1 Mon Jun 4 14:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4 irssi/src/fe-text/gui-window.c.
6 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
7 to in-active server. The affected file is
8 irssi/src/silc/core/client_ops.c.
10 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
12 * Changed the protocol API a bit more consistent in the
13 lib/silccore/silcprotocol.[ch].
15 * Changed the following headers to ROBODoc format:
17 lib/silccore/silcpayload.h
18 lib/silccore/silcprotocol.h
19 lib/silccore/silcsockconn.h
21 All core library headers are now formatted.
23 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
25 * Fixed a bug in Irssi SILC client; do not show that you are
26 server/router operator if you really are not. Affected file is
27 irssi/src/silc/core/client_ops.c.
29 * Renamed silc_command_free_payload to silc_command_payload_free.
30 Affected file lib/silccore/silccommand.h
32 * Added silcmath.h to include the prototoypes of various routines
33 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
36 * Changed the following headers to ROBODoc format:
38 lib/silccore/silcchannel.h
39 lib/silccore/silccommand.h
41 lib/silccore/silcidcache.h
42 lib/silccore/silcmode.h
43 lib/silccore/silcnotify.h
44 lib/silccore/silcpacket.h
45 lib/silcmath/silcmath.h
47 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
49 * Added checking to the server code not to start the server if
50 ciphers and stuff are not configured properly. Affected files
51 silcd/serverconfig.[h] and silcd/server.c.
53 * Changed the layout of the header files of the public interfaces
54 in the SILC libraries. The new layout supports ROBODoc
55 documentation tool (and some others) so that it is easy to create
56 a library reference manual. All the other headers and source
57 code must still follow the CodingStyle document. Also source
58 code must not include these ROBODoc stuffs, only the headers.
59 Furthermore, all public interface headers must now be named
60 by using `silc' prefix, example: silcapi.h, silccipher.h.
61 Some files were renamed due to this. All the other headers
62 must not be used as public interfaces. I will update the
63 CodingStyle document later. Changed following headers, so far:
65 lib/silcclient/silcapi.h
66 lib/silccore/silcauth.h
67 lib/silccore/silcprivate.h
68 lib/silccrypt/silcdh.h
70 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
74 * Removed silc_client_packet_send_flush from the client library
75 as it is not needed. Affected file lib/silcclient/client.[ch].
77 * Added printing of message of unresolved authentication method
78 to the Irssi SILC client. Added it to the module formats.
79 Removed the same message from the client library.
81 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
83 * Added new distribution feature, DISTLABEL. Every distribution
84 can define own preprocessor label that can be used in the
85 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
86 file distributions, acconfig.h.pre and prepare.
88 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
90 * Added Makefile.defines_int to include the actual definitions
91 for Makefile.defines.in. Tested the new distribution system,
92 created distributions and tested installation.
94 * Added AWAY message printing to the Irssi SILC client. Added
95 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
97 * Added SCONNECT command to call the SILC's CONNECT command.
98 Cannot use CONNECT directly since Irssi uses that internally.
99 Affected file irssi/src/silc/core/silc-servers.c.
101 Added ACTION local command. It is same as ME command but takes
102 the channel as mandatory argument.
104 Rewrote some of the Irssi's help files to suite for SILC
107 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Added Makefile.defines[.in] that should for now on be included
110 in all Makefile.am file in the source tree. That file includes
111 all common compilation definitions for SILC source tree.
113 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
115 * Minor changes to the ./prepare script to change the package
116 name according the distribution name to the configure.in.
118 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
120 * Created new distribution system. Added file `distributions'
121 that defines all the distributions that can be created out of
122 the SILC source tree. The ./prepare script now reads that
123 file to determine how to prepare the distributions. The
124 first argument to the ./prepare is the name of the distribution
125 and second is the version of the distribution. If given
126 without arguments it creates the default (toolkit) distribution
127 with the default version (defined in ./prepare).
129 All Makefile.am files that are subject to the distributions
130 are now named as Makefile.am.pre. These are ./Makefile.am
131 and lib/Makefile.am. Others may be changed later.
133 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
135 * Added invite list, ban list, some key management and connection
136 error message printing to module formats in the Irssi SILC client.
138 * Added new silc_client_set_away_message to set the away message
139 that is back to the person who sent private message. The
140 affected file lib/silcclient/silcapi.h and the
141 lib/silcclient/client_prvmsg.c.
143 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
145 * Fixed the private message sending in the Irssi SILC client,
146 added local command KEY to the Irssi SILC client.
148 Added key management and key agreement message formats to the
149 irssi/src/fe-common/silc/module-formats.[ch].
151 Added USERS (alias WHO) printing, server/router operator
152 indication and LIST command printing to the module formats.
154 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
156 * Fixed channel joining notify handling, cumode notify handling
157 from Irssi SILC client.
159 * Added SILC specific module-formats to the Irssi SILC client so
160 that SILC specific message hilighting, colors etc is possible.
161 Affected file irssi/src/fe-common/silc/module-formats.[ch].
163 Added channel mode, channel user mode, actions, notices,
164 whois and whowas printing to the the module-formats.c.
166 * Fixed a bug in channel deletion in the server. The channel
167 is not left to the cache even if the channel founder auth mode
168 is set when there are no users anymore on the channel. Affected
171 * The silc_net_localhost now resolves the entire hostname including
172 the domain name. Affected file lib/silcutil/silcnet.c.
174 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
176 * Changed the ask_passphrase client operation to be ascynchronous.
177 It has now a completion callback and a context that the
178 application must call after it has got the passphrase from
179 the user. Affected files lib/silcclient/silcapi.h,
180 lib/silcclient/protocol.c, lib/silcclient/command.c and
183 Added SilcAskPassphrase callback that the application calls
184 to deliver the passphrase to the library.
186 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
187 The public key verification and especially a certificate
188 verification is asynchronous procedure.
190 Added new SILC_SKE_STATUS_PENDING status to indicate the
191 request is pending and a callback will be called to finalize
194 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
195 indicate that remote end did not send its public key (or
196 certificate), even though we require it. Added check for this
197 condition in the SKE. This was a security bug, now fixed.
199 Defined new SilcSKEVerifyCbCompletion callback that is called
200 when the verification process is completed.
202 The affected files lib/silcske/silcske_status.h and
203 lib/silcske/silcske.[ch].
205 * Changed the verify_public_key client operation to be async
206 as well. Defined SilcVerifyPublicKey callback that is used to
207 indicate the success of the public key verification process.
209 Changed the server and client to use the new async client
212 * Changed the Irssi SILC client's internal scheduler to be called
213 twice as many times as it used to be. As a result the client
214 should be a bit faster now. Affected file is
215 irssi/src/silc/core/silc-core.c.
217 * Added support to Irssi SILC client of asynchronous public key
218 verification and passphrase inquiry. Affected file is
219 irssi/src/silc/core/silc-core.c.
221 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
223 * Do not say "You have left channel %s" in client library.
224 Moved it to the application. Affected files are
225 lib/silcclient/command.c and silc/client_ops.c.
227 * Fixed silc_client_get_clients. Command context was not
228 duplicated and was freed memory in the callback. Affected
229 file lib/silcclient/idlist.c.
231 * Do not say "you are now talking..." on JOIN command in the
232 client library. The appliation must handle it.
234 * Do not say ".. changed topic to" in command reply in the
235 client libary. The application must handle it.
237 * Fixed TOPIC command sending in the client library.
239 * Fixed a memory leak in silc_client_command_free in the file
240 lib/silcclient/command.c.
242 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
244 * Imported a modified version of Irssi client to the source tree.
245 The Irssi will be used to create a new client called
246 Irssi SILC. Imported to irssi/.
248 Added silc_core_init_finish function to the Irssi. Affected
249 file irssi/configure.in.
251 A lot changes in the Makefile.ams around the irssi tree.
253 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
255 * Do not rehash if the new size is same as the old size of the
256 hash table, in the silc_hash_table_rehash*. The affected file
257 lib/silcutil/silchashtable.c.
259 * Replaced hash_table_del_by_context calls from the server
260 (when channel->user_list and client->channels) to the
261 hash_table_del as it is sufficient and faster.
263 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
265 * Added silc_hash_table_list, silc_hash_table_get and the
266 SilcHashTableList structure to provide an alternative way to
267 traverse the hash table. The affected files are
268 lib/silcutil/silchashtable.[ch].
270 * Changed the server's idlist routines to use the hash table
271 routines to optimize the code.
273 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
275 * Replaced the client entry's `channel' list and channel entry's
276 `user_list' list to hash tables for optimized lookup. Changed
277 the code to use the hash table interface around the code.
278 Affected file lib/silcd/idlist.[ch].
280 * Added `auto_rehash' boolean argument to the function
281 silc_hash_table_alloc to indicate whether the hash table should
282 auto-rehash when it thinks is appropriate time. It will
283 increase the hash table size if the there is twice as much
284 entries in the table than the size of the table, and will
285 decrease the size if there are twice as less entries than
286 the size of the table.
288 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
290 * Fixed silc_xxx_get_supported to not crash at some circumstances.
292 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
294 * silc_idcache_purge_by_context deletes the entry now by context
295 as it is supposed to do. Affected file lib/silccore/idcache.c.
297 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
298 client is not anymore valid (WHOWAS givens the info) and not
299 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
301 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
303 * Removed the `data' and `data_len' arguments from the ID Cache
304 interfaces and added `name' argument. ID Cache does not handle
305 anymore the binary data only a names associated with given ID.
307 * When hashing a Client ID with silc_hash_id the entire ID is
308 not hashed anymore, instead only the hash of the Client ID is
309 hashed. This way we can access the Client ID from the cache
310 with Client ID but with the hash of the ID (which is a hash of
311 the nickname) as well without any difference in performance.
313 Added also silc_idcache_find_by_id_one_ext to do one on one
314 searching when we have the actual ID. Added also function
315 silc_hash_client_id_compare. The affected files are
316 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
318 * When hashing the name associated with a ID it is always done
319 in lowercase. This way we can access the cache without worrying
320 about case-sensitivity, even though, for example nicknames are
323 * Fixed a bug in server with channel message sending. It put
324 wrong ID type as destination ID. The affected file
327 * silc_idcache_del_by_context now deletes from all hash tables
328 by context. Affected file lib/silccore/idcache.c.
330 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
332 * Changed the client library to use the new ID Cache interface.
333 Changes around the source tree.
335 * Added silc_hash_table_rehash_ext to rehash with specific
336 hash function. Affected file lib/silcutil/silchashtable.[ch].
338 * Added silc_hash_string_compare to compare two strings in the
339 hash table. Affected file lib/silcutil/silcutil.[ch].
341 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
343 * Added new function silc_idcache_del_by_context into the
344 lib/silccore/idcache.[ch].
346 * Changed the server's ID list routines to use the new ID Cache
347 interface. Changes around the source tree.
349 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
351 * Added silc_hash_table_del[_by_context]_ext functions in to the
352 lib/silcutil/silchashtable.[ch].
354 Removed silc_hash_table_find_all* routines and added new
355 silc_hash_table_find_foreach to replace them.
357 Added silc_hash_table_replace_ext function as extended
358 replacing function. Separated the simple hash table interface
359 from the extended hash table interface in the file
360 lib/silcutil/silchashtable.h.
362 * Fixed minor bugs and changed it to use some of the new
363 hash table functions in lib/silccore/idcache.c
365 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
367 * Added new function silc_hash_table_find_all to return all keys
368 in the hash table by the specified key. As the hash table is
369 collision resistant it also makes it possible to have several
370 duplicate keys in the hash table. This function may be used to
371 find all of the keys from the hash.
373 Added user_context arguments to the SilcHashFunction,
374 SilcHashCompare and SilcHashDestructor to deliver user specified
377 Added new fuctions silc_hash_table_find[_all]_ext to do
378 extended lookup with specified hash and compare functions and
379 specified user contexts.
381 Added new function silc_hash_table_add_ext to add the key
382 with specified hash function and user context.
384 Added new function silc_hash_table_foreach to traverse all
385 entrys in the hash table. Added SilcHashForeach callback
388 Added new function silc_hash_table_del_by_context to delete
389 the entry only if the context associated with the key matches.
391 Affected files are lib/silcutil/silchashtable.[ch].
393 * Removed silc_hash_[server/client/channel]_id and added just
394 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
395 silc_hash_id_compare to compare two ID's using as the hash table
396 comparison function. Added also silc_hash_data to hash
397 binary data and silc_hash_data_compare to compare it.
399 * Removed silc_idlist_find_client_by_hash as it is not needed
400 anymore. Affected file silcd/idlist.[ch].
402 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
403 to use internally the SilcHashTable. The new ID Cache is a lot
404 faster than the old one. Some of the ID Cache interface was also
405 rewritten and obsolete and stupid functions were removed.
407 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
409 * Added entry_count field to the SilcHashTable to keep the number
410 of the entries in the table. Implemented the function
411 silc_hash_table_rehash. Added new function
412 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
414 Fixed a minor bug in silc_hash_table_free.
416 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
417 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
418 into the lib/silcutil/silcutil.[ch].
420 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
422 * Implemented a collision resistant hash table into the
423 lib/silcutil/silchashtable[ch]. See the header and the source
424 for the SilcHashTable API.
426 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
428 * Merged dotconf version 1.0.2 into lib/dotconf.
430 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
432 * Do not compile anything in lib/silcsim/* if the SIM support
433 is not enabled. The tree should now compile without problems
436 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
438 * Compiled the SILC under cygwin. Compiled and tested briefly
439 without problems. More tests needed. The SIMs didn't compile
442 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
444 * Fixed possible crash in silc_get_username in the
445 lib/silcutil/silcutil.c.
447 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
449 * Fixed a va_arg in silc/client_ops.c.
451 * Oops, RC5 routines were named AES and caused some problems
452 when not using SIM's. Affected file lib/silccrypt/rc5.c.
454 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * Added new SilcIDIP structure into the lib/silccore/id.h and
457 replaced the old `ip' fields from all SILC ID's to that type.
458 This is a step towards IPv6 support.
460 The silc_id_get_len takes now the ID as an extra argument.
461 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
462 both IPv4 and IPv6 based ID's.
464 The affected files are lib/silccore/id.[ch] and other files
465 around the tree using these routines.
467 * Removed the ID length arguments in server from various
468 silc_server_send_notify_* routines -> they are not needed
471 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
473 * Fixed memory leak in silc_encode_pem_file in the file
474 lib/silcutil/silcutil.c.
476 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
478 * Check minor version as well in the SKE. Affected files are
479 silcd/protocol.c and lib/silcclient/protocol.c.
481 * Added --identifier option to the server so that an identifier
482 can be when creating the public key for the server. Affected
483 file is silcd/silcd.c.
485 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
486 lib/silccrypt/silcpkcs.c.
488 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
490 * Register default ciphers and stuff when using -C option with
491 the server. Affected file sildc/silcd.c.
493 * Put back the servers public key filename format, it is better
494 than the new one. For now, the client keys are saved with the
495 new filename format. The affected file silc/client_ops.c.
497 * Implemented the Cipher API for the rest of the ciphers that
498 did not implement it or implemented it the wrong way.
500 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
502 * Register default ciphers and stuff when using the -S option
503 in the client. Affected file silc/silc.c. Same also when
504 creating new key pair with -C option.
506 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
508 * Fixed the silc_verify_public_key client operation function to
509 save the public keys differently. The fingerprint is now
510 used as filename and not the hostname. This way also the
511 client keys are saved uniquely and not with hostnames. The
512 affected file is silc/client_ops.c.
514 * Trimmed the silc_hash_fingerprint function to remove extra
515 whitespaces from the end of the fingerprint. The affected
516 file is lib/silccrypt/silchash.c.
520 * Added silc_cipher_register_default function to register all
521 default ciphers. It can be used when configuration files
522 does not exist and the application does not want any specific
523 ciphers in any specific order.
525 The SilcDList is now used as silc_cipher_list dynamically
526 allocated cipher list. Removed the static list all together
527 and now all ciphers must be allocated to the dynamic list.
528 The silc_cipher_alloc routine was changed to check only the
531 All silc_cipher_* routines that used to return int returns
534 The affected files lib/silccrypt/silccrypt.[ch].
536 * The same thing was done to silc_hash_* as for silc_cipher_*
537 routines. Affected files lib/silccrypt/silchash.[ch].
539 * The same thing was done to silc_pkcs_* as for silc_cipher_*
540 routines. Affected files lib/silccrypt/silcpkcs.[ch].
541 Added also silc_pkcs_[un]register[_default] functions.
542 Removed the data_context from the PKCS API.
544 * Added silc_hmac_register_default function to register default
545 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
546 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
547 to unregister all hmacs at once.
549 * Register the default ciphers, hash functions, PKCSs and HMACs
550 if client's configuration file does not exist. The affected
553 * The client did not load the hash functions from the SIM
554 modules at all. Added support for this. Affected file is
557 * When decoding public key with silc_pkcs_public_key_decode, check
558 the supported algorithm only if PKCS are registered. Affected
559 file lib/silccrypt/silcpkcs.c. The same was done with the
560 silc_pkcs_private_key_decode.
562 * Fixed the SILC List routines to keep the list always in order.
563 It used to change the list's order when traversing the list but
564 not it preserves the order. Affected file lib/trq/silclist.h.
566 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
568 * Added the client library to use the SilcSocketConnection's
569 reference counter (by silc_socket_dup) to prevent the bug that
570 the socket object may be freed underneath async operation.
572 * The name resolv library checking fixes in the configure.in.pre.
575 * Created new version of the protocol drafts for future
576 development. The -03 drafts are the ones that will be changed
577 in the trunk now and the -02 will remain as they are.
579 * Send list of CUMODE notifys to the router when announcing
580 the channel users to the router. Affected file silcd/server.c.
581 If the router receiving channel founder CUMODE for a channel
582 that already has channel founder it will send CUMODE notify
583 to the sender to remove the channel founder rights from the
584 announced client. Affected file silcd/packet_receive.c.
586 * The CUMODE notify may now use Server ID as well as the entity
587 who changes the mode. Updated protocool specs.
589 * Updated INSTALL and README files.
591 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
593 * New web pages in the http://silc.pspt.fi. The pages was
598 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
600 * Implemented the [DenyConnectin] config section in the server.
601 Added silc_server_config_denied_conn to check whether incoming
602 connection is denied. Affected file silcd/serverconfig.[ch].
604 * Do not check the ports when checking the incoming configuration
605 data if the port is 0, meaning any. Affected file is
606 silcd/serverconfig.c.
608 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
610 * Fixed buffer overflow in silc_string_compare in the file
611 lib/silcutil/silcutil.c.
613 * Fixed double free in silc_server_command_leave in the file
616 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * Fixed the version checking in the server. Affected file is
621 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Fixed the configuration data fetching when accepting new
624 connections in the server. Affected file silcd/server.c.
626 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Added `sender_entry' argument to the function
629 silc_server_packet_relay_to_channel so that we can check
630 whether some destination actually belongs to the same route
631 the sender belongs (ie, we must not resend the packet to the
632 sender). Affected file silcd/packet_send.[ch].
634 * Added `servername' field to the SilcClientEntry in the server
635 to hold the name of the server where client is from. Affected
636 file is silcd/idlist.h.
638 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Moved the channel message encrypting in the router betwen
641 router connections from silc_server_channel_message to the
642 silc_server_packet_relay_to_channel since we want to check
643 whether we have anybody channel before encrypting anything.
644 Affected files silcd/packet_[receive/send].c.
646 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
648 * Fixed the [AdminConnection] server config section to support
649 multiple entries. Affected file silcd/serverconfig.c.
651 * Added support into the server to check the validity of the
652 incoming connection before executing any KE or authentication
655 * The connection configuration is now saved to the KE and
656 connection auth protocol contexts and not fetched anymore in
657 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
659 * The local hosts listenning address and port is also resolved
660 now when starting the server. We want to have the socket object
661 to include the real address and port for the listener. Added
662 new function silc_net_check_local_by_sock into the files
663 lib/silcutil/silcnet.[ch].
665 * Fixed a broadcast bug in server -> do not broadcast if we
668 * Fixed a routing bug. Do not route broadcast packets ever.
669 Broadcast packets must be processed always and not routed since
670 they may be destined to some other host than yourself and thus
671 would get routed without no good reason. Affected file is
674 * Added function silc_server_config_is_primary_route to check
675 whether primary router connection has been configured (a router
676 configuration that we are initiating). If there is not, we
677 will assume that there is only two routers in the SILC network
678 and we will use the incoming router connection as our primary
679 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
681 * Changed the order of the broadcasting. Broadcast _after_ the
682 packet has been processed not before. Affected file is
685 * Fixed a [ClientConnection] parsing bug. The port was never
686 parsed correctly thus resulting to port 0. Affected file
687 silcd/serverconfig.c.
689 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
690 argument and did not set the broadcast packet flag. Affected
691 file silcd/packet_send.c. Fixed same bug in the function
692 silc_server_send_notify as well.
694 * If we receive NEW_ID packet for our own ID in the server, ignore
697 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * Removed the nickname from the Private Message Payload.
702 Updated the code and the protocol specs.
704 * Updated protocol specs for submitting to the IETF.
706 * Tweaked the Random Number Generator a bit. Affected file
707 lib/silccrypt/silcrng.c. Exported a new function
708 silc_rng_[global]_add_noise which can be used to add more
711 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
713 * Do not parse packets with different timeout when protocol
714 is active -> may cause problem with rekey. Affected file
717 * When server receives signoff notify it must not create
718 new channel key if the client is on any channels since the
719 sender of the signoff notify will create it.
721 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
723 * Added printing of error messages during SKE protocol from the
724 failure packet sent by server during SKE. Affected file
727 * Removed the client's failure_callback handling with timeout
728 and handle it immediately when received.
730 * The SKE library returned wrong type in SUCCESS and FAILURE
731 packets. They must be 32 bit MSB not 16 bit MSB.
733 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
735 * Ok, rewrote the logic of the re-key and now it seems to work.
736 I tested it on high traffic with frequent re-keys without
737 problems. Added hmac_receive (and renamed hmac to hmac_send)
738 in SilcClientConnection in lib/silcclient/client.h and
739 in SilcIDListData in silcd/idlist.h. Also, removed the
740 SilcPacketParserContext's cipher and hmac fields as they are
741 not needed anymore and actually caused some problems when
742 the ciphers and hmac's changed underneath the packet parser.
744 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
746 * If re-key protocol is active then process the incoming packets
747 synchronously since we must assure that icoming packets encrypted
748 with the old key is processed before the new keys is set to
749 use. This is true other packets than for REKEY packets.
750 Affected file silcd/server.c. The same was done to client library
751 as well, affected file lib/silcclient/client.c.
753 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * Fixed bug in client and server to accept the force send if
756 the packet is send from silc_[server/client]_packet_process
757 function. Otherwise the packets are never delivered, oops.
759 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Disable force sending of packets when REKEY protocol is active.
762 We must assure that no packet is sent directly when rekey is
763 performed. All packets must be sent through packet queue.
764 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
765 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
766 function is silc_[server/client]_packet_send_real to check
769 * Replaced the SIM paths from example config files to
770 /usr/local/modules. Also, make install creates now
771 /usr/local/silc/logs directory to hold all the SILC server
774 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * Made the configure.in.pre work on Solaris. Patch by salo.
778 * Made all ciphers compatible with non-x86 machines. Defined
779 CBC mode macros into lib/silccrypt/ciphers_def.h.
781 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
783 * Fixed the make install.
785 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * When MAC computation fails the silc_packet_decrypt returned 0
788 even though it was supposed to return -1. Fixed this. The
789 affected file is lib/silccore/silcpacket.c.
791 * Do not replace the config files in /etc/silc (in make install)
792 if they already exist. Affected file ./Makefile.am.
794 * Do not send re-key packets immediately but through packet queue.
795 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
797 * Changed silc_net_check_host_by_sock to return FALSE if the
798 IP/DNS could not be resolved. Though, it returns the IP address
799 now even if it could not resolve it (but returns also FALSE).
800 Affected file lib/silcutil/silcnet.[ch].
802 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
804 * Added silc_pkcs_decode_identifier to decode the public key's
805 identifier. Affected file lib/silccrypt/silpkcs.[ch].
806 Added also silc_pkcs_free_identifier. Added also new context
807 SilcPublicKeyIdentifier.
809 * Added -S option to the silc client. It is used to dump the
810 contents of the specified public key file.
812 * Changed the PKCS api to return the public key length when
813 setting the public key.
815 * Fixed a fatal bug in the public and private key file loading.
816 Affected file lib/silccrypt/silcpkcs.c.
818 * Execute the packet parsing for client with zero (0) timeout
819 if the protocol is active. Affected file silcd/server.c.
821 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
823 * Made the key generation options to the silcd program. Added
824 -C option, equivalent to client's option.
826 * Added new [ServerKeys] config section to the server. It
827 configures the server's public and private key.
829 * Defined generic Public Key Payload into the protocol
830 specification to send specific type of public keys and
833 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
834 public key or certificate.
836 * Implemented the GETKEY command to the server and to the
837 client library and on user interface.
839 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
841 * Made preliminary `make install' work.
843 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
845 * Added SilcServerRekey context into silcd/idlist.h.
847 * Added the PFS support as defined in the specification to the
848 SKE protocol. Affected files lib/silcske/*.c.
850 * Added `ske_group' field to the SilcServerRekey context to hold
851 the number of the SKE group that is used with PFS in re-key.
852 Affected file silcd/idlist.h.
854 * Added PFS re-key support to the server. Affected file is
857 * Added silc_protocol_cancel to cancel execution of the next
858 state of the protocol. Affected file is
859 lib/silccore/silcprotocol.[ch].
861 * Added the re-key support with and without PFS to the client
862 library. Re-key is performed once in an hour, by default.
864 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
865 Added silc_client_rekey_callback and silc_client_rekey_final.
866 Affected files are lib/silcclient/protocol.[ch] and
867 lib/silcclient/client.[ch].
869 * Removed the `hmac_key' and `hmac_key_len' fields from the
870 SilcClientConnection structure; not needed. Affected file is
871 lib/silcclient/client.h.
875 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
877 * Do not ask whether user wants to use the negotiated private key
878 for private messages, just use it. Affected file is
879 silc/local_command.c.
881 * Added `send_enc_key' and `enc_key_len' fields to the
882 SilcIDListData structure since they are needed in the re-key
883 phase. Affected file is silcd/idlist.[ch].
885 * Implemented the simple re-key protocol into the server.
886 Affected files silcd/server.c and silcd/protocol.[ch]. The
887 re-key will be performed once in an hour, by default.
889 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
890 Added silc_server_rekey, silc_server_rekey_callback and
891 silc_server_rekey_final.
893 * Removed Tunneled flag from the protocol. Updated the code
894 and the specifications.
896 * Adde `pfs' field to the SilcIDListData to indicate whether
897 the PFS is to be performed in the re-key. Affected file is
900 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
902 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
903 int64 of at least the xintXX size. If void * is less that 4
904 bytes uint32 * will be used. Defined bool as boolean.
906 * Changed _ALL_ unsigned long and unsigned int to uint32,
907 unsgined short to uint16 in the source tree.
909 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
910 not handle clients that has entry->data.registered == FALSE.
911 They are not in the network anymore. Affected file is
914 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Implemented the sending of the SERVER_SIGNOFF notify in the
917 server. Affected file is silcd/server.c.
919 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
920 Added also silc_notify_payload_encode_args into the
921 lib/silccore/silcnotify.[ch].
923 * Implemented ther SERVER_SIGNOFF notify handling in the server.
924 Affected file silcd/packet_receive.c.
926 * Implemented the SERVER_SIGNOFF notify handling in the client
927 library. Affected file lib/silcclient/client_notify.c. Also,
928 implemnted the printing of the SERVER_SIGNOFF info to the
929 application. Affected file silc/client_ops.c.
931 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
932 if the deleting was successful. Affected file silcd/idlist.[ch].
934 * Added support for public key authentication in the connection
935 authentication protocol in the client library. Affected file
936 lib/silcclient/protocol.c.
938 * Changed the server's silc_idlist_get_clients_by_* interface
939 to support already allocated array so that new entries may be
940 added to pre-allocated array. Affected file silcd/idlist.[ch].
941 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
944 * All command reply functions in the server now calls the
945 pending command callback even if error occured. This way the
946 error will be delivered to the client as well. Affected files
947 silcd/command.c and silcd/command_reply.c.
949 * Fixed INFO command to return local server's info if no server
950 was provided. Affected file lib/silcclient/command.c.
952 * Removed RESTART command for good. Updated the code and the
955 * Rewrote parts of the task system. It is a bit simpler now.
956 Removed unsued task priorities. The affected files are
957 lib/silcutil/silctask.[ch].
959 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
961 * Moved the USERS printing from the library to the application.
962 Affected files lib/silcclient/command.c and silc/client_ops.c.
964 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
968 * Added channel key re-key support. The re-key is perfomed
969 only by the router and is done once in an hour. Added `rekey'
970 field to the SilcChannelEntry in the server. Affected files
971 silcd/server.c and silcd/idlist.h.
973 * Added silc_task_unregister_by_context into the file
974 lib/silcutil/silctask.[ch].
976 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
978 * Added SILC_UMODE_GONE mode to indicate when the client is not
979 present in the SILC network. Added also support to the local
980 command AWAY that will set this mode. Added support of showing
981 "xxx is gone" in WHOIS command. The USERS command shows the
984 * Fixed setting server and router operator privileges in the
985 server's UMODE command. Affected file silcd/command.c.
987 * Merged the SKE KE1 and KE2 payloads into one payload. The
988 new KE payload is equivalent to the old KE2 payload.
990 Cleaned up the SKE Start Payload parsing. It now uses the
991 simple buffer unformatting to do the parsing. A lot faster
994 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
995 to the SKE that is used to indicate whether both of the SKE
996 parties should perform authentication. By default only the
997 responder performs authentication. By setting this flag also
998 the initiator must do authentication. By default it is unset
999 since in normal SKE case, client to server connection, only
1000 the responder should do authentication. When doing SKE between
1001 two clients both should perform authentication. Updated the
1002 code and the protocol specs.
1004 * A little fix to IDENTIFY command in the server. Search the
1005 client first by hash not nickname. Affected file is
1008 * Fixed the silc_client_close_connection to support closing
1009 the client to client connections wihtout deleting too much
1010 data. Affected file lib/silcclient/client.c.
1012 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1013 are received if protocol used to be active but is not anymore
1014 the application would crash due to NULL pointer dereference.
1015 Affected files silcd/server.c and lib/silcclient/client.c.
1017 * Added `hash' field to the SilcClientConnection to include
1018 the hash function negotiated in the SKE protocol.
1020 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1021 to set the channel founder authentication data. A client can
1022 claim the founder rights later by providing the authentication
1023 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1024 This way the channel founder can regain the channel founder
1025 privileges even it is left the channel. This works only on
1026 local server and the client must be connected to the same
1027 server to be able to regain the founder rights. Updated the
1028 protocol specs accordingly.
1030 Added support to the CMODE command in the client to set the
1031 founder auth data. Read the README to see how to set it.
1033 Added support to the CUMODE command to claim the founder
1034 rights. Read the README to see how to do it.
1036 Added support for the founder authentication to the Channel
1037 Entry in the server. Affected file silcd/idlist.h.
1039 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1040 server's CMODE command. Affected file silcd/command.c.
1042 * Added the following new functions into lib/silccore/silcauth.[ch]:
1043 silc_auth_get_method and silc_auth_get_data.
1045 * The server now saves the remote hosts public key to the
1046 SilcIDListData pointer. Affected file silcd/protocol.c.
1048 * The normal server now does not remove the channel entry from
1049 the cache if the founder authentication data is set. It used
1050 to remove it if the founder was the last one on the channel on
1051 the server and left the channel. The auth data is saved and
1052 if the channel is re-joined later the old entry is used with
1053 the old auth data. Affected files silcd/command_reply.c and
1056 * Removed the `pkcs' field from the SilcIDListData structure
1057 in the server; it is not used. Affected file silcd/idlist.h.
1059 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1061 * Fixed packet processing on slow links. Partial packets were
1062 never re-processed because the incoming data buffer was cleared
1063 by the application. Application must not directly clear the
1064 sock->inbuf, the packet processing routines handle it. Fixed
1065 this in client library and in server.
1067 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1069 * Fixed the WHOIS and IDENTIFY send reply function to really
1070 check whether to send list or just one entry. Affected file
1073 * Cleaned up the LEAVE command's channel key distribution. The
1074 affected file silcd/command.c.
1076 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1077 can enforce the channel mode as well. In that case the ID
1078 includes the ID of the server. The code now enforces the
1079 mode change if the router have different mode than the server.
1081 * The notify client operation with CMODE_CHANGE notify can now
1082 return NULL client_entry pointer if the CMODE was not changed
1083 by client. Application must check for this.
1085 * Added <Server ID> argument to INFO command to support server
1086 info fetching by Server ID.
1088 * Added silc_server_announce_get_channel_users to get assembled
1089 packets of channel users of the specified channel. Affected
1090 file silcd/server.[ch].
1092 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1093 was freed underneath the ID Cache.
1095 * Re-announce clients when the server received CHANNEL_CHANGE
1096 notify from the router. Affected file silcd/packet_send.c.
1098 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1101 crashed since it did not handle the fact that there is no cipher
1102 called "3" and didn't check the error condition. Now fixed.
1104 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1105 flag. It can be used to send message requests.
1107 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * Implemented the RESTART command in the client.
1111 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1112 notice type messages. Added notice printing to the user
1115 * The channel keys are not re-generated if the channel's mode
1116 is PRIVKEY, ie private key on the channel exists. Affected
1117 files silcd/server.c and silcd/command.c.
1119 * Fixed a little bug in channel message delivery when channel
1120 private keys are set in the server. Affected file is
1121 silcd/packet_send.c.
1123 * Changed the setting on channel->on_channel = TRUE from the
1124 silc_client_save_channel_key to the JOIN command reply. The
1125 key payload is not received if the private channel key is set.
1126 Affected file lib/silcclient/command_reply.c and the
1127 lib/silcclient/client_channel.c.
1129 * When the CMODE_CHANGE notify is sent and the channel private
1130 key mode is removed the channel key must be re-generated in
1131 other cells as well. Added this support for the router in the
1132 silcd/packet_receive.c.
1134 * Added new local command NOTICE to send notice message on
1135 channel. Affected file silc/local_command.[ch].
1137 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1139 * Added new local command ME to the client. It is used to send
1140 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1141 some action. Affected file silc/local_command.[ch].
1143 * Changed channel_message and private_message client operations
1144 to deliver the message flags to the application. Added also
1145 the `flags' arguments to the silc_client_send_channel_message
1146 and silc_client_send_private_message functions. Affected file
1149 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1151 * Redefined the Private Message Payload to support private message
1152 keys and to support the new private message flags. Updated
1153 the protocol specs. Flags makes it possible to have for example
1154 CTCP style messages.
1156 * Added new type SilcPrivateMessagePayload and defined an API
1157 for it in the lib/silcclient/silcprivate.[ch].
1159 * Tested private message private keys successfully. Tested the
1160 private message key set, unset and list commands with the new
1163 * Redefined the Channel Message Payload to include the channel
1164 message flags (equal with private message flags) to support
1165 for example CTCP style messages.
1167 * Defined some of the message (for channel and private message)
1168 flags. Updated the protocol specs and added the flags to the
1169 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1171 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1173 * Added SilcKeyAgreementStatus type to the key agreement routines
1174 to indicate the current status and error if one occured.
1175 The status types are defined in the lib/silcclient/silcapi.h.
1177 * Added new local command KEY that is used to set and unset private
1178 keys for channels, set and unset private keys for private messages
1179 with remote clients and to send key agreement requests and
1180 negotiate the key agreement protocol with remote client. The
1181 key agreement is supported only to negotiate private message keys,
1182 it currently cannot be used to negotiate private keys for channels,
1183 as it is not convenient for that purpose.
1185 * Fixed a minor pending callback setting bug in the function
1186 silc_client_get_client_by_id_resolve, now the function works.
1187 Affected file lib/silcclient/idlist.c.
1189 * Added function silc_net_get_local_port to get local bound
1190 port by socket. Added to lib/silcutil/silcnet.[ch].
1192 * Added `sockets' and `sockets_count' fields to the SilcClient
1193 object. They hold the sockets of the listenning sockets in
1194 the client. Listenning sockets may be for example the key
1195 agreement server. Affected file lib/silcclient/client.[ch].
1196 Added functions the silc_client_add_socket and the
1197 silc_client_del_socket. They are exported to the application
1200 * Added ~./silc/clientkeys to support other client's public keys.
1202 * Renamed verify_server_key client operation to verify_public_key
1203 and added one argument to indicate the type of the connection
1204 (server, client etc.).
1206 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1208 * Added silc_server_connection_auth_request to handle the
1209 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1210 silcd/packet_receive.[ch].
1212 * Added silc_server_send_connection_auth_request into the
1213 silcd/packet_send.c to send the connection auth request packet.
1215 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1218 * Fixed the public key authentication in responder side in the
1219 server. The `auth_data' pointer includes the SilcPublicKey
1220 not the path to the public key. Affected file silcd/protocol.c.
1222 * Implemented the public key authentication in the initiator side
1223 in the server. Affected file silcd/protocol.c.
1225 * Removed the [RedirectClient] config section from the server
1226 configuration. Is not needed and I don't want to implement it.
1228 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Cleaned up the CMODE command in the server. It now works
1231 correctly and supports all the modes defined in the protocol.
1232 Affected file is silcd/command.c.
1234 * Added `hmac_name' field to the SilcChannelEntry in the server
1235 to hold the default HMAC of the channel. It can be set when
1236 creating the channel (with JOIN command). Affected files
1239 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1240 type to indicate the change of the current cipher and hmac
1241 on the channel. Client can safely ignore the <cipher> argument
1242 (if it chooses to do so) since the CHANNEL_KEY packet will
1243 force the channel key change anyway. The <hmac> argument is
1244 important since the client is responsible of setting the new
1245 HMAC and the hmac key into use.
1247 * Fixed the CMODE command in the client library as well.
1249 * Tested CMODE command in router environment successfully.
1251 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1253 * Show the version of the remote client (or server) when connecting
1254 to the server. It is logged to the log file. Affected file
1255 is silcd/protocol.c.
1257 * Fixed the KILLED notify handling in the client library. The
1258 client must be removed from all channels when receiving the
1261 Also, do not remove the client entry when giving the KILL
1262 command but when the KILLED notify is received.
1264 * Removed silc_idlist_find_client_by_nickname from the server.
1265 Not needed anymore. Affected files silcd/idlist.[ch].
1267 * Implemented the CHANNEL_CHANGE notify type handling to the
1268 server. Affected file silcd/server.c.
1272 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1274 * Added silc_server_send_notify_invite to send the INVITE
1275 notify between routers.
1277 * Implemented the INVITE command correctly to the server.
1279 * Implemented the INVITE notify type handling in the server.
1281 * Implemented the INVITE command to the client library and on the
1284 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1286 * Added function silc_server_get_client_resolve to find the
1287 client entry by ID from all ID lists and then resolve it
1288 (using WHOIS) if it cannot be found. Affected file is
1291 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1293 * Implemented the BAN command to the client library.
1295 * The JOIN command in the server now checks the invite list
1298 * Changed the silc_command_reply_payload_encode_va and the
1299 silc_command_payload_encode_va to support that if argument is
1300 NULL it ignores and checks the next argument. Affected file
1301 lib/silccore/silccommand.c.
1303 * Added silc_server_send_notify_ban to send the BAN notify
1304 type between routers.
1306 * Chaned the silc_notify_payload_encode to support that if
1307 argument is NULL it ignores and checks the next argument.
1308 Affected file lib/silccore/silcnotify.c.
1310 * Tested ban lists in router environment successfully.
1312 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1314 * Implemented BAN command to the server, in silcd/command.[ch].
1316 * Removed the BAN and INVITE_LIST modes from the CMODE command
1319 * Added function silc_string_match to regex match two strings.
1320 Affected files lib/silcutil/silcutil.[ch].
1322 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1324 * Redefined parts of the SilcChannelEntry in the server to support
1325 the new ban and invite lists.
1327 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1329 * Redefined the INVITE command. The same command can be used to
1330 invite individuals to the channel but also to manage the invite
1331 list of the channel (to add to and remove from the invite list).
1332 Updated the protocol specs.
1334 * Added new command SILC_COMMAND_BAN that can be used to manage
1335 the ban list of the channel. Updated the protocol specs.
1337 * Removed the channel modes: the SILC_CMODE_BAN and the
1338 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1339 in the CMODE command. The equivalent features are now available
1340 using INVITE and BAN commands. Updated the protocol specs.
1342 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1343 in the network about change in the current ban list. The notify
1344 type is not used by the client.
1346 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1347 support the invite lists.
1349 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1351 * Added new function silc_string_regexify that converts string
1352 including wildcard characters into regex string that can
1353 be used by the GNU regex library. Added into the file
1354 lib/silcutil/silcutil.[ch].
1356 Added silc_string_regex_combine to combine to regex strings
1357 into one so that they can be used as one regex string by
1358 the GNU regex library. Added into the file
1359 lib/silcutil/silcutil.[ch].
1361 Added silc_string_regex_match to match two strings. It returns
1362 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1364 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1366 * Imported GNU regex to the soruce tree into lib/contrib.
1367 Fixed some compiler warning from the regex.c.
1369 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1371 * Fixed MOTD command in the server to work in router environment.
1373 * Fixed the MOTD command in the client library to support
1374 the server argument in the command.
1376 * Added `nickname_len' argument to the silc_idlist_add_client
1377 in the server, as the `nickname' argument may be binary data
1380 * Added silc_idlist_get_channels to return all channels from
1383 * Implemented LIST command to the server. Affected file is
1386 * Implemented the LIST command to the client library and on the
1389 * Added [<user count>] argument to the LIST command reply.
1390 With private channels the user count is not shown.
1392 * Updated TODO and README.
1394 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1396 * The client entry's data.registered must be TRUE even with
1397 global client entry on global client list. The data.registered
1398 is used to check whether the client is anymore in the network,
1399 for example with WHOWAS command so it must be valid.
1401 * Fixed the WHOWAS command in the server. It now actually works
1402 in router environment. Added function into silcd/command_reply.c
1403 silc_server_command_reply_whowas_save.
1405 * Added silc_idlist_purge function to the silcd/idlist.c
1406 to periodically purge the ID Cache.
1408 * Fixed INFO command in the server. It works now in router
1409 environment. Added <server name> argument to the INFO command
1410 reply. Updated the protocol specs.
1412 * Fixed minor bug in silc_idcache_purge to not purge if the
1413 expire value is zero.
1415 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1416 they were buggy because of the WHOWAS information.
1418 * Fixed local command MSG to handle the async resolving of
1419 the remote client properly. It used to fail the first MSG.
1420 Affected file silc/local_command.c.
1422 * Added `data_len' field to SilcIDCache context.
1424 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1426 * Update TODO. Todo in commands in the server.
1428 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1430 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1431 used by routers as broadcast packet to inform other routers
1432 about the changed user mode.
1434 Implemented the notify handling in the server. Affected file is
1435 silcd/packet_receive.c. Added the function
1436 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1438 * Added new generic Channel Payload and deprecated the New Channel
1439 Payload. The New Channel Payload is now the generic Channel
1442 * Added new argument `mode' to the silc_server_send_new_channel
1443 as it is required in the Channel Payload now.
1445 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1446 and created a new and real SilChannelPayload to represent the
1447 new generic Channel Payload. Implemented the encode/decode
1448 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1450 * Added silc_server_get_client_channel_list to return the list
1451 of channels the client has joined for WHOIS command reply.
1452 Affected file silcd/server.[ch].
1454 * Implemented the channel list sending in the WHOIS command reply
1455 in server and in the client.
1457 Implemented the channel list displaying on the user interface
1458 as well. Affected file silc/client_ops.c.
1460 * Added silc_channel_payload_parse_list to parse list of Channel
1461 Payloads. It returns SilcDList list of SilcChannelPayloads.
1462 Client for example can use this function to parse the list of
1463 channels it receives in the WHOIS command reply. The caller
1464 must free the list by calling silc_channel_payload_list_free.
1465 Affected files lib/silccore/silcchannel.[ch].
1467 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1469 * Added one new argument <user mode> to the WHOIS command reply
1470 to return the mode of the user in SILC. Updated the protocol
1473 Implemented it to the server and client.
1475 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1477 * Fixed the mode printing on the user interface on joining.
1478 Affected file silc/client_ops.c.
1480 * Implemented the UMODE command and user modes in general to the
1481 client library and to the user interface.
1483 * Implemented the UMODE command to the server.
1485 * The server now sends UNKNOWN_COMMAND error status if client sends
1486 unknown command. Affected file silcd/command.c.
1488 * All server commands now handle the command identifier the right
1489 way when sending the command reply to the client. The client can
1490 use to identify the command replies with the identifier.
1492 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1494 * Added silc_server_get_client_route to resolve the route to
1495 the client indicated by the client ID. Affected file is
1498 * Added silc_server_relay_packet as general function to relay
1499 packet to arbitrary destination. This deprecates functions
1500 like _send_private_message_key, _relay_notify etc. Affected
1501 file is silcd/packet_send.[ch].
1503 Removed silc_server_send_key_agreement,
1504 silc_server_send_private_message_key and
1505 silc_server_packet_relay_notify functions from the file
1506 silcd/packet_send.[ch].
1510 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1511 server. Affected file silcd/packet_receive.[ch].
1513 * Implemented the KILL command to the client. Implemented the
1514 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1515 Affected files lib/silcclient/command[_reply].c and
1516 lib/silcclient/client_notify.c. Implemented the KILL notify
1517 printing in the user inteface.
1519 * Fixed a lot silc_parse_nick memory leaks from the client
1520 library in the file lib/silcclient/command.c.
1522 * Changed the silc_server_send_notify_on_channels's `sender'
1523 argument from SilcSocketConnection to SilcClientEntry to
1524 check the sender as entry and not as connection object and not
1525 to send to the client provided as argument. The affected file
1526 is silcd/packet_send.[ch].
1528 * The notify packets that are destined directly to the client used
1529 to not to be processed by the server. Now changed that and the
1530 server processes all notify packets. After relaying the packet
1531 to the client the notify packet is processed in the server.
1533 * The silc_server_free_client_data now checks whether there is
1534 pending outgoing traffic for the client and purges the data to
1535 the network before removing the client entry.
1537 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1539 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1540 an client is killed from the SILC Network. Updated the protocol
1543 Added new function silc_server_send_notify_killed to the
1544 silcd/packet_send.[ch].
1546 * Added function silc_server_packet_relay_notify to relay notify
1547 packets that are destined directly to a client. In this case
1548 the server does not process the notify packets but merely relays
1549 it to the client. Affected file silcd/packet_send.[ch].
1551 Added also silc_server_packet_process_relay_notify to check
1552 whereto relay the notify. Affected file is
1553 silcd/packet_receive.[ch].
1555 * Implemented the KILL command to the server.
1559 * Added the backup schema desgined last fall to the protocol
1560 specs for everyone to see. The specification is in the
1561 *-spec-xx.txt draft and the packet type definitions for the
1562 backup routers is in *-pp-xx.txt draft. Thusly, added also
1563 new packet type SILC_PACKET_CELL_ROUTERS.
1565 * A big security problem in the implementation discovered. The
1566 signoff of an client did not cause new channel key generation
1567 which it of course should've done. The channel keys must be
1568 always re-generated when client leaves (or signoffs) the channel.
1569 The silc_server_remove_from_channels funtion now handles
1570 the channel key re-generation.
1572 * Added `sender' argument to the silc_server_send_notify_on_channels
1573 to not to send the client provided as argument. Affected file
1574 silcd/packet_send.[ch].
1576 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Implemented OPER and SILCOPER commands into the server and
1581 * Added silc_auth_verify and silc_auth_verify_data to verify
1582 the authentication directly from the authentication payload.
1583 It supports verifying both passphrase and public key based
1584 authentication. Affected file lib/silccore/silcauth.[ch].
1586 * Added `hash' field to the SilcIDListData structure. It is the
1587 hash negotiated in the SKE protocol. Affected file is
1590 * Slight redesigning of the SilcAuthPayload handling routines.
1591 Do not send SilcPKCS but SilcPublicKey as argument.
1593 * Implemented the public key authentication support to the
1594 serverconfig. The public key is loaded from the provided path
1595 and saved as authentication data to void * pointer. Thus,
1596 changed the unsigned char *auth_data to void *auth_data;
1598 * Fixed SHUTDOWN command to send the reply before the server
1599 is shutdown. :) Affected file silcd/command.c.
1601 * Fixed fatal bug in CONNECT command. The hostname was invalid
1602 memory and server crashed. Affected file silcd/command.c.
1604 * Fixed fatal bug in CLOSE command. The server_entry became
1605 invalid but was referenced later in the command. Affected file
1608 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Fixed fatal bug in failure packet handling. Server ignored
1611 the failure and thus crashed when it came.
1615 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1617 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1618 that the command may be executed only once in (about) 2 seconds.
1619 The old SILC_CF_LAG flag is same but allows command bursts up
1620 to five before limiting.
1622 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1623 server code. Various commands now includes the CF_LAG_STRICT
1624 flag to disallow any kind of miss-use of the command.
1626 * Fixed the silc_buffer_unformat to not to allocate any data
1627 if the length of the data is zero. It used to allocate the
1628 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1630 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1632 * Changed the format of AdminConnection configuration section
1633 in the server. Added username of the admin to the format.
1634 Affected files silcd/serverconfig.[ch].
1636 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1637 to return admin configuration data by host, username and/or
1640 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1642 * Implemented WHOWAS command to the server. Added the functions:
1644 silc_server_command_whowas_parse,
1645 silc_server_command_whowas_send_reply,
1646 silc_server_command_whowas_from_client and
1647 silc_server_command_whowas_from_server
1649 * Added <Client ID> argument to the WHOWAS command reply. Updated
1650 the protocol specs accordingly.
1652 * Implemented WHOWAS command and command_reply to the client
1655 Implemented the WHOWAS printing on the user interface.
1657 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1659 * Added new argument to the WHOWAS command reply, the real name.
1660 It is an optional argument. Updated the protocol specs.
1662 * Added SilcIDCacheDestructor callback that is registered when
1663 the SilcIDCache is allocated. The callback is called when
1664 an cache entry in the ID Cache expires, or is purged from the
1665 cache. Added into lib/silccore/idcache.[ch].
1667 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1668 to destruct the client entries when the cache entry expires.
1669 Other ID Cache's in server and in the client library ignores
1672 * If the ID Cache entry's `expire' field is zero then the entry
1673 never expires. Added boolean `expire' argument to the
1674 silc_idcache_add function in the lib/silccore/idcache.[ch].
1675 If it is TRUE the default expiry value is used.
1677 * Added silc_server_free_client_data_timeout that is registered
1678 when client disconnects. By default for 5 minutes we preserve
1679 the client entry for history - for WHOWAS command.
1681 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1683 * Added support to the server to enforce that commands are not
1684 executed more than once in 2 seconds. If server receives
1685 commands from client more frequently, timeout is registered
1686 to process the commands. Affected file silcd/command.c.
1687 Added new function silc_server_command_process_timeout.
1689 * Changed NICK_NOTIFY handling in client library to check that
1690 if the client's nickname was changed, so there is no need to
1691 resolve anything from the server.
1693 * Removed error printing from the WHOIS and IDENTIFY commands.
1694 If error occurs then it is ignored silently in the client library.
1695 The application, however, may map the received error to
1696 human readable error string. The application currently maps
1697 the NO_SUCH_NICKNAME error to string.
1699 * Made the command status message public to the application. Moved
1700 them from lib/silcclient/command_reply.c to
1701 lib/silcclient/command_reply.h. The application can map the
1702 received command status to the string with the
1703 silc_client_command_status_message function.
1705 * Added check to the server to check that client's ID is same
1706 as the Source ID in the packet the client sent. They must
1709 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1711 * Added dist-bzip hook to the Makefile.am to make bzip2
1712 compressed distributions.
1714 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Server now enforces the maximum length for the nickname and
1717 the channel as protocol specification dictates. 128 bytes for
1718 nickname and 256 bytes for channel name.
1720 * Moved the WHOIS printing to the application. The client libary
1721 does not print out the WHOIS information anymore, the application
1722 must do it. Renamed silc_client_command_reply_whois_print to
1723 the silc_client_command_reply_whois_save.
1725 The client's idle time is also sent to the application now, and
1726 the idle is shown on screen.
1728 * Added silc_client_command_reply_identify_save to save the
1729 received IDENTIFY entries.
1731 * Do not check for channel private keys in message sending and
1732 reception if the channel does not have the PRIVKEY mode set.
1733 Affected file lib/silclient/client_channel.c.
1735 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1737 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1738 just surfaced after chaning the JOIN procedure.
1740 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1742 * Added silc_client_get_clients_by_list to get client entries
1743 from Client ID list, that is returned for example by JOIN
1744 and USERS command replies. The application should use this
1745 function for example when JOIN command reply is received to
1746 resolve the clients already on the channel (library does not
1747 do that anymore as USERS command reply is not used in the JOIN
1748 procedure anymore). Affected files lib/silcclient/silcapi.h and
1749 lib/silcclient/idlist.c.
1751 * JOIN command reply and USERS command reply returns now SilcBuffer
1752 pointers instead of unsigned char pointers when returning
1753 the client list and mode list.
1755 * Added <Client ID> argument to the JOIN command reply, mainly
1756 for the server to identify for which client the command was
1757 originally sent. Updated protocol specs accordingly.
1759 * Added SilcDlist private_key pointer to the SilcChannelEntry
1760 in the client to support the channel private keys. Affected
1761 file is lib/silcclient/idlist.h.
1763 * Added SilcChannelPrivateKey argument to the function
1764 silc_client_send_channel_message so that application can choose
1765 to use specific private ke if it wants to. If it is not provided,
1766 the normal channel key is used, unless private keys are set.
1767 In this case the first (key that was added first) is used
1768 as the encryption key.
1770 * Implemented the support for channel private key handling.
1771 Implemented the following functions:
1773 silc_client_add_channel_private_key,
1774 silc_client_del_channel_private_keys,
1775 silc_client_del_channel_private_key,
1776 silc_client_list_channel_private_keys and
1777 silc_client_free_channel_private_keys
1779 Affected file lib/silcclient/client_channel.c.
1781 * Added the support for the private keys in the channel message
1782 sending and encryption and in the message reception and
1783 decryption. Affected funtions are
1784 silc_client_send_channel_message and silc_client_channel_message.
1786 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Added SKE's key verify callback to the client library's
1789 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1791 * Removed the statement that server (or router) must send USERS
1792 command reply when joining to the channel so that the client
1793 knows who are on the channel. Instead, the client list and
1794 client's mode list is now sent in the JOIN command reply to the
1795 client who joined channel. This is better solution.
1797 * Added function silc_server_get_users_on_channel and function
1798 silc_server_save_users_on_channel to the silcd/server.[ch].
1800 * Removed function silc_server_command_send_users from the
1803 * Do not show topic on the client library anymore. The topic is
1804 sent in the command reply notify to the application and the
1805 application must show the topic now.
1807 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1809 * Added client searching by nickname hash into the IDENTIFY and
1810 WHOIS commands in the server as they were clearly missing from
1811 them. Affected file is silcd/command.c.
1813 * Fixed a bug in private message receiving in the client library.
1814 The remote ID was freed and it wasn't supposed, now it is
1817 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1819 * Minor fix to the channel payload; allocate the data area, as it
1820 needs to be of specific length.
1822 * If the key agreement port is zero then the operating
1823 system will define the bound port. Affected files are
1824 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1826 * Added new function silc_channel_payload_decrypt into the file
1827 lib/silccore/silcchannel.[ch].
1829 * Moved the channel message etc, check from silc_packet_decrypt
1830 to applications. The library calls now a generic
1831 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1832 when the packet is either normal or special. This was done to
1833 allow more wide range of checking that was not allowed when
1834 the code was in library. Now applications can do virtually any
1835 checks to the packet and return to the library the decision how
1836 the packet should be processed. Affected files are
1837 lib/silccore/silcpacket.[ch].
1839 Added silc_server_packet_decrypt_check to the server and
1840 silc_client_packet_decrypt_check to the client library.
1842 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1843 to send with specified source and destination information.
1845 * Channel message delivery between routers was broken after the
1846 channel key distribution was fixed earlier. The channel key
1847 was used be to distributed to other routers as well which is not
1848 allowed by the protocol. Now this is fixed and channel keys
1849 really are cell specific and the channel message delivery between
1850 routers comply with the protocol specification.
1852 * Fixed various commands in server to check also the global list
1853 for the channel entry and not just the local list. The affected
1854 file silcd/command.c.
1856 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1858 * Added assert()s to buffer formatting and unformatting routines
1859 to assert (if --enable-debug) when error occurs. Affected
1860 file: lib/silcutil/silcbuffmt.c.
1862 * Changed to auto-reconnect to check whether the remote host is
1863 router and register the re-connect timeout if it is. It used
1864 to check that whether we are normal server, but router must do
1865 auto-reconnect with another router as well. Affected file
1868 * Removed the [<key len>] option from CMODE command as the cipher
1869 name decides the key length, nowadays. See the defined ciphers
1870 from the protocol specification.
1872 * Added [<hmac>] option to the CMODE command to define the HMAC
1873 for the channel. Added SILC_CMODE_HMAC channel mode.
1875 * Added [<hmac>] option for the JOIN command so that user can
1876 select which HMAC is used to compute the MACs of the channel
1879 * Added Hmac field to the Channel Message Payload. The integrity
1880 of plaintext channel messages are now protected by computing
1881 MAC of the message and attaching the MAC to the payload. The
1882 MAC is encrypted. Now, it is clear that this causes some
1883 overhead to the size of the packet but rationale for this is that
1884 now the receiver can verify whether the channel message decrypted
1885 correctly and also when private keys are set for the channel the
1886 receiver can decrypt the packet with several keys and check from
1887 the MAC which key decrypted the message correctly.
1889 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1890 lib/silccrypt/silccipher.[ch].
1892 * Added silc_hash_len to return the digest length into the
1893 lib/silcrypt/silchash.[ch].
1895 * Rewrote parts of Silc Channel Payload interface in the
1896 lib/silccore/silcchannel.[ch]. The encode function now also
1897 encrypts the packet and parse function decrypts it.
1899 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1901 * Fixed a minor formatting bug in the SKE's key material processing.
1902 It actually might have processed the keys wrong way resulting
1905 * Redefined the mandatory HMAC algorithms and added new algorithms.
1906 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1907 and hmac-md5 truncated to 96 bits. The mandatory is now
1908 hmac-sha1-96. Rest are optional (including the one that used
1909 to be mandatory). Rationale for this is that the truncated HMAC
1910 length is sufficient from security point of view and can actually
1911 make the attack against the HMAC harder. Also, the truncated
1912 HMAC causes less overhead to the packets. See the RFC2104 for
1915 * Added new [hmac] configuration section. The SKE used to use
1916 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1917 is of course wrong. The official names that must be proposed in
1918 the SKE are the ones defined in the protocol specification
1919 (hmac-sha1-96 for example). The user can configure any hmac
1920 using any hash function configured in the [hash] section. At
1921 least, the mandatory must be configured.
1923 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1925 * Added HMAC list to the SKE proposal list. It has now both
1926 hash algorithm list and HMAC list. This makes the protocol
1927 incompatible with previous versions. The SKE now seems to work
1928 the way it is supposed to work, for the first time actually.
1930 * Defined plain Hash algorithms to the protocol specification.
1933 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1935 * Implemented support for key agreement packets into the server.
1936 Added functions silc_server_key_agreement and
1937 silc_server_send_key_agreement. Other than these functions,
1938 server has nothing to do with this packet.
1940 * Added support for private message key packets into the server.
1941 Added functions silc_server_private_message_key and
1942 silc_server_send_private_message_key.
1946 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1947 called in the protocol's final callback instead in the END
1948 protocol state. This makes a little more sense and in the same
1949 time in client we can use the same protocol routines for normal
1950 key exchange and to key agreement packet handling as well.
1952 * Added to both client's and server's KE protocol context the
1953 SilcSKEKeyMaterial pointer to save the key material. We will
1954 bring the key material to the protocol's final callback by doing
1955 this. The final callback must free the key material.
1957 * Added SKE's packet_send callback into client's KE protocol
1958 context so that the caller can choose what packet sending function
1959 is used. This way we can use different packet sending when
1960 doing normal SKE when doing key agreement packet handling (in
1961 the key agreement packet handling we do not want to encrypt
1964 * Implemented the responder side of the key agreement routines
1965 in the client. The client can now bind to specified port and
1966 accept incoming key negotiation. The key material is passed
1967 to the application after the protocol is over.
1969 * Implemented the processing of incoming Key Agreement packet
1970 in the client. Added function silc_client_key_agreement to
1973 * Implemented the intiator side of the key agreement routines
1974 in the client. The client can now initiate key agreement with
1975 another remote client. The key material is passed to the
1976 application after the protocol is over.
1978 * Created client_keyagr.c to include all the key agreement
1981 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1982 SILC_TASK_CALLBACK except that it is not static.
1984 * Created client_notify.c and moved the Notify packet handling
1985 from the client.[ch] into that file.
1987 * Created client_prvmsg.c and moved all private message and
1988 private message key routines from the client.[ch] into that file.
1990 * Create client_channel.c and moved all channel message and
1991 channel private key routines from the client.[ch] into that file.
1993 * Changed silc_client_get_client_by_id_resolve to resolve with
1994 WHOIS command instead of IDENTIFY command, in the file
1995 lib/silclient/idlist.c.
1997 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1999 * Implemented the SKE's responder side to the Client library.
2001 * When FAILURE is received to the protocol do not trust it
2002 blindly. Register a timeout to wait whether the remote closes
2003 the connection as it should do it, only after that process the
2004 actual failure. This was changed to both client and server.
2006 * Added client_internal.h to include some of the structures
2007 there instead of client.h in lib/silcclient/.
2009 * Added function silc_task_unregister_by_callback to unregister
2010 timeouts by the callback function.
2012 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2014 * Some "Incomplete WHOIS info" errors has been appearing on the
2015 log files. Took away the entry->userinfo check from WHOIS
2016 reply sending. The entry->userinfo is now " " if client did not
2017 provide one. I thought this was fixed earlier but something
2018 is wrong still. Let's see if the error still appears.
2020 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2022 * Fixed a minor bug in the login when the channel key is
2023 re-generated in the server. It used to generate the key in
2024 wrong order and thus caused problems in the channel traffic.
2026 * Fixed a minor bug in channel key distsribution after
2027 KICK command. The key was not sent to the router even though
2030 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2032 * Added silc_ske_process_key_material_data as generic routine
2033 to process any key material as the SILC protocol dictates. The
2034 function is used by the actual SKE library but can be used by
2035 applications as well. This relates to the private message keys
2036 and the channel private keys since they must be processed the
2037 same way the normal SILC session keys. The protocol dictates
2038 this. Affected files: lib/silcske/silcske.[ch].
2040 Added also silc_ske_free_key_material to free the
2041 SilcSKEKeyMaterial structure.
2043 * Defined silc_cipher_set_key function to set the key for
2044 cipher without using the object's method function. The affected
2045 files: lib/silccrypt/silccipher.[ch].
2047 * Implemented silc silc_client_add_private_message_key,
2048 silc_client_add_private_message_key_ske,
2049 silc_client_del_private_message_key,
2050 silc_client_list_private_message_keys and
2051 silc_client_free_private_message_keys functions in the
2054 Added functions silc_client_send_private_message_key to send
2055 the Private Message Key payload and silc_client_private_message_key
2056 to handle incoming Private Message Key payload.
2058 * Added Cipher field to the Private Message Key payload to set
2059 the cipher to be used. If ignored, the default cipher defined
2060 in the SILC protocol (aes-256-cbc) is used.
2062 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Removed lib/silcclient/ops.h file.
2066 Redefined parts of the SILC Client Library API. Created new
2067 file silcapi.h that deprecates the ops.h file and defines the
2068 published Client Library API. Defined also private message key
2069 API and channel private key API into the file.
2071 This is the file that the application must include from the
2072 SILC Client Library. Other files need not be included by
2073 the application anymore.
2075 * Added new key_agreement client operation callback and also
2076 defined the Key Agreement library API for the application.
2078 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2080 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2081 is used by clients to request key negotiation between another
2082 client in the SILC network. If the negotiation is started it
2083 is performed using the SKE protocol. The result of the
2084 negotiation, the secret key material, can be used for example
2085 as private message key.
2087 Implemented the Key Agreement payload into the files
2088 lib/silccore/silauth.[ch].
2090 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Redefined ciphers for the SILC protocol. Added some new ciphers
2093 and defined the key lengths for the algorithms. Changed the
2094 code accordingly. The default key length is now 256 bits.
2096 * Fixed SKE key distribution function silc_ske_process_key_material
2097 when the key length is more than 128 bits. The default key
2098 length in SILC is now 256 bits.
2100 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2101 to indicate unsupported algorithm.
2103 * Renamed rijndael.c to aes.c and all functions as well.
2105 * Fixed a long standing channel key setting bug in client library.
2106 Weird that it has never surfaced before.
2108 * Fixed bug in channel deletion. If the entire channel is removed
2109 then it must also delete the references of the channel entry
2110 from the client's channel list as the client's channel entry and
2111 the channel's client entry share same memory.
2113 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2115 * Implemented CONNECT and SHUTDOWN commands in the client.
2117 * Implemented CLOSE command to the client.
2119 * Added the function silc_idlist_find_server_by_name into the
2120 files silcd/idlist.[ch].
2122 Added the function silc_idlist_find_server_by_conn into the
2123 files silcd/idlist.[ch].
2125 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * DIE command was renamed to SHUTDOWN. Updated the both code
2130 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2131 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2133 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2136 * Added function silc_server_create_connection function to create
2137 connection to remote router. My server implementation actually
2138 does not allow router to connect to normal server (it expects
2139 that normal server always initiates the connection to the router)
2140 so the CONNECT command is only good for connecting to another
2143 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2145 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2146 or some other client was kicked from the channel.
2148 Implemented the handling of the notify type to both client
2151 Implemented silc_server_send_notify_kicked to send the KICKED
2152 notify. It is used to send it to the server's primary router.
2154 * Implemented the KICK command into server and client.
2156 * Added `query' argument to the silc_idlist_get_client function
2157 to indicate whether to query the client from server or not if
2160 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2161 to indicate that the client is not channel founder.
2165 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2167 * Removed the rng context from SilcPacketContext structure and
2168 changed that the packet routine uses the Global RNG API.
2170 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Added support for quit message that client can "leave" on the
2173 channel when it quits the SILC. It is ditributed inside the
2174 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2176 Added silc_server_free_client_data that will take the
2177 signoff message as argument.
2179 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2181 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * Updated parts of the protocol specification to keep it up
2186 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2188 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2189 payloads in one packet.
2191 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2192 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2193 use now the new List flag.
2195 * Also deprecated the following packet types: REPLACE_ID,
2196 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2198 * Added list support for Notify packet in server.
2200 * Added silc_server_send_notify_channel_change to send the
2201 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2202 the silc_server_send_replace_id.
2204 * Added silc_server_send_notify_nick_change to send the
2205 NICK_CHANGE notify type. Deprecates the function
2206 silc_server_send_replace_id.
2208 * Added silc_server_send_notify_join to send the JOIN notify type.
2209 Deprecates the function silc_server_send_new_channel_user.
2211 * Added silc_server_send_notify_leave to send LEAVE notify type.
2212 Deprecates the function silc_server_send_remove_channel_user.
2214 * Added silc_server_send_notify_cmode and
2215 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2216 types. Deprecates the silc_server_send_set_mode function.
2218 * Added SERVER_SIGNOFF notify type to indicate that server has
2219 quit. This means that all clients on the channel from that
2220 server will drop. This can be also used when netsplit happens.
2222 Deprecated REMOVE_ID packet type since it is not needed anymore
2225 Added silc_server_send_notify_server_signoff to send the
2226 SERVER_SIGNOFF notify type. Deprecates the function
2227 silc_server_send_remove_id.
2229 Added also silc_server_send_notify_signoff to send the
2230 SIGNOFF notify type.
2232 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2233 SILC protocol from this day on. Changed the protocol
2234 specification as well.
2236 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2237 notify type. It is used between routers to notify about
2238 topic changes on a channel.
2240 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2243 * Partly updated the protocol specification to comply with the
2244 changes now made. It is still though a bit outdated.
2246 * The JOIN notify type now takes one extra argument <Channel ID>.
2247 The packet used to be destined to the channel but now the
2248 JOIN type may be sent as list thus it is impossible to
2249 destine it to any specific channel. By adding this argument
2250 it is again possible.
2252 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2254 * Added CREDITS file. The CHANGES and CREDITS file will appear
2255 in the distribution as well.
2257 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2259 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2260 types in the server's silcd/packet_receive.c.
2262 * Implemented CMODE and CUMODE to work in router environment.
2264 * Fixed minor encoding and decoding buglet from the
2265 lib/silccore/silcmode.c.
2267 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2270 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2272 * Changed all SilcConfigServer* and silc_config_server* to
2273 SilcServerConfig* and silc_server_config*, respectively.
2276 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Associated the ID (client or server ID) to the Authentication
2279 Payload to avoid any possibility of forging. Updated the
2280 protocol specification and the code accordingly.
2282 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2284 * The RSA key length is now save to the RsaKey context in the
2285 key generation process in lib/silccrypt/rsa.c. The key length
2286 is now used to figure out the maximum size of the block allowed
2287 to be encrypted/signed.
2289 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2290 is equivalent to the silc_mp_mp2bin but does not allocate any
2293 * Changed silc_mp_mp2bin API to take length argument. If it is
2294 non-zero then the buffer is allocated that large. If zero, then
2295 the size is approximated using silc_mp_sizeinbase, which however
2298 * Created Global RNG API which is global RNG that application can
2299 initialize. After initializing, any routine anywhere in the
2300 code (including library) can use RNG without allocating a new
2301 RNG object. This was done to allow this sort of use of the
2302 RNG in code that has no chance to allocate RNG object. All
2303 applications currently allocate this and many routines in the
2304 library use this. Affected file lib/silccrypt/silcrng.[ch].
2306 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2307 it to use the Global RNG API.
2309 * Defined Authentication Payload into protocol specification that
2310 is used during SILC session to authenticate entities. It is
2311 used for example by client to authenticate itself to the server
2312 to obtain server operator privileges.
2314 Implemented this payload into the lib/silccore/silcauth.[ch].
2315 Implemented also routines for public key based authentication
2316 as the new protocol specification dictates.
2318 Moved definitions of different authentication methods from
2319 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2321 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2322 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2323 silc_pkcs_verify_with_hash functions into the file
2324 lib/silccrypt/silcpkcs.[ch].
2326 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2328 * The client entry's userinfo pointer must be always valid.
2329 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2330 will fail since it requires the userinfo. Now, the userinfo
2331 is allocated as "" if actual userinfo does not exist. Actually,
2332 it must exist and it is totally Ok to drop client connections
2333 that does not announce the userinfo. However, we will make
2334 this workaround for now.
2336 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2337 to return the remote port by socket.
2339 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2342 SILC_SERVER_PENDING_EXEC and added an new macro
2343 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2344 data or when error occurs while processing the pending command.
2346 Added new argument `destructor' into silc_server_command_pending
2347 and to the SilcServerCommandPending object. This destructor is
2348 now called after calling the pending callback or if error occurs
2349 immediately. If error occurs the actual pending callback won't
2350 be called at all - only the destructor. The destructor may be
2351 NULL if destructor is not needed.
2353 All this applies for client library code as well. Similar
2354 changes were made there as well for the pending commands.
2356 In the client, the application must now allocate the
2357 SilcClientCommandContext with the silc_client_command_alloc
2360 * Added reference counter to the SilcServerCommandContext. Added
2361 function silc_server_command_alloc and silc_server_command_dup
2364 Same type of functions added to the client library for the same
2367 * Removed the cmd_ident from IDListData away since it is now
2368 global for all connections. It is the command identifier used
2369 in command sending and with pending commands. The affected file
2372 * Added reference counter to the SilcSocketConnection objecet to
2373 indicate the usage count of the object. The object won't be
2374 freed untill the reference counter hits zero. Currently only
2375 server uses this, and client ignores it. The client must be
2376 set to use this too later. The affected files are
2377 lib/silccore/silcsockconn.[ch]. Added also the function
2378 silc_socket_dup to increase the reference counter.
2380 This was mainly added because it is possible that the socket
2381 is removed underneath of pending command or other async
2382 operation. Now it won't be free'd and proper DISCONNECTING
2383 flags, etc. can be set to avoid sending data to connection that
2384 is not valid anymore.
2386 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2387 the connection. After that it sets SILC_SET_DISCONNECTED.
2388 It is, however, possible that the socket data is not still freed.
2389 The silc_server_packet_process now checks that data is not
2390 read or written to connection that is DISCONNECTED. The socket
2391 get's freed when the reference counter hits zero.
2393 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Changed the client operation API: channel_message operation's
2396 `sender' is now the client entry of the sender, not the nickname
2397 and the `channel' is the channel entry, not the channel name.
2399 In the private_message operation the `sender' is now also the
2400 client entry of the sender not the nickname.
2402 Affected file is lib/silcclient/ops.h and all applications
2403 using the client operations.
2405 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2407 * Moved the calling of ops->connect() from connect_to_server_final
2408 into receive_new_id functin since that is the point when the
2409 client is actually allowed to send traffic to network. The
2410 affected file is lib/silcclient/client.c.
2412 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2414 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2415 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2416 (if needs broadcasting) instead of broadcasting the packets one
2417 by one which would make a burst in the network traffic.
2419 * Added `broadcast' argument to the functions in silcd/server.[ch]
2420 silc_server_create_new_channel[_with_id] to indicate whether
2421 to send New Channel packet to primary router.
2423 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2425 * Added new function into the silcd/server.[ch] files:
2426 silc_server_create_new_channel_with_id to create new channel with
2427 already existing Channel ID.
2429 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2430 lib/silccore/silcpacket.h. This packet is used t send list of
2431 Set Mode payloads inside one packet. Server uses this to set
2432 the modes for the channels and clients on those channels, that it
2433 announced to the router when it connected to it. The protocol
2434 specification has been updated accordingly.
2436 * The silc_server_new_channel did not handle the packet coming
2437 from normal server as it normally does not send that. However,
2438 when it announces its channels it does send it. Implemented
2439 the support for that.
2441 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2442 into the file lib/silccore/id.h.
2444 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Fixed memory leaks in the functions silc_idlist_del_client,
2447 silc_idlist_del_channel and silc_idlist_del_server in the file
2448 silcd/idlist.c. All of those leaked like a sieve.
2450 * Fixed some small memory leaks in the client's function
2451 silc_client_notify_by_server.
2453 * Added functions into silcd/server.c: silc_server_announce_clients,
2454 silc_server_announce_channels and silc_server_announce_server.
2455 These functions are used by normal and router server to announce
2456 to its primary router about clients, channels and servers (when
2457 router) that we own. This is done after we've connected to the
2460 These functions effectively implements the following packet types:
2461 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2462 and SILC_PACKET_NEW_ID_LIST.
2464 * Added new functions into the silcd/packet_receive.[ch]:
2465 silc_server_new_id_list, silc_server_new_channel_list and
2466 silc_server_new_channel_user_list to handle the incoming
2467 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2469 * Added support of changing Channel ID in the function
2470 silc_server_replace_id. If the server that announces a channel
2471 to the router already exists in the router (with same name but
2472 with different Channel ID), router is responsible to send
2473 Replace ID packet to the server and force the server to change
2474 the Channel ID to the one router has.
2476 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2477 client that the Channel ID has been changed by the router. The
2478 normal server sends this to the client. Client must start using
2479 the new Channel ID as the channel's ID.
2481 Implemented handling of this new type into lib/silcclient/client.c
2482 into the function silc_client_notify_by_server.
2484 * Added new function silc_idlist_replace_channel_id into the files
2485 silcd/idlist.[ch] to replace the Channel ID.
2487 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2489 * Call silc_server_command_identify_check always when processing
2490 the IDENTIFY command in silcd/command.c
2492 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2495 send keepalive packets. The packet can be sent by clients,
2496 servers and routers.
2498 Added function silc_socket_set_heartbeat into the file
2499 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2500 If not set, the heartbeat is not performed. The actual
2501 heartbeat is implemented in the low level socket connection
2502 library. However, application is responsible of actually
2505 Added silc_server_send_heartbeat to send the actual heartbeat
2506 packet into silcd/packet_send.[ch]. Server now performs
2507 keepalive with all connections.
2509 * Added silc_task_get_first function into lib/silcutil/silctask.c
2510 to return the timeout task with shortest timeout. There was a bug
2511 in task unregistration that caused problems. TODO has been
2512 updated to include that task system must be rewritten.
2514 * The client library will now resolve the client information when
2515 receiving JOIN notify from server for client that we know but
2516 have incomplete information.
2518 * Rewrote parts of silc_server_remove_from_channels and
2519 silc_server_remove_from_one_channel as they did not remove the
2520 channel in some circumstances even though they should've.
2522 * Encryption problem encountered in server:
2524 The LEAVE command used to send the Channel Key packet to the
2525 router immediately after generating it. However, the code
2526 had earlier sent Remove Channel user packet but not immediately,
2527 ie. it was put to queue. The order of packets in the router
2528 was that Channel Key packet was first and Remove Channel User
2529 packet was second, even though they were encrypted in the
2530 reverse order. For this reason, MAC check failed. Now, this
2531 is fixed by not sending the Channel Key packet immediately but
2532 putting it to queue. However, this is more fundamental problem:
2533 packets that are in queue should actually not be encrypted
2534 because packets that are sent immediately gets encrypted
2535 actually with wrong IV (and thus MAC check fails). So, packets
2536 that are in queue should be encrypted when they are sent to
2537 the wire and not when they put to the queue.
2539 However, the problem is that the current system has not been
2540 designed to work that way. Instead, the packet is encrypted
2541 as soon as possible and left to the queue. The queue is then
2542 just purged into wire. There won't be any fixes for this
2543 any time soon. So, the current semantic for packet sending
2546 o If you send packet to remote host and do not force the send
2547 (the packet will be in queue) then all subsequent packets to the
2548 same remote host must also be put to the queue. Only after the
2549 queue has been purged is it safe again to force the packet
2552 o If you send all packets immediately then it safe to send
2553 any of subsequent packets through the queue, however, after
2554 the first packet is put to queue then any subsequent packets
2555 must also be put to the queue.
2557 Follow these rules and everything works fine.
2559 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2561 * Added new function silc_server_remove_clients_by_server to
2562 remove all client entries from ID list when the server connection
2563 is lost. In this case it is also important to invalidate all
2564 client entires as they hold the invalid server entry. This
2565 fixes fatal bug when server has lost connection and will reconnect
2568 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Made some sanity checks to silc_server_daemonise like to check
2571 whether the requested user and group actually exists.
2573 * Added sanity check to SKE's silc_ske_responder_finish to check
2574 that the public and private key actually is valid.
2576 * Invalidate the client's nickname when receiving Replace ID
2577 packet and the Client ID is being replaced. This means that the
2578 server will query the nickname if someone needs it (client)
2581 * Sort the ID Cache in client library when the ID Cache data
2582 has changed (needs sorting).
2584 * Do not allow for SILC client to create several connections to
2585 several servers. The client does not support windows right now
2586 and generating multiple connections causes weird behaviour.
2588 Irssi-silc client does support windows and can handle several
2589 connections without problems, see: www.irssi.org and SILC plugin.
2591 * Fixed some places where client was added to the IDList. The
2592 rule of thumb is following (in order to get everything right):
2593 If the client is directly connected local client then the
2594 `connection' argument must be set and `router' argument must be
2595 NULL to silc_idlist_add_client function. If the client is not
2596 directly connected client then the `router' argument must
2597 bet set and the `connection' argument must be NULL to the
2598 silc_idlist_add_client function.
2600 * The funtion silc_server_packet_send_local_channel actually did
2601 not check whether the client was locally connected or not. It
2602 does that now. Fixed a bug related to LEAVE command.
2604 * Fixed Remove Channel User payload parsing bug in server's
2605 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2607 * The server's silc_server_save_channel_key now checks also the
2608 global ID list for the channel as it might not be in the local
2609 list. Fixed a bug related to LEAVE command.
2611 * Is this the end of the [<unknown>] buglet that has been lurking
2612 around for a long time? A little for loop fix in server's
2613 silc_server_command_whois_parse that is used by both IDENTIFY
2614 and WHOIS command. At least, this was a clear bug and a cause
2615 of one type of [<unknown>] buglet.
2617 * WHOIS and IDENTIFY commands call the function
2618 silc_server_command_[whois/identify]_check function even if
2619 we are not router server.
2621 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Added --with-gmp configuration option. If set the GMP
2624 is always compiled in the SILC source tree. If not set then
2625 it is checked whether the system has the GMP3 installed. If
2626 it has then the GMP won't be compiled (the system's headers
2627 and library is used), if it doesn't have it then the GMP is
2628 compiled in the SILC source tree.
2630 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2632 * Changed RSA private exponent generation to what PKCS #1
2633 suggests. We try to find the smallest possible d by doing
2634 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2635 not security fix but optimization.
2637 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Added new config entry [Identity] to fork the server and run
2640 it as specific user and group. A patch from Bostik.
2642 * Imported Dotconf configuration library into lib/dotconf.
2643 This will be used to create the SILC configuration files later.
2644 It will appear in the distsribution after this commit.
2646 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * A big code auditing weekend happening. Auditing code for
2649 obvious mistakes, bugs and errors. Also, removing any code
2652 Removed files for being obsolete:
2654 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2655 inline in the file lib/silcutil/silcbuffer.h)
2657 o lib/silcutil/silcbufutil.c (the header has inline versions)
2659 Changed code to fix possible error conditions:
2661 o The buffer formatting routines now check that the destination
2662 buffer really has enough space to add the data. This applies for
2663 both buffer formatting and unformatting
2664 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2665 unformatting was changed to accomodate following rules:
2666 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2667 sent to the function while XXX_*STRING will not allocate or copy
2668 the data into the buffer. Instead it sets the pointer from the
2669 buffer into the pointer sent as argument (XXX_*STRING used to
2670 require that the pointer must be allocated already). This change
2671 makes this whole thing a bit more consistent and more optimized
2672 (note that the data returned in the unformatting with XXX_*STRING
2673 must not be freed now). The routines return now -1 on error.
2675 o Tried to find all code that use buffer_format and buffer_unformat
2676 and added return value checking to prevent formatting and
2677 especially unformatting errors and possible subsequent fatal
2680 o Changed ske->x and ske->KEY to mallocated pointers in
2681 lib/silcske/silcske.h. Fixed possible data and memory leak.
2683 o Added return value checking to all *_parse* functions. Fixed
2684 many memory leaks as well.
2686 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2687 so that buffer overflows would not happen. All code now also
2688 checks the return value as it can fail.
2690 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2692 * Added reconnection support to server if the normal server looses
2693 its connection to the router (for example if router is rebooted).
2694 The server performs normal reconnection strategy implemented
2695 to the server. Affected file silcd/server.c.
2697 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * Added new packet type SILC_PACKET_SET_MODE that is used to
2700 distribute the information about changed modes (for clients,
2701 channels and clients channel modes) to all routers in the
2702 network. Updated the protocol specification accordingly.
2704 Added functions into silcd/packet_send.c and
2705 silcd/packet_receive.c: silc_server_send_set_mode,
2706 silc_server_set_mode.
2708 Added new files silcmode.[ch] into lib/silccore that implements
2709 the encoding and decoding of Set Mode Payload. Added new type
2710 SilcSetModePayload. Moved the definitions of different modes
2711 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2713 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2715 * Oops, a little mistake in server's connection authentication
2716 protocol. The protocol is not ended with FAILURE but with
2717 SUCCESS if the authentication is Ok. :) Affected file is
2720 * Implemented NICK_CHANGE notify handling in server in the file
2721 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2722 the local clients on the channel. After the changing nickname
2723 in router environment snhould work and the [<unknown>] nickname
2724 should appear no more.
2726 The silc_server_replace_id function that receives the Replace ID
2727 payload now sends the NICK_CHANGE notify type also in the file
2728 silcd/packet_receive.c
2730 * Changed WHOIS and IDENTIFY command to support the maximum amount
2731 of arguments defined in protocol specs (3328 arguments). This
2732 fixed a bug that caused problems when there were more than three
2735 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Added extra parameter, command identifier, to the
2738 silc_client_send_command so that explicit command identifier
2741 Changed that ID list routines uses specific command identifier
2742 when sending WHOIS/IDENTIFY requests to the server so that they
2743 can be identified when the reply comes back.
2745 Affected files lib/silcclient/command.[ch],
2746 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2748 * Added `sender' argument to silc_server_packet_send_to_channel
2749 to indicaet the sender who originally sent the packet to us
2750 that we are now re-sending. Ignored if NULL. Affected file
2751 silcd/packet_send.[ch].
2753 * Added some server statistics support in silcd/server_internal.h
2754 SilcServerStatistics structure and around the server code. Also
2755 send some nice statistics information when client is connecting
2758 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2760 * Fixed channel ID decoding in server's JOIN command reply in
2761 silcd/command_reply.c
2763 * Fixed braodcasting of replace ID payload to not to send it if
2764 we are standalone server in silcd/packet_receive.c.
2766 * Fixed all channel message sending routines to not to send
2767 packets to clients that has router set, since they are routed
2768 separately in the same function earlier. Affects file
2769 silcd/packet_send.c and all channel packet sending functions.
2771 * In USERS reply, res_argv[i] are not allocated, the table
2772 is allocated. Thus changed that free the table, not its
2775 * In server's whois_check and identify_check if the client is
2776 locally connected do not send any WHOIS commands - they are not
2779 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2781 * Fixed some minor bugs in client when sending WHOIS command. The
2782 arguments was in wrong order.
2784 * Removed statis function add_to_channel from server in
2785 silcd/command.c that was previously used with the joining but
2788 * Tested USERS command in router environment successfully with two
2789 routers, two servers and two clients.
2791 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Reorganized the USERS command and command reply in client library
2794 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2795 When the command is given by user we register a pending command
2796 callback that will reprocess the command after the reply has been
2797 received from the server. When reprocessing the packet we then
2798 display the information. Thus, the USERS information is displayed
2799 now in the command callback instead of in the command reply
2800 callback. The processing of the command is same as previously
2801 when server has sent the command reply in the JOINing process.
2803 * Added to USERS command in silcd/command_reply.c to join the client,
2804 we didn't use to know about, to the channel after we've created
2805 a client entry for it. Also, for clienet we did know already still
2806 check whether it is on the channel or not and add it if not.
2808 * Removed silc_server_command_join_notify as the function and its
2811 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2813 * Changed the client's pending command handling to the same as the
2814 server's pending command handling. It is also now possible to
2815 execute command reply functions from other command reply
2816 function as the function callbacks for commands and command
2817 replies are one and same. The pending commands are not static
2818 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2819 in client connection context. Thus, pending commands are server
2820 connection specific as it is convenient.
2822 Changed the function silc_client_command_pending and
2823 silc_client_command_pending_del and added new function
2824 silc_client_command_pending_check. Removed the
2825 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2828 * Added cmd_ident, current command identifier, to the client
2829 connection context in lib/silcclient/client.h to keep track on
2830 command identifiers used in command sending. Client's command reply
2831 function handling now supports the mandatory command identifiers.
2833 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2834 funtions in client to fully support pending command callbacks.
2836 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2837 as one of the arguments to the application in the command reply
2840 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2841 before first releasing SILC but came back. Now it is removed again
2842 and should come back nomore. The FORWARDED flag was used only
2843 by the JOINing procedure by forwarding the command packet to router.
2844 Now, the JOINing procedure has been changed to more generic (due
2845 to various router environment issues) and FORWARDED is not needed
2846 anymore for anything. The protocol specification is yet to be
2849 Now, removed silc_server_packet_forward from server and the flag
2850 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2852 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Renamed NAMES command to USERS command. The NAMES was named that
2855 due to historical reasons. Now it is renamed. Also, rewrote
2856 parts of the USERS command. The nickname list is not sent anymore
2857 by the server. Only Client ID and mode lists are sent in the USERS
2858 command. Changed this also to the protocol specification.
2860 The client now resolves the names and stuff after it receives
2861 the USERS list from the server when joining to the channel.
2863 * WHOIS and IDENTIFY commands has been changed to support multiple
2864 Client ID's per command. One can now search for multiple users
2865 in the network by sending only one WHOIS or IDENTIFY command.
2866 Changed the code and the protocol specifications.
2868 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2869 uses silc_server_command_whois_parse to parse the request. */
2871 * If normal server, do not parse the WHOIS and IDENTIFY requests
2872 before sending it to the router. Saves some time.
2874 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Fixed JOIN command on client library. Wrong number of arguments
2877 used to crash the client.
2879 * Added silc_server_channel_has_global function to check whether
2880 channel has global users or not.
2882 * Added silc_server_channel_has_local function to check whether channel
2883 has locally connected clients on the channel.
2885 * The silc_server_remove_from_one_channel now checks whether the
2886 channel has global users or not after given client was removed from
2887 the channel. It also checks whether the channel has local clients
2888 on the channel anymore. If it does not have then the channel entry
2889 is removed as it is not needed anymore.
2891 * The silc_server_notify now checks on JOIN notify whether the joining
2892 client is one of locally connected or global. If it is global then
2893 the channel has now global users on the channel and that is marked
2894 to the channel entry. Also, it now saves the global client to
2895 global list who is joining and JOINs it to the channel. This is
2896 for normal server, that is.
2898 Changed silc_server_send_notify_on_channel,
2899 silc_server_packet_relay_to_channel and
2900 silc_server_packet_send_to_channel check if we are normal server
2901 and client has router set (ie. global client) do not send the
2902 message to that client, as it is already routed to our router.
2904 * Implemented LEAVE notify type handling in silc_server_notify
2907 * Tested LEAVE command in router environment successfully. Tested
2908 with two routers, two servers and two clients.
2912 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2914 * Implemented SIGNOFF notify type handling in silc_server_notify
2917 * silc_server_remove_id now removes the client entry from all channels
2918 it has joined and thusly sends SIGNOFF notify type.
2920 * Rewrote the NAMES list generation in server by removing two excess
2921 loops. The lists are created now inside one loop.
2923 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * silc_server_remove_channel_user checks now also global list
2926 for channel and client.
2928 * silc_server_new_channel_user checks now both local and global
2929 list for channel and client. Fixed a bug in client id decoding.
2930 Used to decode wrong buffer.
2932 * silc_server_channel_message checks now both local and global
2933 list for channel entry.
2935 * Tested channel joining (hence JOIN) in router environment
2936 successfully. Tested with two routers, two servers and two
2939 * Tested channel message sending in router environment successfully.
2941 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2943 * Added silc_server_save_channel_key into server.[ch] to save the
2944 received channel key in Channel Key payload processing. It is
2945 also used in JOIN command reply handling.
2947 Equivalent function silc_client_save_channel_key added into
2948 client.[ch] into client library.
2950 * Changed JOIN command reply to send information whether the channel
2951 was created or not (is existing already) and the channel key
2952 payload. Changed protocol specs accordingly.
2954 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2955 the request was sent by ID and not by nickname. Crashed on
2958 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2960 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2961 now correctly save the received data.
2963 * silc_server_free_sock_user_data now notifies routers in the
2964 network about entities leaving the network.
2966 At the same time implemented functions silc_server_remove_id
2967 and silc_server_send_remove_id to receive and send REMOVE_ID
2968 packets. The packet is used to notify routers in the network
2969 about leaving entities. The ID removed will become invalid in
2972 * Added function silc_idlist_del_server into server. Removes and
2973 free's server entry from ID list.
2975 * silc_server_private_message function now checks, if we are router,
2976 that the destination ID really is valid ID, naturally.
2978 * In router when NEW_ID packet is received (for new client) the
2979 hash of the Client ID is saved in the ID Cache but the
2980 client->nickname is set to NULL, instead of putting the hash
2983 IDENTIFY command now also checks that client->nickname must be
2984 valid. If it is not if will request the data from the server who
2985 owns the client. Added new function
2986 silc_server_command_identify_check.
2988 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2989 to set the command to already allocated Command Payload.
2991 * Tested private message sending in router environment with two
2992 routers, two servers and two clients. Fixed minor bugs and now
2995 * Fixed segfault from client's NAMES command. Used to crash if
2998 * Forwarded packets must not be routed even if it is not destined
2999 to the receiver. Changed server code comply with this.
3001 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3003 * Added `require_reverse_mapping' boolean value to ServerParams
3004 structure. If TRUE (not default) the server will require that
3005 the connecting host has fully qualified domain name.
3007 If the reverse mapping is not required and hostname could not be
3008 found the IP address is used as hostname.
3010 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Implemented version string checking to both client and server.
3013 The check is incomplete currently due to the abnormal version
3014 strings used in development version of SILC.
3016 * Changed all command functions in server to use the new
3019 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Changed char *data to unsigned char *data in ID Cache system to
3022 support binary data as ID Cache data. Changed code to support
3023 binary data in lib/silccore/idcache.c.
3025 * Renamed silc_server_packet_relay_command_reply to
3026 silc_server_command_reply as it is normal packet receiving
3027 function. Rewrote the function to accept command replys for
3028 servers and not only for clients.
3030 * Mark remote router always as registered server if we are connecting
3031 to it. Otherwise, commands sent by the router to us are ignored.
3033 * All ID List find routines now returns the ID Cache Entry pointer
3034 as well if requested.
3036 * WHOIS command works now in router environment, tested with two
3037 routers, two servers and two clients.
3039 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3040 in router environment (as it is almost equivalent to WHOIS) but
3041 hasn't been tested thoroughly. Added new functions:
3043 silc_server_command_identify_parse
3044 silc_server_command_identify_send_reply
3045 silc_server_command_identify_from_client
3046 silc_server_command_identify_from_server
3048 * Disabled route cache adding because adding two different ID's with
3049 same IP replaces the old cache entry thus giving wrong route.
3050 The entry->router->connection is always the fastest route anyway
3051 so route cache may not be needed. Of course, new routes maybe
3052 established after receiving the ID when the entry->router->connection
3053 might not be anymore the most optimal.
3055 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Add route cache for received ID for fast routing.
3059 * Added silc_server_packet_route to route received packet on router
3060 that is not destined to us.
3062 * Renamed silc_server_get_route to silc_server_route_get.
3064 * Added id_string and id_string_len fields into SilcServer to
3065 include encoded ServerID for fast comparing without excess
3066 encoding of the ID's.
3068 * Cleaned up WHOIS command on server side. Added following static
3071 silc_server_command_whois_parse
3072 silc_server_command_whois_check
3073 silc_server_command_whois_send_reply
3074 silc_server_command_whois_from_client
3075 silc_server_command_whois_from_server
3077 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3078 arguments in command replies. All command functions should be
3079 updated to use this macro.
3081 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Minor typo fixes on command reply handling on server.
3085 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * Added silc_server_command_add_to_channel internal routine to add
3088 the client to the channel after router has created the channel and
3089 sent command reply to the server.
3091 * Added generic silc_server_send_command to send any command from
3094 * Use static buffer with ID rendering instead of duplicating data.
3096 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Fixed a channel user mode bug when joining to a channel server gave
3099 everybody channel founder rights, oops.
3101 * We mark ourselves as the router of the incoming server connection
3102 if we are router ourselves. This way we can check in some packet
3103 sending functions whether it is locally connected server. For
3104 incoming router connections we put NULL.
3106 * For router sending packets locally means now always sending the
3107 packet cell wide; to local clients and local servers. For normal
3108 server sending packet locally means sending it to only local
3111 * Fixed the JOIN command to really work in router environment. If the
3112 channel is created it is always created by the router. Router is
3113 also responsible of making the initial joining to the channel,
3114 sending JOIN notify to the sending server and distributing
3115 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3116 does not exist server doesn't do anything else but forward the
3117 command to the router which performs everything.
3119 * Added silc_server_send_channel_key function to send the Channel Key
3122 * Added silc_server_create_channel_key to create new channel key. The
3123 channel key is now re-generated everytime someone joins or leaves
3124 a channel, as protocol dictates. Note: channel->key_len is the
3127 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3130 packet_receive.[ch] to separate packet sending and receiving
3131 routines. The server.[ch] now includes everything else including
3132 actual packet processing (writing and reading data) and other
3135 Renamed silc_server_private_message_send_internal to
3136 silc_server_send_private_message. The routine is still though
3137 used only to relay private messages as server does not send
3138 private messages itself.
3140 Renamed silc_server_new_channel to silc_server_create_new_channel
3141 and added new function sicl_server_new_channel that handles the
3142 incoming New Channel packet. Added also new sending function
3143 silc_server_send_new_channel to send New Channel Payload.
3145 * Added new function silc_server_notify to process incoming notify
3146 packet to the server/router. Server may then relay the notify
3147 to clients if needed.
3149 * Added new function silc_server_new_channel_user to process incoming
3150 New Channel User packet. Router will redistribute the packet and
3151 send JOIN notify to its local clients and locally connected servers
3152 if needed. Normal server will send JOIN notify to its local client
3153 on same channel when received this packet. Added also corresponding
3154 sending function silc_server_send_new_channel_user to sent the
3157 * Added boolean route argument to send_notif_to_channel and
3158 packet_send_to_channel functions to attempt to route the packet
3159 if it is TRUE and send only locally if it is FALSE.
3161 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * silc_server_replace_id now broadcasts the received replace ID
3164 packet if it is not broadcast packet already. The router must
3165 broadcast to inform other routers about changed ID.
3167 * Added backpointer to server's router into SilcServer context in
3168 silcd/server_internal.h.
3170 * Fixed silc_server_packet_broadcast to send correct broadcast
3173 * The channel key is now distributed to the local client as soon
3174 as it is received from the router (in router environment) so that
3175 no other packet may be sent for the channel until client has
3178 * silc_server_remove_channel_user now broadcasts the received
3179 Remove Channel User packet if it is not broadcast packet already.
3180 The router must broadcast to inform other routers about removed
3183 * Added users field into SilcPacketContext that is a reference count
3184 of the context. One can increase the reference count by calling
3185 silc_packet_context_dup which is now changed to just increase the
3186 reference count instead of duplicating the data. The reference
3187 count is decresed by calling silc_packet_context_free that will
3188 free the data after the reference count hits zero.
3190 For now on the packet context and everything allocated into it
3191 (including the raw packet from network) must be freed by calling
3192 the new silc_packet_context_free function. Added also new function
3193 silc_packet_context_alloc that must be used now to allocate the
3194 context. This also means that if a routine is asynchronous from
3195 silc_[client/server]_packet_parse_type the packet context must
3196 be duplicated by calling silc_packet_context_dup. Otherwise it
3197 gets free'd after silc_[client/server]_packet_parse_type returns.
3198 Also, one must remember that if packet is duplicated then its
3199 reference count must be decresed by calling the free function as
3200 many times as it was duplicated.
3202 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3203 from both client and server.
3205 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3207 * Made joining to a channel working in router environment.
3209 * Cleaned up JOIN command on server side and create function
3210 silc_server_command_join_channel internal routine to make the
3213 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3215 * Changed silc_command_pending list to SilcDList. Also, added
3216 `ident' field to SilcServerCommandPending structure to identify
3217 the reply and to call correct callback.
3219 Added silc_server_command_pending_check function to replace the
3220 corresnponding macro. The silc_command_pending list is not
3223 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3224 to set identifier to previously allocated Command Payload. It
3225 is used to set identifier for command when resending Command
3228 * Added silc_command_payload_encode_payload to encode Command
3229 Payload buffer from SilcCommandPayload structure.
3231 * Added silc_argument_payload_encode_payload to encode Argument
3232 payload buffer from SilcArgumentPayload structure.
3234 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3236 * Changed WHOIS command to support router connection on server side.
3237 The whois request is always sent to router unless the server is
3238 standalone server. After server has received the reply from the
3239 router will it send the reply to the client.
3241 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3242 broadcast received broadcast packet. The function is used only
3243 by router. The broadcast packet is always sent to the router's
3246 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3247 render given ID to printable string, for log files for example.
3249 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3251 * Made basic router to router connections working. At least they
3252 can now connect to each other but nothing really works the way
3253 they are supposed - yet.
3255 * Added new initiator token to RouterConnection configuration
3256 file in silcd/serverconfig.[ch]. It is used to tell whether we
3257 are the initiator to the remote router or whether we'll expect
3258 the other end to connect.
3260 * Moved registering of listener task to silc_server_init, hence
3261 the server starts listenning as soon as it is run, even if it
3262 does not have connections to other routers. Let's see how well
3265 * Changed default connection retry timeouts for more suitable in
3268 * Removed cipher and such arguments from silc_idlist_add_client
3269 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3270 Added new function silc_idlist_add_data to add the keys and stuff
3273 * Added SilcIDListData structure and added it to SilcClientEntry
3274 and SilcServerEntry as their first field in the structure. This
3275 way we can explicitly cast the ID entries to the SilcIDListData
3276 structure and get common data for the entries. In past, we had
3277 to first check what type of connection it is and then cast it to
3278 correct ID entry type. Now, we can directly cast the opaque
3279 pointer to the SilcIDListData (no matter what ID entry it actually
3280 is) and get the data needed.
3282 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3285 in some circumstances even if threre were timeout tasks, though not
3286 IO tasks, but tasks anyway. Now fixed.
3288 * Defined SilcServerConnection structure to hold connection specific
3289 stuff about directly connected servers and routers. The definition
3290 is currently in silcd/server_internal.h. I thought about having
3291 a bit more important role fro this struct but for now it is used
3292 only when connecting to other server (or router actually).
3294 * Added connecting retry support in server when connecting to
3295 router(s). The retry feature implement exponential backoff
3296 algorithm. Also, added SilcServerParams structure to hold default
3297 parameters for server. For now, it include these retry settings
3298 and are hard coded. After server is moded to be as Silc Server
3299 Library this structure will be more important.
3301 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Changed client librarys channel->clients table to SilcList and
3304 changed code accordingly.
3306 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3308 * Changed client's channel table to SilcList and changed code
3309 accordingly. Also changed SilcChannelClientEntry to include back-
3310 pointer to the channel so that client entry can use that structure
3311 as list as well and we have fast cross-reference to the channel.
3312 This change dramatically decreased the complexity of channel
3313 handling with client entry and vice versa (removed one extra
3314 loop when searching for channel entry from many functions).
3316 * Changed server->sim from table to SilcDList and changed code
3319 * NAMES command can now be used from user interface. It will show
3320 the user list on the channel, neatly.
3322 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3323 Code now saves realname of the user if it becomes available.
3325 * Renamed configure.in to configure.in.pre and made ./prepare
3326 script to automatically add correct version string to
3327 configure.in which it creates from configure.in.pre.
3329 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3331 * NAMES command reply now shows users mode with the nickname when
3334 * Moved silc_client_ch[u]mode[_char] functions from
3335 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3336 place sucks, they are utility functions and should be in some
3339 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3341 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3344 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Added TRQ (efficient deque and list library) into lib/trq. This is
3349 a very good list library that is currently used in the SILC. Defined
3350 SilcList API over the library because I didn't like the API very
3351 much. See lib/trq/silclist.h for the API and examples of how to
3352 use the API. Fixed various places in the code to use the new
3353 SilcList API. The SilcList is meant for lists that has a structure
3354 already defined as a list. It is not suitable to add just some
3355 context to the list (in TRQ, the context is the list actually).
3357 So, I defined SilcDList that can be used for the purpose where
3358 predefined list structure does not exit. This can be used as
3359 such list. Now some context just can be added to the SilcDList.
3360 Currently this list is not used in the SILC just yet, though there
3361 are a lot places where this can replace dynamically allocated
3362 tables and I will fix these places, later, to use SilcDList.
3363 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3364 and use TRQ internally).
3366 Also fixed some annoying warning messages that the original TRQ
3367 code generated. Also minor changes to TRQ's Makefile.in.
3369 * Added support for querying by Client ID to both WHOIS and
3370 IDENTIFY commands into server, as required by the protocol.
3372 * Removed method function pointers from SilcBuffer structure. They
3373 weren't used to anything and just increased the context size for
3374 no good reason. This change also made silc_buffer_alloc and
3375 silc_buffer_free functions inline functions.
3377 * Disabled command flooding detection support until it's fixed so
3378 that it accepts commands in but does not execute them more than once
3381 * Added silc_net_localhost(), to return local hostname, into
3382 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3383 that must be initialized before calling silc_client_init.
3385 * Added new function: silc_server_send_notify_on_channels to send
3386 notify messages to all channels client has joined. It is assured
3387 that the message is sent only once per client.
3389 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3390 lib/silcutil/silcutil.[ch] as silc_format function. The new
3391 function is generic and is used by server as well, not only by
3392 the logging routines.
3394 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3395 the provided version string was not acceptable. Added new function:
3396 silc_ske_check_version into lib/silcske/silcske.h. The function
3397 must be implemented by the application (client or server) and it
3398 does not reside in the SKE library. The function checks the version
3399 string remote end sent.
3401 * Added back pointers (to opaque context and to SilcSocketConnection)
3402 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3404 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3405 duplicate packet context structure.
3407 * Changed `notify' client operation to send same arguments as client
3408 receives from server except for ID's. ID's are mapped to correct
3409 ID entry and that is returned. Also, if channel entry is not sent
3410 by server but the notify is for channel the channel entry is sent
3411 to application (otherwise application doesn't know that it is for
3412 channel (library gets it from packet's Destination ID)).
3414 * Added silc_client_remove_from_channels into client library to
3415 remove a client from all channels it has joined to. Used when
3416 received SIGNOFF notify from server. Added also new function
3417 silc_client_replace_from_channels to replace old ID entry with
3418 new ID entry on all channels. Used when received NICK_CHANGE
3421 * Fixed ID Cache list handling in silc_idlist_get_client in
3422 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3423 to get (or query) client by ID.
3425 * Updated TODO list.
3427 * Added connection authentication status message defined by the
3428 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3429 support for these into the code in client and server side.
3431 * Added generic function silc_client_send_command to send any command
3432 with variable argument list. Application should use this function
3433 to send commands if the command functions provided by the library
3434 does not suite for the application's user interface needs.
3436 * Added new `failure' client operation. Application is notified about
3437 received failure packet if client is executing a protocol. In this
3438 case the protocol's execution has failed.
3440 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3441 is required by the protocol.
3443 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3444 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3447 * Added status flag to SilcSKE object to indicate realtime status
3448 of the SKE protocol.
3450 * Application receives now exactly same command reply arguments as
3451 the library receives from server. However, if ID is received the
3452 corresponding ID entry is returned to the application (eg. Client
3453 ID is mapped to correct SilcClientEntry entry and that is returned).
3454 Changed command_reply client operation due to this change.
3456 * Changed all ID's in commands and in command replys as ID Payloads.
3457 Change affected both client and server side codes.
3459 All ID's sent in SILC network (with execption of ID's in SILC
3460 Packet header) are sent in ID Payload to support variable length
3463 * Server now notifies nick changes and notifies all clients on
3464 the channels about the new nickname (about the new Client ID,
3467 * Implemented CMODE command to change channel modes. Supports all
3468 channel modes defined by the protocol specs except ban and invite
3469 lists. (Also, private channel key mode is supported but support for
3470 setting private channel key in client is missing, thus, this mode
3471 has no effect on client side (except that server requires that the
3472 client uses private channel key and normal channel traffic does not
3475 Also, invite mode works per se, but INVITE command does not work
3476 yet correctly, so you can set channel as invite only channel but
3477 inviting clients to the channel does not work (it is yet to be
3478 thought what's the best way to do it).
3480 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3481 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3482 Implemented CUMODE command to change user's mode on the channel.
3483 Supports all modes defined by the protocol specs.
3485 * Added NAMES command reply to return users modes on the channel.
3487 * Removed unnecessary and slow ciphers from lib/silccrypt.
3489 * Set SO_KEEPALIVE option to connection sockets by default.
3491 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3493 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3494 redefined the Notify Payload into protocol specs.
3496 * Added silc_id_payload_parse_id to get ID directly from raw
3499 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3502 accept searching by Client ID as well.
3504 * Added support for LEAVE and SIGNOFF notify types in client library.
3506 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3507 to parse ID Payload from raw data.
3509 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * Added flags parameter into silc_ske_assemble_security_properties
3512 function in lib/silcske/silcske.[ch].
3514 * Changed notify client operation to fit better for notify messages
3515 sent by server. The notify payload received from server is now
3516 passed to the application (after parsing it to SilcNotifyPayload).
3517 It is application's responsibility to retrieve the arguments
3518 from the payload and show the message the way it wants. The message
3519 sent by server is implementation specific.
3521 * Changed public keys to comply with the protocol specification.
3522 Old public keys are not supported anymore and are not compatible.
3524 * Removed nickname from Channel Payload as the latest draft removed
3525 it. The client must resolve the nickname from the NAMES command
3526 reply received when it joined the channel.
3528 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3530 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * Fixed some errors in protocol specification drafts.
3534 * Created lib/silccore/silcnotify.c to implement Notify Payload
3535 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3536 generic payloads described by protocol specifications. The file
3537 includes implementations for ID Payload and Argument Payload.
3539 * Changed Command Payload implementation to use the new Argument
3540 Payload. Changed command_xxxx_payload to command_payload_xxxx
3541 to comply with SILC coding conventions.
3543 * Added suppport for Argument Payload handling in Notify Payload
3544 implementation as protocol requires it. Added the new support
3545 into server and client lib as well.
3547 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3549 * Added support for multiple nicknames on same channel. [n] is
3550 added locally to the nickname if there are more than one same
3551 nicknames on the channel.
3553 * Server now sends all nicknames that matched WHOIS request.
3554 Client also shows the list received from server.
3556 * Added TOPIC command to client side. User can now set and show
3557 current topic on channel.
3559 * Added MOTD command to client and server. Also, server sends the
3560 motd when client connects to the server.
3562 * Changed version strings to comply ISO 8601.
3564 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Fixed protocol error handling in client library. It should now
3567 cope even if the SKE fails for some reason.
3569 * Made new protocol specification drafts for submitting to IETF.
3571 * Implemented TOPIC command to server in silcd/command.c.
3573 * Added two new notify types into lib/silccore/silcnotify.h:
3574 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3575 notify nickname change and topic setting/change on a channel.
3577 * API change of command_reply operation in client library. The
3578 application gets now the status type received from server as well.
3580 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3584 * Cras fixed and optimized the packet handling even further and
3585 it should work now. Minor change to the prototype of function
3586 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3588 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3590 * Added new function into lib/silcutil/silcschedule.[ch]:
3591 silc_schedule_with_fd to select() a specified fd. The function
3592 returns after timeout expires or data arrives or goes. The
3593 function is used by packet routines to wait that all data is
3594 received from network.
3596 * Fixed data reading from network in lib/silccore/silcpacket.c.
3597 The code now assures that all data is read from the fd and then
3598 continues packet processing. This was a bug fix since the code
3599 used to drop some data in some circumstances.
3601 * Added new function into lib/silcclient/client.[ch]:
3602 silc_client_start_key_exchange to start key exchange after
3603 connection has been established to server. The code internally
3604 now uses this funtion but its main purpose was to provide it
3605 for applications that perform their own connecting. After
3606 application has created a connection it merely calls this
3607 function to start the key exchange between client and server.
3608 The library takes care of everything else after that.
3610 Updated also lib/silcclient/README to explain the usage of
3613 * Do not send to application information that connection has
3614 been established. Application gets notified it by connect
3617 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3619 * Applied cras's patch to add silc_schedule_one function. The
3620 function runs scheduler once and returns.
3622 * Fixed the scheduler after cras messed it up. The timeout
3623 handling works now as it's supposed to work.
3625 * Added into lib/silccore/ silcnotify.h to include notify
3626 message types support. Changed silc_server_send_notify*
3627 functions, in server.[ch], to support those new notify types.
3628 Added the support for the notify types into client library,
3629 as well. Added new notify client operation into ops.h in
3632 * Changed silc_server_packet_send_to_channel to send normal
3633 packets instead of just channel message packets. The function
3634 is now used to send the notify packets to channels. It is not
3635 used to send channel message packets anymore, as server never
3638 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3639 va_arg()s as it seems to require it nowadays. I guess, if SILC
3640 is compiled with older va_arg() the new code should work anyway.
3642 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3644 * Splitted core library. Core library (lib/silccore) includes
3645 now only SILC protocol specific core (and common) components.
3646 Created new utility library (lib/silcutil) that includes more
3647 generic purpose stuff. The stuff for util library was taken
3648 from the old core library. This was minor and easy split.
3650 * Created SILC Client Library (lib/silcclient) that includes
3651 implementation of the SILC client without user interface. This
3652 was major move from silc/ directory. The code has been changed
3653 so that it is transparent towards the user interface. The
3654 silc/ directory includes now the same user interface as before
3655 and it uses the new client library. Read lib/silcclient/README.
3656 Basicly, the client library performs everything else related
3657 to SILC except user interface handling. Also, configuration
3658 files are considered to be part of user interface and library
3659 does not handle them.
3661 This change also changed a lot of structures, function naming etc.
3662 Most important change was that SilcClientWindow object was
3663 renamed to SilcClientConnection in the client library. Created
3664 also new file lib/silcclient/ops.h. Also added new files
3665 silc/local_command.[ch] and silc/client_ops.[ch].
3667 All these changes were made to make it easier for user interface
3668 designers to create what ever user interface for the SILC client
3671 It is also expected that the server will be moved to lib
3672 directory as well and SILC Server Library will be created;
3673 sometimes in the future.
3675 * Removed Local commands from lib/silccore/silccommand.h as
3676 they are application specific and new client library does not
3677 handle any of those anymore.
3679 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3680 old client implementation in silc/.
3682 * Added support for callback functions in SILC_LOG_* macros.
3683 Application can now set its own callbacks that will be called
3684 instead of using the default functions that will always print
3685 the debug messages to stderr (or stdout). Also, debugging can
3686 now be disabled by setting silc_debug to FALSE and re-enabled by
3687 setting it to TRUE. Note, that logging will still work even
3688 if debugging is disabled.
3690 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3691 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3692 silc_log_reset_debug_callbacks.
3694 * To enable debugging in silc client one must give now -d
3695 option on command line.
3697 * Changed silc_schedule_init to automatically allocate task queues
3698 if they are not allocated before calling it.
3700 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Added GMP 3.1 into math library.
3704 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3706 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3707 a channel in SILC network. The packet is used by servers and
3708 routers to notify other routers that user has left a channel.
3709 This little feature was missing until now. Added the feature
3710 to protocol specification as well.
3712 Added functions: silc_server_send_remove_channel_user and
3713 silc_server_remove_channel_user into server.[ch].
3715 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3716 lib/silccore/silcpacket.h. However, they are not implemented
3719 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3721 * Fixed joining to a channel and sending channel messages
3722 between server and router. The channel message sending should
3723 now work inside a cell.
3725 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Fixed the private message sending between server and router.
3728 The private message sending should now work inside a cell.
3730 * Added silc_server_replace_id into server.[ch] to replace
3731 existing ID in the SILC network.
3733 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3734 and silc_idlist_replace_server_id into idlist.[ch] in server.
3736 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Fixed the server to server connections. Server can again now
3739 connect to router. Router to router connections probably does
3742 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Added dynamic protocol registering support. Now protocols can
3745 registered and unregistered on the fly. Patch by cras.
3747 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Added lib/contrib directory to hold routines that some platforms
3750 don't have but are needed by SILC.
3752 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3753 into lin/contrib to provide getopt() and getopt_long() for
3754 those who don't have it.
3756 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Added AWAY command to client. When away message is set and
3759 client receives a private message packet the client automatically
3760 replies to the sender with the away message.
3762 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3763 bug seemed to be the cause of recent problems when compiling
3766 * Added version detection support to SKE protocol specification
3767 and added the new changes to the SKE implementation as well.
3768 There were other minor changes in the SKE protocol as well.
3770 Many changes in lib/silcske/silcske.[ch] and in
3771 lib/silcske/payload.[ch].
3773 * Added ^U functionality, clear input line. Patch from cras.
3775 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3777 * Mainly small bugfixes on core library. Fixed some debugging
3778 logging and buffer overflow in silclog.c.
3780 * Updated config.sub and config.guess on the distribution tree.
3782 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3784 * Added command lagging support in server. Client may execute
3785 commands now only once in two seconds.
3787 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Optimized packet reception. MAC computation and checking is now
3790 also more optimized. A lot previously duplicated code is now
3791 used as generic by both client and server.
3793 * Fixed key pair generation in clientutil.c
3795 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Added into lib/silccore/silcbufutil.[ch] new function;
3798 silc_buffer_realloc.
3800 * Moved generic packet sending/encryption functions to
3801 lib/silccore/silcpacket.[ch] from client and server. Some
3802 rewriting of the functions.
3804 * Moved all generic packet reception/decryption functions to
3805 lib/silccore/silcpacket.[ch] from client and server. The
3806 packet processing is now much cleaner in both client and server.
3807 These were major changes in both client and server.
3809 * Created many common functions in server to do packet sending.
3810 Previously code were duplicated a lot, this has been removed
3813 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Rewrote major parts of the ID cache system. Don't know
3816 whether it is better now or not but at least the API is more
3819 * Major rewrite on ID cache stuff on client because of the ID
3820 cache API changes. Added idlist.c to client.
3822 * Also major rewrite on ID cache stuff on server as well.
3823 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3824 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3825 in hand, instead they are all put into the ID cache system now.
3826 All server_idlist_* routines uses ID cache now instead of
3827 traversing its own lists (those lists does not exist anymore).
3828 SilcIDList though still exists. Also, SilcXXXEntry's are
3831 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Finally made the SKE implementation compliant to the protocol
3834 specification. All mp integers are now binary encoded as
3835 opposed being HEX encoded.
3837 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3840 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3841 functions: silc_[encode/decode]_pem. Also added function
3842 silc_encode_pem_file to PEM encode with newlines ('\n') for
3845 * SILC public keys are now encoded either PEM or binary. Same
3846 option is for private keys as well. By default private keys
3847 are binary encoded and public keys PEM encoded. Silly HEX
3848 encoding were removed.
3850 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3851 function to create fingerprints.
3853 * Fixed a bug in SHA1; does not change the original data anymore.
3855 * Partly implemented INFO command on client and server side.
3856 Fixed CLEAR command. Changes to SERVER command; show current
3857 server(s) when giving command without arguments. Added
3858 VERSION command to client.
3860 * Added check to server that unregistered connections cannot
3861 execute commands (unless it is specificly allowed).
3863 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * Fixed screen refresh.
3867 * Fixed channel joining bug from client. On some circumstances
3868 client tried to join to a channel it had already joined.
3870 * Added public key verification process into client's protocol.c.
3871 The client now verifies the public key from user and saves
3872 it into ~./silc/serverkeys/ directory.
3874 Added into: clientutil.[ch]: silc_client_verify_server_key.
3876 * Changed SKE protocol's silc_ske_initiator_finish function
3877 to accept callback function that verifies the received public
3878 key. Removed old silc_ske_verify_public_key function.
3880 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3883 silc_pkcs_private_key[_data]_set.
3885 * Made the password and public authentication more cleaner in
3886 server's protocol.c.
3888 * Removed historic and obsolete protocol `channel_auth' from
3889 both client and server.
3891 * Removed wrong way of sending command status messages from
3892 server to client in server's command.c. The old way violated
3893 protocol specification.
3895 Changes to silccore/silccommand.[ch]: removed
3896 silc_command_encode_status_payload -> not needed anymore,
3897 changed silc_command_encode_payload_va to accept extra
3898 argument on variable argument list. The argument type must
3899 now be provided to the function. Also, added new function:
3900 silc_command_encode_reply_payload_va which is same as
3901 normal command_encode_payload_va except command status type
3902 is provided as extra argument.
3904 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3906 * Added ~./silc directory handling. The directory includes the
3907 public and private keys for the client.
3909 Added silc_client_check_silc_dir, silc_client_create_identifier
3910 and silc_client_load_keys.
3912 * Implemented SILC protocol compliant public key. Added public
3913 and private key saving to and loading from files.
3915 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3916 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3917 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3918 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3919 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.

3926 * Added silc_server_get_route (route.[ch]) to get connection
3927 data for the fastest route for given ID.

3930 were re-defined in the SILC Protocol Specification and the
3931 implementation now complies with the specification.
3933 * Implemented PING command on client and server.
3935 * Implemented NAMES command on client and server. The server side

3949 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3950 was tested. SOCKS4 was not but should work anyway.
