1 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added Makefile.defines[.in] that should for now on be included
4 in all Makefile.am file in the source tree. That file includes
5 all common compilation definitions for SILC source tree. Also
6 all external packages that has been included in the SILC source
7 may include it (like irssi for example) to use the SILC defaults.
9 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
11 * Minor changes to the ./prepare script to change the package
12 name according the distribution name to the configure.in.
14 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
16 * Created new distribution system. Added file `distributions'
17 that defines all the distributions that can be created out of
18 the SILC source tree. The ./prepare script now reads that
19 file to determine how to prepare the distributions. The
20 first argument to the ./prepare is the name of the distribution
21 and second is the version of the distribution. If given
22 without arguments it creates the default (toolkit) distribution
23 with the default version (defined in ./prepare).
25 All Makefile.am files that are subject to the distributions
26 are now named as Makefile.am.pre. These are ./Makefile.am
27 and lib/Makefile.am. Others may be changed later.
29 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
31 * Added invite list, ban list, some key management and connection
32 error message printing to module formats in the Irssi SILC client.
34 * Added new silc_client_set_away_message to set the away message
35 that is back to the person who sent private message. The
36 affected file lib/silcclient/silcapi.h and the
37 lib/silcclient/client_prvmsg.c.
39 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
41 * Fixed the private message sending in the Irssi SILC client,
42 added local command KEY to the Irssi SILC client.
44 Added key management and key agreement message formats to the
45 irssi/src/fe-common/silc/module-formats.[ch].
47 Added USERS (alias WHO) printing, server/router operator
48 indication and LIST command printing to the module formats.
50 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
52 * Fixed channel joining notify handling, cumode notify handling
53 from Irssi SILC client.
55 * Added SILC specific module-formats to the Irssi SILC client so
56 that SILC specific message hilighting, colors etc is possible.
57 Affected file irssi/src/fe-common/silc/module-formats.[ch].
59 Added channel mode, channel user mode, actions, notices,
60 whois and whowas printing to the the module-formats.c.
62 * Fixed a bug in channel deletion in the server. The channel
63 is not left to the cache even if the channel founder auth mode
64 is set when there are no users anymore on the channel. Affected
67 * The silc_net_localhost now resolves the entire hostname including
68 the domain name. Affected file lib/silcutil/silcnet.c.
70 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
72 * Changed the ask_passphrase client operation to be ascynchronous.
73 It has now a completion callback and a context that the
74 application must call after it has got the passphrase from
75 the user. Affected files lib/silcclient/silcapi.h,
76 lib/silcclient/protocol.c, lib/silcclient/command.c and
79 Added SilcAskPassphrase callback that the application calls
80 to deliver the passphrase to the library.
82 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
83 The public key verification and especially a certificate
84 verification is asynchronous procedure.
86 Added new SILC_SKE_STATUS_PENDING status to indicate the
87 request is pending and a callback will be called to finalize
90 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
91 indicate that remote end did not send its public key (or
92 certificate), even though we require it. Added check for this
93 condition in the SKE. This was a security bug, now fixed.
95 Defined new SilcSKEVerifyCbCompletion callback that is called
96 when the verification process is completed.
98 The affected files lib/silcske/silcske_status.h and
99 lib/silcske/silcske.[ch].
101 * Changed the verify_public_key client operation to be async
102 as well. Defined SilcVerifyPublicKey callback that is used to
103 indicate the success of the public key verification process.
105 Changed the server and client to use the new async client
108 * Changed the Irssi SILC client's internal scheduler to be called
109 twice as many times as it used to be. As a result the client
110 should be a bit faster now. Affected file is
111 irssi/src/silc/core/silc-core.c.
113 * Added support to Irssi SILC client of asynchronous public key
114 verification and passphrase inquiry. Affected file is
115 irssi/src/silc/core/silc-core.c.
117 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
119 * Do not say "You have left channel %s" in client library.
120 Moved it to the application. Affected files are
121 lib/silcclient/command.c and silc/client_ops.c.
123 * Fixed silc_client_get_clients. Command context was not
124 duplicated and was freed memory in the callback. Affected
125 file lib/silcclient/idlist.c.
127 * Do not say "you are now talking..." on JOIN command in the
128 client library. The appliation must handle it.
130 * Do not say ".. changed topic to" in command reply in the
131 client libary. The application must handle it.
133 * Fixed TOPIC command sending in the client library.
135 * Fixed a memory leak in silc_client_command_free in the file
136 lib/silcclient/command.c.
138 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
140 * Imported a modified version of Irssi client to the source tree.
141 The Irssi will be used to create a new client called
142 Irssi SILC. Imported to irssi/.
144 Added silc_core_init_finish function to the Irssi. Affected
145 file irssi/configure.in.
147 A lot changes in the Makefile.ams around the irssi tree.
149 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
151 * Do not rehash if the new size is same as the old size of the
152 hash table, in the silc_hash_table_rehash*. The affected file
153 lib/silcutil/silchashtable.c.
155 * Replaced hash_table_del_by_context calls from the server
156 (when channel->user_list and client->channels) to the
157 hash_table_del as it is sufficient and faster.
159 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
161 * Added silc_hash_table_list, silc_hash_table_get and the
162 SilcHashTableList structure to provide an alternative way to
163 traverse the hash table. The affected files are
164 lib/silcutil/silchashtable.[ch].
166 * Changed the server's idlist routines to use the hash table
167 routines to optimize the code.
169 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
171 * Replaced the client entry's `channel' list and channel entry's
172 `user_list' list to hash tables for optimized lookup. Changed
173 the code to use the hash table interface around the code.
174 Affected file lib/silcd/idlist.[ch].
176 * Added `auto_rehash' boolean argument to the function
177 silc_hash_table_alloc to indicate whether the hash table should
178 auto-rehash when it thinks is appropriate time. It will
179 increase the hash table size if the there is twice as much
180 entries in the table than the size of the table, and will
181 decrease the size if there are twice as less entries than
182 the size of the table.
184 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
186 * Fixed silc_xxx_get_supported to not crash at some circumstances.
188 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
190 * silc_idcache_purge_by_context deletes the entry now by context
191 as it is supposed to do. Affected file lib/silccore/idcache.c.
193 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
194 client is not anymore valid (WHOWAS givens the info) and not
195 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
197 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
199 * Removed the `data' and `data_len' arguments from the ID Cache
200 interfaces and added `name' argument. ID Cache does not handle
201 anymore the binary data only a names associated with given ID.
203 * When hashing a Client ID with silc_hash_id the entire ID is
204 not hashed anymore, instead only the hash of the Client ID is
205 hashed. This way we can access the Client ID from the cache
206 with Client ID but with the hash of the ID (which is a hash of
207 the nickname) as well without any difference in performance.
209 Added also silc_idcache_find_by_id_one_ext to do one on one
210 searching when we have the actual ID. Added also function
211 silc_hash_client_id_compare. The affected files are
212 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
214 * When hashing the name associated with a ID it is always done
215 in lowercase. This way we can access the cache without worrying
216 about case-sensitivity, even though, for example nicknames are
219 * Fixed a bug in server with channel message sending. It put
220 wrong ID type as destination ID. The affected file
223 * silc_idcache_del_by_context now deletes from all hash tables
224 by context. Affected file lib/silccore/idcache.c.
226 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
228 * Changed the client library to use the new ID Cache interface.
229 Changes around the source tree.
231 * Added silc_hash_table_rehash_ext to rehash with specific
232 hash function. Affected file lib/silcutil/silchashtable.[ch].
234 * Added silc_hash_string_compare to compare two strings in the
235 hash table. Affected file lib/silcutil/silcutil.[ch].
237 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
239 * Added new function silc_idcache_del_by_context into the
240 lib/silccore/idcache.[ch].
242 * Changed the server's ID list routines to use the new ID Cache
243 interface. Changes around the source tree.
245 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
247 * Added silc_hash_table_del[_by_context]_ext functions in to the
248 lib/silcutil/silchashtable.[ch].
250 Removed silc_hash_table_find_all* routines and added new
251 silc_hash_table_find_foreach to replace them.
253 Added silc_hash_table_replace_ext function as extended
254 replacing function. Separated the simple hash table interface
255 from the extended hash table interface in the file
256 lib/silcutil/silchashtable.h.
258 * Fixed minor bugs and changed it to use some of the new
259 hash table functions in lib/silccore/idcache.c
261 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
263 * Added new function silc_hash_table_find_all to return all keys
264 in the hash table by the specified key. As the hash table is
265 collision resistant it also makes it possible to have several
266 duplicate keys in the hash table. This function may be used to
267 find all of the keys from the hash.
269 Added user_context arguments to the SilcHashFunction,
270 SilcHashCompare and SilcHashDestructor to deliver user specified
273 Added new fuctions silc_hash_table_find[_all]_ext to do
274 extended lookup with specified hash and compare functions and
275 specified user contexts.
277 Added new function silc_hash_table_add_ext to add the key
278 with specified hash function and user context.
280 Added new function silc_hash_table_foreach to traverse all
281 entrys in the hash table. Added SilcHashForeach callback
284 Added new function silc_hash_table_del_by_context to delete
285 the entry only if the context associated with the key matches.
287 Affected files are lib/silcutil/silchashtable.[ch].
289 * Removed silc_hash_[server/client/channel]_id and added just
290 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
291 silc_hash_id_compare to compare two ID's using as the hash table
292 comparison function. Added also silc_hash_data to hash
293 binary data and silc_hash_data_compare to compare it.
295 * Removed silc_idlist_find_client_by_hash as it is not needed
296 anymore. Affected file silcd/idlist.[ch].
298 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
299 to use internally the SilcHashTable. The new ID Cache is a lot
300 faster than the old one. Some of the ID Cache interface was also
301 rewritten and obsolete and stupid functions were removed.
303 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
305 * Added entry_count field to the SilcHashTable to keep the number
306 of the entries in the table. Implemented the function
307 silc_hash_table_rehash. Added new function
308 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
310 Fixed a minor bug in silc_hash_table_free.
312 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
313 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
314 into the lib/silcutil/silcutil.[ch].
316 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * Implemented a collision resistant hash table into the
319 lib/silcutil/silchashtable[ch]. See the header and the source
320 for the SilcHashTable API.
322 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
324 * Merged dotconf version 1.0.2 into lib/dotconf.
326 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
328 * Do not compile anything in lib/silcsim/* if the SIM support
329 is not enabled. The tree should now compile without problems
332 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
334 * Compiled the SILC under cygwin. Compiled and tested briefly
335 without problems. More tests needed. The SIMs didn't compile
338 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
340 * Fixed possible crash in silc_get_username in the
341 lib/silcutil/silcutil.c.
343 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
345 * Fixed a va_arg in silc/client_ops.c.
347 * Oops, RC5 routines were named AES and caused some problems
348 when not using SIM's. Affected file lib/silccrypt/rc5.c.
350 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
352 * Added new SilcIDIP structure into the lib/silccore/id.h and
353 replaced the old `ip' fields from all SILC ID's to that type.
354 This is a step towards IPv6 support.
356 The silc_id_get_len takes now the ID as an extra argument.
357 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
358 both IPv4 and IPv6 based ID's.
360 The affected files are lib/silccore/id.[ch] and other files
361 around the tree using these routines.
363 * Removed the ID length arguments in server from various
364 silc_server_send_notify_* routines -> they are not needed
367 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
369 * Fixed memory leak in silc_encode_pem_file in the file
370 lib/silcutil/silcutil.c.
372 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
374 * Check minor version as well in the SKE. Affected files are
375 silcd/protocol.c and lib/silcclient/protocol.c.
377 * Added --identifier option to the server so that an identifier
378 can be when creating the public key for the server. Affected
379 file is silcd/silcd.c.
381 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
382 lib/silccrypt/silcpkcs.c.
384 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
386 * Register default ciphers and stuff when using -C option with
387 the server. Affected file sildc/silcd.c.
389 * Put back the servers public key filename format, it is better
390 than the new one. For now, the client keys are saved with the
391 new filename format. The affected file silc/client_ops.c.
393 * Implemented the Cipher API for the rest of the ciphers that
394 did not implement it or implemented it the wrong way.
396 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
398 * Register default ciphers and stuff when using the -S option
399 in the client. Affected file silc/silc.c. Same also when
400 creating new key pair with -C option.
402 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
404 * Fixed the silc_verify_public_key client operation function to
405 save the public keys differently. The fingerprint is now
406 used as filename and not the hostname. This way also the
407 client keys are saved uniquely and not with hostnames. The
408 affected file is silc/client_ops.c.
410 * Trimmed the silc_hash_fingerprint function to remove extra
411 whitespaces from the end of the fingerprint. The affected
412 file is lib/silccrypt/silchash.c.
416 * Added silc_cipher_register_default function to register all
417 default ciphers. It can be used when configuration files
418 does not exist and the application does not want any specific
419 ciphers in any specific order.
421 The SilcDList is now used as silc_cipher_list dynamically
422 allocated cipher list. Removed the static list all together
423 and now all ciphers must be allocated to the dynamic list.
424 The silc_cipher_alloc routine was changed to check only the
427 All silc_cipher_* routines that used to return int returns
430 The affected files lib/silccrypt/silccrypt.[ch].
432 * The same thing was done to silc_hash_* as for silc_cipher_*
433 routines. Affected files lib/silccrypt/silchash.[ch].
435 * The same thing was done to silc_pkcs_* as for silc_cipher_*
436 routines. Affected files lib/silccrypt/silcpkcs.[ch].
437 Added also silc_pkcs_[un]register[_default] functions.
438 Removed the data_context from the PKCS API.
440 * Added silc_hmac_register_default function to register default
441 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
442 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
443 to unregister all hmacs at once.
445 * Register the default ciphers, hash functions, PKCSs and HMACs
446 if client's configuration file does not exist. The affected
449 * The client did not load the hash functions from the SIM
450 modules at all. Added support for this. Affected file is
453 * When decoding public key with silc_pkcs_public_key_decode, check
454 the supported algorithm only if PKCS are registered. Affected
455 file lib/silccrypt/silcpkcs.c. The same was done with the
456 silc_pkcs_private_key_decode.
458 * Fixed the SILC List routines to keep the list always in order.
459 It used to change the list's order when traversing the list but
460 not it preserves the order. Affected file lib/trq/silclist.h.
462 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
464 * Added the client library to use the SilcSocketConnection's
465 reference counter (by silc_socket_dup) to prevent the bug that
466 the socket object may be freed underneath async operation.
468 * The name resolv library checking fixes in the configure.in.pre.
471 * Created new version of the protocol drafts for future
472 development. The -03 drafts are the ones that will be changed
473 in the trunk now and the -02 will remain as they are.
475 * Send list of CUMODE notifys to the router when announcing
476 the channel users to the router. Affected file silcd/server.c.
477 If the router receiving channel founder CUMODE for a channel
478 that already has channel founder it will send CUMODE notify
479 to the sender to remove the channel founder rights from the
480 announced client. Affected file silcd/packet_receive.c.
482 * The CUMODE notify may now use Server ID as well as the entity
483 who changes the mode. Updated protocool specs.
485 * Updated INSTALL and README files.
487 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
489 * New web pages in the http://silc.pspt.fi. The pages was
494 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
496 * Implemented the [DenyConnectin] config section in the server.
497 Added silc_server_config_denied_conn to check whether incoming
498 connection is denied. Affected file silcd/serverconfig.[ch].
500 * Do not check the ports when checking the incoming configuration
501 data if the port is 0, meaning any. Affected file is
502 silcd/serverconfig.c.
504 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
506 * Fixed buffer overflow in silc_string_compare in the file
507 lib/silcutil/silcutil.c.
509 * Fixed double free in silc_server_command_leave in the file
512 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
514 * Fixed the version checking in the server. Affected file is
517 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
519 * Fixed the configuration data fetching when accepting new
520 connections in the server. Affected file silcd/server.c.
522 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
524 * Added `sender_entry' argument to the function
525 silc_server_packet_relay_to_channel so that we can check
526 whether some destination actually belongs to the same route
527 the sender belongs (ie, we must not resend the packet to the
528 sender). Affected file silcd/packet_send.[ch].
530 * Added `servername' field to the SilcClientEntry in the server
531 to hold the name of the server where client is from. Affected
532 file is silcd/idlist.h.
534 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Moved the channel message encrypting in the router betwen
537 router connections from silc_server_channel_message to the
538 silc_server_packet_relay_to_channel since we want to check
539 whether we have anybody channel before encrypting anything.
540 Affected files silcd/packet_[receive/send].c.
542 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
544 * Fixed the [AdminConnection] server config section to support
545 multiple entries. Affected file silcd/serverconfig.c.
547 * Added support into the server to check the validity of the
548 incoming connection before executing any KE or authentication
551 * The connection configuration is now saved to the KE and
552 connection auth protocol contexts and not fetched anymore in
553 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
555 * The local hosts listenning address and port is also resolved
556 now when starting the server. We want to have the socket object
557 to include the real address and port for the listener. Added
558 new function silc_net_check_local_by_sock into the files
559 lib/silcutil/silcnet.[ch].
561 * Fixed a broadcast bug in server -> do not broadcast if we
564 * Fixed a routing bug. Do not route broadcast packets ever.
565 Broadcast packets must be processed always and not routed since
566 they may be destined to some other host than yourself and thus
567 would get routed without no good reason. Affected file is
570 * Added function silc_server_config_is_primary_route to check
571 whether primary router connection has been configured (a router
572 configuration that we are initiating). If there is not, we
573 will assume that there is only two routers in the SILC network
574 and we will use the incoming router connection as our primary
575 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
577 * Changed the order of the broadcasting. Broadcast _after_ the
578 packet has been processed not before. Affected file is
581 * Fixed a [ClientConnection] parsing bug. The port was never
582 parsed correctly thus resulting to port 0. Affected file
583 silcd/serverconfig.c.
585 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
586 argument and did not set the broadcast packet flag. Affected
587 file silcd/packet_send.c. Fixed same bug in the function
588 silc_server_send_notify as well.
590 * If we receive NEW_ID packet for our own ID in the server, ignore
593 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
597 * Removed the nickname from the Private Message Payload.
598 Updated the code and the protocol specs.
600 * Updated protocol specs for submitting to the IETF.
602 * Tweaked the Random Number Generator a bit. Affected file
603 lib/silccrypt/silcrng.c. Exported a new function
604 silc_rng_[global]_add_noise which can be used to add more
607 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
609 * Do not parse packets with different timeout when protocol
610 is active -> may cause problem with rekey. Affected file
613 * When server receives signoff notify it must not create
614 new channel key if the client is on any channels since the
615 sender of the signoff notify will create it.
617 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Added printing of error messages during SKE protocol from the
620 failure packet sent by server during SKE. Affected file
623 * Removed the client's failure_callback handling with timeout
624 and handle it immediately when received.
626 * The SKE library returned wrong type in SUCCESS and FAILURE
627 packets. They must be 32 bit MSB not 16 bit MSB.
629 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Ok, rewrote the logic of the re-key and now it seems to work.
632 I tested it on high traffic with frequent re-keys without
633 problems. Added hmac_receive (and renamed hmac to hmac_send)
634 in SilcClientConnection in lib/silcclient/client.h and
635 in SilcIDListData in silcd/idlist.h. Also, removed the
636 SilcPacketParserContext's cipher and hmac fields as they are
637 not needed anymore and actually caused some problems when
638 the ciphers and hmac's changed underneath the packet parser.
640 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
642 * If re-key protocol is active then process the incoming packets
643 synchronously since we must assure that icoming packets encrypted
644 with the old key is processed before the new keys is set to
645 use. This is true other packets than for REKEY packets.
646 Affected file silcd/server.c. The same was done to client library
647 as well, affected file lib/silcclient/client.c.
649 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
651 * Fixed bug in client and server to accept the force send if
652 the packet is send from silc_[server/client]_packet_process
653 function. Otherwise the packets are never delivered, oops.
655 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
657 * Disable force sending of packets when REKEY protocol is active.
658 We must assure that no packet is sent directly when rekey is
659 performed. All packets must be sent through packet queue.
660 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
661 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
662 function is silc_[server/client]_packet_send_real to check
665 * Replaced the SIM paths from example config files to
666 /usr/local/modules. Also, make install creates now
667 /usr/local/silc/logs directory to hold all the SILC server
670 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
672 * Made the configure.in.pre work on Solaris. Patch by salo.
674 * Made all ciphers compatible with non-x86 machines. Defined
675 CBC mode macros into lib/silccrypt/ciphers_def.h.
677 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Fixed the make install.
681 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
683 * When MAC computation fails the silc_packet_decrypt returned 0
684 even though it was supposed to return -1. Fixed this. The
685 affected file is lib/silccore/silcpacket.c.
687 * Do not replace the config files in /etc/silc (in make install)
688 if they already exist. Affected file ./Makefile.am.
690 * Do not send re-key packets immediately but through packet queue.
691 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
693 * Changed silc_net_check_host_by_sock to return FALSE if the
694 IP/DNS could not be resolved. Though, it returns the IP address
695 now even if it could not resolve it (but returns also FALSE).
696 Affected file lib/silcutil/silcnet.[ch].
698 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
700 * Added silc_pkcs_decode_identifier to decode the public key's
701 identifier. Affected file lib/silccrypt/silpkcs.[ch].
702 Added also silc_pkcs_free_identifier. Added also new context
703 SilcPublicKeyIdentifier.
705 * Added -S option to the silc client. It is used to dump the
706 contents of the specified public key file.
708 * Changed the PKCS api to return the public key length when
709 setting the public key.
711 * Fixed a fatal bug in the public and private key file loading.
712 Affected file lib/silccrypt/silcpkcs.c.
714 * Execute the packet parsing for client with zero (0) timeout
715 if the protocol is active. Affected file silcd/server.c.
717 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
719 * Made the key generation options to the silcd program. Added
720 -C option, equivalent to client's option.
722 * Added new [ServerKeys] config section to the server. It
723 configures the server's public and private key.
725 * Defined generic Public Key Payload into the protocol
726 specification to send specific type of public keys and
729 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
730 public key or certificate.
732 * Implemented the GETKEY command to the server and to the
733 client library and on user interface.
735 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
737 * Made preliminary `make install' work.
739 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * Added SilcServerRekey context into silcd/idlist.h.
743 * Added the PFS support as defined in the specification to the
744 SKE protocol. Affected files lib/silcske/*.c.
746 * Added `ske_group' field to the SilcServerRekey context to hold
747 the number of the SKE group that is used with PFS in re-key.
748 Affected file silcd/idlist.h.
750 * Added PFS re-key support to the server. Affected file is
753 * Added silc_protocol_cancel to cancel execution of the next
754 state of the protocol. Affected file is
755 lib/silccore/silcprotocol.[ch].
757 * Added the re-key support with and without PFS to the client
758 library. Re-key is performed once in an hour, by default.
760 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
761 Added silc_client_rekey_callback and silc_client_rekey_final.
762 Affected files are lib/silcclient/protocol.[ch] and
763 lib/silcclient/client.[ch].
765 * Removed the `hmac_key' and `hmac_key_len' fields from the
766 SilcClientConnection structure; not needed. Affected file is
767 lib/silcclient/client.h.
771 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
773 * Do not ask whether user wants to use the negotiated private key
774 for private messages, just use it. Affected file is
775 silc/local_command.c.
777 * Added `send_enc_key' and `enc_key_len' fields to the
778 SilcIDListData structure since they are needed in the re-key
779 phase. Affected file is silcd/idlist.[ch].
781 * Implemented the simple re-key protocol into the server.
782 Affected files silcd/server.c and silcd/protocol.[ch]. The
783 re-key will be performed once in an hour, by default.
785 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
786 Added silc_server_rekey, silc_server_rekey_callback and
787 silc_server_rekey_final.
789 * Removed Tunneled flag from the protocol. Updated the code
790 and the specifications.
792 * Adde `pfs' field to the SilcIDListData to indicate whether
793 the PFS is to be performed in the re-key. Affected file is
796 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
798 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
799 int64 of at least the xintXX size. If void * is less that 4
800 bytes uint32 * will be used. Defined bool as boolean.
802 * Changed _ALL_ unsigned long and unsigned int to uint32,
803 unsgined short to uint16 in the source tree.
805 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
806 not handle clients that has entry->data.registered == FALSE.
807 They are not in the network anymore. Affected file is
810 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Implemented the sending of the SERVER_SIGNOFF notify in the
813 server. Affected file is silcd/server.c.
815 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
816 Added also silc_notify_payload_encode_args into the
817 lib/silccore/silcnotify.[ch].
819 * Implemented ther SERVER_SIGNOFF notify handling in the server.
820 Affected file silcd/packet_receive.c.
822 * Implemented the SERVER_SIGNOFF notify handling in the client
823 library. Affected file lib/silcclient/client_notify.c. Also,
824 implemnted the printing of the SERVER_SIGNOFF info to the
825 application. Affected file silc/client_ops.c.
827 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
828 if the deleting was successful. Affected file silcd/idlist.[ch].
830 * Added support for public key authentication in the connection
831 authentication protocol in the client library. Affected file
832 lib/silcclient/protocol.c.
834 * Changed the server's silc_idlist_get_clients_by_* interface
835 to support already allocated array so that new entries may be
836 added to pre-allocated array. Affected file silcd/idlist.[ch].
837 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
840 * All command reply functions in the server now calls the
841 pending command callback even if error occured. This way the
842 error will be delivered to the client as well. Affected files
843 silcd/command.c and silcd/command_reply.c.
845 * Fixed INFO command to return local server's info if no server
846 was provided. Affected file lib/silcclient/command.c.
848 * Removed RESTART command for good. Updated the code and the
851 * Rewrote parts of the task system. It is a bit simpler now.
852 Removed unsued task priorities. The affected files are
853 lib/silcutil/silctask.[ch].
855 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
857 * Moved the USERS printing from the library to the application.
858 Affected files lib/silcclient/command.c and silc/client_ops.c.
860 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
864 * Added channel key re-key support. The re-key is perfomed
865 only by the router and is done once in an hour. Added `rekey'
866 field to the SilcChannelEntry in the server. Affected files
867 silcd/server.c and silcd/idlist.h.
869 * Added silc_task_unregister_by_context into the file
870 lib/silcutil/silctask.[ch].
872 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
874 * Added SILC_UMODE_GONE mode to indicate when the client is not
875 present in the SILC network. Added also support to the local
876 command AWAY that will set this mode. Added support of showing
877 "xxx is gone" in WHOIS command. The USERS command shows the
880 * Fixed setting server and router operator privileges in the
881 server's UMODE command. Affected file silcd/command.c.
883 * Merged the SKE KE1 and KE2 payloads into one payload. The
884 new KE payload is equivalent to the old KE2 payload.
886 Cleaned up the SKE Start Payload parsing. It now uses the
887 simple buffer unformatting to do the parsing. A lot faster
890 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
891 to the SKE that is used to indicate whether both of the SKE
892 parties should perform authentication. By default only the
893 responder performs authentication. By setting this flag also
894 the initiator must do authentication. By default it is unset
895 since in normal SKE case, client to server connection, only
896 the responder should do authentication. When doing SKE between
897 two clients both should perform authentication. Updated the
898 code and the protocol specs.
900 * A little fix to IDENTIFY command in the server. Search the
901 client first by hash not nickname. Affected file is
904 * Fixed the silc_client_close_connection to support closing
905 the client to client connections wihtout deleting too much
906 data. Affected file lib/silcclient/client.c.
908 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
909 are received if protocol used to be active but is not anymore
910 the application would crash due to NULL pointer dereference.
911 Affected files silcd/server.c and lib/silcclient/client.c.
913 * Added `hash' field to the SilcClientConnection to include
914 the hash function negotiated in the SKE protocol.
916 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
917 to set the channel founder authentication data. A client can
918 claim the founder rights later by providing the authentication
919 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
920 This way the channel founder can regain the channel founder
921 privileges even it is left the channel. This works only on
922 local server and the client must be connected to the same
923 server to be able to regain the founder rights. Updated the
924 protocol specs accordingly.
926 Added support to the CMODE command in the client to set the
927 founder auth data. Read the README to see how to set it.
929 Added support to the CUMODE command to claim the founder
930 rights. Read the README to see how to do it.
932 Added support for the founder authentication to the Channel
933 Entry in the server. Affected file silcd/idlist.h.
935 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
936 server's CMODE command. Affected file silcd/command.c.
938 * Added the following new functions into lib/silccore/silcauth.[ch]:
939 silc_auth_get_method and silc_auth_get_data.
941 * The server now saves the remote hosts public key to the
942 SilcIDListData pointer. Affected file silcd/protocol.c.
944 * The normal server now does not remove the channel entry from
945 the cache if the founder authentication data is set. It used
946 to remove it if the founder was the last one on the channel on
947 the server and left the channel. The auth data is saved and
948 if the channel is re-joined later the old entry is used with
949 the old auth data. Affected files silcd/command_reply.c and
952 * Removed the `pkcs' field from the SilcIDListData structure
953 in the server; it is not used. Affected file silcd/idlist.h.
955 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
957 * Fixed packet processing on slow links. Partial packets were
958 never re-processed because the incoming data buffer was cleared
959 by the application. Application must not directly clear the
960 sock->inbuf, the packet processing routines handle it. Fixed
961 this in client library and in server.
963 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
965 * Fixed the WHOIS and IDENTIFY send reply function to really
966 check whether to send list or just one entry. Affected file
969 * Cleaned up the LEAVE command's channel key distribution. The
970 affected file silcd/command.c.
972 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
973 can enforce the channel mode as well. In that case the ID
974 includes the ID of the server. The code now enforces the
975 mode change if the router have different mode than the server.
977 * The notify client operation with CMODE_CHANGE notify can now
978 return NULL client_entry pointer if the CMODE was not changed
979 by client. Application must check for this.
981 * Added <Server ID> argument to INFO command to support server
982 info fetching by Server ID.
984 * Added silc_server_announce_get_channel_users to get assembled
985 packets of channel users of the specified channel. Affected
986 file silcd/server.[ch].
988 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
989 was freed underneath the ID Cache.
991 * Re-announce clients when the server received CHANNEL_CHANGE
992 notify from the router. Affected file silcd/packet_send.c.
994 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
996 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
997 crashed since it did not handle the fact that there is no cipher
998 called "3" and didn't check the error condition. Now fixed.
1000 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1001 flag. It can be used to send message requests.
1003 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1005 * Implemented the RESTART command in the client.
1007 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1008 notice type messages. Added notice printing to the user
1011 * The channel keys are not re-generated if the channel's mode
1012 is PRIVKEY, ie private key on the channel exists. Affected
1013 files silcd/server.c and silcd/command.c.
1015 * Fixed a little bug in channel message delivery when channel
1016 private keys are set in the server. Affected file is
1017 silcd/packet_send.c.
1019 * Changed the setting on channel->on_channel = TRUE from the
1020 silc_client_save_channel_key to the JOIN command reply. The
1021 key payload is not received if the private channel key is set.
1022 Affected file lib/silcclient/command_reply.c and the
1023 lib/silcclient/client_channel.c.
1025 * When the CMODE_CHANGE notify is sent and the channel private
1026 key mode is removed the channel key must be re-generated in
1027 other cells as well. Added this support for the router in the
1028 silcd/packet_receive.c.
1030 * Added new local command NOTICE to send notice message on
1031 channel. Affected file silc/local_command.[ch].
1033 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Added new local command ME to the client. It is used to send
1036 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1037 some action. Affected file silc/local_command.[ch].
1039 * Changed channel_message and private_message client operations
1040 to deliver the message flags to the application. Added also
1041 the `flags' arguments to the silc_client_send_channel_message
1042 and silc_client_send_private_message functions. Affected file
1045 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1047 * Redefined the Private Message Payload to support private message
1048 keys and to support the new private message flags. Updated
1049 the protocol specs. Flags makes it possible to have for example
1050 CTCP style messages.
1052 * Added new type SilcPrivateMessagePayload and defined an API
1053 for it in the lib/silcclient/silcprivate.[ch].
1055 * Tested private message private keys successfully. Tested the
1056 private message key set, unset and list commands with the new
1059 * Redefined the Channel Message Payload to include the channel
1060 message flags (equal with private message flags) to support
1061 for example CTCP style messages.
1063 * Defined some of the message (for channel and private message)
1064 flags. Updated the protocol specs and added the flags to the
1065 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1067 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1069 * Added SilcKeyAgreementStatus type to the key agreement routines
1070 to indicate the current status and error if one occured.
1071 The status types are defined in the lib/silcclient/silcapi.h.
1073 * Added new local command KEY that is used to set and unset private
1074 keys for channels, set and unset private keys for private messages
1075 with remote clients and to send key agreement requests and
1076 negotiate the key agreement protocol with remote client. The
1077 key agreement is supported only to negotiate private message keys,
1078 it currently cannot be used to negotiate private keys for channels,
1079 as it is not convenient for that purpose.
1081 * Fixed a minor pending callback setting bug in the function
1082 silc_client_get_client_by_id_resolve, now the function works.
1083 Affected file lib/silcclient/idlist.c.
1085 * Added function silc_net_get_local_port to get local bound
1086 port by socket. Added to lib/silcutil/silcnet.[ch].
1088 * Added `sockets' and `sockets_count' fields to the SilcClient
1089 object. They hold the sockets of the listenning sockets in
1090 the client. Listenning sockets may be for example the key
1091 agreement server. Affected file lib/silcclient/client.[ch].
1092 Added functions the silc_client_add_socket and the
1093 silc_client_del_socket. They are exported to the application
1096 * Added ~./silc/clientkeys to support other client's public keys.
1098 * Renamed verify_server_key client operation to verify_public_key
1099 and added one argument to indicate the type of the connection
1100 (server, client etc.).
1102 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Added silc_server_connection_auth_request to handle the
1105 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1106 silcd/packet_receive.[ch].
1108 * Added silc_server_send_connection_auth_request into the
1109 silcd/packet_send.c to send the connection auth request packet.
1111 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1114 * Fixed the public key authentication in responder side in the
1115 server. The `auth_data' pointer includes the SilcPublicKey
1116 not the path to the public key. Affected file silcd/protocol.c.
1118 * Implemented the public key authentication in the initiator side
1119 in the server. Affected file silcd/protocol.c.
1121 * Removed the [RedirectClient] config section from the server
1122 configuration. Is not needed and I don't want to implement it.
1124 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1126 * Cleaned up the CMODE command in the server. It now works
1127 correctly and supports all the modes defined in the protocol.
1128 Affected file is silcd/command.c.
1130 * Added `hmac_name' field to the SilcChannelEntry in the server
1131 to hold the default HMAC of the channel. It can be set when
1132 creating the channel (with JOIN command). Affected files
1135 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1136 type to indicate the change of the current cipher and hmac
1137 on the channel. Client can safely ignore the <cipher> argument
1138 (if it chooses to do so) since the CHANNEL_KEY packet will
1139 force the channel key change anyway. The <hmac> argument is
1140 important since the client is responsible of setting the new
1141 HMAC and the hmac key into use.
1143 * Fixed the CMODE command in the client library as well.
1145 * Tested CMODE command in router environment successfully.
1147 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1149 * Show the version of the remote client (or server) when connecting
1150 to the server. It is logged to the log file. Affected file
1151 is silcd/protocol.c.
1153 * Fixed the KILLED notify handling in the client library. The
1154 client must be removed from all channels when receiving the
1157 Also, do not remove the client entry when giving the KILL
1158 command but when the KILLED notify is received.
1160 * Removed silc_idlist_find_client_by_nickname from the server.
1161 Not needed anymore. Affected files silcd/idlist.[ch].
1163 * Implemented the CHANNEL_CHANGE notify type handling to the
1164 server. Affected file silcd/server.c.
1168 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1170 * Added silc_server_send_notify_invite to send the INVITE
1171 notify between routers.
1173 * Implemented the INVITE command correctly to the server.
1175 * Implemented the INVITE notify type handling in the server.
1177 * Implemented the INVITE command to the client library and on the
1180 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Added function silc_server_get_client_resolve to find the
1183 client entry by ID from all ID lists and then resolve it
1184 (using WHOIS) if it cannot be found. Affected file is
1187 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1189 * Implemented the BAN command to the client library.
1191 * The JOIN command in the server now checks the invite list
1194 * Changed the silc_command_reply_payload_encode_va and the
1195 silc_command_payload_encode_va to support that if argument is
1196 NULL it ignores and checks the next argument. Affected file
1197 lib/silccore/silccommand.c.
1199 * Added silc_server_send_notify_ban to send the BAN notify
1200 type between routers.
1202 * Chaned the silc_notify_payload_encode to support that if
1203 argument is NULL it ignores and checks the next argument.
1204 Affected file lib/silccore/silcnotify.c.
1206 * Tested ban lists in router environment successfully.
1208 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1210 * Implemented BAN command to the server, in silcd/command.[ch].
1212 * Removed the BAN and INVITE_LIST modes from the CMODE command
1215 * Added function silc_string_match to regex match two strings.
1216 Affected files lib/silcutil/silcutil.[ch].
1218 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Redefined parts of the SilcChannelEntry in the server to support
1221 the new ban and invite lists.
1223 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Redefined the INVITE command. The same command can be used to
1226 invite individuals to the channel but also to manage the invite
1227 list of the channel (to add to and remove from the invite list).
1228 Updated the protocol specs.
1230 * Added new command SILC_COMMAND_BAN that can be used to manage
1231 the ban list of the channel. Updated the protocol specs.
1233 * Removed the channel modes: the SILC_CMODE_BAN and the
1234 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1235 in the CMODE command. The equivalent features are now available
1236 using INVITE and BAN commands. Updated the protocol specs.
1238 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1239 in the network about change in the current ban list. The notify
1240 type is not used by the client.
1242 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1243 support the invite lists.
1245 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1247 * Added new function silc_string_regexify that converts string
1248 including wildcard characters into regex string that can
1249 be used by the GNU regex library. Added into the file
1250 lib/silcutil/silcutil.[ch].
1252 Added silc_string_regex_combine to combine to regex strings
1253 into one so that they can be used as one regex string by
1254 the GNU regex library. Added into the file
1255 lib/silcutil/silcutil.[ch].
1257 Added silc_string_regex_match to match two strings. It returns
1258 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1260 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Imported GNU regex to the soruce tree into lib/contrib.
1263 Fixed some compiler warning from the regex.c.
1265 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1267 * Fixed MOTD command in the server to work in router environment.
1269 * Fixed the MOTD command in the client library to support
1270 the server argument in the command.
1272 * Added `nickname_len' argument to the silc_idlist_add_client
1273 in the server, as the `nickname' argument may be binary data
1276 * Added silc_idlist_get_channels to return all channels from
1279 * Implemented LIST command to the server. Affected file is
1282 * Implemented the LIST command to the client library and on the
1285 * Added [<user count>] argument to the LIST command reply.
1286 With private channels the user count is not shown.
1288 * Updated TODO and README.
1290 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1292 * The client entry's data.registered must be TRUE even with
1293 global client entry on global client list. The data.registered
1294 is used to check whether the client is anymore in the network,
1295 for example with WHOWAS command so it must be valid.
1297 * Fixed the WHOWAS command in the server. It now actually works
1298 in router environment. Added function into silcd/command_reply.c
1299 silc_server_command_reply_whowas_save.
1301 * Added silc_idlist_purge function to the silcd/idlist.c
1302 to periodically purge the ID Cache.
1304 * Fixed INFO command in the server. It works now in router
1305 environment. Added <server name> argument to the INFO command
1306 reply. Updated the protocol specs.
1308 * Fixed minor bug in silc_idcache_purge to not purge if the
1309 expire value is zero.
1311 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1312 they were buggy because of the WHOWAS information.
1314 * Fixed local command MSG to handle the async resolving of
1315 the remote client properly. It used to fail the first MSG.
1316 Affected file silc/local_command.c.
1318 * Added `data_len' field to SilcIDCache context.
1320 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1322 * Update TODO. Todo in commands in the server.
1324 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1326 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1327 used by routers as broadcast packet to inform other routers
1328 about the changed user mode.
1330 Implemented the notify handling in the server. Affected file is
1331 silcd/packet_receive.c. Added the function
1332 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1334 * Added new generic Channel Payload and deprecated the New Channel
1335 Payload. The New Channel Payload is now the generic Channel
1338 * Added new argument `mode' to the silc_server_send_new_channel
1339 as it is required in the Channel Payload now.
1341 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1342 and created a new and real SilChannelPayload to represent the
1343 new generic Channel Payload. Implemented the encode/decode
1344 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1346 * Added silc_server_get_client_channel_list to return the list
1347 of channels the client has joined for WHOIS command reply.
1348 Affected file silcd/server.[ch].
1350 * Implemented the channel list sending in the WHOIS command reply
1351 in server and in the client.
1353 Implemented the channel list displaying on the user interface
1354 as well. Affected file silc/client_ops.c.
1356 * Added silc_channel_payload_parse_list to parse list of Channel
1357 Payloads. It returns SilcDList list of SilcChannelPayloads.
1358 Client for example can use this function to parse the list of
1359 channels it receives in the WHOIS command reply. The caller
1360 must free the list by calling silc_channel_payload_list_free.
1361 Affected files lib/silccore/silcchannel.[ch].
1363 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1365 * Added one new argument <user mode> to the WHOIS command reply
1366 to return the mode of the user in SILC. Updated the protocol
1369 Implemented it to the server and client.
1371 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1373 * Fixed the mode printing on the user interface on joining.
1374 Affected file silc/client_ops.c.
1376 * Implemented the UMODE command and user modes in general to the
1377 client library and to the user interface.
1379 * Implemented the UMODE command to the server.
1381 * The server now sends UNKNOWN_COMMAND error status if client sends
1382 unknown command. Affected file silcd/command.c.
1384 * All server commands now handle the command identifier the right
1385 way when sending the command reply to the client. The client can
1386 use to identify the command replies with the identifier.
1388 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * Added silc_server_get_client_route to resolve the route to
1391 the client indicated by the client ID. Affected file is
1394 * Added silc_server_relay_packet as general function to relay
1395 packet to arbitrary destination. This deprecates functions
1396 like _send_private_message_key, _relay_notify etc. Affected
1397 file is silcd/packet_send.[ch].
1399 Removed silc_server_send_key_agreement,
1400 silc_server_send_private_message_key and
1401 silc_server_packet_relay_notify functions from the file
1402 silcd/packet_send.[ch].
1406 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1407 server. Affected file silcd/packet_receive.[ch].
1409 * Implemented the KILL command to the client. Implemented the
1410 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1411 Affected files lib/silcclient/command[_reply].c and
1412 lib/silcclient/client_notify.c. Implemented the KILL notify
1413 printing in the user inteface.
1415 * Fixed a lot silc_parse_nick memory leaks from the client
1416 library in the file lib/silcclient/command.c.
1418 * Changed the silc_server_send_notify_on_channels's `sender'
1419 argument from SilcSocketConnection to SilcClientEntry to
1420 check the sender as entry and not as connection object and not
1421 to send to the client provided as argument. The affected file
1422 is silcd/packet_send.[ch].
1424 * The notify packets that are destined directly to the client used
1425 to not to be processed by the server. Now changed that and the
1426 server processes all notify packets. After relaying the packet
1427 to the client the notify packet is processed in the server.
1429 * The silc_server_free_client_data now checks whether there is
1430 pending outgoing traffic for the client and purges the data to
1431 the network before removing the client entry.
1433 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1435 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1436 an client is killed from the SILC Network. Updated the protocol
1439 Added new function silc_server_send_notify_killed to the
1440 silcd/packet_send.[ch].
1442 * Added function silc_server_packet_relay_notify to relay notify
1443 packets that are destined directly to a client. In this case
1444 the server does not process the notify packets but merely relays
1445 it to the client. Affected file silcd/packet_send.[ch].
1447 Added also silc_server_packet_process_relay_notify to check
1448 whereto relay the notify. Affected file is
1449 silcd/packet_receive.[ch].
1451 * Implemented the KILL command to the server.
1455 * Added the backup schema desgined last fall to the protocol
1456 specs for everyone to see. The specification is in the
1457 *-spec-xx.txt draft and the packet type definitions for the
1458 backup routers is in *-pp-xx.txt draft. Thusly, added also
1459 new packet type SILC_PACKET_CELL_ROUTERS.
1461 * A big security problem in the implementation discovered. The
1462 signoff of an client did not cause new channel key generation
1463 which it of course should've done. The channel keys must be
1464 always re-generated when client leaves (or signoffs) the channel.
1465 The silc_server_remove_from_channels funtion now handles
1466 the channel key re-generation.
1468 * Added `sender' argument to the silc_server_send_notify_on_channels
1469 to not to send the client provided as argument. Affected file
1470 silcd/packet_send.[ch].
1472 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1474 * Implemented OPER and SILCOPER commands into the server and
1477 * Added silc_auth_verify and silc_auth_verify_data to verify
1478 the authentication directly from the authentication payload.
1479 It supports verifying both passphrase and public key based
1480 authentication. Affected file lib/silccore/silcauth.[ch].
1482 * Added `hash' field to the SilcIDListData structure. It is the
1483 hash negotiated in the SKE protocol. Affected file is
1486 * Slight redesigning of the SilcAuthPayload handling routines.
1487 Do not send SilcPKCS but SilcPublicKey as argument.
1489 * Implemented the public key authentication support to the
1490 serverconfig. The public key is loaded from the provided path
1491 and saved as authentication data to void * pointer. Thus,
1492 changed the unsigned char *auth_data to void *auth_data;
1494 * Fixed SHUTDOWN command to send the reply before the server
1495 is shutdown. :) Affected file silcd/command.c.
1497 * Fixed fatal bug in CONNECT command. The hostname was invalid
1498 memory and server crashed. Affected file silcd/command.c.
1500 * Fixed fatal bug in CLOSE command. The server_entry became
1501 invalid but was referenced later in the command. Affected file
1504 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1506 * Fixed fatal bug in failure packet handling. Server ignored
1507 the failure and thus crashed when it came.
1511 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1513 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1514 that the command may be executed only once in (about) 2 seconds.
1515 The old SILC_CF_LAG flag is same but allows command bursts up
1516 to five before limiting.
1518 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1519 server code. Various commands now includes the CF_LAG_STRICT
1520 flag to disallow any kind of miss-use of the command.
1522 * Fixed the silc_buffer_unformat to not to allocate any data
1523 if the length of the data is zero. It used to allocate the
1524 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1526 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * Changed the format of AdminConnection configuration section
1529 in the server. Added username of the admin to the format.
1530 Affected files silcd/serverconfig.[ch].
1532 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1533 to return admin configuration data by host, username and/or
1536 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1538 * Implemented WHOWAS command to the server. Added the functions:
1540 silc_server_command_whowas_parse,
1541 silc_server_command_whowas_send_reply,
1542 silc_server_command_whowas_from_client and
1543 silc_server_command_whowas_from_server
1545 * Added <Client ID> argument to the WHOWAS command reply. Updated
1546 the protocol specs accordingly.
1548 * Implemented WHOWAS command and command_reply to the client
1551 Implemented the WHOWAS printing on the user interface.
1553 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1555 * Added new argument to the WHOWAS command reply, the real name.
1556 It is an optional argument. Updated the protocol specs.
1558 * Added SilcIDCacheDestructor callback that is registered when
1559 the SilcIDCache is allocated. The callback is called when
1560 an cache entry in the ID Cache expires, or is purged from the
1561 cache. Added into lib/silccore/idcache.[ch].
1563 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1564 to destruct the client entries when the cache entry expires.
1565 Other ID Cache's in server and in the client library ignores
1568 * If the ID Cache entry's `expire' field is zero then the entry
1569 never expires. Added boolean `expire' argument to the
1570 silc_idcache_add function in the lib/silccore/idcache.[ch].
1571 If it is TRUE the default expiry value is used.
1573 * Added silc_server_free_client_data_timeout that is registered
1574 when client disconnects. By default for 5 minutes we preserve
1575 the client entry for history - for WHOWAS command.
1577 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1579 * Added support to the server to enforce that commands are not
1580 executed more than once in 2 seconds. If server receives
1581 commands from client more frequently, timeout is registered
1582 to process the commands. Affected file silcd/command.c.
1583 Added new function silc_server_command_process_timeout.
1585 * Changed NICK_NOTIFY handling in client library to check that
1586 if the client's nickname was changed, so there is no need to
1587 resolve anything from the server.
1589 * Removed error printing from the WHOIS and IDENTIFY commands.
1590 If error occurs then it is ignored silently in the client library.
1591 The application, however, may map the received error to
1592 human readable error string. The application currently maps
1593 the NO_SUCH_NICKNAME error to string.
1595 * Made the command status message public to the application. Moved
1596 them from lib/silcclient/command_reply.c to
1597 lib/silcclient/command_reply.h. The application can map the
1598 received command status to the string with the
1599 silc_client_command_status_message function.
1601 * Added check to the server to check that client's ID is same
1602 as the Source ID in the packet the client sent. They must
1605 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1607 * Added dist-bzip hook to the Makefile.am to make bzip2
1608 compressed distributions.
1610 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1612 * Server now enforces the maximum length for the nickname and
1613 the channel as protocol specification dictates. 128 bytes for
1614 nickname and 256 bytes for channel name.
1616 * Moved the WHOIS printing to the application. The client libary
1617 does not print out the WHOIS information anymore, the application
1618 must do it. Renamed silc_client_command_reply_whois_print to
1619 the silc_client_command_reply_whois_save.
1621 The client's idle time is also sent to the application now, and
1622 the idle is shown on screen.
1624 * Added silc_client_command_reply_identify_save to save the
1625 received IDENTIFY entries.
1627 * Do not check for channel private keys in message sending and
1628 reception if the channel does not have the PRIVKEY mode set.
1629 Affected file lib/silclient/client_channel.c.
1631 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1633 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1634 just surfaced after chaning the JOIN procedure.
1636 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1638 * Added silc_client_get_clients_by_list to get client entries
1639 from Client ID list, that is returned for example by JOIN
1640 and USERS command replies. The application should use this
1641 function for example when JOIN command reply is received to
1642 resolve the clients already on the channel (library does not
1643 do that anymore as USERS command reply is not used in the JOIN
1644 procedure anymore). Affected files lib/silcclient/silcapi.h and
1645 lib/silcclient/idlist.c.
1647 * JOIN command reply and USERS command reply returns now SilcBuffer
1648 pointers instead of unsigned char pointers when returning
1649 the client list and mode list.
1651 * Added <Client ID> argument to the JOIN command reply, mainly
1652 for the server to identify for which client the command was
1653 originally sent. Updated protocol specs accordingly.
1655 * Added SilcDlist private_key pointer to the SilcChannelEntry
1656 in the client to support the channel private keys. Affected
1657 file is lib/silcclient/idlist.h.
1659 * Added SilcChannelPrivateKey argument to the function
1660 silc_client_send_channel_message so that application can choose
1661 to use specific private ke if it wants to. If it is not provided,
1662 the normal channel key is used, unless private keys are set.
1663 In this case the first (key that was added first) is used
1664 as the encryption key.
1666 * Implemented the support for channel private key handling.
1667 Implemented the following functions:
1669 silc_client_add_channel_private_key,
1670 silc_client_del_channel_private_keys,
1671 silc_client_del_channel_private_key,
1672 silc_client_list_channel_private_keys and
1673 silc_client_free_channel_private_keys
1675 Affected file lib/silcclient/client_channel.c.
1677 * Added the support for the private keys in the channel message
1678 sending and encryption and in the message reception and
1679 decryption. Affected funtions are
1680 silc_client_send_channel_message and silc_client_channel_message.
1682 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1684 * Added SKE's key verify callback to the client library's
1685 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1687 * Removed the statement that server (or router) must send USERS
1688 command reply when joining to the channel so that the client
1689 knows who are on the channel. Instead, the client list and
1690 client's mode list is now sent in the JOIN command reply to the
1691 client who joined channel. This is better solution.
1693 * Added function silc_server_get_users_on_channel and function
1694 silc_server_save_users_on_channel to the silcd/server.[ch].
1696 * Removed function silc_server_command_send_users from the
1699 * Do not show topic on the client library anymore. The topic is
1700 sent in the command reply notify to the application and the
1701 application must show the topic now.
1703 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1705 * Added client searching by nickname hash into the IDENTIFY and
1706 WHOIS commands in the server as they were clearly missing from
1707 them. Affected file is silcd/command.c.
1709 * Fixed a bug in private message receiving in the client library.
1710 The remote ID was freed and it wasn't supposed, now it is
1713 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Minor fix to the channel payload; allocate the data area, as it
1716 needs to be of specific length.
1718 * If the key agreement port is zero then the operating
1719 system will define the bound port. Affected files are
1720 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1722 * Added new function silc_channel_payload_decrypt into the file
1723 lib/silccore/silcchannel.[ch].
1725 * Moved the channel message etc, check from silc_packet_decrypt
1726 to applications. The library calls now a generic
1727 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1728 when the packet is either normal or special. This was done to
1729 allow more wide range of checking that was not allowed when
1730 the code was in library. Now applications can do virtually any
1731 checks to the packet and return to the library the decision how
1732 the packet should be processed. Affected files are
1733 lib/silccore/silcpacket.[ch].
1735 Added silc_server_packet_decrypt_check to the server and
1736 silc_client_packet_decrypt_check to the client library.
1738 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1739 to send with specified source and destination information.
1741 * Channel message delivery between routers was broken after the
1742 channel key distribution was fixed earlier. The channel key
1743 was used be to distributed to other routers as well which is not
1744 allowed by the protocol. Now this is fixed and channel keys
1745 really are cell specific and the channel message delivery between
1746 routers comply with the protocol specification.
1748 * Fixed various commands in server to check also the global list
1749 for the channel entry and not just the local list. The affected
1750 file silcd/command.c.
1752 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1754 * Added assert()s to buffer formatting and unformatting routines
1755 to assert (if --enable-debug) when error occurs. Affected
1756 file: lib/silcutil/silcbuffmt.c.
1758 * Changed to auto-reconnect to check whether the remote host is
1759 router and register the re-connect timeout if it is. It used
1760 to check that whether we are normal server, but router must do
1761 auto-reconnect with another router as well. Affected file
1764 * Removed the [<key len>] option from CMODE command as the cipher
1765 name decides the key length, nowadays. See the defined ciphers
1766 from the protocol specification.
1768 * Added [<hmac>] option to the CMODE command to define the HMAC
1769 for the channel. Added SILC_CMODE_HMAC channel mode.
1771 * Added [<hmac>] option for the JOIN command so that user can
1772 select which HMAC is used to compute the MACs of the channel
1775 * Added Hmac field to the Channel Message Payload. The integrity
1776 of plaintext channel messages are now protected by computing
1777 MAC of the message and attaching the MAC to the payload. The
1778 MAC is encrypted. Now, it is clear that this causes some
1779 overhead to the size of the packet but rationale for this is that
1780 now the receiver can verify whether the channel message decrypted
1781 correctly and also when private keys are set for the channel the
1782 receiver can decrypt the packet with several keys and check from
1783 the MAC which key decrypted the message correctly.
1785 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1786 lib/silccrypt/silccipher.[ch].
1788 * Added silc_hash_len to return the digest length into the
1789 lib/silcrypt/silchash.[ch].
1791 * Rewrote parts of Silc Channel Payload interface in the
1792 lib/silccore/silcchannel.[ch]. The encode function now also
1793 encrypts the packet and parse function decrypts it.
1795 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1797 * Fixed a minor formatting bug in the SKE's key material processing.
1798 It actually might have processed the keys wrong way resulting
1801 * Redefined the mandatory HMAC algorithms and added new algorithms.
1802 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1803 and hmac-md5 truncated to 96 bits. The mandatory is now
1804 hmac-sha1-96. Rest are optional (including the one that used
1805 to be mandatory). Rationale for this is that the truncated HMAC
1806 length is sufficient from security point of view and can actually
1807 make the attack against the HMAC harder. Also, the truncated
1808 HMAC causes less overhead to the packets. See the RFC2104 for
1811 * Added new [hmac] configuration section. The SKE used to use
1812 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1813 is of course wrong. The official names that must be proposed in
1814 the SKE are the ones defined in the protocol specification
1815 (hmac-sha1-96 for example). The user can configure any hmac
1816 using any hash function configured in the [hash] section. At
1817 least, the mandatory must be configured.
1819 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1821 * Added HMAC list to the SKE proposal list. It has now both
1822 hash algorithm list and HMAC list. This makes the protocol
1823 incompatible with previous versions. The SKE now seems to work
1824 the way it is supposed to work, for the first time actually.
1826 * Defined plain Hash algorithms to the protocol specification.
1829 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1831 * Implemented support for key agreement packets into the server.
1832 Added functions silc_server_key_agreement and
1833 silc_server_send_key_agreement. Other than these functions,
1834 server has nothing to do with this packet.
1836 * Added support for private message key packets into the server.
1837 Added functions silc_server_private_message_key and
1838 silc_server_send_private_message_key.
1842 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1843 called in the protocol's final callback instead in the END
1844 protocol state. This makes a little more sense and in the same
1845 time in client we can use the same protocol routines for normal
1846 key exchange and to key agreement packet handling as well.
1848 * Added to both client's and server's KE protocol context the
1849 SilcSKEKeyMaterial pointer to save the key material. We will
1850 bring the key material to the protocol's final callback by doing
1851 this. The final callback must free the key material.
1853 * Added SKE's packet_send callback into client's KE protocol
1854 context so that the caller can choose what packet sending function
1855 is used. This way we can use different packet sending when
1856 doing normal SKE when doing key agreement packet handling (in
1857 the key agreement packet handling we do not want to encrypt
1860 * Implemented the responder side of the key agreement routines
1861 in the client. The client can now bind to specified port and
1862 accept incoming key negotiation. The key material is passed
1863 to the application after the protocol is over.
1865 * Implemented the processing of incoming Key Agreement packet
1866 in the client. Added function silc_client_key_agreement to
1869 * Implemented the intiator side of the key agreement routines
1870 in the client. The client can now initiate key agreement with
1871 another remote client. The key material is passed to the
1872 application after the protocol is over.
1874 * Created client_keyagr.c to include all the key agreement
1877 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1878 SILC_TASK_CALLBACK except that it is not static.
1880 * Created client_notify.c and moved the Notify packet handling
1881 from the client.[ch] into that file.
1883 * Created client_prvmsg.c and moved all private message and
1884 private message key routines from the client.[ch] into that file.
1886 * Create client_channel.c and moved all channel message and
1887 channel private key routines from the client.[ch] into that file.
1889 * Changed silc_client_get_client_by_id_resolve to resolve with
1890 WHOIS command instead of IDENTIFY command, in the file
1891 lib/silclient/idlist.c.
1893 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1895 * Implemented the SKE's responder side to the Client library.
1897 * When FAILURE is received to the protocol do not trust it
1898 blindly. Register a timeout to wait whether the remote closes
1899 the connection as it should do it, only after that process the
1900 actual failure. This was changed to both client and server.
1902 * Added client_internal.h to include some of the structures
1903 there instead of client.h in lib/silcclient/.
1905 * Added function silc_task_unregister_by_callback to unregister
1906 timeouts by the callback function.
1908 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1910 * Some "Incomplete WHOIS info" errors has been appearing on the
1911 log files. Took away the entry->userinfo check from WHOIS
1912 reply sending. The entry->userinfo is now " " if client did not
1913 provide one. I thought this was fixed earlier but something
1914 is wrong still. Let's see if the error still appears.
1916 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1918 * Fixed a minor bug in the login when the channel key is
1919 re-generated in the server. It used to generate the key in
1920 wrong order and thus caused problems in the channel traffic.
1922 * Fixed a minor bug in channel key distsribution after
1923 KICK command. The key was not sent to the router even though
1926 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1928 * Added silc_ske_process_key_material_data as generic routine
1929 to process any key material as the SILC protocol dictates. The
1930 function is used by the actual SKE library but can be used by
1931 applications as well. This relates to the private message keys
1932 and the channel private keys since they must be processed the
1933 same way the normal SILC session keys. The protocol dictates
1934 this. Affected files: lib/silcske/silcske.[ch].
1936 Added also silc_ske_free_key_material to free the
1937 SilcSKEKeyMaterial structure.
1939 * Defined silc_cipher_set_key function to set the key for
1940 cipher without using the object's method function. The affected
1941 files: lib/silccrypt/silccipher.[ch].
1943 * Implemented silc silc_client_add_private_message_key,
1944 silc_client_add_private_message_key_ske,
1945 silc_client_del_private_message_key,
1946 silc_client_list_private_message_keys and
1947 silc_client_free_private_message_keys functions in the
1950 Added functions silc_client_send_private_message_key to send
1951 the Private Message Key payload and silc_client_private_message_key
1952 to handle incoming Private Message Key payload.
1954 * Added Cipher field to the Private Message Key payload to set
1955 the cipher to be used. If ignored, the default cipher defined
1956 in the SILC protocol (aes-256-cbc) is used.
1958 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Removed lib/silcclient/ops.h file.
1962 Redefined parts of the SILC Client Library API. Created new
1963 file silcapi.h that deprecates the ops.h file and defines the
1964 published Client Library API. Defined also private message key
1965 API and channel private key API into the file.
1967 This is the file that the application must include from the
1968 SILC Client Library. Other files need not be included by
1969 the application anymore.
1971 * Added new key_agreement client operation callback and also
1972 defined the Key Agreement library API for the application.
1974 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1976 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1977 is used by clients to request key negotiation between another
1978 client in the SILC network. If the negotiation is started it
1979 is performed using the SKE protocol. The result of the
1980 negotiation, the secret key material, can be used for example
1981 as private message key.
1983 Implemented the Key Agreement payload into the files
1984 lib/silccore/silauth.[ch].
1986 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * Redefined ciphers for the SILC protocol. Added some new ciphers
1989 and defined the key lengths for the algorithms. Changed the
1990 code accordingly. The default key length is now 256 bits.
1992 * Fixed SKE key distribution function silc_ske_process_key_material
1993 when the key length is more than 128 bits. The default key
1994 length in SILC is now 256 bits.
1996 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1997 to indicate unsupported algorithm.
1999 * Renamed rijndael.c to aes.c and all functions as well.
2001 * Fixed a long standing channel key setting bug in client library.
2002 Weird that it has never surfaced before.
2004 * Fixed bug in channel deletion. If the entire channel is removed
2005 then it must also delete the references of the channel entry
2006 from the client's channel list as the client's channel entry and
2007 the channel's client entry share same memory.
2009 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2011 * Implemented CONNECT and SHUTDOWN commands in the client.
2013 * Implemented CLOSE command to the client.
2015 * Added the function silc_idlist_find_server_by_name into the
2016 files silcd/idlist.[ch].
2018 Added the function silc_idlist_find_server_by_conn into the
2019 files silcd/idlist.[ch].
2021 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2023 * DIE command was renamed to SHUTDOWN. Updated the both code
2026 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2027 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2029 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2032 * Added function silc_server_create_connection function to create
2033 connection to remote router. My server implementation actually
2034 does not allow router to connect to normal server (it expects
2035 that normal server always initiates the connection to the router)
2036 so the CONNECT command is only good for connecting to another
2039 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2042 or some other client was kicked from the channel.
2044 Implemented the handling of the notify type to both client
2047 Implemented silc_server_send_notify_kicked to send the KICKED
2048 notify. It is used to send it to the server's primary router.
2050 * Implemented the KICK command into server and client.
2052 * Added `query' argument to the silc_idlist_get_client function
2053 to indicate whether to query the client from server or not if
2056 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2057 to indicate that the client is not channel founder.
2061 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * Removed the rng context from SilcPacketContext structure and
2064 changed that the packet routine uses the Global RNG API.
2066 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2068 * Added support for quit message that client can "leave" on the
2069 channel when it quits the SILC. It is ditributed inside the
2070 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2072 Added silc_server_free_client_data that will take the
2073 signoff message as argument.
2075 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2077 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Updated parts of the protocol specification to keep it up
2082 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2084 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2085 payloads in one packet.
2087 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2088 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2089 use now the new List flag.
2091 * Also deprecated the following packet types: REPLACE_ID,
2092 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2094 * Added list support for Notify packet in server.
2096 * Added silc_server_send_notify_channel_change to send the
2097 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2098 the silc_server_send_replace_id.
2100 * Added silc_server_send_notify_nick_change to send the
2101 NICK_CHANGE notify type. Deprecates the function
2102 silc_server_send_replace_id.
2104 * Added silc_server_send_notify_join to send the JOIN notify type.
2105 Deprecates the function silc_server_send_new_channel_user.
2107 * Added silc_server_send_notify_leave to send LEAVE notify type.
2108 Deprecates the function silc_server_send_remove_channel_user.
2110 * Added silc_server_send_notify_cmode and
2111 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2112 types. Deprecates the silc_server_send_set_mode function.
2114 * Added SERVER_SIGNOFF notify type to indicate that server has
2115 quit. This means that all clients on the channel from that
2116 server will drop. This can be also used when netsplit happens.
2118 Deprecated REMOVE_ID packet type since it is not needed anymore
2121 Added silc_server_send_notify_server_signoff to send the
2122 SERVER_SIGNOFF notify type. Deprecates the function
2123 silc_server_send_remove_id.
2125 Added also silc_server_send_notify_signoff to send the
2126 SIGNOFF notify type.
2128 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2129 SILC protocol from this day on. Changed the protocol
2130 specification as well.
2132 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2133 notify type. It is used between routers to notify about
2134 topic changes on a channel.
2136 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2139 * Partly updated the protocol specification to comply with the
2140 changes now made. It is still though a bit outdated.
2142 * The JOIN notify type now takes one extra argument <Channel ID>.
2143 The packet used to be destined to the channel but now the
2144 JOIN type may be sent as list thus it is impossible to
2145 destine it to any specific channel. By adding this argument
2146 it is again possible.
2148 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2150 * Added CREDITS file. The CHANGES and CREDITS file will appear
2151 in the distribution as well.
2153 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2155 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2156 types in the server's silcd/packet_receive.c.
2158 * Implemented CMODE and CUMODE to work in router environment.
2160 * Fixed minor encoding and decoding buglet from the
2161 lib/silccore/silcmode.c.
2163 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2166 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2168 * Changed all SilcConfigServer* and silc_config_server* to
2169 SilcServerConfig* and silc_server_config*, respectively.
2172 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2174 * Associated the ID (client or server ID) to the Authentication
2175 Payload to avoid any possibility of forging. Updated the
2176 protocol specification and the code accordingly.
2178 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2180 * The RSA key length is now save to the RsaKey context in the
2181 key generation process in lib/silccrypt/rsa.c. The key length
2182 is now used to figure out the maximum size of the block allowed
2183 to be encrypted/signed.
2185 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2186 is equivalent to the silc_mp_mp2bin but does not allocate any
2189 * Changed silc_mp_mp2bin API to take length argument. If it is
2190 non-zero then the buffer is allocated that large. If zero, then
2191 the size is approximated using silc_mp_sizeinbase, which however
2194 * Created Global RNG API which is global RNG that application can
2195 initialize. After initializing, any routine anywhere in the
2196 code (including library) can use RNG without allocating a new
2197 RNG object. This was done to allow this sort of use of the
2198 RNG in code that has no chance to allocate RNG object. All
2199 applications currently allocate this and many routines in the
2200 library use this. Affected file lib/silccrypt/silcrng.[ch].
2202 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2203 it to use the Global RNG API.
2205 * Defined Authentication Payload into protocol specification that
2206 is used during SILC session to authenticate entities. It is
2207 used for example by client to authenticate itself to the server
2208 to obtain server operator privileges.
2210 Implemented this payload into the lib/silccore/silcauth.[ch].
2211 Implemented also routines for public key based authentication
2212 as the new protocol specification dictates.
2214 Moved definitions of different authentication methods from
2215 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2217 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2218 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2219 silc_pkcs_verify_with_hash functions into the file
2220 lib/silccrypt/silcpkcs.[ch].
2222 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2224 * The client entry's userinfo pointer must be always valid.
2225 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2226 will fail since it requires the userinfo. Now, the userinfo
2227 is allocated as "" if actual userinfo does not exist. Actually,
2228 it must exist and it is totally Ok to drop client connections
2229 that does not announce the userinfo. However, we will make
2230 this workaround for now.
2232 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2233 to return the remote port by socket.
2235 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2237 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2238 SILC_SERVER_PENDING_EXEC and added an new macro
2239 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2240 data or when error occurs while processing the pending command.
2242 Added new argument `destructor' into silc_server_command_pending
2243 and to the SilcServerCommandPending object. This destructor is
2244 now called after calling the pending callback or if error occurs
2245 immediately. If error occurs the actual pending callback won't
2246 be called at all - only the destructor. The destructor may be
2247 NULL if destructor is not needed.
2249 All this applies for client library code as well. Similar
2250 changes were made there as well for the pending commands.
2252 In the client, the application must now allocate the
2253 SilcClientCommandContext with the silc_client_command_alloc
2256 * Added reference counter to the SilcServerCommandContext. Added
2257 function silc_server_command_alloc and silc_server_command_dup
2260 Same type of functions added to the client library for the same
2263 * Removed the cmd_ident from IDListData away since it is now
2264 global for all connections. It is the command identifier used
2265 in command sending and with pending commands. The affected file
2268 * Added reference counter to the SilcSocketConnection objecet to
2269 indicate the usage count of the object. The object won't be
2270 freed untill the reference counter hits zero. Currently only
2271 server uses this, and client ignores it. The client must be
2272 set to use this too later. The affected files are
2273 lib/silccore/silcsockconn.[ch]. Added also the function
2274 silc_socket_dup to increase the reference counter.
2276 This was mainly added because it is possible that the socket
2277 is removed underneath of pending command or other async
2278 operation. Now it won't be free'd and proper DISCONNECTING
2279 flags, etc. can be set to avoid sending data to connection that
2280 is not valid anymore.
2282 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2283 the connection. After that it sets SILC_SET_DISCONNECTED.
2284 It is, however, possible that the socket data is not still freed.
2285 The silc_server_packet_process now checks that data is not
2286 read or written to connection that is DISCONNECTED. The socket
2287 get's freed when the reference counter hits zero.
2289 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2291 * Changed the client operation API: channel_message operation's
2292 `sender' is now the client entry of the sender, not the nickname
2293 and the `channel' is the channel entry, not the channel name.
2295 In the private_message operation the `sender' is now also the
2296 client entry of the sender not the nickname.
2298 Affected file is lib/silcclient/ops.h and all applications
2299 using the client operations.
2301 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2303 * Moved the calling of ops->connect() from connect_to_server_final
2304 into receive_new_id functin since that is the point when the
2305 client is actually allowed to send traffic to network. The
2306 affected file is lib/silcclient/client.c.
2308 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2310 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2311 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2312 (if needs broadcasting) instead of broadcasting the packets one
2313 by one which would make a burst in the network traffic.
2315 * Added `broadcast' argument to the functions in silcd/server.[ch]
2316 silc_server_create_new_channel[_with_id] to indicate whether
2317 to send New Channel packet to primary router.
2319 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2321 * Added new function into the silcd/server.[ch] files:
2322 silc_server_create_new_channel_with_id to create new channel with
2323 already existing Channel ID.
2325 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2326 lib/silccore/silcpacket.h. This packet is used t send list of
2327 Set Mode payloads inside one packet. Server uses this to set
2328 the modes for the channels and clients on those channels, that it
2329 announced to the router when it connected to it. The protocol
2330 specification has been updated accordingly.
2332 * The silc_server_new_channel did not handle the packet coming
2333 from normal server as it normally does not send that. However,
2334 when it announces its channels it does send it. Implemented
2335 the support for that.
2337 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2338 into the file lib/silccore/id.h.
2340 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2342 * Fixed memory leaks in the functions silc_idlist_del_client,
2343 silc_idlist_del_channel and silc_idlist_del_server in the file
2344 silcd/idlist.c. All of those leaked like a sieve.
2346 * Fixed some small memory leaks in the client's function
2347 silc_client_notify_by_server.
2349 * Added functions into silcd/server.c: silc_server_announce_clients,
2350 silc_server_announce_channels and silc_server_announce_server.
2351 These functions are used by normal and router server to announce
2352 to its primary router about clients, channels and servers (when
2353 router) that we own. This is done after we've connected to the
2356 These functions effectively implements the following packet types:
2357 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2358 and SILC_PACKET_NEW_ID_LIST.
2360 * Added new functions into the silcd/packet_receive.[ch]:
2361 silc_server_new_id_list, silc_server_new_channel_list and
2362 silc_server_new_channel_user_list to handle the incoming
2363 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2365 * Added support of changing Channel ID in the function
2366 silc_server_replace_id. If the server that announces a channel
2367 to the router already exists in the router (with same name but
2368 with different Channel ID), router is responsible to send
2369 Replace ID packet to the server and force the server to change
2370 the Channel ID to the one router has.
2372 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2373 client that the Channel ID has been changed by the router. The
2374 normal server sends this to the client. Client must start using
2375 the new Channel ID as the channel's ID.
2377 Implemented handling of this new type into lib/silcclient/client.c
2378 into the function silc_client_notify_by_server.
2380 * Added new function silc_idlist_replace_channel_id into the files
2381 silcd/idlist.[ch] to replace the Channel ID.
2383 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2385 * Call silc_server_command_identify_check always when processing
2386 the IDENTIFY command in silcd/command.c
2388 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2390 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2391 send keepalive packets. The packet can be sent by clients,
2392 servers and routers.
2394 Added function silc_socket_set_heartbeat into the file
2395 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2396 If not set, the heartbeat is not performed. The actual
2397 heartbeat is implemented in the low level socket connection
2398 library. However, application is responsible of actually
2401 Added silc_server_send_heartbeat to send the actual heartbeat
2402 packet into silcd/packet_send.[ch]. Server now performs
2403 keepalive with all connections.
2405 * Added silc_task_get_first function into lib/silcutil/silctask.c
2406 to return the timeout task with shortest timeout. There was a bug
2407 in task unregistration that caused problems. TODO has been
2408 updated to include that task system must be rewritten.
2410 * The client library will now resolve the client information when
2411 receiving JOIN notify from server for client that we know but
2412 have incomplete information.
2414 * Rewrote parts of silc_server_remove_from_channels and
2415 silc_server_remove_from_one_channel as they did not remove the
2416 channel in some circumstances even though they should've.
2418 * Encryption problem encountered in server:
2420 The LEAVE command used to send the Channel Key packet to the
2421 router immediately after generating it. However, the code
2422 had earlier sent Remove Channel user packet but not immediately,
2423 ie. it was put to queue. The order of packets in the router
2424 was that Channel Key packet was first and Remove Channel User
2425 packet was second, even though they were encrypted in the
2426 reverse order. For this reason, MAC check failed. Now, this
2427 is fixed by not sending the Channel Key packet immediately but
2428 putting it to queue. However, this is more fundamental problem:
2429 packets that are in queue should actually not be encrypted
2430 because packets that are sent immediately gets encrypted
2431 actually with wrong IV (and thus MAC check fails). So, packets
2432 that are in queue should be encrypted when they are sent to
2433 the wire and not when they put to the queue.
2435 However, the problem is that the current system has not been
2436 designed to work that way. Instead, the packet is encrypted
2437 as soon as possible and left to the queue. The queue is then
2438 just purged into wire. There won't be any fixes for this
2439 any time soon. So, the current semantic for packet sending
2442 o If you send packet to remote host and do not force the send
2443 (the packet will be in queue) then all subsequent packets to the
2444 same remote host must also be put to the queue. Only after the
2445 queue has been purged is it safe again to force the packet
2448 o If you send all packets immediately then it safe to send
2449 any of subsequent packets through the queue, however, after
2450 the first packet is put to queue then any subsequent packets
2451 must also be put to the queue.
2453 Follow these rules and everything works fine.
2455 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2457 * Added new function silc_server_remove_clients_by_server to
2458 remove all client entries from ID list when the server connection
2459 is lost. In this case it is also important to invalidate all
2460 client entires as they hold the invalid server entry. This
2461 fixes fatal bug when server has lost connection and will reconnect
2464 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Made some sanity checks to silc_server_daemonise like to check
2467 whether the requested user and group actually exists.
2469 * Added sanity check to SKE's silc_ske_responder_finish to check
2470 that the public and private key actually is valid.
2472 * Invalidate the client's nickname when receiving Replace ID
2473 packet and the Client ID is being replaced. This means that the
2474 server will query the nickname if someone needs it (client)
2477 * Sort the ID Cache in client library when the ID Cache data
2478 has changed (needs sorting).
2480 * Do not allow for SILC client to create several connections to
2481 several servers. The client does not support windows right now
2482 and generating multiple connections causes weird behaviour.
2484 Irssi-silc client does support windows and can handle several
2485 connections without problems, see: www.irssi.org and SILC plugin.
2487 * Fixed some places where client was added to the IDList. The
2488 rule of thumb is following (in order to get everything right):
2489 If the client is directly connected local client then the
2490 `connection' argument must be set and `router' argument must be
2491 NULL to silc_idlist_add_client function. If the client is not
2492 directly connected client then the `router' argument must
2493 bet set and the `connection' argument must be NULL to the
2494 silc_idlist_add_client function.
2496 * The funtion silc_server_packet_send_local_channel actually did
2497 not check whether the client was locally connected or not. It
2498 does that now. Fixed a bug related to LEAVE command.
2500 * Fixed Remove Channel User payload parsing bug in server's
2501 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2503 * The server's silc_server_save_channel_key now checks also the
2504 global ID list for the channel as it might not be in the local
2505 list. Fixed a bug related to LEAVE command.
2507 * Is this the end of the [<unknown>] buglet that has been lurking
2508 around for a long time? A little for loop fix in server's
2509 silc_server_command_whois_parse that is used by both IDENTIFY
2510 and WHOIS command. At least, this was a clear bug and a cause
2511 of one type of [<unknown>] buglet.
2513 * WHOIS and IDENTIFY commands call the function
2514 silc_server_command_[whois/identify]_check function even if
2515 we are not router server.
2517 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2519 * Added --with-gmp configuration option. If set the GMP
2520 is always compiled in the SILC source tree. If not set then
2521 it is checked whether the system has the GMP3 installed. If
2522 it has then the GMP won't be compiled (the system's headers
2523 and library is used), if it doesn't have it then the GMP is
2524 compiled in the SILC source tree.
2526 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2528 * Changed RSA private exponent generation to what PKCS #1
2529 suggests. We try to find the smallest possible d by doing
2530 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2531 not security fix but optimization.
2533 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2535 * Added new config entry [Identity] to fork the server and run
2536 it as specific user and group. A patch from Bostik.
2538 * Imported Dotconf configuration library into lib/dotconf.
2539 This will be used to create the SILC configuration files later.
2540 It will appear in the distsribution after this commit.
2542 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2544 * A big code auditing weekend happening. Auditing code for
2545 obvious mistakes, bugs and errors. Also, removing any code
2548 Removed files for being obsolete:
2550 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2551 inline in the file lib/silcutil/silcbuffer.h)
2553 o lib/silcutil/silcbufutil.c (the header has inline versions)
2555 Changed code to fix possible error conditions:
2557 o The buffer formatting routines now check that the destination
2558 buffer really has enough space to add the data. This applies for
2559 both buffer formatting and unformatting
2560 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2561 unformatting was changed to accomodate following rules:
2562 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2563 sent to the function while XXX_*STRING will not allocate or copy
2564 the data into the buffer. Instead it sets the pointer from the
2565 buffer into the pointer sent as argument (XXX_*STRING used to
2566 require that the pointer must be allocated already). This change
2567 makes this whole thing a bit more consistent and more optimized
2568 (note that the data returned in the unformatting with XXX_*STRING
2569 must not be freed now). The routines return now -1 on error.
2571 o Tried to find all code that use buffer_format and buffer_unformat
2572 and added return value checking to prevent formatting and
2573 especially unformatting errors and possible subsequent fatal
2576 o Changed ske->x and ske->KEY to mallocated pointers in
2577 lib/silcske/silcske.h. Fixed possible data and memory leak.
2579 o Added return value checking to all *_parse* functions. Fixed
2580 many memory leaks as well.
2582 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2583 so that buffer overflows would not happen. All code now also
2584 checks the return value as it can fail.
2586 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2588 * Added reconnection support to server if the normal server looses
2589 its connection to the router (for example if router is rebooted).
2590 The server performs normal reconnection strategy implemented
2591 to the server. Affected file silcd/server.c.
2593 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2595 * Added new packet type SILC_PACKET_SET_MODE that is used to
2596 distribute the information about changed modes (for clients,
2597 channels and clients channel modes) to all routers in the
2598 network. Updated the protocol specification accordingly.
2600 Added functions into silcd/packet_send.c and
2601 silcd/packet_receive.c: silc_server_send_set_mode,
2602 silc_server_set_mode.
2604 Added new files silcmode.[ch] into lib/silccore that implements
2605 the encoding and decoding of Set Mode Payload. Added new type
2606 SilcSetModePayload. Moved the definitions of different modes
2607 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2609 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2611 * Oops, a little mistake in server's connection authentication
2612 protocol. The protocol is not ended with FAILURE but with
2613 SUCCESS if the authentication is Ok. :) Affected file is
2616 * Implemented NICK_CHANGE notify handling in server in the file
2617 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2618 the local clients on the channel. After the changing nickname
2619 in router environment snhould work and the [<unknown>] nickname
2620 should appear no more.
2622 The silc_server_replace_id function that receives the Replace ID
2623 payload now sends the NICK_CHANGE notify type also in the file
2624 silcd/packet_receive.c
2626 * Changed WHOIS and IDENTIFY command to support the maximum amount
2627 of arguments defined in protocol specs (3328 arguments). This
2628 fixed a bug that caused problems when there were more than three
2631 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2633 * Added extra parameter, command identifier, to the
2634 silc_client_send_command so that explicit command identifier
2637 Changed that ID list routines uses specific command identifier
2638 when sending WHOIS/IDENTIFY requests to the server so that they
2639 can be identified when the reply comes back.
2641 Affected files lib/silcclient/command.[ch],
2642 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2644 * Added `sender' argument to silc_server_packet_send_to_channel
2645 to indicaet the sender who originally sent the packet to us
2646 that we are now re-sending. Ignored if NULL. Affected file
2647 silcd/packet_send.[ch].
2649 * Added some server statistics support in silcd/server_internal.h
2650 SilcServerStatistics structure and around the server code. Also
2651 send some nice statistics information when client is connecting
2654 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2656 * Fixed channel ID decoding in server's JOIN command reply in
2657 silcd/command_reply.c
2659 * Fixed braodcasting of replace ID payload to not to send it if
2660 we are standalone server in silcd/packet_receive.c.
2662 * Fixed all channel message sending routines to not to send
2663 packets to clients that has router set, since they are routed
2664 separately in the same function earlier. Affects file
2665 silcd/packet_send.c and all channel packet sending functions.
2667 * In USERS reply, res_argv[i] are not allocated, the table
2668 is allocated. Thus changed that free the table, not its
2671 * In server's whois_check and identify_check if the client is
2672 locally connected do not send any WHOIS commands - they are not
2675 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2677 * Fixed some minor bugs in client when sending WHOIS command. The
2678 arguments was in wrong order.
2680 * Removed statis function add_to_channel from server in
2681 silcd/command.c that was previously used with the joining but
2684 * Tested USERS command in router environment successfully with two
2685 routers, two servers and two clients.
2687 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * Reorganized the USERS command and command reply in client library
2690 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2691 When the command is given by user we register a pending command
2692 callback that will reprocess the command after the reply has been
2693 received from the server. When reprocessing the packet we then
2694 display the information. Thus, the USERS information is displayed
2695 now in the command callback instead of in the command reply
2696 callback. The processing of the command is same as previously
2697 when server has sent the command reply in the JOINing process.
2699 * Added to USERS command in silcd/command_reply.c to join the client,
2700 we didn't use to know about, to the channel after we've created
2701 a client entry for it. Also, for clienet we did know already still
2702 check whether it is on the channel or not and add it if not.
2704 * Removed silc_server_command_join_notify as the function and its
2707 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2709 * Changed the client's pending command handling to the same as the
2710 server's pending command handling. It is also now possible to
2711 execute command reply functions from other command reply
2712 function as the function callbacks for commands and command
2713 replies are one and same. The pending commands are not static
2714 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2715 in client connection context. Thus, pending commands are server
2716 connection specific as it is convenient.
2718 Changed the function silc_client_command_pending and
2719 silc_client_command_pending_del and added new function
2720 silc_client_command_pending_check. Removed the
2721 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2724 * Added cmd_ident, current command identifier, to the client
2725 connection context in lib/silcclient/client.h to keep track on
2726 command identifiers used in command sending. Client's command reply
2727 function handling now supports the mandatory command identifiers.
2729 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2730 funtions in client to fully support pending command callbacks.
2732 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2733 as one of the arguments to the application in the command reply
2736 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2737 before first releasing SILC but came back. Now it is removed again
2738 and should come back nomore. The FORWARDED flag was used only
2739 by the JOINing procedure by forwarding the command packet to router.
2740 Now, the JOINing procedure has been changed to more generic (due
2741 to various router environment issues) and FORWARDED is not needed
2742 anymore for anything. The protocol specification is yet to be
2745 Now, removed silc_server_packet_forward from server and the flag
2746 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2748 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2750 * Renamed NAMES command to USERS command. The NAMES was named that
2751 due to historical reasons. Now it is renamed. Also, rewrote
2752 parts of the USERS command. The nickname list is not sent anymore
2753 by the server. Only Client ID and mode lists are sent in the USERS
2754 command. Changed this also to the protocol specification.
2756 The client now resolves the names and stuff after it receives
2757 the USERS list from the server when joining to the channel.
2759 * WHOIS and IDENTIFY commands has been changed to support multiple
2760 Client ID's per command. One can now search for multiple users
2761 in the network by sending only one WHOIS or IDENTIFY command.
2762 Changed the code and the protocol specifications.
2764 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2765 uses silc_server_command_whois_parse to parse the request. */
2767 * If normal server, do not parse the WHOIS and IDENTIFY requests
2768 before sending it to the router. Saves some time.
2770 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Fixed JOIN command on client library. Wrong number of arguments
2773 used to crash the client.
2775 * Added silc_server_channel_has_global function to check whether
2776 channel has global users or not.
2778 * Added silc_server_channel_has_local function to check whether channel
2779 has locally connected clients on the channel.
2781 * The silc_server_remove_from_one_channel now checks whether the
2782 channel has global users or not after given client was removed from
2783 the channel. It also checks whether the channel has local clients
2784 on the channel anymore. If it does not have then the channel entry
2785 is removed as it is not needed anymore.
2787 * The silc_server_notify now checks on JOIN notify whether the joining
2788 client is one of locally connected or global. If it is global then
2789 the channel has now global users on the channel and that is marked
2790 to the channel entry. Also, it now saves the global client to
2791 global list who is joining and JOINs it to the channel. This is
2792 for normal server, that is.
2794 Changed silc_server_send_notify_on_channel,
2795 silc_server_packet_relay_to_channel and
2796 silc_server_packet_send_to_channel check if we are normal server
2797 and client has router set (ie. global client) do not send the
2798 message to that client, as it is already routed to our router.
2800 * Implemented LEAVE notify type handling in silc_server_notify
2803 * Tested LEAVE command in router environment successfully. Tested
2804 with two routers, two servers and two clients.
2808 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2810 * Implemented SIGNOFF notify type handling in silc_server_notify
2813 * silc_server_remove_id now removes the client entry from all channels
2814 it has joined and thusly sends SIGNOFF notify type.
2816 * Rewrote the NAMES list generation in server by removing two excess
2817 loops. The lists are created now inside one loop.
2819 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2821 * silc_server_remove_channel_user checks now also global list
2822 for channel and client.
2824 * silc_server_new_channel_user checks now both local and global
2825 list for channel and client. Fixed a bug in client id decoding.
2826 Used to decode wrong buffer.
2828 * silc_server_channel_message checks now both local and global
2829 list for channel entry.
2831 * Tested channel joining (hence JOIN) in router environment
2832 successfully. Tested with two routers, two servers and two
2835 * Tested channel message sending in router environment successfully.
2837 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2839 * Added silc_server_save_channel_key into server.[ch] to save the
2840 received channel key in Channel Key payload processing. It is
2841 also used in JOIN command reply handling.
2843 Equivalent function silc_client_save_channel_key added into
2844 client.[ch] into client library.
2846 * Changed JOIN command reply to send information whether the channel
2847 was created or not (is existing already) and the channel key
2848 payload. Changed protocol specs accordingly.
2850 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2851 the request was sent by ID and not by nickname. Crashed on
2854 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2857 now correctly save the received data.
2859 * silc_server_free_sock_user_data now notifies routers in the
2860 network about entities leaving the network.
2862 At the same time implemented functions silc_server_remove_id
2863 and silc_server_send_remove_id to receive and send REMOVE_ID
2864 packets. The packet is used to notify routers in the network
2865 about leaving entities. The ID removed will become invalid in
2868 * Added function silc_idlist_del_server into server. Removes and
2869 free's server entry from ID list.
2871 * silc_server_private_message function now checks, if we are router,
2872 that the destination ID really is valid ID, naturally.
2874 * In router when NEW_ID packet is received (for new client) the
2875 hash of the Client ID is saved in the ID Cache but the
2876 client->nickname is set to NULL, instead of putting the hash
2879 IDENTIFY command now also checks that client->nickname must be
2880 valid. If it is not if will request the data from the server who
2881 owns the client. Added new function
2882 silc_server_command_identify_check.
2884 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2885 to set the command to already allocated Command Payload.
2887 * Tested private message sending in router environment with two
2888 routers, two servers and two clients. Fixed minor bugs and now
2891 * Fixed segfault from client's NAMES command. Used to crash if
2894 * Forwarded packets must not be routed even if it is not destined
2895 to the receiver. Changed server code comply with this.
2897 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2899 * Added `require_reverse_mapping' boolean value to ServerParams
2900 structure. If TRUE (not default) the server will require that
2901 the connecting host has fully qualified domain name.
2903 If the reverse mapping is not required and hostname could not be
2904 found the IP address is used as hostname.
2906 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Implemented version string checking to both client and server.
2909 The check is incomplete currently due to the abnormal version
2910 strings used in development version of SILC.
2912 * Changed all command functions in server to use the new
2915 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2917 * Changed char *data to unsigned char *data in ID Cache system to
2918 support binary data as ID Cache data. Changed code to support
2919 binary data in lib/silccore/idcache.c.
2921 * Renamed silc_server_packet_relay_command_reply to
2922 silc_server_command_reply as it is normal packet receiving
2923 function. Rewrote the function to accept command replys for
2924 servers and not only for clients.
2926 * Mark remote router always as registered server if we are connecting
2927 to it. Otherwise, commands sent by the router to us are ignored.
2929 * All ID List find routines now returns the ID Cache Entry pointer
2930 as well if requested.
2932 * WHOIS command works now in router environment, tested with two
2933 routers, two servers and two clients.
2935 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2936 in router environment (as it is almost equivalent to WHOIS) but
2937 hasn't been tested thoroughly. Added new functions:
2939 silc_server_command_identify_parse
2940 silc_server_command_identify_send_reply
2941 silc_server_command_identify_from_client
2942 silc_server_command_identify_from_server
2944 * Disabled route cache adding because adding two different ID's with
2945 same IP replaces the old cache entry thus giving wrong route.
2946 The entry->router->connection is always the fastest route anyway
2947 so route cache may not be needed. Of course, new routes maybe
2948 established after receiving the ID when the entry->router->connection
2949 might not be anymore the most optimal.
2951 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Add route cache for received ID for fast routing.
2955 * Added silc_server_packet_route to route received packet on router
2956 that is not destined to us.
2958 * Renamed silc_server_get_route to silc_server_route_get.
2960 * Added id_string and id_string_len fields into SilcServer to
2961 include encoded ServerID for fast comparing without excess
2962 encoding of the ID's.
2964 * Cleaned up WHOIS command on server side. Added following static
2967 silc_server_command_whois_parse
2968 silc_server_command_whois_check
2969 silc_server_command_whois_send_reply
2970 silc_server_command_whois_from_client
2971 silc_server_command_whois_from_server
2973 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2974 arguments in command replies. All command functions should be
2975 updated to use this macro.
2977 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2979 * Minor typo fixes on command reply handling on server.
2981 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * Added silc_server_command_add_to_channel internal routine to add
2984 the client to the channel after router has created the channel and
2985 sent command reply to the server.
2987 * Added generic silc_server_send_command to send any command from
2990 * Use static buffer with ID rendering instead of duplicating data.
2992 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * Fixed a channel user mode bug when joining to a channel server gave
2995 everybody channel founder rights, oops.
2997 * We mark ourselves as the router of the incoming server connection
2998 if we are router ourselves. This way we can check in some packet
2999 sending functions whether it is locally connected server. For
3000 incoming router connections we put NULL.
3002 * For router sending packets locally means now always sending the
3003 packet cell wide; to local clients and local servers. For normal
3004 server sending packet locally means sending it to only local
3007 * Fixed the JOIN command to really work in router environment. If the
3008 channel is created it is always created by the router. Router is
3009 also responsible of making the initial joining to the channel,
3010 sending JOIN notify to the sending server and distributing
3011 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3012 does not exist server doesn't do anything else but forward the
3013 command to the router which performs everything.
3015 * Added silc_server_send_channel_key function to send the Channel Key
3018 * Added silc_server_create_channel_key to create new channel key. The
3019 channel key is now re-generated everytime someone joins or leaves
3020 a channel, as protocol dictates. Note: channel->key_len is the
3023 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3025 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3026 packet_receive.[ch] to separate packet sending and receiving
3027 routines. The server.[ch] now includes everything else including
3028 actual packet processing (writing and reading data) and other
3031 Renamed silc_server_private_message_send_internal to
3032 silc_server_send_private_message. The routine is still though
3033 used only to relay private messages as server does not send
3034 private messages itself.
3036 Renamed silc_server_new_channel to silc_server_create_new_channel
3037 and added new function sicl_server_new_channel that handles the
3038 incoming New Channel packet. Added also new sending function
3039 silc_server_send_new_channel to send New Channel Payload.
3041 * Added new function silc_server_notify to process incoming notify
3042 packet to the server/router. Server may then relay the notify
3043 to clients if needed.
3045 * Added new function silc_server_new_channel_user to process incoming
3046 New Channel User packet. Router will redistribute the packet and
3047 send JOIN notify to its local clients and locally connected servers
3048 if needed. Normal server will send JOIN notify to its local client
3049 on same channel when received this packet. Added also corresponding
3050 sending function silc_server_send_new_channel_user to sent the
3053 * Added boolean route argument to send_notif_to_channel and
3054 packet_send_to_channel functions to attempt to route the packet
3055 if it is TRUE and send only locally if it is FALSE.
3057 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3059 * silc_server_replace_id now broadcasts the received replace ID
3060 packet if it is not broadcast packet already. The router must
3061 broadcast to inform other routers about changed ID.
3063 * Added backpointer to server's router into SilcServer context in
3064 silcd/server_internal.h.
3066 * Fixed silc_server_packet_broadcast to send correct broadcast
3069 * The channel key is now distributed to the local client as soon
3070 as it is received from the router (in router environment) so that
3071 no other packet may be sent for the channel until client has
3074 * silc_server_remove_channel_user now broadcasts the received
3075 Remove Channel User packet if it is not broadcast packet already.
3076 The router must broadcast to inform other routers about removed
3079 * Added users field into SilcPacketContext that is a reference count
3080 of the context. One can increase the reference count by calling
3081 silc_packet_context_dup which is now changed to just increase the
3082 reference count instead of duplicating the data. The reference
3083 count is decresed by calling silc_packet_context_free that will
3084 free the data after the reference count hits zero.
3086 For now on the packet context and everything allocated into it
3087 (including the raw packet from network) must be freed by calling
3088 the new silc_packet_context_free function. Added also new function
3089 silc_packet_context_alloc that must be used now to allocate the
3090 context. This also means that if a routine is asynchronous from
3091 silc_[client/server]_packet_parse_type the packet context must
3092 be duplicated by calling silc_packet_context_dup. Otherwise it
3093 gets free'd after silc_[client/server]_packet_parse_type returns.
3094 Also, one must remember that if packet is duplicated then its
3095 reference count must be decresed by calling the free function as
3096 many times as it was duplicated.
3098 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3099 from both client and server.
3101 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * Made joining to a channel working in router environment.
3105 * Cleaned up JOIN command on server side and create function
3106 silc_server_command_join_channel internal routine to make the
3109 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * Changed silc_command_pending list to SilcDList. Also, added
3112 `ident' field to SilcServerCommandPending structure to identify
3113 the reply and to call correct callback.
3115 Added silc_server_command_pending_check function to replace the
3116 corresnponding macro. The silc_command_pending list is not
3119 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3120 to set identifier to previously allocated Command Payload. It
3121 is used to set identifier for command when resending Command
3124 * Added silc_command_payload_encode_payload to encode Command
3125 Payload buffer from SilcCommandPayload structure.
3127 * Added silc_argument_payload_encode_payload to encode Argument
3128 payload buffer from SilcArgumentPayload structure.
3130 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Changed WHOIS command to support router connection on server side.
3133 The whois request is always sent to router unless the server is
3134 standalone server. After server has received the reply from the
3135 router will it send the reply to the client.
3137 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3138 broadcast received broadcast packet. The function is used only
3139 by router. The broadcast packet is always sent to the router's
3142 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3143 render given ID to printable string, for log files for example.
3145 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Made basic router to router connections working. At least they
3148 can now connect to each other but nothing really works the way
3149 they are supposed - yet.
3151 * Added new initiator token to RouterConnection configuration
3152 file in silcd/serverconfig.[ch]. It is used to tell whether we
3153 are the initiator to the remote router or whether we'll expect
3154 the other end to connect.
3156 * Moved registering of listener task to silc_server_init, hence
3157 the server starts listenning as soon as it is run, even if it
3158 does not have connections to other routers. Let's see how well
3161 * Changed default connection retry timeouts for more suitable in
3164 * Removed cipher and such arguments from silc_idlist_add_client
3165 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3166 Added new function silc_idlist_add_data to add the keys and stuff
3169 * Added SilcIDListData structure and added it to SilcClientEntry
3170 and SilcServerEntry as their first field in the structure. This
3171 way we can explicitly cast the ID entries to the SilcIDListData
3172 structure and get common data for the entries. In past, we had
3173 to first check what type of connection it is and then cast it to
3174 correct ID entry type. Now, we can directly cast the opaque
3175 pointer to the SilcIDListData (no matter what ID entry it actually
3176 is) and get the data needed.
3178 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3180 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3181 in some circumstances even if threre were timeout tasks, though not
3182 IO tasks, but tasks anyway. Now fixed.
3184 * Defined SilcServerConnection structure to hold connection specific
3185 stuff about directly connected servers and routers. The definition
3186 is currently in silcd/server_internal.h. I thought about having
3187 a bit more important role fro this struct but for now it is used
3188 only when connecting to other server (or router actually).
3190 * Added connecting retry support in server when connecting to
3191 router(s). The retry feature implement exponential backoff
3192 algorithm. Also, added SilcServerParams structure to hold default
3193 parameters for server. For now, it include these retry settings
3194 and are hard coded. After server is moded to be as Silc Server
3195 Library this structure will be more important.
3197 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * Changed client librarys channel->clients table to SilcList and
3200 changed code accordingly.
3202 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3204 * Changed client's channel table to SilcList and changed code
3205 accordingly. Also changed SilcChannelClientEntry to include back-
3206 pointer to the channel so that client entry can use that structure
3207 as list as well and we have fast cross-reference to the channel.
3208 This change dramatically decreased the complexity of channel
3209 handling with client entry and vice versa (removed one extra
3210 loop when searching for channel entry from many functions).
3212 * Changed server->sim from table to SilcDList and changed code
3215 * NAMES command can now be used from user interface. It will show
3216 the user list on the channel, neatly.
3218 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3219 Code now saves realname of the user if it becomes available.
3221 * Renamed configure.in to configure.in.pre and made ./prepare
3222 script to automatically add correct version string to
3223 configure.in which it creates from configure.in.pre.
3225 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * NAMES command reply now shows users mode with the nickname when
3230 * Moved silc_client_ch[u]mode[_char] functions from
3231 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3232 place sucks, they are utility functions and should be in some
3235 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3237 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3240 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * Added TRQ (efficient deque and list library) into lib/trq. This is
3245 a very good list library that is currently used in the SILC. Defined
3246 SilcList API over the library because I didn't like the API very
3247 much. See lib/trq/silclist.h for the API and examples of how to
3248 use the API. Fixed various places in the code to use the new
3249 SilcList API. The SilcList is meant for lists that has a structure
3250 already defined as a list. It is not suitable to add just some
3251 context to the list (in TRQ, the context is the list actually).
3253 So, I defined SilcDList that can be used for the purpose where
3254 predefined list structure does not exit. This can be used as
3255 such list. Now some context just can be added to the SilcDList.
3256 Currently this list is not used in the SILC just yet, though there
3257 are a lot places where this can replace dynamically allocated
3258 tables and I will fix these places, later, to use SilcDList.
3259 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3260 and use TRQ internally).
3262 Also fixed some annoying warning messages that the original TRQ
3263 code generated. Also minor changes to TRQ's Makefile.in.
3265 * Added support for querying by Client ID to both WHOIS and
3266 IDENTIFY commands into server, as required by the protocol.
3268 * Removed method function pointers from SilcBuffer structure. They
3269 weren't used to anything and just increased the context size for
3270 no good reason. This change also made silc_buffer_alloc and
3271 silc_buffer_free functions inline functions.
3273 * Disabled command flooding detection support until it's fixed so
3274 that it accepts commands in but does not execute them more than once
3277 * Added silc_net_localhost(), to return local hostname, into
3278 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3279 that must be initialized before calling silc_client_init.
3281 * Added new function: silc_server_send_notify_on_channels to send
3282 notify messages to all channels client has joined. It is assured
3283 that the message is sent only once per client.
3285 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3286 lib/silcutil/silcutil.[ch] as silc_format function. The new
3287 function is generic and is used by server as well, not only by
3288 the logging routines.
3290 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3291 the provided version string was not acceptable. Added new function:
3292 silc_ske_check_version into lib/silcske/silcske.h. The function
3293 must be implemented by the application (client or server) and it
3294 does not reside in the SKE library. The function checks the version
3295 string remote end sent.
3297 * Added back pointers (to opaque context and to SilcSocketConnection)
3298 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3300 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3301 duplicate packet context structure.
3303 * Changed `notify' client operation to send same arguments as client
3304 receives from server except for ID's. ID's are mapped to correct
3305 ID entry and that is returned. Also, if channel entry is not sent
3306 by server but the notify is for channel the channel entry is sent
3307 to application (otherwise application doesn't know that it is for
3308 channel (library gets it from packet's Destination ID)).
3310 * Added silc_client_remove_from_channels into client library to
3311 remove a client from all channels it has joined to. Used when
3312 received SIGNOFF notify from server. Added also new function
3313 silc_client_replace_from_channels to replace old ID entry with
3314 new ID entry on all channels. Used when received NICK_CHANGE
3317 * Fixed ID Cache list handling in silc_idlist_get_client in
3318 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3319 to get (or query) client by ID.
3321 * Updated TODO list.
3323 * Added connection authentication status message defined by the
3324 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3325 support for these into the code in client and server side.
3327 * Added generic function silc_client_send_command to send any command
3328 with variable argument list. Application should use this function
3329 to send commands if the command functions provided by the library
3330 does not suite for the application's user interface needs.
3332 * Added new `failure' client operation. Application is notified about
3333 received failure packet if client is executing a protocol. In this
3334 case the protocol's execution has failed.
3336 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3337 is required by the protocol.
3339 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3340 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3343 * Added status flag to SilcSKE object to indicate realtime status
3344 of the SKE protocol.
3346 * Application receives now exactly same command reply arguments as
3347 the library receives from server. However, if ID is received the
3348 corresponding ID entry is returned to the application (eg. Client
3349 ID is mapped to correct SilcClientEntry entry and that is returned).
3350 Changed command_reply client operation due to this change.
3352 * Changed all ID's in commands and in command replys as ID Payloads.
3353 Change affected both client and server side codes.
3355 All ID's sent in SILC network (with execption of ID's in SILC
3356 Packet header) are sent in ID Payload to support variable length
3359 * Server now notifies nick changes and notifies all clients on
3360 the channels about the new nickname (about the new Client ID,
3363 * Implemented CMODE command to change channel modes. Supports all
3364 channel modes defined by the protocol specs except ban and invite
3365 lists. (Also, private channel key mode is supported but support for
3366 setting private channel key in client is missing, thus, this mode
3367 has no effect on client side (except that server requires that the
3368 client uses private channel key and normal channel traffic does not
3371 Also, invite mode works per se, but INVITE command does not work
3372 yet correctly, so you can set channel as invite only channel but
3373 inviting clients to the channel does not work (it is yet to be
3374 thought what's the best way to do it).
3376 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3377 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3378 Implemented CUMODE command to change user's mode on the channel.
3379 Supports all modes defined by the protocol specs.
3381 * Added NAMES command reply to return users modes on the channel.
3383 * Removed unnecessary and slow ciphers from lib/silccrypt.
3385 * Set SO_KEEPALIVE option to connection sockets by default.
3387 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3389 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3390 redefined the Notify Payload into protocol specs.
3392 * Added silc_id_payload_parse_id to get ID directly from raw
3395 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3398 accept searching by Client ID as well.
3400 * Added support for LEAVE and SIGNOFF notify types in client library.
3402 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3403 to parse ID Payload from raw data.
3405 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Added flags parameter into silc_ske_assemble_security_properties
3408 function in lib/silcske/silcske.[ch].
3410 * Changed notify client operation to fit better for notify messages
3411 sent by server. The notify payload received from server is now
3412 passed to the application (after parsing it to SilcNotifyPayload).
3413 It is application's responsibility to retrieve the arguments
3414 from the payload and show the message the way it wants. The message
3415 sent by server is implementation specific.
3417 * Changed public keys to comply with the protocol specification.
3418 Old public keys are not supported anymore and are not compatible.
3420 * Removed nickname from Channel Payload as the latest draft removed
3421 it. The client must resolve the nickname from the NAMES command
3422 reply received when it joined the channel.
3424 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3426 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3428 * Fixed some errors in protocol specification drafts.
3430 * Created lib/silccore/silcnotify.c to implement Notify Payload
3431 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3432 generic payloads described by protocol specifications. The file
3433 includes implementations for ID Payload and Argument Payload.
3435 * Changed Command Payload implementation to use the new Argument
3436 Payload. Changed command_xxxx_payload to command_payload_xxxx
3437 to comply with SILC coding conventions.
3439 * Added suppport for Argument Payload handling in Notify Payload
3440 implementation as protocol requires it. Added the new support
3441 into server and client lib as well.
3443 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3445 * Added support for multiple nicknames on same channel. [n] is
3446 added locally to the nickname if there are more than one same
3447 nicknames on the channel.
3449 * Server now sends all nicknames that matched WHOIS request.
3450 Client also shows the list received from server.
3452 * Added TOPIC command to client side. User can now set and show
3453 current topic on channel.
3455 * Added MOTD command to client and server. Also, server sends the
3456 motd when client connects to the server.
3458 * Changed version strings to comply ISO 8601.
3460 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3462 * Fixed protocol error handling in client library. It should now
3463 cope even if the SKE fails for some reason.
3465 * Made new protocol specification drafts for submitting to IETF.
3467 * Implemented TOPIC command to server in silcd/command.c.
3469 * Added two new notify types into lib/silccore/silcnotify.h:
3470 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3471 notify nickname change and topic setting/change on a channel.
3473 * API change of command_reply operation in client library. The
3474 application gets now the status type received from server as well.
3476 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3480 * Cras fixed and optimized the packet handling even further and
3481 it should work now. Minor change to the prototype of function
3482 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3484 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Added new function into lib/silcutil/silcschedule.[ch]:
3487 silc_schedule_with_fd to select() a specified fd. The function
3488 returns after timeout expires or data arrives or goes. The
3489 function is used by packet routines to wait that all data is
3490 received from network.
3492 * Fixed data reading from network in lib/silccore/silcpacket.c.
3493 The code now assures that all data is read from the fd and then
3494 continues packet processing. This was a bug fix since the code
3495 used to drop some data in some circumstances.
3497 * Added new function into lib/silcclient/client.[ch]:
3498 silc_client_start_key_exchange to start key exchange after
3499 connection has been established to server. The code internally
3500 now uses this funtion but its main purpose was to provide it
3501 for applications that perform their own connecting. After
3502 application has created a connection it merely calls this
3503 function to start the key exchange between client and server.
3504 The library takes care of everything else after that.
3506 Updated also lib/silcclient/README to explain the usage of
3509 * Do not send to application information that connection has
3510 been established. Application gets notified it by connect
3513 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3515 * Applied cras's patch to add silc_schedule_one function. The
3516 function runs scheduler once and returns.
3518 * Fixed the scheduler after cras messed it up. The timeout
3519 handling works now as it's supposed to work.
3521 * Added into lib/silccore/ silcnotify.h to include notify
3522 message types support. Changed silc_server_send_notify*
3523 functions, in server.[ch], to support those new notify types.
3524 Added the support for the notify types into client library,
3525 as well. Added new notify client operation into ops.h in
3528 * Changed silc_server_packet_send_to_channel to send normal
3529 packets instead of just channel message packets. The function
3530 is now used to send the notify packets to channels. It is not
3531 used to send channel message packets anymore, as server never
3534 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3535 va_arg()s as it seems to require it nowadays. I guess, if SILC
3536 is compiled with older va_arg() the new code should work anyway.
3538 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * Splitted core library. Core library (lib/silccore) includes
3541 now only SILC protocol specific core (and common) components.
3542 Created new utility library (lib/silcutil) that includes more
3543 generic purpose stuff. The stuff for util library was taken
3544 from the old core library. This was minor and easy split.
3546 * Created SILC Client Library (lib/silcclient) that includes
3547 implementation of the SILC client without user interface. This
3548 was major move from silc/ directory. The code has been changed
3549 so that it is transparent towards the user interface. The
3550 silc/ directory includes now the same user interface as before
3551 and it uses the new client library. Read lib/silcclient/README.
3552 Basicly, the client library performs everything else related
3553 to SILC except user interface handling. Also, configuration
3554 files are considered to be part of user interface and library
3555 does not handle them.
3557 This change also changed a lot of structures, function naming etc.
3558 Most important change was that SilcClientWindow object was
3559 renamed to SilcClientConnection in the client library. Created
3560 also new file lib/silcclient/ops.h. Also added new files
3561 silc/local_command.[ch] and silc/client_ops.[ch].
3563 All these changes were made to make it easier for user interface
3564 designers to create what ever user interface for the SILC client
3567 It is also expected that the server will be moved to lib
3568 directory as well and SILC Server Library will be created;
3569 sometimes in the future.
3571 * Removed Local commands from lib/silccore/silccommand.h as
3572 they are application specific and new client library does not
3573 handle any of those anymore.
3575 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3576 old client implementation in silc/.
3578 * Added support for callback functions in SILC_LOG_* macros.
3579 Application can now set its own callbacks that will be called
3580 instead of using the default functions that will always print
3581 the debug messages to stderr (or stdout). Also, debugging can
3582 now be disabled by setting silc_debug to FALSE and re-enabled by
3583 setting it to TRUE. Note, that logging will still work even
3584 if debugging is disabled.
3586 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3587 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3588 silc_log_reset_debug_callbacks.
3590 * To enable debugging in silc client one must give now -d
3591 option on command line.
3593 * Changed silc_schedule_init to automatically allocate task queues
3594 if they are not allocated before calling it.
3596 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Added GMP 3.1 into math library.
3600 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3602 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3603 a channel in SILC network. The packet is used by servers and
3604 routers to notify other routers that user has left a channel.
3605 This little feature was missing until now. Added the feature
3606 to protocol specification as well.
3608 Added functions: silc_server_send_remove_channel_user and
3609 silc_server_remove_channel_user into server.[ch].
3611 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3612 lib/silccore/silcpacket.h. However, they are not implemented
3615 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3617 * Fixed joining to a channel and sending channel messages
3618 between server and router. The channel message sending should
3619 now work inside a cell.
3621 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3623 * Fixed the private message sending between server and router.
3624 The private message sending should now work inside a cell.
3626 * Added silc_server_replace_id into server.[ch] to replace
3627 existing ID in the SILC network.
3629 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3630 and silc_idlist_replace_server_id into idlist.[ch] in server.
3632 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Fixed the server to server connections. Server can again now
3635 connect to router. Router to router connections probably does
3638 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Added dynamic protocol registering support. Now protocols can
3641 registered and unregistered on the fly. Patch by cras.
3643 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Added lib/contrib directory to hold routines that some platforms
3646 don't have but are needed by SILC.
3648 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3649 into lin/contrib to provide getopt() and getopt_long() for
3650 those who don't have it.
3652 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Added AWAY command to client. When away message is set and
3655 client receives a private message packet the client automatically
3656 replies to the sender with the away message.
3658 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3659 bug seemed to be the cause of recent problems when compiling
3662 * Added version detection support to SKE protocol specification
3663 and added the new changes to the SKE implementation as well.
3664 There were other minor changes in the SKE protocol as well.
3666 Many changes in lib/silcske/silcske.[ch] and in
3667 lib/silcske/payload.[ch].
3669 * Added ^U functionality, clear input line. Patch from cras.
3671 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Mainly small bugfixes on core library. Fixed some debugging
3674 logging and buffer overflow in silclog.c.
3676 * Updated config.sub and config.guess on the distribution tree.
3678 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Added command lagging support in server. Client may execute
3681 commands now only once in two seconds.
3683 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3685 * Optimized packet reception. MAC computation and checking is now
3686 also more optimized. A lot previously duplicated code is now
3687 used as generic by both client and server.
3689 * Fixed key pair generation in clientutil.c
3691 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3693 * Added into lib/silccore/silcbufutil.[ch] new function;
3694 silc_buffer_realloc.
3696 * Moved generic packet sending/encryption functions to
3697 lib/silccore/silcpacket.[ch] from client and server. Some
3698 rewriting of the functions.
3700 * Moved all generic packet reception/decryption functions to
3701 lib/silccore/silcpacket.[ch] from client and server. The
3702 packet processing is now much cleaner in both client and server.
3703 These were major changes in both client and server.
3705 * Created many common functions in server to do packet sending.
3706 Previously code were duplicated a lot, this has been removed
3709 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * Rewrote major parts of the ID cache system. Don't know
3712 whether it is better now or not but at least the API is more
3715 * Major rewrite on ID cache stuff on client because of the ID
3716 cache API changes. Added idlist.c to client.
3718 * Also major rewrite on ID cache stuff on server as well.
3719 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3720 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3721 in hand, instead they are all put into the ID cache system now.
3722 All server_idlist_* routines uses ID cache now instead of
3723 traversing its own lists (those lists does not exist anymore).
3724 SilcIDList though still exists. Also, SilcXXXEntry's are
3727 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3729 * Finally made the SKE implementation compliant to the protocol
3730 specification. All mp integers are now binary encoded as
3731 opposed being HEX encoded.
3733 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3736 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3737 functions: silc_[encode/decode]_pem. Also added function
3738 silc_encode_pem_file to PEM encode with newlines ('\n') for
3741 * SILC public keys are now encoded either PEM or binary. Same
3742 option is for private keys as well. By default private keys
3743 are binary encoded and public keys PEM encoded. Silly HEX
3744 encoding were removed.
3746 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3747 function to create fingerprints.
3749 * Fixed a bug in SHA1; does not change the original data anymore.
3751 * Partly implemented INFO command on client and server side.
3752 Fixed CLEAR command. Changes to SERVER command; show current
3753 server(s) when giving command without arguments. Added
3754 VERSION command to client.
3756 * Added check to server that unregistered connections cannot
3757 execute commands (unless it is specificly allowed).
3759 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Fixed screen refresh.
3763 * Fixed channel joining bug from client. On some circumstances
3764 client tried to join to a channel it had already joined.
3766 * Added public key verification process into client's protocol.c.
3767 The client now verifies the public key from user and saves
3768 it into ~./silc/serverkeys/ directory.
3770 Added into: clientutil.[ch]: silc_client_verify_server_key.
3772 * Changed SKE protocol's silc_ske_initiator_finish function
3773 to accept callback function that verifies the received public
3774 key. Removed old silc_ske_verify_public_key function.
3776 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3778 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3779 silc_pkcs_private_key[_data]_set.
3781 * Made the password and public authentication more cleaner in
3782 server's protocol.c.
3784 * Removed historic and obsolete protocol `channel_auth' from
3785 both client and server.
3787 * Removed wrong way of sending command status messages from
3788 server to client in server's command.c. The old way violated
3789 protocol specification.
3791 Changes to silccore/silccommand.[ch]: removed
3792 silc_command_encode_status_payload -> not needed anymore,
3793 changed silc_command_encode_payload_va to accept extra
3794 argument on variable argument list. The argument type must
3795 now be provided to the function. Also, added new function:
3796 silc_command_encode_reply_payload_va which is same as
3797 normal command_encode_payload_va except command status type
3798 is provided as extra argument.
3800 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3802 * Added ~./silc directory handling. The directory includes the
3803 public and private keys for the client.
3805 Added silc_client_check_silc_dir, silc_client_create_identifier
3806 and silc_client_load_keys.
3808 * Implemented SILC protocol compliant public key. Added public
3809 and private key saving to and loading from files.
3811 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3812 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3813 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3814 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3815 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3817 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3818 silc_pkcs_load_[public/private]_key.
3820 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Added silc_server_get_route (route.[ch]) to get connection
3823 data for the fastest route for given ID.
3825 * Implemented INVITE command on client and server. The command
3826 were re-defined in the SILC Protocol Specification and the
3827 implementation now complies with the specification.
3829 * Implemented PING command on client and server.
3831 * Implemented NAMES command on client and server. The server side
3832 supports currently only normal server not router server yet.
3833 Some changes to NAMES definition in SILC protocol specification.
3835 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3837 * Implemented LEAVE command on client and server.
3839 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3840 again. This change was made to the protocol as well. Server
3841 should not violate the protocol specification anymore.
3843 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3845 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3846 was tested. SOCKS4 was not but should work anyway.
