3 * silc_idcache_purge_by_context deletes the entry now by context
4 as it is supposed to do. Affected file lib/silccore/idcache.c.
6 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
7 client is not anymore valid (WHOWAS givens the info) and not
8 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
10 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
12 * Removed the `data' and `data_len' arguments from the ID Cache
13 interfaces and added `name' argument. ID Cache does not handle
14 anymore the binary data only a names associated with given ID.
16 * When hashing a Client ID with silc_hash_id the entire ID is
17 not hashed anymore, instead only the hash of the Client ID is
18 hashed. This way we can access the Client ID from the cache
19 with Client ID but with the hash of the ID (which is a hash of
20 the nickname) as well without any difference in performance.
22 Added also silc_idcache_find_by_id_one_ext to do one on one
23 searching when we have the actual ID. Added also function
24 silc_hash_client_id_compare. The affected files are
25 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
27 * When hashing the name associated with a ID it is always done
28 in lowercase. This way we can access the cache without worrying
29 about case-sensitivity, even though, for example nicknames are
32 * Fixed a bug in server with channel message sending. It put
33 wrong ID type as destination ID. The affected file
36 * silc_idcache_del_by_context now deletes from all hash tables
37 by context. Affected file lib/silccore/idcache.c.
39 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
41 * Changed the client library to use the new ID Cache interface.
42 Changes around the source tree.
44 * Added silc_hash_table_rehash_ext to rehash with specific
45 hash function. Affected file lib/silcutil/silchashtable.[ch].
47 * Added silc_hash_string_compare to compare two strings in the
48 hash table. Affected file lib/silcutil/silcutil.[ch].
50 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
52 * Added new function silc_idcache_del_by_context into the
53 lib/silccore/idcache.[ch].
55 * Changed the server's ID list routines to use the new ID Cache
56 interface. Changes around the source tree.
58 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
60 * Added silc_hash_table_del[_by_context]_ext functions in to the
61 lib/silcutil/silchashtable.[ch].
63 Removed silc_hash_table_find_all* routines and added new
64 silc_hash_table_find_foreach to replace them.
66 Added silc_hash_table_replace_ext function as extended
67 replacing function. Separated the simple hash table interface
68 from the extended hash table interface in the file
69 lib/silcutil/silchashtable.h.
71 * Fixed minor bugs and changed it to use some of the new
72 hash table functions in lib/silccore/idcache.c
74 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
76 * Added new function silc_hash_table_find_all to return all keys
77 in the hash table by the specified key. As the hash table is
78 collision resistant it also makes it possible to have several
79 duplicate keys in the hash table. This function may be used to
80 find all of the keys from the hash.
82 Added user_context arguments to the SilcHashFunction,
83 SilcHashCompare and SilcHashDestructor to deliver user specified
86 Added new fuctions silc_hash_table_find[_all]_ext to do
87 extended lookup with specified hash and compare functions and
88 specified user contexts.
90 Added new function silc_hash_table_add_ext to add the key
91 with specified hash function and user context.
93 Added new function silc_hash_table_foreach to traverse all
94 entrys in the hash table. Added SilcHashForeach callback
97 Added new function silc_hash_table_del_by_context to delete
98 the entry only if the context associated with the key matches.
100 Affected files are lib/silcutil/silchashtable.[ch].
102 * Removed silc_hash_[server/client/channel]_id and added just
103 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
104 silc_hash_id_compare to compare two ID's using as the hash table
105 comparison function. Added also silc_hash_data to hash
106 binary data and silc_hash_data_compare to compare it.
108 * Removed silc_idlist_find_client_by_hash as it is not needed
109 anymore. Affected file silcd/idlist.[ch].
111 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
112 to use internally the SilcHashTable. The new ID Cache is a lot
113 faster than the old one. Some of the ID Cache interface was also
114 rewritten and obsolete and stupid functions were removed.
116 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
118 * Added entry_count field to the SilcHashTable to keep the number
119 of the entries in the table. Implemented the function
120 silc_hash_table_rehash. Added new function
121 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
123 Fixed a minor bug in silc_hash_table_free.
125 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
126 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
127 into the lib/silcutil/silcutil.[ch].
129 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
131 * Implemented a collision resistant hash table into the
132 lib/silcutil/silchashtable[ch]. See the header and the source
133 for the SilcHashTable API.
135 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
137 * Merged dotconf version 1.0.2 into lib/dotconf.
139 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Do not compile anything in lib/silcsim/* if the SIM support
142 is not enabled. The tree should now compile without problems
145 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
147 * Compiled the SILC under cygwin. Compiled and tested briefly
148 without problems. More tests needed. The SIMs didn't compile
151 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
153 * Fixed possible crash in silc_get_username in the
154 lib/silcutil/silcutil.c.
156 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
158 * Fixed a va_arg in silc/client_ops.c.
160 * Oops, RC5 routines were named AES and caused some problems
161 when not using SIM's. Affected file lib/silccrypt/rc5.c.
163 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
165 * Added new SilcIDIP structure into the lib/silccore/id.h and
166 replaced the old `ip' fields from all SILC ID's to that type.
167 This is a step towards IPv6 support.
169 The silc_id_get_len takes now the ID as an extra argument.
170 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
171 both IPv4 and IPv6 based ID's.
173 The affected files are lib/silccore/id.[ch] and other files
174 around the tree using these routines.
176 * Removed the ID length arguments in server from various
177 silc_server_send_notify_* routines -> they are not needed
180 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
182 * Fixed memory leak in silc_encode_pem_file in the file
183 lib/silcutil/silcutil.c.
185 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
187 * Check minor version as well in the SKE. Affected files are
188 silcd/protocol.c and lib/silcclient/protocol.c.
190 * Added --identifier option to the server so that an identifier
191 can be when creating the public key for the server. Affected
192 file is silcd/silcd.c.
194 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
195 lib/silccrypt/silcpkcs.c.
197 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
199 * Register default ciphers and stuff when using -C option with
200 the server. Affected file sildc/silcd.c.
202 * Put back the servers public key filename format, it is better
203 than the new one. For now, the client keys are saved with the
204 new filename format. The affected file silc/client_ops.c.
206 * Implemented the Cipher API for the rest of the ciphers that
207 did not implement it or implemented it the wrong way.
209 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
211 * Register default ciphers and stuff when using the -S option
212 in the client. Affected file silc/silc.c. Same also when
213 creating new key pair with -C option.
215 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
217 * Fixed the silc_verify_public_key client operation function to
218 save the public keys differently. The fingerprint is now
219 used as filename and not the hostname. This way also the
220 client keys are saved uniquely and not with hostnames. The
221 affected file is silc/client_ops.c.
223 * Trimmed the silc_hash_fingerprint function to remove extra
224 whitespaces from the end of the fingerprint. The affected
225 file is lib/silccrypt/silchash.c.
229 * Added silc_cipher_register_default function to register all
230 default ciphers. It can be used when configuration files
231 does not exist and the application does not want any specific
232 ciphers in any specific order.
234 The SilcDList is now used as silc_cipher_list dynamically
235 allocated cipher list. Removed the static list all together
236 and now all ciphers must be allocated to the dynamic list.
237 The silc_cipher_alloc routine was changed to check only the
240 All silc_cipher_* routines that used to return int returns
243 The affected files lib/silccrypt/silccrypt.[ch].
245 * The same thing was done to silc_hash_* as for silc_cipher_*
246 routines. Affected files lib/silccrypt/silchash.[ch].
248 * The same thing was done to silc_pkcs_* as for silc_cipher_*
249 routines. Affected files lib/silccrypt/silcpkcs.[ch].
250 Added also silc_pkcs_[un]register[_default] functions.
251 Removed the data_context from the PKCS API.
253 * Added silc_hmac_register_default function to register default
254 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
255 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
256 to unregister all hmacs at once.
258 * Register the default ciphers, hash functions, PKCSs and HMACs
259 if client's configuration file does not exist. The affected
262 * The client did not load the hash functions from the SIM
263 modules at all. Added support for this. Affected file is
266 * When decoding public key with silc_pkcs_public_key_decode, check
267 the supported algorithm only if PKCS are registered. Affected
268 file lib/silccrypt/silcpkcs.c. The same was done with the
269 silc_pkcs_private_key_decode.
271 * Fixed the SILC List routines to keep the list always in order.
272 It used to change the list's order when traversing the list but
273 not it preserves the order. Affected file lib/trq/silclist.h.
275 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * Added the client library to use the SilcSocketConnection's
278 reference counter (by silc_socket_dup) to prevent the bug that
279 the socket object may be freed underneath async operation.
281 * The name resolv library checking fixes in the configure.in.pre.
284 * Created new version of the protocol drafts for future
285 development. The -03 drafts are the ones that will be changed
286 in the trunk now and the -02 will remain as they are.
288 * Send list of CUMODE notifys to the router when announcing
289 the channel users to the router. Affected file silcd/server.c.
290 If the router receiving channel founder CUMODE for a channel
291 that already has channel founder it will send CUMODE notify
292 to the sender to remove the channel founder rights from the
293 announced client. Affected file silcd/packet_receive.c.
295 * The CUMODE notify may now use Server ID as well as the entity
296 who changes the mode. Updated protocool specs.
298 * Updated INSTALL and README files.
300 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
302 * New web pages in the http://silc.pspt.fi. The pages was
307 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
309 * Implemented the [DenyConnectin] config section in the server.
310 Added silc_server_config_denied_conn to check whether incoming
311 connection is denied. Affected file silcd/serverconfig.[ch].
313 * Do not check the ports when checking the incoming configuration
314 data if the port is 0, meaning any. Affected file is
315 silcd/serverconfig.c.
317 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
319 * Fixed buffer overflow in silc_string_compare in the file
320 lib/silcutil/silcutil.c.
322 * Fixed double free in silc_server_command_leave in the file
325 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
327 * Fixed the version checking in the server. Affected file is
330 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
332 * Fixed the configuration data fetching when accepting new
333 connections in the server. Affected file silcd/server.c.
335 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
337 * Added `sender_entry' argument to the function
338 silc_server_packet_relay_to_channel so that we can check
339 whether some destination actually belongs to the same route
340 the sender belongs (ie, we must not resend the packet to the
341 sender). Affected file silcd/packet_send.[ch].
343 * Added `servername' field to the SilcClientEntry in the server
344 to hold the name of the server where client is from. Affected
345 file is silcd/idlist.h.
347 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
349 * Moved the channel message encrypting in the router betwen
350 router connections from silc_server_channel_message to the
351 silc_server_packet_relay_to_channel since we want to check
352 whether we have anybody channel before encrypting anything.
353 Affected files silcd/packet_[receive/send].c.
355 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
357 * Fixed the [AdminConnection] server config section to support
358 multiple entries. Affected file silcd/serverconfig.c.
360 * Added support into the server to check the validity of the
361 incoming connection before executing any KE or authentication
364 * The connection configuration is now saved to the KE and
365 connection auth protocol contexts and not fetched anymore in
366 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
368 * The local hosts listenning address and port is also resolved
369 now when starting the server. We want to have the socket object
370 to include the real address and port for the listener. Added
371 new function silc_net_check_local_by_sock into the files
372 lib/silcutil/silcnet.[ch].
374 * Fixed a broadcast bug in server -> do not broadcast if we
377 * Fixed a routing bug. Do not route broadcast packets ever.
378 Broadcast packets must be processed always and not routed since
379 they may be destined to some other host than yourself and thus
380 would get routed without no good reason. Affected file is
383 * Added function silc_server_config_is_primary_route to check
384 whether primary router connection has been configured (a router
385 configuration that we are initiating). If there is not, we
386 will assume that there is only two routers in the SILC network
387 and we will use the incoming router connection as our primary
388 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
390 * Changed the order of the broadcasting. Broadcast _after_ the
391 packet has been processed not before. Affected file is
394 * Fixed a [ClientConnection] parsing bug. The port was never
395 parsed correctly thus resulting to port 0. Affected file
396 silcd/serverconfig.c.
398 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
399 argument and did not set the broadcast packet flag. Affected
400 file silcd/packet_send.c. Fixed same bug in the function
401 silc_server_send_notify as well.
403 * If we receive NEW_ID packet for our own ID in the server, ignore
406 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
410 * Removed the nickname from the Private Message Payload.
411 Updated the code and the protocol specs.
413 * Updated protocol specs for submitting to the IETF.
415 * Tweaked the Random Number Generator a bit. Affected file
416 lib/silccrypt/silcrng.c. Exported a new function
417 silc_rng_[global]_add_noise which can be used to add more
420 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
422 * Do not parse packets with different timeout when protocol
423 is active -> may cause problem with rekey. Affected file
426 * When server receives signoff notify it must not create
427 new channel key if the client is on any channels since the
428 sender of the signoff notify will create it.
430 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
432 * Added printing of error messages during SKE protocol from the
433 failure packet sent by server during SKE. Affected file
436 * Removed the client's failure_callback handling with timeout
437 and handle it immediately when received.
439 * The SKE library returned wrong type in SUCCESS and FAILURE
440 packets. They must be 32 bit MSB not 16 bit MSB.
442 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
444 * Ok, rewrote the logic of the re-key and now it seems to work.
445 I tested it on high traffic with frequent re-keys without
446 problems. Added hmac_receive (and renamed hmac to hmac_send)
447 in SilcClientConnection in lib/silcclient/client.h and
448 in SilcIDListData in silcd/idlist.h. Also, removed the
449 SilcPacketParserContext's cipher and hmac fields as they are
450 not needed anymore and actually caused some problems when
451 the ciphers and hmac's changed underneath the packet parser.
453 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
455 * If re-key protocol is active then process the incoming packets
456 synchronously since we must assure that icoming packets encrypted
457 with the old key is processed before the new keys is set to
458 use. This is true other packets than for REKEY packets.
459 Affected file silcd/server.c. The same was done to client library
460 as well, affected file lib/silcclient/client.c.
462 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
464 * Fixed bug in client and server to accept the force send if
465 the packet is send from silc_[server/client]_packet_process
466 function. Otherwise the packets are never delivered, oops.
468 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
470 * Disable force sending of packets when REKEY protocol is active.
471 We must assure that no packet is sent directly when rekey is
472 performed. All packets must be sent through packet queue.
473 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
474 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
475 function is silc_[server/client]_packet_send_real to check
478 * Replaced the SIM paths from example config files to
479 /usr/local/modules. Also, make install creates now
480 /usr/local/silc/logs directory to hold all the SILC server
483 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
485 * Made the configure.in.pre work on Solaris. Patch by salo.
487 * Made all ciphers compatible with non-x86 machines. Defined
488 CBC mode macros into lib/silccrypt/ciphers_def.h.
490 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
492 * Fixed the make install.
494 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
496 * When MAC computation fails the silc_packet_decrypt returned 0
497 even though it was supposed to return -1. Fixed this. The
498 affected file is lib/silccore/silcpacket.c.
500 * Do not replace the config files in /etc/silc (in make install)
501 if they already exist. Affected file ./Makefile.am.
503 * Do not send re-key packets immediately but through packet queue.
504 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
506 * Changed silc_net_check_host_by_sock to return FALSE if the
507 IP/DNS could not be resolved. Though, it returns the IP address
508 now even if it could not resolve it (but returns also FALSE).
509 Affected file lib/silcutil/silcnet.[ch].
511 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
513 * Added silc_pkcs_decode_identifier to decode the public key's
514 identifier. Affected file lib/silccrypt/silpkcs.[ch].
515 Added also silc_pkcs_free_identifier. Added also new context
516 SilcPublicKeyIdentifier.
518 * Added -S option to the silc client. It is used to dump the
519 contents of the specified public key file.
521 * Changed the PKCS api to return the public key length when
522 setting the public key.
524 * Fixed a fatal bug in the public and private key file loading.
525 Affected file lib/silccrypt/silcpkcs.c.
527 * Execute the packet parsing for client with zero (0) timeout
528 if the protocol is active. Affected file silcd/server.c.
530 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Made the key generation options to the silcd program. Added
533 -C option, equivalent to client's option.
535 * Added new [ServerKeys] config section to the server. It
536 configures the server's public and private key.
538 * Defined generic Public Key Payload into the protocol
539 specification to send specific type of public keys and
542 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
543 public key or certificate.
545 * Implemented the GETKEY command to the server and to the
546 client library and on user interface.
548 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
550 * Made preliminary `make install' work.
552 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
554 * Added SilcServerRekey context into silcd/idlist.h.
556 * Added the PFS support as defined in the specification to the
557 SKE protocol. Affected files lib/silcske/*.c.
559 * Added `ske_group' field to the SilcServerRekey context to hold
560 the number of the SKE group that is used with PFS in re-key.

567 state of the protocol. Affected file is
568 lib/silccore/silcprotocol.[ch].
570 * Added the re-key support with and without PFS to the client
571 library. Re-key is performed once in an hour, by default.
573 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
574 Added silc_client_rekey_callback and silc_client_rekey_final.
575 Affected files are lib/silcclient/protocol.[ch] and
576 lib/silcclient/client.[ch].
578 * Removed the `hmac_key' and `hmac_key_len' fields from the
579 SilcClientConnection structure; not needed. Affected file is
580 lib/silcclient/client.h.
584 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
586 * Do not ask whether user wants to use the negotiated private key
587 for private messages, just use it. Affected file is
588 silc/local_command.c.
590 * Added `send_enc_key' and `enc_key_len' fields to the
591 SilcIDListData structure since they are needed in the re-key
592 phase. Affected file is silcd/idlist.[ch].
594 * Implemented the simple re-key protocol into the server.
595 Affected files silcd/server.c and silcd/protocol.[ch]. The
596 re-key will be performed once in an hour, by default.
598 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
599 Added silc_server_rekey, silc_server_rekey_callback and
600 silc_server_rekey_final.
602 * Removed Tunneled flag from the protocol. Updated the code
603 and the specifications.
605 * Adde `pfs' field to the SilcIDListData to indicate whether
606 the PFS is to be performed in the re-key. Affected file is
609 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
611 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
612 int64 of at least the xintXX size. If void * is less that 4
613 bytes uint32 * will be used. Defined bool as boolean.
615 * Changed _ALL_ unsigned long and unsigned int to uint32,
616 unsgined short to uint16 in the source tree.
618 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
619 not handle clients that has entry->data.registered == FALSE.
620 They are not in the network anymore. Affected file is
623 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
625 * Implemented the sending of the SERVER_SIGNOFF notify in the
626 server. Affected file is silcd/server.c.
628 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
629 Added also silc_notify_payload_encode_args into the
630 lib/silccore/silcnotify.[ch].
632 * Implemented ther SERVER_SIGNOFF notify handling in the server.
633 Affected file silcd/packet_receive.c.
635 * Implemented the SERVER_SIGNOFF notify handling in the client
636 library. Affected file lib/silcclient/client_notify.c. Also,
637 implemnted the printing of the SERVER_SIGNOFF info to the
638 application. Affected file silc/client_ops.c.
640 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
641 if the deleting was successful. Affected file silcd/idlist.[ch].
643 * Added support for public key authentication in the connection
644 authentication protocol in the client library. Affected file
645 lib/silcclient/protocol.c.
647 * Changed the server's silc_idlist_get_clients_by_* interface
648 to support already allocated array so that new entries may be
649 added to pre-allocated array. Affected file silcd/idlist.[ch].
650 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
653 * All command reply functions in the server now calls the
654 pending command callback even if error occured. This way the
655 error will be delivered to the client as well. Affected files
656 silcd/command.c and silcd/command_reply.c.
658 * Fixed INFO command to return local server's info if no server
659 was provided. Affected file lib/silcclient/command.c.
661 * Removed RESTART command for good. Updated the code and the
664 * Rewrote parts of the task system. It is a bit simpler now.
665 Removed unsued task priorities. The affected files are
666 lib/silcutil/silctask.[ch].
668 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
670 * Moved the USERS printing from the library to the application.
671 Affected files lib/silcclient/command.c and silc/client_ops.c.
673 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
677 * Added channel key re-key support. The re-key is perfomed
678 only by the router and is done once in an hour. Added `rekey'
679 field to the SilcChannelEntry in the server. Affected files
680 silcd/server.c and silcd/idlist.h.
682 * Added silc_task_unregister_by_context into the file
683 lib/silcutil/silctask.[ch].
685 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
687 * Added SILC_UMODE_GONE mode to indicate when the client is not
688 present in the SILC network. Added also support to the local
689 command AWAY that will set this mode. Added support of showing
690 "xxx is gone" in WHOIS command. The USERS command shows the
693 * Fixed setting server and router operator privileges in the
694 server's UMODE command. Affected file silcd/command.c.
696 * Merged the SKE KE1 and KE2 payloads into one payload. The
697 new KE payload is equivalent to the old KE2 payload.
699 Cleaned up the SKE Start Payload parsing. It now uses the
700 simple buffer unformatting to do the parsing. A lot faster
703 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
704 to the SKE that is used to indicate whether both of the SKE
705 parties should perform authentication. By default only the
706 responder performs authentication. By setting this flag also
707 the initiator must do authentication. By default it is unset
708 since in normal SKE case, client to server connection, only
709 the responder should do authentication. When doing SKE between
710 two clients both should perform authentication. Updated the
711 code and the protocol specs.
713 * A little fix to IDENTIFY command in the server. Search the
714 client first by hash not nickname. Affected file is
717 * Fixed the silc_client_close_connection to support closing
718 the client to client connections wihtout deleting too much
719 data. Affected file lib/silcclient/client.c.
721 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
722 are received if protocol used to be active but is not anymore
723 the application would crash due to NULL pointer dereference.
724 Affected files silcd/server.c and lib/silcclient/client.c.
726 * Added `hash' field to the SilcClientConnection to include
727 the hash function negotiated in the SKE protocol.
729 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
730 to set the channel founder authentication data. A client can
731 claim the founder rights later by providing the authentication
732 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
733 This way the channel founder can regain the channel founder
734 privileges even it is left the channel. This works only on
735 local server and the client must be connected to the same
736 server to be able to regain the founder rights. Updated the
737 protocol specs accordingly.
739 Added support to the CMODE command in the client to set the
740 founder auth data. Read the README to see how to set it.
742 Added support to the CUMODE command to claim the founder
743 rights. Read the README to see how to do it.
745 Added support for the founder authentication to the Channel
746 Entry in the server. Affected file silcd/idlist.h.
748 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
749 server's CMODE command. Affected file silcd/command.c.
751 * Added the following new functions into lib/silccore/silcauth.[ch]:
752 silc_auth_get_method and silc_auth_get_data.
754 * The server now saves the remote hosts public key to the
755 SilcIDListData pointer. Affected file silcd/protocol.c.
757 * The normal server now does not remove the channel entry from
758 the cache if the founder authentication data is set. It used
759 to remove it if the founder was the last one on the channel on
760 the server and left the channel. The auth data is saved and
761 if the channel is re-joined later the old entry is used with
762 the old auth data. Affected files silcd/command_reply.c and
765 * Removed the `pkcs' field from the SilcIDListData structure
766 in the server; it is not used. Affected file silcd/idlist.h.
768 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Fixed packet processing on slow links. Partial packets were
771 never re-processed because the incoming data buffer was cleared
772 by the application. Application must not directly clear the
773 sock->inbuf, the packet processing routines handle it. Fixed
774 this in client library and in server.
776 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
778 * Fixed the WHOIS and IDENTIFY send reply function to really
779 check whether to send list or just one entry. Affected file
782 * Cleaned up the LEAVE command's channel key distribution. The
783 affected file silcd/command.c.
785 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
786 can enforce the channel mode as well. In that case the ID
787 includes the ID of the server. The code now enforces the
788 mode change if the router have different mode than the server.
790 * The notify client operation with CMODE_CHANGE notify can now
791 return NULL client_entry pointer if the CMODE was not changed
792 by client. Application must check for this.
794 * Added <Server ID> argument to INFO command to support server
795 info fetching by Server ID.
797 * Added silc_server_announce_get_channel_users to get assembled
798 packets of channel users of the specified channel. Affected
799 file silcd/server.[ch].
801 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
802 was freed underneath the ID Cache.
804 * Re-announce clients when the server received CHANNEL_CHANGE
805 notify from the router. Affected file silcd/packet_send.c.
807 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
810 crashed since it did not handle the fact that there is no cipher
811 called "3" and didn't check the error condition. Now fixed.
813 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
814 flag. It can be used to send message requests.
816 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
818 * Implemented the RESTART command in the client.
820 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
821 notice type messages. Added notice printing to the user
824 * The channel keys are not re-generated if the channel's mode
825 is PRIVKEY, ie private key on the channel exists. Affected
826 files silcd/server.c and silcd/command.c.
828 * Fixed a little bug in channel message delivery when channel
829 private keys are set in the server. Affected file is
832 * Changed the setting on channel->on_channel = TRUE from the
833 silc_client_save_channel_key to the JOIN command reply. The
834 key payload is not received if the private channel key is set.
835 Affected file lib/silcclient/command_reply.c and the
836 lib/silcclient/client_channel.c.
838 * When the CMODE_CHANGE notify is sent and the channel private
839 key mode is removed the channel key must be re-generated in
840 other cells as well. Added this support for the router in the
841 silcd/packet_receive.c.
843 * Added new local command NOTICE to send notice message on
844 channel. Affected file silc/local_command.[ch].
846 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
848 * Added new local command ME to the client. It is used to send
849 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
850 some action. Affected file silc/local_command.[ch].
852 * Changed channel_message and private_message client operations
853 to deliver the message flags to the application. Added also
854 the `flags' arguments to the silc_client_send_channel_message
855 and silc_client_send_private_message functions. Affected file
858 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
860 * Redefined the Private Message Payload to support private message
861 keys and to support the new private message flags. Updated
862 the protocol specs. Flags makes it possible to have for example
865 * Added new type SilcPrivateMessagePayload and defined an API
866 for it in the lib/silcclient/silcprivate.[ch].
868 * Tested private message private keys successfully. Tested the
869 private message key set, unset and list commands with the new
872 * Redefined the Channel Message Payload to include the channel
873 message flags (equal with private message flags) to support
874 for example CTCP style messages.
876 * Defined some of the message (for channel and private message)
877 flags. Updated the protocol specs and added the flags to the
878 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
880 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
882 * Added SilcKeyAgreementStatus type to the key agreement routines
883 to indicate the current status and error if one occured.
884 The status types are defined in the lib/silcclient/silcapi.h.
886 * Added new local command KEY that is used to set and unset private
887 keys for channels, set and unset private keys for private messages
888 with remote clients and to send key agreement requests and
889 negotiate the key agreement protocol with remote client. The
890 key agreement is supported only to negotiate private message keys,
891 it currently cannot be used to negotiate private keys for channels,
892 as it is not convenient for that purpose.
894 * Fixed a minor pending callback setting bug in the function
895 silc_client_get_client_by_id_resolve, now the function works.
896 Affected file lib/silcclient/idlist.c.
898 * Added function silc_net_get_local_port to get local bound
899 port by socket. Added to lib/silcutil/silcnet.[ch].
901 * Added `sockets' and `sockets_count' fields to the SilcClient
902 object. They hold the sockets of the listenning sockets in
903 the client. Listenning sockets may be for example the key
904 agreement server. Affected file lib/silcclient/client.[ch].
905 Added functions the silc_client_add_socket and the
906 silc_client_del_socket. They are exported to the application
909 * Added ~./silc/clientkeys to support other client's public keys.
911 * Renamed verify_server_key client operation to verify_public_key
912 and added one argument to indicate the type of the connection
913 (server, client etc.).
915 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
917 * Added silc_server_connection_auth_request to handle the
918 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
919 silcd/packet_receive.[ch].
921 * Added silc_server_send_connection_auth_request into the
922 silcd/packet_send.c to send the connection auth request packet.
924 * Cleaned up the silcd/protocol.c a bit and fixed some memory
927 * Fixed the public key authentication in responder side in the
928 server. The `auth_data' pointer includes the SilcPublicKey
929 not the path to the public key. Affected file silcd/protocol.c.
931 * Implemented the public key authentication in the initiator side
932 in the server. Affected file silcd/protocol.c.
934 * Removed the [RedirectClient] config section from the server
935 configuration. Is not needed and I don't want to implement it.
937 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
939 * Cleaned up the CMODE command in the server. It now works
940 correctly and supports all the modes defined in the protocol.
941 Affected file is silcd/command.c.
943 * Added `hmac_name' field to the SilcChannelEntry in the server
944 to hold the default HMAC of the channel. It can be set when
945 creating the channel (with JOIN command). Affected files
948 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
949 type to indicate the change of the current cipher and hmac
950 on the channel. Client can safely ignore the <cipher> argument
951 (if it chooses to do so) since the CHANNEL_KEY packet will
952 force the channel key change anyway. The <hmac> argument is
953 important since the client is responsible of setting the new
954 HMAC and the hmac key into use.
956 * Fixed the CMODE command in the client library as well.
958 * Tested CMODE command in router environment successfully.
960 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
962 * Show the version of the remote client (or server) when connecting
963 to the server. It is logged to the log file. Affected file
966 * Fixed the KILLED notify handling in the client library. The
967 client must be removed from all channels when receiving the
970 Also, do not remove the client entry when giving the KILL
971 command but when the KILLED notify is received.
973 * Removed silc_idlist_find_client_by_nickname from the server.
974 Not needed anymore. Affected files silcd/idlist.[ch].
976 * Implemented the CHANNEL_CHANGE notify type handling to the
977 server. Affected file silcd/server.c.
981 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
983 * Added silc_server_send_notify_invite to send the INVITE
984 notify between routers.
986 * Implemented the INVITE command correctly to the server.
988 * Implemented the INVITE notify type handling in the server.
990 * Implemented the INVITE command to the client library and on the
993 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Added function silc_server_get_client_resolve to find the
996 client entry by ID from all ID lists and then resolve it
997 (using WHOIS) if it cannot be found. Affected file is
1000 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1002 * Implemented the BAN command to the client library.
1004 * The JOIN command in the server now checks the invite list
1007 * Changed the silc_command_reply_payload_encode_va and the
1008 silc_command_payload_encode_va to support that if argument is
1009 NULL it ignores and checks the next argument. Affected file
1010 lib/silccore/silccommand.c.
1012 * Added silc_server_send_notify_ban to send the BAN notify
1013 type between routers.
1015 * Chaned the silc_notify_payload_encode to support that if
1016 argument is NULL it ignores and checks the next argument.
1017 Affected file lib/silccore/silcnotify.c.
1019 * Tested ban lists in router environment successfully.
1021 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * Implemented BAN command to the server, in silcd/command.[ch].
1025 * Removed the BAN and INVITE_LIST modes from the CMODE command
1028 * Added function silc_string_match to regex match two strings.
1029 Affected files lib/silcutil/silcutil.[ch].
1031 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1033 * Redefined parts of the SilcChannelEntry in the server to support
1034 the new ban and invite lists.
1036 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1038 * Redefined the INVITE command. The same command can be used to
1039 invite individuals to the channel but also to manage the invite
1040 list of the channel (to add to and remove from the invite list).
1041 Updated the protocol specs.
1043 * Added new command SILC_COMMAND_BAN that can be used to manage
1044 the ban list of the channel. Updated the protocol specs.
1046 * Removed the channel modes: the SILC_CMODE_BAN and the
1047 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1048 in the CMODE command. The equivalent features are now available
1049 using INVITE and BAN commands. Updated the protocol specs.
1051 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1052 in the network about change in the current ban list. The notify
1053 type is not used by the client.
1055 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1056 support the invite lists.
1058 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1060 * Added new function silc_string_regexify that converts string
1061 including wildcard characters into regex string that can
1062 be used by the GNU regex library. Added into the file
1063 lib/silcutil/silcutil.[ch].
1065 Added silc_string_regex_combine to combine to regex strings
1066 into one so that they can be used as one regex string by
1067 the GNU regex library. Added into the file
1068 lib/silcutil/silcutil.[ch].
1070 Added silc_string_regex_match to match two strings. It returns
1071 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1073 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * Imported GNU regex to the soruce tree into lib/contrib.
1076 Fixed some compiler warning from the regex.c.
1078 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1080 * Fixed MOTD command in the server to work in router environment.
1082 * Fixed the MOTD command in the client library to support
1083 the server argument in the command.
1085 * Added `nickname_len' argument to the silc_idlist_add_client
1086 in the server, as the `nickname' argument may be binary data
1089 * Added silc_idlist_get_channels to return all channels from
1092 * Implemented LIST command to the server. Affected file is
1095 * Implemented the LIST command to the client library and on the
1098 * Added [<user count>] argument to the LIST command reply.
1099 With private channels the user count is not shown.
1101 * Updated TODO and README.
1103 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * The client entry's data.registered must be TRUE even with
1106 global client entry on global client list. The data.registered
1107 is used to check whether the client is anymore in the network,
1108 for example with WHOWAS command so it must be valid.
1110 * Fixed the WHOWAS command in the server. It now actually works
1111 in router environment. Added function into silcd/command_reply.c
1112 silc_server_command_reply_whowas_save.
1114 * Added silc_idlist_purge function to the silcd/idlist.c
1115 to periodically purge the ID Cache.
1117 * Fixed INFO command in the server. It works now in router
1118 environment. Added <server name> argument to the INFO command
1119 reply. Updated the protocol specs.
1121 * Fixed minor bug in silc_idcache_purge to not purge if the
1122 expire value is zero.
1124 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1125 they were buggy because of the WHOWAS information.
1127 * Fixed local command MSG to handle the async resolving of
1128 the remote client properly. It used to fail the first MSG.
1129 Affected file silc/local_command.c.
1131 * Added `data_len' field to SilcIDCache context.
1133 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1135 * Update TODO. Todo in commands in the server.
1137 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1139 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1140 used by routers as broadcast packet to inform other routers
1141 about the changed user mode.
1143 Implemented the notify handling in the server. Affected file is
1144 silcd/packet_receive.c. Added the function
1145 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1147 * Added new generic Channel Payload and deprecated the New Channel
1148 Payload. The New Channel Payload is now the generic Channel
1151 * Added new argument `mode' to the silc_server_send_new_channel
1152 as it is required in the Channel Payload now.
1154 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1155 and created a new and real SilChannelPayload to represent the
1156 new generic Channel Payload. Implemented the encode/decode
1157 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1159 * Added silc_server_get_client_channel_list to return the list
1160 of channels the client has joined for WHOIS command reply.
1161 Affected file silcd/server.[ch].
1163 * Implemented the channel list sending in the WHOIS command reply
1164 in server and in the client.
1166 Implemented the channel list displaying on the user interface
1167 as well. Affected file silc/client_ops.c.
1169 * Added silc_channel_payload_parse_list to parse list of Channel
1170 Payloads. It returns SilcDList list of SilcChannelPayloads.
1171 Client for example can use this function to parse the list of
1172 channels it receives in the WHOIS command reply. The caller
1173 must free the list by calling silc_channel_payload_list_free.
1174 Affected files lib/silccore/silcchannel.[ch].
1176 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1178 * Added one new argument <user mode> to the WHOIS command reply
1179 to return the mode of the user in SILC. Updated the protocol
1182 Implemented it to the server and client.
1184 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1186 * Fixed the mode printing on the user interface on joining.
1187 Affected file silc/client_ops.c.
1189 * Implemented the UMODE command and user modes in general to the
1190 client library and to the user interface.
1192 * Implemented the UMODE command to the server.
1194 * The server now sends UNKNOWN_COMMAND error status if client sends
1195 unknown command. Affected file silcd/command.c.
1197 * All server commands now handle the command identifier the right
1198 way when sending the command reply to the client. The client can
1199 use to identify the command replies with the identifier.
1201 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1203 * Added silc_server_get_client_route to resolve the route to
1204 the client indicated by the client ID. Affected file is
1207 * Added silc_server_relay_packet as general function to relay
1208 packet to arbitrary destination. This deprecates functions
1209 like _send_private_message_key, _relay_notify etc. Affected
1210 file is silcd/packet_send.[ch].
1212 Removed silc_server_send_key_agreement,
1213 silc_server_send_private_message_key and
1214 silc_server_packet_relay_notify functions from the file
1215 silcd/packet_send.[ch].
1219 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1220 server. Affected file silcd/packet_receive.[ch].
1222 * Implemented the KILL command to the client. Implemented the
1223 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1224 Affected files lib/silcclient/command[_reply].c and
1225 lib/silcclient/client_notify.c. Implemented the KILL notify
1226 printing in the user inteface.
1228 * Fixed a lot silc_parse_nick memory leaks from the client
1229 library in the file lib/silcclient/command.c.
1231 * Changed the silc_server_send_notify_on_channels's `sender'
1232 argument from SilcSocketConnection to SilcClientEntry to
1233 check the sender as entry and not as connection object and not
1234 to send to the client provided as argument. The affected file
1235 is silcd/packet_send.[ch].
1237 * The notify packets that are destined directly to the client used
1238 to not to be processed by the server. Now changed that and the
1239 server processes all notify packets. After relaying the packet
1240 to the client the notify packet is processed in the server.
1242 * The silc_server_free_client_data now checks whether there is
1243 pending outgoing traffic for the client and purges the data to
1244 the network before removing the client entry.
1246 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1248 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1249 an client is killed from the SILC Network. Updated the protocol
1252 Added new function silc_server_send_notify_killed to the
1253 silcd/packet_send.[ch].
1255 * Added function silc_server_packet_relay_notify to relay notify
1256 packets that are destined directly to a client. In this case
1257 the server does not process the notify packets but merely relays
1258 it to the client. Affected file silcd/packet_send.[ch].
1260 Added also silc_server_packet_process_relay_notify to check
1261 whereto relay the notify. Affected file is
1262 silcd/packet_receive.[ch].
1264 * Implemented the KILL command to the server.
1268 * Added the backup schema desgined last fall to the protocol
1269 specs for everyone to see. The specification is in the
1270 *-spec-xx.txt draft and the packet type definitions for the
1271 backup routers is in *-pp-xx.txt draft. Thusly, added also
1272 new packet type SILC_PACKET_CELL_ROUTERS.
1274 * A big security problem in the implementation discovered. The
1275 signoff of an client did not cause new channel key generation
1276 which it of course should've done. The channel keys must be
1277 always re-generated when client leaves (or signoffs) the channel.
1278 The silc_server_remove_from_channels funtion now handles
1279 the channel key re-generation.
1281 * Added `sender' argument to the silc_server_send_notify_on_channels
1282 to not to send the client provided as argument. Affected file
1283 silcd/packet_send.[ch].
1285 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1287 * Implemented OPER and SILCOPER commands into the server and
1290 * Added silc_auth_verify and silc_auth_verify_data to verify
1291 the authentication directly from the authentication payload.
1292 It supports verifying both passphrase and public key based
1293 authentication. Affected file lib/silccore/silcauth.[ch].
1295 * Added `hash' field to the SilcIDListData structure. It is the
1296 hash negotiated in the SKE protocol. Affected file is
1299 * Slight redesigning of the SilcAuthPayload handling routines.
1300 Do not send SilcPKCS but SilcPublicKey as argument.
1302 * Implemented the public key authentication support to the
1303 serverconfig. The public key is loaded from the provided path
1304 and saved as authentication data to void * pointer. Thus,
1305 changed the unsigned char *auth_data to void *auth_data;
1307 * Fixed SHUTDOWN command to send the reply before the server
1308 is shutdown. :) Affected file silcd/command.c.
1310 * Fixed fatal bug in CONNECT command. The hostname was invalid
1311 memory and server crashed. Affected file silcd/command.c.
1313 * Fixed fatal bug in CLOSE command. The server_entry became
1314 invalid but was referenced later in the command. Affected file
1317 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1319 * Fixed fatal bug in failure packet handling. Server ignored
1320 the failure and thus crashed when it came.
1324 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1326 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1327 that the command may be executed only once in (about) 2 seconds.
1328 The old SILC_CF_LAG flag is same but allows command bursts up
1329 to five before limiting.
1331 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1332 server code. Various commands now includes the CF_LAG_STRICT
1333 flag to disallow any kind of miss-use of the command.
1335 * Fixed the silc_buffer_unformat to not to allocate any data
1336 if the length of the data is zero. It used to allocate the
1337 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1339 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1341 * Changed the format of AdminConnection configuration section
1342 in the server. Added username of the admin to the format.
1343 Affected files silcd/serverconfig.[ch].
1345 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1346 to return admin configuration data by host, username and/or
1349 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1351 * Implemented WHOWAS command to the server. Added the functions:
1353 silc_server_command_whowas_parse,
1354 silc_server_command_whowas_send_reply,
1355 silc_server_command_whowas_from_client and
1356 silc_server_command_whowas_from_server
1358 * Added <Client ID> argument to the WHOWAS command reply. Updated
1359 the protocol specs accordingly.
1361 * Implemented WHOWAS command and command_reply to the client
1364 Implemented the WHOWAS printing on the user interface.
1366 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Added new argument to the WHOWAS command reply, the real name.
1369 It is an optional argument. Updated the protocol specs.
1371 * Added SilcIDCacheDestructor callback that is registered when
1372 the SilcIDCache is allocated. The callback is called when
1373 an cache entry in the ID Cache expires, or is purged from the
1374 cache. Added into lib/silccore/idcache.[ch].
1376 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1377 to destruct the client entries when the cache entry expires.
1378 Other ID Cache's in server and in the client library ignores
1381 * If the ID Cache entry's `expire' field is zero then the entry
1382 never expires. Added boolean `expire' argument to the
1383 silc_idcache_add function in the lib/silccore/idcache.[ch].
1384 If it is TRUE the default expiry value is used.
1386 * Added silc_server_free_client_data_timeout that is registered
1387 when client disconnects. By default for 5 minutes we preserve
1388 the client entry for history - for WHOWAS command.
1390 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1392 * Added support to the server to enforce that commands are not
1393 executed more than once in 2 seconds. If server receives
1394 commands from client more frequently, timeout is registered
1395 to process the commands. Affected file silcd/command.c.
1396 Added new function silc_server_command_process_timeout.
1398 * Changed NICK_NOTIFY handling in client library to check that
1399 if the client's nickname was changed, so there is no need to
1400 resolve anything from the server.
1402 * Removed error printing from the WHOIS and IDENTIFY commands.
1403 If error occurs then it is ignored silently in the client library.
1404 The application, however, may map the received error to
1405 human readable error string. The application currently maps
1406 the NO_SUCH_NICKNAME error to string.
1408 * Made the command status message public to the application. Moved
1409 them from lib/silcclient/command_reply.c to
1410 lib/silcclient/command_reply.h. The application can map the
1411 received command status to the string with the
1412 silc_client_command_status_message function.
1414 * Added check to the server to check that client's ID is same
1415 as the Source ID in the packet the client sent. They must
1418 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1420 * Added dist-bzip hook to the Makefile.am to make bzip2
1421 compressed distributions.
1423 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Server now enforces the maximum length for the nickname and
1426 the channel as protocol specification dictates. 128 bytes for
1427 nickname and 256 bytes for channel name.
1429 * Moved the WHOIS printing to the application. The client libary
1430 does not print out the WHOIS information anymore, the application
1431 must do it. Renamed silc_client_command_reply_whois_print to
1432 the silc_client_command_reply_whois_save.
1434 The client's idle time is also sent to the application now, and
1435 the idle is shown on screen.
1437 * Added silc_client_command_reply_identify_save to save the
1438 received IDENTIFY entries.
1440 * Do not check for channel private keys in message sending and
1441 reception if the channel does not have the PRIVKEY mode set.
1442 Affected file lib/silclient/client_channel.c.
1444 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1446 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1447 just surfaced after chaning the JOIN procedure.
1449 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1451 * Added silc_client_get_clients_by_list to get client entries
1452 from Client ID list, that is returned for example by JOIN
1453 and USERS command replies. The application should use this
1454 function for example when JOIN command reply is received to
1455 resolve the clients already on the channel (library does not
1456 do that anymore as USERS command reply is not used in the JOIN
1457 procedure anymore). Affected files lib/silcclient/silcapi.h and
1458 lib/silcclient/idlist.c.
1460 * JOIN command reply and USERS command reply returns now SilcBuffer
1461 pointers instead of unsigned char pointers when returning
1462 the client list and mode list.
1464 * Added <Client ID> argument to the JOIN command reply, mainly
1465 for the server to identify for which client the command was
1466 originally sent. Updated protocol specs accordingly.
1468 * Added SilcDlist private_key pointer to the SilcChannelEntry
1469 in the client to support the channel private keys. Affected
1470 file is lib/silcclient/idlist.h.
1472 * Added SilcChannelPrivateKey argument to the function
1473 silc_client_send_channel_message so that application can choose
1474 to use specific private ke if it wants to. If it is not provided,
1475 the normal channel key is used, unless private keys are set.
1476 In this case the first (key that was added first) is used
1477 as the encryption key.
1479 * Implemented the support for channel private key handling.
1480 Implemented the following functions:
1482 silc_client_add_channel_private_key,
1483 silc_client_del_channel_private_keys,
1484 silc_client_del_channel_private_key,
1485 silc_client_list_channel_private_keys and
1486 silc_client_free_channel_private_keys
1488 Affected file lib/silcclient/client_channel.c.
1490 * Added the support for the private keys in the channel message
1491 sending and encryption and in the message reception and
1492 decryption. Affected funtions are
1493 silc_client_send_channel_message and silc_client_channel_message.
1495 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1497 * Added SKE's key verify callback to the client library's
1498 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1500 * Removed the statement that server (or router) must send USERS
1501 command reply when joining to the channel so that the client
1502 knows who are on the channel. Instead, the client list and
1503 client's mode list is now sent in the JOIN command reply to the
1504 client who joined channel. This is better solution.
1506 * Added function silc_server_get_users_on_channel and function
1507 silc_server_save_users_on_channel to the silcd/server.[ch].
1509 * Removed function silc_server_command_send_users from the
1512 * Do not show topic on the client library anymore. The topic is
1513 sent in the command reply notify to the application and the
1514 application must show the topic now.
1516 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1518 * Added client searching by nickname hash into the IDENTIFY and
1519 WHOIS commands in the server as they were clearly missing from
1520 them. Affected file is silcd/command.c.
1522 * Fixed a bug in private message receiving in the client library.
1523 The remote ID was freed and it wasn't supposed, now it is
1526 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * Minor fix to the channel payload; allocate the data area, as it
1529 needs to be of specific length.
1531 * If the key agreement port is zero then the operating
1532 system will define the bound port. Affected files are
1533 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1535 * Added new function silc_channel_payload_decrypt into the file
1536 lib/silccore/silcchannel.[ch].
1538 * Moved the channel message etc, check from silc_packet_decrypt
1539 to applications. The library calls now a generic
1540 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1541 when the packet is either normal or special. This was done to
1542 allow more wide range of checking that was not allowed when
1543 the code was in library. Now applications can do virtually any
1544 checks to the packet and return to the library the decision how
1545 the packet should be processed. Affected files are
1546 lib/silccore/silcpacket.[ch].
1548 Added silc_server_packet_decrypt_check to the server and
1549 silc_client_packet_decrypt_check to the client library.
1551 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1552 to send with specified source and destination information.
1554 * Channel message delivery between routers was broken after the
1555 channel key distribution was fixed earlier. The channel key
1556 was used be to distributed to other routers as well which is not
1557 allowed by the protocol. Now this is fixed and channel keys
1558 really are cell specific and the channel message delivery between
1559 routers comply with the protocol specification.
1561 * Fixed various commands in server to check also the global list
1562 for the channel entry and not just the local list. The affected
1563 file silcd/command.c.
1565 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1567 * Added assert()s to buffer formatting and unformatting routines
1568 to assert (if --enable-debug) when error occurs. Affected
1569 file: lib/silcutil/silcbuffmt.c.
1571 * Changed to auto-reconnect to check whether the remote host is
1572 router and register the re-connect timeout if it is. It used
1573 to check that whether we are normal server, but router must do
1574 auto-reconnect with another router as well. Affected file
1577 * Removed the [<key len>] option from CMODE command as the cipher
1578 name decides the key length, nowadays. See the defined ciphers
1579 from the protocol specification.
1581 * Added [<hmac>] option to the CMODE command to define the HMAC
1582 for the channel. Added SILC_CMODE_HMAC channel mode.
1584 * Added [<hmac>] option for the JOIN command so that user can
1585 select which HMAC is used to compute the MACs of the channel
1588 * Added Hmac field to the Channel Message Payload. The integrity
1589 of plaintext channel messages are now protected by computing
1590 MAC of the message and attaching the MAC to the payload. The
1591 MAC is encrypted. Now, it is clear that this causes some
1592 overhead to the size of the packet but rationale for this is that
1593 now the receiver can verify whether the channel message decrypted
1594 correctly and also when private keys are set for the channel the
1595 receiver can decrypt the packet with several keys and check from
1596 the MAC which key decrypted the message correctly.
1598 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1599 lib/silccrypt/silccipher.[ch].
1601 * Added silc_hash_len to return the digest length into the
1602 lib/silcrypt/silchash.[ch].
1604 * Rewrote parts of Silc Channel Payload interface in the
1605 lib/silccore/silcchannel.[ch]. The encode function now also
1606 encrypts the packet and parse function decrypts it.
1608 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Fixed a minor formatting bug in the SKE's key material processing.
1611 It actually might have processed the keys wrong way resulting
1614 * Redefined the mandatory HMAC algorithms and added new algorithms.
1615 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1616 and hmac-md5 truncated to 96 bits. The mandatory is now
1617 hmac-sha1-96. Rest are optional (including the one that used
1618 to be mandatory). Rationale for this is that the truncated HMAC
1619 length is sufficient from security point of view and can actually
1620 make the attack against the HMAC harder. Also, the truncated
1621 HMAC causes less overhead to the packets. See the RFC2104 for
1624 * Added new [hmac] configuration section. The SKE used to use
1625 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1626 is of course wrong. The official names that must be proposed in
1627 the SKE are the ones defined in the protocol specification
1628 (hmac-sha1-96 for example). The user can configure any hmac
1629 using any hash function configured in the [hash] section. At
1630 least, the mandatory must be configured.
1632 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1634 * Added HMAC list to the SKE proposal list. It has now both
1635 hash algorithm list and HMAC list. This makes the protocol
1636 incompatible with previous versions. The SKE now seems to work
1637 the way it is supposed to work, for the first time actually.
1639 * Defined plain Hash algorithms to the protocol specification.
1642 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1644 * Implemented support for key agreement packets into the server.
1645 Added functions silc_server_key_agreement and
1646 silc_server_send_key_agreement. Other than these functions,
1647 server has nothing to do with this packet.
1649 * Added support for private message key packets into the server.
1650 Added functions silc_server_private_message_key and
1651 silc_server_send_private_message_key.
1655 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1656 called in the protocol's final callback instead in the END
1657 protocol state. This makes a little more sense and in the same
1658 time in client we can use the same protocol routines for normal
1659 key exchange and to key agreement packet handling as well.
1661 * Added to both client's and server's KE protocol context the
1662 SilcSKEKeyMaterial pointer to save the key material. We will
1663 bring the key material to the protocol's final callback by doing
1664 this. The final callback must free the key material.
1666 * Added SKE's packet_send callback into client's KE protocol
1667 context so that the caller can choose what packet sending function
1668 is used. This way we can use different packet sending when
1669 doing normal SKE when doing key agreement packet handling (in
1670 the key agreement packet handling we do not want to encrypt
1673 * Implemented the responder side of the key agreement routines
1674 in the client. The client can now bind to specified port and
1675 accept incoming key negotiation. The key material is passed
1676 to the application after the protocol is over.
1678 * Implemented the processing of incoming Key Agreement packet
1679 in the client. Added function silc_client_key_agreement to
1682 * Implemented the intiator side of the key agreement routines
1683 in the client. The client can now initiate key agreement with
1684 another remote client. The key material is passed to the
1685 application after the protocol is over.
1687 * Created client_keyagr.c to include all the key agreement
1690 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1691 SILC_TASK_CALLBACK except that it is not static.
1693 * Created client_notify.c and moved the Notify packet handling
1694 from the client.[ch] into that file.
1696 * Created client_prvmsg.c and moved all private message and
1697 private message key routines from the client.[ch] into that file.
1699 * Create client_channel.c and moved all channel message and
1700 channel private key routines from the client.[ch] into that file.
1702 * Changed silc_client_get_client_by_id_resolve to resolve with
1703 WHOIS command instead of IDENTIFY command, in the file
1704 lib/silclient/idlist.c.
1706 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1708 * Implemented the SKE's responder side to the Client library.
1710 * When FAILURE is received to the protocol do not trust it
1711 blindly. Register a timeout to wait whether the remote closes
1712 the connection as it should do it, only after that process the
1713 actual failure. This was changed to both client and server.
1715 * Added client_internal.h to include some of the structures
1716 there instead of client.h in lib/silcclient/.
1718 * Added function silc_task_unregister_by_callback to unregister
1719 timeouts by the callback function.
1721 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1723 * Some "Incomplete WHOIS info" errors has been appearing on the
1724 log files. Took away the entry->userinfo check from WHOIS
1725 reply sending. The entry->userinfo is now " " if client did not
1726 provide one. I thought this was fixed earlier but something
1727 is wrong still. Let's see if the error still appears.
1729 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1731 * Fixed a minor bug in the login when the channel key is
1732 re-generated in the server. It used to generate the key in
1733 wrong order and thus caused problems in the channel traffic.
1735 * Fixed a minor bug in channel key distsribution after
1736 KICK command. The key was not sent to the router even though
1739 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1741 * Added silc_ske_process_key_material_data as generic routine
1742 to process any key material as the SILC protocol dictates. The
1743 function is used by the actual SKE library but can be used by
1744 applications as well. This relates to the private message keys
1745 and the channel private keys since they must be processed the
1746 same way the normal SILC session keys. The protocol dictates
1747 this. Affected files: lib/silcske/silcske.[ch].
1749 Added also silc_ske_free_key_material to free the
1750 SilcSKEKeyMaterial structure.
1752 * Defined silc_cipher_set_key function to set the key for
1753 cipher without using the object's method function. The affected
1754 files: lib/silccrypt/silccipher.[ch].
1756 * Implemented silc silc_client_add_private_message_key,
1757 silc_client_add_private_message_key_ske,
1758 silc_client_del_private_message_key,
1759 silc_client_list_private_message_keys and
1760 silc_client_free_private_message_keys functions in the
1763 Added functions silc_client_send_private_message_key to send
1764 the Private Message Key payload and silc_client_private_message_key
1765 to handle incoming Private Message Key payload.
1767 * Added Cipher field to the Private Message Key payload to set
1768 the cipher to be used. If ignored, the default cipher defined
1769 in the SILC protocol (aes-256-cbc) is used.
1771 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1773 * Removed lib/silcclient/ops.h file.
1775 Redefined parts of the SILC Client Library API. Created new
1776 file silcapi.h that deprecates the ops.h file and defines the
1777 published Client Library API. Defined also private message key
1778 API and channel private key API into the file.
1780 This is the file that the application must include from the
1781 SILC Client Library. Other files need not be included by
1782 the application anymore.
1784 * Added new key_agreement client operation callback and also
1785 defined the Key Agreement library API for the application.
1787 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1789 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1790 is used by clients to request key negotiation between another
1791 client in the SILC network. If the negotiation is started it
1792 is performed using the SKE protocol. The result of the
1793 negotiation, the secret key material, can be used for example
1794 as private message key.
1796 Implemented the Key Agreement payload into the files
1797 lib/silccore/silauth.[ch].
1799 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1801 * Redefined ciphers for the SILC protocol. Added some new ciphers
1802 and defined the key lengths for the algorithms. Changed the
1803 code accordingly. The default key length is now 256 bits.
1805 * Fixed SKE key distribution function silc_ske_process_key_material
1806 when the key length is more than 128 bits. The default key
1807 length in SILC is now 256 bits.
1809 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1810 to indicate unsupported algorithm.
1812 * Renamed rijndael.c to aes.c and all functions as well.
1814 * Fixed a long standing channel key setting bug in client library.
1815 Weird that it has never surfaced before.
1817 * Fixed bug in channel deletion. If the entire channel is removed
1818 then it must also delete the references of the channel entry
1819 from the client's channel list as the client's channel entry and
1820 the channel's client entry share same memory.
1822 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Implemented CONNECT and SHUTDOWN commands in the client.
1826 * Implemented CLOSE command to the client.
1828 * Added the function silc_idlist_find_server_by_name into the
1829 files silcd/idlist.[ch].
1831 Added the function silc_idlist_find_server_by_conn into the
1832 files silcd/idlist.[ch].
1834 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1836 * DIE command was renamed to SHUTDOWN. Updated the both code
1839 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1840 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1842 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1845 * Added function silc_server_create_connection function to create
1846 connection to remote router. My server implementation actually
1847 does not allow router to connect to normal server (it expects
1848 that normal server always initiates the connection to the router)
1849 so the CONNECT command is only good for connecting to another
1852 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1854 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1855 or some other client was kicked from the channel.
1857 Implemented the handling of the notify type to both client
1860 Implemented silc_server_send_notify_kicked to send the KICKED
1861 notify. It is used to send it to the server's primary router.
1863 * Implemented the KICK command into server and client.
1865 * Added `query' argument to the silc_idlist_get_client function
1866 to indicate whether to query the client from server or not if
1869 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1870 to indicate that the client is not channel founder.
1874 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1876 * Removed the rng context from SilcPacketContext structure and
1877 changed that the packet routine uses the Global RNG API.
1879 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1881 * Added support for quit message that client can "leave" on the
1882 channel when it quits the SILC. It is ditributed inside the
1883 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1885 Added silc_server_free_client_data that will take the
1886 signoff message as argument.
1888 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1890 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1892 * Updated parts of the protocol specification to keep it up
1895 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1898 payloads in one packet.
1900 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1901 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1902 use now the new List flag.
1904 * Also deprecated the following packet types: REPLACE_ID,
1905 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1907 * Added list support for Notify packet in server.
1909 * Added silc_server_send_notify_channel_change to send the
1910 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1911 the silc_server_send_replace_id.
1913 * Added silc_server_send_notify_nick_change to send the
1914 NICK_CHANGE notify type. Deprecates the function
1915 silc_server_send_replace_id.
1917 * Added silc_server_send_notify_join to send the JOIN notify type.
1918 Deprecates the function silc_server_send_new_channel_user.
1920 * Added silc_server_send_notify_leave to send LEAVE notify type.
1921 Deprecates the function silc_server_send_remove_channel_user.
1923 * Added silc_server_send_notify_cmode and
1924 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1925 types. Deprecates the silc_server_send_set_mode function.
1927 * Added SERVER_SIGNOFF notify type to indicate that server has
1928 quit. This means that all clients on the channel from that
1929 server will drop. This can be also used when netsplit happens.
1931 Deprecated REMOVE_ID packet type since it is not needed anymore
1934 Added silc_server_send_notify_server_signoff to send the
1935 SERVER_SIGNOFF notify type. Deprecates the function
1936 silc_server_send_remove_id.
1938 Added also silc_server_send_notify_signoff to send the
1939 SIGNOFF notify type.
1941 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1942 SILC protocol from this day on. Changed the protocol
1943 specification as well.
1945 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1946 notify type. It is used between routers to notify about
1947 topic changes on a channel.
1949 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1952 * Partly updated the protocol specification to comply with the
1953 changes now made. It is still though a bit outdated.
1955 * The JOIN notify type now takes one extra argument <Channel ID>.
1956 The packet used to be destined to the channel but now the
1957 JOIN type may be sent as list thus it is impossible to
1958 destine it to any specific channel. By adding this argument
1959 it is again possible.
1961 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Added CREDITS file. The CHANGES and CREDITS file will appear
1964 in the distribution as well.
1966 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1968 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1969 types in the server's silcd/packet_receive.c.
1971 * Implemented CMODE and CUMODE to work in router environment.
1973 * Fixed minor encoding and decoding buglet from the
1974 lib/silccore/silcmode.c.
1976 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1979 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1981 * Changed all SilcConfigServer* and silc_config_server* to
1982 SilcServerConfig* and silc_server_config*, respectively.
1985 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1987 * Associated the ID (client or server ID) to the Authentication
1988 Payload to avoid any possibility of forging. Updated the
1989 protocol specification and the code accordingly.
1991 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1993 * The RSA key length is now save to the RsaKey context in the
1994 key generation process in lib/silccrypt/rsa.c. The key length
1995 is now used to figure out the maximum size of the block allowed
1996 to be encrypted/signed.
1998 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1999 is equivalent to the silc_mp_mp2bin but does not allocate any
2002 * Changed silc_mp_mp2bin API to take length argument. If it is
2003 non-zero then the buffer is allocated that large. If zero, then
2004 the size is approximated using silc_mp_sizeinbase, which however
2007 * Created Global RNG API which is global RNG that application can
2008 initialize. After initializing, any routine anywhere in the
2009 code (including library) can use RNG without allocating a new
2010 RNG object. This was done to allow this sort of use of the
2011 RNG in code that has no chance to allocate RNG object. All
2012 applications currently allocate this and many routines in the
2013 library use this. Affected file lib/silccrypt/silcrng.[ch].
2015 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2016 it to use the Global RNG API.
2018 * Defined Authentication Payload into protocol specification that
2019 is used during SILC session to authenticate entities. It is
2020 used for example by client to authenticate itself to the server
2021 to obtain server operator privileges.
2023 Implemented this payload into the lib/silccore/silcauth.[ch].
2024 Implemented also routines for public key based authentication
2025 as the new protocol specification dictates.
2027 Moved definitions of different authentication methods from
2028 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2030 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2031 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2032 silc_pkcs_verify_with_hash functions into the file
2033 lib/silccrypt/silcpkcs.[ch].
2035 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2037 * The client entry's userinfo pointer must be always valid.
2038 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2039 will fail since it requires the userinfo. Now, the userinfo
2040 is allocated as "" if actual userinfo does not exist. Actually,
2041 it must exist and it is totally Ok to drop client connections
2042 that does not announce the userinfo. However, we will make
2043 this workaround for now.
2045 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2046 to return the remote port by socket.
2048 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2051 SILC_SERVER_PENDING_EXEC and added an new macro
2052 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2053 data or when error occurs while processing the pending command.
2055 Added new argument `destructor' into silc_server_command_pending
2056 and to the SilcServerCommandPending object. This destructor is
2057 now called after calling the pending callback or if error occurs
2058 immediately. If error occurs the actual pending callback won't
2059 be called at all - only the destructor. The destructor may be
2060 NULL if destructor is not needed.
2062 All this applies for client library code as well. Similar
2063 changes were made there as well for the pending commands.
2065 In the client, the application must now allocate the
2066 SilcClientCommandContext with the silc_client_command_alloc
2069 * Added reference counter to the SilcServerCommandContext. Added
2070 function silc_server_command_alloc and silc_server_command_dup
2073 Same type of functions added to the client library for the same
2076 * Removed the cmd_ident from IDListData away since it is now
2077 global for all connections. It is the command identifier used
2078 in command sending and with pending commands. The affected file
2081 * Added reference counter to the SilcSocketConnection objecet to
2082 indicate the usage count of the object. The object won't be
2083 freed untill the reference counter hits zero. Currently only
2084 server uses this, and client ignores it. The client must be
2085 set to use this too later. The affected files are
2086 lib/silccore/silcsockconn.[ch]. Added also the function
2087 silc_socket_dup to increase the reference counter.
2089 This was mainly added because it is possible that the socket
2090 is removed underneath of pending command or other async
2091 operation. Now it won't be free'd and proper DISCONNECTING
2092 flags, etc. can be set to avoid sending data to connection that
2093 is not valid anymore.
2095 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2096 the connection. After that it sets SILC_SET_DISCONNECTED.
2097 It is, however, possible that the socket data is not still freed.
2098 The silc_server_packet_process now checks that data is not
2099 read or written to connection that is DISCONNECTED. The socket
2100 get's freed when the reference counter hits zero.
2102 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2104 * Changed the client operation API: channel_message operation's
2105 `sender' is now the client entry of the sender, not the nickname
2106 and the `channel' is the channel entry, not the channel name.
2108 In the private_message operation the `sender' is now also the
2109 client entry of the sender not the nickname.
2111 Affected file is lib/silcclient/ops.h and all applications
2112 using the client operations.
2114 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2116 * Moved the calling of ops->connect() from connect_to_server_final
2117 into receive_new_id functin since that is the point when the
2118 client is actually allowed to send traffic to network. The
2119 affected file is lib/silcclient/client.c.
2121 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2123 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2124 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2125 (if needs broadcasting) instead of broadcasting the packets one
2126 by one which would make a burst in the network traffic.
2128 * Added `broadcast' argument to the functions in silcd/server.[ch]
2129 silc_server_create_new_channel[_with_id] to indicate whether
2130 to send New Channel packet to primary router.
2132 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2134 * Added new function into the silcd/server.[ch] files:
2135 silc_server_create_new_channel_with_id to create new channel with
2136 already existing Channel ID.
2138 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2139 lib/silccore/silcpacket.h. This packet is used t send list of
2140 Set Mode payloads inside one packet. Server uses this to set
2141 the modes for the channels and clients on those channels, that it
2142 announced to the router when it connected to it. The protocol
2143 specification has been updated accordingly.
2145 * The silc_server_new_channel did not handle the packet coming
2146 from normal server as it normally does not send that. However,
2147 when it announces its channels it does send it. Implemented
2148 the support for that.
2150 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2151 into the file lib/silccore/id.h.
2153 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2155 * Fixed memory leaks in the functions silc_idlist_del_client,
2156 silc_idlist_del_channel and silc_idlist_del_server in the file
2157 silcd/idlist.c. All of those leaked like a sieve.
2159 * Fixed some small memory leaks in the client's function
2160 silc_client_notify_by_server.
2162 * Added functions into silcd/server.c: silc_server_announce_clients,
2163 silc_server_announce_channels and silc_server_announce_server.
2164 These functions are used by normal and router server to announce
2165 to its primary router about clients, channels and servers (when
2166 router) that we own. This is done after we've connected to the
2169 These functions effectively implements the following packet types:
2170 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2171 and SILC_PACKET_NEW_ID_LIST.
2173 * Added new functions into the silcd/packet_receive.[ch]:
2174 silc_server_new_id_list, silc_server_new_channel_list and
2175 silc_server_new_channel_user_list to handle the incoming
2176 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2178 * Added support of changing Channel ID in the function
2179 silc_server_replace_id. If the server that announces a channel
2180 to the router already exists in the router (with same name but
2181 with different Channel ID), router is responsible to send
2182 Replace ID packet to the server and force the server to change
2183 the Channel ID to the one router has.
2185 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2186 client that the Channel ID has been changed by the router. The
2187 normal server sends this to the client. Client must start using
2188 the new Channel ID as the channel's ID.
2190 Implemented handling of this new type into lib/silcclient/client.c
2191 into the function silc_client_notify_by_server.
2193 * Added new function silc_idlist_replace_channel_id into the files
2194 silcd/idlist.[ch] to replace the Channel ID.
2196 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2198 * Call silc_server_command_identify_check always when processing
2199 the IDENTIFY command in silcd/command.c
2201 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2203 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2204 send keepalive packets. The packet can be sent by clients,
2205 servers and routers.
2207 Added function silc_socket_set_heartbeat into the file
2208 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2209 If not set, the heartbeat is not performed. The actual
2210 heartbeat is implemented in the low level socket connection
2211 library. However, application is responsible of actually
2214 Added silc_server_send_heartbeat to send the actual heartbeat
2215 packet into silcd/packet_send.[ch]. Server now performs
2216 keepalive with all connections.
2218 * Added silc_task_get_first function into lib/silcutil/silctask.c
2219 to return the timeout task with shortest timeout. There was a bug
2220 in task unregistration that caused problems. TODO has been
2221 updated to include that task system must be rewritten.
2223 * The client library will now resolve the client information when
2224 receiving JOIN notify from server for client that we know but
2225 have incomplete information.
2227 * Rewrote parts of silc_server_remove_from_channels and
2228 silc_server_remove_from_one_channel as they did not remove the
2229 channel in some circumstances even though they should've.
2231 * Encryption problem encountered in server:
2233 The LEAVE command used to send the Channel Key packet to the
2234 router immediately after generating it. However, the code
2235 had earlier sent Remove Channel user packet but not immediately,
2236 ie. it was put to queue. The order of packets in the router
2237 was that Channel Key packet was first and Remove Channel User
2238 packet was second, even though they were encrypted in the
2239 reverse order. For this reason, MAC check failed. Now, this
2240 is fixed by not sending the Channel Key packet immediately but
2241 putting it to queue. However, this is more fundamental problem:
2242 packets that are in queue should actually not be encrypted
2243 because packets that are sent immediately gets encrypted
2244 actually with wrong IV (and thus MAC check fails). So, packets
2245 that are in queue should be encrypted when they are sent to
2246 the wire and not when they put to the queue.
2248 However, the problem is that the current system has not been
2249 designed to work that way. Instead, the packet is encrypted
2250 as soon as possible and left to the queue. The queue is then
2251 just purged into wire. There won't be any fixes for this
2252 any time soon. So, the current semantic for packet sending
2255 o If you send packet to remote host and do not force the send
2256 (the packet will be in queue) then all subsequent packets to the
2257 same remote host must also be put to the queue. Only after the
2258 queue has been purged is it safe again to force the packet
2261 o If you send all packets immediately then it safe to send
2262 any of subsequent packets through the queue, however, after
2263 the first packet is put to queue then any subsequent packets
2264 must also be put to the queue.
2266 Follow these rules and everything works fine.
2268 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2270 * Added new function silc_server_remove_clients_by_server to
2271 remove all client entries from ID list when the server connection
2272 is lost. In this case it is also important to invalidate all
2273 client entires as they hold the invalid server entry. This
2274 fixes fatal bug when server has lost connection and will reconnect
2277 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2279 * Made some sanity checks to silc_server_daemonise like to check
2280 whether the requested user and group actually exists.
2282 * Added sanity check to SKE's silc_ske_responder_finish to check
2283 that the public and private key actually is valid.
2285 * Invalidate the client's nickname when receiving Replace ID
2286 packet and the Client ID is being replaced. This means that the
2287 server will query the nickname if someone needs it (client)
2290 * Sort the ID Cache in client library when the ID Cache data
2291 has changed (needs sorting).
2293 * Do not allow for SILC client to create several connections to
2294 several servers. The client does not support windows right now
2295 and generating multiple connections causes weird behaviour.
2297 Irssi-silc client does support windows and can handle several
2298 connections without problems, see: www.irssi.org and SILC plugin.
2300 * Fixed some places where client was added to the IDList. The
2301 rule of thumb is following (in order to get everything right):
2302 If the client is directly connected local client then the
2303 `connection' argument must be set and `router' argument must be
2304 NULL to silc_idlist_add_client function. If the client is not
2305 directly connected client then the `router' argument must
2306 bet set and the `connection' argument must be NULL to the
2307 silc_idlist_add_client function.
2309 * The funtion silc_server_packet_send_local_channel actually did
2310 not check whether the client was locally connected or not. It
2311 does that now. Fixed a bug related to LEAVE command.
2313 * Fixed Remove Channel User payload parsing bug in server's
2314 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2316 * The server's silc_server_save_channel_key now checks also the
2317 global ID list for the channel as it might not be in the local
2318 list. Fixed a bug related to LEAVE command.
2320 * Is this the end of the [<unknown>] buglet that has been lurking
2321 around for a long time? A little for loop fix in server's
2322 silc_server_command_whois_parse that is used by both IDENTIFY
2323 and WHOIS command. At least, this was a clear bug and a cause
2324 of one type of [<unknown>] buglet.
2326 * WHOIS and IDENTIFY commands call the function
2327 silc_server_command_[whois/identify]_check function even if
2328 we are not router server.
2330 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Added --with-gmp configuration option. If set the GMP
2333 is always compiled in the SILC source tree. If not set then
2334 it is checked whether the system has the GMP3 installed. If
2335 it has then the GMP won't be compiled (the system's headers
2336 and library is used), if it doesn't have it then the GMP is
2337 compiled in the SILC source tree.
2339 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Changed RSA private exponent generation to what PKCS #1
2342 suggests. We try to find the smallest possible d by doing
2343 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2344 not security fix but optimization.
2346 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2348 * Added new config entry [Identity] to fork the server and run
2349 it as specific user and group. A patch from Bostik.
2351 * Imported Dotconf configuration library into lib/dotconf.
2352 This will be used to create the SILC configuration files later.
2353 It will appear in the distsribution after this commit.
2355 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2357 * A big code auditing weekend happening. Auditing code for
2358 obvious mistakes, bugs and errors. Also, removing any code
2361 Removed files for being obsolete:
2363 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2364 inline in the file lib/silcutil/silcbuffer.h)
2366 o lib/silcutil/silcbufutil.c (the header has inline versions)
2368 Changed code to fix possible error conditions:
2370 o The buffer formatting routines now check that the destination
2371 buffer really has enough space to add the data. This applies for
2372 both buffer formatting and unformatting
2373 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2374 unformatting was changed to accomodate following rules:
2375 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2376 sent to the function while XXX_*STRING will not allocate or copy
2377 the data into the buffer. Instead it sets the pointer from the
2378 buffer into the pointer sent as argument (XXX_*STRING used to
2379 require that the pointer must be allocated already). This change
2380 makes this whole thing a bit more consistent and more optimized
2381 (note that the data returned in the unformatting with XXX_*STRING
2382 must not be freed now). The routines return now -1 on error.
2384 o Tried to find all code that use buffer_format and buffer_unformat
2385 and added return value checking to prevent formatting and
2386 especially unformatting errors and possible subsequent fatal
2389 o Changed ske->x and ske->KEY to mallocated pointers in
2390 lib/silcske/silcske.h. Fixed possible data and memory leak.
2392 o Added return value checking to all *_parse* functions. Fixed
2393 many memory leaks as well.
2395 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2396 so that buffer overflows would not happen. All code now also
2397 checks the return value as it can fail.
2399 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2401 * Added reconnection support to server if the normal server looses
2402 its connection to the router (for example if router is rebooted).
2403 The server performs normal reconnection strategy implemented
2404 to the server. Affected file silcd/server.c.
2406 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2408 * Added new packet type SILC_PACKET_SET_MODE that is used to
2409 distribute the information about changed modes (for clients,
2410 channels and clients channel modes) to all routers in the
2411 network. Updated the protocol specification accordingly.
2413 Added functions into silcd/packet_send.c and
2414 silcd/packet_receive.c: silc_server_send_set_mode,
2415 silc_server_set_mode.
2417 Added new files silcmode.[ch] into lib/silccore that implements
2418 the encoding and decoding of Set Mode Payload. Added new type
2419 SilcSetModePayload. Moved the definitions of different modes
2420 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2422 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2424 * Oops, a little mistake in server's connection authentication
2425 protocol. The protocol is not ended with FAILURE but with
2426 SUCCESS if the authentication is Ok. :) Affected file is
2429 * Implemented NICK_CHANGE notify handling in server in the file
2430 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2431 the local clients on the channel. After the changing nickname
2432 in router environment snhould work and the [<unknown>] nickname
2433 should appear no more.
2435 The silc_server_replace_id function that receives the Replace ID
2436 payload now sends the NICK_CHANGE notify type also in the file
2437 silcd/packet_receive.c
2439 * Changed WHOIS and IDENTIFY command to support the maximum amount
2440 of arguments defined in protocol specs (3328 arguments). This
2441 fixed a bug that caused problems when there were more than three
2444 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Added extra parameter, command identifier, to the
2447 silc_client_send_command so that explicit command identifier
2450 Changed that ID list routines uses specific command identifier
2451 when sending WHOIS/IDENTIFY requests to the server so that they
2452 can be identified when the reply comes back.
2454 Affected files lib/silcclient/command.[ch],
2455 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2457 * Added `sender' argument to silc_server_packet_send_to_channel
2458 to indicaet the sender who originally sent the packet to us
2459 that we are now re-sending. Ignored if NULL. Affected file
2460 silcd/packet_send.[ch].
2462 * Added some server statistics support in silcd/server_internal.h
2463 SilcServerStatistics structure and around the server code. Also
2464 send some nice statistics information when client is connecting
2467 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * Fixed channel ID decoding in server's JOIN command reply in
2470 silcd/command_reply.c
2472 * Fixed braodcasting of replace ID payload to not to send it if
2473 we are standalone server in silcd/packet_receive.c.
2475 * Fixed all channel message sending routines to not to send
2476 packets to clients that has router set, since they are routed
2477 separately in the same function earlier. Affects file
2478 silcd/packet_send.c and all channel packet sending functions.
2480 * In USERS reply, res_argv[i] are not allocated, the table
2481 is allocated. Thus changed that free the table, not its
2484 * In server's whois_check and identify_check if the client is
2485 locally connected do not send any WHOIS commands - they are not
2488 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Fixed some minor bugs in client when sending WHOIS command. The
2491 arguments was in wrong order.
2493 * Removed statis function add_to_channel from server in
2494 silcd/command.c that was previously used with the joining but
2497 * Tested USERS command in router environment successfully with two
2498 routers, two servers and two clients.
2500 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2502 * Reorganized the USERS command and command reply in client library
2503 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2504 When the command is given by user we register a pending command
2505 callback that will reprocess the command after the reply has been
2506 received from the server. When reprocessing the packet we then
2507 display the information. Thus, the USERS information is displayed
2508 now in the command callback instead of in the command reply
2509 callback. The processing of the command is same as previously
2510 when server has sent the command reply in the JOINing process.
2512 * Added to USERS command in silcd/command_reply.c to join the client,
2513 we didn't use to know about, to the channel after we've created
2514 a client entry for it. Also, for clienet we did know already still
2515 check whether it is on the channel or not and add it if not.
2517 * Removed silc_server_command_join_notify as the function and its
2520 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2522 * Changed the client's pending command handling to the same as the
2523 server's pending command handling. It is also now possible to
2524 execute command reply functions from other command reply
2525 function as the function callbacks for commands and command
2526 replies are one and same. The pending commands are not static
2527 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2528 in client connection context. Thus, pending commands are server
2529 connection specific as it is convenient.
2531 Changed the function silc_client_command_pending and
2532 silc_client_command_pending_del and added new function
2533 silc_client_command_pending_check. Removed the
2534 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2537 * Added cmd_ident, current command identifier, to the client
2538 connection context in lib/silcclient/client.h to keep track on
2539 command identifiers used in command sending. Client's command reply
2540 function handling now supports the mandatory command identifiers.
2542 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2543 funtions in client to fully support pending command callbacks.
2545 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2546 as one of the arguments to the application in the command reply
2549 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2550 before first releasing SILC but came back. Now it is removed again
2551 and should come back nomore. The FORWARDED flag was used only
2552 by the JOINing procedure by forwarding the command packet to router.
2553 Now, the JOINing procedure has been changed to more generic (due
2554 to various router environment issues) and FORWARDED is not needed
2555 anymore for anything. The protocol specification is yet to be
2558 Now, removed silc_server_packet_forward from server and the flag
2559 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2561 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2563 * Renamed NAMES command to USERS command. The NAMES was named that
2564 due to historical reasons. Now it is renamed. Also, rewrote
2565 parts of the USERS command. The nickname list is not sent anymore
2566 by the server. Only Client ID and mode lists are sent in the USERS
2567 command. Changed this also to the protocol specification.
2569 The client now resolves the names and stuff after it receives
2570 the USERS list from the server when joining to the channel.
2572 * WHOIS and IDENTIFY commands has been changed to support multiple
2573 Client ID's per command. One can now search for multiple users
2574 in the network by sending only one WHOIS or IDENTIFY command.
2575 Changed the code and the protocol specifications.
2577 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2578 uses silc_server_command_whois_parse to parse the request. */
2580 * If normal server, do not parse the WHOIS and IDENTIFY requests
2581 before sending it to the router. Saves some time.
2583 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2585 * Fixed JOIN command on client library. Wrong number of arguments
2586 used to crash the client.
2588 * Added silc_server_channel_has_global function to check whether
2589 channel has global users or not.
2591 * Added silc_server_channel_has_local function to check whether channel
2592 has locally connected clients on the channel.
2594 * The silc_server_remove_from_one_channel now checks whether the
2595 channel has global users or not after given client was removed from
2596 the channel. It also checks whether the channel has local clients
2597 on the channel anymore. If it does not have then the channel entry
2598 is removed as it is not needed anymore.
2600 * The silc_server_notify now checks on JOIN notify whether the joining
2601 client is one of locally connected or global. If it is global then
2602 the channel has now global users on the channel and that is marked
2603 to the channel entry. Also, it now saves the global client to
2604 global list who is joining and JOINs it to the channel. This is
2605 for normal server, that is.
2607 Changed silc_server_send_notify_on_channel,
2608 silc_server_packet_relay_to_channel and
2609 silc_server_packet_send_to_channel check if we are normal server
2610 and client has router set (ie. global client) do not send the
2611 message to that client, as it is already routed to our router.
2613 * Implemented LEAVE notify type handling in silc_server_notify
2616 * Tested LEAVE command in router environment successfully. Tested
2617 with two routers, two servers and two clients.
2621 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2623 * Implemented SIGNOFF notify type handling in silc_server_notify
2626 * silc_server_remove_id now removes the client entry from all channels
2627 it has joined and thusly sends SIGNOFF notify type.
2629 * Rewrote the NAMES list generation in server by removing two excess
2630 loops. The lists are created now inside one loop.
2632 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * silc_server_remove_channel_user checks now also global list
2635 for channel and client.
2637 * silc_server_new_channel_user checks now both local and global
2638 list for channel and client. Fixed a bug in client id decoding.
2639 Used to decode wrong buffer.
2641 * silc_server_channel_message checks now both local and global
2642 list for channel entry.
2644 * Tested channel joining (hence JOIN) in router environment
2645 successfully. Tested with two routers, two servers and two
2648 * Tested channel message sending in router environment successfully.
2650 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Added silc_server_save_channel_key into server.[ch] to save the
2653 received channel key in Channel Key payload processing. It is
2654 also used in JOIN command reply handling.
2656 Equivalent function silc_client_save_channel_key added into
2657 client.[ch] into client library.
2659 * Changed JOIN command reply to send information whether the channel
2660 was created or not (is existing already) and the channel key
2661 payload. Changed protocol specs accordingly.
2663 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2664 the request was sent by ID and not by nickname. Crashed on
2667 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2670 now correctly save the received data.
2672 * silc_server_free_sock_user_data now notifies routers in the
2673 network about entities leaving the network.
2675 At the same time implemented functions silc_server_remove_id
2676 and silc_server_send_remove_id to receive and send REMOVE_ID
2677 packets. The packet is used to notify routers in the network
2678 about leaving entities. The ID removed will become invalid in
2681 * Added function silc_idlist_del_server into server. Removes and
2682 free's server entry from ID list.
2684 * silc_server_private_message function now checks, if we are router,
2685 that the destination ID really is valid ID, naturally.
2687 * In router when NEW_ID packet is received (for new client) the
2688 hash of the Client ID is saved in the ID Cache but the
2689 client->nickname is set to NULL, instead of putting the hash
2692 IDENTIFY command now also checks that client->nickname must be
2693 valid. If it is not if will request the data from the server who
2694 owns the client. Added new function
2695 silc_server_command_identify_check.
2697 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2698 to set the command to already allocated Command Payload.
2700 * Tested private message sending in router environment with two
2701 routers, two servers and two clients. Fixed minor bugs and now
2704 * Fixed segfault from client's NAMES command. Used to crash if
2707 * Forwarded packets must not be routed even if it is not destined
2708 to the receiver. Changed server code comply with this.
2710 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2712 * Added `require_reverse_mapping' boolean value to ServerParams
2713 structure. If TRUE (not default) the server will require that
2714 the connecting host has fully qualified domain name.
2716 If the reverse mapping is not required and hostname could not be
2717 found the IP address is used as hostname.
2719 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Implemented version string checking to both client and server.
2722 The check is incomplete currently due to the abnormal version
2723 strings used in development version of SILC.
2725 * Changed all command functions in server to use the new
2728 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2730 * Changed char *data to unsigned char *data in ID Cache system to
2731 support binary data as ID Cache data. Changed code to support
2732 binary data in lib/silccore/idcache.c.
2734 * Renamed silc_server_packet_relay_command_reply to
2735 silc_server_command_reply as it is normal packet receiving
2736 function. Rewrote the function to accept command replys for
2737 servers and not only for clients.
2739 * Mark remote router always as registered server if we are connecting
2740 to it. Otherwise, commands sent by the router to us are ignored.
2742 * All ID List find routines now returns the ID Cache Entry pointer
2743 as well if requested.
2745 * WHOIS command works now in router environment, tested with two
2746 routers, two servers and two clients.
2748 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2749 in router environment (as it is almost equivalent to WHOIS) but
2750 hasn't been tested thoroughly. Added new functions:
2752 silc_server_command_identify_parse
2753 silc_server_command_identify_send_reply
2754 silc_server_command_identify_from_client
2755 silc_server_command_identify_from_server
2757 * Disabled route cache adding because adding two different ID's with
2758 same IP replaces the old cache entry thus giving wrong route.
2759 The entry->router->connection is always the fastest route anyway
2760 so route cache may not be needed. Of course, new routes maybe
2761 established after receiving the ID when the entry->router->connection
2762 might not be anymore the most optimal.
2764 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Add route cache for received ID for fast routing.
2768 * Added silc_server_packet_route to route received packet on router
2769 that is not destined to us.
2771 * Renamed silc_server_get_route to silc_server_route_get.
2773 * Added id_string and id_string_len fields into SilcServer to
2774 include encoded ServerID for fast comparing without excess
2775 encoding of the ID's.
2777 * Cleaned up WHOIS command on server side. Added following static
2780 silc_server_command_whois_parse
2781 silc_server_command_whois_check
2782 silc_server_command_whois_send_reply
2783 silc_server_command_whois_from_client
2784 silc_server_command_whois_from_server
2786 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2787 arguments in command replies. All command functions should be
2788 updated to use this macro.
2790 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2792 * Minor typo fixes on command reply handling on server.
2794 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2796 * Added silc_server_command_add_to_channel internal routine to add
2797 the client to the channel after router has created the channel and
2798 sent command reply to the server.
2800 * Added generic silc_server_send_command to send any command from
2803 * Use static buffer with ID rendering instead of duplicating data.
2805 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2807 * Fixed a channel user mode bug when joining to a channel server gave
2808 everybody channel founder rights, oops.
2810 * We mark ourselves as the router of the incoming server connection
2811 if we are router ourselves. This way we can check in some packet
2812 sending functions whether it is locally connected server. For
2813 incoming router connections we put NULL.
2815 * For router sending packets locally means now always sending the
2816 packet cell wide; to local clients and local servers. For normal
2817 server sending packet locally means sending it to only local
2820 * Fixed the JOIN command to really work in router environment. If the
2821 channel is created it is always created by the router. Router is
2822 also responsible of making the initial joining to the channel,
2823 sending JOIN notify to the sending server and distributing
2824 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2825 does not exist server doesn't do anything else but forward the
2826 command to the router which performs everything.
2828 * Added silc_server_send_channel_key function to send the Channel Key
2831 * Added silc_server_create_channel_key to create new channel key. The
2832 channel key is now re-generated everytime someone joins or leaves
2833 a channel, as protocol dictates. Note: channel->key_len is the
2836 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2838 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2839 packet_receive.[ch] to separate packet sending and receiving
2840 routines. The server.[ch] now includes everything else including
2841 actual packet processing (writing and reading data) and other
2844 Renamed silc_server_private_message_send_internal to
2845 silc_server_send_private_message. The routine is still though
2846 used only to relay private messages as server does not send
2847 private messages itself.
2849 Renamed silc_server_new_channel to silc_server_create_new_channel
2850 and added new function sicl_server_new_channel that handles the
2851 incoming New Channel packet. Added also new sending function
2852 silc_server_send_new_channel to send New Channel Payload.
2854 * Added new function silc_server_notify to process incoming notify
2855 packet to the server/router. Server may then relay the notify
2856 to clients if needed.
2858 * Added new function silc_server_new_channel_user to process incoming
2859 New Channel User packet. Router will redistribute the packet and
2860 send JOIN notify to its local clients and locally connected servers
2861 if needed. Normal server will send JOIN notify to its local client
2862 on same channel when received this packet. Added also corresponding
2863 sending function silc_server_send_new_channel_user to sent the
2866 * Added boolean route argument to send_notif_to_channel and
2867 packet_send_to_channel functions to attempt to route the packet
2868 if it is TRUE and send only locally if it is FALSE.
2870 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * silc_server_replace_id now broadcasts the received replace ID
2873 packet if it is not broadcast packet already. The router must
2874 broadcast to inform other routers about changed ID.
2876 * Added backpointer to server's router into SilcServer context in
2877 silcd/server_internal.h.
2879 * Fixed silc_server_packet_broadcast to send correct broadcast
2882 * The channel key is now distributed to the local client as soon
2883 as it is received from the router (in router environment) so that
2884 no other packet may be sent for the channel until client has
2887 * silc_server_remove_channel_user now broadcasts the received
2888 Remove Channel User packet if it is not broadcast packet already.
2889 The router must broadcast to inform other routers about removed
2892 * Added users field into SilcPacketContext that is a reference count
2893 of the context. One can increase the reference count by calling
2894 silc_packet_context_dup which is now changed to just increase the
2895 reference count instead of duplicating the data. The reference
2896 count is decresed by calling silc_packet_context_free that will
2897 free the data after the reference count hits zero.
2899 For now on the packet context and everything allocated into it
2900 (including the raw packet from network) must be freed by calling
2901 the new silc_packet_context_free function. Added also new function
2902 silc_packet_context_alloc that must be used now to allocate the
2903 context. This also means that if a routine is asynchronous from
2904 silc_[client/server]_packet_parse_type the packet context must
2905 be duplicated by calling silc_packet_context_dup. Otherwise it
2906 gets free'd after silc_[client/server]_packet_parse_type returns.
2907 Also, one must remember that if packet is duplicated then its
2908 reference count must be decresed by calling the free function as
2909 many times as it was duplicated.
2911 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2912 from both client and server.
2914 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Made joining to a channel working in router environment.
2918 * Cleaned up JOIN command on server side and create function
2919 silc_server_command_join_channel internal routine to make the
2922 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * Changed silc_command_pending list to SilcDList. Also, added
2925 `ident' field to SilcServerCommandPending structure to identify
2926 the reply and to call correct callback.
2928 Added silc_server_command_pending_check function to replace the
2929 corresnponding macro. The silc_command_pending list is not
2932 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2933 to set identifier to previously allocated Command Payload. It
2934 is used to set identifier for command when resending Command
2937 * Added silc_command_payload_encode_payload to encode Command
2938 Payload buffer from SilcCommandPayload structure.
2940 * Added silc_argument_payload_encode_payload to encode Argument
2941 payload buffer from SilcArgumentPayload structure.
2943 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * Changed WHOIS command to support router connection on server side.
2946 The whois request is always sent to router unless the server is
2947 standalone server. After server has received the reply from the
2948 router will it send the reply to the client.
2950 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2951 broadcast received broadcast packet. The function is used only
2952 by router. The broadcast packet is always sent to the router's
2955 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2956 render given ID to printable string, for log files for example.
2958 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2960 * Made basic router to router connections working. At least they
2961 can now connect to each other but nothing really works the way
2962 they are supposed - yet.
2964 * Added new initiator token to RouterConnection configuration
2965 file in silcd/serverconfig.[ch]. It is used to tell whether we
2966 are the initiator to the remote router or whether we'll expect
2967 the other end to connect.
2969 * Moved registering of listener task to silc_server_init, hence
2970 the server starts listenning as soon as it is run, even if it
2971 does not have connections to other routers. Let's see how well
2974 * Changed default connection retry timeouts for more suitable in
2977 * Removed cipher and such arguments from silc_idlist_add_client
2978 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2979 Added new function silc_idlist_add_data to add the keys and stuff
2982 * Added SilcIDListData structure and added it to SilcClientEntry
2983 and SilcServerEntry as their first field in the structure. This
2984 way we can explicitly cast the ID entries to the SilcIDListData
2985 structure and get common data for the entries. In past, we had
2986 to first check what type of connection it is and then cast it to
2987 correct ID entry type. Now, we can directly cast the opaque
2988 pointer to the SilcIDListData (no matter what ID entry it actually
2989 is) and get the data needed.
2991 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2993 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2994 in some circumstances even if threre were timeout tasks, though not
2995 IO tasks, but tasks anyway. Now fixed.
2997 * Defined SilcServerConnection structure to hold connection specific
2998 stuff about directly connected servers and routers. The definition
2999 is currently in silcd/server_internal.h. I thought about having
3000 a bit more important role fro this struct but for now it is used
3001 only when connecting to other server (or router actually).
3003 * Added connecting retry support in server when connecting to
3004 router(s). The retry feature implement exponential backoff
3005 algorithm. Also, added SilcServerParams structure to hold default
3006 parameters for server. For now, it include these retry settings
3007 and are hard coded. After server is moded to be as Silc Server
3008 Library this structure will be more important.
3010 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Changed client librarys channel->clients table to SilcList and
3013 changed code accordingly.
3015 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3017 * Changed client's channel table to SilcList and changed code
3018 accordingly. Also changed SilcChannelClientEntry to include back-
3019 pointer to the channel so that client entry can use that structure
3020 as list as well and we have fast cross-reference to the channel.
3021 This change dramatically decreased the complexity of channel
3022 handling with client entry and vice versa (removed one extra
3023 loop when searching for channel entry from many functions).
3025 * Changed server->sim from table to SilcDList and changed code
3028 * NAMES command can now be used from user interface. It will show
3029 the user list on the channel, neatly.
3031 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3032 Code now saves realname of the user if it becomes available.
3034 * Renamed configure.in to configure.in.pre and made ./prepare
3035 script to automatically add correct version string to
3036 configure.in which it creates from configure.in.pre.
3038 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3040 * NAMES command reply now shows users mode with the nickname when
3043 * Moved silc_client_ch[u]mode[_char] functions from
3044 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3045 place sucks, they are utility functions and should be in some
3048 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3050 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3053 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Added TRQ (efficient deque and list library) into lib/trq. This is
3058 a very good list library that is currently used in the SILC. Defined
3059 SilcList API over the library because I didn't like the API very
3060 much. See lib/trq/silclist.h for the API and examples of how to
3061 use the API. Fixed various places in the code to use the new
3062 SilcList API. The SilcList is meant for lists that has a structure
3063 already defined as a list. It is not suitable to add just some
3064 context to the list (in TRQ, the context is the list actually).
3066 So, I defined SilcDList that can be used for the purpose where
3067 predefined list structure does not exit. This can be used as
3068 such list. Now some context just can be added to the SilcDList.
3069 Currently this list is not used in the SILC just yet, though there
3070 are a lot places where this can replace dynamically allocated
3071 tables and I will fix these places, later, to use SilcDList.
3072 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3073 and use TRQ internally).
3075 Also fixed some annoying warning messages that the original TRQ
3076 code generated. Also minor changes to TRQ's Makefile.in.
3078 * Added support for querying by Client ID to both WHOIS and
3079 IDENTIFY commands into server, as required by the protocol.
3081 * Removed method function pointers from SilcBuffer structure. They
3082 weren't used to anything and just increased the context size for
3083 no good reason. This change also made silc_buffer_alloc and
3084 silc_buffer_free functions inline functions.
3086 * Disabled command flooding detection support until it's fixed so
3087 that it accepts commands in but does not execute them more than once
3090 * Added silc_net_localhost(), to return local hostname, into
3091 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3092 that must be initialized before calling silc_client_init.
3094 * Added new function: silc_server_send_notify_on_channels to send
3095 notify messages to all channels client has joined. It is assured
3096 that the message is sent only once per client.
3098 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3099 lib/silcutil/silcutil.[ch] as silc_format function. The new
3100 function is generic and is used by server as well, not only by
3101 the logging routines.
3103 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3104 the provided version string was not acceptable. Added new function:
3105 silc_ske_check_version into lib/silcske/silcske.h. The function
3106 must be implemented by the application (client or server) and it
3107 does not reside in the SKE library. The function checks the version
3108 string remote end sent.
3110 * Added back pointers (to opaque context and to SilcSocketConnection)
3111 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3113 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3114 duplicate packet context structure.
3116 * Changed `notify' client operation to send same arguments as client
3117 receives from server except for ID's. ID's are mapped to correct
3118 ID entry and that is returned. Also, if channel entry is not sent
3119 by server but the notify is for channel the channel entry is sent
3120 to application (otherwise application doesn't know that it is for
3121 channel (library gets it from packet's Destination ID)).
3123 * Added silc_client_remove_from_channels into client library to
3124 remove a client from all channels it has joined to. Used when
3125 received SIGNOFF notify from server. Added also new function
3126 silc_client_replace_from_channels to replace old ID entry with
3127 new ID entry on all channels. Used when received NICK_CHANGE
3130 * Fixed ID Cache list handling in silc_idlist_get_client in
3131 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3132 to get (or query) client by ID.
3134 * Updated TODO list.
3136 * Added connection authentication status message defined by the
3137 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3138 support for these into the code in client and server side.
3140 * Added generic function silc_client_send_command to send any command
3141 with variable argument list. Application should use this function
3142 to send commands if the command functions provided by the library
3143 does not suite for the application's user interface needs.
3145 * Added new `failure' client operation. Application is notified about
3146 received failure packet if client is executing a protocol. In this
3147 case the protocol's execution has failed.
3149 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3150 is required by the protocol.
3152 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3153 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3156 * Added status flag to SilcSKE object to indicate realtime status
3157 of the SKE protocol.
3159 * Application receives now exactly same command reply arguments as
3160 the library receives from server. However, if ID is received the
3161 corresponding ID entry is returned to the application (eg. Client
3162 ID is mapped to correct SilcClientEntry entry and that is returned).
3163 Changed command_reply client operation due to this change.
3165 * Changed all ID's in commands and in command replys as ID Payloads.
3166 Change affected both client and server side codes.
3168 All ID's sent in SILC network (with execption of ID's in SILC
3169 Packet header) are sent in ID Payload to support variable length
3172 * Server now notifies nick changes and notifies all clients on
3173 the channels about the new nickname (about the new Client ID,
3176 * Implemented CMODE command to change channel modes. Supports all
3177 channel modes defined by the protocol specs except ban and invite
3178 lists. (Also, private channel key mode is supported but support for
3179 setting private channel key in client is missing, thus, this mode
3180 has no effect on client side (except that server requires that the
3181 client uses private channel key and normal channel traffic does not
3184 Also, invite mode works per se, but INVITE command does not work
3185 yet correctly, so you can set channel as invite only channel but
3186 inviting clients to the channel does not work (it is yet to be
3187 thought what's the best way to do it).
3189 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3190 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3191 Implemented CUMODE command to change user's mode on the channel.
3192 Supports all modes defined by the protocol specs.
3194 * Added NAMES command reply to return users modes on the channel.
3196 * Removed unnecessary and slow ciphers from lib/silccrypt.
3198 * Set SO_KEEPALIVE option to connection sockets by default.
3200 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3202 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3203 redefined the Notify Payload into protocol specs.
3205 * Added silc_id_payload_parse_id to get ID directly from raw
3208 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3211 accept searching by Client ID as well.
3213 * Added support for LEAVE and SIGNOFF notify types in client library.
3215 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3216 to parse ID Payload from raw data.
3218 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3220 * Added flags parameter into silc_ske_assemble_security_properties
3221 function in lib/silcske/silcske.[ch].
3223 * Changed notify client operation to fit better for notify messages
3224 sent by server. The notify payload received from server is now
3225 passed to the application (after parsing it to SilcNotifyPayload).
3226 It is application's responsibility to retrieve the arguments
3227 from the payload and show the message the way it wants. The message
3228 sent by server is implementation specific.
3230 * Changed public keys to comply with the protocol specification.
3231 Old public keys are not supported anymore and are not compatible.
3233 * Removed nickname from Channel Payload as the latest draft removed
3234 it. The client must resolve the nickname from the NAMES command
3235 reply received when it joined the channel.
3237 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3239 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * Fixed some errors in protocol specification drafts.
3243 * Created lib/silccore/silcnotify.c to implement Notify Payload
3244 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3245 generic payloads described by protocol specifications. The file
3246 includes implementations for ID Payload and Argument Payload.
3248 * Changed Command Payload implementation to use the new Argument
3249 Payload. Changed command_xxxx_payload to command_payload_xxxx
3250 to comply with SILC coding conventions.
3252 * Added suppport for Argument Payload handling in Notify Payload
3253 implementation as protocol requires it. Added the new support
3254 into server and client lib as well.
3256 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Added support for multiple nicknames on same channel. [n] is
3259 added locally to the nickname if there are more than one same
3260 nicknames on the channel.
3262 * Server now sends all nicknames that matched WHOIS request.
3263 Client also shows the list received from server.
3265 * Added TOPIC command to client side. User can now set and show
3266 current topic on channel.
3268 * Added MOTD command to client and server. Also, server sends the
3269 motd when client connects to the server.
3271 * Changed version strings to comply ISO 8601.
3273 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Fixed protocol error handling in client library. It should now
3276 cope even if the SKE fails for some reason.
3278 * Made new protocol specification drafts for submitting to IETF.
3280 * Implemented TOPIC command to server in silcd/command.c.
3282 * Added two new notify types into lib/silccore/silcnotify.h:
3283 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3284 notify nickname change and topic setting/change on a channel.
3286 * API change of command_reply operation in client library. The
3287 application gets now the status type received from server as well.
3289 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3293 * Cras fixed and optimized the packet handling even further and
3294 it should work now. Minor change to the prototype of function
3295 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3297 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Added new function into lib/silcutil/silcschedule.[ch]:
3300 silc_schedule_with_fd to select() a specified fd. The function
3301 returns after timeout expires or data arrives or goes. The
3302 function is used by packet routines to wait that all data is
3303 received from network.
3305 * Fixed data reading from network in lib/silccore/silcpacket.c.
3306 The code now assures that all data is read from the fd and then
3307 continues packet processing. This was a bug fix since the code
3308 used to drop some data in some circumstances.
3310 * Added new function into lib/silcclient/client.[ch]:
3311 silc_client_start_key_exchange to start key exchange after
3312 connection has been established to server. The code internally
3313 now uses this funtion but its main purpose was to provide it
3314 for applications that perform their own connecting. After
3315 application has created a connection it merely calls this
3316 function to start the key exchange between client and server.
3317 The library takes care of everything else after that.
3319 Updated also lib/silcclient/README to explain the usage of
3322 * Do not send to application information that connection has
3323 been established. Application gets notified it by connect
3326 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3328 * Applied cras's patch to add silc_schedule_one function. The
3329 function runs scheduler once and returns.
3331 * Fixed the scheduler after cras messed it up. The timeout
3332 handling works now as it's supposed to work.
3334 * Added into lib/silccore/ silcnotify.h to include notify
3335 message types support. Changed silc_server_send_notify*
3336 functions, in server.[ch], to support those new notify types.
3337 Added the support for the notify types into client library,
3338 as well. Added new notify client operation into ops.h in
3341 * Changed silc_server_packet_send_to_channel to send normal
3342 packets instead of just channel message packets. The function
3343 is now used to send the notify packets to channels. It is not
3344 used to send channel message packets anymore, as server never
3347 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3348 va_arg()s as it seems to require it nowadays. I guess, if SILC
3349 is compiled with older va_arg() the new code should work anyway.
3351 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3353 * Splitted core library. Core library (lib/silccore) includes
3354 now only SILC protocol specific core (and common) components.
3355 Created new utility library (lib/silcutil) that includes more
3356 generic purpose stuff. The stuff for util library was taken
3357 from the old core library. This was minor and easy split.
3359 * Created SILC Client Library (lib/silcclient) that includes
3360 implementation of the SILC client without user interface. This
3361 was major move from silc/ directory. The code has been changed
3362 so that it is transparent towards the user interface. The
3363 silc/ directory includes now the same user interface as before
3364 and it uses the new client library. Read lib/silcclient/README.
3365 Basicly, the client library performs everything else related
3366 to SILC except user interface handling. Also, configuration
3367 files are considered to be part of user interface and library
3368 does not handle them.
3370 This change also changed a lot of structures, function naming etc.
3371 Most important change was that SilcClientWindow object was
3372 renamed to SilcClientConnection in the client library. Created
3373 also new file lib/silcclient/ops.h. Also added new files
3374 silc/local_command.[ch] and silc/client_ops.[ch].
3376 All these changes were made to make it easier for user interface
3377 designers to create what ever user interface for the SILC client
3380 It is also expected that the server will be moved to lib
3381 directory as well and SILC Server Library will be created;
3382 sometimes in the future.
3384 * Removed Local commands from lib/silccore/silccommand.h as
3385 they are application specific and new client library does not
3386 handle any of those anymore.
3388 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3389 old client implementation in silc/.
3391 * Added support for callback functions in SILC_LOG_* macros.
3392 Application can now set its own callbacks that will be called
3393 instead of using the default functions that will always print
3394 the debug messages to stderr (or stdout). Also, debugging can
3395 now be disabled by setting silc_debug to FALSE and re-enabled by
3396 setting it to TRUE. Note, that logging will still work even
3397 if debugging is disabled.
3399 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3400 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3401 silc_log_reset_debug_callbacks.
3403 * To enable debugging in silc client one must give now -d
3404 option on command line.
3406 * Changed silc_schedule_init to automatically allocate task queues
3407 if they are not allocated before calling it.
3409 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3411 * Added GMP 3.1 into math library.
3413 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3416 a channel in SILC network. The packet is used by servers and
3417 routers to notify other routers that user has left a channel.
3418 This little feature was missing until now. Added the feature
3419 to protocol specification as well.
3421 Added functions: silc_server_send_remove_channel_user and
3422 silc_server_remove_channel_user into server.[ch].
3424 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3425 lib/silccore/silcpacket.h. However, they are not implemented
3428 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Fixed joining to a channel and sending channel messages
3431 between server and router. The channel message sending should
3432 now work inside a cell.
3434 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Fixed the private message sending between server and router.
3437 The private message sending should now work inside a cell.
3439 * Added silc_server_replace_id into server.[ch] to replace
3440 existing ID in the SILC network.
3442 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3443 and silc_idlist_replace_server_id into idlist.[ch] in server.
3445 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Fixed the server to server connections. Server can again now
3448 connect to router. Router to router connections probably does
3451 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3453 * Added dynamic protocol registering support. Now protocols can
3454 registered and unregistered on the fly. Patch by cras.
3456 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Added lib/contrib directory to hold routines that some platforms
3459 don't have but are needed by SILC.
3461 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3462 into lin/contrib to provide getopt() and getopt_long() for
3463 those who don't have it.
3465 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Added AWAY command to client. When away message is set and
3468 client receives a private message packet the client automatically
3469 replies to the sender with the away message.
3471 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3472 bug seemed to be the cause of recent problems when compiling
3475 * Added version detection support to SKE protocol specification
3476 and added the new changes to the SKE implementation as well.
3477 There were other minor changes in the SKE protocol as well.
3479 Many changes in lib/silcske/silcske.[ch] and in
3480 lib/silcske/payload.[ch].
3482 * Added ^U functionality, clear input line. Patch from cras.
3484 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Mainly small bugfixes on core library. Fixed some debugging
3487 logging and buffer overflow in silclog.c.
3489 * Updated config.sub and config.guess on the distribution tree.
3491 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * Added command lagging support in server. Client may execute
3494 commands now only once in two seconds.
3496 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3498 * Optimized packet reception. MAC computation and checking is now
3499 also more optimized. A lot previously duplicated code is now
3500 used as generic by both client and server.
3502 * Fixed key pair generation in clientutil.c
3504 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3506 * Added into lib/silccore/silcbufutil.[ch] new function;
3507 silc_buffer_realloc.
3509 * Moved generic packet sending/encryption functions to
3510 lib/silccore/silcpacket.[ch] from client and server. Some
3511 rewriting of the functions.
3513 * Moved all generic packet reception/decryption functions to
3514 lib/silccore/silcpacket.[ch] from client and server. The
3515 packet processing is now much cleaner in both client and server.
3516 These were major changes in both client and server.
3518 * Created many common functions in server to do packet sending.
3519 Previously code were duplicated a lot, this has been removed
3522 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Rewrote major parts of the ID cache system. Don't know
3525 whether it is better now or not but at least the API is more
3528 * Major rewrite on ID cache stuff on client because of the ID
3529 cache API changes. Added idlist.c to client.
3531 * Also major rewrite on ID cache stuff on server as well.
3532 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3533 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3534 in hand, instead they are all put into the ID cache system now.
3535 All server_idlist_* routines uses ID cache now instead of
3536 traversing its own lists (those lists does not exist anymore).
3537 SilcIDList though still exists. Also, SilcXXXEntry's are
3540 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Finally made the SKE implementation compliant to the protocol
3543 specification. All mp integers are now binary encoded as
3544 opposed being HEX encoded.
3546 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3549 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3550 functions: silc_[encode/decode]_pem. Also added function
3551 silc_encode_pem_file to PEM encode with newlines ('\n') for
3554 * SILC public keys are now encoded either PEM or binary. Same
3555 option is for private keys as well. By default private keys
3556 are binary encoded and public keys PEM encoded. Silly HEX
3557 encoding were removed.
3559 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3560 function to create fingerprints.
3562 * Fixed a bug in SHA1; does not change the original data anymore.
3564 * Partly implemented INFO command on client and server side.
3565 Fixed CLEAR command. Changes to SERVER command; show current
3566 server(s) when giving command without arguments. Added
3567 VERSION command to client.
3569 * Added check to server that unregistered connections cannot
3570 execute commands (unless it is specificly allowed).
3572 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Fixed screen refresh.
3576 * Fixed channel joining bug from client. On some circumstances
3577 client tried to join to a channel it had already joined.
3579 * Added public key verification process into client's protocol.c.
3580 The client now verifies the public key from user and saves
3581 it into ~./silc/serverkeys/ directory.
3583 Added into: clientutil.[ch]: silc_client_verify_server_key.
3585 * Changed SKE protocol's silc_ske_initiator_finish function
3586 to accept callback function that verifies the received public
3587 key. Removed old silc_ske_verify_public_key function.
3589 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3592 silc_pkcs_private_key[_data]_set.
3594 * Made the password and public authentication more cleaner in
3595 server's protocol.c.
3597 * Removed historic and obsolete protocol `channel_auth' from
3598 both client and server.
3600 * Removed wrong way of sending command status messages from
3601 server to client in server's command.c. The old way violated
3602 protocol specification.
3604 Changes to silccore/silccommand.[ch]: removed
3605 silc_command_encode_status_payload -> not needed anymore,
3606 changed silc_command_encode_payload_va to accept extra
3607 argument on variable argument list. The argument type must
3608 now be provided to the function. Also, added new function:
3609 silc_command_encode_reply_payload_va which is same as
3610 normal command_encode_payload_va except command status type
3611 is provided as extra argument.
3613 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3615 * Added ~./silc directory handling. The directory includes the
3616 public and private keys for the client.
3618 Added silc_client_check_silc_dir, silc_client_create_identifier
3619 and silc_client_load_keys.
3621 * Implemented SILC protocol compliant public key. Added public
3622 and private key saving to and loading from files.
3624 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3625 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3626 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3627 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3628 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3630 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3631 silc_pkcs_load_[public/private]_key.
3633 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Added silc_server_get_route (route.[ch]) to get connection
3636 data for the fastest route for given ID.
3638 * Implemented INVITE command on client and server. The command
3639 were re-defined in the SILC Protocol Specification and the
3640 implementation now complies with the specification.
3642 * Implemented PING command on client and server.
3644 * Implemented NAMES command on client and server. The server side
3645 supports currently only normal server not router server yet.
3646 Some changes to NAMES definition in SILC protocol specification.
3648 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * Implemented LEAVE command on client and server.
3652 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3653 again. This change was made to the protocol as well. Server
3654 should not violate the protocol specification anymore.
3656 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3659 was tested. SOCKS4 was not but should work anyway.
