3 * Added checking to the server code not to start the server if
4 ciphers and stuff are not configured properly. Affected files
5 silcd/serverconfig.[h] and silcd/server.c.
7 * Changed the layout of the header files of the public interfaces
8 in the SILC libraries. The new layout supports ROBODoc
9 documentation tool (and some others) so that it is easy to create
10 a library reference manual. All the other headers and source
11 code must still follow the CodingStyle document. Also source
12 code must not include these ROBODoc stuffs, only the headers.
13 Furthermore, all public interface headers must now be named
14 by using `silc' prefix, example: silcapi.h, silccipher.h.
15 Some files were renamed due to this. All the other headers
16 must not be used as public interfaces. I will update the
17 CodingStyle document later. Changed following headers, so far:
19 lib/silcclient/silcapi.h
20 lib/silccore/silcauth.h
21 lib/silccore/silcprivate.h
22 lib/silccrypt/silcdh.h
24 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
28 * Removed silc_client_packet_send_flush from the client library
29 as it is not needed. Affected file lib/silcclient/client.[ch].
31 * Added printing of message of unresolved authentication method
32 to the Irssi SILC client. Added it to the module formats.
33 Removed the same message from the client library.
35 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
37 * Added new distribution feature, DISTLABEL. Every distribution
38 can define own preprocessor label that can be used in the
39 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
40 file distributions, acconfig.h.pre and prepare.
42 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
44 * Added Makefile.defines_int to include the actual definitions
45 for Makefile.defines.in. Tested the new distribution system,
46 created distributions and tested installation.
48 * Added AWAY message printing to the Irssi SILC client. Added
49 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
51 * Added SCONNECT command to call the SILC's CONNECT command.
52 Cannot use CONNECT directly since Irssi uses that internally.
53 Affected file irssi/src/silc/core/silc-servers.c.
55 Added ACTION local command. It is same as ME command but takes
56 the channel as mandatory argument.
58 Rewrote some of the Irssi's help files to suite for SILC
61 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
63 * Added Makefile.defines[.in] that should for now on be included
64 in all Makefile.am file in the source tree. That file includes
65 all common compilation definitions for SILC source tree.
67 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
69 * Minor changes to the ./prepare script to change the package
70 name according the distribution name to the configure.in.
72 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
74 * Created new distribution system. Added file `distributions'
75 that defines all the distributions that can be created out of
76 the SILC source tree. The ./prepare script now reads that
77 file to determine how to prepare the distributions. The
78 first argument to the ./prepare is the name of the distribution
79 and second is the version of the distribution. If given
80 without arguments it creates the default (toolkit) distribution
81 with the default version (defined in ./prepare).
83 All Makefile.am files that are subject to the distributions
84 are now named as Makefile.am.pre. These are ./Makefile.am
85 and lib/Makefile.am. Others may be changed later.
87 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
89 * Added invite list, ban list, some key management and connection
90 error message printing to module formats in the Irssi SILC client.
92 * Added new silc_client_set_away_message to set the away message
93 that is back to the person who sent private message. The
94 affected file lib/silcclient/silcapi.h and the
95 lib/silcclient/client_prvmsg.c.
97 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
99 * Fixed the private message sending in the Irssi SILC client,
100 added local command KEY to the Irssi SILC client.
102 Added key management and key agreement message formats to the
103 irssi/src/fe-common/silc/module-formats.[ch].
105 Added USERS (alias WHO) printing, server/router operator
106 indication and LIST command printing to the module formats.
108 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
110 * Fixed channel joining notify handling, cumode notify handling
111 from Irssi SILC client.
113 * Added SILC specific module-formats to the Irssi SILC client so
114 that SILC specific message hilighting, colors etc is possible.
115 Affected file irssi/src/fe-common/silc/module-formats.[ch].
117 Added channel mode, channel user mode, actions, notices,
118 whois and whowas printing to the the module-formats.c.
120 * Fixed a bug in channel deletion in the server. The channel
121 is not left to the cache even if the channel founder auth mode
122 is set when there are no users anymore on the channel. Affected
125 * The silc_net_localhost now resolves the entire hostname including
126 the domain name. Affected file lib/silcutil/silcnet.c.
128 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
130 * Changed the ask_passphrase client operation to be ascynchronous.
131 It has now a completion callback and a context that the
132 application must call after it has got the passphrase from
133 the user. Affected files lib/silcclient/silcapi.h,
134 lib/silcclient/protocol.c, lib/silcclient/command.c and
137 Added SilcAskPassphrase callback that the application calls
138 to deliver the passphrase to the library.
140 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
141 The public key verification and especially a certificate
142 verification is asynchronous procedure.
144 Added new SILC_SKE_STATUS_PENDING status to indicate the
145 request is pending and a callback will be called to finalize
148 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
149 indicate that remote end did not send its public key (or
150 certificate), even though we require it. Added check for this
151 condition in the SKE. This was a security bug, now fixed.
153 Defined new SilcSKEVerifyCbCompletion callback that is called
154 when the verification process is completed.
156 The affected files lib/silcske/silcske_status.h and
157 lib/silcske/silcske.[ch].
159 * Changed the verify_public_key client operation to be async
160 as well. Defined SilcVerifyPublicKey callback that is used to
161 indicate the success of the public key verification process.
163 Changed the server and client to use the new async client
166 * Changed the Irssi SILC client's internal scheduler to be called
167 twice as many times as it used to be. As a result the client
168 should be a bit faster now. Affected file is
169 irssi/src/silc/core/silc-core.c.
171 * Added support to Irssi SILC client of asynchronous public key
172 verification and passphrase inquiry. Affected file is
173 irssi/src/silc/core/silc-core.c.
175 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
177 * Do not say "You have left channel %s" in client library.
178 Moved it to the application. Affected files are
179 lib/silcclient/command.c and silc/client_ops.c.
181 * Fixed silc_client_get_clients. Command context was not
182 duplicated and was freed memory in the callback. Affected
183 file lib/silcclient/idlist.c.
185 * Do not say "you are now talking..." on JOIN command in the
186 client library. The appliation must handle it.
188 * Do not say ".. changed topic to" in command reply in the
189 client libary. The application must handle it.
191 * Fixed TOPIC command sending in the client library.
193 * Fixed a memory leak in silc_client_command_free in the file
194 lib/silcclient/command.c.
196 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
198 * Imported a modified version of Irssi client to the source tree.
199 The Irssi will be used to create a new client called
200 Irssi SILC. Imported to irssi/.
202 Added silc_core_init_finish function to the Irssi. Affected
203 file irssi/configure.in.
205 A lot changes in the Makefile.ams around the irssi tree.
207 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
209 * Do not rehash if the new size is same as the old size of the
210 hash table, in the silc_hash_table_rehash*. The affected file
211 lib/silcutil/silchashtable.c.
213 * Replaced hash_table_del_by_context calls from the server
214 (when channel->user_list and client->channels) to the
215 hash_table_del as it is sufficient and faster.
217 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
219 * Added silc_hash_table_list, silc_hash_table_get and the
220 SilcHashTableList structure to provide an alternative way to
221 traverse the hash table. The affected files are
222 lib/silcutil/silchashtable.[ch].
224 * Changed the server's idlist routines to use the hash table
225 routines to optimize the code.
227 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
229 * Replaced the client entry's `channel' list and channel entry's
230 `user_list' list to hash tables for optimized lookup. Changed
231 the code to use the hash table interface around the code.
232 Affected file lib/silcd/idlist.[ch].
234 * Added `auto_rehash' boolean argument to the function
235 silc_hash_table_alloc to indicate whether the hash table should
236 auto-rehash when it thinks is appropriate time. It will
237 increase the hash table size if the there is twice as much
238 entries in the table than the size of the table, and will
239 decrease the size if there are twice as less entries than
240 the size of the table.
242 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
244 * Fixed silc_xxx_get_supported to not crash at some circumstances.
246 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
248 * silc_idcache_purge_by_context deletes the entry now by context
249 as it is supposed to do. Affected file lib/silccore/idcache.c.
251 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
252 client is not anymore valid (WHOWAS givens the info) and not
253 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
255 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
257 * Removed the `data' and `data_len' arguments from the ID Cache
258 interfaces and added `name' argument. ID Cache does not handle
259 anymore the binary data only a names associated with given ID.
261 * When hashing a Client ID with silc_hash_id the entire ID is
262 not hashed anymore, instead only the hash of the Client ID is
263 hashed. This way we can access the Client ID from the cache
264 with Client ID but with the hash of the ID (which is a hash of
265 the nickname) as well without any difference in performance.
267 Added also silc_idcache_find_by_id_one_ext to do one on one
268 searching when we have the actual ID. Added also function
269 silc_hash_client_id_compare. The affected files are
270 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
272 * When hashing the name associated with a ID it is always done
273 in lowercase. This way we can access the cache without worrying
274 about case-sensitivity, even though, for example nicknames are
277 * Fixed a bug in server with channel message sending. It put
278 wrong ID type as destination ID. The affected file
281 * silc_idcache_del_by_context now deletes from all hash tables
282 by context. Affected file lib/silccore/idcache.c.
284 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
286 * Changed the client library to use the new ID Cache interface.
287 Changes around the source tree.
289 * Added silc_hash_table_rehash_ext to rehash with specific
290 hash function. Affected file lib/silcutil/silchashtable.[ch].
292 * Added silc_hash_string_compare to compare two strings in the
293 hash table. Affected file lib/silcutil/silcutil.[ch].
295 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
297 * Added new function silc_idcache_del_by_context into the
298 lib/silccore/idcache.[ch].
300 * Changed the server's ID list routines to use the new ID Cache
301 interface. Changes around the source tree.
303 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
305 * Added silc_hash_table_del[_by_context]_ext functions in to the
306 lib/silcutil/silchashtable.[ch].
308 Removed silc_hash_table_find_all* routines and added new
309 silc_hash_table_find_foreach to replace them.
311 Added silc_hash_table_replace_ext function as extended
312 replacing function. Separated the simple hash table interface
313 from the extended hash table interface in the file
314 lib/silcutil/silchashtable.h.
316 * Fixed minor bugs and changed it to use some of the new
317 hash table functions in lib/silccore/idcache.c
319 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
321 * Added new function silc_hash_table_find_all to return all keys
322 in the hash table by the specified key. As the hash table is
323 collision resistant it also makes it possible to have several
324 duplicate keys in the hash table. This function may be used to
325 find all of the keys from the hash.
327 Added user_context arguments to the SilcHashFunction,
328 SilcHashCompare and SilcHashDestructor to deliver user specified
331 Added new fuctions silc_hash_table_find[_all]_ext to do
332 extended lookup with specified hash and compare functions and
333 specified user contexts.
335 Added new function silc_hash_table_add_ext to add the key
336 with specified hash function and user context.
338 Added new function silc_hash_table_foreach to traverse all
339 entrys in the hash table. Added SilcHashForeach callback
342 Added new function silc_hash_table_del_by_context to delete
343 the entry only if the context associated with the key matches.
345 Affected files are lib/silcutil/silchashtable.[ch].
347 * Removed silc_hash_[server/client/channel]_id and added just
348 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
349 silc_hash_id_compare to compare two ID's using as the hash table
350 comparison function. Added also silc_hash_data to hash
351 binary data and silc_hash_data_compare to compare it.
353 * Removed silc_idlist_find_client_by_hash as it is not needed
354 anymore. Affected file silcd/idlist.[ch].
356 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
357 to use internally the SilcHashTable. The new ID Cache is a lot
358 faster than the old one. Some of the ID Cache interface was also
359 rewritten and obsolete and stupid functions were removed.
361 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
363 * Added entry_count field to the SilcHashTable to keep the number
364 of the entries in the table. Implemented the function
365 silc_hash_table_rehash. Added new function
366 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
368 Fixed a minor bug in silc_hash_table_free.
370 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
371 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
372 into the lib/silcutil/silcutil.[ch].
374 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
376 * Implemented a collision resistant hash table into the
377 lib/silcutil/silchashtable[ch]. See the header and the source
378 for the SilcHashTable API.
380 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
382 * Merged dotconf version 1.0.2 into lib/dotconf.
384 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
386 * Do not compile anything in lib/silcsim/* if the SIM support
387 is not enabled. The tree should now compile without problems
390 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
392 * Compiled the SILC under cygwin. Compiled and tested briefly
393 without problems. More tests needed. The SIMs didn't compile
396 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
398 * Fixed possible crash in silc_get_username in the
399 lib/silcutil/silcutil.c.
401 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
403 * Fixed a va_arg in silc/client_ops.c.
405 * Oops, RC5 routines were named AES and caused some problems
406 when not using SIM's. Affected file lib/silccrypt/rc5.c.
408 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
410 * Added new SilcIDIP structure into the lib/silccore/id.h and
411 replaced the old `ip' fields from all SILC ID's to that type.
412 This is a step towards IPv6 support.
414 The silc_id_get_len takes now the ID as an extra argument.
415 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
416 both IPv4 and IPv6 based ID's.
418 The affected files are lib/silccore/id.[ch] and other files
419 around the tree using these routines.
421 * Removed the ID length arguments in server from various
422 silc_server_send_notify_* routines -> they are not needed
425 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
427 * Fixed memory leak in silc_encode_pem_file in the file
428 lib/silcutil/silcutil.c.
430 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
432 * Check minor version as well in the SKE. Affected files are
433 silcd/protocol.c and lib/silcclient/protocol.c.
435 * Added --identifier option to the server so that an identifier
436 can be when creating the public key for the server. Affected
437 file is silcd/silcd.c.
439 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
440 lib/silccrypt/silcpkcs.c.
442 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
444 * Register default ciphers and stuff when using -C option with
445 the server. Affected file sildc/silcd.c.
447 * Put back the servers public key filename format, it is better
448 than the new one. For now, the client keys are saved with the
449 new filename format. The affected file silc/client_ops.c.
451 * Implemented the Cipher API for the rest of the ciphers that
452 did not implement it or implemented it the wrong way.
454 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * Register default ciphers and stuff when using the -S option
457 in the client. Affected file silc/silc.c. Same also when
458 creating new key pair with -C option.
460 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
462 * Fixed the silc_verify_public_key client operation function to
463 save the public keys differently. The fingerprint is now
464 used as filename and not the hostname. This way also the
465 client keys are saved uniquely and not with hostnames. The
466 affected file is silc/client_ops.c.
468 * Trimmed the silc_hash_fingerprint function to remove extra
469 whitespaces from the end of the fingerprint. The affected
470 file is lib/silccrypt/silchash.c.
474 * Added silc_cipher_register_default function to register all
475 default ciphers. It can be used when configuration files
476 does not exist and the application does not want any specific
477 ciphers in any specific order.
479 The SilcDList is now used as silc_cipher_list dynamically
480 allocated cipher list. Removed the static list all together
481 and now all ciphers must be allocated to the dynamic list.
482 The silc_cipher_alloc routine was changed to check only the
485 All silc_cipher_* routines that used to return int returns
488 The affected files lib/silccrypt/silccrypt.[ch].
490 * The same thing was done to silc_hash_* as for silc_cipher_*
491 routines. Affected files lib/silccrypt/silchash.[ch].
493 * The same thing was done to silc_pkcs_* as for silc_cipher_*
494 routines. Affected files lib/silccrypt/silcpkcs.[ch].
495 Added also silc_pkcs_[un]register[_default] functions.
496 Removed the data_context from the PKCS API.
498 * Added silc_hmac_register_default function to register default
499 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
500 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
501 to unregister all hmacs at once.
503 * Register the default ciphers, hash functions, PKCSs and HMACs
504 if client's configuration file does not exist. The affected
507 * The client did not load the hash functions from the SIM
508 modules at all. Added support for this. Affected file is
511 * When decoding public key with silc_pkcs_public_key_decode, check
512 the supported algorithm only if PKCS are registered. Affected
513 file lib/silccrypt/silcpkcs.c. The same was done with the
514 silc_pkcs_private_key_decode.
516 * Fixed the SILC List routines to keep the list always in order.
517 It used to change the list's order when traversing the list but
518 not it preserves the order. Affected file lib/trq/silclist.h.
520 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
522 * Added the client library to use the SilcSocketConnection's
523 reference counter (by silc_socket_dup) to prevent the bug that
524 the socket object may be freed underneath async operation.
526 * The name resolv library checking fixes in the configure.in.pre.
529 * Created new version of the protocol drafts for future
530 development. The -03 drafts are the ones that will be changed
531 in the trunk now and the -02 will remain as they are.
533 * Send list of CUMODE notifys to the router when announcing
534 the channel users to the router. Affected file silcd/server.c.
535 If the router receiving channel founder CUMODE for a channel
536 that already has channel founder it will send CUMODE notify
537 to the sender to remove the channel founder rights from the
538 announced client. Affected file silcd/packet_receive.c.
540 * The CUMODE notify may now use Server ID as well as the entity
541 who changes the mode. Updated protocool specs.
543 * Updated INSTALL and README files.
545 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
547 * New web pages in the http://silc.pspt.fi. The pages was
552 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
554 * Implemented the [DenyConnectin] config section in the server.
555 Added silc_server_config_denied_conn to check whether incoming
556 connection is denied. Affected file silcd/serverconfig.[ch].
558 * Do not check the ports when checking the incoming configuration
559 data if the port is 0, meaning any. Affected file is
560 silcd/serverconfig.c.
562 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
564 * Fixed buffer overflow in silc_string_compare in the file
565 lib/silcutil/silcutil.c.
567 * Fixed double free in silc_server_command_leave in the file
570 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
572 * Fixed the version checking in the server. Affected file is
575 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
577 * Fixed the configuration data fetching when accepting new
578 connections in the server. Affected file silcd/server.c.
580 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
582 * Added `sender_entry' argument to the function
583 silc_server_packet_relay_to_channel so that we can check
584 whether some destination actually belongs to the same route
585 the sender belongs (ie, we must not resend the packet to the
586 sender). Affected file silcd/packet_send.[ch].
588 * Added `servername' field to the SilcClientEntry in the server
589 to hold the name of the server where client is from. Affected
590 file is silcd/idlist.h.
592 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
594 * Moved the channel message encrypting in the router betwen
595 router connections from silc_server_channel_message to the
596 silc_server_packet_relay_to_channel since we want to check
597 whether we have anybody channel before encrypting anything.
598 Affected files silcd/packet_[receive/send].c.
600 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
602 * Fixed the [AdminConnection] server config section to support
603 multiple entries. Affected file silcd/serverconfig.c.
605 * Added support into the server to check the validity of the
606 incoming connection before executing any KE or authentication
609 * The connection configuration is now saved to the KE and
610 connection auth protocol contexts and not fetched anymore in
611 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
613 * The local hosts listenning address and port is also resolved
614 now when starting the server. We want to have the socket object
615 to include the real address and port for the listener. Added
616 new function silc_net_check_local_by_sock into the files
617 lib/silcutil/silcnet.[ch].
619 * Fixed a broadcast bug in server -> do not broadcast if we
622 * Fixed a routing bug. Do not route broadcast packets ever.
623 Broadcast packets must be processed always and not routed since
624 they may be destined to some other host than yourself and thus
625 would get routed without no good reason. Affected file is
628 * Added function silc_server_config_is_primary_route to check
629 whether primary router connection has been configured (a router
630 configuration that we are initiating). If there is not, we
631 will assume that there is only two routers in the SILC network
632 and we will use the incoming router connection as our primary
633 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
635 * Changed the order of the broadcasting. Broadcast _after_ the
636 packet has been processed not before. Affected file is
639 * Fixed a [ClientConnection] parsing bug. The port was never
640 parsed correctly thus resulting to port 0. Affected file
641 silcd/serverconfig.c.
643 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
644 argument and did not set the broadcast packet flag. Affected
645 file silcd/packet_send.c. Fixed same bug in the function
646 silc_server_send_notify as well.
648 * If we receive NEW_ID packet for our own ID in the server, ignore
651 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
655 * Removed the nickname from the Private Message Payload.
656 Updated the code and the protocol specs.
658 * Updated protocol specs for submitting to the IETF.
660 * Tweaked the Random Number Generator a bit. Affected file
661 lib/silccrypt/silcrng.c. Exported a new function
662 silc_rng_[global]_add_noise which can be used to add more
665 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
667 * Do not parse packets with different timeout when protocol
668 is active -> may cause problem with rekey. Affected file
671 * When server receives signoff notify it must not create
672 new channel key if the client is on any channels since the
673 sender of the signoff notify will create it.
675 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
677 * Added printing of error messages during SKE protocol from the
678 failure packet sent by server during SKE. Affected file
681 * Removed the client's failure_callback handling with timeout
682 and handle it immediately when received.
684 * The SKE library returned wrong type in SUCCESS and FAILURE
685 packets. They must be 32 bit MSB not 16 bit MSB.
687 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
689 * Ok, rewrote the logic of the re-key and now it seems to work.
690 I tested it on high traffic with frequent re-keys without
691 problems. Added hmac_receive (and renamed hmac to hmac_send)
692 in SilcClientConnection in lib/silcclient/client.h and
693 in SilcIDListData in silcd/idlist.h. Also, removed the
694 SilcPacketParserContext's cipher and hmac fields as they are
695 not needed anymore and actually caused some problems when
696 the ciphers and hmac's changed underneath the packet parser.
698 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
700 * If re-key protocol is active then process the incoming packets
701 synchronously since we must assure that icoming packets encrypted
702 with the old key is processed before the new keys is set to
703 use. This is true other packets than for REKEY packets.
704 Affected file silcd/server.c. The same was done to client library
705 as well, affected file lib/silcclient/client.c.
707 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Fixed bug in client and server to accept the force send if
710 the packet is send from silc_[server/client]_packet_process
711 function. Otherwise the packets are never delivered, oops.
713 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
715 * Disable force sending of packets when REKEY protocol is active.
716 We must assure that no packet is sent directly when rekey is
717 performed. All packets must be sent through packet queue.
718 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
719 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
720 function is silc_[server/client]_packet_send_real to check
723 * Replaced the SIM paths from example config files to
724 /usr/local/modules. Also, make install creates now
725 /usr/local/silc/logs directory to hold all the SILC server
728 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Made the configure.in.pre work on Solaris. Patch by salo.
732 * Made all ciphers compatible with non-x86 machines. Defined
733 CBC mode macros into lib/silccrypt/ciphers_def.h.
735 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
737 * Fixed the make install.
739 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * When MAC computation fails the silc_packet_decrypt returned 0
742 even though it was supposed to return -1. Fixed this. The
743 affected file is lib/silccore/silcpacket.c.
745 * Do not replace the config files in /etc/silc (in make install)
746 if they already exist. Affected file ./Makefile.am.
748 * Do not send re-key packets immediately but through packet queue.
749 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
751 * Changed silc_net_check_host_by_sock to return FALSE if the
752 IP/DNS could not be resolved. Though, it returns the IP address
753 now even if it could not resolve it (but returns also FALSE).
754 Affected file lib/silcutil/silcnet.[ch].
756 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
758 * Added silc_pkcs_decode_identifier to decode the public key's
759 identifier. Affected file lib/silccrypt/silpkcs.[ch].
760 Added also silc_pkcs_free_identifier. Added also new context
761 SilcPublicKeyIdentifier.
763 * Added -S option to the silc client. It is used to dump the
764 contents of the specified public key file.
766 * Changed the PKCS api to return the public key length when
767 setting the public key.
769 * Fixed a fatal bug in the public and private key file loading.
770 Affected file lib/silccrypt/silcpkcs.c.
772 * Execute the packet parsing for client with zero (0) timeout
773 if the protocol is active. Affected file silcd/server.c.
775 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
777 * Made the key generation options to the silcd program. Added
778 -C option, equivalent to client's option.
780 * Added new [ServerKeys] config section to the server. It
781 configures the server's public and private key.
783 * Defined generic Public Key Payload into the protocol
784 specification to send specific type of public keys and
787 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
788 public key or certificate.
790 * Implemented the GETKEY command to the server and to the
791 client library and on user interface.
793 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
795 * Made preliminary `make install' work.
797 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
799 * Added SilcServerRekey context into silcd/idlist.h.
801 * Added the PFS support as defined in the specification to the
802 SKE protocol. Affected files lib/silcske/*.c.
804 * Added `ske_group' field to the SilcServerRekey context to hold
805 the number of the SKE group that is used with PFS in re-key.
806 Affected file silcd/idlist.h.
808 * Added PFS re-key support to the server. Affected file is
811 * Added silc_protocol_cancel to cancel execution of the next
812 state of the protocol. Affected file is
813 lib/silccore/silcprotocol.[ch].
815 * Added the re-key support with and without PFS to the client
816 library. Re-key is performed once in an hour, by default.
818 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
819 Added silc_client_rekey_callback and silc_client_rekey_final.
820 Affected files are lib/silcclient/protocol.[ch] and
821 lib/silcclient/client.[ch].
823 * Removed the `hmac_key' and `hmac_key_len' fields from the
824 SilcClientConnection structure; not needed. Affected file is
825 lib/silcclient/client.h.
829 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
831 * Do not ask whether user wants to use the negotiated private key
832 for private messages, just use it. Affected file is
833 silc/local_command.c.
835 * Added `send_enc_key' and `enc_key_len' fields to the
836 SilcIDListData structure since they are needed in the re-key
837 phase. Affected file is silcd/idlist.[ch].
839 * Implemented the simple re-key protocol into the server.
840 Affected files silcd/server.c and silcd/protocol.[ch]. The
841 re-key will be performed once in an hour, by default.
843 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
844 Added silc_server_rekey, silc_server_rekey_callback and
845 silc_server_rekey_final.
847 * Removed Tunneled flag from the protocol. Updated the code
848 and the specifications.
850 * Adde `pfs' field to the SilcIDListData to indicate whether
851 the PFS is to be performed in the re-key. Affected file is
854 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
856 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
857 int64 of at least the xintXX size. If void * is less that 4
858 bytes uint32 * will be used. Defined bool as boolean.
860 * Changed _ALL_ unsigned long and unsigned int to uint32,
861 unsgined short to uint16 in the source tree.
863 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
864 not handle clients that has entry->data.registered == FALSE.
865 They are not in the network anymore. Affected file is
868 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
870 * Implemented the sending of the SERVER_SIGNOFF notify in the
871 server. Affected file is silcd/server.c.
873 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
874 Added also silc_notify_payload_encode_args into the
875 lib/silccore/silcnotify.[ch].
877 * Implemented ther SERVER_SIGNOFF notify handling in the server.
878 Affected file silcd/packet_receive.c.
880 * Implemented the SERVER_SIGNOFF notify handling in the client
881 library. Affected file lib/silcclient/client_notify.c. Also,
882 implemnted the printing of the SERVER_SIGNOFF info to the
883 application. Affected file silc/client_ops.c.
885 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
886 if the deleting was successful. Affected file silcd/idlist.[ch].
888 * Added support for public key authentication in the connection
889 authentication protocol in the client library. Affected file
890 lib/silcclient/protocol.c.
892 * Changed the server's silc_idlist_get_clients_by_* interface
893 to support already allocated array so that new entries may be
894 added to pre-allocated array. Affected file silcd/idlist.[ch].
895 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
898 * All command reply functions in the server now calls the
899 pending command callback even if error occured. This way the
900 error will be delivered to the client as well. Affected files
901 silcd/command.c and silcd/command_reply.c.
903 * Fixed INFO command to return local server's info if no server
904 was provided. Affected file lib/silcclient/command.c.
906 * Removed RESTART command for good. Updated the code and the
909 * Rewrote parts of the task system. It is a bit simpler now.
910 Removed unsued task priorities. The affected files are
911 lib/silcutil/silctask.[ch].
913 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
915 * Moved the USERS printing from the library to the application.
916 Affected files lib/silcclient/command.c and silc/client_ops.c.
918 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Added channel key re-key support. The re-key is perfomed
923 only by the router and is done once in an hour. Added `rekey'
924 field to the SilcChannelEntry in the server. Affected files
925 silcd/server.c and silcd/idlist.h.
927 * Added silc_task_unregister_by_context into the file
928 lib/silcutil/silctask.[ch].
930 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
932 * Added SILC_UMODE_GONE mode to indicate when the client is not
933 present in the SILC network. Added also support to the local
934 command AWAY that will set this mode. Added support of showing
935 "xxx is gone" in WHOIS command. The USERS command shows the
938 * Fixed setting server and router operator privileges in the
939 server's UMODE command. Affected file silcd/command.c.
941 * Merged the SKE KE1 and KE2 payloads into one payload. The
942 new KE payload is equivalent to the old KE2 payload.
944 Cleaned up the SKE Start Payload parsing. It now uses the
945 simple buffer unformatting to do the parsing. A lot faster
948 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
949 to the SKE that is used to indicate whether both of the SKE
950 parties should perform authentication. By default only the
951 responder performs authentication. By setting this flag also
952 the initiator must do authentication. By default it is unset
953 since in normal SKE case, client to server connection, only
954 the responder should do authentication. When doing SKE between
955 two clients both should perform authentication. Updated the
956 code and the protocol specs.
958 * A little fix to IDENTIFY command in the server. Search the
959 client first by hash not nickname. Affected file is
962 * Fixed the silc_client_close_connection to support closing
963 the client to client connections wihtout deleting too much
964 data. Affected file lib/silcclient/client.c.
966 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
967 are received if protocol used to be active but is not anymore
968 the application would crash due to NULL pointer dereference.
969 Affected files silcd/server.c and lib/silcclient/client.c.
971 * Added `hash' field to the SilcClientConnection to include
972 the hash function negotiated in the SKE protocol.
974 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
975 to set the channel founder authentication data. A client can
976 claim the founder rights later by providing the authentication
977 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
978 This way the channel founder can regain the channel founder
979 privileges even it is left the channel. This works only on
980 local server and the client must be connected to the same
981 server to be able to regain the founder rights. Updated the
982 protocol specs accordingly.
984 Added support to the CMODE command in the client to set the
985 founder auth data. Read the README to see how to set it.
987 Added support to the CUMODE command to claim the founder
988 rights. Read the README to see how to do it.
990 Added support for the founder authentication to the Channel
991 Entry in the server. Affected file silcd/idlist.h.
993 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
994 server's CMODE command. Affected file silcd/command.c.
996 * Added the following new functions into lib/silccore/silcauth.[ch]:
997 silc_auth_get_method and silc_auth_get_data.
999 * The server now saves the remote hosts public key to the
1000 SilcIDListData pointer. Affected file silcd/protocol.c.
1002 * The normal server now does not remove the channel entry from
1003 the cache if the founder authentication data is set. It used
1004 to remove it if the founder was the last one on the channel on
1005 the server and left the channel. The auth data is saved and
1006 if the channel is re-joined later the old entry is used with
1007 the old auth data. Affected files silcd/command_reply.c and
1010 * Removed the `pkcs' field from the SilcIDListData structure
1011 in the server; it is not used. Affected file silcd/idlist.h.
1013 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Fixed packet processing on slow links. Partial packets were
1016 never re-processed because the incoming data buffer was cleared
1017 by the application. Application must not directly clear the
1018 sock->inbuf, the packet processing routines handle it. Fixed
1019 this in client library and in server.
1021 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * Fixed the WHOIS and IDENTIFY send reply function to really
1024 check whether to send list or just one entry. Affected file
1027 * Cleaned up the LEAVE command's channel key distribution. The
1028 affected file silcd/command.c.
1030 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1031 can enforce the channel mode as well. In that case the ID
1032 includes the ID of the server. The code now enforces the
1033 mode change if the router have different mode than the server.
1035 * The notify client operation with CMODE_CHANGE notify can now
1036 return NULL client_entry pointer if the CMODE was not changed
1037 by client. Application must check for this.
1039 * Added <Server ID> argument to INFO command to support server
1040 info fetching by Server ID.
1042 * Added silc_server_announce_get_channel_users to get assembled
1043 packets of channel users of the specified channel. Affected
1044 file silcd/server.[ch].
1046 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1047 was freed underneath the ID Cache.
1049 * Re-announce clients when the server received CHANNEL_CHANGE
1050 notify from the router. Affected file silcd/packet_send.c.
1052 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1055 crashed since it did not handle the fact that there is no cipher
1056 called "3" and didn't check the error condition. Now fixed.
1058 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1059 flag. It can be used to send message requests.
1061 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1063 * Implemented the RESTART command in the client.
1065 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1066 notice type messages. Added notice printing to the user
1069 * The channel keys are not re-generated if the channel's mode
1070 is PRIVKEY, ie private key on the channel exists. Affected
1071 files silcd/server.c and silcd/command.c.
1073 * Fixed a little bug in channel message delivery when channel
1074 private keys are set in the server. Affected file is
1075 silcd/packet_send.c.
1077 * Changed the setting on channel->on_channel = TRUE from the
1078 silc_client_save_channel_key to the JOIN command reply. The
1079 key payload is not received if the private channel key is set.
1080 Affected file lib/silcclient/command_reply.c and the
1081 lib/silcclient/client_channel.c.
1083 * When the CMODE_CHANGE notify is sent and the channel private
1084 key mode is removed the channel key must be re-generated in
1085 other cells as well. Added this support for the router in the
1086 silcd/packet_receive.c.
1088 * Added new local command NOTICE to send notice message on
1089 channel. Affected file silc/local_command.[ch].
1091 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1093 * Added new local command ME to the client. It is used to send
1094 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1095 some action. Affected file silc/local_command.[ch].
1097 * Changed channel_message and private_message client operations
1098 to deliver the message flags to the application. Added also
1099 the `flags' arguments to the silc_client_send_channel_message
1100 and silc_client_send_private_message functions. Affected file
1103 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * Redefined the Private Message Payload to support private message
1106 keys and to support the new private message flags. Updated
1107 the protocol specs. Flags makes it possible to have for example
1108 CTCP style messages.
1110 * Added new type SilcPrivateMessagePayload and defined an API
1111 for it in the lib/silcclient/silcprivate.[ch].
1113 * Tested private message private keys successfully. Tested the
1114 private message key set, unset and list commands with the new
1117 * Redefined the Channel Message Payload to include the channel
1118 message flags (equal with private message flags) to support
1119 for example CTCP style messages.
1121 * Defined some of the message (for channel and private message)
1122 flags. Updated the protocol specs and added the flags to the
1123 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1125 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1127 * Added SilcKeyAgreementStatus type to the key agreement routines
1128 to indicate the current status and error if one occured.
1129 The status types are defined in the lib/silcclient/silcapi.h.
1131 * Added new local command KEY that is used to set and unset private
1132 keys for channels, set and unset private keys for private messages
1133 with remote clients and to send key agreement requests and
1134 negotiate the key agreement protocol with remote client. The
1135 key agreement is supported only to negotiate private message keys,
1136 it currently cannot be used to negotiate private keys for channels,
1137 as it is not convenient for that purpose.
1139 * Fixed a minor pending callback setting bug in the function
1140 silc_client_get_client_by_id_resolve, now the function works.
1141 Affected file lib/silcclient/idlist.c.
1143 * Added function silc_net_get_local_port to get local bound
1144 port by socket. Added to lib/silcutil/silcnet.[ch].
1146 * Added `sockets' and `sockets_count' fields to the SilcClient
1147 object. They hold the sockets of the listenning sockets in
1148 the client. Listenning sockets may be for example the key
1149 agreement server. Affected file lib/silcclient/client.[ch].
1150 Added functions the silc_client_add_socket and the
1151 silc_client_del_socket. They are exported to the application
1154 * Added ~./silc/clientkeys to support other client's public keys.
1156 * Renamed verify_server_key client operation to verify_public_key
1157 and added one argument to indicate the type of the connection
1158 (server, client etc.).
1160 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1162 * Added silc_server_connection_auth_request to handle the
1163 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1164 silcd/packet_receive.[ch].
1166 * Added silc_server_send_connection_auth_request into the
1167 silcd/packet_send.c to send the connection auth request packet.
1169 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1172 * Fixed the public key authentication in responder side in the
1173 server. The `auth_data' pointer includes the SilcPublicKey
1174 not the path to the public key. Affected file silcd/protocol.c.
1176 * Implemented the public key authentication in the initiator side
1177 in the server. Affected file silcd/protocol.c.
1179 * Removed the [RedirectClient] config section from the server
1180 configuration. Is not needed and I don't want to implement it.
1182 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * Cleaned up the CMODE command in the server. It now works
1185 correctly and supports all the modes defined in the protocol.
1186 Affected file is silcd/command.c.
1188 * Added `hmac_name' field to the SilcChannelEntry in the server
1189 to hold the default HMAC of the channel. It can be set when
1190 creating the channel (with JOIN command). Affected files
1193 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1194 type to indicate the change of the current cipher and hmac
1195 on the channel. Client can safely ignore the <cipher> argument
1196 (if it chooses to do so) since the CHANNEL_KEY packet will
1197 force the channel key change anyway. The <hmac> argument is
1198 important since the client is responsible of setting the new
1199 HMAC and the hmac key into use.
1201 * Fixed the CMODE command in the client library as well.
1203 * Tested CMODE command in router environment successfully.
1205 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Show the version of the remote client (or server) when connecting
1208 to the server. It is logged to the log file. Affected file
1209 is silcd/protocol.c.
1211 * Fixed the KILLED notify handling in the client library. The
1212 client must be removed from all channels when receiving the
1215 Also, do not remove the client entry when giving the KILL
1216 command but when the KILLED notify is received.
1218 * Removed silc_idlist_find_client_by_nickname from the server.
1219 Not needed anymore. Affected files silcd/idlist.[ch].
1221 * Implemented the CHANNEL_CHANGE notify type handling to the
1222 server. Affected file silcd/server.c.
1226 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1228 * Added silc_server_send_notify_invite to send the INVITE
1229 notify between routers.
1231 * Implemented the INVITE command correctly to the server.
1233 * Implemented the INVITE notify type handling in the server.
1235 * Implemented the INVITE command to the client library and on the
1238 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1240 * Added function silc_server_get_client_resolve to find the
1241 client entry by ID from all ID lists and then resolve it
1242 (using WHOIS) if it cannot be found. Affected file is
1245 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1247 * Implemented the BAN command to the client library.
1249 * The JOIN command in the server now checks the invite list
1252 * Changed the silc_command_reply_payload_encode_va and the
1253 silc_command_payload_encode_va to support that if argument is
1254 NULL it ignores and checks the next argument. Affected file
1255 lib/silccore/silccommand.c.
1257 * Added silc_server_send_notify_ban to send the BAN notify
1258 type between routers.
1260 * Chaned the silc_notify_payload_encode to support that if
1261 argument is NULL it ignores and checks the next argument.
1262 Affected file lib/silccore/silcnotify.c.
1264 * Tested ban lists in router environment successfully.
1266 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Implemented BAN command to the server, in silcd/command.[ch].
1270 * Removed the BAN and INVITE_LIST modes from the CMODE command
1273 * Added function silc_string_match to regex match two strings.
1274 Affected files lib/silcutil/silcutil.[ch].
1276 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1278 * Redefined parts of the SilcChannelEntry in the server to support
1279 the new ban and invite lists.
1281 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1283 * Redefined the INVITE command. The same command can be used to
1284 invite individuals to the channel but also to manage the invite
1285 list of the channel (to add to and remove from the invite list).
1286 Updated the protocol specs.
1288 * Added new command SILC_COMMAND_BAN that can be used to manage
1289 the ban list of the channel. Updated the protocol specs.
1291 * Removed the channel modes: the SILC_CMODE_BAN and the
1292 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1293 in the CMODE command. The equivalent features are now available
1294 using INVITE and BAN commands. Updated the protocol specs.
1296 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1297 in the network about change in the current ban list. The notify
1298 type is not used by the client.
1300 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1301 support the invite lists.
1303 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1305 * Added new function silc_string_regexify that converts string
1306 including wildcard characters into regex string that can
1307 be used by the GNU regex library. Added into the file
1308 lib/silcutil/silcutil.[ch].
1310 Added silc_string_regex_combine to combine to regex strings
1311 into one so that they can be used as one regex string by
1312 the GNU regex library. Added into the file
1313 lib/silcutil/silcutil.[ch].
1315 Added silc_string_regex_match to match two strings. It returns
1316 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1318 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1320 * Imported GNU regex to the soruce tree into lib/contrib.
1321 Fixed some compiler warning from the regex.c.
1323 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1325 * Fixed MOTD command in the server to work in router environment.
1327 * Fixed the MOTD command in the client library to support
1328 the server argument in the command.
1330 * Added `nickname_len' argument to the silc_idlist_add_client
1331 in the server, as the `nickname' argument may be binary data
1334 * Added silc_idlist_get_channels to return all channels from
1337 * Implemented LIST command to the server. Affected file is
1340 * Implemented the LIST command to the client library and on the
1343 * Added [<user count>] argument to the LIST command reply.
1344 With private channels the user count is not shown.
1346 * Updated TODO and README.
1348 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1350 * The client entry's data.registered must be TRUE even with
1351 global client entry on global client list. The data.registered
1352 is used to check whether the client is anymore in the network,
1353 for example with WHOWAS command so it must be valid.
1355 * Fixed the WHOWAS command in the server. It now actually works
1356 in router environment. Added function into silcd/command_reply.c
1357 silc_server_command_reply_whowas_save.
1359 * Added silc_idlist_purge function to the silcd/idlist.c
1360 to periodically purge the ID Cache.
1362 * Fixed INFO command in the server. It works now in router
1363 environment. Added <server name> argument to the INFO command
1364 reply. Updated the protocol specs.
1366 * Fixed minor bug in silc_idcache_purge to not purge if the
1367 expire value is zero.
1369 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1370 they were buggy because of the WHOWAS information.
1372 * Fixed local command MSG to handle the async resolving of
1373 the remote client properly. It used to fail the first MSG.
1374 Affected file silc/local_command.c.
1376 * Added `data_len' field to SilcIDCache context.
1378 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * Update TODO. Todo in commands in the server.
1382 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1384 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1385 used by routers as broadcast packet to inform other routers
1386 about the changed user mode.
1388 Implemented the notify handling in the server. Affected file is
1389 silcd/packet_receive.c. Added the function
1390 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1392 * Added new generic Channel Payload and deprecated the New Channel
1393 Payload. The New Channel Payload is now the generic Channel
1396 * Added new argument `mode' to the silc_server_send_new_channel
1397 as it is required in the Channel Payload now.
1399 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1400 and created a new and real SilChannelPayload to represent the
1401 new generic Channel Payload. Implemented the encode/decode
1402 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1404 * Added silc_server_get_client_channel_list to return the list
1405 of channels the client has joined for WHOIS command reply.
1406 Affected file silcd/server.[ch].
1408 * Implemented the channel list sending in the WHOIS command reply
1409 in server and in the client.
1411 Implemented the channel list displaying on the user interface
1412 as well. Affected file silc/client_ops.c.
1414 * Added silc_channel_payload_parse_list to parse list of Channel
1415 Payloads. It returns SilcDList list of SilcChannelPayloads.
1416 Client for example can use this function to parse the list of
1417 channels it receives in the WHOIS command reply. The caller
1418 must free the list by calling silc_channel_payload_list_free.
1419 Affected files lib/silccore/silcchannel.[ch].
1421 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1423 * Added one new argument <user mode> to the WHOIS command reply
1424 to return the mode of the user in SILC. Updated the protocol
1427 Implemented it to the server and client.
1429 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1431 * Fixed the mode printing on the user interface on joining.
1432 Affected file silc/client_ops.c.
1434 * Implemented the UMODE command and user modes in general to the
1435 client library and to the user interface.
1437 * Implemented the UMODE command to the server.
1439 * The server now sends UNKNOWN_COMMAND error status if client sends
1440 unknown command. Affected file silcd/command.c.
1442 * All server commands now handle the command identifier the right
1443 way when sending the command reply to the client. The client can
1444 use to identify the command replies with the identifier.
1446 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1448 * Added silc_server_get_client_route to resolve the route to
1449 the client indicated by the client ID. Affected file is
1452 * Added silc_server_relay_packet as general function to relay
1453 packet to arbitrary destination. This deprecates functions
1454 like _send_private_message_key, _relay_notify etc. Affected
1455 file is silcd/packet_send.[ch].
1457 Removed silc_server_send_key_agreement,
1458 silc_server_send_private_message_key and
1459 silc_server_packet_relay_notify functions from the file
1460 silcd/packet_send.[ch].
1464 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1465 server. Affected file silcd/packet_receive.[ch].
1467 * Implemented the KILL command to the client. Implemented the
1468 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1469 Affected files lib/silcclient/command[_reply].c and
1470 lib/silcclient/client_notify.c. Implemented the KILL notify
1471 printing in the user inteface.
1473 * Fixed a lot silc_parse_nick memory leaks from the client
1474 library in the file lib/silcclient/command.c.
1476 * Changed the silc_server_send_notify_on_channels's `sender'
1477 argument from SilcSocketConnection to SilcClientEntry to
1478 check the sender as entry and not as connection object and not
1479 to send to the client provided as argument. The affected file
1480 is silcd/packet_send.[ch].
1482 * The notify packets that are destined directly to the client used
1483 to not to be processed by the server. Now changed that and the
1484 server processes all notify packets. After relaying the packet
1485 to the client the notify packet is processed in the server.
1487 * The silc_server_free_client_data now checks whether there is
1488 pending outgoing traffic for the client and purges the data to
1489 the network before removing the client entry.
1491 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1493 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1494 an client is killed from the SILC Network. Updated the protocol
1497 Added new function silc_server_send_notify_killed to the
1498 silcd/packet_send.[ch].
1500 * Added function silc_server_packet_relay_notify to relay notify
1501 packets that are destined directly to a client. In this case
1502 the server does not process the notify packets but merely relays
1503 it to the client. Affected file silcd/packet_send.[ch].
1505 Added also silc_server_packet_process_relay_notify to check
1506 whereto relay the notify. Affected file is
1507 silcd/packet_receive.[ch].
1509 * Implemented the KILL command to the server.
1513 * Added the backup schema desgined last fall to the protocol
1514 specs for everyone to see. The specification is in the
1515 *-spec-xx.txt draft and the packet type definitions for the
1516 backup routers is in *-pp-xx.txt draft. Thusly, added also
1517 new packet type SILC_PACKET_CELL_ROUTERS.
1519 * A big security problem in the implementation discovered. The
1520 signoff of an client did not cause new channel key generation
1521 which it of course should've done. The channel keys must be
1522 always re-generated when client leaves (or signoffs) the channel.
1523 The silc_server_remove_from_channels funtion now handles
1524 the channel key re-generation.
1526 * Added `sender' argument to the silc_server_send_notify_on_channels
1527 to not to send the client provided as argument. Affected file
1528 silcd/packet_send.[ch].
1530 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1532 * Implemented OPER and SILCOPER commands into the server and
1535 * Added silc_auth_verify and silc_auth_verify_data to verify
1536 the authentication directly from the authentication payload.
1537 It supports verifying both passphrase and public key based
1538 authentication. Affected file lib/silccore/silcauth.[ch].
1540 * Added `hash' field to the SilcIDListData structure. It is the
1541 hash negotiated in the SKE protocol. Affected file is
1544 * Slight redesigning of the SilcAuthPayload handling routines.
1545 Do not send SilcPKCS but SilcPublicKey as argument.
1547 * Implemented the public key authentication support to the
1548 serverconfig. The public key is loaded from the provided path
1549 and saved as authentication data to void * pointer. Thus,
1550 changed the unsigned char *auth_data to void *auth_data;
1552 * Fixed SHUTDOWN command to send the reply before the server
1553 is shutdown. :) Affected file silcd/command.c.
1555 * Fixed fatal bug in CONNECT command. The hostname was invalid
1556 memory and server crashed. Affected file silcd/command.c.
1558 * Fixed fatal bug in CLOSE command. The server_entry became
1559 invalid but was referenced later in the command. Affected file
1562 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1564 * Fixed fatal bug in failure packet handling. Server ignored
1565 the failure and thus crashed when it came.
1569 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1571 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1572 that the command may be executed only once in (about) 2 seconds.
1573 The old SILC_CF_LAG flag is same but allows command bursts up
1574 to five before limiting.
1576 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1577 server code. Various commands now includes the CF_LAG_STRICT
1578 flag to disallow any kind of miss-use of the command.
1580 * Fixed the silc_buffer_unformat to not to allocate any data
1581 if the length of the data is zero. It used to allocate the
1582 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1584 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Changed the format of AdminConnection configuration section
1587 in the server. Added username of the admin to the format.
1588 Affected files silcd/serverconfig.[ch].
1590 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1591 to return admin configuration data by host, username and/or
1594 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1596 * Implemented WHOWAS command to the server. Added the functions:
1598 silc_server_command_whowas_parse,
1599 silc_server_command_whowas_send_reply,
1600 silc_server_command_whowas_from_client and
1601 silc_server_command_whowas_from_server
1603 * Added <Client ID> argument to the WHOWAS command reply. Updated
1604 the protocol specs accordingly.
1606 * Implemented WHOWAS command and command_reply to the client
1609 Implemented the WHOWAS printing on the user interface.
1611 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1613 * Added new argument to the WHOWAS command reply, the real name.
1614 It is an optional argument. Updated the protocol specs.
1616 * Added SilcIDCacheDestructor callback that is registered when
1617 the SilcIDCache is allocated. The callback is called when
1618 an cache entry in the ID Cache expires, or is purged from the
1619 cache. Added into lib/silccore/idcache.[ch].
1621 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1622 to destruct the client entries when the cache entry expires.
1623 Other ID Cache's in server and in the client library ignores
1626 * If the ID Cache entry's `expire' field is zero then the entry
1627 never expires. Added boolean `expire' argument to the
1628 silc_idcache_add function in the lib/silccore/idcache.[ch].
1629 If it is TRUE the default expiry value is used.
1631 * Added silc_server_free_client_data_timeout that is registered
1632 when client disconnects. By default for 5 minutes we preserve
1633 the client entry for history - for WHOWAS command.
1635 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1637 * Added support to the server to enforce that commands are not
1638 executed more than once in 2 seconds. If server receives
1639 commands from client more frequently, timeout is registered
1640 to process the commands. Affected file silcd/command.c.
1641 Added new function silc_server_command_process_timeout.
1643 * Changed NICK_NOTIFY handling in client library to check that
1644 if the client's nickname was changed, so there is no need to
1645 resolve anything from the server.
1647 * Removed error printing from the WHOIS and IDENTIFY commands.
1648 If error occurs then it is ignored silently in the client library.
1649 The application, however, may map the received error to
1650 human readable error string. The application currently maps
1651 the NO_SUCH_NICKNAME error to string.
1653 * Made the command status message public to the application. Moved
1654 them from lib/silcclient/command_reply.c to
1655 lib/silcclient/command_reply.h. The application can map the
1656 received command status to the string with the
1657 silc_client_command_status_message function.
1659 * Added check to the server to check that client's ID is same
1660 as the Source ID in the packet the client sent. They must
1663 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1665 * Added dist-bzip hook to the Makefile.am to make bzip2
1666 compressed distributions.
1668 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * Server now enforces the maximum length for the nickname and
1671 the channel as protocol specification dictates. 128 bytes for
1672 nickname and 256 bytes for channel name.
1674 * Moved the WHOIS printing to the application. The client libary
1675 does not print out the WHOIS information anymore, the application
1676 must do it. Renamed silc_client_command_reply_whois_print to
1677 the silc_client_command_reply_whois_save.
1679 The client's idle time is also sent to the application now, and
1680 the idle is shown on screen.
1682 * Added silc_client_command_reply_identify_save to save the
1683 received IDENTIFY entries.
1685 * Do not check for channel private keys in message sending and
1686 reception if the channel does not have the PRIVKEY mode set.
1687 Affected file lib/silclient/client_channel.c.
1689 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1691 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1692 just surfaced after chaning the JOIN procedure.
1694 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1696 * Added silc_client_get_clients_by_list to get client entries
1697 from Client ID list, that is returned for example by JOIN
1698 and USERS command replies. The application should use this
1699 function for example when JOIN command reply is received to
1700 resolve the clients already on the channel (library does not
1701 do that anymore as USERS command reply is not used in the JOIN
1702 procedure anymore). Affected files lib/silcclient/silcapi.h and
1703 lib/silcclient/idlist.c.
1705 * JOIN command reply and USERS command reply returns now SilcBuffer
1706 pointers instead of unsigned char pointers when returning
1707 the client list and mode list.
1709 * Added <Client ID> argument to the JOIN command reply, mainly
1710 for the server to identify for which client the command was
1711 originally sent. Updated protocol specs accordingly.
1713 * Added SilcDlist private_key pointer to the SilcChannelEntry
1714 in the client to support the channel private keys. Affected
1715 file is lib/silcclient/idlist.h.
1717 * Added SilcChannelPrivateKey argument to the function
1718 silc_client_send_channel_message so that application can choose
1719 to use specific private ke if it wants to. If it is not provided,
1720 the normal channel key is used, unless private keys are set.
1721 In this case the first (key that was added first) is used
1722 as the encryption key.
1724 * Implemented the support for channel private key handling.
1725 Implemented the following functions:
1727 silc_client_add_channel_private_key,
1728 silc_client_del_channel_private_keys,
1729 silc_client_del_channel_private_key,
1730 silc_client_list_channel_private_keys and
1731 silc_client_free_channel_private_keys
1733 Affected file lib/silcclient/client_channel.c.
1735 * Added the support for the private keys in the channel message
1736 sending and encryption and in the message reception and
1737 decryption. Affected funtions are
1738 silc_client_send_channel_message and silc_client_channel_message.
1740 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1742 * Added SKE's key verify callback to the client library's
1743 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1745 * Removed the statement that server (or router) must send USERS
1746 command reply when joining to the channel so that the client
1747 knows who are on the channel. Instead, the client list and
1748 client's mode list is now sent in the JOIN command reply to the
1749 client who joined channel. This is better solution.
1751 * Added function silc_server_get_users_on_channel and function
1752 silc_server_save_users_on_channel to the silcd/server.[ch].
1754 * Removed function silc_server_command_send_users from the
1757 * Do not show topic on the client library anymore. The topic is
1758 sent in the command reply notify to the application and the
1759 application must show the topic now.
1761 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1763 * Added client searching by nickname hash into the IDENTIFY and
1764 WHOIS commands in the server as they were clearly missing from
1765 them. Affected file is silcd/command.c.
1767 * Fixed a bug in private message receiving in the client library.
1768 The remote ID was freed and it wasn't supposed, now it is
1771 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1773 * Minor fix to the channel payload; allocate the data area, as it
1774 needs to be of specific length.
1776 * If the key agreement port is zero then the operating
1777 system will define the bound port. Affected files are
1778 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1780 * Added new function silc_channel_payload_decrypt into the file
1781 lib/silccore/silcchannel.[ch].
1783 * Moved the channel message etc, check from silc_packet_decrypt
1784 to applications. The library calls now a generic
1785 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1786 when the packet is either normal or special. This was done to
1787 allow more wide range of checking that was not allowed when
1788 the code was in library. Now applications can do virtually any
1789 checks to the packet and return to the library the decision how
1790 the packet should be processed. Affected files are
1791 lib/silccore/silcpacket.[ch].
1793 Added silc_server_packet_decrypt_check to the server and
1794 silc_client_packet_decrypt_check to the client library.
1796 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1797 to send with specified source and destination information.
1799 * Channel message delivery between routers was broken after the
1800 channel key distribution was fixed earlier. The channel key
1801 was used be to distributed to other routers as well which is not
1802 allowed by the protocol. Now this is fixed and channel keys
1803 really are cell specific and the channel message delivery between
1804 routers comply with the protocol specification.
1806 * Fixed various commands in server to check also the global list
1807 for the channel entry and not just the local list. The affected
1808 file silcd/command.c.
1810 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1812 * Added assert()s to buffer formatting and unformatting routines
1813 to assert (if --enable-debug) when error occurs. Affected
1814 file: lib/silcutil/silcbuffmt.c.
1816 * Changed to auto-reconnect to check whether the remote host is
1817 router and register the re-connect timeout if it is. It used
1818 to check that whether we are normal server, but router must do
1819 auto-reconnect with another router as well. Affected file
1822 * Removed the [<key len>] option from CMODE command as the cipher
1823 name decides the key length, nowadays. See the defined ciphers
1824 from the protocol specification.
1826 * Added [<hmac>] option to the CMODE command to define the HMAC
1827 for the channel. Added SILC_CMODE_HMAC channel mode.
1829 * Added [<hmac>] option for the JOIN command so that user can
1830 select which HMAC is used to compute the MACs of the channel
1833 * Added Hmac field to the Channel Message Payload. The integrity
1834 of plaintext channel messages are now protected by computing
1835 MAC of the message and attaching the MAC to the payload. The
1836 MAC is encrypted. Now, it is clear that this causes some
1837 overhead to the size of the packet but rationale for this is that
1838 now the receiver can verify whether the channel message decrypted
1839 correctly and also when private keys are set for the channel the
1840 receiver can decrypt the packet with several keys and check from
1841 the MAC which key decrypted the message correctly.
1843 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1844 lib/silccrypt/silccipher.[ch].
1846 * Added silc_hash_len to return the digest length into the
1847 lib/silcrypt/silchash.[ch].
1849 * Rewrote parts of Silc Channel Payload interface in the
1850 lib/silccore/silcchannel.[ch]. The encode function now also
1851 encrypts the packet and parse function decrypts it.
1853 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * Fixed a minor formatting bug in the SKE's key material processing.
1856 It actually might have processed the keys wrong way resulting
1859 * Redefined the mandatory HMAC algorithms and added new algorithms.
1860 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1861 and hmac-md5 truncated to 96 bits. The mandatory is now
1862 hmac-sha1-96. Rest are optional (including the one that used
1863 to be mandatory). Rationale for this is that the truncated HMAC
1864 length is sufficient from security point of view and can actually
1865 make the attack against the HMAC harder. Also, the truncated
1866 HMAC causes less overhead to the packets. See the RFC2104 for
1869 * Added new [hmac] configuration section. The SKE used to use
1870 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1871 is of course wrong. The official names that must be proposed in
1872 the SKE are the ones defined in the protocol specification
1873 (hmac-sha1-96 for example). The user can configure any hmac
1874 using any hash function configured in the [hash] section. At
1875 least, the mandatory must be configured.
1877 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1879 * Added HMAC list to the SKE proposal list. It has now both
1880 hash algorithm list and HMAC list. This makes the protocol
1881 incompatible with previous versions. The SKE now seems to work
1882 the way it is supposed to work, for the first time actually.
1884 * Defined plain Hash algorithms to the protocol specification.
1887 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1889 * Implemented support for key agreement packets into the server.
1890 Added functions silc_server_key_agreement and
1891 silc_server_send_key_agreement. Other than these functions,
1892 server has nothing to do with this packet.
1894 * Added support for private message key packets into the server.
1895 Added functions silc_server_private_message_key and
1896 silc_server_send_private_message_key.
1900 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1901 called in the protocol's final callback instead in the END
1902 protocol state. This makes a little more sense and in the same
1903 time in client we can use the same protocol routines for normal
1904 key exchange and to key agreement packet handling as well.
1906 * Added to both client's and server's KE protocol context the
1907 SilcSKEKeyMaterial pointer to save the key material. We will
1908 bring the key material to the protocol's final callback by doing
1909 this. The final callback must free the key material.
1911 * Added SKE's packet_send callback into client's KE protocol
1912 context so that the caller can choose what packet sending function
1913 is used. This way we can use different packet sending when
1914 doing normal SKE when doing key agreement packet handling (in
1915 the key agreement packet handling we do not want to encrypt
1918 * Implemented the responder side of the key agreement routines
1919 in the client. The client can now bind to specified port and
1920 accept incoming key negotiation. The key material is passed
1921 to the application after the protocol is over.
1923 * Implemented the processing of incoming Key Agreement packet
1924 in the client. Added function silc_client_key_agreement to
1927 * Implemented the intiator side of the key agreement routines
1928 in the client. The client can now initiate key agreement with
1929 another remote client. The key material is passed to the
1930 application after the protocol is over.
1932 * Created client_keyagr.c to include all the key agreement
1935 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1936 SILC_TASK_CALLBACK except that it is not static.
1938 * Created client_notify.c and moved the Notify packet handling
1939 from the client.[ch] into that file.
1941 * Created client_prvmsg.c and moved all private message and
1942 private message key routines from the client.[ch] into that file.
1944 * Create client_channel.c and moved all channel message and
1945 channel private key routines from the client.[ch] into that file.
1947 * Changed silc_client_get_client_by_id_resolve to resolve with
1948 WHOIS command instead of IDENTIFY command, in the file
1949 lib/silclient/idlist.c.
1951 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1953 * Implemented the SKE's responder side to the Client library.
1955 * When FAILURE is received to the protocol do not trust it
1956 blindly. Register a timeout to wait whether the remote closes
1957 the connection as it should do it, only after that process the
1958 actual failure. This was changed to both client and server.
1960 * Added client_internal.h to include some of the structures
1961 there instead of client.h in lib/silcclient/.
1963 * Added function silc_task_unregister_by_callback to unregister
1964 timeouts by the callback function.
1966 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1968 * Some "Incomplete WHOIS info" errors has been appearing on the
1969 log files. Took away the entry->userinfo check from WHOIS
1970 reply sending. The entry->userinfo is now " " if client did not
1971 provide one. I thought this was fixed earlier but something
1972 is wrong still. Let's see if the error still appears.
1974 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1976 * Fixed a minor bug in the login when the channel key is
1977 re-generated in the server. It used to generate the key in
1978 wrong order and thus caused problems in the channel traffic.
1980 * Fixed a minor bug in channel key distsribution after
1981 KICK command. The key was not sent to the router even though
1984 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1986 * Added silc_ske_process_key_material_data as generic routine
1987 to process any key material as the SILC protocol dictates. The
1988 function is used by the actual SKE library but can be used by
1989 applications as well. This relates to the private message keys
1990 and the channel private keys since they must be processed the
1991 same way the normal SILC session keys. The protocol dictates
1992 this. Affected files: lib/silcske/silcske.[ch].
1994 Added also silc_ske_free_key_material to free the
1995 SilcSKEKeyMaterial structure.
1997 * Defined silc_cipher_set_key function to set the key for
1998 cipher without using the object's method function. The affected
1999 files: lib/silccrypt/silccipher.[ch].
2001 * Implemented silc silc_client_add_private_message_key,
2002 silc_client_add_private_message_key_ske,
2003 silc_client_del_private_message_key,
2004 silc_client_list_private_message_keys and
2005 silc_client_free_private_message_keys functions in the
2008 Added functions silc_client_send_private_message_key to send
2009 the Private Message Key payload and silc_client_private_message_key
2010 to handle incoming Private Message Key payload.
2012 * Added Cipher field to the Private Message Key payload to set
2013 the cipher to be used. If ignored, the default cipher defined
2014 in the SILC protocol (aes-256-cbc) is used.
2016 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2018 * Removed lib/silcclient/ops.h file.
2020 Redefined parts of the SILC Client Library API. Created new
2021 file silcapi.h that deprecates the ops.h file and defines the
2022 published Client Library API. Defined also private message key
2023 API and channel private key API into the file.
2025 This is the file that the application must include from the
2026 SILC Client Library. Other files need not be included by
2027 the application anymore.
2029 * Added new key_agreement client operation callback and also
2030 defined the Key Agreement library API for the application.
2032 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2034 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2035 is used by clients to request key negotiation between another
2036 client in the SILC network. If the negotiation is started it
2037 is performed using the SKE protocol. The result of the
2038 negotiation, the secret key material, can be used for example
2039 as private message key.
2041 Implemented the Key Agreement payload into the files
2042 lib/silccore/silauth.[ch].
2044 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2046 * Redefined ciphers for the SILC protocol. Added some new ciphers
2047 and defined the key lengths for the algorithms. Changed the
2048 code accordingly. The default key length is now 256 bits.
2050 * Fixed SKE key distribution function silc_ske_process_key_material
2051 when the key length is more than 128 bits. The default key
2052 length in SILC is now 256 bits.
2054 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2055 to indicate unsupported algorithm.
2057 * Renamed rijndael.c to aes.c and all functions as well.
2059 * Fixed a long standing channel key setting bug in client library.
2060 Weird that it has never surfaced before.
2062 * Fixed bug in channel deletion. If the entire channel is removed
2063 then it must also delete the references of the channel entry
2064 from the client's channel list as the client's channel entry and
2065 the channel's client entry share same memory.
2067 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2069 * Implemented CONNECT and SHUTDOWN commands in the client.
2071 * Implemented CLOSE command to the client.
2073 * Added the function silc_idlist_find_server_by_name into the
2074 files silcd/idlist.[ch].
2076 Added the function silc_idlist_find_server_by_conn into the
2077 files silcd/idlist.[ch].
2079 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * DIE command was renamed to SHUTDOWN. Updated the both code
2084 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2085 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2087 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2090 * Added function silc_server_create_connection function to create
2091 connection to remote router. My server implementation actually
2092 does not allow router to connect to normal server (it expects
2093 that normal server always initiates the connection to the router)
2094 so the CONNECT command is only good for connecting to another
2097 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2100 or some other client was kicked from the channel.
2102 Implemented the handling of the notify type to both client
2105 Implemented silc_server_send_notify_kicked to send the KICKED
2106 notify. It is used to send it to the server's primary router.
2108 * Implemented the KICK command into server and client.
2110 * Added `query' argument to the silc_idlist_get_client function
2111 to indicate whether to query the client from server or not if
2114 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2115 to indicate that the client is not channel founder.
2119 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2121 * Removed the rng context from SilcPacketContext structure and
2122 changed that the packet routine uses the Global RNG API.
2124 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2126 * Added support for quit message that client can "leave" on the
2127 channel when it quits the SILC. It is ditributed inside the
2128 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2130 Added silc_server_free_client_data that will take the
2131 signoff message as argument.
2133 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2135 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2137 * Updated parts of the protocol specification to keep it up
2140 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2142 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2143 payloads in one packet.
2145 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2146 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2147 use now the new List flag.
2149 * Also deprecated the following packet types: REPLACE_ID,
2150 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2152 * Added list support for Notify packet in server.
2154 * Added silc_server_send_notify_channel_change to send the
2155 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2156 the silc_server_send_replace_id.
2158 * Added silc_server_send_notify_nick_change to send the
2159 NICK_CHANGE notify type. Deprecates the function
2160 silc_server_send_replace_id.
2162 * Added silc_server_send_notify_join to send the JOIN notify type.
2163 Deprecates the function silc_server_send_new_channel_user.
2165 * Added silc_server_send_notify_leave to send LEAVE notify type.
2166 Deprecates the function silc_server_send_remove_channel_user.
2168 * Added silc_server_send_notify_cmode and
2169 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2170 types. Deprecates the silc_server_send_set_mode function.
2172 * Added SERVER_SIGNOFF notify type to indicate that server has
2173 quit. This means that all clients on the channel from that
2174 server will drop. This can be also used when netsplit happens.
2176 Deprecated REMOVE_ID packet type since it is not needed anymore
2179 Added silc_server_send_notify_server_signoff to send the
2180 SERVER_SIGNOFF notify type. Deprecates the function
2181 silc_server_send_remove_id.
2183 Added also silc_server_send_notify_signoff to send the
2184 SIGNOFF notify type.
2186 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2187 SILC protocol from this day on. Changed the protocol
2188 specification as well.
2190 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2191 notify type. It is used between routers to notify about
2192 topic changes on a channel.
2194 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2197 * Partly updated the protocol specification to comply with the
2198 changes now made. It is still though a bit outdated.
2200 * The JOIN notify type now takes one extra argument <Channel ID>.
2201 The packet used to be destined to the channel but now the
2202 JOIN type may be sent as list thus it is impossible to
2203 destine it to any specific channel. By adding this argument
2204 it is again possible.
2206 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2208 * Added CREDITS file. The CHANGES and CREDITS file will appear
2209 in the distribution as well.
2211 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2213 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2214 types in the server's silcd/packet_receive.c.
2216 * Implemented CMODE and CUMODE to work in router environment.
2218 * Fixed minor encoding and decoding buglet from the
2219 lib/silccore/silcmode.c.
2221 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2224 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2226 * Changed all SilcConfigServer* and silc_config_server* to
2227 SilcServerConfig* and silc_server_config*, respectively.
2230 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2232 * Associated the ID (client or server ID) to the Authentication
2233 Payload to avoid any possibility of forging. Updated the
2234 protocol specification and the code accordingly.
2236 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2238 * The RSA key length is now save to the RsaKey context in the
2239 key generation process in lib/silccrypt/rsa.c. The key length
2240 is now used to figure out the maximum size of the block allowed
2241 to be encrypted/signed.
2243 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2244 is equivalent to the silc_mp_mp2bin but does not allocate any
2247 * Changed silc_mp_mp2bin API to take length argument. If it is
2248 non-zero then the buffer is allocated that large. If zero, then
2249 the size is approximated using silc_mp_sizeinbase, which however
2252 * Created Global RNG API which is global RNG that application can
2253 initialize. After initializing, any routine anywhere in the
2254 code (including library) can use RNG without allocating a new
2255 RNG object. This was done to allow this sort of use of the
2256 RNG in code that has no chance to allocate RNG object. All
2257 applications currently allocate this and many routines in the
2258 library use this. Affected file lib/silccrypt/silcrng.[ch].
2260 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2261 it to use the Global RNG API.
2263 * Defined Authentication Payload into protocol specification that
2264 is used during SILC session to authenticate entities. It is
2265 used for example by client to authenticate itself to the server
2266 to obtain server operator privileges.
2268 Implemented this payload into the lib/silccore/silcauth.[ch].
2269 Implemented also routines for public key based authentication
2270 as the new protocol specification dictates.
2272 Moved definitions of different authentication methods from
2273 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2275 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2276 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2277 silc_pkcs_verify_with_hash functions into the file
2278 lib/silccrypt/silcpkcs.[ch].
2280 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * The client entry's userinfo pointer must be always valid.
2283 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2284 will fail since it requires the userinfo. Now, the userinfo
2285 is allocated as "" if actual userinfo does not exist. Actually,
2286 it must exist and it is totally Ok to drop client connections
2287 that does not announce the userinfo. However, we will make
2288 this workaround for now.
2290 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2291 to return the remote port by socket.
2293 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2295 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2296 SILC_SERVER_PENDING_EXEC and added an new macro
2297 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2298 data or when error occurs while processing the pending command.
2300 Added new argument `destructor' into silc_server_command_pending
2301 and to the SilcServerCommandPending object. This destructor is
2302 now called after calling the pending callback or if error occurs
2303 immediately. If error occurs the actual pending callback won't
2304 be called at all - only the destructor. The destructor may be
2305 NULL if destructor is not needed.
2307 All this applies for client library code as well. Similar
2308 changes were made there as well for the pending commands.
2310 In the client, the application must now allocate the
2311 SilcClientCommandContext with the silc_client_command_alloc
2314 * Added reference counter to the SilcServerCommandContext. Added
2315 function silc_server_command_alloc and silc_server_command_dup
2318 Same type of functions added to the client library for the same
2321 * Removed the cmd_ident from IDListData away since it is now
2322 global for all connections. It is the command identifier used
2323 in command sending and with pending commands. The affected file
2326 * Added reference counter to the SilcSocketConnection objecet to
2327 indicate the usage count of the object. The object won't be
2328 freed untill the reference counter hits zero. Currently only
2329 server uses this, and client ignores it. The client must be
2330 set to use this too later. The affected files are
2331 lib/silccore/silcsockconn.[ch]. Added also the function
2332 silc_socket_dup to increase the reference counter.
2334 This was mainly added because it is possible that the socket
2335 is removed underneath of pending command or other async
2336 operation. Now it won't be free'd and proper DISCONNECTING
2337 flags, etc. can be set to avoid sending data to connection that
2338 is not valid anymore.
2340 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2341 the connection. After that it sets SILC_SET_DISCONNECTED.
2342 It is, however, possible that the socket data is not still freed.
2343 The silc_server_packet_process now checks that data is not
2344 read or written to connection that is DISCONNECTED. The socket
2345 get's freed when the reference counter hits zero.
2347 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2349 * Changed the client operation API: channel_message operation's
2350 `sender' is now the client entry of the sender, not the nickname
2351 and the `channel' is the channel entry, not the channel name.
2353 In the private_message operation the `sender' is now also the
2354 client entry of the sender not the nickname.
2356 Affected file is lib/silcclient/ops.h and all applications
2357 using the client operations.
2359 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2361 * Moved the calling of ops->connect() from connect_to_server_final
2362 into receive_new_id functin since that is the point when the
2363 client is actually allowed to send traffic to network. The
2364 affected file is lib/silcclient/client.c.
2366 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2368 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2369 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2370 (if needs broadcasting) instead of broadcasting the packets one
2371 by one which would make a burst in the network traffic.
2373 * Added `broadcast' argument to the functions in silcd/server.[ch]
2374 silc_server_create_new_channel[_with_id] to indicate whether
2375 to send New Channel packet to primary router.
2377 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2379 * Added new function into the silcd/server.[ch] files:
2380 silc_server_create_new_channel_with_id to create new channel with
2381 already existing Channel ID.
2383 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2384 lib/silccore/silcpacket.h. This packet is used t send list of
2385 Set Mode payloads inside one packet. Server uses this to set
2386 the modes for the channels and clients on those channels, that it
2387 announced to the router when it connected to it. The protocol
2388 specification has been updated accordingly.
2390 * The silc_server_new_channel did not handle the packet coming
2391 from normal server as it normally does not send that. However,
2392 when it announces its channels it does send it. Implemented
2393 the support for that.
2395 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2396 into the file lib/silccore/id.h.
2398 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2400 * Fixed memory leaks in the functions silc_idlist_del_client,
2401 silc_idlist_del_channel and silc_idlist_del_server in the file
2402 silcd/idlist.c. All of those leaked like a sieve.
2404 * Fixed some small memory leaks in the client's function
2405 silc_client_notify_by_server.
2407 * Added functions into silcd/server.c: silc_server_announce_clients,
2408 silc_server_announce_channels and silc_server_announce_server.
2409 These functions are used by normal and router server to announce
2410 to its primary router about clients, channels and servers (when
2411 router) that we own. This is done after we've connected to the
2414 These functions effectively implements the following packet types:
2415 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2416 and SILC_PACKET_NEW_ID_LIST.
2418 * Added new functions into the silcd/packet_receive.[ch]:
2419 silc_server_new_id_list, silc_server_new_channel_list and
2420 silc_server_new_channel_user_list to handle the incoming
2421 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2423 * Added support of changing Channel ID in the function
2424 silc_server_replace_id. If the server that announces a channel
2425 to the router already exists in the router (with same name but
2426 with different Channel ID), router is responsible to send
2427 Replace ID packet to the server and force the server to change
2428 the Channel ID to the one router has.
2430 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2431 client that the Channel ID has been changed by the router. The
2432 normal server sends this to the client. Client must start using
2433 the new Channel ID as the channel's ID.
2435 Implemented handling of this new type into lib/silcclient/client.c
2436 into the function silc_client_notify_by_server.
2438 * Added new function silc_idlist_replace_channel_id into the files
2439 silcd/idlist.[ch] to replace the Channel ID.
2441 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2443 * Call silc_server_command_identify_check always when processing
2444 the IDENTIFY command in silcd/command.c
2446 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2449 send keepalive packets. The packet can be sent by clients,
2450 servers and routers.
2452 Added function silc_socket_set_heartbeat into the file
2453 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2454 If not set, the heartbeat is not performed. The actual
2455 heartbeat is implemented in the low level socket connection
2456 library. However, application is responsible of actually
2459 Added silc_server_send_heartbeat to send the actual heartbeat
2460 packet into silcd/packet_send.[ch]. Server now performs
2461 keepalive with all connections.
2463 * Added silc_task_get_first function into lib/silcutil/silctask.c
2464 to return the timeout task with shortest timeout. There was a bug
2465 in task unregistration that caused problems. TODO has been
2466 updated to include that task system must be rewritten.
2468 * The client library will now resolve the client information when
2469 receiving JOIN notify from server for client that we know but
2470 have incomplete information.
2472 * Rewrote parts of silc_server_remove_from_channels and
2473 silc_server_remove_from_one_channel as they did not remove the
2474 channel in some circumstances even though they should've.
2476 * Encryption problem encountered in server:
2478 The LEAVE command used to send the Channel Key packet to the
2479 router immediately after generating it. However, the code
2480 had earlier sent Remove Channel user packet but not immediately,
2481 ie. it was put to queue. The order of packets in the router
2482 was that Channel Key packet was first and Remove Channel User
2483 packet was second, even though they were encrypted in the
2484 reverse order. For this reason, MAC check failed. Now, this
2485 is fixed by not sending the Channel Key packet immediately but
2486 putting it to queue. However, this is more fundamental problem:
2487 packets that are in queue should actually not be encrypted
2488 because packets that are sent immediately gets encrypted
2489 actually with wrong IV (and thus MAC check fails). So, packets
2490 that are in queue should be encrypted when they are sent to
2491 the wire and not when they put to the queue.
2493 However, the problem is that the current system has not been
2494 designed to work that way. Instead, the packet is encrypted
2495 as soon as possible and left to the queue. The queue is then
2496 just purged into wire. There won't be any fixes for this
2497 any time soon. So, the current semantic for packet sending
2500 o If you send packet to remote host and do not force the send
2501 (the packet will be in queue) then all subsequent packets to the
2502 same remote host must also be put to the queue. Only after the
2503 queue has been purged is it safe again to force the packet
2506 o If you send all packets immediately then it safe to send
2507 any of subsequent packets through the queue, however, after
2508 the first packet is put to queue then any subsequent packets
2509 must also be put to the queue.
2511 Follow these rules and everything works fine.
2513 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2515 * Added new function silc_server_remove_clients_by_server to
2516 remove all client entries from ID list when the server connection
2517 is lost. In this case it is also important to invalidate all
2518 client entires as they hold the invalid server entry. This
2519 fixes fatal bug when server has lost connection and will reconnect
2522 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Made some sanity checks to silc_server_daemonise like to check
2525 whether the requested user and group actually exists.
2527 * Added sanity check to SKE's silc_ske_responder_finish to check
2528 that the public and private key actually is valid.
2530 * Invalidate the client's nickname when receiving Replace ID
2531 packet and the Client ID is being replaced. This means that the
2532 server will query the nickname if someone needs it (client)
2535 * Sort the ID Cache in client library when the ID Cache data
2536 has changed (needs sorting).
2538 * Do not allow for SILC client to create several connections to
2539 several servers. The client does not support windows right now
2540 and generating multiple connections causes weird behaviour.
2542 Irssi-silc client does support windows and can handle several
2543 connections without problems, see: www.irssi.org and SILC plugin.
2545 * Fixed some places where client was added to the IDList. The
2546 rule of thumb is following (in order to get everything right):
2547 If the client is directly connected local client then the
2548 `connection' argument must be set and `router' argument must be
2549 NULL to silc_idlist_add_client function. If the client is not
2550 directly connected client then the `router' argument must
2551 bet set and the `connection' argument must be NULL to the
2552 silc_idlist_add_client function.
2554 * The funtion silc_server_packet_send_local_channel actually did
2555 not check whether the client was locally connected or not. It
2556 does that now. Fixed a bug related to LEAVE command.
2558 * Fixed Remove Channel User payload parsing bug in server's
2559 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2561 * The server's silc_server_save_channel_key now checks also the
2562 global ID list for the channel as it might not be in the local
2563 list. Fixed a bug related to LEAVE command.
2565 * Is this the end of the [<unknown>] buglet that has been lurking
2566 around for a long time? A little for loop fix in server's
2567 silc_server_command_whois_parse that is used by both IDENTIFY
2568 and WHOIS command. At least, this was a clear bug and a cause
2569 of one type of [<unknown>] buglet.
2571 * WHOIS and IDENTIFY commands call the function
2572 silc_server_command_[whois/identify]_check function even if
2573 we are not router server.
2575 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Added --with-gmp configuration option. If set the GMP
2578 is always compiled in the SILC source tree. If not set then
2579 it is checked whether the system has the GMP3 installed. If
2580 it has then the GMP won't be compiled (the system's headers
2581 and library is used), if it doesn't have it then the GMP is
2582 compiled in the SILC source tree.
2584 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Changed RSA private exponent generation to what PKCS #1
2587 suggests. We try to find the smallest possible d by doing
2588 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2589 not security fix but optimization.
2591 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Added new config entry [Identity] to fork the server and run
2594 it as specific user and group. A patch from Bostik.
2596 * Imported Dotconf configuration library into lib/dotconf.
2597 This will be used to create the SILC configuration files later.
2598 It will appear in the distsribution after this commit.
2600 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * A big code auditing weekend happening. Auditing code for
2603 obvious mistakes, bugs and errors. Also, removing any code
2606 Removed files for being obsolete:
2608 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2609 inline in the file lib/silcutil/silcbuffer.h)
2611 o lib/silcutil/silcbufutil.c (the header has inline versions)
2613 Changed code to fix possible error conditions:
2615 o The buffer formatting routines now check that the destination
2616 buffer really has enough space to add the data. This applies for
2617 both buffer formatting and unformatting
2618 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2619 unformatting was changed to accomodate following rules:
2620 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2621 sent to the function while XXX_*STRING will not allocate or copy
2622 the data into the buffer. Instead it sets the pointer from the
2623 buffer into the pointer sent as argument (XXX_*STRING used to
2624 require that the pointer must be allocated already). This change
2625 makes this whole thing a bit more consistent and more optimized
2626 (note that the data returned in the unformatting with XXX_*STRING
2627 must not be freed now). The routines return now -1 on error.
2629 o Tried to find all code that use buffer_format and buffer_unformat
2630 and added return value checking to prevent formatting and
2631 especially unformatting errors and possible subsequent fatal
2634 o Changed ske->x and ske->KEY to mallocated pointers in
2635 lib/silcske/silcske.h. Fixed possible data and memory leak.
2637 o Added return value checking to all *_parse* functions. Fixed
2638 many memory leaks as well.
2640 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2641 so that buffer overflows would not happen. All code now also
2642 checks the return value as it can fail.
2644 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2646 * Added reconnection support to server if the normal server looses
2647 its connection to the router (for example if router is rebooted).
2648 The server performs normal reconnection strategy implemented
2649 to the server. Affected file silcd/server.c.
2651 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2653 * Added new packet type SILC_PACKET_SET_MODE that is used to
2654 distribute the information about changed modes (for clients,
2655 channels and clients channel modes) to all routers in the
2656 network. Updated the protocol specification accordingly.
2658 Added functions into silcd/packet_send.c and
2659 silcd/packet_receive.c: silc_server_send_set_mode,
2660 silc_server_set_mode.
2662 Added new files silcmode.[ch] into lib/silccore that implements
2663 the encoding and decoding of Set Mode Payload. Added new type
2664 SilcSetModePayload. Moved the definitions of different modes
2665 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2667 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Oops, a little mistake in server's connection authentication
2670 protocol. The protocol is not ended with FAILURE but with
2671 SUCCESS if the authentication is Ok. :) Affected file is
2674 * Implemented NICK_CHANGE notify handling in server in the file
2675 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2676 the local clients on the channel. After the changing nickname
2677 in router environment snhould work and the [<unknown>] nickname
2678 should appear no more.
2680 The silc_server_replace_id function that receives the Replace ID
2681 payload now sends the NICK_CHANGE notify type also in the file
2682 silcd/packet_receive.c
2684 * Changed WHOIS and IDENTIFY command to support the maximum amount
2685 of arguments defined in protocol specs (3328 arguments). This
2686 fixed a bug that caused problems when there were more than three
2689 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2691 * Added extra parameter, command identifier, to the
2692 silc_client_send_command so that explicit command identifier
2695 Changed that ID list routines uses specific command identifier
2696 when sending WHOIS/IDENTIFY requests to the server so that they
2697 can be identified when the reply comes back.
2699 Affected files lib/silcclient/command.[ch],
2700 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2702 * Added `sender' argument to silc_server_packet_send_to_channel
2703 to indicaet the sender who originally sent the packet to us
2704 that we are now re-sending. Ignored if NULL. Affected file
2705 silcd/packet_send.[ch].
2707 * Added some server statistics support in silcd/server_internal.h
2708 SilcServerStatistics structure and around the server code. Also
2709 send some nice statistics information when client is connecting
2712 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2714 * Fixed channel ID decoding in server's JOIN command reply in
2715 silcd/command_reply.c
2717 * Fixed braodcasting of replace ID payload to not to send it if
2718 we are standalone server in silcd/packet_receive.c.
2720 * Fixed all channel message sending routines to not to send
2721 packets to clients that has router set, since they are routed
2722 separately in the same function earlier. Affects file
2723 silcd/packet_send.c and all channel packet sending functions.
2725 * In USERS reply, res_argv[i] are not allocated, the table
2726 is allocated. Thus changed that free the table, not its
2729 * In server's whois_check and identify_check if the client is
2730 locally connected do not send any WHOIS commands - they are not
2733 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2735 * Fixed some minor bugs in client when sending WHOIS command. The
2736 arguments was in wrong order.
2738 * Removed statis function add_to_channel from server in
2739 silcd/command.c that was previously used with the joining but
2742 * Tested USERS command in router environment successfully with two
2743 routers, two servers and two clients.
2745 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * Reorganized the USERS command and command reply in client library
2748 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2749 When the command is given by user we register a pending command
2750 callback that will reprocess the command after the reply has been
2751 received from the server. When reprocessing the packet we then
2752 display the information. Thus, the USERS information is displayed
2753 now in the command callback instead of in the command reply
2754 callback. The processing of the command is same as previously
2755 when server has sent the command reply in the JOINing process.
2757 * Added to USERS command in silcd/command_reply.c to join the client,
2758 we didn't use to know about, to the channel after we've created
2759 a client entry for it. Also, for clienet we did know already still
2760 check whether it is on the channel or not and add it if not.
2762 * Removed silc_server_command_join_notify as the function and its
2765 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2767 * Changed the client's pending command handling to the same as the
2768 server's pending command handling. It is also now possible to
2769 execute command reply functions from other command reply
2770 function as the function callbacks for commands and command
2771 replies are one and same. The pending commands are not static
2772 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2773 in client connection context. Thus, pending commands are server
2774 connection specific as it is convenient.
2776 Changed the function silc_client_command_pending and
2777 silc_client_command_pending_del and added new function
2778 silc_client_command_pending_check. Removed the
2779 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2782 * Added cmd_ident, current command identifier, to the client
2783 connection context in lib/silcclient/client.h to keep track on
2784 command identifiers used in command sending. Client's command reply
2785 function handling now supports the mandatory command identifiers.
2787 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2788 funtions in client to fully support pending command callbacks.
2790 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2791 as one of the arguments to the application in the command reply
2794 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2795 before first releasing SILC but came back. Now it is removed again
2796 and should come back nomore. The FORWARDED flag was used only
2797 by the JOINing procedure by forwarding the command packet to router.
2798 Now, the JOINing procedure has been changed to more generic (due
2799 to various router environment issues) and FORWARDED is not needed
2800 anymore for anything. The protocol specification is yet to be
2803 Now, removed silc_server_packet_forward from server and the flag
2804 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2806 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2808 * Renamed NAMES command to USERS command. The NAMES was named that
2809 due to historical reasons. Now it is renamed. Also, rewrote
2810 parts of the USERS command. The nickname list is not sent anymore
2811 by the server. Only Client ID and mode lists are sent in the USERS
2812 command. Changed this also to the protocol specification.
2814 The client now resolves the names and stuff after it receives
2815 the USERS list from the server when joining to the channel.
2817 * WHOIS and IDENTIFY commands has been changed to support multiple
2818 Client ID's per command. One can now search for multiple users
2819 in the network by sending only one WHOIS or IDENTIFY command.
2820 Changed the code and the protocol specifications.
2822 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2823 uses silc_server_command_whois_parse to parse the request. */
2825 * If normal server, do not parse the WHOIS and IDENTIFY requests
2826 before sending it to the router. Saves some time.
2828 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2830 * Fixed JOIN command on client library. Wrong number of arguments
2831 used to crash the client.
2833 * Added silc_server_channel_has_global function to check whether
2834 channel has global users or not.
2836 * Added silc_server_channel_has_local function to check whether channel
2837 has locally connected clients on the channel.
2839 * The silc_server_remove_from_one_channel now checks whether the
2840 channel has global users or not after given client was removed from
2841 the channel. It also checks whether the channel has local clients
2842 on the channel anymore. If it does not have then the channel entry
2843 is removed as it is not needed anymore.
2845 * The silc_server_notify now checks on JOIN notify whether the joining
2846 client is one of locally connected or global. If it is global then
2847 the channel has now global users on the channel and that is marked
2848 to the channel entry. Also, it now saves the global client to
2849 global list who is joining and JOINs it to the channel. This is
2850 for normal server, that is.
2852 Changed silc_server_send_notify_on_channel,
2853 silc_server_packet_relay_to_channel and
2854 silc_server_packet_send_to_channel check if we are normal server
2855 and client has router set (ie. global client) do not send the
2856 message to that client, as it is already routed to our router.
2858 * Implemented LEAVE notify type handling in silc_server_notify
2861 * Tested LEAVE command in router environment successfully. Tested
2862 with two routers, two servers and two clients.
2866 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2868 * Implemented SIGNOFF notify type handling in silc_server_notify
2871 * silc_server_remove_id now removes the client entry from all channels
2872 it has joined and thusly sends SIGNOFF notify type.
2874 * Rewrote the NAMES list generation in server by removing two excess
2875 loops. The lists are created now inside one loop.
2877 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * silc_server_remove_channel_user checks now also global list
2880 for channel and client.
2882 * silc_server_new_channel_user checks now both local and global
2883 list for channel and client. Fixed a bug in client id decoding.
2884 Used to decode wrong buffer.
2886 * silc_server_channel_message checks now both local and global
2887 list for channel entry.
2889 * Tested channel joining (hence JOIN) in router environment
2890 successfully. Tested with two routers, two servers and two
2893 * Tested channel message sending in router environment successfully.
2895 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2897 * Added silc_server_save_channel_key into server.[ch] to save the
2898 received channel key in Channel Key payload processing. It is
2899 also used in JOIN command reply handling.
2901 Equivalent function silc_client_save_channel_key added into
2902 client.[ch] into client library.
2904 * Changed JOIN command reply to send information whether the channel
2905 was created or not (is existing already) and the channel key
2906 payload. Changed protocol specs accordingly.
2908 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2909 the request was sent by ID and not by nickname. Crashed on
2912 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2915 now correctly save the received data.
2917 * silc_server_free_sock_user_data now notifies routers in the
2918 network about entities leaving the network.
2920 At the same time implemented functions silc_server_remove_id
2921 and silc_server_send_remove_id to receive and send REMOVE_ID
2922 packets. The packet is used to notify routers in the network
2923 about leaving entities. The ID removed will become invalid in
2926 * Added function silc_idlist_del_server into server. Removes and
2927 free's server entry from ID list.
2929 * silc_server_private_message function now checks, if we are router,
2930 that the destination ID really is valid ID, naturally.
2932 * In router when NEW_ID packet is received (for new client) the
2933 hash of the Client ID is saved in the ID Cache but the
2934 client->nickname is set to NULL, instead of putting the hash
2937 IDENTIFY command now also checks that client->nickname must be
2938 valid. If it is not if will request the data from the server who
2939 owns the client. Added new function
2940 silc_server_command_identify_check.
2942 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2943 to set the command to already allocated Command Payload.
2945 * Tested private message sending in router environment with two
2946 routers, two servers and two clients. Fixed minor bugs and now
2949 * Fixed segfault from client's NAMES command. Used to crash if
2952 * Forwarded packets must not be routed even if it is not destined
2953 to the receiver. Changed server code comply with this.
2955 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Added `require_reverse_mapping' boolean value to ServerParams
2958 structure. If TRUE (not default) the server will require that
2959 the connecting host has fully qualified domain name.
2961 If the reverse mapping is not required and hostname could not be
2962 found the IP address is used as hostname.
2964 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2966 * Implemented version string checking to both client and server.
2967 The check is incomplete currently due to the abnormal version
2968 strings used in development version of SILC.
2970 * Changed all command functions in server to use the new
2973 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Changed char *data to unsigned char *data in ID Cache system to
2976 support binary data as ID Cache data. Changed code to support
2977 binary data in lib/silccore/idcache.c.
2979 * Renamed silc_server_packet_relay_command_reply to
2980 silc_server_command_reply as it is normal packet receiving
2981 function. Rewrote the function to accept command replys for
2982 servers and not only for clients.
2984 * Mark remote router always as registered server if we are connecting
2985 to it. Otherwise, commands sent by the router to us are ignored.
2987 * All ID List find routines now returns the ID Cache Entry pointer
2988 as well if requested.
2990 * WHOIS command works now in router environment, tested with two
2991 routers, two servers and two clients.
2993 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2994 in router environment (as it is almost equivalent to WHOIS) but
2995 hasn't been tested thoroughly. Added new functions:
2997 silc_server_command_identify_parse
2998 silc_server_command_identify_send_reply
2999 silc_server_command_identify_from_client
3000 silc_server_command_identify_from_server
3002 * Disabled route cache adding because adding two different ID's with
3003 same IP replaces the old cache entry thus giving wrong route.
3004 The entry->router->connection is always the fastest route anyway
3005 so route cache may not be needed. Of course, new routes maybe
3006 established after receiving the ID when the entry->router->connection
3007 might not be anymore the most optimal.
3009 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Add route cache for received ID for fast routing.
3013 * Added silc_server_packet_route to route received packet on router
3014 that is not destined to us.
3016 * Renamed silc_server_get_route to silc_server_route_get.
3018 * Added id_string and id_string_len fields into SilcServer to
3019 include encoded ServerID for fast comparing without excess
3020 encoding of the ID's.
3022 * Cleaned up WHOIS command on server side. Added following static
3025 silc_server_command_whois_parse
3026 silc_server_command_whois_check
3027 silc_server_command_whois_send_reply
3028 silc_server_command_whois_from_client
3029 silc_server_command_whois_from_server
3031 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3032 arguments in command replies. All command functions should be
3033 updated to use this macro.
3035 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3037 * Minor typo fixes on command reply handling on server.
3039 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Added silc_server_command_add_to_channel internal routine to add
3042 the client to the channel after router has created the channel and
3043 sent command reply to the server.
3045 * Added generic silc_server_send_command to send any command from
3048 * Use static buffer with ID rendering instead of duplicating data.
3050 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3052 * Fixed a channel user mode bug when joining to a channel server gave
3053 everybody channel founder rights, oops.
3055 * We mark ourselves as the router of the incoming server connection
3056 if we are router ourselves. This way we can check in some packet
3057 sending functions whether it is locally connected server. For
3058 incoming router connections we put NULL.
3060 * For router sending packets locally means now always sending the
3061 packet cell wide; to local clients and local servers. For normal
3062 server sending packet locally means sending it to only local
3065 * Fixed the JOIN command to really work in router environment. If the
3066 channel is created it is always created by the router. Router is
3067 also responsible of making the initial joining to the channel,
3068 sending JOIN notify to the sending server and distributing
3069 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3070 does not exist server doesn't do anything else but forward the
3071 command to the router which performs everything.
3073 * Added silc_server_send_channel_key function to send the Channel Key
3076 * Added silc_server_create_channel_key to create new channel key. The
3077 channel key is now re-generated everytime someone joins or leaves
3078 a channel, as protocol dictates. Note: channel->key_len is the
3081 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3084 packet_receive.[ch] to separate packet sending and receiving
3085 routines. The server.[ch] now includes everything else including
3086 actual packet processing (writing and reading data) and other
3089 Renamed silc_server_private_message_send_internal to
3090 silc_server_send_private_message. The routine is still though
3091 used only to relay private messages as server does not send
3092 private messages itself.
3094 Renamed silc_server_new_channel to silc_server_create_new_channel
3095 and added new function sicl_server_new_channel that handles the
3096 incoming New Channel packet. Added also new sending function
3097 silc_server_send_new_channel to send New Channel Payload.
3099 * Added new function silc_server_notify to process incoming notify
3100 packet to the server/router. Server may then relay the notify
3101 to clients if needed.
3103 * Added new function silc_server_new_channel_user to process incoming
3104 New Channel User packet. Router will redistribute the packet and
3105 send JOIN notify to its local clients and locally connected servers
3106 if needed. Normal server will send JOIN notify to its local client
3107 on same channel when received this packet. Added also corresponding
3108 sending function silc_server_send_new_channel_user to sent the
3111 * Added boolean route argument to send_notif_to_channel and
3112 packet_send_to_channel functions to attempt to route the packet
3113 if it is TRUE and send only locally if it is FALSE.
3115 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * silc_server_replace_id now broadcasts the received replace ID
3118 packet if it is not broadcast packet already. The router must
3119 broadcast to inform other routers about changed ID.
3121 * Added backpointer to server's router into SilcServer context in
3122 silcd/server_internal.h.
3124 * Fixed silc_server_packet_broadcast to send correct broadcast
3127 * The channel key is now distributed to the local client as soon
3128 as it is received from the router (in router environment) so that
3129 no other packet may be sent for the channel until client has
3132 * silc_server_remove_channel_user now broadcasts the received
3133 Remove Channel User packet if it is not broadcast packet already.
3134 The router must broadcast to inform other routers about removed
3137 * Added users field into SilcPacketContext that is a reference count
3138 of the context. One can increase the reference count by calling
3139 silc_packet_context_dup which is now changed to just increase the
3140 reference count instead of duplicating the data. The reference
3141 count is decresed by calling silc_packet_context_free that will
3142 free the data after the reference count hits zero.
3144 For now on the packet context and everything allocated into it
3145 (including the raw packet from network) must be freed by calling
3146 the new silc_packet_context_free function. Added also new function
3147 silc_packet_context_alloc that must be used now to allocate the
3148 context. This also means that if a routine is asynchronous from
3149 silc_[client/server]_packet_parse_type the packet context must
3150 be duplicated by calling silc_packet_context_dup. Otherwise it
3151 gets free'd after silc_[client/server]_packet_parse_type returns.
3152 Also, one must remember that if packet is duplicated then its
3153 reference count must be decresed by calling the free function as
3154 many times as it was duplicated.
3156 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3157 from both client and server.
3159 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Made joining to a channel working in router environment.
3163 * Cleaned up JOIN command on server side and create function
3164 silc_server_command_join_channel internal routine to make the
3167 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Changed silc_command_pending list to SilcDList. Also, added
3170 `ident' field to SilcServerCommandPending structure to identify
3171 the reply and to call correct callback.
3173 Added silc_server_command_pending_check function to replace the
3174 corresnponding macro. The silc_command_pending list is not
3177 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3178 to set identifier to previously allocated Command Payload. It
3179 is used to set identifier for command when resending Command
3182 * Added silc_command_payload_encode_payload to encode Command
3183 Payload buffer from SilcCommandPayload structure.
3185 * Added silc_argument_payload_encode_payload to encode Argument
3186 payload buffer from SilcArgumentPayload structure.
3188 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * Changed WHOIS command to support router connection on server side.
3191 The whois request is always sent to router unless the server is
3192 standalone server. After server has received the reply from the
3193 router will it send the reply to the client.
3195 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3196 broadcast received broadcast packet. The function is used only
3197 by router. The broadcast packet is always sent to the router's
3200 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3201 render given ID to printable string, for log files for example.
3203 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3205 * Made basic router to router connections working. At least they
3206 can now connect to each other but nothing really works the way
3207 they are supposed - yet.
3209 * Added new initiator token to RouterConnection configuration
3210 file in silcd/serverconfig.[ch]. It is used to tell whether we
3211 are the initiator to the remote router or whether we'll expect
3212 the other end to connect.
3214 * Moved registering of listener task to silc_server_init, hence
3215 the server starts listenning as soon as it is run, even if it
3216 does not have connections to other routers. Let's see how well
3219 * Changed default connection retry timeouts for more suitable in
3222 * Removed cipher and such arguments from silc_idlist_add_client
3223 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3224 Added new function silc_idlist_add_data to add the keys and stuff
3227 * Added SilcIDListData structure and added it to SilcClientEntry
3228 and SilcServerEntry as their first field in the structure. This
3229 way we can explicitly cast the ID entries to the SilcIDListData
3230 structure and get common data for the entries. In past, we had
3231 to first check what type of connection it is and then cast it to
3232 correct ID entry type. Now, we can directly cast the opaque
3233 pointer to the SilcIDListData (no matter what ID entry it actually
3234 is) and get the data needed.
3236 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3238 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3239 in some circumstances even if threre were timeout tasks, though not
3240 IO tasks, but tasks anyway. Now fixed.
3242 * Defined SilcServerConnection structure to hold connection specific
3243 stuff about directly connected servers and routers. The definition
3244 is currently in silcd/server_internal.h. I thought about having
3245 a bit more important role fro this struct but for now it is used
3246 only when connecting to other server (or router actually).
3248 * Added connecting retry support in server when connecting to
3249 router(s). The retry feature implement exponential backoff
3250 algorithm. Also, added SilcServerParams structure to hold default
3251 parameters for server. For now, it include these retry settings
3252 and are hard coded. After server is moded to be as Silc Server
3253 Library this structure will be more important.
3255 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3257 * Changed client librarys channel->clients table to SilcList and
3258 changed code accordingly.
3260 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Changed client's channel table to SilcList and changed code
3263 accordingly. Also changed SilcChannelClientEntry to include back-
3264 pointer to the channel so that client entry can use that structure
3265 as list as well and we have fast cross-reference to the channel.
3266 This change dramatically decreased the complexity of channel
3267 handling with client entry and vice versa (removed one extra
3268 loop when searching for channel entry from many functions).
3270 * Changed server->sim from table to SilcDList and changed code
3273 * NAMES command can now be used from user interface. It will show
3274 the user list on the channel, neatly.
3276 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3277 Code now saves realname of the user if it becomes available.
3279 * Renamed configure.in to configure.in.pre and made ./prepare
3280 script to automatically add correct version string to
3281 configure.in which it creates from configure.in.pre.
3283 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * NAMES command reply now shows users mode with the nickname when
3288 * Moved silc_client_ch[u]mode[_char] functions from
3289 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3290 place sucks, they are utility functions and should be in some
3293 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3295 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3298 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Added TRQ (efficient deque and list library) into lib/trq. This is
3303 a very good list library that is currently used in the SILC. Defined
3304 SilcList API over the library because I didn't like the API very
3305 much. See lib/trq/silclist.h for the API and examples of how to
3306 use the API. Fixed various places in the code to use the new
3307 SilcList API. The SilcList is meant for lists that has a structure
3308 already defined as a list. It is not suitable to add just some
3309 context to the list (in TRQ, the context is the list actually).
3311 So, I defined SilcDList that can be used for the purpose where
3312 predefined list structure does not exit. This can be used as
3313 such list. Now some context just can be added to the SilcDList.
3314 Currently this list is not used in the SILC just yet, though there
3315 are a lot places where this can replace dynamically allocated
3316 tables and I will fix these places, later, to use SilcDList.
3317 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3318 and use TRQ internally).
3320 Also fixed some annoying warning messages that the original TRQ
3321 code generated. Also minor changes to TRQ's Makefile.in.
3323 * Added support for querying by Client ID to both WHOIS and
3324 IDENTIFY commands into server, as required by the protocol.
3326 * Removed method function pointers from SilcBuffer structure. They
3327 weren't used to anything and just increased the context size for
3328 no good reason. This change also made silc_buffer_alloc and
3329 silc_buffer_free functions inline functions.
3331 * Disabled command flooding detection support until it's fixed so
3332 that it accepts commands in but does not execute them more than once
3335 * Added silc_net_localhost(), to return local hostname, into
3336 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3337 that must be initialized before calling silc_client_init.
3339 * Added new function: silc_server_send_notify_on_channels to send
3340 notify messages to all channels client has joined. It is assured
3341 that the message is sent only once per client.
3343 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3344 lib/silcutil/silcutil.[ch] as silc_format function. The new
3345 function is generic and is used by server as well, not only by
3346 the logging routines.
3348 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3349 the provided version string was not acceptable. Added new function:
3350 silc_ske_check_version into lib/silcske/silcske.h. The function
3351 must be implemented by the application (client or server) and it
3352 does not reside in the SKE library. The function checks the version
3353 string remote end sent.
3355 * Added back pointers (to opaque context and to SilcSocketConnection)
3356 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3358 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3359 duplicate packet context structure.
3361 * Changed `notify' client operation to send same arguments as client
3362 receives from server except for ID's. ID's are mapped to correct
3363 ID entry and that is returned. Also, if channel entry is not sent
3364 by server but the notify is for channel the channel entry is sent
3365 to application (otherwise application doesn't know that it is for
3366 channel (library gets it from packet's Destination ID)).
3368 * Added silc_client_remove_from_channels into client library to
3369 remove a client from all channels it has joined to. Used when
3370 received SIGNOFF notify from server. Added also new function
3371 silc_client_replace_from_channels to replace old ID entry with
3372 new ID entry on all channels. Used when received NICK_CHANGE
3375 * Fixed ID Cache list handling in silc_idlist_get_client in
3376 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3377 to get (or query) client by ID.
3379 * Updated TODO list.
3381 * Added connection authentication status message defined by the
3382 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3383 support for these into the code in client and server side.
3385 * Added generic function silc_client_send_command to send any command
3386 with variable argument list. Application should use this function
3387 to send commands if the command functions provided by the library
3388 does not suite for the application's user interface needs.
3390 * Added new `failure' client operation. Application is notified about
3391 received failure packet if client is executing a protocol. In this
3392 case the protocol's execution has failed.
3394 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3395 is required by the protocol.
3397 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3398 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3401 * Added status flag to SilcSKE object to indicate realtime status
3402 of the SKE protocol.
3404 * Application receives now exactly same command reply arguments as
3405 the library receives from server. However, if ID is received the
3406 corresponding ID entry is returned to the application (eg. Client
3407 ID is mapped to correct SilcClientEntry entry and that is returned).
3408 Changed command_reply client operation due to this change.
3410 * Changed all ID's in commands and in command replys as ID Payloads.
3411 Change affected both client and server side codes.
3413 All ID's sent in SILC network (with execption of ID's in SILC
3414 Packet header) are sent in ID Payload to support variable length
3417 * Server now notifies nick changes and notifies all clients on
3418 the channels about the new nickname (about the new Client ID,
3421 * Implemented CMODE command to change channel modes. Supports all
3422 channel modes defined by the protocol specs except ban and invite
3423 lists. (Also, private channel key mode is supported but support for
3424 setting private channel key in client is missing, thus, this mode
3425 has no effect on client side (except that server requires that the
3426 client uses private channel key and normal channel traffic does not
3429 Also, invite mode works per se, but INVITE command does not work
3430 yet correctly, so you can set channel as invite only channel but
3431 inviting clients to the channel does not work (it is yet to be
3432 thought what's the best way to do it).
3434 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3435 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3436 Implemented CUMODE command to change user's mode on the channel.
3437 Supports all modes defined by the protocol specs.
3439 * Added NAMES command reply to return users modes on the channel.
3441 * Removed unnecessary and slow ciphers from lib/silccrypt.
3443 * Set SO_KEEPALIVE option to connection sockets by default.
3445 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3447 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3448 redefined the Notify Payload into protocol specs.
3450 * Added silc_id_payload_parse_id to get ID directly from raw
3453 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3455 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3456 accept searching by Client ID as well.
3458 * Added support for LEAVE and SIGNOFF notify types in client library.
3460 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3461 to parse ID Payload from raw data.
3463 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3465 * Added flags parameter into silc_ske_assemble_security_properties
3466 function in lib/silcske/silcske.[ch].
3468 * Changed notify client operation to fit better for notify messages
3469 sent by server. The notify payload received from server is now
3470 passed to the application (after parsing it to SilcNotifyPayload).
3471 It is application's responsibility to retrieve the arguments
3472 from the payload and show the message the way it wants. The message
3473 sent by server is implementation specific.
3475 * Changed public keys to comply with the protocol specification.
3476 Old public keys are not supported anymore and are not compatible.
3478 * Removed nickname from Channel Payload as the latest draft removed
3479 it. The client must resolve the nickname from the NAMES command
3480 reply received when it joined the channel.
3482 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3484 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Fixed some errors in protocol specification drafts.
3488 * Created lib/silccore/silcnotify.c to implement Notify Payload
3489 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3490 generic payloads described by protocol specifications. The file
3491 includes implementations for ID Payload and Argument Payload.
3493 * Changed Command Payload implementation to use the new Argument
3494 Payload. Changed command_xxxx_payload to command_payload_xxxx
3495 to comply with SILC coding conventions.
3497 * Added suppport for Argument Payload handling in Notify Payload
3498 implementation as protocol requires it. Added the new support
3499 into server and client lib as well.
3501 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Added support for multiple nicknames on same channel. [n] is
3504 added locally to the nickname if there are more than one same
3505 nicknames on the channel.
3507 * Server now sends all nicknames that matched WHOIS request.
3508 Client also shows the list received from server.
3510 * Added TOPIC command to client side. User can now set and show
3511 current topic on channel.
3513 * Added MOTD command to client and server. Also, server sends the
3514 motd when client connects to the server.
3516 * Changed version strings to comply ISO 8601.
3518 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3520 * Fixed protocol error handling in client library. It should now
3521 cope even if the SKE fails for some reason.
3523 * Made new protocol specification drafts for submitting to IETF.
3525 * Implemented TOPIC command to server in silcd/command.c.
3527 * Added two new notify types into lib/silccore/silcnotify.h:
3528 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3529 notify nickname change and topic setting/change on a channel.
3531 * API change of command_reply operation in client library. The
3532 application gets now the status type received from server as well.
3534 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3538 * Cras fixed and optimized the packet handling even further and
3539 it should work now. Minor change to the prototype of function
3540 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3542 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3544 * Added new function into lib/silcutil/silcschedule.[ch]:
3545 silc_schedule_with_fd to select() a specified fd. The function
3546 returns after timeout expires or data arrives or goes. The
3547 function is used by packet routines to wait that all data is
3548 received from network.
3550 * Fixed data reading from network in lib/silccore/silcpacket.c.
3551 The code now assures that all data is read from the fd and then
3552 continues packet processing. This was a bug fix since the code
3553 used to drop some data in some circumstances.
3555 * Added new function into lib/silcclient/client.[ch]:
3556 silc_client_start_key_exchange to start key exchange after
3557 connection has been established to server. The code internally
3558 now uses this funtion but its main purpose was to provide it
3559 for applications that perform their own connecting. After
3560 application has created a connection it merely calls this
3561 function to start the key exchange between client and server.
3562 The library takes care of everything else after that.
3564 Updated also lib/silcclient/README to explain the usage of
3567 * Do not send to application information that connection has
3568 been established. Application gets notified it by connect
3571 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3573 * Applied cras's patch to add silc_schedule_one function. The
3574 function runs scheduler once and returns.
3576 * Fixed the scheduler after cras messed it up. The timeout
3577 handling works now as it's supposed to work.
3579 * Added into lib/silccore/ silcnotify.h to include notify
3580 message types support. Changed silc_server_send_notify*
3581 functions, in server.[ch], to support those new notify types.
3582 Added the support for the notify types into client library,
3583 as well. Added new notify client operation into ops.h in
3586 * Changed silc_server_packet_send_to_channel to send normal
3587 packets instead of just channel message packets. The function
3588 is now used to send the notify packets to channels. It is not
3589 used to send channel message packets anymore, as server never
3592 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3593 va_arg()s as it seems to require it nowadays. I guess, if SILC
3594 is compiled with older va_arg() the new code should work anyway.
3596 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Splitted core library. Core library (lib/silccore) includes
3599 now only SILC protocol specific core (and common) components.
3600 Created new utility library (lib/silcutil) that includes more
3601 generic purpose stuff. The stuff for util library was taken
3602 from the old core library. This was minor and easy split.
3604 * Created SILC Client Library (lib/silcclient) that includes
3605 implementation of the SILC client without user interface. This
3606 was major move from silc/ directory. The code has been changed
3607 so that it is transparent towards the user interface. The
3608 silc/ directory includes now the same user interface as before
3609 and it uses the new client library. Read lib/silcclient/README.
3610 Basicly, the client library performs everything else related
3611 to SILC except user interface handling. Also, configuration
3612 files are considered to be part of user interface and library
3613 does not handle them.
3615 This change also changed a lot of structures, function naming etc.
3616 Most important change was that SilcClientWindow object was
3617 renamed to SilcClientConnection in the client library. Created
3618 also new file lib/silcclient/ops.h. Also added new files
3619 silc/local_command.[ch] and silc/client_ops.[ch].
3621 All these changes were made to make it easier for user interface
3622 designers to create what ever user interface for the SILC client
3625 It is also expected that the server will be moved to lib
3626 directory as well and SILC Server Library will be created;
3627 sometimes in the future.
3629 * Removed Local commands from lib/silccore/silccommand.h as
3630 they are application specific and new client library does not
3631 handle any of those anymore.
3633 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3634 old client implementation in silc/.
3636 * Added support for callback functions in SILC_LOG_* macros.
3637 Application can now set its own callbacks that will be called
3638 instead of using the default functions that will always print
3639 the debug messages to stderr (or stdout). Also, debugging can
3640 now be disabled by setting silc_debug to FALSE and re-enabled by
3641 setting it to TRUE. Note, that logging will still work even
3642 if debugging is disabled.
3644 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3645 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3646 silc_log_reset_debug_callbacks.
3648 * To enable debugging in silc client one must give now -d
3649 option on command line.
3651 * Changed silc_schedule_init to automatically allocate task queues
3652 if they are not allocated before calling it.
3654 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3656 * Added GMP 3.1 into math library.
3658 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3660 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3661 a channel in SILC network. The packet is used by servers and
3662 routers to notify other routers that user has left a channel.
3663 This little feature was missing until now. Added the feature
3664 to protocol specification as well.
3666 Added functions: silc_server_send_remove_channel_user and
3667 silc_server_remove_channel_user into server.[ch].
3669 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3670 lib/silccore/silcpacket.h. However, they are not implemented
3673 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Fixed joining to a channel and sending channel messages
3676 between server and router. The channel message sending should
3677 now work inside a cell.
3679 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Fixed the private message sending between server and router.
3682 The private message sending should now work inside a cell.
3684 * Added silc_server_replace_id into server.[ch] to replace
3685 existing ID in the SILC network.
3687 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3688 and silc_idlist_replace_server_id into idlist.[ch] in server.
3690 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3692 * Fixed the server to server connections. Server can again now
3693 connect to router. Router to router connections probably does
3696 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3698 * Added dynamic protocol registering support. Now protocols can
3699 registered and unregistered on the fly. Patch by cras.
3701 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3703 * Added lib/contrib directory to hold routines that some platforms
3704 don't have but are needed by SILC.
3706 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3707 into lin/contrib to provide getopt() and getopt_long() for
3708 those who don't have it.
3710 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3712 * Added AWAY command to client. When away message is set and
3713 client receives a private message packet the client automatically
3714 replies to the sender with the away message.
3716 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3717 bug seemed to be the cause of recent problems when compiling
3720 * Added version detection support to SKE protocol specification
3721 and added the new changes to the SKE implementation as well.
3722 There were other minor changes in the SKE protocol as well.
3724 Many changes in lib/silcske/silcske.[ch] and in
3725 lib/silcske/payload.[ch].
3727 * Added ^U functionality, clear input line. Patch from cras.
3729 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Mainly small bugfixes on core library. Fixed some debugging
3732 logging and buffer overflow in silclog.c.
3734 * Updated config.sub and config.guess on the distribution tree.
3736 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Added command lagging support in server. Client may execute
3739 commands now only once in two seconds.
3741 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3743 * Optimized packet reception. MAC computation and checking is now
3744 also more optimized. A lot previously duplicated code is now
3745 used as generic by both client and server.
3747 * Fixed key pair generation in clientutil.c
3749 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3751 * Added into lib/silccore/silcbufutil.[ch] new function;
3752 silc_buffer_realloc.
3754 * Moved generic packet sending/encryption functions to
3755 lib/silccore/silcpacket.[ch] from client and server. Some
3756 rewriting of the functions.
3758 * Moved all generic packet reception/decryption functions to
3759 lib/silccore/silcpacket.[ch] from client and server. The
3760 packet processing is now much cleaner in both client and server.
3761 These were major changes in both client and server.
3763 * Created many common functions in server to do packet sending.
3764 Previously code were duplicated a lot, this has been removed
3767 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Rewrote major parts of the ID cache system. Don't know
3770 whether it is better now or not but at least the API is more
3773 * Major rewrite on ID cache stuff on client because of the ID
3774 cache API changes. Added idlist.c to client.
3776 * Also major rewrite on ID cache stuff on server as well.
3777 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3778 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3779 in hand, instead they are all put into the ID cache system now.
3780 All server_idlist_* routines uses ID cache now instead of
3781 traversing its own lists (those lists does not exist anymore).
3782 SilcIDList though still exists. Also, SilcXXXEntry's are
3785 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Finally made the SKE implementation compliant to the protocol
3788 specification. All mp integers are now binary encoded as
3789 opposed being HEX encoded.
3791 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3794 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3795 functions: silc_[encode/decode]_pem. Also added function
3796 silc_encode_pem_file to PEM encode with newlines ('\n') for
3799 * SILC public keys are now encoded either PEM or binary. Same
3800 option is for private keys as well. By default private keys
3801 are binary encoded and public keys PEM encoded. Silly HEX
3802 encoding were removed.
3804 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3805 function to create fingerprints.
3807 * Fixed a bug in SHA1; does not change the original data anymore.
3809 * Partly implemented INFO command on client and server side.
3810 Fixed CLEAR command. Changes to SERVER command; show current
3811 server(s) when giving command without arguments. Added
3812 VERSION command to client.
3814 * Added check to server that unregistered connections cannot
3815 execute commands (unless it is specificly allowed).
3817 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3819 * Fixed screen refresh.
3821 * Fixed channel joining bug from client. On some circumstances
3822 client tried to join to a channel it had already joined.
3824 * Added public key verification process into client's protocol.c.
3825 The client now verifies the public key from user and saves
3826 it into ~./silc/serverkeys/ directory.
3828 Added into: clientutil.[ch]: silc_client_verify_server_key.
3830 * Changed SKE protocol's silc_ske_initiator_finish function
3831 to accept callback function that verifies the received public
3832 key. Removed old silc_ske_verify_public_key function.
3834 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3837 silc_pkcs_private_key[_data]_set.
3839 * Made the password and public authentication more cleaner in
3840 server's protocol.c.
3842 * Removed historic and obsolete protocol `channel_auth' from
3843 both client and server.
3845 * Removed wrong way of sending command status messages from
3846 server to client in server's command.c. The old way violated
3847 protocol specification.
3849 Changes to silccore/silccommand.[ch]: removed
3850 silc_command_encode_status_payload -> not needed anymore,
3851 changed silc_command_encode_payload_va to accept extra
3852 argument on variable argument list. The argument type must
3853 now be provided to the function. Also, added new function:
3854 silc_command_encode_reply_payload_va which is same as
3855 normal command_encode_payload_va except command status type
3856 is provided as extra argument.
3858 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Added ~./silc directory handling. The directory includes the
3861 public and private keys for the client.
3863 Added silc_client_check_silc_dir, silc_client_create_identifier
3864 and silc_client_load_keys.
3866 * Implemented SILC protocol compliant public key. Added public
