1 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
3 * Merged version 1.1.4 of zlib. Even if it not currently in use,
4 it's good not to have security holes here.
6 * Fixed a negative refcount situtuation for the config context.
7 Affected file is silcd/serverconfig.c.
9 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
11 * ROBOdoc documented lib/silcutil/silcutil.h.
13 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
15 * Changed the silc_get_username and silc_get_real_name to
16 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
18 * Fixed the Irssi SILC Client to use the silc_get_username and
19 silc_get_real_name insted of glib routines since the glib
20 routines only corrupt stack. Fixes the Irssi SILC to work in
21 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
23 * Fixed the Irssi to not use g_get_home_dir since it crashes
24 or returns garbage on cygwin and corrupts stack. Added function
25 get_home_dir to Irssi routines. Affected files are
26 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
28 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
30 * And yet again reverted back the config thing since Johnny
31 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
34 * Fixed memory leaks from config object. Affected files are
35 silcd/serverconfig.[ch].
37 * Added support for adding new connections to the server in rehash.
38 After rehash they take effect.
40 Added support for changing the maximum allowed connections in
41 rehash. The number can grow but going smaller is not supported.
43 Added function silc_server_num_sockets_by_remote to the
44 silcd/server_util.[ch].
46 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
48 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
50 * Added preliminary checking during config parsing for a valid
51 public/private key and removed further checks in the code.
52 Affected files are silcd/serverconfig.[ch], server.c.
54 * Moved functions silc_server_drop() and silc_server_daemonise()
55 from server.c to silcd.c since they are stricly related to
56 the application activity.
58 * Reverted a small part of the automatic ref/unref since
59 it caused a double unref in some situations. Affected
60 files are silcd/silcd.[ch], server.c, serverconfig.c.
62 * Added some .cvsignore files in the lib directory.
64 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
66 * Fixed silc_net_gethostbyaddr to correctly resolve by
67 address. Affected file lib/silcutil/silcnet.c.
69 * Fixed the notify relaying to client. The HMAC to be used
70 with relayed packets ws wrong and caused decryption failure
71 at the client end. Affected file is silcd/packet_receive.c.
73 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
75 * Created new branch silc_protocol_1_0_branch.
77 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
79 * Changed the silc_server_config_* routines to be SilcServer
80 independent. They are now officially application specific code
81 and not part of generic server implementation. Affected files
82 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
84 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
86 * Added automatic referencing of config context in the
87 silc_server_config_alloc, and automatic unreferencing in the
88 silc_server_config_destroy. Affected files are
89 silcd/serverconfig.[ch], silcd/silcd.c.
91 * Fixed the silc_log_quick handling in the logging routines.
92 It didn't log quickly when it was TRUE. Affected file is
93 lib/silcutil/silclog.c. Also the flush delay was set even
94 if it was 0 in config file. Affected file is
97 * Added support for changing key pair of the server in rehash.
98 Affected file silcd/server.c.
100 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
102 * Fixed the TOPIC_SET notify to not cras. It changed the topic
103 too early, before getting the channel entry. Affected file
104 is silcd/packet_receive.c.
106 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
108 * Added functions silc_server_config_[ref/unref], these are used
109 to prevent that the config object is destroyed.
111 No longer directly affect global variables silc_log_quick and
112 silc_log_delay, they are first cached inside the config object
113 and then applied with silc_server_config_setlogfiles().
115 silc_server_config_set_defaults() is now internal to
116 serverconfig.c, there are no reasons to show this internal stuff
119 Affected files are silcd/serverconfig.[ch].
121 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
122 fprintf's to stderr, since some code may be executed again after
123 the server went into the background. Affected files are
126 * Added rehash support. Added function silc_server_rehash() that
127 will perform all the basic tasks of the rehashing procedure.
129 * Added command line option `-x, --hexdump'. This will enable the
130 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
131 The option `--hexdump' implies `--debug'.
133 * Fixed a bad bug in the logging APIs (silcutil library) where
134 the application would crash after calling silc_log_reset_all().
136 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
138 * Fixed the KICKED notify handling in client library to
139 correctly remove the channel and all entries from the
140 channel when I was kicked. This bug crashed the client.
142 Fixed yet another but in KICKED notify handling to remove
143 the kicked client correctly from the channel.
145 Affected file is lib/silcclient/client_notify.c.
147 * Fixed a minor bug in looking up correct client entry
148 in KICKED notify in server. Affected file is
149 silcd/packet_receive.c.
151 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
152 sources correctly to distribution. Fixes --with-gmp option.
154 * Removed the manual rehashing from ID Cache, and changed it
155 to use the SILC Hash Table's auto rehash feature. Affected
156 file is lib/silccore/silcidcache.c.
158 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
160 * Fixed a bug in the silc_client_nickname_format function that
161 handles the multiple same nickname formatting. Two clients
162 with same nickname caused problems after the first one left
163 and rejoined. It didn't format the nickname correctly.
164 Affected file is lib/silcclient/idlist.c.
166 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
168 * Don't change the topic if olod topic is same as new one.
169 Affected file is silcd/packet_receive.c.
171 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
173 * Added cross-reference support to the SILC Documentation
174 generator. All types across all HTML files are now cross-
175 referenced. Affected files util/robodoc/generator.c and
176 scripts/silcdoc/silcdoc.
178 * Added file lib/silcutil/silctypes.h to include all the
179 arithmetic type definitions and some macros. Removed
180 includes/bitmove.h and moved macros to silctypes.h.
182 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
184 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
186 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
188 * Added `type' argument to silc_id_payload_parse_id function which
189 now returns the type of the ID to the sent pointer. Affected
190 file is lib/silccore/silcid.[ch].
192 * Added check for CMODE_CHANGE notify type that mode change is
193 allowed by the sender. Affected file silcd/packet_receive.c.
195 * Added check for CUMODE_CHANGE notify type that mode change is
196 allowed by the sender. Affected file silcd/packet_receive.c.
197 Added the ID type as CUMODE_CHANGE notify type as argument
198 to the `notify' client operation. Affected files are
199 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
201 * Added function silc_client_add_server to the client library.
202 Added support for resolving also channel and server info when
203 received unknown entity in notify packet. Affected files are
204 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
206 * Added function silc_command_get_status to return the command
207 status from the command reply's argument payload. Affected files
208 are lib/silccore/silccommand.[ch].
210 * Added check for KICKED notify type that the kicking is
211 allowed by the client. Affected file silcd/packet_receive.c.
213 * Created function silc_get_input which can be used to get input
214 (echo on or off) from user on command line. Affected files are
215 lib/silcutil/silcutil.[ch].
217 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
219 * Optimized silc_server_packet_relay_to_channel function.
220 Added new function silc_channel_message_payload_encrypt which
221 can be called directly if channel message payload needs to
222 be encrypted and is already encoded (no need to call _encode
223 function). Packet relaying is now done by router without any
224 extra memory allocations. Affected files are
225 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
228 * Fixed the INVITE notify handling. It took wrong arguments
229 as invite list and invite delete. Affected file is
230 silcd/packet_receive.c.
232 * Added check for TOPIC_SET notify type that the topic change is
233 allowed by the client. Affected file silcd/packet_receive.c.
235 * Added check for INVITE notify type that inviting is allowed by
236 the client. Affected file silcd/packet_receive.c.
238 * Changed the silc_server_client_on_channel to return the
239 SilcChannelClientEntry as well. Moved the function
240 silc_server_check_cmode_rights to server_util.[ch].
241 Affected files are silcd/server_util.[ch], silcd/command.c.
243 * Added function silc_server_check_umode_rights to check whether
244 changing client's user mode is allowed. Added check for
245 UMODE_CHANGE notify type that the umode change is allowed
246 by the client. Affected files are silcd/server_util.[ch],
247 silcd/packet_receive.c and silcd/command.c.
249 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
251 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
252 ID length. It ignored that ID can be IPv6 based as well.
253 Affected file lib/silccore/silcpacket.h.
255 * Fixed the silc_id_id2str and silc_id_str2id to take the
256 IPv6 address offset's into consideration. Affecte file is
257 lib/silccore/silcid.c.
259 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
261 * Fixed the internal Unix scheduler functions to check for
262 NULL context they may receive. The affected file is
263 lib/silcutil/unix/silcunixschedule.c.
265 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
267 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
268 can specify different directory with --home command line
269 parameter. Affected files irssi/src/silc/core/client_ops.c,
272 * SILC-specific commands aren't now executed if the active server
273 isn't of SILC-type, so there won't be problems with having
274 IRC and SILC protocol support in same client. Affected files
275 irssi/src/silc/core/silc-channels.c, silc-servers.c,
278 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
280 * Improved the signal support in SILC Schedule. Added new
281 function silc_schedule_signal_call which is used by application
282 to mark a signal to be called. It is now safe to perform
283 any kind of tasks in signal callbacks since it is guaranteed
284 that the application specified signal callback is called
285 after the signal is over. Affected files are
286 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
288 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
290 * Added `name' field to SilcChannelPrivateKey to represent
291 application given name for the key. Moved also the context from
292 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
293 Added the `name' argument also to the function
294 silc_client_add_channel_private_key.
296 Added function silc_client_current_channel_private_key to set the
297 current channel private key in use.
299 Added "change" command to KEY command which can be used to change
300 the current channel private key. Bound the command also to
303 Also affected files lib/silcclient/client_channel.c,
304 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
306 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
308 * Added silc_rng_get_byte_fast function in to the
309 lib/silccrypt/silcrng.[ch].
311 * Changed the interface of silc_packet_assemble and the
312 silc_packet_send_prepare. If silc_packet_assmble is now
313 called the application does not call silc_packet_send_prepare
314 because the library will call it automatically. These
315 interfaces now also return a reference to the outgoing buffer
316 which includes the assembled packet, which the application can
317 use to encrypt the packet.
319 Affected files are lib/silccore/silcpacket.[ch],
320 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
321 silcd/packet_send.c, server_backup.c and packet_receive.c.
323 * Fixed a packet sending bug on very high load, where outgoing
324 packet queue wasn't handled correctly and packets got corrupted.
325 Affected files are lib/silcutil/*/silc*sockconn.c,
326 lib/silcclient/client.c and silcd/server.c.
328 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
330 * Added macro SILC_PACKET_DATALEN which can be used during
331 packet assembling to check whether the data to be added to
332 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
333 len is truncated until it fits it.
335 Added checks for maximum length of channel message payload and
336 private message payload also.
338 Added checks for maximum packet length in server and in
341 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
342 lib/silcclient/client.c, lib/silccore/silcchannel.c and
343 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
344 lib/silcclient/client_prvmsg.c.
346 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
348 * Added silc_server_packet_queue_purge call to the
349 silc_server_disconnect_remote to assure that all data in the
350 queue before disconnecting is sent to the network. Affected
353 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
355 * Added the deleting of server's own ID cache entry to the
356 silc_server_free function. Free also everything else that
357 has been allocated in silc_server_init. The affected file
360 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
362 * Added functions silc_parse_version_string, silc_version_to_num,
363 and silc_ske_parse_version to parse SILC protocol style version
364 strings. Affected files lib/silcutil/silcutil.[ch] and
365 lib/silcske/silcske.[ch].
367 * Added new configuration params: version_protocol, version_software
368 and version_software_vendor to specify what version the remote
369 host must at least be to be able to connect to server. The vendor
370 string can be regex matched too. Added new function
371 silc_server_connection_allowed to check maximum number of allowed
372 connections, and allowed versions for incoming connections.
373 Affected files are silcd/server.c, server_util.[ch] and
376 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
378 * Added preliminary support for signals in scheduler. The
379 signals we care about are now blocked always when the scheduler
380 is locked. This way we can synchronise the use of signal with
381 scheduler. It is guaranteed that when signal occurs the scheduler
382 is not locked, and thus new tasks can be safely added to the
385 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
386 to silc_schedule_internal_init and silc_schedule_internal_uninit.
387 Added new platform specific routines
388 silc_schedule_internal_signals_[un]block and
389 silc_schedule_internal_signal_[un]register.
391 Added new functions to SILC Schedule API:
392 silc_schedule_signal_[un]register. Each signal that application
393 is going to use should be registered to the scheduler.
395 Affected files are lib/silcutil/silcschedule.[ch],
396 lib/silcutil/*/silc*schedule.c.
398 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
400 * Check for unauthenticated client and server in the
401 silc_server_new_client and silc_server_new_server functions.
402 Affected file silcd/packet_receive.c.
404 * Added function silc_string_is_ascii to check whether given
405 string is 7-bit ASCII string. Affected files are
406 lib/silcutil/silcutil.[ch].
408 * Added function silc_id_is_valid_server_id into the
409 silcd/serverid.c and added checking for valid Server ID's in
410 silc_server_new_server. The Server ID must always be based
411 on the server's public IP address.
413 * Added logging of DISCONNECT packet message in the server.
414 Affected file silcd/server.c.
416 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
418 * Changed all library interfaces that use Global RNG to also
419 accept SilcRng as argument. Affected files are
420 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
421 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
422 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
423 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
426 * Added function silc_pkcs_generate_key to the
427 lib/silccrypt/silcpkcs.[ch] for applications so that they
428 don't need to do pkcs->pkcs->init calls anymore.
430 * Remove SilcSocketConnection from the SFTP API since it really
431 wasn't needed there. The application has the information
432 saved in its contexts anyway and the SFTP layer doesn't need
433 know about it. Affected files lib/silcsft/silcsftp.h and
434 lib/silcsftp/sftp_[server/client].c.
436 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
437 The SilcSimContext is not SilcSim.
439 * Fixed possible buffer overflows in silc_id_render in the
440 lib/silcutil/silcutil.c.
442 * On EPOC the global crypto module lists are not used at all
443 in the crypto library. Added support for using the constant
444 algorithm list on EPOC. Affected files are
445 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
448 * Fixed the handling of third parameter of KICKED notify, since
449 it was mistakenly updated to SILC Protocol 1.0 even though it
450 is to be included in 1.1. Since it is not in 1.0 it is not
451 mandatory, and this fix now handles it only if it is provided,
452 and it is not error if it is not provided. Affected file
453 lib/silcclient/client_notify.c.
455 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
457 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
458 client. Affected file irssi/src/silc/core/client_ops.c.
460 * Merged with Irssi 0.8.4 from irssi.org CVS.
462 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
464 * Check for valid socket connection in client entries before
465 sending any messages. Fixes a crash, but doesn't fix some
466 other underlaying bug that is lurking there. Affected
467 file silcd/packet_send.c.
469 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
471 * $usermode, $cumode and $cumode_space expandos shouldn't do
472 anything with non-SILC server records. Affected file
473 irssi/src/silc/core/silc-expandos.c
475 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
477 * Fixed the silc_net_check_[host/local]_by_sock to support
478 IPv6 bound sockets as well. Now they can return IPv6 addresses
479 as well. Affected file lib/silcutil/silcnet.c.
481 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
482 Affected lib/silcutil/unix/silcunixnet.c.
484 * Fixed ID rendering (at least on some platforms, not NetBSD)
485 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
487 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
489 * Added silc_hash_public_key and silc_hash_public_key_compare
490 functions to be used with SilcHashTable. They can be used to
491 hash public keys and compare public keys in hash table. Affected
492 file lib/silcutil/silcutil.[ch].
494 * Added support for specifying multiple public keys for Client
495 connection section in server configuration file. This makes it
496 possible to accept multiple public keys from same host, or to
497 make a section that accepts any incoming host, and have the
498 accepted public keys listed in the section.
500 Added functions silc_sever_[find/get]_public_key, added the
501 support for this actually to all connection sections but only
502 the Client section is currently allowed to specify multiple
505 Affected files are silcd/server.c, server_internal.h,
506 command.c, protocol.c, server_util.[ch], packet_receive.c.
508 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
510 * Merged Irssi 0.8.2 from irssi.org CVS.
512 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
514 * If silc_debug is TRUE, also output standard logging messages
515 to stderr with the debug output.
517 Made silc_log_reset_all() flushing all channels before returning.
518 Also fixed some documentation typos.
520 Affected files are lib/silcutil/silclog.[ch].
522 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
524 * Fixed the server to check correctly the amount of connections
525 from single host, by checking also the type of the connection.
526 Fixed also the comparison of number of connections and number
527 of allowed connections. Affected files are silcd/server.c,
530 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
532 * Fixed the USERS command reply to save the user's mode on the

677 the SKE interface a bit.
679 * Fixed padding problem in PKCS#1. The padding was not actually
680 random since the random number generator was used incorrectly.
681 This security bug affects only when encrypting with PKCS#1, and
682 it is not currently used at all in SILC. SILC only use signing
683 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

764 algorithm parts and created new file silcalgs.conf, that
765 is now included from the example_silcd.conf.in.
767 * Optimized the silc_server_connect_to_router_second to take
768 the connection configuration object from the SilcServerConnection
769 object instead of finding it during the connecting phase.
770 Added the configuration object to SilcServerConnection struct.
771 Affected files silcd/server_internal.h, server.c.

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

855 * Fixed the file transfer's key agreement payload to include
856 zero port also if the hostname is NULL because it could not
859 Call file transfer monitor callback now also if error occurs
860 during key agreement protocol.
862 Changed the silc_client_file_send interface to return the
863 SilcClientFileError instead of session id. The session ID
864 is returned into pointer provided as argument.

883 * Fixed the channel message payload decryption in the function
884 silc_channel_message_payload_decrypt to not modify the original
885 buffer before it is verified that the message decrypted
886 correctly. Otherwise, next time it is called with correct
887 channel key it won't encrypt since the payload is corrupted.
888 Affected file lib/silccore/silcchannel.c.
890 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

904 become invalid in the callback but it was referenced after
905 the callback returned.
907 Do not allow auto rehashing of hash table during the
908 silc_hash_table_foreach operation, for same reasons as it is
909 not allowed for SilcHashTableList. Affected files are
910 lib/silcutil/silchashtable.[ch].

934 lib/silcclient/idlist.[ch].
936 * Fixed a bug in hash table tarversing. While the hash table
937 is traversed with SilcHashTableList the table must not be
938 rehashed. It is now guaranteed that auto rehashable tables
939 are not rehashed while tarversing the list. Also defined that
940 silc_hash_table_rehash must not be called while tarversing
941 the table. Added function silc_hash_table_list_reset that must
942 be called after the tarversing is over. The affected files are
943 lib/silcutil/silchashtable.[ch].
945 * Changed all hash table traversing to call the new
946 silc_hash_table_list_reset in server and in client library.
948 * Added function silc_client_on_channel to return the

965 sender's old command identifier was not saved back to the
966 sender's command context, fixed now. The affected file is
969 * Create the key in JOIN command of the router did not return
970 the channel key, added check for this. Affected file is
973 * Fixed a channel ID update bug in JOIN command reply. Do
974 not directly upgrade the ID but call the function
975 silc_idlist_replace_channel_id if the ID was changed.
976 Affected file silcd/command_reply.c.
978 * Fixed memory leaks from command calling if it would fail.
979 Affected file silcd/command.c.

1083 * Fixed GETKEY command to first resolve client, and then
1084 resolve the server only if the client was not found, instead
1085 of resolving both at the same time. Affected file is
1086 lib/silcclient/command.c.
1088 * Added silc_client_start_key_exchange_cb and lookup the
1089 remote hostname and IP address before starting the key
1090 exchange with server. The affected file is
1091 lib/silcclient/client.c.
1093 * The server's public key is now saved using the IP address
1094 of the server and not the servername for the filename.
1095 The hostname public key filename is checked as an fall back
1096 method if the IP address based filename is not found.
1098 Fixed the GETKEY command to save the fetched server key
1099 in correct filename.
1101 Print the remote server's hostname now when new key is
1102 received during connection process. Affected file is
1103 irssi/src/silc/core/client_ops.c.
1105 * Return always our own public key to the client if it asks
1106 for it with GETKEY command. Affected file silcd/command.c.
1108 * Removed the use_auto_addr variable from default config
1109 file since it was in wrong section. Affected file is
1112 * Fixed TOPIC_CHANGE notification to not route it when it
1113 was sent using silc_server_send_notify_to_channel function.
1114 Affected file silcd/command.c.
1116 * Fixed silc_server_send_notify_kicked to send the kicker's
1117 Client ID also, it was missing. Affected files are
1118 silcd/command.c, silcd/packet_send.[ch].
1120 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1122 * Do not save client history information in SERVER_SIGNOFF.
1123 Fixes the bug in normal server that it does not detect
1124 the client becoming valid after the server becomes back
1125 online. Affected file silcd/server_util.c.
1127 * Added `sock_error' field into the SilcSocketConnection
1128 context. When error occurs during socket operation (read
1129 or write) the error is saved. Added also new function
1130 silc_socket_get_error to return human readable socket error
1131 message. Affected files are lib/silcutil/silcsockconn.[ch],
1132 lib/silcutil/unix/silcunixsockconn.c, and
1133 lib/silcutil/win32/silcwin32sockconn.c.
1135 * The server now prints the socket error message in the
1136 signoff for client. Affected file silcd/server.c.
1138 * Fixed the `created' channel information sending from router
1139 to server in JOIN command. Checks now whether the channel
1140 really was created or not and set it according that.
1142 Fixed the JOIN command to use the client entry's current
1143 ID during the joining procedure instead of the one it sent
1144 in the command (it is checked though), since it can change
1145 between the packet processing and command processing, and
1146 would just case unnecessary pain in the client end. Affected
1147 file silcd/command.c.
1149 * Fixed a channel key payload sending to use correct channel
1150 ID when the server was forced to change the channel's ID by
1151 router. Router sent the key payload with the old Channel ID.
1152 Affected file silcd/packet_receive.c.
1154 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1156 * Call silc_server_save_channel_key only if the key payload
1157 was provided in the JOIN command's command reply. Affected
1158 file silcd/command_reply.c.
1160 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1162 * Fixed silc_mp_sizeinbase to return the value correctly with
1163 MPI. Affected file lib/silcmath/mp_mpi.c.
1165 * Fixed the stop_server signal to correctly stop the scheduler
1166 and gracefully stop the server when SIGTERM or SIGINT signals
1167 are received. Affected file silcd/silcd.c.
1169 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1171 * Simple handling of TERM and HUP signals. Also added some log
1172 flushing call around. Affected file is
1175 * Fixed small bugs in silclog.c. Now buffering output will take
1176 effect after 10 seconds since startup: This will ensure that
1177 no important startup messages are lost. Also output redirection
1178 will preserve original format ([Date] [Type] message).
1179 Affected file is lib/silcutil/silclog.c.
1181 * Added two options to the config file, in the logging section:
1182 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1183 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1185 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1187 * Do not print the warning about log files not being initialized
1188 more than once to avoid excess logging. Affected file is
1189 lib/silcutil/silclog.c.
1191 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1192 the SIM copying in make install in Makefile.am.pre.
1194 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1196 * Rewritten silclog APIs. Globally interesting changes follows:
1197 silc_log_set_files() changed to silc_log_set_file().
1198 silc_log_set_callbacks() changed to silc_log_set_callback().
1199 ROBOdoc documented silclog header file.
1200 SilcLogCb now returns bool to wether inihibit the default
1201 handler or not (to keep the old behaviour return always TRUE).
1202 The new APIs should also fix the problem of the
1203 silcd_error.log file that was written in the current directory.
1206 Log files streams will remain opened after silc_log_set_file()
1207 call, means less CPU usage notably on high traffic servers.
1208 File streams are now full buffered, and flushed to the disk
1209 every 5 minutes, lesses HD activity and CPU usage.
1210 Messages can be redirected, allowing admins to configure
1211 one single logfile for all server messages.
1212 the silc_log_quick global variable to activate fast-logging.
1213 Affected files lib/silcutil/silclog.[ch]
1215 * Changed some code to conform new silclog APIs. Affected
1216 files are doc/example_silcd.conf.in, silcd/server.c
1217 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1220 * Fixed a memory leak that could occur in some situations.
1221 Affected file silcd/serverconfig.c.
1223 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1225 * Added the silc_client_del_client to remove the client from
1226 all channels as well. Affected file lib/silcclient/idlist.c.
1228 * Fixed the client library to correctly remove the client
1229 from all channels when the client entry is being destroyed.
1230 Affected file lib/silcclient/client_notify.c, command.c.
1232 * Added auto-nicking support to the client library. If the
1233 applicatio now sets client->nickname it will be sent to the
1234 server after connecting by the library. This way for example
1235 SILCNICK (or IRCNICK) environment variables will have effect
1236 and always change the nickname automatically to whatever
1237 it is wanted. Affected file lib/silcclient/client.[ch].
1239 * Renamed silc_server_command_bad_chars to the
1240 silc_server_name_bad_chars and moved it to the
1241 silcd/server_util.[ch]. Added also new function
1242 silc_server_name_modify_bad to return nickname that
1243 includes bad characters as new nickname without those
1244 bad characters. This check and modify is now used in
1245 silc_server_new_client when the username is initially set
1246 as nickname, so it must be checked to be valid nickname.
1247 Affected file silcd/packet_receive.c.
1249 * The nickname length is now taken from the packet for real
1250 and not trusted to strlen() since it clearly can return
1251 wrong length for nickname including bad characters. This
1252 also applies to channel names. Affected file silcd/command.c.
1254 * Removed the lib/silcsilm/modules directory. Modules are now
1255 compiled into the lib/silcsim. Fixed the copying of the
1256 modules to follow symbolic links in Makefile.am.pre.
1258 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1260 * Fixed silc_string_regexify list creation. Fixes bugs with
1261 BAN and INVITE commands in server. The affected file is
1262 lib/silcutil/unix/silcunixutil.c.
1264 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Removed the command destructor entirely from the server's
1267 command and command reply routines. It is not needed, and
1268 its usage was buggy and caused crashes. Affected files are
1269 silcd/command[_reply].[ch].
1271 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * Cancel protocol and NULL sock->protocol if timeout
1274 occurred during protocol. Affected file silcd/server.c.
1276 * Cancel protocol timeouts always before calling the final
1277 callback, to assure that after final callback is called
1278 no other state will be called for the protocol anymore.
1279 Affected file silcd/protocol.c.
1281 * Print error log if incoming connection configuration could
1282 not be found. Affected file silcd/server.c.
1284 * Fixed JOIN command to correctly save the founder mode
1285 to the client on normal SILC server, when the channel
1286 was created by the router. Affected file silcd/command.c.
1288 * Fixed LIST command (hopefully) to send correct reply
1289 packets. Affected file silcd/command.c.
1291 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1293 * The silc_packet_receive_process now returns FALSE if the
1294 read data was invalid packet, and TRUE if it was ok.
1296 The server now checks that if unauthenticated connection
1297 sends data and its processing fails the server will close
1298 the connection since it could be a malicious flooder.
1300 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1302 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * Make sure the warning about error opening a log file is
1305 printed only once and not everytime it fails (produces
1306 too much useless log). Affected file lib/silcutil/silclog.c.
1308 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1310 * Made the silc_server_daemonise() function more readable.
1311 Affected file silcd/server.c.
1313 * Pid file is now optional, the user may comment it out from
1314 the config file. Removed define SILC_SERVER_PID_FILE, we
1315 don't need a default any longer. Affected file
1316 configure.in.pre, lib/Makefile.am.pre.
1318 * Make some use of the pid file. The server now dies at startup
1319 if it detects a valid pid file on his path. The server would
1320 die anyway in this circumstance, because of the bind() failure.
1321 Affected file silcd/silcd.c.
1323 * No longer compiling lib/dotconf.
1325 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Fixed JOIN command parsing not to crash. Affected file
1328 lib/silcclient/command.c.
1330 * Fied the NICK_CHANGE notify to add the new client entry
1331 even it is resolved. This removes an <[unknown]> nick
1332 thingy bug in the client. Affected file is
1333 lib/silcclient/client_notify.c.
1335 * Do not try to allocate 0 bytes (efence does not like it)
1336 in lib/silccore/silccomand.c when encoding payload.
1338 * Do not take IRCNICK as nickname in Irssi SILC client since
1339 it is not possible to set nickname before hand connecting
1340 the server (TODO has an entry about adding auto-nicking
1343 * Changed the silc_server_command_pending to check whether
1344 there already exists an pending entry with the specified
1345 command, command identifier and pending callback. This is
1346 to fix IDENTIFY and WHOIS related crashes that may register
1347 multiple pending commands with same identifier. Affected
1348 file silcd/command.c.
1350 * Fixed the server to reconnect to the router even if it
1351 was already reconnecting and EOF was received. This to
1352 fix a possibility that the server wouldn't ever try to
1353 auto-reconnect to the router. Affected file silcd/server.c.
1355 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1357 * Fixed the server's password authentication to use the
1358 length of the locally saved password, and not the one
1359 sent in the packet. Affected file silcd/protocol.c.
1361 * Fixed same password authentication problem in the
1362 Authentication Payload handling routines in
1363 lib/silccore/silcauth.c.
1365 * Yet another password authentication problem fixed with
1366 channel password handling in silcd/command.c.
1368 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * If first character of string in silc_parse_userfqdn is '@'
1371 then do not parse it. Affected file is
1372 lib/silcutil/silcutil.c.
1374 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1376 * Fixed minor bug in IDENTIFY command reply sending, which
1377 caused various weird problems during JOIN when it was
1378 resolving names for users. Affected file silcd/command.c.
1380 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1382 * Fixed the IDENTIFY command reply sending to chech better valid
1383 clients. It was possible to send incomplete list of replies.
1384 Affected file silcd/command.c.
1386 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1388 * Added silc_client_command[s]_[un]register functions now to
1389 dynamically register the commands in client library. Removed
1390 the static table of commands. This allows the client library
1391 to call commands without causing the application to know about
1392 what commands library has called.
1394 Removed the INFO command reply kludge to detect when the command
1395 was called by library. Now library use its own command reply
1396 function for INFO command.
1398 Added function silc_client_command_call to call a command.
1399 Application can use it to call command, not access the structure
1402 Now all commands that are sent by the client library (not
1403 explicitly sent by application) use own command reply functions.
1405 Affected files around lib/silcclient/ and in
1406 irssi/src/silc/core/.
1408 * Fixed the WHOIS command reply sending to chech better valid
1409 clients. It was possible to send incomplete list of replies.
1411 Fixed the WHOIS and IDENTIFY to send the request to router
1412 if normal server did not do it and did not find any results.
1414 Affected file silcd/command.c.
1416 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Moved the internal data from SilcClient context into its
1419 own file, not accesible to application. Affected files
1420 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1421 and other files in client library.
1423 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * Added doc/examples installation target in Makefile.am.pre.
1428 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1430 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1431 commands the found client entry will be removed from the
1432 cache, after notifying application about the error. Affected
1433 file lib/silcclient/command_reply.c.
1435 * Changed the /MSG to check for exact nickname user gave, and
1436 not let `nick' match `nick@host' if it is only one found. Now,
1437 user must type the exact nickname (like nick@host2) even if
1438 there are no more than one same nicks found. This is to avoid
1439 a possibility of sending nickname to wrong nickname since
1440 `nick' could match `nick@host'. Affected file is
1441 irssi/src/core/silc-servers.c.
1443 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1445 * Do not print "you are now server operator" or similar when
1446 giving /away command. Affected files are
1447 irssi/src/silc/core/client_ops.c, silc-servers.h.
1449 * Made the silc_server_command_pending_error_check to send
1450 the same command reply payload it received back to the
1451 original sender of the command. This way all arguments
1452 that was received by the server will be received by the
1453 client too. Affected file silcd/command.c.
1455 * Added the silc_idcache_add to return the created cache entry
1456 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1458 * Add global clients to expire if they are not on any channel.
1459 This is because normal server will never know if they signoff
1460 if they are not on any channel. The cache expiry will take
1461 case of these entries. This is done by normal servers only.
1462 The affected files are silcd/command_reply.c,
1463 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1465 * If server receives invalid ID notification for WHOIS or
1466 IDENTIFY and the ID exists in the lists, it is removed.
1467 Affected file silcd/command_reply.c.
1469 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1470 in client then client entry that it matches is searched and
1471 the nickname is printed on the screen for user. Affected
1472 file irssi/src/silc/core/client_ops.c.
1474 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1476 * Use cache entry expire time in the LIST command reply to
1477 purge old entries from the cache after the LIST command
1478 reply has been received. This way we don't have non-existent
1479 entries in the cache for too long. Affected file is
1480 silcd/command_reply.c.
1482 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1484 * If we are normal server, and we've not resolved client info
1485 in WHOIS or IDENTIFY from router, and it is global client,
1486 we'll check whether it is on some channel. If it is not
1487 then we cannot be sure about its validity and will resolve it
1488 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1489 file silcd/command.c.
1491 * Search channel by name (if possible) rather than by ID
1492 in IDENTIFY command's command reply. Affected file is
1493 silcd/command_reply.c.
1495 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1497 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1498 Updated specs and implemented it. Affected file silcd/command.c,
1499 silcd/packet_send.c and silcd/packet_receive.c.
1501 * Implemented the <founder auth> payload handling in the JOIN
1502 command. If provided all conditions for channel joining
1503 except requirement to provide correct passphrase can be
1504 overrided by the channel founder. Updated the protocol specs.
1505 Affected file silcd/command.c.
1507 Added support for founder auth in JOIN command in client
1508 library. Fixed the parsing of the JOIN command now to support
1509 all options as they should be. The affected file is
1510 lib/silcclient/command.c.
1512 * Optimized the WHOIS and IDENTIFY commands to send the request
1513 to router only if it includes nicknames or other names. If
1514 they include only IDs then check the local cache first before
1515 routing. Affected file is silcd/command.c.
1517 * Added channels topic announcements. Affected file is
1518 silcd/packet_receive.c and silcd/server.c.
1520 * Fixed the silc_server_send_notify_topic_set to really destine
1521 the packet to channel. Affected file silcd/packet_send.c.
1523 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1524 library. Affected file lib/silcclient/client_notify.c.
1526 * Added UMODE announcements. Affected file silcd/server.c.
1528 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1530 * Memory leak fixes in:
1532 lib/silcutil/silcsockconn.c
1533 lib/silcske/silcske.c
1534 lib/silcske/groups.c
1536 lib/silccrypt/silcpkcs.c
1537 lib/silccore/silccommand.c
1538 lib/silccore/silcidcache.c
1543 * ROBOdoc documented the lib/silcske/groups.h file and a
1544 bit changed the interface for better.
1546 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1548 * Update the client entry context in the ID cache after
1549 nick change. Affected file lib/silcclient/command.c.
1550 Fixes the CUMODE command when regaining founder privileges,
1551 and a little WHOIS problem.
1553 * Fixed silc_net_gethostbyname to correctly call the
1554 inet_ntop. Affected file lib/silcutil/silcnet.c.
1556 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1558 * Added IPv6 support checking to the configure.in.pre, added
1559 also --enable-ipv6 option to override the check. Affected
1560 file configure.in.pre.
1562 * The silc_thread_create now calls the start function
1563 directly if threads support is not compiled in. Removes
1564 ugly #ifdef's from generic code. Affected files are
1565 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1567 * Added silc_net_gethostby[name/addr]_async to asynchronously
1568 resolve. Affected files are lib/silcutil/silcnet.[ch].
1570 * Added support for rendering IPv6 based server, client and
1571 channel IDs. Affected file lib/silcutil/silcutil.c.
1573 * Added support for creating IPv6 based server IDs. Affected
1574 file is silcd/serverid.c.
1576 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1578 * Added silc_net_gethostby[addr/name] into the
1579 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1580 routines. Added silc_net_is_ip[4/6]. Affected file is
1581 lib/silcutil/unix/silcunixnet.c. All routines that take
1582 address as argument now supports both IPv4 and IPv6 addresses.
1584 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1586 * Fixed LIST command reply sending in server. Affected file
1589 * Server now sends the kicker's client ID in the KICK notify
1590 to the kicked client. Affected file silcd/command.c.
1592 * The client library now parses the kickers client ID and
1593 UI displays it. Affected files lib/silcclient/client_notify.c
1594 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1596 * Made all payload parsing function prototypes consistent.
1597 They all take now const unsigned char * and uint32 pair as
1598 the payload data instead of SilcBuffer. Changes all around
1599 the source tree. Other unsigned char* -> const unsigned char*
1600 changes around the tree as well.
1602 * Optimized SFTP client and server packet sending not to
1603 allocate new buffer for each packet but to recycle the
1604 first allocated buffer. Affected files are
1605 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1607 * Optimized the SFTP client to use SilcList instead of
1608 SilcDList for requests, because it is faster. Affected file
1609 is lib/silcsftp/sftp_client.c.
1611 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1612 into lib/silccore/silcid.[ch].
1614 Renamed silcpayload.[ch] into silcargument.[ch].
1616 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1618 * If client entry is deleted with active key agreement
1619 session, abort the session.
1621 The silc_client_abort_key_agreement now calls the completion
1622 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1624 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1627 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1629 * Don't use __restrict in older GCC's. Affected file is
1630 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1632 * silc_net_localhost now attempts to reverse lookup the
1633 IP/hostname. Affected file lib/silcutil/silcnet.c.
1635 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1636 command. It can be used to gain founder privileges at
1637 the same time when joining the channel.
1639 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1640 kicker's client ID as well. Updated protocol specs.
1642 Defined that the server must send SILC_COMMAND_IDENTIFY
1643 command reply with error status to client who sent
1644 private message with invalid client ID.
1646 Updated the protocol specification.
1648 * Added silc_server_send_command_reply to send any
1649 command reply. Affected file silcd/packet_send.[ch].
1651 * Added silc_id_payload_encode_data to encode ID payload
1652 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1654 * The server now send IDENTIFY command reply with error
1655 status if client ID in private message is invalid. Affected
1656 file silcd/packet_receive.c.
1658 * Save the server key file with server's IP address in
1659 the filename instead of hostname. The affected file is
1660 irssi/src/silc/core/client_ops.c.
1662 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1664 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1667 * Added libtool support for compiling shared objects in
1668 lib/silcsim. Affected file configure.in.pre and
1669 lib/silcsim/Makefile.am. Original patch by cras.
1671 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * Pid file configuration, and server's config file fixes
1674 patch by toma. Updated CREDITS file.
1676 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1678 * Fixed silc_client_channel_message to not try to decrypt
1679 the message twice if it resolved the destination client
1680 information. This could cause of dropping one channel
1681 message. Affected file lib/silcclient/client_channel.c.
1683 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1686 lib/silcclient/client.c. This function is used when the SILC
1687 Client is run under some other scheduler, or event loop or
1688 main loop. On GUI applications, for example this may be
1689 desired to used to run the client under the GUI application's
1690 main loop. Typically the GUI application would register an
1691 idle task that calls this function multiple times in a second
1692 to quickly process the SILC specific data.
1694 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1696 * Fixed silc_server_drop() for dropping the supplementary
1697 groups as well, this could cause a security hole on some
1700 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1702 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1705 * Write PID file after dropping privileges. Added -F option
1706 to run server on foreground. A patch by debolaz.
1707 Affected files silcd/server.c, silcd/silcd.c.
1709 * Fixed MOTD to return the MOTD file server name. Affected
1710 file silcd/command.c.
1712 * Added INFO command reply handling to the Irssi SILC Client.
1713 Affected file irssi/src/silc/core/client_ops.c.
1715 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1717 * Fixed the silc_idcache_list_* routines to really support
1718 the dynamic list. Fixes a crash. Affected file is
1719 lib/silccore/silcidcache.c.
1721 * Fixed the LIST command reply to really call LIST command's
1722 pending callbacks. Affected file silcd/command_reply.c.
1724 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1726 * Update conn->local_entry->nickname after giving NICK
1727 command. Affected file lib/silcclient/command.c.
1729 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1731 * Added the [pid] option to the silcd configuration file
1733 Affected files: serverconfig.[ch] and silcd.c
1735 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1737 * Save fingerprint in WHOIS command reply in server.
1738 Affected file silcd/command_reply.c.
1740 * Fixed NICK commands pending callback registration.
1741 Affected file lib/silcclient/command.c.
1743 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1745 * Use ++server->cmd_ident when sending commands in server,
1746 instead of random number. Affected file silcd/command.c.
1748 * Fixed GETKEY command reply to call actually GETKEY pending
1749 command callbacks. Affected file silcd/command_reply.c.
1751 * A bit stricter check for nicknames. Check for same nickname
1752 in NICK command also. Affected file silcd/command.c.
1754 * Do not call INFO command everytime client ID changes, only
1755 during first connecting. Affected file lib/silcclient/client.c.
1757 * Set the new nickname only after successful command reply for
1758 NICK command is returned by server. Affected file
1759 lib/silcclient/command.c.
1761 * Remove nicknames from nicklist during server_signoff notify.
1762 Should fix /NAMES bit more. The affected file is
1763 irssi/src/silc/core/silc-channels.c.
1765 * Added `fingerprint' field to the SilcIDListData in the
1766 silcd/idlist.h to hold the fingerprint of the client's
1769 Send the fingerprint of the client's public key in WHOIS
1772 Affected files silcd/command.c, and silcd/idlist.[ch].
1774 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1775 create fingerprint from given data.
1777 * Show the fingerprint of the client's public key in WHOIS.
1778 Affected files irssi/src/module-formats.[ch] and
1779 irssi/src/silc/core/client_ops.c.
1781 * Format the multiple same nicknames also during JOIN and
1782 NICK_CHANGE notifys. Affected file is
1783 lib/silcclient/client_notify.c.
1785 * Do not print error on screen for invalid private message
1786 payload since it can come if someone is sending private
1787 messages with wrong key. Affected file
1788 lib/silccore/silcprivate.c.
1790 * Fixed multiple concurrent /PING crash. Affected file
1791 lib/silcclient/command.c.
1793 * Changed the wrong ID encoding. All IP addresses must be
1794 in MSB first order in encoded format. They were encoded
1795 wrong and was in LSB format. Affected files are
1796 silcd/serverid.c, lib/silcutil/silcutil.c.
1798 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1800 * Call the `connect' client operation through the scheduler
1801 in case of error. Affected file lib/silcclient/client.c.
1803 * Call the `failure' client operation even if the error
1804 occurred locally during a protocol. Affected file is
1805 lib/silcclient/protocol.c.
1807 * Added support of sending LIST command to router from normal
1808 server. This way normal server can get list of all channels
1809 in the network too. Fixed the channel list sending in the
1810 server too. Affected files are silcd/command.c, and
1811 silcd/command_reply.[ch].
1813 * Added silc_server_update_channels_by_server and
1814 silc_server_remove_channels_by_server. They are used during
1815 disconnection of primary router and in backup router protocol.
1816 Affected file silcd/server_util.[ch], silcd/server.c and
1817 silcd/server_backup.c.
1819 * Fixed channel adding to global list in IDENTIFY command
1820 reply in server. Affected file silcd/command_reply.c.
1822 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * If the incoming packet type is REKEY or REKEY_DONE process
1825 that packet always synchronously. Fixes yet another MAC
1826 failed error on slow (dialup) connections. Affected file
1827 lib/silcclient/client.c and silcd/server.c.
1829 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1831 * Call check_version SKE callback for initiator too. Affected
1832 file lib/silcske/silcske.c.
1834 * Implemented fix for security hole found in the SKE that was
1835 fixed in the specification few days back; the initiator's
1836 public key is now added to the HASH value computation.
1837 Added backwards support for the old way of doing it too, for
1838 old clients and old servers. Affected file is
1839 lib/silcske/silcske.c.
1841 * Enabled mutual authentication by default in SKE. If initiator
1842 is not providing mutual authentication the responder will
1843 force it. This will provide the proof of posession of the
1844 private key for responder. The affected files are
1845 lib/silcclient/protocol.c and silcd/protocol.c.
1847 * Do not cache anymore the server's public key during SKE.
1848 We do mutual authentication so the proof of posession of
1849 private key is done, and if the server is authenticated in
1850 conn auth protocol with public key we must have the public
1851 key already. Affected file silcd/protocol.c.
1853 * Added new global debug variable: silc_debug_hexdump. If
1854 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1855 file lib/silcutil/silclog.[ch].
1857 * Fixed compilation warning due to char * -> const char *.
1858 Affected files lib/silcutil/silcnet.h, and
1859 lib/silccore/silcauth.[ch].
1861 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * Fixed CMODE command when new channel key was created. If
1864 the creation failed the old key was removed. Next time giving
1865 same command would crash the server since the old key was
1866 freed already. Affected file silcd/command.c.
1868 * Fixed the silc_server_announce_get_channels to not crash
1869 on reconnect. Affected file silcd/server.c.
1871 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1873 * Added silc_log_set_debug_string function to set a regex
1874 string to match for debug output. Only the function names,
1875 or filenames matching the given debug string is actually
1876 printed. This way it is possible to filter out those debug
1877 strings that user is not interested in.
1879 Fixed a bug in silc_string_regexify.
1881 Affected files lib/silcutil/silclog.[ch], and
1882 lib/silcutil/unix/silcunixutil.c.
1884 * Changed the -d options in both server and Irssi SILC client
1885 to take the debug string as argument. Affected files
1886 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1888 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1890 * Added silc_hash_babbleprint to create a Bubble Babble
1891 Encoded fingerprint. The encoding is developed by Antti
1892 Huima (draft-huima-babble-01.txt), and it creates human
1893 readable strings out of binary data. Affected file
1894 lib/silccrypt/silchash.[ch].
1896 * Print the babble print now in addition of fingerprint as well
1897 in Irssi SILC client. Affected files are
1898 irssi/src/fe-common/silc/module-formats.[ch],
1899 irssi/src/fe-common/silc/core/client_ops.c.
1901 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1903 * Fixed a security problem found in SKE. The initiator's
1904 public key too is now added to the HASH hash value creation
1905 which is signed by the responder to create the SIGN value.
1906 This will prevent anyone in the middle to lie to the responder
1907 about the initiator's public key. If this is done now, the
1908 man in the middle will get caught. Updated the protocol
1911 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Better installation directory handling. Configure module
1914 paths and other paths automatically to example_silc* files
1915 in doc/. A patch by toma.
1917 * Fixed compiler warning from MPI library, and from SILC RNG.
1920 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1921 It can be configured with ./configure. A patch by toma.
1923 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Find correct make to use in prepare-clean. A patch by
1926 toma. Affected file prepare-clean.
1928 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1930 * Added irssi variables use_auto_addr, auto_bind_ip,
1931 auto_bind_port and auto_public_ip.
1933 * Changed the interface for silc_client_send_key_agreement
1934 in lib/silcclient/silcapi.h
1938 irssi/src/silc/core/silc-core.c
1940 lib/silcclient/silcapi.h
1941 irssi/src/silc/core/silc-channels.c
1942 lib/silcclient/client_keyagr.c
1945 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * Added silc_pkcs_public_key_compare to compare two
1948 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1950 * Check that the client who set the founder mode on the
1951 channel is the same client that is giving the founder
1952 mode to itself. It is done by comparing the saved public
1953 key (it is saved even in the authentication is passphrase).
1954 Affected file silcd/command.c.
1956 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1958 * Do not process packet for disconnected socket connection.
1959 Affected file lib/silccore/silcpacket.c.
1961 * Process the DISCONNECT packet through scheduler in the
1962 client library. Affected file lib/silcclient/client.c.
1964 * Fixed the silc_client_packet_parse to not to increase
1965 the packet sequence number if the conn->sock and the
1966 current socket connection is not same. This can happen
1967 for example during key agreement when the conn includes
1968 multiple socket connections (listeners). Affected file
1969 lib/silcclient/client.c.
1971 * The sender of the file transfer request now provides also
1972 the pointer (listener) for the key exchange protocol. If
1973 the listener cannot be created then it sends empty key
1974 agreement and lets the receiver provide the listener.
1976 Added `local_ip' and `local_port' arguments to the
1977 silc_client_file_send. If they are provided they are used,
1978 if not then it will attempt to find local IP address, if
1979 not found or bind fails then the remote client will provide
1982 Affected files are lib/silcclient/client_ftp.c and
1983 lib/silcclient/silcapi.h.
1985 * Extended the FILE SEND command to support defining the
1986 local IP and port for key exchange listener. They are
1987 optional. Affected file irssi/src/silc/core/silc-servers.c.
1989 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1991 * Defined to WHOIS command reply the sending of fingerprint
1992 of the client's public key (if the proof of posession of the
1993 corresponding private key is verified by the server).
1994 Updated to the protocol specification.
1996 * Added support of receiving the client's public key's
1997 fingerprint in command reply in client library. Affected
1998 file is lib/silcclient/command_reply.c, and
1999 lib/silcclient/idlist.[ch].
2001 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2003 * Do not send over 128 chars long nickname to the server
2004 in NICK command. Affected file lib/silcclient/command.c.
2006 * Do not send over 256 chars long channel names to the server
2007 in JOIN command. Affected file lib/silcclient/command.c.
2009 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2011 * Assure that silc_server_close_connection cannot be called
2012 twice for same socket context. Affected file is
2015 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2017 * Send error message to application if opening file for
2018 writing during file transfer fails. Affected file is
2019 lib/silcclient/client_ftp.c.
2021 Remove all file transfer sessions for a client that we're
2022 removing from ID cache.
2024 Affected file is lib/silcclient/client_ftp.c.
2026 * Fixed silc_net_addr2bin to return correct address. Affected
2027 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2029 * Fixed file transfer session removing on signoff notify.
2030 Affected file irssi/src/silc/core/silc-servers.c.
2032 * Added the SilcClientFileError to be returned in the monitor
2033 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2034 Affected file lib/silcclient/silcapi.h.
2036 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2038 * Fixed a crash in silc_client_ftp_free_sessions and
2039 silc_client_ftp_session_free_client. Affected file
2040 lib/silcclient/client_ftp.c.
2042 * Added `disabled' field in the SilcChannelEntry in the server
2043 to indicate if the server entry is disabled. Affected file
2044 silcd/idlist.h, silcd/command[_reply].c.
2046 * SILC server adds now /var/run/silcd.pid everytime it is
2047 started. Affected file silcd/silcd.c.
2049 * Added silc_server_packet_send_clients to send a packet to
2050 the provided table of client entries. Affected file
2051 silcd/packet_send.[ch].
2053 * Fixed a crash in client resolving in client_prvmsg.c in
2054 client library. Affected file lib/silcclient/client_prvmsg.c.
2056 * Do not actually remove the client directly from ID cache
2057 during SERVER_SIGNOFF, but invalidate it. This way we
2058 preserve the WHOWAS info for the client. Affected file
2059 silcd/server_util.c.
2061 * Fixed SERVER_SIGNOFF notify handling in the server. The
2062 server is now able to process incoming SERVER_SIGNOFF notify
2063 for a server that it doesn't even know about. It will remove
2064 the clients provided in the notify. Affected file
2065 silcd/packet_receive.c.
2067 * Check for partial packet in data queue after every packet that
2068 was found from the queue. Return and wait for more data if
2069 there is partial data in queue. Affected file is
2070 lib/silccore/silcpacket.c.
2072 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2074 * Added SilcClietFileError enum to indicate error in
2075 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2076 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2077 Affected files lib/silcclient/silcapi.h and
2078 lib/silcclient/client_ftp.c.
2080 * Check that newsize in silc_buffer_realloc is larger than
2081 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2083 * Added better monitor of file transfers. It now monitors
2084 key agreement protocol during the file transfer too. Added
2085 error reporting too. Affected files
2086 irssi/src/silc/core/silc-servers.c,
2087 irssi/src/fe-common/silc/module-formats.[ch].
2089 * Wrote a help file for FILE command.
2091 * Added silc_rng_global_get_byte_fast to get not-so-secure
2092 random data as fast as possible. Random data is read from
2093 /dev/urandom if available and from the SILC RNG if not
2094 available. It is used in padding generation. Affected file
2095 lib/silccrypt/silcrng.[ch].
2097 * All packets in client library are now processed synchronously.
2098 Optimized packet processing a lot. Affected file
2099 lib/silcclient/client.c.
2101 * All server connection packets are processing synchronously
2102 now in server, to optimize packet processing. Affected file
2105 * Include files are installed now only in Toolkit distribution
2106 if make install is given. Affected files: all Makefile.am's.
2108 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2110 * Assure that silc_client_notify_by_server_resolve does not
2111 resolve the client information multiple times. If it cannot
2112 be found by the first it cannot be found at all. Affected
2113 file lib/silcclient/client_notify.c.
2115 * Fixed WHOWAS command reply calling. Affected file
2116 lib/silcclient/command_reply.c.
2118 * Removed all references to silc_idlist_get_client from the
2119 Irssi SILC client since that call is internal call used by
2120 the library. The Irssi SILC client will use now client
2121 retrieval functions found in silcapi.h.
2123 * Fixed a bug in resolving nickname info before sending
2124 private message. It used freed memory. Affected file
2125 irssi/src/silc/core/silc-servers.c.
2127 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2129 * Assure my_channels statistics cannot go negative in server.
2130 Affected files silcd/server.c, silcd/server_util.c.
2132 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2134 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2136 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * Win32 Toolkit changes. Affected files
2139 win32/silc.dsw, win32/libsilc/libsilc.def,

2146 * Added silc_net_localip to return local host's IP address.
2147 Affected file lib/silcutil/silcnet.[ch].
2149 * If key exchange or rekey protocol is active for a connection
2150 parse all packets syncronously since there might be packets
2151 in packet queue that we are not able to process without first
2152 processing packets before them. Affected file silcd/server,
2153 lib/silcclient/client.c.
2155 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2156 whether library should continue processing the packet.
2157 Affected file lib/silccore/silcpacket.h.
2159 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2160 SilcSFTPMonitorData to SFTP server to monitor various

2192 * Resolve the client info when received private message or
2193 channel message for a client which nickname we don't know.
2194 Affected files lib/silcclient/client_prvmsg.c and
2195 lib/silcclient/client_channel.c.

2203 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2204 is incomplete and is being resolved, it won't be resolved
2207 Make sure also that USERS command reply does not resolve
2208 twice information. Affected file is
2209 lib/silcclient/command_reply.c.
2211 Make sure that silc_client_get_clients_by_list does not
2212 resolve twice same information.
2214 * Check for valid client->id in the silc_server_free_client_data.
2215 Affected file silcd/server.c.
2217 * Fixed /GETKEY nick@server not to crash if the server entry
2218 is not found. Affected file lib/silcclient/command.c.
2220 * Fixed the silc_server_check_cmode_rights to check the
2221 requested modes correctly. Affected file silcd/command.c.

2225 * Better checks for non-printable chars in nick added.
2226 Affected file silcd/command.c.
2228 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2230 * Call the silc_server_udpate_servers_by_server in the
2231 primary router that comes back online in the backup resuming
2232 protocol. Otherwise it routes packets wrong. Affected file
2233 silcd/server_util.[ch], silcd/server_backup.c.
2235 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2238 lib/silcutil/silcbuffmt.[ch].
2240 * Redefined the SILC packet header to include the padding
2241 length. Affected file lib/silccore/silcpacket.[ch].
2243 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2244 length for maximum padding up to 128 bytes). Affected
2245 file lib/silccore/silcpacket.h.
2247 * Removed all backwards support for old 0.5.x MAC thingies.
2248 The SILC packet header change makes it impossible to be
2249 backwards compatible.
2251 * Send the ENDING packet with timeout in the backup resuming
2252 protocol. This is to assure that all routers has connected
2253 to the primary router. Affected file silcd/server_backup.c.
2255 * Changed the RNG to take the first IV from random data. It
2256 used to take it from zero actually. Changed the RNG also
2257 to use /dev/urandom during session. /dev/random is used
2258 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2260 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Changed the SILC packet header to have the first two bytes
2263 (the packet length) encrypted. Affected files aroung the
2264 code tree, lib/silccore/silcpacket.[ch]. Removed the
2265 SilcPacketCheckDecrypt callback. It is not needed anymore
2266 since the silc_packet_receive_process will determine now
2267 whether the packet is normal or special.
2269 * Implemented the unidirectional MAC keys. Affected files
2270 lib/silcske/silcske.c, silcd/protocol.c and
2271 lib/silcclient/protocol.c.
2273 * Implemented the packet sequence number to the MAC computation.
2274 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2275 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2276 lib/silcclient/protocol.c.
2278 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2280 * Allow backup router to announce servers. All servers
2281 announced by backup router are added to the global list
2282 automatically. Update hte server's socket to our primary
2283 router also when backup router announces a server.
2284 Affected file silcd/packet_receive.c.
2286 * Do not update the client->router in the function
2287 silc_server_udpate_clients_by_server if the client is on
2288 global list. We might fail to find any specific server
2289 for locally connected clients and local cell clients. They
2290 should still use the `from' and not `to' as client->router.
2291 This fixes backup router resuming protocol. Affected file
2292 silcd/server_util.c.
2294 * Decrease channel statistics count only if the channel
2295 deletion worked. Affected files are silcd/server.c and
2296 silcd/server_util.c.
2298 * Added silc_server_update_servers_by_server to update origin
2299 of all server entries. Used during backup router protocol.
2300 Affected files silcd/server_util.[ch], silcd/server.c. and
2301 silcd/backup_router.c.
2303 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2304 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2305 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2306 lib/silccrypt/silchmac.c.
2308 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2310 * Assure that router cannot reroute the same channel message
2311 to the sender. Affected file silcd/packet_receive.c.
2313 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2315 * Made better checks that the channel message is not sent
2316 to the router it came from. Affected file is
2317 silcd/packet_send.c. Fixed memory leak too.
2319 * Announce informations for incoming router connection, but
2320 only after checking if it is replaced by backup router.
2321 Affected file silcd/packet_receive.c.
2323 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2325 * Fixed the backup resuming protocol to work in multiple
2326 router environment. Affected file silcd/server_backup.c.
2328 * Route packet only to one router in the function
2329 silc_server_packet_send_to_channel. Affected file is
2330 silcd/packet_send.c.
2332 * Fixed silc_server_send_notify_dest to set the broadcast
2333 flag. Fixed the silc_server_send_notify_topic to actually
2334 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2335 Affected file silcd/packet_send.c.
2337 * Changed the SFTP Filesystem interface. Changed the
2338 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2339 the filesystem operation function. The SilcSFTPFilesystem
2340 is now a context that is allocated by all filesystem allocation
2341 functions and it already includes the operations structure
2342 and filesystem specific context. It is given as argument
2343 now to the silc_sftp_server_start. This made the interface
2344 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2345 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2347 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2349 * Changed the backup router adding and getting interfaces
2350 in the server. The router that will be replaced by the
2351 specified backup router is now sent as argument. Affected
2352 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2355 * Added silc_net_addr2bin_ne to return the binary form of
2356 the IP address in network byte order. Affected files
2357 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2359 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2361 * Check for existing server ID in silc_server_new_server
2362 and in silc_server_connect_to_router_final and remove the
2363 old entry if it exists. Affected file silcd/packet_receive.c,
2366 * Send the channel message always to only one router, either
2367 in upstream or downstream. Affected file is
2368 silcd/packet_send.c.
2370 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2372 * Wrote the definition of the backup resuming protocol to the
2373 protocol specification.
2375 * Removed one redundant channel key generation from normal
2376 server during joining procedure. Removed one redundant
2377 channel key sending from server to router during joining
2378 procedure. Affected file silcd/command.c.
2380 * Made minor bugfixes to the backup router resuming protocol.
2381 Affected file silcd/server_backup.c, server.c.

2385 * Added --disable-asm configuration option. Affected files
2386 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2389 * Implemented the backup resuming protocol that is used to
2390 resume the primary router position in the cell after the
2391 primary router comes back online. Affected files
2392 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2393 and silcd/server_util.[ch].
2395 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2397 * Sleep two (2) seconds after sending QUIT command to server.
2398 Affected file lib/silcclient/command.c.
2400 * Assure that if outgoing data buffer is pending do not force
2401 send any data. Affected file silcd/packet_send.c.
2403 * Assure that if outgoing data buffer is pending do not force
2404 send any data. Affected file lib/silcclient/client.c.
2406 * Implemented the backup router support when the primary router
2407 goes down. The servers and routers can now use the backup
2408 router as new primary router without loosing connectivity.
2410 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2412 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2413 in the server to indicate disabled entry. All data read
2414 from the connection will be ignored and no data is sent
2415 for entry that is disabled. Affected files are
2416 silcd/idlist.h, silcd/server.c.
2418 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2420 * Created SFTP client and server test programs in the
2421 lib/silcsftp/tests directory.
2423 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2425 * Implemented memory filesystem (virtual filesystem) for
2426 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2429 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * Implemented the SFTP (SSH File Transfer Protocol) to the
2432 lib/silcsftp. It includes SFTP client and SFTP server
2435 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * Moved lib/silccore/silcprotocol.[ch] to the
2438 lib/silcutil library.
2440 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2441 take variable argument list pointer as argument. Affected
2442 file lib/silcutil/silcbuffmt.[ch].
2444 * Added silc_buffer_set function that is used to set data
2445 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2446 Affected file lib/silcutil/silcbuffer.h.
2448 * Changed various routines in the core library to use the new
2449 silc_buffer_set instead of allocating new buffer only for
2452 * Added 64-bit value formatting and unformatting support to the
2453 silc_buffer_[un]format routines. Affected file is
2454 lib/silcutil/silcbuffmt.[ch].
2456 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2457 to includes/bitmove.h.
2459 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2461 * Fixed channel user mode saving in client library. Affected
2462 file lib/silcclient/command[_reply].c.
2464 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2466 * Defined the file transfer to the SILC Protocol. Added
2467 new packet type SILC_PACKET_FTP and defined File Transfer
2468 Payload. The mandatory file transfer protocol is SFTP
2469 (SSH File Transfer Protocol). Affected file in addition
2470 of the internet draft is lib/silccore/silcpacket.h.
2472 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2473 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2474 is used as part of backup router protocol when the primary
2475 router of the cell is back online and wishes to resume
2476 the position as primary router.
2478 * Redefined the MAC generation keys in the protocol. The
2479 same key is not used anymore in both direction. Both
2480 direction will now use different keys for sending and
2481 receiving. This fixes a potential security flaw. This
2482 change causes incompatibilities in the protocol.
2484 * Redefined also the MAC computation from the packet.
2485 An packet sequence number is now added to the MAC
2486 computation. This prevents possible replay attacks against
2487 the protocol. This change too causes incompatibilities
2490 Added `sequence' field to the SilcPacketContext to hold
2491 the current sequence number for the packet.
2493 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Added `created' field to the SilcIDListData in the file
2496 silcd/idlist.h to indicate the time when the entry was
2499 * Added `created' field to the SilcChannelEntry too. Affected
2500 file silcd/idlist.h.
2502 * Added `creation_time' aguments to all the announcement functions
2503 in the server. If it is provided then only the entries that
2504 was created after the provided time frame are actually
2505 announced. Affected file silcd/server.[ch].
2507 * The protocol says that the Channel ID's IP address must be
2508 based on the router's IP address. Added check for this in
2509 the silc_server_new_channel when processing incoming New Channel
2510 Payload. Affected file silcd/packet_receive.c.
2512 * Print out the correct version with --version in SILC client.
2513 Affected file irssi/src/silc/core/silc-core.c.
2515 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Fixed WHOWAS command to check for completnes of the client
2518 entry always, not just when the command is coming from client.
2519 Affected file silcd/command.c.
2521 * Added new function silc_server_packet_queue_purge to purge the
2522 outgoing data queue to the network. After the function returns
2523 it is guaranteed that the outgoing packet queue is empty.
2524 Affected file silcd/packet_send.[ch].
2526 * Purge the outgoing packet queue in the rekey protocol's final
2527 callback to assure that all rekey packets go to the network
2528 before quitting the protocol. Affected file silcd/server.c.
2530 * Added silc_client_packet_queue_parse as similar function as
2531 in server to the client library. The affected file is
2532 lib/silcclient/client.c.
2534 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Splitted silcd/server.c and created silcd/server_util.[ch]
2537 for utility functions.
2539 * Added new socket flag SILC_SF_DISABLED to indicate that the
2540 connection is open but nothing can be sent to or received from
2541 the connection. Affected file lib/silcutil/silsockconn.[ch].
2542 The checking for disabled socket is checked in the low level
2543 silc_socket_write and silc_socket_read functions.
2545 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Allow only nicknames and channel names that fits into the
2548 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2550 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2552 * When processing JOIN command reply in server check that if
2553 the channel exists in our global list we'll move it the local
2554 list. Affected file silcd/command_reply.c.
2556 * Fixed the check whether client is joined on the channel already
2557 in JOIN command. Affected file lib/silcclient/command.c.
2559 * Fixed the JOIN command reply to check whether the channel
2560 already exists. Affected file lib/silcclient/command_reply.c.
2562 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Added silc_ske_status_string to map the SKE error numbers
2565 to readable strings. The affected files are
2566 lib/silcske/silcske[_status].[ch].
2568 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Do not show the private channels on the WHOIS channel list
2571 as it is not allowed by the protocol. The affected file is
2574 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Assure that the packet length digged from the actual packet
2577 is something sensible in the silc_packet_decrypt_rest_special
2578 in lib/silccrypt/silcpacket.c.
2580 * Free and NULL the allocated pointer in silc_hmac_alloc if
2581 the HMAC allocation fails. The affected file is
2582 lib/silccrypt/silchmac.c.
2584 * Print the selected security properties to the log files in
2585 the server. Affected file silcd/protocol.c.
2587 * Add SKE's reference counter even if calling the completion
2588 callback manually. Otherwise it goes negative, although it
2589 does not cause any problems. The affected file is
2590 lib/silcske/silcske.c.
2592 * Remove the client entry with short timeout after giving the
2593 KILL command. Affected file lib/silcclient/command.c.
2595 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2596 case all found clients are already disconnected (WHOWAS would
2597 found them) in the server. Affected file silcd/command.c.
2599 * Update the last_receive (time of last data received) to be
2600 updated only when received private or channel message so that
2601 the idle time showed in WHOIS makes more sense.
2603 * Added boolean field `valid' in to the SilcClientEntry in the
2604 client library to indicate whether the entry is valid or not.
2605 This fixes the nickname change bug on channel when changing
2606 the nickname to be same than the old (like nick to Nick) the
2607 nickname formatter doesn't set the new nick anymore to Nick@host.
2608 Affected file lib/silcclient/idlist.[ch].
2610 * Now actually fixed the nickname changing on disconnection.
2611 Added new function silc_change_nick to the Irssi SILC Client.
2612 Affected file irssi/src/silc/core/client_ops.c,
2613 irssi/src/silc/core/silc-nicklist.[ch].
2615 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Check that the public key exists in the GETKEY command before
2618 trying to encode it. Affected file silcd/command.c.
2620 * Print some notifications on received public keys with GETKEY
2621 command in the Irssi SILC Client. Affected files are
2622 irssi/src/fe-common/silc/module-formats.[ch],
2623 irssi/src/silc/core/client_ops.c.
2625 * Use IDENTIFY command to resolve the server information in the
2626 GETKEY command instead of INFO command. Affected file
2627 lib/silcclient/command.c.
2629 * All command reply functions in the client library now calls
2630 the pending command reply callbacks even if an error has
2631 occurred. The server has done this a long time and now it was
2632 time to move the client library to this as well. Now all
2633 errors can be delivered back to the pending command reply
2634 callbacks if necessary. Affected files are
2635 lib/silcclient/command[_reply].[ch].
2637 * Change the nickname on disconnection back to the username
2638 because in reconnect the server will enforce it to it anyway.
2639 Affected file irssi/src/silc/core/silc-servers.c.
2641 * Fixed a config file parsing bug in the Irssi SILC client.
2642 Affected file irssi/src/silc/core/clientconfig.c.
2644 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2646 * When printing the channel mode on JOIN, verify that the
2647 channel key and channel's HMAC are valid. Affected file
2648 irssi/src/silc/core/client_ops.c.
2650 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2652 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2653 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2654 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2656 * Removed channel key rekey task deleting from the function
2657 silc_server_save_channel_key. Affected file silcd/server.c.
2658 Added explicit timeout task context instead that is used to
2659 delete the task if we are registering a new task before the
2660 new task has elapsed.
2662 * When channel key rekey occurs the client library now saves
2663 the old channel key for a short period of time (10 seconds) and
2664 is able to use it in case some is still sending channel
2665 messages encrypted with the old key after the rekey. Affected
2666 file lib/silcclient/[idlist.h|client_channel.c].
2668 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2670 * Added check to the silc_server_new_id_real to not accept
2671 new ID if it is the sender's own ID. Affected file is
2672 silcd/packet_receive.c.
2674 * Assure that we do not announce ourself or the one we've
2675 sending our announcements when we're router and are announcing
2676 servers to our primary router. Affected file silcd/server.c.
2678 * Fixed silc_server_command_identify_check_client to assemble
2679 correct WHOIS packet. It send corrupted WHOIS packet and
2680 caused problem with router to router connections. Affected
2681 file silcd/command.c.
2683 Fixed also silc_server_command_whois_check the same way
2684 as for the IDENTIFY command.
2686 * Added new SilcIDListStatus to the server in the SilcIDListData
2687 structure. The status now includes the current status of
2688 the entry (like registered, resolved etc.). Affected file
2689 silcd/idlist.[ch]. Defined a bunch of different status types
2690 as well. This replaced the old boolean registered field as well.
2692 Added resolve_cmd_ident field to the SilcClientEntry structure
2693 too so that if the entry is for example being resolved so
2694 another command may attach to the same pending command reply
2695 without requiring to resolve the same entry again. This concept
2696 should optimize the WHOIS and the IDENTIFY resolving under
2697 heavy load by taking away unnecessary resolving for entries
2698 that are being resolved already.
2700 Added support for adding multiple pending commands for one
2701 command idenfier. Affected file silcd/command[_reply].[ch].
2703 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2704 before deleting the data. Otherwise the hash table will have
2705 freed data in comparison functions. Affected file is
2706 silcd/command_reply.c.
2708 * Fixed silc_idlist_replace_client_id to add the new entry to
2709 the cache with NULL nickname. Otherwise there will be invalid
2710 memory as the nickname after the nickname is freed. Affected
2711 file silcd/packet_receive.c.
2713 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2714 saved into wrong slots because the previous number of entries
2715 was not taken into account. Affected file silcd/idlist.c.
2716 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2718 * If we are router and we receive JOIN notify to a channel that
2719 does not have any users then notified client is marked as the
2720 channel founder, as it is it. The affected file is
2721 silcd/packet_receive.c
2723 * Added to the extended hash table API's table_del_*ext functions
2724 the destructor as argument too, so that the caller can decide
2725 which destructor to use or whether to use destructor at all.
2726 Affected file lib/silcutil/silchashtable.[ch].
2728 * Fixed ID Cache purging. It actually deleted the entries from
2729 the hash table after the data was freed. The hash table ended
2730 up comparing freed memory. The affected file is
2731 lib/silccore/silcidcache.c.
2733 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2735 * Fixed Irssi SILC client's KILL command's HELP syntax.
2737 * The USERS command now resolves the detailed user information
2738 if the userinfo field is missing. Affected file is
2739 lib/silcclient/command_reply.c.
2741 * Do not print error in silc_file_read if the read file does
2742 not exist. Just silently return NULL. Affected file is
2743 lib/silcutil/silcutil.c.
2745 * Fixed the silc_log_output to not wine about NULL filename
2746 and to not create some bogus " " filename. Affected file is
2747 lib/silcutil/silclog.c.
2749 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2751 * Fixed various printing bugs on the user interface in the
2752 Irssi SILC Client. Minor changes that were forgotten from
2755 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2757 * Fixed the configure.in.pre and the compilation and distribution
2758 environment to support the new autoconf 2.52. That version is
2759 now required to compile the CVS trunk.
2761 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2763 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2764 to generally parse user@fqdn format strings. Affected file
2765 lib/silcutil/silcutil.c.
2767 * Added nickname_format and nickname_force_format fields to the
2768 SilcClientParams structure. The first one defines the format
2769 for the nicknames that the library will enforce if the receives
2770 multiple same nicknames. The second one is boolean value and
2771 can be used to force the library to always enforce the format
2772 to the nicknames regardles whether there are multiple nicknames
2773 or not. This configurable formatting was employed to flexibly
2774 support accessing multiple nicknames from the user interface.
2775 The userinterface can now set the nicknames to what ever format
2776 they prefer. Affected file lib/silcclient/silcapi.h.
2778 Added function silc_client_nickname_format to the file
2779 lib/silcclient/idlist.c. It performs the nickname formatting.
2781 Added new field `hostname´ to the SilcClientEntry context.
2782 It holds the hostname of the client. Affected file is
2783 lib/silcclient/idlist.h.
2785 * Irssi SILC Client sets the nicknames in nick@hostn format.
2786 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2787 irssi/src/silc/core/silc-core.c.
2789 The WHOIS printing now also shows both the real nickname and
2790 the formatted nickname so that user knows how to access the
2791 user if there are multiple same nicknames cached. Affected
2792 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2793 printing formatting too to take the hostname now as a separate
2794 argument. The Affected file is
2795 irssi/src/fe-common/silc/modules-formats.[ch].
2797 * Changed the silc_client_get_clients_local to accept the formatted
2798 nickname as argument. It accepts the real nickname too but the
2799 formatted nickname can be used to find the true entry from
2800 multiple entries. Affected file lib/silcclient/silcapi.h and
2801 lib/silcclient/idlist.c.
2803 * Added nickname_format_parse field to the SilcClientParams.
2804 It is a callback function provided by the application to parse
2805 the nickname out of the formatted nickname string. The library
2806 calls it to get the nickname from the formatted string. Since
2807 the application generally knows better the format of the nickname
2808 string it parses it instead of the library, even though library
2809 encodes the formatted string. If the callback function is not
2810 provided then the library will use the string as is. The
2811 affected file is lib/silcclient/silcapi.h.
2813 * All the nickname strings passed to the client library in
2814 commands are now expected to be formatted nickname strings.
2815 If the command does not support the formatted nickname string
2816 it will assume that the sent string is the actual nickname.
2817 Affected file lib/silcclient/command.c.
2819 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2821 * Added public key authentication support to OPER and SILCOPER
2822 commands in the client library. Affected file is
2823 lib/silcclient/command.c.
2825 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2827 * Changed the get_auth_methdod client operation to be asynchronous.
2828 It can be async if the application resolves the authentication
2829 method from the server during the negotiation. Added new
2830 SilcGetAuthMeth completion callback that the application will
2831 call after resolving the authentication method.
2833 Added function silc_client_request_authentication_method that
2834 the application can use to resolve the authentication method
2835 from the server. Added also SilcConnectionAuthRequest callback
2836 that the library will call after the server has replied. The
2837 application can call this function if it does not know the
2838 current authentication method.
2840 Affected files are lib/silcclient/client.c and
2841 lib/silcclient/silcapi.h.
2843 * The Irssi SILC client now automatically resolves the authentication
2844 method incase any configuration information is not present (and
2845 currently there never is). The affected file is
2846 irssi/src/silc/core/client_ops.c.
2848 * Fixed public key authentication from the client library.
2849 Affected file lib/silcclient/protocol.c. Changed also the
2850 protocol specification about the public key authentication in
2851 the connection authentication protocol. The actual data to be
2852 signed is now computed with a hash function before signing.
2854 * Fixed the public key authentication from the server as well.
2855 Affected file silcd/protocol.c.
2857 * Removed the mlock()'s from the memory allocation routines.
2858 Affected file lib/silcutil/silcmemory.c. The ./configure does
2859 not check anymore for the mlock(). Affected file is
2862 * Fixed USERS command in server to allow the execution of the
2863 command for private and secret channels if the client sending
2864 the command is on the channel. Affected file silcd/command.c.
2866 * Fixed silc_client_get_clients_local to return the clients
2867 count correctly. It could return wrong value. Affected file
2868 lib/silcclient/idlist.c.
2870 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2872 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2873 types. The assembler optimizations seemed not to like 64-bit
2874 data types. The assmebler optimizations thus are now enabled
2875 also for BSD systems as opposed to only enable them for Linux.
2877 * Do not check for threads at all on BSD systems. Affected
2878 file configure.in.pre.
2880 * Removed -n and -h options from the Irssi SILC Client since
2881 they are not used in silc.
2883 * Fixed the prime generation to assure that the first digit
2884 of the generated random number is not zero since our conversion
2885 routines does not like number strings that starts with zero
2886 digit. If zero digit is seen the random number is regenerated.
2887 This caused some corrupted RSA keys when the zero first digit
2888 was met. Affected file lib/silcmath/silcprimegen.c.
2890 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Fixed WIN32 configuration in the ./configure script.
2893 Fixed to include xti.h on environments that has it.
2894 Patches by Carsten Ilchmann and andrew.
2896 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2898 * Changed the silc_id_create_client_id to be collision
2899 resistant. It is now assured that there cannot be created
2900 two same client ID's. I suspect that some weird bugs in
2901 the server were actually caused by duplicate Client IDs.
2902 Affected file silcd/serverid.[ch]. A router receiving
2903 new ID now also assures and informs the sending server
2904 if the ID caused collision.
2906 * Changed the silc_id_create_channel_id to also assure that
2907 there are no collisions.
2909 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Statement about ignoring the Mutual Authentication flag when
2912 performing rekey with PFS was a bit misleading. It is ignored
2913 if it was set in the initial negotiation, it cannot be even
2914 set in the rekey. Fixed in the ke-auth draft. Started the
2915 new versions of the protocol drafts in the doc/.
2917 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2919 * Fixed a bug in silc_client_command_identify_save when saving
2920 new channel information. The channel name was no duplicated
2921 and caused crash on exit. Affected file is
2922 lib/silcclient/command_reply.c.
2924 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2926 * Fixed the getkey command handling in the server. Send just
2927 empty OK reply to the sender if the key could not be fetched
2928 (but everything else was ok, like the key just was not available).
2929 Changed the public key parameter to optional in the protocol
2930 specs so that empty OK reply can be sent. Affected file
2933 Added a message to Irssi SILC client to tell to user if the
2934 server did not return a public key.
2936 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2938 * Fixed a channel key regeneration bug. It registered new
2939 timeout tasks exponentially until all system resources were
2940 used. Affected file silcd/server.c.
2942 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2944 * Added the SILC Document generator to the scripts/silcdoc.
2945 It can be used to generate the Toolkit Reference Manual out
2946 of the source tree. Internally it will also use the RoboDoc
2947 generator now imported in util/robodoc.
2949 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2951 * Added couple of return's in rekey protocol if error orccurred
2952 during the protocol. The execution must be terminated.
2953 Affected file silcd/protocol.c. Also, terminate the protocol
2954 always with timeout.
2956 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * The client's Client ID was created initally from the wrong
2959 nickname (it could have been in format nick@host) in the
2960 silc_server_new_client. Affected file silcd/packet_receive.c
2962 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2964 * Added some SILC_LOG_ERROR's to various error conditions
2965 if client could not be added to ID cache. Affected files
2966 silcd/packet_receive.c and silcd/server.c.
2968 * When client's sock->user_data is freed, NULL also the
2969 client->router and client->connection pointers. Added check
2970 for these pointers being NULL to various places around the
2971 code. Affected file silcd/server.c.
2973 * Added client->data.registered == TRUE checks to various
2974 places around the code to assure that unregistered client's
2975 are not handled when it is not allowed. Affected file
2978 * Added `bool registered' fields to all
2979 silc_idlist_[server|client]_get_* routines to indicate whether
2980 the fetched client needs to be registered or not. Affected
2981 file silcd/idlist.[ch].
2983 * Add your own entry as registered to the ID cache in the
2984 server. Affected file server.c.
2986 * Fixed a bug in silc_server_new_server. The SilcServer was
2987 set as the new server's context instead of SilcServerEntry.
2988 This naturally caused some weird bugs.
2990 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2992 * Do not delete the channel rekey task when adding it
2993 for in silc_server_create_channel_key.
2995 * Changed the silc_server_create_channel_key to return
2996 TRUE or FALSE to indicate the success of the channel key
2999 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Fixed MSVC++ project files and added missing files to
3002 Makefiles under win32/.
3004 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3006 * Do not add TCP_NODELAY flag if the operating system
3007 does not have it defined. Affected files are
3008 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3010 * Fixed buffer overflow from Irssi SILC Client. Affected
3011 file irssi/src/fe-common/core/themes.c.
3013 * Fixed double free in client library in the file
3014 lib/silcclient/client.c when disconnecting from server.
3016 * Applied double free patch from cras to Irssi SILC client.
3017 Affected files irssi/src/core/[modules/expandos].c
3019 * Fixed the disconnection handling to Irssi SILC Client.
3020 The application must call silc_client_close_connection
3021 in ops->connect client operation in case of failure of
3022 the connection. Affected file is
3023 irssi/src/silc/core/client_ops.c.
3025 * Do not set sock->protocol to NULL in the function
3026 silc_client_close_connection after executing the protocol's
3027 final callback since the sock might not be valid anymore.
3028 Affected file lib/silcclient/client.c.
3030 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3032 * Do not enable SILC_THREADS if the linking with libpthread
3033 did not happen. Affected file configure.in.pre.
3035 * Added notion to protocol specification that server must
3036 verify the sent authentication payload with CMODE when
3037 setting the channel founder key. Implemented it to the
3038 server. Affected file silcd/command.c.
3040 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3042 * Added _EXTRA_DIST SILC distribution variable to the
3043 distributions file. It is used to conditionally add extra
3044 files or directories to the specific distribution. Affected
3045 files ./prepare, Makefile.am.pre and distributions.
3047 Removed the `_' from the start of the distribution names.
3050 * Added README.WIN32 for instructions to compile the Toolkit
3053 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3055 * Fixed a double free in disconnection in the server. Affected
3056 file is silcd/server.c.
3058 * Fixed the lib/silcske/groups.c to work now also with GMP
3059 MP library. The string conversion did not work when using
3060 specific base and the base is indicated in the string as well.
3062 * Created win32/ directory which now includes MSVC++ specific
3063 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3064 It will appear only in the toolkit distribution
3066 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3068 * Changed the key material distribution function in case when
3069 the hash output is too short. The data is now concatenated
3070 a bit differently than it used to. Made the change to the
3071 SKE protocol specification.
3073 * Added better GMP detection to configure.in.pre. A patch
3076 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3078 * Fixed a minor bug in SKE that might cause some problem on
3079 some platforms. Affected file lib/silcske/silcske.c.
3081 * Added the cookie checking for initiator in the SKE. It checks
3082 that the responder returns the sent cookie unmodified. The
3083 affected file is lib/silcske/silcske.c. Added new SKE
3084 error type INVALID_COOKIE that can be sent during the
3085 negotiation. Fixed some memory leaks as well.
3087 * Added the "invalid cookie" error message to Irssi SILC client's
3090 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3092 * Added `task_max' field to the SilcClientParams to indicate
3093 the maximum tasks the scheduler can handle. If set to zero,
3094 default values are used. Affected file lib/silcclient/silcapi.h.
3096 * Fixed memory leaks in silc_client_close_connection. Affected
3097 file lib/silcclient/client.c.
3099 * Added silc_client_del_client_entry to client library to free
3100 all memory of given client entry. Affected file is
3101 lib/silcclient/idlist.[ch].
3103 * Added new functions silc_client_del_channel and
3104 silc_client_del_server to delete channel and server entries.
3105 Affected file lib/silcclient/[silcapi.h/idlist.c].
3107 * Removed silc_client_del_client_by_id from silcapi.h.
3109 * Fixed the INFO command to return the server's own info
3110 correctly when querying by Server ID. Affected file is
3113 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3115 * Removed the non-blocking settings in WIN32 code in the
3116 silc_sock_[read/write] and added SleepEx instead. Affected
3117 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3118 of input data is now checked with FIONREAD and ioctlsocket.
3120 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3122 * Call silc_schedule_task_del_by_context in the
3123 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3124 Affected file lib/silccore/silcprotocol.c.
3126 * Call silc_protocol_cancel for active protocols in the
3127 silc_server_close_connection if the funtion
3128 silc_server_free_sock_user_data has not been called.
3129 Affected file silcd/server.c.
3131 * Generic tasks cannot be deleted using the del_by_fd
3132 task deleting function since generic tasks does not match
3133 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3135 * Added a notion to SILCOPER help file that the SILCOPER works
3136 only on router server, not on normal server.
3138 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * Added for WIN32 support for the new scheduler as well.
3141 Affected file lib/silcutil/win32/silcwin32schedule.c.
3143 * Fixed the SHA1 implementation to work on various platforms.
3145 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3147 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3148 API. It is part of the scheduler now. Everything else is
3149 as previously but some functions has changed their names.
3150 Checkout the lib/silcutil/silcschedule.h for the interface.
3151 Updated all applications to use the new interface. Affected
3152 files are lib/silcutil/silcschedule.[ch].
3154 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3156 * Found a bug in the SKE implementation. The HASH value,
3157 specified by the protocol, was not computed correctly. The
3158 public key of the responder was not added to the computation
3159 even though it is mandatory. Affected file lib/silcske/silcske.c.
3160 This unfortunately causes incompatibilities with older
3161 clients and servers.
3163 * Added WIN32 specific network init and uninit functions:
3164 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3165 the Winsock2. Affected file lib/silcutil/silcnet.h and
3166 lib/silcutil/win32/silcwin32net.c.
3168 * Set the socket always to nonblocking mode on WIN32 after
3169 reading data or writing data. Affected file is
3170 lib/silcutil/win32/silcwin32sockconn.c.
3172 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3174 * Fixed various compilation problems under WIN32. Affected
3175 files lib/silcutil/win32/silcwin32thread.c and
3176 lib/silcutil/win32/silcwin32schedule.c.
3178 * Removed all _internal.h #includes from public header
3179 files. Internal headers must never be included from
3182 Removed also the lib/silcske/payload_internal.h file.
3184 * All include files that may be needed (public and some others
3185 included by the public headers) by application developers are
3186 now copied to the ./includes directory. It does not copy any
3187 internal headers. Affected file Makefile.defines.pre and all
3188 Makefile.am's under lib/ and subdirs.
3190 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3192 * Do not change the ~/.silc directory's permissions automatically.
3193 Affected file irssi/src/silc/core/clientutil.c.
3195 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3197 * Do not cancel the protocol in silc_server_close_connection
3198 it might cause recursion. Now cancelled in the function
3199 silc_server_free_sock_user_data. Affected file silcd/server.c.
3201 * Fixed the silc_server_remove_clients_by_server to regenerate
3202 the channel keys correctly finally. Added also new function
3203 silc_server_remove_clients_channels to actually do it.
3204 Affected file silcd/server.c.
3206 * Fixed the silc_server_new_channel to not crash by giving
3207 wrong router to the new channel. Affected file is
3208 silcd/packet_receive.c.
3210 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3212 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3213 which is given as argument to the silc_client_alloc now.
3214 It can be used to configure the client and set various parameters
3215 that affect the function of the client.
3217 * The USERS command in server did not check whether the channel
3218 is private or secret. Affected file silcd/command.c.
3220 * Added new argument to the USERS command in protocol specification.
3221 The USERS command now can take the channel name as argument
3222 as well. Added support for this in client and server and
3223 updated the protocol specs.
3225 * Completed the GETKEY command in client. It can be now used
3226 to fetch also servers public key not only some clients.
3227 Affected files lib/silcclient/command[_reply].c.
3229 * Added silc_client_get_server to return server entry by the
3230 server name. Affected files lib/silcclient/silcapi.h and
3233 * Redefined the IDENTIFY command in protocol specification to be
3234 more generic. It now can be used to query information about
3235 any entity in the SILC Network, including clients, servers and
3236 channels. The query may be based either the entity's name
3237 or the ID. Added support for this in both client and server.
3239 Affected files silcd/command.c and lib/silcclient/command.c
3240 and command_reply.c.
3242 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3243 the _from_client and _from_server functions. Affected file
3246 * Added silc_client_get_channel_by_id_resolve to the file
3247 lib/silcclient/silcapi.h to resolve channel information by
3248 its ID. Added also silc_client_get_channel_by_id that
3249 does not resolve it from the server.
3251 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3253 * Added SilcServerEntry context into the client library
3254 to represent one server. The INFO command now allocates
3255 these to save the resolved server info. For now on the
3256 client library will also keep information about servers,
3257 connected and resolved with INFO.
3259 The INFO command now allocates the SilcServerEntry context
3260 and saves the server info there. The COMMAND_REPLY in
3261 the INFO now returns the parameters to application in
3262 same order as defined in the protocol specification.
3264 The entries are cached in the client->server_cache.
3266 * The INFO command is now issued after received the Client ID
3267 from the server. Affected file lib/silcclient/client.c.
3269 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3270 to the application as the mode changer might be server.
3271 It is guaranteed that NULL is not returned anymore to the
3272 application. Affected file lib/silcclient/client_notify.c.
3274 The ID Type is now also passed to the application so that
3275 it can check whether the returned entry is SilcClientEntry
3278 Added new function silc_client_get_server_by_id to return
3279 the server entry by ID. Affected files are the
3280 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3282 * Do not create the channel in the Irssi SILC Client when issuing
3283 the JOIN command but when received the sucessful JOIN command
3284 reply. Otherwise the channel might get created even though we
3285 could not join it. The Affected file is
3286 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3288 * Fixed a channel joining bug in router. The router must also
3289 check the channel modes, invite and ban lists etc. when serving
3290 the JOIN command sent by normal server. Affected file is
3291 silcd/command.c. The router now resolves the client's
3292 information from the server who sent the JOIN command if it
3293 does not know it, and processes the JOIN command only after
3296 * Changed the SilcCommandCb to take new argument; void *context2.
3297 Affected file lib/silccore/silccommand.h
3299 The second argument in the command callbacks in the server now
3300 includes the SilcServerCommandReplyContext if the command was
3301 called as pending command callback from the command reply.
3302 Otherwise it is NULL. When called as pending the status of the
3303 command reply will be checked and if it was erronous the
3304 error will be sent to the original sender of the command.
3305 This way the client always receives the error messages even
3306 though the server was actually the one who received the error
3307 when it resent the command to router, for example. Affected
3308 files silcd/command[_reply].[ch].
3310 * Fixed sending WHOWAS command's error message to client if
3311 the requested client could not be found. It was missing.
3314 * Changed the CMODE and CUMODE commands reply arguments in the
3315 protocol specification. The Channel ID is now sent in both
3316 of the commands to identify the channel. Implemented this
3317 new feature to the client and server. Affected files
3318 lib/silcclient/command_reply.c and silcd/command.c.
3320 * Made better checks for invite and ban lists in the JOIN
3321 command in server. Affected file silcd/command.c.
3323 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3325 * The server now performs the incoming host IP/DNS lookup
3326 using the silc_socket_host_lookup and thus does not block
3327 the server anymore. Affected file silcd/server.c.
3329 * Completed the multi-thread support for SILC Scheduler in
3330 the lib/silcutil/silcschedule.c.
3332 * Fixed the configure.in.pre to detect the pthread correctly
3335 * Fixed a deadlock in silc_task_queue_wakeup in the file
3336 lib/silcutil/silctask.c.
3338 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3340 * Added new function silc_schedule_wakeup that is used in
3341 multi-threaded environment to wakeup the main thread's
3342 schduler. It needs to be used when a thread adds a new task
3343 or removes a task from task queues. After waking up, the
3344 scheduler will detect the task queue changes. If threads
3345 support is not compiled in this function has no effect.
3346 Implemented the wakeup mechanism to both Unix and WIN32
3347 systems. Affected files are lib/silcutil/silcschedule.[ch],
3348 lib/silcutil/unix/silcunixschedule.c and the
3349 lib/silcutil/win32/silcwin32schedule.c.
3351 * Added new function silc_task_queue_wakeup to wakeup the
3352 scheduler by the specified task queue. Affected file
3353 lib/silcutil/silctask.[ch].
3355 * The silc_socket_host_lookup_start now wakes up the scheduler
3356 after adding the timeout task. Affected file is
3357 lib/silcutil/silcsockconn.c.
3359 * The silc_socket_host_lookup is synchronous now if the threads
3360 support is not compiled in. However, the callback is still
3361 called asyncronously through the scheduler, anyway. Affected
3362 file lib/silcutil/silcsockconn.c.
3364 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3366 * Added new function silc_socket_host_lookup to perform
3367 asynchronous IP and FQDN lookups for the socket connection.
3368 Affected files lib/silcutil/silcsockconn.[ch].
3370 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3372 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3373 that may or may not compile the mutex support in.
3375 Changed the silc_mutex_alloc interface. It allocates the
3376 mutex now to the sent pointer and returns TRUE or FALSE.
3378 Affected file lib/silcutil/silcmutex.h.
3380 * Wrote the SILC Task Queue interface to support multi-threads.
3381 Affected file lib/silcutil/silctask.[ch].
3383 * Wrote the SILC Scheduler to support multi-threads. Affected
3384 file lib/silcutil/silcschedule.c.
3386 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3388 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3389 in lib/silcutil/win32/.
3391 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3393 * Defined SILC Mutex API and SILC Thread API and implemented
3394 them for Unix. Affected files are
3395 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3396 lib/silcutil/unix/silcunixmutex.c and
3397 lib/silcutil/unix/silcunixthread.c.
3399 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3401 * Fixed the silc_server_remove_clients_by_server's channel
3402 key re-generation. The hash table handling was incorrect
3403 and would not work with many channels. Affected file is
3406 * Fixed some memory leaks around the server code.
3408 * Rewrote the silc_server_get_users_on_channel to support IPv6
3409 based Client ID's. Affected file silcd/server.c.
3411 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3412 specification. However, a separate document must be written
3413 to define the detailed signing procedure and the payload
3414 associated with the flag. Defined the flag to the
3415 lib/silccore/silcchannel.h as well.
3417 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3419 * Changed the dynamic tables to static size tables in the
3420 lib/silccrypt/silchmac.c.
3422 * Removed GCC dependencies from the code. A patch by cras.
3424 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3426 * Do not show the error "Error receiving packet bla bla"
3427 in server if it really was not an error (-2 means that reading
3428 is pending). Affected file silcd/server.c.
3430 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3432 * Fixed a possible crash in silc_server_remove_clients_by_server
3433 in silcd/server.c. Fixed there also some memory leaks.
3435 * Fixed the silc_idlist_replace_client_id. It could replace
3436 wrong key in the hash table. Affected file silcd/idlist.c.
3438 * Do not check whether there are global users on the channel
3439 if the channel->global_users is FALSE. Affected functions
3440 silc_server_remove_from_one_channel and
3441 silc_server_remove_from_channels in silcd/server.c. Also,
3442 do not check if the removed client is local as we can be
3443 sure that global client was not removed from the channel
3444 and checking for global users is not needed.
3446 * The silc_server_remove_clients_by_server now re-generates
3447 the channel keys correctly for those channels that had
3448 clients removed from them. Affected file silcd/server.c.
3450 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3452 * Found the reason of random crashes in the server. We weren't
3453 ignoring the SIGPIPE signal (which can be sent in write())
3454 and it crashed the server. Affected file silcd/silcd.c.
3456 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3458 * Assure that sock->user_data is not NULL in the function
3459 silc_server_packet_send in silcd/packet_send.c.
3461 * Disconnect the remote connection if it could not be added
3462 to any ID lists in the server. The affected file is
3465 * Check in silc_server_packet_send[_real/dest] that the
3466 socket is not disconnecting and ignore the data if it is.
3467 Affected file silcd/packet_send.c.
3469 * Define inline to __inline on native WIN32 compilation.
3470 Affected file includes/silcwin32.h.
3472 * Added some explicit type casts for inline code since MSVC
3473 require them. Affected files lib/silcutil/silcbuffer.h,
3474 lib/trq/silcdlist.h and lib/trq/silclist.h.
3476 * Print warning in log files from now on if the packet
3477 decryption fails. Affected file silcd/server.c.
3479 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Changed the `say' client operation's interface to accept
3482 new `type' argument to indicate the type of the message sent
3483 by the library. The application may filter the library's
3484 messages according the type. The affected file is the
3485 lib/silcclient/silcapi.h.
3487 * Added two new functions to lib/silcclient/silcapi.h:
3488 silc_client_del_client and silc_client_del_client_by_id.
3489 Affected file lib/silcclient/idlist.c.
3491 * Moved the clientincludes.h from includes/ to silc/ and
3492 serverincludes.h from includes/ to silcd/.
3494 * The modes for the CMODE and CUMODE are now passed as
3495 uint32 for application with COMMAND_REPLY. The affected
3496 file is lib/silcclient/command_reply.c.
3498 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3500 * /WHOIS without arguments shows client's own information.
3501 Affected file lib/silcclient/command.c.
3503 * Changed PING to not accept any arguments. The specs
3504 says that client can ping only the connected server so
3505 requiring an argument is not needed. Affected file is
3506 lib/silcclient/command.c.
3508 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3510 * Fixed a fatal bug in private message sending and reception
3511 encryption and decryption when using private message keys.
3512 The implementation was incorrect and did not follow the
3513 specification. It causd that some of the message were
3514 lost since it did not use the sending and receiving keys
3515 as the protocol suggests. This has been fixed and will cause
3516 incompatibilities with older clients when sending private
3517 message encrypted with private message keys. Affected files
3518 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3519 and various other in Irssi SILC Client.
3521 Added `responder' boolean argument to the functions
3522 silc_client_add_private_message_key[_ske] to indicate when
3523 the key is added as responder or initiator of the key
3526 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3528 * Removed the silc_ske_check_version function and created
3529 a SilcSKECheckVersion callback. Added also a function
3530 silc_ske_set_callbacks that is now used to set all SKE
3531 callbacks. The callback functions are not given to
3532 the SKE functions anymore, but this function is used to
3535 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3537 * Added `silc_version' argument to the silc_client_alloc
3538 to define the version of the application for the library.
3539 The library will use the version string to compare it
3540 against the remote host's (usually a server) version
3541 string. Affected file lib/silcclient/silcapi.h
3543 * Added the KE protocol context to Key Agreement context
3544 in client library so that we can abort the SKE if it
3545 is in process when we get timeout. Affected file is
3546 lib/silcclient/client_keyagr.c.
3548 * Do not resolve the client ID forever if it returns in the
3549 first time that such client does not exist. This was done
3550 for example with private message. Affected file is
3551 lib/silcclient/client_prvmsg.c.
3553 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3555 * Do not add regex.h for WIN32. The affected file
3556 includes/silcincludes.h.
3558 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3559 not work yet 100%. It generates the DLL's automatically
3560 when compiling with --with-win32 under cygwin.
3562 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * lib/contrib/regex.c is not compiled on WIN32.
3566 * Added silc_net_get_socket_opt function to the
3567 lib/silcutil/silcnet.h.
3569 * Added includes/silcwin32.h for WIN32 specific includes
3572 * Do not use ptime structure or any of the posix process
3573 functions on WIN32 in lib/silccrypt/silrng.c.
3575 * Added silc_gettimeofday to provide generic function
3576 for struct timeval on all platforms. Added the function
3577 to lib/silcutil/silcutil.h.
3579 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3581 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3582 library as they clearly belong there. As a plus side we
3583 can make the actual socket connection routines platform
3586 Added also new generic function silc_socket_read and
3587 silc_socket_write (that used to be silc_packet_[read/write].
3588 The implementation of these are platform specific.
3590 * Added WIN32 specific routines of silc_socket_[read/write]
3591 to lib/silcutil/win32/silcwin32sockconn.c.
3593 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3595 * Added preliminary support for native WIN32 compilation under
3596 cygwin (using the -mno-cygwin option for GCC) to the
3597 ./configure.in.pre. The --with-win32 now prepares the
3598 compilation for native WIN32.
3600 * Rewrote the SILC Scheduler interface in the file
3601 lib/silcutil/silcschedule.h. The scheduler is now context
3602 based and does not have anymore any global static scheduler.
3603 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3604 and created lib/silcutil/win32 directory for WIN32 based
3607 * Added Unix specific network routines to the
3608 lib/silcutil/unix/silcunixnet.c and the old
3609 lib/silcutil/silcnet.c includes now only generic routines.
3611 Added WIN32 specific network routines to the
3612 lib/silcutil/win32/silcwin32net.c.
3614 * Added Unix specific utility functions from the
3615 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3617 * Added WIN32 SILC Scheduler to the file
3618 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3621 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3623 * Do not handle JOIN notify in the server if the target client
3624 is not registered (idata->registered == FALSE). The affected
3625 file is silcd/packet_receive.c.
3627 * Update the nickrec->founder in event_cumode in the Irssi SILC
3628 client. Affected file irssi/src/silc/core/silc-channels.c.
3630 * Fixed the CUMODE_CHANGE notify handling in the server when
3631 server and router are announcing their clients on channels.
3632 Now the mode changes are saved and notified correctly. The
3633 affected file is /silcd/packet_receive.c.
3635 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3636 They really did not replace the cache entry in the ID Cache.
3637 Now they do that. Affected file silcd/idlist.c.
3639 * Fixed the KICK notify handling in the Irssi SILC client to
3640 update the channel records so that the kicked client does not
3641 appear to be on the channel. The affected file is
3642 irssi/src/silc/core/silc-channels.c.
3644 * Always update the conn->current_channel when executing command
3645 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3647 * Fixed the KILL notify handling in Irssi SILC client to remove
3648 the killed client on all channels.
3650 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Fixed the silc_parse_command_line to remove extra spaces
3653 from the start and end of the arguments. Affected file is
3654 lib/silcutil/silcutil.c.
3656 * Cancel and free any active protocol in the function
3657 silc_server_close_connection. Affected file silcd/server.c.
3659 * Cancel and free any active protocol in the function
3660 silc_client_close_connction. Affected file is
3661 lib/silcclient/client.c.
3663 * Do not execute the KILL command for clients that are in
3664 history (ie. they are not in the network). Affected file is
3667 * Fixed KILL notify handling, client does not crash anymore.
3668 Affected file irssi/src/silc/core/silc-channels.c.
3670 * Reduced the default packet buffer size from 2048 to 1024 in
3671 lib/silccore/silcpacket.c.
3673 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3674 counter to the SKE context that is incresed when the SKE library
3675 performs async operation outside the library. If the outside
3676 process frees the SKE context and FREED status will be set
3677 and the library will detect after the sync operation that the
3678 libary is freed. The affected files are
3679 lib/silcske/silcske[_status].[ch].
3681 * Resolve the client entry information in the function
3682 silc_client_channel_message to assure that NULL pointer is not
3683 passed as client entry to the application. */
3685 * Fixed the task timeout calculation to assure that there is
3686 never negative timeouts. The affected file is
3687 lib/silcutil/silcschedule.c.
3689 * Fixed the channel user mode notification sending in server.
3690 It was sent point-to-point to the router (or to server by router)
3691 but it needs to be destined to a channel. The routines now
3692 supports sending the channel user mode notifys to the channels
3693 when announcing clients and channels. Affected files are
3694 silcd/server.c and silcd/packet_receive.c.
3696 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3697 It did not actually replace the old channel entry in the cache.
3698 Affected file lib/silcclient/client_notify.c.
3700 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Fixed a possible crash in silc_packet_send_prepare. It now
3703 assures always that there is enough space in the buffer and
3704 at the tail area of the buffer (for MAC).
3706 Fixed the inbound buffer reallocation in silc_packet_read.
3707 It was old code and did not handle the reallocation correctly.
3710 The affected file is lib/silccore/silcpacket.c.
3712 * Fixed buffer overflow in silc_parse_nickname in the file
3713 lib/silcutil/silcutil.c.
3715 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * make install generates new server keys only if there is not
3720 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3723 Added check that if the NOREPLY is set then we will not send
3724 the away message. This avoids infinite loop of away messages
3725 if both clients are away. The affected file is
3726 lib/silcclient/client_prvmsg.c.
3728 * Fixed client crash if /NICK was given without arguments.
3729 Affected file lib/silcclient/command.c.
3731 * Server does not send the invite list in INVITE command back
3732 to the client if the list was not altered. Added this notion
3733 to the protocol spec as well. Affected file silcd/command.c.
3735 Fixed possible crash in INVITE command by checking the
3736 value of silc_server_get_client_route command.
3738 * Fixed the INVITE notify type handling. The arguments are now
3739 taken in correct order and client does not crash. The affected
3740 file is irssi/src/silc/core/silc-channels.c.
3742 Removed the "Inviting xxx to channel" message from the
3743 client library away and let the application handle it.
3744 Affected file lib/silcclient/command.c. Added that message
3745 to Irssi SILC client's message formats.
3747 * Fixed CMODE command crash in client. It now checks the
3748 amount of arguments correctly and does not crash. The affected
3749 file is lib/silcclient/command.c.
3751 * Do not create new channel automatically in silc_channels_join
3752 but check whether the channel by that name already exists.
3753 Affected file irssi/silc/core/silc-channels.c.
3755 * Do not send the SERVER_SIGNOFF to router if the disconnected
3756 entity was the router. Affected file silcd/server.c.
3758 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3759 SILC client as it was missing from there.
3761 Added the handling of the KICK notify to the Irssi SILC client
3762 as it was missing. Added "you have been kicked" message to
3763 Irssi SILC client's message modules formats.
3765 Added the handing of the KILL notify to the Irssi SILC client
3766 as it was missing. Added the kill message module formats
3769 The affected file is irssi/src/silc/core/silc-channels.c.
3771 * The router did not save the channel mode the server announced.
3772 Affected file silcd/packet_receive.c.
3774 * Fixed a possible crash in INFO command in server. If the
3775 server did not provide the server info it crashed. Affected
3776 file silcd/command.c.
3778 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Fixed the GETKEY command in the server to check also the
3781 global list. Otherwise the GETKEY would not work correctly
3782 in normal SILC server. Affected file silcd/command.c.
3784 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3786 * Fixed GETKEY crash, it crashed if the command did not succseed.
3788 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3791 is now real and not just an macro interface to GMP.
3793 Removed the entire GMP from the source tree and imported new
3794 NSS MPI library instead. Reason for removing GMP is that it is
3795 extremely large and compiles extremely slow. The NSS MPI
3796 is only a few files and compiles in less than 10 seconds.
3797 The speed is also about the same as GMP. The MPI is imported
3798 to lib/silcmath/mpi.
3800 If the system has GMP installed we will still use the GMP.
3801 If it is not then the NSS MPI will be compiled.
3803 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Merged a long nickname (127 characters long) crash bugfix from
3806 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3808 * Merged a freed memory reference bugfix from Irssi CVS tree.
3809 Affected file irssi/src/core/commands.c.
3811 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3813 * Added the server's public key sving and verification to the
3814 server when performing the SKE. This was missing and the
3815 remote server's (or router's) public key was accepted without
3816 checking whether we have it previously or trust it at all.
3817 Affected file silcd/protocol.c.
3819 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Check in the silc_server_timeout_remote if protocol is active
3822 and make sure that the protocol's final callback is called so
3823 that all memory if freed. Affected file silcd/server.c.
3825 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * silc_server_whois_send_reply crashed the server if the nickname
3828 was 127 characters long. Affected file silcd/command.c.
3830 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Added sanity check to the silc_server_new_client. If the hostname
3833 is provided inside username then check that the provided hostname
3834 really is the same as the resolved one. If the hostname was not
3835 resolved then check it from the public key. Affected file is
3836 silcd/packet_receive.c.
3838 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3839 if the server disconnected us and the connection is not valid
3840 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3842 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3843 the library to the lib/silcutil/silcutil.[ch].
3845 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Close log file after open. Affected file
3848 lib/silcutil/silclog.c.
3850 * Check whether sock == NULL in silc_client_send_packet and return
3851 if it is. Affected file lib/silcclient/silcclient.c.
3853 * Check rec->entry == NULL in the Irssi SILC Client before
3854 sending the channel message. Affecte file is
3855 irssi/src/silc/core/silc-servers.c.
3857 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Merged a splitted window bugfix from Irssi CVS tree. The
3860 affected file is irssi/src/fe-text/textbuffer-view.c.
3862 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3863 It did not print nickname.
3865 * Improved the distributions system a bit.
3867 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3870 irssi/src/fe-text/gui-window.c.
3872 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3873 to in-active server. The affected file is
3874 irssi/src/silc/core/client_ops.c.
3876 * Resolve the client in USERS command reply if the entry does
3877 not have username resolved. The affected file is
3878 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3879 command to WHOIS command to really resolve stuff. The USERS
3880 is not used any more in any critical section so WHOIS can
3881 be used even though it might be slower than IDENTIFY.
3883 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3886 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Changed the protocol API a bit more consistent in the
3889 lib/silccore/silcprotocol.[ch].
3891 * Changed the following headers to ROBODoc format:
3893 lib/silccore/silcpayload.h
3894 lib/silccore/silcprotocol.h
3895 lib/silccore/silcsockconn.h
3897 All core library headers are now formatted.
3899 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3901 * Fixed a bug in Irssi SILC client; do not show that you are
3902 server/router operator if you really are not. Affected file is
3903 irssi/src/silc/core/client_ops.c.
3905 * Renamed silc_command_free_payload to silc_command_payload_free.
3906 Affected file lib/silccore/silccommand.h
3908 * Added silcmath.h to include the prototoypes of various routines
3909 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3912 * Changed the following headers to ROBODoc format:
3914 lib/silccore/silcchannel.h
3915 lib/silccore/silccommand.h
3916 lib/silccore/silcid.h
3917 lib/silccore/silcidcache.h
3918 lib/silccore/silcmode.h
3919 lib/silccore/silcnotify.h
3920 lib/silccore/silcpacket.h
3921 lib/silcmath/silcmath.h
3923 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Added checking to the server code not to start the server if
3926 ciphers and stuff are not configured properly. Affected files
3927 silcd/serverconfig.[h] and silcd/server.c.
3929 * Changed the layout of the header files of the public interfaces
3930 in the SILC libraries. The new layout supports ROBODoc
3931 documentation tool (and some others) so that it is easy to create
3932 a library reference manual. All the other headers and source
3933 code must still follow the CodingStyle document. Also source
3934 code must not include these ROBODoc stuffs, only the headers.
3935 Furthermore, all public interface headers must now be named
3936 by using `silc' prefix, example: silcapi.h, silccipher.h.
3937 Some files were renamed due to this. All the other headers
3938 must not be used as public interfaces. I will update the
3939 CodingStyle document later. Changed following headers, so far:
3941 lib/silcclient/silcapi.h
3942 lib/silccore/silcauth.h
3943 lib/silccore/silcprivate.h
3944 lib/silccrypt/silcdh.h
3946 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3950 * Removed silc_client_packet_send_flush from the client library
3951 as it is not needed. Affected file lib/silcclient/client.[ch].
3953 * Added printing of message of unresolved authentication method
3954 to the Irssi SILC client. Added it to the module formats.
3955 Removed the same message from the client library.
3957 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3959 * Added new distribution feature, DISTLABEL. Every distribution
3960 can define own preprocessor label that can be used in the
3961 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3962 file distributions, acconfig.h.pre and prepare.
3964 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Added Makefile.defines_int to include the actual definitions
3967 for Makefile.defines.in. Tested the new distribution system,
3968 created distributions and tested installation.
3970 * Added AWAY message printing to the Irssi SILC client. Added
3971 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3973 * Added SCONNECT command to call the SILC's CONNECT command.
3974 Cannot use CONNECT directly since Irssi uses that internally.
3975 Affected file irssi/src/silc/core/silc-servers.c.
3977 Added ACTION local command. It is same as ME command but takes
3978 the channel as mandatory argument.
3980 Rewrote some of the Irssi's help files to suite for SILC
3983 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Added Makefile.defines[.in] that should for now on be included
3986 in all Makefile.am file in the source tree. That file includes
3987 all common compilation definitions for SILC source tree.
3989 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Minor changes to the ./prepare script to change the package
3992 name according the distribution name to the configure.in.
3994 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3996 * Created new distribution system. Added file `distributions'
3997 that defines all the distributions that can be created out of
3998 the SILC source tree. The ./prepare script now reads that
3999 file to determine how to prepare the distributions. The
4000 first argument to the ./prepare is the name of the distribution
4001 and second is the version of the distribution. If given
4002 without arguments it creates the default (toolkit) distribution
4003 with the default version (defined in ./prepare).
4005 All Makefile.am files that are subject to the distributions
4006 are now named as Makefile.am.pre. These are ./Makefile.am
4007 and lib/Makefile.am. Others may be changed later.
4009 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4011 * Added invite list, ban list, some key management and connection
4012 error message printing to module formats in the Irssi SILC client.
4014 * Added new silc_client_set_away_message to set the away message
4015 that is back to the person who sent private message. The
4016 affected file lib/silcclient/silcapi.h and the
4017 lib/silcclient/client_prvmsg.c.
4019 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Fixed the private message sending in the Irssi SILC client,
4022 added local command KEY to the Irssi SILC client.
4024 Added key management and key agreement message formats to the
4025 irssi/src/fe-common/silc/module-formats.[ch].
4027 Added USERS (alias WHO) printing, server/router operator
4028 indication and LIST command printing to the module formats.
4030 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Fixed channel joining notify handling, cumode notify handling
4033 from Irssi SILC client.
4035 * Added SILC specific module-formats to the Irssi SILC client so
4036 that SILC specific message hilighting, colors etc is possible.
4037 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4039 Added channel mode, channel user mode, actions, notices,
4040 whois and whowas printing to the the module-formats.c.
4042 * Fixed a bug in channel deletion in the server. The channel
4043 is not left to the cache even if the channel founder auth mode
4044 is set when there are no users anymore on the channel. Affected
4045 file silcd/server.c.
4047 * The silc_net_localhost now resolves the entire hostname including
4048 the domain name. Affected file lib/silcutil/silcnet.c.
4050 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Changed the ask_passphrase client operation to be ascynchronous.
4053 It has now a completion callback and a context that the
4054 application must call after it has got the passphrase from
4055 the user. Affected files lib/silcclient/silcapi.h,
4056 lib/silcclient/protocol.c, lib/silcclient/command.c and
4059 Added SilcAskPassphrase callback that the application calls
4060 to deliver the passphrase to the library.
4062 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4063 The public key verification and especially a certificate
4064 verification is asynchronous procedure.
4066 Added new SILC_SKE_STATUS_PENDING status to indicate the
4067 request is pending and a callback will be called to finalize
4070 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4071 indicate that remote end did not send its public key (or
4072 certificate), even though we require it. Added check for this
4073 condition in the SKE. This was a security bug, now fixed.
4075 Defined new SilcSKEVerifyCbCompletion callback that is called
4076 when the verification process is completed.
4078 The affected files lib/silcske/silcske_status.h and
4079 lib/silcske/silcske.[ch].
4081 * Changed the verify_public_key client operation to be async
4082 as well. Defined SilcVerifyPublicKey callback that is used to
4083 indicate the success of the public key verification process.
4085 Changed the server and client to use the new async client
4088 * Changed the Irssi SILC client's internal scheduler to be called
4089 twice as many times as it used to be. As a result the client
4090 should be a bit faster now. Affected file is
4091 irssi/src/silc/core/silc-core.c.
4093 * Added support to Irssi SILC client of asynchronous public key
4094 verification and passphrase inquiry. Affected file is
4095 irssi/src/silc/core/silc-core.c.
4097 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4099 * Do not say "You have left channel %s" in client library.
4100 Moved it to the application. Affected files are
4101 lib/silcclient/command.c and silc/client_ops.c.
4103 * Fixed silc_client_get_clients. Command context was not
4104 duplicated and was freed memory in the callback. Affected
4105 file lib/silcclient/idlist.c.
4107 * Do not say "you are now talking..." on JOIN command in the
4108 client library. The appliation must handle it.
4110 * Do not say ".. changed topic to" in command reply in the
4111 client libary. The application must handle it.
4113 * Fixed TOPIC command sending in the client library.
4115 * Fixed a memory leak in silc_client_command_free in the file
4116 lib/silcclient/command.c.
4118 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4120 * Imported a modified version of Irssi client to the source tree.
4121 The Irssi will be used to create a new client called
4122 Irssi SILC. Imported to irssi/.
4124 Added silc_core_init_finish function to the Irssi. Affected
4125 file irssi/configure.in.
4127 A lot changes in the Makefile.ams around the irssi tree.
4129 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4131 * Do not rehash if the new size is same as the old size of the
4132 hash table, in the silc_hash_table_rehash*. The affected file
4133 lib/silcutil/silchashtable.c.
4135 * Replaced hash_table_del_by_context calls from the server
4136 (when channel->user_list and client->channels) to the
4137 hash_table_del as it is sufficient and faster.
4139 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * Added silc_hash_table_list, silc_hash_table_get and the
4142 SilcHashTableList structure to provide an alternative way to
4143 traverse the hash table. The affected files are
4144 lib/silcutil/silchashtable.[ch].
4146 * Changed the server's idlist routines to use the hash table
4147 routines to optimize the code.
4149 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Replaced the client entry's `channel' list and channel entry's
4152 `user_list' list to hash tables for optimized lookup. Changed
4153 the code to use the hash table interface around the code.
4154 Affected file lib/silcd/idlist.[ch].
4156 * Added `auto_rehash' boolean argument to the function
4157 silc_hash_table_alloc to indicate whether the hash table should
4158 auto-rehash when it thinks is appropriate time. It will
4159 increase the hash table size if the there is twice as much
4160 entries in the table than the size of the table, and will
4161 decrease the size if there are twice as less entries than
4162 the size of the table.
4164 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4168 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * silc_idcache_purge_by_context deletes the entry now by context
4171 as it is supposed to do. Affected file lib/silccore/idcache.c.
4173 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4174 client is not anymore valid (WHOWAS givens the info) and not
4175 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4177 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4179 * Removed the `data' and `data_len' arguments from the ID Cache
4180 interfaces and added `name' argument. ID Cache does not handle
4181 anymore the binary data only a names associated with given ID.
4183 * When hashing a Client ID with silc_hash_id the entire ID is
4184 not hashed anymore, instead only the hash of the Client ID is
4185 hashed. This way we can access the Client ID from the cache
4186 with Client ID but with the hash of the ID (which is a hash of
4187 the nickname) as well without any difference in performance.
4189 Added also silc_idcache_find_by_id_one_ext to do one on one
4190 searching when we have the actual ID. Added also function
4191 silc_hash_client_id_compare. The affected files are
4192 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4194 * When hashing the name associated with a ID it is always done
4195 in lowercase. This way we can access the cache without worrying
4196 about case-sensitivity, even though, for example nicknames are
4199 * Fixed a bug in server with channel message sending. It put
4200 wrong ID type as destination ID. The affected file
4201 silcd/packet_send.c.
4203 * silc_idcache_del_by_context now deletes from all hash tables
4204 by context. Affected file lib/silccore/idcache.c.
4206 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4208 * Changed the client library to use the new ID Cache interface.
4209 Changes around the source tree.
4211 * Added silc_hash_table_rehash_ext to rehash with specific
4212 hash function. Affected file lib/silcutil/silchashtable.[ch].
4214 * Added silc_hash_string_compare to compare two strings in the
4215 hash table. Affected file lib/silcutil/silcutil.[ch].
4217 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4219 * Added new function silc_idcache_del_by_context into the
4220 lib/silccore/idcache.[ch].
4222 * Changed the server's ID list routines to use the new ID Cache
4223 interface. Changes around the source tree.
4225 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Added silc_hash_table_del[_by_context]_ext functions in to the
4228 lib/silcutil/silchashtable.[ch].
4230 Removed silc_hash_table_find_all* routines and added new
4231 silc_hash_table_find_foreach to replace them.
4233 Added silc_hash_table_replace_ext function as extended
4234 replacing function. Separated the simple hash table interface
4235 from the extended hash table interface in the file
4236 lib/silcutil/silchashtable.h.
4238 * Fixed minor bugs and changed it to use some of the new
4239 hash table functions in lib/silccore/idcache.c
4241 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Added new function silc_hash_table_find_all to return all keys
4244 in the hash table by the specified key. As the hash table is
4245 collision resistant it also makes it possible to have several
4246 duplicate keys in the hash table. This function may be used to
4247 find all of the keys from the hash.
4249 Added user_context arguments to the SilcHashFunction,
4250 SilcHashCompare and SilcHashDestructor to deliver user specified
4253 Added new fuctions silc_hash_table_find[_all]_ext to do
4254 extended lookup with specified hash and compare functions and
4255 specified user contexts.
4257 Added new function silc_hash_table_add_ext to add the key
4258 with specified hash function and user context.
4260 Added new function silc_hash_table_foreach to traverse all
4261 entrys in the hash table. Added SilcHashForeach callback
4264 Added new function silc_hash_table_del_by_context to delete
4265 the entry only if the context associated with the key matches.
4267 Affected files are lib/silcutil/silchashtable.[ch].
4269 * Removed silc_hash_[server/client/channel]_id and added just
4270 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4271 silc_hash_id_compare to compare two ID's using as the hash table
4272 comparison function. Added also silc_hash_data to hash
4273 binary data and silc_hash_data_compare to compare it.
4275 * Removed silc_idlist_find_client_by_hash as it is not needed
4276 anymore. Affected file silcd/idlist.[ch].
4278 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4279 to use internally the SilcHashTable. The new ID Cache is a lot
4280 faster than the old one. Some of the ID Cache interface was also
4281 rewritten and obsolete and stupid functions were removed.
4283 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Added entry_count field to the SilcHashTable to keep the number
4286 of the entries in the table. Implemented the function
4287 silc_hash_table_rehash. Added new function
4288 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4290 Fixed a minor bug in silc_hash_table_free.
4292 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4293 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4294 into the lib/silcutil/silcutil.[ch].
4296 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4298 * Implemented a collision resistant hash table into the
4299 lib/silcutil/silchashtable[ch]. See the header and the source
4300 for the SilcHashTable API.
4302 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Merged dotconf version 1.0.2 into lib/dotconf.
4306 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Do not compile anything in lib/silcsim/* if the SIM support
4309 is not enabled. The tree should now compile without problems
4312 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Compiled the SILC under cygwin. Compiled and tested briefly
4315 without problems. More tests needed. The SIMs didn't compile
4318 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4320 * Fixed possible crash in silc_get_username in the
4321 lib/silcutil/silcutil.c.
4323 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Fixed a va_arg in silc/client_ops.c.
4327 * Oops, RC5 routines were named AES and caused some problems
4328 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4330 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * Added new SilcIDIP structure into the lib/silccore/id.h and
4333 replaced the old `ip' fields from all SILC ID's to that type.
4334 This is a step towards IPv6 support.
4336 The silc_id_get_len takes now the ID as an extra argument.
4337 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4338 both IPv4 and IPv6 based ID's.
4340 The affected files are lib/silccore/id.[ch] and other files
4341 around the tree using these routines.
4343 * Removed the ID length arguments in server from various
4344 silc_server_send_notify_* routines -> they are not needed
4347 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4349 * Fixed memory leak in silc_encode_pem_file in the file
4350 lib/silcutil/silcutil.c.
4352 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Check minor version as well in the SKE. Affected files are
4355 silcd/protocol.c and lib/silcclient/protocol.c.
4357 * Added --identifier option to the server so that an identifier
4358 can be when creating the public key for the server. Affected
4359 file is silcd/silcd.c.
4361 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4362 lib/silccrypt/silcpkcs.c.
4364 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Register default ciphers and stuff when using -C option with
4367 the server. Affected file sildc/silcd.c.
4369 * Put back the servers public key filename format, it is better
4370 than the new one. For now, the client keys are saved with the
4371 new filename format. The affected file silc/client_ops.c.
4373 * Implemented the Cipher API for the rest of the ciphers that
4374 did not implement it or implemented it the wrong way.
4376 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Register default ciphers and stuff when using the -S option
4379 in the client. Affected file silc/silc.c. Same also when
4380 creating new key pair with -C option.
4382 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4384 * Fixed the silc_verify_public_key client operation function to
4385 save the public keys differently. The fingerprint is now
4386 used as filename and not the hostname. This way also the
4387 client keys are saved uniquely and not with hostnames. The
4388 affected file is silc/client_ops.c.
4390 * Trimmed the silc_hash_fingerprint function to remove extra
4391 whitespaces from the end of the fingerprint. The affected
4392 file is lib/silccrypt/silchash.c.
4396 * Added silc_cipher_register_default function to register all
4397 default ciphers. It can be used when configuration files
4398 does not exist and the application does not want any specific
4399 ciphers in any specific order.
4401 The SilcDList is now used as silc_cipher_list dynamically
4402 allocated cipher list. Removed the static list all together
4403 and now all ciphers must be allocated to the dynamic list.
4404 The silc_cipher_alloc routine was changed to check only the
4407 All silc_cipher_* routines that used to return int returns
4410 The affected files lib/silccrypt/silccrypt.[ch].
4412 * The same thing was done to silc_hash_* as for silc_cipher_*
4413 routines. Affected files lib/silccrypt/silchash.[ch].
4415 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4416 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4417 Added also silc_pkcs_[un]register[_default] functions.
4418 Removed the data_context from the PKCS API.
4420 * Added silc_hmac_register_default function to register default
4421 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4422 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4423 to unregister all hmacs at once.
4425 * Register the default ciphers, hash functions, PKCSs and HMACs
4426 if client's configuration file does not exist. The affected
4429 * The client did not load the hash functions from the SIM
4430 modules at all. Added support for this. Affected file is
4431 silc/clientconfig.c.
4433 * When decoding public key with silc_pkcs_public_key_decode, check
4434 the supported algorithm only if PKCS are registered. Affected
4435 file lib/silccrypt/silcpkcs.c. The same was done with the
4436 silc_pkcs_private_key_decode.
4438 * Fixed the SILC List routines to keep the list always in order.
4439 It used to change the list's order when traversing the list but
4440 not it preserves the order. Affected file lib/trq/silclist.h.
4442 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Added the client library to use the SilcSocketConnection's
4445 reference counter (by silc_socket_dup) to prevent the bug that
4446 the socket object may be freed underneath async operation.
4448 * The name resolv library checking fixes in the configure.in.pre.
4451 * Created new version of the protocol drafts for future
4452 development. The -03 drafts are the ones that will be changed
4453 in the trunk now and the -02 will remain as they are.
4455 * Send list of CUMODE notifys to the router when announcing
4456 the channel users to the router. Affected file silcd/server.c.
4457 If the router receiving channel founder CUMODE for a channel
4458 that already has channel founder it will send CUMODE notify
4459 to the sender to remove the channel founder rights from the
4460 announced client. Affected file silcd/packet_receive.c.
4462 * The CUMODE notify may now use Server ID as well as the entity
4463 who changes the mode. Updated protocool specs.
4465 * Updated INSTALL and README files.
4467 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * New web pages in the http://silc.pspt.fi. The pages was
4474 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Implemented the [DenyConnectin] config section in the server.
4477 Added silc_server_config_denied_conn to check whether incoming
4478 connection is denied. Affected file silcd/serverconfig.[ch].
4480 * Do not check the ports when checking the incoming configuration
4481 data if the port is 0, meaning any. Affected file is
4482 silcd/serverconfig.c.
4484 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * Fixed buffer overflow in silc_string_compare in the file
4487 lib/silcutil/silcutil.c.
4489 * Fixed double free in silc_server_command_leave in the file
4492 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Fixed the version checking in the server. Affected file is
4497 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Fixed the configuration data fetching when accepting new
4500 connections in the server. Affected file silcd/server.c.
4502 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Added `sender_entry' argument to the function
4505 silc_server_packet_relay_to_channel so that we can check
4506 whether some destination actually belongs to the same route
4507 the sender belongs (ie, we must not resend the packet to the
4508 sender). Affected file silcd/packet_send.[ch].
4510 * Added `servername' field to the SilcClientEntry in the server
4511 to hold the name of the server where client is from. Affected
4512 file is silcd/idlist.h.
4514 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Moved the channel message encrypting in the router betwen
4517 router connections from silc_server_channel_message to the
4518 silc_server_packet_relay_to_channel since we want to check
4519 whether we have anybody channel before encrypting anything.
4520 Affected files silcd/packet_[receive/send].c.
4522 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Fixed the [AdminConnection] server config section to support
4525 multiple entries. Affected file silcd/serverconfig.c.
4527 * Added support into the server to check the validity of the
4528 incoming connection before executing any KE or authentication
4531 * The connection configuration is now saved to the KE and
4532 connection auth protocol contexts and not fetched anymore in
4533 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4535 * The local hosts listenning address and port is also resolved
4536 now when starting the server. We want to have the socket object
4537 to include the real address and port for the listener. Added
4538 new function silc_net_check_local_by_sock into the files
4539 lib/silcutil/silcnet.[ch].
4541 * Fixed a broadcast bug in server -> do not broadcast if we
4544 * Fixed a routing bug. Do not route broadcast packets ever.
4545 Broadcast packets must be processed always and not routed since
4546 they may be destined to some other host than yourself and thus
4547 would get routed without no good reason. Affected file is
4550 * Added function silc_server_config_is_primary_route to check
4551 whether primary router connection has been configured (a router
4552 configuration that we are initiating). If there is not, we
4553 will assume that there is only two routers in the SILC network
4554 and we will use the incoming router connection as our primary
4555 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4557 * Changed the order of the broadcasting. Broadcast _after_ the
4558 packet has been processed not before. Affected file is
4561 * Fixed a [ClientConnection] parsing bug. The port was never
4562 parsed correctly thus resulting to port 0. Affected file
4563 silcd/serverconfig.c.
4565 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4566 argument and did not set the broadcast packet flag. Affected
4567 file silcd/packet_send.c. Fixed same bug in the function
4568 silc_server_send_notify as well.
4570 * If we receive NEW_ID packet for our own ID in the server, ignore
4573 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * Removed the nickname from the Private Message Payload.
4578 Updated the code and the protocol specs.
4580 * Updated protocol specs for submitting to the IETF.
4582 * Tweaked the Random Number Generator a bit. Affected file
4583 lib/silccrypt/silcrng.c. Exported a new function
4584 silc_rng_[global]_add_noise which can be used to add more
4587 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * Do not parse packets with different timeout when protocol
4590 is active -> may cause problem with rekey. Affected file
4593 * When server receives signoff notify it must not create
4594 new channel key if the client is on any channels since the
4595 sender of the signoff notify will create it.
4597 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Added printing of error messages during SKE protocol from the
4600 failure packet sent by server during SKE. Affected file
4603 * Removed the client's failure_callback handling with timeout
4604 and handle it immediately when received.
4606 * The SKE library returned wrong type in SUCCESS and FAILURE
4607 packets. They must be 32 bit MSB not 16 bit MSB.
4609 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Ok, rewrote the logic of the re-key and now it seems to work.
4612 I tested it on high traffic with frequent re-keys without
4613 problems. Added hmac_receive (and renamed hmac to hmac_send)
4614 in SilcClientConnection in lib/silcclient/client.h and
4615 in SilcIDListData in silcd/idlist.h. Also, removed the
4616 SilcPacketParserContext's cipher and hmac fields as they are
4617 not needed anymore and actually caused some problems when
4618 the ciphers and hmac's changed underneath the packet parser.
4620 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * If re-key protocol is active then process the incoming packets
4623 synchronously since we must assure that icoming packets encrypted
4624 with the old key is processed before the new keys is set to
4625 use. This is true other packets than for REKEY packets.
4626 Affected file silcd/server.c. The same was done to client library
4627 as well, affected file lib/silcclient/client.c.
4629 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Fixed bug in client and server to accept the force send if
4632 the packet is send from silc_[server/client]_packet_process
4633 function. Otherwise the packets are never delivered, oops.
4635 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Disable force sending of packets when REKEY protocol is active.
4638 We must assure that no packet is sent directly when rekey is
4639 performed. All packets must be sent through packet queue.
4640 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4641 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4642 function is silc_[server/client]_packet_send_real to check
4645 * Replaced the SIM paths from example config files to
4646 /usr/local/modules. Also, make install creates now
4647 /usr/local/silc/logs directory to hold all the SILC server
4650 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Made the configure.in.pre work on Solaris. Patch by salo.
4654 * Made all ciphers compatible with non-x86 machines. Defined
4655 CBC mode macros into lib/silccrypt/ciphers_def.h.
4657 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Fixed the make install.
4661 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * When MAC computation fails the silc_packet_decrypt returned 0
4664 even though it was supposed to return -1. Fixed this. The
4665 affected file is lib/silccore/silcpacket.c.
4667 * Do not replace the config files in /etc/silc (in make install)
4668 if they already exist. Affected file ./Makefile.am.
4670 * Do not send re-key packets immediately but through packet queue.
4671 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4673 * Changed silc_net_check_host_by_sock to return FALSE if the
4674 IP/DNS could not be resolved. Though, it returns the IP address
4675 now even if it could not resolve it (but returns also FALSE).
4676 Affected file lib/silcutil/silcnet.[ch].
4678 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Added silc_pkcs_decode_identifier to decode the public key's
4681 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4682 Added also silc_pkcs_free_identifier. Added also new context
4683 SilcPublicKeyIdentifier.
4685 * Added -S option to the silc client. It is used to dump the
4686 contents of the specified public key file.
4688 * Changed the PKCS api to return the public key length when
4689 setting the public key.
4691 * Fixed a fatal bug in the public and private key file loading.
4692 Affected file lib/silccrypt/silcpkcs.c.
4694 * Execute the packet parsing for client with zero (0) timeout
4695 if the protocol is active. Affected file silcd/server.c.
4697 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4699 * Made the key generation options to the silcd program. Added
4700 -C option, equivalent to client's option.
4702 * Added new [ServerKeys] config section to the server. It
4703 configures the server's public and private key.
4705 * Defined generic Public Key Payload into the protocol
4706 specification to send specific type of public keys and
4709 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4710 public key or certificate.
4712 * Implemented the GETKEY command to the server and to the
4713 client library and on user interface.
4715 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4717 * Made preliminary `make install' work.
4719 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4721 * Added SilcServerRekey context into silcd/idlist.h.
4723 * Added the PFS support as defined in the specification to the
4724 SKE protocol. Affected files lib/silcske/*.c.
4726 * Added `ske_group' field to the SilcServerRekey context to hold
4727 the number of the SKE group that is used with PFS in re-key.
4728 Affected file silcd/idlist.h.
4730 * Added PFS re-key support to the server. Affected file is
4733 * Added silc_protocol_cancel to cancel execution of the next
4734 state of the protocol. Affected file is
4735 lib/silccore/silcprotocol.[ch].
4737 * Added the re-key support with and without PFS to the client
4738 library. Re-key is performed once in an hour, by default.
4740 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4741 Added silc_client_rekey_callback and silc_client_rekey_final.
4742 Affected files are lib/silcclient/protocol.[ch] and
4743 lib/silcclient/client.[ch].
4745 * Removed the `hmac_key' and `hmac_key_len' fields from the
4746 SilcClientConnection structure; not needed. Affected file is
4747 lib/silcclient/client.h.
4751 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Do not ask whether user wants to use the negotiated private key
4754 for private messages, just use it. Affected file is
4755 silc/local_command.c.
4757 * Added `send_enc_key' and `enc_key_len' fields to the
4758 SilcIDListData structure since they are needed in the re-key
4759 phase. Affected file is silcd/idlist.[ch].
4761 * Implemented the simple re-key protocol into the server.
4762 Affected files silcd/server.c and silcd/protocol.[ch]. The
4763 re-key will be performed once in an hour, by default.
4765 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4766 Added silc_server_rekey, silc_server_rekey_callback and
4767 silc_server_rekey_final.
4769 * Removed Tunneled flag from the protocol. Updated the code
4770 and the specifications.
4772 * Adde `pfs' field to the SilcIDListData to indicate whether
4773 the PFS is to be performed in the re-key. Affected file is
4776 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4778 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4779 int64 of at least the xintXX size. If void * is less that 4
4780 bytes uint32 * will be used. Defined bool as boolean.
4782 * Changed _ALL_ unsigned long and unsigned int to uint32,
4783 unsgined short to uint16 in the source tree.
4785 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4786 not handle clients that has entry->data.registered == FALSE.
4787 They are not in the network anymore. Affected file is
4790 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Implemented the sending of the SERVER_SIGNOFF notify in the
4793 server. Affected file is silcd/server.c.
4795 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4796 Added also silc_notify_payload_encode_args into the
4797 lib/silccore/silcnotify.[ch].
4799 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4800 Affected file silcd/packet_receive.c.
4802 * Implemented the SERVER_SIGNOFF notify handling in the client
4803 library. Affected file lib/silcclient/client_notify.c. Also,
4804 implemnted the printing of the SERVER_SIGNOFF info to the
4805 application. Affected file silc/client_ops.c.
4807 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4808 if the deleting was successful. Affected file silcd/idlist.[ch].
4810 * Added support for public key authentication in the connection
4811 authentication protocol in the client library. Affected file
4812 lib/silcclient/protocol.c.
4814 * Changed the server's silc_idlist_get_clients_by_* interface
4815 to support already allocated array so that new entries may be
4816 added to pre-allocated array. Affected file silcd/idlist.[ch].
4817 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4818 and command replies.
4820 * All command reply functions in the server now calls the
4821 pending command callback even if error occured. This way the
4822 error will be delivered to the client as well. Affected files
4823 silcd/command.c and silcd/command_reply.c.
4825 * Fixed INFO command to return local server's info if no server
4826 was provided. Affected file lib/silcclient/command.c.
4828 * Removed RESTART command for good. Updated the code and the
4831 * Rewrote parts of the task system. It is a bit simpler now.
4832 Removed unsued task priorities. The affected files are
4833 lib/silcutil/silctask.[ch].
4835 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4837 * Moved the USERS printing from the library to the application.
4838 Affected files lib/silcclient/command.c and silc/client_ops.c.
4840 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4844 * Added channel key re-key support. The re-key is perfomed
4845 only by the router and is done once in an hour. Added `rekey'
4846 field to the SilcChannelEntry in the server. Affected files
4847 silcd/server.c and silcd/idlist.h.
4849 * Added silc_task_unregister_by_context into the file
4850 lib/silcutil/silctask.[ch].
4852 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4854 * Added SILC_UMODE_GONE mode to indicate when the client is not
4855 present in the SILC network. Added also support to the local
4856 command AWAY that will set this mode. Added support of showing
4857 "xxx is gone" in WHOIS command. The USERS command shows the
4858 gone status as well.
4860 * Fixed setting server and router operator privileges in the
4861 server's UMODE command. Affected file silcd/command.c.
4863 * Merged the SKE KE1 and KE2 payloads into one payload. The
4864 new KE payload is equivalent to the old KE2 payload.
4866 Cleaned up the SKE Start Payload parsing. It now uses the
4867 simple buffer unformatting to do the parsing. A lot faster
4870 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4871 to the SKE that is used to indicate whether both of the SKE
4872 parties should perform authentication. By default only the
4873 responder performs authentication. By setting this flag also
4874 the initiator must do authentication. By default it is unset
4875 since in normal SKE case, client to server connection, only
4876 the responder should do authentication. When doing SKE between
4877 two clients both should perform authentication. Updated the
4878 code and the protocol specs.
4880 * A little fix to IDENTIFY command in the server. Search the
4881 client first by hash not nickname. Affected file is
4884 * Fixed the silc_client_close_connection to support closing
4885 the client to client connections wihtout deleting too much
4886 data. Affected file lib/silcclient/client.c.
4888 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4889 are received if protocol used to be active but is not anymore
4890 the application would crash due to NULL pointer dereference.
4891 Affected files silcd/server.c and lib/silcclient/client.c.
4893 * Added `hash' field to the SilcClientConnection to include
4894 the hash function negotiated in the SKE protocol.
4896 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4897 to set the channel founder authentication data. A client can
4898 claim the founder rights later by providing the authentication
4899 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4900 This way the channel founder can regain the channel founder
4901 privileges even it is left the channel. This works only on
4902 local server and the client must be connected to the same
4903 server to be able to regain the founder rights. Updated the
4904 protocol specs accordingly.
4906 Added support to the CMODE command in the client to set the
4907 founder auth data. Read the README to see how to set it.
4909 Added support to the CUMODE command to claim the founder
4910 rights. Read the README to see how to do it.
4912 Added support for the founder authentication to the Channel
4913 Entry in the server. Affected file silcd/idlist.h.
4915 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4916 server's CMODE command. Affected file silcd/command.c.
4918 * Added the following new functions into lib/silccore/silcauth.[ch]:
4919 silc_auth_get_method and silc_auth_get_data.
4921 * The server now saves the remote hosts public key to the
4922 SilcIDListData pointer. Affected file silcd/protocol.c.
4924 * The normal server now does not remove the channel entry from
4925 the cache if the founder authentication data is set. It used
4926 to remove it if the founder was the last one on the channel on
4927 the server and left the channel. The auth data is saved and
4928 if the channel is re-joined later the old entry is used with
4929 the old auth data. Affected files silcd/command_reply.c and
4932 * Removed the `pkcs' field from the SilcIDListData structure
4933 in the server; it is not used. Affected file silcd/idlist.h.
4935 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Fixed packet processing on slow links. Partial packets were
4938 never re-processed because the incoming data buffer was cleared
4939 by the application. Application must not directly clear the
4940 sock->inbuf, the packet processing routines handle it. Fixed
4941 this in client library and in server.
4943 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Fixed the WHOIS and IDENTIFY send reply function to really
4946 check whether to send list or just one entry. Affected file
4949 * Cleaned up the LEAVE command's channel key distribution. The
4950 affected file silcd/command.c.
4952 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4953 can enforce the channel mode as well. In that case the ID
4954 includes the ID of the server. The code now enforces the
4955 mode change if the router have different mode than the server.
4957 * The notify client operation with CMODE_CHANGE notify can now
4958 return NULL client_entry pointer if the CMODE was not changed
4959 by client. Application must check for this.
4961 * Added <Server ID> argument to INFO command to support server
4962 info fetching by Server ID.
4964 * Added silc_server_announce_get_channel_users to get assembled
4965 packets of channel users of the specified channel. Affected
4966 file silcd/server.[ch].
4968 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4969 was freed underneath the ID Cache.
4971 * Re-announce clients when the server received CHANNEL_CHANGE
4972 notify from the router. Affected file silcd/packet_send.c.
4974 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4977 crashed since it did not handle the fact that there is no cipher
4978 called "3" and didn't check the error condition. Now fixed.
4980 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4981 flag. It can be used to send message requests.
4983 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * Implemented the RESTART command in the client.
4987 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4988 notice type messages. Added notice printing to the user
4991 * The channel keys are not re-generated if the channel's mode
4992 is PRIVKEY, ie private key on the channel exists. Affected
4993 files silcd/server.c and silcd/command.c.
4995 * Fixed a little bug in channel message delivery when channel
4996 private keys are set in the server. Affected file is
4997 silcd/packet_send.c.
4999 * Changed the setting on channel->on_channel = TRUE from the
5000 silc_client_save_channel_key to the JOIN command reply. The
5001 key payload is not received if the private channel key is set.
5002 Affected file lib/silcclient/command_reply.c and the
5003 lib/silcclient/client_channel.c.
5005 * When the CMODE_CHANGE notify is sent and the channel private
5006 key mode is removed the channel key must be re-generated in
5007 other cells as well. Added this support for the router in the
5008 silcd/packet_receive.c.
5010 * Added new local command NOTICE to send notice message on
5011 channel. Affected file silc/local_command.[ch].
5013 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Added new local command ME to the client. It is used to send
5016 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5017 some action. Affected file silc/local_command.[ch].
5019 * Changed channel_message and private_message client operations
5020 to deliver the message flags to the application. Added also
5021 the `flags' arguments to the silc_client_send_channel_message
5022 and silc_client_send_private_message functions. Affected file
5025 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Redefined the Private Message Payload to support private message
5028 keys and to support the new private message flags. Updated
5029 the protocol specs. Flags makes it possible to have for example
5030 CTCP style messages.
5032 * Added new type SilcPrivateMessagePayload and defined an API
5033 for it in the lib/silcclient/silcprivate.[ch].
5035 * Tested private message private keys successfully. Tested the
5036 private message key set, unset and list commands with the new
5039 * Redefined the Channel Message Payload to include the channel
5040 message flags (equal with private message flags) to support
5041 for example CTCP style messages.
5043 * Defined some of the message (for channel and private message)
5044 flags. Updated the protocol specs and added the flags to the
5045 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5047 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Added SilcKeyAgreementStatus type to the key agreement routines
5050 to indicate the current status and error if one occured.
5051 The status types are defined in the lib/silcclient/silcapi.h.
5053 * Added new local command KEY that is used to set and unset private
5054 keys for channels, set and unset private keys for private messages
5055 with remote clients and to send key agreement requests and
5056 negotiate the key agreement protocol with remote client. The
5057 key agreement is supported only to negotiate private message keys,
5058 it currently cannot be used to negotiate private keys for channels,
5059 as it is not convenient for that purpose.
5061 * Fixed a minor pending callback setting bug in the function
5062 silc_client_get_client_by_id_resolve, now the function works.
5063 Affected file lib/silcclient/idlist.c.
5065 * Added function silc_net_get_local_port to get local bound
5066 port by socket. Added to lib/silcutil/silcnet.[ch].
5068 * Added `sockets' and `sockets_count' fields to the SilcClient
5069 object. They hold the sockets of the listenning sockets in
5070 the client. Listenning sockets may be for example the key
5071 agreement server. Affected file lib/silcclient/client.[ch].
5072 Added functions the silc_client_add_socket and the
5073 silc_client_del_socket. They are exported to the application
5076 * Added ~./silc/clientkeys to support other client's public keys.
5078 * Renamed verify_server_key client operation to verify_public_key
5079 and added one argument to indicate the type of the connection
5080 (server, client etc.).
5082 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * Added silc_server_connection_auth_request to handle the
5085 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5086 silcd/packet_receive.[ch].
5088 * Added silc_server_send_connection_auth_request into the
5089 silcd/packet_send.c to send the connection auth request packet.
5091 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5094 * Fixed the public key authentication in responder side in the
5095 server. The `auth_data' pointer includes the SilcPublicKey
5096 not the path to the public key. Affected file silcd/protocol.c.
5098 * Implemented the public key authentication in the initiator side
5099 in the server. Affected file silcd/protocol.c.
5101 * Removed the [RedirectClient] config section from the server
5102 configuration. Is not needed and I don't want to implement it.
5104 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Cleaned up the CMODE command in the server. It now works
5107 correctly and supports all the modes defined in the protocol.
5108 Affected file is silcd/command.c.
5110 * Added `hmac_name' field to the SilcChannelEntry in the server
5111 to hold the default HMAC of the channel. It can be set when
5112 creating the channel (with JOIN command). Affected files
5115 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5116 type to indicate the change of the current cipher and hmac
5117 on the channel. Client can safely ignore the <cipher> argument
5118 (if it chooses to do so) since the CHANNEL_KEY packet will
5119 force the channel key change anyway. The <hmac> argument is
5120 important since the client is responsible of setting the new
5121 HMAC and the hmac key into use.
5123 * Fixed the CMODE command in the client library as well.
5125 * Tested CMODE command in router environment successfully.
5127 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * Show the version of the remote client (or server) when connecting
5130 to the server. It is logged to the log file. Affected file
5131 is silcd/protocol.c.
5133 * Fixed the KILLED notify handling in the client library. The
5134 client must be removed from all channels when receiving the
5137 Also, do not remove the client entry when giving the KILL
5138 command but when the KILLED notify is received.
5140 * Removed silc_idlist_find_client_by_nickname from the server.
5141 Not needed anymore. Affected files silcd/idlist.[ch].
5143 * Implemented the CHANNEL_CHANGE notify type handling to the
5144 server. Affected file silcd/server.c.
5148 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5150 * Added silc_server_send_notify_invite to send the INVITE
5151 notify between routers.
5153 * Implemented the INVITE command correctly to the server.
5155 * Implemented the INVITE notify type handling in the server.
5157 * Implemented the INVITE command to the client library and on the
5160 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Added function silc_server_get_client_resolve to find the
5163 client entry by ID from all ID lists and then resolve it
5164 (using WHOIS) if it cannot be found. Affected file is
5167 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * Implemented the BAN command to the client library.
5171 * The JOIN command in the server now checks the invite list
5174 * Changed the silc_command_reply_payload_encode_va and the
5175 silc_command_payload_encode_va to support that if argument is
5176 NULL it ignores and checks the next argument. Affected file
5177 lib/silccore/silccommand.c.
5179 * Added silc_server_send_notify_ban to send the BAN notify
5180 type between routers.
5182 * Chaned the silc_notify_payload_encode to support that if
5183 argument is NULL it ignores and checks the next argument.
5184 Affected file lib/silccore/silcnotify.c.
5186 * Tested ban lists in router environment successfully.
5188 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Implemented BAN command to the server, in silcd/command.[ch].
5192 * Removed the BAN and INVITE_LIST modes from the CMODE command
5195 * Added function silc_string_match to regex match two strings.
5196 Affected files lib/silcutil/silcutil.[ch].
5198 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Redefined parts of the SilcChannelEntry in the server to support
5201 the new ban and invite lists.
5203 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * Redefined the INVITE command. The same command can be used to
5206 invite individuals to the channel but also to manage the invite
5207 list of the channel (to add to and remove from the invite list).
5208 Updated the protocol specs.
5210 * Added new command SILC_COMMAND_BAN that can be used to manage
5211 the ban list of the channel. Updated the protocol specs.
5213 * Removed the channel modes: the SILC_CMODE_BAN and the
5214 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5215 in the CMODE command. The equivalent features are now available
5216 using INVITE and BAN commands. Updated the protocol specs.
5218 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5219 in the network about change in the current ban list. The notify
5220 type is not used by the client.
5222 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5223 support the invite lists.
5225 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Added new function silc_string_regexify that converts string
5228 including wildcard characters into regex string that can
5229 be used by the GNU regex library. Added into the file
5230 lib/silcutil/silcutil.[ch].
5232 Added silc_string_regex_combine to combine to regex strings
5233 into one so that they can be used as one regex string by
5234 the GNU regex library. Added into the file
5235 lib/silcutil/silcutil.[ch].
5237 Added silc_string_regex_match to match two strings. It returns
5238 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5240 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Imported GNU regex to the soruce tree into lib/contrib.
5243 Fixed some compiler warning from the regex.c.
5245 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5247 * Fixed MOTD command in the server to work in router environment.
5249 * Fixed the MOTD command in the client library to support
5250 the server argument in the command.
5252 * Added `nickname_len' argument to the silc_idlist_add_client
5253 in the server, as the `nickname' argument may be binary data
5256 * Added silc_idlist_get_channels to return all channels from
5259 * Implemented LIST command to the server. Affected file is
5262 * Implemented the LIST command to the client library and on the
5265 * Added [<user count>] argument to the LIST command reply.
5266 With private channels the user count is not shown.
5268 * Updated TODO and README.
5270 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5272 * The client entry's data.registered must be TRUE even with
5273 global client entry on global client list. The data.registered
5274 is used to check whether the client is anymore in the network,
5275 for example with WHOWAS command so it must be valid.
5277 * Fixed the WHOWAS command in the server. It now actually works
5278 in router environment. Added function into silcd/command_reply.c
5279 silc_server_command_reply_whowas_save.
5281 * Added silc_idlist_purge function to the silcd/idlist.c
5282 to periodically purge the ID Cache.
5284 * Fixed INFO command in the server. It works now in router
5285 environment. Added <server name> argument to the INFO command
5286 reply. Updated the protocol specs.
5288 * Fixed minor bug in silc_idcache_purge to not purge if the
5289 expire value is zero.
5291 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5292 they were buggy because of the WHOWAS information.
5294 * Fixed local command MSG to handle the async resolving of
5295 the remote client properly. It used to fail the first MSG.
5296 Affected file silc/local_command.c.
5298 * Added `data_len' field to SilcIDCache context.
5300 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Update TODO. Todo in commands in the server.
5304 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5307 used by routers as broadcast packet to inform other routers
5308 about the changed user mode.
5310 Implemented the notify handling in the server. Affected file is
5311 silcd/packet_receive.c. Added the function
5312 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5314 * Added new generic Channel Payload and deprecated the New Channel
5315 Payload. The New Channel Payload is now the generic Channel
5318 * Added new argument `mode' to the silc_server_send_new_channel
5319 as it is required in the Channel Payload now.
5321 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5322 and created a new and real SilChannelPayload to represent the
5323 new generic Channel Payload. Implemented the encode/decode
5324 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5326 * Added silc_server_get_client_channel_list to return the list
5327 of channels the client has joined for WHOIS command reply.
5328 Affected file silcd/server.[ch].
5330 * Implemented the channel list sending in the WHOIS command reply
5331 in server and in the client.
5333 Implemented the channel list displaying on the user interface
5334 as well. Affected file silc/client_ops.c.
5336 * Added silc_channel_payload_parse_list to parse list of Channel
5337 Payloads. It returns SilcDList list of SilcChannelPayloads.
5338 Client for example can use this function to parse the list of
5339 channels it receives in the WHOIS command reply. The caller
5340 must free the list by calling silc_channel_payload_list_free.
5341 Affected files lib/silccore/silcchannel.[ch].
5343 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Added one new argument <user mode> to the WHOIS command reply
5346 to return the mode of the user in SILC. Updated the protocol
5349 Implemented it to the server and client.
5351 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5353 * Fixed the mode printing on the user interface on joining.
5354 Affected file silc/client_ops.c.
5356 * Implemented the UMODE command and user modes in general to the
5357 client library and to the user interface.
5359 * Implemented the UMODE command to the server.
5361 * The server now sends UNKNOWN_COMMAND error status if client sends
5362 unknown command. Affected file silcd/command.c.
5364 * All server commands now handle the command identifier the right
5365 way when sending the command reply to the client. The client can
5366 use to identify the command replies with the identifier.
5368 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Added silc_server_get_client_route to resolve the route to
5371 the client indicated by the client ID. Affected file is
5374 * Added silc_server_relay_packet as general function to relay
5375 packet to arbitrary destination. This deprecates functions
5376 like _send_private_message_key, _relay_notify etc. Affected
5377 file is silcd/packet_send.[ch].
5379 Removed silc_server_send_key_agreement,
5380 silc_server_send_private_message_key and
5381 silc_server_packet_relay_notify functions from the file
5382 silcd/packet_send.[ch].
5386 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5387 server. Affected file silcd/packet_receive.[ch].
5389 * Implemented the KILL command to the client. Implemented the
5390 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5391 Affected files lib/silcclient/command[_reply].c and
5392 lib/silcclient/client_notify.c. Implemented the KILL notify
5393 printing in the user inteface.
5395 * Fixed a lot silc_parse_nick memory leaks from the client
5396 library in the file lib/silcclient/command.c.
5398 * Changed the silc_server_send_notify_on_channels's `sender'
5399 argument from SilcSocketConnection to SilcClientEntry to
5400 check the sender as entry and not as connection object and not
5401 to send to the client provided as argument. The affected file
5402 is silcd/packet_send.[ch].
5404 * The notify packets that are destined directly to the client used
5405 to not to be processed by the server. Now changed that and the
5406 server processes all notify packets. After relaying the packet
5407 to the client the notify packet is processed in the server.
5409 * The silc_server_free_client_data now checks whether there is
5410 pending outgoing traffic for the client and purges the data to
5411 the network before removing the client entry.
5413 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5416 an client is killed from the SILC Network. Updated the protocol
5419 Added new function silc_server_send_notify_killed to the
5420 silcd/packet_send.[ch].
5422 * Added function silc_server_packet_relay_notify to relay notify
5423 packets that are destined directly to a client. In this case
5424 the server does not process the notify packets but merely relays
5425 it to the client. Affected file silcd/packet_send.[ch].
5427 Added also silc_server_packet_process_relay_notify to check
5428 whereto relay the notify. Affected file is
5429 silcd/packet_receive.[ch].
5431 * Implemented the KILL command to the server.
5435 * Added the backup schema desgined last fall to the protocol
5436 specs for everyone to see. The specification is in the
5437 *-spec-xx.txt draft and the packet type definitions for the
5438 backup routers is in *-pp-xx.txt draft. Thusly, added also
5439 new packet type SILC_PACKET_CELL_ROUTERS.
5441 * A big security problem in the implementation discovered. The
5442 signoff of an client did not cause new channel key generation
5443 which it of course should've done. The channel keys must be
5444 always re-generated when client leaves (or signoffs) the channel.
5445 The silc_server_remove_from_channels funtion now handles
5446 the channel key re-generation.
5448 * Added `sender' argument to the silc_server_send_notify_on_channels
5449 to not to send the client provided as argument. Affected file
5450 silcd/packet_send.[ch].
5452 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Implemented OPER and SILCOPER commands into the server and
5457 * Added silc_auth_verify and silc_auth_verify_data to verify
5458 the authentication directly from the authentication payload.
5459 It supports verifying both passphrase and public key based
5460 authentication. Affected file lib/silccore/silcauth.[ch].
5462 * Added `hash' field to the SilcIDListData structure. It is the
5463 hash negotiated in the SKE protocol. Affected file is
5466 * Slight redesigning of the SilcAuthPayload handling routines.
5467 Do not send SilcPKCS but SilcPublicKey as argument.
5469 * Implemented the public key authentication support to the
5470 serverconfig. The public key is loaded from the provided path
5471 and saved as authentication data to void * pointer. Thus,
5472 changed the unsigned char *auth_data to void *auth_data;
5474 * Fixed SHUTDOWN command to send the reply before the server
5475 is shutdown. :) Affected file silcd/command.c.
5477 * Fixed fatal bug in CONNECT command. The hostname was invalid
5478 memory and server crashed. Affected file silcd/command.c.
5480 * Fixed fatal bug in CLOSE command. The server_entry became
5481 invalid but was referenced later in the command. Affected file
5484 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Fixed fatal bug in failure packet handling. Server ignored
5487 the failure and thus crashed when it came.
5491 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5494 that the command may be executed only once in (about) 2 seconds.
5495 The old SILC_CF_LAG flag is same but allows command bursts up
5496 to five before limiting.
5498 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5499 server code. Various commands now includes the CF_LAG_STRICT
5500 flag to disallow any kind of miss-use of the command.
5502 * Fixed the silc_buffer_unformat to not to allocate any data
5503 if the length of the data is zero. It used to allocate the
5504 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5506 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Changed the format of AdminConnection configuration section
5509 in the server. Added username of the admin to the format.
5510 Affected files silcd/serverconfig.[ch].
5512 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5513 to return admin configuration data by host, username and/or
5516 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Implemented WHOWAS command to the server. Added the functions:
5520 silc_server_command_whowas_parse,
5521 silc_server_command_whowas_send_reply,
5522 silc_server_command_whowas_from_client and
5523 silc_server_command_whowas_from_server
5525 * Added <Client ID> argument to the WHOWAS command reply. Updated
5526 the protocol specs accordingly.
5528 * Implemented WHOWAS command and command_reply to the client
5531 Implemented the WHOWAS printing on the user interface.
5533 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Added new argument to the WHOWAS command reply, the real name.
5536 It is an optional argument. Updated the protocol specs.
5538 * Added SilcIDCacheDestructor callback that is registered when
5539 the SilcIDCache is allocated. The callback is called when
5540 an cache entry in the ID Cache expires, or is purged from the
5541 cache. Added into lib/silccore/idcache.[ch].
5543 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5544 to destruct the client entries when the cache entry expires.
5545 Other ID Cache's in server and in the client library ignores
5548 * If the ID Cache entry's `expire' field is zero then the entry
5549 never expires. Added boolean `expire' argument to the
5550 silc_idcache_add function in the lib/silccore/idcache.[ch].
5551 If it is TRUE the default expiry value is used.
5553 * Added silc_server_free_client_data_timeout that is registered
5554 when client disconnects. By default for 5 minutes we preserve
5555 the client entry for history - for WHOWAS command.
5557 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5559 * Added support to the server to enforce that commands are not
5560 executed more than once in 2 seconds. If server receives
5561 commands from client more frequently, timeout is registered
5562 to process the commands. Affected file silcd/command.c.
5563 Added new function silc_server_command_process_timeout.
5565 * Changed NICK_NOTIFY handling in client library to check that
5566 if the client's nickname was changed, so there is no need to
5567 resolve anything from the server.
5569 * Removed error printing from the WHOIS and IDENTIFY commands.
5570 If error occurs then it is ignored silently in the client library.
5571 The application, however, may map the received error to
5572 human readable error string. The application currently maps
5573 the NO_SUCH_NICKNAME error to string.
5575 * Made the command status message public to the application. Moved
5576 them from lib/silcclient/command_reply.c to
5577 lib/silcclient/command_reply.h. The application can map the
5578 received command status to the string with the
5579 silc_client_command_status_message function.
5581 * Added check to the server to check that client's ID is same
5582 as the Source ID in the packet the client sent. They must
5585 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5587 * Added dist-bzip hook to the Makefile.am to make bzip2
5588 compressed distributions.
5590 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Server now enforces the maximum length for the nickname and
5593 the channel as protocol specification dictates. 128 bytes for
5594 nickname and 256 bytes for channel name.
5596 * Moved the WHOIS printing to the application. The client libary
5597 does not print out the WHOIS information anymore, the application
5598 must do it. Renamed silc_client_command_reply_whois_print to
5599 the silc_client_command_reply_whois_save.
5601 The client's idle time is also sent to the application now, and
5602 the idle is shown on screen.
5604 * Added silc_client_command_reply_identify_save to save the
5605 received IDENTIFY entries.
5607 * Do not check for channel private keys in message sending and
5608 reception if the channel does not have the PRIVKEY mode set.
5609 Affected file lib/silclient/client_channel.c.
5611 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5613 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5614 just surfaced after chaning the JOIN procedure.
5616 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Added silc_client_get_clients_by_list to get client entries
5619 from Client ID list, that is returned for example by JOIN
5620 and USERS command replies. The application should use this
5621 function for example when JOIN command reply is received to
5622 resolve the clients already on the channel (library does not
5623 do that anymore as USERS command reply is not used in the JOIN
5624 procedure anymore). Affected files lib/silcclient/silcapi.h and
5625 lib/silcclient/idlist.c.
5627 * JOIN command reply and USERS command reply returns now SilcBuffer
5628 pointers instead of unsigned char pointers when returning
5629 the client list and mode list.
5631 * Added <Client ID> argument to the JOIN command reply, mainly
5632 for the server to identify for which client the command was
5633 originally sent. Updated protocol specs accordingly.
5635 * Added SilcDlist private_key pointer to the SilcChannelEntry
5636 in the client to support the channel private keys. Affected
5637 file is lib/silcclient/idlist.h.
5639 * Added SilcChannelPrivateKey argument to the function
5640 silc_client_send_channel_message so that application can choose
5641 to use specific private ke if it wants to. If it is not provided,
5642 the normal channel key is used, unless private keys are set.
5643 In this case the first (key that was added first) is used
5644 as the encryption key.
5646 * Implemented the support for channel private key handling.
5647 Implemented the following functions:
5649 silc_client_add_channel_private_key,
5650 silc_client_del_channel_private_keys,
5651 silc_client_del_channel_private_key,
5652 silc_client_list_channel_private_keys and
5653 silc_client_free_channel_private_keys
5655 Affected file lib/silcclient/client_channel.c.
5657 * Added the support for the private keys in the channel message
5658 sending and encryption and in the message reception and
5659 decryption. Affected funtions are
5660 silc_client_send_channel_message and silc_client_channel_message.
5662 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Added SKE's key verify callback to the client library's
5665 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5667 * Removed the statement that server (or router) must send USERS
5668 command reply when joining to the channel so that the client
5669 knows who are on the channel. Instead, the client list and
5670 client's mode list is now sent in the JOIN command reply to the
5671 client who joined channel. This is better solution.
5673 * Added function silc_server_get_users_on_channel and function
5674 silc_server_save_users_on_channel to the silcd/server.[ch].
5676 * Removed function silc_server_command_send_users from the
5679 * Do not show topic on the client library anymore. The topic is
5680 sent in the command reply notify to the application and the
5681 application must show the topic now.
5683 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Added client searching by nickname hash into the IDENTIFY and
5686 WHOIS commands in the server as they were clearly missing from
5687 them. Affected file is silcd/command.c.
5689 * Fixed a bug in private message receiving in the client library.
5690 The remote ID was freed and it wasn't supposed, now it is
5693 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5695 * Minor fix to the channel payload; allocate the data area, as it
5696 needs to be of specific length.
5698 * If the key agreement port is zero then the operating
5699 system will define the bound port. Affected files are
5700 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5702 * Added new function silc_channel_payload_decrypt into the file
5703 lib/silccore/silcchannel.[ch].
5705 * Moved the channel message etc, check from silc_packet_decrypt
5706 to applications. The library calls now a generic
5707 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5708 when the packet is either normal or special. This was done to
5709 allow more wide range of checking that was not allowed when
5710 the code was in library. Now applications can do virtually any
5711 checks to the packet and return to the library the decision how
5712 the packet should be processed. Affected files are
5713 lib/silccore/silcpacket.[ch].
5715 Added silc_server_packet_decrypt_check to the server and
5716 silc_client_packet_decrypt_check to the client library.
5718 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5719 to send with specified source and destination information.
5721 * Channel message delivery between routers was broken after the
5722 channel key distribution was fixed earlier. The channel key
5723 was used be to distributed to other routers as well which is not
5724 allowed by the protocol. Now this is fixed and channel keys
5725 really are cell specific and the channel message delivery between
5726 routers comply with the protocol specification.
5728 * Fixed various commands in server to check also the global list
5729 for the channel entry and not just the local list. The affected
5730 file silcd/command.c.
5732 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5734 * Added assert()s to buffer formatting and unformatting routines
5735 to assert (if --enable-debug) when error occurs. Affected
5736 file: lib/silcutil/silcbuffmt.c.
5738 * Changed to auto-reconnect to check whether the remote host is
5739 router and register the re-connect timeout if it is. It used
5740 to check that whether we are normal server, but router must do
5741 auto-reconnect with another router as well. Affected file
5744 * Removed the [<key len>] option from CMODE command as the cipher
5745 name decides the key length, nowadays. See the defined ciphers
5746 from the protocol specification.
5748 * Added [<hmac>] option to the CMODE command to define the HMAC
5749 for the channel. Added SILC_CMODE_HMAC channel mode.
5751 * Added [<hmac>] option for the JOIN command so that user can
5752 select which HMAC is used to compute the MACs of the channel
5755 * Added Hmac field to the Channel Message Payload. The integrity
5756 of plaintext channel messages are now protected by computing
5757 MAC of the message and attaching the MAC to the payload. The
5758 MAC is encrypted. Now, it is clear that this causes some
5759 overhead to the size of the packet but rationale for this is that
5760 now the receiver can verify whether the channel message decrypted
5761 correctly and also when private keys are set for the channel the
5762 receiver can decrypt the packet with several keys and check from
5763 the MAC which key decrypted the message correctly.
5765 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5766 lib/silccrypt/silccipher.[ch].
5768 * Added silc_hash_len to return the digest length into the
5769 lib/silcrypt/silchash.[ch].
5771 * Rewrote parts of Silc Channel Payload interface in the
5772 lib/silccore/silcchannel.[ch]. The encode function now also
5773 encrypts the packet and parse function decrypts it.
5775 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5777 * Fixed a minor formatting bug in the SKE's key material processing.
5778 It actually might have processed the keys wrong way resulting
5781 * Redefined the mandatory HMAC algorithms and added new algorithms.
5782 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5783 and hmac-md5 truncated to 96 bits. The mandatory is now
5784 hmac-sha1-96. Rest are optional (including the one that used
5785 to be mandatory). Rationale for this is that the truncated HMAC
5786 length is sufficient from security point of view and can actually
5787 make the attack against the HMAC harder. Also, the truncated
5788 HMAC causes less overhead to the packets. See the RFC2104 for
5791 * Added new [hmac] configuration section. The SKE used to use
5792 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5793 is of course wrong. The official names that must be proposed in
5794 the SKE are the ones defined in the protocol specification
5795 (hmac-sha1-96 for example). The user can configure any hmac
5796 using any hash function configured in the [hash] section. At
5797 least, the mandatory must be configured.
5799 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5801 * Added HMAC list to the SKE proposal list. It has now both
5802 hash algorithm list and HMAC list. This makes the protocol
5803 incompatible with previous versions. The SKE now seems to work
5804 the way it is supposed to work, for the first time actually.
5806 * Defined plain Hash algorithms to the protocol specification.
5809 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * Implemented support for key agreement packets into the server.
5812 Added functions silc_server_key_agreement and
5813 silc_server_send_key_agreement. Other than these functions,
5814 server has nothing to do with this packet.
5816 * Added support for private message key packets into the server.
5817 Added functions silc_server_private_message_key and
5818 silc_server_send_private_message_key.
5822 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5823 called in the protocol's final callback instead in the END
5824 protocol state. This makes a little more sense and in the same
5825 time in client we can use the same protocol routines for normal
5826 key exchange and to key agreement packet handling as well.
5828 * Added to both client's and server's KE protocol context the
5829 SilcSKEKeyMaterial pointer to save the key material. We will
5830 bring the key material to the protocol's final callback by doing
5831 this. The final callback must free the key material.
5833 * Added SKE's packet_send callback into client's KE protocol
5834 context so that the caller can choose what packet sending function
5835 is used. This way we can use different packet sending when
5836 doing normal SKE when doing key agreement packet handling (in
5837 the key agreement packet handling we do not want to encrypt
5840 * Implemented the responder side of the key agreement routines
5841 in the client. The client can now bind to specified port and
5842 accept incoming key negotiation. The key material is passed
5843 to the application after the protocol is over.
5845 * Implemented the processing of incoming Key Agreement packet
5846 in the client. Added function silc_client_key_agreement to
5849 * Implemented the intiator side of the key agreement routines
5850 in the client. The client can now initiate key agreement with
5851 another remote client. The key material is passed to the
5852 application after the protocol is over.
5854 * Created client_keyagr.c to include all the key agreement
5857 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5858 SILC_TASK_CALLBACK except that it is not static.
5860 * Created client_notify.c and moved the Notify packet handling
5861 from the client.[ch] into that file.
5863 * Created client_prvmsg.c and moved all private message and
5864 private message key routines from the client.[ch] into that file.
5866 * Create client_channel.c and moved all channel message and
5867 channel private key routines from the client.[ch] into that file.
5869 * Changed silc_client_get_client_by_id_resolve to resolve with
5870 WHOIS command instead of IDENTIFY command, in the file
5871 lib/silclient/idlist.c.
5873 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Implemented the SKE's responder side to the Client library.
5877 * When FAILURE is received to the protocol do not trust it
5878 blindly. Register a timeout to wait whether the remote closes
5879 the connection as it should do it, only after that process the
5880 actual failure. This was changed to both client and server.
5882 * Added client_internal.h to include some of the structures
5883 there instead of client.h in lib/silcclient/.
5885 * Added function silc_task_unregister_by_callback to unregister
5886 timeouts by the callback function.
5888 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Some "Incomplete WHOIS info" errors has been appearing on the
5891 log files. Took away the entry->userinfo check from WHOIS
5892 reply sending. The entry->userinfo is now " " if client did not
5893 provide one. I thought this was fixed earlier but something
5894 is wrong still. Let's see if the error still appears.
5896 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Fixed a minor bug in the login when the channel key is
5899 re-generated in the server. It used to generate the key in
5900 wrong order and thus caused problems in the channel traffic.
5902 * Fixed a minor bug in channel key distsribution after
5903 KICK command. The key was not sent to the router even though
5906 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Added silc_ske_process_key_material_data as generic routine
5909 to process any key material as the SILC protocol dictates. The
5910 function is used by the actual SKE library but can be used by
5911 applications as well. This relates to the private message keys
5912 and the channel private keys since they must be processed the
5913 same way the normal SILC session keys. The protocol dictates
5914 this. Affected files: lib/silcske/silcske.[ch].
5916 Added also silc_ske_free_key_material to free the
5917 SilcSKEKeyMaterial structure.
5919 * Defined silc_cipher_set_key function to set the key for
5920 cipher without using the object's method function. The affected
5921 files: lib/silccrypt/silccipher.[ch].
5923 * Implemented silc silc_client_add_private_message_key,
5924 silc_client_add_private_message_key_ske,
5925 silc_client_del_private_message_key,
5926 silc_client_list_private_message_keys and
5927 silc_client_free_private_message_keys functions in the
5930 Added functions silc_client_send_private_message_key to send
5931 the Private Message Key payload and silc_client_private_message_key
5932 to handle incoming Private Message Key payload.
5934 * Added Cipher field to the Private Message Key payload to set
5935 the cipher to be used. If ignored, the default cipher defined
5936 in the SILC protocol (aes-256-cbc) is used.
5938 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Removed lib/silcclient/ops.h file.
5942 Redefined parts of the SILC Client Library API. Created new
5943 file silcapi.h that deprecates the ops.h file and defines the
5944 published Client Library API. Defined also private message key
5945 API and channel private key API into the file.
5947 This is the file that the application must include from the
5948 SILC Client Library. Other files need not be included by
5949 the application anymore.
5951 * Added new key_agreement client operation callback and also
5952 defined the Key Agreement library API for the application.
5954 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5957 is used by clients to request key negotiation between another
5958 client in the SILC network. If the negotiation is started it
5959 is performed using the SKE protocol. The result of the
5960 negotiation, the secret key material, can be used for example
5961 as private message key.
5963 Implemented the Key Agreement payload into the files
5964 lib/silccore/silauth.[ch].
5966 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Redefined ciphers for the SILC protocol. Added some new ciphers
5969 and defined the key lengths for the algorithms. Changed the
5970 code accordingly. The default key length is now 256 bits.
5972 * Fixed SKE key distribution function silc_ske_process_key_material
5973 when the key length is more than 128 bits. The default key
5974 length in SILC is now 256 bits.
5976 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5977 to indicate unsupported algorithm.
5979 * Renamed rijndael.c to aes.c and all functions as well.
5981 * Fixed a long standing channel key setting bug in client library.
5982 Weird that it has never surfaced before.
5984 * Fixed bug in channel deletion. If the entire channel is removed
5985 then it must also delete the references of the channel entry
5986 from the client's channel list as the client's channel entry and
5987 the channel's client entry share same memory.
5989 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * Implemented CONNECT and SHUTDOWN commands in the client.
5993 * Implemented CLOSE command to the client.
5995 * Added the function silc_idlist_find_server_by_name into the
5996 files silcd/idlist.[ch].
5998 Added the function silc_idlist_find_server_by_conn into the
5999 files silcd/idlist.[ch].
6001 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6003 * DIE command was renamed to SHUTDOWN. Updated the both code
6006 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6007 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6009 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6012 * Added function silc_server_create_connection function to create
6013 connection to remote router. My server implementation actually
6014 does not allow router to connect to normal server (it expects
6015 that normal server always initiates the connection to the router)
6016 so the CONNECT command is only good for connecting to another
6019 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6021 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6022 or some other client was kicked from the channel.
6024 Implemented the handling of the notify type to both client
6027 Implemented silc_server_send_notify_kicked to send the KICKED
6028 notify. It is used to send it to the server's primary router.
6030 * Implemented the KICK command into server and client.
6032 * Added `query' argument to the silc_idlist_get_client function
6033 to indicate whether to query the client from server or not if
6036 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6037 to indicate that the client is not channel founder.
6041 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6043 * Removed the rng context from SilcPacketContext structure and
6044 changed that the packet routine uses the Global RNG API.
6046 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6048 * Added support for quit message that client can "leave" on the
6049 channel when it quits the SILC. It is ditributed inside the
6050 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6052 Added silc_server_free_client_data that will take the
6053 signoff message as argument.
6055 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6057 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Updated parts of the protocol specification to keep it up
6062 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6064 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6065 payloads in one packet.
6067 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6068 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6069 use now the new List flag.
6071 * Also deprecated the following packet types: REPLACE_ID,
6072 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6074 * Added list support for Notify packet in server.
6076 * Added silc_server_send_notify_channel_change to send the
6077 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6078 the silc_server_send_replace_id.
6080 * Added silc_server_send_notify_nick_change to send the
6081 NICK_CHANGE notify type. Deprecates the function
6082 silc_server_send_replace_id.
6084 * Added silc_server_send_notify_join to send the JOIN notify type.
6085 Deprecates the function silc_server_send_new_channel_user.
6087 * Added silc_server_send_notify_leave to send LEAVE notify type.
6088 Deprecates the function silc_server_send_remove_channel_user.
6090 * Added silc_server_send_notify_cmode and
6091 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6092 types. Deprecates the silc_server_send_set_mode function.
6094 * Added SERVER_SIGNOFF notify type to indicate that server has
6095 quit. This means that all clients on the channel from that
6096 server will drop. This can be also used when netsplit happens.
6098 Deprecated REMOVE_ID packet type since it is not needed anymore
6101 Added silc_server_send_notify_server_signoff to send the
6102 SERVER_SIGNOFF notify type. Deprecates the function
6103 silc_server_send_remove_id.
6105 Added also silc_server_send_notify_signoff to send the
6106 SIGNOFF notify type.
6108 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6109 SILC protocol from this day on. Changed the protocol
6110 specification as well.
6112 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6113 notify type. It is used between routers to notify about
6114 topic changes on a channel.
6116 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6119 * Partly updated the protocol specification to comply with the
6120 changes now made. It is still though a bit outdated.
6122 * The JOIN notify type now takes one extra argument <Channel ID>.
6123 The packet used to be destined to the channel but now the
6124 JOIN type may be sent as list thus it is impossible to
6125 destine it to any specific channel. By adding this argument
6126 it is again possible.
6128 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Added CREDITS file. The CHANGES and CREDITS file will appear
6131 in the distribution as well.
6133 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6136 types in the server's silcd/packet_receive.c.
6138 * Implemented CMODE and CUMODE to work in router environment.
6140 * Fixed minor encoding and decoding buglet from the
6141 lib/silccore/silcmode.c.
6143 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6146 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6148 * Changed all SilcConfigServer* and silc_config_server* to
6149 SilcServerConfig* and silc_server_config*, respectively.
6152 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6154 * Associated the ID (client or server ID) to the Authentication
6155 Payload to avoid any possibility of forging. Updated the
6156 protocol specification and the code accordingly.
6158 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6160 * The RSA key length is now save to the RsaKey context in the
6161 key generation process in lib/silccrypt/rsa.c. The key length
6162 is now used to figure out the maximum size of the block allowed
6163 to be encrypted/signed.
6165 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6166 is equivalent to the silc_mp_mp2bin but does not allocate any
6169 * Changed silc_mp_mp2bin API to take length argument. If it is
6170 non-zero then the buffer is allocated that large. If zero, then
6171 the size is approximated using silc_mp_sizeinbase, which however
6174 * Created Global RNG API which is global RNG that application can
6175 initialize. After initializing, any routine anywhere in the
6176 code (including library) can use RNG without allocating a new
6177 RNG object. This was done to allow this sort of use of the
6178 RNG in code that has no chance to allocate RNG object. All
6179 applications currently allocate this and many routines in the
6180 library use this. Affected file lib/silccrypt/silcrng.[ch].
6182 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6183 it to use the Global RNG API.
6185 * Defined Authentication Payload into protocol specification that
6186 is used during SILC session to authenticate entities. It is
6187 used for example by client to authenticate itself to the server
6188 to obtain server operator privileges.
6190 Implemented this payload into the lib/silccore/silcauth.[ch].
6191 Implemented also routines for public key based authentication
6192 as the new protocol specification dictates.
6194 Moved definitions of different authentication methods from
6195 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6197 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6198 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6199 silc_pkcs_verify_with_hash functions into the file
6200 lib/silccrypt/silcpkcs.[ch].
6202 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * The client entry's userinfo pointer must be always valid.
6205 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6206 will fail since it requires the userinfo. Now, the userinfo
6207 is allocated as "" if actual userinfo does not exist. Actually,
6208 it must exist and it is totally Ok to drop client connections
6209 that does not announce the userinfo. However, we will make
6210 this workaround for now.
6212 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6213 to return the remote port by socket.
6215 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6217 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6218 SILC_SERVER_PENDING_EXEC and added an new macro
6219 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6220 data or when error occurs while processing the pending command.
6222 Added new argument `destructor' into silc_server_command_pending
6223 and to the SilcServerCommandPending object. This destructor is
6224 now called after calling the pending callback or if error occurs
6225 immediately. If error occurs the actual pending callback won't
6226 be called at all - only the destructor. The destructor may be
6227 NULL if destructor is not needed.
6229 All this applies for client library code as well. Similar
6230 changes were made there as well for the pending commands.
6232 In the client, the application must now allocate the
6233 SilcClientCommandContext with the silc_client_command_alloc
6236 * Added reference counter to the SilcServerCommandContext. Added
6237 function silc_server_command_alloc and silc_server_command_dup
6240 Same type of functions added to the client library for the same
6243 * Removed the cmd_ident from IDListData away since it is now
6244 global for all connections. It is the command identifier used
6245 in command sending and with pending commands. The affected file
6248 * Added reference counter to the SilcSocketConnection objecet to
6249 indicate the usage count of the object. The object won't be
6250 freed untill the reference counter hits zero. Currently only
6251 server uses this, and client ignores it. The client must be
6252 set to use this too later. The affected files are
6253 lib/silccore/silcsockconn.[ch]. Added also the function
6254 silc_socket_dup to increase the reference counter.
6256 This was mainly added because it is possible that the socket
6257 is removed underneath of pending command or other async
6258 operation. Now it won't be free'd and proper DISCONNECTING
6259 flags, etc. can be set to avoid sending data to connection that
6260 is not valid anymore.
6262 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6263 the connection. After that it sets SILC_SET_DISCONNECTED.
6264 It is, however, possible that the socket data is not still freed.
6265 The silc_server_packet_process now checks that data is not
6266 read or written to connection that is DISCONNECTED. The socket
6267 get's freed when the reference counter hits zero.
6269 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6271 * Changed the client operation API: channel_message operation's
6272 `sender' is now the client entry of the sender, not the nickname
6273 and the `channel' is the channel entry, not the channel name.
6275 In the private_message operation the `sender' is now also the
6276 client entry of the sender not the nickname.
6278 Affected file is lib/silcclient/ops.h and all applications
6279 using the client operations.
6281 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6283 * Moved the calling of ops->connect() from connect_to_server_final
6284 into receive_new_id functin since that is the point when the
6285 client is actually allowed to send traffic to network. The
6286 affected file is lib/silcclient/client.c.
6288 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6291 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6292 (if needs broadcasting) instead of broadcasting the packets one
6293 by one which would make a burst in the network traffic.
6295 * Added `broadcast' argument to the functions in silcd/server.[ch]
6296 silc_server_create_new_channel[_with_id] to indicate whether
6297 to send New Channel packet to primary router.
6299 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6301 * Added new function into the silcd/server.[ch] files:
6302 silc_server_create_new_channel_with_id to create new channel with
6303 already existing Channel ID.
6305 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6306 lib/silccore/silcpacket.h. This packet is used t send list of
6307 Set Mode payloads inside one packet. Server uses this to set
6308 the modes for the channels and clients on those channels, that it
6309 announced to the router when it connected to it. The protocol
6310 specification has been updated accordingly.
6312 * The silc_server_new_channel did not handle the packet coming
6313 from normal server as it normally does not send that. However,
6314 when it announces its channels it does send it. Implemented
6315 the support for that.
6317 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6318 into the file lib/silccore/id.h.
6320 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6322 * Fixed memory leaks in the functions silc_idlist_del_client,
6323 silc_idlist_del_channel and silc_idlist_del_server in the file
6324 silcd/idlist.c. All of those leaked like a sieve.
6326 * Fixed some small memory leaks in the client's function
6327 silc_client_notify_by_server.
6329 * Added functions into silcd/server.c: silc_server_announce_clients,
6330 silc_server_announce_channels and silc_server_announce_server.
6331 These functions are used by normal and router server to announce
6332 to its primary router about clients, channels and servers (when
6333 router) that we own. This is done after we've connected to the
6336 These functions effectively implements the following packet types:
6337 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6338 and SILC_PACKET_NEW_ID_LIST.
6340 * Added new functions into the silcd/packet_receive.[ch]:
6341 silc_server_new_id_list, silc_server_new_channel_list and
6342 silc_server_new_channel_user_list to handle the incoming
6343 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6345 * Added support of changing Channel ID in the function
6346 silc_server_replace_id. If the server that announces a channel
6347 to the router already exists in the router (with same name but
6348 with different Channel ID), router is responsible to send
6349 Replace ID packet to the server and force the server to change
6350 the Channel ID to the one router has.
6352 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6353 client that the Channel ID has been changed by the router. The
6354 normal server sends this to the client. Client must start using
6355 the new Channel ID as the channel's ID.
6357 Implemented handling of this new type into lib/silcclient/client.c
6358 into the function silc_client_notify_by_server.
6360 * Added new function silc_idlist_replace_channel_id into the files
6361 silcd/idlist.[ch] to replace the Channel ID.
6363 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6365 * Call silc_server_command_identify_check always when processing
6366 the IDENTIFY command in silcd/command.c
6368 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6370 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6371 send keepalive packets. The packet can be sent by clients,
6372 servers and routers.
6374 Added function silc_socket_set_heartbeat into the file
6375 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6376 If not set, the heartbeat is not performed. The actual
6377 heartbeat is implemented in the low level socket connection
6378 library. However, application is responsible of actually
6381 Added silc_server_send_heartbeat to send the actual heartbeat
6382 packet into silcd/packet_send.[ch]. Server now performs
6383 keepalive with all connections.
6385 * Added silc_task_get_first function into lib/silcutil/silctask.c
6386 to return the timeout task with shortest timeout. There was a bug
6387 in task unregistration that caused problems. TODO has been
6388 updated to include that task system must be rewritten.
6390 * The client library will now resolve the client information when
6391 receiving JOIN notify from server for client that we know but
6392 have incomplete information.
6394 * Rewrote parts of silc_server_remove_from_channels and
6395 silc_server_remove_from_one_channel as they did not remove the
6396 channel in some circumstances even though they should've.
6398 * Encryption problem encountered in server:
6400 The LEAVE command used to send the Channel Key packet to the
6401 router immediately after generating it. However, the code
6402 had earlier sent Remove Channel user packet but not immediately,
6403 ie. it was put to queue. The order of packets in the router
6404 was that Channel Key packet was first and Remove Channel User
6405 packet was second, even though they were encrypted in the
6406 reverse order. For this reason, MAC check failed. Now, this
6407 is fixed by not sending the Channel Key packet immediately but
6408 putting it to queue. However, this is more fundamental problem:
6409 packets that are in queue should actually not be encrypted
6410 because packets that are sent immediately gets encrypted
6411 actually with wrong IV (and thus MAC check fails). So, packets
6412 that are in queue should be encrypted when they are sent to
6413 the wire and not when they put to the queue.
6415 However, the problem is that the current system has not been
6416 designed to work that way. Instead, the packet is encrypted
6417 as soon as possible and left to the queue. The queue is then
6418 just purged into wire. There won't be any fixes for this
6419 any time soon. So, the current semantic for packet sending
6422 o If you send packet to remote host and do not force the send
6423 (the packet will be in queue) then all subsequent packets to the
6424 same remote host must also be put to the queue. Only after the
6425 queue has been purged is it safe again to force the packet
6428 o If you send all packets immediately then it safe to send
6429 any of subsequent packets through the queue, however, after
6430 the first packet is put to queue then any subsequent packets
6431 must also be put to the queue.
6433 Follow these rules and everything works fine.
6435 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6437 * Added new function silc_server_remove_clients_by_server to
6438 remove all client entries from ID list when the server connection
6439 is lost. In this case it is also important to invalidate all
6440 client entires as they hold the invalid server entry. This
6441 fixes fatal bug when server has lost connection and will reconnect
6444 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Made some sanity checks to silc_server_daemonise like to check
6447 whether the requested user and group actually exists.
6449 * Added sanity check to SKE's silc_ske_responder_finish to check
6450 that the public and private key actually is valid.
6452 * Invalidate the client's nickname when receiving Replace ID
6453 packet and the Client ID is being replaced. This means that the
6454 server will query the nickname if someone needs it (client)
6457 * Sort the ID Cache in client library when the ID Cache data
6458 has changed (needs sorting).
6460 * Do not allow for SILC client to create several connections to
6461 several servers. The client does not support windows right now
6462 and generating multiple connections causes weird behaviour.
6464 Irssi-silc client does support windows and can handle several
6465 connections without problems, see: www.irssi.org and SILC plugin.
6467 * Fixed some places where client was added to the IDList. The
6468 rule of thumb is following (in order to get everything right):
6469 If the client is directly connected local client then the
6470 `connection' argument must be set and `router' argument must be
6471 NULL to silc_idlist_add_client function. If the client is not
6472 directly connected client then the `router' argument must
6473 bet set and the `connection' argument must be NULL to the
6474 silc_idlist_add_client function.
6476 * The funtion silc_server_packet_send_local_channel actually did
6477 not check whether the client was locally connected or not. It
6478 does that now. Fixed a bug related to LEAVE command.
6480 * Fixed Remove Channel User payload parsing bug in server's
6481 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6483 * The server's silc_server_save_channel_key now checks also the
6484 global ID list for the channel as it might not be in the local
6485 list. Fixed a bug related to LEAVE command.
6487 * Is this the end of the [<unknown>] buglet that has been lurking
6488 around for a long time? A little for loop fix in server's
6489 silc_server_command_whois_parse that is used by both IDENTIFY
6490 and WHOIS command. At least, this was a clear bug and a cause
6491 of one type of [<unknown>] buglet.
6493 * WHOIS and IDENTIFY commands call the function
6494 silc_server_command_[whois/identify]_check function even if
6495 we are not router server.
6497 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6499 * Added --with-gmp configuration option. If set the GMP
6500 is always compiled in the SILC source tree. If not set then
6501 it is checked whether the system has the GMP3 installed. If
6502 it has then the GMP won't be compiled (the system's headers
6503 and library is used), if it doesn't have it then the GMP is
6504 compiled in the SILC source tree.
6506 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6508 * Changed RSA private exponent generation to what PKCS #1
6509 suggests. We try to find the smallest possible d by doing
6510 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6511 not security fix but optimization.
6513 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6515 * Added new config entry [Identity] to fork the server and run
6516 it as specific user and group. A patch from Bostik.
6518 * Imported Dotconf configuration library into lib/dotconf.
6519 This will be used to create the SILC configuration files later.
6520 It will appear in the distsribution after this commit.
6522 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6524 * A big code auditing weekend happening. Auditing code for
6525 obvious mistakes, bugs and errors. Also, removing any code
6528 Removed files for being obsolete:
6530 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6531 inline in the file lib/silcutil/silcbuffer.h)
6533 o lib/silcutil/silcbufutil.c (the header has inline versions)
6535 Changed code to fix possible error conditions:
6537 o The buffer formatting routines now check that the destination
6538 buffer really has enough space to add the data. This applies for
6539 both buffer formatting and unformatting
6540 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6541 unformatting was changed to accomodate following rules:
6542 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6543 sent to the function while XXX_*STRING will not allocate or copy
6544 the data into the buffer. Instead it sets the pointer from the
6545 buffer into the pointer sent as argument (XXX_*STRING used to
6546 require that the pointer must be allocated already). This change
6547 makes this whole thing a bit more consistent and more optimized
6548 (note that the data returned in the unformatting with XXX_*STRING
6549 must not be freed now). The routines return now -1 on error.
6551 o Tried to find all code that use buffer_format and buffer_unformat
6552 and added return value checking to prevent formatting and
6553 especially unformatting errors and possible subsequent fatal
6556 o Changed ske->x and ske->KEY to mallocated pointers in
6557 lib/silcske/silcske.h. Fixed possible data and memory leak.
6559 o Added return value checking to all *_parse* functions. Fixed
6560 many memory leaks as well.
6562 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6563 so that buffer overflows would not happen. All code now also
6564 checks the return value as it can fail.
6566 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * Added reconnection support to server if the normal server looses
6569 its connection to the router (for example if router is rebooted).
6570 The server performs normal reconnection strategy implemented
6571 to the server. Affected file silcd/server.c.
6573 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6575 * Added new packet type SILC_PACKET_SET_MODE that is used to
6576 distribute the information about changed modes (for clients,
6577 channels and clients channel modes) to all routers in the
6578 network. Updated the protocol specification accordingly.
6580 Added functions into silcd/packet_send.c and
6581 silcd/packet_receive.c: silc_server_send_set_mode,
6582 silc_server_set_mode.
6584 Added new files silcmode.[ch] into lib/silccore that implements
6585 the encoding and decoding of Set Mode Payload. Added new type
6586 SilcSetModePayload. Moved the definitions of different modes
6587 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6589 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6591 * Oops, a little mistake in server's connection authentication
6592 protocol. The protocol is not ended with FAILURE but with
6593 SUCCESS if the authentication is Ok. :) Affected file is
6596 * Implemented NICK_CHANGE notify handling in server in the file
6597 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6598 the local clients on the channel. After the changing nickname
6599 in router environment snhould work and the [<unknown>] nickname
6600 should appear no more.
6602 The silc_server_replace_id function that receives the Replace ID
6603 payload now sends the NICK_CHANGE notify type also in the file
6604 silcd/packet_receive.c
6606 * Changed WHOIS and IDENTIFY command to support the maximum amount
6607 of arguments defined in protocol specs (3328 arguments). This
6608 fixed a bug that caused problems when there were more than three
6611 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6613 * Added extra parameter, command identifier, to the
6614 silc_client_send_command so that explicit command identifier
6617 Changed that ID list routines uses specific command identifier
6618 when sending WHOIS/IDENTIFY requests to the server so that they
6619 can be identified when the reply comes back.
6621 Affected files lib/silcclient/command.[ch],
6622 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6624 * Added `sender' argument to silc_server_packet_send_to_channel
6625 to indicaet the sender who originally sent the packet to us
6626 that we are now re-sending. Ignored if NULL. Affected file
6627 silcd/packet_send.[ch].
6629 * Added some server statistics support in silcd/server_internal.h
6630 SilcServerStatistics structure and around the server code. Also
6631 send some nice statistics information when client is connecting
6634 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6636 * Fixed channel ID decoding in server's JOIN command reply in
6637 silcd/command_reply.c
6639 * Fixed braodcasting of replace ID payload to not to send it if
6640 we are standalone server in silcd/packet_receive.c.
6642 * Fixed all channel message sending routines to not to send
6643 packets to clients that has router set, since they are routed
6644 separately in the same function earlier. Affects file
6645 silcd/packet_send.c and all channel packet sending functions.
6647 * In USERS reply, res_argv[i] are not allocated, the table
6648 is allocated. Thus changed that free the table, not its
6651 * In server's whois_check and identify_check if the client is
6652 locally connected do not send any WHOIS commands - they are not
6655 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6657 * Fixed some minor bugs in client when sending WHOIS command. The
6658 arguments was in wrong order.
6660 * Removed statis function add_to_channel from server in
6661 silcd/command.c that was previously used with the joining but
6664 * Tested USERS command in router environment successfully with two
6665 routers, two servers and two clients.
6667 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6669 * Reorganized the USERS command and command reply in client library
6670 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6671 When the command is given by user we register a pending command
6672 callback that will reprocess the command after the reply has been
6673 received from the server. When reprocessing the packet we then
6674 display the information. Thus, the USERS information is displayed
6675 now in the command callback instead of in the command reply
6676 callback. The processing of the command is same as previously
6677 when server has sent the command reply in the JOINing process.
6679 * Added to USERS command in silcd/command_reply.c to join the client,
6680 we didn't use to know about, to the channel after we've created
6681 a client entry for it. Also, for clienet we did know already still
6682 check whether it is on the channel or not and add it if not.
6684 * Removed silc_server_command_join_notify as the function and its
6687 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6689 * Changed the client's pending command handling to the same as the
6690 server's pending command handling. It is also now possible to
6691 execute command reply functions from other command reply
6692 function as the function callbacks for commands and command
6693 replies are one and same. The pending commands are not static
6694 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6695 in client connection context. Thus, pending commands are server
6696 connection specific as it is convenient.
6698 Changed the function silc_client_command_pending and
6699 silc_client_command_pending_del and added new function
6700 silc_client_command_pending_check. Removed the
6701 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6704 * Added cmd_ident, current command identifier, to the client
6705 connection context in lib/silcclient/client.h to keep track on
6706 command identifiers used in command sending. Client's command reply
6707 function handling now supports the mandatory command identifiers.
6709 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6710 funtions in client to fully support pending command callbacks.
6712 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6713 as one of the arguments to the application in the command reply
6716 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6717 before first releasing SILC but came back. Now it is removed again
6718 and should come back nomore. The FORWARDED flag was used only
6719 by the JOINing procedure by forwarding the command packet to router.
6720 Now, the JOINing procedure has been changed to more generic (due
6721 to various router environment issues) and FORWARDED is not needed
6722 anymore for anything. The protocol specification is yet to be
6725 Now, removed silc_server_packet_forward from server and the flag
6726 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6728 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6730 * Renamed NAMES command to USERS command. The NAMES was named that
6731 due to historical reasons. Now it is renamed. Also, rewrote
6732 parts of the USERS command. The nickname list is not sent anymore
6733 by the server. Only Client ID and mode lists are sent in the USERS
6734 command. Changed this also to the protocol specification.
6736 The client now resolves the names and stuff after it receives
6737 the USERS list from the server when joining to the channel.
6739 * WHOIS and IDENTIFY commands has been changed to support multiple
6740 Client ID's per command. One can now search for multiple users
6741 in the network by sending only one WHOIS or IDENTIFY command.
6742 Changed the code and the protocol specifications.
6744 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6745 uses silc_server_command_whois_parse to parse the request. */
6747 * If normal server, do not parse the WHOIS and IDENTIFY requests
6748 before sending it to the router. Saves some time.
6750 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6752 * Fixed JOIN command on client library. Wrong number of arguments
6753 used to crash the client.
6755 * Added silc_server_channel_has_global function to check whether
6756 channel has global users or not.
6758 * Added silc_server_channel_has_local function to check whether channel
6759 has locally connected clients on the channel.
6761 * The silc_server_remove_from_one_channel now checks whether the
6762 channel has global users or not after given client was removed from
6763 the channel. It also checks whether the channel has local clients
6764 on the channel anymore. If it does not have then the channel entry
6765 is removed as it is not needed anymore.
6767 * The silc_server_notify now checks on JOIN notify whether the joining
6768 client is one of locally connected or global. If it is global then
6769 the channel has now global users on the channel and that is marked
6770 to the channel entry. Also, it now saves the global client to
6771 global list who is joining and JOINs it to the channel. This is
6772 for normal server, that is.
6774 Changed silc_server_send_notify_on_channel,
6775 silc_server_packet_relay_to_channel and
6776 silc_server_packet_send_to_channel check if we are normal server
6777 and client has router set (ie. global client) do not send the
6778 message to that client, as it is already routed to our router.
6780 * Implemented LEAVE notify type handling in silc_server_notify
6783 * Tested LEAVE command in router environment successfully. Tested
6784 with two routers, two servers and two clients.
6788 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6790 * Implemented SIGNOFF notify type handling in silc_server_notify
6793 * silc_server_remove_id now removes the client entry from all channels
6794 it has joined and thusly sends SIGNOFF notify type.
6796 * Rewrote the NAMES list generation in server by removing two excess
6797 loops. The lists are created now inside one loop.
6799 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6801 * silc_server_remove_channel_user checks now also global list
6802 for channel and client.
6804 * silc_server_new_channel_user checks now both local and global
6805 list for channel and client. Fixed a bug in client id decoding.
6806 Used to decode wrong buffer.
6808 * silc_server_channel_message checks now both local and global
6809 list for channel entry.
6811 * Tested channel joining (hence JOIN) in router environment
6812 successfully. Tested with two routers, two servers and two
6815 * Tested channel message sending in router environment successfully.
6817 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Added silc_server_save_channel_key into server.[ch] to save the
6820 received channel key in Channel Key payload processing. It is
6821 also used in JOIN command reply handling.
6823 Equivalent function silc_client_save_channel_key added into
6824 client.[ch] into client library.
6826 * Changed JOIN command reply to send information whether the channel
6827 was created or not (is existing already) and the channel key
6828 payload. Changed protocol specs accordingly.
6830 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6831 the request was sent by ID and not by nickname. Crashed on
6834 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6837 now correctly save the received data.
6839 * silc_server_free_sock_user_data now notifies routers in the
6840 network about entities leaving the network.
6842 At the same time implemented functions silc_server_remove_id
6843 and silc_server_send_remove_id to receive and send REMOVE_ID
6844 packets. The packet is used to notify routers in the network
6845 about leaving entities. The ID removed will become invalid in
6848 * Added function silc_idlist_del_server into server. Removes and
6849 free's server entry from ID list.
6851 * silc_server_private_message function now checks, if we are router,
6852 that the destination ID really is valid ID, naturally.
6854 * In router when NEW_ID packet is received (for new client) the
6855 hash of the Client ID is saved in the ID Cache but the
6856 client->nickname is set to NULL, instead of putting the hash
6859 IDENTIFY command now also checks that client->nickname must be
6860 valid. If it is not if will request the data from the server who
6861 owns the client. Added new function
6862 silc_server_command_identify_check.
6864 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6865 to set the command to already allocated Command Payload.
6867 * Tested private message sending in router environment with two
6868 routers, two servers and two clients. Fixed minor bugs and now
6871 * Fixed segfault from client's NAMES command. Used to crash if
6874 * Forwarded packets must not be routed even if it is not destined
6875 to the receiver. Changed server code comply with this.
6877 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Added `require_reverse_mapping' boolean value to ServerParams
6880 structure. If TRUE (not default) the server will require that
6881 the connecting host has fully qualified domain name.
6883 If the reverse mapping is not required and hostname could not be
6884 found the IP address is used as hostname.
6886 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6888 * Implemented version string checking to both client and server.
6889 The check is incomplete currently due to the abnormal version
6890 strings used in development version of SILC.
6892 * Changed all command functions in server to use the new
6895 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Changed char *data to unsigned char *data in ID Cache system to
6898 support binary data as ID Cache data. Changed code to support
6899 binary data in lib/silccore/idcache.c.
6901 * Renamed silc_server_packet_relay_command_reply to
6902 silc_server_command_reply as it is normal packet receiving
6903 function. Rewrote the function to accept command replys for
6904 servers and not only for clients.
6906 * Mark remote router always as registered server if we are connecting
6907 to it. Otherwise, commands sent by the router to us are ignored.
6909 * All ID List find routines now returns the ID Cache Entry pointer
6910 as well if requested.
6912 * WHOIS command works now in router environment, tested with two
6913 routers, two servers and two clients.
6915 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6916 in router environment (as it is almost equivalent to WHOIS) but
6917 hasn't been tested thoroughly. Added new functions:
6919 silc_server_command_identify_parse
6920 silc_server_command_identify_send_reply
6921 silc_server_command_identify_from_client
6922 silc_server_command_identify_from_server
6924 * Disabled route cache adding because adding two different ID's with
6925 same IP replaces the old cache entry thus giving wrong route.
6926 The entry->router->connection is always the fastest route anyway
6927 so route cache may not be needed. Of course, new routes maybe
6928 established after receiving the ID when the entry->router->connection
6929 might not be anymore the most optimal.
6931 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * Add route cache for received ID for fast routing.
6935 * Added silc_server_packet_route to route received packet on router
6936 that is not destined to us.
6938 * Renamed silc_server_get_route to silc_server_route_get.
6940 * Added id_string and id_string_len fields into SilcServer to
6941 include encoded ServerID for fast comparing without excess
6942 encoding of the ID's.
6944 * Cleaned up WHOIS command on server side. Added following static
6947 silc_server_command_whois_parse
6948 silc_server_command_whois_check
6949 silc_server_command_whois_send_reply
6950 silc_server_command_whois_from_client
6951 silc_server_command_whois_from_server
6953 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6954 arguments in command replies. All command functions should be
6955 updated to use this macro.
6957 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6959 * Minor typo fixes on command reply handling on server.
6961 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6963 * Added silc_server_command_add_to_channel internal routine to add
6964 the client to the channel after router has created the channel and
6965 sent command reply to the server.
6967 * Added generic silc_server_send_command to send any command from
6970 * Use static buffer with ID rendering instead of duplicating data.
6972 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6974 * Fixed a channel user mode bug when joining to a channel server gave
6975 everybody channel founder rights, oops.
6977 * We mark ourselves as the router of the incoming server connection
6978 if we are router ourselves. This way we can check in some packet
6979 sending functions whether it is locally connected server. For
6980 incoming router connections we put NULL.
6982 * For router sending packets locally means now always sending the
6983 packet cell wide; to local clients and local servers. For normal
6984 server sending packet locally means sending it to only local
6987 * Fixed the JOIN command to really work in router environment. If the
6988 channel is created it is always created by the router. Router is
6989 also responsible of making the initial joining to the channel,
6990 sending JOIN notify to the sending server and distributing
6991 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6992 does not exist server doesn't do anything else but forward the
6993 command to the router which performs everything.
6995 * Added silc_server_send_channel_key function to send the Channel Key
6998 * Added silc_server_create_channel_key to create new channel key. The
6999 channel key is now re-generated everytime someone joins or leaves
7000 a channel, as protocol dictates. Note: channel->key_len is the
7003 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7005 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7006 packet_receive.[ch] to separate packet sending and receiving
7007 routines. The server.[ch] now includes everything else including
7008 actual packet processing (writing and reading data) and other
7011 Renamed silc_server_private_message_send_internal to
7012 silc_server_send_private_message. The routine is still though
7013 used only to relay private messages as server does not send
7014 private messages itself.
7016 Renamed silc_server_new_channel to silc_server_create_new_channel
7017 and added new function sicl_server_new_channel that handles the
7018 incoming New Channel packet. Added also new sending function
7019 silc_server_send_new_channel to send New Channel Payload.
7021 * Added new function silc_server_notify to process incoming notify
7022 packet to the server/router. Server may then relay the notify
7023 to clients if needed.
7025 * Added new function silc_server_new_channel_user to process incoming
7026 New Channel User packet. Router will redistribute the packet and
7027 send JOIN notify to its local clients and locally connected servers
7028 if needed. Normal server will send JOIN notify to its local client
7029 on same channel when received this packet. Added also corresponding
7030 sending function silc_server_send_new_channel_user to sent the
7033 * Added boolean route argument to send_notif_to_channel and
7034 packet_send_to_channel functions to attempt to route the packet
7035 if it is TRUE and send only locally if it is FALSE.
7037 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7039 * silc_server_replace_id now broadcasts the received replace ID
7040 packet if it is not broadcast packet already. The router must
7041 broadcast to inform other routers about changed ID.
7043 * Added backpointer to server's router into SilcServer context in
7044 silcd/server_internal.h.
7046 * Fixed silc_server_packet_broadcast to send correct broadcast
7049 * The channel key is now distributed to the local client as soon
7050 as it is received from the router (in router environment) so that
7051 no other packet may be sent for the channel until client has
7054 * silc_server_remove_channel_user now broadcasts the received
7055 Remove Channel User packet if it is not broadcast packet already.
7056 The router must broadcast to inform other routers about removed
7059 * Added users field into SilcPacketContext that is a reference count
7060 of the context. One can increase the reference count by calling
7061 silc_packet_context_dup which is now changed to just increase the
7062 reference count instead of duplicating the data. The reference
7063 count is decresed by calling silc_packet_context_free that will
7064 free the data after the reference count hits zero.
7066 For now on the packet context and everything allocated into it
7067 (including the raw packet from network) must be freed by calling
7068 the new silc_packet_context_free function. Added also new function
7069 silc_packet_context_alloc that must be used now to allocate the
7070 context. This also means that if a routine is asynchronous from
7071 silc_[client/server]_packet_parse_type the packet context must
7072 be duplicated by calling silc_packet_context_dup. Otherwise it
7073 gets free'd after silc_[client/server]_packet_parse_type returns.
7074 Also, one must remember that if packet is duplicated then its
7075 reference count must be decresed by calling the free function as
7076 many times as it was duplicated.
7078 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7079 from both client and server.
7081 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7083 * Made joining to a channel working in router environment.
7085 * Cleaned up JOIN command on server side and create function
7086 silc_server_command_join_channel internal routine to make the
7089 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7091 * Changed silc_command_pending list to SilcDList. Also, added
7092 `ident' field to SilcServerCommandPending structure to identify
7093 the reply and to call correct callback.
7095 Added silc_server_command_pending_check function to replace the
7096 corresnponding macro. The silc_command_pending list is not
7099 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7100 to set identifier to previously allocated Command Payload. It
7101 is used to set identifier for command when resending Command
7104 * Added silc_command_payload_encode_payload to encode Command
7105 Payload buffer from SilcCommandPayload structure.
7107 * Added silc_argument_payload_encode_payload to encode Argument
7108 payload buffer from SilcArgumentPayload structure.
7110 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7112 * Changed WHOIS command to support router connection on server side.
7113 The whois request is always sent to router unless the server is
7114 standalone server. After server has received the reply from the
7115 router will it send the reply to the client.
7117 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7118 broadcast received broadcast packet. The function is used only
7119 by router. The broadcast packet is always sent to the router's
7122 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7123 render given ID to printable string, for log files for example.
7125 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7127 * Made basic router to router connections working. At least they
7128 can now connect to each other but nothing really works the way
7129 they are supposed - yet.
7131 * Added new initiator token to RouterConnection configuration
7132 file in silcd/serverconfig.[ch]. It is used to tell whether we
7133 are the initiator to the remote router or whether we'll expect
7134 the other end to connect.
7136 * Moved registering of listener task to silc_server_init, hence
7137 the server starts listenning as soon as it is run, even if it
7138 does not have connections to other routers. Let's see how well
7141 * Changed default connection retry timeouts for more suitable in
7144 * Removed cipher and such arguments from silc_idlist_add_client
7145 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7146 Added new function silc_idlist_add_data to add the keys and stuff
7149 * Added SilcIDListData structure and added it to SilcClientEntry
7150 and SilcServerEntry as their first field in the structure. This
7151 way we can explicitly cast the ID entries to the SilcIDListData
7152 structure and get common data for the entries. In past, we had
7153 to first check what type of connection it is and then cast it to
7154 correct ID entry type. Now, we can directly cast the opaque
7155 pointer to the SilcIDListData (no matter what ID entry it actually
7156 is) and get the data needed.
7158 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7160 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7161 in some circumstances even if threre were timeout tasks, though not
7162 IO tasks, but tasks anyway. Now fixed.
7164 * Defined SilcServerConnection structure to hold connection specific
7165 stuff about directly connected servers and routers. The definition
7166 is currently in silcd/server_internal.h. I thought about having
7167 a bit more important role fro this struct but for now it is used
7168 only when connecting to other server (or router actually).
7170 * Added connecting retry support in server when connecting to
7171 router(s). The retry feature implement exponential backoff
7172 algorithm. Also, added SilcServerParams structure to hold default
7173 parameters for server. For now, it include these retry settings
7174 and are hard coded. After server is moded to be as Silc Server
7175 Library this structure will be more important.
7177 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7179 * Changed client librarys channel->clients table to SilcList and
7180 changed code accordingly.
7182 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7184 * Changed client's channel table to SilcList and changed code
7185 accordingly. Also changed SilcChannelClientEntry to include back-
7186 pointer to the channel so that client entry can use that structure
7187 as list as well and we have fast cross-reference to the channel.
7188 This change dramatically decreased the complexity of channel
7189 handling with client entry and vice versa (removed one extra
7190 loop when searching for channel entry from many functions).
7192 * Changed server->sim from table to SilcDList and changed code
7195 * NAMES command can now be used from user interface. It will show
7196 the user list on the channel, neatly.
7198 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7199 Code now saves realname of the user if it becomes available.
7201 * Renamed configure.in to configure.in.pre and made ./prepare
7202 script to automatically add correct version string to
7203 configure.in which it creates from configure.in.pre.
7205 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7207 * NAMES command reply now shows users mode with the nickname when
7210 * Moved silc_client_ch[u]mode[_char] functions from
7211 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7212 place sucks, they are utility functions and should be in some
7215 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7217 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7220 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7224 * Added TRQ (efficient deque and list library) into lib/trq. This is
7225 a very good list library that is currently used in the SILC. Defined
7226 SilcList API over the library because I didn't like the API very
7227 much. See lib/trq/silclist.h for the API and examples of how to
7228 use the API. Fixed various places in the code to use the new
7229 SilcList API. The SilcList is meant for lists that has a structure
7230 already defined as a list. It is not suitable to add just some
7231 context to the list (in TRQ, the context is the list actually).
7233 So, I defined SilcDList that can be used for the purpose where
7234 predefined list structure does not exit. This can be used as
7235 such list. Now some context just can be added to the SilcDList.
7236 Currently this list is not used in the SILC just yet, though there
7237 are a lot places where this can replace dynamically allocated
7238 tables and I will fix these places, later, to use SilcDList.
7239 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7240 and use TRQ internally).
7242 Also fixed some annoying warning messages that the original TRQ
7243 code generated. Also minor changes to TRQ's Makefile.in.
7245 * Added support for querying by Client ID to both WHOIS and
7246 IDENTIFY commands into server, as required by the protocol.
7248 * Removed method function pointers from SilcBuffer structure. They
7249 weren't used to anything and just increased the context size for
7250 no good reason. This change also made silc_buffer_alloc and
7251 silc_buffer_free functions inline functions.
7253 * Disabled command flooding detection support until it's fixed so
7254 that it accepts commands in but does not execute them more than once
7257 * Added silc_net_localhost(), to return local hostname, into
7258 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7259 that must be initialized before calling silc_client_init.
7261 * Added new function: silc_server_send_notify_on_channels to send
7262 notify messages to all channels client has joined. It is assured
7263 that the message is sent only once per client.
7265 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7266 lib/silcutil/silcutil.[ch] as silc_format function. The new
7267 function is generic and is used by server as well, not only by
7268 the logging routines.
7270 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7271 the provided version string was not acceptable. Added new function:
7272 silc_ske_check_version into lib/silcske/silcske.h. The function
7273 must be implemented by the application (client or server) and it
7274 does not reside in the SKE library. The function checks the version
7275 string remote end sent.
7277 * Added back pointers (to opaque context and to SilcSocketConnection)
7278 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7280 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7281 duplicate packet context structure.
7283 * Changed `notify' client operation to send same arguments as client
7284 receives from server except for ID's. ID's are mapped to correct
7285 ID entry and that is returned. Also, if channel entry is not sent
7286 by server but the notify is for channel the channel entry is sent
7287 to application (otherwise application doesn't know that it is for
7288 channel (library gets it from packet's Destination ID)).
7290 * Added silc_client_remove_from_channels into client library to
7291 remove a client from all channels it has joined to. Used when
7292 received SIGNOFF notify from server. Added also new function
7293 silc_client_replace_from_channels to replace old ID entry with
7294 new ID entry on all channels. Used when received NICK_CHANGE
7297 * Fixed ID Cache list handling in silc_idlist_get_client in
7298 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7299 to get (or query) client by ID.
7301 * Updated TODO list.
7303 * Added connection authentication status message defined by the
7304 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7305 support for these into the code in client and server side.
7307 * Added generic function silc_client_send_command to send any command
7308 with variable argument list. Application should use this function
7309 to send commands if the command functions provided by the library
7310 does not suite for the application's user interface needs.
7312 * Added new `failure' client operation. Application is notified about
7313 received failure packet if client is executing a protocol. In this
7314 case the protocol's execution has failed.
7316 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7317 is required by the protocol.
7319 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7320 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7323 * Added status flag to SilcSKE object to indicate realtime status
7324 of the SKE protocol.
7326 * Application receives now exactly same command reply arguments as
7327 the library receives from server. However, if ID is received the
7328 corresponding ID entry is returned to the application (eg. Client
7329 ID is mapped to correct SilcClientEntry entry and that is returned).
7330 Changed command_reply client operation due to this change.
7332 * Changed all ID's in commands and in command replys as ID Payloads.
7333 Change affected both client and server side codes.
7335 All ID's sent in SILC network (with execption of ID's in SILC
7336 Packet header) are sent in ID Payload to support variable length
7339 * Server now notifies nick changes and notifies all clients on
7340 the channels about the new nickname (about the new Client ID,
7343 * Implemented CMODE command to change channel modes. Supports all
7344 channel modes defined by the protocol specs except ban and invite
7345 lists. (Also, private channel key mode is supported but support for
7346 setting private channel key in client is missing, thus, this mode
7347 has no effect on client side (except that server requires that the
7348 client uses private channel key and normal channel traffic does not
7351 Also, invite mode works per se, but INVITE command does not work
7352 yet correctly, so you can set channel as invite only channel but
7353 inviting clients to the channel does not work (it is yet to be
7354 thought what's the best way to do it).
7356 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7357 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7358 Implemented CUMODE command to change user's mode on the channel.
7359 Supports all modes defined by the protocol specs.
7361 * Added NAMES command reply to return users modes on the channel.
7363 * Removed unnecessary and slow ciphers from lib/silccrypt.
7365 * Set SO_KEEPALIVE option to connection sockets by default.
7367 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7369 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7370 redefined the Notify Payload into protocol specs.
7372 * Added silc_id_payload_parse_id to get ID directly from raw
7375 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7377 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7378 accept searching by Client ID as well.
7380 * Added support for LEAVE and SIGNOFF notify types in client library.
7382 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7383 to parse ID Payload from raw data.
7385 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7387 * Added flags parameter into silc_ske_assemble_security_properties
7388 function in lib/silcske/silcske.[ch].
7390 * Changed notify client operation to fit better for notify messages
7391 sent by server. The notify payload received from server is now
7392 passed to the application (after parsing it to SilcNotifyPayload).
7393 It is application's responsibility to retrieve the arguments
7394 from the payload and show the message the way it wants. The message
7395 sent by server is implementation specific.
7397 * Changed public keys to comply with the protocol specification.
7398 Old public keys are not supported anymore and are not compatible.
7400 * Removed nickname from Channel Payload as the latest draft removed
7401 it. The client must resolve the nickname from the NAMES command
7402 reply received when it joined the channel.
7404 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7406 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7408 * Fixed some errors in protocol specification drafts.
7410 * Created lib/silccore/silcnotify.c to implement Notify Payload
7411 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7412 generic payloads described by protocol specifications. The file
7413 includes implementations for ID Payload and Argument Payload.
7415 * Changed Command Payload implementation to use the new Argument
7416 Payload. Changed command_xxxx_payload to command_payload_xxxx
7417 to comply with SILC coding conventions.
7419 * Added suppport for Argument Payload handling in Notify Payload
7420 implementation as protocol requires it. Added the new support
7421 into server and client lib as well.
7423 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7425 * Added support for multiple nicknames on same channel. [n] is
7426 added locally to the nickname if there are more than one same
7427 nicknames on the channel.
7429 * Server now sends all nicknames that matched WHOIS request.
7430 Client also shows the list received from server.
7432 * Added TOPIC command to client side. User can now set and show
7433 current topic on channel.
7435 * Added MOTD command to client and server. Also, server sends the
7436 motd when client connects to the server.
7438 * Changed version strings to comply ISO 8601.
7440 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7442 * Fixed protocol error handling in client library. It should now
7443 cope even if the SKE fails for some reason.
7445 * Made new protocol specification drafts for submitting to IETF.
7447 * Implemented TOPIC command to server in silcd/command.c.
7449 * Added two new notify types into lib/silccore/silcnotify.h:
7450 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7451 notify nickname change and topic setting/change on a channel.
7453 * API change of command_reply operation in client library. The
7454 application gets now the status type received from server as well.
7456 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7458 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7460 * Cras fixed and optimized the packet handling even further and
7461 it should work now. Minor change to the prototype of function
7462 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7464 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7466 * Added new function into lib/silcutil/silcschedule.[ch]:
7467 silc_schedule_with_fd to select() a specified fd. The function
7468 returns after timeout expires or data arrives or goes. The
7469 function is used by packet routines to wait that all data is
7470 received from network.
7472 * Fixed data reading from network in lib/silccore/silcpacket.c.
7473 The code now assures that all data is read from the fd and then
7474 continues packet processing. This was a bug fix since the code
7475 used to drop some data in some circumstances.
7477 * Added new function into lib/silcclient/client.[ch]:
7478 silc_client_start_key_exchange to start key exchange after
7479 connection has been established to server. The code internally
7480 now uses this funtion but its main purpose was to provide it
7481 for applications that perform their own connecting. After
7482 application has created a connection it merely calls this
7483 function to start the key exchange between client and server.
7484 The library takes care of everything else after that.
7486 Updated also lib/silcclient/README to explain the usage of
7489 * Do not send to application information that connection has
7490 been established. Application gets notified it by connect
7493 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Applied cras's patch to add silc_schedule_one function. The
7496 function runs scheduler once and returns.
7498 * Fixed the scheduler after cras messed it up. The timeout
7499 handling works now as it's supposed to work.
7501 * Added into lib/silccore/ silcnotify.h to include notify
7502 message types support. Changed silc_server_send_notify*
7503 functions, in server.[ch], to support those new notify types.
7504 Added the support for the notify types into client library,
7505 as well. Added new notify client operation into ops.h in
7508 * Changed silc_server_packet_send_to_channel to send normal
7509 packets instead of just channel message packets. The function
7510 is now used to send the notify packets to channels. It is not
7511 used to send channel message packets anymore, as server never
7514 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7515 va_arg()s as it seems to require it nowadays. I guess, if SILC
7516 is compiled with older va_arg() the new code should work anyway.
7518 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7520 * Splitted core library. Core library (lib/silccore) includes
7521 now only SILC protocol specific core (and common) components.
7522 Created new utility library (lib/silcutil) that includes more
7523 generic purpose stuff. The stuff for util library was taken
7524 from the old core library. This was minor and easy split.
7526 * Created SILC Client Library (lib/silcclient) that includes
7527 implementation of the SILC client without user interface. This
7528 was major move from silc/ directory. The code has been changed
7529 so that it is transparent towards the user interface. The
7530 silc/ directory includes now the same user interface as before
7531 and it uses the new client library. Read lib/silcclient/README.
7532 Basicly, the client library performs everything else related
7533 to SILC except user interface handling. Also, configuration
7534 files are considered to be part of user interface and library
7535 does not handle them.
7537 This change also changed a lot of structures, function naming etc.
7538 Most important change was that SilcClientWindow object was
7539 renamed to SilcClientConnection in the client library. Created
7540 also new file lib/silcclient/ops.h. Also added new files
7541 silc/local_command.[ch] and silc/client_ops.[ch].
7543 All these changes were made to make it easier for user interface
7544 designers to create what ever user interface for the SILC client
7547 It is also expected that the server will be moved to lib
7548 directory as well and SILC Server Library will be created;
7549 sometimes in the future.
7551 * Removed Local commands from lib/silccore/silccommand.h as
7552 they are application specific and new client library does not
7553 handle any of those anymore.
7555 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7556 old client implementation in silc/.
7558 * Added support for callback functions in SILC_LOG_* macros.
7559 Application can now set its own callbacks that will be called
7560 instead of using the default functions that will always print
7561 the debug messages to stderr (or stdout). Also, debugging can
7562 now be disabled by setting silc_debug to FALSE and re-enabled by
7563 setting it to TRUE. Note, that logging will still work even
7564 if debugging is disabled.
7566 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7567 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7568 silc_log_reset_debug_callbacks.
7570 * To enable debugging in silc client one must give now -d
7571 option on command line.
7573 * Changed silc_schedule_init to automatically allocate task queues
7574 if they are not allocated before calling it.
7576 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7578 * Added GMP 3.1 into math library.
7580 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7582 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7583 a channel in SILC network. The packet is used by servers and
7584 routers to notify other routers that user has left a channel.
7585 This little feature was missing until now. Added the feature
7586 to protocol specification as well.
7588 Added functions: silc_server_send_remove_channel_user and
7589 silc_server_remove_channel_user into server.[ch].
7591 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7592 lib/silccore/silcpacket.h. However, they are not implemented
7595 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7597 * Fixed joining to a channel and sending channel messages
7598 between server and router. The channel message sending should
7599 now work inside a cell.
7601 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7603 * Fixed the private message sending between server and router.
7604 The private message sending should now work inside a cell.
7606 * Added silc_server_replace_id into server.[ch] to replace
7607 existing ID in the SILC network.
7609 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7610 and silc_idlist_replace_server_id into idlist.[ch] in server.
7612 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7614 * Fixed the server to server connections. Server can again now
7615 connect to router. Router to router connections probably does
7618 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7620 * Added dynamic protocol registering support. Now protocols can
7621 registered and unregistered on the fly. Patch by cras.
7623 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7625 * Added lib/contrib directory to hold routines that some platforms
7626 don't have but are needed by SILC.
7628 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7629 into lin/contrib to provide getopt() and getopt_long() for
7630 those who don't have it.
7632 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7634 * Added AWAY command to client. When away message is set and
7635 client receives a private message packet the client automatically
7636 replies to the sender with the away message.
7638 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7639 bug seemed to be the cause of recent problems when compiling
7642 * Added version detection support to SKE protocol specification
7643 and added the new changes to the SKE implementation as well.
7644 There were other minor changes in the SKE protocol as well.
7646 Many changes in lib/silcske/silcske.[ch] and in
7647 lib/silcske/payload.[ch].
7649 * Added ^U functionality, clear input line. Patch from cras.
7651 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7653 * Mainly small bugfixes on core library. Fixed some debugging
7654 logging and buffer overflow in silclog.c.
7656 * Updated config.sub and config.guess on the distribution tree.
7658 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7660 * Added command lagging support in server. Client may execute
7661 commands now only once in two seconds.
7663 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7665 * Optimized packet reception. MAC computation and checking is now
7666 also more optimized. A lot previously duplicated code is now
7667 used as generic by both client and server.
7669 * Fixed key pair generation in clientutil.c
7671 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * Added into lib/silccore/silcbufutil.[ch] new function;
7674 silc_buffer_realloc.
7676 * Moved generic packet sending/encryption functions to
7677 lib/silccore/silcpacket.[ch] from client and server. Some
7678 rewriting of the functions.
7680 * Moved all generic packet reception/decryption functions to
7681 lib/silccore/silcpacket.[ch] from client and server. The
7682 packet processing is now much cleaner in both client and server.
7683 These were major changes in both client and server.
7685 * Created many common functions in server to do packet sending.
7686 Previously code were duplicated a lot, this has been removed
7689 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7691 * Rewrote major parts of the ID cache system. Don't know
7692 whether it is better now or not but at least the API is more
7695 * Major rewrite on ID cache stuff on client because of the ID
7696 cache API changes. Added idlist.c to client.
7698 * Also major rewrite on ID cache stuff on server as well.
7699 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7700 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7701 in hand, instead they are all put into the ID cache system now.
7702 All server_idlist_* routines uses ID cache now instead of
7703 traversing its own lists (those lists does not exist anymore).
7704 SilcIDList though still exists. Also, SilcXXXEntry's are
7707 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7709 * Finally made the SKE implementation compliant to the protocol
7710 specification. All mp integers are now binary encoded as
7711 opposed being HEX encoded.
7713 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7716 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7717 functions: silc_[encode/decode]_pem. Also added function
7718 silc_encode_pem_file to PEM encode with newlines ('\n') for
7721 * SILC public keys are now encoded either PEM or binary. Same
7722 option is for private keys as well. By default private keys
7723 are binary encoded and public keys PEM encoded. Silly HEX
7724 encoding were removed.
7726 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7727 function to create fingerprints.
7729 * Fixed a bug in SHA1; does not change the original data anymore.
7731 * Partly implemented INFO command on client and server side.
7732 Fixed CLEAR command. Changes to SERVER command; show current
7733 server(s) when giving command without arguments. Added
7734 VERSION command to client.
7736 * Added check to server that unregistered connections cannot
7737 execute commands (unless it is specificly allowed).
7739 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7741 * Fixed screen refresh.
7743 * Fixed channel joining bug from client. On some circumstances
7744 client tried to join to a channel it had already joined.
7746 * Added public key verification process into client's protocol.c.
7747 The client now verifies the public key from user and saves
7748 it into ~./silc/serverkeys/ directory.
7750 Added into: clientutil.[ch]: silc_client_verify_server_key.
7752 * Changed SKE protocol's silc_ske_initiator_finish function
7753 to accept callback function that verifies the received public
7754 key. Removed old silc_ske_verify_public_key function.
7756 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7758 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7759 silc_pkcs_private_key[_data]_set.
7761 * Made the password and public authentication more cleaner in
7762 server's protocol.c.
7764 * Removed historic and obsolete protocol `channel_auth' from
7765 both client and server.
7767 * Removed wrong way of sending command status messages from
7768 server to client in server's command.c. The old way violated
7769 protocol specification.
7771 Changes to silccore/silccommand.[ch]: removed
7772 silc_command_encode_status_payload -> not needed anymore,
7773 changed silc_command_encode_payload_va to accept extra
7774 argument on variable argument list. The argument type must
7775 now be provided to the function. Also, added new function:
7776 silc_command_encode_reply_payload_va which is same as
7777 normal command_encode_payload_va except command status type
7778 is provided as extra argument.
7780 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7782 * Added ~./silc directory handling. The directory includes the
7783 public and private keys for the client.
7785 Added silc_client_check_silc_dir, silc_client_create_identifier
7786 and silc_client_load_keys.
7788 * Implemented SILC protocol compliant public key. Added public
7789 and private key saving to and loading from files.
7791 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7792 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7793 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7794 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7795 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7797 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7798 silc_pkcs_load_[public/private]_key.
7800 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7802 * Added silc_server_get_route (route.[ch]) to get connection
7803 data for the fastest route for given ID.
7805 * Implemented INVITE command on client and server. The command
7806 were re-defined in the SILC Protocol Specification and the
7807 implementation now complies with the specification.
7809 * Implemented PING command on client and server.
7811 * Implemented NAMES command on client and server. The server side
7812 supports currently only normal server not router server yet.
7813 Some changes to NAMES definition in SILC protocol specification.
7815 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7817 * Implemented LEAVE command on client and server.
7819 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7820 again. This change was made to the protocol as well. Server
7821 should not violate the protocol specification anymore.
7823 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7825 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7826 was tested. SOCKS4 was not but should work anyway.
