1 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Close log file after open. Affected file
4 lib/silcutil/silclog.c.
6 * Check whether sock == NULL in silc_client_send_packet and return
7 if it is. Affected file lib/silcclient/silcclient.c.
9 * Check rec->entry == NULL in the Irssi SILC Client before
10 sending the channel message. Affecte file is
11 irssi/src/silc/core/silc-servers.c.
13 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
15 * Merged a splitted window bugfix from Irssi CVS tree. The
16 affected file is irssi/src/fe-text/textbuffer-view.c.
18 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
19 It did not print nickname.
21 * Improved the distributions system a bit.
23 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
25 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
26 irssi/src/fe-text/gui-window.c.
28 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
29 to in-active server. The affected file is
30 irssi/src/silc/core/client_ops.c.
32 * Resolve the client in USERS command reply if the entry does
33 not have username resolved. The affected file is
34 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
35 command to WHOIS command to really resolve stuff. The USERS
36 is not used any more in any critical section so WHOIS can
37 be used even though it might be slower than IDENTIFY.
39 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
42 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
44 * Changed the protocol API a bit more consistent in the
45 lib/silccore/silcprotocol.[ch].
47 * Changed the following headers to ROBODoc format:
49 lib/silccore/silcpayload.h
50 lib/silccore/silcprotocol.h
51 lib/silccore/silcsockconn.h
53 All core library headers are now formatted.
55 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
57 * Fixed a bug in Irssi SILC client; do not show that you are
58 server/router operator if you really are not. Affected file is
59 irssi/src/silc/core/client_ops.c.
61 * Renamed silc_command_free_payload to silc_command_payload_free.
62 Affected file lib/silccore/silccommand.h
64 * Added silcmath.h to include the prototoypes of various routines
65 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
68 * Changed the following headers to ROBODoc format:
70 lib/silccore/silcchannel.h
71 lib/silccore/silccommand.h
73 lib/silccore/silcidcache.h
74 lib/silccore/silcmode.h
75 lib/silccore/silcnotify.h
76 lib/silccore/silcpacket.h
77 lib/silcmath/silcmath.h
79 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
81 * Added checking to the server code not to start the server if
82 ciphers and stuff are not configured properly. Affected files
83 silcd/serverconfig.[h] and silcd/server.c.
85 * Changed the layout of the header files of the public interfaces
86 in the SILC libraries. The new layout supports ROBODoc
87 documentation tool (and some others) so that it is easy to create
88 a library reference manual. All the other headers and source
89 code must still follow the CodingStyle document. Also source
90 code must not include these ROBODoc stuffs, only the headers.
91 Furthermore, all public interface headers must now be named
92 by using `silc' prefix, example: silcapi.h, silccipher.h.
93 Some files were renamed due to this. All the other headers
94 must not be used as public interfaces. I will update the
95 CodingStyle document later. Changed following headers, so far:
97 lib/silcclient/silcapi.h
98 lib/silccore/silcauth.h
99 lib/silccore/silcprivate.h
100 lib/silccrypt/silcdh.h
102 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
106 * Removed silc_client_packet_send_flush from the client library
107 as it is not needed. Affected file lib/silcclient/client.[ch].
109 * Added printing of message of unresolved authentication method
110 to the Irssi SILC client. Added it to the module formats.
111 Removed the same message from the client library.
113 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
115 * Added new distribution feature, DISTLABEL. Every distribution
116 can define own preprocessor label that can be used in the
117 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
118 file distributions, acconfig.h.pre and prepare.
120 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
122 * Added Makefile.defines_int to include the actual definitions
123 for Makefile.defines.in. Tested the new distribution system,
124 created distributions and tested installation.
126 * Added AWAY message printing to the Irssi SILC client. Added
127 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
129 * Added SCONNECT command to call the SILC's CONNECT command.
130 Cannot use CONNECT directly since Irssi uses that internally.
131 Affected file irssi/src/silc/core/silc-servers.c.
133 Added ACTION local command. It is same as ME command but takes
134 the channel as mandatory argument.
136 Rewrote some of the Irssi's help files to suite for SILC
139 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Added Makefile.defines[.in] that should for now on be included
142 in all Makefile.am file in the source tree. That file includes
143 all common compilation definitions for SILC source tree.
145 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
147 * Minor changes to the ./prepare script to change the package
148 name according the distribution name to the configure.in.
150 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
152 * Created new distribution system. Added file `distributions'
153 that defines all the distributions that can be created out of
154 the SILC source tree. The ./prepare script now reads that
155 file to determine how to prepare the distributions. The
156 first argument to the ./prepare is the name of the distribution
157 and second is the version of the distribution. If given
158 without arguments it creates the default (toolkit) distribution
159 with the default version (defined in ./prepare).
161 All Makefile.am files that are subject to the distributions
162 are now named as Makefile.am.pre. These are ./Makefile.am
163 and lib/Makefile.am. Others may be changed later.
165 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
167 * Added invite list, ban list, some key management and connection
168 error message printing to module formats in the Irssi SILC client.
170 * Added new silc_client_set_away_message to set the away message
171 that is back to the person who sent private message. The
172 affected file lib/silcclient/silcapi.h and the
173 lib/silcclient/client_prvmsg.c.
175 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
177 * Fixed the private message sending in the Irssi SILC client,
178 added local command KEY to the Irssi SILC client.
180 Added key management and key agreement message formats to the
181 irssi/src/fe-common/silc/module-formats.[ch].
183 Added USERS (alias WHO) printing, server/router operator
184 indication and LIST command printing to the module formats.
186 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
188 * Fixed channel joining notify handling, cumode notify handling
189 from Irssi SILC client.
191 * Added SILC specific module-formats to the Irssi SILC client so
192 that SILC specific message hilighting, colors etc is possible.
193 Affected file irssi/src/fe-common/silc/module-formats.[ch].
195 Added channel mode, channel user mode, actions, notices,
196 whois and whowas printing to the the module-formats.c.
198 * Fixed a bug in channel deletion in the server. The channel
199 is not left to the cache even if the channel founder auth mode
200 is set when there are no users anymore on the channel. Affected
203 * The silc_net_localhost now resolves the entire hostname including
204 the domain name. Affected file lib/silcutil/silcnet.c.
206 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Changed the ask_passphrase client operation to be ascynchronous.
209 It has now a completion callback and a context that the
210 application must call after it has got the passphrase from
211 the user. Affected files lib/silcclient/silcapi.h,
212 lib/silcclient/protocol.c, lib/silcclient/command.c and
215 Added SilcAskPassphrase callback that the application calls
216 to deliver the passphrase to the library.
218 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
219 The public key verification and especially a certificate
220 verification is asynchronous procedure.
222 Added new SILC_SKE_STATUS_PENDING status to indicate the
223 request is pending and a callback will be called to finalize
226 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
227 indicate that remote end did not send its public key (or
228 certificate), even though we require it. Added check for this
229 condition in the SKE. This was a security bug, now fixed.
231 Defined new SilcSKEVerifyCbCompletion callback that is called
232 when the verification process is completed.
234 The affected files lib/silcske/silcske_status.h and
235 lib/silcske/silcske.[ch].
237 * Changed the verify_public_key client operation to be async
238 as well. Defined SilcVerifyPublicKey callback that is used to
239 indicate the success of the public key verification process.
241 Changed the server and client to use the new async client
244 * Changed the Irssi SILC client's internal scheduler to be called
245 twice as many times as it used to be. As a result the client
246 should be a bit faster now. Affected file is
247 irssi/src/silc/core/silc-core.c.
249 * Added support to Irssi SILC client of asynchronous public key
250 verification and passphrase inquiry. Affected file is
251 irssi/src/silc/core/silc-core.c.
253 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
255 * Do not say "You have left channel %s" in client library.
256 Moved it to the application. Affected files are
257 lib/silcclient/command.c and silc/client_ops.c.
259 * Fixed silc_client_get_clients. Command context was not
260 duplicated and was freed memory in the callback. Affected
261 file lib/silcclient/idlist.c.
263 * Do not say "you are now talking..." on JOIN command in the
264 client library. The appliation must handle it.
266 * Do not say ".. changed topic to" in command reply in the
267 client libary. The application must handle it.
269 * Fixed TOPIC command sending in the client library.
271 * Fixed a memory leak in silc_client_command_free in the file
272 lib/silcclient/command.c.
274 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
276 * Imported a modified version of Irssi client to the source tree.
277 The Irssi will be used to create a new client called
278 Irssi SILC. Imported to irssi/.
280 Added silc_core_init_finish function to the Irssi. Affected
281 file irssi/configure.in.
283 A lot changes in the Makefile.ams around the irssi tree.
285 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
287 * Do not rehash if the new size is same as the old size of the
288 hash table, in the silc_hash_table_rehash*. The affected file
289 lib/silcutil/silchashtable.c.
291 * Replaced hash_table_del_by_context calls from the server
292 (when channel->user_list and client->channels) to the
293 hash_table_del as it is sufficient and faster.
295 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
297 * Added silc_hash_table_list, silc_hash_table_get and the
298 SilcHashTableList structure to provide an alternative way to
299 traverse the hash table. The affected files are
300 lib/silcutil/silchashtable.[ch].
302 * Changed the server's idlist routines to use the hash table
303 routines to optimize the code.
305 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
307 * Replaced the client entry's `channel' list and channel entry's
308 `user_list' list to hash tables for optimized lookup. Changed
309 the code to use the hash table interface around the code.
310 Affected file lib/silcd/idlist.[ch].
312 * Added `auto_rehash' boolean argument to the function
313 silc_hash_table_alloc to indicate whether the hash table should
314 auto-rehash when it thinks is appropriate time. It will
315 increase the hash table size if the there is twice as much
316 entries in the table than the size of the table, and will
317 decrease the size if there are twice as less entries than
318 the size of the table.
320 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
322 * Fixed silc_xxx_get_supported to not crash at some circumstances.
324 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * silc_idcache_purge_by_context deletes the entry now by context
327 as it is supposed to do. Affected file lib/silccore/idcache.c.
329 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
330 client is not anymore valid (WHOWAS givens the info) and not
331 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
333 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
335 * Removed the `data' and `data_len' arguments from the ID Cache
336 interfaces and added `name' argument. ID Cache does not handle
337 anymore the binary data only a names associated with given ID.
339 * When hashing a Client ID with silc_hash_id the entire ID is
340 not hashed anymore, instead only the hash of the Client ID is
341 hashed. This way we can access the Client ID from the cache
342 with Client ID but with the hash of the ID (which is a hash of
343 the nickname) as well without any difference in performance.
345 Added also silc_idcache_find_by_id_one_ext to do one on one
346 searching when we have the actual ID. Added also function
347 silc_hash_client_id_compare. The affected files are
348 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
350 * When hashing the name associated with a ID it is always done
351 in lowercase. This way we can access the cache without worrying
352 about case-sensitivity, even though, for example nicknames are
355 * Fixed a bug in server with channel message sending. It put
356 wrong ID type as destination ID. The affected file
359 * silc_idcache_del_by_context now deletes from all hash tables
360 by context. Affected file lib/silccore/idcache.c.
362 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
364 * Changed the client library to use the new ID Cache interface.
365 Changes around the source tree.
367 * Added silc_hash_table_rehash_ext to rehash with specific
368 hash function. Affected file lib/silcutil/silchashtable.[ch].
370 * Added silc_hash_string_compare to compare two strings in the
371 hash table. Affected file lib/silcutil/silcutil.[ch].
373 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
375 * Added new function silc_idcache_del_by_context into the
376 lib/silccore/idcache.[ch].
378 * Changed the server's ID list routines to use the new ID Cache
379 interface. Changes around the source tree.
381 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
383 * Added silc_hash_table_del[_by_context]_ext functions in to the
384 lib/silcutil/silchashtable.[ch].
386 Removed silc_hash_table_find_all* routines and added new
387 silc_hash_table_find_foreach to replace them.
389 Added silc_hash_table_replace_ext function as extended
390 replacing function. Separated the simple hash table interface
391 from the extended hash table interface in the file
392 lib/silcutil/silchashtable.h.
394 * Fixed minor bugs and changed it to use some of the new
395 hash table functions in lib/silccore/idcache.c
397 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
399 * Added new function silc_hash_table_find_all to return all keys
400 in the hash table by the specified key. As the hash table is
401 collision resistant it also makes it possible to have several
402 duplicate keys in the hash table. This function may be used to
403 find all of the keys from the hash.
405 Added user_context arguments to the SilcHashFunction,
406 SilcHashCompare and SilcHashDestructor to deliver user specified
409 Added new fuctions silc_hash_table_find[_all]_ext to do
410 extended lookup with specified hash and compare functions and
411 specified user contexts.
413 Added new function silc_hash_table_add_ext to add the key
414 with specified hash function and user context.
416 Added new function silc_hash_table_foreach to traverse all
417 entrys in the hash table. Added SilcHashForeach callback
420 Added new function silc_hash_table_del_by_context to delete
421 the entry only if the context associated with the key matches.
423 Affected files are lib/silcutil/silchashtable.[ch].
425 * Removed silc_hash_[server/client/channel]_id and added just
426 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
427 silc_hash_id_compare to compare two ID's using as the hash table
428 comparison function. Added also silc_hash_data to hash
429 binary data and silc_hash_data_compare to compare it.
431 * Removed silc_idlist_find_client_by_hash as it is not needed
432 anymore. Affected file silcd/idlist.[ch].
434 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
435 to use internally the SilcHashTable. The new ID Cache is a lot
436 faster than the old one. Some of the ID Cache interface was also
437 rewritten and obsolete and stupid functions were removed.
439 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Added entry_count field to the SilcHashTable to keep the number
442 of the entries in the table. Implemented the function
443 silc_hash_table_rehash. Added new function
444 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
446 Fixed a minor bug in silc_hash_table_free.
448 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
449 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
450 into the lib/silcutil/silcutil.[ch].
452 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Implemented a collision resistant hash table into the
455 lib/silcutil/silchashtable[ch]. See the header and the source
456 for the SilcHashTable API.
458 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
460 * Merged dotconf version 1.0.2 into lib/dotconf.
462 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
464 * Do not compile anything in lib/silcsim/* if the SIM support
465 is not enabled. The tree should now compile without problems
468 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
470 * Compiled the SILC under cygwin. Compiled and tested briefly
471 without problems. More tests needed. The SIMs didn't compile
474 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
476 * Fixed possible crash in silc_get_username in the
477 lib/silcutil/silcutil.c.
479 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Fixed a va_arg in silc/client_ops.c.
483 * Oops, RC5 routines were named AES and caused some problems
484 when not using SIM's. Affected file lib/silccrypt/rc5.c.
486 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
488 * Added new SilcIDIP structure into the lib/silccore/id.h and
489 replaced the old `ip' fields from all SILC ID's to that type.
490 This is a step towards IPv6 support.
492 The silc_id_get_len takes now the ID as an extra argument.
493 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
494 both IPv4 and IPv6 based ID's.
496 The affected files are lib/silccore/id.[ch] and other files
497 around the tree using these routines.
499 * Removed the ID length arguments in server from various
500 silc_server_send_notify_* routines -> they are not needed
503 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
505 * Fixed memory leak in silc_encode_pem_file in the file
506 lib/silcutil/silcutil.c.
508 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
510 * Check minor version as well in the SKE. Affected files are
511 silcd/protocol.c and lib/silcclient/protocol.c.
513 * Added --identifier option to the server so that an identifier
514 can be when creating the public key for the server. Affected
515 file is silcd/silcd.c.
517 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
518 lib/silccrypt/silcpkcs.c.
520 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
522 * Register default ciphers and stuff when using -C option with
523 the server. Affected file sildc/silcd.c.
525 * Put back the servers public key filename format, it is better
526 than the new one. For now, the client keys are saved with the
527 new filename format. The affected file silc/client_ops.c.
529 * Implemented the Cipher API for the rest of the ciphers that
530 did not implement it or implemented it the wrong way.
532 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
534 * Register default ciphers and stuff when using the -S option
535 in the client. Affected file silc/silc.c. Same also when
536 creating new key pair with -C option.
538 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
540 * Fixed the silc_verify_public_key client operation function to
541 save the public keys differently. The fingerprint is now
542 used as filename and not the hostname. This way also the
543 client keys are saved uniquely and not with hostnames. The
544 affected file is silc/client_ops.c.
546 * Trimmed the silc_hash_fingerprint function to remove extra
547 whitespaces from the end of the fingerprint. The affected
548 file is lib/silccrypt/silchash.c.
552 * Added silc_cipher_register_default function to register all
553 default ciphers. It can be used when configuration files
554 does not exist and the application does not want any specific
555 ciphers in any specific order.
557 The SilcDList is now used as silc_cipher_list dynamically
558 allocated cipher list. Removed the static list all together
559 and now all ciphers must be allocated to the dynamic list.
560 The silc_cipher_alloc routine was changed to check only the
563 All silc_cipher_* routines that used to return int returns
566 The affected files lib/silccrypt/silccrypt.[ch].
568 * The same thing was done to silc_hash_* as for silc_cipher_*
569 routines. Affected files lib/silccrypt/silchash.[ch].
571 * The same thing was done to silc_pkcs_* as for silc_cipher_*
572 routines. Affected files lib/silccrypt/silcpkcs.[ch].
573 Added also silc_pkcs_[un]register[_default] functions.
574 Removed the data_context from the PKCS API.
576 * Added silc_hmac_register_default function to register default
577 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
578 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
579 to unregister all hmacs at once.
581 * Register the default ciphers, hash functions, PKCSs and HMACs
582 if client's configuration file does not exist. The affected
585 * The client did not load the hash functions from the SIM
586 modules at all. Added support for this. Affected file is
589 * When decoding public key with silc_pkcs_public_key_decode, check
590 the supported algorithm only if PKCS are registered. Affected
591 file lib/silccrypt/silcpkcs.c. The same was done with the
592 silc_pkcs_private_key_decode.
594 * Fixed the SILC List routines to keep the list always in order.
595 It used to change the list's order when traversing the list but
596 not it preserves the order. Affected file lib/trq/silclist.h.
598 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
600 * Added the client library to use the SilcSocketConnection's
601 reference counter (by silc_socket_dup) to prevent the bug that
602 the socket object may be freed underneath async operation.
604 * The name resolv library checking fixes in the configure.in.pre.
607 * Created new version of the protocol drafts for future
608 development. The -03 drafts are the ones that will be changed
609 in the trunk now and the -02 will remain as they are.
611 * Send list of CUMODE notifys to the router when announcing
612 the channel users to the router. Affected file silcd/server.c.
613 If the router receiving channel founder CUMODE for a channel
614 that already has channel founder it will send CUMODE notify
615 to the sender to remove the channel founder rights from the
616 announced client. Affected file silcd/packet_receive.c.
618 * The CUMODE notify may now use Server ID as well as the entity
619 who changes the mode. Updated protocool specs.
621 * Updated INSTALL and README files.
623 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
625 * New web pages in the http://silc.pspt.fi. The pages was
630 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
632 * Implemented the [DenyConnectin] config section in the server.
633 Added silc_server_config_denied_conn to check whether incoming
634 connection is denied. Affected file silcd/serverconfig.[ch].
636 * Do not check the ports when checking the incoming configuration
637 data if the port is 0, meaning any. Affected file is
638 silcd/serverconfig.c.
640 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
642 * Fixed buffer overflow in silc_string_compare in the file
643 lib/silcutil/silcutil.c.
645 * Fixed double free in silc_server_command_leave in the file
648 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
650 * Fixed the version checking in the server. Affected file is
653 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
655 * Fixed the configuration data fetching when accepting new
656 connections in the server. Affected file silcd/server.c.
658 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
660 * Added `sender_entry' argument to the function
661 silc_server_packet_relay_to_channel so that we can check
662 whether some destination actually belongs to the same route
663 the sender belongs (ie, we must not resend the packet to the
664 sender). Affected file silcd/packet_send.[ch].
666 * Added `servername' field to the SilcClientEntry in the server
667 to hold the name of the server where client is from. Affected
668 file is silcd/idlist.h.
670 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
672 * Moved the channel message encrypting in the router betwen
673 router connections from silc_server_channel_message to the
674 silc_server_packet_relay_to_channel since we want to check
675 whether we have anybody channel before encrypting anything.
676 Affected files silcd/packet_[receive/send].c.
678 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
680 * Fixed the [AdminConnection] server config section to support
681 multiple entries. Affected file silcd/serverconfig.c.
683 * Added support into the server to check the validity of the
684 incoming connection before executing any KE or authentication
687 * The connection configuration is now saved to the KE and
688 connection auth protocol contexts and not fetched anymore in
689 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
691 * The local hosts listenning address and port is also resolved
692 now when starting the server. We want to have the socket object
693 to include the real address and port for the listener. Added
694 new function silc_net_check_local_by_sock into the files
695 lib/silcutil/silcnet.[ch].
697 * Fixed a broadcast bug in server -> do not broadcast if we
700 * Fixed a routing bug. Do not route broadcast packets ever.
701 Broadcast packets must be processed always and not routed since
702 they may be destined to some other host than yourself and thus
703 would get routed without no good reason. Affected file is
706 * Added function silc_server_config_is_primary_route to check
707 whether primary router connection has been configured (a router
708 configuration that we are initiating). If there is not, we
709 will assume that there is only two routers in the SILC network
710 and we will use the incoming router connection as our primary
711 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
713 * Changed the order of the broadcasting. Broadcast _after_ the
714 packet has been processed not before. Affected file is
717 * Fixed a [ClientConnection] parsing bug. The port was never
718 parsed correctly thus resulting to port 0. Affected file
719 silcd/serverconfig.c.
721 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
722 argument and did not set the broadcast packet flag. Affected
723 file silcd/packet_send.c. Fixed same bug in the function
724 silc_server_send_notify as well.
726 * If we receive NEW_ID packet for our own ID in the server, ignore
729 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
733 * Removed the nickname from the Private Message Payload.
734 Updated the code and the protocol specs.
736 * Updated protocol specs for submitting to the IETF.
738 * Tweaked the Random Number Generator a bit. Affected file
739 lib/silccrypt/silcrng.c. Exported a new function
740 silc_rng_[global]_add_noise which can be used to add more
743 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
745 * Do not parse packets with different timeout when protocol
746 is active -> may cause problem with rekey. Affected file
749 * When server receives signoff notify it must not create
750 new channel key if the client is on any channels since the
751 sender of the signoff notify will create it.
753 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * Added printing of error messages during SKE protocol from the
756 failure packet sent by server during SKE. Affected file
759 * Removed the client's failure_callback handling with timeout
760 and handle it immediately when received.
762 * The SKE library returned wrong type in SUCCESS and FAILURE
763 packets. They must be 32 bit MSB not 16 bit MSB.
765 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
767 * Ok, rewrote the logic of the re-key and now it seems to work.
768 I tested it on high traffic with frequent re-keys without
769 problems. Added hmac_receive (and renamed hmac to hmac_send)
770 in SilcClientConnection in lib/silcclient/client.h and
771 in SilcIDListData in silcd/idlist.h. Also, removed the
772 SilcPacketParserContext's cipher and hmac fields as they are
773 not needed anymore and actually caused some problems when
774 the ciphers and hmac's changed underneath the packet parser.
776 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
778 * If re-key protocol is active then process the incoming packets
779 synchronously since we must assure that icoming packets encrypted
780 with the old key is processed before the new keys is set to
781 use. This is true other packets than for REKEY packets.
782 Affected file silcd/server.c. The same was done to client library
783 as well, affected file lib/silcclient/client.c.
785 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * Fixed bug in client and server to accept the force send if
788 the packet is send from silc_[server/client]_packet_process
789 function. Otherwise the packets are never delivered, oops.
791 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
793 * Disable force sending of packets when REKEY protocol is active.
794 We must assure that no packet is sent directly when rekey is
795 performed. All packets must be sent through packet queue.
796 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
797 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
798 function is silc_[server/client]_packet_send_real to check
801 * Replaced the SIM paths from example config files to
802 /usr/local/modules. Also, make install creates now
803 /usr/local/silc/logs directory to hold all the SILC server
806 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
808 * Made the configure.in.pre work on Solaris. Patch by salo.
810 * Made all ciphers compatible with non-x86 machines. Defined
811 CBC mode macros into lib/silccrypt/ciphers_def.h.
813 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
815 * Fixed the make install.
817 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
819 * When MAC computation fails the silc_packet_decrypt returned 0
820 even though it was supposed to return -1. Fixed this. The
821 affected file is lib/silccore/silcpacket.c.
823 * Do not replace the config files in /etc/silc (in make install)
824 if they already exist. Affected file ./Makefile.am.
826 * Do not send re-key packets immediately but through packet queue.
827 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
829 * Changed silc_net_check_host_by_sock to return FALSE if the
830 IP/DNS could not be resolved. Though, it returns the IP address
831 now even if it could not resolve it (but returns also FALSE).
832 Affected file lib/silcutil/silcnet.[ch].
834 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Added silc_pkcs_decode_identifier to decode the public key's
837 identifier. Affected file lib/silccrypt/silpkcs.[ch].
838 Added also silc_pkcs_free_identifier. Added also new context
839 SilcPublicKeyIdentifier.
841 * Added -S option to the silc client. It is used to dump the
842 contents of the specified public key file.
844 * Changed the PKCS api to return the public key length when
845 setting the public key.
847 * Fixed a fatal bug in the public and private key file loading.
848 Affected file lib/silccrypt/silcpkcs.c.
850 * Execute the packet parsing for client with zero (0) timeout
851 if the protocol is active. Affected file silcd/server.c.
853 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
855 * Made the key generation options to the silcd program. Added
856 -C option, equivalent to client's option.
858 * Added new [ServerKeys] config section to the server. It
859 configures the server's public and private key.
861 * Defined generic Public Key Payload into the protocol
862 specification to send specific type of public keys and
865 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
866 public key or certificate.
868 * Implemented the GETKEY command to the server and to the
869 client library and on user interface.
871 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
873 * Made preliminary `make install' work.
875 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
877 * Added SilcServerRekey context into silcd/idlist.h.
879 * Added the PFS support as defined in the specification to the
880 SKE protocol. Affected files lib/silcske/*.c.
882 * Added `ske_group' field to the SilcServerRekey context to hold
883 the number of the SKE group that is used with PFS in re-key.
884 Affected file silcd/idlist.h.
886 * Added PFS re-key support to the server. Affected file is
889 * Added silc_protocol_cancel to cancel execution of the next
890 state of the protocol. Affected file is
891 lib/silccore/silcprotocol.[ch].
893 * Added the re-key support with and without PFS to the client
894 library. Re-key is performed once in an hour, by default.
896 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
897 Added silc_client_rekey_callback and silc_client_rekey_final.
898 Affected files are lib/silcclient/protocol.[ch] and
899 lib/silcclient/client.[ch].
901 * Removed the `hmac_key' and `hmac_key_len' fields from the
902 SilcClientConnection structure; not needed. Affected file is
903 lib/silcclient/client.h.
907 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
909 * Do not ask whether user wants to use the negotiated private key
910 for private messages, just use it. Affected file is
911 silc/local_command.c.
913 * Added `send_enc_key' and `enc_key_len' fields to the
914 SilcIDListData structure since they are needed in the re-key
915 phase. Affected file is silcd/idlist.[ch].
917 * Implemented the simple re-key protocol into the server.
918 Affected files silcd/server.c and silcd/protocol.[ch]. The
919 re-key will be performed once in an hour, by default.
921 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
922 Added silc_server_rekey, silc_server_rekey_callback and
923 silc_server_rekey_final.
925 * Removed Tunneled flag from the protocol. Updated the code
926 and the specifications.
928 * Adde `pfs' field to the SilcIDListData to indicate whether
929 the PFS is to be performed in the re-key. Affected file is
932 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
934 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
935 int64 of at least the xintXX size. If void * is less that 4
936 bytes uint32 * will be used. Defined bool as boolean.
938 * Changed _ALL_ unsigned long and unsigned int to uint32,
939 unsgined short to uint16 in the source tree.
941 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
942 not handle clients that has entry->data.registered == FALSE.
943 They are not in the network anymore. Affected file is
946 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
948 * Implemented the sending of the SERVER_SIGNOFF notify in the
949 server. Affected file is silcd/server.c.
951 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
952 Added also silc_notify_payload_encode_args into the
953 lib/silccore/silcnotify.[ch].
955 * Implemented ther SERVER_SIGNOFF notify handling in the server.
956 Affected file silcd/packet_receive.c.
958 * Implemented the SERVER_SIGNOFF notify handling in the client
959 library. Affected file lib/silcclient/client_notify.c. Also,
960 implemnted the printing of the SERVER_SIGNOFF info to the
961 application. Affected file silc/client_ops.c.
963 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
964 if the deleting was successful. Affected file silcd/idlist.[ch].
966 * Added support for public key authentication in the connection
967 authentication protocol in the client library. Affected file
968 lib/silcclient/protocol.c.
970 * Changed the server's silc_idlist_get_clients_by_* interface
971 to support already allocated array so that new entries may be
972 added to pre-allocated array. Affected file silcd/idlist.[ch].
973 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
976 * All command reply functions in the server now calls the
977 pending command callback even if error occured. This way the
978 error will be delivered to the client as well. Affected files
979 silcd/command.c and silcd/command_reply.c.
981 * Fixed INFO command to return local server's info if no server
982 was provided. Affected file lib/silcclient/command.c.
984 * Removed RESTART command for good. Updated the code and the
987 * Rewrote parts of the task system. It is a bit simpler now.
988 Removed unsued task priorities. The affected files are
989 lib/silcutil/silctask.[ch].
991 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Moved the USERS printing from the library to the application.
994 Affected files lib/silcclient/command.c and silc/client_ops.c.
996 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1000 * Added channel key re-key support. The re-key is perfomed
1001 only by the router and is done once in an hour. Added `rekey'
1002 field to the SilcChannelEntry in the server. Affected files
1003 silcd/server.c and silcd/idlist.h.
1005 * Added silc_task_unregister_by_context into the file
1006 lib/silcutil/silctask.[ch].
1008 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Added SILC_UMODE_GONE mode to indicate when the client is not
1011 present in the SILC network. Added also support to the local
1012 command AWAY that will set this mode. Added support of showing
1013 "xxx is gone" in WHOIS command. The USERS command shows the
1014 gone status as well.
1016 * Fixed setting server and router operator privileges in the
1017 server's UMODE command. Affected file silcd/command.c.
1019 * Merged the SKE KE1 and KE2 payloads into one payload. The
1020 new KE payload is equivalent to the old KE2 payload.
1022 Cleaned up the SKE Start Payload parsing. It now uses the
1023 simple buffer unformatting to do the parsing. A lot faster
1026 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1027 to the SKE that is used to indicate whether both of the SKE
1028 parties should perform authentication. By default only the
1029 responder performs authentication. By setting this flag also
1030 the initiator must do authentication. By default it is unset
1031 since in normal SKE case, client to server connection, only
1032 the responder should do authentication. When doing SKE between
1033 two clients both should perform authentication. Updated the
1034 code and the protocol specs.
1036 * A little fix to IDENTIFY command in the server. Search the
1037 client first by hash not nickname. Affected file is
1040 * Fixed the silc_client_close_connection to support closing
1041 the client to client connections wihtout deleting too much
1042 data. Affected file lib/silcclient/client.c.
1044 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1045 are received if protocol used to be active but is not anymore
1046 the application would crash due to NULL pointer dereference.
1047 Affected files silcd/server.c and lib/silcclient/client.c.
1049 * Added `hash' field to the SilcClientConnection to include
1050 the hash function negotiated in the SKE protocol.
1052 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1053 to set the channel founder authentication data. A client can
1054 claim the founder rights later by providing the authentication
1055 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1056 This way the channel founder can regain the channel founder
1057 privileges even it is left the channel. This works only on
1058 local server and the client must be connected to the same
1059 server to be able to regain the founder rights. Updated the
1060 protocol specs accordingly.
1062 Added support to the CMODE command in the client to set the
1063 founder auth data. Read the README to see how to set it.
1065 Added support to the CUMODE command to claim the founder
1066 rights. Read the README to see how to do it.
1068 Added support for the founder authentication to the Channel
1069 Entry in the server. Affected file silcd/idlist.h.
1071 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1072 server's CMODE command. Affected file silcd/command.c.
1074 * Added the following new functions into lib/silccore/silcauth.[ch]:
1075 silc_auth_get_method and silc_auth_get_data.
1077 * The server now saves the remote hosts public key to the
1078 SilcIDListData pointer. Affected file silcd/protocol.c.
1080 * The normal server now does not remove the channel entry from
1081 the cache if the founder authentication data is set. It used
1082 to remove it if the founder was the last one on the channel on
1083 the server and left the channel. The auth data is saved and
1084 if the channel is re-joined later the old entry is used with
1085 the old auth data. Affected files silcd/command_reply.c and
1088 * Removed the `pkcs' field from the SilcIDListData structure
1089 in the server; it is not used. Affected file silcd/idlist.h.
1091 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1093 * Fixed packet processing on slow links. Partial packets were
1094 never re-processed because the incoming data buffer was cleared
1095 by the application. Application must not directly clear the
1096 sock->inbuf, the packet processing routines handle it. Fixed
1097 this in client library and in server.
1099 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * Fixed the WHOIS and IDENTIFY send reply function to really
1102 check whether to send list or just one entry. Affected file
1105 * Cleaned up the LEAVE command's channel key distribution. The
1106 affected file silcd/command.c.
1108 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1109 can enforce the channel mode as well. In that case the ID
1110 includes the ID of the server. The code now enforces the
1111 mode change if the router have different mode than the server.
1113 * The notify client operation with CMODE_CHANGE notify can now
1114 return NULL client_entry pointer if the CMODE was not changed
1115 by client. Application must check for this.
1117 * Added <Server ID> argument to INFO command to support server
1118 info fetching by Server ID.
1120 * Added silc_server_announce_get_channel_users to get assembled
1121 packets of channel users of the specified channel. Affected
1122 file silcd/server.[ch].
1124 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1125 was freed underneath the ID Cache.
1127 * Re-announce clients when the server received CHANNEL_CHANGE
1128 notify from the router. Affected file silcd/packet_send.c.
1130 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1132 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1133 crashed since it did not handle the fact that there is no cipher
1134 called "3" and didn't check the error condition. Now fixed.
1136 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1137 flag. It can be used to send message requests.
1139 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1141 * Implemented the RESTART command in the client.
1143 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1144 notice type messages. Added notice printing to the user
1147 * The channel keys are not re-generated if the channel's mode
1148 is PRIVKEY, ie private key on the channel exists. Affected
1149 files silcd/server.c and silcd/command.c.
1151 * Fixed a little bug in channel message delivery when channel
1152 private keys are set in the server. Affected file is
1153 silcd/packet_send.c.
1155 * Changed the setting on channel->on_channel = TRUE from the
1156 silc_client_save_channel_key to the JOIN command reply. The
1157 key payload is not received if the private channel key is set.
1158 Affected file lib/silcclient/command_reply.c and the
1159 lib/silcclient/client_channel.c.
1161 * When the CMODE_CHANGE notify is sent and the channel private
1162 key mode is removed the channel key must be re-generated in
1163 other cells as well. Added this support for the router in the
1164 silcd/packet_receive.c.
1166 * Added new local command NOTICE to send notice message on
1167 channel. Affected file silc/local_command.[ch].
1169 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1171 * Added new local command ME to the client. It is used to send
1172 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1173 some action. Affected file silc/local_command.[ch].
1175 * Changed channel_message and private_message client operations
1176 to deliver the message flags to the application. Added also
1177 the `flags' arguments to the silc_client_send_channel_message
1178 and silc_client_send_private_message functions. Affected file
1181 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1183 * Redefined the Private Message Payload to support private message
1184 keys and to support the new private message flags. Updated
1185 the protocol specs. Flags makes it possible to have for example
1186 CTCP style messages.
1188 * Added new type SilcPrivateMessagePayload and defined an API
1189 for it in the lib/silcclient/silcprivate.[ch].
1191 * Tested private message private keys successfully. Tested the
1192 private message key set, unset and list commands with the new
1195 * Redefined the Channel Message Payload to include the channel
1196 message flags (equal with private message flags) to support
1197 for example CTCP style messages.
1199 * Defined some of the message (for channel and private message)
1200 flags. Updated the protocol specs and added the flags to the
1201 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1203 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1205 * Added SilcKeyAgreementStatus type to the key agreement routines
1206 to indicate the current status and error if one occured.
1207 The status types are defined in the lib/silcclient/silcapi.h.
1209 * Added new local command KEY that is used to set and unset private
1210 keys for channels, set and unset private keys for private messages
1211 with remote clients and to send key agreement requests and
1212 negotiate the key agreement protocol with remote client. The
1213 key agreement is supported only to negotiate private message keys,
1214 it currently cannot be used to negotiate private keys for channels,
1215 as it is not convenient for that purpose.
1217 * Fixed a minor pending callback setting bug in the function
1218 silc_client_get_client_by_id_resolve, now the function works.
1219 Affected file lib/silcclient/idlist.c.
1221 * Added function silc_net_get_local_port to get local bound
1222 port by socket. Added to lib/silcutil/silcnet.[ch].
1224 * Added `sockets' and `sockets_count' fields to the SilcClient
1225 object. They hold the sockets of the listenning sockets in
1226 the client. Listenning sockets may be for example the key
1227 agreement server. Affected file lib/silcclient/client.[ch].
1228 Added functions the silc_client_add_socket and the
1229 silc_client_del_socket. They are exported to the application
1232 * Added ~./silc/clientkeys to support other client's public keys.
1234 * Renamed verify_server_key client operation to verify_public_key
1235 and added one argument to indicate the type of the connection
1236 (server, client etc.).
1238 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1240 * Added silc_server_connection_auth_request to handle the
1241 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1242 silcd/packet_receive.[ch].
1244 * Added silc_server_send_connection_auth_request into the
1245 silcd/packet_send.c to send the connection auth request packet.
1247 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1250 * Fixed the public key authentication in responder side in the
1251 server. The `auth_data' pointer includes the SilcPublicKey
1252 not the path to the public key. Affected file silcd/protocol.c.
1254 * Implemented the public key authentication in the initiator side
1255 in the server. Affected file silcd/protocol.c.
1257 * Removed the [RedirectClient] config section from the server
1258 configuration. Is not needed and I don't want to implement it.
1260 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Cleaned up the CMODE command in the server. It now works
1263 correctly and supports all the modes defined in the protocol.
1264 Affected file is silcd/command.c.
1266 * Added `hmac_name' field to the SilcChannelEntry in the server
1267 to hold the default HMAC of the channel. It can be set when
1268 creating the channel (with JOIN command). Affected files
1271 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1272 type to indicate the change of the current cipher and hmac
1273 on the channel. Client can safely ignore the <cipher> argument
1274 (if it chooses to do so) since the CHANNEL_KEY packet will
1275 force the channel key change anyway. The <hmac> argument is
1276 important since the client is responsible of setting the new
1277 HMAC and the hmac key into use.
1279 * Fixed the CMODE command in the client library as well.
1281 * Tested CMODE command in router environment successfully.
1283 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1285 * Show the version of the remote client (or server) when connecting
1286 to the server. It is logged to the log file. Affected file
1287 is silcd/protocol.c.
1289 * Fixed the KILLED notify handling in the client library. The
1290 client must be removed from all channels when receiving the
1293 Also, do not remove the client entry when giving the KILL
1294 command but when the KILLED notify is received.
1296 * Removed silc_idlist_find_client_by_nickname from the server.
1297 Not needed anymore. Affected files silcd/idlist.[ch].
1299 * Implemented the CHANNEL_CHANGE notify type handling to the
1300 server. Affected file silcd/server.c.
1304 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1306 * Added silc_server_send_notify_invite to send the INVITE
1307 notify between routers.
1309 * Implemented the INVITE command correctly to the server.
1311 * Implemented the INVITE notify type handling in the server.
1313 * Implemented the INVITE command to the client library and on the
1316 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1318 * Added function silc_server_get_client_resolve to find the
1319 client entry by ID from all ID lists and then resolve it
1320 (using WHOIS) if it cannot be found. Affected file is
1323 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1325 * Implemented the BAN command to the client library.
1327 * The JOIN command in the server now checks the invite list
1330 * Changed the silc_command_reply_payload_encode_va and the
1331 silc_command_payload_encode_va to support that if argument is
1332 NULL it ignores and checks the next argument. Affected file
1333 lib/silccore/silccommand.c.
1335 * Added silc_server_send_notify_ban to send the BAN notify
1336 type between routers.
1338 * Chaned the silc_notify_payload_encode to support that if
1339 argument is NULL it ignores and checks the next argument.
1340 Affected file lib/silccore/silcnotify.c.
1342 * Tested ban lists in router environment successfully.
1344 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1346 * Implemented BAN command to the server, in silcd/command.[ch].
1348 * Removed the BAN and INVITE_LIST modes from the CMODE command
1351 * Added function silc_string_match to regex match two strings.
1352 Affected files lib/silcutil/silcutil.[ch].
1354 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1356 * Redefined parts of the SilcChannelEntry in the server to support
1357 the new ban and invite lists.
1359 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1361 * Redefined the INVITE command. The same command can be used to
1362 invite individuals to the channel but also to manage the invite
1363 list of the channel (to add to and remove from the invite list).
1364 Updated the protocol specs.
1366 * Added new command SILC_COMMAND_BAN that can be used to manage
1367 the ban list of the channel. Updated the protocol specs.
1369 * Removed the channel modes: the SILC_CMODE_BAN and the
1370 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1371 in the CMODE command. The equivalent features are now available
1372 using INVITE and BAN commands. Updated the protocol specs.
1374 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1375 in the network about change in the current ban list. The notify
1376 type is not used by the client.
1378 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1379 support the invite lists.
1381 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Added new function silc_string_regexify that converts string
1384 including wildcard characters into regex string that can
1385 be used by the GNU regex library. Added into the file
1386 lib/silcutil/silcutil.[ch].
1388 Added silc_string_regex_combine to combine to regex strings
1389 into one so that they can be used as one regex string by
1390 the GNU regex library. Added into the file
1391 lib/silcutil/silcutil.[ch].
1393 Added silc_string_regex_match to match two strings. It returns
1394 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1396 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1398 * Imported GNU regex to the soruce tree into lib/contrib.
1399 Fixed some compiler warning from the regex.c.
1401 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1403 * Fixed MOTD command in the server to work in router environment.
1405 * Fixed the MOTD command in the client library to support
1406 the server argument in the command.
1408 * Added `nickname_len' argument to the silc_idlist_add_client
1409 in the server, as the `nickname' argument may be binary data
1412 * Added silc_idlist_get_channels to return all channels from
1415 * Implemented LIST command to the server. Affected file is
1418 * Implemented the LIST command to the client library and on the
1421 * Added [<user count>] argument to the LIST command reply.
1422 With private channels the user count is not shown.
1424 * Updated TODO and README.
1426 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * The client entry's data.registered must be TRUE even with
1429 global client entry on global client list. The data.registered
1430 is used to check whether the client is anymore in the network,
1431 for example with WHOWAS command so it must be valid.
1433 * Fixed the WHOWAS command in the server. It now actually works
1434 in router environment. Added function into silcd/command_reply.c
1435 silc_server_command_reply_whowas_save.
1437 * Added silc_idlist_purge function to the silcd/idlist.c
1438 to periodically purge the ID Cache.
1440 * Fixed INFO command in the server. It works now in router
1441 environment. Added <server name> argument to the INFO command
1442 reply. Updated the protocol specs.
1444 * Fixed minor bug in silc_idcache_purge to not purge if the
1445 expire value is zero.
1447 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1448 they were buggy because of the WHOWAS information.
1450 * Fixed local command MSG to handle the async resolving of
1451 the remote client properly. It used to fail the first MSG.
1452 Affected file silc/local_command.c.
1454 * Added `data_len' field to SilcIDCache context.
1456 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1458 * Update TODO. Todo in commands in the server.
1460 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1462 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1463 used by routers as broadcast packet to inform other routers
1464 about the changed user mode.
1466 Implemented the notify handling in the server. Affected file is
1467 silcd/packet_receive.c. Added the function
1468 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1470 * Added new generic Channel Payload and deprecated the New Channel
1471 Payload. The New Channel Payload is now the generic Channel
1474 * Added new argument `mode' to the silc_server_send_new_channel
1475 as it is required in the Channel Payload now.
1477 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1478 and created a new and real SilChannelPayload to represent the
1479 new generic Channel Payload. Implemented the encode/decode
1480 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1482 * Added silc_server_get_client_channel_list to return the list
1483 of channels the client has joined for WHOIS command reply.
1484 Affected file silcd/server.[ch].
1486 * Implemented the channel list sending in the WHOIS command reply
1487 in server and in the client.
1489 Implemented the channel list displaying on the user interface
1490 as well. Affected file silc/client_ops.c.
1492 * Added silc_channel_payload_parse_list to parse list of Channel
1493 Payloads. It returns SilcDList list of SilcChannelPayloads.
1494 Client for example can use this function to parse the list of
1495 channels it receives in the WHOIS command reply. The caller
1496 must free the list by calling silc_channel_payload_list_free.
1497 Affected files lib/silccore/silcchannel.[ch].
1499 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * Added one new argument <user mode> to the WHOIS command reply
1502 to return the mode of the user in SILC. Updated the protocol
1505 Implemented it to the server and client.
1507 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1509 * Fixed the mode printing on the user interface on joining.
1510 Affected file silc/client_ops.c.
1512 * Implemented the UMODE command and user modes in general to the
1513 client library and to the user interface.
1515 * Implemented the UMODE command to the server.
1517 * The server now sends UNKNOWN_COMMAND error status if client sends
1518 unknown command. Affected file silcd/command.c.
1520 * All server commands now handle the command identifier the right
1521 way when sending the command reply to the client. The client can
1522 use to identify the command replies with the identifier.
1524 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1526 * Added silc_server_get_client_route to resolve the route to
1527 the client indicated by the client ID. Affected file is
1530 * Added silc_server_relay_packet as general function to relay
1531 packet to arbitrary destination. This deprecates functions
1532 like _send_private_message_key, _relay_notify etc. Affected
1533 file is silcd/packet_send.[ch].
1535 Removed silc_server_send_key_agreement,
1536 silc_server_send_private_message_key and
1537 silc_server_packet_relay_notify functions from the file
1538 silcd/packet_send.[ch].
1542 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1543 server. Affected file silcd/packet_receive.[ch].
1545 * Implemented the KILL command to the client. Implemented the
1546 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1547 Affected files lib/silcclient/command[_reply].c and
1548 lib/silcclient/client_notify.c. Implemented the KILL notify
1549 printing in the user inteface.
1551 * Fixed a lot silc_parse_nick memory leaks from the client
1552 library in the file lib/silcclient/command.c.
1554 * Changed the silc_server_send_notify_on_channels's `sender'
1555 argument from SilcSocketConnection to SilcClientEntry to
1556 check the sender as entry and not as connection object and not
1557 to send to the client provided as argument. The affected file
1558 is silcd/packet_send.[ch].
1560 * The notify packets that are destined directly to the client used
1561 to not to be processed by the server. Now changed that and the
1562 server processes all notify packets. After relaying the packet
1563 to the client the notify packet is processed in the server.
1565 * The silc_server_free_client_data now checks whether there is
1566 pending outgoing traffic for the client and purges the data to
1567 the network before removing the client entry.
1569 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1571 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1572 an client is killed from the SILC Network. Updated the protocol
1575 Added new function silc_server_send_notify_killed to the
1576 silcd/packet_send.[ch].
1578 * Added function silc_server_packet_relay_notify to relay notify
1579 packets that are destined directly to a client. In this case
1580 the server does not process the notify packets but merely relays
1581 it to the client. Affected file silcd/packet_send.[ch].
1583 Added also silc_server_packet_process_relay_notify to check
1584 whereto relay the notify. Affected file is
1585 silcd/packet_receive.[ch].
1587 * Implemented the KILL command to the server.
1591 * Added the backup schema desgined last fall to the protocol
1592 specs for everyone to see. The specification is in the
1593 *-spec-xx.txt draft and the packet type definitions for the
1594 backup routers is in *-pp-xx.txt draft. Thusly, added also
1595 new packet type SILC_PACKET_CELL_ROUTERS.
1597 * A big security problem in the implementation discovered. The
1598 signoff of an client did not cause new channel key generation
1599 which it of course should've done. The channel keys must be
1600 always re-generated when client leaves (or signoffs) the channel.
1601 The silc_server_remove_from_channels funtion now handles
1602 the channel key re-generation.
1604 * Added `sender' argument to the silc_server_send_notify_on_channels
1605 to not to send the client provided as argument. Affected file
1606 silcd/packet_send.[ch].
1608 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Implemented OPER and SILCOPER commands into the server and
1613 * Added silc_auth_verify and silc_auth_verify_data to verify
1614 the authentication directly from the authentication payload.
1615 It supports verifying both passphrase and public key based
1616 authentication. Affected file lib/silccore/silcauth.[ch].
1618 * Added `hash' field to the SilcIDListData structure. It is the
1619 hash negotiated in the SKE protocol. Affected file is
1622 * Slight redesigning of the SilcAuthPayload handling routines.
1623 Do not send SilcPKCS but SilcPublicKey as argument.
1625 * Implemented the public key authentication support to the
1626 serverconfig. The public key is loaded from the provided path
1627 and saved as authentication data to void * pointer. Thus,
1628 changed the unsigned char *auth_data to void *auth_data;
1630 * Fixed SHUTDOWN command to send the reply before the server
1631 is shutdown. :) Affected file silcd/command.c.
1633 * Fixed fatal bug in CONNECT command. The hostname was invalid
1634 memory and server crashed. Affected file silcd/command.c.
1636 * Fixed fatal bug in CLOSE command. The server_entry became
1637 invalid but was referenced later in the command. Affected file
1640 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1642 * Fixed fatal bug in failure packet handling. Server ignored
1643 the failure and thus crashed when it came.
1647 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1649 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1650 that the command may be executed only once in (about) 2 seconds.
1651 The old SILC_CF_LAG flag is same but allows command bursts up
1652 to five before limiting.
1654 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1655 server code. Various commands now includes the CF_LAG_STRICT
1656 flag to disallow any kind of miss-use of the command.
1658 * Fixed the silc_buffer_unformat to not to allocate any data
1659 if the length of the data is zero. It used to allocate the
1660 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1662 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Changed the format of AdminConnection configuration section
1665 in the server. Added username of the admin to the format.
1666 Affected files silcd/serverconfig.[ch].
1668 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1669 to return admin configuration data by host, username and/or
1672 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1674 * Implemented WHOWAS command to the server. Added the functions:
1676 silc_server_command_whowas_parse,
1677 silc_server_command_whowas_send_reply,
1678 silc_server_command_whowas_from_client and
1679 silc_server_command_whowas_from_server
1681 * Added <Client ID> argument to the WHOWAS command reply. Updated
1682 the protocol specs accordingly.
1684 * Implemented WHOWAS command and command_reply to the client
1687 Implemented the WHOWAS printing on the user interface.
1689 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1691 * Added new argument to the WHOWAS command reply, the real name.
1692 It is an optional argument. Updated the protocol specs.
1694 * Added SilcIDCacheDestructor callback that is registered when
1695 the SilcIDCache is allocated. The callback is called when
1696 an cache entry in the ID Cache expires, or is purged from the
1697 cache. Added into lib/silccore/idcache.[ch].
1699 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1700 to destruct the client entries when the cache entry expires.
1701 Other ID Cache's in server and in the client library ignores
1704 * If the ID Cache entry's `expire' field is zero then the entry
1705 never expires. Added boolean `expire' argument to the
1706 silc_idcache_add function in the lib/silccore/idcache.[ch].
1707 If it is TRUE the default expiry value is used.
1709 * Added silc_server_free_client_data_timeout that is registered
1710 when client disconnects. By default for 5 minutes we preserve
1711 the client entry for history - for WHOWAS command.
1713 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Added support to the server to enforce that commands are not
1716 executed more than once in 2 seconds. If server receives
1717 commands from client more frequently, timeout is registered
1718 to process the commands. Affected file silcd/command.c.
1719 Added new function silc_server_command_process_timeout.
1721 * Changed NICK_NOTIFY handling in client library to check that
1722 if the client's nickname was changed, so there is no need to
1723 resolve anything from the server.
1725 * Removed error printing from the WHOIS and IDENTIFY commands.
1726 If error occurs then it is ignored silently in the client library.
1727 The application, however, may map the received error to
1728 human readable error string. The application currently maps
1729 the NO_SUCH_NICKNAME error to string.
1731 * Made the command status message public to the application. Moved
1732 them from lib/silcclient/command_reply.c to
1733 lib/silcclient/command_reply.h. The application can map the
1734 received command status to the string with the
1735 silc_client_command_status_message function.
1737 * Added check to the server to check that client's ID is same
1738 as the Source ID in the packet the client sent. They must
1741 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1743 * Added dist-bzip hook to the Makefile.am to make bzip2
1744 compressed distributions.
1746 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1748 * Server now enforces the maximum length for the nickname and
1749 the channel as protocol specification dictates. 128 bytes for
1750 nickname and 256 bytes for channel name.
1752 * Moved the WHOIS printing to the application. The client libary
1753 does not print out the WHOIS information anymore, the application
1754 must do it. Renamed silc_client_command_reply_whois_print to
1755 the silc_client_command_reply_whois_save.
1757 The client's idle time is also sent to the application now, and
1758 the idle is shown on screen.
1760 * Added silc_client_command_reply_identify_save to save the
1761 received IDENTIFY entries.
1763 * Do not check for channel private keys in message sending and
1764 reception if the channel does not have the PRIVKEY mode set.
1765 Affected file lib/silclient/client_channel.c.
1767 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1769 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1770 just surfaced after chaning the JOIN procedure.
1772 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1774 * Added silc_client_get_clients_by_list to get client entries
1775 from Client ID list, that is returned for example by JOIN
1776 and USERS command replies. The application should use this
1777 function for example when JOIN command reply is received to
1778 resolve the clients already on the channel (library does not
1779 do that anymore as USERS command reply is not used in the JOIN
1780 procedure anymore). Affected files lib/silcclient/silcapi.h and
1781 lib/silcclient/idlist.c.
1783 * JOIN command reply and USERS command reply returns now SilcBuffer
1784 pointers instead of unsigned char pointers when returning
1785 the client list and mode list.
1787 * Added <Client ID> argument to the JOIN command reply, mainly
1788 for the server to identify for which client the command was
1789 originally sent. Updated protocol specs accordingly.
1791 * Added SilcDlist private_key pointer to the SilcChannelEntry
1792 in the client to support the channel private keys. Affected
1793 file is lib/silcclient/idlist.h.
1795 * Added SilcChannelPrivateKey argument to the function
1796 silc_client_send_channel_message so that application can choose
1797 to use specific private ke if it wants to. If it is not provided,
1798 the normal channel key is used, unless private keys are set.
1799 In this case the first (key that was added first) is used
1800 as the encryption key.
1802 * Implemented the support for channel private key handling.
1803 Implemented the following functions:
1805 silc_client_add_channel_private_key,
1806 silc_client_del_channel_private_keys,
1807 silc_client_del_channel_private_key,
1808 silc_client_list_channel_private_keys and
1809 silc_client_free_channel_private_keys
1811 Affected file lib/silcclient/client_channel.c.
1813 * Added the support for the private keys in the channel message
1814 sending and encryption and in the message reception and
1815 decryption. Affected funtions are
1816 silc_client_send_channel_message and silc_client_channel_message.
1818 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1820 * Added SKE's key verify callback to the client library's
1821 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1823 * Removed the statement that server (or router) must send USERS
1824 command reply when joining to the channel so that the client
1825 knows who are on the channel. Instead, the client list and
1826 client's mode list is now sent in the JOIN command reply to the
1827 client who joined channel. This is better solution.
1829 * Added function silc_server_get_users_on_channel and function
1830 silc_server_save_users_on_channel to the silcd/server.[ch].
1832 * Removed function silc_server_command_send_users from the
1835 * Do not show topic on the client library anymore. The topic is
1836 sent in the command reply notify to the application and the
1837 application must show the topic now.
1839 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1841 * Added client searching by nickname hash into the IDENTIFY and
1842 WHOIS commands in the server as they were clearly missing from
1843 them. Affected file is silcd/command.c.
1845 * Fixed a bug in private message receiving in the client library.
1846 The remote ID was freed and it wasn't supposed, now it is
1849 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1851 * Minor fix to the channel payload; allocate the data area, as it
1852 needs to be of specific length.
1854 * If the key agreement port is zero then the operating
1855 system will define the bound port. Affected files are
1856 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1858 * Added new function silc_channel_payload_decrypt into the file
1859 lib/silccore/silcchannel.[ch].
1861 * Moved the channel message etc, check from silc_packet_decrypt
1862 to applications. The library calls now a generic
1863 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1864 when the packet is either normal or special. This was done to
1865 allow more wide range of checking that was not allowed when
1866 the code was in library. Now applications can do virtually any
1867 checks to the packet and return to the library the decision how
1868 the packet should be processed. Affected files are
1869 lib/silccore/silcpacket.[ch].
1871 Added silc_server_packet_decrypt_check to the server and
1872 silc_client_packet_decrypt_check to the client library.
1874 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1875 to send with specified source and destination information.
1877 * Channel message delivery between routers was broken after the
1878 channel key distribution was fixed earlier. The channel key
1879 was used be to distributed to other routers as well which is not
1880 allowed by the protocol. Now this is fixed and channel keys
1881 really are cell specific and the channel message delivery between
1882 routers comply with the protocol specification.
1884 * Fixed various commands in server to check also the global list
1885 for the channel entry and not just the local list. The affected
1886 file silcd/command.c.
1888 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Added assert()s to buffer formatting and unformatting routines
1891 to assert (if --enable-debug) when error occurs. Affected
1892 file: lib/silcutil/silcbuffmt.c.
1894 * Changed to auto-reconnect to check whether the remote host is
1895 router and register the re-connect timeout if it is. It used
1896 to check that whether we are normal server, but router must do
1897 auto-reconnect with another router as well. Affected file
1900 * Removed the [<key len>] option from CMODE command as the cipher
1901 name decides the key length, nowadays. See the defined ciphers
1902 from the protocol specification.
1904 * Added [<hmac>] option to the CMODE command to define the HMAC
1905 for the channel. Added SILC_CMODE_HMAC channel mode.
1907 * Added [<hmac>] option for the JOIN command so that user can
1908 select which HMAC is used to compute the MACs of the channel
1911 * Added Hmac field to the Channel Message Payload. The integrity
1912 of plaintext channel messages are now protected by computing
1913 MAC of the message and attaching the MAC to the payload. The
1914 MAC is encrypted. Now, it is clear that this causes some
1915 overhead to the size of the packet but rationale for this is that
1916 now the receiver can verify whether the channel message decrypted
1917 correctly and also when private keys are set for the channel the
1918 receiver can decrypt the packet with several keys and check from
1919 the MAC which key decrypted the message correctly.
1921 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1922 lib/silccrypt/silccipher.[ch].
1924 * Added silc_hash_len to return the digest length into the
1925 lib/silcrypt/silchash.[ch].
1927 * Rewrote parts of Silc Channel Payload interface in the
1928 lib/silccore/silcchannel.[ch]. The encode function now also
1929 encrypts the packet and parse function decrypts it.
1931 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1933 * Fixed a minor formatting bug in the SKE's key material processing.
1934 It actually might have processed the keys wrong way resulting
1937 * Redefined the mandatory HMAC algorithms and added new algorithms.
1938 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1939 and hmac-md5 truncated to 96 bits. The mandatory is now
1940 hmac-sha1-96. Rest are optional (including the one that used
1941 to be mandatory). Rationale for this is that the truncated HMAC
1942 length is sufficient from security point of view and can actually
1943 make the attack against the HMAC harder. Also, the truncated
1944 HMAC causes less overhead to the packets. See the RFC2104 for
1947 * Added new [hmac] configuration section. The SKE used to use
1948 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1949 is of course wrong. The official names that must be proposed in
1950 the SKE are the ones defined in the protocol specification
1951 (hmac-sha1-96 for example). The user can configure any hmac
1952 using any hash function configured in the [hash] section. At
1953 least, the mandatory must be configured.
1955 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1957 * Added HMAC list to the SKE proposal list. It has now both
1958 hash algorithm list and HMAC list. This makes the protocol
1959 incompatible with previous versions. The SKE now seems to work
1960 the way it is supposed to work, for the first time actually.
1962 * Defined plain Hash algorithms to the protocol specification.
1965 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1967 * Implemented support for key agreement packets into the server.
1968 Added functions silc_server_key_agreement and
1969 silc_server_send_key_agreement. Other than these functions,
1970 server has nothing to do with this packet.
1972 * Added support for private message key packets into the server.
1973 Added functions silc_server_private_message_key and
1974 silc_server_send_private_message_key.
1978 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1979 called in the protocol's final callback instead in the END
1980 protocol state. This makes a little more sense and in the same
1981 time in client we can use the same protocol routines for normal
1982 key exchange and to key agreement packet handling as well.
1984 * Added to both client's and server's KE protocol context the
1985 SilcSKEKeyMaterial pointer to save the key material. We will
1986 bring the key material to the protocol's final callback by doing
1987 this. The final callback must free the key material.
1989 * Added SKE's packet_send callback into client's KE protocol
1990 context so that the caller can choose what packet sending function
1991 is used. This way we can use different packet sending when
1992 doing normal SKE when doing key agreement packet handling (in
1993 the key agreement packet handling we do not want to encrypt
1996 * Implemented the responder side of the key agreement routines
1997 in the client. The client can now bind to specified port and
1998 accept incoming key negotiation. The key material is passed
1999 to the application after the protocol is over.
2001 * Implemented the processing of incoming Key Agreement packet
2002 in the client. Added function silc_client_key_agreement to
2005 * Implemented the intiator side of the key agreement routines
2006 in the client. The client can now initiate key agreement with
2007 another remote client. The key material is passed to the
2008 application after the protocol is over.
2010 * Created client_keyagr.c to include all the key agreement
2013 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2014 SILC_TASK_CALLBACK except that it is not static.
2016 * Created client_notify.c and moved the Notify packet handling
2017 from the client.[ch] into that file.
2019 * Created client_prvmsg.c and moved all private message and
2020 private message key routines from the client.[ch] into that file.
2022 * Create client_channel.c and moved all channel message and
2023 channel private key routines from the client.[ch] into that file.
2025 * Changed silc_client_get_client_by_id_resolve to resolve with
2026 WHOIS command instead of IDENTIFY command, in the file
2027 lib/silclient/idlist.c.
2029 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2031 * Implemented the SKE's responder side to the Client library.
2033 * When FAILURE is received to the protocol do not trust it
2034 blindly. Register a timeout to wait whether the remote closes
2035 the connection as it should do it, only after that process the
2036 actual failure. This was changed to both client and server.
2038 * Added client_internal.h to include some of the structures
2039 there instead of client.h in lib/silcclient/.
2041 * Added function silc_task_unregister_by_callback to unregister
2042 timeouts by the callback function.
2044 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2046 * Some "Incomplete WHOIS info" errors has been appearing on the
2047 log files. Took away the entry->userinfo check from WHOIS
2048 reply sending. The entry->userinfo is now " " if client did not
2049 provide one. I thought this was fixed earlier but something
2050 is wrong still. Let's see if the error still appears.
2052 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2054 * Fixed a minor bug in the login when the channel key is
2055 re-generated in the server. It used to generate the key in
2056 wrong order and thus caused problems in the channel traffic.
2058 * Fixed a minor bug in channel key distsribution after
2059 KICK command. The key was not sent to the router even though
2062 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Added silc_ske_process_key_material_data as generic routine
2065 to process any key material as the SILC protocol dictates. The
2066 function is used by the actual SKE library but can be used by
2067 applications as well. This relates to the private message keys
2068 and the channel private keys since they must be processed the
2069 same way the normal SILC session keys. The protocol dictates
2070 this. Affected files: lib/silcske/silcske.[ch].
2072 Added also silc_ske_free_key_material to free the
2073 SilcSKEKeyMaterial structure.
2075 * Defined silc_cipher_set_key function to set the key for
2076 cipher without using the object's method function. The affected
2077 files: lib/silccrypt/silccipher.[ch].
2079 * Implemented silc silc_client_add_private_message_key,
2080 silc_client_add_private_message_key_ske,
2081 silc_client_del_private_message_key,
2082 silc_client_list_private_message_keys and
2083 silc_client_free_private_message_keys functions in the
2086 Added functions silc_client_send_private_message_key to send
2087 the Private Message Key payload and silc_client_private_message_key
2088 to handle incoming Private Message Key payload.
2090 * Added Cipher field to the Private Message Key payload to set
2091 the cipher to be used. If ignored, the default cipher defined
2092 in the SILC protocol (aes-256-cbc) is used.
2094 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2096 * Removed lib/silcclient/ops.h file.
2098 Redefined parts of the SILC Client Library API. Created new
2099 file silcapi.h that deprecates the ops.h file and defines the
2100 published Client Library API. Defined also private message key
2101 API and channel private key API into the file.
2103 This is the file that the application must include from the
2104 SILC Client Library. Other files need not be included by
2105 the application anymore.
2107 * Added new key_agreement client operation callback and also
2108 defined the Key Agreement library API for the application.
2110 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2112 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2113 is used by clients to request key negotiation between another
2114 client in the SILC network. If the negotiation is started it
2115 is performed using the SKE protocol. The result of the
2116 negotiation, the secret key material, can be used for example
2117 as private message key.
2119 Implemented the Key Agreement payload into the files
2120 lib/silccore/silauth.[ch].
2122 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2124 * Redefined ciphers for the SILC protocol. Added some new ciphers
2125 and defined the key lengths for the algorithms. Changed the
2126 code accordingly. The default key length is now 256 bits.
2128 * Fixed SKE key distribution function silc_ske_process_key_material
2129 when the key length is more than 128 bits. The default key
2130 length in SILC is now 256 bits.
2132 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2133 to indicate unsupported algorithm.
2135 * Renamed rijndael.c to aes.c and all functions as well.
2137 * Fixed a long standing channel key setting bug in client library.
2138 Weird that it has never surfaced before.
2140 * Fixed bug in channel deletion. If the entire channel is removed
2141 then it must also delete the references of the channel entry
2142 from the client's channel list as the client's channel entry and
2143 the channel's client entry share same memory.
2145 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2147 * Implemented CONNECT and SHUTDOWN commands in the client.
2149 * Implemented CLOSE command to the client.
2151 * Added the function silc_idlist_find_server_by_name into the
2152 files silcd/idlist.[ch].
2154 Added the function silc_idlist_find_server_by_conn into the
2155 files silcd/idlist.[ch].
2157 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2159 * DIE command was renamed to SHUTDOWN. Updated the both code
2162 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2163 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2165 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2168 * Added function silc_server_create_connection function to create
2169 connection to remote router. My server implementation actually
2170 does not allow router to connect to normal server (it expects
2171 that normal server always initiates the connection to the router)
2172 so the CONNECT command is only good for connecting to another
2175 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2177 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2178 or some other client was kicked from the channel.
2180 Implemented the handling of the notify type to both client
2183 Implemented silc_server_send_notify_kicked to send the KICKED
2184 notify. It is used to send it to the server's primary router.
2186 * Implemented the KICK command into server and client.
2188 * Added `query' argument to the silc_idlist_get_client function
2189 to indicate whether to query the client from server or not if
2192 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2193 to indicate that the client is not channel founder.
2197 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2199 * Removed the rng context from SilcPacketContext structure and
2200 changed that the packet routine uses the Global RNG API.
2202 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2204 * Added support for quit message that client can "leave" on the
2205 channel when it quits the SILC. It is ditributed inside the
2206 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2208 Added silc_server_free_client_data that will take the
2209 signoff message as argument.
2211 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2213 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2215 * Updated parts of the protocol specification to keep it up
2218 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2220 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2221 payloads in one packet.
2223 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2224 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2225 use now the new List flag.
2227 * Also deprecated the following packet types: REPLACE_ID,
2228 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2230 * Added list support for Notify packet in server.
2232 * Added silc_server_send_notify_channel_change to send the
2233 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2234 the silc_server_send_replace_id.
2236 * Added silc_server_send_notify_nick_change to send the
2237 NICK_CHANGE notify type. Deprecates the function
2238 silc_server_send_replace_id.
2240 * Added silc_server_send_notify_join to send the JOIN notify type.
2241 Deprecates the function silc_server_send_new_channel_user.
2243 * Added silc_server_send_notify_leave to send LEAVE notify type.
2244 Deprecates the function silc_server_send_remove_channel_user.
2246 * Added silc_server_send_notify_cmode and
2247 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2248 types. Deprecates the silc_server_send_set_mode function.
2250 * Added SERVER_SIGNOFF notify type to indicate that server has
2251 quit. This means that all clients on the channel from that
2252 server will drop. This can be also used when netsplit happens.
2254 Deprecated REMOVE_ID packet type since it is not needed anymore
2257 Added silc_server_send_notify_server_signoff to send the
2258 SERVER_SIGNOFF notify type. Deprecates the function
2259 silc_server_send_remove_id.
2261 Added also silc_server_send_notify_signoff to send the
2262 SIGNOFF notify type.
2264 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2265 SILC protocol from this day on. Changed the protocol
2266 specification as well.
2268 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2269 notify type. It is used between routers to notify about
2270 topic changes on a channel.
2272 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2275 * Partly updated the protocol specification to comply with the
2276 changes now made. It is still though a bit outdated.
2278 * The JOIN notify type now takes one extra argument <Channel ID>.
2279 The packet used to be destined to the channel but now the
2280 JOIN type may be sent as list thus it is impossible to
2281 destine it to any specific channel. By adding this argument
2282 it is again possible.
2284 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2286 * Added CREDITS file. The CHANGES and CREDITS file will appear
2287 in the distribution as well.
2289 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2291 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2292 types in the server's silcd/packet_receive.c.
2294 * Implemented CMODE and CUMODE to work in router environment.
2296 * Fixed minor encoding and decoding buglet from the
2297 lib/silccore/silcmode.c.
2299 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2302 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2304 * Changed all SilcConfigServer* and silc_config_server* to
2305 SilcServerConfig* and silc_server_config*, respectively.
2308 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2310 * Associated the ID (client or server ID) to the Authentication
2311 Payload to avoid any possibility of forging. Updated the
2312 protocol specification and the code accordingly.
2314 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2316 * The RSA key length is now save to the RsaKey context in the
2317 key generation process in lib/silccrypt/rsa.c. The key length
2318 is now used to figure out the maximum size of the block allowed
2319 to be encrypted/signed.
2321 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2322 is equivalent to the silc_mp_mp2bin but does not allocate any
2325 * Changed silc_mp_mp2bin API to take length argument. If it is
2326 non-zero then the buffer is allocated that large. If zero, then
2327 the size is approximated using silc_mp_sizeinbase, which however
2330 * Created Global RNG API which is global RNG that application can
2331 initialize. After initializing, any routine anywhere in the
2332 code (including library) can use RNG without allocating a new
2333 RNG object. This was done to allow this sort of use of the
2334 RNG in code that has no chance to allocate RNG object. All
2335 applications currently allocate this and many routines in the
2336 library use this. Affected file lib/silccrypt/silcrng.[ch].
2338 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2339 it to use the Global RNG API.
2341 * Defined Authentication Payload into protocol specification that
2342 is used during SILC session to authenticate entities. It is
2343 used for example by client to authenticate itself to the server
2344 to obtain server operator privileges.
2346 Implemented this payload into the lib/silccore/silcauth.[ch].
2347 Implemented also routines for public key based authentication
2348 as the new protocol specification dictates.
2350 Moved definitions of different authentication methods from
2351 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2353 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2354 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2355 silc_pkcs_verify_with_hash functions into the file
2356 lib/silccrypt/silcpkcs.[ch].
2358 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2360 * The client entry's userinfo pointer must be always valid.
2361 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2362 will fail since it requires the userinfo. Now, the userinfo
2363 is allocated as "" if actual userinfo does not exist. Actually,
2364 it must exist and it is totally Ok to drop client connections
2365 that does not announce the userinfo. However, we will make
2366 this workaround for now.
2368 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2369 to return the remote port by socket.
2371 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2373 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2374 SILC_SERVER_PENDING_EXEC and added an new macro
2375 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2376 data or when error occurs while processing the pending command.
2378 Added new argument `destructor' into silc_server_command_pending
2379 and to the SilcServerCommandPending object. This destructor is
2380 now called after calling the pending callback or if error occurs
2381 immediately. If error occurs the actual pending callback won't
2382 be called at all - only the destructor. The destructor may be
2383 NULL if destructor is not needed.
2385 All this applies for client library code as well. Similar
2386 changes were made there as well for the pending commands.
2388 In the client, the application must now allocate the
2389 SilcClientCommandContext with the silc_client_command_alloc
2392 * Added reference counter to the SilcServerCommandContext. Added
2393 function silc_server_command_alloc and silc_server_command_dup
2396 Same type of functions added to the client library for the same
2399 * Removed the cmd_ident from IDListData away since it is now
2400 global for all connections. It is the command identifier used
2401 in command sending and with pending commands. The affected file
2404 * Added reference counter to the SilcSocketConnection objecet to
2405 indicate the usage count of the object. The object won't be
2406 freed untill the reference counter hits zero. Currently only
2407 server uses this, and client ignores it. The client must be
2408 set to use this too later. The affected files are
2409 lib/silccore/silcsockconn.[ch]. Added also the function
2410 silc_socket_dup to increase the reference counter.
2412 This was mainly added because it is possible that the socket
2413 is removed underneath of pending command or other async
2414 operation. Now it won't be free'd and proper DISCONNECTING
2415 flags, etc. can be set to avoid sending data to connection that
2416 is not valid anymore.
2418 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2419 the connection. After that it sets SILC_SET_DISCONNECTED.
2420 It is, however, possible that the socket data is not still freed.
2421 The silc_server_packet_process now checks that data is not
2422 read or written to connection that is DISCONNECTED. The socket
2423 get's freed when the reference counter hits zero.
2425 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2427 * Changed the client operation API: channel_message operation's
2428 `sender' is now the client entry of the sender, not the nickname
2429 and the `channel' is the channel entry, not the channel name.
2431 In the private_message operation the `sender' is now also the
2432 client entry of the sender not the nickname.
2434 Affected file is lib/silcclient/ops.h and all applications
2435 using the client operations.
2437 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2439 * Moved the calling of ops->connect() from connect_to_server_final
2440 into receive_new_id functin since that is the point when the
2441 client is actually allowed to send traffic to network. The
2442 affected file is lib/silcclient/client.c.
2444 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2447 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2448 (if needs broadcasting) instead of broadcasting the packets one
2449 by one which would make a burst in the network traffic.
2451 * Added `broadcast' argument to the functions in silcd/server.[ch]
2452 silc_server_create_new_channel[_with_id] to indicate whether
2453 to send New Channel packet to primary router.
2455 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2457 * Added new function into the silcd/server.[ch] files:
2458 silc_server_create_new_channel_with_id to create new channel with
2459 already existing Channel ID.
2461 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2462 lib/silccore/silcpacket.h. This packet is used t send list of
2463 Set Mode payloads inside one packet. Server uses this to set
2464 the modes for the channels and clients on those channels, that it
2465 announced to the router when it connected to it. The protocol
2466 specification has been updated accordingly.
2468 * The silc_server_new_channel did not handle the packet coming
2469 from normal server as it normally does not send that. However,
2470 when it announces its channels it does send it. Implemented
2471 the support for that.
2473 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2474 into the file lib/silccore/id.h.
2476 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Fixed memory leaks in the functions silc_idlist_del_client,
2479 silc_idlist_del_channel and silc_idlist_del_server in the file
2480 silcd/idlist.c. All of those leaked like a sieve.
2482 * Fixed some small memory leaks in the client's function
2483 silc_client_notify_by_server.
2485 * Added functions into silcd/server.c: silc_server_announce_clients,
2486 silc_server_announce_channels and silc_server_announce_server.
2487 These functions are used by normal and router server to announce
2488 to its primary router about clients, channels and servers (when
2489 router) that we own. This is done after we've connected to the
2492 These functions effectively implements the following packet types:
2493 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2494 and SILC_PACKET_NEW_ID_LIST.
2496 * Added new functions into the silcd/packet_receive.[ch]:
2497 silc_server_new_id_list, silc_server_new_channel_list and
2498 silc_server_new_channel_user_list to handle the incoming
2499 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2501 * Added support of changing Channel ID in the function
2502 silc_server_replace_id. If the server that announces a channel
2503 to the router already exists in the router (with same name but
2504 with different Channel ID), router is responsible to send
2505 Replace ID packet to the server and force the server to change
2506 the Channel ID to the one router has.
2508 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2509 client that the Channel ID has been changed by the router. The
2510 normal server sends this to the client. Client must start using
2511 the new Channel ID as the channel's ID.
2513 Implemented handling of this new type into lib/silcclient/client.c
2514 into the function silc_client_notify_by_server.
2516 * Added new function silc_idlist_replace_channel_id into the files
2517 silcd/idlist.[ch] to replace the Channel ID.
2519 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2521 * Call silc_server_command_identify_check always when processing
2522 the IDENTIFY command in silcd/command.c
2524 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2527 send keepalive packets. The packet can be sent by clients,
2528 servers and routers.
2530 Added function silc_socket_set_heartbeat into the file
2531 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2532 If not set, the heartbeat is not performed. The actual
2533 heartbeat is implemented in the low level socket connection
2534 library. However, application is responsible of actually
2537 Added silc_server_send_heartbeat to send the actual heartbeat
2538 packet into silcd/packet_send.[ch]. Server now performs
2539 keepalive with all connections.
2541 * Added silc_task_get_first function into lib/silcutil/silctask.c
2542 to return the timeout task with shortest timeout. There was a bug
2543 in task unregistration that caused problems. TODO has been
2544 updated to include that task system must be rewritten.
2546 * The client library will now resolve the client information when
2547 receiving JOIN notify from server for client that we know but
2548 have incomplete information.
2550 * Rewrote parts of silc_server_remove_from_channels and
2551 silc_server_remove_from_one_channel as they did not remove the
2552 channel in some circumstances even though they should've.
2554 * Encryption problem encountered in server:
2556 The LEAVE command used to send the Channel Key packet to the
2557 router immediately after generating it. However, the code
2558 had earlier sent Remove Channel user packet but not immediately,
2559 ie. it was put to queue. The order of packets in the router
2560 was that Channel Key packet was first and Remove Channel User
2561 packet was second, even though they were encrypted in the
2562 reverse order. For this reason, MAC check failed. Now, this
2563 is fixed by not sending the Channel Key packet immediately but
2564 putting it to queue. However, this is more fundamental problem:
2565 packets that are in queue should actually not be encrypted
2566 because packets that are sent immediately gets encrypted
2567 actually with wrong IV (and thus MAC check fails). So, packets
2568 that are in queue should be encrypted when they are sent to
2569 the wire and not when they put to the queue.
2571 However, the problem is that the current system has not been
2572 designed to work that way. Instead, the packet is encrypted
2573 as soon as possible and left to the queue. The queue is then
2574 just purged into wire. There won't be any fixes for this
2575 any time soon. So, the current semantic for packet sending
2578 o If you send packet to remote host and do not force the send
2579 (the packet will be in queue) then all subsequent packets to the
2580 same remote host must also be put to the queue. Only after the
2581 queue has been purged is it safe again to force the packet
2584 o If you send all packets immediately then it safe to send
2585 any of subsequent packets through the queue, however, after
2586 the first packet is put to queue then any subsequent packets
2587 must also be put to the queue.
2589 Follow these rules and everything works fine.
2591 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Added new function silc_server_remove_clients_by_server to
2594 remove all client entries from ID list when the server connection
2595 is lost. In this case it is also important to invalidate all
2596 client entires as they hold the invalid server entry. This
2597 fixes fatal bug when server has lost connection and will reconnect
2600 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * Made some sanity checks to silc_server_daemonise like to check
2603 whether the requested user and group actually exists.
2605 * Added sanity check to SKE's silc_ske_responder_finish to check
2606 that the public and private key actually is valid.
2608 * Invalidate the client's nickname when receiving Replace ID
2609 packet and the Client ID is being replaced. This means that the
2610 server will query the nickname if someone needs it (client)
2613 * Sort the ID Cache in client library when the ID Cache data
2614 has changed (needs sorting).
2616 * Do not allow for SILC client to create several connections to
2617 several servers. The client does not support windows right now
2618 and generating multiple connections causes weird behaviour.
2620 Irssi-silc client does support windows and can handle several
2621 connections without problems, see: www.irssi.org and SILC plugin.
2623 * Fixed some places where client was added to the IDList. The
2624 rule of thumb is following (in order to get everything right):
2625 If the client is directly connected local client then the
2626 `connection' argument must be set and `router' argument must be
2627 NULL to silc_idlist_add_client function. If the client is not
2628 directly connected client then the `router' argument must
2629 bet set and the `connection' argument must be NULL to the
2630 silc_idlist_add_client function.
2632 * The funtion silc_server_packet_send_local_channel actually did
2633 not check whether the client was locally connected or not. It
2634 does that now. Fixed a bug related to LEAVE command.
2636 * Fixed Remove Channel User payload parsing bug in server's
2637 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2639 * The server's silc_server_save_channel_key now checks also the
2640 global ID list for the channel as it might not be in the local
2641 list. Fixed a bug related to LEAVE command.
2643 * Is this the end of the [<unknown>] buglet that has been lurking
2644 around for a long time? A little for loop fix in server's
2645 silc_server_command_whois_parse that is used by both IDENTIFY
2646 and WHOIS command. At least, this was a clear bug and a cause
2647 of one type of [<unknown>] buglet.
2649 * WHOIS and IDENTIFY commands call the function
2650 silc_server_command_[whois/identify]_check function even if
2651 we are not router server.
2653 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Added --with-gmp configuration option. If set the GMP
2656 is always compiled in the SILC source tree. If not set then
2657 it is checked whether the system has the GMP3 installed. If
2658 it has then the GMP won't be compiled (the system's headers
2659 and library is used), if it doesn't have it then the GMP is
2660 compiled in the SILC source tree.
2662 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Changed RSA private exponent generation to what PKCS #1
2665 suggests. We try to find the smallest possible d by doing
2666 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2667 not security fix but optimization.
2669 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2671 * Added new config entry [Identity] to fork the server and run
2672 it as specific user and group. A patch from Bostik.
2674 * Imported Dotconf configuration library into lib/dotconf.
2675 This will be used to create the SILC configuration files later.
2676 It will appear in the distsribution after this commit.
2678 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2680 * A big code auditing weekend happening. Auditing code for
2681 obvious mistakes, bugs and errors. Also, removing any code
2684 Removed files for being obsolete:
2686 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2687 inline in the file lib/silcutil/silcbuffer.h)
2689 o lib/silcutil/silcbufutil.c (the header has inline versions)
2691 Changed code to fix possible error conditions:
2693 o The buffer formatting routines now check that the destination
2694 buffer really has enough space to add the data. This applies for
2695 both buffer formatting and unformatting
2696 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2697 unformatting was changed to accomodate following rules:
2698 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2699 sent to the function while XXX_*STRING will not allocate or copy
2700 the data into the buffer. Instead it sets the pointer from the
2701 buffer into the pointer sent as argument (XXX_*STRING used to
2702 require that the pointer must be allocated already). This change
2703 makes this whole thing a bit more consistent and more optimized
2704 (note that the data returned in the unformatting with XXX_*STRING
2705 must not be freed now). The routines return now -1 on error.
2707 o Tried to find all code that use buffer_format and buffer_unformat
2708 and added return value checking to prevent formatting and
2709 especially unformatting errors and possible subsequent fatal
2712 o Changed ske->x and ske->KEY to mallocated pointers in
2713 lib/silcske/silcske.h. Fixed possible data and memory leak.
2715 o Added return value checking to all *_parse* functions. Fixed
2716 many memory leaks as well.
2718 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2719 so that buffer overflows would not happen. All code now also
2720 checks the return value as it can fail.
2722 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2724 * Added reconnection support to server if the normal server looses
2725 its connection to the router (for example if router is rebooted).
2726 The server performs normal reconnection strategy implemented
2727 to the server. Affected file silcd/server.c.
2729 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * Added new packet type SILC_PACKET_SET_MODE that is used to
2732 distribute the information about changed modes (for clients,
2733 channels and clients channel modes) to all routers in the
2734 network. Updated the protocol specification accordingly.
2736 Added functions into silcd/packet_send.c and
2737 silcd/packet_receive.c: silc_server_send_set_mode,
2738 silc_server_set_mode.
2740 Added new files silcmode.[ch] into lib/silccore that implements
2741 the encoding and decoding of Set Mode Payload. Added new type
2742 SilcSetModePayload. Moved the definitions of different modes
2743 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2745 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * Oops, a little mistake in server's connection authentication
2748 protocol. The protocol is not ended with FAILURE but with
2749 SUCCESS if the authentication is Ok. :) Affected file is
2752 * Implemented NICK_CHANGE notify handling in server in the file
2753 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2754 the local clients on the channel. After the changing nickname
2755 in router environment snhould work and the [<unknown>] nickname
2756 should appear no more.
2758 The silc_server_replace_id function that receives the Replace ID
2759 payload now sends the NICK_CHANGE notify type also in the file
2760 silcd/packet_receive.c
2762 * Changed WHOIS and IDENTIFY command to support the maximum amount
2763 of arguments defined in protocol specs (3328 arguments). This
2764 fixed a bug that caused problems when there were more than three
2767 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Added extra parameter, command identifier, to the
2770 silc_client_send_command so that explicit command identifier
2773 Changed that ID list routines uses specific command identifier
2774 when sending WHOIS/IDENTIFY requests to the server so that they
2775 can be identified when the reply comes back.
2777 Affected files lib/silcclient/command.[ch],
2778 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2780 * Added `sender' argument to silc_server_packet_send_to_channel
2781 to indicaet the sender who originally sent the packet to us
2782 that we are now re-sending. Ignored if NULL. Affected file
2783 silcd/packet_send.[ch].
2785 * Added some server statistics support in silcd/server_internal.h
2786 SilcServerStatistics structure and around the server code. Also
2787 send some nice statistics information when client is connecting
2790 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2792 * Fixed channel ID decoding in server's JOIN command reply in
2793 silcd/command_reply.c
2795 * Fixed braodcasting of replace ID payload to not to send it if
2796 we are standalone server in silcd/packet_receive.c.
2798 * Fixed all channel message sending routines to not to send
2799 packets to clients that has router set, since they are routed
2800 separately in the same function earlier. Affects file
2801 silcd/packet_send.c and all channel packet sending functions.
2803 * In USERS reply, res_argv[i] are not allocated, the table
2804 is allocated. Thus changed that free the table, not its
2807 * In server's whois_check and identify_check if the client is
2808 locally connected do not send any WHOIS commands - they are not
2811 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2813 * Fixed some minor bugs in client when sending WHOIS command. The
2814 arguments was in wrong order.
2816 * Removed statis function add_to_channel from server in
2817 silcd/command.c that was previously used with the joining but
2820 * Tested USERS command in router environment successfully with two
2821 routers, two servers and two clients.
2823 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2825 * Reorganized the USERS command and command reply in client library
2826 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2827 When the command is given by user we register a pending command
2828 callback that will reprocess the command after the reply has been
2829 received from the server. When reprocessing the packet we then
2830 display the information. Thus, the USERS information is displayed
2831 now in the command callback instead of in the command reply
2832 callback. The processing of the command is same as previously
2833 when server has sent the command reply in the JOINing process.
2835 * Added to USERS command in silcd/command_reply.c to join the client,
2836 we didn't use to know about, to the channel after we've created
2837 a client entry for it. Also, for clienet we did know already still
2838 check whether it is on the channel or not and add it if not.
2840 * Removed silc_server_command_join_notify as the function and its
2843 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2845 * Changed the client's pending command handling to the same as the
2846 server's pending command handling. It is also now possible to
2847 execute command reply functions from other command reply
2848 function as the function callbacks for commands and command
2849 replies are one and same. The pending commands are not static
2850 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2851 in client connection context. Thus, pending commands are server
2852 connection specific as it is convenient.
2854 Changed the function silc_client_command_pending and
2855 silc_client_command_pending_del and added new function
2856 silc_client_command_pending_check. Removed the
2857 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2860 * Added cmd_ident, current command identifier, to the client
2861 connection context in lib/silcclient/client.h to keep track on
2862 command identifiers used in command sending. Client's command reply
2863 function handling now supports the mandatory command identifiers.
2865 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2866 funtions in client to fully support pending command callbacks.
2868 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2869 as one of the arguments to the application in the command reply
2872 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2873 before first releasing SILC but came back. Now it is removed again
2874 and should come back nomore. The FORWARDED flag was used only
2875 by the JOINing procedure by forwarding the command packet to router.
2876 Now, the JOINing procedure has been changed to more generic (due
2877 to various router environment issues) and FORWARDED is not needed
2878 anymore for anything. The protocol specification is yet to be
2881 Now, removed silc_server_packet_forward from server and the flag
2882 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2884 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Renamed NAMES command to USERS command. The NAMES was named that
2887 due to historical reasons. Now it is renamed. Also, rewrote
2888 parts of the USERS command. The nickname list is not sent anymore
2889 by the server. Only Client ID and mode lists are sent in the USERS
2890 command. Changed this also to the protocol specification.
2892 The client now resolves the names and stuff after it receives
2893 the USERS list from the server when joining to the channel.
2895 * WHOIS and IDENTIFY commands has been changed to support multiple
2896 Client ID's per command. One can now search for multiple users
2897 in the network by sending only one WHOIS or IDENTIFY command.
2898 Changed the code and the protocol specifications.
2900 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2901 uses silc_server_command_whois_parse to parse the request. */
2903 * If normal server, do not parse the WHOIS and IDENTIFY requests
2904 before sending it to the router. Saves some time.
2906 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Fixed JOIN command on client library. Wrong number of arguments
2909 used to crash the client.
2911 * Added silc_server_channel_has_global function to check whether
2912 channel has global users or not.
2914 * Added silc_server_channel_has_local function to check whether channel
2915 has locally connected clients on the channel.
2917 * The silc_server_remove_from_one_channel now checks whether the
2918 channel has global users or not after given client was removed from
2919 the channel. It also checks whether the channel has local clients
2920 on the channel anymore. If it does not have then the channel entry
2921 is removed as it is not needed anymore.
2923 * The silc_server_notify now checks on JOIN notify whether the joining
2924 client is one of locally connected or global. If it is global then
2925 the channel has now global users on the channel and that is marked
2926 to the channel entry. Also, it now saves the global client to
2927 global list who is joining and JOINs it to the channel. This is
2928 for normal server, that is.
2930 Changed silc_server_send_notify_on_channel,
2931 silc_server_packet_relay_to_channel and
2932 silc_server_packet_send_to_channel check if we are normal server
2933 and client has router set (ie. global client) do not send the
2934 message to that client, as it is already routed to our router.
2936 * Implemented LEAVE notify type handling in silc_server_notify
2939 * Tested LEAVE command in router environment successfully. Tested
2940 with two routers, two servers and two clients.
2944 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2946 * Implemented SIGNOFF notify type handling in silc_server_notify
2949 * silc_server_remove_id now removes the client entry from all channels
2950 it has joined and thusly sends SIGNOFF notify type.
2952 * Rewrote the NAMES list generation in server by removing two excess
2953 loops. The lists are created now inside one loop.
2955 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * silc_server_remove_channel_user checks now also global list
2958 for channel and client.
2960 * silc_server_new_channel_user checks now both local and global
2961 list for channel and client. Fixed a bug in client id decoding.
2962 Used to decode wrong buffer.
2964 * silc_server_channel_message checks now both local and global
2965 list for channel entry.
2967 * Tested channel joining (hence JOIN) in router environment
2968 successfully. Tested with two routers, two servers and two
2971 * Tested channel message sending in router environment successfully.
2973 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Added silc_server_save_channel_key into server.[ch] to save the
2976 received channel key in Channel Key payload processing. It is
2977 also used in JOIN command reply handling.
2979 Equivalent function silc_client_save_channel_key added into
2980 client.[ch] into client library.
2982 * Changed JOIN command reply to send information whether the channel
2983 was created or not (is existing already) and the channel key
2984 payload. Changed protocol specs accordingly.
2986 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2987 the request was sent by ID and not by nickname. Crashed on
2990 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2993 now correctly save the received data.
2995 * silc_server_free_sock_user_data now notifies routers in the
2996 network about entities leaving the network.
2998 At the same time implemented functions silc_server_remove_id
2999 and silc_server_send_remove_id to receive and send REMOVE_ID
3000 packets. The packet is used to notify routers in the network
3001 about leaving entities. The ID removed will become invalid in
3004 * Added function silc_idlist_del_server into server. Removes and
3005 free's server entry from ID list.
3007 * silc_server_private_message function now checks, if we are router,
3008 that the destination ID really is valid ID, naturally.
3010 * In router when NEW_ID packet is received (for new client) the
3011 hash of the Client ID is saved in the ID Cache but the
3012 client->nickname is set to NULL, instead of putting the hash
3015 IDENTIFY command now also checks that client->nickname must be
3016 valid. If it is not if will request the data from the server who
3017 owns the client. Added new function
3018 silc_server_command_identify_check.
3020 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3021 to set the command to already allocated Command Payload.
3023 * Tested private message sending in router environment with two
3024 routers, two servers and two clients. Fixed minor bugs and now
3027 * Fixed segfault from client's NAMES command. Used to crash if
3030 * Forwarded packets must not be routed even if it is not destined
3031 to the receiver. Changed server code comply with this.
3033 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Added `require_reverse_mapping' boolean value to ServerParams
3036 structure. If TRUE (not default) the server will require that
3037 the connecting host has fully qualified domain name.
3039 If the reverse mapping is not required and hostname could not be
3040 found the IP address is used as hostname.
3042 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * Implemented version string checking to both client and server.
3045 The check is incomplete currently due to the abnormal version
3046 strings used in development version of SILC.
3048 * Changed all command functions in server to use the new
3051 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3053 * Changed char *data to unsigned char *data in ID Cache system to
3054 support binary data as ID Cache data. Changed code to support
3055 binary data in lib/silccore/idcache.c.
3057 * Renamed silc_server_packet_relay_command_reply to
3058 silc_server_command_reply as it is normal packet receiving
3059 function. Rewrote the function to accept command replys for
3060 servers and not only for clients.
3062 * Mark remote router always as registered server if we are connecting
3063 to it. Otherwise, commands sent by the router to us are ignored.
3065 * All ID List find routines now returns the ID Cache Entry pointer
3066 as well if requested.
3068 * WHOIS command works now in router environment, tested with two
3069 routers, two servers and two clients.
3071 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3072 in router environment (as it is almost equivalent to WHOIS) but
3073 hasn't been tested thoroughly. Added new functions:
3075 silc_server_command_identify_parse
3076 silc_server_command_identify_send_reply
3077 silc_server_command_identify_from_client
3078 silc_server_command_identify_from_server
3080 * Disabled route cache adding because adding two different ID's with
3081 same IP replaces the old cache entry thus giving wrong route.
3082 The entry->router->connection is always the fastest route anyway
3083 so route cache may not be needed. Of course, new routes maybe
3084 established after receiving the ID when the entry->router->connection
3085 might not be anymore the most optimal.
3087 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3089 * Add route cache for received ID for fast routing.
3091 * Added silc_server_packet_route to route received packet on router
3092 that is not destined to us.
3094 * Renamed silc_server_get_route to silc_server_route_get.
3096 * Added id_string and id_string_len fields into SilcServer to
3097 include encoded ServerID for fast comparing without excess
3098 encoding of the ID's.
3100 * Cleaned up WHOIS command on server side. Added following static
3103 silc_server_command_whois_parse
3104 silc_server_command_whois_check
3105 silc_server_command_whois_send_reply
3106 silc_server_command_whois_from_client
3107 silc_server_command_whois_from_server
3109 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3110 arguments in command replies. All command functions should be
3111 updated to use this macro.
3113 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * Minor typo fixes on command reply handling on server.
3117 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Added silc_server_command_add_to_channel internal routine to add
3120 the client to the channel after router has created the channel and
3121 sent command reply to the server.
3123 * Added generic silc_server_send_command to send any command from
3126 * Use static buffer with ID rendering instead of duplicating data.
3128 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3130 * Fixed a channel user mode bug when joining to a channel server gave
3131 everybody channel founder rights, oops.
3133 * We mark ourselves as the router of the incoming server connection
3134 if we are router ourselves. This way we can check in some packet
3135 sending functions whether it is locally connected server. For
3136 incoming router connections we put NULL.
3138 * For router sending packets locally means now always sending the
3139 packet cell wide; to local clients and local servers. For normal
3140 server sending packet locally means sending it to only local
3143 * Fixed the JOIN command to really work in router environment. If the
3144 channel is created it is always created by the router. Router is
3145 also responsible of making the initial joining to the channel,
3146 sending JOIN notify to the sending server and distributing
3147 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3148 does not exist server doesn't do anything else but forward the
3149 command to the router which performs everything.
3151 * Added silc_server_send_channel_key function to send the Channel Key
3154 * Added silc_server_create_channel_key to create new channel key. The
3155 channel key is now re-generated everytime someone joins or leaves
3156 a channel, as protocol dictates. Note: channel->key_len is the
3159 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3162 packet_receive.[ch] to separate packet sending and receiving
3163 routines. The server.[ch] now includes everything else including
3164 actual packet processing (writing and reading data) and other
3167 Renamed silc_server_private_message_send_internal to
3168 silc_server_send_private_message. The routine is still though
3169 used only to relay private messages as server does not send
3170 private messages itself.
3172 Renamed silc_server_new_channel to silc_server_create_new_channel
3173 and added new function sicl_server_new_channel that handles the
3174 incoming New Channel packet. Added also new sending function
3175 silc_server_send_new_channel to send New Channel Payload.
3177 * Added new function silc_server_notify to process incoming notify
3178 packet to the server/router. Server may then relay the notify
3179 to clients if needed.
3181 * Added new function silc_server_new_channel_user to process incoming
3182 New Channel User packet. Router will redistribute the packet and
3183 send JOIN notify to its local clients and locally connected servers
3184 if needed. Normal server will send JOIN notify to its local client
3185 on same channel when received this packet. Added also corresponding
3186 sending function silc_server_send_new_channel_user to sent the
3189 * Added boolean route argument to send_notif_to_channel and
3190 packet_send_to_channel functions to attempt to route the packet
3191 if it is TRUE and send only locally if it is FALSE.
3193 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * silc_server_replace_id now broadcasts the received replace ID
3196 packet if it is not broadcast packet already. The router must
3197 broadcast to inform other routers about changed ID.
3199 * Added backpointer to server's router into SilcServer context in
3200 silcd/server_internal.h.
3202 * Fixed silc_server_packet_broadcast to send correct broadcast
3205 * The channel key is now distributed to the local client as soon
3206 as it is received from the router (in router environment) so that
3207 no other packet may be sent for the channel until client has
3210 * silc_server_remove_channel_user now broadcasts the received
3211 Remove Channel User packet if it is not broadcast packet already.
3212 The router must broadcast to inform other routers about removed
3215 * Added users field into SilcPacketContext that is a reference count
3216 of the context. One can increase the reference count by calling
3217 silc_packet_context_dup which is now changed to just increase the
3218 reference count instead of duplicating the data. The reference
3219 count is decresed by calling silc_packet_context_free that will
3220 free the data after the reference count hits zero.
3222 For now on the packet context and everything allocated into it
3223 (including the raw packet from network) must be freed by calling
3224 the new silc_packet_context_free function. Added also new function
3225 silc_packet_context_alloc that must be used now to allocate the
3226 context. This also means that if a routine is asynchronous from
3227 silc_[client/server]_packet_parse_type the packet context must
3228 be duplicated by calling silc_packet_context_dup. Otherwise it
3229 gets free'd after silc_[client/server]_packet_parse_type returns.
3230 Also, one must remember that if packet is duplicated then its
3231 reference count must be decresed by calling the free function as
3232 many times as it was duplicated.
3234 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3235 from both client and server.
3237 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Made joining to a channel working in router environment.
3241 * Cleaned up JOIN command on server side and create function
3242 silc_server_command_join_channel internal routine to make the
3245 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Changed silc_command_pending list to SilcDList. Also, added
3248 `ident' field to SilcServerCommandPending structure to identify
3249 the reply and to call correct callback.
3251 Added silc_server_command_pending_check function to replace the
3252 corresnponding macro. The silc_command_pending list is not
3255 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3256 to set identifier to previously allocated Command Payload. It
3257 is used to set identifier for command when resending Command
3260 * Added silc_command_payload_encode_payload to encode Command
3261 Payload buffer from SilcCommandPayload structure.
3263 * Added silc_argument_payload_encode_payload to encode Argument
3264 payload buffer from SilcArgumentPayload structure.
3266 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Changed WHOIS command to support router connection on server side.
3269 The whois request is always sent to router unless the server is
3270 standalone server. After server has received the reply from the
3271 router will it send the reply to the client.
3273 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3274 broadcast received broadcast packet. The function is used only
3275 by router. The broadcast packet is always sent to the router's
3278 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3279 render given ID to printable string, for log files for example.
3281 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3283 * Made basic router to router connections working. At least they
3284 can now connect to each other but nothing really works the way
3285 they are supposed - yet.
3287 * Added new initiator token to RouterConnection configuration
3288 file in silcd/serverconfig.[ch]. It is used to tell whether we
3289 are the initiator to the remote router or whether we'll expect
3290 the other end to connect.
3292 * Moved registering of listener task to silc_server_init, hence
3293 the server starts listenning as soon as it is run, even if it
3294 does not have connections to other routers. Let's see how well
3297 * Changed default connection retry timeouts for more suitable in
3300 * Removed cipher and such arguments from silc_idlist_add_client
3301 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3302 Added new function silc_idlist_add_data to add the keys and stuff
3305 * Added SilcIDListData structure and added it to SilcClientEntry
3306 and SilcServerEntry as their first field in the structure. This
3307 way we can explicitly cast the ID entries to the SilcIDListData
3308 structure and get common data for the entries. In past, we had
3309 to first check what type of connection it is and then cast it to
3310 correct ID entry type. Now, we can directly cast the opaque
3311 pointer to the SilcIDListData (no matter what ID entry it actually
3312 is) and get the data needed.
3314 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3316 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3317 in some circumstances even if threre were timeout tasks, though not
3318 IO tasks, but tasks anyway. Now fixed.
3320 * Defined SilcServerConnection structure to hold connection specific
3321 stuff about directly connected servers and routers. The definition
3322 is currently in silcd/server_internal.h. I thought about having
3323 a bit more important role fro this struct but for now it is used
3324 only when connecting to other server (or router actually).
3326 * Added connecting retry support in server when connecting to
3327 router(s). The retry feature implement exponential backoff
3328 algorithm. Also, added SilcServerParams structure to hold default
3329 parameters for server. For now, it include these retry settings
3330 and are hard coded. After server is moded to be as Silc Server
3331 Library this structure will be more important.
3333 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3335 * Changed client librarys channel->clients table to SilcList and
3336 changed code accordingly.
3338 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Changed client's channel table to SilcList and changed code
3341 accordingly. Also changed SilcChannelClientEntry to include back-
3342 pointer to the channel so that client entry can use that structure
3343 as list as well and we have fast cross-reference to the channel.
3344 This change dramatically decreased the complexity of channel
3345 handling with client entry and vice versa (removed one extra
3346 loop when searching for channel entry from many functions).
3348 * Changed server->sim from table to SilcDList and changed code
3351 * NAMES command can now be used from user interface. It will show
3352 the user list on the channel, neatly.
3354 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3355 Code now saves realname of the user if it becomes available.
3357 * Renamed configure.in to configure.in.pre and made ./prepare
3358 script to automatically add correct version string to
3359 configure.in which it creates from configure.in.pre.
3361 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * NAMES command reply now shows users mode with the nickname when
3366 * Moved silc_client_ch[u]mode[_char] functions from
3367 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3368 place sucks, they are utility functions and should be in some
3371 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3373 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3376 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Added TRQ (efficient deque and list library) into lib/trq. This is
3381 a very good list library that is currently used in the SILC. Defined
3382 SilcList API over the library because I didn't like the API very
3383 much. See lib/trq/silclist.h for the API and examples of how to
3384 use the API. Fixed various places in the code to use the new
3385 SilcList API. The SilcList is meant for lists that has a structure
3386 already defined as a list. It is not suitable to add just some
3387 context to the list (in TRQ, the context is the list actually).
3389 So, I defined SilcDList that can be used for the purpose where
3390 predefined list structure does not exit. This can be used as
3391 such list. Now some context just can be added to the SilcDList.
3392 Currently this list is not used in the SILC just yet, though there
3393 are a lot places where this can replace dynamically allocated
3394 tables and I will fix these places, later, to use SilcDList.
3395 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3396 and use TRQ internally).
3398 Also fixed some annoying warning messages that the original TRQ
3399 code generated. Also minor changes to TRQ's Makefile.in.
3401 * Added support for querying by Client ID to both WHOIS and
3402 IDENTIFY commands into server, as required by the protocol.
3404 * Removed method function pointers from SilcBuffer structure. They
3405 weren't used to anything and just increased the context size for
3406 no good reason. This change also made silc_buffer_alloc and
3407 silc_buffer_free functions inline functions.
3409 * Disabled command flooding detection support until it's fixed so
3410 that it accepts commands in but does not execute them more than once
3413 * Added silc_net_localhost(), to return local hostname, into
3414 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3415 that must be initialized before calling silc_client_init.
3417 * Added new function: silc_server_send_notify_on_channels to send
3418 notify messages to all channels client has joined. It is assured
3419 that the message is sent only once per client.
3421 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3422 lib/silcutil/silcutil.[ch] as silc_format function. The new
3423 function is generic and is used by server as well, not only by
3424 the logging routines.
3426 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3427 the provided version string was not acceptable. Added new function:
3428 silc_ske_check_version into lib/silcske/silcske.h. The function
3429 must be implemented by the application (client or server) and it
3430 does not reside in the SKE library. The function checks the version
3431 string remote end sent.
3433 * Added back pointers (to opaque context and to SilcSocketConnection)
3434 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3436 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3437 duplicate packet context structure.
3439 * Changed `notify' client operation to send same arguments as client
3440 receives from server except for ID's. ID's are mapped to correct
3441 ID entry and that is returned. Also, if channel entry is not sent
3442 by server but the notify is for channel the channel entry is sent
3443 to application (otherwise application doesn't know that it is for
3444 channel (library gets it from packet's Destination ID)).
3446 * Added silc_client_remove_from_channels into client library to
3447 remove a client from all channels it has joined to. Used when
3448 received SIGNOFF notify from server. Added also new function
3449 silc_client_replace_from_channels to replace old ID entry with
3450 new ID entry on all channels. Used when received NICK_CHANGE
3453 * Fixed ID Cache list handling in silc_idlist_get_client in
3454 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3455 to get (or query) client by ID.
3457 * Updated TODO list.
3459 * Added connection authentication status message defined by the
3460 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3461 support for these into the code in client and server side.
3463 * Added generic function silc_client_send_command to send any command
3464 with variable argument list. Application should use this function
3465 to send commands if the command functions provided by the library
3466 does not suite for the application's user interface needs.
3468 * Added new `failure' client operation. Application is notified about
3469 received failure packet if client is executing a protocol. In this
3470 case the protocol's execution has failed.
3472 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3473 is required by the protocol.
3475 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3476 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3479 * Added status flag to SilcSKE object to indicate realtime status
3480 of the SKE protocol.
3482 * Application receives now exactly same command reply arguments as
3483 the library receives from server. However, if ID is received the
3484 corresponding ID entry is returned to the application (eg. Client
3485 ID is mapped to correct SilcClientEntry entry and that is returned).
3486 Changed command_reply client operation due to this change.
3488 * Changed all ID's in commands and in command replys as ID Payloads.
3489 Change affected both client and server side codes.
3491 All ID's sent in SILC network (with execption of ID's in SILC
3492 Packet header) are sent in ID Payload to support variable length
3495 * Server now notifies nick changes and notifies all clients on
3496 the channels about the new nickname (about the new Client ID,
3499 * Implemented CMODE command to change channel modes. Supports all
3500 channel modes defined by the protocol specs except ban and invite
3501 lists. (Also, private channel key mode is supported but support for
3502 setting private channel key in client is missing, thus, this mode
3503 has no effect on client side (except that server requires that the
3504 client uses private channel key and normal channel traffic does not
3507 Also, invite mode works per se, but INVITE command does not work
3508 yet correctly, so you can set channel as invite only channel but
3509 inviting clients to the channel does not work (it is yet to be
3510 thought what's the best way to do it).
3512 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3513 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3514 Implemented CUMODE command to change user's mode on the channel.
3515 Supports all modes defined by the protocol specs.
3517 * Added NAMES command reply to return users modes on the channel.
3519 * Removed unnecessary and slow ciphers from lib/silccrypt.
3521 * Set SO_KEEPALIVE option to connection sockets by default.
3523 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3525 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3526 redefined the Notify Payload into protocol specs.
3528 * Added silc_id_payload_parse_id to get ID directly from raw
3531 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3533 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3534 accept searching by Client ID as well.
3536 * Added support for LEAVE and SIGNOFF notify types in client library.
3538 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3539 to parse ID Payload from raw data.
3541 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Added flags parameter into silc_ske_assemble_security_properties
3544 function in lib/silcske/silcske.[ch].
3546 * Changed notify client operation to fit better for notify messages
3547 sent by server. The notify payload received from server is now
3548 passed to the application (after parsing it to SilcNotifyPayload).
3549 It is application's responsibility to retrieve the arguments
3550 from the payload and show the message the way it wants. The message
3551 sent by server is implementation specific.
3553 * Changed public keys to comply with the protocol specification.
3554 Old public keys are not supported anymore and are not compatible.
3556 * Removed nickname from Channel Payload as the latest draft removed
3557 it. The client must resolve the nickname from the NAMES command
3558 reply received when it joined the channel.
3560 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3562 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Fixed some errors in protocol specification drafts.
3566 * Created lib/silccore/silcnotify.c to implement Notify Payload
3567 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3568 generic payloads described by protocol specifications. The file
3569 includes implementations for ID Payload and Argument Payload.
3571 * Changed Command Payload implementation to use the new Argument
3572 Payload. Changed command_xxxx_payload to command_payload_xxxx
3573 to comply with SILC coding conventions.
3575 * Added suppport for Argument Payload handling in Notify Payload
3576 implementation as protocol requires it. Added the new support
3577 into server and client lib as well.
3579 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3581 * Added support for multiple nicknames on same channel. [n] is
3582 added locally to the nickname if there are more than one same
3583 nicknames on the channel.
3585 * Server now sends all nicknames that matched WHOIS request.
3586 Client also shows the list received from server.
3588 * Added TOPIC command to client side. User can now set and show
3589 current topic on channel.
3591 * Added MOTD command to client and server. Also, server sends the
3592 motd when client connects to the server.
3594 * Changed version strings to comply ISO 8601.
3596 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Fixed protocol error handling in client library. It should now
3599 cope even if the SKE fails for some reason.
3601 * Made new protocol specification drafts for submitting to IETF.
3603 * Implemented TOPIC command to server in silcd/command.c.
3605 * Added two new notify types into lib/silccore/silcnotify.h:
3606 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3607 notify nickname change and topic setting/change on a channel.
3609 * API change of command_reply operation in client library. The
3610 application gets now the status type received from server as well.
3612 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3616 * Cras fixed and optimized the packet handling even further and
3617 it should work now. Minor change to the prototype of function
3618 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3620 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Added new function into lib/silcutil/silcschedule.[ch]:
3623 silc_schedule_with_fd to select() a specified fd. The function
3624 returns after timeout expires or data arrives or goes. The
3625 function is used by packet routines to wait that all data is
3626 received from network.
3628 * Fixed data reading from network in lib/silccore/silcpacket.c.
3629 The code now assures that all data is read from the fd and then
3630 continues packet processing. This was a bug fix since the code
3631 used to drop some data in some circumstances.
3633 * Added new function into lib/silcclient/client.[ch]:
3634 silc_client_start_key_exchange to start key exchange after
3635 connection has been established to server. The code internally
3636 now uses this funtion but its main purpose was to provide it
3637 for applications that perform their own connecting. After
3638 application has created a connection it merely calls this
3639 function to start the key exchange between client and server.
3640 The library takes care of everything else after that.
3642 Updated also lib/silcclient/README to explain the usage of
3645 * Do not send to application information that connection has
3646 been established. Application gets notified it by connect
3649 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3651 * Applied cras's patch to add silc_schedule_one function. The
3652 function runs scheduler once and returns.
3654 * Fixed the scheduler after cras messed it up. The timeout
3655 handling works now as it's supposed to work.
3657 * Added into lib/silccore/ silcnotify.h to include notify
3658 message types support. Changed silc_server_send_notify*
3659 functions, in server.[ch], to support those new notify types.
3660 Added the support for the notify types into client library,
3661 as well. Added new notify client operation into ops.h in
3664 * Changed silc_server_packet_send_to_channel to send normal
3665 packets instead of just channel message packets. The function
3666 is now used to send the notify packets to channels. It is not
3667 used to send channel message packets anymore, as server never
3670 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3671 va_arg()s as it seems to require it nowadays. I guess, if SILC
3672 is compiled with older va_arg() the new code should work anyway.
3674 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Splitted core library. Core library (lib/silccore) includes
3677 now only SILC protocol specific core (and common) components.
3678 Created new utility library (lib/silcutil) that includes more
3679 generic purpose stuff. The stuff for util library was taken
3680 from the old core library. This was minor and easy split.
3682 * Created SILC Client Library (lib/silcclient) that includes
3683 implementation of the SILC client without user interface. This
3684 was major move from silc/ directory. The code has been changed
3685 so that it is transparent towards the user interface. The
3686 silc/ directory includes now the same user interface as before
3687 and it uses the new client library. Read lib/silcclient/README.
3688 Basicly, the client library performs everything else related
3689 to SILC except user interface handling. Also, configuration
3690 files are considered to be part of user interface and library
3691 does not handle them.
3693 This change also changed a lot of structures, function naming etc.
3694 Most important change was that SilcClientWindow object was
3695 renamed to SilcClientConnection in the client library. Created
3696 also new file lib/silcclient/ops.h. Also added new files
3697 silc/local_command.[ch] and silc/client_ops.[ch].
3699 All these changes were made to make it easier for user interface
3700 designers to create what ever user interface for the SILC client
3703 It is also expected that the server will be moved to lib
3704 directory as well and SILC Server Library will be created;
3705 sometimes in the future.
3707 * Removed Local commands from lib/silccore/silccommand.h as
3708 they are application specific and new client library does not
3709 handle any of those anymore.
3711 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3712 old client implementation in silc/.
3714 * Added support for callback functions in SILC_LOG_* macros.
3715 Application can now set its own callbacks that will be called
3716 instead of using the default functions that will always print
3717 the debug messages to stderr (or stdout). Also, debugging can
3718 now be disabled by setting silc_debug to FALSE and re-enabled by
3719 setting it to TRUE. Note, that logging will still work even
3720 if debugging is disabled.
3722 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3723 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3724 silc_log_reset_debug_callbacks.
3726 * To enable debugging in silc client one must give now -d
3727 option on command line.
3729 * Changed silc_schedule_init to automatically allocate task queues
3730 if they are not allocated before calling it.
3732 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Added GMP 3.1 into math library.
3736 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3739 a channel in SILC network. The packet is used by servers and
3740 routers to notify other routers that user has left a channel.
3741 This little feature was missing until now. Added the feature
3742 to protocol specification as well.
3744 Added functions: silc_server_send_remove_channel_user and
3745 silc_server_remove_channel_user into server.[ch].
3747 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3748 lib/silccore/silcpacket.h. However, they are not implemented
3751 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Fixed joining to a channel and sending channel messages
3754 between server and router. The channel message sending should
3755 now work inside a cell.
3757 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3759 * Fixed the private message sending between server and router.
3760 The private message sending should now work inside a cell.
3762 * Added silc_server_replace_id into server.[ch] to replace
3763 existing ID in the SILC network.
3765 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3766 and silc_idlist_replace_server_id into idlist.[ch] in server.
3768 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Fixed the server to server connections. Server can again now
3771 connect to router. Router to router connections probably does
3774 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Added dynamic protocol registering support. Now protocols can
3777 registered and unregistered on the fly. Patch by cras.
3779 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3781 * Added lib/contrib directory to hold routines that some platforms
3782 don't have but are needed by SILC.
3784 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3785 into lin/contrib to provide getopt() and getopt_long() for
3786 those who don't have it.
3788 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Added AWAY command to client. When away message is set and
3791 client receives a private message packet the client automatically
3792 replies to the sender with the away message.
3794 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3795 bug seemed to be the cause of recent problems when compiling
3798 * Added version detection support to SKE protocol specification
3799 and added the new changes to the SKE implementation as well.
3800 There were other minor changes in the SKE protocol as well.
3802 Many changes in lib/silcske/silcske.[ch] and in
3803 lib/silcske/payload.[ch].
3805 * Added ^U functionality, clear input line. Patch from cras.
3807 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Mainly small bugfixes on core library. Fixed some debugging
3810 logging and buffer overflow in silclog.c.
3812 * Updated config.sub and config.guess on the distribution tree.
3814 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3816 * Added command lagging support in server. Client may execute
3817 commands now only once in two seconds.
3819 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Optimized packet reception. MAC computation and checking is now
3822 also more optimized. A lot previously duplicated code is now
3823 used as generic by both client and server.
3825 * Fixed key pair generation in clientutil.c
3827 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Added into lib/silccore/silcbufutil.[ch] new function;
3830 silc_buffer_realloc.
3832 * Moved generic packet sending/encryption functions to
3833 lib/silccore/silcpacket.[ch] from client and server. Some
3834 rewriting of the functions.
3836 * Moved all generic packet reception/decryption functions to
3837 lib/silccore/silcpacket.[ch] from client and server. The
3838 packet processing is now much cleaner in both client and server.
3839 These were major changes in both client and server.
3841 * Created many common functions in server to do packet sending.
3842 Previously code were duplicated a lot, this has been removed
3845 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Rewrote major parts of the ID cache system. Don't know
3848 whether it is better now or not but at least the API is more
3851 * Major rewrite on ID cache stuff on client because of the ID
3852 cache API changes. Added idlist.c to client.
3854 * Also major rewrite on ID cache stuff on server as well.
3855 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3856 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3857 in hand, instead they are all put into the ID cache system now.
3858 All server_idlist_* routines uses ID cache now instead of
3859 traversing its own lists (those lists does not exist anymore).
3860 SilcIDList though still exists. Also, SilcXXXEntry's are
3863 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * Finally made the SKE implementation compliant to the protocol
3866 specification. All mp integers are now binary encoded as
3867 opposed being HEX encoded.
3869 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3872 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3873 functions: silc_[encode/decode]_pem. Also added function
3874 silc_encode_pem_file to PEM encode with newlines ('\n') for
3877 * SILC public keys are now encoded either PEM or binary. Same
3878 option is for private keys as well. By default private keys
3879 are binary encoded and public keys PEM encoded. Silly HEX
3880 encoding were removed.
3882 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3883 function to create fingerprints.
3885 * Fixed a bug in SHA1; does not change the original data anymore.
3887 * Partly implemented INFO command on client and server side.
3888 Fixed CLEAR command. Changes to SERVER command; show current
3889 server(s) when giving command without arguments. Added
3890 VERSION command to client.
3892 * Added check to server that unregistered connections cannot
3893 execute commands (unless it is specificly allowed).
3895 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3897 * Fixed screen refresh.
3899 * Fixed channel joining bug from client. On some circumstances
3900 client tried to join to a channel it had already joined.
3902 * Added public key verification process into client's protocol.c.
3903 The client now verifies the public key from user and saves
3904 it into ~./silc/serverkeys/ directory.
3906 Added into: clientutil.[ch]: silc_client_verify_server_key.
3908 * Changed SKE protocol's silc_ske_initiator_finish function
3909 to accept callback function that verifies the received public
3910 key. Removed old silc_ske_verify_public_key function.
3912 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3915 silc_pkcs_private_key[_data]_set.
3917 * Made the password and public authentication more cleaner in
3918 server's protocol.c.
3920 * Removed historic and obsolete protocol `channel_auth' from
3921 both client and server.
3923 * Removed wrong way of sending command status messages from
3924 server to client in server's command.c. The old way violated
3925 protocol specification.
3927 Changes to silccore/silccommand.[ch]: removed
3928 silc_command_encode_status_payload -> not needed anymore,
3929 changed silc_command_encode_payload_va to accept extra
3930 argument on variable argument list. The argument type must
3931 now be provided to the function. Also, added new function:
3932 silc_command_encode_reply_payload_va which is same as
3933 normal command_encode_payload_va except command status type
3934 is provided as extra argument.
3936 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Added ~./silc directory handling. The directory includes the
3939 public and private keys for the client.
3941 Added silc_client_check_silc_dir, silc_client_create_identifier
3942 and silc_client_load_keys.
3944 * Implemented SILC protocol compliant public key. Added public
3945 and private key saving to and loading from files.
3947 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3948 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3949 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3950 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3951 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3953 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3954 silc_pkcs_load_[public/private]_key.
3956 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * Added silc_server_get_route (route.[ch]) to get connection
3959 data for the fastest route for given ID.
3961 * Implemented INVITE command on client and server. The command
3962 were re-defined in the SILC Protocol Specification and the
3963 implementation now complies with the specification.
3965 * Implemented PING command on client and server.
3967 * Implemented NAMES command on client and server. The server side
3968 supports currently only normal server not router server yet.
3969 Some changes to NAMES definition in SILC protocol specification.
3971 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Implemented LEAVE command on client and server.
3975 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3976 again. This change was made to the protocol as well. Server
3977 should not violate the protocol specification anymore.
3979 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3982 was tested. SOCKS4 was not but should work anyway.
