1 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added new distribution feature, DISTLABEL. Every distribution
4 can define own preprocessor label that can be used in the
5 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
6 file distributions, acconfig.h.pre and prepare.
8 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
10 * Added Makefile.defines_int to include the actual definitions
11 for Makefile.defines.in. Tested the new distribution system,
12 created distributions and tested installation.
14 * Added AWAY message printing to the Irssi SILC client. Added
15 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
17 * Added SCONNECT command to call the SILC's CONNECT command.
18 Cannot use CONNECT directly since Irssi uses that internally.
19 Affected file irssi/src/silc/core/silc-servers.c.
21 Added ACTION local command. It is same as ME command but takes
22 the channel as mandatory argument.
24 Rewrote some of the Irssi's help files to suite for SILC
27 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
29 * Added Makefile.defines[.in] that should for now on be included
30 in all Makefile.am file in the source tree. That file includes
31 all common compilation definitions for SILC source tree.
33 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
35 * Minor changes to the ./prepare script to change the package
36 name according the distribution name to the configure.in.
38 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
40 * Created new distribution system. Added file `distributions'
41 that defines all the distributions that can be created out of
42 the SILC source tree. The ./prepare script now reads that
43 file to determine how to prepare the distributions. The
44 first argument to the ./prepare is the name of the distribution
45 and second is the version of the distribution. If given
46 without arguments it creates the default (toolkit) distribution
47 with the default version (defined in ./prepare).
49 All Makefile.am files that are subject to the distributions
50 are now named as Makefile.am.pre. These are ./Makefile.am
51 and lib/Makefile.am. Others may be changed later.
53 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
55 * Added invite list, ban list, some key management and connection
56 error message printing to module formats in the Irssi SILC client.
58 * Added new silc_client_set_away_message to set the away message
59 that is back to the person who sent private message. The
60 affected file lib/silcclient/silcapi.h and the
61 lib/silcclient/client_prvmsg.c.
63 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
65 * Fixed the private message sending in the Irssi SILC client,
66 added local command KEY to the Irssi SILC client.
68 Added key management and key agreement message formats to the
69 irssi/src/fe-common/silc/module-formats.[ch].
71 Added USERS (alias WHO) printing, server/router operator
72 indication and LIST command printing to the module formats.
74 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
76 * Fixed channel joining notify handling, cumode notify handling
77 from Irssi SILC client.
79 * Added SILC specific module-formats to the Irssi SILC client so
80 that SILC specific message hilighting, colors etc is possible.
81 Affected file irssi/src/fe-common/silc/module-formats.[ch].
83 Added channel mode, channel user mode, actions, notices,
84 whois and whowas printing to the the module-formats.c.
86 * Fixed a bug in channel deletion in the server. The channel
87 is not left to the cache even if the channel founder auth mode
88 is set when there are no users anymore on the channel. Affected
91 * The silc_net_localhost now resolves the entire hostname including
92 the domain name. Affected file lib/silcutil/silcnet.c.
94 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
96 * Changed the ask_passphrase client operation to be ascynchronous.
97 It has now a completion callback and a context that the
98 application must call after it has got the passphrase from
99 the user. Affected files lib/silcclient/silcapi.h,
100 lib/silcclient/protocol.c, lib/silcclient/command.c and
103 Added SilcAskPassphrase callback that the application calls
104 to deliver the passphrase to the library.
106 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
107 The public key verification and especially a certificate
108 verification is asynchronous procedure.
110 Added new SILC_SKE_STATUS_PENDING status to indicate the
111 request is pending and a callback will be called to finalize
114 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
115 indicate that remote end did not send its public key (or
116 certificate), even though we require it. Added check for this
117 condition in the SKE. This was a security bug, now fixed.
119 Defined new SilcSKEVerifyCbCompletion callback that is called
120 when the verification process is completed.
122 The affected files lib/silcske/silcske_status.h and
123 lib/silcske/silcske.[ch].
125 * Changed the verify_public_key client operation to be async
126 as well. Defined SilcVerifyPublicKey callback that is used to
127 indicate the success of the public key verification process.
129 Changed the server and client to use the new async client
132 * Changed the Irssi SILC client's internal scheduler to be called
133 twice as many times as it used to be. As a result the client
134 should be a bit faster now. Affected file is
135 irssi/src/silc/core/silc-core.c.
137 * Added support to Irssi SILC client of asynchronous public key
138 verification and passphrase inquiry. Affected file is
139 irssi/src/silc/core/silc-core.c.
141 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
143 * Do not say "You have left channel %s" in client library.
144 Moved it to the application. Affected files are
145 lib/silcclient/command.c and silc/client_ops.c.
147 * Fixed silc_client_get_clients. Command context was not
148 duplicated and was freed memory in the callback. Affected
149 file lib/silcclient/idlist.c.
151 * Do not say "you are now talking..." on JOIN command in the
152 client library. The appliation must handle it.
154 * Do not say ".. changed topic to" in command reply in the
155 client libary. The application must handle it.
157 * Fixed TOPIC command sending in the client library.
159 * Fixed a memory leak in silc_client_command_free in the file
160 lib/silcclient/command.c.
162 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
164 * Imported a modified version of Irssi client to the source tree.
165 The Irssi will be used to create a new client called
166 Irssi SILC. Imported to irssi/.
168 Added silc_core_init_finish function to the Irssi. Affected
169 file irssi/configure.in.
171 A lot changes in the Makefile.ams around the irssi tree.
173 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
175 * Do not rehash if the new size is same as the old size of the
176 hash table, in the silc_hash_table_rehash*. The affected file
177 lib/silcutil/silchashtable.c.
179 * Replaced hash_table_del_by_context calls from the server
180 (when channel->user_list and client->channels) to the
181 hash_table_del as it is sufficient and faster.
183 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
185 * Added silc_hash_table_list, silc_hash_table_get and the
186 SilcHashTableList structure to provide an alternative way to
187 traverse the hash table. The affected files are
188 lib/silcutil/silchashtable.[ch].
190 * Changed the server's idlist routines to use the hash table
191 routines to optimize the code.
193 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
195 * Replaced the client entry's `channel' list and channel entry's
196 `user_list' list to hash tables for optimized lookup. Changed
197 the code to use the hash table interface around the code.
198 Affected file lib/silcd/idlist.[ch].
200 * Added `auto_rehash' boolean argument to the function
201 silc_hash_table_alloc to indicate whether the hash table should
202 auto-rehash when it thinks is appropriate time. It will
203 increase the hash table size if the there is twice as much
204 entries in the table than the size of the table, and will
205 decrease the size if there are twice as less entries than
206 the size of the table.
208 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
210 * Fixed silc_xxx_get_supported to not crash at some circumstances.
212 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
214 * silc_idcache_purge_by_context deletes the entry now by context
215 as it is supposed to do. Affected file lib/silccore/idcache.c.
217 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
218 client is not anymore valid (WHOWAS givens the info) and not
219 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
221 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
223 * Removed the `data' and `data_len' arguments from the ID Cache
224 interfaces and added `name' argument. ID Cache does not handle
225 anymore the binary data only a names associated with given ID.
227 * When hashing a Client ID with silc_hash_id the entire ID is
228 not hashed anymore, instead only the hash of the Client ID is
229 hashed. This way we can access the Client ID from the cache
230 with Client ID but with the hash of the ID (which is a hash of
231 the nickname) as well without any difference in performance.
233 Added also silc_idcache_find_by_id_one_ext to do one on one
234 searching when we have the actual ID. Added also function
235 silc_hash_client_id_compare. The affected files are
236 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
238 * When hashing the name associated with a ID it is always done
239 in lowercase. This way we can access the cache without worrying
240 about case-sensitivity, even though, for example nicknames are
243 * Fixed a bug in server with channel message sending. It put
244 wrong ID type as destination ID. The affected file
247 * silc_idcache_del_by_context now deletes from all hash tables
248 by context. Affected file lib/silccore/idcache.c.
250 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
252 * Changed the client library to use the new ID Cache interface.
253 Changes around the source tree.
255 * Added silc_hash_table_rehash_ext to rehash with specific
256 hash function. Affected file lib/silcutil/silchashtable.[ch].
258 * Added silc_hash_string_compare to compare two strings in the
259 hash table. Affected file lib/silcutil/silcutil.[ch].
261 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
263 * Added new function silc_idcache_del_by_context into the
264 lib/silccore/idcache.[ch].
266 * Changed the server's ID list routines to use the new ID Cache
267 interface. Changes around the source tree.
269 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
271 * Added silc_hash_table_del[_by_context]_ext functions in to the
272 lib/silcutil/silchashtable.[ch].
274 Removed silc_hash_table_find_all* routines and added new
275 silc_hash_table_find_foreach to replace them.
277 Added silc_hash_table_replace_ext function as extended
278 replacing function. Separated the simple hash table interface
279 from the extended hash table interface in the file
280 lib/silcutil/silchashtable.h.
282 * Fixed minor bugs and changed it to use some of the new
283 hash table functions in lib/silccore/idcache.c
285 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
287 * Added new function silc_hash_table_find_all to return all keys
288 in the hash table by the specified key. As the hash table is
289 collision resistant it also makes it possible to have several
290 duplicate keys in the hash table. This function may be used to
291 find all of the keys from the hash.
293 Added user_context arguments to the SilcHashFunction,
294 SilcHashCompare and SilcHashDestructor to deliver user specified
297 Added new fuctions silc_hash_table_find[_all]_ext to do
298 extended lookup with specified hash and compare functions and
299 specified user contexts.
301 Added new function silc_hash_table_add_ext to add the key
302 with specified hash function and user context.
304 Added new function silc_hash_table_foreach to traverse all
305 entrys in the hash table. Added SilcHashForeach callback
308 Added new function silc_hash_table_del_by_context to delete
309 the entry only if the context associated with the key matches.
311 Affected files are lib/silcutil/silchashtable.[ch].
313 * Removed silc_hash_[server/client/channel]_id and added just
314 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
315 silc_hash_id_compare to compare two ID's using as the hash table
316 comparison function. Added also silc_hash_data to hash
317 binary data and silc_hash_data_compare to compare it.
319 * Removed silc_idlist_find_client_by_hash as it is not needed
320 anymore. Affected file silcd/idlist.[ch].
322 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
323 to use internally the SilcHashTable. The new ID Cache is a lot
324 faster than the old one. Some of the ID Cache interface was also
325 rewritten and obsolete and stupid functions were removed.
327 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
329 * Added entry_count field to the SilcHashTable to keep the number
330 of the entries in the table. Implemented the function
331 silc_hash_table_rehash. Added new function
332 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
334 Fixed a minor bug in silc_hash_table_free.
336 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
337 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
338 into the lib/silcutil/silcutil.[ch].
340 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
342 * Implemented a collision resistant hash table into the
343 lib/silcutil/silchashtable[ch]. See the header and the source
344 for the SilcHashTable API.
346 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * Merged dotconf version 1.0.2 into lib/dotconf.
350 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
352 * Do not compile anything in lib/silcsim/* if the SIM support
353 is not enabled. The tree should now compile without problems
356 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * Compiled the SILC under cygwin. Compiled and tested briefly
359 without problems. More tests needed. The SIMs didn't compile
362 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
364 * Fixed possible crash in silc_get_username in the
365 lib/silcutil/silcutil.c.
367 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
369 * Fixed a va_arg in silc/client_ops.c.
371 * Oops, RC5 routines were named AES and caused some problems
372 when not using SIM's. Affected file lib/silccrypt/rc5.c.
374 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
376 * Added new SilcIDIP structure into the lib/silccore/id.h and
377 replaced the old `ip' fields from all SILC ID's to that type.
378 This is a step towards IPv6 support.
380 The silc_id_get_len takes now the ID as an extra argument.
381 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
382 both IPv4 and IPv6 based ID's.
384 The affected files are lib/silccore/id.[ch] and other files
385 around the tree using these routines.
387 * Removed the ID length arguments in server from various
388 silc_server_send_notify_* routines -> they are not needed
391 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
393 * Fixed memory leak in silc_encode_pem_file in the file
394 lib/silcutil/silcutil.c.
396 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
398 * Check minor version as well in the SKE. Affected files are
399 silcd/protocol.c and lib/silcclient/protocol.c.
401 * Added --identifier option to the server so that an identifier
402 can be when creating the public key for the server. Affected
403 file is silcd/silcd.c.
405 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
406 lib/silccrypt/silcpkcs.c.
408 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
410 * Register default ciphers and stuff when using -C option with
411 the server. Affected file sildc/silcd.c.
413 * Put back the servers public key filename format, it is better
414 than the new one. For now, the client keys are saved with the
415 new filename format. The affected file silc/client_ops.c.
417 * Implemented the Cipher API for the rest of the ciphers that
418 did not implement it or implemented it the wrong way.
420 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
422 * Register default ciphers and stuff when using the -S option
423 in the client. Affected file silc/silc.c. Same also when
424 creating new key pair with -C option.
426 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
428 * Fixed the silc_verify_public_key client operation function to
429 save the public keys differently. The fingerprint is now
430 used as filename and not the hostname. This way also the
431 client keys are saved uniquely and not with hostnames. The
432 affected file is silc/client_ops.c.
434 * Trimmed the silc_hash_fingerprint function to remove extra
435 whitespaces from the end of the fingerprint. The affected
436 file is lib/silccrypt/silchash.c.
440 * Added silc_cipher_register_default function to register all
441 default ciphers. It can be used when configuration files
442 does not exist and the application does not want any specific
443 ciphers in any specific order.
445 The SilcDList is now used as silc_cipher_list dynamically
446 allocated cipher list. Removed the static list all together
447 and now all ciphers must be allocated to the dynamic list.
448 The silc_cipher_alloc routine was changed to check only the
451 All silc_cipher_* routines that used to return int returns
454 The affected files lib/silccrypt/silccrypt.[ch].
456 * The same thing was done to silc_hash_* as for silc_cipher_*
457 routines. Affected files lib/silccrypt/silchash.[ch].
459 * The same thing was done to silc_pkcs_* as for silc_cipher_*
460 routines. Affected files lib/silccrypt/silcpkcs.[ch].
461 Added also silc_pkcs_[un]register[_default] functions.
462 Removed the data_context from the PKCS API.
464 * Added silc_hmac_register_default function to register default
465 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
466 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
467 to unregister all hmacs at once.
469 * Register the default ciphers, hash functions, PKCSs and HMACs
470 if client's configuration file does not exist. The affected
473 * The client did not load the hash functions from the SIM
474 modules at all. Added support for this. Affected file is
477 * When decoding public key with silc_pkcs_public_key_decode, check
478 the supported algorithm only if PKCS are registered. Affected
479 file lib/silccrypt/silcpkcs.c. The same was done with the
480 silc_pkcs_private_key_decode.
482 * Fixed the SILC List routines to keep the list always in order.
483 It used to change the list's order when traversing the list but
484 not it preserves the order. Affected file lib/trq/silclist.h.
486 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
488 * Added the client library to use the SilcSocketConnection's
489 reference counter (by silc_socket_dup) to prevent the bug that
490 the socket object may be freed underneath async operation.
492 * The name resolv library checking fixes in the configure.in.pre.
495 * Created new version of the protocol drafts for future
496 development. The -03 drafts are the ones that will be changed
497 in the trunk now and the -02 will remain as they are.
499 * Send list of CUMODE notifys to the router when announcing
500 the channel users to the router. Affected file silcd/server.c.
501 If the router receiving channel founder CUMODE for a channel
502 that already has channel founder it will send CUMODE notify
503 to the sender to remove the channel founder rights from the
504 announced client. Affected file silcd/packet_receive.c.
506 * The CUMODE notify may now use Server ID as well as the entity
507 who changes the mode. Updated protocool specs.
509 * Updated INSTALL and README files.
511 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
513 * New web pages in the http://silc.pspt.fi. The pages was
518 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
520 * Implemented the [DenyConnectin] config section in the server.
521 Added silc_server_config_denied_conn to check whether incoming
522 connection is denied. Affected file silcd/serverconfig.[ch].
524 * Do not check the ports when checking the incoming configuration
525 data if the port is 0, meaning any. Affected file is
526 silcd/serverconfig.c.
528 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
530 * Fixed buffer overflow in silc_string_compare in the file
531 lib/silcutil/silcutil.c.
533 * Fixed double free in silc_server_command_leave in the file
536 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
538 * Fixed the version checking in the server. Affected file is
541 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
543 * Fixed the configuration data fetching when accepting new
544 connections in the server. Affected file silcd/server.c.
546 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
548 * Added `sender_entry' argument to the function
549 silc_server_packet_relay_to_channel so that we can check
550 whether some destination actually belongs to the same route
551 the sender belongs (ie, we must not resend the packet to the
552 sender). Affected file silcd/packet_send.[ch].
554 * Added `servername' field to the SilcClientEntry in the server
555 to hold the name of the server where client is from. Affected
556 file is silcd/idlist.h.
558 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
560 * Moved the channel message encrypting in the router betwen
561 router connections from silc_server_channel_message to the
562 silc_server_packet_relay_to_channel since we want to check
563 whether we have anybody channel before encrypting anything.
564 Affected files silcd/packet_[receive/send].c.
566 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
568 * Fixed the [AdminConnection] server config section to support
569 multiple entries. Affected file silcd/serverconfig.c.
571 * Added support into the server to check the validity of the
572 incoming connection before executing any KE or authentication
575 * The connection configuration is now saved to the KE and
576 connection auth protocol contexts and not fetched anymore in
577 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
579 * The local hosts listenning address and port is also resolved
580 now when starting the server. We want to have the socket object
581 to include the real address and port for the listener. Added
582 new function silc_net_check_local_by_sock into the files
583 lib/silcutil/silcnet.[ch].
585 * Fixed a broadcast bug in server -> do not broadcast if we
588 * Fixed a routing bug. Do not route broadcast packets ever.
589 Broadcast packets must be processed always and not routed since
590 they may be destined to some other host than yourself and thus
591 would get routed without no good reason. Affected file is
594 * Added function silc_server_config_is_primary_route to check
595 whether primary router connection has been configured (a router
596 configuration that we are initiating). If there is not, we
597 will assume that there is only two routers in the SILC network
598 and we will use the incoming router connection as our primary
599 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
601 * Changed the order of the broadcasting. Broadcast _after_ the
602 packet has been processed not before. Affected file is
605 * Fixed a [ClientConnection] parsing bug. The port was never
606 parsed correctly thus resulting to port 0. Affected file
607 silcd/serverconfig.c.
609 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
610 argument and did not set the broadcast packet flag. Affected
611 file silcd/packet_send.c. Fixed same bug in the function
612 silc_server_send_notify as well.
614 * If we receive NEW_ID packet for our own ID in the server, ignore
617 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
621 * Removed the nickname from the Private Message Payload.
622 Updated the code and the protocol specs.
624 * Updated protocol specs for submitting to the IETF.
626 * Tweaked the Random Number Generator a bit. Affected file
627 lib/silccrypt/silcrng.c. Exported a new function
628 silc_rng_[global]_add_noise which can be used to add more
631 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
633 * Do not parse packets with different timeout when protocol
634 is active -> may cause problem with rekey. Affected file
637 * When server receives signoff notify it must not create
638 new channel key if the client is on any channels since the
639 sender of the signoff notify will create it.
641 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
643 * Added printing of error messages during SKE protocol from the
644 failure packet sent by server during SKE. Affected file
647 * Removed the client's failure_callback handling with timeout
648 and handle it immediately when received.
650 * The SKE library returned wrong type in SUCCESS and FAILURE
651 packets. They must be 32 bit MSB not 16 bit MSB.
653 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
655 * Ok, rewrote the logic of the re-key and now it seems to work.
656 I tested it on high traffic with frequent re-keys without
657 problems. Added hmac_receive (and renamed hmac to hmac_send)
658 in SilcClientConnection in lib/silcclient/client.h and
659 in SilcIDListData in silcd/idlist.h. Also, removed the
660 SilcPacketParserContext's cipher and hmac fields as they are
661 not needed anymore and actually caused some problems when
662 the ciphers and hmac's changed underneath the packet parser.
664 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
666 * If re-key protocol is active then process the incoming packets
667 synchronously since we must assure that icoming packets encrypted
668 with the old key is processed before the new keys is set to
669 use. This is true other packets than for REKEY packets.
670 Affected file silcd/server.c. The same was done to client library
671 as well, affected file lib/silcclient/client.c.
673 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
675 * Fixed bug in client and server to accept the force send if
676 the packet is send from silc_[server/client]_packet_process
677 function. Otherwise the packets are never delivered, oops.
679 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
681 * Disable force sending of packets when REKEY protocol is active.
682 We must assure that no packet is sent directly when rekey is
683 performed. All packets must be sent through packet queue.
684 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
685 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
686 function is silc_[server/client]_packet_send_real to check
689 * Replaced the SIM paths from example config files to
690 /usr/local/modules. Also, make install creates now
691 /usr/local/silc/logs directory to hold all the SILC server
694 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
696 * Made the configure.in.pre work on Solaris. Patch by salo.
698 * Made all ciphers compatible with non-x86 machines. Defined
699 CBC mode macros into lib/silccrypt/ciphers_def.h.
701 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
703 * Fixed the make install.
705 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
707 * When MAC computation fails the silc_packet_decrypt returned 0
708 even though it was supposed to return -1. Fixed this. The
709 affected file is lib/silccore/silcpacket.c.
711 * Do not replace the config files in /etc/silc (in make install)
712 if they already exist. Affected file ./Makefile.am.
714 * Do not send re-key packets immediately but through packet queue.
715 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
717 * Changed silc_net_check_host_by_sock to return FALSE if the
718 IP/DNS could not be resolved. Though, it returns the IP address
719 now even if it could not resolve it (but returns also FALSE).
720 Affected file lib/silcutil/silcnet.[ch].
722 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * Added silc_pkcs_decode_identifier to decode the public key's
725 identifier. Affected file lib/silccrypt/silpkcs.[ch].
726 Added also silc_pkcs_free_identifier. Added also new context
727 SilcPublicKeyIdentifier.
729 * Added -S option to the silc client. It is used to dump the
730 contents of the specified public key file.
732 * Changed the PKCS api to return the public key length when
733 setting the public key.
735 * Fixed a fatal bug in the public and private key file loading.
736 Affected file lib/silccrypt/silcpkcs.c.
738 * Execute the packet parsing for client with zero (0) timeout
739 if the protocol is active. Affected file silcd/server.c.
741 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
743 * Made the key generation options to the silcd program. Added
744 -C option, equivalent to client's option.
746 * Added new [ServerKeys] config section to the server. It
747 configures the server's public and private key.
749 * Defined generic Public Key Payload into the protocol
750 specification to send specific type of public keys and
753 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
754 public key or certificate.
756 * Implemented the GETKEY command to the server and to the
757 client library and on user interface.
759 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Made preliminary `make install' work.
763 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
765 * Added SilcServerRekey context into silcd/idlist.h.
767 * Added the PFS support as defined in the specification to the
768 SKE protocol. Affected files lib/silcske/*.c.
770 * Added `ske_group' field to the SilcServerRekey context to hold
771 the number of the SKE group that is used with PFS in re-key.
772 Affected file silcd/idlist.h.
774 * Added PFS re-key support to the server. Affected file is
777 * Added silc_protocol_cancel to cancel execution of the next
778 state of the protocol. Affected file is
779 lib/silccore/silcprotocol.[ch].
781 * Added the re-key support with and without PFS to the client
782 library. Re-key is performed once in an hour, by default.
784 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
785 Added silc_client_rekey_callback and silc_client_rekey_final.
786 Affected files are lib/silcclient/protocol.[ch] and
787 lib/silcclient/client.[ch].
789 * Removed the `hmac_key' and `hmac_key_len' fields from the
790 SilcClientConnection structure; not needed. Affected file is
791 lib/silcclient/client.h.
795 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
797 * Do not ask whether user wants to use the negotiated private key
798 for private messages, just use it. Affected file is
799 silc/local_command.c.
801 * Added `send_enc_key' and `enc_key_len' fields to the
802 SilcIDListData structure since they are needed in the re-key
803 phase. Affected file is silcd/idlist.[ch].
805 * Implemented the simple re-key protocol into the server.
806 Affected files silcd/server.c and silcd/protocol.[ch]. The
807 re-key will be performed once in an hour, by default.
809 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
810 Added silc_server_rekey, silc_server_rekey_callback and
811 silc_server_rekey_final.
813 * Removed Tunneled flag from the protocol. Updated the code
814 and the specifications.
816 * Adde `pfs' field to the SilcIDListData to indicate whether
817 the PFS is to be performed in the re-key. Affected file is
820 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
822 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
823 int64 of at least the xintXX size. If void * is less that 4
824 bytes uint32 * will be used. Defined bool as boolean.
826 * Changed _ALL_ unsigned long and unsigned int to uint32,
827 unsgined short to uint16 in the source tree.
829 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
830 not handle clients that has entry->data.registered == FALSE.
831 They are not in the network anymore. Affected file is
834 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Implemented the sending of the SERVER_SIGNOFF notify in the
837 server. Affected file is silcd/server.c.
839 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
840 Added also silc_notify_payload_encode_args into the
841 lib/silccore/silcnotify.[ch].
843 * Implemented ther SERVER_SIGNOFF notify handling in the server.
844 Affected file silcd/packet_receive.c.
846 * Implemented the SERVER_SIGNOFF notify handling in the client
847 library. Affected file lib/silcclient/client_notify.c. Also,
848 implemnted the printing of the SERVER_SIGNOFF info to the
849 application. Affected file silc/client_ops.c.
851 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
852 if the deleting was successful. Affected file silcd/idlist.[ch].
854 * Added support for public key authentication in the connection
855 authentication protocol in the client library. Affected file
856 lib/silcclient/protocol.c.
858 * Changed the server's silc_idlist_get_clients_by_* interface
859 to support already allocated array so that new entries may be
860 added to pre-allocated array. Affected file silcd/idlist.[ch].
861 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
864 * All command reply functions in the server now calls the
865 pending command callback even if error occured. This way the
866 error will be delivered to the client as well. Affected files
867 silcd/command.c and silcd/command_reply.c.
869 * Fixed INFO command to return local server's info if no server
870 was provided. Affected file lib/silcclient/command.c.
872 * Removed RESTART command for good. Updated the code and the
875 * Rewrote parts of the task system. It is a bit simpler now.
876 Removed unsued task priorities. The affected files are
877 lib/silcutil/silctask.[ch].
879 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
881 * Moved the USERS printing from the library to the application.
882 Affected files lib/silcclient/command.c and silc/client_ops.c.
884 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
888 * Added channel key re-key support. The re-key is perfomed
889 only by the router and is done once in an hour. Added `rekey'
890 field to the SilcChannelEntry in the server. Affected files
891 silcd/server.c and silcd/idlist.h.
893 * Added silc_task_unregister_by_context into the file
894 lib/silcutil/silctask.[ch].
896 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Added SILC_UMODE_GONE mode to indicate when the client is not
899 present in the SILC network. Added also support to the local
900 command AWAY that will set this mode. Added support of showing
901 "xxx is gone" in WHOIS command. The USERS command shows the
904 * Fixed setting server and router operator privileges in the
905 server's UMODE command. Affected file silcd/command.c.
907 * Merged the SKE KE1 and KE2 payloads into one payload. The
908 new KE payload is equivalent to the old KE2 payload.
910 Cleaned up the SKE Start Payload parsing. It now uses the
911 simple buffer unformatting to do the parsing. A lot faster
914 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
915 to the SKE that is used to indicate whether both of the SKE
916 parties should perform authentication. By default only the
917 responder performs authentication. By setting this flag also
918 the initiator must do authentication. By default it is unset
919 since in normal SKE case, client to server connection, only
920 the responder should do authentication. When doing SKE between
921 two clients both should perform authentication. Updated the
922 code and the protocol specs.
924 * A little fix to IDENTIFY command in the server. Search the
925 client first by hash not nickname. Affected file is
928 * Fixed the silc_client_close_connection to support closing
929 the client to client connections wihtout deleting too much
930 data. Affected file lib/silcclient/client.c.
932 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
933 are received if protocol used to be active but is not anymore
934 the application would crash due to NULL pointer dereference.
935 Affected files silcd/server.c and lib/silcclient/client.c.
937 * Added `hash' field to the SilcClientConnection to include
938 the hash function negotiated in the SKE protocol.
940 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
941 to set the channel founder authentication data. A client can
942 claim the founder rights later by providing the authentication
943 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
944 This way the channel founder can regain the channel founder
945 privileges even it is left the channel. This works only on
946 local server and the client must be connected to the same
947 server to be able to regain the founder rights. Updated the
948 protocol specs accordingly.
950 Added support to the CMODE command in the client to set the
951 founder auth data. Read the README to see how to set it.
953 Added support to the CUMODE command to claim the founder
954 rights. Read the README to see how to do it.
956 Added support for the founder authentication to the Channel
957 Entry in the server. Affected file silcd/idlist.h.
959 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
960 server's CMODE command. Affected file silcd/command.c.
962 * Added the following new functions into lib/silccore/silcauth.[ch]:
963 silc_auth_get_method and silc_auth_get_data.
965 * The server now saves the remote hosts public key to the
966 SilcIDListData pointer. Affected file silcd/protocol.c.
968 * The normal server now does not remove the channel entry from
969 the cache if the founder authentication data is set. It used
970 to remove it if the founder was the last one on the channel on
971 the server and left the channel. The auth data is saved and
972 if the channel is re-joined later the old entry is used with
973 the old auth data. Affected files silcd/command_reply.c and
976 * Removed the `pkcs' field from the SilcIDListData structure
977 in the server; it is not used. Affected file silcd/idlist.h.
979 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
981 * Fixed packet processing on slow links. Partial packets were
982 never re-processed because the incoming data buffer was cleared
983 by the application. Application must not directly clear the
984 sock->inbuf, the packet processing routines handle it. Fixed
985 this in client library and in server.
987 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
989 * Fixed the WHOIS and IDENTIFY send reply function to really
990 check whether to send list or just one entry. Affected file
993 * Cleaned up the LEAVE command's channel key distribution. The
994 affected file silcd/command.c.
996 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
997 can enforce the channel mode as well. In that case the ID
998 includes the ID of the server. The code now enforces the
999 mode change if the router have different mode than the server.
1001 * The notify client operation with CMODE_CHANGE notify can now
1002 return NULL client_entry pointer if the CMODE was not changed
1003 by client. Application must check for this.
1005 * Added <Server ID> argument to INFO command to support server
1006 info fetching by Server ID.
1008 * Added silc_server_announce_get_channel_users to get assembled
1009 packets of channel users of the specified channel. Affected
1010 file silcd/server.[ch].
1012 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1013 was freed underneath the ID Cache.
1015 * Re-announce clients when the server received CHANNEL_CHANGE
1016 notify from the router. Affected file silcd/packet_send.c.
1018 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1020 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1021 crashed since it did not handle the fact that there is no cipher
1022 called "3" and didn't check the error condition. Now fixed.
1024 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1025 flag. It can be used to send message requests.
1027 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1029 * Implemented the RESTART command in the client.
1031 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1032 notice type messages. Added notice printing to the user
1035 * The channel keys are not re-generated if the channel's mode
1036 is PRIVKEY, ie private key on the channel exists. Affected
1037 files silcd/server.c and silcd/command.c.
1039 * Fixed a little bug in channel message delivery when channel
1040 private keys are set in the server. Affected file is
1041 silcd/packet_send.c.
1043 * Changed the setting on channel->on_channel = TRUE from the
1044 silc_client_save_channel_key to the JOIN command reply. The
1045 key payload is not received if the private channel key is set.
1046 Affected file lib/silcclient/command_reply.c and the
1047 lib/silcclient/client_channel.c.
1049 * When the CMODE_CHANGE notify is sent and the channel private
1050 key mode is removed the channel key must be re-generated in
1051 other cells as well. Added this support for the router in the
1052 silcd/packet_receive.c.
1054 * Added new local command NOTICE to send notice message on
1055 channel. Affected file silc/local_command.[ch].
1057 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1059 * Added new local command ME to the client. It is used to send
1060 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1061 some action. Affected file silc/local_command.[ch].
1063 * Changed channel_message and private_message client operations
1064 to deliver the message flags to the application. Added also
1065 the `flags' arguments to the silc_client_send_channel_message
1066 and silc_client_send_private_message functions. Affected file
1069 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1071 * Redefined the Private Message Payload to support private message
1072 keys and to support the new private message flags. Updated
1073 the protocol specs. Flags makes it possible to have for example
1074 CTCP style messages.
1076 * Added new type SilcPrivateMessagePayload and defined an API
1077 for it in the lib/silcclient/silcprivate.[ch].
1079 * Tested private message private keys successfully. Tested the
1080 private message key set, unset and list commands with the new
1083 * Redefined the Channel Message Payload to include the channel
1084 message flags (equal with private message flags) to support
1085 for example CTCP style messages.
1087 * Defined some of the message (for channel and private message)
1088 flags. Updated the protocol specs and added the flags to the
1089 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1091 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1093 * Added SilcKeyAgreementStatus type to the key agreement routines
1094 to indicate the current status and error if one occured.
1095 The status types are defined in the lib/silcclient/silcapi.h.
1097 * Added new local command KEY that is used to set and unset private
1098 keys for channels, set and unset private keys for private messages
1099 with remote clients and to send key agreement requests and
1100 negotiate the key agreement protocol with remote client. The
1101 key agreement is supported only to negotiate private message keys,
1102 it currently cannot be used to negotiate private keys for channels,
1103 as it is not convenient for that purpose.
1105 * Fixed a minor pending callback setting bug in the function
1106 silc_client_get_client_by_id_resolve, now the function works.
1107 Affected file lib/silcclient/idlist.c.
1109 * Added function silc_net_get_local_port to get local bound
1110 port by socket. Added to lib/silcutil/silcnet.[ch].
1112 * Added `sockets' and `sockets_count' fields to the SilcClient
1113 object. They hold the sockets of the listenning sockets in
1114 the client. Listenning sockets may be for example the key
1115 agreement server. Affected file lib/silcclient/client.[ch].
1116 Added functions the silc_client_add_socket and the
1117 silc_client_del_socket. They are exported to the application
1120 * Added ~./silc/clientkeys to support other client's public keys.
1122 * Renamed verify_server_key client operation to verify_public_key
1123 and added one argument to indicate the type of the connection
1124 (server, client etc.).
1126 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1128 * Added silc_server_connection_auth_request to handle the
1129 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1130 silcd/packet_receive.[ch].
1132 * Added silc_server_send_connection_auth_request into the
1133 silcd/packet_send.c to send the connection auth request packet.
1135 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1138 * Fixed the public key authentication in responder side in the
1139 server. The `auth_data' pointer includes the SilcPublicKey
1140 not the path to the public key. Affected file silcd/protocol.c.
1142 * Implemented the public key authentication in the initiator side
1143 in the server. Affected file silcd/protocol.c.
1145 * Removed the [RedirectClient] config section from the server
1146 configuration. Is not needed and I don't want to implement it.
1148 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1150 * Cleaned up the CMODE command in the server. It now works
1151 correctly and supports all the modes defined in the protocol.
1152 Affected file is silcd/command.c.
1154 * Added `hmac_name' field to the SilcChannelEntry in the server
1155 to hold the default HMAC of the channel. It can be set when
1156 creating the channel (with JOIN command). Affected files
1159 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1160 type to indicate the change of the current cipher and hmac
1161 on the channel. Client can safely ignore the <cipher> argument
1162 (if it chooses to do so) since the CHANNEL_KEY packet will
1163 force the channel key change anyway. The <hmac> argument is
1164 important since the client is responsible of setting the new
1165 HMAC and the hmac key into use.
1167 * Fixed the CMODE command in the client library as well.
1169 * Tested CMODE command in router environment successfully.
1171 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1173 * Show the version of the remote client (or server) when connecting
1174 to the server. It is logged to the log file. Affected file
1175 is silcd/protocol.c.
1177 * Fixed the KILLED notify handling in the client library. The
1178 client must be removed from all channels when receiving the
1181 Also, do not remove the client entry when giving the KILL
1182 command but when the KILLED notify is received.
1184 * Removed silc_idlist_find_client_by_nickname from the server.
1185 Not needed anymore. Affected files silcd/idlist.[ch].
1187 * Implemented the CHANNEL_CHANGE notify type handling to the
1188 server. Affected file silcd/server.c.
1192 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1194 * Added silc_server_send_notify_invite to send the INVITE
1195 notify between routers.
1197 * Implemented the INVITE command correctly to the server.
1199 * Implemented the INVITE notify type handling in the server.
1201 * Implemented the INVITE command to the client library and on the
1204 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1206 * Added function silc_server_get_client_resolve to find the
1207 client entry by ID from all ID lists and then resolve it
1208 (using WHOIS) if it cannot be found. Affected file is
1211 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Implemented the BAN command to the client library.
1215 * The JOIN command in the server now checks the invite list
1218 * Changed the silc_command_reply_payload_encode_va and the
1219 silc_command_payload_encode_va to support that if argument is
1220 NULL it ignores and checks the next argument. Affected file
1221 lib/silccore/silccommand.c.
1223 * Added silc_server_send_notify_ban to send the BAN notify
1224 type between routers.
1226 * Chaned the silc_notify_payload_encode to support that if
1227 argument is NULL it ignores and checks the next argument.
1228 Affected file lib/silccore/silcnotify.c.
1230 * Tested ban lists in router environment successfully.
1232 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1234 * Implemented BAN command to the server, in silcd/command.[ch].
1236 * Removed the BAN and INVITE_LIST modes from the CMODE command
1239 * Added function silc_string_match to regex match two strings.
1240 Affected files lib/silcutil/silcutil.[ch].
1242 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1244 * Redefined parts of the SilcChannelEntry in the server to support
1245 the new ban and invite lists.
1247 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1249 * Redefined the INVITE command. The same command can be used to
1250 invite individuals to the channel but also to manage the invite
1251 list of the channel (to add to and remove from the invite list).
1252 Updated the protocol specs.
1254 * Added new command SILC_COMMAND_BAN that can be used to manage
1255 the ban list of the channel. Updated the protocol specs.
1257 * Removed the channel modes: the SILC_CMODE_BAN and the
1258 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1259 in the CMODE command. The equivalent features are now available
1260 using INVITE and BAN commands. Updated the protocol specs.
1262 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1263 in the network about change in the current ban list. The notify
1264 type is not used by the client.
1266 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1267 support the invite lists.
1269 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Added new function silc_string_regexify that converts string
1272 including wildcard characters into regex string that can
1273 be used by the GNU regex library. Added into the file
1274 lib/silcutil/silcutil.[ch].
1276 Added silc_string_regex_combine to combine to regex strings
1277 into one so that they can be used as one regex string by
1278 the GNU regex library. Added into the file
1279 lib/silcutil/silcutil.[ch].
1281 Added silc_string_regex_match to match two strings. It returns
1282 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1284 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1286 * Imported GNU regex to the soruce tree into lib/contrib.
1287 Fixed some compiler warning from the regex.c.
1289 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1291 * Fixed MOTD command in the server to work in router environment.
1293 * Fixed the MOTD command in the client library to support
1294 the server argument in the command.
1296 * Added `nickname_len' argument to the silc_idlist_add_client
1297 in the server, as the `nickname' argument may be binary data
1300 * Added silc_idlist_get_channels to return all channels from
1303 * Implemented LIST command to the server. Affected file is
1306 * Implemented the LIST command to the client library and on the
1309 * Added [<user count>] argument to the LIST command reply.
1310 With private channels the user count is not shown.
1312 * Updated TODO and README.
1314 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1316 * The client entry's data.registered must be TRUE even with
1317 global client entry on global client list. The data.registered
1318 is used to check whether the client is anymore in the network,
1319 for example with WHOWAS command so it must be valid.
1321 * Fixed the WHOWAS command in the server. It now actually works
1322 in router environment. Added function into silcd/command_reply.c
1323 silc_server_command_reply_whowas_save.
1325 * Added silc_idlist_purge function to the silcd/idlist.c
1326 to periodically purge the ID Cache.
1328 * Fixed INFO command in the server. It works now in router
1329 environment. Added <server name> argument to the INFO command
1330 reply. Updated the protocol specs.
1332 * Fixed minor bug in silc_idcache_purge to not purge if the
1333 expire value is zero.
1335 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1336 they were buggy because of the WHOWAS information.
1338 * Fixed local command MSG to handle the async resolving of
1339 the remote client properly. It used to fail the first MSG.
1340 Affected file silc/local_command.c.
1342 * Added `data_len' field to SilcIDCache context.
1344 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1346 * Update TODO. Todo in commands in the server.
1348 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1350 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1351 used by routers as broadcast packet to inform other routers
1352 about the changed user mode.
1354 Implemented the notify handling in the server. Affected file is
1355 silcd/packet_receive.c. Added the function
1356 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1358 * Added new generic Channel Payload and deprecated the New Channel
1359 Payload. The New Channel Payload is now the generic Channel
1362 * Added new argument `mode' to the silc_server_send_new_channel
1363 as it is required in the Channel Payload now.
1365 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1366 and created a new and real SilChannelPayload to represent the
1367 new generic Channel Payload. Implemented the encode/decode
1368 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1370 * Added silc_server_get_client_channel_list to return the list
1371 of channels the client has joined for WHOIS command reply.
1372 Affected file silcd/server.[ch].
1374 * Implemented the channel list sending in the WHOIS command reply
1375 in server and in the client.
1377 Implemented the channel list displaying on the user interface
1378 as well. Affected file silc/client_ops.c.
1380 * Added silc_channel_payload_parse_list to parse list of Channel
1381 Payloads. It returns SilcDList list of SilcChannelPayloads.
1382 Client for example can use this function to parse the list of
1383 channels it receives in the WHOIS command reply. The caller
1384 must free the list by calling silc_channel_payload_list_free.
1385 Affected files lib/silccore/silcchannel.[ch].
1387 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1389 * Added one new argument <user mode> to the WHOIS command reply
1390 to return the mode of the user in SILC. Updated the protocol
1393 Implemented it to the server and client.
1395 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Fixed the mode printing on the user interface on joining.
1398 Affected file silc/client_ops.c.
1400 * Implemented the UMODE command and user modes in general to the
1401 client library and to the user interface.
1403 * Implemented the UMODE command to the server.
1405 * The server now sends UNKNOWN_COMMAND error status if client sends
1406 unknown command. Affected file silcd/command.c.
1408 * All server commands now handle the command identifier the right
1409 way when sending the command reply to the client. The client can
1410 use to identify the command replies with the identifier.
1412 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1414 * Added silc_server_get_client_route to resolve the route to
1415 the client indicated by the client ID. Affected file is
1418 * Added silc_server_relay_packet as general function to relay
1419 packet to arbitrary destination. This deprecates functions
1420 like _send_private_message_key, _relay_notify etc. Affected
1421 file is silcd/packet_send.[ch].
1423 Removed silc_server_send_key_agreement,
1424 silc_server_send_private_message_key and
1425 silc_server_packet_relay_notify functions from the file
1426 silcd/packet_send.[ch].
1430 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1431 server. Affected file silcd/packet_receive.[ch].
1433 * Implemented the KILL command to the client. Implemented the
1434 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1435 Affected files lib/silcclient/command[_reply].c and
1436 lib/silcclient/client_notify.c. Implemented the KILL notify
1437 printing in the user inteface.
1439 * Fixed a lot silc_parse_nick memory leaks from the client
1440 library in the file lib/silcclient/command.c.
1442 * Changed the silc_server_send_notify_on_channels's `sender'
1443 argument from SilcSocketConnection to SilcClientEntry to
1444 check the sender as entry and not as connection object and not
1445 to send to the client provided as argument. The affected file
1446 is silcd/packet_send.[ch].
1448 * The notify packets that are destined directly to the client used
1449 to not to be processed by the server. Now changed that and the
1450 server processes all notify packets. After relaying the packet
1451 to the client the notify packet is processed in the server.
1453 * The silc_server_free_client_data now checks whether there is
1454 pending outgoing traffic for the client and purges the data to
1455 the network before removing the client entry.
1457 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1459 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1460 an client is killed from the SILC Network. Updated the protocol
1463 Added new function silc_server_send_notify_killed to the
1464 silcd/packet_send.[ch].
1466 * Added function silc_server_packet_relay_notify to relay notify
1467 packets that are destined directly to a client. In this case
1468 the server does not process the notify packets but merely relays
1469 it to the client. Affected file silcd/packet_send.[ch].
1471 Added also silc_server_packet_process_relay_notify to check
1472 whereto relay the notify. Affected file is
1473 silcd/packet_receive.[ch].
1475 * Implemented the KILL command to the server.
1479 * Added the backup schema desgined last fall to the protocol
1480 specs for everyone to see. The specification is in the
1481 *-spec-xx.txt draft and the packet type definitions for the
1482 backup routers is in *-pp-xx.txt draft. Thusly, added also
1483 new packet type SILC_PACKET_CELL_ROUTERS.
1485 * A big security problem in the implementation discovered. The
1486 signoff of an client did not cause new channel key generation
1487 which it of course should've done. The channel keys must be
1488 always re-generated when client leaves (or signoffs) the channel.
1489 The silc_server_remove_from_channels funtion now handles
1490 the channel key re-generation.
1492 * Added `sender' argument to the silc_server_send_notify_on_channels
1493 to not to send the client provided as argument. Affected file
1494 silcd/packet_send.[ch].
1496 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1498 * Implemented OPER and SILCOPER commands into the server and
1501 * Added silc_auth_verify and silc_auth_verify_data to verify
1502 the authentication directly from the authentication payload.
1503 It supports verifying both passphrase and public key based
1504 authentication. Affected file lib/silccore/silcauth.[ch].
1506 * Added `hash' field to the SilcIDListData structure. It is the
1507 hash negotiated in the SKE protocol. Affected file is
1510 * Slight redesigning of the SilcAuthPayload handling routines.
1511 Do not send SilcPKCS but SilcPublicKey as argument.
1513 * Implemented the public key authentication support to the
1514 serverconfig. The public key is loaded from the provided path
1515 and saved as authentication data to void * pointer. Thus,
1516 changed the unsigned char *auth_data to void *auth_data;
1518 * Fixed SHUTDOWN command to send the reply before the server
1519 is shutdown. :) Affected file silcd/command.c.
1521 * Fixed fatal bug in CONNECT command. The hostname was invalid
1522 memory and server crashed. Affected file silcd/command.c.
1524 * Fixed fatal bug in CLOSE command. The server_entry became
1525 invalid but was referenced later in the command. Affected file
1528 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1530 * Fixed fatal bug in failure packet handling. Server ignored
1531 the failure and thus crashed when it came.
1535 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1538 that the command may be executed only once in (about) 2 seconds.
1539 The old SILC_CF_LAG flag is same but allows command bursts up
1540 to five before limiting.
1542 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1543 server code. Various commands now includes the CF_LAG_STRICT
1544 flag to disallow any kind of miss-use of the command.
1546 * Fixed the silc_buffer_unformat to not to allocate any data
1547 if the length of the data is zero. It used to allocate the
1548 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1550 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1552 * Changed the format of AdminConnection configuration section
1553 in the server. Added username of the admin to the format.
1554 Affected files silcd/serverconfig.[ch].
1556 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1557 to return admin configuration data by host, username and/or
1560 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1562 * Implemented WHOWAS command to the server. Added the functions:
1564 silc_server_command_whowas_parse,
1565 silc_server_command_whowas_send_reply,
1566 silc_server_command_whowas_from_client and
1567 silc_server_command_whowas_from_server
1569 * Added <Client ID> argument to the WHOWAS command reply. Updated
1570 the protocol specs accordingly.
1572 * Implemented WHOWAS command and command_reply to the client
1575 Implemented the WHOWAS printing on the user interface.
1577 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1579 * Added new argument to the WHOWAS command reply, the real name.
1580 It is an optional argument. Updated the protocol specs.
1582 * Added SilcIDCacheDestructor callback that is registered when
1583 the SilcIDCache is allocated. The callback is called when
1584 an cache entry in the ID Cache expires, or is purged from the
1585 cache. Added into lib/silccore/idcache.[ch].
1587 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1588 to destruct the client entries when the cache entry expires.
1589 Other ID Cache's in server and in the client library ignores
1592 * If the ID Cache entry's `expire' field is zero then the entry
1593 never expires. Added boolean `expire' argument to the
1594 silc_idcache_add function in the lib/silccore/idcache.[ch].
1595 If it is TRUE the default expiry value is used.
1597 * Added silc_server_free_client_data_timeout that is registered
1598 when client disconnects. By default for 5 minutes we preserve
1599 the client entry for history - for WHOWAS command.
1601 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1603 * Added support to the server to enforce that commands are not
1604 executed more than once in 2 seconds. If server receives
1605 commands from client more frequently, timeout is registered
1606 to process the commands. Affected file silcd/command.c.
1607 Added new function silc_server_command_process_timeout.
1609 * Changed NICK_NOTIFY handling in client library to check that
1610 if the client's nickname was changed, so there is no need to
1611 resolve anything from the server.
1613 * Removed error printing from the WHOIS and IDENTIFY commands.
1614 If error occurs then it is ignored silently in the client library.
1615 The application, however, may map the received error to
1616 human readable error string. The application currently maps
1617 the NO_SUCH_NICKNAME error to string.
1619 * Made the command status message public to the application. Moved
1620 them from lib/silcclient/command_reply.c to
1621 lib/silcclient/command_reply.h. The application can map the
1622 received command status to the string with the
1623 silc_client_command_status_message function.
1625 * Added check to the server to check that client's ID is same
1626 as the Source ID in the packet the client sent. They must
1629 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1631 * Added dist-bzip hook to the Makefile.am to make bzip2
1632 compressed distributions.
1634 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1636 * Server now enforces the maximum length for the nickname and
1637 the channel as protocol specification dictates. 128 bytes for
1638 nickname and 256 bytes for channel name.
1640 * Moved the WHOIS printing to the application. The client libary
1641 does not print out the WHOIS information anymore, the application
1642 must do it. Renamed silc_client_command_reply_whois_print to
1643 the silc_client_command_reply_whois_save.
1645 The client's idle time is also sent to the application now, and
1646 the idle is shown on screen.
1648 * Added silc_client_command_reply_identify_save to save the
1649 received IDENTIFY entries.
1651 * Do not check for channel private keys in message sending and
1652 reception if the channel does not have the PRIVKEY mode set.
1653 Affected file lib/silclient/client_channel.c.
1655 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1657 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1658 just surfaced after chaning the JOIN procedure.
1660 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1662 * Added silc_client_get_clients_by_list to get client entries
1663 from Client ID list, that is returned for example by JOIN
1664 and USERS command replies. The application should use this
1665 function for example when JOIN command reply is received to
1666 resolve the clients already on the channel (library does not
1667 do that anymore as USERS command reply is not used in the JOIN
1668 procedure anymore). Affected files lib/silcclient/silcapi.h and
1669 lib/silcclient/idlist.c.
1671 * JOIN command reply and USERS command reply returns now SilcBuffer
1672 pointers instead of unsigned char pointers when returning
1673 the client list and mode list.
1675 * Added <Client ID> argument to the JOIN command reply, mainly
1676 for the server to identify for which client the command was
1677 originally sent. Updated protocol specs accordingly.
1679 * Added SilcDlist private_key pointer to the SilcChannelEntry
1680 in the client to support the channel private keys. Affected
1681 file is lib/silcclient/idlist.h.
1683 * Added SilcChannelPrivateKey argument to the function
1684 silc_client_send_channel_message so that application can choose
1685 to use specific private ke if it wants to. If it is not provided,
1686 the normal channel key is used, unless private keys are set.
1687 In this case the first (key that was added first) is used
1688 as the encryption key.
1690 * Implemented the support for channel private key handling.
1691 Implemented the following functions:
1693 silc_client_add_channel_private_key,
1694 silc_client_del_channel_private_keys,
1695 silc_client_del_channel_private_key,
1696 silc_client_list_channel_private_keys and
1697 silc_client_free_channel_private_keys
1699 Affected file lib/silcclient/client_channel.c.
1701 * Added the support for the private keys in the channel message
1702 sending and encryption and in the message reception and
1703 decryption. Affected funtions are
1704 silc_client_send_channel_message and silc_client_channel_message.
1706 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1708 * Added SKE's key verify callback to the client library's
1709 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1711 * Removed the statement that server (or router) must send USERS
1712 command reply when joining to the channel so that the client
1713 knows who are on the channel. Instead, the client list and
1714 client's mode list is now sent in the JOIN command reply to the
1715 client who joined channel. This is better solution.
1717 * Added function silc_server_get_users_on_channel and function
1718 silc_server_save_users_on_channel to the silcd/server.[ch].
1720 * Removed function silc_server_command_send_users from the
1723 * Do not show topic on the client library anymore. The topic is
1724 sent in the command reply notify to the application and the
1725 application must show the topic now.
1727 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1729 * Added client searching by nickname hash into the IDENTIFY and
1730 WHOIS commands in the server as they were clearly missing from
1731 them. Affected file is silcd/command.c.
1733 * Fixed a bug in private message receiving in the client library.
1734 The remote ID was freed and it wasn't supposed, now it is
1737 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1739 * Minor fix to the channel payload; allocate the data area, as it
1740 needs to be of specific length.
1742 * If the key agreement port is zero then the operating
1743 system will define the bound port. Affected files are
1744 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1746 * Added new function silc_channel_payload_decrypt into the file
1747 lib/silccore/silcchannel.[ch].
1749 * Moved the channel message etc, check from silc_packet_decrypt
1750 to applications. The library calls now a generic
1751 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1752 when the packet is either normal or special. This was done to
1753 allow more wide range of checking that was not allowed when
1754 the code was in library. Now applications can do virtually any
1755 checks to the packet and return to the library the decision how
1756 the packet should be processed. Affected files are
1757 lib/silccore/silcpacket.[ch].
1759 Added silc_server_packet_decrypt_check to the server and
1760 silc_client_packet_decrypt_check to the client library.
1762 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1763 to send with specified source and destination information.
1765 * Channel message delivery between routers was broken after the
1766 channel key distribution was fixed earlier. The channel key
1767 was used be to distributed to other routers as well which is not
1768 allowed by the protocol. Now this is fixed and channel keys
1769 really are cell specific and the channel message delivery between
1770 routers comply with the protocol specification.
1772 * Fixed various commands in server to check also the global list
1773 for the channel entry and not just the local list. The affected
1774 file silcd/command.c.
1776 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1778 * Added assert()s to buffer formatting and unformatting routines
1779 to assert (if --enable-debug) when error occurs. Affected
1780 file: lib/silcutil/silcbuffmt.c.
1782 * Changed to auto-reconnect to check whether the remote host is
1783 router and register the re-connect timeout if it is. It used
1784 to check that whether we are normal server, but router must do
1785 auto-reconnect with another router as well. Affected file
1788 * Removed the [<key len>] option from CMODE command as the cipher
1789 name decides the key length, nowadays. See the defined ciphers
1790 from the protocol specification.
1792 * Added [<hmac>] option to the CMODE command to define the HMAC
1793 for the channel. Added SILC_CMODE_HMAC channel mode.
1795 * Added [<hmac>] option for the JOIN command so that user can
1796 select which HMAC is used to compute the MACs of the channel
1799 * Added Hmac field to the Channel Message Payload. The integrity
1800 of plaintext channel messages are now protected by computing
1801 MAC of the message and attaching the MAC to the payload. The
1802 MAC is encrypted. Now, it is clear that this causes some
1803 overhead to the size of the packet but rationale for this is that
1804 now the receiver can verify whether the channel message decrypted
1805 correctly and also when private keys are set for the channel the
1806 receiver can decrypt the packet with several keys and check from
1807 the MAC which key decrypted the message correctly.
1809 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1810 lib/silccrypt/silccipher.[ch].
1812 * Added silc_hash_len to return the digest length into the
1813 lib/silcrypt/silchash.[ch].
1815 * Rewrote parts of Silc Channel Payload interface in the
1816 lib/silccore/silcchannel.[ch]. The encode function now also
1817 encrypts the packet and parse function decrypts it.
1819 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1821 * Fixed a minor formatting bug in the SKE's key material processing.
1822 It actually might have processed the keys wrong way resulting
1825 * Redefined the mandatory HMAC algorithms and added new algorithms.
1826 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1827 and hmac-md5 truncated to 96 bits. The mandatory is now
1828 hmac-sha1-96. Rest are optional (including the one that used
1829 to be mandatory). Rationale for this is that the truncated HMAC
1830 length is sufficient from security point of view and can actually
1831 make the attack against the HMAC harder. Also, the truncated
1832 HMAC causes less overhead to the packets. See the RFC2104 for
1835 * Added new [hmac] configuration section. The SKE used to use
1836 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1837 is of course wrong. The official names that must be proposed in
1838 the SKE are the ones defined in the protocol specification
1839 (hmac-sha1-96 for example). The user can configure any hmac
1840 using any hash function configured in the [hash] section. At
1841 least, the mandatory must be configured.
1843 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1845 * Added HMAC list to the SKE proposal list. It has now both
1846 hash algorithm list and HMAC list. This makes the protocol
1847 incompatible with previous versions. The SKE now seems to work
1848 the way it is supposed to work, for the first time actually.
1850 * Defined plain Hash algorithms to the protocol specification.
1853 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * Implemented support for key agreement packets into the server.
1856 Added functions silc_server_key_agreement and
1857 silc_server_send_key_agreement. Other than these functions,
1858 server has nothing to do with this packet.
1860 * Added support for private message key packets into the server.
1861 Added functions silc_server_private_message_key and
1862 silc_server_send_private_message_key.
1866 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1867 called in the protocol's final callback instead in the END
1868 protocol state. This makes a little more sense and in the same
1869 time in client we can use the same protocol routines for normal
1870 key exchange and to key agreement packet handling as well.
1872 * Added to both client's and server's KE protocol context the
1873 SilcSKEKeyMaterial pointer to save the key material. We will
1874 bring the key material to the protocol's final callback by doing
1875 this. The final callback must free the key material.
1877 * Added SKE's packet_send callback into client's KE protocol
1878 context so that the caller can choose what packet sending function
1879 is used. This way we can use different packet sending when
1880 doing normal SKE when doing key agreement packet handling (in
1881 the key agreement packet handling we do not want to encrypt
1884 * Implemented the responder side of the key agreement routines
1885 in the client. The client can now bind to specified port and
1886 accept incoming key negotiation. The key material is passed
1887 to the application after the protocol is over.
1889 * Implemented the processing of incoming Key Agreement packet
1890 in the client. Added function silc_client_key_agreement to
1893 * Implemented the intiator side of the key agreement routines
1894 in the client. The client can now initiate key agreement with
1895 another remote client. The key material is passed to the
1896 application after the protocol is over.
1898 * Created client_keyagr.c to include all the key agreement
1901 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1902 SILC_TASK_CALLBACK except that it is not static.
1904 * Created client_notify.c and moved the Notify packet handling
1905 from the client.[ch] into that file.
1907 * Created client_prvmsg.c and moved all private message and
1908 private message key routines from the client.[ch] into that file.
1910 * Create client_channel.c and moved all channel message and
1911 channel private key routines from the client.[ch] into that file.
1913 * Changed silc_client_get_client_by_id_resolve to resolve with
1914 WHOIS command instead of IDENTIFY command, in the file
1915 lib/silclient/idlist.c.
1917 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1919 * Implemented the SKE's responder side to the Client library.
1921 * When FAILURE is received to the protocol do not trust it
1922 blindly. Register a timeout to wait whether the remote closes
1923 the connection as it should do it, only after that process the
1924 actual failure. This was changed to both client and server.
1926 * Added client_internal.h to include some of the structures
1927 there instead of client.h in lib/silcclient/.
1929 * Added function silc_task_unregister_by_callback to unregister
1930 timeouts by the callback function.
1932 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1934 * Some "Incomplete WHOIS info" errors has been appearing on the
1935 log files. Took away the entry->userinfo check from WHOIS
1936 reply sending. The entry->userinfo is now " " if client did not
1937 provide one. I thought this was fixed earlier but something
1938 is wrong still. Let's see if the error still appears.
1940 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1942 * Fixed a minor bug in the login when the channel key is
1943 re-generated in the server. It used to generate the key in
1944 wrong order and thus caused problems in the channel traffic.
1946 * Fixed a minor bug in channel key distsribution after
1947 KICK command. The key was not sent to the router even though
1950 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1952 * Added silc_ske_process_key_material_data as generic routine
1953 to process any key material as the SILC protocol dictates. The
1954 function is used by the actual SKE library but can be used by
1955 applications as well. This relates to the private message keys
1956 and the channel private keys since they must be processed the
1957 same way the normal SILC session keys. The protocol dictates
1958 this. Affected files: lib/silcske/silcske.[ch].
1960 Added also silc_ske_free_key_material to free the
1961 SilcSKEKeyMaterial structure.
1963 * Defined silc_cipher_set_key function to set the key for
1964 cipher without using the object's method function. The affected
1965 files: lib/silccrypt/silccipher.[ch].
1967 * Implemented silc silc_client_add_private_message_key,
1968 silc_client_add_private_message_key_ske,
1969 silc_client_del_private_message_key,
1970 silc_client_list_private_message_keys and
1971 silc_client_free_private_message_keys functions in the
1974 Added functions silc_client_send_private_message_key to send
1975 the Private Message Key payload and silc_client_private_message_key
1976 to handle incoming Private Message Key payload.
1978 * Added Cipher field to the Private Message Key payload to set
1979 the cipher to be used. If ignored, the default cipher defined
1980 in the SILC protocol (aes-256-cbc) is used.
1982 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1984 * Removed lib/silcclient/ops.h file.
1986 Redefined parts of the SILC Client Library API. Created new
1987 file silcapi.h that deprecates the ops.h file and defines the
1988 published Client Library API. Defined also private message key
1989 API and channel private key API into the file.
1991 This is the file that the application must include from the
1992 SILC Client Library. Other files need not be included by
1993 the application anymore.
1995 * Added new key_agreement client operation callback and also
1996 defined the Key Agreement library API for the application.
1998 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2000 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2001 is used by clients to request key negotiation between another
2002 client in the SILC network. If the negotiation is started it
2003 is performed using the SKE protocol. The result of the
2004 negotiation, the secret key material, can be used for example
2005 as private message key.
2007 Implemented the Key Agreement payload into the files
2008 lib/silccore/silauth.[ch].
2010 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2012 * Redefined ciphers for the SILC protocol. Added some new ciphers
2013 and defined the key lengths for the algorithms. Changed the
2014 code accordingly. The default key length is now 256 bits.
2016 * Fixed SKE key distribution function silc_ske_process_key_material
2017 when the key length is more than 128 bits. The default key
2018 length in SILC is now 256 bits.
2020 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2021 to indicate unsupported algorithm.
2023 * Renamed rijndael.c to aes.c and all functions as well.
2025 * Fixed a long standing channel key setting bug in client library.
2026 Weird that it has never surfaced before.
2028 * Fixed bug in channel deletion. If the entire channel is removed
2029 then it must also delete the references of the channel entry
2030 from the client's channel list as the client's channel entry and
2031 the channel's client entry share same memory.
2033 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2035 * Implemented CONNECT and SHUTDOWN commands in the client.
2037 * Implemented CLOSE command to the client.
2039 * Added the function silc_idlist_find_server_by_name into the
2040 files silcd/idlist.[ch].
2042 Added the function silc_idlist_find_server_by_conn into the
2043 files silcd/idlist.[ch].
2045 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2047 * DIE command was renamed to SHUTDOWN. Updated the both code
2050 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2051 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2053 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2056 * Added function silc_server_create_connection function to create
2057 connection to remote router. My server implementation actually
2058 does not allow router to connect to normal server (it expects
2059 that normal server always initiates the connection to the router)
2060 so the CONNECT command is only good for connecting to another
2063 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2065 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2066 or some other client was kicked from the channel.
2068 Implemented the handling of the notify type to both client
2071 Implemented silc_server_send_notify_kicked to send the KICKED
2072 notify. It is used to send it to the server's primary router.
2074 * Implemented the KICK command into server and client.
2076 * Added `query' argument to the silc_idlist_get_client function
2077 to indicate whether to query the client from server or not if
2080 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2081 to indicate that the client is not channel founder.
2085 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2087 * Removed the rng context from SilcPacketContext structure and
2088 changed that the packet routine uses the Global RNG API.
2090 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Added support for quit message that client can "leave" on the
2093 channel when it quits the SILC. It is ditributed inside the
2094 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2096 Added silc_server_free_client_data that will take the
2097 signoff message as argument.
2099 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2101 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Updated parts of the protocol specification to keep it up
2106 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2109 payloads in one packet.
2111 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2112 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2113 use now the new List flag.
2115 * Also deprecated the following packet types: REPLACE_ID,
2116 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2118 * Added list support for Notify packet in server.
2120 * Added silc_server_send_notify_channel_change to send the
2121 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2122 the silc_server_send_replace_id.
2124 * Added silc_server_send_notify_nick_change to send the
2125 NICK_CHANGE notify type. Deprecates the function
2126 silc_server_send_replace_id.
2128 * Added silc_server_send_notify_join to send the JOIN notify type.
2129 Deprecates the function silc_server_send_new_channel_user.
2131 * Added silc_server_send_notify_leave to send LEAVE notify type.
2132 Deprecates the function silc_server_send_remove_channel_user.
2134 * Added silc_server_send_notify_cmode and
2135 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2136 types. Deprecates the silc_server_send_set_mode function.
2138 * Added SERVER_SIGNOFF notify type to indicate that server has
2139 quit. This means that all clients on the channel from that
2140 server will drop. This can be also used when netsplit happens.
2142 Deprecated REMOVE_ID packet type since it is not needed anymore
2145 Added silc_server_send_notify_server_signoff to send the
2146 SERVER_SIGNOFF notify type. Deprecates the function
2147 silc_server_send_remove_id.
2149 Added also silc_server_send_notify_signoff to send the
2150 SIGNOFF notify type.
2152 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2153 SILC protocol from this day on. Changed the protocol
2154 specification as well.
2156 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2157 notify type. It is used between routers to notify about
2158 topic changes on a channel.
2160 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2163 * Partly updated the protocol specification to comply with the
2164 changes now made. It is still though a bit outdated.
2166 * The JOIN notify type now takes one extra argument <Channel ID>.
2167 The packet used to be destined to the channel but now the
2168 JOIN type may be sent as list thus it is impossible to
2169 destine it to any specific channel. By adding this argument
2170 it is again possible.
2172 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2174 * Added CREDITS file. The CHANGES and CREDITS file will appear
2175 in the distribution as well.
2177 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2179 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2180 types in the server's silcd/packet_receive.c.
2182 * Implemented CMODE and CUMODE to work in router environment.
2184 * Fixed minor encoding and decoding buglet from the
2185 lib/silccore/silcmode.c.
2187 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2190 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2192 * Changed all SilcConfigServer* and silc_config_server* to
2193 SilcServerConfig* and silc_server_config*, respectively.
2196 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2198 * Associated the ID (client or server ID) to the Authentication
2199 Payload to avoid any possibility of forging. Updated the
2200 protocol specification and the code accordingly.
2202 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2204 * The RSA key length is now save to the RsaKey context in the
2205 key generation process in lib/silccrypt/rsa.c. The key length
2206 is now used to figure out the maximum size of the block allowed
2207 to be encrypted/signed.
2209 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2210 is equivalent to the silc_mp_mp2bin but does not allocate any
2213 * Changed silc_mp_mp2bin API to take length argument. If it is
2214 non-zero then the buffer is allocated that large. If zero, then
2215 the size is approximated using silc_mp_sizeinbase, which however
2218 * Created Global RNG API which is global RNG that application can
2219 initialize. After initializing, any routine anywhere in the
2220 code (including library) can use RNG without allocating a new
2221 RNG object. This was done to allow this sort of use of the
2222 RNG in code that has no chance to allocate RNG object. All
2223 applications currently allocate this and many routines in the
2224 library use this. Affected file lib/silccrypt/silcrng.[ch].
2226 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2227 it to use the Global RNG API.
2229 * Defined Authentication Payload into protocol specification that
2230 is used during SILC session to authenticate entities. It is
2231 used for example by client to authenticate itself to the server
2232 to obtain server operator privileges.
2234 Implemented this payload into the lib/silccore/silcauth.[ch].
2235 Implemented also routines for public key based authentication
2236 as the new protocol specification dictates.
2238 Moved definitions of different authentication methods from
2239 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2241 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2242 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2243 silc_pkcs_verify_with_hash functions into the file
2244 lib/silccrypt/silcpkcs.[ch].
2246 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2248 * The client entry's userinfo pointer must be always valid.
2249 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2250 will fail since it requires the userinfo. Now, the userinfo
2251 is allocated as "" if actual userinfo does not exist. Actually,
2252 it must exist and it is totally Ok to drop client connections
2253 that does not announce the userinfo. However, we will make
2254 this workaround for now.
2256 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2257 to return the remote port by socket.
2259 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2262 SILC_SERVER_PENDING_EXEC and added an new macro
2263 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2264 data or when error occurs while processing the pending command.
2266 Added new argument `destructor' into silc_server_command_pending
2267 and to the SilcServerCommandPending object. This destructor is
2268 now called after calling the pending callback or if error occurs
2269 immediately. If error occurs the actual pending callback won't
2270 be called at all - only the destructor. The destructor may be
2271 NULL if destructor is not needed.
2273 All this applies for client library code as well. Similar
2274 changes were made there as well for the pending commands.
2276 In the client, the application must now allocate the
2277 SilcClientCommandContext with the silc_client_command_alloc
2280 * Added reference counter to the SilcServerCommandContext. Added
2281 function silc_server_command_alloc and silc_server_command_dup
2284 Same type of functions added to the client library for the same
2287 * Removed the cmd_ident from IDListData away since it is now
2288 global for all connections. It is the command identifier used
2289 in command sending and with pending commands. The affected file
2292 * Added reference counter to the SilcSocketConnection objecet to
2293 indicate the usage count of the object. The object won't be
2294 freed untill the reference counter hits zero. Currently only
2295 server uses this, and client ignores it. The client must be
2296 set to use this too later. The affected files are
2297 lib/silccore/silcsockconn.[ch]. Added also the function
2298 silc_socket_dup to increase the reference counter.
2300 This was mainly added because it is possible that the socket
2301 is removed underneath of pending command or other async
2302 operation. Now it won't be free'd and proper DISCONNECTING
2303 flags, etc. can be set to avoid sending data to connection that
2304 is not valid anymore.
2306 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2307 the connection. After that it sets SILC_SET_DISCONNECTED.
2308 It is, however, possible that the socket data is not still freed.
2309 The silc_server_packet_process now checks that data is not
2310 read or written to connection that is DISCONNECTED. The socket
2311 get's freed when the reference counter hits zero.
2313 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2315 * Changed the client operation API: channel_message operation's
2316 `sender' is now the client entry of the sender, not the nickname
2317 and the `channel' is the channel entry, not the channel name.
2319 In the private_message operation the `sender' is now also the
2320 client entry of the sender not the nickname.
2322 Affected file is lib/silcclient/ops.h and all applications
2323 using the client operations.
2325 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2327 * Moved the calling of ops->connect() from connect_to_server_final
2328 into receive_new_id functin since that is the point when the
2329 client is actually allowed to send traffic to network. The
2330 affected file is lib/silcclient/client.c.
2332 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2334 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2335 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2336 (if needs broadcasting) instead of broadcasting the packets one
2337 by one which would make a burst in the network traffic.
2339 * Added `broadcast' argument to the functions in silcd/server.[ch]
2340 silc_server_create_new_channel[_with_id] to indicate whether
2341 to send New Channel packet to primary router.
2343 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Added new function into the silcd/server.[ch] files:
2346 silc_server_create_new_channel_with_id to create new channel with
2347 already existing Channel ID.
2349 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2350 lib/silccore/silcpacket.h. This packet is used t send list of
2351 Set Mode payloads inside one packet. Server uses this to set
2352 the modes for the channels and clients on those channels, that it
2353 announced to the router when it connected to it. The protocol
2354 specification has been updated accordingly.
2356 * The silc_server_new_channel did not handle the packet coming
2357 from normal server as it normally does not send that. However,
2358 when it announces its channels it does send it. Implemented
2359 the support for that.
2361 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2362 into the file lib/silccore/id.h.
2364 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2366 * Fixed memory leaks in the functions silc_idlist_del_client,
2367 silc_idlist_del_channel and silc_idlist_del_server in the file
2368 silcd/idlist.c. All of those leaked like a sieve.
2370 * Fixed some small memory leaks in the client's function
2371 silc_client_notify_by_server.
2373 * Added functions into silcd/server.c: silc_server_announce_clients,
2374 silc_server_announce_channels and silc_server_announce_server.
2375 These functions are used by normal and router server to announce
2376 to its primary router about clients, channels and servers (when
2377 router) that we own. This is done after we've connected to the
2380 These functions effectively implements the following packet types:
2381 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2382 and SILC_PACKET_NEW_ID_LIST.
2384 * Added new functions into the silcd/packet_receive.[ch]:
2385 silc_server_new_id_list, silc_server_new_channel_list and
2386 silc_server_new_channel_user_list to handle the incoming
2387 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2389 * Added support of changing Channel ID in the function
2390 silc_server_replace_id. If the server that announces a channel
2391 to the router already exists in the router (with same name but
2392 with different Channel ID), router is responsible to send
2393 Replace ID packet to the server and force the server to change
2394 the Channel ID to the one router has.
2396 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2397 client that the Channel ID has been changed by the router. The
2398 normal server sends this to the client. Client must start using
2399 the new Channel ID as the channel's ID.
2401 Implemented handling of this new type into lib/silcclient/client.c
2402 into the function silc_client_notify_by_server.
2404 * Added new function silc_idlist_replace_channel_id into the files
2405 silcd/idlist.[ch] to replace the Channel ID.
2407 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2409 * Call silc_server_command_identify_check always when processing
2410 the IDENTIFY command in silcd/command.c
2412 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2414 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2415 send keepalive packets. The packet can be sent by clients,
2416 servers and routers.
2418 Added function silc_socket_set_heartbeat into the file
2419 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2420 If not set, the heartbeat is not performed. The actual
2421 heartbeat is implemented in the low level socket connection
2422 library. However, application is responsible of actually
2425 Added silc_server_send_heartbeat to send the actual heartbeat
2426 packet into silcd/packet_send.[ch]. Server now performs
2427 keepalive with all connections.
2429 * Added silc_task_get_first function into lib/silcutil/silctask.c
2430 to return the timeout task with shortest timeout. There was a bug
2431 in task unregistration that caused problems. TODO has been
2432 updated to include that task system must be rewritten.
2434 * The client library will now resolve the client information when
2435 receiving JOIN notify from server for client that we know but
2436 have incomplete information.
2438 * Rewrote parts of silc_server_remove_from_channels and
2439 silc_server_remove_from_one_channel as they did not remove the
2440 channel in some circumstances even though they should've.
2442 * Encryption problem encountered in server:
2444 The LEAVE command used to send the Channel Key packet to the
2445 router immediately after generating it. However, the code
2446 had earlier sent Remove Channel user packet but not immediately,
2447 ie. it was put to queue. The order of packets in the router
2448 was that Channel Key packet was first and Remove Channel User
2449 packet was second, even though they were encrypted in the
2450 reverse order. For this reason, MAC check failed. Now, this
2451 is fixed by not sending the Channel Key packet immediately but
2452 putting it to queue. However, this is more fundamental problem:
2453 packets that are in queue should actually not be encrypted
2454 because packets that are sent immediately gets encrypted
2455 actually with wrong IV (and thus MAC check fails). So, packets
2456 that are in queue should be encrypted when they are sent to
2457 the wire and not when they put to the queue.
2459 However, the problem is that the current system has not been
2460 designed to work that way. Instead, the packet is encrypted
2461 as soon as possible and left to the queue. The queue is then
2462 just purged into wire. There won't be any fixes for this
2463 any time soon. So, the current semantic for packet sending
2466 o If you send packet to remote host and do not force the send
2467 (the packet will be in queue) then all subsequent packets to the
2468 same remote host must also be put to the queue. Only after the
2469 queue has been purged is it safe again to force the packet
2472 o If you send all packets immediately then it safe to send
2473 any of subsequent packets through the queue, however, after
2474 the first packet is put to queue then any subsequent packets
2475 must also be put to the queue.
2477 Follow these rules and everything works fine.
2479 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2481 * Added new function silc_server_remove_clients_by_server to
2482 remove all client entries from ID list when the server connection
2483 is lost. In this case it is also important to invalidate all
2484 client entires as they hold the invalid server entry. This
2485 fixes fatal bug when server has lost connection and will reconnect
2488 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Made some sanity checks to silc_server_daemonise like to check
2491 whether the requested user and group actually exists.
2493 * Added sanity check to SKE's silc_ske_responder_finish to check
2494 that the public and private key actually is valid.
2496 * Invalidate the client's nickname when receiving Replace ID
2497 packet and the Client ID is being replaced. This means that the
2498 server will query the nickname if someone needs it (client)
2501 * Sort the ID Cache in client library when the ID Cache data
2502 has changed (needs sorting).
2504 * Do not allow for SILC client to create several connections to
2505 several servers. The client does not support windows right now
2506 and generating multiple connections causes weird behaviour.
2508 Irssi-silc client does support windows and can handle several
2509 connections without problems, see: www.irssi.org and SILC plugin.
2511 * Fixed some places where client was added to the IDList. The
2512 rule of thumb is following (in order to get everything right):
2513 If the client is directly connected local client then the
2514 `connection' argument must be set and `router' argument must be
2515 NULL to silc_idlist_add_client function. If the client is not
2516 directly connected client then the `router' argument must
2517 bet set and the `connection' argument must be NULL to the
2518 silc_idlist_add_client function.
2520 * The funtion silc_server_packet_send_local_channel actually did
2521 not check whether the client was locally connected or not. It
2522 does that now. Fixed a bug related to LEAVE command.
2524 * Fixed Remove Channel User payload parsing bug in server's
2525 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2527 * The server's silc_server_save_channel_key now checks also the
2528 global ID list for the channel as it might not be in the local
2529 list. Fixed a bug related to LEAVE command.
2531 * Is this the end of the [<unknown>] buglet that has been lurking
2532 around for a long time? A little for loop fix in server's
2533 silc_server_command_whois_parse that is used by both IDENTIFY
2534 and WHOIS command. At least, this was a clear bug and a cause
2535 of one type of [<unknown>] buglet.
2537 * WHOIS and IDENTIFY commands call the function
2538 silc_server_command_[whois/identify]_check function even if
2539 we are not router server.
2541 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2543 * Added --with-gmp configuration option. If set the GMP
2544 is always compiled in the SILC source tree. If not set then
2545 it is checked whether the system has the GMP3 installed. If
2546 it has then the GMP won't be compiled (the system's headers
2547 and library is used), if it doesn't have it then the GMP is
2548 compiled in the SILC source tree.
2550 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Changed RSA private exponent generation to what PKCS #1
2553 suggests. We try to find the smallest possible d by doing
2554 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2555 not security fix but optimization.
2557 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2559 * Added new config entry [Identity] to fork the server and run
2560 it as specific user and group. A patch from Bostik.
2562 * Imported Dotconf configuration library into lib/dotconf.
2563 This will be used to create the SILC configuration files later.
2564 It will appear in the distsribution after this commit.
2566 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2568 * A big code auditing weekend happening. Auditing code for
2569 obvious mistakes, bugs and errors. Also, removing any code
2572 Removed files for being obsolete:
2574 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2575 inline in the file lib/silcutil/silcbuffer.h)
2577 o lib/silcutil/silcbufutil.c (the header has inline versions)
2579 Changed code to fix possible error conditions:
2581 o The buffer formatting routines now check that the destination
2582 buffer really has enough space to add the data. This applies for
2583 both buffer formatting and unformatting
2584 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2585 unformatting was changed to accomodate following rules:
2586 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2587 sent to the function while XXX_*STRING will not allocate or copy
2588 the data into the buffer. Instead it sets the pointer from the
2589 buffer into the pointer sent as argument (XXX_*STRING used to
2590 require that the pointer must be allocated already). This change
2591 makes this whole thing a bit more consistent and more optimized
2592 (note that the data returned in the unformatting with XXX_*STRING
2593 must not be freed now). The routines return now -1 on error.
2595 o Tried to find all code that use buffer_format and buffer_unformat
2596 and added return value checking to prevent formatting and
2597 especially unformatting errors and possible subsequent fatal
2600 o Changed ske->x and ske->KEY to mallocated pointers in
2601 lib/silcske/silcske.h. Fixed possible data and memory leak.
2603 o Added return value checking to all *_parse* functions. Fixed
2604 many memory leaks as well.
2606 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2607 so that buffer overflows would not happen. All code now also
2608 checks the return value as it can fail.
2610 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Added reconnection support to server if the normal server looses
2613 its connection to the router (for example if router is rebooted).
2614 The server performs normal reconnection strategy implemented
2615 to the server. Affected file silcd/server.c.
2617 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2619 * Added new packet type SILC_PACKET_SET_MODE that is used to
2620 distribute the information about changed modes (for clients,
2621 channels and clients channel modes) to all routers in the
2622 network. Updated the protocol specification accordingly.
2624 Added functions into silcd/packet_send.c and
2625 silcd/packet_receive.c: silc_server_send_set_mode,
2626 silc_server_set_mode.
2628 Added new files silcmode.[ch] into lib/silccore that implements
2629 the encoding and decoding of Set Mode Payload. Added new type
2630 SilcSetModePayload. Moved the definitions of different modes
2631 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2633 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2635 * Oops, a little mistake in server's connection authentication
2636 protocol. The protocol is not ended with FAILURE but with
2637 SUCCESS if the authentication is Ok. :) Affected file is
2640 * Implemented NICK_CHANGE notify handling in server in the file
2641 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2642 the local clients on the channel. After the changing nickname
2643 in router environment snhould work and the [<unknown>] nickname
2644 should appear no more.
2646 The silc_server_replace_id function that receives the Replace ID
2647 payload now sends the NICK_CHANGE notify type also in the file
2648 silcd/packet_receive.c
2650 * Changed WHOIS and IDENTIFY command to support the maximum amount
2651 of arguments defined in protocol specs (3328 arguments). This
2652 fixed a bug that caused problems when there were more than three
2655 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Added extra parameter, command identifier, to the
2658 silc_client_send_command so that explicit command identifier
2661 Changed that ID list routines uses specific command identifier
2662 when sending WHOIS/IDENTIFY requests to the server so that they
2663 can be identified when the reply comes back.
2665 Affected files lib/silcclient/command.[ch],
2666 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2668 * Added `sender' argument to silc_server_packet_send_to_channel
2669 to indicaet the sender who originally sent the packet to us
2670 that we are now re-sending. Ignored if NULL. Affected file
2671 silcd/packet_send.[ch].
2673 * Added some server statistics support in silcd/server_internal.h
2674 SilcServerStatistics structure and around the server code. Also
2675 send some nice statistics information when client is connecting
2678 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2680 * Fixed channel ID decoding in server's JOIN command reply in
2681 silcd/command_reply.c
2683 * Fixed braodcasting of replace ID payload to not to send it if
2684 we are standalone server in silcd/packet_receive.c.
2686 * Fixed all channel message sending routines to not to send
2687 packets to clients that has router set, since they are routed
2688 separately in the same function earlier. Affects file
2689 silcd/packet_send.c and all channel packet sending functions.
2691 * In USERS reply, res_argv[i] are not allocated, the table
2692 is allocated. Thus changed that free the table, not its
2695 * In server's whois_check and identify_check if the client is
2696 locally connected do not send any WHOIS commands - they are not
2699 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2701 * Fixed some minor bugs in client when sending WHOIS command. The
2702 arguments was in wrong order.
2704 * Removed statis function add_to_channel from server in
2705 silcd/command.c that was previously used with the joining but
2708 * Tested USERS command in router environment successfully with two
2709 routers, two servers and two clients.
2711 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2713 * Reorganized the USERS command and command reply in client library
2714 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2715 When the command is given by user we register a pending command
2716 callback that will reprocess the command after the reply has been
2717 received from the server. When reprocessing the packet we then
2718 display the information. Thus, the USERS information is displayed
2719 now in the command callback instead of in the command reply
2720 callback. The processing of the command is same as previously
2721 when server has sent the command reply in the JOINing process.
2723 * Added to USERS command in silcd/command_reply.c to join the client,
2724 we didn't use to know about, to the channel after we've created
2725 a client entry for it. Also, for clienet we did know already still
2726 check whether it is on the channel or not and add it if not.
2728 * Removed silc_server_command_join_notify as the function and its
2731 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2733 * Changed the client's pending command handling to the same as the
2734 server's pending command handling. It is also now possible to
2735 execute command reply functions from other command reply
2736 function as the function callbacks for commands and command
2737 replies are one and same. The pending commands are not static
2738 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2739 in client connection context. Thus, pending commands are server
2740 connection specific as it is convenient.
2742 Changed the function silc_client_command_pending and
2743 silc_client_command_pending_del and added new function
2744 silc_client_command_pending_check. Removed the
2745 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2748 * Added cmd_ident, current command identifier, to the client
2749 connection context in lib/silcclient/client.h to keep track on
2750 command identifiers used in command sending. Client's command reply
2751 function handling now supports the mandatory command identifiers.
2753 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2754 funtions in client to fully support pending command callbacks.
2756 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2757 as one of the arguments to the application in the command reply
2760 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2761 before first releasing SILC but came back. Now it is removed again
2762 and should come back nomore. The FORWARDED flag was used only
2763 by the JOINing procedure by forwarding the command packet to router.
2764 Now, the JOINing procedure has been changed to more generic (due
2765 to various router environment issues) and FORWARDED is not needed
2766 anymore for anything. The protocol specification is yet to be
2769 Now, removed silc_server_packet_forward from server and the flag
2770 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2772 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2774 * Renamed NAMES command to USERS command. The NAMES was named that
2775 due to historical reasons. Now it is renamed. Also, rewrote
2776 parts of the USERS command. The nickname list is not sent anymore
2777 by the server. Only Client ID and mode lists are sent in the USERS
2778 command. Changed this also to the protocol specification.
2780 The client now resolves the names and stuff after it receives
2781 the USERS list from the server when joining to the channel.
2783 * WHOIS and IDENTIFY commands has been changed to support multiple
2784 Client ID's per command. One can now search for multiple users
2785 in the network by sending only one WHOIS or IDENTIFY command.
2786 Changed the code and the protocol specifications.
2788 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2789 uses silc_server_command_whois_parse to parse the request. */
2791 * If normal server, do not parse the WHOIS and IDENTIFY requests
2792 before sending it to the router. Saves some time.
2794 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2796 * Fixed JOIN command on client library. Wrong number of arguments
2797 used to crash the client.
2799 * Added silc_server_channel_has_global function to check whether
2800 channel has global users or not.
2802 * Added silc_server_channel_has_local function to check whether channel
2803 has locally connected clients on the channel.
2805 * The silc_server_remove_from_one_channel now checks whether the
2806 channel has global users or not after given client was removed from
2807 the channel. It also checks whether the channel has local clients
2808 on the channel anymore. If it does not have then the channel entry
2809 is removed as it is not needed anymore.
2811 * The silc_server_notify now checks on JOIN notify whether the joining
2812 client is one of locally connected or global. If it is global then
2813 the channel has now global users on the channel and that is marked
2814 to the channel entry. Also, it now saves the global client to
2815 global list who is joining and JOINs it to the channel. This is
2816 for normal server, that is.
2818 Changed silc_server_send_notify_on_channel,
2819 silc_server_packet_relay_to_channel and
2820 silc_server_packet_send_to_channel check if we are normal server
2821 and client has router set (ie. global client) do not send the
2822 message to that client, as it is already routed to our router.
2824 * Implemented LEAVE notify type handling in silc_server_notify
2827 * Tested LEAVE command in router environment successfully. Tested
2828 with two routers, two servers and two clients.
2832 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2834 * Implemented SIGNOFF notify type handling in silc_server_notify
2837 * silc_server_remove_id now removes the client entry from all channels
2838 it has joined and thusly sends SIGNOFF notify type.
2840 * Rewrote the NAMES list generation in server by removing two excess
2841 loops. The lists are created now inside one loop.
2843 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2845 * silc_server_remove_channel_user checks now also global list
2846 for channel and client.
2848 * silc_server_new_channel_user checks now both local and global
2849 list for channel and client. Fixed a bug in client id decoding.
2850 Used to decode wrong buffer.
2852 * silc_server_channel_message checks now both local and global
2853 list for channel entry.
2855 * Tested channel joining (hence JOIN) in router environment
2856 successfully. Tested with two routers, two servers and two
2859 * Tested channel message sending in router environment successfully.
2861 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2863 * Added silc_server_save_channel_key into server.[ch] to save the
2864 received channel key in Channel Key payload processing. It is
2865 also used in JOIN command reply handling.
2867 Equivalent function silc_client_save_channel_key added into
2868 client.[ch] into client library.
2870 * Changed JOIN command reply to send information whether the channel
2871 was created or not (is existing already) and the channel key
2872 payload. Changed protocol specs accordingly.
2874 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2875 the request was sent by ID and not by nickname. Crashed on
2878 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2880 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2881 now correctly save the received data.
2883 * silc_server_free_sock_user_data now notifies routers in the
2884 network about entities leaving the network.
2886 At the same time implemented functions silc_server_remove_id
2887 and silc_server_send_remove_id to receive and send REMOVE_ID
2888 packets. The packet is used to notify routers in the network
2889 about leaving entities. The ID removed will become invalid in
2892 * Added function silc_idlist_del_server into server. Removes and
2893 free's server entry from ID list.
2895 * silc_server_private_message function now checks, if we are router,
2896 that the destination ID really is valid ID, naturally.
2898 * In router when NEW_ID packet is received (for new client) the
2899 hash of the Client ID is saved in the ID Cache but the
2900 client->nickname is set to NULL, instead of putting the hash
2903 IDENTIFY command now also checks that client->nickname must be
2904 valid. If it is not if will request the data from the server who
2905 owns the client. Added new function
2906 silc_server_command_identify_check.
2908 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2909 to set the command to already allocated Command Payload.
2911 * Tested private message sending in router environment with two
2912 routers, two servers and two clients. Fixed minor bugs and now
2915 * Fixed segfault from client's NAMES command. Used to crash if
2918 * Forwarded packets must not be routed even if it is not destined
2919 to the receiver. Changed server code comply with this.
2921 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2923 * Added `require_reverse_mapping' boolean value to ServerParams
2924 structure. If TRUE (not default) the server will require that
2925 the connecting host has fully qualified domain name.
2927 If the reverse mapping is not required and hostname could not be
2928 found the IP address is used as hostname.
2930 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2932 * Implemented version string checking to both client and server.
2933 The check is incomplete currently due to the abnormal version
2934 strings used in development version of SILC.
2936 * Changed all command functions in server to use the new
2939 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Changed char *data to unsigned char *data in ID Cache system to
2942 support binary data as ID Cache data. Changed code to support
2943 binary data in lib/silccore/idcache.c.
2945 * Renamed silc_server_packet_relay_command_reply to
2946 silc_server_command_reply as it is normal packet receiving
2947 function. Rewrote the function to accept command replys for
2948 servers and not only for clients.
2950 * Mark remote router always as registered server if we are connecting
2951 to it. Otherwise, commands sent by the router to us are ignored.
2953 * All ID List find routines now returns the ID Cache Entry pointer
2954 as well if requested.
2956 * WHOIS command works now in router environment, tested with two
2957 routers, two servers and two clients.
2959 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2960 in router environment (as it is almost equivalent to WHOIS) but
2961 hasn't been tested thoroughly. Added new functions:
2963 silc_server_command_identify_parse
2964 silc_server_command_identify_send_reply
2965 silc_server_command_identify_from_client
2966 silc_server_command_identify_from_server
2968 * Disabled route cache adding because adding two different ID's with
2969 same IP replaces the old cache entry thus giving wrong route.
2970 The entry->router->connection is always the fastest route anyway
2971 so route cache may not be needed. Of course, new routes maybe
2972 established after receiving the ID when the entry->router->connection
2973 might not be anymore the most optimal.
2975 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Add route cache for received ID for fast routing.
2979 * Added silc_server_packet_route to route received packet on router
2980 that is not destined to us.
2982 * Renamed silc_server_get_route to silc_server_route_get.
2984 * Added id_string and id_string_len fields into SilcServer to
2985 include encoded ServerID for fast comparing without excess
2986 encoding of the ID's.
2988 * Cleaned up WHOIS command on server side. Added following static
2991 silc_server_command_whois_parse
2992 silc_server_command_whois_check
2993 silc_server_command_whois_send_reply
2994 silc_server_command_whois_from_client
2995 silc_server_command_whois_from_server
2997 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2998 arguments in command replies. All command functions should be
2999 updated to use this macro.
3001 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3003 * Minor typo fixes on command reply handling on server.
3005 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Added silc_server_command_add_to_channel internal routine to add
3008 the client to the channel after router has created the channel and
3009 sent command reply to the server.
3011 * Added generic silc_server_send_command to send any command from
3014 * Use static buffer with ID rendering instead of duplicating data.
3016 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Fixed a channel user mode bug when joining to a channel server gave
3019 everybody channel founder rights, oops.
3021 * We mark ourselves as the router of the incoming server connection
3022 if we are router ourselves. This way we can check in some packet
3023 sending functions whether it is locally connected server. For
3024 incoming router connections we put NULL.
3026 * For router sending packets locally means now always sending the
3027 packet cell wide; to local clients and local servers. For normal
3028 server sending packet locally means sending it to only local
3031 * Fixed the JOIN command to really work in router environment. If the
3032 channel is created it is always created by the router. Router is
3033 also responsible of making the initial joining to the channel,
3034 sending JOIN notify to the sending server and distributing
3035 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3036 does not exist server doesn't do anything else but forward the
3037 command to the router which performs everything.
3039 * Added silc_server_send_channel_key function to send the Channel Key
3042 * Added silc_server_create_channel_key to create new channel key. The
3043 channel key is now re-generated everytime someone joins or leaves
3044 a channel, as protocol dictates. Note: channel->key_len is the
3047 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3050 packet_receive.[ch] to separate packet sending and receiving
3051 routines. The server.[ch] now includes everything else including
3052 actual packet processing (writing and reading data) and other
3055 Renamed silc_server_private_message_send_internal to
3056 silc_server_send_private_message. The routine is still though
3057 used only to relay private messages as server does not send
3058 private messages itself.
3060 Renamed silc_server_new_channel to silc_server_create_new_channel
3061 and added new function sicl_server_new_channel that handles the
3062 incoming New Channel packet. Added also new sending function
3063 silc_server_send_new_channel to send New Channel Payload.
3065 * Added new function silc_server_notify to process incoming notify
3066 packet to the server/router. Server may then relay the notify
3067 to clients if needed.
3069 * Added new function silc_server_new_channel_user to process incoming
3070 New Channel User packet. Router will redistribute the packet and
3071 send JOIN notify to its local clients and locally connected servers
3072 if needed. Normal server will send JOIN notify to its local client
3073 on same channel when received this packet. Added also corresponding
3074 sending function silc_server_send_new_channel_user to sent the
3077 * Added boolean route argument to send_notif_to_channel and
3078 packet_send_to_channel functions to attempt to route the packet
3079 if it is TRUE and send only locally if it is FALSE.
3081 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * silc_server_replace_id now broadcasts the received replace ID
3084 packet if it is not broadcast packet already. The router must
3085 broadcast to inform other routers about changed ID.
3087 * Added backpointer to server's router into SilcServer context in
3088 silcd/server_internal.h.
3090 * Fixed silc_server_packet_broadcast to send correct broadcast
3093 * The channel key is now distributed to the local client as soon
3094 as it is received from the router (in router environment) so that
3095 no other packet may be sent for the channel until client has
3098 * silc_server_remove_channel_user now broadcasts the received
3099 Remove Channel User packet if it is not broadcast packet already.
3100 The router must broadcast to inform other routers about removed
3103 * Added users field into SilcPacketContext that is a reference count
3104 of the context. One can increase the reference count by calling
3105 silc_packet_context_dup which is now changed to just increase the
3106 reference count instead of duplicating the data. The reference
3107 count is decresed by calling silc_packet_context_free that will
3108 free the data after the reference count hits zero.
3110 For now on the packet context and everything allocated into it
3111 (including the raw packet from network) must be freed by calling
3112 the new silc_packet_context_free function. Added also new function
3113 silc_packet_context_alloc that must be used now to allocate the
3114 context. This also means that if a routine is asynchronous from
3115 silc_[client/server]_packet_parse_type the packet context must
3116 be duplicated by calling silc_packet_context_dup. Otherwise it
3117 gets free'd after silc_[client/server]_packet_parse_type returns.
3118 Also, one must remember that if packet is duplicated then its
3119 reference count must be decresed by calling the free function as
3120 many times as it was duplicated.
3122 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3123 from both client and server.
3125 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3127 * Made joining to a channel working in router environment.
3129 * Cleaned up JOIN command on server side and create function
3130 silc_server_command_join_channel internal routine to make the
3133 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3135 * Changed silc_command_pending list to SilcDList. Also, added
3136 `ident' field to SilcServerCommandPending structure to identify
3137 the reply and to call correct callback.
3139 Added silc_server_command_pending_check function to replace the
3140 corresnponding macro. The silc_command_pending list is not
3143 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3144 to set identifier to previously allocated Command Payload. It
3145 is used to set identifier for command when resending Command
3148 * Added silc_command_payload_encode_payload to encode Command
3149 Payload buffer from SilcCommandPayload structure.
3151 * Added silc_argument_payload_encode_payload to encode Argument
3152 payload buffer from SilcArgumentPayload structure.
3154 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Changed WHOIS command to support router connection on server side.
3157 The whois request is always sent to router unless the server is
3158 standalone server. After server has received the reply from the
3159 router will it send the reply to the client.
3161 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3162 broadcast received broadcast packet. The function is used only
3163 by router. The broadcast packet is always sent to the router's
3166 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3167 render given ID to printable string, for log files for example.
3169 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Made basic router to router connections working. At least they
3172 can now connect to each other but nothing really works the way
3173 they are supposed - yet.
3175 * Added new initiator token to RouterConnection configuration
3176 file in silcd/serverconfig.[ch]. It is used to tell whether we
3177 are the initiator to the remote router or whether we'll expect
3178 the other end to connect.
3180 * Moved registering of listener task to silc_server_init, hence
3181 the server starts listenning as soon as it is run, even if it
3182 does not have connections to other routers. Let's see how well
3185 * Changed default connection retry timeouts for more suitable in
3188 * Removed cipher and such arguments from silc_idlist_add_client
3189 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3190 Added new function silc_idlist_add_data to add the keys and stuff
3193 * Added SilcIDListData structure and added it to SilcClientEntry
3194 and SilcServerEntry as their first field in the structure. This
3195 way we can explicitly cast the ID entries to the SilcIDListData
3196 structure and get common data for the entries. In past, we had
3197 to first check what type of connection it is and then cast it to
3198 correct ID entry type. Now, we can directly cast the opaque
3199 pointer to the SilcIDListData (no matter what ID entry it actually
3200 is) and get the data needed.
3202 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3204 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3205 in some circumstances even if threre were timeout tasks, though not
3206 IO tasks, but tasks anyway. Now fixed.
3208 * Defined SilcServerConnection structure to hold connection specific
3209 stuff about directly connected servers and routers. The definition
3210 is currently in silcd/server_internal.h. I thought about having
3211 a bit more important role fro this struct but for now it is used
3212 only when connecting to other server (or router actually).
3214 * Added connecting retry support in server when connecting to
3215 router(s). The retry feature implement exponential backoff
3216 algorithm. Also, added SilcServerParams structure to hold default
3217 parameters for server. For now, it include these retry settings
3218 and are hard coded. After server is moded to be as Silc Server
3219 Library this structure will be more important.
3221 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3223 * Changed client librarys channel->clients table to SilcList and
3224 changed code accordingly.
3226 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Changed client's channel table to SilcList and changed code
3229 accordingly. Also changed SilcChannelClientEntry to include back-
3230 pointer to the channel so that client entry can use that structure
3231 as list as well and we have fast cross-reference to the channel.
3232 This change dramatically decreased the complexity of channel
3233 handling with client entry and vice versa (removed one extra
3234 loop when searching for channel entry from many functions).
3236 * Changed server->sim from table to SilcDList and changed code
3239 * NAMES command can now be used from user interface. It will show
3240 the user list on the channel, neatly.
3242 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3243 Code now saves realname of the user if it becomes available.
3245 * Renamed configure.in to configure.in.pre and made ./prepare
3246 script to automatically add correct version string to
3247 configure.in which it creates from configure.in.pre.
3249 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3251 * NAMES command reply now shows users mode with the nickname when
3254 * Moved silc_client_ch[u]mode[_char] functions from
3255 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3256 place sucks, they are utility functions and should be in some
3259 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3261 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3264 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Added TRQ (efficient deque and list library) into lib/trq. This is
3269 a very good list library that is currently used in the SILC. Defined
3270 SilcList API over the library because I didn't like the API very
3271 much. See lib/trq/silclist.h for the API and examples of how to
3272 use the API. Fixed various places in the code to use the new
3273 SilcList API. The SilcList is meant for lists that has a structure
3274 already defined as a list. It is not suitable to add just some
3275 context to the list (in TRQ, the context is the list actually).
3277 So, I defined SilcDList that can be used for the purpose where
3278 predefined list structure does not exit. This can be used as
3279 such list. Now some context just can be added to the SilcDList.
3280 Currently this list is not used in the SILC just yet, though there
3281 are a lot places where this can replace dynamically allocated
3282 tables and I will fix these places, later, to use SilcDList.
3283 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3284 and use TRQ internally).
3286 Also fixed some annoying warning messages that the original TRQ
3287 code generated. Also minor changes to TRQ's Makefile.in.
3289 * Added support for querying by Client ID to both WHOIS and
3290 IDENTIFY commands into server, as required by the protocol.
3292 * Removed method function pointers from SilcBuffer structure. They
3293 weren't used to anything and just increased the context size for
3294 no good reason. This change also made silc_buffer_alloc and
3295 silc_buffer_free functions inline functions.
3297 * Disabled command flooding detection support until it's fixed so
3298 that it accepts commands in but does not execute them more than once
3301 * Added silc_net_localhost(), to return local hostname, into
3302 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3303 that must be initialized before calling silc_client_init.
3305 * Added new function: silc_server_send_notify_on_channels to send
3306 notify messages to all channels client has joined. It is assured
3307 that the message is sent only once per client.
3309 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3310 lib/silcutil/silcutil.[ch] as silc_format function. The new
3311 function is generic and is used by server as well, not only by
3312 the logging routines.
3314 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3315 the provided version string was not acceptable. Added new function:
3316 silc_ske_check_version into lib/silcske/silcske.h. The function
3317 must be implemented by the application (client or server) and it
3318 does not reside in the SKE library. The function checks the version
3319 string remote end sent.
3321 * Added back pointers (to opaque context and to SilcSocketConnection)
3322 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3324 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3325 duplicate packet context structure.
3327 * Changed `notify' client operation to send same arguments as client
3328 receives from server except for ID's. ID's are mapped to correct
3329 ID entry and that is returned. Also, if channel entry is not sent
3330 by server but the notify is for channel the channel entry is sent
3331 to application (otherwise application doesn't know that it is for
3332 channel (library gets it from packet's Destination ID)).
3334 * Added silc_client_remove_from_channels into client library to
3335 remove a client from all channels it has joined to. Used when
3336 received SIGNOFF notify from server. Added also new function
3337 silc_client_replace_from_channels to replace old ID entry with
3338 new ID entry on all channels. Used when received NICK_CHANGE
3341 * Fixed ID Cache list handling in silc_idlist_get_client in
3342 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3343 to get (or query) client by ID.
3345 * Updated TODO list.
3347 * Added connection authentication status message defined by the
3348 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3349 support for these into the code in client and server side.
3351 * Added generic function silc_client_send_command to send any command
3352 with variable argument list. Application should use this function
3353 to send commands if the command functions provided by the library
3354 does not suite for the application's user interface needs.
3356 * Added new `failure' client operation. Application is notified about
3357 received failure packet if client is executing a protocol. In this
3358 case the protocol's execution has failed.
3360 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3361 is required by the protocol.
3363 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3364 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3367 * Added status flag to SilcSKE object to indicate realtime status
3368 of the SKE protocol.
3370 * Application receives now exactly same command reply arguments as
3371 the library receives from server. However, if ID is received the
3372 corresponding ID entry is returned to the application (eg. Client
3373 ID is mapped to correct SilcClientEntry entry and that is returned).
3374 Changed command_reply client operation due to this change.
3376 * Changed all ID's in commands and in command replys as ID Payloads.
3377 Change affected both client and server side codes.
3379 All ID's sent in SILC network (with execption of ID's in SILC
3380 Packet header) are sent in ID Payload to support variable length
3383 * Server now notifies nick changes and notifies all clients on
3384 the channels about the new nickname (about the new Client ID,
3387 * Implemented CMODE command to change channel modes. Supports all
3388 channel modes defined by the protocol specs except ban and invite
3389 lists. (Also, private channel key mode is supported but support for
3390 setting private channel key in client is missing, thus, this mode
3391 has no effect on client side (except that server requires that the
3392 client uses private channel key and normal channel traffic does not
3395 Also, invite mode works per se, but INVITE command does not work
3396 yet correctly, so you can set channel as invite only channel but
3397 inviting clients to the channel does not work (it is yet to be
3398 thought what's the best way to do it).
3400 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3401 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3402 Implemented CUMODE command to change user's mode on the channel.
3403 Supports all modes defined by the protocol specs.
3405 * Added NAMES command reply to return users modes on the channel.
3407 * Removed unnecessary and slow ciphers from lib/silccrypt.
3409 * Set SO_KEEPALIVE option to connection sockets by default.
3411 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3413 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3414 redefined the Notify Payload into protocol specs.
3416 * Added silc_id_payload_parse_id to get ID directly from raw
3419 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3422 accept searching by Client ID as well.
3424 * Added support for LEAVE and SIGNOFF notify types in client library.
3426 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3427 to parse ID Payload from raw data.
3429 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Added flags parameter into silc_ske_assemble_security_properties
3432 function in lib/silcske/silcske.[ch].
3434 * Changed notify client operation to fit better for notify messages
3435 sent by server. The notify payload received from server is now
3436 passed to the application (after parsing it to SilcNotifyPayload).
3437 It is application's responsibility to retrieve the arguments
3438 from the payload and show the message the way it wants. The message
3439 sent by server is implementation specific.
3441 * Changed public keys to comply with the protocol specification.
3442 Old public keys are not supported anymore and are not compatible.
3444 * Removed nickname from Channel Payload as the latest draft removed
3445 it. The client must resolve the nickname from the NAMES command
3446 reply received when it joined the channel.
3448 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3450 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Fixed some errors in protocol specification drafts.
3454 * Created lib/silccore/silcnotify.c to implement Notify Payload
3455 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3456 generic payloads described by protocol specifications. The file
3457 includes implementations for ID Payload and Argument Payload.
3459 * Changed Command Payload implementation to use the new Argument
3460 Payload. Changed command_xxxx_payload to command_payload_xxxx
3461 to comply with SILC coding conventions.
3463 * Added suppport for Argument Payload handling in Notify Payload
3464 implementation as protocol requires it. Added the new support
3465 into server and client lib as well.
3467 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3469 * Added support for multiple nicknames on same channel. [n] is
3470 added locally to the nickname if there are more than one same
3471 nicknames on the channel.
3473 * Server now sends all nicknames that matched WHOIS request.
3474 Client also shows the list received from server.
3476 * Added TOPIC command to client side. User can now set and show
3477 current topic on channel.
3479 * Added MOTD command to client and server. Also, server sends the
3480 motd when client connects to the server.
3482 * Changed version strings to comply ISO 8601.
3484 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Fixed protocol error handling in client library. It should now
3487 cope even if the SKE fails for some reason.
3489 * Made new protocol specification drafts for submitting to IETF.
3491 * Implemented TOPIC command to server in silcd/command.c.
3493 * Added two new notify types into lib/silccore/silcnotify.h:
3494 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3495 notify nickname change and topic setting/change on a channel.
3497 * API change of command_reply operation in client library. The
3498 application gets now the status type received from server as well.
3500 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3504 * Cras fixed and optimized the packet handling even further and
3505 it should work now. Minor change to the prototype of function
3506 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3508 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Added new function into lib/silcutil/silcschedule.[ch]:
3511 silc_schedule_with_fd to select() a specified fd. The function
3512 returns after timeout expires or data arrives or goes. The
3513 function is used by packet routines to wait that all data is
3514 received from network.
3516 * Fixed data reading from network in lib/silccore/silcpacket.c.
3517 The code now assures that all data is read from the fd and then
3518 continues packet processing. This was a bug fix since the code
3519 used to drop some data in some circumstances.
3521 * Added new function into lib/silcclient/client.[ch]:
3522 silc_client_start_key_exchange to start key exchange after
3523 connection has been established to server. The code internally
3524 now uses this funtion but its main purpose was to provide it
3525 for applications that perform their own connecting. After
3526 application has created a connection it merely calls this
3527 function to start the key exchange between client and server.
3528 The library takes care of everything else after that.
3530 Updated also lib/silcclient/README to explain the usage of
3533 * Do not send to application information that connection has
3534 been established. Application gets notified it by connect
3537 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3539 * Applied cras's patch to add silc_schedule_one function. The
3540 function runs scheduler once and returns.
3542 * Fixed the scheduler after cras messed it up. The timeout
3543 handling works now as it's supposed to work.
3545 * Added into lib/silccore/ silcnotify.h to include notify
3546 message types support. Changed silc_server_send_notify*
3547 functions, in server.[ch], to support those new notify types.
3548 Added the support for the notify types into client library,
3549 as well. Added new notify client operation into ops.h in
3552 * Changed silc_server_packet_send_to_channel to send normal
3553 packets instead of just channel message packets. The function
3554 is now used to send the notify packets to channels. It is not
3555 used to send channel message packets anymore, as server never
3558 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3559 va_arg()s as it seems to require it nowadays. I guess, if SILC
3560 is compiled with older va_arg() the new code should work anyway.
3562 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Splitted core library. Core library (lib/silccore) includes
3565 now only SILC protocol specific core (and common) components.
3566 Created new utility library (lib/silcutil) that includes more
3567 generic purpose stuff. The stuff for util library was taken
3568 from the old core library. This was minor and easy split.
3570 * Created SILC Client Library (lib/silcclient) that includes
3571 implementation of the SILC client without user interface. This
3572 was major move from silc/ directory. The code has been changed
3573 so that it is transparent towards the user interface. The
3574 silc/ directory includes now the same user interface as before
3575 and it uses the new client library. Read lib/silcclient/README.
3576 Basicly, the client library performs everything else related
3577 to SILC except user interface handling. Also, configuration
3578 files are considered to be part of user interface and library
3579 does not handle them.
3581 This change also changed a lot of structures, function naming etc.
3582 Most important change was that SilcClientWindow object was
3583 renamed to SilcClientConnection in the client library. Created
3584 also new file lib/silcclient/ops.h. Also added new files
3585 silc/local_command.[ch] and silc/client_ops.[ch].
3587 All these changes were made to make it easier for user interface
3588 designers to create what ever user interface for the SILC client
3591 It is also expected that the server will be moved to lib
3592 directory as well and SILC Server Library will be created;
3593 sometimes in the future.
3595 * Removed Local commands from lib/silccore/silccommand.h as
3596 they are application specific and new client library does not
3597 handle any of those anymore.
3599 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3600 old client implementation in silc/.
3602 * Added support for callback functions in SILC_LOG_* macros.
3603 Application can now set its own callbacks that will be called
3604 instead of using the default functions that will always print
3605 the debug messages to stderr (or stdout). Also, debugging can
3606 now be disabled by setting silc_debug to FALSE and re-enabled by
3607 setting it to TRUE. Note, that logging will still work even
3608 if debugging is disabled.
3610 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3611 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3612 silc_log_reset_debug_callbacks.
3614 * To enable debugging in silc client one must give now -d
3615 option on command line.
3617 * Changed silc_schedule_init to automatically allocate task queues
3618 if they are not allocated before calling it.
3620 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Added GMP 3.1 into math library.
3624 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3626 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3627 a channel in SILC network. The packet is used by servers and
3628 routers to notify other routers that user has left a channel.
3629 This little feature was missing until now. Added the feature
3630 to protocol specification as well.
3632 Added functions: silc_server_send_remove_channel_user and
3633 silc_server_remove_channel_user into server.[ch].
3635 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3636 lib/silccore/silcpacket.h. However, they are not implemented
3639 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * Fixed joining to a channel and sending channel messages
3642 between server and router. The channel message sending should
3643 now work inside a cell.
3645 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Fixed the private message sending between server and router.
3648 The private message sending should now work inside a cell.
3650 * Added silc_server_replace_id into server.[ch] to replace
3651 existing ID in the SILC network.
3653 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3654 and silc_idlist_replace_server_id into idlist.[ch] in server.
3656 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Fixed the server to server connections. Server can again now
3659 connect to router. Router to router connections probably does
3662 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Added dynamic protocol registering support. Now protocols can
3665 registered and unregistered on the fly. Patch by cras.
3667 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3669 * Added lib/contrib directory to hold routines that some platforms
3670 don't have but are needed by SILC.
3672 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3673 into lin/contrib to provide getopt() and getopt_long() for
3674 those who don't have it.
3676 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Added AWAY command to client. When away message is set and
3679 client receives a private message packet the client automatically
3680 replies to the sender with the away message.
3682 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3683 bug seemed to be the cause of recent problems when compiling
3686 * Added version detection support to SKE protocol specification
3687 and added the new changes to the SKE implementation as well.
3688 There were other minor changes in the SKE protocol as well.
3690 Many changes in lib/silcske/silcske.[ch] and in
3691 lib/silcske/payload.[ch].
3693 * Added ^U functionality, clear input line. Patch from cras.
3695 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Mainly small bugfixes on core library. Fixed some debugging
3698 logging and buffer overflow in silclog.c.
3700 * Updated config.sub and config.guess on the distribution tree.
3702 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3704 * Added command lagging support in server. Client may execute
3705 commands now only once in two seconds.
3707 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * Optimized packet reception. MAC computation and checking is now
3710 also more optimized. A lot previously duplicated code is now
3711 used as generic by both client and server.
3713 * Fixed key pair generation in clientutil.c
3715 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * Added into lib/silccore/silcbufutil.[ch] new function;
3718 silc_buffer_realloc.
3720 * Moved generic packet sending/encryption functions to
3721 lib/silccore/silcpacket.[ch] from client and server. Some
3722 rewriting of the functions.
3724 * Moved all generic packet reception/decryption functions to
3725 lib/silccore/silcpacket.[ch] from client and server. The
3726 packet processing is now much cleaner in both client and server.
3727 These were major changes in both client and server.
3729 * Created many common functions in server to do packet sending.
3730 Previously code were duplicated a lot, this has been removed
3733 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3735 * Rewrote major parts of the ID cache system. Don't know
3736 whether it is better now or not but at least the API is more
3739 * Major rewrite on ID cache stuff on client because of the ID
3740 cache API changes. Added idlist.c to client.
3742 * Also major rewrite on ID cache stuff on server as well.
3743 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3744 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3745 in hand, instead they are all put into the ID cache system now.
3746 All server_idlist_* routines uses ID cache now instead of
3747 traversing its own lists (those lists does not exist anymore).
3748 SilcIDList though still exists. Also, SilcXXXEntry's are
3751 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Finally made the SKE implementation compliant to the protocol
3754 specification. All mp integers are now binary encoded as
3755 opposed being HEX encoded.
3757 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3760 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3761 functions: silc_[encode/decode]_pem. Also added function
3762 silc_encode_pem_file to PEM encode with newlines ('\n') for
3765 * SILC public keys are now encoded either PEM or binary. Same
3766 option is for private keys as well. By default private keys
3767 are binary encoded and public keys PEM encoded. Silly HEX
3768 encoding were removed.
3770 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3771 function to create fingerprints.
3773 * Fixed a bug in SHA1; does not change the original data anymore.
3775 * Partly implemented INFO command on client and server side.
3776 Fixed CLEAR command. Changes to SERVER command; show current
3777 server(s) when giving command without arguments. Added
3778 VERSION command to client.
3780 * Added check to server that unregistered connections cannot
3781 execute commands (unless it is specificly allowed).
3783 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Fixed screen refresh.
3787 * Fixed channel joining bug from client. On some circumstances
3788 client tried to join to a channel it had already joined.
3790 * Added public key verification process into client's protocol.c.
3791 The client now verifies the public key from user and saves
3792 it into ~./silc/serverkeys/ directory.
3794 Added into: clientutil.[ch]: silc_client_verify_server_key.
3796 * Changed SKE protocol's silc_ske_initiator_finish function
3797 to accept callback function that verifies the received public
3798 key. Removed old silc_ske_verify_public_key function.
3800 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3802 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3803 silc_pkcs_private_key[_data]_set.
3805 * Made the password and public authentication more cleaner in
3806 server's protocol.c.
3808 * Removed historic and obsolete protocol `channel_auth' from
3809 both client and server.
3811 * Removed wrong way of sending command status messages from
3812 server to client in server's command.c. The old way violated
3813 protocol specification.
3815 Changes to silccore/silccommand.[ch]: removed
3816 silc_command_encode_status_payload -> not needed anymore,
3817 changed silc_command_encode_payload_va to accept extra
3818 argument on variable argument list. The argument type must
3819 now be provided to the function. Also, added new function:
3820 silc_command_encode_reply_payload_va which is same as
3821 normal command_encode_payload_va except command status type
3822 is provided as extra argument.
3824 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Added ~./silc directory handling. The directory includes the
3827 public and private keys for the client.
3829 Added silc_client_check_silc_dir, silc_client_create_identifier
3830 and silc_client_load_keys.
3832 * Implemented SILC protocol compliant public key. Added public
3833 and private key saving to and loading from files.
3835 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3836 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3837 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3838 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3839 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3841 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3842 silc_pkcs_load_[public/private]_key.
3844 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * Added silc_server_get_route (route.[ch]) to get connection
3847 data for the fastest route for given ID.
3849 * Implemented INVITE command on client and server. The command
3850 were re-defined in the SILC Protocol Specification and the
3851 implementation now complies with the specification.
3853 * Implemented PING command on client and server.
3855 * Implemented NAMES command on client and server. The server side
3856 supports currently only normal server not router server yet.
3857 Some changes to NAMES definition in SILC protocol specification.
3859 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Implemented LEAVE command on client and server.
3863 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
