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.
7 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
9 * Minor changes to the ./prepare script to change the package
10 name according the distribution name to the configure.in.
12 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
14 * Created new distribution system. Added file `distributions'
15 that defines all the distributions that can be created out of
16 the SILC source tree. The ./prepare script now reads that
17 file to determine how to prepare the distributions. The
18 first argument to the ./prepare is the name of the distribution
19 and second is the version of the distribution. If given
20 without arguments it creates the default (toolkit) distribution
21 with the default version (defined in ./prepare).
23 All Makefile.am files that are subject to the distributions
24 are now named as Makefile.am.pre. These are ./Makefile.am
25 and lib/Makefile.am. Others may be changed later.
27 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
29 * Added invite list, ban list, some key management and connection
30 error message printing to module formats in the Irssi SILC client.
32 * Added new silc_client_set_away_message to set the away message
33 that is back to the person who sent private message. The
34 affected file lib/silcclient/silcapi.h and the
35 lib/silcclient/client_prvmsg.c.
37 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
39 * Fixed the private message sending in the Irssi SILC client,
40 added local command KEY to the Irssi SILC client.
42 Added key management and key agreement message formats to the
43 irssi/src/fe-common/silc/module-formats.[ch].
45 Added USERS (alias WHO) printing, server/router operator
46 indication and LIST command printing to the module formats.
48 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
50 * Fixed channel joining notify handling, cumode notify handling
51 from Irssi SILC client.
53 * Added SILC specific module-formats to the Irssi SILC client so
54 that SILC specific message hilighting, colors etc is possible.
55 Affected file irssi/src/fe-common/silc/module-formats.[ch].
57 Added channel mode, channel user mode, actions, notices,
58 whois and whowas printing to the the module-formats.c.
60 * Fixed a bug in channel deletion in the server. The channel
61 is not left to the cache even if the channel founder auth mode
62 is set when there are no users anymore on the channel. Affected
65 * The silc_net_localhost now resolves the entire hostname including
66 the domain name. Affected file lib/silcutil/silcnet.c.
68 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
70 * Changed the ask_passphrase client operation to be ascynchronous.
71 It has now a completion callback and a context that the
72 application must call after it has got the passphrase from
73 the user. Affected files lib/silcclient/silcapi.h,
74 lib/silcclient/protocol.c, lib/silcclient/command.c and
77 Added SilcAskPassphrase callback that the application calls
78 to deliver the passphrase to the library.
80 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
81 The public key verification and especially a certificate
82 verification is asynchronous procedure.
84 Added new SILC_SKE_STATUS_PENDING status to indicate the
85 request is pending and a callback will be called to finalize
88 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
89 indicate that remote end did not send its public key (or
90 certificate), even though we require it. Added check for this
91 condition in the SKE. This was a security bug, now fixed.
93 Defined new SilcSKEVerifyCbCompletion callback that is called
94 when the verification process is completed.
96 The affected files lib/silcske/silcske_status.h and
97 lib/silcske/silcske.[ch].
99 * Changed the verify_public_key client operation to be async
100 as well. Defined SilcVerifyPublicKey callback that is used to
101 indicate the success of the public key verification process.
103 Changed the server and client to use the new async client
106 * Changed the Irssi SILC client's internal scheduler to be called
107 twice as many times as it used to be. As a result the client
108 should be a bit faster now. Affected file is
109 irssi/src/silc/core/silc-core.c.
111 * Added support to Irssi SILC client of asynchronous public key
112 verification and passphrase inquiry. Affected file is
113 irssi/src/silc/core/silc-core.c.
115 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
117 * Do not say "You have left channel %s" in client library.
118 Moved it to the application. Affected files are
119 lib/silcclient/command.c and silc/client_ops.c.
121 * Fixed silc_client_get_clients. Command context was not
122 duplicated and was freed memory in the callback. Affected
123 file lib/silcclient/idlist.c.
125 * Do not say "you are now talking..." on JOIN command in the
126 client library. The appliation must handle it.
128 * Do not say ".. changed topic to" in command reply in the
129 client libary. The application must handle it.
131 * Fixed TOPIC command sending in the client library.
133 * Fixed a memory leak in silc_client_command_free in the file
134 lib/silcclient/command.c.
136 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
138 * Imported a modified version of Irssi client to the source tree.
139 The Irssi will be used to create a new client called
140 Irssi SILC. Imported to irssi/.
142 Added silc_core_init_finish function to the Irssi. Affected
143 file irssi/configure.in.
145 A lot changes in the Makefile.ams around the irssi tree.
147 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
149 * Do not rehash if the new size is same as the old size of the
150 hash table, in the silc_hash_table_rehash*. The affected file
151 lib/silcutil/silchashtable.c.
153 * Replaced hash_table_del_by_context calls from the server
154 (when channel->user_list and client->channels) to the
155 hash_table_del as it is sufficient and faster.
157 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
159 * Added silc_hash_table_list, silc_hash_table_get and the
160 SilcHashTableList structure to provide an alternative way to
161 traverse the hash table. The affected files are
162 lib/silcutil/silchashtable.[ch].
164 * Changed the server's idlist routines to use the hash table
165 routines to optimize the code.
167 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
169 * Replaced the client entry's `channel' list and channel entry's
170 `user_list' list to hash tables for optimized lookup. Changed
171 the code to use the hash table interface around the code.
172 Affected file lib/silcd/idlist.[ch].
174 * Added `auto_rehash' boolean argument to the function
175 silc_hash_table_alloc to indicate whether the hash table should
176 auto-rehash when it thinks is appropriate time. It will
177 increase the hash table size if the there is twice as much
178 entries in the table than the size of the table, and will
179 decrease the size if there are twice as less entries than
180 the size of the table.
182 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
184 * Fixed silc_xxx_get_supported to not crash at some circumstances.
186 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
188 * silc_idcache_purge_by_context deletes the entry now by context
189 as it is supposed to do. Affected file lib/silccore/idcache.c.
191 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
192 client is not anymore valid (WHOWAS givens the info) and not
193 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
195 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
197 * Removed the `data' and `data_len' arguments from the ID Cache
198 interfaces and added `name' argument. ID Cache does not handle
199 anymore the binary data only a names associated with given ID.
201 * When hashing a Client ID with silc_hash_id the entire ID is
202 not hashed anymore, instead only the hash of the Client ID is
203 hashed. This way we can access the Client ID from the cache
204 with Client ID but with the hash of the ID (which is a hash of
205 the nickname) as well without any difference in performance.
207 Added also silc_idcache_find_by_id_one_ext to do one on one
208 searching when we have the actual ID. Added also function
209 silc_hash_client_id_compare. The affected files are
210 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
212 * When hashing the name associated with a ID it is always done
213 in lowercase. This way we can access the cache without worrying
214 about case-sensitivity, even though, for example nicknames are
217 * Fixed a bug in server with channel message sending. It put
218 wrong ID type as destination ID. The affected file
221 * silc_idcache_del_by_context now deletes from all hash tables
222 by context. Affected file lib/silccore/idcache.c.
224 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
226 * Changed the client library to use the new ID Cache interface.
227 Changes around the source tree.
229 * Added silc_hash_table_rehash_ext to rehash with specific
230 hash function. Affected file lib/silcutil/silchashtable.[ch].
232 * Added silc_hash_string_compare to compare two strings in the
233 hash table. Affected file lib/silcutil/silcutil.[ch].
235 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
237 * Added new function silc_idcache_del_by_context into the
238 lib/silccore/idcache.[ch].
240 * Changed the server's ID list routines to use the new ID Cache
241 interface. Changes around the source tree.
243 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
245 * Added silc_hash_table_del[_by_context]_ext functions in to the
246 lib/silcutil/silchashtable.[ch].
248 Removed silc_hash_table_find_all* routines and added new
249 silc_hash_table_find_foreach to replace them.
251 Added silc_hash_table_replace_ext function as extended
252 replacing function. Separated the simple hash table interface
253 from the extended hash table interface in the file
254 lib/silcutil/silchashtable.h.
256 * Fixed minor bugs and changed it to use some of the new
257 hash table functions in lib/silccore/idcache.c
259 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
261 * Added new function silc_hash_table_find_all to return all keys
262 in the hash table by the specified key. As the hash table is
263 collision resistant it also makes it possible to have several
264 duplicate keys in the hash table. This function may be used to
265 find all of the keys from the hash.
267 Added user_context arguments to the SilcHashFunction,
268 SilcHashCompare and SilcHashDestructor to deliver user specified
271 Added new fuctions silc_hash_table_find[_all]_ext to do
272 extended lookup with specified hash and compare functions and
273 specified user contexts.
275 Added new function silc_hash_table_add_ext to add the key
276 with specified hash function and user context.
278 Added new function silc_hash_table_foreach to traverse all
279 entrys in the hash table. Added SilcHashForeach callback
282 Added new function silc_hash_table_del_by_context to delete
283 the entry only if the context associated with the key matches.
285 Affected files are lib/silcutil/silchashtable.[ch].
287 * Removed silc_hash_[server/client/channel]_id and added just
288 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
289 silc_hash_id_compare to compare two ID's using as the hash table
290 comparison function. Added also silc_hash_data to hash
291 binary data and silc_hash_data_compare to compare it.
293 * Removed silc_idlist_find_client_by_hash as it is not needed
294 anymore. Affected file silcd/idlist.[ch].
296 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
297 to use internally the SilcHashTable. The new ID Cache is a lot
298 faster than the old one. Some of the ID Cache interface was also
299 rewritten and obsolete and stupid functions were removed.
301 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
303 * Added entry_count field to the SilcHashTable to keep the number
304 of the entries in the table. Implemented the function
305 silc_hash_table_rehash. Added new function
306 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
308 Fixed a minor bug in silc_hash_table_free.
310 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
311 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
312 into the lib/silcutil/silcutil.[ch].
314 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
316 * Implemented a collision resistant hash table into the
317 lib/silcutil/silchashtable[ch]. See the header and the source
318 for the SilcHashTable API.
320 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
322 * Merged dotconf version 1.0.2 into lib/dotconf.
324 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Do not compile anything in lib/silcsim/* if the SIM support
327 is not enabled. The tree should now compile without problems
330 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
332 * Compiled the SILC under cygwin. Compiled and tested briefly
333 without problems. More tests needed. The SIMs didn't compile
336 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
338 * Fixed possible crash in silc_get_username in the
339 lib/silcutil/silcutil.c.
341 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
343 * Fixed a va_arg in silc/client_ops.c.
345 * Oops, RC5 routines were named AES and caused some problems
346 when not using SIM's. Affected file lib/silccrypt/rc5.c.
348 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
350 * Added new SilcIDIP structure into the lib/silccore/id.h and
351 replaced the old `ip' fields from all SILC ID's to that type.
352 This is a step towards IPv6 support.
354 The silc_id_get_len takes now the ID as an extra argument.
355 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
356 both IPv4 and IPv6 based ID's.
358 The affected files are lib/silccore/id.[ch] and other files
359 around the tree using these routines.
361 * Removed the ID length arguments in server from various
362 silc_server_send_notify_* routines -> they are not needed
365 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
367 * Fixed memory leak in silc_encode_pem_file in the file
368 lib/silcutil/silcutil.c.
370 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Check minor version as well in the SKE. Affected files are
373 silcd/protocol.c and lib/silcclient/protocol.c.
375 * Added --identifier option to the server so that an identifier
376 can be when creating the public key for the server. Affected
377 file is silcd/silcd.c.
379 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
380 lib/silccrypt/silcpkcs.c.
382 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
384 * Register default ciphers and stuff when using -C option with
385 the server. Affected file sildc/silcd.c.
387 * Put back the servers public key filename format, it is better
388 than the new one. For now, the client keys are saved with the
389 new filename format. The affected file silc/client_ops.c.
391 * Implemented the Cipher API for the rest of the ciphers that
392 did not implement it or implemented it the wrong way.
394 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
396 * Register default ciphers and stuff when using the -S option
397 in the client. Affected file silc/silc.c. Same also when
398 creating new key pair with -C option.
400 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
402 * Fixed the silc_verify_public_key client operation function to
403 save the public keys differently. The fingerprint is now
404 used as filename and not the hostname. This way also the
405 client keys are saved uniquely and not with hostnames. The
406 affected file is silc/client_ops.c.
408 * Trimmed the silc_hash_fingerprint function to remove extra
409 whitespaces from the end of the fingerprint. The affected
410 file is lib/silccrypt/silchash.c.
414 * Added silc_cipher_register_default function to register all
415 default ciphers. It can be used when configuration files
416 does not exist and the application does not want any specific
417 ciphers in any specific order.
419 The SilcDList is now used as silc_cipher_list dynamically
420 allocated cipher list. Removed the static list all together
421 and now all ciphers must be allocated to the dynamic list.
422 The silc_cipher_alloc routine was changed to check only the
425 All silc_cipher_* routines that used to return int returns
428 The affected files lib/silccrypt/silccrypt.[ch].
430 * The same thing was done to silc_hash_* as for silc_cipher_*
431 routines. Affected files lib/silccrypt/silchash.[ch].
433 * The same thing was done to silc_pkcs_* as for silc_cipher_*
434 routines. Affected files lib/silccrypt/silcpkcs.[ch].
435 Added also silc_pkcs_[un]register[_default] functions.
436 Removed the data_context from the PKCS API.
438 * Added silc_hmac_register_default function to register default
439 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
440 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
441 to unregister all hmacs at once.
443 * Register the default ciphers, hash functions, PKCSs and HMACs
444 if client's configuration file does not exist. The affected
447 * The client did not load the hash functions from the SIM
448 modules at all. Added support for this. Affected file is
451 * When decoding public key with silc_pkcs_public_key_decode, check
452 the supported algorithm only if PKCS are registered. Affected
453 file lib/silccrypt/silcpkcs.c. The same was done with the
454 silc_pkcs_private_key_decode.
456 * Fixed the SILC List routines to keep the list always in order.
457 It used to change the list's order when traversing the list but
458 not it preserves the order. Affected file lib/trq/silclist.h.
460 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
462 * Added the client library to use the SilcSocketConnection's
463 reference counter (by silc_socket_dup) to prevent the bug that
464 the socket object may be freed underneath async operation.
466 * The name resolv library checking fixes in the configure.in.pre.
469 * Created new version of the protocol drafts for future
470 development. The -03 drafts are the ones that will be changed
471 in the trunk now and the -02 will remain as they are.
473 * Send list of CUMODE notifys to the router when announcing
474 the channel users to the router. Affected file silcd/server.c.
475 If the router receiving channel founder CUMODE for a channel
476 that already has channel founder it will send CUMODE notify
477 to the sender to remove the channel founder rights from the
478 announced client. Affected file silcd/packet_receive.c.
480 * The CUMODE notify may now use Server ID as well as the entity
481 who changes the mode. Updated protocool specs.
483 * Updated INSTALL and README files.
485 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
487 * New web pages in the http://silc.pspt.fi. The pages was
492 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
494 * Implemented the [DenyConnectin] config section in the server.
495 Added silc_server_config_denied_conn to check whether incoming
496 connection is denied. Affected file silcd/serverconfig.[ch].
498 * Do not check the ports when checking the incoming configuration
499 data if the port is 0, meaning any. Affected file is
500 silcd/serverconfig.c.
502 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
504 * Fixed buffer overflow in silc_string_compare in the file
505 lib/silcutil/silcutil.c.
507 * Fixed double free in silc_server_command_leave in the file
510 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
512 * Fixed the version checking in the server. Affected file is
515 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
517 * Fixed the configuration data fetching when accepting new
518 connections in the server. Affected file silcd/server.c.
520 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
522 * Added `sender_entry' argument to the function
523 silc_server_packet_relay_to_channel so that we can check
524 whether some destination actually belongs to the same route
525 the sender belongs (ie, we must not resend the packet to the
526 sender). Affected file silcd/packet_send.[ch].
528 * Added `servername' field to the SilcClientEntry in the server
529 to hold the name of the server where client is from. Affected
530 file is silcd/idlist.h.
532 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
534 * Moved the channel message encrypting in the router betwen
535 router connections from silc_server_channel_message to the
536 silc_server_packet_relay_to_channel since we want to check
537 whether we have anybody channel before encrypting anything.
538 Affected files silcd/packet_[receive/send].c.
540 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
542 * Fixed the [AdminConnection] server config section to support
543 multiple entries. Affected file silcd/serverconfig.c.
545 * Added support into the server to check the validity of the
546 incoming connection before executing any KE or authentication
549 * The connection configuration is now saved to the KE and
550 connection auth protocol contexts and not fetched anymore in
551 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
553 * The local hosts listenning address and port is also resolved
554 now when starting the server. We want to have the socket object
555 to include the real address and port for the listener. Added
556 new function silc_net_check_local_by_sock into the files
557 lib/silcutil/silcnet.[ch].
559 * Fixed a broadcast bug in server -> do not broadcast if we
562 * Fixed a routing bug. Do not route broadcast packets ever.
563 Broadcast packets must be processed always and not routed since
564 they may be destined to some other host than yourself and thus
565 would get routed without no good reason. Affected file is
568 * Added function silc_server_config_is_primary_route to check
569 whether primary router connection has been configured (a router
570 configuration that we are initiating). If there is not, we
571 will assume that there is only two routers in the SILC network
572 and we will use the incoming router connection as our primary
573 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
575 * Changed the order of the broadcasting. Broadcast _after_ the
576 packet has been processed not before. Affected file is
579 * Fixed a [ClientConnection] parsing bug. The port was never
580 parsed correctly thus resulting to port 0. Affected file
581 silcd/serverconfig.c.
583 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
584 argument and did not set the broadcast packet flag. Affected
585 file silcd/packet_send.c. Fixed same bug in the function
586 silc_server_send_notify as well.
588 * If we receive NEW_ID packet for our own ID in the server, ignore
591 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
595 * Removed the nickname from the Private Message Payload.
596 Updated the code and the protocol specs.
598 * Updated protocol specs for submitting to the IETF.
600 * Tweaked the Random Number Generator a bit. Affected file
601 lib/silccrypt/silcrng.c. Exported a new function
602 silc_rng_[global]_add_noise which can be used to add more
605 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
607 * Do not parse packets with different timeout when protocol
608 is active -> may cause problem with rekey. Affected file
611 * When server receives signoff notify it must not create
612 new channel key if the client is on any channels since the
613 sender of the signoff notify will create it.
615 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
617 * Added printing of error messages during SKE protocol from the
618 failure packet sent by server during SKE. Affected file
621 * Removed the client's failure_callback handling with timeout
622 and handle it immediately when received.
624 * The SKE library returned wrong type in SUCCESS and FAILURE
625 packets. They must be 32 bit MSB not 16 bit MSB.
627 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
629 * Ok, rewrote the logic of the re-key and now it seems to work.
630 I tested it on high traffic with frequent re-keys without
631 problems. Added hmac_receive (and renamed hmac to hmac_send)
632 in SilcClientConnection in lib/silcclient/client.h and
633 in SilcIDListData in silcd/idlist.h. Also, removed the
634 SilcPacketParserContext's cipher and hmac fields as they are
635 not needed anymore and actually caused some problems when
636 the ciphers and hmac's changed underneath the packet parser.
638 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * If re-key protocol is active then process the incoming packets
641 synchronously since we must assure that icoming packets encrypted
642 with the old key is processed before the new keys is set to
643 use. This is true other packets than for REKEY packets.
644 Affected file silcd/server.c. The same was done to client library
645 as well, affected file lib/silcclient/client.c.
647 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
649 * Fixed bug in client and server to accept the force send if
650 the packet is send from silc_[server/client]_packet_process
651 function. Otherwise the packets are never delivered, oops.
653 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
655 * Disable force sending of packets when REKEY protocol is active.
656 We must assure that no packet is sent directly when rekey is
657 performed. All packets must be sent through packet queue.
658 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
659 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
660 function is silc_[server/client]_packet_send_real to check
663 * Replaced the SIM paths from example config files to
664 /usr/local/modules. Also, make install creates now
665 /usr/local/silc/logs directory to hold all the SILC server
668 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
670 * Made the configure.in.pre work on Solaris. Patch by salo.
672 * Made all ciphers compatible with non-x86 machines. Defined
673 CBC mode macros into lib/silccrypt/ciphers_def.h.
675 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
677 * Fixed the make install.
679 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
681 * When MAC computation fails the silc_packet_decrypt returned 0
682 even though it was supposed to return -1. Fixed this. The
683 affected file is lib/silccore/silcpacket.c.
685 * Do not replace the config files in /etc/silc (in make install)
686 if they already exist. Affected file ./Makefile.am.
688 * Do not send re-key packets immediately but through packet queue.
689 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
691 * Changed silc_net_check_host_by_sock to return FALSE if the
692 IP/DNS could not be resolved. Though, it returns the IP address
693 now even if it could not resolve it (but returns also FALSE).
694 Affected file lib/silcutil/silcnet.[ch].
696 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
698 * Added silc_pkcs_decode_identifier to decode the public key's
699 identifier. Affected file lib/silccrypt/silpkcs.[ch].
700 Added also silc_pkcs_free_identifier. Added also new context
701 SilcPublicKeyIdentifier.
703 * Added -S option to the silc client. It is used to dump the
704 contents of the specified public key file.
706 * Changed the PKCS api to return the public key length when
707 setting the public key.
709 * Fixed a fatal bug in the public and private key file loading.
710 Affected file lib/silccrypt/silcpkcs.c.
712 * Execute the packet parsing for client with zero (0) timeout
713 if the protocol is active. Affected file silcd/server.c.
715 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
717 * Made the key generation options to the silcd program. Added
718 -C option, equivalent to client's option.
720 * Added new [ServerKeys] config section to the server. It
721 configures the server's public and private key.
723 * Defined generic Public Key Payload into the protocol
724 specification to send specific type of public keys and
727 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
728 public key or certificate.
730 * Implemented the GETKEY command to the server and to the
731 client library and on user interface.
733 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
735 * Made preliminary `make install' work.
737 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
739 * Added SilcServerRekey context into silcd/idlist.h.
741 * Added the PFS support as defined in the specification to the
742 SKE protocol. Affected files lib/silcske/*.c.
744 * Added `ske_group' field to the SilcServerRekey context to hold
745 the number of the SKE group that is used with PFS in re-key.
746 Affected file silcd/idlist.h.
748 * Added PFS re-key support to the server. Affected file is
751 * Added silc_protocol_cancel to cancel execution of the next
752 state of the protocol. Affected file is
753 lib/silccore/silcprotocol.[ch].
755 * Added the re-key support with and without PFS to the client
756 library. Re-key is performed once in an hour, by default.
758 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
759 Added silc_client_rekey_callback and silc_client_rekey_final.
760 Affected files are lib/silcclient/protocol.[ch] and
761 lib/silcclient/client.[ch].
763 * Removed the `hmac_key' and `hmac_key_len' fields from the
764 SilcClientConnection structure; not needed. Affected file is
765 lib/silcclient/client.h.
769 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
771 * Do not ask whether user wants to use the negotiated private key
772 for private messages, just use it. Affected file is
773 silc/local_command.c.
775 * Added `send_enc_key' and `enc_key_len' fields to the
776 SilcIDListData structure since they are needed in the re-key
777 phase. Affected file is silcd/idlist.[ch].
779 * Implemented the simple re-key protocol into the server.
780 Affected files silcd/server.c and silcd/protocol.[ch]. The
781 re-key will be performed once in an hour, by default.
783 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
784 Added silc_server_rekey, silc_server_rekey_callback and
785 silc_server_rekey_final.
787 * Removed Tunneled flag from the protocol. Updated the code
788 and the specifications.
790 * Adde `pfs' field to the SilcIDListData to indicate whether
791 the PFS is to be performed in the re-key. Affected file is
794 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
796 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
797 int64 of at least the xintXX size. If void * is less that 4
798 bytes uint32 * will be used. Defined bool as boolean.
800 * Changed _ALL_ unsigned long and unsigned int to uint32,
801 unsgined short to uint16 in the source tree.
803 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
804 not handle clients that has entry->data.registered == FALSE.
805 They are not in the network anymore. Affected file is
808 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
810 * Implemented the sending of the SERVER_SIGNOFF notify in the
811 server. Affected file is silcd/server.c.
813 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
814 Added also silc_notify_payload_encode_args into the
815 lib/silccore/silcnotify.[ch].
817 * Implemented ther SERVER_SIGNOFF notify handling in the server.
818 Affected file silcd/packet_receive.c.
820 * Implemented the SERVER_SIGNOFF notify handling in the client
821 library. Affected file lib/silcclient/client_notify.c. Also,
822 implemnted the printing of the SERVER_SIGNOFF info to the
823 application. Affected file silc/client_ops.c.
825 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
826 if the deleting was successful. Affected file silcd/idlist.[ch].
828 * Added support for public key authentication in the connection
829 authentication protocol in the client library. Affected file
830 lib/silcclient/protocol.c.
832 * Changed the server's silc_idlist_get_clients_by_* interface
833 to support already allocated array so that new entries may be
834 added to pre-allocated array. Affected file silcd/idlist.[ch].
835 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
838 * All command reply functions in the server now calls the
839 pending command callback even if error occured. This way the
840 error will be delivered to the client as well. Affected files
841 silcd/command.c and silcd/command_reply.c.
843 * Fixed INFO command to return local server's info if no server
844 was provided. Affected file lib/silcclient/command.c.
846 * Removed RESTART command for good. Updated the code and the
849 * Rewrote parts of the task system. It is a bit simpler now.
850 Removed unsued task priorities. The affected files are
851 lib/silcutil/silctask.[ch].
853 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
855 * Moved the USERS printing from the library to the application.
856 Affected files lib/silcclient/command.c and silc/client_ops.c.
858 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
862 * Added channel key re-key support. The re-key is perfomed
863 only by the router and is done once in an hour. Added `rekey'
864 field to the SilcChannelEntry in the server. Affected files
865 silcd/server.c and silcd/idlist.h.
867 * Added silc_task_unregister_by_context into the file
868 lib/silcutil/silctask.[ch].
870 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
872 * Added SILC_UMODE_GONE mode to indicate when the client is not
873 present in the SILC network. Added also support to the local
874 command AWAY that will set this mode. Added support of showing
875 "xxx is gone" in WHOIS command. The USERS command shows the
878 * Fixed setting server and router operator privileges in the
879 server's UMODE command. Affected file silcd/command.c.
881 * Merged the SKE KE1 and KE2 payloads into one payload. The
882 new KE payload is equivalent to the old KE2 payload.
884 Cleaned up the SKE Start Payload parsing. It now uses the
885 simple buffer unformatting to do the parsing. A lot faster
888 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
889 to the SKE that is used to indicate whether both of the SKE
890 parties should perform authentication. By default only the
891 responder performs authentication. By setting this flag also
892 the initiator must do authentication. By default it is unset
893 since in normal SKE case, client to server connection, only
894 the responder should do authentication. When doing SKE between
895 two clients both should perform authentication. Updated the
896 code and the protocol specs.
898 * A little fix to IDENTIFY command in the server. Search the
899 client first by hash not nickname. Affected file is
902 * Fixed the silc_client_close_connection to support closing
903 the client to client connections wihtout deleting too much
904 data. Affected file lib/silcclient/client.c.
906 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
907 are received if protocol used to be active but is not anymore
908 the application would crash due to NULL pointer dereference.
909 Affected files silcd/server.c and lib/silcclient/client.c.
911 * Added `hash' field to the SilcClientConnection to include
912 the hash function negotiated in the SKE protocol.
914 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
915 to set the channel founder authentication data. A client can
916 claim the founder rights later by providing the authentication
917 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
918 This way the channel founder can regain the channel founder
919 privileges even it is left the channel. This works only on
920 local server and the client must be connected to the same
921 server to be able to regain the founder rights. Updated the
922 protocol specs accordingly.
924 Added support to the CMODE command in the client to set the
925 founder auth data. Read the README to see how to set it.
927 Added support to the CUMODE command to claim the founder
928 rights. Read the README to see how to do it.
930 Added support for the founder authentication to the Channel
931 Entry in the server. Affected file silcd/idlist.h.
933 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
934 server's CMODE command. Affected file silcd/command.c.
936 * Added the following new functions into lib/silccore/silcauth.[ch]:
937 silc_auth_get_method and silc_auth_get_data.
939 * The server now saves the remote hosts public key to the
940 SilcIDListData pointer. Affected file silcd/protocol.c.
942 * The normal server now does not remove the channel entry from
943 the cache if the founder authentication data is set. It used
944 to remove it if the founder was the last one on the channel on
945 the server and left the channel. The auth data is saved and
946 if the channel is re-joined later the old entry is used with
947 the old auth data. Affected files silcd/command_reply.c and
950 * Removed the `pkcs' field from the SilcIDListData structure
951 in the server; it is not used. Affected file silcd/idlist.h.
953 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
955 * Fixed packet processing on slow links. Partial packets were
956 never re-processed because the incoming data buffer was cleared
957 by the application. Application must not directly clear the
958 sock->inbuf, the packet processing routines handle it. Fixed
959 this in client library and in server.
961 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
963 * Fixed the WHOIS and IDENTIFY send reply function to really
964 check whether to send list or just one entry. Affected file
967 * Cleaned up the LEAVE command's channel key distribution. The
968 affected file silcd/command.c.
970 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
971 can enforce the channel mode as well. In that case the ID
972 includes the ID of the server. The code now enforces the
973 mode change if the router have different mode than the server.
975 * The notify client operation with CMODE_CHANGE notify can now
976 return NULL client_entry pointer if the CMODE was not changed
977 by client. Application must check for this.
979 * Added <Server ID> argument to INFO command to support server
980 info fetching by Server ID.
982 * Added silc_server_announce_get_channel_users to get assembled
983 packets of channel users of the specified channel. Affected
984 file silcd/server.[ch].
986 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
987 was freed underneath the ID Cache.
989 * Re-announce clients when the server received CHANNEL_CHANGE
990 notify from the router. Affected file silcd/packet_send.c.
992 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
995 crashed since it did not handle the fact that there is no cipher
996 called "3" and didn't check the error condition. Now fixed.
998 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
999 flag. It can be used to send message requests.
1001 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1003 * Implemented the RESTART command in the client.
1005 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1006 notice type messages. Added notice printing to the user
1009 * The channel keys are not re-generated if the channel's mode
1010 is PRIVKEY, ie private key on the channel exists. Affected
1011 files silcd/server.c and silcd/command.c.
1013 * Fixed a little bug in channel message delivery when channel
1014 private keys are set in the server. Affected file is
1015 silcd/packet_send.c.
1017 * Changed the setting on channel->on_channel = TRUE from the
1018 silc_client_save_channel_key to the JOIN command reply. The
1019 key payload is not received if the private channel key is set.
1020 Affected file lib/silcclient/command_reply.c and the
1021 lib/silcclient/client_channel.c.
1023 * When the CMODE_CHANGE notify is sent and the channel private
1024 key mode is removed the channel key must be re-generated in
1025 other cells as well. Added this support for the router in the
1026 silcd/packet_receive.c.
1028 * Added new local command NOTICE to send notice message on
1029 channel. Affected file silc/local_command.[ch].
1031 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1033 * Added new local command ME to the client. It is used to send
1034 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1035 some action. Affected file silc/local_command.[ch].
1037 * Changed channel_message and private_message client operations
1038 to deliver the message flags to the application. Added also
1039 the `flags' arguments to the silc_client_send_channel_message
1040 and silc_client_send_private_message functions. Affected file
1043 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1045 * Redefined the Private Message Payload to support private message
1046 keys and to support the new private message flags. Updated
1047 the protocol specs. Flags makes it possible to have for example
1048 CTCP style messages.
1050 * Added new type SilcPrivateMessagePayload and defined an API
1051 for it in the lib/silcclient/silcprivate.[ch].
1053 * Tested private message private keys successfully. Tested the
1054 private message key set, unset and list commands with the new
1057 * Redefined the Channel Message Payload to include the channel
1058 message flags (equal with private message flags) to support
1059 for example CTCP style messages.
1061 * Defined some of the message (for channel and private message)
1062 flags. Updated the protocol specs and added the flags to the
1063 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1065 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1067 * Added SilcKeyAgreementStatus type to the key agreement routines
1068 to indicate the current status and error if one occured.
1069 The status types are defined in the lib/silcclient/silcapi.h.
1071 * Added new local command KEY that is used to set and unset private
1072 keys for channels, set and unset private keys for private messages
1073 with remote clients and to send key agreement requests and
1074 negotiate the key agreement protocol with remote client. The
1075 key agreement is supported only to negotiate private message keys,
1076 it currently cannot be used to negotiate private keys for channels,
1077 as it is not convenient for that purpose.
1079 * Fixed a minor pending callback setting bug in the function
1080 silc_client_get_client_by_id_resolve, now the function works.
1081 Affected file lib/silcclient/idlist.c.
1083 * Added function silc_net_get_local_port to get local bound
1084 port by socket. Added to lib/silcutil/silcnet.[ch].
1086 * Added `sockets' and `sockets_count' fields to the SilcClient
1087 object. They hold the sockets of the listenning sockets in
1088 the client. Listenning sockets may be for example the key
1089 agreement server. Affected file lib/silcclient/client.[ch].
1090 Added functions the silc_client_add_socket and the
1091 silc_client_del_socket. They are exported to the application
1094 * Added ~./silc/clientkeys to support other client's public keys.
1096 * Renamed verify_server_key client operation to verify_public_key
1097 and added one argument to indicate the type of the connection
1098 (server, client etc.).
1100 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1102 * Added silc_server_connection_auth_request to handle the
1103 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1104 silcd/packet_receive.[ch].
1106 * Added silc_server_send_connection_auth_request into the
1107 silcd/packet_send.c to send the connection auth request packet.
1109 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1112 * Fixed the public key authentication in responder side in the
1113 server. The `auth_data' pointer includes the SilcPublicKey
1114 not the path to the public key. Affected file silcd/protocol.c.
1116 * Implemented the public key authentication in the initiator side
1117 in the server. Affected file silcd/protocol.c.
1119 * Removed the [RedirectClient] config section from the server
1120 configuration. Is not needed and I don't want to implement it.
1122 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1124 * Cleaned up the CMODE command in the server. It now works
1125 correctly and supports all the modes defined in the protocol.
1126 Affected file is silcd/command.c.
1128 * Added `hmac_name' field to the SilcChannelEntry in the server
1129 to hold the default HMAC of the channel. It can be set when
1130 creating the channel (with JOIN command). Affected files
1133 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1134 type to indicate the change of the current cipher and hmac
1135 on the channel. Client can safely ignore the <cipher> argument
1136 (if it chooses to do so) since the CHANNEL_KEY packet will
1137 force the channel key change anyway. The <hmac> argument is
1138 important since the client is responsible of setting the new
1139 HMAC and the hmac key into use.
1141 * Fixed the CMODE command in the client library as well.
1143 * Tested CMODE command in router environment successfully.
1145 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1147 * Show the version of the remote client (or server) when connecting
1148 to the server. It is logged to the log file. Affected file
1149 is silcd/protocol.c.
1151 * Fixed the KILLED notify handling in the client library. The
1152 client must be removed from all channels when receiving the
1155 Also, do not remove the client entry when giving the KILL
1156 command but when the KILLED notify is received.
1158 * Removed silc_idlist_find_client_by_nickname from the server.
1159 Not needed anymore. Affected files silcd/idlist.[ch].
1161 * Implemented the CHANNEL_CHANGE notify type handling to the
1162 server. Affected file silcd/server.c.
1166 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1168 * Added silc_server_send_notify_invite to send the INVITE
1169 notify between routers.
1171 * Implemented the INVITE command correctly to the server.
1173 * Implemented the INVITE notify type handling in the server.
1175 * Implemented the INVITE command to the client library and on the
1178 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1180 * Added function silc_server_get_client_resolve to find the
1181 client entry by ID from all ID lists and then resolve it
1182 (using WHOIS) if it cannot be found. Affected file is
1185 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * Implemented the BAN command to the client library.
1189 * The JOIN command in the server now checks the invite list
1192 * Changed the silc_command_reply_payload_encode_va and the
1193 silc_command_payload_encode_va to support that if argument is
1194 NULL it ignores and checks the next argument. Affected file
1195 lib/silccore/silccommand.c.
1197 * Added silc_server_send_notify_ban to send the BAN notify
1198 type between routers.
1200 * Chaned the silc_notify_payload_encode to support that if
1201 argument is NULL it ignores and checks the next argument.
1202 Affected file lib/silccore/silcnotify.c.
1204 * Tested ban lists in router environment successfully.
1206 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1208 * Implemented BAN command to the server, in silcd/command.[ch].
1210 * Removed the BAN and INVITE_LIST modes from the CMODE command
1213 * Added function silc_string_match to regex match two strings.
1214 Affected files lib/silcutil/silcutil.[ch].
1216 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Redefined parts of the SilcChannelEntry in the server to support
1219 the new ban and invite lists.
1221 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1223 * Redefined the INVITE command. The same command can be used to
1224 invite individuals to the channel but also to manage the invite
1225 list of the channel (to add to and remove from the invite list).
1226 Updated the protocol specs.
1228 * Added new command SILC_COMMAND_BAN that can be used to manage
1229 the ban list of the channel. Updated the protocol specs.
1231 * Removed the channel modes: the SILC_CMODE_BAN and the
1232 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1233 in the CMODE command. The equivalent features are now available
1234 using INVITE and BAN commands. Updated the protocol specs.
1236 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1237 in the network about change in the current ban list. The notify
1238 type is not used by the client.
1240 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1241 support the invite lists.
1243 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Added new function silc_string_regexify that converts string
1246 including wildcard characters into regex string that can
1247 be used by the GNU regex library. Added into the file
1248 lib/silcutil/silcutil.[ch].
1250 Added silc_string_regex_combine to combine to regex strings
1251 into one so that they can be used as one regex string by
1252 the GNU regex library. Added into the file
1253 lib/silcutil/silcutil.[ch].
1255 Added silc_string_regex_match to match two strings. It returns
1256 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1258 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1260 * Imported GNU regex to the soruce tree into lib/contrib.
1261 Fixed some compiler warning from the regex.c.
1263 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1265 * Fixed MOTD command in the server to work in router environment.
1267 * Fixed the MOTD command in the client library to support
1268 the server argument in the command.
1270 * Added `nickname_len' argument to the silc_idlist_add_client
1271 in the server, as the `nickname' argument may be binary data
1274 * Added silc_idlist_get_channels to return all channels from
1277 * Implemented LIST command to the server. Affected file is
1280 * Implemented the LIST command to the client library and on the
1283 * Added [<user count>] argument to the LIST command reply.
1284 With private channels the user count is not shown.
1286 * Updated TODO and README.
1288 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1290 * The client entry's data.registered must be TRUE even with
1291 global client entry on global client list. The data.registered
1292 is used to check whether the client is anymore in the network,
1293 for example with WHOWAS command so it must be valid.
1295 * Fixed the WHOWAS command in the server. It now actually works
1296 in router environment. Added function into silcd/command_reply.c
1297 silc_server_command_reply_whowas_save.
1299 * Added silc_idlist_purge function to the silcd/idlist.c
1300 to periodically purge the ID Cache.
1302 * Fixed INFO command in the server. It works now in router
1303 environment. Added <server name> argument to the INFO command
1304 reply. Updated the protocol specs.
1306 * Fixed minor bug in silc_idcache_purge to not purge if the
1307 expire value is zero.
1309 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1310 they were buggy because of the WHOWAS information.
1312 * Fixed local command MSG to handle the async resolving of
1313 the remote client properly. It used to fail the first MSG.
1314 Affected file silc/local_command.c.
1316 * Added `data_len' field to SilcIDCache context.
1318 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1320 * Update TODO. Todo in commands in the server.
1322 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1324 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1325 used by routers as broadcast packet to inform other routers
1326 about the changed user mode.
1328 Implemented the notify handling in the server. Affected file is
1329 silcd/packet_receive.c. Added the function
1330 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1332 * Added new generic Channel Payload and deprecated the New Channel
1333 Payload. The New Channel Payload is now the generic Channel
1336 * Added new argument `mode' to the silc_server_send_new_channel
1337 as it is required in the Channel Payload now.
1339 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1340 and created a new and real SilChannelPayload to represent the
1341 new generic Channel Payload. Implemented the encode/decode
1342 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1344 * Added silc_server_get_client_channel_list to return the list
1345 of channels the client has joined for WHOIS command reply.
1346 Affected file silcd/server.[ch].
1348 * Implemented the channel list sending in the WHOIS command reply
1349 in server and in the client.
1351 Implemented the channel list displaying on the user interface
1352 as well. Affected file silc/client_ops.c.
1354 * Added silc_channel_payload_parse_list to parse list of Channel
1355 Payloads. It returns SilcDList list of SilcChannelPayloads.
1356 Client for example can use this function to parse the list of
1357 channels it receives in the WHOIS command reply. The caller
1358 must free the list by calling silc_channel_payload_list_free.
1359 Affected files lib/silccore/silcchannel.[ch].
1361 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Added one new argument <user mode> to the WHOIS command reply
1364 to return the mode of the user in SILC. Updated the protocol
1367 Implemented it to the server and client.
1369 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1371 * Fixed the mode printing on the user interface on joining.
1372 Affected file silc/client_ops.c.
1374 * Implemented the UMODE command and user modes in general to the
1375 client library and to the user interface.
1377 * Implemented the UMODE command to the server.
1379 * The server now sends UNKNOWN_COMMAND error status if client sends
1380 unknown command. Affected file silcd/command.c.
1382 * All server commands now handle the command identifier the right
1383 way when sending the command reply to the client. The client can
1384 use to identify the command replies with the identifier.
1386 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Added silc_server_get_client_route to resolve the route to
1389 the client indicated by the client ID. Affected file is
1392 * Added silc_server_relay_packet as general function to relay
1393 packet to arbitrary destination. This deprecates functions
1394 like _send_private_message_key, _relay_notify etc. Affected
1395 file is silcd/packet_send.[ch].
1397 Removed silc_server_send_key_agreement,
1398 silc_server_send_private_message_key and
1399 silc_server_packet_relay_notify functions from the file
1400 silcd/packet_send.[ch].
1404 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1405 server. Affected file silcd/packet_receive.[ch].
1407 * Implemented the KILL command to the client. Implemented the
1408 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1409 Affected files lib/silcclient/command[_reply].c and
1410 lib/silcclient/client_notify.c. Implemented the KILL notify
1411 printing in the user inteface.
1413 * Fixed a lot silc_parse_nick memory leaks from the client
1414 library in the file lib/silcclient/command.c.
1416 * Changed the silc_server_send_notify_on_channels's `sender'
1417 argument from SilcSocketConnection to SilcClientEntry to
1418 check the sender as entry and not as connection object and not
1419 to send to the client provided as argument. The affected file
1420 is silcd/packet_send.[ch].
1422 * The notify packets that are destined directly to the client used
1423 to not to be processed by the server. Now changed that and the
1424 server processes all notify packets. After relaying the packet
1425 to the client the notify packet is processed in the server.
1427 * The silc_server_free_client_data now checks whether there is
1428 pending outgoing traffic for the client and purges the data to
1429 the network before removing the client entry.
1431 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1433 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1434 an client is killed from the SILC Network. Updated the protocol
1437 Added new function silc_server_send_notify_killed to the
1438 silcd/packet_send.[ch].
1440 * Added function silc_server_packet_relay_notify to relay notify
1441 packets that are destined directly to a client. In this case
1442 the server does not process the notify packets but merely relays
1443 it to the client. Affected file silcd/packet_send.[ch].
1445 Added also silc_server_packet_process_relay_notify to check
1446 whereto relay the notify. Affected file is
1447 silcd/packet_receive.[ch].
1449 * Implemented the KILL command to the server.
1453 * Added the backup schema desgined last fall to the protocol
1454 specs for everyone to see. The specification is in the
1455 *-spec-xx.txt draft and the packet type definitions for the
1456 backup routers is in *-pp-xx.txt draft. Thusly, added also
1457 new packet type SILC_PACKET_CELL_ROUTERS.
1459 * A big security problem in the implementation discovered. The
1460 signoff of an client did not cause new channel key generation
1461 which it of course should've done. The channel keys must be
1462 always re-generated when client leaves (or signoffs) the channel.
1463 The silc_server_remove_from_channels funtion now handles
1464 the channel key re-generation.
1466 * Added `sender' argument to the silc_server_send_notify_on_channels
1467 to not to send the client provided as argument. Affected file
1468 silcd/packet_send.[ch].
1470 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1472 * Implemented OPER and SILCOPER commands into the server and
1475 * Added silc_auth_verify and silc_auth_verify_data to verify
1476 the authentication directly from the authentication payload.
1477 It supports verifying both passphrase and public key based
1478 authentication. Affected file lib/silccore/silcauth.[ch].
1480 * Added `hash' field to the SilcIDListData structure. It is the
1481 hash negotiated in the SKE protocol. Affected file is
1484 * Slight redesigning of the SilcAuthPayload handling routines.
1485 Do not send SilcPKCS but SilcPublicKey as argument.
1487 * Implemented the public key authentication support to the
1488 serverconfig. The public key is loaded from the provided path
1489 and saved as authentication data to void * pointer. Thus,
1490 changed the unsigned char *auth_data to void *auth_data;
1492 * Fixed SHUTDOWN command to send the reply before the server
1493 is shutdown. :) Affected file silcd/command.c.
1495 * Fixed fatal bug in CONNECT command. The hostname was invalid
1496 memory and server crashed. Affected file silcd/command.c.
1498 * Fixed fatal bug in CLOSE command. The server_entry became
1499 invalid but was referenced later in the command. Affected file
1502 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1504 * Fixed fatal bug in failure packet handling. Server ignored
1505 the failure and thus crashed when it came.
1509 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1511 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1512 that the command may be executed only once in (about) 2 seconds.
1513 The old SILC_CF_LAG flag is same but allows command bursts up
1514 to five before limiting.
1516 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1517 server code. Various commands now includes the CF_LAG_STRICT
1518 flag to disallow any kind of miss-use of the command.
1520 * Fixed the silc_buffer_unformat to not to allocate any data
1521 if the length of the data is zero. It used to allocate the
1522 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1524 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1526 * Changed the format of AdminConnection configuration section
1527 in the server. Added username of the admin to the format.
1528 Affected files silcd/serverconfig.[ch].
1530 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1531 to return admin configuration data by host, username and/or
1534 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1536 * Implemented WHOWAS command to the server. Added the functions:
1538 silc_server_command_whowas_parse,
1539 silc_server_command_whowas_send_reply,
1540 silc_server_command_whowas_from_client and
1541 silc_server_command_whowas_from_server
1543 * Added <Client ID> argument to the WHOWAS command reply. Updated
1544 the protocol specs accordingly.
1546 * Implemented WHOWAS command and command_reply to the client
1549 Implemented the WHOWAS printing on the user interface.
1551 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1553 * Added new argument to the WHOWAS command reply, the real name.
1554 It is an optional argument. Updated the protocol specs.
1556 * Added SilcIDCacheDestructor callback that is registered when
1557 the SilcIDCache is allocated. The callback is called when
1558 an cache entry in the ID Cache expires, or is purged from the
1559 cache. Added into lib/silccore/idcache.[ch].
1561 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1562 to destruct the client entries when the cache entry expires.
1563 Other ID Cache's in server and in the client library ignores
1566 * If the ID Cache entry's `expire' field is zero then the entry
1567 never expires. Added boolean `expire' argument to the
1568 silc_idcache_add function in the lib/silccore/idcache.[ch].
1569 If it is TRUE the default expiry value is used.
1571 * Added silc_server_free_client_data_timeout that is registered
1572 when client disconnects. By default for 5 minutes we preserve
1573 the client entry for history - for WHOWAS command.
1575 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1577 * Added support to the server to enforce that commands are not
1578 executed more than once in 2 seconds. If server receives
1579 commands from client more frequently, timeout is registered
1580 to process the commands. Affected file silcd/command.c.
1581 Added new function silc_server_command_process_timeout.
1583 * Changed NICK_NOTIFY handling in client library to check that
1584 if the client's nickname was changed, so there is no need to
1585 resolve anything from the server.
1587 * Removed error printing from the WHOIS and IDENTIFY commands.
1588 If error occurs then it is ignored silently in the client library.
1589 The application, however, may map the received error to
1590 human readable error string. The application currently maps
1591 the NO_SUCH_NICKNAME error to string.
1593 * Made the command status message public to the application. Moved
1594 them from lib/silcclient/command_reply.c to
1595 lib/silcclient/command_reply.h. The application can map the
1596 received command status to the string with the
1597 silc_client_command_status_message function.
1599 * Added check to the server to check that client's ID is same
1600 as the Source ID in the packet the client sent. They must
1603 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1605 * Added dist-bzip hook to the Makefile.am to make bzip2
1606 compressed distributions.
1608 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Server now enforces the maximum length for the nickname and
1611 the channel as protocol specification dictates. 128 bytes for
1612 nickname and 256 bytes for channel name.
1614 * Moved the WHOIS printing to the application. The client libary
1615 does not print out the WHOIS information anymore, the application
1616 must do it. Renamed silc_client_command_reply_whois_print to
1617 the silc_client_command_reply_whois_save.
1619 The client's idle time is also sent to the application now, and
1620 the idle is shown on screen.
1622 * Added silc_client_command_reply_identify_save to save the
1623 received IDENTIFY entries.
1625 * Do not check for channel private keys in message sending and
1626 reception if the channel does not have the PRIVKEY mode set.
1627 Affected file lib/silclient/client_channel.c.
1629 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1631 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1632 just surfaced after chaning the JOIN procedure.
1634 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1636 * Added silc_client_get_clients_by_list to get client entries
1637 from Client ID list, that is returned for example by JOIN
1638 and USERS command replies. The application should use this
1639 function for example when JOIN command reply is received to
1640 resolve the clients already on the channel (library does not
1641 do that anymore as USERS command reply is not used in the JOIN
1642 procedure anymore). Affected files lib/silcclient/silcapi.h and
1643 lib/silcclient/idlist.c.
1645 * JOIN command reply and USERS command reply returns now SilcBuffer
1646 pointers instead of unsigned char pointers when returning
1647 the client list and mode list.
1649 * Added <Client ID> argument to the JOIN command reply, mainly
1650 for the server to identify for which client the command was
1651 originally sent. Updated protocol specs accordingly.
1653 * Added SilcDlist private_key pointer to the SilcChannelEntry
1654 in the client to support the channel private keys. Affected
1655 file is lib/silcclient/idlist.h.
1657 * Added SilcChannelPrivateKey argument to the function
1658 silc_client_send_channel_message so that application can choose
1659 to use specific private ke if it wants to. If it is not provided,
1660 the normal channel key is used, unless private keys are set.
1661 In this case the first (key that was added first) is used
1662 as the encryption key.
1664 * Implemented the support for channel private key handling.
1665 Implemented the following functions:
1667 silc_client_add_channel_private_key,
1668 silc_client_del_channel_private_keys,
1669 silc_client_del_channel_private_key,
1670 silc_client_list_channel_private_keys and
1671 silc_client_free_channel_private_keys
1673 Affected file lib/silcclient/client_channel.c.
1675 * Added the support for the private keys in the channel message
1676 sending and encryption and in the message reception and
1677 decryption. Affected funtions are
1678 silc_client_send_channel_message and silc_client_channel_message.
1680 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1682 * Added SKE's key verify callback to the client library's
1683 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1685 * Removed the statement that server (or router) must send USERS
1686 command reply when joining to the channel so that the client
1687 knows who are on the channel. Instead, the client list and
1688 client's mode list is now sent in the JOIN command reply to the
1689 client who joined channel. This is better solution.
1691 * Added function silc_server_get_users_on_channel and function
1692 silc_server_save_users_on_channel to the silcd/server.[ch].
1694 * Removed function silc_server_command_send_users from the
1697 * Do not show topic on the client library anymore. The topic is
1698 sent in the command reply notify to the application and the
1699 application must show the topic now.
1701 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1703 * Added client searching by nickname hash into the IDENTIFY and
1704 WHOIS commands in the server as they were clearly missing from
1705 them. Affected file is silcd/command.c.
1707 * Fixed a bug in private message receiving in the client library.
1708 The remote ID was freed and it wasn't supposed, now it is
1711 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1713 * Minor fix to the channel payload; allocate the data area, as it
1714 needs to be of specific length.
1716 * If the key agreement port is zero then the operating
1717 system will define the bound port. Affected files are
1718 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1720 * Added new function silc_channel_payload_decrypt into the file
1721 lib/silccore/silcchannel.[ch].
1723 * Moved the channel message etc, check from silc_packet_decrypt
1724 to applications. The library calls now a generic
1725 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1726 when the packet is either normal or special. This was done to
1727 allow more wide range of checking that was not allowed when
1728 the code was in library. Now applications can do virtually any
1729 checks to the packet and return to the library the decision how
1730 the packet should be processed. Affected files are
1731 lib/silccore/silcpacket.[ch].
1733 Added silc_server_packet_decrypt_check to the server and
1734 silc_client_packet_decrypt_check to the client library.
1736 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1737 to send with specified source and destination information.
1739 * Channel message delivery between routers was broken after the
1740 channel key distribution was fixed earlier. The channel key
1741 was used be to distributed to other routers as well which is not
1742 allowed by the protocol. Now this is fixed and channel keys
1743 really are cell specific and the channel message delivery between
1744 routers comply with the protocol specification.
1746 * Fixed various commands in server to check also the global list
1747 for the channel entry and not just the local list. The affected
1748 file silcd/command.c.
1750 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1752 * Added assert()s to buffer formatting and unformatting routines
1753 to assert (if --enable-debug) when error occurs. Affected
1754 file: lib/silcutil/silcbuffmt.c.
1756 * Changed to auto-reconnect to check whether the remote host is
1757 router and register the re-connect timeout if it is. It used
1758 to check that whether we are normal server, but router must do
1759 auto-reconnect with another router as well. Affected file
1762 * Removed the [<key len>] option from CMODE command as the cipher
1763 name decides the key length, nowadays. See the defined ciphers
1764 from the protocol specification.
1766 * Added [<hmac>] option to the CMODE command to define the HMAC
1767 for the channel. Added SILC_CMODE_HMAC channel mode.
1769 * Added [<hmac>] option for the JOIN command so that user can
1770 select which HMAC is used to compute the MACs of the channel
1773 * Added Hmac field to the Channel Message Payload. The integrity
1774 of plaintext channel messages are now protected by computing
1775 MAC of the message and attaching the MAC to the payload. The
1776 MAC is encrypted. Now, it is clear that this causes some
1777 overhead to the size of the packet but rationale for this is that
1778 now the receiver can verify whether the channel message decrypted
1779 correctly and also when private keys are set for the channel the
1780 receiver can decrypt the packet with several keys and check from
1781 the MAC which key decrypted the message correctly.
1783 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1784 lib/silccrypt/silccipher.[ch].
1786 * Added silc_hash_len to return the digest length into the
1787 lib/silcrypt/silchash.[ch].
1789 * Rewrote parts of Silc Channel Payload interface in the
1790 lib/silccore/silcchannel.[ch]. The encode function now also
1791 encrypts the packet and parse function decrypts it.
1793 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1795 * Fixed a minor formatting bug in the SKE's key material processing.
1796 It actually might have processed the keys wrong way resulting
1799 * Redefined the mandatory HMAC algorithms and added new algorithms.
1800 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1801 and hmac-md5 truncated to 96 bits. The mandatory is now
1802 hmac-sha1-96. Rest are optional (including the one that used
1803 to be mandatory). Rationale for this is that the truncated HMAC
1804 length is sufficient from security point of view and can actually
1805 make the attack against the HMAC harder. Also, the truncated
1806 HMAC causes less overhead to the packets. See the RFC2104 for
1809 * Added new [hmac] configuration section. The SKE used to use
1810 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1811 is of course wrong. The official names that must be proposed in
1812 the SKE are the ones defined in the protocol specification
1813 (hmac-sha1-96 for example). The user can configure any hmac
1814 using any hash function configured in the [hash] section. At
1815 least, the mandatory must be configured.
1817 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1819 * Added HMAC list to the SKE proposal list. It has now both
1820 hash algorithm list and HMAC list. This makes the protocol
1821 incompatible with previous versions. The SKE now seems to work
1822 the way it is supposed to work, for the first time actually.
1824 * Defined plain Hash algorithms to the protocol specification.
1827 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1829 * Implemented support for key agreement packets into the server.
1830 Added functions silc_server_key_agreement and
1831 silc_server_send_key_agreement. Other than these functions,
1832 server has nothing to do with this packet.
1834 * Added support for private message key packets into the server.
1835 Added functions silc_server_private_message_key and
1836 silc_server_send_private_message_key.
1840 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1841 called in the protocol's final callback instead in the END
1842 protocol state. This makes a little more sense and in the same
1843 time in client we can use the same protocol routines for normal
1844 key exchange and to key agreement packet handling as well.
1846 * Added to both client's and server's KE protocol context the
1847 SilcSKEKeyMaterial pointer to save the key material. We will
1848 bring the key material to the protocol's final callback by doing
1849 this. The final callback must free the key material.
1851 * Added SKE's packet_send callback into client's KE protocol
1852 context so that the caller can choose what packet sending function
1853 is used. This way we can use different packet sending when
1854 doing normal SKE when doing key agreement packet handling (in
1855 the key agreement packet handling we do not want to encrypt
1858 * Implemented the responder side of the key agreement routines
1859 in the client. The client can now bind to specified port and
1860 accept incoming key negotiation. The key material is passed
1861 to the application after the protocol is over.
1863 * Implemented the processing of incoming Key Agreement packet
1864 in the client. Added function silc_client_key_agreement to
1867 * Implemented the intiator side of the key agreement routines
1868 in the client. The client can now initiate key agreement with
1869 another remote client. The key material is passed to the
1870 application after the protocol is over.
1872 * Created client_keyagr.c to include all the key agreement
1875 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1876 SILC_TASK_CALLBACK except that it is not static.
1878 * Created client_notify.c and moved the Notify packet handling
1879 from the client.[ch] into that file.
1881 * Created client_prvmsg.c and moved all private message and
1882 private message key routines from the client.[ch] into that file.
1884 * Create client_channel.c and moved all channel message and
1885 channel private key routines from the client.[ch] into that file.
1887 * Changed silc_client_get_client_by_id_resolve to resolve with
1888 WHOIS command instead of IDENTIFY command, in the file
1889 lib/silclient/idlist.c.
1891 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1893 * Implemented the SKE's responder side to the Client library.
1895 * When FAILURE is received to the protocol do not trust it
1896 blindly. Register a timeout to wait whether the remote closes
1897 the connection as it should do it, only after that process the
1898 actual failure. This was changed to both client and server.
1900 * Added client_internal.h to include some of the structures
1901 there instead of client.h in lib/silcclient/.
1903 * Added function silc_task_unregister_by_callback to unregister
1904 timeouts by the callback function.
1906 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1908 * Some "Incomplete WHOIS info" errors has been appearing on the
1909 log files. Took away the entry->userinfo check from WHOIS
1910 reply sending. The entry->userinfo is now " " if client did not
1911 provide one. I thought this was fixed earlier but something
1912 is wrong still. Let's see if the error still appears.
1914 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Fixed a minor bug in the login when the channel key is
1917 re-generated in the server. It used to generate the key in
1918 wrong order and thus caused problems in the channel traffic.
1920 * Fixed a minor bug in channel key distsribution after
1921 KICK command. The key was not sent to the router even though
1924 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1926 * Added silc_ske_process_key_material_data as generic routine
1927 to process any key material as the SILC protocol dictates. The
1928 function is used by the actual SKE library but can be used by
1929 applications as well. This relates to the private message keys
1930 and the channel private keys since they must be processed the
1931 same way the normal SILC session keys. The protocol dictates
1932 this. Affected files: lib/silcske/silcske.[ch].
1934 Added also silc_ske_free_key_material to free the
1935 SilcSKEKeyMaterial structure.
1937 * Defined silc_cipher_set_key function to set the key for
1938 cipher without using the object's method function. The affected
1939 files: lib/silccrypt/silccipher.[ch].
1941 * Implemented silc silc_client_add_private_message_key,
1942 silc_client_add_private_message_key_ske,
1943 silc_client_del_private_message_key,
1944 silc_client_list_private_message_keys and
1945 silc_client_free_private_message_keys functions in the
1948 Added functions silc_client_send_private_message_key to send
1949 the Private Message Key payload and silc_client_private_message_key
1950 to handle incoming Private Message Key payload.
1952 * Added Cipher field to the Private Message Key payload to set
1953 the cipher to be used. If ignored, the default cipher defined
1954 in the SILC protocol (aes-256-cbc) is used.
1956 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1958 * Removed lib/silcclient/ops.h file.
1960 Redefined parts of the SILC Client Library API. Created new
1961 file silcapi.h that deprecates the ops.h file and defines the
1962 published Client Library API. Defined also private message key
1963 API and channel private key API into the file.
1965 This is the file that the application must include from the
1966 SILC Client Library. Other files need not be included by
1967 the application anymore.
1969 * Added new key_agreement client operation callback and also
1970 defined the Key Agreement library API for the application.
1972 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1974 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1975 is used by clients to request key negotiation between another
1976 client in the SILC network. If the negotiation is started it
1977 is performed using the SKE protocol. The result of the
1978 negotiation, the secret key material, can be used for example
1979 as private message key.
1981 Implemented the Key Agreement payload into the files
1982 lib/silccore/silauth.[ch].
1984 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1986 * Redefined ciphers for the SILC protocol. Added some new ciphers
1987 and defined the key lengths for the algorithms. Changed the
1988 code accordingly. The default key length is now 256 bits.
1990 * Fixed SKE key distribution function silc_ske_process_key_material
1991 when the key length is more than 128 bits. The default key
1992 length in SILC is now 256 bits.
1994 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1995 to indicate unsupported algorithm.
1997 * Renamed rijndael.c to aes.c and all functions as well.
1999 * Fixed a long standing channel key setting bug in client library.
2000 Weird that it has never surfaced before.
2002 * Fixed bug in channel deletion. If the entire channel is removed
2003 then it must also delete the references of the channel entry
2004 from the client's channel list as the client's channel entry and
2005 the channel's client entry share same memory.
2007 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2009 * Implemented CONNECT and SHUTDOWN commands in the client.
2011 * Implemented CLOSE command to the client.
2013 * Added the function silc_idlist_find_server_by_name into the
2014 files silcd/idlist.[ch].
2016 Added the function silc_idlist_find_server_by_conn into the
2017 files silcd/idlist.[ch].
2019 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2021 * DIE command was renamed to SHUTDOWN. Updated the both code
2024 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2025 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2027 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2030 * Added function silc_server_create_connection function to create
2031 connection to remote router. My server implementation actually
2032 does not allow router to connect to normal server (it expects
2033 that normal server always initiates the connection to the router)
2034 so the CONNECT command is only good for connecting to another
2037 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2039 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2040 or some other client was kicked from the channel.
2042 Implemented the handling of the notify type to both client
2045 Implemented silc_server_send_notify_kicked to send the KICKED
2046 notify. It is used to send it to the server's primary router.
2048 * Implemented the KICK command into server and client.
2050 * Added `query' argument to the silc_idlist_get_client function
2051 to indicate whether to query the client from server or not if
2054 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2055 to indicate that the client is not channel founder.
2059 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * Removed the rng context from SilcPacketContext structure and
2062 changed that the packet routine uses the Global RNG API.
2064 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * Added support for quit message that client can "leave" on the
2067 channel when it quits the SILC. It is ditributed inside the
2068 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2070 Added silc_server_free_client_data that will take the
2071 signoff message as argument.
2073 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2075 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Updated parts of the protocol specification to keep it up
2080 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2082 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2083 payloads in one packet.
2085 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2086 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2087 use now the new List flag.
2089 * Also deprecated the following packet types: REPLACE_ID,
2090 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2092 * Added list support for Notify packet in server.
2094 * Added silc_server_send_notify_channel_change to send the
2095 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2096 the silc_server_send_replace_id.
2098 * Added silc_server_send_notify_nick_change to send the
2099 NICK_CHANGE notify type. Deprecates the function
2100 silc_server_send_replace_id.
2102 * Added silc_server_send_notify_join to send the JOIN notify type.
2103 Deprecates the function silc_server_send_new_channel_user.
2105 * Added silc_server_send_notify_leave to send LEAVE notify type.
2106 Deprecates the function silc_server_send_remove_channel_user.
2108 * Added silc_server_send_notify_cmode and
2109 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2110 types. Deprecates the silc_server_send_set_mode function.
2112 * Added SERVER_SIGNOFF notify type to indicate that server has
2113 quit. This means that all clients on the channel from that
2114 server will drop. This can be also used when netsplit happens.
2116 Deprecated REMOVE_ID packet type since it is not needed anymore
2119 Added silc_server_send_notify_server_signoff to send the
2120 SERVER_SIGNOFF notify type. Deprecates the function
2121 silc_server_send_remove_id.
2123 Added also silc_server_send_notify_signoff to send the
2124 SIGNOFF notify type.
2126 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2127 SILC protocol from this day on. Changed the protocol
2128 specification as well.
2130 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2131 notify type. It is used between routers to notify about
2132 topic changes on a channel.
2134 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2137 * Partly updated the protocol specification to comply with the
2138 changes now made. It is still though a bit outdated.
2140 * The JOIN notify type now takes one extra argument <Channel ID>.
2141 The packet used to be destined to the channel but now the
2142 JOIN type may be sent as list thus it is impossible to
2143 destine it to any specific channel. By adding this argument
2144 it is again possible.
2146 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Added CREDITS file. The CHANGES and CREDITS file will appear
2149 in the distribution as well.
2151 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2153 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2154 types in the server's silcd/packet_receive.c.
2156 * Implemented CMODE and CUMODE to work in router environment.
2158 * Fixed minor encoding and decoding buglet from the
2159 lib/silccore/silcmode.c.
2161 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2164 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2166 * Changed all SilcConfigServer* and silc_config_server* to
2167 SilcServerConfig* and silc_server_config*, respectively.
2170 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Associated the ID (client or server ID) to the Authentication
2173 Payload to avoid any possibility of forging. Updated the
2174 protocol specification and the code accordingly.
2176 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * The RSA key length is now save to the RsaKey context in the
2179 key generation process in lib/silccrypt/rsa.c. The key length
2180 is now used to figure out the maximum size of the block allowed
2181 to be encrypted/signed.
2183 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2184 is equivalent to the silc_mp_mp2bin but does not allocate any
2187 * Changed silc_mp_mp2bin API to take length argument. If it is
2188 non-zero then the buffer is allocated that large. If zero, then
2189 the size is approximated using silc_mp_sizeinbase, which however
2192 * Created Global RNG API which is global RNG that application can
2193 initialize. After initializing, any routine anywhere in the
2194 code (including library) can use RNG without allocating a new
2195 RNG object. This was done to allow this sort of use of the
2196 RNG in code that has no chance to allocate RNG object. All
2197 applications currently allocate this and many routines in the
2198 library use this. Affected file lib/silccrypt/silcrng.[ch].
2200 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2201 it to use the Global RNG API.
2203 * Defined Authentication Payload into protocol specification that
2204 is used during SILC session to authenticate entities. It is
2205 used for example by client to authenticate itself to the server
2206 to obtain server operator privileges.
2208 Implemented this payload into the lib/silccore/silcauth.[ch].
2209 Implemented also routines for public key based authentication
2210 as the new protocol specification dictates.
2212 Moved definitions of different authentication methods from
2213 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2215 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2216 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2217 silc_pkcs_verify_with_hash functions into the file
2218 lib/silccrypt/silcpkcs.[ch].
2220 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2222 * The client entry's userinfo pointer must be always valid.
2223 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2224 will fail since it requires the userinfo. Now, the userinfo
2225 is allocated as "" if actual userinfo does not exist. Actually,
2226 it must exist and it is totally Ok to drop client connections
2227 that does not announce the userinfo. However, we will make
2228 this workaround for now.
2230 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2231 to return the remote port by socket.
2233 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2235 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2236 SILC_SERVER_PENDING_EXEC and added an new macro
2237 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2238 data or when error occurs while processing the pending command.
2240 Added new argument `destructor' into silc_server_command_pending
2241 and to the SilcServerCommandPending object. This destructor is
2242 now called after calling the pending callback or if error occurs
2243 immediately. If error occurs the actual pending callback won't
2244 be called at all - only the destructor. The destructor may be
2245 NULL if destructor is not needed.
2247 All this applies for client library code as well. Similar
2248 changes were made there as well for the pending commands.
2250 In the client, the application must now allocate the
2251 SilcClientCommandContext with the silc_client_command_alloc
2254 * Added reference counter to the SilcServerCommandContext. Added
2255 function silc_server_command_alloc and silc_server_command_dup
2258 Same type of functions added to the client library for the same
2261 * Removed the cmd_ident from IDListData away since it is now
2262 global for all connections. It is the command identifier used
2263 in command sending and with pending commands. The affected file
2266 * Added reference counter to the SilcSocketConnection objecet to
2267 indicate the usage count of the object. The object won't be
2268 freed untill the reference counter hits zero. Currently only
2269 server uses this, and client ignores it. The client must be
2270 set to use this too later. The affected files are
2271 lib/silccore/silcsockconn.[ch]. Added also the function
2272 silc_socket_dup to increase the reference counter.
2274 This was mainly added because it is possible that the socket
2275 is removed underneath of pending command or other async
2276 operation. Now it won't be free'd and proper DISCONNECTING
2277 flags, etc. can be set to avoid sending data to connection that
2278 is not valid anymore.
2280 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2281 the connection. After that it sets SILC_SET_DISCONNECTED.
2282 It is, however, possible that the socket data is not still freed.
2283 The silc_server_packet_process now checks that data is not
2284 read or written to connection that is DISCONNECTED. The socket
2285 get's freed when the reference counter hits zero.
2287 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2289 * Changed the client operation API: channel_message operation's
2290 `sender' is now the client entry of the sender, not the nickname
2291 and the `channel' is the channel entry, not the channel name.
2293 In the private_message operation the `sender' is now also the
2294 client entry of the sender not the nickname.
2296 Affected file is lib/silcclient/ops.h and all applications
2297 using the client operations.
2299 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2301 * Moved the calling of ops->connect() from connect_to_server_final
2302 into receive_new_id functin since that is the point when the
2303 client is actually allowed to send traffic to network. The
2304 affected file is lib/silcclient/client.c.
2306 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2308 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2309 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2310 (if needs broadcasting) instead of broadcasting the packets one
2311 by one which would make a burst in the network traffic.
2313 * Added `broadcast' argument to the functions in silcd/server.[ch]
2314 silc_server_create_new_channel[_with_id] to indicate whether
2315 to send New Channel packet to primary router.
2317 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2319 * Added new function into the silcd/server.[ch] files:
2320 silc_server_create_new_channel_with_id to create new channel with
2321 already existing Channel ID.
2323 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2324 lib/silccore/silcpacket.h. This packet is used t send list of
2325 Set Mode payloads inside one packet. Server uses this to set
2326 the modes for the channels and clients on those channels, that it
2327 announced to the router when it connected to it. The protocol
2328 specification has been updated accordingly.
2330 * The silc_server_new_channel did not handle the packet coming
2331 from normal server as it normally does not send that. However,
2332 when it announces its channels it does send it. Implemented
2333 the support for that.
2335 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2336 into the file lib/silccore/id.h.
2338 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Fixed memory leaks in the functions silc_idlist_del_client,
2341 silc_idlist_del_channel and silc_idlist_del_server in the file
2342 silcd/idlist.c. All of those leaked like a sieve.
2344 * Fixed some small memory leaks in the client's function
2345 silc_client_notify_by_server.
2347 * Added functions into silcd/server.c: silc_server_announce_clients,
2348 silc_server_announce_channels and silc_server_announce_server.
2349 These functions are used by normal and router server to announce
2350 to its primary router about clients, channels and servers (when
2351 router) that we own. This is done after we've connected to the
2354 These functions effectively implements the following packet types:
2355 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2356 and SILC_PACKET_NEW_ID_LIST.
2358 * Added new functions into the silcd/packet_receive.[ch]:
2359 silc_server_new_id_list, silc_server_new_channel_list and
2360 silc_server_new_channel_user_list to handle the incoming
2361 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2363 * Added support of changing Channel ID in the function
2364 silc_server_replace_id. If the server that announces a channel
2365 to the router already exists in the router (with same name but
2366 with different Channel ID), router is responsible to send
2367 Replace ID packet to the server and force the server to change
2368 the Channel ID to the one router has.
2370 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2371 client that the Channel ID has been changed by the router. The
2372 normal server sends this to the client. Client must start using
2373 the new Channel ID as the channel's ID.
2375 Implemented handling of this new type into lib/silcclient/client.c
2376 into the function silc_client_notify_by_server.
2378 * Added new function silc_idlist_replace_channel_id into the files
2379 silcd/idlist.[ch] to replace the Channel ID.
2381 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2383 * Call silc_server_command_identify_check always when processing
2384 the IDENTIFY command in silcd/command.c
2386 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2388 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2389 send keepalive packets. The packet can be sent by clients,
2390 servers and routers.
2392 Added function silc_socket_set_heartbeat into the file
2393 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2394 If not set, the heartbeat is not performed. The actual
2395 heartbeat is implemented in the low level socket connection
2396 library. However, application is responsible of actually
2399 Added silc_server_send_heartbeat to send the actual heartbeat
2400 packet into silcd/packet_send.[ch]. Server now performs
2401 keepalive with all connections.
2403 * Added silc_task_get_first function into lib/silcutil/silctask.c
2404 to return the timeout task with shortest timeout. There was a bug
2405 in task unregistration that caused problems. TODO has been
2406 updated to include that task system must be rewritten.
2408 * The client library will now resolve the client information when
2409 receiving JOIN notify from server for client that we know but
2410 have incomplete information.
2412 * Rewrote parts of silc_server_remove_from_channels and
2413 silc_server_remove_from_one_channel as they did not remove the
2414 channel in some circumstances even though they should've.
2416 * Encryption problem encountered in server:
2418 The LEAVE command used to send the Channel Key packet to the
2419 router immediately after generating it. However, the code
2420 had earlier sent Remove Channel user packet but not immediately,
2421 ie. it was put to queue. The order of packets in the router
2422 was that Channel Key packet was first and Remove Channel User
2423 packet was second, even though they were encrypted in the
2424 reverse order. For this reason, MAC check failed. Now, this
2425 is fixed by not sending the Channel Key packet immediately but
2426 putting it to queue. However, this is more fundamental problem:
2427 packets that are in queue should actually not be encrypted
2428 because packets that are sent immediately gets encrypted
2429 actually with wrong IV (and thus MAC check fails). So, packets
2430 that are in queue should be encrypted when they are sent to
2431 the wire and not when they put to the queue.
2433 However, the problem is that the current system has not been
2434 designed to work that way. Instead, the packet is encrypted
2435 as soon as possible and left to the queue. The queue is then
2436 just purged into wire. There won't be any fixes for this
2437 any time soon. So, the current semantic for packet sending
2440 o If you send packet to remote host and do not force the send
2441 (the packet will be in queue) then all subsequent packets to the
2442 same remote host must also be put to the queue. Only after the
2443 queue has been purged is it safe again to force the packet
2446 o If you send all packets immediately then it safe to send
2447 any of subsequent packets through the queue, however, after
2448 the first packet is put to queue then any subsequent packets
2449 must also be put to the queue.
2451 Follow these rules and everything works fine.
2453 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2455 * Added new function silc_server_remove_clients_by_server to
2456 remove all client entries from ID list when the server connection
2457 is lost. In this case it is also important to invalidate all
2458 client entires as they hold the invalid server entry. This
2459 fixes fatal bug when server has lost connection and will reconnect
2462 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2464 * Made some sanity checks to silc_server_daemonise like to check
2465 whether the requested user and group actually exists.
2467 * Added sanity check to SKE's silc_ske_responder_finish to check
2468 that the public and private key actually is valid.
2470 * Invalidate the client's nickname when receiving Replace ID
2471 packet and the Client ID is being replaced. This means that the
2472 server will query the nickname if someone needs it (client)
2475 * Sort the ID Cache in client library when the ID Cache data
2476 has changed (needs sorting).
2478 * Do not allow for SILC client to create several connections to
2479 several servers. The client does not support windows right now
2480 and generating multiple connections causes weird behaviour.
2482 Irssi-silc client does support windows and can handle several
2483 connections without problems, see: www.irssi.org and SILC plugin.
2485 * Fixed some places where client was added to the IDList. The
2486 rule of thumb is following (in order to get everything right):
2487 If the client is directly connected local client then the
2488 `connection' argument must be set and `router' argument must be
2489 NULL to silc_idlist_add_client function. If the client is not
2490 directly connected client then the `router' argument must
2491 bet set and the `connection' argument must be NULL to the
2492 silc_idlist_add_client function.
2494 * The funtion silc_server_packet_send_local_channel actually did
2495 not check whether the client was locally connected or not. It
2496 does that now. Fixed a bug related to LEAVE command.
2498 * Fixed Remove Channel User payload parsing bug in server's
2499 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2501 * The server's silc_server_save_channel_key now checks also the
2502 global ID list for the channel as it might not be in the local
2503 list. Fixed a bug related to LEAVE command.
2505 * Is this the end of the [<unknown>] buglet that has been lurking
2506 around for a long time? A little for loop fix in server's
2507 silc_server_command_whois_parse that is used by both IDENTIFY
2508 and WHOIS command. At least, this was a clear bug and a cause
2509 of one type of [<unknown>] buglet.
2511 * WHOIS and IDENTIFY commands call the function
2512 silc_server_command_[whois/identify]_check function even if
2513 we are not router server.
2515 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2517 * Added --with-gmp configuration option. If set the GMP
2518 is always compiled in the SILC source tree. If not set then
2519 it is checked whether the system has the GMP3 installed. If
2520 it has then the GMP won't be compiled (the system's headers
2521 and library is used), if it doesn't have it then the GMP is
2522 compiled in the SILC source tree.
2524 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * Changed RSA private exponent generation to what PKCS #1
2527 suggests. We try to find the smallest possible d by doing
2528 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2529 not security fix but optimization.
2531 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2533 * Added new config entry [Identity] to fork the server and run
2534 it as specific user and group. A patch from Bostik.
2536 * Imported Dotconf configuration library into lib/dotconf.
2537 This will be used to create the SILC configuration files later.
2538 It will appear in the distsribution after this commit.
2540 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2542 * A big code auditing weekend happening. Auditing code for
2543 obvious mistakes, bugs and errors. Also, removing any code
2546 Removed files for being obsolete:
2548 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2549 inline in the file lib/silcutil/silcbuffer.h)
2551 o lib/silcutil/silcbufutil.c (the header has inline versions)
2553 Changed code to fix possible error conditions:
2555 o The buffer formatting routines now check that the destination
2556 buffer really has enough space to add the data. This applies for
2557 both buffer formatting and unformatting
2558 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2559 unformatting was changed to accomodate following rules:
2560 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2561 sent to the function while XXX_*STRING will not allocate or copy
2562 the data into the buffer. Instead it sets the pointer from the
2563 buffer into the pointer sent as argument (XXX_*STRING used to
2564 require that the pointer must be allocated already). This change
2565 makes this whole thing a bit more consistent and more optimized
2566 (note that the data returned in the unformatting with XXX_*STRING
2567 must not be freed now). The routines return now -1 on error.
2569 o Tried to find all code that use buffer_format and buffer_unformat
2570 and added return value checking to prevent formatting and
2571 especially unformatting errors and possible subsequent fatal
2574 o Changed ske->x and ske->KEY to mallocated pointers in
2575 lib/silcske/silcske.h. Fixed possible data and memory leak.
2577 o Added return value checking to all *_parse* functions. Fixed
2578 many memory leaks as well.
2580 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2581 so that buffer overflows would not happen. All code now also
2582 checks the return value as it can fail.
2584 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Added reconnection support to server if the normal server looses
2587 its connection to the router (for example if router is rebooted).
2588 The server performs normal reconnection strategy implemented
2589 to the server. Affected file silcd/server.c.
2591 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Added new packet type SILC_PACKET_SET_MODE that is used to
2594 distribute the information about changed modes (for clients,
2595 channels and clients channel modes) to all routers in the
2596 network. Updated the protocol specification accordingly.
2598 Added functions into silcd/packet_send.c and
2599 silcd/packet_receive.c: silc_server_send_set_mode,
2600 silc_server_set_mode.
2602 Added new files silcmode.[ch] into lib/silccore that implements
2603 the encoding and decoding of Set Mode Payload. Added new type
2604 SilcSetModePayload. Moved the definitions of different modes
2605 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2607 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2609 * Oops, a little mistake in server's connection authentication
2610 protocol. The protocol is not ended with FAILURE but with
2611 SUCCESS if the authentication is Ok. :) Affected file is
2614 * Implemented NICK_CHANGE notify handling in server in the file
2615 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2616 the local clients on the channel. After the changing nickname
2617 in router environment snhould work and the [<unknown>] nickname
2618 should appear no more.
2620 The silc_server_replace_id function that receives the Replace ID
2621 payload now sends the NICK_CHANGE notify type also in the file
2622 silcd/packet_receive.c
2624 * Changed WHOIS and IDENTIFY command to support the maximum amount
2625 of arguments defined in protocol specs (3328 arguments). This
2626 fixed a bug that caused problems when there were more than three
2629 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Added extra parameter, command identifier, to the
2632 silc_client_send_command so that explicit command identifier
2635 Changed that ID list routines uses specific command identifier
2636 when sending WHOIS/IDENTIFY requests to the server so that they
2637 can be identified when the reply comes back.
2639 Affected files lib/silcclient/command.[ch],
2640 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2642 * Added `sender' argument to silc_server_packet_send_to_channel
2643 to indicaet the sender who originally sent the packet to us
2644 that we are now re-sending. Ignored if NULL. Affected file
2645 silcd/packet_send.[ch].
2647 * Added some server statistics support in silcd/server_internal.h
2648 SilcServerStatistics structure and around the server code. Also
2649 send some nice statistics information when client is connecting
2652 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2654 * Fixed channel ID decoding in server's JOIN command reply in
2655 silcd/command_reply.c
2657 * Fixed braodcasting of replace ID payload to not to send it if
2658 we are standalone server in silcd/packet_receive.c.
2660 * Fixed all channel message sending routines to not to send
2661 packets to clients that has router set, since they are routed
2662 separately in the same function earlier. Affects file
2663 silcd/packet_send.c and all channel packet sending functions.
2665 * In USERS reply, res_argv[i] are not allocated, the table
2666 is allocated. Thus changed that free the table, not its
2669 * In server's whois_check and identify_check if the client is
2670 locally connected do not send any WHOIS commands - they are not
2673 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2675 * Fixed some minor bugs in client when sending WHOIS command. The
2676 arguments was in wrong order.
2678 * Removed statis function add_to_channel from server in
2679 silcd/command.c that was previously used with the joining but
2682 * Tested USERS command in router environment successfully with two
2683 routers, two servers and two clients.
2685 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2687 * Reorganized the USERS command and command reply in client library
2688 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2689 When the command is given by user we register a pending command
2690 callback that will reprocess the command after the reply has been
2691 received from the server. When reprocessing the packet we then
2692 display the information. Thus, the USERS information is displayed
2693 now in the command callback instead of in the command reply
2694 callback. The processing of the command is same as previously
2695 when server has sent the command reply in the JOINing process.
2697 * Added to USERS command in silcd/command_reply.c to join the client,
2698 we didn't use to know about, to the channel after we've created
2699 a client entry for it. Also, for clienet we did know already still
2700 check whether it is on the channel or not and add it if not.
2702 * Removed silc_server_command_join_notify as the function and its
2705 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2707 * Changed the client's pending command handling to the same as the
2708 server's pending command handling. It is also now possible to
2709 execute command reply functions from other command reply
2710 function as the function callbacks for commands and command
2711 replies are one and same. The pending commands are not static
2712 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2713 in client connection context. Thus, pending commands are server
2714 connection specific as it is convenient.
2716 Changed the function silc_client_command_pending and
2717 silc_client_command_pending_del and added new function
2718 silc_client_command_pending_check. Removed the
2719 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2722 * Added cmd_ident, current command identifier, to the client
2723 connection context in lib/silcclient/client.h to keep track on
2724 command identifiers used in command sending. Client's command reply
2725 function handling now supports the mandatory command identifiers.
2727 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2728 funtions in client to fully support pending command callbacks.
2730 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2731 as one of the arguments to the application in the command reply
2734 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2735 before first releasing SILC but came back. Now it is removed again
2736 and should come back nomore. The FORWARDED flag was used only
2737 by the JOINing procedure by forwarding the command packet to router.
2738 Now, the JOINing procedure has been changed to more generic (due
2739 to various router environment issues) and FORWARDED is not needed
2740 anymore for anything. The protocol specification is yet to be
2743 Now, removed silc_server_packet_forward from server and the flag
2744 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2746 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2748 * Renamed NAMES command to USERS command. The NAMES was named that
2749 due to historical reasons. Now it is renamed. Also, rewrote
2750 parts of the USERS command. The nickname list is not sent anymore
2751 by the server. Only Client ID and mode lists are sent in the USERS
2752 command. Changed this also to the protocol specification.
2754 The client now resolves the names and stuff after it receives
2755 the USERS list from the server when joining to the channel.
2757 * WHOIS and IDENTIFY commands has been changed to support multiple
2758 Client ID's per command. One can now search for multiple users
2759 in the network by sending only one WHOIS or IDENTIFY command.
2760 Changed the code and the protocol specifications.
2762 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2763 uses silc_server_command_whois_parse to parse the request. */
2765 * If normal server, do not parse the WHOIS and IDENTIFY requests
2766 before sending it to the router. Saves some time.
2768 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * Fixed JOIN command on client library. Wrong number of arguments
2771 used to crash the client.
2773 * Added silc_server_channel_has_global function to check whether
2774 channel has global users or not.
2776 * Added silc_server_channel_has_local function to check whether channel
2777 has locally connected clients on the channel.
2779 * The silc_server_remove_from_one_channel now checks whether the
2780 channel has global users or not after given client was removed from
2781 the channel. It also checks whether the channel has local clients
2782 on the channel anymore. If it does not have then the channel entry
2783 is removed as it is not needed anymore.
2785 * The silc_server_notify now checks on JOIN notify whether the joining
2786 client is one of locally connected or global. If it is global then
2787 the channel has now global users on the channel and that is marked
2788 to the channel entry. Also, it now saves the global client to
2789 global list who is joining and JOINs it to the channel. This is
2790 for normal server, that is.
2792 Changed silc_server_send_notify_on_channel,
2793 silc_server_packet_relay_to_channel and
2794 silc_server_packet_send_to_channel check if we are normal server
2795 and client has router set (ie. global client) do not send the
2796 message to that client, as it is already routed to our router.
2798 * Implemented LEAVE notify type handling in silc_server_notify
2801 * Tested LEAVE command in router environment successfully. Tested
2802 with two routers, two servers and two clients.
2806 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2808 * Implemented SIGNOFF notify type handling in silc_server_notify
2811 * silc_server_remove_id now removes the client entry from all channels
2812 it has joined and thusly sends SIGNOFF notify type.
2814 * Rewrote the NAMES list generation in server by removing two excess
2815 loops. The lists are created now inside one loop.
2817 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2819 * silc_server_remove_channel_user checks now also global list
2820 for channel and client.
2822 * silc_server_new_channel_user checks now both local and global
2823 list for channel and client. Fixed a bug in client id decoding.
2824 Used to decode wrong buffer.
2826 * silc_server_channel_message checks now both local and global
2827 list for channel entry.
2829 * Tested channel joining (hence JOIN) in router environment
2830 successfully. Tested with two routers, two servers and two
2833 * Tested channel message sending in router environment successfully.
2835 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2837 * Added silc_server_save_channel_key into server.[ch] to save the
2838 received channel key in Channel Key payload processing. It is
2839 also used in JOIN command reply handling.
2841 Equivalent function silc_client_save_channel_key added into
2842 client.[ch] into client library.
2844 * Changed JOIN command reply to send information whether the channel
2845 was created or not (is existing already) and the channel key
2846 payload. Changed protocol specs accordingly.
2848 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2849 the request was sent by ID and not by nickname. Crashed on
2852 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2855 now correctly save the received data.
2857 * silc_server_free_sock_user_data now notifies routers in the
2858 network about entities leaving the network.
2860 At the same time implemented functions silc_server_remove_id
2861 and silc_server_send_remove_id to receive and send REMOVE_ID
2862 packets. The packet is used to notify routers in the network
2863 about leaving entities. The ID removed will become invalid in
2866 * Added function silc_idlist_del_server into server. Removes and
2867 free's server entry from ID list.
2869 * silc_server_private_message function now checks, if we are router,
2870 that the destination ID really is valid ID, naturally.
2872 * In router when NEW_ID packet is received (for new client) the
2873 hash of the Client ID is saved in the ID Cache but the
2874 client->nickname is set to NULL, instead of putting the hash
2877 IDENTIFY command now also checks that client->nickname must be
2878 valid. If it is not if will request the data from the server who
2879 owns the client. Added new function
2880 silc_server_command_identify_check.
2882 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2883 to set the command to already allocated Command Payload.
2885 * Tested private message sending in router environment with two
2886 routers, two servers and two clients. Fixed minor bugs and now
2889 * Fixed segfault from client's NAMES command. Used to crash if
2892 * Forwarded packets must not be routed even if it is not destined
2893 to the receiver. Changed server code comply with this.
2895 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2897 * Added `require_reverse_mapping' boolean value to ServerParams
2898 structure. If TRUE (not default) the server will require that
2899 the connecting host has fully qualified domain name.
2901 If the reverse mapping is not required and hostname could not be
2902 found the IP address is used as hostname.
2904 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2906 * Implemented version string checking to both client and server.
2907 The check is incomplete currently due to the abnormal version
2908 strings used in development version of SILC.
2910 * Changed all command functions in server to use the new
2913 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2915 * Changed char *data to unsigned char *data in ID Cache system to
2916 support binary data as ID Cache data. Changed code to support
2917 binary data in lib/silccore/idcache.c.
2919 * Renamed silc_server_packet_relay_command_reply to
2920 silc_server_command_reply as it is normal packet receiving
2921 function. Rewrote the function to accept command replys for
2922 servers and not only for clients.
2924 * Mark remote router always as registered server if we are connecting
2925 to it. Otherwise, commands sent by the router to us are ignored.
2927 * All ID List find routines now returns the ID Cache Entry pointer
2928 as well if requested.
2930 * WHOIS command works now in router environment, tested with two
2931 routers, two servers and two clients.
2933 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2934 in router environment (as it is almost equivalent to WHOIS) but
2935 hasn't been tested thoroughly. Added new functions:
2937 silc_server_command_identify_parse
2938 silc_server_command_identify_send_reply
2939 silc_server_command_identify_from_client
2940 silc_server_command_identify_from_server
2942 * Disabled route cache adding because adding two different ID's with
2943 same IP replaces the old cache entry thus giving wrong route.
2944 The entry->router->connection is always the fastest route anyway
2945 so route cache may not be needed. Of course, new routes maybe
2946 established after receiving the ID when the entry->router->connection
2947 might not be anymore the most optimal.
2949 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Add route cache for received ID for fast routing.
2953 * Added silc_server_packet_route to route received packet on router
2954 that is not destined to us.
2956 * Renamed silc_server_get_route to silc_server_route_get.
2958 * Added id_string and id_string_len fields into SilcServer to
2959 include encoded ServerID for fast comparing without excess
2960 encoding of the ID's.
2962 * Cleaned up WHOIS command on server side. Added following static
2965 silc_server_command_whois_parse
2966 silc_server_command_whois_check
2967 silc_server_command_whois_send_reply
2968 silc_server_command_whois_from_client
2969 silc_server_command_whois_from_server
2971 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2972 arguments in command replies. All command functions should be
2973 updated to use this macro.
2975 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Minor typo fixes on command reply handling on server.
2979 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2981 * Added silc_server_command_add_to_channel internal routine to add
2982 the client to the channel after router has created the channel and
2983 sent command reply to the server.
2985 * Added generic silc_server_send_command to send any command from
2988 * Use static buffer with ID rendering instead of duplicating data.
2990 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Fixed a channel user mode bug when joining to a channel server gave
2993 everybody channel founder rights, oops.
2995 * We mark ourselves as the router of the incoming server connection
2996 if we are router ourselves. This way we can check in some packet
2997 sending functions whether it is locally connected server. For
2998 incoming router connections we put NULL.
3000 * For router sending packets locally means now always sending the
3001 packet cell wide; to local clients and local servers. For normal
3002 server sending packet locally means sending it to only local
3005 * Fixed the JOIN command to really work in router environment. If the
3006 channel is created it is always created by the router. Router is
3007 also responsible of making the initial joining to the channel,
3008 sending JOIN notify to the sending server and distributing
3009 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3010 does not exist server doesn't do anything else but forward the
3011 command to the router which performs everything.
3013 * Added silc_server_send_channel_key function to send the Channel Key
3016 * Added silc_server_create_channel_key to create new channel key. The
3017 channel key is now re-generated everytime someone joins or leaves
3018 a channel, as protocol dictates. Note: channel->key_len is the
3021 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3023 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3024 packet_receive.[ch] to separate packet sending and receiving
3025 routines. The server.[ch] now includes everything else including
3026 actual packet processing (writing and reading data) and other
3029 Renamed silc_server_private_message_send_internal to
3030 silc_server_send_private_message. The routine is still though
3031 used only to relay private messages as server does not send
3032 private messages itself.
3034 Renamed silc_server_new_channel to silc_server_create_new_channel
3035 and added new function sicl_server_new_channel that handles the
3036 incoming New Channel packet. Added also new sending function
3037 silc_server_send_new_channel to send New Channel Payload.
3039 * Added new function silc_server_notify to process incoming notify
3040 packet to the server/router. Server may then relay the notify
3041 to clients if needed.
3043 * Added new function silc_server_new_channel_user to process incoming
3044 New Channel User packet. Router will redistribute the packet and
3045 send JOIN notify to its local clients and locally connected servers
3046 if needed. Normal server will send JOIN notify to its local client
3047 on same channel when received this packet. Added also corresponding
3048 sending function silc_server_send_new_channel_user to sent the
3051 * Added boolean route argument to send_notif_to_channel and
3052 packet_send_to_channel functions to attempt to route the packet
3053 if it is TRUE and send only locally if it is FALSE.
3055 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * silc_server_replace_id now broadcasts the received replace ID
3058 packet if it is not broadcast packet already. The router must
3059 broadcast to inform other routers about changed ID.
3061 * Added backpointer to server's router into SilcServer context in
3062 silcd/server_internal.h.
3064 * Fixed silc_server_packet_broadcast to send correct broadcast
3067 * The channel key is now distributed to the local client as soon
3068 as it is received from the router (in router environment) so that
3069 no other packet may be sent for the channel until client has
3072 * silc_server_remove_channel_user now broadcasts the received
3073 Remove Channel User packet if it is not broadcast packet already.
3074 The router must broadcast to inform other routers about removed
3077 * Added users field into SilcPacketContext that is a reference count
3078 of the context. One can increase the reference count by calling
3079 silc_packet_context_dup which is now changed to just increase the
3080 reference count instead of duplicating the data. The reference
3081 count is decresed by calling silc_packet_context_free that will
3082 free the data after the reference count hits zero.
3084 For now on the packet context and everything allocated into it
3085 (including the raw packet from network) must be freed by calling
3086 the new silc_packet_context_free function. Added also new function
3087 silc_packet_context_alloc that must be used now to allocate the
3088 context. This also means that if a routine is asynchronous from
3089 silc_[client/server]_packet_parse_type the packet context must
3090 be duplicated by calling silc_packet_context_dup. Otherwise it
3091 gets free'd after silc_[client/server]_packet_parse_type returns.
3092 Also, one must remember that if packet is duplicated then its
3093 reference count must be decresed by calling the free function as
3094 many times as it was duplicated.
3096 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3097 from both client and server.
3099 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3101 * Made joining to a channel working in router environment.
3103 * Cleaned up JOIN command on server side and create function
3104 silc_server_command_join_channel internal routine to make the
3107 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3109 * Changed silc_command_pending list to SilcDList. Also, added
3110 `ident' field to SilcServerCommandPending structure to identify
3111 the reply and to call correct callback.
3113 Added silc_server_command_pending_check function to replace the
3114 corresnponding macro. The silc_command_pending list is not
3117 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3118 to set identifier to previously allocated Command Payload. It
3119 is used to set identifier for command when resending Command
3122 * Added silc_command_payload_encode_payload to encode Command
3123 Payload buffer from SilcCommandPayload structure.
3125 * Added silc_argument_payload_encode_payload to encode Argument
3126 payload buffer from SilcArgumentPayload structure.
3128 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3130 * Changed WHOIS command to support router connection on server side.
3131 The whois request is always sent to router unless the server is
3132 standalone server. After server has received the reply from the
3133 router will it send the reply to the client.
3135 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3136 broadcast received broadcast packet. The function is used only
3137 by router. The broadcast packet is always sent to the router's
3140 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3141 render given ID to printable string, for log files for example.
3143 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Made basic router to router connections working. At least they
3146 can now connect to each other but nothing really works the way
3147 they are supposed - yet.
3149 * Added new initiator token to RouterConnection configuration
3150 file in silcd/serverconfig.[ch]. It is used to tell whether we
3151 are the initiator to the remote router or whether we'll expect
3152 the other end to connect.
3154 * Moved registering of listener task to silc_server_init, hence
3155 the server starts listenning as soon as it is run, even if it
3156 does not have connections to other routers. Let's see how well
3159 * Changed default connection retry timeouts for more suitable in
3162 * Removed cipher and such arguments from silc_idlist_add_client
3163 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3164 Added new function silc_idlist_add_data to add the keys and stuff
3167 * Added SilcIDListData structure and added it to SilcClientEntry
3168 and SilcServerEntry as their first field in the structure. This
3169 way we can explicitly cast the ID entries to the SilcIDListData
3170 structure and get common data for the entries. In past, we had
3171 to first check what type of connection it is and then cast it to
3172 correct ID entry type. Now, we can directly cast the opaque
3173 pointer to the SilcIDListData (no matter what ID entry it actually
3174 is) and get the data needed.
3176 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3178 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3179 in some circumstances even if threre were timeout tasks, though not
3180 IO tasks, but tasks anyway. Now fixed.
3182 * Defined SilcServerConnection structure to hold connection specific
3183 stuff about directly connected servers and routers. The definition
3184 is currently in silcd/server_internal.h. I thought about having
3185 a bit more important role fro this struct but for now it is used
3186 only when connecting to other server (or router actually).
3188 * Added connecting retry support in server when connecting to
3189 router(s). The retry feature implement exponential backoff
3190 algorithm. Also, added SilcServerParams structure to hold default
3191 parameters for server. For now, it include these retry settings
3192 and are hard coded. After server is moded to be as Silc Server
3193 Library this structure will be more important.
3195 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * Changed client librarys channel->clients table to SilcList and
3198 changed code accordingly.
3200 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3202 * Changed client's channel table to SilcList and changed code
3203 accordingly. Also changed SilcChannelClientEntry to include back-
3204 pointer to the channel so that client entry can use that structure
3205 as list as well and we have fast cross-reference to the channel.
3206 This change dramatically decreased the complexity of channel
3207 handling with client entry and vice versa (removed one extra
3208 loop when searching for channel entry from many functions).
3210 * Changed server->sim from table to SilcDList and changed code
3213 * NAMES command can now be used from user interface. It will show
3214 the user list on the channel, neatly.
3216 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3217 Code now saves realname of the user if it becomes available.
3219 * Renamed configure.in to configure.in.pre and made ./prepare
3220 script to automatically add correct version string to
3221 configure.in which it creates from configure.in.pre.
3223 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3225 * NAMES command reply now shows users mode with the nickname when
3228 * Moved silc_client_ch[u]mode[_char] functions from
3229 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3230 place sucks, they are utility functions and should be in some
3233 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3235 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3238 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Added TRQ (efficient deque and list library) into lib/trq. This is
3243 a very good list library that is currently used in the SILC. Defined
3244 SilcList API over the library because I didn't like the API very
3245 much. See lib/trq/silclist.h for the API and examples of how to
3246 use the API. Fixed various places in the code to use the new
3247 SilcList API. The SilcList is meant for lists that has a structure
3248 already defined as a list. It is not suitable to add just some
3249 context to the list (in TRQ, the context is the list actually).
3251 So, I defined SilcDList that can be used for the purpose where
3252 predefined list structure does not exit. This can be used as
3253 such list. Now some context just can be added to the SilcDList.
3254 Currently this list is not used in the SILC just yet, though there
3255 are a lot places where this can replace dynamically allocated
3256 tables and I will fix these places, later, to use SilcDList.
3257 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3258 and use TRQ internally).
3260 Also fixed some annoying warning messages that the original TRQ
3261 code generated. Also minor changes to TRQ's Makefile.in.
3263 * Added support for querying by Client ID to both WHOIS and
3264 IDENTIFY commands into server, as required by the protocol.
3266 * Removed method function pointers from SilcBuffer structure. They
3267 weren't used to anything and just increased the context size for
3268 no good reason. This change also made silc_buffer_alloc and
3269 silc_buffer_free functions inline functions.
3271 * Disabled command flooding detection support until it's fixed so
3272 that it accepts commands in but does not execute them more than once
3275 * Added silc_net_localhost(), to return local hostname, into
3276 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3277 that must be initialized before calling silc_client_init.
3279 * Added new function: silc_server_send_notify_on_channels to send
3280 notify messages to all channels client has joined. It is assured
3281 that the message is sent only once per client.
3283 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3284 lib/silcutil/silcutil.[ch] as silc_format function. The new
3285 function is generic and is used by server as well, not only by
3286 the logging routines.
3288 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3289 the provided version string was not acceptable. Added new function:
3290 silc_ske_check_version into lib/silcske/silcske.h. The function
3291 must be implemented by the application (client or server) and it
3292 does not reside in the SKE library. The function checks the version
3293 string remote end sent.
3295 * Added back pointers (to opaque context and to SilcSocketConnection)
3296 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3298 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3299 duplicate packet context structure.
3301 * Changed `notify' client operation to send same arguments as client
3302 receives from server except for ID's. ID's are mapped to correct
3303 ID entry and that is returned. Also, if channel entry is not sent
3304 by server but the notify is for channel the channel entry is sent
3305 to application (otherwise application doesn't know that it is for
3306 channel (library gets it from packet's Destination ID)).
3308 * Added silc_client_remove_from_channels into client library to
3309 remove a client from all channels it has joined to. Used when
3310 received SIGNOFF notify from server. Added also new function
3311 silc_client_replace_from_channels to replace old ID entry with
3312 new ID entry on all channels. Used when received NICK_CHANGE
3315 * Fixed ID Cache list handling in silc_idlist_get_client in
3316 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3317 to get (or query) client by ID.
3319 * Updated TODO list.
3321 * Added connection authentication status message defined by the
3322 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3323 support for these into the code in client and server side.
3325 * Added generic function silc_client_send_command to send any command
3326 with variable argument list. Application should use this function
3327 to send commands if the command functions provided by the library
3328 does not suite for the application's user interface needs.
3330 * Added new `failure' client operation. Application is notified about
3331 received failure packet if client is executing a protocol. In this
3332 case the protocol's execution has failed.
3334 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3335 is required by the protocol.
3337 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3338 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3341 * Added status flag to SilcSKE object to indicate realtime status
3342 of the SKE protocol.
3344 * Application receives now exactly same command reply arguments as
3345 the library receives from server. However, if ID is received the
3346 corresponding ID entry is returned to the application (eg. Client
3347 ID is mapped to correct SilcClientEntry entry and that is returned).
3348 Changed command_reply client operation due to this change.
3350 * Changed all ID's in commands and in command replys as ID Payloads.
3351 Change affected both client and server side codes.
3353 All ID's sent in SILC network (with execption of ID's in SILC
3354 Packet header) are sent in ID Payload to support variable length
3357 * Server now notifies nick changes and notifies all clients on
3358 the channels about the new nickname (about the new Client ID,
3361 * Implemented CMODE command to change channel modes. Supports all
3362 channel modes defined by the protocol specs except ban and invite
3363 lists. (Also, private channel key mode is supported but support for
3364 setting private channel key in client is missing, thus, this mode
3365 has no effect on client side (except that server requires that the
3366 client uses private channel key and normal channel traffic does not
3369 Also, invite mode works per se, but INVITE command does not work
3370 yet correctly, so you can set channel as invite only channel but
3371 inviting clients to the channel does not work (it is yet to be
3372 thought what's the best way to do it).
3374 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3375 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3376 Implemented CUMODE command to change user's mode on the channel.
3377 Supports all modes defined by the protocol specs.
3379 * Added NAMES command reply to return users modes on the channel.
3381 * Removed unnecessary and slow ciphers from lib/silccrypt.
3383 * Set SO_KEEPALIVE option to connection sockets by default.
3385 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3387 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3388 redefined the Notify Payload into protocol specs.
3390 * Added silc_id_payload_parse_id to get ID directly from raw
3393 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3396 accept searching by Client ID as well.
3398 * Added support for LEAVE and SIGNOFF notify types in client library.
3400 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3401 to parse ID Payload from raw data.
3403 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Added flags parameter into silc_ske_assemble_security_properties
3406 function in lib/silcske/silcske.[ch].
3408 * Changed notify client operation to fit better for notify messages
3409 sent by server. The notify payload received from server is now
3410 passed to the application (after parsing it to SilcNotifyPayload).
3411 It is application's responsibility to retrieve the arguments
3412 from the payload and show the message the way it wants. The message
3413 sent by server is implementation specific.
3415 * Changed public keys to comply with the protocol specification.
3416 Old public keys are not supported anymore and are not compatible.
3418 * Removed nickname from Channel Payload as the latest draft removed
3419 it. The client must resolve the nickname from the NAMES command
3420 reply received when it joined the channel.
3422 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3424 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Fixed some errors in protocol specification drafts.
3428 * Created lib/silccore/silcnotify.c to implement Notify Payload
3429 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3430 generic payloads described by protocol specifications. The file
3431 includes implementations for ID Payload and Argument Payload.
3433 * Changed Command Payload implementation to use the new Argument
3434 Payload. Changed command_xxxx_payload to command_payload_xxxx
3435 to comply with SILC coding conventions.
3437 * Added suppport for Argument Payload handling in Notify Payload
3438 implementation as protocol requires it. Added the new support
3439 into server and client lib as well.
3441 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Added support for multiple nicknames on same channel. [n] is
3444 added locally to the nickname if there are more than one same
3445 nicknames on the channel.
3447 * Server now sends all nicknames that matched WHOIS request.
3448 Client also shows the list received from server.
3450 * Added TOPIC command to client side. User can now set and show
3451 current topic on channel.
3453 * Added MOTD command to client and server. Also, server sends the
3454 motd when client connects to the server.
3456 * Changed version strings to comply ISO 8601.
3458 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Fixed protocol error handling in client library. It should now
3461 cope even if the SKE fails for some reason.
3463 * Made new protocol specification drafts for submitting to IETF.
3465 * Implemented TOPIC command to server in silcd/command.c.
3467 * Added two new notify types into lib/silccore/silcnotify.h:
3468 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3469 notify nickname change and topic setting/change on a channel.
3471 * API change of command_reply operation in client library. The
3472 application gets now the status type received from server as well.
3474 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3478 * Cras fixed and optimized the packet handling even further and
3479 it should work now. Minor change to the prototype of function
3480 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3482 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Added new function into lib/silcutil/silcschedule.[ch]:
3485 silc_schedule_with_fd to select() a specified fd. The function
3486 returns after timeout expires or data arrives or goes. The
3487 function is used by packet routines to wait that all data is
3488 received from network.
3490 * Fixed data reading from network in lib/silccore/silcpacket.c.
3491 The code now assures that all data is read from the fd and then
3492 continues packet processing. This was a bug fix since the code
3493 used to drop some data in some circumstances.
3495 * Added new function into lib/silcclient/client.[ch]:
3496 silc_client_start_key_exchange to start key exchange after
3497 connection has been established to server. The code internally
3498 now uses this funtion but its main purpose was to provide it
3499 for applications that perform their own connecting. After
3500 application has created a connection it merely calls this
3501 function to start the key exchange between client and server.
3502 The library takes care of everything else after that.
3504 Updated also lib/silcclient/README to explain the usage of
3507 * Do not send to application information that connection has
3508 been established. Application gets notified it by connect
3511 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Applied cras's patch to add silc_schedule_one function. The
3514 function runs scheduler once and returns.
3516 * Fixed the scheduler after cras messed it up. The timeout
3517 handling works now as it's supposed to work.
3519 * Added into lib/silccore/ silcnotify.h to include notify
3520 message types support. Changed silc_server_send_notify*
3521 functions, in server.[ch], to support those new notify types.
3522 Added the support for the notify types into client library,
3523 as well. Added new notify client operation into ops.h in
3526 * Changed silc_server_packet_send_to_channel to send normal
3527 packets instead of just channel message packets. The function
3528 is now used to send the notify packets to channels. It is not
3529 used to send channel message packets anymore, as server never
3532 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3533 va_arg()s as it seems to require it nowadays. I guess, if SILC
3534 is compiled with older va_arg() the new code should work anyway.
3536 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3538 * Splitted core library. Core library (lib/silccore) includes
3539 now only SILC protocol specific core (and common) components.
3540 Created new utility library (lib/silcutil) that includes more
3541 generic purpose stuff. The stuff for util library was taken
3542 from the old core library. This was minor and easy split.
3544 * Created SILC Client Library (lib/silcclient) that includes
3545 implementation of the SILC client without user interface. This
3546 was major move from silc/ directory. The code has been changed
3547 so that it is transparent towards the user interface. The
3548 silc/ directory includes now the same user interface as before
3549 and it uses the new client library. Read lib/silcclient/README.
3550 Basicly, the client library performs everything else related
3551 to SILC except user interface handling. Also, configuration
3552 files are considered to be part of user interface and library
3553 does not handle them.
3555 This change also changed a lot of structures, function naming etc.
3556 Most important change was that SilcClientWindow object was
3557 renamed to SilcClientConnection in the client library. Created
3558 also new file lib/silcclient/ops.h. Also added new files
3559 silc/local_command.[ch] and silc/client_ops.[ch].
3561 All these changes were made to make it easier for user interface
3562 designers to create what ever user interface for the SILC client
3565 It is also expected that the server will be moved to lib
3566 directory as well and SILC Server Library will be created;
3567 sometimes in the future.
3569 * Removed Local commands from lib/silccore/silccommand.h as
3570 they are application specific and new client library does not
3571 handle any of those anymore.
3573 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3574 old client implementation in silc/.
3576 * Added support for callback functions in SILC_LOG_* macros.
3577 Application can now set its own callbacks that will be called
3578 instead of using the default functions that will always print
3579 the debug messages to stderr (or stdout). Also, debugging can
3580 now be disabled by setting silc_debug to FALSE and re-enabled by
3581 setting it to TRUE. Note, that logging will still work even
3582 if debugging is disabled.
3584 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3585 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3586 silc_log_reset_debug_callbacks.
3588 * To enable debugging in silc client one must give now -d
3589 option on command line.
3591 * Changed silc_schedule_init to automatically allocate task queues
3592 if they are not allocated before calling it.
3594 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3596 * Added GMP 3.1 into math library.
3598 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3601 a channel in SILC network. The packet is used by servers and
3602 routers to notify other routers that user has left a channel.
3603 This little feature was missing until now. Added the feature
3604 to protocol specification as well.
3606 Added functions: silc_server_send_remove_channel_user and
3607 silc_server_remove_channel_user into server.[ch].
3609 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3610 lib/silccore/silcpacket.h. However, they are not implemented
3613 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3615 * Fixed joining to a channel and sending channel messages
3616 between server and router. The channel message sending should
3617 now work inside a cell.
3619 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Fixed the private message sending between server and router.
3622 The private message sending should now work inside a cell.
3624 * Added silc_server_replace_id into server.[ch] to replace
3625 existing ID in the SILC network.
3627 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3628 and silc_idlist_replace_server_id into idlist.[ch] in server.
3630 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3632 * Fixed the server to server connections. Server can again now
3633 connect to router. Router to router connections probably does
3636 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Added dynamic protocol registering support. Now protocols can
3639 registered and unregistered on the fly. Patch by cras.
3641 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3643 * Added lib/contrib directory to hold routines that some platforms
3644 don't have but are needed by SILC.
3646 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3647 into lin/contrib to provide getopt() and getopt_long() for
3648 those who don't have it.
3650 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Added AWAY command to client. When away message is set and
3653 client receives a private message packet the client automatically
3654 replies to the sender with the away message.
3656 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3657 bug seemed to be the cause of recent problems when compiling
3660 * Added version detection support to SKE protocol specification
3661 and added the new changes to the SKE implementation as well.
3662 There were other minor changes in the SKE protocol as well.
3664 Many changes in lib/silcske/silcske.[ch] and in
3665 lib/silcske/payload.[ch].
3667 * Added ^U functionality, clear input line. Patch from cras.
3669 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3671 * Mainly small bugfixes on core library. Fixed some debugging
3672 logging and buffer overflow in silclog.c.
3674 * Updated config.sub and config.guess on the distribution tree.
3676 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Added command lagging support in server. Client may execute
3679 commands now only once in two seconds.
3681 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Optimized packet reception. MAC computation and checking is now
3684 also more optimized. A lot previously duplicated code is now
3685 used as generic by both client and server.
3687 * Fixed key pair generation in clientutil.c
3689 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Added into lib/silccore/silcbufutil.[ch] new function;
3692 silc_buffer_realloc.
3694 * Moved generic packet sending/encryption functions to
3695 lib/silccore/silcpacket.[ch] from client and server. Some
3696 rewriting of the functions.
3698 * Moved all generic packet reception/decryption functions to
3699 lib/silccore/silcpacket.[ch] from client and server. The
3700 packet processing is now much cleaner in both client and server.
3701 These were major changes in both client and server.
3703 * Created many common functions in server to do packet sending.
3704 Previously code were duplicated a lot, this has been removed
3707 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * Rewrote major parts of the ID cache system. Don't know
3710 whether it is better now or not but at least the API is more
3713 * Major rewrite on ID cache stuff on client because of the ID
3714 cache API changes. Added idlist.c to client.
3716 * Also major rewrite on ID cache stuff on server as well.
3717 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3718 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3719 in hand, instead they are all put into the ID cache system now.
3720 All server_idlist_* routines uses ID cache now instead of
3721 traversing its own lists (those lists does not exist anymore).
3722 SilcIDList though still exists. Also, SilcXXXEntry's are
3725 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Finally made the SKE implementation compliant to the protocol
3728 specification. All mp integers are now binary encoded as
3729 opposed being HEX encoded.
3731 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3734 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3735 functions: silc_[encode/decode]_pem. Also added function
3736 silc_encode_pem_file to PEM encode with newlines ('\n') for
3739 * SILC public keys are now encoded either PEM or binary. Same
3740 option is for private keys as well. By default private keys
3741 are binary encoded and public keys PEM encoded. Silly HEX
3742 encoding were removed.
3744 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3745 function to create fingerprints.
3747 * Fixed a bug in SHA1; does not change the original data anymore.
3749 * Partly implemented INFO command on client and server side.
3750 Fixed CLEAR command. Changes to SERVER command; show current
3751 server(s) when giving command without arguments. Added
3752 VERSION command to client.
3754 * Added check to server that unregistered connections cannot
3755 execute commands (unless it is specificly allowed).
3757 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3759 * Fixed screen refresh.
3761 * Fixed channel joining bug from client. On some circumstances
3762 client tried to join to a channel it had already joined.
3764 * Added public key verification process into client's protocol.c.
3765 The client now verifies the public key from user and saves
3766 it into ~./silc/serverkeys/ directory.
3768 Added into: clientutil.[ch]: silc_client_verify_server_key.
3770 * Changed SKE protocol's silc_ske_initiator_finish function
3771 to accept callback function that verifies the received public
3772 key. Removed old silc_ske_verify_public_key function.
3774 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3777 silc_pkcs_private_key[_data]_set.
3779 * Made the password and public authentication more cleaner in
3780 server's protocol.c.
3782 * Removed historic and obsolete protocol `channel_auth' from
3783 both client and server.
3785 * Removed wrong way of sending command status messages from
3786 server to client in server's command.c. The old way violated
3787 protocol specification.
3789 Changes to silccore/silccommand.[ch]: removed
3790 silc_command_encode_status_payload -> not needed anymore,
3791 changed silc_command_encode_payload_va to accept extra
3792 argument on variable argument list. The argument type must
3793 now be provided to the function. Also, added new function:
3794 silc_command_encode_reply_payload_va which is same as
3795 normal command_encode_payload_va except command status type
3796 is provided as extra argument.
3798 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * Added ~./silc directory handling. The directory includes the
3801 public and private keys for the client.
3803 Added silc_client_check_silc_dir, silc_client_create_identifier
3804 and silc_client_load_keys.
3806 * Implemented SILC protocol compliant public key. Added public
3807 and private key saving to and loading from files.
3809 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3810 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3811 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3812 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3813 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3815 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3816 silc_pkcs_load_[public/private]_key.
3818 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Added silc_server_get_route (route.[ch]) to get connection
3821 data for the fastest route for given ID.
3823 * Implemented INVITE command on client and server. The command
3824 were re-defined in the SILC Protocol Specification and the
3825 implementation now complies with the specification.
3827 * Implemented PING command on client and server.
3829 * Implemented NAMES command on client and server. The server side
3830 supports currently only normal server not router server yet.
3831 Some changes to NAMES definition in SILC protocol specification.
3833 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3835 * Implemented LEAVE command on client and server.
3837 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3838 again. This change was made to the protocol as well. Server
3839 should not violate the protocol specification anymore.
3841 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3844 was tested. SOCKS4 was not but should work anyway.
