3 * Do not say "You have left channel %s" in client library.
4 Moved it to the application. Affected files are
5 lib/silcclient/command.c and silc/client_ops.c.
7 * Fixed silc_client_get_clients. Command context was not
8 duplicated and was freed memory in the callback. Affected
9 file lib/silcclient/idlist.c.
11 * Do not say "you are now talking..." on JOIN command in the
12 client library. The appliation must handle it.
14 * Do not say ".. changed topic to" in command reply in the
15 client libary. The application must handle it.
17 * Fixed TOPIC command sending in the client library.
19 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
21 * Imported a modified version of Irssi client to the source tree.
22 The Irssi will be used to create a new client called
23 Irssi SILC. Imported to irssi/.
25 Added silc_core_init_finish function to the Irssi. Affected
26 file irssi/configure.in.
28 A lot changes in the Makefile.ams around the irssi tree.
30 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
32 * Do not rehash if the new size is same as the old size of the
33 hash table, in the silc_hash_table_rehash*. The affected file
34 lib/silcutil/silchashtable.c.
36 * Replaced hash_table_del_by_context calls from the server
37 (when channel->user_list and client->channels) to the
38 hash_table_del as it is sufficient and faster.
40 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
42 * Added silc_hash_table_list, silc_hash_table_get and the
43 SilcHashTableList structure to provide an alternative way to
44 traverse the hash table. The affected files are
45 lib/silcutil/silchashtable.[ch].
47 * Changed the server's idlist routines to use the hash table
48 routines to optimize the code.
50 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
52 * Replaced the client entry's `channel' list and channel entry's
53 `user_list' list to hash tables for optimized lookup. Changed
54 the code to use the hash table interface around the code.
55 Affected file lib/silcd/idlist.[ch].
57 * Added `auto_rehash' boolean argument to the function
58 silc_hash_table_alloc to indicate whether the hash table should
59 auto-rehash when it thinks is appropriate time. It will
60 increase the hash table size if the there is twice as much
61 entries in the table than the size of the table, and will
62 decrease the size if there are twice as less entries than
63 the size of the table.
65 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
67 * Fixed silc_xxx_get_supported to not crash at some circumstances.
69 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
71 * silc_idcache_purge_by_context deletes the entry now by context
72 as it is supposed to do. Affected file lib/silccore/idcache.c.
74 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
75 client is not anymore valid (WHOWAS givens the info) and not
76 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
78 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
80 * Removed the `data' and `data_len' arguments from the ID Cache
81 interfaces and added `name' argument. ID Cache does not handle
82 anymore the binary data only a names associated with given ID.
84 * When hashing a Client ID with silc_hash_id the entire ID is
85 not hashed anymore, instead only the hash of the Client ID is
86 hashed. This way we can access the Client ID from the cache
87 with Client ID but with the hash of the ID (which is a hash of
88 the nickname) as well without any difference in performance.
90 Added also silc_idcache_find_by_id_one_ext to do one on one
91 searching when we have the actual ID. Added also function
92 silc_hash_client_id_compare. The affected files are
93 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
95 * When hashing the name associated with a ID it is always done
96 in lowercase. This way we can access the cache without worrying
97 about case-sensitivity, even though, for example nicknames are
100 * Fixed a bug in server with channel message sending. It put
101 wrong ID type as destination ID. The affected file
104 * silc_idcache_del_by_context now deletes from all hash tables
105 by context. Affected file lib/silccore/idcache.c.
107 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Changed the client library to use the new ID Cache interface.
110 Changes around the source tree.
112 * Added silc_hash_table_rehash_ext to rehash with specific
113 hash function. Affected file lib/silcutil/silchashtable.[ch].
115 * Added silc_hash_string_compare to compare two strings in the
116 hash table. Affected file lib/silcutil/silcutil.[ch].
118 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
120 * Added new function silc_idcache_del_by_context into the
121 lib/silccore/idcache.[ch].
123 * Changed the server's ID list routines to use the new ID Cache
124 interface. Changes around the source tree.
126 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
128 * Added silc_hash_table_del[_by_context]_ext functions in to the
129 lib/silcutil/silchashtable.[ch].
131 Removed silc_hash_table_find_all* routines and added new
132 silc_hash_table_find_foreach to replace them.
134 Added silc_hash_table_replace_ext function as extended
135 replacing function. Separated the simple hash table interface
136 from the extended hash table interface in the file
137 lib/silcutil/silchashtable.h.
139 * Fixed minor bugs and changed it to use some of the new
140 hash table functions in lib/silccore/idcache.c
142 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
144 * Added new function silc_hash_table_find_all to return all keys
145 in the hash table by the specified key. As the hash table is
146 collision resistant it also makes it possible to have several
147 duplicate keys in the hash table. This function may be used to
148 find all of the keys from the hash.
150 Added user_context arguments to the SilcHashFunction,
151 SilcHashCompare and SilcHashDestructor to deliver user specified
154 Added new fuctions silc_hash_table_find[_all]_ext to do
155 extended lookup with specified hash and compare functions and
156 specified user contexts.
158 Added new function silc_hash_table_add_ext to add the key
159 with specified hash function and user context.
161 Added new function silc_hash_table_foreach to traverse all
162 entrys in the hash table. Added SilcHashForeach callback
165 Added new function silc_hash_table_del_by_context to delete
166 the entry only if the context associated with the key matches.
168 Affected files are lib/silcutil/silchashtable.[ch].
170 * Removed silc_hash_[server/client/channel]_id and added just
171 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
172 silc_hash_id_compare to compare two ID's using as the hash table
173 comparison function. Added also silc_hash_data to hash
174 binary data and silc_hash_data_compare to compare it.
176 * Removed silc_idlist_find_client_by_hash as it is not needed
177 anymore. Affected file silcd/idlist.[ch].
179 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
180 to use internally the SilcHashTable. The new ID Cache is a lot
181 faster than the old one. Some of the ID Cache interface was also
182 rewritten and obsolete and stupid functions were removed.
184 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
186 * Added entry_count field to the SilcHashTable to keep the number
187 of the entries in the table. Implemented the function
188 silc_hash_table_rehash. Added new function
189 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
191 Fixed a minor bug in silc_hash_table_free.
193 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
194 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
195 into the lib/silcutil/silcutil.[ch].
197 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
199 * Implemented a collision resistant hash table into the
200 lib/silcutil/silchashtable[ch]. See the header and the source
201 for the SilcHashTable API.
203 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
205 * Merged dotconf version 1.0.2 into lib/dotconf.
207 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
209 * Do not compile anything in lib/silcsim/* if the SIM support
210 is not enabled. The tree should now compile without problems
213 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
215 * Compiled the SILC under cygwin. Compiled and tested briefly
216 without problems. More tests needed. The SIMs didn't compile
219 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
221 * Fixed possible crash in silc_get_username in the
222 lib/silcutil/silcutil.c.
224 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
226 * Fixed a va_arg in silc/client_ops.c.
228 * Oops, RC5 routines were named AES and caused some problems
229 when not using SIM's. Affected file lib/silccrypt/rc5.c.
231 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
233 * Added new SilcIDIP structure into the lib/silccore/id.h and
234 replaced the old `ip' fields from all SILC ID's to that type.
235 This is a step towards IPv6 support.
237 The silc_id_get_len takes now the ID as an extra argument.
238 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
239 both IPv4 and IPv6 based ID's.
241 The affected files are lib/silccore/id.[ch] and other files
242 around the tree using these routines.
244 * Removed the ID length arguments in server from various
245 silc_server_send_notify_* routines -> they are not needed
248 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
250 * Fixed memory leak in silc_encode_pem_file in the file
251 lib/silcutil/silcutil.c.
253 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
255 * Check minor version as well in the SKE. Affected files are
256 silcd/protocol.c and lib/silcclient/protocol.c.
258 * Added --identifier option to the server so that an identifier
259 can be when creating the public key for the server. Affected
260 file is silcd/silcd.c.
262 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
263 lib/silccrypt/silcpkcs.c.
265 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
267 * Register default ciphers and stuff when using -C option with
268 the server. Affected file sildc/silcd.c.
270 * Put back the servers public key filename format, it is better
271 than the new one. For now, the client keys are saved with the
272 new filename format. The affected file silc/client_ops.c.
274 * Implemented the Cipher API for the rest of the ciphers that
275 did not implement it or implemented it the wrong way.
277 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
279 * Register default ciphers and stuff when using the -S option
280 in the client. Affected file silc/silc.c. Same also when
281 creating new key pair with -C option.
283 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
285 * Fixed the silc_verify_public_key client operation function to
286 save the public keys differently. The fingerprint is now
287 used as filename and not the hostname. This way also the
288 client keys are saved uniquely and not with hostnames. The
289 affected file is silc/client_ops.c.
291 * Trimmed the silc_hash_fingerprint function to remove extra
292 whitespaces from the end of the fingerprint. The affected
293 file is lib/silccrypt/silchash.c.
297 * Added silc_cipher_register_default function to register all
298 default ciphers. It can be used when configuration files
299 does not exist and the application does not want any specific
300 ciphers in any specific order.
302 The SilcDList is now used as silc_cipher_list dynamically
303 allocated cipher list. Removed the static list all together
304 and now all ciphers must be allocated to the dynamic list.
305 The silc_cipher_alloc routine was changed to check only the
308 All silc_cipher_* routines that used to return int returns
311 The affected files lib/silccrypt/silccrypt.[ch].
313 * The same thing was done to silc_hash_* as for silc_cipher_*
314 routines. Affected files lib/silccrypt/silchash.[ch].
316 * The same thing was done to silc_pkcs_* as for silc_cipher_*
317 routines. Affected files lib/silccrypt/silcpkcs.[ch].
318 Added also silc_pkcs_[un]register[_default] functions.
319 Removed the data_context from the PKCS API.
321 * Added silc_hmac_register_default function to register default
322 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
323 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
324 to unregister all hmacs at once.
326 * Register the default ciphers, hash functions, PKCSs and HMACs
327 if client's configuration file does not exist. The affected
330 * The client did not load the hash functions from the SIM
331 modules at all. Added support for this. Affected file is
334 * When decoding public key with silc_pkcs_public_key_decode, check
335 the supported algorithm only if PKCS are registered. Affected
336 file lib/silccrypt/silcpkcs.c. The same was done with the
337 silc_pkcs_private_key_decode.
339 * Fixed the SILC List routines to keep the list always in order.
340 It used to change the list's order when traversing the list but
341 not it preserves the order. Affected file lib/trq/silclist.h.
343 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
345 * Added the client library to use the SilcSocketConnection's
346 reference counter (by silc_socket_dup) to prevent the bug that
347 the socket object may be freed underneath async operation.
349 * The name resolv library checking fixes in the configure.in.pre.
352 * Created new version of the protocol drafts for future
353 development. The -03 drafts are the ones that will be changed
354 in the trunk now and the -02 will remain as they are.
356 * Send list of CUMODE notifys to the router when announcing
357 the channel users to the router. Affected file silcd/server.c.
358 If the router receiving channel founder CUMODE for a channel
359 that already has channel founder it will send CUMODE notify
360 to the sender to remove the channel founder rights from the
361 announced client. Affected file silcd/packet_receive.c.
363 * The CUMODE notify may now use Server ID as well as the entity
364 who changes the mode. Updated protocool specs.
366 * Updated INSTALL and README files.
368 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
370 * New web pages in the http://silc.pspt.fi. The pages was
375 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
377 * Implemented the [DenyConnectin] config section in the server.
378 Added silc_server_config_denied_conn to check whether incoming
379 connection is denied. Affected file silcd/serverconfig.[ch].
381 * Do not check the ports when checking the incoming configuration
382 data if the port is 0, meaning any. Affected file is
383 silcd/serverconfig.c.
385 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
387 * Fixed buffer overflow in silc_string_compare in the file
388 lib/silcutil/silcutil.c.
390 * Fixed double free in silc_server_command_leave in the file
393 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
395 * Fixed the version checking in the server. Affected file is
398 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
400 * Fixed the configuration data fetching when accepting new
401 connections in the server. Affected file silcd/server.c.
403 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
405 * Added `sender_entry' argument to the function
406 silc_server_packet_relay_to_channel so that we can check
407 whether some destination actually belongs to the same route
408 the sender belongs (ie, we must not resend the packet to the
409 sender). Affected file silcd/packet_send.[ch].
411 * Added `servername' field to the SilcClientEntry in the server
412 to hold the name of the server where client is from. Affected
413 file is silcd/idlist.h.
415 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
417 * Moved the channel message encrypting in the router betwen
418 router connections from silc_server_channel_message to the
419 silc_server_packet_relay_to_channel since we want to check
420 whether we have anybody channel before encrypting anything.
421 Affected files silcd/packet_[receive/send].c.
423 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
425 * Fixed the [AdminConnection] server config section to support
426 multiple entries. Affected file silcd/serverconfig.c.
428 * Added support into the server to check the validity of the
429 incoming connection before executing any KE or authentication
432 * The connection configuration is now saved to the KE and
433 connection auth protocol contexts and not fetched anymore in
434 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
436 * The local hosts listenning address and port is also resolved
437 now when starting the server. We want to have the socket object
438 to include the real address and port for the listener. Added
439 new function silc_net_check_local_by_sock into the files
440 lib/silcutil/silcnet.[ch].
442 * Fixed a broadcast bug in server -> do not broadcast if we
445 * Fixed a routing bug. Do not route broadcast packets ever.
446 Broadcast packets must be processed always and not routed since
447 they may be destined to some other host than yourself and thus
448 would get routed without no good reason. Affected file is
451 * Added function silc_server_config_is_primary_route to check
452 whether primary router connection has been configured (a router
453 configuration that we are initiating). If there is not, we
454 will assume that there is only two routers in the SILC network
455 and we will use the incoming router connection as our primary
456 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
458 * Changed the order of the broadcasting. Broadcast _after_ the
459 packet has been processed not before. Affected file is
462 * Fixed a [ClientConnection] parsing bug. The port was never
463 parsed correctly thus resulting to port 0. Affected file
464 silcd/serverconfig.c.
466 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
467 argument and did not set the broadcast packet flag. Affected
468 file silcd/packet_send.c. Fixed same bug in the function
469 silc_server_send_notify as well.
471 * If we receive NEW_ID packet for our own ID in the server, ignore
474 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
478 * Removed the nickname from the Private Message Payload.
479 Updated the code and the protocol specs.
481 * Updated protocol specs for submitting to the IETF.
483 * Tweaked the Random Number Generator a bit. Affected file
484 lib/silccrypt/silcrng.c. Exported a new function
485 silc_rng_[global]_add_noise which can be used to add more
488 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
490 * Do not parse packets with different timeout when protocol
491 is active -> may cause problem with rekey. Affected file
494 * When server receives signoff notify it must not create
495 new channel key if the client is on any channels since the
496 sender of the signoff notify will create it.
498 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
500 * Added printing of error messages during SKE protocol from the
501 failure packet sent by server during SKE. Affected file
504 * Removed the client's failure_callback handling with timeout
505 and handle it immediately when received.
507 * The SKE library returned wrong type in SUCCESS and FAILURE
508 packets. They must be 32 bit MSB not 16 bit MSB.
510 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
512 * Ok, rewrote the logic of the re-key and now it seems to work.
513 I tested it on high traffic with frequent re-keys without
514 problems. Added hmac_receive (and renamed hmac to hmac_send)
515 in SilcClientConnection in lib/silcclient/client.h and
516 in SilcIDListData in silcd/idlist.h. Also, removed the
517 SilcPacketParserContext's cipher and hmac fields as they are
518 not needed anymore and actually caused some problems when
519 the ciphers and hmac's changed underneath the packet parser.
521 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
523 * If re-key protocol is active then process the incoming packets
524 synchronously since we must assure that icoming packets encrypted
525 with the old key is processed before the new keys is set to
526 use. This is true other packets than for REKEY packets.
527 Affected file silcd/server.c. The same was done to client library
528 as well, affected file lib/silcclient/client.c.
530 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Fixed bug in client and server to accept the force send if
533 the packet is send from silc_[server/client]_packet_process
534 function. Otherwise the packets are never delivered, oops.
536 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
538 * Disable force sending of packets when REKEY protocol is active.
539 We must assure that no packet is sent directly when rekey is
540 performed. All packets must be sent through packet queue.
541 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
542 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
543 function is silc_[server/client]_packet_send_real to check
546 * Replaced the SIM paths from example config files to
547 /usr/local/modules. Also, make install creates now
548 /usr/local/silc/logs directory to hold all the SILC server
551 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
553 * Made the configure.in.pre work on Solaris. Patch by salo.
555 * Made all ciphers compatible with non-x86 machines. Defined
556 CBC mode macros into lib/silccrypt/ciphers_def.h.
558 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
560 * Fixed the make install.
562 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
564 * When MAC computation fails the silc_packet_decrypt returned 0
565 even though it was supposed to return -1. Fixed this. The
566 affected file is lib/silccore/silcpacket.c.
568 * Do not replace the config files in /etc/silc (in make install)
569 if they already exist. Affected file ./Makefile.am.
571 * Do not send re-key packets immediately but through packet queue.
572 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
574 * Changed silc_net_check_host_by_sock to return FALSE if the
575 IP/DNS could not be resolved. Though, it returns the IP address
576 now even if it could not resolve it (but returns also FALSE).
577 Affected file lib/silcutil/silcnet.[ch].
579 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
581 * Added silc_pkcs_decode_identifier to decode the public key's
582 identifier. Affected file lib/silccrypt/silpkcs.[ch].
583 Added also silc_pkcs_free_identifier. Added also new context
584 SilcPublicKeyIdentifier.
586 * Added -S option to the silc client. It is used to dump the
587 contents of the specified public key file.
589 * Changed the PKCS api to return the public key length when
590 setting the public key.
592 * Fixed a fatal bug in the public and private key file loading.
593 Affected file lib/silccrypt/silcpkcs.c.
595 * Execute the packet parsing for client with zero (0) timeout
596 if the protocol is active. Affected file silcd/server.c.
598 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
600 * Made the key generation options to the silcd program. Added
601 -C option, equivalent to client's option.
603 * Added new [ServerKeys] config section to the server. It
604 configures the server's public and private key.
606 * Defined generic Public Key Payload into the protocol
607 specification to send specific type of public keys and
610 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
611 public key or certificate.
613 * Implemented the GETKEY command to the server and to the
614 client library and on user interface.
616 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * Made preliminary `make install' work.
620 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
622 * Added SilcServerRekey context into silcd/idlist.h.
624 * Added the PFS support as defined in the specification to the
625 SKE protocol. Affected files lib/silcske/*.c.
627 * Added `ske_group' field to the SilcServerRekey context to hold
628 the number of the SKE group that is used with PFS in re-key.
629 Affected file silcd/idlist.h.
631 * Added PFS re-key support to the server. Affected file is
634 * Added silc_protocol_cancel to cancel execution of the next
635 state of the protocol. Affected file is
636 lib/silccore/silcprotocol.[ch].
638 * Added the re-key support with and without PFS to the client
639 library. Re-key is performed once in an hour, by default.
641 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
642 Added silc_client_rekey_callback and silc_client_rekey_final.
643 Affected files are lib/silcclient/protocol.[ch] and
644 lib/silcclient/client.[ch].
646 * Removed the `hmac_key' and `hmac_key_len' fields from the
647 SilcClientConnection structure; not needed. Affected file is
648 lib/silcclient/client.h.
652 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
654 * Do not ask whether user wants to use the negotiated private key
655 for private messages, just use it. Affected file is
656 silc/local_command.c.
658 * Added `send_enc_key' and `enc_key_len' fields to the
659 SilcIDListData structure since they are needed in the re-key
660 phase. Affected file is silcd/idlist.[ch].
662 * Implemented the simple re-key protocol into the server.
663 Affected files silcd/server.c and silcd/protocol.[ch]. The
664 re-key will be performed once in an hour, by default.
666 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
667 Added silc_server_rekey, silc_server_rekey_callback and
668 silc_server_rekey_final.
670 * Removed Tunneled flag from the protocol. Updated the code
671 and the specifications.
673 * Adde `pfs' field to the SilcIDListData to indicate whether
674 the PFS is to be performed in the re-key. Affected file is
677 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
680 int64 of at least the xintXX size. If void * is less that 4
681 bytes uint32 * will be used. Defined bool as boolean.
683 * Changed _ALL_ unsigned long and unsigned int to uint32,
684 unsgined short to uint16 in the source tree.
686 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
687 not handle clients that has entry->data.registered == FALSE.
688 They are not in the network anymore. Affected file is
691 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
693 * Implemented the sending of the SERVER_SIGNOFF notify in the
694 server. Affected file is silcd/server.c.
696 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
697 Added also silc_notify_payload_encode_args into the
698 lib/silccore/silcnotify.[ch].
700 * Implemented ther SERVER_SIGNOFF notify handling in the server.
701 Affected file silcd/packet_receive.c.
703 * Implemented the SERVER_SIGNOFF notify handling in the client
704 library. Affected file lib/silcclient/client_notify.c. Also,
705 implemnted the printing of the SERVER_SIGNOFF info to the
706 application. Affected file silc/client_ops.c.
708 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
709 if the deleting was successful. Affected file silcd/idlist.[ch].
711 * Added support for public key authentication in the connection
712 authentication protocol in the client library. Affected file
713 lib/silcclient/protocol.c.
715 * Changed the server's silc_idlist_get_clients_by_* interface
716 to support already allocated array so that new entries may be
717 added to pre-allocated array. Affected file silcd/idlist.[ch].
718 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
721 * All command reply functions in the server now calls the
722 pending command callback even if error occured. This way the
723 error will be delivered to the client as well. Affected files
724 silcd/command.c and silcd/command_reply.c.
726 * Fixed INFO command to return local server's info if no server
727 was provided. Affected file lib/silcclient/command.c.
729 * Removed RESTART command for good. Updated the code and the
732 * Rewrote parts of the task system. It is a bit simpler now.
733 Removed unsued task priorities. The affected files are
734 lib/silcutil/silctask.[ch].
736 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
738 * Moved the USERS printing from the library to the application.
739 Affected files lib/silcclient/command.c and silc/client_ops.c.
741 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
745 * Added channel key re-key support. The re-key is perfomed
746 only by the router and is done once in an hour. Added `rekey'
747 field to the SilcChannelEntry in the server. Affected files
748 silcd/server.c and silcd/idlist.h.
750 * Added silc_task_unregister_by_context into the file
751 lib/silcutil/silctask.[ch].
753 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * Added SILC_UMODE_GONE mode to indicate when the client is not
756 present in the SILC network. Added also support to the local
757 command AWAY that will set this mode. Added support of showing
758 "xxx is gone" in WHOIS command. The USERS command shows the
761 * Fixed setting server and router operator privileges in the
762 server's UMODE command. Affected file silcd/command.c.
764 * Merged the SKE KE1 and KE2 payloads into one payload. The
765 new KE payload is equivalent to the old KE2 payload.
767 Cleaned up the SKE Start Payload parsing. It now uses the
768 simple buffer unformatting to do the parsing. A lot faster
771 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
772 to the SKE that is used to indicate whether both of the SKE
773 parties should perform authentication. By default only the
774 responder performs authentication. By setting this flag also
775 the initiator must do authentication. By default it is unset
776 since in normal SKE case, client to server connection, only
777 the responder should do authentication. When doing SKE between
778 two clients both should perform authentication. Updated the
779 code and the protocol specs.
781 * A little fix to IDENTIFY command in the server. Search the
782 client first by hash not nickname. Affected file is
785 * Fixed the silc_client_close_connection to support closing
786 the client to client connections wihtout deleting too much
787 data. Affected file lib/silcclient/client.c.
789 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
790 are received if protocol used to be active but is not anymore
791 the application would crash due to NULL pointer dereference.
792 Affected files silcd/server.c and lib/silcclient/client.c.
794 * Added `hash' field to the SilcClientConnection to include
795 the hash function negotiated in the SKE protocol.
797 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
798 to set the channel founder authentication data. A client can
799 claim the founder rights later by providing the authentication
800 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
801 This way the channel founder can regain the channel founder
802 privileges even it is left the channel. This works only on
803 local server and the client must be connected to the same
804 server to be able to regain the founder rights. Updated the
805 protocol specs accordingly.
807 Added support to the CMODE command in the client to set the
808 founder auth data. Read the README to see how to set it.
810 Added support to the CUMODE command to claim the founder
811 rights. Read the README to see how to do it.
813 Added support for the founder authentication to the Channel
814 Entry in the server. Affected file silcd/idlist.h.
816 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
817 server's CMODE command. Affected file silcd/command.c.
819 * Added the following new functions into lib/silccore/silcauth.[ch]:
820 silc_auth_get_method and silc_auth_get_data.
822 * The server now saves the remote hosts public key to the
823 SilcIDListData pointer. Affected file silcd/protocol.c.
825 * The normal server now does not remove the channel entry from
826 the cache if the founder authentication data is set. It used
827 to remove it if the founder was the last one on the channel on
828 the server and left the channel. The auth data is saved and
829 if the channel is re-joined later the old entry is used with
830 the old auth data. Affected files silcd/command_reply.c and
833 * Removed the `pkcs' field from the SilcIDListData structure
834 in the server; it is not used. Affected file silcd/idlist.h.
836 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
838 * Fixed packet processing on slow links. Partial packets were
839 never re-processed because the incoming data buffer was cleared
840 by the application. Application must not directly clear the
841 sock->inbuf, the packet processing routines handle it. Fixed
842 this in client library and in server.
844 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
846 * Fixed the WHOIS and IDENTIFY send reply function to really
847 check whether to send list or just one entry. Affected file
850 * Cleaned up the LEAVE command's channel key distribution. The
851 affected file silcd/command.c.
853 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
854 can enforce the channel mode as well. In that case the ID
855 includes the ID of the server. The code now enforces the
856 mode change if the router have different mode than the server.
858 * The notify client operation with CMODE_CHANGE notify can now
859 return NULL client_entry pointer if the CMODE was not changed
860 by client. Application must check for this.
862 * Added <Server ID> argument to INFO command to support server
863 info fetching by Server ID.
865 * Added silc_server_announce_get_channel_users to get assembled
866 packets of channel users of the specified channel. Affected
867 file silcd/server.[ch].
869 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
870 was freed underneath the ID Cache.
872 * Re-announce clients when the server received CHANNEL_CHANGE
873 notify from the router. Affected file silcd/packet_send.c.
875 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
877 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
878 crashed since it did not handle the fact that there is no cipher
879 called "3" and didn't check the error condition. Now fixed.
881 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
882 flag. It can be used to send message requests.
884 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * Implemented the RESTART command in the client.
888 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
889 notice type messages. Added notice printing to the user
892 * The channel keys are not re-generated if the channel's mode
893 is PRIVKEY, ie private key on the channel exists. Affected
894 files silcd/server.c and silcd/command.c.
896 * Fixed a little bug in channel message delivery when channel
897 private keys are set in the server. Affected file is
900 * Changed the setting on channel->on_channel = TRUE from the
901 silc_client_save_channel_key to the JOIN command reply. The
902 key payload is not received if the private channel key is set.
903 Affected file lib/silcclient/command_reply.c and the
904 lib/silcclient/client_channel.c.
906 * When the CMODE_CHANGE notify is sent and the channel private
907 key mode is removed the channel key must be re-generated in
908 other cells as well. Added this support for the router in the
909 silcd/packet_receive.c.
911 * Added new local command NOTICE to send notice message on
912 channel. Affected file silc/local_command.[ch].
914 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Added new local command ME to the client. It is used to send
917 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
918 some action. Affected file silc/local_command.[ch].
920 * Changed channel_message and private_message client operations
921 to deliver the message flags to the application. Added also
922 the `flags' arguments to the silc_client_send_channel_message
923 and silc_client_send_private_message functions. Affected file
926 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
928 * Redefined the Private Message Payload to support private message
929 keys and to support the new private message flags. Updated
930 the protocol specs. Flags makes it possible to have for example
933 * Added new type SilcPrivateMessagePayload and defined an API
934 for it in the lib/silcclient/silcprivate.[ch].
936 * Tested private message private keys successfully. Tested the
937 private message key set, unset and list commands with the new
940 * Redefined the Channel Message Payload to include the channel
941 message flags (equal with private message flags) to support
942 for example CTCP style messages.
944 * Defined some of the message (for channel and private message)
945 flags. Updated the protocol specs and added the flags to the
946 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
948 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
950 * Added SilcKeyAgreementStatus type to the key agreement routines
951 to indicate the current status and error if one occured.
952 The status types are defined in the lib/silcclient/silcapi.h.
954 * Added new local command KEY that is used to set and unset private
955 keys for channels, set and unset private keys for private messages
956 with remote clients and to send key agreement requests and
957 negotiate the key agreement protocol with remote client. The
958 key agreement is supported only to negotiate private message keys,
959 it currently cannot be used to negotiate private keys for channels,
960 as it is not convenient for that purpose.
962 * Fixed a minor pending callback setting bug in the function
963 silc_client_get_client_by_id_resolve, now the function works.
964 Affected file lib/silcclient/idlist.c.
966 * Added function silc_net_get_local_port to get local bound
967 port by socket. Added to lib/silcutil/silcnet.[ch].
969 * Added `sockets' and `sockets_count' fields to the SilcClient
970 object. They hold the sockets of the listenning sockets in
971 the client. Listenning sockets may be for example the key
972 agreement server. Affected file lib/silcclient/client.[ch].
973 Added functions the silc_client_add_socket and the
974 silc_client_del_socket. They are exported to the application
977 * Added ~./silc/clientkeys to support other client's public keys.
979 * Renamed verify_server_key client operation to verify_public_key
980 and added one argument to indicate the type of the connection
981 (server, client etc.).
983 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
985 * Added silc_server_connection_auth_request to handle the
986 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
987 silcd/packet_receive.[ch].
989 * Added silc_server_send_connection_auth_request into the
990 silcd/packet_send.c to send the connection auth request packet.
992 * Cleaned up the silcd/protocol.c a bit and fixed some memory
995 * Fixed the public key authentication in responder side in the
996 server. The `auth_data' pointer includes the SilcPublicKey
997 not the path to the public key. Affected file silcd/protocol.c.
999 * Implemented the public key authentication in the initiator side
1000 in the server. Affected file silcd/protocol.c.
1002 * Removed the [RedirectClient] config section from the server
1003 configuration. Is not needed and I don't want to implement it.
1005 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1007 * Cleaned up the CMODE command in the server. It now works
1008 correctly and supports all the modes defined in the protocol.
1009 Affected file is silcd/command.c.
1011 * Added `hmac_name' field to the SilcChannelEntry in the server
1012 to hold the default HMAC of the channel. It can be set when
1013 creating the channel (with JOIN command). Affected files
1016 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1017 type to indicate the change of the current cipher and hmac
1018 on the channel. Client can safely ignore the <cipher> argument
1019 (if it chooses to do so) since the CHANNEL_KEY packet will
1020 force the channel key change anyway. The <hmac> argument is
1021 important since the client is responsible of setting the new
1022 HMAC and the hmac key into use.
1024 * Fixed the CMODE command in the client library as well.
1026 * Tested CMODE command in router environment successfully.
1028 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1030 * Show the version of the remote client (or server) when connecting
1031 to the server. It is logged to the log file. Affected file
1032 is silcd/protocol.c.
1034 * Fixed the KILLED notify handling in the client library. The
1035 client must be removed from all channels when receiving the
1038 Also, do not remove the client entry when giving the KILL
1039 command but when the KILLED notify is received.
1041 * Removed silc_idlist_find_client_by_nickname from the server.
1042 Not needed anymore. Affected files silcd/idlist.[ch].
1044 * Implemented the CHANNEL_CHANGE notify type handling to the
1045 server. Affected file silcd/server.c.
1049 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1051 * Added silc_server_send_notify_invite to send the INVITE
1052 notify between routers.
1054 * Implemented the INVITE command correctly to the server.
1056 * Implemented the INVITE notify type handling in the server.
1058 * Implemented the INVITE command to the client library and on the
1061 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1063 * Added function silc_server_get_client_resolve to find the
1064 client entry by ID from all ID lists and then resolve it
1065 (using WHOIS) if it cannot be found. Affected file is
1068 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1070 * Implemented the BAN command to the client library.
1072 * The JOIN command in the server now checks the invite list
1075 * Changed the silc_command_reply_payload_encode_va and the
1076 silc_command_payload_encode_va to support that if argument is
1077 NULL it ignores and checks the next argument. Affected file
1078 lib/silccore/silccommand.c.
1080 * Added silc_server_send_notify_ban to send the BAN notify
1081 type between routers.
1083 * Chaned the silc_notify_payload_encode to support that if
1084 argument is NULL it ignores and checks the next argument.
1085 Affected file lib/silccore/silcnotify.c.
1087 * Tested ban lists in router environment successfully.
1089 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1091 * Implemented BAN command to the server, in silcd/command.[ch].
1093 * Removed the BAN and INVITE_LIST modes from the CMODE command
1096 * Added function silc_string_match to regex match two strings.
1097 Affected files lib/silcutil/silcutil.[ch].
1099 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * Redefined parts of the SilcChannelEntry in the server to support
1102 the new ban and invite lists.
1104 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1106 * Redefined the INVITE command. The same command can be used to
1107 invite individuals to the channel but also to manage the invite
1108 list of the channel (to add to and remove from the invite list).
1109 Updated the protocol specs.
1111 * Added new command SILC_COMMAND_BAN that can be used to manage
1112 the ban list of the channel. Updated the protocol specs.
1114 * Removed the channel modes: the SILC_CMODE_BAN and the
1115 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1116 in the CMODE command. The equivalent features are now available
1117 using INVITE and BAN commands. Updated the protocol specs.
1119 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1120 in the network about change in the current ban list. The notify
1121 type is not used by the client.
1123 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1124 support the invite lists.
1126 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1128 * Added new function silc_string_regexify that converts string
1129 including wildcard characters into regex string that can
1130 be used by the GNU regex library. Added into the file
1131 lib/silcutil/silcutil.[ch].
1133 Added silc_string_regex_combine to combine to regex strings
1134 into one so that they can be used as one regex string by
1135 the GNU regex library. Added into the file
1136 lib/silcutil/silcutil.[ch].
1138 Added silc_string_regex_match to match two strings. It returns
1139 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1141 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Imported GNU regex to the soruce tree into lib/contrib.
1144 Fixed some compiler warning from the regex.c.
1146 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1148 * Fixed MOTD command in the server to work in router environment.
1150 * Fixed the MOTD command in the client library to support
1151 the server argument in the command.
1153 * Added `nickname_len' argument to the silc_idlist_add_client
1154 in the server, as the `nickname' argument may be binary data
1157 * Added silc_idlist_get_channels to return all channels from
1160 * Implemented LIST command to the server. Affected file is
1163 * Implemented the LIST command to the client library and on the
1166 * Added [<user count>] argument to the LIST command reply.
1167 With private channels the user count is not shown.
1169 * Updated TODO and README.
1171 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1173 * The client entry's data.registered must be TRUE even with
1174 global client entry on global client list. The data.registered
1175 is used to check whether the client is anymore in the network,
1176 for example with WHOWAS command so it must be valid.
1178 * Fixed the WHOWAS command in the server. It now actually works
1179 in router environment. Added function into silcd/command_reply.c
1180 silc_server_command_reply_whowas_save.
1182 * Added silc_idlist_purge function to the silcd/idlist.c
1183 to periodically purge the ID Cache.
1185 * Fixed INFO command in the server. It works now in router
1186 environment. Added <server name> argument to the INFO command
1187 reply. Updated the protocol specs.
1189 * Fixed minor bug in silc_idcache_purge to not purge if the
1190 expire value is zero.
1192 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1193 they were buggy because of the WHOWAS information.
1195 * Fixed local command MSG to handle the async resolving of
1196 the remote client properly. It used to fail the first MSG.
1197 Affected file silc/local_command.c.
1199 * Added `data_len' field to SilcIDCache context.
1201 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1203 * Update TODO. Todo in commands in the server.
1205 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1208 used by routers as broadcast packet to inform other routers
1209 about the changed user mode.
1211 Implemented the notify handling in the server. Affected file is
1212 silcd/packet_receive.c. Added the function
1213 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1215 * Added new generic Channel Payload and deprecated the New Channel
1216 Payload. The New Channel Payload is now the generic Channel
1219 * Added new argument `mode' to the silc_server_send_new_channel
1220 as it is required in the Channel Payload now.
1222 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1223 and created a new and real SilChannelPayload to represent the
1224 new generic Channel Payload. Implemented the encode/decode
1225 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1227 * Added silc_server_get_client_channel_list to return the list
1228 of channels the client has joined for WHOIS command reply.
1229 Affected file silcd/server.[ch].
1231 * Implemented the channel list sending in the WHOIS command reply
1232 in server and in the client.
1234 Implemented the channel list displaying on the user interface
1235 as well. Affected file silc/client_ops.c.
1237 * Added silc_channel_payload_parse_list to parse list of Channel
1238 Payloads. It returns SilcDList list of SilcChannelPayloads.
1239 Client for example can use this function to parse the list of
1240 channels it receives in the WHOIS command reply. The caller
1241 must free the list by calling silc_channel_payload_list_free.
1242 Affected files lib/silccore/silcchannel.[ch].
1244 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1246 * Added one new argument <user mode> to the WHOIS command reply
1247 to return the mode of the user in SILC. Updated the protocol
1250 Implemented it to the server and client.
1252 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * Fixed the mode printing on the user interface on joining.
1255 Affected file silc/client_ops.c.
1257 * Implemented the UMODE command and user modes in general to the
1258 client library and to the user interface.
1260 * Implemented the UMODE command to the server.
1262 * The server now sends UNKNOWN_COMMAND error status if client sends
1263 unknown command. Affected file silcd/command.c.
1265 * All server commands now handle the command identifier the right
1266 way when sending the command reply to the client. The client can
1267 use to identify the command replies with the identifier.
1269 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Added silc_server_get_client_route to resolve the route to
1272 the client indicated by the client ID. Affected file is
1275 * Added silc_server_relay_packet as general function to relay
1276 packet to arbitrary destination. This deprecates functions
1277 like _send_private_message_key, _relay_notify etc. Affected
1278 file is silcd/packet_send.[ch].
1280 Removed silc_server_send_key_agreement,
1281 silc_server_send_private_message_key and
1282 silc_server_packet_relay_notify functions from the file
1283 silcd/packet_send.[ch].
1287 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1288 server. Affected file silcd/packet_receive.[ch].
1290 * Implemented the KILL command to the client. Implemented the
1291 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1292 Affected files lib/silcclient/command[_reply].c and
1293 lib/silcclient/client_notify.c. Implemented the KILL notify
1294 printing in the user inteface.
1296 * Fixed a lot silc_parse_nick memory leaks from the client
1297 library in the file lib/silcclient/command.c.
1299 * Changed the silc_server_send_notify_on_channels's `sender'
1300 argument from SilcSocketConnection to SilcClientEntry to
1301 check the sender as entry and not as connection object and not
1302 to send to the client provided as argument. The affected file
1303 is silcd/packet_send.[ch].
1305 * The notify packets that are destined directly to the client used
1306 to not to be processed by the server. Now changed that and the
1307 server processes all notify packets. After relaying the packet
1308 to the client the notify packet is processed in the server.
1310 * The silc_server_free_client_data now checks whether there is
1311 pending outgoing traffic for the client and purges the data to
1312 the network before removing the client entry.
1314 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1316 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1317 an client is killed from the SILC Network. Updated the protocol
1320 Added new function silc_server_send_notify_killed to the
1321 silcd/packet_send.[ch].
1323 * Added function silc_server_packet_relay_notify to relay notify
1324 packets that are destined directly to a client. In this case
1325 the server does not process the notify packets but merely relays
1326 it to the client. Affected file silcd/packet_send.[ch].
1328 Added also silc_server_packet_process_relay_notify to check
1329 whereto relay the notify. Affected file is
1330 silcd/packet_receive.[ch].
1332 * Implemented the KILL command to the server.
1336 * Added the backup schema desgined last fall to the protocol
1337 specs for everyone to see. The specification is in the
1338 *-spec-xx.txt draft and the packet type definitions for the
1339 backup routers is in *-pp-xx.txt draft. Thusly, added also
1340 new packet type SILC_PACKET_CELL_ROUTERS.
1342 * A big security problem in the implementation discovered. The
1343 signoff of an client did not cause new channel key generation
1344 which it of course should've done. The channel keys must be
1345 always re-generated when client leaves (or signoffs) the channel.
1346 The silc_server_remove_from_channels funtion now handles
1347 the channel key re-generation.
1349 * Added `sender' argument to the silc_server_send_notify_on_channels
1350 to not to send the client provided as argument. Affected file
1351 silcd/packet_send.[ch].
1353 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1355 * Implemented OPER and SILCOPER commands into the server and
1358 * Added silc_auth_verify and silc_auth_verify_data to verify
1359 the authentication directly from the authentication payload.
1360 It supports verifying both passphrase and public key based
1361 authentication. Affected file lib/silccore/silcauth.[ch].
1363 * Added `hash' field to the SilcIDListData structure. It is the
1364 hash negotiated in the SKE protocol. Affected file is
1367 * Slight redesigning of the SilcAuthPayload handling routines.
1368 Do not send SilcPKCS but SilcPublicKey as argument.
1370 * Implemented the public key authentication support to the
1371 serverconfig. The public key is loaded from the provided path
1372 and saved as authentication data to void * pointer. Thus,
1373 changed the unsigned char *auth_data to void *auth_data;
1375 * Fixed SHUTDOWN command to send the reply before the server
1376 is shutdown. :) Affected file silcd/command.c.
1378 * Fixed fatal bug in CONNECT command. The hostname was invalid
1379 memory and server crashed. Affected file silcd/command.c.
1381 * Fixed fatal bug in CLOSE command. The server_entry became
1382 invalid but was referenced later in the command. Affected file
1385 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1387 * Fixed fatal bug in failure packet handling. Server ignored
1388 the failure and thus crashed when it came.
1392 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1394 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1395 that the command may be executed only once in (about) 2 seconds.
1396 The old SILC_CF_LAG flag is same but allows command bursts up
1397 to five before limiting.
1399 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1400 server code. Various commands now includes the CF_LAG_STRICT
1401 flag to disallow any kind of miss-use of the command.
1403 * Fixed the silc_buffer_unformat to not to allocate any data
1404 if the length of the data is zero. It used to allocate the
1405 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1407 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1409 * Changed the format of AdminConnection configuration section
1410 in the server. Added username of the admin to the format.
1411 Affected files silcd/serverconfig.[ch].
1413 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1414 to return admin configuration data by host, username and/or
1417 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1419 * Implemented WHOWAS command to the server. Added the functions:
1421 silc_server_command_whowas_parse,
1422 silc_server_command_whowas_send_reply,
1423 silc_server_command_whowas_from_client and
1424 silc_server_command_whowas_from_server
1426 * Added <Client ID> argument to the WHOWAS command reply. Updated
1427 the protocol specs accordingly.
1429 * Implemented WHOWAS command and command_reply to the client
1432 Implemented the WHOWAS printing on the user interface.
1434 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1436 * Added new argument to the WHOWAS command reply, the real name.
1437 It is an optional argument. Updated the protocol specs.
1439 * Added SilcIDCacheDestructor callback that is registered when
1440 the SilcIDCache is allocated. The callback is called when
1441 an cache entry in the ID Cache expires, or is purged from the
1442 cache. Added into lib/silccore/idcache.[ch].
1444 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1445 to destruct the client entries when the cache entry expires.
1446 Other ID Cache's in server and in the client library ignores
1449 * If the ID Cache entry's `expire' field is zero then the entry
1450 never expires. Added boolean `expire' argument to the
1451 silc_idcache_add function in the lib/silccore/idcache.[ch].
1452 If it is TRUE the default expiry value is used.
1454 * Added silc_server_free_client_data_timeout that is registered
1455 when client disconnects. By default for 5 minutes we preserve
1456 the client entry for history - for WHOWAS command.
1458 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1460 * Added support to the server to enforce that commands are not
1461 executed more than once in 2 seconds. If server receives
1462 commands from client more frequently, timeout is registered
1463 to process the commands. Affected file silcd/command.c.
1464 Added new function silc_server_command_process_timeout.
1466 * Changed NICK_NOTIFY handling in client library to check that
1467 if the client's nickname was changed, so there is no need to
1468 resolve anything from the server.
1470 * Removed error printing from the WHOIS and IDENTIFY commands.
1471 If error occurs then it is ignored silently in the client library.
1472 The application, however, may map the received error to
1473 human readable error string. The application currently maps
1474 the NO_SUCH_NICKNAME error to string.
1476 * Made the command status message public to the application. Moved
1477 them from lib/silcclient/command_reply.c to
1478 lib/silcclient/command_reply.h. The application can map the
1479 received command status to the string with the
1480 silc_client_command_status_message function.
1482 * Added check to the server to check that client's ID is same
1483 as the Source ID in the packet the client sent. They must
1486 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Added dist-bzip hook to the Makefile.am to make bzip2
1489 compressed distributions.
1491 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1493 * Server now enforces the maximum length for the nickname and
1494 the channel as protocol specification dictates. 128 bytes for
1495 nickname and 256 bytes for channel name.
1497 * Moved the WHOIS printing to the application. The client libary
1498 does not print out the WHOIS information anymore, the application
1499 must do it. Renamed silc_client_command_reply_whois_print to
1500 the silc_client_command_reply_whois_save.
1502 The client's idle time is also sent to the application now, and
1503 the idle is shown on screen.
1505 * Added silc_client_command_reply_identify_save to save the
1506 received IDENTIFY entries.
1508 * Do not check for channel private keys in message sending and
1509 reception if the channel does not have the PRIVKEY mode set.
1510 Affected file lib/silclient/client_channel.c.
1512 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1514 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1515 just surfaced after chaning the JOIN procedure.
1517 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1519 * Added silc_client_get_clients_by_list to get client entries
1520 from Client ID list, that is returned for example by JOIN
1521 and USERS command replies. The application should use this
1522 function for example when JOIN command reply is received to
1523 resolve the clients already on the channel (library does not
1524 do that anymore as USERS command reply is not used in the JOIN
1525 procedure anymore). Affected files lib/silcclient/silcapi.h and
1526 lib/silcclient/idlist.c.
1528 * JOIN command reply and USERS command reply returns now SilcBuffer
1529 pointers instead of unsigned char pointers when returning
1530 the client list and mode list.
1532 * Added <Client ID> argument to the JOIN command reply, mainly
1533 for the server to identify for which client the command was
1534 originally sent. Updated protocol specs accordingly.
1536 * Added SilcDlist private_key pointer to the SilcChannelEntry
1537 in the client to support the channel private keys. Affected
1538 file is lib/silcclient/idlist.h.
1540 * Added SilcChannelPrivateKey argument to the function
1541 silc_client_send_channel_message so that application can choose
1542 to use specific private ke if it wants to. If it is not provided,
1543 the normal channel key is used, unless private keys are set.
1544 In this case the first (key that was added first) is used
1545 as the encryption key.
1547 * Implemented the support for channel private key handling.
1548 Implemented the following functions:
1550 silc_client_add_channel_private_key,
1551 silc_client_del_channel_private_keys,
1552 silc_client_del_channel_private_key,
1553 silc_client_list_channel_private_keys and
1554 silc_client_free_channel_private_keys
1556 Affected file lib/silcclient/client_channel.c.
1558 * Added the support for the private keys in the channel message
1559 sending and encryption and in the message reception and
1560 decryption. Affected funtions are
1561 silc_client_send_channel_message and silc_client_channel_message.
1563 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1565 * Added SKE's key verify callback to the client library's
1566 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1568 * Removed the statement that server (or router) must send USERS
1569 command reply when joining to the channel so that the client
1570 knows who are on the channel. Instead, the client list and
1571 client's mode list is now sent in the JOIN command reply to the
1572 client who joined channel. This is better solution.
1574 * Added function silc_server_get_users_on_channel and function
1575 silc_server_save_users_on_channel to the silcd/server.[ch].
1577 * Removed function silc_server_command_send_users from the
1580 * Do not show topic on the client library anymore. The topic is
1581 sent in the command reply notify to the application and the
1582 application must show the topic now.
1584 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Added client searching by nickname hash into the IDENTIFY and
1587 WHOIS commands in the server as they were clearly missing from
1588 them. Affected file is silcd/command.c.
1590 * Fixed a bug in private message receiving in the client library.
1591 The remote ID was freed and it wasn't supposed, now it is
1594 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1596 * Minor fix to the channel payload; allocate the data area, as it
1597 needs to be of specific length.
1599 * If the key agreement port is zero then the operating
1600 system will define the bound port. Affected files are
1601 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1603 * Added new function silc_channel_payload_decrypt into the file
1604 lib/silccore/silcchannel.[ch].
1606 * Moved the channel message etc, check from silc_packet_decrypt
1607 to applications. The library calls now a generic
1608 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1609 when the packet is either normal or special. This was done to
1610 allow more wide range of checking that was not allowed when
1611 the code was in library. Now applications can do virtually any
1612 checks to the packet and return to the library the decision how
1613 the packet should be processed. Affected files are
1614 lib/silccore/silcpacket.[ch].
1616 Added silc_server_packet_decrypt_check to the server and
1617 silc_client_packet_decrypt_check to the client library.
1619 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1620 to send with specified source and destination information.
1622 * Channel message delivery between routers was broken after the
1623 channel key distribution was fixed earlier. The channel key
1624 was used be to distributed to other routers as well which is not
1625 allowed by the protocol. Now this is fixed and channel keys
1626 really are cell specific and the channel message delivery between
1627 routers comply with the protocol specification.
1629 * Fixed various commands in server to check also the global list
1630 for the channel entry and not just the local list. The affected
1631 file silcd/command.c.
1633 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1635 * Added assert()s to buffer formatting and unformatting routines
1636 to assert (if --enable-debug) when error occurs. Affected
1637 file: lib/silcutil/silcbuffmt.c.
1639 * Changed to auto-reconnect to check whether the remote host is
1640 router and register the re-connect timeout if it is. It used
1641 to check that whether we are normal server, but router must do
1642 auto-reconnect with another router as well. Affected file
1645 * Removed the [<key len>] option from CMODE command as the cipher
1646 name decides the key length, nowadays. See the defined ciphers
1647 from the protocol specification.
1649 * Added [<hmac>] option to the CMODE command to define the HMAC
1650 for the channel. Added SILC_CMODE_HMAC channel mode.
1652 * Added [<hmac>] option for the JOIN command so that user can
1653 select which HMAC is used to compute the MACs of the channel
1656 * Added Hmac field to the Channel Message Payload. The integrity
1657 of plaintext channel messages are now protected by computing
1658 MAC of the message and attaching the MAC to the payload. The
1659 MAC is encrypted. Now, it is clear that this causes some
1660 overhead to the size of the packet but rationale for this is that
1661 now the receiver can verify whether the channel message decrypted
1662 correctly and also when private keys are set for the channel the
1663 receiver can decrypt the packet with several keys and check from
1664 the MAC which key decrypted the message correctly.
1666 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1667 lib/silccrypt/silccipher.[ch].
1669 * Added silc_hash_len to return the digest length into the
1670 lib/silcrypt/silchash.[ch].
1672 * Rewrote parts of Silc Channel Payload interface in the
1673 lib/silccore/silcchannel.[ch]. The encode function now also
1674 encrypts the packet and parse function decrypts it.
1676 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1678 * Fixed a minor formatting bug in the SKE's key material processing.
1679 It actually might have processed the keys wrong way resulting
1682 * Redefined the mandatory HMAC algorithms and added new algorithms.
1683 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1684 and hmac-md5 truncated to 96 bits. The mandatory is now
1685 hmac-sha1-96. Rest are optional (including the one that used
1686 to be mandatory). Rationale for this is that the truncated HMAC
1687 length is sufficient from security point of view and can actually
1688 make the attack against the HMAC harder. Also, the truncated
1689 HMAC causes less overhead to the packets. See the RFC2104 for
1692 * Added new [hmac] configuration section. The SKE used to use
1693 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1694 is of course wrong. The official names that must be proposed in
1695 the SKE are the ones defined in the protocol specification
1696 (hmac-sha1-96 for example). The user can configure any hmac
1697 using any hash function configured in the [hash] section. At
1698 least, the mandatory must be configured.
1700 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1702 * Added HMAC list to the SKE proposal list. It has now both
1703 hash algorithm list and HMAC list. This makes the protocol
1704 incompatible with previous versions. The SKE now seems to work
1705 the way it is supposed to work, for the first time actually.
1707 * Defined plain Hash algorithms to the protocol specification.
1710 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1712 * Implemented support for key agreement packets into the server.
1713 Added functions silc_server_key_agreement and
1714 silc_server_send_key_agreement. Other than these functions,
1715 server has nothing to do with this packet.
1717 * Added support for private message key packets into the server.
1718 Added functions silc_server_private_message_key and
1719 silc_server_send_private_message_key.
1723 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1724 called in the protocol's final callback instead in the END
1725 protocol state. This makes a little more sense and in the same
1726 time in client we can use the same protocol routines for normal
1727 key exchange and to key agreement packet handling as well.
1729 * Added to both client's and server's KE protocol context the
1730 SilcSKEKeyMaterial pointer to save the key material. We will
1731 bring the key material to the protocol's final callback by doing
1732 this. The final callback must free the key material.
1734 * Added SKE's packet_send callback into client's KE protocol
1735 context so that the caller can choose what packet sending function
1736 is used. This way we can use different packet sending when
1737 doing normal SKE when doing key agreement packet handling (in
1738 the key agreement packet handling we do not want to encrypt
1741 * Implemented the responder side of the key agreement routines
1742 in the client. The client can now bind to specified port and
1743 accept incoming key negotiation. The key material is passed
1744 to the application after the protocol is over.
1746 * Implemented the processing of incoming Key Agreement packet
1747 in the client. Added function silc_client_key_agreement to
1750 * Implemented the intiator side of the key agreement routines
1751 in the client. The client can now initiate key agreement with
1752 another remote client. The key material is passed to the
1753 application after the protocol is over.
1755 * Created client_keyagr.c to include all the key agreement
1758 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1759 SILC_TASK_CALLBACK except that it is not static.
1761 * Created client_notify.c and moved the Notify packet handling
1762 from the client.[ch] into that file.
1764 * Created client_prvmsg.c and moved all private message and
1765 private message key routines from the client.[ch] into that file.
1767 * Create client_channel.c and moved all channel message and
1768 channel private key routines from the client.[ch] into that file.
1770 * Changed silc_client_get_client_by_id_resolve to resolve with
1771 WHOIS command instead of IDENTIFY command, in the file
1772 lib/silclient/idlist.c.
1774 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Implemented the SKE's responder side to the Client library.
1778 * When FAILURE is received to the protocol do not trust it
1779 blindly. Register a timeout to wait whether the remote closes
1780 the connection as it should do it, only after that process the
1781 actual failure. This was changed to both client and server.
1783 * Added client_internal.h to include some of the structures
1784 there instead of client.h in lib/silcclient/.
1786 * Added function silc_task_unregister_by_callback to unregister
1787 timeouts by the callback function.
1789 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1791 * Some "Incomplete WHOIS info" errors has been appearing on the
1792 log files. Took away the entry->userinfo check from WHOIS
1793 reply sending. The entry->userinfo is now " " if client did not
1794 provide one. I thought this was fixed earlier but something
1795 is wrong still. Let's see if the error still appears.
1797 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1799 * Fixed a minor bug in the login when the channel key is
1800 re-generated in the server. It used to generate the key in
1801 wrong order and thus caused problems in the channel traffic.
1803 * Fixed a minor bug in channel key distsribution after
1804 KICK command. The key was not sent to the router even though
1807 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1809 * Added silc_ske_process_key_material_data as generic routine
1810 to process any key material as the SILC protocol dictates. The
1811 function is used by the actual SKE library but can be used by
1812 applications as well. This relates to the private message keys
1813 and the channel private keys since they must be processed the
1814 same way the normal SILC session keys. The protocol dictates
1815 this. Affected files: lib/silcske/silcske.[ch].
1817 Added also silc_ske_free_key_material to free the
1818 SilcSKEKeyMaterial structure.
1820 * Defined silc_cipher_set_key function to set the key for
1821 cipher without using the object's method function. The affected
1822 files: lib/silccrypt/silccipher.[ch].
1824 * Implemented silc silc_client_add_private_message_key,
1825 silc_client_add_private_message_key_ske,
1826 silc_client_del_private_message_key,
1827 silc_client_list_private_message_keys and
1828 silc_client_free_private_message_keys functions in the
1831 Added functions silc_client_send_private_message_key to send
1832 the Private Message Key payload and silc_client_private_message_key
1833 to handle incoming Private Message Key payload.
1835 * Added Cipher field to the Private Message Key payload to set
1836 the cipher to be used. If ignored, the default cipher defined
1837 in the SILC protocol (aes-256-cbc) is used.
1839 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1841 * Removed lib/silcclient/ops.h file.
1843 Redefined parts of the SILC Client Library API. Created new
1844 file silcapi.h that deprecates the ops.h file and defines the
1845 published Client Library API. Defined also private message key
1846 API and channel private key API into the file.
1848 This is the file that the application must include from the
1849 SILC Client Library. Other files need not be included by
1850 the application anymore.
1852 * Added new key_agreement client operation callback and also
1853 defined the Key Agreement library API for the application.
1855 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1857 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1858 is used by clients to request key negotiation between another
1859 client in the SILC network. If the negotiation is started it
1860 is performed using the SKE protocol. The result of the
1861 negotiation, the secret key material, can be used for example
1862 as private message key.
1864 Implemented the Key Agreement payload into the files
1865 lib/silccore/silauth.[ch].
1867 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1869 * Redefined ciphers for the SILC protocol. Added some new ciphers
1870 and defined the key lengths for the algorithms. Changed the
1871 code accordingly. The default key length is now 256 bits.
1873 * Fixed SKE key distribution function silc_ske_process_key_material
1874 when the key length is more than 128 bits. The default key
1875 length in SILC is now 256 bits.
1877 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1878 to indicate unsupported algorithm.
1880 * Renamed rijndael.c to aes.c and all functions as well.
1882 * Fixed a long standing channel key setting bug in client library.
1883 Weird that it has never surfaced before.
1885 * Fixed bug in channel deletion. If the entire channel is removed
1886 then it must also delete the references of the channel entry
1887 from the client's channel list as the client's channel entry and
1888 the channel's client entry share same memory.
1890 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1892 * Implemented CONNECT and SHUTDOWN commands in the client.
1894 * Implemented CLOSE command to the client.
1896 * Added the function silc_idlist_find_server_by_name into the
1897 files silcd/idlist.[ch].
1899 Added the function silc_idlist_find_server_by_conn into the
1900 files silcd/idlist.[ch].
1902 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1904 * DIE command was renamed to SHUTDOWN. Updated the both code
1907 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1908 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1910 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1913 * Added function silc_server_create_connection function to create
1914 connection to remote router. My server implementation actually
1915 does not allow router to connect to normal server (it expects
1916 that normal server always initiates the connection to the router)
1917 so the CONNECT command is only good for connecting to another
1920 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1922 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1923 or some other client was kicked from the channel.
1925 Implemented the handling of the notify type to both client
1928 Implemented silc_server_send_notify_kicked to send the KICKED
1929 notify. It is used to send it to the server's primary router.
1931 * Implemented the KICK command into server and client.
1933 * Added `query' argument to the silc_idlist_get_client function
1934 to indicate whether to query the client from server or not if
1937 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1938 to indicate that the client is not channel founder.
1942 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1944 * Removed the rng context from SilcPacketContext structure and
1945 changed that the packet routine uses the Global RNG API.
1947 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1949 * Added support for quit message that client can "leave" on the
1950 channel when it quits the SILC. It is ditributed inside the
1951 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1953 Added silc_server_free_client_data that will take the
1954 signoff message as argument.
1956 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1958 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Updated parts of the protocol specification to keep it up
1963 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1965 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1966 payloads in one packet.
1968 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1969 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1970 use now the new List flag.
1972 * Also deprecated the following packet types: REPLACE_ID,
1973 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1975 * Added list support for Notify packet in server.
1977 * Added silc_server_send_notify_channel_change to send the
1978 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1979 the silc_server_send_replace_id.
1981 * Added silc_server_send_notify_nick_change to send the
1982 NICK_CHANGE notify type. Deprecates the function
1983 silc_server_send_replace_id.
1985 * Added silc_server_send_notify_join to send the JOIN notify type.
1986 Deprecates the function silc_server_send_new_channel_user.
1988 * Added silc_server_send_notify_leave to send LEAVE notify type.
1989 Deprecates the function silc_server_send_remove_channel_user.
1991 * Added silc_server_send_notify_cmode and
1992 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1993 types. Deprecates the silc_server_send_set_mode function.
1995 * Added SERVER_SIGNOFF notify type to indicate that server has
1996 quit. This means that all clients on the channel from that
1997 server will drop. This can be also used when netsplit happens.
1999 Deprecated REMOVE_ID packet type since it is not needed anymore
2002 Added silc_server_send_notify_server_signoff to send the
2003 SERVER_SIGNOFF notify type. Deprecates the function
2004 silc_server_send_remove_id.
2006 Added also silc_server_send_notify_signoff to send the
2007 SIGNOFF notify type.
2009 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2010 SILC protocol from this day on. Changed the protocol
2011 specification as well.
2013 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2014 notify type. It is used between routers to notify about
2015 topic changes on a channel.
2017 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2020 * Partly updated the protocol specification to comply with the
2021 changes now made. It is still though a bit outdated.
2023 * The JOIN notify type now takes one extra argument <Channel ID>.
2024 The packet used to be destined to the channel but now the
2025 JOIN type may be sent as list thus it is impossible to
2026 destine it to any specific channel. By adding this argument
2027 it is again possible.
2029 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2031 * Added CREDITS file. The CHANGES and CREDITS file will appear
2032 in the distribution as well.
2034 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2036 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2037 types in the server's silcd/packet_receive.c.
2039 * Implemented CMODE and CUMODE to work in router environment.
2041 * Fixed minor encoding and decoding buglet from the
2042 lib/silccore/silcmode.c.
2044 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2047 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2049 * Changed all SilcConfigServer* and silc_config_server* to
2050 SilcServerConfig* and silc_server_config*, respectively.
2053 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2055 * Associated the ID (client or server ID) to the Authentication
2056 Payload to avoid any possibility of forging. Updated the
2057 protocol specification and the code accordingly.
2059 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * The RSA key length is now save to the RsaKey context in the
2062 key generation process in lib/silccrypt/rsa.c. The key length
2063 is now used to figure out the maximum size of the block allowed
2064 to be encrypted/signed.
2066 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2067 is equivalent to the silc_mp_mp2bin but does not allocate any
2070 * Changed silc_mp_mp2bin API to take length argument. If it is
2071 non-zero then the buffer is allocated that large. If zero, then
2072 the size is approximated using silc_mp_sizeinbase, which however
2075 * Created Global RNG API which is global RNG that application can
2076 initialize. After initializing, any routine anywhere in the
2077 code (including library) can use RNG without allocating a new
2078 RNG object. This was done to allow this sort of use of the
2079 RNG in code that has no chance to allocate RNG object. All
2080 applications currently allocate this and many routines in the
2081 library use this. Affected file lib/silccrypt/silcrng.[ch].
2083 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2084 it to use the Global RNG API.
2086 * Defined Authentication Payload into protocol specification that
2087 is used during SILC session to authenticate entities. It is
2088 used for example by client to authenticate itself to the server
2089 to obtain server operator privileges.
2091 Implemented this payload into the lib/silccore/silcauth.[ch].
2092 Implemented also routines for public key based authentication
2093 as the new protocol specification dictates.
2095 Moved definitions of different authentication methods from
2096 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2098 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2099 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2100 silc_pkcs_verify_with_hash functions into the file
2101 lib/silccrypt/silcpkcs.[ch].
2103 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2105 * The client entry's userinfo pointer must be always valid.
2106 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2107 will fail since it requires the userinfo. Now, the userinfo
2108 is allocated as "" if actual userinfo does not exist. Actually,
2109 it must exist and it is totally Ok to drop client connections
2110 that does not announce the userinfo. However, we will make
2111 this workaround for now.
2113 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2114 to return the remote port by socket.
2116 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2118 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2119 SILC_SERVER_PENDING_EXEC and added an new macro
2120 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2121 data or when error occurs while processing the pending command.
2123 Added new argument `destructor' into silc_server_command_pending
2124 and to the SilcServerCommandPending object. This destructor is
2125 now called after calling the pending callback or if error occurs
2126 immediately. If error occurs the actual pending callback won't
2127 be called at all - only the destructor. The destructor may be
2128 NULL if destructor is not needed.
2130 All this applies for client library code as well. Similar
2131 changes were made there as well for the pending commands.
2133 In the client, the application must now allocate the
2134 SilcClientCommandContext with the silc_client_command_alloc
2137 * Added reference counter to the SilcServerCommandContext. Added
2138 function silc_server_command_alloc and silc_server_command_dup
2141 Same type of functions added to the client library for the same
2144 * Removed the cmd_ident from IDListData away since it is now
2145 global for all connections. It is the command identifier used
2146 in command sending and with pending commands. The affected file
2149 * Added reference counter to the SilcSocketConnection objecet to
2150 indicate the usage count of the object. The object won't be
2151 freed untill the reference counter hits zero. Currently only
2152 server uses this, and client ignores it. The client must be
2153 set to use this too later. The affected files are
2154 lib/silccore/silcsockconn.[ch]. Added also the function
2155 silc_socket_dup to increase the reference counter.
2157 This was mainly added because it is possible that the socket
2158 is removed underneath of pending command or other async
2159 operation. Now it won't be free'd and proper DISCONNECTING
2160 flags, etc. can be set to avoid sending data to connection that
2161 is not valid anymore.
2163 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2164 the connection. After that it sets SILC_SET_DISCONNECTED.
2165 It is, however, possible that the socket data is not still freed.
2166 The silc_server_packet_process now checks that data is not
2167 read or written to connection that is DISCONNECTED. The socket
2168 get's freed when the reference counter hits zero.
2170 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Changed the client operation API: channel_message operation's
2173 `sender' is now the client entry of the sender, not the nickname
2174 and the `channel' is the channel entry, not the channel name.
2176 In the private_message operation the `sender' is now also the
2177 client entry of the sender not the nickname.
2179 Affected file is lib/silcclient/ops.h and all applications
2180 using the client operations.
2182 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2184 * Moved the calling of ops->connect() from connect_to_server_final
2185 into receive_new_id functin since that is the point when the
2186 client is actually allowed to send traffic to network. The
2187 affected file is lib/silcclient/client.c.
2189 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2192 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2193 (if needs broadcasting) instead of broadcasting the packets one
2194 by one which would make a burst in the network traffic.
2196 * Added `broadcast' argument to the functions in silcd/server.[ch]
2197 silc_server_create_new_channel[_with_id] to indicate whether
2198 to send New Channel packet to primary router.
2200 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Added new function into the silcd/server.[ch] files:
2203 silc_server_create_new_channel_with_id to create new channel with
2204 already existing Channel ID.
2206 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2207 lib/silccore/silcpacket.h. This packet is used t send list of
2208 Set Mode payloads inside one packet. Server uses this to set
2209 the modes for the channels and clients on those channels, that it
2210 announced to the router when it connected to it. The protocol
2211 specification has been updated accordingly.
2213 * The silc_server_new_channel did not handle the packet coming
2214 from normal server as it normally does not send that. However,
2215 when it announces its channels it does send it. Implemented
2216 the support for that.
2218 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2219 into the file lib/silccore/id.h.
2221 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2223 * Fixed memory leaks in the functions silc_idlist_del_client,
2224 silc_idlist_del_channel and silc_idlist_del_server in the file
2225 silcd/idlist.c. All of those leaked like a sieve.
2227 * Fixed some small memory leaks in the client's function
2228 silc_client_notify_by_server.
2230 * Added functions into silcd/server.c: silc_server_announce_clients,
2231 silc_server_announce_channels and silc_server_announce_server.
2232 These functions are used by normal and router server to announce
2233 to its primary router about clients, channels and servers (when
2234 router) that we own. This is done after we've connected to the
2237 These functions effectively implements the following packet types:
2238 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2239 and SILC_PACKET_NEW_ID_LIST.
2241 * Added new functions into the silcd/packet_receive.[ch]:
2242 silc_server_new_id_list, silc_server_new_channel_list and
2243 silc_server_new_channel_user_list to handle the incoming
2244 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2246 * Added support of changing Channel ID in the function
2247 silc_server_replace_id. If the server that announces a channel
2248 to the router already exists in the router (with same name but
2249 with different Channel ID), router is responsible to send
2250 Replace ID packet to the server and force the server to change
2251 the Channel ID to the one router has.
2253 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2254 client that the Channel ID has been changed by the router. The
2255 normal server sends this to the client. Client must start using
2256 the new Channel ID as the channel's ID.
2258 Implemented handling of this new type into lib/silcclient/client.c
2259 into the function silc_client_notify_by_server.
2261 * Added new function silc_idlist_replace_channel_id into the files
2262 silcd/idlist.[ch] to replace the Channel ID.
2264 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2266 * Call silc_server_command_identify_check always when processing
2267 the IDENTIFY command in silcd/command.c
2269 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2272 send keepalive packets. The packet can be sent by clients,
2273 servers and routers.
2275 Added function silc_socket_set_heartbeat into the file
2276 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2277 If not set, the heartbeat is not performed. The actual
2278 heartbeat is implemented in the low level socket connection
2279 library. However, application is responsible of actually
2282 Added silc_server_send_heartbeat to send the actual heartbeat
2283 packet into silcd/packet_send.[ch]. Server now performs
2284 keepalive with all connections.
2286 * Added silc_task_get_first function into lib/silcutil/silctask.c
2287 to return the timeout task with shortest timeout. There was a bug
2288 in task unregistration that caused problems. TODO has been
2289 updated to include that task system must be rewritten.
2291 * The client library will now resolve the client information when
2292 receiving JOIN notify from server for client that we know but
2293 have incomplete information.
2295 * Rewrote parts of silc_server_remove_from_channels and
2296 silc_server_remove_from_one_channel as they did not remove the
2297 channel in some circumstances even though they should've.
2299 * Encryption problem encountered in server:
2301 The LEAVE command used to send the Channel Key packet to the
2302 router immediately after generating it. However, the code
2303 had earlier sent Remove Channel user packet but not immediately,
2304 ie. it was put to queue. The order of packets in the router
2305 was that Channel Key packet was first and Remove Channel User
2306 packet was second, even though they were encrypted in the
2307 reverse order. For this reason, MAC check failed. Now, this
2308 is fixed by not sending the Channel Key packet immediately but
2309 putting it to queue. However, this is more fundamental problem:
2310 packets that are in queue should actually not be encrypted
2311 because packets that are sent immediately gets encrypted
2312 actually with wrong IV (and thus MAC check fails). So, packets
2313 that are in queue should be encrypted when they are sent to
2314 the wire and not when they put to the queue.
2316 However, the problem is that the current system has not been
2317 designed to work that way. Instead, the packet is encrypted
2318 as soon as possible and left to the queue. The queue is then
2319 just purged into wire. There won't be any fixes for this
2320 any time soon. So, the current semantic for packet sending
2323 o If you send packet to remote host and do not force the send
2324 (the packet will be in queue) then all subsequent packets to the
2325 same remote host must also be put to the queue. Only after the
2326 queue has been purged is it safe again to force the packet
2329 o If you send all packets immediately then it safe to send
2330 any of subsequent packets through the queue, however, after
2331 the first packet is put to queue then any subsequent packets
2332 must also be put to the queue.
2334 Follow these rules and everything works fine.
2336 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2338 * Added new function silc_server_remove_clients_by_server to
2339 remove all client entries from ID list when the server connection
2340 is lost. In this case it is also important to invalidate all
2341 client entires as they hold the invalid server entry. This
2342 fixes fatal bug when server has lost connection and will reconnect
2345 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2347 * Made some sanity checks to silc_server_daemonise like to check
2348 whether the requested user and group actually exists.
2350 * Added sanity check to SKE's silc_ske_responder_finish to check
2351 that the public and private key actually is valid.
2353 * Invalidate the client's nickname when receiving Replace ID
2354 packet and the Client ID is being replaced. This means that the
2355 server will query the nickname if someone needs it (client)
2358 * Sort the ID Cache in client library when the ID Cache data
2359 has changed (needs sorting).
2361 * Do not allow for SILC client to create several connections to
2362 several servers. The client does not support windows right now
2363 and generating multiple connections causes weird behaviour.
2365 Irssi-silc client does support windows and can handle several
2366 connections without problems, see: www.irssi.org and SILC plugin.
2368 * Fixed some places where client was added to the IDList. The
2369 rule of thumb is following (in order to get everything right):
2370 If the client is directly connected local client then the
2371 `connection' argument must be set and `router' argument must be
2372 NULL to silc_idlist_add_client function. If the client is not
2373 directly connected client then the `router' argument must
2374 bet set and the `connection' argument must be NULL to the
2375 silc_idlist_add_client function.
2377 * The funtion silc_server_packet_send_local_channel actually did
2378 not check whether the client was locally connected or not. It
2379 does that now. Fixed a bug related to LEAVE command.
2381 * Fixed Remove Channel User payload parsing bug in server's
2382 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2384 * The server's silc_server_save_channel_key now checks also the
2385 global ID list for the channel as it might not be in the local
2386 list. Fixed a bug related to LEAVE command.
2388 * Is this the end of the [<unknown>] buglet that has been lurking
2389 around for a long time? A little for loop fix in server's
2390 silc_server_command_whois_parse that is used by both IDENTIFY
2391 and WHOIS command. At least, this was a clear bug and a cause
2392 of one type of [<unknown>] buglet.
2394 * WHOIS and IDENTIFY commands call the function
2395 silc_server_command_[whois/identify]_check function even if
2396 we are not router server.
2398 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2400 * Added --with-gmp configuration option. If set the GMP
2401 is always compiled in the SILC source tree. If not set then
2402 it is checked whether the system has the GMP3 installed. If
2403 it has then the GMP won't be compiled (the system's headers
2404 and library is used), if it doesn't have it then the GMP is
2405 compiled in the SILC source tree.
2407 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2409 * Changed RSA private exponent generation to what PKCS #1
2410 suggests. We try to find the smallest possible d by doing
2411 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2412 not security fix but optimization.
2414 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2416 * Added new config entry [Identity] to fork the server and run
2417 it as specific user and group. A patch from Bostik.
2419 * Imported Dotconf configuration library into lib/dotconf.
2420 This will be used to create the SILC configuration files later.
2421 It will appear in the distsribution after this commit.
2423 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2425 * A big code auditing weekend happening. Auditing code for
2426 obvious mistakes, bugs and errors. Also, removing any code
2429 Removed files for being obsolete:
2431 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2432 inline in the file lib/silcutil/silcbuffer.h)
2434 o lib/silcutil/silcbufutil.c (the header has inline versions)
2436 Changed code to fix possible error conditions:
2438 o The buffer formatting routines now check that the destination
2439 buffer really has enough space to add the data. This applies for
2440 both buffer formatting and unformatting
2441 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2442 unformatting was changed to accomodate following rules:
2443 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2444 sent to the function while XXX_*STRING will not allocate or copy
2445 the data into the buffer. Instead it sets the pointer from the
2446 buffer into the pointer sent as argument (XXX_*STRING used to
2447 require that the pointer must be allocated already). This change
2448 makes this whole thing a bit more consistent and more optimized
2449 (note that the data returned in the unformatting with XXX_*STRING
2450 must not be freed now). The routines return now -1 on error.
2452 o Tried to find all code that use buffer_format and buffer_unformat
2453 and added return value checking to prevent formatting and
2454 especially unformatting errors and possible subsequent fatal
2457 o Changed ske->x and ske->KEY to mallocated pointers in
2458 lib/silcske/silcske.h. Fixed possible data and memory leak.
2460 o Added return value checking to all *_parse* functions. Fixed
2461 many memory leaks as well.
2463 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2464 so that buffer overflows would not happen. All code now also
2465 checks the return value as it can fail.
2467 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * Added reconnection support to server if the normal server looses
2470 its connection to the router (for example if router is rebooted).
2471 The server performs normal reconnection strategy implemented
2472 to the server. Affected file silcd/server.c.
2474 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2476 * Added new packet type SILC_PACKET_SET_MODE that is used to
2477 distribute the information about changed modes (for clients,
2478 channels and clients channel modes) to all routers in the
2479 network. Updated the protocol specification accordingly.
2481 Added functions into silcd/packet_send.c and
2482 silcd/packet_receive.c: silc_server_send_set_mode,
2483 silc_server_set_mode.
2485 Added new files silcmode.[ch] into lib/silccore that implements
2486 the encoding and decoding of Set Mode Payload. Added new type
2487 SilcSetModePayload. Moved the definitions of different modes
2488 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2490 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2492 * Oops, a little mistake in server's connection authentication
2493 protocol. The protocol is not ended with FAILURE but with
2494 SUCCESS if the authentication is Ok. :) Affected file is
2497 * Implemented NICK_CHANGE notify handling in server in the file
2498 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2499 the local clients on the channel. After the changing nickname
2500 in router environment snhould work and the [<unknown>] nickname
2501 should appear no more.
2503 The silc_server_replace_id function that receives the Replace ID
2504 payload now sends the NICK_CHANGE notify type also in the file
2505 silcd/packet_receive.c
2507 * Changed WHOIS and IDENTIFY command to support the maximum amount
2508 of arguments defined in protocol specs (3328 arguments). This
2509 fixed a bug that caused problems when there were more than three
2512 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Added extra parameter, command identifier, to the
2515 silc_client_send_command so that explicit command identifier
2518 Changed that ID list routines uses specific command identifier
2519 when sending WHOIS/IDENTIFY requests to the server so that they
2520 can be identified when the reply comes back.
2522 Affected files lib/silcclient/command.[ch],
2523 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2525 * Added `sender' argument to silc_server_packet_send_to_channel
2526 to indicaet the sender who originally sent the packet to us
2527 that we are now re-sending. Ignored if NULL. Affected file
2528 silcd/packet_send.[ch].
2530 * Added some server statistics support in silcd/server_internal.h
2531 SilcServerStatistics structure and around the server code. Also
2532 send some nice statistics information when client is connecting
2535 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2537 * Fixed channel ID decoding in server's JOIN command reply in
2538 silcd/command_reply.c
2540 * Fixed braodcasting of replace ID payload to not to send it if
2541 we are standalone server in silcd/packet_receive.c.
2543 * Fixed all channel message sending routines to not to send
2544 packets to clients that has router set, since they are routed
2545 separately in the same function earlier. Affects file
2546 silcd/packet_send.c and all channel packet sending functions.
2548 * In USERS reply, res_argv[i] are not allocated, the table
2549 is allocated. Thus changed that free the table, not its
2552 * In server's whois_check and identify_check if the client is
2553 locally connected do not send any WHOIS commands - they are not
2556 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * Fixed some minor bugs in client when sending WHOIS command. The
2559 arguments was in wrong order.
2561 * Removed statis function add_to_channel from server in
2562 silcd/command.c that was previously used with the joining but
2565 * Tested USERS command in router environment successfully with two
2566 routers, two servers and two clients.
2568 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Reorganized the USERS command and command reply in client library
2571 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2572 When the command is given by user we register a pending command
2573 callback that will reprocess the command after the reply has been
2574 received from the server. When reprocessing the packet we then
2575 display the information. Thus, the USERS information is displayed
2576 now in the command callback instead of in the command reply
2577 callback. The processing of the command is same as previously
2578 when server has sent the command reply in the JOINing process.
2580 * Added to USERS command in silcd/command_reply.c to join the client,
2581 we didn't use to know about, to the channel after we've created
2582 a client entry for it. Also, for clienet we did know already still
2583 check whether it is on the channel or not and add it if not.
2585 * Removed silc_server_command_join_notify as the function and its
2588 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2590 * Changed the client's pending command handling to the same as the
2591 server's pending command handling. It is also now possible to
2592 execute command reply functions from other command reply
2593 function as the function callbacks for commands and command
2594 replies are one and same. The pending commands are not static
2595 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2596 in client connection context. Thus, pending commands are server
2597 connection specific as it is convenient.
2599 Changed the function silc_client_command_pending and
2600 silc_client_command_pending_del and added new function
2601 silc_client_command_pending_check. Removed the
2602 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2605 * Added cmd_ident, current command identifier, to the client
2606 connection context in lib/silcclient/client.h to keep track on
2607 command identifiers used in command sending. Client's command reply
2608 function handling now supports the mandatory command identifiers.
2610 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2611 funtions in client to fully support pending command callbacks.
2613 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2614 as one of the arguments to the application in the command reply
2617 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2618 before first releasing SILC but came back. Now it is removed again
2619 and should come back nomore. The FORWARDED flag was used only
2620 by the JOINing procedure by forwarding the command packet to router.
2621 Now, the JOINing procedure has been changed to more generic (due
2622 to various router environment issues) and FORWARDED is not needed
2623 anymore for anything. The protocol specification is yet to be
2626 Now, removed silc_server_packet_forward from server and the flag
2627 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2629 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Renamed NAMES command to USERS command. The NAMES was named that
2632 due to historical reasons. Now it is renamed. Also, rewrote
2633 parts of the USERS command. The nickname list is not sent anymore
2634 by the server. Only Client ID and mode lists are sent in the USERS
2635 command. Changed this also to the protocol specification.
2637 The client now resolves the names and stuff after it receives
2638 the USERS list from the server when joining to the channel.
2640 * WHOIS and IDENTIFY commands has been changed to support multiple
2641 Client ID's per command. One can now search for multiple users
2642 in the network by sending only one WHOIS or IDENTIFY command.
2643 Changed the code and the protocol specifications.
2645 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2646 uses silc_server_command_whois_parse to parse the request. */
2648 * If normal server, do not parse the WHOIS and IDENTIFY requests
2649 before sending it to the router. Saves some time.
2651 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2653 * Fixed JOIN command on client library. Wrong number of arguments
2654 used to crash the client.
2656 * Added silc_server_channel_has_global function to check whether
2657 channel has global users or not.
2659 * Added silc_server_channel_has_local function to check whether channel
2660 has locally connected clients on the channel.
2662 * The silc_server_remove_from_one_channel now checks whether the
2663 channel has global users or not after given client was removed from
2664 the channel. It also checks whether the channel has local clients
2665 on the channel anymore. If it does not have then the channel entry
2666 is removed as it is not needed anymore.
2668 * The silc_server_notify now checks on JOIN notify whether the joining
2669 client is one of locally connected or global. If it is global then
2670 the channel has now global users on the channel and that is marked
2671 to the channel entry. Also, it now saves the global client to
2672 global list who is joining and JOINs it to the channel. This is
2673 for normal server, that is.
2675 Changed silc_server_send_notify_on_channel,
2676 silc_server_packet_relay_to_channel and
2677 silc_server_packet_send_to_channel check if we are normal server
2678 and client has router set (ie. global client) do not send the
2679 message to that client, as it is already routed to our router.
2681 * Implemented LEAVE notify type handling in silc_server_notify
2684 * Tested LEAVE command in router environment successfully. Tested
2685 with two routers, two servers and two clients.
2689 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2691 * Implemented SIGNOFF notify type handling in silc_server_notify
2694 * silc_server_remove_id now removes the client entry from all channels
2695 it has joined and thusly sends SIGNOFF notify type.
2697 * Rewrote the NAMES list generation in server by removing two excess
2698 loops. The lists are created now inside one loop.
2700 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * silc_server_remove_channel_user checks now also global list
2703 for channel and client.
2705 * silc_server_new_channel_user checks now both local and global
2706 list for channel and client. Fixed a bug in client id decoding.
2707 Used to decode wrong buffer.
2709 * silc_server_channel_message checks now both local and global
2710 list for channel entry.
2712 * Tested channel joining (hence JOIN) in router environment
2713 successfully. Tested with two routers, two servers and two
2716 * Tested channel message sending in router environment successfully.
2718 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2720 * Added silc_server_save_channel_key into server.[ch] to save the
2721 received channel key in Channel Key payload processing. It is
2722 also used in JOIN command reply handling.
2724 Equivalent function silc_client_save_channel_key added into
2725 client.[ch] into client library.
2727 * Changed JOIN command reply to send information whether the channel
2728 was created or not (is existing already) and the channel key
2729 payload. Changed protocol specs accordingly.
2731 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2732 the request was sent by ID and not by nickname. Crashed on
2735 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2738 now correctly save the received data.
2740 * silc_server_free_sock_user_data now notifies routers in the
2741 network about entities leaving the network.
2743 At the same time implemented functions silc_server_remove_id
2744 and silc_server_send_remove_id to receive and send REMOVE_ID
2745 packets. The packet is used to notify routers in the network
2746 about leaving entities. The ID removed will become invalid in
2749 * Added function silc_idlist_del_server into server. Removes and
2750 free's server entry from ID list.
2752 * silc_server_private_message function now checks, if we are router,
2753 that the destination ID really is valid ID, naturally.
2755 * In router when NEW_ID packet is received (for new client) the
2756 hash of the Client ID is saved in the ID Cache but the
2757 client->nickname is set to NULL, instead of putting the hash
2760 IDENTIFY command now also checks that client->nickname must be
2761 valid. If it is not if will request the data from the server who
2762 owns the client. Added new function
2763 silc_server_command_identify_check.
2765 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2766 to set the command to already allocated Command Payload.
2768 * Tested private message sending in router environment with two
2769 routers, two servers and two clients. Fixed minor bugs and now
2772 * Fixed segfault from client's NAMES command. Used to crash if
2775 * Forwarded packets must not be routed even if it is not destined
2776 to the receiver. Changed server code comply with this.
2778 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2780 * Added `require_reverse_mapping' boolean value to ServerParams
2781 structure. If TRUE (not default) the server will require that
2782 the connecting host has fully qualified domain name.
2784 If the reverse mapping is not required and hostname could not be
2785 found the IP address is used as hostname.
2787 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Implemented version string checking to both client and server.
2790 The check is incomplete currently due to the abnormal version
2791 strings used in development version of SILC.
2793 * Changed all command functions in server to use the new
2796 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2798 * Changed char *data to unsigned char *data in ID Cache system to
2799 support binary data as ID Cache data. Changed code to support
2800 binary data in lib/silccore/idcache.c.
2802 * Renamed silc_server_packet_relay_command_reply to
2803 silc_server_command_reply as it is normal packet receiving
2804 function. Rewrote the function to accept command replys for
2805 servers and not only for clients.
2807 * Mark remote router always as registered server if we are connecting
2808 to it. Otherwise, commands sent by the router to us are ignored.
2810 * All ID List find routines now returns the ID Cache Entry pointer
2811 as well if requested.
2813 * WHOIS command works now in router environment, tested with two
2814 routers, two servers and two clients.
2816 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2817 in router environment (as it is almost equivalent to WHOIS) but
2818 hasn't been tested thoroughly. Added new functions:
2820 silc_server_command_identify_parse
2821 silc_server_command_identify_send_reply
2822 silc_server_command_identify_from_client
2823 silc_server_command_identify_from_server
2825 * Disabled route cache adding because adding two different ID's with
2826 same IP replaces the old cache entry thus giving wrong route.
2827 The entry->router->connection is always the fastest route anyway
2828 so route cache may not be needed. Of course, new routes maybe
2829 established after receiving the ID when the entry->router->connection
2830 might not be anymore the most optimal.
2832 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2834 * Add route cache for received ID for fast routing.
2836 * Added silc_server_packet_route to route received packet on router
2837 that is not destined to us.
2839 * Renamed silc_server_get_route to silc_server_route_get.
2841 * Added id_string and id_string_len fields into SilcServer to
2842 include encoded ServerID for fast comparing without excess
2843 encoding of the ID's.
2845 * Cleaned up WHOIS command on server side. Added following static
2848 silc_server_command_whois_parse
2849 silc_server_command_whois_check
2850 silc_server_command_whois_send_reply
2851 silc_server_command_whois_from_client
2852 silc_server_command_whois_from_server
2854 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2855 arguments in command replies. All command functions should be
2856 updated to use this macro.
2858 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2860 * Minor typo fixes on command reply handling on server.
2862 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Added silc_server_command_add_to_channel internal routine to add
2865 the client to the channel after router has created the channel and
2866 sent command reply to the server.
2868 * Added generic silc_server_send_command to send any command from
2871 * Use static buffer with ID rendering instead of duplicating data.
2873 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2875 * Fixed a channel user mode bug when joining to a channel server gave
2876 everybody channel founder rights, oops.
2878 * We mark ourselves as the router of the incoming server connection
2879 if we are router ourselves. This way we can check in some packet
2880 sending functions whether it is locally connected server. For
2881 incoming router connections we put NULL.
2883 * For router sending packets locally means now always sending the
2884 packet cell wide; to local clients and local servers. For normal
2885 server sending packet locally means sending it to only local
2888 * Fixed the JOIN command to really work in router environment. If the
2889 channel is created it is always created by the router. Router is
2890 also responsible of making the initial joining to the channel,
2891 sending JOIN notify to the sending server and distributing
2892 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2893 does not exist server doesn't do anything else but forward the
2894 command to the router which performs everything.
2896 * Added silc_server_send_channel_key function to send the Channel Key
2899 * Added silc_server_create_channel_key to create new channel key. The
2900 channel key is now re-generated everytime someone joins or leaves
2901 a channel, as protocol dictates. Note: channel->key_len is the
2904 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2906 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2907 packet_receive.[ch] to separate packet sending and receiving
2908 routines. The server.[ch] now includes everything else including
2909 actual packet processing (writing and reading data) and other
2912 Renamed silc_server_private_message_send_internal to
2913 silc_server_send_private_message. The routine is still though
2914 used only to relay private messages as server does not send
2915 private messages itself.
2917 Renamed silc_server_new_channel to silc_server_create_new_channel
2918 and added new function sicl_server_new_channel that handles the
2919 incoming New Channel packet. Added also new sending function
2920 silc_server_send_new_channel to send New Channel Payload.
2922 * Added new function silc_server_notify to process incoming notify
2923 packet to the server/router. Server may then relay the notify
2924 to clients if needed.
2926 * Added new function silc_server_new_channel_user to process incoming
2927 New Channel User packet. Router will redistribute the packet and
2928 send JOIN notify to its local clients and locally connected servers
2929 if needed. Normal server will send JOIN notify to its local client
2930 on same channel when received this packet. Added also corresponding
2931 sending function silc_server_send_new_channel_user to sent the
2934 * Added boolean route argument to send_notif_to_channel and
2935 packet_send_to_channel functions to attempt to route the packet
2936 if it is TRUE and send only locally if it is FALSE.
2938 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2940 * silc_server_replace_id now broadcasts the received replace ID
2941 packet if it is not broadcast packet already. The router must
2942 broadcast to inform other routers about changed ID.
2944 * Added backpointer to server's router into SilcServer context in
2945 silcd/server_internal.h.
2947 * Fixed silc_server_packet_broadcast to send correct broadcast
2950 * The channel key is now distributed to the local client as soon
2951 as it is received from the router (in router environment) so that
2952 no other packet may be sent for the channel until client has
2955 * silc_server_remove_channel_user now broadcasts the received
2956 Remove Channel User packet if it is not broadcast packet already.
2957 The router must broadcast to inform other routers about removed
2960 * Added users field into SilcPacketContext that is a reference count
2961 of the context. One can increase the reference count by calling
2962 silc_packet_context_dup which is now changed to just increase the
2963 reference count instead of duplicating the data. The reference
2964 count is decresed by calling silc_packet_context_free that will
2965 free the data after the reference count hits zero.
2967 For now on the packet context and everything allocated into it
2968 (including the raw packet from network) must be freed by calling
2969 the new silc_packet_context_free function. Added also new function
2970 silc_packet_context_alloc that must be used now to allocate the
2971 context. This also means that if a routine is asynchronous from
2972 silc_[client/server]_packet_parse_type the packet context must
2973 be duplicated by calling silc_packet_context_dup. Otherwise it
2974 gets free'd after silc_[client/server]_packet_parse_type returns.
2975 Also, one must remember that if packet is duplicated then its
2976 reference count must be decresed by calling the free function as
2977 many times as it was duplicated.
2979 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2980 from both client and server.
2982 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Made joining to a channel working in router environment.
2986 * Cleaned up JOIN command on server side and create function
2987 silc_server_command_join_channel internal routine to make the
2990 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Changed silc_command_pending list to SilcDList. Also, added
2993 `ident' field to SilcServerCommandPending structure to identify
2994 the reply and to call correct callback.
2996 Added silc_server_command_pending_check function to replace the
2997 corresnponding macro. The silc_command_pending list is not
3000 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3001 to set identifier to previously allocated Command Payload. It
3002 is used to set identifier for command when resending Command
3005 * Added silc_command_payload_encode_payload to encode Command
3006 Payload buffer from SilcCommandPayload structure.
3008 * Added silc_argument_payload_encode_payload to encode Argument
3009 payload buffer from SilcArgumentPayload structure.
3011 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * Changed WHOIS command to support router connection on server side.
3014 The whois request is always sent to router unless the server is
3015 standalone server. After server has received the reply from the
3016 router will it send the reply to the client.
3018 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3019 broadcast received broadcast packet. The function is used only
3020 by router. The broadcast packet is always sent to the router's
3023 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3024 render given ID to printable string, for log files for example.
3026 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3028 * Made basic router to router connections working. At least they
3029 can now connect to each other but nothing really works the way
3030 they are supposed - yet.
3032 * Added new initiator token to RouterConnection configuration
3033 file in silcd/serverconfig.[ch]. It is used to tell whether we
3034 are the initiator to the remote router or whether we'll expect
3035 the other end to connect.
3037 * Moved registering of listener task to silc_server_init, hence
3038 the server starts listenning as soon as it is run, even if it
3039 does not have connections to other routers. Let's see how well
3042 * Changed default connection retry timeouts for more suitable in
3045 * Removed cipher and such arguments from silc_idlist_add_client
3046 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3047 Added new function silc_idlist_add_data to add the keys and stuff
3050 * Added SilcIDListData structure and added it to SilcClientEntry
3051 and SilcServerEntry as their first field in the structure. This
3052 way we can explicitly cast the ID entries to the SilcIDListData
3053 structure and get common data for the entries. In past, we had
3054 to first check what type of connection it is and then cast it to
3055 correct ID entry type. Now, we can directly cast the opaque
3056 pointer to the SilcIDListData (no matter what ID entry it actually
3057 is) and get the data needed.
3059 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3062 in some circumstances even if threre were timeout tasks, though not
3063 IO tasks, but tasks anyway. Now fixed.
3065 * Defined SilcServerConnection structure to hold connection specific
3066 stuff about directly connected servers and routers. The definition
3067 is currently in silcd/server_internal.h. I thought about having
3068 a bit more important role fro this struct but for now it is used
3069 only when connecting to other server (or router actually).
3071 * Added connecting retry support in server when connecting to
3072 router(s). The retry feature implement exponential backoff
3073 algorithm. Also, added SilcServerParams structure to hold default
3074 parameters for server. For now, it include these retry settings
3075 and are hard coded. After server is moded to be as Silc Server
3076 Library this structure will be more important.
3078 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3080 * Changed client librarys channel->clients table to SilcList and
3081 changed code accordingly.
3083 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3085 * Changed client's channel table to SilcList and changed code
3086 accordingly. Also changed SilcChannelClientEntry to include back-
3087 pointer to the channel so that client entry can use that structure
3088 as list as well and we have fast cross-reference to the channel.
3089 This change dramatically decreased the complexity of channel
3090 handling with client entry and vice versa (removed one extra
3091 loop when searching for channel entry from many functions).
3093 * Changed server->sim from table to SilcDList and changed code
3096 * NAMES command can now be used from user interface. It will show
3097 the user list on the channel, neatly.
3099 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3100 Code now saves realname of the user if it becomes available.
3102 * Renamed configure.in to configure.in.pre and made ./prepare
3103 script to automatically add correct version string to
3104 configure.in which it creates from configure.in.pre.
3106 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * NAMES command reply now shows users mode with the nickname when
3111 * Moved silc_client_ch[u]mode[_char] functions from
3112 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3113 place sucks, they are utility functions and should be in some
3116 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3118 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3121 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3125 * Added TRQ (efficient deque and list library) into lib/trq. This is
3126 a very good list library that is currently used in the SILC. Defined
3127 SilcList API over the library because I didn't like the API very
3128 much. See lib/trq/silclist.h for the API and examples of how to
3129 use the API. Fixed various places in the code to use the new
3130 SilcList API. The SilcList is meant for lists that has a structure
3131 already defined as a list. It is not suitable to add just some
3132 context to the list (in TRQ, the context is the list actually).
3134 So, I defined SilcDList that can be used for the purpose where
3135 predefined list structure does not exit. This can be used as
3136 such list. Now some context just can be added to the SilcDList.
3137 Currently this list is not used in the SILC just yet, though there
3138 are a lot places where this can replace dynamically allocated
3139 tables and I will fix these places, later, to use SilcDList.
3140 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3141 and use TRQ internally).
3143 Also fixed some annoying warning messages that the original TRQ
3144 code generated. Also minor changes to TRQ's Makefile.in.
3146 * Added support for querying by Client ID to both WHOIS and
3147 IDENTIFY commands into server, as required by the protocol.
3149 * Removed method function pointers from SilcBuffer structure. They
3150 weren't used to anything and just increased the context size for
3151 no good reason. This change also made silc_buffer_alloc and
3152 silc_buffer_free functions inline functions.
3154 * Disabled command flooding detection support until it's fixed so
3155 that it accepts commands in but does not execute them more than once
3158 * Added silc_net_localhost(), to return local hostname, into
3159 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3160 that must be initialized before calling silc_client_init.
3162 * Added new function: silc_server_send_notify_on_channels to send
3163 notify messages to all channels client has joined. It is assured
3164 that the message is sent only once per client.
3166 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3167 lib/silcutil/silcutil.[ch] as silc_format function. The new
3168 function is generic and is used by server as well, not only by
3169 the logging routines.
3171 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3172 the provided version string was not acceptable. Added new function:
3173 silc_ske_check_version into lib/silcske/silcske.h. The function
3174 must be implemented by the application (client or server) and it
3175 does not reside in the SKE library. The function checks the version
3176 string remote end sent.
3178 * Added back pointers (to opaque context and to SilcSocketConnection)
3179 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3181 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3182 duplicate packet context structure.
3184 * Changed `notify' client operation to send same arguments as client
3185 receives from server except for ID's. ID's are mapped to correct
3186 ID entry and that is returned. Also, if channel entry is not sent
3187 by server but the notify is for channel the channel entry is sent
3188 to application (otherwise application doesn't know that it is for
3189 channel (library gets it from packet's Destination ID)).
3191 * Added silc_client_remove_from_channels into client library to
3192 remove a client from all channels it has joined to. Used when
3193 received SIGNOFF notify from server. Added also new function
3194 silc_client_replace_from_channels to replace old ID entry with
3195 new ID entry on all channels. Used when received NICK_CHANGE
3198 * Fixed ID Cache list handling in silc_idlist_get_client in
3199 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3200 to get (or query) client by ID.
3202 * Updated TODO list.
3204 * Added connection authentication status message defined by the
3205 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3206 support for these into the code in client and server side.
3208 * Added generic function silc_client_send_command to send any command
3209 with variable argument list. Application should use this function
3210 to send commands if the command functions provided by the library
3211 does not suite for the application's user interface needs.
3213 * Added new `failure' client operation. Application is notified about
3214 received failure packet if client is executing a protocol. In this
3215 case the protocol's execution has failed.
3217 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3218 is required by the protocol.
3220 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3221 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3224 * Added status flag to SilcSKE object to indicate realtime status
3225 of the SKE protocol.
3227 * Application receives now exactly same command reply arguments as
3228 the library receives from server. However, if ID is received the
3229 corresponding ID entry is returned to the application (eg. Client
3230 ID is mapped to correct SilcClientEntry entry and that is returned).
3231 Changed command_reply client operation due to this change.
3233 * Changed all ID's in commands and in command replys as ID Payloads.
3234 Change affected both client and server side codes.
3236 All ID's sent in SILC network (with execption of ID's in SILC
3237 Packet header) are sent in ID Payload to support variable length
3240 * Server now notifies nick changes and notifies all clients on
3241 the channels about the new nickname (about the new Client ID,
3244 * Implemented CMODE command to change channel modes. Supports all
3245 channel modes defined by the protocol specs except ban and invite
3246 lists. (Also, private channel key mode is supported but support for
3247 setting private channel key in client is missing, thus, this mode
3248 has no effect on client side (except that server requires that the
3249 client uses private channel key and normal channel traffic does not
3252 Also, invite mode works per se, but INVITE command does not work
3253 yet correctly, so you can set channel as invite only channel but
3254 inviting clients to the channel does not work (it is yet to be
3255 thought what's the best way to do it).
3257 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3258 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3259 Implemented CUMODE command to change user's mode on the channel.
3260 Supports all modes defined by the protocol specs.
3262 * Added NAMES command reply to return users modes on the channel.
3264 * Removed unnecessary and slow ciphers from lib/silccrypt.
3266 * Set SO_KEEPALIVE option to connection sockets by default.
3268 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3270 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3271 redefined the Notify Payload into protocol specs.
3273 * Added silc_id_payload_parse_id to get ID directly from raw
3276 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3278 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3279 accept searching by Client ID as well.
3281 * Added support for LEAVE and SIGNOFF notify types in client library.
3283 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3284 to parse ID Payload from raw data.
3286 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3288 * Added flags parameter into silc_ske_assemble_security_properties
3289 function in lib/silcske/silcske.[ch].
3291 * Changed notify client operation to fit better for notify messages
3292 sent by server. The notify payload received from server is now
3293 passed to the application (after parsing it to SilcNotifyPayload).
3294 It is application's responsibility to retrieve the arguments
3295 from the payload and show the message the way it wants. The message
3296 sent by server is implementation specific.
3298 * Changed public keys to comply with the protocol specification.
3299 Old public keys are not supported anymore and are not compatible.
3301 * Removed nickname from Channel Payload as the latest draft removed
3302 it. The client must resolve the nickname from the NAMES command
3303 reply received when it joined the channel.
3305 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3307 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Fixed some errors in protocol specification drafts.
3311 * Created lib/silccore/silcnotify.c to implement Notify Payload
3312 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3313 generic payloads described by protocol specifications. The file
3314 includes implementations for ID Payload and Argument Payload.
3316 * Changed Command Payload implementation to use the new Argument
3317 Payload. Changed command_xxxx_payload to command_payload_xxxx
3318 to comply with SILC coding conventions.
3320 * Added suppport for Argument Payload handling in Notify Payload
3321 implementation as protocol requires it. Added the new support
3322 into server and client lib as well.
3324 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Added support for multiple nicknames on same channel. [n] is
3327 added locally to the nickname if there are more than one same
3328 nicknames on the channel.
3330 * Server now sends all nicknames that matched WHOIS request.
3331 Client also shows the list received from server.
3333 * Added TOPIC command to client side. User can now set and show
3334 current topic on channel.
3336 * Added MOTD command to client and server. Also, server sends the
3337 motd when client connects to the server.
3339 * Changed version strings to comply ISO 8601.
3341 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3343 * Fixed protocol error handling in client library. It should now
3344 cope even if the SKE fails for some reason.
3346 * Made new protocol specification drafts for submitting to IETF.
3348 * Implemented TOPIC command to server in silcd/command.c.
3350 * Added two new notify types into lib/silccore/silcnotify.h:
3351 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3352 notify nickname change and topic setting/change on a channel.
3354 * API change of command_reply operation in client library. The
3355 application gets now the status type received from server as well.
3357 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3361 * Cras fixed and optimized the packet handling even further and
3362 it should work now. Minor change to the prototype of function
3363 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3365 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Added new function into lib/silcutil/silcschedule.[ch]:
3368 silc_schedule_with_fd to select() a specified fd. The function
3369 returns after timeout expires or data arrives or goes. The
3370 function is used by packet routines to wait that all data is
3371 received from network.
3373 * Fixed data reading from network in lib/silccore/silcpacket.c.
3374 The code now assures that all data is read from the fd and then
3375 continues packet processing. This was a bug fix since the code
3376 used to drop some data in some circumstances.
3378 * Added new function into lib/silcclient/client.[ch]:
3379 silc_client_start_key_exchange to start key exchange after
3380 connection has been established to server. The code internally
3381 now uses this funtion but its main purpose was to provide it
3382 for applications that perform their own connecting. After
3383 application has created a connection it merely calls this
3384 function to start the key exchange between client and server.
3385 The library takes care of everything else after that.
3387 Updated also lib/silcclient/README to explain the usage of
3390 * Do not send to application information that connection has
3391 been established. Application gets notified it by connect
3394 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3396 * Applied cras's patch to add silc_schedule_one function. The
3397 function runs scheduler once and returns.
3399 * Fixed the scheduler after cras messed it up. The timeout
3400 handling works now as it's supposed to work.
3402 * Added into lib/silccore/ silcnotify.h to include notify
3403 message types support. Changed silc_server_send_notify*
3404 functions, in server.[ch], to support those new notify types.
3405 Added the support for the notify types into client library,
3406 as well. Added new notify client operation into ops.h in
3409 * Changed silc_server_packet_send_to_channel to send normal
3410 packets instead of just channel message packets. The function
3411 is now used to send the notify packets to channels. It is not
3412 used to send channel message packets anymore, as server never
3415 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3416 va_arg()s as it seems to require it nowadays. I guess, if SILC
3417 is compiled with older va_arg() the new code should work anyway.
3419 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Splitted core library. Core library (lib/silccore) includes
3422 now only SILC protocol specific core (and common) components.
3423 Created new utility library (lib/silcutil) that includes more
3424 generic purpose stuff. The stuff for util library was taken
3425 from the old core library. This was minor and easy split.
3427 * Created SILC Client Library (lib/silcclient) that includes
3428 implementation of the SILC client without user interface. This
3429 was major move from silc/ directory. The code has been changed
3430 so that it is transparent towards the user interface. The
3431 silc/ directory includes now the same user interface as before
3432 and it uses the new client library. Read lib/silcclient/README.
3433 Basicly, the client library performs everything else related
3434 to SILC except user interface handling. Also, configuration
3435 files are considered to be part of user interface and library
3436 does not handle them.
3438 This change also changed a lot of structures, function naming etc.
3439 Most important change was that SilcClientWindow object was
3440 renamed to SilcClientConnection in the client library. Created
3441 also new file lib/silcclient/ops.h. Also added new files
3442 silc/local_command.[ch] and silc/client_ops.[ch].
3444 All these changes were made to make it easier for user interface
3445 designers to create what ever user interface for the SILC client
3448 It is also expected that the server will be moved to lib
3449 directory as well and SILC Server Library will be created;
3450 sometimes in the future.
3452 * Removed Local commands from lib/silccore/silccommand.h as
3453 they are application specific and new client library does not
3454 handle any of those anymore.
3456 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3457 old client implementation in silc/.
3459 * Added support for callback functions in SILC_LOG_* macros.
3460 Application can now set its own callbacks that will be called
3461 instead of using the default functions that will always print
3462 the debug messages to stderr (or stdout). Also, debugging can
3463 now be disabled by setting silc_debug to FALSE and re-enabled by
3464 setting it to TRUE. Note, that logging will still work even
3465 if debugging is disabled.
3467 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3468 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3469 silc_log_reset_debug_callbacks.
3471 * To enable debugging in silc client one must give now -d
3472 option on command line.
3474 * Changed silc_schedule_init to automatically allocate task queues
3475 if they are not allocated before calling it.
3477 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Added GMP 3.1 into math library.
3481 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3484 a channel in SILC network. The packet is used by servers and
3485 routers to notify other routers that user has left a channel.
3486 This little feature was missing until now. Added the feature
3487 to protocol specification as well.
3489 Added functions: silc_server_send_remove_channel_user and
3490 silc_server_remove_channel_user into server.[ch].
3492 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3493 lib/silccore/silcpacket.h. However, they are not implemented
3496 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3498 * Fixed joining to a channel and sending channel messages
3499 between server and router. The channel message sending should
3500 now work inside a cell.
3502 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Fixed the private message sending between server and router.
3505 The private message sending should now work inside a cell.
3507 * Added silc_server_replace_id into server.[ch] to replace
3508 existing ID in the SILC network.
3510 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3511 and silc_idlist_replace_server_id into idlist.[ch] in server.
3513 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3515 * Fixed the server to server connections. Server can again now
3516 connect to router. Router to router connections probably does
3519 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Added dynamic protocol registering support. Now protocols can
3522 registered and unregistered on the fly. Patch by cras.
3524 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Added lib/contrib directory to hold routines that some platforms
3527 don't have but are needed by SILC.
3529 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3530 into lin/contrib to provide getopt() and getopt_long() for
3531 those who don't have it.
3533 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Added AWAY command to client. When away message is set and
3536 client receives a private message packet the client automatically
3537 replies to the sender with the away message.
3539 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3540 bug seemed to be the cause of recent problems when compiling
3543 * Added version detection support to SKE protocol specification
3544 and added the new changes to the SKE implementation as well.
3545 There were other minor changes in the SKE protocol as well.
3547 Many changes in lib/silcske/silcske.[ch] and in
3548 lib/silcske/payload.[ch].
3550 * Added ^U functionality, clear input line. Patch from cras.
3552 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3554 * Mainly small bugfixes on core library. Fixed some debugging
3555 logging and buffer overflow in silclog.c.
3557 * Updated config.sub and config.guess on the distribution tree.
3559 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * Added command lagging support in server. Client may execute
3562 commands now only once in two seconds.
3564 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Optimized packet reception. MAC computation and checking is now
3567 also more optimized. A lot previously duplicated code is now
3568 used as generic by both client and server.
3570 * Fixed key pair generation in clientutil.c
3572 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Added into lib/silccore/silcbufutil.[ch] new function;
3575 silc_buffer_realloc.
3577 * Moved generic packet sending/encryption functions to
3578 lib/silccore/silcpacket.[ch] from client and server. Some
3579 rewriting of the functions.
3581 * Moved all generic packet reception/decryption functions to
3582 lib/silccore/silcpacket.[ch] from client and server. The
3583 packet processing is now much cleaner in both client and server.
3584 These were major changes in both client and server.
3586 * Created many common functions in server to do packet sending.
3587 Previously code were duplicated a lot, this has been removed
3590 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Rewrote major parts of the ID cache system. Don't know
3593 whether it is better now or not but at least the API is more
3596 * Major rewrite on ID cache stuff on client because of the ID
3597 cache API changes. Added idlist.c to client.
3599 * Also major rewrite on ID cache stuff on server as well.
3600 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3601 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3602 in hand, instead they are all put into the ID cache system now.
3603 All server_idlist_* routines uses ID cache now instead of
3604 traversing its own lists (those lists does not exist anymore).
3605 SilcIDList though still exists. Also, SilcXXXEntry's are
3608 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Finally made the SKE implementation compliant to the protocol
3611 specification. All mp integers are now binary encoded as
3612 opposed being HEX encoded.
3614 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3617 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3618 functions: silc_[encode/decode]_pem. Also added function
3619 silc_encode_pem_file to PEM encode with newlines ('\n') for
3622 * SILC public keys are now encoded either PEM or binary. Same
3623 option is for private keys as well. By default private keys
3624 are binary encoded and public keys PEM encoded. Silly HEX
3625 encoding were removed.
3627 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3628 function to create fingerprints.
3630 * Fixed a bug in SHA1; does not change the original data anymore.
3632 * Partly implemented INFO command on client and server side.
3633 Fixed CLEAR command. Changes to SERVER command; show current
3634 server(s) when giving command without arguments. Added
3635 VERSION command to client.
3637 * Added check to server that unregistered connections cannot
3638 execute commands (unless it is specificly allowed).
3640 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Fixed screen refresh.
3644 * Fixed channel joining bug from client. On some circumstances
3645 client tried to join to a channel it had already joined.
3647 * Added public key verification process into client's protocol.c.
3648 The client now verifies the public key from user and saves
3649 it into ~./silc/serverkeys/ directory.
3651 Added into: clientutil.[ch]: silc_client_verify_server_key.
3653 * Changed SKE protocol's silc_ske_initiator_finish function
3654 to accept callback function that verifies the received public
3655 key. Removed old silc_ske_verify_public_key function.
3657 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3660 silc_pkcs_private_key[_data]_set.
3662 * Made the password and public authentication more cleaner in
3663 server's protocol.c.
3665 * Removed historic and obsolete protocol `channel_auth' from
3666 both client and server.
3668 * Removed wrong way of sending command status messages from
3669 server to client in server's command.c. The old way violated
3670 protocol specification.
3672 Changes to silccore/silccommand.[ch]: removed
3673 silc_command_encode_status_payload -> not needed anymore,
3674 changed silc_command_encode_payload_va to accept extra
3675 argument on variable argument list. The argument type must
3676 now be provided to the function. Also, added new function:
3677 silc_command_encode_reply_payload_va which is same as
3678 normal command_encode_payload_va except command status type
3679 is provided as extra argument.
3681 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Added ~./silc directory handling. The directory includes the
3684 public and private keys for the client.
3686 Added silc_client_check_silc_dir, silc_client_create_identifier
3687 and silc_client_load_keys.
3689 * Implemented SILC protocol compliant public key. Added public
3690 and private key saving to and loading from files.
3692 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3693 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3694 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3695 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3696 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3698 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3699 silc_pkcs_load_[public/private]_key.
3701 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3703 * Added silc_server_get_route (route.[ch]) to get connection
3704 data for the fastest route for given ID.
3706 * Implemented INVITE command on client and server. The command
3707 were re-defined in the SILC Protocol Specification and the
3708 implementation now complies with the specification.
3710 * Implemented PING command on client and server.
3712 * Implemented NAMES command on client and server. The server side
3713 supports currently only normal server not router server yet.
3714 Some changes to NAMES definition in SILC protocol specification.
3716 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Implemented LEAVE command on client and server.
3720 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3721 again. This change was made to the protocol as well. Server
3722 should not violate the protocol specification anymore.
3724 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3727 was tested. SOCKS4 was not but should work anyway.
