1 Wed Apr 3 12:36:05 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added better error logging in rekey protocol. Affected file
6 * Do not check public key types in SKE during rekey. Affected
7 file lib/silcske/payload.c.
9 * Fixed the rekey protocol with PFS, which was totally broken.
10 Affected file silcd/protocol.c.
12 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
14 * Merged version 1.1.4 of zlib. Even if it not currently in use,
15 it's good not to have security holes here.
17 * Fixed a negative refcount situtuation for the config context.
18 Affected file is silcd/serverconfig.c.
20 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
22 * ROBOdoc documented lib/silcutil/silcutil.h.
24 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
26 * Changed the silc_get_username and silc_get_real_name to
27 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
29 * Fixed the Irssi SILC Client to use the silc_get_username and
30 silc_get_real_name insted of glib routines since the glib
31 routines only corrupt stack. Fixes the Irssi SILC to work in
32 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
34 * Fixed the Irssi to not use g_get_home_dir since it crashes
35 or returns garbage on cygwin and corrupts stack. Added function
36 get_home_dir to Irssi routines. Affected files are
37 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
39 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
41 * And yet again reverted back the config thing since Johnny
42 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
45 * Fixed memory leaks from config object. Affected files are
46 silcd/serverconfig.[ch].
48 * Added support for adding new connections to the server in rehash.
49 After rehash they take effect.
51 Added support for changing the maximum allowed connections in
52 rehash. The number can grow but going smaller is not supported.
54 Added function silc_server_num_sockets_by_remote to the
55 silcd/server_util.[ch].
57 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
59 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
61 * Added preliminary checking during config parsing for a valid
62 public/private key and removed further checks in the code.
63 Affected files are silcd/serverconfig.[ch], server.c.
65 * Moved functions silc_server_drop() and silc_server_daemonise()
66 from server.c to silcd.c since they are stricly related to
67 the application activity.
69 * Reverted a small part of the automatic ref/unref since
70 it caused a double unref in some situations. Affected
71 files are silcd/silcd.[ch], server.c, serverconfig.c.
73 * Added some .cvsignore files in the lib directory.
75 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
77 * Fixed silc_net_gethostbyaddr to correctly resolve by
78 address. Affected file lib/silcutil/silcnet.c.
80 * Fixed the notify relaying to client. The HMAC to be used
81 with relayed packets ws wrong and caused decryption failure
82 at the client end. Affected file is silcd/packet_receive.c.
84 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
86 * Created new branch silc_protocol_1_0_branch.
88 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
90 * Changed the silc_server_config_* routines to be SilcServer
91 independent. They are now officially application specific code
92 and not part of generic server implementation. Affected files
93 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
95 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
97 * Added automatic referencing of config context in the
98 silc_server_config_alloc, and automatic unreferencing in the
99 silc_server_config_destroy. Affected files are
100 silcd/serverconfig.[ch], silcd/silcd.c.
102 * Fixed the silc_log_quick handling in the logging routines.
103 It didn't log quickly when it was TRUE. Affected file is
104 lib/silcutil/silclog.c. Also the flush delay was set even
105 if it was 0 in config file. Affected file is
106 silcd/serverconfig.c.
108 * Added support for changing key pair of the server in rehash.
109 Affected file silcd/server.c.
111 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
113 * Fixed the TOPIC_SET notify to not cras. It changed the topic
114 too early, before getting the channel entry. Affected file
115 is silcd/packet_receive.c.
117 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
119 * Added functions silc_server_config_[ref/unref], these are used
120 to prevent that the config object is destroyed.
122 No longer directly affect global variables silc_log_quick and
123 silc_log_delay, they are first cached inside the config object
124 and then applied with silc_server_config_setlogfiles().
126 silc_server_config_set_defaults() is now internal to
127 serverconfig.c, there are no reasons to show this internal stuff
130 Affected files are silcd/serverconfig.[ch].
132 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
133 fprintf's to stderr, since some code may be executed again after
134 the server went into the background. Affected files are
137 * Added rehash support. Added function silc_server_rehash() that
138 will perform all the basic tasks of the rehashing procedure.
140 * Added command line option `-x, --hexdump'. This will enable the
141 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
142 The option `--hexdump' implies `--debug'.
144 * Fixed a bad bug in the logging APIs (silcutil library) where
145 the application would crash after calling silc_log_reset_all().
147 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
149 * Fixed the KICKED notify handling in client library to
150 correctly remove the channel and all entries from the
151 channel when I was kicked. This bug crashed the client.
153 Fixed yet another but in KICKED notify handling to remove
154 the kicked client correctly from the channel.
156 Affected file is lib/silcclient/client_notify.c.
158 * Fixed a minor bug in looking up correct client entry
159 in KICKED notify in server. Affected file is
160 silcd/packet_receive.c.
162 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
163 sources correctly to distribution. Fixes --with-gmp option.
165 * Removed the manual rehashing from ID Cache, and changed it
166 to use the SILC Hash Table's auto rehash feature. Affected
167 file is lib/silccore/silcidcache.c.
169 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
171 * Fixed a bug in the silc_client_nickname_format function that
172 handles the multiple same nickname formatting. Two clients
173 with same nickname caused problems after the first one left
174 and rejoined. It didn't format the nickname correctly.
175 Affected file is lib/silcclient/idlist.c.
177 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
179 * Don't change the topic if olod topic is same as new one.
180 Affected file is silcd/packet_receive.c.
182 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
184 * Added cross-reference support to the SILC Documentation
185 generator. All types across all HTML files are now cross-
186 referenced. Affected files util/robodoc/generator.c and
187 scripts/silcdoc/silcdoc.
189 * Added file lib/silcutil/silctypes.h to include all the
190 arithmetic type definitions and some macros. Removed
191 includes/bitmove.h and moved macros to silctypes.h.
193 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
195 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
197 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
199 * Added `type' argument to silc_id_payload_parse_id function which
200 now returns the type of the ID to the sent pointer. Affected
201 file is lib/silccore/silcid.[ch].
203 * Added check for CMODE_CHANGE notify type that mode change is
204 allowed by the sender. Affected file silcd/packet_receive.c.
206 * Added check for CUMODE_CHANGE notify type that mode change is
207 allowed by the sender. Affected file silcd/packet_receive.c.
208 Added the ID type as CUMODE_CHANGE notify type as argument
209 to the `notify' client operation. Affected files are
210 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
212 * Added function silc_client_add_server to the client library.
213 Added support for resolving also channel and server info when
214 received unknown entity in notify packet. Affected files are
215 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
217 * Added function silc_command_get_status to return the command
218 status from the command reply's argument payload. Affected files
219 are lib/silccore/silccommand.[ch].
221 * Added check for KICKED notify type that the kicking is
222 allowed by the client. Affected file silcd/packet_receive.c.
224 * Created function silc_get_input which can be used to get input
225 (echo on or off) from user on command line. Affected files are
226 lib/silcutil/silcutil.[ch].
228 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
230 * Optimized silc_server_packet_relay_to_channel function.
231 Added new function silc_channel_message_payload_encrypt which
232 can be called directly if channel message payload needs to
233 be encrypted and is already encoded (no need to call _encode
234 function). Packet relaying is now done by router without any
235 extra memory allocations. Affected files are
236 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
239 * Fixed the INVITE notify handling. It took wrong arguments
240 as invite list and invite delete. Affected file is
241 silcd/packet_receive.c.
243 * Added check for TOPIC_SET notify type that the topic change is
244 allowed by the client. Affected file silcd/packet_receive.c.
246 * Added check for INVITE notify type that inviting is allowed by
247 the client. Affected file silcd/packet_receive.c.
249 * Changed the silc_server_client_on_channel to return the
250 SilcChannelClientEntry as well. Moved the function
251 silc_server_check_cmode_rights to server_util.[ch].
252 Affected files are silcd/server_util.[ch], silcd/command.c.
254 * Added function silc_server_check_umode_rights to check whether
255 changing client's user mode is allowed. Added check for
256 UMODE_CHANGE notify type that the umode change is allowed
257 by the client. Affected files are silcd/server_util.[ch],
258 silcd/packet_receive.c and silcd/command.c.
260 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
262 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
263 ID length. It ignored that ID can be IPv6 based as well.
264 Affected file lib/silccore/silcpacket.h.
266 * Fixed the silc_id_id2str and silc_id_str2id to take the
267 IPv6 address offset's into consideration. Affecte file is
268 lib/silccore/silcid.c.
270 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
272 * Fixed the internal Unix scheduler functions to check for
273 NULL context they may receive. The affected file is
274 lib/silcutil/unix/silcunixschedule.c.
276 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
278 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
279 can specify different directory with --home command line
280 parameter. Affected files irssi/src/silc/core/client_ops.c,
283 * SILC-specific commands aren't now executed if the active server
284 isn't of SILC-type, so there won't be problems with having
285 IRC and SILC protocol support in same client. Affected files
286 irssi/src/silc/core/silc-channels.c, silc-servers.c,
289 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
291 * Improved the signal support in SILC Schedule. Added new
292 function silc_schedule_signal_call which is used by application
293 to mark a signal to be called. It is now safe to perform
294 any kind of tasks in signal callbacks since it is guaranteed
295 that the application specified signal callback is called
296 after the signal is over. Affected files are
297 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
299 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
301 * Added `name' field to SilcChannelPrivateKey to represent
302 application given name for the key. Moved also the context from
303 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
304 Added the `name' argument also to the function
305 silc_client_add_channel_private_key.
307 Added function silc_client_current_channel_private_key to set the
308 current channel private key in use.
310 Added "change" command to KEY command which can be used to change
311 the current channel private key. Bound the command also to
314 Also affected files lib/silcclient/client_channel.c,
315 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
317 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
319 * Added silc_rng_get_byte_fast function in to the
320 lib/silccrypt/silcrng.[ch].
322 * Changed the interface of silc_packet_assemble and the
323 silc_packet_send_prepare. If silc_packet_assmble is now
324 called the application does not call silc_packet_send_prepare
325 because the library will call it automatically. These
326 interfaces now also return a reference to the outgoing buffer
327 which includes the assembled packet, which the application can
328 use to encrypt the packet.
330 Affected files are lib/silccore/silcpacket.[ch],
331 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
332 silcd/packet_send.c, server_backup.c and packet_receive.c.
334 * Fixed a packet sending bug on very high load, where outgoing
335 packet queue wasn't handled correctly and packets got corrupted.
336 Affected files are lib/silcutil/*/silc*sockconn.c,
337 lib/silcclient/client.c and silcd/server.c.
339 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
341 * Added macro SILC_PACKET_DATALEN which can be used during
342 packet assembling to check whether the data to be added to
343 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
344 len is truncated until it fits it.
346 Added checks for maximum length of channel message payload and
347 private message payload also.
349 Added checks for maximum packet length in server and in
352 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
353 lib/silcclient/client.c, lib/silccore/silcchannel.c and
354 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
355 lib/silcclient/client_prvmsg.c.
357 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
359 * Added silc_server_packet_queue_purge call to the
360 silc_server_disconnect_remote to assure that all data in the
361 queue before disconnecting is sent to the network. Affected
364 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
366 * Added the deleting of server's own ID cache entry to the
367 silc_server_free function. Free also everything else that
368 has been allocated in silc_server_init. The affected file
371 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
373 * Added functions silc_parse_version_string, silc_version_to_num,
374 and silc_ske_parse_version to parse SILC protocol style version
375 strings. Affected files lib/silcutil/silcutil.[ch] and
376 lib/silcske/silcske.[ch].
378 * Added new configuration params: version_protocol, version_software
379 and version_software_vendor to specify what version the remote
380 host must at least be to be able to connect to server. The vendor
381 string can be regex matched too. Added new function
382 silc_server_connection_allowed to check maximum number of allowed
383 connections, and allowed versions for incoming connections.
384 Affected files are silcd/server.c, server_util.[ch] and
387 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
389 * Added preliminary support for signals in scheduler. The
390 signals we care about are now blocked always when the scheduler
391 is locked. This way we can synchronise the use of signal with
392 scheduler. It is guaranteed that when signal occurs the scheduler
393 is not locked, and thus new tasks can be safely added to the
396 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
397 to silc_schedule_internal_init and silc_schedule_internal_uninit.
398 Added new platform specific routines
399 silc_schedule_internal_signals_[un]block and
400 silc_schedule_internal_signal_[un]register.
402 Added new functions to SILC Schedule API:
403 silc_schedule_signal_[un]register. Each signal that application
404 is going to use should be registered to the scheduler.
406 Affected files are lib/silcutil/silcschedule.[ch],
407 lib/silcutil/*/silc*schedule.c.
409 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
411 * Check for unauthenticated client and server in the
412 silc_server_new_client and silc_server_new_server functions.
413 Affected file silcd/packet_receive.c.
415 * Added function silc_string_is_ascii to check whether given
416 string is 7-bit ASCII string. Affected files are
417 lib/silcutil/silcutil.[ch].
419 * Added function silc_id_is_valid_server_id into the
420 silcd/serverid.c and added checking for valid Server ID's in
421 silc_server_new_server. The Server ID must always be based
422 on the server's public IP address.
424 * Added logging of DISCONNECT packet message in the server.
425 Affected file silcd/server.c.
427 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
429 * Changed all library interfaces that use Global RNG to also
430 accept SilcRng as argument. Affected files are
431 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
432 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
433 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
434 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
437 * Added function silc_pkcs_generate_key to the
438 lib/silccrypt/silcpkcs.[ch] for applications so that they
439 don't need to do pkcs->pkcs->init calls anymore.
441 * Remove SilcSocketConnection from the SFTP API since it really
442 wasn't needed there. The application has the information
443 saved in its contexts anyway and the SFTP layer doesn't need
444 know about it. Affected files lib/silcsft/silcsftp.h and
445 lib/silcsftp/sftp_[server/client].c.
447 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
448 The SilcSimContext is not SilcSim.
450 * Fixed possible buffer overflows in silc_id_render in the
451 lib/silcutil/silcutil.c.
453 * On EPOC the global crypto module lists are not used at all
454 in the crypto library. Added support for using the constant
455 algorithm list on EPOC. Affected files are
456 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
459 * Fixed the handling of third parameter of KICKED notify, since
460 it was mistakenly updated to SILC Protocol 1.0 even though it
461 is to be included in 1.1. Since it is not in 1.0 it is not
462 mandatory, and this fix now handles it only if it is provided,
463 and it is not error if it is not provided. Affected file
464 lib/silcclient/client_notify.c.
466 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
468 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
469 client. Affected file irssi/src/silc/core/client_ops.c.
471 * Merged with Irssi 0.8.4 from irssi.org CVS.
473 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
475 * Check for valid socket connection in client entries before
476 sending any messages. Fixes a crash, but doesn't fix some
477 other underlaying bug that is lurking there. Affected
478 file silcd/packet_send.c.
480 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
482 * $usermode, $cumode and $cumode_space expandos shouldn't do
483 anything with non-SILC server records. Affected file
484 irssi/src/silc/core/silc-expandos.c
486 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
488 * Fixed the silc_net_check_[host/local]_by_sock to support
489 IPv6 bound sockets as well. Now they can return IPv6 addresses
490 as well. Affected file lib/silcutil/silcnet.c.
492 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
493 Affected lib/silcutil/unix/silcunixnet.c.
495 * Fixed ID rendering (at least on some platforms, not NetBSD)
496 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
498 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
500 * Added silc_hash_public_key and silc_hash_public_key_compare
501 functions to be used with SilcHashTable. They can be used to
502 hash public keys and compare public keys in hash table. Affected
503 file lib/silcutil/silcutil.[ch].
505 * Added support for specifying multiple public keys for Client
506 connection section in server configuration file. This makes it
507 possible to accept multiple public keys from same host, or to
508 make a section that accepts any incoming host, and have the
509 accepted public keys listed in the section.
511 Added functions silc_sever_[find/get]_public_key, added the
512 support for this actually to all connection sections but only
513 the Client section is currently allowed to specify multiple
516 Affected files are silcd/server.c, server_internal.h,
517 command.c, protocol.c, server_util.[ch], packet_receive.c.
519 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
521 * Merged Irssi 0.8.2 from irssi.org CVS.
523 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
525 * If silc_debug is TRUE, also output standard logging messages
526 to stderr with the debug output.
528 Made silc_log_reset_all() flushing all channels before returning.
529 Also fixed some documentation typos.
531 Affected files are lib/silcutil/silclog.[ch].

683 Affected file lib/silcclient/client.c.
685 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
687 * ROBOdoc documented the lib/silcske/silcske.h, and improved
688 the SKE interface a bit.
690 * Fixed padding problem in PKCS#1. The padding was not actually
691 random since the random number generator was used incorrectly.
692 This security bug affects only when encrypting with PKCS#1, and
693 it is not currently used at all in SILC. SILC only use signing
694 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

775 algorithm parts and created new file silcalgs.conf, that
776 is now included from the example_silcd.conf.in.
778 * Optimized the silc_server_connect_to_router_second to take
779 the connection configuration object from the SilcServerConnection
780 object instead of finding it during the connecting phase.
781 Added the configuration object to SilcServerConnection struct.
782 Affected files silcd/server_internal.h, server.c.

810 public key is set. If not set, public key is preferred.
811 This has effect only when being initiator (responder will try
814 Added support for authentication with passphrase and public key
815 at the same time. The passphrase is tried first always since
816 it is faster to check.
818 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
820 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

866 * Fixed the file transfer's key agreement payload to include
867 zero port also if the hostname is NULL because it could not
870 Call file transfer monitor callback now also if error occurs
871 during key agreement protocol.
873 Changed the silc_client_file_send interface to return the
874 SilcClientFileError instead of session id. The session ID
875 is returned into pointer provided as argument.

892 file lib/silcutil/silclog.c.
894 * Fixed the channel message payload decryption in the function
895 silc_channel_message_payload_decrypt to not modify the original
896 buffer before it is verified that the message decrypted
897 correctly. Otherwise, next time it is called with correct
898 channel key it won't encrypt since the payload is corrupted.
899 Affected file lib/silccore/silcchannel.c.
901 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

914 the table with foreach callback. The current entry may
915 become invalid in the callback but it was referenced after
916 the callback returned.
918 Do not allow auto rehashing of hash table during the
919 silc_hash_table_foreach operation, for same reasons as it is
920 not allowed for SilcHashTableList. Affected files are
921 lib/silcutil/silchashtable.[ch].
923 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

944 users list to SilcHashTable. The affected files are
945 lib/silcclient/idlist.[ch].
947 * Fixed a bug in hash table tarversing. While the hash table
948 is traversed with SilcHashTableList the table must not be
949 rehashed. It is now guaranteed that auto rehashable tables
950 are not rehashed while tarversing the list. Also defined that
951 silc_hash_table_rehash must not be called while tarversing
952 the table. Added function silc_hash_table_list_reset that must
953 be called after the tarversing is over. The affected files are
954 lib/silcutil/silchashtable.[ch].
956 * Changed all hash table traversing to call the new
957 silc_hash_table_list_reset in server and in client library.
959 * Added function silc_client_on_channel to return the
960 SilcChannelUser entry if the specified client entry is joined

975 * When sending JOIN command to router for processing the
976 sender's old command identifier was not saved back to the
977 sender's command context, fixed now. The affected file is
980 * Create the key in JOIN command of the router did not return
981 the channel key, added check for this. Affected file is
984 * Fixed a channel ID update bug in JOIN command reply. Do
985 not directly upgrade the ID but call the function
986 silc_idlist_replace_channel_id if the ID was changed.
987 Affected file silcd/command_reply.c.
989 * Fixed memory leaks from command calling if it would fail.
990 Affected file silcd/command.c.

1017 functions. Affected file silcd/server.c.
1019 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1020 which ID was changed. This way the router will send the
1021 user list for the channel again, and server won't be in
1022 desync in some rare circumstances. Affected file is
1023 silcd/packet_receive.c.
1025 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1080 * Fixed some double frees from client library commands.
1081 Affected file is lib/silcclient/command.c.
1083 * Fixed CUMODE command in server to assure that no one can
1084 change founder's mode than the founder itself, there was a
1085 little bug. Affected file silcd/command.c.
1087 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1089 * Removed the SilcClientCommandDestructor from the client
1090 libary, it is not needed anymore. Affected files are
1091 lib/silcclient/silcapi.h, command[_reply].[ch],
1092 client_notify, idlist.c.
1094 * Fixed GETKEY command to first resolve client, and then
1095 resolve the server only if the client was not found, instead
1096 of resolving both at the same time. Affected file is
1097 lib/silcclient/command.c.
1099 * Added silc_client_start_key_exchange_cb and lookup the
1100 remote hostname and IP address before starting the key
1101 exchange with server. The affected file is
1102 lib/silcclient/client.c.
1104 * The server's public key is now saved using the IP address
1105 of the server and not the servername for the filename.
1106 The hostname public key filename is checked as an fall back
1107 method if the IP address based filename is not found.
1109 Fixed the GETKEY command to save the fetched server key
1110 in correct filename.
1112 Print the remote server's hostname now when new key is
1113 received during connection process. Affected file is
1114 irssi/src/silc/core/client_ops.c.
1116 * Return always our own public key to the client if it asks
1117 for it with GETKEY command. Affected file silcd/command.c.
1119 * Removed the use_auto_addr variable from default config
1120 file since it was in wrong section. Affected file is
1123 * Fixed TOPIC_CHANGE notification to not route it when it
1124 was sent using silc_server_send_notify_to_channel function.
1125 Affected file silcd/command.c.
1127 * Fixed silc_server_send_notify_kicked to send the kicker's
1128 Client ID also, it was missing. Affected files are
1129 silcd/command.c, silcd/packet_send.[ch].
1131 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1133 * Do not save client history information in SERVER_SIGNOFF.
1134 Fixes the bug in normal server that it does not detect
1135 the client becoming valid after the server becomes back
1136 online. Affected file silcd/server_util.c.
1138 * Added `sock_error' field into the SilcSocketConnection
1139 context. When error occurs during socket operation (read
1140 or write) the error is saved. Added also new function
1141 silc_socket_get_error to return human readable socket error
1142 message. Affected files are lib/silcutil/silcsockconn.[ch],
1143 lib/silcutil/unix/silcunixsockconn.c, and
1144 lib/silcutil/win32/silcwin32sockconn.c.
1146 * The server now prints the socket error message in the
1147 signoff for client. Affected file silcd/server.c.
1149 * Fixed the `created' channel information sending from router
1150 to server in JOIN command. Checks now whether the channel
1151 really was created or not and set it according that.
1153 Fixed the JOIN command to use the client entry's current
1154 ID during the joining procedure instead of the one it sent
1155 in the command (it is checked though), since it can change
1156 between the packet processing and command processing, and
1157 would just case unnecessary pain in the client end. Affected
1158 file silcd/command.c.
1160 * Fixed a channel key payload sending to use correct channel
1161 ID when the server was forced to change the channel's ID by
1162 router. Router sent the key payload with the old Channel ID.
1163 Affected file silcd/packet_receive.c.
1165 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1167 * Call silc_server_save_channel_key only if the key payload
1168 was provided in the JOIN command's command reply. Affected
1169 file silcd/command_reply.c.
1171 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1173 * Fixed silc_mp_sizeinbase to return the value correctly with
1174 MPI. Affected file lib/silcmath/mp_mpi.c.
1176 * Fixed the stop_server signal to correctly stop the scheduler
1177 and gracefully stop the server when SIGTERM or SIGINT signals
1178 are received. Affected file silcd/silcd.c.
1180 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1182 * Simple handling of TERM and HUP signals. Also added some log
1183 flushing call around. Affected file is
1186 * Fixed small bugs in silclog.c. Now buffering output will take
1187 effect after 10 seconds since startup: This will ensure that
1188 no important startup messages are lost. Also output redirection
1189 will preserve original format ([Date] [Type] message).
1190 Affected file is lib/silcutil/silclog.c.
1192 * Added two options to the config file, in the logging section:
1193 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1194 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1196 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1198 * Do not print the warning about log files not being initialized
1199 more than once to avoid excess logging. Affected file is
1200 lib/silcutil/silclog.c.
1202 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1203 the SIM copying in make install in Makefile.am.pre.
1205 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1207 * Rewritten silclog APIs. Globally interesting changes follows:
1208 silc_log_set_files() changed to silc_log_set_file().
1209 silc_log_set_callbacks() changed to silc_log_set_callback().
1210 ROBOdoc documented silclog header file.
1211 SilcLogCb now returns bool to wether inihibit the default
1212 handler or not (to keep the old behaviour return always TRUE).
1213 The new APIs should also fix the problem of the
1214 silcd_error.log file that was written in the current directory.
1217 Log files streams will remain opened after silc_log_set_file()
1218 call, means less CPU usage notably on high traffic servers.
1219 File streams are now full buffered, and flushed to the disk
1220 every 5 minutes, lesses HD activity and CPU usage.
1221 Messages can be redirected, allowing admins to configure
1222 one single logfile for all server messages.
1223 the silc_log_quick global variable to activate fast-logging.
1224 Affected files lib/silcutil/silclog.[ch]
1226 * Changed some code to conform new silclog APIs. Affected
1227 files are doc/example_silcd.conf.in, silcd/server.c
1228 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1231 * Fixed a memory leak that could occur in some situations.
1232 Affected file silcd/serverconfig.c.
1234 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1236 * Added the silc_client_del_client to remove the client from
1237 all channels as well. Affected file lib/silcclient/idlist.c.
1239 * Fixed the client library to correctly remove the client
1240 from all channels when the client entry is being destroyed.
1241 Affected file lib/silcclient/client_notify.c, command.c.
1243 * Added auto-nicking support to the client library. If the
1244 applicatio now sets client->nickname it will be sent to the
1245 server after connecting by the library. This way for example
1246 SILCNICK (or IRCNICK) environment variables will have effect
1247 and always change the nickname automatically to whatever
1248 it is wanted. Affected file lib/silcclient/client.[ch].
1250 * Renamed silc_server_command_bad_chars to the
1251 silc_server_name_bad_chars and moved it to the
1252 silcd/server_util.[ch]. Added also new function
1253 silc_server_name_modify_bad to return nickname that
1254 includes bad characters as new nickname without those
1255 bad characters. This check and modify is now used in
1256 silc_server_new_client when the username is initially set
1257 as nickname, so it must be checked to be valid nickname.
1258 Affected file silcd/packet_receive.c.
1260 * The nickname length is now taken from the packet for real
1261 and not trusted to strlen() since it clearly can return
1262 wrong length for nickname including bad characters. This
1263 also applies to channel names. Affected file silcd/command.c.
1265 * Removed the lib/silcsilm/modules directory. Modules are now
1266 compiled into the lib/silcsim. Fixed the copying of the
1267 modules to follow symbolic links in Makefile.am.pre.
1269 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1271 * Fixed silc_string_regexify list creation. Fixes bugs with
1272 BAN and INVITE commands in server. The affected file is
1273 lib/silcutil/unix/silcunixutil.c.
1275 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Removed the command destructor entirely from the server's
1278 command and command reply routines. It is not needed, and
1279 its usage was buggy and caused crashes. Affected files are
1280 silcd/command[_reply].[ch].
1282 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1284 * Cancel protocol and NULL sock->protocol if timeout
1285 occurred during protocol. Affected file silcd/server.c.
1287 * Cancel protocol timeouts always before calling the final
1288 callback, to assure that after final callback is called
1289 no other state will be called for the protocol anymore.
1290 Affected file silcd/protocol.c.
1292 * Print error log if incoming connection configuration could
1293 not be found. Affected file silcd/server.c.
1295 * Fixed JOIN command to correctly save the founder mode
1296 to the client on normal SILC server, when the channel
1297 was created by the router. Affected file silcd/command.c.
1299 * Fixed LIST command (hopefully) to send correct reply
1300 packets. Affected file silcd/command.c.
1302 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * The silc_packet_receive_process now returns FALSE if the
1305 read data was invalid packet, and TRUE if it was ok.
1307 The server now checks that if unauthenticated connection
1308 sends data and its processing fails the server will close
1309 the connection since it could be a malicious flooder.
1311 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1313 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1315 * Make sure the warning about error opening a log file is
1316 printed only once and not everytime it fails (produces
1317 too much useless log). Affected file lib/silcutil/silclog.c.
1319 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1321 * Made the silc_server_daemonise() function more readable.
1322 Affected file silcd/server.c.
1324 * Pid file is now optional, the user may comment it out from
1325 the config file. Removed define SILC_SERVER_PID_FILE, we
1326 don't need a default any longer. Affected file
1327 configure.in.pre, lib/Makefile.am.pre.
1329 * Make some use of the pid file. The server now dies at startup
1330 if it detects a valid pid file on his path. The server would
1331 die anyway in this circumstance, because of the bind() failure.
1332 Affected file silcd/silcd.c.
1334 * No longer compiling lib/dotconf.
1336 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1338 * Fixed JOIN command parsing not to crash. Affected file
1339 lib/silcclient/command.c.
1341 * Fied the NICK_CHANGE notify to add the new client entry
1342 even it is resolved. This removes an <[unknown]> nick
1343 thingy bug in the client. Affected file is
1344 lib/silcclient/client_notify.c.
1346 * Do not try to allocate 0 bytes (efence does not like it)
1347 in lib/silccore/silccomand.c when encoding payload.
1349 * Do not take IRCNICK as nickname in Irssi SILC client since
1350 it is not possible to set nickname before hand connecting
1351 the server (TODO has an entry about adding auto-nicking
1354 * Changed the silc_server_command_pending to check whether
1355 there already exists an pending entry with the specified
1356 command, command identifier and pending callback. This is
1357 to fix IDENTIFY and WHOIS related crashes that may register
1358 multiple pending commands with same identifier. Affected
1359 file silcd/command.c.
1361 * Fixed the server to reconnect to the router even if it
1362 was already reconnecting and EOF was received. This to
1363 fix a possibility that the server wouldn't ever try to
1364 auto-reconnect to the router. Affected file silcd/server.c.
1366 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * Fixed the server's password authentication to use the
1369 length of the locally saved password, and not the one
1370 sent in the packet. Affected file silcd/protocol.c.
1372 * Fixed same password authentication problem in the
1373 Authentication Payload handling routines in
1374 lib/silccore/silcauth.c.
1376 * Yet another password authentication problem fixed with
1377 channel password handling in silcd/command.c.
1379 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * If first character of string in silc_parse_userfqdn is '@'
1382 then do not parse it. Affected file is
1383 lib/silcutil/silcutil.c.
1385 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Fixed minor bug in IDENTIFY command reply sending, which
1388 caused various weird problems during JOIN when it was
1389 resolving names for users. Affected file silcd/command.c.
1391 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * Fixed the IDENTIFY command reply sending to chech better valid
1394 clients. It was possible to send incomplete list of replies.
1395 Affected file silcd/command.c.
1397 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Added silc_client_command[s]_[un]register functions now to
1400 dynamically register the commands in client library. Removed
1401 the static table of commands. This allows the client library
1402 to call commands without causing the application to know about
1403 what commands library has called.
1405 Removed the INFO command reply kludge to detect when the command
1406 was called by library. Now library use its own command reply
1407 function for INFO command.
1409 Added function silc_client_command_call to call a command.
1410 Application can use it to call command, not access the structure
1413 Now all commands that are sent by the client library (not
1414 explicitly sent by application) use own command reply functions.
1416 Affected files around lib/silcclient/ and in
1417 irssi/src/silc/core/.
1419 * Fixed the WHOIS command reply sending to chech better valid
1420 clients. It was possible to send incomplete list of replies.
1422 Fixed the WHOIS and IDENTIFY to send the request to router
1423 if normal server did not do it and did not find any results.
1425 Affected file silcd/command.c.
1427 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1429 * Moved the internal data from SilcClient context into its
1430 own file, not accesible to application. Affected files
1431 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1432 and other files in client library.
1434 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1436 * Added doc/examples installation target in Makefile.am.pre.
1439 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1441 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1442 commands the found client entry will be removed from the
1443 cache, after notifying application about the error. Affected
1444 file lib/silcclient/command_reply.c.
1446 * Changed the /MSG to check for exact nickname user gave, and
1447 not let `nick' match `nick@host' if it is only one found. Now,
1448 user must type the exact nickname (like nick@host2) even if
1449 there are no more than one same nicks found. This is to avoid
1450 a possibility of sending nickname to wrong nickname since
1451 `nick' could match `nick@host'. Affected file is
1452 irssi/src/core/silc-servers.c.
1454 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1456 * Do not print "you are now server operator" or similar when
1457 giving /away command. Affected files are
1458 irssi/src/silc/core/client_ops.c, silc-servers.h.
1460 * Made the silc_server_command_pending_error_check to send
1461 the same command reply payload it received back to the
1462 original sender of the command. This way all arguments
1463 that was received by the server will be received by the
1464 client too. Affected file silcd/command.c.
1466 * Added the silc_idcache_add to return the created cache entry
1467 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1469 * Add global clients to expire if they are not on any channel.
1470 This is because normal server will never know if they signoff
1471 if they are not on any channel. The cache expiry will take
1472 case of these entries. This is done by normal servers only.
1473 The affected files are silcd/command_reply.c,
1474 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1476 * If server receives invalid ID notification for WHOIS or
1477 IDENTIFY and the ID exists in the lists, it is removed.
1478 Affected file silcd/command_reply.c.
1480 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1481 in client then client entry that it matches is searched and
1482 the nickname is printed on the screen for user. Affected
1483 file irssi/src/silc/core/client_ops.c.
1485 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1487 * Use cache entry expire time in the LIST command reply to
1488 purge old entries from the cache after the LIST command
1489 reply has been received. This way we don't have non-existent
1490 entries in the cache for too long. Affected file is
1491 silcd/command_reply.c.
1493 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1495 * If we are normal server, and we've not resolved client info
1496 in WHOIS or IDENTIFY from router, and it is global client,
1497 we'll check whether it is on some channel. If it is not
1498 then we cannot be sure about its validity and will resolve it
1499 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1500 file silcd/command.c.
1502 * Search channel by name (if possible) rather than by ID
1503 in IDENTIFY command's command reply. Affected file is
1504 silcd/command_reply.c.
1506 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1508 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1509 Updated specs and implemented it. Affected file silcd/command.c,
1510 silcd/packet_send.c and silcd/packet_receive.c.
1512 * Implemented the <founder auth> payload handling in the JOIN
1513 command. If provided all conditions for channel joining
1514 except requirement to provide correct passphrase can be
1515 overrided by the channel founder. Updated the protocol specs.
1516 Affected file silcd/command.c.
1518 Added support for founder auth in JOIN command in client
1519 library. Fixed the parsing of the JOIN command now to support
1520 all options as they should be. The affected file is
1521 lib/silcclient/command.c.
1523 * Optimized the WHOIS and IDENTIFY commands to send the request
1524 to router only if it includes nicknames or other names. If
1525 they include only IDs then check the local cache first before
1526 routing. Affected file is silcd/command.c.
1528 * Added channels topic announcements. Affected file is
1529 silcd/packet_receive.c and silcd/server.c.
1531 * Fixed the silc_server_send_notify_topic_set to really destine
1532 the packet to channel. Affected file silcd/packet_send.c.
1534 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1535 library. Affected file lib/silcclient/client_notify.c.
1537 * Added UMODE announcements. Affected file silcd/server.c.
1539 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Memory leak fixes in:
1543 lib/silcutil/silcsockconn.c
1544 lib/silcske/silcske.c
1545 lib/silcske/groups.c
1547 lib/silccrypt/silcpkcs.c
1548 lib/silccore/silccommand.c
1549 lib/silccore/silcidcache.c
1554 * ROBOdoc documented the lib/silcske/groups.h file and a
1555 bit changed the interface for better.
1557 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1559 * Update the client entry context in the ID cache after
1560 nick change. Affected file lib/silcclient/command.c.
1561 Fixes the CUMODE command when regaining founder privileges,
1562 and a little WHOIS problem.
1564 * Fixed silc_net_gethostbyname to correctly call the
1565 inet_ntop. Affected file lib/silcutil/silcnet.c.
1567 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1569 * Added IPv6 support checking to the configure.in.pre, added
1570 also --enable-ipv6 option to override the check. Affected
1571 file configure.in.pre.
1573 * The silc_thread_create now calls the start function
1574 directly if threads support is not compiled in. Removes
1575 ugly #ifdef's from generic code. Affected files are
1576 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1578 * Added silc_net_gethostby[name/addr]_async to asynchronously
1579 resolve. Affected files are lib/silcutil/silcnet.[ch].
1581 * Added support for rendering IPv6 based server, client and
1582 channel IDs. Affected file lib/silcutil/silcutil.c.
1584 * Added support for creating IPv6 based server IDs. Affected
1585 file is silcd/serverid.c.
1587 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1589 * Added silc_net_gethostby[addr/name] into the
1590 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1591 routines. Added silc_net_is_ip[4/6]. Affected file is
1592 lib/silcutil/unix/silcunixnet.c. All routines that take
1593 address as argument now supports both IPv4 and IPv6 addresses.
1595 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1597 * Fixed LIST command reply sending in server. Affected file
1600 * Server now sends the kicker's client ID in the KICK notify
1601 to the kicked client. Affected file silcd/command.c.
1603 * The client library now parses the kickers client ID and
1604 UI displays it. Affected files lib/silcclient/client_notify.c
1605 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1607 * Made all payload parsing function prototypes consistent.
1608 They all take now const unsigned char * and uint32 pair as
1609 the payload data instead of SilcBuffer. Changes all around
1610 the source tree. Other unsigned char* -> const unsigned char*
1611 changes around the tree as well.
1613 * Optimized SFTP client and server packet sending not to
1614 allocate new buffer for each packet but to recycle the
1615 first allocated buffer. Affected files are
1616 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1618 * Optimized the SFTP client to use SilcList instead of
1619 SilcDList for requests, because it is faster. Affected file
1620 is lib/silcsftp/sftp_client.c.
1622 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1623 into lib/silccore/silcid.[ch].
1625 Renamed silcpayload.[ch] into silcargument.[ch].
1627 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1629 * If client entry is deleted with active key agreement
1630 session, abort the session.
1632 The silc_client_abort_key_agreement now calls the completion
1633 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1635 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1638 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * Don't use __restrict in older GCC's. Affected file is
1641 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1643 * silc_net_localhost now attempts to reverse lookup the
1644 IP/hostname. Affected file lib/silcutil/silcnet.c.
1646 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1647 command. It can be used to gain founder privileges at
1648 the same time when joining the channel.
1650 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1651 kicker's client ID as well. Updated protocol specs.
1653 Defined that the server must send SILC_COMMAND_IDENTIFY
1654 command reply with error status to client who sent
1655 private message with invalid client ID.
1657 Updated the protocol specification.
1659 * Added silc_server_send_command_reply to send any
1660 command reply. Affected file silcd/packet_send.[ch].
1662 * Added silc_id_payload_encode_data to encode ID payload
1663 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1665 * The server now send IDENTIFY command reply with error
1666 status if client ID in private message is invalid. Affected
1667 file silcd/packet_receive.c.
1669 * Save the server key file with server's IP address in
1670 the filename instead of hostname. The affected file is
1671 irssi/src/silc/core/client_ops.c.
1673 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1675 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1678 * Added libtool support for compiling shared objects in
1679 lib/silcsim. Affected file configure.in.pre and
1680 lib/silcsim/Makefile.am. Original patch by cras.
1682 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1684 * Pid file configuration, and server's config file fixes
1685 patch by toma. Updated CREDITS file.
1687 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Fixed silc_client_channel_message to not try to decrypt
1690 the message twice if it resolved the destination client
1691 information. This could cause of dropping one channel
1692 message. Affected file lib/silcclient/client_channel.c.
1694 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1696 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1697 lib/silcclient/client.c. This function is used when the SILC
1698 Client is run under some other scheduler, or event loop or
1699 main loop. On GUI applications, for example this may be
1700 desired to used to run the client under the GUI application's
1701 main loop. Typically the GUI application would register an
1702 idle task that calls this function multiple times in a second
1703 to quickly process the SILC specific data.
1705 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1707 * Fixed silc_server_drop() for dropping the supplementary
1708 groups as well, this could cause a security hole on some
1711 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1713 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1716 * Write PID file after dropping privileges. Added -F option
1717 to run server on foreground. A patch by debolaz.
1718 Affected files silcd/server.c, silcd/silcd.c.
1720 * Fixed MOTD to return the MOTD file server name. Affected
1721 file silcd/command.c.
1723 * Added INFO command reply handling to the Irssi SILC Client.
1724 Affected file irssi/src/silc/core/client_ops.c.
1726 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1728 * Fixed the silc_idcache_list_* routines to really support
1729 the dynamic list. Fixes a crash. Affected file is
1730 lib/silccore/silcidcache.c.
1732 * Fixed the LIST command reply to really call LIST command's
1733 pending callbacks. Affected file silcd/command_reply.c.
1735 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1737 * Update conn->local_entry->nickname after giving NICK
1738 command. Affected file lib/silcclient/command.c.
1740 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1742 * Added the [pid] option to the silcd configuration file
1744 Affected files: serverconfig.[ch] and silcd.c
1746 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1748 * Save fingerprint in WHOIS command reply in server.
1749 Affected file silcd/command_reply.c.
1751 * Fixed NICK commands pending callback registration.
1752 Affected file lib/silcclient/command.c.
1754 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1756 * Use ++server->cmd_ident when sending commands in server,
1757 instead of random number. Affected file silcd/command.c.
1759 * Fixed GETKEY command reply to call actually GETKEY pending
1760 command callbacks. Affected file silcd/command_reply.c.
1762 * A bit stricter check for nicknames. Check for same nickname
1763 in NICK command also. Affected file silcd/command.c.
1765 * Do not call INFO command everytime client ID changes, only
1766 during first connecting. Affected file lib/silcclient/client.c.
1768 * Set the new nickname only after successful command reply for
1769 NICK command is returned by server. Affected file
1770 lib/silcclient/command.c.
1772 * Remove nicknames from nicklist during server_signoff notify.
1773 Should fix /NAMES bit more. The affected file is
1774 irssi/src/silc/core/silc-channels.c.
1776 * Added `fingerprint' field to the SilcIDListData in the
1777 silcd/idlist.h to hold the fingerprint of the client's
1780 Send the fingerprint of the client's public key in WHOIS
1783 Affected files silcd/command.c, and silcd/idlist.[ch].
1785 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1786 create fingerprint from given data.
1788 * Show the fingerprint of the client's public key in WHOIS.
1789 Affected files irssi/src/module-formats.[ch] and
1790 irssi/src/silc/core/client_ops.c.
1792 * Format the multiple same nicknames also during JOIN and
1793 NICK_CHANGE notifys. Affected file is
1794 lib/silcclient/client_notify.c.
1796 * Do not print error on screen for invalid private message
1797 payload since it can come if someone is sending private
1798 messages with wrong key. Affected file
1799 lib/silccore/silcprivate.c.
1801 * Fixed multiple concurrent /PING crash. Affected file
1802 lib/silcclient/command.c.
1804 * Changed the wrong ID encoding. All IP addresses must be
1805 in MSB first order in encoded format. They were encoded
1806 wrong and was in LSB format. Affected files are
1807 silcd/serverid.c, lib/silcutil/silcutil.c.
1809 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1811 * Call the `connect' client operation through the scheduler
1812 in case of error. Affected file lib/silcclient/client.c.
1814 * Call the `failure' client operation even if the error
1815 occurred locally during a protocol. Affected file is
1816 lib/silcclient/protocol.c.
1818 * Added support of sending LIST command to router from normal
1819 server. This way normal server can get list of all channels
1820 in the network too. Fixed the channel list sending in the
1821 server too. Affected files are silcd/command.c, and
1822 silcd/command_reply.[ch].
1824 * Added silc_server_update_channels_by_server and
1825 silc_server_remove_channels_by_server. They are used during
1826 disconnection of primary router and in backup router protocol.
1827 Affected file silcd/server_util.[ch], silcd/server.c and
1828 silcd/server_backup.c.
1830 * Fixed channel adding to global list in IDENTIFY command
1831 reply in server. Affected file silcd/command_reply.c.
1833 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1835 * If the incoming packet type is REKEY or REKEY_DONE process
1836 that packet always synchronously. Fixes yet another MAC
1837 failed error on slow (dialup) connections. Affected file
1838 lib/silcclient/client.c and silcd/server.c.
1840 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1842 * Call check_version SKE callback for initiator too. Affected
1843 file lib/silcske/silcske.c.
1845 * Implemented fix for security hole found in the SKE that was
1846 fixed in the specification few days back; the initiator's
1847 public key is now added to the HASH value computation.
1848 Added backwards support for the old way of doing it too, for
1849 old clients and old servers. Affected file is
1850 lib/silcske/silcske.c.
1852 * Enabled mutual authentication by default in SKE. If initiator
1853 is not providing mutual authentication the responder will
1854 force it. This will provide the proof of posession of the
1855 private key for responder. The affected files are
1856 lib/silcclient/protocol.c and silcd/protocol.c.
1858 * Do not cache anymore the server's public key during SKE.
1859 We do mutual authentication so the proof of posession of
1860 private key is done, and if the server is authenticated in
1861 conn auth protocol with public key we must have the public
1862 key already. Affected file silcd/protocol.c.
1864 * Added new global debug variable: silc_debug_hexdump. If
1865 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1866 file lib/silcutil/silclog.[ch].
1868 * Fixed compilation warning due to char * -> const char *.
1869 Affected files lib/silcutil/silcnet.h, and
1870 lib/silccore/silcauth.[ch].
1872 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Fixed CMODE command when new channel key was created. If
1875 the creation failed the old key was removed. Next time giving
1876 same command would crash the server since the old key was
1877 freed already. Affected file silcd/command.c.
1879 * Fixed the silc_server_announce_get_channels to not crash
1880 on reconnect. Affected file silcd/server.c.
1882 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1884 * Added silc_log_set_debug_string function to set a regex
1885 string to match for debug output. Only the function names,
1886 or filenames matching the given debug string is actually
1887 printed. This way it is possible to filter out those debug
1888 strings that user is not interested in.
1890 Fixed a bug in silc_string_regexify.
1892 Affected files lib/silcutil/silclog.[ch], and
1893 lib/silcutil/unix/silcunixutil.c.
1895 * Changed the -d options in both server and Irssi SILC client
1896 to take the debug string as argument. Affected files
1897 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1899 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1901 * Added silc_hash_babbleprint to create a Bubble Babble
1902 Encoded fingerprint. The encoding is developed by Antti
1903 Huima (draft-huima-babble-01.txt), and it creates human
1904 readable strings out of binary data. Affected file
1905 lib/silccrypt/silchash.[ch].
1907 * Print the babble print now in addition of fingerprint as well
1908 in Irssi SILC client. Affected files are
1909 irssi/src/fe-common/silc/module-formats.[ch],
1910 irssi/src/fe-common/silc/core/client_ops.c.
1912 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1914 * Fixed a security problem found in SKE. The initiator's
1915 public key too is now added to the HASH hash value creation
1916 which is signed by the responder to create the SIGN value.
1917 This will prevent anyone in the middle to lie to the responder
1918 about the initiator's public key. If this is done now, the
1919 man in the middle will get caught. Updated the protocol
1922 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Better installation directory handling. Configure module
1925 paths and other paths automatically to example_silc* files
1926 in doc/. A patch by toma.
1928 * Fixed compiler warning from MPI library, and from SILC RNG.
1931 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1932 It can be configured with ./configure. A patch by toma.
1934 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * Find correct make to use in prepare-clean. A patch by
1937 toma. Affected file prepare-clean.
1939 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1941 * Added irssi variables use_auto_addr, auto_bind_ip,
1942 auto_bind_port and auto_public_ip.
1944 * Changed the interface for silc_client_send_key_agreement
1945 in lib/silcclient/silcapi.h
1949 irssi/src/silc/core/silc-core.c
1951 lib/silcclient/silcapi.h
1952 irssi/src/silc/core/silc-channels.c
1953 lib/silcclient/client_keyagr.c
1956 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1958 * Added silc_pkcs_public_key_compare to compare two
1959 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1961 * Check that the client who set the founder mode on the
1962 channel is the same client that is giving the founder
1963 mode to itself. It is done by comparing the saved public
1964 key (it is saved even in the authentication is passphrase).
1965 Affected file silcd/command.c.
1967 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Do not process packet for disconnected socket connection.
1970 Affected file lib/silccore/silcpacket.c.
1972 * Process the DISCONNECT packet through scheduler in the
1973 client library. Affected file lib/silcclient/client.c.
1975 * Fixed the silc_client_packet_parse to not to increase
1976 the packet sequence number if the conn->sock and the
1977 current socket connection is not same. This can happen
1978 for example during key agreement when the conn includes
1979 multiple socket connections (listeners). Affected file
1980 lib/silcclient/client.c.
1982 * The sender of the file transfer request now provides also
1983 the pointer (listener) for the key exchange protocol. If
1984 the listener cannot be created then it sends empty key
1985 agreement and lets the receiver provide the listener.
1987 Added `local_ip' and `local_port' arguments to the
1988 silc_client_file_send. If they are provided they are used,
1989 if not then it will attempt to find local IP address, if
1990 not found or bind fails then the remote client will provide
1993 Affected files are lib/silcclient/client_ftp.c and
1994 lib/silcclient/silcapi.h.
1996 * Extended the FILE SEND command to support defining the
1997 local IP and port for key exchange listener. They are
1998 optional. Affected file irssi/src/silc/core/silc-servers.c.
2000 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2002 * Defined to WHOIS command reply the sending of fingerprint
2003 of the client's public key (if the proof of posession of the
2004 corresponding private key is verified by the server).
2005 Updated to the protocol specification.
2007 * Added support of receiving the client's public key's
2008 fingerprint in command reply in client library. Affected
2009 file is lib/silcclient/command_reply.c, and
2010 lib/silcclient/idlist.[ch].
2012 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2014 * Do not send over 128 chars long nickname to the server
2015 in NICK command. Affected file lib/silcclient/command.c.
2017 * Do not send over 256 chars long channel names to the server
2018 in JOIN command. Affected file lib/silcclient/command.c.
2020 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Assure that silc_server_close_connection cannot be called
2023 twice for same socket context. Affected file is
2026 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Send error message to application if opening file for
2029 writing during file transfer fails. Affected file is
2030 lib/silcclient/client_ftp.c.
2032 Remove all file transfer sessions for a client that we're
2033 removing from ID cache.
2035 Affected file is lib/silcclient/client_ftp.c.
2037 * Fixed silc_net_addr2bin to return correct address. Affected
2038 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2040 * Fixed file transfer session removing on signoff notify.
2041 Affected file irssi/src/silc/core/silc-servers.c.
2043 * Added the SilcClientFileError to be returned in the monitor
2044 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2045 Affected file lib/silcclient/silcapi.h.
2047 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2049 * Fixed a crash in silc_client_ftp_free_sessions and
2050 silc_client_ftp_session_free_client. Affected file
2051 lib/silcclient/client_ftp.c.
2053 * Added `disabled' field in the SilcChannelEntry in the server
2054 to indicate if the server entry is disabled. Affected file
2055 silcd/idlist.h, silcd/command[_reply].c.
2057 * SILC server adds now /var/run/silcd.pid everytime it is
2058 started. Affected file silcd/silcd.c.
2060 * Added silc_server_packet_send_clients to send a packet to
2061 the provided table of client entries. Affected file
2062 silcd/packet_send.[ch].
2064 * Fixed a crash in client resolving in client_prvmsg.c in
2065 client library. Affected file lib/silcclient/client_prvmsg.c.
2067 * Do not actually remove the client directly from ID cache
2068 during SERVER_SIGNOFF, but invalidate it. This way we
2069 preserve the WHOWAS info for the client. Affected file
2070 silcd/server_util.c.
2072 * Fixed SERVER_SIGNOFF notify handling in the server. The
2073 server is now able to process incoming SERVER_SIGNOFF notify
2074 for a server that it doesn't even know about. It will remove
2075 the clients provided in the notify. Affected file
2076 silcd/packet_receive.c.
2078 * Check for partial packet in data queue after every packet that
2079 was found from the queue. Return and wait for more data if
2080 there is partial data in queue. Affected file is
2081 lib/silccore/silcpacket.c.
2083 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2085 * Added SilcClietFileError enum to indicate error in
2086 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2087 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2088 Affected files lib/silcclient/silcapi.h and
2089 lib/silcclient/client_ftp.c.
2091 * Check that newsize in silc_buffer_realloc is larger than
2092 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2094 * Added better monitor of file transfers. It now monitors
2095 key agreement protocol during the file transfer too. Added
2096 error reporting too. Affected files
2097 irssi/src/silc/core/silc-servers.c,
2098 irssi/src/fe-common/silc/module-formats.[ch].
2100 * Wrote a help file for FILE command.
2102 * Added silc_rng_global_get_byte_fast to get not-so-secure
2103 random data as fast as possible. Random data is read from
2104 /dev/urandom if available and from the SILC RNG if not
2105 available. It is used in padding generation. Affected file
2106 lib/silccrypt/silcrng.[ch].
2108 * All packets in client library are now processed synchronously.
2109 Optimized packet processing a lot. Affected file
2110 lib/silcclient/client.c.
2112 * All server connection packets are processing synchronously
2113 now in server, to optimize packet processing. Affected file
2116 * Include files are installed now only in Toolkit distribution
2117 if make install is given. Affected files: all Makefile.am's.
2119 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2121 * Assure that silc_client_notify_by_server_resolve does not
2122 resolve the client information multiple times. If it cannot
2123 be found by the first it cannot be found at all. Affected
2124 file lib/silcclient/client_notify.c.
2126 * Fixed WHOWAS command reply calling. Affected file
2127 lib/silcclient/command_reply.c.
2129 * Removed all references to silc_idlist_get_client from the
2130 Irssi SILC client since that call is internal call used by
2131 the library. The Irssi SILC client will use now client
2132 retrieval functions found in silcapi.h.
2134 * Fixed a bug in resolving nickname info before sending
2135 private message. It used freed memory. Affected file
2136 irssi/src/silc/core/silc-servers.c.
2138 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2140 * Assure my_channels statistics cannot go negative in server.

2157 * Added silc_net_localip to return local host's IP address.
2158 Affected file lib/silcutil/silcnet.[ch].
2160 * If key exchange or rekey protocol is active for a connection
2161 parse all packets syncronously since there might be packets
2162 in packet queue that we are not able to process without first
2163 processing packets before them. Affected file silcd/server,
2164 lib/silcclient/client.c.
2166 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2167 whether library should continue processing the packet.
2168 Affected file lib/silccore/silcpacket.h.
2170 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2171 SilcSFTPMonitorData to SFTP server to monitor various

2199 lib/silcutil/silcutil.[ch].
2201 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2203 * Resolve the client info when received private message or
2204 channel message for a client which nickname we don't know.
2205 Affected files lib/silcclient/client_prvmsg.c and
2206 lib/silcclient/client_channel.c.
2208 * Do not crash in /KEY if client is not connected. Affected
2209 file irssi/src/silc/core/silc-channels.c.

2214 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2215 is incomplete and is being resolved, it won't be resolved
2218 Make sure also that USERS command reply does not resolve
2219 twice information. Affected file is
2220 lib/silcclient/command_reply.c.
2222 Make sure that silc_client_get_clients_by_list does not
2223 resolve twice same information.
2225 * Check for valid client->id in the silc_server_free_client_data.
2226 Affected file silcd/server.c.
2228 * Fixed /GETKEY nick@server not to crash if the server entry
2229 is not found. Affected file lib/silcclient/command.c.
2231 * Fixed the silc_server_check_cmode_rights to check the
2232 requested modes correctly. Affected file silcd/command.c.

2236 * Better checks for non-printable chars in nick added.
2237 Affected file silcd/command.c.
2239 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2241 * Call the silc_server_udpate_servers_by_server in the
2242 primary router that comes back online in the backup resuming
2243 protocol. Otherwise it routes packets wrong. Affected file
2244 silcd/server_util.[ch], silcd/server_backup.c.
2246 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2249 lib/silcutil/silcbuffmt.[ch].
2251 * Redefined the SILC packet header to include the padding
2252 length. Affected file lib/silccore/silcpacket.[ch].
2254 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2255 length for maximum padding up to 128 bytes). Affected
2256 file lib/silccore/silcpacket.h.
2258 * Removed all backwards support for old 0.5.x MAC thingies.
2259 The SILC packet header change makes it impossible to be
2260 backwards compatible.
2262 * Send the ENDING packet with timeout in the backup resuming
2263 protocol. This is to assure that all routers has connected
2264 to the primary router. Affected file silcd/server_backup.c.
2266 * Changed the RNG to take the first IV from random data. It
2267 used to take it from zero actually. Changed the RNG also
2268 to use /dev/urandom during session. /dev/random is used
2269 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2271 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * Changed the SILC packet header to have the first two bytes
2274 (the packet length) encrypted. Affected files aroung the
2275 code tree, lib/silccore/silcpacket.[ch]. Removed the
2276 SilcPacketCheckDecrypt callback. It is not needed anymore
2277 since the silc_packet_receive_process will determine now
2278 whether the packet is normal or special.
2280 * Implemented the unidirectional MAC keys. Affected files
2281 lib/silcske/silcske.c, silcd/protocol.c and
2282 lib/silcclient/protocol.c.
2284 * Implemented the packet sequence number to the MAC computation.
2285 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2286 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2287 lib/silcclient/protocol.c.
2289 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2291 * Allow backup router to announce servers. All servers
2292 announced by backup router are added to the global list
2293 automatically. Update hte server's socket to our primary
2294 router also when backup router announces a server.
2295 Affected file silcd/packet_receive.c.
2297 * Do not update the client->router in the function
2298 silc_server_udpate_clients_by_server if the client is on
2299 global list. We might fail to find any specific server
2300 for locally connected clients and local cell clients. They
2301 should still use the `from' and not `to' as client->router.
2302 This fixes backup router resuming protocol. Affected file
2303 silcd/server_util.c.
2305 * Decrease channel statistics count only if the channel
2306 deletion worked. Affected files are silcd/server.c and
2307 silcd/server_util.c.
2309 * Added silc_server_update_servers_by_server to update origin
2310 of all server entries. Used during backup router protocol.
2311 Affected files silcd/server_util.[ch], silcd/server.c. and
2312 silcd/backup_router.c.
2314 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2315 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2316 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2317 lib/silccrypt/silchmac.c.
2319 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2321 * Assure that router cannot reroute the same channel message
2322 to the sender. Affected file silcd/packet_receive.c.
2324 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Made better checks that the channel message is not sent
2327 to the router it came from. Affected file is
2328 silcd/packet_send.c. Fixed memory leak too.
2330 * Announce informations for incoming router connection, but
2331 only after checking if it is replaced by backup router.
2332 Affected file silcd/packet_receive.c.
2334 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2336 * Fixed the backup resuming protocol to work in multiple
2337 router environment. Affected file silcd/server_backup.c.
2339 * Route packet only to one router in the function
2340 silc_server_packet_send_to_channel. Affected file is
2341 silcd/packet_send.c.
2343 * Fixed silc_server_send_notify_dest to set the broadcast
2344 flag. Fixed the silc_server_send_notify_topic to actually
2345 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2346 Affected file silcd/packet_send.c.
2348 * Changed the SFTP Filesystem interface. Changed the
2349 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2350 the filesystem operation function. The SilcSFTPFilesystem
2351 is now a context that is allocated by all filesystem allocation
2352 functions and it already includes the operations structure
2353 and filesystem specific context. It is given as argument
2354 now to the silc_sftp_server_start. This made the interface
2355 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2356 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2358 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Changed the backup router adding and getting interfaces
2361 in the server. The router that will be replaced by the
2362 specified backup router is now sent as argument. Affected
2363 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2366 * Added silc_net_addr2bin_ne to return the binary form of
2367 the IP address in network byte order. Affected files
2368 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2370 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2372 * Check for existing server ID in silc_server_new_server
2373 and in silc_server_connect_to_router_final and remove the
2374 old entry if it exists. Affected file silcd/packet_receive.c,
2377 * Send the channel message always to only one router, either
2378 in upstream or downstream. Affected file is
2379 silcd/packet_send.c.
2381 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2383 * Wrote the definition of the backup resuming protocol to the
2384 protocol specification.
2386 * Removed one redundant channel key generation from normal
2387 server during joining procedure. Removed one redundant
2388 channel key sending from server to router during joining
2389 procedure. Affected file silcd/command.c.
2391 * Made minor bugfixes to the backup router resuming protocol.
2392 Affected file silcd/server_backup.c, server.c.
2394 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Added --disable-asm configuration option. Affected files
2397 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2400 * Implemented the backup resuming protocol that is used to
2401 resume the primary router position in the cell after the
2402 primary router comes back online. Affected files
2403 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2404 and silcd/server_util.[ch].
2406 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Sleep two (2) seconds after sending QUIT command to server.
2409 Affected file lib/silcclient/command.c.
2411 * Assure that if outgoing data buffer is pending do not force
2412 send any data. Affected file silcd/packet_send.c.
2414 * Assure that if outgoing data buffer is pending do not force
2415 send any data. Affected file lib/silcclient/client.c.
2417 * Implemented the backup router support when the primary router
2418 goes down. The servers and routers can now use the backup
2419 router as new primary router without loosing connectivity.
2421 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2423 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2424 in the server to indicate disabled entry. All data read
2425 from the connection will be ignored and no data is sent
2426 for entry that is disabled. Affected files are
2427 silcd/idlist.h, silcd/server.c.
2429 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * Created SFTP client and server test programs in the
2432 lib/silcsftp/tests directory.
2434 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Implemented memory filesystem (virtual filesystem) for
2437 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2440 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2442 * Implemented the SFTP (SSH File Transfer Protocol) to the
2443 lib/silcsftp. It includes SFTP client and SFTP server
2446 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2448 * Moved lib/silccore/silcprotocol.[ch] to the
2449 lib/silcutil library.
2451 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2452 take variable argument list pointer as argument. Affected
2453 file lib/silcutil/silcbuffmt.[ch].
2455 * Added silc_buffer_set function that is used to set data
2456 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2457 Affected file lib/silcutil/silcbuffer.h.
2459 * Changed various routines in the core library to use the new
2460 silc_buffer_set instead of allocating new buffer only for
2463 * Added 64-bit value formatting and unformatting support to the
2464 silc_buffer_[un]format routines. Affected file is
2465 lib/silcutil/silcbuffmt.[ch].
2467 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2468 to includes/bitmove.h.
2470 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2472 * Fixed channel user mode saving in client library. Affected
2473 file lib/silcclient/command[_reply].c.
2475 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Defined the file transfer to the SILC Protocol. Added
2478 new packet type SILC_PACKET_FTP and defined File Transfer
2479 Payload. The mandatory file transfer protocol is SFTP
2480 (SSH File Transfer Protocol). Affected file in addition
2481 of the internet draft is lib/silccore/silcpacket.h.
2483 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2484 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2485 is used as part of backup router protocol when the primary
2486 router of the cell is back online and wishes to resume
2487 the position as primary router.
2489 * Redefined the MAC generation keys in the protocol. The
2490 same key is not used anymore in both direction. Both
2491 direction will now use different keys for sending and
2492 receiving. This fixes a potential security flaw. This
2493 change causes incompatibilities in the protocol.
2495 * Redefined also the MAC computation from the packet.
2496 An packet sequence number is now added to the MAC
2497 computation. This prevents possible replay attacks against
2498 the protocol. This change too causes incompatibilities
2501 Added `sequence' field to the SilcPacketContext to hold
2502 the current sequence number for the packet.
2504 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2506 * Added `created' field to the SilcIDListData in the file
2507 silcd/idlist.h to indicate the time when the entry was
2510 * Added `created' field to the SilcChannelEntry too. Affected
2511 file silcd/idlist.h.
2513 * Added `creation_time' aguments to all the announcement functions
2514 in the server. If it is provided then only the entries that
2515 was created after the provided time frame are actually
2516 announced. Affected file silcd/server.[ch].
2518 * The protocol says that the Channel ID's IP address must be
2519 based on the router's IP address. Added check for this in
2520 the silc_server_new_channel when processing incoming New Channel
2521 Payload. Affected file silcd/packet_receive.c.
2523 * Print out the correct version with --version in SILC client.
2524 Affected file irssi/src/silc/core/silc-core.c.
2526 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2528 * Fixed WHOWAS command to check for completnes of the client
2529 entry always, not just when the command is coming from client.
2530 Affected file silcd/command.c.
2532 * Added new function silc_server_packet_queue_purge to purge the
2533 outgoing data queue to the network. After the function returns
2534 it is guaranteed that the outgoing packet queue is empty.
2535 Affected file silcd/packet_send.[ch].
2537 * Purge the outgoing packet queue in the rekey protocol's final
2538 callback to assure that all rekey packets go to the network
2539 before quitting the protocol. Affected file silcd/server.c.
2541 * Added silc_client_packet_queue_parse as similar function as
2542 in server to the client library. The affected file is
2543 lib/silcclient/client.c.
2545 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Splitted silcd/server.c and created silcd/server_util.[ch]
2548 for utility functions.
2550 * Added new socket flag SILC_SF_DISABLED to indicate that the
2551 connection is open but nothing can be sent to or received from
2552 the connection. Affected file lib/silcutil/silsockconn.[ch].
2553 The checking for disabled socket is checked in the low level
2554 silc_socket_write and silc_socket_read functions.
2556 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2558 * Allow only nicknames and channel names that fits into the
2559 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2561 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2563 * When processing JOIN command reply in server check that if
2564 the channel exists in our global list we'll move it the local
2565 list. Affected file silcd/command_reply.c.
2567 * Fixed the check whether client is joined on the channel already
2568 in JOIN command. Affected file lib/silcclient/command.c.
2570 * Fixed the JOIN command reply to check whether the channel
2571 already exists. Affected file lib/silcclient/command_reply.c.
2573 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * Added silc_ske_status_string to map the SKE error numbers
2576 to readable strings. The affected files are
2577 lib/silcske/silcske[_status].[ch].
2579 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Do not show the private channels on the WHOIS channel list
2582 as it is not allowed by the protocol. The affected file is
2585 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Assure that the packet length digged from the actual packet
2588 is something sensible in the silc_packet_decrypt_rest_special
2589 in lib/silccrypt/silcpacket.c.
2591 * Free and NULL the allocated pointer in silc_hmac_alloc if
2592 the HMAC allocation fails. The affected file is
2593 lib/silccrypt/silchmac.c.
2595 * Print the selected security properties to the log files in
2596 the server. Affected file silcd/protocol.c.
2598 * Add SKE's reference counter even if calling the completion
2599 callback manually. Otherwise it goes negative, although it
2600 does not cause any problems. The affected file is
2601 lib/silcske/silcske.c.
2603 * Remove the client entry with short timeout after giving the
2604 KILL command. Affected file lib/silcclient/command.c.
2606 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2607 case all found clients are already disconnected (WHOWAS would
2608 found them) in the server. Affected file silcd/command.c.
2610 * Update the last_receive (time of last data received) to be
2611 updated only when received private or channel message so that
2612 the idle time showed in WHOIS makes more sense.
2614 * Added boolean field `valid' in to the SilcClientEntry in the
2615 client library to indicate whether the entry is valid or not.
2616 This fixes the nickname change bug on channel when changing
2617 the nickname to be same than the old (like nick to Nick) the
2618 nickname formatter doesn't set the new nick anymore to Nick@host.
2619 Affected file lib/silcclient/idlist.[ch].
2621 * Now actually fixed the nickname changing on disconnection.
2622 Added new function silc_change_nick to the Irssi SILC Client.
2623 Affected file irssi/src/silc/core/client_ops.c,
2624 irssi/src/silc/core/silc-nicklist.[ch].
2626 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2628 * Check that the public key exists in the GETKEY command before
2629 trying to encode it. Affected file silcd/command.c.
2631 * Print some notifications on received public keys with GETKEY
2632 command in the Irssi SILC Client. Affected files are
2633 irssi/src/fe-common/silc/module-formats.[ch],
2634 irssi/src/silc/core/client_ops.c.
2636 * Use IDENTIFY command to resolve the server information in the
2637 GETKEY command instead of INFO command. Affected file
2638 lib/silcclient/command.c.
2640 * All command reply functions in the client library now calls
2641 the pending command reply callbacks even if an error has
2642 occurred. The server has done this a long time and now it was
2643 time to move the client library to this as well. Now all
2644 errors can be delivered back to the pending command reply
2645 callbacks if necessary. Affected files are
2646 lib/silcclient/command[_reply].[ch].
2648 * Change the nickname on disconnection back to the username
2649 because in reconnect the server will enforce it to it anyway.
2650 Affected file irssi/src/silc/core/silc-servers.c.
2652 * Fixed a config file parsing bug in the Irssi SILC client.
2653 Affected file irssi/src/silc/core/clientconfig.c.
2655 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2657 * When printing the channel mode on JOIN, verify that the
2658 channel key and channel's HMAC are valid. Affected file
2659 irssi/src/silc/core/client_ops.c.
2661 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2663 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2664 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2665 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2667 * Removed channel key rekey task deleting from the function
2668 silc_server_save_channel_key. Affected file silcd/server.c.
2669 Added explicit timeout task context instead that is used to
2670 delete the task if we are registering a new task before the
2671 new task has elapsed.
2673 * When channel key rekey occurs the client library now saves
2674 the old channel key for a short period of time (10 seconds) and
2675 is able to use it in case some is still sending channel
2676 messages encrypted with the old key after the rekey. Affected
2677 file lib/silcclient/[idlist.h|client_channel.c].
2679 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2681 * Added check to the silc_server_new_id_real to not accept
2682 new ID if it is the sender's own ID. Affected file is
2683 silcd/packet_receive.c.
2685 * Assure that we do not announce ourself or the one we've
2686 sending our announcements when we're router and are announcing
2687 servers to our primary router. Affected file silcd/server.c.
2689 * Fixed silc_server_command_identify_check_client to assemble
2690 correct WHOIS packet. It send corrupted WHOIS packet and
2691 caused problem with router to router connections. Affected
2692 file silcd/command.c.
2694 Fixed also silc_server_command_whois_check the same way
2695 as for the IDENTIFY command.
2697 * Added new SilcIDListStatus to the server in the SilcIDListData
2698 structure. The status now includes the current status of
2699 the entry (like registered, resolved etc.). Affected file
2700 silcd/idlist.[ch]. Defined a bunch of different status types
2701 as well. This replaced the old boolean registered field as well.
2703 Added resolve_cmd_ident field to the SilcClientEntry structure
2704 too so that if the entry is for example being resolved so
2705 another command may attach to the same pending command reply
2706 without requiring to resolve the same entry again. This concept
2707 should optimize the WHOIS and the IDENTIFY resolving under
2708 heavy load by taking away unnecessary resolving for entries
2709 that are being resolved already.
2711 Added support for adding multiple pending commands for one
2712 command idenfier. Affected file silcd/command[_reply].[ch].
2714 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2715 before deleting the data. Otherwise the hash table will have
2716 freed data in comparison functions. Affected file is
2717 silcd/command_reply.c.
2719 * Fixed silc_idlist_replace_client_id to add the new entry to
2720 the cache with NULL nickname. Otherwise there will be invalid
2721 memory as the nickname after the nickname is freed. Affected
2722 file silcd/packet_receive.c.
2724 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2725 saved into wrong slots because the previous number of entries
2726 was not taken into account. Affected file silcd/idlist.c.
2727 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2729 * If we are router and we receive JOIN notify to a channel that
2730 does not have any users then notified client is marked as the
2731 channel founder, as it is it. The affected file is
2732 silcd/packet_receive.c
2734 * Added to the extended hash table API's table_del_*ext functions
2735 the destructor as argument too, so that the caller can decide
2736 which destructor to use or whether to use destructor at all.
2737 Affected file lib/silcutil/silchashtable.[ch].
2739 * Fixed ID Cache purging. It actually deleted the entries from
2740 the hash table after the data was freed. The hash table ended
2741 up comparing freed memory. The affected file is
2742 lib/silccore/silcidcache.c.
2744 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2746 * Fixed Irssi SILC client's KILL command's HELP syntax.
2748 * The USERS command now resolves the detailed user information
2749 if the userinfo field is missing. Affected file is
2750 lib/silcclient/command_reply.c.
2752 * Do not print error in silc_file_read if the read file does
2753 not exist. Just silently return NULL. Affected file is
2754 lib/silcutil/silcutil.c.
2756 * Fixed the silc_log_output to not wine about NULL filename
2757 and to not create some bogus " " filename. Affected file is
2758 lib/silcutil/silclog.c.
2760 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2762 * Fixed various printing bugs on the user interface in the
2763 Irssi SILC Client. Minor changes that were forgotten from
2766 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2768 * Fixed the configure.in.pre and the compilation and distribution
2769 environment to support the new autoconf 2.52. That version is
2770 now required to compile the CVS trunk.
2772 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2775 to generally parse user@fqdn format strings. Affected file
2776 lib/silcutil/silcutil.c.
2778 * Added nickname_format and nickname_force_format fields to the
2779 SilcClientParams structure. The first one defines the format
2780 for the nicknames that the library will enforce if the receives
2781 multiple same nicknames. The second one is boolean value and
2782 can be used to force the library to always enforce the format
2783 to the nicknames regardles whether there are multiple nicknames
2784 or not. This configurable formatting was employed to flexibly
2785 support accessing multiple nicknames from the user interface.
2786 The userinterface can now set the nicknames to what ever format
2787 they prefer. Affected file lib/silcclient/silcapi.h.
2789 Added function silc_client_nickname_format to the file
2790 lib/silcclient/idlist.c. It performs the nickname formatting.
2792 Added new field `hostname´ to the SilcClientEntry context.
2793 It holds the hostname of the client. Affected file is
2794 lib/silcclient/idlist.h.
2796 * Irssi SILC Client sets the nicknames in nick@hostn format.
2797 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2798 irssi/src/silc/core/silc-core.c.
2800 The WHOIS printing now also shows both the real nickname and
2801 the formatted nickname so that user knows how to access the
2802 user if there are multiple same nicknames cached. Affected
2803 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2804 printing formatting too to take the hostname now as a separate
2805 argument. The Affected file is
2806 irssi/src/fe-common/silc/modules-formats.[ch].
2808 * Changed the silc_client_get_clients_local to accept the formatted
2809 nickname as argument. It accepts the real nickname too but the
2810 formatted nickname can be used to find the true entry from
2811 multiple entries. Affected file lib/silcclient/silcapi.h and
2812 lib/silcclient/idlist.c.
2814 * Added nickname_format_parse field to the SilcClientParams.
2815 It is a callback function provided by the application to parse
2816 the nickname out of the formatted nickname string. The library
2817 calls it to get the nickname from the formatted string. Since
2818 the application generally knows better the format of the nickname
2819 string it parses it instead of the library, even though library
2820 encodes the formatted string. If the callback function is not
2821 provided then the library will use the string as is. The
2822 affected file is lib/silcclient/silcapi.h.
2824 * All the nickname strings passed to the client library in
2825 commands are now expected to be formatted nickname strings.
2826 If the command does not support the formatted nickname string
2827 it will assume that the sent string is the actual nickname.
2828 Affected file lib/silcclient/command.c.
2830 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2832 * Added public key authentication support to OPER and SILCOPER
2833 commands in the client library. Affected file is
2834 lib/silcclient/command.c.
2836 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2838 * Changed the get_auth_methdod client operation to be asynchronous.
2839 It can be async if the application resolves the authentication
2840 method from the server during the negotiation. Added new
2841 SilcGetAuthMeth completion callback that the application will
2842 call after resolving the authentication method.
2844 Added function silc_client_request_authentication_method that
2845 the application can use to resolve the authentication method
2846 from the server. Added also SilcConnectionAuthRequest callback
2847 that the library will call after the server has replied. The
2848 application can call this function if it does not know the
2849 current authentication method.
2851 Affected files are lib/silcclient/client.c and
2852 lib/silcclient/silcapi.h.
2854 * The Irssi SILC client now automatically resolves the authentication
2855 method incase any configuration information is not present (and
2856 currently there never is). The affected file is
2857 irssi/src/silc/core/client_ops.c.
2859 * Fixed public key authentication from the client library.
2860 Affected file lib/silcclient/protocol.c. Changed also the
2861 protocol specification about the public key authentication in
2862 the connection authentication protocol. The actual data to be
2863 signed is now computed with a hash function before signing.
2865 * Fixed the public key authentication from the server as well.
2866 Affected file silcd/protocol.c.
2868 * Removed the mlock()'s from the memory allocation routines.
2869 Affected file lib/silcutil/silcmemory.c. The ./configure does
2870 not check anymore for the mlock(). Affected file is
2873 * Fixed USERS command in server to allow the execution of the
2874 command for private and secret channels if the client sending
2875 the command is on the channel. Affected file silcd/command.c.
2877 * Fixed silc_client_get_clients_local to return the clients
2878 count correctly. It could return wrong value. Affected file
2879 lib/silcclient/idlist.c.
2881 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2884 types. The assembler optimizations seemed not to like 64-bit
2885 data types. The assmebler optimizations thus are now enabled
2886 also for BSD systems as opposed to only enable them for Linux.
2888 * Do not check for threads at all on BSD systems. Affected
2889 file configure.in.pre.
2891 * Removed -n and -h options from the Irssi SILC Client since
2892 they are not used in silc.
2894 * Fixed the prime generation to assure that the first digit
2895 of the generated random number is not zero since our conversion
2896 routines does not like number strings that starts with zero
2897 digit. If zero digit is seen the random number is regenerated.
2898 This caused some corrupted RSA keys when the zero first digit
2899 was met. Affected file lib/silcmath/silcprimegen.c.
2901 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * Fixed WIN32 configuration in the ./configure script.
2904 Fixed to include xti.h on environments that has it.
2905 Patches by Carsten Ilchmann and andrew.
2907 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2909 * Changed the silc_id_create_client_id to be collision
2910 resistant. It is now assured that there cannot be created
2911 two same client ID's. I suspect that some weird bugs in
2912 the server were actually caused by duplicate Client IDs.
2913 Affected file silcd/serverid.[ch]. A router receiving
2914 new ID now also assures and informs the sending server
2915 if the ID caused collision.
2917 * Changed the silc_id_create_channel_id to also assure that
2918 there are no collisions.
2920 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2922 * Statement about ignoring the Mutual Authentication flag when
2923 performing rekey with PFS was a bit misleading. It is ignored
2924 if it was set in the initial negotiation, it cannot be even
2925 set in the rekey. Fixed in the ke-auth draft. Started the
2926 new versions of the protocol drafts in the doc/.
2928 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2930 * Fixed a bug in silc_client_command_identify_save when saving
2931 new channel information. The channel name was no duplicated
2932 and caused crash on exit. Affected file is
2933 lib/silcclient/command_reply.c.
2935 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Fixed the getkey command handling in the server. Send just
2938 empty OK reply to the sender if the key could not be fetched
2939 (but everything else was ok, like the key just was not available).
2940 Changed the public key parameter to optional in the protocol
2941 specs so that empty OK reply can be sent. Affected file
2944 Added a message to Irssi SILC client to tell to user if the
2945 server did not return a public key.
2947 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2949 * Fixed a channel key regeneration bug. It registered new
2950 timeout tasks exponentially until all system resources were
2951 used. Affected file silcd/server.c.
2953 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2955 * Added the SILC Document generator to the scripts/silcdoc.
2956 It can be used to generate the Toolkit Reference Manual out
2957 of the source tree. Internally it will also use the RoboDoc
2958 generator now imported in util/robodoc.
2960 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2962 * Added couple of return's in rekey protocol if error orccurred
2963 during the protocol. The execution must be terminated.
2964 Affected file silcd/protocol.c. Also, terminate the protocol
2965 always with timeout.
2967 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2969 * The client's Client ID was created initally from the wrong
2970 nickname (it could have been in format nick@host) in the
2971 silc_server_new_client. Affected file silcd/packet_receive.c
2973 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Added some SILC_LOG_ERROR's to various error conditions
2976 if client could not be added to ID cache. Affected files
2977 silcd/packet_receive.c and silcd/server.c.
2979 * When client's sock->user_data is freed, NULL also the
2980 client->router and client->connection pointers. Added check
2981 for these pointers being NULL to various places around the
2982 code. Affected file silcd/server.c.
2984 * Added client->data.registered == TRUE checks to various
2985 places around the code to assure that unregistered client's
2986 are not handled when it is not allowed. Affected file
2989 * Added `bool registered' fields to all
2990 silc_idlist_[server|client]_get_* routines to indicate whether
2991 the fetched client needs to be registered or not. Affected
2992 file silcd/idlist.[ch].
2994 * Add your own entry as registered to the ID cache in the
2995 server. Affected file server.c.
2997 * Fixed a bug in silc_server_new_server. The SilcServer was
2998 set as the new server's context instead of SilcServerEntry.
2999 This naturally caused some weird bugs.
3001 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3003 * Do not delete the channel rekey task when adding it
3004 for in silc_server_create_channel_key.
3006 * Changed the silc_server_create_channel_key to return
3007 TRUE or FALSE to indicate the success of the channel key
3010 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3012 * Fixed MSVC++ project files and added missing files to
3013 Makefiles under win32/.
3015 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Do not add TCP_NODELAY flag if the operating system
3018 does not have it defined. Affected files are
3019 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3021 * Fixed buffer overflow from Irssi SILC Client. Affected
3022 file irssi/src/fe-common/core/themes.c.
3024 * Fixed double free in client library in the file
3025 lib/silcclient/client.c when disconnecting from server.
3027 * Applied double free patch from cras to Irssi SILC client.
3028 Affected files irssi/src/core/[modules/expandos].c
3030 * Fixed the disconnection handling to Irssi SILC Client.
3031 The application must call silc_client_close_connection
3032 in ops->connect client operation in case of failure of
3033 the connection. Affected file is
3034 irssi/src/silc/core/client_ops.c.
3036 * Do not set sock->protocol to NULL in the function
3037 silc_client_close_connection after executing the protocol's
3038 final callback since the sock might not be valid anymore.
3039 Affected file lib/silcclient/client.c.
3041 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3043 * Do not enable SILC_THREADS if the linking with libpthread
3044 did not happen. Affected file configure.in.pre.
3046 * Added notion to protocol specification that server must
3047 verify the sent authentication payload with CMODE when
3048 setting the channel founder key. Implemented it to the
3049 server. Affected file silcd/command.c.
3051 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3053 * Added _EXTRA_DIST SILC distribution variable to the
3054 distributions file. It is used to conditionally add extra
3055 files or directories to the specific distribution. Affected
3056 files ./prepare, Makefile.am.pre and distributions.
3058 Removed the `_' from the start of the distribution names.
3061 * Added README.WIN32 for instructions to compile the Toolkit
3064 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Fixed a double free in disconnection in the server. Affected
3067 file is silcd/server.c.
3069 * Fixed the lib/silcske/groups.c to work now also with GMP
3070 MP library. The string conversion did not work when using
3071 specific base and the base is indicated in the string as well.
3073 * Created win32/ directory which now includes MSVC++ specific
3074 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3075 It will appear only in the toolkit distribution
3077 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3079 * Changed the key material distribution function in case when
3080 the hash output is too short. The data is now concatenated
3081 a bit differently than it used to. Made the change to the
3082 SKE protocol specification.
3084 * Added better GMP detection to configure.in.pre. A patch
3087 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3089 * Fixed a minor bug in SKE that might cause some problem on
3090 some platforms. Affected file lib/silcske/silcske.c.
3092 * Added the cookie checking for initiator in the SKE. It checks
3093 that the responder returns the sent cookie unmodified. The
3094 affected file is lib/silcske/silcske.c. Added new SKE
3095 error type INVALID_COOKIE that can be sent during the
3096 negotiation. Fixed some memory leaks as well.
3098 * Added the "invalid cookie" error message to Irssi SILC client's
3101 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3103 * Added `task_max' field to the SilcClientParams to indicate
3104 the maximum tasks the scheduler can handle. If set to zero,
3105 default values are used. Affected file lib/silcclient/silcapi.h.
3107 * Fixed memory leaks in silc_client_close_connection. Affected
3108 file lib/silcclient/client.c.
3110 * Added silc_client_del_client_entry to client library to free
3111 all memory of given client entry. Affected file is
3112 lib/silcclient/idlist.[ch].
3114 * Added new functions silc_client_del_channel and
3115 silc_client_del_server to delete channel and server entries.
3116 Affected file lib/silcclient/[silcapi.h/idlist.c].
3118 * Removed silc_client_del_client_by_id from silcapi.h.
3120 * Fixed the INFO command to return the server's own info
3121 correctly when querying by Server ID. Affected file is
3124 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3126 * Removed the non-blocking settings in WIN32 code in the
3127 silc_sock_[read/write] and added SleepEx instead. Affected
3128 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3129 of input data is now checked with FIONREAD and ioctlsocket.
3131 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Call silc_schedule_task_del_by_context in the
3134 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3135 Affected file lib/silccore/silcprotocol.c.
3137 * Call silc_protocol_cancel for active protocols in the
3138 silc_server_close_connection if the funtion
3139 silc_server_free_sock_user_data has not been called.
3140 Affected file silcd/server.c.
3142 * Generic tasks cannot be deleted using the del_by_fd
3143 task deleting function since generic tasks does not match
3144 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3146 * Added a notion to SILCOPER help file that the SILCOPER works
3147 only on router server, not on normal server.
3149 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3151 * Added for WIN32 support for the new scheduler as well.
3152 Affected file lib/silcutil/win32/silcwin32schedule.c.
3154 * Fixed the SHA1 implementation to work on various platforms.
3156 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3158 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3159 API. It is part of the scheduler now. Everything else is
3160 as previously but some functions has changed their names.
3161 Checkout the lib/silcutil/silcschedule.h for the interface.
3162 Updated all applications to use the new interface. Affected
3163 files are lib/silcutil/silcschedule.[ch].
3165 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3167 * Found a bug in the SKE implementation. The HASH value,
3168 specified by the protocol, was not computed correctly. The
3169 public key of the responder was not added to the computation
3170 even though it is mandatory. Affected file lib/silcske/silcske.c.
3171 This unfortunately causes incompatibilities with older
3172 clients and servers.
3174 * Added WIN32 specific network init and uninit functions:
3175 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3176 the Winsock2. Affected file lib/silcutil/silcnet.h and
3177 lib/silcutil/win32/silcwin32net.c.
3179 * Set the socket always to nonblocking mode on WIN32 after
3180 reading data or writing data. Affected file is
3181 lib/silcutil/win32/silcwin32sockconn.c.
3183 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3185 * Fixed various compilation problems under WIN32. Affected
3186 files lib/silcutil/win32/silcwin32thread.c and
3187 lib/silcutil/win32/silcwin32schedule.c.
3189 * Removed all _internal.h #includes from public header
3190 files. Internal headers must never be included from
3193 Removed also the lib/silcske/payload_internal.h file.
3195 * All include files that may be needed (public and some others
3196 included by the public headers) by application developers are
3197 now copied to the ./includes directory. It does not copy any
3198 internal headers. Affected file Makefile.defines.pre and all
3199 Makefile.am's under lib/ and subdirs.
3201 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3203 * Do not change the ~/.silc directory's permissions automatically.
3204 Affected file irssi/src/silc/core/clientutil.c.
3206 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3208 * Do not cancel the protocol in silc_server_close_connection
3209 it might cause recursion. Now cancelled in the function
3210 silc_server_free_sock_user_data. Affected file silcd/server.c.
3212 * Fixed the silc_server_remove_clients_by_server to regenerate
3213 the channel keys correctly finally. Added also new function
3214 silc_server_remove_clients_channels to actually do it.
3215 Affected file silcd/server.c.
3217 * Fixed the silc_server_new_channel to not crash by giving
3218 wrong router to the new channel. Affected file is
3219 silcd/packet_receive.c.
3221 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3224 which is given as argument to the silc_client_alloc now.
3225 It can be used to configure the client and set various parameters
3226 that affect the function of the client.
3228 * The USERS command in server did not check whether the channel
3229 is private or secret. Affected file silcd/command.c.
3231 * Added new argument to the USERS command in protocol specification.
3232 The USERS command now can take the channel name as argument
3233 as well. Added support for this in client and server and
3234 updated the protocol specs.
3236 * Completed the GETKEY command in client. It can be now used
3237 to fetch also servers public key not only some clients.
3238 Affected files lib/silcclient/command[_reply].c.
3240 * Added silc_client_get_server to return server entry by the
3241 server name. Affected files lib/silcclient/silcapi.h and
3244 * Redefined the IDENTIFY command in protocol specification to be
3245 more generic. It now can be used to query information about
3246 any entity in the SILC Network, including clients, servers and
3247 channels. The query may be based either the entity's name
3248 or the ID. Added support for this in both client and server.
3250 Affected files silcd/command.c and lib/silcclient/command.c
3251 and command_reply.c.
3253 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3254 the _from_client and _from_server functions. Affected file
3257 * Added silc_client_get_channel_by_id_resolve to the file
3258 lib/silcclient/silcapi.h to resolve channel information by
3259 its ID. Added also silc_client_get_channel_by_id that
3260 does not resolve it from the server.
3262 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3264 * Added SilcServerEntry context into the client library
3265 to represent one server. The INFO command now allocates
3266 these to save the resolved server info. For now on the
3267 client library will also keep information about servers,
3268 connected and resolved with INFO.
3270 The INFO command now allocates the SilcServerEntry context
3271 and saves the server info there. The COMMAND_REPLY in
3272 the INFO now returns the parameters to application in
3273 same order as defined in the protocol specification.
3275 The entries are cached in the client->server_cache.
3277 * The INFO command is now issued after received the Client ID
3278 from the server. Affected file lib/silcclient/client.c.
3280 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3281 to the application as the mode changer might be server.
3282 It is guaranteed that NULL is not returned anymore to the
3283 application. Affected file lib/silcclient/client_notify.c.
3285 The ID Type is now also passed to the application so that
3286 it can check whether the returned entry is SilcClientEntry
3289 Added new function silc_client_get_server_by_id to return
3290 the server entry by ID. Affected files are the
3291 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3293 * Do not create the channel in the Irssi SILC Client when issuing
3294 the JOIN command but when received the sucessful JOIN command
3295 reply. Otherwise the channel might get created even though we
3296 could not join it. The Affected file is
3297 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3299 * Fixed a channel joining bug in router. The router must also
3300 check the channel modes, invite and ban lists etc. when serving
3301 the JOIN command sent by normal server. Affected file is
3302 silcd/command.c. The router now resolves the client's
3303 information from the server who sent the JOIN command if it
3304 does not know it, and processes the JOIN command only after
3307 * Changed the SilcCommandCb to take new argument; void *context2.
3308 Affected file lib/silccore/silccommand.h
3310 The second argument in the command callbacks in the server now
3311 includes the SilcServerCommandReplyContext if the command was
3312 called as pending command callback from the command reply.
3313 Otherwise it is NULL. When called as pending the status of the
3314 command reply will be checked and if it was erronous the
3315 error will be sent to the original sender of the command.
3316 This way the client always receives the error messages even
3317 though the server was actually the one who received the error
3318 when it resent the command to router, for example. Affected
3319 files silcd/command[_reply].[ch].
3321 * Fixed sending WHOWAS command's error message to client if
3322 the requested client could not be found. It was missing.
3325 * Changed the CMODE and CUMODE commands reply arguments in the
3326 protocol specification. The Channel ID is now sent in both
3327 of the commands to identify the channel. Implemented this
3328 new feature to the client and server. Affected files
3329 lib/silcclient/command_reply.c and silcd/command.c.
3331 * Made better checks for invite and ban lists in the JOIN
3332 command in server. Affected file silcd/command.c.
3334 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3336 * The server now performs the incoming host IP/DNS lookup
3337 using the silc_socket_host_lookup and thus does not block
3338 the server anymore. Affected file silcd/server.c.
3340 * Completed the multi-thread support for SILC Scheduler in
3341 the lib/silcutil/silcschedule.c.
3343 * Fixed the configure.in.pre to detect the pthread correctly
3346 * Fixed a deadlock in silc_task_queue_wakeup in the file
3347 lib/silcutil/silctask.c.
3349 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3351 * Added new function silc_schedule_wakeup that is used in
3352 multi-threaded environment to wakeup the main thread's
3353 schduler. It needs to be used when a thread adds a new task
3354 or removes a task from task queues. After waking up, the
3355 scheduler will detect the task queue changes. If threads
3356 support is not compiled in this function has no effect.
3357 Implemented the wakeup mechanism to both Unix and WIN32
3358 systems. Affected files are lib/silcutil/silcschedule.[ch],
3359 lib/silcutil/unix/silcunixschedule.c and the
3360 lib/silcutil/win32/silcwin32schedule.c.
3362 * Added new function silc_task_queue_wakeup to wakeup the
3363 scheduler by the specified task queue. Affected file
3364 lib/silcutil/silctask.[ch].
3366 * The silc_socket_host_lookup_start now wakes up the scheduler
3367 after adding the timeout task. Affected file is
3368 lib/silcutil/silcsockconn.c.
3370 * The silc_socket_host_lookup is synchronous now if the threads
3371 support is not compiled in. However, the callback is still
3372 called asyncronously through the scheduler, anyway. Affected
3373 file lib/silcutil/silcsockconn.c.
3375 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3377 * Added new function silc_socket_host_lookup to perform
3378 asynchronous IP and FQDN lookups for the socket connection.
3379 Affected files lib/silcutil/silcsockconn.[ch].
3381 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3383 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3384 that may or may not compile the mutex support in.
3386 Changed the silc_mutex_alloc interface. It allocates the
3387 mutex now to the sent pointer and returns TRUE or FALSE.
3389 Affected file lib/silcutil/silcmutex.h.
3391 * Wrote the SILC Task Queue interface to support multi-threads.
3392 Affected file lib/silcutil/silctask.[ch].
3394 * Wrote the SILC Scheduler to support multi-threads. Affected
3395 file lib/silcutil/silcschedule.c.
3397 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3399 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3400 in lib/silcutil/win32/.
3402 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3404 * Defined SILC Mutex API and SILC Thread API and implemented
3405 them for Unix. Affected files are
3406 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3407 lib/silcutil/unix/silcunixmutex.c and
3408 lib/silcutil/unix/silcunixthread.c.
3410 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3412 * Fixed the silc_server_remove_clients_by_server's channel
3413 key re-generation. The hash table handling was incorrect
3414 and would not work with many channels. Affected file is
3417 * Fixed some memory leaks around the server code.
3419 * Rewrote the silc_server_get_users_on_channel to support IPv6
3420 based Client ID's. Affected file silcd/server.c.
3422 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3423 specification. However, a separate document must be written
3424 to define the detailed signing procedure and the payload
3425 associated with the flag. Defined the flag to the
3426 lib/silccore/silcchannel.h as well.
3428 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3430 * Changed the dynamic tables to static size tables in the
3431 lib/silccrypt/silchmac.c.
3433 * Removed GCC dependencies from the code. A patch by cras.
3435 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3437 * Do not show the error "Error receiving packet bla bla"
3438 in server if it really was not an error (-2 means that reading
3439 is pending). Affected file silcd/server.c.
3441 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3443 * Fixed a possible crash in silc_server_remove_clients_by_server
3444 in silcd/server.c. Fixed there also some memory leaks.
3446 * Fixed the silc_idlist_replace_client_id. It could replace
3447 wrong key in the hash table. Affected file silcd/idlist.c.
3449 * Do not check whether there are global users on the channel
3450 if the channel->global_users is FALSE. Affected functions
3451 silc_server_remove_from_one_channel and
3452 silc_server_remove_from_channels in silcd/server.c. Also,
3453 do not check if the removed client is local as we can be
3454 sure that global client was not removed from the channel
3455 and checking for global users is not needed.
3457 * The silc_server_remove_clients_by_server now re-generates
3458 the channel keys correctly for those channels that had
3459 clients removed from them. Affected file silcd/server.c.
3461 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3463 * Found the reason of random crashes in the server. We weren't
3464 ignoring the SIGPIPE signal (which can be sent in write())
3465 and it crashed the server. Affected file silcd/silcd.c.
3467 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3469 * Assure that sock->user_data is not NULL in the function
3470 silc_server_packet_send in silcd/packet_send.c.
3472 * Disconnect the remote connection if it could not be added
3473 to any ID lists in the server. The affected file is
3476 * Check in silc_server_packet_send[_real/dest] that the
3477 socket is not disconnecting and ignore the data if it is.
3478 Affected file silcd/packet_send.c.
3480 * Define inline to __inline on native WIN32 compilation.
3481 Affected file includes/silcwin32.h.
3483 * Added some explicit type casts for inline code since MSVC
3484 require them. Affected files lib/silcutil/silcbuffer.h,
3485 lib/trq/silcdlist.h and lib/trq/silclist.h.
3487 * Print warning in log files from now on if the packet
3488 decryption fails. Affected file silcd/server.c.
3490 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3492 * Changed the `say' client operation's interface to accept
3493 new `type' argument to indicate the type of the message sent
3494 by the library. The application may filter the library's
3495 messages according the type. The affected file is the
3496 lib/silcclient/silcapi.h.
3498 * Added two new functions to lib/silcclient/silcapi.h:
3499 silc_client_del_client and silc_client_del_client_by_id.
3500 Affected file lib/silcclient/idlist.c.
3502 * Moved the clientincludes.h from includes/ to silc/ and
3503 serverincludes.h from includes/ to silcd/.
3505 * The modes for the CMODE and CUMODE are now passed as
3506 uint32 for application with COMMAND_REPLY. The affected
3507 file is lib/silcclient/command_reply.c.
3509 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3511 * /WHOIS without arguments shows client's own information.
3512 Affected file lib/silcclient/command.c.
3514 * Changed PING to not accept any arguments. The specs
3515 says that client can ping only the connected server so
3516 requiring an argument is not needed. Affected file is
3517 lib/silcclient/command.c.
3519 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3521 * Fixed a fatal bug in private message sending and reception
3522 encryption and decryption when using private message keys.
3523 The implementation was incorrect and did not follow the
3524 specification. It causd that some of the message were
3525 lost since it did not use the sending and receiving keys
3526 as the protocol suggests. This has been fixed and will cause
3527 incompatibilities with older clients when sending private
3528 message encrypted with private message keys. Affected files
3529 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3530 and various other in Irssi SILC Client.
3532 Added `responder' boolean argument to the functions
3533 silc_client_add_private_message_key[_ske] to indicate when
3534 the key is added as responder or initiator of the key
3537 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3539 * Removed the silc_ske_check_version function and created
3540 a SilcSKECheckVersion callback. Added also a function
3541 silc_ske_set_callbacks that is now used to set all SKE
3542 callbacks. The callback functions are not given to
3543 the SKE functions anymore, but this function is used to
3546 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3548 * Added `silc_version' argument to the silc_client_alloc
3549 to define the version of the application for the library.
3550 The library will use the version string to compare it
3551 against the remote host's (usually a server) version
3552 string. Affected file lib/silcclient/silcapi.h
3554 * Added the KE protocol context to Key Agreement context
3555 in client library so that we can abort the SKE if it
3556 is in process when we get timeout. Affected file is
3557 lib/silcclient/client_keyagr.c.
3559 * Do not resolve the client ID forever if it returns in the
3560 first time that such client does not exist. This was done
3561 for example with private message. Affected file is
3562 lib/silcclient/client_prvmsg.c.
3564 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3566 * Do not add regex.h for WIN32. The affected file
3567 includes/silcincludes.h.
3569 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3570 not work yet 100%. It generates the DLL's automatically
3571 when compiling with --with-win32 under cygwin.
3573 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3575 * lib/contrib/regex.c is not compiled on WIN32.
3577 * Added silc_net_get_socket_opt function to the
3578 lib/silcutil/silcnet.h.
3580 * Added includes/silcwin32.h for WIN32 specific includes
3583 * Do not use ptime structure or any of the posix process
3584 functions on WIN32 in lib/silccrypt/silrng.c.
3586 * Added silc_gettimeofday to provide generic function
3587 for struct timeval on all platforms. Added the function
3588 to lib/silcutil/silcutil.h.
3590 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3592 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3593 library as they clearly belong there. As a plus side we
3594 can make the actual socket connection routines platform
3597 Added also new generic function silc_socket_read and
3598 silc_socket_write (that used to be silc_packet_[read/write].
3599 The implementation of these are platform specific.
3601 * Added WIN32 specific routines of silc_socket_[read/write]
3602 to lib/silcutil/win32/silcwin32sockconn.c.
3604 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3606 * Added preliminary support for native WIN32 compilation under
3607 cygwin (using the -mno-cygwin option for GCC) to the
3608 ./configure.in.pre. The --with-win32 now prepares the
3609 compilation for native WIN32.
3611 * Rewrote the SILC Scheduler interface in the file
3612 lib/silcutil/silcschedule.h. The scheduler is now context
3613 based and does not have anymore any global static scheduler.
3614 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3615 and created lib/silcutil/win32 directory for WIN32 based
3618 * Added Unix specific network routines to the
3619 lib/silcutil/unix/silcunixnet.c and the old
3620 lib/silcutil/silcnet.c includes now only generic routines.
3622 Added WIN32 specific network routines to the
3623 lib/silcutil/win32/silcwin32net.c.
3625 * Added Unix specific utility functions from the
3626 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3628 * Added WIN32 SILC Scheduler to the file
3629 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3632 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3634 * Do not handle JOIN notify in the server if the target client
3635 is not registered (idata->registered == FALSE). The affected
3636 file is silcd/packet_receive.c.
3638 * Update the nickrec->founder in event_cumode in the Irssi SILC
3639 client. Affected file irssi/src/silc/core/silc-channels.c.
3641 * Fixed the CUMODE_CHANGE notify handling in the server when
3642 server and router are announcing their clients on channels.
3643 Now the mode changes are saved and notified correctly. The
3644 affected file is /silcd/packet_receive.c.
3646 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3647 They really did not replace the cache entry in the ID Cache.
3648 Now they do that. Affected file silcd/idlist.c.
3650 * Fixed the KICK notify handling in the Irssi SILC client to
3651 update the channel records so that the kicked client does not
3652 appear to be on the channel. The affected file is
3653 irssi/src/silc/core/silc-channels.c.
3655 * Always update the conn->current_channel when executing command
3656 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3658 * Fixed the KILL notify handling in Irssi SILC client to remove
3659 the killed client on all channels.
3661 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Fixed the silc_parse_command_line to remove extra spaces
3664 from the start and end of the arguments. Affected file is
3665 lib/silcutil/silcutil.c.
3667 * Cancel and free any active protocol in the function
3668 silc_server_close_connection. Affected file silcd/server.c.
3670 * Cancel and free any active protocol in the function
3671 silc_client_close_connction. Affected file is
3672 lib/silcclient/client.c.
3674 * Do not execute the KILL command for clients that are in
3675 history (ie. they are not in the network). Affected file is
3678 * Fixed KILL notify handling, client does not crash anymore.
3679 Affected file irssi/src/silc/core/silc-channels.c.
3681 * Reduced the default packet buffer size from 2048 to 1024 in
3682 lib/silccore/silcpacket.c.
3684 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3685 counter to the SKE context that is incresed when the SKE library
3686 performs async operation outside the library. If the outside
3687 process frees the SKE context and FREED status will be set
3688 and the library will detect after the sync operation that the
3689 libary is freed. The affected files are
3690 lib/silcske/silcske[_status].[ch].
3692 * Resolve the client entry information in the function
3693 silc_client_channel_message to assure that NULL pointer is not
3694 passed as client entry to the application. */
3696 * Fixed the task timeout calculation to assure that there is
3697 never negative timeouts. The affected file is
3698 lib/silcutil/silcschedule.c.
3700 * Fixed the channel user mode notification sending in server.
3701 It was sent point-to-point to the router (or to server by router)
3702 but it needs to be destined to a channel. The routines now
3703 supports sending the channel user mode notifys to the channels
3704 when announcing clients and channels. Affected files are
3705 silcd/server.c and silcd/packet_receive.c.
3707 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3708 It did not actually replace the old channel entry in the cache.
3709 Affected file lib/silcclient/client_notify.c.
3711 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3713 * Fixed a possible crash in silc_packet_send_prepare. It now
3714 assures always that there is enough space in the buffer and
3715 at the tail area of the buffer (for MAC).
3717 Fixed the inbound buffer reallocation in silc_packet_read.
3718 It was old code and did not handle the reallocation correctly.
3721 The affected file is lib/silccore/silcpacket.c.
3723 * Fixed buffer overflow in silc_parse_nickname in the file
3724 lib/silcutil/silcutil.c.
3726 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3728 * make install generates new server keys only if there is not
3731 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3734 Added check that if the NOREPLY is set then we will not send
3735 the away message. This avoids infinite loop of away messages
3736 if both clients are away. The affected file is
3737 lib/silcclient/client_prvmsg.c.
3739 * Fixed client crash if /NICK was given without arguments.
3740 Affected file lib/silcclient/command.c.
3742 * Server does not send the invite list in INVITE command back
3743 to the client if the list was not altered. Added this notion
3744 to the protocol spec as well. Affected file silcd/command.c.
3746 Fixed possible crash in INVITE command by checking the
3747 value of silc_server_get_client_route command.
3749 * Fixed the INVITE notify type handling. The arguments are now
3750 taken in correct order and client does not crash. The affected
3751 file is irssi/src/silc/core/silc-channels.c.
3753 Removed the "Inviting xxx to channel" message from the
3754 client library away and let the application handle it.
3755 Affected file lib/silcclient/command.c. Added that message
3756 to Irssi SILC client's message formats.
3758 * Fixed CMODE command crash in client. It now checks the
3759 amount of arguments correctly and does not crash. The affected
3760 file is lib/silcclient/command.c.
3762 * Do not create new channel automatically in silc_channels_join
3763 but check whether the channel by that name already exists.
3764 Affected file irssi/silc/core/silc-channels.c.
3766 * Do not send the SERVER_SIGNOFF to router if the disconnected
3767 entity was the router. Affected file silcd/server.c.
3769 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3770 SILC client as it was missing from there.
3772 Added the handling of the KICK notify to the Irssi SILC client
3773 as it was missing. Added "you have been kicked" message to
3774 Irssi SILC client's message modules formats.
3776 Added the handing of the KILL notify to the Irssi SILC client
3777 as it was missing. Added the kill message module formats
3780 The affected file is irssi/src/silc/core/silc-channels.c.
3782 * The router did not save the channel mode the server announced.
3783 Affected file silcd/packet_receive.c.
3785 * Fixed a possible crash in INFO command in server. If the
3786 server did not provide the server info it crashed. Affected
3787 file silcd/command.c.
3789 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * Fixed the GETKEY command in the server to check also the
3792 global list. Otherwise the GETKEY would not work correctly
3793 in normal SILC server. Affected file silcd/command.c.
3795 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Fixed GETKEY crash, it crashed if the command did not succseed.
3799 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3802 is now real and not just an macro interface to GMP.
3804 Removed the entire GMP from the source tree and imported new
3805 NSS MPI library instead. Reason for removing GMP is that it is
3806 extremely large and compiles extremely slow. The NSS MPI
3807 is only a few files and compiles in less than 10 seconds.
3808 The speed is also about the same as GMP. The MPI is imported
3809 to lib/silcmath/mpi.
3811 If the system has GMP installed we will still use the GMP.
3812 If it is not then the NSS MPI will be compiled.
3814 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3816 * Merged a long nickname (127 characters long) crash bugfix from
3817 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3819 * Merged a freed memory reference bugfix from Irssi CVS tree.
3820 Affected file irssi/src/core/commands.c.
3822 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Added the server's public key sving and verification to the
3825 server when performing the SKE. This was missing and the
3826 remote server's (or router's) public key was accepted without
3827 checking whether we have it previously or trust it at all.
3828 Affected file silcd/protocol.c.
3830 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Check in the silc_server_timeout_remote if protocol is active
3833 and make sure that the protocol's final callback is called so
3834 that all memory if freed. Affected file silcd/server.c.
3836 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3838 * silc_server_whois_send_reply crashed the server if the nickname
3839 was 127 characters long. Affected file silcd/command.c.
3841 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Added sanity check to the silc_server_new_client. If the hostname
3844 is provided inside username then check that the provided hostname
3845 really is the same as the resolved one. If the hostname was not
3846 resolved then check it from the public key. Affected file is
3847 silcd/packet_receive.c.
3849 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3850 if the server disconnected us and the connection is not valid
3851 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3853 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3854 the library to the lib/silcutil/silcutil.[ch].
3856 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * Close log file after open. Affected file
3859 lib/silcutil/silclog.c.
3861 * Check whether sock == NULL in silc_client_send_packet and return
3862 if it is. Affected file lib/silcclient/silcclient.c.
3864 * Check rec->entry == NULL in the Irssi SILC Client before
3865 sending the channel message. Affecte file is
3866 irssi/src/silc/core/silc-servers.c.
3868 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3870 * Merged a splitted window bugfix from Irssi CVS tree. The
3871 affected file is irssi/src/fe-text/textbuffer-view.c.
3873 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3874 It did not print nickname.
3876 * Improved the distributions system a bit.
3878 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3881 irssi/src/fe-text/gui-window.c.
3883 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3884 to in-active server. The affected file is
3885 irssi/src/silc/core/client_ops.c.
3887 * Resolve the client in USERS command reply if the entry does
3888 not have username resolved. The affected file is
3889 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3890 command to WHOIS command to really resolve stuff. The USERS
3891 is not used any more in any critical section so WHOIS can
3892 be used even though it might be slower than IDENTIFY.
3894 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3897 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Changed the protocol API a bit more consistent in the
3900 lib/silccore/silcprotocol.[ch].
3902 * Changed the following headers to ROBODoc format:
3904 lib/silccore/silcpayload.h
3905 lib/silccore/silcprotocol.h
3906 lib/silccore/silcsockconn.h
3908 All core library headers are now formatted.
3910 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3912 * Fixed a bug in Irssi SILC client; do not show that you are
3913 server/router operator if you really are not. Affected file is
3914 irssi/src/silc/core/client_ops.c.
3916 * Renamed silc_command_free_payload to silc_command_payload_free.
3917 Affected file lib/silccore/silccommand.h
3919 * Added silcmath.h to include the prototoypes of various routines
3920 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3923 * Changed the following headers to ROBODoc format:
3925 lib/silccore/silcchannel.h
3926 lib/silccore/silccommand.h
3927 lib/silccore/silcid.h
3928 lib/silccore/silcidcache.h
3929 lib/silccore/silcmode.h
3930 lib/silccore/silcnotify.h
3931 lib/silccore/silcpacket.h
3932 lib/silcmath/silcmath.h
3934 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3936 * Added checking to the server code not to start the server if
3937 ciphers and stuff are not configured properly. Affected files
3938 silcd/serverconfig.[h] and silcd/server.c.
3940 * Changed the layout of the header files of the public interfaces
3941 in the SILC libraries. The new layout supports ROBODoc
3942 documentation tool (and some others) so that it is easy to create
3943 a library reference manual. All the other headers and source
3944 code must still follow the CodingStyle document. Also source
3945 code must not include these ROBODoc stuffs, only the headers.
3946 Furthermore, all public interface headers must now be named
3947 by using `silc' prefix, example: silcapi.h, silccipher.h.
3948 Some files were renamed due to this. All the other headers
3949 must not be used as public interfaces. I will update the
3950 CodingStyle document later. Changed following headers, so far:
3952 lib/silcclient/silcapi.h
3953 lib/silccore/silcauth.h
3954 lib/silccore/silcprivate.h
3955 lib/silccrypt/silcdh.h
3957 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Removed silc_client_packet_send_flush from the client library
3962 as it is not needed. Affected file lib/silcclient/client.[ch].
3964 * Added printing of message of unresolved authentication method
3965 to the Irssi SILC client. Added it to the module formats.
3966 Removed the same message from the client library.
3968 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Added new distribution feature, DISTLABEL. Every distribution
3971 can define own preprocessor label that can be used in the
3972 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3973 file distributions, acconfig.h.pre and prepare.
3975 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3977 * Added Makefile.defines_int to include the actual definitions
3978 for Makefile.defines.in. Tested the new distribution system,
3979 created distributions and tested installation.
3981 * Added AWAY message printing to the Irssi SILC client. Added
3982 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3984 * Added SCONNECT command to call the SILC's CONNECT command.
3985 Cannot use CONNECT directly since Irssi uses that internally.
3986 Affected file irssi/src/silc/core/silc-servers.c.
3988 Added ACTION local command. It is same as ME command but takes
3989 the channel as mandatory argument.
3991 Rewrote some of the Irssi's help files to suite for SILC
3994 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3996 * Added Makefile.defines[.in] that should for now on be included
3997 in all Makefile.am file in the source tree. That file includes
3998 all common compilation definitions for SILC source tree.
4000 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Minor changes to the ./prepare script to change the package
4003 name according the distribution name to the configure.in.
4005 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Created new distribution system. Added file `distributions'
4008 that defines all the distributions that can be created out of
4009 the SILC source tree. The ./prepare script now reads that
4010 file to determine how to prepare the distributions. The
4011 first argument to the ./prepare is the name of the distribution
4012 and second is the version of the distribution. If given
4013 without arguments it creates the default (toolkit) distribution
4014 with the default version (defined in ./prepare).
4016 All Makefile.am files that are subject to the distributions
4017 are now named as Makefile.am.pre. These are ./Makefile.am
4018 and lib/Makefile.am. Others may be changed later.
4020 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Added invite list, ban list, some key management and connection
4023 error message printing to module formats in the Irssi SILC client.
4025 * Added new silc_client_set_away_message to set the away message
4026 that is back to the person who sent private message. The
4027 affected file lib/silcclient/silcapi.h and the
4028 lib/silcclient/client_prvmsg.c.
4030 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Fixed the private message sending in the Irssi SILC client,
4033 added local command KEY to the Irssi SILC client.
4035 Added key management and key agreement message formats to the
4036 irssi/src/fe-common/silc/module-formats.[ch].
4038 Added USERS (alias WHO) printing, server/router operator
4039 indication and LIST command printing to the module formats.
4041 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Fixed channel joining notify handling, cumode notify handling
4044 from Irssi SILC client.
4046 * Added SILC specific module-formats to the Irssi SILC client so
4047 that SILC specific message hilighting, colors etc is possible.
4048 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4050 Added channel mode, channel user mode, actions, notices,
4051 whois and whowas printing to the the module-formats.c.
4053 * Fixed a bug in channel deletion in the server. The channel
4054 is not left to the cache even if the channel founder auth mode
4055 is set when there are no users anymore on the channel. Affected
4056 file silcd/server.c.
4058 * The silc_net_localhost now resolves the entire hostname including
4059 the domain name. Affected file lib/silcutil/silcnet.c.
4061 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Changed the ask_passphrase client operation to be ascynchronous.
4064 It has now a completion callback and a context that the
4065 application must call after it has got the passphrase from
4066 the user. Affected files lib/silcclient/silcapi.h,
4067 lib/silcclient/protocol.c, lib/silcclient/command.c and
4070 Added SilcAskPassphrase callback that the application calls
4071 to deliver the passphrase to the library.
4073 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4074 The public key verification and especially a certificate
4075 verification is asynchronous procedure.
4077 Added new SILC_SKE_STATUS_PENDING status to indicate the
4078 request is pending and a callback will be called to finalize
4081 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4082 indicate that remote end did not send its public key (or
4083 certificate), even though we require it. Added check for this
4084 condition in the SKE. This was a security bug, now fixed.
4086 Defined new SilcSKEVerifyCbCompletion callback that is called
4087 when the verification process is completed.
4089 The affected files lib/silcske/silcske_status.h and
4090 lib/silcske/silcske.[ch].
4092 * Changed the verify_public_key client operation to be async
4093 as well. Defined SilcVerifyPublicKey callback that is used to
4094 indicate the success of the public key verification process.
4096 Changed the server and client to use the new async client
4099 * Changed the Irssi SILC client's internal scheduler to be called
4100 twice as many times as it used to be. As a result the client
4101 should be a bit faster now. Affected file is
4102 irssi/src/silc/core/silc-core.c.
4104 * Added support to Irssi SILC client of asynchronous public key
4105 verification and passphrase inquiry. Affected file is
4106 irssi/src/silc/core/silc-core.c.
4108 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4110 * Do not say "You have left channel %s" in client library.
4111 Moved it to the application. Affected files are
4112 lib/silcclient/command.c and silc/client_ops.c.
4114 * Fixed silc_client_get_clients. Command context was not
4115 duplicated and was freed memory in the callback. Affected
4116 file lib/silcclient/idlist.c.
4118 * Do not say "you are now talking..." on JOIN command in the
4119 client library. The appliation must handle it.
4121 * Do not say ".. changed topic to" in command reply in the
4122 client libary. The application must handle it.
4124 * Fixed TOPIC command sending in the client library.
4126 * Fixed a memory leak in silc_client_command_free in the file
4127 lib/silcclient/command.c.
4129 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4131 * Imported a modified version of Irssi client to the source tree.
4132 The Irssi will be used to create a new client called
4133 Irssi SILC. Imported to irssi/.
4135 Added silc_core_init_finish function to the Irssi. Affected
4136 file irssi/configure.in.
4138 A lot changes in the Makefile.ams around the irssi tree.
4140 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4142 * Do not rehash if the new size is same as the old size of the
4143 hash table, in the silc_hash_table_rehash*. The affected file
4144 lib/silcutil/silchashtable.c.
4146 * Replaced hash_table_del_by_context calls from the server
4147 (when channel->user_list and client->channels) to the
4148 hash_table_del as it is sufficient and faster.
4150 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4152 * Added silc_hash_table_list, silc_hash_table_get and the
4153 SilcHashTableList structure to provide an alternative way to
4154 traverse the hash table. The affected files are
4155 lib/silcutil/silchashtable.[ch].
4157 * Changed the server's idlist routines to use the hash table
4158 routines to optimize the code.
4160 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Replaced the client entry's `channel' list and channel entry's
4163 `user_list' list to hash tables for optimized lookup. Changed
4164 the code to use the hash table interface around the code.
4165 Affected file lib/silcd/idlist.[ch].
4167 * Added `auto_rehash' boolean argument to the function
4168 silc_hash_table_alloc to indicate whether the hash table should
4169 auto-rehash when it thinks is appropriate time. It will
4170 increase the hash table size if the there is twice as much
4171 entries in the table than the size of the table, and will
4172 decrease the size if there are twice as less entries than
4173 the size of the table.
4175 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4179 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * silc_idcache_purge_by_context deletes the entry now by context
4182 as it is supposed to do. Affected file lib/silccore/idcache.c.
4184 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4185 client is not anymore valid (WHOWAS givens the info) and not
4186 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4188 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * Removed the `data' and `data_len' arguments from the ID Cache
4191 interfaces and added `name' argument. ID Cache does not handle
4192 anymore the binary data only a names associated with given ID.
4194 * When hashing a Client ID with silc_hash_id the entire ID is
4195 not hashed anymore, instead only the hash of the Client ID is
4196 hashed. This way we can access the Client ID from the cache
4197 with Client ID but with the hash of the ID (which is a hash of
4198 the nickname) as well without any difference in performance.
4200 Added also silc_idcache_find_by_id_one_ext to do one on one
4201 searching when we have the actual ID. Added also function
4202 silc_hash_client_id_compare. The affected files are
4203 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4205 * When hashing the name associated with a ID it is always done
4206 in lowercase. This way we can access the cache without worrying
4207 about case-sensitivity, even though, for example nicknames are
4210 * Fixed a bug in server with channel message sending. It put
4211 wrong ID type as destination ID. The affected file
4212 silcd/packet_send.c.
4214 * silc_idcache_del_by_context now deletes from all hash tables
4215 by context. Affected file lib/silccore/idcache.c.
4217 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4219 * Changed the client library to use the new ID Cache interface.
4220 Changes around the source tree.
4222 * Added silc_hash_table_rehash_ext to rehash with specific
4223 hash function. Affected file lib/silcutil/silchashtable.[ch].
4225 * Added silc_hash_string_compare to compare two strings in the
4226 hash table. Affected file lib/silcutil/silcutil.[ch].
4228 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Added new function silc_idcache_del_by_context into the
4231 lib/silccore/idcache.[ch].
4233 * Changed the server's ID list routines to use the new ID Cache
4234 interface. Changes around the source tree.
4236 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Added silc_hash_table_del[_by_context]_ext functions in to the
4239 lib/silcutil/silchashtable.[ch].
4241 Removed silc_hash_table_find_all* routines and added new
4242 silc_hash_table_find_foreach to replace them.
4244 Added silc_hash_table_replace_ext function as extended
4245 replacing function. Separated the simple hash table interface
4246 from the extended hash table interface in the file
4247 lib/silcutil/silchashtable.h.
4249 * Fixed minor bugs and changed it to use some of the new
4250 hash table functions in lib/silccore/idcache.c
4252 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4254 * Added new function silc_hash_table_find_all to return all keys
4255 in the hash table by the specified key. As the hash table is
4256 collision resistant it also makes it possible to have several
4257 duplicate keys in the hash table. This function may be used to
4258 find all of the keys from the hash.
4260 Added user_context arguments to the SilcHashFunction,
4261 SilcHashCompare and SilcHashDestructor to deliver user specified
4264 Added new fuctions silc_hash_table_find[_all]_ext to do
4265 extended lookup with specified hash and compare functions and
4266 specified user contexts.
4268 Added new function silc_hash_table_add_ext to add the key
4269 with specified hash function and user context.
4271 Added new function silc_hash_table_foreach to traverse all
4272 entrys in the hash table. Added SilcHashForeach callback
4275 Added new function silc_hash_table_del_by_context to delete
4276 the entry only if the context associated with the key matches.
4278 Affected files are lib/silcutil/silchashtable.[ch].
4280 * Removed silc_hash_[server/client/channel]_id and added just
4281 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4282 silc_hash_id_compare to compare two ID's using as the hash table
4283 comparison function. Added also silc_hash_data to hash
4284 binary data and silc_hash_data_compare to compare it.
4286 * Removed silc_idlist_find_client_by_hash as it is not needed
4287 anymore. Affected file silcd/idlist.[ch].
4289 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4290 to use internally the SilcHashTable. The new ID Cache is a lot
4291 faster than the old one. Some of the ID Cache interface was also
4292 rewritten and obsolete and stupid functions were removed.
4294 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Added entry_count field to the SilcHashTable to keep the number
4297 of the entries in the table. Implemented the function
4298 silc_hash_table_rehash. Added new function
4299 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4301 Fixed a minor bug in silc_hash_table_free.
4303 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4304 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4305 into the lib/silcutil/silcutil.[ch].
4307 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * Implemented a collision resistant hash table into the
4310 lib/silcutil/silchashtable[ch]. See the header and the source
4311 for the SilcHashTable API.
4313 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4315 * Merged dotconf version 1.0.2 into lib/dotconf.
4317 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Do not compile anything in lib/silcsim/* if the SIM support
4320 is not enabled. The tree should now compile without problems
4323 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Compiled the SILC under cygwin. Compiled and tested briefly
4326 without problems. More tests needed. The SIMs didn't compile
4329 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4331 * Fixed possible crash in silc_get_username in the
4332 lib/silcutil/silcutil.c.
4334 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4336 * Fixed a va_arg in silc/client_ops.c.
4338 * Oops, RC5 routines were named AES and caused some problems
4339 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4341 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Added new SilcIDIP structure into the lib/silccore/id.h and
4344 replaced the old `ip' fields from all SILC ID's to that type.
4345 This is a step towards IPv6 support.
4347 The silc_id_get_len takes now the ID as an extra argument.
4348 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4349 both IPv4 and IPv6 based ID's.
4351 The affected files are lib/silccore/id.[ch] and other files
4352 around the tree using these routines.
4354 * Removed the ID length arguments in server from various
4355 silc_server_send_notify_* routines -> they are not needed
4358 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Fixed memory leak in silc_encode_pem_file in the file
4361 lib/silcutil/silcutil.c.
4363 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Check minor version as well in the SKE. Affected files are
4366 silcd/protocol.c and lib/silcclient/protocol.c.
4368 * Added --identifier option to the server so that an identifier
4369 can be when creating the public key for the server. Affected
4370 file is silcd/silcd.c.
4372 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4373 lib/silccrypt/silcpkcs.c.
4375 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Register default ciphers and stuff when using -C option with
4378 the server. Affected file sildc/silcd.c.
4380 * Put back the servers public key filename format, it is better
4381 than the new one. For now, the client keys are saved with the
4382 new filename format. The affected file silc/client_ops.c.
4384 * Implemented the Cipher API for the rest of the ciphers that
4385 did not implement it or implemented it the wrong way.
4387 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Register default ciphers and stuff when using the -S option
4390 in the client. Affected file silc/silc.c. Same also when
4391 creating new key pair with -C option.
4393 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Fixed the silc_verify_public_key client operation function to
4396 save the public keys differently. The fingerprint is now
4397 used as filename and not the hostname. This way also the
4398 client keys are saved uniquely and not with hostnames. The
4399 affected file is silc/client_ops.c.
4401 * Trimmed the silc_hash_fingerprint function to remove extra
4402 whitespaces from the end of the fingerprint. The affected
4403 file is lib/silccrypt/silchash.c.
4407 * Added silc_cipher_register_default function to register all
4408 default ciphers. It can be used when configuration files
4409 does not exist and the application does not want any specific
4410 ciphers in any specific order.
4412 The SilcDList is now used as silc_cipher_list dynamically
4413 allocated cipher list. Removed the static list all together
4414 and now all ciphers must be allocated to the dynamic list.
4415 The silc_cipher_alloc routine was changed to check only the
4418 All silc_cipher_* routines that used to return int returns
4421 The affected files lib/silccrypt/silccrypt.[ch].
4423 * The same thing was done to silc_hash_* as for silc_cipher_*
4424 routines. Affected files lib/silccrypt/silchash.[ch].
4426 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4427 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4428 Added also silc_pkcs_[un]register[_default] functions.
4429 Removed the data_context from the PKCS API.
4431 * Added silc_hmac_register_default function to register default
4432 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4433 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4434 to unregister all hmacs at once.
4436 * Register the default ciphers, hash functions, PKCSs and HMACs
4437 if client's configuration file does not exist. The affected
4440 * The client did not load the hash functions from the SIM
4441 modules at all. Added support for this. Affected file is
4442 silc/clientconfig.c.
4444 * When decoding public key with silc_pkcs_public_key_decode, check
4445 the supported algorithm only if PKCS are registered. Affected
4446 file lib/silccrypt/silcpkcs.c. The same was done with the
4447 silc_pkcs_private_key_decode.
4449 * Fixed the SILC List routines to keep the list always in order.
4450 It used to change the list's order when traversing the list but
4451 not it preserves the order. Affected file lib/trq/silclist.h.
4453 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Added the client library to use the SilcSocketConnection's
4456 reference counter (by silc_socket_dup) to prevent the bug that
4457 the socket object may be freed underneath async operation.
4459 * The name resolv library checking fixes in the configure.in.pre.
4462 * Created new version of the protocol drafts for future
4463 development. The -03 drafts are the ones that will be changed
4464 in the trunk now and the -02 will remain as they are.
4466 * Send list of CUMODE notifys to the router when announcing
4467 the channel users to the router. Affected file silcd/server.c.
4468 If the router receiving channel founder CUMODE for a channel
4469 that already has channel founder it will send CUMODE notify
4470 to the sender to remove the channel founder rights from the
4471 announced client. Affected file silcd/packet_receive.c.
4473 * The CUMODE notify may now use Server ID as well as the entity
4474 who changes the mode. Updated protocool specs.
4476 * Updated INSTALL and README files.
4478 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4480 * New web pages in the http://silc.pspt.fi. The pages was
4485 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Implemented the [DenyConnectin] config section in the server.
4488 Added silc_server_config_denied_conn to check whether incoming
4489 connection is denied. Affected file silcd/serverconfig.[ch].
4491 * Do not check the ports when checking the incoming configuration
4492 data if the port is 0, meaning any. Affected file is
4493 silcd/serverconfig.c.
4495 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Fixed buffer overflow in silc_string_compare in the file
4498 lib/silcutil/silcutil.c.
4500 * Fixed double free in silc_server_command_leave in the file
4503 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Fixed the version checking in the server. Affected file is
4508 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Fixed the configuration data fetching when accepting new
4511 connections in the server. Affected file silcd/server.c.
4513 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Added `sender_entry' argument to the function
4516 silc_server_packet_relay_to_channel so that we can check
4517 whether some destination actually belongs to the same route
4518 the sender belongs (ie, we must not resend the packet to the
4519 sender). Affected file silcd/packet_send.[ch].
4521 * Added `servername' field to the SilcClientEntry in the server
4522 to hold the name of the server where client is from. Affected
4523 file is silcd/idlist.h.
4525 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Moved the channel message encrypting in the router betwen
4528 router connections from silc_server_channel_message to the
4529 silc_server_packet_relay_to_channel since we want to check
4530 whether we have anybody channel before encrypting anything.
4531 Affected files silcd/packet_[receive/send].c.
4533 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4535 * Fixed the [AdminConnection] server config section to support
4536 multiple entries. Affected file silcd/serverconfig.c.
4538 * Added support into the server to check the validity of the
4539 incoming connection before executing any KE or authentication
4542 * The connection configuration is now saved to the KE and
4543 connection auth protocol contexts and not fetched anymore in
4544 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4546 * The local hosts listenning address and port is also resolved
4547 now when starting the server. We want to have the socket object
4548 to include the real address and port for the listener. Added
4549 new function silc_net_check_local_by_sock into the files
4550 lib/silcutil/silcnet.[ch].
4552 * Fixed a broadcast bug in server -> do not broadcast if we
4555 * Fixed a routing bug. Do not route broadcast packets ever.
4556 Broadcast packets must be processed always and not routed since
4557 they may be destined to some other host than yourself and thus
4558 would get routed without no good reason. Affected file is
4561 * Added function silc_server_config_is_primary_route to check
4562 whether primary router connection has been configured (a router
4563 configuration that we are initiating). If there is not, we
4564 will assume that there is only two routers in the SILC network
4565 and we will use the incoming router connection as our primary
4566 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4568 * Changed the order of the broadcasting. Broadcast _after_ the
4569 packet has been processed not before. Affected file is
4572 * Fixed a [ClientConnection] parsing bug. The port was never
4573 parsed correctly thus resulting to port 0. Affected file
4574 silcd/serverconfig.c.
4576 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4577 argument and did not set the broadcast packet flag. Affected
4578 file silcd/packet_send.c. Fixed same bug in the function
4579 silc_server_send_notify as well.
4581 * If we receive NEW_ID packet for our own ID in the server, ignore
4584 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Removed the nickname from the Private Message Payload.
4589 Updated the code and the protocol specs.
4591 * Updated protocol specs for submitting to the IETF.
4593 * Tweaked the Random Number Generator a bit. Affected file
4594 lib/silccrypt/silcrng.c. Exported a new function
4595 silc_rng_[global]_add_noise which can be used to add more
4598 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Do not parse packets with different timeout when protocol
4601 is active -> may cause problem with rekey. Affected file
4604 * When server receives signoff notify it must not create
4605 new channel key if the client is on any channels since the
4606 sender of the signoff notify will create it.
4608 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Added printing of error messages during SKE protocol from the
4611 failure packet sent by server during SKE. Affected file
4614 * Removed the client's failure_callback handling with timeout
4615 and handle it immediately when received.
4617 * The SKE library returned wrong type in SUCCESS and FAILURE
4618 packets. They must be 32 bit MSB not 16 bit MSB.
4620 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Ok, rewrote the logic of the re-key and now it seems to work.
4623 I tested it on high traffic with frequent re-keys without
4624 problems. Added hmac_receive (and renamed hmac to hmac_send)
4625 in SilcClientConnection in lib/silcclient/client.h and
4626 in SilcIDListData in silcd/idlist.h. Also, removed the
4627 SilcPacketParserContext's cipher and hmac fields as they are
4628 not needed anymore and actually caused some problems when
4629 the ciphers and hmac's changed underneath the packet parser.
4631 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * If re-key protocol is active then process the incoming packets
4634 synchronously since we must assure that icoming packets encrypted
4635 with the old key is processed before the new keys is set to
4636 use. This is true other packets than for REKEY packets.
4637 Affected file silcd/server.c. The same was done to client library
4638 as well, affected file lib/silcclient/client.c.
4640 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Fixed bug in client and server to accept the force send if
4643 the packet is send from silc_[server/client]_packet_process
4644 function. Otherwise the packets are never delivered, oops.
4646 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4648 * Disable force sending of packets when REKEY protocol is active.
4649 We must assure that no packet is sent directly when rekey is
4650 performed. All packets must be sent through packet queue.
4651 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4652 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4653 function is silc_[server/client]_packet_send_real to check
4656 * Replaced the SIM paths from example config files to
4657 /usr/local/modules. Also, make install creates now
4658 /usr/local/silc/logs directory to hold all the SILC server
4661 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Made the configure.in.pre work on Solaris. Patch by salo.
4665 * Made all ciphers compatible with non-x86 machines. Defined
4666 CBC mode macros into lib/silccrypt/ciphers_def.h.
4668 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Fixed the make install.
4672 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * When MAC computation fails the silc_packet_decrypt returned 0
4675 even though it was supposed to return -1. Fixed this. The
4676 affected file is lib/silccore/silcpacket.c.
4678 * Do not replace the config files in /etc/silc (in make install)
4679 if they already exist. Affected file ./Makefile.am.
4681 * Do not send re-key packets immediately but through packet queue.
4682 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4684 * Changed silc_net_check_host_by_sock to return FALSE if the
4685 IP/DNS could not be resolved. Though, it returns the IP address
4686 now even if it could not resolve it (but returns also FALSE).
4687 Affected file lib/silcutil/silcnet.[ch].
4689 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Added silc_pkcs_decode_identifier to decode the public key's
4692 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4693 Added also silc_pkcs_free_identifier. Added also new context
4694 SilcPublicKeyIdentifier.
4696 * Added -S option to the silc client. It is used to dump the
4697 contents of the specified public key file.
4699 * Changed the PKCS api to return the public key length when
4700 setting the public key.
4702 * Fixed a fatal bug in the public and private key file loading.
4703 Affected file lib/silccrypt/silcpkcs.c.
4705 * Execute the packet parsing for client with zero (0) timeout
4706 if the protocol is active. Affected file silcd/server.c.
4708 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * Made the key generation options to the silcd program. Added
4711 -C option, equivalent to client's option.
4713 * Added new [ServerKeys] config section to the server. It
4714 configures the server's public and private key.
4716 * Defined generic Public Key Payload into the protocol
4717 specification to send specific type of public keys and
4720 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4721 public key or certificate.
4723 * Implemented the GETKEY command to the server and to the
4724 client library and on user interface.
4726 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4728 * Made preliminary `make install' work.
4730 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Added SilcServerRekey context into silcd/idlist.h.
4734 * Added the PFS support as defined in the specification to the
4735 SKE protocol. Affected files lib/silcske/*.c.
4737 * Added `ske_group' field to the SilcServerRekey context to hold
4738 the number of the SKE group that is used with PFS in re-key.
4739 Affected file silcd/idlist.h.
4741 * Added PFS re-key support to the server. Affected file is
4744 * Added silc_protocol_cancel to cancel execution of the next
4745 state of the protocol. Affected file is
4746 lib/silccore/silcprotocol.[ch].
4748 * Added the re-key support with and without PFS to the client
4749 library. Re-key is performed once in an hour, by default.
4751 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4752 Added silc_client_rekey_callback and silc_client_rekey_final.
4753 Affected files are lib/silcclient/protocol.[ch] and
4754 lib/silcclient/client.[ch].
4756 * Removed the `hmac_key' and `hmac_key_len' fields from the
4757 SilcClientConnection structure; not needed. Affected file is
4758 lib/silcclient/client.h.
4762 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4764 * Do not ask whether user wants to use the negotiated private key
4765 for private messages, just use it. Affected file is
4766 silc/local_command.c.
4768 * Added `send_enc_key' and `enc_key_len' fields to the
4769 SilcIDListData structure since they are needed in the re-key
4770 phase. Affected file is silcd/idlist.[ch].
4772 * Implemented the simple re-key protocol into the server.
4773 Affected files silcd/server.c and silcd/protocol.[ch]. The
4774 re-key will be performed once in an hour, by default.
4776 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4777 Added silc_server_rekey, silc_server_rekey_callback and
4778 silc_server_rekey_final.
4780 * Removed Tunneled flag from the protocol. Updated the code
4781 and the specifications.
4783 * Adde `pfs' field to the SilcIDListData to indicate whether
4784 the PFS is to be performed in the re-key. Affected file is
4787 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4790 int64 of at least the xintXX size. If void * is less that 4
4791 bytes uint32 * will be used. Defined bool as boolean.
4793 * Changed _ALL_ unsigned long and unsigned int to uint32,
4794 unsgined short to uint16 in the source tree.
4796 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4797 not handle clients that has entry->data.registered == FALSE.
4798 They are not in the network anymore. Affected file is
4801 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4803 * Implemented the sending of the SERVER_SIGNOFF notify in the
4804 server. Affected file is silcd/server.c.
4806 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4807 Added also silc_notify_payload_encode_args into the
4808 lib/silccore/silcnotify.[ch].
4810 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4811 Affected file silcd/packet_receive.c.
4813 * Implemented the SERVER_SIGNOFF notify handling in the client
4814 library. Affected file lib/silcclient/client_notify.c. Also,
4815 implemnted the printing of the SERVER_SIGNOFF info to the
4816 application. Affected file silc/client_ops.c.
4818 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4819 if the deleting was successful. Affected file silcd/idlist.[ch].
4821 * Added support for public key authentication in the connection
4822 authentication protocol in the client library. Affected file
4823 lib/silcclient/protocol.c.
4825 * Changed the server's silc_idlist_get_clients_by_* interface
4826 to support already allocated array so that new entries may be
4827 added to pre-allocated array. Affected file silcd/idlist.[ch].
4828 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4829 and command replies.
4831 * All command reply functions in the server now calls the
4832 pending command callback even if error occured. This way the
4833 error will be delivered to the client as well. Affected files
4834 silcd/command.c and silcd/command_reply.c.
4836 * Fixed INFO command to return local server's info if no server
4837 was provided. Affected file lib/silcclient/command.c.
4839 * Removed RESTART command for good. Updated the code and the
4842 * Rewrote parts of the task system. It is a bit simpler now.
4843 Removed unsued task priorities. The affected files are
4844 lib/silcutil/silctask.[ch].
4846 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * Moved the USERS printing from the library to the application.
4849 Affected files lib/silcclient/command.c and silc/client_ops.c.
4851 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4855 * Added channel key re-key support. The re-key is perfomed
4856 only by the router and is done once in an hour. Added `rekey'
4857 field to the SilcChannelEntry in the server. Affected files
4858 silcd/server.c and silcd/idlist.h.
4860 * Added silc_task_unregister_by_context into the file
4861 lib/silcutil/silctask.[ch].
4863 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Added SILC_UMODE_GONE mode to indicate when the client is not
4866 present in the SILC network. Added also support to the local
4867 command AWAY that will set this mode. Added support of showing
4868 "xxx is gone" in WHOIS command. The USERS command shows the
4869 gone status as well.
4871 * Fixed setting server and router operator privileges in the
4872 server's UMODE command. Affected file silcd/command.c.
4874 * Merged the SKE KE1 and KE2 payloads into one payload. The
4875 new KE payload is equivalent to the old KE2 payload.
4877 Cleaned up the SKE Start Payload parsing. It now uses the
4878 simple buffer unformatting to do the parsing. A lot faster
4881 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4882 to the SKE that is used to indicate whether both of the SKE
4883 parties should perform authentication. By default only the
4884 responder performs authentication. By setting this flag also
4885 the initiator must do authentication. By default it is unset
4886 since in normal SKE case, client to server connection, only
4887 the responder should do authentication. When doing SKE between
4888 two clients both should perform authentication. Updated the
4889 code and the protocol specs.
4891 * A little fix to IDENTIFY command in the server. Search the
4892 client first by hash not nickname. Affected file is
4895 * Fixed the silc_client_close_connection to support closing
4896 the client to client connections wihtout deleting too much
4897 data. Affected file lib/silcclient/client.c.
4899 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4900 are received if protocol used to be active but is not anymore
4901 the application would crash due to NULL pointer dereference.
4902 Affected files silcd/server.c and lib/silcclient/client.c.
4904 * Added `hash' field to the SilcClientConnection to include
4905 the hash function negotiated in the SKE protocol.
4907 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4908 to set the channel founder authentication data. A client can
4909 claim the founder rights later by providing the authentication
4910 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4911 This way the channel founder can regain the channel founder
4912 privileges even it is left the channel. This works only on
4913 local server and the client must be connected to the same
4914 server to be able to regain the founder rights. Updated the
4915 protocol specs accordingly.
4917 Added support to the CMODE command in the client to set the
4918 founder auth data. Read the README to see how to set it.
4920 Added support to the CUMODE command to claim the founder
4921 rights. Read the README to see how to do it.
4923 Added support for the founder authentication to the Channel
4924 Entry in the server. Affected file silcd/idlist.h.
4926 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4927 server's CMODE command. Affected file silcd/command.c.
4929 * Added the following new functions into lib/silccore/silcauth.[ch]:
4930 silc_auth_get_method and silc_auth_get_data.
4932 * The server now saves the remote hosts public key to the
4933 SilcIDListData pointer. Affected file silcd/protocol.c.
4935 * The normal server now does not remove the channel entry from
4936 the cache if the founder authentication data is set. It used
4937 to remove it if the founder was the last one on the channel on
4938 the server and left the channel. The auth data is saved and
4939 if the channel is re-joined later the old entry is used with
4940 the old auth data. Affected files silcd/command_reply.c and
4943 * Removed the `pkcs' field from the SilcIDListData structure
4944 in the server; it is not used. Affected file silcd/idlist.h.
4946 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Fixed packet processing on slow links. Partial packets were
4949 never re-processed because the incoming data buffer was cleared
4950 by the application. Application must not directly clear the
4951 sock->inbuf, the packet processing routines handle it. Fixed
4952 this in client library and in server.
4954 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Fixed the WHOIS and IDENTIFY send reply function to really
4957 check whether to send list or just one entry. Affected file
4960 * Cleaned up the LEAVE command's channel key distribution. The
4961 affected file silcd/command.c.
4963 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4964 can enforce the channel mode as well. In that case the ID
4965 includes the ID of the server. The code now enforces the
4966 mode change if the router have different mode than the server.
4968 * The notify client operation with CMODE_CHANGE notify can now
4969 return NULL client_entry pointer if the CMODE was not changed
4970 by client. Application must check for this.
4972 * Added <Server ID> argument to INFO command to support server
4973 info fetching by Server ID.
4975 * Added silc_server_announce_get_channel_users to get assembled
4976 packets of channel users of the specified channel. Affected
4977 file silcd/server.[ch].
4979 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4980 was freed underneath the ID Cache.
4982 * Re-announce clients when the server received CHANNEL_CHANGE
4983 notify from the router. Affected file silcd/packet_send.c.
4985 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4988 crashed since it did not handle the fact that there is no cipher
4989 called "3" and didn't check the error condition. Now fixed.
4991 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4992 flag. It can be used to send message requests.
4994 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4996 * Implemented the RESTART command in the client.
4998 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4999 notice type messages. Added notice printing to the user
5002 * The channel keys are not re-generated if the channel's mode
5003 is PRIVKEY, ie private key on the channel exists. Affected
5004 files silcd/server.c and silcd/command.c.
5006 * Fixed a little bug in channel message delivery when channel
5007 private keys are set in the server. Affected file is
5008 silcd/packet_send.c.
5010 * Changed the setting on channel->on_channel = TRUE from the
5011 silc_client_save_channel_key to the JOIN command reply. The
5012 key payload is not received if the private channel key is set.
5013 Affected file lib/silcclient/command_reply.c and the
5014 lib/silcclient/client_channel.c.
5016 * When the CMODE_CHANGE notify is sent and the channel private
5017 key mode is removed the channel key must be re-generated in
5018 other cells as well. Added this support for the router in the
5019 silcd/packet_receive.c.
5021 * Added new local command NOTICE to send notice message on
5022 channel. Affected file silc/local_command.[ch].
5024 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Added new local command ME to the client. It is used to send
5027 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5028 some action. Affected file silc/local_command.[ch].
5030 * Changed channel_message and private_message client operations
5031 to deliver the message flags to the application. Added also
5032 the `flags' arguments to the silc_client_send_channel_message
5033 and silc_client_send_private_message functions. Affected file
5036 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Redefined the Private Message Payload to support private message
5039 keys and to support the new private message flags. Updated
5040 the protocol specs. Flags makes it possible to have for example
5041 CTCP style messages.
5043 * Added new type SilcPrivateMessagePayload and defined an API
5044 for it in the lib/silcclient/silcprivate.[ch].
5046 * Tested private message private keys successfully. Tested the
5047 private message key set, unset and list commands with the new
5050 * Redefined the Channel Message Payload to include the channel
5051 message flags (equal with private message flags) to support
5052 for example CTCP style messages.
5054 * Defined some of the message (for channel and private message)
5055 flags. Updated the protocol specs and added the flags to the
5056 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5058 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5060 * Added SilcKeyAgreementStatus type to the key agreement routines
5061 to indicate the current status and error if one occured.
5062 The status types are defined in the lib/silcclient/silcapi.h.
5064 * Added new local command KEY that is used to set and unset private
5065 keys for channels, set and unset private keys for private messages
5066 with remote clients and to send key agreement requests and
5067 negotiate the key agreement protocol with remote client. The
5068 key agreement is supported only to negotiate private message keys,
5069 it currently cannot be used to negotiate private keys for channels,
5070 as it is not convenient for that purpose.
5072 * Fixed a minor pending callback setting bug in the function
5073 silc_client_get_client_by_id_resolve, now the function works.
5074 Affected file lib/silcclient/idlist.c.
5076 * Added function silc_net_get_local_port to get local bound
5077 port by socket. Added to lib/silcutil/silcnet.[ch].
5079 * Added `sockets' and `sockets_count' fields to the SilcClient
5080 object. They hold the sockets of the listenning sockets in
5081 the client. Listenning sockets may be for example the key
5082 agreement server. Affected file lib/silcclient/client.[ch].
5083 Added functions the silc_client_add_socket and the
5084 silc_client_del_socket. They are exported to the application
5087 * Added ~./silc/clientkeys to support other client's public keys.
5089 * Renamed verify_server_key client operation to verify_public_key
5090 and added one argument to indicate the type of the connection
5091 (server, client etc.).
5093 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Added silc_server_connection_auth_request to handle the
5096 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5097 silcd/packet_receive.[ch].
5099 * Added silc_server_send_connection_auth_request into the
5100 silcd/packet_send.c to send the connection auth request packet.
5102 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5105 * Fixed the public key authentication in responder side in the
5106 server. The `auth_data' pointer includes the SilcPublicKey
5107 not the path to the public key. Affected file silcd/protocol.c.
5109 * Implemented the public key authentication in the initiator side
5110 in the server. Affected file silcd/protocol.c.
5112 * Removed the [RedirectClient] config section from the server
5113 configuration. Is not needed and I don't want to implement it.
5115 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5117 * Cleaned up the CMODE command in the server. It now works
5118 correctly and supports all the modes defined in the protocol.
5119 Affected file is silcd/command.c.
5121 * Added `hmac_name' field to the SilcChannelEntry in the server
5122 to hold the default HMAC of the channel. It can be set when
5123 creating the channel (with JOIN command). Affected files
5126 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5127 type to indicate the change of the current cipher and hmac
5128 on the channel. Client can safely ignore the <cipher> argument
5129 (if it chooses to do so) since the CHANNEL_KEY packet will
5130 force the channel key change anyway. The <hmac> argument is
5131 important since the client is responsible of setting the new
5132 HMAC and the hmac key into use.
5134 * Fixed the CMODE command in the client library as well.
5136 * Tested CMODE command in router environment successfully.
5138 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5140 * Show the version of the remote client (or server) when connecting
5141 to the server. It is logged to the log file. Affected file
5142 is silcd/protocol.c.
5144 * Fixed the KILLED notify handling in the client library. The
5145 client must be removed from all channels when receiving the
5148 Also, do not remove the client entry when giving the KILL
5149 command but when the KILLED notify is received.
5151 * Removed silc_idlist_find_client_by_nickname from the server.
5152 Not needed anymore. Affected files silcd/idlist.[ch].
5154 * Implemented the CHANNEL_CHANGE notify type handling to the
5155 server. Affected file silcd/server.c.
5159 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5161 * Added silc_server_send_notify_invite to send the INVITE
5162 notify between routers.
5164 * Implemented the INVITE command correctly to the server.
5166 * Implemented the INVITE notify type handling in the server.
5168 * Implemented the INVITE command to the client library and on the
5171 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Added function silc_server_get_client_resolve to find the
5174 client entry by ID from all ID lists and then resolve it
5175 (using WHOIS) if it cannot be found. Affected file is
5178 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Implemented the BAN command to the client library.
5182 * The JOIN command in the server now checks the invite list
5185 * Changed the silc_command_reply_payload_encode_va and the
5186 silc_command_payload_encode_va to support that if argument is
5187 NULL it ignores and checks the next argument. Affected file
5188 lib/silccore/silccommand.c.
5190 * Added silc_server_send_notify_ban to send the BAN notify
5191 type between routers.
5193 * Chaned the silc_notify_payload_encode to support that if
5194 argument is NULL it ignores and checks the next argument.
5195 Affected file lib/silccore/silcnotify.c.
5197 * Tested ban lists in router environment successfully.
5199 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Implemented BAN command to the server, in silcd/command.[ch].
5203 * Removed the BAN and INVITE_LIST modes from the CMODE command
5206 * Added function silc_string_match to regex match two strings.
5207 Affected files lib/silcutil/silcutil.[ch].
5209 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * Redefined parts of the SilcChannelEntry in the server to support
5212 the new ban and invite lists.
5214 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Redefined the INVITE command. The same command can be used to
5217 invite individuals to the channel but also to manage the invite
5218 list of the channel (to add to and remove from the invite list).
5219 Updated the protocol specs.
5221 * Added new command SILC_COMMAND_BAN that can be used to manage
5222 the ban list of the channel. Updated the protocol specs.
5224 * Removed the channel modes: the SILC_CMODE_BAN and the
5225 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5226 in the CMODE command. The equivalent features are now available
5227 using INVITE and BAN commands. Updated the protocol specs.
5229 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5230 in the network about change in the current ban list. The notify
5231 type is not used by the client.
5233 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5234 support the invite lists.
5236 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Added new function silc_string_regexify that converts string
5239 including wildcard characters into regex string that can
5240 be used by the GNU regex library. Added into the file
5241 lib/silcutil/silcutil.[ch].
5243 Added silc_string_regex_combine to combine to regex strings
5244 into one so that they can be used as one regex string by
5245 the GNU regex library. Added into the file
5246 lib/silcutil/silcutil.[ch].
5248 Added silc_string_regex_match to match two strings. It returns
5249 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5251 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5253 * Imported GNU regex to the soruce tree into lib/contrib.
5254 Fixed some compiler warning from the regex.c.
5256 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Fixed MOTD command in the server to work in router environment.
5260 * Fixed the MOTD command in the client library to support
5261 the server argument in the command.
5263 * Added `nickname_len' argument to the silc_idlist_add_client
5264 in the server, as the `nickname' argument may be binary data
5267 * Added silc_idlist_get_channels to return all channels from
5270 * Implemented LIST command to the server. Affected file is
5273 * Implemented the LIST command to the client library and on the
5276 * Added [<user count>] argument to the LIST command reply.
5277 With private channels the user count is not shown.
5279 * Updated TODO and README.
5281 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5283 * The client entry's data.registered must be TRUE even with
5284 global client entry on global client list. The data.registered
5285 is used to check whether the client is anymore in the network,
5286 for example with WHOWAS command so it must be valid.
5288 * Fixed the WHOWAS command in the server. It now actually works
5289 in router environment. Added function into silcd/command_reply.c
5290 silc_server_command_reply_whowas_save.
5292 * Added silc_idlist_purge function to the silcd/idlist.c
5293 to periodically purge the ID Cache.
5295 * Fixed INFO command in the server. It works now in router
5296 environment. Added <server name> argument to the INFO command
5297 reply. Updated the protocol specs.
5299 * Fixed minor bug in silc_idcache_purge to not purge if the
5300 expire value is zero.
5302 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5303 they were buggy because of the WHOWAS information.
5305 * Fixed local command MSG to handle the async resolving of
5306 the remote client properly. It used to fail the first MSG.
5307 Affected file silc/local_command.c.
5309 * Added `data_len' field to SilcIDCache context.
5311 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * Update TODO. Todo in commands in the server.
5315 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5317 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5318 used by routers as broadcast packet to inform other routers
5319 about the changed user mode.
5321 Implemented the notify handling in the server. Affected file is
5322 silcd/packet_receive.c. Added the function
5323 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5325 * Added new generic Channel Payload and deprecated the New Channel
5326 Payload. The New Channel Payload is now the generic Channel
5329 * Added new argument `mode' to the silc_server_send_new_channel
5330 as it is required in the Channel Payload now.
5332 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5333 and created a new and real SilChannelPayload to represent the
5334 new generic Channel Payload. Implemented the encode/decode
5335 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5337 * Added silc_server_get_client_channel_list to return the list
5338 of channels the client has joined for WHOIS command reply.
5339 Affected file silcd/server.[ch].
5341 * Implemented the channel list sending in the WHOIS command reply
5342 in server and in the client.
5344 Implemented the channel list displaying on the user interface
5345 as well. Affected file silc/client_ops.c.
5347 * Added silc_channel_payload_parse_list to parse list of Channel
5348 Payloads. It returns SilcDList list of SilcChannelPayloads.
5349 Client for example can use this function to parse the list of
5350 channels it receives in the WHOIS command reply. The caller
5351 must free the list by calling silc_channel_payload_list_free.
5352 Affected files lib/silccore/silcchannel.[ch].
5354 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5356 * Added one new argument <user mode> to the WHOIS command reply
5357 to return the mode of the user in SILC. Updated the protocol
5360 Implemented it to the server and client.
5362 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Fixed the mode printing on the user interface on joining.
5365 Affected file silc/client_ops.c.
5367 * Implemented the UMODE command and user modes in general to the
5368 client library and to the user interface.
5370 * Implemented the UMODE command to the server.
5372 * The server now sends UNKNOWN_COMMAND error status if client sends
5373 unknown command. Affected file silcd/command.c.
5375 * All server commands now handle the command identifier the right
5376 way when sending the command reply to the client. The client can
5377 use to identify the command replies with the identifier.
5379 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Added silc_server_get_client_route to resolve the route to
5382 the client indicated by the client ID. Affected file is
5385 * Added silc_server_relay_packet as general function to relay
5386 packet to arbitrary destination. This deprecates functions
5387 like _send_private_message_key, _relay_notify etc. Affected
5388 file is silcd/packet_send.[ch].
5390 Removed silc_server_send_key_agreement,
5391 silc_server_send_private_message_key and
5392 silc_server_packet_relay_notify functions from the file
5393 silcd/packet_send.[ch].
5397 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5398 server. Affected file silcd/packet_receive.[ch].
5400 * Implemented the KILL command to the client. Implemented the
5401 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5402 Affected files lib/silcclient/command[_reply].c and
5403 lib/silcclient/client_notify.c. Implemented the KILL notify
5404 printing in the user inteface.
5406 * Fixed a lot silc_parse_nick memory leaks from the client
5407 library in the file lib/silcclient/command.c.
5409 * Changed the silc_server_send_notify_on_channels's `sender'
5410 argument from SilcSocketConnection to SilcClientEntry to
5411 check the sender as entry and not as connection object and not
5412 to send to the client provided as argument. The affected file
5413 is silcd/packet_send.[ch].
5415 * The notify packets that are destined directly to the client used
5416 to not to be processed by the server. Now changed that and the
5417 server processes all notify packets. After relaying the packet
5418 to the client the notify packet is processed in the server.
5420 * The silc_server_free_client_data now checks whether there is
5421 pending outgoing traffic for the client and purges the data to
5422 the network before removing the client entry.
5424 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5427 an client is killed from the SILC Network. Updated the protocol
5430 Added new function silc_server_send_notify_killed to the
5431 silcd/packet_send.[ch].
5433 * Added function silc_server_packet_relay_notify to relay notify
5434 packets that are destined directly to a client. In this case
5435 the server does not process the notify packets but merely relays
5436 it to the client. Affected file silcd/packet_send.[ch].
5438 Added also silc_server_packet_process_relay_notify to check
5439 whereto relay the notify. Affected file is
5440 silcd/packet_receive.[ch].
5442 * Implemented the KILL command to the server.
5446 * Added the backup schema desgined last fall to the protocol
5447 specs for everyone to see. The specification is in the
5448 *-spec-xx.txt draft and the packet type definitions for the
5449 backup routers is in *-pp-xx.txt draft. Thusly, added also
5450 new packet type SILC_PACKET_CELL_ROUTERS.
5452 * A big security problem in the implementation discovered. The
5453 signoff of an client did not cause new channel key generation
5454 which it of course should've done. The channel keys must be
5455 always re-generated when client leaves (or signoffs) the channel.
5456 The silc_server_remove_from_channels funtion now handles
5457 the channel key re-generation.
5459 * Added `sender' argument to the silc_server_send_notify_on_channels
5460 to not to send the client provided as argument. Affected file
5461 silcd/packet_send.[ch].
5463 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5465 * Implemented OPER and SILCOPER commands into the server and
5468 * Added silc_auth_verify and silc_auth_verify_data to verify
5469 the authentication directly from the authentication payload.
5470 It supports verifying both passphrase and public key based
5471 authentication. Affected file lib/silccore/silcauth.[ch].
5473 * Added `hash' field to the SilcIDListData structure. It is the
5474 hash negotiated in the SKE protocol. Affected file is
5477 * Slight redesigning of the SilcAuthPayload handling routines.
5478 Do not send SilcPKCS but SilcPublicKey as argument.
5480 * Implemented the public key authentication support to the
5481 serverconfig. The public key is loaded from the provided path
5482 and saved as authentication data to void * pointer. Thus,
5483 changed the unsigned char *auth_data to void *auth_data;
5485 * Fixed SHUTDOWN command to send the reply before the server
5486 is shutdown. :) Affected file silcd/command.c.
5488 * Fixed fatal bug in CONNECT command. The hostname was invalid
5489 memory and server crashed. Affected file silcd/command.c.
5491 * Fixed fatal bug in CLOSE command. The server_entry became
5492 invalid but was referenced later in the command. Affected file
5495 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Fixed fatal bug in failure packet handling. Server ignored
5498 the failure and thus crashed when it came.
5502 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5504 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5505 that the command may be executed only once in (about) 2 seconds.
5506 The old SILC_CF_LAG flag is same but allows command bursts up
5507 to five before limiting.
5509 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5510 server code. Various commands now includes the CF_LAG_STRICT
5511 flag to disallow any kind of miss-use of the command.
5513 * Fixed the silc_buffer_unformat to not to allocate any data
5514 if the length of the data is zero. It used to allocate the
5515 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5517 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * Changed the format of AdminConnection configuration section
5520 in the server. Added username of the admin to the format.
5521 Affected files silcd/serverconfig.[ch].
5523 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5524 to return admin configuration data by host, username and/or
5527 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Implemented WHOWAS command to the server. Added the functions:
5531 silc_server_command_whowas_parse,
5532 silc_server_command_whowas_send_reply,
5533 silc_server_command_whowas_from_client and
5534 silc_server_command_whowas_from_server
5536 * Added <Client ID> argument to the WHOWAS command reply. Updated
5537 the protocol specs accordingly.
5539 * Implemented WHOWAS command and command_reply to the client
5542 Implemented the WHOWAS printing on the user interface.
5544 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Added new argument to the WHOWAS command reply, the real name.
5547 It is an optional argument. Updated the protocol specs.
5549 * Added SilcIDCacheDestructor callback that is registered when
5550 the SilcIDCache is allocated. The callback is called when
5551 an cache entry in the ID Cache expires, or is purged from the
5552 cache. Added into lib/silccore/idcache.[ch].
5554 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5555 to destruct the client entries when the cache entry expires.
5556 Other ID Cache's in server and in the client library ignores
5559 * If the ID Cache entry's `expire' field is zero then the entry
5560 never expires. Added boolean `expire' argument to the
5561 silc_idcache_add function in the lib/silccore/idcache.[ch].
5562 If it is TRUE the default expiry value is used.
5564 * Added silc_server_free_client_data_timeout that is registered
5565 when client disconnects. By default for 5 minutes we preserve
5566 the client entry for history - for WHOWAS command.
5568 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5570 * Added support to the server to enforce that commands are not
5571 executed more than once in 2 seconds. If server receives
5572 commands from client more frequently, timeout is registered
5573 to process the commands. Affected file silcd/command.c.
5574 Added new function silc_server_command_process_timeout.
5576 * Changed NICK_NOTIFY handling in client library to check that
5577 if the client's nickname was changed, so there is no need to
5578 resolve anything from the server.
5580 * Removed error printing from the WHOIS and IDENTIFY commands.
5581 If error occurs then it is ignored silently in the client library.
5582 The application, however, may map the received error to
5583 human readable error string. The application currently maps
5584 the NO_SUCH_NICKNAME error to string.
5586 * Made the command status message public to the application. Moved
5587 them from lib/silcclient/command_reply.c to
5588 lib/silcclient/command_reply.h. The application can map the
5589 received command status to the string with the
5590 silc_client_command_status_message function.
5592 * Added check to the server to check that client's ID is same
5593 as the Source ID in the packet the client sent. They must
5596 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Added dist-bzip hook to the Makefile.am to make bzip2
5599 compressed distributions.
5601 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Server now enforces the maximum length for the nickname and
5604 the channel as protocol specification dictates. 128 bytes for
5605 nickname and 256 bytes for channel name.
5607 * Moved the WHOIS printing to the application. The client libary
5608 does not print out the WHOIS information anymore, the application
5609 must do it. Renamed silc_client_command_reply_whois_print to
5610 the silc_client_command_reply_whois_save.
5612 The client's idle time is also sent to the application now, and
5613 the idle is shown on screen.
5615 * Added silc_client_command_reply_identify_save to save the
5616 received IDENTIFY entries.
5618 * Do not check for channel private keys in message sending and
5619 reception if the channel does not have the PRIVKEY mode set.
5620 Affected file lib/silclient/client_channel.c.
5622 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5625 just surfaced after chaning the JOIN procedure.
5627 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * Added silc_client_get_clients_by_list to get client entries
5630 from Client ID list, that is returned for example by JOIN
5631 and USERS command replies. The application should use this
5632 function for example when JOIN command reply is received to
5633 resolve the clients already on the channel (library does not
5634 do that anymore as USERS command reply is not used in the JOIN
5635 procedure anymore). Affected files lib/silcclient/silcapi.h and
5636 lib/silcclient/idlist.c.
5638 * JOIN command reply and USERS command reply returns now SilcBuffer
5639 pointers instead of unsigned char pointers when returning
5640 the client list and mode list.
5642 * Added <Client ID> argument to the JOIN command reply, mainly
5643 for the server to identify for which client the command was
5644 originally sent. Updated protocol specs accordingly.
5646 * Added SilcDlist private_key pointer to the SilcChannelEntry
5647 in the client to support the channel private keys. Affected
5648 file is lib/silcclient/idlist.h.
5650 * Added SilcChannelPrivateKey argument to the function
5651 silc_client_send_channel_message so that application can choose
5652 to use specific private ke if it wants to. If it is not provided,
5653 the normal channel key is used, unless private keys are set.
5654 In this case the first (key that was added first) is used
5655 as the encryption key.
5657 * Implemented the support for channel private key handling.
5658 Implemented the following functions:
5660 silc_client_add_channel_private_key,
5661 silc_client_del_channel_private_keys,
5662 silc_client_del_channel_private_key,
5663 silc_client_list_channel_private_keys and
5664 silc_client_free_channel_private_keys
5666 Affected file lib/silcclient/client_channel.c.
5668 * Added the support for the private keys in the channel message
5669 sending and encryption and in the message reception and
5670 decryption. Affected funtions are
5671 silc_client_send_channel_message and silc_client_channel_message.
5673 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5675 * Added SKE's key verify callback to the client library's
5676 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5678 * Removed the statement that server (or router) must send USERS
5679 command reply when joining to the channel so that the client
5680 knows who are on the channel. Instead, the client list and
5681 client's mode list is now sent in the JOIN command reply to the
5682 client who joined channel. This is better solution.
5684 * Added function silc_server_get_users_on_channel and function
5685 silc_server_save_users_on_channel to the silcd/server.[ch].
5687 * Removed function silc_server_command_send_users from the
5690 * Do not show topic on the client library anymore. The topic is
5691 sent in the command reply notify to the application and the
5692 application must show the topic now.
5694 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Added client searching by nickname hash into the IDENTIFY and
5697 WHOIS commands in the server as they were clearly missing from
5698 them. Affected file is silcd/command.c.
5700 * Fixed a bug in private message receiving in the client library.
5701 The remote ID was freed and it wasn't supposed, now it is
5704 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Minor fix to the channel payload; allocate the data area, as it
5707 needs to be of specific length.
5709 * If the key agreement port is zero then the operating
5710 system will define the bound port. Affected files are
5711 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5713 * Added new function silc_channel_payload_decrypt into the file
5714 lib/silccore/silcchannel.[ch].
5716 * Moved the channel message etc, check from silc_packet_decrypt
5717 to applications. The library calls now a generic
5718 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5719 when the packet is either normal or special. This was done to
5720 allow more wide range of checking that was not allowed when
5721 the code was in library. Now applications can do virtually any
5722 checks to the packet and return to the library the decision how
5723 the packet should be processed. Affected files are
5724 lib/silccore/silcpacket.[ch].
5726 Added silc_server_packet_decrypt_check to the server and
5727 silc_client_packet_decrypt_check to the client library.
5729 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5730 to send with specified source and destination information.
5732 * Channel message delivery between routers was broken after the
5733 channel key distribution was fixed earlier. The channel key
5734 was used be to distributed to other routers as well which is not
5735 allowed by the protocol. Now this is fixed and channel keys
5736 really are cell specific and the channel message delivery between
5737 routers comply with the protocol specification.
5739 * Fixed various commands in server to check also the global list
5740 for the channel entry and not just the local list. The affected
5741 file silcd/command.c.
5743 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5745 * Added assert()s to buffer formatting and unformatting routines
5746 to assert (if --enable-debug) when error occurs. Affected
5747 file: lib/silcutil/silcbuffmt.c.
5749 * Changed to auto-reconnect to check whether the remote host is
5750 router and register the re-connect timeout if it is. It used
5751 to check that whether we are normal server, but router must do
5752 auto-reconnect with another router as well. Affected file
5755 * Removed the [<key len>] option from CMODE command as the cipher
5756 name decides the key length, nowadays. See the defined ciphers
5757 from the protocol specification.
5759 * Added [<hmac>] option to the CMODE command to define the HMAC
5760 for the channel. Added SILC_CMODE_HMAC channel mode.
5762 * Added [<hmac>] option for the JOIN command so that user can
5763 select which HMAC is used to compute the MACs of the channel
5766 * Added Hmac field to the Channel Message Payload. The integrity
5767 of plaintext channel messages are now protected by computing
5768 MAC of the message and attaching the MAC to the payload. The
5769 MAC is encrypted. Now, it is clear that this causes some
5770 overhead to the size of the packet but rationale for this is that
5771 now the receiver can verify whether the channel message decrypted
5772 correctly and also when private keys are set for the channel the
5773 receiver can decrypt the packet with several keys and check from
5774 the MAC which key decrypted the message correctly.
5776 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5777 lib/silccrypt/silccipher.[ch].
5779 * Added silc_hash_len to return the digest length into the
5780 lib/silcrypt/silchash.[ch].
5782 * Rewrote parts of Silc Channel Payload interface in the
5783 lib/silccore/silcchannel.[ch]. The encode function now also
5784 encrypts the packet and parse function decrypts it.
5786 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * Fixed a minor formatting bug in the SKE's key material processing.
5789 It actually might have processed the keys wrong way resulting
5792 * Redefined the mandatory HMAC algorithms and added new algorithms.
5793 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5794 and hmac-md5 truncated to 96 bits. The mandatory is now
5795 hmac-sha1-96. Rest are optional (including the one that used
5796 to be mandatory). Rationale for this is that the truncated HMAC
5797 length is sufficient from security point of view and can actually
5798 make the attack against the HMAC harder. Also, the truncated
5799 HMAC causes less overhead to the packets. See the RFC2104 for
5802 * Added new [hmac] configuration section. The SKE used to use
5803 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5804 is of course wrong. The official names that must be proposed in
5805 the SKE are the ones defined in the protocol specification
5806 (hmac-sha1-96 for example). The user can configure any hmac
5807 using any hash function configured in the [hash] section. At
5808 least, the mandatory must be configured.
5810 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5812 * Added HMAC list to the SKE proposal list. It has now both
5813 hash algorithm list and HMAC list. This makes the protocol
5814 incompatible with previous versions. The SKE now seems to work
5815 the way it is supposed to work, for the first time actually.
5817 * Defined plain Hash algorithms to the protocol specification.
5820 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Implemented support for key agreement packets into the server.
5823 Added functions silc_server_key_agreement and
5824 silc_server_send_key_agreement. Other than these functions,
5825 server has nothing to do with this packet.
5827 * Added support for private message key packets into the server.
5828 Added functions silc_server_private_message_key and
5829 silc_server_send_private_message_key.
5833 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5834 called in the protocol's final callback instead in the END
5835 protocol state. This makes a little more sense and in the same
5836 time in client we can use the same protocol routines for normal
5837 key exchange and to key agreement packet handling as well.
5839 * Added to both client's and server's KE protocol context the
5840 SilcSKEKeyMaterial pointer to save the key material. We will
5841 bring the key material to the protocol's final callback by doing
5842 this. The final callback must free the key material.
5844 * Added SKE's packet_send callback into client's KE protocol
5845 context so that the caller can choose what packet sending function
5846 is used. This way we can use different packet sending when
5847 doing normal SKE when doing key agreement packet handling (in
5848 the key agreement packet handling we do not want to encrypt
5851 * Implemented the responder side of the key agreement routines
5852 in the client. The client can now bind to specified port and
5853 accept incoming key negotiation. The key material is passed
5854 to the application after the protocol is over.
5856 * Implemented the processing of incoming Key Agreement packet
5857 in the client. Added function silc_client_key_agreement to
5860 * Implemented the intiator side of the key agreement routines
5861 in the client. The client can now initiate key agreement with
5862 another remote client. The key material is passed to the
5863 application after the protocol is over.
5865 * Created client_keyagr.c to include all the key agreement
5868 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5869 SILC_TASK_CALLBACK except that it is not static.
5871 * Created client_notify.c and moved the Notify packet handling
5872 from the client.[ch] into that file.
5874 * Created client_prvmsg.c and moved all private message and
5875 private message key routines from the client.[ch] into that file.
5877 * Create client_channel.c and moved all channel message and
5878 channel private key routines from the client.[ch] into that file.
5880 * Changed silc_client_get_client_by_id_resolve to resolve with
5881 WHOIS command instead of IDENTIFY command, in the file
5882 lib/silclient/idlist.c.
5884 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Implemented the SKE's responder side to the Client library.
5888 * When FAILURE is received to the protocol do not trust it
5889 blindly. Register a timeout to wait whether the remote closes
5890 the connection as it should do it, only after that process the
5891 actual failure. This was changed to both client and server.
5893 * Added client_internal.h to include some of the structures
5894 there instead of client.h in lib/silcclient/.
5896 * Added function silc_task_unregister_by_callback to unregister
5897 timeouts by the callback function.
5899 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5901 * Some "Incomplete WHOIS info" errors has been appearing on the
5902 log files. Took away the entry->userinfo check from WHOIS
5903 reply sending. The entry->userinfo is now " " if client did not
5904 provide one. I thought this was fixed earlier but something
5905 is wrong still. Let's see if the error still appears.
5907 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Fixed a minor bug in the login when the channel key is
5910 re-generated in the server. It used to generate the key in
5911 wrong order and thus caused problems in the channel traffic.
5913 * Fixed a minor bug in channel key distsribution after
5914 KICK command. The key was not sent to the router even though
5917 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Added silc_ske_process_key_material_data as generic routine
5920 to process any key material as the SILC protocol dictates. The
5921 function is used by the actual SKE library but can be used by
5922 applications as well. This relates to the private message keys
5923 and the channel private keys since they must be processed the
5924 same way the normal SILC session keys. The protocol dictates
5925 this. Affected files: lib/silcske/silcske.[ch].
5927 Added also silc_ske_free_key_material to free the
5928 SilcSKEKeyMaterial structure.
5930 * Defined silc_cipher_set_key function to set the key for
5931 cipher without using the object's method function. The affected
5932 files: lib/silccrypt/silccipher.[ch].
5934 * Implemented silc silc_client_add_private_message_key,
5935 silc_client_add_private_message_key_ske,
5936 silc_client_del_private_message_key,
5937 silc_client_list_private_message_keys and
5938 silc_client_free_private_message_keys functions in the
5941 Added functions silc_client_send_private_message_key to send
5942 the Private Message Key payload and silc_client_private_message_key
5943 to handle incoming Private Message Key payload.
5945 * Added Cipher field to the Private Message Key payload to set
5946 the cipher to be used. If ignored, the default cipher defined
5947 in the SILC protocol (aes-256-cbc) is used.
5949 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5951 * Removed lib/silcclient/ops.h file.
5953 Redefined parts of the SILC Client Library API. Created new
5954 file silcapi.h that deprecates the ops.h file and defines the
5955 published Client Library API. Defined also private message key
5956 API and channel private key API into the file.
5958 This is the file that the application must include from the
5959 SILC Client Library. Other files need not be included by
5960 the application anymore.
5962 * Added new key_agreement client operation callback and also
5963 defined the Key Agreement library API for the application.
5965 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5968 is used by clients to request key negotiation between another
5969 client in the SILC network. If the negotiation is started it
5970 is performed using the SKE protocol. The result of the
5971 negotiation, the secret key material, can be used for example
5972 as private message key.
5974 Implemented the Key Agreement payload into the files
5975 lib/silccore/silauth.[ch].
5977 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * Redefined ciphers for the SILC protocol. Added some new ciphers
5980 and defined the key lengths for the algorithms. Changed the
5981 code accordingly. The default key length is now 256 bits.
5983 * Fixed SKE key distribution function silc_ske_process_key_material
5984 when the key length is more than 128 bits. The default key
5985 length in SILC is now 256 bits.
5987 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5988 to indicate unsupported algorithm.
5990 * Renamed rijndael.c to aes.c and all functions as well.
5992 * Fixed a long standing channel key setting bug in client library.
5993 Weird that it has never surfaced before.
5995 * Fixed bug in channel deletion. If the entire channel is removed
5996 then it must also delete the references of the channel entry
5997 from the client's channel list as the client's channel entry and
5998 the channel's client entry share same memory.
6000 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6002 * Implemented CONNECT and SHUTDOWN commands in the client.
6004 * Implemented CLOSE command to the client.
6006 * Added the function silc_idlist_find_server_by_name into the
6007 files silcd/idlist.[ch].
6009 Added the function silc_idlist_find_server_by_conn into the
6010 files silcd/idlist.[ch].
6012 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * DIE command was renamed to SHUTDOWN. Updated the both code
6017 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6018 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6020 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6023 * Added function silc_server_create_connection function to create
6024 connection to remote router. My server implementation actually
6025 does not allow router to connect to normal server (it expects
6026 that normal server always initiates the connection to the router)
6027 so the CONNECT command is only good for connecting to another
6030 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6032 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6033 or some other client was kicked from the channel.
6035 Implemented the handling of the notify type to both client
6038 Implemented silc_server_send_notify_kicked to send the KICKED
6039 notify. It is used to send it to the server's primary router.
6041 * Implemented the KICK command into server and client.
6043 * Added `query' argument to the silc_idlist_get_client function
6044 to indicate whether to query the client from server or not if
6047 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6048 to indicate that the client is not channel founder.
6052 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * Removed the rng context from SilcPacketContext structure and
6055 changed that the packet routine uses the Global RNG API.
6057 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Added support for quit message that client can "leave" on the
6060 channel when it quits the SILC. It is ditributed inside the
6061 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6063 Added silc_server_free_client_data that will take the
6064 signoff message as argument.
6066 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6068 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6070 * Updated parts of the protocol specification to keep it up
6073 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6076 payloads in one packet.
6078 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6079 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6080 use now the new List flag.
6082 * Also deprecated the following packet types: REPLACE_ID,
6083 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6085 * Added list support for Notify packet in server.
6087 * Added silc_server_send_notify_channel_change to send the
6088 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6089 the silc_server_send_replace_id.
6091 * Added silc_server_send_notify_nick_change to send the
6092 NICK_CHANGE notify type. Deprecates the function
6093 silc_server_send_replace_id.
6095 * Added silc_server_send_notify_join to send the JOIN notify type.
6096 Deprecates the function silc_server_send_new_channel_user.
6098 * Added silc_server_send_notify_leave to send LEAVE notify type.
6099 Deprecates the function silc_server_send_remove_channel_user.
6101 * Added silc_server_send_notify_cmode and
6102 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6103 types. Deprecates the silc_server_send_set_mode function.
6105 * Added SERVER_SIGNOFF notify type to indicate that server has
6106 quit. This means that all clients on the channel from that
6107 server will drop. This can be also used when netsplit happens.
6109 Deprecated REMOVE_ID packet type since it is not needed anymore
6112 Added silc_server_send_notify_server_signoff to send the
6113 SERVER_SIGNOFF notify type. Deprecates the function
6114 silc_server_send_remove_id.
6116 Added also silc_server_send_notify_signoff to send the
6117 SIGNOFF notify type.
6119 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6120 SILC protocol from this day on. Changed the protocol
6121 specification as well.
6123 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6124 notify type. It is used between routers to notify about
6125 topic changes on a channel.
6127 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6130 * Partly updated the protocol specification to comply with the
6131 changes now made. It is still though a bit outdated.
6133 * The JOIN notify type now takes one extra argument <Channel ID>.
6134 The packet used to be destined to the channel but now the
6135 JOIN type may be sent as list thus it is impossible to
6136 destine it to any specific channel. By adding this argument
6137 it is again possible.
6139 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6141 * Added CREDITS file. The CHANGES and CREDITS file will appear
6142 in the distribution as well.
6144 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6147 types in the server's silcd/packet_receive.c.
6149 * Implemented CMODE and CUMODE to work in router environment.
6151 * Fixed minor encoding and decoding buglet from the
6152 lib/silccore/silcmode.c.
6154 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6157 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6159 * Changed all SilcConfigServer* and silc_config_server* to
6160 SilcServerConfig* and silc_server_config*, respectively.
6163 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6165 * Associated the ID (client or server ID) to the Authentication
6166 Payload to avoid any possibility of forging. Updated the
6167 protocol specification and the code accordingly.
6169 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * The RSA key length is now save to the RsaKey context in the
6172 key generation process in lib/silccrypt/rsa.c. The key length
6173 is now used to figure out the maximum size of the block allowed
6174 to be encrypted/signed.
6176 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6177 is equivalent to the silc_mp_mp2bin but does not allocate any
6180 * Changed silc_mp_mp2bin API to take length argument. If it is
6181 non-zero then the buffer is allocated that large. If zero, then
6182 the size is approximated using silc_mp_sizeinbase, which however
6185 * Created Global RNG API which is global RNG that application can
6186 initialize. After initializing, any routine anywhere in the
6187 code (including library) can use RNG without allocating a new
6188 RNG object. This was done to allow this sort of use of the
6189 RNG in code that has no chance to allocate RNG object. All
6190 applications currently allocate this and many routines in the
6191 library use this. Affected file lib/silccrypt/silcrng.[ch].
6193 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6194 it to use the Global RNG API.
6196 * Defined Authentication Payload into protocol specification that
6197 is used during SILC session to authenticate entities. It is
6198 used for example by client to authenticate itself to the server
6199 to obtain server operator privileges.
6201 Implemented this payload into the lib/silccore/silcauth.[ch].
6202 Implemented also routines for public key based authentication
6203 as the new protocol specification dictates.
6205 Moved definitions of different authentication methods from
6206 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6208 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6209 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6210 silc_pkcs_verify_with_hash functions into the file
6211 lib/silccrypt/silcpkcs.[ch].
6213 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6215 * The client entry's userinfo pointer must be always valid.
6216 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6217 will fail since it requires the userinfo. Now, the userinfo
6218 is allocated as "" if actual userinfo does not exist. Actually,
6219 it must exist and it is totally Ok to drop client connections
6220 that does not announce the userinfo. However, we will make
6221 this workaround for now.
6223 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6224 to return the remote port by socket.
6226 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6228 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6229 SILC_SERVER_PENDING_EXEC and added an new macro
6230 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6231 data or when error occurs while processing the pending command.
6233 Added new argument `destructor' into silc_server_command_pending
6234 and to the SilcServerCommandPending object. This destructor is
6235 now called after calling the pending callback or if error occurs
6236 immediately. If error occurs the actual pending callback won't
6237 be called at all - only the destructor. The destructor may be
6238 NULL if destructor is not needed.
6240 All this applies for client library code as well. Similar
6241 changes were made there as well for the pending commands.
6243 In the client, the application must now allocate the
6244 SilcClientCommandContext with the silc_client_command_alloc
6247 * Added reference counter to the SilcServerCommandContext. Added
6248 function silc_server_command_alloc and silc_server_command_dup
6251 Same type of functions added to the client library for the same
6254 * Removed the cmd_ident from IDListData away since it is now
6255 global for all connections. It is the command identifier used
6256 in command sending and with pending commands. The affected file
6259 * Added reference counter to the SilcSocketConnection objecet to
6260 indicate the usage count of the object. The object won't be
6261 freed untill the reference counter hits zero. Currently only
6262 server uses this, and client ignores it. The client must be
6263 set to use this too later. The affected files are
6264 lib/silccore/silcsockconn.[ch]. Added also the function
6265 silc_socket_dup to increase the reference counter.
6267 This was mainly added because it is possible that the socket
6268 is removed underneath of pending command or other async
6269 operation. Now it won't be free'd and proper DISCONNECTING
6270 flags, etc. can be set to avoid sending data to connection that
6271 is not valid anymore.
6273 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6274 the connection. After that it sets SILC_SET_DISCONNECTED.
6275 It is, however, possible that the socket data is not still freed.
6276 The silc_server_packet_process now checks that data is not
6277 read or written to connection that is DISCONNECTED. The socket
6278 get's freed when the reference counter hits zero.
6280 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6282 * Changed the client operation API: channel_message operation's
6283 `sender' is now the client entry of the sender, not the nickname
6284 and the `channel' is the channel entry, not the channel name.
6286 In the private_message operation the `sender' is now also the
6287 client entry of the sender not the nickname.
6289 Affected file is lib/silcclient/ops.h and all applications
6290 using the client operations.
6292 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6294 * Moved the calling of ops->connect() from connect_to_server_final
6295 into receive_new_id functin since that is the point when the
6296 client is actually allowed to send traffic to network. The
6297 affected file is lib/silcclient/client.c.
6299 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6301 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6302 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6303 (if needs broadcasting) instead of broadcasting the packets one
6304 by one which would make a burst in the network traffic.
6306 * Added `broadcast' argument to the functions in silcd/server.[ch]
6307 silc_server_create_new_channel[_with_id] to indicate whether
6308 to send New Channel packet to primary router.
6310 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Added new function into the silcd/server.[ch] files:
6313 silc_server_create_new_channel_with_id to create new channel with
6314 already existing Channel ID.
6316 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6317 lib/silccore/silcpacket.h. This packet is used t send list of
6318 Set Mode payloads inside one packet. Server uses this to set
6319 the modes for the channels and clients on those channels, that it
6320 announced to the router when it connected to it. The protocol
6321 specification has been updated accordingly.
6323 * The silc_server_new_channel did not handle the packet coming
6324 from normal server as it normally does not send that. However,
6325 when it announces its channels it does send it. Implemented
6326 the support for that.
6328 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6329 into the file lib/silccore/id.h.
6331 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * Fixed memory leaks in the functions silc_idlist_del_client,
6334 silc_idlist_del_channel and silc_idlist_del_server in the file
6335 silcd/idlist.c. All of those leaked like a sieve.
6337 * Fixed some small memory leaks in the client's function
6338 silc_client_notify_by_server.
6340 * Added functions into silcd/server.c: silc_server_announce_clients,
6341 silc_server_announce_channels and silc_server_announce_server.
6342 These functions are used by normal and router server to announce
6343 to its primary router about clients, channels and servers (when
6344 router) that we own. This is done after we've connected to the
6347 These functions effectively implements the following packet types:
6348 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6349 and SILC_PACKET_NEW_ID_LIST.
6351 * Added new functions into the silcd/packet_receive.[ch]:
6352 silc_server_new_id_list, silc_server_new_channel_list and
6353 silc_server_new_channel_user_list to handle the incoming
6354 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6356 * Added support of changing Channel ID in the function
6357 silc_server_replace_id. If the server that announces a channel
6358 to the router already exists in the router (with same name but
6359 with different Channel ID), router is responsible to send
6360 Replace ID packet to the server and force the server to change
6361 the Channel ID to the one router has.
6363 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6364 client that the Channel ID has been changed by the router. The
6365 normal server sends this to the client. Client must start using
6366 the new Channel ID as the channel's ID.
6368 Implemented handling of this new type into lib/silcclient/client.c
6369 into the function silc_client_notify_by_server.
6371 * Added new function silc_idlist_replace_channel_id into the files
6372 silcd/idlist.[ch] to replace the Channel ID.
6374 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Call silc_server_command_identify_check always when processing
6377 the IDENTIFY command in silcd/command.c
6379 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6381 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6382 send keepalive packets. The packet can be sent by clients,
6383 servers and routers.
6385 Added function silc_socket_set_heartbeat into the file
6386 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6387 If not set, the heartbeat is not performed. The actual
6388 heartbeat is implemented in the low level socket connection
6389 library. However, application is responsible of actually
6392 Added silc_server_send_heartbeat to send the actual heartbeat
6393 packet into silcd/packet_send.[ch]. Server now performs
6394 keepalive with all connections.
6396 * Added silc_task_get_first function into lib/silcutil/silctask.c
6397 to return the timeout task with shortest timeout. There was a bug
6398 in task unregistration that caused problems. TODO has been
6399 updated to include that task system must be rewritten.
6401 * The client library will now resolve the client information when
6402 receiving JOIN notify from server for client that we know but
6403 have incomplete information.
6405 * Rewrote parts of silc_server_remove_from_channels and
6406 silc_server_remove_from_one_channel as they did not remove the
6407 channel in some circumstances even though they should've.
6409 * Encryption problem encountered in server:
6411 The LEAVE command used to send the Channel Key packet to the
6412 router immediately after generating it. However, the code
6413 had earlier sent Remove Channel user packet but not immediately,
6414 ie. it was put to queue. The order of packets in the router
6415 was that Channel Key packet was first and Remove Channel User
6416 packet was second, even though they were encrypted in the
6417 reverse order. For this reason, MAC check failed. Now, this
6418 is fixed by not sending the Channel Key packet immediately but
6419 putting it to queue. However, this is more fundamental problem:
6420 packets that are in queue should actually not be encrypted
6421 because packets that are sent immediately gets encrypted
6422 actually with wrong IV (and thus MAC check fails). So, packets
6423 that are in queue should be encrypted when they are sent to
6424 the wire and not when they put to the queue.
6426 However, the problem is that the current system has not been
6427 designed to work that way. Instead, the packet is encrypted
6428 as soon as possible and left to the queue. The queue is then
6429 just purged into wire. There won't be any fixes for this
6430 any time soon. So, the current semantic for packet sending
6433 o If you send packet to remote host and do not force the send
6434 (the packet will be in queue) then all subsequent packets to the
6435 same remote host must also be put to the queue. Only after the
6436 queue has been purged is it safe again to force the packet
6439 o If you send all packets immediately then it safe to send
6440 any of subsequent packets through the queue, however, after
6441 the first packet is put to queue then any subsequent packets
6442 must also be put to the queue.
6444 Follow these rules and everything works fine.
6446 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6448 * Added new function silc_server_remove_clients_by_server to
6449 remove all client entries from ID list when the server connection
6450 is lost. In this case it is also important to invalidate all
6451 client entires as they hold the invalid server entry. This
6452 fixes fatal bug when server has lost connection and will reconnect
6455 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6457 * Made some sanity checks to silc_server_daemonise like to check
6458 whether the requested user and group actually exists.
6460 * Added sanity check to SKE's silc_ske_responder_finish to check
6461 that the public and private key actually is valid.
6463 * Invalidate the client's nickname when receiving Replace ID
6464 packet and the Client ID is being replaced. This means that the
6465 server will query the nickname if someone needs it (client)
6468 * Sort the ID Cache in client library when the ID Cache data
6469 has changed (needs sorting).
6471 * Do not allow for SILC client to create several connections to
6472 several servers. The client does not support windows right now
6473 and generating multiple connections causes weird behaviour.
6475 Irssi-silc client does support windows and can handle several
6476 connections without problems, see: www.irssi.org and SILC plugin.
6478 * Fixed some places where client was added to the IDList. The
6479 rule of thumb is following (in order to get everything right):
6480 If the client is directly connected local client then the
6481 `connection' argument must be set and `router' argument must be
6482 NULL to silc_idlist_add_client function. If the client is not
6483 directly connected client then the `router' argument must
6484 bet set and the `connection' argument must be NULL to the
6485 silc_idlist_add_client function.
6487 * The funtion silc_server_packet_send_local_channel actually did
6488 not check whether the client was locally connected or not. It
6489 does that now. Fixed a bug related to LEAVE command.
6491 * Fixed Remove Channel User payload parsing bug in server's
6492 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6494 * The server's silc_server_save_channel_key now checks also the
6495 global ID list for the channel as it might not be in the local
6496 list. Fixed a bug related to LEAVE command.
6498 * Is this the end of the [<unknown>] buglet that has been lurking
6499 around for a long time? A little for loop fix in server's
6500 silc_server_command_whois_parse that is used by both IDENTIFY
6501 and WHOIS command. At least, this was a clear bug and a cause
6502 of one type of [<unknown>] buglet.
6504 * WHOIS and IDENTIFY commands call the function
6505 silc_server_command_[whois/identify]_check function even if
6506 we are not router server.
6508 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6510 * Added --with-gmp configuration option. If set the GMP
6511 is always compiled in the SILC source tree. If not set then
6512 it is checked whether the system has the GMP3 installed. If
6513 it has then the GMP won't be compiled (the system's headers
6514 and library is used), if it doesn't have it then the GMP is
6515 compiled in the SILC source tree.
6517 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Changed RSA private exponent generation to what PKCS #1
6520 suggests. We try to find the smallest possible d by doing
6521 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6522 not security fix but optimization.
6524 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6526 * Added new config entry [Identity] to fork the server and run
6527 it as specific user and group. A patch from Bostik.
6529 * Imported Dotconf configuration library into lib/dotconf.
6530 This will be used to create the SILC configuration files later.
6531 It will appear in the distsribution after this commit.
6533 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6535 * A big code auditing weekend happening. Auditing code for
6536 obvious mistakes, bugs and errors. Also, removing any code
6539 Removed files for being obsolete:
6541 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6542 inline in the file lib/silcutil/silcbuffer.h)
6544 o lib/silcutil/silcbufutil.c (the header has inline versions)
6546 Changed code to fix possible error conditions:
6548 o The buffer formatting routines now check that the destination
6549 buffer really has enough space to add the data. This applies for
6550 both buffer formatting and unformatting
6551 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6552 unformatting was changed to accomodate following rules:
6553 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6554 sent to the function while XXX_*STRING will not allocate or copy
6555 the data into the buffer. Instead it sets the pointer from the
6556 buffer into the pointer sent as argument (XXX_*STRING used to
6557 require that the pointer must be allocated already). This change
6558 makes this whole thing a bit more consistent and more optimized
6559 (note that the data returned in the unformatting with XXX_*STRING
6560 must not be freed now). The routines return now -1 on error.
6562 o Tried to find all code that use buffer_format and buffer_unformat
6563 and added return value checking to prevent formatting and
6564 especially unformatting errors and possible subsequent fatal
6567 o Changed ske->x and ske->KEY to mallocated pointers in
6568 lib/silcske/silcske.h. Fixed possible data and memory leak.
6570 o Added return value checking to all *_parse* functions. Fixed
6571 many memory leaks as well.
6573 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6574 so that buffer overflows would not happen. All code now also
6575 checks the return value as it can fail.
6577 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6579 * Added reconnection support to server if the normal server looses
6580 its connection to the router (for example if router is rebooted).
6581 The server performs normal reconnection strategy implemented
6582 to the server. Affected file silcd/server.c.
6584 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6586 * Added new packet type SILC_PACKET_SET_MODE that is used to
6587 distribute the information about changed modes (for clients,
6588 channels and clients channel modes) to all routers in the
6589 network. Updated the protocol specification accordingly.
6591 Added functions into silcd/packet_send.c and
6592 silcd/packet_receive.c: silc_server_send_set_mode,
6593 silc_server_set_mode.
6595 Added new files silcmode.[ch] into lib/silccore that implements
6596 the encoding and decoding of Set Mode Payload. Added new type
6597 SilcSetModePayload. Moved the definitions of different modes
6598 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6600 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * Oops, a little mistake in server's connection authentication
6603 protocol. The protocol is not ended with FAILURE but with
6604 SUCCESS if the authentication is Ok. :) Affected file is
6607 * Implemented NICK_CHANGE notify handling in server in the file
6608 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6609 the local clients on the channel. After the changing nickname
6610 in router environment snhould work and the [<unknown>] nickname
6611 should appear no more.
6613 The silc_server_replace_id function that receives the Replace ID
6614 payload now sends the NICK_CHANGE notify type also in the file
6615 silcd/packet_receive.c
6617 * Changed WHOIS and IDENTIFY command to support the maximum amount
6618 of arguments defined in protocol specs (3328 arguments). This
6619 fixed a bug that caused problems when there were more than three
6622 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * Added extra parameter, command identifier, to the
6625 silc_client_send_command so that explicit command identifier
6628 Changed that ID list routines uses specific command identifier
6629 when sending WHOIS/IDENTIFY requests to the server so that they
6630 can be identified when the reply comes back.
6632 Affected files lib/silcclient/command.[ch],
6633 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6635 * Added `sender' argument to silc_server_packet_send_to_channel
6636 to indicaet the sender who originally sent the packet to us
6637 that we are now re-sending. Ignored if NULL. Affected file
6638 silcd/packet_send.[ch].
6640 * Added some server statistics support in silcd/server_internal.h
6641 SilcServerStatistics structure and around the server code. Also
6642 send some nice statistics information when client is connecting
6645 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Fixed channel ID decoding in server's JOIN command reply in
6648 silcd/command_reply.c
6650 * Fixed braodcasting of replace ID payload to not to send it if
6651 we are standalone server in silcd/packet_receive.c.
6653 * Fixed all channel message sending routines to not to send
6654 packets to clients that has router set, since they are routed
6655 separately in the same function earlier. Affects file
6656 silcd/packet_send.c and all channel packet sending functions.
6658 * In USERS reply, res_argv[i] are not allocated, the table
6659 is allocated. Thus changed that free the table, not its
6662 * In server's whois_check and identify_check if the client is
6663 locally connected do not send any WHOIS commands - they are not
6666 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Fixed some minor bugs in client when sending WHOIS command. The
6669 arguments was in wrong order.
6671 * Removed statis function add_to_channel from server in
6672 silcd/command.c that was previously used with the joining but
6675 * Tested USERS command in router environment successfully with two
6676 routers, two servers and two clients.
6678 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Reorganized the USERS command and command reply in client library
6681 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6682 When the command is given by user we register a pending command
6683 callback that will reprocess the command after the reply has been
6684 received from the server. When reprocessing the packet we then
6685 display the information. Thus, the USERS information is displayed
6686 now in the command callback instead of in the command reply
6687 callback. The processing of the command is same as previously
6688 when server has sent the command reply in the JOINing process.
6690 * Added to USERS command in silcd/command_reply.c to join the client,
6691 we didn't use to know about, to the channel after we've created
6692 a client entry for it. Also, for clienet we did know already still
6693 check whether it is on the channel or not and add it if not.
6695 * Removed silc_server_command_join_notify as the function and its
6698 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * Changed the client's pending command handling to the same as the
6701 server's pending command handling. It is also now possible to
6702 execute command reply functions from other command reply
6703 function as the function callbacks for commands and command
6704 replies are one and same. The pending commands are not static
6705 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6706 in client connection context. Thus, pending commands are server
6707 connection specific as it is convenient.
6709 Changed the function silc_client_command_pending and
6710 silc_client_command_pending_del and added new function
6711 silc_client_command_pending_check. Removed the
6712 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6715 * Added cmd_ident, current command identifier, to the client
6716 connection context in lib/silcclient/client.h to keep track on
6717 command identifiers used in command sending. Client's command reply
6718 function handling now supports the mandatory command identifiers.
6720 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6721 funtions in client to fully support pending command callbacks.
6723 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6724 as one of the arguments to the application in the command reply
6727 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6728 before first releasing SILC but came back. Now it is removed again
6729 and should come back nomore. The FORWARDED flag was used only
6730 by the JOINing procedure by forwarding the command packet to router.
6731 Now, the JOINing procedure has been changed to more generic (due
6732 to various router environment issues) and FORWARDED is not needed
6733 anymore for anything. The protocol specification is yet to be
6736 Now, removed silc_server_packet_forward from server and the flag
6737 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6739 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6741 * Renamed NAMES command to USERS command. The NAMES was named that
6742 due to historical reasons. Now it is renamed. Also, rewrote
6743 parts of the USERS command. The nickname list is not sent anymore
6744 by the server. Only Client ID and mode lists are sent in the USERS
6745 command. Changed this also to the protocol specification.
6747 The client now resolves the names and stuff after it receives
6748 the USERS list from the server when joining to the channel.
6750 * WHOIS and IDENTIFY commands has been changed to support multiple
6751 Client ID's per command. One can now search for multiple users
6752 in the network by sending only one WHOIS or IDENTIFY command.
6753 Changed the code and the protocol specifications.
6755 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6756 uses silc_server_command_whois_parse to parse the request. */
6758 * If normal server, do not parse the WHOIS and IDENTIFY requests
6759 before sending it to the router. Saves some time.
6761 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6763 * Fixed JOIN command on client library. Wrong number of arguments
6764 used to crash the client.
6766 * Added silc_server_channel_has_global function to check whether
6767 channel has global users or not.
6769 * Added silc_server_channel_has_local function to check whether channel
6770 has locally connected clients on the channel.
6772 * The silc_server_remove_from_one_channel now checks whether the
6773 channel has global users or not after given client was removed from
6774 the channel. It also checks whether the channel has local clients
6775 on the channel anymore. If it does not have then the channel entry
6776 is removed as it is not needed anymore.
6778 * The silc_server_notify now checks on JOIN notify whether the joining
6779 client is one of locally connected or global. If it is global then
6780 the channel has now global users on the channel and that is marked
6781 to the channel entry. Also, it now saves the global client to
6782 global list who is joining and JOINs it to the channel. This is
6783 for normal server, that is.
6785 Changed silc_server_send_notify_on_channel,
6786 silc_server_packet_relay_to_channel and
6787 silc_server_packet_send_to_channel check if we are normal server
6788 and client has router set (ie. global client) do not send the
6789 message to that client, as it is already routed to our router.
6791 * Implemented LEAVE notify type handling in silc_server_notify
6794 * Tested LEAVE command in router environment successfully. Tested
6795 with two routers, two servers and two clients.
6799 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6801 * Implemented SIGNOFF notify type handling in silc_server_notify
6804 * silc_server_remove_id now removes the client entry from all channels
6805 it has joined and thusly sends SIGNOFF notify type.
6807 * Rewrote the NAMES list generation in server by removing two excess
6808 loops. The lists are created now inside one loop.
6810 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * silc_server_remove_channel_user checks now also global list
6813 for channel and client.
6815 * silc_server_new_channel_user checks now both local and global
6816 list for channel and client. Fixed a bug in client id decoding.
6817 Used to decode wrong buffer.
6819 * silc_server_channel_message checks now both local and global
6820 list for channel entry.
6822 * Tested channel joining (hence JOIN) in router environment
6823 successfully. Tested with two routers, two servers and two
6826 * Tested channel message sending in router environment successfully.
6828 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6830 * Added silc_server_save_channel_key into server.[ch] to save the
6831 received channel key in Channel Key payload processing. It is
6832 also used in JOIN command reply handling.
6834 Equivalent function silc_client_save_channel_key added into
6835 client.[ch] into client library.
6837 * Changed JOIN command reply to send information whether the channel
6838 was created or not (is existing already) and the channel key
6839 payload. Changed protocol specs accordingly.
6841 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6842 the request was sent by ID and not by nickname. Crashed on
6845 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6848 now correctly save the received data.
6850 * silc_server_free_sock_user_data now notifies routers in the
6851 network about entities leaving the network.
6853 At the same time implemented functions silc_server_remove_id
6854 and silc_server_send_remove_id to receive and send REMOVE_ID
6855 packets. The packet is used to notify routers in the network
6856 about leaving entities. The ID removed will become invalid in
6859 * Added function silc_idlist_del_server into server. Removes and
6860 free's server entry from ID list.
6862 * silc_server_private_message function now checks, if we are router,
6863 that the destination ID really is valid ID, naturally.
6865 * In router when NEW_ID packet is received (for new client) the
6866 hash of the Client ID is saved in the ID Cache but the
6867 client->nickname is set to NULL, instead of putting the hash
6870 IDENTIFY command now also checks that client->nickname must be
6871 valid. If it is not if will request the data from the server who
6872 owns the client. Added new function
6873 silc_server_command_identify_check.
6875 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6876 to set the command to already allocated Command Payload.
6878 * Tested private message sending in router environment with two
6879 routers, two servers and two clients. Fixed minor bugs and now
6882 * Fixed segfault from client's NAMES command. Used to crash if
6885 * Forwarded packets must not be routed even if it is not destined
6886 to the receiver. Changed server code comply with this.
6888 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * Added `require_reverse_mapping' boolean value to ServerParams
6891 structure. If TRUE (not default) the server will require that
6892 the connecting host has fully qualified domain name.
6894 If the reverse mapping is not required and hostname could not be
6895 found the IP address is used as hostname.
6897 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6899 * Implemented version string checking to both client and server.
6900 The check is incomplete currently due to the abnormal version
6901 strings used in development version of SILC.
6903 * Changed all command functions in server to use the new
6906 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6908 * Changed char *data to unsigned char *data in ID Cache system to
6909 support binary data as ID Cache data. Changed code to support
6910 binary data in lib/silccore/idcache.c.
6912 * Renamed silc_server_packet_relay_command_reply to
6913 silc_server_command_reply as it is normal packet receiving
6914 function. Rewrote the function to accept command replys for
6915 servers and not only for clients.
6917 * Mark remote router always as registered server if we are connecting
6918 to it. Otherwise, commands sent by the router to us are ignored.
6920 * All ID List find routines now returns the ID Cache Entry pointer
6921 as well if requested.
6923 * WHOIS command works now in router environment, tested with two
6924 routers, two servers and two clients.
6926 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6927 in router environment (as it is almost equivalent to WHOIS) but
6928 hasn't been tested thoroughly. Added new functions:
6930 silc_server_command_identify_parse
6931 silc_server_command_identify_send_reply
6932 silc_server_command_identify_from_client
6933 silc_server_command_identify_from_server
6935 * Disabled route cache adding because adding two different ID's with
6936 same IP replaces the old cache entry thus giving wrong route.
6937 The entry->router->connection is always the fastest route anyway
6938 so route cache may not be needed. Of course, new routes maybe
6939 established after receiving the ID when the entry->router->connection
6940 might not be anymore the most optimal.
6942 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6944 * Add route cache for received ID for fast routing.
6946 * Added silc_server_packet_route to route received packet on router
6947 that is not destined to us.
6949 * Renamed silc_server_get_route to silc_server_route_get.
6951 * Added id_string and id_string_len fields into SilcServer to
6952 include encoded ServerID for fast comparing without excess
6953 encoding of the ID's.
6955 * Cleaned up WHOIS command on server side. Added following static
6958 silc_server_command_whois_parse
6959 silc_server_command_whois_check
6960 silc_server_command_whois_send_reply
6961 silc_server_command_whois_from_client
6962 silc_server_command_whois_from_server
6964 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6965 arguments in command replies. All command functions should be
6966 updated to use this macro.
6968 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6970 * Minor typo fixes on command reply handling on server.
6972 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6974 * Added silc_server_command_add_to_channel internal routine to add
6975 the client to the channel after router has created the channel and
6976 sent command reply to the server.
6978 * Added generic silc_server_send_command to send any command from
6981 * Use static buffer with ID rendering instead of duplicating data.
6983 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6985 * Fixed a channel user mode bug when joining to a channel server gave
6986 everybody channel founder rights, oops.
6988 * We mark ourselves as the router of the incoming server connection
6989 if we are router ourselves. This way we can check in some packet
6990 sending functions whether it is locally connected server. For
6991 incoming router connections we put NULL.
6993 * For router sending packets locally means now always sending the
6994 packet cell wide; to local clients and local servers. For normal
6995 server sending packet locally means sending it to only local
6998 * Fixed the JOIN command to really work in router environment. If the
6999 channel is created it is always created by the router. Router is
7000 also responsible of making the initial joining to the channel,
7001 sending JOIN notify to the sending server and distributing
7002 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7003 does not exist server doesn't do anything else but forward the
7004 command to the router which performs everything.
7006 * Added silc_server_send_channel_key function to send the Channel Key
7009 * Added silc_server_create_channel_key to create new channel key. The
7010 channel key is now re-generated everytime someone joins or leaves
7011 a channel, as protocol dictates. Note: channel->key_len is the
7014 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7016 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7017 packet_receive.[ch] to separate packet sending and receiving
7018 routines. The server.[ch] now includes everything else including
7019 actual packet processing (writing and reading data) and other
7022 Renamed silc_server_private_message_send_internal to
7023 silc_server_send_private_message. The routine is still though
7024 used only to relay private messages as server does not send
7025 private messages itself.
7027 Renamed silc_server_new_channel to silc_server_create_new_channel
7028 and added new function sicl_server_new_channel that handles the
7029 incoming New Channel packet. Added also new sending function
7030 silc_server_send_new_channel to send New Channel Payload.
7032 * Added new function silc_server_notify to process incoming notify
7033 packet to the server/router. Server may then relay the notify
7034 to clients if needed.
7036 * Added new function silc_server_new_channel_user to process incoming
7037 New Channel User packet. Router will redistribute the packet and
7038 send JOIN notify to its local clients and locally connected servers
7039 if needed. Normal server will send JOIN notify to its local client
7040 on same channel when received this packet. Added also corresponding
7041 sending function silc_server_send_new_channel_user to sent the
7044 * Added boolean route argument to send_notif_to_channel and
7045 packet_send_to_channel functions to attempt to route the packet
7046 if it is TRUE and send only locally if it is FALSE.
7048 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7050 * silc_server_replace_id now broadcasts the received replace ID
7051 packet if it is not broadcast packet already. The router must
7052 broadcast to inform other routers about changed ID.
7054 * Added backpointer to server's router into SilcServer context in
7055 silcd/server_internal.h.
7057 * Fixed silc_server_packet_broadcast to send correct broadcast
7060 * The channel key is now distributed to the local client as soon
7061 as it is received from the router (in router environment) so that
7062 no other packet may be sent for the channel until client has
7065 * silc_server_remove_channel_user now broadcasts the received
7066 Remove Channel User packet if it is not broadcast packet already.
7067 The router must broadcast to inform other routers about removed
7070 * Added users field into SilcPacketContext that is a reference count
7071 of the context. One can increase the reference count by calling
7072 silc_packet_context_dup which is now changed to just increase the
7073 reference count instead of duplicating the data. The reference
7074 count is decresed by calling silc_packet_context_free that will
7075 free the data after the reference count hits zero.
7077 For now on the packet context and everything allocated into it
7078 (including the raw packet from network) must be freed by calling
7079 the new silc_packet_context_free function. Added also new function
7080 silc_packet_context_alloc that must be used now to allocate the
7081 context. This also means that if a routine is asynchronous from
7082 silc_[client/server]_packet_parse_type the packet context must
7083 be duplicated by calling silc_packet_context_dup. Otherwise it
7084 gets free'd after silc_[client/server]_packet_parse_type returns.
7085 Also, one must remember that if packet is duplicated then its
7086 reference count must be decresed by calling the free function as
7087 many times as it was duplicated.
7089 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7090 from both client and server.
7092 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7094 * Made joining to a channel working in router environment.
7096 * Cleaned up JOIN command on server side and create function
7097 silc_server_command_join_channel internal routine to make the
7100 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7102 * Changed silc_command_pending list to SilcDList. Also, added
7103 `ident' field to SilcServerCommandPending structure to identify
7104 the reply and to call correct callback.
7106 Added silc_server_command_pending_check function to replace the
7107 corresnponding macro. The silc_command_pending list is not
7110 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7111 to set identifier to previously allocated Command Payload. It
7112 is used to set identifier for command when resending Command
7115 * Added silc_command_payload_encode_payload to encode Command
7116 Payload buffer from SilcCommandPayload structure.
7118 * Added silc_argument_payload_encode_payload to encode Argument
7119 payload buffer from SilcArgumentPayload structure.
7121 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7123 * Changed WHOIS command to support router connection on server side.
7124 The whois request is always sent to router unless the server is
7125 standalone server. After server has received the reply from the
7126 router will it send the reply to the client.
7128 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7129 broadcast received broadcast packet. The function is used only
7130 by router. The broadcast packet is always sent to the router's
7133 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7134 render given ID to printable string, for log files for example.
7136 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7138 * Made basic router to router connections working. At least they
7139 can now connect to each other but nothing really works the way
7140 they are supposed - yet.
7142 * Added new initiator token to RouterConnection configuration
7143 file in silcd/serverconfig.[ch]. It is used to tell whether we
7144 are the initiator to the remote router or whether we'll expect
7145 the other end to connect.
7147 * Moved registering of listener task to silc_server_init, hence
7148 the server starts listenning as soon as it is run, even if it
7149 does not have connections to other routers. Let's see how well
7152 * Changed default connection retry timeouts for more suitable in
7155 * Removed cipher and such arguments from silc_idlist_add_client
7156 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7157 Added new function silc_idlist_add_data to add the keys and stuff
7160 * Added SilcIDListData structure and added it to SilcClientEntry
7161 and SilcServerEntry as their first field in the structure. This
7162 way we can explicitly cast the ID entries to the SilcIDListData
7163 structure and get common data for the entries. In past, we had
7164 to first check what type of connection it is and then cast it to
7165 correct ID entry type. Now, we can directly cast the opaque
7166 pointer to the SilcIDListData (no matter what ID entry it actually
7167 is) and get the data needed.
7169 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7171 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7172 in some circumstances even if threre were timeout tasks, though not
7173 IO tasks, but tasks anyway. Now fixed.
7175 * Defined SilcServerConnection structure to hold connection specific
7176 stuff about directly connected servers and routers. The definition
7177 is currently in silcd/server_internal.h. I thought about having
7178 a bit more important role fro this struct but for now it is used
7179 only when connecting to other server (or router actually).
7181 * Added connecting retry support in server when connecting to
7182 router(s). The retry feature implement exponential backoff
7183 algorithm. Also, added SilcServerParams structure to hold default
7184 parameters for server. For now, it include these retry settings
7185 and are hard coded. After server is moded to be as Silc Server
7186 Library this structure will be more important.
7188 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7190 * Changed client librarys channel->clients table to SilcList and
7191 changed code accordingly.
7193 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7195 * Changed client's channel table to SilcList and changed code
7196 accordingly. Also changed SilcChannelClientEntry to include back-
7197 pointer to the channel so that client entry can use that structure
7198 as list as well and we have fast cross-reference to the channel.
7199 This change dramatically decreased the complexity of channel
7200 handling with client entry and vice versa (removed one extra
7201 loop when searching for channel entry from many functions).
7203 * Changed server->sim from table to SilcDList and changed code
7206 * NAMES command can now be used from user interface. It will show
7207 the user list on the channel, neatly.
7209 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7210 Code now saves realname of the user if it becomes available.
7212 * Renamed configure.in to configure.in.pre and made ./prepare
7213 script to automatically add correct version string to
7214 configure.in which it creates from configure.in.pre.
7216 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7218 * NAMES command reply now shows users mode with the nickname when
7221 * Moved silc_client_ch[u]mode[_char] functions from
7222 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7223 place sucks, they are utility functions and should be in some
7226 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7228 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7231 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7235 * Added TRQ (efficient deque and list library) into lib/trq. This is
7236 a very good list library that is currently used in the SILC. Defined
7237 SilcList API over the library because I didn't like the API very
7238 much. See lib/trq/silclist.h for the API and examples of how to
7239 use the API. Fixed various places in the code to use the new
7240 SilcList API. The SilcList is meant for lists that has a structure
7241 already defined as a list. It is not suitable to add just some
7242 context to the list (in TRQ, the context is the list actually).
7244 So, I defined SilcDList that can be used for the purpose where
7245 predefined list structure does not exit. This can be used as
7246 such list. Now some context just can be added to the SilcDList.
7247 Currently this list is not used in the SILC just yet, though there
7248 are a lot places where this can replace dynamically allocated
7249 tables and I will fix these places, later, to use SilcDList.
7250 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7251 and use TRQ internally).
7253 Also fixed some annoying warning messages that the original TRQ
7254 code generated. Also minor changes to TRQ's Makefile.in.
7256 * Added support for querying by Client ID to both WHOIS and
7257 IDENTIFY commands into server, as required by the protocol.
7259 * Removed method function pointers from SilcBuffer structure. They
7260 weren't used to anything and just increased the context size for
7261 no good reason. This change also made silc_buffer_alloc and
7262 silc_buffer_free functions inline functions.
7264 * Disabled command flooding detection support until it's fixed so
7265 that it accepts commands in but does not execute them more than once
7268 * Added silc_net_localhost(), to return local hostname, into
7269 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7270 that must be initialized before calling silc_client_init.
7272 * Added new function: silc_server_send_notify_on_channels to send
7273 notify messages to all channels client has joined. It is assured
7274 that the message is sent only once per client.
7276 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7277 lib/silcutil/silcutil.[ch] as silc_format function. The new
7278 function is generic and is used by server as well, not only by
7279 the logging routines.
7281 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7282 the provided version string was not acceptable. Added new function:
7283 silc_ske_check_version into lib/silcske/silcske.h. The function
7284 must be implemented by the application (client or server) and it
7285 does not reside in the SKE library. The function checks the version
7286 string remote end sent.
7288 * Added back pointers (to opaque context and to SilcSocketConnection)
7289 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7291 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7292 duplicate packet context structure.
7294 * Changed `notify' client operation to send same arguments as client
7295 receives from server except for ID's. ID's are mapped to correct
7296 ID entry and that is returned. Also, if channel entry is not sent
7297 by server but the notify is for channel the channel entry is sent
7298 to application (otherwise application doesn't know that it is for
7299 channel (library gets it from packet's Destination ID)).
7301 * Added silc_client_remove_from_channels into client library to
7302 remove a client from all channels it has joined to. Used when
7303 received SIGNOFF notify from server. Added also new function
7304 silc_client_replace_from_channels to replace old ID entry with
7305 new ID entry on all channels. Used when received NICK_CHANGE
7308 * Fixed ID Cache list handling in silc_idlist_get_client in
7309 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7310 to get (or query) client by ID.
7312 * Updated TODO list.
7314 * Added connection authentication status message defined by the
7315 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7316 support for these into the code in client and server side.
7318 * Added generic function silc_client_send_command to send any command
7319 with variable argument list. Application should use this function
7320 to send commands if the command functions provided by the library
7321 does not suite for the application's user interface needs.
7323 * Added new `failure' client operation. Application is notified about
7324 received failure packet if client is executing a protocol. In this
7325 case the protocol's execution has failed.
7327 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7328 is required by the protocol.
7330 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7331 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7334 * Added status flag to SilcSKE object to indicate realtime status
7335 of the SKE protocol.
7337 * Application receives now exactly same command reply arguments as
7338 the library receives from server. However, if ID is received the
7339 corresponding ID entry is returned to the application (eg. Client
7340 ID is mapped to correct SilcClientEntry entry and that is returned).
7341 Changed command_reply client operation due to this change.
7343 * Changed all ID's in commands and in command replys as ID Payloads.
7344 Change affected both client and server side codes.
7346 All ID's sent in SILC network (with execption of ID's in SILC
7347 Packet header) are sent in ID Payload to support variable length
7350 * Server now notifies nick changes and notifies all clients on
7351 the channels about the new nickname (about the new Client ID,
7354 * Implemented CMODE command to change channel modes. Supports all
7355 channel modes defined by the protocol specs except ban and invite
7356 lists. (Also, private channel key mode is supported but support for
7357 setting private channel key in client is missing, thus, this mode
7358 has no effect on client side (except that server requires that the
7359 client uses private channel key and normal channel traffic does not
7362 Also, invite mode works per se, but INVITE command does not work
7363 yet correctly, so you can set channel as invite only channel but
7364 inviting clients to the channel does not work (it is yet to be
7365 thought what's the best way to do it).
7367 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7368 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7369 Implemented CUMODE command to change user's mode on the channel.
7370 Supports all modes defined by the protocol specs.
7372 * Added NAMES command reply to return users modes on the channel.
7374 * Removed unnecessary and slow ciphers from lib/silccrypt.
7376 * Set SO_KEEPALIVE option to connection sockets by default.
7378 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7380 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7381 redefined the Notify Payload into protocol specs.
7383 * Added silc_id_payload_parse_id to get ID directly from raw
7386 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7388 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7389 accept searching by Client ID as well.
7391 * Added support for LEAVE and SIGNOFF notify types in client library.
7393 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7394 to parse ID Payload from raw data.
7396 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7398 * Added flags parameter into silc_ske_assemble_security_properties
7399 function in lib/silcske/silcske.[ch].
7401 * Changed notify client operation to fit better for notify messages
7402 sent by server. The notify payload received from server is now
7403 passed to the application (after parsing it to SilcNotifyPayload).
7404 It is application's responsibility to retrieve the arguments
7405 from the payload and show the message the way it wants. The message
7406 sent by server is implementation specific.
7408 * Changed public keys to comply with the protocol specification.
7409 Old public keys are not supported anymore and are not compatible.
7411 * Removed nickname from Channel Payload as the latest draft removed
7412 it. The client must resolve the nickname from the NAMES command
7413 reply received when it joined the channel.
7415 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7417 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7419 * Fixed some errors in protocol specification drafts.
7421 * Created lib/silccore/silcnotify.c to implement Notify Payload
7422 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7423 generic payloads described by protocol specifications. The file
7424 includes implementations for ID Payload and Argument Payload.
7426 * Changed Command Payload implementation to use the new Argument
7427 Payload. Changed command_xxxx_payload to command_payload_xxxx
7428 to comply with SILC coding conventions.
7430 * Added suppport for Argument Payload handling in Notify Payload
7431 implementation as protocol requires it. Added the new support
7432 into server and client lib as well.
7434 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7436 * Added support for multiple nicknames on same channel. [n] is
7437 added locally to the nickname if there are more than one same
7438 nicknames on the channel.
7440 * Server now sends all nicknames that matched WHOIS request.
7441 Client also shows the list received from server.
7443 * Added TOPIC command to client side. User can now set and show
7444 current topic on channel.
7446 * Added MOTD command to client and server. Also, server sends the
7447 motd when client connects to the server.
7449 * Changed version strings to comply ISO 8601.
7451 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7453 * Fixed protocol error handling in client library. It should now
7454 cope even if the SKE fails for some reason.
7456 * Made new protocol specification drafts for submitting to IETF.
7458 * Implemented TOPIC command to server in silcd/command.c.
7460 * Added two new notify types into lib/silccore/silcnotify.h:
7461 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7462 notify nickname change and topic setting/change on a channel.
7464 * API change of command_reply operation in client library. The
7465 application gets now the status type received from server as well.
7467 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7469 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7471 * Cras fixed and optimized the packet handling even further and
7472 it should work now. Minor change to the prototype of function
7473 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7475 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Added new function into lib/silcutil/silcschedule.[ch]:
7478 silc_schedule_with_fd to select() a specified fd. The function
7479 returns after timeout expires or data arrives or goes. The
7480 function is used by packet routines to wait that all data is
7481 received from network.
7483 * Fixed data reading from network in lib/silccore/silcpacket.c.
7484 The code now assures that all data is read from the fd and then
7485 continues packet processing. This was a bug fix since the code
7486 used to drop some data in some circumstances.
7488 * Added new function into lib/silcclient/client.[ch]:
7489 silc_client_start_key_exchange to start key exchange after
7490 connection has been established to server. The code internally
7491 now uses this funtion but its main purpose was to provide it
7492 for applications that perform their own connecting. After
7493 application has created a connection it merely calls this
7494 function to start the key exchange between client and server.
7495 The library takes care of everything else after that.
7497 Updated also lib/silcclient/README to explain the usage of
7500 * Do not send to application information that connection has
7501 been established. Application gets notified it by connect
7504 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7506 * Applied cras's patch to add silc_schedule_one function. The
7507 function runs scheduler once and returns.
7509 * Fixed the scheduler after cras messed it up. The timeout
7510 handling works now as it's supposed to work.
7512 * Added into lib/silccore/ silcnotify.h to include notify
7513 message types support. Changed silc_server_send_notify*
7514 functions, in server.[ch], to support those new notify types.
7515 Added the support for the notify types into client library,
7516 as well. Added new notify client operation into ops.h in
7519 * Changed silc_server_packet_send_to_channel to send normal
7520 packets instead of just channel message packets. The function
7521 is now used to send the notify packets to channels. It is not
7522 used to send channel message packets anymore, as server never
7525 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7526 va_arg()s as it seems to require it nowadays. I guess, if SILC
7527 is compiled with older va_arg() the new code should work anyway.
7529 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7531 * Splitted core library. Core library (lib/silccore) includes
7532 now only SILC protocol specific core (and common) components.
7533 Created new utility library (lib/silcutil) that includes more
7534 generic purpose stuff. The stuff for util library was taken
7535 from the old core library. This was minor and easy split.
7537 * Created SILC Client Library (lib/silcclient) that includes
7538 implementation of the SILC client without user interface. This
7539 was major move from silc/ directory. The code has been changed
7540 so that it is transparent towards the user interface. The
7541 silc/ directory includes now the same user interface as before
7542 and it uses the new client library. Read lib/silcclient/README.
7543 Basicly, the client library performs everything else related
7544 to SILC except user interface handling. Also, configuration
7545 files are considered to be part of user interface and library
7546 does not handle them.
7548 This change also changed a lot of structures, function naming etc.
7549 Most important change was that SilcClientWindow object was
7550 renamed to SilcClientConnection in the client library. Created
7551 also new file lib/silcclient/ops.h. Also added new files
7552 silc/local_command.[ch] and silc/client_ops.[ch].
7554 All these changes were made to make it easier for user interface
7555 designers to create what ever user interface for the SILC client
7558 It is also expected that the server will be moved to lib
7559 directory as well and SILC Server Library will be created;
7560 sometimes in the future.
7562 * Removed Local commands from lib/silccore/silccommand.h as
7563 they are application specific and new client library does not
7564 handle any of those anymore.
7566 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7567 old client implementation in silc/.
7569 * Added support for callback functions in SILC_LOG_* macros.
7570 Application can now set its own callbacks that will be called
7571 instead of using the default functions that will always print
7572 the debug messages to stderr (or stdout). Also, debugging can
7573 now be disabled by setting silc_debug to FALSE and re-enabled by
7574 setting it to TRUE. Note, that logging will still work even
7575 if debugging is disabled.
7577 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7578 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7579 silc_log_reset_debug_callbacks.
7581 * To enable debugging in silc client one must give now -d
7582 option on command line.
7584 * Changed silc_schedule_init to automatically allocate task queues
7585 if they are not allocated before calling it.
7587 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7589 * Added GMP 3.1 into math library.
7591 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7593 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7594 a channel in SILC network. The packet is used by servers and
7595 routers to notify other routers that user has left a channel.
7596 This little feature was missing until now. Added the feature
7597 to protocol specification as well.
7599 Added functions: silc_server_send_remove_channel_user and
7600 silc_server_remove_channel_user into server.[ch].
7602 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7603 lib/silccore/silcpacket.h. However, they are not implemented
7606 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7608 * Fixed joining to a channel and sending channel messages
7609 between server and router. The channel message sending should
7610 now work inside a cell.
7612 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7614 * Fixed the private message sending between server and router.
7615 The private message sending should now work inside a cell.
7617 * Added silc_server_replace_id into server.[ch] to replace
7618 existing ID in the SILC network.
7620 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7621 and silc_idlist_replace_server_id into idlist.[ch] in server.
7623 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7625 * Fixed the server to server connections. Server can again now
7626 connect to router. Router to router connections probably does
7629 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7631 * Added dynamic protocol registering support. Now protocols can
7632 registered and unregistered on the fly. Patch by cras.
7634 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7636 * Added lib/contrib directory to hold routines that some platforms
7637 don't have but are needed by SILC.
7639 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7640 into lin/contrib to provide getopt() and getopt_long() for
7641 those who don't have it.
7643 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7645 * Added AWAY command to client. When away message is set and
7646 client receives a private message packet the client automatically
7647 replies to the sender with the away message.
7649 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7650 bug seemed to be the cause of recent problems when compiling
7653 * Added version detection support to SKE protocol specification
7654 and added the new changes to the SKE implementation as well.
7655 There were other minor changes in the SKE protocol as well.
7657 Many changes in lib/silcske/silcske.[ch] and in
7658 lib/silcske/payload.[ch].
7660 * Added ^U functionality, clear input line. Patch from cras.
7662 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7664 * Mainly small bugfixes on core library. Fixed some debugging
7665 logging and buffer overflow in silclog.c.
7667 * Updated config.sub and config.guess on the distribution tree.
7669 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7671 * Added command lagging support in server. Client may execute
7672 commands now only once in two seconds.
7674 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7676 * Optimized packet reception. MAC computation and checking is now
7677 also more optimized. A lot previously duplicated code is now
7678 used as generic by both client and server.
7680 * Fixed key pair generation in clientutil.c
7682 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7684 * Added into lib/silccore/silcbufutil.[ch] new function;
7685 silc_buffer_realloc.
7687 * Moved generic packet sending/encryption functions to
7688 lib/silccore/silcpacket.[ch] from client and server. Some
7689 rewriting of the functions.
7691 * Moved all generic packet reception/decryption functions to
7692 lib/silccore/silcpacket.[ch] from client and server. The
7693 packet processing is now much cleaner in both client and server.
7694 These were major changes in both client and server.
7696 * Created many common functions in server to do packet sending.
7697 Previously code were duplicated a lot, this has been removed
7700 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7702 * Rewrote major parts of the ID cache system. Don't know
7703 whether it is better now or not but at least the API is more
7706 * Major rewrite on ID cache stuff on client because of the ID
7707 cache API changes. Added idlist.c to client.
7709 * Also major rewrite on ID cache stuff on server as well.
7710 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7711 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7712 in hand, instead they are all put into the ID cache system now.
7713 All server_idlist_* routines uses ID cache now instead of
7714 traversing its own lists (those lists does not exist anymore).
7715 SilcIDList though still exists. Also, SilcXXXEntry's are
7718 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7720 * Finally made the SKE implementation compliant to the protocol
7721 specification. All mp integers are now binary encoded as
7722 opposed being HEX encoded.
7724 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7727 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7728 functions: silc_[encode/decode]_pem. Also added function
7729 silc_encode_pem_file to PEM encode with newlines ('\n') for
7732 * SILC public keys are now encoded either PEM or binary. Same
7733 option is for private keys as well. By default private keys
7734 are binary encoded and public keys PEM encoded. Silly HEX
7735 encoding were removed.
7737 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7738 function to create fingerprints.
7740 * Fixed a bug in SHA1; does not change the original data anymore.
7742 * Partly implemented INFO command on client and server side.
7743 Fixed CLEAR command. Changes to SERVER command; show current
7744 server(s) when giving command without arguments. Added
7745 VERSION command to client.
7747 * Added check to server that unregistered connections cannot
7748 execute commands (unless it is specificly allowed).
7750 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7752 * Fixed screen refresh.
7754 * Fixed channel joining bug from client. On some circumstances
7755 client tried to join to a channel it had already joined.
7757 * Added public key verification process into client's protocol.c.
7758 The client now verifies the public key from user and saves
7759 it into ~./silc/serverkeys/ directory.
7761 Added into: clientutil.[ch]: silc_client_verify_server_key.
7763 * Changed SKE protocol's silc_ske_initiator_finish function
7764 to accept callback function that verifies the received public
7765 key. Removed old silc_ske_verify_public_key function.
7767 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7769 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7770 silc_pkcs_private_key[_data]_set.
7772 * Made the password and public authentication more cleaner in
7773 server's protocol.c.
7775 * Removed historic and obsolete protocol `channel_auth' from
7776 both client and server.
7778 * Removed wrong way of sending command status messages from
7779 server to client in server's command.c. The old way violated
7780 protocol specification.
7782 Changes to silccore/silccommand.[ch]: removed
7783 silc_command_encode_status_payload -> not needed anymore,
7784 changed silc_command_encode_payload_va to accept extra
7785 argument on variable argument list. The argument type must
7786 now be provided to the function. Also, added new function:
7787 silc_command_encode_reply_payload_va which is same as
7788 normal command_encode_payload_va except command status type
7789 is provided as extra argument.
7791 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7793 * Added ~./silc directory handling. The directory includes the
7794 public and private keys for the client.
7796 Added silc_client_check_silc_dir, silc_client_create_identifier
7797 and silc_client_load_keys.
7799 * Implemented SILC protocol compliant public key. Added public
7800 and private key saving to and loading from files.
7802 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7803 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7804 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7805 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7806 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7808 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7809 silc_pkcs_load_[public/private]_key.
7811 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7813 * Added silc_server_get_route (route.[ch]) to get connection
7814 data for the fastest route for given ID.
7816 * Implemented INVITE command on client and server. The command
7817 were re-defined in the SILC Protocol Specification and the
7818 implementation now complies with the specification.
7820 * Implemented PING command on client and server.
7822 * Implemented NAMES command on client and server. The server side
7823 supports currently only normal server not router server yet.
7824 Some changes to NAMES definition in SILC protocol specification.
7826 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7828 * Implemented LEAVE command on client and server.
7830 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7831 again. This change was made to the protocol as well. Server
7832 should not violate the protocol specification anymore.
7834 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7836 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7837 was tested. SOCKS4 was not but should work anyway.
