1 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Merged a long nickname (127 characters long) crash bugfix from
4 Irssi CVS tree. Affected file irssi/src/core/misc.c.
6 * Merged a freed memory reference bugfix from Irssi CVS tree.
7 Affected file irssi/src/core/commands.c.
9 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
11 * Added the server's public key sving and verification to the
12 server when performing the SKE. This was missing and the
13 remote server's (or router's) public key was accepted without
14 checking whether we have it previously or trust it at all.
15 Affected file silcd/protocol.c.
17 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
19 * Check in the silc_server_timeout_remote if protocol is active
20 and make sure that the protocol's final callback is called so
21 that all memory if freed. Affected file silcd/server.c.
23 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
25 * silc_server_whois_send_reply crashed the server if the nickname
26 was 127 characters long. Affected file silcd/command.c.
28 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
30 * Added sanity check to the silc_server_new_client. If the hostname
31 is provided inside username then check that the provided hostname
32 really is the same as the resolved one. If the hostname was not
33 resolved then check it from the public key. Affected file is
34 silcd/packet_receive.c.
36 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
37 if the server disconnected us and the connection is not valid
38 anymore. Affected file irssi/src/silc/core/silc-channels.c.
40 * Moved the silc_client_[chmode|chumode|chumode_char] away from
41 the library to the lib/silcutil/silcutil.[ch].
43 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
45 * Close log file after open. Affected file
46 lib/silcutil/silclog.c.
48 * Check whether sock == NULL in silc_client_send_packet and return
49 if it is. Affected file lib/silcclient/silcclient.c.
51 * Check rec->entry == NULL in the Irssi SILC Client before
52 sending the channel message. Affecte file is
53 irssi/src/silc/core/silc-servers.c.
55 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
57 * Merged a splitted window bugfix from Irssi CVS tree. The
58 affected file is irssi/src/fe-text/textbuffer-view.c.
60 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
61 It did not print nickname.
63 * Improved the distributions system a bit.
65 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
67 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
68 irssi/src/fe-text/gui-window.c.
70 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
71 to in-active server. The affected file is
72 irssi/src/silc/core/client_ops.c.
74 * Resolve the client in USERS command reply if the entry does
75 not have username resolved. The affected file is
76 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
77 command to WHOIS command to really resolve stuff. The USERS
78 is not used any more in any critical section so WHOIS can
79 be used even though it might be slower than IDENTIFY.
81 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
84 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
86 * Changed the protocol API a bit more consistent in the
87 lib/silccore/silcprotocol.[ch].
89 * Changed the following headers to ROBODoc format:
91 lib/silccore/silcpayload.h
92 lib/silccore/silcprotocol.h
93 lib/silccore/silcsockconn.h
95 All core library headers are now formatted.
97 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
99 * Fixed a bug in Irssi SILC client; do not show that you are
100 server/router operator if you really are not. Affected file is
101 irssi/src/silc/core/client_ops.c.
103 * Renamed silc_command_free_payload to silc_command_payload_free.
104 Affected file lib/silccore/silccommand.h
106 * Added silcmath.h to include the prototoypes of various routines
107 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
110 * Changed the following headers to ROBODoc format:
112 lib/silccore/silcchannel.h
113 lib/silccore/silccommand.h
114 lib/silccore/silcid.h
115 lib/silccore/silcidcache.h
116 lib/silccore/silcmode.h
117 lib/silccore/silcnotify.h
118 lib/silccore/silcpacket.h
119 lib/silcmath/silcmath.h
121 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
123 * Added checking to the server code not to start the server if
124 ciphers and stuff are not configured properly. Affected files
125 silcd/serverconfig.[h] and silcd/server.c.
127 * Changed the layout of the header files of the public interfaces
128 in the SILC libraries. The new layout supports ROBODoc
129 documentation tool (and some others) so that it is easy to create
130 a library reference manual. All the other headers and source
131 code must still follow the CodingStyle document. Also source
132 code must not include these ROBODoc stuffs, only the headers.
133 Furthermore, all public interface headers must now be named
134 by using `silc' prefix, example: silcapi.h, silccipher.h.
135 Some files were renamed due to this. All the other headers
136 must not be used as public interfaces. I will update the
137 CodingStyle document later. Changed following headers, so far:
139 lib/silcclient/silcapi.h
140 lib/silccore/silcauth.h
141 lib/silccore/silcprivate.h
142 lib/silccrypt/silcdh.h
144 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Removed silc_client_packet_send_flush from the client library
149 as it is not needed. Affected file lib/silcclient/client.[ch].
151 * Added printing of message of unresolved authentication method
152 to the Irssi SILC client. Added it to the module formats.
153 Removed the same message from the client library.
155 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
157 * Added new distribution feature, DISTLABEL. Every distribution
158 can define own preprocessor label that can be used in the
159 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
160 file distributions, acconfig.h.pre and prepare.
162 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
164 * Added Makefile.defines_int to include the actual definitions
165 for Makefile.defines.in. Tested the new distribution system,
166 created distributions and tested installation.
168 * Added AWAY message printing to the Irssi SILC client. Added
169 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
171 * Added SCONNECT command to call the SILC's CONNECT command.
172 Cannot use CONNECT directly since Irssi uses that internally.
173 Affected file irssi/src/silc/core/silc-servers.c.
175 Added ACTION local command. It is same as ME command but takes
176 the channel as mandatory argument.
178 Rewrote some of the Irssi's help files to suite for SILC
181 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
183 * Added Makefile.defines[.in] that should for now on be included
184 in all Makefile.am file in the source tree. That file includes
185 all common compilation definitions for SILC source tree.
187 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
189 * Minor changes to the ./prepare script to change the package
190 name according the distribution name to the configure.in.
192 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
194 * Created new distribution system. Added file `distributions'
195 that defines all the distributions that can be created out of
196 the SILC source tree. The ./prepare script now reads that
197 file to determine how to prepare the distributions. The
198 first argument to the ./prepare is the name of the distribution
199 and second is the version of the distribution. If given
200 without arguments it creates the default (toolkit) distribution
201 with the default version (defined in ./prepare).
203 All Makefile.am files that are subject to the distributions
204 are now named as Makefile.am.pre. These are ./Makefile.am
205 and lib/Makefile.am. Others may be changed later.
207 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
209 * Added invite list, ban list, some key management and connection
210 error message printing to module formats in the Irssi SILC client.
212 * Added new silc_client_set_away_message to set the away message
213 that is back to the person who sent private message. The
214 affected file lib/silcclient/silcapi.h and the
215 lib/silcclient/client_prvmsg.c.
217 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
219 * Fixed the private message sending in the Irssi SILC client,
220 added local command KEY to the Irssi SILC client.
222 Added key management and key agreement message formats to the
223 irssi/src/fe-common/silc/module-formats.[ch].
225 Added USERS (alias WHO) printing, server/router operator
226 indication and LIST command printing to the module formats.
228 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
230 * Fixed channel joining notify handling, cumode notify handling
231 from Irssi SILC client.
233 * Added SILC specific module-formats to the Irssi SILC client so
234 that SILC specific message hilighting, colors etc is possible.
235 Affected file irssi/src/fe-common/silc/module-formats.[ch].
237 Added channel mode, channel user mode, actions, notices,
238 whois and whowas printing to the the module-formats.c.
240 * Fixed a bug in channel deletion in the server. The channel
241 is not left to the cache even if the channel founder auth mode
242 is set when there are no users anymore on the channel. Affected
245 * The silc_net_localhost now resolves the entire hostname including
246 the domain name. Affected file lib/silcutil/silcnet.c.
248 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
250 * Changed the ask_passphrase client operation to be ascynchronous.
251 It has now a completion callback and a context that the
252 application must call after it has got the passphrase from
253 the user. Affected files lib/silcclient/silcapi.h,
254 lib/silcclient/protocol.c, lib/silcclient/command.c and
257 Added SilcAskPassphrase callback that the application calls
258 to deliver the passphrase to the library.
260 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
261 The public key verification and especially a certificate
262 verification is asynchronous procedure.
264 Added new SILC_SKE_STATUS_PENDING status to indicate the
265 request is pending and a callback will be called to finalize
268 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
269 indicate that remote end did not send its public key (or
270 certificate), even though we require it. Added check for this
271 condition in the SKE. This was a security bug, now fixed.
273 Defined new SilcSKEVerifyCbCompletion callback that is called
274 when the verification process is completed.
276 The affected files lib/silcske/silcske_status.h and
277 lib/silcske/silcske.[ch].
279 * Changed the verify_public_key client operation to be async
280 as well. Defined SilcVerifyPublicKey callback that is used to
281 indicate the success of the public key verification process.
283 Changed the server and client to use the new async client
286 * Changed the Irssi SILC client's internal scheduler to be called
287 twice as many times as it used to be. As a result the client
288 should be a bit faster now. Affected file is
289 irssi/src/silc/core/silc-core.c.
291 * Added support to Irssi SILC client of asynchronous public key
292 verification and passphrase inquiry. Affected file is
293 irssi/src/silc/core/silc-core.c.
295 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
297 * Do not say "You have left channel %s" in client library.
298 Moved it to the application. Affected files are
299 lib/silcclient/command.c and silc/client_ops.c.
301 * Fixed silc_client_get_clients. Command context was not
302 duplicated and was freed memory in the callback. Affected
303 file lib/silcclient/idlist.c.
305 * Do not say "you are now talking..." on JOIN command in the
306 client library. The appliation must handle it.
308 * Do not say ".. changed topic to" in command reply in the
309 client libary. The application must handle it.
311 * Fixed TOPIC command sending in the client library.
313 * Fixed a memory leak in silc_client_command_free in the file
314 lib/silcclient/command.c.
316 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * Imported a modified version of Irssi client to the source tree.
319 The Irssi will be used to create a new client called
320 Irssi SILC. Imported to irssi/.
322 Added silc_core_init_finish function to the Irssi. Affected
323 file irssi/configure.in.
325 A lot changes in the Makefile.ams around the irssi tree.
327 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
329 * Do not rehash if the new size is same as the old size of the
330 hash table, in the silc_hash_table_rehash*. The affected file
331 lib/silcutil/silchashtable.c.
333 * Replaced hash_table_del_by_context calls from the server
334 (when channel->user_list and client->channels) to the
335 hash_table_del as it is sufficient and faster.
337 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
339 * Added silc_hash_table_list, silc_hash_table_get and the
340 SilcHashTableList structure to provide an alternative way to
341 traverse the hash table. The affected files are
342 lib/silcutil/silchashtable.[ch].
344 * Changed the server's idlist routines to use the hash table
345 routines to optimize the code.
347 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
349 * Replaced the client entry's `channel' list and channel entry's
350 `user_list' list to hash tables for optimized lookup. Changed
351 the code to use the hash table interface around the code.
352 Affected file lib/silcd/idlist.[ch].
354 * Added `auto_rehash' boolean argument to the function
355 silc_hash_table_alloc to indicate whether the hash table should
356 auto-rehash when it thinks is appropriate time. It will
357 increase the hash table size if the there is twice as much
358 entries in the table than the size of the table, and will
359 decrease the size if there are twice as less entries than
360 the size of the table.
362 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
364 * Fixed silc_xxx_get_supported to not crash at some circumstances.
366 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
368 * silc_idcache_purge_by_context deletes the entry now by context
369 as it is supposed to do. Affected file lib/silccore/idcache.c.
371 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
372 client is not anymore valid (WHOWAS givens the info) and not
373 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
375 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
377 * Removed the `data' and `data_len' arguments from the ID Cache
378 interfaces and added `name' argument. ID Cache does not handle
379 anymore the binary data only a names associated with given ID.
381 * When hashing a Client ID with silc_hash_id the entire ID is
382 not hashed anymore, instead only the hash of the Client ID is
383 hashed. This way we can access the Client ID from the cache
384 with Client ID but with the hash of the ID (which is a hash of
385 the nickname) as well without any difference in performance.
387 Added also silc_idcache_find_by_id_one_ext to do one on one
388 searching when we have the actual ID. Added also function
389 silc_hash_client_id_compare. The affected files are
390 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
392 * When hashing the name associated with a ID it is always done
393 in lowercase. This way we can access the cache without worrying
394 about case-sensitivity, even though, for example nicknames are
397 * Fixed a bug in server with channel message sending. It put
398 wrong ID type as destination ID. The affected file
401 * silc_idcache_del_by_context now deletes from all hash tables
402 by context. Affected file lib/silccore/idcache.c.
404 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Changed the client library to use the new ID Cache interface.
407 Changes around the source tree.
409 * Added silc_hash_table_rehash_ext to rehash with specific
410 hash function. Affected file lib/silcutil/silchashtable.[ch].
412 * Added silc_hash_string_compare to compare two strings in the
413 hash table. Affected file lib/silcutil/silcutil.[ch].
415 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
417 * Added new function silc_idcache_del_by_context into the
418 lib/silccore/idcache.[ch].
420 * Changed the server's ID list routines to use the new ID Cache
421 interface. Changes around the source tree.
423 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
425 * Added silc_hash_table_del[_by_context]_ext functions in to the
426 lib/silcutil/silchashtable.[ch].
428 Removed silc_hash_table_find_all* routines and added new
429 silc_hash_table_find_foreach to replace them.
431 Added silc_hash_table_replace_ext function as extended
432 replacing function. Separated the simple hash table interface
433 from the extended hash table interface in the file
434 lib/silcutil/silchashtable.h.
436 * Fixed minor bugs and changed it to use some of the new
437 hash table functions in lib/silccore/idcache.c
439 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Added new function silc_hash_table_find_all to return all keys
442 in the hash table by the specified key. As the hash table is
443 collision resistant it also makes it possible to have several
444 duplicate keys in the hash table. This function may be used to
445 find all of the keys from the hash.
447 Added user_context arguments to the SilcHashFunction,
448 SilcHashCompare and SilcHashDestructor to deliver user specified
451 Added new fuctions silc_hash_table_find[_all]_ext to do
452 extended lookup with specified hash and compare functions and
453 specified user contexts.
455 Added new function silc_hash_table_add_ext to add the key
456 with specified hash function and user context.
458 Added new function silc_hash_table_foreach to traverse all
459 entrys in the hash table. Added SilcHashForeach callback
462 Added new function silc_hash_table_del_by_context to delete
463 the entry only if the context associated with the key matches.
465 Affected files are lib/silcutil/silchashtable.[ch].
467 * Removed silc_hash_[server/client/channel]_id and added just
468 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
469 silc_hash_id_compare to compare two ID's using as the hash table
470 comparison function. Added also silc_hash_data to hash
471 binary data and silc_hash_data_compare to compare it.
473 * Removed silc_idlist_find_client_by_hash as it is not needed
474 anymore. Affected file silcd/idlist.[ch].
476 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
477 to use internally the SilcHashTable. The new ID Cache is a lot
478 faster than the old one. Some of the ID Cache interface was also
479 rewritten and obsolete and stupid functions were removed.
481 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
483 * Added entry_count field to the SilcHashTable to keep the number
484 of the entries in the table. Implemented the function
485 silc_hash_table_rehash. Added new function
486 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
488 Fixed a minor bug in silc_hash_table_free.
490 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
491 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
492 into the lib/silcutil/silcutil.[ch].
494 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
496 * Implemented a collision resistant hash table into the
497 lib/silcutil/silchashtable[ch]. See the header and the source
498 for the SilcHashTable API.
500 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
502 * Merged dotconf version 1.0.2 into lib/dotconf.
504 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
506 * Do not compile anything in lib/silcsim/* if the SIM support
507 is not enabled. The tree should now compile without problems
510 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
512 * Compiled the SILC under cygwin. Compiled and tested briefly
513 without problems. More tests needed. The SIMs didn't compile
516 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
518 * Fixed possible crash in silc_get_username in the
519 lib/silcutil/silcutil.c.
521 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
523 * Fixed a va_arg in silc/client_ops.c.
525 * Oops, RC5 routines were named AES and caused some problems
526 when not using SIM's. Affected file lib/silccrypt/rc5.c.
528 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
530 * Added new SilcIDIP structure into the lib/silccore/id.h and
531 replaced the old `ip' fields from all SILC ID's to that type.
532 This is a step towards IPv6 support.
534 The silc_id_get_len takes now the ID as an extra argument.
535 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
536 both IPv4 and IPv6 based ID's.
538 The affected files are lib/silccore/id.[ch] and other files
539 around the tree using these routines.
541 * Removed the ID length arguments in server from various
542 silc_server_send_notify_* routines -> they are not needed
545 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
547 * Fixed memory leak in silc_encode_pem_file in the file
548 lib/silcutil/silcutil.c.
550 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
552 * Check minor version as well in the SKE. Affected files are
553 silcd/protocol.c and lib/silcclient/protocol.c.
555 * Added --identifier option to the server so that an identifier
556 can be when creating the public key for the server. Affected
557 file is silcd/silcd.c.
559 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
560 lib/silccrypt/silcpkcs.c.
562 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
564 * Register default ciphers and stuff when using -C option with
565 the server. Affected file sildc/silcd.c.
567 * Put back the servers public key filename format, it is better
568 than the new one. For now, the client keys are saved with the
569 new filename format. The affected file silc/client_ops.c.
571 * Implemented the Cipher API for the rest of the ciphers that
572 did not implement it or implemented it the wrong way.
574 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
576 * Register default ciphers and stuff when using the -S option
577 in the client. Affected file silc/silc.c. Same also when
578 creating new key pair with -C option.
580 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
582 * Fixed the silc_verify_public_key client operation function to
583 save the public keys differently. The fingerprint is now
584 used as filename and not the hostname. This way also the
585 client keys are saved uniquely and not with hostnames. The
586 affected file is silc/client_ops.c.
588 * Trimmed the silc_hash_fingerprint function to remove extra
589 whitespaces from the end of the fingerprint. The affected
590 file is lib/silccrypt/silchash.c.
594 * Added silc_cipher_register_default function to register all
595 default ciphers. It can be used when configuration files
596 does not exist and the application does not want any specific
597 ciphers in any specific order.
599 The SilcDList is now used as silc_cipher_list dynamically
600 allocated cipher list. Removed the static list all together
601 and now all ciphers must be allocated to the dynamic list.
602 The silc_cipher_alloc routine was changed to check only the
605 All silc_cipher_* routines that used to return int returns
608 The affected files lib/silccrypt/silccrypt.[ch].
610 * The same thing was done to silc_hash_* as for silc_cipher_*
611 routines. Affected files lib/silccrypt/silchash.[ch].
613 * The same thing was done to silc_pkcs_* as for silc_cipher_*
614 routines. Affected files lib/silccrypt/silcpkcs.[ch].
615 Added also silc_pkcs_[un]register[_default] functions.
616 Removed the data_context from the PKCS API.
618 * Added silc_hmac_register_default function to register default
619 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
620 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
621 to unregister all hmacs at once.
623 * Register the default ciphers, hash functions, PKCSs and HMACs
624 if client's configuration file does not exist. The affected
627 * The client did not load the hash functions from the SIM
628 modules at all. Added support for this. Affected file is
631 * When decoding public key with silc_pkcs_public_key_decode, check
632 the supported algorithm only if PKCS are registered. Affected
633 file lib/silccrypt/silcpkcs.c. The same was done with the
634 silc_pkcs_private_key_decode.
636 * Fixed the SILC List routines to keep the list always in order.
637 It used to change the list's order when traversing the list but
638 not it preserves the order. Affected file lib/trq/silclist.h.
640 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
642 * Added the client library to use the SilcSocketConnection's
643 reference counter (by silc_socket_dup) to prevent the bug that
644 the socket object may be freed underneath async operation.
646 * The name resolv library checking fixes in the configure.in.pre.
649 * Created new version of the protocol drafts for future
650 development. The -03 drafts are the ones that will be changed
651 in the trunk now and the -02 will remain as they are.
653 * Send list of CUMODE notifys to the router when announcing
654 the channel users to the router. Affected file silcd/server.c.
655 If the router receiving channel founder CUMODE for a channel
656 that already has channel founder it will send CUMODE notify
657 to the sender to remove the channel founder rights from the
658 announced client. Affected file silcd/packet_receive.c.
660 * The CUMODE notify may now use Server ID as well as the entity
661 who changes the mode. Updated protocool specs.
663 * Updated INSTALL and README files.
665 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
667 * New web pages in the http://silc.pspt.fi. The pages was
672 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
674 * Implemented the [DenyConnectin] config section in the server.
675 Added silc_server_config_denied_conn to check whether incoming
676 connection is denied. Affected file silcd/serverconfig.[ch].
678 * Do not check the ports when checking the incoming configuration
679 data if the port is 0, meaning any. Affected file is
680 silcd/serverconfig.c.
682 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
684 * Fixed buffer overflow in silc_string_compare in the file
685 lib/silcutil/silcutil.c.
687 * Fixed double free in silc_server_command_leave in the file
690 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
692 * Fixed the version checking in the server. Affected file is
695 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
697 * Fixed the configuration data fetching when accepting new
698 connections in the server. Affected file silcd/server.c.
700 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
702 * Added `sender_entry' argument to the function
703 silc_server_packet_relay_to_channel so that we can check
704 whether some destination actually belongs to the same route
705 the sender belongs (ie, we must not resend the packet to the
706 sender). Affected file silcd/packet_send.[ch].
708 * Added `servername' field to the SilcClientEntry in the server
709 to hold the name of the server where client is from. Affected
710 file is silcd/idlist.h.
712 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
714 * Moved the channel message encrypting in the router betwen
715 router connections from silc_server_channel_message to the
716 silc_server_packet_relay_to_channel since we want to check
717 whether we have anybody channel before encrypting anything.
718 Affected files silcd/packet_[receive/send].c.
720 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Fixed the [AdminConnection] server config section to support
723 multiple entries. Affected file silcd/serverconfig.c.
725 * Added support into the server to check the validity of the
726 incoming connection before executing any KE or authentication
729 * The connection configuration is now saved to the KE and
730 connection auth protocol contexts and not fetched anymore in
731 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
733 * The local hosts listenning address and port is also resolved
734 now when starting the server. We want to have the socket object
735 to include the real address and port for the listener. Added
736 new function silc_net_check_local_by_sock into the files
737 lib/silcutil/silcnet.[ch].
739 * Fixed a broadcast bug in server -> do not broadcast if we
742 * Fixed a routing bug. Do not route broadcast packets ever.
743 Broadcast packets must be processed always and not routed since
744 they may be destined to some other host than yourself and thus
745 would get routed without no good reason. Affected file is
748 * Added function silc_server_config_is_primary_route to check
749 whether primary router connection has been configured (a router
750 configuration that we are initiating). If there is not, we
751 will assume that there is only two routers in the SILC network
752 and we will use the incoming router connection as our primary
753 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
755 * Changed the order of the broadcasting. Broadcast _after_ the
756 packet has been processed not before. Affected file is
759 * Fixed a [ClientConnection] parsing bug. The port was never
760 parsed correctly thus resulting to port 0. Affected file
761 silcd/serverconfig.c.
763 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
764 argument and did not set the broadcast packet flag. Affected
765 file silcd/packet_send.c. Fixed same bug in the function
766 silc_server_send_notify as well.
768 * If we receive NEW_ID packet for our own ID in the server, ignore
771 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
775 * Removed the nickname from the Private Message Payload.
776 Updated the code and the protocol specs.
778 * Updated protocol specs for submitting to the IETF.
780 * Tweaked the Random Number Generator a bit. Affected file
781 lib/silccrypt/silcrng.c. Exported a new function
782 silc_rng_[global]_add_noise which can be used to add more
785 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * Do not parse packets with different timeout when protocol
788 is active -> may cause problem with rekey. Affected file
791 * When server receives signoff notify it must not create
792 new channel key if the client is on any channels since the
793 sender of the signoff notify will create it.
795 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
797 * Added printing of error messages during SKE protocol from the
798 failure packet sent by server during SKE. Affected file
801 * Removed the client's failure_callback handling with timeout
802 and handle it immediately when received.
804 * The SKE library returned wrong type in SUCCESS and FAILURE
805 packets. They must be 32 bit MSB not 16 bit MSB.
807 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * Ok, rewrote the logic of the re-key and now it seems to work.
810 I tested it on high traffic with frequent re-keys without
811 problems. Added hmac_receive (and renamed hmac to hmac_send)
812 in SilcClientConnection in lib/silcclient/client.h and
813 in SilcIDListData in silcd/idlist.h. Also, removed the
814 SilcPacketParserContext's cipher and hmac fields as they are
815 not needed anymore and actually caused some problems when
816 the ciphers and hmac's changed underneath the packet parser.
818 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
820 * If re-key protocol is active then process the incoming packets
821 synchronously since we must assure that icoming packets encrypted
822 with the old key is processed before the new keys is set to
823 use. This is true other packets than for REKEY packets.
824 Affected file silcd/server.c. The same was done to client library
825 as well, affected file lib/silcclient/client.c.
827 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * Fixed bug in client and server to accept the force send if
830 the packet is send from silc_[server/client]_packet_process
831 function. Otherwise the packets are never delivered, oops.
833 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
835 * Disable force sending of packets when REKEY protocol is active.
836 We must assure that no packet is sent directly when rekey is
837 performed. All packets must be sent through packet queue.
838 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
839 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
840 function is silc_[server/client]_packet_send_real to check
843 * Replaced the SIM paths from example config files to
844 /usr/local/modules. Also, make install creates now
845 /usr/local/silc/logs directory to hold all the SILC server
848 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
850 * Made the configure.in.pre work on Solaris. Patch by salo.
852 * Made all ciphers compatible with non-x86 machines. Defined
853 CBC mode macros into lib/silccrypt/ciphers_def.h.
855 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
857 * Fixed the make install.
859 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
861 * When MAC computation fails the silc_packet_decrypt returned 0
862 even though it was supposed to return -1. Fixed this. The
863 affected file is lib/silccore/silcpacket.c.
865 * Do not replace the config files in /etc/silc (in make install)
866 if they already exist. Affected file ./Makefile.am.
868 * Do not send re-key packets immediately but through packet queue.
869 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
871 * Changed silc_net_check_host_by_sock to return FALSE if the
872 IP/DNS could not be resolved. Though, it returns the IP address
873 now even if it could not resolve it (but returns also FALSE).
874 Affected file lib/silcutil/silcnet.[ch].
876 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
878 * Added silc_pkcs_decode_identifier to decode the public key's
879 identifier. Affected file lib/silccrypt/silpkcs.[ch].
880 Added also silc_pkcs_free_identifier. Added also new context
881 SilcPublicKeyIdentifier.
883 * Added -S option to the silc client. It is used to dump the
884 contents of the specified public key file.
886 * Changed the PKCS api to return the public key length when
887 setting the public key.
889 * Fixed a fatal bug in the public and private key file loading.
890 Affected file lib/silccrypt/silcpkcs.c.
892 * Execute the packet parsing for client with zero (0) timeout
893 if the protocol is active. Affected file silcd/server.c.
895 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
897 * Made the key generation options to the silcd program. Added
898 -C option, equivalent to client's option.
900 * Added new [ServerKeys] config section to the server. It
901 configures the server's public and private key.
903 * Defined generic Public Key Payload into the protocol
904 specification to send specific type of public keys and
907 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
908 public key or certificate.
910 * Implemented the GETKEY command to the server and to the
911 client library and on user interface.
913 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
915 * Made preliminary `make install' work.
917 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
919 * Added SilcServerRekey context into silcd/idlist.h.
921 * Added the PFS support as defined in the specification to the
922 SKE protocol. Affected files lib/silcske/*.c.
924 * Added `ske_group' field to the SilcServerRekey context to hold
925 the number of the SKE group that is used with PFS in re-key.
926 Affected file silcd/idlist.h.
928 * Added PFS re-key support to the server. Affected file is
931 * Added silc_protocol_cancel to cancel execution of the next
932 state of the protocol. Affected file is
933 lib/silccore/silcprotocol.[ch].
935 * Added the re-key support with and without PFS to the client
936 library. Re-key is performed once in an hour, by default.
938 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
939 Added silc_client_rekey_callback and silc_client_rekey_final.
940 Affected files are lib/silcclient/protocol.[ch] and
941 lib/silcclient/client.[ch].
943 * Removed the `hmac_key' and `hmac_key_len' fields from the
944 SilcClientConnection structure; not needed. Affected file is
945 lib/silcclient/client.h.
949 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
951 * Do not ask whether user wants to use the negotiated private key
952 for private messages, just use it. Affected file is
953 silc/local_command.c.
955 * Added `send_enc_key' and `enc_key_len' fields to the
956 SilcIDListData structure since they are needed in the re-key
957 phase. Affected file is silcd/idlist.[ch].
959 * Implemented the simple re-key protocol into the server.
960 Affected files silcd/server.c and silcd/protocol.[ch]. The
961 re-key will be performed once in an hour, by default.
963 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
964 Added silc_server_rekey, silc_server_rekey_callback and
965 silc_server_rekey_final.
967 * Removed Tunneled flag from the protocol. Updated the code
968 and the specifications.
970 * Adde `pfs' field to the SilcIDListData to indicate whether
971 the PFS is to be performed in the re-key. Affected file is
974 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
976 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
977 int64 of at least the xintXX size. If void * is less that 4
978 bytes uint32 * will be used. Defined bool as boolean.
980 * Changed _ALL_ unsigned long and unsigned int to uint32,
981 unsgined short to uint16 in the source tree.
983 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
984 not handle clients that has entry->data.registered == FALSE.
985 They are not in the network anymore. Affected file is
988 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
990 * Implemented the sending of the SERVER_SIGNOFF notify in the
991 server. Affected file is silcd/server.c.
993 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
994 Added also silc_notify_payload_encode_args into the
995 lib/silccore/silcnotify.[ch].
997 * Implemented ther SERVER_SIGNOFF notify handling in the server.
998 Affected file silcd/packet_receive.c.
1000 * Implemented the SERVER_SIGNOFF notify handling in the client
1001 library. Affected file lib/silcclient/client_notify.c. Also,
1002 implemnted the printing of the SERVER_SIGNOFF info to the
1003 application. Affected file silc/client_ops.c.
1005 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1006 if the deleting was successful. Affected file silcd/idlist.[ch].
1008 * Added support for public key authentication in the connection
1009 authentication protocol in the client library. Affected file
1010 lib/silcclient/protocol.c.
1012 * Changed the server's silc_idlist_get_clients_by_* interface
1013 to support already allocated array so that new entries may be
1014 added to pre-allocated array. Affected file silcd/idlist.[ch].
1015 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1016 and command replies.
1018 * All command reply functions in the server now calls the
1019 pending command callback even if error occured. This way the
1020 error will be delivered to the client as well. Affected files
1021 silcd/command.c and silcd/command_reply.c.
1023 * Fixed INFO command to return local server's info if no server
1024 was provided. Affected file lib/silcclient/command.c.
1026 * Removed RESTART command for good. Updated the code and the
1029 * Rewrote parts of the task system. It is a bit simpler now.
1030 Removed unsued task priorities. The affected files are
1031 lib/silcutil/silctask.[ch].
1033 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Moved the USERS printing from the library to the application.
1036 Affected files lib/silcclient/command.c and silc/client_ops.c.
1038 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1042 * Added channel key re-key support. The re-key is perfomed
1043 only by the router and is done once in an hour. Added `rekey'
1044 field to the SilcChannelEntry in the server. Affected files
1045 silcd/server.c and silcd/idlist.h.
1047 * Added silc_task_unregister_by_context into the file
1048 lib/silcutil/silctask.[ch].
1050 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1052 * Added SILC_UMODE_GONE mode to indicate when the client is not
1053 present in the SILC network. Added also support to the local
1054 command AWAY that will set this mode. Added support of showing
1055 "xxx is gone" in WHOIS command. The USERS command shows the
1056 gone status as well.
1058 * Fixed setting server and router operator privileges in the
1059 server's UMODE command. Affected file silcd/command.c.
1061 * Merged the SKE KE1 and KE2 payloads into one payload. The
1062 new KE payload is equivalent to the old KE2 payload.
1064 Cleaned up the SKE Start Payload parsing. It now uses the
1065 simple buffer unformatting to do the parsing. A lot faster
1068 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1069 to the SKE that is used to indicate whether both of the SKE
1070 parties should perform authentication. By default only the
1071 responder performs authentication. By setting this flag also
1072 the initiator must do authentication. By default it is unset
1073 since in normal SKE case, client to server connection, only
1074 the responder should do authentication. When doing SKE between
1075 two clients both should perform authentication. Updated the
1076 code and the protocol specs.
1078 * A little fix to IDENTIFY command in the server. Search the
1079 client first by hash not nickname. Affected file is
1082 * Fixed the silc_client_close_connection to support closing
1083 the client to client connections wihtout deleting too much
1084 data. Affected file lib/silcclient/client.c.
1086 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1087 are received if protocol used to be active but is not anymore
1088 the application would crash due to NULL pointer dereference.
1089 Affected files silcd/server.c and lib/silcclient/client.c.
1091 * Added `hash' field to the SilcClientConnection to include
1092 the hash function negotiated in the SKE protocol.
1094 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1095 to set the channel founder authentication data. A client can
1096 claim the founder rights later by providing the authentication
1097 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1098 This way the channel founder can regain the channel founder
1099 privileges even it is left the channel. This works only on
1100 local server and the client must be connected to the same
1101 server to be able to regain the founder rights. Updated the
1102 protocol specs accordingly.
1104 Added support to the CMODE command in the client to set the
1105 founder auth data. Read the README to see how to set it.
1107 Added support to the CUMODE command to claim the founder
1108 rights. Read the README to see how to do it.
1110 Added support for the founder authentication to the Channel
1111 Entry in the server. Affected file silcd/idlist.h.
1113 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1114 server's CMODE command. Affected file silcd/command.c.
1116 * Added the following new functions into lib/silccore/silcauth.[ch]:
1117 silc_auth_get_method and silc_auth_get_data.
1119 * The server now saves the remote hosts public key to the
1120 SilcIDListData pointer. Affected file silcd/protocol.c.
1122 * The normal server now does not remove the channel entry from
1123 the cache if the founder authentication data is set. It used
1124 to remove it if the founder was the last one on the channel on
1125 the server and left the channel. The auth data is saved and
1126 if the channel is re-joined later the old entry is used with
1127 the old auth data. Affected files silcd/command_reply.c and
1130 * Removed the `pkcs' field from the SilcIDListData structure
1131 in the server; it is not used. Affected file silcd/idlist.h.
1133 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1135 * Fixed packet processing on slow links. Partial packets were
1136 never re-processed because the incoming data buffer was cleared
1137 by the application. Application must not directly clear the
1138 sock->inbuf, the packet processing routines handle it. Fixed
1139 this in client library and in server.
1141 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Fixed the WHOIS and IDENTIFY send reply function to really
1144 check whether to send list or just one entry. Affected file
1147 * Cleaned up the LEAVE command's channel key distribution. The
1148 affected file silcd/command.c.
1150 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1151 can enforce the channel mode as well. In that case the ID
1152 includes the ID of the server. The code now enforces the
1153 mode change if the router have different mode than the server.
1155 * The notify client operation with CMODE_CHANGE notify can now
1156 return NULL client_entry pointer if the CMODE was not changed
1157 by client. Application must check for this.
1159 * Added <Server ID> argument to INFO command to support server
1160 info fetching by Server ID.
1162 * Added silc_server_announce_get_channel_users to get assembled
1163 packets of channel users of the specified channel. Affected
1164 file silcd/server.[ch].
1166 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1167 was freed underneath the ID Cache.
1169 * Re-announce clients when the server received CHANNEL_CHANGE
1170 notify from the router. Affected file silcd/packet_send.c.
1172 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1174 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1175 crashed since it did not handle the fact that there is no cipher
1176 called "3" and didn't check the error condition. Now fixed.
1178 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1179 flag. It can be used to send message requests.
1181 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1183 * Implemented the RESTART command in the client.
1185 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1186 notice type messages. Added notice printing to the user
1189 * The channel keys are not re-generated if the channel's mode
1190 is PRIVKEY, ie private key on the channel exists. Affected
1191 files silcd/server.c and silcd/command.c.
1193 * Fixed a little bug in channel message delivery when channel
1194 private keys are set in the server. Affected file is
1195 silcd/packet_send.c.
1197 * Changed the setting on channel->on_channel = TRUE from the
1198 silc_client_save_channel_key to the JOIN command reply. The
1199 key payload is not received if the private channel key is set.
1200 Affected file lib/silcclient/command_reply.c and the
1201 lib/silcclient/client_channel.c.
1203 * When the CMODE_CHANGE notify is sent and the channel private
1204 key mode is removed the channel key must be re-generated in
1205 other cells as well. Added this support for the router in the
1206 silcd/packet_receive.c.
1208 * Added new local command NOTICE to send notice message on
1209 channel. Affected file silc/local_command.[ch].
1211 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Added new local command ME to the client. It is used to send
1214 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1215 some action. Affected file silc/local_command.[ch].
1217 * Changed channel_message and private_message client operations
1218 to deliver the message flags to the application. Added also
1219 the `flags' arguments to the silc_client_send_channel_message
1220 and silc_client_send_private_message functions. Affected file
1223 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Redefined the Private Message Payload to support private message
1226 keys and to support the new private message flags. Updated
1227 the protocol specs. Flags makes it possible to have for example
1228 CTCP style messages.
1230 * Added new type SilcPrivateMessagePayload and defined an API
1231 for it in the lib/silcclient/silcprivate.[ch].
1233 * Tested private message private keys successfully. Tested the
1234 private message key set, unset and list commands with the new
1237 * Redefined the Channel Message Payload to include the channel
1238 message flags (equal with private message flags) to support
1239 for example CTCP style messages.
1241 * Defined some of the message (for channel and private message)
1242 flags. Updated the protocol specs and added the flags to the
1243 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1245 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1247 * Added SilcKeyAgreementStatus type to the key agreement routines
1248 to indicate the current status and error if one occured.
1249 The status types are defined in the lib/silcclient/silcapi.h.
1251 * Added new local command KEY that is used to set and unset private
1252 keys for channels, set and unset private keys for private messages
1253 with remote clients and to send key agreement requests and
1254 negotiate the key agreement protocol with remote client. The
1255 key agreement is supported only to negotiate private message keys,
1256 it currently cannot be used to negotiate private keys for channels,
1257 as it is not convenient for that purpose.
1259 * Fixed a minor pending callback setting bug in the function
1260 silc_client_get_client_by_id_resolve, now the function works.
1261 Affected file lib/silcclient/idlist.c.
1263 * Added function silc_net_get_local_port to get local bound
1264 port by socket. Added to lib/silcutil/silcnet.[ch].
1266 * Added `sockets' and `sockets_count' fields to the SilcClient
1267 object. They hold the sockets of the listenning sockets in
1268 the client. Listenning sockets may be for example the key
1269 agreement server. Affected file lib/silcclient/client.[ch].
1270 Added functions the silc_client_add_socket and the
1271 silc_client_del_socket. They are exported to the application
1274 * Added ~./silc/clientkeys to support other client's public keys.
1276 * Renamed verify_server_key client operation to verify_public_key
1277 and added one argument to indicate the type of the connection
1278 (server, client etc.).
1280 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1282 * Added silc_server_connection_auth_request to handle the
1283 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1284 silcd/packet_receive.[ch].
1286 * Added silc_server_send_connection_auth_request into the
1287 silcd/packet_send.c to send the connection auth request packet.
1289 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1292 * Fixed the public key authentication in responder side in the
1293 server. The `auth_data' pointer includes the SilcPublicKey
1294 not the path to the public key. Affected file silcd/protocol.c.
1296 * Implemented the public key authentication in the initiator side
1297 in the server. Affected file silcd/protocol.c.
1299 * Removed the [RedirectClient] config section from the server
1300 configuration. Is not needed and I don't want to implement it.
1302 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1304 * Cleaned up the CMODE command in the server. It now works
1305 correctly and supports all the modes defined in the protocol.
1306 Affected file is silcd/command.c.
1308 * Added `hmac_name' field to the SilcChannelEntry in the server
1309 to hold the default HMAC of the channel. It can be set when
1310 creating the channel (with JOIN command). Affected files
1313 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1314 type to indicate the change of the current cipher and hmac
1315 on the channel. Client can safely ignore the <cipher> argument
1316 (if it chooses to do so) since the CHANNEL_KEY packet will
1317 force the channel key change anyway. The <hmac> argument is
1318 important since the client is responsible of setting the new
1319 HMAC and the hmac key into use.
1321 * Fixed the CMODE command in the client library as well.
1323 * Tested CMODE command in router environment successfully.
1325 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1327 * Show the version of the remote client (or server) when connecting
1328 to the server. It is logged to the log file. Affected file
1329 is silcd/protocol.c.
1331 * Fixed the KILLED notify handling in the client library. The
1332 client must be removed from all channels when receiving the
1335 Also, do not remove the client entry when giving the KILL
1336 command but when the KILLED notify is received.
1338 * Removed silc_idlist_find_client_by_nickname from the server.
1339 Not needed anymore. Affected files silcd/idlist.[ch].
1341 * Implemented the CHANNEL_CHANGE notify type handling to the
1342 server. Affected file silcd/server.c.
1346 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1348 * Added silc_server_send_notify_invite to send the INVITE
1349 notify between routers.
1351 * Implemented the INVITE command correctly to the server.
1353 * Implemented the INVITE notify type handling in the server.
1355 * Implemented the INVITE command to the client library and on the
1358 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1360 * Added function silc_server_get_client_resolve to find the
1361 client entry by ID from all ID lists and then resolve it
1362 (using WHOIS) if it cannot be found. Affected file is
1365 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1367 * Implemented the BAN command to the client library.
1369 * The JOIN command in the server now checks the invite list
1372 * Changed the silc_command_reply_payload_encode_va and the
1373 silc_command_payload_encode_va to support that if argument is
1374 NULL it ignores and checks the next argument. Affected file
1375 lib/silccore/silccommand.c.
1377 * Added silc_server_send_notify_ban to send the BAN notify
1378 type between routers.
1380 * Chaned the silc_notify_payload_encode to support that if
1381 argument is NULL it ignores and checks the next argument.
1382 Affected file lib/silccore/silcnotify.c.
1384 * Tested ban lists in router environment successfully.
1386 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Implemented BAN command to the server, in silcd/command.[ch].
1390 * Removed the BAN and INVITE_LIST modes from the CMODE command
1393 * Added function silc_string_match to regex match two strings.
1394 Affected files lib/silcutil/silcutil.[ch].
1396 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1398 * Redefined parts of the SilcChannelEntry in the server to support
1399 the new ban and invite lists.
1401 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1403 * Redefined the INVITE command. The same command can be used to
1404 invite individuals to the channel but also to manage the invite
1405 list of the channel (to add to and remove from the invite list).
1406 Updated the protocol specs.
1408 * Added new command SILC_COMMAND_BAN that can be used to manage
1409 the ban list of the channel. Updated the protocol specs.
1411 * Removed the channel modes: the SILC_CMODE_BAN and the
1412 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1413 in the CMODE command. The equivalent features are now available
1414 using INVITE and BAN commands. Updated the protocol specs.
1416 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1417 in the network about change in the current ban list. The notify
1418 type is not used by the client.
1420 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1421 support the invite lists.
1423 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Added new function silc_string_regexify that converts string
1426 including wildcard characters into regex string that can
1427 be used by the GNU regex library. Added into the file
1428 lib/silcutil/silcutil.[ch].
1430 Added silc_string_regex_combine to combine to regex strings
1431 into one so that they can be used as one regex string by
1432 the GNU regex library. Added into the file
1433 lib/silcutil/silcutil.[ch].
1435 Added silc_string_regex_match to match two strings. It returns
1436 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1438 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * Imported GNU regex to the soruce tree into lib/contrib.
1441 Fixed some compiler warning from the regex.c.
1443 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1445 * Fixed MOTD command in the server to work in router environment.
1447 * Fixed the MOTD command in the client library to support
1448 the server argument in the command.
1450 * Added `nickname_len' argument to the silc_idlist_add_client
1451 in the server, as the `nickname' argument may be binary data
1454 * Added silc_idlist_get_channels to return all channels from
1457 * Implemented LIST command to the server. Affected file is
1460 * Implemented the LIST command to the client library and on the
1463 * Added [<user count>] argument to the LIST command reply.
1464 With private channels the user count is not shown.
1466 * Updated TODO and README.
1468 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1470 * The client entry's data.registered must be TRUE even with
1471 global client entry on global client list. The data.registered
1472 is used to check whether the client is anymore in the network,
1473 for example with WHOWAS command so it must be valid.
1475 * Fixed the WHOWAS command in the server. It now actually works
1476 in router environment. Added function into silcd/command_reply.c
1477 silc_server_command_reply_whowas_save.
1479 * Added silc_idlist_purge function to the silcd/idlist.c
1480 to periodically purge the ID Cache.
1482 * Fixed INFO command in the server. It works now in router
1483 environment. Added <server name> argument to the INFO command
1484 reply. Updated the protocol specs.
1486 * Fixed minor bug in silc_idcache_purge to not purge if the
1487 expire value is zero.
1489 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1490 they were buggy because of the WHOWAS information.
1492 * Fixed local command MSG to handle the async resolving of
1493 the remote client properly. It used to fail the first MSG.
1494 Affected file silc/local_command.c.
1496 * Added `data_len' field to SilcIDCache context.
1498 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * Update TODO. Todo in commands in the server.
1502 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1504 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1505 used by routers as broadcast packet to inform other routers
1506 about the changed user mode.
1508 Implemented the notify handling in the server. Affected file is
1509 silcd/packet_receive.c. Added the function
1510 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1512 * Added new generic Channel Payload and deprecated the New Channel
1513 Payload. The New Channel Payload is now the generic Channel
1516 * Added new argument `mode' to the silc_server_send_new_channel
1517 as it is required in the Channel Payload now.
1519 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1520 and created a new and real SilChannelPayload to represent the
1521 new generic Channel Payload. Implemented the encode/decode
1522 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1524 * Added silc_server_get_client_channel_list to return the list
1525 of channels the client has joined for WHOIS command reply.
1526 Affected file silcd/server.[ch].
1528 * Implemented the channel list sending in the WHOIS command reply
1529 in server and in the client.
1531 Implemented the channel list displaying on the user interface
1532 as well. Affected file silc/client_ops.c.
1534 * Added silc_channel_payload_parse_list to parse list of Channel
1535 Payloads. It returns SilcDList list of SilcChannelPayloads.
1536 Client for example can use this function to parse the list of
1537 channels it receives in the WHOIS command reply. The caller
1538 must free the list by calling silc_channel_payload_list_free.
1539 Affected files lib/silccore/silcchannel.[ch].
1541 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1543 * Added one new argument <user mode> to the WHOIS command reply
1544 to return the mode of the user in SILC. Updated the protocol
1547 Implemented it to the server and client.
1549 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1551 * Fixed the mode printing on the user interface on joining.
1552 Affected file silc/client_ops.c.
1554 * Implemented the UMODE command and user modes in general to the
1555 client library and to the user interface.
1557 * Implemented the UMODE command to the server.
1559 * The server now sends UNKNOWN_COMMAND error status if client sends
1560 unknown command. Affected file silcd/command.c.
1562 * All server commands now handle the command identifier the right
1563 way when sending the command reply to the client. The client can
1564 use to identify the command replies with the identifier.
1566 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * Added silc_server_get_client_route to resolve the route to
1569 the client indicated by the client ID. Affected file is
1572 * Added silc_server_relay_packet as general function to relay
1573 packet to arbitrary destination. This deprecates functions
1574 like _send_private_message_key, _relay_notify etc. Affected
1575 file is silcd/packet_send.[ch].
1577 Removed silc_server_send_key_agreement,
1578 silc_server_send_private_message_key and
1579 silc_server_packet_relay_notify functions from the file
1580 silcd/packet_send.[ch].
1584 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1585 server. Affected file silcd/packet_receive.[ch].
1587 * Implemented the KILL command to the client. Implemented the
1588 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1589 Affected files lib/silcclient/command[_reply].c and
1590 lib/silcclient/client_notify.c. Implemented the KILL notify
1591 printing in the user inteface.
1593 * Fixed a lot silc_parse_nick memory leaks from the client
1594 library in the file lib/silcclient/command.c.
1596 * Changed the silc_server_send_notify_on_channels's `sender'
1597 argument from SilcSocketConnection to SilcClientEntry to
1598 check the sender as entry and not as connection object and not
1599 to send to the client provided as argument. The affected file
1600 is silcd/packet_send.[ch].
1602 * The notify packets that are destined directly to the client used
1603 to not to be processed by the server. Now changed that and the
1604 server processes all notify packets. After relaying the packet
1605 to the client the notify packet is processed in the server.
1607 * The silc_server_free_client_data now checks whether there is
1608 pending outgoing traffic for the client and purges the data to
1609 the network before removing the client entry.
1611 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1613 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1614 an client is killed from the SILC Network. Updated the protocol
1617 Added new function silc_server_send_notify_killed to the
1618 silcd/packet_send.[ch].
1620 * Added function silc_server_packet_relay_notify to relay notify
1621 packets that are destined directly to a client. In this case
1622 the server does not process the notify packets but merely relays
1623 it to the client. Affected file silcd/packet_send.[ch].
1625 Added also silc_server_packet_process_relay_notify to check
1626 whereto relay the notify. Affected file is
1627 silcd/packet_receive.[ch].
1629 * Implemented the KILL command to the server.
1633 * Added the backup schema desgined last fall to the protocol
1634 specs for everyone to see. The specification is in the
1635 *-spec-xx.txt draft and the packet type definitions for the
1636 backup routers is in *-pp-xx.txt draft. Thusly, added also
1637 new packet type SILC_PACKET_CELL_ROUTERS.
1639 * A big security problem in the implementation discovered. The
1640 signoff of an client did not cause new channel key generation
1641 which it of course should've done. The channel keys must be
1642 always re-generated when client leaves (or signoffs) the channel.
1643 The silc_server_remove_from_channels funtion now handles
1644 the channel key re-generation.
1646 * Added `sender' argument to the silc_server_send_notify_on_channels
1647 to not to send the client provided as argument. Affected file
1648 silcd/packet_send.[ch].
1650 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1652 * Implemented OPER and SILCOPER commands into the server and
1655 * Added silc_auth_verify and silc_auth_verify_data to verify
1656 the authentication directly from the authentication payload.
1657 It supports verifying both passphrase and public key based
1658 authentication. Affected file lib/silccore/silcauth.[ch].
1660 * Added `hash' field to the SilcIDListData structure. It is the
1661 hash negotiated in the SKE protocol. Affected file is
1664 * Slight redesigning of the SilcAuthPayload handling routines.
1665 Do not send SilcPKCS but SilcPublicKey as argument.
1667 * Implemented the public key authentication support to the
1668 serverconfig. The public key is loaded from the provided path
1669 and saved as authentication data to void * pointer. Thus,
1670 changed the unsigned char *auth_data to void *auth_data;
1672 * Fixed SHUTDOWN command to send the reply before the server
1673 is shutdown. :) Affected file silcd/command.c.
1675 * Fixed fatal bug in CONNECT command. The hostname was invalid
1676 memory and server crashed. Affected file silcd/command.c.
1678 * Fixed fatal bug in CLOSE command. The server_entry became
1679 invalid but was referenced later in the command. Affected file
1682 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1684 * Fixed fatal bug in failure packet handling. Server ignored
1685 the failure and thus crashed when it came.
1689 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1691 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1692 that the command may be executed only once in (about) 2 seconds.
1693 The old SILC_CF_LAG flag is same but allows command bursts up
1694 to five before limiting.
1696 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1697 server code. Various commands now includes the CF_LAG_STRICT
1698 flag to disallow any kind of miss-use of the command.
1700 * Fixed the silc_buffer_unformat to not to allocate any data
1701 if the length of the data is zero. It used to allocate the
1702 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1704 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1706 * Changed the format of AdminConnection configuration section
1707 in the server. Added username of the admin to the format.
1708 Affected files silcd/serverconfig.[ch].
1710 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1711 to return admin configuration data by host, username and/or
1714 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Implemented WHOWAS command to the server. Added the functions:
1718 silc_server_command_whowas_parse,
1719 silc_server_command_whowas_send_reply,
1720 silc_server_command_whowas_from_client and
1721 silc_server_command_whowas_from_server
1723 * Added <Client ID> argument to the WHOWAS command reply. Updated
1724 the protocol specs accordingly.
1726 * Implemented WHOWAS command and command_reply to the client
1729 Implemented the WHOWAS printing on the user interface.
1731 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1733 * Added new argument to the WHOWAS command reply, the real name.
1734 It is an optional argument. Updated the protocol specs.
1736 * Added SilcIDCacheDestructor callback that is registered when
1737 the SilcIDCache is allocated. The callback is called when
1738 an cache entry in the ID Cache expires, or is purged from the
1739 cache. Added into lib/silccore/idcache.[ch].
1741 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1742 to destruct the client entries when the cache entry expires.
1743 Other ID Cache's in server and in the client library ignores
1746 * If the ID Cache entry's `expire' field is zero then the entry
1747 never expires. Added boolean `expire' argument to the
1748 silc_idcache_add function in the lib/silccore/idcache.[ch].
1749 If it is TRUE the default expiry value is used.
1751 * Added silc_server_free_client_data_timeout that is registered
1752 when client disconnects. By default for 5 minutes we preserve
1753 the client entry for history - for WHOWAS command.
1755 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1757 * Added support to the server to enforce that commands are not
1758 executed more than once in 2 seconds. If server receives
1759 commands from client more frequently, timeout is registered
1760 to process the commands. Affected file silcd/command.c.
1761 Added new function silc_server_command_process_timeout.
1763 * Changed NICK_NOTIFY handling in client library to check that
1764 if the client's nickname was changed, so there is no need to
1765 resolve anything from the server.
1767 * Removed error printing from the WHOIS and IDENTIFY commands.
1768 If error occurs then it is ignored silently in the client library.
1769 The application, however, may map the received error to
1770 human readable error string. The application currently maps
1771 the NO_SUCH_NICKNAME error to string.
1773 * Made the command status message public to the application. Moved
1774 them from lib/silcclient/command_reply.c to
1775 lib/silcclient/command_reply.h. The application can map the
1776 received command status to the string with the
1777 silc_client_command_status_message function.
1779 * Added check to the server to check that client's ID is same
1780 as the Source ID in the packet the client sent. They must
1783 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1785 * Added dist-bzip hook to the Makefile.am to make bzip2
1786 compressed distributions.
1788 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1790 * Server now enforces the maximum length for the nickname and
1791 the channel as protocol specification dictates. 128 bytes for
1792 nickname and 256 bytes for channel name.
1794 * Moved the WHOIS printing to the application. The client libary
1795 does not print out the WHOIS information anymore, the application
1796 must do it. Renamed silc_client_command_reply_whois_print to
1797 the silc_client_command_reply_whois_save.
1799 The client's idle time is also sent to the application now, and
1800 the idle is shown on screen.
1802 * Added silc_client_command_reply_identify_save to save the
1803 received IDENTIFY entries.
1805 * Do not check for channel private keys in message sending and
1806 reception if the channel does not have the PRIVKEY mode set.
1807 Affected file lib/silclient/client_channel.c.
1809 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1811 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1812 just surfaced after chaning the JOIN procedure.
1814 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1816 * Added silc_client_get_clients_by_list to get client entries
1817 from Client ID list, that is returned for example by JOIN
1818 and USERS command replies. The application should use this
1819 function for example when JOIN command reply is received to
1820 resolve the clients already on the channel (library does not
1821 do that anymore as USERS command reply is not used in the JOIN
1822 procedure anymore). Affected files lib/silcclient/silcapi.h and
1823 lib/silcclient/idlist.c.
1825 * JOIN command reply and USERS command reply returns now SilcBuffer
1826 pointers instead of unsigned char pointers when returning
1827 the client list and mode list.
1829 * Added <Client ID> argument to the JOIN command reply, mainly
1830 for the server to identify for which client the command was
1831 originally sent. Updated protocol specs accordingly.
1833 * Added SilcDlist private_key pointer to the SilcChannelEntry
1834 in the client to support the channel private keys. Affected
1835 file is lib/silcclient/idlist.h.
1837 * Added SilcChannelPrivateKey argument to the function
1838 silc_client_send_channel_message so that application can choose
1839 to use specific private ke if it wants to. If it is not provided,
1840 the normal channel key is used, unless private keys are set.
1841 In this case the first (key that was added first) is used
1842 as the encryption key.
1844 * Implemented the support for channel private key handling.
1845 Implemented the following functions:
1847 silc_client_add_channel_private_key,
1848 silc_client_del_channel_private_keys,
1849 silc_client_del_channel_private_key,
1850 silc_client_list_channel_private_keys and
1851 silc_client_free_channel_private_keys
1853 Affected file lib/silcclient/client_channel.c.
1855 * Added the support for the private keys in the channel message
1856 sending and encryption and in the message reception and
1857 decryption. Affected funtions are
1858 silc_client_send_channel_message and silc_client_channel_message.
1860 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1862 * Added SKE's key verify callback to the client library's
1863 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1865 * Removed the statement that server (or router) must send USERS
1866 command reply when joining to the channel so that the client
1867 knows who are on the channel. Instead, the client list and
1868 client's mode list is now sent in the JOIN command reply to the
1869 client who joined channel. This is better solution.
1871 * Added function silc_server_get_users_on_channel and function
1872 silc_server_save_users_on_channel to the silcd/server.[ch].
1874 * Removed function silc_server_command_send_users from the
1877 * Do not show topic on the client library anymore. The topic is
1878 sent in the command reply notify to the application and the
1879 application must show the topic now.
1881 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1883 * Added client searching by nickname hash into the IDENTIFY and
1884 WHOIS commands in the server as they were clearly missing from
1885 them. Affected file is silcd/command.c.
1887 * Fixed a bug in private message receiving in the client library.
1888 The remote ID was freed and it wasn't supposed, now it is
1891 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1893 * Minor fix to the channel payload; allocate the data area, as it
1894 needs to be of specific length.
1896 * If the key agreement port is zero then the operating
1897 system will define the bound port. Affected files are
1898 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1900 * Added new function silc_channel_payload_decrypt into the file
1901 lib/silccore/silcchannel.[ch].
1903 * Moved the channel message etc, check from silc_packet_decrypt
1904 to applications. The library calls now a generic
1905 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1906 when the packet is either normal or special. This was done to
1907 allow more wide range of checking that was not allowed when
1908 the code was in library. Now applications can do virtually any
1909 checks to the packet and return to the library the decision how
1910 the packet should be processed. Affected files are
1911 lib/silccore/silcpacket.[ch].
1913 Added silc_server_packet_decrypt_check to the server and
1914 silc_client_packet_decrypt_check to the client library.
1916 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1917 to send with specified source and destination information.
1919 * Channel message delivery between routers was broken after the
1920 channel key distribution was fixed earlier. The channel key
1921 was used be to distributed to other routers as well which is not
1922 allowed by the protocol. Now this is fixed and channel keys
1923 really are cell specific and the channel message delivery between
1924 routers comply with the protocol specification.
1926 * Fixed various commands in server to check also the global list
1927 for the channel entry and not just the local list. The affected
1928 file silcd/command.c.
1930 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1932 * Added assert()s to buffer formatting and unformatting routines
1933 to assert (if --enable-debug) when error occurs. Affected
1934 file: lib/silcutil/silcbuffmt.c.
1936 * Changed to auto-reconnect to check whether the remote host is
1937 router and register the re-connect timeout if it is. It used
1938 to check that whether we are normal server, but router must do
1939 auto-reconnect with another router as well. Affected file
1942 * Removed the [<key len>] option from CMODE command as the cipher
1943 name decides the key length, nowadays. See the defined ciphers
1944 from the protocol specification.
1946 * Added [<hmac>] option to the CMODE command to define the HMAC
1947 for the channel. Added SILC_CMODE_HMAC channel mode.
1949 * Added [<hmac>] option for the JOIN command so that user can
1950 select which HMAC is used to compute the MACs of the channel
1953 * Added Hmac field to the Channel Message Payload. The integrity
1954 of plaintext channel messages are now protected by computing
1955 MAC of the message and attaching the MAC to the payload. The
1956 MAC is encrypted. Now, it is clear that this causes some
1957 overhead to the size of the packet but rationale for this is that
1958 now the receiver can verify whether the channel message decrypted
1959 correctly and also when private keys are set for the channel the
1960 receiver can decrypt the packet with several keys and check from
1961 the MAC which key decrypted the message correctly.
1963 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1964 lib/silccrypt/silccipher.[ch].
1966 * Added silc_hash_len to return the digest length into the
1967 lib/silcrypt/silchash.[ch].
1969 * Rewrote parts of Silc Channel Payload interface in the
1970 lib/silccore/silcchannel.[ch]. The encode function now also
1971 encrypts the packet and parse function decrypts it.
1973 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1975 * Fixed a minor formatting bug in the SKE's key material processing.
1976 It actually might have processed the keys wrong way resulting
1979 * Redefined the mandatory HMAC algorithms and added new algorithms.
1980 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1981 and hmac-md5 truncated to 96 bits. The mandatory is now
1982 hmac-sha1-96. Rest are optional (including the one that used
1983 to be mandatory). Rationale for this is that the truncated HMAC
1984 length is sufficient from security point of view and can actually
1985 make the attack against the HMAC harder. Also, the truncated
1986 HMAC causes less overhead to the packets. See the RFC2104 for
1989 * Added new [hmac] configuration section. The SKE used to use
1990 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1991 is of course wrong. The official names that must be proposed in
1992 the SKE are the ones defined in the protocol specification
1993 (hmac-sha1-96 for example). The user can configure any hmac
1994 using any hash function configured in the [hash] section. At
1995 least, the mandatory must be configured.
1997 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1999 * Added HMAC list to the SKE proposal list. It has now both
2000 hash algorithm list and HMAC list. This makes the protocol
2001 incompatible with previous versions. The SKE now seems to work
2002 the way it is supposed to work, for the first time actually.
2004 * Defined plain Hash algorithms to the protocol specification.
2007 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2009 * Implemented support for key agreement packets into the server.
2010 Added functions silc_server_key_agreement and
2011 silc_server_send_key_agreement. Other than these functions,
2012 server has nothing to do with this packet.
2014 * Added support for private message key packets into the server.
2015 Added functions silc_server_private_message_key and
2016 silc_server_send_private_message_key.
2020 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2021 called in the protocol's final callback instead in the END
2022 protocol state. This makes a little more sense and in the same
2023 time in client we can use the same protocol routines for normal
2024 key exchange and to key agreement packet handling as well.
2026 * Added to both client's and server's KE protocol context the
2027 SilcSKEKeyMaterial pointer to save the key material. We will
2028 bring the key material to the protocol's final callback by doing
2029 this. The final callback must free the key material.
2031 * Added SKE's packet_send callback into client's KE protocol
2032 context so that the caller can choose what packet sending function
2033 is used. This way we can use different packet sending when
2034 doing normal SKE when doing key agreement packet handling (in
2035 the key agreement packet handling we do not want to encrypt
2038 * Implemented the responder side of the key agreement routines
2039 in the client. The client can now bind to specified port and
2040 accept incoming key negotiation. The key material is passed
2041 to the application after the protocol is over.
2043 * Implemented the processing of incoming Key Agreement packet
2044 in the client. Added function silc_client_key_agreement to
2047 * Implemented the intiator side of the key agreement routines
2048 in the client. The client can now initiate key agreement with
2049 another remote client. The key material is passed to the
2050 application after the protocol is over.
2052 * Created client_keyagr.c to include all the key agreement
2055 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2056 SILC_TASK_CALLBACK except that it is not static.
2058 * Created client_notify.c and moved the Notify packet handling
2059 from the client.[ch] into that file.
2061 * Created client_prvmsg.c and moved all private message and
2062 private message key routines from the client.[ch] into that file.
2064 * Create client_channel.c and moved all channel message and
2065 channel private key routines from the client.[ch] into that file.
2067 * Changed silc_client_get_client_by_id_resolve to resolve with
2068 WHOIS command instead of IDENTIFY command, in the file
2069 lib/silclient/idlist.c.
2071 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2073 * Implemented the SKE's responder side to the Client library.
2075 * When FAILURE is received to the protocol do not trust it
2076 blindly. Register a timeout to wait whether the remote closes
2077 the connection as it should do it, only after that process the
2078 actual failure. This was changed to both client and server.
2080 * Added client_internal.h to include some of the structures
2081 there instead of client.h in lib/silcclient/.
2083 * Added function silc_task_unregister_by_callback to unregister
2084 timeouts by the callback function.
2086 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2088 * Some "Incomplete WHOIS info" errors has been appearing on the
2089 log files. Took away the entry->userinfo check from WHOIS
2090 reply sending. The entry->userinfo is now " " if client did not
2091 provide one. I thought this was fixed earlier but something
2092 is wrong still. Let's see if the error still appears.
2094 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2096 * Fixed a minor bug in the login when the channel key is
2097 re-generated in the server. It used to generate the key in
2098 wrong order and thus caused problems in the channel traffic.
2100 * Fixed a minor bug in channel key distsribution after
2101 KICK command. The key was not sent to the router even though
2104 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2106 * Added silc_ske_process_key_material_data as generic routine
2107 to process any key material as the SILC protocol dictates. The
2108 function is used by the actual SKE library but can be used by
2109 applications as well. This relates to the private message keys
2110 and the channel private keys since they must be processed the
2111 same way the normal SILC session keys. The protocol dictates
2112 this. Affected files: lib/silcske/silcske.[ch].
2114 Added also silc_ske_free_key_material to free the
2115 SilcSKEKeyMaterial structure.
2117 * Defined silc_cipher_set_key function to set the key for
2118 cipher without using the object's method function. The affected
2119 files: lib/silccrypt/silccipher.[ch].
2121 * Implemented silc silc_client_add_private_message_key,
2122 silc_client_add_private_message_key_ske,
2123 silc_client_del_private_message_key,
2124 silc_client_list_private_message_keys and
2125 silc_client_free_private_message_keys functions in the
2128 Added functions silc_client_send_private_message_key to send
2129 the Private Message Key payload and silc_client_private_message_key
2130 to handle incoming Private Message Key payload.
2132 * Added Cipher field to the Private Message Key payload to set
2133 the cipher to be used. If ignored, the default cipher defined
2134 in the SILC protocol (aes-256-cbc) is used.
2136 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2138 * Removed lib/silcclient/ops.h file.
2140 Redefined parts of the SILC Client Library API. Created new
2141 file silcapi.h that deprecates the ops.h file and defines the
2142 published Client Library API. Defined also private message key
2143 API and channel private key API into the file.
2145 This is the file that the application must include from the
2146 SILC Client Library. Other files need not be included by
2147 the application anymore.
2149 * Added new key_agreement client operation callback and also
2150 defined the Key Agreement library API for the application.
2152 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2154 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2155 is used by clients to request key negotiation between another
2156 client in the SILC network. If the negotiation is started it
2157 is performed using the SKE protocol. The result of the
2158 negotiation, the secret key material, can be used for example
2159 as private message key.
2161 Implemented the Key Agreement payload into the files
2162 lib/silccore/silauth.[ch].
2164 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2166 * Redefined ciphers for the SILC protocol. Added some new ciphers
2167 and defined the key lengths for the algorithms. Changed the
2168 code accordingly. The default key length is now 256 bits.
2170 * Fixed SKE key distribution function silc_ske_process_key_material
2171 when the key length is more than 128 bits. The default key
2172 length in SILC is now 256 bits.
2174 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2175 to indicate unsupported algorithm.
2177 * Renamed rijndael.c to aes.c and all functions as well.
2179 * Fixed a long standing channel key setting bug in client library.
2180 Weird that it has never surfaced before.
2182 * Fixed bug in channel deletion. If the entire channel is removed
2183 then it must also delete the references of the channel entry
2184 from the client's channel list as the client's channel entry and
2185 the channel's client entry share same memory.
2187 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2189 * Implemented CONNECT and SHUTDOWN commands in the client.
2191 * Implemented CLOSE command to the client.
2193 * Added the function silc_idlist_find_server_by_name into the
2194 files silcd/idlist.[ch].
2196 Added the function silc_idlist_find_server_by_conn into the
2197 files silcd/idlist.[ch].
2199 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2201 * DIE command was renamed to SHUTDOWN. Updated the both code
2204 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2205 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2207 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2210 * Added function silc_server_create_connection function to create
2211 connection to remote router. My server implementation actually
2212 does not allow router to connect to normal server (it expects
2213 that normal server always initiates the connection to the router)
2214 so the CONNECT command is only good for connecting to another
2217 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2219 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2220 or some other client was kicked from the channel.
2222 Implemented the handling of the notify type to both client
2225 Implemented silc_server_send_notify_kicked to send the KICKED
2226 notify. It is used to send it to the server's primary router.
2228 * Implemented the KICK command into server and client.
2230 * Added `query' argument to the silc_idlist_get_client function
2231 to indicate whether to query the client from server or not if
2234 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2235 to indicate that the client is not channel founder.
2239 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2241 * Removed the rng context from SilcPacketContext structure and
2242 changed that the packet routine uses the Global RNG API.
2244 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2246 * Added support for quit message that client can "leave" on the
2247 channel when it quits the SILC. It is ditributed inside the
2248 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2250 Added silc_server_free_client_data that will take the
2251 signoff message as argument.
2253 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2255 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2257 * Updated parts of the protocol specification to keep it up
2260 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2262 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2263 payloads in one packet.
2265 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2266 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2267 use now the new List flag.
2269 * Also deprecated the following packet types: REPLACE_ID,
2270 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2272 * Added list support for Notify packet in server.
2274 * Added silc_server_send_notify_channel_change to send the
2275 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2276 the silc_server_send_replace_id.
2278 * Added silc_server_send_notify_nick_change to send the
2279 NICK_CHANGE notify type. Deprecates the function
2280 silc_server_send_replace_id.
2282 * Added silc_server_send_notify_join to send the JOIN notify type.
2283 Deprecates the function silc_server_send_new_channel_user.
2285 * Added silc_server_send_notify_leave to send LEAVE notify type.
2286 Deprecates the function silc_server_send_remove_channel_user.
2288 * Added silc_server_send_notify_cmode and
2289 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2290 types. Deprecates the silc_server_send_set_mode function.
2292 * Added SERVER_SIGNOFF notify type to indicate that server has
2293 quit. This means that all clients on the channel from that
2294 server will drop. This can be also used when netsplit happens.
2296 Deprecated REMOVE_ID packet type since it is not needed anymore
2299 Added silc_server_send_notify_server_signoff to send the
2300 SERVER_SIGNOFF notify type. Deprecates the function
2301 silc_server_send_remove_id.
2303 Added also silc_server_send_notify_signoff to send the
2304 SIGNOFF notify type.
2306 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2307 SILC protocol from this day on. Changed the protocol
2308 specification as well.
2310 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2311 notify type. It is used between routers to notify about
2312 topic changes on a channel.
2314 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2317 * Partly updated the protocol specification to comply with the
2318 changes now made. It is still though a bit outdated.
2320 * The JOIN notify type now takes one extra argument <Channel ID>.
2321 The packet used to be destined to the channel but now the
2322 JOIN type may be sent as list thus it is impossible to
2323 destine it to any specific channel. By adding this argument
2324 it is again possible.
2326 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2328 * Added CREDITS file. The CHANGES and CREDITS file will appear
2329 in the distribution as well.
2331 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2334 types in the server's silcd/packet_receive.c.
2336 * Implemented CMODE and CUMODE to work in router environment.
2338 * Fixed minor encoding and decoding buglet from the
2339 lib/silccore/silcmode.c.
2341 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2344 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2346 * Changed all SilcConfigServer* and silc_config_server* to
2347 SilcServerConfig* and silc_server_config*, respectively.
2350 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Associated the ID (client or server ID) to the Authentication
2353 Payload to avoid any possibility of forging. Updated the
2354 protocol specification and the code accordingly.
2356 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2358 * The RSA key length is now save to the RsaKey context in the
2359 key generation process in lib/silccrypt/rsa.c. The key length
2360 is now used to figure out the maximum size of the block allowed
2361 to be encrypted/signed.
2363 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2364 is equivalent to the silc_mp_mp2bin but does not allocate any
2367 * Changed silc_mp_mp2bin API to take length argument. If it is
2368 non-zero then the buffer is allocated that large. If zero, then
2369 the size is approximated using silc_mp_sizeinbase, which however
2372 * Created Global RNG API which is global RNG that application can
2373 initialize. After initializing, any routine anywhere in the
2374 code (including library) can use RNG without allocating a new
2375 RNG object. This was done to allow this sort of use of the
2376 RNG in code that has no chance to allocate RNG object. All
2377 applications currently allocate this and many routines in the
2378 library use this. Affected file lib/silccrypt/silcrng.[ch].
2380 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2381 it to use the Global RNG API.
2383 * Defined Authentication Payload into protocol specification that
2384 is used during SILC session to authenticate entities. It is
2385 used for example by client to authenticate itself to the server
2386 to obtain server operator privileges.
2388 Implemented this payload into the lib/silccore/silcauth.[ch].
2389 Implemented also routines for public key based authentication
2390 as the new protocol specification dictates.
2392 Moved definitions of different authentication methods from
2393 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2395 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2396 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2397 silc_pkcs_verify_with_hash functions into the file
2398 lib/silccrypt/silcpkcs.[ch].
2400 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2402 * The client entry's userinfo pointer must be always valid.
2403 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2404 will fail since it requires the userinfo. Now, the userinfo
2405 is allocated as "" if actual userinfo does not exist. Actually,
2406 it must exist and it is totally Ok to drop client connections
2407 that does not announce the userinfo. However, we will make
2408 this workaround for now.
2410 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2411 to return the remote port by socket.
2413 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2416 SILC_SERVER_PENDING_EXEC and added an new macro
2417 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2418 data or when error occurs while processing the pending command.
2420 Added new argument `destructor' into silc_server_command_pending
2421 and to the SilcServerCommandPending object. This destructor is
2422 now called after calling the pending callback or if error occurs
2423 immediately. If error occurs the actual pending callback won't
2424 be called at all - only the destructor. The destructor may be
2425 NULL if destructor is not needed.
2427 All this applies for client library code as well. Similar
2428 changes were made there as well for the pending commands.
2430 In the client, the application must now allocate the
2431 SilcClientCommandContext with the silc_client_command_alloc
2434 * Added reference counter to the SilcServerCommandContext. Added
2435 function silc_server_command_alloc and silc_server_command_dup
2438 Same type of functions added to the client library for the same
2441 * Removed the cmd_ident from IDListData away since it is now
2442 global for all connections. It is the command identifier used
2443 in command sending and with pending commands. The affected file
2446 * Added reference counter to the SilcSocketConnection objecet to
2447 indicate the usage count of the object. The object won't be
2448 freed untill the reference counter hits zero. Currently only
2449 server uses this, and client ignores it. The client must be
2450 set to use this too later. The affected files are
2451 lib/silccore/silcsockconn.[ch]. Added also the function
2452 silc_socket_dup to increase the reference counter.
2454 This was mainly added because it is possible that the socket
2455 is removed underneath of pending command or other async
2456 operation. Now it won't be free'd and proper DISCONNECTING
2457 flags, etc. can be set to avoid sending data to connection that
2458 is not valid anymore.
2460 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2461 the connection. After that it sets SILC_SET_DISCONNECTED.
2462 It is, however, possible that the socket data is not still freed.
2463 The silc_server_packet_process now checks that data is not
2464 read or written to connection that is DISCONNECTED. The socket
2465 get's freed when the reference counter hits zero.
2467 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * Changed the client operation API: channel_message operation's
2470 `sender' is now the client entry of the sender, not the nickname
2471 and the `channel' is the channel entry, not the channel name.
2473 In the private_message operation the `sender' is now also the
2474 client entry of the sender not the nickname.
2476 Affected file is lib/silcclient/ops.h and all applications
2477 using the client operations.
2479 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2481 * Moved the calling of ops->connect() from connect_to_server_final
2482 into receive_new_id functin since that is the point when the
2483 client is actually allowed to send traffic to network. The
2484 affected file is lib/silcclient/client.c.
2486 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2488 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2489 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2490 (if needs broadcasting) instead of broadcasting the packets one
2491 by one which would make a burst in the network traffic.
2493 * Added `broadcast' argument to the functions in silcd/server.[ch]
2494 silc_server_create_new_channel[_with_id] to indicate whether
2495 to send New Channel packet to primary router.
2497 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2499 * Added new function into the silcd/server.[ch] files:
2500 silc_server_create_new_channel_with_id to create new channel with
2501 already existing Channel ID.
2503 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2504 lib/silccore/silcpacket.h. This packet is used t send list of
2505 Set Mode payloads inside one packet. Server uses this to set
2506 the modes for the channels and clients on those channels, that it
2507 announced to the router when it connected to it. The protocol
2508 specification has been updated accordingly.
2510 * The silc_server_new_channel did not handle the packet coming
2511 from normal server as it normally does not send that. However,
2512 when it announces its channels it does send it. Implemented
2513 the support for that.
2515 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2516 into the file lib/silccore/id.h.
2518 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2520 * Fixed memory leaks in the functions silc_idlist_del_client,
2521 silc_idlist_del_channel and silc_idlist_del_server in the file
2522 silcd/idlist.c. All of those leaked like a sieve.
2524 * Fixed some small memory leaks in the client's function
2525 silc_client_notify_by_server.
2527 * Added functions into silcd/server.c: silc_server_announce_clients,
2528 silc_server_announce_channels and silc_server_announce_server.
2529 These functions are used by normal and router server to announce
2530 to its primary router about clients, channels and servers (when
2531 router) that we own. This is done after we've connected to the
2534 These functions effectively implements the following packet types:
2535 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2536 and SILC_PACKET_NEW_ID_LIST.
2538 * Added new functions into the silcd/packet_receive.[ch]:
2539 silc_server_new_id_list, silc_server_new_channel_list and
2540 silc_server_new_channel_user_list to handle the incoming
2541 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2543 * Added support of changing Channel ID in the function
2544 silc_server_replace_id. If the server that announces a channel
2545 to the router already exists in the router (with same name but
2546 with different Channel ID), router is responsible to send
2547 Replace ID packet to the server and force the server to change
2548 the Channel ID to the one router has.
2550 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2551 client that the Channel ID has been changed by the router. The
2552 normal server sends this to the client. Client must start using
2553 the new Channel ID as the channel's ID.
2555 Implemented handling of this new type into lib/silcclient/client.c
2556 into the function silc_client_notify_by_server.
2558 * Added new function silc_idlist_replace_channel_id into the files
2559 silcd/idlist.[ch] to replace the Channel ID.
2561 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2563 * Call silc_server_command_identify_check always when processing
2564 the IDENTIFY command in silcd/command.c
2566 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2568 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2569 send keepalive packets. The packet can be sent by clients,
2570 servers and routers.
2572 Added function silc_socket_set_heartbeat into the file
2573 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2574 If not set, the heartbeat is not performed. The actual
2575 heartbeat is implemented in the low level socket connection
2576 library. However, application is responsible of actually
2579 Added silc_server_send_heartbeat to send the actual heartbeat
2580 packet into silcd/packet_send.[ch]. Server now performs
2581 keepalive with all connections.
2583 * Added silc_task_get_first function into lib/silcutil/silctask.c
2584 to return the timeout task with shortest timeout. There was a bug
2585 in task unregistration that caused problems. TODO has been
2586 updated to include that task system must be rewritten.
2588 * The client library will now resolve the client information when
2589 receiving JOIN notify from server for client that we know but
2590 have incomplete information.
2592 * Rewrote parts of silc_server_remove_from_channels and
2593 silc_server_remove_from_one_channel as they did not remove the
2594 channel in some circumstances even though they should've.
2596 * Encryption problem encountered in server:
2598 The LEAVE command used to send the Channel Key packet to the
2599 router immediately after generating it. However, the code
2600 had earlier sent Remove Channel user packet but not immediately,
2601 ie. it was put to queue. The order of packets in the router
2602 was that Channel Key packet was first and Remove Channel User
2603 packet was second, even though they were encrypted in the
2604 reverse order. For this reason, MAC check failed. Now, this
2605 is fixed by not sending the Channel Key packet immediately but
2606 putting it to queue. However, this is more fundamental problem:
2607 packets that are in queue should actually not be encrypted
2608 because packets that are sent immediately gets encrypted
2609 actually with wrong IV (and thus MAC check fails). So, packets
2610 that are in queue should be encrypted when they are sent to
2611 the wire and not when they put to the queue.
2613 However, the problem is that the current system has not been
2614 designed to work that way. Instead, the packet is encrypted
2615 as soon as possible and left to the queue. The queue is then
2616 just purged into wire. There won't be any fixes for this
2617 any time soon. So, the current semantic for packet sending
2620 o If you send packet to remote host and do not force the send
2621 (the packet will be in queue) then all subsequent packets to the
2622 same remote host must also be put to the queue. Only after the
2623 queue has been purged is it safe again to force the packet
2626 o If you send all packets immediately then it safe to send
2627 any of subsequent packets through the queue, however, after
2628 the first packet is put to queue then any subsequent packets
2629 must also be put to the queue.
2631 Follow these rules and everything works fine.
2633 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2635 * Added new function silc_server_remove_clients_by_server to
2636 remove all client entries from ID list when the server connection
2637 is lost. In this case it is also important to invalidate all
2638 client entires as they hold the invalid server entry. This
2639 fixes fatal bug when server has lost connection and will reconnect
2642 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Made some sanity checks to silc_server_daemonise like to check
2645 whether the requested user and group actually exists.
2647 * Added sanity check to SKE's silc_ske_responder_finish to check
2648 that the public and private key actually is valid.
2650 * Invalidate the client's nickname when receiving Replace ID
2651 packet and the Client ID is being replaced. This means that the
2652 server will query the nickname if someone needs it (client)
2655 * Sort the ID Cache in client library when the ID Cache data
2656 has changed (needs sorting).
2658 * Do not allow for SILC client to create several connections to
2659 several servers. The client does not support windows right now
2660 and generating multiple connections causes weird behaviour.
2662 Irssi-silc client does support windows and can handle several
2663 connections without problems, see: www.irssi.org and SILC plugin.
2665 * Fixed some places where client was added to the IDList. The
2666 rule of thumb is following (in order to get everything right):
2667 If the client is directly connected local client then the
2668 `connection' argument must be set and `router' argument must be
2669 NULL to silc_idlist_add_client function. If the client is not
2670 directly connected client then the `router' argument must
2671 bet set and the `connection' argument must be NULL to the
2672 silc_idlist_add_client function.
2674 * The funtion silc_server_packet_send_local_channel actually did
2675 not check whether the client was locally connected or not. It
2676 does that now. Fixed a bug related to LEAVE command.
2678 * Fixed Remove Channel User payload parsing bug in server's
2679 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2681 * The server's silc_server_save_channel_key now checks also the
2682 global ID list for the channel as it might not be in the local
2683 list. Fixed a bug related to LEAVE command.
2685 * Is this the end of the [<unknown>] buglet that has been lurking
2686 around for a long time? A little for loop fix in server's
2687 silc_server_command_whois_parse that is used by both IDENTIFY
2688 and WHOIS command. At least, this was a clear bug and a cause
2689 of one type of [<unknown>] buglet.
2691 * WHOIS and IDENTIFY commands call the function
2692 silc_server_command_[whois/identify]_check function even if
2693 we are not router server.
2695 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * Added --with-gmp configuration option. If set the GMP
2698 is always compiled in the SILC source tree. If not set then
2699 it is checked whether the system has the GMP3 installed. If
2700 it has then the GMP won't be compiled (the system's headers
2701 and library is used), if it doesn't have it then the GMP is
2702 compiled in the SILC source tree.
2704 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2706 * Changed RSA private exponent generation to what PKCS #1
2707 suggests. We try to find the smallest possible d by doing
2708 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2709 not security fix but optimization.
2711 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2713 * Added new config entry [Identity] to fork the server and run
2714 it as specific user and group. A patch from Bostik.
2716 * Imported Dotconf configuration library into lib/dotconf.
2717 This will be used to create the SILC configuration files later.
2718 It will appear in the distsribution after this commit.
2720 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2722 * A big code auditing weekend happening. Auditing code for
2723 obvious mistakes, bugs and errors. Also, removing any code
2726 Removed files for being obsolete:
2728 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2729 inline in the file lib/silcutil/silcbuffer.h)
2731 o lib/silcutil/silcbufutil.c (the header has inline versions)
2733 Changed code to fix possible error conditions:
2735 o The buffer formatting routines now check that the destination
2736 buffer really has enough space to add the data. This applies for
2737 both buffer formatting and unformatting
2738 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2739 unformatting was changed to accomodate following rules:
2740 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2741 sent to the function while XXX_*STRING will not allocate or copy
2742 the data into the buffer. Instead it sets the pointer from the
2743 buffer into the pointer sent as argument (XXX_*STRING used to
2744 require that the pointer must be allocated already). This change
2745 makes this whole thing a bit more consistent and more optimized
2746 (note that the data returned in the unformatting with XXX_*STRING
2747 must not be freed now). The routines return now -1 on error.
2749 o Tried to find all code that use buffer_format and buffer_unformat
2750 and added return value checking to prevent formatting and
2751 especially unformatting errors and possible subsequent fatal
2754 o Changed ske->x and ske->KEY to mallocated pointers in
2755 lib/silcske/silcske.h. Fixed possible data and memory leak.
2757 o Added return value checking to all *_parse* functions. Fixed
2758 many memory leaks as well.
2760 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2761 so that buffer overflows would not happen. All code now also
2762 checks the return value as it can fail.
2764 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Added reconnection support to server if the normal server looses
2767 its connection to the router (for example if router is rebooted).
2768 The server performs normal reconnection strategy implemented
2769 to the server. Affected file silcd/server.c.
2771 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2773 * Added new packet type SILC_PACKET_SET_MODE that is used to
2774 distribute the information about changed modes (for clients,
2775 channels and clients channel modes) to all routers in the
2776 network. Updated the protocol specification accordingly.
2778 Added functions into silcd/packet_send.c and
2779 silcd/packet_receive.c: silc_server_send_set_mode,
2780 silc_server_set_mode.
2782 Added new files silcmode.[ch] into lib/silccore that implements
2783 the encoding and decoding of Set Mode Payload. Added new type
2784 SilcSetModePayload. Moved the definitions of different modes
2785 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2787 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Oops, a little mistake in server's connection authentication
2790 protocol. The protocol is not ended with FAILURE but with
2791 SUCCESS if the authentication is Ok. :) Affected file is
2794 * Implemented NICK_CHANGE notify handling in server in the file
2795 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2796 the local clients on the channel. After the changing nickname
2797 in router environment snhould work and the [<unknown>] nickname
2798 should appear no more.
2800 The silc_server_replace_id function that receives the Replace ID
2801 payload now sends the NICK_CHANGE notify type also in the file
2802 silcd/packet_receive.c
2804 * Changed WHOIS and IDENTIFY command to support the maximum amount
2805 of arguments defined in protocol specs (3328 arguments). This
2806 fixed a bug that caused problems when there were more than three
2809 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Added extra parameter, command identifier, to the
2812 silc_client_send_command so that explicit command identifier
2815 Changed that ID list routines uses specific command identifier
2816 when sending WHOIS/IDENTIFY requests to the server so that they
2817 can be identified when the reply comes back.
2819 Affected files lib/silcclient/command.[ch],
2820 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2822 * Added `sender' argument to silc_server_packet_send_to_channel
2823 to indicaet the sender who originally sent the packet to us
2824 that we are now re-sending. Ignored if NULL. Affected file
2825 silcd/packet_send.[ch].
2827 * Added some server statistics support in silcd/server_internal.h
2828 SilcServerStatistics structure and around the server code. Also
2829 send some nice statistics information when client is connecting
2832 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2834 * Fixed channel ID decoding in server's JOIN command reply in
2835 silcd/command_reply.c
2837 * Fixed braodcasting of replace ID payload to not to send it if
2838 we are standalone server in silcd/packet_receive.c.
2840 * Fixed all channel message sending routines to not to send
2841 packets to clients that has router set, since they are routed
2842 separately in the same function earlier. Affects file
2843 silcd/packet_send.c and all channel packet sending functions.
2845 * In USERS reply, res_argv[i] are not allocated, the table
2846 is allocated. Thus changed that free the table, not its
2849 * In server's whois_check and identify_check if the client is
2850 locally connected do not send any WHOIS commands - they are not
2853 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Fixed some minor bugs in client when sending WHOIS command. The
2856 arguments was in wrong order.
2858 * Removed statis function add_to_channel from server in
2859 silcd/command.c that was previously used with the joining but
2862 * Tested USERS command in router environment successfully with two
2863 routers, two servers and two clients.
2865 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Reorganized the USERS command and command reply in client library
2868 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2869 When the command is given by user we register a pending command
2870 callback that will reprocess the command after the reply has been
2871 received from the server. When reprocessing the packet we then
2872 display the information. Thus, the USERS information is displayed
2873 now in the command callback instead of in the command reply
2874 callback. The processing of the command is same as previously
2875 when server has sent the command reply in the JOINing process.
2877 * Added to USERS command in silcd/command_reply.c to join the client,
2878 we didn't use to know about, to the channel after we've created
2879 a client entry for it. Also, for clienet we did know already still
2880 check whether it is on the channel or not and add it if not.
2882 * Removed silc_server_command_join_notify as the function and its
2885 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2887 * Changed the client's pending command handling to the same as the
2888 server's pending command handling. It is also now possible to
2889 execute command reply functions from other command reply
2890 function as the function callbacks for commands and command
2891 replies are one and same. The pending commands are not static
2892 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2893 in client connection context. Thus, pending commands are server
2894 connection specific as it is convenient.
2896 Changed the function silc_client_command_pending and
2897 silc_client_command_pending_del and added new function
2898 silc_client_command_pending_check. Removed the
2899 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2902 * Added cmd_ident, current command identifier, to the client
2903 connection context in lib/silcclient/client.h to keep track on
2904 command identifiers used in command sending. Client's command reply
2905 function handling now supports the mandatory command identifiers.
2907 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2908 funtions in client to fully support pending command callbacks.
2910 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2911 as one of the arguments to the application in the command reply
2914 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2915 before first releasing SILC but came back. Now it is removed again
2916 and should come back nomore. The FORWARDED flag was used only
2917 by the JOINing procedure by forwarding the command packet to router.
2918 Now, the JOINing procedure has been changed to more generic (due
2919 to various router environment issues) and FORWARDED is not needed
2920 anymore for anything. The protocol specification is yet to be
2923 Now, removed silc_server_packet_forward from server and the flag
2924 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2926 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * Renamed NAMES command to USERS command. The NAMES was named that
2929 due to historical reasons. Now it is renamed. Also, rewrote
2930 parts of the USERS command. The nickname list is not sent anymore
2931 by the server. Only Client ID and mode lists are sent in the USERS
2932 command. Changed this also to the protocol specification.
2934 The client now resolves the names and stuff after it receives
2935 the USERS list from the server when joining to the channel.
2937 * WHOIS and IDENTIFY commands has been changed to support multiple
2938 Client ID's per command. One can now search for multiple users
2939 in the network by sending only one WHOIS or IDENTIFY command.
2940 Changed the code and the protocol specifications.
2942 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2943 uses silc_server_command_whois_parse to parse the request. */
2945 * If normal server, do not parse the WHOIS and IDENTIFY requests
2946 before sending it to the router. Saves some time.
2948 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2950 * Fixed JOIN command on client library. Wrong number of arguments
2951 used to crash the client.
2953 * Added silc_server_channel_has_global function to check whether
2954 channel has global users or not.
2956 * Added silc_server_channel_has_local function to check whether channel
2957 has locally connected clients on the channel.
2959 * The silc_server_remove_from_one_channel now checks whether the
2960 channel has global users or not after given client was removed from
2961 the channel. It also checks whether the channel has local clients
2962 on the channel anymore. If it does not have then the channel entry
2963 is removed as it is not needed anymore.
2965 * The silc_server_notify now checks on JOIN notify whether the joining
2966 client is one of locally connected or global. If it is global then
2967 the channel has now global users on the channel and that is marked
2968 to the channel entry. Also, it now saves the global client to
2969 global list who is joining and JOINs it to the channel. This is
2970 for normal server, that is.
2972 Changed silc_server_send_notify_on_channel,
2973 silc_server_packet_relay_to_channel and
2974 silc_server_packet_send_to_channel check if we are normal server
2975 and client has router set (ie. global client) do not send the
2976 message to that client, as it is already routed to our router.
2978 * Implemented LEAVE notify type handling in silc_server_notify
2981 * Tested LEAVE command in router environment successfully. Tested
2982 with two routers, two servers and two clients.
2986 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2988 * Implemented SIGNOFF notify type handling in silc_server_notify
2991 * silc_server_remove_id now removes the client entry from all channels
2992 it has joined and thusly sends SIGNOFF notify type.
2994 * Rewrote the NAMES list generation in server by removing two excess
2995 loops. The lists are created now inside one loop.
2997 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * silc_server_remove_channel_user checks now also global list
3000 for channel and client.
3002 * silc_server_new_channel_user checks now both local and global
3003 list for channel and client. Fixed a bug in client id decoding.
3004 Used to decode wrong buffer.
3006 * silc_server_channel_message checks now both local and global
3007 list for channel entry.
3009 * Tested channel joining (hence JOIN) in router environment
3010 successfully. Tested with two routers, two servers and two
3013 * Tested channel message sending in router environment successfully.
3015 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3017 * Added silc_server_save_channel_key into server.[ch] to save the
3018 received channel key in Channel Key payload processing. It is
3019 also used in JOIN command reply handling.
3021 Equivalent function silc_client_save_channel_key added into
3022 client.[ch] into client library.
3024 * Changed JOIN command reply to send information whether the channel
3025 was created or not (is existing already) and the channel key
3026 payload. Changed protocol specs accordingly.
3028 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3029 the request was sent by ID and not by nickname. Crashed on
3032 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3034 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3035 now correctly save the received data.
3037 * silc_server_free_sock_user_data now notifies routers in the
3038 network about entities leaving the network.
3040 At the same time implemented functions silc_server_remove_id
3041 and silc_server_send_remove_id to receive and send REMOVE_ID
3042 packets. The packet is used to notify routers in the network
3043 about leaving entities. The ID removed will become invalid in
3046 * Added function silc_idlist_del_server into server. Removes and
3047 free's server entry from ID list.
3049 * silc_server_private_message function now checks, if we are router,
3050 that the destination ID really is valid ID, naturally.
3052 * In router when NEW_ID packet is received (for new client) the
3053 hash of the Client ID is saved in the ID Cache but the
3054 client->nickname is set to NULL, instead of putting the hash
3057 IDENTIFY command now also checks that client->nickname must be
3058 valid. If it is not if will request the data from the server who
3059 owns the client. Added new function
3060 silc_server_command_identify_check.
3062 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3063 to set the command to already allocated Command Payload.
3065 * Tested private message sending in router environment with two
3066 routers, two servers and two clients. Fixed minor bugs and now
3069 * Fixed segfault from client's NAMES command. Used to crash if
3072 * Forwarded packets must not be routed even if it is not destined
3073 to the receiver. Changed server code comply with this.
3075 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Added `require_reverse_mapping' boolean value to ServerParams
3078 structure. If TRUE (not default) the server will require that
3079 the connecting host has fully qualified domain name.
3081 If the reverse mapping is not required and hostname could not be
3082 found the IP address is used as hostname.
3084 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Implemented version string checking to both client and server.
3087 The check is incomplete currently due to the abnormal version
3088 strings used in development version of SILC.
3090 * Changed all command functions in server to use the new
3093 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3095 * Changed char *data to unsigned char *data in ID Cache system to
3096 support binary data as ID Cache data. Changed code to support
3097 binary data in lib/silccore/idcache.c.
3099 * Renamed silc_server_packet_relay_command_reply to
3100 silc_server_command_reply as it is normal packet receiving
3101 function. Rewrote the function to accept command replys for
3102 servers and not only for clients.
3104 * Mark remote router always as registered server if we are connecting
3105 to it. Otherwise, commands sent by the router to us are ignored.
3107 * All ID List find routines now returns the ID Cache Entry pointer
3108 as well if requested.
3110 * WHOIS command works now in router environment, tested with two
3111 routers, two servers and two clients.
3113 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3114 in router environment (as it is almost equivalent to WHOIS) but
3115 hasn't been tested thoroughly. Added new functions:
3117 silc_server_command_identify_parse
3118 silc_server_command_identify_send_reply
3119 silc_server_command_identify_from_client
3120 silc_server_command_identify_from_server
3122 * Disabled route cache adding because adding two different ID's with
3123 same IP replaces the old cache entry thus giving wrong route.
3124 The entry->router->connection is always the fastest route anyway
3125 so route cache may not be needed. Of course, new routes maybe
3126 established after receiving the ID when the entry->router->connection
3127 might not be anymore the most optimal.
3129 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * Add route cache for received ID for fast routing.
3133 * Added silc_server_packet_route to route received packet on router
3134 that is not destined to us.
3136 * Renamed silc_server_get_route to silc_server_route_get.
3138 * Added id_string and id_string_len fields into SilcServer to
3139 include encoded ServerID for fast comparing without excess
3140 encoding of the ID's.
3142 * Cleaned up WHOIS command on server side. Added following static
3145 silc_server_command_whois_parse
3146 silc_server_command_whois_check
3147 silc_server_command_whois_send_reply
3148 silc_server_command_whois_from_client
3149 silc_server_command_whois_from_server
3151 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3152 arguments in command replies. All command functions should be
3153 updated to use this macro.
3155 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Minor typo fixes on command reply handling on server.
3159 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Added silc_server_command_add_to_channel internal routine to add
3162 the client to the channel after router has created the channel and
3163 sent command reply to the server.
3165 * Added generic silc_server_send_command to send any command from
3168 * Use static buffer with ID rendering instead of duplicating data.
3170 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3172 * Fixed a channel user mode bug when joining to a channel server gave
3173 everybody channel founder rights, oops.
3175 * We mark ourselves as the router of the incoming server connection
3176 if we are router ourselves. This way we can check in some packet
3177 sending functions whether it is locally connected server. For
3178 incoming router connections we put NULL.
3180 * For router sending packets locally means now always sending the
3181 packet cell wide; to local clients and local servers. For normal
3182 server sending packet locally means sending it to only local
3185 * Fixed the JOIN command to really work in router environment. If the
3186 channel is created it is always created by the router. Router is
3187 also responsible of making the initial joining to the channel,
3188 sending JOIN notify to the sending server and distributing
3189 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3190 does not exist server doesn't do anything else but forward the
3191 command to the router which performs everything.
3193 * Added silc_server_send_channel_key function to send the Channel Key
3196 * Added silc_server_create_channel_key to create new channel key. The
3197 channel key is now re-generated everytime someone joins or leaves
3198 a channel, as protocol dictates. Note: channel->key_len is the
3201 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3203 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3204 packet_receive.[ch] to separate packet sending and receiving
3205 routines. The server.[ch] now includes everything else including
3206 actual packet processing (writing and reading data) and other
3209 Renamed silc_server_private_message_send_internal to
3210 silc_server_send_private_message. The routine is still though
3211 used only to relay private messages as server does not send
3212 private messages itself.
3214 Renamed silc_server_new_channel to silc_server_create_new_channel
3215 and added new function sicl_server_new_channel that handles the
3216 incoming New Channel packet. Added also new sending function
3217 silc_server_send_new_channel to send New Channel Payload.
3219 * Added new function silc_server_notify to process incoming notify
3220 packet to the server/router. Server may then relay the notify
3221 to clients if needed.
3223 * Added new function silc_server_new_channel_user to process incoming
3224 New Channel User packet. Router will redistribute the packet and
3225 send JOIN notify to its local clients and locally connected servers
3226 if needed. Normal server will send JOIN notify to its local client
3227 on same channel when received this packet. Added also corresponding
3228 sending function silc_server_send_new_channel_user to sent the
3231 * Added boolean route argument to send_notif_to_channel and
3232 packet_send_to_channel functions to attempt to route the packet
3233 if it is TRUE and send only locally if it is FALSE.
3235 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * silc_server_replace_id now broadcasts the received replace ID
3238 packet if it is not broadcast packet already. The router must
3239 broadcast to inform other routers about changed ID.
3241 * Added backpointer to server's router into SilcServer context in
3242 silcd/server_internal.h.
3244 * Fixed silc_server_packet_broadcast to send correct broadcast
3247 * The channel key is now distributed to the local client as soon
3248 as it is received from the router (in router environment) so that
3249 no other packet may be sent for the channel until client has
3252 * silc_server_remove_channel_user now broadcasts the received
3253 Remove Channel User packet if it is not broadcast packet already.
3254 The router must broadcast to inform other routers about removed
3257 * Added users field into SilcPacketContext that is a reference count
3258 of the context. One can increase the reference count by calling
3259 silc_packet_context_dup which is now changed to just increase the
3260 reference count instead of duplicating the data. The reference
3261 count is decresed by calling silc_packet_context_free that will
3262 free the data after the reference count hits zero.
3264 For now on the packet context and everything allocated into it
3265 (including the raw packet from network) must be freed by calling
3266 the new silc_packet_context_free function. Added also new function
3267 silc_packet_context_alloc that must be used now to allocate the
3268 context. This also means that if a routine is asynchronous from
3269 silc_[client/server]_packet_parse_type the packet context must
3270 be duplicated by calling silc_packet_context_dup. Otherwise it
3271 gets free'd after silc_[client/server]_packet_parse_type returns.
3272 Also, one must remember that if packet is duplicated then its
3273 reference count must be decresed by calling the free function as
3274 many times as it was duplicated.
3276 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3277 from both client and server.
3279 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Made joining to a channel working in router environment.
3283 * Cleaned up JOIN command on server side and create function
3284 silc_server_command_join_channel internal routine to make the
3287 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3289 * Changed silc_command_pending list to SilcDList. Also, added
3290 `ident' field to SilcServerCommandPending structure to identify
3291 the reply and to call correct callback.
3293 Added silc_server_command_pending_check function to replace the
3294 corresnponding macro. The silc_command_pending list is not
3297 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3298 to set identifier to previously allocated Command Payload. It
3299 is used to set identifier for command when resending Command
3302 * Added silc_command_payload_encode_payload to encode Command
3303 Payload buffer from SilcCommandPayload structure.
3305 * Added silc_argument_payload_encode_payload to encode Argument
3306 payload buffer from SilcArgumentPayload structure.
3308 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Changed WHOIS command to support router connection on server side.
3311 The whois request is always sent to router unless the server is
3312 standalone server. After server has received the reply from the
3313 router will it send the reply to the client.
3315 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3316 broadcast received broadcast packet. The function is used only
3317 by router. The broadcast packet is always sent to the router's
3320 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3321 render given ID to printable string, for log files for example.
3323 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Made basic router to router connections working. At least they
3326 can now connect to each other but nothing really works the way
3327 they are supposed - yet.
3329 * Added new initiator token to RouterConnection configuration
3330 file in silcd/serverconfig.[ch]. It is used to tell whether we
3331 are the initiator to the remote router or whether we'll expect
3332 the other end to connect.
3334 * Moved registering of listener task to silc_server_init, hence
3335 the server starts listenning as soon as it is run, even if it
3336 does not have connections to other routers. Let's see how well
3339 * Changed default connection retry timeouts for more suitable in
3342 * Removed cipher and such arguments from silc_idlist_add_client
3343 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3344 Added new function silc_idlist_add_data to add the keys and stuff
3347 * Added SilcIDListData structure and added it to SilcClientEntry
3348 and SilcServerEntry as their first field in the structure. This
3349 way we can explicitly cast the ID entries to the SilcIDListData
3350 structure and get common data for the entries. In past, we had
3351 to first check what type of connection it is and then cast it to
3352 correct ID entry type. Now, we can directly cast the opaque
3353 pointer to the SilcIDListData (no matter what ID entry it actually
3354 is) and get the data needed.
3356 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3359 in some circumstances even if threre were timeout tasks, though not
3360 IO tasks, but tasks anyway. Now fixed.
3362 * Defined SilcServerConnection structure to hold connection specific
3363 stuff about directly connected servers and routers. The definition
3364 is currently in silcd/server_internal.h. I thought about having
3365 a bit more important role fro this struct but for now it is used
3366 only when connecting to other server (or router actually).
3368 * Added connecting retry support in server when connecting to
3369 router(s). The retry feature implement exponential backoff
3370 algorithm. Also, added SilcServerParams structure to hold default
3371 parameters for server. For now, it include these retry settings
3372 and are hard coded. After server is moded to be as Silc Server
3373 Library this structure will be more important.
3375 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3377 * Changed client librarys channel->clients table to SilcList and
3378 changed code accordingly.
3380 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3382 * Changed client's channel table to SilcList and changed code
3383 accordingly. Also changed SilcChannelClientEntry to include back-
3384 pointer to the channel so that client entry can use that structure
3385 as list as well and we have fast cross-reference to the channel.
3386 This change dramatically decreased the complexity of channel
3387 handling with client entry and vice versa (removed one extra
3388 loop when searching for channel entry from many functions).
3390 * Changed server->sim from table to SilcDList and changed code
3393 * NAMES command can now be used from user interface. It will show
3394 the user list on the channel, neatly.
3396 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3397 Code now saves realname of the user if it becomes available.
3399 * Renamed configure.in to configure.in.pre and made ./prepare
3400 script to automatically add correct version string to
3401 configure.in which it creates from configure.in.pre.
3403 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * NAMES command reply now shows users mode with the nickname when
3408 * Moved silc_client_ch[u]mode[_char] functions from
3409 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3410 place sucks, they are utility functions and should be in some
3413 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3415 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3418 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3422 * Added TRQ (efficient deque and list library) into lib/trq. This is
3423 a very good list library that is currently used in the SILC. Defined
3424 SilcList API over the library because I didn't like the API very
3425 much. See lib/trq/silclist.h for the API and examples of how to
3426 use the API. Fixed various places in the code to use the new
3427 SilcList API. The SilcList is meant for lists that has a structure
3428 already defined as a list. It is not suitable to add just some
3429 context to the list (in TRQ, the context is the list actually).
3431 So, I defined SilcDList that can be used for the purpose where
3432 predefined list structure does not exit. This can be used as
3433 such list. Now some context just can be added to the SilcDList.
3434 Currently this list is not used in the SILC just yet, though there
3435 are a lot places where this can replace dynamically allocated
3436 tables and I will fix these places, later, to use SilcDList.
3437 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3438 and use TRQ internally).
3440 Also fixed some annoying warning messages that the original TRQ
3441 code generated. Also minor changes to TRQ's Makefile.in.
3443 * Added support for querying by Client ID to both WHOIS and
3444 IDENTIFY commands into server, as required by the protocol.
3446 * Removed method function pointers from SilcBuffer structure. They
3447 weren't used to anything and just increased the context size for
3448 no good reason. This change also made silc_buffer_alloc and
3449 silc_buffer_free functions inline functions.
3451 * Disabled command flooding detection support until it's fixed so
3452 that it accepts commands in but does not execute them more than once
3455 * Added silc_net_localhost(), to return local hostname, into
3456 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3457 that must be initialized before calling silc_client_init.
3459 * Added new function: silc_server_send_notify_on_channels to send
3460 notify messages to all channels client has joined. It is assured
3461 that the message is sent only once per client.
3463 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3464 lib/silcutil/silcutil.[ch] as silc_format function. The new
3465 function is generic and is used by server as well, not only by
3466 the logging routines.
3468 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3469 the provided version string was not acceptable. Added new function:
3470 silc_ske_check_version into lib/silcske/silcske.h. The function
3471 must be implemented by the application (client or server) and it
3472 does not reside in the SKE library. The function checks the version
3473 string remote end sent.
3475 * Added back pointers (to opaque context and to SilcSocketConnection)
3476 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3478 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3479 duplicate packet context structure.
3481 * Changed `notify' client operation to send same arguments as client
3482 receives from server except for ID's. ID's are mapped to correct
3483 ID entry and that is returned. Also, if channel entry is not sent
3484 by server but the notify is for channel the channel entry is sent
3485 to application (otherwise application doesn't know that it is for
3486 channel (library gets it from packet's Destination ID)).
3488 * Added silc_client_remove_from_channels into client library to
3489 remove a client from all channels it has joined to. Used when
3490 received SIGNOFF notify from server. Added also new function
3491 silc_client_replace_from_channels to replace old ID entry with
3492 new ID entry on all channels. Used when received NICK_CHANGE
3495 * Fixed ID Cache list handling in silc_idlist_get_client in
3496 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3497 to get (or query) client by ID.
3499 * Updated TODO list.
3501 * Added connection authentication status message defined by the
3502 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3503 support for these into the code in client and server side.
3505 * Added generic function silc_client_send_command to send any command
3506 with variable argument list. Application should use this function
3507 to send commands if the command functions provided by the library
3508 does not suite for the application's user interface needs.
3510 * Added new `failure' client operation. Application is notified about
3511 received failure packet if client is executing a protocol. In this
3512 case the protocol's execution has failed.
3514 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3515 is required by the protocol.
3517 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3518 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3521 * Added status flag to SilcSKE object to indicate realtime status
3522 of the SKE protocol.
3524 * Application receives now exactly same command reply arguments as
3525 the library receives from server. However, if ID is received the
3526 corresponding ID entry is returned to the application (eg. Client
3527 ID is mapped to correct SilcClientEntry entry and that is returned).
3528 Changed command_reply client operation due to this change.
3530 * Changed all ID's in commands and in command replys as ID Payloads.
3531 Change affected both client and server side codes.
3533 All ID's sent in SILC network (with execption of ID's in SILC
3534 Packet header) are sent in ID Payload to support variable length
3537 * Server now notifies nick changes and notifies all clients on
3538 the channels about the new nickname (about the new Client ID,
3541 * Implemented CMODE command to change channel modes. Supports all
3542 channel modes defined by the protocol specs except ban and invite
3543 lists. (Also, private channel key mode is supported but support for
3544 setting private channel key in client is missing, thus, this mode
3545 has no effect on client side (except that server requires that the
3546 client uses private channel key and normal channel traffic does not
3549 Also, invite mode works per se, but INVITE command does not work
3550 yet correctly, so you can set channel as invite only channel but
3551 inviting clients to the channel does not work (it is yet to be
3552 thought what's the best way to do it).
3554 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3555 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3556 Implemented CUMODE command to change user's mode on the channel.
3557 Supports all modes defined by the protocol specs.
3559 * Added NAMES command reply to return users modes on the channel.
3561 * Removed unnecessary and slow ciphers from lib/silccrypt.
3563 * Set SO_KEEPALIVE option to connection sockets by default.
3565 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3567 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3568 redefined the Notify Payload into protocol specs.
3570 * Added silc_id_payload_parse_id to get ID directly from raw
3573 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3575 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3576 accept searching by Client ID as well.
3578 * Added support for LEAVE and SIGNOFF notify types in client library.
3580 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3581 to parse ID Payload from raw data.
3583 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Added flags parameter into silc_ske_assemble_security_properties
3586 function in lib/silcske/silcske.[ch].
3588 * Changed notify client operation to fit better for notify messages
3589 sent by server. The notify payload received from server is now
3590 passed to the application (after parsing it to SilcNotifyPayload).
3591 It is application's responsibility to retrieve the arguments
3592 from the payload and show the message the way it wants. The message
3593 sent by server is implementation specific.
3595 * Changed public keys to comply with the protocol specification.
3596 Old public keys are not supported anymore and are not compatible.
3598 * Removed nickname from Channel Payload as the latest draft removed
3599 it. The client must resolve the nickname from the NAMES command
3600 reply received when it joined the channel.
3602 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3604 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Fixed some errors in protocol specification drafts.
3608 * Created lib/silccore/silcnotify.c to implement Notify Payload
3609 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3610 generic payloads described by protocol specifications. The file
3611 includes implementations for ID Payload and Argument Payload.
3613 * Changed Command Payload implementation to use the new Argument
3614 Payload. Changed command_xxxx_payload to command_payload_xxxx
3615 to comply with SILC coding conventions.
3617 * Added suppport for Argument Payload handling in Notify Payload
3618 implementation as protocol requires it. Added the new support
3619 into server and client lib as well.
3621 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3623 * Added support for multiple nicknames on same channel. [n] is
3624 added locally to the nickname if there are more than one same
3625 nicknames on the channel.
3627 * Server now sends all nicknames that matched WHOIS request.
3628 Client also shows the list received from server.
3630 * Added TOPIC command to client side. User can now set and show
3631 current topic on channel.
3633 * Added MOTD command to client and server. Also, server sends the
3634 motd when client connects to the server.
3636 * Changed version strings to comply ISO 8601.
3638 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Fixed protocol error handling in client library. It should now
3641 cope even if the SKE fails for some reason.
3643 * Made new protocol specification drafts for submitting to IETF.
3645 * Implemented TOPIC command to server in silcd/command.c.
3647 * Added two new notify types into lib/silccore/silcnotify.h:
3648 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3649 notify nickname change and topic setting/change on a channel.
3651 * API change of command_reply operation in client library. The
3652 application gets now the status type received from server as well.
3654 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3656 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3658 * Cras fixed and optimized the packet handling even further and
3659 it should work now. Minor change to the prototype of function
3660 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3662 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Added new function into lib/silcutil/silcschedule.[ch]:
3665 silc_schedule_with_fd to select() a specified fd. The function
3666 returns after timeout expires or data arrives or goes. The
3667 function is used by packet routines to wait that all data is
3668 received from network.
3670 * Fixed data reading from network in lib/silccore/silcpacket.c.
3671 The code now assures that all data is read from the fd and then
3672 continues packet processing. This was a bug fix since the code
3673 used to drop some data in some circumstances.
3675 * Added new function into lib/silcclient/client.[ch]:
3676 silc_client_start_key_exchange to start key exchange after
3677 connection has been established to server. The code internally
3678 now uses this funtion but its main purpose was to provide it
3679 for applications that perform their own connecting. After
3680 application has created a connection it merely calls this
3681 function to start the key exchange between client and server.
3682 The library takes care of everything else after that.
3684 Updated also lib/silcclient/README to explain the usage of
3687 * Do not send to application information that connection has
3688 been established. Application gets notified it by connect
3691 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3693 * Applied cras's patch to add silc_schedule_one function. The
3694 function runs scheduler once and returns.
3696 * Fixed the scheduler after cras messed it up. The timeout
3697 handling works now as it's supposed to work.
3699 * Added into lib/silccore/ silcnotify.h to include notify
3700 message types support. Changed silc_server_send_notify*
3701 functions, in server.[ch], to support those new notify types.
3702 Added the support for the notify types into client library,
3703 as well. Added new notify client operation into ops.h in
3706 * Changed silc_server_packet_send_to_channel to send normal
3707 packets instead of just channel message packets. The function
3708 is now used to send the notify packets to channels. It is not
3709 used to send channel message packets anymore, as server never
3712 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3713 va_arg()s as it seems to require it nowadays. I guess, if SILC
3714 is compiled with older va_arg() the new code should work anyway.
3716 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Splitted core library. Core library (lib/silccore) includes
3719 now only SILC protocol specific core (and common) components.
3720 Created new utility library (lib/silcutil) that includes more
3721 generic purpose stuff. The stuff for util library was taken
3722 from the old core library. This was minor and easy split.
3724 * Created SILC Client Library (lib/silcclient) that includes
3725 implementation of the SILC client without user interface. This
3726 was major move from silc/ directory. The code has been changed
3727 so that it is transparent towards the user interface. The
3728 silc/ directory includes now the same user interface as before
3729 and it uses the new client library. Read lib/silcclient/README.
3730 Basicly, the client library performs everything else related
3731 to SILC except user interface handling. Also, configuration
3732 files are considered to be part of user interface and library
3733 does not handle them.
3735 This change also changed a lot of structures, function naming etc.
3736 Most important change was that SilcClientWindow object was
3737 renamed to SilcClientConnection in the client library. Created
3738 also new file lib/silcclient/ops.h. Also added new files
3739 silc/local_command.[ch] and silc/client_ops.[ch].
3741 All these changes were made to make it easier for user interface
3742 designers to create what ever user interface for the SILC client
3745 It is also expected that the server will be moved to lib
3746 directory as well and SILC Server Library will be created;
3747 sometimes in the future.
3749 * Removed Local commands from lib/silccore/silccommand.h as
3750 they are application specific and new client library does not
3751 handle any of those anymore.
3753 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3754 old client implementation in silc/.
3756 * Added support for callback functions in SILC_LOG_* macros.
3757 Application can now set its own callbacks that will be called
3758 instead of using the default functions that will always print
3759 the debug messages to stderr (or stdout). Also, debugging can
3760 now be disabled by setting silc_debug to FALSE and re-enabled by
3761 setting it to TRUE. Note, that logging will still work even
3762 if debugging is disabled.
3764 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3765 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3766 silc_log_reset_debug_callbacks.
3768 * To enable debugging in silc client one must give now -d
3769 option on command line.
3771 * Changed silc_schedule_init to automatically allocate task queues
3772 if they are not allocated before calling it.
3774 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Added GMP 3.1 into math library.
3778 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3781 a channel in SILC network. The packet is used by servers and
3782 routers to notify other routers that user has left a channel.
3783 This little feature was missing until now. Added the feature
3784 to protocol specification as well.
3786 Added functions: silc_server_send_remove_channel_user and
3787 silc_server_remove_channel_user into server.[ch].
3789 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3790 lib/silccore/silcpacket.h. However, they are not implemented
3793 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3795 * Fixed joining to a channel and sending channel messages
3796 between server and router. The channel message sending should
3797 now work inside a cell.
3799 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * Fixed the private message sending between server and router.
3802 The private message sending should now work inside a cell.
3804 * Added silc_server_replace_id into server.[ch] to replace
3805 existing ID in the SILC network.
3807 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3808 and silc_idlist_replace_server_id into idlist.[ch] in server.
3810 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Fixed the server to server connections. Server can again now
3813 connect to router. Router to router connections probably does
3816 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3818 * Added dynamic protocol registering support. Now protocols can
3819 registered and unregistered on the fly. Patch by cras.
3821 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Added lib/contrib directory to hold routines that some platforms
3824 don't have but are needed by SILC.
3826 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3827 into lin/contrib to provide getopt() and getopt_long() for
3828 those who don't have it.
3830 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Added AWAY command to client. When away message is set and
3833 client receives a private message packet the client automatically
3834 replies to the sender with the away message.
3836 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3837 bug seemed to be the cause of recent problems when compiling
3840 * Added version detection support to SKE protocol specification
3841 and added the new changes to the SKE implementation as well.
3842 There were other minor changes in the SKE protocol as well.
3844 Many changes in lib/silcske/silcske.[ch] and in
3845 lib/silcske/payload.[ch].
3847 * Added ^U functionality, clear input line. Patch from cras.
3849 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Mainly small bugfixes on core library. Fixed some debugging
3852 logging and buffer overflow in silclog.c.
3854 * Updated config.sub and config.guess on the distribution tree.
3856 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * Added command lagging support in server. Client may execute
3859 commands now only once in two seconds.
3861 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3863 * Optimized packet reception. MAC computation and checking is now
3864 also more optimized. A lot previously duplicated code is now
3865 used as generic by both client and server.
3867 * Fixed key pair generation in clientutil.c
3869 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Added into lib/silccore/silcbufutil.[ch] new function;
3872 silc_buffer_realloc.
3874 * Moved generic packet sending/encryption functions to
3875 lib/silccore/silcpacket.[ch] from client and server. Some
3876 rewriting of the functions.
3878 * Moved all generic packet reception/decryption functions to
3879 lib/silccore/silcpacket.[ch] from client and server. The
3880 packet processing is now much cleaner in both client and server.
3881 These were major changes in both client and server.
3883 * Created many common functions in server to do packet sending.
3884 Previously code were duplicated a lot, this has been removed
3887 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Rewrote major parts of the ID cache system. Don't know
3890 whether it is better now or not but at least the API is more
3893 * Major rewrite on ID cache stuff on client because of the ID
3894 cache API changes. Added idlist.c to client.
3896 * Also major rewrite on ID cache stuff on server as well.
3897 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3898 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3899 in hand, instead they are all put into the ID cache system now.
3900 All server_idlist_* routines uses ID cache now instead of
3901 traversing its own lists (those lists does not exist anymore).
3902 SilcIDList though still exists. Also, SilcXXXEntry's are
3905 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3907 * Finally made the SKE implementation compliant to the protocol
3908 specification. All mp integers are now binary encoded as
3909 opposed being HEX encoded.
3911 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3914 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3915 functions: silc_[encode/decode]_pem. Also added function
3916 silc_encode_pem_file to PEM encode with newlines ('\n') for
3919 * SILC public keys are now encoded either PEM or binary. Same
3920 option is for private keys as well. By default private keys
3921 are binary encoded and public keys PEM encoded. Silly HEX
3922 encoding were removed.
3924 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3925 function to create fingerprints.
3927 * Fixed a bug in SHA1; does not change the original data anymore.
3929 * Partly implemented INFO command on client and server side.
3930 Fixed CLEAR command. Changes to SERVER command; show current
3931 server(s) when giving command without arguments. Added
3932 VERSION command to client.
3934 * Added check to server that unregistered connections cannot
3935 execute commands (unless it is specificly allowed).
3937 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * Fixed screen refresh.
3941 * Fixed channel joining bug from client. On some circumstances
3942 client tried to join to a channel it had already joined.
3944 * Added public key verification process into client's protocol.c.
3945 The client now verifies the public key from user and saves
3946 it into ~./silc/serverkeys/ directory.
3948 Added into: clientutil.[ch]: silc_client_verify_server_key.
3950 * Changed SKE protocol's silc_ske_initiator_finish function
3951 to accept callback function that verifies the received public
3952 key. Removed old silc_ske_verify_public_key function.
3954 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3957 silc_pkcs_private_key[_data]_set.
3959 * Made the password and public authentication more cleaner in
3960 server's protocol.c.
3962 * Removed historic and obsolete protocol `channel_auth' from
3963 both client and server.
3965 * Removed wrong way of sending command status messages from
3966 server to client in server's command.c. The old way violated
3967 protocol specification.
3969 Changes to silccore/silccommand.[ch]: removed
3970 silc_command_encode_status_payload -> not needed anymore,
3971 changed silc_command_encode_payload_va to accept extra
3972 argument on variable argument list. The argument type must
3973 now be provided to the function. Also, added new function:
3974 silc_command_encode_reply_payload_va which is same as
3975 normal command_encode_payload_va except command status type
3976 is provided as extra argument.
3978 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Added ~./silc directory handling. The directory includes the
3981 public and private keys for the client.
3983 Added silc_client_check_silc_dir, silc_client_create_identifier
3984 and silc_client_load_keys.
3986 * Implemented SILC protocol compliant public key. Added public
3987 and private key saving to and loading from files.
3989 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3990 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3991 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3992 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3993 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3995 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3996 silc_pkcs_load_[public/private]_key.
3998 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Added silc_server_get_route (route.[ch]) to get connection
4001 data for the fastest route for given ID.
4003 * Implemented INVITE command on client and server. The command
4004 were re-defined in the SILC Protocol Specification and the
4005 implementation now complies with the specification.
4007 * Implemented PING command on client and server.
4009 * Implemented NAMES command on client and server. The server side
4010 supports currently only normal server not router server yet.
4011 Some changes to NAMES definition in SILC protocol specification.
4013 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Implemented LEAVE command on client and server.
4017 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4018 again. This change was made to the protocol as well. Server
4019 should not violate the protocol specification anymore.
4021 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4023 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4024 was tested. SOCKS4 was not but should work anyway.
