1 Sun Apr 14 20:41:28 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
3 * Fixed a bug in library where sending a bogus authentication
4 payload would lead to a crash. Affected file is
5 lib/silccore/silcauth.c.
7 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
9 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
10 must be handled by the application and should tell the application
11 that an error message was already printed, and it should print the
12 config coords (line, filename, ...). Affected files are
13 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
15 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
16 server config parsing code more readable.
18 Fixed a bug in the fetch_logging() config callback.
20 Affected files is silcd/serverconfig.c.
22 * Drop root privileges when started in foreground. Don't drop them
23 if debugging also. Affected file is silcd/silcd.c.
25 Wed Apr 3 12:36:05 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
27 * Added better error logging in rekey protocol. Affected file
30 * Do not check public key types in SKE during rekey. Affected
31 file lib/silcske/payload.c.
33 * Fixed the rekey protocol with PFS, which was totally broken.
34 Affected file silcd/protocol.c.
36 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
38 * Merged version 1.1.4 of zlib. Even if it not currently in use,
39 it's good not to have security holes here.
41 * Fixed a negative refcount situtuation for the config context.
42 Affected file is silcd/serverconfig.c.
44 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
46 * ROBOdoc documented lib/silcutil/silcutil.h.
48 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
50 * Changed the silc_get_username and silc_get_real_name to
51 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
53 * Fixed the Irssi SILC Client to use the silc_get_username and
54 silc_get_real_name insted of glib routines since the glib
55 routines only corrupt stack. Fixes the Irssi SILC to work in
56 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
58 * Fixed the Irssi to not use g_get_home_dir since it crashes
59 or returns garbage on cygwin and corrupts stack. Added function
60 get_home_dir to Irssi routines. Affected files are
61 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
63 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
65 * And yet again reverted back the config thing since Johnny
66 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
69 * Fixed memory leaks from config object. Affected files are
70 silcd/serverconfig.[ch].
72 * Added support for adding new connections to the server in rehash.
73 After rehash they take effect.
75 Added support for changing the maximum allowed connections in
76 rehash. The number can grow but going smaller is not supported.
78 Added function silc_server_num_sockets_by_remote to the
79 silcd/server_util.[ch].
81 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
83 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
85 * Added preliminary checking during config parsing for a valid
86 public/private key and removed further checks in the code.
87 Affected files are silcd/serverconfig.[ch], server.c.
89 * Moved functions silc_server_drop() and silc_server_daemonise()
90 from server.c to silcd.c since they are stricly related to
91 the application activity.
93 * Reverted a small part of the automatic ref/unref since
94 it caused a double unref in some situations. Affected
95 files are silcd/silcd.[ch], server.c, serverconfig.c.
97 * Added some .cvsignore files in the lib directory.
99 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
101 * Fixed silc_net_gethostbyaddr to correctly resolve by
102 address. Affected file lib/silcutil/silcnet.c.
104 * Fixed the notify relaying to client. The HMAC to be used
105 with relayed packets ws wrong and caused decryption failure
106 at the client end. Affected file is silcd/packet_receive.c.
108 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
110 * Created new branch silc_protocol_1_0_branch.
112 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
114 * Changed the silc_server_config_* routines to be SilcServer
115 independent. They are now officially application specific code
116 and not part of generic server implementation. Affected files
117 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
119 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
121 * Added automatic referencing of config context in the
122 silc_server_config_alloc, and automatic unreferencing in the
123 silc_server_config_destroy. Affected files are
124 silcd/serverconfig.[ch], silcd/silcd.c.
126 * Fixed the silc_log_quick handling in the logging routines.
127 It didn't log quickly when it was TRUE. Affected file is
128 lib/silcutil/silclog.c. Also the flush delay was set even
129 if it was 0 in config file. Affected file is
130 silcd/serverconfig.c.
132 * Added support for changing key pair of the server in rehash.
133 Affected file silcd/server.c.
135 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
137 * Fixed the TOPIC_SET notify to not cras. It changed the topic
138 too early, before getting the channel entry. Affected file
139 is silcd/packet_receive.c.
141 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
143 * Added functions silc_server_config_[ref/unref], these are used
144 to prevent that the config object is destroyed.
146 No longer directly affect global variables silc_log_quick and
147 silc_log_delay, they are first cached inside the config object
148 and then applied with silc_server_config_setlogfiles().
150 silc_server_config_set_defaults() is now internal to
151 serverconfig.c, there are no reasons to show this internal stuff
154 Affected files are silcd/serverconfig.[ch].
156 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
157 fprintf's to stderr, since some code may be executed again after
158 the server went into the background. Affected files are
161 * Added rehash support. Added function silc_server_rehash() that
162 will perform all the basic tasks of the rehashing procedure.
164 * Added command line option `-x, --hexdump'. This will enable the
165 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
166 The option `--hexdump' implies `--debug'.
168 * Fixed a bad bug in the logging APIs (silcutil library) where
169 the application would crash after calling silc_log_reset_all().
171 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
173 * Fixed the KICKED notify handling in client library to
174 correctly remove the channel and all entries from the
175 channel when I was kicked. This bug crashed the client.
177 Fixed yet another but in KICKED notify handling to remove
178 the kicked client correctly from the channel.
180 Affected file is lib/silcclient/client_notify.c.
182 * Fixed a minor bug in looking up correct client entry
183 in KICKED notify in server. Affected file is
184 silcd/packet_receive.c.
186 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
187 sources correctly to distribution. Fixes --with-gmp option.
189 * Removed the manual rehashing from ID Cache, and changed it
190 to use the SILC Hash Table's auto rehash feature. Affected
191 file is lib/silccore/silcidcache.c.
193 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
195 * Fixed a bug in the silc_client_nickname_format function that
196 handles the multiple same nickname formatting. Two clients
197 with same nickname caused problems after the first one left
198 and rejoined. It didn't format the nickname correctly.
199 Affected file is lib/silcclient/idlist.c.
201 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
203 * Don't change the topic if olod topic is same as new one.
204 Affected file is silcd/packet_receive.c.
206 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
208 * Added cross-reference support to the SILC Documentation
209 generator. All types across all HTML files are now cross-
210 referenced. Affected files util/robodoc/generator.c and
211 scripts/silcdoc/silcdoc.
213 * Added file lib/silcutil/silctypes.h to include all the
214 arithmetic type definitions and some macros. Removed
215 includes/bitmove.h and moved macros to silctypes.h.
217 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
219 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
221 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
223 * Added `type' argument to silc_id_payload_parse_id function which
224 now returns the type of the ID to the sent pointer. Affected
225 file is lib/silccore/silcid.[ch].
227 * Added check for CMODE_CHANGE notify type that mode change is
228 allowed by the sender. Affected file silcd/packet_receive.c.
230 * Added check for CUMODE_CHANGE notify type that mode change is
231 allowed by the sender. Affected file silcd/packet_receive.c.
232 Added the ID type as CUMODE_CHANGE notify type as argument
233 to the `notify' client operation. Affected files are
234 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
236 * Added function silc_client_add_server to the client library.
237 Added support for resolving also channel and server info when
238 received unknown entity in notify packet. Affected files are
239 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
241 * Added function silc_command_get_status to return the command
242 status from the command reply's argument payload. Affected files
243 are lib/silccore/silccommand.[ch].
245 * Added check for KICKED notify type that the kicking is
246 allowed by the client. Affected file silcd/packet_receive.c.
248 * Created function silc_get_input which can be used to get input
249 (echo on or off) from user on command line. Affected files are
250 lib/silcutil/silcutil.[ch].
252 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
254 * Optimized silc_server_packet_relay_to_channel function.
255 Added new function silc_channel_message_payload_encrypt which
256 can be called directly if channel message payload needs to
257 be encrypted and is already encoded (no need to call _encode
258 function). Packet relaying is now done by router without any
259 extra memory allocations. Affected files are
260 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
263 * Fixed the INVITE notify handling. It took wrong arguments
264 as invite list and invite delete. Affected file is
265 silcd/packet_receive.c.
267 * Added check for TOPIC_SET notify type that the topic change is
268 allowed by the client. Affected file silcd/packet_receive.c.
270 * Added check for INVITE notify type that inviting is allowed by
271 the client. Affected file silcd/packet_receive.c.
273 * Changed the silc_server_client_on_channel to return the
274 SilcChannelClientEntry as well. Moved the function
275 silc_server_check_cmode_rights to server_util.[ch].
276 Affected files are silcd/server_util.[ch], silcd/command.c.
278 * Added function silc_server_check_umode_rights to check whether
279 changing client's user mode is allowed. Added check for
280 UMODE_CHANGE notify type that the umode change is allowed
281 by the client. Affected files are silcd/server_util.[ch],
282 silcd/packet_receive.c and silcd/command.c.
284 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
286 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
287 ID length. It ignored that ID can be IPv6 based as well.
288 Affected file lib/silccore/silcpacket.h.
290 * Fixed the silc_id_id2str and silc_id_str2id to take the
291 IPv6 address offset's into consideration. Affecte file is
292 lib/silccore/silcid.c.
294 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
296 * Fixed the internal Unix scheduler functions to check for
297 NULL context they may receive. The affected file is
298 lib/silcutil/unix/silcunixschedule.c.
300 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
302 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
303 can specify different directory with --home command line
304 parameter. Affected files irssi/src/silc/core/client_ops.c,
307 * SILC-specific commands aren't now executed if the active server
308 isn't of SILC-type, so there won't be problems with having
309 IRC and SILC protocol support in same client. Affected files
310 irssi/src/silc/core/silc-channels.c, silc-servers.c,
313 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
315 * Improved the signal support in SILC Schedule. Added new
316 function silc_schedule_signal_call which is used by application
317 to mark a signal to be called. It is now safe to perform
318 any kind of tasks in signal callbacks since it is guaranteed
319 that the application specified signal callback is called
320 after the signal is over. Affected files are
321 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
323 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
325 * Added `name' field to SilcChannelPrivateKey to represent
326 application given name for the key. Moved also the context from
327 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
328 Added the `name' argument also to the function
329 silc_client_add_channel_private_key.
331 Added function silc_client_current_channel_private_key to set the
332 current channel private key in use.
334 Added "change" command to KEY command which can be used to change
335 the current channel private key. Bound the command also to
338 Also affected files lib/silcclient/client_channel.c,
339 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
341 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
343 * Added silc_rng_get_byte_fast function in to the
344 lib/silccrypt/silcrng.[ch].
346 * Changed the interface of silc_packet_assemble and the
347 silc_packet_send_prepare. If silc_packet_assmble is now
348 called the application does not call silc_packet_send_prepare
349 because the library will call it automatically. These
350 interfaces now also return a reference to the outgoing buffer
351 which includes the assembled packet, which the application can
352 use to encrypt the packet.
354 Affected files are lib/silccore/silcpacket.[ch],
355 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
356 silcd/packet_send.c, server_backup.c and packet_receive.c.
358 * Fixed a packet sending bug on very high load, where outgoing
359 packet queue wasn't handled correctly and packets got corrupted.
360 Affected files are lib/silcutil/*/silc*sockconn.c,
361 lib/silcclient/client.c and silcd/server.c.
363 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
365 * Added macro SILC_PACKET_DATALEN which can be used during
366 packet assembling to check whether the data to be added to
367 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
368 len is truncated until it fits it.
370 Added checks for maximum length of channel message payload and
371 private message payload also.
373 Added checks for maximum packet length in server and in
376 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
377 lib/silcclient/client.c, lib/silccore/silcchannel.c and
378 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
379 lib/silcclient/client_prvmsg.c.
381 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
383 * Added silc_server_packet_queue_purge call to the
384 silc_server_disconnect_remote to assure that all data in the
385 queue before disconnecting is sent to the network. Affected
388 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
390 * Added the deleting of server's own ID cache entry to the
391 silc_server_free function. Free also everything else that
392 has been allocated in silc_server_init. The affected file
395 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
397 * Added functions silc_parse_version_string, silc_version_to_num,
398 and silc_ske_parse_version to parse SILC protocol style version
399 strings. Affected files lib/silcutil/silcutil.[ch] and
400 lib/silcske/silcske.[ch].
402 * Added new configuration params: version_protocol, version_software
403 and version_software_vendor to specify what version the remote
404 host must at least be to be able to connect to server. The vendor
405 string can be regex matched too. Added new function
406 silc_server_connection_allowed to check maximum number of allowed
407 connections, and allowed versions for incoming connections.
408 Affected files are silcd/server.c, server_util.[ch] and
411 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
413 * Added preliminary support for signals in scheduler. The
414 signals we care about are now blocked always when the scheduler
415 is locked. This way we can synchronise the use of signal with
416 scheduler. It is guaranteed that when signal occurs the scheduler
417 is not locked, and thus new tasks can be safely added to the
420 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
421 to silc_schedule_internal_init and silc_schedule_internal_uninit.
422 Added new platform specific routines
423 silc_schedule_internal_signals_[un]block and
424 silc_schedule_internal_signal_[un]register.
426 Added new functions to SILC Schedule API:
427 silc_schedule_signal_[un]register. Each signal that application
428 is going to use should be registered to the scheduler.
430 Affected files are lib/silcutil/silcschedule.[ch],
431 lib/silcutil/*/silc*schedule.c.
433 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
435 * Check for unauthenticated client and server in the
436 silc_server_new_client and silc_server_new_server functions.
437 Affected file silcd/packet_receive.c.
439 * Added function silc_string_is_ascii to check whether given
440 string is 7-bit ASCII string. Affected files are
441 lib/silcutil/silcutil.[ch].
443 * Added function silc_id_is_valid_server_id into the
444 silcd/serverid.c and added checking for valid Server ID's in
445 silc_server_new_server. The Server ID must always be based
446 on the server's public IP address.
448 * Added logging of DISCONNECT packet message in the server.
449 Affected file silcd/server.c.
451 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
453 * Changed all library interfaces that use Global RNG to also
454 accept SilcRng as argument. Affected files are
455 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
456 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
457 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
458 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
461 * Added function silc_pkcs_generate_key to the
462 lib/silccrypt/silcpkcs.[ch] for applications so that they
463 don't need to do pkcs->pkcs->init calls anymore.
465 * Remove SilcSocketConnection from the SFTP API since it really
466 wasn't needed there. The application has the information
467 saved in its contexts anyway and the SFTP layer doesn't need
468 know about it. Affected files lib/silcsft/silcsftp.h and
469 lib/silcsftp/sftp_[server/client].c.
471 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
472 The SilcSimContext is not SilcSim.
474 * Fixed possible buffer overflows in silc_id_render in the
475 lib/silcutil/silcutil.c.
477 * On EPOC the global crypto module lists are not used at all
478 in the crypto library. Added support for using the constant
479 algorithm list on EPOC. Affected files are
480 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
483 * Fixed the handling of third parameter of KICKED notify, since
484 it was mistakenly updated to SILC Protocol 1.0 even though it
485 is to be included in 1.1. Since it is not in 1.0 it is not
486 mandatory, and this fix now handles it only if it is provided,
487 and it is not error if it is not provided. Affected file
488 lib/silcclient/client_notify.c.
490 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
492 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
493 client. Affected file irssi/src/silc/core/client_ops.c.
495 * Merged with Irssi 0.8.4 from irssi.org CVS.
497 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
499 * Check for valid socket connection in client entries before
500 sending any messages. Fixes a crash, but doesn't fix some
501 other underlaying bug that is lurking there. Affected
502 file silcd/packet_send.c.
504 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
506 * $usermode, $cumode and $cumode_space expandos shouldn't do
507 anything with non-SILC server records. Affected file
508 irssi/src/silc/core/silc-expandos.c
510 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
512 * Fixed the silc_net_check_[host/local]_by_sock to support
513 IPv6 bound sockets as well. Now they can return IPv6 addresses
514 as well. Affected file lib/silcutil/silcnet.c.
516 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
517 Affected lib/silcutil/unix/silcunixnet.c.
519 * Fixed ID rendering (at least on some platforms, not NetBSD)
520 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
522 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
524 * Added silc_hash_public_key and silc_hash_public_key_compare
525 functions to be used with SilcHashTable. They can be used to
526 hash public keys and compare public keys in hash table. Affected
527 file lib/silcutil/silcutil.[ch].
529 * Added support for specifying multiple public keys for Client
530 connection section in server configuration file. This makes it
531 possible to accept multiple public keys from same host, or to
532 make a section that accepts any incoming host, and have the
533 accepted public keys listed in the section.
535 Added functions silc_sever_[find/get]_public_key, added the

709 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
711 * ROBOdoc documented the lib/silcske/silcske.h, and improved
712 the SKE interface a bit.
714 * Fixed padding problem in PKCS#1. The padding was not actually
715 random since the random number generator was used incorrectly.
716 This security bug affects only when encrypting with PKCS#1, and
717 it is not currently used at all in SILC. SILC only use signing
718 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
720 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

799 algorithm parts and created new file silcalgs.conf, that
800 is now included from the example_silcd.conf.in.
802 * Optimized the silc_server_connect_to_router_second to take
803 the connection configuration object from the SilcServerConnection
804 object instead of finding it during the connecting phase.
805 Added the configuration object to SilcServerConnection struct.
806 Affected files silcd/server_internal.h, server.c.

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

890 * Fixed the file transfer's key agreement payload to include
891 zero port also if the hostname is NULL because it could not
894 Call file transfer monitor callback now also if error occurs
895 during key agreement protocol.
897 Changed the silc_client_file_send interface to return the
898 SilcClientFileError instead of session id. The session ID
899 is returned into pointer provided as argument.

916 file lib/silcutil/silclog.c.
918 * Fixed the channel message payload decryption in the function
919 silc_channel_message_payload_decrypt to not modify the original
920 buffer before it is verified that the message decrypted
921 correctly. Otherwise, next time it is called with correct
922 channel key it won't encrypt since the payload is corrupted.
923 Affected file lib/silccore/silcchannel.c.
925 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

939 become invalid in the callback but it was referenced after
940 the callback returned.
942 Do not allow auto rehashing of hash table during the
943 silc_hash_table_foreach operation, for same reasons as it is
944 not allowed for SilcHashTableList. Affected files are
945 lib/silcutil/silchashtable.[ch].
947 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

968 users list to SilcHashTable. The affected files are
969 lib/silcclient/idlist.[ch].
971 * Fixed a bug in hash table tarversing. While the hash table
972 is traversed with SilcHashTableList the table must not be
973 rehashed. It is now guaranteed that auto rehashable tables
974 are not rehashed while tarversing the list. Also defined that
975 silc_hash_table_rehash must not be called while tarversing
976 the table. Added function silc_hash_table_list_reset that must
977 be called after the tarversing is over. The affected files are
978 lib/silcutil/silchashtable.[ch].
980 * Changed all hash table traversing to call the new
981 silc_hash_table_list_reset in server and in client library.
983 * Added function silc_client_on_channel to return the
984 SilcChannelUser entry if the specified client entry is joined

995 lists correctly. Affected file silcd/command.c.
997 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
999 * When sending JOIN command to router for processing the
1000 sender's old command identifier was not saved back to the
1001 sender's command context, fixed now. The affected file is
1004 * Create the key in JOIN command of the router did not return
1005 the channel key, added check for this. Affected file is
1008 * Fixed a channel ID update bug in JOIN command reply. Do
1009 not directly upgrade the ID but call the function
1010 silc_idlist_replace_channel_id if the ID was changed.
1011 Affected file silcd/command_reply.c.
1013 * Fixed memory leaks from command calling if it would fail.
1014 Affected file silcd/command.c.

1041 functions. Affected file silcd/server.c.
1043 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1044 which ID was changed. This way the router will send the
1045 user list for the channel again, and server won't be in
1046 desync in some rare circumstances. Affected file is
1047 silcd/packet_receive.c.
1049 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1081 not to save the history information for clients. Same was
1082 fixed earlier in remove_clients_by_server function, but not
1083 here. Affected file silcd/packet_receive.c.
1085 * Raised the default connection-retry count from 4 to 7 in
1086 server. Affected file silcd/server.h.
1088 * Cancel any possible reconnect timeouts when we start the
1089 key exchange. Affected file silcd/server.c.
1091 * Do not reconnect on connection failure when SCONNECT was
1092 given. Affected files silcd/server.[ch].
1094 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1096 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1098 * Fixed the NICK command to always give the unformatted
1099 nickname to the one giving the NICK command. If unformatted
1100 nickname is cached already it will be formatted and the
1101 local entry will always get the unformatted nickname.
1102 Affected file lib/silcclient/idlist.c.
1104 * Fixed some double frees from client library commands.
1105 Affected file is lib/silcclient/command.c.
1107 * Fixed CUMODE command in server to assure that no one can
1108 change founder's mode than the founder itself, there was a
1109 little bug. Affected file silcd/command.c.
1111 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1113 * Removed the SilcClientCommandDestructor from the client
1114 libary, it is not needed anymore. Affected files are
1115 lib/silcclient/silcapi.h, command[_reply].[ch],
1116 client_notify, idlist.c.
1118 * Fixed GETKEY command to first resolve client, and then
1119 resolve the server only if the client was not found, instead
1120 of resolving both at the same time. Affected file is
1121 lib/silcclient/command.c.
1123 * Added silc_client_start_key_exchange_cb and lookup the
1124 remote hostname and IP address before starting the key
1125 exchange with server. The affected file is
1126 lib/silcclient/client.c.
1128 * The server's public key is now saved using the IP address
1129 of the server and not the servername for the filename.
1130 The hostname public key filename is checked as an fall back
1131 method if the IP address based filename is not found.
1133 Fixed the GETKEY command to save the fetched server key
1134 in correct filename.
1136 Print the remote server's hostname now when new key is
1137 received during connection process. Affected file is
1138 irssi/src/silc/core/client_ops.c.
1140 * Return always our own public key to the client if it asks
1141 for it with GETKEY command. Affected file silcd/command.c.
1143 * Removed the use_auto_addr variable from default config
1144 file since it was in wrong section. Affected file is
1147 * Fixed TOPIC_CHANGE notification to not route it when it
1148 was sent using silc_server_send_notify_to_channel function.
1149 Affected file silcd/command.c.
1151 * Fixed silc_server_send_notify_kicked to send the kicker's
1152 Client ID also, it was missing. Affected files are
1153 silcd/command.c, silcd/packet_send.[ch].
1155 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1157 * Do not save client history information in SERVER_SIGNOFF.
1158 Fixes the bug in normal server that it does not detect
1159 the client becoming valid after the server becomes back
1160 online. Affected file silcd/server_util.c.
1162 * Added `sock_error' field into the SilcSocketConnection
1163 context. When error occurs during socket operation (read
1164 or write) the error is saved. Added also new function
1165 silc_socket_get_error to return human readable socket error
1166 message. Affected files are lib/silcutil/silcsockconn.[ch],
1167 lib/silcutil/unix/silcunixsockconn.c, and
1168 lib/silcutil/win32/silcwin32sockconn.c.
1170 * The server now prints the socket error message in the
1171 signoff for client. Affected file silcd/server.c.
1173 * Fixed the `created' channel information sending from router
1174 to server in JOIN command. Checks now whether the channel
1175 really was created or not and set it according that.
1177 Fixed the JOIN command to use the client entry's current
1178 ID during the joining procedure instead of the one it sent
1179 in the command (it is checked though), since it can change
1180 between the packet processing and command processing, and
1181 would just case unnecessary pain in the client end. Affected
1182 file silcd/command.c.
1184 * Fixed a channel key payload sending to use correct channel
1185 ID when the server was forced to change the channel's ID by
1186 router. Router sent the key payload with the old Channel ID.
1187 Affected file silcd/packet_receive.c.
1189 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1191 * Call silc_server_save_channel_key only if the key payload
1192 was provided in the JOIN command's command reply. Affected
1193 file silcd/command_reply.c.
1195 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1197 * Fixed silc_mp_sizeinbase to return the value correctly with
1198 MPI. Affected file lib/silcmath/mp_mpi.c.
1200 * Fixed the stop_server signal to correctly stop the scheduler
1201 and gracefully stop the server when SIGTERM or SIGINT signals
1202 are received. Affected file silcd/silcd.c.
1204 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1206 * Simple handling of TERM and HUP signals. Also added some log
1207 flushing call around. Affected file is
1210 * Fixed small bugs in silclog.c. Now buffering output will take
1211 effect after 10 seconds since startup: This will ensure that
1212 no important startup messages are lost. Also output redirection
1213 will preserve original format ([Date] [Type] message).
1214 Affected file is lib/silcutil/silclog.c.
1216 * Added two options to the config file, in the logging section:
1217 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1218 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1220 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1222 * Do not print the warning about log files not being initialized
1223 more than once to avoid excess logging. Affected file is
1224 lib/silcutil/silclog.c.
1226 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1227 the SIM copying in make install in Makefile.am.pre.
1229 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1231 * Rewritten silclog APIs. Globally interesting changes follows:
1232 silc_log_set_files() changed to silc_log_set_file().
1233 silc_log_set_callbacks() changed to silc_log_set_callback().
1234 ROBOdoc documented silclog header file.
1235 SilcLogCb now returns bool to wether inihibit the default
1236 handler or not (to keep the old behaviour return always TRUE).
1237 The new APIs should also fix the problem of the
1238 silcd_error.log file that was written in the current directory.
1241 Log files streams will remain opened after silc_log_set_file()
1242 call, means less CPU usage notably on high traffic servers.
1243 File streams are now full buffered, and flushed to the disk
1244 every 5 minutes, lesses HD activity and CPU usage.
1245 Messages can be redirected, allowing admins to configure
1246 one single logfile for all server messages.
1247 the silc_log_quick global variable to activate fast-logging.
1248 Affected files lib/silcutil/silclog.[ch]
1250 * Changed some code to conform new silclog APIs. Affected
1251 files are doc/example_silcd.conf.in, silcd/server.c
1252 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1255 * Fixed a memory leak that could occur in some situations.
1256 Affected file silcd/serverconfig.c.
1258 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1260 * Added the silc_client_del_client to remove the client from
1261 all channels as well. Affected file lib/silcclient/idlist.c.
1263 * Fixed the client library to correctly remove the client
1264 from all channels when the client entry is being destroyed.
1265 Affected file lib/silcclient/client_notify.c, command.c.
1267 * Added auto-nicking support to the client library. If the
1268 applicatio now sets client->nickname it will be sent to the
1269 server after connecting by the library. This way for example
1270 SILCNICK (or IRCNICK) environment variables will have effect
1271 and always change the nickname automatically to whatever
1272 it is wanted. Affected file lib/silcclient/client.[ch].
1274 * Renamed silc_server_command_bad_chars to the
1275 silc_server_name_bad_chars and moved it to the
1276 silcd/server_util.[ch]. Added also new function
1277 silc_server_name_modify_bad to return nickname that
1278 includes bad characters as new nickname without those
1279 bad characters. This check and modify is now used in
1280 silc_server_new_client when the username is initially set
1281 as nickname, so it must be checked to be valid nickname.
1282 Affected file silcd/packet_receive.c.
1284 * The nickname length is now taken from the packet for real
1285 and not trusted to strlen() since it clearly can return
1286 wrong length for nickname including bad characters. This
1287 also applies to channel names. Affected file silcd/command.c.
1289 * Removed the lib/silcsilm/modules directory. Modules are now
1290 compiled into the lib/silcsim. Fixed the copying of the
1291 modules to follow symbolic links in Makefile.am.pre.
1293 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1295 * Fixed silc_string_regexify list creation. Fixes bugs with
1296 BAN and INVITE commands in server. The affected file is
1297 lib/silcutil/unix/silcunixutil.c.
1299 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1301 * Removed the command destructor entirely from the server's
1302 command and command reply routines. It is not needed, and
1303 its usage was buggy and caused crashes. Affected files are
1304 silcd/command[_reply].[ch].
1306 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1308 * Cancel protocol and NULL sock->protocol if timeout
1309 occurred during protocol. Affected file silcd/server.c.
1311 * Cancel protocol timeouts always before calling the final
1312 callback, to assure that after final callback is called
1313 no other state will be called for the protocol anymore.
1314 Affected file silcd/protocol.c.
1316 * Print error log if incoming connection configuration could
1317 not be found. Affected file silcd/server.c.
1319 * Fixed JOIN command to correctly save the founder mode
1320 to the client on normal SILC server, when the channel
1321 was created by the router. Affected file silcd/command.c.
1323 * Fixed LIST command (hopefully) to send correct reply
1324 packets. Affected file silcd/command.c.
1326 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * The silc_packet_receive_process now returns FALSE if the
1329 read data was invalid packet, and TRUE if it was ok.
1331 The server now checks that if unauthenticated connection
1332 sends data and its processing fails the server will close
1333 the connection since it could be a malicious flooder.
1335 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1337 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1339 * Make sure the warning about error opening a log file is
1340 printed only once and not everytime it fails (produces
1341 too much useless log). Affected file lib/silcutil/silclog.c.
1343 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1345 * Made the silc_server_daemonise() function more readable.
1346 Affected file silcd/server.c.
1348 * Pid file is now optional, the user may comment it out from
1349 the config file. Removed define SILC_SERVER_PID_FILE, we
1350 don't need a default any longer. Affected file
1351 configure.in.pre, lib/Makefile.am.pre.
1353 * Make some use of the pid file. The server now dies at startup
1354 if it detects a valid pid file on his path. The server would
1355 die anyway in this circumstance, because of the bind() failure.
1356 Affected file silcd/silcd.c.
1358 * No longer compiling lib/dotconf.
1360 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1362 * Fixed JOIN command parsing not to crash. Affected file
1363 lib/silcclient/command.c.
1365 * Fied the NICK_CHANGE notify to add the new client entry
1366 even it is resolved. This removes an <[unknown]> nick
1367 thingy bug in the client. Affected file is
1368 lib/silcclient/client_notify.c.
1370 * Do not try to allocate 0 bytes (efence does not like it)
1371 in lib/silccore/silccomand.c when encoding payload.
1373 * Do not take IRCNICK as nickname in Irssi SILC client since
1374 it is not possible to set nickname before hand connecting
1375 the server (TODO has an entry about adding auto-nicking
1378 * Changed the silc_server_command_pending to check whether
1379 there already exists an pending entry with the specified
1380 command, command identifier and pending callback. This is
1381 to fix IDENTIFY and WHOIS related crashes that may register
1382 multiple pending commands with same identifier. Affected
1383 file silcd/command.c.
1385 * Fixed the server to reconnect to the router even if it
1386 was already reconnecting and EOF was received. This to
1387 fix a possibility that the server wouldn't ever try to
1388 auto-reconnect to the router. Affected file silcd/server.c.
1390 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Fixed the server's password authentication to use the
1393 length of the locally saved password, and not the one
1394 sent in the packet. Affected file silcd/protocol.c.
1396 * Fixed same password authentication problem in the
1397 Authentication Payload handling routines in
1398 lib/silccore/silcauth.c.
1400 * Yet another password authentication problem fixed with
1401 channel password handling in silcd/command.c.
1403 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1405 * If first character of string in silc_parse_userfqdn is '@'
1406 then do not parse it. Affected file is
1407 lib/silcutil/silcutil.c.
1409 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Fixed minor bug in IDENTIFY command reply sending, which
1412 caused various weird problems during JOIN when it was
1413 resolving names for users. Affected file silcd/command.c.
1415 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Fixed the IDENTIFY command reply sending to chech better valid
1418 clients. It was possible to send incomplete list of replies.
1419 Affected file silcd/command.c.
1421 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1423 * Added silc_client_command[s]_[un]register functions now to
1424 dynamically register the commands in client library. Removed
1425 the static table of commands. This allows the client library
1426 to call commands without causing the application to know about
1427 what commands library has called.
1429 Removed the INFO command reply kludge to detect when the command
1430 was called by library. Now library use its own command reply
1431 function for INFO command.
1433 Added function silc_client_command_call to call a command.
1434 Application can use it to call command, not access the structure
1437 Now all commands that are sent by the client library (not
1438 explicitly sent by application) use own command reply functions.
1440 Affected files around lib/silcclient/ and in
1441 irssi/src/silc/core/.
1443 * Fixed the WHOIS command reply sending to chech better valid
1444 clients. It was possible to send incomplete list of replies.
1446 Fixed the WHOIS and IDENTIFY to send the request to router
1447 if normal server did not do it and did not find any results.
1449 Affected file silcd/command.c.
1451 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1453 * Moved the internal data from SilcClient context into its
1454 own file, not accesible to application. Affected files
1455 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1456 and other files in client library.
1458 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1460 * Added doc/examples installation target in Makefile.am.pre.
1463 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1465 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1466 commands the found client entry will be removed from the
1467 cache, after notifying application about the error. Affected
1468 file lib/silcclient/command_reply.c.
1470 * Changed the /MSG to check for exact nickname user gave, and
1471 not let `nick' match `nick@host' if it is only one found. Now,
1472 user must type the exact nickname (like nick@host2) even if
1473 there are no more than one same nicks found. This is to avoid
1474 a possibility of sending nickname to wrong nickname since
1475 `nick' could match `nick@host'. Affected file is
1476 irssi/src/core/silc-servers.c.
1478 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1480 * Do not print "you are now server operator" or similar when
1481 giving /away command. Affected files are
1482 irssi/src/silc/core/client_ops.c, silc-servers.h.
1484 * Made the silc_server_command_pending_error_check to send
1485 the same command reply payload it received back to the
1486 original sender of the command. This way all arguments
1487 that was received by the server will be received by the
1488 client too. Affected file silcd/command.c.
1490 * Added the silc_idcache_add to return the created cache entry
1491 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1493 * Add global clients to expire if they are not on any channel.
1494 This is because normal server will never know if they signoff
1495 if they are not on any channel. The cache expiry will take
1496 case of these entries. This is done by normal servers only.
1497 The affected files are silcd/command_reply.c,
1498 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1500 * If server receives invalid ID notification for WHOIS or
1501 IDENTIFY and the ID exists in the lists, it is removed.
1502 Affected file silcd/command_reply.c.
1504 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1505 in client then client entry that it matches is searched and
1506 the nickname is printed on the screen for user. Affected
1507 file irssi/src/silc/core/client_ops.c.
1509 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1511 * Use cache entry expire time in the LIST command reply to
1512 purge old entries from the cache after the LIST command
1513 reply has been received. This way we don't have non-existent
1514 entries in the cache for too long. Affected file is
1515 silcd/command_reply.c.
1517 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * If we are normal server, and we've not resolved client info
1520 in WHOIS or IDENTIFY from router, and it is global client,
1521 we'll check whether it is on some channel. If it is not
1522 then we cannot be sure about its validity and will resolve it
1523 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1524 file silcd/command.c.
1526 * Search channel by name (if possible) rather than by ID
1527 in IDENTIFY command's command reply. Affected file is
1528 silcd/command_reply.c.
1530 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1533 Updated specs and implemented it. Affected file silcd/command.c,
1534 silcd/packet_send.c and silcd/packet_receive.c.
1536 * Implemented the <founder auth> payload handling in the JOIN
1537 command. If provided all conditions for channel joining
1538 except requirement to provide correct passphrase can be
1539 overrided by the channel founder. Updated the protocol specs.
1540 Affected file silcd/command.c.
1542 Added support for founder auth in JOIN command in client
1543 library. Fixed the parsing of the JOIN command now to support
1544 all options as they should be. The affected file is
1545 lib/silcclient/command.c.
1547 * Optimized the WHOIS and IDENTIFY commands to send the request
1548 to router only if it includes nicknames or other names. If
1549 they include only IDs then check the local cache first before
1550 routing. Affected file is silcd/command.c.
1552 * Added channels topic announcements. Affected file is
1553 silcd/packet_receive.c and silcd/server.c.
1555 * Fixed the silc_server_send_notify_topic_set to really destine
1556 the packet to channel. Affected file silcd/packet_send.c.
1558 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1559 library. Affected file lib/silcclient/client_notify.c.
1561 * Added UMODE announcements. Affected file silcd/server.c.
1563 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Memory leak fixes in:
1567 lib/silcutil/silcsockconn.c
1568 lib/silcske/silcske.c
1569 lib/silcske/groups.c
1571 lib/silccrypt/silcpkcs.c
1572 lib/silccore/silccommand.c
1573 lib/silccore/silcidcache.c
1578 * ROBOdoc documented the lib/silcske/groups.h file and a
1579 bit changed the interface for better.
1581 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1583 * Update the client entry context in the ID cache after
1584 nick change. Affected file lib/silcclient/command.c.
1585 Fixes the CUMODE command when regaining founder privileges,
1586 and a little WHOIS problem.
1588 * Fixed silc_net_gethostbyname to correctly call the
1589 inet_ntop. Affected file lib/silcutil/silcnet.c.
1591 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1593 * Added IPv6 support checking to the configure.in.pre, added
1594 also --enable-ipv6 option to override the check. Affected
1595 file configure.in.pre.
1597 * The silc_thread_create now calls the start function
1598 directly if threads support is not compiled in. Removes
1599 ugly #ifdef's from generic code. Affected files are
1600 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1602 * Added silc_net_gethostby[name/addr]_async to asynchronously
1603 resolve. Affected files are lib/silcutil/silcnet.[ch].
1605 * Added support for rendering IPv6 based server, client and
1606 channel IDs. Affected file lib/silcutil/silcutil.c.
1608 * Added support for creating IPv6 based server IDs. Affected
1609 file is silcd/serverid.c.
1611 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1613 * Added silc_net_gethostby[addr/name] into the
1614 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1615 routines. Added silc_net_is_ip[4/6]. Affected file is
1616 lib/silcutil/unix/silcunixnet.c. All routines that take
1617 address as argument now supports both IPv4 and IPv6 addresses.
1619 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1621 * Fixed LIST command reply sending in server. Affected file
1624 * Server now sends the kicker's client ID in the KICK notify
1625 to the kicked client. Affected file silcd/command.c.
1627 * The client library now parses the kickers client ID and
1628 UI displays it. Affected files lib/silcclient/client_notify.c
1629 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1631 * Made all payload parsing function prototypes consistent.
1632 They all take now const unsigned char * and uint32 pair as
1633 the payload data instead of SilcBuffer. Changes all around
1634 the source tree. Other unsigned char* -> const unsigned char*
1635 changes around the tree as well.
1637 * Optimized SFTP client and server packet sending not to
1638 allocate new buffer for each packet but to recycle the
1639 first allocated buffer. Affected files are
1640 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1642 * Optimized the SFTP client to use SilcList instead of
1643 SilcDList for requests, because it is faster. Affected file
1644 is lib/silcsftp/sftp_client.c.
1646 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1647 into lib/silccore/silcid.[ch].
1649 Renamed silcpayload.[ch] into silcargument.[ch].
1651 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * If client entry is deleted with active key agreement
1654 session, abort the session.
1656 The silc_client_abort_key_agreement now calls the completion
1657 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1659 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1662 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1664 * Don't use __restrict in older GCC's. Affected file is
1665 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1667 * silc_net_localhost now attempts to reverse lookup the
1668 IP/hostname. Affected file lib/silcutil/silcnet.c.
1670 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1671 command. It can be used to gain founder privileges at
1672 the same time when joining the channel.
1674 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1675 kicker's client ID as well. Updated protocol specs.
1677 Defined that the server must send SILC_COMMAND_IDENTIFY
1678 command reply with error status to client who sent
1679 private message with invalid client ID.
1681 Updated the protocol specification.
1683 * Added silc_server_send_command_reply to send any
1684 command reply. Affected file silcd/packet_send.[ch].
1686 * Added silc_id_payload_encode_data to encode ID payload
1687 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1689 * The server now send IDENTIFY command reply with error
1690 status if client ID in private message is invalid. Affected
1691 file silcd/packet_receive.c.
1693 * Save the server key file with server's IP address in
1694 the filename instead of hostname. The affected file is
1695 irssi/src/silc/core/client_ops.c.
1697 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1699 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1702 * Added libtool support for compiling shared objects in
1703 lib/silcsim. Affected file configure.in.pre and
1704 lib/silcsim/Makefile.am. Original patch by cras.
1706 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Pid file configuration, and server's config file fixes
1709 patch by toma. Updated CREDITS file.
1711 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1713 * Fixed silc_client_channel_message to not try to decrypt
1714 the message twice if it resolved the destination client
1715 information. This could cause of dropping one channel
1716 message. Affected file lib/silcclient/client_channel.c.
1718 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1721 lib/silcclient/client.c. This function is used when the SILC
1722 Client is run under some other scheduler, or event loop or
1723 main loop. On GUI applications, for example this may be
1724 desired to used to run the client under the GUI application's
1725 main loop. Typically the GUI application would register an
1726 idle task that calls this function multiple times in a second
1727 to quickly process the SILC specific data.
1729 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1731 * Fixed silc_server_drop() for dropping the supplementary
1732 groups as well, this could cause a security hole on some
1735 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1737 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1740 * Write PID file after dropping privileges. Added -F option
1741 to run server on foreground. A patch by debolaz.
1742 Affected files silcd/server.c, silcd/silcd.c.
1744 * Fixed MOTD to return the MOTD file server name. Affected
1745 file silcd/command.c.
1747 * Added INFO command reply handling to the Irssi SILC Client.
1748 Affected file irssi/src/silc/core/client_ops.c.
1750 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1752 * Fixed the silc_idcache_list_* routines to really support
1753 the dynamic list. Fixes a crash. Affected file is
1754 lib/silccore/silcidcache.c.
1756 * Fixed the LIST command reply to really call LIST command's
1757 pending callbacks. Affected file silcd/command_reply.c.
1759 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1761 * Update conn->local_entry->nickname after giving NICK
1762 command. Affected file lib/silcclient/command.c.
1764 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1766 * Added the [pid] option to the silcd configuration file
1768 Affected files: serverconfig.[ch] and silcd.c
1770 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1772 * Save fingerprint in WHOIS command reply in server.
1773 Affected file silcd/command_reply.c.
1775 * Fixed NICK commands pending callback registration.
1776 Affected file lib/silcclient/command.c.
1778 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * Use ++server->cmd_ident when sending commands in server,
1781 instead of random number. Affected file silcd/command.c.
1783 * Fixed GETKEY command reply to call actually GETKEY pending
1784 command callbacks. Affected file silcd/command_reply.c.
1786 * A bit stricter check for nicknames. Check for same nickname
1787 in NICK command also. Affected file silcd/command.c.
1789 * Do not call INFO command everytime client ID changes, only
1790 during first connecting. Affected file lib/silcclient/client.c.
1792 * Set the new nickname only after successful command reply for
1793 NICK command is returned by server. Affected file
1794 lib/silcclient/command.c.
1796 * Remove nicknames from nicklist during server_signoff notify.
1797 Should fix /NAMES bit more. The affected file is
1798 irssi/src/silc/core/silc-channels.c.
1800 * Added `fingerprint' field to the SilcIDListData in the
1801 silcd/idlist.h to hold the fingerprint of the client's
1804 Send the fingerprint of the client's public key in WHOIS
1807 Affected files silcd/command.c, and silcd/idlist.[ch].
1809 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1810 create fingerprint from given data.
1812 * Show the fingerprint of the client's public key in WHOIS.
1813 Affected files irssi/src/module-formats.[ch] and
1814 irssi/src/silc/core/client_ops.c.
1816 * Format the multiple same nicknames also during JOIN and
1817 NICK_CHANGE notifys. Affected file is
1818 lib/silcclient/client_notify.c.
1820 * Do not print error on screen for invalid private message
1821 payload since it can come if someone is sending private
1822 messages with wrong key. Affected file
1823 lib/silccore/silcprivate.c.
1825 * Fixed multiple concurrent /PING crash. Affected file
1826 lib/silcclient/command.c.
1828 * Changed the wrong ID encoding. All IP addresses must be
1829 in MSB first order in encoded format. They were encoded
1830 wrong and was in LSB format. Affected files are
1831 silcd/serverid.c, lib/silcutil/silcutil.c.
1833 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1835 * Call the `connect' client operation through the scheduler
1836 in case of error. Affected file lib/silcclient/client.c.
1838 * Call the `failure' client operation even if the error
1839 occurred locally during a protocol. Affected file is
1840 lib/silcclient/protocol.c.
1842 * Added support of sending LIST command to router from normal
1843 server. This way normal server can get list of all channels
1844 in the network too. Fixed the channel list sending in the
1845 server too. Affected files are silcd/command.c, and
1846 silcd/command_reply.[ch].
1848 * Added silc_server_update_channels_by_server and
1849 silc_server_remove_channels_by_server. They are used during
1850 disconnection of primary router and in backup router protocol.
1851 Affected file silcd/server_util.[ch], silcd/server.c and
1852 silcd/server_backup.c.
1854 * Fixed channel adding to global list in IDENTIFY command
1855 reply in server. Affected file silcd/command_reply.c.
1857 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1859 * If the incoming packet type is REKEY or REKEY_DONE process
1860 that packet always synchronously. Fixes yet another MAC
1861 failed error on slow (dialup) connections. Affected file
1862 lib/silcclient/client.c and silcd/server.c.
1864 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1866 * Call check_version SKE callback for initiator too. Affected
1867 file lib/silcske/silcske.c.
1869 * Implemented fix for security hole found in the SKE that was
1870 fixed in the specification few days back; the initiator's
1871 public key is now added to the HASH value computation.
1872 Added backwards support for the old way of doing it too, for
1873 old clients and old servers. Affected file is
1874 lib/silcske/silcske.c.
1876 * Enabled mutual authentication by default in SKE. If initiator
1877 is not providing mutual authentication the responder will
1878 force it. This will provide the proof of posession of the
1879 private key for responder. The affected files are
1880 lib/silcclient/protocol.c and silcd/protocol.c.
1882 * Do not cache anymore the server's public key during SKE.
1883 We do mutual authentication so the proof of posession of
1884 private key is done, and if the server is authenticated in
1885 conn auth protocol with public key we must have the public
1886 key already. Affected file silcd/protocol.c.
1888 * Added new global debug variable: silc_debug_hexdump. If
1889 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1890 file lib/silcutil/silclog.[ch].
1892 * Fixed compilation warning due to char * -> const char *.
1893 Affected files lib/silcutil/silcnet.h, and
1894 lib/silccore/silcauth.[ch].
1896 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * Fixed CMODE command when new channel key was created. If
1899 the creation failed the old key was removed. Next time giving
1900 same command would crash the server since the old key was
1901 freed already. Affected file silcd/command.c.
1903 * Fixed the silc_server_announce_get_channels to not crash
1904 on reconnect. Affected file silcd/server.c.
1906 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1908 * Added silc_log_set_debug_string function to set a regex
1909 string to match for debug output. Only the function names,
1910 or filenames matching the given debug string is actually
1911 printed. This way it is possible to filter out those debug
1912 strings that user is not interested in.
1914 Fixed a bug in silc_string_regexify.
1916 Affected files lib/silcutil/silclog.[ch], and
1917 lib/silcutil/unix/silcunixutil.c.
1919 * Changed the -d options in both server and Irssi SILC client
1920 to take the debug string as argument. Affected files
1921 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1923 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Added silc_hash_babbleprint to create a Bubble Babble
1926 Encoded fingerprint. The encoding is developed by Antti
1927 Huima (draft-huima-babble-01.txt), and it creates human
1928 readable strings out of binary data. Affected file
1929 lib/silccrypt/silchash.[ch].
1931 * Print the babble print now in addition of fingerprint as well
1932 in Irssi SILC client. Affected files are
1933 irssi/src/fe-common/silc/module-formats.[ch],
1934 irssi/src/fe-common/silc/core/client_ops.c.
1936 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * Fixed a security problem found in SKE. The initiator's
1939 public key too is now added to the HASH hash value creation
1940 which is signed by the responder to create the SIGN value.
1941 This will prevent anyone in the middle to lie to the responder
1942 about the initiator's public key. If this is done now, the
1943 man in the middle will get caught. Updated the protocol
1946 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1948 * Better installation directory handling. Configure module
1949 paths and other paths automatically to example_silc* files
1950 in doc/. A patch by toma.
1952 * Fixed compiler warning from MPI library, and from SILC RNG.
1955 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1956 It can be configured with ./configure. A patch by toma.
1958 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1960 * Find correct make to use in prepare-clean. A patch by
1961 toma. Affected file prepare-clean.
1963 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1965 * Added irssi variables use_auto_addr, auto_bind_ip,
1966 auto_bind_port and auto_public_ip.
1968 * Changed the interface for silc_client_send_key_agreement
1969 in lib/silcclient/silcapi.h
1973 irssi/src/silc/core/silc-core.c
1975 lib/silcclient/silcapi.h
1976 irssi/src/silc/core/silc-channels.c
1977 lib/silcclient/client_keyagr.c
1980 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1982 * Added silc_pkcs_public_key_compare to compare two
1983 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1985 * Check that the client who set the founder mode on the
1986 channel is the same client that is giving the founder
1987 mode to itself. It is done by comparing the saved public
1988 key (it is saved even in the authentication is passphrase).
1989 Affected file silcd/command.c.
1991 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Do not process packet for disconnected socket connection.
1994 Affected file lib/silccore/silcpacket.c.
1996 * Process the DISCONNECT packet through scheduler in the
1997 client library. Affected file lib/silcclient/client.c.
1999 * Fixed the silc_client_packet_parse to not to increase
2000 the packet sequence number if the conn->sock and the
2001 current socket connection is not same. This can happen
2002 for example during key agreement when the conn includes
2003 multiple socket connections (listeners). Affected file
2004 lib/silcclient/client.c.
2006 * The sender of the file transfer request now provides also
2007 the pointer (listener) for the key exchange protocol. If
2008 the listener cannot be created then it sends empty key
2009 agreement and lets the receiver provide the listener.
2011 Added `local_ip' and `local_port' arguments to the
2012 silc_client_file_send. If they are provided they are used,
2013 if not then it will attempt to find local IP address, if
2014 not found or bind fails then the remote client will provide
2017 Affected files are lib/silcclient/client_ftp.c and
2018 lib/silcclient/silcapi.h.
2020 * Extended the FILE SEND command to support defining the
2021 local IP and port for key exchange listener. They are
2022 optional. Affected file irssi/src/silc/core/silc-servers.c.
2024 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2026 * Defined to WHOIS command reply the sending of fingerprint
2027 of the client's public key (if the proof of posession of the
2028 corresponding private key is verified by the server).
2029 Updated to the protocol specification.
2031 * Added support of receiving the client's public key's
2032 fingerprint in command reply in client library. Affected
2033 file is lib/silcclient/command_reply.c, and
2034 lib/silcclient/idlist.[ch].
2036 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2038 * Do not send over 128 chars long nickname to the server
2039 in NICK command. Affected file lib/silcclient/command.c.
2041 * Do not send over 256 chars long channel names to the server
2042 in JOIN command. Affected file lib/silcclient/command.c.
2044 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Assure that silc_server_close_connection cannot be called
2047 twice for same socket context. Affected file is
2050 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2052 * Send error message to application if opening file for
2053 writing during file transfer fails. Affected file is
2054 lib/silcclient/client_ftp.c.
2056 Remove all file transfer sessions for a client that we're
2057 removing from ID cache.
2059 Affected file is lib/silcclient/client_ftp.c.
2061 * Fixed silc_net_addr2bin to return correct address. Affected
2062 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2064 * Fixed file transfer session removing on signoff notify.
2065 Affected file irssi/src/silc/core/silc-servers.c.
2067 * Added the SilcClientFileError to be returned in the monitor
2068 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2069 Affected file lib/silcclient/silcapi.h.
2071 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * Fixed a crash in silc_client_ftp_free_sessions and
2074 silc_client_ftp_session_free_client. Affected file
2075 lib/silcclient/client_ftp.c.
2077 * Added `disabled' field in the SilcChannelEntry in the server
2078 to indicate if the server entry is disabled. Affected file
2079 silcd/idlist.h, silcd/command[_reply].c.
2081 * SILC server adds now /var/run/silcd.pid everytime it is
2082 started. Affected file silcd/silcd.c.
2084 * Added silc_server_packet_send_clients to send a packet to
2085 the provided table of client entries. Affected file
2086 silcd/packet_send.[ch].
2088 * Fixed a crash in client resolving in client_prvmsg.c in
2089 client library. Affected file lib/silcclient/client_prvmsg.c.
2091 * Do not actually remove the client directly from ID cache
2092 during SERVER_SIGNOFF, but invalidate it. This way we
2093 preserve the WHOWAS info for the client. Affected file
2094 silcd/server_util.c.
2096 * Fixed SERVER_SIGNOFF notify handling in the server. The
2097 server is now able to process incoming SERVER_SIGNOFF notify
2098 for a server that it doesn't even know about. It will remove
2099 the clients provided in the notify. Affected file
2100 silcd/packet_receive.c.
2102 * Check for partial packet in data queue after every packet that
2103 was found from the queue. Return and wait for more data if
2104 there is partial data in queue. Affected file is
2105 lib/silccore/silcpacket.c.
2107 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Added SilcClietFileError enum to indicate error in
2110 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2111 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2112 Affected files lib/silcclient/silcapi.h and
2113 lib/silcclient/client_ftp.c.
2115 * Check that newsize in silc_buffer_realloc is larger than
2116 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2118 * Added better monitor of file transfers. It now monitors
2119 key agreement protocol during the file transfer too. Added
2120 error reporting too. Affected files
2121 irssi/src/silc/core/silc-servers.c,
2122 irssi/src/fe-common/silc/module-formats.[ch].
2124 * Wrote a help file for FILE command.
2126 * Added silc_rng_global_get_byte_fast to get not-so-secure
2127 random data as fast as possible. Random data is read from
2128 /dev/urandom if available and from the SILC RNG if not
2129 available. It is used in padding generation. Affected file
2130 lib/silccrypt/silcrng.[ch].
2132 * All packets in client library are now processed synchronously.
2133 Optimized packet processing a lot. Affected file
2134 lib/silcclient/client.c.
2136 * All server connection packets are processing synchronously
2137 now in server, to optimize packet processing. Affected file
2140 * Include files are installed now only in Toolkit distribution
2141 if make install is given. Affected files: all Makefile.am's.
2143 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2145 * Assure that silc_client_notify_by_server_resolve does not
2146 resolve the client information multiple times. If it cannot
2147 be found by the first it cannot be found at all. Affected
2148 file lib/silcclient/client_notify.c.
2150 * Fixed WHOWAS command reply calling. Affected file
2151 lib/silcclient/command_reply.c.
2153 * Removed all references to silc_idlist_get_client from the
2154 Irssi SILC client since that call is internal call used by
2155 the library. The Irssi SILC client will use now client
2156 retrieval functions found in silcapi.h.
2158 * Fixed a bug in resolving nickname info before sending
2159 private message. It used freed memory. Affected file
2160 irssi/src/silc/core/silc-servers.c.

2181 * Added silc_net_localip to return local host's IP address.
2182 Affected file lib/silcutil/silcnet.[ch].
2184 * If key exchange or rekey protocol is active for a connection
2185 parse all packets syncronously since there might be packets
2186 in packet queue that we are not able to process without first
2187 processing packets before them. Affected file silcd/server,
2188 lib/silcclient/client.c.
2190 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2191 whether library should continue processing the packet.
2192 Affected file lib/silccore/silcpacket.h.

2227 * Resolve the client info when received private message or
2228 channel message for a client which nickname we don't know.
2229 Affected files lib/silcclient/client_prvmsg.c and
2230 lib/silcclient/client_channel.c.
2232 * Do not crash in /KEY if client is not connected. Affected
2233 file irssi/src/silc/core/silc-channels.c.

2238 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2239 is incomplete and is being resolved, it won't be resolved
2242 Make sure also that USERS command reply does not resolve
2243 twice information. Affected file is
2244 lib/silcclient/command_reply.c.
2246 Make sure that silc_client_get_clients_by_list does not
2247 resolve twice same information.
2249 * Check for valid client->id in the silc_server_free_client_data.
2250 Affected file silcd/server.c.
2252 * Fixed /GETKEY nick@server not to crash if the server entry
2253 is not found. Affected file lib/silcclient/command.c.
2255 * Fixed the silc_server_check_cmode_rights to check the
2256 requested modes correctly. Affected file silcd/command.c.

2260 * Better checks for non-printable chars in nick added.
2261 Affected file silcd/command.c.
2263 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2265 * Call the silc_server_udpate_servers_by_server in the
2266 primary router that comes back online in the backup resuming
2267 protocol. Otherwise it routes packets wrong. Affected file
2268 silcd/server_util.[ch], silcd/server_backup.c.
2270 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2272 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2273 lib/silcutil/silcbuffmt.[ch].
2275 * Redefined the SILC packet header to include the padding
2276 length. Affected file lib/silccore/silcpacket.[ch].
2278 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2279 length for maximum padding up to 128 bytes). Affected
2280 file lib/silccore/silcpacket.h.
2282 * Removed all backwards support for old 0.5.x MAC thingies.
2283 The SILC packet header change makes it impossible to be
2284 backwards compatible.
2286 * Send the ENDING packet with timeout in the backup resuming
2287 protocol. This is to assure that all routers has connected
2288 to the primary router. Affected file silcd/server_backup.c.
2290 * Changed the RNG to take the first IV from random data. It
2291 used to take it from zero actually. Changed the RNG also
2292 to use /dev/urandom during session. /dev/random is used
2293 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2295 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2297 * Changed the SILC packet header to have the first two bytes
2298 (the packet length) encrypted. Affected files aroung the
2299 code tree, lib/silccore/silcpacket.[ch]. Removed the
2300 SilcPacketCheckDecrypt callback. It is not needed anymore
2301 since the silc_packet_receive_process will determine now
2302 whether the packet is normal or special.
2304 * Implemented the unidirectional MAC keys. Affected files
2305 lib/silcske/silcske.c, silcd/protocol.c and
2306 lib/silcclient/protocol.c.
2308 * Implemented the packet sequence number to the MAC computation.
2309 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2310 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2311 lib/silcclient/protocol.c.
2313 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2315 * Allow backup router to announce servers. All servers
2316 announced by backup router are added to the global list
2317 automatically. Update hte server's socket to our primary
2318 router also when backup router announces a server.
2319 Affected file silcd/packet_receive.c.
2321 * Do not update the client->router in the function
2322 silc_server_udpate_clients_by_server if the client is on
2323 global list. We might fail to find any specific server
2324 for locally connected clients and local cell clients. They
2325 should still use the `from' and not `to' as client->router.
2326 This fixes backup router resuming protocol. Affected file
2327 silcd/server_util.c.
2329 * Decrease channel statistics count only if the channel
2330 deletion worked. Affected files are silcd/server.c and
2331 silcd/server_util.c.
2333 * Added silc_server_update_servers_by_server to update origin
2334 of all server entries. Used during backup router protocol.
2335 Affected files silcd/server_util.[ch], silcd/server.c. and
2336 silcd/backup_router.c.
2338 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2339 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2340 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2341 lib/silccrypt/silchmac.c.
2343 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Assure that router cannot reroute the same channel message
2346 to the sender. Affected file silcd/packet_receive.c.
2348 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2350 * Made better checks that the channel message is not sent
2351 to the router it came from. Affected file is
2352 silcd/packet_send.c. Fixed memory leak too.
2354 * Announce informations for incoming router connection, but
2355 only after checking if it is replaced by backup router.
2356 Affected file silcd/packet_receive.c.
2358 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Fixed the backup resuming protocol to work in multiple
2361 router environment. Affected file silcd/server_backup.c.
2363 * Route packet only to one router in the function
2364 silc_server_packet_send_to_channel. Affected file is
2365 silcd/packet_send.c.
2367 * Fixed silc_server_send_notify_dest to set the broadcast
2368 flag. Fixed the silc_server_send_notify_topic to actually
2369 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2370 Affected file silcd/packet_send.c.
2372 * Changed the SFTP Filesystem interface. Changed the
2373 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2374 the filesystem operation function. The SilcSFTPFilesystem
2375 is now a context that is allocated by all filesystem allocation
2376 functions and it already includes the operations structure
2377 and filesystem specific context. It is given as argument
2378 now to the silc_sftp_server_start. This made the interface
2379 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2380 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2382 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Changed the backup router adding and getting interfaces
2385 in the server. The router that will be replaced by the
2386 specified backup router is now sent as argument. Affected
2387 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2390 * Added silc_net_addr2bin_ne to return the binary form of
2391 the IP address in network byte order. Affected files
2392 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2394 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Check for existing server ID in silc_server_new_server
2397 and in silc_server_connect_to_router_final and remove the
2398 old entry if it exists. Affected file silcd/packet_receive.c,
2401 * Send the channel message always to only one router, either
2402 in upstream or downstream. Affected file is
2403 silcd/packet_send.c.
2405 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2407 * Wrote the definition of the backup resuming protocol to the
2408 protocol specification.
2410 * Removed one redundant channel key generation from normal
2411 server during joining procedure. Removed one redundant
2412 channel key sending from server to router during joining
2413 procedure. Affected file silcd/command.c.
2415 * Made minor bugfixes to the backup router resuming protocol.
2416 Affected file silcd/server_backup.c, server.c.

2421 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2424 * Implemented the backup resuming protocol that is used to
2425 resume the primary router position in the cell after the
2426 primary router comes back online. Affected files
2427 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2428 and silcd/server_util.[ch].
2430 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2432 * Sleep two (2) seconds after sending QUIT command to server.
2433 Affected file lib/silcclient/command.c.
2435 * Assure that if outgoing data buffer is pending do not force
2436 send any data. Affected file silcd/packet_send.c.
2438 * Assure that if outgoing data buffer is pending do not force
2439 send any data. Affected file lib/silcclient/client.c.
2441 * Implemented the backup router support when the primary router
2442 goes down. The servers and routers can now use the backup
2443 router as new primary router without loosing connectivity.
2445 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2447 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2448 in the server to indicate disabled entry. All data read
2449 from the connection will be ignored and no data is sent
2450 for entry that is disabled. Affected files are
2451 silcd/idlist.h, silcd/server.c.
2453 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Created SFTP client and server test programs in the
2456 lib/silcsftp/tests directory.

2460 * Implemented memory filesystem (virtual filesystem) for
2461 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2464 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2466 * Implemented the SFTP (SSH File Transfer Protocol) to the
2467 lib/silcsftp. It includes SFTP client and SFTP server
2470 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2472 * Moved lib/silccore/silcprotocol.[ch] to the
2473 lib/silcutil library.
2475 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2476 take variable argument list pointer as argument. Affected
2477 file lib/silcutil/silcbuffmt.[ch].
2479 * Added silc_buffer_set function that is used to set data
2480 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2481 Affected file lib/silcutil/silcbuffer.h.
2483 * Changed various routines in the core library to use the new
2484 silc_buffer_set instead of allocating new buffer only for
2487 * Added 64-bit value formatting and unformatting support to the
2488 silc_buffer_[un]format routines. Affected file is
2489 lib/silcutil/silcbuffmt.[ch].
2491 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2492 to includes/bitmove.h.
2494 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Fixed channel user mode saving in client library. Affected
2497 file lib/silcclient/command[_reply].c.
2499 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Defined the file transfer to the SILC Protocol. Added
2502 new packet type SILC_PACKET_FTP and defined File Transfer
2503 Payload. The mandatory file transfer protocol is SFTP
2504 (SSH File Transfer Protocol). Affected file in addition
2505 of the internet draft is lib/silccore/silcpacket.h.
2507 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2508 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2509 is used as part of backup router protocol when the primary
2510 router of the cell is back online and wishes to resume
2511 the position as primary router.
2513 * Redefined the MAC generation keys in the protocol. The
2514 same key is not used anymore in both direction. Both
2515 direction will now use different keys for sending and
2516 receiving. This fixes a potential security flaw. This
2517 change causes incompatibilities in the protocol.
2519 * Redefined also the MAC computation from the packet.
2520 An packet sequence number is now added to the MAC
2521 computation. This prevents possible replay attacks against
2522 the protocol. This change too causes incompatibilities
2525 Added `sequence' field to the SilcPacketContext to hold
2526 the current sequence number for the packet.
2528 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2530 * Added `created' field to the SilcIDListData in the file
2531 silcd/idlist.h to indicate the time when the entry was
2534 * Added `created' field to the SilcChannelEntry too. Affected
2535 file silcd/idlist.h.
2537 * Added `creation_time' aguments to all the announcement functions
2538 in the server. If it is provided then only the entries that
2539 was created after the provided time frame are actually
2540 announced. Affected file silcd/server.[ch].
2542 * The protocol says that the Channel ID's IP address must be
2543 based on the router's IP address. Added check for this in
2544 the silc_server_new_channel when processing incoming New Channel
2545 Payload. Affected file silcd/packet_receive.c.
2547 * Print out the correct version with --version in SILC client.
2548 Affected file irssi/src/silc/core/silc-core.c.
2550 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2552 * Fixed WHOWAS command to check for completnes of the client
2553 entry always, not just when the command is coming from client.
2554 Affected file silcd/command.c.
2556 * Added new function silc_server_packet_queue_purge to purge the
2557 outgoing data queue to the network. After the function returns
2558 it is guaranteed that the outgoing packet queue is empty.
2559 Affected file silcd/packet_send.[ch].
2561 * Purge the outgoing packet queue in the rekey protocol's final
2562 callback to assure that all rekey packets go to the network
2563 before quitting the protocol. Affected file silcd/server.c.
2565 * Added silc_client_packet_queue_parse as similar function as
2566 in server to the client library. The affected file is
2567 lib/silcclient/client.c.
2569 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Splitted silcd/server.c and created silcd/server_util.[ch]
2572 for utility functions.
2574 * Added new socket flag SILC_SF_DISABLED to indicate that the
2575 connection is open but nothing can be sent to or received from
2576 the connection. Affected file lib/silcutil/silsockconn.[ch].
2577 The checking for disabled socket is checked in the low level
2578 silc_socket_write and silc_socket_read functions.
2580 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Allow only nicknames and channel names that fits into the
2583 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2585 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * When processing JOIN command reply in server check that if
2588 the channel exists in our global list we'll move it the local
2589 list. Affected file silcd/command_reply.c.
2591 * Fixed the check whether client is joined on the channel already
2592 in JOIN command. Affected file lib/silcclient/command.c.
2594 * Fixed the JOIN command reply to check whether the channel
2595 already exists. Affected file lib/silcclient/command_reply.c.
2597 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * Added silc_ske_status_string to map the SKE error numbers
2600 to readable strings. The affected files are
2601 lib/silcske/silcske[_status].[ch].
2603 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Do not show the private channels on the WHOIS channel list
2606 as it is not allowed by the protocol. The affected file is
2609 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Assure that the packet length digged from the actual packet
2612 is something sensible in the silc_packet_decrypt_rest_special
2613 in lib/silccrypt/silcpacket.c.
2615 * Free and NULL the allocated pointer in silc_hmac_alloc if
2616 the HMAC allocation fails. The affected file is
2617 lib/silccrypt/silchmac.c.
2619 * Print the selected security properties to the log files in
2620 the server. Affected file silcd/protocol.c.
2622 * Add SKE's reference counter even if calling the completion
2623 callback manually. Otherwise it goes negative, although it
2624 does not cause any problems. The affected file is
2625 lib/silcske/silcske.c.
2627 * Remove the client entry with short timeout after giving the
2628 KILL command. Affected file lib/silcclient/command.c.
2630 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2631 case all found clients are already disconnected (WHOWAS would
2632 found them) in the server. Affected file silcd/command.c.
2634 * Update the last_receive (time of last data received) to be
2635 updated only when received private or channel message so that
2636 the idle time showed in WHOIS makes more sense.
2638 * Added boolean field `valid' in to the SilcClientEntry in the
2639 client library to indicate whether the entry is valid or not.
2640 This fixes the nickname change bug on channel when changing
2641 the nickname to be same than the old (like nick to Nick) the
2642 nickname formatter doesn't set the new nick anymore to Nick@host.
2643 Affected file lib/silcclient/idlist.[ch].
2645 * Now actually fixed the nickname changing on disconnection.
2646 Added new function silc_change_nick to the Irssi SILC Client.
2647 Affected file irssi/src/silc/core/client_ops.c,
2648 irssi/src/silc/core/silc-nicklist.[ch].
2650 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2652 * Check that the public key exists in the GETKEY command before
2653 trying to encode it. Affected file silcd/command.c.
2655 * Print some notifications on received public keys with GETKEY
2656 command in the Irssi SILC Client. Affected files are
2657 irssi/src/fe-common/silc/module-formats.[ch],
2658 irssi/src/silc/core/client_ops.c.
2660 * Use IDENTIFY command to resolve the server information in the
2661 GETKEY command instead of INFO command. Affected file
2662 lib/silcclient/command.c.
2664 * All command reply functions in the client library now calls
2665 the pending command reply callbacks even if an error has
2666 occurred. The server has done this a long time and now it was
2667 time to move the client library to this as well. Now all
2668 errors can be delivered back to the pending command reply
2669 callbacks if necessary. Affected files are
2670 lib/silcclient/command[_reply].[ch].
2672 * Change the nickname on disconnection back to the username
2673 because in reconnect the server will enforce it to it anyway.
2674 Affected file irssi/src/silc/core/silc-servers.c.
2676 * Fixed a config file parsing bug in the Irssi SILC client.
2677 Affected file irssi/src/silc/core/clientconfig.c.
2679 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2681 * When printing the channel mode on JOIN, verify that the
2682 channel key and channel's HMAC are valid. Affected file
2683 irssi/src/silc/core/client_ops.c.
2685 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2687 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2688 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2689 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2691 * Removed channel key rekey task deleting from the function
2692 silc_server_save_channel_key. Affected file silcd/server.c.
2693 Added explicit timeout task context instead that is used to
2694 delete the task if we are registering a new task before the
2695 new task has elapsed.
2697 * When channel key rekey occurs the client library now saves
2698 the old channel key for a short period of time (10 seconds) and
2699 is able to use it in case some is still sending channel
2700 messages encrypted with the old key after the rekey. Affected
2701 file lib/silcclient/[idlist.h|client_channel.c].
2703 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2705 * Added check to the silc_server_new_id_real to not accept
2706 new ID if it is the sender's own ID. Affected file is
2707 silcd/packet_receive.c.
2709 * Assure that we do not announce ourself or the one we've
2710 sending our announcements when we're router and are announcing
2711 servers to our primary router. Affected file silcd/server.c.
2713 * Fixed silc_server_command_identify_check_client to assemble
2714 correct WHOIS packet. It send corrupted WHOIS packet and
2715 caused problem with router to router connections. Affected
2716 file silcd/command.c.
2718 Fixed also silc_server_command_whois_check the same way
2719 as for the IDENTIFY command.
2721 * Added new SilcIDListStatus to the server in the SilcIDListData
2722 structure. The status now includes the current status of
2723 the entry (like registered, resolved etc.). Affected file
2724 silcd/idlist.[ch]. Defined a bunch of different status types
2725 as well. This replaced the old boolean registered field as well.
2727 Added resolve_cmd_ident field to the SilcClientEntry structure
2728 too so that if the entry is for example being resolved so
2729 another command may attach to the same pending command reply
2730 without requiring to resolve the same entry again. This concept
2731 should optimize the WHOIS and the IDENTIFY resolving under
2732 heavy load by taking away unnecessary resolving for entries
2733 that are being resolved already.
2735 Added support for adding multiple pending commands for one
2736 command idenfier. Affected file silcd/command[_reply].[ch].
2738 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2739 before deleting the data. Otherwise the hash table will have
2740 freed data in comparison functions. Affected file is
2741 silcd/command_reply.c.
2743 * Fixed silc_idlist_replace_client_id to add the new entry to
2744 the cache with NULL nickname. Otherwise there will be invalid
2745 memory as the nickname after the nickname is freed. Affected
2746 file silcd/packet_receive.c.
2748 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2749 saved into wrong slots because the previous number of entries
2750 was not taken into account. Affected file silcd/idlist.c.
2751 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2753 * If we are router and we receive JOIN notify to a channel that
2754 does not have any users then notified client is marked as the
2755 channel founder, as it is it. The affected file is
2756 silcd/packet_receive.c
2758 * Added to the extended hash table API's table_del_*ext functions
2759 the destructor as argument too, so that the caller can decide
2760 which destructor to use or whether to use destructor at all.
2761 Affected file lib/silcutil/silchashtable.[ch].
2763 * Fixed ID Cache purging. It actually deleted the entries from
2764 the hash table after the data was freed. The hash table ended
2765 up comparing freed memory. The affected file is
2766 lib/silccore/silcidcache.c.
2768 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Fixed Irssi SILC client's KILL command's HELP syntax.
2772 * The USERS command now resolves the detailed user information
2773 if the userinfo field is missing. Affected file is
2774 lib/silcclient/command_reply.c.
2776 * Do not print error in silc_file_read if the read file does
2777 not exist. Just silently return NULL. Affected file is
2778 lib/silcutil/silcutil.c.
2780 * Fixed the silc_log_output to not wine about NULL filename
2781 and to not create some bogus " " filename. Affected file is
2782 lib/silcutil/silclog.c.
2784 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2786 * Fixed various printing bugs on the user interface in the
2787 Irssi SILC Client. Minor changes that were forgotten from
2790 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2792 * Fixed the configure.in.pre and the compilation and distribution
2793 environment to support the new autoconf 2.52. That version is
2794 now required to compile the CVS trunk.
2796 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2798 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2799 to generally parse user@fqdn format strings. Affected file
2800 lib/silcutil/silcutil.c.
2802 * Added nickname_format and nickname_force_format fields to the
2803 SilcClientParams structure. The first one defines the format
2804 for the nicknames that the library will enforce if the receives
2805 multiple same nicknames. The second one is boolean value and
2806 can be used to force the library to always enforce the format
2807 to the nicknames regardles whether there are multiple nicknames
2808 or not. This configurable formatting was employed to flexibly
2809 support accessing multiple nicknames from the user interface.
2810 The userinterface can now set the nicknames to what ever format
2811 they prefer. Affected file lib/silcclient/silcapi.h.
2813 Added function silc_client_nickname_format to the file
2814 lib/silcclient/idlist.c. It performs the nickname formatting.
2816 Added new field `hostname´ to the SilcClientEntry context.
2817 It holds the hostname of the client. Affected file is
2818 lib/silcclient/idlist.h.
2820 * Irssi SILC Client sets the nicknames in nick@hostn format.
2821 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2822 irssi/src/silc/core/silc-core.c.
2824 The WHOIS printing now also shows both the real nickname and
2825 the formatted nickname so that user knows how to access the
2826 user if there are multiple same nicknames cached. Affected
2827 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2828 printing formatting too to take the hostname now as a separate
2829 argument. The Affected file is
2830 irssi/src/fe-common/silc/modules-formats.[ch].
2832 * Changed the silc_client_get_clients_local to accept the formatted
2833 nickname as argument. It accepts the real nickname too but the
2834 formatted nickname can be used to find the true entry from
2835 multiple entries. Affected file lib/silcclient/silcapi.h and
2836 lib/silcclient/idlist.c.
2838 * Added nickname_format_parse field to the SilcClientParams.
2839 It is a callback function provided by the application to parse
2840 the nickname out of the formatted nickname string. The library
2841 calls it to get the nickname from the formatted string. Since
2842 the application generally knows better the format of the nickname
2843 string it parses it instead of the library, even though library
2844 encodes the formatted string. If the callback function is not
2845 provided then the library will use the string as is. The
2846 affected file is lib/silcclient/silcapi.h.
2848 * All the nickname strings passed to the client library in
2849 commands are now expected to be formatted nickname strings.
2850 If the command does not support the formatted nickname string
2851 it will assume that the sent string is the actual nickname.
2852 Affected file lib/silcclient/command.c.
2854 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2856 * Added public key authentication support to OPER and SILCOPER
2857 commands in the client library. Affected file is
2858 lib/silcclient/command.c.
2860 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2862 * Changed the get_auth_methdod client operation to be asynchronous.
2863 It can be async if the application resolves the authentication
2864 method from the server during the negotiation. Added new
2865 SilcGetAuthMeth completion callback that the application will
2866 call after resolving the authentication method.
2868 Added function silc_client_request_authentication_method that
2869 the application can use to resolve the authentication method
2870 from the server. Added also SilcConnectionAuthRequest callback
2871 that the library will call after the server has replied. The
2872 application can call this function if it does not know the
2873 current authentication method.
2875 Affected files are lib/silcclient/client.c and
2876 lib/silcclient/silcapi.h.
2878 * The Irssi SILC client now automatically resolves the authentication
2879 method incase any configuration information is not present (and
2880 currently there never is). The affected file is
2881 irssi/src/silc/core/client_ops.c.
2883 * Fixed public key authentication from the client library.
2884 Affected file lib/silcclient/protocol.c. Changed also the
2885 protocol specification about the public key authentication in
2886 the connection authentication protocol. The actual data to be
2887 signed is now computed with a hash function before signing.
2889 * Fixed the public key authentication from the server as well.
2890 Affected file silcd/protocol.c.
2892 * Removed the mlock()'s from the memory allocation routines.
2893 Affected file lib/silcutil/silcmemory.c. The ./configure does
2894 not check anymore for the mlock(). Affected file is
2897 * Fixed USERS command in server to allow the execution of the
2898 command for private and secret channels if the client sending
2899 the command is on the channel. Affected file silcd/command.c.
2901 * Fixed silc_client_get_clients_local to return the clients
2902 count correctly. It could return wrong value. Affected file
2903 lib/silcclient/idlist.c.
2905 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2907 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2908 types. The assembler optimizations seemed not to like 64-bit
2909 data types. The assmebler optimizations thus are now enabled
2910 also for BSD systems as opposed to only enable them for Linux.
2912 * Do not check for threads at all on BSD systems. Affected
2913 file configure.in.pre.
2915 * Removed -n and -h options from the Irssi SILC Client since
2916 they are not used in silc.
2918 * Fixed the prime generation to assure that the first digit
2919 of the generated random number is not zero since our conversion
2920 routines does not like number strings that starts with zero
2921 digit. If zero digit is seen the random number is regenerated.
2922 This caused some corrupted RSA keys when the zero first digit
2923 was met. Affected file lib/silcmath/silcprimegen.c.
2925 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * Fixed WIN32 configuration in the ./configure script.
2928 Fixed to include xti.h on environments that has it.
2929 Patches by Carsten Ilchmann and andrew.
2931 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Changed the silc_id_create_client_id to be collision
2934 resistant. It is now assured that there cannot be created
2935 two same client ID's. I suspect that some weird bugs in
2936 the server were actually caused by duplicate Client IDs.
2937 Affected file silcd/serverid.[ch]. A router receiving
2938 new ID now also assures and informs the sending server
2939 if the ID caused collision.
2941 * Changed the silc_id_create_channel_id to also assure that
2942 there are no collisions.
2944 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * Statement about ignoring the Mutual Authentication flag when
2947 performing rekey with PFS was a bit misleading. It is ignored
2948 if it was set in the initial negotiation, it cannot be even
2949 set in the rekey. Fixed in the ke-auth draft. Started the
2950 new versions of the protocol drafts in the doc/.
2952 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2954 * Fixed a bug in silc_client_command_identify_save when saving
2955 new channel information. The channel name was no duplicated
2956 and caused crash on exit. Affected file is
2957 lib/silcclient/command_reply.c.
2959 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2961 * Fixed the getkey command handling in the server. Send just
2962 empty OK reply to the sender if the key could not be fetched
2963 (but everything else was ok, like the key just was not available).
2964 Changed the public key parameter to optional in the protocol
2965 specs so that empty OK reply can be sent. Affected file
2968 Added a message to Irssi SILC client to tell to user if the
2969 server did not return a public key.
2971 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * Fixed a channel key regeneration bug. It registered new
2974 timeout tasks exponentially until all system resources were
2975 used. Affected file silcd/server.c.
2977 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2979 * Added the SILC Document generator to the scripts/silcdoc.
2980 It can be used to generate the Toolkit Reference Manual out
2981 of the source tree. Internally it will also use the RoboDoc
2982 generator now imported in util/robodoc.
2984 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2986 * Added couple of return's in rekey protocol if error orccurred
2987 during the protocol. The execution must be terminated.
2988 Affected file silcd/protocol.c. Also, terminate the protocol
2989 always with timeout.
2991 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2993 * The client's Client ID was created initally from the wrong
2994 nickname (it could have been in format nick@host) in the
2995 silc_server_new_client. Affected file silcd/packet_receive.c
2997 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Added some SILC_LOG_ERROR's to various error conditions
3000 if client could not be added to ID cache. Affected files
3001 silcd/packet_receive.c and silcd/server.c.
3003 * When client's sock->user_data is freed, NULL also the
3004 client->router and client->connection pointers. Added check
3005 for these pointers being NULL to various places around the
3006 code. Affected file silcd/server.c.
3008 * Added client->data.registered == TRUE checks to various
3009 places around the code to assure that unregistered client's
3010 are not handled when it is not allowed. Affected file
3013 * Added `bool registered' fields to all
3014 silc_idlist_[server|client]_get_* routines to indicate whether
3015 the fetched client needs to be registered or not. Affected
3016 file silcd/idlist.[ch].
3018 * Add your own entry as registered to the ID cache in the
3019 server. Affected file server.c.
3021 * Fixed a bug in silc_server_new_server. The SilcServer was
3022 set as the new server's context instead of SilcServerEntry.
3023 This naturally caused some weird bugs.
3025 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Do not delete the channel rekey task when adding it
3028 for in silc_server_create_channel_key.
3030 * Changed the silc_server_create_channel_key to return
3031 TRUE or FALSE to indicate the success of the channel key
3034 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * Fixed MSVC++ project files and added missing files to
3037 Makefiles under win32/.
3039 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3041 * Do not add TCP_NODELAY flag if the operating system
3042 does not have it defined. Affected files are
3043 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3045 * Fixed buffer overflow from Irssi SILC Client. Affected
3046 file irssi/src/fe-common/core/themes.c.
3048 * Fixed double free in client library in the file
3049 lib/silcclient/client.c when disconnecting from server.
3051 * Applied double free patch from cras to Irssi SILC client.
3052 Affected files irssi/src/core/[modules/expandos].c
3054 * Fixed the disconnection handling to Irssi SILC Client.
3055 The application must call silc_client_close_connection
3056 in ops->connect client operation in case of failure of
3057 the connection. Affected file is
3058 irssi/src/silc/core/client_ops.c.
3060 * Do not set sock->protocol to NULL in the function
3061 silc_client_close_connection after executing the protocol's
3062 final callback since the sock might not be valid anymore.
3063 Affected file lib/silcclient/client.c.
3065 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3067 * Do not enable SILC_THREADS if the linking with libpthread
3068 did not happen. Affected file configure.in.pre.
3070 * Added notion to protocol specification that server must
3071 verify the sent authentication payload with CMODE when
3072 setting the channel founder key. Implemented it to the
3073 server. Affected file silcd/command.c.
3075 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3077 * Added _EXTRA_DIST SILC distribution variable to the
3078 distributions file. It is used to conditionally add extra
3079 files or directories to the specific distribution. Affected
3080 files ./prepare, Makefile.am.pre and distributions.
3082 Removed the `_' from the start of the distribution names.
3085 * Added README.WIN32 for instructions to compile the Toolkit
3088 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3090 * Fixed a double free in disconnection in the server. Affected
3091 file is silcd/server.c.
3093 * Fixed the lib/silcske/groups.c to work now also with GMP
3094 MP library. The string conversion did not work when using
3095 specific base and the base is indicated in the string as well.
3097 * Created win32/ directory which now includes MSVC++ specific
3098 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3099 It will appear only in the toolkit distribution
3101 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3103 * Changed the key material distribution function in case when
3104 the hash output is too short. The data is now concatenated
3105 a bit differently than it used to. Made the change to the
3106 SKE protocol specification.
3108 * Added better GMP detection to configure.in.pre. A patch
3111 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * Fixed a minor bug in SKE that might cause some problem on
3114 some platforms. Affected file lib/silcske/silcske.c.
3116 * Added the cookie checking for initiator in the SKE. It checks
3117 that the responder returns the sent cookie unmodified. The
3118 affected file is lib/silcske/silcske.c. Added new SKE
3119 error type INVALID_COOKIE that can be sent during the
3120 negotiation. Fixed some memory leaks as well.
3122 * Added the "invalid cookie" error message to Irssi SILC client's
3125 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3127 * Added `task_max' field to the SilcClientParams to indicate
3128 the maximum tasks the scheduler can handle. If set to zero,
3129 default values are used. Affected file lib/silcclient/silcapi.h.
3131 * Fixed memory leaks in silc_client_close_connection. Affected
3132 file lib/silcclient/client.c.
3134 * Added silc_client_del_client_entry to client library to free
3135 all memory of given client entry. Affected file is
3136 lib/silcclient/idlist.[ch].
3138 * Added new functions silc_client_del_channel and
3139 silc_client_del_server to delete channel and server entries.
3140 Affected file lib/silcclient/[silcapi.h/idlist.c].
3142 * Removed silc_client_del_client_by_id from silcapi.h.
3144 * Fixed the INFO command to return the server's own info
3145 correctly when querying by Server ID. Affected file is
3148 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3150 * Removed the non-blocking settings in WIN32 code in the
3151 silc_sock_[read/write] and added SleepEx instead. Affected
3152 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3153 of input data is now checked with FIONREAD and ioctlsocket.
3155 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3157 * Call silc_schedule_task_del_by_context in the
3158 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3159 Affected file lib/silccore/silcprotocol.c.
3161 * Call silc_protocol_cancel for active protocols in the
3162 silc_server_close_connection if the funtion
3163 silc_server_free_sock_user_data has not been called.
3164 Affected file silcd/server.c.
3166 * Generic tasks cannot be deleted using the del_by_fd
3167 task deleting function since generic tasks does not match
3168 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3170 * Added a notion to SILCOPER help file that the SILCOPER works
3171 only on router server, not on normal server.
3173 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3175 * Added for WIN32 support for the new scheduler as well.
3176 Affected file lib/silcutil/win32/silcwin32schedule.c.
3178 * Fixed the SHA1 implementation to work on various platforms.
3180 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3182 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3183 API. It is part of the scheduler now. Everything else is
3184 as previously but some functions has changed their names.
3185 Checkout the lib/silcutil/silcschedule.h for the interface.
3186 Updated all applications to use the new interface. Affected
3187 files are lib/silcutil/silcschedule.[ch].
3189 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3191 * Found a bug in the SKE implementation. The HASH value,
3192 specified by the protocol, was not computed correctly. The
3193 public key of the responder was not added to the computation
3194 even though it is mandatory. Affected file lib/silcske/silcske.c.
3195 This unfortunately causes incompatibilities with older
3196 clients and servers.
3198 * Added WIN32 specific network init and uninit functions:
3199 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3200 the Winsock2. Affected file lib/silcutil/silcnet.h and
3201 lib/silcutil/win32/silcwin32net.c.
3203 * Set the socket always to nonblocking mode on WIN32 after
3204 reading data or writing data. Affected file is
3205 lib/silcutil/win32/silcwin32sockconn.c.
3207 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3209 * Fixed various compilation problems under WIN32. Affected
3210 files lib/silcutil/win32/silcwin32thread.c and
3211 lib/silcutil/win32/silcwin32schedule.c.
3213 * Removed all _internal.h #includes from public header
3214 files. Internal headers must never be included from
3217 Removed also the lib/silcske/payload_internal.h file.
3219 * All include files that may be needed (public and some others
3220 included by the public headers) by application developers are
3221 now copied to the ./includes directory. It does not copy any
3222 internal headers. Affected file Makefile.defines.pre and all
3223 Makefile.am's under lib/ and subdirs.
3225 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3227 * Do not change the ~/.silc directory's permissions automatically.
3228 Affected file irssi/src/silc/core/clientutil.c.
3230 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3232 * Do not cancel the protocol in silc_server_close_connection
3233 it might cause recursion. Now cancelled in the function
3234 silc_server_free_sock_user_data. Affected file silcd/server.c.
3236 * Fixed the silc_server_remove_clients_by_server to regenerate
3237 the channel keys correctly finally. Added also new function
3238 silc_server_remove_clients_channels to actually do it.
3239 Affected file silcd/server.c.
3241 * Fixed the silc_server_new_channel to not crash by giving
3242 wrong router to the new channel. Affected file is
3243 silcd/packet_receive.c.
3245 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3247 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3248 which is given as argument to the silc_client_alloc now.
3249 It can be used to configure the client and set various parameters
3250 that affect the function of the client.
3252 * The USERS command in server did not check whether the channel
3253 is private or secret. Affected file silcd/command.c.
3255 * Added new argument to the USERS command in protocol specification.
3256 The USERS command now can take the channel name as argument
3257 as well. Added support for this in client and server and
3258 updated the protocol specs.
3260 * Completed the GETKEY command in client. It can be now used
3261 to fetch also servers public key not only some clients.
3262 Affected files lib/silcclient/command[_reply].c.
3264 * Added silc_client_get_server to return server entry by the
3265 server name. Affected files lib/silcclient/silcapi.h and
3268 * Redefined the IDENTIFY command in protocol specification to be
3269 more generic. It now can be used to query information about
3270 any entity in the SILC Network, including clients, servers and
3271 channels. The query may be based either the entity's name
3272 or the ID. Added support for this in both client and server.
3274 Affected files silcd/command.c and lib/silcclient/command.c
3275 and command_reply.c.
3277 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3278 the _from_client and _from_server functions. Affected file
3281 * Added silc_client_get_channel_by_id_resolve to the file
3282 lib/silcclient/silcapi.h to resolve channel information by
3283 its ID. Added also silc_client_get_channel_by_id that
3284 does not resolve it from the server.
3286 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3288 * Added SilcServerEntry context into the client library
3289 to represent one server. The INFO command now allocates
3290 these to save the resolved server info. For now on the
3291 client library will also keep information about servers,
3292 connected and resolved with INFO.
3294 The INFO command now allocates the SilcServerEntry context
3295 and saves the server info there. The COMMAND_REPLY in
3296 the INFO now returns the parameters to application in
3297 same order as defined in the protocol specification.
3299 The entries are cached in the client->server_cache.
3301 * The INFO command is now issued after received the Client ID
3302 from the server. Affected file lib/silcclient/client.c.
3304 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3305 to the application as the mode changer might be server.
3306 It is guaranteed that NULL is not returned anymore to the
3307 application. Affected file lib/silcclient/client_notify.c.
3309 The ID Type is now also passed to the application so that
3310 it can check whether the returned entry is SilcClientEntry
3313 Added new function silc_client_get_server_by_id to return
3314 the server entry by ID. Affected files are the
3315 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3317 * Do not create the channel in the Irssi SILC Client when issuing
3318 the JOIN command but when received the sucessful JOIN command
3319 reply. Otherwise the channel might get created even though we
3320 could not join it. The Affected file is
3321 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3323 * Fixed a channel joining bug in router. The router must also
3324 check the channel modes, invite and ban lists etc. when serving
3325 the JOIN command sent by normal server. Affected file is
3326 silcd/command.c. The router now resolves the client's
3327 information from the server who sent the JOIN command if it
3328 does not know it, and processes the JOIN command only after
3331 * Changed the SilcCommandCb to take new argument; void *context2.
3332 Affected file lib/silccore/silccommand.h
3334 The second argument in the command callbacks in the server now
3335 includes the SilcServerCommandReplyContext if the command was
3336 called as pending command callback from the command reply.
3337 Otherwise it is NULL. When called as pending the status of the
3338 command reply will be checked and if it was erronous the
3339 error will be sent to the original sender of the command.
3340 This way the client always receives the error messages even
3341 though the server was actually the one who received the error
3342 when it resent the command to router, for example. Affected
3343 files silcd/command[_reply].[ch].
3345 * Fixed sending WHOWAS command's error message to client if
3346 the requested client could not be found. It was missing.
3349 * Changed the CMODE and CUMODE commands reply arguments in the
3350 protocol specification. The Channel ID is now sent in both
3351 of the commands to identify the channel. Implemented this
3352 new feature to the client and server. Affected files
3353 lib/silcclient/command_reply.c and silcd/command.c.
3355 * Made better checks for invite and ban lists in the JOIN
3356 command in server. Affected file silcd/command.c.
3358 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3360 * The server now performs the incoming host IP/DNS lookup
3361 using the silc_socket_host_lookup and thus does not block
3362 the server anymore. Affected file silcd/server.c.
3364 * Completed the multi-thread support for SILC Scheduler in
3365 the lib/silcutil/silcschedule.c.
3367 * Fixed the configure.in.pre to detect the pthread correctly
3370 * Fixed a deadlock in silc_task_queue_wakeup in the file
3371 lib/silcutil/silctask.c.
3373 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Added new function silc_schedule_wakeup that is used in
3376 multi-threaded environment to wakeup the main thread's
3377 schduler. It needs to be used when a thread adds a new task
3378 or removes a task from task queues. After waking up, the
3379 scheduler will detect the task queue changes. If threads
3380 support is not compiled in this function has no effect.
3381 Implemented the wakeup mechanism to both Unix and WIN32
3382 systems. Affected files are lib/silcutil/silcschedule.[ch],
3383 lib/silcutil/unix/silcunixschedule.c and the
3384 lib/silcutil/win32/silcwin32schedule.c.
3386 * Added new function silc_task_queue_wakeup to wakeup the
3387 scheduler by the specified task queue. Affected file
3388 lib/silcutil/silctask.[ch].
3390 * The silc_socket_host_lookup_start now wakes up the scheduler
3391 after adding the timeout task. Affected file is
3392 lib/silcutil/silcsockconn.c.
3394 * The silc_socket_host_lookup is synchronous now if the threads
3395 support is not compiled in. However, the callback is still
3396 called asyncronously through the scheduler, anyway. Affected
3397 file lib/silcutil/silcsockconn.c.
3399 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3401 * Added new function silc_socket_host_lookup to perform
3402 asynchronous IP and FQDN lookups for the socket connection.
3403 Affected files lib/silcutil/silcsockconn.[ch].
3405 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3407 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3408 that may or may not compile the mutex support in.
3410 Changed the silc_mutex_alloc interface. It allocates the
3411 mutex now to the sent pointer and returns TRUE or FALSE.
3413 Affected file lib/silcutil/silcmutex.h.
3415 * Wrote the SILC Task Queue interface to support multi-threads.
3416 Affected file lib/silcutil/silctask.[ch].
3418 * Wrote the SILC Scheduler to support multi-threads. Affected
3419 file lib/silcutil/silcschedule.c.
3421 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3423 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3424 in lib/silcutil/win32/.
3426 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3428 * Defined SILC Mutex API and SILC Thread API and implemented
3429 them for Unix. Affected files are
3430 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3431 lib/silcutil/unix/silcunixmutex.c and
3432 lib/silcutil/unix/silcunixthread.c.
3434 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3436 * Fixed the silc_server_remove_clients_by_server's channel
3437 key re-generation. The hash table handling was incorrect
3438 and would not work with many channels. Affected file is
3441 * Fixed some memory leaks around the server code.
3443 * Rewrote the silc_server_get_users_on_channel to support IPv6
3444 based Client ID's. Affected file silcd/server.c.
3446 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3447 specification. However, a separate document must be written
3448 to define the detailed signing procedure and the payload
3449 associated with the flag. Defined the flag to the
3450 lib/silccore/silcchannel.h as well.
3452 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3454 * Changed the dynamic tables to static size tables in the
3455 lib/silccrypt/silchmac.c.
3457 * Removed GCC dependencies from the code. A patch by cras.
3459 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3461 * Do not show the error "Error receiving packet bla bla"
3462 in server if it really was not an error (-2 means that reading
3463 is pending). Affected file silcd/server.c.
3465 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3467 * Fixed a possible crash in silc_server_remove_clients_by_server
3468 in silcd/server.c. Fixed there also some memory leaks.
3470 * Fixed the silc_idlist_replace_client_id. It could replace
3471 wrong key in the hash table. Affected file silcd/idlist.c.
3473 * Do not check whether there are global users on the channel
3474 if the channel->global_users is FALSE. Affected functions
3475 silc_server_remove_from_one_channel and
3476 silc_server_remove_from_channels in silcd/server.c. Also,
3477 do not check if the removed client is local as we can be
3478 sure that global client was not removed from the channel
3479 and checking for global users is not needed.
3481 * The silc_server_remove_clients_by_server now re-generates
3482 the channel keys correctly for those channels that had
3483 clients removed from them. Affected file silcd/server.c.
3485 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Found the reason of random crashes in the server. We weren't
3488 ignoring the SIGPIPE signal (which can be sent in write())
3489 and it crashed the server. Affected file silcd/silcd.c.
3491 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3493 * Assure that sock->user_data is not NULL in the function
3494 silc_server_packet_send in silcd/packet_send.c.
3496 * Disconnect the remote connection if it could not be added
3497 to any ID lists in the server. The affected file is
3500 * Check in silc_server_packet_send[_real/dest] that the
3501 socket is not disconnecting and ignore the data if it is.
3502 Affected file silcd/packet_send.c.
3504 * Define inline to __inline on native WIN32 compilation.
3505 Affected file includes/silcwin32.h.
3507 * Added some explicit type casts for inline code since MSVC
3508 require them. Affected files lib/silcutil/silcbuffer.h,
3509 lib/trq/silcdlist.h and lib/trq/silclist.h.
3511 * Print warning in log files from now on if the packet
3512 decryption fails. Affected file silcd/server.c.
3514 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3516 * Changed the `say' client operation's interface to accept
3517 new `type' argument to indicate the type of the message sent
3518 by the library. The application may filter the library's
3519 messages according the type. The affected file is the
3520 lib/silcclient/silcapi.h.
3522 * Added two new functions to lib/silcclient/silcapi.h:
3523 silc_client_del_client and silc_client_del_client_by_id.
3524 Affected file lib/silcclient/idlist.c.
3526 * Moved the clientincludes.h from includes/ to silc/ and
3527 serverincludes.h from includes/ to silcd/.
3529 * The modes for the CMODE and CUMODE are now passed as
3530 uint32 for application with COMMAND_REPLY. The affected
3531 file is lib/silcclient/command_reply.c.
3533 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3535 * /WHOIS without arguments shows client's own information.
3536 Affected file lib/silcclient/command.c.
3538 * Changed PING to not accept any arguments. The specs
3539 says that client can ping only the connected server so
3540 requiring an argument is not needed. Affected file is
3541 lib/silcclient/command.c.
3543 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3545 * Fixed a fatal bug in private message sending and reception
3546 encryption and decryption when using private message keys.
3547 The implementation was incorrect and did not follow the
3548 specification. It causd that some of the message were
3549 lost since it did not use the sending and receiving keys
3550 as the protocol suggests. This has been fixed and will cause
3551 incompatibilities with older clients when sending private
3552 message encrypted with private message keys. Affected files
3553 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3554 and various other in Irssi SILC Client.
3556 Added `responder' boolean argument to the functions
3557 silc_client_add_private_message_key[_ske] to indicate when
3558 the key is added as responder or initiator of the key
3561 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3563 * Removed the silc_ske_check_version function and created
3564 a SilcSKECheckVersion callback. Added also a function
3565 silc_ske_set_callbacks that is now used to set all SKE
3566 callbacks. The callback functions are not given to
3567 the SKE functions anymore, but this function is used to
3570 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3572 * Added `silc_version' argument to the silc_client_alloc
3573 to define the version of the application for the library.
3574 The library will use the version string to compare it
3575 against the remote host's (usually a server) version
3576 string. Affected file lib/silcclient/silcapi.h
3578 * Added the KE protocol context to Key Agreement context
3579 in client library so that we can abort the SKE if it
3580 is in process when we get timeout. Affected file is
3581 lib/silcclient/client_keyagr.c.
3583 * Do not resolve the client ID forever if it returns in the
3584 first time that such client does not exist. This was done
3585 for example with private message. Affected file is
3586 lib/silcclient/client_prvmsg.c.
3588 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3590 * Do not add regex.h for WIN32. The affected file
3591 includes/silcincludes.h.
3593 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3594 not work yet 100%. It generates the DLL's automatically
3595 when compiling with --with-win32 under cygwin.
3597 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3599 * lib/contrib/regex.c is not compiled on WIN32.
3601 * Added silc_net_get_socket_opt function to the
3602 lib/silcutil/silcnet.h.
3604 * Added includes/silcwin32.h for WIN32 specific includes
3607 * Do not use ptime structure or any of the posix process
3608 functions on WIN32 in lib/silccrypt/silrng.c.
3610 * Added silc_gettimeofday to provide generic function
3611 for struct timeval on all platforms. Added the function
3612 to lib/silcutil/silcutil.h.
3614 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3616 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3617 library as they clearly belong there. As a plus side we
3618 can make the actual socket connection routines platform
3621 Added also new generic function silc_socket_read and
3622 silc_socket_write (that used to be silc_packet_[read/write].
3623 The implementation of these are platform specific.
3625 * Added WIN32 specific routines of silc_socket_[read/write]
3626 to lib/silcutil/win32/silcwin32sockconn.c.
3628 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3630 * Added preliminary support for native WIN32 compilation under
3631 cygwin (using the -mno-cygwin option for GCC) to the
3632 ./configure.in.pre. The --with-win32 now prepares the
3633 compilation for native WIN32.
3635 * Rewrote the SILC Scheduler interface in the file
3636 lib/silcutil/silcschedule.h. The scheduler is now context
3637 based and does not have anymore any global static scheduler.
3638 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3639 and created lib/silcutil/win32 directory for WIN32 based
3642 * Added Unix specific network routines to the
3643 lib/silcutil/unix/silcunixnet.c and the old
3644 lib/silcutil/silcnet.c includes now only generic routines.
3646 Added WIN32 specific network routines to the
3647 lib/silcutil/win32/silcwin32net.c.
3649 * Added Unix specific utility functions from the
3650 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3652 * Added WIN32 SILC Scheduler to the file
3653 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3656 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3658 * Do not handle JOIN notify in the server if the target client
3659 is not registered (idata->registered == FALSE). The affected
3660 file is silcd/packet_receive.c.
3662 * Update the nickrec->founder in event_cumode in the Irssi SILC
3663 client. Affected file irssi/src/silc/core/silc-channels.c.
3665 * Fixed the CUMODE_CHANGE notify handling in the server when
3666 server and router are announcing their clients on channels.
3667 Now the mode changes are saved and notified correctly. The
3668 affected file is /silcd/packet_receive.c.
3670 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3671 They really did not replace the cache entry in the ID Cache.
3672 Now they do that. Affected file silcd/idlist.c.
3674 * Fixed the KICK notify handling in the Irssi SILC client to
3675 update the channel records so that the kicked client does not
3676 appear to be on the channel. The affected file is
3677 irssi/src/silc/core/silc-channels.c.
3679 * Always update the conn->current_channel when executing command
3680 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3682 * Fixed the KILL notify handling in Irssi SILC client to remove
3683 the killed client on all channels.
3685 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3687 * Fixed the silc_parse_command_line to remove extra spaces
3688 from the start and end of the arguments. Affected file is
3689 lib/silcutil/silcutil.c.
3691 * Cancel and free any active protocol in the function
3692 silc_server_close_connection. Affected file silcd/server.c.
3694 * Cancel and free any active protocol in the function
3695 silc_client_close_connction. Affected file is
3696 lib/silcclient/client.c.
3698 * Do not execute the KILL command for clients that are in
3699 history (ie. they are not in the network). Affected file is
3702 * Fixed KILL notify handling, client does not crash anymore.
3703 Affected file irssi/src/silc/core/silc-channels.c.
3705 * Reduced the default packet buffer size from 2048 to 1024 in
3706 lib/silccore/silcpacket.c.
3708 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3709 counter to the SKE context that is incresed when the SKE library
3710 performs async operation outside the library. If the outside
3711 process frees the SKE context and FREED status will be set
3712 and the library will detect after the sync operation that the
3713 libary is freed. The affected files are
3714 lib/silcske/silcske[_status].[ch].
3716 * Resolve the client entry information in the function
3717 silc_client_channel_message to assure that NULL pointer is not
3718 passed as client entry to the application. */
3720 * Fixed the task timeout calculation to assure that there is
3721 never negative timeouts. The affected file is
3722 lib/silcutil/silcschedule.c.
3724 * Fixed the channel user mode notification sending in server.
3725 It was sent point-to-point to the router (or to server by router)
3726 but it needs to be destined to a channel. The routines now
3727 supports sending the channel user mode notifys to the channels
3728 when announcing clients and channels. Affected files are
3729 silcd/server.c and silcd/packet_receive.c.
3731 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3732 It did not actually replace the old channel entry in the cache.
3733 Affected file lib/silcclient/client_notify.c.
3735 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3737 * Fixed a possible crash in silc_packet_send_prepare. It now
3738 assures always that there is enough space in the buffer and
3739 at the tail area of the buffer (for MAC).
3741 Fixed the inbound buffer reallocation in silc_packet_read.
3742 It was old code and did not handle the reallocation correctly.
3745 The affected file is lib/silccore/silcpacket.c.
3747 * Fixed buffer overflow in silc_parse_nickname in the file
3748 lib/silcutil/silcutil.c.
3750 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * make install generates new server keys only if there is not
3755 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3758 Added check that if the NOREPLY is set then we will not send
3759 the away message. This avoids infinite loop of away messages
3760 if both clients are away. The affected file is
3761 lib/silcclient/client_prvmsg.c.
3763 * Fixed client crash if /NICK was given without arguments.
3764 Affected file lib/silcclient/command.c.
3766 * Server does not send the invite list in INVITE command back
3767 to the client if the list was not altered. Added this notion
3768 to the protocol spec as well. Affected file silcd/command.c.
3770 Fixed possible crash in INVITE command by checking the
3771 value of silc_server_get_client_route command.
3773 * Fixed the INVITE notify type handling. The arguments are now
3774 taken in correct order and client does not crash. The affected
3775 file is irssi/src/silc/core/silc-channels.c.
3777 Removed the "Inviting xxx to channel" message from the
3778 client library away and let the application handle it.
3779 Affected file lib/silcclient/command.c. Added that message
3780 to Irssi SILC client's message formats.
3782 * Fixed CMODE command crash in client. It now checks the
3783 amount of arguments correctly and does not crash. The affected
3784 file is lib/silcclient/command.c.
3786 * Do not create new channel automatically in silc_channels_join
3787 but check whether the channel by that name already exists.
3788 Affected file irssi/silc/core/silc-channels.c.
3790 * Do not send the SERVER_SIGNOFF to router if the disconnected
3791 entity was the router. Affected file silcd/server.c.
3793 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3794 SILC client as it was missing from there.
3796 Added the handling of the KICK notify to the Irssi SILC client
3797 as it was missing. Added "you have been kicked" message to
3798 Irssi SILC client's message modules formats.
3800 Added the handing of the KILL notify to the Irssi SILC client
3801 as it was missing. Added the kill message module formats
3804 The affected file is irssi/src/silc/core/silc-channels.c.
3806 * The router did not save the channel mode the server announced.
3807 Affected file silcd/packet_receive.c.
3809 * Fixed a possible crash in INFO command in server. If the
3810 server did not provide the server info it crashed. Affected
3811 file silcd/command.c.
3813 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Fixed the GETKEY command in the server to check also the
3816 global list. Otherwise the GETKEY would not work correctly
3817 in normal SILC server. Affected file silcd/command.c.
3819 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Fixed GETKEY crash, it crashed if the command did not succseed.
3823 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3826 is now real and not just an macro interface to GMP.
3828 Removed the entire GMP from the source tree and imported new
3829 NSS MPI library instead. Reason for removing GMP is that it is
3830 extremely large and compiles extremely slow. The NSS MPI
3831 is only a few files and compiles in less than 10 seconds.
3832 The speed is also about the same as GMP. The MPI is imported
3833 to lib/silcmath/mpi.
3835 If the system has GMP installed we will still use the GMP.
3836 If it is not then the NSS MPI will be compiled.
3838 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3840 * Merged a long nickname (127 characters long) crash bugfix from
3841 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3843 * Merged a freed memory reference bugfix from Irssi CVS tree.
3844 Affected file irssi/src/core/commands.c.
3846 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3848 * Added the server's public key sving and verification to the
3849 server when performing the SKE. This was missing and the
3850 remote server's (or router's) public key was accepted without
3851 checking whether we have it previously or trust it at all.
3852 Affected file silcd/protocol.c.
3854 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Check in the silc_server_timeout_remote if protocol is active
3857 and make sure that the protocol's final callback is called so
3858 that all memory if freed. Affected file silcd/server.c.
3860 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * silc_server_whois_send_reply crashed the server if the nickname
3863 was 127 characters long. Affected file silcd/command.c.
3865 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Added sanity check to the silc_server_new_client. If the hostname
3868 is provided inside username then check that the provided hostname
3869 really is the same as the resolved one. If the hostname was not
3870 resolved then check it from the public key. Affected file is
3871 silcd/packet_receive.c.
3873 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3874 if the server disconnected us and the connection is not valid
3875 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3877 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3878 the library to the lib/silcutil/silcutil.[ch].
3880 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Close log file after open. Affected file
3883 lib/silcutil/silclog.c.
3885 * Check whether sock == NULL in silc_client_send_packet and return
3886 if it is. Affected file lib/silcclient/silcclient.c.
3888 * Check rec->entry == NULL in the Irssi SILC Client before
3889 sending the channel message. Affecte file is
3890 irssi/src/silc/core/silc-servers.c.
3892 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3894 * Merged a splitted window bugfix from Irssi CVS tree. The
3895 affected file is irssi/src/fe-text/textbuffer-view.c.
3897 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3898 It did not print nickname.
3900 * Improved the distributions system a bit.
3902 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3904 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3905 irssi/src/fe-text/gui-window.c.
3907 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3908 to in-active server. The affected file is
3909 irssi/src/silc/core/client_ops.c.
3911 * Resolve the client in USERS command reply if the entry does
3912 not have username resolved. The affected file is
3913 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3914 command to WHOIS command to really resolve stuff. The USERS
3915 is not used any more in any critical section so WHOIS can
3916 be used even though it might be slower than IDENTIFY.
3918 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3921 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3923 * Changed the protocol API a bit more consistent in the
3924 lib/silccore/silcprotocol.[ch].
3926 * Changed the following headers to ROBODoc format:
3928 lib/silccore/silcpayload.h
3929 lib/silccore/silcprotocol.h
3930 lib/silccore/silcsockconn.h
3932 All core library headers are now formatted.
3934 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3936 * Fixed a bug in Irssi SILC client; do not show that you are
3937 server/router operator if you really are not. Affected file is
3938 irssi/src/silc/core/client_ops.c.
3940 * Renamed silc_command_free_payload to silc_command_payload_free.
3941 Affected file lib/silccore/silccommand.h
3943 * Added silcmath.h to include the prototoypes of various routines
3944 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3947 * Changed the following headers to ROBODoc format:
3949 lib/silccore/silcchannel.h
3950 lib/silccore/silccommand.h
3951 lib/silccore/silcid.h
3952 lib/silccore/silcidcache.h
3953 lib/silccore/silcmode.h
3954 lib/silccore/silcnotify.h
3955 lib/silccore/silcpacket.h
3956 lib/silcmath/silcmath.h
3958 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Added checking to the server code not to start the server if
3961 ciphers and stuff are not configured properly. Affected files
3962 silcd/serverconfig.[h] and silcd/server.c.
3964 * Changed the layout of the header files of the public interfaces
3965 in the SILC libraries. The new layout supports ROBODoc
3966 documentation tool (and some others) so that it is easy to create
3967 a library reference manual. All the other headers and source
3968 code must still follow the CodingStyle document. Also source
3969 code must not include these ROBODoc stuffs, only the headers.
3970 Furthermore, all public interface headers must now be named
3971 by using `silc' prefix, example: silcapi.h, silccipher.h.
3972 Some files were renamed due to this. All the other headers
3973 must not be used as public interfaces. I will update the
3974 CodingStyle document later. Changed following headers, so far:
3976 lib/silcclient/silcapi.h
3977 lib/silccore/silcauth.h
3978 lib/silccore/silcprivate.h
3979 lib/silccrypt/silcdh.h
3981 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Removed silc_client_packet_send_flush from the client library
3986 as it is not needed. Affected file lib/silcclient/client.[ch].
3988 * Added printing of message of unresolved authentication method
3989 to the Irssi SILC client. Added it to the module formats.
3990 Removed the same message from the client library.
3992 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Added new distribution feature, DISTLABEL. Every distribution
3995 can define own preprocessor label that can be used in the
3996 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3997 file distributions, acconfig.h.pre and prepare.
3999 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Added Makefile.defines_int to include the actual definitions
4002 for Makefile.defines.in. Tested the new distribution system,
4003 created distributions and tested installation.
4005 * Added AWAY message printing to the Irssi SILC client. Added
4006 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4008 * Added SCONNECT command to call the SILC's CONNECT command.
4009 Cannot use CONNECT directly since Irssi uses that internally.
4010 Affected file irssi/src/silc/core/silc-servers.c.
4012 Added ACTION local command. It is same as ME command but takes
4013 the channel as mandatory argument.
4015 Rewrote some of the Irssi's help files to suite for SILC
4018 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Added Makefile.defines[.in] that should for now on be included
4021 in all Makefile.am file in the source tree. That file includes
4022 all common compilation definitions for SILC source tree.
4024 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Minor changes to the ./prepare script to change the package
4027 name according the distribution name to the configure.in.
4029 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * Created new distribution system. Added file `distributions'
4032 that defines all the distributions that can be created out of
4033 the SILC source tree. The ./prepare script now reads that
4034 file to determine how to prepare the distributions. The
4035 first argument to the ./prepare is the name of the distribution
4036 and second is the version of the distribution. If given
4037 without arguments it creates the default (toolkit) distribution
4038 with the default version (defined in ./prepare).
4040 All Makefile.am files that are subject to the distributions
4041 are now named as Makefile.am.pre. These are ./Makefile.am
4042 and lib/Makefile.am. Others may be changed later.
4044 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Added invite list, ban list, some key management and connection
4047 error message printing to module formats in the Irssi SILC client.
4049 * Added new silc_client_set_away_message to set the away message
4050 that is back to the person who sent private message. The
4051 affected file lib/silcclient/silcapi.h and the
4052 lib/silcclient/client_prvmsg.c.
4054 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Fixed the private message sending in the Irssi SILC client,
4057 added local command KEY to the Irssi SILC client.
4059 Added key management and key agreement message formats to the
4060 irssi/src/fe-common/silc/module-formats.[ch].
4062 Added USERS (alias WHO) printing, server/router operator
4063 indication and LIST command printing to the module formats.
4065 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4067 * Fixed channel joining notify handling, cumode notify handling
4068 from Irssi SILC client.
4070 * Added SILC specific module-formats to the Irssi SILC client so
4071 that SILC specific message hilighting, colors etc is possible.
4072 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4074 Added channel mode, channel user mode, actions, notices,
4075 whois and whowas printing to the the module-formats.c.
4077 * Fixed a bug in channel deletion in the server. The channel
4078 is not left to the cache even if the channel founder auth mode
4079 is set when there are no users anymore on the channel. Affected
4080 file silcd/server.c.
4082 * The silc_net_localhost now resolves the entire hostname including
4083 the domain name. Affected file lib/silcutil/silcnet.c.
4085 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4087 * Changed the ask_passphrase client operation to be ascynchronous.
4088 It has now a completion callback and a context that the
4089 application must call after it has got the passphrase from
4090 the user. Affected files lib/silcclient/silcapi.h,
4091 lib/silcclient/protocol.c, lib/silcclient/command.c and
4094 Added SilcAskPassphrase callback that the application calls
4095 to deliver the passphrase to the library.
4097 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4098 The public key verification and especially a certificate
4099 verification is asynchronous procedure.
4101 Added new SILC_SKE_STATUS_PENDING status to indicate the
4102 request is pending and a callback will be called to finalize
4105 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4106 indicate that remote end did not send its public key (or
4107 certificate), even though we require it. Added check for this
4108 condition in the SKE. This was a security bug, now fixed.
4110 Defined new SilcSKEVerifyCbCompletion callback that is called
4111 when the verification process is completed.
4113 The affected files lib/silcske/silcske_status.h and
4114 lib/silcske/silcske.[ch].
4116 * Changed the verify_public_key client operation to be async
4117 as well. Defined SilcVerifyPublicKey callback that is used to
4118 indicate the success of the public key verification process.
4120 Changed the server and client to use the new async client
4123 * Changed the Irssi SILC client's internal scheduler to be called
4124 twice as many times as it used to be. As a result the client
4125 should be a bit faster now. Affected file is
4126 irssi/src/silc/core/silc-core.c.
4128 * Added support to Irssi SILC client of asynchronous public key
4129 verification and passphrase inquiry. Affected file is
4130 irssi/src/silc/core/silc-core.c.
4132 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4134 * Do not say "You have left channel %s" in client library.
4135 Moved it to the application. Affected files are
4136 lib/silcclient/command.c and silc/client_ops.c.
4138 * Fixed silc_client_get_clients. Command context was not
4139 duplicated and was freed memory in the callback. Affected
4140 file lib/silcclient/idlist.c.
4142 * Do not say "you are now talking..." on JOIN command in the
4143 client library. The appliation must handle it.
4145 * Do not say ".. changed topic to" in command reply in the
4146 client libary. The application must handle it.
4148 * Fixed TOPIC command sending in the client library.
4150 * Fixed a memory leak in silc_client_command_free in the file
4151 lib/silcclient/command.c.
4153 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Imported a modified version of Irssi client to the source tree.
4156 The Irssi will be used to create a new client called
4157 Irssi SILC. Imported to irssi/.
4159 Added silc_core_init_finish function to the Irssi. Affected
4160 file irssi/configure.in.
4162 A lot changes in the Makefile.ams around the irssi tree.
4164 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Do not rehash if the new size is same as the old size of the
4167 hash table, in the silc_hash_table_rehash*. The affected file
4168 lib/silcutil/silchashtable.c.
4170 * Replaced hash_table_del_by_context calls from the server
4171 (when channel->user_list and client->channels) to the
4172 hash_table_del as it is sufficient and faster.
4174 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Added silc_hash_table_list, silc_hash_table_get and the
4177 SilcHashTableList structure to provide an alternative way to
4178 traverse the hash table. The affected files are
4179 lib/silcutil/silchashtable.[ch].
4181 * Changed the server's idlist routines to use the hash table
4182 routines to optimize the code.
4184 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Replaced the client entry's `channel' list and channel entry's
4187 `user_list' list to hash tables for optimized lookup. Changed
4188 the code to use the hash table interface around the code.
4189 Affected file lib/silcd/idlist.[ch].
4191 * Added `auto_rehash' boolean argument to the function
4192 silc_hash_table_alloc to indicate whether the hash table should
4193 auto-rehash when it thinks is appropriate time. It will
4194 increase the hash table size if the there is twice as much
4195 entries in the table than the size of the table, and will
4196 decrease the size if there are twice as less entries than
4197 the size of the table.
4199 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4203 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * silc_idcache_purge_by_context deletes the entry now by context
4206 as it is supposed to do. Affected file lib/silccore/idcache.c.
4208 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4209 client is not anymore valid (WHOWAS givens the info) and not
4210 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4212 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Removed the `data' and `data_len' arguments from the ID Cache
4215 interfaces and added `name' argument. ID Cache does not handle
4216 anymore the binary data only a names associated with given ID.
4218 * When hashing a Client ID with silc_hash_id the entire ID is
4219 not hashed anymore, instead only the hash of the Client ID is
4220 hashed. This way we can access the Client ID from the cache
4221 with Client ID but with the hash of the ID (which is a hash of
4222 the nickname) as well without any difference in performance.
4224 Added also silc_idcache_find_by_id_one_ext to do one on one
4225 searching when we have the actual ID. Added also function
4226 silc_hash_client_id_compare. The affected files are
4227 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4229 * When hashing the name associated with a ID it is always done
4230 in lowercase. This way we can access the cache without worrying
4231 about case-sensitivity, even though, for example nicknames are
4234 * Fixed a bug in server with channel message sending. It put
4235 wrong ID type as destination ID. The affected file
4236 silcd/packet_send.c.
4238 * silc_idcache_del_by_context now deletes from all hash tables
4239 by context. Affected file lib/silccore/idcache.c.
4241 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Changed the client library to use the new ID Cache interface.
4244 Changes around the source tree.
4246 * Added silc_hash_table_rehash_ext to rehash with specific
4247 hash function. Affected file lib/silcutil/silchashtable.[ch].
4249 * Added silc_hash_string_compare to compare two strings in the
4250 hash table. Affected file lib/silcutil/silcutil.[ch].
4252 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4254 * Added new function silc_idcache_del_by_context into the
4255 lib/silccore/idcache.[ch].
4257 * Changed the server's ID list routines to use the new ID Cache
4258 interface. Changes around the source tree.
4260 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Added silc_hash_table_del[_by_context]_ext functions in to the
4263 lib/silcutil/silchashtable.[ch].
4265 Removed silc_hash_table_find_all* routines and added new
4266 silc_hash_table_find_foreach to replace them.
4268 Added silc_hash_table_replace_ext function as extended
4269 replacing function. Separated the simple hash table interface
4270 from the extended hash table interface in the file
4271 lib/silcutil/silchashtable.h.
4273 * Fixed minor bugs and changed it to use some of the new
4274 hash table functions in lib/silccore/idcache.c
4276 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Added new function silc_hash_table_find_all to return all keys
4279 in the hash table by the specified key. As the hash table is
4280 collision resistant it also makes it possible to have several
4281 duplicate keys in the hash table. This function may be used to
4282 find all of the keys from the hash.
4284 Added user_context arguments to the SilcHashFunction,
4285 SilcHashCompare and SilcHashDestructor to deliver user specified
4288 Added new fuctions silc_hash_table_find[_all]_ext to do
4289 extended lookup with specified hash and compare functions and
4290 specified user contexts.
4292 Added new function silc_hash_table_add_ext to add the key
4293 with specified hash function and user context.
4295 Added new function silc_hash_table_foreach to traverse all
4296 entrys in the hash table. Added SilcHashForeach callback
4299 Added new function silc_hash_table_del_by_context to delete
4300 the entry only if the context associated with the key matches.
4302 Affected files are lib/silcutil/silchashtable.[ch].
4304 * Removed silc_hash_[server/client/channel]_id and added just
4305 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4306 silc_hash_id_compare to compare two ID's using as the hash table
4307 comparison function. Added also silc_hash_data to hash
4308 binary data and silc_hash_data_compare to compare it.
4310 * Removed silc_idlist_find_client_by_hash as it is not needed
4311 anymore. Affected file silcd/idlist.[ch].
4313 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4314 to use internally the SilcHashTable. The new ID Cache is a lot
4315 faster than the old one. Some of the ID Cache interface was also
4316 rewritten and obsolete and stupid functions were removed.
4318 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4320 * Added entry_count field to the SilcHashTable to keep the number
4321 of the entries in the table. Implemented the function
4322 silc_hash_table_rehash. Added new function
4323 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4325 Fixed a minor bug in silc_hash_table_free.
4327 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4328 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4329 into the lib/silcutil/silcutil.[ch].
4331 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Implemented a collision resistant hash table into the
4334 lib/silcutil/silchashtable[ch]. See the header and the source
4335 for the SilcHashTable API.
4337 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * Merged dotconf version 1.0.2 into lib/dotconf.
4341 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Do not compile anything in lib/silcsim/* if the SIM support
4344 is not enabled. The tree should now compile without problems
4347 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4349 * Compiled the SILC under cygwin. Compiled and tested briefly
4350 without problems. More tests needed. The SIMs didn't compile
4353 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4355 * Fixed possible crash in silc_get_username in the
4356 lib/silcutil/silcutil.c.
4358 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Fixed a va_arg in silc/client_ops.c.
4362 * Oops, RC5 routines were named AES and caused some problems
4363 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4365 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Added new SilcIDIP structure into the lib/silccore/id.h and
4368 replaced the old `ip' fields from all SILC ID's to that type.
4369 This is a step towards IPv6 support.
4371 The silc_id_get_len takes now the ID as an extra argument.
4372 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4373 both IPv4 and IPv6 based ID's.
4375 The affected files are lib/silccore/id.[ch] and other files
4376 around the tree using these routines.
4378 * Removed the ID length arguments in server from various
4379 silc_server_send_notify_* routines -> they are not needed
4382 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4384 * Fixed memory leak in silc_encode_pem_file in the file
4385 lib/silcutil/silcutil.c.
4387 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Check minor version as well in the SKE. Affected files are
4390 silcd/protocol.c and lib/silcclient/protocol.c.
4392 * Added --identifier option to the server so that an identifier
4393 can be when creating the public key for the server. Affected
4394 file is silcd/silcd.c.
4396 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4397 lib/silccrypt/silcpkcs.c.
4399 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Register default ciphers and stuff when using -C option with
4402 the server. Affected file sildc/silcd.c.
4404 * Put back the servers public key filename format, it is better
4405 than the new one. For now, the client keys are saved with the
4406 new filename format. The affected file silc/client_ops.c.
4408 * Implemented the Cipher API for the rest of the ciphers that
4409 did not implement it or implemented it the wrong way.
4411 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Register default ciphers and stuff when using the -S option
4414 in the client. Affected file silc/silc.c. Same also when
4415 creating new key pair with -C option.
4417 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Fixed the silc_verify_public_key client operation function to
4420 save the public keys differently. The fingerprint is now
4421 used as filename and not the hostname. This way also the
4422 client keys are saved uniquely and not with hostnames. The
4423 affected file is silc/client_ops.c.
4425 * Trimmed the silc_hash_fingerprint function to remove extra
4426 whitespaces from the end of the fingerprint. The affected
4427 file is lib/silccrypt/silchash.c.
4431 * Added silc_cipher_register_default function to register all
4432 default ciphers. It can be used when configuration files
4433 does not exist and the application does not want any specific
4434 ciphers in any specific order.
4436 The SilcDList is now used as silc_cipher_list dynamically
4437 allocated cipher list. Removed the static list all together
4438 and now all ciphers must be allocated to the dynamic list.
4439 The silc_cipher_alloc routine was changed to check only the
4442 All silc_cipher_* routines that used to return int returns
4445 The affected files lib/silccrypt/silccrypt.[ch].
4447 * The same thing was done to silc_hash_* as for silc_cipher_*
4448 routines. Affected files lib/silccrypt/silchash.[ch].
4450 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4451 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4452 Added also silc_pkcs_[un]register[_default] functions.
4453 Removed the data_context from the PKCS API.
4455 * Added silc_hmac_register_default function to register default
4456 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4457 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4458 to unregister all hmacs at once.
4460 * Register the default ciphers, hash functions, PKCSs and HMACs
4461 if client's configuration file does not exist. The affected
4464 * The client did not load the hash functions from the SIM
4465 modules at all. Added support for this. Affected file is
4466 silc/clientconfig.c.
4468 * When decoding public key with silc_pkcs_public_key_decode, check
4469 the supported algorithm only if PKCS are registered. Affected
4470 file lib/silccrypt/silcpkcs.c. The same was done with the
4471 silc_pkcs_private_key_decode.
4473 * Fixed the SILC List routines to keep the list always in order.
4474 It used to change the list's order when traversing the list but
4475 not it preserves the order. Affected file lib/trq/silclist.h.
4477 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * Added the client library to use the SilcSocketConnection's
4480 reference counter (by silc_socket_dup) to prevent the bug that
4481 the socket object may be freed underneath async operation.
4483 * The name resolv library checking fixes in the configure.in.pre.
4486 * Created new version of the protocol drafts for future
4487 development. The -03 drafts are the ones that will be changed
4488 in the trunk now and the -02 will remain as they are.
4490 * Send list of CUMODE notifys to the router when announcing
4491 the channel users to the router. Affected file silcd/server.c.
4492 If the router receiving channel founder CUMODE for a channel
4493 that already has channel founder it will send CUMODE notify
4494 to the sender to remove the channel founder rights from the
4495 announced client. Affected file silcd/packet_receive.c.
4497 * The CUMODE notify may now use Server ID as well as the entity
4498 who changes the mode. Updated protocool specs.
4500 * Updated INSTALL and README files.
4502 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * New web pages in the http://silc.pspt.fi. The pages was
4509 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4511 * Implemented the [DenyConnectin] config section in the server.
4512 Added silc_server_config_denied_conn to check whether incoming
4513 connection is denied. Affected file silcd/serverconfig.[ch].
4515 * Do not check the ports when checking the incoming configuration
4516 data if the port is 0, meaning any. Affected file is
4517 silcd/serverconfig.c.
4519 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Fixed buffer overflow in silc_string_compare in the file
4522 lib/silcutil/silcutil.c.
4524 * Fixed double free in silc_server_command_leave in the file
4527 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Fixed the version checking in the server. Affected file is
4532 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Fixed the configuration data fetching when accepting new
4535 connections in the server. Affected file silcd/server.c.
4537 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Added `sender_entry' argument to the function
4540 silc_server_packet_relay_to_channel so that we can check
4541 whether some destination actually belongs to the same route
4542 the sender belongs (ie, we must not resend the packet to the
4543 sender). Affected file silcd/packet_send.[ch].
4545 * Added `servername' field to the SilcClientEntry in the server
4546 to hold the name of the server where client is from. Affected
4547 file is silcd/idlist.h.
4549 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4551 * Moved the channel message encrypting in the router betwen
4552 router connections from silc_server_channel_message to the
4553 silc_server_packet_relay_to_channel since we want to check
4554 whether we have anybody channel before encrypting anything.
4555 Affected files silcd/packet_[receive/send].c.
4557 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Fixed the [AdminConnection] server config section to support
4560 multiple entries. Affected file silcd/serverconfig.c.
4562 * Added support into the server to check the validity of the
4563 incoming connection before executing any KE or authentication
4566 * The connection configuration is now saved to the KE and
4567 connection auth protocol contexts and not fetched anymore in
4568 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4570 * The local hosts listenning address and port is also resolved
4571 now when starting the server. We want to have the socket object
4572 to include the real address and port for the listener. Added
4573 new function silc_net_check_local_by_sock into the files
4574 lib/silcutil/silcnet.[ch].
4576 * Fixed a broadcast bug in server -> do not broadcast if we
4579 * Fixed a routing bug. Do not route broadcast packets ever.
4580 Broadcast packets must be processed always and not routed since
4581 they may be destined to some other host than yourself and thus
4582 would get routed without no good reason. Affected file is
4585 * Added function silc_server_config_is_primary_route to check
4586 whether primary router connection has been configured (a router
4587 configuration that we are initiating). If there is not, we
4588 will assume that there is only two routers in the SILC network
4589 and we will use the incoming router connection as our primary
4590 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4592 * Changed the order of the broadcasting. Broadcast _after_ the
4593 packet has been processed not before. Affected file is
4596 * Fixed a [ClientConnection] parsing bug. The port was never
4597 parsed correctly thus resulting to port 0. Affected file
4598 silcd/serverconfig.c.
4600 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4601 argument and did not set the broadcast packet flag. Affected
4602 file silcd/packet_send.c. Fixed same bug in the function
4603 silc_server_send_notify as well.
4605 * If we receive NEW_ID packet for our own ID in the server, ignore
4608 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Removed the nickname from the Private Message Payload.
4613 Updated the code and the protocol specs.
4615 * Updated protocol specs for submitting to the IETF.
4617 * Tweaked the Random Number Generator a bit. Affected file
4618 lib/silccrypt/silcrng.c. Exported a new function
4619 silc_rng_[global]_add_noise which can be used to add more
4622 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Do not parse packets with different timeout when protocol
4625 is active -> may cause problem with rekey. Affected file
4628 * When server receives signoff notify it must not create
4629 new channel key if the client is on any channels since the
4630 sender of the signoff notify will create it.
4632 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Added printing of error messages during SKE protocol from the
4635 failure packet sent by server during SKE. Affected file
4638 * Removed the client's failure_callback handling with timeout
4639 and handle it immediately when received.
4641 * The SKE library returned wrong type in SUCCESS and FAILURE
4642 packets. They must be 32 bit MSB not 16 bit MSB.
4644 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Ok, rewrote the logic of the re-key and now it seems to work.
4647 I tested it on high traffic with frequent re-keys without
4648 problems. Added hmac_receive (and renamed hmac to hmac_send)
4649 in SilcClientConnection in lib/silcclient/client.h and
4650 in SilcIDListData in silcd/idlist.h. Also, removed the
4651 SilcPacketParserContext's cipher and hmac fields as they are
4652 not needed anymore and actually caused some problems when
4653 the ciphers and hmac's changed underneath the packet parser.
4655 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * If re-key protocol is active then process the incoming packets
4658 synchronously since we must assure that icoming packets encrypted
4659 with the old key is processed before the new keys is set to
4660 use. This is true other packets than for REKEY packets.
4661 Affected file silcd/server.c. The same was done to client library
4662 as well, affected file lib/silcclient/client.c.
4664 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * Fixed bug in client and server to accept the force send if
4667 the packet is send from silc_[server/client]_packet_process
4668 function. Otherwise the packets are never delivered, oops.
4670 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Disable force sending of packets when REKEY protocol is active.
4673 We must assure that no packet is sent directly when rekey is
4674 performed. All packets must be sent through packet queue.
4675 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4676 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4677 function is silc_[server/client]_packet_send_real to check
4680 * Replaced the SIM paths from example config files to
4681 /usr/local/modules. Also, make install creates now
4682 /usr/local/silc/logs directory to hold all the SILC server
4685 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4687 * Made the configure.in.pre work on Solaris. Patch by salo.
4689 * Made all ciphers compatible with non-x86 machines. Defined
4690 CBC mode macros into lib/silccrypt/ciphers_def.h.
4692 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4694 * Fixed the make install.
4696 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * When MAC computation fails the silc_packet_decrypt returned 0
4699 even though it was supposed to return -1. Fixed this. The
4700 affected file is lib/silccore/silcpacket.c.
4702 * Do not replace the config files in /etc/silc (in make install)
4703 if they already exist. Affected file ./Makefile.am.
4705 * Do not send re-key packets immediately but through packet queue.
4706 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4708 * Changed silc_net_check_host_by_sock to return FALSE if the
4709 IP/DNS could not be resolved. Though, it returns the IP address
4710 now even if it could not resolve it (but returns also FALSE).
4711 Affected file lib/silcutil/silcnet.[ch].
4713 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Added silc_pkcs_decode_identifier to decode the public key's
4716 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4717 Added also silc_pkcs_free_identifier. Added also new context
4718 SilcPublicKeyIdentifier.
4720 * Added -S option to the silc client. It is used to dump the
4721 contents of the specified public key file.
4723 * Changed the PKCS api to return the public key length when
4724 setting the public key.
4726 * Fixed a fatal bug in the public and private key file loading.
4727 Affected file lib/silccrypt/silcpkcs.c.
4729 * Execute the packet parsing for client with zero (0) timeout
4730 if the protocol is active. Affected file silcd/server.c.
4732 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Made the key generation options to the silcd program. Added
4735 -C option, equivalent to client's option.
4737 * Added new [ServerKeys] config section to the server. It
4738 configures the server's public and private key.
4740 * Defined generic Public Key Payload into the protocol
4741 specification to send specific type of public keys and
4744 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4745 public key or certificate.
4747 * Implemented the GETKEY command to the server and to the
4748 client library and on user interface.
4750 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4752 * Made preliminary `make install' work.

4756 * Added SilcServerRekey context into silcd/idlist.h.
4758 * Added the PFS support as defined in the specification to the
4759 SKE protocol. Affected files lib/silcske/*.c.
4761 * Added `ske_group' field to the SilcServerRekey context to hold
4762 the number of the SKE group that is used with PFS in re-key.
4763 Affected file silcd/idlist.h.
4765 * Added PFS re-key support to the server. Affected file is
4768 * Added silc_protocol_cancel to cancel execution of the next
4769 state of the protocol. Affected file is
4770 lib/silccore/silcprotocol.[ch].
4772 * Added the re-key support with and without PFS to the client
4773 library. Re-key is performed once in an hour, by default.
4775 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4776 Added silc_client_rekey_callback and silc_client_rekey_final.
4777 Affected files are lib/silcclient/protocol.[ch] and
4778 lib/silcclient/client.[ch].
4780 * Removed the `hmac_key' and `hmac_key_len' fields from the
4781 SilcClientConnection structure; not needed. Affected file is
4782 lib/silcclient/client.h.
4786 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4788 * Do not ask whether user wants to use the negotiated private key
4789 for private messages, just use it. Affected file is
4790 silc/local_command.c.
4792 * Added `send_enc_key' and `enc_key_len' fields to the
4793 SilcIDListData structure since they are needed in the re-key
4794 phase. Affected file is silcd/idlist.[ch].
4796 * Implemented the simple re-key protocol into the server.
4797 Affected files silcd/server.c and silcd/protocol.[ch]. The
4798 re-key will be performed once in an hour, by default.
4800 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4801 Added silc_server_rekey, silc_server_rekey_callback and
4802 silc_server_rekey_final.
4804 * Removed Tunneled flag from the protocol. Updated the code
4805 and the specifications.
4807 * Adde `pfs' field to the SilcIDListData to indicate whether
4808 the PFS is to be performed in the re-key. Affected file is
4811 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4814 int64 of at least the xintXX size. If void * is less that 4
4815 bytes uint32 * will be used. Defined bool as boolean.
4817 * Changed _ALL_ unsigned long and unsigned int to uint32,
4818 unsgined short to uint16 in the source tree.
4820 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4821 not handle clients that has entry->data.registered == FALSE.
4822 They are not in the network anymore. Affected file is
4825 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4827 * Implemented the sending of the SERVER_SIGNOFF notify in the
4828 server. Affected file is silcd/server.c.
4830 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4831 Added also silc_notify_payload_encode_args into the
4832 lib/silccore/silcnotify.[ch].
4834 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4835 Affected file silcd/packet_receive.c.
4837 * Implemented the SERVER_SIGNOFF notify handling in the client
4838 library. Affected file lib/silcclient/client_notify.c. Also,
4839 implemnted the printing of the SERVER_SIGNOFF info to the
4840 application. Affected file silc/client_ops.c.
4842 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4843 if the deleting was successful. Affected file silcd/idlist.[ch].
4845 * Added support for public key authentication in the connection
4846 authentication protocol in the client library. Affected file
4847 lib/silcclient/protocol.c.
4849 * Changed the server's silc_idlist_get_clients_by_* interface
4850 to support already allocated array so that new entries may be
4851 added to pre-allocated array. Affected file silcd/idlist.[ch].
4852 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4853 and command replies.
4855 * All command reply functions in the server now calls the
4856 pending command callback even if error occured. This way the
4857 error will be delivered to the client as well. Affected files
4858 silcd/command.c and silcd/command_reply.c.
4860 * Fixed INFO command to return local server's info if no server
4861 was provided. Affected file lib/silcclient/command.c.
4863 * Removed RESTART command for good. Updated the code and the
4866 * Rewrote parts of the task system. It is a bit simpler now.
4867 Removed unsued task priorities. The affected files are
4868 lib/silcutil/silctask.[ch].
4870 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4872 * Moved the USERS printing from the library to the application.
4873 Affected files lib/silcclient/command.c and silc/client_ops.c.
4875 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Added channel key re-key support. The re-key is perfomed
4880 only by the router and is done once in an hour. Added `rekey'
4881 field to the SilcChannelEntry in the server. Affected files
4882 silcd/server.c and silcd/idlist.h.
4884 * Added silc_task_unregister_by_context into the file
4885 lib/silcutil/silctask.[ch].
4887 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Added SILC_UMODE_GONE mode to indicate when the client is not
4890 present in the SILC network. Added also support to the local
4891 command AWAY that will set this mode. Added support of showing
4892 "xxx is gone" in WHOIS command. The USERS command shows the
4893 gone status as well.
4895 * Fixed setting server and router operator privileges in the
4896 server's UMODE command. Affected file silcd/command.c.
4898 * Merged the SKE KE1 and KE2 payloads into one payload. The
4899 new KE payload is equivalent to the old KE2 payload.
4901 Cleaned up the SKE Start Payload parsing. It now uses the
4902 simple buffer unformatting to do the parsing. A lot faster
4905 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4906 to the SKE that is used to indicate whether both of the SKE
4907 parties should perform authentication. By default only the
4908 responder performs authentication. By setting this flag also
4909 the initiator must do authentication. By default it is unset
4910 since in normal SKE case, client to server connection, only
4911 the responder should do authentication. When doing SKE between
4912 two clients both should perform authentication. Updated the
4913 code and the protocol specs.
4915 * A little fix to IDENTIFY command in the server. Search the
4916 client first by hash not nickname. Affected file is
4919 * Fixed the silc_client_close_connection to support closing
4920 the client to client connections wihtout deleting too much
4921 data. Affected file lib/silcclient/client.c.
4923 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4924 are received if protocol used to be active but is not anymore
4925 the application would crash due to NULL pointer dereference.
4926 Affected files silcd/server.c and lib/silcclient/client.c.
4928 * Added `hash' field to the SilcClientConnection to include
4929 the hash function negotiated in the SKE protocol.
4931 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4932 to set the channel founder authentication data. A client can
4933 claim the founder rights later by providing the authentication
4934 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4935 This way the channel founder can regain the channel founder
4936 privileges even it is left the channel. This works only on
4937 local server and the client must be connected to the same
4938 server to be able to regain the founder rights. Updated the
4939 protocol specs accordingly.
4941 Added support to the CMODE command in the client to set the
4942 founder auth data. Read the README to see how to set it.
4944 Added support to the CUMODE command to claim the founder
4945 rights. Read the README to see how to do it.
4947 Added support for the founder authentication to the Channel
4948 Entry in the server. Affected file silcd/idlist.h.
4950 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4951 server's CMODE command. Affected file silcd/command.c.
4953 * Added the following new functions into lib/silccore/silcauth.[ch]:
4954 silc_auth_get_method and silc_auth_get_data.
4956 * The server now saves the remote hosts public key to the
4957 SilcIDListData pointer. Affected file silcd/protocol.c.
4959 * The normal server now does not remove the channel entry from
4960 the cache if the founder authentication data is set. It used
4961 to remove it if the founder was the last one on the channel on
4962 the server and left the channel. The auth data is saved and
4963 if the channel is re-joined later the old entry is used with
4964 the old auth data. Affected files silcd/command_reply.c and
4967 * Removed the `pkcs' field from the SilcIDListData structure
4968 in the server; it is not used. Affected file silcd/idlist.h.
4970 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4972 * Fixed packet processing on slow links. Partial packets were
4973 never re-processed because the incoming data buffer was cleared
4974 by the application. Application must not directly clear the
4975 sock->inbuf, the packet processing routines handle it. Fixed
4976 this in client library and in server.
4978 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Fixed the WHOIS and IDENTIFY send reply function to really
4981 check whether to send list or just one entry. Affected file
4984 * Cleaned up the LEAVE command's channel key distribution. The
4985 affected file silcd/command.c.
4987 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4988 can enforce the channel mode as well. In that case the ID
4989 includes the ID of the server. The code now enforces the
4990 mode change if the router have different mode than the server.
4992 * The notify client operation with CMODE_CHANGE notify can now
4993 return NULL client_entry pointer if the CMODE was not changed
4994 by client. Application must check for this.
4996 * Added <Server ID> argument to INFO command to support server
4997 info fetching by Server ID.
4999 * Added silc_server_announce_get_channel_users to get assembled
5000 packets of channel users of the specified channel. Affected
5001 file silcd/server.[ch].
5003 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5004 was freed underneath the ID Cache.
5006 * Re-announce clients when the server received CHANNEL_CHANGE
5007 notify from the router. Affected file silcd/packet_send.c.
5009 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5012 crashed since it did not handle the fact that there is no cipher
5013 called "3" and didn't check the error condition. Now fixed.
5015 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5016 flag. It can be used to send message requests.
5018 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * Implemented the RESTART command in the client.
5022 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5023 notice type messages. Added notice printing to the user
5026 * The channel keys are not re-generated if the channel's mode
5027 is PRIVKEY, ie private key on the channel exists. Affected
5028 files silcd/server.c and silcd/command.c.
5030 * Fixed a little bug in channel message delivery when channel
5031 private keys are set in the server. Affected file is
5032 silcd/packet_send.c.
5034 * Changed the setting on channel->on_channel = TRUE from the
5035 silc_client_save_channel_key to the JOIN command reply. The
5036 key payload is not received if the private channel key is set.
5037 Affected file lib/silcclient/command_reply.c and the
5038 lib/silcclient/client_channel.c.
5040 * When the CMODE_CHANGE notify is sent and the channel private
5041 key mode is removed the channel key must be re-generated in
5042 other cells as well. Added this support for the router in the
5043 silcd/packet_receive.c.
5045 * Added new local command NOTICE to send notice message on
5046 channel. Affected file silc/local_command.[ch].
5048 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5050 * Added new local command ME to the client. It is used to send
5051 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5052 some action. Affected file silc/local_command.[ch].
5054 * Changed channel_message and private_message client operations
5055 to deliver the message flags to the application. Added also
5056 the `flags' arguments to the silc_client_send_channel_message
5057 and silc_client_send_private_message functions. Affected file
5060 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Redefined the Private Message Payload to support private message
5063 keys and to support the new private message flags. Updated
5064 the protocol specs. Flags makes it possible to have for example
5065 CTCP style messages.
5067 * Added new type SilcPrivateMessagePayload and defined an API
5068 for it in the lib/silcclient/silcprivate.[ch].
5070 * Tested private message private keys successfully. Tested the
5071 private message key set, unset and list commands with the new
5074 * Redefined the Channel Message Payload to include the channel
5075 message flags (equal with private message flags) to support
5076 for example CTCP style messages.
5078 * Defined some of the message (for channel and private message)
5079 flags. Updated the protocol specs and added the flags to the
5080 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5082 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * Added SilcKeyAgreementStatus type to the key agreement routines
5085 to indicate the current status and error if one occured.
5086 The status types are defined in the lib/silcclient/silcapi.h.
5088 * Added new local command KEY that is used to set and unset private
5089 keys for channels, set and unset private keys for private messages
5090 with remote clients and to send key agreement requests and
5091 negotiate the key agreement protocol with remote client. The
5092 key agreement is supported only to negotiate private message keys,
5093 it currently cannot be used to negotiate private keys for channels,
5094 as it is not convenient for that purpose.
5096 * Fixed a minor pending callback setting bug in the function
5097 silc_client_get_client_by_id_resolve, now the function works.
5098 Affected file lib/silcclient/idlist.c.
5100 * Added function silc_net_get_local_port to get local bound
5101 port by socket. Added to lib/silcutil/silcnet.[ch].
5103 * Added `sockets' and `sockets_count' fields to the SilcClient
5104 object. They hold the sockets of the listenning sockets in
5105 the client. Listenning sockets may be for example the key
5106 agreement server. Affected file lib/silcclient/client.[ch].
5107 Added functions the silc_client_add_socket and the
5108 silc_client_del_socket. They are exported to the application
5111 * Added ~./silc/clientkeys to support other client's public keys.
5113 * Renamed verify_server_key client operation to verify_public_key
5114 and added one argument to indicate the type of the connection
5115 (server, client etc.).
5117 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Added silc_server_connection_auth_request to handle the
5120 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5121 silcd/packet_receive.[ch].
5123 * Added silc_server_send_connection_auth_request into the
5124 silcd/packet_send.c to send the connection auth request packet.
5126 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5129 * Fixed the public key authentication in responder side in the
5130 server. The `auth_data' pointer includes the SilcPublicKey
5131 not the path to the public key. Affected file silcd/protocol.c.
5133 * Implemented the public key authentication in the initiator side
5134 in the server. Affected file silcd/protocol.c.
5136 * Removed the [RedirectClient] config section from the server
5137 configuration. Is not needed and I don't want to implement it.
5139 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Cleaned up the CMODE command in the server. It now works
5142 correctly and supports all the modes defined in the protocol.
5143 Affected file is silcd/command.c.
5145 * Added `hmac_name' field to the SilcChannelEntry in the server
5146 to hold the default HMAC of the channel. It can be set when
5147 creating the channel (with JOIN command). Affected files
5150 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5151 type to indicate the change of the current cipher and hmac
5152 on the channel. Client can safely ignore the <cipher> argument
5153 (if it chooses to do so) since the CHANNEL_KEY packet will
5154 force the channel key change anyway. The <hmac> argument is
5155 important since the client is responsible of setting the new
5156 HMAC and the hmac key into use.
5158 * Fixed the CMODE command in the client library as well.
5160 * Tested CMODE command in router environment successfully.
5162 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Show the version of the remote client (or server) when connecting
5165 to the server. It is logged to the log file. Affected file
5166 is silcd/protocol.c.
5168 * Fixed the KILLED notify handling in the client library. The
5169 client must be removed from all channels when receiving the
5172 Also, do not remove the client entry when giving the KILL
5173 command but when the KILLED notify is received.
5175 * Removed silc_idlist_find_client_by_nickname from the server.
5176 Not needed anymore. Affected files silcd/idlist.[ch].
5178 * Implemented the CHANNEL_CHANGE notify type handling to the
5179 server. Affected file silcd/server.c.
5183 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5185 * Added silc_server_send_notify_invite to send the INVITE
5186 notify between routers.
5188 * Implemented the INVITE command correctly to the server.
5190 * Implemented the INVITE notify type handling in the server.
5192 * Implemented the INVITE command to the client library and on the
5195 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Added function silc_server_get_client_resolve to find the
5198 client entry by ID from all ID lists and then resolve it
5199 (using WHOIS) if it cannot be found. Affected file is
5202 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Implemented the BAN command to the client library.
5206 * The JOIN command in the server now checks the invite list
5209 * Changed the silc_command_reply_payload_encode_va and the
5210 silc_command_payload_encode_va to support that if argument is
5211 NULL it ignores and checks the next argument. Affected file
5212 lib/silccore/silccommand.c.
5214 * Added silc_server_send_notify_ban to send the BAN notify
5215 type between routers.
5217 * Chaned the silc_notify_payload_encode to support that if
5218 argument is NULL it ignores and checks the next argument.
5219 Affected file lib/silccore/silcnotify.c.
5221 * Tested ban lists in router environment successfully.
5223 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * Implemented BAN command to the server, in silcd/command.[ch].
5227 * Removed the BAN and INVITE_LIST modes from the CMODE command
5230 * Added function silc_string_match to regex match two strings.
5231 Affected files lib/silcutil/silcutil.[ch].
5233 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Redefined parts of the SilcChannelEntry in the server to support
5236 the new ban and invite lists.
5238 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5240 * Redefined the INVITE command. The same command can be used to
5241 invite individuals to the channel but also to manage the invite
5242 list of the channel (to add to and remove from the invite list).
5243 Updated the protocol specs.
5245 * Added new command SILC_COMMAND_BAN that can be used to manage
5246 the ban list of the channel. Updated the protocol specs.
5248 * Removed the channel modes: the SILC_CMODE_BAN and the
5249 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5250 in the CMODE command. The equivalent features are now available
5251 using INVITE and BAN commands. Updated the protocol specs.
5253 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5254 in the network about change in the current ban list. The notify
5255 type is not used by the client.
5257 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5258 support the invite lists.
5260 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Added new function silc_string_regexify that converts string
5263 including wildcard characters into regex string that can
5264 be used by the GNU regex library. Added into the file
5265 lib/silcutil/silcutil.[ch].
5267 Added silc_string_regex_combine to combine to regex strings
5268 into one so that they can be used as one regex string by
5269 the GNU regex library. Added into the file
5270 lib/silcutil/silcutil.[ch].
5272 Added silc_string_regex_match to match two strings. It returns
5273 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5275 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5277 * Imported GNU regex to the soruce tree into lib/contrib.
5278 Fixed some compiler warning from the regex.c.
5280 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Fixed MOTD command in the server to work in router environment.
5284 * Fixed the MOTD command in the client library to support
5285 the server argument in the command.
5287 * Added `nickname_len' argument to the silc_idlist_add_client
5288 in the server, as the `nickname' argument may be binary data
5291 * Added silc_idlist_get_channels to return all channels from
5294 * Implemented LIST command to the server. Affected file is
5297 * Implemented the LIST command to the client library and on the
5300 * Added [<user count>] argument to the LIST command reply.
5301 With private channels the user count is not shown.
5303 * Updated TODO and README.
5305 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * The client entry's data.registered must be TRUE even with
5308 global client entry on global client list. The data.registered
5309 is used to check whether the client is anymore in the network,
5310 for example with WHOWAS command so it must be valid.
5312 * Fixed the WHOWAS command in the server. It now actually works
5313 in router environment. Added function into silcd/command_reply.c
5314 silc_server_command_reply_whowas_save.
5316 * Added silc_idlist_purge function to the silcd/idlist.c
5317 to periodically purge the ID Cache.
5319 * Fixed INFO command in the server. It works now in router
5320 environment. Added <server name> argument to the INFO command
5321 reply. Updated the protocol specs.
5323 * Fixed minor bug in silc_idcache_purge to not purge if the
5324 expire value is zero.
5326 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5327 they were buggy because of the WHOWAS information.
5329 * Fixed local command MSG to handle the async resolving of
5330 the remote client properly. It used to fail the first MSG.
5331 Affected file silc/local_command.c.
5333 * Added `data_len' field to SilcIDCache context.
5335 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Update TODO. Todo in commands in the server.
5339 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5341 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5342 used by routers as broadcast packet to inform other routers
5343 about the changed user mode.
5345 Implemented the notify handling in the server. Affected file is
5346 silcd/packet_receive.c. Added the function
5347 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5349 * Added new generic Channel Payload and deprecated the New Channel
5350 Payload. The New Channel Payload is now the generic Channel
5353 * Added new argument `mode' to the silc_server_send_new_channel
5354 as it is required in the Channel Payload now.
5356 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5357 and created a new and real SilChannelPayload to represent the
5358 new generic Channel Payload. Implemented the encode/decode
5359 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5361 * Added silc_server_get_client_channel_list to return the list
5362 of channels the client has joined for WHOIS command reply.
5363 Affected file silcd/server.[ch].
5365 * Implemented the channel list sending in the WHOIS command reply
5366 in server and in the client.
5368 Implemented the channel list displaying on the user interface
5369 as well. Affected file silc/client_ops.c.
5371 * Added silc_channel_payload_parse_list to parse list of Channel
5372 Payloads. It returns SilcDList list of SilcChannelPayloads.
5373 Client for example can use this function to parse the list of
5374 channels it receives in the WHOIS command reply. The caller
5375 must free the list by calling silc_channel_payload_list_free.
5376 Affected files lib/silccore/silcchannel.[ch].
5378 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Added one new argument <user mode> to the WHOIS command reply
5381 to return the mode of the user in SILC. Updated the protocol
5384 Implemented it to the server and client.
5386 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Fixed the mode printing on the user interface on joining.
5389 Affected file silc/client_ops.c.
5391 * Implemented the UMODE command and user modes in general to the
5392 client library and to the user interface.
5394 * Implemented the UMODE command to the server.
5396 * The server now sends UNKNOWN_COMMAND error status if client sends
5397 unknown command. Affected file silcd/command.c.
5399 * All server commands now handle the command identifier the right
5400 way when sending the command reply to the client. The client can
5401 use to identify the command replies with the identifier.
5403 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5405 * Added silc_server_get_client_route to resolve the route to
5406 the client indicated by the client ID. Affected file is
5409 * Added silc_server_relay_packet as general function to relay
5410 packet to arbitrary destination. This deprecates functions
5411 like _send_private_message_key, _relay_notify etc. Affected
5412 file is silcd/packet_send.[ch].
5414 Removed silc_server_send_key_agreement,
5415 silc_server_send_private_message_key and
5416 silc_server_packet_relay_notify functions from the file
5417 silcd/packet_send.[ch].
5421 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5422 server. Affected file silcd/packet_receive.[ch].
5424 * Implemented the KILL command to the client. Implemented the
5425 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5426 Affected files lib/silcclient/command[_reply].c and
5427 lib/silcclient/client_notify.c. Implemented the KILL notify
5428 printing in the user inteface.
5430 * Fixed a lot silc_parse_nick memory leaks from the client
5431 library in the file lib/silcclient/command.c.
5433 * Changed the silc_server_send_notify_on_channels's `sender'
5434 argument from SilcSocketConnection to SilcClientEntry to
5435 check the sender as entry and not as connection object and not
5436 to send to the client provided as argument. The affected file
5437 is silcd/packet_send.[ch].
5439 * The notify packets that are destined directly to the client used
5440 to not to be processed by the server. Now changed that and the
5441 server processes all notify packets. After relaying the packet
5442 to the client the notify packet is processed in the server.
5444 * The silc_server_free_client_data now checks whether there is
5445 pending outgoing traffic for the client and purges the data to
5446 the network before removing the client entry.
5448 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5451 an client is killed from the SILC Network. Updated the protocol
5454 Added new function silc_server_send_notify_killed to the
5455 silcd/packet_send.[ch].
5457 * Added function silc_server_packet_relay_notify to relay notify
5458 packets that are destined directly to a client. In this case
5459 the server does not process the notify packets but merely relays
5460 it to the client. Affected file silcd/packet_send.[ch].
5462 Added also silc_server_packet_process_relay_notify to check
5463 whereto relay the notify. Affected file is
5464 silcd/packet_receive.[ch].
5466 * Implemented the KILL command to the server.
5470 * Added the backup schema desgined last fall to the protocol
5471 specs for everyone to see. The specification is in the
5472 *-spec-xx.txt draft and the packet type definitions for the
5473 backup routers is in *-pp-xx.txt draft. Thusly, added also
5474 new packet type SILC_PACKET_CELL_ROUTERS.
5476 * A big security problem in the implementation discovered. The
5477 signoff of an client did not cause new channel key generation
5478 which it of course should've done. The channel keys must be
5479 always re-generated when client leaves (or signoffs) the channel.
5480 The silc_server_remove_from_channels funtion now handles
5481 the channel key re-generation.
5483 * Added `sender' argument to the silc_server_send_notify_on_channels
5484 to not to send the client provided as argument. Affected file
5485 silcd/packet_send.[ch].
5487 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5489 * Implemented OPER and SILCOPER commands into the server and
5492 * Added silc_auth_verify and silc_auth_verify_data to verify
5493 the authentication directly from the authentication payload.
5494 It supports verifying both passphrase and public key based
5495 authentication. Affected file lib/silccore/silcauth.[ch].
5497 * Added `hash' field to the SilcIDListData structure. It is the
5498 hash negotiated in the SKE protocol. Affected file is
5501 * Slight redesigning of the SilcAuthPayload handling routines.
5502 Do not send SilcPKCS but SilcPublicKey as argument.
5504 * Implemented the public key authentication support to the
5505 serverconfig. The public key is loaded from the provided path
5506 and saved as authentication data to void * pointer. Thus,
5507 changed the unsigned char *auth_data to void *auth_data;
5509 * Fixed SHUTDOWN command to send the reply before the server
5510 is shutdown. :) Affected file silcd/command.c.
5512 * Fixed fatal bug in CONNECT command. The hostname was invalid
5513 memory and server crashed. Affected file silcd/command.c.
5515 * Fixed fatal bug in CLOSE command. The server_entry became
5516 invalid but was referenced later in the command. Affected file
5519 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5521 * Fixed fatal bug in failure packet handling. Server ignored
5522 the failure and thus crashed when it came.
5526 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5528 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5529 that the command may be executed only once in (about) 2 seconds.
5530 The old SILC_CF_LAG flag is same but allows command bursts up
5531 to five before limiting.
5533 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5534 server code. Various commands now includes the CF_LAG_STRICT
5535 flag to disallow any kind of miss-use of the command.
5537 * Fixed the silc_buffer_unformat to not to allocate any data
5538 if the length of the data is zero. It used to allocate the
5539 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5541 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Changed the format of AdminConnection configuration section
5544 in the server. Added username of the admin to the format.
5545 Affected files silcd/serverconfig.[ch].
5547 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5548 to return admin configuration data by host, username and/or
5551 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Implemented WHOWAS command to the server. Added the functions:
5555 silc_server_command_whowas_parse,
5556 silc_server_command_whowas_send_reply,
5557 silc_server_command_whowas_from_client and
5558 silc_server_command_whowas_from_server
5560 * Added <Client ID> argument to the WHOWAS command reply. Updated
5561 the protocol specs accordingly.
5563 * Implemented WHOWAS command and command_reply to the client
5566 Implemented the WHOWAS printing on the user interface.
5568 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5570 * Added new argument to the WHOWAS command reply, the real name.
5571 It is an optional argument. Updated the protocol specs.
5573 * Added SilcIDCacheDestructor callback that is registered when
5574 the SilcIDCache is allocated. The callback is called when
5575 an cache entry in the ID Cache expires, or is purged from the
5576 cache. Added into lib/silccore/idcache.[ch].
5578 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5579 to destruct the client entries when the cache entry expires.
5580 Other ID Cache's in server and in the client library ignores
5583 * If the ID Cache entry's `expire' field is zero then the entry
5584 never expires. Added boolean `expire' argument to the
5585 silc_idcache_add function in the lib/silccore/idcache.[ch].
5586 If it is TRUE the default expiry value is used.
5588 * Added silc_server_free_client_data_timeout that is registered
5589 when client disconnects. By default for 5 minutes we preserve
5590 the client entry for history - for WHOWAS command.
5592 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Added support to the server to enforce that commands are not
5595 executed more than once in 2 seconds. If server receives
5596 commands from client more frequently, timeout is registered
5597 to process the commands. Affected file silcd/command.c.
5598 Added new function silc_server_command_process_timeout.
5600 * Changed NICK_NOTIFY handling in client library to check that
5601 if the client's nickname was changed, so there is no need to
5602 resolve anything from the server.
5604 * Removed error printing from the WHOIS and IDENTIFY commands.
5605 If error occurs then it is ignored silently in the client library.
5606 The application, however, may map the received error to
5607 human readable error string. The application currently maps
5608 the NO_SUCH_NICKNAME error to string.
5610 * Made the command status message public to the application. Moved
5611 them from lib/silcclient/command_reply.c to
5612 lib/silcclient/command_reply.h. The application can map the
5613 received command status to the string with the
5614 silc_client_command_status_message function.
5616 * Added check to the server to check that client's ID is same
5617 as the Source ID in the packet the client sent. They must
5620 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5622 * Added dist-bzip hook to the Makefile.am to make bzip2
5623 compressed distributions.
5625 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5627 * Server now enforces the maximum length for the nickname and
5628 the channel as protocol specification dictates. 128 bytes for
5629 nickname and 256 bytes for channel name.
5631 * Moved the WHOIS printing to the application. The client libary
5632 does not print out the WHOIS information anymore, the application
5633 must do it. Renamed silc_client_command_reply_whois_print to
5634 the silc_client_command_reply_whois_save.
5636 The client's idle time is also sent to the application now, and
5637 the idle is shown on screen.
5639 * Added silc_client_command_reply_identify_save to save the
5640 received IDENTIFY entries.
5642 * Do not check for channel private keys in message sending and
5643 reception if the channel does not have the PRIVKEY mode set.
5644 Affected file lib/silclient/client_channel.c.
5646 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5648 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5649 just surfaced after chaning the JOIN procedure.
5651 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * Added silc_client_get_clients_by_list to get client entries
5654 from Client ID list, that is returned for example by JOIN
5655 and USERS command replies. The application should use this
5656 function for example when JOIN command reply is received to
5657 resolve the clients already on the channel (library does not
5658 do that anymore as USERS command reply is not used in the JOIN
5659 procedure anymore). Affected files lib/silcclient/silcapi.h and
5660 lib/silcclient/idlist.c.
5662 * JOIN command reply and USERS command reply returns now SilcBuffer
5663 pointers instead of unsigned char pointers when returning
5664 the client list and mode list.
5666 * Added <Client ID> argument to the JOIN command reply, mainly
5667 for the server to identify for which client the command was
5668 originally sent. Updated protocol specs accordingly.
5670 * Added SilcDlist private_key pointer to the SilcChannelEntry
5671 in the client to support the channel private keys. Affected
5672 file is lib/silcclient/idlist.h.
5674 * Added SilcChannelPrivateKey argument to the function
5675 silc_client_send_channel_message so that application can choose
5676 to use specific private ke if it wants to. If it is not provided,
5677 the normal channel key is used, unless private keys are set.
5678 In this case the first (key that was added first) is used
5679 as the encryption key.
5681 * Implemented the support for channel private key handling.
5682 Implemented the following functions:
5684 silc_client_add_channel_private_key,
5685 silc_client_del_channel_private_keys,
5686 silc_client_del_channel_private_key,
5687 silc_client_list_channel_private_keys and
5688 silc_client_free_channel_private_keys
5690 Affected file lib/silcclient/client_channel.c.
5692 * Added the support for the private keys in the channel message
5693 sending and encryption and in the message reception and
5694 decryption. Affected funtions are
5695 silc_client_send_channel_message and silc_client_channel_message.
5697 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5699 * Added SKE's key verify callback to the client library's
5700 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5702 * Removed the statement that server (or router) must send USERS
5703 command reply when joining to the channel so that the client
5704 knows who are on the channel. Instead, the client list and
5705 client's mode list is now sent in the JOIN command reply to the
5706 client who joined channel. This is better solution.
5708 * Added function silc_server_get_users_on_channel and function
5709 silc_server_save_users_on_channel to the silcd/server.[ch].
5711 * Removed function silc_server_command_send_users from the
5714 * Do not show topic on the client library anymore. The topic is
5715 sent in the command reply notify to the application and the
5716 application must show the topic now.
5718 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Added client searching by nickname hash into the IDENTIFY and
5721 WHOIS commands in the server as they were clearly missing from
5722 them. Affected file is silcd/command.c.
5724 * Fixed a bug in private message receiving in the client library.
5725 The remote ID was freed and it wasn't supposed, now it is
5728 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5730 * Minor fix to the channel payload; allocate the data area, as it
5731 needs to be of specific length.
5733 * If the key agreement port is zero then the operating
5734 system will define the bound port. Affected files are
5735 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5737 * Added new function silc_channel_payload_decrypt into the file
5738 lib/silccore/silcchannel.[ch].
5740 * Moved the channel message etc, check from silc_packet_decrypt
5741 to applications. The library calls now a generic
5742 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5743 when the packet is either normal or special. This was done to
5744 allow more wide range of checking that was not allowed when
5745 the code was in library. Now applications can do virtually any
5746 checks to the packet and return to the library the decision how
5747 the packet should be processed. Affected files are
5748 lib/silccore/silcpacket.[ch].
5750 Added silc_server_packet_decrypt_check to the server and
5751 silc_client_packet_decrypt_check to the client library.
5753 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5754 to send with specified source and destination information.
5756 * Channel message delivery between routers was broken after the
5757 channel key distribution was fixed earlier. The channel key
5758 was used be to distributed to other routers as well which is not
5759 allowed by the protocol. Now this is fixed and channel keys
5760 really are cell specific and the channel message delivery between
5761 routers comply with the protocol specification.
5763 * Fixed various commands in server to check also the global list
5764 for the channel entry and not just the local list. The affected
5765 file silcd/command.c.
5767 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5769 * Added assert()s to buffer formatting and unformatting routines
5770 to assert (if --enable-debug) when error occurs. Affected
5771 file: lib/silcutil/silcbuffmt.c.
5773 * Changed to auto-reconnect to check whether the remote host is
5774 router and register the re-connect timeout if it is. It used
5775 to check that whether we are normal server, but router must do
5776 auto-reconnect with another router as well. Affected file
5779 * Removed the [<key len>] option from CMODE command as the cipher
5780 name decides the key length, nowadays. See the defined ciphers
5781 from the protocol specification.
5783 * Added [<hmac>] option to the CMODE command to define the HMAC
5784 for the channel. Added SILC_CMODE_HMAC channel mode.
5786 * Added [<hmac>] option for the JOIN command so that user can
5787 select which HMAC is used to compute the MACs of the channel
5790 * Added Hmac field to the Channel Message Payload. The integrity
5791 of plaintext channel messages are now protected by computing
5792 MAC of the message and attaching the MAC to the payload. The
5793 MAC is encrypted. Now, it is clear that this causes some
5794 overhead to the size of the packet but rationale for this is that
5795 now the receiver can verify whether the channel message decrypted
5796 correctly and also when private keys are set for the channel the
5797 receiver can decrypt the packet with several keys and check from
5798 the MAC which key decrypted the message correctly.
5800 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5801 lib/silccrypt/silccipher.[ch].
5803 * Added silc_hash_len to return the digest length into the
5804 lib/silcrypt/silchash.[ch].
5806 * Rewrote parts of Silc Channel Payload interface in the
5807 lib/silccore/silcchannel.[ch]. The encode function now also
5808 encrypts the packet and parse function decrypts it.
5810 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Fixed a minor formatting bug in the SKE's key material processing.
5813 It actually might have processed the keys wrong way resulting
5816 * Redefined the mandatory HMAC algorithms and added new algorithms.
5817 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5818 and hmac-md5 truncated to 96 bits. The mandatory is now
5819 hmac-sha1-96. Rest are optional (including the one that used
5820 to be mandatory). Rationale for this is that the truncated HMAC
5821 length is sufficient from security point of view and can actually
5822 make the attack against the HMAC harder. Also, the truncated
5823 HMAC causes less overhead to the packets. See the RFC2104 for
5826 * Added new [hmac] configuration section. The SKE used to use
5827 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5828 is of course wrong. The official names that must be proposed in
5829 the SKE are the ones defined in the protocol specification
5830 (hmac-sha1-96 for example). The user can configure any hmac
5831 using any hash function configured in the [hash] section. At
5832 least, the mandatory must be configured.
5834 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5836 * Added HMAC list to the SKE proposal list. It has now both
5837 hash algorithm list and HMAC list. This makes the protocol
5838 incompatible with previous versions. The SKE now seems to work
5839 the way it is supposed to work, for the first time actually.
5841 * Defined plain Hash algorithms to the protocol specification.
5844 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5846 * Implemented support for key agreement packets into the server.
5847 Added functions silc_server_key_agreement and
5848 silc_server_send_key_agreement. Other than these functions,
5849 server has nothing to do with this packet.
5851 * Added support for private message key packets into the server.
5852 Added functions silc_server_private_message_key and
5853 silc_server_send_private_message_key.
5857 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5858 called in the protocol's final callback instead in the END
5859 protocol state. This makes a little more sense and in the same
5860 time in client we can use the same protocol routines for normal
5861 key exchange and to key agreement packet handling as well.
5863 * Added to both client's and server's KE protocol context the
5864 SilcSKEKeyMaterial pointer to save the key material. We will
5865 bring the key material to the protocol's final callback by doing
5866 this. The final callback must free the key material.
5868 * Added SKE's packet_send callback into client's KE protocol
5869 context so that the caller can choose what packet sending function
5870 is used. This way we can use different packet sending when
5871 doing normal SKE when doing key agreement packet handling (in
5872 the key agreement packet handling we do not want to encrypt
5875 * Implemented the responder side of the key agreement routines
5876 in the client. The client can now bind to specified port and
5877 accept incoming key negotiation. The key material is passed
5878 to the application after the protocol is over.
5880 * Implemented the processing of incoming Key Agreement packet
5881 in the client. Added function silc_client_key_agreement to
5884 * Implemented the intiator side of the key agreement routines
5885 in the client. The client can now initiate key agreement with
5886 another remote client. The key material is passed to the
5887 application after the protocol is over.
5889 * Created client_keyagr.c to include all the key agreement
5892 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5893 SILC_TASK_CALLBACK except that it is not static.
5895 * Created client_notify.c and moved the Notify packet handling
5896 from the client.[ch] into that file.
5898 * Created client_prvmsg.c and moved all private message and
5899 private message key routines from the client.[ch] into that file.
5901 * Create client_channel.c and moved all channel message and
5902 channel private key routines from the client.[ch] into that file.
5904 * Changed silc_client_get_client_by_id_resolve to resolve with
5905 WHOIS command instead of IDENTIFY command, in the file
5906 lib/silclient/idlist.c.
5908 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * Implemented the SKE's responder side to the Client library.
5912 * When FAILURE is received to the protocol do not trust it
5913 blindly. Register a timeout to wait whether the remote closes
5914 the connection as it should do it, only after that process the
5915 actual failure. This was changed to both client and server.
5917 * Added client_internal.h to include some of the structures
5918 there instead of client.h in lib/silcclient/.
5920 * Added function silc_task_unregister_by_callback to unregister
5921 timeouts by the callback function.
5923 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Some "Incomplete WHOIS info" errors has been appearing on the
5926 log files. Took away the entry->userinfo check from WHOIS
5927 reply sending. The entry->userinfo is now " " if client did not
5928 provide one. I thought this was fixed earlier but something
5929 is wrong still. Let's see if the error still appears.
5931 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Fixed a minor bug in the login when the channel key is
5934 re-generated in the server. It used to generate the key in
5935 wrong order and thus caused problems in the channel traffic.
5937 * Fixed a minor bug in channel key distsribution after
5938 KICK command. The key was not sent to the router even though
5941 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5943 * Added silc_ske_process_key_material_data as generic routine
5944 to process any key material as the SILC protocol dictates. The
5945 function is used by the actual SKE library but can be used by
5946 applications as well. This relates to the private message keys
5947 and the channel private keys since they must be processed the
5948 same way the normal SILC session keys. The protocol dictates
5949 this. Affected files: lib/silcske/silcske.[ch].
5951 Added also silc_ske_free_key_material to free the
5952 SilcSKEKeyMaterial structure.
5954 * Defined silc_cipher_set_key function to set the key for
5955 cipher without using the object's method function. The affected
5956 files: lib/silccrypt/silccipher.[ch].
5958 * Implemented silc silc_client_add_private_message_key,
5959 silc_client_add_private_message_key_ske,
5960 silc_client_del_private_message_key,
5961 silc_client_list_private_message_keys and
5962 silc_client_free_private_message_keys functions in the
5965 Added functions silc_client_send_private_message_key to send
5966 the Private Message Key payload and silc_client_private_message_key
5967 to handle incoming Private Message Key payload.
5969 * Added Cipher field to the Private Message Key payload to set
5970 the cipher to be used. If ignored, the default cipher defined
5971 in the SILC protocol (aes-256-cbc) is used.
5973 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5975 * Removed lib/silcclient/ops.h file.
5977 Redefined parts of the SILC Client Library API. Created new
5978 file silcapi.h that deprecates the ops.h file and defines the
5979 published Client Library API. Defined also private message key
5980 API and channel private key API into the file.
5982 This is the file that the application must include from the
5983 SILC Client Library. Other files need not be included by
5984 the application anymore.
5986 * Added new key_agreement client operation callback and also
5987 defined the Key Agreement library API for the application.
5989 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5992 is used by clients to request key negotiation between another
5993 client in the SILC network. If the negotiation is started it
5994 is performed using the SKE protocol. The result of the
5995 negotiation, the secret key material, can be used for example
5996 as private message key.
5998 Implemented the Key Agreement payload into the files
5999 lib/silccore/silauth.[ch].
6001 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6003 * Redefined ciphers for the SILC protocol. Added some new ciphers
6004 and defined the key lengths for the algorithms. Changed the
6005 code accordingly. The default key length is now 256 bits.
6007 * Fixed SKE key distribution function silc_ske_process_key_material
6008 when the key length is more than 128 bits. The default key
6009 length in SILC is now 256 bits.
6011 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6012 to indicate unsupported algorithm.
6014 * Renamed rijndael.c to aes.c and all functions as well.
6016 * Fixed a long standing channel key setting bug in client library.
6017 Weird that it has never surfaced before.
6019 * Fixed bug in channel deletion. If the entire channel is removed
6020 then it must also delete the references of the channel entry
6021 from the client's channel list as the client's channel entry and
6022 the channel's client entry share same memory.
6024 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Implemented CONNECT and SHUTDOWN commands in the client.
6028 * Implemented CLOSE command to the client.
6030 * Added the function silc_idlist_find_server_by_name into the
6031 files silcd/idlist.[ch].
6033 Added the function silc_idlist_find_server_by_conn into the
6034 files silcd/idlist.[ch].
6036 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6038 * DIE command was renamed to SHUTDOWN. Updated the both code
6041 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6042 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6044 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6047 * Added function silc_server_create_connection function to create
6048 connection to remote router. My server implementation actually
6049 does not allow router to connect to normal server (it expects
6050 that normal server always initiates the connection to the router)
6051 so the CONNECT command is only good for connecting to another
6054 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6056 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6057 or some other client was kicked from the channel.
6059 Implemented the handling of the notify type to both client
6062 Implemented silc_server_send_notify_kicked to send the KICKED
6063 notify. It is used to send it to the server's primary router.
6065 * Implemented the KICK command into server and client.
6067 * Added `query' argument to the silc_idlist_get_client function
6068 to indicate whether to query the client from server or not if
6071 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6072 to indicate that the client is not channel founder.
6076 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Removed the rng context from SilcPacketContext structure and
6079 changed that the packet routine uses the Global RNG API.
6081 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Added support for quit message that client can "leave" on the
6084 channel when it quits the SILC. It is ditributed inside the
6085 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6087 Added silc_server_free_client_data that will take the
6088 signoff message as argument.
6090 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6092 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Updated parts of the protocol specification to keep it up
6097 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6099 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6100 payloads in one packet.
6102 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6103 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6104 use now the new List flag.
6106 * Also deprecated the following packet types: REPLACE_ID,
6107 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6109 * Added list support for Notify packet in server.
6111 * Added silc_server_send_notify_channel_change to send the
6112 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6113 the silc_server_send_replace_id.
6115 * Added silc_server_send_notify_nick_change to send the
6116 NICK_CHANGE notify type. Deprecates the function
6117 silc_server_send_replace_id.
6119 * Added silc_server_send_notify_join to send the JOIN notify type.
6120 Deprecates the function silc_server_send_new_channel_user.
6122 * Added silc_server_send_notify_leave to send LEAVE notify type.
6123 Deprecates the function silc_server_send_remove_channel_user.
6125 * Added silc_server_send_notify_cmode and
6126 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6127 types. Deprecates the silc_server_send_set_mode function.
6129 * Added SERVER_SIGNOFF notify type to indicate that server has
6130 quit. This means that all clients on the channel from that
6131 server will drop. This can be also used when netsplit happens.
6133 Deprecated REMOVE_ID packet type since it is not needed anymore
6136 Added silc_server_send_notify_server_signoff to send the
6137 SERVER_SIGNOFF notify type. Deprecates the function
6138 silc_server_send_remove_id.
6140 Added also silc_server_send_notify_signoff to send the
6141 SIGNOFF notify type.
6143 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6144 SILC protocol from this day on. Changed the protocol
6145 specification as well.
6147 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6148 notify type. It is used between routers to notify about
6149 topic changes on a channel.
6151 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6154 * Partly updated the protocol specification to comply with the
6155 changes now made. It is still though a bit outdated.
6157 * The JOIN notify type now takes one extra argument <Channel ID>.
6158 The packet used to be destined to the channel but now the
6159 JOIN type may be sent as list thus it is impossible to
6160 destine it to any specific channel. By adding this argument
6161 it is again possible.
6163 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6165 * Added CREDITS file. The CHANGES and CREDITS file will appear
6166 in the distribution as well.
6168 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6170 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6171 types in the server's silcd/packet_receive.c.
6173 * Implemented CMODE and CUMODE to work in router environment.
6175 * Fixed minor encoding and decoding buglet from the
6176 lib/silccore/silcmode.c.
6178 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6181 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6183 * Changed all SilcConfigServer* and silc_config_server* to
6184 SilcServerConfig* and silc_server_config*, respectively.
6187 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Associated the ID (client or server ID) to the Authentication
6190 Payload to avoid any possibility of forging. Updated the
6191 protocol specification and the code accordingly.
6193 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * The RSA key length is now save to the RsaKey context in the
6196 key generation process in lib/silccrypt/rsa.c. The key length
6197 is now used to figure out the maximum size of the block allowed
6198 to be encrypted/signed.
6200 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6201 is equivalent to the silc_mp_mp2bin but does not allocate any
6204 * Changed silc_mp_mp2bin API to take length argument. If it is
6205 non-zero then the buffer is allocated that large. If zero, then
6206 the size is approximated using silc_mp_sizeinbase, which however
6209 * Created Global RNG API which is global RNG that application can
6210 initialize. After initializing, any routine anywhere in the
6211 code (including library) can use RNG without allocating a new
6212 RNG object. This was done to allow this sort of use of the
6213 RNG in code that has no chance to allocate RNG object. All
6214 applications currently allocate this and many routines in the
6215 library use this. Affected file lib/silccrypt/silcrng.[ch].
6217 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6218 it to use the Global RNG API.
6220 * Defined Authentication Payload into protocol specification that
6221 is used during SILC session to authenticate entities. It is
6222 used for example by client to authenticate itself to the server
6223 to obtain server operator privileges.
6225 Implemented this payload into the lib/silccore/silcauth.[ch].
6226 Implemented also routines for public key based authentication
6227 as the new protocol specification dictates.
6229 Moved definitions of different authentication methods from
6230 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6232 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6233 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6234 silc_pkcs_verify_with_hash functions into the file
6235 lib/silccrypt/silcpkcs.[ch].
6237 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * The client entry's userinfo pointer must be always valid.
6240 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6241 will fail since it requires the userinfo. Now, the userinfo
6242 is allocated as "" if actual userinfo does not exist. Actually,
6243 it must exist and it is totally Ok to drop client connections
6244 that does not announce the userinfo. However, we will make
6245 this workaround for now.
6247 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6248 to return the remote port by socket.
6250 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6252 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6253 SILC_SERVER_PENDING_EXEC and added an new macro
6254 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6255 data or when error occurs while processing the pending command.
6257 Added new argument `destructor' into silc_server_command_pending
6258 and to the SilcServerCommandPending object. This destructor is
6259 now called after calling the pending callback or if error occurs
6260 immediately. If error occurs the actual pending callback won't
6261 be called at all - only the destructor. The destructor may be
6262 NULL if destructor is not needed.
6264 All this applies for client library code as well. Similar
6265 changes were made there as well for the pending commands.
6267 In the client, the application must now allocate the
6268 SilcClientCommandContext with the silc_client_command_alloc
6271 * Added reference counter to the SilcServerCommandContext. Added
6272 function silc_server_command_alloc and silc_server_command_dup
6275 Same type of functions added to the client library for the same
6278 * Removed the cmd_ident from IDListData away since it is now
6279 global for all connections. It is the command identifier used
6280 in command sending and with pending commands. The affected file
6283 * Added reference counter to the SilcSocketConnection objecet to
6284 indicate the usage count of the object. The object won't be
6285 freed untill the reference counter hits zero. Currently only
6286 server uses this, and client ignores it. The client must be
6287 set to use this too later. The affected files are
6288 lib/silccore/silcsockconn.[ch]. Added also the function
6289 silc_socket_dup to increase the reference counter.
6291 This was mainly added because it is possible that the socket
6292 is removed underneath of pending command or other async
6293 operation. Now it won't be free'd and proper DISCONNECTING
6294 flags, etc. can be set to avoid sending data to connection that
6295 is not valid anymore.
6297 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6298 the connection. After that it sets SILC_SET_DISCONNECTED.
6299 It is, however, possible that the socket data is not still freed.
6300 The silc_server_packet_process now checks that data is not
6301 read or written to connection that is DISCONNECTED. The socket
6302 get's freed when the reference counter hits zero.
6304 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6306 * Changed the client operation API: channel_message operation's
6307 `sender' is now the client entry of the sender, not the nickname
6308 and the `channel' is the channel entry, not the channel name.
6310 In the private_message operation the `sender' is now also the
6311 client entry of the sender not the nickname.
6313 Affected file is lib/silcclient/ops.h and all applications
6314 using the client operations.
6316 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6318 * Moved the calling of ops->connect() from connect_to_server_final
6319 into receive_new_id functin since that is the point when the
6320 client is actually allowed to send traffic to network. The
6321 affected file is lib/silcclient/client.c.
6323 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6325 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6326 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6327 (if needs broadcasting) instead of broadcasting the packets one
6328 by one which would make a burst in the network traffic.
6330 * Added `broadcast' argument to the functions in silcd/server.[ch]
6331 silc_server_create_new_channel[_with_id] to indicate whether
6332 to send New Channel packet to primary router.
6334 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * Added new function into the silcd/server.[ch] files:
6337 silc_server_create_new_channel_with_id to create new channel with
6338 already existing Channel ID.
6340 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6341 lib/silccore/silcpacket.h. This packet is used t send list of
6342 Set Mode payloads inside one packet. Server uses this to set
6343 the modes for the channels and clients on those channels, that it
6344 announced to the router when it connected to it. The protocol
6345 specification has been updated accordingly.
6347 * The silc_server_new_channel did not handle the packet coming
6348 from normal server as it normally does not send that. However,
6349 when it announces its channels it does send it. Implemented
6350 the support for that.
6352 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6353 into the file lib/silccore/id.h.
6355 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6357 * Fixed memory leaks in the functions silc_idlist_del_client,
6358 silc_idlist_del_channel and silc_idlist_del_server in the file
6359 silcd/idlist.c. All of those leaked like a sieve.
6361 * Fixed some small memory leaks in the client's function
6362 silc_client_notify_by_server.
6364 * Added functions into silcd/server.c: silc_server_announce_clients,
6365 silc_server_announce_channels and silc_server_announce_server.
6366 These functions are used by normal and router server to announce
6367 to its primary router about clients, channels and servers (when
6368 router) that we own. This is done after we've connected to the
6371 These functions effectively implements the following packet types:
6372 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6373 and SILC_PACKET_NEW_ID_LIST.
6375 * Added new functions into the silcd/packet_receive.[ch]:
6376 silc_server_new_id_list, silc_server_new_channel_list and
6377 silc_server_new_channel_user_list to handle the incoming
6378 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6380 * Added support of changing Channel ID in the function
6381 silc_server_replace_id. If the server that announces a channel
6382 to the router already exists in the router (with same name but
6383 with different Channel ID), router is responsible to send
6384 Replace ID packet to the server and force the server to change
6385 the Channel ID to the one router has.
6387 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6388 client that the Channel ID has been changed by the router. The
6389 normal server sends this to the client. Client must start using
6390 the new Channel ID as the channel's ID.
6392 Implemented handling of this new type into lib/silcclient/client.c
6393 into the function silc_client_notify_by_server.
6395 * Added new function silc_idlist_replace_channel_id into the files
6396 silcd/idlist.[ch] to replace the Channel ID.
6398 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Call silc_server_command_identify_check always when processing
6401 the IDENTIFY command in silcd/command.c
6403 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6405 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6406 send keepalive packets. The packet can be sent by clients,
6407 servers and routers.
6409 Added function silc_socket_set_heartbeat into the file
6410 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6411 If not set, the heartbeat is not performed. The actual
6412 heartbeat is implemented in the low level socket connection
6413 library. However, application is responsible of actually
6416 Added silc_server_send_heartbeat to send the actual heartbeat
6417 packet into silcd/packet_send.[ch]. Server now performs
6418 keepalive with all connections.
6420 * Added silc_task_get_first function into lib/silcutil/silctask.c
6421 to return the timeout task with shortest timeout. There was a bug
6422 in task unregistration that caused problems. TODO has been
6423 updated to include that task system must be rewritten.
6425 * The client library will now resolve the client information when
6426 receiving JOIN notify from server for client that we know but
6427 have incomplete information.
6429 * Rewrote parts of silc_server_remove_from_channels and
6430 silc_server_remove_from_one_channel as they did not remove the
6431 channel in some circumstances even though they should've.
6433 * Encryption problem encountered in server:
6435 The LEAVE command used to send the Channel Key packet to the
6436 router immediately after generating it. However, the code
6437 had earlier sent Remove Channel user packet but not immediately,
6438 ie. it was put to queue. The order of packets in the router
6439 was that Channel Key packet was first and Remove Channel User
6440 packet was second, even though they were encrypted in the
6441 reverse order. For this reason, MAC check failed. Now, this
6442 is fixed by not sending the Channel Key packet immediately but
6443 putting it to queue. However, this is more fundamental problem:
6444 packets that are in queue should actually not be encrypted
6445 because packets that are sent immediately gets encrypted
6446 actually with wrong IV (and thus MAC check fails). So, packets
6447 that are in queue should be encrypted when they are sent to
6448 the wire and not when they put to the queue.
6450 However, the problem is that the current system has not been
6451 designed to work that way. Instead, the packet is encrypted
6452 as soon as possible and left to the queue. The queue is then
6453 just purged into wire. There won't be any fixes for this
6454 any time soon. So, the current semantic for packet sending
6457 o If you send packet to remote host and do not force the send
6458 (the packet will be in queue) then all subsequent packets to the
6459 same remote host must also be put to the queue. Only after the
6460 queue has been purged is it safe again to force the packet
6463 o If you send all packets immediately then it safe to send
6464 any of subsequent packets through the queue, however, after
6465 the first packet is put to queue then any subsequent packets
6466 must also be put to the queue.
6468 Follow these rules and everything works fine.
6470 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6472 * Added new function silc_server_remove_clients_by_server to
6473 remove all client entries from ID list when the server connection
6474 is lost. In this case it is also important to invalidate all
6475 client entires as they hold the invalid server entry. This
6476 fixes fatal bug when server has lost connection and will reconnect
6479 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6481 * Made some sanity checks to silc_server_daemonise like to check
6482 whether the requested user and group actually exists.
6484 * Added sanity check to SKE's silc_ske_responder_finish to check
6485 that the public and private key actually is valid.
6487 * Invalidate the client's nickname when receiving Replace ID
6488 packet and the Client ID is being replaced. This means that the
6489 server will query the nickname if someone needs it (client)
6492 * Sort the ID Cache in client library when the ID Cache data
6493 has changed (needs sorting).
6495 * Do not allow for SILC client to create several connections to
6496 several servers. The client does not support windows right now
6497 and generating multiple connections causes weird behaviour.
6499 Irssi-silc client does support windows and can handle several
6500 connections without problems, see: www.irssi.org and SILC plugin.
6502 * Fixed some places where client was added to the IDList. The
6503 rule of thumb is following (in order to get everything right):
6504 If the client is directly connected local client then the
6505 `connection' argument must be set and `router' argument must be
6506 NULL to silc_idlist_add_client function. If the client is not
6507 directly connected client then the `router' argument must
6508 bet set and the `connection' argument must be NULL to the
6509 silc_idlist_add_client function.
6511 * The funtion silc_server_packet_send_local_channel actually did
6512 not check whether the client was locally connected or not. It
6513 does that now. Fixed a bug related to LEAVE command.
6515 * Fixed Remove Channel User payload parsing bug in server's
6516 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6518 * The server's silc_server_save_channel_key now checks also the
6519 global ID list for the channel as it might not be in the local
6520 list. Fixed a bug related to LEAVE command.
6522 * Is this the end of the [<unknown>] buglet that has been lurking
6523 around for a long time? A little for loop fix in server's
6524 silc_server_command_whois_parse that is used by both IDENTIFY
6525 and WHOIS command. At least, this was a clear bug and a cause
6526 of one type of [<unknown>] buglet.
6528 * WHOIS and IDENTIFY commands call the function
6529 silc_server_command_[whois/identify]_check function even if
6530 we are not router server.
6532 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6534 * Added --with-gmp configuration option. If set the GMP
6535 is always compiled in the SILC source tree. If not set then
6536 it is checked whether the system has the GMP3 installed. If
6537 it has then the GMP won't be compiled (the system's headers
6538 and library is used), if it doesn't have it then the GMP is
6539 compiled in the SILC source tree.
6541 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Changed RSA private exponent generation to what PKCS #1
6544 suggests. We try to find the smallest possible d by doing
6545 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6546 not security fix but optimization.
6548 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * Added new config entry [Identity] to fork the server and run
6551 it as specific user and group. A patch from Bostik.
6553 * Imported Dotconf configuration library into lib/dotconf.
6554 This will be used to create the SILC configuration files later.
6555 It will appear in the distsribution after this commit.
6557 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6559 * A big code auditing weekend happening. Auditing code for
6560 obvious mistakes, bugs and errors. Also, removing any code
6563 Removed files for being obsolete:
6565 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6566 inline in the file lib/silcutil/silcbuffer.h)
6568 o lib/silcutil/silcbufutil.c (the header has inline versions)
6570 Changed code to fix possible error conditions:
6572 o The buffer formatting routines now check that the destination
6573 buffer really has enough space to add the data. This applies for
6574 both buffer formatting and unformatting
6575 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6576 unformatting was changed to accomodate following rules:
6577 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6578 sent to the function while XXX_*STRING will not allocate or copy
6579 the data into the buffer. Instead it sets the pointer from the
6580 buffer into the pointer sent as argument (XXX_*STRING used to
6581 require that the pointer must be allocated already). This change
6582 makes this whole thing a bit more consistent and more optimized
6583 (note that the data returned in the unformatting with XXX_*STRING
6584 must not be freed now). The routines return now -1 on error.
6586 o Tried to find all code that use buffer_format and buffer_unformat
6587 and added return value checking to prevent formatting and
6588 especially unformatting errors and possible subsequent fatal
6591 o Changed ske->x and ske->KEY to mallocated pointers in
6592 lib/silcske/silcske.h. Fixed possible data and memory leak.
6594 o Added return value checking to all *_parse* functions. Fixed
6595 many memory leaks as well.
6597 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6598 so that buffer overflows would not happen. All code now also
6599 checks the return value as it can fail.
6601 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6603 * Added reconnection support to server if the normal server looses
6604 its connection to the router (for example if router is rebooted).
6605 The server performs normal reconnection strategy implemented
6606 to the server. Affected file silcd/server.c.
6608 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6610 * Added new packet type SILC_PACKET_SET_MODE that is used to
6611 distribute the information about changed modes (for clients,
6612 channels and clients channel modes) to all routers in the
6613 network. Updated the protocol specification accordingly.
6615 Added functions into silcd/packet_send.c and
6616 silcd/packet_receive.c: silc_server_send_set_mode,
6617 silc_server_set_mode.
6619 Added new files silcmode.[ch] into lib/silccore that implements
6620 the encoding and decoding of Set Mode Payload. Added new type
6621 SilcSetModePayload. Moved the definitions of different modes
6622 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6624 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6626 * Oops, a little mistake in server's connection authentication
6627 protocol. The protocol is not ended with FAILURE but with
6628 SUCCESS if the authentication is Ok. :) Affected file is
6631 * Implemented NICK_CHANGE notify handling in server in the file
6632 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6633 the local clients on the channel. After the changing nickname
6634 in router environment snhould work and the [<unknown>] nickname
6635 should appear no more.
6637 The silc_server_replace_id function that receives the Replace ID
6638 payload now sends the NICK_CHANGE notify type also in the file
6639 silcd/packet_receive.c
6641 * Changed WHOIS and IDENTIFY command to support the maximum amount
6642 of arguments defined in protocol specs (3328 arguments). This
6643 fixed a bug that caused problems when there were more than three
6646 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6648 * Added extra parameter, command identifier, to the
6649 silc_client_send_command so that explicit command identifier
6652 Changed that ID list routines uses specific command identifier
6653 when sending WHOIS/IDENTIFY requests to the server so that they
6654 can be identified when the reply comes back.
6656 Affected files lib/silcclient/command.[ch],
6657 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6659 * Added `sender' argument to silc_server_packet_send_to_channel
6660 to indicaet the sender who originally sent the packet to us
6661 that we are now re-sending. Ignored if NULL. Affected file
6662 silcd/packet_send.[ch].
6664 * Added some server statistics support in silcd/server_internal.h
6665 SilcServerStatistics structure and around the server code. Also
6666 send some nice statistics information when client is connecting
6669 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Fixed channel ID decoding in server's JOIN command reply in
6672 silcd/command_reply.c
6674 * Fixed braodcasting of replace ID payload to not to send it if
6675 we are standalone server in silcd/packet_receive.c.
6677 * Fixed all channel message sending routines to not to send
6678 packets to clients that has router set, since they are routed
6679 separately in the same function earlier. Affects file
6680 silcd/packet_send.c and all channel packet sending functions.
6682 * In USERS reply, res_argv[i] are not allocated, the table
6683 is allocated. Thus changed that free the table, not its
6686 * In server's whois_check and identify_check if the client is
6687 locally connected do not send any WHOIS commands - they are not
6690 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Fixed some minor bugs in client when sending WHOIS command. The
6693 arguments was in wrong order.
6695 * Removed statis function add_to_channel from server in
6696 silcd/command.c that was previously used with the joining but
6699 * Tested USERS command in router environment successfully with two
6700 routers, two servers and two clients.
6702 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6704 * Reorganized the USERS command and command reply in client library
6705 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6706 When the command is given by user we register a pending command
6707 callback that will reprocess the command after the reply has been
6708 received from the server. When reprocessing the packet we then
6709 display the information. Thus, the USERS information is displayed
6710 now in the command callback instead of in the command reply
6711 callback. The processing of the command is same as previously
6712 when server has sent the command reply in the JOINing process.
6714 * Added to USERS command in silcd/command_reply.c to join the client,
6715 we didn't use to know about, to the channel after we've created
6716 a client entry for it. Also, for clienet we did know already still
6717 check whether it is on the channel or not and add it if not.
6719 * Removed silc_server_command_join_notify as the function and its
6722 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6724 * Changed the client's pending command handling to the same as the
6725 server's pending command handling. It is also now possible to
6726 execute command reply functions from other command reply
6727 function as the function callbacks for commands and command
6728 replies are one and same. The pending commands are not static
6729 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6730 in client connection context. Thus, pending commands are server
6731 connection specific as it is convenient.
6733 Changed the function silc_client_command_pending and
6734 silc_client_command_pending_del and added new function
6735 silc_client_command_pending_check. Removed the
6736 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6739 * Added cmd_ident, current command identifier, to the client
6740 connection context in lib/silcclient/client.h to keep track on
6741 command identifiers used in command sending. Client's command reply
6742 function handling now supports the mandatory command identifiers.
6744 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6745 funtions in client to fully support pending command callbacks.
6747 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6748 as one of the arguments to the application in the command reply
6751 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6752 before first releasing SILC but came back. Now it is removed again
6753 and should come back nomore. The FORWARDED flag was used only
6754 by the JOINing procedure by forwarding the command packet to router.
6755 Now, the JOINing procedure has been changed to more generic (due
6756 to various router environment issues) and FORWARDED is not needed
6757 anymore for anything. The protocol specification is yet to be
6760 Now, removed silc_server_packet_forward from server and the flag
6761 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6763 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6765 * Renamed NAMES command to USERS command. The NAMES was named that
6766 due to historical reasons. Now it is renamed. Also, rewrote
6767 parts of the USERS command. The nickname list is not sent anymore
6768 by the server. Only Client ID and mode lists are sent in the USERS
6769 command. Changed this also to the protocol specification.
6771 The client now resolves the names and stuff after it receives
6772 the USERS list from the server when joining to the channel.
6774 * WHOIS and IDENTIFY commands has been changed to support multiple
6775 Client ID's per command. One can now search for multiple users
6776 in the network by sending only one WHOIS or IDENTIFY command.
6777 Changed the code and the protocol specifications.
6779 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6780 uses silc_server_command_whois_parse to parse the request. */
6782 * If normal server, do not parse the WHOIS and IDENTIFY requests
6783 before sending it to the router. Saves some time.
6785 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6787 * Fixed JOIN command on client library. Wrong number of arguments
6788 used to crash the client.
6790 * Added silc_server_channel_has_global function to check whether
6791 channel has global users or not.
6793 * Added silc_server_channel_has_local function to check whether channel
6794 has locally connected clients on the channel.
6796 * The silc_server_remove_from_one_channel now checks whether the
6797 channel has global users or not after given client was removed from
6798 the channel. It also checks whether the channel has local clients
6799 on the channel anymore. If it does not have then the channel entry
6800 is removed as it is not needed anymore.
6802 * The silc_server_notify now checks on JOIN notify whether the joining
6803 client is one of locally connected or global. If it is global then
6804 the channel has now global users on the channel and that is marked
6805 to the channel entry. Also, it now saves the global client to
6806 global list who is joining and JOINs it to the channel. This is
6807 for normal server, that is.
6809 Changed silc_server_send_notify_on_channel,
6810 silc_server_packet_relay_to_channel and
6811 silc_server_packet_send_to_channel check if we are normal server
6812 and client has router set (ie. global client) do not send the
6813 message to that client, as it is already routed to our router.
6815 * Implemented LEAVE notify type handling in silc_server_notify
6818 * Tested LEAVE command in router environment successfully. Tested
6819 with two routers, two servers and two clients.
6823 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6825 * Implemented SIGNOFF notify type handling in silc_server_notify
6828 * silc_server_remove_id now removes the client entry from all channels
6829 it has joined and thusly sends SIGNOFF notify type.
6831 * Rewrote the NAMES list generation in server by removing two excess
6832 loops. The lists are created now inside one loop.
6834 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * silc_server_remove_channel_user checks now also global list
6837 for channel and client.
6839 * silc_server_new_channel_user checks now both local and global
6840 list for channel and client. Fixed a bug in client id decoding.
6841 Used to decode wrong buffer.
6843 * silc_server_channel_message checks now both local and global
6844 list for channel entry.
6846 * Tested channel joining (hence JOIN) in router environment
6847 successfully. Tested with two routers, two servers and two
6850 * Tested channel message sending in router environment successfully.
6852 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6854 * Added silc_server_save_channel_key into server.[ch] to save the
6855 received channel key in Channel Key payload processing. It is
6856 also used in JOIN command reply handling.
6858 Equivalent function silc_client_save_channel_key added into
6859 client.[ch] into client library.
6861 * Changed JOIN command reply to send information whether the channel
6862 was created or not (is existing already) and the channel key
6863 payload. Changed protocol specs accordingly.
6865 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6866 the request was sent by ID and not by nickname. Crashed on
6869 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6871 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6872 now correctly save the received data.
6874 * silc_server_free_sock_user_data now notifies routers in the
6875 network about entities leaving the network.
6877 At the same time implemented functions silc_server_remove_id
6878 and silc_server_send_remove_id to receive and send REMOVE_ID
6879 packets. The packet is used to notify routers in the network
6880 about leaving entities. The ID removed will become invalid in
6883 * Added function silc_idlist_del_server into server. Removes and
6884 free's server entry from ID list.
6886 * silc_server_private_message function now checks, if we are router,
6887 that the destination ID really is valid ID, naturally.
6889 * In router when NEW_ID packet is received (for new client) the
6890 hash of the Client ID is saved in the ID Cache but the
6891 client->nickname is set to NULL, instead of putting the hash
6894 IDENTIFY command now also checks that client->nickname must be
6895 valid. If it is not if will request the data from the server who
6896 owns the client. Added new function
6897 silc_server_command_identify_check.
6899 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6900 to set the command to already allocated Command Payload.
6902 * Tested private message sending in router environment with two
6903 routers, two servers and two clients. Fixed minor bugs and now
6906 * Fixed segfault from client's NAMES command. Used to crash if
6909 * Forwarded packets must not be routed even if it is not destined
6910 to the receiver. Changed server code comply with this.
6912 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Added `require_reverse_mapping' boolean value to ServerParams
6915 structure. If TRUE (not default) the server will require that
6916 the connecting host has fully qualified domain name.
6918 If the reverse mapping is not required and hostname could not be
6919 found the IP address is used as hostname.
6921 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6923 * Implemented version string checking to both client and server.
6924 The check is incomplete currently due to the abnormal version
6925 strings used in development version of SILC.
6927 * Changed all command functions in server to use the new
6930 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6932 * Changed char *data to unsigned char *data in ID Cache system to
6933 support binary data as ID Cache data. Changed code to support
6934 binary data in lib/silccore/idcache.c.
6936 * Renamed silc_server_packet_relay_command_reply to
6937 silc_server_command_reply as it is normal packet receiving
6938 function. Rewrote the function to accept command replys for
6939 servers and not only for clients.
6941 * Mark remote router always as registered server if we are connecting
6942 to it. Otherwise, commands sent by the router to us are ignored.
6944 * All ID List find routines now returns the ID Cache Entry pointer
6945 as well if requested.
6947 * WHOIS command works now in router environment, tested with two
6948 routers, two servers and two clients.
6950 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6951 in router environment (as it is almost equivalent to WHOIS) but
6952 hasn't been tested thoroughly. Added new functions:
6954 silc_server_command_identify_parse
6955 silc_server_command_identify_send_reply
6956 silc_server_command_identify_from_client
6957 silc_server_command_identify_from_server
6959 * Disabled route cache adding because adding two different ID's with
6960 same IP replaces the old cache entry thus giving wrong route.
6961 The entry->router->connection is always the fastest route anyway
6962 so route cache may not be needed. Of course, new routes maybe
6963 established after receiving the ID when the entry->router->connection
6964 might not be anymore the most optimal.
6966 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6968 * Add route cache for received ID for fast routing.
6970 * Added silc_server_packet_route to route received packet on router
6971 that is not destined to us.
6973 * Renamed silc_server_get_route to silc_server_route_get.
6975 * Added id_string and id_string_len fields into SilcServer to
6976 include encoded ServerID for fast comparing without excess
6977 encoding of the ID's.
6979 * Cleaned up WHOIS command on server side. Added following static
6982 silc_server_command_whois_parse
6983 silc_server_command_whois_check
6984 silc_server_command_whois_send_reply
6985 silc_server_command_whois_from_client
6986 silc_server_command_whois_from_server
6988 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6989 arguments in command replies. All command functions should be
6990 updated to use this macro.
6992 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6994 * Minor typo fixes on command reply handling on server.
6996 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6998 * Added silc_server_command_add_to_channel internal routine to add
6999 the client to the channel after router has created the channel and
7000 sent command reply to the server.
7002 * Added generic silc_server_send_command to send any command from
7005 * Use static buffer with ID rendering instead of duplicating data.
7007 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7009 * Fixed a channel user mode bug when joining to a channel server gave
7010 everybody channel founder rights, oops.
7012 * We mark ourselves as the router of the incoming server connection
7013 if we are router ourselves. This way we can check in some packet
7014 sending functions whether it is locally connected server. For
7015 incoming router connections we put NULL.
7017 * For router sending packets locally means now always sending the
7018 packet cell wide; to local clients and local servers. For normal
7019 server sending packet locally means sending it to only local
7022 * Fixed the JOIN command to really work in router environment. If the
7023 channel is created it is always created by the router. Router is
7024 also responsible of making the initial joining to the channel,
7025 sending JOIN notify to the sending server and distributing
7026 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7027 does not exist server doesn't do anything else but forward the
7028 command to the router which performs everything.
7030 * Added silc_server_send_channel_key function to send the Channel Key
7033 * Added silc_server_create_channel_key to create new channel key. The
7034 channel key is now re-generated everytime someone joins or leaves
7035 a channel, as protocol dictates. Note: channel->key_len is the
7038 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7040 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7041 packet_receive.[ch] to separate packet sending and receiving
7042 routines. The server.[ch] now includes everything else including
7043 actual packet processing (writing and reading data) and other
7046 Renamed silc_server_private_message_send_internal to
7047 silc_server_send_private_message. The routine is still though
7048 used only to relay private messages as server does not send
7049 private messages itself.
7051 Renamed silc_server_new_channel to silc_server_create_new_channel
7052 and added new function sicl_server_new_channel that handles the
7053 incoming New Channel packet. Added also new sending function
7054 silc_server_send_new_channel to send New Channel Payload.
7056 * Added new function silc_server_notify to process incoming notify
7057 packet to the server/router. Server may then relay the notify
7058 to clients if needed.
7060 * Added new function silc_server_new_channel_user to process incoming
7061 New Channel User packet. Router will redistribute the packet and
7062 send JOIN notify to its local clients and locally connected servers
7063 if needed. Normal server will send JOIN notify to its local client
7064 on same channel when received this packet. Added also corresponding
7065 sending function silc_server_send_new_channel_user to sent the
7068 * Added boolean route argument to send_notif_to_channel and
7069 packet_send_to_channel functions to attempt to route the packet
7070 if it is TRUE and send only locally if it is FALSE.
7072 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * silc_server_replace_id now broadcasts the received replace ID
7075 packet if it is not broadcast packet already. The router must
7076 broadcast to inform other routers about changed ID.
7078 * Added backpointer to server's router into SilcServer context in
7079 silcd/server_internal.h.
7081 * Fixed silc_server_packet_broadcast to send correct broadcast
7084 * The channel key is now distributed to the local client as soon
7085 as it is received from the router (in router environment) so that
7086 no other packet may be sent for the channel until client has
7089 * silc_server_remove_channel_user now broadcasts the received
7090 Remove Channel User packet if it is not broadcast packet already.
7091 The router must broadcast to inform other routers about removed
7094 * Added users field into SilcPacketContext that is a reference count
7095 of the context. One can increase the reference count by calling
7096 silc_packet_context_dup which is now changed to just increase the
7097 reference count instead of duplicating the data. The reference
7098 count is decresed by calling silc_packet_context_free that will
7099 free the data after the reference count hits zero.
7101 For now on the packet context and everything allocated into it
7102 (including the raw packet from network) must be freed by calling
7103 the new silc_packet_context_free function. Added also new function
7104 silc_packet_context_alloc that must be used now to allocate the
7105 context. This also means that if a routine is asynchronous from
7106 silc_[client/server]_packet_parse_type the packet context must
7107 be duplicated by calling silc_packet_context_dup. Otherwise it
7108 gets free'd after silc_[client/server]_packet_parse_type returns.
7109 Also, one must remember that if packet is duplicated then its
7110 reference count must be decresed by calling the free function as
7111 many times as it was duplicated.
7113 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7114 from both client and server.
7116 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Made joining to a channel working in router environment.
7120 * Cleaned up JOIN command on server side and create function
7121 silc_server_command_join_channel internal routine to make the
7124 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7126 * Changed silc_command_pending list to SilcDList. Also, added
7127 `ident' field to SilcServerCommandPending structure to identify
7128 the reply and to call correct callback.
7130 Added silc_server_command_pending_check function to replace the
7131 corresnponding macro. The silc_command_pending list is not
7134 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7135 to set identifier to previously allocated Command Payload. It
7136 is used to set identifier for command when resending Command
7139 * Added silc_command_payload_encode_payload to encode Command
7140 Payload buffer from SilcCommandPayload structure.
7142 * Added silc_argument_payload_encode_payload to encode Argument
7143 payload buffer from SilcArgumentPayload structure.
7145 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7147 * Changed WHOIS command to support router connection on server side.
7148 The whois request is always sent to router unless the server is
7149 standalone server. After server has received the reply from the
7150 router will it send the reply to the client.
7152 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7153 broadcast received broadcast packet. The function is used only
7154 by router. The broadcast packet is always sent to the router's
7157 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7158 render given ID to printable string, for log files for example.
7160 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7162 * Made basic router to router connections working. At least they
7163 can now connect to each other but nothing really works the way
7164 they are supposed - yet.
7166 * Added new initiator token to RouterConnection configuration
7167 file in silcd/serverconfig.[ch]. It is used to tell whether we
7168 are the initiator to the remote router or whether we'll expect
7169 the other end to connect.
7171 * Moved registering of listener task to silc_server_init, hence
7172 the server starts listenning as soon as it is run, even if it
7173 does not have connections to other routers. Let's see how well
7176 * Changed default connection retry timeouts for more suitable in
7179 * Removed cipher and such arguments from silc_idlist_add_client
7180 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7181 Added new function silc_idlist_add_data to add the keys and stuff
7184 * Added SilcIDListData structure and added it to SilcClientEntry
7185 and SilcServerEntry as their first field in the structure. This
7186 way we can explicitly cast the ID entries to the SilcIDListData
7187 structure and get common data for the entries. In past, we had
7188 to first check what type of connection it is and then cast it to
7189 correct ID entry type. Now, we can directly cast the opaque
7190 pointer to the SilcIDListData (no matter what ID entry it actually
7191 is) and get the data needed.
7193 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7195 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7196 in some circumstances even if threre were timeout tasks, though not
7197 IO tasks, but tasks anyway. Now fixed.
7199 * Defined SilcServerConnection structure to hold connection specific
7200 stuff about directly connected servers and routers. The definition
7201 is currently in silcd/server_internal.h. I thought about having
7202 a bit more important role fro this struct but for now it is used
7203 only when connecting to other server (or router actually).
7205 * Added connecting retry support in server when connecting to
7206 router(s). The retry feature implement exponential backoff
7207 algorithm. Also, added SilcServerParams structure to hold default
7208 parameters for server. For now, it include these retry settings
7209 and are hard coded. After server is moded to be as Silc Server
7210 Library this structure will be more important.
7212 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7214 * Changed client librarys channel->clients table to SilcList and
7215 changed code accordingly.
7217 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7219 * Changed client's channel table to SilcList and changed code
7220 accordingly. Also changed SilcChannelClientEntry to include back-
7221 pointer to the channel so that client entry can use that structure
7222 as list as well and we have fast cross-reference to the channel.
7223 This change dramatically decreased the complexity of channel
7224 handling with client entry and vice versa (removed one extra
7225 loop when searching for channel entry from many functions).
7227 * Changed server->sim from table to SilcDList and changed code
7230 * NAMES command can now be used from user interface. It will show
7231 the user list on the channel, neatly.
7233 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7234 Code now saves realname of the user if it becomes available.
7236 * Renamed configure.in to configure.in.pre and made ./prepare
7237 script to automatically add correct version string to
7238 configure.in which it creates from configure.in.pre.
7240 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7242 * NAMES command reply now shows users mode with the nickname when
7245 * Moved silc_client_ch[u]mode[_char] functions from
7246 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7247 place sucks, they are utility functions and should be in some
7250 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7252 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7255 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7259 * Added TRQ (efficient deque and list library) into lib/trq. This is
7260 a very good list library that is currently used in the SILC. Defined
7261 SilcList API over the library because I didn't like the API very
7262 much. See lib/trq/silclist.h for the API and examples of how to
7263 use the API. Fixed various places in the code to use the new
7264 SilcList API. The SilcList is meant for lists that has a structure
7265 already defined as a list. It is not suitable to add just some
7266 context to the list (in TRQ, the context is the list actually).
7268 So, I defined SilcDList that can be used for the purpose where
7269 predefined list structure does not exit. This can be used as
7270 such list. Now some context just can be added to the SilcDList.
7271 Currently this list is not used in the SILC just yet, though there
7272 are a lot places where this can replace dynamically allocated
7273 tables and I will fix these places, later, to use SilcDList.
7274 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7275 and use TRQ internally).
7277 Also fixed some annoying warning messages that the original TRQ
7278 code generated. Also minor changes to TRQ's Makefile.in.
7280 * Added support for querying by Client ID to both WHOIS and
7281 IDENTIFY commands into server, as required by the protocol.
7283 * Removed method function pointers from SilcBuffer structure. They
7284 weren't used to anything and just increased the context size for
7285 no good reason. This change also made silc_buffer_alloc and
7286 silc_buffer_free functions inline functions.
7288 * Disabled command flooding detection support until it's fixed so
7289 that it accepts commands in but does not execute them more than once
7292 * Added silc_net_localhost(), to return local hostname, into
7293 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7294 that must be initialized before calling silc_client_init.
7296 * Added new function: silc_server_send_notify_on_channels to send
7297 notify messages to all channels client has joined. It is assured
7298 that the message is sent only once per client.
7300 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7301 lib/silcutil/silcutil.[ch] as silc_format function. The new
7302 function is generic and is used by server as well, not only by
7303 the logging routines.
7305 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7306 the provided version string was not acceptable. Added new function:
7307 silc_ske_check_version into lib/silcske/silcske.h. The function
7308 must be implemented by the application (client or server) and it
7309 does not reside in the SKE library. The function checks the version
7310 string remote end sent.
7312 * Added back pointers (to opaque context and to SilcSocketConnection)
7313 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7315 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7316 duplicate packet context structure.
7318 * Changed `notify' client operation to send same arguments as client
7319 receives from server except for ID's. ID's are mapped to correct
7320 ID entry and that is returned. Also, if channel entry is not sent
7321 by server but the notify is for channel the channel entry is sent
7322 to application (otherwise application doesn't know that it is for
7323 channel (library gets it from packet's Destination ID)).
7325 * Added silc_client_remove_from_channels into client library to
7326 remove a client from all channels it has joined to. Used when
7327 received SIGNOFF notify from server. Added also new function
7328 silc_client_replace_from_channels to replace old ID entry with
7329 new ID entry on all channels. Used when received NICK_CHANGE
7332 * Fixed ID Cache list handling in silc_idlist_get_client in
7333 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7334 to get (or query) client by ID.
7336 * Updated TODO list.
7338 * Added connection authentication status message defined by the
7339 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7340 support for these into the code in client and server side.
7342 * Added generic function silc_client_send_command to send any command
7343 with variable argument list. Application should use this function
7344 to send commands if the command functions provided by the library
7345 does not suite for the application's user interface needs.
7347 * Added new `failure' client operation. Application is notified about
7348 received failure packet if client is executing a protocol. In this
7349 case the protocol's execution has failed.
7351 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7352 is required by the protocol.
7354 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7355 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7358 * Added status flag to SilcSKE object to indicate realtime status
7359 of the SKE protocol.
7361 * Application receives now exactly same command reply arguments as
7362 the library receives from server. However, if ID is received the
7363 corresponding ID entry is returned to the application (eg. Client
7364 ID is mapped to correct SilcClientEntry entry and that is returned).
7365 Changed command_reply client operation due to this change.
7367 * Changed all ID's in commands and in command replys as ID Payloads.
7368 Change affected both client and server side codes.
7370 All ID's sent in SILC network (with execption of ID's in SILC
7371 Packet header) are sent in ID Payload to support variable length
7374 * Server now notifies nick changes and notifies all clients on
7375 the channels about the new nickname (about the new Client ID,
7378 * Implemented CMODE command to change channel modes. Supports all
7379 channel modes defined by the protocol specs except ban and invite
7380 lists. (Also, private channel key mode is supported but support for
7381 setting private channel key in client is missing, thus, this mode
7382 has no effect on client side (except that server requires that the
7383 client uses private channel key and normal channel traffic does not
7386 Also, invite mode works per se, but INVITE command does not work
7387 yet correctly, so you can set channel as invite only channel but
7388 inviting clients to the channel does not work (it is yet to be
7389 thought what's the best way to do it).
7391 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7392 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7393 Implemented CUMODE command to change user's mode on the channel.
7394 Supports all modes defined by the protocol specs.
7396 * Added NAMES command reply to return users modes on the channel.
7398 * Removed unnecessary and slow ciphers from lib/silccrypt.
7400 * Set SO_KEEPALIVE option to connection sockets by default.
7402 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7404 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7405 redefined the Notify Payload into protocol specs.
7407 * Added silc_id_payload_parse_id to get ID directly from raw
7410 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7412 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7413 accept searching by Client ID as well.
7415 * Added support for LEAVE and SIGNOFF notify types in client library.
7417 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7418 to parse ID Payload from raw data.
7420 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7422 * Added flags parameter into silc_ske_assemble_security_properties
7423 function in lib/silcske/silcske.[ch].
7425 * Changed notify client operation to fit better for notify messages
7426 sent by server. The notify payload received from server is now
7427 passed to the application (after parsing it to SilcNotifyPayload).
7428 It is application's responsibility to retrieve the arguments
7429 from the payload and show the message the way it wants. The message
7430 sent by server is implementation specific.
7432 * Changed public keys to comply with the protocol specification.
7433 Old public keys are not supported anymore and are not compatible.
7435 * Removed nickname from Channel Payload as the latest draft removed
7436 it. The client must resolve the nickname from the NAMES command
7437 reply received when it joined the channel.
7439 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7441 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7443 * Fixed some errors in protocol specification drafts.
7445 * Created lib/silccore/silcnotify.c to implement Notify Payload
7446 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7447 generic payloads described by protocol specifications. The file
7448 includes implementations for ID Payload and Argument Payload.
7450 * Changed Command Payload implementation to use the new Argument
7451 Payload. Changed command_xxxx_payload to command_payload_xxxx
7452 to comply with SILC coding conventions.
7454 * Added suppport for Argument Payload handling in Notify Payload
7455 implementation as protocol requires it. Added the new support
7456 into server and client lib as well.
7458 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7460 * Added support for multiple nicknames on same channel. [n] is
7461 added locally to the nickname if there are more than one same
7462 nicknames on the channel.
7464 * Server now sends all nicknames that matched WHOIS request.
7465 Client also shows the list received from server.
7467 * Added TOPIC command to client side. User can now set and show
7468 current topic on channel.
7470 * Added MOTD command to client and server. Also, server sends the
7471 motd when client connects to the server.
7473 * Changed version strings to comply ISO 8601.
7475 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Fixed protocol error handling in client library. It should now
7478 cope even if the SKE fails for some reason.
7480 * Made new protocol specification drafts for submitting to IETF.
7482 * Implemented TOPIC command to server in silcd/command.c.
7484 * Added two new notify types into lib/silccore/silcnotify.h:
7485 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7486 notify nickname change and topic setting/change on a channel.
7488 * API change of command_reply operation in client library. The
7489 application gets now the status type received from server as well.
7491 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7493 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7495 * Cras fixed and optimized the packet handling even further and
7496 it should work now. Minor change to the prototype of function
7497 silc_packet_receive_process in lib/silccore/silcpacket.[ch].

7501 * Added new function into lib/silcutil/silcschedule.[ch]:
7502 silc_schedule_with_fd to select() a specified fd. The function
7503 returns after timeout expires or data arrives or goes. The
7504 function is used by packet routines to wait that all data is
7505 received from network.
7507 * Fixed data reading from network in lib/silccore/silcpacket.c.
7508 The code now assures that all data is read from the fd and then
7509 continues packet processing. This was a bug fix since the code
7510 used to drop some data in some circumstances.
7512 * Added new function into lib/silcclient/client.[ch]:
7513 silc_client_start_key_exchange to start key exchange after
7514 connection has been established to server. The code internally
7515 now uses this funtion but its main purpose was to provide it
7516 for applications that perform their own connecting. After
7517 application has created a connection it merely calls this
7518 function to start the key exchange between client and server.
7519 The library takes care of everything else after that.
7521 Updated also lib/silcclient/README to explain the usage of
7524 * Do not send to application information that connection has
7525 been established. Application gets notified it by connect
7528 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7530 * Applied cras's patch to add silc_schedule_one function. The
7531 function runs scheduler once and returns.
7533 * Fixed the scheduler after cras messed it up. The timeout
7534 handling works now as it's supposed to work.
7536 * Added into lib/silccore/ silcnotify.h to include notify
7537 message types support. Changed silc_server_send_notify*
7538 functions, in server.[ch], to support those new notify types.
7539 Added the support for the notify types into client library,
7540 as well. Added new notify client operation into ops.h in
7543 * Changed silc_server_packet_send_to_channel to send normal
7544 packets instead of just channel message packets. The function
7545 is now used to send the notify packets to channels. It is not
7546 used to send channel message packets anymore, as server never
7549 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7550 va_arg()s as it seems to require it nowadays. I guess, if SILC
7551 is compiled with older va_arg() the new code should work anyway.
7553 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7555 * Splitted core library. Core library (lib/silccore) includes
7556 now only SILC protocol specific core (and common) components.
7557 Created new utility library (lib/silcutil) that includes more
7558 generic purpose stuff. The stuff for util library was taken
7559 from the old core library. This was minor and easy split.
7561 * Created SILC Client Library (lib/silcclient) that includes
7562 implementation of the SILC client without user interface. This
7563 was major move from silc/ directory. The code has been changed
7564 so that it is transparent towards the user interface. The
7565 silc/ directory includes now the same user interface as before
7566 and it uses the new client library. Read lib/silcclient/README.
7567 Basicly, the client library performs everything else related
7568 to SILC except user interface handling. Also, configuration
7569 files are considered to be part of user interface and library
7570 does not handle them.
7572 This change also changed a lot of structures, function naming etc.
7573 Most important change was that SilcClientWindow object was
7574 renamed to SilcClientConnection in the client library. Created
7575 also new file lib/silcclient/ops.h. Also added new files
7576 silc/local_command.[ch] and silc/client_ops.[ch].
7578 All these changes were made to make it easier for user interface
7579 designers to create what ever user interface for the SILC client
7582 It is also expected that the server will be moved to lib
7583 directory as well and SILC Server Library will be created;
7584 sometimes in the future.
7586 * Removed Local commands from lib/silccore/silccommand.h as
7587 they are application specific and new client library does not
7588 handle any of those anymore.
7590 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7591 old client implementation in silc/.
7593 * Added support for callback functions in SILC_LOG_* macros.
7594 Application can now set its own callbacks that will be called
7595 instead of using the default functions that will always print
7596 the debug messages to stderr (or stdout). Also, debugging can
7597 now be disabled by setting silc_debug to FALSE and re-enabled by
7598 setting it to TRUE. Note, that logging will still work even
7599 if debugging is disabled.
7601 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7602 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7603 silc_log_reset_debug_callbacks.
7605 * To enable debugging in silc client one must give now -d
7606 option on command line.
7608 * Changed silc_schedule_init to automatically allocate task queues
7609 if they are not allocated before calling it.
7611 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7613 * Added GMP 3.1 into math library.
7615 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7617 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7618 a channel in SILC network. The packet is used by servers and
7619 routers to notify other routers that user has left a channel.
7620 This little feature was missing until now. Added the feature
7621 to protocol specification as well.
7623 Added functions: silc_server_send_remove_channel_user and
7624 silc_server_remove_channel_user into server.[ch].
7626 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7627 lib/silccore/silcpacket.h. However, they are not implemented
7630 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7632 * Fixed joining to a channel and sending channel messages
7633 between server and router. The channel message sending should
7634 now work inside a cell.
7636 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7638 * Fixed the private message sending between server and router.
7639 The private message sending should now work inside a cell.
7641 * Added silc_server_replace_id into server.[ch] to replace
7642 existing ID in the SILC network.
7644 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7645 and silc_idlist_replace_server_id into idlist.[ch] in server.
7647 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7649 * Fixed the server to server connections. Server can again now
7650 connect to router. Router to router connections probably does
7653 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7655 * Added dynamic protocol registering support. Now protocols can
7656 registered and unregistered on the fly. Patch by cras.
7658 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7660 * Added lib/contrib directory to hold routines that some platforms
7661 don't have but are needed by SILC.
7663 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7664 into lin/contrib to provide getopt() and getopt_long() for
7665 those who don't have it.
7667 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7669 * Added AWAY command to client. When away message is set and
7670 client receives a private message packet the client automatically
7671 replies to the sender with the away message.
7673 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7674 bug seemed to be the cause of recent problems when compiling
7677 * Added version detection support to SKE protocol specification
7678 and added the new changes to the SKE implementation as well.
7679 There were other minor changes in the SKE protocol as well.
7681 Many changes in lib/silcske/silcske.[ch] and in
7682 lib/silcske/payload.[ch].
7684 * Added ^U functionality, clear input line. Patch from cras.
7686 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7688 * Mainly small bugfixes on core library. Fixed some debugging
7689 logging and buffer overflow in silclog.c.
7691 * Updated config.sub and config.guess on the distribution tree.
7693 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7695 * Added command lagging support in server. Client may execute
7696 commands now only once in two seconds.
7698 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7700 * Optimized packet reception. MAC computation and checking is now
7701 also more optimized. A lot previously duplicated code is now
7702 used as generic by both client and server.
7704 * Fixed key pair generation in clientutil.c
7706 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7708 * Added into lib/silccore/silcbufutil.[ch] new function;
7709 silc_buffer_realloc.
7711 * Moved generic packet sending/encryption functions to
7712 lib/silccore/silcpacket.[ch] from client and server. Some
7713 rewriting of the functions.
7715 * Moved all generic packet reception/decryption functions to
7716 lib/silccore/silcpacket.[ch] from client and server. The
7717 packet processing is now much cleaner in both client and server.
7718 These were major changes in both client and server.
7720 * Created many common functions in server to do packet sending.
7721 Previously code were duplicated a lot, this has been removed
7724 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7726 * Rewrote major parts of the ID cache system. Don't know
7727 whether it is better now or not but at least the API is more
7730 * Major rewrite on ID cache stuff on client because of the ID
7731 cache API changes. Added idlist.c to client.
7733 * Also major rewrite on ID cache stuff on server as well.
7734 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7735 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7736 in hand, instead they are all put into the ID cache system now.
7737 All server_idlist_* routines uses ID cache now instead of
7738 traversing its own lists (those lists does not exist anymore).
7739 SilcIDList though still exists. Also, SilcXXXEntry's are
7742 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7744 * Finally made the SKE implementation compliant to the protocol
7745 specification. All mp integers are now binary encoded as
7746 opposed being HEX encoded.
7748 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7751 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7752 functions: silc_[encode/decode]_pem. Also added function
7753 silc_encode_pem_file to PEM encode with newlines ('\n') for
7756 * SILC public keys are now encoded either PEM or binary. Same
7757 option is for private keys as well. By default private keys
7758 are binary encoded and public keys PEM encoded. Silly HEX
7759 encoding were removed.
7761 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7762 function to create fingerprints.
7764 * Fixed a bug in SHA1; does not change the original data anymore.
7766 * Partly implemented INFO command on client and server side.
7767 Fixed CLEAR command. Changes to SERVER command; show current
7768 server(s) when giving command without arguments. Added
7769 VERSION command to client.
7771 * Added check to server that unregistered connections cannot
7772 execute commands (unless it is specificly allowed).
7774 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7776 * Fixed screen refresh.
7778 * Fixed channel joining bug from client. On some circumstances
7779 client tried to join to a channel it had already joined.
7781 * Added public key verification process into client's protocol.c.
7782 The client now verifies the public key from user and saves
7783 it into ~./silc/serverkeys/ directory.
7785 Added into: clientutil.[ch]: silc_client_verify_server_key.
7787 * Changed SKE protocol's silc_ske_initiator_finish function
7788 to accept callback function that verifies the received public
7789 key. Removed old silc_ske_verify_public_key function.
7791 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7793 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7794 silc_pkcs_private_key[_data]_set.
7796 * Made the password and public authentication more cleaner in
7797 server's protocol.c.
7799 * Removed historic and obsolete protocol `channel_auth' from
7800 both client and server.
7802 * Removed wrong way of sending command status messages from
7803 server to client in server's command.c. The old way violated
7804 protocol specification.
7806 Changes to silccore/silccommand.[ch]: removed
7807 silc_command_encode_status_payload -> not needed anymore,
7808 changed silc_command_encode_payload_va to accept extra
7809 argument on variable argument list. The argument type must
7810 now be provided to the function. Also, added new function:
7811 silc_command_encode_reply_payload_va which is same as
7812 normal command_encode_payload_va except command status type
7813 is provided as extra argument.
7815 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7817 * Added ~./silc directory handling. The directory includes the
7818 public and private keys for the client.
7820 Added silc_client_check_silc_dir, silc_client_create_identifier
7821 and silc_client_load_keys.
7823 * Implemented SILC protocol compliant public key. Added public
7824 and private key saving to and loading from files.
7826 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7827 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7828 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7829 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7830 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7832 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7833 silc_pkcs_load_[public/private]_key.
7835 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7837 * Added silc_server_get_route (route.[ch]) to get connection
7838 data for the fastest route for given ID.
7840 * Implemented INVITE command on client and server. The command
7841 were re-defined in the SILC Protocol Specification and the
7842 implementation now complies with the specification.
7844 * Implemented PING command on client and server.
7846 * Implemented NAMES command on client and server. The server side
7847 supports currently only normal server not router server yet.
7848 Some changes to NAMES definition in SILC protocol specification.
7850 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7852 * Implemented LEAVE command on client and server.
7854 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7855 again. This change was made to the protocol as well. Server
7856 should not violate the protocol specification anymore.
7858 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7860 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7861 was tested. SOCKS4 was not but should work anyway.
