1 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed the GETKEY command in the server to check also the
4 global list. Otherwise the GETKEY would not work correctly
5 in normal SILC server. Affected file silcd/command.c.
7 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
9 * Fixed GETKEY crash, it crashed if the command did not succseed.
11 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
13 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
14 is now real and not just an macro interface to GMP.
16 Removed the entire GMP from the source tree and imported new
17 NSS MPI library instead. Reason for removing GMP is that it is
18 extremely large and compiles extremely slow. The NSS MPI
19 is only a few files and compiles in less than 10 seconds.
20 The speed is also about the same as GMP. The MPI is imported
23 If the system has GMP installed we will still use the GMP.
24 If it is not then the NSS MPI will be compiled.
26 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
28 * Merged a long nickname (127 characters long) crash bugfix from
29 Irssi CVS tree. Affected file irssi/src/core/misc.c.
31 * Merged a freed memory reference bugfix from Irssi CVS tree.
32 Affected file irssi/src/core/commands.c.
34 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
36 * Added the server's public key sving and verification to the
37 server when performing the SKE. This was missing and the
38 remote server's (or router's) public key was accepted without
39 checking whether we have it previously or trust it at all.
40 Affected file silcd/protocol.c.
42 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
44 * Check in the silc_server_timeout_remote if protocol is active
45 and make sure that the protocol's final callback is called so
46 that all memory if freed. Affected file silcd/server.c.
48 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
50 * silc_server_whois_send_reply crashed the server if the nickname
51 was 127 characters long. Affected file silcd/command.c.
53 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
55 * Added sanity check to the silc_server_new_client. If the hostname
56 is provided inside username then check that the provided hostname
57 really is the same as the resolved one. If the hostname was not
58 resolved then check it from the public key. Affected file is
59 silcd/packet_receive.c.
61 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
62 if the server disconnected us and the connection is not valid
63 anymore. Affected file irssi/src/silc/core/silc-channels.c.
65 * Moved the silc_client_[chmode|chumode|chumode_char] away from
66 the library to the lib/silcutil/silcutil.[ch].
68 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
70 * Close log file after open. Affected file
71 lib/silcutil/silclog.c.
73 * Check whether sock == NULL in silc_client_send_packet and return
74 if it is. Affected file lib/silcclient/silcclient.c.
76 * Check rec->entry == NULL in the Irssi SILC Client before
77 sending the channel message. Affecte file is
78 irssi/src/silc/core/silc-servers.c.
80 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
82 * Merged a splitted window bugfix from Irssi CVS tree. The
83 affected file is irssi/src/fe-text/textbuffer-view.c.
85 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
86 It did not print nickname.
88 * Improved the distributions system a bit.
90 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
92 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
93 irssi/src/fe-text/gui-window.c.
95 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
96 to in-active server. The affected file is
97 irssi/src/silc/core/client_ops.c.
99 * Resolve the client in USERS command reply if the entry does
100 not have username resolved. The affected file is
101 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
102 command to WHOIS command to really resolve stuff. The USERS
103 is not used any more in any critical section so WHOIS can
104 be used even though it might be slower than IDENTIFY.
106 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
109 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Changed the protocol API a bit more consistent in the
112 lib/silccore/silcprotocol.[ch].
114 * Changed the following headers to ROBODoc format:
116 lib/silccore/silcpayload.h
117 lib/silccore/silcprotocol.h
118 lib/silccore/silcsockconn.h
120 All core library headers are now formatted.
122 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
124 * Fixed a bug in Irssi SILC client; do not show that you are
125 server/router operator if you really are not. Affected file is
126 irssi/src/silc/core/client_ops.c.
128 * Renamed silc_command_free_payload to silc_command_payload_free.
129 Affected file lib/silccore/silccommand.h
131 * Added silcmath.h to include the prototoypes of various routines
132 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
135 * Changed the following headers to ROBODoc format:
137 lib/silccore/silcchannel.h
138 lib/silccore/silccommand.h
139 lib/silccore/silcid.h
140 lib/silccore/silcidcache.h
141 lib/silccore/silcmode.h
142 lib/silccore/silcnotify.h
143 lib/silccore/silcpacket.h
144 lib/silcmath/silcmath.h
146 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Added checking to the server code not to start the server if
149 ciphers and stuff are not configured properly. Affected files
150 silcd/serverconfig.[h] and silcd/server.c.
152 * Changed the layout of the header files of the public interfaces
153 in the SILC libraries. The new layout supports ROBODoc
154 documentation tool (and some others) so that it is easy to create
155 a library reference manual. All the other headers and source
156 code must still follow the CodingStyle document. Also source
157 code must not include these ROBODoc stuffs, only the headers.
158 Furthermore, all public interface headers must now be named
159 by using `silc' prefix, example: silcapi.h, silccipher.h.
160 Some files were renamed due to this. All the other headers
161 must not be used as public interfaces. I will update the
162 CodingStyle document later. Changed following headers, so far:
164 lib/silcclient/silcapi.h
165 lib/silccore/silcauth.h
166 lib/silccore/silcprivate.h
167 lib/silccrypt/silcdh.h
169 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
173 * Removed silc_client_packet_send_flush from the client library
174 as it is not needed. Affected file lib/silcclient/client.[ch].
176 * Added printing of message of unresolved authentication method
177 to the Irssi SILC client. Added it to the module formats.
178 Removed the same message from the client library.
180 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
182 * Added new distribution feature, DISTLABEL. Every distribution
183 can define own preprocessor label that can be used in the
184 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
185 file distributions, acconfig.h.pre and prepare.
187 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
189 * Added Makefile.defines_int to include the actual definitions
190 for Makefile.defines.in. Tested the new distribution system,
191 created distributions and tested installation.
193 * Added AWAY message printing to the Irssi SILC client. Added
194 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
196 * Added SCONNECT command to call the SILC's CONNECT command.
197 Cannot use CONNECT directly since Irssi uses that internally.
198 Affected file irssi/src/silc/core/silc-servers.c.
200 Added ACTION local command. It is same as ME command but takes
201 the channel as mandatory argument.
203 Rewrote some of the Irssi's help files to suite for SILC
206 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Added Makefile.defines[.in] that should for now on be included
209 in all Makefile.am file in the source tree. That file includes
210 all common compilation definitions for SILC source tree.
212 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
214 * Minor changes to the ./prepare script to change the package
215 name according the distribution name to the configure.in.
217 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
219 * Created new distribution system. Added file `distributions'
220 that defines all the distributions that can be created out of
221 the SILC source tree. The ./prepare script now reads that
222 file to determine how to prepare the distributions. The
223 first argument to the ./prepare is the name of the distribution
224 and second is the version of the distribution. If given
225 without arguments it creates the default (toolkit) distribution
226 with the default version (defined in ./prepare).
228 All Makefile.am files that are subject to the distributions
229 are now named as Makefile.am.pre. These are ./Makefile.am
230 and lib/Makefile.am. Others may be changed later.
232 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
234 * Added invite list, ban list, some key management and connection
235 error message printing to module formats in the Irssi SILC client.
237 * Added new silc_client_set_away_message to set the away message
238 that is back to the person who sent private message. The
239 affected file lib/silcclient/silcapi.h and the
240 lib/silcclient/client_prvmsg.c.
242 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
244 * Fixed the private message sending in the Irssi SILC client,
245 added local command KEY to the Irssi SILC client.
247 Added key management and key agreement message formats to the
248 irssi/src/fe-common/silc/module-formats.[ch].
250 Added USERS (alias WHO) printing, server/router operator
251 indication and LIST command printing to the module formats.
253 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
255 * Fixed channel joining notify handling, cumode notify handling
256 from Irssi SILC client.
258 * Added SILC specific module-formats to the Irssi SILC client so
259 that SILC specific message hilighting, colors etc is possible.
260 Affected file irssi/src/fe-common/silc/module-formats.[ch].
262 Added channel mode, channel user mode, actions, notices,
263 whois and whowas printing to the the module-formats.c.
265 * Fixed a bug in channel deletion in the server. The channel
266 is not left to the cache even if the channel founder auth mode
267 is set when there are no users anymore on the channel. Affected
270 * The silc_net_localhost now resolves the entire hostname including
271 the domain name. Affected file lib/silcutil/silcnet.c.
273 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
275 * Changed the ask_passphrase client operation to be ascynchronous.
276 It has now a completion callback and a context that the
277 application must call after it has got the passphrase from
278 the user. Affected files lib/silcclient/silcapi.h,
279 lib/silcclient/protocol.c, lib/silcclient/command.c and
282 Added SilcAskPassphrase callback that the application calls
283 to deliver the passphrase to the library.
285 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
286 The public key verification and especially a certificate
287 verification is asynchronous procedure.
289 Added new SILC_SKE_STATUS_PENDING status to indicate the
290 request is pending and a callback will be called to finalize
293 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
294 indicate that remote end did not send its public key (or
295 certificate), even though we require it. Added check for this
296 condition in the SKE. This was a security bug, now fixed.
298 Defined new SilcSKEVerifyCbCompletion callback that is called
299 when the verification process is completed.
301 The affected files lib/silcske/silcske_status.h and
302 lib/silcske/silcske.[ch].
304 * Changed the verify_public_key client operation to be async
305 as well. Defined SilcVerifyPublicKey callback that is used to
306 indicate the success of the public key verification process.
308 Changed the server and client to use the new async client
311 * Changed the Irssi SILC client's internal scheduler to be called
312 twice as many times as it used to be. As a result the client
313 should be a bit faster now. Affected file is
314 irssi/src/silc/core/silc-core.c.
316 * Added support to Irssi SILC client of asynchronous public key
317 verification and passphrase inquiry. Affected file is
318 irssi/src/silc/core/silc-core.c.
320 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
322 * Do not say "You have left channel %s" in client library.
323 Moved it to the application. Affected files are
324 lib/silcclient/command.c and silc/client_ops.c.
326 * Fixed silc_client_get_clients. Command context was not
327 duplicated and was freed memory in the callback. Affected
328 file lib/silcclient/idlist.c.
330 * Do not say "you are now talking..." on JOIN command in the
331 client library. The appliation must handle it.
333 * Do not say ".. changed topic to" in command reply in the
334 client libary. The application must handle it.
336 * Fixed TOPIC command sending in the client library.
338 * Fixed a memory leak in silc_client_command_free in the file
339 lib/silcclient/command.c.
341 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
343 * Imported a modified version of Irssi client to the source tree.
344 The Irssi will be used to create a new client called
345 Irssi SILC. Imported to irssi/.
347 Added silc_core_init_finish function to the Irssi. Affected
348 file irssi/configure.in.
350 A lot changes in the Makefile.ams around the irssi tree.
352 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
354 * Do not rehash if the new size is same as the old size of the
355 hash table, in the silc_hash_table_rehash*. The affected file
356 lib/silcutil/silchashtable.c.
358 * Replaced hash_table_del_by_context calls from the server
359 (when channel->user_list and client->channels) to the
360 hash_table_del as it is sufficient and faster.
362 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
364 * Added silc_hash_table_list, silc_hash_table_get and the
365 SilcHashTableList structure to provide an alternative way to
366 traverse the hash table. The affected files are
367 lib/silcutil/silchashtable.[ch].
369 * Changed the server's idlist routines to use the hash table
370 routines to optimize the code.
372 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
374 * Replaced the client entry's `channel' list and channel entry's
375 `user_list' list to hash tables for optimized lookup. Changed
376 the code to use the hash table interface around the code.
377 Affected file lib/silcd/idlist.[ch].
379 * Added `auto_rehash' boolean argument to the function
380 silc_hash_table_alloc to indicate whether the hash table should
381 auto-rehash when it thinks is appropriate time. It will
382 increase the hash table size if the there is twice as much
383 entries in the table than the size of the table, and will
384 decrease the size if there are twice as less entries than
385 the size of the table.
387 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
389 * Fixed silc_xxx_get_supported to not crash at some circumstances.
391 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
393 * silc_idcache_purge_by_context deletes the entry now by context
394 as it is supposed to do. Affected file lib/silccore/idcache.c.
396 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
397 client is not anymore valid (WHOWAS givens the info) and not
398 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
400 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
402 * Removed the `data' and `data_len' arguments from the ID Cache
403 interfaces and added `name' argument. ID Cache does not handle
404 anymore the binary data only a names associated with given ID.
406 * When hashing a Client ID with silc_hash_id the entire ID is
407 not hashed anymore, instead only the hash of the Client ID is
408 hashed. This way we can access the Client ID from the cache
409 with Client ID but with the hash of the ID (which is a hash of
410 the nickname) as well without any difference in performance.
412 Added also silc_idcache_find_by_id_one_ext to do one on one
413 searching when we have the actual ID. Added also function
414 silc_hash_client_id_compare. The affected files are
415 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
417 * When hashing the name associated with a ID it is always done
418 in lowercase. This way we can access the cache without worrying
419 about case-sensitivity, even though, for example nicknames are
422 * Fixed a bug in server with channel message sending. It put
423 wrong ID type as destination ID. The affected file
426 * silc_idcache_del_by_context now deletes from all hash tables
427 by context. Affected file lib/silccore/idcache.c.
429 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
431 * Changed the client library to use the new ID Cache interface.
432 Changes around the source tree.
434 * Added silc_hash_table_rehash_ext to rehash with specific
435 hash function. Affected file lib/silcutil/silchashtable.[ch].
437 * Added silc_hash_string_compare to compare two strings in the
438 hash table. Affected file lib/silcutil/silcutil.[ch].
440 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
442 * Added new function silc_idcache_del_by_context into the
443 lib/silccore/idcache.[ch].
445 * Changed the server's ID list routines to use the new ID Cache
446 interface. Changes around the source tree.
448 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Added silc_hash_table_del[_by_context]_ext functions in to the
451 lib/silcutil/silchashtable.[ch].
453 Removed silc_hash_table_find_all* routines and added new
454 silc_hash_table_find_foreach to replace them.
456 Added silc_hash_table_replace_ext function as extended
457 replacing function. Separated the simple hash table interface
458 from the extended hash table interface in the file
459 lib/silcutil/silchashtable.h.
461 * Fixed minor bugs and changed it to use some of the new
462 hash table functions in lib/silccore/idcache.c
464 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
466 * Added new function silc_hash_table_find_all to return all keys
467 in the hash table by the specified key. As the hash table is
468 collision resistant it also makes it possible to have several
469 duplicate keys in the hash table. This function may be used to
470 find all of the keys from the hash.
472 Added user_context arguments to the SilcHashFunction,
473 SilcHashCompare and SilcHashDestructor to deliver user specified
476 Added new fuctions silc_hash_table_find[_all]_ext to do
477 extended lookup with specified hash and compare functions and
478 specified user contexts.
480 Added new function silc_hash_table_add_ext to add the key
481 with specified hash function and user context.
483 Added new function silc_hash_table_foreach to traverse all
484 entrys in the hash table. Added SilcHashForeach callback
487 Added new function silc_hash_table_del_by_context to delete
488 the entry only if the context associated with the key matches.
490 Affected files are lib/silcutil/silchashtable.[ch].
492 * Removed silc_hash_[server/client/channel]_id and added just
493 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
494 silc_hash_id_compare to compare two ID's using as the hash table
495 comparison function. Added also silc_hash_data to hash
496 binary data and silc_hash_data_compare to compare it.
498 * Removed silc_idlist_find_client_by_hash as it is not needed
499 anymore. Affected file silcd/idlist.[ch].
501 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
502 to use internally the SilcHashTable. The new ID Cache is a lot
503 faster than the old one. Some of the ID Cache interface was also
504 rewritten and obsolete and stupid functions were removed.
506 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
508 * Added entry_count field to the SilcHashTable to keep the number
509 of the entries in the table. Implemented the function
510 silc_hash_table_rehash. Added new function
511 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
513 Fixed a minor bug in silc_hash_table_free.
515 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
516 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
517 into the lib/silcutil/silcutil.[ch].
519 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * Implemented a collision resistant hash table into the
522 lib/silcutil/silchashtable[ch]. See the header and the source
523 for the SilcHashTable API.
525 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
527 * Merged dotconf version 1.0.2 into lib/dotconf.
529 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
531 * Do not compile anything in lib/silcsim/* if the SIM support
532 is not enabled. The tree should now compile without problems
535 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
537 * Compiled the SILC under cygwin. Compiled and tested briefly
538 without problems. More tests needed. The SIMs didn't compile
541 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
543 * Fixed possible crash in silc_get_username in the
544 lib/silcutil/silcutil.c.
546 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
548 * Fixed a va_arg in silc/client_ops.c.
550 * Oops, RC5 routines were named AES and caused some problems
551 when not using SIM's. Affected file lib/silccrypt/rc5.c.
553 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
555 * Added new SilcIDIP structure into the lib/silccore/id.h and
556 replaced the old `ip' fields from all SILC ID's to that type.
557 This is a step towards IPv6 support.
559 The silc_id_get_len takes now the ID as an extra argument.
560 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
561 both IPv4 and IPv6 based ID's.
563 The affected files are lib/silccore/id.[ch] and other files
564 around the tree using these routines.
566 * Removed the ID length arguments in server from various
567 silc_server_send_notify_* routines -> they are not needed
570 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
572 * Fixed memory leak in silc_encode_pem_file in the file
573 lib/silcutil/silcutil.c.
575 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
577 * Check minor version as well in the SKE. Affected files are
578 silcd/protocol.c and lib/silcclient/protocol.c.
580 * Added --identifier option to the server so that an identifier
581 can be when creating the public key for the server. Affected
582 file is silcd/silcd.c.
584 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
585 lib/silccrypt/silcpkcs.c.
587 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
589 * Register default ciphers and stuff when using -C option with
590 the server. Affected file sildc/silcd.c.
592 * Put back the servers public key filename format, it is better
593 than the new one. For now, the client keys are saved with the
594 new filename format. The affected file silc/client_ops.c.
596 * Implemented the Cipher API for the rest of the ciphers that
597 did not implement it or implemented it the wrong way.
599 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Register default ciphers and stuff when using the -S option
602 in the client. Affected file silc/silc.c. Same also when
603 creating new key pair with -C option.
605 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
607 * Fixed the silc_verify_public_key client operation function to
608 save the public keys differently. The fingerprint is now
609 used as filename and not the hostname. This way also the
610 client keys are saved uniquely and not with hostnames. The
611 affected file is silc/client_ops.c.
613 * Trimmed the silc_hash_fingerprint function to remove extra
614 whitespaces from the end of the fingerprint. The affected
615 file is lib/silccrypt/silchash.c.
619 * Added silc_cipher_register_default function to register all
620 default ciphers. It can be used when configuration files
621 does not exist and the application does not want any specific
622 ciphers in any specific order.
624 The SilcDList is now used as silc_cipher_list dynamically
625 allocated cipher list. Removed the static list all together
626 and now all ciphers must be allocated to the dynamic list.
627 The silc_cipher_alloc routine was changed to check only the
630 All silc_cipher_* routines that used to return int returns
633 The affected files lib/silccrypt/silccrypt.[ch].
635 * The same thing was done to silc_hash_* as for silc_cipher_*
636 routines. Affected files lib/silccrypt/silchash.[ch].
638 * The same thing was done to silc_pkcs_* as for silc_cipher_*
639 routines. Affected files lib/silccrypt/silcpkcs.[ch].
640 Added also silc_pkcs_[un]register[_default] functions.
641 Removed the data_context from the PKCS API.
643 * Added silc_hmac_register_default function to register default
644 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
645 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
646 to unregister all hmacs at once.
648 * Register the default ciphers, hash functions, PKCSs and HMACs
649 if client's configuration file does not exist. The affected
652 * The client did not load the hash functions from the SIM
653 modules at all. Added support for this. Affected file is
656 * When decoding public key with silc_pkcs_public_key_decode, check
657 the supported algorithm only if PKCS are registered. Affected
658 file lib/silccrypt/silcpkcs.c. The same was done with the
659 silc_pkcs_private_key_decode.
661 * Fixed the SILC List routines to keep the list always in order.
662 It used to change the list's order when traversing the list but
663 not it preserves the order. Affected file lib/trq/silclist.h.
665 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
667 * Added the client library to use the SilcSocketConnection's
668 reference counter (by silc_socket_dup) to prevent the bug that
669 the socket object may be freed underneath async operation.
671 * The name resolv library checking fixes in the configure.in.pre.
674 * Created new version of the protocol drafts for future
675 development. The -03 drafts are the ones that will be changed
676 in the trunk now and the -02 will remain as they are.
678 * Send list of CUMODE notifys to the router when announcing
679 the channel users to the router. Affected file silcd/server.c.
680 If the router receiving channel founder CUMODE for a channel
681 that already has channel founder it will send CUMODE notify
682 to the sender to remove the channel founder rights from the
683 announced client. Affected file silcd/packet_receive.c.
685 * The CUMODE notify may now use Server ID as well as the entity
686 who changes the mode. Updated protocool specs.
688 * Updated INSTALL and README files.
690 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
692 * New web pages in the http://silc.pspt.fi. The pages was
697 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
699 * Implemented the [DenyConnectin] config section in the server.
700 Added silc_server_config_denied_conn to check whether incoming
701 connection is denied. Affected file silcd/serverconfig.[ch].
703 * Do not check the ports when checking the incoming configuration
704 data if the port is 0, meaning any. Affected file is
705 silcd/serverconfig.c.
707 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Fixed buffer overflow in silc_string_compare in the file
710 lib/silcutil/silcutil.c.
712 * Fixed double free in silc_server_command_leave in the file
715 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
717 * Fixed the version checking in the server. Affected file is
720 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Fixed the configuration data fetching when accepting new
723 connections in the server. Affected file silcd/server.c.
725 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
727 * Added `sender_entry' argument to the function
728 silc_server_packet_relay_to_channel so that we can check
729 whether some destination actually belongs to the same route
730 the sender belongs (ie, we must not resend the packet to the
731 sender). Affected file silcd/packet_send.[ch].
733 * Added `servername' field to the SilcClientEntry in the server
734 to hold the name of the server where client is from. Affected
735 file is silcd/idlist.h.
737 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
739 * Moved the channel message encrypting in the router betwen
740 router connections from silc_server_channel_message to the
741 silc_server_packet_relay_to_channel since we want to check
742 whether we have anybody channel before encrypting anything.
743 Affected files silcd/packet_[receive/send].c.
745 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
747 * Fixed the [AdminConnection] server config section to support
748 multiple entries. Affected file silcd/serverconfig.c.
750 * Added support into the server to check the validity of the
751 incoming connection before executing any KE or authentication
754 * The connection configuration is now saved to the KE and
755 connection auth protocol contexts and not fetched anymore in
756 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
758 * The local hosts listenning address and port is also resolved
759 now when starting the server. We want to have the socket object
760 to include the real address and port for the listener. Added
761 new function silc_net_check_local_by_sock into the files
762 lib/silcutil/silcnet.[ch].
764 * Fixed a broadcast bug in server -> do not broadcast if we
767 * Fixed a routing bug. Do not route broadcast packets ever.
768 Broadcast packets must be processed always and not routed since
769 they may be destined to some other host than yourself and thus
770 would get routed without no good reason. Affected file is
773 * Added function silc_server_config_is_primary_route to check
774 whether primary router connection has been configured (a router
775 configuration that we are initiating). If there is not, we
776 will assume that there is only two routers in the SILC network
777 and we will use the incoming router connection as our primary
778 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
780 * Changed the order of the broadcasting. Broadcast _after_ the
781 packet has been processed not before. Affected file is
784 * Fixed a [ClientConnection] parsing bug. The port was never
785 parsed correctly thus resulting to port 0. Affected file
786 silcd/serverconfig.c.
788 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
789 argument and did not set the broadcast packet flag. Affected
790 file silcd/packet_send.c. Fixed same bug in the function
791 silc_server_send_notify as well.
793 * If we receive NEW_ID packet for our own ID in the server, ignore
796 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
800 * Removed the nickname from the Private Message Payload.
801 Updated the code and the protocol specs.
803 * Updated protocol specs for submitting to the IETF.
805 * Tweaked the Random Number Generator a bit. Affected file
806 lib/silccrypt/silcrng.c. Exported a new function
807 silc_rng_[global]_add_noise which can be used to add more
810 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Do not parse packets with different timeout when protocol
813 is active -> may cause problem with rekey. Affected file
816 * When server receives signoff notify it must not create
817 new channel key if the client is on any channels since the
818 sender of the signoff notify will create it.
820 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
822 * Added printing of error messages during SKE protocol from the
823 failure packet sent by server during SKE. Affected file
826 * Removed the client's failure_callback handling with timeout
827 and handle it immediately when received.
829 * The SKE library returned wrong type in SUCCESS and FAILURE
830 packets. They must be 32 bit MSB not 16 bit MSB.
832 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
834 * Ok, rewrote the logic of the re-key and now it seems to work.
835 I tested it on high traffic with frequent re-keys without
836 problems. Added hmac_receive (and renamed hmac to hmac_send)
837 in SilcClientConnection in lib/silcclient/client.h and
838 in SilcIDListData in silcd/idlist.h. Also, removed the
839 SilcPacketParserContext's cipher and hmac fields as they are
840 not needed anymore and actually caused some problems when
841 the ciphers and hmac's changed underneath the packet parser.
843 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
845 * If re-key protocol is active then process the incoming packets
846 synchronously since we must assure that icoming packets encrypted
847 with the old key is processed before the new keys is set to
848 use. This is true other packets than for REKEY packets.
849 Affected file silcd/server.c. The same was done to client library
850 as well, affected file lib/silcclient/client.c.
852 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * Fixed bug in client and server to accept the force send if
855 the packet is send from silc_[server/client]_packet_process
856 function. Otherwise the packets are never delivered, oops.
858 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
860 * Disable force sending of packets when REKEY protocol is active.
861 We must assure that no packet is sent directly when rekey is
862 performed. All packets must be sent through packet queue.
863 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
864 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
865 function is silc_[server/client]_packet_send_real to check
868 * Replaced the SIM paths from example config files to
869 /usr/local/modules. Also, make install creates now
870 /usr/local/silc/logs directory to hold all the SILC server
873 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
875 * Made the configure.in.pre work on Solaris. Patch by salo.
877 * Made all ciphers compatible with non-x86 machines. Defined
878 CBC mode macros into lib/silccrypt/ciphers_def.h.
880 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
882 * Fixed the make install.
884 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * When MAC computation fails the silc_packet_decrypt returned 0
887 even though it was supposed to return -1. Fixed this. The
888 affected file is lib/silccore/silcpacket.c.
890 * Do not replace the config files in /etc/silc (in make install)
891 if they already exist. Affected file ./Makefile.am.
893 * Do not send re-key packets immediately but through packet queue.
894 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
896 * Changed silc_net_check_host_by_sock to return FALSE if the
897 IP/DNS could not be resolved. Though, it returns the IP address
898 now even if it could not resolve it (but returns also FALSE).
899 Affected file lib/silcutil/silcnet.[ch].
901 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
903 * Added silc_pkcs_decode_identifier to decode the public key's
904 identifier. Affected file lib/silccrypt/silpkcs.[ch].
905 Added also silc_pkcs_free_identifier. Added also new context
906 SilcPublicKeyIdentifier.
908 * Added -S option to the silc client. It is used to dump the
909 contents of the specified public key file.
911 * Changed the PKCS api to return the public key length when
912 setting the public key.
914 * Fixed a fatal bug in the public and private key file loading.
915 Affected file lib/silccrypt/silcpkcs.c.
917 * Execute the packet parsing for client with zero (0) timeout
918 if the protocol is active. Affected file silcd/server.c.
920 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Made the key generation options to the silcd program. Added
923 -C option, equivalent to client's option.
925 * Added new [ServerKeys] config section to the server. It
926 configures the server's public and private key.
928 * Defined generic Public Key Payload into the protocol
929 specification to send specific type of public keys and
932 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
933 public key or certificate.
935 * Implemented the GETKEY command to the server and to the
936 client library and on user interface.
938 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
940 * Made preliminary `make install' work.
942 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
944 * Added SilcServerRekey context into silcd/idlist.h.
946 * Added the PFS support as defined in the specification to the
947 SKE protocol. Affected files lib/silcske/*.c.
949 * Added `ske_group' field to the SilcServerRekey context to hold
950 the number of the SKE group that is used with PFS in re-key.
951 Affected file silcd/idlist.h.
953 * Added PFS re-key support to the server. Affected file is
956 * Added silc_protocol_cancel to cancel execution of the next
957 state of the protocol. Affected file is
958 lib/silccore/silcprotocol.[ch].
960 * Added the re-key support with and without PFS to the client
961 library. Re-key is performed once in an hour, by default.
963 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
964 Added silc_client_rekey_callback and silc_client_rekey_final.
965 Affected files are lib/silcclient/protocol.[ch] and
966 lib/silcclient/client.[ch].
968 * Removed the `hmac_key' and `hmac_key_len' fields from the
969 SilcClientConnection structure; not needed. Affected file is
970 lib/silcclient/client.h.
974 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
976 * Do not ask whether user wants to use the negotiated private key
977 for private messages, just use it. Affected file is
978 silc/local_command.c.
980 * Added `send_enc_key' and `enc_key_len' fields to the
981 SilcIDListData structure since they are needed in the re-key
982 phase. Affected file is silcd/idlist.[ch].
984 * Implemented the simple re-key protocol into the server.
985 Affected files silcd/server.c and silcd/protocol.[ch]. The
986 re-key will be performed once in an hour, by default.
988 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
989 Added silc_server_rekey, silc_server_rekey_callback and
990 silc_server_rekey_final.
992 * Removed Tunneled flag from the protocol. Updated the code
993 and the specifications.
995 * Adde `pfs' field to the SilcIDListData to indicate whether
996 the PFS is to be performed in the re-key. Affected file is
999 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1001 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1002 int64 of at least the xintXX size. If void * is less that 4
1003 bytes uint32 * will be used. Defined bool as boolean.
1005 * Changed _ALL_ unsigned long and unsigned int to uint32,
1006 unsgined short to uint16 in the source tree.
1008 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1009 not handle clients that has entry->data.registered == FALSE.
1010 They are not in the network anymore. Affected file is
1013 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Implemented the sending of the SERVER_SIGNOFF notify in the
1016 server. Affected file is silcd/server.c.
1018 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1019 Added also silc_notify_payload_encode_args into the
1020 lib/silccore/silcnotify.[ch].
1022 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1023 Affected file silcd/packet_receive.c.
1025 * Implemented the SERVER_SIGNOFF notify handling in the client
1026 library. Affected file lib/silcclient/client_notify.c. Also,
1027 implemnted the printing of the SERVER_SIGNOFF info to the
1028 application. Affected file silc/client_ops.c.
1030 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1031 if the deleting was successful. Affected file silcd/idlist.[ch].
1033 * Added support for public key authentication in the connection
1034 authentication protocol in the client library. Affected file
1035 lib/silcclient/protocol.c.
1037 * Changed the server's silc_idlist_get_clients_by_* interface
1038 to support already allocated array so that new entries may be
1039 added to pre-allocated array. Affected file silcd/idlist.[ch].
1040 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1041 and command replies.
1043 * All command reply functions in the server now calls the
1044 pending command callback even if error occured. This way the
1045 error will be delivered to the client as well. Affected files
1046 silcd/command.c and silcd/command_reply.c.
1048 * Fixed INFO command to return local server's info if no server
1049 was provided. Affected file lib/silcclient/command.c.
1051 * Removed RESTART command for good. Updated the code and the
1054 * Rewrote parts of the task system. It is a bit simpler now.
1055 Removed unsued task priorities. The affected files are
1056 lib/silcutil/silctask.[ch].
1058 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1060 * Moved the USERS printing from the library to the application.
1061 Affected files lib/silcclient/command.c and silc/client_ops.c.
1063 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1067 * Added channel key re-key support. The re-key is perfomed
1068 only by the router and is done once in an hour. Added `rekey'
1069 field to the SilcChannelEntry in the server. Affected files
1070 silcd/server.c and silcd/idlist.h.
1072 * Added silc_task_unregister_by_context into the file
1073 lib/silcutil/silctask.[ch].
1075 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1077 * Added SILC_UMODE_GONE mode to indicate when the client is not
1078 present in the SILC network. Added also support to the local
1079 command AWAY that will set this mode. Added support of showing
1080 "xxx is gone" in WHOIS command. The USERS command shows the
1081 gone status as well.
1083 * Fixed setting server and router operator privileges in the
1084 server's UMODE command. Affected file silcd/command.c.
1086 * Merged the SKE KE1 and KE2 payloads into one payload. The
1087 new KE payload is equivalent to the old KE2 payload.
1089 Cleaned up the SKE Start Payload parsing. It now uses the
1090 simple buffer unformatting to do the parsing. A lot faster
1093 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1094 to the SKE that is used to indicate whether both of the SKE
1095 parties should perform authentication. By default only the
1096 responder performs authentication. By setting this flag also
1097 the initiator must do authentication. By default it is unset
1098 since in normal SKE case, client to server connection, only
1099 the responder should do authentication. When doing SKE between
1100 two clients both should perform authentication. Updated the
1101 code and the protocol specs.
1103 * A little fix to IDENTIFY command in the server. Search the
1104 client first by hash not nickname. Affected file is
1107 * Fixed the silc_client_close_connection to support closing
1108 the client to client connections wihtout deleting too much
1109 data. Affected file lib/silcclient/client.c.
1111 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1112 are received if protocol used to be active but is not anymore
1113 the application would crash due to NULL pointer dereference.
1114 Affected files silcd/server.c and lib/silcclient/client.c.
1116 * Added `hash' field to the SilcClientConnection to include
1117 the hash function negotiated in the SKE protocol.
1119 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1120 to set the channel founder authentication data. A client can
1121 claim the founder rights later by providing the authentication
1122 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1123 This way the channel founder can regain the channel founder
1124 privileges even it is left the channel. This works only on
1125 local server and the client must be connected to the same
1126 server to be able to regain the founder rights. Updated the
1127 protocol specs accordingly.
1129 Added support to the CMODE command in the client to set the
1130 founder auth data. Read the README to see how to set it.
1132 Added support to the CUMODE command to claim the founder
1133 rights. Read the README to see how to do it.
1135 Added support for the founder authentication to the Channel
1136 Entry in the server. Affected file silcd/idlist.h.
1138 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1139 server's CMODE command. Affected file silcd/command.c.
1141 * Added the following new functions into lib/silccore/silcauth.[ch]:
1142 silc_auth_get_method and silc_auth_get_data.
1144 * The server now saves the remote hosts public key to the
1145 SilcIDListData pointer. Affected file silcd/protocol.c.
1147 * The normal server now does not remove the channel entry from
1148 the cache if the founder authentication data is set. It used
1149 to remove it if the founder was the last one on the channel on
1150 the server and left the channel. The auth data is saved and
1151 if the channel is re-joined later the old entry is used with
1152 the old auth data. Affected files silcd/command_reply.c and
1155 * Removed the `pkcs' field from the SilcIDListData structure
1156 in the server; it is not used. Affected file silcd/idlist.h.
1158 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1160 * Fixed packet processing on slow links. Partial packets were
1161 never re-processed because the incoming data buffer was cleared
1162 by the application. Application must not directly clear the
1163 sock->inbuf, the packet processing routines handle it. Fixed
1164 this in client library and in server.
1166 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1168 * Fixed the WHOIS and IDENTIFY send reply function to really
1169 check whether to send list or just one entry. Affected file
1172 * Cleaned up the LEAVE command's channel key distribution. The
1173 affected file silcd/command.c.
1175 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1176 can enforce the channel mode as well. In that case the ID
1177 includes the ID of the server. The code now enforces the
1178 mode change if the router have different mode than the server.
1180 * The notify client operation with CMODE_CHANGE notify can now
1181 return NULL client_entry pointer if the CMODE was not changed
1182 by client. Application must check for this.
1184 * Added <Server ID> argument to INFO command to support server
1185 info fetching by Server ID.
1187 * Added silc_server_announce_get_channel_users to get assembled
1188 packets of channel users of the specified channel. Affected
1189 file silcd/server.[ch].
1191 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1192 was freed underneath the ID Cache.
1194 * Re-announce clients when the server received CHANNEL_CHANGE
1195 notify from the router. Affected file silcd/packet_send.c.
1197 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1199 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1200 crashed since it did not handle the fact that there is no cipher
1201 called "3" and didn't check the error condition. Now fixed.
1203 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1204 flag. It can be used to send message requests.
1206 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1208 * Implemented the RESTART command in the client.
1210 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1211 notice type messages. Added notice printing to the user
1214 * The channel keys are not re-generated if the channel's mode
1215 is PRIVKEY, ie private key on the channel exists. Affected
1216 files silcd/server.c and silcd/command.c.
1218 * Fixed a little bug in channel message delivery when channel
1219 private keys are set in the server. Affected file is
1220 silcd/packet_send.c.
1222 * Changed the setting on channel->on_channel = TRUE from the
1223 silc_client_save_channel_key to the JOIN command reply. The
1224 key payload is not received if the private channel key is set.
1225 Affected file lib/silcclient/command_reply.c and the
1226 lib/silcclient/client_channel.c.
1228 * When the CMODE_CHANGE notify is sent and the channel private
1229 key mode is removed the channel key must be re-generated in
1230 other cells as well. Added this support for the router in the
1231 silcd/packet_receive.c.
1233 * Added new local command NOTICE to send notice message on
1234 channel. Affected file silc/local_command.[ch].
1236 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1238 * Added new local command ME to the client. It is used to send
1239 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1240 some action. Affected file silc/local_command.[ch].
1242 * Changed channel_message and private_message client operations
1243 to deliver the message flags to the application. Added also
1244 the `flags' arguments to the silc_client_send_channel_message
1245 and silc_client_send_private_message functions. Affected file
1248 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1250 * Redefined the Private Message Payload to support private message
1251 keys and to support the new private message flags. Updated
1252 the protocol specs. Flags makes it possible to have for example
1253 CTCP style messages.
1255 * Added new type SilcPrivateMessagePayload and defined an API
1256 for it in the lib/silcclient/silcprivate.[ch].
1258 * Tested private message private keys successfully. Tested the
1259 private message key set, unset and list commands with the new
1262 * Redefined the Channel Message Payload to include the channel
1263 message flags (equal with private message flags) to support
1264 for example CTCP style messages.
1266 * Defined some of the message (for channel and private message)
1267 flags. Updated the protocol specs and added the flags to the
1268 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1270 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1272 * Added SilcKeyAgreementStatus type to the key agreement routines
1273 to indicate the current status and error if one occured.
1274 The status types are defined in the lib/silcclient/silcapi.h.
1276 * Added new local command KEY that is used to set and unset private
1277 keys for channels, set and unset private keys for private messages
1278 with remote clients and to send key agreement requests and
1279 negotiate the key agreement protocol with remote client. The
1280 key agreement is supported only to negotiate private message keys,
1281 it currently cannot be used to negotiate private keys for channels,
1282 as it is not convenient for that purpose.
1284 * Fixed a minor pending callback setting bug in the function
1285 silc_client_get_client_by_id_resolve, now the function works.
1286 Affected file lib/silcclient/idlist.c.
1288 * Added function silc_net_get_local_port to get local bound
1289 port by socket. Added to lib/silcutil/silcnet.[ch].
1291 * Added `sockets' and `sockets_count' fields to the SilcClient
1292 object. They hold the sockets of the listenning sockets in
1293 the client. Listenning sockets may be for example the key
1294 agreement server. Affected file lib/silcclient/client.[ch].
1295 Added functions the silc_client_add_socket and the
1296 silc_client_del_socket. They are exported to the application
1299 * Added ~./silc/clientkeys to support other client's public keys.
1301 * Renamed verify_server_key client operation to verify_public_key
1302 and added one argument to indicate the type of the connection
1303 (server, client etc.).
1305 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1307 * Added silc_server_connection_auth_request to handle the
1308 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1309 silcd/packet_receive.[ch].
1311 * Added silc_server_send_connection_auth_request into the
1312 silcd/packet_send.c to send the connection auth request packet.
1314 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1317 * Fixed the public key authentication in responder side in the
1318 server. The `auth_data' pointer includes the SilcPublicKey
1319 not the path to the public key. Affected file silcd/protocol.c.
1321 * Implemented the public key authentication in the initiator side
1322 in the server. Affected file silcd/protocol.c.
1324 * Removed the [RedirectClient] config section from the server
1325 configuration. Is not needed and I don't want to implement it.
1327 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1329 * Cleaned up the CMODE command in the server. It now works
1330 correctly and supports all the modes defined in the protocol.
1331 Affected file is silcd/command.c.
1333 * Added `hmac_name' field to the SilcChannelEntry in the server
1334 to hold the default HMAC of the channel. It can be set when
1335 creating the channel (with JOIN command). Affected files
1338 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1339 type to indicate the change of the current cipher and hmac
1340 on the channel. Client can safely ignore the <cipher> argument
1341 (if it chooses to do so) since the CHANNEL_KEY packet will
1342 force the channel key change anyway. The <hmac> argument is
1343 important since the client is responsible of setting the new
1344 HMAC and the hmac key into use.
1346 * Fixed the CMODE command in the client library as well.
1348 * Tested CMODE command in router environment successfully.
1350 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1352 * Show the version of the remote client (or server) when connecting
1353 to the server. It is logged to the log file. Affected file
1354 is silcd/protocol.c.
1356 * Fixed the KILLED notify handling in the client library. The
1357 client must be removed from all channels when receiving the
1360 Also, do not remove the client entry when giving the KILL
1361 command but when the KILLED notify is received.
1363 * Removed silc_idlist_find_client_by_nickname from the server.
1364 Not needed anymore. Affected files silcd/idlist.[ch].
1366 * Implemented the CHANNEL_CHANGE notify type handling to the
1367 server. Affected file silcd/server.c.
1371 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1373 * Added silc_server_send_notify_invite to send the INVITE
1374 notify between routers.
1376 * Implemented the INVITE command correctly to the server.
1378 * Implemented the INVITE notify type handling in the server.
1380 * Implemented the INVITE command to the client library and on the
1383 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * Added function silc_server_get_client_resolve to find the
1386 client entry by ID from all ID lists and then resolve it
1387 (using WHOIS) if it cannot be found. Affected file is
1390 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1392 * Implemented the BAN command to the client library.
1394 * The JOIN command in the server now checks the invite list
1397 * Changed the silc_command_reply_payload_encode_va and the
1398 silc_command_payload_encode_va to support that if argument is
1399 NULL it ignores and checks the next argument. Affected file
1400 lib/silccore/silccommand.c.
1402 * Added silc_server_send_notify_ban to send the BAN notify
1403 type between routers.
1405 * Chaned the silc_notify_payload_encode to support that if
1406 argument is NULL it ignores and checks the next argument.
1407 Affected file lib/silccore/silcnotify.c.
1409 * Tested ban lists in router environment successfully.
1411 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * Implemented BAN command to the server, in silcd/command.[ch].
1415 * Removed the BAN and INVITE_LIST modes from the CMODE command
1418 * Added function silc_string_match to regex match two strings.
1419 Affected files lib/silcutil/silcutil.[ch].
1421 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1423 * Redefined parts of the SilcChannelEntry in the server to support
1424 the new ban and invite lists.
1426 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Redefined the INVITE command. The same command can be used to
1429 invite individuals to the channel but also to manage the invite
1430 list of the channel (to add to and remove from the invite list).
1431 Updated the protocol specs.
1433 * Added new command SILC_COMMAND_BAN that can be used to manage
1434 the ban list of the channel. Updated the protocol specs.
1436 * Removed the channel modes: the SILC_CMODE_BAN and the
1437 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1438 in the CMODE command. The equivalent features are now available
1439 using INVITE and BAN commands. Updated the protocol specs.
1441 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1442 in the network about change in the current ban list. The notify
1443 type is not used by the client.
1445 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1446 support the invite lists.
1448 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Added new function silc_string_regexify that converts string
1451 including wildcard characters into regex string that can
1452 be used by the GNU regex library. Added into the file
1453 lib/silcutil/silcutil.[ch].
1455 Added silc_string_regex_combine to combine to regex strings
1456 into one so that they can be used as one regex string by
1457 the GNU regex library. Added into the file
1458 lib/silcutil/silcutil.[ch].
1460 Added silc_string_regex_match to match two strings. It returns
1461 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1463 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1465 * Imported GNU regex to the soruce tree into lib/contrib.
1466 Fixed some compiler warning from the regex.c.
1468 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1470 * Fixed MOTD command in the server to work in router environment.
1472 * Fixed the MOTD command in the client library to support
1473 the server argument in the command.
1475 * Added `nickname_len' argument to the silc_idlist_add_client
1476 in the server, as the `nickname' argument may be binary data
1479 * Added silc_idlist_get_channels to return all channels from
1482 * Implemented LIST command to the server. Affected file is
1485 * Implemented the LIST command to the client library and on the
1488 * Added [<user count>] argument to the LIST command reply.
1489 With private channels the user count is not shown.
1491 * Updated TODO and README.
1493 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1495 * The client entry's data.registered must be TRUE even with
1496 global client entry on global client list. The data.registered
1497 is used to check whether the client is anymore in the network,
1498 for example with WHOWAS command so it must be valid.
1500 * Fixed the WHOWAS command in the server. It now actually works
1501 in router environment. Added function into silcd/command_reply.c
1502 silc_server_command_reply_whowas_save.
1504 * Added silc_idlist_purge function to the silcd/idlist.c
1505 to periodically purge the ID Cache.
1507 * Fixed INFO command in the server. It works now in router
1508 environment. Added <server name> argument to the INFO command
1509 reply. Updated the protocol specs.
1511 * Fixed minor bug in silc_idcache_purge to not purge if the
1512 expire value is zero.
1514 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1515 they were buggy because of the WHOWAS information.
1517 * Fixed local command MSG to handle the async resolving of
1518 the remote client properly. It used to fail the first MSG.
1519 Affected file silc/local_command.c.
1521 * Added `data_len' field to SilcIDCache context.
1523 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1525 * Update TODO. Todo in commands in the server.
1527 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1529 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1530 used by routers as broadcast packet to inform other routers
1531 about the changed user mode.
1533 Implemented the notify handling in the server. Affected file is
1534 silcd/packet_receive.c. Added the function
1535 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1537 * Added new generic Channel Payload and deprecated the New Channel
1538 Payload. The New Channel Payload is now the generic Channel
1541 * Added new argument `mode' to the silc_server_send_new_channel
1542 as it is required in the Channel Payload now.
1544 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1545 and created a new and real SilChannelPayload to represent the
1546 new generic Channel Payload. Implemented the encode/decode
1547 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1549 * Added silc_server_get_client_channel_list to return the list
1550 of channels the client has joined for WHOIS command reply.
1551 Affected file silcd/server.[ch].
1553 * Implemented the channel list sending in the WHOIS command reply
1554 in server and in the client.
1556 Implemented the channel list displaying on the user interface
1557 as well. Affected file silc/client_ops.c.
1559 * Added silc_channel_payload_parse_list to parse list of Channel
1560 Payloads. It returns SilcDList list of SilcChannelPayloads.
1561 Client for example can use this function to parse the list of
1562 channels it receives in the WHOIS command reply. The caller
1563 must free the list by calling silc_channel_payload_list_free.
1564 Affected files lib/silccore/silcchannel.[ch].
1566 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * Added one new argument <user mode> to the WHOIS command reply
1569 to return the mode of the user in SILC. Updated the protocol
1572 Implemented it to the server and client.
1574 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Fixed the mode printing on the user interface on joining.
1577 Affected file silc/client_ops.c.
1579 * Implemented the UMODE command and user modes in general to the
1580 client library and to the user interface.
1582 * Implemented the UMODE command to the server.
1584 * The server now sends UNKNOWN_COMMAND error status if client sends
1585 unknown command. Affected file silcd/command.c.
1587 * All server commands now handle the command identifier the right
1588 way when sending the command reply to the client. The client can
1589 use to identify the command replies with the identifier.
1591 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Added silc_server_get_client_route to resolve the route to
1594 the client indicated by the client ID. Affected file is
1597 * Added silc_server_relay_packet as general function to relay
1598 packet to arbitrary destination. This deprecates functions
1599 like _send_private_message_key, _relay_notify etc. Affected
1600 file is silcd/packet_send.[ch].
1602 Removed silc_server_send_key_agreement,
1603 silc_server_send_private_message_key and
1604 silc_server_packet_relay_notify functions from the file
1605 silcd/packet_send.[ch].
1609 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1610 server. Affected file silcd/packet_receive.[ch].
1612 * Implemented the KILL command to the client. Implemented the
1613 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1614 Affected files lib/silcclient/command[_reply].c and
1615 lib/silcclient/client_notify.c. Implemented the KILL notify
1616 printing in the user inteface.
1618 * Fixed a lot silc_parse_nick memory leaks from the client
1619 library in the file lib/silcclient/command.c.
1621 * Changed the silc_server_send_notify_on_channels's `sender'
1622 argument from SilcSocketConnection to SilcClientEntry to
1623 check the sender as entry and not as connection object and not
1624 to send to the client provided as argument. The affected file
1625 is silcd/packet_send.[ch].
1627 * The notify packets that are destined directly to the client used
1628 to not to be processed by the server. Now changed that and the
1629 server processes all notify packets. After relaying the packet
1630 to the client the notify packet is processed in the server.
1632 * The silc_server_free_client_data now checks whether there is
1633 pending outgoing traffic for the client and purges the data to
1634 the network before removing the client entry.
1636 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1638 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1639 an client is killed from the SILC Network. Updated the protocol
1642 Added new function silc_server_send_notify_killed to the
1643 silcd/packet_send.[ch].
1645 * Added function silc_server_packet_relay_notify to relay notify
1646 packets that are destined directly to a client. In this case
1647 the server does not process the notify packets but merely relays
1648 it to the client. Affected file silcd/packet_send.[ch].
1650 Added also silc_server_packet_process_relay_notify to check
1651 whereto relay the notify. Affected file is
1652 silcd/packet_receive.[ch].
1654 * Implemented the KILL command to the server.
1658 * Added the backup schema desgined last fall to the protocol
1659 specs for everyone to see. The specification is in the
1660 *-spec-xx.txt draft and the packet type definitions for the
1661 backup routers is in *-pp-xx.txt draft. Thusly, added also
1662 new packet type SILC_PACKET_CELL_ROUTERS.
1664 * A big security problem in the implementation discovered. The
1665 signoff of an client did not cause new channel key generation
1666 which it of course should've done. The channel keys must be
1667 always re-generated when client leaves (or signoffs) the channel.
1668 The silc_server_remove_from_channels funtion now handles
1669 the channel key re-generation.
1671 * Added `sender' argument to the silc_server_send_notify_on_channels
1672 to not to send the client provided as argument. Affected file
1673 silcd/packet_send.[ch].
1675 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Implemented OPER and SILCOPER commands into the server and
1680 * Added silc_auth_verify and silc_auth_verify_data to verify
1681 the authentication directly from the authentication payload.
1682 It supports verifying both passphrase and public key based
1683 authentication. Affected file lib/silccore/silcauth.[ch].
1685 * Added `hash' field to the SilcIDListData structure. It is the
1686 hash negotiated in the SKE protocol. Affected file is
1689 * Slight redesigning of the SilcAuthPayload handling routines.
1690 Do not send SilcPKCS but SilcPublicKey as argument.
1692 * Implemented the public key authentication support to the
1693 serverconfig. The public key is loaded from the provided path
1694 and saved as authentication data to void * pointer. Thus,
1695 changed the unsigned char *auth_data to void *auth_data;
1697 * Fixed SHUTDOWN command to send the reply before the server
1698 is shutdown. :) Affected file silcd/command.c.
1700 * Fixed fatal bug in CONNECT command. The hostname was invalid
1701 memory and server crashed. Affected file silcd/command.c.
1703 * Fixed fatal bug in CLOSE command. The server_entry became
1704 invalid but was referenced later in the command. Affected file
1707 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1709 * Fixed fatal bug in failure packet handling. Server ignored
1710 the failure and thus crashed when it came.
1714 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1717 that the command may be executed only once in (about) 2 seconds.
1718 The old SILC_CF_LAG flag is same but allows command bursts up
1719 to five before limiting.
1721 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1722 server code. Various commands now includes the CF_LAG_STRICT
1723 flag to disallow any kind of miss-use of the command.
1725 * Fixed the silc_buffer_unformat to not to allocate any data
1726 if the length of the data is zero. It used to allocate the
1727 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1729 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1731 * Changed the format of AdminConnection configuration section
1732 in the server. Added username of the admin to the format.
1733 Affected files silcd/serverconfig.[ch].
1735 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1736 to return admin configuration data by host, username and/or
1739 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1741 * Implemented WHOWAS command to the server. Added the functions:
1743 silc_server_command_whowas_parse,
1744 silc_server_command_whowas_send_reply,
1745 silc_server_command_whowas_from_client and
1746 silc_server_command_whowas_from_server
1748 * Added <Client ID> argument to the WHOWAS command reply. Updated
1749 the protocol specs accordingly.
1751 * Implemented WHOWAS command and command_reply to the client
1754 Implemented the WHOWAS printing on the user interface.
1756 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1758 * Added new argument to the WHOWAS command reply, the real name.
1759 It is an optional argument. Updated the protocol specs.
1761 * Added SilcIDCacheDestructor callback that is registered when
1762 the SilcIDCache is allocated. The callback is called when
1763 an cache entry in the ID Cache expires, or is purged from the
1764 cache. Added into lib/silccore/idcache.[ch].
1766 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1767 to destruct the client entries when the cache entry expires.
1768 Other ID Cache's in server and in the client library ignores
1771 * If the ID Cache entry's `expire' field is zero then the entry
1772 never expires. Added boolean `expire' argument to the
1773 silc_idcache_add function in the lib/silccore/idcache.[ch].
1774 If it is TRUE the default expiry value is used.
1776 * Added silc_server_free_client_data_timeout that is registered
1777 when client disconnects. By default for 5 minutes we preserve
1778 the client entry for history - for WHOWAS command.
1780 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1782 * Added support to the server to enforce that commands are not
1783 executed more than once in 2 seconds. If server receives
1784 commands from client more frequently, timeout is registered
1785 to process the commands. Affected file silcd/command.c.
1786 Added new function silc_server_command_process_timeout.
1788 * Changed NICK_NOTIFY handling in client library to check that
1789 if the client's nickname was changed, so there is no need to
1790 resolve anything from the server.
1792 * Removed error printing from the WHOIS and IDENTIFY commands.
1793 If error occurs then it is ignored silently in the client library.
1794 The application, however, may map the received error to
1795 human readable error string. The application currently maps
1796 the NO_SUCH_NICKNAME error to string.
1798 * Made the command status message public to the application. Moved
1799 them from lib/silcclient/command_reply.c to
1800 lib/silcclient/command_reply.h. The application can map the
1801 received command status to the string with the
1802 silc_client_command_status_message function.
1804 * Added check to the server to check that client's ID is same
1805 as the Source ID in the packet the client sent. They must
1808 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1810 * Added dist-bzip hook to the Makefile.am to make bzip2
1811 compressed distributions.
1813 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1815 * Server now enforces the maximum length for the nickname and
1816 the channel as protocol specification dictates. 128 bytes for
1817 nickname and 256 bytes for channel name.
1819 * Moved the WHOIS printing to the application. The client libary
1820 does not print out the WHOIS information anymore, the application
1821 must do it. Renamed silc_client_command_reply_whois_print to
1822 the silc_client_command_reply_whois_save.
1824 The client's idle time is also sent to the application now, and
1825 the idle is shown on screen.
1827 * Added silc_client_command_reply_identify_save to save the
1828 received IDENTIFY entries.
1830 * Do not check for channel private keys in message sending and
1831 reception if the channel does not have the PRIVKEY mode set.
1832 Affected file lib/silclient/client_channel.c.
1834 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1836 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1837 just surfaced after chaning the JOIN procedure.
1839 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1841 * Added silc_client_get_clients_by_list to get client entries
1842 from Client ID list, that is returned for example by JOIN
1843 and USERS command replies. The application should use this
1844 function for example when JOIN command reply is received to
1845 resolve the clients already on the channel (library does not
1846 do that anymore as USERS command reply is not used in the JOIN
1847 procedure anymore). Affected files lib/silcclient/silcapi.h and
1848 lib/silcclient/idlist.c.
1850 * JOIN command reply and USERS command reply returns now SilcBuffer
1851 pointers instead of unsigned char pointers when returning
1852 the client list and mode list.
1854 * Added <Client ID> argument to the JOIN command reply, mainly
1855 for the server to identify for which client the command was
1856 originally sent. Updated protocol specs accordingly.
1858 * Added SilcDlist private_key pointer to the SilcChannelEntry
1859 in the client to support the channel private keys. Affected
1860 file is lib/silcclient/idlist.h.
1862 * Added SilcChannelPrivateKey argument to the function
1863 silc_client_send_channel_message so that application can choose
1864 to use specific private ke if it wants to. If it is not provided,
1865 the normal channel key is used, unless private keys are set.
1866 In this case the first (key that was added first) is used
1867 as the encryption key.
1869 * Implemented the support for channel private key handling.
1870 Implemented the following functions:
1872 silc_client_add_channel_private_key,
1873 silc_client_del_channel_private_keys,
1874 silc_client_del_channel_private_key,
1875 silc_client_list_channel_private_keys and
1876 silc_client_free_channel_private_keys
1878 Affected file lib/silcclient/client_channel.c.
1880 * Added the support for the private keys in the channel message
1881 sending and encryption and in the message reception and
1882 decryption. Affected funtions are
1883 silc_client_send_channel_message and silc_client_channel_message.
1885 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1887 * Added SKE's key verify callback to the client library's
1888 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1890 * Removed the statement that server (or router) must send USERS
1891 command reply when joining to the channel so that the client
1892 knows who are on the channel. Instead, the client list and
1893 client's mode list is now sent in the JOIN command reply to the
1894 client who joined channel. This is better solution.
1896 * Added function silc_server_get_users_on_channel and function
1897 silc_server_save_users_on_channel to the silcd/server.[ch].
1899 * Removed function silc_server_command_send_users from the
1902 * Do not show topic on the client library anymore. The topic is
1903 sent in the command reply notify to the application and the
1904 application must show the topic now.
1906 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1908 * Added client searching by nickname hash into the IDENTIFY and
1909 WHOIS commands in the server as they were clearly missing from
1910 them. Affected file is silcd/command.c.
1912 * Fixed a bug in private message receiving in the client library.
1913 The remote ID was freed and it wasn't supposed, now it is
1916 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1918 * Minor fix to the channel payload; allocate the data area, as it
1919 needs to be of specific length.
1921 * If the key agreement port is zero then the operating
1922 system will define the bound port. Affected files are
1923 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1925 * Added new function silc_channel_payload_decrypt into the file
1926 lib/silccore/silcchannel.[ch].
1928 * Moved the channel message etc, check from silc_packet_decrypt
1929 to applications. The library calls now a generic
1930 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1931 when the packet is either normal or special. This was done to
1932 allow more wide range of checking that was not allowed when
1933 the code was in library. Now applications can do virtually any
1934 checks to the packet and return to the library the decision how
1935 the packet should be processed. Affected files are
1936 lib/silccore/silcpacket.[ch].
1938 Added silc_server_packet_decrypt_check to the server and
1939 silc_client_packet_decrypt_check to the client library.
1941 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1942 to send with specified source and destination information.
1944 * Channel message delivery between routers was broken after the
1945 channel key distribution was fixed earlier. The channel key
1946 was used be to distributed to other routers as well which is not
1947 allowed by the protocol. Now this is fixed and channel keys
1948 really are cell specific and the channel message delivery between
1949 routers comply with the protocol specification.
1951 * Fixed various commands in server to check also the global list
1952 for the channel entry and not just the local list. The affected
1953 file silcd/command.c.
1955 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1957 * Added assert()s to buffer formatting and unformatting routines
1958 to assert (if --enable-debug) when error occurs. Affected
1959 file: lib/silcutil/silcbuffmt.c.
1961 * Changed to auto-reconnect to check whether the remote host is
1962 router and register the re-connect timeout if it is. It used
1963 to check that whether we are normal server, but router must do
1964 auto-reconnect with another router as well. Affected file
1967 * Removed the [<key len>] option from CMODE command as the cipher
1968 name decides the key length, nowadays. See the defined ciphers
1969 from the protocol specification.
1971 * Added [<hmac>] option to the CMODE command to define the HMAC
1972 for the channel. Added SILC_CMODE_HMAC channel mode.
1974 * Added [<hmac>] option for the JOIN command so that user can
1975 select which HMAC is used to compute the MACs of the channel
1978 * Added Hmac field to the Channel Message Payload. The integrity
1979 of plaintext channel messages are now protected by computing
1980 MAC of the message and attaching the MAC to the payload. The
1981 MAC is encrypted. Now, it is clear that this causes some
1982 overhead to the size of the packet but rationale for this is that
1983 now the receiver can verify whether the channel message decrypted
1984 correctly and also when private keys are set for the channel the
1985 receiver can decrypt the packet with several keys and check from
1986 the MAC which key decrypted the message correctly.
1988 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1989 lib/silccrypt/silccipher.[ch].
1991 * Added silc_hash_len to return the digest length into the
1992 lib/silcrypt/silchash.[ch].
1994 * Rewrote parts of Silc Channel Payload interface in the
1995 lib/silccore/silcchannel.[ch]. The encode function now also
1996 encrypts the packet and parse function decrypts it.
1998 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2000 * Fixed a minor formatting bug in the SKE's key material processing.
2001 It actually might have processed the keys wrong way resulting
2004 * Redefined the mandatory HMAC algorithms and added new algorithms.
2005 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2006 and hmac-md5 truncated to 96 bits. The mandatory is now
2007 hmac-sha1-96. Rest are optional (including the one that used
2008 to be mandatory). Rationale for this is that the truncated HMAC
2009 length is sufficient from security point of view and can actually
2010 make the attack against the HMAC harder. Also, the truncated
2011 HMAC causes less overhead to the packets. See the RFC2104 for
2014 * Added new [hmac] configuration section. The SKE used to use
2015 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2016 is of course wrong. The official names that must be proposed in
2017 the SKE are the ones defined in the protocol specification
2018 (hmac-sha1-96 for example). The user can configure any hmac
2019 using any hash function configured in the [hash] section. At
2020 least, the mandatory must be configured.
2022 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2024 * Added HMAC list to the SKE proposal list. It has now both
2025 hash algorithm list and HMAC list. This makes the protocol
2026 incompatible with previous versions. The SKE now seems to work
2027 the way it is supposed to work, for the first time actually.
2029 * Defined plain Hash algorithms to the protocol specification.
2032 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2034 * Implemented support for key agreement packets into the server.
2035 Added functions silc_server_key_agreement and
2036 silc_server_send_key_agreement. Other than these functions,
2037 server has nothing to do with this packet.
2039 * Added support for private message key packets into the server.
2040 Added functions silc_server_private_message_key and
2041 silc_server_send_private_message_key.
2045 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2046 called in the protocol's final callback instead in the END
2047 protocol state. This makes a little more sense and in the same
2048 time in client we can use the same protocol routines for normal
2049 key exchange and to key agreement packet handling as well.
2051 * Added to both client's and server's KE protocol context the
2052 SilcSKEKeyMaterial pointer to save the key material. We will
2053 bring the key material to the protocol's final callback by doing
2054 this. The final callback must free the key material.
2056 * Added SKE's packet_send callback into client's KE protocol
2057 context so that the caller can choose what packet sending function
2058 is used. This way we can use different packet sending when
2059 doing normal SKE when doing key agreement packet handling (in
2060 the key agreement packet handling we do not want to encrypt
2063 * Implemented the responder side of the key agreement routines
2064 in the client. The client can now bind to specified port and
2065 accept incoming key negotiation. The key material is passed
2066 to the application after the protocol is over.
2068 * Implemented the processing of incoming Key Agreement packet
2069 in the client. Added function silc_client_key_agreement to
2072 * Implemented the intiator side of the key agreement routines
2073 in the client. The client can now initiate key agreement with
2074 another remote client. The key material is passed to the
2075 application after the protocol is over.
2077 * Created client_keyagr.c to include all the key agreement
2080 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2081 SILC_TASK_CALLBACK except that it is not static.
2083 * Created client_notify.c and moved the Notify packet handling
2084 from the client.[ch] into that file.
2086 * Created client_prvmsg.c and moved all private message and
2087 private message key routines from the client.[ch] into that file.
2089 * Create client_channel.c and moved all channel message and
2090 channel private key routines from the client.[ch] into that file.
2092 * Changed silc_client_get_client_by_id_resolve to resolve with
2093 WHOIS command instead of IDENTIFY command, in the file
2094 lib/silclient/idlist.c.
2096 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * Implemented the SKE's responder side to the Client library.
2100 * When FAILURE is received to the protocol do not trust it
2101 blindly. Register a timeout to wait whether the remote closes
2102 the connection as it should do it, only after that process the
2103 actual failure. This was changed to both client and server.
2105 * Added client_internal.h to include some of the structures
2106 there instead of client.h in lib/silcclient/.
2108 * Added function silc_task_unregister_by_callback to unregister
2109 timeouts by the callback function.
2111 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2113 * Some "Incomplete WHOIS info" errors has been appearing on the
2114 log files. Took away the entry->userinfo check from WHOIS
2115 reply sending. The entry->userinfo is now " " if client did not
2116 provide one. I thought this was fixed earlier but something
2117 is wrong still. Let's see if the error still appears.
2119 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2121 * Fixed a minor bug in the login when the channel key is
2122 re-generated in the server. It used to generate the key in
2123 wrong order and thus caused problems in the channel traffic.
2125 * Fixed a minor bug in channel key distsribution after
2126 KICK command. The key was not sent to the router even though
2129 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2131 * Added silc_ske_process_key_material_data as generic routine
2132 to process any key material as the SILC protocol dictates. The
2133 function is used by the actual SKE library but can be used by
2134 applications as well. This relates to the private message keys
2135 and the channel private keys since they must be processed the
2136 same way the normal SILC session keys. The protocol dictates
2137 this. Affected files: lib/silcske/silcske.[ch].
2139 Added also silc_ske_free_key_material to free the
2140 SilcSKEKeyMaterial structure.
2142 * Defined silc_cipher_set_key function to set the key for
2143 cipher without using the object's method function. The affected
2144 files: lib/silccrypt/silccipher.[ch].
2146 * Implemented silc silc_client_add_private_message_key,
2147 silc_client_add_private_message_key_ske,
2148 silc_client_del_private_message_key,
2149 silc_client_list_private_message_keys and
2150 silc_client_free_private_message_keys functions in the
2153 Added functions silc_client_send_private_message_key to send
2154 the Private Message Key payload and silc_client_private_message_key
2155 to handle incoming Private Message Key payload.
2157 * Added Cipher field to the Private Message Key payload to set
2158 the cipher to be used. If ignored, the default cipher defined
2159 in the SILC protocol (aes-256-cbc) is used.
2161 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2163 * Removed lib/silcclient/ops.h file.
2165 Redefined parts of the SILC Client Library API. Created new
2166 file silcapi.h that deprecates the ops.h file and defines the
2167 published Client Library API. Defined also private message key
2168 API and channel private key API into the file.
2170 This is the file that the application must include from the
2171 SILC Client Library. Other files need not be included by
2172 the application anymore.
2174 * Added new key_agreement client operation callback and also
2175 defined the Key Agreement library API for the application.
2177 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2179 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2180 is used by clients to request key negotiation between another
2181 client in the SILC network. If the negotiation is started it
2182 is performed using the SKE protocol. The result of the
2183 negotiation, the secret key material, can be used for example
2184 as private message key.
2186 Implemented the Key Agreement payload into the files
2187 lib/silccore/silauth.[ch].
2189 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * Redefined ciphers for the SILC protocol. Added some new ciphers
2192 and defined the key lengths for the algorithms. Changed the
2193 code accordingly. The default key length is now 256 bits.
2195 * Fixed SKE key distribution function silc_ske_process_key_material
2196 when the key length is more than 128 bits. The default key
2197 length in SILC is now 256 bits.
2199 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2200 to indicate unsupported algorithm.
2202 * Renamed rijndael.c to aes.c and all functions as well.
2204 * Fixed a long standing channel key setting bug in client library.
2205 Weird that it has never surfaced before.
2207 * Fixed bug in channel deletion. If the entire channel is removed
2208 then it must also delete the references of the channel entry
2209 from the client's channel list as the client's channel entry and
2210 the channel's client entry share same memory.
2212 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2214 * Implemented CONNECT and SHUTDOWN commands in the client.
2216 * Implemented CLOSE command to the client.
2218 * Added the function silc_idlist_find_server_by_name into the
2219 files silcd/idlist.[ch].
2221 Added the function silc_idlist_find_server_by_conn into the
2222 files silcd/idlist.[ch].
2224 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2226 * DIE command was renamed to SHUTDOWN. Updated the both code
2229 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2230 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2232 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2235 * Added function silc_server_create_connection function to create
2236 connection to remote router. My server implementation actually
2237 does not allow router to connect to normal server (it expects
2238 that normal server always initiates the connection to the router)
2239 so the CONNECT command is only good for connecting to another
2242 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2245 or some other client was kicked from the channel.
2247 Implemented the handling of the notify type to both client
2250 Implemented silc_server_send_notify_kicked to send the KICKED
2251 notify. It is used to send it to the server's primary router.
2253 * Implemented the KICK command into server and client.
2255 * Added `query' argument to the silc_idlist_get_client function
2256 to indicate whether to query the client from server or not if
2259 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2260 to indicate that the client is not channel founder.
2264 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2266 * Removed the rng context from SilcPacketContext structure and
2267 changed that the packet routine uses the Global RNG API.
2269 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Added support for quit message that client can "leave" on the
2272 channel when it quits the SILC. It is ditributed inside the
2273 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2275 Added silc_server_free_client_data that will take the
2276 signoff message as argument.
2278 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2280 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * Updated parts of the protocol specification to keep it up
2285 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2287 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2288 payloads in one packet.
2290 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2291 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2292 use now the new List flag.
2294 * Also deprecated the following packet types: REPLACE_ID,
2295 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2297 * Added list support for Notify packet in server.
2299 * Added silc_server_send_notify_channel_change to send the
2300 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2301 the silc_server_send_replace_id.
2303 * Added silc_server_send_notify_nick_change to send the
2304 NICK_CHANGE notify type. Deprecates the function
2305 silc_server_send_replace_id.
2307 * Added silc_server_send_notify_join to send the JOIN notify type.
2308 Deprecates the function silc_server_send_new_channel_user.
2310 * Added silc_server_send_notify_leave to send LEAVE notify type.
2311 Deprecates the function silc_server_send_remove_channel_user.
2313 * Added silc_server_send_notify_cmode and
2314 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2315 types. Deprecates the silc_server_send_set_mode function.
2317 * Added SERVER_SIGNOFF notify type to indicate that server has
2318 quit. This means that all clients on the channel from that
2319 server will drop. This can be also used when netsplit happens.
2321 Deprecated REMOVE_ID packet type since it is not needed anymore
2324 Added silc_server_send_notify_server_signoff to send the
2325 SERVER_SIGNOFF notify type. Deprecates the function
2326 silc_server_send_remove_id.
2328 Added also silc_server_send_notify_signoff to send the
2329 SIGNOFF notify type.
2331 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2332 SILC protocol from this day on. Changed the protocol
2333 specification as well.
2335 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2336 notify type. It is used between routers to notify about
2337 topic changes on a channel.
2339 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2342 * Partly updated the protocol specification to comply with the
2343 changes now made. It is still though a bit outdated.
2345 * The JOIN notify type now takes one extra argument <Channel ID>.
2346 The packet used to be destined to the channel but now the
2347 JOIN type may be sent as list thus it is impossible to
2348 destine it to any specific channel. By adding this argument
2349 it is again possible.
2351 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2353 * Added CREDITS file. The CHANGES and CREDITS file will appear
2354 in the distribution as well.
2356 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2358 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2359 types in the server's silcd/packet_receive.c.
2361 * Implemented CMODE and CUMODE to work in router environment.
2363 * Fixed minor encoding and decoding buglet from the
2364 lib/silccore/silcmode.c.
2366 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2369 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2371 * Changed all SilcConfigServer* and silc_config_server* to
2372 SilcServerConfig* and silc_server_config*, respectively.
2375 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2377 * Associated the ID (client or server ID) to the Authentication
2378 Payload to avoid any possibility of forging. Updated the
2379 protocol specification and the code accordingly.
2381 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2383 * The RSA key length is now save to the RsaKey context in the
2384 key generation process in lib/silccrypt/rsa.c. The key length
2385 is now used to figure out the maximum size of the block allowed
2386 to be encrypted/signed.
2388 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2389 is equivalent to the silc_mp_mp2bin but does not allocate any
2392 * Changed silc_mp_mp2bin API to take length argument. If it is
2393 non-zero then the buffer is allocated that large. If zero, then
2394 the size is approximated using silc_mp_sizeinbase, which however
2397 * Created Global RNG API which is global RNG that application can
2398 initialize. After initializing, any routine anywhere in the
2399 code (including library) can use RNG without allocating a new
2400 RNG object. This was done to allow this sort of use of the
2401 RNG in code that has no chance to allocate RNG object. All
2402 applications currently allocate this and many routines in the
2403 library use this. Affected file lib/silccrypt/silcrng.[ch].
2405 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2406 it to use the Global RNG API.
2408 * Defined Authentication Payload into protocol specification that
2409 is used during SILC session to authenticate entities. It is
2410 used for example by client to authenticate itself to the server
2411 to obtain server operator privileges.
2413 Implemented this payload into the lib/silccore/silcauth.[ch].
2414 Implemented also routines for public key based authentication
2415 as the new protocol specification dictates.
2417 Moved definitions of different authentication methods from
2418 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2420 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2421 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2422 silc_pkcs_verify_with_hash functions into the file
2423 lib/silccrypt/silcpkcs.[ch].
2425 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2427 * The client entry's userinfo pointer must be always valid.
2428 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2429 will fail since it requires the userinfo. Now, the userinfo
2430 is allocated as "" if actual userinfo does not exist. Actually,
2431 it must exist and it is totally Ok to drop client connections
2432 that does not announce the userinfo. However, we will make
2433 this workaround for now.
2435 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2436 to return the remote port by socket.
2438 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2440 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2441 SILC_SERVER_PENDING_EXEC and added an new macro
2442 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2443 data or when error occurs while processing the pending command.
2445 Added new argument `destructor' into silc_server_command_pending
2446 and to the SilcServerCommandPending object. This destructor is
2447 now called after calling the pending callback or if error occurs
2448 immediately. If error occurs the actual pending callback won't
2449 be called at all - only the destructor. The destructor may be
2450 NULL if destructor is not needed.
2452 All this applies for client library code as well. Similar
2453 changes were made there as well for the pending commands.
2455 In the client, the application must now allocate the
2456 SilcClientCommandContext with the silc_client_command_alloc
2459 * Added reference counter to the SilcServerCommandContext. Added
2460 function silc_server_command_alloc and silc_server_command_dup
2463 Same type of functions added to the client library for the same
2466 * Removed the cmd_ident from IDListData away since it is now
2467 global for all connections. It is the command identifier used
2468 in command sending and with pending commands. The affected file
2471 * Added reference counter to the SilcSocketConnection objecet to
2472 indicate the usage count of the object. The object won't be
2473 freed untill the reference counter hits zero. Currently only
2474 server uses this, and client ignores it. The client must be
2475 set to use this too later. The affected files are
2476 lib/silccore/silcsockconn.[ch]. Added also the function
2477 silc_socket_dup to increase the reference counter.
2479 This was mainly added because it is possible that the socket
2480 is removed underneath of pending command or other async
2481 operation. Now it won't be free'd and proper DISCONNECTING
2482 flags, etc. can be set to avoid sending data to connection that
2483 is not valid anymore.
2485 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2486 the connection. After that it sets SILC_SET_DISCONNECTED.
2487 It is, however, possible that the socket data is not still freed.
2488 The silc_server_packet_process now checks that data is not
2489 read or written to connection that is DISCONNECTED. The socket
2490 get's freed when the reference counter hits zero.
2492 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Changed the client operation API: channel_message operation's
2495 `sender' is now the client entry of the sender, not the nickname
2496 and the `channel' is the channel entry, not the channel name.
2498 In the private_message operation the `sender' is now also the
2499 client entry of the sender not the nickname.
2501 Affected file is lib/silcclient/ops.h and all applications
2502 using the client operations.
2504 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Moved the calling of ops->connect() from connect_to_server_final
2507 into receive_new_id functin since that is the point when the
2508 client is actually allowed to send traffic to network. The
2509 affected file is lib/silcclient/client.c.
2511 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2513 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2514 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2515 (if needs broadcasting) instead of broadcasting the packets one
2516 by one which would make a burst in the network traffic.
2518 * Added `broadcast' argument to the functions in silcd/server.[ch]
2519 silc_server_create_new_channel[_with_id] to indicate whether
2520 to send New Channel packet to primary router.
2522 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Added new function into the silcd/server.[ch] files:
2525 silc_server_create_new_channel_with_id to create new channel with
2526 already existing Channel ID.
2528 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2529 lib/silccore/silcpacket.h. This packet is used t send list of
2530 Set Mode payloads inside one packet. Server uses this to set
2531 the modes for the channels and clients on those channels, that it
2532 announced to the router when it connected to it. The protocol
2533 specification has been updated accordingly.
2535 * The silc_server_new_channel did not handle the packet coming
2536 from normal server as it normally does not send that. However,
2537 when it announces its channels it does send it. Implemented
2538 the support for that.
2540 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2541 into the file lib/silccore/id.h.
2543 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2545 * Fixed memory leaks in the functions silc_idlist_del_client,
2546 silc_idlist_del_channel and silc_idlist_del_server in the file
2547 silcd/idlist.c. All of those leaked like a sieve.
2549 * Fixed some small memory leaks in the client's function
2550 silc_client_notify_by_server.
2552 * Added functions into silcd/server.c: silc_server_announce_clients,
2553 silc_server_announce_channels and silc_server_announce_server.
2554 These functions are used by normal and router server to announce
2555 to its primary router about clients, channels and servers (when
2556 router) that we own. This is done after we've connected to the
2559 These functions effectively implements the following packet types:
2560 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2561 and SILC_PACKET_NEW_ID_LIST.
2563 * Added new functions into the silcd/packet_receive.[ch]:
2564 silc_server_new_id_list, silc_server_new_channel_list and
2565 silc_server_new_channel_user_list to handle the incoming
2566 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2568 * Added support of changing Channel ID in the function
2569 silc_server_replace_id. If the server that announces a channel
2570 to the router already exists in the router (with same name but
2571 with different Channel ID), router is responsible to send
2572 Replace ID packet to the server and force the server to change
2573 the Channel ID to the one router has.
2575 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2576 client that the Channel ID has been changed by the router. The
2577 normal server sends this to the client. Client must start using
2578 the new Channel ID as the channel's ID.
2580 Implemented handling of this new type into lib/silcclient/client.c
2581 into the function silc_client_notify_by_server.
2583 * Added new function silc_idlist_replace_channel_id into the files
2584 silcd/idlist.[ch] to replace the Channel ID.
2586 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2588 * Call silc_server_command_identify_check always when processing
2589 the IDENTIFY command in silcd/command.c
2591 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2594 send keepalive packets. The packet can be sent by clients,
2595 servers and routers.
2597 Added function silc_socket_set_heartbeat into the file
2598 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2599 If not set, the heartbeat is not performed. The actual
2600 heartbeat is implemented in the low level socket connection
2601 library. However, application is responsible of actually
2604 Added silc_server_send_heartbeat to send the actual heartbeat
2605 packet into silcd/packet_send.[ch]. Server now performs
2606 keepalive with all connections.
2608 * Added silc_task_get_first function into lib/silcutil/silctask.c
2609 to return the timeout task with shortest timeout. There was a bug
2610 in task unregistration that caused problems. TODO has been
2611 updated to include that task system must be rewritten.
2613 * The client library will now resolve the client information when
2614 receiving JOIN notify from server for client that we know but
2615 have incomplete information.
2617 * Rewrote parts of silc_server_remove_from_channels and
2618 silc_server_remove_from_one_channel as they did not remove the
2619 channel in some circumstances even though they should've.
2621 * Encryption problem encountered in server:
2623 The LEAVE command used to send the Channel Key packet to the
2624 router immediately after generating it. However, the code
2625 had earlier sent Remove Channel user packet but not immediately,
2626 ie. it was put to queue. The order of packets in the router
2627 was that Channel Key packet was first and Remove Channel User
2628 packet was second, even though they were encrypted in the
2629 reverse order. For this reason, MAC check failed. Now, this
2630 is fixed by not sending the Channel Key packet immediately but
2631 putting it to queue. However, this is more fundamental problem:
2632 packets that are in queue should actually not be encrypted
2633 because packets that are sent immediately gets encrypted
2634 actually with wrong IV (and thus MAC check fails). So, packets
2635 that are in queue should be encrypted when they are sent to
2636 the wire and not when they put to the queue.
2638 However, the problem is that the current system has not been
2639 designed to work that way. Instead, the packet is encrypted
2640 as soon as possible and left to the queue. The queue is then
2641 just purged into wire. There won't be any fixes for this
2642 any time soon. So, the current semantic for packet sending
2645 o If you send packet to remote host and do not force the send
2646 (the packet will be in queue) then all subsequent packets to the
2647 same remote host must also be put to the queue. Only after the
2648 queue has been purged is it safe again to force the packet
2651 o If you send all packets immediately then it safe to send
2652 any of subsequent packets through the queue, however, after
2653 the first packet is put to queue then any subsequent packets
2654 must also be put to the queue.
2656 Follow these rules and everything works fine.
2658 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2660 * Added new function silc_server_remove_clients_by_server to
2661 remove all client entries from ID list when the server connection
2662 is lost. In this case it is also important to invalidate all
2663 client entires as they hold the invalid server entry. This
2664 fixes fatal bug when server has lost connection and will reconnect
2667 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Made some sanity checks to silc_server_daemonise like to check
2670 whether the requested user and group actually exists.
2672 * Added sanity check to SKE's silc_ske_responder_finish to check
2673 that the public and private key actually is valid.
2675 * Invalidate the client's nickname when receiving Replace ID
2676 packet and the Client ID is being replaced. This means that the
2677 server will query the nickname if someone needs it (client)
2680 * Sort the ID Cache in client library when the ID Cache data
2681 has changed (needs sorting).
2683 * Do not allow for SILC client to create several connections to
2684 several servers. The client does not support windows right now
2685 and generating multiple connections causes weird behaviour.
2687 Irssi-silc client does support windows and can handle several
2688 connections without problems, see: www.irssi.org and SILC plugin.
2690 * Fixed some places where client was added to the IDList. The
2691 rule of thumb is following (in order to get everything right):
2692 If the client is directly connected local client then the
2693 `connection' argument must be set and `router' argument must be
2694 NULL to silc_idlist_add_client function. If the client is not
2695 directly connected client then the `router' argument must
2696 bet set and the `connection' argument must be NULL to the
2697 silc_idlist_add_client function.
2699 * The funtion silc_server_packet_send_local_channel actually did
2700 not check whether the client was locally connected or not. It
2701 does that now. Fixed a bug related to LEAVE command.
2703 * Fixed Remove Channel User payload parsing bug in server's
2704 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2706 * The server's silc_server_save_channel_key now checks also the
2707 global ID list for the channel as it might not be in the local
2708 list. Fixed a bug related to LEAVE command.
2710 * Is this the end of the [<unknown>] buglet that has been lurking
2711 around for a long time? A little for loop fix in server's
2712 silc_server_command_whois_parse that is used by both IDENTIFY
2713 and WHOIS command. At least, this was a clear bug and a cause
2714 of one type of [<unknown>] buglet.
2716 * WHOIS and IDENTIFY commands call the function
2717 silc_server_command_[whois/identify]_check function even if
2718 we are not router server.
2720 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2722 * Added --with-gmp configuration option. If set the GMP
2723 is always compiled in the SILC source tree. If not set then
2724 it is checked whether the system has the GMP3 installed. If
2725 it has then the GMP won't be compiled (the system's headers
2726 and library is used), if it doesn't have it then the GMP is
2727 compiled in the SILC source tree.
2729 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * Changed RSA private exponent generation to what PKCS #1
2732 suggests. We try to find the smallest possible d by doing
2733 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2734 not security fix but optimization.
2736 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2738 * Added new config entry [Identity] to fork the server and run
2739 it as specific user and group. A patch from Bostik.
2741 * Imported Dotconf configuration library into lib/dotconf.
2742 This will be used to create the SILC configuration files later.
2743 It will appear in the distsribution after this commit.
2745 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * A big code auditing weekend happening. Auditing code for
2748 obvious mistakes, bugs and errors. Also, removing any code
2751 Removed files for being obsolete:
2753 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2754 inline in the file lib/silcutil/silcbuffer.h)
2756 o lib/silcutil/silcbufutil.c (the header has inline versions)
2758 Changed code to fix possible error conditions:
2760 o The buffer formatting routines now check that the destination
2761 buffer really has enough space to add the data. This applies for
2762 both buffer formatting and unformatting
2763 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2764 unformatting was changed to accomodate following rules:
2765 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2766 sent to the function while XXX_*STRING will not allocate or copy
2767 the data into the buffer. Instead it sets the pointer from the
2768 buffer into the pointer sent as argument (XXX_*STRING used to
2769 require that the pointer must be allocated already). This change
2770 makes this whole thing a bit more consistent and more optimized
2771 (note that the data returned in the unformatting with XXX_*STRING
2772 must not be freed now). The routines return now -1 on error.
2774 o Tried to find all code that use buffer_format and buffer_unformat
2775 and added return value checking to prevent formatting and
2776 especially unformatting errors and possible subsequent fatal
2779 o Changed ske->x and ske->KEY to mallocated pointers in
2780 lib/silcske/silcske.h. Fixed possible data and memory leak.
2782 o Added return value checking to all *_parse* functions. Fixed
2783 many memory leaks as well.
2785 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2786 so that buffer overflows would not happen. All code now also
2787 checks the return value as it can fail.
2789 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Added reconnection support to server if the normal server looses
2792 its connection to the router (for example if router is rebooted).
2793 The server performs normal reconnection strategy implemented
2794 to the server. Affected file silcd/server.c.
2796 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2798 * Added new packet type SILC_PACKET_SET_MODE that is used to
2799 distribute the information about changed modes (for clients,
2800 channels and clients channel modes) to all routers in the
2801 network. Updated the protocol specification accordingly.
2803 Added functions into silcd/packet_send.c and
2804 silcd/packet_receive.c: silc_server_send_set_mode,
2805 silc_server_set_mode.
2807 Added new files silcmode.[ch] into lib/silccore that implements
2808 the encoding and decoding of Set Mode Payload. Added new type
2809 SilcSetModePayload. Moved the definitions of different modes
2810 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2812 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2814 * Oops, a little mistake in server's connection authentication
2815 protocol. The protocol is not ended with FAILURE but with
2816 SUCCESS if the authentication is Ok. :) Affected file is
2819 * Implemented NICK_CHANGE notify handling in server in the file
2820 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2821 the local clients on the channel. After the changing nickname
2822 in router environment snhould work and the [<unknown>] nickname
2823 should appear no more.
2825 The silc_server_replace_id function that receives the Replace ID
2826 payload now sends the NICK_CHANGE notify type also in the file
2827 silcd/packet_receive.c
2829 * Changed WHOIS and IDENTIFY command to support the maximum amount
2830 of arguments defined in protocol specs (3328 arguments). This
2831 fixed a bug that caused problems when there were more than three
2834 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2836 * Added extra parameter, command identifier, to the
2837 silc_client_send_command so that explicit command identifier
2840 Changed that ID list routines uses specific command identifier
2841 when sending WHOIS/IDENTIFY requests to the server so that they
2842 can be identified when the reply comes back.
2844 Affected files lib/silcclient/command.[ch],
2845 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2847 * Added `sender' argument to silc_server_packet_send_to_channel
2848 to indicaet the sender who originally sent the packet to us
2849 that we are now re-sending. Ignored if NULL. Affected file
2850 silcd/packet_send.[ch].
2852 * Added some server statistics support in silcd/server_internal.h
2853 SilcServerStatistics structure and around the server code. Also
2854 send some nice statistics information when client is connecting
2857 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Fixed channel ID decoding in server's JOIN command reply in
2860 silcd/command_reply.c
2862 * Fixed braodcasting of replace ID payload to not to send it if
2863 we are standalone server in silcd/packet_receive.c.
2865 * Fixed all channel message sending routines to not to send
2866 packets to clients that has router set, since they are routed
2867 separately in the same function earlier. Affects file
2868 silcd/packet_send.c and all channel packet sending functions.
2870 * In USERS reply, res_argv[i] are not allocated, the table
2871 is allocated. Thus changed that free the table, not its
2874 * In server's whois_check and identify_check if the client is
2875 locally connected do not send any WHOIS commands - they are not
2878 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2880 * Fixed some minor bugs in client when sending WHOIS command. The
2881 arguments was in wrong order.
2883 * Removed statis function add_to_channel from server in
2884 silcd/command.c that was previously used with the joining but
2887 * Tested USERS command in router environment successfully with two
2888 routers, two servers and two clients.
2890 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Reorganized the USERS command and command reply in client library
2893 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2894 When the command is given by user we register a pending command
2895 callback that will reprocess the command after the reply has been
2896 received from the server. When reprocessing the packet we then
2897 display the information. Thus, the USERS information is displayed
2898 now in the command callback instead of in the command reply
2899 callback. The processing of the command is same as previously
2900 when server has sent the command reply in the JOINing process.
2902 * Added to USERS command in silcd/command_reply.c to join the client,
2903 we didn't use to know about, to the channel after we've created
2904 a client entry for it. Also, for clienet we did know already still
2905 check whether it is on the channel or not and add it if not.
2907 * Removed silc_server_command_join_notify as the function and its
2910 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2912 * Changed the client's pending command handling to the same as the
2913 server's pending command handling. It is also now possible to
2914 execute command reply functions from other command reply
2915 function as the function callbacks for commands and command
2916 replies are one and same. The pending commands are not static
2917 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2918 in client connection context. Thus, pending commands are server
2919 connection specific as it is convenient.
2921 Changed the function silc_client_command_pending and
2922 silc_client_command_pending_del and added new function
2923 silc_client_command_pending_check. Removed the
2924 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2927 * Added cmd_ident, current command identifier, to the client
2928 connection context in lib/silcclient/client.h to keep track on
2929 command identifiers used in command sending. Client's command reply
2930 function handling now supports the mandatory command identifiers.
2932 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2933 funtions in client to fully support pending command callbacks.
2935 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2936 as one of the arguments to the application in the command reply
2939 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2940 before first releasing SILC but came back. Now it is removed again
2941 and should come back nomore. The FORWARDED flag was used only
2942 by the JOINing procedure by forwarding the command packet to router.
2943 Now, the JOINing procedure has been changed to more generic (due
2944 to various router environment issues) and FORWARDED is not needed
2945 anymore for anything. The protocol specification is yet to be
2948 Now, removed silc_server_packet_forward from server and the flag
2949 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2951 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Renamed NAMES command to USERS command. The NAMES was named that
2954 due to historical reasons. Now it is renamed. Also, rewrote
2955 parts of the USERS command. The nickname list is not sent anymore
2956 by the server. Only Client ID and mode lists are sent in the USERS
2957 command. Changed this also to the protocol specification.
2959 The client now resolves the names and stuff after it receives
2960 the USERS list from the server when joining to the channel.
2962 * WHOIS and IDENTIFY commands has been changed to support multiple
2963 Client ID's per command. One can now search for multiple users
2964 in the network by sending only one WHOIS or IDENTIFY command.
2965 Changed the code and the protocol specifications.
2967 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2968 uses silc_server_command_whois_parse to parse the request. */
2970 * If normal server, do not parse the WHOIS and IDENTIFY requests
2971 before sending it to the router. Saves some time.
2973 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Fixed JOIN command on client library. Wrong number of arguments
2976 used to crash the client.
2978 * Added silc_server_channel_has_global function to check whether
2979 channel has global users or not.
2981 * Added silc_server_channel_has_local function to check whether channel
2982 has locally connected clients on the channel.
2984 * The silc_server_remove_from_one_channel now checks whether the
2985 channel has global users or not after given client was removed from
2986 the channel. It also checks whether the channel has local clients
2987 on the channel anymore. If it does not have then the channel entry
2988 is removed as it is not needed anymore.
2990 * The silc_server_notify now checks on JOIN notify whether the joining
2991 client is one of locally connected or global. If it is global then
2992 the channel has now global users on the channel and that is marked
2993 to the channel entry. Also, it now saves the global client to
2994 global list who is joining and JOINs it to the channel. This is
2995 for normal server, that is.
2997 Changed silc_server_send_notify_on_channel,
2998 silc_server_packet_relay_to_channel and
2999 silc_server_packet_send_to_channel check if we are normal server
3000 and client has router set (ie. global client) do not send the
3001 message to that client, as it is already routed to our router.
3003 * Implemented LEAVE notify type handling in silc_server_notify
3006 * Tested LEAVE command in router environment successfully. Tested
3007 with two routers, two servers and two clients.
3011 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3013 * Implemented SIGNOFF notify type handling in silc_server_notify
3016 * silc_server_remove_id now removes the client entry from all channels
3017 it has joined and thusly sends SIGNOFF notify type.
3019 * Rewrote the NAMES list generation in server by removing two excess
3020 loops. The lists are created now inside one loop.
3022 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * silc_server_remove_channel_user checks now also global list
3025 for channel and client.
3027 * silc_server_new_channel_user checks now both local and global
3028 list for channel and client. Fixed a bug in client id decoding.
3029 Used to decode wrong buffer.
3031 * silc_server_channel_message checks now both local and global
3032 list for channel entry.
3034 * Tested channel joining (hence JOIN) in router environment
3035 successfully. Tested with two routers, two servers and two
3038 * Tested channel message sending in router environment successfully.
3040 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3042 * Added silc_server_save_channel_key into server.[ch] to save the
3043 received channel key in Channel Key payload processing. It is
3044 also used in JOIN command reply handling.
3046 Equivalent function silc_client_save_channel_key added into
3047 client.[ch] into client library.
3049 * Changed JOIN command reply to send information whether the channel
3050 was created or not (is existing already) and the channel key
3051 payload. Changed protocol specs accordingly.
3053 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3054 the request was sent by ID and not by nickname. Crashed on
3057 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3059 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3060 now correctly save the received data.
3062 * silc_server_free_sock_user_data now notifies routers in the
3063 network about entities leaving the network.
3065 At the same time implemented functions silc_server_remove_id
3066 and silc_server_send_remove_id to receive and send REMOVE_ID
3067 packets. The packet is used to notify routers in the network
3068 about leaving entities. The ID removed will become invalid in
3071 * Added function silc_idlist_del_server into server. Removes and
3072 free's server entry from ID list.
3074 * silc_server_private_message function now checks, if we are router,
3075 that the destination ID really is valid ID, naturally.
3077 * In router when NEW_ID packet is received (for new client) the
3078 hash of the Client ID is saved in the ID Cache but the
3079 client->nickname is set to NULL, instead of putting the hash
3082 IDENTIFY command now also checks that client->nickname must be
3083 valid. If it is not if will request the data from the server who
3084 owns the client. Added new function
3085 silc_server_command_identify_check.
3087 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3088 to set the command to already allocated Command Payload.
3090 * Tested private message sending in router environment with two
3091 routers, two servers and two clients. Fixed minor bugs and now
3094 * Fixed segfault from client's NAMES command. Used to crash if
3097 * Forwarded packets must not be routed even if it is not destined
3098 to the receiver. Changed server code comply with this.
3100 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Added `require_reverse_mapping' boolean value to ServerParams
3103 structure. If TRUE (not default) the server will require that
3104 the connecting host has fully qualified domain name.
3106 If the reverse mapping is not required and hostname could not be
3107 found the IP address is used as hostname.
3109 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * Implemented version string checking to both client and server.
3112 The check is incomplete currently due to the abnormal version
3113 strings used in development version of SILC.
3115 * Changed all command functions in server to use the new
3118 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Changed char *data to unsigned char *data in ID Cache system to
3121 support binary data as ID Cache data. Changed code to support
3122 binary data in lib/silccore/idcache.c.
3124 * Renamed silc_server_packet_relay_command_reply to
3125 silc_server_command_reply as it is normal packet receiving
3126 function. Rewrote the function to accept command replys for
3127 servers and not only for clients.
3129 * Mark remote router always as registered server if we are connecting
3130 to it. Otherwise, commands sent by the router to us are ignored.
3132 * All ID List find routines now returns the ID Cache Entry pointer
3133 as well if requested.
3135 * WHOIS command works now in router environment, tested with two
3136 routers, two servers and two clients.
3138 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3139 in router environment (as it is almost equivalent to WHOIS) but
3140 hasn't been tested thoroughly. Added new functions:
3142 silc_server_command_identify_parse
3143 silc_server_command_identify_send_reply
3144 silc_server_command_identify_from_client
3145 silc_server_command_identify_from_server
3147 * Disabled route cache adding because adding two different ID's with
3148 same IP replaces the old cache entry thus giving wrong route.
3149 The entry->router->connection is always the fastest route anyway
3150 so route cache may not be needed. Of course, new routes maybe
3151 established after receiving the ID when the entry->router->connection
3152 might not be anymore the most optimal.
3154 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Add route cache for received ID for fast routing.
3158 * Added silc_server_packet_route to route received packet on router
3159 that is not destined to us.
3161 * Renamed silc_server_get_route to silc_server_route_get.
3163 * Added id_string and id_string_len fields into SilcServer to
3164 include encoded ServerID for fast comparing without excess
3165 encoding of the ID's.
3167 * Cleaned up WHOIS command on server side. Added following static
3170 silc_server_command_whois_parse
3171 silc_server_command_whois_check
3172 silc_server_command_whois_send_reply
3173 silc_server_command_whois_from_client
3174 silc_server_command_whois_from_server
3176 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3177 arguments in command replies. All command functions should be
3178 updated to use this macro.
3180 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Minor typo fixes on command reply handling on server.
3184 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Added silc_server_command_add_to_channel internal routine to add
3187 the client to the channel after router has created the channel and
3188 sent command reply to the server.
3190 * Added generic silc_server_send_command to send any command from
3193 * Use static buffer with ID rendering instead of duplicating data.
3195 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * Fixed a channel user mode bug when joining to a channel server gave
3198 everybody channel founder rights, oops.
3200 * We mark ourselves as the router of the incoming server connection
3201 if we are router ourselves. This way we can check in some packet
3202 sending functions whether it is locally connected server. For
3203 incoming router connections we put NULL.
3205 * For router sending packets locally means now always sending the
3206 packet cell wide; to local clients and local servers. For normal
3207 server sending packet locally means sending it to only local
3210 * Fixed the JOIN command to really work in router environment. If the
3211 channel is created it is always created by the router. Router is
3212 also responsible of making the initial joining to the channel,
3213 sending JOIN notify to the sending server and distributing
3214 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3215 does not exist server doesn't do anything else but forward the
3216 command to the router which performs everything.
3218 * Added silc_server_send_channel_key function to send the Channel Key
3221 * Added silc_server_create_channel_key to create new channel key. The
3222 channel key is now re-generated everytime someone joins or leaves
3223 a channel, as protocol dictates. Note: channel->key_len is the
3226 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3229 packet_receive.[ch] to separate packet sending and receiving
3230 routines. The server.[ch] now includes everything else including
3231 actual packet processing (writing and reading data) and other
3234 Renamed silc_server_private_message_send_internal to
3235 silc_server_send_private_message. The routine is still though
3236 used only to relay private messages as server does not send
3237 private messages itself.
3239 Renamed silc_server_new_channel to silc_server_create_new_channel
3240 and added new function sicl_server_new_channel that handles the
3241 incoming New Channel packet. Added also new sending function
3242 silc_server_send_new_channel to send New Channel Payload.
3244 * Added new function silc_server_notify to process incoming notify
3245 packet to the server/router. Server may then relay the notify
3246 to clients if needed.
3248 * Added new function silc_server_new_channel_user to process incoming
3249 New Channel User packet. Router will redistribute the packet and
3250 send JOIN notify to its local clients and locally connected servers
3251 if needed. Normal server will send JOIN notify to its local client
3252 on same channel when received this packet. Added also corresponding
3253 sending function silc_server_send_new_channel_user to sent the
3256 * Added boolean route argument to send_notif_to_channel and
3257 packet_send_to_channel functions to attempt to route the packet
3258 if it is TRUE and send only locally if it is FALSE.
3260 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * silc_server_replace_id now broadcasts the received replace ID
3263 packet if it is not broadcast packet already. The router must
3264 broadcast to inform other routers about changed ID.
3266 * Added backpointer to server's router into SilcServer context in
3267 silcd/server_internal.h.
3269 * Fixed silc_server_packet_broadcast to send correct broadcast
3272 * The channel key is now distributed to the local client as soon
3273 as it is received from the router (in router environment) so that
3274 no other packet may be sent for the channel until client has
3277 * silc_server_remove_channel_user now broadcasts the received
3278 Remove Channel User packet if it is not broadcast packet already.
3279 The router must broadcast to inform other routers about removed
3282 * Added users field into SilcPacketContext that is a reference count
3283 of the context. One can increase the reference count by calling
3284 silc_packet_context_dup which is now changed to just increase the
3285 reference count instead of duplicating the data. The reference
3286 count is decresed by calling silc_packet_context_free that will
3287 free the data after the reference count hits zero.
3289 For now on the packet context and everything allocated into it
3290 (including the raw packet from network) must be freed by calling
3291 the new silc_packet_context_free function. Added also new function
3292 silc_packet_context_alloc that must be used now to allocate the
3293 context. This also means that if a routine is asynchronous from
3294 silc_[client/server]_packet_parse_type the packet context must
3295 be duplicated by calling silc_packet_context_dup. Otherwise it
3296 gets free'd after silc_[client/server]_packet_parse_type returns.
3297 Also, one must remember that if packet is duplicated then its
3298 reference count must be decresed by calling the free function as
3299 many times as it was duplicated.
3301 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3302 from both client and server.
3304 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Made joining to a channel working in router environment.
3308 * Cleaned up JOIN command on server side and create function
3309 silc_server_command_join_channel internal routine to make the
3312 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Changed silc_command_pending list to SilcDList. Also, added
3315 `ident' field to SilcServerCommandPending structure to identify
3316 the reply and to call correct callback.
3318 Added silc_server_command_pending_check function to replace the
3319 corresnponding macro. The silc_command_pending list is not
3322 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3323 to set identifier to previously allocated Command Payload. It
3324 is used to set identifier for command when resending Command
3327 * Added silc_command_payload_encode_payload to encode Command
3328 Payload buffer from SilcCommandPayload structure.
3330 * Added silc_argument_payload_encode_payload to encode Argument
3331 payload buffer from SilcArgumentPayload structure.
3333 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3335 * Changed WHOIS command to support router connection on server side.
3336 The whois request is always sent to router unless the server is
3337 standalone server. After server has received the reply from the
3338 router will it send the reply to the client.
3340 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3341 broadcast received broadcast packet. The function is used only
3342 by router. The broadcast packet is always sent to the router's
3345 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3346 render given ID to printable string, for log files for example.
3348 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3350 * Made basic router to router connections working. At least they
3351 can now connect to each other but nothing really works the way
3352 they are supposed - yet.
3354 * Added new initiator token to RouterConnection configuration
3355 file in silcd/serverconfig.[ch]. It is used to tell whether we
3356 are the initiator to the remote router or whether we'll expect
3357 the other end to connect.
3359 * Moved registering of listener task to silc_server_init, hence
3360 the server starts listenning as soon as it is run, even if it
3361 does not have connections to other routers. Let's see how well
3364 * Changed default connection retry timeouts for more suitable in
3367 * Removed cipher and such arguments from silc_idlist_add_client
3368 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3369 Added new function silc_idlist_add_data to add the keys and stuff
3372 * Added SilcIDListData structure and added it to SilcClientEntry
3373 and SilcServerEntry as their first field in the structure. This
3374 way we can explicitly cast the ID entries to the SilcIDListData
3375 structure and get common data for the entries. In past, we had
3376 to first check what type of connection it is and then cast it to
3377 correct ID entry type. Now, we can directly cast the opaque
3378 pointer to the SilcIDListData (no matter what ID entry it actually
3379 is) and get the data needed.
3381 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3384 in some circumstances even if threre were timeout tasks, though not
3385 IO tasks, but tasks anyway. Now fixed.
3387 * Defined SilcServerConnection structure to hold connection specific
3388 stuff about directly connected servers and routers. The definition
3389 is currently in silcd/server_internal.h. I thought about having
3390 a bit more important role fro this struct but for now it is used
3391 only when connecting to other server (or router actually).
3393 * Added connecting retry support in server when connecting to
3394 router(s). The retry feature implement exponential backoff
3395 algorithm. Also, added SilcServerParams structure to hold default
3396 parameters for server. For now, it include these retry settings
3397 and are hard coded. After server is moded to be as Silc Server
3398 Library this structure will be more important.
3400 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Changed client librarys channel->clients table to SilcList and
3403 changed code accordingly.
3405 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Changed client's channel table to SilcList and changed code
3408 accordingly. Also changed SilcChannelClientEntry to include back-
3409 pointer to the channel so that client entry can use that structure
3410 as list as well and we have fast cross-reference to the channel.
3411 This change dramatically decreased the complexity of channel
3412 handling with client entry and vice versa (removed one extra
3413 loop when searching for channel entry from many functions).
3415 * Changed server->sim from table to SilcDList and changed code
3418 * NAMES command can now be used from user interface. It will show
3419 the user list on the channel, neatly.
3421 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3422 Code now saves realname of the user if it becomes available.
3424 * Renamed configure.in to configure.in.pre and made ./prepare
3425 script to automatically add correct version string to
3426 configure.in which it creates from configure.in.pre.
3428 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * NAMES command reply now shows users mode with the nickname when
3433 * Moved silc_client_ch[u]mode[_char] functions from
3434 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3435 place sucks, they are utility functions and should be in some
3438 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3440 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3443 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Added TRQ (efficient deque and list library) into lib/trq. This is
3448 a very good list library that is currently used in the SILC. Defined
3449 SilcList API over the library because I didn't like the API very
3450 much. See lib/trq/silclist.h for the API and examples of how to
3451 use the API. Fixed various places in the code to use the new
3452 SilcList API. The SilcList is meant for lists that has a structure
3453 already defined as a list. It is not suitable to add just some
3454 context to the list (in TRQ, the context is the list actually).
3456 So, I defined SilcDList that can be used for the purpose where
3457 predefined list structure does not exit. This can be used as
3458 such list. Now some context just can be added to the SilcDList.
3459 Currently this list is not used in the SILC just yet, though there
3460 are a lot places where this can replace dynamically allocated
3461 tables and I will fix these places, later, to use SilcDList.
3462 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3463 and use TRQ internally).
3465 Also fixed some annoying warning messages that the original TRQ
3466 code generated. Also minor changes to TRQ's Makefile.in.
3468 * Added support for querying by Client ID to both WHOIS and
3469 IDENTIFY commands into server, as required by the protocol.
3471 * Removed method function pointers from SilcBuffer structure. They
3472 weren't used to anything and just increased the context size for
3473 no good reason. This change also made silc_buffer_alloc and
3474 silc_buffer_free functions inline functions.
3476 * Disabled command flooding detection support until it's fixed so
3477 that it accepts commands in but does not execute them more than once
3480 * Added silc_net_localhost(), to return local hostname, into
3481 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3482 that must be initialized before calling silc_client_init.
3484 * Added new function: silc_server_send_notify_on_channels to send
3485 notify messages to all channels client has joined. It is assured
3486 that the message is sent only once per client.
3488 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3489 lib/silcutil/silcutil.[ch] as silc_format function. The new
3490 function is generic and is used by server as well, not only by
3491 the logging routines.
3493 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3494 the provided version string was not acceptable. Added new function:
3495 silc_ske_check_version into lib/silcske/silcske.h. The function
3496 must be implemented by the application (client or server) and it
3497 does not reside in the SKE library. The function checks the version
3498 string remote end sent.
3500 * Added back pointers (to opaque context and to SilcSocketConnection)
3501 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3503 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3504 duplicate packet context structure.
3506 * Changed `notify' client operation to send same arguments as client
3507 receives from server except for ID's. ID's are mapped to correct
3508 ID entry and that is returned. Also, if channel entry is not sent
3509 by server but the notify is for channel the channel entry is sent
3510 to application (otherwise application doesn't know that it is for
3511 channel (library gets it from packet's Destination ID)).
3513 * Added silc_client_remove_from_channels into client library to
3514 remove a client from all channels it has joined to. Used when
3515 received SIGNOFF notify from server. Added also new function
3516 silc_client_replace_from_channels to replace old ID entry with
3517 new ID entry on all channels. Used when received NICK_CHANGE
3520 * Fixed ID Cache list handling in silc_idlist_get_client in
3521 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3522 to get (or query) client by ID.
3524 * Updated TODO list.
3526 * Added connection authentication status message defined by the
3527 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3528 support for these into the code in client and server side.
3530 * Added generic function silc_client_send_command to send any command
3531 with variable argument list. Application should use this function
3532 to send commands if the command functions provided by the library
3533 does not suite for the application's user interface needs.
3535 * Added new `failure' client operation. Application is notified about
3536 received failure packet if client is executing a protocol. In this
3537 case the protocol's execution has failed.
3539 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3540 is required by the protocol.
3542 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3543 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3546 * Added status flag to SilcSKE object to indicate realtime status
3547 of the SKE protocol.
3549 * Application receives now exactly same command reply arguments as
3550 the library receives from server. However, if ID is received the
3551 corresponding ID entry is returned to the application (eg. Client
3552 ID is mapped to correct SilcClientEntry entry and that is returned).
3553 Changed command_reply client operation due to this change.
3555 * Changed all ID's in commands and in command replys as ID Payloads.
3556 Change affected both client and server side codes.
3558 All ID's sent in SILC network (with execption of ID's in SILC
3559 Packet header) are sent in ID Payload to support variable length
3562 * Server now notifies nick changes and notifies all clients on
3563 the channels about the new nickname (about the new Client ID,
3566 * Implemented CMODE command to change channel modes. Supports all
3567 channel modes defined by the protocol specs except ban and invite
3568 lists. (Also, private channel key mode is supported but support for
3569 setting private channel key in client is missing, thus, this mode
3570 has no effect on client side (except that server requires that the
3571 client uses private channel key and normal channel traffic does not
3574 Also, invite mode works per se, but INVITE command does not work
3575 yet correctly, so you can set channel as invite only channel but
3576 inviting clients to the channel does not work (it is yet to be
3577 thought what's the best way to do it).
3579 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3580 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3581 Implemented CUMODE command to change user's mode on the channel.
3582 Supports all modes defined by the protocol specs.
3584 * Added NAMES command reply to return users modes on the channel.
3586 * Removed unnecessary and slow ciphers from lib/silccrypt.
3588 * Set SO_KEEPALIVE option to connection sockets by default.
3590 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3592 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3593 redefined the Notify Payload into protocol specs.
3595 * Added silc_id_payload_parse_id to get ID directly from raw
3598 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3601 accept searching by Client ID as well.
3603 * Added support for LEAVE and SIGNOFF notify types in client library.
3605 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3606 to parse ID Payload from raw data.
3608 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Added flags parameter into silc_ske_assemble_security_properties
3611 function in lib/silcske/silcske.[ch].
3613 * Changed notify client operation to fit better for notify messages
3614 sent by server. The notify payload received from server is now
3615 passed to the application (after parsing it to SilcNotifyPayload).
3616 It is application's responsibility to retrieve the arguments
3617 from the payload and show the message the way it wants. The message
3618 sent by server is implementation specific.
3620 * Changed public keys to comply with the protocol specification.
3621 Old public keys are not supported anymore and are not compatible.
3623 * Removed nickname from Channel Payload as the latest draft removed
3624 it. The client must resolve the nickname from the NAMES command
3625 reply received when it joined the channel.
3627 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3629 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3631 * Fixed some errors in protocol specification drafts.
3633 * Created lib/silccore/silcnotify.c to implement Notify Payload
3634 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3635 generic payloads described by protocol specifications. The file
3636 includes implementations for ID Payload and Argument Payload.
3638 * Changed Command Payload implementation to use the new Argument
3639 Payload. Changed command_xxxx_payload to command_payload_xxxx
3640 to comply with SILC coding conventions.
3642 * Added suppport for Argument Payload handling in Notify Payload
3643 implementation as protocol requires it. Added the new support
3644 into server and client lib as well.
3646 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Added support for multiple nicknames on same channel. [n] is
3649 added locally to the nickname if there are more than one same
3650 nicknames on the channel.
3652 * Server now sends all nicknames that matched WHOIS request.
3653 Client also shows the list received from server.
3655 * Added TOPIC command to client side. User can now set and show
3656 current topic on channel.
3658 * Added MOTD command to client and server. Also, server sends the
3659 motd when client connects to the server.
3661 * Changed version strings to comply ISO 8601.
3663 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Fixed protocol error handling in client library. It should now
3666 cope even if the SKE fails for some reason.
3668 * Made new protocol specification drafts for submitting to IETF.
3670 * Implemented TOPIC command to server in silcd/command.c.
3672 * Added two new notify types into lib/silccore/silcnotify.h:
3673 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3674 notify nickname change and topic setting/change on a channel.
3676 * API change of command_reply operation in client library. The
3677 application gets now the status type received from server as well.
3679 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3683 * Cras fixed and optimized the packet handling even further and
3684 it should work now. Minor change to the prototype of function
3685 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3687 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3689 * Added new function into lib/silcutil/silcschedule.[ch]:
3690 silc_schedule_with_fd to select() a specified fd. The function
3691 returns after timeout expires or data arrives or goes. The
3692 function is used by packet routines to wait that all data is
3693 received from network.
3695 * Fixed data reading from network in lib/silccore/silcpacket.c.
3696 The code now assures that all data is read from the fd and then
3697 continues packet processing. This was a bug fix since the code
3698 used to drop some data in some circumstances.
3700 * Added new function into lib/silcclient/client.[ch]:
3701 silc_client_start_key_exchange to start key exchange after
3702 connection has been established to server. The code internally
3703 now uses this funtion but its main purpose was to provide it
3704 for applications that perform their own connecting. After
3705 application has created a connection it merely calls this
3706 function to start the key exchange between client and server.
3707 The library takes care of everything else after that.
3709 Updated also lib/silcclient/README to explain the usage of
3712 * Do not send to application information that connection has
3713 been established. Application gets notified it by connect
3716 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Applied cras's patch to add silc_schedule_one function. The
3719 function runs scheduler once and returns.
3721 * Fixed the scheduler after cras messed it up. The timeout
3722 handling works now as it's supposed to work.
3724 * Added into lib/silccore/ silcnotify.h to include notify
3725 message types support. Changed silc_server_send_notify*
3726 functions, in server.[ch], to support those new notify types.
3727 Added the support for the notify types into client library,
3728 as well. Added new notify client operation into ops.h in
3731 * Changed silc_server_packet_send_to_channel to send normal
3732 packets instead of just channel message packets. The function
3733 is now used to send the notify packets to channels. It is not
3734 used to send channel message packets anymore, as server never
3737 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3738 va_arg()s as it seems to require it nowadays. I guess, if SILC
3739 is compiled with older va_arg() the new code should work anyway.
3741 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3743 * Splitted core library. Core library (lib/silccore) includes
3744 now only SILC protocol specific core (and common) components.
3745 Created new utility library (lib/silcutil) that includes more
3746 generic purpose stuff. The stuff for util library was taken
3747 from the old core library. This was minor and easy split.
3749 * Created SILC Client Library (lib/silcclient) that includes
3750 implementation of the SILC client without user interface. This
3751 was major move from silc/ directory. The code has been changed
3752 so that it is transparent towards the user interface. The
3753 silc/ directory includes now the same user interface as before
3754 and it uses the new client library. Read lib/silcclient/README.
3755 Basicly, the client library performs everything else related
3756 to SILC except user interface handling. Also, configuration
3757 files are considered to be part of user interface and library
3758 does not handle them.
3760 This change also changed a lot of structures, function naming etc.
3761 Most important change was that SilcClientWindow object was
3762 renamed to SilcClientConnection in the client library. Created
3763 also new file lib/silcclient/ops.h. Also added new files
3764 silc/local_command.[ch] and silc/client_ops.[ch].
3766 All these changes were made to make it easier for user interface
3767 designers to create what ever user interface for the SILC client
3770 It is also expected that the server will be moved to lib
3771 directory as well and SILC Server Library will be created;
3772 sometimes in the future.
3774 * Removed Local commands from lib/silccore/silccommand.h as
3775 they are application specific and new client library does not
3776 handle any of those anymore.
3778 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3779 old client implementation in silc/.
3781 * Added support for callback functions in SILC_LOG_* macros.
3782 Application can now set its own callbacks that will be called
3783 instead of using the default functions that will always print
3784 the debug messages to stderr (or stdout). Also, debugging can
3785 now be disabled by setting silc_debug to FALSE and re-enabled by
3786 setting it to TRUE. Note, that logging will still work even
3787 if debugging is disabled.
3789 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3790 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3791 silc_log_reset_debug_callbacks.
3793 * To enable debugging in silc client one must give now -d
3794 option on command line.
3796 * Changed silc_schedule_init to automatically allocate task queues
3797 if they are not allocated before calling it.
3799 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * Added GMP 3.1 into math library.
3803 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3806 a channel in SILC network. The packet is used by servers and
3807 routers to notify other routers that user has left a channel.
3808 This little feature was missing until now. Added the feature
3809 to protocol specification as well.
3811 Added functions: silc_server_send_remove_channel_user and
3812 silc_server_remove_channel_user into server.[ch].
3814 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3815 lib/silccore/silcpacket.h. However, they are not implemented
3818 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Fixed joining to a channel and sending channel messages
3821 between server and router. The channel message sending should
3822 now work inside a cell.
3824 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Fixed the private message sending between server and router.
3827 The private message sending should now work inside a cell.
3829 * Added silc_server_replace_id into server.[ch] to replace
3830 existing ID in the SILC network.
3832 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3833 and silc_idlist_replace_server_id into idlist.[ch] in server.
3835 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3837 * Fixed the server to server connections. Server can again now
3838 connect to router. Router to router connections probably does
3841 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Added dynamic protocol registering support. Now protocols can
3844 registered and unregistered on the fly. Patch by cras.
3846 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3848 * Added lib/contrib directory to hold routines that some platforms
3849 don't have but are needed by SILC.
3851 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3852 into lin/contrib to provide getopt() and getopt_long() for
3853 those who don't have it.
3855 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Added AWAY command to client. When away message is set and
3858 client receives a private message packet the client automatically
3859 replies to the sender with the away message.
3861 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3862 bug seemed to be the cause of recent problems when compiling
3865 * Added version detection support to SKE protocol specification
3866 and added the new changes to the SKE implementation as well.
3867 There were other minor changes in the SKE protocol as well.
3869 Many changes in lib/silcske/silcske.[ch] and in
3870 lib/silcske/payload.[ch].
3872 * Added ^U functionality, clear input line. Patch from cras.
3874 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Mainly small bugfixes on core library. Fixed some debugging
3877 logging and buffer overflow in silclog.c.
3879 * Updated config.sub and config.guess on the distribution tree.
3881 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * Added command lagging support in server. Client may execute
3884 commands now only once in two seconds.
3886 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Optimized packet reception. MAC computation and checking is now
3889 also more optimized. A lot previously duplicated code is now
3890 used as generic by both client and server.
3892 * Fixed key pair generation in clientutil.c
3894 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3896 * Added into lib/silccore/silcbufutil.[ch] new function;
3897 silc_buffer_realloc.
3899 * Moved generic packet sending/encryption functions to
3900 lib/silccore/silcpacket.[ch] from client and server. Some
3901 rewriting of the functions.
3903 * Moved all generic packet reception/decryption functions to
3904 lib/silccore/silcpacket.[ch] from client and server. The
3905 packet processing is now much cleaner in both client and server.
3906 These were major changes in both client and server.
3908 * Created many common functions in server to do packet sending.
3909 Previously code were duplicated a lot, this has been removed
3912 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Rewrote major parts of the ID cache system. Don't know
3915 whether it is better now or not but at least the API is more
3918 * Major rewrite on ID cache stuff on client because of the ID
3919 cache API changes. Added idlist.c to client.
3921 * Also major rewrite on ID cache stuff on server as well.
3922 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3923 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3924 in hand, instead they are all put into the ID cache system now.
3925 All server_idlist_* routines uses ID cache now instead of
3926 traversing its own lists (those lists does not exist anymore).
3927 SilcIDList though still exists. Also, SilcXXXEntry's are
3930 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Finally made the SKE implementation compliant to the protocol
3933 specification. All mp integers are now binary encoded as
3934 opposed being HEX encoded.
3936 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3939 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3940 functions: silc_[encode/decode]_pem. Also added function
3941 silc_encode_pem_file to PEM encode with newlines ('\n') for
3944 * SILC public keys are now encoded either PEM or binary. Same
3945 option is for private keys as well. By default private keys
3946 are binary encoded and public keys PEM encoded. Silly HEX
3947 encoding were removed.
3949 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3950 function to create fingerprints.
3952 * Fixed a bug in SHA1; does not change the original data anymore.
3954 * Partly implemented INFO command on client and server side.
3955 Fixed CLEAR command. Changes to SERVER command; show current
3956 server(s) when giving command without arguments. Added
3957 VERSION command to client.
3959 * Added check to server that unregistered connections cannot
3960 execute commands (unless it is specificly allowed).
3962 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Fixed screen refresh.
3966 * Fixed channel joining bug from client. On some circumstances
3967 client tried to join to a channel it had already joined.
3969 * Added public key verification process into client's protocol.c.
3970 The client now verifies the public key from user and saves
3971 it into ~./silc/serverkeys/ directory.
3973 Added into: clientutil.[ch]: silc_client_verify_server_key.
3975 * Changed SKE protocol's silc_ske_initiator_finish function
3976 to accept callback function that verifies the received public
3977 key. Removed old silc_ske_verify_public_key function.
3979 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3982 silc_pkcs_private_key[_data]_set.
3984 * Made the password and public authentication more cleaner in
3985 server's protocol.c.
3987 * Removed historic and obsolete protocol `channel_auth' from
3988 both client and server.
3990 * Removed wrong way of sending command status messages from
3991 server to client in server's command.c. The old way violated
3992 protocol specification.
3994 Changes to silccore/silccommand.[ch]: removed
3995 silc_command_encode_status_payload -> not needed anymore,
3996 changed silc_command_encode_payload_va to accept extra
3997 argument on variable argument list. The argument type must
3998 now be provided to the function. Also, added new function:
3999 silc_command_encode_reply_payload_va which is same as
4000 normal command_encode_payload_va except command status type
4001 is provided as extra argument.
4003 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Added ~./silc directory handling. The directory includes the
4006 public and private keys for the client.
4008 Added silc_client_check_silc_dir, silc_client_create_identifier
4009 and silc_client_load_keys.
4011 * Implemented SILC protocol compliant public key. Added public
4012 and private key saving to and loading from files.
4014 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4015 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4016 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4017 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4018 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4020 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4021 silc_pkcs_load_[public/private]_key.
4023 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * Added silc_server_get_route (route.[ch]) to get connection
4026 data for the fastest route for given ID.
4028 * Implemented INVITE command on client and server. The command
4029 were re-defined in the SILC Protocol Specification and the
4030 implementation now complies with the specification.
4032 * Implemented PING command on client and server.
4034 * Implemented NAMES command on client and server. The server side
4035 supports currently only normal server not router server yet.
4036 Some changes to NAMES definition in SILC protocol specification.
4038 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Implemented LEAVE command on client and server.
4042 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4043 again. This change was made to the protocol as well. Server
4044 should not violate the protocol specification anymore.
4046 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4049 was tested. SOCKS4 was not but should work anyway.
