fe-common/silc/module-formats.[ch],
2278 irssi/src/silc/core/client_ops.c.
2280 * Use IDENTIFY command to resolve the server information in the
2281 GETKEY command instead of INFO command. Affected file
2282 lib/silcclient/command.c.
2284 * All command reply functions in the client library now calls
2285 the pending command reply callbacks even if an error has
2286 occurred. The server has done this a long time and now it was
2287 time to move the client library to this as well. Now all
2288 errors can be delivered back to the pending command reply
2289 callbacks if necessary. Affected files are
2290 lib/silcclient/command[_reply].[ch].
2292 * Change the nickname on disconnection back to the username
2293 because in reconnect the server will enforce it to it anyway.
2294 Affected file irssi/src/silc/core/silc-servers.c.
2296 * Fixed a config file parsing bug in the Irssi SILC client.
2297 Affected file irssi/src/silc/core/clientconfig.c.
2299 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * When printing the channel mode on JOIN, verify that the
2302 channel key and channel's HMAC are valid. Affected file
2303 irssi/src/silc/core/client_ops.c.
2305 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2308 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2309 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2311 * Removed channel key rekey task deleting from the function
2312 silc_server_save_channel_key. Affected file silcd/server.c.
2313 Added explicit timeout task context instead that is used to
2314 delete the task if we are registering a new task before the
2315 new task has elapsed.
2317 * When channel key rekey occurs the client library now saves
2318 the old channel key for a short period of time (10 seconds) and
2319 is able to use it in case some is still sending channel
2320 messages encrypted with the old key after the rekey. Affected
2321 file lib/silcclient/[idlist.h|client_channel.c].
2323 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2325 * Added check to the silc_server_new_id_real to not accept
2326 new ID if it is the sender's own ID. Affected file is
2327 silcd/packet_receive.c.
2329 * Assure that we do not announce ourself or the one we've
2330 sending our announcements when we're router and are announcing
2331 servers to our primary router. Affected file silcd/server.c.
2333 * Fixed silc_server_command_identify_check_client to assemble
2334 correct WHOIS packet. It send corrupted WHOIS packet and
2335 caused problem with router to router connections. Affected
2336 file silcd/command.c.
2338 Fixed also silc_server_command_whois_check the same way
2339 as for the IDENTIFY command.
2341 * Added new SilcIDListStatus to the server in the SilcIDListData
2342 structure. The status now includes the current status of
2343 the entry (like registered, resolved etc.). Affected file
2344 silcd/idlist.[ch]. Defined a bunch of different status types
2345 as well. This replaced the old boolean registered field as well.
2347 Added resolve_cmd_ident field to the SilcClientEntry structure
2348 too so that if the entry is for example being resolved so
2349 another command may attach to the same pending command reply
2350 without requiring to resolve the same entry again. This concept
2351 should optimize the WHOIS and the IDENTIFY resolving under
2352 heavy load by taking away unnecessary resolving for entries
2353 that are being resolved already.
2355 Added support for adding multiple pending commands for one
2356 command idenfier. Affected file silcd/command[_reply].[ch].
2358 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2359 before deleting the data. Otherwise the hash table will have
2360 freed data in comparison functions. Affected file is
2361 silcd/command_reply.c.
2363 * Fixed silc_idlist_replace_client_id to add the new entry to
2364 the cache with NULL nickname. Otherwise there will be invalid
2365 memory as the nickname after the nickname is freed. Affected
2366 file silcd/packet_receive.c.
2368 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2369 saved into wrong slots because the previous number of entries
2370 was not taken into account. Affected file silcd/idlist.c.
2371 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2373 * If we are router and we receive JOIN notify to a channel that
2374 does not have any users then notified client is marked as the
2375 channel founder, as it is it. The affected file is
2376 silcd/packet_receive.c
2378 * Added to the extended hash table API's table_del_*ext functions
2379 the destructor as argument too, so that the caller can decide
2380 which destructor to use or whether to use destructor at all.
2381 Affected file lib/silcutil/silchashtable.[ch].
2383 * Fixed ID Cache purging. It actually deleted the entries from
2384 the hash table after the data was freed. The hash table ended
2385 up comparing freed memory. The affected file is
2386 lib/silccore/silcidcache.c.
2388 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2390 * Fixed Irssi SILC client's KILL command's HELP syntax.
2392 * The USERS command now resolves the detailed user information
2393 if the userinfo field is missing. Affected file is
2394 lib/silcclient/command_reply.c.
2396 * Do not print error in silc_file_read if the read file does
2397 not exist. Just silently return NULL. Affected file is
2398 lib/silcutil/silcutil.c.
2400 * Fixed the silc_log_output to not wine about NULL filename
2401 and to not create some bogus " " filename. Affected file is
2402 lib/silcutil/silclog.c.
2404 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2406 * Fixed various printing bugs on the user interface in the
2407 Irssi SILC Client. Minor changes that were forgotten from
2410 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2412 * Fixed the configure.in.pre and the compilation and distribution
2413 environment to support the new autoconf 2.52. That version is
2414 now required to compile the CVS trunk.
2416 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2418 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2419 to generally parse user@fqdn format strings. Affected file
2420 lib/silcutil/silcutil.c.
2422 * Added nickname_format and nickname_force_format fields to the
2423 SilcClientParams structure. The first one defines the format
2424 for the nicknames that the library will enforce if the receives
2425 multiple same nicknames. The second one is boolean value and
2426 can be used to force the library to always enforce the format
2427 to the nicknames regardles whether there are multiple nicknames
2428 or not. This configurable formatting was employed to flexibly
2429 support accessing multiple nicknames from the user interface.
2430 The userinterface can now set the nicknames to what ever format
2431 they prefer. Affected file lib/silcclient/silcapi.h.
2433 Added function silc_client_nickname_format to the file
2434 lib/silcclient/idlist.c. It performs the nickname formatting.
2436 Added new field `hostname´ to the SilcClientEntry context.
2437 It holds the hostname of the client. Affected file is
2438 lib/silcclient/idlist.h.
2440 * Irssi SILC Client sets the nicknames in nick@hostn format.
2441 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2442 irssi/src/silc/core/silc-core.c.
2444 The WHOIS printing now also shows both the real nickname and
2445 the formatted nickname so that user knows how to access the
2446 user if there are multiple same nicknames cached. Affected
2447 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2448 printing formatting too to take the hostname now as a separate
2449 argument. The Affected file is
2450 irssi/src/fe-common/silc/modules-formats.[ch].
2452 * Changed the silc_client_get_clients_local to accept the formatted
2453 nickname as argument. It accepts the real nickname too but the
2454 formatted nickname can be used to find the true entry from
2455 multiple entries. Affected file lib/silcclient/silcapi.h and
2456 lib/silcclient/idlist.c.
2458 * Added nickname_format_parse field to the SilcClientParams.
2459 It is a callback function provided by the application to parse
2460 the nickname out of the formatted nickname string. The library
2461 calls it to get the nickname from the formatted string. Since
2462 the application generally knows better the format of the nickname
2463 string it parses it instead of the library, even though library
2464 encodes the formatted string. If the callback function is not
2465 provided then the library will use the string as is. The
2466 affected file is lib/silcclient/silcapi.h.
2468 * All the nickname strings passed to the client library in
2469 commands are now expected to be formatted nickname strings.
2470 If the command does not support the formatted nickname string
2471 it will assume that the sent string is the actual nickname.
2472 Affected file lib/silcclient/command.c.
2474 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Added public key authentication support to OPER and SILCOPER
2477 commands in the client library. Affected file is
2478 lib/silcclient/command.c.
2480 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2482 * Changed the get_auth_methdod client operation to be asynchronous.
2483 It can be async if the application resolves the authentication
2484 method from the server during the negotiation. Added new
2485 SilcGetAuthMeth completion callback that the application will
2486 call after resolving the authentication method.
2488 Added function silc_client_request_authentication_method that
2489 the application can use to resolve the authentication method
2490 from the server. Added also SilcConnectionAuthRequest callback
2491 that the library will call after the server has replied. The
2492 application can call this function if it does not know the
2493 current authentication method.
2495 Affected files are lib/silcclient/client.c and
2496 lib/silcclient/silcapi.h.
2498 * The Irssi SILC client now automatically resolves the authentication
2499 method incase any configuration information is not present (and
2500 currently there never is). The affected file is
2501 irssi/src/silc/core/client_ops.c.
2503 * Fixed public key authentication from the client library.
2504 Affected file lib/silcclient/protocol.c. Changed also the
2505 protocol specification about the public key authentication in
2506 the connection authentication protocol. The actual data to be
2507 signed is now computed with a hash function before signing.
2509 * Fixed the public key authentication from the server as well.
2510 Affected file silcd/protocol.c.
2512 * Removed the mlock()'s from the memory allocation routines.
2513 Affected file lib/silcutil/silcmemory.c. The ./configure does
2514 not check anymore for the mlock(). Affected file is
2517 * Fixed USERS command in server to allow the execution of the
2518 command for private and secret channels if the client sending
2519 the command is on the channel. Affected file silcd/command.c.
2521 * Fixed silc_client_get_clients_local to return the clients
2522 count correctly. It could return wrong value. Affected file
2523 lib/silcclient/idlist.c.
2525 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2528 types. The assembler optimizations seemed not to like 64-bit
2529 data types. The assmebler optimizations thus are now enabled
2530 also for BSD systems as opposed to only enable them for Linux.
2532 * Do not check for threads at all on BSD systems. Affected
2533 file configure.in.pre.
2535 * Removed -n and -h options from the Irssi SILC Client since
2536 they are not used in silc.
2538 * Fixed the prime generation to assure that the first digit
2539 of the generated random number is not zero since our conversion
2540 routines does not like number strings that starts with zero
2541 digit. If zero digit is seen the random number is regenerated.
2542 This caused some corrupted RSA keys when the zero first digit
2543 was met. Affected file lib/silcmath/silcprimegen.c.
2545 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Fixed WIN32 configuration in the ./configure script.
2548 Fixed to include xti.h on environments that has it.
2549 Patches by Carsten Ilchmann and andrew.
2551 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2553 * Changed the silc_id_create_client_id to be collision
2554 resistant. It is now assured that there cannot be created
2555 two same client ID's. I suspect that some weird bugs in
2556 the server were actually caused by duplicate Client IDs.
2557 Affected file silcd/serverid.[ch]. A router receiving
2558 new ID now also assures and informs the sending server
2559 if the ID caused collision.
2561 * Changed the silc_id_create_channel_id to also assure that
2562 there are no collisions.
2564 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2566 * Statement about ignoring the Mutual Authentication flag when
2567 performing rekey with PFS was a bit misleading. It is ignored
2568 if it was set in the initial negotiation, it cannot be even
2569 set in the rekey. Fixed in the ke-auth draft. Started the
2570 new versions of the protocol drafts in the doc/.
2572 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2574 * Fixed a bug in silc_client_command_identify_save when saving
2575 new channel information. The channel name was no duplicated
2576 and caused crash on exit. Affected file is
2577 lib/silcclient/command_reply.c.
2579 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Fixed the getkey command handling in the server. Send just
2582 empty OK reply to the sender if the key could not be fetched
2583 (but everything else was ok, like the key just was not available).
2584 Changed the public key parameter to optional in the protocol
2585 specs so that empty OK reply can be sent. Affected file
2588 Added a message to Irssi SILC client to tell to user if the
2589 server did not return a public key.
2591 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Fixed a channel key regeneration bug. It registered new
2594 timeout tasks exponentially until all system resources were
2595 used. Affected file silcd/server.c.
2597 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * Added the SILC Document generator to the scripts/silcdoc.
2600 It can be used to generate the Toolkit Reference Manual out
2601 of the source tree. Internally it will also use the RoboDoc
2602 generator now imported in util/robodoc.
2604 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * Added couple of return's in rekey protocol if error orccurred
2607 during the protocol. The execution must be terminated.
2608 Affected file silcd/protocol.c. Also, terminate the protocol
2609 always with timeout.
2611 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2613 * The client's Client ID was created initally from the wrong
2614 nickname (it could have been in format nick@host) in the
2615 silc_server_new_client. Affected file silcd/packet_receive.c
2617 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2619 * Added some SILC_LOG_ERROR's to various error conditions
2620 if client could not be added to ID cache. Affected files
2621 silcd/packet_receive.c and silcd/server.c.
2623 * When client's sock->user_data is freed, NULL also the
2624 client->router and client->connection pointers. Added check
2625 for these pointers being NULL to various places around the
2626 code. Affected file silcd/server.c.
2628 * Added client->data.registered == TRUE checks to various
2629 places around the code to assure that unregistered client's
2630 are not handled when it is not allowed. Affected file
2633 * Added `bool registered' fields to all
2634 silc_idlist_[server|client]_get_* routines to indicate whether
2635 the fetched client needs to be registered or not. Affected
2636 file silcd/idlist.[ch].
2638 * Add your own entry as registered to the ID cache in the
2639 server. Affected file server.c.
2641 * Fixed a bug in silc_server_new_server. The SilcServer was
2642 set as the new server's context instead of SilcServerEntry.
2643 This naturally caused some weird bugs.
2645 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2647 * Do not delete the channel rekey task when adding it
2648 for in silc_server_create_channel_key.
2650 * Changed the silc_server_create_channel_key to return
2651 TRUE or FALSE to indicate the success of the channel key
2654 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * Fixed MSVC++ project files and added missing files to
2657 Makefiles under win32/.
2659 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Do not add TCP_NODELAY flag if the operating system
2662 does not have it defined. Affected files are
2663 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2665 * Fixed buffer overflow from Irssi SILC Client. Affected
2666 file irssi/src/fe-common/core/themes.c.
2668 * Fixed double free in client library in the file
2669 lib/silcclient/client.c when disconnecting from server.
2671 * Applied double free patch from cras to Irssi SILC client.
2672 Affected files irssi/src/core/[modules/expandos].c
2674 * Fixed the disconnection handling to Irssi SILC Client.
2675 The application must call silc_client_close_connection
2676 in ops->connect client operation in case of failure of
2677 the connection. Affected file is
2678 irssi/src/silc/core/client_ops.c.
2680 * Do not set sock->protocol to NULL in the function
2681 silc_client_close_connection after executing the protocol's
2682 final callback since the sock might not be valid anymore.
2683 Affected file lib/silcclient/client.c.
2685 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2687 * Do not enable SILC_THREADS if the linking with libpthread
2688 did not happen. Affected file configure.in.pre.
2690 * Added notion to protocol specification that server must
2691 verify the sent authentication payload with CMODE when
2692 setting the channel founder key. Implemented it to the
2693 server. Affected file silcd/command.c.
2695 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2697 * Added _EXTRA_DIST SILC distribution variable to the
2698 distributions file. It is used to conditionally add extra
2699 files or directories to the specific distribution. Affected

2705 * Added README.WIN32 for instructions to compile the Toolkit
2708 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2710 * Fixed a double free in disconnection in the server. Affected
2711 file is silcd/server.c.
2713 * Fixed the lib/silcske/groups.c to work now also with GMP
2714 MP library. The string conversion did not work when using
2715 specific base and the base is indicated in the string as well.
2717 * Created win32/ directory which now includes MSVC++ specific
2718 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2719 It will appear only in the toolkit distribution
2721 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2723 * Changed the key material distribution function in case when
2724 the hash output is too short. The data is now concatenated
2725 a bit differently than it used to. Made the change to the
2726 SKE protocol specification.
2728 * Added better GMP detection to configure.in.pre. A patch
2731 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2733 * Fixed a minor bug in SKE that might cause some problem on
2734 some platforms. Affected file lib/silcske/silcske.c.
2736 * Added the cookie checking for initiator in the SKE. It checks
2737 that the responder returns the sent cookie unmodified. The
2738 affected file is lib/silcske/silcske.c. Added new SKE
2739 error type INVALID_COOKIE that can be sent during the
2740 negotiation. Fixed some memory leaks as well.
2742 * Added the "invalid cookie" error message to Irssi SILC client's
2745 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2747 * Added `task_max' field to the SilcClientParams to indicate
2748 the maximum tasks the scheduler can handle. If set to zero,
2749 default values are used. Affected file lib/silcclient/silcapi.h.
2751 * Fixed memory leaks in silc_client_close_connection. Affected
2752 file lib/silcclient/client.c.
2754 * Added silc_client_del_client_entry to client library to free
2755 all memory of given client entry. Affected file is
2756 lib/silcclient/idlist.[ch].
2758 * Added new functions silc_client_del_channel and
2759 silc_client_del_server to delete channel and server entries.
2760 Affected file lib/silcclient/[silcapi.h/idlist.c].
2762 * Removed silc_client_del_client_by_id from silcapi.h.
2764 * Fixed the INFO command to return the server's own info
2765 correctly when querying by Server ID. Affected file is
2768 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Removed the non-blocking settings in WIN32 code in the
2771 silc_sock_[read/write] and added SleepEx instead. Affected
2772 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2773 of input data is now checked with FIONREAD and ioctlsocket.
2775 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2777 * Call silc_schedule_task_del_by_context in the
2778 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2779 Affected file lib/silccore/silcprotocol.c.
2781 * Call silc_protocol_cancel for active protocols in the
2782 silc_server_close_connection if the funtion
2783 silc_server_free_sock_user_data has not been called.
2784 Affected file silcd/server.c.
2786 * Generic tasks cannot be deleted using the del_by_fd
2787 task deleting function since generic tasks does not match
2788 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2790 * Added a notion to SILCOPER help file that the SILCOPER works
2791 only on router server, not on normal server.
2793 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Added for WIN32 support for the new scheduler as well.
2796 Affected file lib/silcutil/win32/silcwin32schedule.c.
2798 * Fixed the SHA1 implementation to work on various platforms.
2800 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2802 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2803 API. It is part of the scheduler now. Everything else is
2804 as previously but some functions has changed their names.
2805 Checkout the lib/silcutil/silcschedule.h for the interface.
2806 Updated all applications to use the new interface. Affected
2807 files are lib/silcutil/silcschedule.[ch].
2809 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2811 * Found a bug in the SKE implementation. The HASH value,
2812 specified by the protocol, was not computed correctly. The
2813 public key of the responder was not added to the computation
2814 even though it is mandatory. Affected file lib/silcske/silcske.c.
2815 This unfortunately causes incompatibilities with older
2816 clients and servers.
2818 * Added WIN32 specific network init and uninit functions:
2819 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2820 the Winsock2. Affected file lib/silcutil/silcnet.h and
2821 lib/silcutil/win32/silcwin32net.c.
2823 * Set the socket always to nonblocking mode on WIN32 after
2824 reading data or writing data. Affected file is
2825 lib/silcutil/win32/silcwin32sockconn.c.
2827 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Fixed various compilation problems under WIN32. Affected
2830 files lib/silcutil/win32/silcwin32thread.c and
2831 lib/silcutil/win32/silcwin32schedule.c.
2833 * Removed all _internal.h #includes from public header
2834 files. Internal headers must never be included from
2837 Removed also the lib/silcske/payload_internal.h file.
2839 * All include files that may be needed (public and some others
2840 included by the public headers) by application developers are
2841 now copied to the ./includes directory. It does not copy any
2842 internal headers. Affected file Makefile.defines.pre and all
2843 Makefile.am's under lib/ and subdirs.
2845 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Do not change the ~/.silc directory's permissions automatically.
2848 Affected file irssi/src/silc/core/clientutil.c.
2850 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2852 * Do not cancel the protocol in silc_server_close_connection
2853 it might cause recursion. Now cancelled in the function
2854 silc_server_free_sock_user_data. Affected file silcd/server.c.
2856 * Fixed the silc_server_remove_clients_by_server to regenerate
2857 the channel keys correctly finally. Added also new function
2858 silc_server_remove_clients_channels to actually do it.
2859 Affected file silcd/server.c.
2861 * Fixed the silc_server_new_channel to not crash by giving
2862 wrong router to the new channel. Affected file is
2863 silcd/packet_receive.c.
2865 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2867 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2868 which is given as argument to the silc_client_alloc now.
2869 It can be used to configure the client and set various parameters
2870 that affect the function of the client.
2872 * The USERS command in server did not check whether the channel
2873 is private or secret. Affected file silcd/command.c.
2875 * Added new argument to the USERS command in protocol specification.
2876 The USERS command now can take the channel name as argument
2877 as well. Added support for this in client and server and
2878 updated the protocol specs.
2880 * Completed the GETKEY command in client. It can be now used
2881 to fetch also servers public key not only some clients.
2882 Affected files lib/silcclient/command[_reply].c.
2884 * Added silc_client_get_server to return server entry by the
2885 server name. Affected files lib/silcclient/silcapi.h and
2888 * Redefined the IDENTIFY command in protocol specification to be
2889 more generic. It now can be used to query information about
2890 any entity in the SILC Network, including clients, servers and
2891 channels. The query may be based either the entity's name
2892 or the ID. Added support for this in both client and server.
2894 Affected files silcd/command.c and lib/silcclient/command.c
2895 and command_reply.c.
2897 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2898 the _from_client and _from_server functions. Affected file
2901 * Added silc_client_get_channel_by_id_resolve to the file
2902 lib/silcclient/silcapi.h to resolve channel information by
2903 its ID. Added also silc_client_get_channel_by_id that
2904 does not resolve it from the server.
2906 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Added SilcServerEntry context into the client library
2909 to represent one server. The INFO command now allocates
2910 these to save the resolved server info. For now on the
2911 client library will also keep information about servers,
2912 connected and resolved with INFO.
2914 The INFO command now allocates the SilcServerEntry context
2915 and saves the server info there. The COMMAND_REPLY in
2916 the INFO now returns the parameters to application in
2917 same order as defined in the protocol specification.
2919 The entries are cached in the client->server_cache.
2921 * The INFO command is now issued after received the Client ID
2922 from the server. Affected file lib/silcclient/client.c.
2924 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2925 to the application as the mode changer might be server.
2926 It is guaranteed that NULL is not returned anymore to the
2927 application. Affected file lib/silcclient/client_notify.c.
2929 The ID Type is now also passed to the application so that
2930 it can check whether the returned entry is SilcClientEntry
2933 Added new function silc_client_get_server_by_id to return
2934 the server entry by ID. Affected files are the
2935 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2937 * Do not create the channel in the Irssi SILC Client when issuing
2938 the JOIN command but when received the sucessful JOIN command
2939 reply. Otherwise the channel might get created even though we
2940 could not join it. The Affected file is
2941 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2943 * Fixed a channel joining bug in router. The router must also
2944 check the channel modes, invite and ban lists etc. when serving
2945 the JOIN command sent by normal server. Affected file is
2946 silcd/command.c. The router now resolves the client's
2947 information from the server who sent the JOIN command if it
2948 does not know it, and processes the JOIN command only after
2951 * Changed the SilcCommandCb to take new argument; void *context2.
2952 Affected file lib/silccore/silccommand.h
2954 The second argument in the command callbacks in the server now
2955 includes the SilcServerCommandReplyContext if the command was
2956 called as pending command callback from the command reply.
2957 Otherwise it is NULL. When called as pending the status of the
2958 command reply will be checked and if it was erronous the
2959 error will be sent to the original sender of the command.
2960 This way the client always receives the error messages even
2961 though the server was actually the one who received the error
2962 when it resent the command to router, for example. Affected
2963 files silcd/command[_reply].[ch].
2965 * Fixed sending WHOWAS command's error message to client if
2966 the requested client could not be found. It was missing.
2969 * Changed the CMODE and CUMODE commands reply arguments in the
2970 protocol specification. The Channel ID is now sent in both
2971 of the commands to identify the channel. Implemented this
2972 new feature to the client and server. Affected files
2973 lib/silcclient/command_reply.c and silcd/command.c.
2975 * Made better checks for invite and ban lists in the JOIN
2976 command in server. Affected file silcd/command.c.
2978 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * The server now performs the incoming host IP/DNS lookup
2981 using the silc_socket_host_lookup and thus does not block
2982 the server anymore. Affected file silcd/server.c.
2984 * Completed the multi-thread support for SILC Scheduler in
2985 the lib/silcutil/silcschedule.c.
2987 * Fixed the configure.in.pre to detect the pthread correctly
2990 * Fixed a deadlock in silc_task_queue_wakeup in the file
2991 lib/silcutil/silctask.c.
2993 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Added new function silc_schedule_wakeup that is used in
2996 multi-threaded environment to wakeup the main thread's
2997 schduler. It needs to be used when a thread adds a new task
2998 or removes a task from task queues. After waking up, the
2999 scheduler will detect the task queue changes. If threads
3000 support is not compiled in this function has no effect.
3001 Implemented the wakeup mechanism to both Unix and WIN32
3002 systems. Affected files are lib/silcutil/silcschedule.[ch],
3003 lib/silcutil/unix/silcunixschedule.c and the
3004 lib/silcutil/win32/silcwin32schedule.c.
3006 * Added new function silc_task_queue_wakeup to wakeup the
3007 scheduler by the specified task queue. Affected file
3008 lib/silcutil/silctask.[ch].
3010 * The silc_socket_host_lookup_start now wakes up the scheduler
3011 after adding the timeout task. Affected file is
3012 lib/silcutil/silcsockconn.c.
3014 * The silc_socket_host_lookup is synchronous now if the threads
3015 support is not compiled in. However, the callback is still
3016 called asyncronously through the scheduler, anyway. Affected
3017 file lib/silcutil/silcsockconn.c.
3019 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3021 * Added new function silc_socket_host_lookup to perform
3022 asynchronous IP and FQDN lookups for the socket connection.
3023 Affected files lib/silcutil/silcsockconn.[ch].
3025 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3028 that may or may not compile the mutex support in.
3030 Changed the silc_mutex_alloc interface. It allocates the
3031 mutex now to the sent pointer and returns TRUE or FALSE.
3033 Affected file lib/silcutil/silcmutex.h.
3035 * Wrote the SILC Task Queue interface to support multi-threads.
3036 Affected file lib/silcutil/silctask.[ch].
3038 * Wrote the SILC Scheduler to support multi-threads. Affected
3039 file lib/silcutil/silcschedule.c.
3041 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3043 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3044 in lib/silcutil/win32/.
3046 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Defined SILC Mutex API and SILC Thread API and implemented
3049 them for Unix. Affected files are
3050 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3051 lib/silcutil/unix/silcunixmutex.c and
3052 lib/silcutil/unix/silcunixthread.c.
3054 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3056 * Fixed the silc_server_remove_clients_by_server's channel
3057 key re-generation. The hash table handling was incorrect
3058 and would not work with many channels. Affected file is
3061 * Fixed some memory leaks around the server code.
3063 * Rewrote the silc_server_get_users_on_channel to support IPv6
3064 based Client ID's. Affected file silcd/server.c.
3066 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3067 specification. However, a separate document must be written
3068 to define the detailed signing procedure and the payload
3069 associated with the flag. Defined the flag to the
3070 lib/silccore/silcchannel.h as well.
3072 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3074 * Changed the dynamic tables to static size tables in the
3075 lib/silccrypt/silchmac.c.
3077 * Removed GCC dependencies from the code. A patch by cras.
3079 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3081 * Do not show the error "Error receiving packet bla bla"
3082 in server if it really was not an error (-2 means that reading
3083 is pending). Affected file silcd/server.c.
3085 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3087 * Fixed a possible crash in silc_server_remove_clients_by_server
3088 in silcd/server.c. Fixed there also some memory leaks.
3090 * Fixed the silc_idlist_replace_client_id. It could replace
3091 wrong key in the hash table. Affected file silcd/idlist.c.
3093 * Do not check whether there are global users on the channel
3094 if the channel->global_users is FALSE. Affected functions
3095 silc_server_remove_from_one_channel and
3096 silc_server_remove_from_channels in silcd/server.c. Also,
3097 do not check if the removed client is local as we can be
3098 sure that global client was not removed from the channel
3099 and checking for global users is not needed.
3101 * The silc_server_remove_clients_by_server now re-generates
3102 the channel keys correctly for those channels that had
3103 clients removed from them. Affected file silcd/server.c.
3105 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Found the reason of random crashes in the server. We weren't
3108 ignoring the SIGPIPE signal (which can be sent in write())
3109 and it crashed the server. Affected file silcd/silcd.c.
3111 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * Assure that sock->user_data is not NULL in the function
3114 silc_server_packet_send in silcd/packet_send.c.
3116 * Disconnect the remote connection if it could not be added
3117 to any ID lists in the server. The affected file is
3120 * Check in silc_server_packet_send[_real/dest] that the
3121 socket is not disconnecting and ignore the data if it is.
3122 Affected file silcd/packet_send.c.
3124 * Define inline to __inline on native WIN32 compilation.
3125 Affected file includes/silcwin32.h.
3127 * Added some explicit type casts for inline code since MSVC
3128 require them. Affected files lib/silcutil/silcbuffer.h,
3129 lib/trq/silcdlist.h and lib/trq/silclist.h.
3131 * Print warning in log files from now on if the packet
3132 decryption fails. Affected file silcd/server.c.
3134 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3136 * Changed the `say' client operation's interface to accept
3137 new `type' argument to indicate the type of the message sent
3138 by the library. The application may filter the library's
3139 messages according the type. The affected file is the
3140 lib/silcclient/silcapi.h.
3142 * Added two new functions to lib/silcclient/silcapi.h:
3143 silc_client_del_client and silc_client_del_client_by_id.
3144 Affected file lib/silcclient/idlist.c.
3146 * Moved the clientincludes.h from includes/ to silc/ and
3147 serverincludes.h from includes/ to silcd/.
3149 * The modes for the CMODE and CUMODE are now passed as
3150 uint32 for application with COMMAND_REPLY. The affected
3151 file is lib/silcclient/command_reply.c.
3153 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * /WHOIS without arguments shows client's own information.
3156 Affected file lib/silcclient/command.c.
3158 * Changed PING to not accept any arguments. The specs
3159 says that client can ping only the connected server so
3160 requiring an argument is not needed. Affected file is
3161 lib/silcclient/command.c.
3163 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3165 * Fixed a fatal bug in private message sending and reception
3166 encryption and decryption when using private message keys.
3167 The implementation was incorrect and did not follow the
3168 specification. It causd that some of the message were
3169 lost since it did not use the sending and receiving keys
3170 as the protocol suggests. This has been fixed and will cause
3171 incompatibilities with older clients when sending private
3172 message encrypted with private message keys. Affected files
3173 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3174 and various other in Irssi SILC Client.
3176 Added `responder' boolean argument to the functions
3177 silc_client_add_private_message_key[_ske] to indicate when
3178 the key is added as responder or initiator of the key
3181 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3183 * Removed the silc_ske_check_version function and created
3184 a SilcSKECheckVersion callback. Added also a function
3185 silc_ske_set_callbacks that is now used to set all SKE
3186 callbacks. The callback functions are not given to
3187 the SKE functions anymore, but this function is used to
3190 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3192 * Added `silc_version' argument to the silc_client_alloc
3193 to define the version of the application for the library.
3194 The library will use the version string to compare it
3195 against the remote host's (usually a server) version
3196 string. Affected file lib/silcclient/silcapi.h
3198 * Added the KE protocol context to Key Agreement context
3199 in client library so that we can abort the SKE if it
3200 is in process when we get timeout. Affected file is
3201 lib/silcclient/client_keyagr.c.
3203 * Do not resolve the client ID forever if it returns in the
3204 first time that such client does not exist. This was done
3205 for example with private message. Affected file is
3206 lib/silcclient/client_prvmsg.c.
3208 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3210 * Do not add regex.h for WIN32. The affected file
3211 includes/silcincludes.h.
3213 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3214 not work yet 100%. It generates the DLL's automatically
3215 when compiling with --with-win32 under cygwin.
3217 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3219 * lib/contrib/regex.c is not compiled on WIN32.
3221 * Added silc_net_get_socket_opt function to the
3222 lib/silcutil/silcnet.h.
3224 * Added includes/silcwin32.h for WIN32 specific includes
3227 * Do not use ptime structure or any of the posix process
3228 functions on WIN32 in lib/silccrypt/silrng.c.
3230 * Added silc_gettimeofday to provide generic function
3231 for struct timeval on all platforms. Added the function
3232 to lib/silcutil/silcutil.h.
3234 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3236 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3237 library as they clearly belong there. As a plus side we
3238 can make the actual socket connection routines platform
3241 Added also new generic function silc_socket_read and
3242 silc_socket_write (that used to be silc_packet_[read/write].
3243 The implementation of these are platform specific.
3245 * Added WIN32 specific routines of silc_socket_[read/write]
3246 to lib/silcutil/win32/silcwin32sockconn.c.
3248 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3250 * Added preliminary support for native WIN32 compilation under
3251 cygwin (using the -mno-cygwin option for GCC) to the
3252 ./configure.in.pre. The --with-win32 now prepares the
3253 compilation for native WIN32.
3255 * Rewrote the SILC Scheduler interface in the file
3256 lib/silcutil/silcschedule.h. The scheduler is now context
3257 based and does not have anymore any global static scheduler.
3258 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3259 and created lib/silcutil/win32 directory for WIN32 based
3262 * Added Unix specific network routines to the
3263 lib/silcutil/unix/silcunixnet.c and the old
3264 lib/silcutil/silcnet.c includes now only generic routines.
3266 Added WIN32 specific network routines to the
3267 lib/silcutil/win32/silcwin32net.c.
3269 * Added Unix specific utility functions from the
3270 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3272 * Added WIN32 SILC Scheduler to the file
3273 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3276 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3278 * Do not handle JOIN notify in the server if the target client
3279 is not registered (idata->registered == FALSE). The affected
3280 file is silcd/packet_receive.c.
3282 * Update the nickrec->founder in event_cumode in the Irssi SILC
3283 client. Affected file irssi/src/silc/core/silc-channels.c.
3285 * Fixed the CUMODE_CHANGE notify handling in the server when
3286 server and router are announcing their clients on channels.
3287 Now the mode changes are saved and notified correctly. The
3288 affected file is /silcd/packet_receive.c.
3290 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3291 They really did not replace the cache entry in the ID Cache.
3292 Now they do that. Affected file silcd/idlist.c.
3294 * Fixed the KICK notify handling in the Irssi SILC client to
3295 update the channel records so that the kicked client does not
3296 appear to be on the channel. The affected file is
3297 irssi/src/silc/core/silc-channels.c.
3299 * Always update the conn->current_channel when executing command
3300 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3302 * Fixed the KILL notify handling in Irssi SILC client to remove
3303 the killed client on all channels.
3305 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Fixed the silc_parse_command_line to remove extra spaces
3308 from the start and end of the arguments. Affected file is
3309 lib/silcutil/silcutil.c.
3311 * Cancel and free any active protocol in the function
3312 silc_server_close_connection. Affected file silcd/server.c.
3314 * Cancel and free any active protocol in the function
3315 silc_client_close_connction. Affected file is
3316 lib/silcclient/client.c.
3318 * Do not execute the KILL command for clients that are in
3319 history (ie. they are not in the network). Affected file is
3322 * Fixed KILL notify handling, client does not crash anymore.
3323 Affected file irssi/src/silc/core/silc-channels.c.
3325 * Reduced the default packet buffer size from 2048 to 1024 in
3326 lib/silccore/silcpacket.c.
3328 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3329 counter to the SKE context that is incresed when the SKE library
3330 performs async operation outside the library. If the outside
3331 process frees the SKE context and FREED status will be set
3332 and the library will detect after the sync operation that the
3333 libary is freed. The affected files are
3334 lib/silcske/silcske[_status].[ch].
3336 * Resolve the client entry information in the function
3337 silc_client_channel_message to assure that NULL pointer is not
3338 passed as client entry to the application. */
3340 * Fixed the task timeout calculation to assure that there is
3341 never negative timeouts. The affected file is
3342 lib/silcutil/silcschedule.c.
3344 * Fixed the channel user mode notification sending in server.
3345 It was sent point-to-point to the router (or to server by router)
3346 but it needs to be destined to a channel. The routines now
3347 supports sending the channel user mode notifys to the channels
3348 when announcing clients and channels. Affected files are
3349 silcd/server.c and silcd/packet_receive.c.
3351 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3352 It did not actually replace the old channel entry in the cache.
3353 Affected file lib/silcclient/client_notify.c.
3355 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Fixed a possible crash in silc_packet_send_prepare. It now
3358 assures always that there is enough space in the buffer and
3359 at the tail area of the buffer (for MAC).
3361 Fixed the inbound buffer reallocation in silc_packet_read.
3362 It was old code and did not handle the reallocation correctly.
3365 The affected file is lib/silccore/silcpacket.c.
3367 * Fixed buffer overflow in silc_parse_nickname in the file
3368 lib/silcutil/silcutil.c.
3370 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * make install generates new server keys only if there is not
3375 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3377 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3378 Added check that if the NOREPLY is set then we will not send
3379 the away message. This avoids infinite loop of away messages
3380 if both clients are away. The affected file is
3381 lib/silcclient/client_prvmsg.c.
3383 * Fixed client crash if /NICK was given without arguments.
3384 Affected file lib/silcclient/command.c.
3386 * Server does not send the invite list in INVITE command back
3387 to the client if the list was not altered. Added this notion
3388 to the protocol spec as well. Affected file silcd/command.c.
3390 Fixed possible crash in INVITE command by checking the
3391 value of silc_server_get_client_route command.
3393 * Fixed the INVITE notify type handling. The arguments are now
3394 taken in correct order and client does not crash. The affected
3395 file is irssi/src/silc/core/silc-channels.c.
3397 Removed the "Inviting xxx to channel" message from the
3398 client library away and let the application handle it.
3399 Affected file lib/silcclient/command.c. Added that message
3400 to Irssi SILC client's message formats.
3402 * Fixed CMODE command crash in client. It now checks the
3403 amount of arguments correctly and does not crash. The affected
3404 file is lib/silcclient/command.c.
3406 * Do not create new channel automatically in silc_channels_join
3407 but check whether the channel by that name already exists.
3408 Affected file irssi/silc/core/silc-channels.c.
3410 * Do not send the SERVER_SIGNOFF to router if the disconnected
3411 entity was the router. Affected file silcd/server.c.
3413 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3414 SILC client as it was missing from there.
3416 Added the handling of the KICK notify to the Irssi SILC client
3417 as it was missing. Added "you have been kicked" message to
3418 Irssi SILC client's message modules formats.
3420 Added the handing of the KILL notify to the Irssi SILC client
3421 as it was missing. Added the kill message module formats
3424 The affected file is irssi/src/silc/core/silc-channels.c.
3426 * The router did not save the channel mode the server announced.
3427 Affected file silcd/packet_receive.c.
3429 * Fixed a possible crash in INFO command in server. If the
3430 server did not provide the server info it crashed. Affected
3431 file silcd/command.c.
3433 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * Fixed the GETKEY command in the server to check also the
3436 global list. Otherwise the GETKEY would not work correctly
3437 in normal SILC server. Affected file silcd/command.c.
3439 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3441 * Fixed GETKEY crash, it crashed if the command did not succseed.
3443 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3445 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3446 is now real and not just an macro interface to GMP.
3448 Removed the entire GMP from the source tree and imported new
3449 NSS MPI library instead. Reason for removing GMP is that it is
3450 extremely large and compiles extremely slow. The NSS MPI
3451 is only a few files and compiles in less than 10 seconds.
3452 The speed is also about the same as GMP. The MPI is imported
3453 to lib/silcmath/mpi.
3455 If the system has GMP installed we will still use the GMP.
3456 If it is not then the NSS MPI will be compiled.
3458 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Merged a long nickname (127 characters long) crash bugfix from
3461 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3463 * Merged a freed memory reference bugfix from Irssi CVS tree.
3464 Affected file irssi/src/core/commands.c.
3466 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3468 * Added the server's public key sving and verification to the
3469 server when performing the SKE. This was missing and the
3470 remote server's (or router's) public key was accepted without
3471 checking whether we have it previously or trust it at all.
3472 Affected file silcd/protocol.c.
3474 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Check in the silc_server_timeout_remote if protocol is active
3477 and make sure that the protocol's final callback is called so
3478 that all memory if freed. Affected file silcd/server.c.
3480 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * silc_server_whois_send_reply crashed the server if the nickname
3483 was 127 characters long. Affected file silcd/command.c.
3485 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3487 * Added sanity check to the silc_server_new_client. If the hostname
3488 is provided inside username then check that the provided hostname
3489 really is the same as the resolved one. If the hostname was not
3490 resolved then check it from the public key. Affected file is
3491 silcd/packet_receive.c.
3493 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3494 if the server disconnected us and the connection is not valid
3495 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3497 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3498 the library to the lib/silcutil/silcutil.[ch].
3500 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Close log file after open. Affected file
3503 lib/silcutil/silclog.c.
3505 * Check whether sock == NULL in silc_client_send_packet and return
3506 if it is. Affected file lib/silcclient/silcclient.c.
3508 * Check rec->entry == NULL in the Irssi SILC Client before
3509 sending the channel message. Affecte file is
3510 irssi/src/silc/core/silc-servers.c.
3512 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Merged a splitted window bugfix from Irssi CVS tree. The
3515 affected file is irssi/src/fe-text/textbuffer-view.c.
3517 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3518 It did not print nickname.
3520 * Improved the distributions system a bit.
3522 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3525 irssi/src/fe-text/gui-window.c.
3527 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3528 to in-active server. The affected file is
3529 irssi/src/silc/core/client_ops.c.
3531 * Resolve the client in USERS command reply if the entry does
3532 not have username resolved. The affected file is
3533 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3534 command to WHOIS command to really resolve stuff. The USERS
3535 is not used any more in any critical section so WHOIS can
3536 be used even though it might be slower than IDENTIFY.
3538 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3541 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Changed the protocol API a bit more consistent in the
3544 lib/silccore/silcprotocol.[ch].
3546 * Changed the following headers to ROBODoc format:
3548 lib/silccore/silcpayload.h
3549 lib/silccore/silcprotocol.h
3550 lib/silccore/silcsockconn.h
3552 All core library headers are now formatted.
3554 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Fixed a bug in Irssi SILC client; do not show that you are
3557 server/router operator if you really are not. Affected file is
3558 irssi/src/silc/core/client_ops.c.
3560 * Renamed silc_command_free_payload to silc_command_payload_free.
3561 Affected file lib/silccore/silccommand.h
3563 * Added silcmath.h to include the prototoypes of various routines
3564 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3567 * Changed the following headers to ROBODoc format:
3569 lib/silccore/silcchannel.h
3570 lib/silccore/silccommand.h
3571 lib/silccore/silcid.h
3572 lib/silccore/silcidcache.h
3573 lib/silccore/silcmode.h
3574 lib/silccore/silcnotify.h
3575 lib/silccore/silcpacket.h
3576 lib/silcmath/silcmath.h
3578 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Added checking to the server code not to start the server if
3581 ciphers and stuff are not configured properly. Affected files
3582 silcd/serverconfig.[h] and silcd/server.c.
3584 * Changed the layout of the header files of the public interfaces
3585 in the SILC libraries. The new layout supports ROBODoc
3586 documentation tool (and some others) so that it is easy to create
3587 a library reference manual. All the other headers and source
3588 code must still follow the CodingStyle document. Also source
3589 code must not include these ROBODoc stuffs, only the headers.
3590 Furthermore, all public interface headers must now be named
3591 by using `silc' prefix, example: silcapi.h, silccipher.h.
3592 Some files were renamed due to this. All the other headers
3593 must not be used as public interfaces. I will update the
3594 CodingStyle document later. Changed following headers, so far:
3596 lib/silcclient/silcapi.h
3597 lib/silccore/silcauth.h
3598 lib/silccore/silcprivate.h
3599 lib/silccrypt/silcdh.h
3601 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Removed silc_client_packet_send_flush from the client library
3606 as it is not needed. Affected file lib/silcclient/client.[ch].
3608 * Added printing of message of unresolved authentication method
3609 to the Irssi SILC client. Added it to the module formats.
3610 Removed the same message from the client library.
3612 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Added new distribution feature, DISTLABEL. Every distribution
3615 can define own preprocessor label that can be used in the
3616 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3617 file distributions, acconfig.h.pre and prepare.
3619 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Added Makefile.defines_int to include the actual definitions
3622 for Makefile.defines.in. Tested the new distribution system,
3623 created distributions and tested installation.
3625 * Added AWAY message printing to the Irssi SILC client. Added
3626 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3628 * Added SCONNECT command to call the SILC's CONNECT command.
3629 Cannot use CONNECT directly since Irssi uses that internally.
3630 Affected file irssi/src/silc/core/silc-servers.c.
3632 Added ACTION local command. It is same as ME command but takes
3633 the channel as mandatory argument.
3635 Rewrote some of the Irssi's help files to suite for SILC
3638 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Added Makefile.defines[.in] that should for now on be included
3641 in all Makefile.am file in the source tree. That file includes
3642 all common compilation definitions for SILC source tree.
3644 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Minor changes to the ./prepare script to change the package
3647 name according the distribution name to the configure.in.
3649 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3651 * Created new distribution system. Added file `distributions'
3652 that defines all the distributions that can be created out of
3653 the SILC source tree. The ./prepare script now reads that
3654 file to determine how to prepare the distributions. The
3655 first argument to the ./prepare is the name of the distribution
3656 and second is the version of the distribution. If given
3657 without arguments it creates the default (toolkit) distribution
3658 with the default version (defined in ./prepare).
3660 All Makefile.am files that are subject to the distributions
3661 are now named as Makefile.am.pre. These are ./Makefile.am
3662 and lib/Makefile.am. Others may be changed later.
3664 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * Added invite list, ban list, some key management and connection
3667 error message printing to module formats in the Irssi SILC client.
3669 * Added new silc_client_set_away_message to set the away message
3670 that is back to the person who sent private message. The
3671 affected file lib/silcclient/silcapi.h and the
3672 lib/silcclient/client_prvmsg.c.
3674 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Fixed the private message sending in the Irssi SILC client,
3677 added local command KEY to the Irssi SILC client.
3679 Added key management and key agreement message formats to the
3680 irssi/src/fe-common/silc/module-formats.[ch].
3682 Added USERS (alias WHO) printing, server/router operator
3683 indication and LIST command printing to the module formats.
3685 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3687 * Fixed channel joining notify handling, cumode notify handling
3688 from Irssi SILC client.
3690 * Added SILC specific module-formats to the Irssi SILC client so
3691 that SILC specific message hilighting, colors etc is possible.
3692 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3694 Added channel mode, channel user mode, actions, notices,
3695 whois and whowas printing to the the module-formats.c.
3697 * Fixed a bug in channel deletion in the server. The channel
3698 is not left to the cache even if the channel founder auth mode
3699 is set when there are no users anymore on the channel. Affected
3700 file silcd/server.c.
3702 * The silc_net_localhost now resolves the entire hostname including
3703 the domain name. Affected file lib/silcutil/silcnet.c.
3705 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3707 * Changed the ask_passphrase client operation to be ascynchronous.
3708 It has now a completion callback and a context that the
3709 application must call after it has got the passphrase from
3710 the user. Affected files lib/silcclient/silcapi.h,
3711 lib/silcclient/protocol.c, lib/silcclient/command.c and
3714 Added SilcAskPassphrase callback that the application calls
3715 to deliver the passphrase to the library.
3717 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3718 The public key verification and especially a certificate
3719 verification is asynchronous procedure.
3721 Added new SILC_SKE_STATUS_PENDING status to indicate the
3722 request is pending and a callback will be called to finalize
3725 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3726 indicate that remote end did not send its public key (or
3727 certificate), even though we require it. Added check for this
3728 condition in the SKE. This was a security bug, now fixed.
3730 Defined new SilcSKEVerifyCbCompletion callback that is called
3731 when the verification process is completed.
3733 The affected files lib/silcske/silcske_status.h and
3734 lib/silcske/silcske.[ch].
3736 * Changed the verify_public_key client operation to be async
3737 as well. Defined SilcVerifyPublicKey callback that is used to
3738 indicate the success of the public key verification process.
3740 Changed the server and client to use the new async client
3743 * Changed the Irssi SILC client's internal scheduler to be called
3744 twice as many times as it used to be. As a result the client
3745 should be a bit faster now. Affected file is
3746 irssi/src/silc/core/silc-core.c.
3748 * Added support to Irssi SILC client of asynchronous public key
3749 verification and passphrase inquiry. Affected file is
3750 irssi/src/silc/core/silc-core.c.
3752 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Do not say "You have left channel %s" in client library.
3755 Moved it to the application. Affected files are
3756 lib/silcclient/command.c and silc/client_ops.c.
3758 * Fixed silc_client_get_clients. Command context was not
3759 duplicated and was freed memory in the callback. Affected
3760 file lib/silcclient/idlist.c.
3762 * Do not say "you are now talking..." on JOIN command in the
3763 client library. The appliation must handle it.
3765 * Do not say ".. changed topic to" in command reply in the
3766 client libary. The application must handle it.
3768 * Fixed TOPIC command sending in the client library.
3770 * Fixed a memory leak in silc_client_command_free in the file
3771 lib/silcclient/command.c.
3773 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Imported a modified version of Irssi client to the source tree.
3776 The Irssi will be used to create a new client called
3777 Irssi SILC. Imported to irssi/.
3779 Added silc_core_init_finish function to the Irssi. Affected
3780 file irssi/configure.in.
3782 A lot changes in the Makefile.ams around the irssi tree.
3784 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3786 * Do not rehash if the new size is same as the old size of the
3787 hash table, in the silc_hash_table_rehash*. The affected file
3788 lib/silcutil/silchashtable.c.
3790 * Replaced hash_table_del_by_context calls from the server
3791 (when channel->user_list and client->channels) to the
3792 hash_table_del as it is sufficient and faster.
3794 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * Added silc_hash_table_list, silc_hash_table_get and the
3797 SilcHashTableList structure to provide an alternative way to
3798 traverse the hash table. The affected files are
3799 lib/silcutil/silchashtable.[ch].
3801 * Changed the server's idlist routines to use the hash table
3802 routines to optimize the code.
3804 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3806 * Replaced the client entry's `channel' list and channel entry's
3807 `user_list' list to hash tables for optimized lookup. Changed
3808 the code to use the hash table interface around the code.
3809 Affected file lib/silcd/idlist.[ch].
3811 * Added `auto_rehash' boolean argument to the function
3812 silc_hash_table_alloc to indicate whether the hash table should
3813 auto-rehash when it thinks is appropriate time. It will
3814 increase the hash table size if the there is twice as much
3815 entries in the table than the size of the table, and will
3816 decrease the size if there are twice as less entries than
3817 the size of the table.
3819 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3823 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * silc_idcache_purge_by_context deletes the entry now by context
3826 as it is supposed to do. Affected file lib/silccore/idcache.c.
3828 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3829 client is not anymore valid (WHOWAS givens the info) and not
3830 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3832 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3834 * Removed the `data' and `data_len' arguments from the ID Cache
3835 interfaces and added `name' argument. ID Cache does not handle
3836 anymore the binary data only a names associated with given ID.
3838 * When hashing a Client ID with silc_hash_id the entire ID is
3839 not hashed anymore, instead only the hash of the Client ID is
3840 hashed. This way we can access the Client ID from the cache
3841 with Client ID but with the hash of the ID (which is a hash of
3842 the nickname) as well without any difference in performance.
3844 Added also silc_idcache_find_by_id_one_ext to do one on one
3845 searching when we have the actual ID. Added also function
3846 silc_hash_client_id_compare. The affected files are
3847 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3849 * When hashing the name associated with a ID it is always done
3850 in lowercase. This way we can access the cache without worrying
3851 about case-sensitivity, even though, for example nicknames are
3854 * Fixed a bug in server with channel message sending. It put
3855 wrong ID type as destination ID. The affected file
3856 silcd/packet_send.c.
3858 * silc_idcache_del_by_context now deletes from all hash tables
3859 by context. Affected file lib/silccore/idcache.c.
3861 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3863 * Changed the client library to use the new ID Cache interface.
3864 Changes around the source tree.
3866 * Added silc_hash_table_rehash_ext to rehash with specific
3867 hash function. Affected file lib/silcutil/silchashtable.[ch].
3869 * Added silc_hash_string_compare to compare two strings in the
3870 hash table. Affected file lib/silcutil/silcutil.[ch].
3872 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Added new function silc_idcache_del_by_context into the
3875 lib/silccore/idcache.[ch].
3877 * Changed the server's ID list routines to use the new ID Cache
3878 interface. Changes around the source tree.
3880 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Added silc_hash_table_del[_by_context]_ext functions in to the
3883 lib/silcutil/silchashtable.[ch].
3885 Removed silc_hash_table_find_all* routines and added new
3886 silc_hash_table_find_foreach to replace them.
3888 Added silc_hash_table_replace_ext function as extended
3889 replacing function. Separated the simple hash table interface
3890 from the extended hash table interface in the file
3891 lib/silcutil/silchashtable.h.
3893 * Fixed minor bugs and changed it to use some of the new
3894 hash table functions in lib/silccore/idcache.c
3896 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Added new function silc_hash_table_find_all to return all keys
3899 in the hash table by the specified key. As the hash table is
3900 collision resistant it also makes it possible to have several
3901 duplicate keys in the hash table. This function may be used to
3902 find all of the keys from the hash.
3904 Added user_context arguments to the SilcHashFunction,
3905 SilcHashCompare and SilcHashDestructor to deliver user specified
3908 Added new fuctions silc_hash_table_find[_all]_ext to do
3909 extended lookup with specified hash and compare functions and
3910 specified user contexts.
3912 Added new function silc_hash_table_add_ext to add the key
3913 with specified hash function and user context.
3915 Added new function silc_hash_table_foreach to traverse all
3916 entrys in the hash table. Added SilcHashForeach callback
3919 Added new function silc_hash_table_del_by_context to delete
3920 the entry only if the context associated with the key matches.
3922 Affected files are lib/silcutil/silchashtable.[ch].
3924 * Removed silc_hash_[server/client/channel]_id and added just
3925 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3926 silc_hash_id_compare to compare two ID's using as the hash table
3927 comparison function. Added also silc_hash_data to hash
3928 binary data and silc_hash_data_compare to compare it.
3930 * Removed silc_idlist_find_client_by_hash as it is not needed
3931 anymore. Affected file silcd/idlist.[ch].
3933 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3934 to use internally the SilcHashTable. The new ID Cache is a lot
3935 faster than the old one. Some of the ID Cache interface was also
3936 rewritten and obsolete and stupid functions were removed.
3938 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Added entry_count field to the SilcHashTable to keep the number
3941 of the entries in the table. Implemented the function
3942 silc_hash_table_rehash. Added new function
3943 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3945 Fixed a minor bug in silc_hash_table_free.
3947 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3948 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3949 into the lib/silcutil/silcutil.[ch].
3951 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Implemented a collision resistant hash table into the
3954 lib/silcutil/silchashtable[ch]. See the header and the source
3955 for the SilcHashTable API.
3957 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3959 * Merged dotconf version 1.0.2 into lib/dotconf.
3961 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3963 * Do not compile anything in lib/silcsim/* if the SIM support
3964 is not enabled. The tree should now compile without problems
3967 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Compiled the SILC under cygwin. Compiled and tested briefly
3970 without problems. More tests needed. The SIMs didn't compile
3973 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3975 * Fixed possible crash in silc_get_username in the
3976 lib/silcutil/silcutil.c.
3978 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Fixed a va_arg in silc/client_ops.c.
3982 * Oops, RC5 routines were named AES and caused some problems
3983 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3985 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Added new SilcIDIP structure into the lib/silccore/id.h and
3988 replaced the old `ip' fields from all SILC ID's to that type.
3989 This is a step towards IPv6 support.
3991 The silc_id_get_len takes now the ID as an extra argument.
3992 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3993 both IPv4 and IPv6 based ID's.
3995 The affected files are lib/silccore/id.[ch] and other files
3996 around the tree using these routines.
3998 * Removed the ID length arguments in server from various
3999 silc_server_send_notify_* routines -> they are not needed
4002 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4004 * Fixed memory leak in silc_encode_pem_file in the file
4005 lib/silcutil/silcutil.c.
4007 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Check minor version as well in the SKE. Affected files are
4010 silcd/protocol.c and lib/silcclient/protocol.c.
4012 * Added --identifier option to the server so that an identifier
4013 can be when creating the public key for the server. Affected
4014 file is silcd/silcd.c.
4016 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4017 lib/silccrypt/silcpkcs.c.
4019 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Register default ciphers and stuff when using -C option with
4022 the server. Affected file sildc/silcd.c.
4024 * Put back the servers public key filename format, it is better
4025 than the new one. For now, the client keys are saved with the
4026 new filename format. The affected file silc/client_ops.c.
4028 * Implemented the Cipher API for the rest of the ciphers that
4029 did not implement it or implemented it the wrong way.
4031 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * Register default ciphers and stuff when using the -S option
4034 in the client. Affected file silc/silc.c. Same also when
4035 creating new key pair with -C option.
4037 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4039 * Fixed the silc_verify_public_key client operation function to
4040 save the public keys differently. The fingerprint is now
4041 used as filename and not the hostname. This way also the
4042 client keys are saved uniquely and not with hostnames. The
4043 affected file is silc/client_ops.c.
4045 * Trimmed the silc_hash_fingerprint function to remove extra
4046 whitespaces from the end of the fingerprint. The affected
4047 file is lib/silccrypt/silchash.c.
4051 * Added silc_cipher_register_default function to register all
4052 default ciphers. It can be used when configuration files
4053 does not exist and the application does not want any specific
4054 ciphers in any specific order.
4056 The SilcDList is now used as silc_cipher_list dynamically
4057 allocated cipher list. Removed the static list all together
4058 and now all ciphers must be allocated to the dynamic list.
4059 The silc_cipher_alloc routine was changed to check only the
4062 All silc_cipher_* routines that used to return int returns
4065 The affected files lib/silccrypt/silccrypt.[ch].
4067 * The same thing was done to silc_hash_* as for silc_cipher_*
4068 routines. Affected files lib/silccrypt/silchash.[ch].
4070 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4071 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4072 Added also silc_pkcs_[un]register[_default] functions.
4073 Removed the data_context from the PKCS API.
4075 * Added silc_hmac_register_default function to register default
4076 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4077 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4078 to unregister all hmacs at once.
4080 * Register the default ciphers, hash functions, PKCSs and HMACs
4081 if client's configuration file does not exist. The affected
4084 * The client did not load the hash functions from the SIM
4085 modules at all. Added support for this. Affected file is
4086 silc/clientconfig.c.
4088 * When decoding public key with silc_pkcs_public_key_decode, check
4089 the supported algorithm only if PKCS are registered. Affected
4090 file lib/silccrypt/silcpkcs.c. The same was done with the
4091 silc_pkcs_private_key_decode.
4093 * Fixed the SILC List routines to keep the list always in order.
4094 It used to change the list's order when traversing the list but
4095 not it preserves the order. Affected file lib/trq/silclist.h.
4097 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4099 * Added the client library to use the SilcSocketConnection's
4100 reference counter (by silc_socket_dup) to prevent the bug that
4101 the socket object may be freed underneath async operation.
4103 * The name resolv library checking fixes in the configure.in.pre.
4106 * Created new version of the protocol drafts for future
4107 development. The -03 drafts are the ones that will be changed
4108 in the trunk now and the -02 will remain as they are.
4110 * Send list of CUMODE notifys to the router when announcing
4111 the channel users to the router. Affected file silcd/server.c.
4112 If the router receiving channel founder CUMODE for a channel
4113 that already has channel founder it will send CUMODE notify
4114 to the sender to remove the channel founder rights from the
4115 announced client. Affected file silcd/packet_receive.c.
4117 * The CUMODE notify may now use Server ID as well as the entity
4118 who changes the mode. Updated protocool specs.
4120 * Updated INSTALL and README files.
4122 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * New web pages in the http://silc.pspt.fi. The pages was
4129 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4131 * Implemented the [DenyConnectin] config section in the server.
4132 Added silc_server_config_denied_conn to check whether incoming
4133 connection is denied. Affected file silcd/serverconfig.[ch].
4135 * Do not check the ports when checking the incoming configuration
4136 data if the port is 0, meaning any. Affected file is
4137 silcd/serverconfig.c.
4139 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * Fixed buffer overflow in silc_string_compare in the file
4142 lib/silcutil/silcutil.c.
4144 * Fixed double free in silc_server_command_leave in the file
4147 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Fixed the version checking in the server. Affected file is
4152 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4154 * Fixed the configuration data fetching when accepting new
4155 connections in the server. Affected file silcd/server.c.
4157 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Added `sender_entry' argument to the function
4160 silc_server_packet_relay_to_channel so that we can check
4161 whether some destination actually belongs to the same route
4162 the sender belongs (ie, we must not resend the packet to the
4163 sender). Affected file silcd/packet_send.[ch].
4165 * Added `servername' field to the SilcClientEntry in the server
4166 to hold the name of the server where client is from. Affected
4167 file is silcd/idlist.h.
4169 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Moved the channel message encrypting in the router betwen
4172 router connections from silc_server_channel_message to the
4173 silc_server_packet_relay_to_channel since we want to check
4174 whether we have anybody channel before encrypting anything.
4175 Affected files silcd/packet_[receive/send].c.
4177 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4179 * Fixed the [AdminConnection] server config section to support
4180 multiple entries. Affected file silcd/serverconfig.c.
4182 * Added support into the server to check the validity of the
4183 incoming connection before executing any KE or authentication
4186 * The connection configuration is now saved to the KE and
4187 connection auth protocol contexts and not fetched anymore in
4188 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4190 * The local hosts listenning address and port is also resolved
4191 now when starting the server. We want to have the socket object
4192 to include the real address and port for the listener. Added
4193 new function silc_net_check_local_by_sock into the files
4194 lib/silcutil/silcnet.[ch].
4196 * Fixed a broadcast bug in server -> do not broadcast if we
4199 * Fixed a routing bug. Do not route broadcast packets ever.
4200 Broadcast packets must be processed always and not routed since
4201 they may be destined to some other host than yourself and thus
4202 would get routed without no good reason. Affected file is
4205 * Added function silc_server_config_is_primary_route to check
4206 whether primary router connection has been configured (a router
4207 configuration that we are initiating). If there is not, we
4208 will assume that there is only two routers in the SILC network
4209 and we will use the incoming router connection as our primary
4210 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4212 * Changed the order of the broadcasting. Broadcast _after_ the
4213 packet has been processed not before. Affected file is
4216 * Fixed a [ClientConnection] parsing bug. The port was never
4217 parsed correctly thus resulting to port 0. Affected file
4218 silcd/serverconfig.c.
4220 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4221 argument and did not set the broadcast packet flag. Affected
4222 file silcd/packet_send.c. Fixed same bug in the function
4223 silc_server_send_notify as well.
4225 * If we receive NEW_ID packet for our own ID in the server, ignore
4228 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Removed the nickname from the Private Message Payload.
4233 Updated the code and the protocol specs.
4235 * Updated protocol specs for submitting to the IETF.
4237 * Tweaked the Random Number Generator a bit. Affected file
4238 lib/silccrypt/silcrng.c. Exported a new function
4239 silc_rng_[global]_add_noise which can be used to add more
4242 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Do not parse packets with different timeout when protocol
4245 is active -> may cause problem with rekey. Affected file
4248 * When server receives signoff notify it must not create
4249 new channel key if the client is on any channels since the
4250 sender of the signoff notify will create it.
4252 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4254 * Added printing of error messages during SKE protocol from the
4255 failure packet sent by server during SKE. Affected file
4258 * Removed the client's failure_callback handling with timeout
4259 and handle it immediately when received.
4261 * The SKE library returned wrong type in SUCCESS and FAILURE
4262 packets. They must be 32 bit MSB not 16 bit MSB.
4264 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * Ok, rewrote the logic of the re-key and now it seems to work.
4267 I tested it on high traffic with frequent re-keys without
4268 problems. Added hmac_receive (and renamed hmac to hmac_send)
4269 in SilcClientConnection in lib/silcclient/client.h and
4270 in SilcIDListData in silcd/idlist.h. Also, removed the
4271 SilcPacketParserContext's cipher and hmac fields as they are
4272 not needed anymore and actually caused some problems when
4273 the ciphers and hmac's changed underneath the packet parser.
4275 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4277 * If re-key protocol is active then process the incoming packets
4278 synchronously since we must assure that icoming packets encrypted
4279 with the old key is processed before the new keys is set to
4280 use. This is true other packets than for REKEY packets.
4281 Affected file silcd/server.c. The same was done to client library
4282 as well, affected file lib/silcclient/client.c.
4284 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Fixed bug in client and server to accept the force send if
4287 the packet is send from silc_[server/client]_packet_process
4288 function. Otherwise the packets are never delivered, oops.
4290 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Disable force sending of packets when REKEY protocol is active.
4293 We must assure that no packet is sent directly when rekey is
4294 performed. All packets must be sent through packet queue.
4295 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4296 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4297 function is silc_[server/client]_packet_send_real to check
4300 * Replaced the SIM paths from example config files to
4301 /usr/local/modules. Also, make install creates now
4302 /usr/local/silc/logs directory to hold all the SILC server
4305 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4307 * Made the configure.in.pre work on Solaris. Patch by salo.
4309 * Made all ciphers compatible with non-x86 machines. Defined
4310 CBC mode macros into lib/silccrypt/ciphers_def.h.
4312 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Fixed the make install.
4316 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4318 * When MAC computation fails the silc_packet_decrypt returned 0
4319 even though it was supposed to return -1. Fixed this. The
4320 affected file is lib/silccore/silcpacket.c.
4322 * Do not replace the config files in /etc/silc (in make install)
4323 if they already exist. Affected file ./Makefile.am.
4325 * Do not send re-key packets immediately but through packet queue.
4326 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4328 * Changed silc_net_check_host_by_sock to return FALSE if the
4329 IP/DNS could not be resolved. Though, it returns the IP address
4330 now even if it could not resolve it (but returns also FALSE).
4331 Affected file lib/silcutil/silcnet.[ch].
4333 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Added silc_pkcs_decode_identifier to decode the public key's
4336 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4337 Added also silc_pkcs_free_identifier. Added also new context
4338 SilcPublicKeyIdentifier.
4340 * Added -S option to the silc client. It is used to dump the
4341 contents of the specified public key file.
4343 * Changed the PKCS api to return the public key length when
4344 setting the public key.
4346 * Fixed a fatal bug in the public and private key file loading.
4347 Affected file lib/silccrypt/silcpkcs.c.
4349 * Execute the packet parsing for client with zero (0) timeout
4350 if the protocol is active. Affected file silcd/server.c.
4352 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Made the key generation options to the silcd program. Added
4355 -C option, equivalent to client's option.
4357 * Added new [ServerKeys] config section to the server. It
4358 configures the server's public and private key.
4360 * Defined generic Public Key Payload into the protocol
4361 specification to send specific type of public keys and
4364 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4365 public key or certificate.
4367 * Implemented the GETKEY command to the server and to the
4368 client library and on user interface.
4370 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Made preliminary `make install' work.
4374 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * Added SilcServerRekey context into silcd/idlist.h.
4378 * Added the PFS support as defined in the specification to the
4379 SKE protocol. Affected files lib/silcske/*.c.
4381 * Added `ske_group' field to the SilcServerRekey context to hold
4382 the number of the SKE group that is used with PFS in re-key.
4383 Affected file silcd/idlist.h.
4385 * Added PFS re-key support to the server. Affected file is
4388 * Added silc_protocol_cancel to cancel execution of the next
4389 state of the protocol. Affected file is
4390 lib/silccore/silcprotocol.[ch].
4392 * Added the re-key support with and without PFS to the client
4393 library. Re-key is performed once in an hour, by default.
4395 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4396 Added silc_client_rekey_callback and silc_client_rekey_final.
4397 Affected files are lib/silcclient/protocol.[ch] and
4398 lib/silcclient/client.[ch].
4400 * Removed the `hmac_key' and `hmac_key_len' fields from the
4401 SilcClientConnection structure; not needed. Affected file is
4402 lib/silcclient/client.h.
4406 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Do not ask whether user wants to use the negotiated private key
4409 for private messages, just use it. Affected file is
4410 silc/local_command.c.
4412 * Added `send_enc_key' and `enc_key_len' fields to the
4413 SilcIDListData structure since they are needed in the re-key
4414 phase. Affected file is silcd/idlist.[ch].
4416 * Implemented the simple re-key protocol into the server.
4417 Affected files silcd/server.c and silcd/protocol.[ch]. The
4418 re-key will be performed once in an hour, by default.
4420 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4421 Added silc_server_rekey, silc_server_rekey_callback and
4422 silc_server_rekey_final.
4424 * Removed Tunneled flag from the protocol. Updated the code
4425 and the specifications.
4427 * Adde `pfs' field to the SilcIDListData to indicate whether
4428 the PFS is to be performed in the re-key. Affected file is
4431 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4434 int64 of at least the xintXX size. If void * is less that 4
4435 bytes uint32 * will be used. Defined bool as boolean.
4437 * Changed _ALL_ unsigned long and unsigned int to uint32,
4438 unsgined short to uint16 in the source tree.
4440 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4441 not handle clients that has entry->data.registered == FALSE.
4442 They are not in the network anymore. Affected file is
4445 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4447 * Implemented the sending of the SERVER_SIGNOFF notify in the
4448 server. Affected file is silcd/server.c.
4450 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4451 Added also silc_notify_payload_encode_args into the
4452 lib/silccore/silcnotify.[ch].
4454 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4455 Affected file silcd/packet_receive.c.
4457 * Implemented the SERVER_SIGNOFF notify handling in the client
4458 library. Affected file lib/silcclient/client_notify.c. Also,
4459 implemnted the printing of the SERVER_SIGNOFF info to the
4460 application. Affected file silc/client_ops.c.
4462 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4463 if the deleting was successful. Affected file silcd/idlist.[ch].
4465 * Added support for public key authentication in the connection
4466 authentication protocol in the client library. Affected file
4467 lib/silcclient/protocol.c.
4469 * Changed the server's silc_idlist_get_clients_by_* interface
4470 to support already allocated array so that new entries may be
4471 added to pre-allocated array. Affected file silcd/idlist.[ch].
4472 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4473 and command replies.
4475 * All command reply functions in the server now calls the
4476 pending command callback even if error occured. This way the
4477 error will be delivered to the client as well. Affected files
4478 silcd/command.c and silcd/command_reply.c.
4480 * Fixed INFO command to return local server's info if no server
4481 was provided. Affected file lib/silcclient/command.c.
4483 * Removed RESTART command for good. Updated the code and the
4486 * Rewrote parts of the task system. It is a bit simpler now.
4487 Removed unsued task priorities. The affected files are
4488 lib/silcutil/silctask.[ch].
4490 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * Moved the USERS printing from the library to the application.
4493 Affected files lib/silcclient/command.c and silc/client_ops.c.
4495 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Added channel key re-key support. The re-key is perfomed
4500 only by the router and is done once in an hour. Added `rekey'
4501 field to the SilcChannelEntry in the server. Affected files
4502 silcd/server.c and silcd/idlist.h.
4504 * Added silc_task_unregister_by_context into the file
4505 lib/silcutil/silctask.[ch].
4507 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4509 * Added SILC_UMODE_GONE mode to indicate when the client is not
4510 present in the SILC network. Added also support to the local
4511 command AWAY that will set this mode. Added support of showing
4512 "xxx is gone" in WHOIS command. The USERS command shows the
4513 gone status as well.
4515 * Fixed setting server and router operator privileges in the
4516 server's UMODE command. Affected file silcd/command.c.
4518 * Merged the SKE KE1 and KE2 payloads into one payload. The
4519 new KE payload is equivalent to the old KE2 payload.
4521 Cleaned up the SKE Start Payload parsing. It now uses the
4522 simple buffer unformatting to do the parsing. A lot faster
4525 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4526 to the SKE that is used to indicate whether both of the SKE
4527 parties should perform authentication. By default only the
4528 responder performs authentication. By setting this flag also
4529 the initiator must do authentication. By default it is unset
4530 since in normal SKE case, client to server connection, only
4531 the responder should do authentication. When doing SKE between
4532 two clients both should perform authentication. Updated the
4533 code and the protocol specs.
4535 * A little fix to IDENTIFY command in the server. Search the
4536 client first by hash not nickname. Affected file is
4539 * Fixed the silc_client_close_connection to support closing
4540 the client to client connections wihtout deleting too much
4541 data. Affected file lib/silcclient/client.c.
4543 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4544 are received if protocol used to be active but is not anymore
4545 the application would crash due to NULL pointer dereference.
4546 Affected files silcd/server.c and lib/silcclient/client.c.
4548 * Added `hash' field to the SilcClientConnection to include
4549 the hash function negotiated in the SKE protocol.
4551 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4552 to set the channel founder authentication data. A client can
4553 claim the founder rights later by providing the authentication
4554 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4555 This way the channel founder can regain the channel founder
4556 privileges even it is left the channel. This works only on
4557 local server and the client must be connected to the same
4558 server to be able to regain the founder rights. Updated the
4559 protocol specs accordingly.
4561 Added support to the CMODE command in the client to set the
4562 founder auth data. Read the README to see how to set it.
4564 Added support to the CUMODE command to claim the founder
4565 rights. Read the README to see how to do it.
4567 Added support for the founder authentication to the Channel
4568 Entry in the server. Affected file silcd/idlist.h.
4570 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4571 server's CMODE command. Affected file silcd/command.c.
4573 * Added the following new functions into lib/silccore/silcauth.[ch]:
4574 silc_auth_get_method and silc_auth_get_data.
4576 * The server now saves the remote hosts public key to the
4577 SilcIDListData pointer. Affected file silcd/protocol.c.
4579 * The normal server now does not remove the channel entry from
4580 the cache if the founder authentication data is set. It used
4581 to remove it if the founder was the last one on the channel on
4582 the server and left the channel. The auth data is saved and
4583 if the channel is re-joined later the old entry is used with
4584 the old auth data. Affected files silcd/command_reply.c and
4587 * Removed the `pkcs' field from the SilcIDListData structure
4588 in the server; it is not used. Affected file silcd/idlist.h.
4590 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4592 * Fixed packet processing on slow links. Partial packets were
4593 never re-processed because the incoming data buffer was cleared
4594 by the application. Application must not directly clear the
4595 sock->inbuf, the packet processing routines handle it. Fixed
4596 this in client library and in server.
4598 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Fixed the WHOIS and IDENTIFY send reply function to really
4601 check whether to send list or just one entry. Affected file
4604 * Cleaned up the LEAVE command's channel key distribution. The
4605 affected file silcd/command.c.
4607 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4608 can enforce the channel mode as well. In that case the ID
4609 includes the ID of the server. The code now enforces the
4610 mode change if the router have different mode than the server.
4612 * The notify client operation with CMODE_CHANGE notify can now
4613 return NULL client_entry pointer if the CMODE was not changed
4614 by client. Application must check for this.
4616 * Added <Server ID> argument to INFO command to support server
4617 info fetching by Server ID.
4619 * Added silc_server_announce_get_channel_users to get assembled
4620 packets of channel users of the specified channel. Affected
4621 file silcd/server.[ch].
4623 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4624 was freed underneath the ID Cache.
4626 * Re-announce clients when the server received CHANNEL_CHANGE
4627 notify from the router. Affected file silcd/packet_send.c.
4629 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4632 crashed since it did not handle the fact that there is no cipher
4633 called "3" and didn't check the error condition. Now fixed.
4635 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4636 flag. It can be used to send message requests.
4638 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4640 * Implemented the RESTART command in the client.
4642 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4643 notice type messages. Added notice printing to the user
4646 * The channel keys are not re-generated if the channel's mode
4647 is PRIVKEY, ie private key on the channel exists. Affected
4648 files silcd/server.c and silcd/command.c.
4650 * Fixed a little bug in channel message delivery when channel
4651 private keys are set in the server. Affected file is
4652 silcd/packet_send.c.
4654 * Changed the setting on channel->on_channel = TRUE from the
4655 silc_client_save_channel_key to the JOIN command reply. The
4656 key payload is not received if the private channel key is set.
4657 Affected file lib/silcclient/command_reply.c and the
4658 lib/silcclient/client_channel.c.
4660 * When the CMODE_CHANGE notify is sent and the channel private
4661 key mode is removed the channel key must be re-generated in
4662 other cells as well. Added this support for the router in the
4663 silcd/packet_receive.c.
4665 * Added new local command NOTICE to send notice message on
4666 channel. Affected file silc/local_command.[ch].
4668 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Added new local command ME to the client. It is used to send
4671 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4672 some action. Affected file silc/local_command.[ch].
4674 * Changed channel_message and private_message client operations
4675 to deliver the message flags to the application. Added also
4676 the `flags' arguments to the silc_client_send_channel_message
4677 and silc_client_send_private_message functions. Affected file
4680 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Redefined the Private Message Payload to support private message
4683 keys and to support the new private message flags. Updated
4684 the protocol specs. Flags makes it possible to have for example
4685 CTCP style messages.
4687 * Added new type SilcPrivateMessagePayload and defined an API
4688 for it in the lib/silcclient/silcprivate.[ch].
4690 * Tested private message private keys successfully. Tested the
4691 private message key set, unset and list commands with the new
4694 * Redefined the Channel Message Payload to include the channel
4695 message flags (equal with private message flags) to support
4696 for example CTCP style messages.
4698 * Defined some of the message (for channel and private message)
4699 flags. Updated the protocol specs and added the flags to the
4700 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4702 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Added SilcKeyAgreementStatus type to the key agreement routines
4705 to indicate the current status and error if one occured.
4706 The status types are defined in the lib/silcclient/silcapi.h.
4708 * Added new local command KEY that is used to set and unset private
4709 keys for channels, set and unset private keys for private messages
4710 with remote clients and to send key agreement requests and
4711 negotiate the key agreement protocol with remote client. The
4712 key agreement is supported only to negotiate private message keys,
4713 it currently cannot be used to negotiate private keys for channels,
4714 as it is not convenient for that purpose.
4716 * Fixed a minor pending callback setting bug in the function
4717 silc_client_get_client_by_id_resolve, now the function works.
4718 Affected file lib/silcclient/idlist.c.
4720 * Added function silc_net_get_local_port to get local bound
4721 port by socket. Added to lib/silcutil/silcnet.[ch].
4723 * Added `sockets' and `sockets_count' fields to the SilcClient
4724 object. They hold the sockets of the listenning sockets in
4725 the client. Listenning sockets may be for example the key
4726 agreement server. Affected file lib/silcclient/client.[ch].
4727 Added functions the silc_client_add_socket and the
4728 silc_client_del_socket. They are exported to the application
4731 * Added ~./silc/clientkeys to support other client's public keys.
4733 * Renamed verify_server_key client operation to verify_public_key
4734 and added one argument to indicate the type of the connection
4735 (server, client etc.).
4737 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4739 * Added silc_server_connection_auth_request to handle the
4740 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4741 silcd/packet_receive.[ch].
4743 * Added silc_server_send_connection_auth_request into the
4744 silcd/packet_send.c to send the connection auth request packet.
4746 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4749 * Fixed the public key authentication in responder side in the
4750 server. The `auth_data' pointer includes the SilcPublicKey
4751 not the path to the public key. Affected file silcd/protocol.c.
4753 * Implemented the public key authentication in the initiator side
4754 in the server. Affected file silcd/protocol.c.
4756 * Removed the [RedirectClient] config section from the server
4757 configuration. Is not needed and I don't want to implement it.
4759 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * Cleaned up the CMODE command in the server. It now works
4762 correctly and supports all the modes defined in the protocol.
4763 Affected file is silcd/command.c.
4765 * Added `hmac_name' field to the SilcChannelEntry in the server
4766 to hold the default HMAC of the channel. It can be set when
4767 creating the channel (with JOIN command). Affected files
4770 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4771 type to indicate the change of the current cipher and hmac
4772 on the channel. Client can safely ignore the <cipher> argument
4773 (if it chooses to do so) since the CHANNEL_KEY packet will
4774 force the channel key change anyway. The <hmac> argument is
4775 important since the client is responsible of setting the new
4776 HMAC and the hmac key into use.
4778 * Fixed the CMODE command in the client library as well.
4780 * Tested CMODE command in router environment successfully.
4782 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Show the version of the remote client (or server) when connecting
4785 to the server. It is logged to the log file. Affected file
4786 is silcd/protocol.c.
4788 * Fixed the KILLED notify handling in the client library. The
4789 client must be removed from all channels when receiving the
4792 Also, do not remove the client entry when giving the KILL
4793 command but when the KILLED notify is received.
4795 * Removed silc_idlist_find_client_by_nickname from the server.
4796 Not needed anymore. Affected files silcd/idlist.[ch].
4798 * Implemented the CHANNEL_CHANGE notify type handling to the
4799 server. Affected file silcd/server.c.
4803 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4817 * Added function silc_server_get_client_resolve to find the
4818 client entry by ID from all ID lists and then resolve it
4819 (using WHOIS) if it cannot be found. Affected file is
4822 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4824 * Implemented the BAN command to the client library.
4826 * The JOIN command in the server now checks the invite list
4829 * Changed the silc_command_reply_payload_encode_va and the
4830 silc_command_payload_encode_va to support that if argument is
4831 NULL it ignores and checks the next argument. Affected file
4832 lib/silccore/silccommand.c.
4834 * Added silc_server_send_notify_ban to send the BAN notify
4835 type between routers.
4837 * Chaned the silc_notify_payload_encode to support that if
4838 argument is NULL it ignores and checks the next argument.
4839 Affected file lib/silccore/silcnotify.c.
4841 * Tested ban lists in router environment successfully.
4843 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4845 * Implemented BAN command to the server, in silcd/command.[ch].
4847 * Removed the BAN and INVITE_LIST modes from the CMODE command
4850 * Added function silc_string_match to regex match two strings.
4851 Affected files lib/silcutil/silcutil.[ch].
4853 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4855 * Redefined parts of the SilcChannelEntry in the server to support
4856 the new ban and invite lists.
4858 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4860 * Redefined the INVITE command. The same command can be used to
4861 invite individuals to the channel but also to manage the invite
4862 list of the channel (to add to and remove from the invite list).
4863 Updated the protocol specs.
4865 * Added new command SILC_COMMAND_BAN that can be used to manage
4866 the ban list of the channel. Updated the protocol specs.
4868 * Removed the channel modes: the SILC_CMODE_BAN and the
4869 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4870 in the CMODE command. The equivalent features are now available
4871 using INVITE and BAN commands. Updated the protocol specs.
4873 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4874 in the network about change in the current ban list. The notify
4875 type is not used by the client.
4877 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4878 support the invite lists.
4880 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Added new function silc_string_regexify that converts string
4883 including wildcard characters into regex string that can
4884 be used by the GNU regex library. Added into the file
4885 lib/silcutil/silcutil.[ch].
4887 Added silc_string_regex_combine to combine to regex strings
4888 into one so that they can be used as one regex string by
4889 the GNU regex library. Added into the file
4890 lib/silcutil/silcutil.[ch].
4892 Added silc_string_regex_match to match two strings. It returns
4893 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4895 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Imported GNU regex to the soruce tree into lib/contrib.
4898 Fixed some compiler warning from the regex.c.
4900 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Fixed MOTD command in the server to work in router environment.
4904 * Fixed the MOTD command in the client library to support
4905 the server argument in the command.
4907 * Added `nickname_len' argument to the silc_idlist_add_client
4908 in the server, as the `nickname' argument may be binary data
4911 * Added silc_idlist_get_channels to return all channels from
4914 * Implemented LIST command to the server. Affected file is
4917 * Implemented the LIST command to the client library and on the
4920 * Added [<user count>] argument to the LIST command reply.
4921 With private channels the user count is not shown.
4923 * Updated TODO and README.
4925 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4927 * The client entry's data.registered must be TRUE even with
4928 global client entry on global client list. The data.registered
4929 is used to check whether the client is anymore in the network,
4930 for example with WHOWAS command so it must be valid.
4932 * Fixed the WHOWAS command in the server. It now actually works
4933 in router environment. Added function into silcd/command_reply.c
4934 silc_server_command_reply_whowas_save.
4936 * Added silc_idlist_purge function to the silcd/idlist.c
4937 to periodically purge the ID Cache.
4939 * Fixed INFO command in the server. It works now in router
4940 environment. Added <server name> argument to the INFO command
4941 reply. Updated the protocol specs.
4943 * Fixed minor bug in silc_idcache_purge to not purge if the
4944 expire value is zero.
4946 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4947 they were buggy because of the WHOWAS information.
4949 * Fixed local command MSG to handle the async resolving of
4950 the remote client properly. It used to fail the first MSG.
4951 Affected file silc/local_command.c.
4953 * Added `data_len' field to SilcIDCache context.
4955 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Update TODO. Todo in commands in the server.
4959 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4961 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4962 used by routers as broadcast packet to inform other routers
4963 about the changed user mode.
4965 Implemented the notify handling in the server. Affected file is
4966 silcd/packet_receive.c. Added the function
4967 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4969 * Added new generic Channel Payload and deprecated the New Channel
4970 Payload. The New Channel Payload is now the generic Channel
4973 * Added new argument `mode' to the silc_server_send_new_channel
4974 as it is required in the Channel Payload now.
4976 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4977 and created a new and real SilChannelPayload to represent the
4978 new generic Channel Payload. Implemented the encode/decode
4979 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4981 * Added silc_server_get_client_channel_list to return the list
4982 of channels the client has joined for WHOIS command reply.
4983 Affected file silcd/server.[ch].
4985 * Implemented the channel list sending in the WHOIS command reply
4986 in server and in the client.
4988 Implemented the channel list displaying on the user interface
4989 as well. Affected file silc/client_ops.c.
4991 * Added silc_channel_payload_parse_list to parse list of Channel
4992 Payloads. It returns SilcDList list of SilcChannelPayloads.
4993 Client for example can use this function to parse the list of
4994 channels it receives in the WHOIS command reply. The caller
4995 must free the list by calling silc_channel_payload_list_free.
4996 Affected files lib/silccore/silcchannel.[ch].
4998 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5000 * Added one new argument <user mode> to the WHOIS command reply
5001 to return the mode of the user in SILC. Updated the protocol
5004 Implemented it to the server and client.
5006 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Fixed the mode printing on the user interface on joining.
5009 Affected file silc/client_ops.c.
5011 * Implemented the UMODE command and user modes in general to the
5012 client library and to the user interface.
5014 * Implemented the UMODE command to the server.
5016 * The server now sends UNKNOWN_COMMAND error status if client sends
5017 unknown command. Affected file silcd/command.c.
5019 * All server commands now handle the command identifier the right
5020 way when sending the command reply to the client. The client can
5021 use to identify the command replies with the identifier.
5023 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Added silc_server_get_client_route to resolve the route to
5026 the client indicated by the client ID. Affected file is
5029 * Added silc_server_relay_packet as general function to relay
5030 packet to arbitrary destination. This deprecates functions
5031 like _send_private_message_key, _relay_notify etc. Affected
5032 file is silcd/packet_send.[ch].
5034 Removed silc_server_send_key_agreement,
5035 silc_server_send_private_message_key and
5036 silc_server_packet_relay_notify functions from the file
5037 silcd/packet_send.[ch].
5041 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5042 server. Affected file silcd/packet_receive.[ch].
5044 * Implemented the KILL command to the client. Implemented the
5045 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5046 Affected files lib/silcclient/command[_reply].c and
5047 lib/silcclient/client_notify.c. Implemented the KILL notify
5048 printing in the user inteface.
5050 * Fixed a lot silc_parse_nick memory leaks from the client
5051 library in the file lib/silcclient/command.c.
5053 * Changed the silc_server_send_notify_on_channels's `sender'
5054 argument from SilcSocketConnection to SilcClientEntry to
5055 check the sender as entry and not as connection object and not
5056 to send to the client provided as argument. The affected file
5057 is silcd/packet_send.[ch].
5059 * The notify packets that are destined directly to the client used
5060 to not to be processed by the server. Now changed that and the
5061 server processes all notify packets. After relaying the packet
5062 to the client the notify packet is processed in the server.
5064 * The silc_server_free_client_data now checks whether there is
5065 pending outgoing traffic for the client and purges the data to
5066 the network before removing the client entry.
5068 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5071 an client is killed from the SILC Network. Updated the protocol
5074 Added new function silc_server_send_notify_killed to the
5075 silcd/packet_send.[ch].
5077 * Added function silc_server_packet_relay_notify to relay notify
5078 packets that are destined directly to a client. In this case
5079 the server does not process the notify packets but merely relays
5080 it to the client. Affected file silcd/packet_send.[ch].
5082 Added also silc_server_packet_process_relay_notify to check
5083 whereto relay the notify. Affected file is
5084 silcd/packet_receive.[ch].
5086 * Implemented the KILL command to the server.
5090 * Added the backup schema desgined last fall to the protocol
5091 specs for everyone to see. The specification is in the
5092 *-spec-xx.txt draft and the packet type definitions for the
5093 backup routers is in *-pp-xx.txt draft. Thusly, added also
5094 new packet type SILC_PACKET_CELL_ROUTERS.
5096 * A big security problem in the implementation discovered. The
5097 signoff of an client did not cause new channel key generation
5098 which it of course should've done. The channel keys must be
5099 always re-generated when client leaves (or signoffs) the channel.
5100 The silc_server_remove_from_channels funtion now handles
5101 the channel key re-generation.
5103 * Added `sender' argument to the silc_server_send_notify_on_channels
5104 to not to send the client provided as argument. Affected file
5105 silcd/packet_send.[ch].
5107 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Implemented OPER and SILCOPER commands into the server and
5112 * Added silc_auth_verify and silc_auth_verify_data to verify
5113 the authentication directly from the authentication payload.
5114 It supports verifying both passphrase and public key based
5115 authentication. Affected file lib/silccore/silcauth.[ch].
5117 * Added `hash' field to the SilcIDListData structure. It is the
5118 hash negotiated in the SKE protocol. Affected file is
5121 * Slight redesigning of the SilcAuthPayload handling routines.
5122 Do not send SilcPKCS but SilcPublicKey as argument.
5124 * Implemented the public key authentication support to the
5125 serverconfig. The public key is loaded from the provided path
5126 and saved as authentication data to void * pointer. Thus,
5127 changed the unsigned char *auth_data to void *auth_data;
5129 * Fixed SHUTDOWN command to send the reply before the server
5130 is shutdown. :) Affected file silcd/command.c.
5132 * Fixed fatal bug in CONNECT command. The hostname was invalid
5133 memory and server crashed. Affected file silcd/command.c.
5135 * Fixed fatal bug in CLOSE command. The server_entry became
5136 invalid but was referenced later in the command. Affected file
5139 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Fixed fatal bug in failure packet handling. Server ignored
5142 the failure and thus crashed when it came.
5146 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5149 that the command may be executed only once in (about) 2 seconds.
5150 The old SILC_CF_LAG flag is same but allows command bursts up
5151 to five before limiting.
5153 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5154 server code. Various commands now includes the CF_LAG_STRICT
5155 flag to disallow any kind of miss-use of the command.
5157 * Fixed the silc_buffer_unformat to not to allocate any data
5158 if the length of the data is zero. It used to allocate the
5159 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5161 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Changed the format of AdminConnection configuration section
5164 in the server. Added username of the admin to the format.
5165 Affected files silcd/serverconfig.[ch].
5167 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5168 to return admin configuration data by host, username and/or
5171 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Implemented WHOWAS command to the server. Added the functions:
5175 silc_server_command_whowas_parse,
5176 silc_server_command_whowas_send_reply,
5177 silc_server_command_whowas_from_client and
5178 silc_server_command_whowas_from_server
5180 * Added <Client ID> argument to the WHOWAS command reply. Updated
5181 the protocol specs accordingly.
5183 * Implemented WHOWAS command and command_reply to the client
5186 Implemented the WHOWAS printing on the user interface.
5188 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Added new argument to the WHOWAS command reply, the real name.
5191 It is an optional argument. Updated the protocol specs.
5193 * Added SilcIDCacheDestructor callback that is registered when
5194 the SilcIDCache is allocated. The callback is called when
5195 an cache entry in the ID Cache expires, or is purged from the
5196 cache. Added into lib/silccore/idcache.[ch].
5198 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5199 to destruct the client entries when the cache entry expires.
5200 Other ID Cache's in server and in the client library ignores
5203 * If the ID Cache entry's `expire' field is zero then the entry
5204 never expires. Added boolean `expire' argument to the
5205 silc_idcache_add function in the lib/silccore/idcache.[ch].
5206 If it is TRUE the default expiry value is used.
5208 * Added silc_server_free_client_data_timeout that is registered
5209 when client disconnects. By default for 5 minutes we preserve
5210 the client entry for history - for WHOWAS command.
5212 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5214 * Added support to the server to enforce that commands are not
5215 executed more than once in 2 seconds. If server receives
5216 commands from client more frequently, timeout is registered
5217 to process the commands. Affected file silcd/command.c.
5218 Added new function silc_server_command_process_timeout.
5220 * Changed NICK_NOTIFY handling in client library to check that
5221 if the client's nickname was changed, so there is no need to
5222 resolve anything from the server.
5224 * Removed error printing from the WHOIS and IDENTIFY commands.
5225 If error occurs then it is ignored silently in the client library.
5226 The application, however, may map the received error to
5227 human readable error string. The application currently maps
5228 the NO_SUCH_NICKNAME error to string.
5230 * Made the command status message public to the application. Moved
5231 them from lib/silcclient/command_reply.c to
5232 lib/silcclient/command_reply.h. The application can map the
5233 received command status to the string with the
5234 silc_client_command_status_message function.
5236 * Added check to the server to check that client's ID is same
5237 as the Source ID in the packet the client sent. They must
5240 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Added dist-bzip hook to the Makefile.am to make bzip2
5243 compressed distributions.
5245 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5247 * Server now enforces the maximum length for the nickname and
5248 the channel as protocol specification dictates. 128 bytes for
5249 nickname and 256 bytes for channel name.
5251 * Moved the WHOIS printing to the application. The client libary
5252 does not print out the WHOIS information anymore, the application
5253 must do it. Renamed silc_client_command_reply_whois_print to
5254 the silc_client_command_reply_whois_save.
5256 The client's idle time is also sent to the application now, and
5257 the idle is shown on screen.
5259 * Added silc_client_command_reply_identify_save to save the
5260 received IDENTIFY entries.
5262 * Do not check for channel private keys in message sending and
5263 reception if the channel does not have the PRIVKEY mode set.
5264 Affected file lib/silclient/client_channel.c.
5266 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5269 just surfaced after chaning the JOIN procedure.
5271 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Added silc_client_get_clients_by_list to get client entries
5274 from Client ID list, that is returned for example by JOIN
5275 and USERS command replies. The application should use this
5276 function for example when JOIN command reply is received to
5277 resolve the clients already on the channel (library does not
5278 do that anymore as USERS command reply is not used in the JOIN
5279 procedure anymore). Affected files lib/silcclient/silcapi.h and
5280 lib/silcclient/idlist.c.
5282 * JOIN command reply and USERS command reply returns now SilcBuffer
5283 pointers instead of unsigned char pointers when returning
5284 the client list and mode list.
5286 * Added <Client ID> argument to the JOIN command reply, mainly
5287 for the server to identify for which client the command was
5288 originally sent. Updated protocol specs accordingly.
5290 * Added SilcDlist private_key pointer to the SilcChannelEntry
5291 in the client to support the channel private keys. Affected
5292 file is lib/silcclient/idlist.h.
5294 * Added SilcChannelPrivateKey argument to the function
5295 silc_client_send_channel_message so that application can choose
5296 to use specific private ke if it wants to. If it is not provided,
5297 the normal channel key is used, unless private keys are set.
5298 In this case the first (key that was added first) is used
5299 as the encryption key.
5301 * Implemented the support for channel private key handling.
5302 Implemented the following functions:
5304 silc_client_add_channel_private_key,
5305 silc_client_del_channel_private_keys,
5306 silc_client_del_channel_private_key,
5307 silc_client_list_channel_private_keys and
5308 silc_client_free_channel_private_keys
5310 Affected file lib/silcclient/client_channel.c.
5312 * Added the support for the private keys in the channel message
5313 sending and encryption and in the message reception and
5314 decryption. Affected funtions are
5315 silc_client_send_channel_message and silc_client_channel_message.
5317 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Added SKE's key verify callback to the client library's
5320 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5322 * Removed the statement that server (or router) must send USERS
5323 command reply when joining to the channel so that the client
5324 knows who are on the channel. Instead, the client list and
5325 client's mode list is now sent in the JOIN command reply to the
5326 client who joined channel. This is better solution.
5328 * Added function silc_server_get_users_on_channel and function
5329 silc_server_save_users_on_channel to the silcd/server.[ch].
5331 * Removed function silc_server_command_send_users from the
5334 * Do not show topic on the client library anymore. The topic is
5335 sent in the command reply notify to the application and the
5336 application must show the topic now.
5338 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Added client searching by nickname hash into the IDENTIFY and
5341 WHOIS commands in the server as they were clearly missing from
5342 them. Affected file is silcd/command.c.
5344 * Fixed a bug in private message receiving in the client library.
5345 The remote ID was freed and it wasn't supposed, now it is
5348 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Minor fix to the channel payload; allocate the data area, as it
5351 needs to be of specific length.
5353 * If the key agreement port is zero then the operating
5354 system will define the bound port. Affected files are
5355 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5357 * Added new function silc_channel_payload_decrypt into the file
5358 lib/silccore/silcchannel.[ch].
5360 * Moved the channel message etc, check from silc_packet_decrypt
5361 to applications. The library calls now a generic
5362 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5363 when the packet is either normal or special. This was done to
5364 allow more wide range of checking that was not allowed when
5365 the code was in library. Now applications can do virtually any
5366 checks to the packet and return to the library the decision how
5367 the packet should be processed. Affected files are
5368 lib/silccore/silcpacket.[ch].
5370 Added silc_server_packet_decrypt_check to the server and
5371 silc_client_packet_decrypt_check to the client library.
5373 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5374 to send with specified source and destination information.
5376 * Channel message delivery between routers was broken after the
5377 channel key distribution was fixed earlier. The channel key
5378 was used be to distributed to other routers as well which is not
5379 allowed by the protocol. Now this is fixed and channel keys
5380 really are cell specific and the channel message delivery between
5381 routers comply with the protocol specification.
5383 * Fixed various commands in server to check also the global list
5384 for the channel entry and not just the local list. The affected
5385 file silcd/command.c.
5387 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Added assert()s to buffer formatting and unformatting routines
5390 to assert (if --enable-debug) when error occurs. Affected
5391 file: lib/silcutil/silcbuffmt.c.
5393 * Changed to auto-reconnect to check whether the remote host is
5394 router and register the re-connect timeout if it is. It used
5395 to check that whether we are normal server, but router must do
5396 auto-reconnect with another router as well. Affected file
5399 * Removed the [<key len>] option from CMODE command as the cipher
5400 name decides the key length, nowadays. See the defined ciphers
5401 from the protocol specification.
5403 * Added [<hmac>] option to the CMODE command to define the HMAC
5404 for the channel. Added SILC_CMODE_HMAC channel mode.
5406 * Added [<hmac>] option for the JOIN command so that user can
5407 select which HMAC is used to compute the MACs of the channel
5410 * Added Hmac field to the Channel Message Payload. The integrity
5411 of plaintext channel messages are now protected by computing
5412 MAC of the message and attaching the MAC to the payload. The
5413 MAC is encrypted. Now, it is clear that this causes some
5414 overhead to the size of the packet but rationale for this is that
5415 now the receiver can verify whether the channel message decrypted
5416 correctly and also when private keys are set for the channel the
5417 receiver can decrypt the packet with several keys and check from
5418 the MAC which key decrypted the message correctly.
5420 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5421 lib/silccrypt/silccipher.[ch].
5423 * Added silc_hash_len to return the digest length into the
5424 lib/silcrypt/silchash.[ch].
5426 * Rewrote parts of Silc Channel Payload interface in the
5427 lib/silccore/silcchannel.[ch]. The encode function now also
5428 encrypts the packet and parse function decrypts it.
5430 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5432 * Fixed a minor formatting bug in the SKE's key material processing.
5433 It actually might have processed the keys wrong way resulting
5436 * Redefined the mandatory HMAC algorithms and added new algorithms.
5437 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5438 and hmac-md5 truncated to 96 bits. The mandatory is now
5439 hmac-sha1-96. Rest are optional (including the one that used
5440 to be mandatory). Rationale for this is that the truncated HMAC
5441 length is sufficient from security point of view and can actually
5442 make the attack against the HMAC harder. Also, the truncated
5443 HMAC causes less overhead to the packets. See the RFC2104 for
5446 * Added new [hmac] configuration section. The SKE used to use
5447 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5448 is of course wrong. The official names that must be proposed in
5449 the SKE are the ones defined in the protocol specification
5450 (hmac-sha1-96 for example). The user can configure any hmac
5451 using any hash function configured in the [hash] section. At
5452 least, the mandatory must be configured.
5454 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5456 * Added HMAC list to the SKE proposal list. It has now both
5457 hash algorithm list and HMAC list. This makes the protocol
5458 incompatible with previous versions. The SKE now seems to work
5459 the way it is supposed to work, for the first time actually.
5461 * Defined plain Hash algorithms to the protocol specification.
5464 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Implemented support for key agreement packets into the server.
5467 Added functions silc_server_key_agreement and
5468 silc_server_send_key_agreement. Other than these functions,
5469 server has nothing to do with this packet.
5471 * Added support for private message key packets into the server.
5472 Added functions silc_server_private_message_key and
5473 silc_server_send_private_message_key.
5477 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5478 called in the protocol's final callback instead in the END
5479 protocol state. This makes a little more sense and in the same
5480 time in client we can use the same protocol routines for normal
5481 key exchange and to key agreement packet handling as well.
5483 * Added to both client's and server's KE protocol context the
5484 SilcSKEKeyMaterial pointer to save the key material. We will
5485 bring the key material to the protocol's final callback by doing
5486 this. The final callback must free the key material.
5488 * Added SKE's packet_send callback into client's KE protocol
5489 context so that the caller can choose what packet sending function
5490 is used. This way we can use different packet sending when
5491 doing normal SKE when doing key agreement packet handling (in
5492 the key agreement packet handling we do not want to encrypt
5495 * Implemented the responder side of the key agreement routines
5496 in the client. The client can now bind to specified port and
5497 accept incoming key negotiation. The key material is passed
5498 to the application after the protocol is over.
5500 * Implemented the processing of incoming Key Agreement packet
5501 in the client. Added function silc_client_key_agreement to
5504 * Implemented the intiator side of the key agreement routines
5505 in the client. The client can now initiate key agreement with
5506 another remote client. The key material is passed to the
5507 application after the protocol is over.
5509 * Created client_keyagr.c to include all the key agreement
5512 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5513 SILC_TASK_CALLBACK except that it is not static.
5515 * Created client_notify.c and moved the Notify packet handling
5516 from the client.[ch] into that file.
5518 * Created client_prvmsg.c and moved all private message and
5519 private message key routines from the client.[ch] into that file.
5521 * Create client_channel.c and moved all channel message and
5522 channel private key routines from the client.[ch] into that file.
5524 * Changed silc_client_get_client_by_id_resolve to resolve with
5525 WHOIS command instead of IDENTIFY command, in the file
5526 lib/silclient/idlist.c.
5528 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Implemented the SKE's responder side to the Client library.
5532 * When FAILURE is received to the protocol do not trust it
5533 blindly. Register a timeout to wait whether the remote closes
5534 the connection as it should do it, only after that process the
5535 actual failure. This was changed to both client and server.
5537 * Added client_internal.h to include some of the structures
5538 there instead of client.h in lib/silcclient/.
5540 * Added function silc_task_unregister_by_callback to unregister
5541 timeouts by the callback function.
5543 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Some "Incomplete WHOIS info" errors has been appearing on the
5546 log files. Took away the entry->userinfo check from WHOIS
5547 reply sending. The entry->userinfo is now " " if client did not
5548 provide one. I thought this was fixed earlier but something
5549 is wrong still. Let's see if the error still appears.
5551 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Fixed a minor bug in the login when the channel key is
5554 re-generated in the server. It used to generate the key in
5555 wrong order and thus caused problems in the channel traffic.
5557 * Fixed a minor bug in channel key distsribution after
5558 KICK command. The key was not sent to the router even though
5561 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Added silc_ske_process_key_material_data as generic routine
5564 to process any key material as the SILC protocol dictates. The
5565 function is used by the actual SKE library but can be used by
5566 applications as well. This relates to the private message keys
5567 and the channel private keys since they must be processed the
5568 same way the normal SILC session keys. The protocol dictates
5569 this. Affected files: lib/silcske/silcske.[ch].
5571 Added also silc_ske_free_key_material to free the
5572 SilcSKEKeyMaterial structure.
5574 * Defined silc_cipher_set_key function to set the key for
5575 cipher without using the object's method function. The affected
5576 files: lib/silccrypt/silccipher.[ch].
5578 * Implemented silc silc_client_add_private_message_key,
5579 silc_client_add_private_message_key_ske,
5580 silc_client_del_private_message_key,
5581 silc_client_list_private_message_keys and
5582 silc_client_free_private_message_keys functions in the
5585 Added functions silc_client_send_private_message_key to send
5586 the Private Message Key payload and silc_client_private_message_key
5587 to handle incoming Private Message Key payload.
5589 * Added Cipher field to the Private Message Key payload to set
5590 the cipher to be used. If ignored, the default cipher defined
5591 in the SILC protocol (aes-256-cbc) is used.
5593 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Removed lib/silcclient/ops.h file.
5597 Redefined parts of the SILC Client Library API. Created new
5598 file silcapi.h that deprecates the ops.h file and defines the
5599 published Client Library API. Defined also private message key
5600 API and channel private key API into the file.
5602 This is the file that the application must include from the
5603 SILC Client Library. Other files need not be included by
5604 the application anymore.
5606 * Added new key_agreement client operation callback and also
5607 defined the Key Agreement library API for the application.
5609 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5612 is used by clients to request key negotiation between another
5613 client in the SILC network. If the negotiation is started it
5614 is performed using the SKE protocol. The result of the
5615 negotiation, the secret key material, can be used for example
5616 as private message key.
5618 Implemented the Key Agreement payload into the files
5619 lib/silccore/silauth.[ch].
5621 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Redefined ciphers for the SILC protocol. Added some new ciphers
5624 and defined the key lengths for the algorithms. Changed the
5625 code accordingly. The default key length is now 256 bits.
5627 * Fixed SKE key distribution function silc_ske_process_key_material
5628 when the key length is more than 128 bits. The default key
5629 length in SILC is now 256 bits.
5631 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5632 to indicate unsupported algorithm.
5634 * Renamed rijndael.c to aes.c and all functions as well.
5636 * Fixed a long standing channel key setting bug in client library.
5637 Weird that it has never surfaced before.
5639 * Fixed bug in channel deletion. If the entire channel is removed
5640 then it must also delete the references of the channel entry
5641 from the client's channel list as the client's channel entry and
5642 the channel's client entry share same memory.
5644 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Implemented CONNECT and SHUTDOWN commands in the client.
5648 * Implemented CLOSE command to the client.
5650 * Added the function silc_idlist_find_server_by_name into the
5651 files silcd/idlist.[ch].
5653 Added the function silc_idlist_find_server_by_conn into the
5654 files silcd/idlist.[ch].
5656 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * DIE command was renamed to SHUTDOWN. Updated the both code
5661 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5662 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5664 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5667 * Added function silc_server_create_connection function to create
5668 connection to remote router. My server implementation actually
5669 does not allow router to connect to normal server (it expects
5670 that normal server always initiates the connection to the router)
5671 so the CONNECT command is only good for connecting to another
5674 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5677 or some other client was kicked from the channel.
5679 Implemented the handling of the notify type to both client
5682 Implemented silc_server_send_notify_kicked to send the KICKED
5683 notify. It is used to send it to the server's primary router.
5685 * Implemented the KICK command into server and client.
5687 * Added `query' argument to the silc_idlist_get_client function
5688 to indicate whether to query the client from server or not if
5691 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5692 to indicate that the client is not channel founder.
5696 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Removed the rng context from SilcPacketContext structure and
5699 changed that the packet routine uses the Global RNG API.
5701 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5703 * Added support for quit message that client can "leave" on the
5704 channel when it quits the SILC. It is ditributed inside the
5705 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5707 Added silc_server_free_client_data that will take the
5708 signoff message as argument.
5710 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5712 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Updated parts of the protocol specification to keep it up
5717 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5719 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5720 payloads in one packet.
5722 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5723 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5724 use now the new List flag.
5726 * Also deprecated the following packet types: REPLACE_ID,
5727 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5729 * Added list support for Notify packet in server.
5731 * Added silc_server_send_notify_channel_change to send the
5732 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5733 the silc_server_send_replace_id.
5735 * Added silc_server_send_notify_nick_change to send the
5736 NICK_CHANGE notify type. Deprecates the function
5737 silc_server_send_replace_id.
5739 * Added silc_server_send_notify_join to send the JOIN notify type.
5740 Deprecates the function silc_server_send_new_channel_user.
5742 * Added silc_server_send_notify_leave to send LEAVE notify type.
5743 Deprecates the function silc_server_send_remove_channel_user.
5745 * Added silc_server_send_notify_cmode and
5746 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5747 types. Deprecates the silc_server_send_set_mode function.
5749 * Added SERVER_SIGNOFF notify type to indicate that server has
5750 quit. This means that all clients on the channel from that
5751 server will drop. This can be also used when netsplit happens.
5753 Deprecated REMOVE_ID packet type since it is not needed anymore
5756 Added silc_server_send_notify_server_signoff to send the
5757 SERVER_SIGNOFF notify type. Deprecates the function
5758 silc_server_send_remove_id.
5760 Added also silc_server_send_notify_signoff to send the
5761 SIGNOFF notify type.
5763 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5764 SILC protocol from this day on. Changed the protocol
5765 specification as well.
5767 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5768 notify type. It is used between routers to notify about
5769 topic changes on a channel.
5771 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5774 * Partly updated the protocol specification to comply with the
5775 changes now made. It is still though a bit outdated.
5777 * The JOIN notify type now takes one extra argument <Channel ID>.
5778 The packet used to be destined to the channel but now the
5779 JOIN type may be sent as list thus it is impossible to
5780 destine it to any specific channel. By adding this argument
5781 it is again possible.
5783 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5785 * Added CREDITS file. The CHANGES and CREDITS file will appear
5786 in the distribution as well.
5788 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5791 types in the server's silcd/packet_receive.c.
5793 * Implemented CMODE and CUMODE to work in router environment.
5795 * Fixed minor encoding and decoding buglet from the
5796 lib/silccore/silcmode.c.
5798 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5801 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5803 * Changed all SilcConfigServer* and silc_config_server* to
5804 SilcServerConfig* and silc_server_config*, respectively.
5807 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Associated the ID (client or server ID) to the Authentication
5810 Payload to avoid any possibility of forging. Updated the
5811 protocol specification and the code accordingly.
5813 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * The RSA key length is now save to the RsaKey context in the
5816 key generation process in lib/silccrypt/rsa.c. The key length
5817 is now used to figure out the maximum size of the block allowed
5818 to be encrypted/signed.
5820 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5821 is equivalent to the silc_mp_mp2bin but does not allocate any
5824 * Changed silc_mp_mp2bin API to take length argument. If it is
5825 non-zero then the buffer is allocated that large. If zero, then
5826 the size is approximated using silc_mp_sizeinbase, which however
5829 * Created Global RNG API which is global RNG that application can
5830 initialize. After initializing, any routine anywhere in the
5831 code (including library) can use RNG without allocating a new
5832 RNG object. This was done to allow this sort of use of the
5833 RNG in code that has no chance to allocate RNG object. All
5834 applications currently allocate this and many routines in the
5835 library use this. Affected file lib/silccrypt/silcrng.[ch].
5837 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5838 it to use the Global RNG API.
5840 * Defined Authentication Payload into protocol specification that
5841 is used during SILC session to authenticate entities. It is
5842 used for example by client to authenticate itself to the server
5843 to obtain server operator privileges.
5845 Implemented this payload into the lib/silccore/silcauth.[ch].
5846 Implemented also routines for public key based authentication
5847 as the new protocol specification dictates.
5849 Moved definitions of different authentication methods from
5850 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5852 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5853 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5854 silc_pkcs_verify_with_hash functions into the file
5855 lib/silccrypt/silcpkcs.[ch].
5857 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5859 * The client entry's userinfo pointer must be always valid.
5860 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5861 will fail since it requires the userinfo. Now, the userinfo
5862 is allocated as "" if actual userinfo does not exist. Actually,
5863 it must exist and it is totally Ok to drop client connections
5864 that does not announce the userinfo. However, we will make
5865 this workaround for now.
5867 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5868 to return the remote port by socket.
5870 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5873 SILC_SERVER_PENDING_EXEC and added an new macro
5874 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5875 data or when error occurs while processing the pending command.
5877 Added new argument `destructor' into silc_server_command_pending
5878 and to the SilcServerCommandPending object. This destructor is
5879 now called after calling the pending callback or if error occurs
5880 immediately. If error occurs the actual pending callback won't
5881 be called at all - only the destructor. The destructor may be
5882 NULL if destructor is not needed.
5884 All this applies for client library code as well. Similar
5885 changes were made there as well for the pending commands.
5887 In the client, the application must now allocate the
5888 SilcClientCommandContext with the silc_client_command_alloc
5891 * Added reference counter to the SilcServerCommandContext. Added
5892 function silc_server_command_alloc and silc_server_command_dup
5895 Same type of functions added to the client library for the same
5898 * Removed the cmd_ident from IDListData away since it is now
5899 global for all connections. It is the command identifier used
5900 in command sending and with pending commands. The affected file
5903 * Added reference counter to the SilcSocketConnection objecet to
5904 indicate the usage count of the object. The object won't be
5905 freed untill the reference counter hits zero. Currently only
5906 server uses this, and client ignores it. The client must be
5907 set to use this too later. The affected files are
5908 lib/silccore/silcsockconn.[ch]. Added also the function
5909 silc_socket_dup to increase the reference counter.
5911 This was mainly added because it is possible that the socket
5912 is removed underneath of pending command or other async
5913 operation. Now it won't be free'd and proper DISCONNECTING
5914 flags, etc. can be set to avoid sending data to connection that
5915 is not valid anymore.
5917 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5918 the connection. After that it sets SILC_SET_DISCONNECTED.
5919 It is, however, possible that the socket data is not still freed.
5920 The silc_server_packet_process now checks that data is not
5921 read or written to connection that is DISCONNECTED. The socket
5922 get's freed when the reference counter hits zero.
5924 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Changed the client operation API: channel_message operation's
5927 `sender' is now the client entry of the sender, not the nickname
5928 and the `channel' is the channel entry, not the channel name.
5930 In the private_message operation the `sender' is now also the
5931 client entry of the sender not the nickname.
5933 Affected file is lib/silcclient/ops.h and all applications
5934 using the client operations.
5936 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Moved the calling of ops->connect() from connect_to_server_final
5939 into receive_new_id functin since that is the point when the
5940 client is actually allowed to send traffic to network. The
5941 affected file is lib/silcclient/client.c.
5943 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5946 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5947 (if needs broadcasting) instead of broadcasting the packets one
5948 by one which would make a burst in the network traffic.
5950 * Added `broadcast' argument to the functions in silcd/server.[ch]
5951 silc_server_create_new_channel[_with_id] to indicate whether
5952 to send New Channel packet to primary router.
5954 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Added new function into the silcd/server.[ch] files:
5957 silc_server_create_new_channel_with_id to create new channel with
5958 already existing Channel ID.
5960 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5961 lib/silccore/silcpacket.h. This packet is used t send list of
5962 Set Mode payloads inside one packet. Server uses this to set
5963 the modes for the channels and clients on those channels, that it
5964 announced to the router when it connected to it. The protocol
5965 specification has been updated accordingly.
5967 * The silc_server_new_channel did not handle the packet coming
5968 from normal server as it normally does not send that. However,
5969 when it announces its channels it does send it. Implemented
5970 the support for that.
5972 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5973 into the file lib/silccore/id.h.
5975 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5977 * Fixed memory leaks in the functions silc_idlist_del_client,
5978 silc_idlist_del_channel and silc_idlist_del_server in the file
5979 silcd/idlist.c. All of those leaked like a sieve.
5981 * Fixed some small memory leaks in the client's function
5982 silc_client_notify_by_server.
5984 * Added functions into silcd/server.c: silc_server_announce_clients,
5985 silc_server_announce_channels and silc_server_announce_server.
5986 These functions are used by normal and router server to announce
5987 to its primary router about clients, channels and servers (when
5988 router) that we own. This is done after we've connected to the
5991 These functions effectively implements the following packet types:
5992 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5993 and SILC_PACKET_NEW_ID_LIST.
5995 * Added new functions into the silcd/packet_receive.[ch]:
5996 silc_server_new_id_list, silc_server_new_channel_list and
5997 silc_server_new_channel_user_list to handle the incoming
5998 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6000 * Added support of changing Channel ID in the function
6001 silc_server_replace_id. If the server that announces a channel
6002 to the router already exists in the router (with same name but
6003 with different Channel ID), router is responsible to send
6004 Replace ID packet to the server and force the server to change
6005 the Channel ID to the one router has.
6007 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6008 client that the Channel ID has been changed by the router. The
6009 normal server sends this to the client. Client must start using
6010 the new Channel ID as the channel's ID.
6012 Implemented handling of this new type into lib/silcclient/client.c
6013 into the function silc_client_notify_by_server.
6015 * Added new function silc_idlist_replace_channel_id into the files
6016 silcd/idlist.[ch] to replace the Channel ID.
6018 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6020 * Call silc_server_command_identify_check always when processing
6021 the IDENTIFY command in silcd/command.c
6023 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6026 send keepalive packets. The packet can be sent by clients,
6027 servers and routers.
6029 Added function silc_socket_set_heartbeat into the file
6030 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6031 If not set, the heartbeat is not performed. The actual
6032 heartbeat is implemented in the low level socket connection
6033 library. However, application is responsible of actually
6036 Added silc_server_send_heartbeat to send the actual heartbeat
6037 packet into silcd/packet_send.[ch]. Server now performs
6038 keepalive with all connections.
6040 * Added silc_task_get_first function into lib/silcutil/silctask.c
6041 to return the timeout task with shortest timeout. There was a bug
6042 in task unregistration that caused problems. TODO has been
6043 updated to include that task system must be rewritten.
6045 * The client library will now resolve the client information when
6046 receiving JOIN notify from server for client that we know but
6047 have incomplete information.
6049 * Rewrote parts of silc_server_remove_from_channels and
6050 silc_server_remove_from_one_channel as they did not remove the
6051 channel in some circumstances even though they should've.
6053 * Encryption problem encountered in server:
6055 The LEAVE command used to send the Channel Key packet to the
6056 router immediately after generating it. However, the code
6057 had earlier sent Remove Channel user packet but not immediately,
6058 ie. it was put to queue. The order of packets in the router
6059 was that Channel Key packet was first and Remove Channel User
6060 packet was second, even though they were encrypted in the
6061 reverse order. For this reason, MAC check failed. Now, this
6062 is fixed by not sending the Channel Key packet immediately but
6063 putting it to queue. However, this is more fundamental problem:
6064 packets that are in queue should actually not be encrypted
6065 because packets that are sent immediately gets encrypted
6066 actually with wrong IV (and thus MAC check fails). So, packets
6067 that are in queue should be encrypted when they are sent to
6068 the wire and not when they put to the queue.
6070 However, the problem is that the current system has not been
6071 designed to work that way. Instead, the packet is encrypted
6072 as soon as possible and left to the queue. The queue is then
6073 just purged into wire. There won't be any fixes for this
6074 any time soon. So, the current semantic for packet sending
6077 o If you send packet to remote host and do not force the send
6078 (the packet will be in queue) then all subsequent packets to the
6079 same remote host must also be put to the queue. Only after the
6080 queue has been purged is it safe again to force the packet
6083 o If you send all packets immediately then it safe to send
6084 any of subsequent packets through the queue, however, after
6085 the first packet is put to queue then any subsequent packets
6086 must also be put to the queue.
6088 Follow these rules and everything works fine.
6090 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6092 * Added new function silc_server_remove_clients_by_server to
6093 remove all client entries from ID list when the server connection
6094 is lost. In this case it is also important to invalidate all
6095 client entires as they hold the invalid server entry. This
6096 fixes fatal bug when server has lost connection and will reconnect
6099 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Made some sanity checks to silc_server_daemonise like to check
6102 whether the requested user and group actually exists.
6104 * Added sanity check to SKE's silc_ske_responder_finish to check
6105 that the public and private key actually is valid.
6107 * Invalidate the client's nickname when receiving Replace ID
6108 packet and the Client ID is being replaced. This means that the
6109 server will query the nickname if someone needs it (client)
6112 * Sort the ID Cache in client library when the ID Cache data
6113 has changed (needs sorting).
6115 * Do not allow for SILC client to create several connections to
6116 several servers. The client does not support windows right now
6117 and generating multiple connections causes weird behaviour.
6119 Irssi-silc client does support windows and can handle several
6120 connections without problems, see: www.irssi.org and SILC plugin.
6122 * Fixed some places where client was added to the IDList. The
6123 rule of thumb is following (in order to get everything right):
6124 If the client is directly connected local client then the
6125 `connection' argument must be set and `router' argument must be
6126 NULL to silc_idlist_add_client function. If the client is not
6127 directly connected client then the `router' argument must
6128 bet set and the `connection' argument must be NULL to the
6129 silc_idlist_add_client function.
6131 * The funtion silc_server_packet_send_local_channel actually did
6132 not check whether the client was locally connected or not. It
6133 does that now. Fixed a bug related to LEAVE command.
6135 * Fixed Remove Channel User payload parsing bug in server's
6136 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6138 * The server's silc_server_save_channel_key now checks also the
6139 global ID list for the channel as it might not be in the local
6140 list. Fixed a bug related to LEAVE command.
6142 * Is this the end of the [<unknown>] buglet that has been lurking
6143 around for a long time? A little for loop fix in server's
6144 silc_server_command_whois_parse that is used by both IDENTIFY
6145 and WHOIS command. At least, this was a clear bug and a cause
6146 of one type of [<unknown>] buglet.
6148 * WHOIS and IDENTIFY commands call the function
6149 silc_server_command_[whois/identify]_check function even if
6150 we are not router server.
6152 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6154 * Added --with-gmp configuration option. If set the GMP
6155 is always compiled in the SILC source tree. If not set then
6156 it is checked whether the system has the GMP3 installed. If
6157 it has then the GMP won't be compiled (the system's headers
6158 and library is used), if it doesn't have it then the GMP is
6159 compiled in the SILC source tree.
6161 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6163 * Changed RSA private exponent generation to what PKCS #1
6164 suggests. We try to find the smallest possible d by doing
6165 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6166 not security fix but optimization.
6168 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6170 * Added new config entry [Identity] to fork the server and run
6171 it as specific user and group. A patch from Bostik.
6173 * Imported Dotconf configuration library into lib/dotconf.
6174 This will be used to create the SILC configuration files later.
6175 It will appear in the distsribution after this commit.
6177 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * A big code auditing weekend happening. Auditing code for
6180 obvious mistakes, bugs and errors. Also, removing any code
6183 Removed files for being obsolete:
6185 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6186 inline in the file lib/silcutil/silcbuffer.h)
6188 o lib/silcutil/silcbufutil.c (the header has inline versions)
6190 Changed code to fix possible error conditions:
6192 o The buffer formatting routines now check that the destination
6193 buffer really has enough space to add the data. This applies for
6194 both buffer formatting and unformatting
6195 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6196 unformatting was changed to accomodate following rules:
6197 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6198 sent to the function while XXX_*STRING will not allocate or copy
6199 the data into the buffer. Instead it sets the pointer from the
6200 buffer into the pointer sent as argument (XXX_*STRING used to
6201 require that the pointer must be allocated already). This change
6202 makes this whole thing a bit more consistent and more optimized
6203 (note that the data returned in the unformatting with XXX_*STRING
6204 must not be freed now). The routines return now -1 on error.
6206 o Tried to find all code that use buffer_format and buffer_unformat
6207 and added return value checking to prevent formatting and
6208 especially unformatting errors and possible subsequent fatal
6211 o Changed ske->x and ske->KEY to mallocated pointers in
6212 lib/silcske/silcske.h. Fixed possible data and memory leak.
6214 o Added return value checking to all *_parse* functions. Fixed
6215 many memory leaks as well.
6217 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6218 so that buffer overflows would not happen. All code now also
6219 checks the return value as it can fail.
6221 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6223 * Added reconnection support to server if the normal server looses
6224 its connection to the router (for example if router is rebooted).
6225 The server performs normal reconnection strategy implemented
6226 to the server. Affected file silcd/server.c.
6228 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6230 * Added new packet type SILC_PACKET_SET_MODE that is used to
6231 distribute the information about changed modes (for clients,
6232 channels and clients channel modes) to all routers in the
6233 network. Updated the protocol specification accordingly.
6235 Added functions into silcd/packet_send.c and
6236 silcd/packet_receive.c: silc_server_send_set_mode,
6237 silc_server_set_mode.
6239 Added new files silcmode.[ch] into lib/silccore that implements
6240 the encoding and decoding of Set Mode Payload. Added new type
6241 SilcSetModePayload. Moved the definitions of different modes
6242 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6244 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Oops, a little mistake in server's connection authentication
6247 protocol. The protocol is not ended with FAILURE but with
6248 SUCCESS if the authentication is Ok. :) Affected file is
6251 * Implemented NICK_CHANGE notify handling in server in the file
6252 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6253 the local clients on the channel. After the changing nickname
6254 in router environment snhould work and the [<unknown>] nickname
6255 should appear no more.
6257 The silc_server_replace_id function that receives the Replace ID
6258 payload now sends the NICK_CHANGE notify type also in the file
6259 silcd/packet_receive.c
6261 * Changed WHOIS and IDENTIFY command to support the maximum amount
6262 of arguments defined in protocol specs (3328 arguments). This
6263 fixed a bug that caused problems when there were more than three
6266 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Added extra parameter, command identifier, to the
6269 silc_client_send_command so that explicit command identifier
6272 Changed that ID list routines uses specific command identifier
6273 when sending WHOIS/IDENTIFY requests to the server so that they
6274 can be identified when the reply comes back.
6276 Affected files lib/silcclient/command.[ch],
6277 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6279 * Added `sender' argument to silc_server_packet_send_to_channel
6280 to indicaet the sender who originally sent the packet to us
6281 that we are now re-sending. Ignored if NULL. Affected file
6282 silcd/packet_send.[ch].
6284 * Added some server statistics support in silcd/server_internal.h
6285 SilcServerStatistics structure and around the server code. Also
6286 send some nice statistics information when client is connecting
6289 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6291 * Fixed channel ID decoding in server's JOIN command reply in
6292 silcd/command_reply.c
6294 * Fixed braodcasting of replace ID payload to not to send it if
6295 we are standalone server in silcd/packet_receive.c.
6297 * Fixed all channel message sending routines to not to send
6298 packets to clients that has router set, since they are routed
6299 separately in the same function earlier. Affects file
6300 silcd/packet_send.c and all channel packet sending functions.
6302 * In USERS reply, res_argv[i] are not allocated, the table
6303 is allocated. Thus changed that free the table, not its
6306 * In server's whois_check and identify_check if the client is
6307 locally connected do not send any WHOIS commands - they are not
6310 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Fixed some minor bugs in client when sending WHOIS command. The
6313 arguments was in wrong order.
6315 * Removed statis function add_to_channel from server in
6316 silcd/command.c that was previously used with the joining but
6319 * Tested USERS command in router environment successfully with two
6320 routers, two servers and two clients.
6322 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6324 * Reorganized the USERS command and command reply in client library
6325 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6326 When the command is given by user we register a pending command
6327 callback that will reprocess the command after the reply has been
6328 received from the server. When reprocessing the packet we then
6329 display the information. Thus, the USERS information is displayed
6330 now in the command callback instead of in the command reply
6331 callback. The processing of the command is same as previously
6332 when server has sent the command reply in the JOINing process.
6334 * Added to USERS command in silcd/command_reply.c to join the client,
6335 we didn't use to know about, to the channel after we've created
6336 a client entry for it. Also, for clienet we did know already still
6337 check whether it is on the channel or not and add it if not.
6339 * Removed silc_server_command_join_notify as the function and its
6342 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6344 * Changed the client's pending command handling to the same as the
6345 server's pending command handling. It is also now possible to
6346 execute command reply functions from other command reply
6347 function as the function callbacks for commands and command
6348 replies are one and same. The pending commands are not static
6349 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6350 in client connection context. Thus, pending commands are server
6351 connection specific as it is convenient.
6353 Changed the function silc_client_command_pending and
6354 silc_client_command_pending_del and added new function
6355 silc_client_command_pending_check. Removed the
6356 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6359 * Added cmd_ident, current command identifier, to the client
6360 connection context in lib/silcclient/client.h to keep track on
6361 command identifiers used in command sending. Client's command reply
6362 function handling now supports the mandatory command identifiers.
6364 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6365 funtions in client to fully support pending command callbacks.
6367 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6368 as one of the arguments to the application in the command reply
6371 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6372 before first releasing SILC but came back. Now it is removed again
6373 and should come back nomore. The FORWARDED flag was used only
6374 by the JOINing procedure by forwarding the command packet to router.
6375 Now, the JOINing procedure has been changed to more generic (due
6376 to various router environment issues) and FORWARDED is not needed
6377 anymore for anything. The protocol specification is yet to be
6380 Now, removed silc_server_packet_forward from server and the flag
6381 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6383 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6385 * Renamed NAMES command to USERS command. The NAMES was named that
6386 due to historical reasons. Now it is renamed. Also, rewrote
6387 parts of the USERS command. The nickname list is not sent anymore
6388 by the server. Only Client ID and mode lists are sent in the USERS
6389 command. Changed this also to the protocol specification.
6391 The client now resolves the names and stuff after it receives
6392 the USERS list from the server when joining to the channel.
6394 * WHOIS and IDENTIFY commands has been changed to support multiple
6395 Client ID's per command. One can now search for multiple users
6396 in the network by sending only one WHOIS or IDENTIFY command.
6397 Changed the code and the protocol specifications.
6399 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6400 uses silc_server_command_whois_parse to parse the request. */
6402 * If normal server, do not parse the WHOIS and IDENTIFY requests
6403 before sending it to the router. Saves some time.
6405 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6407 * Fixed JOIN command on client library. Wrong number of arguments
6408 used to crash the client.
6410 * Added silc_server_channel_has_global function to check whether
6411 channel has global users or not.
6413 * Added silc_server_channel_has_local function to check whether channel
6414 has locally connected clients on the channel.
6416 * The silc_server_remove_from_one_channel now checks whether the
6417 channel has global users or not after given client was removed from
6418 the channel. It also checks whether the channel has local clients
6419 on the channel anymore. If it does not have then the channel entry
6420 is removed as it is not needed anymore.
6422 * The silc_server_notify now checks on JOIN notify whether the joining
6423 client is one of locally connected or global. If it is global then
6424 the channel has now global users on the channel and that is marked
6425 to the channel entry. Also, it now saves the global client to
6426 global list who is joining and JOINs it to the channel. This is
6427 for normal server, that is.
6429 Changed silc_server_send_notify_on_channel,
6430 silc_server_packet_relay_to_channel and
6431 silc_server_packet_send_to_channel check if we are normal server
6432 and client has router set (ie. global client) do not send the
6433 message to that client, as it is already routed to our router.
6435 * Implemented LEAVE notify type handling in silc_server_notify
6438 * Tested LEAVE command in router environment successfully. Tested
6439 with two routers, two servers and two clients.
6443 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6445 * Implemented SIGNOFF notify type handling in silc_server_notify
6448 * silc_server_remove_id now removes the client entry from all channels
6449 it has joined and thusly sends SIGNOFF notify type.
6451 * Rewrote the NAMES list generation in server by removing two excess
6452 loops. The lists are created now inside one loop.
6454 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6456 * silc_server_remove_channel_user checks now also global list
6457 for channel and client.
6459 * silc_server_new_channel_user checks now both local and global
6460 list for channel and client. Fixed a bug in client id decoding.
6461 Used to decode wrong buffer.
6463 * silc_server_channel_message checks now both local and global
6464 list for channel entry.
6466 * Tested channel joining (hence JOIN) in router environment
6467 successfully. Tested with two routers, two servers and two
6470 * Tested channel message sending in router environment successfully.
6472 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6474 * Added silc_server_save_channel_key into server.[ch] to save the
6475 received channel key in Channel Key payload processing. It is
6476 also used in JOIN command reply handling.
6478 Equivalent function silc_client_save_channel_key added into
6479 client.[ch] into client library.
6481 * Changed JOIN command reply to send information whether the channel
6482 was created or not (is existing already) and the channel key
6483 payload. Changed protocol specs accordingly.
6485 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6486 the request was sent by ID and not by nickname. Crashed on
6489 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6491 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6492 now correctly save the received data.
6494 * silc_server_free_sock_user_data now notifies routers in the
6495 network about entities leaving the network.
6497 At the same time implemented functions silc_server_remove_id
6498 and silc_server_send_remove_id to receive and send REMOVE_ID
6499 packets. The packet is used to notify routers in the network
6500 about leaving entities. The ID removed will become invalid in
6503 * Added function silc_idlist_del_server into server. Removes and
6504 free's server entry from ID list.
6506 * silc_server_private_message function now checks, if we are router,
6507 that the destination ID really is valid ID, naturally.
6509 * In router when NEW_ID packet is received (for new client) the
6510 hash of the Client ID is saved in the ID Cache but the
6511 client->nickname is set to NULL, instead of putting the hash
6514 IDENTIFY command now also checks that client->nickname must be
6515 valid. If it is not if will request the data from the server who
6516 owns the client. Added new function
6517 silc_server_command_identify_check.
6519 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6520 to set the command to already allocated Command Payload.
6522 * Tested private message sending in router environment with two
6523 routers, two servers and two clients. Fixed minor bugs and now
6526 * Fixed segfault from client's NAMES command. Used to crash if
6529 * Forwarded packets must not be routed even if it is not destined
6530 to the receiver. Changed server code comply with this.
6532 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6534 * Added `require_reverse_mapping' boolean value to ServerParams
6535 structure. If TRUE (not default) the server will require that
6536 the connecting host has fully qualified domain name.
6538 If the reverse mapping is not required and hostname could not be
6539 found the IP address is used as hostname.
6541 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Implemented version string checking to both client and server.
6544 The check is incomplete currently due to the abnormal version
6545 strings used in development version of SILC.
6547 * Changed all command functions in server to use the new
6550 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Changed char *data to unsigned char *data in ID Cache system to
6553 support binary data as ID Cache data. Changed code to support
6554 binary data in lib/silccore/idcache.c.
6556 * Renamed silc_server_packet_relay_command_reply to
6557 silc_server_command_reply as it is normal packet receiving
6558 function. Rewrote the function to accept command replys for
6559 servers and not only for clients.
6561 * Mark remote router always as registered server if we are connecting
6562 to it. Otherwise, commands sent by the router to us are ignored.
6564 * All ID List find routines now returns the ID Cache Entry pointer
6565 as well if requested.
6567 * WHOIS command works now in router environment, tested with two
6568 routers, two servers and two clients.
6570 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6571 in router environment (as it is almost equivalent to WHOIS) but
6572 hasn't been tested thoroughly. Added new functions:
6574 silc_server_command_identify_parse
6575 silc_server_command_identify_send_reply
6576 silc_server_command_identify_from_client
6577 silc_server_command_identify_from_server
6579 * Disabled route cache adding because adding two different ID's with
6580 same IP replaces the old cache entry thus giving wrong route.
6581 The entry->router->connection is always the fastest route anyway
6582 so route cache may not be needed. Of course, new routes maybe
6583 established after receiving the ID when the entry->router->connection
6584 might not be anymore the most optimal.
6586 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6588 * Add route cache for received ID for fast routing.
6590 * Added silc_server_packet_route to route received packet on router
6591 that is not destined to us.
6593 * Renamed silc_server_get_route to silc_server_route_get.
6595 * Added id_string and id_string_len fields into SilcServer to
6596 include encoded ServerID for fast comparing without excess
6597 encoding of the ID's.
6599 * Cleaned up WHOIS command on server side. Added following static
6602 silc_server_command_whois_parse
6603 silc_server_command_whois_check
6604 silc_server_command_whois_send_reply
6605 silc_server_command_whois_from_client
6606 silc_server_command_whois_from_server
6608 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6609 arguments in command replies. All command functions should be
6610 updated to use this macro.
6612 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6614 * Minor typo fixes on command reply handling on server.
6616 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6618 * Added silc_server_command_add_to_channel internal routine to add
6619 the client to the channel after router has created the channel and
6620 sent command reply to the server.
6622 * Added generic silc_server_send_command to send any command from
6625 * Use static buffer with ID rendering instead of duplicating data.
6627 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Fixed a channel user mode bug when joining to a channel server gave
6630 everybody channel founder rights, oops.
6632 * We mark ourselves as the router of the incoming server connection
6633 if we are router ourselves. This way we can check in some packet
6634 sending functions whether it is locally connected server. For
6635 incoming router connections we put NULL.
6637 * For router sending packets locally means now always sending the
6638 packet cell wide; to local clients and local servers. For normal
6639 server sending packet locally means sending it to only local
6642 * Fixed the JOIN command to really work in router environment. If the
6643 channel is created it is always created by the router. Router is
6644 also responsible of making the initial joining to the channel,
6645 sending JOIN notify to the sending server and distributing
6646 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6647 does not exist server doesn't do anything else but forward the
6648 command to the router which performs everything.
6650 * Added silc_server_send_channel_key function to send the Channel Key
6653 * Added silc_server_create_channel_key to create new channel key. The
6654 channel key is now re-generated everytime someone joins or leaves
6655 a channel, as protocol dictates. Note: channel->key_len is the
6658 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6660 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6661 packet_receive.[ch] to separate packet sending and receiving
6662 routines. The server.[ch] now includes everything else including
6663 actual packet processing (writing and reading data) and other
6666 Renamed silc_server_private_message_send_internal to
6667 silc_server_send_private_message. The routine is still though
6668 used only to relay private messages as server does not send
6669 private messages itself.
6671 Renamed silc_server_new_channel to silc_server_create_new_channel
6672 and added new function sicl_server_new_channel that handles the
6673 incoming New Channel packet. Added also new sending function
6674 silc_server_send_new_channel to send New Channel Payload.
6676 * Added new function silc_server_notify to process incoming notify
6677 packet to the server/router. Server may then relay the notify
6678 to clients if needed.
6680 * Added new function silc_server_new_channel_user to process incoming
6681 New Channel User packet. Router will redistribute the packet and
6682 send JOIN notify to its local clients and locally connected servers
6683 if needed. Normal server will send JOIN notify to its local client
6684 on same channel when received this packet. Added also corresponding
6685 sending function silc_server_send_new_channel_user to sent the
6688 * Added boolean route argument to send_notif_to_channel and
6689 packet_send_to_channel functions to attempt to route the packet
6690 if it is TRUE and send only locally if it is FALSE.
6692 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * silc_server_replace_id now broadcasts the received replace ID
6695 packet if it is not broadcast packet already. The router must
6696 broadcast to inform other routers about changed ID.
6698 * Added backpointer to server's router into SilcServer context in
6699 silcd/server_internal.h.
6701 * Fixed silc_server_packet_broadcast to send correct broadcast
6704 * The channel key is now distributed to the local client as soon
6705 as it is received from the router (in router environment) so that
6706 no other packet may be sent for the channel until client has
6709 * silc_server_remove_channel_user now broadcasts the received
6710 Remove Channel User packet if it is not broadcast packet already.
6711 The router must broadcast to inform other routers about removed
6714 * Added users field into SilcPacketContext that is a reference count
6715 of the context. One can increase the reference count by calling
6716 silc_packet_context_dup which is now changed to just increase the
6717 reference count instead of duplicating the data. The reference
6718 count is decresed by calling silc_packet_context_free that will
6719 free the data after the reference count hits zero.
6721 For now on the packet context and everything allocated into it
6722 (including the raw packet from network) must be freed by calling
6723 the new silc_packet_context_free function. Added also new function
6724 silc_packet_context_alloc that must be used now to allocate the
6725 context. This also means that if a routine is asynchronous from
6726 silc_[client/server]_packet_parse_type the packet context must
6727 be duplicated by calling silc_packet_context_dup. Otherwise it
6728 gets free'd after silc_[client/server]_packet_parse_type returns.
6729 Also, one must remember that if packet is duplicated then its
6730 reference count must be decresed by calling the free function as
6731 many times as it was duplicated.
6733 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6734 from both client and server.
6736 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6738 * Made joining to a channel working in router environment.
6740 * Cleaned up JOIN command on server side and create function
6741 silc_server_command_join_channel internal routine to make the
6744 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6746 * Changed silc_command_pending list to SilcDList. Also, added
6747 `ident' field to SilcServerCommandPending structure to identify
6748 the reply and to call correct callback.
6750 Added silc_server_command_pending_check function to replace the
6751 corresnponding macro. The silc_command_pending list is not
6754 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6755 to set identifier to previously allocated Command Payload. It
6756 is used to set identifier for command when resending Command
6759 * Added silc_command_payload_encode_payload to encode Command
6760 Payload buffer from SilcCommandPayload structure.
6762 * Added silc_argument_payload_encode_payload to encode Argument
6763 payload buffer from SilcArgumentPayload structure.
6765 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6767 * Changed WHOIS command to support router connection on server side.
6768 The whois request is always sent to router unless the server is
6769 standalone server. After server has received the reply from the
6770 router will it send the reply to the client.
6772 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6773 broadcast received broadcast packet. The function is used only
6774 by router. The broadcast packet is always sent to the router's
6777 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6778 render given ID to printable string, for log files for example.
6780 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * Made basic router to router connections working. At least they
6783 can now connect to each other but nothing really works the way
6784 they are supposed - yet.
6786 * Added new initiator token to RouterConnection configuration
6787 file in silcd/serverconfig.[ch]. It is used to tell whether we
6788 are the initiator to the remote router or whether we'll expect
6789 the other end to connect.
6791 * Moved registering of listener task to silc_server_init, hence
6792 the server starts listenning as soon as it is run, even if it
6793 does not have connections to other routers. Let's see how well
6796 * Changed default connection retry timeouts for more suitable in
6799 * Removed cipher and such arguments from silc_idlist_add_client
6800 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6801 Added new function silc_idlist_add_data to add the keys and stuff
6804 * Added SilcIDListData structure and added it to SilcClientEntry
6805 and SilcServerEntry as their first field in the structure. This
6806 way we can explicitly cast the ID entries to the SilcIDListData
6807 structure and get common data for the entries. In past, we had
6808 to first check what type of connection it is and then cast it to
6809 correct ID entry type. Now, we can directly cast the opaque
6810 pointer to the SilcIDListData (no matter what ID entry it actually
6811 is) and get the data needed.
6813 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6815 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6816 in some circumstances even if threre were timeout tasks, though not
6817 IO tasks, but tasks anyway. Now fixed.
6819 * Defined SilcServerConnection structure to hold connection specific
6820 stuff about directly connected servers and routers. The definition
6821 is currently in silcd/server_internal.h. I thought about having
6822 a bit more important role fro this struct but for now it is used
6823 only when connecting to other server (or router actually).
6825 * Added connecting retry support in server when connecting to
6826 router(s). The retry feature implement exponential backoff
6827 algorithm. Also, added SilcServerParams structure to hold default
6828 parameters for server. For now, it include these retry settings
6829 and are hard coded. After server is moded to be as Silc Server
6830 Library this structure will be more important.
6832 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6834 * Changed client librarys channel->clients table to SilcList and
6835 changed code accordingly.
6837 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6839 * Changed client's channel table to SilcList and changed code
6840 accordingly. Also changed SilcChannelClientEntry to include back-
6841 pointer to the channel so that client entry can use that structure
6842 as list as well and we have fast cross-reference to the channel.
6843 This change dramatically decreased the complexity of channel
6844 handling with client entry and vice versa (removed one extra
6845 loop when searching for channel entry from many functions).
6847 * Changed server->sim from table to SilcDList and changed code
6850 * NAMES command can now be used from user interface. It will show
6851 the user list on the channel, neatly.
6853 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6854 Code now saves realname of the user if it becomes available.
6856 * Renamed configure.in to configure.in.pre and made ./prepare
6857 script to automatically add correct version string to
6858 configure.in which it creates from configure.in.pre.
6860 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * NAMES command reply now shows users mode with the nickname when
6865 * Moved silc_client_ch[u]mode[_char] functions from
6866 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6867 place sucks, they are utility functions and should be in some
6870 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6872 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6875 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Added TRQ (efficient deque and list library) into lib/trq. This is
6880 a very good list library that is currently used in the SILC. Defined
6881 SilcList API over the library because I didn't like the API very
6882 much. See lib/trq/silclist.h for the API and examples of how to
6883 use the API. Fixed various places in the code to use the new
6884 SilcList API. The SilcList is meant for lists that has a structure
6885 already defined as a list. It is not suitable to add just some
6886 context to the list (in TRQ, the context is the list actually).
6888 So, I defined SilcDList that can be used for the purpose where
6889 predefined list structure does not exit. This can be used as
6890 such list. Now some context just can be added to the SilcDList.
6891 Currently this list is not used in the SILC just yet, though there
6892 are a lot places where this can replace dynamically allocated
6893 tables and I will fix these places, later, to use SilcDList.
6894 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6895 and use TRQ internally).
6897 Also fixed some annoying warning messages that the original TRQ
6898 code generated. Also minor changes to TRQ's Makefile.in.
6900 * Added support for querying by Client ID to both WHOIS and
6901 IDENTIFY commands into server, as required by the protocol.
6903 * Removed method function pointers from SilcBuffer structure. They
6904 weren't used to anything and just increased the context size for
6905 no good reason. This change also made silc_buffer_alloc and
6906 silc_buffer_free functions inline functions.
6908 * Disabled command flooding detection support until it's fixed so
6909 that it accepts commands in but does not execute them more than once
6912 * Added silc_net_localhost(), to return local hostname, into
6913 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6914 that must be initialized before calling silc_client_init.
6916 * Added new function: silc_server_send_notify_on_channels to send
6917 notify messages to all channels client has joined. It is assured
6918 that the message is sent only once per client.
6920 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6921 lib/silcutil/silcutil.[ch] as silc_format function. The new
6922 function is generic and is used by server as well, not only by
6923 the logging routines.
6925 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6926 the provided version string was not acceptable. Added new function:
6927 silc_ske_check_version into lib/silcske/silcske.h. The function
6928 must be implemented by the application (client or server) and it
6929 does not reside in the SKE library. The function checks the version
6930 string remote end sent.
6932 * Added back pointers (to opaque context and to SilcSocketConnection)
6933 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6935 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6936 duplicate packet context structure.
6938 * Changed `notify' client operation to send same arguments as client
6939 receives from server except for ID's. ID's are mapped to correct
6940 ID entry and that is returned. Also, if channel entry is not sent
6941 by server but the notify is for channel the channel entry is sent
6942 to application (otherwise application doesn't know that it is for
6943 channel (library gets it from packet's Destination ID)).
6945 * Added silc_client_remove_from_channels into client library to
6946 remove a client from all channels it has joined to. Used when
6947 received SIGNOFF notify from server. Added also new function
6948 silc_client_replace_from_channels to replace old ID entry with
6949 new ID entry on all channels. Used when received NICK_CHANGE
6952 * Fixed ID Cache list handling in silc_idlist_get_client in
6953 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6954 to get (or query) client by ID.
6956 * Updated TODO list.
6958 * Added connection authentication status message defined by the
6959 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6960 support for these into the code in client and server side.
6962 * Added generic function silc_client_send_command to send any command
6963 with variable argument list. Application should use this function
6964 to send commands if the command functions provided by the library
6965 does not suite for the application's user interface needs.
6967 * Added new `failure' client operation. Application is notified about
6968 received failure packet if client is executing a protocol. In this
6969 case the protocol's execution has failed.
6971 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6972 is required by the protocol.
6974 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6975 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6978 * Added status flag to SilcSKE object to indicate realtime status
6979 of the SKE protocol.
6981 * Application receives now exactly same command reply arguments as
6982 the library receives from server. However, if ID is received the
6983 corresponding ID entry is returned to the application (eg. Client
6984 ID is mapped to correct SilcClientEntry entry and that is returned).
6985 Changed command_reply client operation due to this change.
6987 * Changed all ID's in commands and in command replys as ID Payloads.
6988 Change affected both client and server side codes.
6990 All ID's sent in SILC network (with execption of ID's in SILC
6991 Packet header) are sent in ID Payload to support variable length
6994 * Server now notifies nick changes and notifies all clients on
6995 the channels about the new nickname (about the new Client ID,
6998 * Implemented CMODE command to change channel modes. Supports all
6999 channel modes defined by the protocol specs except ban and invite
7000 lists. (Also, private channel key mode is supported but support for
7001 setting private channel key in client is missing, thus, this mode
7002 has no effect on client side (except that server requires that the
7003 client uses private channel key and normal channel traffic does not
7006 Also, invite mode works per se, but INVITE command does not work
7007 yet correctly, so you can set channel as invite only channel but
7008 inviting clients to the channel does not work (it is yet to be
7009 thought what's the best way to do it).
7011 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7012 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7013 Implemented CUMODE command to change user's mode on the channel.
7014 Supports all modes defined by the protocol specs.
7016 * Added NAMES command reply to return users modes on the channel.
7018 * Removed unnecessary and slow ciphers from lib/silccrypt.
7020 * Set SO_KEEPALIVE option to connection sockets by default.
7022 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7024 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7025 redefined the Notify Payload into protocol specs.
7027 * Added silc_id_payload_parse_id to get ID directly from raw
7030 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7032 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7033 accept searching by Client ID as well.
7035 * Added support for LEAVE and SIGNOFF notify types in client library.
7037 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7038 to parse ID Payload from raw data.
7040 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7042 * Added flags parameter into silc_ske_assemble_security_properties
7043 function in lib/silcske/silcske.[ch].
7045 * Changed notify client operation to fit better for notify messages
7046 sent by server. The notify payload received from server is now
7047 passed to the application (after parsing it to SilcNotifyPayload).
7048 It is application's responsibility to retrieve the arguments
7049 from the payload and show the message the way it wants. The message
7050 sent by server is implementation specific.
7052 * Changed public keys to comply with the protocol specification.
7053 Old public keys are not supported anymore and are not compatible.
7055 * Removed nickname from Channel Payload as the latest draft removed
7056 it. The client must resolve the nickname from the NAMES command
7057 reply received when it joined the channel.
7059 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7061 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7063 * Fixed some errors in protocol specification drafts.
7065 * Created lib/silccore/silcnotify.c to implement Notify Payload
7066 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7067 generic payloads described by protocol specifications. The file
7068 includes implementations for ID Payload and Argument Payload.
7070 * Changed Command Payload implementation to use the new Argument
7071 Payload. Changed command_xxxx_payload to command_payload_xxxx
7072 to comply with SILC coding conventions.
7074 * Added suppport for Argument Payload handling in Notify Payload
7075 implementation as protocol requires it. Added the new support
7076 into server and client lib as well.
7078 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7080 * Added support for multiple nicknames on same channel. [n] is
7081 added locally to the nickname if there are more than one same
7082 nicknames on the channel.
7084 * Server now sends all nicknames that matched WHOIS request.
7085 Client also shows the list received from server.
7087 * Added TOPIC command to client side. User can now set and show
7088 current topic on channel.
7090 * Added MOTD command to client and server. Also, server sends the
7091 motd when client connects to the server.
7093 * Changed version strings to comply ISO 8601.
7095 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7097 * Fixed protocol error handling in client library. It should now
7098 cope even if the SKE fails for some reason.
7100 * Made new protocol specification drafts for submitting to IETF.
7102 * Implemented TOPIC command to server in silcd/command.c.
7104 * Added two new notify types into lib/silccore/silcnotify.h:
7105 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7106 notify nickname change and topic setting/change on a channel.
7108 * API change of command_reply operation in client library. The
7109 application gets now the status type received from server as well.
7111 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7113 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7115 * Cras fixed and optimized the packet handling even further and
7116 it should work now. Minor change to the prototype of function
7117 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7119 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7121 * Added new function into lib/silcutil/silcschedule.[ch]:
7122 silc_schedule_with_fd to select() a specified fd. The function
7123 returns after timeout expires or data arrives or goes. The
7124 function is used by packet routines to wait that all data is
7125 received from network.
7127 * Fixed data reading from network in lib/silccore/silcpacket.c.
7128 The code now assures that all data is read from the fd and then
7129 continues packet processing. This was a bug fix since the code
7130 used to drop some data in some circumstances.
7132 * Added new function into lib/silcclient/client.[ch]:
7133 silc_client_start_key_exchange to start key exchange after
7134 connection has been established to server. The code internally
7135 now uses this funtion but its main purpose was to provide it
7136 for applications that perform their own connecting. After
7137 application has created a connection it merely calls this
7138 function to start the key exchange between client and server.
7139 The library takes care of everything else after that.
7141 Updated also lib/silcclient/README to explain the usage of
7144 * Do not send to application information that connection has
7145 been established. Application gets notified it by connect
7148 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7150 * Applied cras's patch to add silc_schedule_one function. The
7151 function runs scheduler once and returns.
7153 * Fixed the scheduler after cras messed it up. The timeout
7154 handling works now as it's supposed to work.
7156 * Added into lib/silccore/ silcnotify.h to include notify
7157 message types support. Changed silc_server_send_notify*
7158 functions, in server.[ch], to support those new notify types.
7159 Added the support for the notify types into client library,
7160 as well. Added new notify client operation into ops.h in
7163 * Changed silc_server_packet_send_to_channel to send normal
7164 packets instead of just channel message packets. The function
7165 is now used to send the notify packets to channels. It is not
7166 used to send channel message packets anymore, as server never
7169 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7170 va_arg()s as it seems to require it nowadays. I guess, if SILC
7171 is compiled with older va_arg() the new code should work anyway.
7173 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7175 * Splitted core library. Core library (lib/silccore) includes
7176 now only SILC protocol specific core (and common) components.
7177 Created new utility library (lib/silcutil) that includes more
7178 generic purpose stuff. The stuff for util library was taken
7179 from the old core library. This was minor and easy split.
7181 * Created SILC Client Library (lib/silcclient) that includes
7182 implementation of the SILC client without user interface. This
7183 was major move from silc/ directory. The code has been changed
7184 so that it is transparent towards the user interface. The
7185 silc/ directory includes now the same user interface as before
7186 and it uses the new client library. Read lib/silcclient/README.
7187 Basicly, the client library performs everything else related
7188 to SILC except user interface handling. Also, configuration
7189 files are considered to be part of user interface and library
7190 does not handle them.
7192 This change also changed a lot of structures, function naming etc.
7193 Most important change was that SilcClientWindow object was
7194 renamed to SilcClientConnection in the client library. Created
7195 also new file lib/silcclient/ops.h. Also added new files
7196 silc/local_command.[ch] and silc/client_ops.[ch].
7198 All these changes were made to make it easier for user interface
7199 designers to create what ever user interface for the SILC client
7202 It is also expected that the server will be moved to lib
7203 directory as well and SILC Server Library will be created;
7204 sometimes in the future.
7206 * Removed Local commands from lib/silccore/silccommand.h as
7207 they are application specific and new client library does not
7208 handle any of those anymore.
7210 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7211 old client implementation in silc/.
7213 * Added support for callback functions in SILC_LOG_* macros.
7214 Application can now set its own callbacks that will be called
7215 instead of using the default functions that will always print
7216 the debug messages to stderr (or stdout). Also, debugging can
7217 now be disabled by setting silc_debug to FALSE and re-enabled by
7218 setting it to TRUE. Note, that logging will still work even
7219 if debugging is disabled.
7221 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7222 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7223 silc_log_reset_debug_callbacks.
7225 * To enable debugging in silc client one must give now -d
7226 option on command line.
7228 * Changed silc_schedule_init to automatically allocate task queues
7229 if they are not allocated before calling it.
7231 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7233 * Added GMP 3.1 into math library.
7235 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7237 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7238 a channel in SILC network. The packet is used by servers and
7239 routers to notify other routers that user has left a channel.
7240 This little feature was missing until now. Added the feature
7241 to protocol specification as well.
7243 Added functions: silc_server_send_remove_channel_user and
7244 silc_server_remove_channel_user into server.[ch].
7246 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7247 lib/silccore/silcpacket.h. However, they are not implemented
7250 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7252 * Fixed joining to a channel and sending channel messages
7253 between server and router. The channel message sending should
7254 now work inside a cell.
7256 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7258 * Fixed the private message sending between server and router.
7259 The private message sending should now work inside a cell.
7261 * Added silc_server_replace_id into server.[ch] to replace
7262 existing ID in the SILC network.
7264 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7265 and silc_idlist_replace_server_id into idlist.[ch] in server.
7267 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7269 * Fixed the server to server connections. Server can again now
7270 connect to router. Router to router connections probably does
7273 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7275 * Added dynamic protocol registering support. Now protocols can
7276 registered and unregistered on the fly. Patch by cras.
7278 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7280 * Added lib/contrib directory to hold routines that some platforms
7281 don't have but are needed by SILC.
7283 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7284 into lin/contrib to provide getopt() and getopt_long() for
7285 those who don't have it.
7287 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7289 * Added AWAY command to client. When away message is set and
7290 client receives a private message packet the client automatically
7291 replies to the sender with the away message.
7293 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7294 bug seemed to be the cause of recent problems when compiling
7297 * Added version detection support to SKE protocol specification
7298 and added the new changes to the SKE implementation as well.
7299 There were other minor changes in the SKE protocol as well.
7301 Many changes in lib/silcske/silcske.[ch] and in
7302 lib/silcske/payload.[ch].
7304 * Added ^U functionality, clear input line. Patch from cras.
7306 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7308 * Mainly small bugfixes on core library. Fixed some debugging
7309 logging and buffer overflow in silclog.c.
7311 * Updated config.sub and config.guess on the distribution tree.
7313 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7315 * Added command lagging support in server. Client may execute
7316 commands now only once in two seconds.
7318 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7320 * Optimized packet reception. MAC computation and checking is now
7321 also more optimized. A lot previously duplicated code is now
7322 used as generic by both client and server.
7324 * Fixed key pair generation in clientutil.c
7326 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7328 * Added into lib/silccore/silcbufutil.[ch] new function;
7329 silc_buffer_realloc.
7331 * Moved generic packet sending/encryption functions to
7332 lib/silccore/silcpacket.[ch] from client and server. Some
7333 rewriting of the functions.
7335 * Moved all generic packet reception/decryption functions to
7336 lib/silccore/silcpacket.[ch] from client and server. The
7337 packet processing is now much cleaner in both client and server.
7338 These were major changes in both client and server.
7340 * Created many common functions in server to do packet sending.
7341 Previously code were duplicated a lot, this has been removed
7344 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7346 * Rewrote major parts of the ID cache system. Don't know
7347 whether it is better now or not but at least the API is more
7350 * Major rewrite on ID cache stuff on client because of the ID
7351 cache API changes. Added idlist.c to client.
7353 * Also major rewrite on ID cache stuff on server as well.
7354 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7355 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7356 in hand, instead they are all put into the ID cache system now.
7357 All server_idlist_* routines uses ID cache now instead of
7358 traversing its own lists (those lists does not exist anymore).
7359 SilcIDList though still exists. Also, SilcXXXEntry's are
7362 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7364 * Finally made the SKE implementation compliant to the protocol
7365 specification. All mp integers are now binary encoded as
7366 opposed being HEX encoded.
7368 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7371 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7372 functions: silc_[encode/decode]_pem. Also added function
7373 silc_encode_pem_file to PEM encode with newlines ('\n') for
7376 * SILC public keys are now encoded either PEM or binary. Same
7377 option is for private keys as well. By default private keys
7378 are binary encoded and public keys PEM encoded. Silly HEX
7379 encoding were removed.
7381 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7382 function to create fingerprints.
7384 * Fixed a bug in SHA1; does not change the original data anymore.
7386 * Partly implemented INFO command on client and server side.
7387 Fixed CLEAR command. Changes to SERVER command; show current
7388 server(s) when giving command without arguments. Added
7389 VERSION command to client.
7391 * Added check to server that unregistered connections cannot
7392 execute commands (unless it is specificly allowed).
7394 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7396 * Fixed screen refresh.
7398 * Fixed channel joining bug from client. On some circumstances
7399 client tried to join to a channel it had already joined.
7401 * Added public key verification process into client's protocol.c.
7402 The client now verifies the public key from user and saves
7403 it into ~./silc/serverkeys/ directory.
7405 Added into: clientutil.[ch]: silc_client_verify_server_key.
7407 * Changed SKE protocol's silc_ske_initiator_finish function
7408 to accept callback function that verifies the received public
7409 key. Removed old silc_ske_verify_public_key function.
7411 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7413 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7414 silc_pkcs_private_key[_data]_set.
7416 * Made the password and public authentication more cleaner in
7417 server's protocol.c.
7419 * Removed historic and obsolete protocol `channel_auth' from
7420 both client and server.
7422 * Removed wrong way of sending command status messages from
7423 server to client in server's command.c. The old way violated
7424 protocol specification.
7426 Changes to silccore/silccommand.[ch]: removed
7427 silc_command_encode_status_payload -> not needed anymore,
7428 changed silc_command_encode_payload_va to accept extra
7429 argument on variable argument list. The argument type must
7430 now be provided to the function. Also, added new function:
7431 silc_command_encode_reply_payload_va which is same as
7432 normal command_encode_payload_va except command status type
7433 is provided as extra argument.
7435 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7437 * Added ~./silc directory handling. The directory includes the
7438 public and private keys for the client.
7440 Added silc_client_check_silc_dir, silc_client_create_identifier
7441 and silc_client_load_keys.
7443 * Implemented SILC protocol compliant public key. Added public
7444 and private key saving to and loading from files.
7446 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7447 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7448 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7449 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7450 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7452 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7453 silc_pkcs_load_[public/private]_key.
7455 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7457 * Added silc_server_get_route (route.[ch]) to get connection
7458 data for the fastest route for given ID.
7460 * Implemented INVITE command on client and server. The command
7461 were re-defined in the SILC Protocol Specification and the
7462 implementation now complies with the specification.
7464 * Implemented PING command on client and server.
7466 * Implemented NAMES command on client and server. The server side
7467 supports currently only normal server not router server yet.
7468 Some changes to NAMES definition in SILC protocol specification.
7470 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7472 * Implemented LEAVE command on client and server.
7474 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7475 again. This change was made to the protocol as well. Server
7476 should not violate the protocol specification anymore.
7478 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7480 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7481 was tested. SOCKS4 was not but should work anyway.
