3 * Fixed the silc_parse_command_line to remove extra spaces
4 from the start and end of the arguments. Affected file is
5 lib/silcutil/silcutil.c.
7 * Cancel and free any active protocol in the function
8 silc_server_close_connection. Affected file silcd/server.c.
10 * Cancel and free any active protocol in the function
11 silc_client_close_connction. Affected file is
12 lib/silcclient/client.c.
14 * Do not execute the KILL command for clients that are in
15 history (ie. they are not in the network). Affected file is
18 * Fixed KILL notify handling, client does not crash anymore.
19 Affected file irssi/src/silc/core/silc-channels.c.
21 * Reduced the default packet buffer size from 2048 to 1024 in
22 lib/silccore/silcpacket.c.
24 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
25 counter to the SKE context that is incresed when the SKE library
26 performs async operation outside the library. If the outside
27 process frees the SKE context and FREED status will be set
28 and the library will detect after the sync operation that the
29 libary is freed. The affected files are
30 lib/silcske/silcske[_status].[ch].
32 * Resolve the client entry information in the function
33 silc_client_channel_message to assure that NULL pointer is not
34 passed as client entry to the application. */
36 * Fixed the task timeout calculation to assure that there is
37 never negative timeouts. The affected file is
38 lib/silcutil/silcschedule.c.
40 * Fixed the channel user mode notification sending in server.
41 It was sent point-to-point to the router (or to server by router)
42 but it needs to be destined to a channel. The routines now
43 supports sending the channel user mode notifys to the channels
44 when announcing clients and channels. Affected files are
45 silcd/server.c and silcd/packet_receive.c.
47 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
48 It did not actually replace the old channel entry in the cache.
49 Affected file lib/silcclient/client_notify.c.
51 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
53 * Fixed a possible crash in silc_packet_send_prepare. It now
54 assures always that there is enough space in the buffer and
55 at the tail area of the buffer (for MAC).
57 Fixed the inbound buffer reallocation in silc_packet_read.
58 It was old code and did not handle the reallocation correctly.
61 The affected file is lib/silccore/silcpacket.c.
63 * Fixed buffer overflow in silc_parse_nickname in the file
64 lib/silcutil/silcutil.c.
66 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
68 * make install generates new server keys only if there is not
71 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
73 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
74 Added check that if the NOREPLY is set then we will not send
75 the away message. This avoids infinite loop of away messages
76 if both clients are away. The affected file is
77 lib/silcclient/client_prvmsg.c.
79 * Fixed client crash if /NICK was given without arguments.
80 Affected file lib/silcclient/command.c.
82 * Server does not send the invite list in INVITE command back
83 to the client if the list was not altered. Added this notion
84 to the protocol spec as well. Affected file silcd/command.c.
86 Fixed possible crash in INVITE command by checking the
87 value of silc_server_get_client_route command.
89 * Fixed the INVITE notify type handling. The arguments are now
90 taken in correct order and client does not crash. The affected
91 file is irssi/src/silc/core/silc-channels.c.
93 Removed the "Inviting xxx to channel" message from the
94 client library away and let the application handle it.
95 Affected file lib/silcclient/command.c. Added that message
96 to Irssi SILC client's message formats.
98 * Fixed CMODE command crash in client. It now checks the
99 amount of arguments correctly and does not crash. The affected
100 file is lib/silcclient/command.c.
102 * Do not create new channel automatically in silc_channels_join
103 but check whether the channel by that name already exists.
104 Affected file irssi/silc/core/silc-channels.c.
106 * Do not send the SERVER_SIGNOFF to router if the disconnected
107 entity was the router. Affected file silcd/server.c.
109 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
110 SILC client as it was missing from there.
112 Added the handling of the KICK notify to the Irssi SILC client
113 as it was missing. Added "you have been kicked" message to
114 Irssi SILC client's message modules formats.
116 Added the handing of the KILL notify to the Irssi SILC client
117 as it was missing. Added the kill message module formats
120 The affected file is irssi/src/silc/core/silc-channels.c.
122 * The router did not save the channel mode the server announced.
123 Affected file silcd/packet_receive.c.
125 * Fixed a possible crash in INFO command in server. If the
126 server did not provide the server info it crashed. Affected
127 file silcd/command.c.
129 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
131 * Fixed the GETKEY command in the server to check also the
132 global list. Otherwise the GETKEY would not work correctly
133 in normal SILC server. Affected file silcd/command.c.
135 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
137 * Fixed GETKEY crash, it crashed if the command did not succseed.
139 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
142 is now real and not just an macro interface to GMP.
144 Removed the entire GMP from the source tree and imported new
145 NSS MPI library instead. Reason for removing GMP is that it is
146 extremely large and compiles extremely slow. The NSS MPI
147 is only a few files and compiles in less than 10 seconds.
148 The speed is also about the same as GMP. The MPI is imported
151 If the system has GMP installed we will still use the GMP.
152 If it is not then the NSS MPI will be compiled.
154 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
156 * Merged a long nickname (127 characters long) crash bugfix from
157 Irssi CVS tree. Affected file irssi/src/core/misc.c.
159 * Merged a freed memory reference bugfix from Irssi CVS tree.
160 Affected file irssi/src/core/commands.c.
162 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
164 * Added the server's public key sving and verification to the
165 server when performing the SKE. This was missing and the
166 remote server's (or router's) public key was accepted without
167 checking whether we have it previously or trust it at all.
168 Affected file silcd/protocol.c.
170 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
172 * Check in the silc_server_timeout_remote if protocol is active
173 and make sure that the protocol's final callback is called so
174 that all memory if freed. Affected file silcd/server.c.
176 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
178 * silc_server_whois_send_reply crashed the server if the nickname
179 was 127 characters long. Affected file silcd/command.c.
181 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
183 * Added sanity check to the silc_server_new_client. If the hostname
184 is provided inside username then check that the provided hostname
185 really is the same as the resolved one. If the hostname was not
186 resolved then check it from the public key. Affected file is
187 silcd/packet_receive.c.
189 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
190 if the server disconnected us and the connection is not valid
191 anymore. Affected file irssi/src/silc/core/silc-channels.c.
193 * Moved the silc_client_[chmode|chumode|chumode_char] away from
194 the library to the lib/silcutil/silcutil.[ch].
196 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
198 * Close log file after open. Affected file
199 lib/silcutil/silclog.c.
201 * Check whether sock == NULL in silc_client_send_packet and return
202 if it is. Affected file lib/silcclient/silcclient.c.
204 * Check rec->entry == NULL in the Irssi SILC Client before
205 sending the channel message. Affecte file is
206 irssi/src/silc/core/silc-servers.c.
208 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
210 * Merged a splitted window bugfix from Irssi CVS tree. The
211 affected file is irssi/src/fe-text/textbuffer-view.c.
213 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
214 It did not print nickname.
216 * Improved the distributions system a bit.
218 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
220 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
221 irssi/src/fe-text/gui-window.c.
223 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
224 to in-active server. The affected file is
225 irssi/src/silc/core/client_ops.c.
227 * Resolve the client in USERS command reply if the entry does
228 not have username resolved. The affected file is
229 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
230 command to WHOIS command to really resolve stuff. The USERS
231 is not used any more in any critical section so WHOIS can
232 be used even though it might be slower than IDENTIFY.
234 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
237 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
239 * Changed the protocol API a bit more consistent in the
240 lib/silccore/silcprotocol.[ch].
242 * Changed the following headers to ROBODoc format:
244 lib/silccore/silcpayload.h
245 lib/silccore/silcprotocol.h
246 lib/silccore/silcsockconn.h
248 All core library headers are now formatted.
250 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
252 * Fixed a bug in Irssi SILC client; do not show that you are
253 server/router operator if you really are not. Affected file is
254 irssi/src/silc/core/client_ops.c.
256 * Renamed silc_command_free_payload to silc_command_payload_free.
257 Affected file lib/silccore/silccommand.h
259 * Added silcmath.h to include the prototoypes of various routines
260 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
263 * Changed the following headers to ROBODoc format:
265 lib/silccore/silcchannel.h
266 lib/silccore/silccommand.h
267 lib/silccore/silcid.h
268 lib/silccore/silcidcache.h
269 lib/silccore/silcmode.h
270 lib/silccore/silcnotify.h
271 lib/silccore/silcpacket.h
272 lib/silcmath/silcmath.h
274 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
276 * Added checking to the server code not to start the server if
277 ciphers and stuff are not configured properly. Affected files
278 silcd/serverconfig.[h] and silcd/server.c.
280 * Changed the layout of the header files of the public interfaces
281 in the SILC libraries. The new layout supports ROBODoc
282 documentation tool (and some others) so that it is easy to create
283 a library reference manual. All the other headers and source
284 code must still follow the CodingStyle document. Also source
285 code must not include these ROBODoc stuffs, only the headers.
286 Furthermore, all public interface headers must now be named
287 by using `silc' prefix, example: silcapi.h, silccipher.h.
288 Some files were renamed due to this. All the other headers
289 must not be used as public interfaces. I will update the
290 CodingStyle document later. Changed following headers, so far:
292 lib/silcclient/silcapi.h
293 lib/silccore/silcauth.h
294 lib/silccore/silcprivate.h
295 lib/silccrypt/silcdh.h
297 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
301 * Removed silc_client_packet_send_flush from the client library
302 as it is not needed. Affected file lib/silcclient/client.[ch].
304 * Added printing of message of unresolved authentication method
305 to the Irssi SILC client. Added it to the module formats.
306 Removed the same message from the client library.
308 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
310 * Added new distribution feature, DISTLABEL. Every distribution
311 can define own preprocessor label that can be used in the
312 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
313 file distributions, acconfig.h.pre and prepare.
315 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
317 * Added Makefile.defines_int to include the actual definitions
318 for Makefile.defines.in. Tested the new distribution system,
319 created distributions and tested installation.
321 * Added AWAY message printing to the Irssi SILC client. Added
322 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
324 * Added SCONNECT command to call the SILC's CONNECT command.
325 Cannot use CONNECT directly since Irssi uses that internally.
326 Affected file irssi/src/silc/core/silc-servers.c.
328 Added ACTION local command. It is same as ME command but takes
329 the channel as mandatory argument.
331 Rewrote some of the Irssi's help files to suite for SILC
334 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
336 * Added Makefile.defines[.in] that should for now on be included
337 in all Makefile.am file in the source tree. That file includes
338 all common compilation definitions for SILC source tree.
340 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
342 * Minor changes to the ./prepare script to change the package
343 name according the distribution name to the configure.in.
345 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
347 * Created new distribution system. Added file `distributions'
348 that defines all the distributions that can be created out of
349 the SILC source tree. The ./prepare script now reads that
350 file to determine how to prepare the distributions. The
351 first argument to the ./prepare is the name of the distribution
352 and second is the version of the distribution. If given
353 without arguments it creates the default (toolkit) distribution
354 with the default version (defined in ./prepare).
356 All Makefile.am files that are subject to the distributions
357 are now named as Makefile.am.pre. These are ./Makefile.am
358 and lib/Makefile.am. Others may be changed later.
360 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
362 * Added invite list, ban list, some key management and connection
363 error message printing to module formats in the Irssi SILC client.
365 * Added new silc_client_set_away_message to set the away message
366 that is back to the person who sent private message. The
367 affected file lib/silcclient/silcapi.h and the
368 lib/silcclient/client_prvmsg.c.
370 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Fixed the private message sending in the Irssi SILC client,
373 added local command KEY to the Irssi SILC client.
375 Added key management and key agreement message formats to the
376 irssi/src/fe-common/silc/module-formats.[ch].
378 Added USERS (alias WHO) printing, server/router operator
379 indication and LIST command printing to the module formats.
381 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
383 * Fixed channel joining notify handling, cumode notify handling
384 from Irssi SILC client.
386 * Added SILC specific module-formats to the Irssi SILC client so
387 that SILC specific message hilighting, colors etc is possible.
388 Affected file irssi/src/fe-common/silc/module-formats.[ch].
390 Added channel mode, channel user mode, actions, notices,
391 whois and whowas printing to the the module-formats.c.
393 * Fixed a bug in channel deletion in the server. The channel
394 is not left to the cache even if the channel founder auth mode
395 is set when there are no users anymore on the channel. Affected
398 * The silc_net_localhost now resolves the entire hostname including
399 the domain name. Affected file lib/silcutil/silcnet.c.
401 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
403 * Changed the ask_passphrase client operation to be ascynchronous.
404 It has now a completion callback and a context that the
405 application must call after it has got the passphrase from
406 the user. Affected files lib/silcclient/silcapi.h,
407 lib/silcclient/protocol.c, lib/silcclient/command.c and
410 Added SilcAskPassphrase callback that the application calls
411 to deliver the passphrase to the library.
413 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
414 The public key verification and especially a certificate
415 verification is asynchronous procedure.
417 Added new SILC_SKE_STATUS_PENDING status to indicate the
418 request is pending and a callback will be called to finalize
421 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
422 indicate that remote end did not send its public key (or
423 certificate), even though we require it. Added check for this
424 condition in the SKE. This was a security bug, now fixed.
426 Defined new SilcSKEVerifyCbCompletion callback that is called
427 when the verification process is completed.
429 The affected files lib/silcske/silcske_status.h and
430 lib/silcske/silcske.[ch].
432 * Changed the verify_public_key client operation to be async
433 as well. Defined SilcVerifyPublicKey callback that is used to
434 indicate the success of the public key verification process.
436 Changed the server and client to use the new async client
439 * Changed the Irssi SILC client's internal scheduler to be called
440 twice as many times as it used to be. As a result the client
441 should be a bit faster now. Affected file is
442 irssi/src/silc/core/silc-core.c.
444 * Added support to Irssi SILC client of asynchronous public key
445 verification and passphrase inquiry. Affected file is
446 irssi/src/silc/core/silc-core.c.
448 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Do not say "You have left channel %s" in client library.
451 Moved it to the application. Affected files are
452 lib/silcclient/command.c and silc/client_ops.c.
454 * Fixed silc_client_get_clients. Command context was not
455 duplicated and was freed memory in the callback. Affected
456 file lib/silcclient/idlist.c.
458 * Do not say "you are now talking..." on JOIN command in the
459 client library. The appliation must handle it.
461 * Do not say ".. changed topic to" in command reply in the
462 client libary. The application must handle it.
464 * Fixed TOPIC command sending in the client library.
466 * Fixed a memory leak in silc_client_command_free in the file
467 lib/silcclient/command.c.
469 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
471 * Imported a modified version of Irssi client to the source tree.
472 The Irssi will be used to create a new client called
473 Irssi SILC. Imported to irssi/.
475 Added silc_core_init_finish function to the Irssi. Affected
476 file irssi/configure.in.
478 A lot changes in the Makefile.ams around the irssi tree.
480 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
482 * Do not rehash if the new size is same as the old size of the
483 hash table, in the silc_hash_table_rehash*. The affected file
484 lib/silcutil/silchashtable.c.
486 * Replaced hash_table_del_by_context calls from the server
487 (when channel->user_list and client->channels) to the
488 hash_table_del as it is sufficient and faster.
490 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
492 * Added silc_hash_table_list, silc_hash_table_get and the
493 SilcHashTableList structure to provide an alternative way to
494 traverse the hash table. The affected files are
495 lib/silcutil/silchashtable.[ch].
497 * Changed the server's idlist routines to use the hash table
498 routines to optimize the code.
500 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
502 * Replaced the client entry's `channel' list and channel entry's
503 `user_list' list to hash tables for optimized lookup. Changed
504 the code to use the hash table interface around the code.
505 Affected file lib/silcd/idlist.[ch].
507 * Added `auto_rehash' boolean argument to the function
508 silc_hash_table_alloc to indicate whether the hash table should
509 auto-rehash when it thinks is appropriate time. It will
510 increase the hash table size if the there is twice as much
511 entries in the table than the size of the table, and will
512 decrease the size if there are twice as less entries than
513 the size of the table.
515 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
517 * Fixed silc_xxx_get_supported to not crash at some circumstances.
519 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * silc_idcache_purge_by_context deletes the entry now by context
522 as it is supposed to do. Affected file lib/silccore/idcache.c.
524 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
525 client is not anymore valid (WHOWAS givens the info) and not
526 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
528 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
530 * Removed the `data' and `data_len' arguments from the ID Cache
531 interfaces and added `name' argument. ID Cache does not handle
532 anymore the binary data only a names associated with given ID.
534 * When hashing a Client ID with silc_hash_id the entire ID is
535 not hashed anymore, instead only the hash of the Client ID is
536 hashed. This way we can access the Client ID from the cache
537 with Client ID but with the hash of the ID (which is a hash of
538 the nickname) as well without any difference in performance.
540 Added also silc_idcache_find_by_id_one_ext to do one on one
541 searching when we have the actual ID. Added also function
542 silc_hash_client_id_compare. The affected files are
543 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
545 * When hashing the name associated with a ID it is always done
546 in lowercase. This way we can access the cache without worrying
547 about case-sensitivity, even though, for example nicknames are
550 * Fixed a bug in server with channel message sending. It put
551 wrong ID type as destination ID. The affected file
554 * silc_idcache_del_by_context now deletes from all hash tables
555 by context. Affected file lib/silccore/idcache.c.
557 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Changed the client library to use the new ID Cache interface.
560 Changes around the source tree.

566 hash table. Affected file lib/silcutil/silcutil.[ch].
568 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
570 * Added new function silc_idcache_del_by_context into the
571 lib/silccore/idcache.[ch].
573 * Changed the server's ID list routines to use the new ID Cache
574 interface. Changes around the source tree.
576 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
578 * Added silc_hash_table_del[_by_context]_ext functions in to the
579 lib/silcutil/silchashtable.[ch].
581 Removed silc_hash_table_find_all* routines and added new
582 silc_hash_table_find_foreach to replace them.
584 Added silc_hash_table_replace_ext function as extended
585 replacing function. Separated the simple hash table interface
586 from the extended hash table interface in the file
587 lib/silcutil/silchashtable.h.
589 * Fixed minor bugs and changed it to use some of the new
590 hash table functions in lib/silccore/idcache.c
592 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
594 * Added new function silc_hash_table_find_all to return all keys
595 in the hash table by the specified key. As the hash table is
596 collision resistant it also makes it possible to have several
597 duplicate keys in the hash table. This function may be used to
598 find all of the keys from the hash.
600 Added user_context arguments to the SilcHashFunction,
601 SilcHashCompare and SilcHashDestructor to deliver user specified
604 Added new fuctions silc_hash_table_find[_all]_ext to do
605 extended lookup with specified hash and compare functions and
606 specified user contexts.
608 Added new function silc_hash_table_add_ext to add the key
609 with specified hash function and user context.
611 Added new function silc_hash_table_foreach to traverse all
612 entrys in the hash table. Added SilcHashForeach callback
615 Added new function silc_hash_table_del_by_context to delete
616 the entry only if the context associated with the key matches.
618 Affected files are lib/silcutil/silchashtable.[ch].
620 * Removed silc_hash_[server/client/channel]_id and added just
621 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
622 silc_hash_id_compare to compare two ID's using as the hash table
623 comparison function. Added also silc_hash_data to hash
624 binary data and silc_hash_data_compare to compare it.
626 * Removed silc_idlist_find_client_by_hash as it is not needed
627 anymore. Affected file silcd/idlist.[ch].
629 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
630 to use internally the SilcHashTable. The new ID Cache is a lot
631 faster than the old one. Some of the ID Cache interface was also
632 rewritten and obsolete and stupid functions were removed.
634 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
636 * Added entry_count field to the SilcHashTable to keep the number
637 of the entries in the table. Implemented the function
638 silc_hash_table_rehash. Added new function
639 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
641 Fixed a minor bug in silc_hash_table_free.
643 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
644 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
645 into the lib/silcutil/silcutil.[ch].
647 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
649 * Implemented a collision resistant hash table into the
650 lib/silcutil/silchashtable[ch]. See the header and the source
651 for the SilcHashTable API.
653 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
655 * Merged dotconf version 1.0.2 into lib/dotconf.
657 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
659 * Do not compile anything in lib/silcsim/* if the SIM support
660 is not enabled. The tree should now compile without problems
663 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
665 * Compiled the SILC under cygwin. Compiled and tested briefly
666 without problems. More tests needed. The SIMs didn't compile
669 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
671 * Fixed possible crash in silc_get_username in the
672 lib/silcutil/silcutil.c.
674 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
676 * Fixed a va_arg in silc/client_ops.c.
678 * Oops, RC5 routines were named AES and caused some problems
679 when not using SIM's. Affected file lib/silccrypt/rc5.c.
681 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
683 * Added new SilcIDIP structure into the lib/silccore/id.h and
684 replaced the old `ip' fields from all SILC ID's to that type.
685 This is a step towards IPv6 support.
687 The silc_id_get_len takes now the ID as an extra argument.
688 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
689 both IPv4 and IPv6 based ID's.
691 The affected files are lib/silccore/id.[ch] and other files
692 around the tree using these routines.
694 * Removed the ID length arguments in server from various
695 silc_server_send_notify_* routines -> they are not needed
698 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
700 * Fixed memory leak in silc_encode_pem_file in the file
701 lib/silcutil/silcutil.c.
703 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
705 * Check minor version as well in the SKE. Affected files are
706 silcd/protocol.c and lib/silcclient/protocol.c.
708 * Added --identifier option to the server so that an identifier
709 can be when creating the public key for the server. Affected
710 file is silcd/silcd.c.
712 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
713 lib/silccrypt/silcpkcs.c.
715 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
717 * Register default ciphers and stuff when using -C option with
718 the server. Affected file sildc/silcd.c.
720 * Put back the servers public key filename format, it is better
721 than the new one. For now, the client keys are saved with the
722 new filename format. The affected file silc/client_ops.c.
724 * Implemented the Cipher API for the rest of the ciphers that
725 did not implement it or implemented it the wrong way.
727 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
729 * Register default ciphers and stuff when using the -S option
730 in the client. Affected file silc/silc.c. Same also when
731 creating new key pair with -C option.
733 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
735 * Fixed the silc_verify_public_key client operation function to
736 save the public keys differently. The fingerprint is now
737 used as filename and not the hostname. This way also the
738 client keys are saved uniquely and not with hostnames. The
739 affected file is silc/client_ops.c.
741 * Trimmed the silc_hash_fingerprint function to remove extra
742 whitespaces from the end of the fingerprint. The affected
743 file is lib/silccrypt/silchash.c.
747 * Added silc_cipher_register_default function to register all
748 default ciphers. It can be used when configuration files
749 does not exist and the application does not want any specific
750 ciphers in any specific order.
752 The SilcDList is now used as silc_cipher_list dynamically
753 allocated cipher list. Removed the static list all together
754 and now all ciphers must be allocated to the dynamic list.
755 The silc_cipher_alloc routine was changed to check only the
758 All silc_cipher_* routines that used to return int returns
761 The affected files lib/silccrypt/silccrypt.[ch].
763 * The same thing was done to silc_hash_* as for silc_cipher_*
764 routines. Affected files lib/silccrypt/silchash.[ch].
766 * The same thing was done to silc_pkcs_* as for silc_cipher_*
767 routines. Affected files lib/silccrypt/silcpkcs.[ch].
768 Added also silc_pkcs_[un]register[_default] functions.
769 Removed the data_context from the PKCS API.
771 * Added silc_hmac_register_default function to register default
772 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
773 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
774 to unregister all hmacs at once.
776 * Register the default ciphers, hash functions, PKCSs and HMACs
777 if client's configuration file does not exist. The affected
780 * The client did not load the hash functions from the SIM
781 modules at all. Added support for this. Affected file is
784 * When decoding public key with silc_pkcs_public_key_decode, check
785 the supported algorithm only if PKCS are registered. Affected
786 file lib/silccrypt/silcpkcs.c. The same was done with the
787 silc_pkcs_private_key_decode.
789 * Fixed the SILC List routines to keep the list always in order.
790 It used to change the list's order when traversing the list but
791 not it preserves the order. Affected file lib/trq/silclist.h.
793 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
795 * Added the client library to use the SilcSocketConnection's
796 reference counter (by silc_socket_dup) to prevent the bug that
797 the socket object may be freed underneath async operation.
799 * The name resolv library checking fixes in the configure.in.pre.
802 * Created new version of the protocol drafts for future
803 development. The -03 drafts are the ones that will be changed
804 in the trunk now and the -02 will remain as they are.
806 * Send list of CUMODE notifys to the router when announcing
807 the channel users to the router. Affected file silcd/server.c.
808 If the router receiving channel founder CUMODE for a channel
809 that already has channel founder it will send CUMODE notify
810 to the sender to remove the channel founder rights from the
811 announced client. Affected file silcd/packet_receive.c.
813 * The CUMODE notify may now use Server ID as well as the entity
814 who changes the mode. Updated protocool specs.
816 * Updated INSTALL and README files.
818 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
820 * New web pages in the http://silc.pspt.fi. The pages was
825 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
827 * Implemented the [DenyConnectin] config section in the server.
828 Added silc_server_config_denied_conn to check whether incoming
829 connection is denied. Affected file silcd/serverconfig.[ch].
831 * Do not check the ports when checking the incoming configuration
832 data if the port is 0, meaning any. Affected file is
833 silcd/serverconfig.c.
835 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
837 * Fixed buffer overflow in silc_string_compare in the file
838 lib/silcutil/silcutil.c.
840 * Fixed double free in silc_server_command_leave in the file
843 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
845 * Fixed the version checking in the server. Affected file is
848 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
850 * Fixed the configuration data fetching when accepting new
851 connections in the server. Affected file silcd/server.c.
853 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
855 * Added `sender_entry' argument to the function
856 silc_server_packet_relay_to_channel so that we can check
857 whether some destination actually belongs to the same route
858 the sender belongs (ie, we must not resend the packet to the
859 sender). Affected file silcd/packet_send.[ch].
861 * Added `servername' field to the SilcClientEntry in the server
862 to hold the name of the server where client is from. Affected
863 file is silcd/idlist.h.
865 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
867 * Moved the channel message encrypting in the router betwen
868 router connections from silc_server_channel_message to the
869 silc_server_packet_relay_to_channel since we want to check
870 whether we have anybody channel before encrypting anything.
871 Affected files silcd/packet_[receive/send].c.
873 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
875 * Fixed the [AdminConnection] server config section to support
876 multiple entries. Affected file silcd/serverconfig.c.
878 * Added support into the server to check the validity of the
879 incoming connection before executing any KE or authentication
882 * The connection configuration is now saved to the KE and
883 connection auth protocol contexts and not fetched anymore in
884 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
886 * The local hosts listenning address and port is also resolved
887 now when starting the server. We want to have the socket object
888 to include the real address and port for the listener. Added
889 new function silc_net_check_local_by_sock into the files
890 lib/silcutil/silcnet.[ch].
892 * Fixed a broadcast bug in server -> do not broadcast if we
895 * Fixed a routing bug. Do not route broadcast packets ever.
896 Broadcast packets must be processed always and not routed since
897 they may be destined to some other host than yourself and thus
898 would get routed without no good reason. Affected file is
901 * Added function silc_server_config_is_primary_route to check
902 whether primary router connection has been configured (a router
903 configuration that we are initiating). If there is not, we
904 will assume that there is only two routers in the SILC network
905 and we will use the incoming router connection as our primary
906 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
908 * Changed the order of the broadcasting. Broadcast _after_ the
909 packet has been processed not before. Affected file is
912 * Fixed a [ClientConnection] parsing bug. The port was never
913 parsed correctly thus resulting to port 0. Affected file
914 silcd/serverconfig.c.
916 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
917 argument and did not set the broadcast packet flag. Affected
918 file silcd/packet_send.c. Fixed same bug in the function
919 silc_server_send_notify as well.
921 * If we receive NEW_ID packet for our own ID in the server, ignore
924 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
928 * Removed the nickname from the Private Message Payload.
929 Updated the code and the protocol specs.
931 * Updated protocol specs for submitting to the IETF.
933 * Tweaked the Random Number Generator a bit. Affected file
934 lib/silccrypt/silcrng.c. Exported a new function
935 silc_rng_[global]_add_noise which can be used to add more
938 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
940 * Do not parse packets with different timeout when protocol
941 is active -> may cause problem with rekey. Affected file
944 * When server receives signoff notify it must not create
945 new channel key if the client is on any channels since the
946 sender of the signoff notify will create it.
948 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
950 * Added printing of error messages during SKE protocol from the
951 failure packet sent by server during SKE. Affected file
954 * Removed the client's failure_callback handling with timeout
955 and handle it immediately when received.
957 * The SKE library returned wrong type in SUCCESS and FAILURE
958 packets. They must be 32 bit MSB not 16 bit MSB.
960 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
962 * Ok, rewrote the logic of the re-key and now it seems to work.
963 I tested it on high traffic with frequent re-keys without
964 problems. Added hmac_receive (and renamed hmac to hmac_send)
965 in SilcClientConnection in lib/silcclient/client.h and
966 in SilcIDListData in silcd/idlist.h. Also, removed the
967 SilcPacketParserContext's cipher and hmac fields as they are
968 not needed anymore and actually caused some problems when
969 the ciphers and hmac's changed underneath the packet parser.
971 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
973 * If re-key protocol is active then process the incoming packets
974 synchronously since we must assure that icoming packets encrypted
975 with the old key is processed before the new keys is set to
976 use. This is true other packets than for REKEY packets.
977 Affected file silcd/server.c. The same was done to client library
978 as well, affected file lib/silcclient/client.c.
980 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
982 * Fixed bug in client and server to accept the force send if
983 the packet is send from silc_[server/client]_packet_process
984 function. Otherwise the packets are never delivered, oops.
986 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
988 * Disable force sending of packets when REKEY protocol is active.
989 We must assure that no packet is sent directly when rekey is
990 performed. All packets must be sent through packet queue.
991 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
992 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
993 function is silc_[server/client]_packet_send_real to check
996 * Replaced the SIM paths from example config files to
997 /usr/local/modules. Also, make install creates now
998 /usr/local/silc/logs directory to hold all the SILC server
1001 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1003 * Made the configure.in.pre work on Solaris. Patch by salo.
1005 * Made all ciphers compatible with non-x86 machines. Defined
1006 CBC mode macros into lib/silccrypt/ciphers_def.h.
1008 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Fixed the make install.
1012 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1014 * When MAC computation fails the silc_packet_decrypt returned 0
1015 even though it was supposed to return -1. Fixed this. The
1016 affected file is lib/silccore/silcpacket.c.
1018 * Do not replace the config files in /etc/silc (in make install)
1019 if they already exist. Affected file ./Makefile.am.
1021 * Do not send re-key packets immediately but through packet queue.
1022 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1024 * Changed silc_net_check_host_by_sock to return FALSE if the
1025 IP/DNS could not be resolved. Though, it returns the IP address
1026 now even if it could not resolve it (but returns also FALSE).
1027 Affected file lib/silcutil/silcnet.[ch].
1029 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * Added silc_pkcs_decode_identifier to decode the public key's
1032 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1033 Added also silc_pkcs_free_identifier. Added also new context
1034 SilcPublicKeyIdentifier.
1036 * Added -S option to the silc client. It is used to dump the
1037 contents of the specified public key file.
1039 * Changed the PKCS api to return the public key length when
1040 setting the public key.
1042 * Fixed a fatal bug in the public and private key file loading.
1043 Affected file lib/silccrypt/silcpkcs.c.
1045 * Execute the packet parsing for client with zero (0) timeout
1046 if the protocol is active. Affected file silcd/server.c.
1048 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1050 * Made the key generation options to the silcd program. Added
1051 -C option, equivalent to client's option.
1053 * Added new [ServerKeys] config section to the server. It
1054 configures the server's public and private key.
1056 * Defined generic Public Key Payload into the protocol
1057 specification to send specific type of public keys and
1060 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1061 public key or certificate.
1063 * Implemented the GETKEY command to the server and to the
1064 client library and on user interface.
1066 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1068 * Made preliminary `make install' work.
1070 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1072 * Added SilcServerRekey context into silcd/idlist.h.
1074 * Added the PFS support as defined in the specification to the
1075 SKE protocol. Affected files lib/silcske/*.c.
1077 * Added `ske_group' field to the SilcServerRekey context to hold
1078 the number of the SKE group that is used with PFS in re-key.
1079 Affected file silcd/idlist.h.
1081 * Added PFS re-key support to the server. Affected file is
1084 * Added silc_protocol_cancel to cancel execution of the next
1085 state of the protocol. Affected file is
1086 lib/silccore/silcprotocol.[ch].
1088 * Added the re-key support with and without PFS to the client
1089 library. Re-key is performed once in an hour, by default.
1091 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1092 Added silc_client_rekey_callback and silc_client_rekey_final.
1093 Affected files are lib/silcclient/protocol.[ch] and
1094 lib/silcclient/client.[ch].
1096 * Removed the `hmac_key' and `hmac_key_len' fields from the
1097 SilcClientConnection structure; not needed. Affected file is
1098 lib/silcclient/client.h.
1102 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Do not ask whether user wants to use the negotiated private key
1105 for private messages, just use it. Affected file is
1106 silc/local_command.c.
1108 * Added `send_enc_key' and `enc_key_len' fields to the
1109 SilcIDListData structure since they are needed in the re-key
1110 phase. Affected file is silcd/idlist.[ch].
1112 * Implemented the simple re-key protocol into the server.
1113 Affected files silcd/server.c and silcd/protocol.[ch]. The
1114 re-key will be performed once in an hour, by default.
1116 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1117 Added silc_server_rekey, silc_server_rekey_callback and
1118 silc_server_rekey_final.
1120 * Removed Tunneled flag from the protocol. Updated the code
1121 and the specifications.
1123 * Adde `pfs' field to the SilcIDListData to indicate whether
1124 the PFS is to be performed in the re-key. Affected file is
1127 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1129 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1130 int64 of at least the xintXX size. If void * is less that 4
1131 bytes uint32 * will be used. Defined bool as boolean.
1133 * Changed _ALL_ unsigned long and unsigned int to uint32,
1134 unsgined short to uint16 in the source tree.
1136 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1137 not handle clients that has entry->data.registered == FALSE.
1138 They are not in the network anymore. Affected file is
1141 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Implemented the sending of the SERVER_SIGNOFF notify in the
1144 server. Affected file is silcd/server.c.
1146 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1147 Added also silc_notify_payload_encode_args into the
1148 lib/silccore/silcnotify.[ch].
1150 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1151 Affected file silcd/packet_receive.c.
1153 * Implemented the SERVER_SIGNOFF notify handling in the client
1154 library. Affected file lib/silcclient/client_notify.c. Also,
1155 implemnted the printing of the SERVER_SIGNOFF info to the
1156 application. Affected file silc/client_ops.c.
1158 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1159 if the deleting was successful. Affected file silcd/idlist.[ch].
1161 * Added support for public key authentication in the connection
1162 authentication protocol in the client library. Affected file
1163 lib/silcclient/protocol.c.
1165 * Changed the server's silc_idlist_get_clients_by_* interface
1166 to support already allocated array so that new entries may be
1167 added to pre-allocated array. Affected file silcd/idlist.[ch].
1168 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1169 and command replies.
1171 * All command reply functions in the server now calls the
1172 pending command callback even if error occured. This way the
1173 error will be delivered to the client as well. Affected files
1174 silcd/command.c and silcd/command_reply.c.
1176 * Fixed INFO command to return local server's info if no server
1177 was provided. Affected file lib/silcclient/command.c.
1179 * Removed RESTART command for good. Updated the code and the
1182 * Rewrote parts of the task system. It is a bit simpler now.
1183 Removed unsued task priorities. The affected files are
1184 lib/silcutil/silctask.[ch].
1186 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1188 * Moved the USERS printing from the library to the application.
1189 Affected files lib/silcclient/command.c and silc/client_ops.c.
1191 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1195 * Added channel key re-key support. The re-key is perfomed
1196 only by the router and is done once in an hour. Added `rekey'
1197 field to the SilcChannelEntry in the server. Affected files
1198 silcd/server.c and silcd/idlist.h.
1200 * Added silc_task_unregister_by_context into the file
1201 lib/silcutil/silctask.[ch].
1203 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1205 * Added SILC_UMODE_GONE mode to indicate when the client is not
1206 present in the SILC network. Added also support to the local
1207 command AWAY that will set this mode. Added support of showing
1208 "xxx is gone" in WHOIS command. The USERS command shows the
1209 gone status as well.
1211 * Fixed setting server and router operator privileges in the
1212 server's UMODE command. Affected file silcd/command.c.
1214 * Merged the SKE KE1 and KE2 payloads into one payload. The
1215 new KE payload is equivalent to the old KE2 payload.
1217 Cleaned up the SKE Start Payload parsing. It now uses the
1218 simple buffer unformatting to do the parsing. A lot faster
1221 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1222 to the SKE that is used to indicate whether both of the SKE
1223 parties should perform authentication. By default only the
1224 responder performs authentication. By setting this flag also
1225 the initiator must do authentication. By default it is unset
1226 since in normal SKE case, client to server connection, only
1227 the responder should do authentication. When doing SKE between
1228 two clients both should perform authentication. Updated the
1229 code and the protocol specs.
1231 * A little fix to IDENTIFY command in the server. Search the
1232 client first by hash not nickname. Affected file is
1235 * Fixed the silc_client_close_connection to support closing
1236 the client to client connections wihtout deleting too much
1237 data. Affected file lib/silcclient/client.c.
1239 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1240 are received if protocol used to be active but is not anymore
1241 the application would crash due to NULL pointer dereference.
1242 Affected files silcd/server.c and lib/silcclient/client.c.
1244 * Added `hash' field to the SilcClientConnection to include
1245 the hash function negotiated in the SKE protocol.
1247 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1248 to set the channel founder authentication data. A client can
1249 claim the founder rights later by providing the authentication
1250 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1251 This way the channel founder can regain the channel founder
1252 privileges even it is left the channel. This works only on
1253 local server and the client must be connected to the same
1254 server to be able to regain the founder rights. Updated the
1255 protocol specs accordingly.
1257 Added support to the CMODE command in the client to set the
1258 founder auth data. Read the README to see how to set it.
1260 Added support to the CUMODE command to claim the founder
1261 rights. Read the README to see how to do it.
1263 Added support for the founder authentication to the Channel
1264 Entry in the server. Affected file silcd/idlist.h.
1266 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1267 server's CMODE command. Affected file silcd/command.c.
1269 * Added the following new functions into lib/silccore/silcauth.[ch]:
1270 silc_auth_get_method and silc_auth_get_data.
1272 * The server now saves the remote hosts public key to the
1273 SilcIDListData pointer. Affected file silcd/protocol.c.
1275 * The normal server now does not remove the channel entry from
1276 the cache if the founder authentication data is set. It used
1277 to remove it if the founder was the last one on the channel on
1278 the server and left the channel. The auth data is saved and
1279 if the channel is re-joined later the old entry is used with
1280 the old auth data. Affected files silcd/command_reply.c and
1283 * Removed the `pkcs' field from the SilcIDListData structure
1284 in the server; it is not used. Affected file silcd/idlist.h.
1286 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1288 * Fixed packet processing on slow links. Partial packets were
1289 never re-processed because the incoming data buffer was cleared
1290 by the application. Application must not directly clear the
1291 sock->inbuf, the packet processing routines handle it. Fixed
1292 this in client library and in server.
1294 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1296 * Fixed the WHOIS and IDENTIFY send reply function to really
1297 check whether to send list or just one entry. Affected file
1300 * Cleaned up the LEAVE command's channel key distribution. The
1301 affected file silcd/command.c.
1303 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1304 can enforce the channel mode as well. In that case the ID
1305 includes the ID of the server. The code now enforces the
1306 mode change if the router have different mode than the server.
1308 * The notify client operation with CMODE_CHANGE notify can now
1309 return NULL client_entry pointer if the CMODE was not changed
1310 by client. Application must check for this.
1312 * Added <Server ID> argument to INFO command to support server
1313 info fetching by Server ID.
1315 * Added silc_server_announce_get_channel_users to get assembled
1316 packets of channel users of the specified channel. Affected
1317 file silcd/server.[ch].
1319 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1320 was freed underneath the ID Cache.
1322 * Re-announce clients when the server received CHANNEL_CHANGE
1323 notify from the router. Affected file silcd/packet_send.c.
1325 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1327 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1328 crashed since it did not handle the fact that there is no cipher
1329 called "3" and didn't check the error condition. Now fixed.
1331 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1332 flag. It can be used to send message requests.
1334 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1336 * Implemented the RESTART command in the client.
1338 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1339 notice type messages. Added notice printing to the user
1342 * The channel keys are not re-generated if the channel's mode
1343 is PRIVKEY, ie private key on the channel exists. Affected
1344 files silcd/server.c and silcd/command.c.
1346 * Fixed a little bug in channel message delivery when channel
1347 private keys are set in the server. Affected file is
1348 silcd/packet_send.c.
1350 * Changed the setting on channel->on_channel = TRUE from the
1351 silc_client_save_channel_key to the JOIN command reply. The
1352 key payload is not received if the private channel key is set.
1353 Affected file lib/silcclient/command_reply.c and the
1354 lib/silcclient/client_channel.c.
1356 * When the CMODE_CHANGE notify is sent and the channel private
1357 key mode is removed the channel key must be re-generated in
1358 other cells as well. Added this support for the router in the
1359 silcd/packet_receive.c.
1361 * Added new local command NOTICE to send notice message on
1362 channel. Affected file silc/local_command.[ch].
1364 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1366 * Added new local command ME to the client. It is used to send
1367 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1368 some action. Affected file silc/local_command.[ch].
1370 * Changed channel_message and private_message client operations
1371 to deliver the message flags to the application. Added also
1372 the `flags' arguments to the silc_client_send_channel_message
1373 and silc_client_send_private_message functions. Affected file
1376 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1378 * Redefined the Private Message Payload to support private message
1379 keys and to support the new private message flags. Updated
1380 the protocol specs. Flags makes it possible to have for example
1381 CTCP style messages.
1383 * Added new type SilcPrivateMessagePayload and defined an API
1384 for it in the lib/silcclient/silcprivate.[ch].
1386 * Tested private message private keys successfully. Tested the
1387 private message key set, unset and list commands with the new
1390 * Redefined the Channel Message Payload to include the channel
1391 message flags (equal with private message flags) to support
1392 for example CTCP style messages.
1394 * Defined some of the message (for channel and private message)
1395 flags. Updated the protocol specs and added the flags to the
1396 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1398 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1400 * Added SilcKeyAgreementStatus type to the key agreement routines
1401 to indicate the current status and error if one occured.
1402 The status types are defined in the lib/silcclient/silcapi.h.
1404 * Added new local command KEY that is used to set and unset private
1405 keys for channels, set and unset private keys for private messages
1406 with remote clients and to send key agreement requests and
1407 negotiate the key agreement protocol with remote client. The
1408 key agreement is supported only to negotiate private message keys,
1409 it currently cannot be used to negotiate private keys for channels,
1410 as it is not convenient for that purpose.
1412 * Fixed a minor pending callback setting bug in the function
1413 silc_client_get_client_by_id_resolve, now the function works.
1414 Affected file lib/silcclient/idlist.c.
1416 * Added function silc_net_get_local_port to get local bound
1417 port by socket. Added to lib/silcutil/silcnet.[ch].
1419 * Added `sockets' and `sockets_count' fields to the SilcClient
1420 object. They hold the sockets of the listenning sockets in
1421 the client. Listenning sockets may be for example the key
1422 agreement server. Affected file lib/silcclient/client.[ch].
1423 Added functions the silc_client_add_socket and the
1424 silc_client_del_socket. They are exported to the application
1427 * Added ~./silc/clientkeys to support other client's public keys.
1429 * Renamed verify_server_key client operation to verify_public_key
1430 and added one argument to indicate the type of the connection
1431 (server, client etc.).
1433 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1435 * Added silc_server_connection_auth_request to handle the
1436 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1437 silcd/packet_receive.[ch].
1439 * Added silc_server_send_connection_auth_request into the
1440 silcd/packet_send.c to send the connection auth request packet.
1442 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1445 * Fixed the public key authentication in responder side in the
1446 server. The `auth_data' pointer includes the SilcPublicKey
1447 not the path to the public key. Affected file silcd/protocol.c.
1449 * Implemented the public key authentication in the initiator side
1450 in the server. Affected file silcd/protocol.c.
1452 * Removed the [RedirectClient] config section from the server
1453 configuration. Is not needed and I don't want to implement it.
1455 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1457 * Cleaned up the CMODE command in the server. It now works
1458 correctly and supports all the modes defined in the protocol.
1459 Affected file is silcd/command.c.
1461 * Added `hmac_name' field to the SilcChannelEntry in the server
1462 to hold the default HMAC of the channel. It can be set when
1463 creating the channel (with JOIN command). Affected files
1466 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1467 type to indicate the change of the current cipher and hmac
1468 on the channel. Client can safely ignore the <cipher> argument
1469 (if it chooses to do so) since the CHANNEL_KEY packet will
1470 force the channel key change anyway. The <hmac> argument is
1471 important since the client is responsible of setting the new
1472 HMAC and the hmac key into use.
1474 * Fixed the CMODE command in the client library as well.
1476 * Tested CMODE command in router environment successfully.
1478 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1480 * Show the version of the remote client (or server) when connecting
1481 to the server. It is logged to the log file. Affected file
1482 is silcd/protocol.c.
1484 * Fixed the KILLED notify handling in the client library. The
1485 client must be removed from all channels when receiving the
1488 Also, do not remove the client entry when giving the KILL
1489 command but when the KILLED notify is received.
1491 * Removed silc_idlist_find_client_by_nickname from the server.
1492 Not needed anymore. Affected files silcd/idlist.[ch].
1494 * Implemented the CHANNEL_CHANGE notify type handling to the
1495 server. Affected file silcd/server.c.
1499 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * Added silc_server_send_notify_invite to send the INVITE
1502 notify between routers.
1504 * Implemented the INVITE command correctly to the server.
1506 * Implemented the INVITE notify type handling in the server.
1508 * Implemented the INVITE command to the client library and on the
1511 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1513 * Added function silc_server_get_client_resolve to find the
1514 client entry by ID from all ID lists and then resolve it
1515 (using WHOIS) if it cannot be found. Affected file is
1518 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1520 * Implemented the BAN command to the client library.
1522 * The JOIN command in the server now checks the invite list
1525 * Changed the silc_command_reply_payload_encode_va and the
1526 silc_command_payload_encode_va to support that if argument is
1527 NULL it ignores and checks the next argument. Affected file
1528 lib/silccore/silccommand.c.
1530 * Added silc_server_send_notify_ban to send the BAN notify
1531 type between routers.
1533 * Chaned the silc_notify_payload_encode to support that if
1534 argument is NULL it ignores and checks the next argument.
1535 Affected file lib/silccore/silcnotify.c.
1537 * Tested ban lists in router environment successfully.
1539 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1541 * Implemented BAN command to the server, in silcd/command.[ch].
1543 * Removed the BAN and INVITE_LIST modes from the CMODE command
1546 * Added function silc_string_match to regex match two strings.
1547 Affected files lib/silcutil/silcutil.[ch].
1549 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1551 * Redefined parts of the SilcChannelEntry in the server to support
1552 the new ban and invite lists.
1554 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1556 * Redefined the INVITE command. The same command can be used to
1557 invite individuals to the channel but also to manage the invite
1558 list of the channel (to add to and remove from the invite list).
1559 Updated the protocol specs.
1561 * Added new command SILC_COMMAND_BAN that can be used to manage
1562 the ban list of the channel. Updated the protocol specs.
1564 * Removed the channel modes: the SILC_CMODE_BAN and the
1565 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1566 in the CMODE command. The equivalent features are now available
1567 using INVITE and BAN commands. Updated the protocol specs.
1569 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1570 in the network about change in the current ban list. The notify
1571 type is not used by the client.
1573 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1574 support the invite lists.
1576 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Added new function silc_string_regexify that converts string
1579 including wildcard characters into regex string that can
1580 be used by the GNU regex library. Added into the file
1581 lib/silcutil/silcutil.[ch].
1583 Added silc_string_regex_combine to combine to regex strings
1584 into one so that they can be used as one regex string by
1585 the GNU regex library. Added into the file
1586 lib/silcutil/silcutil.[ch].
1588 Added silc_string_regex_match to match two strings. It returns
1589 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1591 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Imported GNU regex to the soruce tree into lib/contrib.
1594 Fixed some compiler warning from the regex.c.
1596 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1598 * Fixed MOTD command in the server to work in router environment.
1600 * Fixed the MOTD command in the client library to support
1601 the server argument in the command.
1603 * Added `nickname_len' argument to the silc_idlist_add_client
1604 in the server, as the `nickname' argument may be binary data
1607 * Added silc_idlist_get_channels to return all channels from
1610 * Implemented LIST command to the server. Affected file is
1613 * Implemented the LIST command to the client library and on the
1616 * Added [<user count>] argument to the LIST command reply.
1617 With private channels the user count is not shown.
1619 * Updated TODO and README.
1621 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1623 * The client entry's data.registered must be TRUE even with
1624 global client entry on global client list. The data.registered
1625 is used to check whether the client is anymore in the network,
1626 for example with WHOWAS command so it must be valid.
1628 * Fixed the WHOWAS command in the server. It now actually works
1629 in router environment. Added function into silcd/command_reply.c
1630 silc_server_command_reply_whowas_save.
1632 * Added silc_idlist_purge function to the silcd/idlist.c
1633 to periodically purge the ID Cache.
1635 * Fixed INFO command in the server. It works now in router
1636 environment. Added <server name> argument to the INFO command
1637 reply. Updated the protocol specs.
1639 * Fixed minor bug in silc_idcache_purge to not purge if the
1640 expire value is zero.
1642 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1643 they were buggy because of the WHOWAS information.
1645 * Fixed local command MSG to handle the async resolving of
1646 the remote client properly. It used to fail the first MSG.
1647 Affected file silc/local_command.c.
1649 * Added `data_len' field to SilcIDCache context.
1651 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1653 * Update TODO. Todo in commands in the server.
1655 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1657 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1658 used by routers as broadcast packet to inform other routers
1659 about the changed user mode.
1661 Implemented the notify handling in the server. Affected file is
1662 silcd/packet_receive.c. Added the function
1663 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1665 * Added new generic Channel Payload and deprecated the New Channel
1666 Payload. The New Channel Payload is now the generic Channel
1669 * Added new argument `mode' to the silc_server_send_new_channel
1670 as it is required in the Channel Payload now.
1672 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1673 and created a new and real SilChannelPayload to represent the
1674 new generic Channel Payload. Implemented the encode/decode
1675 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1677 * Added silc_server_get_client_channel_list to return the list
1678 of channels the client has joined for WHOIS command reply.
1679 Affected file silcd/server.[ch].
1681 * Implemented the channel list sending in the WHOIS command reply
1682 in server and in the client.
1684 Implemented the channel list displaying on the user interface
1685 as well. Affected file silc/client_ops.c.
1687 * Added silc_channel_payload_parse_list to parse list of Channel
1688 Payloads. It returns SilcDList list of SilcChannelPayloads.
1689 Client for example can use this function to parse the list of
1690 channels it receives in the WHOIS command reply. The caller
1691 must free the list by calling silc_channel_payload_list_free.
1692 Affected files lib/silccore/silcchannel.[ch].
1694 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1696 * Added one new argument <user mode> to the WHOIS command reply
1697 to return the mode of the user in SILC. Updated the protocol
1700 Implemented it to the server and client.
1702 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1704 * Fixed the mode printing on the user interface on joining.
1705 Affected file silc/client_ops.c.
1707 * Implemented the UMODE command and user modes in general to the
1708 client library and to the user interface.
1710 * Implemented the UMODE command to the server.
1712 * The server now sends UNKNOWN_COMMAND error status if client sends
1713 unknown command. Affected file silcd/command.c.
1715 * All server commands now handle the command identifier the right
1716 way when sending the command reply to the client. The client can
1717 use to identify the command replies with the identifier.
1719 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1721 * Added silc_server_get_client_route to resolve the route to
1722 the client indicated by the client ID. Affected file is
1725 * Added silc_server_relay_packet as general function to relay
1726 packet to arbitrary destination. This deprecates functions
1727 like _send_private_message_key, _relay_notify etc. Affected
1728 file is silcd/packet_send.[ch].
1730 Removed silc_server_send_key_agreement,
1731 silc_server_send_private_message_key and
1732 silc_server_packet_relay_notify functions from the file
1733 silcd/packet_send.[ch].
1737 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1738 server. Affected file silcd/packet_receive.[ch].
1740 * Implemented the KILL command to the client. Implemented the
1741 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1742 Affected files lib/silcclient/command[_reply].c and
1743 lib/silcclient/client_notify.c. Implemented the KILL notify
1744 printing in the user inteface.
1746 * Fixed a lot silc_parse_nick memory leaks from the client
1747 library in the file lib/silcclient/command.c.
1749 * Changed the silc_server_send_notify_on_channels's `sender'
1750 argument from SilcSocketConnection to SilcClientEntry to
1751 check the sender as entry and not as connection object and not
1752 to send to the client provided as argument. The affected file
1753 is silcd/packet_send.[ch].
1755 * The notify packets that are destined directly to the client used
1756 to not to be processed by the server. Now changed that and the
1757 server processes all notify packets. After relaying the packet
1758 to the client the notify packet is processed in the server.
1760 * The silc_server_free_client_data now checks whether there is
1761 pending outgoing traffic for the client and purges the data to
1762 the network before removing the client entry.
1764 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1766 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1767 an client is killed from the SILC Network. Updated the protocol
1770 Added new function silc_server_send_notify_killed to the
1771 silcd/packet_send.[ch].
1773 * Added function silc_server_packet_relay_notify to relay notify
1774 packets that are destined directly to a client. In this case
1775 the server does not process the notify packets but merely relays
1776 it to the client. Affected file silcd/packet_send.[ch].
1778 Added also silc_server_packet_process_relay_notify to check
1779 whereto relay the notify. Affected file is
1780 silcd/packet_receive.[ch].
1782 * Implemented the KILL command to the server.
1786 * Added the backup schema desgined last fall to the protocol
1787 specs for everyone to see. The specification is in the
1788 *-spec-xx.txt draft and the packet type definitions for the
1789 backup routers is in *-pp-xx.txt draft. Thusly, added also
1790 new packet type SILC_PACKET_CELL_ROUTERS.
1792 * A big security problem in the implementation discovered. The
1793 signoff of an client did not cause new channel key generation
1794 which it of course should've done. The channel keys must be
1795 always re-generated when client leaves (or signoffs) the channel.
1796 The silc_server_remove_from_channels funtion now handles
1797 the channel key re-generation.
1799 * Added `sender' argument to the silc_server_send_notify_on_channels
1800 to not to send the client provided as argument. Affected file
1801 silcd/packet_send.[ch].
1803 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Implemented OPER and SILCOPER commands into the server and
1808 * Added silc_auth_verify and silc_auth_verify_data to verify
1809 the authentication directly from the authentication payload.
1810 It supports verifying both passphrase and public key based
1811 authentication. Affected file lib/silccore/silcauth.[ch].
1813 * Added `hash' field to the SilcIDListData structure. It is the
1814 hash negotiated in the SKE protocol. Affected file is
1817 * Slight redesigning of the SilcAuthPayload handling routines.
1818 Do not send SilcPKCS but SilcPublicKey as argument.
1820 * Implemented the public key authentication support to the
1821 serverconfig. The public key is loaded from the provided path
1822 and saved as authentication data to void * pointer. Thus,
1823 changed the unsigned char *auth_data to void *auth_data;
1825 * Fixed SHUTDOWN command to send the reply before the server
1826 is shutdown. :) Affected file silcd/command.c.
1828 * Fixed fatal bug in CONNECT command. The hostname was invalid
1829 memory and server crashed. Affected file silcd/command.c.
1831 * Fixed fatal bug in CLOSE command. The server_entry became
1832 invalid but was referenced later in the command. Affected file
1835 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Fixed fatal bug in failure packet handling. Server ignored
1838 the failure and thus crashed when it came.
1842 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1844 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1845 that the command may be executed only once in (about) 2 seconds.
1846 The old SILC_CF_LAG flag is same but allows command bursts up
1847 to five before limiting.
1849 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1850 server code. Various commands now includes the CF_LAG_STRICT
1851 flag to disallow any kind of miss-use of the command.
1853 * Fixed the silc_buffer_unformat to not to allocate any data
1854 if the length of the data is zero. It used to allocate the
1855 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1857 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * Changed the format of AdminConnection configuration section
1860 in the server. Added username of the admin to the format.
1861 Affected files silcd/serverconfig.[ch].
1863 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1864 to return admin configuration data by host, username and/or
1867 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1869 * Implemented WHOWAS command to the server. Added the functions:
1871 silc_server_command_whowas_parse,
1872 silc_server_command_whowas_send_reply,
1873 silc_server_command_whowas_from_client and
1874 silc_server_command_whowas_from_server
1876 * Added <Client ID> argument to the WHOWAS command reply. Updated
1877 the protocol specs accordingly.
1879 * Implemented WHOWAS command and command_reply to the client
1882 Implemented the WHOWAS printing on the user interface.
1884 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1886 * Added new argument to the WHOWAS command reply, the real name.
1887 It is an optional argument. Updated the protocol specs.
1889 * Added SilcIDCacheDestructor callback that is registered when
1890 the SilcIDCache is allocated. The callback is called when
1891 an cache entry in the ID Cache expires, or is purged from the
1892 cache. Added into lib/silccore/idcache.[ch].
1894 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1895 to destruct the client entries when the cache entry expires.
1896 Other ID Cache's in server and in the client library ignores
1899 * If the ID Cache entry's `expire' field is zero then the entry
1900 never expires. Added boolean `expire' argument to the
1901 silc_idcache_add function in the lib/silccore/idcache.[ch].
1902 If it is TRUE the default expiry value is used.
1904 * Added silc_server_free_client_data_timeout that is registered
1905 when client disconnects. By default for 5 minutes we preserve
1906 the client entry for history - for WHOWAS command.
1908 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1910 * Added support to the server to enforce that commands are not
1911 executed more than once in 2 seconds. If server receives
1912 commands from client more frequently, timeout is registered
1913 to process the commands. Affected file silcd/command.c.
1914 Added new function silc_server_command_process_timeout.
1916 * Changed NICK_NOTIFY handling in client library to check that
1917 if the client's nickname was changed, so there is no need to
1918 resolve anything from the server.
1920 * Removed error printing from the WHOIS and IDENTIFY commands.
1921 If error occurs then it is ignored silently in the client library.
1922 The application, however, may map the received error to
1923 human readable error string. The application currently maps
1924 the NO_SUCH_NICKNAME error to string.
1926 * Made the command status message public to the application. Moved
1927 them from lib/silcclient/command_reply.c to
1928 lib/silcclient/command_reply.h. The application can map the
1929 received command status to the string with the
1930 silc_client_command_status_message function.
1932 * Added check to the server to check that client's ID is same
1933 as the Source ID in the packet the client sent. They must
1936 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1938 * Added dist-bzip hook to the Makefile.am to make bzip2
1939 compressed distributions.
1941 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1943 * Server now enforces the maximum length for the nickname and
1944 the channel as protocol specification dictates. 128 bytes for
1945 nickname and 256 bytes for channel name.
1947 * Moved the WHOIS printing to the application. The client libary
1948 does not print out the WHOIS information anymore, the application
1949 must do it. Renamed silc_client_command_reply_whois_print to
1950 the silc_client_command_reply_whois_save.
1952 The client's idle time is also sent to the application now, and
1953 the idle is shown on screen.
1955 * Added silc_client_command_reply_identify_save to save the
1956 received IDENTIFY entries.
1958 * Do not check for channel private keys in message sending and
1959 reception if the channel does not have the PRIVKEY mode set.
1960 Affected file lib/silclient/client_channel.c.
1962 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1964 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1965 just surfaced after chaning the JOIN procedure.
1967 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1969 * Added silc_client_get_clients_by_list to get client entries
1970 from Client ID list, that is returned for example by JOIN
1971 and USERS command replies. The application should use this
1972 function for example when JOIN command reply is received to
1973 resolve the clients already on the channel (library does not
1974 do that anymore as USERS command reply is not used in the JOIN
1975 procedure anymore). Affected files lib/silcclient/silcapi.h and
1976 lib/silcclient/idlist.c.
1978 * JOIN command reply and USERS command reply returns now SilcBuffer
1979 pointers instead of unsigned char pointers when returning
1980 the client list and mode list.
1982 * Added <Client ID> argument to the JOIN command reply, mainly
1983 for the server to identify for which client the command was
1984 originally sent. Updated protocol specs accordingly.
1986 * Added SilcDlist private_key pointer to the SilcChannelEntry
1987 in the client to support the channel private keys. Affected
1988 file is lib/silcclient/idlist.h.
1990 * Added SilcChannelPrivateKey argument to the function
1991 silc_client_send_channel_message so that application can choose
1992 to use specific private ke if it wants to. If it is not provided,
1993 the normal channel key is used, unless private keys are set.
1994 In this case the first (key that was added first) is used
1995 as the encryption key.
1997 * Implemented the support for channel private key handling.
1998 Implemented the following functions:
2000 silc_client_add_channel_private_key,
2001 silc_client_del_channel_private_keys,
2002 silc_client_del_channel_private_key,
2003 silc_client_list_channel_private_keys and
2004 silc_client_free_channel_private_keys
2006 Affected file lib/silcclient/client_channel.c.
2008 * Added the support for the private keys in the channel message
2009 sending and encryption and in the message reception and
2010 decryption. Affected funtions are
2011 silc_client_send_channel_message and silc_client_channel_message.
2013 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2015 * Added SKE's key verify callback to the client library's
2016 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2018 * Removed the statement that server (or router) must send USERS
2019 command reply when joining to the channel so that the client
2020 knows who are on the channel. Instead, the client list and
2021 client's mode list is now sent in the JOIN command reply to the
2022 client who joined channel. This is better solution.
2024 * Added function silc_server_get_users_on_channel and function
2025 silc_server_save_users_on_channel to the silcd/server.[ch].
2027 * Removed function silc_server_command_send_users from the
2030 * Do not show topic on the client library anymore. The topic is
2031 sent in the command reply notify to the application and the
2032 application must show the topic now.
2034 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2036 * Added client searching by nickname hash into the IDENTIFY and
2037 WHOIS commands in the server as they were clearly missing from
2038 them. Affected file is silcd/command.c.
2040 * Fixed a bug in private message receiving in the client library.
2041 The remote ID was freed and it wasn't supposed, now it is
2044 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2046 * Minor fix to the channel payload; allocate the data area, as it
2047 needs to be of specific length.
2049 * If the key agreement port is zero then the operating
2050 system will define the bound port. Affected files are
2051 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2053 * Added new function silc_channel_payload_decrypt into the file
2054 lib/silccore/silcchannel.[ch].
2056 * Moved the channel message etc, check from silc_packet_decrypt
2057 to applications. The library calls now a generic
2058 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2059 when the packet is either normal or special. This was done to
2060 allow more wide range of checking that was not allowed when
2061 the code was in library. Now applications can do virtually any
2062 checks to the packet and return to the library the decision how
2063 the packet should be processed. Affected files are
2064 lib/silccore/silcpacket.[ch].
2066 Added silc_server_packet_decrypt_check to the server and
2067 silc_client_packet_decrypt_check to the client library.
2069 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2070 to send with specified source and destination information.
2072 * Channel message delivery between routers was broken after the
2073 channel key distribution was fixed earlier. The channel key
2074 was used be to distributed to other routers as well which is not
2075 allowed by the protocol. Now this is fixed and channel keys
2076 really are cell specific and the channel message delivery between
2077 routers comply with the protocol specification.
2079 * Fixed various commands in server to check also the global list
2080 for the channel entry and not just the local list. The affected
2081 file silcd/command.c.
2083 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * Added assert()s to buffer formatting and unformatting routines
2086 to assert (if --enable-debug) when error occurs. Affected
2087 file: lib/silcutil/silcbuffmt.c.
2089 * Changed to auto-reconnect to check whether the remote host is
2090 router and register the re-connect timeout if it is. It used
2091 to check that whether we are normal server, but router must do
2092 auto-reconnect with another router as well. Affected file
2095 * Removed the [<key len>] option from CMODE command as the cipher
2096 name decides the key length, nowadays. See the defined ciphers
2097 from the protocol specification.
2099 * Added [<hmac>] option to the CMODE command to define the HMAC
2100 for the channel. Added SILC_CMODE_HMAC channel mode.
2102 * Added [<hmac>] option for the JOIN command so that user can
2103 select which HMAC is used to compute the MACs of the channel
2106 * Added Hmac field to the Channel Message Payload. The integrity
2107 of plaintext channel messages are now protected by computing
2108 MAC of the message and attaching the MAC to the payload. The
2109 MAC is encrypted. Now, it is clear that this causes some
2110 overhead to the size of the packet but rationale for this is that
2111 now the receiver can verify whether the channel message decrypted
2112 correctly and also when private keys are set for the channel the
2113 receiver can decrypt the packet with several keys and check from
2114 the MAC which key decrypted the message correctly.
2116 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2117 lib/silccrypt/silccipher.[ch].
2119 * Added silc_hash_len to return the digest length into the
2120 lib/silcrypt/silchash.[ch].
2122 * Rewrote parts of Silc Channel Payload interface in the
2123 lib/silccore/silcchannel.[ch]. The encode function now also
2124 encrypts the packet and parse function decrypts it.
2126 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2128 * Fixed a minor formatting bug in the SKE's key material processing.
2129 It actually might have processed the keys wrong way resulting
2132 * Redefined the mandatory HMAC algorithms and added new algorithms.
2133 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2134 and hmac-md5 truncated to 96 bits. The mandatory is now
2135 hmac-sha1-96. Rest are optional (including the one that used
2136 to be mandatory). Rationale for this is that the truncated HMAC
2137 length is sufficient from security point of view and can actually
2138 make the attack against the HMAC harder. Also, the truncated
2139 HMAC causes less overhead to the packets. See the RFC2104 for
2142 * Added new [hmac] configuration section. The SKE used to use
2143 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2144 is of course wrong. The official names that must be proposed in
2145 the SKE are the ones defined in the protocol specification
2146 (hmac-sha1-96 for example). The user can configure any hmac
2147 using any hash function configured in the [hash] section. At
2148 least, the mandatory must be configured.
2150 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2152 * Added HMAC list to the SKE proposal list. It has now both
2153 hash algorithm list and HMAC list. This makes the protocol
2154 incompatible with previous versions. The SKE now seems to work
2155 the way it is supposed to work, for the first time actually.
2157 * Defined plain Hash algorithms to the protocol specification.
2160 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2162 * Implemented support for key agreement packets into the server.
2163 Added functions silc_server_key_agreement and
2164 silc_server_send_key_agreement. Other than these functions,
2165 server has nothing to do with this packet.
2167 * Added support for private message key packets into the server.
2168 Added functions silc_server_private_message_key and
2169 silc_server_send_private_message_key.
2173 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2174 called in the protocol's final callback instead in the END
2175 protocol state. This makes a little more sense and in the same
2176 time in client we can use the same protocol routines for normal
2177 key exchange and to key agreement packet handling as well.
2179 * Added to both client's and server's KE protocol context the
2180 SilcSKEKeyMaterial pointer to save the key material. We will
2181 bring the key material to the protocol's final callback by doing
2182 this. The final callback must free the key material.
2184 * Added SKE's packet_send callback into client's KE protocol
2185 context so that the caller can choose what packet sending function
2186 is used. This way we can use different packet sending when
2187 doing normal SKE when doing key agreement packet handling (in
2188 the key agreement packet handling we do not want to encrypt
2191 * Implemented the responder side of the key agreement routines
2192 in the client. The client can now bind to specified port and
2193 accept incoming key negotiation. The key material is passed
2194 to the application after the protocol is over.
2196 * Implemented the processing of incoming Key Agreement packet
2197 in the client. Added function silc_client_key_agreement to
2200 * Implemented the intiator side of the key agreement routines
2201 in the client. The client can now initiate key agreement with
2202 another remote client. The key material is passed to the
2203 application after the protocol is over.
2205 * Created client_keyagr.c to include all the key agreement
2208 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2209 SILC_TASK_CALLBACK except that it is not static.
2211 * Created client_notify.c and moved the Notify packet handling
2212 from the client.[ch] into that file.
2214 * Created client_prvmsg.c and moved all private message and
2215 private message key routines from the client.[ch] into that file.
2217 * Create client_channel.c and moved all channel message and
2218 channel private key routines from the client.[ch] into that file.
2220 * Changed silc_client_get_client_by_id_resolve to resolve with
2221 WHOIS command instead of IDENTIFY command, in the file
2222 lib/silclient/idlist.c.
2224 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2226 * Implemented the SKE's responder side to the Client library.
2228 * When FAILURE is received to the protocol do not trust it
2229 blindly. Register a timeout to wait whether the remote closes
2230 the connection as it should do it, only after that process the
2231 actual failure. This was changed to both client and server.
2233 * Added client_internal.h to include some of the structures
2234 there instead of client.h in lib/silcclient/.
2236 * Added function silc_task_unregister_by_callback to unregister
2237 timeouts by the callback function.
2239 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2241 * Some "Incomplete WHOIS info" errors has been appearing on the
2242 log files. Took away the entry->userinfo check from WHOIS
2243 reply sending. The entry->userinfo is now " " if client did not
2244 provide one. I thought this was fixed earlier but something
2245 is wrong still. Let's see if the error still appears.
2247 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * Fixed a minor bug in the login when the channel key is
2250 re-generated in the server. It used to generate the key in
2251 wrong order and thus caused problems in the channel traffic.
2253 * Fixed a minor bug in channel key distsribution after
2254 KICK command. The key was not sent to the router even though
2257 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2259 * Added silc_ske_process_key_material_data as generic routine
2260 to process any key material as the SILC protocol dictates. The
2261 function is used by the actual SKE library but can be used by
2262 applications as well. This relates to the private message keys
2263 and the channel private keys since they must be processed the
2264 same way the normal SILC session keys. The protocol dictates
2265 this. Affected files: lib/silcske/silcske.[ch].
2267 Added also silc_ske_free_key_material to free the
2268 SilcSKEKeyMaterial structure.
2270 * Defined silc_cipher_set_key function to set the key for
2271 cipher without using the object's method function. The affected
2272 files: lib/silccrypt/silccipher.[ch].
2274 * Implemented silc silc_client_add_private_message_key,
2275 silc_client_add_private_message_key_ske,
2276 silc_client_del_private_message_key,
2277 silc_client_list_private_message_keys and
2278 silc_client_free_private_message_keys functions in the
2281 Added functions silc_client_send_private_message_key to send
2282 the Private Message Key payload and silc_client_private_message_key
2283 to handle incoming Private Message Key payload.
2285 * Added Cipher field to the Private Message Key payload to set
2286 the cipher to be used. If ignored, the default cipher defined
2287 in the SILC protocol (aes-256-cbc) is used.
2289 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2291 * Removed lib/silcclient/ops.h file.
2293 Redefined parts of the SILC Client Library API. Created new
2294 file silcapi.h that deprecates the ops.h file and defines the
2295 published Client Library API. Defined also private message key
2296 API and channel private key API into the file.
2298 This is the file that the application must include from the
2299 SILC Client Library. Other files need not be included by
2300 the application anymore.
2302 * Added new key_agreement client operation callback and also
2303 defined the Key Agreement library API for the application.
2305 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2307 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2308 is used by clients to request key negotiation between another
2309 client in the SILC network. If the negotiation is started it
2310 is performed using the SKE protocol. The result of the
2311 negotiation, the secret key material, can be used for example
2312 as private message key.
2314 Implemented the Key Agreement payload into the files
2315 lib/silccore/silauth.[ch].
2317 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2319 * Redefined ciphers for the SILC protocol. Added some new ciphers
2320 and defined the key lengths for the algorithms. Changed the
2321 code accordingly. The default key length is now 256 bits.
2323 * Fixed SKE key distribution function silc_ske_process_key_material
2324 when the key length is more than 128 bits. The default key
2325 length in SILC is now 256 bits.
2327 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2328 to indicate unsupported algorithm.
2330 * Renamed rijndael.c to aes.c and all functions as well.
2332 * Fixed a long standing channel key setting bug in client library.
2333 Weird that it has never surfaced before.
2335 * Fixed bug in channel deletion. If the entire channel is removed
2336 then it must also delete the references of the channel entry
2337 from the client's channel list as the client's channel entry and
2338 the channel's client entry share same memory.
2340 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2342 * Implemented CONNECT and SHUTDOWN commands in the client.
2344 * Implemented CLOSE command to the client.
2346 * Added the function silc_idlist_find_server_by_name into the
2347 files silcd/idlist.[ch].
2349 Added the function silc_idlist_find_server_by_conn into the
2350 files silcd/idlist.[ch].
2352 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2354 * DIE command was renamed to SHUTDOWN. Updated the both code
2357 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2358 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2360 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2363 * Added function silc_server_create_connection function to create
2364 connection to remote router. My server implementation actually
2365 does not allow router to connect to normal server (it expects
2366 that normal server always initiates the connection to the router)
2367 so the CONNECT command is only good for connecting to another
2370 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2372 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2373 or some other client was kicked from the channel.
2375 Implemented the handling of the notify type to both client
2378 Implemented silc_server_send_notify_kicked to send the KICKED
2379 notify. It is used to send it to the server's primary router.
2381 * Implemented the KICK command into server and client.
2383 * Added `query' argument to the silc_idlist_get_client function
2384 to indicate whether to query the client from server or not if
2387 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2388 to indicate that the client is not channel founder.
2392 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2394 * Removed the rng context from SilcPacketContext structure and
2395 changed that the packet routine uses the Global RNG API.
2397 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2399 * Added support for quit message that client can "leave" on the
2400 channel when it quits the SILC. It is ditributed inside the
2401 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2403 Added silc_server_free_client_data that will take the
2404 signoff message as argument.
2406 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2408 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2410 * Updated parts of the protocol specification to keep it up
2413 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2416 payloads in one packet.
2418 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2419 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2420 use now the new List flag.
2422 * Also deprecated the following packet types: REPLACE_ID,
2423 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2425 * Added list support for Notify packet in server.
2427 * Added silc_server_send_notify_channel_change to send the
2428 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2429 the silc_server_send_replace_id.
2431 * Added silc_server_send_notify_nick_change to send the
2432 NICK_CHANGE notify type. Deprecates the function
2433 silc_server_send_replace_id.
2435 * Added silc_server_send_notify_join to send the JOIN notify type.
2436 Deprecates the function silc_server_send_new_channel_user.
2438 * Added silc_server_send_notify_leave to send LEAVE notify type.
2439 Deprecates the function silc_server_send_remove_channel_user.
2441 * Added silc_server_send_notify_cmode and
2442 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2443 types. Deprecates the silc_server_send_set_mode function.
2445 * Added SERVER_SIGNOFF notify type to indicate that server has
2446 quit. This means that all clients on the channel from that
2447 server will drop. This can be also used when netsplit happens.
2449 Deprecated REMOVE_ID packet type since it is not needed anymore
2452 Added silc_server_send_notify_server_signoff to send the
2453 SERVER_SIGNOFF notify type. Deprecates the function
2454 silc_server_send_remove_id.
2456 Added also silc_server_send_notify_signoff to send the
2457 SIGNOFF notify type.
2459 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2460 SILC protocol from this day on. Changed the protocol
2461 specification as well.
2463 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2464 notify type. It is used between routers to notify about
2465 topic changes on a channel.
2467 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2470 * Partly updated the protocol specification to comply with the
2471 changes now made. It is still though a bit outdated.
2473 * The JOIN notify type now takes one extra argument <Channel ID>.
2474 The packet used to be destined to the channel but now the
2475 JOIN type may be sent as list thus it is impossible to
2476 destine it to any specific channel. By adding this argument
2477 it is again possible.
2479 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2481 * Added CREDITS file. The CHANGES and CREDITS file will appear
2482 in the distribution as well.
2484 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2487 types in the server's silcd/packet_receive.c.
2489 * Implemented CMODE and CUMODE to work in router environment.
2491 * Fixed minor encoding and decoding buglet from the
2492 lib/silccore/silcmode.c.
2494 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2497 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2499 * Changed all SilcConfigServer* and silc_config_server* to
2500 SilcServerConfig* and silc_server_config*, respectively.
2503 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2505 * Associated the ID (client or server ID) to the Authentication
2506 Payload to avoid any possibility of forging. Updated the
2507 protocol specification and the code accordingly.
2509 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2511 * The RSA key length is now save to the RsaKey context in the
2512 key generation process in lib/silccrypt/rsa.c. The key length
2513 is now used to figure out the maximum size of the block allowed
2514 to be encrypted/signed.
2516 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2517 is equivalent to the silc_mp_mp2bin but does not allocate any
2520 * Changed silc_mp_mp2bin API to take length argument. If it is
2521 non-zero then the buffer is allocated that large. If zero, then
2522 the size is approximated using silc_mp_sizeinbase, which however
2525 * Created Global RNG API which is global RNG that application can
2526 initialize. After initializing, any routine anywhere in the
2527 code (including library) can use RNG without allocating a new
2528 RNG object. This was done to allow this sort of use of the
2529 RNG in code that has no chance to allocate RNG object. All
2530 applications currently allocate this and many routines in the
2531 library use this. Affected file lib/silccrypt/silcrng.[ch].
2533 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2534 it to use the Global RNG API.
2536 * Defined Authentication Payload into protocol specification that
2537 is used during SILC session to authenticate entities. It is
2538 used for example by client to authenticate itself to the server
2539 to obtain server operator privileges.
2541 Implemented this payload into the lib/silccore/silcauth.[ch].
2542 Implemented also routines for public key based authentication
2543 as the new protocol specification dictates.
2545 Moved definitions of different authentication methods from
2546 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2548 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2549 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2550 silc_pkcs_verify_with_hash functions into the file
2551 lib/silccrypt/silcpkcs.[ch].
2553 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2555 * The client entry's userinfo pointer must be always valid.
2556 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2557 will fail since it requires the userinfo. Now, the userinfo
2558 is allocated as "" if actual userinfo does not exist. Actually,
2559 it must exist and it is totally Ok to drop client connections
2560 that does not announce the userinfo. However, we will make
2561 this workaround for now.
2563 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2564 to return the remote port by socket.
2566 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2568 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2569 SILC_SERVER_PENDING_EXEC and added an new macro
2570 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2571 data or when error occurs while processing the pending command.
2573 Added new argument `destructor' into silc_server_command_pending
2574 and to the SilcServerCommandPending object. This destructor is
2575 now called after calling the pending callback or if error occurs
2576 immediately. If error occurs the actual pending callback won't
2577 be called at all - only the destructor. The destructor may be
2578 NULL if destructor is not needed.
2580 All this applies for client library code as well. Similar
2581 changes were made there as well for the pending commands.
2583 In the client, the application must now allocate the
2584 SilcClientCommandContext with the silc_client_command_alloc
2587 * Added reference counter to the SilcServerCommandContext. Added
2588 function silc_server_command_alloc and silc_server_command_dup
2591 Same type of functions added to the client library for the same
2594 * Removed the cmd_ident from IDListData away since it is now
2595 global for all connections. It is the command identifier used
2596 in command sending and with pending commands. The affected file
2599 * Added reference counter to the SilcSocketConnection objecet to
2600 indicate the usage count of the object. The object won't be
2601 freed untill the reference counter hits zero. Currently only
2602 server uses this, and client ignores it. The client must be
2603 set to use this too later. The affected files are
2604 lib/silccore/silcsockconn.[ch]. Added also the function
2605 silc_socket_dup to increase the reference counter.
2607 This was mainly added because it is possible that the socket
2608 is removed underneath of pending command or other async
2609 operation. Now it won't be free'd and proper DISCONNECTING
2610 flags, etc. can be set to avoid sending data to connection that
2611 is not valid anymore.
2613 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2614 the connection. After that it sets SILC_SET_DISCONNECTED.
2615 It is, however, possible that the socket data is not still freed.
2616 The silc_server_packet_process now checks that data is not
2617 read or written to connection that is DISCONNECTED. The socket
2618 get's freed when the reference counter hits zero.
2620 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2622 * Changed the client operation API: channel_message operation's
2623 `sender' is now the client entry of the sender, not the nickname
2624 and the `channel' is the channel entry, not the channel name.
2626 In the private_message operation the `sender' is now also the
2627 client entry of the sender not the nickname.
2629 Affected file is lib/silcclient/ops.h and all applications
2630 using the client operations.
2632 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * Moved the calling of ops->connect() from connect_to_server_final
2635 into receive_new_id functin since that is the point when the
2636 client is actually allowed to send traffic to network. The
2637 affected file is lib/silcclient/client.c.
2639 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2641 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2642 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2643 (if needs broadcasting) instead of broadcasting the packets one
2644 by one which would make a burst in the network traffic.
2646 * Added `broadcast' argument to the functions in silcd/server.[ch]
2647 silc_server_create_new_channel[_with_id] to indicate whether
2648 to send New Channel packet to primary router.
2650 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Added new function into the silcd/server.[ch] files:
2653 silc_server_create_new_channel_with_id to create new channel with
2654 already existing Channel ID.
2656 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2657 lib/silccore/silcpacket.h. This packet is used t send list of
2658 Set Mode payloads inside one packet. Server uses this to set
2659 the modes for the channels and clients on those channels, that it
2660 announced to the router when it connected to it. The protocol
2661 specification has been updated accordingly.
2663 * The silc_server_new_channel did not handle the packet coming
2664 from normal server as it normally does not send that. However,
2665 when it announces its channels it does send it. Implemented
2666 the support for that.
2668 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2669 into the file lib/silccore/id.h.
2671 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2673 * Fixed memory leaks in the functions silc_idlist_del_client,
2674 silc_idlist_del_channel and silc_idlist_del_server in the file
2675 silcd/idlist.c. All of those leaked like a sieve.
2677 * Fixed some small memory leaks in the client's function
2678 silc_client_notify_by_server.
2680 * Added functions into silcd/server.c: silc_server_announce_clients,
2681 silc_server_announce_channels and silc_server_announce_server.
2682 These functions are used by normal and router server to announce
2683 to its primary router about clients, channels and servers (when
2684 router) that we own. This is done after we've connected to the
2687 These functions effectively implements the following packet types:
2688 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2689 and SILC_PACKET_NEW_ID_LIST.
2691 * Added new functions into the silcd/packet_receive.[ch]:
2692 silc_server_new_id_list, silc_server_new_channel_list and
2693 silc_server_new_channel_user_list to handle the incoming
2694 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2696 * Added support of changing Channel ID in the function
2697 silc_server_replace_id. If the server that announces a channel
2698 to the router already exists in the router (with same name but
2699 with different Channel ID), router is responsible to send
2700 Replace ID packet to the server and force the server to change
2701 the Channel ID to the one router has.
2703 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2704 client that the Channel ID has been changed by the router. The
2705 normal server sends this to the client. Client must start using
2706 the new Channel ID as the channel's ID.
2708 Implemented handling of this new type into lib/silcclient/client.c
2709 into the function silc_client_notify_by_server.
2711 * Added new function silc_idlist_replace_channel_id into the files
2712 silcd/idlist.[ch] to replace the Channel ID.
2714 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2716 * Call silc_server_command_identify_check always when processing
2717 the IDENTIFY command in silcd/command.c
2719 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2722 send keepalive packets. The packet can be sent by clients,
2723 servers and routers.
2725 Added function silc_socket_set_heartbeat into the file
2726 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2727 If not set, the heartbeat is not performed. The actual
2728 heartbeat is implemented in the low level socket connection
2729 library. However, application is responsible of actually
2732 Added silc_server_send_heartbeat to send the actual heartbeat
2733 packet into silcd/packet_send.[ch]. Server now performs
2734 keepalive with all connections.
2736 * Added silc_task_get_first function into lib/silcutil/silctask.c
2737 to return the timeout task with shortest timeout. There was a bug
2738 in task unregistration that caused problems. TODO has been
2739 updated to include that task system must be rewritten.
2741 * The client library will now resolve the client information when
2742 receiving JOIN notify from server for client that we know but
2743 have incomplete information.
2745 * Rewrote parts of silc_server_remove_from_channels and
2746 silc_server_remove_from_one_channel as they did not remove the
2747 channel in some circumstances even though they should've.
2749 * Encryption problem encountered in server:
2751 The LEAVE command used to send the Channel Key packet to the
2752 router immediately after generating it. However, the code
2753 had earlier sent Remove Channel user packet but not immediately,
2754 ie. it was put to queue. The order of packets in the router
2755 was that Channel Key packet was first and Remove Channel User
2756 packet was second, even though they were encrypted in the
2757 reverse order. For this reason, MAC check failed. Now, this
2758 is fixed by not sending the Channel Key packet immediately but
2759 putting it to queue. However, this is more fundamental problem:
2760 packets that are in queue should actually not be encrypted
2761 because packets that are sent immediately gets encrypted
2762 actually with wrong IV (and thus MAC check fails). So, packets
2763 that are in queue should be encrypted when they are sent to
2764 the wire and not when they put to the queue.
2766 However, the problem is that the current system has not been
2767 designed to work that way. Instead, the packet is encrypted
2768 as soon as possible and left to the queue. The queue is then
2769 just purged into wire. There won't be any fixes for this
2770 any time soon. So, the current semantic for packet sending
2773 o If you send packet to remote host and do not force the send
2774 (the packet will be in queue) then all subsequent packets to the
2775 same remote host must also be put to the queue. Only after the
2776 queue has been purged is it safe again to force the packet
2779 o If you send all packets immediately then it safe to send
2780 any of subsequent packets through the queue, however, after
2781 the first packet is put to queue then any subsequent packets
2782 must also be put to the queue.
2784 Follow these rules and everything works fine.
2786 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2788 * Added new function silc_server_remove_clients_by_server to
2789 remove all client entries from ID list when the server connection
2790 is lost. In this case it is also important to invalidate all
2791 client entires as they hold the invalid server entry. This
2792 fixes fatal bug when server has lost connection and will reconnect
2795 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * Made some sanity checks to silc_server_daemonise like to check
2798 whether the requested user and group actually exists.
2800 * Added sanity check to SKE's silc_ske_responder_finish to check
2801 that the public and private key actually is valid.
2803 * Invalidate the client's nickname when receiving Replace ID
2804 packet and the Client ID is being replaced. This means that the
2805 server will query the nickname if someone needs it (client)
2808 * Sort the ID Cache in client library when the ID Cache data
2809 has changed (needs sorting).
2811 * Do not allow for SILC client to create several connections to
2812 several servers. The client does not support windows right now
2813 and generating multiple connections causes weird behaviour.
2815 Irssi-silc client does support windows and can handle several
2816 connections without problems, see: www.irssi.org and SILC plugin.
2818 * Fixed some places where client was added to the IDList. The
2819 rule of thumb is following (in order to get everything right):
2820 If the client is directly connected local client then the
2821 `connection' argument must be set and `router' argument must be
2822 NULL to silc_idlist_add_client function. If the client is not
2823 directly connected client then the `router' argument must
2824 bet set and the `connection' argument must be NULL to the
2825 silc_idlist_add_client function.
2827 * The funtion silc_server_packet_send_local_channel actually did
2828 not check whether the client was locally connected or not. It
2829 does that now. Fixed a bug related to LEAVE command.
2831 * Fixed Remove Channel User payload parsing bug in server's
2832 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2834 * The server's silc_server_save_channel_key now checks also the
2835 global ID list for the channel as it might not be in the local
2836 list. Fixed a bug related to LEAVE command.
2838 * Is this the end of the [<unknown>] buglet that has been lurking
2839 around for a long time? A little for loop fix in server's
2840 silc_server_command_whois_parse that is used by both IDENTIFY
2841 and WHOIS command. At least, this was a clear bug and a cause
2842 of one type of [<unknown>] buglet.
2844 * WHOIS and IDENTIFY commands call the function
2845 silc_server_command_[whois/identify]_check function even if
2846 we are not router server.
2848 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Added --with-gmp configuration option. If set the GMP
2851 is always compiled in the SILC source tree. If not set then
2852 it is checked whether the system has the GMP3 installed. If
2853 it has then the GMP won't be compiled (the system's headers
2854 and library is used), if it doesn't have it then the GMP is
2855 compiled in the SILC source tree.
2857 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Changed RSA private exponent generation to what PKCS #1
2860 suggests. We try to find the smallest possible d by doing
2861 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2862 not security fix but optimization.
2864 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2866 * Added new config entry [Identity] to fork the server and run
2867 it as specific user and group. A patch from Bostik.
2869 * Imported Dotconf configuration library into lib/dotconf.
2870 This will be used to create the SILC configuration files later.
2871 It will appear in the distsribution after this commit.
2873 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2875 * A big code auditing weekend happening. Auditing code for
2876 obvious mistakes, bugs and errors. Also, removing any code
2879 Removed files for being obsolete:
2881 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2882 inline in the file lib/silcutil/silcbuffer.h)
2884 o lib/silcutil/silcbufutil.c (the header has inline versions)
2886 Changed code to fix possible error conditions:
2888 o The buffer formatting routines now check that the destination
2889 buffer really has enough space to add the data. This applies for
2890 both buffer formatting and unformatting
2891 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2892 unformatting was changed to accomodate following rules:
2893 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2894 sent to the function while XXX_*STRING will not allocate or copy
2895 the data into the buffer. Instead it sets the pointer from the
2896 buffer into the pointer sent as argument (XXX_*STRING used to
2897 require that the pointer must be allocated already). This change
2898 makes this whole thing a bit more consistent and more optimized
2899 (note that the data returned in the unformatting with XXX_*STRING
2900 must not be freed now). The routines return now -1 on error.
2902 o Tried to find all code that use buffer_format and buffer_unformat
2903 and added return value checking to prevent formatting and
2904 especially unformatting errors and possible subsequent fatal
2907 o Changed ske->x and ske->KEY to mallocated pointers in
2908 lib/silcske/silcske.h. Fixed possible data and memory leak.
2910 o Added return value checking to all *_parse* functions. Fixed
2911 many memory leaks as well.
2913 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2914 so that buffer overflows would not happen. All code now also
2915 checks the return value as it can fail.
2917 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Added reconnection support to server if the normal server looses
2920 its connection to the router (for example if router is rebooted).
2921 The server performs normal reconnection strategy implemented
2922 to the server. Affected file silcd/server.c.
2924 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2926 * Added new packet type SILC_PACKET_SET_MODE that is used to
2927 distribute the information about changed modes (for clients,
2928 channels and clients channel modes) to all routers in the
2929 network. Updated the protocol specification accordingly.
2931 Added functions into silcd/packet_send.c and
2932 silcd/packet_receive.c: silc_server_send_set_mode,
2933 silc_server_set_mode.
2935 Added new files silcmode.[ch] into lib/silccore that implements
2936 the encoding and decoding of Set Mode Payload. Added new type
2937 SilcSetModePayload. Moved the definitions of different modes
2938 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2940 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2942 * Oops, a little mistake in server's connection authentication
2943 protocol. The protocol is not ended with FAILURE but with
2944 SUCCESS if the authentication is Ok. :) Affected file is
2947 * Implemented NICK_CHANGE notify handling in server in the file
2948 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2949 the local clients on the channel. After the changing nickname
2950 in router environment snhould work and the [<unknown>] nickname
2951 should appear no more.
2953 The silc_server_replace_id function that receives the Replace ID
2954 payload now sends the NICK_CHANGE notify type also in the file
2955 silcd/packet_receive.c
2957 * Changed WHOIS and IDENTIFY command to support the maximum amount
2958 of arguments defined in protocol specs (3328 arguments). This
2959 fixed a bug that caused problems when there were more than three
2962 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * Added extra parameter, command identifier, to the
2965 silc_client_send_command so that explicit command identifier
2968 Changed that ID list routines uses specific command identifier
2969 when sending WHOIS/IDENTIFY requests to the server so that they
2970 can be identified when the reply comes back.
2972 Affected files lib/silcclient/command.[ch],
2973 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2975 * Added `sender' argument to silc_server_packet_send_to_channel
2976 to indicaet the sender who originally sent the packet to us
2977 that we are now re-sending. Ignored if NULL. Affected file
2978 silcd/packet_send.[ch].
2980 * Added some server statistics support in silcd/server_internal.h
2981 SilcServerStatistics structure and around the server code. Also
2982 send some nice statistics information when client is connecting
2985 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2987 * Fixed channel ID decoding in server's JOIN command reply in
2988 silcd/command_reply.c
2990 * Fixed braodcasting of replace ID payload to not to send it if
2991 we are standalone server in silcd/packet_receive.c.
2993 * Fixed all channel message sending routines to not to send
2994 packets to clients that has router set, since they are routed
2995 separately in the same function earlier. Affects file
2996 silcd/packet_send.c and all channel packet sending functions.
2998 * In USERS reply, res_argv[i] are not allocated, the table
2999 is allocated. Thus changed that free the table, not its
3002 * In server's whois_check and identify_check if the client is
3003 locally connected do not send any WHOIS commands - they are not
3006 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Fixed some minor bugs in client when sending WHOIS command. The
3009 arguments was in wrong order.
3011 * Removed statis function add_to_channel from server in
3012 silcd/command.c that was previously used with the joining but
3015 * Tested USERS command in router environment successfully with two
3016 routers, two servers and two clients.
3018 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3020 * Reorganized the USERS command and command reply in client library
3021 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3022 When the command is given by user we register a pending command
3023 callback that will reprocess the command after the reply has been
3024 received from the server. When reprocessing the packet we then
3025 display the information. Thus, the USERS information is displayed
3026 now in the command callback instead of in the command reply
3027 callback. The processing of the command is same as previously
3028 when server has sent the command reply in the JOINing process.
3030 * Added to USERS command in silcd/command_reply.c to join the client,
3031 we didn't use to know about, to the channel after we've created
3032 a client entry for it. Also, for clienet we did know already still
3033 check whether it is on the channel or not and add it if not.
3035 * Removed silc_server_command_join_notify as the function and its
3038 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3040 * Changed the client's pending command handling to the same as the
3041 server's pending command handling. It is also now possible to
3042 execute command reply functions from other command reply
3043 function as the function callbacks for commands and command
3044 replies are one and same. The pending commands are not static
3045 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3046 in client connection context. Thus, pending commands are server
3047 connection specific as it is convenient.
3049 Changed the function silc_client_command_pending and
3050 silc_client_command_pending_del and added new function
3051 silc_client_command_pending_check. Removed the
3052 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3055 * Added cmd_ident, current command identifier, to the client
3056 connection context in lib/silcclient/client.h to keep track on
3057 command identifiers used in command sending. Client's command reply
3058 function handling now supports the mandatory command identifiers.
3060 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3061 funtions in client to fully support pending command callbacks.
3063 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3064 as one of the arguments to the application in the command reply
3067 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3068 before first releasing SILC but came back. Now it is removed again
3069 and should come back nomore. The FORWARDED flag was used only
3070 by the JOINing procedure by forwarding the command packet to router.
3071 Now, the JOINing procedure has been changed to more generic (due
3072 to various router environment issues) and FORWARDED is not needed
3073 anymore for anything. The protocol specification is yet to be
3076 Now, removed silc_server_packet_forward from server and the flag
3077 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3079 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3081 * Renamed NAMES command to USERS command. The NAMES was named that
3082 due to historical reasons. Now it is renamed. Also, rewrote
3083 parts of the USERS command. The nickname list is not sent anymore
3084 by the server. Only Client ID and mode lists are sent in the USERS
3085 command. Changed this also to the protocol specification.
3087 The client now resolves the names and stuff after it receives
3088 the USERS list from the server when joining to the channel.
3090 * WHOIS and IDENTIFY commands has been changed to support multiple
3091 Client ID's per command. One can now search for multiple users
3092 in the network by sending only one WHOIS or IDENTIFY command.
3093 Changed the code and the protocol specifications.
3095 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3096 uses silc_server_command_whois_parse to parse the request. */
3098 * If normal server, do not parse the WHOIS and IDENTIFY requests
3099 before sending it to the router. Saves some time.
3101 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * Fixed JOIN command on client library. Wrong number of arguments
3104 used to crash the client.
3106 * Added silc_server_channel_has_global function to check whether
3107 channel has global users or not.
3109 * Added silc_server_channel_has_local function to check whether channel
3110 has locally connected clients on the channel.
3112 * The silc_server_remove_from_one_channel now checks whether the
3113 channel has global users or not after given client was removed from
3114 the channel. It also checks whether the channel has local clients
3115 on the channel anymore. If it does not have then the channel entry
3116 is removed as it is not needed anymore.
3118 * The silc_server_notify now checks on JOIN notify whether the joining
3119 client is one of locally connected or global. If it is global then
3120 the channel has now global users on the channel and that is marked
3121 to the channel entry. Also, it now saves the global client to
3122 global list who is joining and JOINs it to the channel. This is
3123 for normal server, that is.
3125 Changed silc_server_send_notify_on_channel,
3126 silc_server_packet_relay_to_channel and
3127 silc_server_packet_send_to_channel check if we are normal server
3128 and client has router set (ie. global client) do not send the
3129 message to that client, as it is already routed to our router.
3131 * Implemented LEAVE notify type handling in silc_server_notify
3134 * Tested LEAVE command in router environment successfully. Tested
3135 with two routers, two servers and two clients.
3139 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3141 * Implemented SIGNOFF notify type handling in silc_server_notify
3144 * silc_server_remove_id now removes the client entry from all channels
3145 it has joined and thusly sends SIGNOFF notify type.
3147 * Rewrote the NAMES list generation in server by removing two excess
3148 loops. The lists are created now inside one loop.
3150 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * silc_server_remove_channel_user checks now also global list
3153 for channel and client.
3155 * silc_server_new_channel_user checks now both local and global
3156 list for channel and client. Fixed a bug in client id decoding.
3157 Used to decode wrong buffer.
3159 * silc_server_channel_message checks now both local and global
3160 list for channel entry.
3162 * Tested channel joining (hence JOIN) in router environment
3163 successfully. Tested with two routers, two servers and two
3166 * Tested channel message sending in router environment successfully.
3168 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3170 * Added silc_server_save_channel_key into server.[ch] to save the
3171 received channel key in Channel Key payload processing. It is
3172 also used in JOIN command reply handling.
3174 Equivalent function silc_client_save_channel_key added into
3175 client.[ch] into client library.
3177 * Changed JOIN command reply to send information whether the channel
3178 was created or not (is existing already) and the channel key
3179 payload. Changed protocol specs accordingly.
3181 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3182 the request was sent by ID and not by nickname. Crashed on
3185 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3187 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3188 now correctly save the received data.
3190 * silc_server_free_sock_user_data now notifies routers in the
3191 network about entities leaving the network.
3193 At the same time implemented functions silc_server_remove_id
3194 and silc_server_send_remove_id to receive and send REMOVE_ID
3195 packets. The packet is used to notify routers in the network
3196 about leaving entities. The ID removed will become invalid in
3199 * Added function silc_idlist_del_server into server. Removes and
3200 free's server entry from ID list.
3202 * silc_server_private_message function now checks, if we are router,
3203 that the destination ID really is valid ID, naturally.
3205 * In router when NEW_ID packet is received (for new client) the
3206 hash of the Client ID is saved in the ID Cache but the
3207 client->nickname is set to NULL, instead of putting the hash
3210 IDENTIFY command now also checks that client->nickname must be
3211 valid. If it is not if will request the data from the server who
3212 owns the client. Added new function
3213 silc_server_command_identify_check.
3215 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3216 to set the command to already allocated Command Payload.
3218 * Tested private message sending in router environment with two
3219 routers, two servers and two clients. Fixed minor bugs and now
3222 * Fixed segfault from client's NAMES command. Used to crash if
3225 * Forwarded packets must not be routed even if it is not destined
3226 to the receiver. Changed server code comply with this.
3228 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3230 * Added `require_reverse_mapping' boolean value to ServerParams
3231 structure. If TRUE (not default) the server will require that
3232 the connecting host has fully qualified domain name.
3234 If the reverse mapping is not required and hostname could not be
3235 found the IP address is used as hostname.
3237 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Implemented version string checking to both client and server.
3240 The check is incomplete currently due to the abnormal version
3241 strings used in development version of SILC.
3243 * Changed all command functions in server to use the new
3246 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3248 * Changed char *data to unsigned char *data in ID Cache system to
3249 support binary data as ID Cache data. Changed code to support
3250 binary data in lib/silccore/idcache.c.
3252 * Renamed silc_server_packet_relay_command_reply to
3253 silc_server_command_reply as it is normal packet receiving
3254 function. Rewrote the function to accept command replys for
3255 servers and not only for clients.
3257 * Mark remote router always as registered server if we are connecting
3258 to it. Otherwise, commands sent by the router to us are ignored.
3260 * All ID List find routines now returns the ID Cache Entry pointer
3261 as well if requested.
3263 * WHOIS command works now in router environment, tested with two
3264 routers, two servers and two clients.
3266 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3267 in router environment (as it is almost equivalent to WHOIS) but
3268 hasn't been tested thoroughly. Added new functions:
3270 silc_server_command_identify_parse
3271 silc_server_command_identify_send_reply
3272 silc_server_command_identify_from_client
3273 silc_server_command_identify_from_server
3275 * Disabled route cache adding because adding two different ID's with
3276 same IP replaces the old cache entry thus giving wrong route.
3277 The entry->router->connection is always the fastest route anyway
3278 so route cache may not be needed. Of course, new routes maybe
3279 established after receiving the ID when the entry->router->connection
3280 might not be anymore the most optimal.
3282 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Add route cache for received ID for fast routing.
3286 * Added silc_server_packet_route to route received packet on router
3287 that is not destined to us.
3289 * Renamed silc_server_get_route to silc_server_route_get.
3291 * Added id_string and id_string_len fields into SilcServer to
3292 include encoded ServerID for fast comparing without excess
3293 encoding of the ID's.
3295 * Cleaned up WHOIS command on server side. Added following static
3298 silc_server_command_whois_parse
3299 silc_server_command_whois_check
3300 silc_server_command_whois_send_reply
3301 silc_server_command_whois_from_client
3302 silc_server_command_whois_from_server
3304 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3305 arguments in command replies. All command functions should be
3306 updated to use this macro.
3308 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Minor typo fixes on command reply handling on server.
3312 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Added silc_server_command_add_to_channel internal routine to add
3315 the client to the channel after router has created the channel and
3316 sent command reply to the server.
3318 * Added generic silc_server_send_command to send any command from
3321 * Use static buffer with ID rendering instead of duplicating data.
3323 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Fixed a channel user mode bug when joining to a channel server gave
3326 everybody channel founder rights, oops.
3328 * We mark ourselves as the router of the incoming server connection
3329 if we are router ourselves. This way we can check in some packet
3330 sending functions whether it is locally connected server. For
3331 incoming router connections we put NULL.
3333 * For router sending packets locally means now always sending the
3334 packet cell wide; to local clients and local servers. For normal
3335 server sending packet locally means sending it to only local
3338 * Fixed the JOIN command to really work in router environment. If the
3339 channel is created it is always created by the router. Router is
3340 also responsible of making the initial joining to the channel,
3341 sending JOIN notify to the sending server and distributing
3342 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3343 does not exist server doesn't do anything else but forward the
3344 command to the router which performs everything.
3346 * Added silc_server_send_channel_key function to send the Channel Key
3349 * Added silc_server_create_channel_key to create new channel key. The
3350 channel key is now re-generated everytime someone joins or leaves
3351 a channel, as protocol dictates. Note: channel->key_len is the
3354 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3356 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3357 packet_receive.[ch] to separate packet sending and receiving
3358 routines. The server.[ch] now includes everything else including
3359 actual packet processing (writing and reading data) and other
3362 Renamed silc_server_private_message_send_internal to
3363 silc_server_send_private_message. The routine is still though
3364 used only to relay private messages as server does not send
3365 private messages itself.
3367 Renamed silc_server_new_channel to silc_server_create_new_channel
3368 and added new function sicl_server_new_channel that handles the
3369 incoming New Channel packet. Added also new sending function
3370 silc_server_send_new_channel to send New Channel Payload.
3372 * Added new function silc_server_notify to process incoming notify
3373 packet to the server/router. Server may then relay the notify
3374 to clients if needed.
3376 * Added new function silc_server_new_channel_user to process incoming
3377 New Channel User packet. Router will redistribute the packet and
3378 send JOIN notify to its local clients and locally connected servers
3379 if needed. Normal server will send JOIN notify to its local client
3380 on same channel when received this packet. Added also corresponding
3381 sending function silc_server_send_new_channel_user to sent the
3384 * Added boolean route argument to send_notif_to_channel and
3385 packet_send_to_channel functions to attempt to route the packet
3386 if it is TRUE and send only locally if it is FALSE.
3388 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * silc_server_replace_id now broadcasts the received replace ID
3391 packet if it is not broadcast packet already. The router must
3392 broadcast to inform other routers about changed ID.
3394 * Added backpointer to server's router into SilcServer context in
3395 silcd/server_internal.h.
3397 * Fixed silc_server_packet_broadcast to send correct broadcast
3400 * The channel key is now distributed to the local client as soon
3401 as it is received from the router (in router environment) so that
3402 no other packet may be sent for the channel until client has
3405 * silc_server_remove_channel_user now broadcasts the received
3406 Remove Channel User packet if it is not broadcast packet already.
3407 The router must broadcast to inform other routers about removed
3410 * Added users field into SilcPacketContext that is a reference count
3411 of the context. One can increase the reference count by calling
3412 silc_packet_context_dup which is now changed to just increase the
3413 reference count instead of duplicating the data. The reference
3414 count is decresed by calling silc_packet_context_free that will
3415 free the data after the reference count hits zero.
3417 For now on the packet context and everything allocated into it
3418 (including the raw packet from network) must be freed by calling
3419 the new silc_packet_context_free function. Added also new function
3420 silc_packet_context_alloc that must be used now to allocate the
3421 context. This also means that if a routine is asynchronous from
3422 silc_[client/server]_packet_parse_type the packet context must
3423 be duplicated by calling silc_packet_context_dup. Otherwise it
3424 gets free'd after silc_[client/server]_packet_parse_type returns.
3425 Also, one must remember that if packet is duplicated then its
3426 reference count must be decresed by calling the free function as
3427 many times as it was duplicated.
3429 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3430 from both client and server.
3432 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3434 * Made joining to a channel working in router environment.
3436 * Cleaned up JOIN command on server side and create function
3437 silc_server_command_join_channel internal routine to make the
3440 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Changed silc_command_pending list to SilcDList. Also, added
3443 `ident' field to SilcServerCommandPending structure to identify
3444 the reply and to call correct callback.
3446 Added silc_server_command_pending_check function to replace the
3447 corresnponding macro. The silc_command_pending list is not
3450 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3451 to set identifier to previously allocated Command Payload. It
3452 is used to set identifier for command when resending Command
3455 * Added silc_command_payload_encode_payload to encode Command
3456 Payload buffer from SilcCommandPayload structure.
3458 * Added silc_argument_payload_encode_payload to encode Argument
3459 payload buffer from SilcArgumentPayload structure.
3461 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Changed WHOIS command to support router connection on server side.
3464 The whois request is always sent to router unless the server is
3465 standalone server. After server has received the reply from the
3466 router will it send the reply to the client.
3468 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3469 broadcast received broadcast packet. The function is used only
3470 by router. The broadcast packet is always sent to the router's
3473 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3474 render given ID to printable string, for log files for example.
3476 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Made basic router to router connections working. At least they
3479 can now connect to each other but nothing really works the way
3480 they are supposed - yet.
3482 * Added new initiator token to RouterConnection configuration
3483 file in silcd/serverconfig.[ch]. It is used to tell whether we
3484 are the initiator to the remote router or whether we'll expect
3485 the other end to connect.
3487 * Moved registering of listener task to silc_server_init, hence
3488 the server starts listenning as soon as it is run, even if it
3489 does not have connections to other routers. Let's see how well
3492 * Changed default connection retry timeouts for more suitable in
3495 * Removed cipher and such arguments from silc_idlist_add_client
3496 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3497 Added new function silc_idlist_add_data to add the keys and stuff
3500 * Added SilcIDListData structure and added it to SilcClientEntry
3501 and SilcServerEntry as their first field in the structure. This
3502 way we can explicitly cast the ID entries to the SilcIDListData
3503 structure and get common data for the entries. In past, we had
3504 to first check what type of connection it is and then cast it to
3505 correct ID entry type. Now, we can directly cast the opaque
3506 pointer to the SilcIDListData (no matter what ID entry it actually
3507 is) and get the data needed.
3509 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3512 in some circumstances even if threre were timeout tasks, though not
3513 IO tasks, but tasks anyway. Now fixed.
3515 * Defined SilcServerConnection structure to hold connection specific
3516 stuff about directly connected servers and routers. The definition
3517 is currently in silcd/server_internal.h. I thought about having
3518 a bit more important role fro this struct but for now it is used
3519 only when connecting to other server (or router actually).
3521 * Added connecting retry support in server when connecting to
3522 router(s). The retry feature implement exponential backoff
3523 algorithm. Also, added SilcServerParams structure to hold default
3524 parameters for server. For now, it include these retry settings
3525 and are hard coded. After server is moded to be as Silc Server
3526 Library this structure will be more important.
3528 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Changed client librarys channel->clients table to SilcList and
3531 changed code accordingly.
3533 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Changed client's channel table to SilcList and changed code
3536 accordingly. Also changed SilcChannelClientEntry to include back-
3537 pointer to the channel so that client entry can use that structure
3538 as list as well and we have fast cross-reference to the channel.
3539 This change dramatically decreased the complexity of channel
3540 handling with client entry and vice versa (removed one extra
3541 loop when searching for channel entry from many functions).
3543 * Changed server->sim from table to SilcDList and changed code
3546 * NAMES command can now be used from user interface. It will show
3547 the user list on the channel, neatly.
3549 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3550 Code now saves realname of the user if it becomes available.
3552 * Renamed configure.in to configure.in.pre and made ./prepare
3553 script to automatically add correct version string to
3554 configure.in which it creates from configure.in.pre.
3556 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * NAMES command reply now shows users mode with the nickname when
3561 * Moved silc_client_ch[u]mode[_char] functions from
3562 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3563 place sucks, they are utility functions and should be in some
3566 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3568 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3571 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3575 * Added TRQ (efficient deque and list library) into lib/trq. This is
3576 a very good list library that is currently used in the SILC. Defined
3577 SilcList API over the library because I didn't like the API very
3578 much. See lib/trq/silclist.h for the API and examples of how to
3579 use the API. Fixed various places in the code to use the new
3580 SilcList API. The SilcList is meant for lists that has a structure
3581 already defined as a list. It is not suitable to add just some
3582 context to the list (in TRQ, the context is the list actually).
3584 So, I defined SilcDList that can be used for the purpose where
3585 predefined list structure does not exit. This can be used as
3586 such list. Now some context just can be added to the SilcDList.
3587 Currently this list is not used in the SILC just yet, though there
3588 are a lot places where this can replace dynamically allocated
3589 tables and I will fix these places, later, to use SilcDList.
3590 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3591 and use TRQ internally).
3593 Also fixed some annoying warning messages that the original TRQ
3594 code generated. Also minor changes to TRQ's Makefile.in.
3596 * Added support for querying by Client ID to both WHOIS and
3597 IDENTIFY commands into server, as required by the protocol.
3599 * Removed method function pointers from SilcBuffer structure. They
3600 weren't used to anything and just increased the context size for
3601 no good reason. This change also made silc_buffer_alloc and
3602 silc_buffer_free functions inline functions.
3604 * Disabled command flooding detection support until it's fixed so
3605 that it accepts commands in but does not execute them more than once
3608 * Added silc_net_localhost(), to return local hostname, into
3609 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3610 that must be initialized before calling silc_client_init.
3612 * Added new function: silc_server_send_notify_on_channels to send
3613 notify messages to all channels client has joined. It is assured
3614 that the message is sent only once per client.
3616 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3617 lib/silcutil/silcutil.[ch] as silc_format function. The new
3618 function is generic and is used by server as well, not only by
3619 the logging routines.
3621 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3622 the provided version string was not acceptable. Added new function:
3623 silc_ske_check_version into lib/silcske/silcske.h. The function
3624 must be implemented by the application (client or server) and it
3625 does not reside in the SKE library. The function checks the version
3626 string remote end sent.
3628 * Added back pointers (to opaque context and to SilcSocketConnection)
3629 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3631 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3632 duplicate packet context structure.
3634 * Changed `notify' client operation to send same arguments as client
3635 receives from server except for ID's. ID's are mapped to correct
3636 ID entry and that is returned. Also, if channel entry is not sent
3637 by server but the notify is for channel the channel entry is sent
3638 to application (otherwise application doesn't know that it is for
3639 channel (library gets it from packet's Destination ID)).
3641 * Added silc_client_remove_from_channels into client library to
3642 remove a client from all channels it has joined to. Used when
3643 received SIGNOFF notify from server. Added also new function
3644 silc_client_replace_from_channels to replace old ID entry with
3645 new ID entry on all channels. Used when received NICK_CHANGE
3648 * Fixed ID Cache list handling in silc_idlist_get_client in
3649 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3650 to get (or query) client by ID.
3652 * Updated TODO list.
3654 * Added connection authentication status message defined by the
3655 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3656 support for these into the code in client and server side.
3658 * Added generic function silc_client_send_command to send any command
3659 with variable argument list. Application should use this function
3660 to send commands if the command functions provided by the library
3661 does not suite for the application's user interface needs.
3663 * Added new `failure' client operation. Application is notified about
3664 received failure packet if client is executing a protocol. In this
3665 case the protocol's execution has failed.
3667 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3668 is required by the protocol.
3670 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3671 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3674 * Added status flag to SilcSKE object to indicate realtime status
3675 of the SKE protocol.
3677 * Application receives now exactly same command reply arguments as
3678 the library receives from server. However, if ID is received the
3679 corresponding ID entry is returned to the application (eg. Client
3680 ID is mapped to correct SilcClientEntry entry and that is returned).
3681 Changed command_reply client operation due to this change.
3683 * Changed all ID's in commands and in command replys as ID Payloads.
3684 Change affected both client and server side codes.
3686 All ID's sent in SILC network (with execption of ID's in SILC
3687 Packet header) are sent in ID Payload to support variable length
3690 * Server now notifies nick changes and notifies all clients on
3691 the channels about the new nickname (about the new Client ID,
3694 * Implemented CMODE command to change channel modes. Supports all
3695 channel modes defined by the protocol specs except ban and invite
3696 lists. (Also, private channel key mode is supported but support for
3697 setting private channel key in client is missing, thus, this mode
3698 has no effect on client side (except that server requires that the
3699 client uses private channel key and normal channel traffic does not
3702 Also, invite mode works per se, but INVITE command does not work
3703 yet correctly, so you can set channel as invite only channel but
3704 inviting clients to the channel does not work (it is yet to be
3705 thought what's the best way to do it).
3707 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3708 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3709 Implemented CUMODE command to change user's mode on the channel.
3710 Supports all modes defined by the protocol specs.
3712 * Added NAMES command reply to return users modes on the channel.
3714 * Removed unnecessary and slow ciphers from lib/silccrypt.
3716 * Set SO_KEEPALIVE option to connection sockets by default.
3718 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3720 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3721 redefined the Notify Payload into protocol specs.
3723 * Added silc_id_payload_parse_id to get ID directly from raw
3726 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3728 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3729 accept searching by Client ID as well.
3731 * Added support for LEAVE and SIGNOFF notify types in client library.
3733 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3734 to parse ID Payload from raw data.
3736 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Added flags parameter into silc_ske_assemble_security_properties
3739 function in lib/silcske/silcske.[ch].
3741 * Changed notify client operation to fit better for notify messages
3742 sent by server. The notify payload received from server is now
3743 passed to the application (after parsing it to SilcNotifyPayload).
3744 It is application's responsibility to retrieve the arguments
3745 from the payload and show the message the way it wants. The message
3746 sent by server is implementation specific.
3748 * Changed public keys to comply with the protocol specification.
3749 Old public keys are not supported anymore and are not compatible.
3751 * Removed nickname from Channel Payload as the latest draft removed
3752 it. The client must resolve the nickname from the NAMES command
3753 reply received when it joined the channel.
3755 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3757 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3759 * Fixed some errors in protocol specification drafts.
3761 * Created lib/silccore/silcnotify.c to implement Notify Payload
3762 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3763 generic payloads described by protocol specifications. The file
3764 includes implementations for ID Payload and Argument Payload.
3766 * Changed Command Payload implementation to use the new Argument
3767 Payload. Changed command_xxxx_payload to command_payload_xxxx
3768 to comply with SILC coding conventions.
3770 * Added suppport for Argument Payload handling in Notify Payload
3771 implementation as protocol requires it. Added the new support
3772 into server and client lib as well.
3774 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Added support for multiple nicknames on same channel. [n] is
3777 added locally to the nickname if there are more than one same
3778 nicknames on the channel.
3780 * Server now sends all nicknames that matched WHOIS request.
3781 Client also shows the list received from server.
3783 * Added TOPIC command to client side. User can now set and show
3784 current topic on channel.
3786 * Added MOTD command to client and server. Also, server sends the
3787 motd when client connects to the server.
3789 * Changed version strings to comply ISO 8601.
3791 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Fixed protocol error handling in client library. It should now
3794 cope even if the SKE fails for some reason.
3796 * Made new protocol specification drafts for submitting to IETF.
3798 * Implemented TOPIC command to server in silcd/command.c.
3800 * Added two new notify types into lib/silccore/silcnotify.h:
3801 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3802 notify nickname change and topic setting/change on a channel.
3804 * API change of command_reply operation in client library. The
3805 application gets now the status type received from server as well.
3807 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3811 * Cras fixed and optimized the packet handling even further and
3812 it should work now. Minor change to the prototype of function
3813 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3815 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Added new function into lib/silcutil/silcschedule.[ch]:
3818 silc_schedule_with_fd to select() a specified fd. The function
3819 returns after timeout expires or data arrives or goes. The
3820 function is used by packet routines to wait that all data is
3821 received from network.
3823 * Fixed data reading from network in lib/silccore/silcpacket.c.
3824 The code now assures that all data is read from the fd and then
3825 continues packet processing. This was a bug fix since the code
3826 used to drop some data in some circumstances.
3828 * Added new function into lib/silcclient/client.[ch]:
3829 silc_client_start_key_exchange to start key exchange after
3830 connection has been established to server. The code internally
3831 now uses this funtion but its main purpose was to provide it
3832 for applications that perform their own connecting. After
3833 application has created a connection it merely calls this
3834 function to start the key exchange between client and server.
3835 The library takes care of everything else after that.
3837 Updated also lib/silcclient/README to explain the usage of
3840 * Do not send to application information that connection has
3841 been established. Application gets notified it by connect
3844 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * Applied cras's patch to add silc_schedule_one function. The
3847 function runs scheduler once and returns.
3849 * Fixed the scheduler after cras messed it up. The timeout
3850 handling works now as it's supposed to work.
3852 * Added into lib/silccore/ silcnotify.h to include notify
3853 message types support. Changed silc_server_send_notify*
3854 functions, in server.[ch], to support those new notify types.
3855 Added the support for the notify types into client library,
3856 as well. Added new notify client operation into ops.h in
3859 * Changed silc_server_packet_send_to_channel to send normal
3860 packets instead of just channel message packets. The function
3861 is now used to send the notify packets to channels. It is not
3862 used to send channel message packets anymore, as server never
3865 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3866 va_arg()s as it seems to require it nowadays. I guess, if SILC
3867 is compiled with older va_arg() the new code should work anyway.
3869 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Splitted core library. Core library (lib/silccore) includes
3872 now only SILC protocol specific core (and common) components.
3873 Created new utility library (lib/silcutil) that includes more
3874 generic purpose stuff. The stuff for util library was taken
3875 from the old core library. This was minor and easy split.
3877 * Created SILC Client Library (lib/silcclient) that includes
3878 implementation of the SILC client without user interface. This
3879 was major move from silc/ directory. The code has been changed
3880 so that it is transparent towards the user interface. The
3881 silc/ directory includes now the same user interface as before
3882 and it uses the new client library. Read lib/silcclient/README.
3883 Basicly, the client library performs everything else related
3884 to SILC except user interface handling. Also, configuration
3885 files are considered to be part of user interface and library
3886 does not handle them.
3888 This change also changed a lot of structures, function naming etc.
3889 Most important change was that SilcClientWindow object was
3890 renamed to SilcClientConnection in the client library. Created
3891 also new file lib/silcclient/ops.h. Also added new files
3892 silc/local_command.[ch] and silc/client_ops.[ch].
3894 All these changes were made to make it easier for user interface
3895 designers to create what ever user interface for the SILC client
3898 It is also expected that the server will be moved to lib
3899 directory as well and SILC Server Library will be created;
3900 sometimes in the future.
3902 * Removed Local commands from lib/silccore/silccommand.h as
3903 they are application specific and new client library does not
3904 handle any of those anymore.
3906 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3907 old client implementation in silc/.
3909 * Added support for callback functions in SILC_LOG_* macros.
3910 Application can now set its own callbacks that will be called
3911 instead of using the default functions that will always print
3912 the debug messages to stderr (or stdout). Also, debugging can
3913 now be disabled by setting silc_debug to FALSE and re-enabled by
3914 setting it to TRUE. Note, that logging will still work even
3915 if debugging is disabled.
3917 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3918 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3919 silc_log_reset_debug_callbacks.
3921 * To enable debugging in silc client one must give now -d
3922 option on command line.
3924 * Changed silc_schedule_init to automatically allocate task queues
3925 if they are not allocated before calling it.
3927 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Added GMP 3.1 into math library.
3931 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3934 a channel in SILC network. The packet is used by servers and
3935 routers to notify other routers that user has left a channel.
3936 This little feature was missing until now. Added the feature
3937 to protocol specification as well.
3939 Added functions: silc_server_send_remove_channel_user and
3940 silc_server_remove_channel_user into server.[ch].
3942 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3943 lib/silccore/silcpacket.h. However, they are not implemented
3946 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Fixed joining to a channel and sending channel messages
3949 between server and router. The channel message sending should
3950 now work inside a cell.
3952 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3954 * Fixed the private message sending between server and router.
3955 The private message sending should now work inside a cell.
3957 * Added silc_server_replace_id into server.[ch] to replace
3958 existing ID in the SILC network.
3960 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3961 and silc_idlist_replace_server_id into idlist.[ch] in server.
3963 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Fixed the server to server connections. Server can again now
3966 connect to router. Router to router connections probably does
3969 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Added dynamic protocol registering support. Now protocols can
3972 registered and unregistered on the fly. Patch by cras.
3974 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Added lib/contrib directory to hold routines that some platforms
3977 don't have but are needed by SILC.
3979 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3980 into lin/contrib to provide getopt() and getopt_long() for
3981 those who don't have it.
3983 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Added AWAY command to client. When away message is set and
3986 client receives a private message packet the client automatically
3987 replies to the sender with the away message.
3989 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3990 bug seemed to be the cause of recent problems when compiling
3993 * Added version detection support to SKE protocol specification
3994 and added the new changes to the SKE implementation as well.
3995 There were other minor changes in the SKE protocol as well.
3997 Many changes in lib/silcske/silcske.[ch] and in
3998 lib/silcske/payload.[ch].
4000 * Added ^U functionality, clear input line. Patch from cras.
4002 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4004 * Mainly small bugfixes on core library. Fixed some debugging
4005 logging and buffer overflow in silclog.c.
4007 * Updated config.sub and config.guess on the distribution tree.
4009 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4011 * Added command lagging support in server. Client may execute
4012 commands now only once in two seconds.
4014 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Optimized packet reception. MAC computation and checking is now
4017 also more optimized. A lot previously duplicated code is now
4018 used as generic by both client and server.
4020 * Fixed key pair generation in clientutil.c
4022 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Added into lib/silccore/silcbufutil.[ch] new function;
4025 silc_buffer_realloc.
4027 * Moved generic packet sending/encryption functions to
4028 lib/silccore/silcpacket.[ch] from client and server. Some
4029 rewriting of the functions.
4031 * Moved all generic packet reception/decryption functions to
4032 lib/silccore/silcpacket.[ch] from client and server. The
4033 packet processing is now much cleaner in both client and server.
4034 These were major changes in both client and server.
4036 * Created many common functions in server to do packet sending.
4037 Previously code were duplicated a lot, this has been removed
4040 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Rewrote major parts of the ID cache system. Don't know
4043 whether it is better now or not but at least the API is more
4046 * Major rewrite on ID cache stuff on client because of the ID
4047 cache API changes. Added idlist.c to client.
4049 * Also major rewrite on ID cache stuff on server as well.
4050 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4051 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4052 in hand, instead they are all put into the ID cache system now.
4053 All server_idlist_* routines uses ID cache now instead of
4054 traversing its own lists (those lists does not exist anymore).
4055 SilcIDList though still exists. Also, SilcXXXEntry's are
4058 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Finally made the SKE implementation compliant to the protocol
4061 specification. All mp integers are now binary encoded as
4062 opposed being HEX encoded.
4064 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4067 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4068 functions: silc_[encode/decode]_pem. Also added function
4069 silc_encode_pem_file to PEM encode with newlines ('\n') for
4072 * SILC public keys are now encoded either PEM or binary. Same
4073 option is for private keys as well. By default private keys
4074 are binary encoded and public keys PEM encoded. Silly HEX
4075 encoding were removed.
4077 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4078 function to create fingerprints.
4080 * Fixed a bug in SHA1; does not change the original data anymore.
4082 * Partly implemented INFO command on client and server side.
4083 Fixed CLEAR command. Changes to SERVER command; show current
4084 server(s) when giving command without arguments. Added
4085 VERSION command to client.
4087 * Added check to server that unregistered connections cannot
4088 execute commands (unless it is specificly allowed).
4090 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * Fixed screen refresh.
4094 * Fixed channel joining bug from client. On some circumstances
4095 client tried to join to a channel it had already joined.
4097 * Added public key verification process into client's protocol.c.
4098 The client now verifies the public key from user and saves
4099 it into ~./silc/serverkeys/ directory.
4101 Added into: clientutil.[ch]: silc_client_verify_server_key.
4103 * Changed SKE protocol's silc_ske_initiator_finish function
4104 to accept callback function that verifies the received public
4105 key. Removed old silc_ske_verify_public_key function.
4107 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4110 silc_pkcs_private_key[_data]_set.
4112 * Made the password and public authentication more cleaner in
4113 server's protocol.c.
4115 * Removed historic and obsolete protocol `channel_auth' from
4116 both client and server.
4118 * Removed wrong way of sending command status messages from
4119 server to client in server's command.c. The old way violated
4120 protocol specification.
4122 Changes to silccore/silccommand.[ch]: removed
4123 silc_command_encode_status_payload -> not needed anymore,
4124 changed silc_command_encode_payload_va to accept extra
4125 argument on variable argument list. The argument type must
4126 now be provided to the function. Also, added new function:
4127 silc_command_encode_reply_payload_va which is same as
4128 normal command_encode_payload_va except command status type
4129 is provided as extra argument.
4131 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Added ~./silc directory handling. The directory includes the
4134 public and private keys for the client.
4136 Added silc_client_check_silc_dir, silc_client_create_identifier
4137 and silc_client_load_keys.
4139 * Implemented SILC protocol compliant public key. Added public
4140 and private key saving to and loading from files.
4142 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4143 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4144 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4145 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4146 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4148 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4149 silc_pkcs_load_[public/private]_key.
4151 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Added silc_server_get_route (route.[ch]) to get connection
4154 data for the fastest route for given ID.
4156 * Implemented INVITE command on client and server. The command
4157 were re-defined in the SILC Protocol Specification and the
4158 implementation now complies with the specification.
4160 * Implemented PING command on client and server.
4162 * Implemented NAMES command on client and server. The server side
4163 supports currently only normal server not router server yet.
4164 Some changes to NAMES definition in SILC protocol specification.
4166 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Implemented LEAVE command on client and server.
4170 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4171 again. This change was made to the protocol as well. Server
4172 should not violate the protocol specification anymore.
4174 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4177 was tested. SOCKS4 was not but should work anyway.
