1 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added invite list, ban list, some key management and connection
4 error message printing to module formats in the Irssi SILC client.
6 * Added new silc_client_set_away_message to set the away message
7 that is back to the person who sent private message. The
8 affected file lib/silcclient/silcapi.h and the
9 lib/silcclient/client_prvmsg.c.
11 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
13 * Fixed the private message sending in the Irssi SILC client,
14 added local command KEY to the Irssi SILC client.
16 Added key management and key agreement message formats to the
17 irssi/src/fe-common/silc/module-formats.[ch].
19 Added USERS (alias WHO) printing, server/router operator
20 indication and LIST command printing to the module formats.
22 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
24 * Fixed channel joining notify handling, cumode notify handling
25 from Irssi SILC client.
27 * Added SILC specific module-formats to the Irssi SILC client so
28 that SILC specific message hilighting, colors etc is possible.
29 Affected file irssi/src/fe-common/silc/module-formats.[ch].
31 Added channel mode, channel user mode, actions, notices,
32 whois and whowas printing to the the module-formats.c.
34 * Fixed a bug in channel deletion in the server. The channel
35 is not left to the cache even if the channel founder auth mode
36 is set when there are no users anymore on the channel. Affected
39 * The silc_net_localhost now resolves the entire hostname including
40 the domain name. Affected file lib/silcutil/silcnet.c.
42 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
44 * Changed the ask_passphrase client operation to be ascynchronous.
45 It has now a completion callback and a context that the
46 application must call after it has got the passphrase from
47 the user. Affected files lib/silcclient/silcapi.h,
48 lib/silcclient/protocol.c, lib/silcclient/command.c and
51 Added SilcAskPassphrase callback that the application calls
52 to deliver the passphrase to the library.
54 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
55 The public key verification and especially a certificate
56 verification is asynchronous procedure.
58 Added new SILC_SKE_STATUS_PENDING status to indicate the
59 request is pending and a callback will be called to finalize
62 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
63 indicate that remote end did not send its public key (or
64 certificate), even though we require it. Added check for this
65 condition in the SKE. This was a security bug, now fixed.
67 Defined new SilcSKEVerifyCbCompletion callback that is called
68 when the verification process is completed.
70 The affected files lib/silcske/silcske_status.h and
71 lib/silcske/silcske.[ch].
73 * Changed the verify_public_key client operation to be async
74 as well. Defined SilcVerifyPublicKey callback that is used to
75 indicate the success of the public key verification process.
77 Changed the server and client to use the new async client
80 * Changed the Irssi SILC client's internal scheduler to be called
81 twice as many times as it used to be. As a result the client
82 should be a bit faster now. Affected file is
83 irssi/src/silc/core/silc-core.c.
85 * Added support to Irssi SILC client of asynchronous public key
86 verification and passphrase inquiry. Affected file is
87 irssi/src/silc/core/silc-core.c.
89 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
91 * Do not say "You have left channel %s" in client library.
92 Moved it to the application. Affected files are
93 lib/silcclient/command.c and silc/client_ops.c.
95 * Fixed silc_client_get_clients. Command context was not
96 duplicated and was freed memory in the callback. Affected
97 file lib/silcclient/idlist.c.
99 * Do not say "you are now talking..." on JOIN command in the
100 client library. The appliation must handle it.
102 * Do not say ".. changed topic to" in command reply in the
103 client libary. The application must handle it.
105 * Fixed TOPIC command sending in the client library.
107 * Fixed a memory leak in silc_client_command_free in the file
108 lib/silcclient/command.c.
110 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
112 * Imported a modified version of Irssi client to the source tree.
113 The Irssi will be used to create a new client called
114 Irssi SILC. Imported to irssi/.
116 Added silc_core_init_finish function to the Irssi. Affected
117 file irssi/configure.in.
119 A lot changes in the Makefile.ams around the irssi tree.
121 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
123 * Do not rehash if the new size is same as the old size of the
124 hash table, in the silc_hash_table_rehash*. The affected file
125 lib/silcutil/silchashtable.c.
127 * Replaced hash_table_del_by_context calls from the server
128 (when channel->user_list and client->channels) to the
129 hash_table_del as it is sufficient and faster.
131 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
133 * Added silc_hash_table_list, silc_hash_table_get and the
134 SilcHashTableList structure to provide an alternative way to
135 traverse the hash table. The affected files are
136 lib/silcutil/silchashtable.[ch].
138 * Changed the server's idlist routines to use the hash table
139 routines to optimize the code.
141 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
143 * Replaced the client entry's `channel' list and channel entry's
144 `user_list' list to hash tables for optimized lookup. Changed
145 the code to use the hash table interface around the code.
146 Affected file lib/silcd/idlist.[ch].
148 * Added `auto_rehash' boolean argument to the function
149 silc_hash_table_alloc to indicate whether the hash table should
150 auto-rehash when it thinks is appropriate time. It will
151 increase the hash table size if the there is twice as much
152 entries in the table than the size of the table, and will
153 decrease the size if there are twice as less entries than
154 the size of the table.
156 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
158 * Fixed silc_xxx_get_supported to not crash at some circumstances.
160 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
162 * silc_idcache_purge_by_context deletes the entry now by context
163 as it is supposed to do. Affected file lib/silccore/idcache.c.
165 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
166 client is not anymore valid (WHOWAS givens the info) and not
167 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
169 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
171 * Removed the `data' and `data_len' arguments from the ID Cache
172 interfaces and added `name' argument. ID Cache does not handle
173 anymore the binary data only a names associated with given ID.
175 * When hashing a Client ID with silc_hash_id the entire ID is
176 not hashed anymore, instead only the hash of the Client ID is
177 hashed. This way we can access the Client ID from the cache
178 with Client ID but with the hash of the ID (which is a hash of
179 the nickname) as well without any difference in performance.
181 Added also silc_idcache_find_by_id_one_ext to do one on one
182 searching when we have the actual ID. Added also function
183 silc_hash_client_id_compare. The affected files are
184 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
186 * When hashing the name associated with a ID it is always done
187 in lowercase. This way we can access the cache without worrying
188 about case-sensitivity, even though, for example nicknames are
191 * Fixed a bug in server with channel message sending. It put
192 wrong ID type as destination ID. The affected file
195 * silc_idcache_del_by_context now deletes from all hash tables
196 by context. Affected file lib/silccore/idcache.c.
198 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
200 * Changed the client library to use the new ID Cache interface.
201 Changes around the source tree.
203 * Added silc_hash_table_rehash_ext to rehash with specific
204 hash function. Affected file lib/silcutil/silchashtable.[ch].
206 * Added silc_hash_string_compare to compare two strings in the
207 hash table. Affected file lib/silcutil/silcutil.[ch].
209 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
211 * Added new function silc_idcache_del_by_context into the
212 lib/silccore/idcache.[ch].
214 * Changed the server's ID list routines to use the new ID Cache
215 interface. Changes around the source tree.
217 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
219 * Added silc_hash_table_del[_by_context]_ext functions in to the
220 lib/silcutil/silchashtable.[ch].
222 Removed silc_hash_table_find_all* routines and added new
223 silc_hash_table_find_foreach to replace them.
225 Added silc_hash_table_replace_ext function as extended
226 replacing function. Separated the simple hash table interface
227 from the extended hash table interface in the file
228 lib/silcutil/silchashtable.h.
230 * Fixed minor bugs and changed it to use some of the new
231 hash table functions in lib/silccore/idcache.c
233 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
235 * Added new function silc_hash_table_find_all to return all keys
236 in the hash table by the specified key. As the hash table is
237 collision resistant it also makes it possible to have several
238 duplicate keys in the hash table. This function may be used to
239 find all of the keys from the hash.
241 Added user_context arguments to the SilcHashFunction,
242 SilcHashCompare and SilcHashDestructor to deliver user specified
245 Added new fuctions silc_hash_table_find[_all]_ext to do
246 extended lookup with specified hash and compare functions and
247 specified user contexts.
249 Added new function silc_hash_table_add_ext to add the key
250 with specified hash function and user context.
252 Added new function silc_hash_table_foreach to traverse all
253 entrys in the hash table. Added SilcHashForeach callback
256 Added new function silc_hash_table_del_by_context to delete
257 the entry only if the context associated with the key matches.
259 Affected files are lib/silcutil/silchashtable.[ch].
261 * Removed silc_hash_[server/client/channel]_id and added just
262 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
263 silc_hash_id_compare to compare two ID's using as the hash table
264 comparison function. Added also silc_hash_data to hash
265 binary data and silc_hash_data_compare to compare it.
267 * Removed silc_idlist_find_client_by_hash as it is not needed
268 anymore. Affected file silcd/idlist.[ch].
270 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
271 to use internally the SilcHashTable. The new ID Cache is a lot
272 faster than the old one. Some of the ID Cache interface was also
273 rewritten and obsolete and stupid functions were removed.
275 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * Added entry_count field to the SilcHashTable to keep the number
278 of the entries in the table. Implemented the function
279 silc_hash_table_rehash. Added new function
280 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
282 Fixed a minor bug in silc_hash_table_free.
284 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
285 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
286 into the lib/silcutil/silcutil.[ch].
288 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
290 * Implemented a collision resistant hash table into the
291 lib/silcutil/silchashtable[ch]. See the header and the source
292 for the SilcHashTable API.
294 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
296 * Merged dotconf version 1.0.2 into lib/dotconf.
298 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
300 * Do not compile anything in lib/silcsim/* if the SIM support
301 is not enabled. The tree should now compile without problems
304 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
306 * Compiled the SILC under cygwin. Compiled and tested briefly
307 without problems. More tests needed. The SIMs didn't compile
310 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
312 * Fixed possible crash in silc_get_username in the
313 lib/silcutil/silcutil.c.
315 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
317 * Fixed a va_arg in silc/client_ops.c.
319 * Oops, RC5 routines were named AES and caused some problems
320 when not using SIM's. Affected file lib/silccrypt/rc5.c.
322 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
324 * Added new SilcIDIP structure into the lib/silccore/id.h and
325 replaced the old `ip' fields from all SILC ID's to that type.
326 This is a step towards IPv6 support.
328 The silc_id_get_len takes now the ID as an extra argument.
329 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
330 both IPv4 and IPv6 based ID's.
332 The affected files are lib/silccore/id.[ch] and other files
333 around the tree using these routines.
335 * Removed the ID length arguments in server from various
336 silc_server_send_notify_* routines -> they are not needed
339 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Fixed memory leak in silc_encode_pem_file in the file
342 lib/silcutil/silcutil.c.
344 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
346 * Check minor version as well in the SKE. Affected files are
347 silcd/protocol.c and lib/silcclient/protocol.c.
349 * Added --identifier option to the server so that an identifier
350 can be when creating the public key for the server. Affected
351 file is silcd/silcd.c.
353 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
354 lib/silccrypt/silcpkcs.c.
356 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * Register default ciphers and stuff when using -C option with
359 the server. Affected file sildc/silcd.c.
361 * Put back the servers public key filename format, it is better
362 than the new one. For now, the client keys are saved with the
363 new filename format. The affected file silc/client_ops.c.
365 * Implemented the Cipher API for the rest of the ciphers that
366 did not implement it or implemented it the wrong way.
368 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
370 * Register default ciphers and stuff when using the -S option
371 in the client. Affected file silc/silc.c. Same also when
372 creating new key pair with -C option.
374 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
376 * Fixed the silc_verify_public_key client operation function to
377 save the public keys differently. The fingerprint is now
378 used as filename and not the hostname. This way also the
379 client keys are saved uniquely and not with hostnames. The
380 affected file is silc/client_ops.c.
382 * Trimmed the silc_hash_fingerprint function to remove extra
383 whitespaces from the end of the fingerprint. The affected
384 file is lib/silccrypt/silchash.c.
388 * Added silc_cipher_register_default function to register all
389 default ciphers. It can be used when configuration files
390 does not exist and the application does not want any specific
391 ciphers in any specific order.
393 The SilcDList is now used as silc_cipher_list dynamically
394 allocated cipher list. Removed the static list all together
395 and now all ciphers must be allocated to the dynamic list.
396 The silc_cipher_alloc routine was changed to check only the
399 All silc_cipher_* routines that used to return int returns
402 The affected files lib/silccrypt/silccrypt.[ch].
404 * The same thing was done to silc_hash_* as for silc_cipher_*
405 routines. Affected files lib/silccrypt/silchash.[ch].
407 * The same thing was done to silc_pkcs_* as for silc_cipher_*
408 routines. Affected files lib/silccrypt/silcpkcs.[ch].
409 Added also silc_pkcs_[un]register[_default] functions.
410 Removed the data_context from the PKCS API.
412 * Added silc_hmac_register_default function to register default
413 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
414 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
415 to unregister all hmacs at once.
417 * Register the default ciphers, hash functions, PKCSs and HMACs
418 if client's configuration file does not exist. The affected
421 * The client did not load the hash functions from the SIM
422 modules at all. Added support for this. Affected file is
425 * When decoding public key with silc_pkcs_public_key_decode, check
426 the supported algorithm only if PKCS are registered. Affected
427 file lib/silccrypt/silcpkcs.c. The same was done with the
428 silc_pkcs_private_key_decode.
430 * Fixed the SILC List routines to keep the list always in order.
431 It used to change the list's order when traversing the list but
432 not it preserves the order. Affected file lib/trq/silclist.h.
434 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
436 * Added the client library to use the SilcSocketConnection's
437 reference counter (by silc_socket_dup) to prevent the bug that
438 the socket object may be freed underneath async operation.
440 * The name resolv library checking fixes in the configure.in.pre.
443 * Created new version of the protocol drafts for future
444 development. The -03 drafts are the ones that will be changed
445 in the trunk now and the -02 will remain as they are.
447 * Send list of CUMODE notifys to the router when announcing
448 the channel users to the router. Affected file silcd/server.c.
449 If the router receiving channel founder CUMODE for a channel
450 that already has channel founder it will send CUMODE notify
451 to the sender to remove the channel founder rights from the
452 announced client. Affected file silcd/packet_receive.c.
454 * The CUMODE notify may now use Server ID as well as the entity
455 who changes the mode. Updated protocool specs.
457 * Updated INSTALL and README files.
459 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
461 * New web pages in the http://silc.pspt.fi. The pages was
466 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
468 * Implemented the [DenyConnectin] config section in the server.
469 Added silc_server_config_denied_conn to check whether incoming
470 connection is denied. Affected file silcd/serverconfig.[ch].
472 * Do not check the ports when checking the incoming configuration
473 data if the port is 0, meaning any. Affected file is
474 silcd/serverconfig.c.
476 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
478 * Fixed buffer overflow in silc_string_compare in the file
479 lib/silcutil/silcutil.c.
481 * Fixed double free in silc_server_command_leave in the file
484 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
486 * Fixed the version checking in the server. Affected file is
489 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
491 * Fixed the configuration data fetching when accepting new
492 connections in the server. Affected file silcd/server.c.
494 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
496 * Added `sender_entry' argument to the function
497 silc_server_packet_relay_to_channel so that we can check
498 whether some destination actually belongs to the same route
499 the sender belongs (ie, we must not resend the packet to the
500 sender). Affected file silcd/packet_send.[ch].
502 * Added `servername' field to the SilcClientEntry in the server
503 to hold the name of the server where client is from. Affected
504 file is silcd/idlist.h.
506 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
508 * Moved the channel message encrypting in the router betwen
509 router connections from silc_server_channel_message to the
510 silc_server_packet_relay_to_channel since we want to check
511 whether we have anybody channel before encrypting anything.
512 Affected files silcd/packet_[receive/send].c.
514 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
516 * Fixed the [AdminConnection] server config section to support
517 multiple entries. Affected file silcd/serverconfig.c.
519 * Added support into the server to check the validity of the
520 incoming connection before executing any KE or authentication
523 * The connection configuration is now saved to the KE and
524 connection auth protocol contexts and not fetched anymore in
525 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
527 * The local hosts listenning address and port is also resolved
528 now when starting the server. We want to have the socket object
529 to include the real address and port for the listener. Added
530 new function silc_net_check_local_by_sock into the files
531 lib/silcutil/silcnet.[ch].
533 * Fixed a broadcast bug in server -> do not broadcast if we
536 * Fixed a routing bug. Do not route broadcast packets ever.
537 Broadcast packets must be processed always and not routed since
538 they may be destined to some other host than yourself and thus
539 would get routed without no good reason. Affected file is
542 * Added function silc_server_config_is_primary_route to check
543 whether primary router connection has been configured (a router
544 configuration that we are initiating). If there is not, we
545 will assume that there is only two routers in the SILC network
546 and we will use the incoming router connection as our primary
547 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
549 * Changed the order of the broadcasting. Broadcast _after_ the
550 packet has been processed not before. Affected file is
553 * Fixed a [ClientConnection] parsing bug. The port was never
554 parsed correctly thus resulting to port 0. Affected file
555 silcd/serverconfig.c.
557 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
558 argument and did not set the broadcast packet flag. Affected
559 file silcd/packet_send.c. Fixed same bug in the function
560 silc_server_send_notify as well.
562 * If we receive NEW_ID packet for our own ID in the server, ignore
565 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
569 * Removed the nickname from the Private Message Payload.
570 Updated the code and the protocol specs.
572 * Updated protocol specs for submitting to the IETF.
574 * Tweaked the Random Number Generator a bit. Affected file
575 lib/silccrypt/silcrng.c. Exported a new function
576 silc_rng_[global]_add_noise which can be used to add more
579 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
581 * Do not parse packets with different timeout when protocol
582 is active -> may cause problem with rekey. Affected file
585 * When server receives signoff notify it must not create
586 new channel key if the client is on any channels since the
587 sender of the signoff notify will create it.
589 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
591 * Added printing of error messages during SKE protocol from the
592 failure packet sent by server during SKE. Affected file
595 * Removed the client's failure_callback handling with timeout
596 and handle it immediately when received.
598 * The SKE library returned wrong type in SUCCESS and FAILURE
599 packets. They must be 32 bit MSB not 16 bit MSB.
601 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
603 * Ok, rewrote the logic of the re-key and now it seems to work.
604 I tested it on high traffic with frequent re-keys without
605 problems. Added hmac_receive (and renamed hmac to hmac_send)
606 in SilcClientConnection in lib/silcclient/client.h and
607 in SilcIDListData in silcd/idlist.h. Also, removed the
608 SilcPacketParserContext's cipher and hmac fields as they are
609 not needed anymore and actually caused some problems when
610 the ciphers and hmac's changed underneath the packet parser.
612 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
614 * If re-key protocol is active then process the incoming packets
615 synchronously since we must assure that icoming packets encrypted
616 with the old key is processed before the new keys is set to
617 use. This is true other packets than for REKEY packets.
618 Affected file silcd/server.c. The same was done to client library
619 as well, affected file lib/silcclient/client.c.
621 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Fixed bug in client and server to accept the force send if
624 the packet is send from silc_[server/client]_packet_process
625 function. Otherwise the packets are never delivered, oops.
627 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
629 * Disable force sending of packets when REKEY protocol is active.
630 We must assure that no packet is sent directly when rekey is
631 performed. All packets must be sent through packet queue.
632 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
633 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
634 function is silc_[server/client]_packet_send_real to check
637 * Replaced the SIM paths from example config files to
638 /usr/local/modules. Also, make install creates now
639 /usr/local/silc/logs directory to hold all the SILC server
642 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
644 * Made the configure.in.pre work on Solaris. Patch by salo.
646 * Made all ciphers compatible with non-x86 machines. Defined
647 CBC mode macros into lib/silccrypt/ciphers_def.h.
649 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
651 * Fixed the make install.
653 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
655 * When MAC computation fails the silc_packet_decrypt returned 0
656 even though it was supposed to return -1. Fixed this. The
657 affected file is lib/silccore/silcpacket.c.
659 * Do not replace the config files in /etc/silc (in make install)
660 if they already exist. Affected file ./Makefile.am.
662 * Do not send re-key packets immediately but through packet queue.
663 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
665 * Changed silc_net_check_host_by_sock to return FALSE if the
666 IP/DNS could not be resolved. Though, it returns the IP address
667 now even if it could not resolve it (but returns also FALSE).
668 Affected file lib/silcutil/silcnet.[ch].
670 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
672 * Added silc_pkcs_decode_identifier to decode the public key's
673 identifier. Affected file lib/silccrypt/silpkcs.[ch].
674 Added also silc_pkcs_free_identifier. Added also new context
675 SilcPublicKeyIdentifier.
677 * Added -S option to the silc client. It is used to dump the
678 contents of the specified public key file.
680 * Changed the PKCS api to return the public key length when
681 setting the public key.
683 * Fixed a fatal bug in the public and private key file loading.
684 Affected file lib/silccrypt/silcpkcs.c.
686 * Execute the packet parsing for client with zero (0) timeout
687 if the protocol is active. Affected file silcd/server.c.
689 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
691 * Made the key generation options to the silcd program. Added
692 -C option, equivalent to client's option.
694 * Added new [ServerKeys] config section to the server. It
695 configures the server's public and private key.
697 * Defined generic Public Key Payload into the protocol
698 specification to send specific type of public keys and
701 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
702 public key or certificate.
704 * Implemented the GETKEY command to the server and to the
705 client library and on user interface.
707 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Made preliminary `make install' work.
711 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
713 * Added SilcServerRekey context into silcd/idlist.h.
715 * Added the PFS support as defined in the specification to the
716 SKE protocol. Affected files lib/silcske/*.c.
718 * Added `ske_group' field to the SilcServerRekey context to hold
719 the number of the SKE group that is used with PFS in re-key.
720 Affected file silcd/idlist.h.
722 * Added PFS re-key support to the server. Affected file is
725 * Added silc_protocol_cancel to cancel execution of the next
726 state of the protocol. Affected file is
727 lib/silccore/silcprotocol.[ch].
729 * Added the re-key support with and without PFS to the client
730 library. Re-key is performed once in an hour, by default.
732 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
733 Added silc_client_rekey_callback and silc_client_rekey_final.
734 Affected files are lib/silcclient/protocol.[ch] and
735 lib/silcclient/client.[ch].
737 * Removed the `hmac_key' and `hmac_key_len' fields from the
738 SilcClientConnection structure; not needed. Affected file is
739 lib/silcclient/client.h.
743 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
745 * Do not ask whether user wants to use the negotiated private key
746 for private messages, just use it. Affected file is
747 silc/local_command.c.
749 * Added `send_enc_key' and `enc_key_len' fields to the
750 SilcIDListData structure since they are needed in the re-key
751 phase. Affected file is silcd/idlist.[ch].
753 * Implemented the simple re-key protocol into the server.
754 Affected files silcd/server.c and silcd/protocol.[ch]. The
755 re-key will be performed once in an hour, by default.
757 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
758 Added silc_server_rekey, silc_server_rekey_callback and
759 silc_server_rekey_final.
761 * Removed Tunneled flag from the protocol. Updated the code
762 and the specifications.
764 * Adde `pfs' field to the SilcIDListData to indicate whether
765 the PFS is to be performed in the re-key. Affected file is
768 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
771 int64 of at least the xintXX size. If void * is less that 4
772 bytes uint32 * will be used. Defined bool as boolean.
774 * Changed _ALL_ unsigned long and unsigned int to uint32,
775 unsgined short to uint16 in the source tree.
777 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
778 not handle clients that has entry->data.registered == FALSE.
779 They are not in the network anymore. Affected file is
782 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
784 * Implemented the sending of the SERVER_SIGNOFF notify in the
785 server. Affected file is silcd/server.c.
787 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
788 Added also silc_notify_payload_encode_args into the
789 lib/silccore/silcnotify.[ch].
791 * Implemented ther SERVER_SIGNOFF notify handling in the server.
792 Affected file silcd/packet_receive.c.
794 * Implemented the SERVER_SIGNOFF notify handling in the client
795 library. Affected file lib/silcclient/client_notify.c. Also,
796 implemnted the printing of the SERVER_SIGNOFF info to the
797 application. Affected file silc/client_ops.c.
799 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
800 if the deleting was successful. Affected file silcd/idlist.[ch].
802 * Added support for public key authentication in the connection
803 authentication protocol in the client library. Affected file
804 lib/silcclient/protocol.c.
806 * Changed the server's silc_idlist_get_clients_by_* interface
807 to support already allocated array so that new entries may be
808 added to pre-allocated array. Affected file silcd/idlist.[ch].
809 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
812 * All command reply functions in the server now calls the
813 pending command callback even if error occured. This way the
814 error will be delivered to the client as well. Affected files
815 silcd/command.c and silcd/command_reply.c.
817 * Fixed INFO command to return local server's info if no server
818 was provided. Affected file lib/silcclient/command.c.
820 * Removed RESTART command for good. Updated the code and the
823 * Rewrote parts of the task system. It is a bit simpler now.
824 Removed unsued task priorities. The affected files are
825 lib/silcutil/silctask.[ch].
827 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * Moved the USERS printing from the library to the application.
830 Affected files lib/silcclient/command.c and silc/client_ops.c.
832 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Added channel key re-key support. The re-key is perfomed
837 only by the router and is done once in an hour. Added `rekey'
838 field to the SilcChannelEntry in the server. Affected files
839 silcd/server.c and silcd/idlist.h.
841 * Added silc_task_unregister_by_context into the file
842 lib/silcutil/silctask.[ch].
844 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
846 * Added SILC_UMODE_GONE mode to indicate when the client is not
847 present in the SILC network. Added also support to the local
848 command AWAY that will set this mode. Added support of showing
849 "xxx is gone" in WHOIS command. The USERS command shows the
852 * Fixed setting server and router operator privileges in the
853 server's UMODE command. Affected file silcd/command.c.
855 * Merged the SKE KE1 and KE2 payloads into one payload. The
856 new KE payload is equivalent to the old KE2 payload.
858 Cleaned up the SKE Start Payload parsing. It now uses the
859 simple buffer unformatting to do the parsing. A lot faster
862 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
863 to the SKE that is used to indicate whether both of the SKE
864 parties should perform authentication. By default only the
865 responder performs authentication. By setting this flag also
866 the initiator must do authentication. By default it is unset
867 since in normal SKE case, client to server connection, only
868 the responder should do authentication. When doing SKE between
869 two clients both should perform authentication. Updated the
870 code and the protocol specs.
872 * A little fix to IDENTIFY command in the server. Search the
873 client first by hash not nickname. Affected file is
876 * Fixed the silc_client_close_connection to support closing
877 the client to client connections wihtout deleting too much
878 data. Affected file lib/silcclient/client.c.
880 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
881 are received if protocol used to be active but is not anymore
882 the application would crash due to NULL pointer dereference.
883 Affected files silcd/server.c and lib/silcclient/client.c.
885 * Added `hash' field to the SilcClientConnection to include
886 the hash function negotiated in the SKE protocol.
888 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
889 to set the channel founder authentication data. A client can
890 claim the founder rights later by providing the authentication
891 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
892 This way the channel founder can regain the channel founder
893 privileges even it is left the channel. This works only on
894 local server and the client must be connected to the same
895 server to be able to regain the founder rights. Updated the
896 protocol specs accordingly.
898 Added support to the CMODE command in the client to set the
899 founder auth data. Read the README to see how to set it.
901 Added support to the CUMODE command to claim the founder
902 rights. Read the README to see how to do it.
904 Added support for the founder authentication to the Channel
905 Entry in the server. Affected file silcd/idlist.h.
907 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
908 server's CMODE command. Affected file silcd/command.c.
910 * Added the following new functions into lib/silccore/silcauth.[ch]:
911 silc_auth_get_method and silc_auth_get_data.
913 * The server now saves the remote hosts public key to the
914 SilcIDListData pointer. Affected file silcd/protocol.c.
916 * The normal server now does not remove the channel entry from
917 the cache if the founder authentication data is set. It used
918 to remove it if the founder was the last one on the channel on
919 the server and left the channel. The auth data is saved and
920 if the channel is re-joined later the old entry is used with
921 the old auth data. Affected files silcd/command_reply.c and
924 * Removed the `pkcs' field from the SilcIDListData structure
925 in the server; it is not used. Affected file silcd/idlist.h.
927 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
929 * Fixed packet processing on slow links. Partial packets were
930 never re-processed because the incoming data buffer was cleared
931 by the application. Application must not directly clear the
932 sock->inbuf, the packet processing routines handle it. Fixed
933 this in client library and in server.
935 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
937 * Fixed the WHOIS and IDENTIFY send reply function to really
938 check whether to send list or just one entry. Affected file
941 * Cleaned up the LEAVE command's channel key distribution. The
942 affected file silcd/command.c.
944 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
945 can enforce the channel mode as well. In that case the ID
946 includes the ID of the server. The code now enforces the
947 mode change if the router have different mode than the server.
949 * The notify client operation with CMODE_CHANGE notify can now
950 return NULL client_entry pointer if the CMODE was not changed
951 by client. Application must check for this.
953 * Added <Server ID> argument to INFO command to support server
954 info fetching by Server ID.
956 * Added silc_server_announce_get_channel_users to get assembled
957 packets of channel users of the specified channel. Affected
958 file silcd/server.[ch].
960 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
961 was freed underneath the ID Cache.
963 * Re-announce clients when the server received CHANNEL_CHANGE
964 notify from the router. Affected file silcd/packet_send.c.
966 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
968 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
969 crashed since it did not handle the fact that there is no cipher
970 called "3" and didn't check the error condition. Now fixed.
972 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
973 flag. It can be used to send message requests.
975 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
977 * Implemented the RESTART command in the client.
979 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
980 notice type messages. Added notice printing to the user
983 * The channel keys are not re-generated if the channel's mode
984 is PRIVKEY, ie private key on the channel exists. Affected
985 files silcd/server.c and silcd/command.c.
987 * Fixed a little bug in channel message delivery when channel
988 private keys are set in the server. Affected file is
991 * Changed the setting on channel->on_channel = TRUE from the
992 silc_client_save_channel_key to the JOIN command reply. The
993 key payload is not received if the private channel key is set.
994 Affected file lib/silcclient/command_reply.c and the
995 lib/silcclient/client_channel.c.
997 * When the CMODE_CHANGE notify is sent and the channel private
998 key mode is removed the channel key must be re-generated in
999 other cells as well. Added this support for the router in the
1000 silcd/packet_receive.c.
1002 * Added new local command NOTICE to send notice message on
1003 channel. Affected file silc/local_command.[ch].
1005 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1007 * Added new local command ME to the client. It is used to send
1008 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1009 some action. Affected file silc/local_command.[ch].
1011 * Changed channel_message and private_message client operations
1012 to deliver the message flags to the application. Added also
1013 the `flags' arguments to the silc_client_send_channel_message
1014 and silc_client_send_private_message functions. Affected file
1017 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1019 * Redefined the Private Message Payload to support private message
1020 keys and to support the new private message flags. Updated
1021 the protocol specs. Flags makes it possible to have for example
1022 CTCP style messages.
1024 * Added new type SilcPrivateMessagePayload and defined an API
1025 for it in the lib/silcclient/silcprivate.[ch].
1027 * Tested private message private keys successfully. Tested the
1028 private message key set, unset and list commands with the new
1031 * Redefined the Channel Message Payload to include the channel
1032 message flags (equal with private message flags) to support
1033 for example CTCP style messages.
1035 * Defined some of the message (for channel and private message)
1036 flags. Updated the protocol specs and added the flags to the
1037 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1039 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1041 * Added SilcKeyAgreementStatus type to the key agreement routines
1042 to indicate the current status and error if one occured.
1043 The status types are defined in the lib/silcclient/silcapi.h.
1045 * Added new local command KEY that is used to set and unset private
1046 keys for channels, set and unset private keys for private messages
1047 with remote clients and to send key agreement requests and
1048 negotiate the key agreement protocol with remote client. The
1049 key agreement is supported only to negotiate private message keys,
1050 it currently cannot be used to negotiate private keys for channels,
1051 as it is not convenient for that purpose.
1053 * Fixed a minor pending callback setting bug in the function
1054 silc_client_get_client_by_id_resolve, now the function works.
1055 Affected file lib/silcclient/idlist.c.
1057 * Added function silc_net_get_local_port to get local bound
1058 port by socket. Added to lib/silcutil/silcnet.[ch].
1060 * Added `sockets' and `sockets_count' fields to the SilcClient
1061 object. They hold the sockets of the listenning sockets in
1062 the client. Listenning sockets may be for example the key
1063 agreement server. Affected file lib/silcclient/client.[ch].
1064 Added functions the silc_client_add_socket and the
1065 silc_client_del_socket. They are exported to the application
1068 * Added ~./silc/clientkeys to support other client's public keys.
1070 * Renamed verify_server_key client operation to verify_public_key
1071 and added one argument to indicate the type of the connection
1072 (server, client etc.).
1074 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1076 * Added silc_server_connection_auth_request to handle the
1077 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1078 silcd/packet_receive.[ch].
1080 * Added silc_server_send_connection_auth_request into the
1081 silcd/packet_send.c to send the connection auth request packet.
1083 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1086 * Fixed the public key authentication in responder side in the
1087 server. The `auth_data' pointer includes the SilcPublicKey
1088 not the path to the public key. Affected file silcd/protocol.c.
1090 * Implemented the public key authentication in the initiator side
1091 in the server. Affected file silcd/protocol.c.
1093 * Removed the [RedirectClient] config section from the server
1094 configuration. Is not needed and I don't want to implement it.
1096 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1098 * Cleaned up the CMODE command in the server. It now works
1099 correctly and supports all the modes defined in the protocol.
1100 Affected file is silcd/command.c.
1102 * Added `hmac_name' field to the SilcChannelEntry in the server
1103 to hold the default HMAC of the channel. It can be set when
1104 creating the channel (with JOIN command). Affected files
1107 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1108 type to indicate the change of the current cipher and hmac
1109 on the channel. Client can safely ignore the <cipher> argument
1110 (if it chooses to do so) since the CHANNEL_KEY packet will
1111 force the channel key change anyway. The <hmac> argument is
1112 important since the client is responsible of setting the new
1113 HMAC and the hmac key into use.
1115 * Fixed the CMODE command in the client library as well.
1117 * Tested CMODE command in router environment successfully.
1119 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1121 * Show the version of the remote client (or server) when connecting
1122 to the server. It is logged to the log file. Affected file
1123 is silcd/protocol.c.
1125 * Fixed the KILLED notify handling in the client library. The
1126 client must be removed from all channels when receiving the
1129 Also, do not remove the client entry when giving the KILL
1130 command but when the KILLED notify is received.
1132 * Removed silc_idlist_find_client_by_nickname from the server.
1133 Not needed anymore. Affected files silcd/idlist.[ch].
1135 * Implemented the CHANNEL_CHANGE notify type handling to the
1136 server. Affected file silcd/server.c.
1140 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

1149 * Implemented the INVITE command to the client library and on the
1152 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Added function silc_server_get_client_resolve to find the
1155 client entry by ID from all ID lists and then resolve it
1156 (using WHOIS) if it cannot be found. Affected file is
1159 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1161 * Implemented the BAN command to the client library.
1163 * The JOIN command in the server now checks the invite list
1166 * Changed the silc_command_reply_payload_encode_va and the
1167 silc_command_payload_encode_va to support that if argument is
1168 NULL it ignores and checks the next argument. Affected file
1169 lib/silccore/silccommand.c.
1171 * Added silc_server_send_notify_ban to send the BAN notify
1172 type between routers.
1174 * Chaned the silc_notify_payload_encode to support that if
1175 argument is NULL it ignores and checks the next argument.
1176 Affected file lib/silccore/silcnotify.c.
1178 * Tested ban lists in router environment successfully.
1180 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Implemented BAN command to the server, in silcd/command.[ch].
1184 * Removed the BAN and INVITE_LIST modes from the CMODE command
1187 * Added function silc_string_match to regex match two strings.
1188 Affected files lib/silcutil/silcutil.[ch].
1190 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1192 * Redefined parts of the SilcChannelEntry in the server to support
1193 the new ban and invite lists.
1195 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1197 * Redefined the INVITE command. The same command can be used to
1198 invite individuals to the channel but also to manage the invite
1199 list of the channel (to add to and remove from the invite list).
1200 Updated the protocol specs.
1202 * Added new command SILC_COMMAND_BAN that can be used to manage
1203 the ban list of the channel. Updated the protocol specs.
1205 * Removed the channel modes: the SILC_CMODE_BAN and the
1206 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1207 in the CMODE command. The equivalent features are now available
1208 using INVITE and BAN commands. Updated the protocol specs.
1210 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1211 in the network about change in the current ban list. The notify
1212 type is not used by the client.
1214 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1215 support the invite lists.
1217 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1219 * Added new function silc_string_regexify that converts string
1220 including wildcard characters into regex string that can
1221 be used by the GNU regex library. Added into the file
1222 lib/silcutil/silcutil.[ch].
1224 Added silc_string_regex_combine to combine to regex strings
1225 into one so that they can be used as one regex string by
1226 the GNU regex library. Added into the file
1227 lib/silcutil/silcutil.[ch].
1229 Added silc_string_regex_match to match two strings. It returns
1230 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1232 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1234 * Imported GNU regex to the soruce tree into lib/contrib.
1235 Fixed some compiler warning from the regex.c.
1237 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1239 * Fixed MOTD command in the server to work in router environment.
1241 * Fixed the MOTD command in the client library to support
1242 the server argument in the command.
1244 * Added `nickname_len' argument to the silc_idlist_add_client
1245 in the server, as the `nickname' argument may be binary data
1248 * Added silc_idlist_get_channels to return all channels from
1251 * Implemented LIST command to the server. Affected file is
1254 * Implemented the LIST command to the client library and on the
1257 * Added [<user count>] argument to the LIST command reply.
1258 With private channels the user count is not shown.
1260 * Updated TODO and README.
1262 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1264 * The client entry's data.registered must be TRUE even with
1265 global client entry on global client list. The data.registered
1266 is used to check whether the client is anymore in the network,
1267 for example with WHOWAS command so it must be valid.
1269 * Fixed the WHOWAS command in the server. It now actually works
1270 in router environment. Added function into silcd/command_reply.c
1271 silc_server_command_reply_whowas_save.
1273 * Added silc_idlist_purge function to the silcd/idlist.c
1274 to periodically purge the ID Cache.
1276 * Fixed INFO command in the server. It works now in router
1277 environment. Added <server name> argument to the INFO command
1278 reply. Updated the protocol specs.
1280 * Fixed minor bug in silc_idcache_purge to not purge if the
1281 expire value is zero.
1283 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1284 they were buggy because of the WHOWAS information.
1286 * Fixed local command MSG to handle the async resolving of
1287 the remote client properly. It used to fail the first MSG.
1288 Affected file silc/local_command.c.
1290 * Added `data_len' field to SilcIDCache context.
1292 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1294 * Update TODO. Todo in commands in the server.
1296 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1299 used by routers as broadcast packet to inform other routers
1300 about the changed user mode.
1302 Implemented the notify handling in the server. Affected file is
1303 silcd/packet_receive.c. Added the function
1304 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1306 * Added new generic Channel Payload and deprecated the New Channel
1307 Payload. The New Channel Payload is now the generic Channel
1310 * Added new argument `mode' to the silc_server_send_new_channel
1311 as it is required in the Channel Payload now.
1313 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1314 and created a new and real SilChannelPayload to represent the
1315 new generic Channel Payload. Implemented the encode/decode
1316 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1318 * Added silc_server_get_client_channel_list to return the list
1319 of channels the client has joined for WHOIS command reply.
1320 Affected file silcd/server.[ch].
1322 * Implemented the channel list sending in the WHOIS command reply
1323 in server and in the client.
1325 Implemented the channel list displaying on the user interface
1326 as well. Affected file silc/client_ops.c.
1328 * Added silc_channel_payload_parse_list to parse list of Channel
1329 Payloads. It returns SilcDList list of SilcChannelPayloads.
1330 Client for example can use this function to parse the list of
1331 channels it receives in the WHOIS command reply. The caller
1332 must free the list by calling silc_channel_payload_list_free.
1333 Affected files lib/silccore/silcchannel.[ch].
1335 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Added one new argument <user mode> to the WHOIS command reply
1338 to return the mode of the user in SILC. Updated the protocol
1341 Implemented it to the server and client.
1343 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1345 * Fixed the mode printing on the user interface on joining.
1346 Affected file silc/client_ops.c.
1348 * Implemented the UMODE command and user modes in general to the
1349 client library and to the user interface.
1351 * Implemented the UMODE command to the server.
1353 * The server now sends UNKNOWN_COMMAND error status if client sends
1354 unknown command. Affected file silcd/command.c.
1356 * All server commands now handle the command identifier the right
1357 way when sending the command reply to the client. The client can
1358 use to identify the command replies with the identifier.
1360 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1362 * Added silc_server_get_client_route to resolve the route to
1363 the client indicated by the client ID. Affected file is
1366 * Added silc_server_relay_packet as general function to relay
1367 packet to arbitrary destination. This deprecates functions
1368 like _send_private_message_key, _relay_notify etc. Affected
1369 file is silcd/packet_send.[ch].
1371 Removed silc_server_send_key_agreement,
1372 silc_server_send_private_message_key and
1373 silc_server_packet_relay_notify functions from the file
1374 silcd/packet_send.[ch].
1378 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1379 server. Affected file silcd/packet_receive.[ch].
1381 * Implemented the KILL command to the client. Implemented the
1382 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1383 Affected files lib/silcclient/command[_reply].c and
1384 lib/silcclient/client_notify.c. Implemented the KILL notify
1385 printing in the user inteface.
1387 * Fixed a lot silc_parse_nick memory leaks from the client
1388 library in the file lib/silcclient/command.c.
1390 * Changed the silc_server_send_notify_on_channels's `sender'
1391 argument from SilcSocketConnection to SilcClientEntry to
1392 check the sender as entry and not as connection object and not
1393 to send to the client provided as argument. The affected file
1394 is silcd/packet_send.[ch].
1396 * The notify packets that are destined directly to the client used
1397 to not to be processed by the server. Now changed that and the
1398 server processes all notify packets. After relaying the packet
1399 to the client the notify packet is processed in the server.
1401 * The silc_server_free_client_data now checks whether there is
1402 pending outgoing traffic for the client and purges the data to
1403 the network before removing the client entry.
1405 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1407 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1408 an client is killed from the SILC Network. Updated the protocol
1411 Added new function silc_server_send_notify_killed to the
1412 silcd/packet_send.[ch].
1414 * Added function silc_server_packet_relay_notify to relay notify
1415 packets that are destined directly to a client. In this case
1416 the server does not process the notify packets but merely relays
1417 it to the client. Affected file silcd/packet_send.[ch].
1419 Added also silc_server_packet_process_relay_notify to check
1420 whereto relay the notify. Affected file is
1421 silcd/packet_receive.[ch].
1423 * Implemented the KILL command to the server.
1427 * Added the backup schema desgined last fall to the protocol
1428 specs for everyone to see. The specification is in the
1429 *-spec-xx.txt draft and the packet type definitions for the
1430 backup routers is in *-pp-xx.txt draft. Thusly, added also
1431 new packet type SILC_PACKET_CELL_ROUTERS.
1433 * A big security problem in the implementation discovered. The
1434 signoff of an client did not cause new channel key generation
1435 which it of course should've done. The channel keys must be
1436 always re-generated when client leaves (or signoffs) the channel.
1437 The silc_server_remove_from_channels funtion now handles
1438 the channel key re-generation.
1440 * Added `sender' argument to the silc_server_send_notify_on_channels
1441 to not to send the client provided as argument. Affected file
1442 silcd/packet_send.[ch].
1444 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1446 * Implemented OPER and SILCOPER commands into the server and
1449 * Added silc_auth_verify and silc_auth_verify_data to verify
1450 the authentication directly from the authentication payload.
1451 It supports verifying both passphrase and public key based
1452 authentication. Affected file lib/silccore/silcauth.[ch].
1454 * Added `hash' field to the SilcIDListData structure. It is the
1455 hash negotiated in the SKE protocol. Affected file is
1458 * Slight redesigning of the SilcAuthPayload handling routines.
1459 Do not send SilcPKCS but SilcPublicKey as argument.
1461 * Implemented the public key authentication support to the
1462 serverconfig. The public key is loaded from the provided path
1463 and saved as authentication data to void * pointer. Thus,
1464 changed the unsigned char *auth_data to void *auth_data;
1466 * Fixed SHUTDOWN command to send the reply before the server
1467 is shutdown. :) Affected file silcd/command.c.
1469 * Fixed fatal bug in CONNECT command. The hostname was invalid
1470 memory and server crashed. Affected file silcd/command.c.
1472 * Fixed fatal bug in CLOSE command. The server_entry became
1473 invalid but was referenced later in the command. Affected file
1476 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1478 * Fixed fatal bug in failure packet handling. Server ignored
1479 the failure and thus crashed when it came.
1483 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1485 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1486 that the command may be executed only once in (about) 2 seconds.
1487 The old SILC_CF_LAG flag is same but allows command bursts up
1488 to five before limiting.
1490 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1491 server code. Various commands now includes the CF_LAG_STRICT
1492 flag to disallow any kind of miss-use of the command.
1494 * Fixed the silc_buffer_unformat to not to allocate any data
1495 if the length of the data is zero. It used to allocate the
1496 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1498 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * Changed the format of AdminConnection configuration section
1501 in the server. Added username of the admin to the format.
1502 Affected files silcd/serverconfig.[ch].
1504 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1505 to return admin configuration data by host, username and/or
1508 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * Implemented WHOWAS command to the server. Added the functions:
1512 silc_server_command_whowas_parse,
1513 silc_server_command_whowas_send_reply,
1514 silc_server_command_whowas_from_client and
1515 silc_server_command_whowas_from_server
1517 * Added <Client ID> argument to the WHOWAS command reply. Updated
1518 the protocol specs accordingly.
1520 * Implemented WHOWAS command and command_reply to the client
1523 Implemented the WHOWAS printing on the user interface.
1525 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Added new argument to the WHOWAS command reply, the real name.
1528 It is an optional argument. Updated the protocol specs.
1530 * Added SilcIDCacheDestructor callback that is registered when
1531 the SilcIDCache is allocated. The callback is called when
1532 an cache entry in the ID Cache expires, or is purged from the
1533 cache. Added into lib/silccore/idcache.[ch].
1535 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1536 to destruct the client entries when the cache entry expires.
1537 Other ID Cache's in server and in the client library ignores
1540 * If the ID Cache entry's `expire' field is zero then the entry
1541 never expires. Added boolean `expire' argument to the
1542 silc_idcache_add function in the lib/silccore/idcache.[ch].
1543 If it is TRUE the default expiry value is used.
1545 * Added silc_server_free_client_data_timeout that is registered
1546 when client disconnects. By default for 5 minutes we preserve
1547 the client entry for history - for WHOWAS command.
1549 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1551 * Added support to the server to enforce that commands are not
1552 executed more than once in 2 seconds. If server receives
1553 commands from client more frequently, timeout is registered
1554 to process the commands. Affected file silcd/command.c.
1555 Added new function silc_server_command_process_timeout.
1557 * Changed NICK_NOTIFY handling in client library to check that
1558 if the client's nickname was changed, so there is no need to
1559 resolve anything from the server.
1561 * Removed error printing from the WHOIS and IDENTIFY commands.
1562 If error occurs then it is ignored silently in the client library.
1563 The application, however, may map the received error to
1564 human readable error string. The application currently maps
1565 the NO_SUCH_NICKNAME error to string.
1567 * Made the command status message public to the application. Moved
1568 them from lib/silcclient/command_reply.c to
1569 lib/silcclient/command_reply.h. The application can map the
1570 received command status to the string with the
1571 silc_client_command_status_message function.
1573 * Added check to the server to check that client's ID is same
1574 as the Source ID in the packet the client sent. They must
1577 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1579 * Added dist-bzip hook to the Makefile.am to make bzip2
1580 compressed distributions.
1582 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1584 * Server now enforces the maximum length for the nickname and
1585 the channel as protocol specification dictates. 128 bytes for
1586 nickname and 256 bytes for channel name.
1588 * Moved the WHOIS printing to the application. The client libary
1589 does not print out the WHOIS information anymore, the application
1590 must do it. Renamed silc_client_command_reply_whois_print to
1591 the silc_client_command_reply_whois_save.
1593 The client's idle time is also sent to the application now, and
1594 the idle is shown on screen.
1596 * Added silc_client_command_reply_identify_save to save the
1597 received IDENTIFY entries.
1599 * Do not check for channel private keys in message sending and
1600 reception if the channel does not have the PRIVKEY mode set.
1601 Affected file lib/silclient/client_channel.c.
1603 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1605 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1606 just surfaced after chaning the JOIN procedure.
1608 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Added silc_client_get_clients_by_list to get client entries
1611 from Client ID list, that is returned for example by JOIN
1612 and USERS command replies. The application should use this
1613 function for example when JOIN command reply is received to
1614 resolve the clients already on the channel (library does not
1615 do that anymore as USERS command reply is not used in the JOIN
1616 procedure anymore). Affected files lib/silcclient/silcapi.h and
1617 lib/silcclient/idlist.c.
1619 * JOIN command reply and USERS command reply returns now SilcBuffer
1620 pointers instead of unsigned char pointers when returning
1621 the client list and mode list.
1623 * Added <Client ID> argument to the JOIN command reply, mainly
1624 for the server to identify for which client the command was
1625 originally sent. Updated protocol specs accordingly.
1627 * Added SilcDlist private_key pointer to the SilcChannelEntry
1628 in the client to support the channel private keys. Affected
1629 file is lib/silcclient/idlist.h.
1631 * Added SilcChannelPrivateKey argument to the function
1632 silc_client_send_channel_message so that application can choose
1633 to use specific private ke if it wants to. If it is not provided,
1634 the normal channel key is used, unless private keys are set.
1635 In this case the first (key that was added first) is used
1636 as the encryption key.
1638 * Implemented the support for channel private key handling.
1639 Implemented the following functions:
1641 silc_client_add_channel_private_key,
1642 silc_client_del_channel_private_keys,
1643 silc_client_del_channel_private_key,
1644 silc_client_list_channel_private_keys and
1645 silc_client_free_channel_private_keys
1647 Affected file lib/silcclient/client_channel.c.
1649 * Added the support for the private keys in the channel message
1650 sending and encryption and in the message reception and
1651 decryption. Affected funtions are
1652 silc_client_send_channel_message and silc_client_channel_message.
1654 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1656 * Added SKE's key verify callback to the client library's
1657 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1659 * Removed the statement that server (or router) must send USERS
1660 command reply when joining to the channel so that the client
1661 knows who are on the channel. Instead, the client list and
1662 client's mode list is now sent in the JOIN command reply to the
1663 client who joined channel. This is better solution.
1665 * Added function silc_server_get_users_on_channel and function
1666 silc_server_save_users_on_channel to the silcd/server.[ch].
1668 * Removed function silc_server_command_send_users from the
1671 * Do not show topic on the client library anymore. The topic is
1672 sent in the command reply notify to the application and the
1673 application must show the topic now.
1675 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Added client searching by nickname hash into the IDENTIFY and
1678 WHOIS commands in the server as they were clearly missing from
1679 them. Affected file is silcd/command.c.
1681 * Fixed a bug in private message receiving in the client library.
1682 The remote ID was freed and it wasn't supposed, now it is
1685 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1687 * Minor fix to the channel payload; allocate the data area, as it
1688 needs to be of specific length.
1690 * If the key agreement port is zero then the operating
1691 system will define the bound port. Affected files are
1692 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1694 * Added new function silc_channel_payload_decrypt into the file
1695 lib/silccore/silcchannel.[ch].
1697 * Moved the channel message etc, check from silc_packet_decrypt
1698 to applications. The library calls now a generic
1699 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1700 when the packet is either normal or special. This was done to
1701 allow more wide range of checking that was not allowed when
1702 the code was in library. Now applications can do virtually any
1703 checks to the packet and return to the library the decision how
1704 the packet should be processed. Affected files are
1705 lib/silccore/silcpacket.[ch].
1707 Added silc_server_packet_decrypt_check to the server and
1708 silc_client_packet_decrypt_check to the client library.
1710 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1711 to send with specified source and destination information.
1713 * Channel message delivery between routers was broken after the
1714 channel key distribution was fixed earlier. The channel key
1715 was used be to distributed to other routers as well which is not
1716 allowed by the protocol. Now this is fixed and channel keys
1717 really are cell specific and the channel message delivery between
1718 routers comply with the protocol specification.
1720 * Fixed various commands in server to check also the global list
1721 for the channel entry and not just the local list. The affected
1722 file silcd/command.c.
1724 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Added assert()s to buffer formatting and unformatting routines
1727 to assert (if --enable-debug) when error occurs. Affected
1728 file: lib/silcutil/silcbuffmt.c.
1730 * Changed to auto-reconnect to check whether the remote host is
1731 router and register the re-connect timeout if it is. It used
1732 to check that whether we are normal server, but router must do
1733 auto-reconnect with another router as well. Affected file
1736 * Removed the [<key len>] option from CMODE command as the cipher
1737 name decides the key length, nowadays. See the defined ciphers
1738 from the protocol specification.
1740 * Added [<hmac>] option to the CMODE command to define the HMAC
1741 for the channel. Added SILC_CMODE_HMAC channel mode.
1743 * Added [<hmac>] option for the JOIN command so that user can
1744 select which HMAC is used to compute the MACs of the channel
1747 * Added Hmac field to the Channel Message Payload. The integrity
1748 of plaintext channel messages are now protected by computing
1749 MAC of the message and attaching the MAC to the payload. The
1750 MAC is encrypted. Now, it is clear that this causes some
1751 overhead to the size of the packet but rationale for this is that
1752 now the receiver can verify whether the channel message decrypted
1753 correctly and also when private keys are set for the channel the
1754 receiver can decrypt the packet with several keys and check from
1755 the MAC which key decrypted the message correctly.
1757 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1758 lib/silccrypt/silccipher.[ch].
1760 * Added silc_hash_len to return the digest length into the
1761 lib/silcrypt/silchash.[ch].
1763 * Rewrote parts of Silc Channel Payload interface in the
1764 lib/silccore/silcchannel.[ch]. The encode function now also
1765 encrypts the packet and parse function decrypts it.
1767 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1769 * Fixed a minor formatting bug in the SKE's key material processing.
1770 It actually might have processed the keys wrong way resulting
1773 * Redefined the mandatory HMAC algorithms and added new algorithms.
1774 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1775 and hmac-md5 truncated to 96 bits. The mandatory is now
1776 hmac-sha1-96. Rest are optional (including the one that used
1777 to be mandatory). Rationale for this is that the truncated HMAC
1778 length is sufficient from security point of view and can actually
1779 make the attack against the HMAC harder. Also, the truncated
1780 HMAC causes less overhead to the packets. See the RFC2104 for
1783 * Added new [hmac] configuration section. The SKE used to use
1784 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1785 is of course wrong. The official names that must be proposed in
1786 the SKE are the ones defined in the protocol specification
1787 (hmac-sha1-96 for example). The user can configure any hmac
1788 using any hash function configured in the [hash] section. At
1789 least, the mandatory must be configured.
1791 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1793 * Added HMAC list to the SKE proposal list. It has now both
1794 hash algorithm list and HMAC list. This makes the protocol
1795 incompatible with previous versions. The SKE now seems to work
1796 the way it is supposed to work, for the first time actually.
1798 * Defined plain Hash algorithms to the protocol specification.
1801 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1803 * Implemented support for key agreement packets into the server.
1804 Added functions silc_server_key_agreement and
1805 silc_server_send_key_agreement. Other than these functions,
1806 server has nothing to do with this packet.
1808 * Added support for private message key packets into the server.
1809 Added functions silc_server_private_message_key and
1810 silc_server_send_private_message_key.
1814 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1815 called in the protocol's final callback instead in the END
1816 protocol state. This makes a little more sense and in the same
1817 time in client we can use the same protocol routines for normal
1818 key exchange and to key agreement packet handling as well.
1820 * Added to both client's and server's KE protocol context the
1821 SilcSKEKeyMaterial pointer to save the key material. We will
1822 bring the key material to the protocol's final callback by doing
1823 this. The final callback must free the key material.
1825 * Added SKE's packet_send callback into client's KE protocol
1826 context so that the caller can choose what packet sending function
1827 is used. This way we can use different packet sending when
1828 doing normal SKE when doing key agreement packet handling (in
1829 the key agreement packet handling we do not want to encrypt
1832 * Implemented the responder side of the key agreement routines
1833 in the client. The client can now bind to specified port and
1834 accept incoming key negotiation. The key material is passed
1835 to the application after the protocol is over.
1837 * Implemented the processing of incoming Key Agreement packet
1838 in the client. Added function silc_client_key_agreement to
1841 * Implemented the intiator side of the key agreement routines
1842 in the client. The client can now initiate key agreement with
1843 another remote client. The key material is passed to the
1844 application after the protocol is over.
1846 * Created client_keyagr.c to include all the key agreement
1849 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1850 SILC_TASK_CALLBACK except that it is not static.
1852 * Created client_notify.c and moved the Notify packet handling
1853 from the client.[ch] into that file.
1855 * Created client_prvmsg.c and moved all private message and
1856 private message key routines from the client.[ch] into that file.
1858 * Create client_channel.c and moved all channel message and
1859 channel private key routines from the client.[ch] into that file.
1861 * Changed silc_client_get_client_by_id_resolve to resolve with
1862 WHOIS command instead of IDENTIFY command, in the file
1863 lib/silclient/idlist.c.
1865 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1867 * Implemented the SKE's responder side to the Client library.
1869 * When FAILURE is received to the protocol do not trust it
1870 blindly. Register a timeout to wait whether the remote closes
1871 the connection as it should do it, only after that process the
1872 actual failure. This was changed to both client and server.
1874 * Added client_internal.h to include some of the structures
1875 there instead of client.h in lib/silcclient/.
1877 * Added function silc_task_unregister_by_callback to unregister
1878 timeouts by the callback function.
1880 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1882 * Some "Incomplete WHOIS info" errors has been appearing on the
1883 log files. Took away the entry->userinfo check from WHOIS
1884 reply sending. The entry->userinfo is now " " if client did not
1885 provide one. I thought this was fixed earlier but something
1886 is wrong still. Let's see if the error still appears.
1888 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Fixed a minor bug in the login when the channel key is
1891 re-generated in the server. It used to generate the key in
1892 wrong order and thus caused problems in the channel traffic.
1894 * Fixed a minor bug in channel key distsribution after
1895 KICK command. The key was not sent to the router even though
1898 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1900 * Added silc_ske_process_key_material_data as generic routine
1901 to process any key material as the SILC protocol dictates. The
1902 function is used by the actual SKE library but can be used by
1903 applications as well. This relates to the private message keys
1904 and the channel private keys since they must be processed the
1905 same way the normal SILC session keys. The protocol dictates
1906 this. Affected files: lib/silcske/silcske.[ch].
1908 Added also silc_ske_free_key_material to free the
1909 SilcSKEKeyMaterial structure.
1911 * Defined silc_cipher_set_key function to set the key for
1912 cipher without using the object's method function. The affected
1913 files: lib/silccrypt/silccipher.[ch].
1915 * Implemented silc silc_client_add_private_message_key,
1916 silc_client_add_private_message_key_ske,
1917 silc_client_del_private_message_key,
1918 silc_client_list_private_message_keys and
1919 silc_client_free_private_message_keys functions in the
1922 Added functions silc_client_send_private_message_key to send
1923 the Private Message Key payload and silc_client_private_message_key
1924 to handle incoming Private Message Key payload.
1926 * Added Cipher field to the Private Message Key payload to set
1927 the cipher to be used. If ignored, the default cipher defined
1928 in the SILC protocol (aes-256-cbc) is used.
1930 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1932 * Removed lib/silcclient/ops.h file.
1934 Redefined parts of the SILC Client Library API. Created new
1935 file silcapi.h that deprecates the ops.h file and defines the
1936 published Client Library API. Defined also private message key
1937 API and channel private key API into the file.
1939 This is the file that the application must include from the
1940 SILC Client Library. Other files need not be included by
1941 the application anymore.
1943 * Added new key_agreement client operation callback and also
1944 defined the Key Agreement library API for the application.
1946 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1948 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1949 is used by clients to request key negotiation between another
1950 client in the SILC network. If the negotiation is started it
1951 is performed using the SKE protocol. The result of the
1952 negotiation, the secret key material, can be used for example
1953 as private message key.
1955 Implemented the Key Agreement payload into the files
1956 lib/silccore/silauth.[ch].
1958 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Redefined ciphers for the SILC protocol. Added some new ciphers
1961 and defined the key lengths for the algorithms. Changed the
1962 code accordingly. The default key length is now 256 bits.
1964 * Fixed SKE key distribution function silc_ske_process_key_material
1965 when the key length is more than 128 bits. The default key
1966 length in SILC is now 256 bits.
1968 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1969 to indicate unsupported algorithm.
1971 * Renamed rijndael.c to aes.c and all functions as well.
1973 * Fixed a long standing channel key setting bug in client library.
1974 Weird that it has never surfaced before.
1976 * Fixed bug in channel deletion. If the entire channel is removed
1977 then it must also delete the references of the channel entry
1978 from the client's channel list as the client's channel entry and
1979 the channel's client entry share same memory.
1981 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1983 * Implemented CONNECT and SHUTDOWN commands in the client.
1985 * Implemented CLOSE command to the client.
1987 * Added the function silc_idlist_find_server_by_name into the
1988 files silcd/idlist.[ch].
1990 Added the function silc_idlist_find_server_by_conn into the
1991 files silcd/idlist.[ch].
1993 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1995 * DIE command was renamed to SHUTDOWN. Updated the both code
1998 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1999 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2001 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2004 * Added function silc_server_create_connection function to create
2005 connection to remote router. My server implementation actually
2006 does not allow router to connect to normal server (it expects
2007 that normal server always initiates the connection to the router)
2008 so the CONNECT command is only good for connecting to another
2011 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2013 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2014 or some other client was kicked from the channel.
2016 Implemented the handling of the notify type to both client
2019 Implemented silc_server_send_notify_kicked to send the KICKED
2020 notify. It is used to send it to the server's primary router.
2022 * Implemented the KICK command into server and client.
2024 * Added `query' argument to the silc_idlist_get_client function
2025 to indicate whether to query the client from server or not if
2028 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2029 to indicate that the client is not channel founder.
2033 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2035 * Removed the rng context from SilcPacketContext structure and
2036 changed that the packet routine uses the Global RNG API.
2038 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2040 * Added support for quit message that client can "leave" on the
2041 channel when it quits the SILC. It is ditributed inside the
2042 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2044 Added silc_server_free_client_data that will take the
2045 signoff message as argument.
2047 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2049 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2051 * Updated parts of the protocol specification to keep it up
2054 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2056 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2057 payloads in one packet.
2059 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2060 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2061 use now the new List flag.
2063 * Also deprecated the following packet types: REPLACE_ID,
2064 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2066 * Added list support for Notify packet in server.
2068 * Added silc_server_send_notify_channel_change to send the
2069 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2070 the silc_server_send_replace_id.
2072 * Added silc_server_send_notify_nick_change to send the
2073 NICK_CHANGE notify type. Deprecates the function
2074 silc_server_send_replace_id.
2076 * Added silc_server_send_notify_join to send the JOIN notify type.
2077 Deprecates the function silc_server_send_new_channel_user.
2079 * Added silc_server_send_notify_leave to send LEAVE notify type.
2080 Deprecates the function silc_server_send_remove_channel_user.
2082 * Added silc_server_send_notify_cmode and
2083 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2084 types. Deprecates the silc_server_send_set_mode function.
2086 * Added SERVER_SIGNOFF notify type to indicate that server has
2087 quit. This means that all clients on the channel from that
2088 server will drop. This can be also used when netsplit happens.
2090 Deprecated REMOVE_ID packet type since it is not needed anymore
2093 Added silc_server_send_notify_server_signoff to send the
2094 SERVER_SIGNOFF notify type. Deprecates the function
2095 silc_server_send_remove_id.
2097 Added also silc_server_send_notify_signoff to send the
2098 SIGNOFF notify type.
2100 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2101 SILC protocol from this day on. Changed the protocol
2102 specification as well.
2104 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2105 notify type. It is used between routers to notify about
2106 topic changes on a channel.
2108 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2111 * Partly updated the protocol specification to comply with the
2112 changes now made. It is still though a bit outdated.
2114 * The JOIN notify type now takes one extra argument <Channel ID>.
2115 The packet used to be destined to the channel but now the
2116 JOIN type may be sent as list thus it is impossible to
2117 destine it to any specific channel. By adding this argument
2118 it is again possible.
2120 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Added CREDITS file. The CHANGES and CREDITS file will appear
2123 in the distribution as well.
2125 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2128 types in the server's silcd/packet_receive.c.
2130 * Implemented CMODE and CUMODE to work in router environment.
2132 * Fixed minor encoding and decoding buglet from the
2133 lib/silccore/silcmode.c.
2135 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2138 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2140 * Changed all SilcConfigServer* and silc_config_server* to
2141 SilcServerConfig* and silc_server_config*, respectively.
2144 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2146 * Associated the ID (client or server ID) to the Authentication
2147 Payload to avoid any possibility of forging. Updated the
2148 protocol specification and the code accordingly.
2150 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2152 * The RSA key length is now save to the RsaKey context in the
2153 key generation process in lib/silccrypt/rsa.c. The key length
2154 is now used to figure out the maximum size of the block allowed
2155 to be encrypted/signed.
2157 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2158 is equivalent to the silc_mp_mp2bin but does not allocate any
2161 * Changed silc_mp_mp2bin API to take length argument. If it is
2162 non-zero then the buffer is allocated that large. If zero, then
2163 the size is approximated using silc_mp_sizeinbase, which however
2166 * Created Global RNG API which is global RNG that application can
2167 initialize. After initializing, any routine anywhere in the
2168 code (including library) can use RNG without allocating a new
2169 RNG object. This was done to allow this sort of use of the
2170 RNG in code that has no chance to allocate RNG object. All
2171 applications currently allocate this and many routines in the
2172 library use this. Affected file lib/silccrypt/silcrng.[ch].
2174 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2175 it to use the Global RNG API.
2177 * Defined Authentication Payload into protocol specification that
2178 is used during SILC session to authenticate entities. It is
2179 used for example by client to authenticate itself to the server
2180 to obtain server operator privileges.
2182 Implemented this payload into the lib/silccore/silcauth.[ch].
2183 Implemented also routines for public key based authentication
2184 as the new protocol specification dictates.
2186 Moved definitions of different authentication methods from
2187 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2189 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2190 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2191 silc_pkcs_verify_with_hash functions into the file
2192 lib/silccrypt/silcpkcs.[ch].
2194 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2196 * The client entry's userinfo pointer must be always valid.
2197 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2198 will fail since it requires the userinfo. Now, the userinfo
2199 is allocated as "" if actual userinfo does not exist. Actually,
2200 it must exist and it is totally Ok to drop client connections
2201 that does not announce the userinfo. However, we will make
2202 this workaround for now.
2204 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2205 to return the remote port by socket.
2207 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2209 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2210 SILC_SERVER_PENDING_EXEC and added an new macro
2211 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2212 data or when error occurs while processing the pending command.
2214 Added new argument `destructor' into silc_server_command_pending
2215 and to the SilcServerCommandPending object. This destructor is
2216 now called after calling the pending callback or if error occurs
2217 immediately. If error occurs the actual pending callback won't
2218 be called at all - only the destructor. The destructor may be
2219 NULL if destructor is not needed.
2221 All this applies for client library code as well. Similar
2222 changes were made there as well for the pending commands.
2224 In the client, the application must now allocate the
2225 SilcClientCommandContext with the silc_client_command_alloc
2228 * Added reference counter to the SilcServerCommandContext. Added
2229 function silc_server_command_alloc and silc_server_command_dup
2232 Same type of functions added to the client library for the same
2235 * Removed the cmd_ident from IDListData away since it is now
2236 global for all connections. It is the command identifier used
2237 in command sending and with pending commands. The affected file
2240 * Added reference counter to the SilcSocketConnection objecet to
2241 indicate the usage count of the object. The object won't be
2242 freed untill the reference counter hits zero. Currently only
2243 server uses this, and client ignores it. The client must be
2244 set to use this too later. The affected files are
2245 lib/silccore/silcsockconn.[ch]. Added also the function
2246 silc_socket_dup to increase the reference counter.
2248 This was mainly added because it is possible that the socket
2249 is removed underneath of pending command or other async
2250 operation. Now it won't be free'd and proper DISCONNECTING
2251 flags, etc. can be set to avoid sending data to connection that
2252 is not valid anymore.
2254 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2255 the connection. After that it sets SILC_SET_DISCONNECTED.
2256 It is, however, possible that the socket data is not still freed.
2257 The silc_server_packet_process now checks that data is not
2258 read or written to connection that is DISCONNECTED. The socket
2259 get's freed when the reference counter hits zero.
2261 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2263 * Changed the client operation API: channel_message operation's
2264 `sender' is now the client entry of the sender, not the nickname
2265 and the `channel' is the channel entry, not the channel name.
2267 In the private_message operation the `sender' is now also the
2268 client entry of the sender not the nickname.
2270 Affected file is lib/silcclient/ops.h and all applications
2271 using the client operations.
2273 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2275 * Moved the calling of ops->connect() from connect_to_server_final
2276 into receive_new_id functin since that is the point when the
2277 client is actually allowed to send traffic to network. The
2278 affected file is lib/silcclient/client.c.
2280 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2283 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2284 (if needs broadcasting) instead of broadcasting the packets one
2285 by one which would make a burst in the network traffic.
2287 * Added `broadcast' argument to the functions in silcd/server.[ch]
2288 silc_server_create_new_channel[_with_id] to indicate whether
2289 to send New Channel packet to primary router.
2291 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2293 * Added new function into the silcd/server.[ch] files:
2294 silc_server_create_new_channel_with_id to create new channel with
2295 already existing Channel ID.
2297 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2298 lib/silccore/silcpacket.h. This packet is used t send list of
2299 Set Mode payloads inside one packet. Server uses this to set
2300 the modes for the channels and clients on those channels, that it
2301 announced to the router when it connected to it. The protocol
2302 specification has been updated accordingly.
2304 * The silc_server_new_channel did not handle the packet coming
2305 from normal server as it normally does not send that. However,
2306 when it announces its channels it does send it. Implemented
2307 the support for that.
2309 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2310 into the file lib/silccore/id.h.
2312 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2314 * Fixed memory leaks in the functions silc_idlist_del_client,
2315 silc_idlist_del_channel and silc_idlist_del_server in the file
2316 silcd/idlist.c. All of those leaked like a sieve.
2318 * Fixed some small memory leaks in the client's function
2319 silc_client_notify_by_server.
2321 * Added functions into silcd/server.c: silc_server_announce_clients,
2322 silc_server_announce_channels and silc_server_announce_server.
2323 These functions are used by normal and router server to announce
2324 to its primary router about clients, channels and servers (when
2325 router) that we own. This is done after we've connected to the
2328 These functions effectively implements the following packet types:
2329 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2330 and SILC_PACKET_NEW_ID_LIST.
2332 * Added new functions into the silcd/packet_receive.[ch]:
2333 silc_server_new_id_list, silc_server_new_channel_list and
2334 silc_server_new_channel_user_list to handle the incoming
2335 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2337 * Added support of changing Channel ID in the function
2338 silc_server_replace_id. If the server that announces a channel
2339 to the router already exists in the router (with same name but
2340 with different Channel ID), router is responsible to send
2341 Replace ID packet to the server and force the server to change
2342 the Channel ID to the one router has.
2344 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2345 client that the Channel ID has been changed by the router. The
2346 normal server sends this to the client. Client must start using
2347 the new Channel ID as the channel's ID.
2349 Implemented handling of this new type into lib/silcclient/client.c
2350 into the function silc_client_notify_by_server.
2352 * Added new function silc_idlist_replace_channel_id into the files
2353 silcd/idlist.[ch] to replace the Channel ID.
2355 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2357 * Call silc_server_command_identify_check always when processing
2358 the IDENTIFY command in silcd/command.c
2360 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2362 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2363 send keepalive packets. The packet can be sent by clients,
2364 servers and routers.
2366 Added function silc_socket_set_heartbeat into the file
2367 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2368 If not set, the heartbeat is not performed. The actual
2369 heartbeat is implemented in the low level socket connection
2370 library. However, application is responsible of actually
2373 Added silc_server_send_heartbeat to send the actual heartbeat
2374 packet into silcd/packet_send.[ch]. Server now performs
2375 keepalive with all connections.
2377 * Added silc_task_get_first function into lib/silcutil/silctask.c
2378 to return the timeout task with shortest timeout. There was a bug
2379 in task unregistration that caused problems. TODO has been
2380 updated to include that task system must be rewritten.
2382 * The client library will now resolve the client information when
2383 receiving JOIN notify from server for client that we know but
2384 have incomplete information.
2386 * Rewrote parts of silc_server_remove_from_channels and
2387 silc_server_remove_from_one_channel as they did not remove the
2388 channel in some circumstances even though they should've.
2390 * Encryption problem encountered in server:
2392 The LEAVE command used to send the Channel Key packet to the
2393 router immediately after generating it. However, the code
2394 had earlier sent Remove Channel user packet but not immediately,
2395 ie. it was put to queue. The order of packets in the router
2396 was that Channel Key packet was first and Remove Channel User
2397 packet was second, even though they were encrypted in the
2398 reverse order. For this reason, MAC check failed. Now, this
2399 is fixed by not sending the Channel Key packet immediately but
2400 putting it to queue. However, this is more fundamental problem:
2401 packets that are in queue should actually not be encrypted
2402 because packets that are sent immediately gets encrypted
2403 actually with wrong IV (and thus MAC check fails). So, packets
2404 that are in queue should be encrypted when they are sent to
2405 the wire and not when they put to the queue.
2407 However, the problem is that the current system has not been
2408 designed to work that way. Instead, the packet is encrypted
2409 as soon as possible and left to the queue. The queue is then
2410 just purged into wire. There won't be any fixes for this
2411 any time soon. So, the current semantic for packet sending
2414 o If you send packet to remote host and do not force the send
2415 (the packet will be in queue) then all subsequent packets to the
2416 same remote host must also be put to the queue. Only after the
2417 queue has been purged is it safe again to force the packet
2420 o If you send all packets immediately then it safe to send
2421 any of subsequent packets through the queue, however, after
2422 the first packet is put to queue then any subsequent packets
2423 must also be put to the queue.
2425 Follow these rules and everything works fine.
2427 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2429 * Added new function silc_server_remove_clients_by_server to
2430 remove all client entries from ID list when the server connection
2431 is lost. In this case it is also important to invalidate all
2432 client entires as they hold the invalid server entry. This
2433 fixes fatal bug when server has lost connection and will reconnect
2436 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2438 * Made some sanity checks to silc_server_daemonise like to check
2439 whether the requested user and group actually exists.
2441 * Added sanity check to SKE's silc_ske_responder_finish to check
2442 that the public and private key actually is valid.
2444 * Invalidate the client's nickname when receiving Replace ID
2445 packet and the Client ID is being replaced. This means that the
2446 server will query the nickname if someone needs it (client)
2449 * Sort the ID Cache in client library when the ID Cache data
2450 has changed (needs sorting).
2452 * Do not allow for SILC client to create several connections to
2453 several servers. The client does not support windows right now
2454 and generating multiple connections causes weird behaviour.
2456 Irssi-silc client does support windows and can handle several
2457 connections without problems, see: www.irssi.org and SILC plugin.
2459 * Fixed some places where client was added to the IDList. The
2460 rule of thumb is following (in order to get everything right):
2461 If the client is directly connected local client then the
2462 `connection' argument must be set and `router' argument must be
2463 NULL to silc_idlist_add_client function. If the client is not
2464 directly connected client then the `router' argument must
2465 bet set and the `connection' argument must be NULL to the
2466 silc_idlist_add_client function.
2468 * The funtion silc_server_packet_send_local_channel actually did
2469 not check whether the client was locally connected or not. It
2470 does that now. Fixed a bug related to LEAVE command.
2472 * Fixed Remove Channel User payload parsing bug in server's
2473 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2475 * The server's silc_server_save_channel_key now checks also the
2476 global ID list for the channel as it might not be in the local
2477 list. Fixed a bug related to LEAVE command.
2479 * Is this the end of the [<unknown>] buglet that has been lurking
2480 around for a long time? A little for loop fix in server's
2481 silc_server_command_whois_parse that is used by both IDENTIFY
2482 and WHOIS command. At least, this was a clear bug and a cause
2483 of one type of [<unknown>] buglet.
2485 * WHOIS and IDENTIFY commands call the function
2486 silc_server_command_[whois/identify]_check function even if
2487 we are not router server.
2489 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Added --with-gmp configuration option. If set the GMP
2492 is always compiled in the SILC source tree. If not set then
2493 it is checked whether the system has the GMP3 installed. If
2494 it has then the GMP won't be compiled (the system's headers
2495 and library is used), if it doesn't have it then the GMP is
2496 compiled in the SILC source tree.
2498 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2500 * Changed RSA private exponent generation to what PKCS #1
2501 suggests. We try to find the smallest possible d by doing
2502 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2503 not security fix but optimization.
2505 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2507 * Added new config entry [Identity] to fork the server and run
2508 it as specific user and group. A patch from Bostik.
2510 * Imported Dotconf configuration library into lib/dotconf.
2511 This will be used to create the SILC configuration files later.
2512 It will appear in the distsribution after this commit.
2514 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2516 * A big code auditing weekend happening. Auditing code for
2517 obvious mistakes, bugs and errors. Also, removing any code
2520 Removed files for being obsolete:
2522 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2523 inline in the file lib/silcutil/silcbuffer.h)
2525 o lib/silcutil/silcbufutil.c (the header has inline versions)
2527 Changed code to fix possible error conditions:
2529 o The buffer formatting routines now check that the destination
2530 buffer really has enough space to add the data. This applies for
2531 both buffer formatting and unformatting
2532 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2533 unformatting was changed to accomodate following rules:
2534 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2535 sent to the function while XXX_*STRING will not allocate or copy
2536 the data into the buffer. Instead it sets the pointer from the
2537 buffer into the pointer sent as argument (XXX_*STRING used to
2538 require that the pointer must be allocated already). This change
2539 makes this whole thing a bit more consistent and more optimized
2540 (note that the data returned in the unformatting with XXX_*STRING
2541 must not be freed now). The routines return now -1 on error.
2543 o Tried to find all code that use buffer_format and buffer_unformat
2544 and added return value checking to prevent formatting and
2545 especially unformatting errors and possible subsequent fatal
2548 o Changed ske->x and ske->KEY to mallocated pointers in
2549 lib/silcske/silcske.h. Fixed possible data and memory leak.
2551 o Added return value checking to all *_parse* functions. Fixed
2552 many memory leaks as well.
2554 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2555 so that buffer overflows would not happen. All code now also
2556 checks the return value as it can fail.
2558 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2560 * Added reconnection support to server if the normal server looses
2561 its connection to the router (for example if router is rebooted).
2562 The server performs normal reconnection strategy implemented
2563 to the server. Affected file silcd/server.c.
2565 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2567 * Added new packet type SILC_PACKET_SET_MODE that is used to
2568 distribute the information about changed modes (for clients,
2569 channels and clients channel modes) to all routers in the
2570 network. Updated the protocol specification accordingly.
2572 Added functions into silcd/packet_send.c and
2573 silcd/packet_receive.c: silc_server_send_set_mode,
2574 silc_server_set_mode.
2576 Added new files silcmode.[ch] into lib/silccore that implements
2577 the encoding and decoding of Set Mode Payload. Added new type
2578 SilcSetModePayload. Moved the definitions of different modes
2579 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2581 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Oops, a little mistake in server's connection authentication
2584 protocol. The protocol is not ended with FAILURE but with
2585 SUCCESS if the authentication is Ok. :) Affected file is
2588 * Implemented NICK_CHANGE notify handling in server in the file
2589 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2590 the local clients on the channel. After the changing nickname
2591 in router environment snhould work and the [<unknown>] nickname
2592 should appear no more.
2594 The silc_server_replace_id function that receives the Replace ID
2595 payload now sends the NICK_CHANGE notify type also in the file
2596 silcd/packet_receive.c
2598 * Changed WHOIS and IDENTIFY command to support the maximum amount
2599 of arguments defined in protocol specs (3328 arguments). This
2600 fixed a bug that caused problems when there were more than three
2603 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * Added extra parameter, command identifier, to the
2606 silc_client_send_command so that explicit command identifier
2609 Changed that ID list routines uses specific command identifier
2610 when sending WHOIS/IDENTIFY requests to the server so that they
2611 can be identified when the reply comes back.
2613 Affected files lib/silcclient/command.[ch],
2614 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2616 * Added `sender' argument to silc_server_packet_send_to_channel
2617 to indicaet the sender who originally sent the packet to us
2618 that we are now re-sending. Ignored if NULL. Affected file
2619 silcd/packet_send.[ch].
2621 * Added some server statistics support in silcd/server_internal.h
2622 SilcServerStatistics structure and around the server code. Also
2623 send some nice statistics information when client is connecting
2626 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2628 * Fixed channel ID decoding in server's JOIN command reply in
2629 silcd/command_reply.c
2631 * Fixed braodcasting of replace ID payload to not to send it if
2632 we are standalone server in silcd/packet_receive.c.
2634 * Fixed all channel message sending routines to not to send
2635 packets to clients that has router set, since they are routed
2636 separately in the same function earlier. Affects file
2637 silcd/packet_send.c and all channel packet sending functions.
2639 * In USERS reply, res_argv[i] are not allocated, the table
2640 is allocated. Thus changed that free the table, not its
2643 * In server's whois_check and identify_check if the client is
2644 locally connected do not send any WHOIS commands - they are not
2647 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2649 * Fixed some minor bugs in client when sending WHOIS command. The
2650 arguments was in wrong order.
2652 * Removed statis function add_to_channel from server in
2653 silcd/command.c that was previously used with the joining but
2656 * Tested USERS command in router environment successfully with two
2657 routers, two servers and two clients.
2659 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Reorganized the USERS command and command reply in client library
2662 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2663 When the command is given by user we register a pending command
2664 callback that will reprocess the command after the reply has been
2665 received from the server. When reprocessing the packet we then
2666 display the information. Thus, the USERS information is displayed
2667 now in the command callback instead of in the command reply
2668 callback. The processing of the command is same as previously
2669 when server has sent the command reply in the JOINing process.
2671 * Added to USERS command in silcd/command_reply.c to join the client,
2672 we didn't use to know about, to the channel after we've created
2673 a client entry for it. Also, for clienet we did know already still
2674 check whether it is on the channel or not and add it if not.
2676 * Removed silc_server_command_join_notify as the function and its
2679 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Changed the client's pending command handling to the same as the
2682 server's pending command handling. It is also now possible to
2683 execute command reply functions from other command reply
2684 function as the function callbacks for commands and command
2685 replies are one and same. The pending commands are not static
2686 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2687 in client connection context. Thus, pending commands are server
2688 connection specific as it is convenient.
2690 Changed the function silc_client_command_pending and
2691 silc_client_command_pending_del and added new function
2692 silc_client_command_pending_check. Removed the
2693 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2696 * Added cmd_ident, current command identifier, to the client
2697 connection context in lib/silcclient/client.h to keep track on
2698 command identifiers used in command sending. Client's command reply
2699 function handling now supports the mandatory command identifiers.
2701 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2702 funtions in client to fully support pending command callbacks.
2704 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2705 as one of the arguments to the application in the command reply
2708 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2709 before first releasing SILC but came back. Now it is removed again
2710 and should come back nomore. The FORWARDED flag was used only
2711 by the JOINing procedure by forwarding the command packet to router.
2712 Now, the JOINing procedure has been changed to more generic (due
2713 to various router environment issues) and FORWARDED is not needed
2714 anymore for anything. The protocol specification is yet to be
2717 Now, removed silc_server_packet_forward from server and the flag
2718 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2720 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2722 * Renamed NAMES command to USERS command. The NAMES was named that
2723 due to historical reasons. Now it is renamed. Also, rewrote
2724 parts of the USERS command. The nickname list is not sent anymore
2725 by the server. Only Client ID and mode lists are sent in the USERS
2726 command. Changed this also to the protocol specification.
2728 The client now resolves the names and stuff after it receives
2729 the USERS list from the server when joining to the channel.
2731 * WHOIS and IDENTIFY commands has been changed to support multiple
2732 Client ID's per command. One can now search for multiple users
2733 in the network by sending only one WHOIS or IDENTIFY command.
2734 Changed the code and the protocol specifications.
2736 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2737 uses silc_server_command_whois_parse to parse the request. */
2739 * If normal server, do not parse the WHOIS and IDENTIFY requests
2740 before sending it to the router. Saves some time.
2742 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * Fixed JOIN command on client library. Wrong number of arguments
2745 used to crash the client.
2747 * Added silc_server_channel_has_global function to check whether
2748 channel has global users or not.
2750 * Added silc_server_channel_has_local function to check whether channel
2751 has locally connected clients on the channel.
2753 * The silc_server_remove_from_one_channel now checks whether the
2754 channel has global users or not after given client was removed from
2755 the channel. It also checks whether the channel has local clients
2756 on the channel anymore. If it does not have then the channel entry
2757 is removed as it is not needed anymore.
2759 * The silc_server_notify now checks on JOIN notify whether the joining
2760 client is one of locally connected or global. If it is global then
2761 the channel has now global users on the channel and that is marked
2762 to the channel entry. Also, it now saves the global client to
2763 global list who is joining and JOINs it to the channel. This is
2764 for normal server, that is.
2766 Changed silc_server_send_notify_on_channel,
2767 silc_server_packet_relay_to_channel and
2768 silc_server_packet_send_to_channel check if we are normal server
2769 and client has router set (ie. global client) do not send the
2770 message to that client, as it is already routed to our router.
2772 * Implemented LEAVE notify type handling in silc_server_notify
2775 * Tested LEAVE command in router environment successfully. Tested
2776 with two routers, two servers and two clients.
2780 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2782 * Implemented SIGNOFF notify type handling in silc_server_notify
2785 * silc_server_remove_id now removes the client entry from all channels
2786 it has joined and thusly sends SIGNOFF notify type.
2788 * Rewrote the NAMES list generation in server by removing two excess
2789 loops. The lists are created now inside one loop.
2791 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * silc_server_remove_channel_user checks now also global list
2794 for channel and client.
2796 * silc_server_new_channel_user checks now both local and global
2797 list for channel and client. Fixed a bug in client id decoding.
2798 Used to decode wrong buffer.
2800 * silc_server_channel_message checks now both local and global
2801 list for channel entry.
2803 * Tested channel joining (hence JOIN) in router environment
2804 successfully. Tested with two routers, two servers and two
2807 * Tested channel message sending in router environment successfully.
2809 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Added silc_server_save_channel_key into server.[ch] to save the
2812 received channel key in Channel Key payload processing. It is
2813 also used in JOIN command reply handling.
2815 Equivalent function silc_client_save_channel_key added into
2816 client.[ch] into client library.
2818 * Changed JOIN command reply to send information whether the channel
2819 was created or not (is existing already) and the channel key
2820 payload. Changed protocol specs accordingly.
2822 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2823 the request was sent by ID and not by nickname. Crashed on
2826 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2828 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2829 now correctly save the received data.
2831 * silc_server_free_sock_user_data now notifies routers in the
2832 network about entities leaving the network.
2834 At the same time implemented functions silc_server_remove_id
2835 and silc_server_send_remove_id to receive and send REMOVE_ID
2836 packets. The packet is used to notify routers in the network
2837 about leaving entities. The ID removed will become invalid in
2840 * Added function silc_idlist_del_server into server. Removes and
2841 free's server entry from ID list.
2843 * silc_server_private_message function now checks, if we are router,
2844 that the destination ID really is valid ID, naturally.
2846 * In router when NEW_ID packet is received (for new client) the
2847 hash of the Client ID is saved in the ID Cache but the
2848 client->nickname is set to NULL, instead of putting the hash
2851 IDENTIFY command now also checks that client->nickname must be
2852 valid. If it is not if will request the data from the server who
2853 owns the client. Added new function
2854 silc_server_command_identify_check.
2856 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2857 to set the command to already allocated Command Payload.
2859 * Tested private message sending in router environment with two
2860 routers, two servers and two clients. Fixed minor bugs and now
2863 * Fixed segfault from client's NAMES command. Used to crash if
2866 * Forwarded packets must not be routed even if it is not destined
2867 to the receiver. Changed server code comply with this.
2869 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2871 * Added `require_reverse_mapping' boolean value to ServerParams
2872 structure. If TRUE (not default) the server will require that
2873 the connecting host has fully qualified domain name.
2875 If the reverse mapping is not required and hostname could not be
2876 found the IP address is used as hostname.
2878 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2880 * Implemented version string checking to both client and server.
2881 The check is incomplete currently due to the abnormal version
2882 strings used in development version of SILC.
2884 * Changed all command functions in server to use the new
2887 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2889 * Changed char *data to unsigned char *data in ID Cache system to
2890 support binary data as ID Cache data. Changed code to support
2891 binary data in lib/silccore/idcache.c.
2893 * Renamed silc_server_packet_relay_command_reply to
2894 silc_server_command_reply as it is normal packet receiving
2895 function. Rewrote the function to accept command replys for
2896 servers and not only for clients.
2898 * Mark remote router always as registered server if we are connecting
2899 to it. Otherwise, commands sent by the router to us are ignored.
2901 * All ID List find routines now returns the ID Cache Entry pointer
2902 as well if requested.
2904 * WHOIS command works now in router environment, tested with two
2905 routers, two servers and two clients.
2907 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2908 in router environment (as it is almost equivalent to WHOIS) but
2909 hasn't been tested thoroughly. Added new functions:
2911 silc_server_command_identify_parse
2912 silc_server_command_identify_send_reply
2913 silc_server_command_identify_from_client
2914 silc_server_command_identify_from_server
2916 * Disabled route cache adding because adding two different ID's with
2917 same IP replaces the old cache entry thus giving wrong route.
2918 The entry->router->connection is always the fastest route anyway
2919 so route cache may not be needed. Of course, new routes maybe
2920 established after receiving the ID when the entry->router->connection
2921 might not be anymore the most optimal.
2923 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Add route cache for received ID for fast routing.
2927 * Added silc_server_packet_route to route received packet on router
2928 that is not destined to us.
2930 * Renamed silc_server_get_route to silc_server_route_get.
2932 * Added id_string and id_string_len fields into SilcServer to
2933 include encoded ServerID for fast comparing without excess
2934 encoding of the ID's.
2936 * Cleaned up WHOIS command on server side. Added following static
2939 silc_server_command_whois_parse
2940 silc_server_command_whois_check
2941 silc_server_command_whois_send_reply
2942 silc_server_command_whois_from_client
2943 silc_server_command_whois_from_server
2945 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2946 arguments in command replies. All command functions should be
2947 updated to use this macro.
2949 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Minor typo fixes on command reply handling on server.
2953 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2955 * Added silc_server_command_add_to_channel internal routine to add
2956 the client to the channel after router has created the channel and
2957 sent command reply to the server.
2959 * Added generic silc_server_send_command to send any command from
2962 * Use static buffer with ID rendering instead of duplicating data.
2964 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2966 * Fixed a channel user mode bug when joining to a channel server gave
2967 everybody channel founder rights, oops.
2969 * We mark ourselves as the router of the incoming server connection
2970 if we are router ourselves. This way we can check in some packet
2971 sending functions whether it is locally connected server. For
2972 incoming router connections we put NULL.
2974 * For router sending packets locally means now always sending the
2975 packet cell wide; to local clients and local servers. For normal
2976 server sending packet locally means sending it to only local
2979 * Fixed the JOIN command to really work in router environment. If the
2980 channel is created it is always created by the router. Router is
2981 also responsible of making the initial joining to the channel,
2982 sending JOIN notify to the sending server and distributing
2983 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2984 does not exist server doesn't do anything else but forward the
2985 command to the router which performs everything.
2987 * Added silc_server_send_channel_key function to send the Channel Key
2990 * Added silc_server_create_channel_key to create new channel key. The
2991 channel key is now re-generated everytime someone joins or leaves
2992 a channel, as protocol dictates. Note: channel->key_len is the
2995 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2997 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2998 packet_receive.[ch] to separate packet sending and receiving
2999 routines. The server.[ch] now includes everything else including
3000 actual packet processing (writing and reading data) and other
3003 Renamed silc_server_private_message_send_internal to
3004 silc_server_send_private_message. The routine is still though
3005 used only to relay private messages as server does not send
3006 private messages itself.
3008 Renamed silc_server_new_channel to silc_server_create_new_channel
3009 and added new function sicl_server_new_channel that handles the
3010 incoming New Channel packet. Added also new sending function
3011 silc_server_send_new_channel to send New Channel Payload.
3013 * Added new function silc_server_notify to process incoming notify
3014 packet to the server/router. Server may then relay the notify
3015 to clients if needed.
3017 * Added new function silc_server_new_channel_user to process incoming
3018 New Channel User packet. Router will redistribute the packet and
3019 send JOIN notify to its local clients and locally connected servers
3020 if needed. Normal server will send JOIN notify to its local client
3021 on same channel when received this packet. Added also corresponding
3022 sending function silc_server_send_new_channel_user to sent the
3025 * Added boolean route argument to send_notif_to_channel and
3026 packet_send_to_channel functions to attempt to route the packet
3027 if it is TRUE and send only locally if it is FALSE.
3029 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * silc_server_replace_id now broadcasts the received replace ID
3032 packet if it is not broadcast packet already. The router must
3033 broadcast to inform other routers about changed ID.
3035 * Added backpointer to server's router into SilcServer context in
3036 silcd/server_internal.h.
3038 * Fixed silc_server_packet_broadcast to send correct broadcast
3041 * The channel key is now distributed to the local client as soon
3042 as it is received from the router (in router environment) so that
3043 no other packet may be sent for the channel until client has
3046 * silc_server_remove_channel_user now broadcasts the received
3047 Remove Channel User packet if it is not broadcast packet already.
3048 The router must broadcast to inform other routers about removed
3051 * Added users field into SilcPacketContext that is a reference count
3052 of the context. One can increase the reference count by calling
3053 silc_packet_context_dup which is now changed to just increase the
3054 reference count instead of duplicating the data. The reference
3055 count is decresed by calling silc_packet_context_free that will
3056 free the data after the reference count hits zero.
3058 For now on the packet context and everything allocated into it
3059 (including the raw packet from network) must be freed by calling
3060 the new silc_packet_context_free function. Added also new function
3061 silc_packet_context_alloc that must be used now to allocate the
3062 context. This also means that if a routine is asynchronous from
3063 silc_[client/server]_packet_parse_type the packet context must
3064 be duplicated by calling silc_packet_context_dup. Otherwise it
3065 gets free'd after silc_[client/server]_packet_parse_type returns.
3066 Also, one must remember that if packet is duplicated then its
3067 reference count must be decresed by calling the free function as
3068 many times as it was duplicated.
3070 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3071 from both client and server.
3073 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Made joining to a channel working in router environment.
3077 * Cleaned up JOIN command on server side and create function
3078 silc_server_command_join_channel internal routine to make the
3081 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Changed silc_command_pending list to SilcDList. Also, added
3084 `ident' field to SilcServerCommandPending structure to identify
3085 the reply and to call correct callback.
3087 Added silc_server_command_pending_check function to replace the
3088 corresnponding macro. The silc_command_pending list is not
3091 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3092 to set identifier to previously allocated Command Payload. It
3093 is used to set identifier for command when resending Command
3096 * Added silc_command_payload_encode_payload to encode Command
3097 Payload buffer from SilcCommandPayload structure.
3099 * Added silc_argument_payload_encode_payload to encode Argument
3100 payload buffer from SilcArgumentPayload structure.
3102 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Changed WHOIS command to support router connection on server side.
3105 The whois request is always sent to router unless the server is
3106 standalone server. After server has received the reply from the
3107 router will it send the reply to the client.
3109 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3110 broadcast received broadcast packet. The function is used only
3111 by router. The broadcast packet is always sent to the router's
3114 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3115 render given ID to printable string, for log files for example.
3117 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Made basic router to router connections working. At least they
3120 can now connect to each other but nothing really works the way
3121 they are supposed - yet.
3123 * Added new initiator token to RouterConnection configuration
3124 file in silcd/serverconfig.[ch]. It is used to tell whether we
3125 are the initiator to the remote router or whether we'll expect
3126 the other end to connect.
3128 * Moved registering of listener task to silc_server_init, hence
3129 the server starts listenning as soon as it is run, even if it
3130 does not have connections to other routers. Let's see how well
3133 * Changed default connection retry timeouts for more suitable in
3136 * Removed cipher and such arguments from silc_idlist_add_client
3137 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3138 Added new function silc_idlist_add_data to add the keys and stuff
3141 * Added SilcIDListData structure and added it to SilcClientEntry
3142 and SilcServerEntry as their first field in the structure. This
3143 way we can explicitly cast the ID entries to the SilcIDListData
3144 structure and get common data for the entries. In past, we had
3145 to first check what type of connection it is and then cast it to
3146 correct ID entry type. Now, we can directly cast the opaque
3147 pointer to the SilcIDListData (no matter what ID entry it actually
3148 is) and get the data needed.
3150 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3153 in some circumstances even if threre were timeout tasks, though not
3154 IO tasks, but tasks anyway. Now fixed.
3156 * Defined SilcServerConnection structure to hold connection specific
3157 stuff about directly connected servers and routers. The definition
3158 is currently in silcd/server_internal.h. I thought about having
3159 a bit more important role fro this struct but for now it is used
3160 only when connecting to other server (or router actually).
3162 * Added connecting retry support in server when connecting to
3163 router(s). The retry feature implement exponential backoff
3164 algorithm. Also, added SilcServerParams structure to hold default
3165 parameters for server. For now, it include these retry settings
3166 and are hard coded. After server is moded to be as Silc Server
3167 Library this structure will be more important.
3169 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Changed client librarys channel->clients table to SilcList and
3172 changed code accordingly.
3174 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Changed client's channel table to SilcList and changed code
3177 accordingly. Also changed SilcChannelClientEntry to include back-
3178 pointer to the channel so that client entry can use that structure
3179 as list as well and we have fast cross-reference to the channel.
3180 This change dramatically decreased the complexity of channel
3181 handling with client entry and vice versa (removed one extra
3182 loop when searching for channel entry from many functions).
3184 * Changed server->sim from table to SilcDList and changed code
3187 * NAMES command can now be used from user interface. It will show
3188 the user list on the channel, neatly.
3190 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3191 Code now saves realname of the user if it becomes available.
3193 * Renamed configure.in to configure.in.pre and made ./prepare
3194 script to automatically add correct version string to
3195 configure.in which it creates from configure.in.pre.
3197 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * NAMES command reply now shows users mode with the nickname when
3202 * Moved silc_client_ch[u]mode[_char] functions from
3203 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3204 place sucks, they are utility functions and should be in some
3207 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3209 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3212 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3216 * Added TRQ (efficient deque and list library) into lib/trq. This is
3217 a very good list library that is currently used in the SILC. Defined
3218 SilcList API over the library because I didn't like the API very
3219 much. See lib/trq/silclist.h for the API and examples of how to
3220 use the API. Fixed various places in the code to use the new
3221 SilcList API. The SilcList is meant for lists that has a structure
3222 already defined as a list. It is not suitable to add just some
3223 context to the list (in TRQ, the context is the list actually).
3225 So, I defined SilcDList that can be used for the purpose where
3226 predefined list structure does not exit. This can be used as
3227 such list. Now some context just can be added to the SilcDList.
3228 Currently this list is not used in the SILC just yet, though there
3229 are a lot places where this can replace dynamically allocated
3230 tables and I will fix these places, later, to use SilcDList.
3231 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3232 and use TRQ internally).
3234 Also fixed some annoying warning messages that the original TRQ
3235 code generated. Also minor changes to TRQ's Makefile.in.
3237 * Added support for querying by Client ID to both WHOIS and
3238 IDENTIFY commands into server, as required by the protocol.
3240 * Removed method function pointers from SilcBuffer structure. They
3241 weren't used to anything and just increased the context size for
3242 no good reason. This change also made silc_buffer_alloc and
3243 silc_buffer_free functions inline functions.
3245 * Disabled command flooding detection support until it's fixed so
3246 that it accepts commands in but does not execute them more than once
3249 * Added silc_net_localhost(), to return local hostname, into
3250 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3251 that must be initialized before calling silc_client_init.
3253 * Added new function: silc_server_send_notify_on_channels to send
3254 notify messages to all channels client has joined. It is assured
3255 that the message is sent only once per client.
3257 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3258 lib/silcutil/silcutil.[ch] as silc_format function. The new
3259 function is generic and is used by server as well, not only by
3260 the logging routines.
3262 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3263 the provided version string was not acceptable. Added new function:
3264 silc_ske_check_version into lib/silcske/silcske.h. The function
3265 must be implemented by the application (client or server) and it
3266 does not reside in the SKE library. The function checks the version
3267 string remote end sent.
3269 * Added back pointers (to opaque context and to SilcSocketConnection)
3270 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3272 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3273 duplicate packet context structure.
3275 * Changed `notify' client operation to send same arguments as client
3276 receives from server except for ID's. ID's are mapped to correct
3277 ID entry and that is returned. Also, if channel entry is not sent
3278 by server but the notify is for channel the channel entry is sent
3279 to application (otherwise application doesn't know that it is for
3280 channel (library gets it from packet's Destination ID)).
3282 * Added silc_client_remove_from_channels into client library to
3283 remove a client from all channels it has joined to. Used when
3284 received SIGNOFF notify from server. Added also new function
3285 silc_client_replace_from_channels to replace old ID entry with
3286 new ID entry on all channels. Used when received NICK_CHANGE
3289 * Fixed ID Cache list handling in silc_idlist_get_client in
3290 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3291 to get (or query) client by ID.
3293 * Updated TODO list.
3295 * Added connection authentication status message defined by the
3296 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3297 support for these into the code in client and server side.
3299 * Added generic function silc_client_send_command to send any command
3300 with variable argument list. Application should use this function
3301 to send commands if the command functions provided by the library
3302 does not suite for the application's user interface needs.
3304 * Added new `failure' client operation. Application is notified about
3305 received failure packet if client is executing a protocol. In this
3306 case the protocol's execution has failed.
3308 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3309 is required by the protocol.
3311 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3312 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3315 * Added status flag to SilcSKE object to indicate realtime status
3316 of the SKE protocol.
3318 * Application receives now exactly same command reply arguments as
3319 the library receives from server. However, if ID is received the
3320 corresponding ID entry is returned to the application (eg. Client
3321 ID is mapped to correct SilcClientEntry entry and that is returned).
3322 Changed command_reply client operation due to this change.
3324 * Changed all ID's in commands and in command replys as ID Payloads.
3325 Change affected both client and server side codes.
3327 All ID's sent in SILC network (with execption of ID's in SILC
3328 Packet header) are sent in ID Payload to support variable length
3331 * Server now notifies nick changes and notifies all clients on
3332 the channels about the new nickname (about the new Client ID,
3335 * Implemented CMODE command to change channel modes. Supports all
3336 channel modes defined by the protocol specs except ban and invite
3337 lists. (Also, private channel key mode is supported but support for
3338 setting private channel key in client is missing, thus, this mode
3339 has no effect on client side (except that server requires that the
3340 client uses private channel key and normal channel traffic does not
3343 Also, invite mode works per se, but INVITE command does not work
3344 yet correctly, so you can set channel as invite only channel but
3345 inviting clients to the channel does not work (it is yet to be
3346 thought what's the best way to do it).
3348 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3349 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3350 Implemented CUMODE command to change user's mode on the channel.
3351 Supports all modes defined by the protocol specs.
3353 * Added NAMES command reply to return users modes on the channel.
3355 * Removed unnecessary and slow ciphers from lib/silccrypt.
3357 * Set SO_KEEPALIVE option to connection sockets by default.
3359 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3361 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3362 redefined the Notify Payload into protocol specs.
3364 * Added silc_id_payload_parse_id to get ID directly from raw
3367 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3370 accept searching by Client ID as well.
3372 * Added support for LEAVE and SIGNOFF notify types in client library.
3374 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3375 to parse ID Payload from raw data.
3377 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3379 * Added flags parameter into silc_ske_assemble_security_properties
3380 function in lib/silcske/silcske.[ch].
3382 * Changed notify client operation to fit better for notify messages
3383 sent by server. The notify payload received from server is now
3384 passed to the application (after parsing it to SilcNotifyPayload).
3385 It is application's responsibility to retrieve the arguments
3386 from the payload and show the message the way it wants. The message
3387 sent by server is implementation specific.
3389 * Changed public keys to comply with the protocol specification.
3390 Old public keys are not supported anymore and are not compatible.
3392 * Removed nickname from Channel Payload as the latest draft removed
3393 it. The client must resolve the nickname from the NAMES command
3394 reply received when it joined the channel.
3396 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3398 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * Fixed some errors in protocol specification drafts.
3402 * Created lib/silccore/silcnotify.c to implement Notify Payload
3403 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3404 generic payloads described by protocol specifications. The file
3405 includes implementations for ID Payload and Argument Payload.
3407 * Changed Command Payload implementation to use the new Argument
3408 Payload. Changed command_xxxx_payload to command_payload_xxxx
3409 to comply with SILC coding conventions.
3411 * Added suppport for Argument Payload handling in Notify Payload
3412 implementation as protocol requires it. Added the new support
3413 into server and client lib as well.
3415 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3417 * Added support for multiple nicknames on same channel. [n] is
3418 added locally to the nickname if there are more than one same
3419 nicknames on the channel.
3421 * Server now sends all nicknames that matched WHOIS request.
3422 Client also shows the list received from server.
3424 * Added TOPIC command to client side. User can now set and show
3425 current topic on channel.
3427 * Added MOTD command to client and server. Also, server sends the
3428 motd when client connects to the server.
3430 * Changed version strings to comply ISO 8601.
3432 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3434 * Fixed protocol error handling in client library. It should now
3435 cope even if the SKE fails for some reason.
3437 * Made new protocol specification drafts for submitting to IETF.
3439 * Implemented TOPIC command to server in silcd/command.c.
3441 * Added two new notify types into lib/silccore/silcnotify.h:
3442 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3443 notify nickname change and topic setting/change on a channel.
3445 * API change of command_reply operation in client library. The
3446 application gets now the status type received from server as well.
3448 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3450 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3452 * Cras fixed and optimized the packet handling even further and
3453 it should work now. Minor change to the prototype of function
3454 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3456 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Added new function into lib/silcutil/silcschedule.[ch]:
3459 silc_schedule_with_fd to select() a specified fd. The function
3460 returns after timeout expires or data arrives or goes. The
3461 function is used by packet routines to wait that all data is
3462 received from network.
3464 * Fixed data reading from network in lib/silccore/silcpacket.c.
3465 The code now assures that all data is read from the fd and then
3466 continues packet processing. This was a bug fix since the code
3467 used to drop some data in some circumstances.
3469 * Added new function into lib/silcclient/client.[ch]:
3470 silc_client_start_key_exchange to start key exchange after
3471 connection has been established to server. The code internally
3472 now uses this funtion but its main purpose was to provide it
3473 for applications that perform their own connecting. After
3474 application has created a connection it merely calls this
3475 function to start the key exchange between client and server.
3476 The library takes care of everything else after that.
3478 Updated also lib/silcclient/README to explain the usage of
3481 * Do not send to application information that connection has
3482 been established. Application gets notified it by connect
3485 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3487 * Applied cras's patch to add silc_schedule_one function. The
3488 function runs scheduler once and returns.
3490 * Fixed the scheduler after cras messed it up. The timeout
3491 handling works now as it's supposed to work.
3493 * Added into lib/silccore/ silcnotify.h to include notify
3494 message types support. Changed silc_server_send_notify*
3495 functions, in server.[ch], to support those new notify types.
3496 Added the support for the notify types into client library,
3497 as well. Added new notify client operation into ops.h in
3500 * Changed silc_server_packet_send_to_channel to send normal
3501 packets instead of just channel message packets. The function
3502 is now used to send the notify packets to channels. It is not
3503 used to send channel message packets anymore, as server never
3506 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3507 va_arg()s as it seems to require it nowadays. I guess, if SILC
3508 is compiled with older va_arg() the new code should work anyway.
3510 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3512 * Splitted core library. Core library (lib/silccore) includes
3513 now only SILC protocol specific core (and common) components.
3514 Created new utility library (lib/silcutil) that includes more
3515 generic purpose stuff. The stuff for util library was taken
3516 from the old core library. This was minor and easy split.
3518 * Created SILC Client Library (lib/silcclient) that includes
3519 implementation of the SILC client without user interface. This
3520 was major move from silc/ directory. The code has been changed
3521 so that it is transparent towards the user interface. The
3522 silc/ directory includes now the same user interface as before
3523 and it uses the new client library. Read lib/silcclient/README.
3524 Basicly, the client library performs everything else related
3525 to SILC except user interface handling. Also, configuration
3526 files are considered to be part of user interface and library
3527 does not handle them.
3529 This change also changed a lot of structures, function naming etc.
3530 Most important change was that SilcClientWindow object was
3531 renamed to SilcClientConnection in the client library. Created
3532 also new file lib/silcclient/ops.h. Also added new files
3533 silc/local_command.[ch] and silc/client_ops.[ch].
3535 All these changes were made to make it easier for user interface
3536 designers to create what ever user interface for the SILC client
3539 It is also expected that the server will be moved to lib
3540 directory as well and SILC Server Library will be created;
3541 sometimes in the future.
3543 * Removed Local commands from lib/silccore/silccommand.h as
3544 they are application specific and new client library does not
3545 handle any of those anymore.
3547 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3548 old client implementation in silc/.
3550 * Added support for callback functions in SILC_LOG_* macros.
3551 Application can now set its own callbacks that will be called
3552 instead of using the default functions that will always print
3553 the debug messages to stderr (or stdout). Also, debugging can
3554 now be disabled by setting silc_debug to FALSE and re-enabled by
3555 setting it to TRUE. Note, that logging will still work even
3556 if debugging is disabled.
3558 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3559 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3560 silc_log_reset_debug_callbacks.
3562 * To enable debugging in silc client one must give now -d
3563 option on command line.
3565 * Changed silc_schedule_init to automatically allocate task queues
3566 if they are not allocated before calling it.
3568 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Added GMP 3.1 into math library.
3572 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3575 a channel in SILC network. The packet is used by servers and
3576 routers to notify other routers that user has left a channel.
3577 This little feature was missing until now. Added the feature
3578 to protocol specification as well.
3580 Added functions: silc_server_send_remove_channel_user and
3581 silc_server_remove_channel_user into server.[ch].
3583 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3584 lib/silccore/silcpacket.h. However, they are not implemented
3587 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3589 * Fixed joining to a channel and sending channel messages
3590 between server and router. The channel message sending should
3591 now work inside a cell.
3593 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3595 * Fixed the private message sending between server and router.
3596 The private message sending should now work inside a cell.
3598 * Added silc_server_replace_id into server.[ch] to replace
3599 existing ID in the SILC network.
3601 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3602 and silc_idlist_replace_server_id into idlist.[ch] in server.
3604 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Fixed the server to server connections. Server can again now
3607 connect to router. Router to router connections probably does
3610 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3612 * Added dynamic protocol registering support. Now protocols can
3613 registered and unregistered on the fly. Patch by cras.
3615 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3617 * Added lib/contrib directory to hold routines that some platforms
3618 don't have but are needed by SILC.
3620 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3621 into lin/contrib to provide getopt() and getopt_long() for
3622 those who don't have it.
3624 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3626 * Added AWAY command to client. When away message is set and
3627 client receives a private message packet the client automatically
3628 replies to the sender with the away message.
3630 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3631 bug seemed to be the cause of recent problems when compiling
3634 * Added version detection support to SKE protocol specification
3635 and added the new changes to the SKE implementation as well.
3636 There were other minor changes in the SKE protocol as well.
3638 Many changes in lib/silcske/silcske.[ch] and in
3639 lib/silcske/payload.[ch].
3641 * Added ^U functionality, clear input line. Patch from cras.
3643 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Mainly small bugfixes on core library. Fixed some debugging
3646 logging and buffer overflow in silclog.c.
3648 * Updated config.sub and config.guess on the distribution tree.
3650 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Added command lagging support in server. Client may execute
3653 commands now only once in two seconds.
3655 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Optimized packet reception. MAC computation and checking is now
3658 also more optimized. A lot previously duplicated code is now
3659 used as generic by both client and server.
3661 * Fixed key pair generation in clientutil.c
3663 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Added into lib/silccore/silcbufutil.[ch] new function;
3666 silc_buffer_realloc.
3668 * Moved generic packet sending/encryption functions to
3669 lib/silccore/silcpacket.[ch] from client and server. Some
3670 rewriting of the functions.
3672 * Moved all generic packet reception/decryption functions to
3673 lib/silccore/silcpacket.[ch] from client and server. The
3674 packet processing is now much cleaner in both client and server.
3675 These were major changes in both client and server.
3677 * Created many common functions in server to do packet sending.
3678 Previously code were duplicated a lot, this has been removed
3681 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Rewrote major parts of the ID cache system. Don't know
3684 whether it is better now or not but at least the API is more
3687 * Major rewrite on ID cache stuff on client because of the ID
3688 cache API changes. Added idlist.c to client.
3690 * Also major rewrite on ID cache stuff on server as well.
3691 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3692 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3693 in hand, instead they are all put into the ID cache system now.
3694 All server_idlist_* routines uses ID cache now instead of
3695 traversing its own lists (those lists does not exist anymore).
3696 SilcIDList though still exists. Also, SilcXXXEntry's are
3699 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3701 * Finally made the SKE implementation compliant to the protocol
3702 specification. All mp integers are now binary encoded as
3703 opposed being HEX encoded.
3705 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3708 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3709 functions: silc_[encode/decode]_pem. Also added function
3710 silc_encode_pem_file to PEM encode with newlines ('\n') for
3713 * SILC public keys are now encoded either PEM or binary. Same
3714 option is for private keys as well. By default private keys
3715 are binary encoded and public keys PEM encoded. Silly HEX
3716 encoding were removed.
3718 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3719 function to create fingerprints.
3721 * Fixed a bug in SHA1; does not change the original data anymore.
3723 * Partly implemented INFO command on client and server side.
3724 Fixed CLEAR command. Changes to SERVER command; show current
3725 server(s) when giving command without arguments. Added
3726 VERSION command to client.
3728 * Added check to server that unregistered connections cannot
3729 execute commands (unless it is specificly allowed).
3731 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Fixed screen refresh.
3735 * Fixed channel joining bug from client. On some circumstances
3736 client tried to join to a channel it had already joined.
3738 * Added public key verification process into client's protocol.c.
3739 The client now verifies the public key from user and saves
3740 it into ~./silc/serverkeys/ directory.
3742 Added into: clientutil.[ch]: silc_client_verify_server_key.
3744 * Changed SKE protocol's silc_ske_initiator_finish function
3745 to accept callback function that verifies the received public
3746 key. Removed old silc_ske_verify_public_key function.
3748 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3750 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3751 silc_pkcs_private_key[_data]_set.
3753 * Made the password and public authentication more cleaner in
3754 server's protocol.c.
3756 * Removed historic and obsolete protocol `channel_auth' from
3757 both client and server.
3759 * Removed wrong way of sending command status messages from
3760 server to client in server's command.c. The old way violated
3761 protocol specification.
3763 Changes to silccore/silccommand.[ch]: removed
3764 silc_command_encode_status_payload -> not needed anymore,
3765 changed silc_command_encode_payload_va to accept extra
3766 argument on variable argument list. The argument type must
3767 now be provided to the function. Also, added new function:
3768 silc_command_encode_reply_payload_va which is same as
3769 normal command_encode_payload_va except command status type
3770 is provided as extra argument.
3772 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * Added ~./silc directory handling. The directory includes the
3775 public and private keys for the client.
3777 Added silc_client_check_silc_dir, silc_client_create_identifier
3778 and silc_client_load_keys.
3780 * Implemented SILC protocol compliant public key. Added public
3781 and private key saving to and loading from files.
3783 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3784 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3785 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3786 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3787 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3789 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3790 silc_pkcs_load_[public/private]_key.
3792 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3794 * Added silc_server_get_route (route.[ch]) to get connection
3795 data for the fastest route for given ID.
3797 * Implemented INVITE command on client and server. The command
3798 were re-defined in the SILC Protocol Specification and the
3799 implementation now complies with the specification.
3801 * Implemented PING command on client and server.
3803 * Implemented NAMES command on client and server. The server side
3804 supports currently only normal server not router server yet.
3805 Some changes to NAMES definition in SILC protocol specification.
3807 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Implemented LEAVE command on client and server.
3811 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3812 again. This change was made to the protocol as well. Server
3813 should not violate the protocol specification anymore.
3815 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3818 was tested. SOCKS4 was not but should work anyway.
