3 * make install generates new server keys only if there is not
6 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
9 Added check that if the NOREPLY is set then we will not send
10 the away message. This avoids infinite loop of away messages
11 if both clients are away. The affected file is
12 lib/silcclient/client_prvmsg.c.
14 * Fixed client crash if /NICK was given without arguments.
15 Affected file lib/silcclient/command.c.
17 * Server does not send the invite list in INVITE command back
18 to the client if the list was not altered. Added this notion
19 to the protocol spec as well. Affected file silcd/command.c.
21 Fixed possible crash in INVITE command by checking the
22 value of silc_server_get_client_route command.
24 * Fixed the INVITE notify type handling. The arguments are now
25 taken in correct order and client does not crash. The affected
26 file is irssi/src/silc/core/silc-channels.c.
28 Removed the "Inviting xxx to channel" message from the
29 client library away and let the application handle it.
30 Affected file lib/silcclient/command.c. Added that message
31 to Irssi SILC client's message formats.
33 * Fixed CMODE command crash in client. It now checks the
34 amount of arguments correctly and does not crash. The affected
35 file is lib/silcclient/command.c.
37 * Do not create new channel automatically in silc_channels_join
38 but check whether the channel by that name already exists.
39 Affected file irssi/silc/core/silc-channels.c.
41 * Do not send the SERVER_SIGNOFF to router if the disconnected
42 entity was the router. Affected file silcd/server.c.
44 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
45 SILC client as it was missing from there.
47 Added the handling of the KICK notify to the Irssi SILC client
48 as it was missing. Added "you have been kicked" message to
49 Irssi SILC client's message modules formats.
51 Added the handing of the KILL notify to the Irssi SILC client
52 as it was missing. Added the kill message module formats
55 The affected file is irssi/src/silc/core/silc-channels.c.
57 * The router did not save the channel mode the server announced.
58 Affected file silcd/packet_receive.c.
60 * Fixed a possible crash in INFO command in server. If the
61 server did not provide the server info it crashed. Affected
64 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
66 * Fixed the GETKEY command in the server to check also the
67 global list. Otherwise the GETKEY would not work correctly
68 in normal SILC server. Affected file silcd/command.c.
70 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
72 * Fixed GETKEY crash, it crashed if the command did not succseed.
74 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
76 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
77 is now real and not just an macro interface to GMP.
79 Removed the entire GMP from the source tree and imported new
80 NSS MPI library instead. Reason for removing GMP is that it is
81 extremely large and compiles extremely slow. The NSS MPI
82 is only a few files and compiles in less than 10 seconds.
83 The speed is also about the same as GMP. The MPI is imported
86 If the system has GMP installed we will still use the GMP.
87 If it is not then the NSS MPI will be compiled.
89 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
91 * Merged a long nickname (127 characters long) crash bugfix from
92 Irssi CVS tree. Affected file irssi/src/core/misc.c.
94 * Merged a freed memory reference bugfix from Irssi CVS tree.
95 Affected file irssi/src/core/commands.c.
97 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
99 * Added the server's public key sving and verification to the
100 server when performing the SKE. This was missing and the
101 remote server's (or router's) public key was accepted without
102 checking whether we have it previously or trust it at all.
103 Affected file silcd/protocol.c.
105 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
107 * Check in the silc_server_timeout_remote if protocol is active
108 and make sure that the protocol's final callback is called so
109 that all memory if freed. Affected file silcd/server.c.
111 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
113 * silc_server_whois_send_reply crashed the server if the nickname
114 was 127 characters long. Affected file silcd/command.c.
116 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
118 * Added sanity check to the silc_server_new_client. If the hostname
119 is provided inside username then check that the provided hostname
120 really is the same as the resolved one. If the hostname was not
121 resolved then check it from the public key. Affected file is
122 silcd/packet_receive.c.
124 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
125 if the server disconnected us and the connection is not valid
126 anymore. Affected file irssi/src/silc/core/silc-channels.c.
128 * Moved the silc_client_[chmode|chumode|chumode_char] away from
129 the library to the lib/silcutil/silcutil.[ch].
131 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
133 * Close log file after open. Affected file
134 lib/silcutil/silclog.c.
136 * Check whether sock == NULL in silc_client_send_packet and return
137 if it is. Affected file lib/silcclient/silcclient.c.
139 * Check rec->entry == NULL in the Irssi SILC Client before
140 sending the channel message. Affecte file is
141 irssi/src/silc/core/silc-servers.c.
143 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
145 * Merged a splitted window bugfix from Irssi CVS tree. The
146 affected file is irssi/src/fe-text/textbuffer-view.c.
148 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
149 It did not print nickname.
151 * Improved the distributions system a bit.
153 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
155 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
156 irssi/src/fe-text/gui-window.c.
158 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
159 to in-active server. The affected file is
160 irssi/src/silc/core/client_ops.c.
162 * Resolve the client in USERS command reply if the entry does
163 not have username resolved. The affected file is
164 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
165 command to WHOIS command to really resolve stuff. The USERS
166 is not used any more in any critical section so WHOIS can
167 be used even though it might be slower than IDENTIFY.
169 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
172 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
174 * Changed the protocol API a bit more consistent in the
175 lib/silccore/silcprotocol.[ch].
177 * Changed the following headers to ROBODoc format:
179 lib/silccore/silcpayload.h
180 lib/silccore/silcprotocol.h
181 lib/silccore/silcsockconn.h
183 All core library headers are now formatted.
185 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
187 * Fixed a bug in Irssi SILC client; do not show that you are
188 server/router operator if you really are not. Affected file is
189 irssi/src/silc/core/client_ops.c.
191 * Renamed silc_command_free_payload to silc_command_payload_free.
192 Affected file lib/silccore/silccommand.h
194 * Added silcmath.h to include the prototoypes of various routines
195 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
198 * Changed the following headers to ROBODoc format:
200 lib/silccore/silcchannel.h
201 lib/silccore/silccommand.h
202 lib/silccore/silcid.h
203 lib/silccore/silcidcache.h
204 lib/silccore/silcmode.h
205 lib/silccore/silcnotify.h
206 lib/silccore/silcpacket.h
207 lib/silcmath/silcmath.h
209 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
211 * Added checking to the server code not to start the server if
212 ciphers and stuff are not configured properly. Affected files
213 silcd/serverconfig.[h] and silcd/server.c.
215 * Changed the layout of the header files of the public interfaces
216 in the SILC libraries. The new layout supports ROBODoc
217 documentation tool (and some others) so that it is easy to create
218 a library reference manual. All the other headers and source
219 code must still follow the CodingStyle document. Also source
220 code must not include these ROBODoc stuffs, only the headers.
221 Furthermore, all public interface headers must now be named
222 by using `silc' prefix, example: silcapi.h, silccipher.h.
223 Some files were renamed due to this. All the other headers
224 must not be used as public interfaces. I will update the
225 CodingStyle document later. Changed following headers, so far:
227 lib/silcclient/silcapi.h
228 lib/silccore/silcauth.h
229 lib/silccore/silcprivate.h
230 lib/silccrypt/silcdh.h
232 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Removed silc_client_packet_send_flush from the client library
237 as it is not needed. Affected file lib/silcclient/client.[ch].
239 * Added printing of message of unresolved authentication method
240 to the Irssi SILC client. Added it to the module formats.
241 Removed the same message from the client library.
243 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
245 * Added new distribution feature, DISTLABEL. Every distribution
246 can define own preprocessor label that can be used in the
247 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
248 file distributions, acconfig.h.pre and prepare.
250 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
252 * Added Makefile.defines_int to include the actual definitions
253 for Makefile.defines.in. Tested the new distribution system,
254 created distributions and tested installation.
256 * Added AWAY message printing to the Irssi SILC client. Added
257 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
259 * Added SCONNECT command to call the SILC's CONNECT command.
260 Cannot use CONNECT directly since Irssi uses that internally.
261 Affected file irssi/src/silc/core/silc-servers.c.
263 Added ACTION local command. It is same as ME command but takes
264 the channel as mandatory argument.
266 Rewrote some of the Irssi's help files to suite for SILC
269 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
271 * Added Makefile.defines[.in] that should for now on be included
272 in all Makefile.am file in the source tree. That file includes
273 all common compilation definitions for SILC source tree.
275 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * Minor changes to the ./prepare script to change the package
278 name according the distribution name to the configure.in.
280 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
282 * Created new distribution system. Added file `distributions'
283 that defines all the distributions that can be created out of
284 the SILC source tree. The ./prepare script now reads that
285 file to determine how to prepare the distributions. The
286 first argument to the ./prepare is the name of the distribution
287 and second is the version of the distribution. If given
288 without arguments it creates the default (toolkit) distribution
289 with the default version (defined in ./prepare).
291 All Makefile.am files that are subject to the distributions
292 are now named as Makefile.am.pre. These are ./Makefile.am
293 and lib/Makefile.am. Others may be changed later.
295 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
297 * Added invite list, ban list, some key management and connection
298 error message printing to module formats in the Irssi SILC client.
300 * Added new silc_client_set_away_message to set the away message
301 that is back to the person who sent private message. The
302 affected file lib/silcclient/silcapi.h and the
303 lib/silcclient/client_prvmsg.c.
305 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
307 * Fixed the private message sending in the Irssi SILC client,
308 added local command KEY to the Irssi SILC client.
310 Added key management and key agreement message formats to the
311 irssi/src/fe-common/silc/module-formats.[ch].
313 Added USERS (alias WHO) printing, server/router operator
314 indication and LIST command printing to the module formats.
316 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * Fixed channel joining notify handling, cumode notify handling
319 from Irssi SILC client.
321 * Added SILC specific module-formats to the Irssi SILC client so
322 that SILC specific message hilighting, colors etc is possible.
323 Affected file irssi/src/fe-common/silc/module-formats.[ch].
325 Added channel mode, channel user mode, actions, notices,
326 whois and whowas printing to the the module-formats.c.
328 * Fixed a bug in channel deletion in the server. The channel
329 is not left to the cache even if the channel founder auth mode
330 is set when there are no users anymore on the channel. Affected
333 * The silc_net_localhost now resolves the entire hostname including
334 the domain name. Affected file lib/silcutil/silcnet.c.
336 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
338 * Changed the ask_passphrase client operation to be ascynchronous.
339 It has now a completion callback and a context that the
340 application must call after it has got the passphrase from
341 the user. Affected files lib/silcclient/silcapi.h,
342 lib/silcclient/protocol.c, lib/silcclient/command.c and
345 Added SilcAskPassphrase callback that the application calls
346 to deliver the passphrase to the library.
348 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
349 The public key verification and especially a certificate
350 verification is asynchronous procedure.
352 Added new SILC_SKE_STATUS_PENDING status to indicate the
353 request is pending and a callback will be called to finalize
356 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
357 indicate that remote end did not send its public key (or
358 certificate), even though we require it. Added check for this
359 condition in the SKE. This was a security bug, now fixed.
361 Defined new SilcSKEVerifyCbCompletion callback that is called
362 when the verification process is completed.
364 The affected files lib/silcske/silcske_status.h and
365 lib/silcske/silcske.[ch].
367 * Changed the verify_public_key client operation to be async
368 as well. Defined SilcVerifyPublicKey callback that is used to
369 indicate the success of the public key verification process.
371 Changed the server and client to use the new async client
374 * Changed the Irssi SILC client's internal scheduler to be called
375 twice as many times as it used to be. As a result the client
376 should be a bit faster now. Affected file is
377 irssi/src/silc/core/silc-core.c.
379 * Added support to Irssi SILC client of asynchronous public key
380 verification and passphrase inquiry. Affected file is
381 irssi/src/silc/core/silc-core.c.
383 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * Do not say "You have left channel %s" in client library.
386 Moved it to the application. Affected files are
387 lib/silcclient/command.c and silc/client_ops.c.
389 * Fixed silc_client_get_clients. Command context was not
390 duplicated and was freed memory in the callback. Affected
391 file lib/silcclient/idlist.c.
393 * Do not say "you are now talking..." on JOIN command in the
394 client library. The appliation must handle it.
396 * Do not say ".. changed topic to" in command reply in the
397 client libary. The application must handle it.
399 * Fixed TOPIC command sending in the client library.
401 * Fixed a memory leak in silc_client_command_free in the file
402 lib/silcclient/command.c.
404 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Imported a modified version of Irssi client to the source tree.
407 The Irssi will be used to create a new client called
408 Irssi SILC. Imported to irssi/.
410 Added silc_core_init_finish function to the Irssi. Affected
411 file irssi/configure.in.
413 A lot changes in the Makefile.ams around the irssi tree.
415 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
417 * Do not rehash if the new size is same as the old size of the
418 hash table, in the silc_hash_table_rehash*. The affected file
419 lib/silcutil/silchashtable.c.
421 * Replaced hash_table_del_by_context calls from the server
422 (when channel->user_list and client->channels) to the
423 hash_table_del as it is sufficient and faster.
425 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
427 * Added silc_hash_table_list, silc_hash_table_get and the
428 SilcHashTableList structure to provide an alternative way to
429 traverse the hash table. The affected files are
430 lib/silcutil/silchashtable.[ch].
432 * Changed the server's idlist routines to use the hash table
433 routines to optimize the code.
435 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
437 * Replaced the client entry's `channel' list and channel entry's
438 `user_list' list to hash tables for optimized lookup. Changed
439 the code to use the hash table interface around the code.
440 Affected file lib/silcd/idlist.[ch].
442 * Added `auto_rehash' boolean argument to the function
443 silc_hash_table_alloc to indicate whether the hash table should
444 auto-rehash when it thinks is appropriate time. It will
445 increase the hash table size if the there is twice as much
446 entries in the table than the size of the table, and will
447 decrease the size if there are twice as less entries than
448 the size of the table.
450 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
452 * Fixed silc_xxx_get_supported to not crash at some circumstances.
454 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * silc_idcache_purge_by_context deletes the entry now by context
457 as it is supposed to do. Affected file lib/silccore/idcache.c.
459 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
460 client is not anymore valid (WHOWAS givens the info) and not
461 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
463 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
465 * Removed the `data' and `data_len' arguments from the ID Cache
466 interfaces and added `name' argument. ID Cache does not handle
467 anymore the binary data only a names associated with given ID.
469 * When hashing a Client ID with silc_hash_id the entire ID is
470 not hashed anymore, instead only the hash of the Client ID is
471 hashed. This way we can access the Client ID from the cache
472 with Client ID but with the hash of the ID (which is a hash of
473 the nickname) as well without any difference in performance.
475 Added also silc_idcache_find_by_id_one_ext to do one on one
476 searching when we have the actual ID. Added also function
477 silc_hash_client_id_compare. The affected files are
478 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
480 * When hashing the name associated with a ID it is always done
481 in lowercase. This way we can access the cache without worrying
482 about case-sensitivity, even though, for example nicknames are
485 * Fixed a bug in server with channel message sending. It put
486 wrong ID type as destination ID. The affected file
489 * silc_idcache_del_by_context now deletes from all hash tables
490 by context. Affected file lib/silccore/idcache.c.
492 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
494 * Changed the client library to use the new ID Cache interface.
495 Changes around the source tree.
497 * Added silc_hash_table_rehash_ext to rehash with specific
498 hash function. Affected file lib/silcutil/silchashtable.[ch].
500 * Added silc_hash_string_compare to compare two strings in the
501 hash table. Affected file lib/silcutil/silcutil.[ch].
503 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
505 * Added new function silc_idcache_del_by_context into the
506 lib/silccore/idcache.[ch].
508 * Changed the server's ID list routines to use the new ID Cache
509 interface. Changes around the source tree.
511 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
513 * Added silc_hash_table_del[_by_context]_ext functions in to the
514 lib/silcutil/silchashtable.[ch].
516 Removed silc_hash_table_find_all* routines and added new
517 silc_hash_table_find_foreach to replace them.
519 Added silc_hash_table_replace_ext function as extended
520 replacing function. Separated the simple hash table interface
521 from the extended hash table interface in the file
522 lib/silcutil/silchashtable.h.
524 * Fixed minor bugs and changed it to use some of the new
525 hash table functions in lib/silccore/idcache.c
527 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
529 * Added new function silc_hash_table_find_all to return all keys
530 in the hash table by the specified key. As the hash table is
531 collision resistant it also makes it possible to have several
532 duplicate keys in the hash table. This function may be used to
533 find all of the keys from the hash.
535 Added user_context arguments to the SilcHashFunction,
536 SilcHashCompare and SilcHashDestructor to deliver user specified
539 Added new fuctions silc_hash_table_find[_all]_ext to do
540 extended lookup with specified hash and compare functions and
541 specified user contexts.
543 Added new function silc_hash_table_add_ext to add the key
544 with specified hash function and user context.
546 Added new function silc_hash_table_foreach to traverse all
547 entrys in the hash table. Added SilcHashForeach callback
550 Added new function silc_hash_table_del_by_context to delete
551 the entry only if the context associated with the key matches.
553 Affected files are lib/silcutil/silchashtable.[ch].
555 * Removed silc_hash_[server/client/channel]_id and added just
556 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
557 silc_hash_id_compare to compare two ID's using as the hash table
558 comparison function. Added also silc_hash_data to hash
559 binary data and silc_hash_data_compare to compare it.
561 * Removed silc_idlist_find_client_by_hash as it is not needed
562 anymore. Affected file silcd/idlist.[ch].
564 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
565 to use internally the SilcHashTable. The new ID Cache is a lot
566 faster than the old one. Some of the ID Cache interface was also
567 rewritten and obsolete and stupid functions were removed.
569 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * Added entry_count field to the SilcHashTable to keep the number
572 of the entries in the table. Implemented the function
573 silc_hash_table_rehash. Added new function
574 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
576 Fixed a minor bug in silc_hash_table_free.
578 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
579 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
580 into the lib/silcutil/silcutil.[ch].
582 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
584 * Implemented a collision resistant hash table into the
585 lib/silcutil/silchashtable[ch]. See the header and the source
586 for the SilcHashTable API.
588 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
590 * Merged dotconf version 1.0.2 into lib/dotconf.
592 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
594 * Do not compile anything in lib/silcsim/* if the SIM support
595 is not enabled. The tree should now compile without problems
598 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
600 * Compiled the SILC under cygwin. Compiled and tested briefly
601 without problems. More tests needed. The SIMs didn't compile
604 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
606 * Fixed possible crash in silc_get_username in the
607 lib/silcutil/silcutil.c.
609 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
611 * Fixed a va_arg in silc/client_ops.c.
613 * Oops, RC5 routines were named AES and caused some problems
614 when not using SIM's. Affected file lib/silccrypt/rc5.c.
616 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * Added new SilcIDIP structure into the lib/silccore/id.h and
619 replaced the old `ip' fields from all SILC ID's to that type.
620 This is a step towards IPv6 support.
622 The silc_id_get_len takes now the ID as an extra argument.
623 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
624 both IPv4 and IPv6 based ID's.
626 The affected files are lib/silccore/id.[ch] and other files
627 around the tree using these routines.
629 * Removed the ID length arguments in server from various
630 silc_server_send_notify_* routines -> they are not needed
633 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
635 * Fixed memory leak in silc_encode_pem_file in the file
636 lib/silcutil/silcutil.c.
638 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Check minor version as well in the SKE. Affected files are
641 silcd/protocol.c and lib/silcclient/protocol.c.
643 * Added --identifier option to the server so that an identifier
644 can be when creating the public key for the server. Affected
645 file is silcd/silcd.c.
647 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
648 lib/silccrypt/silcpkcs.c.
650 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
652 * Register default ciphers and stuff when using -C option with
653 the server. Affected file sildc/silcd.c.
655 * Put back the servers public key filename format, it is better
656 than the new one. For now, the client keys are saved with the
657 new filename format. The affected file silc/client_ops.c.
659 * Implemented the Cipher API for the rest of the ciphers that
660 did not implement it or implemented it the wrong way.
662 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
664 * Register default ciphers and stuff when using the -S option
665 in the client. Affected file silc/silc.c. Same also when
666 creating new key pair with -C option.
668 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
670 * Fixed the silc_verify_public_key client operation function to
671 save the public keys differently. The fingerprint is now
672 used as filename and not the hostname. This way also the
673 client keys are saved uniquely and not with hostnames. The
674 affected file is silc/client_ops.c.
676 * Trimmed the silc_hash_fingerprint function to remove extra
677 whitespaces from the end of the fingerprint. The affected
678 file is lib/silccrypt/silchash.c.
682 * Added silc_cipher_register_default function to register all
683 default ciphers. It can be used when configuration files
684 does not exist and the application does not want any specific
685 ciphers in any specific order.
687 The SilcDList is now used as silc_cipher_list dynamically
688 allocated cipher list. Removed the static list all together
689 and now all ciphers must be allocated to the dynamic list.
690 The silc_cipher_alloc routine was changed to check only the
693 All silc_cipher_* routines that used to return int returns
696 The affected files lib/silccrypt/silccrypt.[ch].
698 * The same thing was done to silc_hash_* as for silc_cipher_*
699 routines. Affected files lib/silccrypt/silchash.[ch].
701 * The same thing was done to silc_pkcs_* as for silc_cipher_*
702 routines. Affected files lib/silccrypt/silcpkcs.[ch].
703 Added also silc_pkcs_[un]register[_default] functions.
704 Removed the data_context from the PKCS API.
706 * Added silc_hmac_register_default function to register default
707 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
708 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
709 to unregister all hmacs at once.
711 * Register the default ciphers, hash functions, PKCSs and HMACs
712 if client's configuration file does not exist. The affected
715 * The client did not load the hash functions from the SIM
716 modules at all. Added support for this. Affected file is
719 * When decoding public key with silc_pkcs_public_key_decode, check
720 the supported algorithm only if PKCS are registered. Affected
721 file lib/silccrypt/silcpkcs.c. The same was done with the
722 silc_pkcs_private_key_decode.
724 * Fixed the SILC List routines to keep the list always in order.
725 It used to change the list's order when traversing the list but
726 not it preserves the order. Affected file lib/trq/silclist.h.
728 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Added the client library to use the SilcSocketConnection's
731 reference counter (by silc_socket_dup) to prevent the bug that
732 the socket object may be freed underneath async operation.
734 * The name resolv library checking fixes in the configure.in.pre.
737 * Created new version of the protocol drafts for future
738 development. The -03 drafts are the ones that will be changed
739 in the trunk now and the -02 will remain as they are.
741 * Send list of CUMODE notifys to the router when announcing
742 the channel users to the router. Affected file silcd/server.c.
743 If the router receiving channel founder CUMODE for a channel
744 that already has channel founder it will send CUMODE notify
745 to the sender to remove the channel founder rights from the
746 announced client. Affected file silcd/packet_receive.c.
748 * The CUMODE notify may now use Server ID as well as the entity
749 who changes the mode. Updated protocool specs.
751 * Updated INSTALL and README files.
753 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * New web pages in the http://silc.pspt.fi. The pages was
760 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
762 * Implemented the [DenyConnectin] config section in the server.
763 Added silc_server_config_denied_conn to check whether incoming
764 connection is denied. Affected file silcd/serverconfig.[ch].
766 * Do not check the ports when checking the incoming configuration
767 data if the port is 0, meaning any. Affected file is
768 silcd/serverconfig.c.
770 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
772 * Fixed buffer overflow in silc_string_compare in the file
773 lib/silcutil/silcutil.c.
775 * Fixed double free in silc_server_command_leave in the file
778 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
780 * Fixed the version checking in the server. Affected file is
783 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
785 * Fixed the configuration data fetching when accepting new
786 connections in the server. Affected file silcd/server.c.
788 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
790 * Added `sender_entry' argument to the function
791 silc_server_packet_relay_to_channel so that we can check
792 whether some destination actually belongs to the same route
793 the sender belongs (ie, we must not resend the packet to the
794 sender). Affected file silcd/packet_send.[ch].
796 * Added `servername' field to the SilcClientEntry in the server
797 to hold the name of the server where client is from. Affected
798 file is silcd/idlist.h.
800 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
802 * Moved the channel message encrypting in the router betwen
803 router connections from silc_server_channel_message to the
804 silc_server_packet_relay_to_channel since we want to check
805 whether we have anybody channel before encrypting anything.
806 Affected files silcd/packet_[receive/send].c.
808 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
810 * Fixed the [AdminConnection] server config section to support
811 multiple entries. Affected file silcd/serverconfig.c.
813 * Added support into the server to check the validity of the
814 incoming connection before executing any KE or authentication
817 * The connection configuration is now saved to the KE and
818 connection auth protocol contexts and not fetched anymore in
819 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
821 * The local hosts listenning address and port is also resolved
822 now when starting the server. We want to have the socket object
823 to include the real address and port for the listener. Added
824 new function silc_net_check_local_by_sock into the files
825 lib/silcutil/silcnet.[ch].
827 * Fixed a broadcast bug in server -> do not broadcast if we
830 * Fixed a routing bug. Do not route broadcast packets ever.
831 Broadcast packets must be processed always and not routed since
832 they may be destined to some other host than yourself and thus
833 would get routed without no good reason. Affected file is
836 * Added function silc_server_config_is_primary_route to check
837 whether primary router connection has been configured (a router
838 configuration that we are initiating). If there is not, we
839 will assume that there is only two routers in the SILC network
840 and we will use the incoming router connection as our primary
841 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
843 * Changed the order of the broadcasting. Broadcast _after_ the
844 packet has been processed not before. Affected file is
847 * Fixed a [ClientConnection] parsing bug. The port was never
848 parsed correctly thus resulting to port 0. Affected file
849 silcd/serverconfig.c.
851 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
852 argument and did not set the broadcast packet flag. Affected
853 file silcd/packet_send.c. Fixed same bug in the function
854 silc_server_send_notify as well.
856 * If we receive NEW_ID packet for our own ID in the server, ignore
859 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
863 * Removed the nickname from the Private Message Payload.
864 Updated the code and the protocol specs.
866 * Updated protocol specs for submitting to the IETF.
868 * Tweaked the Random Number Generator a bit. Affected file
869 lib/silccrypt/silcrng.c. Exported a new function
870 silc_rng_[global]_add_noise which can be used to add more
873 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
875 * Do not parse packets with different timeout when protocol
876 is active -> may cause problem with rekey. Affected file
879 * When server receives signoff notify it must not create
880 new channel key if the client is on any channels since the
881 sender of the signoff notify will create it.
883 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
885 * Added printing of error messages during SKE protocol from the
886 failure packet sent by server during SKE. Affected file
889 * Removed the client's failure_callback handling with timeout
890 and handle it immediately when received.
892 * The SKE library returned wrong type in SUCCESS and FAILURE
893 packets. They must be 32 bit MSB not 16 bit MSB.
895 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
897 * Ok, rewrote the logic of the re-key and now it seems to work.
898 I tested it on high traffic with frequent re-keys without
899 problems. Added hmac_receive (and renamed hmac to hmac_send)
900 in SilcClientConnection in lib/silcclient/client.h and
901 in SilcIDListData in silcd/idlist.h. Also, removed the
902 SilcPacketParserContext's cipher and hmac fields as they are
903 not needed anymore and actually caused some problems when
904 the ciphers and hmac's changed underneath the packet parser.
906 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
908 * If re-key protocol is active then process the incoming packets
909 synchronously since we must assure that icoming packets encrypted
910 with the old key is processed before the new keys is set to
911 use. This is true other packets than for REKEY packets.
912 Affected file silcd/server.c. The same was done to client library
913 as well, affected file lib/silcclient/client.c.
915 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
917 * Fixed bug in client and server to accept the force send if
918 the packet is send from silc_[server/client]_packet_process
919 function. Otherwise the packets are never delivered, oops.
921 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
923 * Disable force sending of packets when REKEY protocol is active.
924 We must assure that no packet is sent directly when rekey is
925 performed. All packets must be sent through packet queue.
926 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
927 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
928 function is silc_[server/client]_packet_send_real to check
931 * Replaced the SIM paths from example config files to
932 /usr/local/modules. Also, make install creates now
933 /usr/local/silc/logs directory to hold all the SILC server
936 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
938 * Made the configure.in.pre work on Solaris. Patch by salo.

941 CBC mode macros into lib/silccrypt/ciphers_def.h.
943 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Fixed the make install.
947 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
949 * When MAC computation fails the silc_packet_decrypt returned 0
950 even though it was supposed to return -1. Fixed this. The
951 affected file is lib/silccore/silcpacket.c.
953 * Do not replace the config files in /etc/silc (in make install)
954 if they already exist. Affected file ./Makefile.am.
956 * Do not send re-key packets immediately but through packet queue.
957 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
959 * Changed silc_net_check_host_by_sock to return FALSE if the
960 IP/DNS could not be resolved. Though, it returns the IP address
961 now even if it could not resolve it (but returns also FALSE).
962 Affected file lib/silcutil/silcnet.[ch].
964 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
966 * Added silc_pkcs_decode_identifier to decode the public key's
967 identifier. Affected file lib/silccrypt/silpkcs.[ch].
968 Added also silc_pkcs_free_identifier. Added also new context
969 SilcPublicKeyIdentifier.
971 * Added -S option to the silc client. It is used to dump the
972 contents of the specified public key file.
974 * Changed the PKCS api to return the public key length when
975 setting the public key.
977 * Fixed a fatal bug in the public and private key file loading.
978 Affected file lib/silccrypt/silcpkcs.c.
980 * Execute the packet parsing for client with zero (0) timeout
981 if the protocol is active. Affected file silcd/server.c.
983 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
985 * Made the key generation options to the silcd program. Added
986 -C option, equivalent to client's option.
988 * Added new [ServerKeys] config section to the server. It
989 configures the server's public and private key.
991 * Defined generic Public Key Payload into the protocol
992 specification to send specific type of public keys and
995 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
996 public key or certificate.
998 * Implemented the GETKEY command to the server and to the
999 client library and on user interface.
1001 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

1033 lib/silcclient/client.h.
1037 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1039 * Do not ask whether user wants to use the negotiated private key
1040 for private messages, just use it. Affected file is
1041 silc/local_command.c.
1043 * Added `send_enc_key' and `enc_key_len' fields to the
1044 SilcIDListData structure since they are needed in the re-key
1045 phase. Affected file is silcd/idlist.[ch].
1047 * Implemented the simple re-key protocol into the server.
1048 Affected files silcd/server.c and silcd/protocol.[ch]. The

1064 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1065 int64 of at least the xintXX size. If void * is less that 4
1066 bytes uint32 * will be used. Defined bool as boolean.
1068 * Changed _ALL_ unsigned long and unsigned int to uint32,
1069 unsgined short to uint16 in the source tree.
1071 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1072 not handle clients that has entry->data.registered == FALSE.
1073 They are not in the network anymore. Affected file is
1076 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1078 * Implemented the sending of the SERVER_SIGNOFF notify in the
1079 server. Affected file is silcd/server.c.

1090 implemnted the printing of the SERVER_SIGNOFF info to the
1091 application. Affected file silc/client_ops.c.
1093 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1094 if the deleting was successful. Affected file silcd/idlist.[ch].
1096 * Added support for public key authentication in the connection
1097 authentication protocol in the client library. Affected file
1098 lib/silcclient/protocol.c.
1100 * Changed the server's silc_idlist_get_clients_by_* interface
1101 to support already allocated array so that new entries may be
1102 added to pre-allocated array. Affected file silcd/idlist.[ch].
1103 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1104 and command replies.
1106 * All command reply functions in the server now calls the
1107 pending command callback even if error occured. This way the
1108 error will be delivered to the client as well. Affected files
1109 silcd/command.c and silcd/command_reply.c.
1111 * Fixed INFO command to return local server's info if no server
1112 was provided. Affected file lib/silcclient/command.c.
1114 * Removed RESTART command for good. Updated the code and the
1117 * Rewrote parts of the task system. It is a bit simpler now.
1118 Removed unsued task priorities. The affected files are
1119 lib/silcutil/silctask.[ch].
1121 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1123 * Moved the USERS printing from the library to the application.
1124 Affected files lib/silcclient/command.c and silc/client_ops.c.
1126 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1130 * Added channel key re-key support. The re-key is perfomed
1131 only by the router and is done once in an hour. Added `rekey'
1132 field to the SilcChannelEntry in the server. Affected files
1133 silcd/server.c and silcd/idlist.h.
1135 * Added silc_task_unregister_by_context into the file
1136 lib/silcutil/silctask.[ch].
1138 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1140 * Added SILC_UMODE_GONE mode to indicate when the client is not
1141 present in the SILC network. Added also support to the local
1142 command AWAY that will set this mode. Added support of showing
1143 "xxx is gone" in WHOIS command. The USERS command shows the
1144 gone status as well.
1146 * Fixed setting server and router operator privileges in the
1147 server's UMODE command. Affected file silcd/command.c.
1149 * Merged the SKE KE1 and KE2 payloads into one payload. The
1150 new KE payload is equivalent to the old KE2 payload.
1152 Cleaned up the SKE Start Payload parsing. It now uses the
1153 simple buffer unformatting to do the parsing. A lot faster
1156 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1157 to the SKE that is used to indicate whether both of the SKE
1158 parties should perform authentication. By default only the
1159 responder performs authentication. By setting this flag also
1160 the initiator must do authentication. By default it is unset
1161 since in normal SKE case, client to server connection, only
1162 the responder should do authentication. When doing SKE between
1163 two clients both should perform authentication. Updated the
1164 code and the protocol specs.
1166 * A little fix to IDENTIFY command in the server. Search the
1167 client first by hash not nickname. Affected file is
1170 * Fixed the silc_client_close_connection to support closing
1171 the client to client connections wihtout deleting too much
1172 data. Affected file lib/silcclient/client.c.
1174 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1175 are received if protocol used to be active but is not anymore
1176 the application would crash due to NULL pointer dereference.
1177 Affected files silcd/server.c and lib/silcclient/client.c.
1179 * Added `hash' field to the SilcClientConnection to include
1180 the hash function negotiated in the SKE protocol.
1182 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1183 to set the channel founder authentication data. A client can
1184 claim the founder rights later by providing the authentication
1185 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1186 This way the channel founder can regain the channel founder
1187 privileges even it is left the channel. This works only on
1188 local server and the client must be connected to the same
1189 server to be able to regain the founder rights. Updated the
1190 protocol specs accordingly.
1192 Added support to the CMODE command in the client to set the
1193 founder auth data. Read the README to see how to set it.
1195 Added support to the CUMODE command to claim the founder
1196 rights. Read the README to see how to do it.
1198 Added support for the founder authentication to the Channel
1199 Entry in the server. Affected file silcd/idlist.h.
1201 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1202 server's CMODE command. Affected file silcd/command.c.
1204 * Added the following new functions into lib/silccore/silcauth.[ch]:
1205 silc_auth_get_method and silc_auth_get_data.
1207 * The server now saves the remote hosts public key to the
1208 SilcIDListData pointer. Affected file silcd/protocol.c.
1210 * The normal server now does not remove the channel entry from
1211 the cache if the founder authentication data is set. It used
1212 to remove it if the founder was the last one on the channel on
1213 the server and left the channel. The auth data is saved and
1214 if the channel is re-joined later the old entry is used with
1215 the old auth data. Affected files silcd/command_reply.c and
1218 * Removed the `pkcs' field from the SilcIDListData structure
1219 in the server; it is not used. Affected file silcd/idlist.h.
1221 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1223 * Fixed packet processing on slow links. Partial packets were
1224 never re-processed because the incoming data buffer was cleared
1225 by the application. Application must not directly clear the
1226 sock->inbuf, the packet processing routines handle it. Fixed
1227 this in client library and in server.
1229 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1231 * Fixed the WHOIS and IDENTIFY send reply function to really
1232 check whether to send list or just one entry. Affected file
1235 * Cleaned up the LEAVE command's channel key distribution. The
1236 affected file silcd/command.c.
1238 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1239 can enforce the channel mode as well. In that case the ID
1240 includes the ID of the server. The code now enforces the
1241 mode change if the router have different mode than the server.
1243 * The notify client operation with CMODE_CHANGE notify can now
1244 return NULL client_entry pointer if the CMODE was not changed
1245 by client. Application must check for this.
1247 * Added <Server ID> argument to INFO command to support server
1248 info fetching by Server ID.
1250 * Added silc_server_announce_get_channel_users to get assembled
1251 packets of channel users of the specified channel. Affected
1252 file silcd/server.[ch].
1254 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1255 was freed underneath the ID Cache.
1257 * Re-announce clients when the server received CHANNEL_CHANGE
1258 notify from the router. Affected file silcd/packet_send.c.
1260 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1263 crashed since it did not handle the fact that there is no cipher
1264 called "3" and didn't check the error condition. Now fixed.
1266 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1267 flag. It can be used to send message requests.
1269 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Implemented the RESTART command in the client.
1273 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1274 notice type messages. Added notice printing to the user
1277 * The channel keys are not re-generated if the channel's mode
1278 is PRIVKEY, ie private key on the channel exists. Affected
1279 files silcd/server.c and silcd/command.c.
1281 * Fixed a little bug in channel message delivery when channel
1282 private keys are set in the server. Affected file is
1283 silcd/packet_send.c.
1285 * Changed the setting on channel->on_channel = TRUE from the
1286 silc_client_save_channel_key to the JOIN command reply. The
1287 key payload is not received if the private channel key is set.
1288 Affected file lib/silcclient/command_reply.c and the
1289 lib/silcclient/client_channel.c.
1291 * When the CMODE_CHANGE notify is sent and the channel private
1292 key mode is removed the channel key must be re-generated in
1293 other cells as well. Added this support for the router in the
1294 silcd/packet_receive.c.
1296 * Added new local command NOTICE to send notice message on
1297 channel. Affected file silc/local_command.[ch].
1299 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1301 * Added new local command ME to the client. It is used to send
1302 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1303 some action. Affected file silc/local_command.[ch].
1305 * Changed channel_message and private_message client operations
1306 to deliver the message flags to the application. Added also
1307 the `flags' arguments to the silc_client_send_channel_message
1308 and silc_client_send_private_message functions. Affected file
1311 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1313 * Redefined the Private Message Payload to support private message
1314 keys and to support the new private message flags. Updated
1315 the protocol specs. Flags makes it possible to have for example
1316 CTCP style messages.
1318 * Added new type SilcPrivateMessagePayload and defined an API
1319 for it in the lib/silcclient/silcprivate.[ch].
1321 * Tested private message private keys successfully. Tested the
1322 private message key set, unset and list commands with the new
1325 * Redefined the Channel Message Payload to include the channel
1326 message flags (equal with private message flags) to support
1327 for example CTCP style messages.
1329 * Defined some of the message (for channel and private message)
1330 flags. Updated the protocol specs and added the flags to the
1331 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1333 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1335 * Added SilcKeyAgreementStatus type to the key agreement routines
1336 to indicate the current status and error if one occured.
1337 The status types are defined in the lib/silcclient/silcapi.h.
1339 * Added new local command KEY that is used to set and unset private
1340 keys for channels, set and unset private keys for private messages
1341 with remote clients and to send key agreement requests and
1342 negotiate the key agreement protocol with remote client. The
1343 key agreement is supported only to negotiate private message keys,
1344 it currently cannot be used to negotiate private keys for channels,
1345 as it is not convenient for that purpose.
1347 * Fixed a minor pending callback setting bug in the function
1348 silc_client_get_client_by_id_resolve, now the function works.
1349 Affected file lib/silcclient/idlist.c.
1351 * Added function silc_net_get_local_port to get local bound
1352 port by socket. Added to lib/silcutil/silcnet.[ch].
1354 * Added `sockets' and `sockets_count' fields to the SilcClient
1355 object. They hold the sockets of the listenning sockets in
1356 the client. Listenning sockets may be for example the key
1357 agreement server. Affected file lib/silcclient/client.[ch].
1358 Added functions the silc_client_add_socket and the
1359 silc_client_del_socket. They are exported to the application
1362 * Added ~./silc/clientkeys to support other client's public keys.
1364 * Renamed verify_server_key client operation to verify_public_key
1365 and added one argument to indicate the type of the connection
1366 (server, client etc.).
1368 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1370 * Added silc_server_connection_auth_request to handle the
1371 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1372 silcd/packet_receive.[ch].
1374 * Added silc_server_send_connection_auth_request into the
1375 silcd/packet_send.c to send the connection auth request packet.
1377 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1380 * Fixed the public key authentication in responder side in the
1381 server. The `auth_data' pointer includes the SilcPublicKey
1382 not the path to the public key. Affected file silcd/protocol.c.
1384 * Implemented the public key authentication in the initiator side
1385 in the server. Affected file silcd/protocol.c.
1387 * Removed the [RedirectClient] config section from the server
1388 configuration. Is not needed and I don't want to implement it.
1390 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1392 * Cleaned up the CMODE command in the server. It now works
1393 correctly and supports all the modes defined in the protocol.
1394 Affected file is silcd/command.c.
1396 * Added `hmac_name' field to the SilcChannelEntry in the server
1397 to hold the default HMAC of the channel. It can be set when
1398 creating the channel (with JOIN command). Affected files
1401 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1402 type to indicate the change of the current cipher and hmac
1403 on the channel. Client can safely ignore the <cipher> argument
1404 (if it chooses to do so) since the CHANNEL_KEY packet will
1405 force the channel key change anyway. The <hmac> argument is
1406 important since the client is responsible of setting the new
1407 HMAC and the hmac key into use.
1409 * Fixed the CMODE command in the client library as well.
1411 * Tested CMODE command in router environment successfully.
1413 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1415 * Show the version of the remote client (or server) when connecting
1416 to the server. It is logged to the log file. Affected file
1417 is silcd/protocol.c.
1419 * Fixed the KILLED notify handling in the client library. The
1420 client must be removed from all channels when receiving the
1423 Also, do not remove the client entry when giving the KILL
1424 command but when the KILLED notify is received.
1426 * Removed silc_idlist_find_client_by_nickname from the server.
1427 Not needed anymore. Affected files silcd/idlist.[ch].
1429 * Implemented the CHANNEL_CHANGE notify type handling to the
1430 server. Affected file silcd/server.c.
1434 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1436 * Added silc_server_send_notify_invite to send the INVITE
1437 notify between routers.
1439 * Implemented the INVITE command correctly to the server.
1441 * Implemented the INVITE notify type handling in the server.
1443 * Implemented the INVITE command to the client library and on the

1448 * Added function silc_server_get_client_resolve to find the
1449 client entry by ID from all ID lists and then resolve it
1450 (using WHOIS) if it cannot be found. Affected file is
1453 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Implemented the BAN command to the client library.
1457 * The JOIN command in the server now checks the invite list
1460 * Changed the silc_command_reply_payload_encode_va and the
1461 silc_command_payload_encode_va to support that if argument is
1462 NULL it ignores and checks the next argument. Affected file
1463 lib/silccore/silccommand.c.
1465 * Added silc_server_send_notify_ban to send the BAN notify
1466 type between routers.
1468 * Chaned the silc_notify_payload_encode to support that if
1469 argument is NULL it ignores and checks the next argument.
1470 Affected file lib/silccore/silcnotify.c.
1472 * Tested ban lists in router environment successfully.
1474 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1476 * Implemented BAN command to the server, in silcd/command.[ch].
1478 * Removed the BAN and INVITE_LIST modes from the CMODE command
1481 * Added function silc_string_match to regex match two strings.
1482 Affected files lib/silcutil/silcutil.[ch].
1484 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1486 * Redefined parts of the SilcChannelEntry in the server to support
1487 the new ban and invite lists.
1489 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1491 * Redefined the INVITE command. The same command can be used to
1492 invite individuals to the channel but also to manage the invite
1493 list of the channel (to add to and remove from the invite list).
1494 Updated the protocol specs.
1496 * Added new command SILC_COMMAND_BAN that can be used to manage
1497 the ban list of the channel. Updated the protocol specs.
1499 * Removed the channel modes: the SILC_CMODE_BAN and the
1500 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1501 in the CMODE command. The equivalent features are now available
1502 using INVITE and BAN commands. Updated the protocol specs.
1504 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1505 in the network about change in the current ban list. The notify
1506 type is not used by the client.
1508 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1509 support the invite lists.
1511 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1513 * Added new function silc_string_regexify that converts string
1514 including wildcard characters into regex string that can
1515 be used by the GNU regex library. Added into the file
1516 lib/silcutil/silcutil.[ch].
1518 Added silc_string_regex_combine to combine to regex strings
1519 into one so that they can be used as one regex string by
1520 the GNU regex library. Added into the file
1521 lib/silcutil/silcutil.[ch].
1523 Added silc_string_regex_match to match two strings. It returns
1524 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1526 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * Imported GNU regex to the soruce tree into lib/contrib.
1529 Fixed some compiler warning from the regex.c.
1531 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Fixed MOTD command in the server to work in router environment.
1535 * Fixed the MOTD command in the client library to support
1536 the server argument in the command.
1538 * Added `nickname_len' argument to the silc_idlist_add_client
1539 in the server, as the `nickname' argument may be binary data
1542 * Added silc_idlist_get_channels to return all channels from
1545 * Implemented LIST command to the server. Affected file is
1548 * Implemented the LIST command to the client library and on the
1551 * Added [<user count>] argument to the LIST command reply.
1552 With private channels the user count is not shown.
1554 * Updated TODO and README.
1556 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1558 * The client entry's data.registered must be TRUE even with
1559 global client entry on global client list. The data.registered
1560 is used to check whether the client is anymore in the network,
1561 for example with WHOWAS command so it must be valid.
1563 * Fixed the WHOWAS command in the server. It now actually works
1564 in router environment. Added function into silcd/command_reply.c
1565 silc_server_command_reply_whowas_save.
1567 * Added silc_idlist_purge function to the silcd/idlist.c
1568 to periodically purge the ID Cache.
1570 * Fixed INFO command in the server. It works now in router
1571 environment. Added <server name> argument to the INFO command
1572 reply. Updated the protocol specs.
1574 * Fixed minor bug in silc_idcache_purge to not purge if the
1575 expire value is zero.
1577 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1578 they were buggy because of the WHOWAS information.
1580 * Fixed local command MSG to handle the async resolving of
1581 the remote client properly. It used to fail the first MSG.
1582 Affected file silc/local_command.c.
1584 * Added `data_len' field to SilcIDCache context.
1586 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1588 * Update TODO. Todo in commands in the server.
1590 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

1593 used by routers as broadcast packet to inform other routers
1594 about the changed user mode.
1596 Implemented the notify handling in the server. Affected file is
1597 silcd/packet_receive.c. Added the function
1598 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1600 * Added new generic Channel Payload and deprecated the New Channel
1601 Payload. The New Channel Payload is now the generic Channel
1604 * Added new argument `mode' to the silc_server_send_new_channel
1605 as it is required in the Channel Payload now.
1607 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1608 and created a new and real SilChannelPayload to represent the
1609 new generic Channel Payload. Implemented the encode/decode
1610 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1612 * Added silc_server_get_client_channel_list to return the list
1613 of channels the client has joined for WHOIS command reply.
1614 Affected file silcd/server.[ch].
1616 * Implemented the channel list sending in the WHOIS command reply
1617 in server and in the client.
1619 Implemented the channel list displaying on the user interface
1620 as well. Affected file silc/client_ops.c.
1622 * Added silc_channel_payload_parse_list to parse list of Channel
1623 Payloads. It returns SilcDList list of SilcChannelPayloads.
1624 Client for example can use this function to parse the list of
1625 channels it receives in the WHOIS command reply. The caller
1626 must free the list by calling silc_channel_payload_list_free.
1627 Affected files lib/silccore/silcchannel.[ch].
1629 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1631 * Added one new argument <user mode> to the WHOIS command reply
1632 to return the mode of the user in SILC. Updated the protocol
1635 Implemented it to the server and client.
1637 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1639 * Fixed the mode printing on the user interface on joining.
1640 Affected file silc/client_ops.c.
1642 * Implemented the UMODE command and user modes in general to the
1643 client library and to the user interface.
1645 * Implemented the UMODE command to the server.
1647 * The server now sends UNKNOWN_COMMAND error status if client sends
1648 unknown command. Affected file silcd/command.c.
1650 * All server commands now handle the command identifier the right
1651 way when sending the command reply to the client. The client can
1652 use to identify the command replies with the identifier.
1654 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1656 * Added silc_server_get_client_route to resolve the route to
1657 the client indicated by the client ID. Affected file is
1660 * Added silc_server_relay_packet as general function to relay
1661 packet to arbitrary destination. This deprecates functions
1662 like _send_private_message_key, _relay_notify etc. Affected
1663 file is silcd/packet_send.[ch].
1665 Removed silc_server_send_key_agreement,
1666 silc_server_send_private_message_key and
1667 silc_server_packet_relay_notify functions from the file
1668 silcd/packet_send.[ch].
1672 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1673 server. Affected file silcd/packet_receive.[ch].
1675 * Implemented the KILL command to the client. Implemented the
1676 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1677 Affected files lib/silcclient/command[_reply].c and
1678 lib/silcclient/client_notify.c. Implemented the KILL notify
1679 printing in the user inteface.
1681 * Fixed a lot silc_parse_nick memory leaks from the client
1682 library in the file lib/silcclient/command.c.
1684 * Changed the silc_server_send_notify_on_channels's `sender'
1685 argument from SilcSocketConnection to SilcClientEntry to
1686 check the sender as entry and not as connection object and not
1687 to send to the client provided as argument. The affected file
1688 is silcd/packet_send.[ch].
1690 * The notify packets that are destined directly to the client used
1691 to not to be processed by the server. Now changed that and the
1692 server processes all notify packets. After relaying the packet
1693 to the client the notify packet is processed in the server.
1695 * The silc_server_free_client_data now checks whether there is
1696 pending outgoing traffic for the client and purges the data to
1697 the network before removing the client entry.
1699 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1701 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1702 an client is killed from the SILC Network. Updated the protocol
1705 Added new function silc_server_send_notify_killed to the
1706 silcd/packet_send.[ch].
1708 * Added function silc_server_packet_relay_notify to relay notify
1709 packets that are destined directly to a client. In this case
1710 the server does not process the notify packets but merely relays
1711 it to the client. Affected file silcd/packet_send.[ch].
1713 Added also silc_server_packet_process_relay_notify to check
1714 whereto relay the notify. Affected file is
1715 silcd/packet_receive.[ch].
1717 * Implemented the KILL command to the server.
1721 * Added the backup schema desgined last fall to the protocol
1722 specs for everyone to see. The specification is in the
1723 *-spec-xx.txt draft and the packet type definitions for the
1724 backup routers is in *-pp-xx.txt draft. Thusly, added also
1725 new packet type SILC_PACKET_CELL_ROUTERS.
1727 * A big security problem in the implementation discovered. The
1728 signoff of an client did not cause new channel key generation
1729 which it of course should've done. The channel keys must be
1730 always re-generated when client leaves (or signoffs) the channel.
1731 The silc_server_remove_from_channels funtion now handles
1732 the channel key re-generation.
1734 * Added `sender' argument to the silc_server_send_notify_on_channels
1735 to not to send the client provided as argument. Affected file
1736 silcd/packet_send.[ch].
1738 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1740 * Implemented OPER and SILCOPER commands into the server and
1743 * Added silc_auth_verify and silc_auth_verify_data to verify
1744 the authentication directly from the authentication payload.
1745 It supports verifying both passphrase and public key based
1746 authentication. Affected file lib/silccore/silcauth.[ch].
1748 * Added `hash' field to the SilcIDListData structure. It is the
1749 hash negotiated in the SKE protocol. Affected file is
1752 * Slight redesigning of the SilcAuthPayload handling routines.
1753 Do not send SilcPKCS but SilcPublicKey as argument.
1755 * Implemented the public key authentication support to the
1756 serverconfig. The public key is loaded from the provided path
1757 and saved as authentication data to void * pointer. Thus,
1758 changed the unsigned char *auth_data to void *auth_data;
1760 * Fixed SHUTDOWN command to send the reply before the server
1761 is shutdown. :) Affected file silcd/command.c.
1763 * Fixed fatal bug in CONNECT command. The hostname was invalid
1764 memory and server crashed. Affected file silcd/command.c.
1766 * Fixed fatal bug in CLOSE command. The server_entry became
1767 invalid but was referenced later in the command. Affected file
1770 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1772 * Fixed fatal bug in failure packet handling. Server ignored
1773 the failure and thus crashed when it came.
1777 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1779 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1780 that the command may be executed only once in (about) 2 seconds.
1781 The old SILC_CF_LAG flag is same but allows command bursts up
1782 to five before limiting.
1784 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1785 server code. Various commands now includes the CF_LAG_STRICT
1786 flag to disallow any kind of miss-use of the command.
1788 * Fixed the silc_buffer_unformat to not to allocate any data
1789 if the length of the data is zero. It used to allocate the
1790 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1792 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1794 * Changed the format of AdminConnection configuration section
1795 in the server. Added username of the admin to the format.
1796 Affected files silcd/serverconfig.[ch].
1798 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1799 to return admin configuration data by host, username and/or
1802 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1804 * Implemented WHOWAS command to the server. Added the functions:
1806 silc_server_command_whowas_parse,
1807 silc_server_command_whowas_send_reply,
1808 silc_server_command_whowas_from_client and
1809 silc_server_command_whowas_from_server
1811 * Added <Client ID> argument to the WHOWAS command reply. Updated
1812 the protocol specs accordingly.
1814 * Implemented WHOWAS command and command_reply to the client
1817 Implemented the WHOWAS printing on the user interface.
1819 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1821 * Added new argument to the WHOWAS command reply, the real name.
1822 It is an optional argument. Updated the protocol specs.
1824 * Added SilcIDCacheDestructor callback that is registered when
1825 the SilcIDCache is allocated. The callback is called when
1826 an cache entry in the ID Cache expires, or is purged from the
1827 cache. Added into lib/silccore/idcache.[ch].
1829 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1830 to destruct the client entries when the cache entry expires.
1831 Other ID Cache's in server and in the client library ignores
1834 * If the ID Cache entry's `expire' field is zero then the entry
1835 never expires. Added boolean `expire' argument to the
1836 silc_idcache_add function in the lib/silccore/idcache.[ch].
1837 If it is TRUE the default expiry value is used.
1839 * Added silc_server_free_client_data_timeout that is registered
1840 when client disconnects. By default for 5 minutes we preserve
1841 the client entry for history - for WHOWAS command.
1843 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1845 * Added support to the server to enforce that commands are not
1846 executed more than once in 2 seconds. If server receives
1847 commands from client more frequently, timeout is registered
1848 to process the commands. Affected file silcd/command.c.
1849 Added new function silc_server_command_process_timeout.
1851 * Changed NICK_NOTIFY handling in client library to check that
1852 if the client's nickname was changed, so there is no need to
1853 resolve anything from the server.
1855 * Removed error printing from the WHOIS and IDENTIFY commands.
1856 If error occurs then it is ignored silently in the client library.
1857 The application, however, may map the received error to
1858 human readable error string. The application currently maps
1859 the NO_SUCH_NICKNAME error to string.
1861 * Made the command status message public to the application. Moved
1862 them from lib/silcclient/command_reply.c to
1863 lib/silcclient/command_reply.h. The application can map the
1864 received command status to the string with the
1865 silc_client_command_status_message function.
1867 * Added check to the server to check that client's ID is same
1868 as the Source ID in the packet the client sent. They must
1871 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1873 * Added dist-bzip hook to the Makefile.am to make bzip2
1874 compressed distributions.
1876 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1878 * Server now enforces the maximum length for the nickname and
1879 the channel as protocol specification dictates. 128 bytes for
1880 nickname and 256 bytes for channel name.
1882 * Moved the WHOIS printing to the application. The client libary
1883 does not print out the WHOIS information anymore, the application
1884 must do it. Renamed silc_client_command_reply_whois_print to
1885 the silc_client_command_reply_whois_save.
1887 The client's idle time is also sent to the application now, and
1888 the idle is shown on screen.
1890 * Added silc_client_command_reply_identify_save to save the
1891 received IDENTIFY entries.
1893 * Do not check for channel private keys in message sending and
1894 reception if the channel does not have the PRIVKEY mode set.
1895 Affected file lib/silclient/client_channel.c.
1897 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1899 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1900 just surfaced after chaning the JOIN procedure.
1902 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1904 * Added silc_client_get_clients_by_list to get client entries
1905 from Client ID list, that is returned for example by JOIN
1906 and USERS command replies. The application should use this
1907 function for example when JOIN command reply is received to
1908 resolve the clients already on the channel (library does not
1909 do that anymore as USERS command reply is not used in the JOIN
1910 procedure anymore). Affected files lib/silcclient/silcapi.h and
1911 lib/silcclient/idlist.c.
1913 * JOIN command reply and USERS command reply returns now SilcBuffer
1914 pointers instead of unsigned char pointers when returning
1915 the client list and mode list.
1917 * Added <Client ID> argument to the JOIN command reply, mainly
1918 for the server to identify for which client the command was
1919 originally sent. Updated protocol specs accordingly.
1921 * Added SilcDlist private_key pointer to the SilcChannelEntry
1922 in the client to support the channel private keys. Affected
1923 file is lib/silcclient/idlist.h.
1925 * Added SilcChannelPrivateKey argument to the function
1926 silc_client_send_channel_message so that application can choose
1927 to use specific private ke if it wants to. If it is not provided,
1928 the normal channel key is used, unless private keys are set.
1929 In this case the first (key that was added first) is used
1930 as the encryption key.
1932 * Implemented the support for channel private key handling.
1933 Implemented the following functions:
1935 silc_client_add_channel_private_key,
1936 silc_client_del_channel_private_keys,
1937 silc_client_del_channel_private_key,
1938 silc_client_list_channel_private_keys and
1939 silc_client_free_channel_private_keys
1941 Affected file lib/silcclient/client_channel.c.
1943 * Added the support for the private keys in the channel message
1944 sending and encryption and in the message reception and
1945 decryption. Affected funtions are
1946 silc_client_send_channel_message and silc_client_channel_message.
1948 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Added SKE's key verify callback to the client library's
1951 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1953 * Removed the statement that server (or router) must send USERS
1954 command reply when joining to the channel so that the client
1955 knows who are on the channel. Instead, the client list and
1956 client's mode list is now sent in the JOIN command reply to the
1957 client who joined channel. This is better solution.
1959 * Added function silc_server_get_users_on_channel and function
1960 silc_server_save_users_on_channel to the silcd/server.[ch].
1962 * Removed function silc_server_command_send_users from the
1965 * Do not show topic on the client library anymore. The topic is
1966 sent in the command reply notify to the application and the
1967 application must show the topic now.
1969 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1971 * Added client searching by nickname hash into the IDENTIFY and
1972 WHOIS commands in the server as they were clearly missing from
1973 them. Affected file is silcd/command.c.
1975 * Fixed a bug in private message receiving in the client library.
1976 The remote ID was freed and it wasn't supposed, now it is
1979 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1981 * Minor fix to the channel payload; allocate the data area, as it
1982 needs to be of specific length.
1984 * If the key agreement port is zero then the operating
1985 system will define the bound port. Affected files are
1986 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1988 * Added new function silc_channel_payload_decrypt into the file
1989 lib/silccore/silcchannel.[ch].
1991 * Moved the channel message etc, check from silc_packet_decrypt
1992 to applications. The library calls now a generic
1993 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1994 when the packet is either normal or special. This was done to
1995 allow more wide range of checking that was not allowed when
1996 the code was in library. Now applications can do virtually any
1997 checks to the packet and return to the library the decision how
1998 the packet should be processed. Affected files are
1999 lib/silccore/silcpacket.[ch].
2001 Added silc_server_packet_decrypt_check to the server and
2002 silc_client_packet_decrypt_check to the client library.
2004 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2005 to send with specified source and destination information.
2007 * Channel message delivery between routers was broken after the
2008 channel key distribution was fixed earlier. The channel key
2009 was used be to distributed to other routers as well which is not
2010 allowed by the protocol. Now this is fixed and channel keys
2011 really are cell specific and the channel message delivery between
2012 routers comply with the protocol specification.
2014 * Fixed various commands in server to check also the global list
2015 for the channel entry and not just the local list. The affected
2016 file silcd/command.c.
2018 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2020 * Added assert()s to buffer formatting and unformatting routines
2021 to assert (if --enable-debug) when error occurs. Affected
2022 file: lib/silcutil/silcbuffmt.c.
2024 * Changed to auto-reconnect to check whether the remote host is
2025 router and register the re-connect timeout if it is. It used
2026 to check that whether we are normal server, but router must do
2027 auto-reconnect with another router as well. Affected file
2030 * Removed the [<key len>] option from CMODE command as the cipher
2031 name decides the key length, nowadays. See the defined ciphers
2032 from the protocol specification.
2034 * Added [<hmac>] option to the CMODE command to define the HMAC
2035 for the channel. Added SILC_CMODE_HMAC channel mode.
2037 * Added [<hmac>] option for the JOIN command so that user can
2038 select which HMAC is used to compute the MACs of the channel
2041 * Added Hmac field to the Channel Message Payload. The integrity
2042 of plaintext channel messages are now protected by computing
2043 MAC of the message and attaching the MAC to the payload. The
2044 MAC is encrypted. Now, it is clear that this causes some
2045 overhead to the size of the packet but rationale for this is that
2046 now the receiver can verify whether the channel message decrypted
2047 correctly and also when private keys are set for the channel the
2048 receiver can decrypt the packet with several keys and check from
2049 the MAC which key decrypted the message correctly.
2051 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2052 lib/silccrypt/silccipher.[ch].
2054 * Added silc_hash_len to return the digest length into the
2055 lib/silcrypt/silchash.[ch].
2057 * Rewrote parts of Silc Channel Payload interface in the
2058 lib/silccore/silcchannel.[ch]. The encode function now also
2059 encrypts the packet and parse function decrypts it.
2061 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * Fixed a minor formatting bug in the SKE's key material processing.
2064 It actually might have processed the keys wrong way resulting
2067 * Redefined the mandatory HMAC algorithms and added new algorithms.
2068 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2069 and hmac-md5 truncated to 96 bits. The mandatory is now
2070 hmac-sha1-96. Rest are optional (including the one that used
2071 to be mandatory). Rationale for this is that the truncated HMAC
2072 length is sufficient from security point of view and can actually
2073 make the attack against the HMAC harder. Also, the truncated
2074 HMAC causes less overhead to the packets. See the RFC2104 for
2077 * Added new [hmac] configuration section. The SKE used to use
2078 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2079 is of course wrong. The official names that must be proposed in
2080 the SKE are the ones defined in the protocol specification
2081 (hmac-sha1-96 for example). The user can configure any hmac
2082 using any hash function configured in the [hash] section. At
2083 least, the mandatory must be configured.
2085 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2087 * Added HMAC list to the SKE proposal list. It has now both
2088 hash algorithm list and HMAC list. This makes the protocol
2089 incompatible with previous versions. The SKE now seems to work
2090 the way it is supposed to work, for the first time actually.
2092 * Defined plain Hash algorithms to the protocol specification.
2095 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2097 * Implemented support for key agreement packets into the server.
2098 Added functions silc_server_key_agreement and
2099 silc_server_send_key_agreement. Other than these functions,
2100 server has nothing to do with this packet.
2102 * Added support for private message key packets into the server.
2103 Added functions silc_server_private_message_key and
2104 silc_server_send_private_message_key.
2108 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2109 called in the protocol's final callback instead in the END
2110 protocol state. This makes a little more sense and in the same
2111 time in client we can use the same protocol routines for normal
2112 key exchange and to key agreement packet handling as well.
2114 * Added to both client's and server's KE protocol context the
2115 SilcSKEKeyMaterial pointer to save the key material. We will
2116 bring the key material to the protocol's final callback by doing
2117 this. The final callback must free the key material.
2119 * Added SKE's packet_send callback into client's KE protocol
2120 context so that the caller can choose what packet sending function
2121 is used. This way we can use different packet sending when
2122 doing normal SKE when doing key agreement packet handling (in
2123 the key agreement packet handling we do not want to encrypt
2126 * Implemented the responder side of the key agreement routines
2127 in the client. The client can now bind to specified port and
2128 accept incoming key negotiation. The key material is passed
2129 to the application after the protocol is over.
2131 * Implemented the processing of incoming Key Agreement packet
2132 in the client. Added function silc_client_key_agreement to
2135 * Implemented the intiator side of the key agreement routines
2136 in the client. The client can now initiate key agreement with
2137 another remote client. The key material is passed to the
2138 application after the protocol is over.
2140 * Created client_keyagr.c to include all the key agreement
2143 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2144 SILC_TASK_CALLBACK except that it is not static.
2146 * Created client_notify.c and moved the Notify packet handling
2147 from the client.[ch] into that file.
2149 * Created client_prvmsg.c and moved all private message and
2150 private message key routines from the client.[ch] into that file.
2152 * Create client_channel.c and moved all channel message and
2153 channel private key routines from the client.[ch] into that file.
2155 * Changed silc_client_get_client_by_id_resolve to resolve with
2156 WHOIS command instead of IDENTIFY command, in the file
2157 lib/silclient/idlist.c.
2159 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2161 * Implemented the SKE's responder side to the Client library.
2163 * When FAILURE is received to the protocol do not trust it
2164 blindly. Register a timeout to wait whether the remote closes
2165 the connection as it should do it, only after that process the
2166 actual failure. This was changed to both client and server.
2168 * Added client_internal.h to include some of the structures
2169 there instead of client.h in lib/silcclient/.
2171 * Added function silc_task_unregister_by_callback to unregister
2172 timeouts by the callback function.
2174 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2176 * Some "Incomplete WHOIS info" errors has been appearing on the
2177 log files. Took away the entry->userinfo check from WHOIS
2178 reply sending. The entry->userinfo is now " " if client did not
2179 provide one. I thought this was fixed earlier but something
2180 is wrong still. Let's see if the error still appears.
2182 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2184 * Fixed a minor bug in the login when the channel key is
2185 re-generated in the server. It used to generate the key in
2186 wrong order and thus caused problems in the channel traffic.
2188 * Fixed a minor bug in channel key distsribution after
2189 KICK command. The key was not sent to the router even though
2192 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2194 * Added silc_ske_process_key_material_data as generic routine
2195 to process any key material as the SILC protocol dictates. The
2196 function is used by the actual SKE library but can be used by
2197 applications as well. This relates to the private message keys
2198 and the channel private keys since they must be processed the
2199 same way the normal SILC session keys. The protocol dictates
2200 this. Affected files: lib/silcske/silcske.[ch].
2202 Added also silc_ske_free_key_material to free the
2203 SilcSKEKeyMaterial structure.
2205 * Defined silc_cipher_set_key function to set the key for
2206 cipher without using the object's method function. The affected
2207 files: lib/silccrypt/silccipher.[ch].
2209 * Implemented silc silc_client_add_private_message_key,
2210 silc_client_add_private_message_key_ske,
2211 silc_client_del_private_message_key,
2212 silc_client_list_private_message_keys and
2213 silc_client_free_private_message_keys functions in the
2216 Added functions silc_client_send_private_message_key to send
2217 the Private Message Key payload and silc_client_private_message_key
2218 to handle incoming Private Message Key payload.
2220 * Added Cipher field to the Private Message Key payload to set
2221 the cipher to be used. If ignored, the default cipher defined
2222 in the SILC protocol (aes-256-cbc) is used.
2224 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2226 * Removed lib/silcclient/ops.h file.
2228 Redefined parts of the SILC Client Library API. Created new
2229 file silcapi.h that deprecates the ops.h file and defines the
2230 published Client Library API. Defined also private message key
2231 API and channel private key API into the file.
2233 This is the file that the application must include from the
2234 SILC Client Library. Other files need not be included by
2235 the application anymore.
2237 * Added new key_agreement client operation callback and also
2238 defined the Key Agreement library API for the application.
2240 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2242 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2243 is used by clients to request key negotiation between another
2244 client in the SILC network. If the negotiation is started it
2245 is performed using the SKE protocol. The result of the
2246 negotiation, the secret key material, can be used for example
2247 as private message key.
2249 Implemented the Key Agreement payload into the files
2250 lib/silccore/silauth.[ch].
2252 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2254 * Redefined ciphers for the SILC protocol. Added some new ciphers
2255 and defined the key lengths for the algorithms. Changed the
2256 code accordingly. The default key length is now 256 bits.
2258 * Fixed SKE key distribution function silc_ske_process_key_material
2259 when the key length is more than 128 bits. The default key
2260 length in SILC is now 256 bits.
2262 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2263 to indicate unsupported algorithm.
2265 * Renamed rijndael.c to aes.c and all functions as well.
2267 * Fixed a long standing channel key setting bug in client library.
2268 Weird that it has never surfaced before.
2270 * Fixed bug in channel deletion. If the entire channel is removed
2271 then it must also delete the references of the channel entry
2272 from the client's channel list as the client's channel entry and
2273 the channel's client entry share same memory.
2275 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2277 * Implemented CONNECT and SHUTDOWN commands in the client.
2279 * Implemented CLOSE command to the client.
2281 * Added the function silc_idlist_find_server_by_name into the
2282 files silcd/idlist.[ch].
2284 Added the function silc_idlist_find_server_by_conn into the
2285 files silcd/idlist.[ch].
2287 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2289 * DIE command was renamed to SHUTDOWN. Updated the both code
2292 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2293 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2295 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2298 * Added function silc_server_create_connection function to create
2299 connection to remote router. My server implementation actually
2300 does not allow router to connect to normal server (it expects
2301 that normal server always initiates the connection to the router)
2302 so the CONNECT command is only good for connecting to another
2305 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2307 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2308 or some other client was kicked from the channel.
2310 Implemented the handling of the notify type to both client
2313 Implemented silc_server_send_notify_kicked to send the KICKED
2314 notify. It is used to send it to the server's primary router.
2316 * Implemented the KICK command into server and client.
2318 * Added `query' argument to the silc_idlist_get_client function
2319 to indicate whether to query the client from server or not if
2322 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2323 to indicate that the client is not channel founder.
2327 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2329 * Removed the rng context from SilcPacketContext structure and
2330 changed that the packet routine uses the Global RNG API.
2332 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2334 * Added support for quit message that client can "leave" on the
2335 channel when it quits the SILC. It is ditributed inside the
2336 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2338 Added silc_server_free_client_data that will take the
2339 signoff message as argument.
2341 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2343 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Updated parts of the protocol specification to keep it up
2348 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2350 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2351 payloads in one packet.
2353 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2354 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2355 use now the new List flag.
2357 * Also deprecated the following packet types: REPLACE_ID,
2358 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2360 * Added list support for Notify packet in server.
2362 * Added silc_server_send_notify_channel_change to send the
2363 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2364 the silc_server_send_replace_id.
2366 * Added silc_server_send_notify_nick_change to send the
2367 NICK_CHANGE notify type. Deprecates the function
2368 silc_server_send_replace_id.
2370 * Added silc_server_send_notify_join to send the JOIN notify type.
2371 Deprecates the function silc_server_send_new_channel_user.
2373 * Added silc_server_send_notify_leave to send LEAVE notify type.
2374 Deprecates the function silc_server_send_remove_channel_user.
2376 * Added silc_server_send_notify_cmode and
2377 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2378 types. Deprecates the silc_server_send_set_mode function.
2380 * Added SERVER_SIGNOFF notify type to indicate that server has
2381 quit. This means that all clients on the channel from that
2382 server will drop. This can be also used when netsplit happens.
2384 Deprecated REMOVE_ID packet type since it is not needed anymore
2387 Added silc_server_send_notify_server_signoff to send the
2388 SERVER_SIGNOFF notify type. Deprecates the function
2389 silc_server_send_remove_id.
2391 Added also silc_server_send_notify_signoff to send the
2392 SIGNOFF notify type.
2394 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2395 SILC protocol from this day on. Changed the protocol
2396 specification as well.
2398 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2399 notify type. It is used between routers to notify about
2400 topic changes on a channel.
2402 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2405 * Partly updated the protocol specification to comply with the
2406 changes now made. It is still though a bit outdated.
2408 * The JOIN notify type now takes one extra argument <Channel ID>.
2409 The packet used to be destined to the channel but now the
2410 JOIN type may be sent as list thus it is impossible to
2411 destine it to any specific channel. By adding this argument
2412 it is again possible.
2414 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2416 * Added CREDITS file. The CHANGES and CREDITS file will appear
2417 in the distribution as well.
2419 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2422 types in the server's silcd/packet_receive.c.
2424 * Implemented CMODE and CUMODE to work in router environment.
2426 * Fixed minor encoding and decoding buglet from the
2427 lib/silccore/silcmode.c.
2429 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2432 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2434 * Changed all SilcConfigServer* and silc_config_server* to
2435 SilcServerConfig* and silc_server_config*, respectively.
2438 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2440 * Associated the ID (client or server ID) to the Authentication
2441 Payload to avoid any possibility of forging. Updated the
2442 protocol specification and the code accordingly.
2444 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * The RSA key length is now save to the RsaKey context in the
2447 key generation process in lib/silccrypt/rsa.c. The key length
2448 is now used to figure out the maximum size of the block allowed
2449 to be encrypted/signed.
2451 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2452 is equivalent to the silc_mp_mp2bin but does not allocate any
2455 * Changed silc_mp_mp2bin API to take length argument. If it is
2456 non-zero then the buffer is allocated that large. If zero, then
2457 the size is approximated using silc_mp_sizeinbase, which however
2460 * Created Global RNG API which is global RNG that application can
2461 initialize. After initializing, any routine anywhere in the
2462 code (including library) can use RNG without allocating a new
2463 RNG object. This was done to allow this sort of use of the
2464 RNG in code that has no chance to allocate RNG object. All
2465 applications currently allocate this and many routines in the
2466 library use this. Affected file lib/silccrypt/silcrng.[ch].
2468 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2469 it to use the Global RNG API.
2471 * Defined Authentication Payload into protocol specification that
2472 is used during SILC session to authenticate entities. It is
2473 used for example by client to authenticate itself to the server
2474 to obtain server operator privileges.
2476 Implemented this payload into the lib/silccore/silcauth.[ch].
2477 Implemented also routines for public key based authentication
2478 as the new protocol specification dictates.
2480 Moved definitions of different authentication methods from
2481 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2483 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2484 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2485 silc_pkcs_verify_with_hash functions into the file
2486 lib/silccrypt/silcpkcs.[ch].
2488 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * The client entry's userinfo pointer must be always valid.
2491 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2492 will fail since it requires the userinfo. Now, the userinfo
2493 is allocated as "" if actual userinfo does not exist. Actually,
2494 it must exist and it is totally Ok to drop client connections
2495 that does not announce the userinfo. However, we will make
2496 this workaround for now.
2498 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2499 to return the remote port by socket.
2501 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2503 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2504 SILC_SERVER_PENDING_EXEC and added an new macro
2505 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2506 data or when error occurs while processing the pending command.
2508 Added new argument `destructor' into silc_server_command_pending
2509 and to the SilcServerCommandPending object. This destructor is
2510 now called after calling the pending callback or if error occurs
2511 immediately. If error occurs the actual pending callback won't
2512 be called at all - only the destructor. The destructor may be
2513 NULL if destructor is not needed.
2515 All this applies for client library code as well. Similar
2516 changes were made there as well for the pending commands.
2518 In the client, the application must now allocate the
2519 SilcClientCommandContext with the silc_client_command_alloc
2522 * Added reference counter to the SilcServerCommandContext. Added
2523 function silc_server_command_alloc and silc_server_command_dup
2526 Same type of functions added to the client library for the same
2529 * Removed the cmd_ident from IDListData away since it is now
2530 global for all connections. It is the command identifier used
2531 in command sending and with pending commands. The affected file
2534 * Added reference counter to the SilcSocketConnection objecet to
2535 indicate the usage count of the object. The object won't be
2536 freed untill the reference counter hits zero. Currently only
2537 server uses this, and client ignores it. The client must be
2538 set to use this too later. The affected files are
2539 lib/silccore/silcsockconn.[ch]. Added also the function
2540 silc_socket_dup to increase the reference counter.
2542 This was mainly added because it is possible that the socket
2543 is removed underneath of pending command or other async
2544 operation. Now it won't be free'd and proper DISCONNECTING
2545 flags, etc. can be set to avoid sending data to connection that
2546 is not valid anymore.
2548 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2549 the connection. After that it sets SILC_SET_DISCONNECTED.
2550 It is, however, possible that the socket data is not still freed.
2551 The silc_server_packet_process now checks that data is not
2552 read or written to connection that is DISCONNECTED. The socket
2553 get's freed when the reference counter hits zero.
2555 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * Changed the client operation API: channel_message operation's
2558 `sender' is now the client entry of the sender, not the nickname
2559 and the `channel' is the channel entry, not the channel name.
2561 In the private_message operation the `sender' is now also the
2562 client entry of the sender not the nickname.
2564 Affected file is lib/silcclient/ops.h and all applications
2565 using the client operations.
2567 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2569 * Moved the calling of ops->connect() from connect_to_server_final
2570 into receive_new_id functin since that is the point when the
2571 client is actually allowed to send traffic to network. The
2572 affected file is lib/silcclient/client.c.
2574 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2576 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2577 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2578 (if needs broadcasting) instead of broadcasting the packets one
2579 by one which would make a burst in the network traffic.
2581 * Added `broadcast' argument to the functions in silcd/server.[ch]
2582 silc_server_create_new_channel[_with_id] to indicate whether
2583 to send New Channel packet to primary router.
2585 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2587 * Added new function into the silcd/server.[ch] files:
2588 silc_server_create_new_channel_with_id to create new channel with
2589 already existing Channel ID.
2591 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2592 lib/silccore/silcpacket.h. This packet is used t send list of
2593 Set Mode payloads inside one packet. Server uses this to set
2594 the modes for the channels and clients on those channels, that it
2595 announced to the router when it connected to it. The protocol
2596 specification has been updated accordingly.
2598 * The silc_server_new_channel did not handle the packet coming
2599 from normal server as it normally does not send that. However,
2600 when it announces its channels it does send it. Implemented
2601 the support for that.
2603 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2604 into the file lib/silccore/id.h.
2606 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2608 * Fixed memory leaks in the functions silc_idlist_del_client,
2609 silc_idlist_del_channel and silc_idlist_del_server in the file
2610 silcd/idlist.c. All of those leaked like a sieve.
2612 * Fixed some small memory leaks in the client's function
2613 silc_client_notify_by_server.
2615 * Added functions into silcd/server.c: silc_server_announce_clients,
2616 silc_server_announce_channels and silc_server_announce_server.
2617 These functions are used by normal and router server to announce
2618 to its primary router about clients, channels and servers (when
2619 router) that we own. This is done after we've connected to the
2622 These functions effectively implements the following packet types:
2623 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2624 and SILC_PACKET_NEW_ID_LIST.
2626 * Added new functions into the silcd/packet_receive.[ch]:
2627 silc_server_new_id_list, silc_server_new_channel_list and
2628 silc_server_new_channel_user_list to handle the incoming
2629 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2631 * Added support of changing Channel ID in the function
2632 silc_server_replace_id. If the server that announces a channel
2633 to the router already exists in the router (with same name but
2634 with different Channel ID), router is responsible to send
2635 Replace ID packet to the server and force the server to change
2636 the Channel ID to the one router has.
2638 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2639 client that the Channel ID has been changed by the router. The
2640 normal server sends this to the client. Client must start using
2641 the new Channel ID as the channel's ID.
2643 Implemented handling of this new type into lib/silcclient/client.c
2644 into the function silc_client_notify_by_server.
2646 * Added new function silc_idlist_replace_channel_id into the files
2647 silcd/idlist.[ch] to replace the Channel ID.
2649 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2651 * Call silc_server_command_identify_check always when processing
2652 the IDENTIFY command in silcd/command.c
2654 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2656 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2657 send keepalive packets. The packet can be sent by clients,
2658 servers and routers.
2660 Added function silc_socket_set_heartbeat into the file
2661 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2662 If not set, the heartbeat is not performed. The actual
2663 heartbeat is implemented in the low level socket connection
2664 library. However, application is responsible of actually
2667 Added silc_server_send_heartbeat to send the actual heartbeat
2668 packet into silcd/packet_send.[ch]. Server now performs
2669 keepalive with all connections.
2671 * Added silc_task_get_first function into lib/silcutil/silctask.c
2672 to return the timeout task with shortest timeout. There was a bug
2673 in task unregistration that caused problems. TODO has been
2674 updated to include that task system must be rewritten.
2676 * The client library will now resolve the client information when
2677 receiving JOIN notify from server for client that we know but
2678 have incomplete information.
2680 * Rewrote parts of silc_server_remove_from_channels and
2681 silc_server_remove_from_one_channel as they did not remove the
2682 channel in some circumstances even though they should've.
2684 * Encryption problem encountered in server:
2686 The LEAVE command used to send the Channel Key packet to the
2687 router immediately after generating it. However, the code
2688 had earlier sent Remove Channel user packet but not immediately,
2689 ie. it was put to queue. The order of packets in the router
2690 was that Channel Key packet was first and Remove Channel User
2691 packet was second, even though they were encrypted in the
2692 reverse order. For this reason, MAC check failed. Now, this
2693 is fixed by not sending the Channel Key packet immediately but
2694 putting it to queue. However, this is more fundamental problem:
2695 packets that are in queue should actually not be encrypted
2696 because packets that are sent immediately gets encrypted
2697 actually with wrong IV (and thus MAC check fails). So, packets
2698 that are in queue should be encrypted when they are sent to
2699 the wire and not when they put to the queue.
2701 However, the problem is that the current system has not been
2702 designed to work that way. Instead, the packet is encrypted
2703 as soon as possible and left to the queue. The queue is then
2704 just purged into wire. There won't be any fixes for this
2705 any time soon. So, the current semantic for packet sending
2708 o If you send packet to remote host and do not force the send
2709 (the packet will be in queue) then all subsequent packets to the
2710 same remote host must also be put to the queue. Only after the
2711 queue has been purged is it safe again to force the packet
2714 o If you send all packets immediately then it safe to send
2715 any of subsequent packets through the queue, however, after
2716 the first packet is put to queue then any subsequent packets
2717 must also be put to the queue.
2719 Follow these rules and everything works fine.
2721 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Added new function silc_server_remove_clients_by_server to
2724 remove all client entries from ID list when the server connection
2725 is lost. In this case it is also important to invalidate all
2726 client entires as they hold the invalid server entry. This
2727 fixes fatal bug when server has lost connection and will reconnect
2730 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2732 * Made some sanity checks to silc_server_daemonise like to check
2733 whether the requested user and group actually exists.
2735 * Added sanity check to SKE's silc_ske_responder_finish to check
2736 that the public and private key actually is valid.
2738 * Invalidate the client's nickname when receiving Replace ID
2739 packet and the Client ID is being replaced. This means that the
2740 server will query the nickname if someone needs it (client)
2743 * Sort the ID Cache in client library when the ID Cache data
2744 has changed (needs sorting).
2746 * Do not allow for SILC client to create several connections to
2747 several servers. The client does not support windows right now
2748 and generating multiple connections causes weird behaviour.
2750 Irssi-silc client does support windows and can handle several
2751 connections without problems, see: www.irssi.org and SILC plugin.
2753 * Fixed some places where client was added to the IDList. The
2754 rule of thumb is following (in order to get everything right):
2755 If the client is directly connected local client then the
2756 `connection' argument must be set and `router' argument must be
2757 NULL to silc_idlist_add_client function. If the client is not
2758 directly connected client then the `router' argument must
2759 bet set and the `connection' argument must be NULL to the
2760 silc_idlist_add_client function.
2762 * The funtion silc_server_packet_send_local_channel actually did
2763 not check whether the client was locally connected or not. It
2764 does that now. Fixed a bug related to LEAVE command.
2766 * Fixed Remove Channel User payload parsing bug in server's
2767 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2769 * The server's silc_server_save_channel_key now checks also the
2770 global ID list for the channel as it might not be in the local
2771 list. Fixed a bug related to LEAVE command.
2773 * Is this the end of the [<unknown>] buglet that has been lurking
2774 around for a long time? A little for loop fix in server's
2775 silc_server_command_whois_parse that is used by both IDENTIFY
2776 and WHOIS command. At least, this was a clear bug and a cause
2777 of one type of [<unknown>] buglet.
2779 * WHOIS and IDENTIFY commands call the function
2780 silc_server_command_[whois/identify]_check function even if
2781 we are not router server.
2783 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2785 * Added --with-gmp configuration option. If set the GMP
2786 is always compiled in the SILC source tree. If not set then
2787 it is checked whether the system has the GMP3 installed. If
2788 it has then the GMP won't be compiled (the system's headers
2789 and library is used), if it doesn't have it then the GMP is
2790 compiled in the SILC source tree.
2792 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2794 * Changed RSA private exponent generation to what PKCS #1
2795 suggests. We try to find the smallest possible d by doing
2796 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2797 not security fix but optimization.
2799 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Added new config entry [Identity] to fork the server and run
2802 it as specific user and group. A patch from Bostik.
2804 * Imported Dotconf configuration library into lib/dotconf.
2805 This will be used to create the SILC configuration files later.
2806 It will appear in the distsribution after this commit.
2808 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2810 * A big code auditing weekend happening. Auditing code for
2811 obvious mistakes, bugs and errors. Also, removing any code
2814 Removed files for being obsolete:
2816 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2817 inline in the file lib/silcutil/silcbuffer.h)
2819 o lib/silcutil/silcbufutil.c (the header has inline versions)
2821 Changed code to fix possible error conditions:
2823 o The buffer formatting routines now check that the destination
2824 buffer really has enough space to add the data. This applies for
2825 both buffer formatting and unformatting
2826 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2827 unformatting was changed to accomodate following rules:
2828 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2829 sent to the function while XXX_*STRING will not allocate or copy
2830 the data into the buffer. Instead it sets the pointer from the
2831 buffer into the pointer sent as argument (XXX_*STRING used to
2832 require that the pointer must be allocated already). This change
2833 makes this whole thing a bit more consistent and more optimized
2834 (note that the data returned in the unformatting with XXX_*STRING
2835 must not be freed now). The routines return now -1 on error.
2837 o Tried to find all code that use buffer_format and buffer_unformat
2838 and added return value checking to prevent formatting and
2839 especially unformatting errors and possible subsequent fatal
2842 o Changed ske->x and ske->KEY to mallocated pointers in
2843 lib/silcske/silcske.h. Fixed possible data and memory leak.
2845 o Added return value checking to all *_parse* functions. Fixed
2846 many memory leaks as well.
2848 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2849 so that buffer overflows would not happen. All code now also
2850 checks the return value as it can fail.
2852 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Added reconnection support to server if the normal server looses
2855 its connection to the router (for example if router is rebooted).
2856 The server performs normal reconnection strategy implemented
2857 to the server. Affected file silcd/server.c.
2859 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2861 * Added new packet type SILC_PACKET_SET_MODE that is used to
2862 distribute the information about changed modes (for clients,
2863 channels and clients channel modes) to all routers in the
2864 network. Updated the protocol specification accordingly.
2866 Added functions into silcd/packet_send.c and
2867 silcd/packet_receive.c: silc_server_send_set_mode,
2868 silc_server_set_mode.
2870 Added new files silcmode.[ch] into lib/silccore that implements
2871 the encoding and decoding of Set Mode Payload. Added new type
2872 SilcSetModePayload. Moved the definitions of different modes
2873 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2875 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2877 * Oops, a little mistake in server's connection authentication
2878 protocol. The protocol is not ended with FAILURE but with
2879 SUCCESS if the authentication is Ok. :) Affected file is
2882 * Implemented NICK_CHANGE notify handling in server in the file
2883 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2884 the local clients on the channel. After the changing nickname
2885 in router environment snhould work and the [<unknown>] nickname
2886 should appear no more.
2888 The silc_server_replace_id function that receives the Replace ID
2889 payload now sends the NICK_CHANGE notify type also in the file
2890 silcd/packet_receive.c
2892 * Changed WHOIS and IDENTIFY command to support the maximum amount
2893 of arguments defined in protocol specs (3328 arguments). This
2894 fixed a bug that caused problems when there were more than three
2897 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2899 * Added extra parameter, command identifier, to the
2900 silc_client_send_command so that explicit command identifier
2903 Changed that ID list routines uses specific command identifier
2904 when sending WHOIS/IDENTIFY requests to the server so that they
2905 can be identified when the reply comes back.
2907 Affected files lib/silcclient/command.[ch],
2908 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2910 * Added `sender' argument to silc_server_packet_send_to_channel
2911 to indicaet the sender who originally sent the packet to us
2912 that we are now re-sending. Ignored if NULL. Affected file
2913 silcd/packet_send.[ch].
2915 * Added some server statistics support in silcd/server_internal.h
2916 SilcServerStatistics structure and around the server code. Also
2917 send some nice statistics information when client is connecting
2920 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2922 * Fixed channel ID decoding in server's JOIN command reply in
2923 silcd/command_reply.c
2925 * Fixed braodcasting of replace ID payload to not to send it if
2926 we are standalone server in silcd/packet_receive.c.
2928 * Fixed all channel message sending routines to not to send
2929 packets to clients that has router set, since they are routed
2930 separately in the same function earlier. Affects file
2931 silcd/packet_send.c and all channel packet sending functions.
2933 * In USERS reply, res_argv[i] are not allocated, the table
2934 is allocated. Thus changed that free the table, not its
2937 * In server's whois_check and identify_check if the client is
2938 locally connected do not send any WHOIS commands - they are not
2941 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2943 * Fixed some minor bugs in client when sending WHOIS command. The
2944 arguments was in wrong order.
2946 * Removed statis function add_to_channel from server in
2947 silcd/command.c that was previously used with the joining but
2950 * Tested USERS command in router environment successfully with two
2951 routers, two servers and two clients.
2953 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2955 * Reorganized the USERS command and command reply in client library
2956 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2957 When the command is given by user we register a pending command
2958 callback that will reprocess the command after the reply has been
2959 received from the server. When reprocessing the packet we then
2960 display the information. Thus, the USERS information is displayed
2961 now in the command callback instead of in the command reply
2962 callback. The processing of the command is same as previously
2963 when server has sent the command reply in the JOINing process.
2965 * Added to USERS command in silcd/command_reply.c to join the client,
2966 we didn't use to know about, to the channel after we've created
2967 a client entry for it. Also, for clienet we did know already still
2968 check whether it is on the channel or not and add it if not.
2970 * Removed silc_server_command_join_notify as the function and its
2973 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Changed the client's pending command handling to the same as the
2976 server's pending command handling. It is also now possible to
2977 execute command reply functions from other command reply
2978 function as the function callbacks for commands and command
2979 replies are one and same. The pending commands are not static
2980 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2981 in client connection context. Thus, pending commands are server
2982 connection specific as it is convenient.
2984 Changed the function silc_client_command_pending and
2985 silc_client_command_pending_del and added new function
2986 silc_client_command_pending_check. Removed the
2987 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2990 * Added cmd_ident, current command identifier, to the client
2991 connection context in lib/silcclient/client.h to keep track on
2992 command identifiers used in command sending. Client's command reply
2993 function handling now supports the mandatory command identifiers.
2995 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2996 funtions in client to fully support pending command callbacks.
2998 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2999 as one of the arguments to the application in the command reply
3002 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3003 before first releasing SILC but came back. Now it is removed again
3004 and should come back nomore. The FORWARDED flag was used only
3005 by the JOINing procedure by forwarding the command packet to router.
3006 Now, the JOINing procedure has been changed to more generic (due
3007 to various router environment issues) and FORWARDED is not needed
3008 anymore for anything. The protocol specification is yet to be
3011 Now, removed silc_server_packet_forward from server and the flag
3012 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3014 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3016 * Renamed NAMES command to USERS command. The NAMES was named that
3017 due to historical reasons. Now it is renamed. Also, rewrote
3018 parts of the USERS command. The nickname list is not sent anymore
3019 by the server. Only Client ID and mode lists are sent in the USERS
3020 command. Changed this also to the protocol specification.
3022 The client now resolves the names and stuff after it receives
3023 the USERS list from the server when joining to the channel.
3025 * WHOIS and IDENTIFY commands has been changed to support multiple
3026 Client ID's per command. One can now search for multiple users
3027 in the network by sending only one WHOIS or IDENTIFY command.
3028 Changed the code and the protocol specifications.
3030 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3031 uses silc_server_command_whois_parse to parse the request. */
3033 * If normal server, do not parse the WHOIS and IDENTIFY requests
3034 before sending it to the router. Saves some time.
3036 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3038 * Fixed JOIN command on client library. Wrong number of arguments
3039 used to crash the client.
3041 * Added silc_server_channel_has_global function to check whether
3042 channel has global users or not.
3044 * Added silc_server_channel_has_local function to check whether channel
3045 has locally connected clients on the channel.
3047 * The silc_server_remove_from_one_channel now checks whether the
3048 channel has global users or not after given client was removed from
3049 the channel. It also checks whether the channel has local clients
3050 on the channel anymore. If it does not have then the channel entry
3051 is removed as it is not needed anymore.
3053 * The silc_server_notify now checks on JOIN notify whether the joining
3054 client is one of locally connected or global. If it is global then
3055 the channel has now global users on the channel and that is marked
3056 to the channel entry. Also, it now saves the global client to
3057 global list who is joining and JOINs it to the channel. This is
3058 for normal server, that is.
3060 Changed silc_server_send_notify_on_channel,
3061 silc_server_packet_relay_to_channel and
3062 silc_server_packet_send_to_channel check if we are normal server
3063 and client has router set (ie. global client) do not send the
3064 message to that client, as it is already routed to our router.
3066 * Implemented LEAVE notify type handling in silc_server_notify
3069 * Tested LEAVE command in router environment successfully. Tested
3070 with two routers, two servers and two clients.
3074 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3076 * Implemented SIGNOFF notify type handling in silc_server_notify
3079 * silc_server_remove_id now removes the client entry from all channels
3080 it has joined and thusly sends SIGNOFF notify type.
3082 * Rewrote the NAMES list generation in server by removing two excess
3083 loops. The lists are created now inside one loop.
3085 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * silc_server_remove_channel_user checks now also global list
3088 for channel and client.
3090 * silc_server_new_channel_user checks now both local and global
3091 list for channel and client. Fixed a bug in client id decoding.
3092 Used to decode wrong buffer.
3094 * silc_server_channel_message checks now both local and global
3095 list for channel entry.
3097 * Tested channel joining (hence JOIN) in router environment
3098 successfully. Tested with two routers, two servers and two
3101 * Tested channel message sending in router environment successfully.
3103 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3105 * Added silc_server_save_channel_key into server.[ch] to save the
3106 received channel key in Channel Key payload processing. It is
3107 also used in JOIN command reply handling.
3109 Equivalent function silc_client_save_channel_key added into
3110 client.[ch] into client library.
3112 * Changed JOIN command reply to send information whether the channel
3113 was created or not (is existing already) and the channel key
3114 payload. Changed protocol specs accordingly.
3116 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3117 the request was sent by ID and not by nickname. Crashed on
3120 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3122 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3123 now correctly save the received data.
3125 * silc_server_free_sock_user_data now notifies routers in the
3126 network about entities leaving the network.
3128 At the same time implemented functions silc_server_remove_id
3129 and silc_server_send_remove_id to receive and send REMOVE_ID
3130 packets. The packet is used to notify routers in the network
3131 about leaving entities. The ID removed will become invalid in
3134 * Added function silc_idlist_del_server into server. Removes and
3135 free's server entry from ID list.
3137 * silc_server_private_message function now checks, if we are router,
3138 that the destination ID really is valid ID, naturally.
3140 * In router when NEW_ID packet is received (for new client) the
3141 hash of the Client ID is saved in the ID Cache but the
3142 client->nickname is set to NULL, instead of putting the hash
3145 IDENTIFY command now also checks that client->nickname must be
3146 valid. If it is not if will request the data from the server who
3147 owns the client. Added new function
3148 silc_server_command_identify_check.
3150 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3151 to set the command to already allocated Command Payload.
3153 * Tested private message sending in router environment with two
3154 routers, two servers and two clients. Fixed minor bugs and now
3157 * Fixed segfault from client's NAMES command. Used to crash if
3160 * Forwarded packets must not be routed even if it is not destined
3161 to the receiver. Changed server code comply with this.
3163 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3165 * Added `require_reverse_mapping' boolean value to ServerParams
3166 structure. If TRUE (not default) the server will require that
3167 the connecting host has fully qualified domain name.
3169 If the reverse mapping is not required and hostname could not be
3170 found the IP address is used as hostname.
3172 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Implemented version string checking to both client and server.
3175 The check is incomplete currently due to the abnormal version
3176 strings used in development version of SILC.
3178 * Changed all command functions in server to use the new
3181 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3183 * Changed char *data to unsigned char *data in ID Cache system to
3184 support binary data as ID Cache data. Changed code to support
3185 binary data in lib/silccore/idcache.c.
3187 * Renamed silc_server_packet_relay_command_reply to
3188 silc_server_command_reply as it is normal packet receiving
3189 function. Rewrote the function to accept command replys for
3190 servers and not only for clients.
3192 * Mark remote router always as registered server if we are connecting
3193 to it. Otherwise, commands sent by the router to us are ignored.
3195 * All ID List find routines now returns the ID Cache Entry pointer
3196 as well if requested.
3198 * WHOIS command works now in router environment, tested with two
3199 routers, two servers and two clients.
3201 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3202 in router environment (as it is almost equivalent to WHOIS) but
3203 hasn't been tested thoroughly. Added new functions:
3205 silc_server_command_identify_parse
3206 silc_server_command_identify_send_reply
3207 silc_server_command_identify_from_client
3208 silc_server_command_identify_from_server
3210 * Disabled route cache adding because adding two different ID's with
3211 same IP replaces the old cache entry thus giving wrong route.
3212 The entry->router->connection is always the fastest route anyway
3213 so route cache may not be needed. Of course, new routes maybe
3214 established after receiving the ID when the entry->router->connection
3215 might not be anymore the most optimal.
3217 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Add route cache for received ID for fast routing.
3221 * Added silc_server_packet_route to route received packet on router
3222 that is not destined to us.
3224 * Renamed silc_server_get_route to silc_server_route_get.
3226 * Added id_string and id_string_len fields into SilcServer to
3227 include encoded ServerID for fast comparing without excess
3228 encoding of the ID's.
3230 * Cleaned up WHOIS command on server side. Added following static
3233 silc_server_command_whois_parse
3234 silc_server_command_whois_check
3235 silc_server_command_whois_send_reply
3236 silc_server_command_whois_from_client
3237 silc_server_command_whois_from_server
3239 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3240 arguments in command replies. All command functions should be
3241 updated to use this macro.
3243 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3245 * Minor typo fixes on command reply handling on server.
3247 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Added silc_server_command_add_to_channel internal routine to add
3250 the client to the channel after router has created the channel and
3251 sent command reply to the server.
3253 * Added generic silc_server_send_command to send any command from
3256 * Use static buffer with ID rendering instead of duplicating data.
3258 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Fixed a channel user mode bug when joining to a channel server gave
3261 everybody channel founder rights, oops.
3263 * We mark ourselves as the router of the incoming server connection
3264 if we are router ourselves. This way we can check in some packet
3265 sending functions whether it is locally connected server. For
3266 incoming router connections we put NULL.
3268 * For router sending packets locally means now always sending the
3269 packet cell wide; to local clients and local servers. For normal
3270 server sending packet locally means sending it to only local
3273 * Fixed the JOIN command to really work in router environment. If the
3274 channel is created it is always created by the router. Router is
3275 also responsible of making the initial joining to the channel,
3276 sending JOIN notify to the sending server and distributing
3277 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3278 does not exist server doesn't do anything else but forward the
3279 command to the router which performs everything.
3281 * Added silc_server_send_channel_key function to send the Channel Key
3284 * Added silc_server_create_channel_key to create new channel key. The
3285 channel key is now re-generated everytime someone joins or leaves
3286 a channel, as protocol dictates. Note: channel->key_len is the
3289 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3292 packet_receive.[ch] to separate packet sending and receiving
3293 routines. The server.[ch] now includes everything else including
3294 actual packet processing (writing and reading data) and other
3297 Renamed silc_server_private_message_send_internal to
3298 silc_server_send_private_message. The routine is still though
3299 used only to relay private messages as server does not send
3300 private messages itself.
3302 Renamed silc_server_new_channel to silc_server_create_new_channel
3303 and added new function sicl_server_new_channel that handles the
3304 incoming New Channel packet. Added also new sending function
3305 silc_server_send_new_channel to send New Channel Payload.
3307 * Added new function silc_server_notify to process incoming notify
3308 packet to the server/router. Server may then relay the notify
3309 to clients if needed.
3311 * Added new function silc_server_new_channel_user to process incoming
3312 New Channel User packet. Router will redistribute the packet and
3313 send JOIN notify to its local clients and locally connected servers
3314 if needed. Normal server will send JOIN notify to its local client
3315 on same channel when received this packet. Added also corresponding
3316 sending function silc_server_send_new_channel_user to sent the
3319 * Added boolean route argument to send_notif_to_channel and
3320 packet_send_to_channel functions to attempt to route the packet
3321 if it is TRUE and send only locally if it is FALSE.
3323 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * silc_server_replace_id now broadcasts the received replace ID
3326 packet if it is not broadcast packet already. The router must
3327 broadcast to inform other routers about changed ID.
3329 * Added backpointer to server's router into SilcServer context in
3330 silcd/server_internal.h.
3332 * Fixed silc_server_packet_broadcast to send correct broadcast
3335 * The channel key is now distributed to the local client as soon
3336 as it is received from the router (in router environment) so that
3337 no other packet may be sent for the channel until client has
3340 * silc_server_remove_channel_user now broadcasts the received
3341 Remove Channel User packet if it is not broadcast packet already.
3342 The router must broadcast to inform other routers about removed
3345 * Added users field into SilcPacketContext that is a reference count
3346 of the context. One can increase the reference count by calling
3347 silc_packet_context_dup which is now changed to just increase the
3348 reference count instead of duplicating the data. The reference
3349 count is decresed by calling silc_packet_context_free that will
3350 free the data after the reference count hits zero.
3352 For now on the packet context and everything allocated into it
3353 (including the raw packet from network) must be freed by calling
3354 the new silc_packet_context_free function. Added also new function
3355 silc_packet_context_alloc that must be used now to allocate the
3356 context. This also means that if a routine is asynchronous from
3357 silc_[client/server]_packet_parse_type the packet context must
3358 be duplicated by calling silc_packet_context_dup. Otherwise it
3359 gets free'd after silc_[client/server]_packet_parse_type returns.
3360 Also, one must remember that if packet is duplicated then its
3361 reference count must be decresed by calling the free function as
3362 many times as it was duplicated.
3364 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3365 from both client and server.
3367 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Made joining to a channel working in router environment.
3371 * Cleaned up JOIN command on server side and create function
3372 silc_server_command_join_channel internal routine to make the
3375 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3377 * Changed silc_command_pending list to SilcDList. Also, added
3378 `ident' field to SilcServerCommandPending structure to identify
3379 the reply and to call correct callback.
3381 Added silc_server_command_pending_check function to replace the
3382 corresnponding macro. The silc_command_pending list is not
3385 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3386 to set identifier to previously allocated Command Payload. It
3387 is used to set identifier for command when resending Command
3390 * Added silc_command_payload_encode_payload to encode Command
3391 Payload buffer from SilcCommandPayload structure.
3393 * Added silc_argument_payload_encode_payload to encode Argument
3394 payload buffer from SilcArgumentPayload structure.
3396 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * Changed WHOIS command to support router connection on server side.
3399 The whois request is always sent to router unless the server is
3400 standalone server. After server has received the reply from the
3401 router will it send the reply to the client.
3403 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3404 broadcast received broadcast packet. The function is used only
3405 by router. The broadcast packet is always sent to the router's
3408 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3409 render given ID to printable string, for log files for example.
3411 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3413 * Made basic router to router connections working. At least they
3414 can now connect to each other but nothing really works the way
3415 they are supposed - yet.
3417 * Added new initiator token to RouterConnection configuration
3418 file in silcd/serverconfig.[ch]. It is used to tell whether we
3419 are the initiator to the remote router or whether we'll expect
3420 the other end to connect.
3422 * Moved registering of listener task to silc_server_init, hence
3423 the server starts listenning as soon as it is run, even if it
3424 does not have connections to other routers. Let's see how well
3427 * Changed default connection retry timeouts for more suitable in
3430 * Removed cipher and such arguments from silc_idlist_add_client
3431 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3432 Added new function silc_idlist_add_data to add the keys and stuff
3435 * Added SilcIDListData structure and added it to SilcClientEntry
3436 and SilcServerEntry as their first field in the structure. This
3437 way we can explicitly cast the ID entries to the SilcIDListData
3438 structure and get common data for the entries. In past, we had
3439 to first check what type of connection it is and then cast it to
3440 correct ID entry type. Now, we can directly cast the opaque
3441 pointer to the SilcIDListData (no matter what ID entry it actually
3442 is) and get the data needed.
3444 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3447 in some circumstances even if threre were timeout tasks, though not
3448 IO tasks, but tasks anyway. Now fixed.
3450 * Defined SilcServerConnection structure to hold connection specific
3451 stuff about directly connected servers and routers. The definition
3452 is currently in silcd/server_internal.h. I thought about having
3453 a bit more important role fro this struct but for now it is used
3454 only when connecting to other server (or router actually).
3456 * Added connecting retry support in server when connecting to
3457 router(s). The retry feature implement exponential backoff
3458 algorithm. Also, added SilcServerParams structure to hold default
3459 parameters for server. For now, it include these retry settings
3460 and are hard coded. After server is moded to be as Silc Server
3461 Library this structure will be more important.
3463 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3465 * Changed client librarys channel->clients table to SilcList and
3466 changed code accordingly.
3468 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Changed client's channel table to SilcList and changed code
3471 accordingly. Also changed SilcChannelClientEntry to include back-
3472 pointer to the channel so that client entry can use that structure
3473 as list as well and we have fast cross-reference to the channel.
3474 This change dramatically decreased the complexity of channel
3475 handling with client entry and vice versa (removed one extra
3476 loop when searching for channel entry from many functions).
3478 * Changed server->sim from table to SilcDList and changed code
3481 * NAMES command can now be used from user interface. It will show
3482 the user list on the channel, neatly.
3484 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3485 Code now saves realname of the user if it becomes available.
3487 * Renamed configure.in to configure.in.pre and made ./prepare
3488 script to automatically add correct version string to
3489 configure.in which it creates from configure.in.pre.
3491 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * NAMES command reply now shows users mode with the nickname when
3496 * Moved silc_client_ch[u]mode[_char] functions from
3497 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3498 place sucks, they are utility functions and should be in some
3501 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3503 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3506 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Added TRQ (efficient deque and list library) into lib/trq. This is
3511 a very good list library that is currently used in the SILC. Defined
3512 SilcList API over the library because I didn't like the API very
3513 much. See lib/trq/silclist.h for the API and examples of how to
3514 use the API. Fixed various places in the code to use the new
3515 SilcList API. The SilcList is meant for lists that has a structure
3516 already defined as a list. It is not suitable to add just some
3517 context to the list (in TRQ, the context is the list actually).
3519 So, I defined SilcDList that can be used for the purpose where
3520 predefined list structure does not exit. This can be used as
3521 such list. Now some context just can be added to the SilcDList.
3522 Currently this list is not used in the SILC just yet, though there
3523 are a lot places where this can replace dynamically allocated
3524 tables and I will fix these places, later, to use SilcDList.
3525 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3526 and use TRQ internally).
3528 Also fixed some annoying warning messages that the original TRQ
3529 code generated. Also minor changes to TRQ's Makefile.in.
3531 * Added support for querying by Client ID to both WHOIS and
3532 IDENTIFY commands into server, as required by the protocol.
3534 * Removed method function pointers from SilcBuffer structure. They
3535 weren't used to anything and just increased the context size for
3536 no good reason. This change also made silc_buffer_alloc and
3537 silc_buffer_free functions inline functions.
3539 * Disabled command flooding detection support until it's fixed so
3540 that it accepts commands in but does not execute them more than once
3543 * Added silc_net_localhost(), to return local hostname, into
3544 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3545 that must be initialized before calling silc_client_init.
3547 * Added new function: silc_server_send_notify_on_channels to send
3548 notify messages to all channels client has joined. It is assured
3549 that the message is sent only once per client.
3551 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3552 lib/silcutil/silcutil.[ch] as silc_format function. The new
3553 function is generic and is used by server as well, not only by
3554 the logging routines.
3556 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3557 the provided version string was not acceptable. Added new function:
3558 silc_ske_check_version into lib/silcske/silcske.h. The function
3559 must be implemented by the application (client or server) and it
3560 does not reside in the SKE library. The function checks the version
3561 string remote end sent.
3563 * Added back pointers (to opaque context and to SilcSocketConnection)
3564 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3566 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3567 duplicate packet context structure.
3569 * Changed `notify' client operation to send same arguments as client
3570 receives from server except for ID's. ID's are mapped to correct
3571 ID entry and that is returned. Also, if channel entry is not sent
3572 by server but the notify is for channel the channel entry is sent
3573 to application (otherwise application doesn't know that it is for
3574 channel (library gets it from packet's Destination ID)).
3576 * Added silc_client_remove_from_channels into client library to
3577 remove a client from all channels it has joined to. Used when
3578 received SIGNOFF notify from server. Added also new function
3579 silc_client_replace_from_channels to replace old ID entry with
3580 new ID entry on all channels. Used when received NICK_CHANGE
3583 * Fixed ID Cache list handling in silc_idlist_get_client in
3584 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3585 to get (or query) client by ID.
3587 * Updated TODO list.
3589 * Added connection authentication status message defined by the
3590 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3591 support for these into the code in client and server side.
3593 * Added generic function silc_client_send_command to send any command
3594 with variable argument list. Application should use this function
3595 to send commands if the command functions provided by the library
3596 does not suite for the application's user interface needs.
3598 * Added new `failure' client operation. Application is notified about
3599 received failure packet if client is executing a protocol. In this
3600 case the protocol's execution has failed.
3602 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3603 is required by the protocol.
3605 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3606 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3609 * Added status flag to SilcSKE object to indicate realtime status
3610 of the SKE protocol.
3612 * Application receives now exactly same command reply arguments as
3613 the library receives from server. However, if ID is received the
3614 corresponding ID entry is returned to the application (eg. Client
3615 ID is mapped to correct SilcClientEntry entry and that is returned).
3616 Changed command_reply client operation due to this change.
3618 * Changed all ID's in commands and in command replys as ID Payloads.
3619 Change affected both client and server side codes.
3621 All ID's sent in SILC network (with execption of ID's in SILC
3622 Packet header) are sent in ID Payload to support variable length
3625 * Server now notifies nick changes and notifies all clients on
3626 the channels about the new nickname (about the new Client ID,
3629 * Implemented CMODE command to change channel modes. Supports all
3630 channel modes defined by the protocol specs except ban and invite
3631 lists. (Also, private channel key mode is supported but support for
3632 setting private channel key in client is missing, thus, this mode
3633 has no effect on client side (except that server requires that the
3634 client uses private channel key and normal channel traffic does not
3637 Also, invite mode works per se, but INVITE command does not work
3638 yet correctly, so you can set channel as invite only channel but
3639 inviting clients to the channel does not work (it is yet to be
3640 thought what's the best way to do it).
3642 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3643 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3644 Implemented CUMODE command to change user's mode on the channel.
3645 Supports all modes defined by the protocol specs.
3647 * Added NAMES command reply to return users modes on the channel.
3649 * Removed unnecessary and slow ciphers from lib/silccrypt.
3651 * Set SO_KEEPALIVE option to connection sockets by default.
3653 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3655 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3656 redefined the Notify Payload into protocol specs.
3658 * Added silc_id_payload_parse_id to get ID directly from raw
3661 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3664 accept searching by Client ID as well.
3666 * Added support for LEAVE and SIGNOFF notify types in client library.
3668 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3669 to parse ID Payload from raw data.
3671 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Added flags parameter into silc_ske_assemble_security_properties
3674 function in lib/silcske/silcske.[ch].
3676 * Changed notify client operation to fit better for notify messages
3677 sent by server. The notify payload received from server is now
3678 passed to the application (after parsing it to SilcNotifyPayload).
3679 It is application's responsibility to retrieve the arguments
3680 from the payload and show the message the way it wants. The message
3681 sent by server is implementation specific.
3683 * Changed public keys to comply with the protocol specification.
3684 Old public keys are not supported anymore and are not compatible.
3686 * Removed nickname from Channel Payload as the latest draft removed
3687 it. The client must resolve the nickname from the NAMES command
3688 reply received when it joined the channel.
3690 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3692 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3694 * Fixed some errors in protocol specification drafts.
3696 * Created lib/silccore/silcnotify.c to implement Notify Payload
3697 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3698 generic payloads described by protocol specifications. The file
3699 includes implementations for ID Payload and Argument Payload.
3701 * Changed Command Payload implementation to use the new Argument
3702 Payload. Changed command_xxxx_payload to command_payload_xxxx
3703 to comply with SILC coding conventions.
3705 * Added suppport for Argument Payload handling in Notify Payload
3706 implementation as protocol requires it. Added the new support
3707 into server and client lib as well.
3709 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * Added support for multiple nicknames on same channel. [n] is
3712 added locally to the nickname if there are more than one same
3713 nicknames on the channel.
3715 * Server now sends all nicknames that matched WHOIS request.
3716 Client also shows the list received from server.
3718 * Added TOPIC command to client side. User can now set and show
3719 current topic on channel.
3721 * Added MOTD command to client and server. Also, server sends the
3722 motd when client connects to the server.
3724 * Changed version strings to comply ISO 8601.
3726 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3728 * Fixed protocol error handling in client library. It should now
3729 cope even if the SKE fails for some reason.
3731 * Made new protocol specification drafts for submitting to IETF.
3733 * Implemented TOPIC command to server in silcd/command.c.
3735 * Added two new notify types into lib/silccore/silcnotify.h:
3736 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3737 notify nickname change and topic setting/change on a channel.
3739 * API change of command_reply operation in client library. The
3740 application gets now the status type received from server as well.
3742 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3746 * Cras fixed and optimized the packet handling even further and
3747 it should work now. Minor change to the prototype of function
3748 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3750 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Added new function into lib/silcutil/silcschedule.[ch]:
3753 silc_schedule_with_fd to select() a specified fd. The function
3754 returns after timeout expires or data arrives or goes. The
3755 function is used by packet routines to wait that all data is
3756 received from network.
3758 * Fixed data reading from network in lib/silccore/silcpacket.c.
3759 The code now assures that all data is read from the fd and then
3760 continues packet processing. This was a bug fix since the code
3761 used to drop some data in some circumstances.
3763 * Added new function into lib/silcclient/client.[ch]:
3764 silc_client_start_key_exchange to start key exchange after
3765 connection has been established to server. The code internally
3766 now uses this funtion but its main purpose was to provide it
3767 for applications that perform their own connecting. After
3768 application has created a connection it merely calls this
3769 function to start the key exchange between client and server.
3770 The library takes care of everything else after that.
3772 Updated also lib/silcclient/README to explain the usage of
3775 * Do not send to application information that connection has
3776 been established. Application gets notified it by connect
3779 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3781 * Applied cras's patch to add silc_schedule_one function. The
3782 function runs scheduler once and returns.
3784 * Fixed the scheduler after cras messed it up. The timeout
3785 handling works now as it's supposed to work.
3787 * Added into lib/silccore/ silcnotify.h to include notify
3788 message types support. Changed silc_server_send_notify*
3789 functions, in server.[ch], to support those new notify types.
3790 Added the support for the notify types into client library,
3791 as well. Added new notify client operation into ops.h in
3794 * Changed silc_server_packet_send_to_channel to send normal
3795 packets instead of just channel message packets. The function
3796 is now used to send the notify packets to channels. It is not
3797 used to send channel message packets anymore, as server never
3800 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3801 va_arg()s as it seems to require it nowadays. I guess, if SILC
3802 is compiled with older va_arg() the new code should work anyway.
3804 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3806 * Splitted core library. Core library (lib/silccore) includes
3807 now only SILC protocol specific core (and common) components.
3808 Created new utility library (lib/silcutil) that includes more
3809 generic purpose stuff. The stuff for util library was taken
3810 from the old core library. This was minor and easy split.
3812 * Created SILC Client Library (lib/silcclient) that includes
3813 implementation of the SILC client without user interface. This
3814 was major move from silc/ directory. The code has been changed
3815 so that it is transparent towards the user interface. The
3816 silc/ directory includes now the same user interface as before
3817 and it uses the new client library. Read lib/silcclient/README.
3818 Basicly, the client library performs everything else related
3819 to SILC except user interface handling. Also, configuration
3820 files are considered to be part of user interface and library
3821 does not handle them.
3823 This change also changed a lot of structures, function naming etc.
3824 Most important change was that SilcClientWindow object was
3825 renamed to SilcClientConnection in the client library. Created
3826 also new file lib/silcclient/ops.h. Also added new files
3827 silc/local_command.[ch] and silc/client_ops.[ch].
3829 All these changes were made to make it easier for user interface
3830 designers to create what ever user interface for the SILC client
3833 It is also expected that the server will be moved to lib
3834 directory as well and SILC Server Library will be created;
3835 sometimes in the future.
3837 * Removed Local commands from lib/silccore/silccommand.h as
3838 they are application specific and new client library does not
3839 handle any of those anymore.
3841 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3842 old client implementation in silc/.
3844 * Added support for callback functions in SILC_LOG_* macros.
3845 Application can now set its own callbacks that will be called
3846 instead of using the default functions that will always print
3847 the debug messages to stderr (or stdout). Also, debugging can
3848 now be disabled by setting silc_debug to FALSE and re-enabled by
3849 setting it to TRUE. Note, that logging will still work even
3850 if debugging is disabled.
3852 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3853 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3854 silc_log_reset_debug_callbacks.
3856 * To enable debugging in silc client one must give now -d
3857 option on command line.
3859 * Changed silc_schedule_init to automatically allocate task queues
3860 if they are not allocated before calling it.
3862 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Added GMP 3.1 into math library.
3866 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3868 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3869 a channel in SILC network. The packet is used by servers and
3870 routers to notify other routers that user has left a channel.
3871 This little feature was missing until now. Added the feature
3872 to protocol specification as well.
3874 Added functions: silc_server_send_remove_channel_user and
3875 silc_server_remove_channel_user into server.[ch].
3877 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3878 lib/silccore/silcpacket.h. However, they are not implemented
3881 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * Fixed joining to a channel and sending channel messages
3884 between server and router. The channel message sending should
3885 now work inside a cell.
3887 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Fixed the private message sending between server and router.
3890 The private message sending should now work inside a cell.
3892 * Added silc_server_replace_id into server.[ch] to replace
3893 existing ID in the SILC network.
3895 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3896 and silc_idlist_replace_server_id into idlist.[ch] in server.
3898 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * Fixed the server to server connections. Server can again now
3901 connect to router. Router to router connections probably does
3904 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3906 * Added dynamic protocol registering support. Now protocols can
3907 registered and unregistered on the fly. Patch by cras.
3909 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * Added lib/contrib directory to hold routines that some platforms
3912 don't have but are needed by SILC.
3914 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3915 into lin/contrib to provide getopt() and getopt_long() for
3916 those who don't have it.
3918 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Added AWAY command to client. When away message is set and
3921 client receives a private message packet the client automatically
3922 replies to the sender with the away message.
3924 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3925 bug seemed to be the cause of recent problems when compiling
3928 * Added version detection support to SKE protocol specification
3929 and added the new changes to the SKE implementation as well.
3930 There were other minor changes in the SKE protocol as well.
3932 Many changes in lib/silcske/silcske.[ch] and in
3933 lib/silcske/payload.[ch].
3935 * Added ^U functionality, clear input line. Patch from cras.
3937 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * Mainly small bugfixes on core library. Fixed some debugging
3940 logging and buffer overflow in silclog.c.
3942 * Updated config.sub and config.guess on the distribution tree.
3944 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3946 * Added command lagging support in server. Client may execute
3947 commands now only once in two seconds.
3949 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3951 * Optimized packet reception. MAC computation and checking is now
3952 also more optimized. A lot previously duplicated code is now
3953 used as generic by both client and server.
3955 * Fixed key pair generation in clientutil.c
3957 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3959 * Added into lib/silccore/silcbufutil.[ch] new function;
3960 silc_buffer_realloc.
3962 * Moved generic packet sending/encryption functions to
3963 lib/silccore/silcpacket.[ch] from client and server. Some
3964 rewriting of the functions.
3966 * Moved all generic packet reception/decryption functions to
3967 lib/silccore/silcpacket.[ch] from client and server. The
3968 packet processing is now much cleaner in both client and server.
3969 These were major changes in both client and server.
3971 * Created many common functions in server to do packet sending.
3972 Previously code were duplicated a lot, this has been removed
3975 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3977 * Rewrote major parts of the ID cache system. Don't know
3978 whether it is better now or not but at least the API is more
3981 * Major rewrite on ID cache stuff on client because of the ID
3982 cache API changes. Added idlist.c to client.
3984 * Also major rewrite on ID cache stuff on server as well.
3985 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3986 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3987 in hand, instead they are all put into the ID cache system now.
3988 All server_idlist_* routines uses ID cache now instead of
3989 traversing its own lists (those lists does not exist anymore).
3990 SilcIDList though still exists. Also, SilcXXXEntry's are
3993 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * Finally made the SKE implementation compliant to the protocol
3996 specification. All mp integers are now binary encoded as
3997 opposed being HEX encoded.
3999 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4002 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4003 functions: silc_[encode/decode]_pem. Also added function
4004 silc_encode_pem_file to PEM encode with newlines ('\n') for
4007 * SILC public keys are now encoded either PEM or binary. Same
4008 option is for private keys as well. By default private keys
4009 are binary encoded and public keys PEM encoded. Silly HEX
4010 encoding were removed.
4012 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4013 function to create fingerprints.
4015 * Fixed a bug in SHA1; does not change the original data anymore.
4017 * Partly implemented INFO command on client and server side.
4018 Fixed CLEAR command. Changes to SERVER command; show current
4019 server(s) when giving command without arguments. Added
4020 VERSION command to client.
4022 * Added check to server that unregistered connections cannot
4023 execute commands (unless it is specificly allowed).
4025 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Fixed screen refresh.
4029 * Fixed channel joining bug from client. On some circumstances
4030 client tried to join to a channel it had already joined.
4032 * Added public key verification process into client's protocol.c.
4033 The client now verifies the public key from user and saves
4034 it into ~./silc/serverkeys/ directory.
4036 Added into: clientutil.[ch]: silc_client_verify_server_key.
4038 * Changed SKE protocol's silc_ske_initiator_finish function
4039 to accept callback function that verifies the received public
4040 key. Removed old silc_ske_verify_public_key function.
4042 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4045 silc_pkcs_private_key[_data]_set.
4047 * Made the password and public authentication more cleaner in
4048 server's protocol.c.
4050 * Removed historic and obsolete protocol `channel_auth' from
4051 both client and server.
4053 * Removed wrong way of sending command status messages from
4054 server to client in server's command.c. The old way violated
4055 protocol specification.
4057 Changes to silccore/silccommand.[ch]: removed
4058 silc_command_encode_status_payload -> not needed anymore,
4059 changed silc_command_encode_payload_va to accept extra
4060 argument on variable argument list. The argument type must
4061 now be provided to the function. Also, added new function:
4062 silc_command_encode_reply_payload_va which is same as
4063 normal command_encode_payload_va except command status type
4064 is provided as extra argument.
4066 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Added ~./silc directory handling. The directory includes the
4069 public and private keys for the client.
4071 Added silc_client_check_silc_dir, silc_client_create_identifier
4072 and silc_client_load_keys.
4074 * Implemented SILC protocol compliant public key. Added public
4075 and private key saving to and loading from files.
4077 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4078 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4079 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4080 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4081 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4083 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4084 silc_pkcs_load_[public/private]_key.
4086 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Added silc_server_get_route (route.[ch]) to get connection
4089 data for the fastest route for given ID.
4091 * Implemented INVITE command on client and server. The command
4092 were re-defined in the SILC Protocol Specification and the
4093 implementation now complies with the specification.
4095 * Implemented PING command on client and server.
4097 * Implemented NAMES command on client and server. The server side
4098 supports currently only normal server not router server yet.
4099 Some changes to NAMES definition in SILC protocol specification.
4101 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Implemented LEAVE command on client and server.
4105 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4106 again. This change was made to the protocol as well. Server
4107 should not violate the protocol specification anymore.
4109 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4112 was tested. SOCKS4 was not but should work anyway.
