3 * Do not say "You have left channel %s" in client library.
4 Moved it to the application. Affected files are
5 lib/silcclient/command.c and silc/client_ops.c.
7 * Fixed silc_client_get_clients. Command context was not
8 duplicated and was freed memory in the callback. Affected
9 file lib/silcclient/idlist.c.
11 * Do not say "you are now talking..." on JOIN command in the
12 client library. The appliation must handle it.
14 * Do not say ".. changed topic to" in command reply in the
15 client libary. The application must handle it.
17 * Fixed TOPIC command sending in the client library.
19 * Fixed a memory leak in silc_client_command_free in the file
20 lib/silcclient/command.c.
22 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
24 * Imported a modified version of Irssi client to the source tree.
25 The Irssi will be used to create a new client called
26 Irssi SILC. Imported to irssi/.
28 Added silc_core_init_finish function to the Irssi. Affected
29 file irssi/configure.in.
31 A lot changes in the Makefile.ams around the irssi tree.
33 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
35 * Do not rehash if the new size is same as the old size of the
36 hash table, in the silc_hash_table_rehash*. The affected file
37 lib/silcutil/silchashtable.c.
39 * Replaced hash_table_del_by_context calls from the server
40 (when channel->user_list and client->channels) to the
41 hash_table_del as it is sufficient and faster.
43 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
45 * Added silc_hash_table_list, silc_hash_table_get and the
46 SilcHashTableList structure to provide an alternative way to
47 traverse the hash table. The affected files are
48 lib/silcutil/silchashtable.[ch].
50 * Changed the server's idlist routines to use the hash table
51 routines to optimize the code.
53 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
55 * Replaced the client entry's `channel' list and channel entry's
56 `user_list' list to hash tables for optimized lookup. Changed
57 the code to use the hash table interface around the code.
58 Affected file lib/silcd/idlist.[ch].
60 * Added `auto_rehash' boolean argument to the function
61 silc_hash_table_alloc to indicate whether the hash table should
62 auto-rehash when it thinks is appropriate time. It will
63 increase the hash table size if the there is twice as much
64 entries in the table than the size of the table, and will
65 decrease the size if there are twice as less entries than
66 the size of the table.
68 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
70 * Fixed silc_xxx_get_supported to not crash at some circumstances.
72 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
74 * silc_idcache_purge_by_context deletes the entry now by context
75 as it is supposed to do. Affected file lib/silccore/idcache.c.
77 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
78 client is not anymore valid (WHOWAS givens the info) and not
79 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
81 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
83 * Removed the `data' and `data_len' arguments from the ID Cache
84 interfaces and added `name' argument. ID Cache does not handle
85 anymore the binary data only a names associated with given ID.
87 * When hashing a Client ID with silc_hash_id the entire ID is
88 not hashed anymore, instead only the hash of the Client ID is
89 hashed. This way we can access the Client ID from the cache
90 with Client ID but with the hash of the ID (which is a hash of
91 the nickname) as well without any difference in performance.
93 Added also silc_idcache_find_by_id_one_ext to do one on one
94 searching when we have the actual ID. Added also function
95 silc_hash_client_id_compare. The affected files are
96 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
98 * When hashing the name associated with a ID it is always done
99 in lowercase. This way we can access the cache without worrying
100 about case-sensitivity, even though, for example nicknames are
103 * Fixed a bug in server with channel message sending. It put
104 wrong ID type as destination ID. The affected file
107 * silc_idcache_del_by_context now deletes from all hash tables
108 by context. Affected file lib/silccore/idcache.c.
110 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
112 * Changed the client library to use the new ID Cache interface.
113 Changes around the source tree.
115 * Added silc_hash_table_rehash_ext to rehash with specific
116 hash function. Affected file lib/silcutil/silchashtable.[ch].
118 * Added silc_hash_string_compare to compare two strings in the
119 hash table. Affected file lib/silcutil/silcutil.[ch].
121 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
123 * Added new function silc_idcache_del_by_context into the
124 lib/silccore/idcache.[ch].
126 * Changed the server's ID list routines to use the new ID Cache
127 interface. Changes around the source tree.
129 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
131 * Added silc_hash_table_del[_by_context]_ext functions in to the
132 lib/silcutil/silchashtable.[ch].
134 Removed silc_hash_table_find_all* routines and added new
135 silc_hash_table_find_foreach to replace them.
137 Added silc_hash_table_replace_ext function as extended
138 replacing function. Separated the simple hash table interface
139 from the extended hash table interface in the file
140 lib/silcutil/silchashtable.h.
142 * Fixed minor bugs and changed it to use some of the new
143 hash table functions in lib/silccore/idcache.c
145 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
147 * Added new function silc_hash_table_find_all to return all keys
148 in the hash table by the specified key. As the hash table is
149 collision resistant it also makes it possible to have several
150 duplicate keys in the hash table. This function may be used to
151 find all of the keys from the hash.
153 Added user_context arguments to the SilcHashFunction,
154 SilcHashCompare and SilcHashDestructor to deliver user specified
157 Added new fuctions silc_hash_table_find[_all]_ext to do
158 extended lookup with specified hash and compare functions and
159 specified user contexts.
161 Added new function silc_hash_table_add_ext to add the key
162 with specified hash function and user context.
164 Added new function silc_hash_table_foreach to traverse all
165 entrys in the hash table. Added SilcHashForeach callback
168 Added new function silc_hash_table_del_by_context to delete
169 the entry only if the context associated with the key matches.
171 Affected files are lib/silcutil/silchashtable.[ch].
173 * Removed silc_hash_[server/client/channel]_id and added just
174 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
175 silc_hash_id_compare to compare two ID's using as the hash table
176 comparison function. Added also silc_hash_data to hash
177 binary data and silc_hash_data_compare to compare it.
179 * Removed silc_idlist_find_client_by_hash as it is not needed
180 anymore. Affected file silcd/idlist.[ch].
182 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
183 to use internally the SilcHashTable. The new ID Cache is a lot
184 faster than the old one. Some of the ID Cache interface was also
185 rewritten and obsolete and stupid functions were removed.
187 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
189 * Added entry_count field to the SilcHashTable to keep the number
190 of the entries in the table. Implemented the function
191 silc_hash_table_rehash. Added new function
192 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
194 Fixed a minor bug in silc_hash_table_free.
196 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
197 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
198 into the lib/silcutil/silcutil.[ch].
200 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
202 * Implemented a collision resistant hash table into the
203 lib/silcutil/silchashtable[ch]. See the header and the source
204 for the SilcHashTable API.
206 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Merged dotconf version 1.0.2 into lib/dotconf.
210 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
212 * Do not compile anything in lib/silcsim/* if the SIM support
213 is not enabled. The tree should now compile without problems
216 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
218 * Compiled the SILC under cygwin. Compiled and tested briefly
219 without problems. More tests needed. The SIMs didn't compile
222 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
224 * Fixed possible crash in silc_get_username in the
225 lib/silcutil/silcutil.c.
227 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
229 * Fixed a va_arg in silc/client_ops.c.
231 * Oops, RC5 routines were named AES and caused some problems
232 when not using SIM's. Affected file lib/silccrypt/rc5.c.
234 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Added new SilcIDIP structure into the lib/silccore/id.h and
237 replaced the old `ip' fields from all SILC ID's to that type.
238 This is a step towards IPv6 support.
240 The silc_id_get_len takes now the ID as an extra argument.
241 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
242 both IPv4 and IPv6 based ID's.
244 The affected files are lib/silccore/id.[ch] and other files
245 around the tree using these routines.
247 * Removed the ID length arguments in server from various
248 silc_server_send_notify_* routines -> they are not needed
251 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
253 * Fixed memory leak in silc_encode_pem_file in the file
254 lib/silcutil/silcutil.c.
256 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
258 * Check minor version as well in the SKE. Affected files are
259 silcd/protocol.c and lib/silcclient/protocol.c.
261 * Added --identifier option to the server so that an identifier
262 can be when creating the public key for the server. Affected
263 file is silcd/silcd.c.
265 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
266 lib/silccrypt/silcpkcs.c.
268 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
270 * Register default ciphers and stuff when using -C option with
271 the server. Affected file sildc/silcd.c.
273 * Put back the servers public key filename format, it is better
274 than the new one. For now, the client keys are saved with the
275 new filename format. The affected file silc/client_ops.c.
277 * Implemented the Cipher API for the rest of the ciphers that
278 did not implement it or implemented it the wrong way.
280 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
282 * Register default ciphers and stuff when using the -S option
283 in the client. Affected file silc/silc.c. Same also when
284 creating new key pair with -C option.
286 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * Fixed the silc_verify_public_key client operation function to
289 save the public keys differently. The fingerprint is now
290 used as filename and not the hostname. This way also the
291 client keys are saved uniquely and not with hostnames. The
292 affected file is silc/client_ops.c.
294 * Trimmed the silc_hash_fingerprint function to remove extra
295 whitespaces from the end of the fingerprint. The affected
296 file is lib/silccrypt/silchash.c.
300 * Added silc_cipher_register_default function to register all
301 default ciphers. It can be used when configuration files
302 does not exist and the application does not want any specific
303 ciphers in any specific order.
305 The SilcDList is now used as silc_cipher_list dynamically
306 allocated cipher list. Removed the static list all together
307 and now all ciphers must be allocated to the dynamic list.
308 The silc_cipher_alloc routine was changed to check only the
311 All silc_cipher_* routines that used to return int returns
314 The affected files lib/silccrypt/silccrypt.[ch].
316 * The same thing was done to silc_hash_* as for silc_cipher_*
317 routines. Affected files lib/silccrypt/silchash.[ch].
319 * The same thing was done to silc_pkcs_* as for silc_cipher_*
320 routines. Affected files lib/silccrypt/silcpkcs.[ch].
321 Added also silc_pkcs_[un]register[_default] functions.
322 Removed the data_context from the PKCS API.
324 * Added silc_hmac_register_default function to register default
325 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
326 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
327 to unregister all hmacs at once.
329 * Register the default ciphers, hash functions, PKCSs and HMACs
330 if client's configuration file does not exist. The affected
333 * The client did not load the hash functions from the SIM
334 modules at all. Added support for this. Affected file is
337 * When decoding public key with silc_pkcs_public_key_decode, check
338 the supported algorithm only if PKCS are registered. Affected
339 file lib/silccrypt/silcpkcs.c. The same was done with the
340 silc_pkcs_private_key_decode.
342 * Fixed the SILC List routines to keep the list always in order.
343 It used to change the list's order when traversing the list but
344 not it preserves the order. Affected file lib/trq/silclist.h.
346 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * Added the client library to use the SilcSocketConnection's
349 reference counter (by silc_socket_dup) to prevent the bug that
350 the socket object may be freed underneath async operation.
352 * The name resolv library checking fixes in the configure.in.pre.
355 * Created new version of the protocol drafts for future
356 development. The -03 drafts are the ones that will be changed
357 in the trunk now and the -02 will remain as they are.
359 * Send list of CUMODE notifys to the router when announcing
360 the channel users to the router. Affected file silcd/server.c.
361 If the router receiving channel founder CUMODE for a channel
362 that already has channel founder it will send CUMODE notify
363 to the sender to remove the channel founder rights from the
364 announced client. Affected file silcd/packet_receive.c.
366 * The CUMODE notify may now use Server ID as well as the entity
367 who changes the mode. Updated protocool specs.
369 * Updated INSTALL and README files.
371 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
373 * New web pages in the http://silc.pspt.fi. The pages was
378 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
380 * Implemented the [DenyConnectin] config section in the server.
381 Added silc_server_config_denied_conn to check whether incoming
382 connection is denied. Affected file silcd/serverconfig.[ch].
384 * Do not check the ports when checking the incoming configuration
385 data if the port is 0, meaning any. Affected file is
386 silcd/serverconfig.c.
388 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
390 * Fixed buffer overflow in silc_string_compare in the file
391 lib/silcutil/silcutil.c.
393 * Fixed double free in silc_server_command_leave in the file
396 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
398 * Fixed the version checking in the server. Affected file is
401 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
403 * Fixed the configuration data fetching when accepting new
404 connections in the server. Affected file silcd/server.c.
406 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
408 * Added `sender_entry' argument to the function
409 silc_server_packet_relay_to_channel so that we can check
410 whether some destination actually belongs to the same route
411 the sender belongs (ie, we must not resend the packet to the
412 sender). Affected file silcd/packet_send.[ch].
414 * Added `servername' field to the SilcClientEntry in the server
415 to hold the name of the server where client is from. Affected
416 file is silcd/idlist.h.
418 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
420 * Moved the channel message encrypting in the router betwen
421 router connections from silc_server_channel_message to the
422 silc_server_packet_relay_to_channel since we want to check
423 whether we have anybody channel before encrypting anything.
424 Affected files silcd/packet_[receive/send].c.
426 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
428 * Fixed the [AdminConnection] server config section to support
429 multiple entries. Affected file silcd/serverconfig.c.
431 * Added support into the server to check the validity of the
432 incoming connection before executing any KE or authentication
435 * The connection configuration is now saved to the KE and
436 connection auth protocol contexts and not fetched anymore in
437 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
439 * The local hosts listenning address and port is also resolved
440 now when starting the server. We want to have the socket object
441 to include the real address and port for the listener. Added
442 new function silc_net_check_local_by_sock into the files
443 lib/silcutil/silcnet.[ch].
445 * Fixed a broadcast bug in server -> do not broadcast if we
448 * Fixed a routing bug. Do not route broadcast packets ever.
449 Broadcast packets must be processed always and not routed since
450 they may be destined to some other host than yourself and thus
451 would get routed without no good reason. Affected file is
454 * Added function silc_server_config_is_primary_route to check
455 whether primary router connection has been configured (a router
456 configuration that we are initiating). If there is not, we
457 will assume that there is only two routers in the SILC network
458 and we will use the incoming router connection as our primary
459 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
461 * Changed the order of the broadcasting. Broadcast _after_ the
462 packet has been processed not before. Affected file is
465 * Fixed a [ClientConnection] parsing bug. The port was never
466 parsed correctly thus resulting to port 0. Affected file
467 silcd/serverconfig.c.
469 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
470 argument and did not set the broadcast packet flag. Affected
471 file silcd/packet_send.c. Fixed same bug in the function
472 silc_server_send_notify as well.
474 * If we receive NEW_ID packet for our own ID in the server, ignore
477 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Removed the nickname from the Private Message Payload.
482 Updated the code and the protocol specs.
484 * Updated protocol specs for submitting to the IETF.
486 * Tweaked the Random Number Generator a bit. Affected file
487 lib/silccrypt/silcrng.c. Exported a new function
488 silc_rng_[global]_add_noise which can be used to add more
491 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Do not parse packets with different timeout when protocol
494 is active -> may cause problem with rekey. Affected file
497 * When server receives signoff notify it must not create
498 new channel key if the client is on any channels since the
499 sender of the signoff notify will create it.
501 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
503 * Added printing of error messages during SKE protocol from the
504 failure packet sent by server during SKE. Affected file
507 * Removed the client's failure_callback handling with timeout
508 and handle it immediately when received.
510 * The SKE library returned wrong type in SUCCESS and FAILURE
511 packets. They must be 32 bit MSB not 16 bit MSB.
513 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
515 * Ok, rewrote the logic of the re-key and now it seems to work.
516 I tested it on high traffic with frequent re-keys without
517 problems. Added hmac_receive (and renamed hmac to hmac_send)
518 in SilcClientConnection in lib/silcclient/client.h and
519 in SilcIDListData in silcd/idlist.h. Also, removed the
520 SilcPacketParserContext's cipher and hmac fields as they are
521 not needed anymore and actually caused some problems when
522 the ciphers and hmac's changed underneath the packet parser.
524 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
526 * If re-key protocol is active then process the incoming packets
527 synchronously since we must assure that icoming packets encrypted
528 with the old key is processed before the new keys is set to
529 use. This is true other packets than for REKEY packets.
530 Affected file silcd/server.c. The same was done to client library
531 as well, affected file lib/silcclient/client.c.
533 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
535 * Fixed bug in client and server to accept the force send if
536 the packet is send from silc_[server/client]_packet_process
537 function. Otherwise the packets are never delivered, oops.
539 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
541 * Disable force sending of packets when REKEY protocol is active.
542 We must assure that no packet is sent directly when rekey is
543 performed. All packets must be sent through packet queue.
544 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
545 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
546 function is silc_[server/client]_packet_send_real to check
549 * Replaced the SIM paths from example config files to
550 /usr/local/modules. Also, make install creates now
551 /usr/local/silc/logs directory to hold all the SILC server
554 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

561 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
563 * Fixed the make install.
565 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
567 * When MAC computation fails the silc_packet_decrypt returned 0
568 even though it was supposed to return -1. Fixed this. The
569 affected file is lib/silccore/silcpacket.c.
571 * Do not replace the config files in /etc/silc (in make install)
572 if they already exist. Affected file ./Makefile.am.
574 * Do not send re-key packets immediately but through packet queue.
575 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
577 * Changed silc_net_check_host_by_sock to return FALSE if the
578 IP/DNS could not be resolved. Though, it returns the IP address
579 now even if it could not resolve it (but returns also FALSE).
580 Affected file lib/silcutil/silcnet.[ch].
582 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
584 * Added silc_pkcs_decode_identifier to decode the public key's
585 identifier. Affected file lib/silccrypt/silpkcs.[ch].
586 Added also silc_pkcs_free_identifier. Added also new context
587 SilcPublicKeyIdentifier.
589 * Added -S option to the silc client. It is used to dump the
590 contents of the specified public key file.
592 * Changed the PKCS api to return the public key length when
593 setting the public key.
595 * Fixed a fatal bug in the public and private key file loading.
596 Affected file lib/silccrypt/silcpkcs.c.
598 * Execute the packet parsing for client with zero (0) timeout
599 if the protocol is active. Affected file silcd/server.c.
601 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
603 * Made the key generation options to the silcd program. Added
604 -C option, equivalent to client's option.
606 * Added new [ServerKeys] config section to the server. It
607 configures the server's public and private key.
609 * Defined generic Public Key Payload into the protocol
610 specification to send specific type of public keys and
613 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
614 public key or certificate.
616 * Implemented the GETKEY command to the server and to the
617 client library and on user interface.
619 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
621 * Made preliminary `make install' work.
623 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
625 * Added SilcServerRekey context into silcd/idlist.h.
627 * Added the PFS support as defined in the specification to the
628 SKE protocol. Affected files lib/silcske/*.c.
630 * Added `ske_group' field to the SilcServerRekey context to hold
631 the number of the SKE group that is used with PFS in re-key.
632 Affected file silcd/idlist.h.
634 * Added PFS re-key support to the server. Affected file is
637 * Added silc_protocol_cancel to cancel execution of the next
638 state of the protocol. Affected file is
639 lib/silccore/silcprotocol.[ch].
641 * Added the re-key support with and without PFS to the client
642 library. Re-key is performed once in an hour, by default.
644 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
645 Added silc_client_rekey_callback and silc_client_rekey_final.
646 Affected files are lib/silcclient/protocol.[ch] and
647 lib/silcclient/client.[ch].
649 * Removed the `hmac_key' and `hmac_key_len' fields from the
650 SilcClientConnection structure; not needed. Affected file is
651 lib/silcclient/client.h.
655 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
657 * Do not ask whether user wants to use the negotiated private key
658 for private messages, just use it. Affected file is
659 silc/local_command.c.
661 * Added `send_enc_key' and `enc_key_len' fields to the
662 SilcIDListData structure since they are needed in the re-key
663 phase. Affected file is silcd/idlist.[ch].
665 * Implemented the simple re-key protocol into the server.
666 Affected files silcd/server.c and silcd/protocol.[ch]. The
667 re-key will be performed once in an hour, by default.
669 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
670 Added silc_server_rekey, silc_server_rekey_callback and
671 silc_server_rekey_final.
673 * Removed Tunneled flag from the protocol. Updated the code
674 and the specifications.
676 * Adde `pfs' field to the SilcIDListData to indicate whether
677 the PFS is to be performed in the re-key. Affected file is
680 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
682 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
683 int64 of at least the xintXX size. If void * is less that 4
684 bytes uint32 * will be used. Defined bool as boolean.
686 * Changed _ALL_ unsigned long and unsigned int to uint32,
687 unsgined short to uint16 in the source tree.
689 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
690 not handle clients that has entry->data.registered == FALSE.
691 They are not in the network anymore. Affected file is
694 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
696 * Implemented the sending of the SERVER_SIGNOFF notify in the
697 server. Affected file is silcd/server.c.
699 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
700 Added also silc_notify_payload_encode_args into the
701 lib/silccore/silcnotify.[ch].
703 * Implemented ther SERVER_SIGNOFF notify handling in the server.
704 Affected file silcd/packet_receive.c.
706 * Implemented the SERVER_SIGNOFF notify handling in the client
707 library. Affected file lib/silcclient/client_notify.c. Also,
708 implemnted the printing of the SERVER_SIGNOFF info to the
709 application. Affected file silc/client_ops.c.
711 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
712 if the deleting was successful. Affected file silcd/idlist.[ch].
714 * Added support for public key authentication in the connection
715 authentication protocol in the client library. Affected file
716 lib/silcclient/protocol.c.
718 * Changed the server's silc_idlist_get_clients_by_* interface
719 to support already allocated array so that new entries may be
720 added to pre-allocated array. Affected file silcd/idlist.[ch].
721 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
724 * All command reply functions in the server now calls the
725 pending command callback even if error occured. This way the
726 error will be delivered to the client as well. Affected files
727 silcd/command.c and silcd/command_reply.c.
729 * Fixed INFO command to return local server's info if no server
730 was provided. Affected file lib/silcclient/command.c.
732 * Removed RESTART command for good. Updated the code and the
735 * Rewrote parts of the task system. It is a bit simpler now.
736 Removed unsued task priorities. The affected files are
737 lib/silcutil/silctask.[ch].
739 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * Moved the USERS printing from the library to the application.
742 Affected files lib/silcclient/command.c and silc/client_ops.c.
744 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
748 * Added channel key re-key support. The re-key is perfomed
749 only by the router and is done once in an hour. Added `rekey'
750 field to the SilcChannelEntry in the server. Affected files
751 silcd/server.c and silcd/idlist.h.
753 * Added silc_task_unregister_by_context into the file
754 lib/silcutil/silctask.[ch].
756 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
758 * Added SILC_UMODE_GONE mode to indicate when the client is not
759 present in the SILC network. Added also support to the local
760 command AWAY that will set this mode. Added support of showing
761 "xxx is gone" in WHOIS command. The USERS command shows the
764 * Fixed setting server and router operator privileges in the
765 server's UMODE command. Affected file silcd/command.c.
767 * Merged the SKE KE1 and KE2 payloads into one payload. The
768 new KE payload is equivalent to the old KE2 payload.
770 Cleaned up the SKE Start Payload parsing. It now uses the
771 simple buffer unformatting to do the parsing. A lot faster
774 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
775 to the SKE that is used to indicate whether both of the SKE
776 parties should perform authentication. By default only the
777 responder performs authentication. By setting this flag also
778 the initiator must do authentication. By default it is unset
779 since in normal SKE case, client to server connection, only
780 the responder should do authentication. When doing SKE between
781 two clients both should perform authentication. Updated the
782 code and the protocol specs.
784 * A little fix to IDENTIFY command in the server. Search the
785 client first by hash not nickname. Affected file is
788 * Fixed the silc_client_close_connection to support closing
789 the client to client connections wihtout deleting too much
790 data. Affected file lib/silcclient/client.c.
792 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
793 are received if protocol used to be active but is not anymore
794 the application would crash due to NULL pointer dereference.
795 Affected files silcd/server.c and lib/silcclient/client.c.
797 * Added `hash' field to the SilcClientConnection to include
798 the hash function negotiated in the SKE protocol.
800 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
801 to set the channel founder authentication data. A client can
802 claim the founder rights later by providing the authentication
803 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
804 This way the channel founder can regain the channel founder
805 privileges even it is left the channel. This works only on
806 local server and the client must be connected to the same
807 server to be able to regain the founder rights. Updated the
808 protocol specs accordingly.
810 Added support to the CMODE command in the client to set the
811 founder auth data. Read the README to see how to set it.
813 Added support to the CUMODE command to claim the founder
814 rights. Read the README to see how to do it.
816 Added support for the founder authentication to the Channel
817 Entry in the server. Affected file silcd/idlist.h.
819 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
820 server's CMODE command. Affected file silcd/command.c.
822 * Added the following new functions into lib/silccore/silcauth.[ch]:
823 silc_auth_get_method and silc_auth_get_data.
825 * The server now saves the remote hosts public key to the
826 SilcIDListData pointer. Affected file silcd/protocol.c.
828 * The normal server now does not remove the channel entry from
829 the cache if the founder authentication data is set. It used
830 to remove it if the founder was the last one on the channel on
831 the server and left the channel. The auth data is saved and
832 if the channel is re-joined later the old entry is used with
833 the old auth data. Affected files silcd/command_reply.c and
836 * Removed the `pkcs' field from the SilcIDListData structure
837 in the server; it is not used. Affected file silcd/idlist.h.
839 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
841 * Fixed packet processing on slow links. Partial packets were
842 never re-processed because the incoming data buffer was cleared
843 by the application. Application must not directly clear the
844 sock->inbuf, the packet processing routines handle it. Fixed
845 this in client library and in server.
847 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
849 * Fixed the WHOIS and IDENTIFY send reply function to really
850 check whether to send list or just one entry. Affected file
853 * Cleaned up the LEAVE command's channel key distribution. The
854 affected file silcd/command.c.
856 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
857 can enforce the channel mode as well. In that case the ID
858 includes the ID of the server. The code now enforces the
859 mode change if the router have different mode than the server.
861 * The notify client operation with CMODE_CHANGE notify can now
862 return NULL client_entry pointer if the CMODE was not changed
863 by client. Application must check for this.
865 * Added <Server ID> argument to INFO command to support server
866 info fetching by Server ID.
868 * Added silc_server_announce_get_channel_users to get assembled
869 packets of channel users of the specified channel. Affected
870 file silcd/server.[ch].
872 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
873 was freed underneath the ID Cache.
875 * Re-announce clients when the server received CHANNEL_CHANGE
876 notify from the router. Affected file silcd/packet_send.c.
878 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
880 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
881 crashed since it did not handle the fact that there is no cipher
882 called "3" and didn't check the error condition. Now fixed.
884 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
885 flag. It can be used to send message requests.
887 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
889 * Implemented the RESTART command in the client.
891 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
892 notice type messages. Added notice printing to the user
895 * The channel keys are not re-generated if the channel's mode
896 is PRIVKEY, ie private key on the channel exists. Affected
897 files silcd/server.c and silcd/command.c.
899 * Fixed a little bug in channel message delivery when channel
900 private keys are set in the server. Affected file is
903 * Changed the setting on channel->on_channel = TRUE from the
904 silc_client_save_channel_key to the JOIN command reply. The
905 key payload is not received if the private channel key is set.
906 Affected file lib/silcclient/command_reply.c and the
907 lib/silcclient/client_channel.c.
909 * When the CMODE_CHANGE notify is sent and the channel private
910 key mode is removed the channel key must be re-generated in
911 other cells as well. Added this support for the router in the
912 silcd/packet_receive.c.
914 * Added new local command NOTICE to send notice message on
915 channel. Affected file silc/local_command.[ch].
917 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
919 * Added new local command ME to the client. It is used to send
920 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
921 some action. Affected file silc/local_command.[ch].
923 * Changed channel_message and private_message client operations
924 to deliver the message flags to the application. Added also
925 the `flags' arguments to the silc_client_send_channel_message
926 and silc_client_send_private_message functions. Affected file
929 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
931 * Redefined the Private Message Payload to support private message
932 keys and to support the new private message flags. Updated
933 the protocol specs. Flags makes it possible to have for example
936 * Added new type SilcPrivateMessagePayload and defined an API
937 for it in the lib/silcclient/silcprivate.[ch].
939 * Tested private message private keys successfully. Tested the
940 private message key set, unset and list commands with the new
943 * Redefined the Channel Message Payload to include the channel
944 message flags (equal with private message flags) to support
945 for example CTCP style messages.
947 * Defined some of the message (for channel and private message)
948 flags. Updated the protocol specs and added the flags to the
949 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
951 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
953 * Added SilcKeyAgreementStatus type to the key agreement routines
954 to indicate the current status and error if one occured.
955 The status types are defined in the lib/silcclient/silcapi.h.
957 * Added new local command KEY that is used to set and unset private
958 keys for channels, set and unset private keys for private messages
959 with remote clients and to send key agreement requests and
960 negotiate the key agreement protocol with remote client. The
961 key agreement is supported only to negotiate private message keys,
962 it currently cannot be used to negotiate private keys for channels,
963 as it is not convenient for that purpose.
965 * Fixed a minor pending callback setting bug in the function
966 silc_client_get_client_by_id_resolve, now the function works.
967 Affected file lib/silcclient/idlist.c.
969 * Added function silc_net_get_local_port to get local bound
970 port by socket. Added to lib/silcutil/silcnet.[ch].
972 * Added `sockets' and `sockets_count' fields to the SilcClient
973 object. They hold the sockets of the listenning sockets in
974 the client. Listenning sockets may be for example the key
975 agreement server. Affected file lib/silcclient/client.[ch].
976 Added functions the silc_client_add_socket and the
977 silc_client_del_socket. They are exported to the application
980 * Added ~./silc/clientkeys to support other client's public keys.
982 * Renamed verify_server_key client operation to verify_public_key
983 and added one argument to indicate the type of the connection
984 (server, client etc.).
986 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
988 * Added silc_server_connection_auth_request to handle the
989 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
990 silcd/packet_receive.[ch].
992 * Added silc_server_send_connection_auth_request into the
993 silcd/packet_send.c to send the connection auth request packet.
995 * Cleaned up the silcd/protocol.c a bit and fixed some memory
998 * Fixed the public key authentication in responder side in the
999 server. The `auth_data' pointer includes the SilcPublicKey
1000 not the path to the public key. Affected file silcd/protocol.c.
1002 * Implemented the public key authentication in the initiator side
1003 in the server. Affected file silcd/protocol.c.
1005 * Removed the [RedirectClient] config section from the server
1006 configuration. Is not needed and I don't want to implement it.
1008 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Cleaned up the CMODE command in the server. It now works
1011 correctly and supports all the modes defined in the protocol.
1012 Affected file is silcd/command.c.
1014 * Added `hmac_name' field to the SilcChannelEntry in the server
1015 to hold the default HMAC of the channel. It can be set when
1016 creating the channel (with JOIN command). Affected files
1019 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1020 type to indicate the change of the current cipher and hmac
1021 on the channel. Client can safely ignore the <cipher> argument
1022 (if it chooses to do so) since the CHANNEL_KEY packet will
1023 force the channel key change anyway. The <hmac> argument is
1024 important since the client is responsible of setting the new
1025 HMAC and the hmac key into use.
1027 * Fixed the CMODE command in the client library as well.
1029 * Tested CMODE command in router environment successfully.
1031 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1033 * Show the version of the remote client (or server) when connecting
1034 to the server. It is logged to the log file. Affected file
1035 is silcd/protocol.c.
1037 * Fixed the KILLED notify handling in the client library. The
1038 client must be removed from all channels when receiving the
1041 Also, do not remove the client entry when giving the KILL
1042 command but when the KILLED notify is received.
1044 * Removed silc_idlist_find_client_by_nickname from the server.
1045 Not needed anymore. Affected files silcd/idlist.[ch].
1047 * Implemented the CHANNEL_CHANGE notify type handling to the
1048 server. Affected file silcd/server.c.
1052 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Added silc_server_send_notify_invite to send the INVITE
1055 notify between routers.
1057 * Implemented the INVITE command correctly to the server.
1059 * Implemented the INVITE notify type handling in the server.
1061 * Implemented the INVITE command to the client library and on the
1064 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1066 * Added function silc_server_get_client_resolve to find the
1067 client entry by ID from all ID lists and then resolve it
1068 (using WHOIS) if it cannot be found. Affected file is
1071 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1073 * Implemented the BAN command to the client library.
1075 * The JOIN command in the server now checks the invite list
1078 * Changed the silc_command_reply_payload_encode_va and the
1079 silc_command_payload_encode_va to support that if argument is
1080 NULL it ignores and checks the next argument. Affected file
1081 lib/silccore/silccommand.c.
1083 * Added silc_server_send_notify_ban to send the BAN notify
1084 type between routers.
1086 * Chaned the silc_notify_payload_encode to support that if
1087 argument is NULL it ignores and checks the next argument.
1088 Affected file lib/silccore/silcnotify.c.
1090 * Tested ban lists in router environment successfully.
1092 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1094 * Implemented BAN command to the server, in silcd/command.[ch].
1096 * Removed the BAN and INVITE_LIST modes from the CMODE command
1099 * Added function silc_string_match to regex match two strings.
1100 Affected files lib/silcutil/silcutil.[ch].
1102 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Redefined parts of the SilcChannelEntry in the server to support
1105 the new ban and invite lists.
1107 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * Redefined the INVITE command. The same command can be used to
1110 invite individuals to the channel but also to manage the invite
1111 list of the channel (to add to and remove from the invite list).
1112 Updated the protocol specs.
1114 * Added new command SILC_COMMAND_BAN that can be used to manage
1115 the ban list of the channel. Updated the protocol specs.
1117 * Removed the channel modes: the SILC_CMODE_BAN and the
1118 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1119 in the CMODE command. The equivalent features are now available
1120 using INVITE and BAN commands. Updated the protocol specs.
1122 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1123 in the network about change in the current ban list. The notify
1124 type is not used by the client.
1126 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1127 support the invite lists.
1129 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1131 * Added new function silc_string_regexify that converts string
1132 including wildcard characters into regex string that can
1133 be used by the GNU regex library. Added into the file
1134 lib/silcutil/silcutil.[ch].
1136 Added silc_string_regex_combine to combine to regex strings
1137 into one so that they can be used as one regex string by
1138 the GNU regex library. Added into the file
1139 lib/silcutil/silcutil.[ch].
1141 Added silc_string_regex_match to match two strings. It returns
1142 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1144 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1146 * Imported GNU regex to the soruce tree into lib/contrib.
1147 Fixed some compiler warning from the regex.c.
1149 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1151 * Fixed MOTD command in the server to work in router environment.
1153 * Fixed the MOTD command in the client library to support
1154 the server argument in the command.
1156 * Added `nickname_len' argument to the silc_idlist_add_client
1157 in the server, as the `nickname' argument may be binary data
1160 * Added silc_idlist_get_channels to return all channels from
1163 * Implemented LIST command to the server. Affected file is
1166 * Implemented the LIST command to the client library and on the
1169 * Added [<user count>] argument to the LIST command reply.
1170 With private channels the user count is not shown.
1172 * Updated TODO and README.
1174 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1176 * The client entry's data.registered must be TRUE even with
1177 global client entry on global client list. The data.registered
1178 is used to check whether the client is anymore in the network,
1179 for example with WHOWAS command so it must be valid.
1181 * Fixed the WHOWAS command in the server. It now actually works
1182 in router environment. Added function into silcd/command_reply.c
1183 silc_server_command_reply_whowas_save.
1185 * Added silc_idlist_purge function to the silcd/idlist.c
1186 to periodically purge the ID Cache.
1188 * Fixed INFO command in the server. It works now in router
1189 environment. Added <server name> argument to the INFO command
1190 reply. Updated the protocol specs.
1192 * Fixed minor bug in silc_idcache_purge to not purge if the
1193 expire value is zero.
1195 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1196 they were buggy because of the WHOWAS information.
1198 * Fixed local command MSG to handle the async resolving of
1199 the remote client properly. It used to fail the first MSG.
1200 Affected file silc/local_command.c.
1202 * Added `data_len' field to SilcIDCache context.
1204 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1206 * Update TODO. Todo in commands in the server.
1208 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1210 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1211 used by routers as broadcast packet to inform other routers
1212 about the changed user mode.
1214 Implemented the notify handling in the server. Affected file is
1215 silcd/packet_receive.c. Added the function
1216 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1218 * Added new generic Channel Payload and deprecated the New Channel
1219 Payload. The New Channel Payload is now the generic Channel
1222 * Added new argument `mode' to the silc_server_send_new_channel
1223 as it is required in the Channel Payload now.
1225 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1226 and created a new and real SilChannelPayload to represent the
1227 new generic Channel Payload. Implemented the encode/decode
1228 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1230 * Added silc_server_get_client_channel_list to return the list
1231 of channels the client has joined for WHOIS command reply.
1232 Affected file silcd/server.[ch].
1234 * Implemented the channel list sending in the WHOIS command reply
1235 in server and in the client.
1237 Implemented the channel list displaying on the user interface
1238 as well. Affected file silc/client_ops.c.
1240 * Added silc_channel_payload_parse_list to parse list of Channel
1241 Payloads. It returns SilcDList list of SilcChannelPayloads.
1242 Client for example can use this function to parse the list of
1243 channels it receives in the WHOIS command reply. The caller
1244 must free the list by calling silc_channel_payload_list_free.
1245 Affected files lib/silccore/silcchannel.[ch].
1247 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1249 * Added one new argument <user mode> to the WHOIS command reply
1250 to return the mode of the user in SILC. Updated the protocol
1253 Implemented it to the server and client.
1255 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1257 * Fixed the mode printing on the user interface on joining.
1258 Affected file silc/client_ops.c.
1260 * Implemented the UMODE command and user modes in general to the
1261 client library and to the user interface.
1263 * Implemented the UMODE command to the server.
1265 * The server now sends UNKNOWN_COMMAND error status if client sends
1266 unknown command. Affected file silcd/command.c.
1268 * All server commands now handle the command identifier the right
1269 way when sending the command reply to the client. The client can
1270 use to identify the command replies with the identifier.
1272 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1274 * Added silc_server_get_client_route to resolve the route to
1275 the client indicated by the client ID. Affected file is
1278 * Added silc_server_relay_packet as general function to relay
1279 packet to arbitrary destination. This deprecates functions
1280 like _send_private_message_key, _relay_notify etc. Affected
1281 file is silcd/packet_send.[ch].
1283 Removed silc_server_send_key_agreement,
1284 silc_server_send_private_message_key and
1285 silc_server_packet_relay_notify functions from the file
1286 silcd/packet_send.[ch].
1290 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1291 server. Affected file silcd/packet_receive.[ch].
1293 * Implemented the KILL command to the client. Implemented the
1294 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1295 Affected files lib/silcclient/command[_reply].c and
1296 lib/silcclient/client_notify.c. Implemented the KILL notify
1297 printing in the user inteface.
1299 * Fixed a lot silc_parse_nick memory leaks from the client
1300 library in the file lib/silcclient/command.c.
1302 * Changed the silc_server_send_notify_on_channels's `sender'
1303 argument from SilcSocketConnection to SilcClientEntry to
1304 check the sender as entry and not as connection object and not
1305 to send to the client provided as argument. The affected file
1306 is silcd/packet_send.[ch].
1308 * The notify packets that are destined directly to the client used
1309 to not to be processed by the server. Now changed that and the
1310 server processes all notify packets. After relaying the packet
1311 to the client the notify packet is processed in the server.
1313 * The silc_server_free_client_data now checks whether there is
1314 pending outgoing traffic for the client and purges the data to
1315 the network before removing the client entry.
1317 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1319 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1320 an client is killed from the SILC Network. Updated the protocol
1323 Added new function silc_server_send_notify_killed to the
1324 silcd/packet_send.[ch].
1326 * Added function silc_server_packet_relay_notify to relay notify
1327 packets that are destined directly to a client. In this case
1328 the server does not process the notify packets but merely relays
1329 it to the client. Affected file silcd/packet_send.[ch].
1331 Added also silc_server_packet_process_relay_notify to check
1332 whereto relay the notify. Affected file is
1333 silcd/packet_receive.[ch].
1335 * Implemented the KILL command to the server.
1339 * Added the backup schema desgined last fall to the protocol
1340 specs for everyone to see. The specification is in the
1341 *-spec-xx.txt draft and the packet type definitions for the
1342 backup routers is in *-pp-xx.txt draft. Thusly, added also
1343 new packet type SILC_PACKET_CELL_ROUTERS.
1345 * A big security problem in the implementation discovered. The
1346 signoff of an client did not cause new channel key generation
1347 which it of course should've done. The channel keys must be
1348 always re-generated when client leaves (or signoffs) the channel.
1349 The silc_server_remove_from_channels funtion now handles
1350 the channel key re-generation.
1352 * Added `sender' argument to the silc_server_send_notify_on_channels
1353 to not to send the client provided as argument. Affected file
1354 silcd/packet_send.[ch].
1356 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1358 * Implemented OPER and SILCOPER commands into the server and
1361 * Added silc_auth_verify and silc_auth_verify_data to verify
1362 the authentication directly from the authentication payload.
1363 It supports verifying both passphrase and public key based
1364 authentication. Affected file lib/silccore/silcauth.[ch].
1366 * Added `hash' field to the SilcIDListData structure. It is the
1367 hash negotiated in the SKE protocol. Affected file is
1370 * Slight redesigning of the SilcAuthPayload handling routines.
1371 Do not send SilcPKCS but SilcPublicKey as argument.
1373 * Implemented the public key authentication support to the
1374 serverconfig. The public key is loaded from the provided path
1375 and saved as authentication data to void * pointer. Thus,
1376 changed the unsigned char *auth_data to void *auth_data;
1378 * Fixed SHUTDOWN command to send the reply before the server
1379 is shutdown. :) Affected file silcd/command.c.
1381 * Fixed fatal bug in CONNECT command. The hostname was invalid
1382 memory and server crashed. Affected file silcd/command.c.
1384 * Fixed fatal bug in CLOSE command. The server_entry became
1385 invalid but was referenced later in the command. Affected file
1388 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * Fixed fatal bug in failure packet handling. Server ignored
1391 the failure and thus crashed when it came.
1395 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1398 that the command may be executed only once in (about) 2 seconds.
1399 The old SILC_CF_LAG flag is same but allows command bursts up
1400 to five before limiting.
1402 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1403 server code. Various commands now includes the CF_LAG_STRICT
1404 flag to disallow any kind of miss-use of the command.
1406 * Fixed the silc_buffer_unformat to not to allocate any data
1407 if the length of the data is zero. It used to allocate the
1408 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1410 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Changed the format of AdminConnection configuration section
1413 in the server. Added username of the admin to the format.
1414 Affected files silcd/serverconfig.[ch].
1416 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1417 to return admin configuration data by host, username and/or
1420 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1422 * Implemented WHOWAS command to the server. Added the functions:
1424 silc_server_command_whowas_parse,
1425 silc_server_command_whowas_send_reply,
1426 silc_server_command_whowas_from_client and
1427 silc_server_command_whowas_from_server
1429 * Added <Client ID> argument to the WHOWAS command reply. Updated
1430 the protocol specs accordingly.
1432 * Implemented WHOWAS command and command_reply to the client
1435 Implemented the WHOWAS printing on the user interface.
1437 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1439 * Added new argument to the WHOWAS command reply, the real name.
1440 It is an optional argument. Updated the protocol specs.
1442 * Added SilcIDCacheDestructor callback that is registered when
1443 the SilcIDCache is allocated. The callback is called when
1444 an cache entry in the ID Cache expires, or is purged from the
1445 cache. Added into lib/silccore/idcache.[ch].
1447 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1448 to destruct the client entries when the cache entry expires.
1449 Other ID Cache's in server and in the client library ignores
1452 * If the ID Cache entry's `expire' field is zero then the entry
1453 never expires. Added boolean `expire' argument to the
1454 silc_idcache_add function in the lib/silccore/idcache.[ch].
1455 If it is TRUE the default expiry value is used.
1457 * Added silc_server_free_client_data_timeout that is registered
1458 when client disconnects. By default for 5 minutes we preserve
1459 the client entry for history - for WHOWAS command.
1461 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1463 * Added support to the server to enforce that commands are not
1464 executed more than once in 2 seconds. If server receives
1465 commands from client more frequently, timeout is registered
1466 to process the commands. Affected file silcd/command.c.
1467 Added new function silc_server_command_process_timeout.
1469 * Changed NICK_NOTIFY handling in client library to check that
1470 if the client's nickname was changed, so there is no need to
1471 resolve anything from the server.
1473 * Removed error printing from the WHOIS and IDENTIFY commands.
1474 If error occurs then it is ignored silently in the client library.
1475 The application, however, may map the received error to
1476 human readable error string. The application currently maps
1477 the NO_SUCH_NICKNAME error to string.
1479 * Made the command status message public to the application. Moved
1480 them from lib/silcclient/command_reply.c to
1481 lib/silcclient/command_reply.h. The application can map the
1482 received command status to the string with the
1483 silc_client_command_status_message function.
1485 * Added check to the server to check that client's ID is same
1486 as the Source ID in the packet the client sent. They must
1489 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1491 * Added dist-bzip hook to the Makefile.am to make bzip2
1492 compressed distributions.
1494 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1496 * Server now enforces the maximum length for the nickname and
1497 the channel as protocol specification dictates. 128 bytes for
1498 nickname and 256 bytes for channel name.
1500 * Moved the WHOIS printing to the application. The client libary
1501 does not print out the WHOIS information anymore, the application
1502 must do it. Renamed silc_client_command_reply_whois_print to
1503 the silc_client_command_reply_whois_save.
1505 The client's idle time is also sent to the application now, and
1506 the idle is shown on screen.
1508 * Added silc_client_command_reply_identify_save to save the
1509 received IDENTIFY entries.
1511 * Do not check for channel private keys in message sending and
1512 reception if the channel does not have the PRIVKEY mode set.
1513 Affected file lib/silclient/client_channel.c.
1515 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1517 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1518 just surfaced after chaning the JOIN procedure.
1520 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1522 * Added silc_client_get_clients_by_list to get client entries
1523 from Client ID list, that is returned for example by JOIN
1524 and USERS command replies. The application should use this
1525 function for example when JOIN command reply is received to
1526 resolve the clients already on the channel (library does not
1527 do that anymore as USERS command reply is not used in the JOIN
1528 procedure anymore). Affected files lib/silcclient/silcapi.h and
1529 lib/silcclient/idlist.c.
1531 * JOIN command reply and USERS command reply returns now SilcBuffer
1532 pointers instead of unsigned char pointers when returning
1533 the client list and mode list.
1535 * Added <Client ID> argument to the JOIN command reply, mainly
1536 for the server to identify for which client the command was
1537 originally sent. Updated protocol specs accordingly.
1539 * Added SilcDlist private_key pointer to the SilcChannelEntry
1540 in the client to support the channel private keys. Affected
1541 file is lib/silcclient/idlist.h.
1543 * Added SilcChannelPrivateKey argument to the function
1544 silc_client_send_channel_message so that application can choose
1545 to use specific private ke if it wants to. If it is not provided,
1546 the normal channel key is used, unless private keys are set.
1547 In this case the first (key that was added first) is used
1548 as the encryption key.
1550 * Implemented the support for channel private key handling.
1551 Implemented the following functions:
1553 silc_client_add_channel_private_key,
1554 silc_client_del_channel_private_keys,
1555 silc_client_del_channel_private_key,
1556 silc_client_list_channel_private_keys and
1557 silc_client_free_channel_private_keys
1559 Affected file lib/silcclient/client_channel.c.
1561 * Added the support for the private keys in the channel message
1562 sending and encryption and in the message reception and
1563 decryption. Affected funtions are
1564 silc_client_send_channel_message and silc_client_channel_message.
1566 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * Added SKE's key verify callback to the client library's
1569 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1571 * Removed the statement that server (or router) must send USERS
1572 command reply when joining to the channel so that the client
1573 knows who are on the channel. Instead, the client list and
1574 client's mode list is now sent in the JOIN command reply to the
1575 client who joined channel. This is better solution.
1577 * Added function silc_server_get_users_on_channel and function
1578 silc_server_save_users_on_channel to the silcd/server.[ch].
1580 * Removed function silc_server_command_send_users from the
1583 * Do not show topic on the client library anymore. The topic is
1584 sent in the command reply notify to the application and the
1585 application must show the topic now.
1587 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1589 * Added client searching by nickname hash into the IDENTIFY and
1590 WHOIS commands in the server as they were clearly missing from
1591 them. Affected file is silcd/command.c.
1593 * Fixed a bug in private message receiving in the client library.
1594 The remote ID was freed and it wasn't supposed, now it is
1597 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1599 * Minor fix to the channel payload; allocate the data area, as it
1600 needs to be of specific length.
1602 * If the key agreement port is zero then the operating
1603 system will define the bound port. Affected files are
1604 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1606 * Added new function silc_channel_payload_decrypt into the file
1607 lib/silccore/silcchannel.[ch].
1609 * Moved the channel message etc, check from silc_packet_decrypt
1610 to applications. The library calls now a generic
1611 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1612 when the packet is either normal or special. This was done to
1613 allow more wide range of checking that was not allowed when
1614 the code was in library. Now applications can do virtually any
1615 checks to the packet and return to the library the decision how
1616 the packet should be processed. Affected files are
1617 lib/silccore/silcpacket.[ch].
1619 Added silc_server_packet_decrypt_check to the server and
1620 silc_client_packet_decrypt_check to the client library.
1622 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1623 to send with specified source and destination information.
1625 * Channel message delivery between routers was broken after the
1626 channel key distribution was fixed earlier. The channel key
1627 was used be to distributed to other routers as well which is not
1628 allowed by the protocol. Now this is fixed and channel keys
1629 really are cell specific and the channel message delivery between
1630 routers comply with the protocol specification.
1632 * Fixed various commands in server to check also the global list
1633 for the channel entry and not just the local list. The affected
1634 file silcd/command.c.
1636 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1638 * Added assert()s to buffer formatting and unformatting routines
1639 to assert (if --enable-debug) when error occurs. Affected
1640 file: lib/silcutil/silcbuffmt.c.
1642 * Changed to auto-reconnect to check whether the remote host is
1643 router and register the re-connect timeout if it is. It used
1644 to check that whether we are normal server, but router must do
1645 auto-reconnect with another router as well. Affected file
1648 * Removed the [<key len>] option from CMODE command as the cipher
1649 name decides the key length, nowadays. See the defined ciphers
1650 from the protocol specification.
1652 * Added [<hmac>] option to the CMODE command to define the HMAC
1653 for the channel. Added SILC_CMODE_HMAC channel mode.
1655 * Added [<hmac>] option for the JOIN command so that user can
1656 select which HMAC is used to compute the MACs of the channel
1659 * Added Hmac field to the Channel Message Payload. The integrity
1660 of plaintext channel messages are now protected by computing
1661 MAC of the message and attaching the MAC to the payload. The
1662 MAC is encrypted. Now, it is clear that this causes some
1663 overhead to the size of the packet but rationale for this is that
1664 now the receiver can verify whether the channel message decrypted
1665 correctly and also when private keys are set for the channel the
1666 receiver can decrypt the packet with several keys and check from
1667 the MAC which key decrypted the message correctly.
1669 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1670 lib/silccrypt/silccipher.[ch].
1672 * Added silc_hash_len to return the digest length into the
1673 lib/silcrypt/silchash.[ch].
1675 * Rewrote parts of Silc Channel Payload interface in the
1676 lib/silccore/silcchannel.[ch]. The encode function now also
1677 encrypts the packet and parse function decrypts it.
1679 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1681 * Fixed a minor formatting bug in the SKE's key material processing.
1682 It actually might have processed the keys wrong way resulting
1685 * Redefined the mandatory HMAC algorithms and added new algorithms.
1686 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1687 and hmac-md5 truncated to 96 bits. The mandatory is now
1688 hmac-sha1-96. Rest are optional (including the one that used
1689 to be mandatory). Rationale for this is that the truncated HMAC
1690 length is sufficient from security point of view and can actually
1691 make the attack against the HMAC harder. Also, the truncated
1692 HMAC causes less overhead to the packets. See the RFC2104 for
1695 * Added new [hmac] configuration section. The SKE used to use
1696 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1697 is of course wrong. The official names that must be proposed in
1698 the SKE are the ones defined in the protocol specification
1699 (hmac-sha1-96 for example). The user can configure any hmac
1700 using any hash function configured in the [hash] section. At
1701 least, the mandatory must be configured.
1703 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1705 * Added HMAC list to the SKE proposal list. It has now both
1706 hash algorithm list and HMAC list. This makes the protocol
1707 incompatible with previous versions. The SKE now seems to work
1708 the way it is supposed to work, for the first time actually.
1710 * Defined plain Hash algorithms to the protocol specification.
1713 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Implemented support for key agreement packets into the server.
1716 Added functions silc_server_key_agreement and
1717 silc_server_send_key_agreement. Other than these functions,
1718 server has nothing to do with this packet.
1720 * Added support for private message key packets into the server.
1721 Added functions silc_server_private_message_key and
1722 silc_server_send_private_message_key.
1726 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1727 called in the protocol's final callback instead in the END
1728 protocol state. This makes a little more sense and in the same
1729 time in client we can use the same protocol routines for normal
1730 key exchange and to key agreement packet handling as well.
1732 * Added to both client's and server's KE protocol context the
1733 SilcSKEKeyMaterial pointer to save the key material. We will
1734 bring the key material to the protocol's final callback by doing
1735 this. The final callback must free the key material.
1737 * Added SKE's packet_send callback into client's KE protocol
1738 context so that the caller can choose what packet sending function
1739 is used. This way we can use different packet sending when
1740 doing normal SKE when doing key agreement packet handling (in
1741 the key agreement packet handling we do not want to encrypt
1744 * Implemented the responder side of the key agreement routines
1745 in the client. The client can now bind to specified port and
1746 accept incoming key negotiation. The key material is passed
1747 to the application after the protocol is over.
1749 * Implemented the processing of incoming Key Agreement packet
1750 in the client. Added function silc_client_key_agreement to
1753 * Implemented the intiator side of the key agreement routines
1754 in the client. The client can now initiate key agreement with
1755 another remote client. The key material is passed to the
1756 application after the protocol is over.
1758 * Created client_keyagr.c to include all the key agreement
1761 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1762 SILC_TASK_CALLBACK except that it is not static.
1764 * Created client_notify.c and moved the Notify packet handling
1765 from the client.[ch] into that file.
1767 * Created client_prvmsg.c and moved all private message and
1768 private message key routines from the client.[ch] into that file.
1770 * Create client_channel.c and moved all channel message and
1771 channel private key routines from the client.[ch] into that file.
1773 * Changed silc_client_get_client_by_id_resolve to resolve with
1774 WHOIS command instead of IDENTIFY command, in the file
1775 lib/silclient/idlist.c.
1777 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1779 * Implemented the SKE's responder side to the Client library.
1781 * When FAILURE is received to the protocol do not trust it
1782 blindly. Register a timeout to wait whether the remote closes
1783 the connection as it should do it, only after that process the
1784 actual failure. This was changed to both client and server.
1786 * Added client_internal.h to include some of the structures
1787 there instead of client.h in lib/silcclient/.
1789 * Added function silc_task_unregister_by_callback to unregister
1790 timeouts by the callback function.
1792 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1794 * Some "Incomplete WHOIS info" errors has been appearing on the
1795 log files. Took away the entry->userinfo check from WHOIS
1796 reply sending. The entry->userinfo is now " " if client did not
1797 provide one. I thought this was fixed earlier but something
1798 is wrong still. Let's see if the error still appears.
1800 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1802 * Fixed a minor bug in the login when the channel key is
1803 re-generated in the server. It used to generate the key in
1804 wrong order and thus caused problems in the channel traffic.
1806 * Fixed a minor bug in channel key distsribution after
1807 KICK command. The key was not sent to the router even though
1810 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1812 * Added silc_ske_process_key_material_data as generic routine
1813 to process any key material as the SILC protocol dictates. The
1814 function is used by the actual SKE library but can be used by
1815 applications as well. This relates to the private message keys
1816 and the channel private keys since they must be processed the
1817 same way the normal SILC session keys. The protocol dictates
1818 this. Affected files: lib/silcske/silcske.[ch].
1820 Added also silc_ske_free_key_material to free the
1821 SilcSKEKeyMaterial structure.
1823 * Defined silc_cipher_set_key function to set the key for
1824 cipher without using the object's method function. The affected
1825 files: lib/silccrypt/silccipher.[ch].
1827 * Implemented silc silc_client_add_private_message_key,
1828 silc_client_add_private_message_key_ske,
1829 silc_client_del_private_message_key,
1830 silc_client_list_private_message_keys and
1831 silc_client_free_private_message_keys functions in the
1834 Added functions silc_client_send_private_message_key to send
1835 the Private Message Key payload and silc_client_private_message_key
1836 to handle incoming Private Message Key payload.
1838 * Added Cipher field to the Private Message Key payload to set
1839 the cipher to be used. If ignored, the default cipher defined
1840 in the SILC protocol (aes-256-cbc) is used.
1842 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1844 * Removed lib/silcclient/ops.h file.
1846 Redefined parts of the SILC Client Library API. Created new
1847 file silcapi.h that deprecates the ops.h file and defines the
1848 published Client Library API. Defined also private message key
1849 API and channel private key API into the file.
1851 This is the file that the application must include from the
1852 SILC Client Library. Other files need not be included by
1853 the application anymore.
1855 * Added new key_agreement client operation callback and also
1856 defined the Key Agreement library API for the application.
1858 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1860 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1861 is used by clients to request key negotiation between another
1862 client in the SILC network. If the negotiation is started it
1863 is performed using the SKE protocol. The result of the
1864 negotiation, the secret key material, can be used for example
1865 as private message key.
1867 Implemented the Key Agreement payload into the files
1868 lib/silccore/silauth.[ch].
1870 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1872 * Redefined ciphers for the SILC protocol. Added some new ciphers
1873 and defined the key lengths for the algorithms. Changed the
1874 code accordingly. The default key length is now 256 bits.
1876 * Fixed SKE key distribution function silc_ske_process_key_material
1877 when the key length is more than 128 bits. The default key
1878 length in SILC is now 256 bits.
1880 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1881 to indicate unsupported algorithm.
1883 * Renamed rijndael.c to aes.c and all functions as well.
1885 * Fixed a long standing channel key setting bug in client library.
1886 Weird that it has never surfaced before.
1888 * Fixed bug in channel deletion. If the entire channel is removed
1889 then it must also delete the references of the channel entry
1890 from the client's channel list as the client's channel entry and
1891 the channel's client entry share same memory.
1893 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1895 * Implemented CONNECT and SHUTDOWN commands in the client.
1897 * Implemented CLOSE command to the client.
1899 * Added the function silc_idlist_find_server_by_name into the
1900 files silcd/idlist.[ch].
1902 Added the function silc_idlist_find_server_by_conn into the
1903 files silcd/idlist.[ch].
1905 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1907 * DIE command was renamed to SHUTDOWN. Updated the both code
1910 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1911 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1913 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1916 * Added function silc_server_create_connection function to create
1917 connection to remote router. My server implementation actually
1918 does not allow router to connect to normal server (it expects
1919 that normal server always initiates the connection to the router)
1920 so the CONNECT command is only good for connecting to another
1923 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1925 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1926 or some other client was kicked from the channel.
1928 Implemented the handling of the notify type to both client
1931 Implemented silc_server_send_notify_kicked to send the KICKED
1932 notify. It is used to send it to the server's primary router.
1934 * Implemented the KICK command into server and client.
1936 * Added `query' argument to the silc_idlist_get_client function
1937 to indicate whether to query the client from server or not if
1940 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1941 to indicate that the client is not channel founder.
1945 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1947 * Removed the rng context from SilcPacketContext structure and
1948 changed that the packet routine uses the Global RNG API.
1950 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1952 * Added support for quit message that client can "leave" on the
1953 channel when it quits the SILC. It is ditributed inside the
1954 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1956 Added silc_server_free_client_data that will take the
1957 signoff message as argument.
1959 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1961 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Updated parts of the protocol specification to keep it up
1966 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1968 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1969 payloads in one packet.
1971 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1972 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1973 use now the new List flag.
1975 * Also deprecated the following packet types: REPLACE_ID,
1976 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1978 * Added list support for Notify packet in server.
1980 * Added silc_server_send_notify_channel_change to send the
1981 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1982 the silc_server_send_replace_id.
1984 * Added silc_server_send_notify_nick_change to send the
1985 NICK_CHANGE notify type. Deprecates the function
1986 silc_server_send_replace_id.
1988 * Added silc_server_send_notify_join to send the JOIN notify type.
1989 Deprecates the function silc_server_send_new_channel_user.
1991 * Added silc_server_send_notify_leave to send LEAVE notify type.
1992 Deprecates the function silc_server_send_remove_channel_user.
1994 * Added silc_server_send_notify_cmode and
1995 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1996 types. Deprecates the silc_server_send_set_mode function.
1998 * Added SERVER_SIGNOFF notify type to indicate that server has
1999 quit. This means that all clients on the channel from that
2000 server will drop. This can be also used when netsplit happens.
2002 Deprecated REMOVE_ID packet type since it is not needed anymore
2005 Added silc_server_send_notify_server_signoff to send the
2006 SERVER_SIGNOFF notify type. Deprecates the function
2007 silc_server_send_remove_id.
2009 Added also silc_server_send_notify_signoff to send the
2010 SIGNOFF notify type.
2012 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2013 SILC protocol from this day on. Changed the protocol
2014 specification as well.
2016 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2017 notify type. It is used between routers to notify about
2018 topic changes on a channel.
2020 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2023 * Partly updated the protocol specification to comply with the
2024 changes now made. It is still though a bit outdated.
2026 * The JOIN notify type now takes one extra argument <Channel ID>.
2027 The packet used to be destined to the channel but now the
2028 JOIN type may be sent as list thus it is impossible to
2029 destine it to any specific channel. By adding this argument
2030 it is again possible.
2032 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2034 * Added CREDITS file. The CHANGES and CREDITS file will appear
2035 in the distribution as well.
2037 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2039 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2040 types in the server's silcd/packet_receive.c.
2042 * Implemented CMODE and CUMODE to work in router environment.
2044 * Fixed minor encoding and decoding buglet from the
2045 lib/silccore/silcmode.c.
2047 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2050 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2052 * Changed all SilcConfigServer* and silc_config_server* to
2053 SilcServerConfig* and silc_server_config*, respectively.
2056 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * Associated the ID (client or server ID) to the Authentication
2059 Payload to avoid any possibility of forging. Updated the
2060 protocol specification and the code accordingly.
2062 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * The RSA key length is now save to the RsaKey context in the
2065 key generation process in lib/silccrypt/rsa.c. The key length
2066 is now used to figure out the maximum size of the block allowed
2067 to be encrypted/signed.
2069 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2070 is equivalent to the silc_mp_mp2bin but does not allocate any
2073 * Changed silc_mp_mp2bin API to take length argument. If it is
2074 non-zero then the buffer is allocated that large. If zero, then
2075 the size is approximated using silc_mp_sizeinbase, which however
2078 * Created Global RNG API which is global RNG that application can
2079 initialize. After initializing, any routine anywhere in the
2080 code (including library) can use RNG without allocating a new
2081 RNG object. This was done to allow this sort of use of the
2082 RNG in code that has no chance to allocate RNG object. All
2083 applications currently allocate this and many routines in the
2084 library use this. Affected file lib/silccrypt/silcrng.[ch].
2086 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2087 it to use the Global RNG API.
2089 * Defined Authentication Payload into protocol specification that
2090 is used during SILC session to authenticate entities. It is
2091 used for example by client to authenticate itself to the server
2092 to obtain server operator privileges.
2094 Implemented this payload into the lib/silccore/silcauth.[ch].
2095 Implemented also routines for public key based authentication
2096 as the new protocol specification dictates.
2098 Moved definitions of different authentication methods from
2099 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2101 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2102 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2103 silc_pkcs_verify_with_hash functions into the file
2104 lib/silccrypt/silcpkcs.[ch].
2106 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * The client entry's userinfo pointer must be always valid.
2109 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2110 will fail since it requires the userinfo. Now, the userinfo
2111 is allocated as "" if actual userinfo does not exist. Actually,
2112 it must exist and it is totally Ok to drop client connections
2113 that does not announce the userinfo. However, we will make
2114 this workaround for now.
2116 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2117 to return the remote port by socket.
2119 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2121 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2122 SILC_SERVER_PENDING_EXEC and added an new macro
2123 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2124 data or when error occurs while processing the pending command.
2126 Added new argument `destructor' into silc_server_command_pending
2127 and to the SilcServerCommandPending object. This destructor is
2128 now called after calling the pending callback or if error occurs
2129 immediately. If error occurs the actual pending callback won't
2130 be called at all - only the destructor. The destructor may be
2131 NULL if destructor is not needed.
2133 All this applies for client library code as well. Similar
2134 changes were made there as well for the pending commands.
2136 In the client, the application must now allocate the
2137 SilcClientCommandContext with the silc_client_command_alloc
2140 * Added reference counter to the SilcServerCommandContext. Added
2141 function silc_server_command_alloc and silc_server_command_dup
2144 Same type of functions added to the client library for the same
2147 * Removed the cmd_ident from IDListData away since it is now
2148 global for all connections. It is the command identifier used
2149 in command sending and with pending commands. The affected file
2152 * Added reference counter to the SilcSocketConnection objecet to
2153 indicate the usage count of the object. The object won't be
2154 freed untill the reference counter hits zero. Currently only
2155 server uses this, and client ignores it. The client must be
2156 set to use this too later. The affected files are
2157 lib/silccore/silcsockconn.[ch]. Added also the function
2158 silc_socket_dup to increase the reference counter.
2160 This was mainly added because it is possible that the socket
2161 is removed underneath of pending command or other async
2162 operation. Now it won't be free'd and proper DISCONNECTING
2163 flags, etc. can be set to avoid sending data to connection that
2164 is not valid anymore.
2166 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2167 the connection. After that it sets SILC_SET_DISCONNECTED.
2168 It is, however, possible that the socket data is not still freed.
2169 The silc_server_packet_process now checks that data is not
2170 read or written to connection that is DISCONNECTED. The socket
2171 get's freed when the reference counter hits zero.
2173 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2175 * Changed the client operation API: channel_message operation's
2176 `sender' is now the client entry of the sender, not the nickname
2177 and the `channel' is the channel entry, not the channel name.
2179 In the private_message operation the `sender' is now also the
2180 client entry of the sender not the nickname.
2182 Affected file is lib/silcclient/ops.h and all applications
2183 using the client operations.
2185 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2187 * Moved the calling of ops->connect() from connect_to_server_final
2188 into receive_new_id functin since that is the point when the
2189 client is actually allowed to send traffic to network. The
2190 affected file is lib/silcclient/client.c.
2192 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2194 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2195 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2196 (if needs broadcasting) instead of broadcasting the packets one
2197 by one which would make a burst in the network traffic.
2199 * Added `broadcast' argument to the functions in silcd/server.[ch]
2200 silc_server_create_new_channel[_with_id] to indicate whether
2201 to send New Channel packet to primary router.
2203 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2205 * Added new function into the silcd/server.[ch] files:
2206 silc_server_create_new_channel_with_id to create new channel with
2207 already existing Channel ID.
2209 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2210 lib/silccore/silcpacket.h. This packet is used t send list of
2211 Set Mode payloads inside one packet. Server uses this to set
2212 the modes for the channels and clients on those channels, that it
2213 announced to the router when it connected to it. The protocol
2214 specification has been updated accordingly.
2216 * The silc_server_new_channel did not handle the packet coming
2217 from normal server as it normally does not send that. However,
2218 when it announces its channels it does send it. Implemented
2219 the support for that.
2221 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2222 into the file lib/silccore/id.h.
2224 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2226 * Fixed memory leaks in the functions silc_idlist_del_client,
2227 silc_idlist_del_channel and silc_idlist_del_server in the file
2228 silcd/idlist.c. All of those leaked like a sieve.
2230 * Fixed some small memory leaks in the client's function
2231 silc_client_notify_by_server.
2233 * Added functions into silcd/server.c: silc_server_announce_clients,
2234 silc_server_announce_channels and silc_server_announce_server.
2235 These functions are used by normal and router server to announce
2236 to its primary router about clients, channels and servers (when
2237 router) that we own. This is done after we've connected to the
2240 These functions effectively implements the following packet types:
2241 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2242 and SILC_PACKET_NEW_ID_LIST.
2244 * Added new functions into the silcd/packet_receive.[ch]:
2245 silc_server_new_id_list, silc_server_new_channel_list and
2246 silc_server_new_channel_user_list to handle the incoming
2247 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2249 * Added support of changing Channel ID in the function
2250 silc_server_replace_id. If the server that announces a channel
2251 to the router already exists in the router (with same name but
2252 with different Channel ID), router is responsible to send
2253 Replace ID packet to the server and force the server to change
2254 the Channel ID to the one router has.
2256 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2257 client that the Channel ID has been changed by the router. The
2258 normal server sends this to the client. Client must start using
2259 the new Channel ID as the channel's ID.
2261 Implemented handling of this new type into lib/silcclient/client.c
2262 into the function silc_client_notify_by_server.
2264 * Added new function silc_idlist_replace_channel_id into the files
2265 silcd/idlist.[ch] to replace the Channel ID.
2267 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2269 * Call silc_server_command_identify_check always when processing
2270 the IDENTIFY command in silcd/command.c
2272 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2274 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2275 send keepalive packets. The packet can be sent by clients,
2276 servers and routers.
2278 Added function silc_socket_set_heartbeat into the file
2279 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2280 If not set, the heartbeat is not performed. The actual
2281 heartbeat is implemented in the low level socket connection
2282 library. However, application is responsible of actually
2285 Added silc_server_send_heartbeat to send the actual heartbeat
2286 packet into silcd/packet_send.[ch]. Server now performs
2287 keepalive with all connections.
2289 * Added silc_task_get_first function into lib/silcutil/silctask.c
2290 to return the timeout task with shortest timeout. There was a bug
2291 in task unregistration that caused problems. TODO has been
2292 updated to include that task system must be rewritten.
2294 * The client library will now resolve the client information when
2295 receiving JOIN notify from server for client that we know but
2296 have incomplete information.
2298 * Rewrote parts of silc_server_remove_from_channels and
2299 silc_server_remove_from_one_channel as they did not remove the
2300 channel in some circumstances even though they should've.
2302 * Encryption problem encountered in server:
2304 The LEAVE command used to send the Channel Key packet to the
2305 router immediately after generating it. However, the code
2306 had earlier sent Remove Channel user packet but not immediately,
2307 ie. it was put to queue. The order of packets in the router
2308 was that Channel Key packet was first and Remove Channel User
2309 packet was second, even though they were encrypted in the
2310 reverse order. For this reason, MAC check failed. Now, this
2311 is fixed by not sending the Channel Key packet immediately but
2312 putting it to queue. However, this is more fundamental problem:
2313 packets that are in queue should actually not be encrypted
2314 because packets that are sent immediately gets encrypted
2315 actually with wrong IV (and thus MAC check fails). So, packets
2316 that are in queue should be encrypted when they are sent to
2317 the wire and not when they put to the queue.
2319 However, the problem is that the current system has not been
2320 designed to work that way. Instead, the packet is encrypted
2321 as soon as possible and left to the queue. The queue is then
2322 just purged into wire. There won't be any fixes for this
2323 any time soon. So, the current semantic for packet sending
2326 o If you send packet to remote host and do not force the send
2327 (the packet will be in queue) then all subsequent packets to the
2328 same remote host must also be put to the queue. Only after the
2329 queue has been purged is it safe again to force the packet
2332 o If you send all packets immediately then it safe to send
2333 any of subsequent packets through the queue, however, after
2334 the first packet is put to queue then any subsequent packets
2335 must also be put to the queue.
2337 Follow these rules and everything works fine.
2339 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Added new function silc_server_remove_clients_by_server to
2342 remove all client entries from ID list when the server connection
2343 is lost. In this case it is also important to invalidate all
2344 client entires as they hold the invalid server entry. This
2345 fixes fatal bug when server has lost connection and will reconnect
2348 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2350 * Made some sanity checks to silc_server_daemonise like to check
2351 whether the requested user and group actually exists.
2353 * Added sanity check to SKE's silc_ske_responder_finish to check
2354 that the public and private key actually is valid.
2356 * Invalidate the client's nickname when receiving Replace ID
2357 packet and the Client ID is being replaced. This means that the
2358 server will query the nickname if someone needs it (client)
2361 * Sort the ID Cache in client library when the ID Cache data
2362 has changed (needs sorting).
2364 * Do not allow for SILC client to create several connections to
2365 several servers. The client does not support windows right now
2366 and generating multiple connections causes weird behaviour.
2368 Irssi-silc client does support windows and can handle several
2369 connections without problems, see: www.irssi.org and SILC plugin.
2371 * Fixed some places where client was added to the IDList. The
2372 rule of thumb is following (in order to get everything right):
2373 If the client is directly connected local client then the
2374 `connection' argument must be set and `router' argument must be
2375 NULL to silc_idlist_add_client function. If the client is not
2376 directly connected client then the `router' argument must
2377 bet set and the `connection' argument must be NULL to the
2378 silc_idlist_add_client function.
2380 * The funtion silc_server_packet_send_local_channel actually did
2381 not check whether the client was locally connected or not. It
2382 does that now. Fixed a bug related to LEAVE command.
2384 * Fixed Remove Channel User payload parsing bug in server's
2385 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2387 * The server's silc_server_save_channel_key now checks also the
2388 global ID list for the channel as it might not be in the local
2389 list. Fixed a bug related to LEAVE command.
2391 * Is this the end of the [<unknown>] buglet that has been lurking
2392 around for a long time? A little for loop fix in server's
2393 silc_server_command_whois_parse that is used by both IDENTIFY
2394 and WHOIS command. At least, this was a clear bug and a cause
2395 of one type of [<unknown>] buglet.
2397 * WHOIS and IDENTIFY commands call the function
2398 silc_server_command_[whois/identify]_check function even if
2399 we are not router server.
2401 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2403 * Added --with-gmp configuration option. If set the GMP
2404 is always compiled in the SILC source tree. If not set then
2405 it is checked whether the system has the GMP3 installed. If
2406 it has then the GMP won't be compiled (the system's headers
2407 and library is used), if it doesn't have it then the GMP is
2408 compiled in the SILC source tree.
2410 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2412 * Changed RSA private exponent generation to what PKCS #1
2413 suggests. We try to find the smallest possible d by doing
2414 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2415 not security fix but optimization.
2417 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2419 * Added new config entry [Identity] to fork the server and run
2420 it as specific user and group. A patch from Bostik.
2422 * Imported Dotconf configuration library into lib/dotconf.
2423 This will be used to create the SILC configuration files later.
2424 It will appear in the distsribution after this commit.
2426 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2428 * A big code auditing weekend happening. Auditing code for
2429 obvious mistakes, bugs and errors. Also, removing any code
2432 Removed files for being obsolete:
2434 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2435 inline in the file lib/silcutil/silcbuffer.h)
2437 o lib/silcutil/silcbufutil.c (the header has inline versions)
2439 Changed code to fix possible error conditions:
2441 o The buffer formatting routines now check that the destination
2442 buffer really has enough space to add the data. This applies for
2443 both buffer formatting and unformatting
2444 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2445 unformatting was changed to accomodate following rules:
2446 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2447 sent to the function while XXX_*STRING will not allocate or copy
2448 the data into the buffer. Instead it sets the pointer from the
2449 buffer into the pointer sent as argument (XXX_*STRING used to
2450 require that the pointer must be allocated already). This change
2451 makes this whole thing a bit more consistent and more optimized
2452 (note that the data returned in the unformatting with XXX_*STRING
2453 must not be freed now). The routines return now -1 on error.
2455 o Tried to find all code that use buffer_format and buffer_unformat
2456 and added return value checking to prevent formatting and
2457 especially unformatting errors and possible subsequent fatal
2460 o Changed ske->x and ske->KEY to mallocated pointers in
2461 lib/silcske/silcske.h. Fixed possible data and memory leak.
2463 o Added return value checking to all *_parse* functions. Fixed
2464 many memory leaks as well.
2466 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2467 so that buffer overflows would not happen. All code now also
2468 checks the return value as it can fail.
2470 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2472 * Added reconnection support to server if the normal server looses
2473 its connection to the router (for example if router is rebooted).
2474 The server performs normal reconnection strategy implemented
2475 to the server. Affected file silcd/server.c.
2477 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2479 * Added new packet type SILC_PACKET_SET_MODE that is used to
2480 distribute the information about changed modes (for clients,
2481 channels and clients channel modes) to all routers in the
2482 network. Updated the protocol specification accordingly.
2484 Added functions into silcd/packet_send.c and
2485 silcd/packet_receive.c: silc_server_send_set_mode,
2486 silc_server_set_mode.
2488 Added new files silcmode.[ch] into lib/silccore that implements
2489 the encoding and decoding of Set Mode Payload. Added new type
2490 SilcSetModePayload. Moved the definitions of different modes
2491 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2493 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2495 * Oops, a little mistake in server's connection authentication
2496 protocol. The protocol is not ended with FAILURE but with
2497 SUCCESS if the authentication is Ok. :) Affected file is
2500 * Implemented NICK_CHANGE notify handling in server in the file
2501 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2502 the local clients on the channel. After the changing nickname
2503 in router environment snhould work and the [<unknown>] nickname
2504 should appear no more.
2506 The silc_server_replace_id function that receives the Replace ID
2507 payload now sends the NICK_CHANGE notify type also in the file
2508 silcd/packet_receive.c
2510 * Changed WHOIS and IDENTIFY command to support the maximum amount
2511 of arguments defined in protocol specs (3328 arguments). This
2512 fixed a bug that caused problems when there were more than three
2515 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2517 * Added extra parameter, command identifier, to the
2518 silc_client_send_command so that explicit command identifier
2521 Changed that ID list routines uses specific command identifier
2522 when sending WHOIS/IDENTIFY requests to the server so that they
2523 can be identified when the reply comes back.
2525 Affected files lib/silcclient/command.[ch],
2526 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2528 * Added `sender' argument to silc_server_packet_send_to_channel
2529 to indicaet the sender who originally sent the packet to us
2530 that we are now re-sending. Ignored if NULL. Affected file
2531 silcd/packet_send.[ch].
2533 * Added some server statistics support in silcd/server_internal.h
2534 SilcServerStatistics structure and around the server code. Also
2535 send some nice statistics information when client is connecting
2538 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2540 * Fixed channel ID decoding in server's JOIN command reply in
2541 silcd/command_reply.c
2543 * Fixed braodcasting of replace ID payload to not to send it if
2544 we are standalone server in silcd/packet_receive.c.
2546 * Fixed all channel message sending routines to not to send
2547 packets to clients that has router set, since they are routed
2548 separately in the same function earlier. Affects file
2549 silcd/packet_send.c and all channel packet sending functions.
2551 * In USERS reply, res_argv[i] are not allocated, the table
2552 is allocated. Thus changed that free the table, not its
2555 * In server's whois_check and identify_check if the client is
2556 locally connected do not send any WHOIS commands - they are not
2559 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2561 * Fixed some minor bugs in client when sending WHOIS command. The
2562 arguments was in wrong order.
2564 * Removed statis function add_to_channel from server in
2565 silcd/command.c that was previously used with the joining but
2568 * Tested USERS command in router environment successfully with two
2569 routers, two servers and two clients.
2571 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2573 * Reorganized the USERS command and command reply in client library
2574 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2575 When the command is given by user we register a pending command
2576 callback that will reprocess the command after the reply has been
2577 received from the server. When reprocessing the packet we then
2578 display the information. Thus, the USERS information is displayed
2579 now in the command callback instead of in the command reply
2580 callback. The processing of the command is same as previously
2581 when server has sent the command reply in the JOINing process.
2583 * Added to USERS command in silcd/command_reply.c to join the client,
2584 we didn't use to know about, to the channel after we've created
2585 a client entry for it. Also, for clienet we did know already still
2586 check whether it is on the channel or not and add it if not.
2588 * Removed silc_server_command_join_notify as the function and its
2591 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Changed the client's pending command handling to the same as the
2594 server's pending command handling. It is also now possible to
2595 execute command reply functions from other command reply
2596 function as the function callbacks for commands and command
2597 replies are one and same. The pending commands are not static
2598 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2599 in client connection context. Thus, pending commands are server
2600 connection specific as it is convenient.
2602 Changed the function silc_client_command_pending and
2603 silc_client_command_pending_del and added new function
2604 silc_client_command_pending_check. Removed the
2605 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2608 * Added cmd_ident, current command identifier, to the client
2609 connection context in lib/silcclient/client.h to keep track on
2610 command identifiers used in command sending. Client's command reply
2611 function handling now supports the mandatory command identifiers.
2613 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2614 funtions in client to fully support pending command callbacks.
2616 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2617 as one of the arguments to the application in the command reply
2620 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2621 before first releasing SILC but came back. Now it is removed again
2622 and should come back nomore. The FORWARDED flag was used only
2623 by the JOINing procedure by forwarding the command packet to router.
2624 Now, the JOINing procedure has been changed to more generic (due
2625 to various router environment issues) and FORWARDED is not needed
2626 anymore for anything. The protocol specification is yet to be
2629 Now, removed silc_server_packet_forward from server and the flag
2630 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2632 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * Renamed NAMES command to USERS command. The NAMES was named that
2635 due to historical reasons. Now it is renamed. Also, rewrote
2636 parts of the USERS command. The nickname list is not sent anymore
2637 by the server. Only Client ID and mode lists are sent in the USERS
2638 command. Changed this also to the protocol specification.
2640 The client now resolves the names and stuff after it receives
2641 the USERS list from the server when joining to the channel.
2643 * WHOIS and IDENTIFY commands has been changed to support multiple
2644 Client ID's per command. One can now search for multiple users
2645 in the network by sending only one WHOIS or IDENTIFY command.
2646 Changed the code and the protocol specifications.
2648 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2649 uses silc_server_command_whois_parse to parse the request. */
2651 * If normal server, do not parse the WHOIS and IDENTIFY requests
2652 before sending it to the router. Saves some time.
2654 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2656 * Fixed JOIN command on client library. Wrong number of arguments
2657 used to crash the client.
2659 * Added silc_server_channel_has_global function to check whether
2660 channel has global users or not.
2662 * Added silc_server_channel_has_local function to check whether channel
2663 has locally connected clients on the channel.
2665 * The silc_server_remove_from_one_channel now checks whether the
2666 channel has global users or not after given client was removed from
2667 the channel. It also checks whether the channel has local clients
2668 on the channel anymore. If it does not have then the channel entry
2669 is removed as it is not needed anymore.
2671 * The silc_server_notify now checks on JOIN notify whether the joining
2672 client is one of locally connected or global. If it is global then
2673 the channel has now global users on the channel and that is marked
2674 to the channel entry. Also, it now saves the global client to
2675 global list who is joining and JOINs it to the channel. This is
2676 for normal server, that is.
2678 Changed silc_server_send_notify_on_channel,
2679 silc_server_packet_relay_to_channel and
2680 silc_server_packet_send_to_channel check if we are normal server
2681 and client has router set (ie. global client) do not send the
2682 message to that client, as it is already routed to our router.
2684 * Implemented LEAVE notify type handling in silc_server_notify
2687 * Tested LEAVE command in router environment successfully. Tested
2688 with two routers, two servers and two clients.
2692 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2694 * Implemented SIGNOFF notify type handling in silc_server_notify
2697 * silc_server_remove_id now removes the client entry from all channels
2698 it has joined and thusly sends SIGNOFF notify type.
2700 * Rewrote the NAMES list generation in server by removing two excess
2701 loops. The lists are created now inside one loop.
2703 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2705 * silc_server_remove_channel_user checks now also global list
2706 for channel and client.
2708 * silc_server_new_channel_user checks now both local and global
2709 list for channel and client. Fixed a bug in client id decoding.
2710 Used to decode wrong buffer.
2712 * silc_server_channel_message checks now both local and global
2713 list for channel entry.
2715 * Tested channel joining (hence JOIN) in router environment
2716 successfully. Tested with two routers, two servers and two
2719 * Tested channel message sending in router environment successfully.
2721 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Added silc_server_save_channel_key into server.[ch] to save the
2724 received channel key in Channel Key payload processing. It is
2725 also used in JOIN command reply handling.
2727 Equivalent function silc_client_save_channel_key added into
2728 client.[ch] into client library.
2730 * Changed JOIN command reply to send information whether the channel
2731 was created or not (is existing already) and the channel key
2732 payload. Changed protocol specs accordingly.
2734 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2735 the request was sent by ID and not by nickname. Crashed on
2738 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2740 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2741 now correctly save the received data.
2743 * silc_server_free_sock_user_data now notifies routers in the
2744 network about entities leaving the network.
2746 At the same time implemented functions silc_server_remove_id
2747 and silc_server_send_remove_id to receive and send REMOVE_ID
2748 packets. The packet is used to notify routers in the network
2749 about leaving entities. The ID removed will become invalid in
2752 * Added function silc_idlist_del_server into server. Removes and
2753 free's server entry from ID list.
2755 * silc_server_private_message function now checks, if we are router,
2756 that the destination ID really is valid ID, naturally.
2758 * In router when NEW_ID packet is received (for new client) the
2759 hash of the Client ID is saved in the ID Cache but the
2760 client->nickname is set to NULL, instead of putting the hash
2763 IDENTIFY command now also checks that client->nickname must be
2764 valid. If it is not if will request the data from the server who
2765 owns the client. Added new function
2766 silc_server_command_identify_check.
2768 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2769 to set the command to already allocated Command Payload.
2771 * Tested private message sending in router environment with two
2772 routers, two servers and two clients. Fixed minor bugs and now
2775 * Fixed segfault from client's NAMES command. Used to crash if
2778 * Forwarded packets must not be routed even if it is not destined
2779 to the receiver. Changed server code comply with this.
2781 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2783 * Added `require_reverse_mapping' boolean value to ServerParams
2784 structure. If TRUE (not default) the server will require that
2785 the connecting host has fully qualified domain name.
2787 If the reverse mapping is not required and hostname could not be
2788 found the IP address is used as hostname.
2790 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2792 * Implemented version string checking to both client and server.
2793 The check is incomplete currently due to the abnormal version
2794 strings used in development version of SILC.
2796 * Changed all command functions in server to use the new
2799 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Changed char *data to unsigned char *data in ID Cache system to
2802 support binary data as ID Cache data. Changed code to support
2803 binary data in lib/silccore/idcache.c.
2805 * Renamed silc_server_packet_relay_command_reply to
2806 silc_server_command_reply as it is normal packet receiving
2807 function. Rewrote the function to accept command replys for
2808 servers and not only for clients.
2810 * Mark remote router always as registered server if we are connecting
2811 to it. Otherwise, commands sent by the router to us are ignored.
2813 * All ID List find routines now returns the ID Cache Entry pointer
2814 as well if requested.
2816 * WHOIS command works now in router environment, tested with two
2817 routers, two servers and two clients.
2819 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2820 in router environment (as it is almost equivalent to WHOIS) but
2821 hasn't been tested thoroughly. Added new functions:
2823 silc_server_command_identify_parse
2824 silc_server_command_identify_send_reply
2825 silc_server_command_identify_from_client
2826 silc_server_command_identify_from_server
2828 * Disabled route cache adding because adding two different ID's with
2829 same IP replaces the old cache entry thus giving wrong route.
2830 The entry->router->connection is always the fastest route anyway
2831 so route cache may not be needed. Of course, new routes maybe
2832 established after receiving the ID when the entry->router->connection
2833 might not be anymore the most optimal.
2835 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2837 * Add route cache for received ID for fast routing.
2839 * Added silc_server_packet_route to route received packet on router
2840 that is not destined to us.
2842 * Renamed silc_server_get_route to silc_server_route_get.
2844 * Added id_string and id_string_len fields into SilcServer to
2845 include encoded ServerID for fast comparing without excess
2846 encoding of the ID's.
2848 * Cleaned up WHOIS command on server side. Added following static
2851 silc_server_command_whois_parse
2852 silc_server_command_whois_check
2853 silc_server_command_whois_send_reply
2854 silc_server_command_whois_from_client
2855 silc_server_command_whois_from_server
2857 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2858 arguments in command replies. All command functions should be
2859 updated to use this macro.
2861 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2863 * Minor typo fixes on command reply handling on server.
2865 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Added silc_server_command_add_to_channel internal routine to add
2868 the client to the channel after router has created the channel and
2869 sent command reply to the server.
2871 * Added generic silc_server_send_command to send any command from
2874 * Use static buffer with ID rendering instead of duplicating data.
2876 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Fixed a channel user mode bug when joining to a channel server gave
2879 everybody channel founder rights, oops.
2881 * We mark ourselves as the router of the incoming server connection
2882 if we are router ourselves. This way we can check in some packet
2883 sending functions whether it is locally connected server. For
2884 incoming router connections we put NULL.
2886 * For router sending packets locally means now always sending the
2887 packet cell wide; to local clients and local servers. For normal
2888 server sending packet locally means sending it to only local
2891 * Fixed the JOIN command to really work in router environment. If the
2892 channel is created it is always created by the router. Router is
2893 also responsible of making the initial joining to the channel,
2894 sending JOIN notify to the sending server and distributing
2895 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2896 does not exist server doesn't do anything else but forward the
2897 command to the router which performs everything.
2899 * Added silc_server_send_channel_key function to send the Channel Key
2902 * Added silc_server_create_channel_key to create new channel key. The
2903 channel key is now re-generated everytime someone joins or leaves
2904 a channel, as protocol dictates. Note: channel->key_len is the
2907 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2910 packet_receive.[ch] to separate packet sending and receiving
2911 routines. The server.[ch] now includes everything else including
2912 actual packet processing (writing and reading data) and other
2915 Renamed silc_server_private_message_send_internal to
2916 silc_server_send_private_message. The routine is still though
2917 used only to relay private messages as server does not send
2918 private messages itself.
2920 Renamed silc_server_new_channel to silc_server_create_new_channel
2921 and added new function sicl_server_new_channel that handles the
2922 incoming New Channel packet. Added also new sending function
2923 silc_server_send_new_channel to send New Channel Payload.
2925 * Added new function silc_server_notify to process incoming notify
2926 packet to the server/router. Server may then relay the notify
2927 to clients if needed.
2929 * Added new function silc_server_new_channel_user to process incoming
2930 New Channel User packet. Router will redistribute the packet and
2931 send JOIN notify to its local clients and locally connected servers
2932 if needed. Normal server will send JOIN notify to its local client
2933 on same channel when received this packet. Added also corresponding
2934 sending function silc_server_send_new_channel_user to sent the
2937 * Added boolean route argument to send_notif_to_channel and
2938 packet_send_to_channel functions to attempt to route the packet
2939 if it is TRUE and send only locally if it is FALSE.
2941 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2943 * silc_server_replace_id now broadcasts the received replace ID
2944 packet if it is not broadcast packet already. The router must
2945 broadcast to inform other routers about changed ID.
2947 * Added backpointer to server's router into SilcServer context in
2948 silcd/server_internal.h.
2950 * Fixed silc_server_packet_broadcast to send correct broadcast
2953 * The channel key is now distributed to the local client as soon
2954 as it is received from the router (in router environment) so that
2955 no other packet may be sent for the channel until client has
2958 * silc_server_remove_channel_user now broadcasts the received
2959 Remove Channel User packet if it is not broadcast packet already.
2960 The router must broadcast to inform other routers about removed
2963 * Added users field into SilcPacketContext that is a reference count
2964 of the context. One can increase the reference count by calling
2965 silc_packet_context_dup which is now changed to just increase the
2966 reference count instead of duplicating the data. The reference
2967 count is decresed by calling silc_packet_context_free that will
2968 free the data after the reference count hits zero.
2970 For now on the packet context and everything allocated into it
2971 (including the raw packet from network) must be freed by calling
2972 the new silc_packet_context_free function. Added also new function
2973 silc_packet_context_alloc that must be used now to allocate the
2974 context. This also means that if a routine is asynchronous from
2975 silc_[client/server]_packet_parse_type the packet context must
2976 be duplicated by calling silc_packet_context_dup. Otherwise it
2977 gets free'd after silc_[client/server]_packet_parse_type returns.
2978 Also, one must remember that if packet is duplicated then its
2979 reference count must be decresed by calling the free function as
2980 many times as it was duplicated.
2982 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2983 from both client and server.
2985 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2987 * Made joining to a channel working in router environment.
2989 * Cleaned up JOIN command on server side and create function
2990 silc_server_command_join_channel internal routine to make the
2993 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Changed silc_command_pending list to SilcDList. Also, added
2996 `ident' field to SilcServerCommandPending structure to identify
2997 the reply and to call correct callback.
2999 Added silc_server_command_pending_check function to replace the
3000 corresnponding macro. The silc_command_pending list is not
3003 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3004 to set identifier to previously allocated Command Payload. It
3005 is used to set identifier for command when resending Command
3008 * Added silc_command_payload_encode_payload to encode Command
3009 Payload buffer from SilcCommandPayload structure.
3011 * Added silc_argument_payload_encode_payload to encode Argument
3012 payload buffer from SilcArgumentPayload structure.
3014 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3016 * Changed WHOIS command to support router connection on server side.
3017 The whois request is always sent to router unless the server is
3018 standalone server. After server has received the reply from the
3019 router will it send the reply to the client.
3021 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3022 broadcast received broadcast packet. The function is used only
3023 by router. The broadcast packet is always sent to the router's
3026 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3027 render given ID to printable string, for log files for example.
3029 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Made basic router to router connections working. At least they
3032 can now connect to each other but nothing really works the way
3033 they are supposed - yet.
3035 * Added new initiator token to RouterConnection configuration
3036 file in silcd/serverconfig.[ch]. It is used to tell whether we
3037 are the initiator to the remote router or whether we'll expect
3038 the other end to connect.
3040 * Moved registering of listener task to silc_server_init, hence
3041 the server starts listenning as soon as it is run, even if it
3042 does not have connections to other routers. Let's see how well
3045 * Changed default connection retry timeouts for more suitable in
3048 * Removed cipher and such arguments from silc_idlist_add_client
3049 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3050 Added new function silc_idlist_add_data to add the keys and stuff
3053 * Added SilcIDListData structure and added it to SilcClientEntry
3054 and SilcServerEntry as their first field in the structure. This
3055 way we can explicitly cast the ID entries to the SilcIDListData
3056 structure and get common data for the entries. In past, we had
3057 to first check what type of connection it is and then cast it to
3058 correct ID entry type. Now, we can directly cast the opaque
3059 pointer to the SilcIDListData (no matter what ID entry it actually
3060 is) and get the data needed.
3062 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3064 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3065 in some circumstances even if threre were timeout tasks, though not
3066 IO tasks, but tasks anyway. Now fixed.
3068 * Defined SilcServerConnection structure to hold connection specific
3069 stuff about directly connected servers and routers. The definition
3070 is currently in silcd/server_internal.h. I thought about having
3071 a bit more important role fro this struct but for now it is used
3072 only when connecting to other server (or router actually).
3074 * Added connecting retry support in server when connecting to
3075 router(s). The retry feature implement exponential backoff
3076 algorithm. Also, added SilcServerParams structure to hold default
3077 parameters for server. For now, it include these retry settings
3078 and are hard coded. After server is moded to be as Silc Server
3079 Library this structure will be more important.
3081 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Changed client librarys channel->clients table to SilcList and
3084 changed code accordingly.
3086 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3088 * Changed client's channel table to SilcList and changed code
3089 accordingly. Also changed SilcChannelClientEntry to include back-
3090 pointer to the channel so that client entry can use that structure
3091 as list as well and we have fast cross-reference to the channel.
3092 This change dramatically decreased the complexity of channel
3093 handling with client entry and vice versa (removed one extra
3094 loop when searching for channel entry from many functions).
3096 * Changed server->sim from table to SilcDList and changed code
3099 * NAMES command can now be used from user interface. It will show
3100 the user list on the channel, neatly.
3102 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3103 Code now saves realname of the user if it becomes available.
3105 * Renamed configure.in to configure.in.pre and made ./prepare
3106 script to automatically add correct version string to
3107 configure.in which it creates from configure.in.pre.
3109 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * NAMES command reply now shows users mode with the nickname when
3114 * Moved silc_client_ch[u]mode[_char] functions from
3115 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3116 place sucks, they are utility functions and should be in some
3119 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3121 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3124 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * Added TRQ (efficient deque and list library) into lib/trq. This is
3129 a very good list library that is currently used in the SILC. Defined
3130 SilcList API over the library because I didn't like the API very
3131 much. See lib/trq/silclist.h for the API and examples of how to
3132 use the API. Fixed various places in the code to use the new
3133 SilcList API. The SilcList is meant for lists that has a structure
3134 already defined as a list. It is not suitable to add just some
3135 context to the list (in TRQ, the context is the list actually).
3137 So, I defined SilcDList that can be used for the purpose where
3138 predefined list structure does not exit. This can be used as
3139 such list. Now some context just can be added to the SilcDList.
3140 Currently this list is not used in the SILC just yet, though there
3141 are a lot places where this can replace dynamically allocated
3142 tables and I will fix these places, later, to use SilcDList.
3143 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3144 and use TRQ internally).
3146 Also fixed some annoying warning messages that the original TRQ
3147 code generated. Also minor changes to TRQ's Makefile.in.
3149 * Added support for querying by Client ID to both WHOIS and
3150 IDENTIFY commands into server, as required by the protocol.
3152 * Removed method function pointers from SilcBuffer structure. They
3153 weren't used to anything and just increased the context size for
3154 no good reason. This change also made silc_buffer_alloc and
3155 silc_buffer_free functions inline functions.
3157 * Disabled command flooding detection support until it's fixed so
3158 that it accepts commands in but does not execute them more than once
3161 * Added silc_net_localhost(), to return local hostname, into
3162 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3163 that must be initialized before calling silc_client_init.
3165 * Added new function: silc_server_send_notify_on_channels to send
3166 notify messages to all channels client has joined. It is assured
3167 that the message is sent only once per client.
3169 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3170 lib/silcutil/silcutil.[ch] as silc_format function. The new
3171 function is generic and is used by server as well, not only by
3172 the logging routines.
3174 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3175 the provided version string was not acceptable. Added new function:
3176 silc_ske_check_version into lib/silcske/silcske.h. The function
3177 must be implemented by the application (client or server) and it
3178 does not reside in the SKE library. The function checks the version
3179 string remote end sent.
3181 * Added back pointers (to opaque context and to SilcSocketConnection)
3182 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3184 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3185 duplicate packet context structure.
3187 * Changed `notify' client operation to send same arguments as client
3188 receives from server except for ID's. ID's are mapped to correct
3189 ID entry and that is returned. Also, if channel entry is not sent
3190 by server but the notify is for channel the channel entry is sent
3191 to application (otherwise application doesn't know that it is for
3192 channel (library gets it from packet's Destination ID)).
3194 * Added silc_client_remove_from_channels into client library to
3195 remove a client from all channels it has joined to. Used when
3196 received SIGNOFF notify from server. Added also new function
3197 silc_client_replace_from_channels to replace old ID entry with
3198 new ID entry on all channels. Used when received NICK_CHANGE
3201 * Fixed ID Cache list handling in silc_idlist_get_client in
3202 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3203 to get (or query) client by ID.
3205 * Updated TODO list.
3207 * Added connection authentication status message defined by the
3208 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3209 support for these into the code in client and server side.
3211 * Added generic function silc_client_send_command to send any command
3212 with variable argument list. Application should use this function
3213 to send commands if the command functions provided by the library
3214 does not suite for the application's user interface needs.
3216 * Added new `failure' client operation. Application is notified about
3217 received failure packet if client is executing a protocol. In this
3218 case the protocol's execution has failed.
3220 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3221 is required by the protocol.
3223 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3224 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3227 * Added status flag to SilcSKE object to indicate realtime status
3228 of the SKE protocol.
3230 * Application receives now exactly same command reply arguments as
3231 the library receives from server. However, if ID is received the
3232 corresponding ID entry is returned to the application (eg. Client
3233 ID is mapped to correct SilcClientEntry entry and that is returned).
3234 Changed command_reply client operation due to this change.
3236 * Changed all ID's in commands and in command replys as ID Payloads.
3237 Change affected both client and server side codes.
3239 All ID's sent in SILC network (with execption of ID's in SILC
3240 Packet header) are sent in ID Payload to support variable length
3243 * Server now notifies nick changes and notifies all clients on
3244 the channels about the new nickname (about the new Client ID,
3247 * Implemented CMODE command to change channel modes. Supports all
3248 channel modes defined by the protocol specs except ban and invite
3249 lists. (Also, private channel key mode is supported but support for
3250 setting private channel key in client is missing, thus, this mode
3251 has no effect on client side (except that server requires that the
3252 client uses private channel key and normal channel traffic does not
3255 Also, invite mode works per se, but INVITE command does not work
3256 yet correctly, so you can set channel as invite only channel but
3257 inviting clients to the channel does not work (it is yet to be
3258 thought what's the best way to do it).
3260 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3261 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3262 Implemented CUMODE command to change user's mode on the channel.
3263 Supports all modes defined by the protocol specs.
3265 * Added NAMES command reply to return users modes on the channel.
3267 * Removed unnecessary and slow ciphers from lib/silccrypt.
3269 * Set SO_KEEPALIVE option to connection sockets by default.
3271 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3273 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3274 redefined the Notify Payload into protocol specs.
3276 * Added silc_id_payload_parse_id to get ID directly from raw
3279 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3282 accept searching by Client ID as well.
3284 * Added support for LEAVE and SIGNOFF notify types in client library.
3286 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3287 to parse ID Payload from raw data.
3289 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Added flags parameter into silc_ske_assemble_security_properties
3292 function in lib/silcske/silcske.[ch].
3294 * Changed notify client operation to fit better for notify messages
3295 sent by server. The notify payload received from server is now
3296 passed to the application (after parsing it to SilcNotifyPayload).
3297 It is application's responsibility to retrieve the arguments
3298 from the payload and show the message the way it wants. The message
3299 sent by server is implementation specific.
3301 * Changed public keys to comply with the protocol specification.
3302 Old public keys are not supported anymore and are not compatible.
3304 * Removed nickname from Channel Payload as the latest draft removed
3305 it. The client must resolve the nickname from the NAMES command
3306 reply received when it joined the channel.
3308 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3310 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Fixed some errors in protocol specification drafts.
3314 * Created lib/silccore/silcnotify.c to implement Notify Payload
3315 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3316 generic payloads described by protocol specifications. The file
3317 includes implementations for ID Payload and Argument Payload.
3319 * Changed Command Payload implementation to use the new Argument
3320 Payload. Changed command_xxxx_payload to command_payload_xxxx
3321 to comply with SILC coding conventions.
3323 * Added suppport for Argument Payload handling in Notify Payload
3324 implementation as protocol requires it. Added the new support
3325 into server and client lib as well.
3327 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Added support for multiple nicknames on same channel. [n] is
3330 added locally to the nickname if there are more than one same
3331 nicknames on the channel.
3333 * Server now sends all nicknames that matched WHOIS request.
3334 Client also shows the list received from server.
3336 * Added TOPIC command to client side. User can now set and show
3337 current topic on channel.
3339 * Added MOTD command to client and server. Also, server sends the
3340 motd when client connects to the server.
3342 * Changed version strings to comply ISO 8601.
3344 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3346 * Fixed protocol error handling in client library. It should now
3347 cope even if the SKE fails for some reason.
3349 * Made new protocol specification drafts for submitting to IETF.
3351 * Implemented TOPIC command to server in silcd/command.c.
3353 * Added two new notify types into lib/silccore/silcnotify.h:
3354 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3355 notify nickname change and topic setting/change on a channel.
3357 * API change of command_reply operation in client library. The
3358 application gets now the status type received from server as well.
3360 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3364 * Cras fixed and optimized the packet handling even further and
3365 it should work now. Minor change to the prototype of function
3366 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3368 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3370 * Added new function into lib/silcutil/silcschedule.[ch]:
3371 silc_schedule_with_fd to select() a specified fd. The function
3372 returns after timeout expires or data arrives or goes. The
3373 function is used by packet routines to wait that all data is
3374 received from network.
3376 * Fixed data reading from network in lib/silccore/silcpacket.c.
3377 The code now assures that all data is read from the fd and then
3378 continues packet processing. This was a bug fix since the code
3379 used to drop some data in some circumstances.
3381 * Added new function into lib/silcclient/client.[ch]:
3382 silc_client_start_key_exchange to start key exchange after
3383 connection has been established to server. The code internally
3384 now uses this funtion but its main purpose was to provide it
3385 for applications that perform their own connecting. After
3386 application has created a connection it merely calls this
3387 function to start the key exchange between client and server.
3388 The library takes care of everything else after that.
3390 Updated also lib/silcclient/README to explain the usage of
3393 * Do not send to application information that connection has
3394 been established. Application gets notified it by connect
3397 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Applied cras's patch to add silc_schedule_one function. The
3400 function runs scheduler once and returns.
3402 * Fixed the scheduler after cras messed it up. The timeout
3403 handling works now as it's supposed to work.
3405 * Added into lib/silccore/ silcnotify.h to include notify
3406 message types support. Changed silc_server_send_notify*
3407 functions, in server.[ch], to support those new notify types.
3408 Added the support for the notify types into client library,
3409 as well. Added new notify client operation into ops.h in
3412 * Changed silc_server_packet_send_to_channel to send normal
3413 packets instead of just channel message packets. The function
3414 is now used to send the notify packets to channels. It is not
3415 used to send channel message packets anymore, as server never
3418 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3419 va_arg()s as it seems to require it nowadays. I guess, if SILC
3420 is compiled with older va_arg() the new code should work anyway.
3422 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Splitted core library. Core library (lib/silccore) includes
3425 now only SILC protocol specific core (and common) components.
3426 Created new utility library (lib/silcutil) that includes more
3427 generic purpose stuff. The stuff for util library was taken
3428 from the old core library. This was minor and easy split.
3430 * Created SILC Client Library (lib/silcclient) that includes
3431 implementation of the SILC client without user interface. This
3432 was major move from silc/ directory. The code has been changed
3433 so that it is transparent towards the user interface. The
3434 silc/ directory includes now the same user interface as before
3435 and it uses the new client library. Read lib/silcclient/README.
3436 Basicly, the client library performs everything else related
3437 to SILC except user interface handling. Also, configuration
3438 files are considered to be part of user interface and library
3439 does not handle them.
3441 This change also changed a lot of structures, function naming etc.
3442 Most important change was that SilcClientWindow object was
3443 renamed to SilcClientConnection in the client library. Created
3444 also new file lib/silcclient/ops.h. Also added new files
3445 silc/local_command.[ch] and silc/client_ops.[ch].
3447 All these changes were made to make it easier for user interface
3448 designers to create what ever user interface for the SILC client
3451 It is also expected that the server will be moved to lib
3452 directory as well and SILC Server Library will be created;
3453 sometimes in the future.
3455 * Removed Local commands from lib/silccore/silccommand.h as
3456 they are application specific and new client library does not
3457 handle any of those anymore.
3459 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3460 old client implementation in silc/.
3462 * Added support for callback functions in SILC_LOG_* macros.
3463 Application can now set its own callbacks that will be called
3464 instead of using the default functions that will always print
3465 the debug messages to stderr (or stdout). Also, debugging can
3466 now be disabled by setting silc_debug to FALSE and re-enabled by
3467 setting it to TRUE. Note, that logging will still work even
3468 if debugging is disabled.
3470 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3471 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3472 silc_log_reset_debug_callbacks.
3474 * To enable debugging in silc client one must give now -d
3475 option on command line.
3477 * Changed silc_schedule_init to automatically allocate task queues
3478 if they are not allocated before calling it.
3480 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Added GMP 3.1 into math library.
3484 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3487 a channel in SILC network. The packet is used by servers and
3488 routers to notify other routers that user has left a channel.
3489 This little feature was missing until now. Added the feature
3490 to protocol specification as well.
3492 Added functions: silc_server_send_remove_channel_user and
3493 silc_server_remove_channel_user into server.[ch].
3495 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3496 lib/silccore/silcpacket.h. However, they are not implemented
3499 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Fixed joining to a channel and sending channel messages
3502 between server and router. The channel message sending should
3503 now work inside a cell.
3505 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3507 * Fixed the private message sending between server and router.
3508 The private message sending should now work inside a cell.
3510 * Added silc_server_replace_id into server.[ch] to replace
3511 existing ID in the SILC network.
3513 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3514 and silc_idlist_replace_server_id into idlist.[ch] in server.
3516 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * Fixed the server to server connections. Server can again now
3519 connect to router. Router to router connections probably does
3522 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Added dynamic protocol registering support. Now protocols can
3525 registered and unregistered on the fly. Patch by cras.
3527 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3529 * Added lib/contrib directory to hold routines that some platforms
3530 don't have but are needed by SILC.
3532 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3533 into lin/contrib to provide getopt() and getopt_long() for
3534 those who don't have it.
3536 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3538 * Added AWAY command to client. When away message is set and
3539 client receives a private message packet the client automatically
3540 replies to the sender with the away message.
3542 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3543 bug seemed to be the cause of recent problems when compiling
3546 * Added version detection support to SKE protocol specification
3547 and added the new changes to the SKE implementation as well.
3548 There were other minor changes in the SKE protocol as well.
3550 Many changes in lib/silcske/silcske.[ch] and in
3551 lib/silcske/payload.[ch].
3553 * Added ^U functionality, clear input line. Patch from cras.
3555 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Mainly small bugfixes on core library. Fixed some debugging
3558 logging and buffer overflow in silclog.c.
3560 * Updated config.sub and config.guess on the distribution tree.
3562 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Added command lagging support in server. Client may execute
3565 commands now only once in two seconds.
3567 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Optimized packet reception. MAC computation and checking is now
3570 also more optimized. A lot previously duplicated code is now
3571 used as generic by both client and server.
3573 * Fixed key pair generation in clientutil.c
3575 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Added into lib/silccore/silcbufutil.[ch] new function;
3578 silc_buffer_realloc.
3580 * Moved generic packet sending/encryption functions to
3581 lib/silccore/silcpacket.[ch] from client and server. Some
3582 rewriting of the functions.
3584 * Moved all generic packet reception/decryption functions to
3585 lib/silccore/silcpacket.[ch] from client and server. The
3586 packet processing is now much cleaner in both client and server.
3587 These were major changes in both client and server.
3589 * Created many common functions in server to do packet sending.
3590 Previously code were duplicated a lot, this has been removed
3593 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3595 * Rewrote major parts of the ID cache system. Don't know
3596 whether it is better now or not but at least the API is more
3599 * Major rewrite on ID cache stuff on client because of the ID
3600 cache API changes. Added idlist.c to client.
3602 * Also major rewrite on ID cache stuff on server as well.
3603 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3604 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3605 in hand, instead they are all put into the ID cache system now.
3606 All server_idlist_* routines uses ID cache now instead of
3607 traversing its own lists (those lists does not exist anymore).
3608 SilcIDList though still exists. Also, SilcXXXEntry's are
3611 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Finally made the SKE implementation compliant to the protocol
3614 specification. All mp integers are now binary encoded as
3615 opposed being HEX encoded.
3617 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3620 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3621 functions: silc_[encode/decode]_pem. Also added function
3622 silc_encode_pem_file to PEM encode with newlines ('\n') for
3625 * SILC public keys are now encoded either PEM or binary. Same
3626 option is for private keys as well. By default private keys
3627 are binary encoded and public keys PEM encoded. Silly HEX
3628 encoding were removed.
3630 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3631 function to create fingerprints.
3633 * Fixed a bug in SHA1; does not change the original data anymore.
3635 * Partly implemented INFO command on client and server side.
3636 Fixed CLEAR command. Changes to SERVER command; show current
3637 server(s) when giving command without arguments. Added
3638 VERSION command to client.
3640 * Added check to server that unregistered connections cannot
3641 execute commands (unless it is specificly allowed).
3643 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Fixed screen refresh.
3647 * Fixed channel joining bug from client. On some circumstances
3648 client tried to join to a channel it had already joined.
3650 * Added public key verification process into client's protocol.c.
3651 The client now verifies the public key from user and saves
3652 it into ~./silc/serverkeys/ directory.
3654 Added into: clientutil.[ch]: silc_client_verify_server_key.
3656 * Changed SKE protocol's silc_ske_initiator_finish function
3657 to accept callback function that verifies the received public
3658 key. Removed old silc_ske_verify_public_key function.
3660 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3663 silc_pkcs_private_key[_data]_set.
3665 * Made the password and public authentication more cleaner in
3666 server's protocol.c.
3668 * Removed historic and obsolete protocol `channel_auth' from
3669 both client and server.
3671 * Removed wrong way of sending command status messages from
3672 server to client in server's command.c. The old way violated
3673 protocol specification.
3675 Changes to silccore/silccommand.[ch]: removed
3676 silc_command_encode_status_payload -> not needed anymore,
3677 changed silc_command_encode_payload_va to accept extra
3678 argument on variable argument list. The argument type must
3679 now be provided to the function. Also, added new function:
3680 silc_command_encode_reply_payload_va which is same as
3681 normal command_encode_payload_va except command status type
3682 is provided as extra argument.
3684 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Added ~./silc directory handling. The directory includes the
3687 public and private keys for the client.
3689 Added silc_client_check_silc_dir, silc_client_create_identifier
3690 and silc_client_load_keys.
3692 * Implemented SILC protocol compliant public key. Added public
3693 and private key saving to and loading from files.
3695 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3696 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3697 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3698 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3699 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3701 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3702 silc_pkcs_load_[public/private]_key.
3704 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3706 * Added silc_server_get_route (route.[ch]) to get connection
3707 data for the fastest route for given ID.
3709 * Implemented INVITE command on client and server. The command
3710 were re-defined in the SILC Protocol Specification and the
3711 implementation now complies with the specification.
3713 * Implemented PING command on client and server.
3715 * Implemented NAMES command on client and server. The server side
3716 supports currently only normal server not router server yet.
3717 Some changes to NAMES definition in SILC protocol specification.
3719 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3721 * Implemented LEAVE command on client and server.
3723 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3724 again. This change was made to the protocol as well. Server
3725 should not violate the protocol specification anymore.
3727 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3729 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3730 was tested. SOCKS4 was not but should work anyway.
