1 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added new function silc_hash_table_find_all to return all keys
4 in the hash table by the specified key. As the hash table is
5 collision resistant it also makes it possible to have several
6 duplicate keys in the hash table. This function may be used to
7 find all of the keys from the hash.
9 Added user_context arguments to the SilcHashFunction,
10 SilcHashCompare and SilcHashDestructor to deliver user specified
13 Added new fuctions silc_hash_table_find[_all]_ext to do
14 extended lookup with specified hash and compare functions and
15 specified user contexts.
17 Added new function silc_hash_table_add_ext to add the key
18 with specified hash function and user context.
20 Added new function silc_hash_table_foreach to traverse all
21 entrys in the hash table. Added SilcHashForeach callback
24 Added new function silc_hash_table_del_by_context to delete
25 the entry only if the context associated with the key matches.
27 Affected files are lib/silcutil/silchashtable.[ch].
29 * Removed silc_hash_[server/client/channel]_id and added just
30 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
31 silc_hash_id_compare to compare two ID's using as the hash table
32 comparison function. Added also silc_hash_data to hash
33 binary data and silc_hash_data_compare to compare it.
35 * Removed silc_idlist_find_client_by_hash as it is not needed
36 anymore. Affected file silcd/idlist.[ch].
38 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
39 to use internally the SilcHashTable. The new ID Cache is a lot
40 faster than the old one. Some of the ID Cache interface was also
41 rewritten and obsolete and stupid functions were removed.
43 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
45 * Added entry_count field to the SilcHashTable to keep the number
46 of the entries in the table. Implemented the function
47 silc_hash_table_rehash. Added new function
48 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
50 Fixed a minor bug in silc_hash_table_free.
52 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
53 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
54 into the lib/silcutil/silcutil.[ch].
56 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
58 * Implemented a collision resistant hash table into the
59 lib/silcutil/silchashtable[ch]. See the header and the source
60 for the SilcHashTable API.
62 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
64 * Merged dotconf version 1.0.2 into lib/dotconf.
66 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
68 * Do not compile anything in lib/silcsim/* if the SIM support
69 is not enabled. The tree should now compile without problems
72 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
74 * Compiled the SILC under cygwin. Compiled and tested briefly
75 without problems. More tests needed. The SIMs didn't compile
78 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
80 * Fixed possible crash in silc_get_username in the
81 lib/silcutil/silcutil.c.
83 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
85 * Fixed a va_arg in silc/client_ops.c.
87 * Oops, RC5 routines were named AES and caused some problems
88 when not using SIM's. Affected file lib/silccrypt/rc5.c.
90 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
92 * Added new SilcIDIP structure into the lib/silccore/id.h and
93 replaced the old `ip' fields from all SILC ID's to that type.
94 This is a step towards IPv6 support.
96 The silc_id_get_len takes now the ID as an extra argument.
97 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
98 both IPv4 and IPv6 based ID's.
100 The affected files are lib/silccore/id.[ch] and other files
101 around the tree using these routines.
103 * Removed the ID length arguments in server from various
104 silc_server_send_notify_* routines -> they are not needed
107 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Fixed memory leak in silc_encode_pem_file in the file
110 lib/silcutil/silcutil.c.
112 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
114 * Check minor version as well in the SKE. Affected files are
115 silcd/protocol.c and lib/silcclient/protocol.c.
117 * Added --identifier option to the server so that an identifier
118 can be when creating the public key for the server. Affected
119 file is silcd/silcd.c.
121 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
122 lib/silccrypt/silcpkcs.c.
124 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
126 * Register default ciphers and stuff when using -C option with
127 the server. Affected file sildc/silcd.c.
129 * Put back the servers public key filename format, it is better
130 than the new one. For now, the client keys are saved with the
131 new filename format. The affected file silc/client_ops.c.
133 * Implemented the Cipher API for the rest of the ciphers that
134 did not implement it or implemented it the wrong way.
136 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
138 * Register default ciphers and stuff when using the -S option
139 in the client. Affected file silc/silc.c. Same also when
140 creating new key pair with -C option.
142 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
144 * Fixed the silc_verify_public_key client operation function to
145 save the public keys differently. The fingerprint is now
146 used as filename and not the hostname. This way also the
147 client keys are saved uniquely and not with hostnames. The
148 affected file is silc/client_ops.c.
150 * Trimmed the silc_hash_fingerprint function to remove extra
151 whitespaces from the end of the fingerprint. The affected
152 file is lib/silccrypt/silchash.c.
156 * Added silc_cipher_register_default function to register all
157 default ciphers. It can be used when configuration files
158 does not exist and the application does not want any specific
159 ciphers in any specific order.
161 The SilcDList is now used as silc_cipher_list dynamically
162 allocated cipher list. Removed the static list all together
163 and now all ciphers must be allocated to the dynamic list.
164 The silc_cipher_alloc routine was changed to check only the
167 All silc_cipher_* routines that used to return int returns
170 The affected files lib/silccrypt/silccrypt.[ch].
172 * The same thing was done to silc_hash_* as for silc_cipher_*
173 routines. Affected files lib/silccrypt/silchash.[ch].
175 * The same thing was done to silc_pkcs_* as for silc_cipher_*
176 routines. Affected files lib/silccrypt/silcpkcs.[ch].
177 Added also silc_pkcs_[un]register[_default] functions.
178 Removed the data_context from the PKCS API.
180 * Added silc_hmac_register_default function to register default
181 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
182 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
183 to unregister all hmacs at once.
185 * Register the default ciphers, hash functions, PKCSs and HMACs
186 if client's configuration file does not exist. The affected
189 * The client did not load the hash functions from the SIM
190 modules at all. Added support for this. Affected file is
193 * When decoding public key with silc_pkcs_public_key_decode, check
194 the supported algorithm only if PKCS are registered. Affected
195 file lib/silccrypt/silcpkcs.c. The same was done with the
196 silc_pkcs_private_key_decode.
198 * Fixed the SILC List routines to keep the list always in order.
199 It used to change the list's order when traversing the list but
200 not it preserves the order. Affected file lib/trq/silclist.h.
202 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
204 * Added the client library to use the SilcSocketConnection's
205 reference counter (by silc_socket_dup) to prevent the bug that
206 the socket object may be freed underneath async operation.
208 * The name resolv library checking fixes in the configure.in.pre.
211 * Created new version of the protocol drafts for future
212 development. The -03 drafts are the ones that will be changed
213 in the trunk now and the -02 will remain as they are.
215 * Send list of CUMODE notifys to the router when announcing
216 the channel users to the router. Affected file silcd/server.c.
217 If the router receiving channel founder CUMODE for a channel
218 that already has channel founder it will send CUMODE notify
219 to the sender to remove the channel founder rights from the
220 announced client. Affected file silcd/packet_receive.c.
222 * The CUMODE notify may now use Server ID as well as the entity
223 who changes the mode. Updated protocool specs.
225 * Updated INSTALL and README files.
227 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
229 * New web pages in the http://silc.pspt.fi. The pages was
234 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Implemented the [DenyConnectin] config section in the server.
237 Added silc_server_config_denied_conn to check whether incoming
238 connection is denied. Affected file silcd/serverconfig.[ch].
240 * Do not check the ports when checking the incoming configuration
241 data if the port is 0, meaning any. Affected file is
242 silcd/serverconfig.c.
244 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
246 * Fixed buffer overflow in silc_string_compare in the file
247 lib/silcutil/silcutil.c.
249 * Fixed double free in silc_server_command_leave in the file
252 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

257 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
259 * Fixed the configuration data fetching when accepting new
260 connections in the server. Affected file silcd/server.c.
262 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
264 * Added `sender_entry' argument to the function
265 silc_server_packet_relay_to_channel so that we can check
266 whether some destination actually belongs to the same route
267 the sender belongs (ie, we must not resend the packet to the
268 sender). Affected file silcd/packet_send.[ch].
270 * Added `servername' field to the SilcClientEntry in the server
271 to hold the name of the server where client is from. Affected
272 file is silcd/idlist.h.
274 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
276 * Moved the channel message encrypting in the router betwen
277 router connections from silc_server_channel_message to the
278 silc_server_packet_relay_to_channel since we want to check
279 whether we have anybody channel before encrypting anything.
280 Affected files silcd/packet_[receive/send].c.
282 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
284 * Fixed the [AdminConnection] server config section to support
285 multiple entries. Affected file silcd/serverconfig.c.
287 * Added support into the server to check the validity of the
288 incoming connection before executing any KE or authentication
291 * The connection configuration is now saved to the KE and
292 connection auth protocol contexts and not fetched anymore in
293 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
295 * The local hosts listenning address and port is also resolved
296 now when starting the server. We want to have the socket object
297 to include the real address and port for the listener. Added
298 new function silc_net_check_local_by_sock into the files
299 lib/silcutil/silcnet.[ch].
301 * Fixed a broadcast bug in server -> do not broadcast if we
304 * Fixed a routing bug. Do not route broadcast packets ever.
305 Broadcast packets must be processed always and not routed since
306 they may be destined to some other host than yourself and thus
307 would get routed without no good reason. Affected file is
310 * Added function silc_server_config_is_primary_route to check
311 whether primary router connection has been configured (a router
312 configuration that we are initiating). If there is not, we
313 will assume that there is only two routers in the SILC network
314 and we will use the incoming router connection as our primary
315 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
317 * Changed the order of the broadcasting. Broadcast _after_ the
318 packet has been processed not before. Affected file is
321 * Fixed a [ClientConnection] parsing bug. The port was never
322 parsed correctly thus resulting to port 0. Affected file
323 silcd/serverconfig.c.
325 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
326 argument and did not set the broadcast packet flag. Affected
327 file silcd/packet_send.c. Fixed same bug in the function
328 silc_server_send_notify as well.
330 * If we receive NEW_ID packet for our own ID in the server, ignore
333 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
337 * Removed the nickname from the Private Message Payload.
338 Updated the code and the protocol specs.
340 * Updated protocol specs for submitting to the IETF.
342 * Tweaked the Random Number Generator a bit. Affected file
343 lib/silccrypt/silcrng.c. Exported a new function
344 silc_rng_[global]_add_noise which can be used to add more
347 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
349 * Do not parse packets with different timeout when protocol
350 is active -> may cause problem with rekey. Affected file
353 * When server receives signoff notify it must not create
354 new channel key if the client is on any channels since the
355 sender of the signoff notify will create it.
357 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
359 * Added printing of error messages during SKE protocol from the
360 failure packet sent by server during SKE. Affected file
363 * Removed the client's failure_callback handling with timeout
364 and handle it immediately when received.
366 * The SKE library returned wrong type in SUCCESS and FAILURE
367 packets. They must be 32 bit MSB not 16 bit MSB.
369 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
371 * Ok, rewrote the logic of the re-key and now it seems to work.
372 I tested it on high traffic with frequent re-keys without
373 problems. Added hmac_receive (and renamed hmac to hmac_send)
374 in SilcClientConnection in lib/silcclient/client.h and
375 in SilcIDListData in silcd/idlist.h. Also, removed the
376 SilcPacketParserContext's cipher and hmac fields as they are
377 not needed anymore and actually caused some problems when
378 the ciphers and hmac's changed underneath the packet parser.
380 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
382 * If re-key protocol is active then process the incoming packets
383 synchronously since we must assure that icoming packets encrypted
384 with the old key is processed before the new keys is set to
385 use. This is true other packets than for REKEY packets.
386 Affected file silcd/server.c. The same was done to client library
387 as well, affected file lib/silcclient/client.c.
389 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
391 * Fixed bug in client and server to accept the force send if
392 the packet is send from silc_[server/client]_packet_process
393 function. Otherwise the packets are never delivered, oops.
395 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
397 * Disable force sending of packets when REKEY protocol is active.
398 We must assure that no packet is sent directly when rekey is
399 performed. All packets must be sent through packet queue.
400 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
401 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
402 function is silc_[server/client]_packet_send_real to check
405 * Replaced the SIM paths from example config files to
406 /usr/local/modules. Also, make install creates now
407 /usr/local/silc/logs directory to hold all the SILC server
410 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

417 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
419 * Fixed the make install.
421 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
423 * When MAC computation fails the silc_packet_decrypt returned 0
424 even though it was supposed to return -1. Fixed this. The
425 affected file is lib/silccore/silcpacket.c.
427 * Do not replace the config files in /etc/silc (in make install)
428 if they already exist. Affected file ./Makefile.am.
430 * Do not send re-key packets immediately but through packet queue.
431 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
433 * Changed silc_net_check_host_by_sock to return FALSE if the
434 IP/DNS could not be resolved. Though, it returns the IP address
435 now even if it could not resolve it (but returns also FALSE).
436 Affected file lib/silcutil/silcnet.[ch].
438 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
440 * Added silc_pkcs_decode_identifier to decode the public key's
441 identifier. Affected file lib/silccrypt/silpkcs.[ch].
442 Added also silc_pkcs_free_identifier. Added also new context
443 SilcPublicKeyIdentifier.
445 * Added -S option to the silc client. It is used to dump the
446 contents of the specified public key file.
448 * Changed the PKCS api to return the public key length when
449 setting the public key.
451 * Fixed a fatal bug in the public and private key file loading.
452 Affected file lib/silccrypt/silcpkcs.c.
454 * Execute the packet parsing for client with zero (0) timeout
455 if the protocol is active. Affected file silcd/server.c.
457 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
459 * Made the key generation options to the silcd program. Added
460 -C option, equivalent to client's option.
462 * Added new [ServerKeys] config section to the server. It
463 configures the server's public and private key.
465 * Defined generic Public Key Payload into the protocol
466 specification to send specific type of public keys and
469 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
470 public key or certificate.
472 * Implemented the GETKEY command to the server and to the
473 client library and on user interface.
475 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

511 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
513 * Do not ask whether user wants to use the negotiated private key
514 for private messages, just use it. Affected file is
515 silc/local_command.c.
517 * Added `send_enc_key' and `enc_key_len' fields to the
518 SilcIDListData structure since they are needed in the re-key
519 phase. Affected file is silcd/idlist.[ch].
521 * Implemented the simple re-key protocol into the server.
522 Affected files silcd/server.c and silcd/protocol.[ch]. The

567 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
568 if the deleting was successful. Affected file silcd/idlist.[ch].
570 * Added support for public key authentication in the connection
571 authentication protocol in the client library. Affected file
572 lib/silcclient/protocol.c.
574 * Changed the server's silc_idlist_get_clients_by_* interface
575 to support already allocated array so that new entries may be
576 added to pre-allocated array. Affected file silcd/idlist.[ch].
577 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
580 * All command reply functions in the server now calls the
581 pending command callback even if error occured. This way the
582 error will be delivered to the client as well. Affected files
583 silcd/command.c and silcd/command_reply.c.
585 * Fixed INFO command to return local server's info if no server
586 was provided. Affected file lib/silcclient/command.c.
588 * Removed RESTART command for good. Updated the code and the
591 * Rewrote parts of the task system. It is a bit simpler now.
592 Removed unsued task priorities. The affected files are
593 lib/silcutil/silctask.[ch].
595 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
597 * Moved the USERS printing from the library to the application.
598 Affected files lib/silcclient/command.c and silc/client_ops.c.
600 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
604 * Added channel key re-key support. The re-key is perfomed
605 only by the router and is done once in an hour. Added `rekey'
606 field to the SilcChannelEntry in the server. Affected files
607 silcd/server.c and silcd/idlist.h.
609 * Added silc_task_unregister_by_context into the file
610 lib/silcutil/silctask.[ch].
612 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
614 * Added SILC_UMODE_GONE mode to indicate when the client is not
615 present in the SILC network. Added also support to the local
616 command AWAY that will set this mode. Added support of showing
617 "xxx is gone" in WHOIS command. The USERS command shows the
620 * Fixed setting server and router operator privileges in the
621 server's UMODE command. Affected file silcd/command.c.
623 * Merged the SKE KE1 and KE2 payloads into one payload. The
624 new KE payload is equivalent to the old KE2 payload.
626 Cleaned up the SKE Start Payload parsing. It now uses the
627 simple buffer unformatting to do the parsing. A lot faster
630 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
631 to the SKE that is used to indicate whether both of the SKE
632 parties should perform authentication. By default only the
633 responder performs authentication. By setting this flag also
634 the initiator must do authentication. By default it is unset
635 since in normal SKE case, client to server connection, only
636 the responder should do authentication. When doing SKE between
637 two clients both should perform authentication. Updated the
638 code and the protocol specs.
640 * A little fix to IDENTIFY command in the server. Search the
641 client first by hash not nickname. Affected file is
644 * Fixed the silc_client_close_connection to support closing
645 the client to client connections wihtout deleting too much
646 data. Affected file lib/silcclient/client.c.
648 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
649 are received if protocol used to be active but is not anymore
650 the application would crash due to NULL pointer dereference.
651 Affected files silcd/server.c and lib/silcclient/client.c.
653 * Added `hash' field to the SilcClientConnection to include
654 the hash function negotiated in the SKE protocol.
656 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
657 to set the channel founder authentication data. A client can
658 claim the founder rights later by providing the authentication
659 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
660 This way the channel founder can regain the channel founder
661 privileges even it is left the channel. This works only on
662 local server and the client must be connected to the same
663 server to be able to regain the founder rights. Updated the
664 protocol specs accordingly.
666 Added support to the CMODE command in the client to set the
667 founder auth data. Read the README to see how to set it.
669 Added support to the CUMODE command to claim the founder
670 rights. Read the README to see how to do it.
672 Added support for the founder authentication to the Channel
673 Entry in the server. Affected file silcd/idlist.h.
675 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
676 server's CMODE command. Affected file silcd/command.c.
678 * Added the following new functions into lib/silccore/silcauth.[ch]:
679 silc_auth_get_method and silc_auth_get_data.
681 * The server now saves the remote hosts public key to the
682 SilcIDListData pointer. Affected file silcd/protocol.c.
684 * The normal server now does not remove the channel entry from
685 the cache if the founder authentication data is set. It used
686 to remove it if the founder was the last one on the channel on
687 the server and left the channel. The auth data is saved and
688 if the channel is re-joined later the old entry is used with
689 the old auth data. Affected files silcd/command_reply.c and
692 * Removed the `pkcs' field from the SilcIDListData structure
693 in the server; it is not used. Affected file silcd/idlist.h.
695 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
697 * Fixed packet processing on slow links. Partial packets were
698 never re-processed because the incoming data buffer was cleared
699 by the application. Application must not directly clear the
700 sock->inbuf, the packet processing routines handle it. Fixed
701 this in client library and in server.
703 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
705 * Fixed the WHOIS and IDENTIFY send reply function to really
706 check whether to send list or just one entry. Affected file
709 * Cleaned up the LEAVE command's channel key distribution. The
710 affected file silcd/command.c.
712 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
713 can enforce the channel mode as well. In that case the ID
714 includes the ID of the server. The code now enforces the
715 mode change if the router have different mode than the server.
717 * The notify client operation with CMODE_CHANGE notify can now
718 return NULL client_entry pointer if the CMODE was not changed
719 by client. Application must check for this.
721 * Added <Server ID> argument to INFO command to support server
722 info fetching by Server ID.
724 * Added silc_server_announce_get_channel_users to get assembled
725 packets of channel users of the specified channel. Affected
726 file silcd/server.[ch].
728 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
729 was freed underneath the ID Cache.
731 * Re-announce clients when the server received CHANNEL_CHANGE
732 notify from the router. Affected file silcd/packet_send.c.
734 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
736 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
737 crashed since it did not handle the fact that there is no cipher
738 called "3" and didn't check the error condition. Now fixed.
740 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
741 flag. It can be used to send message requests.
743 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
745 * Implemented the RESTART command in the client.
747 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
748 notice type messages. Added notice printing to the user
751 * The channel keys are not re-generated if the channel's mode
752 is PRIVKEY, ie private key on the channel exists. Affected
753 files silcd/server.c and silcd/command.c.
755 * Fixed a little bug in channel message delivery when channel
756 private keys are set in the server. Affected file is
759 * Changed the setting on channel->on_channel = TRUE from the
760 silc_client_save_channel_key to the JOIN command reply. The
761 key payload is not received if the private channel key is set.
762 Affected file lib/silcclient/command_reply.c and the
763 lib/silcclient/client_channel.c.
765 * When the CMODE_CHANGE notify is sent and the channel private
766 key mode is removed the channel key must be re-generated in
767 other cells as well. Added this support for the router in the
768 silcd/packet_receive.c.
770 * Added new local command NOTICE to send notice message on
771 channel. Affected file silc/local_command.[ch].
773 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
775 * Added new local command ME to the client. It is used to send
776 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
777 some action. Affected file silc/local_command.[ch].
779 * Changed channel_message and private_message client operations
780 to deliver the message flags to the application. Added also
781 the `flags' arguments to the silc_client_send_channel_message
782 and silc_client_send_private_message functions. Affected file
785 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * Redefined the Private Message Payload to support private message
788 keys and to support the new private message flags. Updated
789 the protocol specs. Flags makes it possible to have for example
792 * Added new type SilcPrivateMessagePayload and defined an API
793 for it in the lib/silcclient/silcprivate.[ch].
795 * Tested private message private keys successfully. Tested the
796 private message key set, unset and list commands with the new
799 * Redefined the Channel Message Payload to include the channel
800 message flags (equal with private message flags) to support
801 for example CTCP style messages.
803 * Defined some of the message (for channel and private message)
804 flags. Updated the protocol specs and added the flags to the
805 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
807 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * Added SilcKeyAgreementStatus type to the key agreement routines
810 to indicate the current status and error if one occured.
811 The status types are defined in the lib/silcclient/silcapi.h.
813 * Added new local command KEY that is used to set and unset private
814 keys for channels, set and unset private keys for private messages
815 with remote clients and to send key agreement requests and
816 negotiate the key agreement protocol with remote client. The
817 key agreement is supported only to negotiate private message keys,
818 it currently cannot be used to negotiate private keys for channels,
819 as it is not convenient for that purpose.
821 * Fixed a minor pending callback setting bug in the function
822 silc_client_get_client_by_id_resolve, now the function works.
823 Affected file lib/silcclient/idlist.c.
825 * Added function silc_net_get_local_port to get local bound
826 port by socket. Added to lib/silcutil/silcnet.[ch].
828 * Added `sockets' and `sockets_count' fields to the SilcClient
829 object. They hold the sockets of the listenning sockets in
830 the client. Listenning sockets may be for example the key
831 agreement server. Affected file lib/silcclient/client.[ch].
832 Added functions the silc_client_add_socket and the
833 silc_client_del_socket. They are exported to the application
836 * Added ~./silc/clientkeys to support other client's public keys.
838 * Renamed verify_server_key client operation to verify_public_key
839 and added one argument to indicate the type of the connection
840 (server, client etc.).
842 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
844 * Added silc_server_connection_auth_request to handle the
845 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
846 silcd/packet_receive.[ch].
848 * Added silc_server_send_connection_auth_request into the
849 silcd/packet_send.c to send the connection auth request packet.
851 * Cleaned up the silcd/protocol.c a bit and fixed some memory
854 * Fixed the public key authentication in responder side in the
855 server. The `auth_data' pointer includes the SilcPublicKey
856 not the path to the public key. Affected file silcd/protocol.c.
858 * Implemented the public key authentication in the initiator side
859 in the server. Affected file silcd/protocol.c.
861 * Removed the [RedirectClient] config section from the server
862 configuration. Is not needed and I don't want to implement it.
864 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
866 * Cleaned up the CMODE command in the server. It now works
867 correctly and supports all the modes defined in the protocol.
868 Affected file is silcd/command.c.
870 * Added `hmac_name' field to the SilcChannelEntry in the server
871 to hold the default HMAC of the channel. It can be set when
872 creating the channel (with JOIN command). Affected files
875 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
876 type to indicate the change of the current cipher and hmac
877 on the channel. Client can safely ignore the <cipher> argument
878 (if it chooses to do so) since the CHANNEL_KEY packet will
879 force the channel key change anyway. The <hmac> argument is
880 important since the client is responsible of setting the new
881 HMAC and the hmac key into use.
883 * Fixed the CMODE command in the client library as well.
885 * Tested CMODE command in router environment successfully.
887 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
889 * Show the version of the remote client (or server) when connecting
890 to the server. It is logged to the log file. Affected file
893 * Fixed the KILLED notify handling in the client library. The
894 client must be removed from all channels when receiving the
897 Also, do not remove the client entry when giving the KILL
898 command but when the KILLED notify is received.
900 * Removed silc_idlist_find_client_by_nickname from the server.
901 Not needed anymore. Affected files silcd/idlist.[ch].
903 * Implemented the CHANNEL_CHANGE notify type handling to the
904 server. Affected file silcd/server.c.
908 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

923 client entry by ID from all ID lists and then resolve it
924 (using WHOIS) if it cannot be found. Affected file is
927 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
929 * Implemented the BAN command to the client library.
931 * The JOIN command in the server now checks the invite list

936 NULL it ignores and checks the next argument. Affected file
937 lib/silccore/silccommand.c.
939 * Added silc_server_send_notify_ban to send the BAN notify
940 type between routers.
942 * Chaned the silc_notify_payload_encode to support that if
943 argument is NULL it ignores and checks the next argument.
944 Affected file lib/silccore/silcnotify.c.
946 * Tested ban lists in router environment successfully.
948 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
950 * Implemented BAN command to the server, in silcd/command.[ch].
952 * Removed the BAN and INVITE_LIST modes from the CMODE command
955 * Added function silc_string_match to regex match two strings.
956 Affected files lib/silcutil/silcutil.[ch].

961 the new ban and invite lists.
963 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
965 * Redefined the INVITE command. The same command can be used to
966 invite individuals to the channel but also to manage the invite
967 list of the channel (to add to and remove from the invite list).
968 Updated the protocol specs.
970 * Added new command SILC_COMMAND_BAN that can be used to manage
971 the ban list of the channel. Updated the protocol specs.
973 * Removed the channel modes: the SILC_CMODE_BAN and the
974 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
975 in the CMODE command. The equivalent features are now available
976 using INVITE and BAN commands. Updated the protocol specs.
978 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
979 in the network about change in the current ban list. The notify
980 type is not used by the client.
982 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
983 support the invite lists.
985 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Added new function silc_string_regexify that converts string
988 including wildcard characters into regex string that can
989 be used by the GNU regex library. Added into the file
990 lib/silcutil/silcutil.[ch].
992 Added silc_string_regex_combine to combine to regex strings

1026 With private channels the user count is not shown.
1028 * Updated TODO and README.
1030 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1032 * The client entry's data.registered must be TRUE even with
1033 global client entry on global client list. The data.registered
1034 is used to check whether the client is anymore in the network,
1035 for example with WHOWAS command so it must be valid.
1037 * Fixed the WHOWAS command in the server. It now actually works
1038 in router environment. Added function into silcd/command_reply.c
1039 silc_server_command_reply_whowas_save.
1041 * Added silc_idlist_purge function to the silcd/idlist.c
1042 to periodically purge the ID Cache.

1048 * Fixed minor bug in silc_idcache_purge to not purge if the
1049 expire value is zero.
1051 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1052 they were buggy because of the WHOWAS information.
1054 * Fixed local command MSG to handle the async resolving of
1055 the remote client properly. It used to fail the first MSG.
1056 Affected file silc/local_command.c.
1058 * Added `data_len' field to SilcIDCache context.
1060 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1062 * Update TODO. Todo in commands in the server.

1087 of channels the client has joined for WHOIS command reply.
1088 Affected file silcd/server.[ch].
1090 * Implemented the channel list sending in the WHOIS command reply
1091 in server and in the client.
1093 Implemented the channel list displaying on the user interface
1094 as well. Affected file silc/client_ops.c.
1096 * Added silc_channel_payload_parse_list to parse list of Channel
1097 Payloads. It returns SilcDList list of SilcChannelPayloads.
1098 Client for example can use this function to parse the list of
1099 channels it receives in the WHOIS command reply. The caller
1100 must free the list by calling silc_channel_payload_list_free.
1101 Affected files lib/silccore/silcchannel.[ch].
1103 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * Added one new argument <user mode> to the WHOIS command reply

1122 unknown command. Affected file silcd/command.c.
1124 * All server commands now handle the command identifier the right
1125 way when sending the command reply to the client. The client can
1126 use to identify the command replies with the identifier.
1128 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1130 * Added silc_server_get_client_route to resolve the route to
1131 the client indicated by the client ID. Affected file is
1134 * Added silc_server_relay_packet as general function to relay
1135 packet to arbitrary destination. This deprecates functions
1136 like _send_private_message_key, _relay_notify etc. Affected
1137 file is silcd/packet_send.[ch].
1139 Removed silc_server_send_key_agreement,

1153 printing in the user inteface.
1155 * Fixed a lot silc_parse_nick memory leaks from the client
1156 library in the file lib/silcclient/command.c.
1158 * Changed the silc_server_send_notify_on_channels's `sender'
1159 argument from SilcSocketConnection to SilcClientEntry to
1160 check the sender as entry and not as connection object and not
1161 to send to the client provided as argument. The affected file
1162 is silcd/packet_send.[ch].
1164 * The notify packets that are destined directly to the client used
1165 to not to be processed by the server. Now changed that and the
1166 server processes all notify packets. After relaying the packet
1167 to the client the notify packet is processed in the server.
1169 * The silc_server_free_client_data now checks whether there is
1170 pending outgoing traffic for the client and purges the data to
1171 the network before removing the client entry.
1173 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1175 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1176 an client is killed from the SILC Network. Updated the protocol
1179 Added new function silc_server_send_notify_killed to the
1180 silcd/packet_send.[ch].
1182 * Added function silc_server_packet_relay_notify to relay notify
1183 packets that are destined directly to a client. In this case
1184 the server does not process the notify packets but merely relays
1185 it to the client. Affected file silcd/packet_send.[ch].
1187 Added also silc_server_packet_process_relay_notify to check
1188 whereto relay the notify. Affected file is
1189 silcd/packet_receive.[ch].
1191 * Implemented the KILL command to the server.
1195 * Added the backup schema desgined last fall to the protocol
1196 specs for everyone to see. The specification is in the
1197 *-spec-xx.txt draft and the packet type definitions for the
1198 backup routers is in *-pp-xx.txt draft. Thusly, added also
1199 new packet type SILC_PACKET_CELL_ROUTERS.
1201 * A big security problem in the implementation discovered. The
1202 signoff of an client did not cause new channel key generation
1203 which it of course should've done. The channel keys must be
1204 always re-generated when client leaves (or signoffs) the channel.
1205 The silc_server_remove_from_channels funtion now handles
1206 the channel key re-generation.
1208 * Added `sender' argument to the silc_server_send_notify_on_channels
1209 to not to send the client provided as argument. Affected file
1210 silcd/packet_send.[ch].
1212 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1214 * Implemented OPER and SILCOPER commands into the server and
1217 * Added silc_auth_verify and silc_auth_verify_data to verify
1218 the authentication directly from the authentication payload.
1219 It supports verifying both passphrase and public key based
1220 authentication. Affected file lib/silccore/silcauth.[ch].
1222 * Added `hash' field to the SilcIDListData structure. It is the
1223 hash negotiated in the SKE protocol. Affected file is
1226 * Slight redesigning of the SilcAuthPayload handling routines.
1227 Do not send SilcPKCS but SilcPublicKey as argument.
1229 * Implemented the public key authentication support to the
1230 serverconfig. The public key is loaded from the provided path
1231 and saved as authentication data to void * pointer. Thus,
1232 changed the unsigned char *auth_data to void *auth_data;
1234 * Fixed SHUTDOWN command to send the reply before the server
1235 is shutdown. :) Affected file silcd/command.c.
1237 * Fixed fatal bug in CONNECT command. The hostname was invalid
1238 memory and server crashed. Affected file silcd/command.c.
1240 * Fixed fatal bug in CLOSE command. The server_entry became
1241 invalid but was referenced later in the command. Affected file
1244 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1246 * Fixed fatal bug in failure packet handling. Server ignored
1247 the failure and thus crashed when it came.
1251 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1253 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1254 that the command may be executed only once in (about) 2 seconds.
1255 The old SILC_CF_LAG flag is same but allows command bursts up
1256 to five before limiting.
1258 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1259 server code. Various commands now includes the CF_LAG_STRICT
1260 flag to disallow any kind of miss-use of the command.
1262 * Fixed the silc_buffer_unformat to not to allocate any data
1263 if the length of the data is zero. It used to allocate the
1264 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1266 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Changed the format of AdminConnection configuration section
1269 in the server. Added username of the admin to the format.
1270 Affected files silcd/serverconfig.[ch].
1272 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1273 to return admin configuration data by host, username and/or
1276 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1278 * Implemented WHOWAS command to the server. Added the functions:
1280 silc_server_command_whowas_parse,
1281 silc_server_command_whowas_send_reply,
1282 silc_server_command_whowas_from_client and
1283 silc_server_command_whowas_from_server
1285 * Added <Client ID> argument to the WHOWAS command reply. Updated
1286 the protocol specs accordingly.
1288 * Implemented WHOWAS command and command_reply to the client
1291 Implemented the WHOWAS printing on the user interface.
1293 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1295 * Added new argument to the WHOWAS command reply, the real name.
1296 It is an optional argument. Updated the protocol specs.
1298 * Added SilcIDCacheDestructor callback that is registered when
1299 the SilcIDCache is allocated. The callback is called when
1300 an cache entry in the ID Cache expires, or is purged from the
1301 cache. Added into lib/silccore/idcache.[ch].
1303 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1304 to destruct the client entries when the cache entry expires.
1305 Other ID Cache's in server and in the client library ignores
1308 * If the ID Cache entry's `expire' field is zero then the entry
1309 never expires. Added boolean `expire' argument to the
1310 silc_idcache_add function in the lib/silccore/idcache.[ch].
1311 If it is TRUE the default expiry value is used.
1313 * Added silc_server_free_client_data_timeout that is registered
1314 when client disconnects. By default for 5 minutes we preserve
1315 the client entry for history - for WHOWAS command.
1317 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1319 * Added support to the server to enforce that commands are not
1320 executed more than once in 2 seconds. If server receives
1321 commands from client more frequently, timeout is registered
1322 to process the commands. Affected file silcd/command.c.
1323 Added new function silc_server_command_process_timeout.
1325 * Changed NICK_NOTIFY handling in client library to check that
1326 if the client's nickname was changed, so there is no need to
1327 resolve anything from the server.
1329 * Removed error printing from the WHOIS and IDENTIFY commands.
1330 If error occurs then it is ignored silently in the client library.
1331 The application, however, may map the received error to
1332 human readable error string. The application currently maps
1333 the NO_SUCH_NICKNAME error to string.
1335 * Made the command status message public to the application. Moved
1336 them from lib/silcclient/command_reply.c to
1337 lib/silcclient/command_reply.h. The application can map the
1338 received command status to the string with the
1339 silc_client_command_status_message function.
1341 * Added check to the server to check that client's ID is same
1342 as the Source ID in the packet the client sent. They must
1345 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1347 * Added dist-bzip hook to the Makefile.am to make bzip2
1348 compressed distributions.
1350 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1352 * Server now enforces the maximum length for the nickname and
1353 the channel as protocol specification dictates. 128 bytes for
1354 nickname and 256 bytes for channel name.
1356 * Moved the WHOIS printing to the application. The client libary
1357 does not print out the WHOIS information anymore, the application
1358 must do it. Renamed silc_client_command_reply_whois_print to
1359 the silc_client_command_reply_whois_save.
1361 The client's idle time is also sent to the application now, and
1362 the idle is shown on screen.
1364 * Added silc_client_command_reply_identify_save to save the
1365 received IDENTIFY entries.
1367 * Do not check for channel private keys in message sending and
1368 reception if the channel does not have the PRIVKEY mode set.
1369 Affected file lib/silclient/client_channel.c.
1371 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1373 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1374 just surfaced after chaning the JOIN procedure.
1376 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1378 * Added silc_client_get_clients_by_list to get client entries
1379 from Client ID list, that is returned for example by JOIN
1380 and USERS command replies. The application should use this
1381 function for example when JOIN command reply is received to
1382 resolve the clients already on the channel (library does not
1383 do that anymore as USERS command reply is not used in the JOIN
1384 procedure anymore). Affected files lib/silcclient/silcapi.h and
1385 lib/silcclient/idlist.c.
1387 * JOIN command reply and USERS command reply returns now SilcBuffer
1388 pointers instead of unsigned char pointers when returning
1389 the client list and mode list.
1391 * Added <Client ID> argument to the JOIN command reply, mainly
1392 for the server to identify for which client the command was
1393 originally sent. Updated protocol specs accordingly.
1395 * Added SilcDlist private_key pointer to the SilcChannelEntry
1396 in the client to support the channel private keys. Affected
1397 file is lib/silcclient/idlist.h.
1399 * Added SilcChannelPrivateKey argument to the function
1400 silc_client_send_channel_message so that application can choose
1401 to use specific private ke if it wants to. If it is not provided,
1402 the normal channel key is used, unless private keys are set.
1403 In this case the first (key that was added first) is used
1404 as the encryption key.
1406 * Implemented the support for channel private key handling.
1407 Implemented the following functions:
1409 silc_client_add_channel_private_key,
1410 silc_client_del_channel_private_keys,
1411 silc_client_del_channel_private_key,
1412 silc_client_list_channel_private_keys and
1413 silc_client_free_channel_private_keys
1415 Affected file lib/silcclient/client_channel.c.
1417 * Added the support for the private keys in the channel message
1418 sending and encryption and in the message reception and
1419 decryption. Affected funtions are
1420 silc_client_send_channel_message and silc_client_channel_message.
1422 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1424 * Added SKE's key verify callback to the client library's
1425 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1427 * Removed the statement that server (or router) must send USERS
1428 command reply when joining to the channel so that the client
1429 knows who are on the channel. Instead, the client list and
1430 client's mode list is now sent in the JOIN command reply to the
1431 client who joined channel. This is better solution.
1433 * Added function silc_server_get_users_on_channel and function
1434 silc_server_save_users_on_channel to the silcd/server.[ch].
1436 * Removed function silc_server_command_send_users from the
1439 * Do not show topic on the client library anymore. The topic is
1440 sent in the command reply notify to the application and the
1441 application must show the topic now.
1443 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1445 * Added client searching by nickname hash into the IDENTIFY and
1446 WHOIS commands in the server as they were clearly missing from
1447 them. Affected file is silcd/command.c.
1449 * Fixed a bug in private message receiving in the client library.
1450 The remote ID was freed and it wasn't supposed, now it is
1453 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Minor fix to the channel payload; allocate the data area, as it
1456 needs to be of specific length.
1458 * If the key agreement port is zero then the operating
1459 system will define the bound port. Affected files are
1460 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1462 * Added new function silc_channel_payload_decrypt into the file
1463 lib/silccore/silcchannel.[ch].
1465 * Moved the channel message etc, check from silc_packet_decrypt
1466 to applications. The library calls now a generic
1467 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1468 when the packet is either normal or special. This was done to
1469 allow more wide range of checking that was not allowed when
1470 the code was in library. Now applications can do virtually any
1471 checks to the packet and return to the library the decision how
1472 the packet should be processed. Affected files are
1473 lib/silccore/silcpacket.[ch].
1475 Added silc_server_packet_decrypt_check to the server and
1476 silc_client_packet_decrypt_check to the client library.
1478 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1479 to send with specified source and destination information.
1481 * Channel message delivery between routers was broken after the
1482 channel key distribution was fixed earlier. The channel key
1483 was used be to distributed to other routers as well which is not
1484 allowed by the protocol. Now this is fixed and channel keys
1485 really are cell specific and the channel message delivery between
1486 routers comply with the protocol specification.
1488 * Fixed various commands in server to check also the global list
1489 for the channel entry and not just the local list. The affected
1490 file silcd/command.c.
1492 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1494 * Added assert()s to buffer formatting and unformatting routines
1495 to assert (if --enable-debug) when error occurs. Affected
1496 file: lib/silcutil/silcbuffmt.c.
1498 * Changed to auto-reconnect to check whether the remote host is
1499 router and register the re-connect timeout if it is. It used
1500 to check that whether we are normal server, but router must do
1501 auto-reconnect with another router as well. Affected file
1504 * Removed the [<key len>] option from CMODE command as the cipher
1505 name decides the key length, nowadays. See the defined ciphers
1506 from the protocol specification.
1508 * Added [<hmac>] option to the CMODE command to define the HMAC
1509 for the channel. Added SILC_CMODE_HMAC channel mode.
1511 * Added [<hmac>] option for the JOIN command so that user can
1512 select which HMAC is used to compute the MACs of the channel
1515 * Added Hmac field to the Channel Message Payload. The integrity
1516 of plaintext channel messages are now protected by computing
1517 MAC of the message and attaching the MAC to the payload. The
1518 MAC is encrypted. Now, it is clear that this causes some
1519 overhead to the size of the packet but rationale for this is that
1520 now the receiver can verify whether the channel message decrypted
1521 correctly and also when private keys are set for the channel the
1522 receiver can decrypt the packet with several keys and check from
1523 the MAC which key decrypted the message correctly.
1525 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1526 lib/silccrypt/silccipher.[ch].
1528 * Added silc_hash_len to return the digest length into the
1529 lib/silcrypt/silchash.[ch].
1531 * Rewrote parts of Silc Channel Payload interface in the
1532 lib/silccore/silcchannel.[ch]. The encode function now also
1533 encrypts the packet and parse function decrypts it.
1535 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * Fixed a minor formatting bug in the SKE's key material processing.
1538 It actually might have processed the keys wrong way resulting
1541 * Redefined the mandatory HMAC algorithms and added new algorithms.
1542 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1543 and hmac-md5 truncated to 96 bits. The mandatory is now
1544 hmac-sha1-96. Rest are optional (including the one that used
1545 to be mandatory). Rationale for this is that the truncated HMAC
1546 length is sufficient from security point of view and can actually
1547 make the attack against the HMAC harder. Also, the truncated
1548 HMAC causes less overhead to the packets. See the RFC2104 for
1551 * Added new [hmac] configuration section. The SKE used to use
1552 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1553 is of course wrong. The official names that must be proposed in
1554 the SKE are the ones defined in the protocol specification
1555 (hmac-sha1-96 for example). The user can configure any hmac
1556 using any hash function configured in the [hash] section. At
1557 least, the mandatory must be configured.
1559 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1561 * Added HMAC list to the SKE proposal list. It has now both
1562 hash algorithm list and HMAC list. This makes the protocol
1563 incompatible with previous versions. The SKE now seems to work
1564 the way it is supposed to work, for the first time actually.
1566 * Defined plain Hash algorithms to the protocol specification.
1569 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1571 * Implemented support for key agreement packets into the server.
1572 Added functions silc_server_key_agreement and
1573 silc_server_send_key_agreement. Other than these functions,
1574 server has nothing to do with this packet.
1576 * Added support for private message key packets into the server.
1577 Added functions silc_server_private_message_key and
1578 silc_server_send_private_message_key.
1582 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1583 called in the protocol's final callback instead in the END
1584 protocol state. This makes a little more sense and in the same
1585 time in client we can use the same protocol routines for normal
1586 key exchange and to key agreement packet handling as well.
1588 * Added to both client's and server's KE protocol context the
1589 SilcSKEKeyMaterial pointer to save the key material. We will
1590 bring the key material to the protocol's final callback by doing
1591 this. The final callback must free the key material.
1593 * Added SKE's packet_send callback into client's KE protocol
1594 context so that the caller can choose what packet sending function
1595 is used. This way we can use different packet sending when
1596 doing normal SKE when doing key agreement packet handling (in
1597 the key agreement packet handling we do not want to encrypt
1600 * Implemented the responder side of the key agreement routines
1601 in the client. The client can now bind to specified port and
1602 accept incoming key negotiation. The key material is passed
1603 to the application after the protocol is over.
1605 * Implemented the processing of incoming Key Agreement packet
1606 in the client. Added function silc_client_key_agreement to
1609 * Implemented the intiator side of the key agreement routines
1610 in the client. The client can now initiate key agreement with
1611 another remote client. The key material is passed to the
1612 application after the protocol is over.
1614 * Created client_keyagr.c to include all the key agreement
1617 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1618 SILC_TASK_CALLBACK except that it is not static.
1620 * Created client_notify.c and moved the Notify packet handling
1621 from the client.[ch] into that file.
1623 * Created client_prvmsg.c and moved all private message and
1624 private message key routines from the client.[ch] into that file.
1626 * Create client_channel.c and moved all channel message and
1627 channel private key routines from the client.[ch] into that file.
1629 * Changed silc_client_get_client_by_id_resolve to resolve with
1630 WHOIS command instead of IDENTIFY command, in the file
1631 lib/silclient/idlist.c.
1633 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1635 * Implemented the SKE's responder side to the Client library.
1637 * When FAILURE is received to the protocol do not trust it
1638 blindly. Register a timeout to wait whether the remote closes
1639 the connection as it should do it, only after that process the
1640 actual failure. This was changed to both client and server.
1642 * Added client_internal.h to include some of the structures
1643 there instead of client.h in lib/silcclient/.
1645 * Added function silc_task_unregister_by_callback to unregister
1646 timeouts by the callback function.
1648 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1650 * Some "Incomplete WHOIS info" errors has been appearing on the
1651 log files. Took away the entry->userinfo check from WHOIS
1652 reply sending. The entry->userinfo is now " " if client did not
1653 provide one. I thought this was fixed earlier but something
1654 is wrong still. Let's see if the error still appears.
1656 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1658 * Fixed a minor bug in the login when the channel key is
1659 re-generated in the server. It used to generate the key in
1660 wrong order and thus caused problems in the channel traffic.
1662 * Fixed a minor bug in channel key distsribution after
1663 KICK command. The key was not sent to the router even though
1666 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1668 * Added silc_ske_process_key_material_data as generic routine
1669 to process any key material as the SILC protocol dictates. The
1670 function is used by the actual SKE library but can be used by
1671 applications as well. This relates to the private message keys
1672 and the channel private keys since they must be processed the
1673 same way the normal SILC session keys. The protocol dictates
1674 this. Affected files: lib/silcske/silcske.[ch].
1676 Added also silc_ske_free_key_material to free the
1677 SilcSKEKeyMaterial structure.
1679 * Defined silc_cipher_set_key function to set the key for
1680 cipher without using the object's method function. The affected
1681 files: lib/silccrypt/silccipher.[ch].
1683 * Implemented silc silc_client_add_private_message_key,
1684 silc_client_add_private_message_key_ske,
1685 silc_client_del_private_message_key,
1686 silc_client_list_private_message_keys and
1687 silc_client_free_private_message_keys functions in the
1690 Added functions silc_client_send_private_message_key to send
1691 the Private Message Key payload and silc_client_private_message_key
1692 to handle incoming Private Message Key payload.
1694 * Added Cipher field to the Private Message Key payload to set
1695 the cipher to be used. If ignored, the default cipher defined
1696 in the SILC protocol (aes-256-cbc) is used.
1698 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1700 * Removed lib/silcclient/ops.h file.
1702 Redefined parts of the SILC Client Library API. Created new
1703 file silcapi.h that deprecates the ops.h file and defines the
1704 published Client Library API. Defined also private message key
1705 API and channel private key API into the file.
1707 This is the file that the application must include from the
1708 SILC Client Library. Other files need not be included by
1709 the application anymore.
1711 * Added new key_agreement client operation callback and also
1712 defined the Key Agreement library API for the application.
1714 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1717 is used by clients to request key negotiation between another
1718 client in the SILC network. If the negotiation is started it
1719 is performed using the SKE protocol. The result of the
1720 negotiation, the secret key material, can be used for example
1721 as private message key.
1723 Implemented the Key Agreement payload into the files
1724 lib/silccore/silauth.[ch].
1726 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1728 * Redefined ciphers for the SILC protocol. Added some new ciphers
1729 and defined the key lengths for the algorithms. Changed the
1730 code accordingly. The default key length is now 256 bits.
1732 * Fixed SKE key distribution function silc_ske_process_key_material
1733 when the key length is more than 128 bits. The default key
1734 length in SILC is now 256 bits.
1736 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1737 to indicate unsupported algorithm.
1739 * Renamed rijndael.c to aes.c and all functions as well.
1741 * Fixed a long standing channel key setting bug in client library.
1742 Weird that it has never surfaced before.
1744 * Fixed bug in channel deletion. If the entire channel is removed
1745 then it must also delete the references of the channel entry
1746 from the client's channel list as the client's channel entry and
1747 the channel's client entry share same memory.
1749 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1751 * Implemented CONNECT and SHUTDOWN commands in the client.
1753 * Implemented CLOSE command to the client.
1755 * Added the function silc_idlist_find_server_by_name into the
1756 files silcd/idlist.[ch].
1758 Added the function silc_idlist_find_server_by_conn into the
1759 files silcd/idlist.[ch].
1761 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1763 * DIE command was renamed to SHUTDOWN. Updated the both code
1766 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1767 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1769 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1772 * Added function silc_server_create_connection function to create
1773 connection to remote router. My server implementation actually
1774 does not allow router to connect to normal server (it expects
1775 that normal server always initiates the connection to the router)
1776 so the CONNECT command is only good for connecting to another
1779 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1781 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1782 or some other client was kicked from the channel.
1784 Implemented the handling of the notify type to both client
1787 Implemented silc_server_send_notify_kicked to send the KICKED
1788 notify. It is used to send it to the server's primary router.
1790 * Implemented the KICK command into server and client.
1792 * Added `query' argument to the silc_idlist_get_client function
1793 to indicate whether to query the client from server or not if
1796 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1797 to indicate that the client is not channel founder.
1801 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1803 * Removed the rng context from SilcPacketContext structure and
1804 changed that the packet routine uses the Global RNG API.
1806 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1808 * Added support for quit message that client can "leave" on the
1809 channel when it quits the SILC. It is ditributed inside the
1810 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1812 Added silc_server_free_client_data that will take the
1813 signoff message as argument.
1815 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1817 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1819 * Updated parts of the protocol specification to keep it up
1822 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1825 payloads in one packet.
1827 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1828 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1829 use now the new List flag.
1831 * Also deprecated the following packet types: REPLACE_ID,
1832 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1834 * Added list support for Notify packet in server.
1836 * Added silc_server_send_notify_channel_change to send the
1837 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1838 the silc_server_send_replace_id.
1840 * Added silc_server_send_notify_nick_change to send the
1841 NICK_CHANGE notify type. Deprecates the function
1842 silc_server_send_replace_id.
1844 * Added silc_server_send_notify_join to send the JOIN notify type.
1845 Deprecates the function silc_server_send_new_channel_user.
1847 * Added silc_server_send_notify_leave to send LEAVE notify type.
1848 Deprecates the function silc_server_send_remove_channel_user.
1850 * Added silc_server_send_notify_cmode and
1851 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1852 types. Deprecates the silc_server_send_set_mode function.
1854 * Added SERVER_SIGNOFF notify type to indicate that server has
1855 quit. This means that all clients on the channel from that
1856 server will drop. This can be also used when netsplit happens.
1858 Deprecated REMOVE_ID packet type since it is not needed anymore
1861 Added silc_server_send_notify_server_signoff to send the
1862 SERVER_SIGNOFF notify type. Deprecates the function
1863 silc_server_send_remove_id.
1865 Added also silc_server_send_notify_signoff to send the
1866 SIGNOFF notify type.
1868 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1869 SILC protocol from this day on. Changed the protocol
1870 specification as well.
1872 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1873 notify type. It is used between routers to notify about
1874 topic changes on a channel.
1876 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1879 * Partly updated the protocol specification to comply with the
1880 changes now made. It is still though a bit outdated.
1882 * The JOIN notify type now takes one extra argument <Channel ID>.
1883 The packet used to be destined to the channel but now the
1884 JOIN type may be sent as list thus it is impossible to
1885 destine it to any specific channel. By adding this argument
1886 it is again possible.
1888 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Added CREDITS file. The CHANGES and CREDITS file will appear
1891 in the distribution as well.
1893 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1895 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1896 types in the server's silcd/packet_receive.c.
1898 * Implemented CMODE and CUMODE to work in router environment.
1900 * Fixed minor encoding and decoding buglet from the
1901 lib/silccore/silcmode.c.
1903 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1906 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1908 * Changed all SilcConfigServer* and silc_config_server* to
1909 SilcServerConfig* and silc_server_config*, respectively.
1912 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1914 * Associated the ID (client or server ID) to the Authentication
1915 Payload to avoid any possibility of forging. Updated the
1916 protocol specification and the code accordingly.
1918 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * The RSA key length is now save to the RsaKey context in the
1921 key generation process in lib/silccrypt/rsa.c. The key length
1922 is now used to figure out the maximum size of the block allowed
1923 to be encrypted/signed.
1925 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1926 is equivalent to the silc_mp_mp2bin but does not allocate any
1929 * Changed silc_mp_mp2bin API to take length argument. If it is
1930 non-zero then the buffer is allocated that large. If zero, then
1931 the size is approximated using silc_mp_sizeinbase, which however
1934 * Created Global RNG API which is global RNG that application can
1935 initialize. After initializing, any routine anywhere in the
1936 code (including library) can use RNG without allocating a new
1937 RNG object. This was done to allow this sort of use of the
1938 RNG in code that has no chance to allocate RNG object. All
1939 applications currently allocate this and many routines in the
1940 library use this. Affected file lib/silccrypt/silcrng.[ch].
1942 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1943 it to use the Global RNG API.
1945 * Defined Authentication Payload into protocol specification that
1946 is used during SILC session to authenticate entities. It is
1947 used for example by client to authenticate itself to the server
1948 to obtain server operator privileges.
1950 Implemented this payload into the lib/silccore/silcauth.[ch].
1951 Implemented also routines for public key based authentication
1952 as the new protocol specification dictates.
1954 Moved definitions of different authentication methods from
1955 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1957 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1958 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1959 silc_pkcs_verify_with_hash functions into the file
1960 lib/silccrypt/silcpkcs.[ch].
1962 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1964 * The client entry's userinfo pointer must be always valid.
1965 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1966 will fail since it requires the userinfo. Now, the userinfo
1967 is allocated as "" if actual userinfo does not exist. Actually,
1968 it must exist and it is totally Ok to drop client connections
1969 that does not announce the userinfo. However, we will make
1970 this workaround for now.
1972 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1973 to return the remote port by socket.
1975 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1977 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1978 SILC_SERVER_PENDING_EXEC and added an new macro
1979 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1980 data or when error occurs while processing the pending command.
1982 Added new argument `destructor' into silc_server_command_pending
1983 and to the SilcServerCommandPending object. This destructor is
1984 now called after calling the pending callback or if error occurs
1985 immediately. If error occurs the actual pending callback won't
1986 be called at all - only the destructor. The destructor may be
1987 NULL if destructor is not needed.
1989 All this applies for client library code as well. Similar
1990 changes were made there as well for the pending commands.
1992 In the client, the application must now allocate the
1993 SilcClientCommandContext with the silc_client_command_alloc
1996 * Added reference counter to the SilcServerCommandContext. Added
1997 function silc_server_command_alloc and silc_server_command_dup
2000 Same type of functions added to the client library for the same
2003 * Removed the cmd_ident from IDListData away since it is now
2004 global for all connections. It is the command identifier used
2005 in command sending and with pending commands. The affected file
2008 * Added reference counter to the SilcSocketConnection objecet to
2009 indicate the usage count of the object. The object won't be
2010 freed untill the reference counter hits zero. Currently only
2011 server uses this, and client ignores it. The client must be
2012 set to use this too later. The affected files are
2013 lib/silccore/silcsockconn.[ch]. Added also the function
2014 silc_socket_dup to increase the reference counter.
2016 This was mainly added because it is possible that the socket
2017 is removed underneath of pending command or other async
2018 operation. Now it won't be free'd and proper DISCONNECTING
2019 flags, etc. can be set to avoid sending data to connection that
2020 is not valid anymore.
2022 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2023 the connection. After that it sets SILC_SET_DISCONNECTED.
2024 It is, however, possible that the socket data is not still freed.
2025 The silc_server_packet_process now checks that data is not
2026 read or written to connection that is DISCONNECTED. The socket
2027 get's freed when the reference counter hits zero.
2029 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2031 * Changed the client operation API: channel_message operation's
2032 `sender' is now the client entry of the sender, not the nickname
2033 and the `channel' is the channel entry, not the channel name.
2035 In the private_message operation the `sender' is now also the
2036 client entry of the sender not the nickname.
2038 Affected file is lib/silcclient/ops.h and all applications
2039 using the client operations.
2041 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2043 * Moved the calling of ops->connect() from connect_to_server_final
2044 into receive_new_id functin since that is the point when the
2045 client is actually allowed to send traffic to network. The
2046 affected file is lib/silcclient/client.c.
2048 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2051 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2052 (if needs broadcasting) instead of broadcasting the packets one
2053 by one which would make a burst in the network traffic.
2055 * Added `broadcast' argument to the functions in silcd/server.[ch]
2056 silc_server_create_new_channel[_with_id] to indicate whether
2057 to send New Channel packet to primary router.
2059 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * Added new function into the silcd/server.[ch] files:
2062 silc_server_create_new_channel_with_id to create new channel with
2063 already existing Channel ID.
2065 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2066 lib/silccore/silcpacket.h. This packet is used t send list of
2067 Set Mode payloads inside one packet. Server uses this to set
2068 the modes for the channels and clients on those channels, that it
2069 announced to the router when it connected to it. The protocol
2070 specification has been updated accordingly.
2072 * The silc_server_new_channel did not handle the packet coming
2073 from normal server as it normally does not send that. However,
2074 when it announces its channels it does send it. Implemented
2075 the support for that.
2077 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2078 into the file lib/silccore/id.h.
2080 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2082 * Fixed memory leaks in the functions silc_idlist_del_client,
2083 silc_idlist_del_channel and silc_idlist_del_server in the file
2084 silcd/idlist.c. All of those leaked like a sieve.
2086 * Fixed some small memory leaks in the client's function
2087 silc_client_notify_by_server.
2089 * Added functions into silcd/server.c: silc_server_announce_clients,
2090 silc_server_announce_channels and silc_server_announce_server.
2091 These functions are used by normal and router server to announce
2092 to its primary router about clients, channels and servers (when
2093 router) that we own. This is done after we've connected to the
2096 These functions effectively implements the following packet types:
2097 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2098 and SILC_PACKET_NEW_ID_LIST.
2100 * Added new functions into the silcd/packet_receive.[ch]:
2101 silc_server_new_id_list, silc_server_new_channel_list and
2102 silc_server_new_channel_user_list to handle the incoming
2103 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2105 * Added support of changing Channel ID in the function
2106 silc_server_replace_id. If the server that announces a channel
2107 to the router already exists in the router (with same name but
2108 with different Channel ID), router is responsible to send
2109 Replace ID packet to the server and force the server to change
2110 the Channel ID to the one router has.
2112 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2113 client that the Channel ID has been changed by the router. The
2114 normal server sends this to the client. Client must start using
2115 the new Channel ID as the channel's ID.
2117 Implemented handling of this new type into lib/silcclient/client.c
2118 into the function silc_client_notify_by_server.
2120 * Added new function silc_idlist_replace_channel_id into the files
2121 silcd/idlist.[ch] to replace the Channel ID.
2123 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2125 * Call silc_server_command_identify_check always when processing
2126 the IDENTIFY command in silcd/command.c
2128 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2130 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2131 send keepalive packets. The packet can be sent by clients,
2132 servers and routers.
2134 Added function silc_socket_set_heartbeat into the file
2135 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2136 If not set, the heartbeat is not performed. The actual
2137 heartbeat is implemented in the low level socket connection
2138 library. However, application is responsible of actually
2141 Added silc_server_send_heartbeat to send the actual heartbeat
2142 packet into silcd/packet_send.[ch]. Server now performs
2143 keepalive with all connections.
2145 * Added silc_task_get_first function into lib/silcutil/silctask.c
2146 to return the timeout task with shortest timeout. There was a bug
2147 in task unregistration that caused problems. TODO has been
2148 updated to include that task system must be rewritten.
2150 * The client library will now resolve the client information when
2151 receiving JOIN notify from server for client that we know but
2152 have incomplete information.
2154 * Rewrote parts of silc_server_remove_from_channels and
2155 silc_server_remove_from_one_channel as they did not remove the
2156 channel in some circumstances even though they should've.
2158 * Encryption problem encountered in server:
2160 The LEAVE command used to send the Channel Key packet to the
2161 router immediately after generating it. However, the code
2162 had earlier sent Remove Channel user packet but not immediately,
2163 ie. it was put to queue. The order of packets in the router
2164 was that Channel Key packet was first and Remove Channel User
2165 packet was second, even though they were encrypted in the
2166 reverse order. For this reason, MAC check failed. Now, this
2167 is fixed by not sending the Channel Key packet immediately but
2168 putting it to queue. However, this is more fundamental problem:
2169 packets that are in queue should actually not be encrypted
2170 because packets that are sent immediately gets encrypted
2171 actually with wrong IV (and thus MAC check fails). So, packets
2172 that are in queue should be encrypted when they are sent to
2173 the wire and not when they put to the queue.
2175 However, the problem is that the current system has not been
2176 designed to work that way. Instead, the packet is encrypted
2177 as soon as possible and left to the queue. The queue is then
2178 just purged into wire. There won't be any fixes for this
2179 any time soon. So, the current semantic for packet sending
2182 o If you send packet to remote host and do not force the send
2183 (the packet will be in queue) then all subsequent packets to the
2184 same remote host must also be put to the queue. Only after the
2185 queue has been purged is it safe again to force the packet
2188 o If you send all packets immediately then it safe to send
2189 any of subsequent packets through the queue, however, after
2190 the first packet is put to queue then any subsequent packets
2191 must also be put to the queue.
2193 Follow these rules and everything works fine.
2195 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2197 * Added new function silc_server_remove_clients_by_server to
2198 remove all client entries from ID list when the server connection
2199 is lost. In this case it is also important to invalidate all
2200 client entires as they hold the invalid server entry. This
2201 fixes fatal bug when server has lost connection and will reconnect
2204 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2206 * Made some sanity checks to silc_server_daemonise like to check
2207 whether the requested user and group actually exists.
2209 * Added sanity check to SKE's silc_ske_responder_finish to check
2210 that the public and private key actually is valid.
2212 * Invalidate the client's nickname when receiving Replace ID
2213 packet and the Client ID is being replaced. This means that the
2214 server will query the nickname if someone needs it (client)
2217 * Sort the ID Cache in client library when the ID Cache data
2218 has changed (needs sorting).
2220 * Do not allow for SILC client to create several connections to
2221 several servers. The client does not support windows right now
2222 and generating multiple connections causes weird behaviour.
2224 Irssi-silc client does support windows and can handle several
2225 connections without problems, see: www.irssi.org and SILC plugin.
2227 * Fixed some places where client was added to the IDList. The
2228 rule of thumb is following (in order to get everything right):
2229 If the client is directly connected local client then the
2230 `connection' argument must be set and `router' argument must be
2231 NULL to silc_idlist_add_client function. If the client is not
2232 directly connected client then the `router' argument must
2233 bet set and the `connection' argument must be NULL to the
2234 silc_idlist_add_client function.
2236 * The funtion silc_server_packet_send_local_channel actually did
2237 not check whether the client was locally connected or not. It
2238 does that now. Fixed a bug related to LEAVE command.
2240 * Fixed Remove Channel User payload parsing bug in server's
2241 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2243 * The server's silc_server_save_channel_key now checks also the
2244 global ID list for the channel as it might not be in the local
2245 list. Fixed a bug related to LEAVE command.
2247 * Is this the end of the [<unknown>] buglet that has been lurking
2248 around for a long time? A little for loop fix in server's
2249 silc_server_command_whois_parse that is used by both IDENTIFY
2250 and WHOIS command. At least, this was a clear bug and a cause
2251 of one type of [<unknown>] buglet.
2253 * WHOIS and IDENTIFY commands call the function
2254 silc_server_command_[whois/identify]_check function even if
2255 we are not router server.
2257 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2259 * Added --with-gmp configuration option. If set the GMP
2260 is always compiled in the SILC source tree. If not set then
2261 it is checked whether the system has the GMP3 installed. If
2262 it has then the GMP won't be compiled (the system's headers
2263 and library is used), if it doesn't have it then the GMP is
2264 compiled in the SILC source tree.
2266 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2268 * Changed RSA private exponent generation to what PKCS #1
2269 suggests. We try to find the smallest possible d by doing
2270 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2271 not security fix but optimization.
2273 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2275 * Added new config entry [Identity] to fork the server and run
2276 it as specific user and group. A patch from Bostik.
2278 * Imported Dotconf configuration library into lib/dotconf.
2279 This will be used to create the SILC configuration files later.
2280 It will appear in the distsribution after this commit.
2282 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2284 * A big code auditing weekend happening. Auditing code for
2285 obvious mistakes, bugs and errors. Also, removing any code
2288 Removed files for being obsolete:
2290 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2291 inline in the file lib/silcutil/silcbuffer.h)
2293 o lib/silcutil/silcbufutil.c (the header has inline versions)
2295 Changed code to fix possible error conditions:
2297 o The buffer formatting routines now check that the destination
2298 buffer really has enough space to add the data. This applies for
2299 both buffer formatting and unformatting
2300 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2301 unformatting was changed to accomodate following rules:
2302 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2303 sent to the function while XXX_*STRING will not allocate or copy
2304 the data into the buffer. Instead it sets the pointer from the
2305 buffer into the pointer sent as argument (XXX_*STRING used to
2306 require that the pointer must be allocated already). This change
2307 makes this whole thing a bit more consistent and more optimized
2308 (note that the data returned in the unformatting with XXX_*STRING
2309 must not be freed now). The routines return now -1 on error.
2311 o Tried to find all code that use buffer_format and buffer_unformat
2312 and added return value checking to prevent formatting and
2313 especially unformatting errors and possible subsequent fatal
2316 o Changed ske->x and ske->KEY to mallocated pointers in
2317 lib/silcske/silcske.h. Fixed possible data and memory leak.
2319 o Added return value checking to all *_parse* functions. Fixed
2320 many memory leaks as well.
2322 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2323 so that buffer overflows would not happen. All code now also
2324 checks the return value as it can fail.
2326 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2328 * Added reconnection support to server if the normal server looses
2329 its connection to the router (for example if router is rebooted).
2330 The server performs normal reconnection strategy implemented
2331 to the server. Affected file silcd/server.c.
2333 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2335 * Added new packet type SILC_PACKET_SET_MODE that is used to
2336 distribute the information about changed modes (for clients,
2337 channels and clients channel modes) to all routers in the
2338 network. Updated the protocol specification accordingly.
2340 Added functions into silcd/packet_send.c and
2341 silcd/packet_receive.c: silc_server_send_set_mode,
2342 silc_server_set_mode.
2344 Added new files silcmode.[ch] into lib/silccore that implements
2345 the encoding and decoding of Set Mode Payload. Added new type
2346 SilcSetModePayload. Moved the definitions of different modes
2347 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2349 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2351 * Oops, a little mistake in server's connection authentication
2352 protocol. The protocol is not ended with FAILURE but with
2353 SUCCESS if the authentication is Ok. :) Affected file is
2356 * Implemented NICK_CHANGE notify handling in server in the file
2357 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2358 the local clients on the channel. After the changing nickname
2359 in router environment snhould work and the [<unknown>] nickname
2360 should appear no more.
2362 The silc_server_replace_id function that receives the Replace ID
2363 payload now sends the NICK_CHANGE notify type also in the file
2364 silcd/packet_receive.c
2366 * Changed WHOIS and IDENTIFY command to support the maximum amount
2367 of arguments defined in protocol specs (3328 arguments). This
2368 fixed a bug that caused problems when there were more than three
2371 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2373 * Added extra parameter, command identifier, to the
2374 silc_client_send_command so that explicit command identifier
2377 Changed that ID list routines uses specific command identifier
2378 when sending WHOIS/IDENTIFY requests to the server so that they
2379 can be identified when the reply comes back.
2381 Affected files lib/silcclient/command.[ch],
2382 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2384 * Added `sender' argument to silc_server_packet_send_to_channel
2385 to indicaet the sender who originally sent the packet to us
2386 that we are now re-sending. Ignored if NULL. Affected file
2387 silcd/packet_send.[ch].
2389 * Added some server statistics support in silcd/server_internal.h
2390 SilcServerStatistics structure and around the server code. Also
2391 send some nice statistics information when client is connecting
2394 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2396 * Fixed channel ID decoding in server's JOIN command reply in
2397 silcd/command_reply.c
2399 * Fixed braodcasting of replace ID payload to not to send it if
2400 we are standalone server in silcd/packet_receive.c.
2402 * Fixed all channel message sending routines to not to send
2403 packets to clients that has router set, since they are routed
2404 separately in the same function earlier. Affects file
2405 silcd/packet_send.c and all channel packet sending functions.
2407 * In USERS reply, res_argv[i] are not allocated, the table
2408 is allocated. Thus changed that free the table, not its
2411 * In server's whois_check and identify_check if the client is
2412 locally connected do not send any WHOIS commands - they are not
2415 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2417 * Fixed some minor bugs in client when sending WHOIS command. The
2418 arguments was in wrong order.
2420 * Removed statis function add_to_channel from server in
2421 silcd/command.c that was previously used with the joining but
2424 * Tested USERS command in router environment successfully with two
2425 routers, two servers and two clients.
2427 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2429 * Reorganized the USERS command and command reply in client library
2430 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2431 When the command is given by user we register a pending command
2432 callback that will reprocess the command after the reply has been
2433 received from the server. When reprocessing the packet we then
2434 display the information. Thus, the USERS information is displayed
2435 now in the command callback instead of in the command reply
2436 callback. The processing of the command is same as previously
2437 when server has sent the command reply in the JOINing process.
2439 * Added to USERS command in silcd/command_reply.c to join the client,
2440 we didn't use to know about, to the channel after we've created
2441 a client entry for it. Also, for clienet we did know already still
2442 check whether it is on the channel or not and add it if not.
2444 * Removed silc_server_command_join_notify as the function and its
2447 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2449 * Changed the client's pending command handling to the same as the
2450 server's pending command handling. It is also now possible to
2451 execute command reply functions from other command reply
2452 function as the function callbacks for commands and command
2453 replies are one and same. The pending commands are not static
2454 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2455 in client connection context. Thus, pending commands are server
2456 connection specific as it is convenient.
2458 Changed the function silc_client_command_pending and
2459 silc_client_command_pending_del and added new function
2460 silc_client_command_pending_check. Removed the
2461 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2464 * Added cmd_ident, current command identifier, to the client
2465 connection context in lib/silcclient/client.h to keep track on
2466 command identifiers used in command sending. Client's command reply
2467 function handling now supports the mandatory command identifiers.
2469 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2470 funtions in client to fully support pending command callbacks.
2472 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2473 as one of the arguments to the application in the command reply
2476 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2477 before first releasing SILC but came back. Now it is removed again
2478 and should come back nomore. The FORWARDED flag was used only
2479 by the JOINing procedure by forwarding the command packet to router.
2480 Now, the JOINing procedure has been changed to more generic (due
2481 to various router environment issues) and FORWARDED is not needed
2482 anymore for anything. The protocol specification is yet to be
2485 Now, removed silc_server_packet_forward from server and the flag
2486 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2488 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Renamed NAMES command to USERS command. The NAMES was named that
2491 due to historical reasons. Now it is renamed. Also, rewrote
2492 parts of the USERS command. The nickname list is not sent anymore
2493 by the server. Only Client ID and mode lists are sent in the USERS
2494 command. Changed this also to the protocol specification.
2496 The client now resolves the names and stuff after it receives
2497 the USERS list from the server when joining to the channel.
2499 * WHOIS and IDENTIFY commands has been changed to support multiple
2500 Client ID's per command. One can now search for multiple users
2501 in the network by sending only one WHOIS or IDENTIFY command.
2502 Changed the code and the protocol specifications.
2504 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2505 uses silc_server_command_whois_parse to parse the request. */
2507 * If normal server, do not parse the WHOIS and IDENTIFY requests
2508 before sending it to the router. Saves some time.
2510 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2512 * Fixed JOIN command on client library. Wrong number of arguments
2513 used to crash the client.
2515 * Added silc_server_channel_has_global function to check whether
2516 channel has global users or not.
2518 * Added silc_server_channel_has_local function to check whether channel
2519 has locally connected clients on the channel.
2521 * The silc_server_remove_from_one_channel now checks whether the
2522 channel has global users or not after given client was removed from
2523 the channel. It also checks whether the channel has local clients
2524 on the channel anymore. If it does not have then the channel entry
2525 is removed as it is not needed anymore.
2527 * The silc_server_notify now checks on JOIN notify whether the joining
2528 client is one of locally connected or global. If it is global then
2529 the channel has now global users on the channel and that is marked
2530 to the channel entry. Also, it now saves the global client to
2531 global list who is joining and JOINs it to the channel. This is
2532 for normal server, that is.
2534 Changed silc_server_send_notify_on_channel,
2535 silc_server_packet_relay_to_channel and
2536 silc_server_packet_send_to_channel check if we are normal server
2537 and client has router set (ie. global client) do not send the
2538 message to that client, as it is already routed to our router.
2540 * Implemented LEAVE notify type handling in silc_server_notify
2543 * Tested LEAVE command in router environment successfully. Tested
2544 with two routers, two servers and two clients.
2548 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2550 * Implemented SIGNOFF notify type handling in silc_server_notify
2553 * silc_server_remove_id now removes the client entry from all channels
2554 it has joined and thusly sends SIGNOFF notify type.
2556 * Rewrote the NAMES list generation in server by removing two excess
2557 loops. The lists are created now inside one loop.
2559 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2561 * silc_server_remove_channel_user checks now also global list
2562 for channel and client.
2564 * silc_server_new_channel_user checks now both local and global
2565 list for channel and client. Fixed a bug in client id decoding.
2566 Used to decode wrong buffer.
2568 * silc_server_channel_message checks now both local and global
2569 list for channel entry.
2571 * Tested channel joining (hence JOIN) in router environment
2572 successfully. Tested with two routers, two servers and two
2575 * Tested channel message sending in router environment successfully.
2577 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2579 * Added silc_server_save_channel_key into server.[ch] to save the
2580 received channel key in Channel Key payload processing. It is
2581 also used in JOIN command reply handling.
2583 Equivalent function silc_client_save_channel_key added into
2584 client.[ch] into client library.
2586 * Changed JOIN command reply to send information whether the channel
2587 was created or not (is existing already) and the channel key
2588 payload. Changed protocol specs accordingly.
2590 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2591 the request was sent by ID and not by nickname. Crashed on
2594 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2597 now correctly save the received data.
2599 * silc_server_free_sock_user_data now notifies routers in the
2600 network about entities leaving the network.
2602 At the same time implemented functions silc_server_remove_id
2603 and silc_server_send_remove_id to receive and send REMOVE_ID
2604 packets. The packet is used to notify routers in the network
2605 about leaving entities. The ID removed will become invalid in
2608 * Added function silc_idlist_del_server into server. Removes and
2609 free's server entry from ID list.
2611 * silc_server_private_message function now checks, if we are router,
2612 that the destination ID really is valid ID, naturally.
2614 * In router when NEW_ID packet is received (for new client) the
2615 hash of the Client ID is saved in the ID Cache but the
2616 client->nickname is set to NULL, instead of putting the hash
2619 IDENTIFY command now also checks that client->nickname must be
2620 valid. If it is not if will request the data from the server who
2621 owns the client. Added new function
2622 silc_server_command_identify_check.
2624 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2625 to set the command to already allocated Command Payload.
2627 * Tested private message sending in router environment with two
2628 routers, two servers and two clients. Fixed minor bugs and now
2631 * Fixed segfault from client's NAMES command. Used to crash if
2634 * Forwarded packets must not be routed even if it is not destined
2635 to the receiver. Changed server code comply with this.
2637 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Added `require_reverse_mapping' boolean value to ServerParams
2640 structure. If TRUE (not default) the server will require that
2641 the connecting host has fully qualified domain name.
2643 If the reverse mapping is not required and hostname could not be
2644 found the IP address is used as hostname.
2646 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * Implemented version string checking to both client and server.
2649 The check is incomplete currently due to the abnormal version
2650 strings used in development version of SILC.
2652 * Changed all command functions in server to use the new
2655 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Changed char *data to unsigned char *data in ID Cache system to
2658 support binary data as ID Cache data. Changed code to support
2659 binary data in lib/silccore/idcache.c.
2661 * Renamed silc_server_packet_relay_command_reply to
2662 silc_server_command_reply as it is normal packet receiving
2663 function. Rewrote the function to accept command replys for
2664 servers and not only for clients.
2666 * Mark remote router always as registered server if we are connecting
2667 to it. Otherwise, commands sent by the router to us are ignored.
2669 * All ID List find routines now returns the ID Cache Entry pointer
2670 as well if requested.
2672 * WHOIS command works now in router environment, tested with two
2673 routers, two servers and two clients.
2675 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2676 in router environment (as it is almost equivalent to WHOIS) but
2677 hasn't been tested thoroughly. Added new functions:
2679 silc_server_command_identify_parse
2680 silc_server_command_identify_send_reply
2681 silc_server_command_identify_from_client
2682 silc_server_command_identify_from_server
2684 * Disabled route cache adding because adding two different ID's with
2685 same IP replaces the old cache entry thus giving wrong route.
2686 The entry->router->connection is always the fastest route anyway
2687 so route cache may not be needed. Of course, new routes maybe
2688 established after receiving the ID when the entry->router->connection
2689 might not be anymore the most optimal.
2691 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2693 * Add route cache for received ID for fast routing.
2695 * Added silc_server_packet_route to route received packet on router
2696 that is not destined to us.
2698 * Renamed silc_server_get_route to silc_server_route_get.
2700 * Added id_string and id_string_len fields into SilcServer to
2701 include encoded ServerID for fast comparing without excess
2702 encoding of the ID's.
2704 * Cleaned up WHOIS command on server side. Added following static
2707 silc_server_command_whois_parse
2708 silc_server_command_whois_check
2709 silc_server_command_whois_send_reply
2710 silc_server_command_whois_from_client
2711 silc_server_command_whois_from_server
2713 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2714 arguments in command replies. All command functions should be
2715 updated to use this macro.
2717 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2719 * Minor typo fixes on command reply handling on server.
2721 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Added silc_server_command_add_to_channel internal routine to add
2724 the client to the channel after router has created the channel and
2725 sent command reply to the server.
2727 * Added generic silc_server_send_command to send any command from
2730 * Use static buffer with ID rendering instead of duplicating data.
2732 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2734 * Fixed a channel user mode bug when joining to a channel server gave
2735 everybody channel founder rights, oops.
2737 * We mark ourselves as the router of the incoming server connection
2738 if we are router ourselves. This way we can check in some packet
2739 sending functions whether it is locally connected server. For
2740 incoming router connections we put NULL.
2742 * For router sending packets locally means now always sending the
2743 packet cell wide; to local clients and local servers. For normal
2744 server sending packet locally means sending it to only local
2747 * Fixed the JOIN command to really work in router environment. If the
2748 channel is created it is always created by the router. Router is
2749 also responsible of making the initial joining to the channel,
2750 sending JOIN notify to the sending server and distributing
2751 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2752 does not exist server doesn't do anything else but forward the
2753 command to the router which performs everything.
2755 * Added silc_server_send_channel_key function to send the Channel Key
2758 * Added silc_server_create_channel_key to create new channel key. The
2759 channel key is now re-generated everytime someone joins or leaves
2760 a channel, as protocol dictates. Note: channel->key_len is the
2763 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2765 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2766 packet_receive.[ch] to separate packet sending and receiving
2767 routines. The server.[ch] now includes everything else including
2768 actual packet processing (writing and reading data) and other
2771 Renamed silc_server_private_message_send_internal to
2772 silc_server_send_private_message. The routine is still though
2773 used only to relay private messages as server does not send
2774 private messages itself.
2776 Renamed silc_server_new_channel to silc_server_create_new_channel
2777 and added new function sicl_server_new_channel that handles the
2778 incoming New Channel packet. Added also new sending function
2779 silc_server_send_new_channel to send New Channel Payload.
2781 * Added new function silc_server_notify to process incoming notify
2782 packet to the server/router. Server may then relay the notify
2783 to clients if needed.
2785 * Added new function silc_server_new_channel_user to process incoming
2786 New Channel User packet. Router will redistribute the packet and
2787 send JOIN notify to its local clients and locally connected servers
2788 if needed. Normal server will send JOIN notify to its local client
2789 on same channel when received this packet. Added also corresponding
2790 sending function silc_server_send_new_channel_user to sent the
2793 * Added boolean route argument to send_notif_to_channel and
2794 packet_send_to_channel functions to attempt to route the packet
2795 if it is TRUE and send only locally if it is FALSE.
2797 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * silc_server_replace_id now broadcasts the received replace ID
2800 packet if it is not broadcast packet already. The router must
2801 broadcast to inform other routers about changed ID.
2803 * Added backpointer to server's router into SilcServer context in
2804 silcd/server_internal.h.
2806 * Fixed silc_server_packet_broadcast to send correct broadcast
2809 * The channel key is now distributed to the local client as soon
2810 as it is received from the router (in router environment) so that
2811 no other packet may be sent for the channel until client has
2814 * silc_server_remove_channel_user now broadcasts the received
2815 Remove Channel User packet if it is not broadcast packet already.
2816 The router must broadcast to inform other routers about removed
2819 * Added users field into SilcPacketContext that is a reference count
2820 of the context. One can increase the reference count by calling
2821 silc_packet_context_dup which is now changed to just increase the
2822 reference count instead of duplicating the data. The reference
2823 count is decresed by calling silc_packet_context_free that will
2824 free the data after the reference count hits zero.
2826 For now on the packet context and everything allocated into it
2827 (including the raw packet from network) must be freed by calling
2828 the new silc_packet_context_free function. Added also new function
2829 silc_packet_context_alloc that must be used now to allocate the
2830 context. This also means that if a routine is asynchronous from
2831 silc_[client/server]_packet_parse_type the packet context must
2832 be duplicated by calling silc_packet_context_dup. Otherwise it
2833 gets free'd after silc_[client/server]_packet_parse_type returns.
2834 Also, one must remember that if packet is duplicated then its
2835 reference count must be decresed by calling the free function as
2836 many times as it was duplicated.
2838 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2839 from both client and server.
2841 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * Made joining to a channel working in router environment.
2845 * Cleaned up JOIN command on server side and create function
2846 silc_server_command_join_channel internal routine to make the
2849 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2851 * Changed silc_command_pending list to SilcDList. Also, added
2852 `ident' field to SilcServerCommandPending structure to identify
2853 the reply and to call correct callback.
2855 Added silc_server_command_pending_check function to replace the
2856 corresnponding macro. The silc_command_pending list is not
2859 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2860 to set identifier to previously allocated Command Payload. It
2861 is used to set identifier for command when resending Command
2864 * Added silc_command_payload_encode_payload to encode Command
2865 Payload buffer from SilcCommandPayload structure.
2867 * Added silc_argument_payload_encode_payload to encode Argument
2868 payload buffer from SilcArgumentPayload structure.
2870 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Changed WHOIS command to support router connection on server side.
2873 The whois request is always sent to router unless the server is
2874 standalone server. After server has received the reply from the
2875 router will it send the reply to the client.
2877 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2878 broadcast received broadcast packet. The function is used only
2879 by router. The broadcast packet is always sent to the router's
2882 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2883 render given ID to printable string, for log files for example.
2885 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2887 * Made basic router to router connections working. At least they
2888 can now connect to each other but nothing really works the way
2889 they are supposed - yet.
2891 * Added new initiator token to RouterConnection configuration
2892 file in silcd/serverconfig.[ch]. It is used to tell whether we
2893 are the initiator to the remote router or whether we'll expect
2894 the other end to connect.
2896 * Moved registering of listener task to silc_server_init, hence
2897 the server starts listenning as soon as it is run, even if it
2898 does not have connections to other routers. Let's see how well
2901 * Changed default connection retry timeouts for more suitable in
2904 * Removed cipher and such arguments from silc_idlist_add_client
2905 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2906 Added new function silc_idlist_add_data to add the keys and stuff
2909 * Added SilcIDListData structure and added it to SilcClientEntry
2910 and SilcServerEntry as their first field in the structure. This
2911 way we can explicitly cast the ID entries to the SilcIDListData
2912 structure and get common data for the entries. In past, we had
2913 to first check what type of connection it is and then cast it to
2914 correct ID entry type. Now, we can directly cast the opaque
2915 pointer to the SilcIDListData (no matter what ID entry it actually
2916 is) and get the data needed.
2918 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2920 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2921 in some circumstances even if threre were timeout tasks, though not
2922 IO tasks, but tasks anyway. Now fixed.
2924 * Defined SilcServerConnection structure to hold connection specific
2925 stuff about directly connected servers and routers. The definition
2926 is currently in silcd/server_internal.h. I thought about having
2927 a bit more important role fro this struct but for now it is used
2928 only when connecting to other server (or router actually).
2930 * Added connecting retry support in server when connecting to
2931 router(s). The retry feature implement exponential backoff
2932 algorithm. Also, added SilcServerParams structure to hold default
2933 parameters for server. For now, it include these retry settings
2934 and are hard coded. After server is moded to be as Silc Server
2935 Library this structure will be more important.
2937 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2939 * Changed client librarys channel->clients table to SilcList and
2940 changed code accordingly.
2942 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2944 * Changed client's channel table to SilcList and changed code
2945 accordingly. Also changed SilcChannelClientEntry to include back-
2946 pointer to the channel so that client entry can use that structure
2947 as list as well and we have fast cross-reference to the channel.
2948 This change dramatically decreased the complexity of channel
2949 handling with client entry and vice versa (removed one extra
2950 loop when searching for channel entry from many functions).
2952 * Changed server->sim from table to SilcDList and changed code
2955 * NAMES command can now be used from user interface. It will show
2956 the user list on the channel, neatly.
2958 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2959 Code now saves realname of the user if it becomes available.
2961 * Renamed configure.in to configure.in.pre and made ./prepare
2962 script to automatically add correct version string to
2963 configure.in which it creates from configure.in.pre.
2965 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * NAMES command reply now shows users mode with the nickname when
2970 * Moved silc_client_ch[u]mode[_char] functions from
2971 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2972 place sucks, they are utility functions and should be in some
2975 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2977 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2980 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Added TRQ (efficient deque and list library) into lib/trq. This is
2985 a very good list library that is currently used in the SILC. Defined
2986 SilcList API over the library because I didn't like the API very
2987 much. See lib/trq/silclist.h for the API and examples of how to
2988 use the API. Fixed various places in the code to use the new
2989 SilcList API. The SilcList is meant for lists that has a structure
2990 already defined as a list. It is not suitable to add just some
2991 context to the list (in TRQ, the context is the list actually).
2993 So, I defined SilcDList that can be used for the purpose where
2994 predefined list structure does not exit. This can be used as
2995 such list. Now some context just can be added to the SilcDList.
2996 Currently this list is not used in the SILC just yet, though there
2997 are a lot places where this can replace dynamically allocated
2998 tables and I will fix these places, later, to use SilcDList.
2999 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3000 and use TRQ internally).
3002 Also fixed some annoying warning messages that the original TRQ
3003 code generated. Also minor changes to TRQ's Makefile.in.
3005 * Added support for querying by Client ID to both WHOIS and
3006 IDENTIFY commands into server, as required by the protocol.
3008 * Removed method function pointers from SilcBuffer structure. They
3009 weren't used to anything and just increased the context size for
3010 no good reason. This change also made silc_buffer_alloc and
3011 silc_buffer_free functions inline functions.
3013 * Disabled command flooding detection support until it's fixed so
3014 that it accepts commands in but does not execute them more than once
3017 * Added silc_net_localhost(), to return local hostname, into
3018 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3019 that must be initialized before calling silc_client_init.
3021 * Added new function: silc_server_send_notify_on_channels to send
3022 notify messages to all channels client has joined. It is assured
3023 that the message is sent only once per client.
3025 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3026 lib/silcutil/silcutil.[ch] as silc_format function. The new
3027 function is generic and is used by server as well, not only by
3028 the logging routines.
3030 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3031 the provided version string was not acceptable. Added new function:
3032 silc_ske_check_version into lib/silcske/silcske.h. The function
3033 must be implemented by the application (client or server) and it
3034 does not reside in the SKE library. The function checks the version
3035 string remote end sent.
3037 * Added back pointers (to opaque context and to SilcSocketConnection)
3038 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3040 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3041 duplicate packet context structure.
3043 * Changed `notify' client operation to send same arguments as client
3044 receives from server except for ID's. ID's are mapped to correct
3045 ID entry and that is returned. Also, if channel entry is not sent
3046 by server but the notify is for channel the channel entry is sent
3047 to application (otherwise application doesn't know that it is for
3048 channel (library gets it from packet's Destination ID)).
3050 * Added silc_client_remove_from_channels into client library to
3051 remove a client from all channels it has joined to. Used when
3052 received SIGNOFF notify from server. Added also new function
3053 silc_client_replace_from_channels to replace old ID entry with
3054 new ID entry on all channels. Used when received NICK_CHANGE
3057 * Fixed ID Cache list handling in silc_idlist_get_client in
3058 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3059 to get (or query) client by ID.
3061 * Updated TODO list.
3063 * Added connection authentication status message defined by the
3064 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3065 support for these into the code in client and server side.
3067 * Added generic function silc_client_send_command to send any command
3068 with variable argument list. Application should use this function
3069 to send commands if the command functions provided by the library
3070 does not suite for the application's user interface needs.
3072 * Added new `failure' client operation. Application is notified about
3073 received failure packet if client is executing a protocol. In this
3074 case the protocol's execution has failed.
3076 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3077 is required by the protocol.
3079 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3080 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3083 * Added status flag to SilcSKE object to indicate realtime status
3084 of the SKE protocol.
3086 * Application receives now exactly same command reply arguments as
3087 the library receives from server. However, if ID is received the
3088 corresponding ID entry is returned to the application (eg. Client
3089 ID is mapped to correct SilcClientEntry entry and that is returned).
3090 Changed command_reply client operation due to this change.
3092 * Changed all ID's in commands and in command replys as ID Payloads.
3093 Change affected both client and server side codes.
3095 All ID's sent in SILC network (with execption of ID's in SILC
3096 Packet header) are sent in ID Payload to support variable length
3099 * Server now notifies nick changes and notifies all clients on
3100 the channels about the new nickname (about the new Client ID,
3103 * Implemented CMODE command to change channel modes. Supports all
3104 channel modes defined by the protocol specs except ban and invite
3105 lists. (Also, private channel key mode is supported but support for
3106 setting private channel key in client is missing, thus, this mode
3107 has no effect on client side (except that server requires that the
3108 client uses private channel key and normal channel traffic does not
3111 Also, invite mode works per se, but INVITE command does not work
3112 yet correctly, so you can set channel as invite only channel but
3113 inviting clients to the channel does not work (it is yet to be
3114 thought what's the best way to do it).
3116 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3117 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3118 Implemented CUMODE command to change user's mode on the channel.
3119 Supports all modes defined by the protocol specs.
3121 * Added NAMES command reply to return users modes on the channel.
3123 * Removed unnecessary and slow ciphers from lib/silccrypt.
3125 * Set SO_KEEPALIVE option to connection sockets by default.
3127 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3129 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3130 redefined the Notify Payload into protocol specs.
3132 * Added silc_id_payload_parse_id to get ID directly from raw
3135 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3138 accept searching by Client ID as well.
3140 * Added support for LEAVE and SIGNOFF notify types in client library.
3142 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3143 to parse ID Payload from raw data.
3145 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Added flags parameter into silc_ske_assemble_security_properties
3148 function in lib/silcske/silcske.[ch].
3150 * Changed notify client operation to fit better for notify messages
3151 sent by server. The notify payload received from server is now
3152 passed to the application (after parsing it to SilcNotifyPayload).
3153 It is application's responsibility to retrieve the arguments
3154 from the payload and show the message the way it wants. The message
3155 sent by server is implementation specific.
3157 * Changed public keys to comply with the protocol specification.
3158 Old public keys are not supported anymore and are not compatible.
3160 * Removed nickname from Channel Payload as the latest draft removed
3161 it. The client must resolve the nickname from the NAMES command
3162 reply received when it joined the channel.
3164 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3166 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Fixed some errors in protocol specification drafts.
3170 * Created lib/silccore/silcnotify.c to implement Notify Payload
3171 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3172 generic payloads described by protocol specifications. The file
3173 includes implementations for ID Payload and Argument Payload.
3175 * Changed Command Payload implementation to use the new Argument
3176 Payload. Changed command_xxxx_payload to command_payload_xxxx
3177 to comply with SILC coding conventions.
3179 * Added suppport for Argument Payload handling in Notify Payload
3180 implementation as protocol requires it. Added the new support
3181 into server and client lib as well.
3183 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3185 * Added support for multiple nicknames on same channel. [n] is
3186 added locally to the nickname if there are more than one same
3187 nicknames on the channel.
3189 * Server now sends all nicknames that matched WHOIS request.
3190 Client also shows the list received from server.
3192 * Added TOPIC command to client side. User can now set and show
3193 current topic on channel.
3195 * Added MOTD command to client and server. Also, server sends the
3196 motd when client connects to the server.
3198 * Changed version strings to comply ISO 8601.
3200 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3202 * Fixed protocol error handling in client library. It should now
3203 cope even if the SKE fails for some reason.
3205 * Made new protocol specification drafts for submitting to IETF.
3207 * Implemented TOPIC command to server in silcd/command.c.
3209 * Added two new notify types into lib/silccore/silcnotify.h:
3210 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3211 notify nickname change and topic setting/change on a channel.
3213 * API change of command_reply operation in client library. The
3214 application gets now the status type received from server as well.
3216 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3220 * Cras fixed and optimized the packet handling even further and
3221 it should work now. Minor change to the prototype of function
3222 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3224 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3226 * Added new function into lib/silcutil/silcschedule.[ch]:
3227 silc_schedule_with_fd to select() a specified fd. The function
3228 returns after timeout expires or data arrives or goes. The
3229 function is used by packet routines to wait that all data is
3230 received from network.
3232 * Fixed data reading from network in lib/silccore/silcpacket.c.
3233 The code now assures that all data is read from the fd and then
3234 continues packet processing. This was a bug fix since the code
3235 used to drop some data in some circumstances.
3237 * Added new function into lib/silcclient/client.[ch]:
3238 silc_client_start_key_exchange to start key exchange after
3239 connection has been established to server. The code internally
3240 now uses this funtion but its main purpose was to provide it
3241 for applications that perform their own connecting. After
3242 application has created a connection it merely calls this
3243 function to start the key exchange between client and server.
3244 The library takes care of everything else after that.
3246 Updated also lib/silcclient/README to explain the usage of
3249 * Do not send to application information that connection has
3250 been established. Application gets notified it by connect
3253 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3255 * Applied cras's patch to add silc_schedule_one function. The
3256 function runs scheduler once and returns.
3258 * Fixed the scheduler after cras messed it up. The timeout
3259 handling works now as it's supposed to work.
3261 * Added into lib/silccore/ silcnotify.h to include notify
3262 message types support. Changed silc_server_send_notify*
3263 functions, in server.[ch], to support those new notify types.
3264 Added the support for the notify types into client library,
3265 as well. Added new notify client operation into ops.h in
3268 * Changed silc_server_packet_send_to_channel to send normal
3269 packets instead of just channel message packets. The function
3270 is now used to send the notify packets to channels. It is not
3271 used to send channel message packets anymore, as server never
3274 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3275 va_arg()s as it seems to require it nowadays. I guess, if SILC
3276 is compiled with older va_arg() the new code should work anyway.
3278 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Splitted core library. Core library (lib/silccore) includes
3281 now only SILC protocol specific core (and common) components.
3282 Created new utility library (lib/silcutil) that includes more
3283 generic purpose stuff. The stuff for util library was taken
3284 from the old core library. This was minor and easy split.
3286 * Created SILC Client Library (lib/silcclient) that includes
3287 implementation of the SILC client without user interface. This
3288 was major move from silc/ directory. The code has been changed
3289 so that it is transparent towards the user interface. The
3290 silc/ directory includes now the same user interface as before
3291 and it uses the new client library. Read lib/silcclient/README.
3292 Basicly, the client library performs everything else related
3293 to SILC except user interface handling. Also, configuration
3294 files are considered to be part of user interface and library
3295 does not handle them.
3297 This change also changed a lot of structures, function naming etc.
3298 Most important change was that SilcClientWindow object was
3299 renamed to SilcClientConnection in the client library. Created
3300 also new file lib/silcclient/ops.h. Also added new files
3301 silc/local_command.[ch] and silc/client_ops.[ch].
3303 All these changes were made to make it easier for user interface
3304 designers to create what ever user interface for the SILC client
3307 It is also expected that the server will be moved to lib
3308 directory as well and SILC Server Library will be created;
3309 sometimes in the future.
3311 * Removed Local commands from lib/silccore/silccommand.h as
3312 they are application specific and new client library does not
3313 handle any of those anymore.
3315 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3316 old client implementation in silc/.
3318 * Added support for callback functions in SILC_LOG_* macros.
3319 Application can now set its own callbacks that will be called
3320 instead of using the default functions that will always print
3321 the debug messages to stderr (or stdout). Also, debugging can
3322 now be disabled by setting silc_debug to FALSE and re-enabled by
3323 setting it to TRUE. Note, that logging will still work even
3324 if debugging is disabled.
3326 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3327 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3328 silc_log_reset_debug_callbacks.
3330 * To enable debugging in silc client one must give now -d
3331 option on command line.
3333 * Changed silc_schedule_init to automatically allocate task queues
3334 if they are not allocated before calling it.
3336 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3338 * Added GMP 3.1 into math library.
3340 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3343 a channel in SILC network. The packet is used by servers and
3344 routers to notify other routers that user has left a channel.
3345 This little feature was missing until now. Added the feature
3346 to protocol specification as well.
3348 Added functions: silc_server_send_remove_channel_user and
3349 silc_server_remove_channel_user into server.[ch].
3351 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3352 lib/silccore/silcpacket.h. However, they are not implemented
3355 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Fixed joining to a channel and sending channel messages
3358 between server and router. The channel message sending should
3359 now work inside a cell.
3361 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Fixed the private message sending between server and router.
3364 The private message sending should now work inside a cell.
3366 * Added silc_server_replace_id into server.[ch] to replace
3367 existing ID in the SILC network.
3369 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3370 and silc_idlist_replace_server_id into idlist.[ch] in server.
3372 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3374 * Fixed the server to server connections. Server can again now
3375 connect to router. Router to router connections probably does
3378 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Added dynamic protocol registering support. Now protocols can
3381 registered and unregistered on the fly. Patch by cras.
3383 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * Added lib/contrib directory to hold routines that some platforms
3386 don't have but are needed by SILC.
3388 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3389 into lin/contrib to provide getopt() and getopt_long() for
3390 those who don't have it.
3392 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3394 * Added AWAY command to client. When away message is set and
3395 client receives a private message packet the client automatically
3396 replies to the sender with the away message.
3398 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3399 bug seemed to be the cause of recent problems when compiling
3402 * Added version detection support to SKE protocol specification
3403 and added the new changes to the SKE implementation as well.
3404 There were other minor changes in the SKE protocol as well.
3406 Many changes in lib/silcske/silcske.[ch] and in
3407 lib/silcske/payload.[ch].
3409 * Added ^U functionality, clear input line. Patch from cras.
3411 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3413 * Mainly small bugfixes on core library. Fixed some debugging
3414 logging and buffer overflow in silclog.c.
3416 * Updated config.sub and config.guess on the distribution tree.
3418 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3420 * Added command lagging support in server. Client may execute
3421 commands now only once in two seconds.
3423 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3425 * Optimized packet reception. MAC computation and checking is now
3426 also more optimized. A lot previously duplicated code is now
3427 used as generic by both client and server.
3429 * Fixed key pair generation in clientutil.c
3431 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3433 * Added into lib/silccore/silcbufutil.[ch] new function;
3434 silc_buffer_realloc.
3436 * Moved generic packet sending/encryption functions to
3437 lib/silccore/silcpacket.[ch] from client and server. Some
3438 rewriting of the functions.
3440 * Moved all generic packet reception/decryption functions to
3441 lib/silccore/silcpacket.[ch] from client and server. The
3442 packet processing is now much cleaner in both client and server.
3443 These were major changes in both client and server.
3445 * Created many common functions in server to do packet sending.
3446 Previously code were duplicated a lot, this has been removed
3449 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3451 * Rewrote major parts of the ID cache system. Don't know
3452 whether it is better now or not but at least the API is more
3455 * Major rewrite on ID cache stuff on client because of the ID
3456 cache API changes. Added idlist.c to client.
3458 * Also major rewrite on ID cache stuff on server as well.
3459 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3460 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3461 in hand, instead they are all put into the ID cache system now.
3462 All server_idlist_* routines uses ID cache now instead of
3463 traversing its own lists (those lists does not exist anymore).
3464 SilcIDList though still exists. Also, SilcXXXEntry's are
3467 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3469 * Finally made the SKE implementation compliant to the protocol
3470 specification. All mp integers are now binary encoded as
3471 opposed being HEX encoded.
3473 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3476 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3477 functions: silc_[encode/decode]_pem. Also added function
3478 silc_encode_pem_file to PEM encode with newlines ('\n') for
3481 * SILC public keys are now encoded either PEM or binary. Same
3482 option is for private keys as well. By default private keys
3483 are binary encoded and public keys PEM encoded. Silly HEX
3484 encoding were removed.
3486 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3487 function to create fingerprints.
3489 * Fixed a bug in SHA1; does not change the original data anymore.
3491 * Partly implemented INFO command on client and server side.
3492 Fixed CLEAR command. Changes to SERVER command; show current
3493 server(s) when giving command without arguments. Added
3494 VERSION command to client.
3496 * Added check to server that unregistered connections cannot
3497 execute commands (unless it is specificly allowed).
3499 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Fixed screen refresh.
3503 * Fixed channel joining bug from client. On some circumstances
3504 client tried to join to a channel it had already joined.
3506 * Added public key verification process into client's protocol.c.
3507 The client now verifies the public key from user and saves
3508 it into ~./silc/serverkeys/ directory.
3510 Added into: clientutil.[ch]: silc_client_verify_server_key.
3512 * Changed SKE protocol's silc_ske_initiator_finish function
3513 to accept callback function that verifies the received public
3514 key. Removed old silc_ske_verify_public_key function.
3516 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3519 silc_pkcs_private_key[_data]_set.
3521 * Made the password and public authentication more cleaner in
3522 server's protocol.c.
3524 * Removed historic and obsolete protocol `channel_auth' from
3525 both client and server.
3527 * Removed wrong way of sending command status messages from
3528 server to client in server's command.c. The old way violated
3529 protocol specification.
3531 Changes to silccore/silccommand.[ch]: removed
3532 silc_command_encode_status_payload -> not needed anymore,
3533 changed silc_command_encode_payload_va to accept extra
3534 argument on variable argument list. The argument type must
3535 now be provided to the function. Also, added new function:
3536 silc_command_encode_reply_payload_va which is same as
3537 normal command_encode_payload_va except command status type
3538 is provided as extra argument.
3540 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Added ~./silc directory handling. The directory includes the
3543 public and private keys for the client.
3545 Added silc_client_check_silc_dir, silc_client_create_identifier
3546 and silc_client_load_keys.
3548 * Implemented SILC protocol compliant public key. Added public
3549 and private key saving to and loading from files.
3551 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3552 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3553 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3554 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3555 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3557 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3558 silc_pkcs_load_[public/private]_key.
3560 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3562 * Added silc_server_get_route (route.[ch]) to get connection
3563 data for the fastest route for given ID.
3565 * Implemented INVITE command on client and server. The command
3566 were re-defined in the SILC Protocol Specification and the
3567 implementation now complies with the specification.
3569 * Implemented PING command on client and server.
3571 * Implemented NAMES command on client and server. The server side
3572 supports currently only normal server not router server yet.
3573 Some changes to NAMES definition in SILC protocol specification.
3575 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Implemented LEAVE command on client and server.
3579 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3580 again. This change was made to the protocol as well. Server
3581 should not violate the protocol specification anymore.
3583 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3586 was tested. SOCKS4 was not but should work anyway.
