3 * Fixed a bug in Irssi SILC client; do not show that you are
4 server/router operator if you really are not. Affected file is
5 irssi/src/silc/core/client_ops.c.
7 * Renamed silc_command_free_payload to silc_command_payload_free.
8 Affected file lib/silccore/silccommand.h
10 * Added silcmath.h to include the prototoypes of various routines
11 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
14 * Changed the following headers to ROBODoc format:
16 lib/silccore/silcchannel.h
17 lib/silccore/silccommand.h
19 lib/silccore/silcidcache.h
20 lib/silccore/silcmode.h
21 lib/silccore/silcnotify.h
22 lib/silccore/silcpacket.h
23 lib/silcmath/silcmath.h
25 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
27 * Added checking to the server code not to start the server if
28 ciphers and stuff are not configured properly. Affected files
29 silcd/serverconfig.[h] and silcd/server.c.
31 * Changed the layout of the header files of the public interfaces
32 in the SILC libraries. The new layout supports ROBODoc
33 documentation tool (and some others) so that it is easy to create
34 a library reference manual. All the other headers and source
35 code must still follow the CodingStyle document. Also source
36 code must not include these ROBODoc stuffs, only the headers.
37 Furthermore, all public interface headers must now be named
38 by using `silc' prefix, example: silcapi.h, silccipher.h.
39 Some files were renamed due to this. All the other headers
40 must not be used as public interfaces. I will update the
41 CodingStyle document later. Changed following headers, so far:
43 lib/silcclient/silcapi.h
44 lib/silccore/silcauth.h
45 lib/silccore/silcprivate.h
46 lib/silccrypt/silcdh.h
48 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
52 * Removed silc_client_packet_send_flush from the client library
53 as it is not needed. Affected file lib/silcclient/client.[ch].
55 * Added printing of message of unresolved authentication method
56 to the Irssi SILC client. Added it to the module formats.
57 Removed the same message from the client library.
59 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
61 * Added new distribution feature, DISTLABEL. Every distribution
62 can define own preprocessor label that can be used in the
63 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
64 file distributions, acconfig.h.pre and prepare.
66 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
68 * Added Makefile.defines_int to include the actual definitions
69 for Makefile.defines.in. Tested the new distribution system,
70 created distributions and tested installation.
72 * Added AWAY message printing to the Irssi SILC client. Added
73 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
75 * Added SCONNECT command to call the SILC's CONNECT command.
76 Cannot use CONNECT directly since Irssi uses that internally.
77 Affected file irssi/src/silc/core/silc-servers.c.
79 Added ACTION local command. It is same as ME command but takes
80 the channel as mandatory argument.
82 Rewrote some of the Irssi's help files to suite for SILC
85 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
87 * Added Makefile.defines[.in] that should for now on be included
88 in all Makefile.am file in the source tree. That file includes
89 all common compilation definitions for SILC source tree.
91 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
93 * Minor changes to the ./prepare script to change the package
94 name according the distribution name to the configure.in.
96 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * Created new distribution system. Added file `distributions'
99 that defines all the distributions that can be created out of
100 the SILC source tree. The ./prepare script now reads that
101 file to determine how to prepare the distributions. The
102 first argument to the ./prepare is the name of the distribution
103 and second is the version of the distribution. If given
104 without arguments it creates the default (toolkit) distribution
105 with the default version (defined in ./prepare).
107 All Makefile.am files that are subject to the distributions
108 are now named as Makefile.am.pre. These are ./Makefile.am
109 and lib/Makefile.am. Others may be changed later.
111 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
113 * Added invite list, ban list, some key management and connection
114 error message printing to module formats in the Irssi SILC client.
116 * Added new silc_client_set_away_message to set the away message
117 that is back to the person who sent private message. The
118 affected file lib/silcclient/silcapi.h and the
119 lib/silcclient/client_prvmsg.c.
121 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
123 * Fixed the private message sending in the Irssi SILC client,
124 added local command KEY to the Irssi SILC client.
126 Added key management and key agreement message formats to the
127 irssi/src/fe-common/silc/module-formats.[ch].
129 Added USERS (alias WHO) printing, server/router operator
130 indication and LIST command printing to the module formats.
132 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
134 * Fixed channel joining notify handling, cumode notify handling
135 from Irssi SILC client.
137 * Added SILC specific module-formats to the Irssi SILC client so
138 that SILC specific message hilighting, colors etc is possible.
139 Affected file irssi/src/fe-common/silc/module-formats.[ch].
141 Added channel mode, channel user mode, actions, notices,
142 whois and whowas printing to the the module-formats.c.
144 * Fixed a bug in channel deletion in the server. The channel
145 is not left to the cache even if the channel founder auth mode
146 is set when there are no users anymore on the channel. Affected
149 * The silc_net_localhost now resolves the entire hostname including
150 the domain name. Affected file lib/silcutil/silcnet.c.
152 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
154 * Changed the ask_passphrase client operation to be ascynchronous.
155 It has now a completion callback and a context that the
156 application must call after it has got the passphrase from
157 the user. Affected files lib/silcclient/silcapi.h,
158 lib/silcclient/protocol.c, lib/silcclient/command.c and
161 Added SilcAskPassphrase callback that the application calls
162 to deliver the passphrase to the library.
164 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
165 The public key verification and especially a certificate
166 verification is asynchronous procedure.
168 Added new SILC_SKE_STATUS_PENDING status to indicate the
169 request is pending and a callback will be called to finalize
172 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
173 indicate that remote end did not send its public key (or
174 certificate), even though we require it. Added check for this
175 condition in the SKE. This was a security bug, now fixed.
177 Defined new SilcSKEVerifyCbCompletion callback that is called
178 when the verification process is completed.
180 The affected files lib/silcske/silcske_status.h and
181 lib/silcske/silcske.[ch].
183 * Changed the verify_public_key client operation to be async
184 as well. Defined SilcVerifyPublicKey callback that is used to
185 indicate the success of the public key verification process.
187 Changed the server and client to use the new async client
190 * Changed the Irssi SILC client's internal scheduler to be called
191 twice as many times as it used to be. As a result the client
192 should be a bit faster now. Affected file is
193 irssi/src/silc/core/silc-core.c.
195 * Added support to Irssi SILC client of asynchronous public key
196 verification and passphrase inquiry. Affected file is
197 irssi/src/silc/core/silc-core.c.
199 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
201 * Do not say "You have left channel %s" in client library.
202 Moved it to the application. Affected files are
203 lib/silcclient/command.c and silc/client_ops.c.
205 * Fixed silc_client_get_clients. Command context was not
206 duplicated and was freed memory in the callback. Affected
207 file lib/silcclient/idlist.c.
209 * Do not say "you are now talking..." on JOIN command in the
210 client library. The appliation must handle it.
212 * Do not say ".. changed topic to" in command reply in the
213 client libary. The application must handle it.
215 * Fixed TOPIC command sending in the client library.
217 * Fixed a memory leak in silc_client_command_free in the file
218 lib/silcclient/command.c.
220 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
222 * Imported a modified version of Irssi client to the source tree.
223 The Irssi will be used to create a new client called
224 Irssi SILC. Imported to irssi/.
226 Added silc_core_init_finish function to the Irssi. Affected
227 file irssi/configure.in.
229 A lot changes in the Makefile.ams around the irssi tree.
231 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
233 * Do not rehash if the new size is same as the old size of the
234 hash table, in the silc_hash_table_rehash*. The affected file
235 lib/silcutil/silchashtable.c.
237 * Replaced hash_table_del_by_context calls from the server
238 (when channel->user_list and client->channels) to the
239 hash_table_del as it is sufficient and faster.
241 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
243 * Added silc_hash_table_list, silc_hash_table_get and the
244 SilcHashTableList structure to provide an alternative way to
245 traverse the hash table. The affected files are
246 lib/silcutil/silchashtable.[ch].
248 * Changed the server's idlist routines to use the hash table
249 routines to optimize the code.
251 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
253 * Replaced the client entry's `channel' list and channel entry's
254 `user_list' list to hash tables for optimized lookup. Changed
255 the code to use the hash table interface around the code.
256 Affected file lib/silcd/idlist.[ch].
258 * Added `auto_rehash' boolean argument to the function
259 silc_hash_table_alloc to indicate whether the hash table should
260 auto-rehash when it thinks is appropriate time. It will
261 increase the hash table size if the there is twice as much
262 entries in the table than the size of the table, and will
263 decrease the size if there are twice as less entries than
264 the size of the table.
266 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
268 * Fixed silc_xxx_get_supported to not crash at some circumstances.
270 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
272 * silc_idcache_purge_by_context deletes the entry now by context
273 as it is supposed to do. Affected file lib/silccore/idcache.c.
275 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
276 client is not anymore valid (WHOWAS givens the info) and not
277 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
279 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
281 * Removed the `data' and `data_len' arguments from the ID Cache
282 interfaces and added `name' argument. ID Cache does not handle
283 anymore the binary data only a names associated with given ID.
285 * When hashing a Client ID with silc_hash_id the entire ID is
286 not hashed anymore, instead only the hash of the Client ID is
287 hashed. This way we can access the Client ID from the cache
288 with Client ID but with the hash of the ID (which is a hash of
289 the nickname) as well without any difference in performance.
291 Added also silc_idcache_find_by_id_one_ext to do one on one
292 searching when we have the actual ID. Added also function
293 silc_hash_client_id_compare. The affected files are
294 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
296 * When hashing the name associated with a ID it is always done
297 in lowercase. This way we can access the cache without worrying
298 about case-sensitivity, even though, for example nicknames are
301 * Fixed a bug in server with channel message sending. It put
302 wrong ID type as destination ID. The affected file
305 * silc_idcache_del_by_context now deletes from all hash tables
306 by context. Affected file lib/silccore/idcache.c.
308 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
310 * Changed the client library to use the new ID Cache interface.
311 Changes around the source tree.
313 * Added silc_hash_table_rehash_ext to rehash with specific
314 hash function. Affected file lib/silcutil/silchashtable.[ch].
316 * Added silc_hash_string_compare to compare two strings in the
317 hash table. Affected file lib/silcutil/silcutil.[ch].
319 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
321 * Added new function silc_idcache_del_by_context into the
322 lib/silccore/idcache.[ch].
324 * Changed the server's ID list routines to use the new ID Cache
325 interface. Changes around the source tree.
327 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
329 * Added silc_hash_table_del[_by_context]_ext functions in to the
330 lib/silcutil/silchashtable.[ch].
332 Removed silc_hash_table_find_all* routines and added new
333 silc_hash_table_find_foreach to replace them.
335 Added silc_hash_table_replace_ext function as extended
336 replacing function. Separated the simple hash table interface
337 from the extended hash table interface in the file
338 lib/silcutil/silchashtable.h.
340 * Fixed minor bugs and changed it to use some of the new
341 hash table functions in lib/silccore/idcache.c
343 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
345 * Added new function silc_hash_table_find_all to return all keys
346 in the hash table by the specified key. As the hash table is
347 collision resistant it also makes it possible to have several
348 duplicate keys in the hash table. This function may be used to
349 find all of the keys from the hash.
351 Added user_context arguments to the SilcHashFunction,
352 SilcHashCompare and SilcHashDestructor to deliver user specified
355 Added new fuctions silc_hash_table_find[_all]_ext to do
356 extended lookup with specified hash and compare functions and
357 specified user contexts.
359 Added new function silc_hash_table_add_ext to add the key
360 with specified hash function and user context.
362 Added new function silc_hash_table_foreach to traverse all
363 entrys in the hash table. Added SilcHashForeach callback
366 Added new function silc_hash_table_del_by_context to delete
367 the entry only if the context associated with the key matches.
369 Affected files are lib/silcutil/silchashtable.[ch].
371 * Removed silc_hash_[server/client/channel]_id and added just
372 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
373 silc_hash_id_compare to compare two ID's using as the hash table
374 comparison function. Added also silc_hash_data to hash
375 binary data and silc_hash_data_compare to compare it.
377 * Removed silc_idlist_find_client_by_hash as it is not needed
378 anymore. Affected file silcd/idlist.[ch].
380 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
381 to use internally the SilcHashTable. The new ID Cache is a lot
382 faster than the old one. Some of the ID Cache interface was also
383 rewritten and obsolete and stupid functions were removed.
385 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
387 * Added entry_count field to the SilcHashTable to keep the number
388 of the entries in the table. Implemented the function
389 silc_hash_table_rehash. Added new function
390 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
392 Fixed a minor bug in silc_hash_table_free.
394 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
395 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
396 into the lib/silcutil/silcutil.[ch].
398 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
400 * Implemented a collision resistant hash table into the
401 lib/silcutil/silchashtable[ch]. See the header and the source
402 for the SilcHashTable API.
404 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Merged dotconf version 1.0.2 into lib/dotconf.
408 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
410 * Do not compile anything in lib/silcsim/* if the SIM support
411 is not enabled. The tree should now compile without problems
414 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
416 * Compiled the SILC under cygwin. Compiled and tested briefly
417 without problems. More tests needed. The SIMs didn't compile
420 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
422 * Fixed possible crash in silc_get_username in the
423 lib/silcutil/silcutil.c.
425 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
427 * Fixed a va_arg in silc/client_ops.c.
429 * Oops, RC5 routines were named AES and caused some problems
430 when not using SIM's. Affected file lib/silccrypt/rc5.c.
432 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
434 * Added new SilcIDIP structure into the lib/silccore/id.h and
435 replaced the old `ip' fields from all SILC ID's to that type.
436 This is a step towards IPv6 support.
438 The silc_id_get_len takes now the ID as an extra argument.
439 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
440 both IPv4 and IPv6 based ID's.
442 The affected files are lib/silccore/id.[ch] and other files
443 around the tree using these routines.
445 * Removed the ID length arguments in server from various
446 silc_server_send_notify_* routines -> they are not needed
449 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
451 * Fixed memory leak in silc_encode_pem_file in the file
452 lib/silcutil/silcutil.c.
454 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * Check minor version as well in the SKE. Affected files are
457 silcd/protocol.c and lib/silcclient/protocol.c.
459 * Added --identifier option to the server so that an identifier
460 can be when creating the public key for the server. Affected
461 file is silcd/silcd.c.
463 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
464 lib/silccrypt/silcpkcs.c.
466 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
468 * Register default ciphers and stuff when using -C option with
469 the server. Affected file sildc/silcd.c.
471 * Put back the servers public key filename format, it is better
472 than the new one. For now, the client keys are saved with the
473 new filename format. The affected file silc/client_ops.c.
475 * Implemented the Cipher API for the rest of the ciphers that
476 did not implement it or implemented it the wrong way.
478 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
480 * Register default ciphers and stuff when using the -S option
481 in the client. Affected file silc/silc.c. Same also when
482 creating new key pair with -C option.
484 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
486 * Fixed the silc_verify_public_key client operation function to
487 save the public keys differently. The fingerprint is now
488 used as filename and not the hostname. This way also the
489 client keys are saved uniquely and not with hostnames. The
490 affected file is silc/client_ops.c.
492 * Trimmed the silc_hash_fingerprint function to remove extra
493 whitespaces from the end of the fingerprint. The affected
494 file is lib/silccrypt/silchash.c.
498 * Added silc_cipher_register_default function to register all
499 default ciphers. It can be used when configuration files
500 does not exist and the application does not want any specific
501 ciphers in any specific order.
503 The SilcDList is now used as silc_cipher_list dynamically
504 allocated cipher list. Removed the static list all together
505 and now all ciphers must be allocated to the dynamic list.
506 The silc_cipher_alloc routine was changed to check only the
509 All silc_cipher_* routines that used to return int returns
512 The affected files lib/silccrypt/silccrypt.[ch].
514 * The same thing was done to silc_hash_* as for silc_cipher_*
515 routines. Affected files lib/silccrypt/silchash.[ch].
517 * The same thing was done to silc_pkcs_* as for silc_cipher_*
518 routines. Affected files lib/silccrypt/silcpkcs.[ch].
519 Added also silc_pkcs_[un]register[_default] functions.
520 Removed the data_context from the PKCS API.
522 * Added silc_hmac_register_default function to register default
523 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
524 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
525 to unregister all hmacs at once.
527 * Register the default ciphers, hash functions, PKCSs and HMACs
528 if client's configuration file does not exist. The affected
531 * The client did not load the hash functions from the SIM
532 modules at all. Added support for this. Affected file is
535 * When decoding public key with silc_pkcs_public_key_decode, check
536 the supported algorithm only if PKCS are registered. Affected
537 file lib/silccrypt/silcpkcs.c. The same was done with the
538 silc_pkcs_private_key_decode.
540 * Fixed the SILC List routines to keep the list always in order.
541 It used to change the list's order when traversing the list but
542 not it preserves the order. Affected file lib/trq/silclist.h.
544 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
546 * Added the client library to use the SilcSocketConnection's
547 reference counter (by silc_socket_dup) to prevent the bug that
548 the socket object may be freed underneath async operation.
550 * The name resolv library checking fixes in the configure.in.pre.
553 * Created new version of the protocol drafts for future
554 development. The -03 drafts are the ones that will be changed
555 in the trunk now and the -02 will remain as they are.
557 * Send list of CUMODE notifys to the router when announcing
558 the channel users to the router. Affected file silcd/server.c.
559 If the router receiving channel founder CUMODE for a channel
560 that already has channel founder it will send CUMODE notify
561 to the sender to remove the channel founder rights from the
562 announced client. Affected file silcd/packet_receive.c.
564 * The CUMODE notify may now use Server ID as well as the entity
565 who changes the mode. Updated protocool specs.
567 * Updated INSTALL and README files.
569 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * New web pages in the http://silc.pspt.fi. The pages was
576 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
578 * Implemented the [DenyConnectin] config section in the server.
579 Added silc_server_config_denied_conn to check whether incoming
580 connection is denied. Affected file silcd/serverconfig.[ch].
582 * Do not check the ports when checking the incoming configuration
583 data if the port is 0, meaning any. Affected file is
584 silcd/serverconfig.c.
586 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
588 * Fixed buffer overflow in silc_string_compare in the file
589 lib/silcutil/silcutil.c.
591 * Fixed double free in silc_server_command_leave in the file
594 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
596 * Fixed the version checking in the server. Affected file is
599 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Fixed the configuration data fetching when accepting new
602 connections in the server. Affected file silcd/server.c.
604 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
606 * Added `sender_entry' argument to the function
607 silc_server_packet_relay_to_channel so that we can check
608 whether some destination actually belongs to the same route
609 the sender belongs (ie, we must not resend the packet to the
610 sender). Affected file silcd/packet_send.[ch].
612 * Added `servername' field to the SilcClientEntry in the server
613 to hold the name of the server where client is from. Affected
614 file is silcd/idlist.h.
616 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * Moved the channel message encrypting in the router betwen
619 router connections from silc_server_channel_message to the
620 silc_server_packet_relay_to_channel since we want to check
621 whether we have anybody channel before encrypting anything.
622 Affected files silcd/packet_[receive/send].c.
624 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
626 * Fixed the [AdminConnection] server config section to support
627 multiple entries. Affected file silcd/serverconfig.c.
629 * Added support into the server to check the validity of the
630 incoming connection before executing any KE or authentication
633 * The connection configuration is now saved to the KE and
634 connection auth protocol contexts and not fetched anymore in
635 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
637 * The local hosts listenning address and port is also resolved
638 now when starting the server. We want to have the socket object
639 to include the real address and port for the listener. Added
640 new function silc_net_check_local_by_sock into the files
641 lib/silcutil/silcnet.[ch].
643 * Fixed a broadcast bug in server -> do not broadcast if we
646 * Fixed a routing bug. Do not route broadcast packets ever.
647 Broadcast packets must be processed always and not routed since
648 they may be destined to some other host than yourself and thus
649 would get routed without no good reason. Affected file is
652 * Added function silc_server_config_is_primary_route to check
653 whether primary router connection has been configured (a router
654 configuration that we are initiating). If there is not, we
655 will assume that there is only two routers in the SILC network
656 and we will use the incoming router connection as our primary
657 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
659 * Changed the order of the broadcasting. Broadcast _after_ the
660 packet has been processed not before. Affected file is
663 * Fixed a [ClientConnection] parsing bug. The port was never
664 parsed correctly thus resulting to port 0. Affected file
665 silcd/serverconfig.c.
667 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
668 argument and did not set the broadcast packet flag. Affected
669 file silcd/packet_send.c. Fixed same bug in the function
670 silc_server_send_notify as well.
672 * If we receive NEW_ID packet for our own ID in the server, ignore
675 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Removed the nickname from the Private Message Payload.
680 Updated the code and the protocol specs.
682 * Updated protocol specs for submitting to the IETF.
684 * Tweaked the Random Number Generator a bit. Affected file
685 lib/silccrypt/silcrng.c. Exported a new function
686 silc_rng_[global]_add_noise which can be used to add more
689 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
691 * Do not parse packets with different timeout when protocol
692 is active -> may cause problem with rekey. Affected file
695 * When server receives signoff notify it must not create
696 new channel key if the client is on any channels since the
697 sender of the signoff notify will create it.
699 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * Added printing of error messages during SKE protocol from the
702 failure packet sent by server during SKE. Affected file
705 * Removed the client's failure_callback handling with timeout
706 and handle it immediately when received.
708 * The SKE library returned wrong type in SUCCESS and FAILURE
709 packets. They must be 32 bit MSB not 16 bit MSB.
711 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
713 * Ok, rewrote the logic of the re-key and now it seems to work.
714 I tested it on high traffic with frequent re-keys without
715 problems. Added hmac_receive (and renamed hmac to hmac_send)
716 in SilcClientConnection in lib/silcclient/client.h and
717 in SilcIDListData in silcd/idlist.h. Also, removed the
718 SilcPacketParserContext's cipher and hmac fields as they are
719 not needed anymore and actually caused some problems when
720 the ciphers and hmac's changed underneath the packet parser.
722 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * If re-key protocol is active then process the incoming packets
725 synchronously since we must assure that icoming packets encrypted
726 with the old key is processed before the new keys is set to
727 use. This is true other packets than for REKEY packets.
728 Affected file silcd/server.c. The same was done to client library
729 as well, affected file lib/silcclient/client.c.
731 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
733 * Fixed bug in client and server to accept the force send if
734 the packet is send from silc_[server/client]_packet_process
735 function. Otherwise the packets are never delivered, oops.
737 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
739 * Disable force sending of packets when REKEY protocol is active.
740 We must assure that no packet is sent directly when rekey is
741 performed. All packets must be sent through packet queue.
742 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
743 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
744 function is silc_[server/client]_packet_send_real to check
747 * Replaced the SIM paths from example config files to
748 /usr/local/modules. Also, make install creates now
749 /usr/local/silc/logs directory to hold all the SILC server
752 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
754 * Made the configure.in.pre work on Solaris. Patch by salo.
756 * Made all ciphers compatible with non-x86 machines. Defined
757 CBC mode macros into lib/silccrypt/ciphers_def.h.
759 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Fixed the make install.
763 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
765 * When MAC computation fails the silc_packet_decrypt returned 0
766 even though it was supposed to return -1. Fixed this. The
767 affected file is lib/silccore/silcpacket.c.
769 * Do not replace the config files in /etc/silc (in make install)
770 if they already exist. Affected file ./Makefile.am.
772 * Do not send re-key packets immediately but through packet queue.
773 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
775 * Changed silc_net_check_host_by_sock to return FALSE if the
776 IP/DNS could not be resolved. Though, it returns the IP address
777 now even if it could not resolve it (but returns also FALSE).
778 Affected file lib/silcutil/silcnet.[ch].
780 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
782 * Added silc_pkcs_decode_identifier to decode the public key's
783 identifier. Affected file lib/silccrypt/silpkcs.[ch].
784 Added also silc_pkcs_free_identifier. Added also new context
785 SilcPublicKeyIdentifier.
787 * Added -S option to the silc client. It is used to dump the
788 contents of the specified public key file.
790 * Changed the PKCS api to return the public key length when
791 setting the public key.
793 * Fixed a fatal bug in the public and private key file loading.
794 Affected file lib/silccrypt/silcpkcs.c.
796 * Execute the packet parsing for client with zero (0) timeout
797 if the protocol is active. Affected file silcd/server.c.
799 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * Made the key generation options to the silcd program. Added
802 -C option, equivalent to client's option.
804 * Added new [ServerKeys] config section to the server. It
805 configures the server's public and private key.
807 * Defined generic Public Key Payload into the protocol
808 specification to send specific type of public keys and
811 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
812 public key or certificate.
814 * Implemented the GETKEY command to the server and to the
815 client library and on user interface.
817 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
819 * Made preliminary `make install' work.
821 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
823 * Added SilcServerRekey context into silcd/idlist.h.
825 * Added the PFS support as defined in the specification to the
826 SKE protocol. Affected files lib/silcske/*.c.
828 * Added `ske_group' field to the SilcServerRekey context to hold
829 the number of the SKE group that is used with PFS in re-key.
830 Affected file silcd/idlist.h.
832 * Added PFS re-key support to the server. Affected file is
835 * Added silc_protocol_cancel to cancel execution of the next
836 state of the protocol. Affected file is
837 lib/silccore/silcprotocol.[ch].
839 * Added the re-key support with and without PFS to the client
840 library. Re-key is performed once in an hour, by default.
842 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
843 Added silc_client_rekey_callback and silc_client_rekey_final.
844 Affected files are lib/silcclient/protocol.[ch] and
845 lib/silcclient/client.[ch].
847 * Removed the `hmac_key' and `hmac_key_len' fields from the
848 SilcClientConnection structure; not needed. Affected file is
849 lib/silcclient/client.h.
853 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
855 * Do not ask whether user wants to use the negotiated private key
856 for private messages, just use it. Affected file is
857 silc/local_command.c.
859 * Added `send_enc_key' and `enc_key_len' fields to the
860 SilcIDListData structure since they are needed in the re-key
861 phase. Affected file is silcd/idlist.[ch].
863 * Implemented the simple re-key protocol into the server.
864 Affected files silcd/server.c and silcd/protocol.[ch]. The
865 re-key will be performed once in an hour, by default.
867 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
868 Added silc_server_rekey, silc_server_rekey_callback and
869 silc_server_rekey_final.
871 * Removed Tunneled flag from the protocol. Updated the code
872 and the specifications.
874 * Adde `pfs' field to the SilcIDListData to indicate whether
875 the PFS is to be performed in the re-key. Affected file is
878 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
880 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
881 int64 of at least the xintXX size. If void * is less that 4
882 bytes uint32 * will be used. Defined bool as boolean.
884 * Changed _ALL_ unsigned long and unsigned int to uint32,
885 unsgined short to uint16 in the source tree.
887 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
888 not handle clients that has entry->data.registered == FALSE.
889 They are not in the network anymore. Affected file is
892 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
894 * Implemented the sending of the SERVER_SIGNOFF notify in the
895 server. Affected file is silcd/server.c.
897 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
898 Added also silc_notify_payload_encode_args into the
899 lib/silccore/silcnotify.[ch].
901 * Implemented ther SERVER_SIGNOFF notify handling in the server.
902 Affected file silcd/packet_receive.c.
904 * Implemented the SERVER_SIGNOFF notify handling in the client
905 library. Affected file lib/silcclient/client_notify.c. Also,
906 implemnted the printing of the SERVER_SIGNOFF info to the
907 application. Affected file silc/client_ops.c.
909 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
910 if the deleting was successful. Affected file silcd/idlist.[ch].
912 * Added support for public key authentication in the connection
913 authentication protocol in the client library. Affected file
914 lib/silcclient/protocol.c.
916 * Changed the server's silc_idlist_get_clients_by_* interface
917 to support already allocated array so that new entries may be
918 added to pre-allocated array. Affected file silcd/idlist.[ch].
919 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
922 * All command reply functions in the server now calls the
923 pending command callback even if error occured. This way the
924 error will be delivered to the client as well. Affected files
925 silcd/command.c and silcd/command_reply.c.
927 * Fixed INFO command to return local server's info if no server
928 was provided. Affected file lib/silcclient/command.c.
930 * Removed RESTART command for good. Updated the code and the
933 * Rewrote parts of the task system. It is a bit simpler now.
934 Removed unsued task priorities. The affected files are
935 lib/silcutil/silctask.[ch].
937 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
939 * Moved the USERS printing from the library to the application.
940 Affected files lib/silcclient/command.c and silc/client_ops.c.
942 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
946 * Added channel key re-key support. The re-key is perfomed
947 only by the router and is done once in an hour. Added `rekey'
948 field to the SilcChannelEntry in the server. Affected files
949 silcd/server.c and silcd/idlist.h.
951 * Added silc_task_unregister_by_context into the file
952 lib/silcutil/silctask.[ch].
954 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Added SILC_UMODE_GONE mode to indicate when the client is not
957 present in the SILC network. Added also support to the local
958 command AWAY that will set this mode. Added support of showing
959 "xxx is gone" in WHOIS command. The USERS command shows the
962 * Fixed setting server and router operator privileges in the
963 server's UMODE command. Affected file silcd/command.c.
965 * Merged the SKE KE1 and KE2 payloads into one payload. The
966 new KE payload is equivalent to the old KE2 payload.
968 Cleaned up the SKE Start Payload parsing. It now uses the
969 simple buffer unformatting to do the parsing. A lot faster
972 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
973 to the SKE that is used to indicate whether both of the SKE
974 parties should perform authentication. By default only the
975 responder performs authentication. By setting this flag also
976 the initiator must do authentication. By default it is unset
977 since in normal SKE case, client to server connection, only
978 the responder should do authentication. When doing SKE between
979 two clients both should perform authentication. Updated the
980 code and the protocol specs.
982 * A little fix to IDENTIFY command in the server. Search the
983 client first by hash not nickname. Affected file is
986 * Fixed the silc_client_close_connection to support closing
987 the client to client connections wihtout deleting too much
988 data. Affected file lib/silcclient/client.c.
990 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
991 are received if protocol used to be active but is not anymore
992 the application would crash due to NULL pointer dereference.
993 Affected files silcd/server.c and lib/silcclient/client.c.
995 * Added `hash' field to the SilcClientConnection to include
996 the hash function negotiated in the SKE protocol.
998 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
999 to set the channel founder authentication data. A client can
1000 claim the founder rights later by providing the authentication
1001 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1002 This way the channel founder can regain the channel founder
1003 privileges even it is left the channel. This works only on
1004 local server and the client must be connected to the same
1005 server to be able to regain the founder rights. Updated the
1006 protocol specs accordingly.
1008 Added support to the CMODE command in the client to set the
1009 founder auth data. Read the README to see how to set it.
1011 Added support to the CUMODE command to claim the founder
1012 rights. Read the README to see how to do it.
1014 Added support for the founder authentication to the Channel
1015 Entry in the server. Affected file silcd/idlist.h.
1017 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1018 server's CMODE command. Affected file silcd/command.c.
1020 * Added the following new functions into lib/silccore/silcauth.[ch]:
1021 silc_auth_get_method and silc_auth_get_data.
1023 * The server now saves the remote hosts public key to the
1024 SilcIDListData pointer. Affected file silcd/protocol.c.
1026 * The normal server now does not remove the channel entry from
1027 the cache if the founder authentication data is set. It used
1028 to remove it if the founder was the last one on the channel on
1029 the server and left the channel. The auth data is saved and
1030 if the channel is re-joined later the old entry is used with
1031 the old auth data. Affected files silcd/command_reply.c and
1034 * Removed the `pkcs' field from the SilcIDListData structure
1035 in the server; it is not used. Affected file silcd/idlist.h.
1037 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1039 * Fixed packet processing on slow links. Partial packets were
1040 never re-processed because the incoming data buffer was cleared
1041 by the application. Application must not directly clear the
1042 sock->inbuf, the packet processing routines handle it. Fixed
1043 this in client library and in server.
1045 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1047 * Fixed the WHOIS and IDENTIFY send reply function to really
1048 check whether to send list or just one entry. Affected file
1051 * Cleaned up the LEAVE command's channel key distribution. The
1052 affected file silcd/command.c.
1054 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1055 can enforce the channel mode as well. In that case the ID
1056 includes the ID of the server. The code now enforces the
1057 mode change if the router have different mode than the server.
1059 * The notify client operation with CMODE_CHANGE notify can now
1060 return NULL client_entry pointer if the CMODE was not changed
1061 by client. Application must check for this.
1063 * Added <Server ID> argument to INFO command to support server
1064 info fetching by Server ID.
1066 * Added silc_server_announce_get_channel_users to get assembled
1067 packets of channel users of the specified channel. Affected
1068 file silcd/server.[ch].
1070 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1071 was freed underneath the ID Cache.
1073 * Re-announce clients when the server received CHANNEL_CHANGE
1074 notify from the router. Affected file silcd/packet_send.c.
1076 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1078 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1079 crashed since it did not handle the fact that there is no cipher
1080 called "3" and didn't check the error condition. Now fixed.
1082 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1083 flag. It can be used to send message requests.
1085 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1087 * Implemented the RESTART command in the client.
1089 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1090 notice type messages. Added notice printing to the user
1093 * The channel keys are not re-generated if the channel's mode
1094 is PRIVKEY, ie private key on the channel exists. Affected
1095 files silcd/server.c and silcd/command.c.
1097 * Fixed a little bug in channel message delivery when channel
1098 private keys are set in the server. Affected file is
1099 silcd/packet_send.c.
1101 * Changed the setting on channel->on_channel = TRUE from the
1102 silc_client_save_channel_key to the JOIN command reply. The
1103 key payload is not received if the private channel key is set.
1104 Affected file lib/silcclient/command_reply.c and the
1105 lib/silcclient/client_channel.c.
1107 * When the CMODE_CHANGE notify is sent and the channel private
1108 key mode is removed the channel key must be re-generated in
1109 other cells as well. Added this support for the router in the
1110 silcd/packet_receive.c.
1112 * Added new local command NOTICE to send notice message on
1113 channel. Affected file silc/local_command.[ch].
1115 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Added new local command ME to the client. It is used to send
1118 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1119 some action. Affected file silc/local_command.[ch].
1121 * Changed channel_message and private_message client operations
1122 to deliver the message flags to the application. Added also
1123 the `flags' arguments to the silc_client_send_channel_message
1124 and silc_client_send_private_message functions. Affected file
1127 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1129 * Redefined the Private Message Payload to support private message
1130 keys and to support the new private message flags. Updated
1131 the protocol specs. Flags makes it possible to have for example
1132 CTCP style messages.
1134 * Added new type SilcPrivateMessagePayload and defined an API
1135 for it in the lib/silcclient/silcprivate.[ch].
1137 * Tested private message private keys successfully. Tested the
1138 private message key set, unset and list commands with the new
1141 * Redefined the Channel Message Payload to include the channel
1142 message flags (equal with private message flags) to support
1143 for example CTCP style messages.
1145 * Defined some of the message (for channel and private message)
1146 flags. Updated the protocol specs and added the flags to the
1147 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1149 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1151 * Added SilcKeyAgreementStatus type to the key agreement routines
1152 to indicate the current status and error if one occured.
1153 The status types are defined in the lib/silcclient/silcapi.h.
1155 * Added new local command KEY that is used to set and unset private
1156 keys for channels, set and unset private keys for private messages
1157 with remote clients and to send key agreement requests and
1158 negotiate the key agreement protocol with remote client. The
1159 key agreement is supported only to negotiate private message keys,
1160 it currently cannot be used to negotiate private keys for channels,
1161 as it is not convenient for that purpose.
1163 * Fixed a minor pending callback setting bug in the function
1164 silc_client_get_client_by_id_resolve, now the function works.
1165 Affected file lib/silcclient/idlist.c.
1167 * Added function silc_net_get_local_port to get local bound
1168 port by socket. Added to lib/silcutil/silcnet.[ch].
1170 * Added `sockets' and `sockets_count' fields to the SilcClient
1171 object. They hold the sockets of the listenning sockets in
1172 the client. Listenning sockets may be for example the key
1173 agreement server. Affected file lib/silcclient/client.[ch].
1174 Added functions the silc_client_add_socket and the
1175 silc_client_del_socket. They are exported to the application
1178 * Added ~./silc/clientkeys to support other client's public keys.
1180 * Renamed verify_server_key client operation to verify_public_key
1181 and added one argument to indicate the type of the connection
1182 (server, client etc.).
1184 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1186 * Added silc_server_connection_auth_request to handle the
1187 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1188 silcd/packet_receive.[ch].
1190 * Added silc_server_send_connection_auth_request into the
1191 silcd/packet_send.c to send the connection auth request packet.
1193 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1196 * Fixed the public key authentication in responder side in the
1197 server. The `auth_data' pointer includes the SilcPublicKey
1198 not the path to the public key. Affected file silcd/protocol.c.
1200 * Implemented the public key authentication in the initiator side
1201 in the server. Affected file silcd/protocol.c.
1203 * Removed the [RedirectClient] config section from the server
1204 configuration. Is not needed and I don't want to implement it.
1206 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1208 * Cleaned up the CMODE command in the server. It now works
1209 correctly and supports all the modes defined in the protocol.
1210 Affected file is silcd/command.c.
1212 * Added `hmac_name' field to the SilcChannelEntry in the server
1213 to hold the default HMAC of the channel. It can be set when
1214 creating the channel (with JOIN command). Affected files
1217 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1218 type to indicate the change of the current cipher and hmac
1219 on the channel. Client can safely ignore the <cipher> argument
1220 (if it chooses to do so) since the CHANNEL_KEY packet will
1221 force the channel key change anyway. The <hmac> argument is
1222 important since the client is responsible of setting the new
1223 HMAC and the hmac key into use.
1225 * Fixed the CMODE command in the client library as well.
1227 * Tested CMODE command in router environment successfully.
1229 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1231 * Show the version of the remote client (or server) when connecting
1232 to the server. It is logged to the log file. Affected file
1233 is silcd/protocol.c.
1235 * Fixed the KILLED notify handling in the client library. The
1236 client must be removed from all channels when receiving the
1239 Also, do not remove the client entry when giving the KILL
1240 command but when the KILLED notify is received.
1242 * Removed silc_idlist_find_client_by_nickname from the server.
1243 Not needed anymore. Affected files silcd/idlist.[ch].
1245 * Implemented the CHANNEL_CHANGE notify type handling to the
1246 server. Affected file silcd/server.c.
1250 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1252 * Added silc_server_send_notify_invite to send the INVITE
1253 notify between routers.
1255 * Implemented the INVITE command correctly to the server.
1257 * Implemented the INVITE notify type handling in the server.
1259 * Implemented the INVITE command to the client library and on the
1262 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1264 * Added function silc_server_get_client_resolve to find the
1265 client entry by ID from all ID lists and then resolve it
1266 (using WHOIS) if it cannot be found. Affected file is
1269 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Implemented the BAN command to the client library.
1273 * The JOIN command in the server now checks the invite list
1276 * Changed the silc_command_reply_payload_encode_va and the
1277 silc_command_payload_encode_va to support that if argument is
1278 NULL it ignores and checks the next argument. Affected file
1279 lib/silccore/silccommand.c.
1281 * Added silc_server_send_notify_ban to send the BAN notify
1282 type between routers.
1284 * Chaned the silc_notify_payload_encode to support that if
1285 argument is NULL it ignores and checks the next argument.
1286 Affected file lib/silccore/silcnotify.c.
1288 * Tested ban lists in router environment successfully.
1290 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1292 * Implemented BAN command to the server, in silcd/command.[ch].
1294 * Removed the BAN and INVITE_LIST modes from the CMODE command
1297 * Added function silc_string_match to regex match two strings.
1298 Affected files lib/silcutil/silcutil.[ch].
1300 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1302 * Redefined parts of the SilcChannelEntry in the server to support
1303 the new ban and invite lists.
1305 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1307 * Redefined the INVITE command. The same command can be used to
1308 invite individuals to the channel but also to manage the invite
1309 list of the channel (to add to and remove from the invite list).
1310 Updated the protocol specs.
1312 * Added new command SILC_COMMAND_BAN that can be used to manage
1313 the ban list of the channel. Updated the protocol specs.
1315 * Removed the channel modes: the SILC_CMODE_BAN and the
1316 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1317 in the CMODE command. The equivalent features are now available
1318 using INVITE and BAN commands. Updated the protocol specs.
1320 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1321 in the network about change in the current ban list. The notify
1322 type is not used by the client.
1324 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1325 support the invite lists.
1327 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1329 * Added new function silc_string_regexify that converts string
1330 including wildcard characters into regex string that can
1331 be used by the GNU regex library. Added into the file
1332 lib/silcutil/silcutil.[ch].
1334 Added silc_string_regex_combine to combine to regex strings
1335 into one so that they can be used as one regex string by
1336 the GNU regex library. Added into the file
1337 lib/silcutil/silcutil.[ch].
1339 Added silc_string_regex_match to match two strings. It returns
1340 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1342 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1344 * Imported GNU regex to the soruce tree into lib/contrib.
1345 Fixed some compiler warning from the regex.c.
1347 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Fixed MOTD command in the server to work in router environment.
1351 * Fixed the MOTD command in the client library to support
1352 the server argument in the command.
1354 * Added `nickname_len' argument to the silc_idlist_add_client
1355 in the server, as the `nickname' argument may be binary data
1358 * Added silc_idlist_get_channels to return all channels from
1361 * Implemented LIST command to the server. Affected file is
1364 * Implemented the LIST command to the client library and on the
1367 * Added [<user count>] argument to the LIST command reply.
1368 With private channels the user count is not shown.
1370 * Updated TODO and README.
1372 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1374 * The client entry's data.registered must be TRUE even with
1375 global client entry on global client list. The data.registered
1376 is used to check whether the client is anymore in the network,
1377 for example with WHOWAS command so it must be valid.
1379 * Fixed the WHOWAS command in the server. It now actually works
1380 in router environment. Added function into silcd/command_reply.c
1381 silc_server_command_reply_whowas_save.
1383 * Added silc_idlist_purge function to the silcd/idlist.c
1384 to periodically purge the ID Cache.
1386 * Fixed INFO command in the server. It works now in router
1387 environment. Added <server name> argument to the INFO command
1388 reply. Updated the protocol specs.
1390 * Fixed minor bug in silc_idcache_purge to not purge if the
1391 expire value is zero.
1393 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1394 they were buggy because of the WHOWAS information.
1396 * Fixed local command MSG to handle the async resolving of
1397 the remote client properly. It used to fail the first MSG.
1398 Affected file silc/local_command.c.
1400 * Added `data_len' field to SilcIDCache context.
1402 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1404 * Update TODO. Todo in commands in the server.
1406 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1408 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1409 used by routers as broadcast packet to inform other routers
1410 about the changed user mode.
1412 Implemented the notify handling in the server. Affected file is
1413 silcd/packet_receive.c. Added the function
1414 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1416 * Added new generic Channel Payload and deprecated the New Channel
1417 Payload. The New Channel Payload is now the generic Channel
1420 * Added new argument `mode' to the silc_server_send_new_channel
1421 as it is required in the Channel Payload now.
1423 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1424 and created a new and real SilChannelPayload to represent the
1425 new generic Channel Payload. Implemented the encode/decode
1426 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1428 * Added silc_server_get_client_channel_list to return the list
1429 of channels the client has joined for WHOIS command reply.
1430 Affected file silcd/server.[ch].
1432 * Implemented the channel list sending in the WHOIS command reply
1433 in server and in the client.
1435 Implemented the channel list displaying on the user interface
1436 as well. Affected file silc/client_ops.c.
1438 * Added silc_channel_payload_parse_list to parse list of Channel
1439 Payloads. It returns SilcDList list of SilcChannelPayloads.
1440 Client for example can use this function to parse the list of
1441 channels it receives in the WHOIS command reply. The caller
1442 must free the list by calling silc_channel_payload_list_free.
1443 Affected files lib/silccore/silcchannel.[ch].
1445 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1447 * Added one new argument <user mode> to the WHOIS command reply
1448 to return the mode of the user in SILC. Updated the protocol
1451 Implemented it to the server and client.
1453 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Fixed the mode printing on the user interface on joining.
1456 Affected file silc/client_ops.c.
1458 * Implemented the UMODE command and user modes in general to the
1459 client library and to the user interface.
1461 * Implemented the UMODE command to the server.
1463 * The server now sends UNKNOWN_COMMAND error status if client sends
1464 unknown command. Affected file silcd/command.c.
1466 * All server commands now handle the command identifier the right
1467 way when sending the command reply to the client. The client can
1468 use to identify the command replies with the identifier.
1470 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1472 * Added silc_server_get_client_route to resolve the route to
1473 the client indicated by the client ID. Affected file is
1476 * Added silc_server_relay_packet as general function to relay
1477 packet to arbitrary destination. This deprecates functions
1478 like _send_private_message_key, _relay_notify etc. Affected
1479 file is silcd/packet_send.[ch].
1481 Removed silc_server_send_key_agreement,
1482 silc_server_send_private_message_key and
1483 silc_server_packet_relay_notify functions from the file
1484 silcd/packet_send.[ch].
1488 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1489 server. Affected file silcd/packet_receive.[ch].
1491 * Implemented the KILL command to the client. Implemented the
1492 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1493 Affected files lib/silcclient/command[_reply].c and
1494 lib/silcclient/client_notify.c. Implemented the KILL notify
1495 printing in the user inteface.
1497 * Fixed a lot silc_parse_nick memory leaks from the client
1498 library in the file lib/silcclient/command.c.
1500 * Changed the silc_server_send_notify_on_channels's `sender'
1501 argument from SilcSocketConnection to SilcClientEntry to
1502 check the sender as entry and not as connection object and not
1503 to send to the client provided as argument. The affected file
1504 is silcd/packet_send.[ch].
1506 * The notify packets that are destined directly to the client used
1507 to not to be processed by the server. Now changed that and the
1508 server processes all notify packets. After relaying the packet
1509 to the client the notify packet is processed in the server.
1511 * The silc_server_free_client_data now checks whether there is
1512 pending outgoing traffic for the client and purges the data to
1513 the network before removing the client entry.
1515 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1517 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1518 an client is killed from the SILC Network. Updated the protocol
1521 Added new function silc_server_send_notify_killed to the
1522 silcd/packet_send.[ch].
1524 * Added function silc_server_packet_relay_notify to relay notify
1525 packets that are destined directly to a client. In this case
1526 the server does not process the notify packets but merely relays
1527 it to the client. Affected file silcd/packet_send.[ch].
1529 Added also silc_server_packet_process_relay_notify to check
1530 whereto relay the notify. Affected file is
1531 silcd/packet_receive.[ch].
1533 * Implemented the KILL command to the server.
1537 * Added the backup schema desgined last fall to the protocol
1538 specs for everyone to see. The specification is in the
1539 *-spec-xx.txt draft and the packet type definitions for the
1540 backup routers is in *-pp-xx.txt draft. Thusly, added also
1541 new packet type SILC_PACKET_CELL_ROUTERS.
1543 * A big security problem in the implementation discovered. The
1544 signoff of an client did not cause new channel key generation
1545 which it of course should've done. The channel keys must be
1546 always re-generated when client leaves (or signoffs) the channel.
1547 The silc_server_remove_from_channels funtion now handles
1548 the channel key re-generation.
1550 * Added `sender' argument to the silc_server_send_notify_on_channels
1551 to not to send the client provided as argument. Affected file
1552 silcd/packet_send.[ch].
1554 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1556 * Implemented OPER and SILCOPER commands into the server and
1559 * Added silc_auth_verify and silc_auth_verify_data to verify
1560 the authentication directly from the authentication payload.
1561 It supports verifying both passphrase and public key based
1562 authentication. Affected file lib/silccore/silcauth.[ch].
1564 * Added `hash' field to the SilcIDListData structure. It is the
1565 hash negotiated in the SKE protocol. Affected file is
1568 * Slight redesigning of the SilcAuthPayload handling routines.
1569 Do not send SilcPKCS but SilcPublicKey as argument.
1571 * Implemented the public key authentication support to the
1572 serverconfig. The public key is loaded from the provided path
1573 and saved as authentication data to void * pointer. Thus,
1574 changed the unsigned char *auth_data to void *auth_data;
1576 * Fixed SHUTDOWN command to send the reply before the server
1577 is shutdown. :) Affected file silcd/command.c.
1579 * Fixed fatal bug in CONNECT command. The hostname was invalid
1580 memory and server crashed. Affected file silcd/command.c.
1582 * Fixed fatal bug in CLOSE command. The server_entry became
1583 invalid but was referenced later in the command. Affected file
1586 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1588 * Fixed fatal bug in failure packet handling. Server ignored
1589 the failure and thus crashed when it came.
1593 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1596 that the command may be executed only once in (about) 2 seconds.
1597 The old SILC_CF_LAG flag is same but allows command bursts up
1598 to five before limiting.
1600 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1601 server code. Various commands now includes the CF_LAG_STRICT
1602 flag to disallow any kind of miss-use of the command.
1604 * Fixed the silc_buffer_unformat to not to allocate any data
1605 if the length of the data is zero. It used to allocate the
1606 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1608 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Changed the format of AdminConnection configuration section
1611 in the server. Added username of the admin to the format.
1612 Affected files silcd/serverconfig.[ch].
1614 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1615 to return admin configuration data by host, username and/or
1618 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1620 * Implemented WHOWAS command to the server. Added the functions:
1622 silc_server_command_whowas_parse,
1623 silc_server_command_whowas_send_reply,
1624 silc_server_command_whowas_from_client and
1625 silc_server_command_whowas_from_server
1627 * Added <Client ID> argument to the WHOWAS command reply. Updated
1628 the protocol specs accordingly.
1630 * Implemented WHOWAS command and command_reply to the client
1633 Implemented the WHOWAS printing on the user interface.
1635 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1637 * Added new argument to the WHOWAS command reply, the real name.
1638 It is an optional argument. Updated the protocol specs.
1640 * Added SilcIDCacheDestructor callback that is registered when
1641 the SilcIDCache is allocated. The callback is called when
1642 an cache entry in the ID Cache expires, or is purged from the
1643 cache. Added into lib/silccore/idcache.[ch].
1645 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1646 to destruct the client entries when the cache entry expires.
1647 Other ID Cache's in server and in the client library ignores
1650 * If the ID Cache entry's `expire' field is zero then the entry
1651 never expires. Added boolean `expire' argument to the
1652 silc_idcache_add function in the lib/silccore/idcache.[ch].
1653 If it is TRUE the default expiry value is used.
1655 * Added silc_server_free_client_data_timeout that is registered
1656 when client disconnects. By default for 5 minutes we preserve
1657 the client entry for history - for WHOWAS command.
1659 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1661 * Added support to the server to enforce that commands are not
1662 executed more than once in 2 seconds. If server receives
1663 commands from client more frequently, timeout is registered
1664 to process the commands. Affected file silcd/command.c.
1665 Added new function silc_server_command_process_timeout.
1667 * Changed NICK_NOTIFY handling in client library to check that
1668 if the client's nickname was changed, so there is no need to
1669 resolve anything from the server.
1671 * Removed error printing from the WHOIS and IDENTIFY commands.
1672 If error occurs then it is ignored silently in the client library.
1673 The application, however, may map the received error to
1674 human readable error string. The application currently maps
1675 the NO_SUCH_NICKNAME error to string.
1677 * Made the command status message public to the application. Moved
1678 them from lib/silcclient/command_reply.c to
1679 lib/silcclient/command_reply.h. The application can map the
1680 received command status to the string with the
1681 silc_client_command_status_message function.
1683 * Added check to the server to check that client's ID is same
1684 as the Source ID in the packet the client sent. They must
1687 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1689 * Added dist-bzip hook to the Makefile.am to make bzip2
1690 compressed distributions.
1692 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * Server now enforces the maximum length for the nickname and
1695 the channel as protocol specification dictates. 128 bytes for
1696 nickname and 256 bytes for channel name.
1698 * Moved the WHOIS printing to the application. The client libary
1699 does not print out the WHOIS information anymore, the application
1700 must do it. Renamed silc_client_command_reply_whois_print to
1701 the silc_client_command_reply_whois_save.
1703 The client's idle time is also sent to the application now, and
1704 the idle is shown on screen.
1706 * Added silc_client_command_reply_identify_save to save the
1707 received IDENTIFY entries.
1709 * Do not check for channel private keys in message sending and
1710 reception if the channel does not have the PRIVKEY mode set.
1711 Affected file lib/silclient/client_channel.c.
1713 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1716 just surfaced after chaning the JOIN procedure.
1718 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * Added silc_client_get_clients_by_list to get client entries
1721 from Client ID list, that is returned for example by JOIN
1722 and USERS command replies. The application should use this
1723 function for example when JOIN command reply is received to
1724 resolve the clients already on the channel (library does not
1725 do that anymore as USERS command reply is not used in the JOIN
1726 procedure anymore). Affected files lib/silcclient/silcapi.h and
1727 lib/silcclient/idlist.c.
1729 * JOIN command reply and USERS command reply returns now SilcBuffer
1730 pointers instead of unsigned char pointers when returning
1731 the client list and mode list.
1733 * Added <Client ID> argument to the JOIN command reply, mainly
1734 for the server to identify for which client the command was
1735 originally sent. Updated protocol specs accordingly.
1737 * Added SilcDlist private_key pointer to the SilcChannelEntry
1738 in the client to support the channel private keys. Affected
1739 file is lib/silcclient/idlist.h.
1741 * Added SilcChannelPrivateKey argument to the function
1742 silc_client_send_channel_message so that application can choose
1743 to use specific private ke if it wants to. If it is not provided,
1744 the normal channel key is used, unless private keys are set.
1745 In this case the first (key that was added first) is used
1746 as the encryption key.
1748 * Implemented the support for channel private key handling.
1749 Implemented the following functions:
1751 silc_client_add_channel_private_key,
1752 silc_client_del_channel_private_keys,
1753 silc_client_del_channel_private_key,
1754 silc_client_list_channel_private_keys and
1755 silc_client_free_channel_private_keys
1757 Affected file lib/silcclient/client_channel.c.
1759 * Added the support for the private keys in the channel message
1760 sending and encryption and in the message reception and
1761 decryption. Affected funtions are
1762 silc_client_send_channel_message and silc_client_channel_message.
1764 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1766 * Added SKE's key verify callback to the client library's
1767 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1769 * Removed the statement that server (or router) must send USERS
1770 command reply when joining to the channel so that the client
1771 knows who are on the channel. Instead, the client list and
1772 client's mode list is now sent in the JOIN command reply to the
1773 client who joined channel. This is better solution.
1775 * Added function silc_server_get_users_on_channel and function
1776 silc_server_save_users_on_channel to the silcd/server.[ch].
1778 * Removed function silc_server_command_send_users from the
1781 * Do not show topic on the client library anymore. The topic is
1782 sent in the command reply notify to the application and the
1783 application must show the topic now.
1785 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1787 * Added client searching by nickname hash into the IDENTIFY and
1788 WHOIS commands in the server as they were clearly missing from
1789 them. Affected file is silcd/command.c.
1791 * Fixed a bug in private message receiving in the client library.
1792 The remote ID was freed and it wasn't supposed, now it is
1795 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1797 * Minor fix to the channel payload; allocate the data area, as it
1798 needs to be of specific length.
1800 * If the key agreement port is zero then the operating
1801 system will define the bound port. Affected files are
1802 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1804 * Added new function silc_channel_payload_decrypt into the file
1805 lib/silccore/silcchannel.[ch].
1807 * Moved the channel message etc, check from silc_packet_decrypt
1808 to applications. The library calls now a generic
1809 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1810 when the packet is either normal or special. This was done to
1811 allow more wide range of checking that was not allowed when
1812 the code was in library. Now applications can do virtually any
1813 checks to the packet and return to the library the decision how
1814 the packet should be processed. Affected files are
1815 lib/silccore/silcpacket.[ch].
1817 Added silc_server_packet_decrypt_check to the server and
1818 silc_client_packet_decrypt_check to the client library.
1820 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1821 to send with specified source and destination information.
1823 * Channel message delivery between routers was broken after the
1824 channel key distribution was fixed earlier. The channel key
1825 was used be to distributed to other routers as well which is not
1826 allowed by the protocol. Now this is fixed and channel keys
1827 really are cell specific and the channel message delivery between
1828 routers comply with the protocol specification.
1830 * Fixed various commands in server to check also the global list
1831 for the channel entry and not just the local list. The affected
1832 file silcd/command.c.
1834 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1836 * Added assert()s to buffer formatting and unformatting routines
1837 to assert (if --enable-debug) when error occurs. Affected
1838 file: lib/silcutil/silcbuffmt.c.
1840 * Changed to auto-reconnect to check whether the remote host is
1841 router and register the re-connect timeout if it is. It used
1842 to check that whether we are normal server, but router must do
1843 auto-reconnect with another router as well. Affected file
1846 * Removed the [<key len>] option from CMODE command as the cipher
1847 name decides the key length, nowadays. See the defined ciphers
1848 from the protocol specification.
1850 * Added [<hmac>] option to the CMODE command to define the HMAC
1851 for the channel. Added SILC_CMODE_HMAC channel mode.
1853 * Added [<hmac>] option for the JOIN command so that user can
1854 select which HMAC is used to compute the MACs of the channel
1857 * Added Hmac field to the Channel Message Payload. The integrity
1858 of plaintext channel messages are now protected by computing
1859 MAC of the message and attaching the MAC to the payload. The
1860 MAC is encrypted. Now, it is clear that this causes some
1861 overhead to the size of the packet but rationale for this is that
1862 now the receiver can verify whether the channel message decrypted
1863 correctly and also when private keys are set for the channel the
1864 receiver can decrypt the packet with several keys and check from
1865 the MAC which key decrypted the message correctly.
1867 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1868 lib/silccrypt/silccipher.[ch].
1870 * Added silc_hash_len to return the digest length into the
1871 lib/silcrypt/silchash.[ch].
1873 * Rewrote parts of Silc Channel Payload interface in the
1874 lib/silccore/silcchannel.[ch]. The encode function now also
1875 encrypts the packet and parse function decrypts it.
1877 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1879 * Fixed a minor formatting bug in the SKE's key material processing.
1880 It actually might have processed the keys wrong way resulting
1883 * Redefined the mandatory HMAC algorithms and added new algorithms.
1884 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1885 and hmac-md5 truncated to 96 bits. The mandatory is now
1886 hmac-sha1-96. Rest are optional (including the one that used
1887 to be mandatory). Rationale for this is that the truncated HMAC
1888 length is sufficient from security point of view and can actually
1889 make the attack against the HMAC harder. Also, the truncated
1890 HMAC causes less overhead to the packets. See the RFC2104 for
1893 * Added new [hmac] configuration section. The SKE used to use
1894 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1895 is of course wrong. The official names that must be proposed in
1896 the SKE are the ones defined in the protocol specification
1897 (hmac-sha1-96 for example). The user can configure any hmac
1898 using any hash function configured in the [hash] section. At
1899 least, the mandatory must be configured.
1901 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1903 * Added HMAC list to the SKE proposal list. It has now both
1904 hash algorithm list and HMAC list. This makes the protocol
1905 incompatible with previous versions. The SKE now seems to work
1906 the way it is supposed to work, for the first time actually.
1908 * Defined plain Hash algorithms to the protocol specification.
1911 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1913 * Implemented support for key agreement packets into the server.
1914 Added functions silc_server_key_agreement and
1915 silc_server_send_key_agreement. Other than these functions,
1916 server has nothing to do with this packet.
1918 * Added support for private message key packets into the server.
1919 Added functions silc_server_private_message_key and
1920 silc_server_send_private_message_key.
1924 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1925 called in the protocol's final callback instead in the END
1926 protocol state. This makes a little more sense and in the same
1927 time in client we can use the same protocol routines for normal
1928 key exchange and to key agreement packet handling as well.
1930 * Added to both client's and server's KE protocol context the
1931 SilcSKEKeyMaterial pointer to save the key material. We will
1932 bring the key material to the protocol's final callback by doing
1933 this. The final callback must free the key material.
1935 * Added SKE's packet_send callback into client's KE protocol
1936 context so that the caller can choose what packet sending function
1937 is used. This way we can use different packet sending when
1938 doing normal SKE when doing key agreement packet handling (in
1939 the key agreement packet handling we do not want to encrypt
1942 * Implemented the responder side of the key agreement routines
1943 in the client. The client can now bind to specified port and
1944 accept incoming key negotiation. The key material is passed
1945 to the application after the protocol is over.
1947 * Implemented the processing of incoming Key Agreement packet
1948 in the client. Added function silc_client_key_agreement to
1951 * Implemented the intiator side of the key agreement routines
1952 in the client. The client can now initiate key agreement with
1953 another remote client. The key material is passed to the
1954 application after the protocol is over.
1956 * Created client_keyagr.c to include all the key agreement
1959 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1960 SILC_TASK_CALLBACK except that it is not static.
1962 * Created client_notify.c and moved the Notify packet handling
1963 from the client.[ch] into that file.
1965 * Created client_prvmsg.c and moved all private message and
1966 private message key routines from the client.[ch] into that file.
1968 * Create client_channel.c and moved all channel message and
1969 channel private key routines from the client.[ch] into that file.
1971 * Changed silc_client_get_client_by_id_resolve to resolve with
1972 WHOIS command instead of IDENTIFY command, in the file
1973 lib/silclient/idlist.c.
1975 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1977 * Implemented the SKE's responder side to the Client library.
1979 * When FAILURE is received to the protocol do not trust it
1980 blindly. Register a timeout to wait whether the remote closes
1981 the connection as it should do it, only after that process the
1982 actual failure. This was changed to both client and server.
1984 * Added client_internal.h to include some of the structures
1985 there instead of client.h in lib/silcclient/.
1987 * Added function silc_task_unregister_by_callback to unregister
1988 timeouts by the callback function.
1990 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1992 * Some "Incomplete WHOIS info" errors has been appearing on the
1993 log files. Took away the entry->userinfo check from WHOIS
1994 reply sending. The entry->userinfo is now " " if client did not
1995 provide one. I thought this was fixed earlier but something
1996 is wrong still. Let's see if the error still appears.
1998 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2000 * Fixed a minor bug in the login when the channel key is
2001 re-generated in the server. It used to generate the key in
2002 wrong order and thus caused problems in the channel traffic.
2004 * Fixed a minor bug in channel key distsribution after
2005 KICK command. The key was not sent to the router even though
2008 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2010 * Added silc_ske_process_key_material_data as generic routine
2011 to process any key material as the SILC protocol dictates. The
2012 function is used by the actual SKE library but can be used by
2013 applications as well. This relates to the private message keys
2014 and the channel private keys since they must be processed the
2015 same way the normal SILC session keys. The protocol dictates
2016 this. Affected files: lib/silcske/silcske.[ch].
2018 Added also silc_ske_free_key_material to free the
2019 SilcSKEKeyMaterial structure.
2021 * Defined silc_cipher_set_key function to set the key for
2022 cipher without using the object's method function. The affected
2023 files: lib/silccrypt/silccipher.[ch].
2025 * Implemented silc silc_client_add_private_message_key,
2026 silc_client_add_private_message_key_ske,
2027 silc_client_del_private_message_key,
2028 silc_client_list_private_message_keys and
2029 silc_client_free_private_message_keys functions in the
2032 Added functions silc_client_send_private_message_key to send
2033 the Private Message Key payload and silc_client_private_message_key
2034 to handle incoming Private Message Key payload.
2036 * Added Cipher field to the Private Message Key payload to set
2037 the cipher to be used. If ignored, the default cipher defined
2038 in the SILC protocol (aes-256-cbc) is used.
2040 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2042 * Removed lib/silcclient/ops.h file.
2044 Redefined parts of the SILC Client Library API. Created new
2045 file silcapi.h that deprecates the ops.h file and defines the
2046 published Client Library API. Defined also private message key
2047 API and channel private key API into the file.
2049 This is the file that the application must include from the
2050 SILC Client Library. Other files need not be included by
2051 the application anymore.
2053 * Added new key_agreement client operation callback and also
2054 defined the Key Agreement library API for the application.
2056 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2059 is used by clients to request key negotiation between another
2060 client in the SILC network. If the negotiation is started it
2061 is performed using the SKE protocol. The result of the
2062 negotiation, the secret key material, can be used for example
2063 as private message key.
2065 Implemented the Key Agreement payload into the files
2066 lib/silccore/silauth.[ch].
2068 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2070 * Redefined ciphers for the SILC protocol. Added some new ciphers
2071 and defined the key lengths for the algorithms. Changed the
2072 code accordingly. The default key length is now 256 bits.
2074 * Fixed SKE key distribution function silc_ske_process_key_material
2075 when the key length is more than 128 bits. The default key
2076 length in SILC is now 256 bits.
2078 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2079 to indicate unsupported algorithm.
2081 * Renamed rijndael.c to aes.c and all functions as well.
2083 * Fixed a long standing channel key setting bug in client library.
2084 Weird that it has never surfaced before.
2086 * Fixed bug in channel deletion. If the entire channel is removed
2087 then it must also delete the references of the channel entry
2088 from the client's channel list as the client's channel entry and
2089 the channel's client entry share same memory.
2091 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2093 * Implemented CONNECT and SHUTDOWN commands in the client.
2095 * Implemented CLOSE command to the client.
2097 * Added the function silc_idlist_find_server_by_name into the
2098 files silcd/idlist.[ch].
2100 Added the function silc_idlist_find_server_by_conn into the
2101 files silcd/idlist.[ch].
2103 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2105 * DIE command was renamed to SHUTDOWN. Updated the both code
2108 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2109 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2111 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2114 * Added function silc_server_create_connection function to create
2115 connection to remote router. My server implementation actually
2116 does not allow router to connect to normal server (it expects
2117 that normal server always initiates the connection to the router)
2118 so the CONNECT command is only good for connecting to another
2121 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2123 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2124 or some other client was kicked from the channel.
2126 Implemented the handling of the notify type to both client
2129 Implemented silc_server_send_notify_kicked to send the KICKED
2130 notify. It is used to send it to the server's primary router.
2132 * Implemented the KICK command into server and client.
2134 * Added `query' argument to the silc_idlist_get_client function
2135 to indicate whether to query the client from server or not if
2138 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2139 to indicate that the client is not channel founder.
2143 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2145 * Removed the rng context from SilcPacketContext structure and
2146 changed that the packet routine uses the Global RNG API.
2148 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2150 * Added support for quit message that client can "leave" on the
2151 channel when it quits the SILC. It is ditributed inside the
2152 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2154 Added silc_server_free_client_data that will take the
2155 signoff message as argument.
2157 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2159 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2161 * Updated parts of the protocol specification to keep it up
2164 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2166 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2167 payloads in one packet.
2169 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2170 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2171 use now the new List flag.
2173 * Also deprecated the following packet types: REPLACE_ID,
2174 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2176 * Added list support for Notify packet in server.
2178 * Added silc_server_send_notify_channel_change to send the
2179 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2180 the silc_server_send_replace_id.
2182 * Added silc_server_send_notify_nick_change to send the
2183 NICK_CHANGE notify type. Deprecates the function
2184 silc_server_send_replace_id.
2186 * Added silc_server_send_notify_join to send the JOIN notify type.
2187 Deprecates the function silc_server_send_new_channel_user.
2189 * Added silc_server_send_notify_leave to send LEAVE notify type.
2190 Deprecates the function silc_server_send_remove_channel_user.
2192 * Added silc_server_send_notify_cmode and
2193 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2194 types. Deprecates the silc_server_send_set_mode function.
2196 * Added SERVER_SIGNOFF notify type to indicate that server has
2197 quit. This means that all clients on the channel from that
2198 server will drop. This can be also used when netsplit happens.
2200 Deprecated REMOVE_ID packet type since it is not needed anymore
2203 Added silc_server_send_notify_server_signoff to send the
2204 SERVER_SIGNOFF notify type. Deprecates the function
2205 silc_server_send_remove_id.
2207 Added also silc_server_send_notify_signoff to send the
2208 SIGNOFF notify type.
2210 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2211 SILC protocol from this day on. Changed the protocol
2212 specification as well.
2214 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2215 notify type. It is used between routers to notify about
2216 topic changes on a channel.
2218 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2221 * Partly updated the protocol specification to comply with the
2222 changes now made. It is still though a bit outdated.
2224 * The JOIN notify type now takes one extra argument <Channel ID>.
2225 The packet used to be destined to the channel but now the
2226 JOIN type may be sent as list thus it is impossible to
2227 destine it to any specific channel. By adding this argument
2228 it is again possible.
2230 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2232 * Added CREDITS file. The CHANGES and CREDITS file will appear
2233 in the distribution as well.
2235 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2237 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2238 types in the server's silcd/packet_receive.c.
2240 * Implemented CMODE and CUMODE to work in router environment.
2242 * Fixed minor encoding and decoding buglet from the
2243 lib/silccore/silcmode.c.
2245 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2248 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2250 * Changed all SilcConfigServer* and silc_config_server* to
2251 SilcServerConfig* and silc_server_config*, respectively.
2254 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2256 * Associated the ID (client or server ID) to the Authentication
2257 Payload to avoid any possibility of forging. Updated the
2258 protocol specification and the code accordingly.
2260 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2262 * The RSA key length is now save to the RsaKey context in the
2263 key generation process in lib/silccrypt/rsa.c. The key length
2264 is now used to figure out the maximum size of the block allowed
2265 to be encrypted/signed.
2267 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2268 is equivalent to the silc_mp_mp2bin but does not allocate any
2271 * Changed silc_mp_mp2bin API to take length argument. If it is
2272 non-zero then the buffer is allocated that large. If zero, then
2273 the size is approximated using silc_mp_sizeinbase, which however
2276 * Created Global RNG API which is global RNG that application can
2277 initialize. After initializing, any routine anywhere in the
2278 code (including library) can use RNG without allocating a new
2279 RNG object. This was done to allow this sort of use of the
2280 RNG in code that has no chance to allocate RNG object. All
2281 applications currently allocate this and many routines in the
2282 library use this. Affected file lib/silccrypt/silcrng.[ch].
2284 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2285 it to use the Global RNG API.
2287 * Defined Authentication Payload into protocol specification that
2288 is used during SILC session to authenticate entities. It is
2289 used for example by client to authenticate itself to the server
2290 to obtain server operator privileges.
2292 Implemented this payload into the lib/silccore/silcauth.[ch].
2293 Implemented also routines for public key based authentication
2294 as the new protocol specification dictates.
2296 Moved definitions of different authentication methods from
2297 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2299 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2300 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2301 silc_pkcs_verify_with_hash functions into the file
2302 lib/silccrypt/silcpkcs.[ch].
2304 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2306 * The client entry's userinfo pointer must be always valid.
2307 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2308 will fail since it requires the userinfo. Now, the userinfo
2309 is allocated as "" if actual userinfo does not exist. Actually,
2310 it must exist and it is totally Ok to drop client connections
2311 that does not announce the userinfo. However, we will make
2312 this workaround for now.
2314 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2315 to return the remote port by socket.
2317 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2319 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2320 SILC_SERVER_PENDING_EXEC and added an new macro
2321 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2322 data or when error occurs while processing the pending command.
2324 Added new argument `destructor' into silc_server_command_pending
2325 and to the SilcServerCommandPending object. This destructor is
2326 now called after calling the pending callback or if error occurs
2327 immediately. If error occurs the actual pending callback won't
2328 be called at all - only the destructor. The destructor may be
2329 NULL if destructor is not needed.
2331 All this applies for client library code as well. Similar
2332 changes were made there as well for the pending commands.
2334 In the client, the application must now allocate the
2335 SilcClientCommandContext with the silc_client_command_alloc
2338 * Added reference counter to the SilcServerCommandContext. Added
2339 function silc_server_command_alloc and silc_server_command_dup
2342 Same type of functions added to the client library for the same
2345 * Removed the cmd_ident from IDListData away since it is now
2346 global for all connections. It is the command identifier used
2347 in command sending and with pending commands. The affected file
2350 * Added reference counter to the SilcSocketConnection objecet to
2351 indicate the usage count of the object. The object won't be
2352 freed untill the reference counter hits zero. Currently only
2353 server uses this, and client ignores it. The client must be
2354 set to use this too later. The affected files are
2355 lib/silccore/silcsockconn.[ch]. Added also the function
2356 silc_socket_dup to increase the reference counter.
2358 This was mainly added because it is possible that the socket
2359 is removed underneath of pending command or other async
2360 operation. Now it won't be free'd and proper DISCONNECTING
2361 flags, etc. can be set to avoid sending data to connection that
2362 is not valid anymore.
2364 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2365 the connection. After that it sets SILC_SET_DISCONNECTED.
2366 It is, however, possible that the socket data is not still freed.
2367 The silc_server_packet_process now checks that data is not
2368 read or written to connection that is DISCONNECTED. The socket
2369 get's freed when the reference counter hits zero.
2371 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2373 * Changed the client operation API: channel_message operation's
2374 `sender' is now the client entry of the sender, not the nickname
2375 and the `channel' is the channel entry, not the channel name.
2377 In the private_message operation the `sender' is now also the
2378 client entry of the sender not the nickname.
2380 Affected file is lib/silcclient/ops.h and all applications
2381 using the client operations.
2383 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2385 * Moved the calling of ops->connect() from connect_to_server_final
2386 into receive_new_id functin since that is the point when the
2387 client is actually allowed to send traffic to network. The
2388 affected file is lib/silcclient/client.c.
2390 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2392 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2393 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2394 (if needs broadcasting) instead of broadcasting the packets one
2395 by one which would make a burst in the network traffic.
2397 * Added `broadcast' argument to the functions in silcd/server.[ch]
2398 silc_server_create_new_channel[_with_id] to indicate whether
2399 to send New Channel packet to primary router.
2401 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2403 * Added new function into the silcd/server.[ch] files:
2404 silc_server_create_new_channel_with_id to create new channel with
2405 already existing Channel ID.
2407 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2408 lib/silccore/silcpacket.h. This packet is used t send list of
2409 Set Mode payloads inside one packet. Server uses this to set
2410 the modes for the channels and clients on those channels, that it
2411 announced to the router when it connected to it. The protocol
2412 specification has been updated accordingly.
2414 * The silc_server_new_channel did not handle the packet coming
2415 from normal server as it normally does not send that. However,
2416 when it announces its channels it does send it. Implemented
2417 the support for that.
2419 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2420 into the file lib/silccore/id.h.
2422 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2424 * Fixed memory leaks in the functions silc_idlist_del_client,
2425 silc_idlist_del_channel and silc_idlist_del_server in the file
2426 silcd/idlist.c. All of those leaked like a sieve.
2428 * Fixed some small memory leaks in the client's function
2429 silc_client_notify_by_server.
2431 * Added functions into silcd/server.c: silc_server_announce_clients,
2432 silc_server_announce_channels and silc_server_announce_server.
2433 These functions are used by normal and router server to announce
2434 to its primary router about clients, channels and servers (when
2435 router) that we own. This is done after we've connected to the
2438 These functions effectively implements the following packet types:
2439 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2440 and SILC_PACKET_NEW_ID_LIST.
2442 * Added new functions into the silcd/packet_receive.[ch]:
2443 silc_server_new_id_list, silc_server_new_channel_list and
2444 silc_server_new_channel_user_list to handle the incoming
2445 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2447 * Added support of changing Channel ID in the function
2448 silc_server_replace_id. If the server that announces a channel
2449 to the router already exists in the router (with same name but
2450 with different Channel ID), router is responsible to send
2451 Replace ID packet to the server and force the server to change
2452 the Channel ID to the one router has.
2454 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2455 client that the Channel ID has been changed by the router. The
2456 normal server sends this to the client. Client must start using
2457 the new Channel ID as the channel's ID.
2459 Implemented handling of this new type into lib/silcclient/client.c
2460 into the function silc_client_notify_by_server.
2462 * Added new function silc_idlist_replace_channel_id into the files
2463 silcd/idlist.[ch] to replace the Channel ID.
2465 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2467 * Call silc_server_command_identify_check always when processing
2468 the IDENTIFY command in silcd/command.c
2470 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2472 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2473 send keepalive packets. The packet can be sent by clients,
2474 servers and routers.
2476 Added function silc_socket_set_heartbeat into the file
2477 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2478 If not set, the heartbeat is not performed. The actual
2479 heartbeat is implemented in the low level socket connection
2480 library. However, application is responsible of actually
2483 Added silc_server_send_heartbeat to send the actual heartbeat
2484 packet into silcd/packet_send.[ch]. Server now performs
2485 keepalive with all connections.
2487 * Added silc_task_get_first function into lib/silcutil/silctask.c
2488 to return the timeout task with shortest timeout. There was a bug
2489 in task unregistration that caused problems. TODO has been
2490 updated to include that task system must be rewritten.
2492 * The client library will now resolve the client information when
2493 receiving JOIN notify from server for client that we know but
2494 have incomplete information.
2496 * Rewrote parts of silc_server_remove_from_channels and
2497 silc_server_remove_from_one_channel as they did not remove the
2498 channel in some circumstances even though they should've.
2500 * Encryption problem encountered in server:
2502 The LEAVE command used to send the Channel Key packet to the
2503 router immediately after generating it. However, the code
2504 had earlier sent Remove Channel user packet but not immediately,
2505 ie. it was put to queue. The order of packets in the router
2506 was that Channel Key packet was first and Remove Channel User
2507 packet was second, even though they were encrypted in the
2508 reverse order. For this reason, MAC check failed. Now, this
2509 is fixed by not sending the Channel Key packet immediately but
2510 putting it to queue. However, this is more fundamental problem:
2511 packets that are in queue should actually not be encrypted
2512 because packets that are sent immediately gets encrypted
2513 actually with wrong IV (and thus MAC check fails). So, packets
2514 that are in queue should be encrypted when they are sent to
2515 the wire and not when they put to the queue.
2517 However, the problem is that the current system has not been
2518 designed to work that way. Instead, the packet is encrypted
2519 as soon as possible and left to the queue. The queue is then
2520 just purged into wire. There won't be any fixes for this
2521 any time soon. So, the current semantic for packet sending
2524 o If you send packet to remote host and do not force the send
2525 (the packet will be in queue) then all subsequent packets to the
2526 same remote host must also be put to the queue. Only after the
2527 queue has been purged is it safe again to force the packet
2530 o If you send all packets immediately then it safe to send
2531 any of subsequent packets through the queue, however, after
2532 the first packet is put to queue then any subsequent packets
2533 must also be put to the queue.
2535 Follow these rules and everything works fine.
2537 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2539 * Added new function silc_server_remove_clients_by_server to
2540 remove all client entries from ID list when the server connection
2541 is lost. In this case it is also important to invalidate all
2542 client entires as they hold the invalid server entry. This
2543 fixes fatal bug when server has lost connection and will reconnect
2546 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2548 * Made some sanity checks to silc_server_daemonise like to check
2549 whether the requested user and group actually exists.
2551 * Added sanity check to SKE's silc_ske_responder_finish to check
2552 that the public and private key actually is valid.
2554 * Invalidate the client's nickname when receiving Replace ID
2555 packet and the Client ID is being replaced. This means that the
2556 server will query the nickname if someone needs it (client)
2559 * Sort the ID Cache in client library when the ID Cache data
2560 has changed (needs sorting).
2562 * Do not allow for SILC client to create several connections to
2563 several servers. The client does not support windows right now
2564 and generating multiple connections causes weird behaviour.
2566 Irssi-silc client does support windows and can handle several
2567 connections without problems, see: www.irssi.org and SILC plugin.
2569 * Fixed some places where client was added to the IDList. The
2570 rule of thumb is following (in order to get everything right):
2571 If the client is directly connected local client then the
2572 `connection' argument must be set and `router' argument must be
2573 NULL to silc_idlist_add_client function. If the client is not
2574 directly connected client then the `router' argument must
2575 bet set and the `connection' argument must be NULL to the
2576 silc_idlist_add_client function.
2578 * The funtion silc_server_packet_send_local_channel actually did
2579 not check whether the client was locally connected or not. It
2580 does that now. Fixed a bug related to LEAVE command.
2582 * Fixed Remove Channel User payload parsing bug in server's
2583 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2585 * The server's silc_server_save_channel_key now checks also the
2586 global ID list for the channel as it might not be in the local
2587 list. Fixed a bug related to LEAVE command.
2589 * Is this the end of the [<unknown>] buglet that has been lurking
2590 around for a long time? A little for loop fix in server's
2591 silc_server_command_whois_parse that is used by both IDENTIFY
2592 and WHOIS command. At least, this was a clear bug and a cause
2593 of one type of [<unknown>] buglet.
2595 * WHOIS and IDENTIFY commands call the function
2596 silc_server_command_[whois/identify]_check function even if
2597 we are not router server.
2599 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2601 * Added --with-gmp configuration option. If set the GMP
2602 is always compiled in the SILC source tree. If not set then
2603 it is checked whether the system has the GMP3 installed. If
2604 it has then the GMP won't be compiled (the system's headers
2605 and library is used), if it doesn't have it then the GMP is
2606 compiled in the SILC source tree.
2608 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2610 * Changed RSA private exponent generation to what PKCS #1
2611 suggests. We try to find the smallest possible d by doing
2612 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2613 not security fix but optimization.
2615 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * Added new config entry [Identity] to fork the server and run
2618 it as specific user and group. A patch from Bostik.
2620 * Imported Dotconf configuration library into lib/dotconf.
2621 This will be used to create the SILC configuration files later.
2622 It will appear in the distsribution after this commit.
2624 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2626 * A big code auditing weekend happening. Auditing code for
2627 obvious mistakes, bugs and errors. Also, removing any code
2630 Removed files for being obsolete:
2632 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2633 inline in the file lib/silcutil/silcbuffer.h)
2635 o lib/silcutil/silcbufutil.c (the header has inline versions)
2637 Changed code to fix possible error conditions:
2639 o The buffer formatting routines now check that the destination
2640 buffer really has enough space to add the data. This applies for
2641 both buffer formatting and unformatting
2642 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2643 unformatting was changed to accomodate following rules:
2644 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2645 sent to the function while XXX_*STRING will not allocate or copy
2646 the data into the buffer. Instead it sets the pointer from the
2647 buffer into the pointer sent as argument (XXX_*STRING used to
2648 require that the pointer must be allocated already). This change
2649 makes this whole thing a bit more consistent and more optimized
2650 (note that the data returned in the unformatting with XXX_*STRING
2651 must not be freed now). The routines return now -1 on error.
2653 o Tried to find all code that use buffer_format and buffer_unformat
2654 and added return value checking to prevent formatting and
2655 especially unformatting errors and possible subsequent fatal
2658 o Changed ske->x and ske->KEY to mallocated pointers in
2659 lib/silcske/silcske.h. Fixed possible data and memory leak.
2661 o Added return value checking to all *_parse* functions. Fixed
2662 many memory leaks as well.
2664 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2665 so that buffer overflows would not happen. All code now also
2666 checks the return value as it can fail.
2668 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2670 * Added reconnection support to server if the normal server looses
2671 its connection to the router (for example if router is rebooted).
2672 The server performs normal reconnection strategy implemented
2673 to the server. Affected file silcd/server.c.
2675 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2677 * Added new packet type SILC_PACKET_SET_MODE that is used to
2678 distribute the information about changed modes (for clients,
2679 channels and clients channel modes) to all routers in the
2680 network. Updated the protocol specification accordingly.
2682 Added functions into silcd/packet_send.c and
2683 silcd/packet_receive.c: silc_server_send_set_mode,
2684 silc_server_set_mode.
2686 Added new files silcmode.[ch] into lib/silccore that implements
2687 the encoding and decoding of Set Mode Payload. Added new type
2688 SilcSetModePayload. Moved the definitions of different modes
2689 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2691 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2693 * Oops, a little mistake in server's connection authentication
2694 protocol. The protocol is not ended with FAILURE but with
2695 SUCCESS if the authentication is Ok. :) Affected file is
2698 * Implemented NICK_CHANGE notify handling in server in the file
2699 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2700 the local clients on the channel. After the changing nickname
2701 in router environment snhould work and the [<unknown>] nickname
2702 should appear no more.
2704 The silc_server_replace_id function that receives the Replace ID
2705 payload now sends the NICK_CHANGE notify type also in the file
2706 silcd/packet_receive.c
2708 * Changed WHOIS and IDENTIFY command to support the maximum amount
2709 of arguments defined in protocol specs (3328 arguments). This
2710 fixed a bug that caused problems when there were more than three
2713 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2715 * Added extra parameter, command identifier, to the
2716 silc_client_send_command so that explicit command identifier
2719 Changed that ID list routines uses specific command identifier
2720 when sending WHOIS/IDENTIFY requests to the server so that they
2721 can be identified when the reply comes back.
2723 Affected files lib/silcclient/command.[ch],
2724 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2726 * Added `sender' argument to silc_server_packet_send_to_channel
2727 to indicaet the sender who originally sent the packet to us
2728 that we are now re-sending. Ignored if NULL. Affected file
2729 silcd/packet_send.[ch].
2731 * Added some server statistics support in silcd/server_internal.h
2732 SilcServerStatistics structure and around the server code. Also
2733 send some nice statistics information when client is connecting
2736 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2738 * Fixed channel ID decoding in server's JOIN command reply in
2739 silcd/command_reply.c
2741 * Fixed braodcasting of replace ID payload to not to send it if
2742 we are standalone server in silcd/packet_receive.c.
2744 * Fixed all channel message sending routines to not to send
2745 packets to clients that has router set, since they are routed
2746 separately in the same function earlier. Affects file
2747 silcd/packet_send.c and all channel packet sending functions.
2749 * In USERS reply, res_argv[i] are not allocated, the table
2750 is allocated. Thus changed that free the table, not its
2753 * In server's whois_check and identify_check if the client is
2754 locally connected do not send any WHOIS commands - they are not
2757 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2759 * Fixed some minor bugs in client when sending WHOIS command. The
2760 arguments was in wrong order.
2762 * Removed statis function add_to_channel from server in
2763 silcd/command.c that was previously used with the joining but
2766 * Tested USERS command in router environment successfully with two
2767 routers, two servers and two clients.
2769 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2771 * Reorganized the USERS command and command reply in client library
2772 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2773 When the command is given by user we register a pending command
2774 callback that will reprocess the command after the reply has been
2775 received from the server. When reprocessing the packet we then
2776 display the information. Thus, the USERS information is displayed
2777 now in the command callback instead of in the command reply
2778 callback. The processing of the command is same as previously
2779 when server has sent the command reply in the JOINing process.
2781 * Added to USERS command in silcd/command_reply.c to join the client,
2782 we didn't use to know about, to the channel after we've created
2783 a client entry for it. Also, for clienet we did know already still
2784 check whether it is on the channel or not and add it if not.
2786 * Removed silc_server_command_join_notify as the function and its
2789 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Changed the client's pending command handling to the same as the
2792 server's pending command handling. It is also now possible to
2793 execute command reply functions from other command reply
2794 function as the function callbacks for commands and command
2795 replies are one and same. The pending commands are not static
2796 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2797 in client connection context. Thus, pending commands are server
2798 connection specific as it is convenient.
2800 Changed the function silc_client_command_pending and
2801 silc_client_command_pending_del and added new function
2802 silc_client_command_pending_check. Removed the
2803 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2806 * Added cmd_ident, current command identifier, to the client
2807 connection context in lib/silcclient/client.h to keep track on
2808 command identifiers used in command sending. Client's command reply
2809 function handling now supports the mandatory command identifiers.
2811 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2812 funtions in client to fully support pending command callbacks.
2814 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2815 as one of the arguments to the application in the command reply
2818 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2819 before first releasing SILC but came back. Now it is removed again
2820 and should come back nomore. The FORWARDED flag was used only
2821 by the JOINing procedure by forwarding the command packet to router.
2822 Now, the JOINing procedure has been changed to more generic (due
2823 to various router environment issues) and FORWARDED is not needed
2824 anymore for anything. The protocol specification is yet to be
2827 Now, removed silc_server_packet_forward from server and the flag
2828 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2830 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2832 * Renamed NAMES command to USERS command. The NAMES was named that
2833 due to historical reasons. Now it is renamed. Also, rewrote
2834 parts of the USERS command. The nickname list is not sent anymore
2835 by the server. Only Client ID and mode lists are sent in the USERS
2836 command. Changed this also to the protocol specification.
2838 The client now resolves the names and stuff after it receives
2839 the USERS list from the server when joining to the channel.
2841 * WHOIS and IDENTIFY commands has been changed to support multiple
2842 Client ID's per command. One can now search for multiple users
2843 in the network by sending only one WHOIS or IDENTIFY command.
2844 Changed the code and the protocol specifications.
2846 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2847 uses silc_server_command_whois_parse to parse the request. */
2849 * If normal server, do not parse the WHOIS and IDENTIFY requests
2850 before sending it to the router. Saves some time.
2852 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Fixed JOIN command on client library. Wrong number of arguments
2855 used to crash the client.
2857 * Added silc_server_channel_has_global function to check whether
2858 channel has global users or not.
2860 * Added silc_server_channel_has_local function to check whether channel
2861 has locally connected clients on the channel.
2863 * The silc_server_remove_from_one_channel now checks whether the
2864 channel has global users or not after given client was removed from
2865 the channel. It also checks whether the channel has local clients
2866 on the channel anymore. If it does not have then the channel entry
2867 is removed as it is not needed anymore.
2869 * The silc_server_notify now checks on JOIN notify whether the joining
2870 client is one of locally connected or global. If it is global then
2871 the channel has now global users on the channel and that is marked
2872 to the channel entry. Also, it now saves the global client to
2873 global list who is joining and JOINs it to the channel. This is
2874 for normal server, that is.
2876 Changed silc_server_send_notify_on_channel,
2877 silc_server_packet_relay_to_channel and
2878 silc_server_packet_send_to_channel check if we are normal server
2879 and client has router set (ie. global client) do not send the
2880 message to that client, as it is already routed to our router.
2882 * Implemented LEAVE notify type handling in silc_server_notify
2885 * Tested LEAVE command in router environment successfully. Tested
2886 with two routers, two servers and two clients.
2890 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2892 * Implemented SIGNOFF notify type handling in silc_server_notify
2895 * silc_server_remove_id now removes the client entry from all channels
2896 it has joined and thusly sends SIGNOFF notify type.
2898 * Rewrote the NAMES list generation in server by removing two excess
2899 loops. The lists are created now inside one loop.
2901 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * silc_server_remove_channel_user checks now also global list
2904 for channel and client.
2906 * silc_server_new_channel_user checks now both local and global
2907 list for channel and client. Fixed a bug in client id decoding.
2908 Used to decode wrong buffer.
2910 * silc_server_channel_message checks now both local and global
2911 list for channel entry.
2913 * Tested channel joining (hence JOIN) in router environment
2914 successfully. Tested with two routers, two servers and two
2917 * Tested channel message sending in router environment successfully.
2919 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Added silc_server_save_channel_key into server.[ch] to save the
2922 received channel key in Channel Key payload processing. It is
2923 also used in JOIN command reply handling.
2925 Equivalent function silc_client_save_channel_key added into
2926 client.[ch] into client library.
2928 * Changed JOIN command reply to send information whether the channel
2929 was created or not (is existing already) and the channel key
2930 payload. Changed protocol specs accordingly.
2932 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2933 the request was sent by ID and not by nickname. Crashed on
2936 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2939 now correctly save the received data.
2941 * silc_server_free_sock_user_data now notifies routers in the
2942 network about entities leaving the network.
2944 At the same time implemented functions silc_server_remove_id
2945 and silc_server_send_remove_id to receive and send REMOVE_ID
2946 packets. The packet is used to notify routers in the network
2947 about leaving entities. The ID removed will become invalid in
2950 * Added function silc_idlist_del_server into server. Removes and
2951 free's server entry from ID list.
2953 * silc_server_private_message function now checks, if we are router,
2954 that the destination ID really is valid ID, naturally.
2956 * In router when NEW_ID packet is received (for new client) the
2957 hash of the Client ID is saved in the ID Cache but the
2958 client->nickname is set to NULL, instead of putting the hash
2961 IDENTIFY command now also checks that client->nickname must be
2962 valid. If it is not if will request the data from the server who
2963 owns the client. Added new function
2964 silc_server_command_identify_check.
2966 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2967 to set the command to already allocated Command Payload.
2969 * Tested private message sending in router environment with two
2970 routers, two servers and two clients. Fixed minor bugs and now
2973 * Fixed segfault from client's NAMES command. Used to crash if
2976 * Forwarded packets must not be routed even if it is not destined
2977 to the receiver. Changed server code comply with this.
2979 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2981 * Added `require_reverse_mapping' boolean value to ServerParams
2982 structure. If TRUE (not default) the server will require that
2983 the connecting host has fully qualified domain name.
2985 If the reverse mapping is not required and hostname could not be
2986 found the IP address is used as hostname.
2988 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2990 * Implemented version string checking to both client and server.
2991 The check is incomplete currently due to the abnormal version
2992 strings used in development version of SILC.
2994 * Changed all command functions in server to use the new
2997 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Changed char *data to unsigned char *data in ID Cache system to
3000 support binary data as ID Cache data. Changed code to support
3001 binary data in lib/silccore/idcache.c.
3003 * Renamed silc_server_packet_relay_command_reply to
3004 silc_server_command_reply as it is normal packet receiving
3005 function. Rewrote the function to accept command replys for
3006 servers and not only for clients.
3008 * Mark remote router always as registered server if we are connecting
3009 to it. Otherwise, commands sent by the router to us are ignored.
3011 * All ID List find routines now returns the ID Cache Entry pointer
3012 as well if requested.
3014 * WHOIS command works now in router environment, tested with two
3015 routers, two servers and two clients.
3017 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3018 in router environment (as it is almost equivalent to WHOIS) but
3019 hasn't been tested thoroughly. Added new functions:
3021 silc_server_command_identify_parse
3022 silc_server_command_identify_send_reply
3023 silc_server_command_identify_from_client
3024 silc_server_command_identify_from_server
3026 * Disabled route cache adding because adding two different ID's with
3027 same IP replaces the old cache entry thus giving wrong route.
3028 The entry->router->connection is always the fastest route anyway
3029 so route cache may not be needed. Of course, new routes maybe
3030 established after receiving the ID when the entry->router->connection
3031 might not be anymore the most optimal.
3033 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Add route cache for received ID for fast routing.
3037 * Added silc_server_packet_route to route received packet on router
3038 that is not destined to us.
3040 * Renamed silc_server_get_route to silc_server_route_get.
3042 * Added id_string and id_string_len fields into SilcServer to
3043 include encoded ServerID for fast comparing without excess
3044 encoding of the ID's.
3046 * Cleaned up WHOIS command on server side. Added following static
3049 silc_server_command_whois_parse
3050 silc_server_command_whois_check
3051 silc_server_command_whois_send_reply
3052 silc_server_command_whois_from_client
3053 silc_server_command_whois_from_server
3055 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3056 arguments in command replies. All command functions should be
3057 updated to use this macro.
3059 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Minor typo fixes on command reply handling on server.
3063 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Added silc_server_command_add_to_channel internal routine to add
3066 the client to the channel after router has created the channel and
3067 sent command reply to the server.
3069 * Added generic silc_server_send_command to send any command from
3072 * Use static buffer with ID rendering instead of duplicating data.
3074 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3076 * Fixed a channel user mode bug when joining to a channel server gave
3077 everybody channel founder rights, oops.
3079 * We mark ourselves as the router of the incoming server connection
3080 if we are router ourselves. This way we can check in some packet
3081 sending functions whether it is locally connected server. For
3082 incoming router connections we put NULL.
3084 * For router sending packets locally means now always sending the
3085 packet cell wide; to local clients and local servers. For normal
3086 server sending packet locally means sending it to only local
3089 * Fixed the JOIN command to really work in router environment. If the
3090 channel is created it is always created by the router. Router is
3091 also responsible of making the initial joining to the channel,
3092 sending JOIN notify to the sending server and distributing
3093 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3094 does not exist server doesn't do anything else but forward the
3095 command to the router which performs everything.
3097 * Added silc_server_send_channel_key function to send the Channel Key
3100 * Added silc_server_create_channel_key to create new channel key. The
3101 channel key is now re-generated everytime someone joins or leaves
3102 a channel, as protocol dictates. Note: channel->key_len is the
3105 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3108 packet_receive.[ch] to separate packet sending and receiving
3109 routines. The server.[ch] now includes everything else including
3110 actual packet processing (writing and reading data) and other
3113 Renamed silc_server_private_message_send_internal to
3114 silc_server_send_private_message. The routine is still though
3115 used only to relay private messages as server does not send
3116 private messages itself.
3118 Renamed silc_server_new_channel to silc_server_create_new_channel
3119 and added new function sicl_server_new_channel that handles the
3120 incoming New Channel packet. Added also new sending function
3121 silc_server_send_new_channel to send New Channel Payload.
3123 * Added new function silc_server_notify to process incoming notify
3124 packet to the server/router. Server may then relay the notify
3125 to clients if needed.
3127 * Added new function silc_server_new_channel_user to process incoming
3128 New Channel User packet. Router will redistribute the packet and
3129 send JOIN notify to its local clients and locally connected servers
3130 if needed. Normal server will send JOIN notify to its local client
3131 on same channel when received this packet. Added also corresponding
3132 sending function silc_server_send_new_channel_user to sent the
3135 * Added boolean route argument to send_notif_to_channel and
3136 packet_send_to_channel functions to attempt to route the packet
3137 if it is TRUE and send only locally if it is FALSE.
3139 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3141 * silc_server_replace_id now broadcasts the received replace ID
3142 packet if it is not broadcast packet already. The router must
3143 broadcast to inform other routers about changed ID.
3145 * Added backpointer to server's router into SilcServer context in
3146 silcd/server_internal.h.
3148 * Fixed silc_server_packet_broadcast to send correct broadcast
3151 * The channel key is now distributed to the local client as soon
3152 as it is received from the router (in router environment) so that
3153 no other packet may be sent for the channel until client has
3156 * silc_server_remove_channel_user now broadcasts the received
3157 Remove Channel User packet if it is not broadcast packet already.
3158 The router must broadcast to inform other routers about removed
3161 * Added users field into SilcPacketContext that is a reference count
3162 of the context. One can increase the reference count by calling
3163 silc_packet_context_dup which is now changed to just increase the
3164 reference count instead of duplicating the data. The reference
3165 count is decresed by calling silc_packet_context_free that will
3166 free the data after the reference count hits zero.
3168 For now on the packet context and everything allocated into it
3169 (including the raw packet from network) must be freed by calling
3170 the new silc_packet_context_free function. Added also new function
3171 silc_packet_context_alloc that must be used now to allocate the
3172 context. This also means that if a routine is asynchronous from
3173 silc_[client/server]_packet_parse_type the packet context must
3174 be duplicated by calling silc_packet_context_dup. Otherwise it
3175 gets free'd after silc_[client/server]_packet_parse_type returns.
3176 Also, one must remember that if packet is duplicated then its
3177 reference count must be decresed by calling the free function as
3178 many times as it was duplicated.
3180 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3181 from both client and server.
3183 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3185 * Made joining to a channel working in router environment.
3187 * Cleaned up JOIN command on server side and create function
3188 silc_server_command_join_channel internal routine to make the
3191 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3193 * Changed silc_command_pending list to SilcDList. Also, added
3194 `ident' field to SilcServerCommandPending structure to identify
3195 the reply and to call correct callback.
3197 Added silc_server_command_pending_check function to replace the
3198 corresnponding macro. The silc_command_pending list is not
3201 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3202 to set identifier to previously allocated Command Payload. It
3203 is used to set identifier for command when resending Command
3206 * Added silc_command_payload_encode_payload to encode Command
3207 Payload buffer from SilcCommandPayload structure.
3209 * Added silc_argument_payload_encode_payload to encode Argument
3210 payload buffer from SilcArgumentPayload structure.
3212 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Changed WHOIS command to support router connection on server side.
3215 The whois request is always sent to router unless the server is
3216 standalone server. After server has received the reply from the
3217 router will it send the reply to the client.
3219 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3220 broadcast received broadcast packet. The function is used only
3221 by router. The broadcast packet is always sent to the router's
3224 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3225 render given ID to printable string, for log files for example.
3227 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3229 * Made basic router to router connections working. At least they
3230 can now connect to each other but nothing really works the way
3231 they are supposed - yet.
3233 * Added new initiator token to RouterConnection configuration
3234 file in silcd/serverconfig.[ch]. It is used to tell whether we
3235 are the initiator to the remote router or whether we'll expect
3236 the other end to connect.
3238 * Moved registering of listener task to silc_server_init, hence
3239 the server starts listenning as soon as it is run, even if it
3240 does not have connections to other routers. Let's see how well
3243 * Changed default connection retry timeouts for more suitable in
3246 * Removed cipher and such arguments from silc_idlist_add_client
3247 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3248 Added new function silc_idlist_add_data to add the keys and stuff
3251 * Added SilcIDListData structure and added it to SilcClientEntry
3252 and SilcServerEntry as their first field in the structure. This
3253 way we can explicitly cast the ID entries to the SilcIDListData
3254 structure and get common data for the entries. In past, we had
3255 to first check what type of connection it is and then cast it to
3256 correct ID entry type. Now, we can directly cast the opaque
3257 pointer to the SilcIDListData (no matter what ID entry it actually
3258 is) and get the data needed.
3260 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3263 in some circumstances even if threre were timeout tasks, though not
3264 IO tasks, but tasks anyway. Now fixed.
3266 * Defined SilcServerConnection structure to hold connection specific
3267 stuff about directly connected servers and routers. The definition
3268 is currently in silcd/server_internal.h. I thought about having
3269 a bit more important role fro this struct but for now it is used
3270 only when connecting to other server (or router actually).
3272 * Added connecting retry support in server when connecting to
3273 router(s). The retry feature implement exponential backoff
3274 algorithm. Also, added SilcServerParams structure to hold default
3275 parameters for server. For now, it include these retry settings
3276 and are hard coded. After server is moded to be as Silc Server
3277 Library this structure will be more important.
3279 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Changed client librarys channel->clients table to SilcList and
3282 changed code accordingly.
3284 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3286 * Changed client's channel table to SilcList and changed code
3287 accordingly. Also changed SilcChannelClientEntry to include back-
3288 pointer to the channel so that client entry can use that structure
3289 as list as well and we have fast cross-reference to the channel.
3290 This change dramatically decreased the complexity of channel
3291 handling with client entry and vice versa (removed one extra
3292 loop when searching for channel entry from many functions).
3294 * Changed server->sim from table to SilcDList and changed code
3297 * NAMES command can now be used from user interface. It will show
3298 the user list on the channel, neatly.
3300 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3301 Code now saves realname of the user if it becomes available.
3303 * Renamed configure.in to configure.in.pre and made ./prepare
3304 script to automatically add correct version string to
3305 configure.in which it creates from configure.in.pre.
3307 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * NAMES command reply now shows users mode with the nickname when
3312 * Moved silc_client_ch[u]mode[_char] functions from
3313 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3314 place sucks, they are utility functions and should be in some
3317 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3319 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3322 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Added TRQ (efficient deque and list library) into lib/trq. This is
3327 a very good list library that is currently used in the SILC. Defined
3328 SilcList API over the library because I didn't like the API very
3329 much. See lib/trq/silclist.h for the API and examples of how to
3330 use the API. Fixed various places in the code to use the new
3331 SilcList API. The SilcList is meant for lists that has a structure
3332 already defined as a list. It is not suitable to add just some
3333 context to the list (in TRQ, the context is the list actually).
3335 So, I defined SilcDList that can be used for the purpose where
3336 predefined list structure does not exit. This can be used as
3337 such list. Now some context just can be added to the SilcDList.
3338 Currently this list is not used in the SILC just yet, though there
3339 are a lot places where this can replace dynamically allocated
3340 tables and I will fix these places, later, to use SilcDList.
3341 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3342 and use TRQ internally).
3344 Also fixed some annoying warning messages that the original TRQ
3345 code generated. Also minor changes to TRQ's Makefile.in.
3347 * Added support for querying by Client ID to both WHOIS and
3348 IDENTIFY commands into server, as required by the protocol.
3350 * Removed method function pointers from SilcBuffer structure. They
3351 weren't used to anything and just increased the context size for
3352 no good reason. This change also made silc_buffer_alloc and
3353 silc_buffer_free functions inline functions.
3355 * Disabled command flooding detection support until it's fixed so
3356 that it accepts commands in but does not execute them more than once
3359 * Added silc_net_localhost(), to return local hostname, into
3360 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3361 that must be initialized before calling silc_client_init.
3363 * Added new function: silc_server_send_notify_on_channels to send
3364 notify messages to all channels client has joined. It is assured
3365 that the message is sent only once per client.
3367 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3368 lib/silcutil/silcutil.[ch] as silc_format function. The new
3369 function is generic and is used by server as well, not only by
3370 the logging routines.
3372 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3373 the provided version string was not acceptable. Added new function:
3374 silc_ske_check_version into lib/silcske/silcske.h. The function
3375 must be implemented by the application (client or server) and it
3376 does not reside in the SKE library. The function checks the version
3377 string remote end sent.
3379 * Added back pointers (to opaque context and to SilcSocketConnection)
3380 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3382 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3383 duplicate packet context structure.
3385 * Changed `notify' client operation to send same arguments as client
3386 receives from server except for ID's. ID's are mapped to correct
3387 ID entry and that is returned. Also, if channel entry is not sent
3388 by server but the notify is for channel the channel entry is sent
3389 to application (otherwise application doesn't know that it is for
3390 channel (library gets it from packet's Destination ID)).
3392 * Added silc_client_remove_from_channels into client library to
3393 remove a client from all channels it has joined to. Used when
3394 received SIGNOFF notify from server. Added also new function
3395 silc_client_replace_from_channels to replace old ID entry with
3396 new ID entry on all channels. Used when received NICK_CHANGE
3399 * Fixed ID Cache list handling in silc_idlist_get_client in
3400 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3401 to get (or query) client by ID.
3403 * Updated TODO list.
3405 * Added connection authentication status message defined by the
3406 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3407 support for these into the code in client and server side.
3409 * Added generic function silc_client_send_command to send any command
3410 with variable argument list. Application should use this function
3411 to send commands if the command functions provided by the library
3412 does not suite for the application's user interface needs.
3414 * Added new `failure' client operation. Application is notified about
3415 received failure packet if client is executing a protocol. In this
3416 case the protocol's execution has failed.
3418 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3419 is required by the protocol.
3421 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3422 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3425 * Added status flag to SilcSKE object to indicate realtime status
3426 of the SKE protocol.
3428 * Application receives now exactly same command reply arguments as
3429 the library receives from server. However, if ID is received the
3430 corresponding ID entry is returned to the application (eg. Client
3431 ID is mapped to correct SilcClientEntry entry and that is returned).
3432 Changed command_reply client operation due to this change.
3434 * Changed all ID's in commands and in command replys as ID Payloads.
3435 Change affected both client and server side codes.
3437 All ID's sent in SILC network (with execption of ID's in SILC
3438 Packet header) are sent in ID Payload to support variable length
3441 * Server now notifies nick changes and notifies all clients on
3442 the channels about the new nickname (about the new Client ID,
3445 * Implemented CMODE command to change channel modes. Supports all
3446 channel modes defined by the protocol specs except ban and invite
3447 lists. (Also, private channel key mode is supported but support for
3448 setting private channel key in client is missing, thus, this mode
3449 has no effect on client side (except that server requires that the
3450 client uses private channel key and normal channel traffic does not
3453 Also, invite mode works per se, but INVITE command does not work
3454 yet correctly, so you can set channel as invite only channel but
3455 inviting clients to the channel does not work (it is yet to be
3456 thought what's the best way to do it).
3458 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3459 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3460 Implemented CUMODE command to change user's mode on the channel.
3461 Supports all modes defined by the protocol specs.
3463 * Added NAMES command reply to return users modes on the channel.
3465 * Removed unnecessary and slow ciphers from lib/silccrypt.
3467 * Set SO_KEEPALIVE option to connection sockets by default.
3469 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3471 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3472 redefined the Notify Payload into protocol specs.
3474 * Added silc_id_payload_parse_id to get ID directly from raw
3477 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3480 accept searching by Client ID as well.
3482 * Added support for LEAVE and SIGNOFF notify types in client library.
3484 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3485 to parse ID Payload from raw data.
3487 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Added flags parameter into silc_ske_assemble_security_properties
3490 function in lib/silcske/silcske.[ch].
3492 * Changed notify client operation to fit better for notify messages
3493 sent by server. The notify payload received from server is now
3494 passed to the application (after parsing it to SilcNotifyPayload).
3495 It is application's responsibility to retrieve the arguments
3496 from the payload and show the message the way it wants. The message
3497 sent by server is implementation specific.
3499 * Changed public keys to comply with the protocol specification.
3500 Old public keys are not supported anymore and are not compatible.
3502 * Removed nickname from Channel Payload as the latest draft removed
3503 it. The client must resolve the nickname from the NAMES command
3504 reply received when it joined the channel.
3506 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3508 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Fixed some errors in protocol specification drafts.
3512 * Created lib/silccore/silcnotify.c to implement Notify Payload
3513 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3514 generic payloads described by protocol specifications. The file
3515 includes implementations for ID Payload and Argument Payload.
3517 * Changed Command Payload implementation to use the new Argument
3518 Payload. Changed command_xxxx_payload to command_payload_xxxx
3519 to comply with SILC coding conventions.
3521 * Added suppport for Argument Payload handling in Notify Payload
3522 implementation as protocol requires it. Added the new support
3523 into server and client lib as well.
3525 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3527 * Added support for multiple nicknames on same channel. [n] is
3528 added locally to the nickname if there are more than one same
3529 nicknames on the channel.
3531 * Server now sends all nicknames that matched WHOIS request.
3532 Client also shows the list received from server.
3534 * Added TOPIC command to client side. User can now set and show
3535 current topic on channel.
3537 * Added MOTD command to client and server. Also, server sends the
3538 motd when client connects to the server.
3540 * Changed version strings to comply ISO 8601.
3542 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3544 * Fixed protocol error handling in client library. It should now
3545 cope even if the SKE fails for some reason.
3547 * Made new protocol specification drafts for submitting to IETF.
3549 * Implemented TOPIC command to server in silcd/command.c.
3551 * Added two new notify types into lib/silccore/silcnotify.h:
3552 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3553 notify nickname change and topic setting/change on a channel.
3555 * API change of command_reply operation in client library. The
3556 application gets now the status type received from server as well.
3558 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3560 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3562 * Cras fixed and optimized the packet handling even further and
3563 it should work now. Minor change to the prototype of function
3564 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3566 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3568 * Added new function into lib/silcutil/silcschedule.[ch]:
3569 silc_schedule_with_fd to select() a specified fd. The function
3570 returns after timeout expires or data arrives or goes. The
3571 function is used by packet routines to wait that all data is
3572 received from network.
3574 * Fixed data reading from network in lib/silccore/silcpacket.c.
3575 The code now assures that all data is read from the fd and then
3576 continues packet processing. This was a bug fix since the code
3577 used to drop some data in some circumstances.
3579 * Added new function into lib/silcclient/client.[ch]:
3580 silc_client_start_key_exchange to start key exchange after
3581 connection has been established to server. The code internally
3582 now uses this funtion but its main purpose was to provide it
3583 for applications that perform their own connecting. After
3584 application has created a connection it merely calls this
3585 function to start the key exchange between client and server.
3586 The library takes care of everything else after that.
3588 Updated also lib/silcclient/README to explain the usage of
3591 * Do not send to application information that connection has
3592 been established. Application gets notified it by connect
3595 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Applied cras's patch to add silc_schedule_one function. The
3598 function runs scheduler once and returns.
3600 * Fixed the scheduler after cras messed it up. The timeout
3601 handling works now as it's supposed to work.
3603 * Added into lib/silccore/ silcnotify.h to include notify
3604 message types support. Changed silc_server_send_notify*
3605 functions, in server.[ch], to support those new notify types.
3606 Added the support for the notify types into client library,
3607 as well. Added new notify client operation into ops.h in
3610 * Changed silc_server_packet_send_to_channel to send normal
3611 packets instead of just channel message packets. The function
3612 is now used to send the notify packets to channels. It is not
3613 used to send channel message packets anymore, as server never
3616 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3617 va_arg()s as it seems to require it nowadays. I guess, if SILC
3618 is compiled with older va_arg() the new code should work anyway.
3620 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Splitted core library. Core library (lib/silccore) includes
3623 now only SILC protocol specific core (and common) components.
3624 Created new utility library (lib/silcutil) that includes more
3625 generic purpose stuff. The stuff for util library was taken
3626 from the old core library. This was minor and easy split.
3628 * Created SILC Client Library (lib/silcclient) that includes
3629 implementation of the SILC client without user interface. This
3630 was major move from silc/ directory. The code has been changed
3631 so that it is transparent towards the user interface. The
3632 silc/ directory includes now the same user interface as before
3633 and it uses the new client library. Read lib/silcclient/README.
3634 Basicly, the client library performs everything else related
3635 to SILC except user interface handling. Also, configuration
3636 files are considered to be part of user interface and library
3637 does not handle them.
3639 This change also changed a lot of structures, function naming etc.
3640 Most important change was that SilcClientWindow object was
3641 renamed to SilcClientConnection in the client library. Created
3642 also new file lib/silcclient/ops.h. Also added new files
3643 silc/local_command.[ch] and silc/client_ops.[ch].
3645 All these changes were made to make it easier for user interface
3646 designers to create what ever user interface for the SILC client
3649 It is also expected that the server will be moved to lib
3650 directory as well and SILC Server Library will be created;
3651 sometimes in the future.
3653 * Removed Local commands from lib/silccore/silccommand.h as
3654 they are application specific and new client library does not
3655 handle any of those anymore.
3657 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3658 old client implementation in silc/.
3660 * Added support for callback functions in SILC_LOG_* macros.
3661 Application can now set its own callbacks that will be called
3662 instead of using the default functions that will always print
3663 the debug messages to stderr (or stdout). Also, debugging can
3664 now be disabled by setting silc_debug to FALSE and re-enabled by
3665 setting it to TRUE. Note, that logging will still work even
3666 if debugging is disabled.
3668 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3669 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3670 silc_log_reset_debug_callbacks.
3672 * To enable debugging in silc client one must give now -d
3673 option on command line.
3675 * Changed silc_schedule_init to automatically allocate task queues
3676 if they are not allocated before calling it.
3678 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Added GMP 3.1 into math library.
3682 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3685 a channel in SILC network. The packet is used by servers and
3686 routers to notify other routers that user has left a channel.
3687 This little feature was missing until now. Added the feature
3688 to protocol specification as well.
3690 Added functions: silc_server_send_remove_channel_user and
3691 silc_server_remove_channel_user into server.[ch].
3693 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3694 lib/silccore/silcpacket.h. However, they are not implemented
3697 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3699 * Fixed joining to a channel and sending channel messages
3700 between server and router. The channel message sending should
3701 now work inside a cell.
3703 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Fixed the private message sending between server and router.
3706 The private message sending should now work inside a cell.
3708 * Added silc_server_replace_id into server.[ch] to replace
3709 existing ID in the SILC network.
3711 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3712 and silc_idlist_replace_server_id into idlist.[ch] in server.
3714 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Fixed the server to server connections. Server can again now
3717 connect to router. Router to router connections probably does
3720 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Added dynamic protocol registering support. Now protocols can
3723 registered and unregistered on the fly. Patch by cras.
3725 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Added lib/contrib directory to hold routines that some platforms
3728 don't have but are needed by SILC.
3730 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3731 into lin/contrib to provide getopt() and getopt_long() for
3732 those who don't have it.
3734 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3736 * Added AWAY command to client. When away message is set and
3737 client receives a private message packet the client automatically
3738 replies to the sender with the away message.
3740 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3741 bug seemed to be the cause of recent problems when compiling
3744 * Added version detection support to SKE protocol specification
3745 and added the new changes to the SKE implementation as well.
3746 There were other minor changes in the SKE protocol as well.
3748 Many changes in lib/silcske/silcske.[ch] and in
3749 lib/silcske/payload.[ch].
3751 * Added ^U functionality, clear input line. Patch from cras.
3753 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Mainly small bugfixes on core library. Fixed some debugging
3756 logging and buffer overflow in silclog.c.
3758 * Updated config.sub and config.guess on the distribution tree.
3760 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Added command lagging support in server. Client may execute
3763 commands now only once in two seconds.
3765 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3767 * Optimized packet reception. MAC computation and checking is now
3768 also more optimized. A lot previously duplicated code is now
3769 used as generic by both client and server.
3771 * Fixed key pair generation in clientutil.c
3773 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Added into lib/silccore/silcbufutil.[ch] new function;
3776 silc_buffer_realloc.
3778 * Moved generic packet sending/encryption functions to
3779 lib/silccore/silcpacket.[ch] from client and server. Some
3780 rewriting of the functions.
3782 * Moved all generic packet reception/decryption functions to
3783 lib/silccore/silcpacket.[ch] from client and server. The
3784 packet processing is now much cleaner in both client and server.
3785 These were major changes in both client and server.
3787 * Created many common functions in server to do packet sending.
3788 Previously code were duplicated a lot, this has been removed
3791 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Rewrote major parts of the ID cache system. Don't know
3794 whether it is better now or not but at least the API is more
3797 * Major rewrite on ID cache stuff on client because of the ID
3798 cache API changes. Added idlist.c to client.
3800 * Also major rewrite on ID cache stuff on server as well.
3801 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3802 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3803 in hand, instead they are all put into the ID cache system now.
3804 All server_idlist_* routines uses ID cache now instead of
3805 traversing its own lists (those lists does not exist anymore).
3806 SilcIDList though still exists. Also, SilcXXXEntry's are
3809 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Finally made the SKE implementation compliant to the protocol
3812 specification. All mp integers are now binary encoded as
3813 opposed being HEX encoded.
3815 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3818 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3819 functions: silc_[encode/decode]_pem. Also added function
3820 silc_encode_pem_file to PEM encode with newlines ('\n') for
3823 * SILC public keys are now encoded either PEM or binary. Same
3824 option is for private keys as well. By default private keys
3825 are binary encoded and public keys PEM encoded. Silly HEX
3826 encoding were removed.
3828 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3829 function to create fingerprints.
3831 * Fixed a bug in SHA1; does not change the original data anymore.
3833 * Partly implemented INFO command on client and server side.
3834 Fixed CLEAR command. Changes to SERVER command; show current
3835 server(s) when giving command without arguments. Added
3836 VERSION command to client.
3838 * Added check to server that unregistered connections cannot
3839 execute commands (unless it is specificly allowed).
3841 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Fixed screen refresh.
3845 * Fixed channel joining bug from client. On some circumstances
3846 client tried to join to a channel it had already joined.
3848 * Added public key verification process into client's protocol.c.
3849 The client now verifies the public key from user and saves
3850 it into ~./silc/serverkeys/ directory.
3852 Added into: clientutil.[ch]: silc_client_verify_server_key.
3854 * Changed SKE protocol's silc_ske_initiator_finish function
3855 to accept callback function that verifies the received public
3856 key. Removed old silc_ske_verify_public_key function.
3858 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3861 silc_pkcs_private_key[_data]_set.
3863 * Made the password and public authentication more cleaner in
3864 server's protocol.c.
3866 * Removed historic and obsolete protocol `channel_auth' from
3867 both client and server.
3869 * Removed wrong way of sending command status messages from
3870 server to client in server's command.c. The old way violated
3871 protocol specification.
3873 Changes to silccore/silccommand.[ch]: removed
3874 silc_command_encode_status_payload -> not needed anymore,
3875 changed silc_command_encode_payload_va to accept extra
3876 argument on variable argument list. The argument type must
3877 now be provided to the function. Also, added new function:
3878 silc_command_encode_reply_payload_va which is same as
3879 normal command_encode_payload_va except command status type
3880 is provided as extra argument.
3882 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Added ~./silc directory handling. The directory includes the
3885 public and private keys for the client.
3887 Added silc_client_check_silc_dir, silc_client_create_identifier
3888 and silc_client_load_keys.
3890 * Implemented SILC protocol compliant public key. Added public
3891 and private key saving to and loading from files.
3893 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3894 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3895 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3896 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,

3904 * Added silc_server_get_route (route.[ch]) to get connection
3905 data for the fastest route for given ID.
3907 * Implemented INVITE command on client and server. The command
3908 were re-defined in the SILC Protocol Specification and the
3909 implementation now complies with the specification.
3911 * Implemented PING command on client and server.
3913 * Implemented NAMES command on client and server. The server side
3914 supports currently only normal server not router server yet.

3921 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3922 again. This change was made to the protocol as well. Server
3923 should not violate the protocol specification anymore.

3927 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3928 was tested. SOCKS4 was not but should work anyway.
