1 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Merged a splitted window bug from Irssi CVS tree. The affected
4 file is irssi/src/fe-text/textbuffer-view.c.
6 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
9 irssi/src/fe-text/gui-window.c.
11 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
12 to in-active server. The affected file is
13 irssi/src/silc/core/client_ops.c.
15 * Resolve the client in USERS command reply if the entry does
16 not have username resolved. The affected file is
17 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
18 command to WHOIS command to really resolve stuff. The USERS
19 is not used any more in any critical section so WHOIS can
20 be used even though it might be slower than IDENTIFY.
22 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
25 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
27 * Changed the protocol API a bit more consistent in the
28 lib/silccore/silcprotocol.[ch].
30 * Changed the following headers to ROBODoc format:
32 lib/silccore/silcpayload.h
33 lib/silccore/silcprotocol.h
34 lib/silccore/silcsockconn.h
36 All core library headers are now formatted.
38 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
40 * Fixed a bug in Irssi SILC client; do not show that you are
41 server/router operator if you really are not. Affected file is
42 irssi/src/silc/core/client_ops.c.
44 * Renamed silc_command_free_payload to silc_command_payload_free.
45 Affected file lib/silccore/silccommand.h
47 * Added silcmath.h to include the prototoypes of various routines
48 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
51 * Changed the following headers to ROBODoc format:
53 lib/silccore/silcchannel.h
54 lib/silccore/silccommand.h
56 lib/silccore/silcidcache.h
57 lib/silccore/silcmode.h
58 lib/silccore/silcnotify.h
59 lib/silccore/silcpacket.h
60 lib/silcmath/silcmath.h
62 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
64 * Added checking to the server code not to start the server if
65 ciphers and stuff are not configured properly. Affected files
66 silcd/serverconfig.[h] and silcd/server.c.
68 * Changed the layout of the header files of the public interfaces
69 in the SILC libraries. The new layout supports ROBODoc
70 documentation tool (and some others) so that it is easy to create
71 a library reference manual. All the other headers and source
72 code must still follow the CodingStyle document. Also source
73 code must not include these ROBODoc stuffs, only the headers.
74 Furthermore, all public interface headers must now be named
75 by using `silc' prefix, example: silcapi.h, silccipher.h.
76 Some files were renamed due to this. All the other headers
77 must not be used as public interfaces. I will update the
78 CodingStyle document later. Changed following headers, so far:
80 lib/silcclient/silcapi.h
81 lib/silccore/silcauth.h
82 lib/silccore/silcprivate.h
83 lib/silccrypt/silcdh.h
85 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
89 * Removed silc_client_packet_send_flush from the client library
90 as it is not needed. Affected file lib/silcclient/client.[ch].
92 * Added printing of message of unresolved authentication method
93 to the Irssi SILC client. Added it to the module formats.
94 Removed the same message from the client library.
96 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * Added new distribution feature, DISTLABEL. Every distribution
99 can define own preprocessor label that can be used in the
100 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
101 file distributions, acconfig.h.pre and prepare.
103 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
105 * Added Makefile.defines_int to include the actual definitions
106 for Makefile.defines.in. Tested the new distribution system,
107 created distributions and tested installation.
109 * Added AWAY message printing to the Irssi SILC client. Added
110 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
112 * Added SCONNECT command to call the SILC's CONNECT command.
113 Cannot use CONNECT directly since Irssi uses that internally.
114 Affected file irssi/src/silc/core/silc-servers.c.
116 Added ACTION local command. It is same as ME command but takes
117 the channel as mandatory argument.
119 Rewrote some of the Irssi's help files to suite for SILC
122 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
124 * Added Makefile.defines[.in] that should for now on be included
125 in all Makefile.am file in the source tree. That file includes
126 all common compilation definitions for SILC source tree.
128 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
130 * Minor changes to the ./prepare script to change the package
131 name according the distribution name to the configure.in.
133 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
135 * Created new distribution system. Added file `distributions'
136 that defines all the distributions that can be created out of
137 the SILC source tree. The ./prepare script now reads that
138 file to determine how to prepare the distributions. The
139 first argument to the ./prepare is the name of the distribution
140 and second is the version of the distribution. If given
141 without arguments it creates the default (toolkit) distribution
142 with the default version (defined in ./prepare).
144 All Makefile.am files that are subject to the distributions
145 are now named as Makefile.am.pre. These are ./Makefile.am
146 and lib/Makefile.am. Others may be changed later.
148 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
150 * Added invite list, ban list, some key management and connection
151 error message printing to module formats in the Irssi SILC client.
153 * Added new silc_client_set_away_message to set the away message
154 that is back to the person who sent private message. The
155 affected file lib/silcclient/silcapi.h and the
156 lib/silcclient/client_prvmsg.c.
158 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
160 * Fixed the private message sending in the Irssi SILC client,
161 added local command KEY to the Irssi SILC client.
163 Added key management and key agreement message formats to the
164 irssi/src/fe-common/silc/module-formats.[ch].
166 Added USERS (alias WHO) printing, server/router operator
167 indication and LIST command printing to the module formats.
169 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
171 * Fixed channel joining notify handling, cumode notify handling
172 from Irssi SILC client.
174 * Added SILC specific module-formats to the Irssi SILC client so
175 that SILC specific message hilighting, colors etc is possible.
176 Affected file irssi/src/fe-common/silc/module-formats.[ch].
178 Added channel mode, channel user mode, actions, notices,
179 whois and whowas printing to the the module-formats.c.
181 * Fixed a bug in channel deletion in the server. The channel
182 is not left to the cache even if the channel founder auth mode
183 is set when there are no users anymore on the channel. Affected
186 * The silc_net_localhost now resolves the entire hostname including
187 the domain name. Affected file lib/silcutil/silcnet.c.
189 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
191 * Changed the ask_passphrase client operation to be ascynchronous.
192 It has now a completion callback and a context that the
193 application must call after it has got the passphrase from
194 the user. Affected files lib/silcclient/silcapi.h,
195 lib/silcclient/protocol.c, lib/silcclient/command.c and
198 Added SilcAskPassphrase callback that the application calls
199 to deliver the passphrase to the library.
201 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
202 The public key verification and especially a certificate
203 verification is asynchronous procedure.
205 Added new SILC_SKE_STATUS_PENDING status to indicate the
206 request is pending and a callback will be called to finalize
209 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
210 indicate that remote end did not send its public key (or
211 certificate), even though we require it. Added check for this
212 condition in the SKE. This was a security bug, now fixed.
214 Defined new SilcSKEVerifyCbCompletion callback that is called
215 when the verification process is completed.
217 The affected files lib/silcske/silcske_status.h and
218 lib/silcske/silcske.[ch].
220 * Changed the verify_public_key client operation to be async
221 as well. Defined SilcVerifyPublicKey callback that is used to
222 indicate the success of the public key verification process.
224 Changed the server and client to use the new async client
227 * Changed the Irssi SILC client's internal scheduler to be called
228 twice as many times as it used to be. As a result the client
229 should be a bit faster now. Affected file is
230 irssi/src/silc/core/silc-core.c.
232 * Added support to Irssi SILC client of asynchronous public key
233 verification and passphrase inquiry. Affected file is
234 irssi/src/silc/core/silc-core.c.
236 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
238 * Do not say "You have left channel %s" in client library.
239 Moved it to the application. Affected files are
240 lib/silcclient/command.c and silc/client_ops.c.
242 * Fixed silc_client_get_clients. Command context was not
243 duplicated and was freed memory in the callback. Affected
244 file lib/silcclient/idlist.c.
246 * Do not say "you are now talking..." on JOIN command in the
247 client library. The appliation must handle it.
249 * Do not say ".. changed topic to" in command reply in the
250 client libary. The application must handle it.
252 * Fixed TOPIC command sending in the client library.
254 * Fixed a memory leak in silc_client_command_free in the file
255 lib/silcclient/command.c.
257 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
259 * Imported a modified version of Irssi client to the source tree.
260 The Irssi will be used to create a new client called
261 Irssi SILC. Imported to irssi/.
263 Added silc_core_init_finish function to the Irssi. Affected
264 file irssi/configure.in.
266 A lot changes in the Makefile.ams around the irssi tree.
268 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
270 * Do not rehash if the new size is same as the old size of the
271 hash table, in the silc_hash_table_rehash*. The affected file
272 lib/silcutil/silchashtable.c.
274 * Replaced hash_table_del_by_context calls from the server
275 (when channel->user_list and client->channels) to the
276 hash_table_del as it is sufficient and faster.
278 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
280 * Added silc_hash_table_list, silc_hash_table_get and the
281 SilcHashTableList structure to provide an alternative way to
282 traverse the hash table. The affected files are
283 lib/silcutil/silchashtable.[ch].
285 * Changed the server's idlist routines to use the hash table
286 routines to optimize the code.
288 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
290 * Replaced the client entry's `channel' list and channel entry's
291 `user_list' list to hash tables for optimized lookup. Changed
292 the code to use the hash table interface around the code.
293 Affected file lib/silcd/idlist.[ch].
295 * Added `auto_rehash' boolean argument to the function
296 silc_hash_table_alloc to indicate whether the hash table should
297 auto-rehash when it thinks is appropriate time. It will
298 increase the hash table size if the there is twice as much
299 entries in the table than the size of the table, and will
300 decrease the size if there are twice as less entries than
301 the size of the table.
303 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
305 * Fixed silc_xxx_get_supported to not crash at some circumstances.
307 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
309 * silc_idcache_purge_by_context deletes the entry now by context
310 as it is supposed to do. Affected file lib/silccore/idcache.c.
312 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
313 client is not anymore valid (WHOWAS givens the info) and not
314 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
316 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * Removed the `data' and `data_len' arguments from the ID Cache
319 interfaces and added `name' argument. ID Cache does not handle
320 anymore the binary data only a names associated with given ID.
322 * When hashing a Client ID with silc_hash_id the entire ID is
323 not hashed anymore, instead only the hash of the Client ID is
324 hashed. This way we can access the Client ID from the cache
325 with Client ID but with the hash of the ID (which is a hash of
326 the nickname) as well without any difference in performance.
328 Added also silc_idcache_find_by_id_one_ext to do one on one
329 searching when we have the actual ID. Added also function
330 silc_hash_client_id_compare. The affected files are
331 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
333 * When hashing the name associated with a ID it is always done
334 in lowercase. This way we can access the cache without worrying
335 about case-sensitivity, even though, for example nicknames are
338 * Fixed a bug in server with channel message sending. It put
339 wrong ID type as destination ID. The affected file
342 * silc_idcache_del_by_context now deletes from all hash tables
343 by context. Affected file lib/silccore/idcache.c.
345 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
347 * Changed the client library to use the new ID Cache interface.
348 Changes around the source tree.
350 * Added silc_hash_table_rehash_ext to rehash with specific
351 hash function. Affected file lib/silcutil/silchashtable.[ch].
353 * Added silc_hash_string_compare to compare two strings in the
354 hash table. Affected file lib/silcutil/silcutil.[ch].
356 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * Added new function silc_idcache_del_by_context into the
359 lib/silccore/idcache.[ch].
361 * Changed the server's ID list routines to use the new ID Cache
362 interface. Changes around the source tree.
364 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
366 * Added silc_hash_table_del[_by_context]_ext functions in to the
367 lib/silcutil/silchashtable.[ch].
369 Removed silc_hash_table_find_all* routines and added new
370 silc_hash_table_find_foreach to replace them.
372 Added silc_hash_table_replace_ext function as extended
373 replacing function. Separated the simple hash table interface
374 from the extended hash table interface in the file
375 lib/silcutil/silchashtable.h.
377 * Fixed minor bugs and changed it to use some of the new
378 hash table functions in lib/silccore/idcache.c
380 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
382 * Added new function silc_hash_table_find_all to return all keys
383 in the hash table by the specified key. As the hash table is
384 collision resistant it also makes it possible to have several
385 duplicate keys in the hash table. This function may be used to
386 find all of the keys from the hash.
388 Added user_context arguments to the SilcHashFunction,
389 SilcHashCompare and SilcHashDestructor to deliver user specified
392 Added new fuctions silc_hash_table_find[_all]_ext to do
393 extended lookup with specified hash and compare functions and
394 specified user contexts.
396 Added new function silc_hash_table_add_ext to add the key
397 with specified hash function and user context.
399 Added new function silc_hash_table_foreach to traverse all
400 entrys in the hash table. Added SilcHashForeach callback
403 Added new function silc_hash_table_del_by_context to delete
404 the entry only if the context associated with the key matches.
406 Affected files are lib/silcutil/silchashtable.[ch].
408 * Removed silc_hash_[server/client/channel]_id and added just
409 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
410 silc_hash_id_compare to compare two ID's using as the hash table
411 comparison function. Added also silc_hash_data to hash
412 binary data and silc_hash_data_compare to compare it.
414 * Removed silc_idlist_find_client_by_hash as it is not needed
415 anymore. Affected file silcd/idlist.[ch].
417 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
418 to use internally the SilcHashTable. The new ID Cache is a lot
419 faster than the old one. Some of the ID Cache interface was also
420 rewritten and obsolete and stupid functions were removed.
422 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
424 * Added entry_count field to the SilcHashTable to keep the number
425 of the entries in the table. Implemented the function
426 silc_hash_table_rehash. Added new function
427 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
429 Fixed a minor bug in silc_hash_table_free.
431 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
432 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
433 into the lib/silcutil/silcutil.[ch].
435 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
437 * Implemented a collision resistant hash table into the
438 lib/silcutil/silchashtable[ch]. See the header and the source
439 for the SilcHashTable API.
441 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
443 * Merged dotconf version 1.0.2 into lib/dotconf.
445 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
447 * Do not compile anything in lib/silcsim/* if the SIM support
448 is not enabled. The tree should now compile without problems
451 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
453 * Compiled the SILC under cygwin. Compiled and tested briefly
454 without problems. More tests needed. The SIMs didn't compile
457 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
459 * Fixed possible crash in silc_get_username in the
460 lib/silcutil/silcutil.c.
462 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
464 * Fixed a va_arg in silc/client_ops.c.
466 * Oops, RC5 routines were named AES and caused some problems
467 when not using SIM's. Affected file lib/silccrypt/rc5.c.
469 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
471 * Added new SilcIDIP structure into the lib/silccore/id.h and
472 replaced the old `ip' fields from all SILC ID's to that type.
473 This is a step towards IPv6 support.
475 The silc_id_get_len takes now the ID as an extra argument.
476 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
477 both IPv4 and IPv6 based ID's.
479 The affected files are lib/silccore/id.[ch] and other files
480 around the tree using these routines.
482 * Removed the ID length arguments in server from various
483 silc_server_send_notify_* routines -> they are not needed
486 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
488 * Fixed memory leak in silc_encode_pem_file in the file
489 lib/silcutil/silcutil.c.
491 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Check minor version as well in the SKE. Affected files are
494 silcd/protocol.c and lib/silcclient/protocol.c.
496 * Added --identifier option to the server so that an identifier
497 can be when creating the public key for the server. Affected
498 file is silcd/silcd.c.
500 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
501 lib/silccrypt/silcpkcs.c.
503 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
505 * Register default ciphers and stuff when using -C option with
506 the server. Affected file sildc/silcd.c.
508 * Put back the servers public key filename format, it is better
509 than the new one. For now, the client keys are saved with the
510 new filename format. The affected file silc/client_ops.c.
512 * Implemented the Cipher API for the rest of the ciphers that
513 did not implement it or implemented it the wrong way.
515 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
517 * Register default ciphers and stuff when using the -S option
518 in the client. Affected file silc/silc.c. Same also when
519 creating new key pair with -C option.
521 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
523 * Fixed the silc_verify_public_key client operation function to
524 save the public keys differently. The fingerprint is now
525 used as filename and not the hostname. This way also the
526 client keys are saved uniquely and not with hostnames. The
527 affected file is silc/client_ops.c.
529 * Trimmed the silc_hash_fingerprint function to remove extra
530 whitespaces from the end of the fingerprint. The affected
531 file is lib/silccrypt/silchash.c.
535 * Added silc_cipher_register_default function to register all
536 default ciphers. It can be used when configuration files
537 does not exist and the application does not want any specific
538 ciphers in any specific order.
540 The SilcDList is now used as silc_cipher_list dynamically
541 allocated cipher list. Removed the static list all together
542 and now all ciphers must be allocated to the dynamic list.
543 The silc_cipher_alloc routine was changed to check only the
546 All silc_cipher_* routines that used to return int returns
549 The affected files lib/silccrypt/silccrypt.[ch].
551 * The same thing was done to silc_hash_* as for silc_cipher_*
552 routines. Affected files lib/silccrypt/silchash.[ch].
554 * The same thing was done to silc_pkcs_* as for silc_cipher_*
555 routines. Affected files lib/silccrypt/silcpkcs.[ch].
556 Added also silc_pkcs_[un]register[_default] functions.
557 Removed the data_context from the PKCS API.
559 * Added silc_hmac_register_default function to register default
560 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
561 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
562 to unregister all hmacs at once.
564 * Register the default ciphers, hash functions, PKCSs and HMACs
565 if client's configuration file does not exist. The affected
568 * The client did not load the hash functions from the SIM
569 modules at all. Added support for this. Affected file is
572 * When decoding public key with silc_pkcs_public_key_decode, check
573 the supported algorithm only if PKCS are registered. Affected
574 file lib/silccrypt/silcpkcs.c. The same was done with the
575 silc_pkcs_private_key_decode.
577 * Fixed the SILC List routines to keep the list always in order.
578 It used to change the list's order when traversing the list but
579 not it preserves the order. Affected file lib/trq/silclist.h.
581 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
583 * Added the client library to use the SilcSocketConnection's
584 reference counter (by silc_socket_dup) to prevent the bug that
585 the socket object may be freed underneath async operation.
587 * The name resolv library checking fixes in the configure.in.pre.
590 * Created new version of the protocol drafts for future
591 development. The -03 drafts are the ones that will be changed
592 in the trunk now and the -02 will remain as they are.
594 * Send list of CUMODE notifys to the router when announcing
595 the channel users to the router. Affected file silcd/server.c.
596 If the router receiving channel founder CUMODE for a channel
597 that already has channel founder it will send CUMODE notify
598 to the sender to remove the channel founder rights from the
599 announced client. Affected file silcd/packet_receive.c.
601 * The CUMODE notify may now use Server ID as well as the entity
602 who changes the mode. Updated protocool specs.
604 * Updated INSTALL and README files.
606 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
608 * New web pages in the http://silc.pspt.fi. The pages was
613 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
615 * Implemented the [DenyConnectin] config section in the server.
616 Added silc_server_config_denied_conn to check whether incoming
617 connection is denied. Affected file silcd/serverconfig.[ch].
619 * Do not check the ports when checking the incoming configuration
620 data if the port is 0, meaning any. Affected file is
621 silcd/serverconfig.c.
623 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
625 * Fixed buffer overflow in silc_string_compare in the file
626 lib/silcutil/silcutil.c.
628 * Fixed double free in silc_server_command_leave in the file
631 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
633 * Fixed the version checking in the server. Affected file is
636 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
638 * Fixed the configuration data fetching when accepting new
639 connections in the server. Affected file silcd/server.c.
641 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
643 * Added `sender_entry' argument to the function
644 silc_server_packet_relay_to_channel so that we can check
645 whether some destination actually belongs to the same route
646 the sender belongs (ie, we must not resend the packet to the
647 sender). Affected file silcd/packet_send.[ch].
649 * Added `servername' field to the SilcClientEntry in the server
650 to hold the name of the server where client is from. Affected
651 file is silcd/idlist.h.
653 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
655 * Moved the channel message encrypting in the router betwen
656 router connections from silc_server_channel_message to the
657 silc_server_packet_relay_to_channel since we want to check
658 whether we have anybody channel before encrypting anything.
659 Affected files silcd/packet_[receive/send].c.
661 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
663 * Fixed the [AdminConnection] server config section to support
664 multiple entries. Affected file silcd/serverconfig.c.
666 * Added support into the server to check the validity of the
667 incoming connection before executing any KE or authentication
670 * The connection configuration is now saved to the KE and
671 connection auth protocol contexts and not fetched anymore in
672 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
674 * The local hosts listenning address and port is also resolved
675 now when starting the server. We want to have the socket object
676 to include the real address and port for the listener. Added
677 new function silc_net_check_local_by_sock into the files
678 lib/silcutil/silcnet.[ch].
680 * Fixed a broadcast bug in server -> do not broadcast if we
683 * Fixed a routing bug. Do not route broadcast packets ever.
684 Broadcast packets must be processed always and not routed since
685 they may be destined to some other host than yourself and thus
686 would get routed without no good reason. Affected file is
689 * Added function silc_server_config_is_primary_route to check
690 whether primary router connection has been configured (a router
691 configuration that we are initiating). If there is not, we
692 will assume that there is only two routers in the SILC network
693 and we will use the incoming router connection as our primary
694 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
696 * Changed the order of the broadcasting. Broadcast _after_ the
697 packet has been processed not before. Affected file is
700 * Fixed a [ClientConnection] parsing bug. The port was never
701 parsed correctly thus resulting to port 0. Affected file
702 silcd/serverconfig.c.
704 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
705 argument and did not set the broadcast packet flag. Affected
706 file silcd/packet_send.c. Fixed same bug in the function
707 silc_server_send_notify as well.
709 * If we receive NEW_ID packet for our own ID in the server, ignore
712 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Removed the nickname from the Private Message Payload.
717 Updated the code and the protocol specs.
719 * Updated protocol specs for submitting to the IETF.
721 * Tweaked the Random Number Generator a bit. Affected file
722 lib/silccrypt/silcrng.c. Exported a new function
723 silc_rng_[global]_add_noise which can be used to add more
726 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
728 * Do not parse packets with different timeout when protocol
729 is active -> may cause problem with rekey. Affected file
732 * When server receives signoff notify it must not create
733 new channel key if the client is on any channels since the
734 sender of the signoff notify will create it.
736 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
738 * Added printing of error messages during SKE protocol from the
739 failure packet sent by server during SKE. Affected file
742 * Removed the client's failure_callback handling with timeout
743 and handle it immediately when received.
745 * The SKE library returned wrong type in SUCCESS and FAILURE
746 packets. They must be 32 bit MSB not 16 bit MSB.
748 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
750 * Ok, rewrote the logic of the re-key and now it seems to work.
751 I tested it on high traffic with frequent re-keys without
752 problems. Added hmac_receive (and renamed hmac to hmac_send)
753 in SilcClientConnection in lib/silcclient/client.h and
754 in SilcIDListData in silcd/idlist.h. Also, removed the
755 SilcPacketParserContext's cipher and hmac fields as they are
756 not needed anymore and actually caused some problems when
757 the ciphers and hmac's changed underneath the packet parser.
759 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * If re-key protocol is active then process the incoming packets
762 synchronously since we must assure that icoming packets encrypted
763 with the old key is processed before the new keys is set to
764 use. This is true other packets than for REKEY packets.
765 Affected file silcd/server.c. The same was done to client library
766 as well, affected file lib/silcclient/client.c.
768 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Fixed bug in client and server to accept the force send if
771 the packet is send from silc_[server/client]_packet_process
772 function. Otherwise the packets are never delivered, oops.
774 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * Disable force sending of packets when REKEY protocol is active.
777 We must assure that no packet is sent directly when rekey is
778 performed. All packets must be sent through packet queue.
779 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
780 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
781 function is silc_[server/client]_packet_send_real to check
784 * Replaced the SIM paths from example config files to
785 /usr/local/modules. Also, make install creates now
786 /usr/local/silc/logs directory to hold all the SILC server
789 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
791 * Made the configure.in.pre work on Solaris. Patch by salo.
793 * Made all ciphers compatible with non-x86 machines. Defined
794 CBC mode macros into lib/silccrypt/ciphers_def.h.
796 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
798 * Fixed the make install.
800 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
802 * When MAC computation fails the silc_packet_decrypt returned 0
803 even though it was supposed to return -1. Fixed this. The
804 affected file is lib/silccore/silcpacket.c.
806 * Do not replace the config files in /etc/silc (in make install)
807 if they already exist. Affected file ./Makefile.am.
809 * Do not send re-key packets immediately but through packet queue.
810 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
812 * Changed silc_net_check_host_by_sock to return FALSE if the
813 IP/DNS could not be resolved. Though, it returns the IP address
814 now even if it could not resolve it (but returns also FALSE).
815 Affected file lib/silcutil/silcnet.[ch].
817 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
819 * Added silc_pkcs_decode_identifier to decode the public key's
820 identifier. Affected file lib/silccrypt/silpkcs.[ch].
821 Added also silc_pkcs_free_identifier. Added also new context
822 SilcPublicKeyIdentifier.
824 * Added -S option to the silc client. It is used to dump the
825 contents of the specified public key file.
827 * Changed the PKCS api to return the public key length when
828 setting the public key.
830 * Fixed a fatal bug in the public and private key file loading.
831 Affected file lib/silccrypt/silcpkcs.c.
833 * Execute the packet parsing for client with zero (0) timeout
834 if the protocol is active. Affected file silcd/server.c.
836 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
838 * Made the key generation options to the silcd program. Added
839 -C option, equivalent to client's option.
841 * Added new [ServerKeys] config section to the server. It
842 configures the server's public and private key.
844 * Defined generic Public Key Payload into the protocol
845 specification to send specific type of public keys and
848 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
849 public key or certificate.
851 * Implemented the GETKEY command to the server and to the
852 client library and on user interface.
854 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
856 * Made preliminary `make install' work.
858 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
860 * Added SilcServerRekey context into silcd/idlist.h.
862 * Added the PFS support as defined in the specification to the
863 SKE protocol. Affected files lib/silcske/*.c.
865 * Added `ske_group' field to the SilcServerRekey context to hold
866 the number of the SKE group that is used with PFS in re-key.
867 Affected file silcd/idlist.h.
869 * Added PFS re-key support to the server. Affected file is
872 * Added silc_protocol_cancel to cancel execution of the next
873 state of the protocol. Affected file is
874 lib/silccore/silcprotocol.[ch].
876 * Added the re-key support with and without PFS to the client
877 library. Re-key is performed once in an hour, by default.
879 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
880 Added silc_client_rekey_callback and silc_client_rekey_final.
881 Affected files are lib/silcclient/protocol.[ch] and
882 lib/silcclient/client.[ch].
884 * Removed the `hmac_key' and `hmac_key_len' fields from the
885 SilcClientConnection structure; not needed. Affected file is
886 lib/silcclient/client.h.
890 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
892 * Do not ask whether user wants to use the negotiated private key
893 for private messages, just use it. Affected file is
894 silc/local_command.c.
896 * Added `send_enc_key' and `enc_key_len' fields to the
897 SilcIDListData structure since they are needed in the re-key
898 phase. Affected file is silcd/idlist.[ch].
900 * Implemented the simple re-key protocol into the server.
901 Affected files silcd/server.c and silcd/protocol.[ch]. The
902 re-key will be performed once in an hour, by default.
904 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
905 Added silc_server_rekey, silc_server_rekey_callback and
906 silc_server_rekey_final.
908 * Removed Tunneled flag from the protocol. Updated the code
909 and the specifications.
911 * Adde `pfs' field to the SilcIDListData to indicate whether
912 the PFS is to be performed in the re-key. Affected file is
915 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
917 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
918 int64 of at least the xintXX size. If void * is less that 4
919 bytes uint32 * will be used. Defined bool as boolean.
921 * Changed _ALL_ unsigned long and unsigned int to uint32,
922 unsgined short to uint16 in the source tree.
924 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
925 not handle clients that has entry->data.registered == FALSE.
926 They are not in the network anymore. Affected file is
929 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
931 * Implemented the sending of the SERVER_SIGNOFF notify in the
932 server. Affected file is silcd/server.c.
934 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
935 Added also silc_notify_payload_encode_args into the
936 lib/silccore/silcnotify.[ch].
938 * Implemented ther SERVER_SIGNOFF notify handling in the server.
939 Affected file silcd/packet_receive.c.
941 * Implemented the SERVER_SIGNOFF notify handling in the client
942 library. Affected file lib/silcclient/client_notify.c. Also,
943 implemnted the printing of the SERVER_SIGNOFF info to the
944 application. Affected file silc/client_ops.c.
946 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
947 if the deleting was successful. Affected file silcd/idlist.[ch].
949 * Added support for public key authentication in the connection
950 authentication protocol in the client library. Affected file
951 lib/silcclient/protocol.c.
953 * Changed the server's silc_idlist_get_clients_by_* interface
954 to support already allocated array so that new entries may be
955 added to pre-allocated array. Affected file silcd/idlist.[ch].
956 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
959 * All command reply functions in the server now calls the
960 pending command callback even if error occured. This way the
961 error will be delivered to the client as well. Affected files
962 silcd/command.c and silcd/command_reply.c.
964 * Fixed INFO command to return local server's info if no server
965 was provided. Affected file lib/silcclient/command.c.
967 * Removed RESTART command for good. Updated the code and the
970 * Rewrote parts of the task system. It is a bit simpler now.
971 Removed unsued task priorities. The affected files are
972 lib/silcutil/silctask.[ch].
974 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
976 * Moved the USERS printing from the library to the application.
977 Affected files lib/silcclient/command.c and silc/client_ops.c.
979 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
983 * Added channel key re-key support. The re-key is perfomed
984 only by the router and is done once in an hour. Added `rekey'
985 field to the SilcChannelEntry in the server. Affected files
986 silcd/server.c and silcd/idlist.h.
988 * Added silc_task_unregister_by_context into the file
989 lib/silcutil/silctask.[ch].
991 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Added SILC_UMODE_GONE mode to indicate when the client is not
994 present in the SILC network. Added also support to the local
995 command AWAY that will set this mode. Added support of showing
996 "xxx is gone" in WHOIS command. The USERS command shows the
999 * Fixed setting server and router operator privileges in the
1000 server's UMODE command. Affected file silcd/command.c.
1002 * Merged the SKE KE1 and KE2 payloads into one payload. The
1003 new KE payload is equivalent to the old KE2 payload.
1005 Cleaned up the SKE Start Payload parsing. It now uses the
1006 simple buffer unformatting to do the parsing. A lot faster
1009 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1010 to the SKE that is used to indicate whether both of the SKE
1011 parties should perform authentication. By default only the
1012 responder performs authentication. By setting this flag also
1013 the initiator must do authentication. By default it is unset
1014 since in normal SKE case, client to server connection, only
1015 the responder should do authentication. When doing SKE between
1016 two clients both should perform authentication. Updated the
1017 code and the protocol specs.
1019 * A little fix to IDENTIFY command in the server. Search the
1020 client first by hash not nickname. Affected file is
1023 * Fixed the silc_client_close_connection to support closing
1024 the client to client connections wihtout deleting too much
1025 data. Affected file lib/silcclient/client.c.
1027 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1028 are received if protocol used to be active but is not anymore
1029 the application would crash due to NULL pointer dereference.
1030 Affected files silcd/server.c and lib/silcclient/client.c.
1032 * Added `hash' field to the SilcClientConnection to include
1033 the hash function negotiated in the SKE protocol.
1035 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1036 to set the channel founder authentication data. A client can
1037 claim the founder rights later by providing the authentication
1038 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1039 This way the channel founder can regain the channel founder
1040 privileges even it is left the channel. This works only on
1041 local server and the client must be connected to the same
1042 server to be able to regain the founder rights. Updated the
1043 protocol specs accordingly.
1045 Added support to the CMODE command in the client to set the
1046 founder auth data. Read the README to see how to set it.
1048 Added support to the CUMODE command to claim the founder
1049 rights. Read the README to see how to do it.
1051 Added support for the founder authentication to the Channel
1052 Entry in the server. Affected file silcd/idlist.h.
1054 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1055 server's CMODE command. Affected file silcd/command.c.
1057 * Added the following new functions into lib/silccore/silcauth.[ch]:
1058 silc_auth_get_method and silc_auth_get_data.
1060 * The server now saves the remote hosts public key to the
1061 SilcIDListData pointer. Affected file silcd/protocol.c.
1063 * The normal server now does not remove the channel entry from
1064 the cache if the founder authentication data is set. It used
1065 to remove it if the founder was the last one on the channel on
1066 the server and left the channel. The auth data is saved and
1067 if the channel is re-joined later the old entry is used with
1068 the old auth data. Affected files silcd/command_reply.c and
1071 * Removed the `pkcs' field from the SilcIDListData structure
1072 in the server; it is not used. Affected file silcd/idlist.h.
1074 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1076 * Fixed packet processing on slow links. Partial packets were
1077 never re-processed because the incoming data buffer was cleared
1078 by the application. Application must not directly clear the
1079 sock->inbuf, the packet processing routines handle it. Fixed
1080 this in client library and in server.
1082 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1084 * Fixed the WHOIS and IDENTIFY send reply function to really
1085 check whether to send list or just one entry. Affected file
1088 * Cleaned up the LEAVE command's channel key distribution. The
1089 affected file silcd/command.c.
1091 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1092 can enforce the channel mode as well. In that case the ID
1093 includes the ID of the server. The code now enforces the
1094 mode change if the router have different mode than the server.
1096 * The notify client operation with CMODE_CHANGE notify can now
1097 return NULL client_entry pointer if the CMODE was not changed
1098 by client. Application must check for this.
1100 * Added <Server ID> argument to INFO command to support server
1101 info fetching by Server ID.
1103 * Added silc_server_announce_get_channel_users to get assembled
1104 packets of channel users of the specified channel. Affected
1105 file silcd/server.[ch].
1107 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1108 was freed underneath the ID Cache.
1110 * Re-announce clients when the server received CHANNEL_CHANGE
1111 notify from the router. Affected file silcd/packet_send.c.
1113 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1115 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1116 crashed since it did not handle the fact that there is no cipher
1117 called "3" and didn't check the error condition. Now fixed.
1119 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1120 flag. It can be used to send message requests.
1122 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1124 * Implemented the RESTART command in the client.
1126 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1127 notice type messages. Added notice printing to the user
1130 * The channel keys are not re-generated if the channel's mode
1131 is PRIVKEY, ie private key on the channel exists. Affected
1132 files silcd/server.c and silcd/command.c.
1134 * Fixed a little bug in channel message delivery when channel
1135 private keys are set in the server. Affected file is
1136 silcd/packet_send.c.
1138 * Changed the setting on channel->on_channel = TRUE from the
1139 silc_client_save_channel_key to the JOIN command reply. The
1140 key payload is not received if the private channel key is set.
1141 Affected file lib/silcclient/command_reply.c and the
1142 lib/silcclient/client_channel.c.
1144 * When the CMODE_CHANGE notify is sent and the channel private
1145 key mode is removed the channel key must be re-generated in
1146 other cells as well. Added this support for the router in the
1147 silcd/packet_receive.c.
1149 * Added new local command NOTICE to send notice message on
1150 channel. Affected file silc/local_command.[ch].
1152 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Added new local command ME to the client. It is used to send
1155 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1156 some action. Affected file silc/local_command.[ch].
1158 * Changed channel_message and private_message client operations
1159 to deliver the message flags to the application. Added also
1160 the `flags' arguments to the silc_client_send_channel_message
1161 and silc_client_send_private_message functions. Affected file
1164 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1166 * Redefined the Private Message Payload to support private message
1167 keys and to support the new private message flags. Updated
1168 the protocol specs. Flags makes it possible to have for example
1169 CTCP style messages.
1171 * Added new type SilcPrivateMessagePayload and defined an API
1172 for it in the lib/silcclient/silcprivate.[ch].
1174 * Tested private message private keys successfully. Tested the
1175 private message key set, unset and list commands with the new
1178 * Redefined the Channel Message Payload to include the channel
1179 message flags (equal with private message flags) to support
1180 for example CTCP style messages.
1182 * Defined some of the message (for channel and private message)
1183 flags. Updated the protocol specs and added the flags to the
1184 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1186 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1188 * Added SilcKeyAgreementStatus type to the key agreement routines
1189 to indicate the current status and error if one occured.
1190 The status types are defined in the lib/silcclient/silcapi.h.
1192 * Added new local command KEY that is used to set and unset private
1193 keys for channels, set and unset private keys for private messages
1194 with remote clients and to send key agreement requests and
1195 negotiate the key agreement protocol with remote client. The
1196 key agreement is supported only to negotiate private message keys,
1197 it currently cannot be used to negotiate private keys for channels,
1198 as it is not convenient for that purpose.
1200 * Fixed a minor pending callback setting bug in the function
1201 silc_client_get_client_by_id_resolve, now the function works.
1202 Affected file lib/silcclient/idlist.c.
1204 * Added function silc_net_get_local_port to get local bound
1205 port by socket. Added to lib/silcutil/silcnet.[ch].
1207 * Added `sockets' and `sockets_count' fields to the SilcClient
1208 object. They hold the sockets of the listenning sockets in
1209 the client. Listenning sockets may be for example the key
1210 agreement server. Affected file lib/silcclient/client.[ch].
1211 Added functions the silc_client_add_socket and the
1212 silc_client_del_socket. They are exported to the application
1215 * Added ~./silc/clientkeys to support other client's public keys.
1217 * Renamed verify_server_key client operation to verify_public_key
1218 and added one argument to indicate the type of the connection
1219 (server, client etc.).
1221 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1223 * Added silc_server_connection_auth_request to handle the
1224 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1225 silcd/packet_receive.[ch].
1227 * Added silc_server_send_connection_auth_request into the
1228 silcd/packet_send.c to send the connection auth request packet.
1230 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1233 * Fixed the public key authentication in responder side in the
1234 server. The `auth_data' pointer includes the SilcPublicKey
1235 not the path to the public key. Affected file silcd/protocol.c.
1237 * Implemented the public key authentication in the initiator side
1238 in the server. Affected file silcd/protocol.c.
1240 * Removed the [RedirectClient] config section from the server
1241 configuration. Is not needed and I don't want to implement it.
1243 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Cleaned up the CMODE command in the server. It now works
1246 correctly and supports all the modes defined in the protocol.
1247 Affected file is silcd/command.c.
1249 * Added `hmac_name' field to the SilcChannelEntry in the server
1250 to hold the default HMAC of the channel. It can be set when
1251 creating the channel (with JOIN command). Affected files
1254 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1255 type to indicate the change of the current cipher and hmac
1256 on the channel. Client can safely ignore the <cipher> argument
1257 (if it chooses to do so) since the CHANNEL_KEY packet will
1258 force the channel key change anyway. The <hmac> argument is
1259 important since the client is responsible of setting the new
1260 HMAC and the hmac key into use.
1262 * Fixed the CMODE command in the client library as well.
1264 * Tested CMODE command in router environment successfully.
1266 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Show the version of the remote client (or server) when connecting
1269 to the server. It is logged to the log file. Affected file
1270 is silcd/protocol.c.
1272 * Fixed the KILLED notify handling in the client library. The
1273 client must be removed from all channels when receiving the
1276 Also, do not remove the client entry when giving the KILL
1277 command but when the KILLED notify is received.
1279 * Removed silc_idlist_find_client_by_nickname from the server.
1280 Not needed anymore. Affected files silcd/idlist.[ch].
1282 * Implemented the CHANNEL_CHANGE notify type handling to the
1283 server. Affected file silcd/server.c.
1287 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Added silc_server_send_notify_invite to send the INVITE
1290 notify between routers.
1292 * Implemented the INVITE command correctly to the server.
1294 * Implemented the INVITE notify type handling in the server.
1296 * Implemented the INVITE command to the client library and on the
1299 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1301 * Added function silc_server_get_client_resolve to find the
1302 client entry by ID from all ID lists and then resolve it
1303 (using WHOIS) if it cannot be found. Affected file is
1306 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1308 * Implemented the BAN command to the client library.
1310 * The JOIN command in the server now checks the invite list
1313 * Changed the silc_command_reply_payload_encode_va and the
1314 silc_command_payload_encode_va to support that if argument is
1315 NULL it ignores and checks the next argument. Affected file
1316 lib/silccore/silccommand.c.
1318 * Added silc_server_send_notify_ban to send the BAN notify
1319 type between routers.
1321 * Chaned the silc_notify_payload_encode to support that if
1322 argument is NULL it ignores and checks the next argument.
1323 Affected file lib/silccore/silcnotify.c.
1325 * Tested ban lists in router environment successfully.
1327 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1329 * Implemented BAN command to the server, in silcd/command.[ch].
1331 * Removed the BAN and INVITE_LIST modes from the CMODE command
1334 * Added function silc_string_match to regex match two strings.
1335 Affected files lib/silcutil/silcutil.[ch].
1337 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1339 * Redefined parts of the SilcChannelEntry in the server to support
1340 the new ban and invite lists.
1342 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1344 * Redefined the INVITE command. The same command can be used to
1345 invite individuals to the channel but also to manage the invite
1346 list of the channel (to add to and remove from the invite list).
1347 Updated the protocol specs.
1349 * Added new command SILC_COMMAND_BAN that can be used to manage
1350 the ban list of the channel. Updated the protocol specs.
1352 * Removed the channel modes: the SILC_CMODE_BAN and the
1353 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1354 in the CMODE command. The equivalent features are now available
1355 using INVITE and BAN commands. Updated the protocol specs.
1357 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1358 in the network about change in the current ban list. The notify
1359 type is not used by the client.
1361 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1362 support the invite lists.
1364 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1366 * Added new function silc_string_regexify that converts string
1367 including wildcard characters into regex string that can
1368 be used by the GNU regex library. Added into the file
1369 lib/silcutil/silcutil.[ch].
1371 Added silc_string_regex_combine to combine to regex strings
1372 into one so that they can be used as one regex string by
1373 the GNU regex library. Added into the file
1374 lib/silcutil/silcutil.[ch].
1376 Added silc_string_regex_match to match two strings. It returns
1377 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1379 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1381 * Imported GNU regex to the soruce tree into lib/contrib.
1382 Fixed some compiler warning from the regex.c.
1384 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1386 * Fixed MOTD command in the server to work in router environment.
1388 * Fixed the MOTD command in the client library to support
1389 the server argument in the command.
1391 * Added `nickname_len' argument to the silc_idlist_add_client
1392 in the server, as the `nickname' argument may be binary data
1395 * Added silc_idlist_get_channels to return all channels from
1398 * Implemented LIST command to the server. Affected file is
1401 * Implemented the LIST command to the client library and on the
1404 * Added [<user count>] argument to the LIST command reply.
1405 With private channels the user count is not shown.
1407 * Updated TODO and README.
1409 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1411 * The client entry's data.registered must be TRUE even with
1412 global client entry on global client list. The data.registered
1413 is used to check whether the client is anymore in the network,
1414 for example with WHOWAS command so it must be valid.
1416 * Fixed the WHOWAS command in the server. It now actually works
1417 in router environment. Added function into silcd/command_reply.c
1418 silc_server_command_reply_whowas_save.
1420 * Added silc_idlist_purge function to the silcd/idlist.c
1421 to periodically purge the ID Cache.
1423 * Fixed INFO command in the server. It works now in router
1424 environment. Added <server name> argument to the INFO command
1425 reply. Updated the protocol specs.
1427 * Fixed minor bug in silc_idcache_purge to not purge if the
1428 expire value is zero.
1430 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1431 they were buggy because of the WHOWAS information.
1433 * Fixed local command MSG to handle the async resolving of
1434 the remote client properly. It used to fail the first MSG.
1435 Affected file silc/local_command.c.
1437 * Added `data_len' field to SilcIDCache context.
1439 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1441 * Update TODO. Todo in commands in the server.
1443 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1445 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1446 used by routers as broadcast packet to inform other routers
1447 about the changed user mode.
1449 Implemented the notify handling in the server. Affected file is
1450 silcd/packet_receive.c. Added the function
1451 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1453 * Added new generic Channel Payload and deprecated the New Channel
1454 Payload. The New Channel Payload is now the generic Channel
1457 * Added new argument `mode' to the silc_server_send_new_channel
1458 as it is required in the Channel Payload now.
1460 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1461 and created a new and real SilChannelPayload to represent the
1462 new generic Channel Payload. Implemented the encode/decode
1463 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1465 * Added silc_server_get_client_channel_list to return the list
1466 of channels the client has joined for WHOIS command reply.
1467 Affected file silcd/server.[ch].
1469 * Implemented the channel list sending in the WHOIS command reply
1470 in server and in the client.
1472 Implemented the channel list displaying on the user interface
1473 as well. Affected file silc/client_ops.c.
1475 * Added silc_channel_payload_parse_list to parse list of Channel
1476 Payloads. It returns SilcDList list of SilcChannelPayloads.
1477 Client for example can use this function to parse the list of
1478 channels it receives in the WHOIS command reply. The caller
1479 must free the list by calling silc_channel_payload_list_free.
1480 Affected files lib/silccore/silcchannel.[ch].
1482 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1484 * Added one new argument <user mode> to the WHOIS command reply
1485 to return the mode of the user in SILC. Updated the protocol
1488 Implemented it to the server and client.
1490 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1492 * Fixed the mode printing on the user interface on joining.
1493 Affected file silc/client_ops.c.
1495 * Implemented the UMODE command and user modes in general to the
1496 client library and to the user interface.
1498 * Implemented the UMODE command to the server.
1500 * The server now sends UNKNOWN_COMMAND error status if client sends
1501 unknown command. Affected file silcd/command.c.
1503 * All server commands now handle the command identifier the right
1504 way when sending the command reply to the client. The client can
1505 use to identify the command replies with the identifier.
1507 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1509 * Added silc_server_get_client_route to resolve the route to
1510 the client indicated by the client ID. Affected file is
1513 * Added silc_server_relay_packet as general function to relay
1514 packet to arbitrary destination. This deprecates functions
1515 like _send_private_message_key, _relay_notify etc. Affected
1516 file is silcd/packet_send.[ch].
1518 Removed silc_server_send_key_agreement,
1519 silc_server_send_private_message_key and
1520 silc_server_packet_relay_notify functions from the file
1521 silcd/packet_send.[ch].
1525 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1526 server. Affected file silcd/packet_receive.[ch].
1528 * Implemented the KILL command to the client. Implemented the
1529 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1530 Affected files lib/silcclient/command[_reply].c and
1531 lib/silcclient/client_notify.c. Implemented the KILL notify
1532 printing in the user inteface.
1534 * Fixed a lot silc_parse_nick memory leaks from the client
1535 library in the file lib/silcclient/command.c.
1537 * Changed the silc_server_send_notify_on_channels's `sender'
1538 argument from SilcSocketConnection to SilcClientEntry to
1539 check the sender as entry and not as connection object and not
1540 to send to the client provided as argument. The affected file
1541 is silcd/packet_send.[ch].
1543 * The notify packets that are destined directly to the client used
1544 to not to be processed by the server. Now changed that and the
1545 server processes all notify packets. After relaying the packet
1546 to the client the notify packet is processed in the server.
1548 * The silc_server_free_client_data now checks whether there is
1549 pending outgoing traffic for the client and purges the data to
1550 the network before removing the client entry.
1552 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1554 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1555 an client is killed from the SILC Network. Updated the protocol
1558 Added new function silc_server_send_notify_killed to the
1559 silcd/packet_send.[ch].
1561 * Added function silc_server_packet_relay_notify to relay notify
1562 packets that are destined directly to a client. In this case
1563 the server does not process the notify packets but merely relays
1564 it to the client. Affected file silcd/packet_send.[ch].
1566 Added also silc_server_packet_process_relay_notify to check
1567 whereto relay the notify. Affected file is
1568 silcd/packet_receive.[ch].
1570 * Implemented the KILL command to the server.
1574 * Added the backup schema desgined last fall to the protocol
1575 specs for everyone to see. The specification is in the
1576 *-spec-xx.txt draft and the packet type definitions for the
1577 backup routers is in *-pp-xx.txt draft. Thusly, added also
1578 new packet type SILC_PACKET_CELL_ROUTERS.
1580 * A big security problem in the implementation discovered. The
1581 signoff of an client did not cause new channel key generation
1582 which it of course should've done. The channel keys must be
1583 always re-generated when client leaves (or signoffs) the channel.
1584 The silc_server_remove_from_channels funtion now handles
1585 the channel key re-generation.
1587 * Added `sender' argument to the silc_server_send_notify_on_channels
1588 to not to send the client provided as argument. Affected file
1589 silcd/packet_send.[ch].
1591 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Implemented OPER and SILCOPER commands into the server and
1596 * Added silc_auth_verify and silc_auth_verify_data to verify
1597 the authentication directly from the authentication payload.
1598 It supports verifying both passphrase and public key based
1599 authentication. Affected file lib/silccore/silcauth.[ch].
1601 * Added `hash' field to the SilcIDListData structure. It is the
1602 hash negotiated in the SKE protocol. Affected file is
1605 * Slight redesigning of the SilcAuthPayload handling routines.
1606 Do not send SilcPKCS but SilcPublicKey as argument.
1608 * Implemented the public key authentication support to the
1609 serverconfig. The public key is loaded from the provided path
1610 and saved as authentication data to void * pointer. Thus,
1611 changed the unsigned char *auth_data to void *auth_data;
1613 * Fixed SHUTDOWN command to send the reply before the server
1614 is shutdown. :) Affected file silcd/command.c.
1616 * Fixed fatal bug in CONNECT command. The hostname was invalid
1617 memory and server crashed. Affected file silcd/command.c.
1619 * Fixed fatal bug in CLOSE command. The server_entry became
1620 invalid but was referenced later in the command. Affected file
1623 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1625 * Fixed fatal bug in failure packet handling. Server ignored
1626 the failure and thus crashed when it came.
1630 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1632 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1633 that the command may be executed only once in (about) 2 seconds.
1634 The old SILC_CF_LAG flag is same but allows command bursts up
1635 to five before limiting.
1637 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1638 server code. Various commands now includes the CF_LAG_STRICT
1639 flag to disallow any kind of miss-use of the command.
1641 * Fixed the silc_buffer_unformat to not to allocate any data
1642 if the length of the data is zero. It used to allocate the
1643 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1645 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1647 * Changed the format of AdminConnection configuration section
1648 in the server. Added username of the admin to the format.
1649 Affected files silcd/serverconfig.[ch].
1651 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1652 to return admin configuration data by host, username and/or
1655 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1657 * Implemented WHOWAS command to the server. Added the functions:
1659 silc_server_command_whowas_parse,
1660 silc_server_command_whowas_send_reply,
1661 silc_server_command_whowas_from_client and
1662 silc_server_command_whowas_from_server
1664 * Added <Client ID> argument to the WHOWAS command reply. Updated
1665 the protocol specs accordingly.
1667 * Implemented WHOWAS command and command_reply to the client
1670 Implemented the WHOWAS printing on the user interface.
1672 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1674 * Added new argument to the WHOWAS command reply, the real name.
1675 It is an optional argument. Updated the protocol specs.
1677 * Added SilcIDCacheDestructor callback that is registered when
1678 the SilcIDCache is allocated. The callback is called when
1679 an cache entry in the ID Cache expires, or is purged from the
1680 cache. Added into lib/silccore/idcache.[ch].
1682 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1683 to destruct the client entries when the cache entry expires.
1684 Other ID Cache's in server and in the client library ignores
1687 * If the ID Cache entry's `expire' field is zero then the entry
1688 never expires. Added boolean `expire' argument to the
1689 silc_idcache_add function in the lib/silccore/idcache.[ch].
1690 If it is TRUE the default expiry value is used.
1692 * Added silc_server_free_client_data_timeout that is registered
1693 when client disconnects. By default for 5 minutes we preserve
1694 the client entry for history - for WHOWAS command.
1696 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1698 * Added support to the server to enforce that commands are not
1699 executed more than once in 2 seconds. If server receives
1700 commands from client more frequently, timeout is registered
1701 to process the commands. Affected file silcd/command.c.
1702 Added new function silc_server_command_process_timeout.
1704 * Changed NICK_NOTIFY handling in client library to check that
1705 if the client's nickname was changed, so there is no need to
1706 resolve anything from the server.
1708 * Removed error printing from the WHOIS and IDENTIFY commands.
1709 If error occurs then it is ignored silently in the client library.
1710 The application, however, may map the received error to
1711 human readable error string. The application currently maps
1712 the NO_SUCH_NICKNAME error to string.
1714 * Made the command status message public to the application. Moved
1715 them from lib/silcclient/command_reply.c to
1716 lib/silcclient/command_reply.h. The application can map the
1717 received command status to the string with the
1718 silc_client_command_status_message function.
1720 * Added check to the server to check that client's ID is same
1721 as the Source ID in the packet the client sent. They must
1724 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Added dist-bzip hook to the Makefile.am to make bzip2
1727 compressed distributions.
1729 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1731 * Server now enforces the maximum length for the nickname and
1732 the channel as protocol specification dictates. 128 bytes for
1733 nickname and 256 bytes for channel name.
1735 * Moved the WHOIS printing to the application. The client libary
1736 does not print out the WHOIS information anymore, the application
1737 must do it. Renamed silc_client_command_reply_whois_print to
1738 the silc_client_command_reply_whois_save.
1740 The client's idle time is also sent to the application now, and
1741 the idle is shown on screen.
1743 * Added silc_client_command_reply_identify_save to save the
1744 received IDENTIFY entries.
1746 * Do not check for channel private keys in message sending and
1747 reception if the channel does not have the PRIVKEY mode set.
1748 Affected file lib/silclient/client_channel.c.
1750 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1752 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1753 just surfaced after chaning the JOIN procedure.
1755 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1757 * Added silc_client_get_clients_by_list to get client entries
1758 from Client ID list, that is returned for example by JOIN
1759 and USERS command replies. The application should use this
1760 function for example when JOIN command reply is received to
1761 resolve the clients already on the channel (library does not
1762 do that anymore as USERS command reply is not used in the JOIN
1763 procedure anymore). Affected files lib/silcclient/silcapi.h and
1764 lib/silcclient/idlist.c.
1766 * JOIN command reply and USERS command reply returns now SilcBuffer
1767 pointers instead of unsigned char pointers when returning
1768 the client list and mode list.
1770 * Added <Client ID> argument to the JOIN command reply, mainly
1771 for the server to identify for which client the command was
1772 originally sent. Updated protocol specs accordingly.
1774 * Added SilcDlist private_key pointer to the SilcChannelEntry
1775 in the client to support the channel private keys. Affected
1776 file is lib/silcclient/idlist.h.
1778 * Added SilcChannelPrivateKey argument to the function
1779 silc_client_send_channel_message so that application can choose
1780 to use specific private ke if it wants to. If it is not provided,
1781 the normal channel key is used, unless private keys are set.
1782 In this case the first (key that was added first) is used
1783 as the encryption key.
1785 * Implemented the support for channel private key handling.
1786 Implemented the following functions:
1788 silc_client_add_channel_private_key,
1789 silc_client_del_channel_private_keys,
1790 silc_client_del_channel_private_key,
1791 silc_client_list_channel_private_keys and
1792 silc_client_free_channel_private_keys
1794 Affected file lib/silcclient/client_channel.c.
1796 * Added the support for the private keys in the channel message
1797 sending and encryption and in the message reception and
1798 decryption. Affected funtions are
1799 silc_client_send_channel_message and silc_client_channel_message.
1801 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1803 * Added SKE's key verify callback to the client library's
1804 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1806 * Removed the statement that server (or router) must send USERS
1807 command reply when joining to the channel so that the client
1808 knows who are on the channel. Instead, the client list and
1809 client's mode list is now sent in the JOIN command reply to the
1810 client who joined channel. This is better solution.
1812 * Added function silc_server_get_users_on_channel and function
1813 silc_server_save_users_on_channel to the silcd/server.[ch].
1815 * Removed function silc_server_command_send_users from the
1818 * Do not show topic on the client library anymore. The topic is
1819 sent in the command reply notify to the application and the
1820 application must show the topic now.
1822 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Added client searching by nickname hash into the IDENTIFY and
1825 WHOIS commands in the server as they were clearly missing from
1826 them. Affected file is silcd/command.c.
1828 * Fixed a bug in private message receiving in the client library.
1829 The remote ID was freed and it wasn't supposed, now it is
1832 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1834 * Minor fix to the channel payload; allocate the data area, as it
1835 needs to be of specific length.
1837 * If the key agreement port is zero then the operating
1838 system will define the bound port. Affected files are
1839 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1841 * Added new function silc_channel_payload_decrypt into the file
1842 lib/silccore/silcchannel.[ch].
1844 * Moved the channel message etc, check from silc_packet_decrypt
1845 to applications. The library calls now a generic
1846 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1847 when the packet is either normal or special. This was done to
1848 allow more wide range of checking that was not allowed when
1849 the code was in library. Now applications can do virtually any
1850 checks to the packet and return to the library the decision how
1851 the packet should be processed. Affected files are
1852 lib/silccore/silcpacket.[ch].
1854 Added silc_server_packet_decrypt_check to the server and
1855 silc_client_packet_decrypt_check to the client library.
1857 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1858 to send with specified source and destination information.
1860 * Channel message delivery between routers was broken after the
1861 channel key distribution was fixed earlier. The channel key
1862 was used be to distributed to other routers as well which is not
1863 allowed by the protocol. Now this is fixed and channel keys
1864 really are cell specific and the channel message delivery between
1865 routers comply with the protocol specification.
1867 * Fixed various commands in server to check also the global list
1868 for the channel entry and not just the local list. The affected
1869 file silcd/command.c.
1871 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1873 * Added assert()s to buffer formatting and unformatting routines
1874 to assert (if --enable-debug) when error occurs. Affected
1875 file: lib/silcutil/silcbuffmt.c.
1877 * Changed to auto-reconnect to check whether the remote host is
1878 router and register the re-connect timeout if it is. It used
1879 to check that whether we are normal server, but router must do
1880 auto-reconnect with another router as well. Affected file
1883 * Removed the [<key len>] option from CMODE command as the cipher
1884 name decides the key length, nowadays. See the defined ciphers
1885 from the protocol specification.
1887 * Added [<hmac>] option to the CMODE command to define the HMAC
1888 for the channel. Added SILC_CMODE_HMAC channel mode.
1890 * Added [<hmac>] option for the JOIN command so that user can
1891 select which HMAC is used to compute the MACs of the channel
1894 * Added Hmac field to the Channel Message Payload. The integrity
1895 of plaintext channel messages are now protected by computing
1896 MAC of the message and attaching the MAC to the payload. The
1897 MAC is encrypted. Now, it is clear that this causes some
1898 overhead to the size of the packet but rationale for this is that
1899 now the receiver can verify whether the channel message decrypted
1900 correctly and also when private keys are set for the channel the
1901 receiver can decrypt the packet with several keys and check from
1902 the MAC which key decrypted the message correctly.
1904 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1905 lib/silccrypt/silccipher.[ch].
1907 * Added silc_hash_len to return the digest length into the
1908 lib/silcrypt/silchash.[ch].
1910 * Rewrote parts of Silc Channel Payload interface in the
1911 lib/silccore/silcchannel.[ch]. The encode function now also
1912 encrypts the packet and parse function decrypts it.
1914 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Fixed a minor formatting bug in the SKE's key material processing.
1917 It actually might have processed the keys wrong way resulting
1920 * Redefined the mandatory HMAC algorithms and added new algorithms.
1921 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1922 and hmac-md5 truncated to 96 bits. The mandatory is now
1923 hmac-sha1-96. Rest are optional (including the one that used
1924 to be mandatory). Rationale for this is that the truncated HMAC
1925 length is sufficient from security point of view and can actually
1926 make the attack against the HMAC harder. Also, the truncated
1927 HMAC causes less overhead to the packets. See the RFC2104 for
1930 * Added new [hmac] configuration section. The SKE used to use
1931 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1932 is of course wrong. The official names that must be proposed in
1933 the SKE are the ones defined in the protocol specification
1934 (hmac-sha1-96 for example). The user can configure any hmac
1935 using any hash function configured in the [hash] section. At
1936 least, the mandatory must be configured.
1938 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1940 * Added HMAC list to the SKE proposal list. It has now both
1941 hash algorithm list and HMAC list. This makes the protocol
1942 incompatible with previous versions. The SKE now seems to work
1943 the way it is supposed to work, for the first time actually.
1945 * Defined plain Hash algorithms to the protocol specification.
1948 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Implemented support for key agreement packets into the server.
1951 Added functions silc_server_key_agreement and
1952 silc_server_send_key_agreement. Other than these functions,
1953 server has nothing to do with this packet.
1955 * Added support for private message key packets into the server.
1956 Added functions silc_server_private_message_key and
1957 silc_server_send_private_message_key.
1961 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1962 called in the protocol's final callback instead in the END
1963 protocol state. This makes a little more sense and in the same
1964 time in client we can use the same protocol routines for normal
1965 key exchange and to key agreement packet handling as well.
1967 * Added to both client's and server's KE protocol context the
1968 SilcSKEKeyMaterial pointer to save the key material. We will
1969 bring the key material to the protocol's final callback by doing
1970 this. The final callback must free the key material.
1972 * Added SKE's packet_send callback into client's KE protocol
1973 context so that the caller can choose what packet sending function
1974 is used. This way we can use different packet sending when
1975 doing normal SKE when doing key agreement packet handling (in
1976 the key agreement packet handling we do not want to encrypt
1979 * Implemented the responder side of the key agreement routines
1980 in the client. The client can now bind to specified port and
1981 accept incoming key negotiation. The key material is passed
1982 to the application after the protocol is over.
1984 * Implemented the processing of incoming Key Agreement packet
1985 in the client. Added function silc_client_key_agreement to
1988 * Implemented the intiator side of the key agreement routines
1989 in the client. The client can now initiate key agreement with
1990 another remote client. The key material is passed to the
1991 application after the protocol is over.
1993 * Created client_keyagr.c to include all the key agreement
1996 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1997 SILC_TASK_CALLBACK except that it is not static.
1999 * Created client_notify.c and moved the Notify packet handling
2000 from the client.[ch] into that file.
2002 * Created client_prvmsg.c and moved all private message and
2003 private message key routines from the client.[ch] into that file.
2005 * Create client_channel.c and moved all channel message and
2006 channel private key routines from the client.[ch] into that file.
2008 * Changed silc_client_get_client_by_id_resolve to resolve with
2009 WHOIS command instead of IDENTIFY command, in the file
2010 lib/silclient/idlist.c.
2012 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2014 * Implemented the SKE's responder side to the Client library.
2016 * When FAILURE is received to the protocol do not trust it
2017 blindly. Register a timeout to wait whether the remote closes
2018 the connection as it should do it, only after that process the
2019 actual failure. This was changed to both client and server.
2021 * Added client_internal.h to include some of the structures
2022 there instead of client.h in lib/silcclient/.
2024 * Added function silc_task_unregister_by_callback to unregister
2025 timeouts by the callback function.
2027 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2029 * Some "Incomplete WHOIS info" errors has been appearing on the
2030 log files. Took away the entry->userinfo check from WHOIS
2031 reply sending. The entry->userinfo is now " " if client did not
2032 provide one. I thought this was fixed earlier but something
2033 is wrong still. Let's see if the error still appears.
2035 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2037 * Fixed a minor bug in the login when the channel key is
2038 re-generated in the server. It used to generate the key in
2039 wrong order and thus caused problems in the channel traffic.
2041 * Fixed a minor bug in channel key distsribution after
2042 KICK command. The key was not sent to the router even though
2045 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2047 * Added silc_ske_process_key_material_data as generic routine
2048 to process any key material as the SILC protocol dictates. The
2049 function is used by the actual SKE library but can be used by
2050 applications as well. This relates to the private message keys
2051 and the channel private keys since they must be processed the
2052 same way the normal SILC session keys. The protocol dictates
2053 this. Affected files: lib/silcske/silcske.[ch].
2055 Added also silc_ske_free_key_material to free the
2056 SilcSKEKeyMaterial structure.
2058 * Defined silc_cipher_set_key function to set the key for
2059 cipher without using the object's method function. The affected
2060 files: lib/silccrypt/silccipher.[ch].
2062 * Implemented silc silc_client_add_private_message_key,
2063 silc_client_add_private_message_key_ske,
2064 silc_client_del_private_message_key,
2065 silc_client_list_private_message_keys and
2066 silc_client_free_private_message_keys functions in the
2069 Added functions silc_client_send_private_message_key to send
2070 the Private Message Key payload and silc_client_private_message_key
2071 to handle incoming Private Message Key payload.
2073 * Added Cipher field to the Private Message Key payload to set
2074 the cipher to be used. If ignored, the default cipher defined
2075 in the SILC protocol (aes-256-cbc) is used.
2077 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Removed lib/silcclient/ops.h file.
2081 Redefined parts of the SILC Client Library API. Created new
2082 file silcapi.h that deprecates the ops.h file and defines the
2083 published Client Library API. Defined also private message key
2084 API and channel private key API into the file.
2086 This is the file that the application must include from the
2087 SILC Client Library. Other files need not be included by
2088 the application anymore.
2090 * Added new key_agreement client operation callback and also
2091 defined the Key Agreement library API for the application.
2093 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2095 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2096 is used by clients to request key negotiation between another
2097 client in the SILC network. If the negotiation is started it
2098 is performed using the SKE protocol. The result of the
2099 negotiation, the secret key material, can be used for example
2100 as private message key.
2102 Implemented the Key Agreement payload into the files
2103 lib/silccore/silauth.[ch].
2105 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Redefined ciphers for the SILC protocol. Added some new ciphers
2108 and defined the key lengths for the algorithms. Changed the
2109 code accordingly. The default key length is now 256 bits.
2111 * Fixed SKE key distribution function silc_ske_process_key_material
2112 when the key length is more than 128 bits. The default key
2113 length in SILC is now 256 bits.
2115 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2116 to indicate unsupported algorithm.
2118 * Renamed rijndael.c to aes.c and all functions as well.
2120 * Fixed a long standing channel key setting bug in client library.
2121 Weird that it has never surfaced before.
2123 * Fixed bug in channel deletion. If the entire channel is removed
2124 then it must also delete the references of the channel entry
2125 from the client's channel list as the client's channel entry and
2126 the channel's client entry share same memory.
2128 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2130 * Implemented CONNECT and SHUTDOWN commands in the client.
2132 * Implemented CLOSE command to the client.
2134 * Added the function silc_idlist_find_server_by_name into the
2135 files silcd/idlist.[ch].
2137 Added the function silc_idlist_find_server_by_conn into the
2138 files silcd/idlist.[ch].
2140 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2142 * DIE command was renamed to SHUTDOWN. Updated the both code
2145 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2146 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2148 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2151 * Added function silc_server_create_connection function to create
2152 connection to remote router. My server implementation actually
2153 does not allow router to connect to normal server (it expects
2154 that normal server always initiates the connection to the router)
2155 so the CONNECT command is only good for connecting to another
2158 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2160 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2161 or some other client was kicked from the channel.
2163 Implemented the handling of the notify type to both client
2166 Implemented silc_server_send_notify_kicked to send the KICKED
2167 notify. It is used to send it to the server's primary router.
2169 * Implemented the KICK command into server and client.
2171 * Added `query' argument to the silc_idlist_get_client function
2172 to indicate whether to query the client from server or not if
2175 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2176 to indicate that the client is not channel founder.
2180 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2182 * Removed the rng context from SilcPacketContext structure and
2183 changed that the packet routine uses the Global RNG API.
2185 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2187 * Added support for quit message that client can "leave" on the
2188 channel when it quits the SILC. It is ditributed inside the
2189 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2191 Added silc_server_free_client_data that will take the
2192 signoff message as argument.
2194 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2196 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2198 * Updated parts of the protocol specification to keep it up
2201 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2203 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2204 payloads in one packet.
2206 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2207 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2208 use now the new List flag.
2210 * Also deprecated the following packet types: REPLACE_ID,
2211 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2213 * Added list support for Notify packet in server.
2215 * Added silc_server_send_notify_channel_change to send the
2216 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2217 the silc_server_send_replace_id.
2219 * Added silc_server_send_notify_nick_change to send the
2220 NICK_CHANGE notify type. Deprecates the function
2221 silc_server_send_replace_id.
2223 * Added silc_server_send_notify_join to send the JOIN notify type.
2224 Deprecates the function silc_server_send_new_channel_user.
2226 * Added silc_server_send_notify_leave to send LEAVE notify type.
2227 Deprecates the function silc_server_send_remove_channel_user.
2229 * Added silc_server_send_notify_cmode and
2230 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2231 types. Deprecates the silc_server_send_set_mode function.
2233 * Added SERVER_SIGNOFF notify type to indicate that server has
2234 quit. This means that all clients on the channel from that
2235 server will drop. This can be also used when netsplit happens.
2237 Deprecated REMOVE_ID packet type since it is not needed anymore
2240 Added silc_server_send_notify_server_signoff to send the
2241 SERVER_SIGNOFF notify type. Deprecates the function
2242 silc_server_send_remove_id.
2244 Added also silc_server_send_notify_signoff to send the
2245 SIGNOFF notify type.
2247 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2248 SILC protocol from this day on. Changed the protocol
2249 specification as well.
2251 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2252 notify type. It is used between routers to notify about
2253 topic changes on a channel.
2255 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2258 * Partly updated the protocol specification to comply with the
2259 changes now made. It is still though a bit outdated.
2261 * The JOIN notify type now takes one extra argument <Channel ID>.
2262 The packet used to be destined to the channel but now the
2263 JOIN type may be sent as list thus it is impossible to
2264 destine it to any specific channel. By adding this argument
2265 it is again possible.
2267 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2269 * Added CREDITS file. The CHANGES and CREDITS file will appear
2270 in the distribution as well.
2272 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2274 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2275 types in the server's silcd/packet_receive.c.
2277 * Implemented CMODE and CUMODE to work in router environment.
2279 * Fixed minor encoding and decoding buglet from the
2280 lib/silccore/silcmode.c.
2282 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2285 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2287 * Changed all SilcConfigServer* and silc_config_server* to
2288 SilcServerConfig* and silc_server_config*, respectively.
2291 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2293 * Associated the ID (client or server ID) to the Authentication
2294 Payload to avoid any possibility of forging. Updated the
2295 protocol specification and the code accordingly.
2297 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * The RSA key length is now save to the RsaKey context in the
2300 key generation process in lib/silccrypt/rsa.c. The key length
2301 is now used to figure out the maximum size of the block allowed
2302 to be encrypted/signed.
2304 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2305 is equivalent to the silc_mp_mp2bin but does not allocate any
2308 * Changed silc_mp_mp2bin API to take length argument. If it is
2309 non-zero then the buffer is allocated that large. If zero, then
2310 the size is approximated using silc_mp_sizeinbase, which however
2313 * Created Global RNG API which is global RNG that application can
2314 initialize. After initializing, any routine anywhere in the
2315 code (including library) can use RNG without allocating a new
2316 RNG object. This was done to allow this sort of use of the
2317 RNG in code that has no chance to allocate RNG object. All
2318 applications currently allocate this and many routines in the
2319 library use this. Affected file lib/silccrypt/silcrng.[ch].
2321 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2322 it to use the Global RNG API.
2324 * Defined Authentication Payload into protocol specification that
2325 is used during SILC session to authenticate entities. It is
2326 used for example by client to authenticate itself to the server
2327 to obtain server operator privileges.
2329 Implemented this payload into the lib/silccore/silcauth.[ch].
2330 Implemented also routines for public key based authentication
2331 as the new protocol specification dictates.
2333 Moved definitions of different authentication methods from
2334 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2336 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2337 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2338 silc_pkcs_verify_with_hash functions into the file
2339 lib/silccrypt/silcpkcs.[ch].
2341 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2343 * The client entry's userinfo pointer must be always valid.
2344 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2345 will fail since it requires the userinfo. Now, the userinfo
2346 is allocated as "" if actual userinfo does not exist. Actually,
2347 it must exist and it is totally Ok to drop client connections
2348 that does not announce the userinfo. However, we will make
2349 this workaround for now.
2351 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2352 to return the remote port by socket.
2354 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2356 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2357 SILC_SERVER_PENDING_EXEC and added an new macro
2358 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2359 data or when error occurs while processing the pending command.
2361 Added new argument `destructor' into silc_server_command_pending
2362 and to the SilcServerCommandPending object. This destructor is
2363 now called after calling the pending callback or if error occurs
2364 immediately. If error occurs the actual pending callback won't
2365 be called at all - only the destructor. The destructor may be
2366 NULL if destructor is not needed.
2368 All this applies for client library code as well. Similar
2369 changes were made there as well for the pending commands.
2371 In the client, the application must now allocate the
2372 SilcClientCommandContext with the silc_client_command_alloc
2375 * Added reference counter to the SilcServerCommandContext. Added
2376 function silc_server_command_alloc and silc_server_command_dup
2379 Same type of functions added to the client library for the same
2382 * Removed the cmd_ident from IDListData away since it is now
2383 global for all connections. It is the command identifier used
2384 in command sending and with pending commands. The affected file
2387 * Added reference counter to the SilcSocketConnection objecet to
2388 indicate the usage count of the object. The object won't be
2389 freed untill the reference counter hits zero. Currently only
2390 server uses this, and client ignores it. The client must be
2391 set to use this too later. The affected files are
2392 lib/silccore/silcsockconn.[ch]. Added also the function
2393 silc_socket_dup to increase the reference counter.
2395 This was mainly added because it is possible that the socket
2396 is removed underneath of pending command or other async
2397 operation. Now it won't be free'd and proper DISCONNECTING
2398 flags, etc. can be set to avoid sending data to connection that
2399 is not valid anymore.
2401 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2402 the connection. After that it sets SILC_SET_DISCONNECTED.
2403 It is, however, possible that the socket data is not still freed.
2404 The silc_server_packet_process now checks that data is not
2405 read or written to connection that is DISCONNECTED. The socket
2406 get's freed when the reference counter hits zero.
2408 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2410 * Changed the client operation API: channel_message operation's
2411 `sender' is now the client entry of the sender, not the nickname
2412 and the `channel' is the channel entry, not the channel name.
2414 In the private_message operation the `sender' is now also the
2415 client entry of the sender not the nickname.
2417 Affected file is lib/silcclient/ops.h and all applications
2418 using the client operations.
2420 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2422 * Moved the calling of ops->connect() from connect_to_server_final
2423 into receive_new_id functin since that is the point when the
2424 client is actually allowed to send traffic to network. The
2425 affected file is lib/silcclient/client.c.
2427 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2429 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2430 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2431 (if needs broadcasting) instead of broadcasting the packets one
2432 by one which would make a burst in the network traffic.
2434 * Added `broadcast' argument to the functions in silcd/server.[ch]
2435 silc_server_create_new_channel[_with_id] to indicate whether
2436 to send New Channel packet to primary router.
2438 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2440 * Added new function into the silcd/server.[ch] files:
2441 silc_server_create_new_channel_with_id to create new channel with
2442 already existing Channel ID.
2444 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2445 lib/silccore/silcpacket.h. This packet is used t send list of
2446 Set Mode payloads inside one packet. Server uses this to set
2447 the modes for the channels and clients on those channels, that it
2448 announced to the router when it connected to it. The protocol
2449 specification has been updated accordingly.
2451 * The silc_server_new_channel did not handle the packet coming
2452 from normal server as it normally does not send that. However,
2453 when it announces its channels it does send it. Implemented
2454 the support for that.
2456 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2457 into the file lib/silccore/id.h.
2459 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2461 * Fixed memory leaks in the functions silc_idlist_del_client,
2462 silc_idlist_del_channel and silc_idlist_del_server in the file
2463 silcd/idlist.c. All of those leaked like a sieve.
2465 * Fixed some small memory leaks in the client's function
2466 silc_client_notify_by_server.
2468 * Added functions into silcd/server.c: silc_server_announce_clients,
2469 silc_server_announce_channels and silc_server_announce_server.
2470 These functions are used by normal and router server to announce
2471 to its primary router about clients, channels and servers (when
2472 router) that we own. This is done after we've connected to the
2475 These functions effectively implements the following packet types:
2476 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2477 and SILC_PACKET_NEW_ID_LIST.
2479 * Added new functions into the silcd/packet_receive.[ch]:
2480 silc_server_new_id_list, silc_server_new_channel_list and
2481 silc_server_new_channel_user_list to handle the incoming
2482 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2484 * Added support of changing Channel ID in the function
2485 silc_server_replace_id. If the server that announces a channel
2486 to the router already exists in the router (with same name but
2487 with different Channel ID), router is responsible to send
2488 Replace ID packet to the server and force the server to change
2489 the Channel ID to the one router has.
2491 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2492 client that the Channel ID has been changed by the router. The
2493 normal server sends this to the client. Client must start using
2494 the new Channel ID as the channel's ID.
2496 Implemented handling of this new type into lib/silcclient/client.c
2497 into the function silc_client_notify_by_server.
2499 * Added new function silc_idlist_replace_channel_id into the files
2500 silcd/idlist.[ch] to replace the Channel ID.
2502 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2504 * Call silc_server_command_identify_check always when processing
2505 the IDENTIFY command in silcd/command.c
2507 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2509 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2510 send keepalive packets. The packet can be sent by clients,
2511 servers and routers.
2513 Added function silc_socket_set_heartbeat into the file
2514 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2515 If not set, the heartbeat is not performed. The actual
2516 heartbeat is implemented in the low level socket connection
2517 library. However, application is responsible of actually
2520 Added silc_server_send_heartbeat to send the actual heartbeat
2521 packet into silcd/packet_send.[ch]. Server now performs
2522 keepalive with all connections.
2524 * Added silc_task_get_first function into lib/silcutil/silctask.c
2525 to return the timeout task with shortest timeout. There was a bug
2526 in task unregistration that caused problems. TODO has been
2527 updated to include that task system must be rewritten.
2529 * The client library will now resolve the client information when
2530 receiving JOIN notify from server for client that we know but
2531 have incomplete information.
2533 * Rewrote parts of silc_server_remove_from_channels and
2534 silc_server_remove_from_one_channel as they did not remove the
2535 channel in some circumstances even though they should've.
2537 * Encryption problem encountered in server:
2539 The LEAVE command used to send the Channel Key packet to the
2540 router immediately after generating it. However, the code
2541 had earlier sent Remove Channel user packet but not immediately,
2542 ie. it was put to queue. The order of packets in the router
2543 was that Channel Key packet was first and Remove Channel User
2544 packet was second, even though they were encrypted in the
2545 reverse order. For this reason, MAC check failed. Now, this
2546 is fixed by not sending the Channel Key packet immediately but
2547 putting it to queue. However, this is more fundamental problem:
2548 packets that are in queue should actually not be encrypted
2549 because packets that are sent immediately gets encrypted
2550 actually with wrong IV (and thus MAC check fails). So, packets
2551 that are in queue should be encrypted when they are sent to
2552 the wire and not when they put to the queue.
2554 However, the problem is that the current system has not been
2555 designed to work that way. Instead, the packet is encrypted
2556 as soon as possible and left to the queue. The queue is then
2557 just purged into wire. There won't be any fixes for this
2558 any time soon. So, the current semantic for packet sending
2561 o If you send packet to remote host and do not force the send
2562 (the packet will be in queue) then all subsequent packets to the
2563 same remote host must also be put to the queue. Only after the
2564 queue has been purged is it safe again to force the packet
2567 o If you send all packets immediately then it safe to send
2568 any of subsequent packets through the queue, however, after
2569 the first packet is put to queue then any subsequent packets
2570 must also be put to the queue.
2572 Follow these rules and everything works fine.
2574 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2576 * Added new function silc_server_remove_clients_by_server to
2577 remove all client entries from ID list when the server connection
2578 is lost. In this case it is also important to invalidate all
2579 client entires as they hold the invalid server entry. This
2580 fixes fatal bug when server has lost connection and will reconnect
2583 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2585 * Made some sanity checks to silc_server_daemonise like to check
2586 whether the requested user and group actually exists.
2588 * Added sanity check to SKE's silc_ske_responder_finish to check
2589 that the public and private key actually is valid.
2591 * Invalidate the client's nickname when receiving Replace ID
2592 packet and the Client ID is being replaced. This means that the
2593 server will query the nickname if someone needs it (client)
2596 * Sort the ID Cache in client library when the ID Cache data
2597 has changed (needs sorting).
2599 * Do not allow for SILC client to create several connections to
2600 several servers. The client does not support windows right now
2601 and generating multiple connections causes weird behaviour.
2603 Irssi-silc client does support windows and can handle several
2604 connections without problems, see: www.irssi.org and SILC plugin.
2606 * Fixed some places where client was added to the IDList. The
2607 rule of thumb is following (in order to get everything right):
2608 If the client is directly connected local client then the
2609 `connection' argument must be set and `router' argument must be
2610 NULL to silc_idlist_add_client function. If the client is not
2611 directly connected client then the `router' argument must
2612 bet set and the `connection' argument must be NULL to the
2613 silc_idlist_add_client function.
2615 * The funtion silc_server_packet_send_local_channel actually did
2616 not check whether the client was locally connected or not. It
2617 does that now. Fixed a bug related to LEAVE command.
2619 * Fixed Remove Channel User payload parsing bug in server's
2620 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2622 * The server's silc_server_save_channel_key now checks also the
2623 global ID list for the channel as it might not be in the local
2624 list. Fixed a bug related to LEAVE command.
2626 * Is this the end of the [<unknown>] buglet that has been lurking
2627 around for a long time? A little for loop fix in server's
2628 silc_server_command_whois_parse that is used by both IDENTIFY
2629 and WHOIS command. At least, this was a clear bug and a cause
2630 of one type of [<unknown>] buglet.
2632 * WHOIS and IDENTIFY commands call the function
2633 silc_server_command_[whois/identify]_check function even if
2634 we are not router server.
2636 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Added --with-gmp configuration option. If set the GMP
2639 is always compiled in the SILC source tree. If not set then
2640 it is checked whether the system has the GMP3 installed. If
2641 it has then the GMP won't be compiled (the system's headers
2642 and library is used), if it doesn't have it then the GMP is
2643 compiled in the SILC source tree.
2645 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2647 * Changed RSA private exponent generation to what PKCS #1
2648 suggests. We try to find the smallest possible d by doing
2649 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2650 not security fix but optimization.
2652 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2654 * Added new config entry [Identity] to fork the server and run
2655 it as specific user and group. A patch from Bostik.
2657 * Imported Dotconf configuration library into lib/dotconf.
2658 This will be used to create the SILC configuration files later.
2659 It will appear in the distsribution after this commit.
2661 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2663 * A big code auditing weekend happening. Auditing code for
2664 obvious mistakes, bugs and errors. Also, removing any code
2667 Removed files for being obsolete:
2669 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2670 inline in the file lib/silcutil/silcbuffer.h)
2672 o lib/silcutil/silcbufutil.c (the header has inline versions)
2674 Changed code to fix possible error conditions:
2676 o The buffer formatting routines now check that the destination
2677 buffer really has enough space to add the data. This applies for
2678 both buffer formatting and unformatting
2679 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2680 unformatting was changed to accomodate following rules:
2681 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2682 sent to the function while XXX_*STRING will not allocate or copy
2683 the data into the buffer. Instead it sets the pointer from the
2684 buffer into the pointer sent as argument (XXX_*STRING used to
2685 require that the pointer must be allocated already). This change
2686 makes this whole thing a bit more consistent and more optimized
2687 (note that the data returned in the unformatting with XXX_*STRING
2688 must not be freed now). The routines return now -1 on error.
2690 o Tried to find all code that use buffer_format and buffer_unformat
2691 and added return value checking to prevent formatting and
2692 especially unformatting errors and possible subsequent fatal
2695 o Changed ske->x and ske->KEY to mallocated pointers in
2696 lib/silcske/silcske.h. Fixed possible data and memory leak.
2698 o Added return value checking to all *_parse* functions. Fixed
2699 many memory leaks as well.
2701 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2702 so that buffer overflows would not happen. All code now also
2703 checks the return value as it can fail.
2705 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2707 * Added reconnection support to server if the normal server looses
2708 its connection to the router (for example if router is rebooted).
2709 The server performs normal reconnection strategy implemented
2710 to the server. Affected file silcd/server.c.
2712 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2714 * Added new packet type SILC_PACKET_SET_MODE that is used to
2715 distribute the information about changed modes (for clients,
2716 channels and clients channel modes) to all routers in the
2717 network. Updated the protocol specification accordingly.
2719 Added functions into silcd/packet_send.c and
2720 silcd/packet_receive.c: silc_server_send_set_mode,
2721 silc_server_set_mode.
2723 Added new files silcmode.[ch] into lib/silccore that implements
2724 the encoding and decoding of Set Mode Payload. Added new type
2725 SilcSetModePayload. Moved the definitions of different modes
2726 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2728 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2730 * Oops, a little mistake in server's connection authentication
2731 protocol. The protocol is not ended with FAILURE but with
2732 SUCCESS if the authentication is Ok. :) Affected file is
2735 * Implemented NICK_CHANGE notify handling in server in the file
2736 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2737 the local clients on the channel. After the changing nickname
2738 in router environment snhould work and the [<unknown>] nickname
2739 should appear no more.
2741 The silc_server_replace_id function that receives the Replace ID
2742 payload now sends the NICK_CHANGE notify type also in the file
2743 silcd/packet_receive.c
2745 * Changed WHOIS and IDENTIFY command to support the maximum amount
2746 of arguments defined in protocol specs (3328 arguments). This
2747 fixed a bug that caused problems when there were more than three
2750 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2752 * Added extra parameter, command identifier, to the
2753 silc_client_send_command so that explicit command identifier
2756 Changed that ID list routines uses specific command identifier
2757 when sending WHOIS/IDENTIFY requests to the server so that they
2758 can be identified when the reply comes back.
2760 Affected files lib/silcclient/command.[ch],
2761 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2763 * Added `sender' argument to silc_server_packet_send_to_channel
2764 to indicaet the sender who originally sent the packet to us
2765 that we are now re-sending. Ignored if NULL. Affected file
2766 silcd/packet_send.[ch].
2768 * Added some server statistics support in silcd/server_internal.h
2769 SilcServerStatistics structure and around the server code. Also
2770 send some nice statistics information when client is connecting
2773 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2775 * Fixed channel ID decoding in server's JOIN command reply in
2776 silcd/command_reply.c
2778 * Fixed braodcasting of replace ID payload to not to send it if
2779 we are standalone server in silcd/packet_receive.c.
2781 * Fixed all channel message sending routines to not to send
2782 packets to clients that has router set, since they are routed
2783 separately in the same function earlier. Affects file
2784 silcd/packet_send.c and all channel packet sending functions.
2786 * In USERS reply, res_argv[i] are not allocated, the table
2787 is allocated. Thus changed that free the table, not its
2790 * In server's whois_check and identify_check if the client is
2791 locally connected do not send any WHOIS commands - they are not
2794 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2796 * Fixed some minor bugs in client when sending WHOIS command. The
2797 arguments was in wrong order.
2799 * Removed statis function add_to_channel from server in
2800 silcd/command.c that was previously used with the joining but
2803 * Tested USERS command in router environment successfully with two
2804 routers, two servers and two clients.
2806 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2808 * Reorganized the USERS command and command reply in client library
2809 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2810 When the command is given by user we register a pending command
2811 callback that will reprocess the command after the reply has been
2812 received from the server. When reprocessing the packet we then
2813 display the information. Thus, the USERS information is displayed
2814 now in the command callback instead of in the command reply
2815 callback. The processing of the command is same as previously
2816 when server has sent the command reply in the JOINing process.
2818 * Added to USERS command in silcd/command_reply.c to join the client,
2819 we didn't use to know about, to the channel after we've created
2820 a client entry for it. Also, for clienet we did know already still
2821 check whether it is on the channel or not and add it if not.
2823 * Removed silc_server_command_join_notify as the function and its
2826 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2828 * Changed the client's pending command handling to the same as the
2829 server's pending command handling. It is also now possible to
2830 execute command reply functions from other command reply
2831 function as the function callbacks for commands and command
2832 replies are one and same. The pending commands are not static
2833 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2834 in client connection context. Thus, pending commands are server
2835 connection specific as it is convenient.
2837 Changed the function silc_client_command_pending and
2838 silc_client_command_pending_del and added new function
2839 silc_client_command_pending_check. Removed the
2840 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2843 * Added cmd_ident, current command identifier, to the client
2844 connection context in lib/silcclient/client.h to keep track on
2845 command identifiers used in command sending. Client's command reply
2846 function handling now supports the mandatory command identifiers.
2848 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2849 funtions in client to fully support pending command callbacks.
2851 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2852 as one of the arguments to the application in the command reply
2855 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2856 before first releasing SILC but came back. Now it is removed again
2857 and should come back nomore. The FORWARDED flag was used only
2858 by the JOINing procedure by forwarding the command packet to router.
2859 Now, the JOINing procedure has been changed to more generic (due
2860 to various router environment issues) and FORWARDED is not needed
2861 anymore for anything. The protocol specification is yet to be
2864 Now, removed silc_server_packet_forward from server and the flag
2865 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2867 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2869 * Renamed NAMES command to USERS command. The NAMES was named that
2870 due to historical reasons. Now it is renamed. Also, rewrote
2871 parts of the USERS command. The nickname list is not sent anymore
2872 by the server. Only Client ID and mode lists are sent in the USERS
2873 command. Changed this also to the protocol specification.
2875 The client now resolves the names and stuff after it receives
2876 the USERS list from the server when joining to the channel.
2878 * WHOIS and IDENTIFY commands has been changed to support multiple
2879 Client ID's per command. One can now search for multiple users
2880 in the network by sending only one WHOIS or IDENTIFY command.
2881 Changed the code and the protocol specifications.
2883 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2884 uses silc_server_command_whois_parse to parse the request. */
2886 * If normal server, do not parse the WHOIS and IDENTIFY requests
2887 before sending it to the router. Saves some time.
2889 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * Fixed JOIN command on client library. Wrong number of arguments
2892 used to crash the client.
2894 * Added silc_server_channel_has_global function to check whether
2895 channel has global users or not.
2897 * Added silc_server_channel_has_local function to check whether channel
2898 has locally connected clients on the channel.
2900 * The silc_server_remove_from_one_channel now checks whether the
2901 channel has global users or not after given client was removed from
2902 the channel. It also checks whether the channel has local clients
2903 on the channel anymore. If it does not have then the channel entry
2904 is removed as it is not needed anymore.
2906 * The silc_server_notify now checks on JOIN notify whether the joining
2907 client is one of locally connected or global. If it is global then
2908 the channel has now global users on the channel and that is marked
2909 to the channel entry. Also, it now saves the global client to
2910 global list who is joining and JOINs it to the channel. This is
2911 for normal server, that is.
2913 Changed silc_server_send_notify_on_channel,
2914 silc_server_packet_relay_to_channel and
2915 silc_server_packet_send_to_channel check if we are normal server
2916 and client has router set (ie. global client) do not send the
2917 message to that client, as it is already routed to our router.
2919 * Implemented LEAVE notify type handling in silc_server_notify
2922 * Tested LEAVE command in router environment successfully. Tested
2923 with two routers, two servers and two clients.
2927 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2929 * Implemented SIGNOFF notify type handling in silc_server_notify
2932 * silc_server_remove_id now removes the client entry from all channels
2933 it has joined and thusly sends SIGNOFF notify type.
2935 * Rewrote the NAMES list generation in server by removing two excess
2936 loops. The lists are created now inside one loop.
2938 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2940 * silc_server_remove_channel_user checks now also global list
2941 for channel and client.
2943 * silc_server_new_channel_user checks now both local and global
2944 list for channel and client. Fixed a bug in client id decoding.
2945 Used to decode wrong buffer.
2947 * silc_server_channel_message checks now both local and global
2948 list for channel entry.
2950 * Tested channel joining (hence JOIN) in router environment
2951 successfully. Tested with two routers, two servers and two
2954 * Tested channel message sending in router environment successfully.
2956 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2958 * Added silc_server_save_channel_key into server.[ch] to save the
2959 received channel key in Channel Key payload processing. It is
2960 also used in JOIN command reply handling.
2962 Equivalent function silc_client_save_channel_key added into
2963 client.[ch] into client library.
2965 * Changed JOIN command reply to send information whether the channel
2966 was created or not (is existing already) and the channel key
2967 payload. Changed protocol specs accordingly.
2969 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2970 the request was sent by ID and not by nickname. Crashed on
2973 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2976 now correctly save the received data.
2978 * silc_server_free_sock_user_data now notifies routers in the
2979 network about entities leaving the network.
2981 At the same time implemented functions silc_server_remove_id
2982 and silc_server_send_remove_id to receive and send REMOVE_ID
2983 packets. The packet is used to notify routers in the network
2984 about leaving entities. The ID removed will become invalid in
2987 * Added function silc_idlist_del_server into server. Removes and
2988 free's server entry from ID list.
2990 * silc_server_private_message function now checks, if we are router,
2991 that the destination ID really is valid ID, naturally.
2993 * In router when NEW_ID packet is received (for new client) the
2994 hash of the Client ID is saved in the ID Cache but the
2995 client->nickname is set to NULL, instead of putting the hash
2998 IDENTIFY command now also checks that client->nickname must be
2999 valid. If it is not if will request the data from the server who
3000 owns the client. Added new function
3001 silc_server_command_identify_check.
3003 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3004 to set the command to already allocated Command Payload.
3006 * Tested private message sending in router environment with two
3007 routers, two servers and two clients. Fixed minor bugs and now
3010 * Fixed segfault from client's NAMES command. Used to crash if
3013 * Forwarded packets must not be routed even if it is not destined
3014 to the receiver. Changed server code comply with this.
3016 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Added `require_reverse_mapping' boolean value to ServerParams
3019 structure. If TRUE (not default) the server will require that
3020 the connecting host has fully qualified domain name.
3022 If the reverse mapping is not required and hostname could not be
3023 found the IP address is used as hostname.
3025 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Implemented version string checking to both client and server.
3028 The check is incomplete currently due to the abnormal version
3029 strings used in development version of SILC.
3031 * Changed all command functions in server to use the new
3034 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Changed char *data to unsigned char *data in ID Cache system to
3037 support binary data as ID Cache data. Changed code to support
3038 binary data in lib/silccore/idcache.c.
3040 * Renamed silc_server_packet_relay_command_reply to
3041 silc_server_command_reply as it is normal packet receiving
3042 function. Rewrote the function to accept command replys for
3043 servers and not only for clients.
3045 * Mark remote router always as registered server if we are connecting
3046 to it. Otherwise, commands sent by the router to us are ignored.
3048 * All ID List find routines now returns the ID Cache Entry pointer
3049 as well if requested.
3051 * WHOIS command works now in router environment, tested with two
3052 routers, two servers and two clients.
3054 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3055 in router environment (as it is almost equivalent to WHOIS) but
3056 hasn't been tested thoroughly. Added new functions:
3058 silc_server_command_identify_parse
3059 silc_server_command_identify_send_reply
3060 silc_server_command_identify_from_client
3061 silc_server_command_identify_from_server
3063 * Disabled route cache adding because adding two different ID's with
3064 same IP replaces the old cache entry thus giving wrong route.
3065 The entry->router->connection is always the fastest route anyway
3066 so route cache may not be needed. Of course, new routes maybe
3067 established after receiving the ID when the entry->router->connection
3068 might not be anymore the most optimal.
3070 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3072 * Add route cache for received ID for fast routing.
3074 * Added silc_server_packet_route to route received packet on router
3075 that is not destined to us.
3077 * Renamed silc_server_get_route to silc_server_route_get.
3079 * Added id_string and id_string_len fields into SilcServer to
3080 include encoded ServerID for fast comparing without excess
3081 encoding of the ID's.
3083 * Cleaned up WHOIS command on server side. Added following static
3086 silc_server_command_whois_parse
3087 silc_server_command_whois_check
3088 silc_server_command_whois_send_reply
3089 silc_server_command_whois_from_client
3090 silc_server_command_whois_from_server
3092 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3093 arguments in command replies. All command functions should be
3094 updated to use this macro.
3096 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Minor typo fixes on command reply handling on server.
3100 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Added silc_server_command_add_to_channel internal routine to add
3103 the client to the channel after router has created the channel and
3104 sent command reply to the server.
3106 * Added generic silc_server_send_command to send any command from
3109 * Use static buffer with ID rendering instead of duplicating data.
3111 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Fixed a channel user mode bug when joining to a channel server gave
3114 everybody channel founder rights, oops.
3116 * We mark ourselves as the router of the incoming server connection
3117 if we are router ourselves. This way we can check in some packet
3118 sending functions whether it is locally connected server. For
3119 incoming router connections we put NULL.
3121 * For router sending packets locally means now always sending the
3122 packet cell wide; to local clients and local servers. For normal
3123 server sending packet locally means sending it to only local
3126 * Fixed the JOIN command to really work in router environment. If the
3127 channel is created it is always created by the router. Router is
3128 also responsible of making the initial joining to the channel,
3129 sending JOIN notify to the sending server and distributing
3130 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3131 does not exist server doesn't do anything else but forward the
3132 command to the router which performs everything.
3134 * Added silc_server_send_channel_key function to send the Channel Key
3137 * Added silc_server_create_channel_key to create new channel key. The
3138 channel key is now re-generated everytime someone joins or leaves
3139 a channel, as protocol dictates. Note: channel->key_len is the
3142 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3145 packet_receive.[ch] to separate packet sending and receiving
3146 routines. The server.[ch] now includes everything else including
3147 actual packet processing (writing and reading data) and other
3150 Renamed silc_server_private_message_send_internal to
3151 silc_server_send_private_message. The routine is still though
3152 used only to relay private messages as server does not send
3153 private messages itself.
3155 Renamed silc_server_new_channel to silc_server_create_new_channel
3156 and added new function sicl_server_new_channel that handles the
3157 incoming New Channel packet. Added also new sending function
3158 silc_server_send_new_channel to send New Channel Payload.
3160 * Added new function silc_server_notify to process incoming notify
3161 packet to the server/router. Server may then relay the notify
3162 to clients if needed.
3164 * Added new function silc_server_new_channel_user to process incoming
3165 New Channel User packet. Router will redistribute the packet and
3166 send JOIN notify to its local clients and locally connected servers
3167 if needed. Normal server will send JOIN notify to its local client
3168 on same channel when received this packet. Added also corresponding
3169 sending function silc_server_send_new_channel_user to sent the
3172 * Added boolean route argument to send_notif_to_channel and
3173 packet_send_to_channel functions to attempt to route the packet
3174 if it is TRUE and send only locally if it is FALSE.
3176 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3178 * silc_server_replace_id now broadcasts the received replace ID
3179 packet if it is not broadcast packet already. The router must
3180 broadcast to inform other routers about changed ID.
3182 * Added backpointer to server's router into SilcServer context in
3183 silcd/server_internal.h.
3185 * Fixed silc_server_packet_broadcast to send correct broadcast
3188 * The channel key is now distributed to the local client as soon
3189 as it is received from the router (in router environment) so that
3190 no other packet may be sent for the channel until client has
3193 * silc_server_remove_channel_user now broadcasts the received
3194 Remove Channel User packet if it is not broadcast packet already.
3195 The router must broadcast to inform other routers about removed
3198 * Added users field into SilcPacketContext that is a reference count
3199 of the context. One can increase the reference count by calling
3200 silc_packet_context_dup which is now changed to just increase the
3201 reference count instead of duplicating the data. The reference
3202 count is decresed by calling silc_packet_context_free that will
3203 free the data after the reference count hits zero.
3205 For now on the packet context and everything allocated into it
3206 (including the raw packet from network) must be freed by calling
3207 the new silc_packet_context_free function. Added also new function
3208 silc_packet_context_alloc that must be used now to allocate the
3209 context. This also means that if a routine is asynchronous from
3210 silc_[client/server]_packet_parse_type the packet context must
3211 be duplicated by calling silc_packet_context_dup. Otherwise it
3212 gets free'd after silc_[client/server]_packet_parse_type returns.
3213 Also, one must remember that if packet is duplicated then its
3214 reference count must be decresed by calling the free function as
3215 many times as it was duplicated.
3217 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3218 from both client and server.
3220 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3222 * Made joining to a channel working in router environment.
3224 * Cleaned up JOIN command on server side and create function
3225 silc_server_command_join_channel internal routine to make the
3228 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3230 * Changed silc_command_pending list to SilcDList. Also, added
3231 `ident' field to SilcServerCommandPending structure to identify
3232 the reply and to call correct callback.
3234 Added silc_server_command_pending_check function to replace the
3235 corresnponding macro. The silc_command_pending list is not
3238 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3239 to set identifier to previously allocated Command Payload. It
3240 is used to set identifier for command when resending Command
3243 * Added silc_command_payload_encode_payload to encode Command
3244 Payload buffer from SilcCommandPayload structure.
3246 * Added silc_argument_payload_encode_payload to encode Argument
3247 payload buffer from SilcArgumentPayload structure.
3249 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3251 * Changed WHOIS command to support router connection on server side.
3252 The whois request is always sent to router unless the server is
3253 standalone server. After server has received the reply from the
3254 router will it send the reply to the client.
3256 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3257 broadcast received broadcast packet. The function is used only
3258 by router. The broadcast packet is always sent to the router's
3261 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3262 render given ID to printable string, for log files for example.
3264 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3266 * Made basic router to router connections working. At least they
3267 can now connect to each other but nothing really works the way
3268 they are supposed - yet.
3270 * Added new initiator token to RouterConnection configuration
3271 file in silcd/serverconfig.[ch]. It is used to tell whether we
3272 are the initiator to the remote router or whether we'll expect
3273 the other end to connect.
3275 * Moved registering of listener task to silc_server_init, hence
3276 the server starts listenning as soon as it is run, even if it
3277 does not have connections to other routers. Let's see how well
3280 * Changed default connection retry timeouts for more suitable in
3283 * Removed cipher and such arguments from silc_idlist_add_client
3284 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3285 Added new function silc_idlist_add_data to add the keys and stuff
3288 * Added SilcIDListData structure and added it to SilcClientEntry
3289 and SilcServerEntry as their first field in the structure. This
3290 way we can explicitly cast the ID entries to the SilcIDListData
3291 structure and get common data for the entries. In past, we had
3292 to first check what type of connection it is and then cast it to
3293 correct ID entry type. Now, we can directly cast the opaque
3294 pointer to the SilcIDListData (no matter what ID entry it actually
3295 is) and get the data needed.
3297 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3300 in some circumstances even if threre were timeout tasks, though not
3301 IO tasks, but tasks anyway. Now fixed.
3303 * Defined SilcServerConnection structure to hold connection specific
3304 stuff about directly connected servers and routers. The definition
3305 is currently in silcd/server_internal.h. I thought about having
3306 a bit more important role fro this struct but for now it is used
3307 only when connecting to other server (or router actually).
3309 * Added connecting retry support in server when connecting to
3310 router(s). The retry feature implement exponential backoff
3311 algorithm. Also, added SilcServerParams structure to hold default
3312 parameters for server. For now, it include these retry settings
3313 and are hard coded. After server is moded to be as Silc Server
3314 Library this structure will be more important.
3316 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * Changed client librarys channel->clients table to SilcList and
3319 changed code accordingly.
3321 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * Changed client's channel table to SilcList and changed code
3324 accordingly. Also changed SilcChannelClientEntry to include back-
3325 pointer to the channel so that client entry can use that structure
3326 as list as well and we have fast cross-reference to the channel.
3327 This change dramatically decreased the complexity of channel
3328 handling with client entry and vice versa (removed one extra
3329 loop when searching for channel entry from many functions).
3331 * Changed server->sim from table to SilcDList and changed code
3334 * NAMES command can now be used from user interface. It will show
3335 the user list on the channel, neatly.
3337 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3338 Code now saves realname of the user if it becomes available.
3340 * Renamed configure.in to configure.in.pre and made ./prepare
3341 script to automatically add correct version string to
3342 configure.in which it creates from configure.in.pre.
3344 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3346 * NAMES command reply now shows users mode with the nickname when
3349 * Moved silc_client_ch[u]mode[_char] functions from
3350 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3351 place sucks, they are utility functions and should be in some
3354 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3356 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3359 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Added TRQ (efficient deque and list library) into lib/trq. This is
3364 a very good list library that is currently used in the SILC. Defined
3365 SilcList API over the library because I didn't like the API very
3366 much. See lib/trq/silclist.h for the API and examples of how to
3367 use the API. Fixed various places in the code to use the new
3368 SilcList API. The SilcList is meant for lists that has a structure
3369 already defined as a list. It is not suitable to add just some
3370 context to the list (in TRQ, the context is the list actually).
3372 So, I defined SilcDList that can be used for the purpose where
3373 predefined list structure does not exit. This can be used as
3374 such list. Now some context just can be added to the SilcDList.
3375 Currently this list is not used in the SILC just yet, though there
3376 are a lot places where this can replace dynamically allocated
3377 tables and I will fix these places, later, to use SilcDList.
3378 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3379 and use TRQ internally).
3381 Also fixed some annoying warning messages that the original TRQ
3382 code generated. Also minor changes to TRQ's Makefile.in.
3384 * Added support for querying by Client ID to both WHOIS and
3385 IDENTIFY commands into server, as required by the protocol.
3387 * Removed method function pointers from SilcBuffer structure. They
3388 weren't used to anything and just increased the context size for
3389 no good reason. This change also made silc_buffer_alloc and
3390 silc_buffer_free functions inline functions.
3392 * Disabled command flooding detection support until it's fixed so
3393 that it accepts commands in but does not execute them more than once
3396 * Added silc_net_localhost(), to return local hostname, into
3397 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3398 that must be initialized before calling silc_client_init.
3400 * Added new function: silc_server_send_notify_on_channels to send
3401 notify messages to all channels client has joined. It is assured
3402 that the message is sent only once per client.
3404 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3405 lib/silcutil/silcutil.[ch] as silc_format function. The new
3406 function is generic and is used by server as well, not only by
3407 the logging routines.
3409 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3410 the provided version string was not acceptable. Added new function:
3411 silc_ske_check_version into lib/silcske/silcske.h. The function
3412 must be implemented by the application (client or server) and it
3413 does not reside in the SKE library. The function checks the version
3414 string remote end sent.
3416 * Added back pointers (to opaque context and to SilcSocketConnection)
3417 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3419 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3420 duplicate packet context structure.
3422 * Changed `notify' client operation to send same arguments as client
3423 receives from server except for ID's. ID's are mapped to correct
3424 ID entry and that is returned. Also, if channel entry is not sent
3425 by server but the notify is for channel the channel entry is sent
3426 to application (otherwise application doesn't know that it is for
3427 channel (library gets it from packet's Destination ID)).
3429 * Added silc_client_remove_from_channels into client library to
3430 remove a client from all channels it has joined to. Used when
3431 received SIGNOFF notify from server. Added also new function
3432 silc_client_replace_from_channels to replace old ID entry with
3433 new ID entry on all channels. Used when received NICK_CHANGE
3436 * Fixed ID Cache list handling in silc_idlist_get_client in
3437 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3438 to get (or query) client by ID.
3440 * Updated TODO list.
3442 * Added connection authentication status message defined by the
3443 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3444 support for these into the code in client and server side.
3446 * Added generic function silc_client_send_command to send any command
3447 with variable argument list. Application should use this function
3448 to send commands if the command functions provided by the library
3449 does not suite for the application's user interface needs.
3451 * Added new `failure' client operation. Application is notified about
3452 received failure packet if client is executing a protocol. In this
3453 case the protocol's execution has failed.
3455 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3456 is required by the protocol.
3458 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3459 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3462 * Added status flag to SilcSKE object to indicate realtime status
3463 of the SKE protocol.
3465 * Application receives now exactly same command reply arguments as
3466 the library receives from server. However, if ID is received the
3467 corresponding ID entry is returned to the application (eg. Client
3468 ID is mapped to correct SilcClientEntry entry and that is returned).
3469 Changed command_reply client operation due to this change.
3471 * Changed all ID's in commands and in command replys as ID Payloads.
3472 Change affected both client and server side codes.
3474 All ID's sent in SILC network (with execption of ID's in SILC
3475 Packet header) are sent in ID Payload to support variable length
3478 * Server now notifies nick changes and notifies all clients on
3479 the channels about the new nickname (about the new Client ID,
3482 * Implemented CMODE command to change channel modes. Supports all
3483 channel modes defined by the protocol specs except ban and invite
3484 lists. (Also, private channel key mode is supported but support for
3485 setting private channel key in client is missing, thus, this mode
3486 has no effect on client side (except that server requires that the
3487 client uses private channel key and normal channel traffic does not
3490 Also, invite mode works per se, but INVITE command does not work
3491 yet correctly, so you can set channel as invite only channel but
3492 inviting clients to the channel does not work (it is yet to be
3493 thought what's the best way to do it).
3495 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3496 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3497 Implemented CUMODE command to change user's mode on the channel.
3498 Supports all modes defined by the protocol specs.
3500 * Added NAMES command reply to return users modes on the channel.
3502 * Removed unnecessary and slow ciphers from lib/silccrypt.
3504 * Set SO_KEEPALIVE option to connection sockets by default.
3506 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3508 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3509 redefined the Notify Payload into protocol specs.
3511 * Added silc_id_payload_parse_id to get ID directly from raw
3514 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3516 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3517 accept searching by Client ID as well.
3519 * Added support for LEAVE and SIGNOFF notify types in client library.
3521 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3522 to parse ID Payload from raw data.
3524 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Added flags parameter into silc_ske_assemble_security_properties
3527 function in lib/silcske/silcske.[ch].
3529 * Changed notify client operation to fit better for notify messages
3530 sent by server. The notify payload received from server is now
3531 passed to the application (after parsing it to SilcNotifyPayload).
3532 It is application's responsibility to retrieve the arguments
3533 from the payload and show the message the way it wants. The message
3534 sent by server is implementation specific.
3536 * Changed public keys to comply with the protocol specification.
3537 Old public keys are not supported anymore and are not compatible.
3539 * Removed nickname from Channel Payload as the latest draft removed
3540 it. The client must resolve the nickname from the NAMES command
3541 reply received when it joined the channel.
3543 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3545 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Fixed some errors in protocol specification drafts.
3549 * Created lib/silccore/silcnotify.c to implement Notify Payload
3550 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3551 generic payloads described by protocol specifications. The file
3552 includes implementations for ID Payload and Argument Payload.
3554 * Changed Command Payload implementation to use the new Argument
3555 Payload. Changed command_xxxx_payload to command_payload_xxxx
3556 to comply with SILC coding conventions.
3558 * Added suppport for Argument Payload handling in Notify Payload
3559 implementation as protocol requires it. Added the new support
3560 into server and client lib as well.
3562 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Added support for multiple nicknames on same channel. [n] is
3565 added locally to the nickname if there are more than one same
3566 nicknames on the channel.
3568 * Server now sends all nicknames that matched WHOIS request.
3569 Client also shows the list received from server.
3571 * Added TOPIC command to client side. User can now set and show
3572 current topic on channel.
3574 * Added MOTD command to client and server. Also, server sends the
3575 motd when client connects to the server.
3577 * Changed version strings to comply ISO 8601.
3579 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3581 * Fixed protocol error handling in client library. It should now
3582 cope even if the SKE fails for some reason.
3584 * Made new protocol specification drafts for submitting to IETF.
3586 * Implemented TOPIC command to server in silcd/command.c.
3588 * Added two new notify types into lib/silccore/silcnotify.h:
3589 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3590 notify nickname change and topic setting/change on a channel.
3592 * API change of command_reply operation in client library. The
3593 application gets now the status type received from server as well.
3595 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3599 * Cras fixed and optimized the packet handling even further and
3600 it should work now. Minor change to the prototype of function
3601 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3603 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Added new function into lib/silcutil/silcschedule.[ch]:
3606 silc_schedule_with_fd to select() a specified fd. The function
3607 returns after timeout expires or data arrives or goes. The
3608 function is used by packet routines to wait that all data is
3609 received from network.
3611 * Fixed data reading from network in lib/silccore/silcpacket.c.
3612 The code now assures that all data is read from the fd and then
3613 continues packet processing. This was a bug fix since the code
3614 used to drop some data in some circumstances.
3616 * Added new function into lib/silcclient/client.[ch]:
3617 silc_client_start_key_exchange to start key exchange after
3618 connection has been established to server. The code internally
3619 now uses this funtion but its main purpose was to provide it
3620 for applications that perform their own connecting. After
3621 application has created a connection it merely calls this
3622 function to start the key exchange between client and server.
3623 The library takes care of everything else after that.
3625 Updated also lib/silcclient/README to explain the usage of
3628 * Do not send to application information that connection has
3629 been established. Application gets notified it by connect
3632 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Applied cras's patch to add silc_schedule_one function. The
3635 function runs scheduler once and returns.
3637 * Fixed the scheduler after cras messed it up. The timeout
3638 handling works now as it's supposed to work.
3640 * Added into lib/silccore/ silcnotify.h to include notify
3641 message types support. Changed silc_server_send_notify*
3642 functions, in server.[ch], to support those new notify types.
3643 Added the support for the notify types into client library,
3644 as well. Added new notify client operation into ops.h in
3647 * Changed silc_server_packet_send_to_channel to send normal
3648 packets instead of just channel message packets. The function
3649 is now used to send the notify packets to channels. It is not
3650 used to send channel message packets anymore, as server never
3653 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3654 va_arg()s as it seems to require it nowadays. I guess, if SILC
3655 is compiled with older va_arg() the new code should work anyway.
3657 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Splitted core library. Core library (lib/silccore) includes
3660 now only SILC protocol specific core (and common) components.
3661 Created new utility library (lib/silcutil) that includes more
3662 generic purpose stuff. The stuff for util library was taken
3663 from the old core library. This was minor and easy split.
3665 * Created SILC Client Library (lib/silcclient) that includes
3666 implementation of the SILC client without user interface. This
3667 was major move from silc/ directory. The code has been changed
3668 so that it is transparent towards the user interface. The
3669 silc/ directory includes now the same user interface as before
3670 and it uses the new client library. Read lib/silcclient/README.
3671 Basicly, the client library performs everything else related
3672 to SILC except user interface handling. Also, configuration
3673 files are considered to be part of user interface and library
3674 does not handle them.
3676 This change also changed a lot of structures, function naming etc.
3677 Most important change was that SilcClientWindow object was
3678 renamed to SilcClientConnection in the client library. Created
3679 also new file lib/silcclient/ops.h. Also added new files
3680 silc/local_command.[ch] and silc/client_ops.[ch].
3682 All these changes were made to make it easier for user interface
3683 designers to create what ever user interface for the SILC client
3686 It is also expected that the server will be moved to lib
3687 directory as well and SILC Server Library will be created;
3688 sometimes in the future.
3690 * Removed Local commands from lib/silccore/silccommand.h as
3691 they are application specific and new client library does not
3692 handle any of those anymore.
3694 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3695 old client implementation in silc/.
3697 * Added support for callback functions in SILC_LOG_* macros.
3698 Application can now set its own callbacks that will be called
3699 instead of using the default functions that will always print
3700 the debug messages to stderr (or stdout). Also, debugging can
3701 now be disabled by setting silc_debug to FALSE and re-enabled by
3702 setting it to TRUE. Note, that logging will still work even
3703 if debugging is disabled.
3705 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3706 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3707 silc_log_reset_debug_callbacks.
3709 * To enable debugging in silc client one must give now -d
3710 option on command line.
3712 * Changed silc_schedule_init to automatically allocate task queues
3713 if they are not allocated before calling it.
3715 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * Added GMP 3.1 into math library.
3719 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3721 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3722 a channel in SILC network. The packet is used by servers and
3723 routers to notify other routers that user has left a channel.
3724 This little feature was missing until now. Added the feature
3725 to protocol specification as well.
3727 Added functions: silc_server_send_remove_channel_user and
3728 silc_server_remove_channel_user into server.[ch].
3730 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3731 lib/silccore/silcpacket.h. However, they are not implemented
3734 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3736 * Fixed joining to a channel and sending channel messages
3737 between server and router. The channel message sending should
3738 now work inside a cell.
3740 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Fixed the private message sending between server and router.
3743 The private message sending should now work inside a cell.
3745 * Added silc_server_replace_id into server.[ch] to replace
3746 existing ID in the SILC network.
3748 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3749 and silc_idlist_replace_server_id into idlist.[ch] in server.
3751 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Fixed the server to server connections. Server can again now
3754 connect to router. Router to router connections probably does
3757 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3759 * Added dynamic protocol registering support. Now protocols can
3760 registered and unregistered on the fly. Patch by cras.
3762 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Added lib/contrib directory to hold routines that some platforms
3765 don't have but are needed by SILC.
3767 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3768 into lin/contrib to provide getopt() and getopt_long() for
3769 those who don't have it.
3771 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3773 * Added AWAY command to client. When away message is set and
3774 client receives a private message packet the client automatically
3775 replies to the sender with the away message.
3777 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3778 bug seemed to be the cause of recent problems when compiling
3781 * Added version detection support to SKE protocol specification
3782 and added the new changes to the SKE implementation as well.
3783 There were other minor changes in the SKE protocol as well.
3785 Many changes in lib/silcske/silcske.[ch] and in
3786 lib/silcske/payload.[ch].
3788 * Added ^U functionality, clear input line. Patch from cras.
3790 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Mainly small bugfixes on core library. Fixed some debugging
3793 logging and buffer overflow in silclog.c.
3795 * Updated config.sub and config.guess on the distribution tree.
3797 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Added command lagging support in server. Client may execute
3800 commands now only once in two seconds.
3802 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Optimized packet reception. MAC computation and checking is now
3805 also more optimized. A lot previously duplicated code is now
3806 used as generic by both client and server.
3808 * Fixed key pair generation in clientutil.c
3810 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Added into lib/silccore/silcbufutil.[ch] new function;
3813 silc_buffer_realloc.
3815 * Moved generic packet sending/encryption functions to
3816 lib/silccore/silcpacket.[ch] from client and server. Some
3817 rewriting of the functions.
3819 * Moved all generic packet reception/decryption functions to
3820 lib/silccore/silcpacket.[ch] from client and server. The
3821 packet processing is now much cleaner in both client and server.
3822 These were major changes in both client and server.
3824 * Created many common functions in server to do packet sending.
3825 Previously code were duplicated a lot, this has been removed
3828 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * Rewrote major parts of the ID cache system. Don't know
3831 whether it is better now or not but at least the API is more
3834 * Major rewrite on ID cache stuff on client because of the ID
3835 cache API changes. Added idlist.c to client.
3837 * Also major rewrite on ID cache stuff on server as well.
3838 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3839 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3840 in hand, instead they are all put into the ID cache system now.
3841 All server_idlist_* routines uses ID cache now instead of
3842 traversing its own lists (those lists does not exist anymore).
3843 SilcIDList though still exists. Also, SilcXXXEntry's are
3846 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3848 * Finally made the SKE implementation compliant to the protocol
3849 specification. All mp integers are now binary encoded as
3850 opposed being HEX encoded.
3852 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3855 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3856 functions: silc_[encode/decode]_pem. Also added function
3857 silc_encode_pem_file to PEM encode with newlines ('\n') for
3860 * SILC public keys are now encoded either PEM or binary. Same
3861 option is for private keys as well. By default private keys
3862 are binary encoded and public keys PEM encoded. Silly HEX
3863 encoding were removed.
3865 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3866 function to create fingerprints.
3868 * Fixed a bug in SHA1; does not change the original data anymore.
3870 * Partly implemented INFO command on client and server side.
3871 Fixed CLEAR command. Changes to SERVER command; show current
3872 server(s) when giving command without arguments. Added
3873 VERSION command to client.
3875 * Added check to server that unregistered connections cannot
3876 execute commands (unless it is specificly allowed).
3878 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Fixed screen refresh.
3882 * Fixed channel joining bug from client. On some circumstances
3883 client tried to join to a channel it had already joined.
3885 * Added public key verification process into client's protocol.c.
3886 The client now verifies the public key from user and saves
3887 it into ~./silc/serverkeys/ directory.
3889 Added into: clientutil.[ch]: silc_client_verify_server_key.
3891 * Changed SKE protocol's silc_ske_initiator_finish function
3892 to accept callback function that verifies the received public
3893 key. Removed old silc_ske_verify_public_key function.
3895 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3897 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3898 silc_pkcs_private_key[_data]_set.
3900 * Made the password and public authentication more cleaner in
3901 server's protocol.c.
3903 * Removed historic and obsolete protocol `channel_auth' from
3904 both client and server.
3906 * Removed wrong way of sending command status messages from
3907 server to client in server's command.c. The old way violated
3908 protocol specification.
3910 Changes to silccore/silccommand.[ch]: removed
3911 silc_command_encode_status_payload -> not needed anymore,
3912 changed silc_command_encode_payload_va to accept extra
3913 argument on variable argument list. The argument type must
3914 now be provided to the function. Also, added new function:
3915 silc_command_encode_reply_payload_va which is same as
3916 normal command_encode_payload_va except command status type
3917 is provided as extra argument.
3919 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Added ~./silc directory handling. The directory includes the
3922 public and private keys for the client.
3924 Added silc_client_check_silc_dir, silc_client_create_identifier
3925 and silc_client_load_keys.
3927 * Implemented SILC protocol compliant public key. Added public
3928 and private key saving to and loading from files.
3930 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3931 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3932 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3933 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3934 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3936 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3937 silc_pkcs_load_[public/private]_key.
3939 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3941 * Added silc_server_get_route (route.[ch]) to get connection
3942 data for the fastest route for given ID.
3944 * Implemented INVITE command on client and server. The command
3945 were re-defined in the SILC Protocol Specification and the
3946 implementation now complies with the specification.
3948 * Implemented PING command on client and server.
3950 * Implemented NAMES command on client and server. The server side
3951 supports currently only normal server not router server yet.
3952 Some changes to NAMES definition in SILC protocol specification.
3954 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Implemented LEAVE command on client and server.
3958 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3959 again. This change was made to the protocol as well. Server
3960 should not violate the protocol specification anymore.
3962 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3965 was tested. SOCKS4 was not but should work anyway.
