3 * Fixed channel joining notify handling, cumode notify handling
4 from Irssi SILC client.
6 * Added SILC specific module-formats to the Irssi SILC client so
7 that SILC specific message hilighting, colors etc is possible.
8 Affected file irssi/src/fe-common/silc/module-formats.[ch].
10 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
12 * Changed the ask_passphrase client operation to be ascynchronous.
13 It has now a completion callback and a context that the
14 application must call after it has got the passphrase from
15 the user. Affected files lib/silcclient/silcapi.h,
16 lib/silcclient/protocol.c, lib/silcclient/command.c and
19 Added SilcAskPassphrase callback that the application calls
20 to deliver the passphrase to the library.
22 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
23 The public key verification and especially a certificate
24 verification is asynchronous procedure.
26 Added new SILC_SKE_STATUS_PENDING status to indicate the
27 request is pending and a callback will be called to finalize
30 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
31 indicate that remote end did not send its public key (or
32 certificate), even though we require it. Added check for this
33 condition in the SKE. This was a security bug, now fixed.
35 Defined new SilcSKEVerifyCbCompletion callback that is called
36 when the verification process is completed.
38 The affected files lib/silcske/silcske_status.h and
39 lib/silcske/silcske.[ch].
41 * Changed the verify_public_key client operation to be async
42 as well. Defined SilcVerifyPublicKey callback that is used to
43 indicate the success of the public key verification process.
45 Changed the server and client to use the new async client
48 * Changed the Irssi SILC client's internal scheduler to be called
49 twice as many times as it used to be. As a result the client
50 should be a bit faster now. Affected file is
51 irssi/src/silc/core/silc-core.c.
53 * Added support to Irssi SILC client of asynchronous public key
54 verification and passphrase inquiry. Affected file is
55 irssi/src/silc/core/silc-core.c.
57 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
59 * Do not say "You have left channel %s" in client library.
60 Moved it to the application. Affected files are
61 lib/silcclient/command.c and silc/client_ops.c.
63 * Fixed silc_client_get_clients. Command context was not
64 duplicated and was freed memory in the callback. Affected
65 file lib/silcclient/idlist.c.
67 * Do not say "you are now talking..." on JOIN command in the
68 client library. The appliation must handle it.
70 * Do not say ".. changed topic to" in command reply in the
71 client libary. The application must handle it.
73 * Fixed TOPIC command sending in the client library.
75 * Fixed a memory leak in silc_client_command_free in the file
76 lib/silcclient/command.c.
78 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
80 * Imported a modified version of Irssi client to the source tree.
81 The Irssi will be used to create a new client called
82 Irssi SILC. Imported to irssi/.
84 Added silc_core_init_finish function to the Irssi. Affected
85 file irssi/configure.in.
87 A lot changes in the Makefile.ams around the irssi tree.
89 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
91 * Do not rehash if the new size is same as the old size of the
92 hash table, in the silc_hash_table_rehash*. The affected file
93 lib/silcutil/silchashtable.c.
95 * Replaced hash_table_del_by_context calls from the server
96 (when channel->user_list and client->channels) to the
97 hash_table_del as it is sufficient and faster.
99 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
101 * Added silc_hash_table_list, silc_hash_table_get and the
102 SilcHashTableList structure to provide an alternative way to
103 traverse the hash table. The affected files are
104 lib/silcutil/silchashtable.[ch].
106 * Changed the server's idlist routines to use the hash table
107 routines to optimize the code.
109 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Replaced the client entry's `channel' list and channel entry's
112 `user_list' list to hash tables for optimized lookup. Changed
113 the code to use the hash table interface around the code.
114 Affected file lib/silcd/idlist.[ch].
116 * Added `auto_rehash' boolean argument to the function
117 silc_hash_table_alloc to indicate whether the hash table should
118 auto-rehash when it thinks is appropriate time. It will
119 increase the hash table size if the there is twice as much
120 entries in the table than the size of the table, and will
121 decrease the size if there are twice as less entries than
122 the size of the table.
124 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
126 * Fixed silc_xxx_get_supported to not crash at some circumstances.
128 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
130 * silc_idcache_purge_by_context deletes the entry now by context
131 as it is supposed to do. Affected file lib/silccore/idcache.c.
133 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
134 client is not anymore valid (WHOWAS givens the info) and not
135 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
137 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
139 * Removed the `data' and `data_len' arguments from the ID Cache
140 interfaces and added `name' argument. ID Cache does not handle
141 anymore the binary data only a names associated with given ID.
143 * When hashing a Client ID with silc_hash_id the entire ID is
144 not hashed anymore, instead only the hash of the Client ID is
145 hashed. This way we can access the Client ID from the cache
146 with Client ID but with the hash of the ID (which is a hash of
147 the nickname) as well without any difference in performance.
149 Added also silc_idcache_find_by_id_one_ext to do one on one
150 searching when we have the actual ID. Added also function
151 silc_hash_client_id_compare. The affected files are
152 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
154 * When hashing the name associated with a ID it is always done
155 in lowercase. This way we can access the cache without worrying
156 about case-sensitivity, even though, for example nicknames are
159 * Fixed a bug in server with channel message sending. It put
160 wrong ID type as destination ID. The affected file
163 * silc_idcache_del_by_context now deletes from all hash tables
164 by context. Affected file lib/silccore/idcache.c.
166 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
168 * Changed the client library to use the new ID Cache interface.
169 Changes around the source tree.
171 * Added silc_hash_table_rehash_ext to rehash with specific
172 hash function. Affected file lib/silcutil/silchashtable.[ch].
174 * Added silc_hash_string_compare to compare two strings in the
175 hash table. Affected file lib/silcutil/silcutil.[ch].
177 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
179 * Added new function silc_idcache_del_by_context into the
180 lib/silccore/idcache.[ch].
182 * Changed the server's ID list routines to use the new ID Cache
183 interface. Changes around the source tree.
185 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
187 * Added silc_hash_table_del[_by_context]_ext functions in to the
188 lib/silcutil/silchashtable.[ch].
190 Removed silc_hash_table_find_all* routines and added new
191 silc_hash_table_find_foreach to replace them.
193 Added silc_hash_table_replace_ext function as extended
194 replacing function. Separated the simple hash table interface
195 from the extended hash table interface in the file
196 lib/silcutil/silchashtable.h.
198 * Fixed minor bugs and changed it to use some of the new
199 hash table functions in lib/silccore/idcache.c
201 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
203 * Added new function silc_hash_table_find_all to return all keys
204 in the hash table by the specified key. As the hash table is
205 collision resistant it also makes it possible to have several
206 duplicate keys in the hash table. This function may be used to
207 find all of the keys from the hash.
209 Added user_context arguments to the SilcHashFunction,
210 SilcHashCompare and SilcHashDestructor to deliver user specified
213 Added new fuctions silc_hash_table_find[_all]_ext to do
214 extended lookup with specified hash and compare functions and
215 specified user contexts.
217 Added new function silc_hash_table_add_ext to add the key
218 with specified hash function and user context.
220 Added new function silc_hash_table_foreach to traverse all
221 entrys in the hash table. Added SilcHashForeach callback
224 Added new function silc_hash_table_del_by_context to delete
225 the entry only if the context associated with the key matches.
227 Affected files are lib/silcutil/silchashtable.[ch].
229 * Removed silc_hash_[server/client/channel]_id and added just
230 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
231 silc_hash_id_compare to compare two ID's using as the hash table
232 comparison function. Added also silc_hash_data to hash
233 binary data and silc_hash_data_compare to compare it.
235 * Removed silc_idlist_find_client_by_hash as it is not needed
236 anymore. Affected file silcd/idlist.[ch].
238 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
239 to use internally the SilcHashTable. The new ID Cache is a lot
240 faster than the old one. Some of the ID Cache interface was also
241 rewritten and obsolete and stupid functions were removed.
243 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
245 * Added entry_count field to the SilcHashTable to keep the number
246 of the entries in the table. Implemented the function
247 silc_hash_table_rehash. Added new function
248 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
250 Fixed a minor bug in silc_hash_table_free.
252 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
253 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
254 into the lib/silcutil/silcutil.[ch].
256 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
258 * Implemented a collision resistant hash table into the
259 lib/silcutil/silchashtable[ch]. See the header and the source
260 for the SilcHashTable API.
262 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
264 * Merged dotconf version 1.0.2 into lib/dotconf.
266 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
268 * Do not compile anything in lib/silcsim/* if the SIM support
269 is not enabled. The tree should now compile without problems
272 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
274 * Compiled the SILC under cygwin. Compiled and tested briefly
275 without problems. More tests needed. The SIMs didn't compile
278 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
280 * Fixed possible crash in silc_get_username in the
281 lib/silcutil/silcutil.c.
283 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
285 * Fixed a va_arg in silc/client_ops.c.
287 * Oops, RC5 routines were named AES and caused some problems
288 when not using SIM's. Affected file lib/silccrypt/rc5.c.
290 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
292 * Added new SilcIDIP structure into the lib/silccore/id.h and
293 replaced the old `ip' fields from all SILC ID's to that type.
294 This is a step towards IPv6 support.
296 The silc_id_get_len takes now the ID as an extra argument.
297 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
298 both IPv4 and IPv6 based ID's.
300 The affected files are lib/silccore/id.[ch] and other files
301 around the tree using these routines.
303 * Removed the ID length arguments in server from various
304 silc_server_send_notify_* routines -> they are not needed
307 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
309 * Fixed memory leak in silc_encode_pem_file in the file
310 lib/silcutil/silcutil.c.
312 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
314 * Check minor version as well in the SKE. Affected files are
315 silcd/protocol.c and lib/silcclient/protocol.c.
317 * Added --identifier option to the server so that an identifier
318 can be when creating the public key for the server. Affected
319 file is silcd/silcd.c.
321 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
322 lib/silccrypt/silcpkcs.c.
324 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Register default ciphers and stuff when using -C option with
327 the server. Affected file sildc/silcd.c.
329 * Put back the servers public key filename format, it is better
330 than the new one. For now, the client keys are saved with the
331 new filename format. The affected file silc/client_ops.c.
333 * Implemented the Cipher API for the rest of the ciphers that
334 did not implement it or implemented it the wrong way.
336 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
338 * Register default ciphers and stuff when using the -S option
339 in the client. Affected file silc/silc.c. Same also when
340 creating new key pair with -C option.
342 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
344 * Fixed the silc_verify_public_key client operation function to
345 save the public keys differently. The fingerprint is now
346 used as filename and not the hostname. This way also the
347 client keys are saved uniquely and not with hostnames. The
348 affected file is silc/client_ops.c.
350 * Trimmed the silc_hash_fingerprint function to remove extra
351 whitespaces from the end of the fingerprint. The affected
352 file is lib/silccrypt/silchash.c.
356 * Added silc_cipher_register_default function to register all
357 default ciphers. It can be used when configuration files
358 does not exist and the application does not want any specific
359 ciphers in any specific order.
361 The SilcDList is now used as silc_cipher_list dynamically
362 allocated cipher list. Removed the static list all together
363 and now all ciphers must be allocated to the dynamic list.
364 The silc_cipher_alloc routine was changed to check only the
367 All silc_cipher_* routines that used to return int returns
370 The affected files lib/silccrypt/silccrypt.[ch].
372 * The same thing was done to silc_hash_* as for silc_cipher_*
373 routines. Affected files lib/silccrypt/silchash.[ch].
375 * The same thing was done to silc_pkcs_* as for silc_cipher_*
376 routines. Affected files lib/silccrypt/silcpkcs.[ch].
377 Added also silc_pkcs_[un]register[_default] functions.
378 Removed the data_context from the PKCS API.
380 * Added silc_hmac_register_default function to register default
381 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
382 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
383 to unregister all hmacs at once.
385 * Register the default ciphers, hash functions, PKCSs and HMACs
386 if client's configuration file does not exist. The affected
389 * The client did not load the hash functions from the SIM
390 modules at all. Added support for this. Affected file is
393 * When decoding public key with silc_pkcs_public_key_decode, check
394 the supported algorithm only if PKCS are registered. Affected
395 file lib/silccrypt/silcpkcs.c. The same was done with the
396 silc_pkcs_private_key_decode.
398 * Fixed the SILC List routines to keep the list always in order.
399 It used to change the list's order when traversing the list but
400 not it preserves the order. Affected file lib/trq/silclist.h.
402 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
404 * Added the client library to use the SilcSocketConnection's
405 reference counter (by silc_socket_dup) to prevent the bug that
406 the socket object may be freed underneath async operation.
408 * The name resolv library checking fixes in the configure.in.pre.
411 * Created new version of the protocol drafts for future
412 development. The -03 drafts are the ones that will be changed
413 in the trunk now and the -02 will remain as they are.
415 * Send list of CUMODE notifys to the router when announcing
416 the channel users to the router. Affected file silcd/server.c.
417 If the router receiving channel founder CUMODE for a channel
418 that already has channel founder it will send CUMODE notify
419 to the sender to remove the channel founder rights from the
420 announced client. Affected file silcd/packet_receive.c.
422 * The CUMODE notify may now use Server ID as well as the entity
423 who changes the mode. Updated protocool specs.
425 * Updated INSTALL and README files.
427 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
429 * New web pages in the http://silc.pspt.fi. The pages was
434 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
436 * Implemented the [DenyConnectin] config section in the server.
437 Added silc_server_config_denied_conn to check whether incoming
438 connection is denied. Affected file silcd/serverconfig.[ch].
440 * Do not check the ports when checking the incoming configuration
441 data if the port is 0, meaning any. Affected file is
442 silcd/serverconfig.c.
444 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
446 * Fixed buffer overflow in silc_string_compare in the file
447 lib/silcutil/silcutil.c.
449 * Fixed double free in silc_server_command_leave in the file
452 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Fixed the version checking in the server. Affected file is
457 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
459 * Fixed the configuration data fetching when accepting new
460 connections in the server. Affected file silcd/server.c.
462 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
464 * Added `sender_entry' argument to the function
465 silc_server_packet_relay_to_channel so that we can check
466 whether some destination actually belongs to the same route
467 the sender belongs (ie, we must not resend the packet to the
468 sender). Affected file silcd/packet_send.[ch].
470 * Added `servername' field to the SilcClientEntry in the server
471 to hold the name of the server where client is from. Affected
472 file is silcd/idlist.h.
474 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
476 * Moved the channel message encrypting in the router betwen
477 router connections from silc_server_channel_message to the
478 silc_server_packet_relay_to_channel since we want to check
479 whether we have anybody channel before encrypting anything.
480 Affected files silcd/packet_[receive/send].c.
482 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
484 * Fixed the [AdminConnection] server config section to support
485 multiple entries. Affected file silcd/serverconfig.c.
487 * Added support into the server to check the validity of the
488 incoming connection before executing any KE or authentication
491 * The connection configuration is now saved to the KE and
492 connection auth protocol contexts and not fetched anymore in
493 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
495 * The local hosts listenning address and port is also resolved
496 now when starting the server. We want to have the socket object
497 to include the real address and port for the listener. Added
498 new function silc_net_check_local_by_sock into the files
499 lib/silcutil/silcnet.[ch].
501 * Fixed a broadcast bug in server -> do not broadcast if we
504 * Fixed a routing bug. Do not route broadcast packets ever.
505 Broadcast packets must be processed always and not routed since
506 they may be destined to some other host than yourself and thus
507 would get routed without no good reason. Affected file is
510 * Added function silc_server_config_is_primary_route to check
511 whether primary router connection has been configured (a router
512 configuration that we are initiating). If there is not, we
513 will assume that there is only two routers in the SILC network
514 and we will use the incoming router connection as our primary
515 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
517 * Changed the order of the broadcasting. Broadcast _after_ the
518 packet has been processed not before. Affected file is
521 * Fixed a [ClientConnection] parsing bug. The port was never
522 parsed correctly thus resulting to port 0. Affected file
523 silcd/serverconfig.c.
525 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
526 argument and did not set the broadcast packet flag. Affected
527 file silcd/packet_send.c. Fixed same bug in the function
528 silc_server_send_notify as well.
530 * If we receive NEW_ID packet for our own ID in the server, ignore
533 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
537 * Removed the nickname from the Private Message Payload.
538 Updated the code and the protocol specs.
540 * Updated protocol specs for submitting to the IETF.
542 * Tweaked the Random Number Generator a bit. Affected file
543 lib/silccrypt/silcrng.c. Exported a new function
544 silc_rng_[global]_add_noise which can be used to add more
547 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
549 * Do not parse packets with different timeout when protocol
550 is active -> may cause problem with rekey. Affected file
553 * When server receives signoff notify it must not create
554 new channel key if the client is on any channels since the
555 sender of the signoff notify will create it.
557 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Added printing of error messages during SKE protocol from the
560 failure packet sent by server during SKE. Affected file
563 * Removed the client's failure_callback handling with timeout
564 and handle it immediately when received.
566 * The SKE library returned wrong type in SUCCESS and FAILURE
567 packets. They must be 32 bit MSB not 16 bit MSB.
569 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * Ok, rewrote the logic of the re-key and now it seems to work.
572 I tested it on high traffic with frequent re-keys without
573 problems. Added hmac_receive (and renamed hmac to hmac_send)
574 in SilcClientConnection in lib/silcclient/client.h and
575 in SilcIDListData in silcd/idlist.h. Also, removed the
576 SilcPacketParserContext's cipher and hmac fields as they are
577 not needed anymore and actually caused some problems when
578 the ciphers and hmac's changed underneath the packet parser.
580 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
582 * If re-key protocol is active then process the incoming packets
583 synchronously since we must assure that icoming packets encrypted
584 with the old key is processed before the new keys is set to
585 use. This is true other packets than for REKEY packets.
586 Affected file silcd/server.c. The same was done to client library
587 as well, affected file lib/silcclient/client.c.
589 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
591 * Fixed bug in client and server to accept the force send if
592 the packet is send from silc_[server/client]_packet_process
593 function. Otherwise the packets are never delivered, oops.
595 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
597 * Disable force sending of packets when REKEY protocol is active.
598 We must assure that no packet is sent directly when rekey is
599 performed. All packets must be sent through packet queue.
600 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
601 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
602 function is silc_[server/client]_packet_send_real to check
605 * Replaced the SIM paths from example config files to
606 /usr/local/modules. Also, make install creates now
607 /usr/local/silc/logs directory to hold all the SILC server
610 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
612 * Made the configure.in.pre work on Solaris. Patch by salo.
614 * Made all ciphers compatible with non-x86 machines. Defined
615 CBC mode macros into lib/silccrypt/ciphers_def.h.
617 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Fixed the make install.
621 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * When MAC computation fails the silc_packet_decrypt returned 0
624 even though it was supposed to return -1. Fixed this. The
625 affected file is lib/silccore/silcpacket.c.
627 * Do not replace the config files in /etc/silc (in make install)
628 if they already exist. Affected file ./Makefile.am.
630 * Do not send re-key packets immediately but through packet queue.
631 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
633 * Changed silc_net_check_host_by_sock to return FALSE if the
634 IP/DNS could not be resolved. Though, it returns the IP address
635 now even if it could not resolve it (but returns also FALSE).
636 Affected file lib/silcutil/silcnet.[ch].
638 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Added silc_pkcs_decode_identifier to decode the public key's
641 identifier. Affected file lib/silccrypt/silpkcs.[ch].
642 Added also silc_pkcs_free_identifier. Added also new context
643 SilcPublicKeyIdentifier.
645 * Added -S option to the silc client. It is used to dump the
646 contents of the specified public key file.
648 * Changed the PKCS api to return the public key length when
649 setting the public key.
651 * Fixed a fatal bug in the public and private key file loading.
652 Affected file lib/silccrypt/silcpkcs.c.
654 * Execute the packet parsing for client with zero (0) timeout
655 if the protocol is active. Affected file silcd/server.c.
657 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
659 * Made the key generation options to the silcd program. Added
660 -C option, equivalent to client's option.
662 * Added new [ServerKeys] config section to the server. It
663 configures the server's public and private key.
665 * Defined generic Public Key Payload into the protocol
666 specification to send specific type of public keys and
669 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
670 public key or certificate.
672 * Implemented the GETKEY command to the server and to the
673 client library and on user interface.
675 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
677 * Made preliminary `make install' work.
679 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
681 * Added SilcServerRekey context into silcd/idlist.h.
683 * Added the PFS support as defined in the specification to the
684 SKE protocol. Affected files lib/silcske/*.c.
686 * Added `ske_group' field to the SilcServerRekey context to hold
687 the number of the SKE group that is used with PFS in re-key.
688 Affected file silcd/idlist.h.
690 * Added PFS re-key support to the server. Affected file is
693 * Added silc_protocol_cancel to cancel execution of the next
694 state of the protocol. Affected file is
695 lib/silccore/silcprotocol.[ch].
697 * Added the re-key support with and without PFS to the client
698 library. Re-key is performed once in an hour, by default.
700 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
701 Added silc_client_rekey_callback and silc_client_rekey_final.
702 Affected files are lib/silcclient/protocol.[ch] and
703 lib/silcclient/client.[ch].
705 * Removed the `hmac_key' and `hmac_key_len' fields from the
706 SilcClientConnection structure; not needed. Affected file is
707 lib/silcclient/client.h.
711 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
713 * Do not ask whether user wants to use the negotiated private key
714 for private messages, just use it. Affected file is
715 silc/local_command.c.
717 * Added `send_enc_key' and `enc_key_len' fields to the
718 SilcIDListData structure since they are needed in the re-key
719 phase. Affected file is silcd/idlist.[ch].
721 * Implemented the simple re-key protocol into the server.
722 Affected files silcd/server.c and silcd/protocol.[ch]. The
723 re-key will be performed once in an hour, by default.
725 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
726 Added silc_server_rekey, silc_server_rekey_callback and
727 silc_server_rekey_final.
729 * Removed Tunneled flag from the protocol. Updated the code
730 and the specifications.
732 * Adde `pfs' field to the SilcIDListData to indicate whether
733 the PFS is to be performed in the re-key. Affected file is
736 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
738 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
739 int64 of at least the xintXX size. If void * is less that 4
740 bytes uint32 * will be used. Defined bool as boolean.
742 * Changed _ALL_ unsigned long and unsigned int to uint32,
743 unsgined short to uint16 in the source tree.
745 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
746 not handle clients that has entry->data.registered == FALSE.
747 They are not in the network anymore. Affected file is
750 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
752 * Implemented the sending of the SERVER_SIGNOFF notify in the
753 server. Affected file is silcd/server.c.
755 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
756 Added also silc_notify_payload_encode_args into the
757 lib/silccore/silcnotify.[ch].
759 * Implemented ther SERVER_SIGNOFF notify handling in the server.
760 Affected file silcd/packet_receive.c.
762 * Implemented the SERVER_SIGNOFF notify handling in the client
763 library. Affected file lib/silcclient/client_notify.c. Also,
764 implemnted the printing of the SERVER_SIGNOFF info to the
765 application. Affected file silc/client_ops.c.
767 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
768 if the deleting was successful. Affected file silcd/idlist.[ch].
770 * Added support for public key authentication in the connection
771 authentication protocol in the client library. Affected file
772 lib/silcclient/protocol.c.
774 * Changed the server's silc_idlist_get_clients_by_* interface
775 to support already allocated array so that new entries may be
776 added to pre-allocated array. Affected file silcd/idlist.[ch].
777 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
780 * All command reply functions in the server now calls the
781 pending command callback even if error occured. This way the
782 error will be delivered to the client as well. Affected files
783 silcd/command.c and silcd/command_reply.c.
785 * Fixed INFO command to return local server's info if no server
786 was provided. Affected file lib/silcclient/command.c.
788 * Removed RESTART command for good. Updated the code and the
791 * Rewrote parts of the task system. It is a bit simpler now.
792 Removed unsued task priorities. The affected files are
793 lib/silcutil/silctask.[ch].
795 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
797 * Moved the USERS printing from the library to the application.
798 Affected files lib/silcclient/command.c and silc/client_ops.c.
800 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
804 * Added channel key re-key support. The re-key is perfomed
805 only by the router and is done once in an hour. Added `rekey'
806 field to the SilcChannelEntry in the server. Affected files
807 silcd/server.c and silcd/idlist.h.
809 * Added silc_task_unregister_by_context into the file
810 lib/silcutil/silctask.[ch].
812 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
814 * Added SILC_UMODE_GONE mode to indicate when the client is not
815 present in the SILC network. Added also support to the local
816 command AWAY that will set this mode. Added support of showing
817 "xxx is gone" in WHOIS command. The USERS command shows the
820 * Fixed setting server and router operator privileges in the
821 server's UMODE command. Affected file silcd/command.c.
823 * Merged the SKE KE1 and KE2 payloads into one payload. The
824 new KE payload is equivalent to the old KE2 payload.
826 Cleaned up the SKE Start Payload parsing. It now uses the
827 simple buffer unformatting to do the parsing. A lot faster
830 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
831 to the SKE that is used to indicate whether both of the SKE
832 parties should perform authentication. By default only the
833 responder performs authentication. By setting this flag also
834 the initiator must do authentication. By default it is unset
835 since in normal SKE case, client to server connection, only
836 the responder should do authentication. When doing SKE between
837 two clients both should perform authentication. Updated the
838 code and the protocol specs.
840 * A little fix to IDENTIFY command in the server. Search the
841 client first by hash not nickname. Affected file is
844 * Fixed the silc_client_close_connection to support closing
845 the client to client connections wihtout deleting too much
846 data. Affected file lib/silcclient/client.c.
848 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
849 are received if protocol used to be active but is not anymore
850 the application would crash due to NULL pointer dereference.
851 Affected files silcd/server.c and lib/silcclient/client.c.
853 * Added `hash' field to the SilcClientConnection to include
854 the hash function negotiated in the SKE protocol.
856 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
857 to set the channel founder authentication data. A client can
858 claim the founder rights later by providing the authentication
859 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
860 This way the channel founder can regain the channel founder
861 privileges even it is left the channel. This works only on
862 local server and the client must be connected to the same
863 server to be able to regain the founder rights. Updated the
864 protocol specs accordingly.
866 Added support to the CMODE command in the client to set the
867 founder auth data. Read the README to see how to set it.
869 Added support to the CUMODE command to claim the founder
870 rights. Read the README to see how to do it.
872 Added support for the founder authentication to the Channel
873 Entry in the server. Affected file silcd/idlist.h.
875 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
876 server's CMODE command. Affected file silcd/command.c.
878 * Added the following new functions into lib/silccore/silcauth.[ch]:
879 silc_auth_get_method and silc_auth_get_data.
881 * The server now saves the remote hosts public key to the
882 SilcIDListData pointer. Affected file silcd/protocol.c.
884 * The normal server now does not remove the channel entry from
885 the cache if the founder authentication data is set. It used
886 to remove it if the founder was the last one on the channel on
887 the server and left the channel. The auth data is saved and
888 if the channel is re-joined later the old entry is used with
889 the old auth data. Affected files silcd/command_reply.c and
892 * Removed the `pkcs' field from the SilcIDListData structure
893 in the server; it is not used. Affected file silcd/idlist.h.
895 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
897 * Fixed packet processing on slow links. Partial packets were
898 never re-processed because the incoming data buffer was cleared
899 by the application. Application must not directly clear the
900 sock->inbuf, the packet processing routines handle it. Fixed
901 this in client library and in server.
903 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
905 * Fixed the WHOIS and IDENTIFY send reply function to really
906 check whether to send list or just one entry. Affected file
909 * Cleaned up the LEAVE command's channel key distribution. The
910 affected file silcd/command.c.
912 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
913 can enforce the channel mode as well. In that case the ID
914 includes the ID of the server. The code now enforces the
915 mode change if the router have different mode than the server.
917 * The notify client operation with CMODE_CHANGE notify can now
918 return NULL client_entry pointer if the CMODE was not changed
919 by client. Application must check for this.
921 * Added <Server ID> argument to INFO command to support server
922 info fetching by Server ID.
924 * Added silc_server_announce_get_channel_users to get assembled
925 packets of channel users of the specified channel. Affected
926 file silcd/server.[ch].
928 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
929 was freed underneath the ID Cache.
931 * Re-announce clients when the server received CHANNEL_CHANGE
932 notify from the router. Affected file silcd/packet_send.c.
934 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
936 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
937 crashed since it did not handle the fact that there is no cipher
938 called "3" and didn't check the error condition. Now fixed.
940 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
941 flag. It can be used to send message requests.
943 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Implemented the RESTART command in the client.
947 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
948 notice type messages. Added notice printing to the user
951 * The channel keys are not re-generated if the channel's mode
952 is PRIVKEY, ie private key on the channel exists. Affected
953 files silcd/server.c and silcd/command.c.
955 * Fixed a little bug in channel message delivery when channel
956 private keys are set in the server. Affected file is
959 * Changed the setting on channel->on_channel = TRUE from the
960 silc_client_save_channel_key to the JOIN command reply. The
961 key payload is not received if the private channel key is set.
962 Affected file lib/silcclient/command_reply.c and the
963 lib/silcclient/client_channel.c.
965 * When the CMODE_CHANGE notify is sent and the channel private
966 key mode is removed the channel key must be re-generated in
967 other cells as well. Added this support for the router in the
968 silcd/packet_receive.c.
970 * Added new local command NOTICE to send notice message on
971 channel. Affected file silc/local_command.[ch].
973 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
975 * Added new local command ME to the client. It is used to send
976 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
977 some action. Affected file silc/local_command.[ch].
979 * Changed channel_message and private_message client operations
980 to deliver the message flags to the application. Added also
981 the `flags' arguments to the silc_client_send_channel_message
982 and silc_client_send_private_message functions. Affected file
985 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Redefined the Private Message Payload to support private message
988 keys and to support the new private message flags. Updated
989 the protocol specs. Flags makes it possible to have for example
992 * Added new type SilcPrivateMessagePayload and defined an API
993 for it in the lib/silcclient/silcprivate.[ch].
995 * Tested private message private keys successfully. Tested the
996 private message key set, unset and list commands with the new
999 * Redefined the Channel Message Payload to include the channel
1000 message flags (equal with private message flags) to support
1001 for example CTCP style messages.
1003 * Defined some of the message (for channel and private message)
1004 flags. Updated the protocol specs and added the flags to the
1005 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1007 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Added SilcKeyAgreementStatus type to the key agreement routines
1010 to indicate the current status and error if one occured.
1011 The status types are defined in the lib/silcclient/silcapi.h.
1013 * Added new local command KEY that is used to set and unset private
1014 keys for channels, set and unset private keys for private messages
1015 with remote clients and to send key agreement requests and
1016 negotiate the key agreement protocol with remote client. The
1017 key agreement is supported only to negotiate private message keys,
1018 it currently cannot be used to negotiate private keys for channels,
1019 as it is not convenient for that purpose.
1021 * Fixed a minor pending callback setting bug in the function
1022 silc_client_get_client_by_id_resolve, now the function works.
1023 Affected file lib/silcclient/idlist.c.
1025 * Added function silc_net_get_local_port to get local bound
1026 port by socket. Added to lib/silcutil/silcnet.[ch].
1028 * Added `sockets' and `sockets_count' fields to the SilcClient
1029 object. They hold the sockets of the listenning sockets in
1030 the client. Listenning sockets may be for example the key
1031 agreement server. Affected file lib/silcclient/client.[ch].
1032 Added functions the silc_client_add_socket and the
1033 silc_client_del_socket. They are exported to the application
1036 * Added ~./silc/clientkeys to support other client's public keys.
1038 * Renamed verify_server_key client operation to verify_public_key
1039 and added one argument to indicate the type of the connection
1040 (server, client etc.).
1042 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1044 * Added silc_server_connection_auth_request to handle the
1045 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1046 silcd/packet_receive.[ch].
1048 * Added silc_server_send_connection_auth_request into the
1049 silcd/packet_send.c to send the connection auth request packet.
1051 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1054 * Fixed the public key authentication in responder side in the
1055 server. The `auth_data' pointer includes the SilcPublicKey
1056 not the path to the public key. Affected file silcd/protocol.c.
1058 * Implemented the public key authentication in the initiator side
1059 in the server. Affected file silcd/protocol.c.
1061 * Removed the [RedirectClient] config section from the server
1062 configuration. Is not needed and I don't want to implement it.
1064 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1066 * Cleaned up the CMODE command in the server. It now works
1067 correctly and supports all the modes defined in the protocol.
1068 Affected file is silcd/command.c.
1070 * Added `hmac_name' field to the SilcChannelEntry in the server
1071 to hold the default HMAC of the channel. It can be set when
1072 creating the channel (with JOIN command). Affected files
1075 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1076 type to indicate the change of the current cipher and hmac
1077 on the channel. Client can safely ignore the <cipher> argument
1078 (if it chooses to do so) since the CHANNEL_KEY packet will
1079 force the channel key change anyway. The <hmac> argument is
1080 important since the client is responsible of setting the new
1081 HMAC and the hmac key into use.
1083 * Fixed the CMODE command in the client library as well.
1085 * Tested CMODE command in router environment successfully.
1087 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1089 * Show the version of the remote client (or server) when connecting
1090 to the server. It is logged to the log file. Affected file
1091 is silcd/protocol.c.
1093 * Fixed the KILLED notify handling in the client library. The
1094 client must be removed from all channels when receiving the
1097 Also, do not remove the client entry when giving the KILL
1098 command but when the KILLED notify is received.
1100 * Removed silc_idlist_find_client_by_nickname from the server.
1101 Not needed anymore. Affected files silcd/idlist.[ch].
1103 * Implemented the CHANNEL_CHANGE notify type handling to the
1104 server. Affected file silcd/server.c.
1108 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1110 * Added silc_server_send_notify_invite to send the INVITE
1111 notify between routers.
1113 * Implemented the INVITE command correctly to the server.
1115 * Implemented the INVITE notify type handling in the server.
1117 * Implemented the INVITE command to the client library and on the
1120 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1122 * Added function silc_server_get_client_resolve to find the
1123 client entry by ID from all ID lists and then resolve it
1124 (using WHOIS) if it cannot be found. Affected file is
1127 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1129 * Implemented the BAN command to the client library.
1131 * The JOIN command in the server now checks the invite list
1134 * Changed the silc_command_reply_payload_encode_va and the
1135 silc_command_payload_encode_va to support that if argument is
1136 NULL it ignores and checks the next argument. Affected file
1137 lib/silccore/silccommand.c.
1139 * Added silc_server_send_notify_ban to send the BAN notify
1140 type between routers.
1142 * Chaned the silc_notify_payload_encode to support that if
1143 argument is NULL it ignores and checks the next argument.
1144 Affected file lib/silccore/silcnotify.c.
1146 * Tested ban lists in router environment successfully.
1148 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1150 * Implemented BAN command to the server, in silcd/command.[ch].
1152 * Removed the BAN and INVITE_LIST modes from the CMODE command
1155 * Added function silc_string_match to regex match two strings.
1156 Affected files lib/silcutil/silcutil.[ch].
1158 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1160 * Redefined parts of the SilcChannelEntry in the server to support
1161 the new ban and invite lists.
1163 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1165 * Redefined the INVITE command. The same command can be used to
1166 invite individuals to the channel but also to manage the invite
1167 list of the channel (to add to and remove from the invite list).
1168 Updated the protocol specs.
1170 * Added new command SILC_COMMAND_BAN that can be used to manage
1171 the ban list of the channel. Updated the protocol specs.
1173 * Removed the channel modes: the SILC_CMODE_BAN and the
1174 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1175 in the CMODE command. The equivalent features are now available
1176 using INVITE and BAN commands. Updated the protocol specs.
1178 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1179 in the network about change in the current ban list. The notify
1180 type is not used by the client.
1182 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1183 support the invite lists.
1185 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * Added new function silc_string_regexify that converts string
1188 including wildcard characters into regex string that can
1189 be used by the GNU regex library. Added into the file
1190 lib/silcutil/silcutil.[ch].
1192 Added silc_string_regex_combine to combine to regex strings
1193 into one so that they can be used as one regex string by
1194 the GNU regex library. Added into the file
1195 lib/silcutil/silcutil.[ch].
1197 Added silc_string_regex_match to match two strings. It returns
1198 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1200 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1202 * Imported GNU regex to the soruce tree into lib/contrib.
1203 Fixed some compiler warning from the regex.c.
1205 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Fixed MOTD command in the server to work in router environment.
1209 * Fixed the MOTD command in the client library to support
1210 the server argument in the command.
1212 * Added `nickname_len' argument to the silc_idlist_add_client
1213 in the server, as the `nickname' argument may be binary data
1216 * Added silc_idlist_get_channels to return all channels from
1219 * Implemented LIST command to the server. Affected file is
1222 * Implemented the LIST command to the client library and on the
1225 * Added [<user count>] argument to the LIST command reply.
1226 With private channels the user count is not shown.
1228 * Updated TODO and README.
1230 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1232 * The client entry's data.registered must be TRUE even with
1233 global client entry on global client list. The data.registered
1234 is used to check whether the client is anymore in the network,
1235 for example with WHOWAS command so it must be valid.
1237 * Fixed the WHOWAS command in the server. It now actually works
1238 in router environment. Added function into silcd/command_reply.c
1239 silc_server_command_reply_whowas_save.
1241 * Added silc_idlist_purge function to the silcd/idlist.c
1242 to periodically purge the ID Cache.
1244 * Fixed INFO command in the server. It works now in router
1245 environment. Added <server name> argument to the INFO command
1246 reply. Updated the protocol specs.
1248 * Fixed minor bug in silc_idcache_purge to not purge if the
1249 expire value is zero.
1251 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1252 they were buggy because of the WHOWAS information.
1254 * Fixed local command MSG to handle the async resolving of
1255 the remote client properly. It used to fail the first MSG.
1256 Affected file silc/local_command.c.
1258 * Added `data_len' field to SilcIDCache context.
1260 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Update TODO. Todo in commands in the server.
1264 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1266 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1267 used by routers as broadcast packet to inform other routers
1268 about the changed user mode.
1270 Implemented the notify handling in the server. Affected file is
1271 silcd/packet_receive.c. Added the function
1272 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1274 * Added new generic Channel Payload and deprecated the New Channel
1275 Payload. The New Channel Payload is now the generic Channel
1278 * Added new argument `mode' to the silc_server_send_new_channel
1279 as it is required in the Channel Payload now.
1281 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1282 and created a new and real SilChannelPayload to represent the
1283 new generic Channel Payload. Implemented the encode/decode
1284 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1286 * Added silc_server_get_client_channel_list to return the list
1287 of channels the client has joined for WHOIS command reply.
1288 Affected file silcd/server.[ch].
1290 * Implemented the channel list sending in the WHOIS command reply
1291 in server and in the client.
1293 Implemented the channel list displaying on the user interface
1294 as well. Affected file silc/client_ops.c.
1296 * Added silc_channel_payload_parse_list to parse list of Channel
1297 Payloads. It returns SilcDList list of SilcChannelPayloads.
1298 Client for example can use this function to parse the list of
1299 channels it receives in the WHOIS command reply. The caller
1300 must free the list by calling silc_channel_payload_list_free.
1301 Affected files lib/silccore/silcchannel.[ch].
1303 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1305 * Added one new argument <user mode> to the WHOIS command reply
1306 to return the mode of the user in SILC. Updated the protocol
1309 Implemented it to the server and client.
1311 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1313 * Fixed the mode printing on the user interface on joining.
1314 Affected file silc/client_ops.c.
1316 * Implemented the UMODE command and user modes in general to the
1317 client library and to the user interface.
1319 * Implemented the UMODE command to the server.
1321 * The server now sends UNKNOWN_COMMAND error status if client sends
1322 unknown command. Affected file silcd/command.c.
1324 * All server commands now handle the command identifier the right
1325 way when sending the command reply to the client. The client can
1326 use to identify the command replies with the identifier.
1328 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1330 * Added silc_server_get_client_route to resolve the route to
1331 the client indicated by the client ID. Affected file is
1334 * Added silc_server_relay_packet as general function to relay
1335 packet to arbitrary destination. This deprecates functions
1336 like _send_private_message_key, _relay_notify etc. Affected
1337 file is silcd/packet_send.[ch].
1339 Removed silc_server_send_key_agreement,
1340 silc_server_send_private_message_key and
1341 silc_server_packet_relay_notify functions from the file
1342 silcd/packet_send.[ch].
1346 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1347 server. Affected file silcd/packet_receive.[ch].
1349 * Implemented the KILL command to the client. Implemented the
1350 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1351 Affected files lib/silcclient/command[_reply].c and
1352 lib/silcclient/client_notify.c. Implemented the KILL notify
1353 printing in the user inteface.
1355 * Fixed a lot silc_parse_nick memory leaks from the client
1356 library in the file lib/silcclient/command.c.
1358 * Changed the silc_server_send_notify_on_channels's `sender'
1359 argument from SilcSocketConnection to SilcClientEntry to
1360 check the sender as entry and not as connection object and not
1361 to send to the client provided as argument. The affected file
1362 is silcd/packet_send.[ch].
1364 * The notify packets that are destined directly to the client used
1365 to not to be processed by the server. Now changed that and the
1366 server processes all notify packets. After relaying the packet
1367 to the client the notify packet is processed in the server.
1369 * The silc_server_free_client_data now checks whether there is
1370 pending outgoing traffic for the client and purges the data to
1371 the network before removing the client entry.
1373 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1375 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1376 an client is killed from the SILC Network. Updated the protocol
1379 Added new function silc_server_send_notify_killed to the
1380 silcd/packet_send.[ch].
1382 * Added function silc_server_packet_relay_notify to relay notify
1383 packets that are destined directly to a client. In this case
1384 the server does not process the notify packets but merely relays
1385 it to the client. Affected file silcd/packet_send.[ch].
1387 Added also silc_server_packet_process_relay_notify to check
1388 whereto relay the notify. Affected file is
1389 silcd/packet_receive.[ch].
1391 * Implemented the KILL command to the server.
1395 * Added the backup schema desgined last fall to the protocol
1396 specs for everyone to see. The specification is in the
1397 *-spec-xx.txt draft and the packet type definitions for the
1398 backup routers is in *-pp-xx.txt draft. Thusly, added also
1399 new packet type SILC_PACKET_CELL_ROUTERS.
1401 * A big security problem in the implementation discovered. The
1402 signoff of an client did not cause new channel key generation
1403 which it of course should've done. The channel keys must be
1404 always re-generated when client leaves (or signoffs) the channel.
1405 The silc_server_remove_from_channels funtion now handles
1406 the channel key re-generation.
1408 * Added `sender' argument to the silc_server_send_notify_on_channels
1409 to not to send the client provided as argument. Affected file
1410 silcd/packet_send.[ch].
1412 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1414 * Implemented OPER and SILCOPER commands into the server and
1417 * Added silc_auth_verify and silc_auth_verify_data to verify
1418 the authentication directly from the authentication payload.
1419 It supports verifying both passphrase and public key based
1420 authentication. Affected file lib/silccore/silcauth.[ch].
1422 * Added `hash' field to the SilcIDListData structure. It is the
1423 hash negotiated in the SKE protocol. Affected file is
1426 * Slight redesigning of the SilcAuthPayload handling routines.
1427 Do not send SilcPKCS but SilcPublicKey as argument.
1429 * Implemented the public key authentication support to the
1430 serverconfig. The public key is loaded from the provided path
1431 and saved as authentication data to void * pointer. Thus,
1432 changed the unsigned char *auth_data to void *auth_data;
1434 * Fixed SHUTDOWN command to send the reply before the server
1435 is shutdown. :) Affected file silcd/command.c.
1437 * Fixed fatal bug in CONNECT command. The hostname was invalid
1438 memory and server crashed. Affected file silcd/command.c.
1440 * Fixed fatal bug in CLOSE command. The server_entry became
1441 invalid but was referenced later in the command. Affected file
1444 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1446 * Fixed fatal bug in failure packet handling. Server ignored
1447 the failure and thus crashed when it came.
1451 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1453 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1454 that the command may be executed only once in (about) 2 seconds.
1455 The old SILC_CF_LAG flag is same but allows command bursts up
1456 to five before limiting.
1458 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1459 server code. Various commands now includes the CF_LAG_STRICT
1460 flag to disallow any kind of miss-use of the command.
1462 * Fixed the silc_buffer_unformat to not to allocate any data
1463 if the length of the data is zero. It used to allocate the
1464 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1466 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1468 * Changed the format of AdminConnection configuration section
1469 in the server. Added username of the admin to the format.
1470 Affected files silcd/serverconfig.[ch].
1472 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1473 to return admin configuration data by host, username and/or
1476 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1478 * Implemented WHOWAS command to the server. Added the functions:
1480 silc_server_command_whowas_parse,
1481 silc_server_command_whowas_send_reply,
1482 silc_server_command_whowas_from_client and
1483 silc_server_command_whowas_from_server
1485 * Added <Client ID> argument to the WHOWAS command reply. Updated
1486 the protocol specs accordingly.
1488 * Implemented WHOWAS command and command_reply to the client
1491 Implemented the WHOWAS printing on the user interface.
1493 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1495 * Added new argument to the WHOWAS command reply, the real name.
1496 It is an optional argument. Updated the protocol specs.
1498 * Added SilcIDCacheDestructor callback that is registered when
1499 the SilcIDCache is allocated. The callback is called when
1500 an cache entry in the ID Cache expires, or is purged from the
1501 cache. Added into lib/silccore/idcache.[ch].
1503 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1504 to destruct the client entries when the cache entry expires.
1505 Other ID Cache's in server and in the client library ignores
1508 * If the ID Cache entry's `expire' field is zero then the entry
1509 never expires. Added boolean `expire' argument to the
1510 silc_idcache_add function in the lib/silccore/idcache.[ch].
1511 If it is TRUE the default expiry value is used.
1513 * Added silc_server_free_client_data_timeout that is registered
1514 when client disconnects. By default for 5 minutes we preserve
1515 the client entry for history - for WHOWAS command.
1517 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1519 * Added support to the server to enforce that commands are not
1520 executed more than once in 2 seconds. If server receives
1521 commands from client more frequently, timeout is registered
1522 to process the commands. Affected file silcd/command.c.
1523 Added new function silc_server_command_process_timeout.
1525 * Changed NICK_NOTIFY handling in client library to check that
1526 if the client's nickname was changed, so there is no need to
1527 resolve anything from the server.
1529 * Removed error printing from the WHOIS and IDENTIFY commands.
1530 If error occurs then it is ignored silently in the client library.
1531 The application, however, may map the received error to
1532 human readable error string. The application currently maps
1533 the NO_SUCH_NICKNAME error to string.
1535 * Made the command status message public to the application. Moved
1536 them from lib/silcclient/command_reply.c to
1537 lib/silcclient/command_reply.h. The application can map the
1538 received command status to the string with the
1539 silc_client_command_status_message function.
1541 * Added check to the server to check that client's ID is same
1542 as the Source ID in the packet the client sent. They must
1545 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Added dist-bzip hook to the Makefile.am to make bzip2
1548 compressed distributions.
1550 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1552 * Server now enforces the maximum length for the nickname and
1553 the channel as protocol specification dictates. 128 bytes for
1554 nickname and 256 bytes for channel name.
1556 * Moved the WHOIS printing to the application. The client libary
1557 does not print out the WHOIS information anymore, the application
1558 must do it. Renamed silc_client_command_reply_whois_print to
1559 the silc_client_command_reply_whois_save.
1561 The client's idle time is also sent to the application now, and
1562 the idle is shown on screen.
1564 * Added silc_client_command_reply_identify_save to save the
1565 received IDENTIFY entries.
1567 * Do not check for channel private keys in message sending and
1568 reception if the channel does not have the PRIVKEY mode set.
1569 Affected file lib/silclient/client_channel.c.
1571 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1573 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1574 just surfaced after chaning the JOIN procedure.
1576 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Added silc_client_get_clients_by_list to get client entries
1579 from Client ID list, that is returned for example by JOIN
1580 and USERS command replies. The application should use this
1581 function for example when JOIN command reply is received to
1582 resolve the clients already on the channel (library does not
1583 do that anymore as USERS command reply is not used in the JOIN
1584 procedure anymore). Affected files lib/silcclient/silcapi.h and
1585 lib/silcclient/idlist.c.
1587 * JOIN command reply and USERS command reply returns now SilcBuffer
1588 pointers instead of unsigned char pointers when returning
1589 the client list and mode list.
1591 * Added <Client ID> argument to the JOIN command reply, mainly
1592 for the server to identify for which client the command was
1593 originally sent. Updated protocol specs accordingly.
1595 * Added SilcDlist private_key pointer to the SilcChannelEntry
1596 in the client to support the channel private keys. Affected
1597 file is lib/silcclient/idlist.h.
1599 * Added SilcChannelPrivateKey argument to the function
1600 silc_client_send_channel_message so that application can choose
1601 to use specific private ke if it wants to. If it is not provided,
1602 the normal channel key is used, unless private keys are set.
1603 In this case the first (key that was added first) is used
1604 as the encryption key.
1606 * Implemented the support for channel private key handling.
1607 Implemented the following functions:
1609 silc_client_add_channel_private_key,
1610 silc_client_del_channel_private_keys,
1611 silc_client_del_channel_private_key,
1612 silc_client_list_channel_private_keys and
1613 silc_client_free_channel_private_keys
1615 Affected file lib/silcclient/client_channel.c.
1617 * Added the support for the private keys in the channel message
1618 sending and encryption and in the message reception and
1619 decryption. Affected funtions are
1620 silc_client_send_channel_message and silc_client_channel_message.
1622 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1624 * Added SKE's key verify callback to the client library's
1625 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1627 * Removed the statement that server (or router) must send USERS
1628 command reply when joining to the channel so that the client
1629 knows who are on the channel. Instead, the client list and
1630 client's mode list is now sent in the JOIN command reply to the
1631 client who joined channel. This is better solution.
1633 * Added function silc_server_get_users_on_channel and function
1634 silc_server_save_users_on_channel to the silcd/server.[ch].
1636 * Removed function silc_server_command_send_users from the
1639 * Do not show topic on the client library anymore. The topic is
1640 sent in the command reply notify to the application and the
1641 application must show the topic now.
1643 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Added client searching by nickname hash into the IDENTIFY and
1646 WHOIS commands in the server as they were clearly missing from
1647 them. Affected file is silcd/command.c.
1649 * Fixed a bug in private message receiving in the client library.
1650 The remote ID was freed and it wasn't supposed, now it is
1653 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Minor fix to the channel payload; allocate the data area, as it
1656 needs to be of specific length.
1658 * If the key agreement port is zero then the operating
1659 system will define the bound port. Affected files are
1660 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1662 * Added new function silc_channel_payload_decrypt into the file
1663 lib/silccore/silcchannel.[ch].
1665 * Moved the channel message etc, check from silc_packet_decrypt
1666 to applications. The library calls now a generic
1667 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1668 when the packet is either normal or special. This was done to
1669 allow more wide range of checking that was not allowed when
1670 the code was in library. Now applications can do virtually any
1671 checks to the packet and return to the library the decision how
1672 the packet should be processed. Affected files are
1673 lib/silccore/silcpacket.[ch].
1675 Added silc_server_packet_decrypt_check to the server and
1676 silc_client_packet_decrypt_check to the client library.
1678 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1679 to send with specified source and destination information.
1681 * Channel message delivery between routers was broken after the
1682 channel key distribution was fixed earlier. The channel key
1683 was used be to distributed to other routers as well which is not
1684 allowed by the protocol. Now this is fixed and channel keys
1685 really are cell specific and the channel message delivery between
1686 routers comply with the protocol specification.
1688 * Fixed various commands in server to check also the global list
1689 for the channel entry and not just the local list. The affected
1690 file silcd/command.c.
1692 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * Added assert()s to buffer formatting and unformatting routines
1695 to assert (if --enable-debug) when error occurs. Affected
1696 file: lib/silcutil/silcbuffmt.c.
1698 * Changed to auto-reconnect to check whether the remote host is
1699 router and register the re-connect timeout if it is. It used
1700 to check that whether we are normal server, but router must do
1701 auto-reconnect with another router as well. Affected file
1704 * Removed the [<key len>] option from CMODE command as the cipher
1705 name decides the key length, nowadays. See the defined ciphers
1706 from the protocol specification.
1708 * Added [<hmac>] option to the CMODE command to define the HMAC
1709 for the channel. Added SILC_CMODE_HMAC channel mode.
1711 * Added [<hmac>] option for the JOIN command so that user can
1712 select which HMAC is used to compute the MACs of the channel
1715 * Added Hmac field to the Channel Message Payload. The integrity
1716 of plaintext channel messages are now protected by computing
1717 MAC of the message and attaching the MAC to the payload. The
1718 MAC is encrypted. Now, it is clear that this causes some
1719 overhead to the size of the packet but rationale for this is that
1720 now the receiver can verify whether the channel message decrypted
1721 correctly and also when private keys are set for the channel the
1722 receiver can decrypt the packet with several keys and check from
1723 the MAC which key decrypted the message correctly.
1725 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1726 lib/silccrypt/silccipher.[ch].
1728 * Added silc_hash_len to return the digest length into the
1729 lib/silcrypt/silchash.[ch].
1731 * Rewrote parts of Silc Channel Payload interface in the
1732 lib/silccore/silcchannel.[ch]. The encode function now also
1733 encrypts the packet and parse function decrypts it.
1735 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1737 * Fixed a minor formatting bug in the SKE's key material processing.
1738 It actually might have processed the keys wrong way resulting
1741 * Redefined the mandatory HMAC algorithms and added new algorithms.
1742 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1743 and hmac-md5 truncated to 96 bits. The mandatory is now
1744 hmac-sha1-96. Rest are optional (including the one that used
1745 to be mandatory). Rationale for this is that the truncated HMAC
1746 length is sufficient from security point of view and can actually
1747 make the attack against the HMAC harder. Also, the truncated
1748 HMAC causes less overhead to the packets. See the RFC2104 for
1751 * Added new [hmac] configuration section. The SKE used to use
1752 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1753 is of course wrong. The official names that must be proposed in
1754 the SKE are the ones defined in the protocol specification
1755 (hmac-sha1-96 for example). The user can configure any hmac
1756 using any hash function configured in the [hash] section. At
1757 least, the mandatory must be configured.
1759 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1761 * Added HMAC list to the SKE proposal list. It has now both
1762 hash algorithm list and HMAC list. This makes the protocol
1763 incompatible with previous versions. The SKE now seems to work
1764 the way it is supposed to work, for the first time actually.
1766 * Defined plain Hash algorithms to the protocol specification.
1769 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1771 * Implemented support for key agreement packets into the server.
1772 Added functions silc_server_key_agreement and
1773 silc_server_send_key_agreement. Other than these functions,
1774 server has nothing to do with this packet.
1776 * Added support for private message key packets into the server.
1777 Added functions silc_server_private_message_key and
1778 silc_server_send_private_message_key.
1782 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1783 called in the protocol's final callback instead in the END
1784 protocol state. This makes a little more sense and in the same
1785 time in client we can use the same protocol routines for normal
1786 key exchange and to key agreement packet handling as well.
1788 * Added to both client's and server's KE protocol context the
1789 SilcSKEKeyMaterial pointer to save the key material. We will
1790 bring the key material to the protocol's final callback by doing
1791 this. The final callback must free the key material.
1793 * Added SKE's packet_send callback into client's KE protocol
1794 context so that the caller can choose what packet sending function
1795 is used. This way we can use different packet sending when
1796 doing normal SKE when doing key agreement packet handling (in
1797 the key agreement packet handling we do not want to encrypt
1800 * Implemented the responder side of the key agreement routines
1801 in the client. The client can now bind to specified port and
1802 accept incoming key negotiation. The key material is passed
1803 to the application after the protocol is over.
1805 * Implemented the processing of incoming Key Agreement packet
1806 in the client. Added function silc_client_key_agreement to
1809 * Implemented the intiator side of the key agreement routines
1810 in the client. The client can now initiate key agreement with
1811 another remote client. The key material is passed to the
1812 application after the protocol is over.
1814 * Created client_keyagr.c to include all the key agreement
1817 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1818 SILC_TASK_CALLBACK except that it is not static.
1820 * Created client_notify.c and moved the Notify packet handling
1821 from the client.[ch] into that file.
1823 * Created client_prvmsg.c and moved all private message and
1824 private message key routines from the client.[ch] into that file.
1826 * Create client_channel.c and moved all channel message and
1827 channel private key routines from the client.[ch] into that file.
1829 * Changed silc_client_get_client_by_id_resolve to resolve with
1830 WHOIS command instead of IDENTIFY command, in the file
1831 lib/silclient/idlist.c.
1833 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1835 * Implemented the SKE's responder side to the Client library.
1837 * When FAILURE is received to the protocol do not trust it
1838 blindly. Register a timeout to wait whether the remote closes
1839 the connection as it should do it, only after that process the
1840 actual failure. This was changed to both client and server.
1842 * Added client_internal.h to include some of the structures
1843 there instead of client.h in lib/silcclient/.
1845 * Added function silc_task_unregister_by_callback to unregister
1846 timeouts by the callback function.
1848 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1850 * Some "Incomplete WHOIS info" errors has been appearing on the
1851 log files. Took away the entry->userinfo check from WHOIS
1852 reply sending. The entry->userinfo is now " " if client did not
1853 provide one. I thought this was fixed earlier but something
1854 is wrong still. Let's see if the error still appears.
1856 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1858 * Fixed a minor bug in the login when the channel key is
1859 re-generated in the server. It used to generate the key in
1860 wrong order and thus caused problems in the channel traffic.
1862 * Fixed a minor bug in channel key distsribution after
1863 KICK command. The key was not sent to the router even though
1866 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1868 * Added silc_ske_process_key_material_data as generic routine
1869 to process any key material as the SILC protocol dictates. The
1870 function is used by the actual SKE library but can be used by
1871 applications as well. This relates to the private message keys
1872 and the channel private keys since they must be processed the
1873 same way the normal SILC session keys. The protocol dictates
1874 this. Affected files: lib/silcske/silcske.[ch].
1876 Added also silc_ske_free_key_material to free the
1877 SilcSKEKeyMaterial structure.
1879 * Defined silc_cipher_set_key function to set the key for
1880 cipher without using the object's method function. The affected
1881 files: lib/silccrypt/silccipher.[ch].
1883 * Implemented silc silc_client_add_private_message_key,
1884 silc_client_add_private_message_key_ske,
1885 silc_client_del_private_message_key,
1886 silc_client_list_private_message_keys and
1887 silc_client_free_private_message_keys functions in the
1890 Added functions silc_client_send_private_message_key to send
1891 the Private Message Key payload and silc_client_private_message_key
1892 to handle incoming Private Message Key payload.
1894 * Added Cipher field to the Private Message Key payload to set
1895 the cipher to be used. If ignored, the default cipher defined
1896 in the SILC protocol (aes-256-cbc) is used.
1898 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1900 * Removed lib/silcclient/ops.h file.
1902 Redefined parts of the SILC Client Library API. Created new
1903 file silcapi.h that deprecates the ops.h file and defines the
1904 published Client Library API. Defined also private message key
1905 API and channel private key API into the file.
1907 This is the file that the application must include from the
1908 SILC Client Library. Other files need not be included by
1909 the application anymore.
1911 * Added new key_agreement client operation callback and also
1912 defined the Key Agreement library API for the application.
1914 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1917 is used by clients to request key negotiation between another
1918 client in the SILC network. If the negotiation is started it
1919 is performed using the SKE protocol. The result of the
1920 negotiation, the secret key material, can be used for example
1921 as private message key.
1923 Implemented the Key Agreement payload into the files
1924 lib/silccore/silauth.[ch].
1926 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1928 * Redefined ciphers for the SILC protocol. Added some new ciphers
1929 and defined the key lengths for the algorithms. Changed the
1930 code accordingly. The default key length is now 256 bits.
1932 * Fixed SKE key distribution function silc_ske_process_key_material
1933 when the key length is more than 128 bits. The default key
1934 length in SILC is now 256 bits.
1936 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1937 to indicate unsupported algorithm.
1939 * Renamed rijndael.c to aes.c and all functions as well.
1941 * Fixed a long standing channel key setting bug in client library.
1942 Weird that it has never surfaced before.
1944 * Fixed bug in channel deletion. If the entire channel is removed
1945 then it must also delete the references of the channel entry
1946 from the client's channel list as the client's channel entry and
1947 the channel's client entry share same memory.
1949 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1951 * Implemented CONNECT and SHUTDOWN commands in the client.
1953 * Implemented CLOSE command to the client.
1955 * Added the function silc_idlist_find_server_by_name into the
1956 files silcd/idlist.[ch].
1958 Added the function silc_idlist_find_server_by_conn into the
1959 files silcd/idlist.[ch].
1961 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * DIE command was renamed to SHUTDOWN. Updated the both code
1966 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1967 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1969 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1972 * Added function silc_server_create_connection function to create
1973 connection to remote router. My server implementation actually
1974 does not allow router to connect to normal server (it expects
1975 that normal server always initiates the connection to the router)
1976 so the CONNECT command is only good for connecting to another
1979 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1981 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1982 or some other client was kicked from the channel.
1984 Implemented the handling of the notify type to both client
1987 Implemented silc_server_send_notify_kicked to send the KICKED
1988 notify. It is used to send it to the server's primary router.
1990 * Implemented the KICK command into server and client.
1992 * Added `query' argument to the silc_idlist_get_client function
1993 to indicate whether to query the client from server or not if
1996 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1997 to indicate that the client is not channel founder.
2001 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2003 * Removed the rng context from SilcPacketContext structure and
2004 changed that the packet routine uses the Global RNG API.
2006 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2008 * Added support for quit message that client can "leave" on the
2009 channel when it quits the SILC. It is ditributed inside the
2010 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2012 Added silc_server_free_client_data that will take the
2013 signoff message as argument.
2015 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2017 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2019 * Updated parts of the protocol specification to keep it up
2022 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2024 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2025 payloads in one packet.
2027 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2028 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2029 use now the new List flag.
2031 * Also deprecated the following packet types: REPLACE_ID,
2032 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2034 * Added list support for Notify packet in server.
2036 * Added silc_server_send_notify_channel_change to send the
2037 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2038 the silc_server_send_replace_id.
2040 * Added silc_server_send_notify_nick_change to send the
2041 NICK_CHANGE notify type. Deprecates the function
2042 silc_server_send_replace_id.
2044 * Added silc_server_send_notify_join to send the JOIN notify type.
2045 Deprecates the function silc_server_send_new_channel_user.
2047 * Added silc_server_send_notify_leave to send LEAVE notify type.
2048 Deprecates the function silc_server_send_remove_channel_user.
2050 * Added silc_server_send_notify_cmode and
2051 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2052 types. Deprecates the silc_server_send_set_mode function.
2054 * Added SERVER_SIGNOFF notify type to indicate that server has
2055 quit. This means that all clients on the channel from that
2056 server will drop. This can be also used when netsplit happens.
2058 Deprecated REMOVE_ID packet type since it is not needed anymore
2061 Added silc_server_send_notify_server_signoff to send the
2062 SERVER_SIGNOFF notify type. Deprecates the function
2063 silc_server_send_remove_id.
2065 Added also silc_server_send_notify_signoff to send the
2066 SIGNOFF notify type.
2068 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2069 SILC protocol from this day on. Changed the protocol
2070 specification as well.
2072 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2073 notify type. It is used between routers to notify about
2074 topic changes on a channel.
2076 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2079 * Partly updated the protocol specification to comply with the
2080 changes now made. It is still though a bit outdated.
2082 * The JOIN notify type now takes one extra argument <Channel ID>.
2083 The packet used to be destined to the channel but now the
2084 JOIN type may be sent as list thus it is impossible to
2085 destine it to any specific channel. By adding this argument
2086 it is again possible.
2088 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2090 * Added CREDITS file. The CHANGES and CREDITS file will appear
2091 in the distribution as well.
2093 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2095 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2096 types in the server's silcd/packet_receive.c.
2098 * Implemented CMODE and CUMODE to work in router environment.
2100 * Fixed minor encoding and decoding buglet from the
2101 lib/silccore/silcmode.c.
2103 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2106 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2108 * Changed all SilcConfigServer* and silc_config_server* to
2109 SilcServerConfig* and silc_server_config*, respectively.
2112 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2114 * Associated the ID (client or server ID) to the Authentication
2115 Payload to avoid any possibility of forging. Updated the
2116 protocol specification and the code accordingly.
2118 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2120 * The RSA key length is now save to the RsaKey context in the
2121 key generation process in lib/silccrypt/rsa.c. The key length
2122 is now used to figure out the maximum size of the block allowed
2123 to be encrypted/signed.
2125 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2126 is equivalent to the silc_mp_mp2bin but does not allocate any
2129 * Changed silc_mp_mp2bin API to take length argument. If it is
2130 non-zero then the buffer is allocated that large. If zero, then
2131 the size is approximated using silc_mp_sizeinbase, which however
2134 * Created Global RNG API which is global RNG that application can
2135 initialize. After initializing, any routine anywhere in the
2136 code (including library) can use RNG without allocating a new
2137 RNG object. This was done to allow this sort of use of the
2138 RNG in code that has no chance to allocate RNG object. All
2139 applications currently allocate this and many routines in the
2140 library use this. Affected file lib/silccrypt/silcrng.[ch].
2142 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2143 it to use the Global RNG API.
2145 * Defined Authentication Payload into protocol specification that
2146 is used during SILC session to authenticate entities. It is
2147 used for example by client to authenticate itself to the server
2148 to obtain server operator privileges.
2150 Implemented this payload into the lib/silccore/silcauth.[ch].
2151 Implemented also routines for public key based authentication
2152 as the new protocol specification dictates.
2154 Moved definitions of different authentication methods from
2155 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2157 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2158 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2159 silc_pkcs_verify_with_hash functions into the file
2160 lib/silccrypt/silcpkcs.[ch].
2162 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2164 * The client entry's userinfo pointer must be always valid.
2165 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2166 will fail since it requires the userinfo. Now, the userinfo
2167 is allocated as "" if actual userinfo does not exist. Actually,
2168 it must exist and it is totally Ok to drop client connections
2169 that does not announce the userinfo. However, we will make
2170 this workaround for now.
2172 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2173 to return the remote port by socket.
2175 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2177 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2178 SILC_SERVER_PENDING_EXEC and added an new macro
2179 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2180 data or when error occurs while processing the pending command.
2182 Added new argument `destructor' into silc_server_command_pending
2183 and to the SilcServerCommandPending object. This destructor is
2184 now called after calling the pending callback or if error occurs
2185 immediately. If error occurs the actual pending callback won't
2186 be called at all - only the destructor. The destructor may be
2187 NULL if destructor is not needed.
2189 All this applies for client library code as well. Similar
2190 changes were made there as well for the pending commands.
2192 In the client, the application must now allocate the
2193 SilcClientCommandContext with the silc_client_command_alloc
2196 * Added reference counter to the SilcServerCommandContext. Added
2197 function silc_server_command_alloc and silc_server_command_dup
2200 Same type of functions added to the client library for the same
2203 * Removed the cmd_ident from IDListData away since it is now
2204 global for all connections. It is the command identifier used
2205 in command sending and with pending commands. The affected file
2208 * Added reference counter to the SilcSocketConnection objecet to
2209 indicate the usage count of the object. The object won't be
2210 freed untill the reference counter hits zero. Currently only
2211 server uses this, and client ignores it. The client must be
2212 set to use this too later. The affected files are
2213 lib/silccore/silcsockconn.[ch]. Added also the function
2214 silc_socket_dup to increase the reference counter.
2216 This was mainly added because it is possible that the socket
2217 is removed underneath of pending command or other async
2218 operation. Now it won't be free'd and proper DISCONNECTING
2219 flags, etc. can be set to avoid sending data to connection that
2220 is not valid anymore.
2222 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2223 the connection. After that it sets SILC_SET_DISCONNECTED.
2224 It is, however, possible that the socket data is not still freed.
2225 The silc_server_packet_process now checks that data is not
2226 read or written to connection that is DISCONNECTED. The socket
2227 get's freed when the reference counter hits zero.
2229 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Changed the client operation API: channel_message operation's
2232 `sender' is now the client entry of the sender, not the nickname
2233 and the `channel' is the channel entry, not the channel name.
2235 In the private_message operation the `sender' is now also the
2236 client entry of the sender not the nickname.
2238 Affected file is lib/silcclient/ops.h and all applications
2239 using the client operations.
2241 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * Moved the calling of ops->connect() from connect_to_server_final
2244 into receive_new_id functin since that is the point when the
2245 client is actually allowed to send traffic to network. The
2246 affected file is lib/silcclient/client.c.
2248 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2250 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2251 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2252 (if needs broadcasting) instead of broadcasting the packets one
2253 by one which would make a burst in the network traffic.
2255 * Added `broadcast' argument to the functions in silcd/server.[ch]
2256 silc_server_create_new_channel[_with_id] to indicate whether
2257 to send New Channel packet to primary router.
2259 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Added new function into the silcd/server.[ch] files:
2262 silc_server_create_new_channel_with_id to create new channel with
2263 already existing Channel ID.
2265 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2266 lib/silccore/silcpacket.h. This packet is used t send list of
2267 Set Mode payloads inside one packet. Server uses this to set
2268 the modes for the channels and clients on those channels, that it
2269 announced to the router when it connected to it. The protocol
2270 specification has been updated accordingly.
2272 * The silc_server_new_channel did not handle the packet coming
2273 from normal server as it normally does not send that. However,
2274 when it announces its channels it does send it. Implemented
2275 the support for that.
2277 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2278 into the file lib/silccore/id.h.
2280 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * Fixed memory leaks in the functions silc_idlist_del_client,
2283 silc_idlist_del_channel and silc_idlist_del_server in the file
2284 silcd/idlist.c. All of those leaked like a sieve.
2286 * Fixed some small memory leaks in the client's function
2287 silc_client_notify_by_server.
2289 * Added functions into silcd/server.c: silc_server_announce_clients,
2290 silc_server_announce_channels and silc_server_announce_server.
2291 These functions are used by normal and router server to announce
2292 to its primary router about clients, channels and servers (when
2293 router) that we own. This is done after we've connected to the
2296 These functions effectively implements the following packet types:
2297 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2298 and SILC_PACKET_NEW_ID_LIST.
2300 * Added new functions into the silcd/packet_receive.[ch]:
2301 silc_server_new_id_list, silc_server_new_channel_list and
2302 silc_server_new_channel_user_list to handle the incoming
2303 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2305 * Added support of changing Channel ID in the function
2306 silc_server_replace_id. If the server that announces a channel
2307 to the router already exists in the router (with same name but
2308 with different Channel ID), router is responsible to send
2309 Replace ID packet to the server and force the server to change
2310 the Channel ID to the one router has.
2312 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2313 client that the Channel ID has been changed by the router. The
2314 normal server sends this to the client. Client must start using
2315 the new Channel ID as the channel's ID.
2317 Implemented handling of this new type into lib/silcclient/client.c
2318 into the function silc_client_notify_by_server.
2320 * Added new function silc_idlist_replace_channel_id into the files
2321 silcd/idlist.[ch] to replace the Channel ID.
2323 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2325 * Call silc_server_command_identify_check always when processing
2326 the IDENTIFY command in silcd/command.c
2328 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2330 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2331 send keepalive packets. The packet can be sent by clients,
2332 servers and routers.
2334 Added function silc_socket_set_heartbeat into the file
2335 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2336 If not set, the heartbeat is not performed. The actual
2337 heartbeat is implemented in the low level socket connection
2338 library. However, application is responsible of actually
2341 Added silc_server_send_heartbeat to send the actual heartbeat
2342 packet into silcd/packet_send.[ch]. Server now performs
2343 keepalive with all connections.
2345 * Added silc_task_get_first function into lib/silcutil/silctask.c
2346 to return the timeout task with shortest timeout. There was a bug
2347 in task unregistration that caused problems. TODO has been
2348 updated to include that task system must be rewritten.
2350 * The client library will now resolve the client information when
2351 receiving JOIN notify from server for client that we know but
2352 have incomplete information.
2354 * Rewrote parts of silc_server_remove_from_channels and
2355 silc_server_remove_from_one_channel as they did not remove the
2356 channel in some circumstances even though they should've.
2358 * Encryption problem encountered in server:
2360 The LEAVE command used to send the Channel Key packet to the
2361 router immediately after generating it. However, the code
2362 had earlier sent Remove Channel user packet but not immediately,
2363 ie. it was put to queue. The order of packets in the router
2364 was that Channel Key packet was first and Remove Channel User
2365 packet was second, even though they were encrypted in the
2366 reverse order. For this reason, MAC check failed. Now, this
2367 is fixed by not sending the Channel Key packet immediately but
2368 putting it to queue. However, this is more fundamental problem:
2369 packets that are in queue should actually not be encrypted
2370 because packets that are sent immediately gets encrypted
2371 actually with wrong IV (and thus MAC check fails). So, packets
2372 that are in queue should be encrypted when they are sent to
2373 the wire and not when they put to the queue.
2375 However, the problem is that the current system has not been
2376 designed to work that way. Instead, the packet is encrypted
2377 as soon as possible and left to the queue. The queue is then
2378 just purged into wire. There won't be any fixes for this
2379 any time soon. So, the current semantic for packet sending
2382 o If you send packet to remote host and do not force the send
2383 (the packet will be in queue) then all subsequent packets to the
2384 same remote host must also be put to the queue. Only after the
2385 queue has been purged is it safe again to force the packet
2388 o If you send all packets immediately then it safe to send
2389 any of subsequent packets through the queue, however, after
2390 the first packet is put to queue then any subsequent packets
2391 must also be put to the queue.
2393 Follow these rules and everything works fine.
2395 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2397 * Added new function silc_server_remove_clients_by_server to
2398 remove all client entries from ID list when the server connection
2399 is lost. In this case it is also important to invalidate all
2400 client entires as they hold the invalid server entry. This
2401 fixes fatal bug when server has lost connection and will reconnect
2404 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2406 * Made some sanity checks to silc_server_daemonise like to check
2407 whether the requested user and group actually exists.
2409 * Added sanity check to SKE's silc_ske_responder_finish to check
2410 that the public and private key actually is valid.
2412 * Invalidate the client's nickname when receiving Replace ID
2413 packet and the Client ID is being replaced. This means that the
2414 server will query the nickname if someone needs it (client)
2417 * Sort the ID Cache in client library when the ID Cache data
2418 has changed (needs sorting).
2420 * Do not allow for SILC client to create several connections to
2421 several servers. The client does not support windows right now
2422 and generating multiple connections causes weird behaviour.
2424 Irssi-silc client does support windows and can handle several
2425 connections without problems, see: www.irssi.org and SILC plugin.
2427 * Fixed some places where client was added to the IDList. The
2428 rule of thumb is following (in order to get everything right):
2429 If the client is directly connected local client then the
2430 `connection' argument must be set and `router' argument must be
2431 NULL to silc_idlist_add_client function. If the client is not
2432 directly connected client then the `router' argument must
2433 bet set and the `connection' argument must be NULL to the
2434 silc_idlist_add_client function.
2436 * The funtion silc_server_packet_send_local_channel actually did
2437 not check whether the client was locally connected or not. It
2438 does that now. Fixed a bug related to LEAVE command.
2440 * Fixed Remove Channel User payload parsing bug in server's
2441 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2443 * The server's silc_server_save_channel_key now checks also the
2444 global ID list for the channel as it might not be in the local
2445 list. Fixed a bug related to LEAVE command.
2447 * Is this the end of the [<unknown>] buglet that has been lurking
2448 around for a long time? A little for loop fix in server's
2449 silc_server_command_whois_parse that is used by both IDENTIFY
2450 and WHOIS command. At least, this was a clear bug and a cause
2451 of one type of [<unknown>] buglet.
2453 * WHOIS and IDENTIFY commands call the function
2454 silc_server_command_[whois/identify]_check function even if
2455 we are not router server.
2457 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2459 * Added --with-gmp configuration option. If set the GMP
2460 is always compiled in the SILC source tree. If not set then
2461 it is checked whether the system has the GMP3 installed. If
2462 it has then the GMP won't be compiled (the system's headers
2463 and library is used), if it doesn't have it then the GMP is
2464 compiled in the SILC source tree.
2466 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Changed RSA private exponent generation to what PKCS #1
2469 suggests. We try to find the smallest possible d by doing
2470 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2471 not security fix but optimization.
2473 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2475 * Added new config entry [Identity] to fork the server and run
2476 it as specific user and group. A patch from Bostik.
2478 * Imported Dotconf configuration library into lib/dotconf.
2479 This will be used to create the SILC configuration files later.
2480 It will appear in the distsribution after this commit.
2482 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2484 * A big code auditing weekend happening. Auditing code for
2485 obvious mistakes, bugs and errors. Also, removing any code
2488 Removed files for being obsolete:
2490 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2491 inline in the file lib/silcutil/silcbuffer.h)
2493 o lib/silcutil/silcbufutil.c (the header has inline versions)
2495 Changed code to fix possible error conditions:
2497 o The buffer formatting routines now check that the destination
2498 buffer really has enough space to add the data. This applies for
2499 both buffer formatting and unformatting
2500 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2501 unformatting was changed to accomodate following rules:
2502 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2503 sent to the function while XXX_*STRING will not allocate or copy
2504 the data into the buffer. Instead it sets the pointer from the
2505 buffer into the pointer sent as argument (XXX_*STRING used to
2506 require that the pointer must be allocated already). This change
2507 makes this whole thing a bit more consistent and more optimized
2508 (note that the data returned in the unformatting with XXX_*STRING
2509 must not be freed now). The routines return now -1 on error.
2511 o Tried to find all code that use buffer_format and buffer_unformat
2512 and added return value checking to prevent formatting and
2513 especially unformatting errors and possible subsequent fatal
2516 o Changed ske->x and ske->KEY to mallocated pointers in
2517 lib/silcske/silcske.h. Fixed possible data and memory leak.
2519 o Added return value checking to all *_parse* functions. Fixed
2520 many memory leaks as well.
2522 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2523 so that buffer overflows would not happen. All code now also
2524 checks the return value as it can fail.
2526 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2528 * Added reconnection support to server if the normal server looses
2529 its connection to the router (for example if router is rebooted).
2530 The server performs normal reconnection strategy implemented
2531 to the server. Affected file silcd/server.c.
2533 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2535 * Added new packet type SILC_PACKET_SET_MODE that is used to
2536 distribute the information about changed modes (for clients,
2537 channels and clients channel modes) to all routers in the
2538 network. Updated the protocol specification accordingly.
2540 Added functions into silcd/packet_send.c and
2541 silcd/packet_receive.c: silc_server_send_set_mode,
2542 silc_server_set_mode.
2544 Added new files silcmode.[ch] into lib/silccore that implements
2545 the encoding and decoding of Set Mode Payload. Added new type
2546 SilcSetModePayload. Moved the definitions of different modes
2547 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2549 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * Oops, a little mistake in server's connection authentication
2552 protocol. The protocol is not ended with FAILURE but with
2553 SUCCESS if the authentication is Ok. :) Affected file is
2556 * Implemented NICK_CHANGE notify handling in server in the file
2557 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2558 the local clients on the channel. After the changing nickname
2559 in router environment snhould work and the [<unknown>] nickname
2560 should appear no more.
2562 The silc_server_replace_id function that receives the Replace ID
2563 payload now sends the NICK_CHANGE notify type also in the file
2564 silcd/packet_receive.c
2566 * Changed WHOIS and IDENTIFY command to support the maximum amount
2567 of arguments defined in protocol specs (3328 arguments). This
2568 fixed a bug that caused problems when there were more than three
2571 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2573 * Added extra parameter, command identifier, to the
2574 silc_client_send_command so that explicit command identifier
2577 Changed that ID list routines uses specific command identifier
2578 when sending WHOIS/IDENTIFY requests to the server so that they
2579 can be identified when the reply comes back.
2581 Affected files lib/silcclient/command.[ch],
2582 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2584 * Added `sender' argument to silc_server_packet_send_to_channel
2585 to indicaet the sender who originally sent the packet to us
2586 that we are now re-sending. Ignored if NULL. Affected file
2587 silcd/packet_send.[ch].
2589 * Added some server statistics support in silcd/server_internal.h
2590 SilcServerStatistics structure and around the server code. Also
2591 send some nice statistics information when client is connecting
2594 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Fixed channel ID decoding in server's JOIN command reply in
2597 silcd/command_reply.c
2599 * Fixed braodcasting of replace ID payload to not to send it if
2600 we are standalone server in silcd/packet_receive.c.
2602 * Fixed all channel message sending routines to not to send
2603 packets to clients that has router set, since they are routed
2604 separately in the same function earlier. Affects file
2605 silcd/packet_send.c and all channel packet sending functions.
2607 * In USERS reply, res_argv[i] are not allocated, the table
2608 is allocated. Thus changed that free the table, not its
2611 * In server's whois_check and identify_check if the client is
2612 locally connected do not send any WHOIS commands - they are not
2615 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * Fixed some minor bugs in client when sending WHOIS command. The
2618 arguments was in wrong order.
2620 * Removed statis function add_to_channel from server in
2621 silcd/command.c that was previously used with the joining but
2624 * Tested USERS command in router environment successfully with two
2625 routers, two servers and two clients.
2627 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Reorganized the USERS command and command reply in client library
2630 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2631 When the command is given by user we register a pending command
2632 callback that will reprocess the command after the reply has been
2633 received from the server. When reprocessing the packet we then
2634 display the information. Thus, the USERS information is displayed
2635 now in the command callback instead of in the command reply
2636 callback. The processing of the command is same as previously
2637 when server has sent the command reply in the JOINing process.
2639 * Added to USERS command in silcd/command_reply.c to join the client,
2640 we didn't use to know about, to the channel after we've created
2641 a client entry for it. Also, for clienet we did know already still
2642 check whether it is on the channel or not and add it if not.
2644 * Removed silc_server_command_join_notify as the function and its
2647 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2649 * Changed the client's pending command handling to the same as the
2650 server's pending command handling. It is also now possible to
2651 execute command reply functions from other command reply
2652 function as the function callbacks for commands and command
2653 replies are one and same. The pending commands are not static
2654 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2655 in client connection context. Thus, pending commands are server
2656 connection specific as it is convenient.
2658 Changed the function silc_client_command_pending and
2659 silc_client_command_pending_del and added new function
2660 silc_client_command_pending_check. Removed the
2661 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2664 * Added cmd_ident, current command identifier, to the client
2665 connection context in lib/silcclient/client.h to keep track on
2666 command identifiers used in command sending. Client's command reply
2667 function handling now supports the mandatory command identifiers.
2669 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2670 funtions in client to fully support pending command callbacks.
2672 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2673 as one of the arguments to the application in the command reply
2676 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2677 before first releasing SILC but came back. Now it is removed again
2678 and should come back nomore. The FORWARDED flag was used only
2679 by the JOINing procedure by forwarding the command packet to router.
2680 Now, the JOINing procedure has been changed to more generic (due
2681 to various router environment issues) and FORWARDED is not needed
2682 anymore for anything. The protocol specification is yet to be
2685 Now, removed silc_server_packet_forward from server and the flag
2686 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2688 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2690 * Renamed NAMES command to USERS command. The NAMES was named that
2691 due to historical reasons. Now it is renamed. Also, rewrote
2692 parts of the USERS command. The nickname list is not sent anymore
2693 by the server. Only Client ID and mode lists are sent in the USERS
2694 command. Changed this also to the protocol specification.
2696 The client now resolves the names and stuff after it receives
2697 the USERS list from the server when joining to the channel.
2699 * WHOIS and IDENTIFY commands has been changed to support multiple
2700 Client ID's per command. One can now search for multiple users
2701 in the network by sending only one WHOIS or IDENTIFY command.
2702 Changed the code and the protocol specifications.
2704 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2705 uses silc_server_command_whois_parse to parse the request. */
2707 * If normal server, do not parse the WHOIS and IDENTIFY requests
2708 before sending it to the router. Saves some time.
2710 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2712 * Fixed JOIN command on client library. Wrong number of arguments
2713 used to crash the client.
2715 * Added silc_server_channel_has_global function to check whether
2716 channel has global users or not.
2718 * Added silc_server_channel_has_local function to check whether channel
2719 has locally connected clients on the channel.
2721 * The silc_server_remove_from_one_channel now checks whether the
2722 channel has global users or not after given client was removed from
2723 the channel. It also checks whether the channel has local clients
2724 on the channel anymore. If it does not have then the channel entry
2725 is removed as it is not needed anymore.
2727 * The silc_server_notify now checks on JOIN notify whether the joining
2728 client is one of locally connected or global. If it is global then
2729 the channel has now global users on the channel and that is marked
2730 to the channel entry. Also, it now saves the global client to
2731 global list who is joining and JOINs it to the channel. This is
2732 for normal server, that is.
2734 Changed silc_server_send_notify_on_channel,
2735 silc_server_packet_relay_to_channel and
2736 silc_server_packet_send_to_channel check if we are normal server
2737 and client has router set (ie. global client) do not send the
2738 message to that client, as it is already routed to our router.
2740 * Implemented LEAVE notify type handling in silc_server_notify
2743 * Tested LEAVE command in router environment successfully. Tested
2744 with two routers, two servers and two clients.
2748 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2750 * Implemented SIGNOFF notify type handling in silc_server_notify
2753 * silc_server_remove_id now removes the client entry from all channels
2754 it has joined and thusly sends SIGNOFF notify type.
2756 * Rewrote the NAMES list generation in server by removing two excess
2757 loops. The lists are created now inside one loop.
2759 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2761 * silc_server_remove_channel_user checks now also global list
2762 for channel and client.
2764 * silc_server_new_channel_user checks now both local and global
2765 list for channel and client. Fixed a bug in client id decoding.
2766 Used to decode wrong buffer.
2768 * silc_server_channel_message checks now both local and global
2769 list for channel entry.
2771 * Tested channel joining (hence JOIN) in router environment
2772 successfully. Tested with two routers, two servers and two
2775 * Tested channel message sending in router environment successfully.
2777 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2779 * Added silc_server_save_channel_key into server.[ch] to save the
2780 received channel key in Channel Key payload processing. It is
2781 also used in JOIN command reply handling.
2783 Equivalent function silc_client_save_channel_key added into
2784 client.[ch] into client library.
2786 * Changed JOIN command reply to send information whether the channel
2787 was created or not (is existing already) and the channel key
2788 payload. Changed protocol specs accordingly.
2790 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2791 the request was sent by ID and not by nickname. Crashed on
2794 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2796 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2797 now correctly save the received data.
2799 * silc_server_free_sock_user_data now notifies routers in the
2800 network about entities leaving the network.
2802 At the same time implemented functions silc_server_remove_id
2803 and silc_server_send_remove_id to receive and send REMOVE_ID
2804 packets. The packet is used to notify routers in the network
2805 about leaving entities. The ID removed will become invalid in
2808 * Added function silc_idlist_del_server into server. Removes and
2809 free's server entry from ID list.
2811 * silc_server_private_message function now checks, if we are router,
2812 that the destination ID really is valid ID, naturally.
2814 * In router when NEW_ID packet is received (for new client) the
2815 hash of the Client ID is saved in the ID Cache but the
2816 client->nickname is set to NULL, instead of putting the hash
2819 IDENTIFY command now also checks that client->nickname must be
2820 valid. If it is not if will request the data from the server who
2821 owns the client. Added new function
2822 silc_server_command_identify_check.
2824 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2825 to set the command to already allocated Command Payload.
2827 * Tested private message sending in router environment with two
2828 routers, two servers and two clients. Fixed minor bugs and now
2831 * Fixed segfault from client's NAMES command. Used to crash if
2834 * Forwarded packets must not be routed even if it is not destined
2835 to the receiver. Changed server code comply with this.
2837 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2839 * Added `require_reverse_mapping' boolean value to ServerParams
2840 structure. If TRUE (not default) the server will require that
2841 the connecting host has fully qualified domain name.
2843 If the reverse mapping is not required and hostname could not be
2844 found the IP address is used as hostname.
2846 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2848 * Implemented version string checking to both client and server.
2849 The check is incomplete currently due to the abnormal version
2850 strings used in development version of SILC.
2852 * Changed all command functions in server to use the new
2855 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2857 * Changed char *data to unsigned char *data in ID Cache system to
2858 support binary data as ID Cache data. Changed code to support
2859 binary data in lib/silccore/idcache.c.
2861 * Renamed silc_server_packet_relay_command_reply to
2862 silc_server_command_reply as it is normal packet receiving
2863 function. Rewrote the function to accept command replys for
2864 servers and not only for clients.
2866 * Mark remote router always as registered server if we are connecting
2867 to it. Otherwise, commands sent by the router to us are ignored.
2869 * All ID List find routines now returns the ID Cache Entry pointer
2870 as well if requested.
2872 * WHOIS command works now in router environment, tested with two
2873 routers, two servers and two clients.
2875 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2876 in router environment (as it is almost equivalent to WHOIS) but
2877 hasn't been tested thoroughly. Added new functions:
2879 silc_server_command_identify_parse
2880 silc_server_command_identify_send_reply
2881 silc_server_command_identify_from_client
2882 silc_server_command_identify_from_server
2884 * Disabled route cache adding because adding two different ID's with
2885 same IP replaces the old cache entry thus giving wrong route.
2886 The entry->router->connection is always the fastest route anyway
2887 so route cache may not be needed. Of course, new routes maybe
2888 established after receiving the ID when the entry->router->connection
2889 might not be anymore the most optimal.
2891 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Add route cache for received ID for fast routing.
2895 * Added silc_server_packet_route to route received packet on router
2896 that is not destined to us.
2898 * Renamed silc_server_get_route to silc_server_route_get.
2900 * Added id_string and id_string_len fields into SilcServer to
2901 include encoded ServerID for fast comparing without excess
2902 encoding of the ID's.
2904 * Cleaned up WHOIS command on server side. Added following static
2907 silc_server_command_whois_parse
2908 silc_server_command_whois_check
2909 silc_server_command_whois_send_reply
2910 silc_server_command_whois_from_client
2911 silc_server_command_whois_from_server
2913 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2914 arguments in command replies. All command functions should be
2915 updated to use this macro.
2917 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Minor typo fixes on command reply handling on server.
2921 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2923 * Added silc_server_command_add_to_channel internal routine to add
2924 the client to the channel after router has created the channel and
2925 sent command reply to the server.
2927 * Added generic silc_server_send_command to send any command from
2930 * Use static buffer with ID rendering instead of duplicating data.
2932 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2934 * Fixed a channel user mode bug when joining to a channel server gave
2935 everybody channel founder rights, oops.
2937 * We mark ourselves as the router of the incoming server connection
2938 if we are router ourselves. This way we can check in some packet
2939 sending functions whether it is locally connected server. For
2940 incoming router connections we put NULL.
2942 * For router sending packets locally means now always sending the
2943 packet cell wide; to local clients and local servers. For normal
2944 server sending packet locally means sending it to only local
2947 * Fixed the JOIN command to really work in router environment. If the
2948 channel is created it is always created by the router. Router is
2949 also responsible of making the initial joining to the channel,
2950 sending JOIN notify to the sending server and distributing
2951 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2952 does not exist server doesn't do anything else but forward the
2953 command to the router which performs everything.
2955 * Added silc_server_send_channel_key function to send the Channel Key
2958 * Added silc_server_create_channel_key to create new channel key. The
2959 channel key is now re-generated everytime someone joins or leaves
2960 a channel, as protocol dictates. Note: channel->key_len is the
2963 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2966 packet_receive.[ch] to separate packet sending and receiving
2967 routines. The server.[ch] now includes everything else including
2968 actual packet processing (writing and reading data) and other
2971 Renamed silc_server_private_message_send_internal to
2972 silc_server_send_private_message. The routine is still though
2973 used only to relay private messages as server does not send
2974 private messages itself.
2976 Renamed silc_server_new_channel to silc_server_create_new_channel
2977 and added new function sicl_server_new_channel that handles the
2978 incoming New Channel packet. Added also new sending function
2979 silc_server_send_new_channel to send New Channel Payload.
2981 * Added new function silc_server_notify to process incoming notify
2982 packet to the server/router. Server may then relay the notify
2983 to clients if needed.
2985 * Added new function silc_server_new_channel_user to process incoming
2986 New Channel User packet. Router will redistribute the packet and
2987 send JOIN notify to its local clients and locally connected servers
2988 if needed. Normal server will send JOIN notify to its local client
2989 on same channel when received this packet. Added also corresponding
2990 sending function silc_server_send_new_channel_user to sent the
2993 * Added boolean route argument to send_notif_to_channel and
2994 packet_send_to_channel functions to attempt to route the packet
2995 if it is TRUE and send only locally if it is FALSE.
2997 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * silc_server_replace_id now broadcasts the received replace ID
3000 packet if it is not broadcast packet already. The router must
3001 broadcast to inform other routers about changed ID.
3003 * Added backpointer to server's router into SilcServer context in
3004 silcd/server_internal.h.
3006 * Fixed silc_server_packet_broadcast to send correct broadcast
3009 * The channel key is now distributed to the local client as soon
3010 as it is received from the router (in router environment) so that
3011 no other packet may be sent for the channel until client has
3014 * silc_server_remove_channel_user now broadcasts the received
3015 Remove Channel User packet if it is not broadcast packet already.
3016 The router must broadcast to inform other routers about removed
3019 * Added users field into SilcPacketContext that is a reference count
3020 of the context. One can increase the reference count by calling
3021 silc_packet_context_dup which is now changed to just increase the
3022 reference count instead of duplicating the data. The reference
3023 count is decresed by calling silc_packet_context_free that will
3024 free the data after the reference count hits zero.
3026 For now on the packet context and everything allocated into it
3027 (including the raw packet from network) must be freed by calling
3028 the new silc_packet_context_free function. Added also new function
3029 silc_packet_context_alloc that must be used now to allocate the
3030 context. This also means that if a routine is asynchronous from
3031 silc_[client/server]_packet_parse_type the packet context must
3032 be duplicated by calling silc_packet_context_dup. Otherwise it
3033 gets free'd after silc_[client/server]_packet_parse_type returns.
3034 Also, one must remember that if packet is duplicated then its
3035 reference count must be decresed by calling the free function as
3036 many times as it was duplicated.
3038 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3039 from both client and server.
3041 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3043 * Made joining to a channel working in router environment.
3045 * Cleaned up JOIN command on server side and create function
3046 silc_server_command_join_channel internal routine to make the
3049 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * Changed silc_command_pending list to SilcDList. Also, added
3052 `ident' field to SilcServerCommandPending structure to identify
3053 the reply and to call correct callback.
3055 Added silc_server_command_pending_check function to replace the
3056 corresnponding macro. The silc_command_pending list is not
3059 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3060 to set identifier to previously allocated Command Payload. It
3061 is used to set identifier for command when resending Command
3064 * Added silc_command_payload_encode_payload to encode Command
3065 Payload buffer from SilcCommandPayload structure.
3067 * Added silc_argument_payload_encode_payload to encode Argument
3068 payload buffer from SilcArgumentPayload structure.
3070 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3072 * Changed WHOIS command to support router connection on server side.
3073 The whois request is always sent to router unless the server is
3074 standalone server. After server has received the reply from the
3075 router will it send the reply to the client.
3077 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3078 broadcast received broadcast packet. The function is used only
3079 by router. The broadcast packet is always sent to the router's
3082 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3083 render given ID to printable string, for log files for example.
3085 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * Made basic router to router connections working. At least they
3088 can now connect to each other but nothing really works the way
3089 they are supposed - yet.
3091 * Added new initiator token to RouterConnection configuration
3092 file in silcd/serverconfig.[ch]. It is used to tell whether we
3093 are the initiator to the remote router or whether we'll expect
3094 the other end to connect.
3096 * Moved registering of listener task to silc_server_init, hence
3097 the server starts listenning as soon as it is run, even if it
3098 does not have connections to other routers. Let's see how well
3101 * Changed default connection retry timeouts for more suitable in
3104 * Removed cipher and such arguments from silc_idlist_add_client
3105 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3106 Added new function silc_idlist_add_data to add the keys and stuff
3109 * Added SilcIDListData structure and added it to SilcClientEntry
3110 and SilcServerEntry as their first field in the structure. This
3111 way we can explicitly cast the ID entries to the SilcIDListData
3112 structure and get common data for the entries. In past, we had
3113 to first check what type of connection it is and then cast it to
3114 correct ID entry type. Now, we can directly cast the opaque
3115 pointer to the SilcIDListData (no matter what ID entry it actually
3116 is) and get the data needed.
3118 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3121 in some circumstances even if threre were timeout tasks, though not
3122 IO tasks, but tasks anyway. Now fixed.
3124 * Defined SilcServerConnection structure to hold connection specific
3125 stuff about directly connected servers and routers. The definition
3126 is currently in silcd/server_internal.h. I thought about having
3127 a bit more important role fro this struct but for now it is used
3128 only when connecting to other server (or router actually).
3130 * Added connecting retry support in server when connecting to
3131 router(s). The retry feature implement exponential backoff
3132 algorithm. Also, added SilcServerParams structure to hold default
3133 parameters for server. For now, it include these retry settings
3134 and are hard coded. After server is moded to be as Silc Server
3135 Library this structure will be more important.
3137 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Changed client librarys channel->clients table to SilcList and
3140 changed code accordingly.
3142 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Changed client's channel table to SilcList and changed code
3145 accordingly. Also changed SilcChannelClientEntry to include back-
3146 pointer to the channel so that client entry can use that structure
3147 as list as well and we have fast cross-reference to the channel.
3148 This change dramatically decreased the complexity of channel
3149 handling with client entry and vice versa (removed one extra
3150 loop when searching for channel entry from many functions).
3152 * Changed server->sim from table to SilcDList and changed code
3155 * NAMES command can now be used from user interface. It will show
3156 the user list on the channel, neatly.
3158 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3159 Code now saves realname of the user if it becomes available.
3161 * Renamed configure.in to configure.in.pre and made ./prepare
3162 script to automatically add correct version string to
3163 configure.in which it creates from configure.in.pre.
3165 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3167 * NAMES command reply now shows users mode with the nickname when
3170 * Moved silc_client_ch[u]mode[_char] functions from
3171 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3172 place sucks, they are utility functions and should be in some
3175 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3177 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3180 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3184 * Added TRQ (efficient deque and list library) into lib/trq. This is
3185 a very good list library that is currently used in the SILC. Defined
3186 SilcList API over the library because I didn't like the API very
3187 much. See lib/trq/silclist.h for the API and examples of how to
3188 use the API. Fixed various places in the code to use the new
3189 SilcList API. The SilcList is meant for lists that has a structure
3190 already defined as a list. It is not suitable to add just some
3191 context to the list (in TRQ, the context is the list actually).
3193 So, I defined SilcDList that can be used for the purpose where
3194 predefined list structure does not exit. This can be used as
3195 such list. Now some context just can be added to the SilcDList.
3196 Currently this list is not used in the SILC just yet, though there
3197 are a lot places where this can replace dynamically allocated
3198 tables and I will fix these places, later, to use SilcDList.
3199 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3200 and use TRQ internally).
3202 Also fixed some annoying warning messages that the original TRQ
3203 code generated. Also minor changes to TRQ's Makefile.in.
3205 * Added support for querying by Client ID to both WHOIS and
3206 IDENTIFY commands into server, as required by the protocol.
3208 * Removed method function pointers from SilcBuffer structure. They
3209 weren't used to anything and just increased the context size for
3210 no good reason. This change also made silc_buffer_alloc and
3211 silc_buffer_free functions inline functions.
3213 * Disabled command flooding detection support until it's fixed so
3214 that it accepts commands in but does not execute them more than once
3217 * Added silc_net_localhost(), to return local hostname, into
3218 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3219 that must be initialized before calling silc_client_init.
3221 * Added new function: silc_server_send_notify_on_channels to send
3222 notify messages to all channels client has joined. It is assured
3223 that the message is sent only once per client.
3225 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3226 lib/silcutil/silcutil.[ch] as silc_format function. The new
3227 function is generic and is used by server as well, not only by
3228 the logging routines.
3230 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3231 the provided version string was not acceptable. Added new function:
3232 silc_ske_check_version into lib/silcske/silcske.h. The function
3233 must be implemented by the application (client or server) and it
3234 does not reside in the SKE library. The function checks the version
3235 string remote end sent.
3237 * Added back pointers (to opaque context and to SilcSocketConnection)
3238 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3240 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3241 duplicate packet context structure.
3243 * Changed `notify' client operation to send same arguments as client
3244 receives from server except for ID's. ID's are mapped to correct
3245 ID entry and that is returned. Also, if channel entry is not sent
3246 by server but the notify is for channel the channel entry is sent
3247 to application (otherwise application doesn't know that it is for
3248 channel (library gets it from packet's Destination ID)).
3250 * Added silc_client_remove_from_channels into client library to
3251 remove a client from all channels it has joined to. Used when
3252 received SIGNOFF notify from server. Added also new function
3253 silc_client_replace_from_channels to replace old ID entry with
3254 new ID entry on all channels. Used when received NICK_CHANGE
3257 * Fixed ID Cache list handling in silc_idlist_get_client in
3258 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3259 to get (or query) client by ID.
3261 * Updated TODO list.
3263 * Added connection authentication status message defined by the
3264 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3265 support for these into the code in client and server side.
3267 * Added generic function silc_client_send_command to send any command
3268 with variable argument list. Application should use this function
3269 to send commands if the command functions provided by the library
3270 does not suite for the application's user interface needs.
3272 * Added new `failure' client operation. Application is notified about
3273 received failure packet if client is executing a protocol. In this
3274 case the protocol's execution has failed.
3276 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3277 is required by the protocol.
3279 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3280 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3283 * Added status flag to SilcSKE object to indicate realtime status
3284 of the SKE protocol.
3286 * Application receives now exactly same command reply arguments as
3287 the library receives from server. However, if ID is received the
3288 corresponding ID entry is returned to the application (eg. Client
3289 ID is mapped to correct SilcClientEntry entry and that is returned).
3290 Changed command_reply client operation due to this change.
3292 * Changed all ID's in commands and in command replys as ID Payloads.
3293 Change affected both client and server side codes.
3295 All ID's sent in SILC network (with execption of ID's in SILC
3296 Packet header) are sent in ID Payload to support variable length
3299 * Server now notifies nick changes and notifies all clients on
3300 the channels about the new nickname (about the new Client ID,
3303 * Implemented CMODE command to change channel modes. Supports all
3304 channel modes defined by the protocol specs except ban and invite
3305 lists. (Also, private channel key mode is supported but support for
3306 setting private channel key in client is missing, thus, this mode
3307 has no effect on client side (except that server requires that the
3308 client uses private channel key and normal channel traffic does not
3311 Also, invite mode works per se, but INVITE command does not work
3312 yet correctly, so you can set channel as invite only channel but
3313 inviting clients to the channel does not work (it is yet to be
3314 thought what's the best way to do it).
3316 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3317 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3318 Implemented CUMODE command to change user's mode on the channel.
3319 Supports all modes defined by the protocol specs.
3321 * Added NAMES command reply to return users modes on the channel.
3323 * Removed unnecessary and slow ciphers from lib/silccrypt.
3325 * Set SO_KEEPALIVE option to connection sockets by default.
3327 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3329 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3330 redefined the Notify Payload into protocol specs.
3332 * Added silc_id_payload_parse_id to get ID directly from raw
3335 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3338 accept searching by Client ID as well.
3340 * Added support for LEAVE and SIGNOFF notify types in client library.
3342 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3343 to parse ID Payload from raw data.
3345 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Added flags parameter into silc_ske_assemble_security_properties
3348 function in lib/silcske/silcske.[ch].
3350 * Changed notify client operation to fit better for notify messages
3351 sent by server. The notify payload received from server is now
3352 passed to the application (after parsing it to SilcNotifyPayload).
3353 It is application's responsibility to retrieve the arguments
3354 from the payload and show the message the way it wants. The message
3355 sent by server is implementation specific.
3357 * Changed public keys to comply with the protocol specification.
3358 Old public keys are not supported anymore and are not compatible.
3360 * Removed nickname from Channel Payload as the latest draft removed
3361 it. The client must resolve the nickname from the NAMES command
3362 reply received when it joined the channel.
3364 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3366 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3368 * Fixed some errors in protocol specification drafts.
3370 * Created lib/silccore/silcnotify.c to implement Notify Payload
3371 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3372 generic payloads described by protocol specifications. The file
3373 includes implementations for ID Payload and Argument Payload.
3375 * Changed Command Payload implementation to use the new Argument
3376 Payload. Changed command_xxxx_payload to command_payload_xxxx
3377 to comply with SILC coding conventions.
3379 * Added suppport for Argument Payload handling in Notify Payload
3380 implementation as protocol requires it. Added the new support
3381 into server and client lib as well.
3383 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * Added support for multiple nicknames on same channel. [n] is
3386 added locally to the nickname if there are more than one same
3387 nicknames on the channel.
3389 * Server now sends all nicknames that matched WHOIS request.
3390 Client also shows the list received from server.
3392 * Added TOPIC command to client side. User can now set and show
3393 current topic on channel.
3395 * Added MOTD command to client and server. Also, server sends the
3396 motd when client connects to the server.
3398 * Changed version strings to comply ISO 8601.
3400 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Fixed protocol error handling in client library. It should now
3403 cope even if the SKE fails for some reason.
3405 * Made new protocol specification drafts for submitting to IETF.
3407 * Implemented TOPIC command to server in silcd/command.c.
3409 * Added two new notify types into lib/silccore/silcnotify.h:
3410 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3411 notify nickname change and topic setting/change on a channel.
3413 * API change of command_reply operation in client library. The
3414 application gets now the status type received from server as well.
3416 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3418 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3420 * Cras fixed and optimized the packet handling even further and
3421 it should work now. Minor change to the prototype of function
3422 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3424 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Added new function into lib/silcutil/silcschedule.[ch]:
3427 silc_schedule_with_fd to select() a specified fd. The function
3428 returns after timeout expires or data arrives or goes. The
3429 function is used by packet routines to wait that all data is
3430 received from network.
3432 * Fixed data reading from network in lib/silccore/silcpacket.c.
3433 The code now assures that all data is read from the fd and then
3434 continues packet processing. This was a bug fix since the code
3435 used to drop some data in some circumstances.
3437 * Added new function into lib/silcclient/client.[ch]:
3438 silc_client_start_key_exchange to start key exchange after
3439 connection has been established to server. The code internally
3440 now uses this funtion but its main purpose was to provide it
3441 for applications that perform their own connecting. After
3442 application has created a connection it merely calls this
3443 function to start the key exchange between client and server.
3444 The library takes care of everything else after that.
3446 Updated also lib/silcclient/README to explain the usage of
3449 * Do not send to application information that connection has
3450 been established. Application gets notified it by connect
3453 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3455 * Applied cras's patch to add silc_schedule_one function. The
3456 function runs scheduler once and returns.
3458 * Fixed the scheduler after cras messed it up. The timeout
3459 handling works now as it's supposed to work.
3461 * Added into lib/silccore/ silcnotify.h to include notify
3462 message types support. Changed silc_server_send_notify*
3463 functions, in server.[ch], to support those new notify types.
3464 Added the support for the notify types into client library,
3465 as well. Added new notify client operation into ops.h in
3468 * Changed silc_server_packet_send_to_channel to send normal
3469 packets instead of just channel message packets. The function
3470 is now used to send the notify packets to channels. It is not
3471 used to send channel message packets anymore, as server never
3474 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3475 va_arg()s as it seems to require it nowadays. I guess, if SILC
3476 is compiled with older va_arg() the new code should work anyway.
3478 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Splitted core library. Core library (lib/silccore) includes
3481 now only SILC protocol specific core (and common) components.
3482 Created new utility library (lib/silcutil) that includes more
3483 generic purpose stuff. The stuff for util library was taken
3484 from the old core library. This was minor and easy split.
3486 * Created SILC Client Library (lib/silcclient) that includes
3487 implementation of the SILC client without user interface. This
3488 was major move from silc/ directory. The code has been changed
3489 so that it is transparent towards the user interface. The
3490 silc/ directory includes now the same user interface as before
3491 and it uses the new client library. Read lib/silcclient/README.
3492 Basicly, the client library performs everything else related
3493 to SILC except user interface handling. Also, configuration
3494 files are considered to be part of user interface and library
3495 does not handle them.
3497 This change also changed a lot of structures, function naming etc.
3498 Most important change was that SilcClientWindow object was
3499 renamed to SilcClientConnection in the client library. Created
3500 also new file lib/silcclient/ops.h. Also added new files
3501 silc/local_command.[ch] and silc/client_ops.[ch].
3503 All these changes were made to make it easier for user interface
3504 designers to create what ever user interface for the SILC client
3507 It is also expected that the server will be moved to lib
3508 directory as well and SILC Server Library will be created;
3509 sometimes in the future.
3511 * Removed Local commands from lib/silccore/silccommand.h as
3512 they are application specific and new client library does not
3513 handle any of those anymore.
3515 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3516 old client implementation in silc/.
3518 * Added support for callback functions in SILC_LOG_* macros.
3519 Application can now set its own callbacks that will be called
3520 instead of using the default functions that will always print
3521 the debug messages to stderr (or stdout). Also, debugging can
3522 now be disabled by setting silc_debug to FALSE and re-enabled by
3523 setting it to TRUE. Note, that logging will still work even
3524 if debugging is disabled.
3526 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3527 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3528 silc_log_reset_debug_callbacks.
3530 * To enable debugging in silc client one must give now -d
3531 option on command line.
3533 * Changed silc_schedule_init to automatically allocate task queues
3534 if they are not allocated before calling it.
3536 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3538 * Added GMP 3.1 into math library.
3540 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3543 a channel in SILC network. The packet is used by servers and
3544 routers to notify other routers that user has left a channel.
3545 This little feature was missing until now. Added the feature
3546 to protocol specification as well.
3548 Added functions: silc_server_send_remove_channel_user and
3549 silc_server_remove_channel_user into server.[ch].
3551 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3552 lib/silccore/silcpacket.h. However, they are not implemented
3555 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Fixed joining to a channel and sending channel messages
3558 between server and router. The channel message sending should
3559 now work inside a cell.
3561 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3563 * Fixed the private message sending between server and router.
3564 The private message sending should now work inside a cell.
3566 * Added silc_server_replace_id into server.[ch] to replace
3567 existing ID in the SILC network.
3569 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3570 and silc_idlist_replace_server_id into idlist.[ch] in server.
3572 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Fixed the server to server connections. Server can again now
3575 connect to router. Router to router connections probably does
3578 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Added dynamic protocol registering support. Now protocols can
3581 registered and unregistered on the fly. Patch by cras.
3583 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Added lib/contrib directory to hold routines that some platforms
3586 don't have but are needed by SILC.
3588 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3589 into lin/contrib to provide getopt() and getopt_long() for
3590 those who don't have it.
3592 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Added AWAY command to client. When away message is set and
3595 client receives a private message packet the client automatically
3596 replies to the sender with the away message.
3598 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3599 bug seemed to be the cause of recent problems when compiling
3602 * Added version detection support to SKE protocol specification
3603 and added the new changes to the SKE implementation as well.
3604 There were other minor changes in the SKE protocol as well.
3606 Many changes in lib/silcske/silcske.[ch] and in
3607 lib/silcske/payload.[ch].
3609 * Added ^U functionality, clear input line. Patch from cras.
3611 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Mainly small bugfixes on core library. Fixed some debugging
3614 logging and buffer overflow in silclog.c.
3616 * Updated config.sub and config.guess on the distribution tree.
3618 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3620 * Added command lagging support in server. Client may execute
3621 commands now only once in two seconds.
3623 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Optimized packet reception. MAC computation and checking is now
3626 also more optimized. A lot previously duplicated code is now
3627 used as generic by both client and server.
3629 * Fixed key pair generation in clientutil.c
3631 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Added into lib/silccore/silcbufutil.[ch] new function;
3634 silc_buffer_realloc.
3636 * Moved generic packet sending/encryption functions to
3637 lib/silccore/silcpacket.[ch] from client and server. Some
3638 rewriting of the functions.
3640 * Moved all generic packet reception/decryption functions to
3641 lib/silccore/silcpacket.[ch] from client and server. The
3642 packet processing is now much cleaner in both client and server.
3643 These were major changes in both client and server.
3645 * Created many common functions in server to do packet sending.
3646 Previously code were duplicated a lot, this has been removed
3649 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3651 * Rewrote major parts of the ID cache system. Don't know
3652 whether it is better now or not but at least the API is more
3655 * Major rewrite on ID cache stuff on client because of the ID
3656 cache API changes. Added idlist.c to client.
3658 * Also major rewrite on ID cache stuff on server as well.
3659 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3660 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3661 in hand, instead they are all put into the ID cache system now.
3662 All server_idlist_* routines uses ID cache now instead of
3663 traversing its own lists (those lists does not exist anymore).
3664 SilcIDList though still exists. Also, SilcXXXEntry's are
3667 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3669 * Finally made the SKE implementation compliant to the protocol
3670 specification. All mp integers are now binary encoded as
3671 opposed being HEX encoded.
3673 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3676 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3677 functions: silc_[encode/decode]_pem. Also added function
3678 silc_encode_pem_file to PEM encode with newlines ('\n') for
3681 * SILC public keys are now encoded either PEM or binary. Same
3682 option is for private keys as well. By default private keys
3683 are binary encoded and public keys PEM encoded. Silly HEX
3684 encoding were removed.
3686 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3687 function to create fingerprints.
3689 * Fixed a bug in SHA1; does not change the original data anymore.
3691 * Partly implemented INFO command on client and server side.
3692 Fixed CLEAR command. Changes to SERVER command; show current
3693 server(s) when giving command without arguments. Added
3694 VERSION command to client.
3696 * Added check to server that unregistered connections cannot
3697 execute commands (unless it is specificly allowed).
3699 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3701 * Fixed screen refresh.
3703 * Fixed channel joining bug from client. On some circumstances
3704 client tried to join to a channel it had already joined.
3706 * Added public key verification process into client's protocol.c.
3707 The client now verifies the public key from user and saves
3708 it into ~./silc/serverkeys/ directory.
3710 Added into: clientutil.[ch]: silc_client_verify_server_key.
3712 * Changed SKE protocol's silc_ske_initiator_finish function
3713 to accept callback function that verifies the received public
3714 key. Removed old silc_ske_verify_public_key function.
3716 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3719 silc_pkcs_private_key[_data]_set.
3721 * Made the password and public authentication more cleaner in
3722 server's protocol.c.
3724 * Removed historic and obsolete protocol `channel_auth' from
3725 both client and server.
3727 * Removed wrong way of sending command status messages from
3728 server to client in server's command.c. The old way violated
3729 protocol specification.
3731 Changes to silccore/silccommand.[ch]: removed
3732 silc_command_encode_status_payload -> not needed anymore,
3733 changed silc_command_encode_payload_va to accept extra
3734 argument on variable argument list. The argument type must
3735 now be provided to the function. Also, added new function:
3736 silc_command_encode_reply_payload_va which is same as
3737 normal command_encode_payload_va except command status type
3738 is provided as extra argument.
3740 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Added ~./silc directory handling. The directory includes the
3743 public and private keys for the client.
3745 Added silc_client_check_silc_dir, silc_client_create_identifier
3746 and silc_client_load_keys.
3748 * Implemented SILC protocol compliant public key. Added public
3749 and private key saving to and loading from files.
3751 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3752 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3753 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3754 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3755 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3757 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3758 silc_pkcs_load_[public/private]_key.
3760 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Added silc_server_get_route (route.[ch]) to get connection
3763 data for the fastest route for given ID.
3765 * Implemented INVITE command on client and server. The command
3766 were re-defined in the SILC Protocol Specification and the
3767 implementation now complies with the specification.
3769 * Implemented PING command on client and server.
3771 * Implemented NAMES command on client and server. The server side
3772 supports currently only normal server not router server yet.
3773 Some changes to NAMES definition in SILC protocol specification.
3775 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3777 * Implemented LEAVE command on client and server.
3779 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3780 again. This change was made to the protocol as well. Server
3781 should not violate the protocol specification anymore.
3783 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3786 was tested. SOCKS4 was not but should work anyway.
