3 * Changed the protocol API a bit more consistent in the
4 lib/silccore/silcprotocol.[ch].
6 * Changed the following headers to ROBODoc format:
8 lib/silccore/silcpayload.h
9 lib/silccore/silcprotocol.h
10 lib/silccore/silcsockconn.h
12 All core library headers are now formatted.
14 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
16 * Fixed a bug in Irssi SILC client; do not show that you are
17 server/router operator if you really are not. Affected file is
18 irssi/src/silc/core/client_ops.c.
20 * Renamed silc_command_free_payload to silc_command_payload_free.
21 Affected file lib/silccore/silccommand.h
23 * Added silcmath.h to include the prototoypes of various routines
24 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
27 * Changed the following headers to ROBODoc format:
29 lib/silccore/silcchannel.h
30 lib/silccore/silccommand.h
32 lib/silccore/silcidcache.h
33 lib/silccore/silcmode.h
34 lib/silccore/silcnotify.h
35 lib/silccore/silcpacket.h
36 lib/silcmath/silcmath.h
38 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
40 * Added checking to the server code not to start the server if
41 ciphers and stuff are not configured properly. Affected files
42 silcd/serverconfig.[h] and silcd/server.c.
44 * Changed the layout of the header files of the public interfaces
45 in the SILC libraries. The new layout supports ROBODoc
46 documentation tool (and some others) so that it is easy to create
47 a library reference manual. All the other headers and source
48 code must still follow the CodingStyle document. Also source
49 code must not include these ROBODoc stuffs, only the headers.
50 Furthermore, all public interface headers must now be named
51 by using `silc' prefix, example: silcapi.h, silccipher.h.
52 Some files were renamed due to this. All the other headers
53 must not be used as public interfaces. I will update the
54 CodingStyle document later. Changed following headers, so far:
56 lib/silcclient/silcapi.h
57 lib/silccore/silcauth.h
58 lib/silccore/silcprivate.h
59 lib/silccrypt/silcdh.h
61 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
65 * Removed silc_client_packet_send_flush from the client library
66 as it is not needed. Affected file lib/silcclient/client.[ch].
68 * Added printing of message of unresolved authentication method
69 to the Irssi SILC client. Added it to the module formats.
70 Removed the same message from the client library.
72 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
74 * Added new distribution feature, DISTLABEL. Every distribution
75 can define own preprocessor label that can be used in the
76 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
77 file distributions, acconfig.h.pre and prepare.
79 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
81 * Added Makefile.defines_int to include the actual definitions
82 for Makefile.defines.in. Tested the new distribution system,
83 created distributions and tested installation.
85 * Added AWAY message printing to the Irssi SILC client. Added
86 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
88 * Added SCONNECT command to call the SILC's CONNECT command.
89 Cannot use CONNECT directly since Irssi uses that internally.
90 Affected file irssi/src/silc/core/silc-servers.c.
92 Added ACTION local command. It is same as ME command but takes
93 the channel as mandatory argument.
95 Rewrote some of the Irssi's help files to suite for SILC
98 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
100 * Added Makefile.defines[.in] that should for now on be included
101 in all Makefile.am file in the source tree. That file includes
102 all common compilation definitions for SILC source tree.
104 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
106 * Minor changes to the ./prepare script to change the package
107 name according the distribution name to the configure.in.
109 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Created new distribution system. Added file `distributions'
112 that defines all the distributions that can be created out of
113 the SILC source tree. The ./prepare script now reads that
114 file to determine how to prepare the distributions. The
115 first argument to the ./prepare is the name of the distribution
116 and second is the version of the distribution. If given
117 without arguments it creates the default (toolkit) distribution
118 with the default version (defined in ./prepare).
120 All Makefile.am files that are subject to the distributions
121 are now named as Makefile.am.pre. These are ./Makefile.am
122 and lib/Makefile.am. Others may be changed later.
124 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
126 * Added invite list, ban list, some key management and connection
127 error message printing to module formats in the Irssi SILC client.
129 * Added new silc_client_set_away_message to set the away message
130 that is back to the person who sent private message. The
131 affected file lib/silcclient/silcapi.h and the
132 lib/silcclient/client_prvmsg.c.
134 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
136 * Fixed the private message sending in the Irssi SILC client,
137 added local command KEY to the Irssi SILC client.
139 Added key management and key agreement message formats to the
140 irssi/src/fe-common/silc/module-formats.[ch].
142 Added USERS (alias WHO) printing, server/router operator
143 indication and LIST command printing to the module formats.
145 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
147 * Fixed channel joining notify handling, cumode notify handling
148 from Irssi SILC client.
150 * Added SILC specific module-formats to the Irssi SILC client so
151 that SILC specific message hilighting, colors etc is possible.
152 Affected file irssi/src/fe-common/silc/module-formats.[ch].
154 Added channel mode, channel user mode, actions, notices,
155 whois and whowas printing to the the module-formats.c.
157 * Fixed a bug in channel deletion in the server. The channel
158 is not left to the cache even if the channel founder auth mode
159 is set when there are no users anymore on the channel. Affected
162 * The silc_net_localhost now resolves the entire hostname including
163 the domain name. Affected file lib/silcutil/silcnet.c.
165 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
167 * Changed the ask_passphrase client operation to be ascynchronous.
168 It has now a completion callback and a context that the
169 application must call after it has got the passphrase from
170 the user. Affected files lib/silcclient/silcapi.h,
171 lib/silcclient/protocol.c, lib/silcclient/command.c and
174 Added SilcAskPassphrase callback that the application calls
175 to deliver the passphrase to the library.
177 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
178 The public key verification and especially a certificate
179 verification is asynchronous procedure.
181 Added new SILC_SKE_STATUS_PENDING status to indicate the
182 request is pending and a callback will be called to finalize
185 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
186 indicate that remote end did not send its public key (or
187 certificate), even though we require it. Added check for this
188 condition in the SKE. This was a security bug, now fixed.
190 Defined new SilcSKEVerifyCbCompletion callback that is called
191 when the verification process is completed.
193 The affected files lib/silcske/silcske_status.h and
194 lib/silcske/silcske.[ch].
196 * Changed the verify_public_key client operation to be async
197 as well. Defined SilcVerifyPublicKey callback that is used to
198 indicate the success of the public key verification process.
200 Changed the server and client to use the new async client
203 * Changed the Irssi SILC client's internal scheduler to be called
204 twice as many times as it used to be. As a result the client
205 should be a bit faster now. Affected file is
206 irssi/src/silc/core/silc-core.c.
208 * Added support to Irssi SILC client of asynchronous public key
209 verification and passphrase inquiry. Affected file is
210 irssi/src/silc/core/silc-core.c.
212 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
214 * Do not say "You have left channel %s" in client library.
215 Moved it to the application. Affected files are
216 lib/silcclient/command.c and silc/client_ops.c.
218 * Fixed silc_client_get_clients. Command context was not
219 duplicated and was freed memory in the callback. Affected
220 file lib/silcclient/idlist.c.
222 * Do not say "you are now talking..." on JOIN command in the
223 client library. The appliation must handle it.
225 * Do not say ".. changed topic to" in command reply in the
226 client libary. The application must handle it.
228 * Fixed TOPIC command sending in the client library.
230 * Fixed a memory leak in silc_client_command_free in the file
231 lib/silcclient/command.c.
233 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
235 * Imported a modified version of Irssi client to the source tree.
236 The Irssi will be used to create a new client called
237 Irssi SILC. Imported to irssi/.
239 Added silc_core_init_finish function to the Irssi. Affected
240 file irssi/configure.in.
242 A lot changes in the Makefile.ams around the irssi tree.
244 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
246 * Do not rehash if the new size is same as the old size of the
247 hash table, in the silc_hash_table_rehash*. The affected file
248 lib/silcutil/silchashtable.c.
250 * Replaced hash_table_del_by_context calls from the server
251 (when channel->user_list and client->channels) to the
252 hash_table_del as it is sufficient and faster.
254 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
256 * Added silc_hash_table_list, silc_hash_table_get and the
257 SilcHashTableList structure to provide an alternative way to
258 traverse the hash table. The affected files are
259 lib/silcutil/silchashtable.[ch].
261 * Changed the server's idlist routines to use the hash table
262 routines to optimize the code.
264 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
266 * Replaced the client entry's `channel' list and channel entry's
267 `user_list' list to hash tables for optimized lookup. Changed
268 the code to use the hash table interface around the code.
269 Affected file lib/silcd/idlist.[ch].
271 * Added `auto_rehash' boolean argument to the function
272 silc_hash_table_alloc to indicate whether the hash table should
273 auto-rehash when it thinks is appropriate time. It will
274 increase the hash table size if the there is twice as much
275 entries in the table than the size of the table, and will
276 decrease the size if there are twice as less entries than
277 the size of the table.
279 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
281 * Fixed silc_xxx_get_supported to not crash at some circumstances.
283 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
285 * silc_idcache_purge_by_context deletes the entry now by context
286 as it is supposed to do. Affected file lib/silccore/idcache.c.
288 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
289 client is not anymore valid (WHOWAS givens the info) and not
290 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
292 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
294 * Removed the `data' and `data_len' arguments from the ID Cache
295 interfaces and added `name' argument. ID Cache does not handle
296 anymore the binary data only a names associated with given ID.
298 * When hashing a Client ID with silc_hash_id the entire ID is
299 not hashed anymore, instead only the hash of the Client ID is
300 hashed. This way we can access the Client ID from the cache
301 with Client ID but with the hash of the ID (which is a hash of
302 the nickname) as well without any difference in performance.
304 Added also silc_idcache_find_by_id_one_ext to do one on one
305 searching when we have the actual ID. Added also function
306 silc_hash_client_id_compare. The affected files are
307 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
309 * When hashing the name associated with a ID it is always done
310 in lowercase. This way we can access the cache without worrying
311 about case-sensitivity, even though, for example nicknames are
314 * Fixed a bug in server with channel message sending. It put
315 wrong ID type as destination ID. The affected file
318 * silc_idcache_del_by_context now deletes from all hash tables
319 by context. Affected file lib/silccore/idcache.c.
321 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
323 * Changed the client library to use the new ID Cache interface.
324 Changes around the source tree.
326 * Added silc_hash_table_rehash_ext to rehash with specific
327 hash function. Affected file lib/silcutil/silchashtable.[ch].
329 * Added silc_hash_string_compare to compare two strings in the
330 hash table. Affected file lib/silcutil/silcutil.[ch].
332 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
334 * Added new function silc_idcache_del_by_context into the
335 lib/silccore/idcache.[ch].
337 * Changed the server's ID list routines to use the new ID Cache
338 interface. Changes around the source tree.
340 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
342 * Added silc_hash_table_del[_by_context]_ext functions in to the
343 lib/silcutil/silchashtable.[ch].
345 Removed silc_hash_table_find_all* routines and added new
346 silc_hash_table_find_foreach to replace them.
348 Added silc_hash_table_replace_ext function as extended
349 replacing function. Separated the simple hash table interface
350 from the extended hash table interface in the file
351 lib/silcutil/silchashtable.h.
353 * Fixed minor bugs and changed it to use some of the new
354 hash table functions in lib/silccore/idcache.c
356 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * Added new function silc_hash_table_find_all to return all keys
359 in the hash table by the specified key. As the hash table is
360 collision resistant it also makes it possible to have several
361 duplicate keys in the hash table. This function may be used to
362 find all of the keys from the hash.
364 Added user_context arguments to the SilcHashFunction,
365 SilcHashCompare and SilcHashDestructor to deliver user specified
368 Added new fuctions silc_hash_table_find[_all]_ext to do
369 extended lookup with specified hash and compare functions and
370 specified user contexts.
372 Added new function silc_hash_table_add_ext to add the key
373 with specified hash function and user context.
375 Added new function silc_hash_table_foreach to traverse all
376 entrys in the hash table. Added SilcHashForeach callback
379 Added new function silc_hash_table_del_by_context to delete
380 the entry only if the context associated with the key matches.
382 Affected files are lib/silcutil/silchashtable.[ch].
384 * Removed silc_hash_[server/client/channel]_id and added just
385 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
386 silc_hash_id_compare to compare two ID's using as the hash table
387 comparison function. Added also silc_hash_data to hash
388 binary data and silc_hash_data_compare to compare it.
390 * Removed silc_idlist_find_client_by_hash as it is not needed
391 anymore. Affected file silcd/idlist.[ch].
393 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
394 to use internally the SilcHashTable. The new ID Cache is a lot
395 faster than the old one. Some of the ID Cache interface was also
396 rewritten and obsolete and stupid functions were removed.
398 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
400 * Added entry_count field to the SilcHashTable to keep the number
401 of the entries in the table. Implemented the function
402 silc_hash_table_rehash. Added new function
403 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
405 Fixed a minor bug in silc_hash_table_free.
407 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
408 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
409 into the lib/silcutil/silcutil.[ch].
411 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
413 * Implemented a collision resistant hash table into the
414 lib/silcutil/silchashtable[ch]. See the header and the source
415 for the SilcHashTable API.
417 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
419 * Merged dotconf version 1.0.2 into lib/dotconf.
421 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
423 * Do not compile anything in lib/silcsim/* if the SIM support
424 is not enabled. The tree should now compile without problems
427 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
429 * Compiled the SILC under cygwin. Compiled and tested briefly
430 without problems. More tests needed. The SIMs didn't compile
433 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
435 * Fixed possible crash in silc_get_username in the
436 lib/silcutil/silcutil.c.
438 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
440 * Fixed a va_arg in silc/client_ops.c.
442 * Oops, RC5 routines were named AES and caused some problems
443 when not using SIM's. Affected file lib/silccrypt/rc5.c.
445 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
447 * Added new SilcIDIP structure into the lib/silccore/id.h and
448 replaced the old `ip' fields from all SILC ID's to that type.
449 This is a step towards IPv6 support.
451 The silc_id_get_len takes now the ID as an extra argument.
452 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
453 both IPv4 and IPv6 based ID's.
455 The affected files are lib/silccore/id.[ch] and other files
456 around the tree using these routines.
458 * Removed the ID length arguments in server from various
459 silc_server_send_notify_* routines -> they are not needed
462 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
464 * Fixed memory leak in silc_encode_pem_file in the file
465 lib/silcutil/silcutil.c.
467 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
469 * Check minor version as well in the SKE. Affected files are
470 silcd/protocol.c and lib/silcclient/protocol.c.
472 * Added --identifier option to the server so that an identifier
473 can be when creating the public key for the server. Affected
474 file is silcd/silcd.c.
476 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
477 lib/silccrypt/silcpkcs.c.
479 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Register default ciphers and stuff when using -C option with
482 the server. Affected file sildc/silcd.c.
484 * Put back the servers public key filename format, it is better
485 than the new one. For now, the client keys are saved with the
486 new filename format. The affected file silc/client_ops.c.
488 * Implemented the Cipher API for the rest of the ciphers that
489 did not implement it or implemented it the wrong way.
491 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Register default ciphers and stuff when using the -S option
494 in the client. Affected file silc/silc.c. Same also when
495 creating new key pair with -C option.
497 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
499 * Fixed the silc_verify_public_key client operation function to
500 save the public keys differently. The fingerprint is now
501 used as filename and not the hostname. This way also the
502 client keys are saved uniquely and not with hostnames. The
503 affected file is silc/client_ops.c.
505 * Trimmed the silc_hash_fingerprint function to remove extra
506 whitespaces from the end of the fingerprint. The affected
507 file is lib/silccrypt/silchash.c.
511 * Added silc_cipher_register_default function to register all
512 default ciphers. It can be used when configuration files
513 does not exist and the application does not want any specific
514 ciphers in any specific order.
516 The SilcDList is now used as silc_cipher_list dynamically
517 allocated cipher list. Removed the static list all together
518 and now all ciphers must be allocated to the dynamic list.
519 The silc_cipher_alloc routine was changed to check only the
522 All silc_cipher_* routines that used to return int returns
525 The affected files lib/silccrypt/silccrypt.[ch].
527 * The same thing was done to silc_hash_* as for silc_cipher_*
528 routines. Affected files lib/silccrypt/silchash.[ch].
530 * The same thing was done to silc_pkcs_* as for silc_cipher_*
531 routines. Affected files lib/silccrypt/silcpkcs.[ch].
532 Added also silc_pkcs_[un]register[_default] functions.
533 Removed the data_context from the PKCS API.
535 * Added silc_hmac_register_default function to register default
536 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
537 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
538 to unregister all hmacs at once.
540 * Register the default ciphers, hash functions, PKCSs and HMACs
541 if client's configuration file does not exist. The affected
544 * The client did not load the hash functions from the SIM
545 modules at all. Added support for this. Affected file is
548 * When decoding public key with silc_pkcs_public_key_decode, check
549 the supported algorithm only if PKCS are registered. Affected
550 file lib/silccrypt/silcpkcs.c. The same was done with the
551 silc_pkcs_private_key_decode.
553 * Fixed the SILC List routines to keep the list always in order.
554 It used to change the list's order when traversing the list but
555 not it preserves the order. Affected file lib/trq/silclist.h.
557 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Added the client library to use the SilcSocketConnection's
560 reference counter (by silc_socket_dup) to prevent the bug that
561 the socket object may be freed underneath async operation.
563 * The name resolv library checking fixes in the configure.in.pre.
566 * Created new version of the protocol drafts for future
567 development. The -03 drafts are the ones that will be changed
568 in the trunk now and the -02 will remain as they are.
570 * Send list of CUMODE notifys to the router when announcing
571 the channel users to the router. Affected file silcd/server.c.
572 If the router receiving channel founder CUMODE for a channel
573 that already has channel founder it will send CUMODE notify
574 to the sender to remove the channel founder rights from the
575 announced client. Affected file silcd/packet_receive.c.
577 * The CUMODE notify may now use Server ID as well as the entity
578 who changes the mode. Updated protocool specs.
580 * Updated INSTALL and README files.
582 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
584 * New web pages in the http://silc.pspt.fi. The pages was
589 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
591 * Implemented the [DenyConnectin] config section in the server.
592 Added silc_server_config_denied_conn to check whether incoming
593 connection is denied. Affected file silcd/serverconfig.[ch].
595 * Do not check the ports when checking the incoming configuration
596 data if the port is 0, meaning any. Affected file is
597 silcd/serverconfig.c.
599 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Fixed buffer overflow in silc_string_compare in the file
602 lib/silcutil/silcutil.c.
604 * Fixed double free in silc_server_command_leave in the file
607 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
609 * Fixed the version checking in the server. Affected file is
612 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
614 * Fixed the configuration data fetching when accepting new
615 connections in the server. Affected file silcd/server.c.
617 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Added `sender_entry' argument to the function
620 silc_server_packet_relay_to_channel so that we can check
621 whether some destination actually belongs to the same route
622 the sender belongs (ie, we must not resend the packet to the
623 sender). Affected file silcd/packet_send.[ch].
625 * Added `servername' field to the SilcClientEntry in the server
626 to hold the name of the server where client is from. Affected
627 file is silcd/idlist.h.
629 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Moved the channel message encrypting in the router betwen
632 router connections from silc_server_channel_message to the
633 silc_server_packet_relay_to_channel since we want to check
634 whether we have anybody channel before encrypting anything.
635 Affected files silcd/packet_[receive/send].c.
637 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
639 * Fixed the [AdminConnection] server config section to support
640 multiple entries. Affected file silcd/serverconfig.c.
642 * Added support into the server to check the validity of the
643 incoming connection before executing any KE or authentication
646 * The connection configuration is now saved to the KE and
647 connection auth protocol contexts and not fetched anymore in
648 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
650 * The local hosts listenning address and port is also resolved
651 now when starting the server. We want to have the socket object
652 to include the real address and port for the listener. Added
653 new function silc_net_check_local_by_sock into the files
654 lib/silcutil/silcnet.[ch].
656 * Fixed a broadcast bug in server -> do not broadcast if we
659 * Fixed a routing bug. Do not route broadcast packets ever.
660 Broadcast packets must be processed always and not routed since
661 they may be destined to some other host than yourself and thus
662 would get routed without no good reason. Affected file is
665 * Added function silc_server_config_is_primary_route to check
666 whether primary router connection has been configured (a router
667 configuration that we are initiating). If there is not, we
668 will assume that there is only two routers in the SILC network
669 and we will use the incoming router connection as our primary
670 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
672 * Changed the order of the broadcasting. Broadcast _after_ the
673 packet has been processed not before. Affected file is
676 * Fixed a [ClientConnection] parsing bug. The port was never
677 parsed correctly thus resulting to port 0. Affected file
678 silcd/serverconfig.c.
680 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
681 argument and did not set the broadcast packet flag. Affected
682 file silcd/packet_send.c. Fixed same bug in the function
683 silc_server_send_notify as well.
685 * If we receive NEW_ID packet for our own ID in the server, ignore
688 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
692 * Removed the nickname from the Private Message Payload.
693 Updated the code and the protocol specs.
695 * Updated protocol specs for submitting to the IETF.
697 * Tweaked the Random Number Generator a bit. Affected file
698 lib/silccrypt/silcrng.c. Exported a new function
699 silc_rng_[global]_add_noise which can be used to add more
702 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
704 * Do not parse packets with different timeout when protocol
705 is active -> may cause problem with rekey. Affected file
708 * When server receives signoff notify it must not create
709 new channel key if the client is on any channels since the
710 sender of the signoff notify will create it.
712 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
714 * Added printing of error messages during SKE protocol from the
715 failure packet sent by server during SKE. Affected file
718 * Removed the client's failure_callback handling with timeout
719 and handle it immediately when received.
721 * The SKE library returned wrong type in SUCCESS and FAILURE
722 packets. They must be 32 bit MSB not 16 bit MSB.
724 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
726 * Ok, rewrote the logic of the re-key and now it seems to work.
727 I tested it on high traffic with frequent re-keys without
728 problems. Added hmac_receive (and renamed hmac to hmac_send)
729 in SilcClientConnection in lib/silcclient/client.h and
730 in SilcIDListData in silcd/idlist.h. Also, removed the
731 SilcPacketParserContext's cipher and hmac fields as they are
732 not needed anymore and actually caused some problems when
733 the ciphers and hmac's changed underneath the packet parser.
735 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
737 * If re-key protocol is active then process the incoming packets
738 synchronously since we must assure that icoming packets encrypted
739 with the old key is processed before the new keys is set to
740 use. This is true other packets than for REKEY packets.
741 Affected file silcd/server.c. The same was done to client library
742 as well, affected file lib/silcclient/client.c.
744 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
746 * Fixed bug in client and server to accept the force send if
747 the packet is send from silc_[server/client]_packet_process
748 function. Otherwise the packets are never delivered, oops.
750 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
752 * Disable force sending of packets when REKEY protocol is active.
753 We must assure that no packet is sent directly when rekey is
754 performed. All packets must be sent through packet queue.
755 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
756 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
757 function is silc_[server/client]_packet_send_real to check
760 * Replaced the SIM paths from example config files to
761 /usr/local/modules. Also, make install creates now
762 /usr/local/silc/logs directory to hold all the SILC server
765 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
767 * Made the configure.in.pre work on Solaris. Patch by salo.
769 * Made all ciphers compatible with non-x86 machines. Defined
770 CBC mode macros into lib/silccrypt/ciphers_def.h.
772 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
774 * Fixed the make install.
776 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
778 * When MAC computation fails the silc_packet_decrypt returned 0
779 even though it was supposed to return -1. Fixed this. The
780 affected file is lib/silccore/silcpacket.c.
782 * Do not replace the config files in /etc/silc (in make install)
783 if they already exist. Affected file ./Makefile.am.
785 * Do not send re-key packets immediately but through packet queue.
786 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
788 * Changed silc_net_check_host_by_sock to return FALSE if the
789 IP/DNS could not be resolved. Though, it returns the IP address
790 now even if it could not resolve it (but returns also FALSE).
791 Affected file lib/silcutil/silcnet.[ch].
793 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
795 * Added silc_pkcs_decode_identifier to decode the public key's
796 identifier. Affected file lib/silccrypt/silpkcs.[ch].
797 Added also silc_pkcs_free_identifier. Added also new context
798 SilcPublicKeyIdentifier.
800 * Added -S option to the silc client. It is used to dump the
801 contents of the specified public key file.
803 * Changed the PKCS api to return the public key length when
804 setting the public key.
806 * Fixed a fatal bug in the public and private key file loading.
807 Affected file lib/silccrypt/silcpkcs.c.
809 * Execute the packet parsing for client with zero (0) timeout
810 if the protocol is active. Affected file silcd/server.c.
812 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
814 * Made the key generation options to the silcd program. Added
815 -C option, equivalent to client's option.
817 * Added new [ServerKeys] config section to the server. It
818 configures the server's public and private key.
820 * Defined generic Public Key Payload into the protocol
821 specification to send specific type of public keys and
824 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
825 public key or certificate.
827 * Implemented the GETKEY command to the server and to the
828 client library and on user interface.
830 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Made preliminary `make install' work.
834 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Added SilcServerRekey context into silcd/idlist.h.
838 * Added the PFS support as defined in the specification to the
839 SKE protocol. Affected files lib/silcske/*.c.
841 * Added `ske_group' field to the SilcServerRekey context to hold
842 the number of the SKE group that is used with PFS in re-key.
843 Affected file silcd/idlist.h.
845 * Added PFS re-key support to the server. Affected file is
848 * Added silc_protocol_cancel to cancel execution of the next
849 state of the protocol. Affected file is
850 lib/silccore/silcprotocol.[ch].
852 * Added the re-key support with and without PFS to the client
853 library. Re-key is performed once in an hour, by default.
855 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
856 Added silc_client_rekey_callback and silc_client_rekey_final.
857 Affected files are lib/silcclient/protocol.[ch] and
858 lib/silcclient/client.[ch].
860 * Removed the `hmac_key' and `hmac_key_len' fields from the
861 SilcClientConnection structure; not needed. Affected file is
862 lib/silcclient/client.h.
866 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
868 * Do not ask whether user wants to use the negotiated private key
869 for private messages, just use it. Affected file is
870 silc/local_command.c.
872 * Added `send_enc_key' and `enc_key_len' fields to the
873 SilcIDListData structure since they are needed in the re-key
874 phase. Affected file is silcd/idlist.[ch].
876 * Implemented the simple re-key protocol into the server.
877 Affected files silcd/server.c and silcd/protocol.[ch]. The
878 re-key will be performed once in an hour, by default.
880 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
881 Added silc_server_rekey, silc_server_rekey_callback and
882 silc_server_rekey_final.
884 * Removed Tunneled flag from the protocol. Updated the code
885 and the specifications.
887 * Adde `pfs' field to the SilcIDListData to indicate whether
888 the PFS is to be performed in the re-key. Affected file is
891 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
893 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
894 int64 of at least the xintXX size. If void * is less that 4
895 bytes uint32 * will be used. Defined bool as boolean.
897 * Changed _ALL_ unsigned long and unsigned int to uint32,
898 unsgined short to uint16 in the source tree.
900 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
901 not handle clients that has entry->data.registered == FALSE.
902 They are not in the network anymore. Affected file is
905 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
907 * Implemented the sending of the SERVER_SIGNOFF notify in the
908 server. Affected file is silcd/server.c.
910 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
911 Added also silc_notify_payload_encode_args into the
912 lib/silccore/silcnotify.[ch].
914 * Implemented ther SERVER_SIGNOFF notify handling in the server.
915 Affected file silcd/packet_receive.c.
917 * Implemented the SERVER_SIGNOFF notify handling in the client
918 library. Affected file lib/silcclient/client_notify.c. Also,
919 implemnted the printing of the SERVER_SIGNOFF info to the
920 application. Affected file silc/client_ops.c.
922 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
923 if the deleting was successful. Affected file silcd/idlist.[ch].
925 * Added support for public key authentication in the connection
926 authentication protocol in the client library. Affected file
927 lib/silcclient/protocol.c.
929 * Changed the server's silc_idlist_get_clients_by_* interface
930 to support already allocated array so that new entries may be
931 added to pre-allocated array. Affected file silcd/idlist.[ch].
932 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
935 * All command reply functions in the server now calls the
936 pending command callback even if error occured. This way the
937 error will be delivered to the client as well. Affected files
938 silcd/command.c and silcd/command_reply.c.
940 * Fixed INFO command to return local server's info if no server
941 was provided. Affected file lib/silcclient/command.c.
943 * Removed RESTART command for good. Updated the code and the
946 * Rewrote parts of the task system. It is a bit simpler now.
947 Removed unsued task priorities. The affected files are
948 lib/silcutil/silctask.[ch].
950 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
952 * Moved the USERS printing from the library to the application.
953 Affected files lib/silcclient/command.c and silc/client_ops.c.
955 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
959 * Added channel key re-key support. The re-key is perfomed
960 only by the router and is done once in an hour. Added `rekey'
961 field to the SilcChannelEntry in the server. Affected files
962 silcd/server.c and silcd/idlist.h.
964 * Added silc_task_unregister_by_context into the file
965 lib/silcutil/silctask.[ch].
967 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
969 * Added SILC_UMODE_GONE mode to indicate when the client is not
970 present in the SILC network. Added also support to the local
971 command AWAY that will set this mode. Added support of showing
972 "xxx is gone" in WHOIS command. The USERS command shows the
975 * Fixed setting server and router operator privileges in the
976 server's UMODE command. Affected file silcd/command.c.
978 * Merged the SKE KE1 and KE2 payloads into one payload. The
979 new KE payload is equivalent to the old KE2 payload.
981 Cleaned up the SKE Start Payload parsing. It now uses the
982 simple buffer unformatting to do the parsing. A lot faster
985 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
986 to the SKE that is used to indicate whether both of the SKE
987 parties should perform authentication. By default only the
988 responder performs authentication. By setting this flag also
989 the initiator must do authentication. By default it is unset
990 since in normal SKE case, client to server connection, only
991 the responder should do authentication. When doing SKE between
992 two clients both should perform authentication. Updated the
993 code and the protocol specs.
995 * A little fix to IDENTIFY command in the server. Search the
996 client first by hash not nickname. Affected file is
999 * Fixed the silc_client_close_connection to support closing
1000 the client to client connections wihtout deleting too much
1001 data. Affected file lib/silcclient/client.c.
1003 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1004 are received if protocol used to be active but is not anymore
1005 the application would crash due to NULL pointer dereference.
1006 Affected files silcd/server.c and lib/silcclient/client.c.
1008 * Added `hash' field to the SilcClientConnection to include
1009 the hash function negotiated in the SKE protocol.
1011 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1012 to set the channel founder authentication data. A client can
1013 claim the founder rights later by providing the authentication
1014 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1015 This way the channel founder can regain the channel founder
1016 privileges even it is left the channel. This works only on
1017 local server and the client must be connected to the same
1018 server to be able to regain the founder rights. Updated the
1019 protocol specs accordingly.
1021 Added support to the CMODE command in the client to set the
1022 founder auth data. Read the README to see how to set it.
1024 Added support to the CUMODE command to claim the founder
1025 rights. Read the README to see how to do it.
1027 Added support for the founder authentication to the Channel
1028 Entry in the server. Affected file silcd/idlist.h.
1030 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1031 server's CMODE command. Affected file silcd/command.c.
1033 * Added the following new functions into lib/silccore/silcauth.[ch]:
1034 silc_auth_get_method and silc_auth_get_data.
1036 * The server now saves the remote hosts public key to the
1037 SilcIDListData pointer. Affected file silcd/protocol.c.
1039 * The normal server now does not remove the channel entry from
1040 the cache if the founder authentication data is set. It used
1041 to remove it if the founder was the last one on the channel on
1042 the server and left the channel. The auth data is saved and
1043 if the channel is re-joined later the old entry is used with
1044 the old auth data. Affected files silcd/command_reply.c and
1047 * Removed the `pkcs' field from the SilcIDListData structure
1048 in the server; it is not used. Affected file silcd/idlist.h.
1050 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1052 * Fixed packet processing on slow links. Partial packets were
1053 never re-processed because the incoming data buffer was cleared
1054 by the application. Application must not directly clear the
1055 sock->inbuf, the packet processing routines handle it. Fixed
1056 this in client library and in server.
1058 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1060 * Fixed the WHOIS and IDENTIFY send reply function to really
1061 check whether to send list or just one entry. Affected file
1064 * Cleaned up the LEAVE command's channel key distribution. The
1065 affected file silcd/command.c.
1067 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1068 can enforce the channel mode as well. In that case the ID
1069 includes the ID of the server. The code now enforces the
1070 mode change if the router have different mode than the server.
1072 * The notify client operation with CMODE_CHANGE notify can now
1073 return NULL client_entry pointer if the CMODE was not changed
1074 by client. Application must check for this.
1076 * Added <Server ID> argument to INFO command to support server
1077 info fetching by Server ID.
1079 * Added silc_server_announce_get_channel_users to get assembled
1080 packets of channel users of the specified channel. Affected
1081 file silcd/server.[ch].
1083 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1084 was freed underneath the ID Cache.
1086 * Re-announce clients when the server received CHANNEL_CHANGE
1087 notify from the router. Affected file silcd/packet_send.c.
1089 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1091 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1092 crashed since it did not handle the fact that there is no cipher
1093 called "3" and didn't check the error condition. Now fixed.
1095 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1096 flag. It can be used to send message requests.
1098 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Implemented the RESTART command in the client.
1102 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1103 notice type messages. Added notice printing to the user
1106 * The channel keys are not re-generated if the channel's mode
1107 is PRIVKEY, ie private key on the channel exists. Affected
1108 files silcd/server.c and silcd/command.c.
1110 * Fixed a little bug in channel message delivery when channel
1111 private keys are set in the server. Affected file is
1112 silcd/packet_send.c.
1114 * Changed the setting on channel->on_channel = TRUE from the
1115 silc_client_save_channel_key to the JOIN command reply. The
1116 key payload is not received if the private channel key is set.
1117 Affected file lib/silcclient/command_reply.c and the
1118 lib/silcclient/client_channel.c.
1120 * When the CMODE_CHANGE notify is sent and the channel private
1121 key mode is removed the channel key must be re-generated in
1122 other cells as well. Added this support for the router in the
1123 silcd/packet_receive.c.
1125 * Added new local command NOTICE to send notice message on
1126 channel. Affected file silc/local_command.[ch].
1128 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1130 * Added new local command ME to the client. It is used to send
1131 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1132 some action. Affected file silc/local_command.[ch].
1134 * Changed channel_message and private_message client operations
1135 to deliver the message flags to the application. Added also
1136 the `flags' arguments to the silc_client_send_channel_message
1137 and silc_client_send_private_message functions. Affected file
1140 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1142 * Redefined the Private Message Payload to support private message
1143 keys and to support the new private message flags. Updated
1144 the protocol specs. Flags makes it possible to have for example
1145 CTCP style messages.
1147 * Added new type SilcPrivateMessagePayload and defined an API
1148 for it in the lib/silcclient/silcprivate.[ch].
1150 * Tested private message private keys successfully. Tested the
1151 private message key set, unset and list commands with the new
1154 * Redefined the Channel Message Payload to include the channel
1155 message flags (equal with private message flags) to support
1156 for example CTCP style messages.
1158 * Defined some of the message (for channel and private message)
1159 flags. Updated the protocol specs and added the flags to the
1160 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1162 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * Added SilcKeyAgreementStatus type to the key agreement routines
1165 to indicate the current status and error if one occured.
1166 The status types are defined in the lib/silcclient/silcapi.h.
1168 * Added new local command KEY that is used to set and unset private
1169 keys for channels, set and unset private keys for private messages
1170 with remote clients and to send key agreement requests and
1171 negotiate the key agreement protocol with remote client. The
1172 key agreement is supported only to negotiate private message keys,
1173 it currently cannot be used to negotiate private keys for channels,
1174 as it is not convenient for that purpose.
1176 * Fixed a minor pending callback setting bug in the function
1177 silc_client_get_client_by_id_resolve, now the function works.
1178 Affected file lib/silcclient/idlist.c.
1180 * Added function silc_net_get_local_port to get local bound
1181 port by socket. Added to lib/silcutil/silcnet.[ch].
1183 * Added `sockets' and `sockets_count' fields to the SilcClient
1184 object. They hold the sockets of the listenning sockets in
1185 the client. Listenning sockets may be for example the key
1186 agreement server. Affected file lib/silcclient/client.[ch].
1187 Added functions the silc_client_add_socket and the
1188 silc_client_del_socket. They are exported to the application
1191 * Added ~./silc/clientkeys to support other client's public keys.
1193 * Renamed verify_server_key client operation to verify_public_key
1194 and added one argument to indicate the type of the connection
1195 (server, client etc.).
1197 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1199 * Added silc_server_connection_auth_request to handle the
1200 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1201 silcd/packet_receive.[ch].
1203 * Added silc_server_send_connection_auth_request into the
1204 silcd/packet_send.c to send the connection auth request packet.
1206 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1209 * Fixed the public key authentication in responder side in the
1210 server. The `auth_data' pointer includes the SilcPublicKey
1211 not the path to the public key. Affected file silcd/protocol.c.
1213 * Implemented the public key authentication in the initiator side
1214 in the server. Affected file silcd/protocol.c.
1216 * Removed the [RedirectClient] config section from the server
1217 configuration. Is not needed and I don't want to implement it.
1219 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1221 * Cleaned up the CMODE command in the server. It now works
1222 correctly and supports all the modes defined in the protocol.
1223 Affected file is silcd/command.c.
1225 * Added `hmac_name' field to the SilcChannelEntry in the server
1226 to hold the default HMAC of the channel. It can be set when
1227 creating the channel (with JOIN command). Affected files
1230 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1231 type to indicate the change of the current cipher and hmac
1232 on the channel. Client can safely ignore the <cipher> argument
1233 (if it chooses to do so) since the CHANNEL_KEY packet will
1234 force the channel key change anyway. The <hmac> argument is
1235 important since the client is responsible of setting the new
1236 HMAC and the hmac key into use.
1238 * Fixed the CMODE command in the client library as well.
1240 * Tested CMODE command in router environment successfully.
1242 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1244 * Show the version of the remote client (or server) when connecting
1245 to the server. It is logged to the log file. Affected file
1246 is silcd/protocol.c.
1248 * Fixed the KILLED notify handling in the client library. The
1249 client must be removed from all channels when receiving the
1252 Also, do not remove the client entry when giving the KILL
1253 command but when the KILLED notify is received.
1255 * Removed silc_idlist_find_client_by_nickname from the server.
1256 Not needed anymore. Affected files silcd/idlist.[ch].
1258 * Implemented the CHANNEL_CHANGE notify type handling to the
1259 server. Affected file silcd/server.c.
1263 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1265 * Added silc_server_send_notify_invite to send the INVITE
1266 notify between routers.
1268 * Implemented the INVITE command correctly to the server.
1270 * Implemented the INVITE notify type handling in the server.
1272 * Implemented the INVITE command to the client library and on the
1275 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1277 * Added function silc_server_get_client_resolve to find the
1278 client entry by ID from all ID lists and then resolve it
1279 (using WHOIS) if it cannot be found. Affected file is
1282 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1284 * Implemented the BAN command to the client library.
1286 * The JOIN command in the server now checks the invite list
1289 * Changed the silc_command_reply_payload_encode_va and the
1290 silc_command_payload_encode_va to support that if argument is
1291 NULL it ignores and checks the next argument. Affected file
1292 lib/silccore/silccommand.c.
1294 * Added silc_server_send_notify_ban to send the BAN notify
1295 type between routers.
1297 * Chaned the silc_notify_payload_encode to support that if
1298 argument is NULL it ignores and checks the next argument.
1299 Affected file lib/silccore/silcnotify.c.
1301 * Tested ban lists in router environment successfully.
1303 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1305 * Implemented BAN command to the server, in silcd/command.[ch].
1307 * Removed the BAN and INVITE_LIST modes from the CMODE command
1310 * Added function silc_string_match to regex match two strings.
1311 Affected files lib/silcutil/silcutil.[ch].
1313 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1315 * Redefined parts of the SilcChannelEntry in the server to support
1316 the new ban and invite lists.
1318 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1320 * Redefined the INVITE command. The same command can be used to
1321 invite individuals to the channel but also to manage the invite
1322 list of the channel (to add to and remove from the invite list).
1323 Updated the protocol specs.
1325 * Added new command SILC_COMMAND_BAN that can be used to manage
1326 the ban list of the channel. Updated the protocol specs.
1328 * Removed the channel modes: the SILC_CMODE_BAN and the
1329 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1330 in the CMODE command. The equivalent features are now available
1331 using INVITE and BAN commands. Updated the protocol specs.
1333 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1334 in the network about change in the current ban list. The notify
1335 type is not used by the client.
1337 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1338 support the invite lists.
1340 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1342 * Added new function silc_string_regexify that converts string
1343 including wildcard characters into regex string that can
1344 be used by the GNU regex library. Added into the file
1345 lib/silcutil/silcutil.[ch].
1347 Added silc_string_regex_combine to combine to regex strings
1348 into one so that they can be used as one regex string by
1349 the GNU regex library. Added into the file
1350 lib/silcutil/silcutil.[ch].
1352 Added silc_string_regex_match to match two strings. It returns
1353 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1355 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1357 * Imported GNU regex to the soruce tree into lib/contrib.
1358 Fixed some compiler warning from the regex.c.
1360 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1362 * Fixed MOTD command in the server to work in router environment.
1364 * Fixed the MOTD command in the client library to support
1365 the server argument in the command.
1367 * Added `nickname_len' argument to the silc_idlist_add_client
1368 in the server, as the `nickname' argument may be binary data
1371 * Added silc_idlist_get_channels to return all channels from
1374 * Implemented LIST command to the server. Affected file is
1377 * Implemented the LIST command to the client library and on the
1380 * Added [<user count>] argument to the LIST command reply.
1381 With private channels the user count is not shown.
1383 * Updated TODO and README.
1385 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1387 * The client entry's data.registered must be TRUE even with
1388 global client entry on global client list. The data.registered
1389 is used to check whether the client is anymore in the network,
1390 for example with WHOWAS command so it must be valid.
1392 * Fixed the WHOWAS command in the server. It now actually works
1393 in router environment. Added function into silcd/command_reply.c
1394 silc_server_command_reply_whowas_save.
1396 * Added silc_idlist_purge function to the silcd/idlist.c
1397 to periodically purge the ID Cache.
1399 * Fixed INFO command in the server. It works now in router
1400 environment. Added <server name> argument to the INFO command
1401 reply. Updated the protocol specs.
1403 * Fixed minor bug in silc_idcache_purge to not purge if the
1404 expire value is zero.
1406 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1407 they were buggy because of the WHOWAS information.
1409 * Fixed local command MSG to handle the async resolving of
1410 the remote client properly. It used to fail the first MSG.
1411 Affected file silc/local_command.c.
1413 * Added `data_len' field to SilcIDCache context.
1415 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1417 * Update TODO. Todo in commands in the server.
1419 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1421 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1422 used by routers as broadcast packet to inform other routers
1423 about the changed user mode.
1425 Implemented the notify handling in the server. Affected file is
1426 silcd/packet_receive.c. Added the function
1427 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1429 * Added new generic Channel Payload and deprecated the New Channel
1430 Payload. The New Channel Payload is now the generic Channel
1433 * Added new argument `mode' to the silc_server_send_new_channel
1434 as it is required in the Channel Payload now.
1436 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1437 and created a new and real SilChannelPayload to represent the
1438 new generic Channel Payload. Implemented the encode/decode
1439 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1441 * Added silc_server_get_client_channel_list to return the list
1442 of channels the client has joined for WHOIS command reply.
1443 Affected file silcd/server.[ch].
1445 * Implemented the channel list sending in the WHOIS command reply
1446 in server and in the client.
1448 Implemented the channel list displaying on the user interface
1449 as well. Affected file silc/client_ops.c.
1451 * Added silc_channel_payload_parse_list to parse list of Channel
1452 Payloads. It returns SilcDList list of SilcChannelPayloads.
1453 Client for example can use this function to parse the list of
1454 channels it receives in the WHOIS command reply. The caller
1455 must free the list by calling silc_channel_payload_list_free.
1456 Affected files lib/silccore/silcchannel.[ch].
1458 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1460 * Added one new argument <user mode> to the WHOIS command reply
1461 to return the mode of the user in SILC. Updated the protocol
1464 Implemented it to the server and client.
1466 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1468 * Fixed the mode printing on the user interface on joining.
1469 Affected file silc/client_ops.c.
1471 * Implemented the UMODE command and user modes in general to the
1472 client library and to the user interface.
1474 * Implemented the UMODE command to the server.
1476 * The server now sends UNKNOWN_COMMAND error status if client sends
1477 unknown command. Affected file silcd/command.c.
1479 * All server commands now handle the command identifier the right
1480 way when sending the command reply to the client. The client can
1481 use to identify the command replies with the identifier.
1483 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1485 * Added silc_server_get_client_route to resolve the route to
1486 the client indicated by the client ID. Affected file is
1489 * Added silc_server_relay_packet as general function to relay
1490 packet to arbitrary destination. This deprecates functions
1491 like _send_private_message_key, _relay_notify etc. Affected
1492 file is silcd/packet_send.[ch].
1494 Removed silc_server_send_key_agreement,
1495 silc_server_send_private_message_key and
1496 silc_server_packet_relay_notify functions from the file
1497 silcd/packet_send.[ch].
1501 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1502 server. Affected file silcd/packet_receive.[ch].
1504 * Implemented the KILL command to the client. Implemented the
1505 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1506 Affected files lib/silcclient/command[_reply].c and
1507 lib/silcclient/client_notify.c. Implemented the KILL notify
1508 printing in the user inteface.
1510 * Fixed a lot silc_parse_nick memory leaks from the client
1511 library in the file lib/silcclient/command.c.
1513 * Changed the silc_server_send_notify_on_channels's `sender'
1514 argument from SilcSocketConnection to SilcClientEntry to
1515 check the sender as entry and not as connection object and not
1516 to send to the client provided as argument. The affected file
1517 is silcd/packet_send.[ch].
1519 * The notify packets that are destined directly to the client used
1520 to not to be processed by the server. Now changed that and the
1521 server processes all notify packets. After relaying the packet
1522 to the client the notify packet is processed in the server.
1524 * The silc_server_free_client_data now checks whether there is
1525 pending outgoing traffic for the client and purges the data to
1526 the network before removing the client entry.
1528 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1530 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1531 an client is killed from the SILC Network. Updated the protocol
1534 Added new function silc_server_send_notify_killed to the
1535 silcd/packet_send.[ch].
1537 * Added function silc_server_packet_relay_notify to relay notify
1538 packets that are destined directly to a client. In this case
1539 the server does not process the notify packets but merely relays
1540 it to the client. Affected file silcd/packet_send.[ch].
1542 Added also silc_server_packet_process_relay_notify to check
1543 whereto relay the notify. Affected file is
1544 silcd/packet_receive.[ch].
1546 * Implemented the KILL command to the server.
1550 * Added the backup schema desgined last fall to the protocol
1551 specs for everyone to see. The specification is in the
1552 *-spec-xx.txt draft and the packet type definitions for the
1553 backup routers is in *-pp-xx.txt draft. Thusly, added also
1554 new packet type SILC_PACKET_CELL_ROUTERS.
1556 * A big security problem in the implementation discovered. The
1557 signoff of an client did not cause new channel key generation
1558 which it of course should've done. The channel keys must be
1559 always re-generated when client leaves (or signoffs) the channel.
1560 The silc_server_remove_from_channels funtion now handles
1561 the channel key re-generation.
1563 * Added `sender' argument to the silc_server_send_notify_on_channels
1564 to not to send the client provided as argument. Affected file
1565 silcd/packet_send.[ch].
1567 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1569 * Implemented OPER and SILCOPER commands into the server and
1572 * Added silc_auth_verify and silc_auth_verify_data to verify
1573 the authentication directly from the authentication payload.
1574 It supports verifying both passphrase and public key based
1575 authentication. Affected file lib/silccore/silcauth.[ch].
1577 * Added `hash' field to the SilcIDListData structure. It is the
1578 hash negotiated in the SKE protocol. Affected file is
1581 * Slight redesigning of the SilcAuthPayload handling routines.
1582 Do not send SilcPKCS but SilcPublicKey as argument.
1584 * Implemented the public key authentication support to the
1585 serverconfig. The public key is loaded from the provided path
1586 and saved as authentication data to void * pointer. Thus,
1587 changed the unsigned char *auth_data to void *auth_data;
1589 * Fixed SHUTDOWN command to send the reply before the server
1590 is shutdown. :) Affected file silcd/command.c.
1592 * Fixed fatal bug in CONNECT command. The hostname was invalid
1593 memory and server crashed. Affected file silcd/command.c.
1595 * Fixed fatal bug in CLOSE command. The server_entry became
1596 invalid but was referenced later in the command. Affected file
1599 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1601 * Fixed fatal bug in failure packet handling. Server ignored
1602 the failure and thus crashed when it came.
1606 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1608 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1609 that the command may be executed only once in (about) 2 seconds.
1610 The old SILC_CF_LAG flag is same but allows command bursts up
1611 to five before limiting.
1613 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1614 server code. Various commands now includes the CF_LAG_STRICT
1615 flag to disallow any kind of miss-use of the command.
1617 * Fixed the silc_buffer_unformat to not to allocate any data
1618 if the length of the data is zero. It used to allocate the
1619 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1621 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1623 * Changed the format of AdminConnection configuration section
1624 in the server. Added username of the admin to the format.
1625 Affected files silcd/serverconfig.[ch].
1627 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1628 to return admin configuration data by host, username and/or
1631 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1633 * Implemented WHOWAS command to the server. Added the functions:
1635 silc_server_command_whowas_parse,
1636 silc_server_command_whowas_send_reply,
1637 silc_server_command_whowas_from_client and
1638 silc_server_command_whowas_from_server
1640 * Added <Client ID> argument to the WHOWAS command reply. Updated
1641 the protocol specs accordingly.
1643 * Implemented WHOWAS command and command_reply to the client
1646 Implemented the WHOWAS printing on the user interface.
1648 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1650 * Added new argument to the WHOWAS command reply, the real name.
1651 It is an optional argument. Updated the protocol specs.
1653 * Added SilcIDCacheDestructor callback that is registered when
1654 the SilcIDCache is allocated. The callback is called when
1655 an cache entry in the ID Cache expires, or is purged from the
1656 cache. Added into lib/silccore/idcache.[ch].
1658 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1659 to destruct the client entries when the cache entry expires.
1660 Other ID Cache's in server and in the client library ignores
1663 * If the ID Cache entry's `expire' field is zero then the entry
1664 never expires. Added boolean `expire' argument to the
1665 silc_idcache_add function in the lib/silccore/idcache.[ch].
1666 If it is TRUE the default expiry value is used.
1668 * Added silc_server_free_client_data_timeout that is registered
1669 when client disconnects. By default for 5 minutes we preserve
1670 the client entry for history - for WHOWAS command.
1672 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1674 * Added support to the server to enforce that commands are not
1675 executed more than once in 2 seconds. If server receives
1676 commands from client more frequently, timeout is registered
1677 to process the commands. Affected file silcd/command.c.
1678 Added new function silc_server_command_process_timeout.
1680 * Changed NICK_NOTIFY handling in client library to check that
1681 if the client's nickname was changed, so there is no need to
1682 resolve anything from the server.
1684 * Removed error printing from the WHOIS and IDENTIFY commands.
1685 If error occurs then it is ignored silently in the client library.
1686 The application, however, may map the received error to
1687 human readable error string. The application currently maps
1688 the NO_SUCH_NICKNAME error to string.
1690 * Made the command status message public to the application. Moved
1691 them from lib/silcclient/command_reply.c to
1692 lib/silcclient/command_reply.h. The application can map the
1693 received command status to the string with the
1694 silc_client_command_status_message function.
1696 * Added check to the server to check that client's ID is same
1697 as the Source ID in the packet the client sent. They must
1700 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1702 * Added dist-bzip hook to the Makefile.am to make bzip2
1703 compressed distributions.
1705 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1707 * Server now enforces the maximum length for the nickname and
1708 the channel as protocol specification dictates. 128 bytes for
1709 nickname and 256 bytes for channel name.
1711 * Moved the WHOIS printing to the application. The client libary
1712 does not print out the WHOIS information anymore, the application
1713 must do it. Renamed silc_client_command_reply_whois_print to
1714 the silc_client_command_reply_whois_save.
1716 The client's idle time is also sent to the application now, and
1717 the idle is shown on screen.
1719 * Added silc_client_command_reply_identify_save to save the
1720 received IDENTIFY entries.
1722 * Do not check for channel private keys in message sending and
1723 reception if the channel does not have the PRIVKEY mode set.
1724 Affected file lib/silclient/client_channel.c.
1726 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1728 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1729 just surfaced after chaning the JOIN procedure.
1731 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1733 * Added silc_client_get_clients_by_list to get client entries
1734 from Client ID list, that is returned for example by JOIN
1735 and USERS command replies. The application should use this
1736 function for example when JOIN command reply is received to
1737 resolve the clients already on the channel (library does not
1738 do that anymore as USERS command reply is not used in the JOIN
1739 procedure anymore). Affected files lib/silcclient/silcapi.h and
1740 lib/silcclient/idlist.c.
1742 * JOIN command reply and USERS command reply returns now SilcBuffer
1743 pointers instead of unsigned char pointers when returning
1744 the client list and mode list.
1746 * Added <Client ID> argument to the JOIN command reply, mainly
1747 for the server to identify for which client the command was
1748 originally sent. Updated protocol specs accordingly.
1750 * Added SilcDlist private_key pointer to the SilcChannelEntry
1751 in the client to support the channel private keys. Affected
1752 file is lib/silcclient/idlist.h.
1754 * Added SilcChannelPrivateKey argument to the function
1755 silc_client_send_channel_message so that application can choose
1756 to use specific private ke if it wants to. If it is not provided,
1757 the normal channel key is used, unless private keys are set.
1758 In this case the first (key that was added first) is used
1759 as the encryption key.
1761 * Implemented the support for channel private key handling.
1762 Implemented the following functions:
1764 silc_client_add_channel_private_key,
1765 silc_client_del_channel_private_keys,
1766 silc_client_del_channel_private_key,
1767 silc_client_list_channel_private_keys and
1768 silc_client_free_channel_private_keys
1770 Affected file lib/silcclient/client_channel.c.
1772 * Added the support for the private keys in the channel message
1773 sending and encryption and in the message reception and
1774 decryption. Affected funtions are
1775 silc_client_send_channel_message and silc_client_channel_message.
1777 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1779 * Added SKE's key verify callback to the client library's
1780 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1782 * Removed the statement that server (or router) must send USERS
1783 command reply when joining to the channel so that the client
1784 knows who are on the channel. Instead, the client list and
1785 client's mode list is now sent in the JOIN command reply to the
1786 client who joined channel. This is better solution.
1788 * Added function silc_server_get_users_on_channel and function
1789 silc_server_save_users_on_channel to the silcd/server.[ch].
1791 * Removed function silc_server_command_send_users from the
1794 * Do not show topic on the client library anymore. The topic is
1795 sent in the command reply notify to the application and the
1796 application must show the topic now.
1798 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1800 * Added client searching by nickname hash into the IDENTIFY and
1801 WHOIS commands in the server as they were clearly missing from
1802 them. Affected file is silcd/command.c.
1804 * Fixed a bug in private message receiving in the client library.
1805 The remote ID was freed and it wasn't supposed, now it is
1808 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1810 * Minor fix to the channel payload; allocate the data area, as it
1811 needs to be of specific length.
1813 * If the key agreement port is zero then the operating
1814 system will define the bound port. Affected files are
1815 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1817 * Added new function silc_channel_payload_decrypt into the file
1818 lib/silccore/silcchannel.[ch].
1820 * Moved the channel message etc, check from silc_packet_decrypt
1821 to applications. The library calls now a generic
1822 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1823 when the packet is either normal or special. This was done to
1824 allow more wide range of checking that was not allowed when
1825 the code was in library. Now applications can do virtually any
1826 checks to the packet and return to the library the decision how
1827 the packet should be processed. Affected files are
1828 lib/silccore/silcpacket.[ch].
1830 Added silc_server_packet_decrypt_check to the server and
1831 silc_client_packet_decrypt_check to the client library.
1833 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1834 to send with specified source and destination information.
1836 * Channel message delivery between routers was broken after the
1837 channel key distribution was fixed earlier. The channel key
1838 was used be to distributed to other routers as well which is not
1839 allowed by the protocol. Now this is fixed and channel keys
1840 really are cell specific and the channel message delivery between
1841 routers comply with the protocol specification.
1843 * Fixed various commands in server to check also the global list
1844 for the channel entry and not just the local list. The affected
1845 file silcd/command.c.
1847 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1849 * Added assert()s to buffer formatting and unformatting routines
1850 to assert (if --enable-debug) when error occurs. Affected
1851 file: lib/silcutil/silcbuffmt.c.
1853 * Changed to auto-reconnect to check whether the remote host is
1854 router and register the re-connect timeout if it is. It used
1855 to check that whether we are normal server, but router must do
1856 auto-reconnect with another router as well. Affected file
1859 * Removed the [<key len>] option from CMODE command as the cipher
1860 name decides the key length, nowadays. See the defined ciphers
1861 from the protocol specification.
1863 * Added [<hmac>] option to the CMODE command to define the HMAC
1864 for the channel. Added SILC_CMODE_HMAC channel mode.
1866 * Added [<hmac>] option for the JOIN command so that user can
1867 select which HMAC is used to compute the MACs of the channel
1870 * Added Hmac field to the Channel Message Payload. The integrity
1871 of plaintext channel messages are now protected by computing
1872 MAC of the message and attaching the MAC to the payload. The
1873 MAC is encrypted. Now, it is clear that this causes some
1874 overhead to the size of the packet but rationale for this is that
1875 now the receiver can verify whether the channel message decrypted
1876 correctly and also when private keys are set for the channel the
1877 receiver can decrypt the packet with several keys and check from
1878 the MAC which key decrypted the message correctly.
1880 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1881 lib/silccrypt/silccipher.[ch].
1883 * Added silc_hash_len to return the digest length into the
1884 lib/silcrypt/silchash.[ch].
1886 * Rewrote parts of Silc Channel Payload interface in the
1887 lib/silccore/silcchannel.[ch]. The encode function now also
1888 encrypts the packet and parse function decrypts it.
1890 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1892 * Fixed a minor formatting bug in the SKE's key material processing.
1893 It actually might have processed the keys wrong way resulting
1896 * Redefined the mandatory HMAC algorithms and added new algorithms.
1897 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1898 and hmac-md5 truncated to 96 bits. The mandatory is now
1899 hmac-sha1-96. Rest are optional (including the one that used
1900 to be mandatory). Rationale for this is that the truncated HMAC
1901 length is sufficient from security point of view and can actually
1902 make the attack against the HMAC harder. Also, the truncated
1903 HMAC causes less overhead to the packets. See the RFC2104 for
1906 * Added new [hmac] configuration section. The SKE used to use
1907 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1908 is of course wrong. The official names that must be proposed in
1909 the SKE are the ones defined in the protocol specification
1910 (hmac-sha1-96 for example). The user can configure any hmac
1911 using any hash function configured in the [hash] section. At
1912 least, the mandatory must be configured.
1914 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1916 * Added HMAC list to the SKE proposal list. It has now both
1917 hash algorithm list and HMAC list. This makes the protocol
1918 incompatible with previous versions. The SKE now seems to work
1919 the way it is supposed to work, for the first time actually.
1921 * Defined plain Hash algorithms to the protocol specification.
1924 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1926 * Implemented support for key agreement packets into the server.
1927 Added functions silc_server_key_agreement and
1928 silc_server_send_key_agreement. Other than these functions,
1929 server has nothing to do with this packet.
1931 * Added support for private message key packets into the server.
1932 Added functions silc_server_private_message_key and
1933 silc_server_send_private_message_key.
1937 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1938 called in the protocol's final callback instead in the END
1939 protocol state. This makes a little more sense and in the same
1940 time in client we can use the same protocol routines for normal
1941 key exchange and to key agreement packet handling as well.
1943 * Added to both client's and server's KE protocol context the
1944 SilcSKEKeyMaterial pointer to save the key material. We will
1945 bring the key material to the protocol's final callback by doing
1946 this. The final callback must free the key material.
1948 * Added SKE's packet_send callback into client's KE protocol
1949 context so that the caller can choose what packet sending function
1950 is used. This way we can use different packet sending when
1951 doing normal SKE when doing key agreement packet handling (in
1952 the key agreement packet handling we do not want to encrypt
1955 * Implemented the responder side of the key agreement routines
1956 in the client. The client can now bind to specified port and
1957 accept incoming key negotiation. The key material is passed
1958 to the application after the protocol is over.
1960 * Implemented the processing of incoming Key Agreement packet
1961 in the client. Added function silc_client_key_agreement to
1964 * Implemented the intiator side of the key agreement routines
1965 in the client. The client can now initiate key agreement with
1966 another remote client. The key material is passed to the
1967 application after the protocol is over.
1969 * Created client_keyagr.c to include all the key agreement
1972 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1973 SILC_TASK_CALLBACK except that it is not static.
1975 * Created client_notify.c and moved the Notify packet handling
1976 from the client.[ch] into that file.
1978 * Created client_prvmsg.c and moved all private message and
1979 private message key routines from the client.[ch] into that file.
1981 * Create client_channel.c and moved all channel message and
1982 channel private key routines from the client.[ch] into that file.
1984 * Changed silc_client_get_client_by_id_resolve to resolve with
1985 WHOIS command instead of IDENTIFY command, in the file
1986 lib/silclient/idlist.c.
1988 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1990 * Implemented the SKE's responder side to the Client library.
1992 * When FAILURE is received to the protocol do not trust it
1993 blindly. Register a timeout to wait whether the remote closes
1994 the connection as it should do it, only after that process the
1995 actual failure. This was changed to both client and server.
1997 * Added client_internal.h to include some of the structures
1998 there instead of client.h in lib/silcclient/.
2000 * Added function silc_task_unregister_by_callback to unregister
2001 timeouts by the callback function.
2003 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2005 * Some "Incomplete WHOIS info" errors has been appearing on the
2006 log files. Took away the entry->userinfo check from WHOIS
2007 reply sending. The entry->userinfo is now " " if client did not
2008 provide one. I thought this was fixed earlier but something
2009 is wrong still. Let's see if the error still appears.
2011 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2013 * Fixed a minor bug in the login when the channel key is
2014 re-generated in the server. It used to generate the key in
2015 wrong order and thus caused problems in the channel traffic.
2017 * Fixed a minor bug in channel key distsribution after
2018 KICK command. The key was not sent to the router even though
2021 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2023 * Added silc_ske_process_key_material_data as generic routine
2024 to process any key material as the SILC protocol dictates. The
2025 function is used by the actual SKE library but can be used by
2026 applications as well. This relates to the private message keys
2027 and the channel private keys since they must be processed the
2028 same way the normal SILC session keys. The protocol dictates
2029 this. Affected files: lib/silcske/silcske.[ch].
2031 Added also silc_ske_free_key_material to free the
2032 SilcSKEKeyMaterial structure.
2034 * Defined silc_cipher_set_key function to set the key for
2035 cipher without using the object's method function. The affected
2036 files: lib/silccrypt/silccipher.[ch].
2038 * Implemented silc silc_client_add_private_message_key,
2039 silc_client_add_private_message_key_ske,
2040 silc_client_del_private_message_key,
2041 silc_client_list_private_message_keys and
2042 silc_client_free_private_message_keys functions in the
2045 Added functions silc_client_send_private_message_key to send
2046 the Private Message Key payload and silc_client_private_message_key
2047 to handle incoming Private Message Key payload.
2049 * Added Cipher field to the Private Message Key payload to set
2050 the cipher to be used. If ignored, the default cipher defined
2051 in the SILC protocol (aes-256-cbc) is used.
2053 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2055 * Removed lib/silcclient/ops.h file.
2057 Redefined parts of the SILC Client Library API. Created new
2058 file silcapi.h that deprecates the ops.h file and defines the
2059 published Client Library API. Defined also private message key
2060 API and channel private key API into the file.
2062 This is the file that the application must include from the
2063 SILC Client Library. Other files need not be included by
2064 the application anymore.
2066 * Added new key_agreement client operation callback and also
2067 defined the Key Agreement library API for the application.
2069 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2071 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2072 is used by clients to request key negotiation between another
2073 client in the SILC network. If the negotiation is started it
2074 is performed using the SKE protocol. The result of the
2075 negotiation, the secret key material, can be used for example
2076 as private message key.
2078 Implemented the Key Agreement payload into the files
2079 lib/silccore/silauth.[ch].
2081 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2083 * Redefined ciphers for the SILC protocol. Added some new ciphers
2084 and defined the key lengths for the algorithms. Changed the
2085 code accordingly. The default key length is now 256 bits.
2087 * Fixed SKE key distribution function silc_ske_process_key_material
2088 when the key length is more than 128 bits. The default key
2089 length in SILC is now 256 bits.
2091 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2092 to indicate unsupported algorithm.
2094 * Renamed rijndael.c to aes.c and all functions as well.
2096 * Fixed a long standing channel key setting bug in client library.
2097 Weird that it has never surfaced before.
2099 * Fixed bug in channel deletion. If the entire channel is removed
2100 then it must also delete the references of the channel entry
2101 from the client's channel list as the client's channel entry and
2102 the channel's client entry share same memory.
2104 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2106 * Implemented CONNECT and SHUTDOWN commands in the client.
2108 * Implemented CLOSE command to the client.
2110 * Added the function silc_idlist_find_server_by_name into the
2111 files silcd/idlist.[ch].
2113 Added the function silc_idlist_find_server_by_conn into the
2114 files silcd/idlist.[ch].
2116 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2118 * DIE command was renamed to SHUTDOWN. Updated the both code
2121 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2122 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2124 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2127 * Added function silc_server_create_connection function to create
2128 connection to remote router. My server implementation actually
2129 does not allow router to connect to normal server (it expects
2130 that normal server always initiates the connection to the router)
2131 so the CONNECT command is only good for connecting to another
2134 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2136 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2137 or some other client was kicked from the channel.
2139 Implemented the handling of the notify type to both client
2142 Implemented silc_server_send_notify_kicked to send the KICKED
2143 notify. It is used to send it to the server's primary router.
2145 * Implemented the KICK command into server and client.
2147 * Added `query' argument to the silc_idlist_get_client function
2148 to indicate whether to query the client from server or not if
2151 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2152 to indicate that the client is not channel founder.
2156 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2158 * Removed the rng context from SilcPacketContext structure and
2159 changed that the packet routine uses the Global RNG API.
2161 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2163 * Added support for quit message that client can "leave" on the
2164 channel when it quits the SILC. It is ditributed inside the
2165 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2167 Added silc_server_free_client_data that will take the
2168 signoff message as argument.
2170 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2172 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2174 * Updated parts of the protocol specification to keep it up
2177 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2179 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2180 payloads in one packet.
2182 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2183 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2184 use now the new List flag.
2186 * Also deprecated the following packet types: REPLACE_ID,
2187 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2189 * Added list support for Notify packet in server.
2191 * Added silc_server_send_notify_channel_change to send the
2192 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2193 the silc_server_send_replace_id.
2195 * Added silc_server_send_notify_nick_change to send the
2196 NICK_CHANGE notify type. Deprecates the function
2197 silc_server_send_replace_id.
2199 * Added silc_server_send_notify_join to send the JOIN notify type.
2200 Deprecates the function silc_server_send_new_channel_user.
2202 * Added silc_server_send_notify_leave to send LEAVE notify type.
2203 Deprecates the function silc_server_send_remove_channel_user.
2205 * Added silc_server_send_notify_cmode and
2206 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2207 types. Deprecates the silc_server_send_set_mode function.
2209 * Added SERVER_SIGNOFF notify type to indicate that server has
2210 quit. This means that all clients on the channel from that
2211 server will drop. This can be also used when netsplit happens.
2213 Deprecated REMOVE_ID packet type since it is not needed anymore
2216 Added silc_server_send_notify_server_signoff to send the
2217 SERVER_SIGNOFF notify type. Deprecates the function
2218 silc_server_send_remove_id.
2220 Added also silc_server_send_notify_signoff to send the
2221 SIGNOFF notify type.
2223 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2224 SILC protocol from this day on. Changed the protocol
2225 specification as well.
2227 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2228 notify type. It is used between routers to notify about
2229 topic changes on a channel.
2231 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2234 * Partly updated the protocol specification to comply with the
2235 changes now made. It is still though a bit outdated.
2237 * The JOIN notify type now takes one extra argument <Channel ID>.
2238 The packet used to be destined to the channel but now the
2239 JOIN type may be sent as list thus it is impossible to
2240 destine it to any specific channel. By adding this argument
2241 it is again possible.
2243 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2245 * Added CREDITS file. The CHANGES and CREDITS file will appear
2246 in the distribution as well.
2248 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2250 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2251 types in the server's silcd/packet_receive.c.
2253 * Implemented CMODE and CUMODE to work in router environment.
2255 * Fixed minor encoding and decoding buglet from the
2256 lib/silccore/silcmode.c.
2258 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2261 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2263 * Changed all SilcConfigServer* and silc_config_server* to
2264 SilcServerConfig* and silc_server_config*, respectively.
2267 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2269 * Associated the ID (client or server ID) to the Authentication
2270 Payload to avoid any possibility of forging. Updated the
2271 protocol specification and the code accordingly.
2273 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2275 * The RSA key length is now save to the RsaKey context in the
2276 key generation process in lib/silccrypt/rsa.c. The key length
2277 is now used to figure out the maximum size of the block allowed
2278 to be encrypted/signed.
2280 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2281 is equivalent to the silc_mp_mp2bin but does not allocate any
2284 * Changed silc_mp_mp2bin API to take length argument. If it is
2285 non-zero then the buffer is allocated that large. If zero, then
2286 the size is approximated using silc_mp_sizeinbase, which however
2289 * Created Global RNG API which is global RNG that application can
2290 initialize. After initializing, any routine anywhere in the
2291 code (including library) can use RNG without allocating a new
2292 RNG object. This was done to allow this sort of use of the
2293 RNG in code that has no chance to allocate RNG object. All
2294 applications currently allocate this and many routines in the
2295 library use this. Affected file lib/silccrypt/silcrng.[ch].
2297 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2298 it to use the Global RNG API.
2300 * Defined Authentication Payload into protocol specification that
2301 is used during SILC session to authenticate entities. It is
2302 used for example by client to authenticate itself to the server
2303 to obtain server operator privileges.
2305 Implemented this payload into the lib/silccore/silcauth.[ch].
2306 Implemented also routines for public key based authentication
2307 as the new protocol specification dictates.
2309 Moved definitions of different authentication methods from
2310 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2312 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2313 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2314 silc_pkcs_verify_with_hash functions into the file
2315 lib/silccrypt/silcpkcs.[ch].
2317 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2319 * The client entry's userinfo pointer must be always valid.
2320 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2321 will fail since it requires the userinfo. Now, the userinfo
2322 is allocated as "" if actual userinfo does not exist. Actually,
2323 it must exist and it is totally Ok to drop client connections
2324 that does not announce the userinfo. However, we will make
2325 this workaround for now.
2327 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2328 to return the remote port by socket.
2330 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2333 SILC_SERVER_PENDING_EXEC and added an new macro
2334 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2335 data or when error occurs while processing the pending command.
2337 Added new argument `destructor' into silc_server_command_pending
2338 and to the SilcServerCommandPending object. This destructor is
2339 now called after calling the pending callback or if error occurs
2340 immediately. If error occurs the actual pending callback won't
2341 be called at all - only the destructor. The destructor may be
2342 NULL if destructor is not needed.
2344 All this applies for client library code as well. Similar
2345 changes were made there as well for the pending commands.
2347 In the client, the application must now allocate the
2348 SilcClientCommandContext with the silc_client_command_alloc
2351 * Added reference counter to the SilcServerCommandContext. Added
2352 function silc_server_command_alloc and silc_server_command_dup
2355 Same type of functions added to the client library for the same
2358 * Removed the cmd_ident from IDListData away since it is now
2359 global for all connections. It is the command identifier used
2360 in command sending and with pending commands. The affected file
2363 * Added reference counter to the SilcSocketConnection objecet to
2364 indicate the usage count of the object. The object won't be
2365 freed untill the reference counter hits zero. Currently only
2366 server uses this, and client ignores it. The client must be
2367 set to use this too later. The affected files are
2368 lib/silccore/silcsockconn.[ch]. Added also the function
2369 silc_socket_dup to increase the reference counter.
2371 This was mainly added because it is possible that the socket
2372 is removed underneath of pending command or other async
2373 operation. Now it won't be free'd and proper DISCONNECTING
2374 flags, etc. can be set to avoid sending data to connection that
2375 is not valid anymore.
2377 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2378 the connection. After that it sets SILC_SET_DISCONNECTED.
2379 It is, however, possible that the socket data is not still freed.
2380 The silc_server_packet_process now checks that data is not
2381 read or written to connection that is DISCONNECTED. The socket
2382 get's freed when the reference counter hits zero.
2384 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2386 * Changed the client operation API: channel_message operation's
2387 `sender' is now the client entry of the sender, not the nickname
2388 and the `channel' is the channel entry, not the channel name.
2390 In the private_message operation the `sender' is now also the
2391 client entry of the sender not the nickname.
2393 Affected file is lib/silcclient/ops.h and all applications
2394 using the client operations.
2396 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Moved the calling of ops->connect() from connect_to_server_final
2399 into receive_new_id functin since that is the point when the
2400 client is actually allowed to send traffic to network. The
2401 affected file is lib/silcclient/client.c.
2403 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2405 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2406 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2407 (if needs broadcasting) instead of broadcasting the packets one
2408 by one which would make a burst in the network traffic.
2410 * Added `broadcast' argument to the functions in silcd/server.[ch]
2411 silc_server_create_new_channel[_with_id] to indicate whether
2412 to send New Channel packet to primary router.
2414 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2416 * Added new function into the silcd/server.[ch] files:
2417 silc_server_create_new_channel_with_id to create new channel with
2418 already existing Channel ID.
2420 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2421 lib/silccore/silcpacket.h. This packet is used t send list of
2422 Set Mode payloads inside one packet. Server uses this to set
2423 the modes for the channels and clients on those channels, that it
2424 announced to the router when it connected to it. The protocol
2425 specification has been updated accordingly.
2427 * The silc_server_new_channel did not handle the packet coming
2428 from normal server as it normally does not send that. However,
2429 when it announces its channels it does send it. Implemented
2430 the support for that.
2432 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2433 into the file lib/silccore/id.h.
2435 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Fixed memory leaks in the functions silc_idlist_del_client,
2438 silc_idlist_del_channel and silc_idlist_del_server in the file
2439 silcd/idlist.c. All of those leaked like a sieve.
2441 * Fixed some small memory leaks in the client's function
2442 silc_client_notify_by_server.
2444 * Added functions into silcd/server.c: silc_server_announce_clients,
2445 silc_server_announce_channels and silc_server_announce_server.
2446 These functions are used by normal and router server to announce
2447 to its primary router about clients, channels and servers (when
2448 router) that we own. This is done after we've connected to the
2451 These functions effectively implements the following packet types:
2452 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2453 and SILC_PACKET_NEW_ID_LIST.
2455 * Added new functions into the silcd/packet_receive.[ch]:
2456 silc_server_new_id_list, silc_server_new_channel_list and
2457 silc_server_new_channel_user_list to handle the incoming
2458 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2460 * Added support of changing Channel ID in the function
2461 silc_server_replace_id. If the server that announces a channel
2462 to the router already exists in the router (with same name but
2463 with different Channel ID), router is responsible to send
2464 Replace ID packet to the server and force the server to change
2465 the Channel ID to the one router has.
2467 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2468 client that the Channel ID has been changed by the router. The
2469 normal server sends this to the client. Client must start using
2470 the new Channel ID as the channel's ID.
2472 Implemented handling of this new type into lib/silcclient/client.c
2473 into the function silc_client_notify_by_server.
2475 * Added new function silc_idlist_replace_channel_id into the files
2476 silcd/idlist.[ch] to replace the Channel ID.
2478 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Call silc_server_command_identify_check always when processing
2481 the IDENTIFY command in silcd/command.c
2483 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2486 send keepalive packets. The packet can be sent by clients,
2487 servers and routers.
2489 Added function silc_socket_set_heartbeat into the file
2490 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2491 If not set, the heartbeat is not performed. The actual
2492 heartbeat is implemented in the low level socket connection
2493 library. However, application is responsible of actually
2496 Added silc_server_send_heartbeat to send the actual heartbeat
2497 packet into silcd/packet_send.[ch]. Server now performs
2498 keepalive with all connections.
2500 * Added silc_task_get_first function into lib/silcutil/silctask.c
2501 to return the timeout task with shortest timeout. There was a bug
2502 in task unregistration that caused problems. TODO has been
2503 updated to include that task system must be rewritten.
2505 * The client library will now resolve the client information when
2506 receiving JOIN notify from server for client that we know but
2507 have incomplete information.
2509 * Rewrote parts of silc_server_remove_from_channels and
2510 silc_server_remove_from_one_channel as they did not remove the
2511 channel in some circumstances even though they should've.
2513 * Encryption problem encountered in server:
2515 The LEAVE command used to send the Channel Key packet to the
2516 router immediately after generating it. However, the code
2517 had earlier sent Remove Channel user packet but not immediately,
2518 ie. it was put to queue. The order of packets in the router
2519 was that Channel Key packet was first and Remove Channel User
2520 packet was second, even though they were encrypted in the
2521 reverse order. For this reason, MAC check failed. Now, this
2522 is fixed by not sending the Channel Key packet immediately but
2523 putting it to queue. However, this is more fundamental problem:
2524 packets that are in queue should actually not be encrypted
2525 because packets that are sent immediately gets encrypted
2526 actually with wrong IV (and thus MAC check fails). So, packets
2527 that are in queue should be encrypted when they are sent to
2528 the wire and not when they put to the queue.
2530 However, the problem is that the current system has not been
2531 designed to work that way. Instead, the packet is encrypted
2532 as soon as possible and left to the queue. The queue is then
2533 just purged into wire. There won't be any fixes for this
2534 any time soon. So, the current semantic for packet sending
2537 o If you send packet to remote host and do not force the send
2538 (the packet will be in queue) then all subsequent packets to the
2539 same remote host must also be put to the queue. Only after the
2540 queue has been purged is it safe again to force the packet
2543 o If you send all packets immediately then it safe to send
2544 any of subsequent packets through the queue, however, after
2545 the first packet is put to queue then any subsequent packets
2546 must also be put to the queue.
2548 Follow these rules and everything works fine.
2550 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Added new function silc_server_remove_clients_by_server to
2553 remove all client entries from ID list when the server connection
2554 is lost. In this case it is also important to invalidate all
2555 client entires as they hold the invalid server entry. This
2556 fixes fatal bug when server has lost connection and will reconnect
2559 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2561 * Made some sanity checks to silc_server_daemonise like to check
2562 whether the requested user and group actually exists.
2564 * Added sanity check to SKE's silc_ske_responder_finish to check
2565 that the public and private key actually is valid.
2567 * Invalidate the client's nickname when receiving Replace ID
2568 packet and the Client ID is being replaced. This means that the
2569 server will query the nickname if someone needs it (client)
2572 * Sort the ID Cache in client library when the ID Cache data
2573 has changed (needs sorting).
2575 * Do not allow for SILC client to create several connections to
2576 several servers. The client does not support windows right now
2577 and generating multiple connections causes weird behaviour.
2579 Irssi-silc client does support windows and can handle several
2580 connections without problems, see: www.irssi.org and SILC plugin.
2582 * Fixed some places where client was added to the IDList. The
2583 rule of thumb is following (in order to get everything right):
2584 If the client is directly connected local client then the
2585 `connection' argument must be set and `router' argument must be
2586 NULL to silc_idlist_add_client function. If the client is not
2587 directly connected client then the `router' argument must
2588 bet set and the `connection' argument must be NULL to the
2589 silc_idlist_add_client function.
2591 * The funtion silc_server_packet_send_local_channel actually did
2592 not check whether the client was locally connected or not. It
2593 does that now. Fixed a bug related to LEAVE command.
2595 * Fixed Remove Channel User payload parsing bug in server's
2596 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2598 * The server's silc_server_save_channel_key now checks also the
2599 global ID list for the channel as it might not be in the local
2600 list. Fixed a bug related to LEAVE command.
2602 * Is this the end of the [<unknown>] buglet that has been lurking
2603 around for a long time? A little for loop fix in server's
2604 silc_server_command_whois_parse that is used by both IDENTIFY
2605 and WHOIS command. At least, this was a clear bug and a cause
2606 of one type of [<unknown>] buglet.
2608 * WHOIS and IDENTIFY commands call the function
2609 silc_server_command_[whois/identify]_check function even if
2610 we are not router server.
2612 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2614 * Added --with-gmp configuration option. If set the GMP
2615 is always compiled in the SILC source tree. If not set then
2616 it is checked whether the system has the GMP3 installed. If
2617 it has then the GMP won't be compiled (the system's headers
2618 and library is used), if it doesn't have it then the GMP is
2619 compiled in the SILC source tree.
2621 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Changed RSA private exponent generation to what PKCS #1
2624 suggests. We try to find the smallest possible d by doing
2625 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2626 not security fix but optimization.
2628 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2630 * Added new config entry [Identity] to fork the server and run
2631 it as specific user and group. A patch from Bostik.
2633 * Imported Dotconf configuration library into lib/dotconf.
2634 This will be used to create the SILC configuration files later.
2635 It will appear in the distsribution after this commit.
2637 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * A big code auditing weekend happening. Auditing code for
2640 obvious mistakes, bugs and errors. Also, removing any code
2643 Removed files for being obsolete:
2645 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2646 inline in the file lib/silcutil/silcbuffer.h)
2648 o lib/silcutil/silcbufutil.c (the header has inline versions)
2650 Changed code to fix possible error conditions:
2652 o The buffer formatting routines now check that the destination
2653 buffer really has enough space to add the data. This applies for
2654 both buffer formatting and unformatting
2655 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2656 unformatting was changed to accomodate following rules:
2657 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2658 sent to the function while XXX_*STRING will not allocate or copy
2659 the data into the buffer. Instead it sets the pointer from the
2660 buffer into the pointer sent as argument (XXX_*STRING used to
2661 require that the pointer must be allocated already). This change
2662 makes this whole thing a bit more consistent and more optimized
2663 (note that the data returned in the unformatting with XXX_*STRING
2664 must not be freed now). The routines return now -1 on error.
2666 o Tried to find all code that use buffer_format and buffer_unformat
2667 and added return value checking to prevent formatting and
2668 especially unformatting errors and possible subsequent fatal
2671 o Changed ske->x and ske->KEY to mallocated pointers in
2672 lib/silcske/silcske.h. Fixed possible data and memory leak.
2674 o Added return value checking to all *_parse* functions. Fixed
2675 many memory leaks as well.
2677 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2678 so that buffer overflows would not happen. All code now also
2679 checks the return value as it can fail.
2681 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Added reconnection support to server if the normal server looses
2684 its connection to the router (for example if router is rebooted).
2685 The server performs normal reconnection strategy implemented
2686 to the server. Affected file silcd/server.c.
2688 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2690 * Added new packet type SILC_PACKET_SET_MODE that is used to
2691 distribute the information about changed modes (for clients,
2692 channels and clients channel modes) to all routers in the
2693 network. Updated the protocol specification accordingly.
2695 Added functions into silcd/packet_send.c and
2696 silcd/packet_receive.c: silc_server_send_set_mode,
2697 silc_server_set_mode.
2699 Added new files silcmode.[ch] into lib/silccore that implements
2700 the encoding and decoding of Set Mode Payload. Added new type
2701 SilcSetModePayload. Moved the definitions of different modes
2702 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2704 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2706 * Oops, a little mistake in server's connection authentication
2707 protocol. The protocol is not ended with FAILURE but with
2708 SUCCESS if the authentication is Ok. :) Affected file is
2711 * Implemented NICK_CHANGE notify handling in server in the file
2712 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2713 the local clients on the channel. After the changing nickname
2714 in router environment snhould work and the [<unknown>] nickname
2715 should appear no more.
2717 The silc_server_replace_id function that receives the Replace ID
2718 payload now sends the NICK_CHANGE notify type also in the file
2719 silcd/packet_receive.c
2721 * Changed WHOIS and IDENTIFY command to support the maximum amount
2722 of arguments defined in protocol specs (3328 arguments). This
2723 fixed a bug that caused problems when there were more than three
2726 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Added extra parameter, command identifier, to the
2729 silc_client_send_command so that explicit command identifier
2732 Changed that ID list routines uses specific command identifier
2733 when sending WHOIS/IDENTIFY requests to the server so that they
2734 can be identified when the reply comes back.
2736 Affected files lib/silcclient/command.[ch],
2737 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2739 * Added `sender' argument to silc_server_packet_send_to_channel
2740 to indicaet the sender who originally sent the packet to us
2741 that we are now re-sending. Ignored if NULL. Affected file
2742 silcd/packet_send.[ch].
2744 * Added some server statistics support in silcd/server_internal.h
2745 SilcServerStatistics structure and around the server code. Also
2746 send some nice statistics information when client is connecting
2749 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2751 * Fixed channel ID decoding in server's JOIN command reply in
2752 silcd/command_reply.c
2754 * Fixed braodcasting of replace ID payload to not to send it if
2755 we are standalone server in silcd/packet_receive.c.
2757 * Fixed all channel message sending routines to not to send
2758 packets to clients that has router set, since they are routed
2759 separately in the same function earlier. Affects file
2760 silcd/packet_send.c and all channel packet sending functions.
2762 * In USERS reply, res_argv[i] are not allocated, the table
2763 is allocated. Thus changed that free the table, not its
2766 * In server's whois_check and identify_check if the client is
2767 locally connected do not send any WHOIS commands - they are not
2770 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Fixed some minor bugs in client when sending WHOIS command. The
2773 arguments was in wrong order.
2775 * Removed statis function add_to_channel from server in
2776 silcd/command.c that was previously used with the joining but
2779 * Tested USERS command in router environment successfully with two
2780 routers, two servers and two clients.
2782 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2784 * Reorganized the USERS command and command reply in client library
2785 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2786 When the command is given by user we register a pending command
2787 callback that will reprocess the command after the reply has been
2788 received from the server. When reprocessing the packet we then
2789 display the information. Thus, the USERS information is displayed
2790 now in the command callback instead of in the command reply
2791 callback. The processing of the command is same as previously
2792 when server has sent the command reply in the JOINing process.
2794 * Added to USERS command in silcd/command_reply.c to join the client,
2795 we didn't use to know about, to the channel after we've created
2796 a client entry for it. Also, for clienet we did know already still
2797 check whether it is on the channel or not and add it if not.
2799 * Removed silc_server_command_join_notify as the function and its
2802 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2804 * Changed the client's pending command handling to the same as the
2805 server's pending command handling. It is also now possible to
2806 execute command reply functions from other command reply
2807 function as the function callbacks for commands and command
2808 replies are one and same. The pending commands are not static
2809 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2810 in client connection context. Thus, pending commands are server
2811 connection specific as it is convenient.
2813 Changed the function silc_client_command_pending and
2814 silc_client_command_pending_del and added new function
2815 silc_client_command_pending_check. Removed the
2816 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2819 * Added cmd_ident, current command identifier, to the client
2820 connection context in lib/silcclient/client.h to keep track on
2821 command identifiers used in command sending. Client's command reply
2822 function handling now supports the mandatory command identifiers.
2824 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2825 funtions in client to fully support pending command callbacks.
2827 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2828 as one of the arguments to the application in the command reply
2831 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2832 before first releasing SILC but came back. Now it is removed again
2833 and should come back nomore. The FORWARDED flag was used only
2834 by the JOINing procedure by forwarding the command packet to router.
2835 Now, the JOINing procedure has been changed to more generic (due
2836 to various router environment issues) and FORWARDED is not needed
2837 anymore for anything. The protocol specification is yet to be
2840 Now, removed silc_server_packet_forward from server and the flag
2841 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2843 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2845 * Renamed NAMES command to USERS command. The NAMES was named that
2846 due to historical reasons. Now it is renamed. Also, rewrote
2847 parts of the USERS command. The nickname list is not sent anymore
2848 by the server. Only Client ID and mode lists are sent in the USERS
2849 command. Changed this also to the protocol specification.
2851 The client now resolves the names and stuff after it receives
2852 the USERS list from the server when joining to the channel.
2854 * WHOIS and IDENTIFY commands has been changed to support multiple
2855 Client ID's per command. One can now search for multiple users
2856 in the network by sending only one WHOIS or IDENTIFY command.
2857 Changed the code and the protocol specifications.
2859 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2860 uses silc_server_command_whois_parse to parse the request. */
2862 * If normal server, do not parse the WHOIS and IDENTIFY requests
2863 before sending it to the router. Saves some time.
2865 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Fixed JOIN command on client library. Wrong number of arguments
2868 used to crash the client.
2870 * Added silc_server_channel_has_global function to check whether
2871 channel has global users or not.
2873 * Added silc_server_channel_has_local function to check whether channel
2874 has locally connected clients on the channel.
2876 * The silc_server_remove_from_one_channel now checks whether the
2877 channel has global users or not after given client was removed from
2878 the channel. It also checks whether the channel has local clients
2879 on the channel anymore. If it does not have then the channel entry
2880 is removed as it is not needed anymore.
2882 * The silc_server_notify now checks on JOIN notify whether the joining
2883 client is one of locally connected or global. If it is global then
2884 the channel has now global users on the channel and that is marked
2885 to the channel entry. Also, it now saves the global client to
2886 global list who is joining and JOINs it to the channel. This is
2887 for normal server, that is.
2889 Changed silc_server_send_notify_on_channel,
2890 silc_server_packet_relay_to_channel and
2891 silc_server_packet_send_to_channel check if we are normal server
2892 and client has router set (ie. global client) do not send the
2893 message to that client, as it is already routed to our router.
2895 * Implemented LEAVE notify type handling in silc_server_notify
2898 * Tested LEAVE command in router environment successfully. Tested
2899 with two routers, two servers and two clients.
2903 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2905 * Implemented SIGNOFF notify type handling in silc_server_notify
2908 * silc_server_remove_id now removes the client entry from all channels
2909 it has joined and thusly sends SIGNOFF notify type.
2911 * Rewrote the NAMES list generation in server by removing two excess
2912 loops. The lists are created now inside one loop.
2914 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * silc_server_remove_channel_user checks now also global list
2917 for channel and client.
2919 * silc_server_new_channel_user checks now both local and global
2920 list for channel and client. Fixed a bug in client id decoding.
2921 Used to decode wrong buffer.
2923 * silc_server_channel_message checks now both local and global
2924 list for channel entry.
2926 * Tested channel joining (hence JOIN) in router environment
2927 successfully. Tested with two routers, two servers and two
2930 * Tested channel message sending in router environment successfully.
2932 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2934 * Added silc_server_save_channel_key into server.[ch] to save the
2935 received channel key in Channel Key payload processing. It is
2936 also used in JOIN command reply handling.
2938 Equivalent function silc_client_save_channel_key added into
2939 client.[ch] into client library.
2941 * Changed JOIN command reply to send information whether the channel
2942 was created or not (is existing already) and the channel key
2943 payload. Changed protocol specs accordingly.
2945 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2946 the request was sent by ID and not by nickname. Crashed on
2949 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2952 now correctly save the received data.
2954 * silc_server_free_sock_user_data now notifies routers in the
2955 network about entities leaving the network.
2957 At the same time implemented functions silc_server_remove_id
2958 and silc_server_send_remove_id to receive and send REMOVE_ID
2959 packets. The packet is used to notify routers in the network
2960 about leaving entities. The ID removed will become invalid in
2963 * Added function silc_idlist_del_server into server. Removes and
2964 free's server entry from ID list.
2966 * silc_server_private_message function now checks, if we are router,
2967 that the destination ID really is valid ID, naturally.
2969 * In router when NEW_ID packet is received (for new client) the
2970 hash of the Client ID is saved in the ID Cache but the
2971 client->nickname is set to NULL, instead of putting the hash
2974 IDENTIFY command now also checks that client->nickname must be
2975 valid. If it is not if will request the data from the server who
2976 owns the client. Added new function
2977 silc_server_command_identify_check.
2979 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2980 to set the command to already allocated Command Payload.
2982 * Tested private message sending in router environment with two
2983 routers, two servers and two clients. Fixed minor bugs and now
2986 * Fixed segfault from client's NAMES command. Used to crash if
2989 * Forwarded packets must not be routed even if it is not destined
2990 to the receiver. Changed server code comply with this.
2992 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * Added `require_reverse_mapping' boolean value to ServerParams
2995 structure. If TRUE (not default) the server will require that
2996 the connecting host has fully qualified domain name.
2998 If the reverse mapping is not required and hostname could not be
2999 found the IP address is used as hostname.
3001 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3003 * Implemented version string checking to both client and server.
3004 The check is incomplete currently due to the abnormal version
3005 strings used in development version of SILC.
3007 * Changed all command functions in server to use the new
3010 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Changed char *data to unsigned char *data in ID Cache system to
3013 support binary data as ID Cache data. Changed code to support
3014 binary data in lib/silccore/idcache.c.
3016 * Renamed silc_server_packet_relay_command_reply to
3017 silc_server_command_reply as it is normal packet receiving
3018 function. Rewrote the function to accept command replys for
3019 servers and not only for clients.
3021 * Mark remote router always as registered server if we are connecting
3022 to it. Otherwise, commands sent by the router to us are ignored.
3024 * All ID List find routines now returns the ID Cache Entry pointer
3025 as well if requested.
3027 * WHOIS command works now in router environment, tested with two
3028 routers, two servers and two clients.
3030 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3031 in router environment (as it is almost equivalent to WHOIS) but
3032 hasn't been tested thoroughly. Added new functions:
3034 silc_server_command_identify_parse
3035 silc_server_command_identify_send_reply
3036 silc_server_command_identify_from_client
3037 silc_server_command_identify_from_server
3039 * Disabled route cache adding because adding two different ID's with
3040 same IP replaces the old cache entry thus giving wrong route.
3041 The entry->router->connection is always the fastest route anyway
3042 so route cache may not be needed. Of course, new routes maybe
3043 established after receiving the ID when the entry->router->connection
3044 might not be anymore the most optimal.
3046 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Add route cache for received ID for fast routing.
3050 * Added silc_server_packet_route to route received packet on router
3051 that is not destined to us.
3053 * Renamed silc_server_get_route to silc_server_route_get.
3055 * Added id_string and id_string_len fields into SilcServer to
3056 include encoded ServerID for fast comparing without excess
3057 encoding of the ID's.
3059 * Cleaned up WHOIS command on server side. Added following static
3062 silc_server_command_whois_parse
3063 silc_server_command_whois_check
3064 silc_server_command_whois_send_reply
3065 silc_server_command_whois_from_client
3066 silc_server_command_whois_from_server
3068 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3069 arguments in command replies. All command functions should be
3070 updated to use this macro.
3072 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Minor typo fixes on command reply handling on server.
3076 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3078 * Added silc_server_command_add_to_channel internal routine to add
3079 the client to the channel after router has created the channel and
3080 sent command reply to the server.
3082 * Added generic silc_server_send_command to send any command from
3085 * Use static buffer with ID rendering instead of duplicating data.
3087 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3089 * Fixed a channel user mode bug when joining to a channel server gave
3090 everybody channel founder rights, oops.
3092 * We mark ourselves as the router of the incoming server connection
3093 if we are router ourselves. This way we can check in some packet
3094 sending functions whether it is locally connected server. For
3095 incoming router connections we put NULL.
3097 * For router sending packets locally means now always sending the
3098 packet cell wide; to local clients and local servers. For normal
3099 server sending packet locally means sending it to only local
3102 * Fixed the JOIN command to really work in router environment. If the
3103 channel is created it is always created by the router. Router is
3104 also responsible of making the initial joining to the channel,
3105 sending JOIN notify to the sending server and distributing
3106 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3107 does not exist server doesn't do anything else but forward the
3108 command to the router which performs everything.
3110 * Added silc_server_send_channel_key function to send the Channel Key
3113 * Added silc_server_create_channel_key to create new channel key. The
3114 channel key is now re-generated everytime someone joins or leaves
3115 a channel, as protocol dictates. Note: channel->key_len is the
3118 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3121 packet_receive.[ch] to separate packet sending and receiving
3122 routines. The server.[ch] now includes everything else including
3123 actual packet processing (writing and reading data) and other
3126 Renamed silc_server_private_message_send_internal to
3127 silc_server_send_private_message. The routine is still though
3128 used only to relay private messages as server does not send
3129 private messages itself.
3131 Renamed silc_server_new_channel to silc_server_create_new_channel
3132 and added new function sicl_server_new_channel that handles the
3133 incoming New Channel packet. Added also new sending function
3134 silc_server_send_new_channel to send New Channel Payload.
3136 * Added new function silc_server_notify to process incoming notify
3137 packet to the server/router. Server may then relay the notify
3138 to clients if needed.
3140 * Added new function silc_server_new_channel_user to process incoming
3141 New Channel User packet. Router will redistribute the packet and
3142 send JOIN notify to its local clients and locally connected servers
3143 if needed. Normal server will send JOIN notify to its local client
3144 on same channel when received this packet. Added also corresponding
3145 sending function silc_server_send_new_channel_user to sent the
3148 * Added boolean route argument to send_notif_to_channel and
3149 packet_send_to_channel functions to attempt to route the packet
3150 if it is TRUE and send only locally if it is FALSE.
3152 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3154 * silc_server_replace_id now broadcasts the received replace ID
3155 packet if it is not broadcast packet already. The router must
3156 broadcast to inform other routers about changed ID.
3158 * Added backpointer to server's router into SilcServer context in
3159 silcd/server_internal.h.
3161 * Fixed silc_server_packet_broadcast to send correct broadcast
3164 * The channel key is now distributed to the local client as soon
3165 as it is received from the router (in router environment) so that
3166 no other packet may be sent for the channel until client has
3169 * silc_server_remove_channel_user now broadcasts the received
3170 Remove Channel User packet if it is not broadcast packet already.
3171 The router must broadcast to inform other routers about removed
3174 * Added users field into SilcPacketContext that is a reference count
3175 of the context. One can increase the reference count by calling
3176 silc_packet_context_dup which is now changed to just increase the
3177 reference count instead of duplicating the data. The reference
3178 count is decresed by calling silc_packet_context_free that will
3179 free the data after the reference count hits zero.
3181 For now on the packet context and everything allocated into it
3182 (including the raw packet from network) must be freed by calling
3183 the new silc_packet_context_free function. Added also new function
3184 silc_packet_context_alloc that must be used now to allocate the
3185 context. This also means that if a routine is asynchronous from
3186 silc_[client/server]_packet_parse_type the packet context must
3187 be duplicated by calling silc_packet_context_dup. Otherwise it
3188 gets free'd after silc_[client/server]_packet_parse_type returns.
3189 Also, one must remember that if packet is duplicated then its
3190 reference count must be decresed by calling the free function as
3191 many times as it was duplicated.
3193 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3194 from both client and server.
3196 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3198 * Made joining to a channel working in router environment.
3200 * Cleaned up JOIN command on server side and create function
3201 silc_server_command_join_channel internal routine to make the
3204 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Changed silc_command_pending list to SilcDList. Also, added
3207 `ident' field to SilcServerCommandPending structure to identify
3208 the reply and to call correct callback.
3210 Added silc_server_command_pending_check function to replace the
3211 corresnponding macro. The silc_command_pending list is not
3214 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3215 to set identifier to previously allocated Command Payload. It
3216 is used to set identifier for command when resending Command
3219 * Added silc_command_payload_encode_payload to encode Command
3220 Payload buffer from SilcCommandPayload structure.
3222 * Added silc_argument_payload_encode_payload to encode Argument
3223 payload buffer from SilcArgumentPayload structure.
3225 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Changed WHOIS command to support router connection on server side.
3228 The whois request is always sent to router unless the server is
3229 standalone server. After server has received the reply from the
3230 router will it send the reply to the client.
3232 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3233 broadcast received broadcast packet. The function is used only
3234 by router. The broadcast packet is always sent to the router's
3237 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3238 render given ID to printable string, for log files for example.
3240 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Made basic router to router connections working. At least they
3243 can now connect to each other but nothing really works the way
3244 they are supposed - yet.
3246 * Added new initiator token to RouterConnection configuration
3247 file in silcd/serverconfig.[ch]. It is used to tell whether we
3248 are the initiator to the remote router or whether we'll expect
3249 the other end to connect.
3251 * Moved registering of listener task to silc_server_init, hence
3252 the server starts listenning as soon as it is run, even if it
3253 does not have connections to other routers. Let's see how well
3256 * Changed default connection retry timeouts for more suitable in
3259 * Removed cipher and such arguments from silc_idlist_add_client
3260 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3261 Added new function silc_idlist_add_data to add the keys and stuff
3264 * Added SilcIDListData structure and added it to SilcClientEntry
3265 and SilcServerEntry as their first field in the structure. This
3266 way we can explicitly cast the ID entries to the SilcIDListData
3267 structure and get common data for the entries. In past, we had
3268 to first check what type of connection it is and then cast it to
3269 correct ID entry type. Now, we can directly cast the opaque
3270 pointer to the SilcIDListData (no matter what ID entry it actually
3271 is) and get the data needed.
3273 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3276 in some circumstances even if threre were timeout tasks, though not
3277 IO tasks, but tasks anyway. Now fixed.
3279 * Defined SilcServerConnection structure to hold connection specific
3280 stuff about directly connected servers and routers. The definition
3281 is currently in silcd/server_internal.h. I thought about having
3282 a bit more important role fro this struct but for now it is used
3283 only when connecting to other server (or router actually).
3285 * Added connecting retry support in server when connecting to
3286 router(s). The retry feature implement exponential backoff
3287 algorithm. Also, added SilcServerParams structure to hold default
3288 parameters for server. For now, it include these retry settings
3289 and are hard coded. After server is moded to be as Silc Server
3290 Library this structure will be more important.
3292 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Changed client librarys channel->clients table to SilcList and
3295 changed code accordingly.
3297 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Changed client's channel table to SilcList and changed code
3300 accordingly. Also changed SilcChannelClientEntry to include back-
3301 pointer to the channel so that client entry can use that structure
3302 as list as well and we have fast cross-reference to the channel.
3303 This change dramatically decreased the complexity of channel
3304 handling with client entry and vice versa (removed one extra
3305 loop when searching for channel entry from many functions).
3307 * Changed server->sim from table to SilcDList and changed code
3310 * NAMES command can now be used from user interface. It will show
3311 the user list on the channel, neatly.
3313 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3314 Code now saves realname of the user if it becomes available.
3316 * Renamed configure.in to configure.in.pre and made ./prepare
3317 script to automatically add correct version string to
3318 configure.in which it creates from configure.in.pre.
3320 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * NAMES command reply now shows users mode with the nickname when
3325 * Moved silc_client_ch[u]mode[_char] functions from
3326 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3327 place sucks, they are utility functions and should be in some
3330 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3332 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3335 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3339 * Added TRQ (efficient deque and list library) into lib/trq. This is
3340 a very good list library that is currently used in the SILC. Defined
3341 SilcList API over the library because I didn't like the API very
3342 much. See lib/trq/silclist.h for the API and examples of how to
3343 use the API. Fixed various places in the code to use the new
3344 SilcList API. The SilcList is meant for lists that has a structure
3345 already defined as a list. It is not suitable to add just some
3346 context to the list (in TRQ, the context is the list actually).
3348 So, I defined SilcDList that can be used for the purpose where
3349 predefined list structure does not exit. This can be used as
3350 such list. Now some context just can be added to the SilcDList.
3351 Currently this list is not used in the SILC just yet, though there
3352 are a lot places where this can replace dynamically allocated
3353 tables and I will fix these places, later, to use SilcDList.
3354 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3355 and use TRQ internally).
3357 Also fixed some annoying warning messages that the original TRQ
3358 code generated. Also minor changes to TRQ's Makefile.in.
3360 * Added support for querying by Client ID to both WHOIS and
3361 IDENTIFY commands into server, as required by the protocol.
3363 * Removed method function pointers from SilcBuffer structure. They
3364 weren't used to anything and just increased the context size for
3365 no good reason. This change also made silc_buffer_alloc and
3366 silc_buffer_free functions inline functions.
3368 * Disabled command flooding detection support until it's fixed so
3369 that it accepts commands in but does not execute them more than once
3372 * Added silc_net_localhost(), to return local hostname, into
3373 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3374 that must be initialized before calling silc_client_init.
3376 * Added new function: silc_server_send_notify_on_channels to send
3377 notify messages to all channels client has joined. It is assured
3378 that the message is sent only once per client.
3380 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3381 lib/silcutil/silcutil.[ch] as silc_format function. The new
3382 function is generic and is used by server as well, not only by
3383 the logging routines.
3385 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3386 the provided version string was not acceptable. Added new function:
3387 silc_ske_check_version into lib/silcske/silcske.h. The function
3388 must be implemented by the application (client or server) and it
3389 does not reside in the SKE library. The function checks the version
3390 string remote end sent.
3392 * Added back pointers (to opaque context and to SilcSocketConnection)
3393 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3395 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3396 duplicate packet context structure.
3398 * Changed `notify' client operation to send same arguments as client
3399 receives from server except for ID's. ID's are mapped to correct
3400 ID entry and that is returned. Also, if channel entry is not sent
3401 by server but the notify is for channel the channel entry is sent
3402 to application (otherwise application doesn't know that it is for
3403 channel (library gets it from packet's Destination ID)).
3405 * Added silc_client_remove_from_channels into client library to
3406 remove a client from all channels it has joined to. Used when
3407 received SIGNOFF notify from server. Added also new function
3408 silc_client_replace_from_channels to replace old ID entry with
3409 new ID entry on all channels. Used when received NICK_CHANGE
3412 * Fixed ID Cache list handling in silc_idlist_get_client in
3413 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3414 to get (or query) client by ID.
3416 * Updated TODO list.
3418 * Added connection authentication status message defined by the
3419 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3420 support for these into the code in client and server side.
3422 * Added generic function silc_client_send_command to send any command
3423 with variable argument list. Application should use this function
3424 to send commands if the command functions provided by the library
3425 does not suite for the application's user interface needs.
3427 * Added new `failure' client operation. Application is notified about
3428 received failure packet if client is executing a protocol. In this
3429 case the protocol's execution has failed.
3431 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3432 is required by the protocol.
3434 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3435 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3438 * Added status flag to SilcSKE object to indicate realtime status
3439 of the SKE protocol.
3441 * Application receives now exactly same command reply arguments as
3442 the library receives from server. However, if ID is received the
3443 corresponding ID entry is returned to the application (eg. Client
3444 ID is mapped to correct SilcClientEntry entry and that is returned).
3445 Changed command_reply client operation due to this change.
3447 * Changed all ID's in commands and in command replys as ID Payloads.
3448 Change affected both client and server side codes.
3450 All ID's sent in SILC network (with execption of ID's in SILC
3451 Packet header) are sent in ID Payload to support variable length
3454 * Server now notifies nick changes and notifies all clients on
3455 the channels about the new nickname (about the new Client ID,
3458 * Implemented CMODE command to change channel modes. Supports all
3459 channel modes defined by the protocol specs except ban and invite
3460 lists. (Also, private channel key mode is supported but support for
3461 setting private channel key in client is missing, thus, this mode
3462 has no effect on client side (except that server requires that the
3463 client uses private channel key and normal channel traffic does not
3466 Also, invite mode works per se, but INVITE command does not work
3467 yet correctly, so you can set channel as invite only channel but
3468 inviting clients to the channel does not work (it is yet to be
3469 thought what's the best way to do it).
3471 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3472 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3473 Implemented CUMODE command to change user's mode on the channel.
3474 Supports all modes defined by the protocol specs.
3476 * Added NAMES command reply to return users modes on the channel.
3478 * Removed unnecessary and slow ciphers from lib/silccrypt.
3480 * Set SO_KEEPALIVE option to connection sockets by default.
3482 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3484 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3485 redefined the Notify Payload into protocol specs.
3487 * Added silc_id_payload_parse_id to get ID directly from raw
3490 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3492 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3493 accept searching by Client ID as well.
3495 * Added support for LEAVE and SIGNOFF notify types in client library.
3497 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3498 to parse ID Payload from raw data.
3500 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Added flags parameter into silc_ske_assemble_security_properties
3503 function in lib/silcske/silcske.[ch].
3505 * Changed notify client operation to fit better for notify messages
3506 sent by server. The notify payload received from server is now
3507 passed to the application (after parsing it to SilcNotifyPayload).
3508 It is application's responsibility to retrieve the arguments
3509 from the payload and show the message the way it wants. The message
3510 sent by server is implementation specific.
3512 * Changed public keys to comply with the protocol specification.
3513 Old public keys are not supported anymore and are not compatible.
3515 * Removed nickname from Channel Payload as the latest draft removed
3516 it. The client must resolve the nickname from the NAMES command
3517 reply received when it joined the channel.
3519 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3521 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3523 * Fixed some errors in protocol specification drafts.
3525 * Created lib/silccore/silcnotify.c to implement Notify Payload
3526 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3527 generic payloads described by protocol specifications. The file
3528 includes implementations for ID Payload and Argument Payload.
3530 * Changed Command Payload implementation to use the new Argument
3531 Payload. Changed command_xxxx_payload to command_payload_xxxx
3532 to comply with SILC coding conventions.
3534 * Added suppport for Argument Payload handling in Notify Payload
3535 implementation as protocol requires it. Added the new support
3536 into server and client lib as well.
3538 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * Added support for multiple nicknames on same channel. [n] is
3541 added locally to the nickname if there are more than one same
3542 nicknames on the channel.
3544 * Server now sends all nicknames that matched WHOIS request.
3545 Client also shows the list received from server.
3547 * Added TOPIC command to client side. User can now set and show
3548 current topic on channel.
3550 * Added MOTD command to client and server. Also, server sends the
3551 motd when client connects to the server.
3553 * Changed version strings to comply ISO 8601.
3555 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Fixed protocol error handling in client library. It should now
3558 cope even if the SKE fails for some reason.
3560 * Made new protocol specification drafts for submitting to IETF.
3562 * Implemented TOPIC command to server in silcd/command.c.
3564 * Added two new notify types into lib/silccore/silcnotify.h:
3565 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3566 notify nickname change and topic setting/change on a channel.
3568 * API change of command_reply operation in client library. The
3569 application gets now the status type received from server as well.
3571 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3573 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3575 * Cras fixed and optimized the packet handling even further and
3576 it should work now. Minor change to the prototype of function
3577 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3579 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3581 * Added new function into lib/silcutil/silcschedule.[ch]:
3582 silc_schedule_with_fd to select() a specified fd. The function
3583 returns after timeout expires or data arrives or goes. The
3584 function is used by packet routines to wait that all data is
3585 received from network.
3587 * Fixed data reading from network in lib/silccore/silcpacket.c.
3588 The code now assures that all data is read from the fd and then
3589 continues packet processing. This was a bug fix since the code
3590 used to drop some data in some circumstances.
3592 * Added new function into lib/silcclient/client.[ch]:
3593 silc_client_start_key_exchange to start key exchange after
3594 connection has been established to server. The code internally
3595 now uses this funtion but its main purpose was to provide it
3596 for applications that perform their own connecting. After
3597 application has created a connection it merely calls this
3598 function to start the key exchange between client and server.
3599 The library takes care of everything else after that.
3601 Updated also lib/silcclient/README to explain the usage of
3604 * Do not send to application information that connection has
3605 been established. Application gets notified it by connect
3608 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Applied cras's patch to add silc_schedule_one function. The
3611 function runs scheduler once and returns.
3613 * Fixed the scheduler after cras messed it up. The timeout
3614 handling works now as it's supposed to work.
3616 * Added into lib/silccore/ silcnotify.h to include notify
3617 message types support. Changed silc_server_send_notify*
3618 functions, in server.[ch], to support those new notify types.
3619 Added the support for the notify types into client library,
3620 as well. Added new notify client operation into ops.h in
3623 * Changed silc_server_packet_send_to_channel to send normal
3624 packets instead of just channel message packets. The function
3625 is now used to send the notify packets to channels. It is not
3626 used to send channel message packets anymore, as server never
3629 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3630 va_arg()s as it seems to require it nowadays. I guess, if SILC
3631 is compiled with older va_arg() the new code should work anyway.
3633 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Splitted core library. Core library (lib/silccore) includes
3636 now only SILC protocol specific core (and common) components.
3637 Created new utility library (lib/silcutil) that includes more
3638 generic purpose stuff. The stuff for util library was taken
3639 from the old core library. This was minor and easy split.
3641 * Created SILC Client Library (lib/silcclient) that includes
3642 implementation of the SILC client without user interface. This
3643 was major move from silc/ directory. The code has been changed
3644 so that it is transparent towards the user interface. The
3645 silc/ directory includes now the same user interface as before
3646 and it uses the new client library. Read lib/silcclient/README.
3647 Basicly, the client library performs everything else related
3648 to SILC except user interface handling. Also, configuration
3649 files are considered to be part of user interface and library
3650 does not handle them.
3652 This change also changed a lot of structures, function naming etc.
3653 Most important change was that SilcClientWindow object was
3654 renamed to SilcClientConnection in the client library. Created
3655 also new file lib/silcclient/ops.h. Also added new files
3656 silc/local_command.[ch] and silc/client_ops.[ch].
3658 All these changes were made to make it easier for user interface
3659 designers to create what ever user interface for the SILC client
3662 It is also expected that the server will be moved to lib
3663 directory as well and SILC Server Library will be created;
3664 sometimes in the future.
3666 * Removed Local commands from lib/silccore/silccommand.h as
3667 they are application specific and new client library does not
3668 handle any of those anymore.
3670 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3671 old client implementation in silc/.
3673 * Added support for callback functions in SILC_LOG_* macros.
3674 Application can now set its own callbacks that will be called
3675 instead of using the default functions that will always print
3676 the debug messages to stderr (or stdout). Also, debugging can
3677 now be disabled by setting silc_debug to FALSE and re-enabled by
3678 setting it to TRUE. Note, that logging will still work even
3679 if debugging is disabled.
3681 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3682 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3683 silc_log_reset_debug_callbacks.
3685 * To enable debugging in silc client one must give now -d
3686 option on command line.
3688 * Changed silc_schedule_init to automatically allocate task queues
3689 if they are not allocated before calling it.
3691 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3693 * Added GMP 3.1 into math library.
3695 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3698 a channel in SILC network. The packet is used by servers and
3699 routers to notify other routers that user has left a channel.
3700 This little feature was missing until now. Added the feature
3701 to protocol specification as well.
3703 Added functions: silc_server_send_remove_channel_user and
3704 silc_server_remove_channel_user into server.[ch].
3706 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3707 lib/silccore/silcpacket.h. However, they are not implemented
3710 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3712 * Fixed joining to a channel and sending channel messages
3713 between server and router. The channel message sending should
3714 now work inside a cell.
3716 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Fixed the private message sending between server and router.
3719 The private message sending should now work inside a cell.
3721 * Added silc_server_replace_id into server.[ch] to replace
3722 existing ID in the SILC network.
3724 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3725 and silc_idlist_replace_server_id into idlist.[ch] in server.
3727 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3729 * Fixed the server to server connections. Server can again now
3730 connect to router. Router to router connections probably does
3733 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3735 * Added dynamic protocol registering support. Now protocols can
3736 registered and unregistered on the fly. Patch by cras.
3738 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Added lib/contrib directory to hold routines that some platforms
3741 don't have but are needed by SILC.
3743 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3744 into lin/contrib to provide getopt() and getopt_long() for
3745 those who don't have it.
3747 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Added AWAY command to client. When away message is set and
3750 client receives a private message packet the client automatically
3751 replies to the sender with the away message.
3753 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3754 bug seemed to be the cause of recent problems when compiling
3757 * Added version detection support to SKE protocol specification
3758 and added the new changes to the SKE implementation as well.
3759 There were other minor changes in the SKE protocol as well.
3761 Many changes in lib/silcske/silcske.[ch] and in
3762 lib/silcske/payload.[ch].
3764 * Added ^U functionality, clear input line. Patch from cras.
3766 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Mainly small bugfixes on core library. Fixed some debugging
3769 logging and buffer overflow in silclog.c.
3771 * Updated config.sub and config.guess on the distribution tree.
3773 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Added command lagging support in server. Client may execute
3776 commands now only once in two seconds.
3778 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Optimized packet reception. MAC computation and checking is now
3781 also more optimized. A lot previously duplicated code is now
3782 used as generic by both client and server.
3784 * Fixed key pair generation in clientutil.c
3786 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3788 * Added into lib/silccore/silcbufutil.[ch] new function;
3789 silc_buffer_realloc.
3791 * Moved generic packet sending/encryption functions to
3792 lib/silccore/silcpacket.[ch] from client and server. Some
3793 rewriting of the functions.
3795 * Moved all generic packet reception/decryption functions to
3796 lib/silccore/silcpacket.[ch] from client and server. The
3797 packet processing is now much cleaner in both client and server.
3798 These were major changes in both client and server.
3800 * Created many common functions in server to do packet sending.
3801 Previously code were duplicated a lot, this has been removed
3804 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3806 * Rewrote major parts of the ID cache system. Don't know
3807 whether it is better now or not but at least the API is more
3810 * Major rewrite on ID cache stuff on client because of the ID
3811 cache API changes. Added idlist.c to client.
3813 * Also major rewrite on ID cache stuff on server as well.
3814 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3815 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3816 in hand, instead they are all put into the ID cache system now.
3817 All server_idlist_* routines uses ID cache now instead of
3818 traversing its own lists (those lists does not exist anymore).
3819 SilcIDList though still exists. Also, SilcXXXEntry's are
3822 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Finally made the SKE implementation compliant to the protocol
3825 specification. All mp integers are now binary encoded as
3826 opposed being HEX encoded.
3828 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3831 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3832 functions: silc_[encode/decode]_pem. Also added function
3833 silc_encode_pem_file to PEM encode with newlines ('\n') for
3836 * SILC public keys are now encoded either PEM or binary. Same
3837 option is for private keys as well. By default private keys
3838 are binary encoded and public keys PEM encoded. Silly HEX
3839 encoding were removed.
3841 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3842 function to create fingerprints.
3844 * Fixed a bug in SHA1; does not change the original data anymore.
3846 * Partly implemented INFO command on client and server side.
3847 Fixed CLEAR command. Changes to SERVER command; show current
3848 server(s) when giving command without arguments. Added
3849 VERSION command to client.
3851 * Added check to server that unregistered connections cannot
3852 execute commands (unless it is specificly allowed).
3854 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Fixed screen refresh.
3858 * Fixed channel joining bug from client. On some circumstances
3859 client tried to join to a channel it had already joined.
3861 * Added public key verification process into client's protocol.c.
3862 The client now verifies the public key from user and saves
3863 it into ~./silc/serverkeys/ directory.
3865 Added into: clientutil.[ch]: silc_client_verify_server_key.
3867 * Changed SKE protocol's silc_ske_initiator_finish function
3868 to accept callback function that verifies the received public
3869 key. Removed old silc_ske_verify_public_key function.
3871 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3873 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3874 silc_pkcs_private_key[_data]_set.
3876 * Made the password and public authentication more cleaner in
3877 server's protocol.c.
3879 * Removed historic and obsolete protocol `channel_auth' from
3880 both client and server.
3882 * Removed wrong way of sending command status messages from
3883 server to client in server's command.c. The old way violated
3884 protocol specification.
3886 Changes to silccore/silccommand.[ch]: removed
3887 silc_command_encode_status_payload -> not needed anymore,
3888 changed silc_command_encode_payload_va to accept extra
3889 argument on variable argument list. The argument type must
3890 now be provided to the function. Also, added new function:
3891 silc_command_encode_reply_payload_va which is same as
3892 normal command_encode_payload_va except command status type
3893 is provided as extra argument.
3895 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3897 * Added ~./silc directory handling. The directory includes the
3898 public and private keys for the client.
3900 Added silc_client_check_silc_dir, silc_client_create_identifier
3901 and silc_client_load_keys.
3903 * Implemented SILC protocol compliant public key. Added public
3904 and private key saving to and loading from files.
3906 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3907 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3908 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3909 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3910 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3912 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3913 silc_pkcs_load_[public/private]_key.
3915 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Added silc_server_get_route (route.[ch]) to get connection
3918 data for the fastest route for given ID.
3920 * Implemented INVITE command on client and server. The command
3921 were re-defined in the SILC Protocol Specification and the
3922 implementation now complies with the specification.
3924 * Implemented PING command on client and server.
3926 * Implemented NAMES command on client and server. The server side
3927 supports currently only normal server not router server yet.

3930 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Implemented LEAVE command on client and server.
3934 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3935 again. This change was made to the protocol as well. Server
3936 should not violate the protocol specification anymore.
3938 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3941 was tested. SOCKS4 was not but should work anyway.
