3 * Removed the `data' and `data_len' arguments from the ID Cache
4 interfaces and added `name' argument. ID Cache does not handle
5 anymore the binary data only a names associated with given ID.
7 * When hashing a Client ID with silc_hash_id the entire ID is
8 not hashed anymore, instead only the hash of the Client ID is
9 hashed. This way we can access the Client ID from the cache
10 with Client ID but with the hash of the ID (which is a hash of
11 the nickname) as well without any difference in performance.
13 Added also silc_idcache_find_by_id_one_ext to do one on one
14 searching when we have the actual ID. Added also function
15 silc_hash_client_id_compare. The affected files are
16 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
18 * When hashing the name associated with a ID it is always done
19 in lowercase. This way we can access the cache without worrying
20 about case-sensitivity, even though, for example nicknames are
23 * Fixed a bug in server with channel message sending. It put
24 wrong ID type as destination ID. The affected file
27 * silc_idcache_del_by_context now deletes from all hash tables
28 by context. Affected file lib/silccore/idcache.c.
30 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
32 * Changed the client library to use the new ID Cache interface.
33 Changes around the source tree.
35 * Added silc_hash_table_rehash_ext to rehash with specific
36 hash function. Affected file lib/silcutil/silchashtable.[ch].
38 * Added silc_hash_string_compare to compare two strings in the
39 hash table. Affected file lib/silcutil/silcutil.[ch].
41 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
43 * Added new function silc_idcache_del_by_context into the
44 lib/silccore/idcache.[ch].
46 * Changed the server's ID list routines to use the new ID Cache
47 interface. Changes around the source tree.
49 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
51 * Added silc_hash_table_del[_by_context]_ext functions in to the
52 lib/silcutil/silchashtable.[ch].
54 Removed silc_hash_table_find_all* routines and added new
55 silc_hash_table_find_foreach to replace them.
57 Added silc_hash_table_replace_ext function as extended
58 replacing function. Separated the simple hash table interface
59 from the extended hash table interface in the file
60 lib/silcutil/silchashtable.h.
62 * Fixed minor bugs and changed it to use some of the new
63 hash table functions in lib/silccore/idcache.c
65 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
67 * Added new function silc_hash_table_find_all to return all keys
68 in the hash table by the specified key. As the hash table is
69 collision resistant it also makes it possible to have several
70 duplicate keys in the hash table. This function may be used to
71 find all of the keys from the hash.
73 Added user_context arguments to the SilcHashFunction,
74 SilcHashCompare and SilcHashDestructor to deliver user specified
77 Added new fuctions silc_hash_table_find[_all]_ext to do
78 extended lookup with specified hash and compare functions and
79 specified user contexts.
81 Added new function silc_hash_table_add_ext to add the key
82 with specified hash function and user context.
84 Added new function silc_hash_table_foreach to traverse all
85 entrys in the hash table. Added SilcHashForeach callback
88 Added new function silc_hash_table_del_by_context to delete
89 the entry only if the context associated with the key matches.
91 Affected files are lib/silcutil/silchashtable.[ch].
93 * Removed silc_hash_[server/client/channel]_id and added just
94 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
95 silc_hash_id_compare to compare two ID's using as the hash table
96 comparison function. Added also silc_hash_data to hash
97 binary data and silc_hash_data_compare to compare it.
99 * Removed silc_idlist_find_client_by_hash as it is not needed
100 anymore. Affected file silcd/idlist.[ch].
102 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
103 to use internally the SilcHashTable. The new ID Cache is a lot
104 faster than the old one. Some of the ID Cache interface was also
105 rewritten and obsolete and stupid functions were removed.
107 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Added entry_count field to the SilcHashTable to keep the number
110 of the entries in the table. Implemented the function
111 silc_hash_table_rehash. Added new function
112 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
114 Fixed a minor bug in silc_hash_table_free.
116 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
117 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
118 into the lib/silcutil/silcutil.[ch].
120 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
122 * Implemented a collision resistant hash table into the
123 lib/silcutil/silchashtable[ch]. See the header and the source
124 for the SilcHashTable API.
126 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
128 * Merged dotconf version 1.0.2 into lib/dotconf.
130 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
132 * Do not compile anything in lib/silcsim/* if the SIM support
133 is not enabled. The tree should now compile without problems
136 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
138 * Compiled the SILC under cygwin. Compiled and tested briefly
139 without problems. More tests needed. The SIMs didn't compile
142 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
144 * Fixed possible crash in silc_get_username in the
145 lib/silcutil/silcutil.c.
147 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
149 * Fixed a va_arg in silc/client_ops.c.
151 * Oops, RC5 routines were named AES and caused some problems
152 when not using SIM's. Affected file lib/silccrypt/rc5.c.
154 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
156 * Added new SilcIDIP structure into the lib/silccore/id.h and
157 replaced the old `ip' fields from all SILC ID's to that type.
158 This is a step towards IPv6 support.
160 The silc_id_get_len takes now the ID as an extra argument.
161 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
162 both IPv4 and IPv6 based ID's.
164 The affected files are lib/silccore/id.[ch] and other files
165 around the tree using these routines.
167 * Removed the ID length arguments in server from various
168 silc_server_send_notify_* routines -> they are not needed
171 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
173 * Fixed memory leak in silc_encode_pem_file in the file
174 lib/silcutil/silcutil.c.
176 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
178 * Check minor version as well in the SKE. Affected files are
179 silcd/protocol.c and lib/silcclient/protocol.c.
181 * Added --identifier option to the server so that an identifier
182 can be when creating the public key for the server. Affected
183 file is silcd/silcd.c.
185 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
186 lib/silccrypt/silcpkcs.c.
188 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
190 * Register default ciphers and stuff when using -C option with
191 the server. Affected file sildc/silcd.c.
193 * Put back the servers public key filename format, it is better
194 than the new one. For now, the client keys are saved with the
195 new filename format. The affected file silc/client_ops.c.
197 * Implemented the Cipher API for the rest of the ciphers that
198 did not implement it or implemented it the wrong way.
200 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
202 * Register default ciphers and stuff when using the -S option
203 in the client. Affected file silc/silc.c. Same also when
204 creating new key pair with -C option.
206 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Fixed the silc_verify_public_key client operation function to
209 save the public keys differently. The fingerprint is now
210 used as filename and not the hostname. This way also the
211 client keys are saved uniquely and not with hostnames. The
212 affected file is silc/client_ops.c.
214 * Trimmed the silc_hash_fingerprint function to remove extra
215 whitespaces from the end of the fingerprint. The affected
216 file is lib/silccrypt/silchash.c.
220 * Added silc_cipher_register_default function to register all
221 default ciphers. It can be used when configuration files
222 does not exist and the application does not want any specific
223 ciphers in any specific order.
225 The SilcDList is now used as silc_cipher_list dynamically
226 allocated cipher list. Removed the static list all together
227 and now all ciphers must be allocated to the dynamic list.
228 The silc_cipher_alloc routine was changed to check only the
231 All silc_cipher_* routines that used to return int returns
234 The affected files lib/silccrypt/silccrypt.[ch].
236 * The same thing was done to silc_hash_* as for silc_cipher_*
237 routines. Affected files lib/silccrypt/silchash.[ch].
239 * The same thing was done to silc_pkcs_* as for silc_cipher_*
240 routines. Affected files lib/silccrypt/silcpkcs.[ch].
241 Added also silc_pkcs_[un]register[_default] functions.
242 Removed the data_context from the PKCS API.
244 * Added silc_hmac_register_default function to register default
245 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
246 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
247 to unregister all hmacs at once.
249 * Register the default ciphers, hash functions, PKCSs and HMACs
250 if client's configuration file does not exist. The affected
253 * The client did not load the hash functions from the SIM
254 modules at all. Added support for this. Affected file is
257 * When decoding public key with silc_pkcs_public_key_decode, check
258 the supported algorithm only if PKCS are registered. Affected
259 file lib/silccrypt/silcpkcs.c. The same was done with the
260 silc_pkcs_private_key_decode.
262 * Fixed the SILC List routines to keep the list always in order.
263 It used to change the list's order when traversing the list but
264 not it preserves the order. Affected file lib/trq/silclist.h.
266 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
268 * Added the client library to use the SilcSocketConnection's
269 reference counter (by silc_socket_dup) to prevent the bug that
270 the socket object may be freed underneath async operation.
272 * The name resolv library checking fixes in the configure.in.pre.
275 * Created new version of the protocol drafts for future
276 development. The -03 drafts are the ones that will be changed
277 in the trunk now and the -02 will remain as they are.
279 * Send list of CUMODE notifys to the router when announcing
280 the channel users to the router. Affected file silcd/server.c.
281 If the router receiving channel founder CUMODE for a channel
282 that already has channel founder it will send CUMODE notify
283 to the sender to remove the channel founder rights from the
284 announced client. Affected file silcd/packet_receive.c.
286 * The CUMODE notify may now use Server ID as well as the entity
287 who changes the mode. Updated protocool specs.
289 * Updated INSTALL and README files.
291 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
293 * New web pages in the http://silc.pspt.fi. The pages was
298 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
300 * Implemented the [DenyConnectin] config section in the server.
301 Added silc_server_config_denied_conn to check whether incoming
302 connection is denied. Affected file silcd/serverconfig.[ch].
304 * Do not check the ports when checking the incoming configuration
305 data if the port is 0, meaning any. Affected file is
306 silcd/serverconfig.c.
308 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
310 * Fixed buffer overflow in silc_string_compare in the file
311 lib/silcutil/silcutil.c.
313 * Fixed double free in silc_server_command_leave in the file
316 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * Fixed the version checking in the server. Affected file is
321 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
323 * Fixed the configuration data fetching when accepting new
324 connections in the server. Affected file silcd/server.c.
326 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
328 * Added `sender_entry' argument to the function
329 silc_server_packet_relay_to_channel so that we can check
330 whether some destination actually belongs to the same route
331 the sender belongs (ie, we must not resend the packet to the
332 sender). Affected file silcd/packet_send.[ch].
334 * Added `servername' field to the SilcClientEntry in the server
335 to hold the name of the server where client is from. Affected
336 file is silcd/idlist.h.
338 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
340 * Moved the channel message encrypting in the router betwen
341 router connections from silc_server_channel_message to the
342 silc_server_packet_relay_to_channel since we want to check
343 whether we have anybody channel before encrypting anything.
344 Affected files silcd/packet_[receive/send].c.
346 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * Fixed the [AdminConnection] server config section to support
349 multiple entries. Affected file silcd/serverconfig.c.
351 * Added support into the server to check the validity of the
352 incoming connection before executing any KE or authentication
355 * The connection configuration is now saved to the KE and
356 connection auth protocol contexts and not fetched anymore in
357 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
359 * The local hosts listenning address and port is also resolved
360 now when starting the server. We want to have the socket object
361 to include the real address and port for the listener. Added
362 new function silc_net_check_local_by_sock into the files
363 lib/silcutil/silcnet.[ch].
365 * Fixed a broadcast bug in server -> do not broadcast if we
368 * Fixed a routing bug. Do not route broadcast packets ever.
369 Broadcast packets must be processed always and not routed since
370 they may be destined to some other host than yourself and thus
371 would get routed without no good reason. Affected file is
374 * Added function silc_server_config_is_primary_route to check
375 whether primary router connection has been configured (a router
376 configuration that we are initiating). If there is not, we
377 will assume that there is only two routers in the SILC network
378 and we will use the incoming router connection as our primary
379 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
381 * Changed the order of the broadcasting. Broadcast _after_ the
382 packet has been processed not before. Affected file is
385 * Fixed a [ClientConnection] parsing bug. The port was never
386 parsed correctly thus resulting to port 0. Affected file
387 silcd/serverconfig.c.
389 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
390 argument and did not set the broadcast packet flag. Affected
391 file silcd/packet_send.c. Fixed same bug in the function
392 silc_server_send_notify as well.
394 * If we receive NEW_ID packet for our own ID in the server, ignore
397 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
401 * Removed the nickname from the Private Message Payload.
402 Updated the code and the protocol specs.
404 * Updated protocol specs for submitting to the IETF.
406 * Tweaked the Random Number Generator a bit. Affected file
407 lib/silccrypt/silcrng.c. Exported a new function
408 silc_rng_[global]_add_noise which can be used to add more
411 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
413 * Do not parse packets with different timeout when protocol
414 is active -> may cause problem with rekey. Affected file
417 * When server receives signoff notify it must not create
418 new channel key if the client is on any channels since the
419 sender of the signoff notify will create it.
421 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
423 * Added printing of error messages during SKE protocol from the
424 failure packet sent by server during SKE. Affected file
427 * Removed the client's failure_callback handling with timeout
428 and handle it immediately when received.
430 * The SKE library returned wrong type in SUCCESS and FAILURE
431 packets. They must be 32 bit MSB not 16 bit MSB.
433 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
435 * Ok, rewrote the logic of the re-key and now it seems to work.
436 I tested it on high traffic with frequent re-keys without
437 problems. Added hmac_receive (and renamed hmac to hmac_send)
438 in SilcClientConnection in lib/silcclient/client.h and
439 in SilcIDListData in silcd/idlist.h. Also, removed the
440 SilcPacketParserContext's cipher and hmac fields as they are
441 not needed anymore and actually caused some problems when
442 the ciphers and hmac's changed underneath the packet parser.
444 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
446 * If re-key protocol is active then process the incoming packets
447 synchronously since we must assure that icoming packets encrypted
448 with the old key is processed before the new keys is set to
449 use. This is true other packets than for REKEY packets.
450 Affected file silcd/server.c. The same was done to client library
451 as well, affected file lib/silcclient/client.c.
453 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
455 * Fixed bug in client and server to accept the force send if
456 the packet is send from silc_[server/client]_packet_process
457 function. Otherwise the packets are never delivered, oops.
459 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
461 * Disable force sending of packets when REKEY protocol is active.
462 We must assure that no packet is sent directly when rekey is
463 performed. All packets must be sent through packet queue.
464 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
465 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
466 function is silc_[server/client]_packet_send_real to check
469 * Replaced the SIM paths from example config files to
470 /usr/local/modules. Also, make install creates now
471 /usr/local/silc/logs directory to hold all the SILC server
474 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
476 * Made the configure.in.pre work on Solaris. Patch by salo.
478 * Made all ciphers compatible with non-x86 machines. Defined
479 CBC mode macros into lib/silccrypt/ciphers_def.h.
481 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
483 * Fixed the make install.
485 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
487 * When MAC computation fails the silc_packet_decrypt returned 0
488 even though it was supposed to return -1. Fixed this. The
489 affected file is lib/silccore/silcpacket.c.
491 * Do not replace the config files in /etc/silc (in make install)
492 if they already exist. Affected file ./Makefile.am.
494 * Do not send re-key packets immediately but through packet queue.
495 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
497 * Changed silc_net_check_host_by_sock to return FALSE if the
498 IP/DNS could not be resolved. Though, it returns the IP address
499 now even if it could not resolve it (but returns also FALSE).
500 Affected file lib/silcutil/silcnet.[ch].
502 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
504 * Added silc_pkcs_decode_identifier to decode the public key's
505 identifier. Affected file lib/silccrypt/silpkcs.[ch].
506 Added also silc_pkcs_free_identifier. Added also new context
507 SilcPublicKeyIdentifier.
509 * Added -S option to the silc client. It is used to dump the
510 contents of the specified public key file.
512 * Changed the PKCS api to return the public key length when
513 setting the public key.
515 * Fixed a fatal bug in the public and private key file loading.
516 Affected file lib/silccrypt/silcpkcs.c.
518 * Execute the packet parsing for client with zero (0) timeout
519 if the protocol is active. Affected file silcd/server.c.
521 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
523 * Made the key generation options to the silcd program. Added
524 -C option, equivalent to client's option.
526 * Added new [ServerKeys] config section to the server. It
527 configures the server's public and private key.
529 * Defined generic Public Key Payload into the protocol
530 specification to send specific type of public keys and
533 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
534 public key or certificate.
536 * Implemented the GETKEY command to the server and to the
537 client library and on user interface.
539 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
541 * Made preliminary `make install' work.
543 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
545 * Added SilcServerRekey context into silcd/idlist.h.
547 * Added the PFS support as defined in the specification to the
548 SKE protocol. Affected files lib/silcske/*.c.
550 * Added `ske_group' field to the SilcServerRekey context to hold
551 the number of the SKE group that is used with PFS in re-key.
552 Affected file silcd/idlist.h.
554 * Added PFS re-key support to the server. Affected file is
557 * Added silc_protocol_cancel to cancel execution of the next
558 state of the protocol. Affected file is
559 lib/silccore/silcprotocol.[ch].
561 * Added the re-key support with and without PFS to the client
562 library. Re-key is performed once in an hour, by default.
564 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
565 Added silc_client_rekey_callback and silc_client_rekey_final.
566 Affected files are lib/silcclient/protocol.[ch] and
567 lib/silcclient/client.[ch].
569 * Removed the `hmac_key' and `hmac_key_len' fields from the
570 SilcClientConnection structure; not needed. Affected file is
571 lib/silcclient/client.h.
575 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
577 * Do not ask whether user wants to use the negotiated private key
578 for private messages, just use it. Affected file is
579 silc/local_command.c.
581 * Added `send_enc_key' and `enc_key_len' fields to the
582 SilcIDListData structure since they are needed in the re-key
583 phase. Affected file is silcd/idlist.[ch].
585 * Implemented the simple re-key protocol into the server.
586 Affected files silcd/server.c and silcd/protocol.[ch]. The
587 re-key will be performed once in an hour, by default.
589 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
590 Added silc_server_rekey, silc_server_rekey_callback and
591 silc_server_rekey_final.
593 * Removed Tunneled flag from the protocol. Updated the code
594 and the specifications.
596 * Adde `pfs' field to the SilcIDListData to indicate whether
597 the PFS is to be performed in the re-key. Affected file is
600 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
602 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
603 int64 of at least the xintXX size. If void * is less that 4
604 bytes uint32 * will be used. Defined bool as boolean.
606 * Changed _ALL_ unsigned long and unsigned int to uint32,
607 unsgined short to uint16 in the source tree.
609 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
610 not handle clients that has entry->data.registered == FALSE.
611 They are not in the network anymore. Affected file is
614 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
616 * Implemented the sending of the SERVER_SIGNOFF notify in the
617 server. Affected file is silcd/server.c.
619 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
620 Added also silc_notify_payload_encode_args into the
621 lib/silccore/silcnotify.[ch].
623 * Implemented ther SERVER_SIGNOFF notify handling in the server.
624 Affected file silcd/packet_receive.c.
626 * Implemented the SERVER_SIGNOFF notify handling in the client
627 library. Affected file lib/silcclient/client_notify.c. Also,
628 implemnted the printing of the SERVER_SIGNOFF info to the
629 application. Affected file silc/client_ops.c.
631 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
632 if the deleting was successful. Affected file silcd/idlist.[ch].
634 * Added support for public key authentication in the connection
635 authentication protocol in the client library. Affected file
636 lib/silcclient/protocol.c.
638 * Changed the server's silc_idlist_get_clients_by_* interface
639 to support already allocated array so that new entries may be
640 added to pre-allocated array. Affected file silcd/idlist.[ch].
641 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
644 * All command reply functions in the server now calls the
645 pending command callback even if error occured. This way the
646 error will be delivered to the client as well. Affected files
647 silcd/command.c and silcd/command_reply.c.
649 * Fixed INFO command to return local server's info if no server
650 was provided. Affected file lib/silcclient/command.c.
652 * Removed RESTART command for good. Updated the code and the
655 * Rewrote parts of the task system. It is a bit simpler now.
656 Removed unsued task priorities. The affected files are
657 lib/silcutil/silctask.[ch].
659 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
661 * Moved the USERS printing from the library to the application.
662 Affected files lib/silcclient/command.c and silc/client_ops.c.
664 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
668 * Added channel key re-key support. The re-key is perfomed
669 only by the router and is done once in an hour. Added `rekey'
670 field to the SilcChannelEntry in the server. Affected files
671 silcd/server.c and silcd/idlist.h.
673 * Added silc_task_unregister_by_context into the file
674 lib/silcutil/silctask.[ch].
676 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
678 * Added SILC_UMODE_GONE mode to indicate when the client is not
679 present in the SILC network. Added also support to the local
680 command AWAY that will set this mode. Added support of showing
681 "xxx is gone" in WHOIS command. The USERS command shows the
684 * Fixed setting server and router operator privileges in the
685 server's UMODE command. Affected file silcd/command.c.
687 * Merged the SKE KE1 and KE2 payloads into one payload. The
688 new KE payload is equivalent to the old KE2 payload.
690 Cleaned up the SKE Start Payload parsing. It now uses the
691 simple buffer unformatting to do the parsing. A lot faster
694 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
695 to the SKE that is used to indicate whether both of the SKE
696 parties should perform authentication. By default only the
697 responder performs authentication. By setting this flag also
698 the initiator must do authentication. By default it is unset
699 since in normal SKE case, client to server connection, only
700 the responder should do authentication. When doing SKE between
701 two clients both should perform authentication. Updated the
702 code and the protocol specs.
704 * A little fix to IDENTIFY command in the server. Search the
705 client first by hash not nickname. Affected file is
708 * Fixed the silc_client_close_connection to support closing
709 the client to client connections wihtout deleting too much
710 data. Affected file lib/silcclient/client.c.
712 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
713 are received if protocol used to be active but is not anymore
714 the application would crash due to NULL pointer dereference.
715 Affected files silcd/server.c and lib/silcclient/client.c.
717 * Added `hash' field to the SilcClientConnection to include
718 the hash function negotiated in the SKE protocol.
720 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
721 to set the channel founder authentication data. A client can
722 claim the founder rights later by providing the authentication
723 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
724 This way the channel founder can regain the channel founder
725 privileges even it is left the channel. This works only on
726 local server and the client must be connected to the same
727 server to be able to regain the founder rights. Updated the
728 protocol specs accordingly.
730 Added support to the CMODE command in the client to set the
731 founder auth data. Read the README to see how to set it.
733 Added support to the CUMODE command to claim the founder
734 rights. Read the README to see how to do it.
736 Added support for the founder authentication to the Channel
737 Entry in the server. Affected file silcd/idlist.h.
739 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
740 server's CMODE command. Affected file silcd/command.c.
742 * Added the following new functions into lib/silccore/silcauth.[ch]:
743 silc_auth_get_method and silc_auth_get_data.
745 * The server now saves the remote hosts public key to the
746 SilcIDListData pointer. Affected file silcd/protocol.c.
748 * The normal server now does not remove the channel entry from
749 the cache if the founder authentication data is set. It used
750 to remove it if the founder was the last one on the channel on
751 the server and left the channel. The auth data is saved and
752 if the channel is re-joined later the old entry is used with
753 the old auth data. Affected files silcd/command_reply.c and
756 * Removed the `pkcs' field from the SilcIDListData structure
757 in the server; it is not used. Affected file silcd/idlist.h.
759 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Fixed packet processing on slow links. Partial packets were
762 never re-processed because the incoming data buffer was cleared
763 by the application. Application must not directly clear the
764 sock->inbuf, the packet processing routines handle it. Fixed
765 this in client library and in server.
767 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
769 * Fixed the WHOIS and IDENTIFY send reply function to really
770 check whether to send list or just one entry. Affected file
773 * Cleaned up the LEAVE command's channel key distribution. The
774 affected file silcd/command.c.
776 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
777 can enforce the channel mode as well. In that case the ID
778 includes the ID of the server. The code now enforces the
779 mode change if the router have different mode than the server.
781 * The notify client operation with CMODE_CHANGE notify can now
782 return NULL client_entry pointer if the CMODE was not changed
783 by client. Application must check for this.
785 * Added <Server ID> argument to INFO command to support server
786 info fetching by Server ID.
788 * Added silc_server_announce_get_channel_users to get assembled
789 packets of channel users of the specified channel. Affected
790 file silcd/server.[ch].
792 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
793 was freed underneath the ID Cache.
795 * Re-announce clients when the server received CHANNEL_CHANGE
796 notify from the router. Affected file silcd/packet_send.c.
798 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
800 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
801 crashed since it did not handle the fact that there is no cipher
802 called "3" and didn't check the error condition. Now fixed.
804 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
805 flag. It can be used to send message requests.
807 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * Implemented the RESTART command in the client.
811 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
812 notice type messages. Added notice printing to the user
815 * The channel keys are not re-generated if the channel's mode
816 is PRIVKEY, ie private key on the channel exists. Affected
817 files silcd/server.c and silcd/command.c.
819 * Fixed a little bug in channel message delivery when channel
820 private keys are set in the server. Affected file is
823 * Changed the setting on channel->on_channel = TRUE from the
824 silc_client_save_channel_key to the JOIN command reply. The
825 key payload is not received if the private channel key is set.
826 Affected file lib/silcclient/command_reply.c and the
827 lib/silcclient/client_channel.c.
829 * When the CMODE_CHANGE notify is sent and the channel private
830 key mode is removed the channel key must be re-generated in
831 other cells as well. Added this support for the router in the
832 silcd/packet_receive.c.
834 * Added new local command NOTICE to send notice message on
835 channel. Affected file silc/local_command.[ch].
837 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
839 * Added new local command ME to the client. It is used to send
840 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
841 some action. Affected file silc/local_command.[ch].
843 * Changed channel_message and private_message client operations
844 to deliver the message flags to the application. Added also
845 the `flags' arguments to the silc_client_send_channel_message
846 and silc_client_send_private_message functions. Affected file
849 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
851 * Redefined the Private Message Payload to support private message
852 keys and to support the new private message flags. Updated
853 the protocol specs. Flags makes it possible to have for example
856 * Added new type SilcPrivateMessagePayload and defined an API
857 for it in the lib/silcclient/silcprivate.[ch].
859 * Tested private message private keys successfully. Tested the
860 private message key set, unset and list commands with the new
863 * Redefined the Channel Message Payload to include the channel
864 message flags (equal with private message flags) to support
865 for example CTCP style messages.
867 * Defined some of the message (for channel and private message)
868 flags. Updated the protocol specs and added the flags to the
869 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
871 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
873 * Added SilcKeyAgreementStatus type to the key agreement routines
874 to indicate the current status and error if one occured.
875 The status types are defined in the lib/silcclient/silcapi.h.
877 * Added new local command KEY that is used to set and unset private
878 keys for channels, set and unset private keys for private messages
879 with remote clients and to send key agreement requests and
880 negotiate the key agreement protocol with remote client. The
881 key agreement is supported only to negotiate private message keys,
882 it currently cannot be used to negotiate private keys for channels,
883 as it is not convenient for that purpose.
885 * Fixed a minor pending callback setting bug in the function
886 silc_client_get_client_by_id_resolve, now the function works.
887 Affected file lib/silcclient/idlist.c.
889 * Added function silc_net_get_local_port to get local bound
890 port by socket. Added to lib/silcutil/silcnet.[ch].
892 * Added `sockets' and `sockets_count' fields to the SilcClient
893 object. They hold the sockets of the listenning sockets in
894 the client. Listenning sockets may be for example the key
895 agreement server. Affected file lib/silcclient/client.[ch].
896 Added functions the silc_client_add_socket and the
897 silc_client_del_socket. They are exported to the application
900 * Added ~./silc/clientkeys to support other client's public keys.
902 * Renamed verify_server_key client operation to verify_public_key
903 and added one argument to indicate the type of the connection
904 (server, client etc.).
906 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
908 * Added silc_server_connection_auth_request to handle the
909 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
910 silcd/packet_receive.[ch].
912 * Added silc_server_send_connection_auth_request into the
913 silcd/packet_send.c to send the connection auth request packet.
915 * Cleaned up the silcd/protocol.c a bit and fixed some memory
918 * Fixed the public key authentication in responder side in the
919 server. The `auth_data' pointer includes the SilcPublicKey
920 not the path to the public key. Affected file silcd/protocol.c.
922 * Implemented the public key authentication in the initiator side
923 in the server. Affected file silcd/protocol.c.
925 * Removed the [RedirectClient] config section from the server
926 configuration. Is not needed and I don't want to implement it.
928 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
930 * Cleaned up the CMODE command in the server. It now works
931 correctly and supports all the modes defined in the protocol.
932 Affected file is silcd/command.c.
934 * Added `hmac_name' field to the SilcChannelEntry in the server
935 to hold the default HMAC of the channel. It can be set when
936 creating the channel (with JOIN command). Affected files
939 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
940 type to indicate the change of the current cipher and hmac
941 on the channel. Client can safely ignore the <cipher> argument
942 (if it chooses to do so) since the CHANNEL_KEY packet will
943 force the channel key change anyway. The <hmac> argument is
944 important since the client is responsible of setting the new
945 HMAC and the hmac key into use.
947 * Fixed the CMODE command in the client library as well.
949 * Tested CMODE command in router environment successfully.
951 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
953 * Show the version of the remote client (or server) when connecting
954 to the server. It is logged to the log file. Affected file
957 * Fixed the KILLED notify handling in the client library. The
958 client must be removed from all channels when receiving the
961 Also, do not remove the client entry when giving the KILL
962 command but when the KILLED notify is received.
964 * Removed silc_idlist_find_client_by_nickname from the server.
965 Not needed anymore. Affected files silcd/idlist.[ch].
967 * Implemented the CHANNEL_CHANGE notify type handling to the
968 server. Affected file silcd/server.c.
972 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
974 * Added silc_server_send_notify_invite to send the INVITE
975 notify between routers.
977 * Implemented the INVITE command correctly to the server.
979 * Implemented the INVITE notify type handling in the server.
981 * Implemented the INVITE command to the client library and on the
984 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
986 * Added function silc_server_get_client_resolve to find the
987 client entry by ID from all ID lists and then resolve it
988 (using WHOIS) if it cannot be found. Affected file is
991 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Implemented the BAN command to the client library.
995 * The JOIN command in the server now checks the invite list
998 * Changed the silc_command_reply_payload_encode_va and the
999 silc_command_payload_encode_va to support that if argument is
1000 NULL it ignores and checks the next argument. Affected file
1001 lib/silccore/silccommand.c.
1003 * Added silc_server_send_notify_ban to send the BAN notify
1004 type between routers.
1006 * Chaned the silc_notify_payload_encode to support that if
1007 argument is NULL it ignores and checks the next argument.
1008 Affected file lib/silccore/silcnotify.c.
1010 * Tested ban lists in router environment successfully.
1012 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1014 * Implemented BAN command to the server, in silcd/command.[ch].
1016 * Removed the BAN and INVITE_LIST modes from the CMODE command
1019 * Added function silc_string_match to regex match two strings.
1020 Affected files lib/silcutil/silcutil.[ch].
1022 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1024 * Redefined parts of the SilcChannelEntry in the server to support
1025 the new ban and invite lists.
1027 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1029 * Redefined the INVITE command. The same command can be used to
1030 invite individuals to the channel but also to manage the invite
1031 list of the channel (to add to and remove from the invite list).
1032 Updated the protocol specs.
1034 * Added new command SILC_COMMAND_BAN that can be used to manage
1035 the ban list of the channel. Updated the protocol specs.
1037 * Removed the channel modes: the SILC_CMODE_BAN and the
1038 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1039 in the CMODE command. The equivalent features are now available
1040 using INVITE and BAN commands. Updated the protocol specs.
1042 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1043 in the network about change in the current ban list. The notify
1044 type is not used by the client.
1046 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1047 support the invite lists.
1049 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1051 * Added new function silc_string_regexify that converts string
1052 including wildcard characters into regex string that can
1053 be used by the GNU regex library. Added into the file
1054 lib/silcutil/silcutil.[ch].
1056 Added silc_string_regex_combine to combine to regex strings
1057 into one so that they can be used as one regex string by
1058 the GNU regex library. Added into the file
1059 lib/silcutil/silcutil.[ch].
1061 Added silc_string_regex_match to match two strings. It returns
1062 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1064 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1066 * Imported GNU regex to the soruce tree into lib/contrib.
1067 Fixed some compiler warning from the regex.c.
1069 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1071 * Fixed MOTD command in the server to work in router environment.
1073 * Fixed the MOTD command in the client library to support
1074 the server argument in the command.
1076 * Added `nickname_len' argument to the silc_idlist_add_client
1077 in the server, as the `nickname' argument may be binary data
1080 * Added silc_idlist_get_channels to return all channels from
1083 * Implemented LIST command to the server. Affected file is
1086 * Implemented the LIST command to the client library and on the
1089 * Added [<user count>] argument to the LIST command reply.
1090 With private channels the user count is not shown.
1092 * Updated TODO and README.
1094 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1096 * The client entry's data.registered must be TRUE even with
1097 global client entry on global client list. The data.registered
1098 is used to check whether the client is anymore in the network,
1099 for example with WHOWAS command so it must be valid.
1101 * Fixed the WHOWAS command in the server. It now actually works
1102 in router environment. Added function into silcd/command_reply.c
1103 silc_server_command_reply_whowas_save.
1105 * Added silc_idlist_purge function to the silcd/idlist.c
1106 to periodically purge the ID Cache.
1108 * Fixed INFO command in the server. It works now in router
1109 environment. Added <server name> argument to the INFO command
1110 reply. Updated the protocol specs.
1112 * Fixed minor bug in silc_idcache_purge to not purge if the
1113 expire value is zero.
1115 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1116 they were buggy because of the WHOWAS information.
1118 * Fixed local command MSG to handle the async resolving of
1119 the remote client properly. It used to fail the first MSG.
1120 Affected file silc/local_command.c.
1122 * Added `data_len' field to SilcIDCache context.
1124 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1126 * Update TODO. Todo in commands in the server.
1128 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1130 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1131 used by routers as broadcast packet to inform other routers
1132 about the changed user mode.
1134 Implemented the notify handling in the server. Affected file is
1135 silcd/packet_receive.c. Added the function
1136 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1138 * Added new generic Channel Payload and deprecated the New Channel
1139 Payload. The New Channel Payload is now the generic Channel
1142 * Added new argument `mode' to the silc_server_send_new_channel
1143 as it is required in the Channel Payload now.
1145 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1146 and created a new and real SilChannelPayload to represent the
1147 new generic Channel Payload. Implemented the encode/decode
1148 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1150 * Added silc_server_get_client_channel_list to return the list
1151 of channels the client has joined for WHOIS command reply.
1152 Affected file silcd/server.[ch].
1154 * Implemented the channel list sending in the WHOIS command reply
1155 in server and in the client.
1157 Implemented the channel list displaying on the user interface
1158 as well. Affected file silc/client_ops.c.
1160 * Added silc_channel_payload_parse_list to parse list of Channel
1161 Payloads. It returns SilcDList list of SilcChannelPayloads.
1162 Client for example can use this function to parse the list of
1163 channels it receives in the WHOIS command reply. The caller
1164 must free the list by calling silc_channel_payload_list_free.
1165 Affected files lib/silccore/silcchannel.[ch].
1167 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1169 * Added one new argument <user mode> to the WHOIS command reply
1170 to return the mode of the user in SILC. Updated the protocol
1173 Implemented it to the server and client.
1175 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1177 * Fixed the mode printing on the user interface on joining.
1178 Affected file silc/client_ops.c.
1180 * Implemented the UMODE command and user modes in general to the
1181 client library and to the user interface.
1183 * Implemented the UMODE command to the server.
1185 * The server now sends UNKNOWN_COMMAND error status if client sends
1186 unknown command. Affected file silcd/command.c.
1188 * All server commands now handle the command identifier the right
1189 way when sending the command reply to the client. The client can
1190 use to identify the command replies with the identifier.
1192 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1194 * Added silc_server_get_client_route to resolve the route to
1195 the client indicated by the client ID. Affected file is
1198 * Added silc_server_relay_packet as general function to relay
1199 packet to arbitrary destination. This deprecates functions
1200 like _send_private_message_key, _relay_notify etc. Affected
1201 file is silcd/packet_send.[ch].
1203 Removed silc_server_send_key_agreement,
1204 silc_server_send_private_message_key and
1205 silc_server_packet_relay_notify functions from the file
1206 silcd/packet_send.[ch].
1210 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1211 server. Affected file silcd/packet_receive.[ch].
1213 * Implemented the KILL command to the client. Implemented the
1214 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1215 Affected files lib/silcclient/command[_reply].c and
1216 lib/silcclient/client_notify.c. Implemented the KILL notify
1217 printing in the user inteface.
1219 * Fixed a lot silc_parse_nick memory leaks from the client
1220 library in the file lib/silcclient/command.c.
1222 * Changed the silc_server_send_notify_on_channels's `sender'
1223 argument from SilcSocketConnection to SilcClientEntry to
1224 check the sender as entry and not as connection object and not
1225 to send to the client provided as argument. The affected file
1226 is silcd/packet_send.[ch].
1228 * The notify packets that are destined directly to the client used
1229 to not to be processed by the server. Now changed that and the
1230 server processes all notify packets. After relaying the packet
1231 to the client the notify packet is processed in the server.
1233 * The silc_server_free_client_data now checks whether there is
1234 pending outgoing traffic for the client and purges the data to
1235 the network before removing the client entry.
1237 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1239 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1240 an client is killed from the SILC Network. Updated the protocol
1243 Added new function silc_server_send_notify_killed to the
1244 silcd/packet_send.[ch].
1246 * Added function silc_server_packet_relay_notify to relay notify
1247 packets that are destined directly to a client. In this case
1248 the server does not process the notify packets but merely relays
1249 it to the client. Affected file silcd/packet_send.[ch].
1251 Added also silc_server_packet_process_relay_notify to check
1252 whereto relay the notify. Affected file is
1253 silcd/packet_receive.[ch].
1255 * Implemented the KILL command to the server.
1259 * Added the backup schema desgined last fall to the protocol
1260 specs for everyone to see. The specification is in the
1261 *-spec-xx.txt draft and the packet type definitions for the
1262 backup routers is in *-pp-xx.txt draft. Thusly, added also
1263 new packet type SILC_PACKET_CELL_ROUTERS.
1265 * A big security problem in the implementation discovered. The
1266 signoff of an client did not cause new channel key generation
1267 which it of course should've done. The channel keys must be
1268 always re-generated when client leaves (or signoffs) the channel.
1269 The silc_server_remove_from_channels funtion now handles
1270 the channel key re-generation.
1272 * Added `sender' argument to the silc_server_send_notify_on_channels
1273 to not to send the client provided as argument. Affected file
1274 silcd/packet_send.[ch].
1276 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1278 * Implemented OPER and SILCOPER commands into the server and
1281 * Added silc_auth_verify and silc_auth_verify_data to verify
1282 the authentication directly from the authentication payload.
1283 It supports verifying both passphrase and public key based
1284 authentication. Affected file lib/silccore/silcauth.[ch].
1286 * Added `hash' field to the SilcIDListData structure. It is the
1287 hash negotiated in the SKE protocol. Affected file is
1290 * Slight redesigning of the SilcAuthPayload handling routines.
1291 Do not send SilcPKCS but SilcPublicKey as argument.
1293 * Implemented the public key authentication support to the
1294 serverconfig. The public key is loaded from the provided path
1295 and saved as authentication data to void * pointer. Thus,
1296 changed the unsigned char *auth_data to void *auth_data;
1298 * Fixed SHUTDOWN command to send the reply before the server
1299 is shutdown. :) Affected file silcd/command.c.
1301 * Fixed fatal bug in CONNECT command. The hostname was invalid
1302 memory and server crashed. Affected file silcd/command.c.
1304 * Fixed fatal bug in CLOSE command. The server_entry became
1305 invalid but was referenced later in the command. Affected file
1308 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Fixed fatal bug in failure packet handling. Server ignored
1311 the failure and thus crashed when it came.
1315 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1317 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1318 that the command may be executed only once in (about) 2 seconds.
1319 The old SILC_CF_LAG flag is same but allows command bursts up
1320 to five before limiting.
1322 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1323 server code. Various commands now includes the CF_LAG_STRICT
1324 flag to disallow any kind of miss-use of the command.
1326 * Fixed the silc_buffer_unformat to not to allocate any data
1327 if the length of the data is zero. It used to allocate the
1328 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1330 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1332 * Changed the format of AdminConnection configuration section
1333 in the server. Added username of the admin to the format.
1334 Affected files silcd/serverconfig.[ch].
1336 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1337 to return admin configuration data by host, username and/or
1340 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1342 * Implemented WHOWAS command to the server. Added the functions:
1344 silc_server_command_whowas_parse,
1345 silc_server_command_whowas_send_reply,
1346 silc_server_command_whowas_from_client and
1347 silc_server_command_whowas_from_server
1349 * Added <Client ID> argument to the WHOWAS command reply. Updated
1350 the protocol specs accordingly.
1352 * Implemented WHOWAS command and command_reply to the client
1355 Implemented the WHOWAS printing on the user interface.
1357 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1359 * Added new argument to the WHOWAS command reply, the real name.
1360 It is an optional argument. Updated the protocol specs.
1362 * Added SilcIDCacheDestructor callback that is registered when
1363 the SilcIDCache is allocated. The callback is called when
1364 an cache entry in the ID Cache expires, or is purged from the
1365 cache. Added into lib/silccore/idcache.[ch].
1367 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1368 to destruct the client entries when the cache entry expires.
1369 Other ID Cache's in server and in the client library ignores
1372 * If the ID Cache entry's `expire' field is zero then the entry
1373 never expires. Added boolean `expire' argument to the
1374 silc_idcache_add function in the lib/silccore/idcache.[ch].
1375 If it is TRUE the default expiry value is used.
1377 * Added silc_server_free_client_data_timeout that is registered
1378 when client disconnects. By default for 5 minutes we preserve
1379 the client entry for history - for WHOWAS command.
1381 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Added support to the server to enforce that commands are not
1384 executed more than once in 2 seconds. If server receives
1385 commands from client more frequently, timeout is registered
1386 to process the commands. Affected file silcd/command.c.
1387 Added new function silc_server_command_process_timeout.
1389 * Changed NICK_NOTIFY handling in client library to check that
1390 if the client's nickname was changed, so there is no need to
1391 resolve anything from the server.
1393 * Removed error printing from the WHOIS and IDENTIFY commands.
1394 If error occurs then it is ignored silently in the client library.
1395 The application, however, may map the received error to
1396 human readable error string. The application currently maps
1397 the NO_SUCH_NICKNAME error to string.
1399 * Made the command status message public to the application. Moved
1400 them from lib/silcclient/command_reply.c to
1401 lib/silcclient/command_reply.h. The application can map the
1402 received command status to the string with the
1403 silc_client_command_status_message function.
1405 * Added check to the server to check that client's ID is same
1406 as the Source ID in the packet the client sent. They must
1409 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1411 * Added dist-bzip hook to the Makefile.am to make bzip2
1412 compressed distributions.
1414 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1416 * Server now enforces the maximum length for the nickname and
1417 the channel as protocol specification dictates. 128 bytes for
1418 nickname and 256 bytes for channel name.
1420 * Moved the WHOIS printing to the application. The client libary
1421 does not print out the WHOIS information anymore, the application
1422 must do it. Renamed silc_client_command_reply_whois_print to
1423 the silc_client_command_reply_whois_save.
1425 The client's idle time is also sent to the application now, and
1426 the idle is shown on screen.
1428 * Added silc_client_command_reply_identify_save to save the
1429 received IDENTIFY entries.
1431 * Do not check for channel private keys in message sending and
1432 reception if the channel does not have the PRIVKEY mode set.
1433 Affected file lib/silclient/client_channel.c.
1435 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1437 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1438 just surfaced after chaning the JOIN procedure.
1440 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1442 * Added silc_client_get_clients_by_list to get client entries
1443 from Client ID list, that is returned for example by JOIN
1444 and USERS command replies. The application should use this
1445 function for example when JOIN command reply is received to
1446 resolve the clients already on the channel (library does not
1447 do that anymore as USERS command reply is not used in the JOIN
1448 procedure anymore). Affected files lib/silcclient/silcapi.h and
1449 lib/silcclient/idlist.c.
1451 * JOIN command reply and USERS command reply returns now SilcBuffer
1452 pointers instead of unsigned char pointers when returning
1453 the client list and mode list.
1455 * Added <Client ID> argument to the JOIN command reply, mainly
1456 for the server to identify for which client the command was
1457 originally sent. Updated protocol specs accordingly.
1459 * Added SilcDlist private_key pointer to the SilcChannelEntry
1460 in the client to support the channel private keys. Affected
1461 file is lib/silcclient/idlist.h.
1463 * Added SilcChannelPrivateKey argument to the function
1464 silc_client_send_channel_message so that application can choose
1465 to use specific private ke if it wants to. If it is not provided,
1466 the normal channel key is used, unless private keys are set.
1467 In this case the first (key that was added first) is used
1468 as the encryption key.
1470 * Implemented the support for channel private key handling.
1471 Implemented the following functions:
1473 silc_client_add_channel_private_key,
1474 silc_client_del_channel_private_keys,
1475 silc_client_del_channel_private_key,
1476 silc_client_list_channel_private_keys and
1477 silc_client_free_channel_private_keys
1479 Affected file lib/silcclient/client_channel.c.
1481 * Added the support for the private keys in the channel message
1482 sending and encryption and in the message reception and
1483 decryption. Affected funtions are
1484 silc_client_send_channel_message and silc_client_channel_message.
1486 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Added SKE's key verify callback to the client library's
1489 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1491 * Removed the statement that server (or router) must send USERS
1492 command reply when joining to the channel so that the client
1493 knows who are on the channel. Instead, the client list and
1494 client's mode list is now sent in the JOIN command reply to the
1495 client who joined channel. This is better solution.
1497 * Added function silc_server_get_users_on_channel and function
1498 silc_server_save_users_on_channel to the silcd/server.[ch].
1500 * Removed function silc_server_command_send_users from the
1503 * Do not show topic on the client library anymore. The topic is
1504 sent in the command reply notify to the application and the
1505 application must show the topic now.
1507 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1509 * Added client searching by nickname hash into the IDENTIFY and
1510 WHOIS commands in the server as they were clearly missing from
1511 them. Affected file is silcd/command.c.
1513 * Fixed a bug in private message receiving in the client library.
1514 The remote ID was freed and it wasn't supposed, now it is
1517 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1519 * Minor fix to the channel payload; allocate the data area, as it
1520 needs to be of specific length.
1522 * If the key agreement port is zero then the operating
1523 system will define the bound port. Affected files are
1524 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1526 * Added new function silc_channel_payload_decrypt into the file
1527 lib/silccore/silcchannel.[ch].
1529 * Moved the channel message etc, check from silc_packet_decrypt
1530 to applications. The library calls now a generic
1531 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1532 when the packet is either normal or special. This was done to
1533 allow more wide range of checking that was not allowed when
1534 the code was in library. Now applications can do virtually any
1535 checks to the packet and return to the library the decision how
1536 the packet should be processed. Affected files are
1537 lib/silccore/silcpacket.[ch].
1539 Added silc_server_packet_decrypt_check to the server and
1540 silc_client_packet_decrypt_check to the client library.
1542 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1543 to send with specified source and destination information.
1545 * Channel message delivery between routers was broken after the
1546 channel key distribution was fixed earlier. The channel key
1547 was used be to distributed to other routers as well which is not
1548 allowed by the protocol. Now this is fixed and channel keys
1549 really are cell specific and the channel message delivery between
1550 routers comply with the protocol specification.
1552 * Fixed various commands in server to check also the global list
1553 for the channel entry and not just the local list. The affected
1554 file silcd/command.c.
1556 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1558 * Added assert()s to buffer formatting and unformatting routines
1559 to assert (if --enable-debug) when error occurs. Affected
1560 file: lib/silcutil/silcbuffmt.c.
1562 * Changed to auto-reconnect to check whether the remote host is
1563 router and register the re-connect timeout if it is. It used
1564 to check that whether we are normal server, but router must do
1565 auto-reconnect with another router as well. Affected file
1568 * Removed the [<key len>] option from CMODE command as the cipher
1569 name decides the key length, nowadays. See the defined ciphers
1570 from the protocol specification.
1572 * Added [<hmac>] option to the CMODE command to define the HMAC
1573 for the channel. Added SILC_CMODE_HMAC channel mode.
1575 * Added [<hmac>] option for the JOIN command so that user can
1576 select which HMAC is used to compute the MACs of the channel
1579 * Added Hmac field to the Channel Message Payload. The integrity
1580 of plaintext channel messages are now protected by computing
1581 MAC of the message and attaching the MAC to the payload. The
1582 MAC is encrypted. Now, it is clear that this causes some
1583 overhead to the size of the packet but rationale for this is that
1584 now the receiver can verify whether the channel message decrypted
1585 correctly and also when private keys are set for the channel the
1586 receiver can decrypt the packet with several keys and check from
1587 the MAC which key decrypted the message correctly.
1589 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1590 lib/silccrypt/silccipher.[ch].
1592 * Added silc_hash_len to return the digest length into the
1593 lib/silcrypt/silchash.[ch].
1595 * Rewrote parts of Silc Channel Payload interface in the
1596 lib/silccore/silcchannel.[ch]. The encode function now also
1597 encrypts the packet and parse function decrypts it.
1599 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1601 * Fixed a minor formatting bug in the SKE's key material processing.
1602 It actually might have processed the keys wrong way resulting
1605 * Redefined the mandatory HMAC algorithms and added new algorithms.
1606 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1607 and hmac-md5 truncated to 96 bits. The mandatory is now
1608 hmac-sha1-96. Rest are optional (including the one that used
1609 to be mandatory). Rationale for this is that the truncated HMAC
1610 length is sufficient from security point of view and can actually
1611 make the attack against the HMAC harder. Also, the truncated
1612 HMAC causes less overhead to the packets. See the RFC2104 for
1615 * Added new [hmac] configuration section. The SKE used to use
1616 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1617 is of course wrong. The official names that must be proposed in
1618 the SKE are the ones defined in the protocol specification
1619 (hmac-sha1-96 for example). The user can configure any hmac
1620 using any hash function configured in the [hash] section. At
1621 least, the mandatory must be configured.
1623 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1625 * Added HMAC list to the SKE proposal list. It has now both
1626 hash algorithm list and HMAC list. This makes the protocol
1627 incompatible with previous versions. The SKE now seems to work
1628 the way it is supposed to work, for the first time actually.
1630 * Defined plain Hash algorithms to the protocol specification.
1633 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1635 * Implemented support for key agreement packets into the server.
1636 Added functions silc_server_key_agreement and
1637 silc_server_send_key_agreement. Other than these functions,
1638 server has nothing to do with this packet.
1640 * Added support for private message key packets into the server.
1641 Added functions silc_server_private_message_key and
1642 silc_server_send_private_message_key.
1646 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1647 called in the protocol's final callback instead in the END
1648 protocol state. This makes a little more sense and in the same
1649 time in client we can use the same protocol routines for normal
1650 key exchange and to key agreement packet handling as well.
1652 * Added to both client's and server's KE protocol context the
1653 SilcSKEKeyMaterial pointer to save the key material. We will
1654 bring the key material to the protocol's final callback by doing
1655 this. The final callback must free the key material.
1657 * Added SKE's packet_send callback into client's KE protocol
1658 context so that the caller can choose what packet sending function
1659 is used. This way we can use different packet sending when
1660 doing normal SKE when doing key agreement packet handling (in
1661 the key agreement packet handling we do not want to encrypt
1664 * Implemented the responder side of the key agreement routines
1665 in the client. The client can now bind to specified port and
1666 accept incoming key negotiation. The key material is passed
1667 to the application after the protocol is over.
1669 * Implemented the processing of incoming Key Agreement packet
1670 in the client. Added function silc_client_key_agreement to
1673 * Implemented the intiator side of the key agreement routines
1674 in the client. The client can now initiate key agreement with
1675 another remote client. The key material is passed to the
1676 application after the protocol is over.
1678 * Created client_keyagr.c to include all the key agreement
1681 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1682 SILC_TASK_CALLBACK except that it is not static.
1684 * Created client_notify.c and moved the Notify packet handling
1685 from the client.[ch] into that file.
1687 * Created client_prvmsg.c and moved all private message and
1688 private message key routines from the client.[ch] into that file.
1690 * Create client_channel.c and moved all channel message and
1691 channel private key routines from the client.[ch] into that file.
1693 * Changed silc_client_get_client_by_id_resolve to resolve with
1694 WHOIS command instead of IDENTIFY command, in the file
1695 lib/silclient/idlist.c.
1697 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1699 * Implemented the SKE's responder side to the Client library.
1701 * When FAILURE is received to the protocol do not trust it
1702 blindly. Register a timeout to wait whether the remote closes
1703 the connection as it should do it, only after that process the
1704 actual failure. This was changed to both client and server.
1706 * Added client_internal.h to include some of the structures
1707 there instead of client.h in lib/silcclient/.
1709 * Added function silc_task_unregister_by_callback to unregister
1710 timeouts by the callback function.
1712 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1714 * Some "Incomplete WHOIS info" errors has been appearing on the
1715 log files. Took away the entry->userinfo check from WHOIS
1716 reply sending. The entry->userinfo is now " " if client did not
1717 provide one. I thought this was fixed earlier but something
1718 is wrong still. Let's see if the error still appears.
1720 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1722 * Fixed a minor bug in the login when the channel key is
1723 re-generated in the server. It used to generate the key in
1724 wrong order and thus caused problems in the channel traffic.
1726 * Fixed a minor bug in channel key distsribution after
1727 KICK command. The key was not sent to the router even though
1730 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1732 * Added silc_ske_process_key_material_data as generic routine
1733 to process any key material as the SILC protocol dictates. The
1734 function is used by the actual SKE library but can be used by
1735 applications as well. This relates to the private message keys
1736 and the channel private keys since they must be processed the
1737 same way the normal SILC session keys. The protocol dictates
1738 this. Affected files: lib/silcske/silcske.[ch].
1740 Added also silc_ske_free_key_material to free the
1741 SilcSKEKeyMaterial structure.
1743 * Defined silc_cipher_set_key function to set the key for
1744 cipher without using the object's method function. The affected
1745 files: lib/silccrypt/silccipher.[ch].
1747 * Implemented silc silc_client_add_private_message_key,
1748 silc_client_add_private_message_key_ske,
1749 silc_client_del_private_message_key,
1750 silc_client_list_private_message_keys and
1751 silc_client_free_private_message_keys functions in the
1754 Added functions silc_client_send_private_message_key to send
1755 the Private Message Key payload and silc_client_private_message_key
1756 to handle incoming Private Message Key payload.
1758 * Added Cipher field to the Private Message Key payload to set
1759 the cipher to be used. If ignored, the default cipher defined
1760 in the SILC protocol (aes-256-cbc) is used.
1762 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1764 * Removed lib/silcclient/ops.h file.
1766 Redefined parts of the SILC Client Library API. Created new
1767 file silcapi.h that deprecates the ops.h file and defines the
1768 published Client Library API. Defined also private message key
1769 API and channel private key API into the file.
1771 This is the file that the application must include from the
1772 SILC Client Library. Other files need not be included by
1773 the application anymore.
1775 * Added new key_agreement client operation callback and also
1776 defined the Key Agreement library API for the application.
1778 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1780 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1781 is used by clients to request key negotiation between another
1782 client in the SILC network. If the negotiation is started it
1783 is performed using the SKE protocol. The result of the
1784 negotiation, the secret key material, can be used for example
1785 as private message key.
1787 Implemented the Key Agreement payload into the files
1788 lib/silccore/silauth.[ch].
1790 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Redefined ciphers for the SILC protocol. Added some new ciphers
1793 and defined the key lengths for the algorithms. Changed the
1794 code accordingly. The default key length is now 256 bits.
1796 * Fixed SKE key distribution function silc_ske_process_key_material
1797 when the key length is more than 128 bits. The default key
1798 length in SILC is now 256 bits.
1800 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1801 to indicate unsupported algorithm.
1803 * Renamed rijndael.c to aes.c and all functions as well.
1805 * Fixed a long standing channel key setting bug in client library.
1806 Weird that it has never surfaced before.
1808 * Fixed bug in channel deletion. If the entire channel is removed
1809 then it must also delete the references of the channel entry
1810 from the client's channel list as the client's channel entry and
1811 the channel's client entry share same memory.
1813 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1815 * Implemented CONNECT and SHUTDOWN commands in the client.
1817 * Implemented CLOSE command to the client.
1819 * Added the function silc_idlist_find_server_by_name into the
1820 files silcd/idlist.[ch].
1822 Added the function silc_idlist_find_server_by_conn into the
1823 files silcd/idlist.[ch].
1825 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1827 * DIE command was renamed to SHUTDOWN. Updated the both code
1830 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1831 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1833 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1836 * Added function silc_server_create_connection function to create
1837 connection to remote router. My server implementation actually
1838 does not allow router to connect to normal server (it expects
1839 that normal server always initiates the connection to the router)
1840 so the CONNECT command is only good for connecting to another
1843 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1845 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1846 or some other client was kicked from the channel.
1848 Implemented the handling of the notify type to both client
1851 Implemented silc_server_send_notify_kicked to send the KICKED
1852 notify. It is used to send it to the server's primary router.
1854 * Implemented the KICK command into server and client.
1856 * Added `query' argument to the silc_idlist_get_client function
1857 to indicate whether to query the client from server or not if
1860 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1861 to indicate that the client is not channel founder.
1865 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1867 * Removed the rng context from SilcPacketContext structure and
1868 changed that the packet routine uses the Global RNG API.
1870 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1872 * Added support for quit message that client can "leave" on the
1873 channel when it quits the SILC. It is ditributed inside the
1874 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1876 Added silc_server_free_client_data that will take the
1877 signoff message as argument.
1879 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1881 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1883 * Updated parts of the protocol specification to keep it up
1886 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1888 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1889 payloads in one packet.
1891 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1892 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1893 use now the new List flag.
1895 * Also deprecated the following packet types: REPLACE_ID,
1896 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1898 * Added list support for Notify packet in server.
1900 * Added silc_server_send_notify_channel_change to send the
1901 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1902 the silc_server_send_replace_id.
1904 * Added silc_server_send_notify_nick_change to send the
1905 NICK_CHANGE notify type. Deprecates the function
1906 silc_server_send_replace_id.
1908 * Added silc_server_send_notify_join to send the JOIN notify type.
1909 Deprecates the function silc_server_send_new_channel_user.
1911 * Added silc_server_send_notify_leave to send LEAVE notify type.
1912 Deprecates the function silc_server_send_remove_channel_user.
1914 * Added silc_server_send_notify_cmode and
1915 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1916 types. Deprecates the silc_server_send_set_mode function.
1918 * Added SERVER_SIGNOFF notify type to indicate that server has
1919 quit. This means that all clients on the channel from that
1920 server will drop. This can be also used when netsplit happens.
1922 Deprecated REMOVE_ID packet type since it is not needed anymore
1925 Added silc_server_send_notify_server_signoff to send the
1926 SERVER_SIGNOFF notify type. Deprecates the function
1927 silc_server_send_remove_id.
1929 Added also silc_server_send_notify_signoff to send the
1930 SIGNOFF notify type.
1932 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1933 SILC protocol from this day on. Changed the protocol
1934 specification as well.
1936 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1937 notify type. It is used between routers to notify about
1938 topic changes on a channel.
1940 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1943 * Partly updated the protocol specification to comply with the
1944 changes now made. It is still though a bit outdated.
1946 * The JOIN notify type now takes one extra argument <Channel ID>.
1947 The packet used to be destined to the channel but now the
1948 JOIN type may be sent as list thus it is impossible to
1949 destine it to any specific channel. By adding this argument
1950 it is again possible.
1952 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1954 * Added CREDITS file. The CHANGES and CREDITS file will appear
1955 in the distribution as well.
1957 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1959 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1960 types in the server's silcd/packet_receive.c.
1962 * Implemented CMODE and CUMODE to work in router environment.
1964 * Fixed minor encoding and decoding buglet from the
1965 lib/silccore/silcmode.c.
1967 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1970 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1972 * Changed all SilcConfigServer* and silc_config_server* to
1973 SilcServerConfig* and silc_server_config*, respectively.
1976 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1978 * Associated the ID (client or server ID) to the Authentication
1979 Payload to avoid any possibility of forging. Updated the
1980 protocol specification and the code accordingly.
1982 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1984 * The RSA key length is now save to the RsaKey context in the
1985 key generation process in lib/silccrypt/rsa.c. The key length
1986 is now used to figure out the maximum size of the block allowed
1987 to be encrypted/signed.
1989 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1990 is equivalent to the silc_mp_mp2bin but does not allocate any
1993 * Changed silc_mp_mp2bin API to take length argument. If it is
1994 non-zero then the buffer is allocated that large. If zero, then
1995 the size is approximated using silc_mp_sizeinbase, which however
1998 * Created Global RNG API which is global RNG that application can
1999 initialize. After initializing, any routine anywhere in the
2000 code (including library) can use RNG without allocating a new
2001 RNG object. This was done to allow this sort of use of the
2002 RNG in code that has no chance to allocate RNG object. All
2003 applications currently allocate this and many routines in the
2004 library use this. Affected file lib/silccrypt/silcrng.[ch].
2006 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2007 it to use the Global RNG API.
2009 * Defined Authentication Payload into protocol specification that
2010 is used during SILC session to authenticate entities. It is
2011 used for example by client to authenticate itself to the server
2012 to obtain server operator privileges.
2014 Implemented this payload into the lib/silccore/silcauth.[ch].
2015 Implemented also routines for public key based authentication
2016 as the new protocol specification dictates.
2018 Moved definitions of different authentication methods from
2019 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2021 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2022 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2023 silc_pkcs_verify_with_hash functions into the file
2024 lib/silccrypt/silcpkcs.[ch].
2026 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2028 * The client entry's userinfo pointer must be always valid.
2029 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2030 will fail since it requires the userinfo. Now, the userinfo
2031 is allocated as "" if actual userinfo does not exist. Actually,
2032 it must exist and it is totally Ok to drop client connections
2033 that does not announce the userinfo. However, we will make
2034 this workaround for now.
2036 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2037 to return the remote port by socket.
2039 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2042 SILC_SERVER_PENDING_EXEC and added an new macro
2043 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2044 data or when error occurs while processing the pending command.
2046 Added new argument `destructor' into silc_server_command_pending
2047 and to the SilcServerCommandPending object. This destructor is
2048 now called after calling the pending callback or if error occurs
2049 immediately. If error occurs the actual pending callback won't
2050 be called at all - only the destructor. The destructor may be
2051 NULL if destructor is not needed.
2053 All this applies for client library code as well. Similar
2054 changes were made there as well for the pending commands.
2056 In the client, the application must now allocate the
2057 SilcClientCommandContext with the silc_client_command_alloc
2060 * Added reference counter to the SilcServerCommandContext. Added
2061 function silc_server_command_alloc and silc_server_command_dup
2064 Same type of functions added to the client library for the same
2067 * Removed the cmd_ident from IDListData away since it is now
2068 global for all connections. It is the command identifier used
2069 in command sending and with pending commands. The affected file
2072 * Added reference counter to the SilcSocketConnection objecet to
2073 indicate the usage count of the object. The object won't be
2074 freed untill the reference counter hits zero. Currently only
2075 server uses this, and client ignores it. The client must be
2076 set to use this too later. The affected files are
2077 lib/silccore/silcsockconn.[ch]. Added also the function
2078 silc_socket_dup to increase the reference counter.
2080 This was mainly added because it is possible that the socket
2081 is removed underneath of pending command or other async
2082 operation. Now it won't be free'd and proper DISCONNECTING
2083 flags, etc. can be set to avoid sending data to connection that
2084 is not valid anymore.
2086 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2087 the connection. After that it sets SILC_SET_DISCONNECTED.
2088 It is, however, possible that the socket data is not still freed.
2089 The silc_server_packet_process now checks that data is not
2090 read or written to connection that is DISCONNECTED. The socket
2091 get's freed when the reference counter hits zero.
2093 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2095 * Changed the client operation API: channel_message operation's
2096 `sender' is now the client entry of the sender, not the nickname
2097 and the `channel' is the channel entry, not the channel name.
2099 In the private_message operation the `sender' is now also the
2100 client entry of the sender not the nickname.
2102 Affected file is lib/silcclient/ops.h and all applications
2103 using the client operations.
2105 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Moved the calling of ops->connect() from connect_to_server_final
2108 into receive_new_id functin since that is the point when the
2109 client is actually allowed to send traffic to network. The
2110 affected file is lib/silcclient/client.c.
2112 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2114 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2115 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2116 (if needs broadcasting) instead of broadcasting the packets one
2117 by one which would make a burst in the network traffic.
2119 * Added `broadcast' argument to the functions in silcd/server.[ch]
2120 silc_server_create_new_channel[_with_id] to indicate whether
2121 to send New Channel packet to primary router.
2123 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2125 * Added new function into the silcd/server.[ch] files:
2126 silc_server_create_new_channel_with_id to create new channel with
2127 already existing Channel ID.
2129 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2130 lib/silccore/silcpacket.h. This packet is used t send list of
2131 Set Mode payloads inside one packet. Server uses this to set
2132 the modes for the channels and clients on those channels, that it
2133 announced to the router when it connected to it. The protocol
2134 specification has been updated accordingly.
2136 * The silc_server_new_channel did not handle the packet coming
2137 from normal server as it normally does not send that. However,
2138 when it announces its channels it does send it. Implemented
2139 the support for that.
2141 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2142 into the file lib/silccore/id.h.
2144 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2146 * Fixed memory leaks in the functions silc_idlist_del_client,
2147 silc_idlist_del_channel and silc_idlist_del_server in the file
2148 silcd/idlist.c. All of those leaked like a sieve.
2150 * Fixed some small memory leaks in the client's function
2151 silc_client_notify_by_server.
2153 * Added functions into silcd/server.c: silc_server_announce_clients,
2154 silc_server_announce_channels and silc_server_announce_server.
2155 These functions are used by normal and router server to announce
2156 to its primary router about clients, channels and servers (when
2157 router) that we own. This is done after we've connected to the
2160 These functions effectively implements the following packet types:
2161 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2162 and SILC_PACKET_NEW_ID_LIST.
2164 * Added new functions into the silcd/packet_receive.[ch]:
2165 silc_server_new_id_list, silc_server_new_channel_list and
2166 silc_server_new_channel_user_list to handle the incoming
2167 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2169 * Added support of changing Channel ID in the function
2170 silc_server_replace_id. If the server that announces a channel
2171 to the router already exists in the router (with same name but
2172 with different Channel ID), router is responsible to send
2173 Replace ID packet to the server and force the server to change
2174 the Channel ID to the one router has.
2176 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2177 client that the Channel ID has been changed by the router. The
2178 normal server sends this to the client. Client must start using
2179 the new Channel ID as the channel's ID.
2181 Implemented handling of this new type into lib/silcclient/client.c
2182 into the function silc_client_notify_by_server.
2184 * Added new function silc_idlist_replace_channel_id into the files
2185 silcd/idlist.[ch] to replace the Channel ID.
2187 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2189 * Call silc_server_command_identify_check always when processing
2190 the IDENTIFY command in silcd/command.c
2192 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2194 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2195 send keepalive packets. The packet can be sent by clients,
2196 servers and routers.
2198 Added function silc_socket_set_heartbeat into the file
2199 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2200 If not set, the heartbeat is not performed. The actual
2201 heartbeat is implemented in the low level socket connection
2202 library. However, application is responsible of actually
2205 Added silc_server_send_heartbeat to send the actual heartbeat
2206 packet into silcd/packet_send.[ch]. Server now performs
2207 keepalive with all connections.
2209 * Added silc_task_get_first function into lib/silcutil/silctask.c
2210 to return the timeout task with shortest timeout. There was a bug
2211 in task unregistration that caused problems. TODO has been
2212 updated to include that task system must be rewritten.
2214 * The client library will now resolve the client information when
2215 receiving JOIN notify from server for client that we know but
2216 have incomplete information.
2218 * Rewrote parts of silc_server_remove_from_channels and
2219 silc_server_remove_from_one_channel as they did not remove the
2220 channel in some circumstances even though they should've.
2222 * Encryption problem encountered in server:
2224 The LEAVE command used to send the Channel Key packet to the
2225 router immediately after generating it. However, the code
2226 had earlier sent Remove Channel user packet but not immediately,
2227 ie. it was put to queue. The order of packets in the router
2228 was that Channel Key packet was first and Remove Channel User
2229 packet was second, even though they were encrypted in the
2230 reverse order. For this reason, MAC check failed. Now, this
2231 is fixed by not sending the Channel Key packet immediately but
2232 putting it to queue. However, this is more fundamental problem:
2233 packets that are in queue should actually not be encrypted
2234 because packets that are sent immediately gets encrypted
2235 actually with wrong IV (and thus MAC check fails). So, packets
2236 that are in queue should be encrypted when they are sent to
2237 the wire and not when they put to the queue.
2239 However, the problem is that the current system has not been
2240 designed to work that way. Instead, the packet is encrypted
2241 as soon as possible and left to the queue. The queue is then
2242 just purged into wire. There won't be any fixes for this
2243 any time soon. So, the current semantic for packet sending
2246 o If you send packet to remote host and do not force the send
2247 (the packet will be in queue) then all subsequent packets to the
2248 same remote host must also be put to the queue. Only after the
2249 queue has been purged is it safe again to force the packet
2252 o If you send all packets immediately then it safe to send
2253 any of subsequent packets through the queue, however, after
2254 the first packet is put to queue then any subsequent packets
2255 must also be put to the queue.
2257 Follow these rules and everything works fine.
2259 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Added new function silc_server_remove_clients_by_server to
2262 remove all client entries from ID list when the server connection
2263 is lost. In this case it is also important to invalidate all
2264 client entires as they hold the invalid server entry. This
2265 fixes fatal bug when server has lost connection and will reconnect
2268 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2270 * Made some sanity checks to silc_server_daemonise like to check
2271 whether the requested user and group actually exists.
2273 * Added sanity check to SKE's silc_ske_responder_finish to check
2274 that the public and private key actually is valid.
2276 * Invalidate the client's nickname when receiving Replace ID
2277 packet and the Client ID is being replaced. This means that the
2278 server will query the nickname if someone needs it (client)
2281 * Sort the ID Cache in client library when the ID Cache data
2282 has changed (needs sorting).
2284 * Do not allow for SILC client to create several connections to
2285 several servers. The client does not support windows right now
2286 and generating multiple connections causes weird behaviour.
2288 Irssi-silc client does support windows and can handle several
2289 connections without problems, see: www.irssi.org and SILC plugin.
2291 * Fixed some places where client was added to the IDList. The
2292 rule of thumb is following (in order to get everything right):
2293 If the client is directly connected local client then the
2294 `connection' argument must be set and `router' argument must be
2295 NULL to silc_idlist_add_client function. If the client is not
2296 directly connected client then the `router' argument must
2297 bet set and the `connection' argument must be NULL to the
2298 silc_idlist_add_client function.
2300 * The funtion silc_server_packet_send_local_channel actually did
2301 not check whether the client was locally connected or not. It
2302 does that now. Fixed a bug related to LEAVE command.
2304 * Fixed Remove Channel User payload parsing bug in server's
2305 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2307 * The server's silc_server_save_channel_key now checks also the
2308 global ID list for the channel as it might not be in the local
2309 list. Fixed a bug related to LEAVE command.
2311 * Is this the end of the [<unknown>] buglet that has been lurking
2312 around for a long time? A little for loop fix in server's
2313 silc_server_command_whois_parse that is used by both IDENTIFY
2314 and WHOIS command. At least, this was a clear bug and a cause
2315 of one type of [<unknown>] buglet.
2317 * WHOIS and IDENTIFY commands call the function
2318 silc_server_command_[whois/identify]_check function even if
2319 we are not router server.
2321 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2323 * Added --with-gmp configuration option. If set the GMP
2324 is always compiled in the SILC source tree. If not set then
2325 it is checked whether the system has the GMP3 installed. If
2326 it has then the GMP won't be compiled (the system's headers
2327 and library is used), if it doesn't have it then the GMP is
2328 compiled in the SILC source tree.
2330 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Changed RSA private exponent generation to what PKCS #1
2333 suggests. We try to find the smallest possible d by doing
2334 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2335 not security fix but optimization.
2337 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2339 * Added new config entry [Identity] to fork the server and run
2340 it as specific user and group. A patch from Bostik.
2342 * Imported Dotconf configuration library into lib/dotconf.
2343 This will be used to create the SILC configuration files later.
2344 It will appear in the distsribution after this commit.
2346 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2348 * A big code auditing weekend happening. Auditing code for
2349 obvious mistakes, bugs and errors. Also, removing any code
2352 Removed files for being obsolete:
2354 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2355 inline in the file lib/silcutil/silcbuffer.h)
2357 o lib/silcutil/silcbufutil.c (the header has inline versions)
2359 Changed code to fix possible error conditions:
2361 o The buffer formatting routines now check that the destination
2362 buffer really has enough space to add the data. This applies for
2363 both buffer formatting and unformatting
2364 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2365 unformatting was changed to accomodate following rules:
2366 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2367 sent to the function while XXX_*STRING will not allocate or copy
2368 the data into the buffer. Instead it sets the pointer from the
2369 buffer into the pointer sent as argument (XXX_*STRING used to
2370 require that the pointer must be allocated already). This change
2371 makes this whole thing a bit more consistent and more optimized
2372 (note that the data returned in the unformatting with XXX_*STRING
2373 must not be freed now). The routines return now -1 on error.
2375 o Tried to find all code that use buffer_format and buffer_unformat
2376 and added return value checking to prevent formatting and
2377 especially unformatting errors and possible subsequent fatal
2380 o Changed ske->x and ske->KEY to mallocated pointers in
2381 lib/silcske/silcske.h. Fixed possible data and memory leak.
2383 o Added return value checking to all *_parse* functions. Fixed
2384 many memory leaks as well.
2386 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2387 so that buffer overflows would not happen. All code now also
2388 checks the return value as it can fail.
2390 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2392 * Added reconnection support to server if the normal server looses
2393 its connection to the router (for example if router is rebooted).
2394 The server performs normal reconnection strategy implemented
2395 to the server. Affected file silcd/server.c.
2397 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2399 * Added new packet type SILC_PACKET_SET_MODE that is used to
2400 distribute the information about changed modes (for clients,
2401 channels and clients channel modes) to all routers in the
2402 network. Updated the protocol specification accordingly.
2404 Added functions into silcd/packet_send.c and
2405 silcd/packet_receive.c: silc_server_send_set_mode,
2406 silc_server_set_mode.
2408 Added new files silcmode.[ch] into lib/silccore that implements
2409 the encoding and decoding of Set Mode Payload. Added new type
2410 SilcSetModePayload. Moved the definitions of different modes
2411 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2413 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Oops, a little mistake in server's connection authentication
2416 protocol. The protocol is not ended with FAILURE but with
2417 SUCCESS if the authentication is Ok. :) Affected file is
2420 * Implemented NICK_CHANGE notify handling in server in the file
2421 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2422 the local clients on the channel. After the changing nickname
2423 in router environment snhould work and the [<unknown>] nickname
2424 should appear no more.
2426 The silc_server_replace_id function that receives the Replace ID
2427 payload now sends the NICK_CHANGE notify type also in the file
2428 silcd/packet_receive.c
2430 * Changed WHOIS and IDENTIFY command to support the maximum amount
2431 of arguments defined in protocol specs (3328 arguments). This
2432 fixed a bug that caused problems when there were more than three
2435 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Added extra parameter, command identifier, to the
2438 silc_client_send_command so that explicit command identifier
2441 Changed that ID list routines uses specific command identifier
2442 when sending WHOIS/IDENTIFY requests to the server so that they
2443 can be identified when the reply comes back.
2445 Affected files lib/silcclient/command.[ch],
2446 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2448 * Added `sender' argument to silc_server_packet_send_to_channel
2449 to indicaet the sender who originally sent the packet to us
2450 that we are now re-sending. Ignored if NULL. Affected file
2451 silcd/packet_send.[ch].
2453 * Added some server statistics support in silcd/server_internal.h
2454 SilcServerStatistics structure and around the server code. Also
2455 send some nice statistics information when client is connecting
2458 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2460 * Fixed channel ID decoding in server's JOIN command reply in
2461 silcd/command_reply.c
2463 * Fixed braodcasting of replace ID payload to not to send it if
2464 we are standalone server in silcd/packet_receive.c.
2466 * Fixed all channel message sending routines to not to send
2467 packets to clients that has router set, since they are routed
2468 separately in the same function earlier. Affects file
2469 silcd/packet_send.c and all channel packet sending functions.
2471 * In USERS reply, res_argv[i] are not allocated, the table
2472 is allocated. Thus changed that free the table, not its
2475 * In server's whois_check and identify_check if the client is
2476 locally connected do not send any WHOIS commands - they are not
2479 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2481 * Fixed some minor bugs in client when sending WHOIS command. The
2482 arguments was in wrong order.
2484 * Removed statis function add_to_channel from server in
2485 silcd/command.c that was previously used with the joining but
2488 * Tested USERS command in router environment successfully with two
2489 routers, two servers and two clients.
2491 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Reorganized the USERS command and command reply in client library
2494 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2495 When the command is given by user we register a pending command
2496 callback that will reprocess the command after the reply has been
2497 received from the server. When reprocessing the packet we then
2498 display the information. Thus, the USERS information is displayed
2499 now in the command callback instead of in the command reply
2500 callback. The processing of the command is same as previously
2501 when server has sent the command reply in the JOINing process.
2503 * Added to USERS command in silcd/command_reply.c to join the client,
2504 we didn't use to know about, to the channel after we've created
2505 a client entry for it. Also, for clienet we did know already still
2506 check whether it is on the channel or not and add it if not.
2508 * Removed silc_server_command_join_notify as the function and its
2511 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2513 * Changed the client's pending command handling to the same as the
2514 server's pending command handling. It is also now possible to
2515 execute command reply functions from other command reply
2516 function as the function callbacks for commands and command
2517 replies are one and same. The pending commands are not static
2518 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2519 in client connection context. Thus, pending commands are server
2520 connection specific as it is convenient.
2522 Changed the function silc_client_command_pending and
2523 silc_client_command_pending_del and added new function
2524 silc_client_command_pending_check. Removed the
2525 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2528 * Added cmd_ident, current command identifier, to the client
2529 connection context in lib/silcclient/client.h to keep track on
2530 command identifiers used in command sending. Client's command reply
2531 function handling now supports the mandatory command identifiers.
2533 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2534 funtions in client to fully support pending command callbacks.
2536 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2537 as one of the arguments to the application in the command reply
2540 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2541 before first releasing SILC but came back. Now it is removed again
2542 and should come back nomore. The FORWARDED flag was used only
2543 by the JOINing procedure by forwarding the command packet to router.
2544 Now, the JOINing procedure has been changed to more generic (due
2545 to various router environment issues) and FORWARDED is not needed
2546 anymore for anything. The protocol specification is yet to be
2549 Now, removed silc_server_packet_forward from server and the flag
2550 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2552 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2554 * Renamed NAMES command to USERS command. The NAMES was named that
2555 due to historical reasons. Now it is renamed. Also, rewrote
2556 parts of the USERS command. The nickname list is not sent anymore
2557 by the server. Only Client ID and mode lists are sent in the USERS
2558 command. Changed this also to the protocol specification.
2560 The client now resolves the names and stuff after it receives
2561 the USERS list from the server when joining to the channel.
2563 * WHOIS and IDENTIFY commands has been changed to support multiple
2564 Client ID's per command. One can now search for multiple users
2565 in the network by sending only one WHOIS or IDENTIFY command.
2566 Changed the code and the protocol specifications.
2568 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2569 uses silc_server_command_whois_parse to parse the request. */
2571 * If normal server, do not parse the WHOIS and IDENTIFY requests
2572 before sending it to the router. Saves some time.
2574 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2576 * Fixed JOIN command on client library. Wrong number of arguments
2577 used to crash the client.
2579 * Added silc_server_channel_has_global function to check whether
2580 channel has global users or not.
2582 * Added silc_server_channel_has_local function to check whether channel
2583 has locally connected clients on the channel.
2585 * The silc_server_remove_from_one_channel now checks whether the
2586 channel has global users or not after given client was removed from
2587 the channel. It also checks whether the channel has local clients
2588 on the channel anymore. If it does not have then the channel entry
2589 is removed as it is not needed anymore.
2591 * The silc_server_notify now checks on JOIN notify whether the joining
2592 client is one of locally connected or global. If it is global then
2593 the channel has now global users on the channel and that is marked
2594 to the channel entry. Also, it now saves the global client to
2595 global list who is joining and JOINs it to the channel. This is
2596 for normal server, that is.
2598 Changed silc_server_send_notify_on_channel,
2599 silc_server_packet_relay_to_channel and
2600 silc_server_packet_send_to_channel check if we are normal server
2601 and client has router set (ie. global client) do not send the
2602 message to that client, as it is already routed to our router.
2604 * Implemented LEAVE notify type handling in silc_server_notify
2607 * Tested LEAVE command in router environment successfully. Tested
2608 with two routers, two servers and two clients.
2612 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2614 * Implemented SIGNOFF notify type handling in silc_server_notify
2617 * silc_server_remove_id now removes the client entry from all channels
2618 it has joined and thusly sends SIGNOFF notify type.
2620 * Rewrote the NAMES list generation in server by removing two excess
2621 loops. The lists are created now inside one loop.
2623 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2625 * silc_server_remove_channel_user checks now also global list
2626 for channel and client.
2628 * silc_server_new_channel_user checks now both local and global
2629 list for channel and client. Fixed a bug in client id decoding.
2630 Used to decode wrong buffer.
2632 * silc_server_channel_message checks now both local and global
2633 list for channel entry.
2635 * Tested channel joining (hence JOIN) in router environment
2636 successfully. Tested with two routers, two servers and two
2639 * Tested channel message sending in router environment successfully.
2641 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2643 * Added silc_server_save_channel_key into server.[ch] to save the
2644 received channel key in Channel Key payload processing. It is
2645 also used in JOIN command reply handling.
2647 Equivalent function silc_client_save_channel_key added into
2648 client.[ch] into client library.
2650 * Changed JOIN command reply to send information whether the channel
2651 was created or not (is existing already) and the channel key
2652 payload. Changed protocol specs accordingly.
2654 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2655 the request was sent by ID and not by nickname. Crashed on
2658 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2660 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2661 now correctly save the received data.
2663 * silc_server_free_sock_user_data now notifies routers in the
2664 network about entities leaving the network.
2666 At the same time implemented functions silc_server_remove_id
2667 and silc_server_send_remove_id to receive and send REMOVE_ID
2668 packets. The packet is used to notify routers in the network
2669 about leaving entities. The ID removed will become invalid in
2672 * Added function silc_idlist_del_server into server. Removes and
2673 free's server entry from ID list.
2675 * silc_server_private_message function now checks, if we are router,
2676 that the destination ID really is valid ID, naturally.
2678 * In router when NEW_ID packet is received (for new client) the
2679 hash of the Client ID is saved in the ID Cache but the
2680 client->nickname is set to NULL, instead of putting the hash
2683 IDENTIFY command now also checks that client->nickname must be
2684 valid. If it is not if will request the data from the server who
2685 owns the client. Added new function
2686 silc_server_command_identify_check.
2688 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2689 to set the command to already allocated Command Payload.
2691 * Tested private message sending in router environment with two
2692 routers, two servers and two clients. Fixed minor bugs and now
2695 * Fixed segfault from client's NAMES command. Used to crash if
2698 * Forwarded packets must not be routed even if it is not destined
2699 to the receiver. Changed server code comply with this.
2701 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2703 * Added `require_reverse_mapping' boolean value to ServerParams
2704 structure. If TRUE (not default) the server will require that
2705 the connecting host has fully qualified domain name.
2707 If the reverse mapping is not required and hostname could not be
2708 found the IP address is used as hostname.
2710 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2712 * Implemented version string checking to both client and server.
2713 The check is incomplete currently due to the abnormal version
2714 strings used in development version of SILC.
2716 * Changed all command functions in server to use the new
2719 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Changed char *data to unsigned char *data in ID Cache system to
2722 support binary data as ID Cache data. Changed code to support
2723 binary data in lib/silccore/idcache.c.
2725 * Renamed silc_server_packet_relay_command_reply to
2726 silc_server_command_reply as it is normal packet receiving
2727 function. Rewrote the function to accept command replys for
2728 servers and not only for clients.
2730 * Mark remote router always as registered server if we are connecting
2731 to it. Otherwise, commands sent by the router to us are ignored.
2733 * All ID List find routines now returns the ID Cache Entry pointer
2734 as well if requested.
2736 * WHOIS command works now in router environment, tested with two
2737 routers, two servers and two clients.
2739 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2740 in router environment (as it is almost equivalent to WHOIS) but
2741 hasn't been tested thoroughly. Added new functions:
2743 silc_server_command_identify_parse
2744 silc_server_command_identify_send_reply
2745 silc_server_command_identify_from_client
2746 silc_server_command_identify_from_server
2748 * Disabled route cache adding because adding two different ID's with
2749 same IP replaces the old cache entry thus giving wrong route.
2750 The entry->router->connection is always the fastest route anyway
2751 so route cache may not be needed. Of course, new routes maybe
2752 established after receiving the ID when the entry->router->connection
2753 might not be anymore the most optimal.
2755 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2757 * Add route cache for received ID for fast routing.
2759 * Added silc_server_packet_route to route received packet on router
2760 that is not destined to us.
2762 * Renamed silc_server_get_route to silc_server_route_get.
2764 * Added id_string and id_string_len fields into SilcServer to
2765 include encoded ServerID for fast comparing without excess
2766 encoding of the ID's.
2768 * Cleaned up WHOIS command on server side. Added following static
2771 silc_server_command_whois_parse
2772 silc_server_command_whois_check
2773 silc_server_command_whois_send_reply
2774 silc_server_command_whois_from_client
2775 silc_server_command_whois_from_server
2777 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2778 arguments in command replies. All command functions should be
2779 updated to use this macro.
2781 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2783 * Minor typo fixes on command reply handling on server.
2785 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Added silc_server_command_add_to_channel internal routine to add
2788 the client to the channel after router has created the channel and
2789 sent command reply to the server.
2791 * Added generic silc_server_send_command to send any command from
2794 * Use static buffer with ID rendering instead of duplicating data.
2796 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2798 * Fixed a channel user mode bug when joining to a channel server gave
2799 everybody channel founder rights, oops.
2801 * We mark ourselves as the router of the incoming server connection
2802 if we are router ourselves. This way we can check in some packet
2803 sending functions whether it is locally connected server. For
2804 incoming router connections we put NULL.
2806 * For router sending packets locally means now always sending the
2807 packet cell wide; to local clients and local servers. For normal
2808 server sending packet locally means sending it to only local
2811 * Fixed the JOIN command to really work in router environment. If the
2812 channel is created it is always created by the router. Router is
2813 also responsible of making the initial joining to the channel,
2814 sending JOIN notify to the sending server and distributing
2815 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2816 does not exist server doesn't do anything else but forward the
2817 command to the router which performs everything.
2819 * Added silc_server_send_channel_key function to send the Channel Key
2822 * Added silc_server_create_channel_key to create new channel key. The
2823 channel key is now re-generated everytime someone joins or leaves
2824 a channel, as protocol dictates. Note: channel->key_len is the
2827 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2830 packet_receive.[ch] to separate packet sending and receiving
2831 routines. The server.[ch] now includes everything else including
2832 actual packet processing (writing and reading data) and other
2835 Renamed silc_server_private_message_send_internal to
2836 silc_server_send_private_message. The routine is still though
2837 used only to relay private messages as server does not send
2838 private messages itself.
2840 Renamed silc_server_new_channel to silc_server_create_new_channel
2841 and added new function sicl_server_new_channel that handles the
2842 incoming New Channel packet. Added also new sending function
2843 silc_server_send_new_channel to send New Channel Payload.
2845 * Added new function silc_server_notify to process incoming notify
2846 packet to the server/router. Server may then relay the notify
2847 to clients if needed.
2849 * Added new function silc_server_new_channel_user to process incoming
2850 New Channel User packet. Router will redistribute the packet and
2851 send JOIN notify to its local clients and locally connected servers
2852 if needed. Normal server will send JOIN notify to its local client
2853 on same channel when received this packet. Added also corresponding
2854 sending function silc_server_send_new_channel_user to sent the
2857 * Added boolean route argument to send_notif_to_channel and
2858 packet_send_to_channel functions to attempt to route the packet
2859 if it is TRUE and send only locally if it is FALSE.
2861 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2863 * silc_server_replace_id now broadcasts the received replace ID
2864 packet if it is not broadcast packet already. The router must
2865 broadcast to inform other routers about changed ID.
2867 * Added backpointer to server's router into SilcServer context in
2868 silcd/server_internal.h.
2870 * Fixed silc_server_packet_broadcast to send correct broadcast
2873 * The channel key is now distributed to the local client as soon
2874 as it is received from the router (in router environment) so that
2875 no other packet may be sent for the channel until client has
2878 * silc_server_remove_channel_user now broadcasts the received
2879 Remove Channel User packet if it is not broadcast packet already.
2880 The router must broadcast to inform other routers about removed
2883 * Added users field into SilcPacketContext that is a reference count
2884 of the context. One can increase the reference count by calling
2885 silc_packet_context_dup which is now changed to just increase the
2886 reference count instead of duplicating the data. The reference
2887 count is decresed by calling silc_packet_context_free that will
2888 free the data after the reference count hits zero.
2890 For now on the packet context and everything allocated into it
2891 (including the raw packet from network) must be freed by calling
2892 the new silc_packet_context_free function. Added also new function
2893 silc_packet_context_alloc that must be used now to allocate the
2894 context. This also means that if a routine is asynchronous from
2895 silc_[client/server]_packet_parse_type the packet context must
2896 be duplicated by calling silc_packet_context_dup. Otherwise it
2897 gets free'd after silc_[client/server]_packet_parse_type returns.
2898 Also, one must remember that if packet is duplicated then its
2899 reference count must be decresed by calling the free function as
2900 many times as it was duplicated.
2902 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2903 from both client and server.
2905 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2907 * Made joining to a channel working in router environment.
2909 * Cleaned up JOIN command on server side and create function
2910 silc_server_command_join_channel internal routine to make the
2913 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2915 * Changed silc_command_pending list to SilcDList. Also, added
2916 `ident' field to SilcServerCommandPending structure to identify
2917 the reply and to call correct callback.
2919 Added silc_server_command_pending_check function to replace the
2920 corresnponding macro. The silc_command_pending list is not
2923 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2924 to set identifier to previously allocated Command Payload. It
2925 is used to set identifier for command when resending Command
2928 * Added silc_command_payload_encode_payload to encode Command
2929 Payload buffer from SilcCommandPayload structure.
2931 * Added silc_argument_payload_encode_payload to encode Argument
2932 payload buffer from SilcArgumentPayload structure.
2934 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Changed WHOIS command to support router connection on server side.
2937 The whois request is always sent to router unless the server is
2938 standalone server. After server has received the reply from the
2939 router will it send the reply to the client.
2941 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2942 broadcast received broadcast packet. The function is used only
2943 by router. The broadcast packet is always sent to the router's
2946 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2947 render given ID to printable string, for log files for example.
2949 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Made basic router to router connections working. At least they
2952 can now connect to each other but nothing really works the way
2953 they are supposed - yet.
2955 * Added new initiator token to RouterConnection configuration
2956 file in silcd/serverconfig.[ch]. It is used to tell whether we
2957 are the initiator to the remote router or whether we'll expect
2958 the other end to connect.
2960 * Moved registering of listener task to silc_server_init, hence
2961 the server starts listenning as soon as it is run, even if it
2962 does not have connections to other routers. Let's see how well
2965 * Changed default connection retry timeouts for more suitable in
2968 * Removed cipher and such arguments from silc_idlist_add_client
2969 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2970 Added new function silc_idlist_add_data to add the keys and stuff
2973 * Added SilcIDListData structure and added it to SilcClientEntry
2974 and SilcServerEntry as their first field in the structure. This
2975 way we can explicitly cast the ID entries to the SilcIDListData
2976 structure and get common data for the entries. In past, we had
2977 to first check what type of connection it is and then cast it to
2978 correct ID entry type. Now, we can directly cast the opaque
2979 pointer to the SilcIDListData (no matter what ID entry it actually
2980 is) and get the data needed.
2982 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2985 in some circumstances even if threre were timeout tasks, though not
2986 IO tasks, but tasks anyway. Now fixed.
2988 * Defined SilcServerConnection structure to hold connection specific
2989 stuff about directly connected servers and routers. The definition
2990 is currently in silcd/server_internal.h. I thought about having
2991 a bit more important role fro this struct but for now it is used
2992 only when connecting to other server (or router actually).
2994 * Added connecting retry support in server when connecting to
2995 router(s). The retry feature implement exponential backoff
2996 algorithm. Also, added SilcServerParams structure to hold default
2997 parameters for server. For now, it include these retry settings
2998 and are hard coded. After server is moded to be as Silc Server
2999 Library this structure will be more important.
3001 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3003 * Changed client librarys channel->clients table to SilcList and
3004 changed code accordingly.
3006 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Changed client's channel table to SilcList and changed code
3009 accordingly. Also changed SilcChannelClientEntry to include back-
3010 pointer to the channel so that client entry can use that structure
3011 as list as well and we have fast cross-reference to the channel.
3012 This change dramatically decreased the complexity of channel
3013 handling with client entry and vice versa (removed one extra
3014 loop when searching for channel entry from many functions).
3016 * Changed server->sim from table to SilcDList and changed code
3019 * NAMES command can now be used from user interface. It will show
3020 the user list on the channel, neatly.
3022 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3023 Code now saves realname of the user if it becomes available.
3025 * Renamed configure.in to configure.in.pre and made ./prepare
3026 script to automatically add correct version string to
3027 configure.in which it creates from configure.in.pre.
3029 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * NAMES command reply now shows users mode with the nickname when
3034 * Moved silc_client_ch[u]mode[_char] functions from
3035 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3036 place sucks, they are utility functions and should be in some
3039 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3041 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3044 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Added TRQ (efficient deque and list library) into lib/trq. This is
3049 a very good list library that is currently used in the SILC. Defined
3050 SilcList API over the library because I didn't like the API very
3051 much. See lib/trq/silclist.h for the API and examples of how to
3052 use the API. Fixed various places in the code to use the new
3053 SilcList API. The SilcList is meant for lists that has a structure
3054 already defined as a list. It is not suitable to add just some
3055 context to the list (in TRQ, the context is the list actually).
3057 So, I defined SilcDList that can be used for the purpose where
3058 predefined list structure does not exit. This can be used as
3059 such list. Now some context just can be added to the SilcDList.
3060 Currently this list is not used in the SILC just yet, though there
3061 are a lot places where this can replace dynamically allocated
3062 tables and I will fix these places, later, to use SilcDList.
3063 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3064 and use TRQ internally).
3066 Also fixed some annoying warning messages that the original TRQ
3067 code generated. Also minor changes to TRQ's Makefile.in.
3069 * Added support for querying by Client ID to both WHOIS and
3070 IDENTIFY commands into server, as required by the protocol.
3072 * Removed method function pointers from SilcBuffer structure. They
3073 weren't used to anything and just increased the context size for
3074 no good reason. This change also made silc_buffer_alloc and
3075 silc_buffer_free functions inline functions.
3077 * Disabled command flooding detection support until it's fixed so
3078 that it accepts commands in but does not execute them more than once
3081 * Added silc_net_localhost(), to return local hostname, into
3082 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3083 that must be initialized before calling silc_client_init.
3085 * Added new function: silc_server_send_notify_on_channels to send
3086 notify messages to all channels client has joined. It is assured
3087 that the message is sent only once per client.
3089 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3090 lib/silcutil/silcutil.[ch] as silc_format function. The new
3091 function is generic and is used by server as well, not only by
3092 the logging routines.
3094 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3095 the provided version string was not acceptable. Added new function:
3096 silc_ske_check_version into lib/silcske/silcske.h. The function
3097 must be implemented by the application (client or server) and it
3098 does not reside in the SKE library. The function checks the version
3099 string remote end sent.
3101 * Added back pointers (to opaque context and to SilcSocketConnection)
3102 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3104 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3105 duplicate packet context structure.
3107 * Changed `notify' client operation to send same arguments as client
3108 receives from server except for ID's. ID's are mapped to correct
3109 ID entry and that is returned. Also, if channel entry is not sent
3110 by server but the notify is for channel the channel entry is sent
3111 to application (otherwise application doesn't know that it is for
3112 channel (library gets it from packet's Destination ID)).
3114 * Added silc_client_remove_from_channels into client library to
3115 remove a client from all channels it has joined to. Used when
3116 received SIGNOFF notify from server. Added also new function
3117 silc_client_replace_from_channels to replace old ID entry with
3118 new ID entry on all channels. Used when received NICK_CHANGE
3121 * Fixed ID Cache list handling in silc_idlist_get_client in
3122 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3123 to get (or query) client by ID.
3125 * Updated TODO list.
3127 * Added connection authentication status message defined by the
3128 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3129 support for these into the code in client and server side.
3131 * Added generic function silc_client_send_command to send any command
3132 with variable argument list. Application should use this function
3133 to send commands if the command functions provided by the library
3134 does not suite for the application's user interface needs.
3136 * Added new `failure' client operation. Application is notified about
3137 received failure packet if client is executing a protocol. In this
3138 case the protocol's execution has failed.
3140 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3141 is required by the protocol.
3143 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3144 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3147 * Added status flag to SilcSKE object to indicate realtime status
3148 of the SKE protocol.
3150 * Application receives now exactly same command reply arguments as
3151 the library receives from server. However, if ID is received the
3152 corresponding ID entry is returned to the application (eg. Client
3153 ID is mapped to correct SilcClientEntry entry and that is returned).
3154 Changed command_reply client operation due to this change.
3156 * Changed all ID's in commands and in command replys as ID Payloads.
3157 Change affected both client and server side codes.
3159 All ID's sent in SILC network (with execption of ID's in SILC
3160 Packet header) are sent in ID Payload to support variable length
3163 * Server now notifies nick changes and notifies all clients on
3164 the channels about the new nickname (about the new Client ID,
3167 * Implemented CMODE command to change channel modes. Supports all
3168 channel modes defined by the protocol specs except ban and invite
3169 lists. (Also, private channel key mode is supported but support for
3170 setting private channel key in client is missing, thus, this mode
3171 has no effect on client side (except that server requires that the
3172 client uses private channel key and normal channel traffic does not
3175 Also, invite mode works per se, but INVITE command does not work
3176 yet correctly, so you can set channel as invite only channel but
3177 inviting clients to the channel does not work (it is yet to be
3178 thought what's the best way to do it).
3180 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3181 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3182 Implemented CUMODE command to change user's mode on the channel.
3183 Supports all modes defined by the protocol specs.
3185 * Added NAMES command reply to return users modes on the channel.
3187 * Removed unnecessary and slow ciphers from lib/silccrypt.
3189 * Set SO_KEEPALIVE option to connection sockets by default.
3191 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3193 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3194 redefined the Notify Payload into protocol specs.
3196 * Added silc_id_payload_parse_id to get ID directly from raw
3199 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3202 accept searching by Client ID as well.
3204 * Added support for LEAVE and SIGNOFF notify types in client library.
3206 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3207 to parse ID Payload from raw data.
3209 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Added flags parameter into silc_ske_assemble_security_properties
3212 function in lib/silcske/silcske.[ch].
3214 * Changed notify client operation to fit better for notify messages
3215 sent by server. The notify payload received from server is now
3216 passed to the application (after parsing it to SilcNotifyPayload).
3217 It is application's responsibility to retrieve the arguments
3218 from the payload and show the message the way it wants. The message
3219 sent by server is implementation specific.
3221 * Changed public keys to comply with the protocol specification.
3222 Old public keys are not supported anymore and are not compatible.
3224 * Removed nickname from Channel Payload as the latest draft removed
3225 it. The client must resolve the nickname from the NAMES command
3226 reply received when it joined the channel.
3228 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3230 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3232 * Fixed some errors in protocol specification drafts.
3234 * Created lib/silccore/silcnotify.c to implement Notify Payload
3235 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3236 generic payloads described by protocol specifications. The file
3237 includes implementations for ID Payload and Argument Payload.
3239 * Changed Command Payload implementation to use the new Argument
3240 Payload. Changed command_xxxx_payload to command_payload_xxxx
3241 to comply with SILC coding conventions.
3243 * Added suppport for Argument Payload handling in Notify Payload
3244 implementation as protocol requires it. Added the new support
3245 into server and client lib as well.
3247 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Added support for multiple nicknames on same channel. [n] is
3250 added locally to the nickname if there are more than one same
3251 nicknames on the channel.
3253 * Server now sends all nicknames that matched WHOIS request.
3254 Client also shows the list received from server.
3256 * Added TOPIC command to client side. User can now set and show
3257 current topic on channel.
3259 * Added MOTD command to client and server. Also, server sends the
3260 motd when client connects to the server.
3262 * Changed version strings to comply ISO 8601.
3264 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3266 * Fixed protocol error handling in client library. It should now
3267 cope even if the SKE fails for some reason.
3269 * Made new protocol specification drafts for submitting to IETF.
3271 * Implemented TOPIC command to server in silcd/command.c.
3273 * Added two new notify types into lib/silccore/silcnotify.h:
3274 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3275 notify nickname change and topic setting/change on a channel.
3277 * API change of command_reply operation in client library. The
3278 application gets now the status type received from server as well.
3280 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3284 * Cras fixed and optimized the packet handling even further and
3285 it should work now. Minor change to the prototype of function
3286 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3288 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3290 * Added new function into lib/silcutil/silcschedule.[ch]:
3291 silc_schedule_with_fd to select() a specified fd. The function
3292 returns after timeout expires or data arrives or goes. The
3293 function is used by packet routines to wait that all data is
3294 received from network.
3296 * Fixed data reading from network in lib/silccore/silcpacket.c.
3297 The code now assures that all data is read from the fd and then
3298 continues packet processing. This was a bug fix since the code
3299 used to drop some data in some circumstances.
3301 * Added new function into lib/silcclient/client.[ch]:
3302 silc_client_start_key_exchange to start key exchange after
3303 connection has been established to server. The code internally
3304 now uses this funtion but its main purpose was to provide it
3305 for applications that perform their own connecting. After
3306 application has created a connection it merely calls this
3307 function to start the key exchange between client and server.
3308 The library takes care of everything else after that.
3310 Updated also lib/silcclient/README to explain the usage of
3313 * Do not send to application information that connection has
3314 been established. Application gets notified it by connect
3317 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Applied cras's patch to add silc_schedule_one function. The
3320 function runs scheduler once and returns.
3322 * Fixed the scheduler after cras messed it up. The timeout
3323 handling works now as it's supposed to work.
3325 * Added into lib/silccore/ silcnotify.h to include notify
3326 message types support. Changed silc_server_send_notify*
3327 functions, in server.[ch], to support those new notify types.
3328 Added the support for the notify types into client library,
3329 as well. Added new notify client operation into ops.h in
3332 * Changed silc_server_packet_send_to_channel to send normal
3333 packets instead of just channel message packets. The function
3334 is now used to send the notify packets to channels. It is not
3335 used to send channel message packets anymore, as server never
3338 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3339 va_arg()s as it seems to require it nowadays. I guess, if SILC
3340 is compiled with older va_arg() the new code should work anyway.
3342 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Splitted core library. Core library (lib/silccore) includes
3345 now only SILC protocol specific core (and common) components.
3346 Created new utility library (lib/silcutil) that includes more
3347 generic purpose stuff. The stuff for util library was taken
3348 from the old core library. This was minor and easy split.
3350 * Created SILC Client Library (lib/silcclient) that includes
3351 implementation of the SILC client without user interface. This
3352 was major move from silc/ directory. The code has been changed
3353 so that it is transparent towards the user interface. The
3354 silc/ directory includes now the same user interface as before
3355 and it uses the new client library. Read lib/silcclient/README.
3356 Basicly, the client library performs everything else related
3357 to SILC except user interface handling. Also, configuration
3358 files are considered to be part of user interface and library
3359 does not handle them.
3361 This change also changed a lot of structures, function naming etc.
3362 Most important change was that SilcClientWindow object was
3363 renamed to SilcClientConnection in the client library. Created
3364 also new file lib/silcclient/ops.h. Also added new files
3365 silc/local_command.[ch] and silc/client_ops.[ch].
3367 All these changes were made to make it easier for user interface
3368 designers to create what ever user interface for the SILC client
3371 It is also expected that the server will be moved to lib
3372 directory as well and SILC Server Library will be created;
3373 sometimes in the future.
3375 * Removed Local commands from lib/silccore/silccommand.h as
3376 they are application specific and new client library does not
3377 handle any of those anymore.
3379 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3380 old client implementation in silc/.
3382 * Added support for callback functions in SILC_LOG_* macros.
3383 Application can now set its own callbacks that will be called
3384 instead of using the default functions that will always print
3385 the debug messages to stderr (or stdout). Also, debugging can
3386 now be disabled by setting silc_debug to FALSE and re-enabled by
3387 setting it to TRUE. Note, that logging will still work even
3388 if debugging is disabled.
3390 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3391 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3392 silc_log_reset_debug_callbacks.
3394 * To enable debugging in silc client one must give now -d
3395 option on command line.
3397 * Changed silc_schedule_init to automatically allocate task queues
3398 if they are not allocated before calling it.
3400 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Added GMP 3.1 into math library.
3404 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3407 a channel in SILC network. The packet is used by servers and
3408 routers to notify other routers that user has left a channel.
3409 This little feature was missing until now. Added the feature
3410 to protocol specification as well.
3412 Added functions: silc_server_send_remove_channel_user and
3413 silc_server_remove_channel_user into server.[ch].
3415 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3416 lib/silccore/silcpacket.h. However, they are not implemented
3419 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Fixed joining to a channel and sending channel messages
3422 between server and router. The channel message sending should
3423 now work inside a cell.
3425 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Fixed the private message sending between server and router.
3428 The private message sending should now work inside a cell.
3430 * Added silc_server_replace_id into server.[ch] to replace
3431 existing ID in the SILC network.
3433 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3434 and silc_idlist_replace_server_id into idlist.[ch] in server.
3436 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3438 * Fixed the server to server connections. Server can again now
3439 connect to router. Router to router connections probably does
3442 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3444 * Added dynamic protocol registering support. Now protocols can
3445 registered and unregistered on the fly. Patch by cras.
3447 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Added lib/contrib directory to hold routines that some platforms
3450 don't have but are needed by SILC.
3452 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3453 into lin/contrib to provide getopt() and getopt_long() for
3454 those who don't have it.
3456 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Added AWAY command to client. When away message is set and
3459 client receives a private message packet the client automatically
3460 replies to the sender with the away message.
3462 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3463 bug seemed to be the cause of recent problems when compiling
3466 * Added version detection support to SKE protocol specification
3467 and added the new changes to the SKE implementation as well.
3468 There were other minor changes in the SKE protocol as well.
3470 Many changes in lib/silcske/silcske.[ch] and in
3471 lib/silcske/payload.[ch].
3473 * Added ^U functionality, clear input line. Patch from cras.
3475 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3477 * Mainly small bugfixes on core library. Fixed some debugging
3478 logging and buffer overflow in silclog.c.
3480 * Updated config.sub and config.guess on the distribution tree.
3482 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Added command lagging support in server. Client may execute
3485 commands now only once in two seconds.
3487 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Optimized packet reception. MAC computation and checking is now
3490 also more optimized. A lot previously duplicated code is now
3491 used as generic by both client and server.
3493 * Fixed key pair generation in clientutil.c
3495 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * Added into lib/silccore/silcbufutil.[ch] new function;
3498 silc_buffer_realloc.
3500 * Moved generic packet sending/encryption functions to
3501 lib/silccore/silcpacket.[ch] from client and server. Some
3502 rewriting of the functions.
3504 * Moved all generic packet reception/decryption functions to
3505 lib/silccore/silcpacket.[ch] from client and server. The
3506 packet processing is now much cleaner in both client and server.
3507 These were major changes in both client and server.
3509 * Created many common functions in server to do packet sending.
3510 Previously code were duplicated a lot, this has been removed
3513 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3515 * Rewrote major parts of the ID cache system. Don't know
3516 whether it is better now or not but at least the API is more
3519 * Major rewrite on ID cache stuff on client because of the ID
3520 cache API changes. Added idlist.c to client.
3522 * Also major rewrite on ID cache stuff on server as well.
3523 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3524 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3525 in hand, instead they are all put into the ID cache system now.
3526 All server_idlist_* routines uses ID cache now instead of
3527 traversing its own lists (those lists does not exist anymore).
3528 SilcIDList though still exists. Also, SilcXXXEntry's are
3531 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3533 * Finally made the SKE implementation compliant to the protocol
3534 specification. All mp integers are now binary encoded as
3535 opposed being HEX encoded.
3537 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3540 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3541 functions: silc_[encode/decode]_pem. Also added function
3542 silc_encode_pem_file to PEM encode with newlines ('\n') for
3545 * SILC public keys are now encoded either PEM or binary. Same
3546 option is for private keys as well. By default private keys
3547 are binary encoded and public keys PEM encoded. Silly HEX
3548 encoding were removed.
3550 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3551 function to create fingerprints.
3553 * Fixed a bug in SHA1; does not change the original data anymore.
3555 * Partly implemented INFO command on client and server side.
3556 Fixed CLEAR command. Changes to SERVER command; show current
3557 server(s) when giving command without arguments. Added
3558 VERSION command to client.
3560 * Added check to server that unregistered connections cannot
3561 execute commands (unless it is specificly allowed).
3563 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3565 * Fixed screen refresh.
3567 * Fixed channel joining bug from client. On some circumstances
3568 client tried to join to a channel it had already joined.
3570 * Added public key verification process into client's protocol.c.
3571 The client now verifies the public key from user and saves
3572 it into ~./silc/serverkeys/ directory.
3574 Added into: clientutil.[ch]: silc_client_verify_server_key.
3576 * Changed SKE protocol's silc_ske_initiator_finish function
3577 to accept callback function that verifies the received public
3578 key. Removed old silc_ske_verify_public_key function.
3580 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3583 silc_pkcs_private_key[_data]_set.
3585 * Made the password and public authentication more cleaner in
3586 server's protocol.c.
3588 * Removed historic and obsolete protocol `channel_auth' from
3589 both client and server.
3591 * Removed wrong way of sending command status messages from
3592 server to client in server's command.c. The old way violated
3593 protocol specification.
3595 Changes to silccore/silccommand.[ch]: removed
3596 silc_command_encode_status_payload -> not needed anymore,
3597 changed silc_command_encode_payload_va to accept extra
3598 argument on variable argument list. The argument type must
3599 now be provided to the function. Also, added new function:
3600 silc_command_encode_reply_payload_va which is same as
3601 normal command_encode_payload_va except command status type
3602 is provided as extra argument.
3604 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Added ~./silc directory handling. The directory includes the
3607 public and private keys for the client.
3609 Added silc_client_check_silc_dir, silc_client_create_identifier
3610 and silc_client_load_keys.
3612 * Implemented SILC protocol compliant public key. Added public
3613 and private key saving to and loading from files.
3615 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3616 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3617 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3618 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3619 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3621 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3622 silc_pkcs_load_[public/private]_key.
3624 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3626 * Added silc_server_get_route (route.[ch]) to get connection
3627 data for the fastest route for given ID.
3629 * Implemented INVITE command on client and server. The command
3630 were re-defined in the SILC Protocol Specification and the
3631 implementation now complies with the specification.
3633 * Implemented PING command on client and server.
3635 * Implemented NAMES command on client and server. The server side
3636 supports currently only normal server not router server yet.
3637 Some changes to NAMES definition in SILC protocol specification.
3639 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * Implemented LEAVE command on client and server.
3643 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3644 again. This change was made to the protocol as well. Server
3645 should not violate the protocol specification anymore.
3647 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3649 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3650 was tested. SOCKS4 was not but should work anyway.
