1 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7 * silc_idcache_purge_by_context deletes the entry now by context
8 as it is supposed to do. Affected file lib/silccore/idcache.c.
10 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
11 client is not anymore valid (WHOWAS givens the info) and not
12 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
14 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
16 * Removed the `data' and `data_len' arguments from the ID Cache
17 interfaces and added `name' argument. ID Cache does not handle
18 anymore the binary data only a names associated with given ID.
20 * When hashing a Client ID with silc_hash_id the entire ID is
21 not hashed anymore, instead only the hash of the Client ID is
22 hashed. This way we can access the Client ID from the cache
23 with Client ID but with the hash of the ID (which is a hash of
24 the nickname) as well without any difference in performance.
26 Added also silc_idcache_find_by_id_one_ext to do one on one
27 searching when we have the actual ID. Added also function
28 silc_hash_client_id_compare. The affected files are
29 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
31 * When hashing the name associated with a ID it is always done
32 in lowercase. This way we can access the cache without worrying
33 about case-sensitivity, even though, for example nicknames are
36 * Fixed a bug in server with channel message sending. It put
37 wrong ID type as destination ID. The affected file
40 * silc_idcache_del_by_context now deletes from all hash tables
41 by context. Affected file lib/silccore/idcache.c.
43 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
45 * Changed the client library to use the new ID Cache interface.
46 Changes around the source tree.
48 * Added silc_hash_table_rehash_ext to rehash with specific
49 hash function. Affected file lib/silcutil/silchashtable.[ch].
51 * Added silc_hash_string_compare to compare two strings in the
52 hash table. Affected file lib/silcutil/silcutil.[ch].
54 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
56 * Added new function silc_idcache_del_by_context into the
57 lib/silccore/idcache.[ch].
59 * Changed the server's ID list routines to use the new ID Cache
60 interface. Changes around the source tree.
62 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
64 * Added silc_hash_table_del[_by_context]_ext functions in to the
65 lib/silcutil/silchashtable.[ch].
67 Removed silc_hash_table_find_all* routines and added new
68 silc_hash_table_find_foreach to replace them.
70 Added silc_hash_table_replace_ext function as extended
71 replacing function. Separated the simple hash table interface
72 from the extended hash table interface in the file
73 lib/silcutil/silchashtable.h.
75 * Fixed minor bugs and changed it to use some of the new
76 hash table functions in lib/silccore/idcache.c
78 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
80 * Added new function silc_hash_table_find_all to return all keys
81 in the hash table by the specified key. As the hash table is
82 collision resistant it also makes it possible to have several
83 duplicate keys in the hash table. This function may be used to
84 find all of the keys from the hash.
86 Added user_context arguments to the SilcHashFunction,
87 SilcHashCompare and SilcHashDestructor to deliver user specified
90 Added new fuctions silc_hash_table_find[_all]_ext to do
91 extended lookup with specified hash and compare functions and
92 specified user contexts.
94 Added new function silc_hash_table_add_ext to add the key
95 with specified hash function and user context.
97 Added new function silc_hash_table_foreach to traverse all
98 entrys in the hash table. Added SilcHashForeach callback
101 Added new function silc_hash_table_del_by_context to delete
102 the entry only if the context associated with the key matches.
104 Affected files are lib/silcutil/silchashtable.[ch].
106 * Removed silc_hash_[server/client/channel]_id and added just
107 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
108 silc_hash_id_compare to compare two ID's using as the hash table
109 comparison function. Added also silc_hash_data to hash
110 binary data and silc_hash_data_compare to compare it.
112 * Removed silc_idlist_find_client_by_hash as it is not needed
113 anymore. Affected file silcd/idlist.[ch].
115 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
116 to use internally the SilcHashTable. The new ID Cache is a lot
117 faster than the old one. Some of the ID Cache interface was also
118 rewritten and obsolete and stupid functions were removed.
120 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
122 * Added entry_count field to the SilcHashTable to keep the number
123 of the entries in the table. Implemented the function
124 silc_hash_table_rehash. Added new function
125 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
127 Fixed a minor bug in silc_hash_table_free.
129 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
130 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
131 into the lib/silcutil/silcutil.[ch].
133 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
135 * Implemented a collision resistant hash table into the
136 lib/silcutil/silchashtable[ch]. See the header and the source
137 for the SilcHashTable API.
139 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Merged dotconf version 1.0.2 into lib/dotconf.
143 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
145 * Do not compile anything in lib/silcsim/* if the SIM support
146 is not enabled. The tree should now compile without problems
149 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
151 * Compiled the SILC under cygwin. Compiled and tested briefly
152 without problems. More tests needed. The SIMs didn't compile
155 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
157 * Fixed possible crash in silc_get_username in the
158 lib/silcutil/silcutil.c.
160 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
162 * Fixed a va_arg in silc/client_ops.c.
164 * Oops, RC5 routines were named AES and caused some problems
165 when not using SIM's. Affected file lib/silccrypt/rc5.c.
167 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
169 * Added new SilcIDIP structure into the lib/silccore/id.h and
170 replaced the old `ip' fields from all SILC ID's to that type.
171 This is a step towards IPv6 support.
173 The silc_id_get_len takes now the ID as an extra argument.
174 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
175 both IPv4 and IPv6 based ID's.
177 The affected files are lib/silccore/id.[ch] and other files
178 around the tree using these routines.
180 * Removed the ID length arguments in server from various
181 silc_server_send_notify_* routines -> they are not needed
184 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
186 * Fixed memory leak in silc_encode_pem_file in the file
187 lib/silcutil/silcutil.c.
189 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
191 * Check minor version as well in the SKE. Affected files are
192 silcd/protocol.c and lib/silcclient/protocol.c.
194 * Added --identifier option to the server so that an identifier
195 can be when creating the public key for the server. Affected
196 file is silcd/silcd.c.
198 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
199 lib/silccrypt/silcpkcs.c.
201 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
203 * Register default ciphers and stuff when using -C option with
204 the server. Affected file sildc/silcd.c.
206 * Put back the servers public key filename format, it is better
207 than the new one. For now, the client keys are saved with the
208 new filename format. The affected file silc/client_ops.c.
210 * Implemented the Cipher API for the rest of the ciphers that
211 did not implement it or implemented it the wrong way.
213 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
215 * Register default ciphers and stuff when using the -S option
216 in the client. Affected file silc/silc.c. Same also when
217 creating new key pair with -C option.
219 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
221 * Fixed the silc_verify_public_key client operation function to
222 save the public keys differently. The fingerprint is now
223 used as filename and not the hostname. This way also the
224 client keys are saved uniquely and not with hostnames. The
225 affected file is silc/client_ops.c.
227 * Trimmed the silc_hash_fingerprint function to remove extra
228 whitespaces from the end of the fingerprint. The affected
229 file is lib/silccrypt/silchash.c.
233 * Added silc_cipher_register_default function to register all
234 default ciphers. It can be used when configuration files
235 does not exist and the application does not want any specific
236 ciphers in any specific order.
238 The SilcDList is now used as silc_cipher_list dynamically
239 allocated cipher list. Removed the static list all together
240 and now all ciphers must be allocated to the dynamic list.
241 The silc_cipher_alloc routine was changed to check only the
244 All silc_cipher_* routines that used to return int returns
247 The affected files lib/silccrypt/silccrypt.[ch].
249 * The same thing was done to silc_hash_* as for silc_cipher_*
250 routines. Affected files lib/silccrypt/silchash.[ch].
252 * The same thing was done to silc_pkcs_* as for silc_cipher_*
253 routines. Affected files lib/silccrypt/silcpkcs.[ch].
254 Added also silc_pkcs_[un]register[_default] functions.
255 Removed the data_context from the PKCS API.
257 * Added silc_hmac_register_default function to register default
258 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
259 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
260 to unregister all hmacs at once.
262 * Register the default ciphers, hash functions, PKCSs and HMACs
263 if client's configuration file does not exist. The affected
266 * The client did not load the hash functions from the SIM
267 modules at all. Added support for this. Affected file is
270 * When decoding public key with silc_pkcs_public_key_decode, check
271 the supported algorithm only if PKCS are registered. Affected
272 file lib/silccrypt/silcpkcs.c. The same was done with the
273 silc_pkcs_private_key_decode.
275 * Fixed the SILC List routines to keep the list always in order.
276 It used to change the list's order when traversing the list but
277 not it preserves the order. Affected file lib/trq/silclist.h.
279 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
281 * Added the client library to use the SilcSocketConnection's
282 reference counter (by silc_socket_dup) to prevent the bug that
283 the socket object may be freed underneath async operation.
285 * The name resolv library checking fixes in the configure.in.pre.
288 * Created new version of the protocol drafts for future
289 development. The -03 drafts are the ones that will be changed
290 in the trunk now and the -02 will remain as they are.
292 * Send list of CUMODE notifys to the router when announcing
293 the channel users to the router. Affected file silcd/server.c.
294 If the router receiving channel founder CUMODE for a channel
295 that already has channel founder it will send CUMODE notify
296 to the sender to remove the channel founder rights from the
297 announced client. Affected file silcd/packet_receive.c.
299 * The CUMODE notify may now use Server ID as well as the entity
300 who changes the mode. Updated protocool specs.
302 * Updated INSTALL and README files.
304 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
306 * New web pages in the http://silc.pspt.fi. The pages was
311 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
313 * Implemented the [DenyConnectin] config section in the server.
314 Added silc_server_config_denied_conn to check whether incoming
315 connection is denied. Affected file silcd/serverconfig.[ch].
317 * Do not check the ports when checking the incoming configuration
318 data if the port is 0, meaning any. Affected file is
319 silcd/serverconfig.c.
321 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
323 * Fixed buffer overflow in silc_string_compare in the file
324 lib/silcutil/silcutil.c.
326 * Fixed double free in silc_server_command_leave in the file
329 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
331 * Fixed the version checking in the server. Affected file is
334 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
336 * Fixed the configuration data fetching when accepting new
337 connections in the server. Affected file silcd/server.c.
339 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Added `sender_entry' argument to the function
342 silc_server_packet_relay_to_channel so that we can check
343 whether some destination actually belongs to the same route
344 the sender belongs (ie, we must not resend the packet to the
345 sender). Affected file silcd/packet_send.[ch].
347 * Added `servername' field to the SilcClientEntry in the server
348 to hold the name of the server where client is from. Affected
349 file is silcd/idlist.h.
351 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * Moved the channel message encrypting in the router betwen
354 router connections from silc_server_channel_message to the
355 silc_server_packet_relay_to_channel since we want to check
356 whether we have anybody channel before encrypting anything.
357 Affected files silcd/packet_[receive/send].c.
359 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
361 * Fixed the [AdminConnection] server config section to support
362 multiple entries. Affected file silcd/serverconfig.c.
364 * Added support into the server to check the validity of the
365 incoming connection before executing any KE or authentication
368 * The connection configuration is now saved to the KE and
369 connection auth protocol contexts and not fetched anymore in
370 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
372 * The local hosts listenning address and port is also resolved
373 now when starting the server. We want to have the socket object
374 to include the real address and port for the listener. Added
375 new function silc_net_check_local_by_sock into the files
376 lib/silcutil/silcnet.[ch].
378 * Fixed a broadcast bug in server -> do not broadcast if we
381 * Fixed a routing bug. Do not route broadcast packets ever.
382 Broadcast packets must be processed always and not routed since
383 they may be destined to some other host than yourself and thus
384 would get routed without no good reason. Affected file is
387 * Added function silc_server_config_is_primary_route to check
388 whether primary router connection has been configured (a router
389 configuration that we are initiating). If there is not, we
390 will assume that there is only two routers in the SILC network
391 and we will use the incoming router connection as our primary
392 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
394 * Changed the order of the broadcasting. Broadcast _after_ the
395 packet has been processed not before. Affected file is
398 * Fixed a [ClientConnection] parsing bug. The port was never
399 parsed correctly thus resulting to port 0. Affected file
400 silcd/serverconfig.c.
402 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
403 argument and did not set the broadcast packet flag. Affected
404 file silcd/packet_send.c. Fixed same bug in the function
405 silc_server_send_notify as well.
407 * If we receive NEW_ID packet for our own ID in the server, ignore
410 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
414 * Removed the nickname from the Private Message Payload.
415 Updated the code and the protocol specs.
417 * Updated protocol specs for submitting to the IETF.
419 * Tweaked the Random Number Generator a bit. Affected file
420 lib/silccrypt/silcrng.c. Exported a new function
421 silc_rng_[global]_add_noise which can be used to add more
424 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
426 * Do not parse packets with different timeout when protocol
427 is active -> may cause problem with rekey. Affected file
430 * When server receives signoff notify it must not create
431 new channel key if the client is on any channels since the
432 sender of the signoff notify will create it.
434 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
436 * Added printing of error messages during SKE protocol from the
437 failure packet sent by server during SKE. Affected file
440 * Removed the client's failure_callback handling with timeout
441 and handle it immediately when received.
443 * The SKE library returned wrong type in SUCCESS and FAILURE
444 packets. They must be 32 bit MSB not 16 bit MSB.
446 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
448 * Ok, rewrote the logic of the re-key and now it seems to work.
449 I tested it on high traffic with frequent re-keys without
450 problems. Added hmac_receive (and renamed hmac to hmac_send)
451 in SilcClientConnection in lib/silcclient/client.h and
452 in SilcIDListData in silcd/idlist.h. Also, removed the
453 SilcPacketParserContext's cipher and hmac fields as they are
454 not needed anymore and actually caused some problems when
455 the ciphers and hmac's changed underneath the packet parser.
457 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
459 * If re-key protocol is active then process the incoming packets
460 synchronously since we must assure that icoming packets encrypted
461 with the old key is processed before the new keys is set to
462 use. This is true other packets than for REKEY packets.
463 Affected file silcd/server.c. The same was done to client library
464 as well, affected file lib/silcclient/client.c.
466 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
468 * Fixed bug in client and server to accept the force send if
469 the packet is send from silc_[server/client]_packet_process
470 function. Otherwise the packets are never delivered, oops.
472 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
474 * Disable force sending of packets when REKEY protocol is active.
475 We must assure that no packet is sent directly when rekey is
476 performed. All packets must be sent through packet queue.
477 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
478 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
479 function is silc_[server/client]_packet_send_real to check
482 * Replaced the SIM paths from example config files to
483 /usr/local/modules. Also, make install creates now
484 /usr/local/silc/logs directory to hold all the SILC server
487 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
489 * Made the configure.in.pre work on Solaris. Patch by salo.
491 * Made all ciphers compatible with non-x86 machines. Defined
492 CBC mode macros into lib/silccrypt/ciphers_def.h.
494 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
496 * Fixed the make install.
498 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
500 * When MAC computation fails the silc_packet_decrypt returned 0
501 even though it was supposed to return -1. Fixed this. The
502 affected file is lib/silccore/silcpacket.c.
504 * Do not replace the config files in /etc/silc (in make install)
505 if they already exist. Affected file ./Makefile.am.
507 * Do not send re-key packets immediately but through packet queue.
508 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
510 * Changed silc_net_check_host_by_sock to return FALSE if the
511 IP/DNS could not be resolved. Though, it returns the IP address
512 now even if it could not resolve it (but returns also FALSE).
513 Affected file lib/silcutil/silcnet.[ch].
515 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
517 * Added silc_pkcs_decode_identifier to decode the public key's
518 identifier. Affected file lib/silccrypt/silpkcs.[ch].
519 Added also silc_pkcs_free_identifier. Added also new context
520 SilcPublicKeyIdentifier.
522 * Added -S option to the silc client. It is used to dump the
523 contents of the specified public key file.
525 * Changed the PKCS api to return the public key length when
526 setting the public key.
528 * Fixed a fatal bug in the public and private key file loading.
529 Affected file lib/silccrypt/silcpkcs.c.
531 * Execute the packet parsing for client with zero (0) timeout
532 if the protocol is active. Affected file silcd/server.c.
534 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Made the key generation options to the silcd program. Added
537 -C option, equivalent to client's option.
539 * Added new [ServerKeys] config section to the server. It
540 configures the server's public and private key.
542 * Defined generic Public Key Payload into the protocol
543 specification to send specific type of public keys and
546 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
547 public key or certificate.
549 * Implemented the GETKEY command to the server and to the
550 client library and on user interface.
552 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
554 * Made preliminary `make install' work.
556 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
558 * Added SilcServerRekey context into silcd/idlist.h.
560 * Added the PFS support as defined in the specification to the
561 SKE protocol. Affected files lib/silcske/*.c.
563 * Added `ske_group' field to the SilcServerRekey context to hold
564 the number of the SKE group that is used with PFS in re-key.
565 Affected file silcd/idlist.h.
567 * Added PFS re-key support to the server. Affected file is
570 * Added silc_protocol_cancel to cancel execution of the next
571 state of the protocol. Affected file is
572 lib/silccore/silcprotocol.[ch].
574 * Added the re-key support with and without PFS to the client
575 library. Re-key is performed once in an hour, by default.
577 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
578 Added silc_client_rekey_callback and silc_client_rekey_final.
579 Affected files are lib/silcclient/protocol.[ch] and
580 lib/silcclient/client.[ch].
582 * Removed the `hmac_key' and `hmac_key_len' fields from the
583 SilcClientConnection structure; not needed. Affected file is
584 lib/silcclient/client.h.
588 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
590 * Do not ask whether user wants to use the negotiated private key
591 for private messages, just use it. Affected file is
592 silc/local_command.c.
594 * Added `send_enc_key' and `enc_key_len' fields to the
595 SilcIDListData structure since they are needed in the re-key
596 phase. Affected file is silcd/idlist.[ch].
598 * Implemented the simple re-key protocol into the server.
599 Affected files silcd/server.c and silcd/protocol.[ch]. The
600 re-key will be performed once in an hour, by default.
602 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
603 Added silc_server_rekey, silc_server_rekey_callback and
604 silc_server_rekey_final.
606 * Removed Tunneled flag from the protocol. Updated the code
607 and the specifications.
609 * Adde `pfs' field to the SilcIDListData to indicate whether
610 the PFS is to be performed in the re-key. Affected file is
613 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
615 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
616 int64 of at least the xintXX size. If void * is less that 4
617 bytes uint32 * will be used. Defined bool as boolean.
619 * Changed _ALL_ unsigned long and unsigned int to uint32,
620 unsgined short to uint16 in the source tree.
622 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
623 not handle clients that has entry->data.registered == FALSE.
624 They are not in the network anymore. Affected file is
627 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
629 * Implemented the sending of the SERVER_SIGNOFF notify in the
630 server. Affected file is silcd/server.c.
632 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
633 Added also silc_notify_payload_encode_args into the
634 lib/silccore/silcnotify.[ch].
636 * Implemented ther SERVER_SIGNOFF notify handling in the server.
637 Affected file silcd/packet_receive.c.
639 * Implemented the SERVER_SIGNOFF notify handling in the client
640 library. Affected file lib/silcclient/client_notify.c. Also,
641 implemnted the printing of the SERVER_SIGNOFF info to the
642 application. Affected file silc/client_ops.c.
644 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
645 if the deleting was successful. Affected file silcd/idlist.[ch].
647 * Added support for public key authentication in the connection
648 authentication protocol in the client library. Affected file
649 lib/silcclient/protocol.c.
651 * Changed the server's silc_idlist_get_clients_by_* interface
652 to support already allocated array so that new entries may be
653 added to pre-allocated array. Affected file silcd/idlist.[ch].
654 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
657 * All command reply functions in the server now calls the
658 pending command callback even if error occured. This way the
659 error will be delivered to the client as well. Affected files
660 silcd/command.c and silcd/command_reply.c.
662 * Fixed INFO command to return local server's info if no server
663 was provided. Affected file lib/silcclient/command.c.
665 * Removed RESTART command for good. Updated the code and the
668 * Rewrote parts of the task system. It is a bit simpler now.
669 Removed unsued task priorities. The affected files are
670 lib/silcutil/silctask.[ch].
672 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
674 * Moved the USERS printing from the library to the application.
675 Affected files lib/silcclient/command.c and silc/client_ops.c.
677 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
681 * Added channel key re-key support. The re-key is perfomed
682 only by the router and is done once in an hour. Added `rekey'
683 field to the SilcChannelEntry in the server. Affected files
684 silcd/server.c and silcd/idlist.h.
686 * Added silc_task_unregister_by_context into the file
687 lib/silcutil/silctask.[ch].
689 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
691 * Added SILC_UMODE_GONE mode to indicate when the client is not
692 present in the SILC network. Added also support to the local
693 command AWAY that will set this mode. Added support of showing
694 "xxx is gone" in WHOIS command. The USERS command shows the
697 * Fixed setting server and router operator privileges in the
698 server's UMODE command. Affected file silcd/command.c.
700 * Merged the SKE KE1 and KE2 payloads into one payload. The
701 new KE payload is equivalent to the old KE2 payload.
703 Cleaned up the SKE Start Payload parsing. It now uses the
704 simple buffer unformatting to do the parsing. A lot faster
707 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
708 to the SKE that is used to indicate whether both of the SKE
709 parties should perform authentication. By default only the
710 responder performs authentication. By setting this flag also
711 the initiator must do authentication. By default it is unset
712 since in normal SKE case, client to server connection, only
713 the responder should do authentication. When doing SKE between
714 two clients both should perform authentication. Updated the
715 code and the protocol specs.
717 * A little fix to IDENTIFY command in the server. Search the
718 client first by hash not nickname. Affected file is
721 * Fixed the silc_client_close_connection to support closing
722 the client to client connections wihtout deleting too much
723 data. Affected file lib/silcclient/client.c.
725 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
726 are received if protocol used to be active but is not anymore
727 the application would crash due to NULL pointer dereference.
728 Affected files silcd/server.c and lib/silcclient/client.c.
730 * Added `hash' field to the SilcClientConnection to include
731 the hash function negotiated in the SKE protocol.
733 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
734 to set the channel founder authentication data. A client can
735 claim the founder rights later by providing the authentication
736 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
737 This way the channel founder can regain the channel founder
738 privileges even it is left the channel. This works only on
739 local server and the client must be connected to the same
740 server to be able to regain the founder rights. Updated the
741 protocol specs accordingly.
743 Added support to the CMODE command in the client to set the
744 founder auth data. Read the README to see how to set it.
746 Added support to the CUMODE command to claim the founder
747 rights. Read the README to see how to do it.
749 Added support for the founder authentication to the Channel
750 Entry in the server. Affected file silcd/idlist.h.
752 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
753 server's CMODE command. Affected file silcd/command.c.
755 * Added the following new functions into lib/silccore/silcauth.[ch]:
756 silc_auth_get_method and silc_auth_get_data.
758 * The server now saves the remote hosts public key to the
759 SilcIDListData pointer. Affected file silcd/protocol.c.
761 * The normal server now does not remove the channel entry from
762 the cache if the founder authentication data is set. It used
763 to remove it if the founder was the last one on the channel on
764 the server and left the channel. The auth data is saved and
765 if the channel is re-joined later the old entry is used with
766 the old auth data. Affected files silcd/command_reply.c and
769 * Removed the `pkcs' field from the SilcIDListData structure
770 in the server; it is not used. Affected file silcd/idlist.h.
772 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
774 * Fixed packet processing on slow links. Partial packets were
775 never re-processed because the incoming data buffer was cleared
776 by the application. Application must not directly clear the
777 sock->inbuf, the packet processing routines handle it. Fixed
778 this in client library and in server.
780 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
782 * Fixed the WHOIS and IDENTIFY send reply function to really
783 check whether to send list or just one entry. Affected file
786 * Cleaned up the LEAVE command's channel key distribution. The
787 affected file silcd/command.c.
789 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
790 can enforce the channel mode as well. In that case the ID
791 includes the ID of the server. The code now enforces the
792 mode change if the router have different mode than the server.
794 * The notify client operation with CMODE_CHANGE notify can now
795 return NULL client_entry pointer if the CMODE was not changed
796 by client. Application must check for this.
798 * Added <Server ID> argument to INFO command to support server
799 info fetching by Server ID.
801 * Added silc_server_announce_get_channel_users to get assembled
802 packets of channel users of the specified channel. Affected
803 file silcd/server.[ch].
805 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
806 was freed underneath the ID Cache.
808 * Re-announce clients when the server received CHANNEL_CHANGE
809 notify from the router. Affected file silcd/packet_send.c.
811 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
813 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
814 crashed since it did not handle the fact that there is no cipher
815 called "3" and didn't check the error condition. Now fixed.
817 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
818 flag. It can be used to send message requests.
820 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
822 * Implemented the RESTART command in the client.
824 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
825 notice type messages. Added notice printing to the user
828 * The channel keys are not re-generated if the channel's mode
829 is PRIVKEY, ie private key on the channel exists. Affected
830 files silcd/server.c and silcd/command.c.
832 * Fixed a little bug in channel message delivery when channel
833 private keys are set in the server. Affected file is
836 * Changed the setting on channel->on_channel = TRUE from the
837 silc_client_save_channel_key to the JOIN command reply. The
838 key payload is not received if the private channel key is set.
839 Affected file lib/silcclient/command_reply.c and the
840 lib/silcclient/client_channel.c.
842 * When the CMODE_CHANGE notify is sent and the channel private
843 key mode is removed the channel key must be re-generated in
844 other cells as well. Added this support for the router in the
845 silcd/packet_receive.c.
847 * Added new local command NOTICE to send notice message on
848 channel. Affected file silc/local_command.[ch].
850 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
852 * Added new local command ME to the client. It is used to send
853 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
854 some action. Affected file silc/local_command.[ch].
856 * Changed channel_message and private_message client operations
857 to deliver the message flags to the application. Added also
858 the `flags' arguments to the silc_client_send_channel_message
859 and silc_client_send_private_message functions. Affected file
862 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
864 * Redefined the Private Message Payload to support private message
865 keys and to support the new private message flags. Updated
866 the protocol specs. Flags makes it possible to have for example
869 * Added new type SilcPrivateMessagePayload and defined an API
870 for it in the lib/silcclient/silcprivate.[ch].
872 * Tested private message private keys successfully. Tested the
873 private message key set, unset and list commands with the new
876 * Redefined the Channel Message Payload to include the channel
877 message flags (equal with private message flags) to support
878 for example CTCP style messages.
880 * Defined some of the message (for channel and private message)
881 flags. Updated the protocol specs and added the flags to the
882 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
884 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * Added SilcKeyAgreementStatus type to the key agreement routines
887 to indicate the current status and error if one occured.
888 The status types are defined in the lib/silcclient/silcapi.h.
890 * Added new local command KEY that is used to set and unset private
891 keys for channels, set and unset private keys for private messages
892 with remote clients and to send key agreement requests and
893 negotiate the key agreement protocol with remote client. The
894 key agreement is supported only to negotiate private message keys,
895 it currently cannot be used to negotiate private keys for channels,
896 as it is not convenient for that purpose.
898 * Fixed a minor pending callback setting bug in the function
899 silc_client_get_client_by_id_resolve, now the function works.
900 Affected file lib/silcclient/idlist.c.
902 * Added function silc_net_get_local_port to get local bound
903 port by socket. Added to lib/silcutil/silcnet.[ch].
905 * Added `sockets' and `sockets_count' fields to the SilcClient
906 object. They hold the sockets of the listenning sockets in
907 the client. Listenning sockets may be for example the key
908 agreement server. Affected file lib/silcclient/client.[ch].
909 Added functions the silc_client_add_socket and the
910 silc_client_del_socket. They are exported to the application
913 * Added ~./silc/clientkeys to support other client's public keys.
915 * Renamed verify_server_key client operation to verify_public_key
916 and added one argument to indicate the type of the connection
917 (server, client etc.).
919 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
921 * Added silc_server_connection_auth_request to handle the
922 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
923 silcd/packet_receive.[ch].
925 * Added silc_server_send_connection_auth_request into the
926 silcd/packet_send.c to send the connection auth request packet.
928 * Cleaned up the silcd/protocol.c a bit and fixed some memory
931 * Fixed the public key authentication in responder side in the
932 server. The `auth_data' pointer includes the SilcPublicKey
933 not the path to the public key. Affected file silcd/protocol.c.
935 * Implemented the public key authentication in the initiator side
936 in the server. Affected file silcd/protocol.c.
938 * Removed the [RedirectClient] config section from the server
939 configuration. Is not needed and I don't want to implement it.
941 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
943 * Cleaned up the CMODE command in the server. It now works
944 correctly and supports all the modes defined in the protocol.
945 Affected file is silcd/command.c.
947 * Added `hmac_name' field to the SilcChannelEntry in the server
948 to hold the default HMAC of the channel. It can be set when
949 creating the channel (with JOIN command). Affected files
952 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
953 type to indicate the change of the current cipher and hmac
954 on the channel. Client can safely ignore the <cipher> argument
955 (if it chooses to do so) since the CHANNEL_KEY packet will
956 force the channel key change anyway. The <hmac> argument is
957 important since the client is responsible of setting the new
958 HMAC and the hmac key into use.
960 * Fixed the CMODE command in the client library as well.
962 * Tested CMODE command in router environment successfully.
964 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
966 * Show the version of the remote client (or server) when connecting
967 to the server. It is logged to the log file. Affected file
970 * Fixed the KILLED notify handling in the client library. The
971 client must be removed from all channels when receiving the
974 Also, do not remove the client entry when giving the KILL
975 command but when the KILLED notify is received.
977 * Removed silc_idlist_find_client_by_nickname from the server.
978 Not needed anymore. Affected files silcd/idlist.[ch].
980 * Implemented the CHANNEL_CHANGE notify type handling to the
981 server. Affected file silcd/server.c.
985 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Added silc_server_send_notify_invite to send the INVITE
988 notify between routers.
990 * Implemented the INVITE command correctly to the server.
992 * Implemented the INVITE notify type handling in the server.
994 * Implemented the INVITE command to the client library and on the
997 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
999 * Added function silc_server_get_client_resolve to find the
1000 client entry by ID from all ID lists and then resolve it
1001 (using WHOIS) if it cannot be found. Affected file is
1004 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1006 * Implemented the BAN command to the client library.
1008 * The JOIN command in the server now checks the invite list
1011 * Changed the silc_command_reply_payload_encode_va and the
1012 silc_command_payload_encode_va to support that if argument is
1013 NULL it ignores and checks the next argument. Affected file
1014 lib/silccore/silccommand.c.
1016 * Added silc_server_send_notify_ban to send the BAN notify
1017 type between routers.
1019 * Chaned the silc_notify_payload_encode to support that if
1020 argument is NULL it ignores and checks the next argument.
1021 Affected file lib/silccore/silcnotify.c.
1023 * Tested ban lists in router environment successfully.
1025 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Implemented BAN command to the server, in silcd/command.[ch].
1029 * Removed the BAN and INVITE_LIST modes from the CMODE command
1032 * Added function silc_string_match to regex match two strings.
1033 Affected files lib/silcutil/silcutil.[ch].
1035 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1037 * Redefined parts of the SilcChannelEntry in the server to support
1038 the new ban and invite lists.
1040 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1042 * Redefined the INVITE command. The same command can be used to
1043 invite individuals to the channel but also to manage the invite
1044 list of the channel (to add to and remove from the invite list).
1045 Updated the protocol specs.
1047 * Added new command SILC_COMMAND_BAN that can be used to manage
1048 the ban list of the channel. Updated the protocol specs.
1050 * Removed the channel modes: the SILC_CMODE_BAN and the
1051 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1052 in the CMODE command. The equivalent features are now available
1053 using INVITE and BAN commands. Updated the protocol specs.
1055 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1056 in the network about change in the current ban list. The notify
1057 type is not used by the client.
1059 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1060 support the invite lists.
1062 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1064 * Added new function silc_string_regexify that converts string
1065 including wildcard characters into regex string that can
1066 be used by the GNU regex library. Added into the file
1067 lib/silcutil/silcutil.[ch].
1069 Added silc_string_regex_combine to combine to regex strings
1070 into one so that they can be used as one regex string by
1071 the GNU regex library. Added into the file
1072 lib/silcutil/silcutil.[ch].
1074 Added silc_string_regex_match to match two strings. It returns
1075 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1077 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * Imported GNU regex to the soruce tree into lib/contrib.
1080 Fixed some compiler warning from the regex.c.
1082 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1084 * Fixed MOTD command in the server to work in router environment.
1086 * Fixed the MOTD command in the client library to support
1087 the server argument in the command.
1089 * Added `nickname_len' argument to the silc_idlist_add_client
1090 in the server, as the `nickname' argument may be binary data
1093 * Added silc_idlist_get_channels to return all channels from
1096 * Implemented LIST command to the server. Affected file is
1099 * Implemented the LIST command to the client library and on the
1102 * Added [<user count>] argument to the LIST command reply.
1103 With private channels the user count is not shown.
1105 * Updated TODO and README.
1107 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * The client entry's data.registered must be TRUE even with
1110 global client entry on global client list. The data.registered
1111 is used to check whether the client is anymore in the network,
1112 for example with WHOWAS command so it must be valid.
1114 * Fixed the WHOWAS command in the server. It now actually works
1115 in router environment. Added function into silcd/command_reply.c
1116 silc_server_command_reply_whowas_save.
1118 * Added silc_idlist_purge function to the silcd/idlist.c
1119 to periodically purge the ID Cache.
1121 * Fixed INFO command in the server. It works now in router
1122 environment. Added <server name> argument to the INFO command
1123 reply. Updated the protocol specs.
1125 * Fixed minor bug in silc_idcache_purge to not purge if the
1126 expire value is zero.
1128 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1129 they were buggy because of the WHOWAS information.
1131 * Fixed local command MSG to handle the async resolving of
1132 the remote client properly. It used to fail the first MSG.
1133 Affected file silc/local_command.c.
1135 * Added `data_len' field to SilcIDCache context.
1137 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1139 * Update TODO. Todo in commands in the server.
1141 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1144 used by routers as broadcast packet to inform other routers
1145 about the changed user mode.
1147 Implemented the notify handling in the server. Affected file is
1148 silcd/packet_receive.c. Added the function
1149 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1151 * Added new generic Channel Payload and deprecated the New Channel
1152 Payload. The New Channel Payload is now the generic Channel
1155 * Added new argument `mode' to the silc_server_send_new_channel
1156 as it is required in the Channel Payload now.
1158 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1159 and created a new and real SilChannelPayload to represent the
1160 new generic Channel Payload. Implemented the encode/decode
1161 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1163 * Added silc_server_get_client_channel_list to return the list
1164 of channels the client has joined for WHOIS command reply.
1165 Affected file silcd/server.[ch].
1167 * Implemented the channel list sending in the WHOIS command reply
1168 in server and in the client.
1170 Implemented the channel list displaying on the user interface
1171 as well. Affected file silc/client_ops.c.
1173 * Added silc_channel_payload_parse_list to parse list of Channel
1174 Payloads. It returns SilcDList list of SilcChannelPayloads.
1175 Client for example can use this function to parse the list of
1176 channels it receives in the WHOIS command reply. The caller
1177 must free the list by calling silc_channel_payload_list_free.
1178 Affected files lib/silccore/silcchannel.[ch].
1180 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Added one new argument <user mode> to the WHOIS command reply
1183 to return the mode of the user in SILC. Updated the protocol
1186 Implemented it to the server and client.
1188 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Fixed the mode printing on the user interface on joining.
1191 Affected file silc/client_ops.c.
1193 * Implemented the UMODE command and user modes in general to the
1194 client library and to the user interface.
1196 * Implemented the UMODE command to the server.
1198 * The server now sends UNKNOWN_COMMAND error status if client sends
1199 unknown command. Affected file silcd/command.c.
1201 * All server commands now handle the command identifier the right
1202 way when sending the command reply to the client. The client can
1203 use to identify the command replies with the identifier.
1205 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Added silc_server_get_client_route to resolve the route to
1208 the client indicated by the client ID. Affected file is
1211 * Added silc_server_relay_packet as general function to relay
1212 packet to arbitrary destination. This deprecates functions
1213 like _send_private_message_key, _relay_notify etc. Affected
1214 file is silcd/packet_send.[ch].
1216 Removed silc_server_send_key_agreement,
1217 silc_server_send_private_message_key and
1218 silc_server_packet_relay_notify functions from the file
1219 silcd/packet_send.[ch].
1223 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1224 server. Affected file silcd/packet_receive.[ch].
1226 * Implemented the KILL command to the client. Implemented the
1227 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1228 Affected files lib/silcclient/command[_reply].c and
1229 lib/silcclient/client_notify.c. Implemented the KILL notify
1230 printing in the user inteface.
1232 * Fixed a lot silc_parse_nick memory leaks from the client
1233 library in the file lib/silcclient/command.c.
1235 * Changed the silc_server_send_notify_on_channels's `sender'
1236 argument from SilcSocketConnection to SilcClientEntry to
1237 check the sender as entry and not as connection object and not
1238 to send to the client provided as argument. The affected file
1239 is silcd/packet_send.[ch].
1241 * The notify packets that are destined directly to the client used
1242 to not to be processed by the server. Now changed that and the
1243 server processes all notify packets. After relaying the packet
1244 to the client the notify packet is processed in the server.
1246 * The silc_server_free_client_data now checks whether there is
1247 pending outgoing traffic for the client and purges the data to
1248 the network before removing the client entry.
1250 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1252 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1253 an client is killed from the SILC Network. Updated the protocol
1256 Added new function silc_server_send_notify_killed to the
1257 silcd/packet_send.[ch].
1259 * Added function silc_server_packet_relay_notify to relay notify
1260 packets that are destined directly to a client. In this case
1261 the server does not process the notify packets but merely relays
1262 it to the client. Affected file silcd/packet_send.[ch].
1264 Added also silc_server_packet_process_relay_notify to check
1265 whereto relay the notify. Affected file is
1266 silcd/packet_receive.[ch].
1268 * Implemented the KILL command to the server.
1272 * Added the backup schema desgined last fall to the protocol
1273 specs for everyone to see. The specification is in the
1274 *-spec-xx.txt draft and the packet type definitions for the
1275 backup routers is in *-pp-xx.txt draft. Thusly, added also
1276 new packet type SILC_PACKET_CELL_ROUTERS.
1278 * A big security problem in the implementation discovered. The
1279 signoff of an client did not cause new channel key generation
1280 which it of course should've done. The channel keys must be
1281 always re-generated when client leaves (or signoffs) the channel.
1282 The silc_server_remove_from_channels funtion now handles
1283 the channel key re-generation.
1285 * Added `sender' argument to the silc_server_send_notify_on_channels
1286 to not to send the client provided as argument. Affected file
1287 silcd/packet_send.[ch].
1289 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1291 * Implemented OPER and SILCOPER commands into the server and
1294 * Added silc_auth_verify and silc_auth_verify_data to verify
1295 the authentication directly from the authentication payload.
1296 It supports verifying both passphrase and public key based
1297 authentication. Affected file lib/silccore/silcauth.[ch].
1299 * Added `hash' field to the SilcIDListData structure. It is the
1300 hash negotiated in the SKE protocol. Affected file is
1303 * Slight redesigning of the SilcAuthPayload handling routines.
1304 Do not send SilcPKCS but SilcPublicKey as argument.
1306 * Implemented the public key authentication support to the
1307 serverconfig. The public key is loaded from the provided path
1308 and saved as authentication data to void * pointer. Thus,
1309 changed the unsigned char *auth_data to void *auth_data;
1311 * Fixed SHUTDOWN command to send the reply before the server
1312 is shutdown. :) Affected file silcd/command.c.
1314 * Fixed fatal bug in CONNECT command. The hostname was invalid
1315 memory and server crashed. Affected file silcd/command.c.
1317 * Fixed fatal bug in CLOSE command. The server_entry became
1318 invalid but was referenced later in the command. Affected file
1321 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1323 * Fixed fatal bug in failure packet handling. Server ignored
1324 the failure and thus crashed when it came.
1328 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1330 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1331 that the command may be executed only once in (about) 2 seconds.
1332 The old SILC_CF_LAG flag is same but allows command bursts up
1333 to five before limiting.
1335 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1336 server code. Various commands now includes the CF_LAG_STRICT
1337 flag to disallow any kind of miss-use of the command.
1339 * Fixed the silc_buffer_unformat to not to allocate any data
1340 if the length of the data is zero. It used to allocate the
1341 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1343 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1345 * Changed the format of AdminConnection configuration section
1346 in the server. Added username of the admin to the format.
1347 Affected files silcd/serverconfig.[ch].
1349 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1350 to return admin configuration data by host, username and/or
1353 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1355 * Implemented WHOWAS command to the server. Added the functions:
1357 silc_server_command_whowas_parse,
1358 silc_server_command_whowas_send_reply,
1359 silc_server_command_whowas_from_client and
1360 silc_server_command_whowas_from_server
1362 * Added <Client ID> argument to the WHOWAS command reply. Updated
1363 the protocol specs accordingly.
1365 * Implemented WHOWAS command and command_reply to the client
1368 Implemented the WHOWAS printing on the user interface.
1370 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1372 * Added new argument to the WHOWAS command reply, the real name.
1373 It is an optional argument. Updated the protocol specs.
1375 * Added SilcIDCacheDestructor callback that is registered when
1376 the SilcIDCache is allocated. The callback is called when
1377 an cache entry in the ID Cache expires, or is purged from the
1378 cache. Added into lib/silccore/idcache.[ch].
1380 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1381 to destruct the client entries when the cache entry expires.
1382 Other ID Cache's in server and in the client library ignores
1385 * If the ID Cache entry's `expire' field is zero then the entry
1386 never expires. Added boolean `expire' argument to the
1387 silc_idcache_add function in the lib/silccore/idcache.[ch].
1388 If it is TRUE the default expiry value is used.
1390 * Added silc_server_free_client_data_timeout that is registered
1391 when client disconnects. By default for 5 minutes we preserve
1392 the client entry for history - for WHOWAS command.
1394 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1396 * Added support to the server to enforce that commands are not
1397 executed more than once in 2 seconds. If server receives
1398 commands from client more frequently, timeout is registered
1399 to process the commands. Affected file silcd/command.c.
1400 Added new function silc_server_command_process_timeout.
1402 * Changed NICK_NOTIFY handling in client library to check that
1403 if the client's nickname was changed, so there is no need to
1404 resolve anything from the server.
1406 * Removed error printing from the WHOIS and IDENTIFY commands.
1407 If error occurs then it is ignored silently in the client library.
1408 The application, however, may map the received error to
1409 human readable error string. The application currently maps
1410 the NO_SUCH_NICKNAME error to string.
1412 * Made the command status message public to the application. Moved
1413 them from lib/silcclient/command_reply.c to
1414 lib/silcclient/command_reply.h. The application can map the
1415 received command status to the string with the
1416 silc_client_command_status_message function.
1418 * Added check to the server to check that client's ID is same
1419 as the Source ID in the packet the client sent. They must
1422 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1424 * Added dist-bzip hook to the Makefile.am to make bzip2
1425 compressed distributions.
1427 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1429 * Server now enforces the maximum length for the nickname and
1430 the channel as protocol specification dictates. 128 bytes for
1431 nickname and 256 bytes for channel name.
1433 * Moved the WHOIS printing to the application. The client libary
1434 does not print out the WHOIS information anymore, the application
1435 must do it. Renamed silc_client_command_reply_whois_print to
1436 the silc_client_command_reply_whois_save.
1438 The client's idle time is also sent to the application now, and
1439 the idle is shown on screen.
1441 * Added silc_client_command_reply_identify_save to save the
1442 received IDENTIFY entries.
1444 * Do not check for channel private keys in message sending and
1445 reception if the channel does not have the PRIVKEY mode set.
1446 Affected file lib/silclient/client_channel.c.
1448 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1451 just surfaced after chaning the JOIN procedure.
1453 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Added silc_client_get_clients_by_list to get client entries
1456 from Client ID list, that is returned for example by JOIN
1457 and USERS command replies. The application should use this
1458 function for example when JOIN command reply is received to
1459 resolve the clients already on the channel (library does not
1460 do that anymore as USERS command reply is not used in the JOIN
1461 procedure anymore). Affected files lib/silcclient/silcapi.h and
1462 lib/silcclient/idlist.c.
1464 * JOIN command reply and USERS command reply returns now SilcBuffer
1465 pointers instead of unsigned char pointers when returning
1466 the client list and mode list.
1468 * Added <Client ID> argument to the JOIN command reply, mainly
1469 for the server to identify for which client the command was
1470 originally sent. Updated protocol specs accordingly.
1472 * Added SilcDlist private_key pointer to the SilcChannelEntry
1473 in the client to support the channel private keys. Affected
1474 file is lib/silcclient/idlist.h.
1476 * Added SilcChannelPrivateKey argument to the function
1477 silc_client_send_channel_message so that application can choose
1478 to use specific private ke if it wants to. If it is not provided,
1479 the normal channel key is used, unless private keys are set.
1480 In this case the first (key that was added first) is used
1481 as the encryption key.
1483 * Implemented the support for channel private key handling.
1484 Implemented the following functions:
1486 silc_client_add_channel_private_key,
1487 silc_client_del_channel_private_keys,
1488 silc_client_del_channel_private_key,
1489 silc_client_list_channel_private_keys and
1490 silc_client_free_channel_private_keys
1492 Affected file lib/silcclient/client_channel.c.
1494 * Added the support for the private keys in the channel message
1495 sending and encryption and in the message reception and
1496 decryption. Affected funtions are
1497 silc_client_send_channel_message and silc_client_channel_message.
1499 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * Added SKE's key verify callback to the client library's
1502 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1504 * Removed the statement that server (or router) must send USERS
1505 command reply when joining to the channel so that the client
1506 knows who are on the channel. Instead, the client list and
1507 client's mode list is now sent in the JOIN command reply to the
1508 client who joined channel. This is better solution.
1510 * Added function silc_server_get_users_on_channel and function
1511 silc_server_save_users_on_channel to the silcd/server.[ch].
1513 * Removed function silc_server_command_send_users from the
1516 * Do not show topic on the client library anymore. The topic is
1517 sent in the command reply notify to the application and the
1518 application must show the topic now.
1520 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1522 * Added client searching by nickname hash into the IDENTIFY and
1523 WHOIS commands in the server as they were clearly missing from
1524 them. Affected file is silcd/command.c.
1526 * Fixed a bug in private message receiving in the client library.
1527 The remote ID was freed and it wasn't supposed, now it is
1530 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1532 * Minor fix to the channel payload; allocate the data area, as it
1533 needs to be of specific length.
1535 * If the key agreement port is zero then the operating
1536 system will define the bound port. Affected files are
1537 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1539 * Added new function silc_channel_payload_decrypt into the file
1540 lib/silccore/silcchannel.[ch].
1542 * Moved the channel message etc, check from silc_packet_decrypt
1543 to applications. The library calls now a generic
1544 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1545 when the packet is either normal or special. This was done to
1546 allow more wide range of checking that was not allowed when
1547 the code was in library. Now applications can do virtually any
1548 checks to the packet and return to the library the decision how
1549 the packet should be processed. Affected files are
1550 lib/silccore/silcpacket.[ch].
1552 Added silc_server_packet_decrypt_check to the server and
1553 silc_client_packet_decrypt_check to the client library.
1555 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1556 to send with specified source and destination information.
1558 * Channel message delivery between routers was broken after the
1559 channel key distribution was fixed earlier. The channel key
1560 was used be to distributed to other routers as well which is not
1561 allowed by the protocol. Now this is fixed and channel keys
1562 really are cell specific and the channel message delivery between
1563 routers comply with the protocol specification.
1565 * Fixed various commands in server to check also the global list
1566 for the channel entry and not just the local list. The affected
1567 file silcd/command.c.
1569 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1571 * Added assert()s to buffer formatting and unformatting routines
1572 to assert (if --enable-debug) when error occurs. Affected
1573 file: lib/silcutil/silcbuffmt.c.
1575 * Changed to auto-reconnect to check whether the remote host is
1576 router and register the re-connect timeout if it is. It used
1577 to check that whether we are normal server, but router must do
1578 auto-reconnect with another router as well. Affected file
1581 * Removed the [<key len>] option from CMODE command as the cipher
1582 name decides the key length, nowadays. See the defined ciphers
1583 from the protocol specification.
1585 * Added [<hmac>] option to the CMODE command to define the HMAC
1586 for the channel. Added SILC_CMODE_HMAC channel mode.
1588 * Added [<hmac>] option for the JOIN command so that user can
1589 select which HMAC is used to compute the MACs of the channel
1592 * Added Hmac field to the Channel Message Payload. The integrity
1593 of plaintext channel messages are now protected by computing
1594 MAC of the message and attaching the MAC to the payload. The
1595 MAC is encrypted. Now, it is clear that this causes some
1596 overhead to the size of the packet but rationale for this is that
1597 now the receiver can verify whether the channel message decrypted
1598 correctly and also when private keys are set for the channel the
1599 receiver can decrypt the packet with several keys and check from
1600 the MAC which key decrypted the message correctly.
1602 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1603 lib/silccrypt/silccipher.[ch].
1605 * Added silc_hash_len to return the digest length into the
1606 lib/silcrypt/silchash.[ch].
1608 * Rewrote parts of Silc Channel Payload interface in the
1609 lib/silccore/silcchannel.[ch]. The encode function now also
1610 encrypts the packet and parse function decrypts it.
1612 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1614 * Fixed a minor formatting bug in the SKE's key material processing.
1615 It actually might have processed the keys wrong way resulting
1618 * Redefined the mandatory HMAC algorithms and added new algorithms.
1619 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1620 and hmac-md5 truncated to 96 bits. The mandatory is now
1621 hmac-sha1-96. Rest are optional (including the one that used
1622 to be mandatory). Rationale for this is that the truncated HMAC
1623 length is sufficient from security point of view and can actually
1624 make the attack against the HMAC harder. Also, the truncated
1625 HMAC causes less overhead to the packets. See the RFC2104 for
1628 * Added new [hmac] configuration section. The SKE used to use
1629 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1630 is of course wrong. The official names that must be proposed in
1631 the SKE are the ones defined in the protocol specification
1632 (hmac-sha1-96 for example). The user can configure any hmac
1633 using any hash function configured in the [hash] section. At
1634 least, the mandatory must be configured.
1636 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1638 * Added HMAC list to the SKE proposal list. It has now both
1639 hash algorithm list and HMAC list. This makes the protocol
1640 incompatible with previous versions. The SKE now seems to work
1641 the way it is supposed to work, for the first time actually.
1643 * Defined plain Hash algorithms to the protocol specification.
1646 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1648 * Implemented support for key agreement packets into the server.
1649 Added functions silc_server_key_agreement and
1650 silc_server_send_key_agreement. Other than these functions,
1651 server has nothing to do with this packet.
1653 * Added support for private message key packets into the server.
1654 Added functions silc_server_private_message_key and
1655 silc_server_send_private_message_key.
1659 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1660 called in the protocol's final callback instead in the END
1661 protocol state. This makes a little more sense and in the same
1662 time in client we can use the same protocol routines for normal
1663 key exchange and to key agreement packet handling as well.
1665 * Added to both client's and server's KE protocol context the
1666 SilcSKEKeyMaterial pointer to save the key material. We will
1667 bring the key material to the protocol's final callback by doing
1668 this. The final callback must free the key material.
1670 * Added SKE's packet_send callback into client's KE protocol
1671 context so that the caller can choose what packet sending function
1672 is used. This way we can use different packet sending when
1673 doing normal SKE when doing key agreement packet handling (in
1674 the key agreement packet handling we do not want to encrypt
1677 * Implemented the responder side of the key agreement routines
1678 in the client. The client can now bind to specified port and
1679 accept incoming key negotiation. The key material is passed
1680 to the application after the protocol is over.
1682 * Implemented the processing of incoming Key Agreement packet
1683 in the client. Added function silc_client_key_agreement to
1686 * Implemented the intiator side of the key agreement routines
1687 in the client. The client can now initiate key agreement with
1688 another remote client. The key material is passed to the
1689 application after the protocol is over.
1691 * Created client_keyagr.c to include all the key agreement
1694 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1695 SILC_TASK_CALLBACK except that it is not static.
1697 * Created client_notify.c and moved the Notify packet handling
1698 from the client.[ch] into that file.
1700 * Created client_prvmsg.c and moved all private message and
1701 private message key routines from the client.[ch] into that file.
1703 * Create client_channel.c and moved all channel message and
1704 channel private key routines from the client.[ch] into that file.
1706 * Changed silc_client_get_client_by_id_resolve to resolve with
1707 WHOIS command instead of IDENTIFY command, in the file
1708 lib/silclient/idlist.c.
1710 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1712 * Implemented the SKE's responder side to the Client library.
1714 * When FAILURE is received to the protocol do not trust it
1715 blindly. Register a timeout to wait whether the remote closes
1716 the connection as it should do it, only after that process the
1717 actual failure. This was changed to both client and server.
1719 * Added client_internal.h to include some of the structures
1720 there instead of client.h in lib/silcclient/.
1722 * Added function silc_task_unregister_by_callback to unregister
1723 timeouts by the callback function.
1725 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1727 * Some "Incomplete WHOIS info" errors has been appearing on the
1728 log files. Took away the entry->userinfo check from WHOIS
1729 reply sending. The entry->userinfo is now " " if client did not
1730 provide one. I thought this was fixed earlier but something
1731 is wrong still. Let's see if the error still appears.
1733 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1735 * Fixed a minor bug in the login when the channel key is
1736 re-generated in the server. It used to generate the key in
1737 wrong order and thus caused problems in the channel traffic.
1739 * Fixed a minor bug in channel key distsribution after
1740 KICK command. The key was not sent to the router even though
1743 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1745 * Added silc_ske_process_key_material_data as generic routine
1746 to process any key material as the SILC protocol dictates. The
1747 function is used by the actual SKE library but can be used by
1748 applications as well. This relates to the private message keys
1749 and the channel private keys since they must be processed the
1750 same way the normal SILC session keys. The protocol dictates
1751 this. Affected files: lib/silcske/silcske.[ch].
1753 Added also silc_ske_free_key_material to free the
1754 SilcSKEKeyMaterial structure.
1756 * Defined silc_cipher_set_key function to set the key for
1757 cipher without using the object's method function. The affected
1758 files: lib/silccrypt/silccipher.[ch].
1760 * Implemented silc silc_client_add_private_message_key,
1761 silc_client_add_private_message_key_ske,
1762 silc_client_del_private_message_key,
1763 silc_client_list_private_message_keys and
1764 silc_client_free_private_message_keys functions in the
1767 Added functions silc_client_send_private_message_key to send
1768 the Private Message Key payload and silc_client_private_message_key
1769 to handle incoming Private Message Key payload.
1771 * Added Cipher field to the Private Message Key payload to set
1772 the cipher to be used. If ignored, the default cipher defined
1773 in the SILC protocol (aes-256-cbc) is used.
1775 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1777 * Removed lib/silcclient/ops.h file.
1779 Redefined parts of the SILC Client Library API. Created new
1780 file silcapi.h that deprecates the ops.h file and defines the
1781 published Client Library API. Defined also private message key
1782 API and channel private key API into the file.
1784 This is the file that the application must include from the
1785 SILC Client Library. Other files need not be included by
1786 the application anymore.
1788 * Added new key_agreement client operation callback and also
1789 defined the Key Agreement library API for the application.
1791 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1794 is used by clients to request key negotiation between another
1795 client in the SILC network. If the negotiation is started it
1796 is performed using the SKE protocol. The result of the
1797 negotiation, the secret key material, can be used for example
1798 as private message key.
1800 Implemented the Key Agreement payload into the files
1801 lib/silccore/silauth.[ch].
1803 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Redefined ciphers for the SILC protocol. Added some new ciphers
1806 and defined the key lengths for the algorithms. Changed the
1807 code accordingly. The default key length is now 256 bits.
1809 * Fixed SKE key distribution function silc_ske_process_key_material
1810 when the key length is more than 128 bits. The default key
1811 length in SILC is now 256 bits.
1813 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1814 to indicate unsupported algorithm.
1816 * Renamed rijndael.c to aes.c and all functions as well.
1818 * Fixed a long standing channel key setting bug in client library.
1819 Weird that it has never surfaced before.
1821 * Fixed bug in channel deletion. If the entire channel is removed
1822 then it must also delete the references of the channel entry
1823 from the client's channel list as the client's channel entry and
1824 the channel's client entry share same memory.
1826 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1828 * Implemented CONNECT and SHUTDOWN commands in the client.
1830 * Implemented CLOSE command to the client.
1832 * Added the function silc_idlist_find_server_by_name into the
1833 files silcd/idlist.[ch].
1835 Added the function silc_idlist_find_server_by_conn into the
1836 files silcd/idlist.[ch].
1838 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1840 * DIE command was renamed to SHUTDOWN. Updated the both code
1843 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1844 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1846 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1849 * Added function silc_server_create_connection function to create
1850 connection to remote router. My server implementation actually
1851 does not allow router to connect to normal server (it expects
1852 that normal server always initiates the connection to the router)
1853 so the CONNECT command is only good for connecting to another
1856 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1858 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1859 or some other client was kicked from the channel.
1861 Implemented the handling of the notify type to both client
1864 Implemented silc_server_send_notify_kicked to send the KICKED
1865 notify. It is used to send it to the server's primary router.
1867 * Implemented the KICK command into server and client.
1869 * Added `query' argument to the silc_idlist_get_client function
1870 to indicate whether to query the client from server or not if
1873 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1874 to indicate that the client is not channel founder.
1878 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * Removed the rng context from SilcPacketContext structure and
1881 changed that the packet routine uses the Global RNG API.
1883 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1885 * Added support for quit message that client can "leave" on the
1886 channel when it quits the SILC. It is ditributed inside the
1887 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1889 Added silc_server_free_client_data that will take the
1890 signoff message as argument.
1892 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1894 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * Updated parts of the protocol specification to keep it up
1899 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1901 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1902 payloads in one packet.
1904 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1905 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1906 use now the new List flag.
1908 * Also deprecated the following packet types: REPLACE_ID,
1909 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1911 * Added list support for Notify packet in server.
1913 * Added silc_server_send_notify_channel_change to send the
1914 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1915 the silc_server_send_replace_id.
1917 * Added silc_server_send_notify_nick_change to send the
1918 NICK_CHANGE notify type. Deprecates the function
1919 silc_server_send_replace_id.
1921 * Added silc_server_send_notify_join to send the JOIN notify type.
1922 Deprecates the function silc_server_send_new_channel_user.
1924 * Added silc_server_send_notify_leave to send LEAVE notify type.
1925 Deprecates the function silc_server_send_remove_channel_user.
1927 * Added silc_server_send_notify_cmode and
1928 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1929 types. Deprecates the silc_server_send_set_mode function.
1931 * Added SERVER_SIGNOFF notify type to indicate that server has
1932 quit. This means that all clients on the channel from that
1933 server will drop. This can be also used when netsplit happens.
1935 Deprecated REMOVE_ID packet type since it is not needed anymore
1938 Added silc_server_send_notify_server_signoff to send the
1939 SERVER_SIGNOFF notify type. Deprecates the function
1940 silc_server_send_remove_id.
1942 Added also silc_server_send_notify_signoff to send the
1943 SIGNOFF notify type.
1945 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1946 SILC protocol from this day on. Changed the protocol
1947 specification as well.
1949 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1950 notify type. It is used between routers to notify about
1951 topic changes on a channel.
1953 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1956 * Partly updated the protocol specification to comply with the
1957 changes now made. It is still though a bit outdated.
1959 * The JOIN notify type now takes one extra argument <Channel ID>.
1960 The packet used to be destined to the channel but now the
1961 JOIN type may be sent as list thus it is impossible to
1962 destine it to any specific channel. By adding this argument
1963 it is again possible.
1965 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1967 * Added CREDITS file. The CHANGES and CREDITS file will appear
1968 in the distribution as well.
1970 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1972 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1973 types in the server's silcd/packet_receive.c.
1975 * Implemented CMODE and CUMODE to work in router environment.
1977 * Fixed minor encoding and decoding buglet from the
1978 lib/silccore/silcmode.c.
1980 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1983 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1985 * Changed all SilcConfigServer* and silc_config_server* to
1986 SilcServerConfig* and silc_server_config*, respectively.
1989 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1991 * Associated the ID (client or server ID) to the Authentication
1992 Payload to avoid any possibility of forging. Updated the
1993 protocol specification and the code accordingly.
1995 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * The RSA key length is now save to the RsaKey context in the
1998 key generation process in lib/silccrypt/rsa.c. The key length
1999 is now used to figure out the maximum size of the block allowed
2000 to be encrypted/signed.
2002 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2003 is equivalent to the silc_mp_mp2bin but does not allocate any
2006 * Changed silc_mp_mp2bin API to take length argument. If it is
2007 non-zero then the buffer is allocated that large. If zero, then
2008 the size is approximated using silc_mp_sizeinbase, which however
2011 * Created Global RNG API which is global RNG that application can
2012 initialize. After initializing, any routine anywhere in the
2013 code (including library) can use RNG without allocating a new
2014 RNG object. This was done to allow this sort of use of the
2015 RNG in code that has no chance to allocate RNG object. All
2016 applications currently allocate this and many routines in the
2017 library use this. Affected file lib/silccrypt/silcrng.[ch].
2019 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2020 it to use the Global RNG API.
2022 * Defined Authentication Payload into protocol specification that
2023 is used during SILC session to authenticate entities. It is
2024 used for example by client to authenticate itself to the server
2025 to obtain server operator privileges.
2027 Implemented this payload into the lib/silccore/silcauth.[ch].
2028 Implemented also routines for public key based authentication
2029 as the new protocol specification dictates.
2031 Moved definitions of different authentication methods from
2032 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2034 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2035 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2036 silc_pkcs_verify_with_hash functions into the file
2037 lib/silccrypt/silcpkcs.[ch].
2039 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * The client entry's userinfo pointer must be always valid.
2042 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2043 will fail since it requires the userinfo. Now, the userinfo
2044 is allocated as "" if actual userinfo does not exist. Actually,
2045 it must exist and it is totally Ok to drop client connections
2046 that does not announce the userinfo. However, we will make
2047 this workaround for now.
2049 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2050 to return the remote port by socket.
2052 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2054 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2055 SILC_SERVER_PENDING_EXEC and added an new macro
2056 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2057 data or when error occurs while processing the pending command.
2059 Added new argument `destructor' into silc_server_command_pending
2060 and to the SilcServerCommandPending object. This destructor is
2061 now called after calling the pending callback or if error occurs
2062 immediately. If error occurs the actual pending callback won't
2063 be called at all - only the destructor. The destructor may be
2064 NULL if destructor is not needed.
2066 All this applies for client library code as well. Similar
2067 changes were made there as well for the pending commands.
2069 In the client, the application must now allocate the
2070 SilcClientCommandContext with the silc_client_command_alloc
2073 * Added reference counter to the SilcServerCommandContext. Added
2074 function silc_server_command_alloc and silc_server_command_dup
2077 Same type of functions added to the client library for the same
2080 * Removed the cmd_ident from IDListData away since it is now
2081 global for all connections. It is the command identifier used
2082 in command sending and with pending commands. The affected file
2085 * Added reference counter to the SilcSocketConnection objecet to
2086 indicate the usage count of the object. The object won't be
2087 freed untill the reference counter hits zero. Currently only
2088 server uses this, and client ignores it. The client must be
2089 set to use this too later. The affected files are
2090 lib/silccore/silcsockconn.[ch]. Added also the function
2091 silc_socket_dup to increase the reference counter.
2093 This was mainly added because it is possible that the socket
2094 is removed underneath of pending command or other async
2095 operation. Now it won't be free'd and proper DISCONNECTING
2096 flags, etc. can be set to avoid sending data to connection that
2097 is not valid anymore.
2099 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2100 the connection. After that it sets SILC_SET_DISCONNECTED.
2101 It is, however, possible that the socket data is not still freed.
2102 The silc_server_packet_process now checks that data is not
2103 read or written to connection that is DISCONNECTED. The socket
2104 get's freed when the reference counter hits zero.
2106 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Changed the client operation API: channel_message operation's
2109 `sender' is now the client entry of the sender, not the nickname
2110 and the `channel' is the channel entry, not the channel name.
2112 In the private_message operation the `sender' is now also the
2113 client entry of the sender not the nickname.
2115 Affected file is lib/silcclient/ops.h and all applications
2116 using the client operations.
2118 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2120 * Moved the calling of ops->connect() from connect_to_server_final
2121 into receive_new_id functin since that is the point when the
2122 client is actually allowed to send traffic to network. The
2123 affected file is lib/silcclient/client.c.
2125 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2128 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2129 (if needs broadcasting) instead of broadcasting the packets one
2130 by one which would make a burst in the network traffic.
2132 * Added `broadcast' argument to the functions in silcd/server.[ch]
2133 silc_server_create_new_channel[_with_id] to indicate whether
2134 to send New Channel packet to primary router.
2136 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2138 * Added new function into the silcd/server.[ch] files:
2139 silc_server_create_new_channel_with_id to create new channel with
2140 already existing Channel ID.
2142 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2143 lib/silccore/silcpacket.h. This packet is used t send list of
2144 Set Mode payloads inside one packet. Server uses this to set
2145 the modes for the channels and clients on those channels, that it
2146 announced to the router when it connected to it. The protocol
2147 specification has been updated accordingly.
2149 * The silc_server_new_channel did not handle the packet coming
2150 from normal server as it normally does not send that. However,
2151 when it announces its channels it does send it. Implemented
2152 the support for that.
2154 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2155 into the file lib/silccore/id.h.
2157 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2159 * Fixed memory leaks in the functions silc_idlist_del_client,
2160 silc_idlist_del_channel and silc_idlist_del_server in the file
2161 silcd/idlist.c. All of those leaked like a sieve.
2163 * Fixed some small memory leaks in the client's function
2164 silc_client_notify_by_server.
2166 * Added functions into silcd/server.c: silc_server_announce_clients,
2167 silc_server_announce_channels and silc_server_announce_server.
2168 These functions are used by normal and router server to announce
2169 to its primary router about clients, channels and servers (when
2170 router) that we own. This is done after we've connected to the
2173 These functions effectively implements the following packet types:
2174 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2175 and SILC_PACKET_NEW_ID_LIST.
2177 * Added new functions into the silcd/packet_receive.[ch]:
2178 silc_server_new_id_list, silc_server_new_channel_list and
2179 silc_server_new_channel_user_list to handle the incoming
2180 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2182 * Added support of changing Channel ID in the function
2183 silc_server_replace_id. If the server that announces a channel
2184 to the router already exists in the router (with same name but
2185 with different Channel ID), router is responsible to send
2186 Replace ID packet to the server and force the server to change
2187 the Channel ID to the one router has.
2189 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2190 client that the Channel ID has been changed by the router. The
2191 normal server sends this to the client. Client must start using
2192 the new Channel ID as the channel's ID.
2194 Implemented handling of this new type into lib/silcclient/client.c
2195 into the function silc_client_notify_by_server.
2197 * Added new function silc_idlist_replace_channel_id into the files
2198 silcd/idlist.[ch] to replace the Channel ID.
2200 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Call silc_server_command_identify_check always when processing
2203 the IDENTIFY command in silcd/command.c
2205 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2207 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2208 send keepalive packets. The packet can be sent by clients,
2209 servers and routers.
2211 Added function silc_socket_set_heartbeat into the file
2212 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2213 If not set, the heartbeat is not performed. The actual
2214 heartbeat is implemented in the low level socket connection
2215 library. However, application is responsible of actually
2218 Added silc_server_send_heartbeat to send the actual heartbeat
2219 packet into silcd/packet_send.[ch]. Server now performs
2220 keepalive with all connections.
2222 * Added silc_task_get_first function into lib/silcutil/silctask.c
2223 to return the timeout task with shortest timeout. There was a bug
2224 in task unregistration that caused problems. TODO has been
2225 updated to include that task system must be rewritten.
2227 * The client library will now resolve the client information when
2228 receiving JOIN notify from server for client that we know but
2229 have incomplete information.
2231 * Rewrote parts of silc_server_remove_from_channels and
2232 silc_server_remove_from_one_channel as they did not remove the
2233 channel in some circumstances even though they should've.
2235 * Encryption problem encountered in server:
2237 The LEAVE command used to send the Channel Key packet to the
2238 router immediately after generating it. However, the code
2239 had earlier sent Remove Channel user packet but not immediately,
2240 ie. it was put to queue. The order of packets in the router
2241 was that Channel Key packet was first and Remove Channel User
2242 packet was second, even though they were encrypted in the
2243 reverse order. For this reason, MAC check failed. Now, this
2244 is fixed by not sending the Channel Key packet immediately but
2245 putting it to queue. However, this is more fundamental problem:
2246 packets that are in queue should actually not be encrypted
2247 because packets that are sent immediately gets encrypted
2248 actually with wrong IV (and thus MAC check fails). So, packets
2249 that are in queue should be encrypted when they are sent to
2250 the wire and not when they put to the queue.
2252 However, the problem is that the current system has not been
2253 designed to work that way. Instead, the packet is encrypted
2254 as soon as possible and left to the queue. The queue is then
2255 just purged into wire. There won't be any fixes for this
2256 any time soon. So, the current semantic for packet sending
2259 o If you send packet to remote host and do not force the send
2260 (the packet will be in queue) then all subsequent packets to the
2261 same remote host must also be put to the queue. Only after the
2262 queue has been purged is it safe again to force the packet
2265 o If you send all packets immediately then it safe to send
2266 any of subsequent packets through the queue, however, after
2267 the first packet is put to queue then any subsequent packets
2268 must also be put to the queue.
2270 Follow these rules and everything works fine.
2272 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2274 * Added new function silc_server_remove_clients_by_server to
2275 remove all client entries from ID list when the server connection
2276 is lost. In this case it is also important to invalidate all
2277 client entires as they hold the invalid server entry. This
2278 fixes fatal bug when server has lost connection and will reconnect
2281 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Made some sanity checks to silc_server_daemonise like to check
2284 whether the requested user and group actually exists.
2286 * Added sanity check to SKE's silc_ske_responder_finish to check
2287 that the public and private key actually is valid.
2289 * Invalidate the client's nickname when receiving Replace ID
2290 packet and the Client ID is being replaced. This means that the
2291 server will query the nickname if someone needs it (client)
2294 * Sort the ID Cache in client library when the ID Cache data
2295 has changed (needs sorting).
2297 * Do not allow for SILC client to create several connections to
2298 several servers. The client does not support windows right now
2299 and generating multiple connections causes weird behaviour.
2301 Irssi-silc client does support windows and can handle several
2302 connections without problems, see: www.irssi.org and SILC plugin.
2304 * Fixed some places where client was added to the IDList. The
2305 rule of thumb is following (in order to get everything right):
2306 If the client is directly connected local client then the
2307 `connection' argument must be set and `router' argument must be
2308 NULL to silc_idlist_add_client function. If the client is not
2309 directly connected client then the `router' argument must
2310 bet set and the `connection' argument must be NULL to the
2311 silc_idlist_add_client function.
2313 * The funtion silc_server_packet_send_local_channel actually did
2314 not check whether the client was locally connected or not. It
2315 does that now. Fixed a bug related to LEAVE command.
2317 * Fixed Remove Channel User payload parsing bug in server's
2318 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2320 * The server's silc_server_save_channel_key now checks also the
2321 global ID list for the channel as it might not be in the local
2322 list. Fixed a bug related to LEAVE command.
2324 * Is this the end of the [<unknown>] buglet that has been lurking
2325 around for a long time? A little for loop fix in server's
2326 silc_server_command_whois_parse that is used by both IDENTIFY
2327 and WHOIS command. At least, this was a clear bug and a cause
2328 of one type of [<unknown>] buglet.
2330 * WHOIS and IDENTIFY commands call the function
2331 silc_server_command_[whois/identify]_check function even if
2332 we are not router server.
2334 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2336 * Added --with-gmp configuration option. If set the GMP
2337 is always compiled in the SILC source tree. If not set then
2338 it is checked whether the system has the GMP3 installed. If
2339 it has then the GMP won't be compiled (the system's headers
2340 and library is used), if it doesn't have it then the GMP is
2341 compiled in the SILC source tree.
2343 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Changed RSA private exponent generation to what PKCS #1
2346 suggests. We try to find the smallest possible d by doing
2347 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2348 not security fix but optimization.
2350 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Added new config entry [Identity] to fork the server and run
2353 it as specific user and group. A patch from Bostik.
2355 * Imported Dotconf configuration library into lib/dotconf.
2356 This will be used to create the SILC configuration files later.
2357 It will appear in the distsribution after this commit.
2359 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2361 * A big code auditing weekend happening. Auditing code for
2362 obvious mistakes, bugs and errors. Also, removing any code
2365 Removed files for being obsolete:
2367 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2368 inline in the file lib/silcutil/silcbuffer.h)
2370 o lib/silcutil/silcbufutil.c (the header has inline versions)
2372 Changed code to fix possible error conditions:
2374 o The buffer formatting routines now check that the destination
2375 buffer really has enough space to add the data. This applies for
2376 both buffer formatting and unformatting
2377 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2378 unformatting was changed to accomodate following rules:
2379 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2380 sent to the function while XXX_*STRING will not allocate or copy
2381 the data into the buffer. Instead it sets the pointer from the
2382 buffer into the pointer sent as argument (XXX_*STRING used to
2383 require that the pointer must be allocated already). This change
2384 makes this whole thing a bit more consistent and more optimized
2385 (note that the data returned in the unformatting with XXX_*STRING
2386 must not be freed now). The routines return now -1 on error.
2388 o Tried to find all code that use buffer_format and buffer_unformat
2389 and added return value checking to prevent formatting and
2390 especially unformatting errors and possible subsequent fatal
2393 o Changed ske->x and ske->KEY to mallocated pointers in
2394 lib/silcske/silcske.h. Fixed possible data and memory leak.
2396 o Added return value checking to all *_parse* functions. Fixed
2397 many memory leaks as well.
2399 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2400 so that buffer overflows would not happen. All code now also
2401 checks the return value as it can fail.
2403 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2405 * Added reconnection support to server if the normal server looses
2406 its connection to the router (for example if router is rebooted).
2407 The server performs normal reconnection strategy implemented
2408 to the server. Affected file silcd/server.c.
2410 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2412 * Added new packet type SILC_PACKET_SET_MODE that is used to
2413 distribute the information about changed modes (for clients,
2414 channels and clients channel modes) to all routers in the
2415 network. Updated the protocol specification accordingly.
2417 Added functions into silcd/packet_send.c and
2418 silcd/packet_receive.c: silc_server_send_set_mode,
2419 silc_server_set_mode.
2421 Added new files silcmode.[ch] into lib/silccore that implements
2422 the encoding and decoding of Set Mode Payload. Added new type
2423 SilcSetModePayload. Moved the definitions of different modes
2424 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2426 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2428 * Oops, a little mistake in server's connection authentication
2429 protocol. The protocol is not ended with FAILURE but with
2430 SUCCESS if the authentication is Ok. :) Affected file is
2433 * Implemented NICK_CHANGE notify handling in server in the file
2434 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2435 the local clients on the channel. After the changing nickname
2436 in router environment snhould work and the [<unknown>] nickname
2437 should appear no more.
2439 The silc_server_replace_id function that receives the Replace ID
2440 payload now sends the NICK_CHANGE notify type also in the file
2441 silcd/packet_receive.c
2443 * Changed WHOIS and IDENTIFY command to support the maximum amount
2444 of arguments defined in protocol specs (3328 arguments). This
2445 fixed a bug that caused problems when there were more than three
2448 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2450 * Added extra parameter, command identifier, to the
2451 silc_client_send_command so that explicit command identifier
2454 Changed that ID list routines uses specific command identifier
2455 when sending WHOIS/IDENTIFY requests to the server so that they
2456 can be identified when the reply comes back.
2458 Affected files lib/silcclient/command.[ch],
2459 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2461 * Added `sender' argument to silc_server_packet_send_to_channel
2462 to indicaet the sender who originally sent the packet to us
2463 that we are now re-sending. Ignored if NULL. Affected file
2464 silcd/packet_send.[ch].
2466 * Added some server statistics support in silcd/server_internal.h
2467 SilcServerStatistics structure and around the server code. Also
2468 send some nice statistics information when client is connecting
2471 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Fixed channel ID decoding in server's JOIN command reply in
2474 silcd/command_reply.c
2476 * Fixed braodcasting of replace ID payload to not to send it if
2477 we are standalone server in silcd/packet_receive.c.
2479 * Fixed all channel message sending routines to not to send
2480 packets to clients that has router set, since they are routed
2481 separately in the same function earlier. Affects file
2482 silcd/packet_send.c and all channel packet sending functions.
2484 * In USERS reply, res_argv[i] are not allocated, the table
2485 is allocated. Thus changed that free the table, not its
2488 * In server's whois_check and identify_check if the client is
2489 locally connected do not send any WHOIS commands - they are not
2492 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Fixed some minor bugs in client when sending WHOIS command. The
2495 arguments was in wrong order.
2497 * Removed statis function add_to_channel from server in
2498 silcd/command.c that was previously used with the joining but
2501 * Tested USERS command in router environment successfully with two
2502 routers, two servers and two clients.
2504 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Reorganized the USERS command and command reply in client library
2507 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2508 When the command is given by user we register a pending command
2509 callback that will reprocess the command after the reply has been
2510 received from the server. When reprocessing the packet we then
2511 display the information. Thus, the USERS information is displayed
2512 now in the command callback instead of in the command reply
2513 callback. The processing of the command is same as previously
2514 when server has sent the command reply in the JOINing process.
2516 * Added to USERS command in silcd/command_reply.c to join the client,
2517 we didn't use to know about, to the channel after we've created
2518 a client entry for it. Also, for clienet we did know already still
2519 check whether it is on the channel or not and add it if not.
2521 * Removed silc_server_command_join_notify as the function and its
2524 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * Changed the client's pending command handling to the same as the
2527 server's pending command handling. It is also now possible to
2528 execute command reply functions from other command reply
2529 function as the function callbacks for commands and command
2530 replies are one and same. The pending commands are not static
2531 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2532 in client connection context. Thus, pending commands are server
2533 connection specific as it is convenient.
2535 Changed the function silc_client_command_pending and
2536 silc_client_command_pending_del and added new function
2537 silc_client_command_pending_check. Removed the
2538 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2541 * Added cmd_ident, current command identifier, to the client
2542 connection context in lib/silcclient/client.h to keep track on
2543 command identifiers used in command sending. Client's command reply
2544 function handling now supports the mandatory command identifiers.
2546 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2547 funtions in client to fully support pending command callbacks.
2549 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2550 as one of the arguments to the application in the command reply
2553 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2554 before first releasing SILC but came back. Now it is removed again
2555 and should come back nomore. The FORWARDED flag was used only
2556 by the JOINing procedure by forwarding the command packet to router.
2557 Now, the JOINing procedure has been changed to more generic (due
2558 to various router environment issues) and FORWARDED is not needed
2559 anymore for anything. The protocol specification is yet to be
2562 Now, removed silc_server_packet_forward from server and the flag
2563 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2565 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2567 * Renamed NAMES command to USERS command. The NAMES was named that
2568 due to historical reasons. Now it is renamed. Also, rewrote
2569 parts of the USERS command. The nickname list is not sent anymore
2570 by the server. Only Client ID and mode lists are sent in the USERS
2571 command. Changed this also to the protocol specification.
2573 The client now resolves the names and stuff after it receives
2574 the USERS list from the server when joining to the channel.
2576 * WHOIS and IDENTIFY commands has been changed to support multiple
2577 Client ID's per command. One can now search for multiple users
2578 in the network by sending only one WHOIS or IDENTIFY command.
2579 Changed the code and the protocol specifications.
2581 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2582 uses silc_server_command_whois_parse to parse the request. */
2584 * If normal server, do not parse the WHOIS and IDENTIFY requests
2585 before sending it to the router. Saves some time.
2587 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Fixed JOIN command on client library. Wrong number of arguments
2590 used to crash the client.
2592 * Added silc_server_channel_has_global function to check whether
2593 channel has global users or not.
2595 * Added silc_server_channel_has_local function to check whether channel
2596 has locally connected clients on the channel.
2598 * The silc_server_remove_from_one_channel now checks whether the
2599 channel has global users or not after given client was removed from
2600 the channel. It also checks whether the channel has local clients
2601 on the channel anymore. If it does not have then the channel entry
2602 is removed as it is not needed anymore.
2604 * The silc_server_notify now checks on JOIN notify whether the joining
2605 client is one of locally connected or global. If it is global then
2606 the channel has now global users on the channel and that is marked
2607 to the channel entry. Also, it now saves the global client to
2608 global list who is joining and JOINs it to the channel. This is
2609 for normal server, that is.
2611 Changed silc_server_send_notify_on_channel,
2612 silc_server_packet_relay_to_channel and
2613 silc_server_packet_send_to_channel check if we are normal server
2614 and client has router set (ie. global client) do not send the
2615 message to that client, as it is already routed to our router.
2617 * Implemented LEAVE notify type handling in silc_server_notify
2620 * Tested LEAVE command in router environment successfully. Tested
2621 with two routers, two servers and two clients.
2625 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2627 * Implemented SIGNOFF notify type handling in silc_server_notify
2630 * silc_server_remove_id now removes the client entry from all channels
2631 it has joined and thusly sends SIGNOFF notify type.
2633 * Rewrote the NAMES list generation in server by removing two excess
2634 loops. The lists are created now inside one loop.
2636 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * silc_server_remove_channel_user checks now also global list
2639 for channel and client.
2641 * silc_server_new_channel_user checks now both local and global
2642 list for channel and client. Fixed a bug in client id decoding.
2643 Used to decode wrong buffer.
2645 * silc_server_channel_message checks now both local and global
2646 list for channel entry.
2648 * Tested channel joining (hence JOIN) in router environment
2649 successfully. Tested with two routers, two servers and two
2652 * Tested channel message sending in router environment successfully.
2654 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2656 * Added silc_server_save_channel_key into server.[ch] to save the
2657 received channel key in Channel Key payload processing. It is
2658 also used in JOIN command reply handling.
2660 Equivalent function silc_client_save_channel_key added into
2661 client.[ch] into client library.
2663 * Changed JOIN command reply to send information whether the channel
2664 was created or not (is existing already) and the channel key
2665 payload. Changed protocol specs accordingly.
2667 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2668 the request was sent by ID and not by nickname. Crashed on
2671 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2673 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2674 now correctly save the received data.
2676 * silc_server_free_sock_user_data now notifies routers in the
2677 network about entities leaving the network.
2679 At the same time implemented functions silc_server_remove_id
2680 and silc_server_send_remove_id to receive and send REMOVE_ID
2681 packets. The packet is used to notify routers in the network
2682 about leaving entities. The ID removed will become invalid in
2685 * Added function silc_idlist_del_server into server. Removes and
2686 free's server entry from ID list.
2688 * silc_server_private_message function now checks, if we are router,
2689 that the destination ID really is valid ID, naturally.
2691 * In router when NEW_ID packet is received (for new client) the
2692 hash of the Client ID is saved in the ID Cache but the
2693 client->nickname is set to NULL, instead of putting the hash
2696 IDENTIFY command now also checks that client->nickname must be
2697 valid. If it is not if will request the data from the server who
2698 owns the client. Added new function
2699 silc_server_command_identify_check.
2701 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2702 to set the command to already allocated Command Payload.
2704 * Tested private message sending in router environment with two
2705 routers, two servers and two clients. Fixed minor bugs and now
2708 * Fixed segfault from client's NAMES command. Used to crash if
2711 * Forwarded packets must not be routed even if it is not destined
2712 to the receiver. Changed server code comply with this.
2714 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2716 * Added `require_reverse_mapping' boolean value to ServerParams
2717 structure. If TRUE (not default) the server will require that
2718 the connecting host has fully qualified domain name.
2720 If the reverse mapping is not required and hostname could not be
2721 found the IP address is used as hostname.
2723 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2725 * Implemented version string checking to both client and server.
2726 The check is incomplete currently due to the abnormal version
2727 strings used in development version of SILC.
2729 * Changed all command functions in server to use the new
2732 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2734 * Changed char *data to unsigned char *data in ID Cache system to
2735 support binary data as ID Cache data. Changed code to support
2736 binary data in lib/silccore/idcache.c.
2738 * Renamed silc_server_packet_relay_command_reply to
2739 silc_server_command_reply as it is normal packet receiving
2740 function. Rewrote the function to accept command replys for
2741 servers and not only for clients.
2743 * Mark remote router always as registered server if we are connecting
2744 to it. Otherwise, commands sent by the router to us are ignored.
2746 * All ID List find routines now returns the ID Cache Entry pointer
2747 as well if requested.
2749 * WHOIS command works now in router environment, tested with two
2750 routers, two servers and two clients.
2752 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2753 in router environment (as it is almost equivalent to WHOIS) but
2754 hasn't been tested thoroughly. Added new functions:
2756 silc_server_command_identify_parse
2757 silc_server_command_identify_send_reply
2758 silc_server_command_identify_from_client
2759 silc_server_command_identify_from_server
2761 * Disabled route cache adding because adding two different ID's with
2762 same IP replaces the old cache entry thus giving wrong route.
2763 The entry->router->connection is always the fastest route anyway
2764 so route cache may not be needed. Of course, new routes maybe
2765 established after receiving the ID when the entry->router->connection
2766 might not be anymore the most optimal.
2768 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * Add route cache for received ID for fast routing.
2772 * Added silc_server_packet_route to route received packet on router
2773 that is not destined to us.
2775 * Renamed silc_server_get_route to silc_server_route_get.
2777 * Added id_string and id_string_len fields into SilcServer to
2778 include encoded ServerID for fast comparing without excess
2779 encoding of the ID's.
2781 * Cleaned up WHOIS command on server side. Added following static
2784 silc_server_command_whois_parse
2785 silc_server_command_whois_check
2786 silc_server_command_whois_send_reply
2787 silc_server_command_whois_from_client
2788 silc_server_command_whois_from_server
2790 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2791 arguments in command replies. All command functions should be
2792 updated to use this macro.
2794 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2796 * Minor typo fixes on command reply handling on server.
2798 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Added silc_server_command_add_to_channel internal routine to add
2801 the client to the channel after router has created the channel and
2802 sent command reply to the server.
2804 * Added generic silc_server_send_command to send any command from
2807 * Use static buffer with ID rendering instead of duplicating data.
2809 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Fixed a channel user mode bug when joining to a channel server gave
2812 everybody channel founder rights, oops.
2814 * We mark ourselves as the router of the incoming server connection
2815 if we are router ourselves. This way we can check in some packet
2816 sending functions whether it is locally connected server. For
2817 incoming router connections we put NULL.
2819 * For router sending packets locally means now always sending the
2820 packet cell wide; to local clients and local servers. For normal
2821 server sending packet locally means sending it to only local
2824 * Fixed the JOIN command to really work in router environment. If the
2825 channel is created it is always created by the router. Router is
2826 also responsible of making the initial joining to the channel,
2827 sending JOIN notify to the sending server and distributing
2828 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2829 does not exist server doesn't do anything else but forward the
2830 command to the router which performs everything.
2832 * Added silc_server_send_channel_key function to send the Channel Key
2835 * Added silc_server_create_channel_key to create new channel key. The
2836 channel key is now re-generated everytime someone joins or leaves
2837 a channel, as protocol dictates. Note: channel->key_len is the
2840 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2842 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2843 packet_receive.[ch] to separate packet sending and receiving
2844 routines. The server.[ch] now includes everything else including
2845 actual packet processing (writing and reading data) and other
2848 Renamed silc_server_private_message_send_internal to
2849 silc_server_send_private_message. The routine is still though
2850 used only to relay private messages as server does not send
2851 private messages itself.
2853 Renamed silc_server_new_channel to silc_server_create_new_channel
2854 and added new function sicl_server_new_channel that handles the
2855 incoming New Channel packet. Added also new sending function
2856 silc_server_send_new_channel to send New Channel Payload.
2858 * Added new function silc_server_notify to process incoming notify
2859 packet to the server/router. Server may then relay the notify
2860 to clients if needed.
2862 * Added new function silc_server_new_channel_user to process incoming
2863 New Channel User packet. Router will redistribute the packet and
2864 send JOIN notify to its local clients and locally connected servers
2865 if needed. Normal server will send JOIN notify to its local client
2866 on same channel when received this packet. Added also corresponding
2867 sending function silc_server_send_new_channel_user to sent the
2870 * Added boolean route argument to send_notif_to_channel and
2871 packet_send_to_channel functions to attempt to route the packet
2872 if it is TRUE and send only locally if it is FALSE.
2874 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * silc_server_replace_id now broadcasts the received replace ID
2877 packet if it is not broadcast packet already. The router must
2878 broadcast to inform other routers about changed ID.
2880 * Added backpointer to server's router into SilcServer context in
2881 silcd/server_internal.h.
2883 * Fixed silc_server_packet_broadcast to send correct broadcast
2886 * The channel key is now distributed to the local client as soon
2887 as it is received from the router (in router environment) so that
2888 no other packet may be sent for the channel until client has
2891 * silc_server_remove_channel_user now broadcasts the received
2892 Remove Channel User packet if it is not broadcast packet already.
2893 The router must broadcast to inform other routers about removed
2896 * Added users field into SilcPacketContext that is a reference count
2897 of the context. One can increase the reference count by calling
2898 silc_packet_context_dup which is now changed to just increase the
2899 reference count instead of duplicating the data. The reference
2900 count is decresed by calling silc_packet_context_free that will
2901 free the data after the reference count hits zero.
2903 For now on the packet context and everything allocated into it
2904 (including the raw packet from network) must be freed by calling
2905 the new silc_packet_context_free function. Added also new function
2906 silc_packet_context_alloc that must be used now to allocate the
2907 context. This also means that if a routine is asynchronous from
2908 silc_[client/server]_packet_parse_type the packet context must
2909 be duplicated by calling silc_packet_context_dup. Otherwise it
2910 gets free'd after silc_[client/server]_packet_parse_type returns.
2911 Also, one must remember that if packet is duplicated then its
2912 reference count must be decresed by calling the free function as
2913 many times as it was duplicated.
2915 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2916 from both client and server.
2918 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2920 * Made joining to a channel working in router environment.
2922 * Cleaned up JOIN command on server side and create function
2923 silc_server_command_join_channel internal routine to make the
2926 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * Changed silc_command_pending list to SilcDList. Also, added
2929 `ident' field to SilcServerCommandPending structure to identify
2930 the reply and to call correct callback.
2932 Added silc_server_command_pending_check function to replace the
2933 corresnponding macro. The silc_command_pending list is not
2936 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2937 to set identifier to previously allocated Command Payload. It
2938 is used to set identifier for command when resending Command
2941 * Added silc_command_payload_encode_payload to encode Command
2942 Payload buffer from SilcCommandPayload structure.
2944 * Added silc_argument_payload_encode_payload to encode Argument
2945 payload buffer from SilcArgumentPayload structure.
2947 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2949 * Changed WHOIS command to support router connection on server side.
2950 The whois request is always sent to router unless the server is
2951 standalone server. After server has received the reply from the
2952 router will it send the reply to the client.
2954 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2955 broadcast received broadcast packet. The function is used only
2956 by router. The broadcast packet is always sent to the router's
2959 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2960 render given ID to printable string, for log files for example.
2962 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * Made basic router to router connections working. At least they
2965 can now connect to each other but nothing really works the way
2966 they are supposed - yet.
2968 * Added new initiator token to RouterConnection configuration
2969 file in silcd/serverconfig.[ch]. It is used to tell whether we
2970 are the initiator to the remote router or whether we'll expect
2971 the other end to connect.
2973 * Moved registering of listener task to silc_server_init, hence
2974 the server starts listenning as soon as it is run, even if it
2975 does not have connections to other routers. Let's see how well
2978 * Changed default connection retry timeouts for more suitable in
2981 * Removed cipher and such arguments from silc_idlist_add_client
2982 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2983 Added new function silc_idlist_add_data to add the keys and stuff
2986 * Added SilcIDListData structure and added it to SilcClientEntry
2987 and SilcServerEntry as their first field in the structure. This
2988 way we can explicitly cast the ID entries to the SilcIDListData
2989 structure and get common data for the entries. In past, we had
2990 to first check what type of connection it is and then cast it to
2991 correct ID entry type. Now, we can directly cast the opaque
2992 pointer to the SilcIDListData (no matter what ID entry it actually
2993 is) and get the data needed.
2995 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2997 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2998 in some circumstances even if threre were timeout tasks, though not
2999 IO tasks, but tasks anyway. Now fixed.
3001 * Defined SilcServerConnection structure to hold connection specific
3002 stuff about directly connected servers and routers. The definition
3003 is currently in silcd/server_internal.h. I thought about having
3004 a bit more important role fro this struct but for now it is used
3005 only when connecting to other server (or router actually).
3007 * Added connecting retry support in server when connecting to
3008 router(s). The retry feature implement exponential backoff
3009 algorithm. Also, added SilcServerParams structure to hold default
3010 parameters for server. For now, it include these retry settings
3011 and are hard coded. After server is moded to be as Silc Server
3012 Library this structure will be more important.
3014 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3016 * Changed client librarys channel->clients table to SilcList and
3017 changed code accordingly.
3019 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Changed client's channel table to SilcList and changed code
3022 accordingly. Also changed SilcChannelClientEntry to include back-
3023 pointer to the channel so that client entry can use that structure
3024 as list as well and we have fast cross-reference to the channel.
3025 This change dramatically decreased the complexity of channel
3026 handling with client entry and vice versa (removed one extra
3027 loop when searching for channel entry from many functions).
3029 * Changed server->sim from table to SilcDList and changed code
3032 * NAMES command can now be used from user interface. It will show
3033 the user list on the channel, neatly.
3035 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3036 Code now saves realname of the user if it becomes available.
3038 * Renamed configure.in to configure.in.pre and made ./prepare
3039 script to automatically add correct version string to
3040 configure.in which it creates from configure.in.pre.
3042 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * NAMES command reply now shows users mode with the nickname when
3047 * Moved silc_client_ch[u]mode[_char] functions from
3048 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3049 place sucks, they are utility functions and should be in some
3052 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3054 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3057 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Added TRQ (efficient deque and list library) into lib/trq. This is
3062 a very good list library that is currently used in the SILC. Defined
3063 SilcList API over the library because I didn't like the API very
3064 much. See lib/trq/silclist.h for the API and examples of how to
3065 use the API. Fixed various places in the code to use the new
3066 SilcList API. The SilcList is meant for lists that has a structure
3067 already defined as a list. It is not suitable to add just some
3068 context to the list (in TRQ, the context is the list actually).
3070 So, I defined SilcDList that can be used for the purpose where
3071 predefined list structure does not exit. This can be used as
3072 such list. Now some context just can be added to the SilcDList.
3073 Currently this list is not used in the SILC just yet, though there
3074 are a lot places where this can replace dynamically allocated
3075 tables and I will fix these places, later, to use SilcDList.
3076 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3077 and use TRQ internally).
3079 Also fixed some annoying warning messages that the original TRQ
3080 code generated. Also minor changes to TRQ's Makefile.in.
3082 * Added support for querying by Client ID to both WHOIS and
3083 IDENTIFY commands into server, as required by the protocol.
3085 * Removed method function pointers from SilcBuffer structure. They
3086 weren't used to anything and just increased the context size for
3087 no good reason. This change also made silc_buffer_alloc and
3088 silc_buffer_free functions inline functions.
3090 * Disabled command flooding detection support until it's fixed so
3091 that it accepts commands in but does not execute them more than once
3094 * Added silc_net_localhost(), to return local hostname, into
3095 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3096 that must be initialized before calling silc_client_init.
3098 * Added new function: silc_server_send_notify_on_channels to send
3099 notify messages to all channels client has joined. It is assured
3100 that the message is sent only once per client.
3102 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3103 lib/silcutil/silcutil.[ch] as silc_format function. The new
3104 function is generic and is used by server as well, not only by
3105 the logging routines.
3107 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3108 the provided version string was not acceptable. Added new function:
3109 silc_ske_check_version into lib/silcske/silcske.h. The function
3110 must be implemented by the application (client or server) and it
3111 does not reside in the SKE library. The function checks the version
3112 string remote end sent.
3114 * Added back pointers (to opaque context and to SilcSocketConnection)
3115 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3117 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3118 duplicate packet context structure.
3120 * Changed `notify' client operation to send same arguments as client
3121 receives from server except for ID's. ID's are mapped to correct
3122 ID entry and that is returned. Also, if channel entry is not sent
3123 by server but the notify is for channel the channel entry is sent
3124 to application (otherwise application doesn't know that it is for
3125 channel (library gets it from packet's Destination ID)).
3127 * Added silc_client_remove_from_channels into client library to
3128 remove a client from all channels it has joined to. Used when
3129 received SIGNOFF notify from server. Added also new function
3130 silc_client_replace_from_channels to replace old ID entry with
3131 new ID entry on all channels. Used when received NICK_CHANGE
3134 * Fixed ID Cache list handling in silc_idlist_get_client in
3135 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3136 to get (or query) client by ID.
3138 * Updated TODO list.
3140 * Added connection authentication status message defined by the
3141 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3142 support for these into the code in client and server side.
3144 * Added generic function silc_client_send_command to send any command
3145 with variable argument list. Application should use this function
3146 to send commands if the command functions provided by the library
3147 does not suite for the application's user interface needs.
3149 * Added new `failure' client operation. Application is notified about
3150 received failure packet if client is executing a protocol. In this
3151 case the protocol's execution has failed.
3153 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3154 is required by the protocol.
3156 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3157 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3160 * Added status flag to SilcSKE object to indicate realtime status
3161 of the SKE protocol.
3163 * Application receives now exactly same command reply arguments as
3164 the library receives from server. However, if ID is received the
3165 corresponding ID entry is returned to the application (eg. Client
3166 ID is mapped to correct SilcClientEntry entry and that is returned).
3167 Changed command_reply client operation due to this change.
3169 * Changed all ID's in commands and in command replys as ID Payloads.
3170 Change affected both client and server side codes.
3172 All ID's sent in SILC network (with execption of ID's in SILC
3173 Packet header) are sent in ID Payload to support variable length
3176 * Server now notifies nick changes and notifies all clients on
3177 the channels about the new nickname (about the new Client ID,
3180 * Implemented CMODE command to change channel modes. Supports all
3181 channel modes defined by the protocol specs except ban and invite
3182 lists. (Also, private channel key mode is supported but support for
3183 setting private channel key in client is missing, thus, this mode
3184 has no effect on client side (except that server requires that the
3185 client uses private channel key and normal channel traffic does not
3188 Also, invite mode works per se, but INVITE command does not work
3189 yet correctly, so you can set channel as invite only channel but
3190 inviting clients to the channel does not work (it is yet to be
3191 thought what's the best way to do it).
3193 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3194 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3195 Implemented CUMODE command to change user's mode on the channel.
3196 Supports all modes defined by the protocol specs.
3198 * Added NAMES command reply to return users modes on the channel.
3200 * Removed unnecessary and slow ciphers from lib/silccrypt.
3202 * Set SO_KEEPALIVE option to connection sockets by default.
3204 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3206 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3207 redefined the Notify Payload into protocol specs.
3209 * Added silc_id_payload_parse_id to get ID directly from raw
3212 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3215 accept searching by Client ID as well.
3217 * Added support for LEAVE and SIGNOFF notify types in client library.
3219 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3220 to parse ID Payload from raw data.
3222 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Added flags parameter into silc_ske_assemble_security_properties
3225 function in lib/silcske/silcske.[ch].
3227 * Changed notify client operation to fit better for notify messages
3228 sent by server. The notify payload received from server is now
3229 passed to the application (after parsing it to SilcNotifyPayload).
3230 It is application's responsibility to retrieve the arguments
3231 from the payload and show the message the way it wants. The message
3232 sent by server is implementation specific.
3234 * Changed public keys to comply with the protocol specification.
3235 Old public keys are not supported anymore and are not compatible.
3237 * Removed nickname from Channel Payload as the latest draft removed
3238 it. The client must resolve the nickname from the NAMES command
3239 reply received when it joined the channel.
3241 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3243 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3245 * Fixed some errors in protocol specification drafts.
3247 * Created lib/silccore/silcnotify.c to implement Notify Payload
3248 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3249 generic payloads described by protocol specifications. The file
3250 includes implementations for ID Payload and Argument Payload.
3252 * Changed Command Payload implementation to use the new Argument
3253 Payload. Changed command_xxxx_payload to command_payload_xxxx
3254 to comply with SILC coding conventions.
3256 * Added suppport for Argument Payload handling in Notify Payload
3257 implementation as protocol requires it. Added the new support
3258 into server and client lib as well.
3260 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Added support for multiple nicknames on same channel. [n] is
3263 added locally to the nickname if there are more than one same
3264 nicknames on the channel.
3266 * Server now sends all nicknames that matched WHOIS request.
3267 Client also shows the list received from server.
3269 * Added TOPIC command to client side. User can now set and show
3270 current topic on channel.
3272 * Added MOTD command to client and server. Also, server sends the
3273 motd when client connects to the server.
3275 * Changed version strings to comply ISO 8601.
3277 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Fixed protocol error handling in client library. It should now
3280 cope even if the SKE fails for some reason.
3282 * Made new protocol specification drafts for submitting to IETF.
3284 * Implemented TOPIC command to server in silcd/command.c.
3286 * Added two new notify types into lib/silccore/silcnotify.h:
3287 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3288 notify nickname change and topic setting/change on a channel.
3290 * API change of command_reply operation in client library. The
3291 application gets now the status type received from server as well.
3293 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3295 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3297 * Cras fixed and optimized the packet handling even further and
3298 it should work now. Minor change to the prototype of function
3299 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3301 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Added new function into lib/silcutil/silcschedule.[ch]:
3304 silc_schedule_with_fd to select() a specified fd. The function
3305 returns after timeout expires or data arrives or goes. The
3306 function is used by packet routines to wait that all data is
3307 received from network.
3309 * Fixed data reading from network in lib/silccore/silcpacket.c.
3310 The code now assures that all data is read from the fd and then
3311 continues packet processing. This was a bug fix since the code
3312 used to drop some data in some circumstances.
3314 * Added new function into lib/silcclient/client.[ch]:
3315 silc_client_start_key_exchange to start key exchange after
3316 connection has been established to server. The code internally
3317 now uses this funtion but its main purpose was to provide it
3318 for applications that perform their own connecting. After
3319 application has created a connection it merely calls this
3320 function to start the key exchange between client and server.
3321 The library takes care of everything else after that.
3323 Updated also lib/silcclient/README to explain the usage of
3326 * Do not send to application information that connection has
3327 been established. Application gets notified it by connect
3330 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Applied cras's patch to add silc_schedule_one function. The
3333 function runs scheduler once and returns.
3335 * Fixed the scheduler after cras messed it up. The timeout
3336 handling works now as it's supposed to work.
3338 * Added into lib/silccore/ silcnotify.h to include notify
3339 message types support. Changed silc_server_send_notify*
3340 functions, in server.[ch], to support those new notify types.
3341 Added the support for the notify types into client library,
3342 as well. Added new notify client operation into ops.h in
3345 * Changed silc_server_packet_send_to_channel to send normal
3346 packets instead of just channel message packets. The function
3347 is now used to send the notify packets to channels. It is not
3348 used to send channel message packets anymore, as server never
3351 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3352 va_arg()s as it seems to require it nowadays. I guess, if SILC
3353 is compiled with older va_arg() the new code should work anyway.
3355 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Splitted core library. Core library (lib/silccore) includes
3358 now only SILC protocol specific core (and common) components.
3359 Created new utility library (lib/silcutil) that includes more
3360 generic purpose stuff. The stuff for util library was taken
3361 from the old core library. This was minor and easy split.
3363 * Created SILC Client Library (lib/silcclient) that includes
3364 implementation of the SILC client without user interface. This
3365 was major move from silc/ directory. The code has been changed
3366 so that it is transparent towards the user interface. The
3367 silc/ directory includes now the same user interface as before
3368 and it uses the new client library. Read lib/silcclient/README.
3369 Basicly, the client library performs everything else related
3370 to SILC except user interface handling. Also, configuration
3371 files are considered to be part of user interface and library
3372 does not handle them.
3374 This change also changed a lot of structures, function naming etc.
3375 Most important change was that SilcClientWindow object was
3376 renamed to SilcClientConnection in the client library. Created
3377 also new file lib/silcclient/ops.h. Also added new files
3378 silc/local_command.[ch] and silc/client_ops.[ch].
3380 All these changes were made to make it easier for user interface
3381 designers to create what ever user interface for the SILC client
3384 It is also expected that the server will be moved to lib
3385 directory as well and SILC Server Library will be created;
3386 sometimes in the future.
3388 * Removed Local commands from lib/silccore/silccommand.h as
3389 they are application specific and new client library does not
3390 handle any of those anymore.
3392 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3393 old client implementation in silc/.
3395 * Added support for callback functions in SILC_LOG_* macros.
3396 Application can now set its own callbacks that will be called
3397 instead of using the default functions that will always print
3398 the debug messages to stderr (or stdout). Also, debugging can
3399 now be disabled by setting silc_debug to FALSE and re-enabled by
3400 setting it to TRUE. Note, that logging will still work even
3401 if debugging is disabled.
3403 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3404 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3405 silc_log_reset_debug_callbacks.
3407 * To enable debugging in silc client one must give now -d
3408 option on command line.
3410 * Changed silc_schedule_init to automatically allocate task queues
3411 if they are not allocated before calling it.
3413 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Added GMP 3.1 into math library.
3417 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3420 a channel in SILC network. The packet is used by servers and
3421 routers to notify other routers that user has left a channel.
3422 This little feature was missing until now. Added the feature
3423 to protocol specification as well.
3425 Added functions: silc_server_send_remove_channel_user and
3426 silc_server_remove_channel_user into server.[ch].
3428 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3429 lib/silccore/silcpacket.h. However, they are not implemented
3432 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3434 * Fixed joining to a channel and sending channel messages
3435 between server and router. The channel message sending should
3436 now work inside a cell.
3438 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Fixed the private message sending between server and router.
3441 The private message sending should now work inside a cell.
3443 * Added silc_server_replace_id into server.[ch] to replace
3444 existing ID in the SILC network.
3446 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3447 and silc_idlist_replace_server_id into idlist.[ch] in server.
3449 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3451 * Fixed the server to server connections. Server can again now
3452 connect to router. Router to router connections probably does
3455 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Added dynamic protocol registering support. Now protocols can
3458 registered and unregistered on the fly. Patch by cras.
3460 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3462 * Added lib/contrib directory to hold routines that some platforms
3463 don't have but are needed by SILC.
3465 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3466 into lin/contrib to provide getopt() and getopt_long() for
3467 those who don't have it.
3469 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Added AWAY command to client. When away message is set and
3472 client receives a private message packet the client automatically
3473 replies to the sender with the away message.
3475 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3476 bug seemed to be the cause of recent problems when compiling
3479 * Added version detection support to SKE protocol specification
3480 and added the new changes to the SKE implementation as well.
3481 There were other minor changes in the SKE protocol as well.
3483 Many changes in lib/silcske/silcske.[ch] and in
3484 lib/silcske/payload.[ch].
3486 * Added ^U functionality, clear input line. Patch from cras.
3488 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3490 * Mainly small bugfixes on core library. Fixed some debugging
3491 logging and buffer overflow in silclog.c.
3493 * Updated config.sub and config.guess on the distribution tree.
3495 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * Added command lagging support in server. Client may execute
3498 commands now only once in two seconds.
3500 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Optimized packet reception. MAC computation and checking is now
3503 also more optimized. A lot previously duplicated code is now
3504 used as generic by both client and server.
3506 * Fixed key pair generation in clientutil.c
3508 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Added into lib/silccore/silcbufutil.[ch] new function;
3511 silc_buffer_realloc.
3513 * Moved generic packet sending/encryption functions to
3514 lib/silccore/silcpacket.[ch] from client and server. Some
3515 rewriting of the functions.
3517 * Moved all generic packet reception/decryption functions to
3518 lib/silccore/silcpacket.[ch] from client and server. The
3519 packet processing is now much cleaner in both client and server.
3520 These were major changes in both client and server.
3522 * Created many common functions in server to do packet sending.
3523 Previously code were duplicated a lot, this has been removed
3526 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Rewrote major parts of the ID cache system. Don't know
3529 whether it is better now or not but at least the API is more
3532 * Major rewrite on ID cache stuff on client because of the ID
3533 cache API changes. Added idlist.c to client.
3535 * Also major rewrite on ID cache stuff on server as well.
3536 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3537 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3538 in hand, instead they are all put into the ID cache system now.
3539 All server_idlist_* routines uses ID cache now instead of
3540 traversing its own lists (those lists does not exist anymore).
3541 SilcIDList though still exists. Also, SilcXXXEntry's are
3544 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * Finally made the SKE implementation compliant to the protocol
3547 specification. All mp integers are now binary encoded as
3548 opposed being HEX encoded.
3550 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3553 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3554 functions: silc_[encode/decode]_pem. Also added function
3555 silc_encode_pem_file to PEM encode with newlines ('\n') for
3558 * SILC public keys are now encoded either PEM or binary. Same
3559 option is for private keys as well. By default private keys
3560 are binary encoded and public keys PEM encoded. Silly HEX
3561 encoding were removed.
3563 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3564 function to create fingerprints.
3566 * Fixed a bug in SHA1; does not change the original data anymore.
3568 * Partly implemented INFO command on client and server side.
3569 Fixed CLEAR command. Changes to SERVER command; show current
3570 server(s) when giving command without arguments. Added
3571 VERSION command to client.
3573 * Added check to server that unregistered connections cannot
3574 execute commands (unless it is specificly allowed).
3576 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * Fixed screen refresh.
3580 * Fixed channel joining bug from client. On some circumstances
3581 client tried to join to a channel it had already joined.
3583 * Added public key verification process into client's protocol.c.
3584 The client now verifies the public key from user and saves
3585 it into ~./silc/serverkeys/ directory.
3587 Added into: clientutil.[ch]: silc_client_verify_server_key.
3589 * Changed SKE protocol's silc_ske_initiator_finish function
3590 to accept callback function that verifies the received public
3591 key. Removed old silc_ske_verify_public_key function.
3593 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3595 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3596 silc_pkcs_private_key[_data]_set.
3598 * Made the password and public authentication more cleaner in
3599 server's protocol.c.
3601 * Removed historic and obsolete protocol `channel_auth' from
3602 both client and server.
3604 * Removed wrong way of sending command status messages from
3605 server to client in server's command.c. The old way violated
3606 protocol specification.
3608 Changes to silccore/silccommand.[ch]: removed
3609 silc_command_encode_status_payload -> not needed anymore,
3610 changed silc_command_encode_payload_va to accept extra
3611 argument on variable argument list. The argument type must
3612 now be provided to the function. Also, added new function:
3613 silc_command_encode_reply_payload_va which is same as
3614 normal command_encode_payload_va except command status type
3615 is provided as extra argument.
3617 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3619 * Added ~./silc directory handling. The directory includes the
3620 public and private keys for the client.
3622 Added silc_client_check_silc_dir, silc_client_create_identifier
3623 and silc_client_load_keys.
3625 * Implemented SILC protocol compliant public key. Added public
3626 and private key saving to and loading from files.
3628 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3629 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3630 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3631 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3632 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3634 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3635 silc_pkcs_load_[public/private]_key.
3637 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3639 * Added silc_server_get_route (route.[ch]) to get connection
3640 data for the fastest route for given ID.
3642 * Implemented INVITE command on client and server. The command
3643 were re-defined in the SILC Protocol Specification and the
3644 implementation now complies with the specification.
3646 * Implemented PING command on client and server.
3648 * Implemented NAMES command on client and server. The server side
3649 supports currently only normal server not router server yet.
3650 Some changes to NAMES definition in SILC protocol specification.
3652 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Implemented LEAVE command on client and server.
3656 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3657 again. This change was made to the protocol as well. Server
3658 should not violate the protocol specification anymore.
3660 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3663 was tested. SOCKS4 was not but should work anyway.
