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 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Added the server's public key sving and verification to the
9 server when performing the SKE. This was missing and the
10 remote server's (or router's) public key was accepted without
11 checking whether we have it previously or trust it at all.
12 Affected file silcd/protocol.c.
14 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
16 * Check in the silc_server_timeout_remote if protocol is active
17 and make sure that the protocol's final callback is called so
18 that all memory if freed. Affected file silcd/server.c.
20 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
22 * silc_server_whois_send_reply crashed the server if the nickname
23 was 127 characters long. Affected file silcd/command.c.
25 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
27 * Added sanity check to the silc_server_new_client. If the hostname
28 is provided inside username then check that the provided hostname
29 really is the same as the resolved one. If the hostname was not
30 resolved then check it from the public key. Affected file is
31 silcd/packet_receive.c.
33 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
34 if the server disconnected us and the connection is not valid
35 anymore. Affected file irssi/src/silc/core/silc-channels.c.
37 * Moved the silc_client_[chmode|chumode|chumode_char] away from
38 the library to the lib/silcutil/silcutil.[ch].
40 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
42 * Close log file after open. Affected file
43 lib/silcutil/silclog.c.
45 * Check whether sock == NULL in silc_client_send_packet and return
46 if it is. Affected file lib/silcclient/silcclient.c.
48 * Check rec->entry == NULL in the Irssi SILC Client before
49 sending the channel message. Affecte file is
50 irssi/src/silc/core/silc-servers.c.
52 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
54 * Merged a splitted window bugfix from Irssi CVS tree. The
55 affected file is irssi/src/fe-text/textbuffer-view.c.
57 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
58 It did not print nickname.
60 * Improved the distributions system a bit.
62 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
64 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
65 irssi/src/fe-text/gui-window.c.
67 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
68 to in-active server. The affected file is
69 irssi/src/silc/core/client_ops.c.
71 * Resolve the client in USERS command reply if the entry does
72 not have username resolved. The affected file is
73 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
74 command to WHOIS command to really resolve stuff. The USERS
75 is not used any more in any critical section so WHOIS can
76 be used even though it might be slower than IDENTIFY.
78 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
81 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
83 * Changed the protocol API a bit more consistent in the
84 lib/silccore/silcprotocol.[ch].
86 * Changed the following headers to ROBODoc format:
88 lib/silccore/silcpayload.h
89 lib/silccore/silcprotocol.h
90 lib/silccore/silcsockconn.h
92 All core library headers are now formatted.
94 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
96 * Fixed a bug in Irssi SILC client; do not show that you are
97 server/router operator if you really are not. Affected file is
98 irssi/src/silc/core/client_ops.c.
100 * Renamed silc_command_free_payload to silc_command_payload_free.
101 Affected file lib/silccore/silccommand.h
103 * Added silcmath.h to include the prototoypes of various routines
104 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
107 * Changed the following headers to ROBODoc format:
109 lib/silccore/silcchannel.h
110 lib/silccore/silccommand.h
111 lib/silccore/silcid.h
112 lib/silccore/silcidcache.h
113 lib/silccore/silcmode.h
114 lib/silccore/silcnotify.h
115 lib/silccore/silcpacket.h
116 lib/silcmath/silcmath.h
118 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
120 * Added checking to the server code not to start the server if
121 ciphers and stuff are not configured properly. Affected files
122 silcd/serverconfig.[h] and silcd/server.c.
124 * Changed the layout of the header files of the public interfaces
125 in the SILC libraries. The new layout supports ROBODoc
126 documentation tool (and some others) so that it is easy to create
127 a library reference manual. All the other headers and source
128 code must still follow the CodingStyle document. Also source
129 code must not include these ROBODoc stuffs, only the headers.
130 Furthermore, all public interface headers must now be named
131 by using `silc' prefix, example: silcapi.h, silccipher.h.
132 Some files were renamed due to this. All the other headers
133 must not be used as public interfaces. I will update the
134 CodingStyle document later. Changed following headers, so far:
136 lib/silcclient/silcapi.h
137 lib/silccore/silcauth.h
138 lib/silccore/silcprivate.h
139 lib/silccrypt/silcdh.h
141 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
145 * Removed silc_client_packet_send_flush from the client library
146 as it is not needed. Affected file lib/silcclient/client.[ch].
148 * Added printing of message of unresolved authentication method
149 to the Irssi SILC client. Added it to the module formats.
150 Removed the same message from the client library.
152 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
154 * Added new distribution feature, DISTLABEL. Every distribution
155 can define own preprocessor label that can be used in the
156 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
157 file distributions, acconfig.h.pre and prepare.
159 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
161 * Added Makefile.defines_int to include the actual definitions
162 for Makefile.defines.in. Tested the new distribution system,
163 created distributions and tested installation.
165 * Added AWAY message printing to the Irssi SILC client. Added
166 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
168 * Added SCONNECT command to call the SILC's CONNECT command.
169 Cannot use CONNECT directly since Irssi uses that internally.
170 Affected file irssi/src/silc/core/silc-servers.c.
172 Added ACTION local command. It is same as ME command but takes
173 the channel as mandatory argument.
175 Rewrote some of the Irssi's help files to suite for SILC
178 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
180 * Added Makefile.defines[.in] that should for now on be included
181 in all Makefile.am file in the source tree. That file includes
182 all common compilation definitions for SILC source tree.
184 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
186 * Minor changes to the ./prepare script to change the package
187 name according the distribution name to the configure.in.
189 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
191 * Created new distribution system. Added file `distributions'
192 that defines all the distributions that can be created out of
193 the SILC source tree. The ./prepare script now reads that
194 file to determine how to prepare the distributions. The
195 first argument to the ./prepare is the name of the distribution
196 and second is the version of the distribution. If given
197 without arguments it creates the default (toolkit) distribution
198 with the default version (defined in ./prepare).
200 All Makefile.am files that are subject to the distributions
201 are now named as Makefile.am.pre. These are ./Makefile.am
202 and lib/Makefile.am. Others may be changed later.
204 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
206 * Added invite list, ban list, some key management and connection
207 error message printing to module formats in the Irssi SILC client.
209 * Added new silc_client_set_away_message to set the away message
210 that is back to the person who sent private message. The
211 affected file lib/silcclient/silcapi.h and the
212 lib/silcclient/client_prvmsg.c.
214 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
216 * Fixed the private message sending in the Irssi SILC client,
217 added local command KEY to the Irssi SILC client.
219 Added key management and key agreement message formats to the
220 irssi/src/fe-common/silc/module-formats.[ch].
222 Added USERS (alias WHO) printing, server/router operator
223 indication and LIST command printing to the module formats.
225 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
227 * Fixed channel joining notify handling, cumode notify handling
228 from Irssi SILC client.
230 * Added SILC specific module-formats to the Irssi SILC client so
231 that SILC specific message hilighting, colors etc is possible.
232 Affected file irssi/src/fe-common/silc/module-formats.[ch].
234 Added channel mode, channel user mode, actions, notices,
235 whois and whowas printing to the the module-formats.c.
237 * Fixed a bug in channel deletion in the server. The channel
238 is not left to the cache even if the channel founder auth mode
239 is set when there are no users anymore on the channel. Affected
242 * The silc_net_localhost now resolves the entire hostname including
243 the domain name. Affected file lib/silcutil/silcnet.c.
245 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
247 * Changed the ask_passphrase client operation to be ascynchronous.
248 It has now a completion callback and a context that the
249 application must call after it has got the passphrase from
250 the user. Affected files lib/silcclient/silcapi.h,
251 lib/silcclient/protocol.c, lib/silcclient/command.c and
254 Added SilcAskPassphrase callback that the application calls
255 to deliver the passphrase to the library.
257 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
258 The public key verification and especially a certificate
259 verification is asynchronous procedure.
261 Added new SILC_SKE_STATUS_PENDING status to indicate the
262 request is pending and a callback will be called to finalize
265 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
266 indicate that remote end did not send its public key (or
267 certificate), even though we require it. Added check for this
268 condition in the SKE. This was a security bug, now fixed.
270 Defined new SilcSKEVerifyCbCompletion callback that is called
271 when the verification process is completed.
273 The affected files lib/silcske/silcske_status.h and
274 lib/silcske/silcske.[ch].
276 * Changed the verify_public_key client operation to be async
277 as well. Defined SilcVerifyPublicKey callback that is used to
278 indicate the success of the public key verification process.
280 Changed the server and client to use the new async client
283 * Changed the Irssi SILC client's internal scheduler to be called
284 twice as many times as it used to be. As a result the client
285 should be a bit faster now. Affected file is
286 irssi/src/silc/core/silc-core.c.
288 * Added support to Irssi SILC client of asynchronous public key
289 verification and passphrase inquiry. Affected file is
290 irssi/src/silc/core/silc-core.c.
292 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
294 * Do not say "You have left channel %s" in client library.
295 Moved it to the application. Affected files are
296 lib/silcclient/command.c and silc/client_ops.c.
298 * Fixed silc_client_get_clients. Command context was not
299 duplicated and was freed memory in the callback. Affected
300 file lib/silcclient/idlist.c.
302 * Do not say "you are now talking..." on JOIN command in the
303 client library. The appliation must handle it.
305 * Do not say ".. changed topic to" in command reply in the
306 client libary. The application must handle it.
308 * Fixed TOPIC command sending in the client library.
310 * Fixed a memory leak in silc_client_command_free in the file
311 lib/silcclient/command.c.
313 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
315 * Imported a modified version of Irssi client to the source tree.
316 The Irssi will be used to create a new client called
317 Irssi SILC. Imported to irssi/.
319 Added silc_core_init_finish function to the Irssi. Affected
320 file irssi/configure.in.
322 A lot changes in the Makefile.ams around the irssi tree.
324 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Do not rehash if the new size is same as the old size of the
327 hash table, in the silc_hash_table_rehash*. The affected file
328 lib/silcutil/silchashtable.c.
330 * Replaced hash_table_del_by_context calls from the server
331 (when channel->user_list and client->channels) to the
332 hash_table_del as it is sufficient and faster.
334 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
336 * Added silc_hash_table_list, silc_hash_table_get and the
337 SilcHashTableList structure to provide an alternative way to
338 traverse the hash table. The affected files are
339 lib/silcutil/silchashtable.[ch].
341 * Changed the server's idlist routines to use the hash table
342 routines to optimize the code.
344 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
346 * Replaced the client entry's `channel' list and channel entry's
347 `user_list' list to hash tables for optimized lookup. Changed
348 the code to use the hash table interface around the code.
349 Affected file lib/silcd/idlist.[ch].
351 * Added `auto_rehash' boolean argument to the function
352 silc_hash_table_alloc to indicate whether the hash table should
353 auto-rehash when it thinks is appropriate time. It will
354 increase the hash table size if the there is twice as much
355 entries in the table than the size of the table, and will
356 decrease the size if there are twice as less entries than
357 the size of the table.
359 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
361 * Fixed silc_xxx_get_supported to not crash at some circumstances.
363 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
365 * silc_idcache_purge_by_context deletes the entry now by context
366 as it is supposed to do. Affected file lib/silccore/idcache.c.
368 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
369 client is not anymore valid (WHOWAS givens the info) and not
370 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
372 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
374 * Removed the `data' and `data_len' arguments from the ID Cache
375 interfaces and added `name' argument. ID Cache does not handle
376 anymore the binary data only a names associated with given ID.
378 * When hashing a Client ID with silc_hash_id the entire ID is
379 not hashed anymore, instead only the hash of the Client ID is
380 hashed. This way we can access the Client ID from the cache
381 with Client ID but with the hash of the ID (which is a hash of
382 the nickname) as well without any difference in performance.
384 Added also silc_idcache_find_by_id_one_ext to do one on one
385 searching when we have the actual ID. Added also function
386 silc_hash_client_id_compare. The affected files are
387 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
389 * When hashing the name associated with a ID it is always done
390 in lowercase. This way we can access the cache without worrying
391 about case-sensitivity, even though, for example nicknames are
394 * Fixed a bug in server with channel message sending. It put
395 wrong ID type as destination ID. The affected file
398 * silc_idcache_del_by_context now deletes from all hash tables
399 by context. Affected file lib/silccore/idcache.c.
401 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
403 * Changed the client library to use the new ID Cache interface.
404 Changes around the source tree.
406 * Added silc_hash_table_rehash_ext to rehash with specific
407 hash function. Affected file lib/silcutil/silchashtable.[ch].
409 * Added silc_hash_string_compare to compare two strings in the
410 hash table. Affected file lib/silcutil/silcutil.[ch].
412 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
414 * Added new function silc_idcache_del_by_context into the
415 lib/silccore/idcache.[ch].
417 * Changed the server's ID list routines to use the new ID Cache
418 interface. Changes around the source tree.
420 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
422 * Added silc_hash_table_del[_by_context]_ext functions in to the
423 lib/silcutil/silchashtable.[ch].
425 Removed silc_hash_table_find_all* routines and added new
426 silc_hash_table_find_foreach to replace them.
428 Added silc_hash_table_replace_ext function as extended
429 replacing function. Separated the simple hash table interface
430 from the extended hash table interface in the file
431 lib/silcutil/silchashtable.h.
433 * Fixed minor bugs and changed it to use some of the new
434 hash table functions in lib/silccore/idcache.c
436 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
438 * Added new function silc_hash_table_find_all to return all keys
439 in the hash table by the specified key. As the hash table is
440 collision resistant it also makes it possible to have several
441 duplicate keys in the hash table. This function may be used to
442 find all of the keys from the hash.
444 Added user_context arguments to the SilcHashFunction,
445 SilcHashCompare and SilcHashDestructor to deliver user specified
448 Added new fuctions silc_hash_table_find[_all]_ext to do
449 extended lookup with specified hash and compare functions and
450 specified user contexts.
452 Added new function silc_hash_table_add_ext to add the key
453 with specified hash function and user context.
455 Added new function silc_hash_table_foreach to traverse all
456 entrys in the hash table. Added SilcHashForeach callback
459 Added new function silc_hash_table_del_by_context to delete
460 the entry only if the context associated with the key matches.
462 Affected files are lib/silcutil/silchashtable.[ch].
464 * Removed silc_hash_[server/client/channel]_id and added just
465 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
466 silc_hash_id_compare to compare two ID's using as the hash table
467 comparison function. Added also silc_hash_data to hash
468 binary data and silc_hash_data_compare to compare it.
470 * Removed silc_idlist_find_client_by_hash as it is not needed
471 anymore. Affected file silcd/idlist.[ch].
473 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
474 to use internally the SilcHashTable. The new ID Cache is a lot
475 faster than the old one. Some of the ID Cache interface was also
476 rewritten and obsolete and stupid functions were removed.
478 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
480 * Added entry_count field to the SilcHashTable to keep the number
481 of the entries in the table. Implemented the function
482 silc_hash_table_rehash. Added new function
483 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
485 Fixed a minor bug in silc_hash_table_free.
487 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
488 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
489 into the lib/silcutil/silcutil.[ch].
491 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Implemented a collision resistant hash table into the
494 lib/silcutil/silchashtable[ch]. See the header and the source
495 for the SilcHashTable API.
497 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
499 * Merged dotconf version 1.0.2 into lib/dotconf.
501 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
503 * Do not compile anything in lib/silcsim/* if the SIM support
504 is not enabled. The tree should now compile without problems
507 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
509 * Compiled the SILC under cygwin. Compiled and tested briefly
510 without problems. More tests needed. The SIMs didn't compile
513 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
515 * Fixed possible crash in silc_get_username in the
516 lib/silcutil/silcutil.c.
518 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
520 * Fixed a va_arg in silc/client_ops.c.
522 * Oops, RC5 routines were named AES and caused some problems
523 when not using SIM's. Affected file lib/silccrypt/rc5.c.
525 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
527 * Added new SilcIDIP structure into the lib/silccore/id.h and
528 replaced the old `ip' fields from all SILC ID's to that type.
529 This is a step towards IPv6 support.
531 The silc_id_get_len takes now the ID as an extra argument.
532 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
533 both IPv4 and IPv6 based ID's.
535 The affected files are lib/silccore/id.[ch] and other files
536 around the tree using these routines.
538 * Removed the ID length arguments in server from various
539 silc_server_send_notify_* routines -> they are not needed
542 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
544 * Fixed memory leak in silc_encode_pem_file in the file
545 lib/silcutil/silcutil.c.
547 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
549 * Check minor version as well in the SKE. Affected files are
550 silcd/protocol.c and lib/silcclient/protocol.c.
552 * Added --identifier option to the server so that an identifier
553 can be when creating the public key for the server. Affected
554 file is silcd/silcd.c.
556 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
557 lib/silccrypt/silcpkcs.c.
559 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
561 * Register default ciphers and stuff when using -C option with
562 the server. Affected file sildc/silcd.c.
564 * Put back the servers public key filename format, it is better
565 than the new one. For now, the client keys are saved with the
566 new filename format. The affected file silc/client_ops.c.
568 * Implemented the Cipher API for the rest of the ciphers that
569 did not implement it or implemented it the wrong way.
571 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
573 * Register default ciphers and stuff when using the -S option
574 in the client. Affected file silc/silc.c. Same also when
575 creating new key pair with -C option.
577 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
579 * Fixed the silc_verify_public_key client operation function to
580 save the public keys differently. The fingerprint is now
581 used as filename and not the hostname. This way also the
582 client keys are saved uniquely and not with hostnames. The
583 affected file is silc/client_ops.c.
585 * Trimmed the silc_hash_fingerprint function to remove extra
586 whitespaces from the end of the fingerprint. The affected
587 file is lib/silccrypt/silchash.c.
591 * Added silc_cipher_register_default function to register all
592 default ciphers. It can be used when configuration files
593 does not exist and the application does not want any specific
594 ciphers in any specific order.
596 The SilcDList is now used as silc_cipher_list dynamically
597 allocated cipher list. Removed the static list all together
598 and now all ciphers must be allocated to the dynamic list.
599 The silc_cipher_alloc routine was changed to check only the
602 All silc_cipher_* routines that used to return int returns
605 The affected files lib/silccrypt/silccrypt.[ch].
607 * The same thing was done to silc_hash_* as for silc_cipher_*
608 routines. Affected files lib/silccrypt/silchash.[ch].
610 * The same thing was done to silc_pkcs_* as for silc_cipher_*
611 routines. Affected files lib/silccrypt/silcpkcs.[ch].
612 Added also silc_pkcs_[un]register[_default] functions.
613 Removed the data_context from the PKCS API.
615 * Added silc_hmac_register_default function to register default
616 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
617 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
618 to unregister all hmacs at once.
620 * Register the default ciphers, hash functions, PKCSs and HMACs
621 if client's configuration file does not exist. The affected
624 * The client did not load the hash functions from the SIM
625 modules at all. Added support for this. Affected file is
628 * When decoding public key with silc_pkcs_public_key_decode, check
629 the supported algorithm only if PKCS are registered. Affected
630 file lib/silccrypt/silcpkcs.c. The same was done with the
631 silc_pkcs_private_key_decode.
633 * Fixed the SILC List routines to keep the list always in order.
634 It used to change the list's order when traversing the list but
635 not it preserves the order. Affected file lib/trq/silclist.h.
637 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
639 * Added the client library to use the SilcSocketConnection's
640 reference counter (by silc_socket_dup) to prevent the bug that
641 the socket object may be freed underneath async operation.
643 * The name resolv library checking fixes in the configure.in.pre.
646 * Created new version of the protocol drafts for future
647 development. The -03 drafts are the ones that will be changed
648 in the trunk now and the -02 will remain as they are.
650 * Send list of CUMODE notifys to the router when announcing
651 the channel users to the router. Affected file silcd/server.c.
652 If the router receiving channel founder CUMODE for a channel
653 that already has channel founder it will send CUMODE notify
654 to the sender to remove the channel founder rights from the
655 announced client. Affected file silcd/packet_receive.c.
657 * The CUMODE notify may now use Server ID as well as the entity
658 who changes the mode. Updated protocool specs.
660 * Updated INSTALL and README files.
662 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
664 * New web pages in the http://silc.pspt.fi. The pages was
669 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
671 * Implemented the [DenyConnectin] config section in the server.
672 Added silc_server_config_denied_conn to check whether incoming
673 connection is denied. Affected file silcd/serverconfig.[ch].
675 * Do not check the ports when checking the incoming configuration
676 data if the port is 0, meaning any. Affected file is
677 silcd/serverconfig.c.
679 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
681 * Fixed buffer overflow in silc_string_compare in the file
682 lib/silcutil/silcutil.c.
684 * Fixed double free in silc_server_command_leave in the file
687 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
689 * Fixed the version checking in the server. Affected file is
692 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
694 * Fixed the configuration data fetching when accepting new
695 connections in the server. Affected file silcd/server.c.
697 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
699 * Added `sender_entry' argument to the function
700 silc_server_packet_relay_to_channel so that we can check
701 whether some destination actually belongs to the same route
702 the sender belongs (ie, we must not resend the packet to the
703 sender). Affected file silcd/packet_send.[ch].
705 * Added `servername' field to the SilcClientEntry in the server
706 to hold the name of the server where client is from. Affected
707 file is silcd/idlist.h.
709 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
711 * Moved the channel message encrypting in the router betwen
712 router connections from silc_server_channel_message to the
713 silc_server_packet_relay_to_channel since we want to check
714 whether we have anybody channel before encrypting anything.
715 Affected files silcd/packet_[receive/send].c.
717 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
719 * Fixed the [AdminConnection] server config section to support
720 multiple entries. Affected file silcd/serverconfig.c.
722 * Added support into the server to check the validity of the
723 incoming connection before executing any KE or authentication
726 * The connection configuration is now saved to the KE and
727 connection auth protocol contexts and not fetched anymore in
728 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
730 * The local hosts listenning address and port is also resolved
731 now when starting the server. We want to have the socket object
732 to include the real address and port for the listener. Added
733 new function silc_net_check_local_by_sock into the files
734 lib/silcutil/silcnet.[ch].
736 * Fixed a broadcast bug in server -> do not broadcast if we
739 * Fixed a routing bug. Do not route broadcast packets ever.
740 Broadcast packets must be processed always and not routed since
741 they may be destined to some other host than yourself and thus
742 would get routed without no good reason. Affected file is
745 * Added function silc_server_config_is_primary_route to check
746 whether primary router connection has been configured (a router
747 configuration that we are initiating). If there is not, we
748 will assume that there is only two routers in the SILC network
749 and we will use the incoming router connection as our primary
750 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
752 * Changed the order of the broadcasting. Broadcast _after_ the
753 packet has been processed not before. Affected file is
756 * Fixed a [ClientConnection] parsing bug. The port was never
757 parsed correctly thus resulting to port 0. Affected file
758 silcd/serverconfig.c.
760 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
761 argument and did not set the broadcast packet flag. Affected
762 file silcd/packet_send.c. Fixed same bug in the function
763 silc_server_send_notify as well.
765 * If we receive NEW_ID packet for our own ID in the server, ignore
768 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
772 * Removed the nickname from the Private Message Payload.
773 Updated the code and the protocol specs.
775 * Updated protocol specs for submitting to the IETF.
777 * Tweaked the Random Number Generator a bit. Affected file
778 lib/silccrypt/silcrng.c. Exported a new function
779 silc_rng_[global]_add_noise which can be used to add more
782 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
784 * Do not parse packets with different timeout when protocol
785 is active -> may cause problem with rekey. Affected file
788 * When server receives signoff notify it must not create
789 new channel key if the client is on any channels since the
790 sender of the signoff notify will create it.
792 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
794 * Added printing of error messages during SKE protocol from the
795 failure packet sent by server during SKE. Affected file
798 * Removed the client's failure_callback handling with timeout
799 and handle it immediately when received.
801 * The SKE library returned wrong type in SUCCESS and FAILURE
802 packets. They must be 32 bit MSB not 16 bit MSB.
804 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
806 * Ok, rewrote the logic of the re-key and now it seems to work.
807 I tested it on high traffic with frequent re-keys without
808 problems. Added hmac_receive (and renamed hmac to hmac_send)
809 in SilcClientConnection in lib/silcclient/client.h and
810 in SilcIDListData in silcd/idlist.h. Also, removed the
811 SilcPacketParserContext's cipher and hmac fields as they are
812 not needed anymore and actually caused some problems when
813 the ciphers and hmac's changed underneath the packet parser.
815 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
817 * If re-key protocol is active then process the incoming packets
818 synchronously since we must assure that icoming packets encrypted
819 with the old key is processed before the new keys is set to
820 use. This is true other packets than for REKEY packets.
821 Affected file silcd/server.c. The same was done to client library
822 as well, affected file lib/silcclient/client.c.
824 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
826 * Fixed bug in client and server to accept the force send if
827 the packet is send from silc_[server/client]_packet_process
828 function. Otherwise the packets are never delivered, oops.
830 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Disable force sending of packets when REKEY protocol is active.
833 We must assure that no packet is sent directly when rekey is
834 performed. All packets must be sent through packet queue.
835 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
836 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
837 function is silc_[server/client]_packet_send_real to check
840 * Replaced the SIM paths from example config files to
841 /usr/local/modules. Also, make install creates now
842 /usr/local/silc/logs directory to hold all the SILC server
845 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
847 * Made the configure.in.pre work on Solaris. Patch by salo.
849 * Made all ciphers compatible with non-x86 machines. Defined
850 CBC mode macros into lib/silccrypt/ciphers_def.h.
852 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * Fixed the make install.
856 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
858 * When MAC computation fails the silc_packet_decrypt returned 0
859 even though it was supposed to return -1. Fixed this. The
860 affected file is lib/silccore/silcpacket.c.
862 * Do not replace the config files in /etc/silc (in make install)
863 if they already exist. Affected file ./Makefile.am.
865 * Do not send re-key packets immediately but through packet queue.
866 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
868 * Changed silc_net_check_host_by_sock to return FALSE if the
869 IP/DNS could not be resolved. Though, it returns the IP address
870 now even if it could not resolve it (but returns also FALSE).
871 Affected file lib/silcutil/silcnet.[ch].
873 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
875 * Added silc_pkcs_decode_identifier to decode the public key's
876 identifier. Affected file lib/silccrypt/silpkcs.[ch].
877 Added also silc_pkcs_free_identifier. Added also new context
878 SilcPublicKeyIdentifier.
880 * Added -S option to the silc client. It is used to dump the
881 contents of the specified public key file.
883 * Changed the PKCS api to return the public key length when
884 setting the public key.
886 * Fixed a fatal bug in the public and private key file loading.
887 Affected file lib/silccrypt/silcpkcs.c.
889 * Execute the packet parsing for client with zero (0) timeout
890 if the protocol is active. Affected file silcd/server.c.
892 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
894 * Made the key generation options to the silcd program. Added
895 -C option, equivalent to client's option.
897 * Added new [ServerKeys] config section to the server. It
898 configures the server's public and private key.
900 * Defined generic Public Key Payload into the protocol
901 specification to send specific type of public keys and
904 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
905 public key or certificate.
907 * Implemented the GETKEY command to the server and to the
908 client library and on user interface.
910 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
912 * Made preliminary `make install' work.
914 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Added SilcServerRekey context into silcd/idlist.h.
918 * Added the PFS support as defined in the specification to the
919 SKE protocol. Affected files lib/silcske/*.c.
921 * Added `ske_group' field to the SilcServerRekey context to hold
922 the number of the SKE group that is used with PFS in re-key.
923 Affected file silcd/idlist.h.
925 * Added PFS re-key support to the server. Affected file is
928 * Added silc_protocol_cancel to cancel execution of the next
929 state of the protocol. Affected file is
930 lib/silccore/silcprotocol.[ch].
932 * Added the re-key support with and without PFS to the client
933 library. Re-key is performed once in an hour, by default.
935 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
936 Added silc_client_rekey_callback and silc_client_rekey_final.
937 Affected files are lib/silcclient/protocol.[ch] and
938 lib/silcclient/client.[ch].
940 * Removed the `hmac_key' and `hmac_key_len' fields from the
941 SilcClientConnection structure; not needed. Affected file is
942 lib/silcclient/client.h.
946 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
948 * Do not ask whether user wants to use the negotiated private key
949 for private messages, just use it. Affected file is
950 silc/local_command.c.
952 * Added `send_enc_key' and `enc_key_len' fields to the
953 SilcIDListData structure since they are needed in the re-key
954 phase. Affected file is silcd/idlist.[ch].
956 * Implemented the simple re-key protocol into the server.
957 Affected files silcd/server.c and silcd/protocol.[ch]. The
958 re-key will be performed once in an hour, by default.
960 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
961 Added silc_server_rekey, silc_server_rekey_callback and
962 silc_server_rekey_final.
964 * Removed Tunneled flag from the protocol. Updated the code
965 and the specifications.
967 * Adde `pfs' field to the SilcIDListData to indicate whether
968 the PFS is to be performed in the re-key. Affected file is
971 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
973 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
974 int64 of at least the xintXX size. If void * is less that 4
975 bytes uint32 * will be used. Defined bool as boolean.
977 * Changed _ALL_ unsigned long and unsigned int to uint32,
978 unsgined short to uint16 in the source tree.
980 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
981 not handle clients that has entry->data.registered == FALSE.
982 They are not in the network anymore. Affected file is
985 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Implemented the sending of the SERVER_SIGNOFF notify in the
988 server. Affected file is silcd/server.c.
990 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
991 Added also silc_notify_payload_encode_args into the
992 lib/silccore/silcnotify.[ch].
994 * Implemented ther SERVER_SIGNOFF notify handling in the server.
995 Affected file silcd/packet_receive.c.
997 * Implemented the SERVER_SIGNOFF notify handling in the client
998 library. Affected file lib/silcclient/client_notify.c. Also,
999 implemnted the printing of the SERVER_SIGNOFF info to the
1000 application. Affected file silc/client_ops.c.
1002 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1003 if the deleting was successful. Affected file silcd/idlist.[ch].
1005 * Added support for public key authentication in the connection
1006 authentication protocol in the client library. Affected file
1007 lib/silcclient/protocol.c.
1009 * Changed the server's silc_idlist_get_clients_by_* interface
1010 to support already allocated array so that new entries may be
1011 added to pre-allocated array. Affected file silcd/idlist.[ch].
1012 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1013 and command replies.
1015 * All command reply functions in the server now calls the
1016 pending command callback even if error occured. This way the
1017 error will be delivered to the client as well. Affected files
1018 silcd/command.c and silcd/command_reply.c.
1020 * Fixed INFO command to return local server's info if no server
1021 was provided. Affected file lib/silcclient/command.c.
1023 * Removed RESTART command for good. Updated the code and the
1026 * Rewrote parts of the task system. It is a bit simpler now.
1027 Removed unsued task priorities. The affected files are
1028 lib/silcutil/silctask.[ch].
1030 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1032 * Moved the USERS printing from the library to the application.
1033 Affected files lib/silcclient/command.c and silc/client_ops.c.
1035 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1039 * Added channel key re-key support. The re-key is perfomed
1040 only by the router and is done once in an hour. Added `rekey'
1041 field to the SilcChannelEntry in the server. Affected files
1042 silcd/server.c and silcd/idlist.h.
1044 * Added silc_task_unregister_by_context into the file
1045 lib/silcutil/silctask.[ch].
1047 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1049 * Added SILC_UMODE_GONE mode to indicate when the client is not
1050 present in the SILC network. Added also support to the local
1051 command AWAY that will set this mode. Added support of showing
1052 "xxx is gone" in WHOIS command. The USERS command shows the
1053 gone status as well.
1055 * Fixed setting server and router operator privileges in the
1056 server's UMODE command. Affected file silcd/command.c.
1058 * Merged the SKE KE1 and KE2 payloads into one payload. The
1059 new KE payload is equivalent to the old KE2 payload.
1061 Cleaned up the SKE Start Payload parsing. It now uses the
1062 simple buffer unformatting to do the parsing. A lot faster
1065 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1066 to the SKE that is used to indicate whether both of the SKE
1067 parties should perform authentication. By default only the
1068 responder performs authentication. By setting this flag also
1069 the initiator must do authentication. By default it is unset
1070 since in normal SKE case, client to server connection, only
1071 the responder should do authentication. When doing SKE between
1072 two clients both should perform authentication. Updated the
1073 code and the protocol specs.
1075 * A little fix to IDENTIFY command in the server. Search the
1076 client first by hash not nickname. Affected file is
1079 * Fixed the silc_client_close_connection to support closing
1080 the client to client connections wihtout deleting too much
1081 data. Affected file lib/silcclient/client.c.
1083 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1084 are received if protocol used to be active but is not anymore
1085 the application would crash due to NULL pointer dereference.
1086 Affected files silcd/server.c and lib/silcclient/client.c.
1088 * Added `hash' field to the SilcClientConnection to include
1089 the hash function negotiated in the SKE protocol.
1091 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1092 to set the channel founder authentication data. A client can
1093 claim the founder rights later by providing the authentication
1094 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1095 This way the channel founder can regain the channel founder
1096 privileges even it is left the channel. This works only on
1097 local server and the client must be connected to the same
1098 server to be able to regain the founder rights. Updated the
1099 protocol specs accordingly.
1101 Added support to the CMODE command in the client to set the
1102 founder auth data. Read the README to see how to set it.
1104 Added support to the CUMODE command to claim the founder
1105 rights. Read the README to see how to do it.
1107 Added support for the founder authentication to the Channel
1108 Entry in the server. Affected file silcd/idlist.h.
1110 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1111 server's CMODE command. Affected file silcd/command.c.
1113 * Added the following new functions into lib/silccore/silcauth.[ch]:
1114 silc_auth_get_method and silc_auth_get_data.
1116 * The server now saves the remote hosts public key to the
1117 SilcIDListData pointer. Affected file silcd/protocol.c.
1119 * The normal server now does not remove the channel entry from
1120 the cache if the founder authentication data is set. It used
1121 to remove it if the founder was the last one on the channel on
1122 the server and left the channel. The auth data is saved and
1123 if the channel is re-joined later the old entry is used with
1124 the old auth data. Affected files silcd/command_reply.c and
1127 * Removed the `pkcs' field from the SilcIDListData structure
1128 in the server; it is not used. Affected file silcd/idlist.h.
1130 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1132 * Fixed packet processing on slow links. Partial packets were
1133 never re-processed because the incoming data buffer was cleared
1134 by the application. Application must not directly clear the
1135 sock->inbuf, the packet processing routines handle it. Fixed
1136 this in client library and in server.
1138 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1140 * Fixed the WHOIS and IDENTIFY send reply function to really
1141 check whether to send list or just one entry. Affected file
1144 * Cleaned up the LEAVE command's channel key distribution. The
1145 affected file silcd/command.c.
1147 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1148 can enforce the channel mode as well. In that case the ID
1149 includes the ID of the server. The code now enforces the
1150 mode change if the router have different mode than the server.
1152 * The notify client operation with CMODE_CHANGE notify can now
1153 return NULL client_entry pointer if the CMODE was not changed
1154 by client. Application must check for this.
1156 * Added <Server ID> argument to INFO command to support server
1157 info fetching by Server ID.
1159 * Added silc_server_announce_get_channel_users to get assembled
1160 packets of channel users of the specified channel. Affected
1161 file silcd/server.[ch].
1163 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1164 was freed underneath the ID Cache.
1166 * Re-announce clients when the server received CHANNEL_CHANGE
1167 notify from the router. Affected file silcd/packet_send.c.
1169 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1171 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1172 crashed since it did not handle the fact that there is no cipher
1173 called "3" and didn't check the error condition. Now fixed.
1175 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1176 flag. It can be used to send message requests.
1178 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1180 * Implemented the RESTART command in the client.
1182 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1183 notice type messages. Added notice printing to the user
1186 * The channel keys are not re-generated if the channel's mode
1187 is PRIVKEY, ie private key on the channel exists. Affected
1188 files silcd/server.c and silcd/command.c.
1190 * Fixed a little bug in channel message delivery when channel
1191 private keys are set in the server. Affected file is
1192 silcd/packet_send.c.
1194 * Changed the setting on channel->on_channel = TRUE from the
1195 silc_client_save_channel_key to the JOIN command reply. The
1196 key payload is not received if the private channel key is set.
1197 Affected file lib/silcclient/command_reply.c and the
1198 lib/silcclient/client_channel.c.
1200 * When the CMODE_CHANGE notify is sent and the channel private
1201 key mode is removed the channel key must be re-generated in
1202 other cells as well. Added this support for the router in the
1203 silcd/packet_receive.c.
1205 * Added new local command NOTICE to send notice message on
1206 channel. Affected file silc/local_command.[ch].
1208 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1210 * Added new local command ME to the client. It is used to send
1211 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1212 some action. Affected file silc/local_command.[ch].
1214 * Changed channel_message and private_message client operations
1215 to deliver the message flags to the application. Added also
1216 the `flags' arguments to the silc_client_send_channel_message
1217 and silc_client_send_private_message functions. Affected file
1220 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1222 * Redefined the Private Message Payload to support private message
1223 keys and to support the new private message flags. Updated
1224 the protocol specs. Flags makes it possible to have for example
1225 CTCP style messages.
1227 * Added new type SilcPrivateMessagePayload and defined an API
1228 for it in the lib/silcclient/silcprivate.[ch].
1230 * Tested private message private keys successfully. Tested the
1231 private message key set, unset and list commands with the new
1234 * Redefined the Channel Message Payload to include the channel
1235 message flags (equal with private message flags) to support
1236 for example CTCP style messages.
1238 * Defined some of the message (for channel and private message)
1239 flags. Updated the protocol specs and added the flags to the
1240 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1242 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1244 * Added SilcKeyAgreementStatus type to the key agreement routines
1245 to indicate the current status and error if one occured.
1246 The status types are defined in the lib/silcclient/silcapi.h.
1248 * Added new local command KEY that is used to set and unset private
1249 keys for channels, set and unset private keys for private messages
1250 with remote clients and to send key agreement requests and
1251 negotiate the key agreement protocol with remote client. The
1252 key agreement is supported only to negotiate private message keys,
1253 it currently cannot be used to negotiate private keys for channels,
1254 as it is not convenient for that purpose.
1256 * Fixed a minor pending callback setting bug in the function
1257 silc_client_get_client_by_id_resolve, now the function works.
1258 Affected file lib/silcclient/idlist.c.
1260 * Added function silc_net_get_local_port to get local bound
1261 port by socket. Added to lib/silcutil/silcnet.[ch].
1263 * Added `sockets' and `sockets_count' fields to the SilcClient
1264 object. They hold the sockets of the listenning sockets in
1265 the client. Listenning sockets may be for example the key
1266 agreement server. Affected file lib/silcclient/client.[ch].
1267 Added functions the silc_client_add_socket and the
1268 silc_client_del_socket. They are exported to the application
1271 * Added ~./silc/clientkeys to support other client's public keys.
1273 * Renamed verify_server_key client operation to verify_public_key
1274 and added one argument to indicate the type of the connection
1275 (server, client etc.).
1277 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1279 * Added silc_server_connection_auth_request to handle the
1280 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1281 silcd/packet_receive.[ch].
1283 * Added silc_server_send_connection_auth_request into the
1284 silcd/packet_send.c to send the connection auth request packet.
1286 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1289 * Fixed the public key authentication in responder side in the
1290 server. The `auth_data' pointer includes the SilcPublicKey
1291 not the path to the public key. Affected file silcd/protocol.c.
1293 * Implemented the public key authentication in the initiator side
1294 in the server. Affected file silcd/protocol.c.
1296 * Removed the [RedirectClient] config section from the server
1297 configuration. Is not needed and I don't want to implement it.
1299 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1301 * Cleaned up the CMODE command in the server. It now works
1302 correctly and supports all the modes defined in the protocol.
1303 Affected file is silcd/command.c.
1305 * Added `hmac_name' field to the SilcChannelEntry in the server
1306 to hold the default HMAC of the channel. It can be set when
1307 creating the channel (with JOIN command). Affected files
1310 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1311 type to indicate the change of the current cipher and hmac
1312 on the channel. Client can safely ignore the <cipher> argument
1313 (if it chooses to do so) since the CHANNEL_KEY packet will
1314 force the channel key change anyway. The <hmac> argument is
1315 important since the client is responsible of setting the new
1316 HMAC and the hmac key into use.
1318 * Fixed the CMODE command in the client library as well.
1320 * Tested CMODE command in router environment successfully.
1322 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1324 * Show the version of the remote client (or server) when connecting
1325 to the server. It is logged to the log file. Affected file
1326 is silcd/protocol.c.
1328 * Fixed the KILLED notify handling in the client library. The
1329 client must be removed from all channels when receiving the
1332 Also, do not remove the client entry when giving the KILL
1333 command but when the KILLED notify is received.
1335 * Removed silc_idlist_find_client_by_nickname from the server.
1336 Not needed anymore. Affected files silcd/idlist.[ch].
1338 * Implemented the CHANNEL_CHANGE notify type handling to the
1339 server. Affected file silcd/server.c.
1343 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1345 * Added silc_server_send_notify_invite to send the INVITE
1346 notify between routers.
1348 * Implemented the INVITE command correctly to the server.
1350 * Implemented the INVITE notify type handling in the server.
1352 * Implemented the INVITE command to the client library and on the
1355 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1357 * Added function silc_server_get_client_resolve to find the
1358 client entry by ID from all ID lists and then resolve it
1359 (using WHOIS) if it cannot be found. Affected file is
1362 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1364 * Implemented the BAN command to the client library.
1366 * The JOIN command in the server now checks the invite list
1369 * Changed the silc_command_reply_payload_encode_va and the
1370 silc_command_payload_encode_va to support that if argument is
1371 NULL it ignores and checks the next argument. Affected file
1372 lib/silccore/silccommand.c.
1374 * Added silc_server_send_notify_ban to send the BAN notify
1375 type between routers.
1377 * Chaned the silc_notify_payload_encode to support that if
1378 argument is NULL it ignores and checks the next argument.
1379 Affected file lib/silccore/silcnotify.c.
1381 * Tested ban lists in router environment successfully.
1383 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * Implemented BAN command to the server, in silcd/command.[ch].
1387 * Removed the BAN and INVITE_LIST modes from the CMODE command
1390 * Added function silc_string_match to regex match two strings.
1391 Affected files lib/silcutil/silcutil.[ch].
1393 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1395 * Redefined parts of the SilcChannelEntry in the server to support
1396 the new ban and invite lists.
1398 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1400 * Redefined the INVITE command. The same command can be used to
1401 invite individuals to the channel but also to manage the invite
1402 list of the channel (to add to and remove from the invite list).
1403 Updated the protocol specs.
1405 * Added new command SILC_COMMAND_BAN that can be used to manage
1406 the ban list of the channel. Updated the protocol specs.
1408 * Removed the channel modes: the SILC_CMODE_BAN and the
1409 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1410 in the CMODE command. The equivalent features are now available
1411 using INVITE and BAN commands. Updated the protocol specs.
1413 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1414 in the network about change in the current ban list. The notify
1415 type is not used by the client.
1417 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1418 support the invite lists.
1420 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1422 * Added new function silc_string_regexify that converts string
1423 including wildcard characters into regex string that can
1424 be used by the GNU regex library. Added into the file
1425 lib/silcutil/silcutil.[ch].
1427 Added silc_string_regex_combine to combine to regex strings
1428 into one so that they can be used as one regex string by
1429 the GNU regex library. Added into the file
1430 lib/silcutil/silcutil.[ch].
1432 Added silc_string_regex_match to match two strings. It returns
1433 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1435 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1437 * Imported GNU regex to the soruce tree into lib/contrib.
1438 Fixed some compiler warning from the regex.c.
1440 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1442 * Fixed MOTD command in the server to work in router environment.
1444 * Fixed the MOTD command in the client library to support
1445 the server argument in the command.
1447 * Added `nickname_len' argument to the silc_idlist_add_client
1448 in the server, as the `nickname' argument may be binary data
1451 * Added silc_idlist_get_channels to return all channels from
1454 * Implemented LIST command to the server. Affected file is
1457 * Implemented the LIST command to the client library and on the
1460 * Added [<user count>] argument to the LIST command reply.
1461 With private channels the user count is not shown.
1463 * Updated TODO and README.
1465 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1467 * The client entry's data.registered must be TRUE even with
1468 global client entry on global client list. The data.registered
1469 is used to check whether the client is anymore in the network,
1470 for example with WHOWAS command so it must be valid.
1472 * Fixed the WHOWAS command in the server. It now actually works
1473 in router environment. Added function into silcd/command_reply.c
1474 silc_server_command_reply_whowas_save.
1476 * Added silc_idlist_purge function to the silcd/idlist.c
1477 to periodically purge the ID Cache.
1479 * Fixed INFO command in the server. It works now in router
1480 environment. Added <server name> argument to the INFO command
1481 reply. Updated the protocol specs.
1483 * Fixed minor bug in silc_idcache_purge to not purge if the
1484 expire value is zero.
1486 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1487 they were buggy because of the WHOWAS information.
1489 * Fixed local command MSG to handle the async resolving of
1490 the remote client properly. It used to fail the first MSG.
1491 Affected file silc/local_command.c.
1493 * Added `data_len' field to SilcIDCache context.
1495 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1497 * Update TODO. Todo in commands in the server.
1499 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1502 used by routers as broadcast packet to inform other routers
1503 about the changed user mode.
1505 Implemented the notify handling in the server. Affected file is
1506 silcd/packet_receive.c. Added the function
1507 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1509 * Added new generic Channel Payload and deprecated the New Channel
1510 Payload. The New Channel Payload is now the generic Channel
1513 * Added new argument `mode' to the silc_server_send_new_channel
1514 as it is required in the Channel Payload now.
1516 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1517 and created a new and real SilChannelPayload to represent the
1518 new generic Channel Payload. Implemented the encode/decode
1519 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1521 * Added silc_server_get_client_channel_list to return the list
1522 of channels the client has joined for WHOIS command reply.
1523 Affected file silcd/server.[ch].
1525 * Implemented the channel list sending in the WHOIS command reply
1526 in server and in the client.
1528 Implemented the channel list displaying on the user interface
1529 as well. Affected file silc/client_ops.c.
1531 * Added silc_channel_payload_parse_list to parse list of Channel
1532 Payloads. It returns SilcDList list of SilcChannelPayloads.
1533 Client for example can use this function to parse the list of
1534 channels it receives in the WHOIS command reply. The caller
1535 must free the list by calling silc_channel_payload_list_free.
1536 Affected files lib/silccore/silcchannel.[ch].
1538 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1540 * Added one new argument <user mode> to the WHOIS command reply
1541 to return the mode of the user in SILC. Updated the protocol
1544 Implemented it to the server and client.
1546 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1548 * Fixed the mode printing on the user interface on joining.
1549 Affected file silc/client_ops.c.
1551 * Implemented the UMODE command and user modes in general to the
1552 client library and to the user interface.
1554 * Implemented the UMODE command to the server.
1556 * The server now sends UNKNOWN_COMMAND error status if client sends
1557 unknown command. Affected file silcd/command.c.
1559 * All server commands now handle the command identifier the right
1560 way when sending the command reply to the client. The client can
1561 use to identify the command replies with the identifier.
1563 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1565 * Added silc_server_get_client_route to resolve the route to
1566 the client indicated by the client ID. Affected file is
1569 * Added silc_server_relay_packet as general function to relay
1570 packet to arbitrary destination. This deprecates functions
1571 like _send_private_message_key, _relay_notify etc. Affected
1572 file is silcd/packet_send.[ch].
1574 Removed silc_server_send_key_agreement,
1575 silc_server_send_private_message_key and
1576 silc_server_packet_relay_notify functions from the file
1577 silcd/packet_send.[ch].
1581 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1582 server. Affected file silcd/packet_receive.[ch].
1584 * Implemented the KILL command to the client. Implemented the
1585 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1586 Affected files lib/silcclient/command[_reply].c and
1587 lib/silcclient/client_notify.c. Implemented the KILL notify
1588 printing in the user inteface.
1590 * Fixed a lot silc_parse_nick memory leaks from the client
1591 library in the file lib/silcclient/command.c.
1593 * Changed the silc_server_send_notify_on_channels's `sender'
1594 argument from SilcSocketConnection to SilcClientEntry to
1595 check the sender as entry and not as connection object and not
1596 to send to the client provided as argument. The affected file
1597 is silcd/packet_send.[ch].
1599 * The notify packets that are destined directly to the client used
1600 to not to be processed by the server. Now changed that and the
1601 server processes all notify packets. After relaying the packet
1602 to the client the notify packet is processed in the server.
1604 * The silc_server_free_client_data now checks whether there is
1605 pending outgoing traffic for the client and purges the data to
1606 the network before removing the client entry.
1608 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1611 an client is killed from the SILC Network. Updated the protocol
1614 Added new function silc_server_send_notify_killed to the
1615 silcd/packet_send.[ch].
1617 * Added function silc_server_packet_relay_notify to relay notify
1618 packets that are destined directly to a client. In this case
1619 the server does not process the notify packets but merely relays
1620 it to the client. Affected file silcd/packet_send.[ch].
1622 Added also silc_server_packet_process_relay_notify to check
1623 whereto relay the notify. Affected file is
1624 silcd/packet_receive.[ch].
1626 * Implemented the KILL command to the server.
1630 * Added the backup schema desgined last fall to the protocol
1631 specs for everyone to see. The specification is in the
1632 *-spec-xx.txt draft and the packet type definitions for the
1633 backup routers is in *-pp-xx.txt draft. Thusly, added also
1634 new packet type SILC_PACKET_CELL_ROUTERS.
1636 * A big security problem in the implementation discovered. The
1637 signoff of an client did not cause new channel key generation
1638 which it of course should've done. The channel keys must be
1639 always re-generated when client leaves (or signoffs) the channel.
1640 The silc_server_remove_from_channels funtion now handles
1641 the channel key re-generation.
1643 * Added `sender' argument to the silc_server_send_notify_on_channels
1644 to not to send the client provided as argument. Affected file
1645 silcd/packet_send.[ch].
1647 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1649 * Implemented OPER and SILCOPER commands into the server and
1652 * Added silc_auth_verify and silc_auth_verify_data to verify
1653 the authentication directly from the authentication payload.
1654 It supports verifying both passphrase and public key based
1655 authentication. Affected file lib/silccore/silcauth.[ch].
1657 * Added `hash' field to the SilcIDListData structure. It is the
1658 hash negotiated in the SKE protocol. Affected file is
1661 * Slight redesigning of the SilcAuthPayload handling routines.
1662 Do not send SilcPKCS but SilcPublicKey as argument.
1664 * Implemented the public key authentication support to the
1665 serverconfig. The public key is loaded from the provided path
1666 and saved as authentication data to void * pointer. Thus,
1667 changed the unsigned char *auth_data to void *auth_data;
1669 * Fixed SHUTDOWN command to send the reply before the server
1670 is shutdown. :) Affected file silcd/command.c.
1672 * Fixed fatal bug in CONNECT command. The hostname was invalid
1673 memory and server crashed. Affected file silcd/command.c.
1675 * Fixed fatal bug in CLOSE command. The server_entry became
1676 invalid but was referenced later in the command. Affected file
1679 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1681 * Fixed fatal bug in failure packet handling. Server ignored
1682 the failure and thus crashed when it came.
1686 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1688 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1689 that the command may be executed only once in (about) 2 seconds.
1690 The old SILC_CF_LAG flag is same but allows command bursts up
1691 to five before limiting.
1693 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1694 server code. Various commands now includes the CF_LAG_STRICT
1695 flag to disallow any kind of miss-use of the command.
1697 * Fixed the silc_buffer_unformat to not to allocate any data
1698 if the length of the data is zero. It used to allocate the
1699 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1701 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1703 * Changed the format of AdminConnection configuration section
1704 in the server. Added username of the admin to the format.
1705 Affected files silcd/serverconfig.[ch].
1707 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1708 to return admin configuration data by host, username and/or
1711 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1713 * Implemented WHOWAS command to the server. Added the functions:
1715 silc_server_command_whowas_parse,
1716 silc_server_command_whowas_send_reply,
1717 silc_server_command_whowas_from_client and
1718 silc_server_command_whowas_from_server
1720 * Added <Client ID> argument to the WHOWAS command reply. Updated
1721 the protocol specs accordingly.
1723 * Implemented WHOWAS command and command_reply to the client
1726 Implemented the WHOWAS printing on the user interface.
1728 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1730 * Added new argument to the WHOWAS command reply, the real name.
1731 It is an optional argument. Updated the protocol specs.
1733 * Added SilcIDCacheDestructor callback that is registered when
1734 the SilcIDCache is allocated. The callback is called when
1735 an cache entry in the ID Cache expires, or is purged from the
1736 cache. Added into lib/silccore/idcache.[ch].
1738 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1739 to destruct the client entries when the cache entry expires.
1740 Other ID Cache's in server and in the client library ignores
1743 * If the ID Cache entry's `expire' field is zero then the entry
1744 never expires. Added boolean `expire' argument to the
1745 silc_idcache_add function in the lib/silccore/idcache.[ch].
1746 If it is TRUE the default expiry value is used.
1748 * Added silc_server_free_client_data_timeout that is registered
1749 when client disconnects. By default for 5 minutes we preserve
1750 the client entry for history - for WHOWAS command.
1752 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1754 * Added support to the server to enforce that commands are not
1755 executed more than once in 2 seconds. If server receives
1756 commands from client more frequently, timeout is registered
1757 to process the commands. Affected file silcd/command.c.
1758 Added new function silc_server_command_process_timeout.
1760 * Changed NICK_NOTIFY handling in client library to check that
1761 if the client's nickname was changed, so there is no need to
1762 resolve anything from the server.
1764 * Removed error printing from the WHOIS and IDENTIFY commands.
1765 If error occurs then it is ignored silently in the client library.
1766 The application, however, may map the received error to
1767 human readable error string. The application currently maps
1768 the NO_SUCH_NICKNAME error to string.
1770 * Made the command status message public to the application. Moved
1771 them from lib/silcclient/command_reply.c to
1772 lib/silcclient/command_reply.h. The application can map the
1773 received command status to the string with the
1774 silc_client_command_status_message function.
1776 * Added check to the server to check that client's ID is same
1777 as the Source ID in the packet the client sent. They must
1780 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1782 * Added dist-bzip hook to the Makefile.am to make bzip2
1783 compressed distributions.
1785 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1787 * Server now enforces the maximum length for the nickname and
1788 the channel as protocol specification dictates. 128 bytes for
1789 nickname and 256 bytes for channel name.
1791 * Moved the WHOIS printing to the application. The client libary
1792 does not print out the WHOIS information anymore, the application
1793 must do it. Renamed silc_client_command_reply_whois_print to
1794 the silc_client_command_reply_whois_save.
1796 The client's idle time is also sent to the application now, and
1797 the idle is shown on screen.
1799 * Added silc_client_command_reply_identify_save to save the
1800 received IDENTIFY entries.
1802 * Do not check for channel private keys in message sending and
1803 reception if the channel does not have the PRIVKEY mode set.
1804 Affected file lib/silclient/client_channel.c.
1806 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1808 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1809 just surfaced after chaning the JOIN procedure.
1811 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1813 * Added silc_client_get_clients_by_list to get client entries
1814 from Client ID list, that is returned for example by JOIN
1815 and USERS command replies. The application should use this
1816 function for example when JOIN command reply is received to
1817 resolve the clients already on the channel (library does not
1818 do that anymore as USERS command reply is not used in the JOIN
1819 procedure anymore). Affected files lib/silcclient/silcapi.h and
1820 lib/silcclient/idlist.c.
1822 * JOIN command reply and USERS command reply returns now SilcBuffer
1823 pointers instead of unsigned char pointers when returning
1824 the client list and mode list.
1826 * Added <Client ID> argument to the JOIN command reply, mainly
1827 for the server to identify for which client the command was
1828 originally sent. Updated protocol specs accordingly.
1830 * Added SilcDlist private_key pointer to the SilcChannelEntry
1831 in the client to support the channel private keys. Affected
1832 file is lib/silcclient/idlist.h.
1834 * Added SilcChannelPrivateKey argument to the function
1835 silc_client_send_channel_message so that application can choose
1836 to use specific private ke if it wants to. If it is not provided,
1837 the normal channel key is used, unless private keys are set.
1838 In this case the first (key that was added first) is used
1839 as the encryption key.
1841 * Implemented the support for channel private key handling.
1842 Implemented the following functions:
1844 silc_client_add_channel_private_key,
1845 silc_client_del_channel_private_keys,
1846 silc_client_del_channel_private_key,
1847 silc_client_list_channel_private_keys and
1848 silc_client_free_channel_private_keys
1850 Affected file lib/silcclient/client_channel.c.
1852 * Added the support for the private keys in the channel message
1853 sending and encryption and in the message reception and
1854 decryption. Affected funtions are
1855 silc_client_send_channel_message and silc_client_channel_message.
1857 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * Added SKE's key verify callback to the client library's
1860 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1862 * Removed the statement that server (or router) must send USERS
1863 command reply when joining to the channel so that the client
1864 knows who are on the channel. Instead, the client list and
1865 client's mode list is now sent in the JOIN command reply to the
1866 client who joined channel. This is better solution.
1868 * Added function silc_server_get_users_on_channel and function
1869 silc_server_save_users_on_channel to the silcd/server.[ch].
1871 * Removed function silc_server_command_send_users from the
1874 * Do not show topic on the client library anymore. The topic is
1875 sent in the command reply notify to the application and the
1876 application must show the topic now.
1878 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * Added client searching by nickname hash into the IDENTIFY and
1881 WHOIS commands in the server as they were clearly missing from
1882 them. Affected file is silcd/command.c.
1884 * Fixed a bug in private message receiving in the client library.
1885 The remote ID was freed and it wasn't supposed, now it is
1888 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Minor fix to the channel payload; allocate the data area, as it
1891 needs to be of specific length.
1893 * If the key agreement port is zero then the operating
1894 system will define the bound port. Affected files are
1895 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1897 * Added new function silc_channel_payload_decrypt into the file
1898 lib/silccore/silcchannel.[ch].
1900 * Moved the channel message etc, check from silc_packet_decrypt
1901 to applications. The library calls now a generic
1902 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1903 when the packet is either normal or special. This was done to
1904 allow more wide range of checking that was not allowed when
1905 the code was in library. Now applications can do virtually any
1906 checks to the packet and return to the library the decision how
1907 the packet should be processed. Affected files are
1908 lib/silccore/silcpacket.[ch].
1910 Added silc_server_packet_decrypt_check to the server and
1911 silc_client_packet_decrypt_check to the client library.
1913 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1914 to send with specified source and destination information.
1916 * Channel message delivery between routers was broken after the
1917 channel key distribution was fixed earlier. The channel key
1918 was used be to distributed to other routers as well which is not
1919 allowed by the protocol. Now this is fixed and channel keys
1920 really are cell specific and the channel message delivery between
1921 routers comply with the protocol specification.
1923 * Fixed various commands in server to check also the global list
1924 for the channel entry and not just the local list. The affected
1925 file silcd/command.c.
1927 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1929 * Added assert()s to buffer formatting and unformatting routines
1930 to assert (if --enable-debug) when error occurs. Affected
1931 file: lib/silcutil/silcbuffmt.c.
1933 * Changed to auto-reconnect to check whether the remote host is
1934 router and register the re-connect timeout if it is. It used
1935 to check that whether we are normal server, but router must do
1936 auto-reconnect with another router as well. Affected file
1939 * Removed the [<key len>] option from CMODE command as the cipher
1940 name decides the key length, nowadays. See the defined ciphers
1941 from the protocol specification.
1943 * Added [<hmac>] option to the CMODE command to define the HMAC
1944 for the channel. Added SILC_CMODE_HMAC channel mode.
1946 * Added [<hmac>] option for the JOIN command so that user can
1947 select which HMAC is used to compute the MACs of the channel
1950 * Added Hmac field to the Channel Message Payload. The integrity
1951 of plaintext channel messages are now protected by computing
1952 MAC of the message and attaching the MAC to the payload. The
1953 MAC is encrypted. Now, it is clear that this causes some
1954 overhead to the size of the packet but rationale for this is that
1955 now the receiver can verify whether the channel message decrypted
1956 correctly and also when private keys are set for the channel the
1957 receiver can decrypt the packet with several keys and check from
1958 the MAC which key decrypted the message correctly.
1960 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1961 lib/silccrypt/silccipher.[ch].
1963 * Added silc_hash_len to return the digest length into the
1964 lib/silcrypt/silchash.[ch].
1966 * Rewrote parts of Silc Channel Payload interface in the
1967 lib/silccore/silcchannel.[ch]. The encode function now also
1968 encrypts the packet and parse function decrypts it.
1970 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1972 * Fixed a minor formatting bug in the SKE's key material processing.
1973 It actually might have processed the keys wrong way resulting
1976 * Redefined the mandatory HMAC algorithms and added new algorithms.
1977 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1978 and hmac-md5 truncated to 96 bits. The mandatory is now
1979 hmac-sha1-96. Rest are optional (including the one that used
1980 to be mandatory). Rationale for this is that the truncated HMAC
1981 length is sufficient from security point of view and can actually
1982 make the attack against the HMAC harder. Also, the truncated
1983 HMAC causes less overhead to the packets. See the RFC2104 for
1986 * Added new [hmac] configuration section. The SKE used to use
1987 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1988 is of course wrong. The official names that must be proposed in
1989 the SKE are the ones defined in the protocol specification
1990 (hmac-sha1-96 for example). The user can configure any hmac
1991 using any hash function configured in the [hash] section. At
1992 least, the mandatory must be configured.
1994 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1996 * Added HMAC list to the SKE proposal list. It has now both
1997 hash algorithm list and HMAC list. This makes the protocol
1998 incompatible with previous versions. The SKE now seems to work
1999 the way it is supposed to work, for the first time actually.
2001 * Defined plain Hash algorithms to the protocol specification.
2004 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2006 * Implemented support for key agreement packets into the server.
2007 Added functions silc_server_key_agreement and
2008 silc_server_send_key_agreement. Other than these functions,
2009 server has nothing to do with this packet.
2011 * Added support for private message key packets into the server.
2012 Added functions silc_server_private_message_key and
2013 silc_server_send_private_message_key.
2017 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2018 called in the protocol's final callback instead in the END
2019 protocol state. This makes a little more sense and in the same
2020 time in client we can use the same protocol routines for normal
2021 key exchange and to key agreement packet handling as well.
2023 * Added to both client's and server's KE protocol context the
2024 SilcSKEKeyMaterial pointer to save the key material. We will
2025 bring the key material to the protocol's final callback by doing
2026 this. The final callback must free the key material.
2028 * Added SKE's packet_send callback into client's KE protocol
2029 context so that the caller can choose what packet sending function
2030 is used. This way we can use different packet sending when
2031 doing normal SKE when doing key agreement packet handling (in
2032 the key agreement packet handling we do not want to encrypt
2035 * Implemented the responder side of the key agreement routines
2036 in the client. The client can now bind to specified port and
2037 accept incoming key negotiation. The key material is passed
2038 to the application after the protocol is over.
2040 * Implemented the processing of incoming Key Agreement packet
2041 in the client. Added function silc_client_key_agreement to
2044 * Implemented the intiator side of the key agreement routines
2045 in the client. The client can now initiate key agreement with
2046 another remote client. The key material is passed to the
2047 application after the protocol is over.
2049 * Created client_keyagr.c to include all the key agreement
2052 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2053 SILC_TASK_CALLBACK except that it is not static.
2055 * Created client_notify.c and moved the Notify packet handling
2056 from the client.[ch] into that file.
2058 * Created client_prvmsg.c and moved all private message and
2059 private message key routines from the client.[ch] into that file.
2061 * Create client_channel.c and moved all channel message and
2062 channel private key routines from the client.[ch] into that file.
2064 * Changed silc_client_get_client_by_id_resolve to resolve with
2065 WHOIS command instead of IDENTIFY command, in the file
2066 lib/silclient/idlist.c.
2068 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2070 * Implemented the SKE's responder side to the Client library.
2072 * When FAILURE is received to the protocol do not trust it
2073 blindly. Register a timeout to wait whether the remote closes
2074 the connection as it should do it, only after that process the
2075 actual failure. This was changed to both client and server.
2077 * Added client_internal.h to include some of the structures
2078 there instead of client.h in lib/silcclient/.
2080 * Added function silc_task_unregister_by_callback to unregister
2081 timeouts by the callback function.
2083 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * Some "Incomplete WHOIS info" errors has been appearing on the
2086 log files. Took away the entry->userinfo check from WHOIS
2087 reply sending. The entry->userinfo is now " " if client did not
2088 provide one. I thought this was fixed earlier but something
2089 is wrong still. Let's see if the error still appears.
2091 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2093 * Fixed a minor bug in the login when the channel key is
2094 re-generated in the server. It used to generate the key in
2095 wrong order and thus caused problems in the channel traffic.
2097 * Fixed a minor bug in channel key distsribution after
2098 KICK command. The key was not sent to the router even though
2101 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Added silc_ske_process_key_material_data as generic routine
2104 to process any key material as the SILC protocol dictates. The
2105 function is used by the actual SKE library but can be used by
2106 applications as well. This relates to the private message keys
2107 and the channel private keys since they must be processed the
2108 same way the normal SILC session keys. The protocol dictates
2109 this. Affected files: lib/silcske/silcske.[ch].
2111 Added also silc_ske_free_key_material to free the
2112 SilcSKEKeyMaterial structure.
2114 * Defined silc_cipher_set_key function to set the key for
2115 cipher without using the object's method function. The affected
2116 files: lib/silccrypt/silccipher.[ch].
2118 * Implemented silc silc_client_add_private_message_key,
2119 silc_client_add_private_message_key_ske,
2120 silc_client_del_private_message_key,
2121 silc_client_list_private_message_keys and
2122 silc_client_free_private_message_keys functions in the
2125 Added functions silc_client_send_private_message_key to send
2126 the Private Message Key payload and silc_client_private_message_key
2127 to handle incoming Private Message Key payload.
2129 * Added Cipher field to the Private Message Key payload to set
2130 the cipher to be used. If ignored, the default cipher defined
2131 in the SILC protocol (aes-256-cbc) is used.
2133 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Removed lib/silcclient/ops.h file.
2137 Redefined parts of the SILC Client Library API. Created new
2138 file silcapi.h that deprecates the ops.h file and defines the
2139 published Client Library API. Defined also private message key
2140 API and channel private key API into the file.
2142 This is the file that the application must include from the
2143 SILC Client Library. Other files need not be included by
2144 the application anymore.
2146 * Added new key_agreement client operation callback and also
2147 defined the Key Agreement library API for the application.
2149 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2151 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2152 is used by clients to request key negotiation between another
2153 client in the SILC network. If the negotiation is started it
2154 is performed using the SKE protocol. The result of the
2155 negotiation, the secret key material, can be used for example
2156 as private message key.
2158 Implemented the Key Agreement payload into the files
2159 lib/silccore/silauth.[ch].
2161 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2163 * Redefined ciphers for the SILC protocol. Added some new ciphers
2164 and defined the key lengths for the algorithms. Changed the
2165 code accordingly. The default key length is now 256 bits.
2167 * Fixed SKE key distribution function silc_ske_process_key_material
2168 when the key length is more than 128 bits. The default key
2169 length in SILC is now 256 bits.
2171 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2172 to indicate unsupported algorithm.
2174 * Renamed rijndael.c to aes.c and all functions as well.
2176 * Fixed a long standing channel key setting bug in client library.
2177 Weird that it has never surfaced before.
2179 * Fixed bug in channel deletion. If the entire channel is removed
2180 then it must also delete the references of the channel entry
2181 from the client's channel list as the client's channel entry and
2182 the channel's client entry share same memory.
2184 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2186 * Implemented CONNECT and SHUTDOWN commands in the client.
2188 * Implemented CLOSE command to the client.
2190 * Added the function silc_idlist_find_server_by_name into the
2191 files silcd/idlist.[ch].
2193 Added the function silc_idlist_find_server_by_conn into the
2194 files silcd/idlist.[ch].
2196 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2198 * DIE command was renamed to SHUTDOWN. Updated the both code
2201 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2202 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2204 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2207 * Added function silc_server_create_connection function to create
2208 connection to remote router. My server implementation actually
2209 does not allow router to connect to normal server (it expects
2210 that normal server always initiates the connection to the router)
2211 so the CONNECT command is only good for connecting to another
2214 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2216 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2217 or some other client was kicked from the channel.
2219 Implemented the handling of the notify type to both client
2222 Implemented silc_server_send_notify_kicked to send the KICKED
2223 notify. It is used to send it to the server's primary router.
2225 * Implemented the KICK command into server and client.
2227 * Added `query' argument to the silc_idlist_get_client function
2228 to indicate whether to query the client from server or not if
2231 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2232 to indicate that the client is not channel founder.
2236 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2238 * Removed the rng context from SilcPacketContext structure and
2239 changed that the packet routine uses the Global RNG API.
2241 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * Added support for quit message that client can "leave" on the
2244 channel when it quits the SILC. It is ditributed inside the
2245 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2247 Added silc_server_free_client_data that will take the
2248 signoff message as argument.
2250 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2252 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2254 * Updated parts of the protocol specification to keep it up
2257 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2259 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2260 payloads in one packet.
2262 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2263 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2264 use now the new List flag.
2266 * Also deprecated the following packet types: REPLACE_ID,
2267 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2269 * Added list support for Notify packet in server.
2271 * Added silc_server_send_notify_channel_change to send the
2272 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2273 the silc_server_send_replace_id.
2275 * Added silc_server_send_notify_nick_change to send the
2276 NICK_CHANGE notify type. Deprecates the function
2277 silc_server_send_replace_id.
2279 * Added silc_server_send_notify_join to send the JOIN notify type.
2280 Deprecates the function silc_server_send_new_channel_user.
2282 * Added silc_server_send_notify_leave to send LEAVE notify type.
2283 Deprecates the function silc_server_send_remove_channel_user.
2285 * Added silc_server_send_notify_cmode and
2286 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2287 types. Deprecates the silc_server_send_set_mode function.
2289 * Added SERVER_SIGNOFF notify type to indicate that server has
2290 quit. This means that all clients on the channel from that
2291 server will drop. This can be also used when netsplit happens.
2293 Deprecated REMOVE_ID packet type since it is not needed anymore
2296 Added silc_server_send_notify_server_signoff to send the
2297 SERVER_SIGNOFF notify type. Deprecates the function
2298 silc_server_send_remove_id.
2300 Added also silc_server_send_notify_signoff to send the
2301 SIGNOFF notify type.
2303 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2304 SILC protocol from this day on. Changed the protocol
2305 specification as well.
2307 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2308 notify type. It is used between routers to notify about
2309 topic changes on a channel.
2311 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2314 * Partly updated the protocol specification to comply with the
2315 changes now made. It is still though a bit outdated.
2317 * The JOIN notify type now takes one extra argument <Channel ID>.
2318 The packet used to be destined to the channel but now the
2319 JOIN type may be sent as list thus it is impossible to
2320 destine it to any specific channel. By adding this argument
2321 it is again possible.
2323 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2325 * Added CREDITS file. The CHANGES and CREDITS file will appear
2326 in the distribution as well.
2328 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2330 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2331 types in the server's silcd/packet_receive.c.
2333 * Implemented CMODE and CUMODE to work in router environment.
2335 * Fixed minor encoding and decoding buglet from the
2336 lib/silccore/silcmode.c.
2338 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2341 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2343 * Changed all SilcConfigServer* and silc_config_server* to
2344 SilcServerConfig* and silc_server_config*, respectively.
2347 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2349 * Associated the ID (client or server ID) to the Authentication
2350 Payload to avoid any possibility of forging. Updated the
2351 protocol specification and the code accordingly.
2353 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2355 * The RSA key length is now save to the RsaKey context in the
2356 key generation process in lib/silccrypt/rsa.c. The key length
2357 is now used to figure out the maximum size of the block allowed
2358 to be encrypted/signed.
2360 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2361 is equivalent to the silc_mp_mp2bin but does not allocate any
2364 * Changed silc_mp_mp2bin API to take length argument. If it is
2365 non-zero then the buffer is allocated that large. If zero, then
2366 the size is approximated using silc_mp_sizeinbase, which however
2369 * Created Global RNG API which is global RNG that application can
2370 initialize. After initializing, any routine anywhere in the
2371 code (including library) can use RNG without allocating a new
2372 RNG object. This was done to allow this sort of use of the
2373 RNG in code that has no chance to allocate RNG object. All
2374 applications currently allocate this and many routines in the
2375 library use this. Affected file lib/silccrypt/silcrng.[ch].
2377 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2378 it to use the Global RNG API.
2380 * Defined Authentication Payload into protocol specification that
2381 is used during SILC session to authenticate entities. It is
2382 used for example by client to authenticate itself to the server
2383 to obtain server operator privileges.
2385 Implemented this payload into the lib/silccore/silcauth.[ch].
2386 Implemented also routines for public key based authentication
2387 as the new protocol specification dictates.
2389 Moved definitions of different authentication methods from
2390 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2392 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2393 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2394 silc_pkcs_verify_with_hash functions into the file
2395 lib/silccrypt/silcpkcs.[ch].
2397 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2399 * The client entry's userinfo pointer must be always valid.
2400 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2401 will fail since it requires the userinfo. Now, the userinfo
2402 is allocated as "" if actual userinfo does not exist. Actually,
2403 it must exist and it is totally Ok to drop client connections
2404 that does not announce the userinfo. However, we will make
2405 this workaround for now.
2407 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2408 to return the remote port by socket.
2410 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2412 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2413 SILC_SERVER_PENDING_EXEC and added an new macro
2414 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2415 data or when error occurs while processing the pending command.
2417 Added new argument `destructor' into silc_server_command_pending
2418 and to the SilcServerCommandPending object. This destructor is
2419 now called after calling the pending callback or if error occurs
2420 immediately. If error occurs the actual pending callback won't
2421 be called at all - only the destructor. The destructor may be
2422 NULL if destructor is not needed.
2424 All this applies for client library code as well. Similar
2425 changes were made there as well for the pending commands.
2427 In the client, the application must now allocate the
2428 SilcClientCommandContext with the silc_client_command_alloc
2431 * Added reference counter to the SilcServerCommandContext. Added
2432 function silc_server_command_alloc and silc_server_command_dup
2435 Same type of functions added to the client library for the same
2438 * Removed the cmd_ident from IDListData away since it is now
2439 global for all connections. It is the command identifier used
2440 in command sending and with pending commands. The affected file
2443 * Added reference counter to the SilcSocketConnection objecet to
2444 indicate the usage count of the object. The object won't be
2445 freed untill the reference counter hits zero. Currently only
2446 server uses this, and client ignores it. The client must be
2447 set to use this too later. The affected files are
2448 lib/silccore/silcsockconn.[ch]. Added also the function
2449 silc_socket_dup to increase the reference counter.
2451 This was mainly added because it is possible that the socket
2452 is removed underneath of pending command or other async
2453 operation. Now it won't be free'd and proper DISCONNECTING
2454 flags, etc. can be set to avoid sending data to connection that
2455 is not valid anymore.
2457 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2458 the connection. After that it sets SILC_SET_DISCONNECTED.
2459 It is, however, possible that the socket data is not still freed.
2460 The silc_server_packet_process now checks that data is not
2461 read or written to connection that is DISCONNECTED. The socket
2462 get's freed when the reference counter hits zero.
2464 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Changed the client operation API: channel_message operation's
2467 `sender' is now the client entry of the sender, not the nickname
2468 and the `channel' is the channel entry, not the channel name.
2470 In the private_message operation the `sender' is now also the
2471 client entry of the sender not the nickname.
2473 Affected file is lib/silcclient/ops.h and all applications
2474 using the client operations.
2476 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Moved the calling of ops->connect() from connect_to_server_final
2479 into receive_new_id functin since that is the point when the
2480 client is actually allowed to send traffic to network. The
2481 affected file is lib/silcclient/client.c.
2483 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2486 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2487 (if needs broadcasting) instead of broadcasting the packets one
2488 by one which would make a burst in the network traffic.
2490 * Added `broadcast' argument to the functions in silcd/server.[ch]
2491 silc_server_create_new_channel[_with_id] to indicate whether
2492 to send New Channel packet to primary router.
2494 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2496 * Added new function into the silcd/server.[ch] files:
2497 silc_server_create_new_channel_with_id to create new channel with
2498 already existing Channel ID.
2500 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2501 lib/silccore/silcpacket.h. This packet is used t send list of
2502 Set Mode payloads inside one packet. Server uses this to set
2503 the modes for the channels and clients on those channels, that it
2504 announced to the router when it connected to it. The protocol
2505 specification has been updated accordingly.
2507 * The silc_server_new_channel did not handle the packet coming
2508 from normal server as it normally does not send that. However,
2509 when it announces its channels it does send it. Implemented
2510 the support for that.
2512 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2513 into the file lib/silccore/id.h.
2515 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2517 * Fixed memory leaks in the functions silc_idlist_del_client,
2518 silc_idlist_del_channel and silc_idlist_del_server in the file
2519 silcd/idlist.c. All of those leaked like a sieve.
2521 * Fixed some small memory leaks in the client's function
2522 silc_client_notify_by_server.
2524 * Added functions into silcd/server.c: silc_server_announce_clients,
2525 silc_server_announce_channels and silc_server_announce_server.
2526 These functions are used by normal and router server to announce
2527 to its primary router about clients, channels and servers (when
2528 router) that we own. This is done after we've connected to the
2531 These functions effectively implements the following packet types:
2532 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2533 and SILC_PACKET_NEW_ID_LIST.
2535 * Added new functions into the silcd/packet_receive.[ch]:
2536 silc_server_new_id_list, silc_server_new_channel_list and
2537 silc_server_new_channel_user_list to handle the incoming
2538 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2540 * Added support of changing Channel ID in the function
2541 silc_server_replace_id. If the server that announces a channel
2542 to the router already exists in the router (with same name but
2543 with different Channel ID), router is responsible to send
2544 Replace ID packet to the server and force the server to change
2545 the Channel ID to the one router has.
2547 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2548 client that the Channel ID has been changed by the router. The
2549 normal server sends this to the client. Client must start using
2550 the new Channel ID as the channel's ID.
2552 Implemented handling of this new type into lib/silcclient/client.c
2553 into the function silc_client_notify_by_server.
2555 * Added new function silc_idlist_replace_channel_id into the files
2556 silcd/idlist.[ch] to replace the Channel ID.
2558 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2560 * Call silc_server_command_identify_check always when processing
2561 the IDENTIFY command in silcd/command.c
2563 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2565 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2566 send keepalive packets. The packet can be sent by clients,
2567 servers and routers.
2569 Added function silc_socket_set_heartbeat into the file
2570 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2571 If not set, the heartbeat is not performed. The actual
2572 heartbeat is implemented in the low level socket connection
2573 library. However, application is responsible of actually
2576 Added silc_server_send_heartbeat to send the actual heartbeat
2577 packet into silcd/packet_send.[ch]. Server now performs
2578 keepalive with all connections.
2580 * Added silc_task_get_first function into lib/silcutil/silctask.c
2581 to return the timeout task with shortest timeout. There was a bug
2582 in task unregistration that caused problems. TODO has been
2583 updated to include that task system must be rewritten.
2585 * The client library will now resolve the client information when
2586 receiving JOIN notify from server for client that we know but
2587 have incomplete information.
2589 * Rewrote parts of silc_server_remove_from_channels and
2590 silc_server_remove_from_one_channel as they did not remove the
2591 channel in some circumstances even though they should've.
2593 * Encryption problem encountered in server:
2595 The LEAVE command used to send the Channel Key packet to the
2596 router immediately after generating it. However, the code
2597 had earlier sent Remove Channel user packet but not immediately,
2598 ie. it was put to queue. The order of packets in the router
2599 was that Channel Key packet was first and Remove Channel User
2600 packet was second, even though they were encrypted in the
2601 reverse order. For this reason, MAC check failed. Now, this
2602 is fixed by not sending the Channel Key packet immediately but
2603 putting it to queue. However, this is more fundamental problem:
2604 packets that are in queue should actually not be encrypted
2605 because packets that are sent immediately gets encrypted
2606 actually with wrong IV (and thus MAC check fails). So, packets
2607 that are in queue should be encrypted when they are sent to
2608 the wire and not when they put to the queue.
2610 However, the problem is that the current system has not been
2611 designed to work that way. Instead, the packet is encrypted
2612 as soon as possible and left to the queue. The queue is then
2613 just purged into wire. There won't be any fixes for this
2614 any time soon. So, the current semantic for packet sending
2617 o If you send packet to remote host and do not force the send
2618 (the packet will be in queue) then all subsequent packets to the
2619 same remote host must also be put to the queue. Only after the
2620 queue has been purged is it safe again to force the packet
2623 o If you send all packets immediately then it safe to send
2624 any of subsequent packets through the queue, however, after
2625 the first packet is put to queue then any subsequent packets
2626 must also be put to the queue.
2628 Follow these rules and everything works fine.
2630 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2632 * Added new function silc_server_remove_clients_by_server to
2633 remove all client entries from ID list when the server connection
2634 is lost. In this case it is also important to invalidate all
2635 client entires as they hold the invalid server entry. This
2636 fixes fatal bug when server has lost connection and will reconnect
2639 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2641 * Made some sanity checks to silc_server_daemonise like to check
2642 whether the requested user and group actually exists.
2644 * Added sanity check to SKE's silc_ske_responder_finish to check
2645 that the public and private key actually is valid.
2647 * Invalidate the client's nickname when receiving Replace ID
2648 packet and the Client ID is being replaced. This means that the
2649 server will query the nickname if someone needs it (client)
2652 * Sort the ID Cache in client library when the ID Cache data
2653 has changed (needs sorting).
2655 * Do not allow for SILC client to create several connections to
2656 several servers. The client does not support windows right now
2657 and generating multiple connections causes weird behaviour.
2659 Irssi-silc client does support windows and can handle several
2660 connections without problems, see: www.irssi.org and SILC plugin.
2662 * Fixed some places where client was added to the IDList. The
2663 rule of thumb is following (in order to get everything right):
2664 If the client is directly connected local client then the
2665 `connection' argument must be set and `router' argument must be
2666 NULL to silc_idlist_add_client function. If the client is not
2667 directly connected client then the `router' argument must
2668 bet set and the `connection' argument must be NULL to the
2669 silc_idlist_add_client function.
2671 * The funtion silc_server_packet_send_local_channel actually did
2672 not check whether the client was locally connected or not. It
2673 does that now. Fixed a bug related to LEAVE command.
2675 * Fixed Remove Channel User payload parsing bug in server's
2676 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2678 * The server's silc_server_save_channel_key now checks also the
2679 global ID list for the channel as it might not be in the local
2680 list. Fixed a bug related to LEAVE command.
2682 * Is this the end of the [<unknown>] buglet that has been lurking
2683 around for a long time? A little for loop fix in server's
2684 silc_server_command_whois_parse that is used by both IDENTIFY
2685 and WHOIS command. At least, this was a clear bug and a cause
2686 of one type of [<unknown>] buglet.
2688 * WHOIS and IDENTIFY commands call the function
2689 silc_server_command_[whois/identify]_check function even if
2690 we are not router server.
2692 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2694 * Added --with-gmp configuration option. If set the GMP
2695 is always compiled in the SILC source tree. If not set then
2696 it is checked whether the system has the GMP3 installed. If
2697 it has then the GMP won't be compiled (the system's headers
2698 and library is used), if it doesn't have it then the GMP is
2699 compiled in the SILC source tree.
2701 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2703 * Changed RSA private exponent generation to what PKCS #1
2704 suggests. We try to find the smallest possible d by doing
2705 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2706 not security fix but optimization.
2708 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2710 * Added new config entry [Identity] to fork the server and run
2711 it as specific user and group. A patch from Bostik.
2713 * Imported Dotconf configuration library into lib/dotconf.
2714 This will be used to create the SILC configuration files later.
2715 It will appear in the distsribution after this commit.
2717 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2719 * A big code auditing weekend happening. Auditing code for
2720 obvious mistakes, bugs and errors. Also, removing any code
2723 Removed files for being obsolete:
2725 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2726 inline in the file lib/silcutil/silcbuffer.h)
2728 o lib/silcutil/silcbufutil.c (the header has inline versions)
2730 Changed code to fix possible error conditions:
2732 o The buffer formatting routines now check that the destination
2733 buffer really has enough space to add the data. This applies for
2734 both buffer formatting and unformatting
2735 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2736 unformatting was changed to accomodate following rules:
2737 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2738 sent to the function while XXX_*STRING will not allocate or copy
2739 the data into the buffer. Instead it sets the pointer from the
2740 buffer into the pointer sent as argument (XXX_*STRING used to
2741 require that the pointer must be allocated already). This change
2742 makes this whole thing a bit more consistent and more optimized
2743 (note that the data returned in the unformatting with XXX_*STRING
2744 must not be freed now). The routines return now -1 on error.
2746 o Tried to find all code that use buffer_format and buffer_unformat
2747 and added return value checking to prevent formatting and
2748 especially unformatting errors and possible subsequent fatal
2751 o Changed ske->x and ske->KEY to mallocated pointers in
2752 lib/silcske/silcske.h. Fixed possible data and memory leak.
2754 o Added return value checking to all *_parse* functions. Fixed
2755 many memory leaks as well.
2757 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2758 so that buffer overflows would not happen. All code now also
2759 checks the return value as it can fail.
2761 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Added reconnection support to server if the normal server looses
2764 its connection to the router (for example if router is rebooted).
2765 The server performs normal reconnection strategy implemented
2766 to the server. Affected file silcd/server.c.
2768 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * Added new packet type SILC_PACKET_SET_MODE that is used to
2771 distribute the information about changed modes (for clients,
2772 channels and clients channel modes) to all routers in the
2773 network. Updated the protocol specification accordingly.
2775 Added functions into silcd/packet_send.c and
2776 silcd/packet_receive.c: silc_server_send_set_mode,
2777 silc_server_set_mode.
2779 Added new files silcmode.[ch] into lib/silccore that implements
2780 the encoding and decoding of Set Mode Payload. Added new type
2781 SilcSetModePayload. Moved the definitions of different modes
2782 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2784 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2786 * Oops, a little mistake in server's connection authentication
2787 protocol. The protocol is not ended with FAILURE but with
2788 SUCCESS if the authentication is Ok. :) Affected file is
2791 * Implemented NICK_CHANGE notify handling in server in the file
2792 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2793 the local clients on the channel. After the changing nickname
2794 in router environment snhould work and the [<unknown>] nickname
2795 should appear no more.
2797 The silc_server_replace_id function that receives the Replace ID
2798 payload now sends the NICK_CHANGE notify type also in the file
2799 silcd/packet_receive.c
2801 * Changed WHOIS and IDENTIFY command to support the maximum amount
2802 of arguments defined in protocol specs (3328 arguments). This
2803 fixed a bug that caused problems when there were more than three
2806 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2808 * Added extra parameter, command identifier, to the
2809 silc_client_send_command so that explicit command identifier
2812 Changed that ID list routines uses specific command identifier
2813 when sending WHOIS/IDENTIFY requests to the server so that they
2814 can be identified when the reply comes back.
2816 Affected files lib/silcclient/command.[ch],
2817 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2819 * Added `sender' argument to silc_server_packet_send_to_channel
2820 to indicaet the sender who originally sent the packet to us
2821 that we are now re-sending. Ignored if NULL. Affected file
2822 silcd/packet_send.[ch].
2824 * Added some server statistics support in silcd/server_internal.h
2825 SilcServerStatistics structure and around the server code. Also
2826 send some nice statistics information when client is connecting
2829 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Fixed channel ID decoding in server's JOIN command reply in
2832 silcd/command_reply.c
2834 * Fixed braodcasting of replace ID payload to not to send it if
2835 we are standalone server in silcd/packet_receive.c.
2837 * Fixed all channel message sending routines to not to send
2838 packets to clients that has router set, since they are routed
2839 separately in the same function earlier. Affects file
2840 silcd/packet_send.c and all channel packet sending functions.
2842 * In USERS reply, res_argv[i] are not allocated, the table
2843 is allocated. Thus changed that free the table, not its
2846 * In server's whois_check and identify_check if the client is
2847 locally connected do not send any WHOIS commands - they are not
2850 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Fixed some minor bugs in client when sending WHOIS command. The
2853 arguments was in wrong order.
2855 * Removed statis function add_to_channel from server in
2856 silcd/command.c that was previously used with the joining but
2859 * Tested USERS command in router environment successfully with two
2860 routers, two servers and two clients.
2862 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Reorganized the USERS command and command reply in client library
2865 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2866 When the command is given by user we register a pending command
2867 callback that will reprocess the command after the reply has been
2868 received from the server. When reprocessing the packet we then
2869 display the information. Thus, the USERS information is displayed
2870 now in the command callback instead of in the command reply
2871 callback. The processing of the command is same as previously
2872 when server has sent the command reply in the JOINing process.
2874 * Added to USERS command in silcd/command_reply.c to join the client,
2875 we didn't use to know about, to the channel after we've created
2876 a client entry for it. Also, for clienet we did know already still
2877 check whether it is on the channel or not and add it if not.
2879 * Removed silc_server_command_join_notify as the function and its
2882 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Changed the client's pending command handling to the same as the
2885 server's pending command handling. It is also now possible to
2886 execute command reply functions from other command reply
2887 function as the function callbacks for commands and command
2888 replies are one and same. The pending commands are not static
2889 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2890 in client connection context. Thus, pending commands are server
2891 connection specific as it is convenient.
2893 Changed the function silc_client_command_pending and
2894 silc_client_command_pending_del and added new function
2895 silc_client_command_pending_check. Removed the
2896 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2899 * Added cmd_ident, current command identifier, to the client
2900 connection context in lib/silcclient/client.h to keep track on
2901 command identifiers used in command sending. Client's command reply
2902 function handling now supports the mandatory command identifiers.
2904 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2905 funtions in client to fully support pending command callbacks.
2907 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2908 as one of the arguments to the application in the command reply
2911 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2912 before first releasing SILC but came back. Now it is removed again
2913 and should come back nomore. The FORWARDED flag was used only
2914 by the JOINing procedure by forwarding the command packet to router.
2915 Now, the JOINing procedure has been changed to more generic (due
2916 to various router environment issues) and FORWARDED is not needed
2917 anymore for anything. The protocol specification is yet to be
2920 Now, removed silc_server_packet_forward from server and the flag
2921 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2923 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Renamed NAMES command to USERS command. The NAMES was named that
2926 due to historical reasons. Now it is renamed. Also, rewrote
2927 parts of the USERS command. The nickname list is not sent anymore
2928 by the server. Only Client ID and mode lists are sent in the USERS
2929 command. Changed this also to the protocol specification.
2931 The client now resolves the names and stuff after it receives
2932 the USERS list from the server when joining to the channel.
2934 * WHOIS and IDENTIFY commands has been changed to support multiple
2935 Client ID's per command. One can now search for multiple users
2936 in the network by sending only one WHOIS or IDENTIFY command.
2937 Changed the code and the protocol specifications.
2939 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2940 uses silc_server_command_whois_parse to parse the request. */
2942 * If normal server, do not parse the WHOIS and IDENTIFY requests
2943 before sending it to the router. Saves some time.
2945 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2947 * Fixed JOIN command on client library. Wrong number of arguments
2948 used to crash the client.
2950 * Added silc_server_channel_has_global function to check whether
2951 channel has global users or not.
2953 * Added silc_server_channel_has_local function to check whether channel
2954 has locally connected clients on the channel.
2956 * The silc_server_remove_from_one_channel now checks whether the
2957 channel has global users or not after given client was removed from
2958 the channel. It also checks whether the channel has local clients
2959 on the channel anymore. If it does not have then the channel entry
2960 is removed as it is not needed anymore.
2962 * The silc_server_notify now checks on JOIN notify whether the joining
2963 client is one of locally connected or global. If it is global then
2964 the channel has now global users on the channel and that is marked
2965 to the channel entry. Also, it now saves the global client to
2966 global list who is joining and JOINs it to the channel. This is
2967 for normal server, that is.
2969 Changed silc_server_send_notify_on_channel,
2970 silc_server_packet_relay_to_channel and
2971 silc_server_packet_send_to_channel check if we are normal server
2972 and client has router set (ie. global client) do not send the
2973 message to that client, as it is already routed to our router.
2975 * Implemented LEAVE notify type handling in silc_server_notify
2978 * Tested LEAVE command in router environment successfully. Tested
2979 with two routers, two servers and two clients.
2983 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2985 * Implemented SIGNOFF notify type handling in silc_server_notify
2988 * silc_server_remove_id now removes the client entry from all channels
2989 it has joined and thusly sends SIGNOFF notify type.
2991 * Rewrote the NAMES list generation in server by removing two excess
2992 loops. The lists are created now inside one loop.
2994 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2996 * silc_server_remove_channel_user checks now also global list
2997 for channel and client.
2999 * silc_server_new_channel_user checks now both local and global
3000 list for channel and client. Fixed a bug in client id decoding.
3001 Used to decode wrong buffer.
3003 * silc_server_channel_message checks now both local and global
3004 list for channel entry.
3006 * Tested channel joining (hence JOIN) in router environment
3007 successfully. Tested with two routers, two servers and two
3010 * Tested channel message sending in router environment successfully.
3012 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * Added silc_server_save_channel_key into server.[ch] to save the
3015 received channel key in Channel Key payload processing. It is
3016 also used in JOIN command reply handling.
3018 Equivalent function silc_client_save_channel_key added into
3019 client.[ch] into client library.
3021 * Changed JOIN command reply to send information whether the channel
3022 was created or not (is existing already) and the channel key
3023 payload. Changed protocol specs accordingly.
3025 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3026 the request was sent by ID and not by nickname. Crashed on
3029 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3032 now correctly save the received data.
3034 * silc_server_free_sock_user_data now notifies routers in the
3035 network about entities leaving the network.
3037 At the same time implemented functions silc_server_remove_id
3038 and silc_server_send_remove_id to receive and send REMOVE_ID
3039 packets. The packet is used to notify routers in the network
3040 about leaving entities. The ID removed will become invalid in
3043 * Added function silc_idlist_del_server into server. Removes and
3044 free's server entry from ID list.
3046 * silc_server_private_message function now checks, if we are router,
3047 that the destination ID really is valid ID, naturally.
3049 * In router when NEW_ID packet is received (for new client) the
3050 hash of the Client ID is saved in the ID Cache but the
3051 client->nickname is set to NULL, instead of putting the hash
3054 IDENTIFY command now also checks that client->nickname must be
3055 valid. If it is not if will request the data from the server who
3056 owns the client. Added new function
3057 silc_server_command_identify_check.
3059 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3060 to set the command to already allocated Command Payload.
3062 * Tested private message sending in router environment with two
3063 routers, two servers and two clients. Fixed minor bugs and now
3066 * Fixed segfault from client's NAMES command. Used to crash if
3069 * Forwarded packets must not be routed even if it is not destined
3070 to the receiver. Changed server code comply with this.
3072 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Added `require_reverse_mapping' boolean value to ServerParams
3075 structure. If TRUE (not default) the server will require that
3076 the connecting host has fully qualified domain name.
3078 If the reverse mapping is not required and hostname could not be
3079 found the IP address is used as hostname.
3081 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Implemented version string checking to both client and server.
3084 The check is incomplete currently due to the abnormal version
3085 strings used in development version of SILC.
3087 * Changed all command functions in server to use the new
3090 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Changed char *data to unsigned char *data in ID Cache system to
3093 support binary data as ID Cache data. Changed code to support
3094 binary data in lib/silccore/idcache.c.
3096 * Renamed silc_server_packet_relay_command_reply to
3097 silc_server_command_reply as it is normal packet receiving
3098 function. Rewrote the function to accept command replys for
3099 servers and not only for clients.
3101 * Mark remote router always as registered server if we are connecting
3102 to it. Otherwise, commands sent by the router to us are ignored.
3104 * All ID List find routines now returns the ID Cache Entry pointer
3105 as well if requested.
3107 * WHOIS command works now in router environment, tested with two
3108 routers, two servers and two clients.
3110 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3111 in router environment (as it is almost equivalent to WHOIS) but
3112 hasn't been tested thoroughly. Added new functions:
3114 silc_server_command_identify_parse
3115 silc_server_command_identify_send_reply
3116 silc_server_command_identify_from_client
3117 silc_server_command_identify_from_server
3119 * Disabled route cache adding because adding two different ID's with
3120 same IP replaces the old cache entry thus giving wrong route.
3121 The entry->router->connection is always the fastest route anyway
3122 so route cache may not be needed. Of course, new routes maybe
3123 established after receiving the ID when the entry->router->connection
3124 might not be anymore the most optimal.
3126 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * Add route cache for received ID for fast routing.
3130 * Added silc_server_packet_route to route received packet on router
3131 that is not destined to us.
3133 * Renamed silc_server_get_route to silc_server_route_get.
3135 * Added id_string and id_string_len fields into SilcServer to
3136 include encoded ServerID for fast comparing without excess
3137 encoding of the ID's.
3139 * Cleaned up WHOIS command on server side. Added following static
3142 silc_server_command_whois_parse
3143 silc_server_command_whois_check
3144 silc_server_command_whois_send_reply
3145 silc_server_command_whois_from_client
3146 silc_server_command_whois_from_server
3148 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3149 arguments in command replies. All command functions should be
3150 updated to use this macro.
3152 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3154 * Minor typo fixes on command reply handling on server.
3156 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * Added silc_server_command_add_to_channel internal routine to add
3159 the client to the channel after router has created the channel and
3160 sent command reply to the server.
3162 * Added generic silc_server_send_command to send any command from
3165 * Use static buffer with ID rendering instead of duplicating data.
3167 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Fixed a channel user mode bug when joining to a channel server gave
3170 everybody channel founder rights, oops.
3172 * We mark ourselves as the router of the incoming server connection
3173 if we are router ourselves. This way we can check in some packet
3174 sending functions whether it is locally connected server. For
3175 incoming router connections we put NULL.
3177 * For router sending packets locally means now always sending the
3178 packet cell wide; to local clients and local servers. For normal
3179 server sending packet locally means sending it to only local
3182 * Fixed the JOIN command to really work in router environment. If the
3183 channel is created it is always created by the router. Router is
3184 also responsible of making the initial joining to the channel,
3185 sending JOIN notify to the sending server and distributing
3186 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3187 does not exist server doesn't do anything else but forward the
3188 command to the router which performs everything.
3190 * Added silc_server_send_channel_key function to send the Channel Key
3193 * Added silc_server_create_channel_key to create new channel key. The
3194 channel key is now re-generated everytime someone joins or leaves
3195 a channel, as protocol dictates. Note: channel->key_len is the
3198 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3201 packet_receive.[ch] to separate packet sending and receiving
3202 routines. The server.[ch] now includes everything else including
3203 actual packet processing (writing and reading data) and other
3206 Renamed silc_server_private_message_send_internal to
3207 silc_server_send_private_message. The routine is still though
3208 used only to relay private messages as server does not send
3209 private messages itself.
3211 Renamed silc_server_new_channel to silc_server_create_new_channel
3212 and added new function sicl_server_new_channel that handles the
3213 incoming New Channel packet. Added also new sending function
3214 silc_server_send_new_channel to send New Channel Payload.
3216 * Added new function silc_server_notify to process incoming notify
3217 packet to the server/router. Server may then relay the notify
3218 to clients if needed.
3220 * Added new function silc_server_new_channel_user to process incoming
3221 New Channel User packet. Router will redistribute the packet and
3222 send JOIN notify to its local clients and locally connected servers
3223 if needed. Normal server will send JOIN notify to its local client
3224 on same channel when received this packet. Added also corresponding
3225 sending function silc_server_send_new_channel_user to sent the
3228 * Added boolean route argument to send_notif_to_channel and
3229 packet_send_to_channel functions to attempt to route the packet
3230 if it is TRUE and send only locally if it is FALSE.
3232 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * silc_server_replace_id now broadcasts the received replace ID
3235 packet if it is not broadcast packet already. The router must
3236 broadcast to inform other routers about changed ID.
3238 * Added backpointer to server's router into SilcServer context in
3239 silcd/server_internal.h.
3241 * Fixed silc_server_packet_broadcast to send correct broadcast
3244 * The channel key is now distributed to the local client as soon
3245 as it is received from the router (in router environment) so that
3246 no other packet may be sent for the channel until client has
3249 * silc_server_remove_channel_user now broadcasts the received
3250 Remove Channel User packet if it is not broadcast packet already.
3251 The router must broadcast to inform other routers about removed
3254 * Added users field into SilcPacketContext that is a reference count
3255 of the context. One can increase the reference count by calling
3256 silc_packet_context_dup which is now changed to just increase the
3257 reference count instead of duplicating the data. The reference
3258 count is decresed by calling silc_packet_context_free that will
3259 free the data after the reference count hits zero.
3261 For now on the packet context and everything allocated into it
3262 (including the raw packet from network) must be freed by calling
3263 the new silc_packet_context_free function. Added also new function
3264 silc_packet_context_alloc that must be used now to allocate the
3265 context. This also means that if a routine is asynchronous from
3266 silc_[client/server]_packet_parse_type the packet context must
3267 be duplicated by calling silc_packet_context_dup. Otherwise it
3268 gets free'd after silc_[client/server]_packet_parse_type returns.
3269 Also, one must remember that if packet is duplicated then its
3270 reference count must be decresed by calling the free function as
3271 many times as it was duplicated.
3273 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3274 from both client and server.
3276 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3278 * Made joining to a channel working in router environment.
3280 * Cleaned up JOIN command on server side and create function
3281 silc_server_command_join_channel internal routine to make the
3284 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3286 * Changed silc_command_pending list to SilcDList. Also, added
3287 `ident' field to SilcServerCommandPending structure to identify
3288 the reply and to call correct callback.
3290 Added silc_server_command_pending_check function to replace the
3291 corresnponding macro. The silc_command_pending list is not
3294 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3295 to set identifier to previously allocated Command Payload. It
3296 is used to set identifier for command when resending Command
3299 * Added silc_command_payload_encode_payload to encode Command
3300 Payload buffer from SilcCommandPayload structure.
3302 * Added silc_argument_payload_encode_payload to encode Argument
3303 payload buffer from SilcArgumentPayload structure.
3305 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Changed WHOIS command to support router connection on server side.
3308 The whois request is always sent to router unless the server is
3309 standalone server. After server has received the reply from the
3310 router will it send the reply to the client.
3312 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3313 broadcast received broadcast packet. The function is used only
3314 by router. The broadcast packet is always sent to the router's
3317 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3318 render given ID to printable string, for log files for example.
3320 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * Made basic router to router connections working. At least they
3323 can now connect to each other but nothing really works the way
3324 they are supposed - yet.
3326 * Added new initiator token to RouterConnection configuration
3327 file in silcd/serverconfig.[ch]. It is used to tell whether we
3328 are the initiator to the remote router or whether we'll expect
3329 the other end to connect.
3331 * Moved registering of listener task to silc_server_init, hence
3332 the server starts listenning as soon as it is run, even if it
3333 does not have connections to other routers. Let's see how well
3336 * Changed default connection retry timeouts for more suitable in
3339 * Removed cipher and such arguments from silc_idlist_add_client
3340 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3341 Added new function silc_idlist_add_data to add the keys and stuff
3344 * Added SilcIDListData structure and added it to SilcClientEntry
3345 and SilcServerEntry as their first field in the structure. This
3346 way we can explicitly cast the ID entries to the SilcIDListData
3347 structure and get common data for the entries. In past, we had
3348 to first check what type of connection it is and then cast it to
3349 correct ID entry type. Now, we can directly cast the opaque
3350 pointer to the SilcIDListData (no matter what ID entry it actually
3351 is) and get the data needed.
3353 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3355 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3356 in some circumstances even if threre were timeout tasks, though not
3357 IO tasks, but tasks anyway. Now fixed.
3359 * Defined SilcServerConnection structure to hold connection specific
3360 stuff about directly connected servers and routers. The definition
3361 is currently in silcd/server_internal.h. I thought about having
3362 a bit more important role fro this struct but for now it is used
3363 only when connecting to other server (or router actually).
3365 * Added connecting retry support in server when connecting to
3366 router(s). The retry feature implement exponential backoff
3367 algorithm. Also, added SilcServerParams structure to hold default
3368 parameters for server. For now, it include these retry settings
3369 and are hard coded. After server is moded to be as Silc Server
3370 Library this structure will be more important.
3372 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3374 * Changed client librarys channel->clients table to SilcList and
3375 changed code accordingly.
3377 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3379 * Changed client's channel table to SilcList and changed code
3380 accordingly. Also changed SilcChannelClientEntry to include back-
3381 pointer to the channel so that client entry can use that structure
3382 as list as well and we have fast cross-reference to the channel.
3383 This change dramatically decreased the complexity of channel
3384 handling with client entry and vice versa (removed one extra
3385 loop when searching for channel entry from many functions).
3387 * Changed server->sim from table to SilcDList and changed code
3390 * NAMES command can now be used from user interface. It will show
3391 the user list on the channel, neatly.
3393 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3394 Code now saves realname of the user if it becomes available.
3396 * Renamed configure.in to configure.in.pre and made ./prepare
3397 script to automatically add correct version string to
3398 configure.in which it creates from configure.in.pre.
3400 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * NAMES command reply now shows users mode with the nickname when
3405 * Moved silc_client_ch[u]mode[_char] functions from
3406 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3407 place sucks, they are utility functions and should be in some
3410 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3412 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3415 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Added TRQ (efficient deque and list library) into lib/trq. This is
3420 a very good list library that is currently used in the SILC. Defined
3421 SilcList API over the library because I didn't like the API very
3422 much. See lib/trq/silclist.h for the API and examples of how to
3423 use the API. Fixed various places in the code to use the new
3424 SilcList API. The SilcList is meant for lists that has a structure
3425 already defined as a list. It is not suitable to add just some
3426 context to the list (in TRQ, the context is the list actually).
3428 So, I defined SilcDList that can be used for the purpose where
3429 predefined list structure does not exit. This can be used as
3430 such list. Now some context just can be added to the SilcDList.
3431 Currently this list is not used in the SILC just yet, though there
3432 are a lot places where this can replace dynamically allocated
3433 tables and I will fix these places, later, to use SilcDList.
3434 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3435 and use TRQ internally).
3437 Also fixed some annoying warning messages that the original TRQ
3438 code generated. Also minor changes to TRQ's Makefile.in.
3440 * Added support for querying by Client ID to both WHOIS and
3441 IDENTIFY commands into server, as required by the protocol.
3443 * Removed method function pointers from SilcBuffer structure. They
3444 weren't used to anything and just increased the context size for
3445 no good reason. This change also made silc_buffer_alloc and
3446 silc_buffer_free functions inline functions.
3448 * Disabled command flooding detection support until it's fixed so
3449 that it accepts commands in but does not execute them more than once
3452 * Added silc_net_localhost(), to return local hostname, into
3453 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3454 that must be initialized before calling silc_client_init.
3456 * Added new function: silc_server_send_notify_on_channels to send
3457 notify messages to all channels client has joined. It is assured
3458 that the message is sent only once per client.
3460 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3461 lib/silcutil/silcutil.[ch] as silc_format function. The new
3462 function is generic and is used by server as well, not only by
3463 the logging routines.
3465 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3466 the provided version string was not acceptable. Added new function:
3467 silc_ske_check_version into lib/silcske/silcske.h. The function
3468 must be implemented by the application (client or server) and it
3469 does not reside in the SKE library. The function checks the version
3470 string remote end sent.
3472 * Added back pointers (to opaque context and to SilcSocketConnection)
3473 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3475 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3476 duplicate packet context structure.
3478 * Changed `notify' client operation to send same arguments as client
3479 receives from server except for ID's. ID's are mapped to correct
3480 ID entry and that is returned. Also, if channel entry is not sent
3481 by server but the notify is for channel the channel entry is sent
3482 to application (otherwise application doesn't know that it is for
3483 channel (library gets it from packet's Destination ID)).
3485 * Added silc_client_remove_from_channels into client library to
3486 remove a client from all channels it has joined to. Used when
3487 received SIGNOFF notify from server. Added also new function
3488 silc_client_replace_from_channels to replace old ID entry with
3489 new ID entry on all channels. Used when received NICK_CHANGE
3492 * Fixed ID Cache list handling in silc_idlist_get_client in
3493 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3494 to get (or query) client by ID.
3496 * Updated TODO list.
3498 * Added connection authentication status message defined by the
3499 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3500 support for these into the code in client and server side.
3502 * Added generic function silc_client_send_command to send any command
3503 with variable argument list. Application should use this function
3504 to send commands if the command functions provided by the library
3505 does not suite for the application's user interface needs.
3507 * Added new `failure' client operation. Application is notified about
3508 received failure packet if client is executing a protocol. In this
3509 case the protocol's execution has failed.
3511 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3512 is required by the protocol.
3514 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3515 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3518 * Added status flag to SilcSKE object to indicate realtime status
3519 of the SKE protocol.
3521 * Application receives now exactly same command reply arguments as
3522 the library receives from server. However, if ID is received the
3523 corresponding ID entry is returned to the application (eg. Client
3524 ID is mapped to correct SilcClientEntry entry and that is returned).
3525 Changed command_reply client operation due to this change.
3527 * Changed all ID's in commands and in command replys as ID Payloads.
3528 Change affected both client and server side codes.
3530 All ID's sent in SILC network (with execption of ID's in SILC
3531 Packet header) are sent in ID Payload to support variable length
3534 * Server now notifies nick changes and notifies all clients on
3535 the channels about the new nickname (about the new Client ID,
3538 * Implemented CMODE command to change channel modes. Supports all
3539 channel modes defined by the protocol specs except ban and invite
3540 lists. (Also, private channel key mode is supported but support for
3541 setting private channel key in client is missing, thus, this mode
3542 has no effect on client side (except that server requires that the
3543 client uses private channel key and normal channel traffic does not
3546 Also, invite mode works per se, but INVITE command does not work
3547 yet correctly, so you can set channel as invite only channel but
3548 inviting clients to the channel does not work (it is yet to be
3549 thought what's the best way to do it).
3551 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3552 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3553 Implemented CUMODE command to change user's mode on the channel.
3554 Supports all modes defined by the protocol specs.
3556 * Added NAMES command reply to return users modes on the channel.
3558 * Removed unnecessary and slow ciphers from lib/silccrypt.
3560 * Set SO_KEEPALIVE option to connection sockets by default.
3562 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3564 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3565 redefined the Notify Payload into protocol specs.
3567 * Added silc_id_payload_parse_id to get ID directly from raw
3570 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3572 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3573 accept searching by Client ID as well.
3575 * Added support for LEAVE and SIGNOFF notify types in client library.
3577 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3578 to parse ID Payload from raw data.
3580 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Added flags parameter into silc_ske_assemble_security_properties
3583 function in lib/silcske/silcske.[ch].
3585 * Changed notify client operation to fit better for notify messages
3586 sent by server. The notify payload received from server is now
3587 passed to the application (after parsing it to SilcNotifyPayload).
3588 It is application's responsibility to retrieve the arguments
3589 from the payload and show the message the way it wants. The message
3590 sent by server is implementation specific.
3592 * Changed public keys to comply with the protocol specification.
3593 Old public keys are not supported anymore and are not compatible.
3595 * Removed nickname from Channel Payload as the latest draft removed
3596 it. The client must resolve the nickname from the NAMES command
3597 reply received when it joined the channel.
3599 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3601 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3603 * Fixed some errors in protocol specification drafts.
3605 * Created lib/silccore/silcnotify.c to implement Notify Payload
3606 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3607 generic payloads described by protocol specifications. The file
3608 includes implementations for ID Payload and Argument Payload.
3610 * Changed Command Payload implementation to use the new Argument
3611 Payload. Changed command_xxxx_payload to command_payload_xxxx
3612 to comply with SILC coding conventions.
3614 * Added suppport for Argument Payload handling in Notify Payload
3615 implementation as protocol requires it. Added the new support
3616 into server and client lib as well.
3618 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3620 * Added support for multiple nicknames on same channel. [n] is
3621 added locally to the nickname if there are more than one same
3622 nicknames on the channel.
3624 * Server now sends all nicknames that matched WHOIS request.
3625 Client also shows the list received from server.
3627 * Added TOPIC command to client side. User can now set and show
3628 current topic on channel.
3630 * Added MOTD command to client and server. Also, server sends the
3631 motd when client connects to the server.
3633 * Changed version strings to comply ISO 8601.
3635 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * Fixed protocol error handling in client library. It should now
3638 cope even if the SKE fails for some reason.
3640 * Made new protocol specification drafts for submitting to IETF.
3642 * Implemented TOPIC command to server in silcd/command.c.
3644 * Added two new notify types into lib/silccore/silcnotify.h:
3645 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3646 notify nickname change and topic setting/change on a channel.
3648 * API change of command_reply operation in client library. The
3649 application gets now the status type received from server as well.
3651 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3653 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3655 * Cras fixed and optimized the packet handling even further and
3656 it should work now. Minor change to the prototype of function
3657 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3659 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * Added new function into lib/silcutil/silcschedule.[ch]:
3662 silc_schedule_with_fd to select() a specified fd. The function
3663 returns after timeout expires or data arrives or goes. The
3664 function is used by packet routines to wait that all data is
3665 received from network.
3667 * Fixed data reading from network in lib/silccore/silcpacket.c.
3668 The code now assures that all data is read from the fd and then
3669 continues packet processing. This was a bug fix since the code
3670 used to drop some data in some circumstances.
3672 * Added new function into lib/silcclient/client.[ch]:
3673 silc_client_start_key_exchange to start key exchange after
3674 connection has been established to server. The code internally
3675 now uses this funtion but its main purpose was to provide it
3676 for applications that perform their own connecting. After
3677 application has created a connection it merely calls this
3678 function to start the key exchange between client and server.
3679 The library takes care of everything else after that.
3681 Updated also lib/silcclient/README to explain the usage of
3684 * Do not send to application information that connection has
3685 been established. Application gets notified it by connect
3688 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3690 * Applied cras's patch to add silc_schedule_one function. The
3691 function runs scheduler once and returns.
3693 * Fixed the scheduler after cras messed it up. The timeout
3694 handling works now as it's supposed to work.
3696 * Added into lib/silccore/ silcnotify.h to include notify
3697 message types support. Changed silc_server_send_notify*
3698 functions, in server.[ch], to support those new notify types.
3699 Added the support for the notify types into client library,
3700 as well. Added new notify client operation into ops.h in
3703 * Changed silc_server_packet_send_to_channel to send normal
3704 packets instead of just channel message packets. The function
3705 is now used to send the notify packets to channels. It is not
3706 used to send channel message packets anymore, as server never
3709 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3710 va_arg()s as it seems to require it nowadays. I guess, if SILC
3711 is compiled with older va_arg() the new code should work anyway.
3713 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3715 * Splitted core library. Core library (lib/silccore) includes
3716 now only SILC protocol specific core (and common) components.
3717 Created new utility library (lib/silcutil) that includes more
3718 generic purpose stuff. The stuff for util library was taken
3719 from the old core library. This was minor and easy split.
3721 * Created SILC Client Library (lib/silcclient) that includes
3722 implementation of the SILC client without user interface. This
3723 was major move from silc/ directory. The code has been changed
3724 so that it is transparent towards the user interface. The
3725 silc/ directory includes now the same user interface as before
3726 and it uses the new client library. Read lib/silcclient/README.
3727 Basicly, the client library performs everything else related
3728 to SILC except user interface handling. Also, configuration
3729 files are considered to be part of user interface and library
3730 does not handle them.
3732 This change also changed a lot of structures, function naming etc.
3733 Most important change was that SilcClientWindow object was
3734 renamed to SilcClientConnection in the client library. Created
3735 also new file lib/silcclient/ops.h. Also added new files
3736 silc/local_command.[ch] and silc/client_ops.[ch].
3738 All these changes were made to make it easier for user interface
3739 designers to create what ever user interface for the SILC client
3742 It is also expected that the server will be moved to lib
3743 directory as well and SILC Server Library will be created;
3744 sometimes in the future.
3746 * Removed Local commands from lib/silccore/silccommand.h as
3747 they are application specific and new client library does not
3748 handle any of those anymore.
3750 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3751 old client implementation in silc/.
3753 * Added support for callback functions in SILC_LOG_* macros.
3754 Application can now set its own callbacks that will be called
3755 instead of using the default functions that will always print
3756 the debug messages to stderr (or stdout). Also, debugging can
3757 now be disabled by setting silc_debug to FALSE and re-enabled by
3758 setting it to TRUE. Note, that logging will still work even
3759 if debugging is disabled.
3761 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3762 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3763 silc_log_reset_debug_callbacks.
3765 * To enable debugging in silc client one must give now -d
3766 option on command line.
3768 * Changed silc_schedule_init to automatically allocate task queues
3769 if they are not allocated before calling it.
3771 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3773 * Added GMP 3.1 into math library.
3775 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3777 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3778 a channel in SILC network. The packet is used by servers and
3779 routers to notify other routers that user has left a channel.
3780 This little feature was missing until now. Added the feature
3781 to protocol specification as well.
3783 Added functions: silc_server_send_remove_channel_user and
3784 silc_server_remove_channel_user into server.[ch].
3786 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3787 lib/silccore/silcpacket.h. However, they are not implemented
3790 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Fixed joining to a channel and sending channel messages
3793 between server and router. The channel message sending should
3794 now work inside a cell.
3796 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Fixed the private message sending between server and router.
3799 The private message sending should now work inside a cell.
3801 * Added silc_server_replace_id into server.[ch] to replace
3802 existing ID in the SILC network.
3804 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3805 and silc_idlist_replace_server_id into idlist.[ch] in server.
3807 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Fixed the server to server connections. Server can again now
3810 connect to router. Router to router connections probably does
3813 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Added dynamic protocol registering support. Now protocols can
3816 registered and unregistered on the fly. Patch by cras.
3818 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Added lib/contrib directory to hold routines that some platforms
3821 don't have but are needed by SILC.
3823 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3824 into lin/contrib to provide getopt() and getopt_long() for
3825 those who don't have it.
3827 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Added AWAY command to client. When away message is set and
3830 client receives a private message packet the client automatically
3831 replies to the sender with the away message.
3833 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3834 bug seemed to be the cause of recent problems when compiling
3837 * Added version detection support to SKE protocol specification
3838 and added the new changes to the SKE implementation as well.
3839 There were other minor changes in the SKE protocol as well.
3841 Many changes in lib/silcske/silcske.[ch] and in
3842 lib/silcske/payload.[ch].
3844 * Added ^U functionality, clear input line. Patch from cras.
3846 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3848 * Mainly small bugfixes on core library. Fixed some debugging
3849 logging and buffer overflow in silclog.c.
3851 * Updated config.sub and config.guess on the distribution tree.
3853 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3855 * Added command lagging support in server. Client may execute
3856 commands now only once in two seconds.
3858 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Optimized packet reception. MAC computation and checking is now
3861 also more optimized. A lot previously duplicated code is now
3862 used as generic by both client and server.
3864 * Fixed key pair generation in clientutil.c
3866 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3868 * Added into lib/silccore/silcbufutil.[ch] new function;
3869 silc_buffer_realloc.
3871 * Moved generic packet sending/encryption functions to
3872 lib/silccore/silcpacket.[ch] from client and server. Some
3873 rewriting of the functions.
3875 * Moved all generic packet reception/decryption functions to
3876 lib/silccore/silcpacket.[ch] from client and server. The
3877 packet processing is now much cleaner in both client and server.
3878 These were major changes in both client and server.
3880 * Created many common functions in server to do packet sending.
3881 Previously code were duplicated a lot, this has been removed
3884 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3886 * Rewrote major parts of the ID cache system. Don't know
3887 whether it is better now or not but at least the API is more
3890 * Major rewrite on ID cache stuff on client because of the ID
3891 cache API changes. Added idlist.c to client.
3893 * Also major rewrite on ID cache stuff on server as well.
3894 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3895 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3896 in hand, instead they are all put into the ID cache system now.
3897 All server_idlist_* routines uses ID cache now instead of
3898 traversing its own lists (those lists does not exist anymore).
3899 SilcIDList though still exists. Also, SilcXXXEntry's are
3902 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3904 * Finally made the SKE implementation compliant to the protocol
3905 specification. All mp integers are now binary encoded as
3906 opposed being HEX encoded.
3908 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3911 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3912 functions: silc_[encode/decode]_pem. Also added function
3913 silc_encode_pem_file to PEM encode with newlines ('\n') for
3916 * SILC public keys are now encoded either PEM or binary. Same
3917 option is for private keys as well. By default private keys
3918 are binary encoded and public keys PEM encoded. Silly HEX
3919 encoding were removed.
3921 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3922 function to create fingerprints.
3924 * Fixed a bug in SHA1; does not change the original data anymore.
3926 * Partly implemented INFO command on client and server side.
3927 Fixed CLEAR command. Changes to SERVER command; show current
3928 server(s) when giving command without arguments. Added
3929 VERSION command to client.
3931 * Added check to server that unregistered connections cannot
3932 execute commands (unless it is specificly allowed).
3934 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3936 * Fixed screen refresh.
3938 * Fixed channel joining bug from client. On some circumstances
3939 client tried to join to a channel it had already joined.
3941 * Added public key verification process into client's protocol.c.
3942 The client now verifies the public key from user and saves
3943 it into ~./silc/serverkeys/ directory.
3945 Added into: clientutil.[ch]: silc_client_verify_server_key.
3947 * Changed SKE protocol's silc_ske_initiator_finish function
3948 to accept callback function that verifies the received public
3949 key. Removed old silc_ske_verify_public_key function.
3951 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3954 silc_pkcs_private_key[_data]_set.
3956 * Made the password and public authentication more cleaner in
3957 server's protocol.c.
3959 * Removed historic and obsolete protocol `channel_auth' from
3960 both client and server.
3962 * Removed wrong way of sending command status messages from
3963 server to client in server's command.c. The old way violated
3964 protocol specification.
3966 Changes to silccore/silccommand.[ch]: removed
3967 silc_command_encode_status_payload -> not needed anymore,
3968 changed silc_command_encode_payload_va to accept extra
3969 argument on variable argument list. The argument type must
3970 now be provided to the function. Also, added new function:
3971 silc_command_encode_reply_payload_va which is same as
3972 normal command_encode_payload_va except command status type
3973 is provided as extra argument.
3975 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3977 * Added ~./silc directory handling. The directory includes the
3978 public and private keys for the client.
3980 Added silc_client_check_silc_dir, silc_client_create_identifier
3981 and silc_client_load_keys.
3983 * Implemented SILC protocol compliant public key. Added public
3984 and private key saving to and loading from files.
3986 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3987 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3988 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3989 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3990 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3992 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3993 silc_pkcs_load_[public/private]_key.
3995 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3997 * Added silc_server_get_route (route.[ch]) to get connection
3998 data for the fastest route for given ID.
4000 * Implemented INVITE command on client and server. The command
4001 were re-defined in the SILC Protocol Specification and the
4002 implementation now complies with the specification.
4004 * Implemented PING command on client and server.
4006 * Implemented NAMES command on client and server. The server side
4007 supports currently only normal server not router server yet.
4008 Some changes to NAMES definition in SILC protocol specification.
4010 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Implemented LEAVE command on client and server.
4014 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4015 again. This change was made to the protocol as well. Server
4016 should not violate the protocol specification anymore.
4018 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4021 was tested. SOCKS4 was not but should work anyway.
