1 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added new function silc_idcache_del_by_context into the
4 lib/silccore/idcache.[ch].
6 * Changed the server's ID list routines to use the new ID Cache
7 interface. Changes around the source tree.
9 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
11 * Added silc_hash_table_del[_by_context]_ext functions in to the
12 lib/silcutil/silchashtable.[ch].
14 Removed silc_hash_table_find_all* routines and added new
15 silc_hash_table_find_foreach to replace them.
17 Added silc_hash_table_replace_ext function as extended
18 replacing function. Separated the simple hash table interface
19 from the extended hash table interface in the file
20 lib/silcutil/silchashtable.h.
22 * Fixed minor bugs and changed it to use some of the new
23 hash table functions in lib/silccore/idcache.c
25 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
27 * Added new function silc_hash_table_find_all to return all keys
28 in the hash table by the specified key. As the hash table is
29 collision resistant it also makes it possible to have several
30 duplicate keys in the hash table. This function may be used to
31 find all of the keys from the hash.
33 Added user_context arguments to the SilcHashFunction,
34 SilcHashCompare and SilcHashDestructor to deliver user specified
37 Added new fuctions silc_hash_table_find[_all]_ext to do
38 extended lookup with specified hash and compare functions and
39 specified user contexts.
41 Added new function silc_hash_table_add_ext to add the key
42 with specified hash function and user context.
44 Added new function silc_hash_table_foreach to traverse all
45 entrys in the hash table. Added SilcHashForeach callback
48 Added new function silc_hash_table_del_by_context to delete
49 the entry only if the context associated with the key matches.
51 Affected files are lib/silcutil/silchashtable.[ch].
53 * Removed silc_hash_[server/client/channel]_id and added just
54 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
55 silc_hash_id_compare to compare two ID's using as the hash table
56 comparison function. Added also silc_hash_data to hash
57 binary data and silc_hash_data_compare to compare it.
59 * Removed silc_idlist_find_client_by_hash as it is not needed
60 anymore. Affected file silcd/idlist.[ch].
62 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
63 to use internally the SilcHashTable. The new ID Cache is a lot
64 faster than the old one. Some of the ID Cache interface was also
65 rewritten and obsolete and stupid functions were removed.
67 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
69 * Added entry_count field to the SilcHashTable to keep the number
70 of the entries in the table. Implemented the function
71 silc_hash_table_rehash. Added new function
72 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
74 Fixed a minor bug in silc_hash_table_free.
76 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
77 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
78 into the lib/silcutil/silcutil.[ch].
80 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
82 * Implemented a collision resistant hash table into the
83 lib/silcutil/silchashtable[ch]. See the header and the source
84 for the SilcHashTable API.
86 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
88 * Merged dotconf version 1.0.2 into lib/dotconf.
90 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
92 * Do not compile anything in lib/silcsim/* if the SIM support
93 is not enabled. The tree should now compile without problems
96 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * Compiled the SILC under cygwin. Compiled and tested briefly
99 without problems. More tests needed. The SIMs didn't compile
102 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
104 * Fixed possible crash in silc_get_username in the
105 lib/silcutil/silcutil.c.
107 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Fixed a va_arg in silc/client_ops.c.
111 * Oops, RC5 routines were named AES and caused some problems
112 when not using SIM's. Affected file lib/silccrypt/rc5.c.
114 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
116 * Added new SilcIDIP structure into the lib/silccore/id.h and
117 replaced the old `ip' fields from all SILC ID's to that type.
118 This is a step towards IPv6 support.
120 The silc_id_get_len takes now the ID as an extra argument.
121 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
122 both IPv4 and IPv6 based ID's.
124 The affected files are lib/silccore/id.[ch] and other files
125 around the tree using these routines.
127 * Removed the ID length arguments in server from various
128 silc_server_send_notify_* routines -> they are not needed
131 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
133 * Fixed memory leak in silc_encode_pem_file in the file
134 lib/silcutil/silcutil.c.
136 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
138 * Check minor version as well in the SKE. Affected files are
139 silcd/protocol.c and lib/silcclient/protocol.c.
141 * Added --identifier option to the server so that an identifier
142 can be when creating the public key for the server. Affected
143 file is silcd/silcd.c.
145 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
146 lib/silccrypt/silcpkcs.c.
148 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
150 * Register default ciphers and stuff when using -C option with
151 the server. Affected file sildc/silcd.c.
153 * Put back the servers public key filename format, it is better
154 than the new one. For now, the client keys are saved with the
155 new filename format. The affected file silc/client_ops.c.
157 * Implemented the Cipher API for the rest of the ciphers that
158 did not implement it or implemented it the wrong way.
160 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
162 * Register default ciphers and stuff when using the -S option
163 in the client. Affected file silc/silc.c. Same also when
164 creating new key pair with -C option.
166 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
168 * Fixed the silc_verify_public_key client operation function to
169 save the public keys differently. The fingerprint is now
170 used as filename and not the hostname. This way also the
171 client keys are saved uniquely and not with hostnames. The
172 affected file is silc/client_ops.c.
174 * Trimmed the silc_hash_fingerprint function to remove extra
175 whitespaces from the end of the fingerprint. The affected
176 file is lib/silccrypt/silchash.c.
180 * Added silc_cipher_register_default function to register all
181 default ciphers. It can be used when configuration files
182 does not exist and the application does not want any specific
183 ciphers in any specific order.
185 The SilcDList is now used as silc_cipher_list dynamically
186 allocated cipher list. Removed the static list all together
187 and now all ciphers must be allocated to the dynamic list.
188 The silc_cipher_alloc routine was changed to check only the
191 All silc_cipher_* routines that used to return int returns
194 The affected files lib/silccrypt/silccrypt.[ch].
196 * The same thing was done to silc_hash_* as for silc_cipher_*
197 routines. Affected files lib/silccrypt/silchash.[ch].
199 * The same thing was done to silc_pkcs_* as for silc_cipher_*
200 routines. Affected files lib/silccrypt/silcpkcs.[ch].
201 Added also silc_pkcs_[un]register[_default] functions.
202 Removed the data_context from the PKCS API.
204 * Added silc_hmac_register_default function to register default
205 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
206 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
207 to unregister all hmacs at once.
209 * Register the default ciphers, hash functions, PKCSs and HMACs
210 if client's configuration file does not exist. The affected
213 * The client did not load the hash functions from the SIM
214 modules at all. Added support for this. Affected file is
217 * When decoding public key with silc_pkcs_public_key_decode, check
218 the supported algorithm only if PKCS are registered. Affected
219 file lib/silccrypt/silcpkcs.c. The same was done with the
220 silc_pkcs_private_key_decode.
222 * Fixed the SILC List routines to keep the list always in order.
223 It used to change the list's order when traversing the list but
224 not it preserves the order. Affected file lib/trq/silclist.h.
226 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
228 * Added the client library to use the SilcSocketConnection's
229 reference counter (by silc_socket_dup) to prevent the bug that
230 the socket object may be freed underneath async operation.
232 * The name resolv library checking fixes in the configure.in.pre.
235 * Created new version of the protocol drafts for future
236 development. The -03 drafts are the ones that will be changed
237 in the trunk now and the -02 will remain as they are.
239 * Send list of CUMODE notifys to the router when announcing
240 the channel users to the router. Affected file silcd/server.c.
241 If the router receiving channel founder CUMODE for a channel
242 that already has channel founder it will send CUMODE notify
243 to the sender to remove the channel founder rights from the
244 announced client. Affected file silcd/packet_receive.c.
246 * The CUMODE notify may now use Server ID as well as the entity
247 who changes the mode. Updated protocool specs.
249 * Updated INSTALL and README files.
251 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
253 * New web pages in the http://silc.pspt.fi. The pages was
258 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
260 * Implemented the [DenyConnectin] config section in the server.
261 Added silc_server_config_denied_conn to check whether incoming
262 connection is denied. Affected file silcd/serverconfig.[ch].
264 * Do not check the ports when checking the incoming configuration
265 data if the port is 0, meaning any. Affected file is
266 silcd/serverconfig.c.
268 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
270 * Fixed buffer overflow in silc_string_compare in the file
271 lib/silcutil/silcutil.c.
273 * Fixed double free in silc_server_command_leave in the file
276 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
278 * Fixed the version checking in the server. Affected file is
281 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
283 * Fixed the configuration data fetching when accepting new
284 connections in the server. Affected file silcd/server.c.
286 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * Added `sender_entry' argument to the function
289 silc_server_packet_relay_to_channel so that we can check
290 whether some destination actually belongs to the same route
291 the sender belongs (ie, we must not resend the packet to the
292 sender). Affected file silcd/packet_send.[ch].
294 * Added `servername' field to the SilcClientEntry in the server
295 to hold the name of the server where client is from. Affected
296 file is silcd/idlist.h.
298 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
300 * Moved the channel message encrypting in the router betwen
301 router connections from silc_server_channel_message to the
302 silc_server_packet_relay_to_channel since we want to check
303 whether we have anybody channel before encrypting anything.
304 Affected files silcd/packet_[receive/send].c.
306 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
308 * Fixed the [AdminConnection] server config section to support
309 multiple entries. Affected file silcd/serverconfig.c.
311 * Added support into the server to check the validity of the
312 incoming connection before executing any KE or authentication
315 * The connection configuration is now saved to the KE and
316 connection auth protocol contexts and not fetched anymore in
317 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
319 * The local hosts listenning address and port is also resolved
320 now when starting the server. We want to have the socket object
321 to include the real address and port for the listener. Added
322 new function silc_net_check_local_by_sock into the files
323 lib/silcutil/silcnet.[ch].
325 * Fixed a broadcast bug in server -> do not broadcast if we
328 * Fixed a routing bug. Do not route broadcast packets ever.
329 Broadcast packets must be processed always and not routed since
330 they may be destined to some other host than yourself and thus
331 would get routed without no good reason. Affected file is
334 * Added function silc_server_config_is_primary_route to check
335 whether primary router connection has been configured (a router
336 configuration that we are initiating). If there is not, we
337 will assume that there is only two routers in the SILC network
338 and we will use the incoming router connection as our primary
339 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
341 * Changed the order of the broadcasting. Broadcast _after_ the
342 packet has been processed not before. Affected file is
345 * Fixed a [ClientConnection] parsing bug. The port was never
346 parsed correctly thus resulting to port 0. Affected file
347 silcd/serverconfig.c.
349 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
350 argument and did not set the broadcast packet flag. Affected
351 file silcd/packet_send.c. Fixed same bug in the function
352 silc_server_send_notify as well.
354 * If we receive NEW_ID packet for our own ID in the server, ignore
357 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
361 * Removed the nickname from the Private Message Payload.
362 Updated the code and the protocol specs.
364 * Updated protocol specs for submitting to the IETF.
366 * Tweaked the Random Number Generator a bit. Affected file
367 lib/silccrypt/silcrng.c. Exported a new function
368 silc_rng_[global]_add_noise which can be used to add more
371 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
373 * Do not parse packets with different timeout when protocol
374 is active -> may cause problem with rekey. Affected file
377 * When server receives signoff notify it must not create
378 new channel key if the client is on any channels since the
379 sender of the signoff notify will create it.
381 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
383 * Added printing of error messages during SKE protocol from the
384 failure packet sent by server during SKE. Affected file
387 * Removed the client's failure_callback handling with timeout
388 and handle it immediately when received.
390 * The SKE library returned wrong type in SUCCESS and FAILURE
391 packets. They must be 32 bit MSB not 16 bit MSB.
393 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
395 * Ok, rewrote the logic of the re-key and now it seems to work.
396 I tested it on high traffic with frequent re-keys without
397 problems. Added hmac_receive (and renamed hmac to hmac_send)
398 in SilcClientConnection in lib/silcclient/client.h and
399 in SilcIDListData in silcd/idlist.h. Also, removed the
400 SilcPacketParserContext's cipher and hmac fields as they are
401 not needed anymore and actually caused some problems when
402 the ciphers and hmac's changed underneath the packet parser.
404 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * If re-key protocol is active then process the incoming packets
407 synchronously since we must assure that icoming packets encrypted
408 with the old key is processed before the new keys is set to
409 use. This is true other packets than for REKEY packets.
410 Affected file silcd/server.c. The same was done to client library
411 as well, affected file lib/silcclient/client.c.
413 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
415 * Fixed bug in client and server to accept the force send if
416 the packet is send from silc_[server/client]_packet_process
417 function. Otherwise the packets are never delivered, oops.
419 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
421 * Disable force sending of packets when REKEY protocol is active.
422 We must assure that no packet is sent directly when rekey is
423 performed. All packets must be sent through packet queue.
424 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
425 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
426 function is silc_[server/client]_packet_send_real to check
429 * Replaced the SIM paths from example config files to
430 /usr/local/modules. Also, make install creates now
431 /usr/local/silc/logs directory to hold all the SILC server
434 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
436 * Made the configure.in.pre work on Solaris. Patch by salo.
438 * Made all ciphers compatible with non-x86 machines. Defined
439 CBC mode macros into lib/silccrypt/ciphers_def.h.
441 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
443 * Fixed the make install.
445 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
447 * When MAC computation fails the silc_packet_decrypt returned 0
448 even though it was supposed to return -1. Fixed this. The
449 affected file is lib/silccore/silcpacket.c.
451 * Do not replace the config files in /etc/silc (in make install)
452 if they already exist. Affected file ./Makefile.am.
454 * Do not send re-key packets immediately but through packet queue.
455 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
457 * Changed silc_net_check_host_by_sock to return FALSE if the
458 IP/DNS could not be resolved. Though, it returns the IP address
459 now even if it could not resolve it (but returns also FALSE).
460 Affected file lib/silcutil/silcnet.[ch].
462 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
464 * Added silc_pkcs_decode_identifier to decode the public key's
465 identifier. Affected file lib/silccrypt/silpkcs.[ch].
466 Added also silc_pkcs_free_identifier. Added also new context
467 SilcPublicKeyIdentifier.
469 * Added -S option to the silc client. It is used to dump the
470 contents of the specified public key file.
472 * Changed the PKCS api to return the public key length when
473 setting the public key.
475 * Fixed a fatal bug in the public and private key file loading.
476 Affected file lib/silccrypt/silcpkcs.c.
478 * Execute the packet parsing for client with zero (0) timeout
479 if the protocol is active. Affected file silcd/server.c.
481 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
483 * Made the key generation options to the silcd program. Added
484 -C option, equivalent to client's option.
486 * Added new [ServerKeys] config section to the server. It
487 configures the server's public and private key.
489 * Defined generic Public Key Payload into the protocol
490 specification to send specific type of public keys and
493 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
494 public key or certificate.
496 * Implemented the GETKEY command to the server and to the
497 client library and on user interface.
499 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
501 * Made preliminary `make install' work.
503 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
505 * Added SilcServerRekey context into silcd/idlist.h.
507 * Added the PFS support as defined in the specification to the
508 SKE protocol. Affected files lib/silcske/*.c.
510 * Added `ske_group' field to the SilcServerRekey context to hold
511 the number of the SKE group that is used with PFS in re-key.
512 Affected file silcd/idlist.h.
514 * Added PFS re-key support to the server. Affected file is
517 * Added silc_protocol_cancel to cancel execution of the next
518 state of the protocol. Affected file is
519 lib/silccore/silcprotocol.[ch].
521 * Added the re-key support with and without PFS to the client
522 library. Re-key is performed once in an hour, by default.
524 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
525 Added silc_client_rekey_callback and silc_client_rekey_final.
526 Affected files are lib/silcclient/protocol.[ch] and
527 lib/silcclient/client.[ch].
529 * Removed the `hmac_key' and `hmac_key_len' fields from the
530 SilcClientConnection structure; not needed. Affected file is
531 lib/silcclient/client.h.
535 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
537 * Do not ask whether user wants to use the negotiated private key
538 for private messages, just use it. Affected file is
539 silc/local_command.c.
541 * Added `send_enc_key' and `enc_key_len' fields to the
542 SilcIDListData structure since they are needed in the re-key
543 phase. Affected file is silcd/idlist.[ch].
545 * Implemented the simple re-key protocol into the server.
546 Affected files silcd/server.c and silcd/protocol.[ch]. The
547 re-key will be performed once in an hour, by default.
549 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
550 Added silc_server_rekey, silc_server_rekey_callback and

553 * Removed Tunneled flag from the protocol. Updated the code
554 and the specifications.
556 * Adde `pfs' field to the SilcIDListData to indicate whether
557 the PFS is to be performed in the re-key. Affected file is
560 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
562 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
563 int64 of at least the xintXX size. If void * is less that 4
564 bytes uint32 * will be used. Defined bool as boolean.
566 * Changed _ALL_ unsigned long and unsigned int to uint32,
567 unsgined short to uint16 in the source tree.
569 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
570 not handle clients that has entry->data.registered == FALSE.
571 They are not in the network anymore. Affected file is
574 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
576 * Implemented the sending of the SERVER_SIGNOFF notify in the
577 server. Affected file is silcd/server.c.
579 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
580 Added also silc_notify_payload_encode_args into the
581 lib/silccore/silcnotify.[ch].
583 * Implemented ther SERVER_SIGNOFF notify handling in the server.
584 Affected file silcd/packet_receive.c.
586 * Implemented the SERVER_SIGNOFF notify handling in the client
587 library. Affected file lib/silcclient/client_notify.c. Also,
588 implemnted the printing of the SERVER_SIGNOFF info to the
589 application. Affected file silc/client_ops.c.
591 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
592 if the deleting was successful. Affected file silcd/idlist.[ch].
594 * Added support for public key authentication in the connection
595 authentication protocol in the client library. Affected file
596 lib/silcclient/protocol.c.
598 * Changed the server's silc_idlist_get_clients_by_* interface
599 to support already allocated array so that new entries may be
600 added to pre-allocated array. Affected file silcd/idlist.[ch].
601 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
604 * All command reply functions in the server now calls the
605 pending command callback even if error occured. This way the
606 error will be delivered to the client as well. Affected files
607 silcd/command.c and silcd/command_reply.c.
609 * Fixed INFO command to return local server's info if no server
610 was provided. Affected file lib/silcclient/command.c.
612 * Removed RESTART command for good. Updated the code and the
615 * Rewrote parts of the task system. It is a bit simpler now.
616 Removed unsued task priorities. The affected files are
617 lib/silcutil/silctask.[ch].
619 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
621 * Moved the USERS printing from the library to the application.
622 Affected files lib/silcclient/command.c and silc/client_ops.c.
624 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Added channel key re-key support. The re-key is perfomed
629 only by the router and is done once in an hour. Added `rekey'
630 field to the SilcChannelEntry in the server. Affected files
631 silcd/server.c and silcd/idlist.h.
633 * Added silc_task_unregister_by_context into the file
634 lib/silcutil/silctask.[ch].
636 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
638 * Added SILC_UMODE_GONE mode to indicate when the client is not
639 present in the SILC network. Added also support to the local
640 command AWAY that will set this mode. Added support of showing
641 "xxx is gone" in WHOIS command. The USERS command shows the
644 * Fixed setting server and router operator privileges in the
645 server's UMODE command. Affected file silcd/command.c.
647 * Merged the SKE KE1 and KE2 payloads into one payload. The
648 new KE payload is equivalent to the old KE2 payload.
650 Cleaned up the SKE Start Payload parsing. It now uses the
651 simple buffer unformatting to do the parsing. A lot faster
654 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
655 to the SKE that is used to indicate whether both of the SKE
656 parties should perform authentication. By default only the
657 responder performs authentication. By setting this flag also
658 the initiator must do authentication. By default it is unset
659 since in normal SKE case, client to server connection, only
660 the responder should do authentication. When doing SKE between
661 two clients both should perform authentication. Updated the
662 code and the protocol specs.
664 * A little fix to IDENTIFY command in the server. Search the
665 client first by hash not nickname. Affected file is
668 * Fixed the silc_client_close_connection to support closing
669 the client to client connections wihtout deleting too much
670 data. Affected file lib/silcclient/client.c.
672 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
673 are received if protocol used to be active but is not anymore
674 the application would crash due to NULL pointer dereference.
675 Affected files silcd/server.c and lib/silcclient/client.c.
677 * Added `hash' field to the SilcClientConnection to include
678 the hash function negotiated in the SKE protocol.
680 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
681 to set the channel founder authentication data. A client can
682 claim the founder rights later by providing the authentication
683 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
684 This way the channel founder can regain the channel founder
685 privileges even it is left the channel. This works only on
686 local server and the client must be connected to the same
687 server to be able to regain the founder rights. Updated the
688 protocol specs accordingly.
690 Added support to the CMODE command in the client to set the
691 founder auth data. Read the README to see how to set it.
693 Added support to the CUMODE command to claim the founder
694 rights. Read the README to see how to do it.
696 Added support for the founder authentication to the Channel
697 Entry in the server. Affected file silcd/idlist.h.
699 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
700 server's CMODE command. Affected file silcd/command.c.
702 * Added the following new functions into lib/silccore/silcauth.[ch]:
703 silc_auth_get_method and silc_auth_get_data.
705 * The server now saves the remote hosts public key to the
706 SilcIDListData pointer. Affected file silcd/protocol.c.
708 * The normal server now does not remove the channel entry from
709 the cache if the founder authentication data is set. It used
710 to remove it if the founder was the last one on the channel on
711 the server and left the channel. The auth data is saved and
712 if the channel is re-joined later the old entry is used with
713 the old auth data. Affected files silcd/command_reply.c and
716 * Removed the `pkcs' field from the SilcIDListData structure
717 in the server; it is not used. Affected file silcd/idlist.h.
719 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
721 * Fixed packet processing on slow links. Partial packets were
722 never re-processed because the incoming data buffer was cleared
723 by the application. Application must not directly clear the
724 sock->inbuf, the packet processing routines handle it. Fixed
725 this in client library and in server.
727 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
729 * Fixed the WHOIS and IDENTIFY send reply function to really
730 check whether to send list or just one entry. Affected file
733 * Cleaned up the LEAVE command's channel key distribution. The
734 affected file silcd/command.c.
736 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
737 can enforce the channel mode as well. In that case the ID
738 includes the ID of the server. The code now enforces the
739 mode change if the router have different mode than the server.
741 * The notify client operation with CMODE_CHANGE notify can now
742 return NULL client_entry pointer if the CMODE was not changed
743 by client. Application must check for this.
745 * Added <Server ID> argument to INFO command to support server
746 info fetching by Server ID.
748 * Added silc_server_announce_get_channel_users to get assembled
749 packets of channel users of the specified channel. Affected
750 file silcd/server.[ch].
752 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
753 was freed underneath the ID Cache.
755 * Re-announce clients when the server received CHANNEL_CHANGE
756 notify from the router. Affected file silcd/packet_send.c.
758 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
760 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
761 crashed since it did not handle the fact that there is no cipher
762 called "3" and didn't check the error condition. Now fixed.
764 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
765 flag. It can be used to send message requests.
767 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
769 * Implemented the RESTART command in the client.
771 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
772 notice type messages. Added notice printing to the user
775 * The channel keys are not re-generated if the channel's mode
776 is PRIVKEY, ie private key on the channel exists. Affected
777 files silcd/server.c and silcd/command.c.
779 * Fixed a little bug in channel message delivery when channel
780 private keys are set in the server. Affected file is
783 * Changed the setting on channel->on_channel = TRUE from the
784 silc_client_save_channel_key to the JOIN command reply. The
785 key payload is not received if the private channel key is set.
786 Affected file lib/silcclient/command_reply.c and the
787 lib/silcclient/client_channel.c.
789 * When the CMODE_CHANGE notify is sent and the channel private
790 key mode is removed the channel key must be re-generated in
791 other cells as well. Added this support for the router in the
792 silcd/packet_receive.c.
794 * Added new local command NOTICE to send notice message on
795 channel. Affected file silc/local_command.[ch].
797 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
799 * Added new local command ME to the client. It is used to send
800 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
801 some action. Affected file silc/local_command.[ch].
803 * Changed channel_message and private_message client operations
804 to deliver the message flags to the application. Added also
805 the `flags' arguments to the silc_client_send_channel_message
806 and silc_client_send_private_message functions. Affected file
809 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
811 * Redefined the Private Message Payload to support private message
812 keys and to support the new private message flags. Updated
813 the protocol specs. Flags makes it possible to have for example
816 * Added new type SilcPrivateMessagePayload and defined an API
817 for it in the lib/silcclient/silcprivate.[ch].
819 * Tested private message private keys successfully. Tested the
820 private message key set, unset and list commands with the new
823 * Redefined the Channel Message Payload to include the channel
824 message flags (equal with private message flags) to support
825 for example CTCP style messages.
827 * Defined some of the message (for channel and private message)
828 flags. Updated the protocol specs and added the flags to the
829 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
831 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
833 * Added SilcKeyAgreementStatus type to the key agreement routines
834 to indicate the current status and error if one occured.
835 The status types are defined in the lib/silcclient/silcapi.h.
837 * Added new local command KEY that is used to set and unset private
838 keys for channels, set and unset private keys for private messages
839 with remote clients and to send key agreement requests and
840 negotiate the key agreement protocol with remote client. The
841 key agreement is supported only to negotiate private message keys,
842 it currently cannot be used to negotiate private keys for channels,
843 as it is not convenient for that purpose.
845 * Fixed a minor pending callback setting bug in the function
846 silc_client_get_client_by_id_resolve, now the function works.
847 Affected file lib/silcclient/idlist.c.
849 * Added function silc_net_get_local_port to get local bound
850 port by socket. Added to lib/silcutil/silcnet.[ch].
852 * Added `sockets' and `sockets_count' fields to the SilcClient
853 object. They hold the sockets of the listenning sockets in
854 the client. Listenning sockets may be for example the key
855 agreement server. Affected file lib/silcclient/client.[ch].
856 Added functions the silc_client_add_socket and the
857 silc_client_del_socket. They are exported to the application
860 * Added ~./silc/clientkeys to support other client's public keys.
862 * Renamed verify_server_key client operation to verify_public_key
863 and added one argument to indicate the type of the connection
864 (server, client etc.).
866 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
868 * Added silc_server_connection_auth_request to handle the
869 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
870 silcd/packet_receive.[ch].
872 * Added silc_server_send_connection_auth_request into the
873 silcd/packet_send.c to send the connection auth request packet.
875 * Cleaned up the silcd/protocol.c a bit and fixed some memory
878 * Fixed the public key authentication in responder side in the
879 server. The `auth_data' pointer includes the SilcPublicKey
880 not the path to the public key. Affected file silcd/protocol.c.
882 * Implemented the public key authentication in the initiator side
883 in the server. Affected file silcd/protocol.c.
885 * Removed the [RedirectClient] config section from the server
886 configuration. Is not needed and I don't want to implement it.
888 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
890 * Cleaned up the CMODE command in the server. It now works
891 correctly and supports all the modes defined in the protocol.
892 Affected file is silcd/command.c.
894 * Added `hmac_name' field to the SilcChannelEntry in the server
895 to hold the default HMAC of the channel. It can be set when
896 creating the channel (with JOIN command). Affected files
899 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
900 type to indicate the change of the current cipher and hmac
901 on the channel. Client can safely ignore the <cipher> argument
902 (if it chooses to do so) since the CHANNEL_KEY packet will
903 force the channel key change anyway. The <hmac> argument is
904 important since the client is responsible of setting the new
905 HMAC and the hmac key into use.
907 * Fixed the CMODE command in the client library as well.
909 * Tested CMODE command in router environment successfully.
911 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
913 * Show the version of the remote client (or server) when connecting
914 to the server. It is logged to the log file. Affected file
917 * Fixed the KILLED notify handling in the client library. The
918 client must be removed from all channels when receiving the
921 Also, do not remove the client entry when giving the KILL
922 command but when the KILLED notify is received.
924 * Removed silc_idlist_find_client_by_nickname from the server.
925 Not needed anymore. Affected files silcd/idlist.[ch].
927 * Implemented the CHANNEL_CHANGE notify type handling to the
928 server. Affected file silcd/server.c.
932 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
934 * Added silc_server_send_notify_invite to send the INVITE
935 notify between routers.
937 * Implemented the INVITE command correctly to the server.
939 * Implemented the INVITE notify type handling in the server.
941 * Implemented the INVITE command to the client library and on the
944 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
946 * Added function silc_server_get_client_resolve to find the
947 client entry by ID from all ID lists and then resolve it
948 (using WHOIS) if it cannot be found. Affected file is
951 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
953 * Implemented the BAN command to the client library.
955 * The JOIN command in the server now checks the invite list
958 * Changed the silc_command_reply_payload_encode_va and the
959 silc_command_payload_encode_va to support that if argument is
960 NULL it ignores and checks the next argument. Affected file
961 lib/silccore/silccommand.c.
963 * Added silc_server_send_notify_ban to send the BAN notify
964 type between routers.
966 * Chaned the silc_notify_payload_encode to support that if
967 argument is NULL it ignores and checks the next argument.
968 Affected file lib/silccore/silcnotify.c.
970 * Tested ban lists in router environment successfully.
972 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
974 * Implemented BAN command to the server, in silcd/command.[ch].
976 * Removed the BAN and INVITE_LIST modes from the CMODE command
979 * Added function silc_string_match to regex match two strings.
980 Affected files lib/silcutil/silcutil.[ch].
982 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
984 * Redefined parts of the SilcChannelEntry in the server to support
985 the new ban and invite lists.
987 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
989 * Redefined the INVITE command. The same command can be used to
990 invite individuals to the channel but also to manage the invite
991 list of the channel (to add to and remove from the invite list).
992 Updated the protocol specs.
994 * Added new command SILC_COMMAND_BAN that can be used to manage
995 the ban list of the channel. Updated the protocol specs.
997 * Removed the channel modes: the SILC_CMODE_BAN and the
998 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
999 in the CMODE command. The equivalent features are now available
1000 using INVITE and BAN commands. Updated the protocol specs.
1002 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1003 in the network about change in the current ban list. The notify
1004 type is not used by the client.
1006 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1007 support the invite lists.
1009 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1011 * Added new function silc_string_regexify that converts string
1012 including wildcard characters into regex string that can
1013 be used by the GNU regex library. Added into the file
1014 lib/silcutil/silcutil.[ch].
1016 Added silc_string_regex_combine to combine to regex strings
1017 into one so that they can be used as one regex string by
1018 the GNU regex library. Added into the file
1019 lib/silcutil/silcutil.[ch].
1021 Added silc_string_regex_match to match two strings. It returns
1022 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1024 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1026 * Imported GNU regex to the soruce tree into lib/contrib.
1027 Fixed some compiler warning from the regex.c.
1029 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * Fixed MOTD command in the server to work in router environment.
1033 * Fixed the MOTD command in the client library to support
1034 the server argument in the command.
1036 * Added `nickname_len' argument to the silc_idlist_add_client
1037 in the server, as the `nickname' argument may be binary data
1040 * Added silc_idlist_get_channels to return all channels from
1043 * Implemented LIST command to the server. Affected file is
1046 * Implemented the LIST command to the client library and on the
1049 * Added [<user count>] argument to the LIST command reply.
1050 With private channels the user count is not shown.
1052 * Updated TODO and README.
1054 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1056 * The client entry's data.registered must be TRUE even with
1057 global client entry on global client list. The data.registered
1058 is used to check whether the client is anymore in the network,
1059 for example with WHOWAS command so it must be valid.
1061 * Fixed the WHOWAS command in the server. It now actually works
1062 in router environment. Added function into silcd/command_reply.c
1063 silc_server_command_reply_whowas_save.
1065 * Added silc_idlist_purge function to the silcd/idlist.c
1066 to periodically purge the ID Cache.

1069 environment. Added <server name> argument to the INFO command
1070 reply. Updated the protocol specs.
1072 * Fixed minor bug in silc_idcache_purge to not purge if the
1073 expire value is zero.
1075 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1076 they were buggy because of the WHOWAS information.
1078 * Fixed local command MSG to handle the async resolving of
1079 the remote client properly. It used to fail the first MSG.
1080 Affected file silc/local_command.c.
1082 * Added `data_len' field to SilcIDCache context.
1084 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1086 * Update TODO. Todo in commands in the server.
1088 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1090 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1091 used by routers as broadcast packet to inform other routers
1092 about the changed user mode.
1094 Implemented the notify handling in the server. Affected file is
1095 silcd/packet_receive.c. Added the function
1096 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1098 * Added new generic Channel Payload and deprecated the New Channel
1099 Payload. The New Channel Payload is now the generic Channel
1102 * Added new argument `mode' to the silc_server_send_new_channel
1103 as it is required in the Channel Payload now.
1105 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1106 and created a new and real SilChannelPayload to represent the
1107 new generic Channel Payload. Implemented the encode/decode
1108 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1110 * Added silc_server_get_client_channel_list to return the list
1111 of channels the client has joined for WHOIS command reply.
1112 Affected file silcd/server.[ch].
1114 * Implemented the channel list sending in the WHOIS command reply
1115 in server and in the client.
1117 Implemented the channel list displaying on the user interface
1118 as well. Affected file silc/client_ops.c.
1120 * Added silc_channel_payload_parse_list to parse list of Channel
1121 Payloads. It returns SilcDList list of SilcChannelPayloads.
1122 Client for example can use this function to parse the list of
1123 channels it receives in the WHOIS command reply. The caller
1124 must free the list by calling silc_channel_payload_list_free.
1125 Affected files lib/silccore/silcchannel.[ch].
1127 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1129 * Added one new argument <user mode> to the WHOIS command reply
1130 to return the mode of the user in SILC. Updated the protocol
1133 Implemented it to the server and client.
1135 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Fixed the mode printing on the user interface on joining.
1138 Affected file silc/client_ops.c.
1140 * Implemented the UMODE command and user modes in general to the
1141 client library and to the user interface.
1143 * Implemented the UMODE command to the server.
1145 * The server now sends UNKNOWN_COMMAND error status if client sends
1146 unknown command. Affected file silcd/command.c.
1148 * All server commands now handle the command identifier the right
1149 way when sending the command reply to the client. The client can
1150 use to identify the command replies with the identifier.
1152 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Added silc_server_get_client_route to resolve the route to
1155 the client indicated by the client ID. Affected file is
1158 * Added silc_server_relay_packet as general function to relay
1159 packet to arbitrary destination. This deprecates functions
1160 like _send_private_message_key, _relay_notify etc. Affected
1161 file is silcd/packet_send.[ch].
1163 Removed silc_server_send_key_agreement,
1164 silc_server_send_private_message_key and
1165 silc_server_packet_relay_notify functions from the file
1166 silcd/packet_send.[ch].
1170 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1171 server. Affected file silcd/packet_receive.[ch].
1173 * Implemented the KILL command to the client. Implemented the
1174 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1175 Affected files lib/silcclient/command[_reply].c and
1176 lib/silcclient/client_notify.c. Implemented the KILL notify
1177 printing in the user inteface.
1179 * Fixed a lot silc_parse_nick memory leaks from the client
1180 library in the file lib/silcclient/command.c.
1182 * Changed the silc_server_send_notify_on_channels's `sender'
1183 argument from SilcSocketConnection to SilcClientEntry to
1184 check the sender as entry and not as connection object and not
1185 to send to the client provided as argument. The affected file
1186 is silcd/packet_send.[ch].
1188 * The notify packets that are destined directly to the client used
1189 to not to be processed by the server. Now changed that and the
1190 server processes all notify packets. After relaying the packet
1191 to the client the notify packet is processed in the server.
1193 * The silc_server_free_client_data now checks whether there is
1194 pending outgoing traffic for the client and purges the data to
1195 the network before removing the client entry.
1197 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1199 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1200 an client is killed from the SILC Network. Updated the protocol
1203 Added new function silc_server_send_notify_killed to the
1204 silcd/packet_send.[ch].
1206 * Added function silc_server_packet_relay_notify to relay notify
1207 packets that are destined directly to a client. In this case
1208 the server does not process the notify packets but merely relays
1209 it to the client. Affected file silcd/packet_send.[ch].
1211 Added also silc_server_packet_process_relay_notify to check
1212 whereto relay the notify. Affected file is
1213 silcd/packet_receive.[ch].
1215 * Implemented the KILL command to the server.
1219 * Added the backup schema desgined last fall to the protocol
1220 specs for everyone to see. The specification is in the
1221 *-spec-xx.txt draft and the packet type definitions for the
1222 backup routers is in *-pp-xx.txt draft. Thusly, added also
1223 new packet type SILC_PACKET_CELL_ROUTERS.
1225 * A big security problem in the implementation discovered. The
1226 signoff of an client did not cause new channel key generation
1227 which it of course should've done. The channel keys must be
1228 always re-generated when client leaves (or signoffs) the channel.
1229 The silc_server_remove_from_channels funtion now handles
1230 the channel key re-generation.
1232 * Added `sender' argument to the silc_server_send_notify_on_channels
1233 to not to send the client provided as argument. Affected file
1234 silcd/packet_send.[ch].
1236 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1238 * Implemented OPER and SILCOPER commands into the server and
1241 * Added silc_auth_verify and silc_auth_verify_data to verify
1242 the authentication directly from the authentication payload.
1243 It supports verifying both passphrase and public key based
1244 authentication. Affected file lib/silccore/silcauth.[ch].
1246 * Added `hash' field to the SilcIDListData structure. It is the
1247 hash negotiated in the SKE protocol. Affected file is
1250 * Slight redesigning of the SilcAuthPayload handling routines.
1251 Do not send SilcPKCS but SilcPublicKey as argument.
1253 * Implemented the public key authentication support to the
1254 serverconfig. The public key is loaded from the provided path
1255 and saved as authentication data to void * pointer. Thus,
1256 changed the unsigned char *auth_data to void *auth_data;
1258 * Fixed SHUTDOWN command to send the reply before the server
1259 is shutdown. :) Affected file silcd/command.c.
1261 * Fixed fatal bug in CONNECT command. The hostname was invalid
1262 memory and server crashed. Affected file silcd/command.c.
1264 * Fixed fatal bug in CLOSE command. The server_entry became
1265 invalid but was referenced later in the command. Affected file
1268 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1270 * Fixed fatal bug in failure packet handling. Server ignored
1271 the failure and thus crashed when it came.
1275 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1277 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1278 that the command may be executed only once in (about) 2 seconds.
1279 The old SILC_CF_LAG flag is same but allows command bursts up
1280 to five before limiting.
1282 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1283 server code. Various commands now includes the CF_LAG_STRICT
1284 flag to disallow any kind of miss-use of the command.
1286 * Fixed the silc_buffer_unformat to not to allocate any data
1287 if the length of the data is zero. It used to allocate the
1288 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1290 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1292 * Changed the format of AdminConnection configuration section
1293 in the server. Added username of the admin to the format.
1294 Affected files silcd/serverconfig.[ch].
1296 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1297 to return admin configuration data by host, username and/or
1300 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1302 * Implemented WHOWAS command to the server. Added the functions:
1304 silc_server_command_whowas_parse,
1305 silc_server_command_whowas_send_reply,
1306 silc_server_command_whowas_from_client and
1307 silc_server_command_whowas_from_server
1309 * Added <Client ID> argument to the WHOWAS command reply. Updated
1310 the protocol specs accordingly.
1312 * Implemented WHOWAS command and command_reply to the client
1315 Implemented the WHOWAS printing on the user interface.
1317 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1319 * Added new argument to the WHOWAS command reply, the real name.
1320 It is an optional argument. Updated the protocol specs.
1322 * Added SilcIDCacheDestructor callback that is registered when
1323 the SilcIDCache is allocated. The callback is called when
1324 an cache entry in the ID Cache expires, or is purged from the
1325 cache. Added into lib/silccore/idcache.[ch].
1327 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1328 to destruct the client entries when the cache entry expires.
1329 Other ID Cache's in server and in the client library ignores
1332 * If the ID Cache entry's `expire' field is zero then the entry
1333 never expires. Added boolean `expire' argument to the
1334 silc_idcache_add function in the lib/silccore/idcache.[ch].
1335 If it is TRUE the default expiry value is used.
1337 * Added silc_server_free_client_data_timeout that is registered
1338 when client disconnects. By default for 5 minutes we preserve
1339 the client entry for history - for WHOWAS command.
1341 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1343 * Added support to the server to enforce that commands are not
1344 executed more than once in 2 seconds. If server receives
1345 commands from client more frequently, timeout is registered
1346 to process the commands. Affected file silcd/command.c.
1347 Added new function silc_server_command_process_timeout.
1349 * Changed NICK_NOTIFY handling in client library to check that
1350 if the client's nickname was changed, so there is no need to
1351 resolve anything from the server.
1353 * Removed error printing from the WHOIS and IDENTIFY commands.
1354 If error occurs then it is ignored silently in the client library.
1355 The application, however, may map the received error to
1356 human readable error string. The application currently maps
1357 the NO_SUCH_NICKNAME error to string.
1359 * Made the command status message public to the application. Moved
1360 them from lib/silcclient/command_reply.c to
1361 lib/silcclient/command_reply.h. The application can map the
1362 received command status to the string with the
1363 silc_client_command_status_message function.
1365 * Added check to the server to check that client's ID is same
1366 as the Source ID in the packet the client sent. They must
1369 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1371 * Added dist-bzip hook to the Makefile.am to make bzip2
1372 compressed distributions.
1374 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1376 * Server now enforces the maximum length for the nickname and
1377 the channel as protocol specification dictates. 128 bytes for
1378 nickname and 256 bytes for channel name.
1380 * Moved the WHOIS printing to the application. The client libary
1381 does not print out the WHOIS information anymore, the application
1382 must do it. Renamed silc_client_command_reply_whois_print to
1383 the silc_client_command_reply_whois_save.
1385 The client's idle time is also sent to the application now, and
1386 the idle is shown on screen.
1388 * Added silc_client_command_reply_identify_save to save the
1389 received IDENTIFY entries.
1391 * Do not check for channel private keys in message sending and
1392 reception if the channel does not have the PRIVKEY mode set.
1393 Affected file lib/silclient/client_channel.c.
1395 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1398 just surfaced after chaning the JOIN procedure.
1400 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Added silc_client_get_clients_by_list to get client entries
1403 from Client ID list, that is returned for example by JOIN
1404 and USERS command replies. The application should use this
1405 function for example when JOIN command reply is received to
1406 resolve the clients already on the channel (library does not
1407 do that anymore as USERS command reply is not used in the JOIN
1408 procedure anymore). Affected files lib/silcclient/silcapi.h and
1409 lib/silcclient/idlist.c.
1411 * JOIN command reply and USERS command reply returns now SilcBuffer
1412 pointers instead of unsigned char pointers when returning
1413 the client list and mode list.
1415 * Added <Client ID> argument to the JOIN command reply, mainly
1416 for the server to identify for which client the command was
1417 originally sent. Updated protocol specs accordingly.
1419 * Added SilcDlist private_key pointer to the SilcChannelEntry
1420 in the client to support the channel private keys. Affected
1421 file is lib/silcclient/idlist.h.
1423 * Added SilcChannelPrivateKey argument to the function
1424 silc_client_send_channel_message so that application can choose
1425 to use specific private ke if it wants to. If it is not provided,
1426 the normal channel key is used, unless private keys are set.
1427 In this case the first (key that was added first) is used
1428 as the encryption key.
1430 * Implemented the support for channel private key handling.
1431 Implemented the following functions:
1433 silc_client_add_channel_private_key,
1434 silc_client_del_channel_private_keys,
1435 silc_client_del_channel_private_key,
1436 silc_client_list_channel_private_keys and
1437 silc_client_free_channel_private_keys
1439 Affected file lib/silcclient/client_channel.c.
1441 * Added the support for the private keys in the channel message
1442 sending and encryption and in the message reception and
1443 decryption. Affected funtions are
1444 silc_client_send_channel_message and silc_client_channel_message.
1446 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1448 * Added SKE's key verify callback to the client library's
1449 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1451 * Removed the statement that server (or router) must send USERS
1452 command reply when joining to the channel so that the client
1453 knows who are on the channel. Instead, the client list and
1454 client's mode list is now sent in the JOIN command reply to the
1455 client who joined channel. This is better solution.
1457 * Added function silc_server_get_users_on_channel and function
1458 silc_server_save_users_on_channel to the silcd/server.[ch].
1460 * Removed function silc_server_command_send_users from the
1463 * Do not show topic on the client library anymore. The topic is
1464 sent in the command reply notify to the application and the
1465 application must show the topic now.
1467 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1469 * Added client searching by nickname hash into the IDENTIFY and
1470 WHOIS commands in the server as they were clearly missing from
1471 them. Affected file is silcd/command.c.
1473 * Fixed a bug in private message receiving in the client library.
1474 The remote ID was freed and it wasn't supposed, now it is
1477 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1479 * Minor fix to the channel payload; allocate the data area, as it
1480 needs to be of specific length.
1482 * If the key agreement port is zero then the operating
1483 system will define the bound port. Affected files are
1484 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1486 * Added new function silc_channel_payload_decrypt into the file
1487 lib/silccore/silcchannel.[ch].
1489 * Moved the channel message etc, check from silc_packet_decrypt
1490 to applications. The library calls now a generic
1491 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1492 when the packet is either normal or special. This was done to
1493 allow more wide range of checking that was not allowed when
1494 the code was in library. Now applications can do virtually any
1495 checks to the packet and return to the library the decision how
1496 the packet should be processed. Affected files are
1497 lib/silccore/silcpacket.[ch].
1499 Added silc_server_packet_decrypt_check to the server and
1500 silc_client_packet_decrypt_check to the client library.
1502 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1503 to send with specified source and destination information.
1505 * Channel message delivery between routers was broken after the
1506 channel key distribution was fixed earlier. The channel key
1507 was used be to distributed to other routers as well which is not
1508 allowed by the protocol. Now this is fixed and channel keys
1509 really are cell specific and the channel message delivery between
1510 routers comply with the protocol specification.
1512 * Fixed various commands in server to check also the global list
1513 for the channel entry and not just the local list. The affected
1514 file silcd/command.c.
1516 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1518 * Added assert()s to buffer formatting and unformatting routines
1519 to assert (if --enable-debug) when error occurs. Affected
1520 file: lib/silcutil/silcbuffmt.c.
1522 * Changed to auto-reconnect to check whether the remote host is
1523 router and register the re-connect timeout if it is. It used
1524 to check that whether we are normal server, but router must do
1525 auto-reconnect with another router as well. Affected file
1528 * Removed the [<key len>] option from CMODE command as the cipher
1529 name decides the key length, nowadays. See the defined ciphers
1530 from the protocol specification.
1532 * Added [<hmac>] option to the CMODE command to define the HMAC
1533 for the channel. Added SILC_CMODE_HMAC channel mode.
1535 * Added [<hmac>] option for the JOIN command so that user can
1536 select which HMAC is used to compute the MACs of the channel
1539 * Added Hmac field to the Channel Message Payload. The integrity
1540 of plaintext channel messages are now protected by computing
1541 MAC of the message and attaching the MAC to the payload. The
1542 MAC is encrypted. Now, it is clear that this causes some
1543 overhead to the size of the packet but rationale for this is that
1544 now the receiver can verify whether the channel message decrypted
1545 correctly and also when private keys are set for the channel the
1546 receiver can decrypt the packet with several keys and check from
1547 the MAC which key decrypted the message correctly.
1549 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1550 lib/silccrypt/silccipher.[ch].
1552 * Added silc_hash_len to return the digest length into the
1553 lib/silcrypt/silchash.[ch].
1555 * Rewrote parts of Silc Channel Payload interface in the
1556 lib/silccore/silcchannel.[ch]. The encode function now also
1557 encrypts the packet and parse function decrypts it.
1559 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1561 * Fixed a minor formatting bug in the SKE's key material processing.
1562 It actually might have processed the keys wrong way resulting
1565 * Redefined the mandatory HMAC algorithms and added new algorithms.
1566 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1567 and hmac-md5 truncated to 96 bits. The mandatory is now
1568 hmac-sha1-96. Rest are optional (including the one that used
1569 to be mandatory). Rationale for this is that the truncated HMAC
1570 length is sufficient from security point of view and can actually
1571 make the attack against the HMAC harder. Also, the truncated
1572 HMAC causes less overhead to the packets. See the RFC2104 for
1575 * Added new [hmac] configuration section. The SKE used to use
1576 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1577 is of course wrong. The official names that must be proposed in
1578 the SKE are the ones defined in the protocol specification
1579 (hmac-sha1-96 for example). The user can configure any hmac
1580 using any hash function configured in the [hash] section. At
1581 least, the mandatory must be configured.
1583 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1585 * Added HMAC list to the SKE proposal list. It has now both
1586 hash algorithm list and HMAC list. This makes the protocol
1587 incompatible with previous versions. The SKE now seems to work
1588 the way it is supposed to work, for the first time actually.
1590 * Defined plain Hash algorithms to the protocol specification.
1593 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Implemented support for key agreement packets into the server.
1596 Added functions silc_server_key_agreement and
1597 silc_server_send_key_agreement. Other than these functions,
1598 server has nothing to do with this packet.
1600 * Added support for private message key packets into the server.
1601 Added functions silc_server_private_message_key and
1602 silc_server_send_private_message_key.
1606 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1607 called in the protocol's final callback instead in the END
1608 protocol state. This makes a little more sense and in the same
1609 time in client we can use the same protocol routines for normal
1610 key exchange and to key agreement packet handling as well.
1612 * Added to both client's and server's KE protocol context the
1613 SilcSKEKeyMaterial pointer to save the key material. We will
1614 bring the key material to the protocol's final callback by doing
1615 this. The final callback must free the key material.
1617 * Added SKE's packet_send callback into client's KE protocol
1618 context so that the caller can choose what packet sending function
1619 is used. This way we can use different packet sending when
1620 doing normal SKE when doing key agreement packet handling (in
1621 the key agreement packet handling we do not want to encrypt
1624 * Implemented the responder side of the key agreement routines
1625 in the client. The client can now bind to specified port and
1626 accept incoming key negotiation. The key material is passed
1627 to the application after the protocol is over.
1629 * Implemented the processing of incoming Key Agreement packet
1630 in the client. Added function silc_client_key_agreement to
1633 * Implemented the intiator side of the key agreement routines
1634 in the client. The client can now initiate key agreement with
1635 another remote client. The key material is passed to the
1636 application after the protocol is over.
1638 * Created client_keyagr.c to include all the key agreement
1641 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1642 SILC_TASK_CALLBACK except that it is not static.
1644 * Created client_notify.c and moved the Notify packet handling
1645 from the client.[ch] into that file.
1647 * Created client_prvmsg.c and moved all private message and
1648 private message key routines from the client.[ch] into that file.
1650 * Create client_channel.c and moved all channel message and
1651 channel private key routines from the client.[ch] into that file.
1653 * Changed silc_client_get_client_by_id_resolve to resolve with
1654 WHOIS command instead of IDENTIFY command, in the file
1655 lib/silclient/idlist.c.
1657 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1659 * Implemented the SKE's responder side to the Client library.
1661 * When FAILURE is received to the protocol do not trust it
1662 blindly. Register a timeout to wait whether the remote closes
1663 the connection as it should do it, only after that process the
1664 actual failure. This was changed to both client and server.
1666 * Added client_internal.h to include some of the structures
1667 there instead of client.h in lib/silcclient/.
1669 * Added function silc_task_unregister_by_callback to unregister
1670 timeouts by the callback function.
1672 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1674 * Some "Incomplete WHOIS info" errors has been appearing on the
1675 log files. Took away the entry->userinfo check from WHOIS
1676 reply sending. The entry->userinfo is now " " if client did not
1677 provide one. I thought this was fixed earlier but something
1678 is wrong still. Let's see if the error still appears.
1680 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1682 * Fixed a minor bug in the login when the channel key is
1683 re-generated in the server. It used to generate the key in
1684 wrong order and thus caused problems in the channel traffic.
1686 * Fixed a minor bug in channel key distsribution after
1687 KICK command. The key was not sent to the router even though
1690 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1692 * Added silc_ske_process_key_material_data as generic routine
1693 to process any key material as the SILC protocol dictates. The
1694 function is used by the actual SKE library but can be used by
1695 applications as well. This relates to the private message keys
1696 and the channel private keys since they must be processed the
1697 same way the normal SILC session keys. The protocol dictates
1698 this. Affected files: lib/silcske/silcske.[ch].
1700 Added also silc_ske_free_key_material to free the
1701 SilcSKEKeyMaterial structure.
1703 * Defined silc_cipher_set_key function to set the key for
1704 cipher without using the object's method function. The affected
1705 files: lib/silccrypt/silccipher.[ch].
1707 * Implemented silc silc_client_add_private_message_key,
1708 silc_client_add_private_message_key_ske,
1709 silc_client_del_private_message_key,
1710 silc_client_list_private_message_keys and
1711 silc_client_free_private_message_keys functions in the
1714 Added functions silc_client_send_private_message_key to send
1715 the Private Message Key payload and silc_client_private_message_key
1716 to handle incoming Private Message Key payload.
1718 * Added Cipher field to the Private Message Key payload to set
1719 the cipher to be used. If ignored, the default cipher defined
1720 in the SILC protocol (aes-256-cbc) is used.
1722 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1724 * Removed lib/silcclient/ops.h file.
1726 Redefined parts of the SILC Client Library API. Created new
1727 file silcapi.h that deprecates the ops.h file and defines the
1728 published Client Library API. Defined also private message key
1729 API and channel private key API into the file.
1731 This is the file that the application must include from the
1732 SILC Client Library. Other files need not be included by
1733 the application anymore.
1735 * Added new key_agreement client operation callback and also
1736 defined the Key Agreement library API for the application.
1738 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1740 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1741 is used by clients to request key negotiation between another
1742 client in the SILC network. If the negotiation is started it
1743 is performed using the SKE protocol. The result of the
1744 negotiation, the secret key material, can be used for example
1745 as private message key.
1747 Implemented the Key Agreement payload into the files
1748 lib/silccore/silauth.[ch].
1750 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1752 * Redefined ciphers for the SILC protocol. Added some new ciphers
1753 and defined the key lengths for the algorithms. Changed the
1754 code accordingly. The default key length is now 256 bits.
1756 * Fixed SKE key distribution function silc_ske_process_key_material
1757 when the key length is more than 128 bits. The default key
1758 length in SILC is now 256 bits.
1760 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1761 to indicate unsupported algorithm.
1763 * Renamed rijndael.c to aes.c and all functions as well.
1765 * Fixed a long standing channel key setting bug in client library.
1766 Weird that it has never surfaced before.
1768 * Fixed bug in channel deletion. If the entire channel is removed
1769 then it must also delete the references of the channel entry
1770 from the client's channel list as the client's channel entry and
1771 the channel's client entry share same memory.
1773 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1775 * Implemented CONNECT and SHUTDOWN commands in the client.
1777 * Implemented CLOSE command to the client.
1779 * Added the function silc_idlist_find_server_by_name into the
1780 files silcd/idlist.[ch].
1782 Added the function silc_idlist_find_server_by_conn into the
1783 files silcd/idlist.[ch].
1785 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1787 * DIE command was renamed to SHUTDOWN. Updated the both code
1790 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1791 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1793 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1796 * Added function silc_server_create_connection function to create
1797 connection to remote router. My server implementation actually
1798 does not allow router to connect to normal server (it expects
1799 that normal server always initiates the connection to the router)
1800 so the CONNECT command is only good for connecting to another
1803 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1806 or some other client was kicked from the channel.
1808 Implemented the handling of the notify type to both client
1811 Implemented silc_server_send_notify_kicked to send the KICKED
1812 notify. It is used to send it to the server's primary router.
1814 * Implemented the KICK command into server and client.
1816 * Added `query' argument to the silc_idlist_get_client function
1817 to indicate whether to query the client from server or not if
1820 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1821 to indicate that the client is not channel founder.
1825 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1827 * Removed the rng context from SilcPacketContext structure and
1828 changed that the packet routine uses the Global RNG API.
1830 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1832 * Added support for quit message that client can "leave" on the
1833 channel when it quits the SILC. It is ditributed inside the
1834 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1836 Added silc_server_free_client_data that will take the
1837 signoff message as argument.
1839 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1841 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1843 * Updated parts of the protocol specification to keep it up
1846 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1848 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1849 payloads in one packet.
1851 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1852 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1853 use now the new List flag.
1855 * Also deprecated the following packet types: REPLACE_ID,
1856 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1858 * Added list support for Notify packet in server.
1860 * Added silc_server_send_notify_channel_change to send the
1861 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1862 the silc_server_send_replace_id.
1864 * Added silc_server_send_notify_nick_change to send the
1865 NICK_CHANGE notify type. Deprecates the function
1866 silc_server_send_replace_id.
1868 * Added silc_server_send_notify_join to send the JOIN notify type.
1869 Deprecates the function silc_server_send_new_channel_user.
1871 * Added silc_server_send_notify_leave to send LEAVE notify type.
1872 Deprecates the function silc_server_send_remove_channel_user.
1874 * Added silc_server_send_notify_cmode and
1875 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1876 types. Deprecates the silc_server_send_set_mode function.
1878 * Added SERVER_SIGNOFF notify type to indicate that server has
1879 quit. This means that all clients on the channel from that
1880 server will drop. This can be also used when netsplit happens.
1882 Deprecated REMOVE_ID packet type since it is not needed anymore
1885 Added silc_server_send_notify_server_signoff to send the
1886 SERVER_SIGNOFF notify type. Deprecates the function
1887 silc_server_send_remove_id.
1889 Added also silc_server_send_notify_signoff to send the
1890 SIGNOFF notify type.
1892 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1893 SILC protocol from this day on. Changed the protocol
1894 specification as well.
1896 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1897 notify type. It is used between routers to notify about
1898 topic changes on a channel.
1900 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1903 * Partly updated the protocol specification to comply with the
1904 changes now made. It is still though a bit outdated.
1906 * The JOIN notify type now takes one extra argument <Channel ID>.
1907 The packet used to be destined to the channel but now the
1908 JOIN type may be sent as list thus it is impossible to
1909 destine it to any specific channel. By adding this argument
1910 it is again possible.
1912 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1914 * Added CREDITS file. The CHANGES and CREDITS file will appear
1915 in the distribution as well.
1917 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1919 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1920 types in the server's silcd/packet_receive.c.
1922 * Implemented CMODE and CUMODE to work in router environment.
1924 * Fixed minor encoding and decoding buglet from the
1925 lib/silccore/silcmode.c.
1927 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1930 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1932 * Changed all SilcConfigServer* and silc_config_server* to
1933 SilcServerConfig* and silc_server_config*, respectively.
1936 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1938 * Associated the ID (client or server ID) to the Authentication
1939 Payload to avoid any possibility of forging. Updated the
1940 protocol specification and the code accordingly.
1942 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1944 * The RSA key length is now save to the RsaKey context in the
1945 key generation process in lib/silccrypt/rsa.c. The key length
1946 is now used to figure out the maximum size of the block allowed
1947 to be encrypted/signed.
1949 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1950 is equivalent to the silc_mp_mp2bin but does not allocate any
1953 * Changed silc_mp_mp2bin API to take length argument. If it is
1954 non-zero then the buffer is allocated that large. If zero, then
1955 the size is approximated using silc_mp_sizeinbase, which however
1958 * Created Global RNG API which is global RNG that application can
1959 initialize. After initializing, any routine anywhere in the
1960 code (including library) can use RNG without allocating a new
1961 RNG object. This was done to allow this sort of use of the
1962 RNG in code that has no chance to allocate RNG object. All
1963 applications currently allocate this and many routines in the
1964 library use this. Affected file lib/silccrypt/silcrng.[ch].
1966 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1967 it to use the Global RNG API.
1969 * Defined Authentication Payload into protocol specification that
1970 is used during SILC session to authenticate entities. It is
1971 used for example by client to authenticate itself to the server
1972 to obtain server operator privileges.
1974 Implemented this payload into the lib/silccore/silcauth.[ch].
1975 Implemented also routines for public key based authentication
1976 as the new protocol specification dictates.
1978 Moved definitions of different authentication methods from
1979 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1981 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1982 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1983 silc_pkcs_verify_with_hash functions into the file
1984 lib/silccrypt/silcpkcs.[ch].
1986 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * The client entry's userinfo pointer must be always valid.
1989 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1990 will fail since it requires the userinfo. Now, the userinfo
1991 is allocated as "" if actual userinfo does not exist. Actually,
1992 it must exist and it is totally Ok to drop client connections
1993 that does not announce the userinfo. However, we will make
1994 this workaround for now.
1996 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1997 to return the remote port by socket.
1999 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2001 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2002 SILC_SERVER_PENDING_EXEC and added an new macro
2003 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2004 data or when error occurs while processing the pending command.
2006 Added new argument `destructor' into silc_server_command_pending
2007 and to the SilcServerCommandPending object. This destructor is
2008 now called after calling the pending callback or if error occurs
2009 immediately. If error occurs the actual pending callback won't
2010 be called at all - only the destructor. The destructor may be
2011 NULL if destructor is not needed.
2013 All this applies for client library code as well. Similar
2014 changes were made there as well for the pending commands.
2016 In the client, the application must now allocate the
2017 SilcClientCommandContext with the silc_client_command_alloc
2020 * Added reference counter to the SilcServerCommandContext. Added
2021 function silc_server_command_alloc and silc_server_command_dup
2024 Same type of functions added to the client library for the same
2027 * Removed the cmd_ident from IDListData away since it is now
2028 global for all connections. It is the command identifier used
2029 in command sending and with pending commands. The affected file
2032 * Added reference counter to the SilcSocketConnection objecet to
2033 indicate the usage count of the object. The object won't be
2034 freed untill the reference counter hits zero. Currently only
2035 server uses this, and client ignores it. The client must be
2036 set to use this too later. The affected files are
2037 lib/silccore/silcsockconn.[ch]. Added also the function
2038 silc_socket_dup to increase the reference counter.
2040 This was mainly added because it is possible that the socket
2041 is removed underneath of pending command or other async
2042 operation. Now it won't be free'd and proper DISCONNECTING
2043 flags, etc. can be set to avoid sending data to connection that
2044 is not valid anymore.
2046 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2047 the connection. After that it sets SILC_SET_DISCONNECTED.
2048 It is, however, possible that the socket data is not still freed.
2049 The silc_server_packet_process now checks that data is not
2050 read or written to connection that is DISCONNECTED. The socket
2051 get's freed when the reference counter hits zero.
2053 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2055 * Changed the client operation API: channel_message operation's
2056 `sender' is now the client entry of the sender, not the nickname
2057 and the `channel' is the channel entry, not the channel name.
2059 In the private_message operation the `sender' is now also the
2060 client entry of the sender not the nickname.
2062 Affected file is lib/silcclient/ops.h and all applications
2063 using the client operations.
2065 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2067 * Moved the calling of ops->connect() from connect_to_server_final
2068 into receive_new_id functin since that is the point when the
2069 client is actually allowed to send traffic to network. The
2070 affected file is lib/silcclient/client.c.
2072 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2074 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2075 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2076 (if needs broadcasting) instead of broadcasting the packets one
2077 by one which would make a burst in the network traffic.
2079 * Added `broadcast' argument to the functions in silcd/server.[ch]
2080 silc_server_create_new_channel[_with_id] to indicate whether
2081 to send New Channel packet to primary router.
2083 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * Added new function into the silcd/server.[ch] files:
2086 silc_server_create_new_channel_with_id to create new channel with
2087 already existing Channel ID.
2089 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2090 lib/silccore/silcpacket.h. This packet is used t send list of
2091 Set Mode payloads inside one packet. Server uses this to set
2092 the modes for the channels and clients on those channels, that it
2093 announced to the router when it connected to it. The protocol
2094 specification has been updated accordingly.
2096 * The silc_server_new_channel did not handle the packet coming
2097 from normal server as it normally does not send that. However,
2098 when it announces its channels it does send it. Implemented
2099 the support for that.
2101 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2102 into the file lib/silccore/id.h.
2104 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2106 * Fixed memory leaks in the functions silc_idlist_del_client,
2107 silc_idlist_del_channel and silc_idlist_del_server in the file
2108 silcd/idlist.c. All of those leaked like a sieve.
2110 * Fixed some small memory leaks in the client's function
2111 silc_client_notify_by_server.
2113 * Added functions into silcd/server.c: silc_server_announce_clients,
2114 silc_server_announce_channels and silc_server_announce_server.
2115 These functions are used by normal and router server to announce
2116 to its primary router about clients, channels and servers (when
2117 router) that we own. This is done after we've connected to the
2120 These functions effectively implements the following packet types:
2121 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2122 and SILC_PACKET_NEW_ID_LIST.
2124 * Added new functions into the silcd/packet_receive.[ch]:
2125 silc_server_new_id_list, silc_server_new_channel_list and
2126 silc_server_new_channel_user_list to handle the incoming
2127 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2129 * Added support of changing Channel ID in the function
2130 silc_server_replace_id. If the server that announces a channel
2131 to the router already exists in the router (with same name but
2132 with different Channel ID), router is responsible to send
2133 Replace ID packet to the server and force the server to change
2134 the Channel ID to the one router has.
2136 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2137 client that the Channel ID has been changed by the router. The
2138 normal server sends this to the client. Client must start using
2139 the new Channel ID as the channel's ID.
2141 Implemented handling of this new type into lib/silcclient/client.c
2142 into the function silc_client_notify_by_server.
2144 * Added new function silc_idlist_replace_channel_id into the files
2145 silcd/idlist.[ch] to replace the Channel ID.
2147 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2149 * Call silc_server_command_identify_check always when processing
2150 the IDENTIFY command in silcd/command.c
2152 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2154 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2155 send keepalive packets. The packet can be sent by clients,
2156 servers and routers.
2158 Added function silc_socket_set_heartbeat into the file
2159 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2160 If not set, the heartbeat is not performed. The actual
2161 heartbeat is implemented in the low level socket connection
2162 library. However, application is responsible of actually
2165 Added silc_server_send_heartbeat to send the actual heartbeat
2166 packet into silcd/packet_send.[ch]. Server now performs
2167 keepalive with all connections.
2169 * Added silc_task_get_first function into lib/silcutil/silctask.c
2170 to return the timeout task with shortest timeout. There was a bug
2171 in task unregistration that caused problems. TODO has been
2172 updated to include that task system must be rewritten.
2174 * The client library will now resolve the client information when
2175 receiving JOIN notify from server for client that we know but
2176 have incomplete information.
2178 * Rewrote parts of silc_server_remove_from_channels and
2179 silc_server_remove_from_one_channel as they did not remove the
2180 channel in some circumstances even though they should've.
2182 * Encryption problem encountered in server:
2184 The LEAVE command used to send the Channel Key packet to the
2185 router immediately after generating it. However, the code
2186 had earlier sent Remove Channel user packet but not immediately,
2187 ie. it was put to queue. The order of packets in the router
2188 was that Channel Key packet was first and Remove Channel User
2189 packet was second, even though they were encrypted in the
2190 reverse order. For this reason, MAC check failed. Now, this
2191 is fixed by not sending the Channel Key packet immediately but
2192 putting it to queue. However, this is more fundamental problem:
2193 packets that are in queue should actually not be encrypted
2194 because packets that are sent immediately gets encrypted
2195 actually with wrong IV (and thus MAC check fails). So, packets
2196 that are in queue should be encrypted when they are sent to
2197 the wire and not when they put to the queue.
2199 However, the problem is that the current system has not been
2200 designed to work that way. Instead, the packet is encrypted
2201 as soon as possible and left to the queue. The queue is then
2202 just purged into wire. There won't be any fixes for this
2203 any time soon. So, the current semantic for packet sending
2206 o If you send packet to remote host and do not force the send
2207 (the packet will be in queue) then all subsequent packets to the
2208 same remote host must also be put to the queue. Only after the
2209 queue has been purged is it safe again to force the packet
2212 o If you send all packets immediately then it safe to send
2213 any of subsequent packets through the queue, however, after
2214 the first packet is put to queue then any subsequent packets
2215 must also be put to the queue.
2217 Follow these rules and everything works fine.
2219 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2221 * Added new function silc_server_remove_clients_by_server to
2222 remove all client entries from ID list when the server connection
2223 is lost. In this case it is also important to invalidate all
2224 client entires as they hold the invalid server entry. This
2225 fixes fatal bug when server has lost connection and will reconnect
2228 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2230 * Made some sanity checks to silc_server_daemonise like to check
2231 whether the requested user and group actually exists.
2233 * Added sanity check to SKE's silc_ske_responder_finish to check
2234 that the public and private key actually is valid.
2236 * Invalidate the client's nickname when receiving Replace ID
2237 packet and the Client ID is being replaced. This means that the
2238 server will query the nickname if someone needs it (client)
2241 * Sort the ID Cache in client library when the ID Cache data
2242 has changed (needs sorting).
2244 * Do not allow for SILC client to create several connections to
2245 several servers. The client does not support windows right now
2246 and generating multiple connections causes weird behaviour.
2248 Irssi-silc client does support windows and can handle several
2249 connections without problems, see: www.irssi.org and SILC plugin.
2251 * Fixed some places where client was added to the IDList. The
2252 rule of thumb is following (in order to get everything right):
2253 If the client is directly connected local client then the
2254 `connection' argument must be set and `router' argument must be
2255 NULL to silc_idlist_add_client function. If the client is not
2256 directly connected client then the `router' argument must
2257 bet set and the `connection' argument must be NULL to the
2258 silc_idlist_add_client function.
2260 * The funtion silc_server_packet_send_local_channel actually did
2261 not check whether the client was locally connected or not. It
2262 does that now. Fixed a bug related to LEAVE command.
2264 * Fixed Remove Channel User payload parsing bug in server's
2265 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2267 * The server's silc_server_save_channel_key now checks also the
2268 global ID list for the channel as it might not be in the local
2269 list. Fixed a bug related to LEAVE command.
2271 * Is this the end of the [<unknown>] buglet that has been lurking
2272 around for a long time? A little for loop fix in server's
2273 silc_server_command_whois_parse that is used by both IDENTIFY
2274 and WHOIS command. At least, this was a clear bug and a cause
2275 of one type of [<unknown>] buglet.
2277 * WHOIS and IDENTIFY commands call the function
2278 silc_server_command_[whois/identify]_check function even if
2279 we are not router server.
2281 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Added --with-gmp configuration option. If set the GMP
2284 is always compiled in the SILC source tree. If not set then
2285 it is checked whether the system has the GMP3 installed. If
2286 it has then the GMP won't be compiled (the system's headers
2287 and library is used), if it doesn't have it then the GMP is
2288 compiled in the SILC source tree.
2290 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Changed RSA private exponent generation to what PKCS #1
2293 suggests. We try to find the smallest possible d by doing
2294 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2295 not security fix but optimization.
2297 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Added new config entry [Identity] to fork the server and run
2300 it as specific user and group. A patch from Bostik.
2302 * Imported Dotconf configuration library into lib/dotconf.
2303 This will be used to create the SILC configuration files later.
2304 It will appear in the distsribution after this commit.
2306 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2308 * A big code auditing weekend happening. Auditing code for
2309 obvious mistakes, bugs and errors. Also, removing any code
2312 Removed files for being obsolete:
2314 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2315 inline in the file lib/silcutil/silcbuffer.h)
2317 o lib/silcutil/silcbufutil.c (the header has inline versions)
2319 Changed code to fix possible error conditions:
2321 o The buffer formatting routines now check that the destination
2322 buffer really has enough space to add the data. This applies for
2323 both buffer formatting and unformatting
2324 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2325 unformatting was changed to accomodate following rules:
2326 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2327 sent to the function while XXX_*STRING will not allocate or copy
2328 the data into the buffer. Instead it sets the pointer from the
2329 buffer into the pointer sent as argument (XXX_*STRING used to
2330 require that the pointer must be allocated already). This change
2331 makes this whole thing a bit more consistent and more optimized
2332 (note that the data returned in the unformatting with XXX_*STRING
2333 must not be freed now). The routines return now -1 on error.
2335 o Tried to find all code that use buffer_format and buffer_unformat
2336 and added return value checking to prevent formatting and
2337 especially unformatting errors and possible subsequent fatal
2340 o Changed ske->x and ske->KEY to mallocated pointers in
2341 lib/silcske/silcske.h. Fixed possible data and memory leak.
2343 o Added return value checking to all *_parse* functions. Fixed
2344 many memory leaks as well.
2346 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2347 so that buffer overflows would not happen. All code now also
2348 checks the return value as it can fail.
2350 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Added reconnection support to server if the normal server looses
2353 its connection to the router (for example if router is rebooted).
2354 The server performs normal reconnection strategy implemented
2355 to the server. Affected file silcd/server.c.
2357 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2359 * Added new packet type SILC_PACKET_SET_MODE that is used to
2360 distribute the information about changed modes (for clients,
2361 channels and clients channel modes) to all routers in the
2362 network. Updated the protocol specification accordingly.
2364 Added functions into silcd/packet_send.c and
2365 silcd/packet_receive.c: silc_server_send_set_mode,
2366 silc_server_set_mode.
2368 Added new files silcmode.[ch] into lib/silccore that implements
2369 the encoding and decoding of Set Mode Payload. Added new type
2370 SilcSetModePayload. Moved the definitions of different modes
2371 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2373 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2375 * Oops, a little mistake in server's connection authentication
2376 protocol. The protocol is not ended with FAILURE but with
2377 SUCCESS if the authentication is Ok. :) Affected file is
2380 * Implemented NICK_CHANGE notify handling in server in the file
2381 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2382 the local clients on the channel. After the changing nickname
2383 in router environment snhould work and the [<unknown>] nickname
2384 should appear no more.
2386 The silc_server_replace_id function that receives the Replace ID
2387 payload now sends the NICK_CHANGE notify type also in the file
2388 silcd/packet_receive.c
2390 * Changed WHOIS and IDENTIFY command to support the maximum amount
2391 of arguments defined in protocol specs (3328 arguments). This
2392 fixed a bug that caused problems when there were more than three
2395 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2397 * Added extra parameter, command identifier, to the
2398 silc_client_send_command so that explicit command identifier
2401 Changed that ID list routines uses specific command identifier
2402 when sending WHOIS/IDENTIFY requests to the server so that they
2403 can be identified when the reply comes back.
2405 Affected files lib/silcclient/command.[ch],
2406 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2408 * Added `sender' argument to silc_server_packet_send_to_channel
2409 to indicaet the sender who originally sent the packet to us
2410 that we are now re-sending. Ignored if NULL. Affected file
2411 silcd/packet_send.[ch].
2413 * Added some server statistics support in silcd/server_internal.h
2414 SilcServerStatistics structure and around the server code. Also
2415 send some nice statistics information when client is connecting
2418 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2420 * Fixed channel ID decoding in server's JOIN command reply in
2421 silcd/command_reply.c
2423 * Fixed braodcasting of replace ID payload to not to send it if
2424 we are standalone server in silcd/packet_receive.c.
2426 * Fixed all channel message sending routines to not to send
2427 packets to clients that has router set, since they are routed
2428 separately in the same function earlier. Affects file
2429 silcd/packet_send.c and all channel packet sending functions.
2431 * In USERS reply, res_argv[i] are not allocated, the table
2432 is allocated. Thus changed that free the table, not its
2435 * In server's whois_check and identify_check if the client is
2436 locally connected do not send any WHOIS commands - they are not
2439 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2441 * Fixed some minor bugs in client when sending WHOIS command. The
2442 arguments was in wrong order.
2444 * Removed statis function add_to_channel from server in
2445 silcd/command.c that was previously used with the joining but
2448 * Tested USERS command in router environment successfully with two
2449 routers, two servers and two clients.
2451 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2453 * Reorganized the USERS command and command reply in client library
2454 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2455 When the command is given by user we register a pending command
2456 callback that will reprocess the command after the reply has been
2457 received from the server. When reprocessing the packet we then
2458 display the information. Thus, the USERS information is displayed
2459 now in the command callback instead of in the command reply
2460 callback. The processing of the command is same as previously
2461 when server has sent the command reply in the JOINing process.
2463 * Added to USERS command in silcd/command_reply.c to join the client,
2464 we didn't use to know about, to the channel after we've created
2465 a client entry for it. Also, for clienet we did know already still
2466 check whether it is on the channel or not and add it if not.
2468 * Removed silc_server_command_join_notify as the function and its
2471 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Changed the client's pending command handling to the same as the
2474 server's pending command handling. It is also now possible to
2475 execute command reply functions from other command reply
2476 function as the function callbacks for commands and command
2477 replies are one and same. The pending commands are not static
2478 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2479 in client connection context. Thus, pending commands are server
2480 connection specific as it is convenient.
2482 Changed the function silc_client_command_pending and
2483 silc_client_command_pending_del and added new function
2484 silc_client_command_pending_check. Removed the
2485 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2488 * Added cmd_ident, current command identifier, to the client
2489 connection context in lib/silcclient/client.h to keep track on
2490 command identifiers used in command sending. Client's command reply
2491 function handling now supports the mandatory command identifiers.
2493 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2494 funtions in client to fully support pending command callbacks.
2496 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2497 as one of the arguments to the application in the command reply
2500 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2501 before first releasing SILC but came back. Now it is removed again
2502 and should come back nomore. The FORWARDED flag was used only
2503 by the JOINing procedure by forwarding the command packet to router.
2504 Now, the JOINing procedure has been changed to more generic (due
2505 to various router environment issues) and FORWARDED is not needed
2506 anymore for anything. The protocol specification is yet to be
2509 Now, removed silc_server_packet_forward from server and the flag
2510 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2512 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Renamed NAMES command to USERS command. The NAMES was named that
2515 due to historical reasons. Now it is renamed. Also, rewrote
2516 parts of the USERS command. The nickname list is not sent anymore
2517 by the server. Only Client ID and mode lists are sent in the USERS
2518 command. Changed this also to the protocol specification.
2520 The client now resolves the names and stuff after it receives
2521 the USERS list from the server when joining to the channel.
2523 * WHOIS and IDENTIFY commands has been changed to support multiple
2524 Client ID's per command. One can now search for multiple users
2525 in the network by sending only one WHOIS or IDENTIFY command.
2526 Changed the code and the protocol specifications.
2528 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2529 uses silc_server_command_whois_parse to parse the request. */
2531 * If normal server, do not parse the WHOIS and IDENTIFY requests
2532 before sending it to the router. Saves some time.
2534 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2536 * Fixed JOIN command on client library. Wrong number of arguments
2537 used to crash the client.
2539 * Added silc_server_channel_has_global function to check whether
2540 channel has global users or not.
2542 * Added silc_server_channel_has_local function to check whether channel
2543 has locally connected clients on the channel.
2545 * The silc_server_remove_from_one_channel now checks whether the
2546 channel has global users or not after given client was removed from
2547 the channel. It also checks whether the channel has local clients
2548 on the channel anymore. If it does not have then the channel entry
2549 is removed as it is not needed anymore.
2551 * The silc_server_notify now checks on JOIN notify whether the joining
2552 client is one of locally connected or global. If it is global then
2553 the channel has now global users on the channel and that is marked
2554 to the channel entry. Also, it now saves the global client to
2555 global list who is joining and JOINs it to the channel. This is
2556 for normal server, that is.
2558 Changed silc_server_send_notify_on_channel,
2559 silc_server_packet_relay_to_channel and
2560 silc_server_packet_send_to_channel check if we are normal server
2561 and client has router set (ie. global client) do not send the
2562 message to that client, as it is already routed to our router.
2564 * Implemented LEAVE notify type handling in silc_server_notify
2567 * Tested LEAVE command in router environment successfully. Tested
2568 with two routers, two servers and two clients.
2572 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2574 * Implemented SIGNOFF notify type handling in silc_server_notify
2577 * silc_server_remove_id now removes the client entry from all channels
2578 it has joined and thusly sends SIGNOFF notify type.
2580 * Rewrote the NAMES list generation in server by removing two excess
2581 loops. The lists are created now inside one loop.
2583 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2585 * silc_server_remove_channel_user checks now also global list
2586 for channel and client.
2588 * silc_server_new_channel_user checks now both local and global
2589 list for channel and client. Fixed a bug in client id decoding.
2590 Used to decode wrong buffer.
2592 * silc_server_channel_message checks now both local and global
2593 list for channel entry.
2595 * Tested channel joining (hence JOIN) in router environment
2596 successfully. Tested with two routers, two servers and two
2599 * Tested channel message sending in router environment successfully.
2601 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2603 * Added silc_server_save_channel_key into server.[ch] to save the
2604 received channel key in Channel Key payload processing. It is
2605 also used in JOIN command reply handling.
2607 Equivalent function silc_client_save_channel_key added into
2608 client.[ch] into client library.
2610 * Changed JOIN command reply to send information whether the channel
2611 was created or not (is existing already) and the channel key
2612 payload. Changed protocol specs accordingly.
2614 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2615 the request was sent by ID and not by nickname. Crashed on
2618 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2620 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2621 now correctly save the received data.
2623 * silc_server_free_sock_user_data now notifies routers in the
2624 network about entities leaving the network.
2626 At the same time implemented functions silc_server_remove_id
2627 and silc_server_send_remove_id to receive and send REMOVE_ID
2628 packets. The packet is used to notify routers in the network
2629 about leaving entities. The ID removed will become invalid in
2632 * Added function silc_idlist_del_server into server. Removes and
2633 free's server entry from ID list.
2635 * silc_server_private_message function now checks, if we are router,
2636 that the destination ID really is valid ID, naturally.
2638 * In router when NEW_ID packet is received (for new client) the
2639 hash of the Client ID is saved in the ID Cache but the
2640 client->nickname is set to NULL, instead of putting the hash
2643 IDENTIFY command now also checks that client->nickname must be
2644 valid. If it is not if will request the data from the server who
2645 owns the client. Added new function
2646 silc_server_command_identify_check.
2648 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2649 to set the command to already allocated Command Payload.
2651 * Tested private message sending in router environment with two
2652 routers, two servers and two clients. Fixed minor bugs and now
2655 * Fixed segfault from client's NAMES command. Used to crash if
2658 * Forwarded packets must not be routed even if it is not destined
2659 to the receiver. Changed server code comply with this.
2661 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2663 * Added `require_reverse_mapping' boolean value to ServerParams
2664 structure. If TRUE (not default) the server will require that
2665 the connecting host has fully qualified domain name.
2667 If the reverse mapping is not required and hostname could not be
2668 found the IP address is used as hostname.
2670 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Implemented version string checking to both client and server.
2673 The check is incomplete currently due to the abnormal version
2674 strings used in development version of SILC.
2676 * Changed all command functions in server to use the new
2679 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Changed char *data to unsigned char *data in ID Cache system to
2682 support binary data as ID Cache data. Changed code to support
2683 binary data in lib/silccore/idcache.c.
2685 * Renamed silc_server_packet_relay_command_reply to
2686 silc_server_command_reply as it is normal packet receiving
2687 function. Rewrote the function to accept command replys for
2688 servers and not only for clients.
2690 * Mark remote router always as registered server if we are connecting
2691 to it. Otherwise, commands sent by the router to us are ignored.
2693 * All ID List find routines now returns the ID Cache Entry pointer
2694 as well if requested.
2696 * WHOIS command works now in router environment, tested with two
2697 routers, two servers and two clients.
2699 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2700 in router environment (as it is almost equivalent to WHOIS) but
2701 hasn't been tested thoroughly. Added new functions:
2703 silc_server_command_identify_parse
2704 silc_server_command_identify_send_reply
2705 silc_server_command_identify_from_client
2706 silc_server_command_identify_from_server
2708 * Disabled route cache adding because adding two different ID's with
2709 same IP replaces the old cache entry thus giving wrong route.
2710 The entry->router->connection is always the fastest route anyway
2711 so route cache may not be needed. Of course, new routes maybe
2712 established after receiving the ID when the entry->router->connection
2713 might not be anymore the most optimal.
2715 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2717 * Add route cache for received ID for fast routing.
2719 * Added silc_server_packet_route to route received packet on router
2720 that is not destined to us.
2722 * Renamed silc_server_get_route to silc_server_route_get.
2724 * Added id_string and id_string_len fields into SilcServer to
2725 include encoded ServerID for fast comparing without excess
2726 encoding of the ID's.
2728 * Cleaned up WHOIS command on server side. Added following static
2731 silc_server_command_whois_parse
2732 silc_server_command_whois_check
2733 silc_server_command_whois_send_reply
2734 silc_server_command_whois_from_client
2735 silc_server_command_whois_from_server
2737 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2738 arguments in command replies. All command functions should be
2739 updated to use this macro.
2741 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2743 * Minor typo fixes on command reply handling on server.
2745 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * Added silc_server_command_add_to_channel internal routine to add
2748 the client to the channel after router has created the channel and
2749 sent command reply to the server.
2751 * Added generic silc_server_send_command to send any command from
2754 * Use static buffer with ID rendering instead of duplicating data.
2756 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Fixed a channel user mode bug when joining to a channel server gave
2759 everybody channel founder rights, oops.
2761 * We mark ourselves as the router of the incoming server connection
2762 if we are router ourselves. This way we can check in some packet
2763 sending functions whether it is locally connected server. For
2764 incoming router connections we put NULL.
2766 * For router sending packets locally means now always sending the
2767 packet cell wide; to local clients and local servers. For normal
2768 server sending packet locally means sending it to only local
2771 * Fixed the JOIN command to really work in router environment. If the
2772 channel is created it is always created by the router. Router is
2773 also responsible of making the initial joining to the channel,
2774 sending JOIN notify to the sending server and distributing
2775 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2776 does not exist server doesn't do anything else but forward the
2777 command to the router which performs everything.
2779 * Added silc_server_send_channel_key function to send the Channel Key
2782 * Added silc_server_create_channel_key to create new channel key. The
2783 channel key is now re-generated everytime someone joins or leaves
2784 a channel, as protocol dictates. Note: channel->key_len is the
2787 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2790 packet_receive.[ch] to separate packet sending and receiving
2791 routines. The server.[ch] now includes everything else including
2792 actual packet processing (writing and reading data) and other
2795 Renamed silc_server_private_message_send_internal to
2796 silc_server_send_private_message. The routine is still though
2797 used only to relay private messages as server does not send
2798 private messages itself.
2800 Renamed silc_server_new_channel to silc_server_create_new_channel
2801 and added new function sicl_server_new_channel that handles the
2802 incoming New Channel packet. Added also new sending function
2803 silc_server_send_new_channel to send New Channel Payload.
2805 * Added new function silc_server_notify to process incoming notify
2806 packet to the server/router. Server may then relay the notify
2807 to clients if needed.
2809 * Added new function silc_server_new_channel_user to process incoming
2810 New Channel User packet. Router will redistribute the packet and
2811 send JOIN notify to its local clients and locally connected servers
2812 if needed. Normal server will send JOIN notify to its local client
2813 on same channel when received this packet. Added also corresponding
2814 sending function silc_server_send_new_channel_user to sent the
2817 * Added boolean route argument to send_notif_to_channel and
2818 packet_send_to_channel functions to attempt to route the packet
2819 if it is TRUE and send only locally if it is FALSE.
2821 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * silc_server_replace_id now broadcasts the received replace ID
2824 packet if it is not broadcast packet already. The router must
2825 broadcast to inform other routers about changed ID.
2827 * Added backpointer to server's router into SilcServer context in
2828 silcd/server_internal.h.
2830 * Fixed silc_server_packet_broadcast to send correct broadcast
2833 * The channel key is now distributed to the local client as soon
2834 as it is received from the router (in router environment) so that
2835 no other packet may be sent for the channel until client has
2838 * silc_server_remove_channel_user now broadcasts the received
2839 Remove Channel User packet if it is not broadcast packet already.
2840 The router must broadcast to inform other routers about removed
2843 * Added users field into SilcPacketContext that is a reference count
2844 of the context. One can increase the reference count by calling
2845 silc_packet_context_dup which is now changed to just increase the
2846 reference count instead of duplicating the data. The reference
2847 count is decresed by calling silc_packet_context_free that will
2848 free the data after the reference count hits zero.
2850 For now on the packet context and everything allocated into it
2851 (including the raw packet from network) must be freed by calling
2852 the new silc_packet_context_free function. Added also new function
2853 silc_packet_context_alloc that must be used now to allocate the
2854 context. This also means that if a routine is asynchronous from
2855 silc_[client/server]_packet_parse_type the packet context must
2856 be duplicated by calling silc_packet_context_dup. Otherwise it
2857 gets free'd after silc_[client/server]_packet_parse_type returns.
2858 Also, one must remember that if packet is duplicated then its
2859 reference count must be decresed by calling the free function as
2860 many times as it was duplicated.
2862 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2863 from both client and server.
2865 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Made joining to a channel working in router environment.
2869 * Cleaned up JOIN command on server side and create function
2870 silc_server_command_join_channel internal routine to make the
2873 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2875 * Changed silc_command_pending list to SilcDList. Also, added
2876 `ident' field to SilcServerCommandPending structure to identify
2877 the reply and to call correct callback.
2879 Added silc_server_command_pending_check function to replace the
2880 corresnponding macro. The silc_command_pending list is not
2883 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2884 to set identifier to previously allocated Command Payload. It
2885 is used to set identifier for command when resending Command
2888 * Added silc_command_payload_encode_payload to encode Command
2889 Payload buffer from SilcCommandPayload structure.
2891 * Added silc_argument_payload_encode_payload to encode Argument
2892 payload buffer from SilcArgumentPayload structure.
2894 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * Changed WHOIS command to support router connection on server side.
2897 The whois request is always sent to router unless the server is
2898 standalone server. After server has received the reply from the
2899 router will it send the reply to the client.
2901 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2902 broadcast received broadcast packet. The function is used only
2903 by router. The broadcast packet is always sent to the router's
2906 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2907 render given ID to printable string, for log files for example.
2909 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Made basic router to router connections working. At least they
2912 can now connect to each other but nothing really works the way
2913 they are supposed - yet.
2915 * Added new initiator token to RouterConnection configuration
2916 file in silcd/serverconfig.[ch]. It is used to tell whether we
2917 are the initiator to the remote router or whether we'll expect
2918 the other end to connect.
2920 * Moved registering of listener task to silc_server_init, hence
2921 the server starts listenning as soon as it is run, even if it
2922 does not have connections to other routers. Let's see how well
2925 * Changed default connection retry timeouts for more suitable in
2928 * Removed cipher and such arguments from silc_idlist_add_client
2929 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2930 Added new function silc_idlist_add_data to add the keys and stuff
2933 * Added SilcIDListData structure and added it to SilcClientEntry
2934 and SilcServerEntry as their first field in the structure. This
2935 way we can explicitly cast the ID entries to the SilcIDListData
2936 structure and get common data for the entries. In past, we had
2937 to first check what type of connection it is and then cast it to
2938 correct ID entry type. Now, we can directly cast the opaque
2939 pointer to the SilcIDListData (no matter what ID entry it actually
2940 is) and get the data needed.
2942 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2944 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2945 in some circumstances even if threre were timeout tasks, though not
2946 IO tasks, but tasks anyway. Now fixed.
2948 * Defined SilcServerConnection structure to hold connection specific
2949 stuff about directly connected servers and routers. The definition
2950 is currently in silcd/server_internal.h. I thought about having
2951 a bit more important role fro this struct but for now it is used
2952 only when connecting to other server (or router actually).
2954 * Added connecting retry support in server when connecting to
2955 router(s). The retry feature implement exponential backoff
2956 algorithm. Also, added SilcServerParams structure to hold default
2957 parameters for server. For now, it include these retry settings
2958 and are hard coded. After server is moded to be as Silc Server
2959 Library this structure will be more important.
2961 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2963 * Changed client librarys channel->clients table to SilcList and
2964 changed code accordingly.
2966 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2968 * Changed client's channel table to SilcList and changed code
2969 accordingly. Also changed SilcChannelClientEntry to include back-
2970 pointer to the channel so that client entry can use that structure
2971 as list as well and we have fast cross-reference to the channel.
2972 This change dramatically decreased the complexity of channel
2973 handling with client entry and vice versa (removed one extra
2974 loop when searching for channel entry from many functions).
2976 * Changed server->sim from table to SilcDList and changed code
2979 * NAMES command can now be used from user interface. It will show
2980 the user list on the channel, neatly.
2982 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2983 Code now saves realname of the user if it becomes available.
2985 * Renamed configure.in to configure.in.pre and made ./prepare
2986 script to automatically add correct version string to
2987 configure.in which it creates from configure.in.pre.
2989 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2991 * NAMES command reply now shows users mode with the nickname when
2994 * Moved silc_client_ch[u]mode[_char] functions from
2995 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2996 place sucks, they are utility functions and should be in some
2999 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3001 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3004 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Added TRQ (efficient deque and list library) into lib/trq. This is
3009 a very good list library that is currently used in the SILC. Defined
3010 SilcList API over the library because I didn't like the API very
3011 much. See lib/trq/silclist.h for the API and examples of how to
3012 use the API. Fixed various places in the code to use the new
3013 SilcList API. The SilcList is meant for lists that has a structure
3014 already defined as a list. It is not suitable to add just some
3015 context to the list (in TRQ, the context is the list actually).
3017 So, I defined SilcDList that can be used for the purpose where
3018 predefined list structure does not exit. This can be used as
3019 such list. Now some context just can be added to the SilcDList.
3020 Currently this list is not used in the SILC just yet, though there
3021 are a lot places where this can replace dynamically allocated
3022 tables and I will fix these places, later, to use SilcDList.
3023 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3024 and use TRQ internally).
3026 Also fixed some annoying warning messages that the original TRQ
3027 code generated. Also minor changes to TRQ's Makefile.in.
3029 * Added support for querying by Client ID to both WHOIS and
3030 IDENTIFY commands into server, as required by the protocol.
3032 * Removed method function pointers from SilcBuffer structure. They
3033 weren't used to anything and just increased the context size for
3034 no good reason. This change also made silc_buffer_alloc and
3035 silc_buffer_free functions inline functions.
3037 * Disabled command flooding detection support until it's fixed so
3038 that it accepts commands in but does not execute them more than once
3041 * Added silc_net_localhost(), to return local hostname, into
3042 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3043 that must be initialized before calling silc_client_init.
3045 * Added new function: silc_server_send_notify_on_channels to send
3046 notify messages to all channels client has joined. It is assured
3047 that the message is sent only once per client.
3049 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3050 lib/silcutil/silcutil.[ch] as silc_format function. The new
3051 function is generic and is used by server as well, not only by
3052 the logging routines.
3054 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3055 the provided version string was not acceptable. Added new function:
3056 silc_ske_check_version into lib/silcske/silcske.h. The function
3057 must be implemented by the application (client or server) and it
3058 does not reside in the SKE library. The function checks the version
3059 string remote end sent.
3061 * Added back pointers (to opaque context and to SilcSocketConnection)
3062 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3064 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3065 duplicate packet context structure.
3067 * Changed `notify' client operation to send same arguments as client
3068 receives from server except for ID's. ID's are mapped to correct
3069 ID entry and that is returned. Also, if channel entry is not sent
3070 by server but the notify is for channel the channel entry is sent
3071 to application (otherwise application doesn't know that it is for
3072 channel (library gets it from packet's Destination ID)).
3074 * Added silc_client_remove_from_channels into client library to
3075 remove a client from all channels it has joined to. Used when
3076 received SIGNOFF notify from server. Added also new function
3077 silc_client_replace_from_channels to replace old ID entry with
3078 new ID entry on all channels. Used when received NICK_CHANGE
3081 * Fixed ID Cache list handling in silc_idlist_get_client in
3082 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3083 to get (or query) client by ID.
3085 * Updated TODO list.
3087 * Added connection authentication status message defined by the
3088 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3089 support for these into the code in client and server side.
3091 * Added generic function silc_client_send_command to send any command
3092 with variable argument list. Application should use this function
3093 to send commands if the command functions provided by the library
3094 does not suite for the application's user interface needs.
3096 * Added new `failure' client operation. Application is notified about
3097 received failure packet if client is executing a protocol. In this
3098 case the protocol's execution has failed.
3100 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3101 is required by the protocol.
3103 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3104 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3107 * Added status flag to SilcSKE object to indicate realtime status
3108 of the SKE protocol.
3110 * Application receives now exactly same command reply arguments as
3111 the library receives from server. However, if ID is received the
3112 corresponding ID entry is returned to the application (eg. Client
3113 ID is mapped to correct SilcClientEntry entry and that is returned).
3114 Changed command_reply client operation due to this change.
3116 * Changed all ID's in commands and in command replys as ID Payloads.
3117 Change affected both client and server side codes.
3119 All ID's sent in SILC network (with execption of ID's in SILC
3120 Packet header) are sent in ID Payload to support variable length
3123 * Server now notifies nick changes and notifies all clients on
3124 the channels about the new nickname (about the new Client ID,
3127 * Implemented CMODE command to change channel modes. Supports all
3128 channel modes defined by the protocol specs except ban and invite
3129 lists. (Also, private channel key mode is supported but support for
3130 setting private channel key in client is missing, thus, this mode
3131 has no effect on client side (except that server requires that the
3132 client uses private channel key and normal channel traffic does not
3135 Also, invite mode works per se, but INVITE command does not work
3136 yet correctly, so you can set channel as invite only channel but
3137 inviting clients to the channel does not work (it is yet to be
3138 thought what's the best way to do it).
3140 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3141 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3142 Implemented CUMODE command to change user's mode on the channel.
3143 Supports all modes defined by the protocol specs.
3145 * Added NAMES command reply to return users modes on the channel.
3147 * Removed unnecessary and slow ciphers from lib/silccrypt.
3149 * Set SO_KEEPALIVE option to connection sockets by default.
3151 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3153 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3154 redefined the Notify Payload into protocol specs.
3156 * Added silc_id_payload_parse_id to get ID directly from raw
3159 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3162 accept searching by Client ID as well.
3164 * Added support for LEAVE and SIGNOFF notify types in client library.
3166 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3167 to parse ID Payload from raw data.
3169 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Added flags parameter into silc_ske_assemble_security_properties
3172 function in lib/silcske/silcske.[ch].
3174 * Changed notify client operation to fit better for notify messages
3175 sent by server. The notify payload received from server is now
3176 passed to the application (after parsing it to SilcNotifyPayload).
3177 It is application's responsibility to retrieve the arguments
3178 from the payload and show the message the way it wants. The message
3179 sent by server is implementation specific.
3181 * Changed public keys to comply with the protocol specification.
3182 Old public keys are not supported anymore and are not compatible.
3184 * Removed nickname from Channel Payload as the latest draft removed
3185 it. The client must resolve the nickname from the NAMES command
3186 reply received when it joined the channel.
3188 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3190 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3192 * Fixed some errors in protocol specification drafts.
3194 * Created lib/silccore/silcnotify.c to implement Notify Payload
3195 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3196 generic payloads described by protocol specifications. The file
3197 includes implementations for ID Payload and Argument Payload.
3199 * Changed Command Payload implementation to use the new Argument
3200 Payload. Changed command_xxxx_payload to command_payload_xxxx
3201 to comply with SILC coding conventions.
3203 * Added suppport for Argument Payload handling in Notify Payload
3204 implementation as protocol requires it. Added the new support
3205 into server and client lib as well.
3207 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3209 * Added support for multiple nicknames on same channel. [n] is
3210 added locally to the nickname if there are more than one same
3211 nicknames on the channel.
3213 * Server now sends all nicknames that matched WHOIS request.
3214 Client also shows the list received from server.
3216 * Added TOPIC command to client side. User can now set and show
3217 current topic on channel.
3219 * Added MOTD command to client and server. Also, server sends the
3220 motd when client connects to the server.
3222 * Changed version strings to comply ISO 8601.
3224 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3226 * Fixed protocol error handling in client library. It should now
3227 cope even if the SKE fails for some reason.
3229 * Made new protocol specification drafts for submitting to IETF.
3231 * Implemented TOPIC command to server in silcd/command.c.
3233 * Added two new notify types into lib/silccore/silcnotify.h:
3234 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3235 notify nickname change and topic setting/change on a channel.
3237 * API change of command_reply operation in client library. The
3238 application gets now the status type received from server as well.
3240 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3244 * Cras fixed and optimized the packet handling even further and
3245 it should work now. Minor change to the prototype of function
3246 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3248 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3250 * Added new function into lib/silcutil/silcschedule.[ch]:
3251 silc_schedule_with_fd to select() a specified fd. The function
3252 returns after timeout expires or data arrives or goes. The
3253 function is used by packet routines to wait that all data is
3254 received from network.
3256 * Fixed data reading from network in lib/silccore/silcpacket.c.
3257 The code now assures that all data is read from the fd and then
3258 continues packet processing. This was a bug fix since the code
3259 used to drop some data in some circumstances.
3261 * Added new function into lib/silcclient/client.[ch]:
3262 silc_client_start_key_exchange to start key exchange after
3263 connection has been established to server. The code internally
3264 now uses this funtion but its main purpose was to provide it
3265 for applications that perform their own connecting. After
3266 application has created a connection it merely calls this
3267 function to start the key exchange between client and server.
3268 The library takes care of everything else after that.
3270 Updated also lib/silcclient/README to explain the usage of
3273 * Do not send to application information that connection has
3274 been established. Application gets notified it by connect
3277 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Applied cras's patch to add silc_schedule_one function. The
3280 function runs scheduler once and returns.
3282 * Fixed the scheduler after cras messed it up. The timeout
3283 handling works now as it's supposed to work.
3285 * Added into lib/silccore/ silcnotify.h to include notify
3286 message types support. Changed silc_server_send_notify*
3287 functions, in server.[ch], to support those new notify types.
3288 Added the support for the notify types into client library,
3289 as well. Added new notify client operation into ops.h in
3292 * Changed silc_server_packet_send_to_channel to send normal
3293 packets instead of just channel message packets. The function
3294 is now used to send the notify packets to channels. It is not
3295 used to send channel message packets anymore, as server never
3298 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3299 va_arg()s as it seems to require it nowadays. I guess, if SILC
3300 is compiled with older va_arg() the new code should work anyway.
3302 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Splitted core library. Core library (lib/silccore) includes
3305 now only SILC protocol specific core (and common) components.
3306 Created new utility library (lib/silcutil) that includes more
3307 generic purpose stuff. The stuff for util library was taken
3308 from the old core library. This was minor and easy split.
3310 * Created SILC Client Library (lib/silcclient) that includes
3311 implementation of the SILC client without user interface. This
3312 was major move from silc/ directory. The code has been changed
3313 so that it is transparent towards the user interface. The
3314 silc/ directory includes now the same user interface as before
3315 and it uses the new client library. Read lib/silcclient/README.
3316 Basicly, the client library performs everything else related
3317 to SILC except user interface handling. Also, configuration
3318 files are considered to be part of user interface and library
3319 does not handle them.
3321 This change also changed a lot of structures, function naming etc.
3322 Most important change was that SilcClientWindow object was
3323 renamed to SilcClientConnection in the client library. Created
3324 also new file lib/silcclient/ops.h. Also added new files
3325 silc/local_command.[ch] and silc/client_ops.[ch].
3327 All these changes were made to make it easier for user interface
3328 designers to create what ever user interface for the SILC client
3331 It is also expected that the server will be moved to lib
3332 directory as well and SILC Server Library will be created;
3333 sometimes in the future.
3335 * Removed Local commands from lib/silccore/silccommand.h as
3336 they are application specific and new client library does not
3337 handle any of those anymore.
3339 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3340 old client implementation in silc/.
3342 * Added support for callback functions in SILC_LOG_* macros.
3343 Application can now set its own callbacks that will be called
3344 instead of using the default functions that will always print
3345 the debug messages to stderr (or stdout). Also, debugging can
3346 now be disabled by setting silc_debug to FALSE and re-enabled by
3347 setting it to TRUE. Note, that logging will still work even
3348 if debugging is disabled.
3350 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3351 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3352 silc_log_reset_debug_callbacks.
3354 * To enable debugging in silc client one must give now -d
3355 option on command line.
3357 * Changed silc_schedule_init to automatically allocate task queues
3358 if they are not allocated before calling it.
3360 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Added GMP 3.1 into math library.
3364 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3366 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3367 a channel in SILC network. The packet is used by servers and
3368 routers to notify other routers that user has left a channel.
3369 This little feature was missing until now. Added the feature
3370 to protocol specification as well.
3372 Added functions: silc_server_send_remove_channel_user and
3373 silc_server_remove_channel_user into server.[ch].
3375 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3376 lib/silccore/silcpacket.h. However, they are not implemented
3379 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Fixed joining to a channel and sending channel messages
3382 between server and router. The channel message sending should
3383 now work inside a cell.
3385 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Fixed the private message sending between server and router.
3388 The private message sending should now work inside a cell.
3390 * Added silc_server_replace_id into server.[ch] to replace
3391 existing ID in the SILC network.
3393 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3394 and silc_idlist_replace_server_id into idlist.[ch] in server.
3396 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * Fixed the server to server connections. Server can again now
3399 connect to router. Router to router connections probably does
3402 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3404 * Added dynamic protocol registering support. Now protocols can
3405 registered and unregistered on the fly. Patch by cras.
3407 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * Added lib/contrib directory to hold routines that some platforms
3410 don't have but are needed by SILC.
3412 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3413 into lin/contrib to provide getopt() and getopt_long() for
3414 those who don't have it.
3416 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3418 * Added AWAY command to client. When away message is set and
3419 client receives a private message packet the client automatically
3420 replies to the sender with the away message.
3422 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3423 bug seemed to be the cause of recent problems when compiling
3426 * Added version detection support to SKE protocol specification
3427 and added the new changes to the SKE implementation as well.
3428 There were other minor changes in the SKE protocol as well.
3430 Many changes in lib/silcske/silcske.[ch] and in
3431 lib/silcske/payload.[ch].
3433 * Added ^U functionality, clear input line. Patch from cras.
3435 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3437 * Mainly small bugfixes on core library. Fixed some debugging
3438 logging and buffer overflow in silclog.c.
3440 * Updated config.sub and config.guess on the distribution tree.
3442 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3444 * Added command lagging support in server. Client may execute
3445 commands now only once in two seconds.
3447 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Optimized packet reception. MAC computation and checking is now
3450 also more optimized. A lot previously duplicated code is now
3451 used as generic by both client and server.
3453 * Fixed key pair generation in clientutil.c
3455 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Added into lib/silccore/silcbufutil.[ch] new function;
3458 silc_buffer_realloc.
3460 * Moved generic packet sending/encryption functions to
3461 lib/silccore/silcpacket.[ch] from client and server. Some
3462 rewriting of the functions.
3464 * Moved all generic packet reception/decryption functions to
3465 lib/silccore/silcpacket.[ch] from client and server. The
3466 packet processing is now much cleaner in both client and server.
3467 These were major changes in both client and server.
3469 * Created many common functions in server to do packet sending.
3470 Previously code were duplicated a lot, this has been removed
3473 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3475 * Rewrote major parts of the ID cache system. Don't know
3476 whether it is better now or not but at least the API is more
3479 * Major rewrite on ID cache stuff on client because of the ID
3480 cache API changes. Added idlist.c to client.
3482 * Also major rewrite on ID cache stuff on server as well.
3483 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3484 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3485 in hand, instead they are all put into the ID cache system now.
3486 All server_idlist_* routines uses ID cache now instead of
3487 traversing its own lists (those lists does not exist anymore).
3488 SilcIDList though still exists. Also, SilcXXXEntry's are
3491 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * Finally made the SKE implementation compliant to the protocol
3494 specification. All mp integers are now binary encoded as
3495 opposed being HEX encoded.
3497 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3500 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3501 functions: silc_[encode/decode]_pem. Also added function
3502 silc_encode_pem_file to PEM encode with newlines ('\n') for
3505 * SILC public keys are now encoded either PEM or binary. Same
3506 option is for private keys as well. By default private keys
3507 are binary encoded and public keys PEM encoded. Silly HEX
3508 encoding were removed.
3510 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3511 function to create fingerprints.
3513 * Fixed a bug in SHA1; does not change the original data anymore.
3515 * Partly implemented INFO command on client and server side.
3516 Fixed CLEAR command. Changes to SERVER command; show current
3517 server(s) when giving command without arguments. Added
3518 VERSION command to client.
3520 * Added check to server that unregistered connections cannot
3521 execute commands (unless it is specificly allowed).
3523 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3525 * Fixed screen refresh.
3527 * Fixed channel joining bug from client. On some circumstances
3528 client tried to join to a channel it had already joined.
3530 * Added public key verification process into client's protocol.c.
3531 The client now verifies the public key from user and saves
3532 it into ~./silc/serverkeys/ directory.
3534 Added into: clientutil.[ch]: silc_client_verify_server_key.
3536 * Changed SKE protocol's silc_ske_initiator_finish function
3537 to accept callback function that verifies the received public
3538 key. Removed old silc_ske_verify_public_key function.
3540 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3543 silc_pkcs_private_key[_data]_set.
3545 * Made the password and public authentication more cleaner in
3546 server's protocol.c.
3548 * Removed historic and obsolete protocol `channel_auth' from
3549 both client and server.
3551 * Removed wrong way of sending command status messages from
3552 server to client in server's command.c. The old way violated
3553 protocol specification.
3555 Changes to silccore/silccommand.[ch]: removed
3556 silc_command_encode_status_payload -> not needed anymore,
3557 changed silc_command_encode_payload_va to accept extra
3558 argument on variable argument list. The argument type must
3559 now be provided to the function. Also, added new function:
3560 silc_command_encode_reply_payload_va which is same as
3561 normal command_encode_payload_va except command status type
3562 is provided as extra argument.
3564 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Added ~./silc directory handling. The directory includes the
3567 public and private keys for the client.
3569 Added silc_client_check_silc_dir, silc_client_create_identifier
3570 and silc_client_load_keys.
3572 * Implemented SILC protocol compliant public key. Added public
3573 and private key saving to and loading from files.
3575 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3576 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3577 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3578 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3579 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3581 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3582 silc_pkcs_load_[public/private]_key.
3584 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3586 * Added silc_server_get_route (route.[ch]) to get connection
3587 data for the fastest route for given ID.
3589 * Implemented INVITE command on client and server. The command
3590 were re-defined in the SILC Protocol Specification and the
3591 implementation now complies with the specification.
3593 * Implemented PING command on client and server.
3595 * Implemented NAMES command on client and server. The server side
3596 supports currently only normal server not router server yet.
3597 Some changes to NAMES definition in SILC protocol specification.
3599 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Implemented LEAVE command on client and server.
3603 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3604 again. This change was made to the protocol as well. Server
3605 should not violate the protocol specification anymore.
3607 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3609 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3610 was tested. SOCKS4 was not but should work anyway.
