1 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed a va_arg in silc/client_ops.c.
5 * Oops, RC5 routines were named AES and caused some problems
6 when not using SIM's. Affected file lib/silccrypt/rc5.c.
8 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
10 * Added new SilcIDIP structure into the lib/silccore/id.h and
11 replaced the old `ip' fields from all SILC ID's to that type.
12 This is a step towards IPv6 support.
14 The silc_id_get_len takes now the ID as an extra argument.
15 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
16 both IPv4 and IPv6 based ID's.
18 The affected files are lib/silccore/id.[ch] and other files
19 around the tree using these routines.
21 * Removed the ID length arguments in server from various
22 silc_server_send_notify_* routines -> they are not needed
25 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
27 * Fixed memory leak in silc_encode_pem_file in the file
28 lib/silcutil/silcutil.c.
30 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
32 * Check minor version as well in the SKE. Affected files are
33 silcd/protocol.c and lib/silcclient/protocol.c.
35 * Added --identifier option to the server so that an identifier
36 can be when creating the public key for the server. Affected
37 file is silcd/silcd.c.
39 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
40 lib/silccrypt/silcpkcs.c.
42 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
44 * Register default ciphers and stuff when using -C option with
45 the server. Affected file sildc/silcd.c.
47 * Put back the servers public key filename format, it is better
48 than the new one. For now, the client keys are saved with the
49 new filename format. The affected file silc/client_ops.c.
51 * Implemented the Cipher API for the rest of the ciphers that
52 did not implement it or implemented it the wrong way.
54 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
56 * Register default ciphers and stuff when using the -S option
57 in the client. Affected file silc/silc.c. Same also when
58 creating new key pair with -C option.
60 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
62 * Fixed the silc_verify_public_key client operation function to
63 save the public keys differently. The fingerprint is now
64 used as filename and not the hostname. This way also the
65 client keys are saved uniquely and not with hostnames. The
66 affected file is silc/client_ops.c.
68 * Trimmed the silc_hash_fingerprint function to remove extra
69 whitespaces from the end of the fingerprint. The affected
70 file is lib/silccrypt/silchash.c.
74 * Added silc_cipher_register_default function to register all
75 default ciphers. It can be used when configuration files
76 does not exist and the application does not want any specific
77 ciphers in any specific order.
79 The SilcDList is now used as silc_cipher_list dynamically
80 allocated cipher list. Removed the static list all together
81 and now all ciphers must be allocated to the dynamic list.
82 The silc_cipher_alloc routine was changed to check only the
85 All silc_cipher_* routines that used to return int returns
88 The affected files lib/silccrypt/silccrypt.[ch].
90 * The same thing was done to silc_hash_* as for silc_cipher_*
91 routines. Affected files lib/silccrypt/silchash.[ch].
93 * The same thing was done to silc_pkcs_* as for silc_cipher_*
94 routines. Affected files lib/silccrypt/silcpkcs.[ch].
95 Added also silc_pkcs_[un]register[_default] functions.
96 Removed the data_context from the PKCS API.
98 * Added silc_hmac_register_default function to register default
99 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
100 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
101 to unregister all hmacs at once.
103 * Register the default ciphers, hash functions, PKCSs and HMACs
104 if client's configuration file does not exist. The affected
107 * The client did not load the hash functions from the SIM
108 modules at all. Added support for this. Affected file is
111 * When decoding public key with silc_pkcs_public_key_decode, check
112 the supported algorithm only if PKCS are registered. Affected
113 file lib/silccrypt/silcpkcs.c. The same was done with the
114 silc_pkcs_private_key_decode.
116 * Fixed the SILC List routines to keep the list always in order.
117 It used to change the list's order when traversing the list but
118 not it preserves the order. Affected file lib/trq/silclist.h.
120 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
122 * Added the client library to use the SilcSocketConnection's
123 reference counter (by silc_socket_dup) to prevent the bug that
124 the socket object may be freed underneath async operation.
126 * The name resolv library checking fixes in the configure.in.pre.
129 * Created new version of the protocol drafts for future
130 development. The -03 drafts are the ones that will be changed
131 in the trunk now and the -02 will remain as they are.
133 * Send list of CUMODE notifys to the router when announcing
134 the channel users to the router. Affected file silcd/server.c.
135 If the router receiving channel founder CUMODE for a channel
136 that already has channel founder it will send CUMODE notify
137 to the sender to remove the channel founder rights from the
138 announced client. Affected file silcd/packet_receive.c.
140 * The CUMODE notify may now use Server ID as well as the entity
141 who changes the mode. Updated protocool specs.
143 * Updated INSTALL and README files.
145 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
147 * New web pages in the http://silc.pspt.fi. The pages was
152 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
154 * Implemented the [DenyConnectin] config section in the server.
155 Added silc_server_config_denied_conn to check whether incoming
156 connection is denied. Affected file silcd/serverconfig.[ch].
158 * Do not check the ports when checking the incoming configuration
159 data if the port is 0, meaning any. Affected file is
160 silcd/serverconfig.c.
162 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
164 * Fixed buffer overflow in silc_string_compare in the file
165 lib/silcutil/silcutil.c.
167 * Fixed double free in silc_server_command_leave in the file
170 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
172 * Fixed the version checking in the server. Affected file is
175 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
177 * Fixed the configuration data fetching when accepting new
178 connections in the server. Affected file silcd/server.c.
180 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
182 * Added `sender_entry' argument to the function
183 silc_server_packet_relay_to_channel so that we can check
184 whether some destination actually belongs to the same route
185 the sender belongs (ie, we must not resend the packet to the
186 sender). Affected file silcd/packet_send.[ch].
188 * Added `servername' field to the SilcClientEntry in the server
189 to hold the name of the server where client is from. Affected
190 file is silcd/idlist.h.
192 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
194 * Moved the channel message encrypting in the router betwen
195 router connections from silc_server_channel_message to the
196 silc_server_packet_relay_to_channel since we want to check
197 whether we have anybody channel before encrypting anything.
198 Affected files silcd/packet_[receive/send].c.
200 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
202 * Fixed the [AdminConnection] server config section to support
203 multiple entries. Affected file silcd/serverconfig.c.
205 * Added support into the server to check the validity of the
206 incoming connection before executing any KE or authentication
209 * The connection configuration is now saved to the KE and
210 connection auth protocol contexts and not fetched anymore in
211 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
213 * The local hosts listenning address and port is also resolved
214 now when starting the server. We want to have the socket object
215 to include the real address and port for the listener. Added
216 new function silc_net_check_local_by_sock into the files
217 lib/silcutil/silcnet.[ch].
219 * Fixed a broadcast bug in server -> do not broadcast if we
222 * Fixed a routing bug. Do not route broadcast packets ever.
223 Broadcast packets must be processed always and not routed since
224 they may be destined to some other host than yourself and thus
225 would get routed without no good reason. Affected file is
228 * Added function silc_server_config_is_primary_route to check
229 whether primary router connection has been configured (a router
230 configuration that we are initiating). If there is not, we
231 will assume that there is only two routers in the SILC network
232 and we will use the incoming router connection as our primary
233 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
235 * Changed the order of the broadcasting. Broadcast _after_ the
236 packet has been processed not before. Affected file is
239 * Fixed a [ClientConnection] parsing bug. The port was never
240 parsed correctly thus resulting to port 0. Affected file
241 silcd/serverconfig.c.
243 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
244 argument and did not set the broadcast packet flag. Affected
245 file silcd/packet_send.c. Fixed same bug in the function
246 silc_server_send_notify as well.
248 * If we receive NEW_ID packet for our own ID in the server, ignore
251 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
255 * Removed the nickname from the Private Message Payload.
256 Updated the code and the protocol specs.
258 * Updated protocol specs for submitting to the IETF.
260 * Tweaked the Random Number Generator a bit. Affected file
261 lib/silccrypt/silcrng.c. Exported a new function
262 silc_rng_[global]_add_noise which can be used to add more
265 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
267 * Do not parse packets with different timeout when protocol
268 is active -> may cause problem with rekey. Affected file
271 * When server receives signoff notify it must not create
272 new channel key if the client is on any channels since the
273 sender of the signoff notify will create it.
275 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * Added printing of error messages during SKE protocol from the
278 failure packet sent by server during SKE. Affected file
281 * Removed the client's failure_callback handling with timeout
282 and handle it immediately when received.
284 * The SKE library returned wrong type in SUCCESS and FAILURE
285 packets. They must be 32 bit MSB not 16 bit MSB.
287 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
289 * Ok, rewrote the logic of the re-key and now it seems to work.
290 I tested it on high traffic with frequent re-keys without
291 problems. Added hmac_receive (and renamed hmac to hmac_send)
292 in SilcClientConnection in lib/silcclient/client.h and
293 in SilcIDListData in silcd/idlist.h. Also, removed the
294 SilcPacketParserContext's cipher and hmac fields as they are
295 not needed anymore and actually caused some problems when
296 the ciphers and hmac's changed underneath the packet parser.
298 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
300 * If re-key protocol is active then process the incoming packets
301 synchronously since we must assure that icoming packets encrypted
302 with the old key is processed before the new keys is set to
303 use. This is true other packets than for REKEY packets.
304 Affected file silcd/server.c. The same was done to client library
305 as well, affected file lib/silcclient/client.c.
307 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
309 * Fixed bug in client and server to accept the force send if
310 the packet is send from silc_[server/client]_packet_process
311 function. Otherwise the packets are never delivered, oops.
313 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
315 * Disable force sending of packets when REKEY protocol is active.
316 We must assure that no packet is sent directly when rekey is
317 performed. All packets must be sent through packet queue.
318 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
319 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
320 function is silc_[server/client]_packet_send_real to check
323 * Replaced the SIM paths from example config files to
324 /usr/local/modules. Also, make install creates now
325 /usr/local/silc/logs directory to hold all the SILC server
328 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
330 * Made the configure.in.pre work on Solaris. Patch by salo.
332 * Made all ciphers compatible with non-x86 machines. Defined
333 CBC mode macros into lib/silccrypt/ciphers_def.h.
335 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
337 * Fixed the make install.
339 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * When MAC computation fails the silc_packet_decrypt returned 0
342 even though it was supposed to return -1. Fixed this. The
343 affected file is lib/silccore/silcpacket.c.
345 * Do not replace the config files in /etc/silc (in make install)
346 if they already exist. Affected file ./Makefile.am.
348 * Do not send re-key packets immediately but through packet queue.
349 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
351 * Changed silc_net_check_host_by_sock to return FALSE if the
352 IP/DNS could not be resolved. Though, it returns the IP address
353 now even if it could not resolve it (but returns also FALSE).
354 Affected file lib/silcutil/silcnet.[ch].
356 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * Added silc_pkcs_decode_identifier to decode the public key's
359 identifier. Affected file lib/silccrypt/silpkcs.[ch].
360 Added also silc_pkcs_free_identifier. Added also new context
361 SilcPublicKeyIdentifier.
363 * Added -S option to the silc client. It is used to dump the
364 contents of the specified public key file.
366 * Changed the PKCS api to return the public key length when
367 setting the public key.
369 * Fixed a fatal bug in the public and private key file loading.
370 Affected file lib/silccrypt/silcpkcs.c.
372 * Execute the packet parsing for client with zero (0) timeout
373 if the protocol is active. Affected file silcd/server.c.
375 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
377 * Made the key generation options to the silcd program. Added
378 -C option, equivalent to client's option.
380 * Added new [ServerKeys] config section to the server. It
381 configures the server's public and private key.
383 * Defined generic Public Key Payload into the protocol
384 specification to send specific type of public keys and
387 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
388 public key or certificate.
390 * Implemented the GETKEY command to the server and to the
391 client library and on user interface.
393 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
395 * Made preliminary `make install' work.
397 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
399 * Added SilcServerRekey context into silcd/idlist.h.
401 * Added the PFS support as defined in the specification to the
402 SKE protocol. Affected files lib/silcske/*.c.
404 * Added `ske_group' field to the SilcServerRekey context to hold
405 the number of the SKE group that is used with PFS in re-key.
406 Affected file silcd/idlist.h.
408 * Added PFS re-key support to the server. Affected file is
411 * Added silc_protocol_cancel to cancel execution of the next
412 state of the protocol. Affected file is
413 lib/silccore/silcprotocol.[ch].
415 * Added the re-key support with and without PFS to the client
416 library. Re-key is performed once in an hour, by default.
418 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
419 Added silc_client_rekey_callback and silc_client_rekey_final.
420 Affected files are lib/silcclient/protocol.[ch] and
421 lib/silcclient/client.[ch].
423 * Removed the `hmac_key' and `hmac_key_len' fields from the
424 SilcClientConnection structure; not needed. Affected file is
425 lib/silcclient/client.h.
429 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
431 * Do not ask whether user wants to use the negotiated private key
432 for private messages, just use it. Affected file is
433 silc/local_command.c.
435 * Added `send_enc_key' and `enc_key_len' fields to the
436 SilcIDListData structure since they are needed in the re-key
437 phase. Affected file is silcd/idlist.[ch].
439 * Implemented the simple re-key protocol into the server.
440 Affected files silcd/server.c and silcd/protocol.[ch]. The
441 re-key will be performed once in an hour, by default.
443 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
444 Added silc_server_rekey, silc_server_rekey_callback and
445 silc_server_rekey_final.
447 * Removed Tunneled flag from the protocol. Updated the code
448 and the specifications.
450 * Adde `pfs' field to the SilcIDListData to indicate whether
451 the PFS is to be performed in the re-key. Affected file is
454 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
457 int64 of at least the xintXX size. If void * is less that 4
458 bytes uint32 * will be used. Defined bool as boolean.
460 * Changed _ALL_ unsigned long and unsigned int to uint32,
461 unsgined short to uint16 in the source tree.
463 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
464 not handle clients that has entry->data.registered == FALSE.
465 They are not in the network anymore. Affected file is
468 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
470 * Implemented the sending of the SERVER_SIGNOFF notify in the
471 server. Affected file is silcd/server.c.
473 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
474 Added also silc_notify_payload_encode_args into the
475 lib/silccore/silcnotify.[ch].
477 * Implemented ther SERVER_SIGNOFF notify handling in the server.
478 Affected file silcd/packet_receive.c.
480 * Implemented the SERVER_SIGNOFF notify handling in the client
481 library. Affected file lib/silcclient/client_notify.c. Also,
482 implemnted the printing of the SERVER_SIGNOFF info to the
483 application. Affected file silc/client_ops.c.
485 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
486 if the deleting was successful. Affected file silcd/idlist.[ch].
488 * Added support for public key authentication in the connection
489 authentication protocol in the client library. Affected file
490 lib/silcclient/protocol.c.
492 * Changed the server's silc_idlist_get_clients_by_* interface
493 to support already allocated array so that new entries may be
494 added to pre-allocated array. Affected file silcd/idlist.[ch].
495 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
498 * All command reply functions in the server now calls the
499 pending command callback even if error occured. This way the
500 error will be delivered to the client as well. Affected files
501 silcd/command.c and silcd/command_reply.c.
503 * Fixed INFO command to return local server's info if no server
504 was provided. Affected file lib/silcclient/command.c.
506 * Removed RESTART command for good. Updated the code and the
509 * Rewrote parts of the task system. It is a bit simpler now.
510 Removed unsued task priorities. The affected files are
511 lib/silcutil/silctask.[ch].
513 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
515 * Moved the USERS printing from the library to the application.
516 Affected files lib/silcclient/command.c and silc/client_ops.c.
518 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
522 * Added channel key re-key support. The re-key is perfomed
523 only by the router and is done once in an hour. Added `rekey'
524 field to the SilcChannelEntry in the server. Affected files
525 silcd/server.c and silcd/idlist.h.
527 * Added silc_task_unregister_by_context into the file
528 lib/silcutil/silctask.[ch].
530 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Added SILC_UMODE_GONE mode to indicate when the client is not
533 present in the SILC network. Added also support to the local
534 command AWAY that will set this mode. Added support of showing
535 "xxx is gone" in WHOIS command. The USERS command shows the
538 * Fixed setting server and router operator privileges in the
539 server's UMODE command. Affected file silcd/command.c.
541 * Merged the SKE KE1 and KE2 payloads into one payload. The
542 new KE payload is equivalent to the old KE2 payload.
544 Cleaned up the SKE Start Payload parsing. It now uses the
545 simple buffer unformatting to do the parsing. A lot faster
548 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
549 to the SKE that is used to indicate whether both of the SKE
550 parties should perform authentication. By default only the
551 responder performs authentication. By setting this flag also
552 the initiator must do authentication. By default it is unset
553 since in normal SKE case, client to server connection, only
554 the responder should do authentication. When doing SKE between
555 two clients both should perform authentication. Updated the
556 code and the protocol specs.
558 * A little fix to IDENTIFY command in the server. Search the
559 client first by hash not nickname. Affected file is
562 * Fixed the silc_client_close_connection to support closing
563 the client to client connections wihtout deleting too much
564 data. Affected file lib/silcclient/client.c.
566 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
567 are received if protocol used to be active but is not anymore
568 the application would crash due to NULL pointer dereference.
569 Affected files silcd/server.c and lib/silcclient/client.c.
571 * Added `hash' field to the SilcClientConnection to include
572 the hash function negotiated in the SKE protocol.
574 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
575 to set the channel founder authentication data. A client can
576 claim the founder rights later by providing the authentication
577 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
578 This way the channel founder can regain the channel founder
579 privileges even it is left the channel. This works only on
580 local server and the client must be connected to the same
581 server to be able to regain the founder rights. Updated the
582 protocol specs accordingly.
584 Added support to the CMODE command in the client to set the
585 founder auth data. Read the README to see how to set it.
587 Added support to the CUMODE command to claim the founder
588 rights. Read the README to see how to do it.
590 Added support for the founder authentication to the Channel
591 Entry in the server. Affected file silcd/idlist.h.
593 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
594 server's CMODE command. Affected file silcd/command.c.
596 * Added the following new functions into lib/silccore/silcauth.[ch]:
597 silc_auth_get_method and silc_auth_get_data.
599 * The server now saves the remote hosts public key to the
600 SilcIDListData pointer. Affected file silcd/protocol.c.
602 * The normal server now does not remove the channel entry from
603 the cache if the founder authentication data is set. It used
604 to remove it if the founder was the last one on the channel on
605 the server and left the channel. The auth data is saved and
606 if the channel is re-joined later the old entry is used with
607 the old auth data. Affected files silcd/command_reply.c and
610 * Removed the `pkcs' field from the SilcIDListData structure
611 in the server; it is not used. Affected file silcd/idlist.h.
613 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
615 * Fixed packet processing on slow links. Partial packets were
616 never re-processed because the incoming data buffer was cleared
617 by the application. Application must not directly clear the
618 sock->inbuf, the packet processing routines handle it. Fixed
619 this in client library and in server.
621 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Fixed the WHOIS and IDENTIFY send reply function to really
624 check whether to send list or just one entry. Affected file
627 * Cleaned up the LEAVE command's channel key distribution. The
628 affected file silcd/command.c.
630 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
631 can enforce the channel mode as well. In that case the ID
632 includes the ID of the server. The code now enforces the
633 mode change if the router have different mode than the server.
635 * The notify client operation with CMODE_CHANGE notify can now
636 return NULL client_entry pointer if the CMODE was not changed
637 by client. Application must check for this.
639 * Added <Server ID> argument to INFO command to support server
640 info fetching by Server ID.
642 * Added silc_server_announce_get_channel_users to get assembled
643 packets of channel users of the specified channel. Affected
644 file silcd/server.[ch].
646 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
647 was freed underneath the ID Cache.
649 * Re-announce clients when the server received CHANNEL_CHANGE
650 notify from the router. Affected file silcd/packet_send.c.
652 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
654 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
655 crashed since it did not handle the fact that there is no cipher
656 called "3" and didn't check the error condition. Now fixed.
658 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
659 flag. It can be used to send message requests.
661 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
663 * Implemented the RESTART command in the client.
665 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
666 notice type messages. Added notice printing to the user
669 * The channel keys are not re-generated if the channel's mode
670 is PRIVKEY, ie private key on the channel exists. Affected
671 files silcd/server.c and silcd/command.c.
673 * Fixed a little bug in channel message delivery when channel
674 private keys are set in the server. Affected file is
677 * Changed the setting on channel->on_channel = TRUE from the
678 silc_client_save_channel_key to the JOIN command reply. The
679 key payload is not received if the private channel key is set.
680 Affected file lib/silcclient/command_reply.c and the
681 lib/silcclient/client_channel.c.
683 * When the CMODE_CHANGE notify is sent and the channel private
684 key mode is removed the channel key must be re-generated in
685 other cells as well. Added this support for the router in the
686 silcd/packet_receive.c.
688 * Added new local command NOTICE to send notice message on
689 channel. Affected file silc/local_command.[ch].
691 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
693 * Added new local command ME to the client. It is used to send
694 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
695 some action. Affected file silc/local_command.[ch].
697 * Changed channel_message and private_message client operations
698 to deliver the message flags to the application. Added also
699 the `flags' arguments to the silc_client_send_channel_message
700 and silc_client_send_private_message functions. Affected file
703 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
705 * Redefined the Private Message Payload to support private message
706 keys and to support the new private message flags. Updated
707 the protocol specs. Flags makes it possible to have for example
710 * Added new type SilcPrivateMessagePayload and defined an API
711 for it in the lib/silcclient/silcprivate.[ch].
713 * Tested private message private keys successfully. Tested the
714 private message key set, unset and list commands with the new
717 * Redefined the Channel Message Payload to include the channel
718 message flags (equal with private message flags) to support
719 for example CTCP style messages.
721 * Defined some of the message (for channel and private message)
722 flags. Updated the protocol specs and added the flags to the
723 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
725 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
727 * Added SilcKeyAgreementStatus type to the key agreement routines
728 to indicate the current status and error if one occured.
729 The status types are defined in the lib/silcclient/silcapi.h.
731 * Added new local command KEY that is used to set and unset private
732 keys for channels, set and unset private keys for private messages
733 with remote clients and to send key agreement requests and
734 negotiate the key agreement protocol with remote client. The
735 key agreement is supported only to negotiate private message keys,
736 it currently cannot be used to negotiate private keys for channels,
737 as it is not convenient for that purpose.
739 * Fixed a minor pending callback setting bug in the function
740 silc_client_get_client_by_id_resolve, now the function works.
741 Affected file lib/silcclient/idlist.c.
743 * Added function silc_net_get_local_port to get local bound
744 port by socket. Added to lib/silcutil/silcnet.[ch].
746 * Added `sockets' and `sockets_count' fields to the SilcClient
747 object. They hold the sockets of the listenning sockets in
748 the client. Listenning sockets may be for example the key
749 agreement server. Affected file lib/silcclient/client.[ch].
750 Added functions the silc_client_add_socket and the
751 silc_client_del_socket. They are exported to the application
754 * Added ~./silc/clientkeys to support other client's public keys.
756 * Renamed verify_server_key client operation to verify_public_key
757 and added one argument to indicate the type of the connection
758 (server, client etc.).
760 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
762 * Added silc_server_connection_auth_request to handle the
763 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
764 silcd/packet_receive.[ch].
766 * Added silc_server_send_connection_auth_request into the
767 silcd/packet_send.c to send the connection auth request packet.
769 * Cleaned up the silcd/protocol.c a bit and fixed some memory
772 * Fixed the public key authentication in responder side in the
773 server. The `auth_data' pointer includes the SilcPublicKey
774 not the path to the public key. Affected file silcd/protocol.c.
776 * Implemented the public key authentication in the initiator side
777 in the server. Affected file silcd/protocol.c.
779 * Removed the [RedirectClient] config section from the server
780 configuration. Is not needed and I don't want to implement it.
782 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
784 * Cleaned up the CMODE command in the server. It now works
785 correctly and supports all the modes defined in the protocol.
786 Affected file is silcd/command.c.
788 * Added `hmac_name' field to the SilcChannelEntry in the server
789 to hold the default HMAC of the channel. It can be set when
790 creating the channel (with JOIN command). Affected files
793 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
794 type to indicate the change of the current cipher and hmac
795 on the channel. Client can safely ignore the <cipher> argument
796 (if it chooses to do so) since the CHANNEL_KEY packet will
797 force the channel key change anyway. The <hmac> argument is
798 important since the client is responsible of setting the new
799 HMAC and the hmac key into use.
801 * Fixed the CMODE command in the client library as well.
803 * Tested CMODE command in router environment successfully.
805 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
807 * Show the version of the remote client (or server) when connecting
808 to the server. It is logged to the log file. Affected file
811 * Fixed the KILLED notify handling in the client library. The
812 client must be removed from all channels when receiving the
815 Also, do not remove the client entry when giving the KILL
816 command but when the KILLED notify is received.
818 * Removed silc_idlist_find_client_by_nickname from the server.
819 Not needed anymore. Affected files silcd/idlist.[ch].
821 * Implemented the CHANNEL_CHANGE notify type handling to the
822 server. Affected file silcd/server.c.
826 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
828 * Added silc_server_send_notify_invite to send the INVITE
829 notify between routers.
831 * Implemented the INVITE command correctly to the server.
833 * Implemented the INVITE notify type handling in the server.
835 * Implemented the INVITE command to the client library and on the
838 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
840 * Added function silc_server_get_client_resolve to find the
841 client entry by ID from all ID lists and then resolve it
842 (using WHOIS) if it cannot be found. Affected file is
845 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
847 * Implemented the BAN command to the client library.
849 * The JOIN command in the server now checks the invite list
852 * Changed the silc_command_reply_payload_encode_va and the
853 silc_command_payload_encode_va to support that if argument is
854 NULL it ignores and checks the next argument. Affected file
855 lib/silccore/silccommand.c.
857 * Added silc_server_send_notify_ban to send the BAN notify
858 type between routers.
860 * Chaned the silc_notify_payload_encode to support that if
861 argument is NULL it ignores and checks the next argument.
862 Affected file lib/silccore/silcnotify.c.
864 * Tested ban lists in router environment successfully.
866 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
868 * Implemented BAN command to the server, in silcd/command.[ch].
870 * Removed the BAN and INVITE_LIST modes from the CMODE command
873 * Added function silc_string_match to regex match two strings.
874 Affected files lib/silcutil/silcutil.[ch].
876 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
878 * Redefined parts of the SilcChannelEntry in the server to support
879 the new ban and invite lists.
881 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
883 * Redefined the INVITE command. The same command can be used to
884 invite individuals to the channel but also to manage the invite
885 list of the channel (to add to and remove from the invite list).
886 Updated the protocol specs.
888 * Added new command SILC_COMMAND_BAN that can be used to manage
889 the ban list of the channel. Updated the protocol specs.
891 * Removed the channel modes: the SILC_CMODE_BAN and the
892 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
893 in the CMODE command. The equivalent features are now available
894 using INVITE and BAN commands. Updated the protocol specs.
896 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
897 in the network about change in the current ban list. The notify
898 type is not used by the client.
900 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
901 support the invite lists.
903 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
905 * Added new function silc_string_regexify that converts string
906 including wildcard characters into regex string that can
907 be used by the GNU regex library. Added into the file
908 lib/silcutil/silcutil.[ch].
910 Added silc_string_regex_combine to combine to regex strings
911 into one so that they can be used as one regex string by
912 the GNU regex library. Added into the file
913 lib/silcutil/silcutil.[ch].
915 Added silc_string_regex_match to match two strings. It returns
916 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
918 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
920 * Imported GNU regex to the soruce tree into lib/contrib.
921 Fixed some compiler warning from the regex.c.
923 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
925 * Fixed MOTD command in the server to work in router environment.
927 * Fixed the MOTD command in the client library to support
928 the server argument in the command.
930 * Added `nickname_len' argument to the silc_idlist_add_client
931 in the server, as the `nickname' argument may be binary data
934 * Added silc_idlist_get_channels to return all channels from
937 * Implemented LIST command to the server. Affected file is
940 * Implemented the LIST command to the client library and on the
943 * Added [<user count>] argument to the LIST command reply.
944 With private channels the user count is not shown.
946 * Updated TODO and README.
948 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
950 * The client entry's data.registered must be TRUE even with
951 global client entry on global client list. The data.registered
952 is used to check whether the client is anymore in the network,
953 for example with WHOWAS command so it must be valid.
955 * Fixed the WHOWAS command in the server. It now actually works
956 in router environment. Added function into silcd/command_reply.c
957 silc_server_command_reply_whowas_save.
959 * Added silc_idlist_purge function to the silcd/idlist.c
960 to periodically purge the ID Cache.
962 * Fixed INFO command in the server. It works now in router
963 environment. Added <server name> argument to the INFO command
964 reply. Updated the protocol specs.
966 * Fixed minor bug in silc_idcache_purge to not purge if the
967 expire value is zero.
969 * Fixed various bugs in WHOIS and IDENTIFY command handling as
970 they were buggy because of the WHOWAS information.
972 * Fixed local command MSG to handle the async resolving of
973 the remote client properly. It used to fail the first MSG.
974 Affected file silc/local_command.c.
976 * Added `data_len' field to SilcIDCache context.
978 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
980 * Update TODO. Todo in commands in the server.
982 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
984 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
985 used by routers as broadcast packet to inform other routers
986 about the changed user mode.
988 Implemented the notify handling in the server. Affected file is
989 silcd/packet_receive.c. Added the function
990 silc_server_send_notify_umode to the silcd/packet_send.[ch].
992 * Added new generic Channel Payload and deprecated the New Channel
993 Payload. The New Channel Payload is now the generic Channel
996 * Added new argument `mode' to the silc_server_send_new_channel
997 as it is required in the Channel Payload now.
999 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1000 and created a new and real SilChannelPayload to represent the
1001 new generic Channel Payload. Implemented the encode/decode
1002 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1004 * Added silc_server_get_client_channel_list to return the list
1005 of channels the client has joined for WHOIS command reply.
1006 Affected file silcd/server.[ch].
1008 * Implemented the channel list sending in the WHOIS command reply
1009 in server and in the client.
1011 Implemented the channel list displaying on the user interface
1012 as well. Affected file silc/client_ops.c.
1014 * Added silc_channel_payload_parse_list to parse list of Channel
1015 Payloads. It returns SilcDList list of SilcChannelPayloads.
1016 Client for example can use this function to parse the list of
1017 channels it receives in the WHOIS command reply. The caller
1018 must free the list by calling silc_channel_payload_list_free.
1019 Affected files lib/silccore/silcchannel.[ch].
1021 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * Added one new argument <user mode> to the WHOIS command reply
1024 to return the mode of the user in SILC. Updated the protocol
1027 Implemented it to the server and client.
1029 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * Fixed the mode printing on the user interface on joining.
1032 Affected file silc/client_ops.c.
1034 * Implemented the UMODE command and user modes in general to the
1035 client library and to the user interface.
1037 * Implemented the UMODE command to the server.
1039 * The server now sends UNKNOWN_COMMAND error status if client sends
1040 unknown command. Affected file silcd/command.c.
1042 * All server commands now handle the command identifier the right
1043 way when sending the command reply to the client. The client can
1044 use to identify the command replies with the identifier.
1046 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1048 * Added silc_server_get_client_route to resolve the route to
1049 the client indicated by the client ID. Affected file is
1052 * Added silc_server_relay_packet as general function to relay
1053 packet to arbitrary destination. This deprecates functions
1054 like _send_private_message_key, _relay_notify etc. Affected
1055 file is silcd/packet_send.[ch].
1057 Removed silc_server_send_key_agreement,
1058 silc_server_send_private_message_key and
1059 silc_server_packet_relay_notify functions from the file
1060 silcd/packet_send.[ch].
1064 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1065 server. Affected file silcd/packet_receive.[ch].
1067 * Implemented the KILL command to the client. Implemented the
1068 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1069 Affected files lib/silcclient/command[_reply].c and
1070 lib/silcclient/client_notify.c. Implemented the KILL notify
1071 printing in the user inteface.
1073 * Fixed a lot silc_parse_nick memory leaks from the client
1074 library in the file lib/silcclient/command.c.
1076 * Changed the silc_server_send_notify_on_channels's `sender'
1077 argument from SilcSocketConnection to SilcClientEntry to
1078 check the sender as entry and not as connection object and not
1079 to send to the client provided as argument. The affected file
1080 is silcd/packet_send.[ch].
1082 * The notify packets that are destined directly to the client used
1083 to not to be processed by the server. Now changed that and the
1084 server processes all notify packets. After relaying the packet
1085 to the client the notify packet is processed in the server.
1087 * The silc_server_free_client_data now checks whether there is
1088 pending outgoing traffic for the client and purges the data to
1089 the network before removing the client entry.
1091 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1093 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1094 an client is killed from the SILC Network. Updated the protocol
1097 Added new function silc_server_send_notify_killed to the
1098 silcd/packet_send.[ch].
1100 * Added function silc_server_packet_relay_notify to relay notify
1101 packets that are destined directly to a client. In this case
1102 the server does not process the notify packets but merely relays
1103 it to the client. Affected file silcd/packet_send.[ch].
1105 Added also silc_server_packet_process_relay_notify to check
1106 whereto relay the notify. Affected file is
1107 silcd/packet_receive.[ch].
1109 * Implemented the KILL command to the server.
1113 * Added the backup schema desgined last fall to the protocol
1114 specs for everyone to see. The specification is in the
1115 *-spec-xx.txt draft and the packet type definitions for the
1116 backup routers is in *-pp-xx.txt draft. Thusly, added also
1117 new packet type SILC_PACKET_CELL_ROUTERS.
1119 * A big security problem in the implementation discovered. The
1120 signoff of an client did not cause new channel key generation
1121 which it of course should've done. The channel keys must be
1122 always re-generated when client leaves (or signoffs) the channel.
1123 The silc_server_remove_from_channels funtion now handles
1124 the channel key re-generation.
1126 * Added `sender' argument to the silc_server_send_notify_on_channels
1127 to not to send the client provided as argument. Affected file
1128 silcd/packet_send.[ch].
1130 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1132 * Implemented OPER and SILCOPER commands into the server and
1135 * Added silc_auth_verify and silc_auth_verify_data to verify
1136 the authentication directly from the authentication payload.
1137 It supports verifying both passphrase and public key based
1138 authentication. Affected file lib/silccore/silcauth.[ch].
1140 * Added `hash' field to the SilcIDListData structure. It is the
1141 hash negotiated in the SKE protocol. Affected file is
1144 * Slight redesigning of the SilcAuthPayload handling routines.
1145 Do not send SilcPKCS but SilcPublicKey as argument.
1147 * Implemented the public key authentication support to the
1148 serverconfig. The public key is loaded from the provided path
1149 and saved as authentication data to void * pointer. Thus,
1150 changed the unsigned char *auth_data to void *auth_data;
1152 * Fixed SHUTDOWN command to send the reply before the server
1153 is shutdown. :) Affected file silcd/command.c.
1155 * Fixed fatal bug in CONNECT command. The hostname was invalid
1156 memory and server crashed. Affected file silcd/command.c.
1158 * Fixed fatal bug in CLOSE command. The server_entry became
1159 invalid but was referenced later in the command. Affected file
1162 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * Fixed fatal bug in failure packet handling. Server ignored
1165 the failure and thus crashed when it came.
1169 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1171 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1172 that the command may be executed only once in (about) 2 seconds.
1173 The old SILC_CF_LAG flag is same but allows command bursts up
1174 to five before limiting.
1176 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1177 server code. Various commands now includes the CF_LAG_STRICT
1178 flag to disallow any kind of miss-use of the command.
1180 * Fixed the silc_buffer_unformat to not to allocate any data
1181 if the length of the data is zero. It used to allocate the
1182 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1184 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1186 * Changed the format of AdminConnection configuration section
1187 in the server. Added username of the admin to the format.
1188 Affected files silcd/serverconfig.[ch].
1190 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1191 to return admin configuration data by host, username and/or
1194 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * Implemented WHOWAS command to the server. Added the functions:
1198 silc_server_command_whowas_parse,
1199 silc_server_command_whowas_send_reply,
1200 silc_server_command_whowas_from_client and
1201 silc_server_command_whowas_from_server
1203 * Added <Client ID> argument to the WHOWAS command reply. Updated
1204 the protocol specs accordingly.
1206 * Implemented WHOWAS command and command_reply to the client
1209 Implemented the WHOWAS printing on the user interface.
1211 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Added new argument to the WHOWAS command reply, the real name.
1214 It is an optional argument. Updated the protocol specs.
1216 * Added SilcIDCacheDestructor callback that is registered when
1217 the SilcIDCache is allocated. The callback is called when
1218 an cache entry in the ID Cache expires, or is purged from the
1219 cache. Added into lib/silccore/idcache.[ch].
1221 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1222 to destruct the client entries when the cache entry expires.
1223 Other ID Cache's in server and in the client library ignores
1226 * If the ID Cache entry's `expire' field is zero then the entry
1227 never expires. Added boolean `expire' argument to the
1228 silc_idcache_add function in the lib/silccore/idcache.[ch].
1229 If it is TRUE the default expiry value is used.
1231 * Added silc_server_free_client_data_timeout that is registered
1232 when client disconnects. By default for 5 minutes we preserve
1233 the client entry for history - for WHOWAS command.
1235 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1237 * Added support to the server to enforce that commands are not
1238 executed more than once in 2 seconds. If server receives
1239 commands from client more frequently, timeout is registered
1240 to process the commands. Affected file silcd/command.c.
1241 Added new function silc_server_command_process_timeout.
1243 * Changed NICK_NOTIFY handling in client library to check that
1244 if the client's nickname was changed, so there is no need to
1245 resolve anything from the server.
1247 * Removed error printing from the WHOIS and IDENTIFY commands.
1248 If error occurs then it is ignored silently in the client library.
1249 The application, however, may map the received error to
1250 human readable error string. The application currently maps
1251 the NO_SUCH_NICKNAME error to string.
1253 * Made the command status message public to the application. Moved
1254 them from lib/silcclient/command_reply.c to
1255 lib/silcclient/command_reply.h. The application can map the
1256 received command status to the string with the
1257 silc_client_command_status_message function.
1259 * Added check to the server to check that client's ID is same
1260 as the Source ID in the packet the client sent. They must
1263 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1265 * Added dist-bzip hook to the Makefile.am to make bzip2
1266 compressed distributions.
1268 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1270 * Server now enforces the maximum length for the nickname and
1271 the channel as protocol specification dictates. 128 bytes for
1272 nickname and 256 bytes for channel name.
1274 * Moved the WHOIS printing to the application. The client libary
1275 does not print out the WHOIS information anymore, the application
1276 must do it. Renamed silc_client_command_reply_whois_print to
1277 the silc_client_command_reply_whois_save.
1279 The client's idle time is also sent to the application now, and
1280 the idle is shown on screen.
1282 * Added silc_client_command_reply_identify_save to save the
1283 received IDENTIFY entries.
1285 * Do not check for channel private keys in message sending and
1286 reception if the channel does not have the PRIVKEY mode set.
1287 Affected file lib/silclient/client_channel.c.
1289 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1291 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1292 just surfaced after chaning the JOIN procedure.
1294 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1296 * Added silc_client_get_clients_by_list to get client entries
1297 from Client ID list, that is returned for example by JOIN
1298 and USERS command replies. The application should use this
1299 function for example when JOIN command reply is received to
1300 resolve the clients already on the channel (library does not
1301 do that anymore as USERS command reply is not used in the JOIN
1302 procedure anymore). Affected files lib/silcclient/silcapi.h and
1303 lib/silcclient/idlist.c.
1305 * JOIN command reply and USERS command reply returns now SilcBuffer
1306 pointers instead of unsigned char pointers when returning
1307 the client list and mode list.
1309 * Added <Client ID> argument to the JOIN command reply, mainly
1310 for the server to identify for which client the command was
1311 originally sent. Updated protocol specs accordingly.
1313 * Added SilcDlist private_key pointer to the SilcChannelEntry
1314 in the client to support the channel private keys. Affected
1315 file is lib/silcclient/idlist.h.
1317 * Added SilcChannelPrivateKey argument to the function
1318 silc_client_send_channel_message so that application can choose
1319 to use specific private ke if it wants to. If it is not provided,
1320 the normal channel key is used, unless private keys are set.
1321 In this case the first (key that was added first) is used
1322 as the encryption key.
1324 * Implemented the support for channel private key handling.
1325 Implemented the following functions:
1327 silc_client_add_channel_private_key,
1328 silc_client_del_channel_private_keys,
1329 silc_client_del_channel_private_key,
1330 silc_client_list_channel_private_keys and
1331 silc_client_free_channel_private_keys
1333 Affected file lib/silcclient/client_channel.c.
1335 * Added the support for the private keys in the channel message
1336 sending and encryption and in the message reception and
1337 decryption. Affected funtions are
1338 silc_client_send_channel_message and silc_client_channel_message.
1340 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1342 * Added SKE's key verify callback to the client library's
1343 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1345 * Removed the statement that server (or router) must send USERS
1346 command reply when joining to the channel so that the client
1347 knows who are on the channel. Instead, the client list and
1348 client's mode list is now sent in the JOIN command reply to the
1349 client who joined channel. This is better solution.
1351 * Added function silc_server_get_users_on_channel and function
1352 silc_server_save_users_on_channel to the silcd/server.[ch].
1354 * Removed function silc_server_command_send_users from the
1357 * Do not show topic on the client library anymore. The topic is
1358 sent in the command reply notify to the application and the
1359 application must show the topic now.
1361 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Added client searching by nickname hash into the IDENTIFY and
1364 WHOIS commands in the server as they were clearly missing from
1365 them. Affected file is silcd/command.c.
1367 * Fixed a bug in private message receiving in the client library.
1368 The remote ID was freed and it wasn't supposed, now it is
1371 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1373 * Minor fix to the channel payload; allocate the data area, as it
1374 needs to be of specific length.
1376 * If the key agreement port is zero then the operating
1377 system will define the bound port. Affected files are
1378 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1380 * Added new function silc_channel_payload_decrypt into the file
1381 lib/silccore/silcchannel.[ch].
1383 * Moved the channel message etc, check from silc_packet_decrypt
1384 to applications. The library calls now a generic
1385 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1386 when the packet is either normal or special. This was done to
1387 allow more wide range of checking that was not allowed when
1388 the code was in library. Now applications can do virtually any
1389 checks to the packet and return to the library the decision how
1390 the packet should be processed. Affected files are
1391 lib/silccore/silcpacket.[ch].
1393 Added silc_server_packet_decrypt_check to the server and
1394 silc_client_packet_decrypt_check to the client library.
1396 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1397 to send with specified source and destination information.
1399 * Channel message delivery between routers was broken after the
1400 channel key distribution was fixed earlier. The channel key
1401 was used be to distributed to other routers as well which is not
1402 allowed by the protocol. Now this is fixed and channel keys
1403 really are cell specific and the channel message delivery between
1404 routers comply with the protocol specification.
1406 * Fixed various commands in server to check also the global list
1407 for the channel entry and not just the local list. The affected
1408 file silcd/command.c.
1410 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Added assert()s to buffer formatting and unformatting routines
1413 to assert (if --enable-debug) when error occurs. Affected
1414 file: lib/silcutil/silcbuffmt.c.
1416 * Changed to auto-reconnect to check whether the remote host is
1417 router and register the re-connect timeout if it is. It used
1418 to check that whether we are normal server, but router must do
1419 auto-reconnect with another router as well. Affected file
1422 * Removed the [<key len>] option from CMODE command as the cipher
1423 name decides the key length, nowadays. See the defined ciphers
1424 from the protocol specification.
1426 * Added [<hmac>] option to the CMODE command to define the HMAC
1427 for the channel. Added SILC_CMODE_HMAC channel mode.
1429 * Added [<hmac>] option for the JOIN command so that user can
1430 select which HMAC is used to compute the MACs of the channel
1433 * Added Hmac field to the Channel Message Payload. The integrity
1434 of plaintext channel messages are now protected by computing
1435 MAC of the message and attaching the MAC to the payload. The
1436 MAC is encrypted. Now, it is clear that this causes some
1437 overhead to the size of the packet but rationale for this is that
1438 now the receiver can verify whether the channel message decrypted
1439 correctly and also when private keys are set for the channel the
1440 receiver can decrypt the packet with several keys and check from
1441 the MAC which key decrypted the message correctly.
1443 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1444 lib/silccrypt/silccipher.[ch].
1446 * Added silc_hash_len to return the digest length into the
1447 lib/silcrypt/silchash.[ch].
1449 * Rewrote parts of Silc Channel Payload interface in the
1450 lib/silccore/silcchannel.[ch]. The encode function now also
1451 encrypts the packet and parse function decrypts it.
1453 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Fixed a minor formatting bug in the SKE's key material processing.
1456 It actually might have processed the keys wrong way resulting
1459 * Redefined the mandatory HMAC algorithms and added new algorithms.
1460 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1461 and hmac-md5 truncated to 96 bits. The mandatory is now
1462 hmac-sha1-96. Rest are optional (including the one that used
1463 to be mandatory). Rationale for this is that the truncated HMAC
1464 length is sufficient from security point of view and can actually
1465 make the attack against the HMAC harder. Also, the truncated
1466 HMAC causes less overhead to the packets. See the RFC2104 for
1469 * Added new [hmac] configuration section. The SKE used to use
1470 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1471 is of course wrong. The official names that must be proposed in
1472 the SKE are the ones defined in the protocol specification
1473 (hmac-sha1-96 for example). The user can configure any hmac
1474 using any hash function configured in the [hash] section. At
1475 least, the mandatory must be configured.
1477 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1479 * Added HMAC list to the SKE proposal list. It has now both
1480 hash algorithm list and HMAC list. This makes the protocol
1481 incompatible with previous versions. The SKE now seems to work
1482 the way it is supposed to work, for the first time actually.
1484 * Defined plain Hash algorithms to the protocol specification.
1487 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1489 * Implemented support for key agreement packets into the server.
1490 Added functions silc_server_key_agreement and
1491 silc_server_send_key_agreement. Other than these functions,
1492 server has nothing to do with this packet.
1494 * Added support for private message key packets into the server.
1495 Added functions silc_server_private_message_key and
1496 silc_server_send_private_message_key.
1500 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1501 called in the protocol's final callback instead in the END
1502 protocol state. This makes a little more sense and in the same
1503 time in client we can use the same protocol routines for normal
1504 key exchange and to key agreement packet handling as well.
1506 * Added to both client's and server's KE protocol context the
1507 SilcSKEKeyMaterial pointer to save the key material. We will
1508 bring the key material to the protocol's final callback by doing
1509 this. The final callback must free the key material.
1511 * Added SKE's packet_send callback into client's KE protocol
1512 context so that the caller can choose what packet sending function
1513 is used. This way we can use different packet sending when
1514 doing normal SKE when doing key agreement packet handling (in
1515 the key agreement packet handling we do not want to encrypt
1518 * Implemented the responder side of the key agreement routines
1519 in the client. The client can now bind to specified port and
1520 accept incoming key negotiation. The key material is passed
1521 to the application after the protocol is over.
1523 * Implemented the processing of incoming Key Agreement packet
1524 in the client. Added function silc_client_key_agreement to
1527 * Implemented the intiator side of the key agreement routines
1528 in the client. The client can now initiate key agreement with
1529 another remote client. The key material is passed to the
1530 application after the protocol is over.
1532 * Created client_keyagr.c to include all the key agreement
1535 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1536 SILC_TASK_CALLBACK except that it is not static.
1538 * Created client_notify.c and moved the Notify packet handling
1539 from the client.[ch] into that file.
1541 * Created client_prvmsg.c and moved all private message and
1542 private message key routines from the client.[ch] into that file.
1544 * Create client_channel.c and moved all channel message and
1545 channel private key routines from the client.[ch] into that file.
1547 * Changed silc_client_get_client_by_id_resolve to resolve with
1548 WHOIS command instead of IDENTIFY command, in the file
1549 lib/silclient/idlist.c.
1551 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1553 * Implemented the SKE's responder side to the Client library.
1555 * When FAILURE is received to the protocol do not trust it
1556 blindly. Register a timeout to wait whether the remote closes
1557 the connection as it should do it, only after that process the
1558 actual failure. This was changed to both client and server.
1560 * Added client_internal.h to include some of the structures
1561 there instead of client.h in lib/silcclient/.
1563 * Added function silc_task_unregister_by_callback to unregister
1564 timeouts by the callback function.
1566 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * Some "Incomplete WHOIS info" errors has been appearing on the
1569 log files. Took away the entry->userinfo check from WHOIS
1570 reply sending. The entry->userinfo is now " " if client did not
1571 provide one. I thought this was fixed earlier but something
1572 is wrong still. Let's see if the error still appears.
1574 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Fixed a minor bug in the login when the channel key is
1577 re-generated in the server. It used to generate the key in
1578 wrong order and thus caused problems in the channel traffic.
1580 * Fixed a minor bug in channel key distsribution after
1581 KICK command. The key was not sent to the router even though
1584 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Added silc_ske_process_key_material_data as generic routine
1587 to process any key material as the SILC protocol dictates. The
1588 function is used by the actual SKE library but can be used by
1589 applications as well. This relates to the private message keys
1590 and the channel private keys since they must be processed the
1591 same way the normal SILC session keys. The protocol dictates
1592 this. Affected files: lib/silcske/silcske.[ch].
1594 Added also silc_ske_free_key_material to free the
1595 SilcSKEKeyMaterial structure.
1597 * Defined silc_cipher_set_key function to set the key for
1598 cipher without using the object's method function. The affected
1599 files: lib/silccrypt/silccipher.[ch].
1601 * Implemented silc silc_client_add_private_message_key,
1602 silc_client_add_private_message_key_ske,
1603 silc_client_del_private_message_key,
1604 silc_client_list_private_message_keys and
1605 silc_client_free_private_message_keys functions in the
1608 Added functions silc_client_send_private_message_key to send
1609 the Private Message Key payload and silc_client_private_message_key
1610 to handle incoming Private Message Key payload.
1612 * Added Cipher field to the Private Message Key payload to set
1613 the cipher to be used. If ignored, the default cipher defined
1614 in the SILC protocol (aes-256-cbc) is used.
1616 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1618 * Removed lib/silcclient/ops.h file.
1620 Redefined parts of the SILC Client Library API. Created new
1621 file silcapi.h that deprecates the ops.h file and defines the
1622 published Client Library API. Defined also private message key
1623 API and channel private key API into the file.
1625 This is the file that the application must include from the
1626 SILC Client Library. Other files need not be included by
1627 the application anymore.
1629 * Added new key_agreement client operation callback and also
1630 defined the Key Agreement library API for the application.
1632 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1634 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1635 is used by clients to request key negotiation between another
1636 client in the SILC network. If the negotiation is started it
1637 is performed using the SKE protocol. The result of the
1638 negotiation, the secret key material, can be used for example
1639 as private message key.
1641 Implemented the Key Agreement payload into the files
1642 lib/silccore/silauth.[ch].
1644 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1646 * Redefined ciphers for the SILC protocol. Added some new ciphers
1647 and defined the key lengths for the algorithms. Changed the
1648 code accordingly. The default key length is now 256 bits.
1650 * Fixed SKE key distribution function silc_ske_process_key_material
1651 when the key length is more than 128 bits. The default key
1652 length in SILC is now 256 bits.
1654 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1655 to indicate unsupported algorithm.
1657 * Renamed rijndael.c to aes.c and all functions as well.
1659 * Fixed a long standing channel key setting bug in client library.
1660 Weird that it has never surfaced before.
1662 * Fixed bug in channel deletion. If the entire channel is removed
1663 then it must also delete the references of the channel entry
1664 from the client's channel list as the client's channel entry and
1665 the channel's client entry share same memory.
1667 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1669 * Implemented CONNECT and SHUTDOWN commands in the client.
1671 * Implemented CLOSE command to the client.
1673 * Added the function silc_idlist_find_server_by_name into the
1674 files silcd/idlist.[ch].
1676 Added the function silc_idlist_find_server_by_conn into the
1677 files silcd/idlist.[ch].
1679 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1681 * DIE command was renamed to SHUTDOWN. Updated the both code
1684 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1685 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1687 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1690 * Added function silc_server_create_connection function to create
1691 connection to remote router. My server implementation actually
1692 does not allow router to connect to normal server (it expects
1693 that normal server always initiates the connection to the router)
1694 so the CONNECT command is only good for connecting to another
1697 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1699 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1700 or some other client was kicked from the channel.
1702 Implemented the handling of the notify type to both client
1705 Implemented silc_server_send_notify_kicked to send the KICKED
1706 notify. It is used to send it to the server's primary router.
1708 * Implemented the KICK command into server and client.
1710 * Added `query' argument to the silc_idlist_get_client function
1711 to indicate whether to query the client from server or not if
1714 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1715 to indicate that the client is not channel founder.
1719 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1721 * Removed the rng context from SilcPacketContext structure and
1722 changed that the packet routine uses the Global RNG API.
1724 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Added support for quit message that client can "leave" on the
1727 channel when it quits the SILC. It is ditributed inside the
1728 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1730 Added silc_server_free_client_data that will take the
1731 signoff message as argument.
1733 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1735 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1737 * Updated parts of the protocol specification to keep it up
1740 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1742 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1743 payloads in one packet.
1745 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1746 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1747 use now the new List flag.
1749 * Also deprecated the following packet types: REPLACE_ID,
1750 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1752 * Added list support for Notify packet in server.
1754 * Added silc_server_send_notify_channel_change to send the
1755 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1756 the silc_server_send_replace_id.
1758 * Added silc_server_send_notify_nick_change to send the
1759 NICK_CHANGE notify type. Deprecates the function
1760 silc_server_send_replace_id.
1762 * Added silc_server_send_notify_join to send the JOIN notify type.
1763 Deprecates the function silc_server_send_new_channel_user.
1765 * Added silc_server_send_notify_leave to send LEAVE notify type.
1766 Deprecates the function silc_server_send_remove_channel_user.
1768 * Added silc_server_send_notify_cmode and
1769 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1770 types. Deprecates the silc_server_send_set_mode function.
1772 * Added SERVER_SIGNOFF notify type to indicate that server has
1773 quit. This means that all clients on the channel from that
1774 server will drop. This can be also used when netsplit happens.
1776 Deprecated REMOVE_ID packet type since it is not needed anymore
1779 Added silc_server_send_notify_server_signoff to send the
1780 SERVER_SIGNOFF notify type. Deprecates the function
1781 silc_server_send_remove_id.
1783 Added also silc_server_send_notify_signoff to send the
1784 SIGNOFF notify type.
1786 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1787 SILC protocol from this day on. Changed the protocol
1788 specification as well.
1790 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1791 notify type. It is used between routers to notify about
1792 topic changes on a channel.
1794 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1797 * Partly updated the protocol specification to comply with the
1798 changes now made. It is still though a bit outdated.
1800 * The JOIN notify type now takes one extra argument <Channel ID>.
1801 The packet used to be destined to the channel but now the
1802 JOIN type may be sent as list thus it is impossible to
1803 destine it to any specific channel. By adding this argument
1804 it is again possible.
1806 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1808 * Added CREDITS file. The CHANGES and CREDITS file will appear
1809 in the distribution as well.
1811 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1813 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1814 types in the server's silcd/packet_receive.c.
1816 * Implemented CMODE and CUMODE to work in router environment.
1818 * Fixed minor encoding and decoding buglet from the
1819 lib/silccore/silcmode.c.
1821 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1824 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1826 * Changed all SilcConfigServer* and silc_config_server* to
1827 SilcServerConfig* and silc_server_config*, respectively.
1830 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1832 * Associated the ID (client or server ID) to the Authentication
1833 Payload to avoid any possibility of forging. Updated the
1834 protocol specification and the code accordingly.
1836 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1838 * The RSA key length is now save to the RsaKey context in the
1839 key generation process in lib/silccrypt/rsa.c. The key length
1840 is now used to figure out the maximum size of the block allowed
1841 to be encrypted/signed.
1843 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1844 is equivalent to the silc_mp_mp2bin but does not allocate any
1847 * Changed silc_mp_mp2bin API to take length argument. If it is
1848 non-zero then the buffer is allocated that large. If zero, then
1849 the size is approximated using silc_mp_sizeinbase, which however
1852 * Created Global RNG API which is global RNG that application can
1853 initialize. After initializing, any routine anywhere in the
1854 code (including library) can use RNG without allocating a new
1855 RNG object. This was done to allow this sort of use of the
1856 RNG in code that has no chance to allocate RNG object. All
1857 applications currently allocate this and many routines in the
1858 library use this. Affected file lib/silccrypt/silcrng.[ch].
1860 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1861 it to use the Global RNG API.
1863 * Defined Authentication Payload into protocol specification that
1864 is used during SILC session to authenticate entities. It is
1865 used for example by client to authenticate itself to the server
1866 to obtain server operator privileges.
1868 Implemented this payload into the lib/silccore/silcauth.[ch].
1869 Implemented also routines for public key based authentication
1870 as the new protocol specification dictates.
1872 Moved definitions of different authentication methods from
1873 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1875 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1876 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1877 silc_pkcs_verify_with_hash functions into the file
1878 lib/silccrypt/silcpkcs.[ch].
1880 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1882 * The client entry's userinfo pointer must be always valid.
1883 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1884 will fail since it requires the userinfo. Now, the userinfo
1885 is allocated as "" if actual userinfo does not exist. Actually,
1886 it must exist and it is totally Ok to drop client connections
1887 that does not announce the userinfo. However, we will make
1888 this workaround for now.
1890 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1891 to return the remote port by socket.
1893 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1895 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1896 SILC_SERVER_PENDING_EXEC and added an new macro
1897 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1898 data or when error occurs while processing the pending command.
1900 Added new argument `destructor' into silc_server_command_pending
1901 and to the SilcServerCommandPending object. This destructor is
1902 now called after calling the pending callback or if error occurs
1903 immediately. If error occurs the actual pending callback won't
1904 be called at all - only the destructor. The destructor may be
1905 NULL if destructor is not needed.
1907 All this applies for client library code as well. Similar
1908 changes were made there as well for the pending commands.
1910 In the client, the application must now allocate the
1911 SilcClientCommandContext with the silc_client_command_alloc
1914 * Added reference counter to the SilcServerCommandContext. Added
1915 function silc_server_command_alloc and silc_server_command_dup
1918 Same type of functions added to the client library for the same
1921 * Removed the cmd_ident from IDListData away since it is now
1922 global for all connections. It is the command identifier used
1923 in command sending and with pending commands. The affected file
1926 * Added reference counter to the SilcSocketConnection objecet to
1927 indicate the usage count of the object. The object won't be
1928 freed untill the reference counter hits zero. Currently only
1929 server uses this, and client ignores it. The client must be
1930 set to use this too later. The affected files are
1931 lib/silccore/silcsockconn.[ch]. Added also the function
1932 silc_socket_dup to increase the reference counter.
1934 This was mainly added because it is possible that the socket
1935 is removed underneath of pending command or other async
1936 operation. Now it won't be free'd and proper DISCONNECTING
1937 flags, etc. can be set to avoid sending data to connection that
1938 is not valid anymore.
1940 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1941 the connection. After that it sets SILC_SET_DISCONNECTED.
1942 It is, however, possible that the socket data is not still freed.
1943 The silc_server_packet_process now checks that data is not
1944 read or written to connection that is DISCONNECTED. The socket
1945 get's freed when the reference counter hits zero.
1947 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1949 * Changed the client operation API: channel_message operation's
1950 `sender' is now the client entry of the sender, not the nickname
1951 and the `channel' is the channel entry, not the channel name.
1953 In the private_message operation the `sender' is now also the
1954 client entry of the sender not the nickname.
1956 Affected file is lib/silcclient/ops.h and all applications
1957 using the client operations.
1959 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1961 * Moved the calling of ops->connect() from connect_to_server_final
1962 into receive_new_id functin since that is the point when the
1963 client is actually allowed to send traffic to network. The
1964 affected file is lib/silcclient/client.c.
1966 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1968 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1969 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1970 (if needs broadcasting) instead of broadcasting the packets one
1971 by one which would make a burst in the network traffic.
1973 * Added `broadcast' argument to the functions in silcd/server.[ch]
1974 silc_server_create_new_channel[_with_id] to indicate whether
1975 to send New Channel packet to primary router.
1977 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1979 * Added new function into the silcd/server.[ch] files:
1980 silc_server_create_new_channel_with_id to create new channel with
1981 already existing Channel ID.
1983 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1984 lib/silccore/silcpacket.h. This packet is used t send list of
1985 Set Mode payloads inside one packet. Server uses this to set
1986 the modes for the channels and clients on those channels, that it
1987 announced to the router when it connected to it. The protocol
1988 specification has been updated accordingly.
1990 * The silc_server_new_channel did not handle the packet coming
1991 from normal server as it normally does not send that. However,
1992 when it announces its channels it does send it. Implemented
1993 the support for that.
1995 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1996 into the file lib/silccore/id.h.
1998 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2000 * Fixed memory leaks in the functions silc_idlist_del_client,
2001 silc_idlist_del_channel and silc_idlist_del_server in the file
2002 silcd/idlist.c. All of those leaked like a sieve.
2004 * Fixed some small memory leaks in the client's function
2005 silc_client_notify_by_server.
2007 * Added functions into silcd/server.c: silc_server_announce_clients,
2008 silc_server_announce_channels and silc_server_announce_server.
2009 These functions are used by normal and router server to announce
2010 to its primary router about clients, channels and servers (when
2011 router) that we own. This is done after we've connected to the
2014 These functions effectively implements the following packet types:
2015 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2016 and SILC_PACKET_NEW_ID_LIST.
2018 * Added new functions into the silcd/packet_receive.[ch]:
2019 silc_server_new_id_list, silc_server_new_channel_list and
2020 silc_server_new_channel_user_list to handle the incoming
2021 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2023 * Added support of changing Channel ID in the function
2024 silc_server_replace_id. If the server that announces a channel
2025 to the router already exists in the router (with same name but
2026 with different Channel ID), router is responsible to send
2027 Replace ID packet to the server and force the server to change
2028 the Channel ID to the one router has.
2030 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2031 client that the Channel ID has been changed by the router. The
2032 normal server sends this to the client. Client must start using
2033 the new Channel ID as the channel's ID.
2035 Implemented handling of this new type into lib/silcclient/client.c
2036 into the function silc_client_notify_by_server.
2038 * Added new function silc_idlist_replace_channel_id into the files
2039 silcd/idlist.[ch] to replace the Channel ID.
2041 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2043 * Call silc_server_command_identify_check always when processing
2044 the IDENTIFY command in silcd/command.c
2046 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2048 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2049 send keepalive packets. The packet can be sent by clients,
2050 servers and routers.
2052 Added function silc_socket_set_heartbeat into the file
2053 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2054 If not set, the heartbeat is not performed. The actual
2055 heartbeat is implemented in the low level socket connection
2056 library. However, application is responsible of actually
2059 Added silc_server_send_heartbeat to send the actual heartbeat
2060 packet into silcd/packet_send.[ch]. Server now performs
2061 keepalive with all connections.
2063 * Added silc_task_get_first function into lib/silcutil/silctask.c
2064 to return the timeout task with shortest timeout. There was a bug
2065 in task unregistration that caused problems. TODO has been
2066 updated to include that task system must be rewritten.
2068 * The client library will now resolve the client information when
2069 receiving JOIN notify from server for client that we know but
2070 have incomplete information.
2072 * Rewrote parts of silc_server_remove_from_channels and
2073 silc_server_remove_from_one_channel as they did not remove the
2074 channel in some circumstances even though they should've.
2076 * Encryption problem encountered in server:
2078 The LEAVE command used to send the Channel Key packet to the
2079 router immediately after generating it. However, the code
2080 had earlier sent Remove Channel user packet but not immediately,
2081 ie. it was put to queue. The order of packets in the router
2082 was that Channel Key packet was first and Remove Channel User
2083 packet was second, even though they were encrypted in the
2084 reverse order. For this reason, MAC check failed. Now, this
2085 is fixed by not sending the Channel Key packet immediately but
2086 putting it to queue. However, this is more fundamental problem:
2087 packets that are in queue should actually not be encrypted
2088 because packets that are sent immediately gets encrypted
2089 actually with wrong IV (and thus MAC check fails). So, packets
2090 that are in queue should be encrypted when they are sent to
2091 the wire and not when they put to the queue.
2093 However, the problem is that the current system has not been
2094 designed to work that way. Instead, the packet is encrypted
2095 as soon as possible and left to the queue. The queue is then
2096 just purged into wire. There won't be any fixes for this
2097 any time soon. So, the current semantic for packet sending
2100 o If you send packet to remote host and do not force the send
2101 (the packet will be in queue) then all subsequent packets to the
2102 same remote host must also be put to the queue. Only after the
2103 queue has been purged is it safe again to force the packet
2106 o If you send all packets immediately then it safe to send
2107 any of subsequent packets through the queue, however, after
2108 the first packet is put to queue then any subsequent packets
2109 must also be put to the queue.
2111 Follow these rules and everything works fine.
2113 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2115 * Added new function silc_server_remove_clients_by_server to
2116 remove all client entries from ID list when the server connection
2117 is lost. In this case it is also important to invalidate all
2118 client entires as they hold the invalid server entry. This
2119 fixes fatal bug when server has lost connection and will reconnect
2122 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2124 * Made some sanity checks to silc_server_daemonise like to check
2125 whether the requested user and group actually exists.
2127 * Added sanity check to SKE's silc_ske_responder_finish to check
2128 that the public and private key actually is valid.
2130 * Invalidate the client's nickname when receiving Replace ID
2131 packet and the Client ID is being replaced. This means that the
2132 server will query the nickname if someone needs it (client)
2135 * Sort the ID Cache in client library when the ID Cache data
2136 has changed (needs sorting).
2138 * Do not allow for SILC client to create several connections to
2139 several servers. The client does not support windows right now
2140 and generating multiple connections causes weird behaviour.
2142 Irssi-silc client does support windows and can handle several
2143 connections without problems, see: www.irssi.org and SILC plugin.
2145 * Fixed some places where client was added to the IDList. The
2146 rule of thumb is following (in order to get everything right):
2147 If the client is directly connected local client then the
2148 `connection' argument must be set and `router' argument must be
2149 NULL to silc_idlist_add_client function. If the client is not
2150 directly connected client then the `router' argument must
2151 bet set and the `connection' argument must be NULL to the
2152 silc_idlist_add_client function.
2154 * The funtion silc_server_packet_send_local_channel actually did
2155 not check whether the client was locally connected or not. It
2156 does that now. Fixed a bug related to LEAVE command.
2158 * Fixed Remove Channel User payload parsing bug in server's
2159 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2161 * The server's silc_server_save_channel_key now checks also the
2162 global ID list for the channel as it might not be in the local
2163 list. Fixed a bug related to LEAVE command.
2165 * Is this the end of the [<unknown>] buglet that has been lurking
2166 around for a long time? A little for loop fix in server's
2167 silc_server_command_whois_parse that is used by both IDENTIFY
2168 and WHOIS command. At least, this was a clear bug and a cause
2169 of one type of [<unknown>] buglet.
2171 * WHOIS and IDENTIFY commands call the function
2172 silc_server_command_[whois/identify]_check function even if
2173 we are not router server.
2175 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2177 * Added --with-gmp configuration option. If set the GMP
2178 is always compiled in the SILC source tree. If not set then
2179 it is checked whether the system has the GMP3 installed. If
2180 it has then the GMP won't be compiled (the system's headers
2181 and library is used), if it doesn't have it then the GMP is
2182 compiled in the SILC source tree.
2184 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2186 * Changed RSA private exponent generation to what PKCS #1
2187 suggests. We try to find the smallest possible d by doing
2188 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2189 not security fix but optimization.
2191 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2193 * Added new config entry [Identity] to fork the server and run
2194 it as specific user and group. A patch from Bostik.
2196 * Imported Dotconf configuration library into lib/dotconf.
2197 This will be used to create the SILC configuration files later.
2198 It will appear in the distsribution after this commit.
2200 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * A big code auditing weekend happening. Auditing code for
2203 obvious mistakes, bugs and errors. Also, removing any code
2206 Removed files for being obsolete:
2208 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2209 inline in the file lib/silcutil/silcbuffer.h)
2211 o lib/silcutil/silcbufutil.c (the header has inline versions)
2213 Changed code to fix possible error conditions:
2215 o The buffer formatting routines now check that the destination
2216 buffer really has enough space to add the data. This applies for
2217 both buffer formatting and unformatting
2218 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2219 unformatting was changed to accomodate following rules:
2220 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2221 sent to the function while XXX_*STRING will not allocate or copy
2222 the data into the buffer. Instead it sets the pointer from the
2223 buffer into the pointer sent as argument (XXX_*STRING used to
2224 require that the pointer must be allocated already). This change
2225 makes this whole thing a bit more consistent and more optimized
2226 (note that the data returned in the unformatting with XXX_*STRING
2227 must not be freed now). The routines return now -1 on error.
2229 o Tried to find all code that use buffer_format and buffer_unformat
2230 and added return value checking to prevent formatting and
2231 especially unformatting errors and possible subsequent fatal
2234 o Changed ske->x and ske->KEY to mallocated pointers in
2235 lib/silcske/silcske.h. Fixed possible data and memory leak.
2237 o Added return value checking to all *_parse* functions. Fixed
2238 many memory leaks as well.
2240 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2241 so that buffer overflows would not happen. All code now also
2242 checks the return value as it can fail.
2244 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2246 * Added reconnection support to server if the normal server looses
2247 its connection to the router (for example if router is rebooted).
2248 The server performs normal reconnection strategy implemented
2249 to the server. Affected file silcd/server.c.
2251 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Added new packet type SILC_PACKET_SET_MODE that is used to
2254 distribute the information about changed modes (for clients,
2255 channels and clients channel modes) to all routers in the
2256 network. Updated the protocol specification accordingly.
2258 Added functions into silcd/packet_send.c and
2259 silcd/packet_receive.c: silc_server_send_set_mode,
2260 silc_server_set_mode.
2262 Added new files silcmode.[ch] into lib/silccore that implements
2263 the encoding and decoding of Set Mode Payload. Added new type
2264 SilcSetModePayload. Moved the definitions of different modes
2265 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2267 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2269 * Oops, a little mistake in server's connection authentication
2270 protocol. The protocol is not ended with FAILURE but with
2271 SUCCESS if the authentication is Ok. :) Affected file is
2274 * Implemented NICK_CHANGE notify handling in server in the file
2275 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2276 the local clients on the channel. After the changing nickname
2277 in router environment snhould work and the [<unknown>] nickname
2278 should appear no more.
2280 The silc_server_replace_id function that receives the Replace ID
2281 payload now sends the NICK_CHANGE notify type also in the file
2282 silcd/packet_receive.c
2284 * Changed WHOIS and IDENTIFY command to support the maximum amount
2285 of arguments defined in protocol specs (3328 arguments). This
2286 fixed a bug that caused problems when there were more than three
2289 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2291 * Added extra parameter, command identifier, to the
2292 silc_client_send_command so that explicit command identifier
2295 Changed that ID list routines uses specific command identifier
2296 when sending WHOIS/IDENTIFY requests to the server so that they
2297 can be identified when the reply comes back.
2299 Affected files lib/silcclient/command.[ch],
2300 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2302 * Added `sender' argument to silc_server_packet_send_to_channel
2303 to indicaet the sender who originally sent the packet to us
2304 that we are now re-sending. Ignored if NULL. Affected file
2305 silcd/packet_send.[ch].
2307 * Added some server statistics support in silcd/server_internal.h
2308 SilcServerStatistics structure and around the server code. Also
2309 send some nice statistics information when client is connecting
2312 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2314 * Fixed channel ID decoding in server's JOIN command reply in
2315 silcd/command_reply.c
2317 * Fixed braodcasting of replace ID payload to not to send it if
2318 we are standalone server in silcd/packet_receive.c.
2320 * Fixed all channel message sending routines to not to send
2321 packets to clients that has router set, since they are routed
2322 separately in the same function earlier. Affects file
2323 silcd/packet_send.c and all channel packet sending functions.
2325 * In USERS reply, res_argv[i] are not allocated, the table
2326 is allocated. Thus changed that free the table, not its
2329 * In server's whois_check and identify_check if the client is
2330 locally connected do not send any WHOIS commands - they are not
2333 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2335 * Fixed some minor bugs in client when sending WHOIS command. The
2336 arguments was in wrong order.
2338 * Removed statis function add_to_channel from server in
2339 silcd/command.c that was previously used with the joining but
2342 * Tested USERS command in router environment successfully with two
2343 routers, two servers and two clients.
2345 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2347 * Reorganized the USERS command and command reply in client library
2348 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2349 When the command is given by user we register a pending command
2350 callback that will reprocess the command after the reply has been
2351 received from the server. When reprocessing the packet we then
2352 display the information. Thus, the USERS information is displayed
2353 now in the command callback instead of in the command reply
2354 callback. The processing of the command is same as previously
2355 when server has sent the command reply in the JOINing process.
2357 * Added to USERS command in silcd/command_reply.c to join the client,
2358 we didn't use to know about, to the channel after we've created
2359 a client entry for it. Also, for clienet we did know already still
2360 check whether it is on the channel or not and add it if not.
2362 * Removed silc_server_command_join_notify as the function and its
2365 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2367 * Changed the client's pending command handling to the same as the
2368 server's pending command handling. It is also now possible to
2369 execute command reply functions from other command reply
2370 function as the function callbacks for commands and command
2371 replies are one and same. The pending commands are not static
2372 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2373 in client connection context. Thus, pending commands are server
2374 connection specific as it is convenient.
2376 Changed the function silc_client_command_pending and
2377 silc_client_command_pending_del and added new function
2378 silc_client_command_pending_check. Removed the
2379 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2382 * Added cmd_ident, current command identifier, to the client
2383 connection context in lib/silcclient/client.h to keep track on
2384 command identifiers used in command sending. Client's command reply
2385 function handling now supports the mandatory command identifiers.
2387 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2388 funtions in client to fully support pending command callbacks.
2390 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2391 as one of the arguments to the application in the command reply
2394 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2395 before first releasing SILC but came back. Now it is removed again
2396 and should come back nomore. The FORWARDED flag was used only
2397 by the JOINing procedure by forwarding the command packet to router.
2398 Now, the JOINing procedure has been changed to more generic (due
2399 to various router environment issues) and FORWARDED is not needed
2400 anymore for anything. The protocol specification is yet to be
2403 Now, removed silc_server_packet_forward from server and the flag
2404 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2406 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2408 * Renamed NAMES command to USERS command. The NAMES was named that
2409 due to historical reasons. Now it is renamed. Also, rewrote
2410 parts of the USERS command. The nickname list is not sent anymore
2411 by the server. Only Client ID and mode lists are sent in the USERS
2412 command. Changed this also to the protocol specification.
2414 The client now resolves the names and stuff after it receives
2415 the USERS list from the server when joining to the channel.
2417 * WHOIS and IDENTIFY commands has been changed to support multiple
2418 Client ID's per command. One can now search for multiple users
2419 in the network by sending only one WHOIS or IDENTIFY command.
2420 Changed the code and the protocol specifications.
2422 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2423 uses silc_server_command_whois_parse to parse the request. */
2425 * If normal server, do not parse the WHOIS and IDENTIFY requests
2426 before sending it to the router. Saves some time.
2428 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2430 * Fixed JOIN command on client library. Wrong number of arguments
2431 used to crash the client.
2433 * Added silc_server_channel_has_global function to check whether
2434 channel has global users or not.
2436 * Added silc_server_channel_has_local function to check whether channel
2437 has locally connected clients on the channel.
2439 * The silc_server_remove_from_one_channel now checks whether the
2440 channel has global users or not after given client was removed from
2441 the channel. It also checks whether the channel has local clients
2442 on the channel anymore. If it does not have then the channel entry
2443 is removed as it is not needed anymore.
2445 * The silc_server_notify now checks on JOIN notify whether the joining
2446 client is one of locally connected or global. If it is global then
2447 the channel has now global users on the channel and that is marked
2448 to the channel entry. Also, it now saves the global client to
2449 global list who is joining and JOINs it to the channel. This is
2450 for normal server, that is.
2452 Changed silc_server_send_notify_on_channel,
2453 silc_server_packet_relay_to_channel and
2454 silc_server_packet_send_to_channel check if we are normal server
2455 and client has router set (ie. global client) do not send the
2456 message to that client, as it is already routed to our router.
2458 * Implemented LEAVE notify type handling in silc_server_notify
2461 * Tested LEAVE command in router environment successfully. Tested
2462 with two routers, two servers and two clients.
2466 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2468 * Implemented SIGNOFF notify type handling in silc_server_notify
2471 * silc_server_remove_id now removes the client entry from all channels
2472 it has joined and thusly sends SIGNOFF notify type.
2474 * Rewrote the NAMES list generation in server by removing two excess
2475 loops. The lists are created now inside one loop.
2477 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2479 * silc_server_remove_channel_user checks now also global list
2480 for channel and client.
2482 * silc_server_new_channel_user checks now both local and global
2483 list for channel and client. Fixed a bug in client id decoding.
2484 Used to decode wrong buffer.
2486 * silc_server_channel_message checks now both local and global
2487 list for channel entry.
2489 * Tested channel joining (hence JOIN) in router environment
2490 successfully. Tested with two routers, two servers and two
2493 * Tested channel message sending in router environment successfully.
2495 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Added silc_server_save_channel_key into server.[ch] to save the
2498 received channel key in Channel Key payload processing. It is
2499 also used in JOIN command reply handling.
2501 Equivalent function silc_client_save_channel_key added into
2502 client.[ch] into client library.
2504 * Changed JOIN command reply to send information whether the channel
2505 was created or not (is existing already) and the channel key
2506 payload. Changed protocol specs accordingly.
2508 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2509 the request was sent by ID and not by nickname. Crashed on
2512 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2515 now correctly save the received data.
2517 * silc_server_free_sock_user_data now notifies routers in the
2518 network about entities leaving the network.
2520 At the same time implemented functions silc_server_remove_id
2521 and silc_server_send_remove_id to receive and send REMOVE_ID
2522 packets. The packet is used to notify routers in the network
2523 about leaving entities. The ID removed will become invalid in
2526 * Added function silc_idlist_del_server into server. Removes and
2527 free's server entry from ID list.
2529 * silc_server_private_message function now checks, if we are router,
2530 that the destination ID really is valid ID, naturally.
2532 * In router when NEW_ID packet is received (for new client) the
2533 hash of the Client ID is saved in the ID Cache but the
2534 client->nickname is set to NULL, instead of putting the hash
2537 IDENTIFY command now also checks that client->nickname must be
2538 valid. If it is not if will request the data from the server who
2539 owns the client. Added new function
2540 silc_server_command_identify_check.
2542 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2543 to set the command to already allocated Command Payload.
2545 * Tested private message sending in router environment with two
2546 routers, two servers and two clients. Fixed minor bugs and now
2549 * Fixed segfault from client's NAMES command. Used to crash if
2552 * Forwarded packets must not be routed even if it is not destined
2553 to the receiver. Changed server code comply with this.
2555 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * Added `require_reverse_mapping' boolean value to ServerParams
2558 structure. If TRUE (not default) the server will require that
2559 the connecting host has fully qualified domain name.
2561 If the reverse mapping is not required and hostname could not be
2562 found the IP address is used as hostname.
2564 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2566 * Implemented version string checking to both client and server.
2567 The check is incomplete currently due to the abnormal version
2568 strings used in development version of SILC.
2570 * Changed all command functions in server to use the new
2573 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2575 * Changed char *data to unsigned char *data in ID Cache system to
2576 support binary data as ID Cache data. Changed code to support
2577 binary data in lib/silccore/idcache.c.
2579 * Renamed silc_server_packet_relay_command_reply to
2580 silc_server_command_reply as it is normal packet receiving
2581 function. Rewrote the function to accept command replys for
2582 servers and not only for clients.
2584 * Mark remote router always as registered server if we are connecting
2585 to it. Otherwise, commands sent by the router to us are ignored.
2587 * All ID List find routines now returns the ID Cache Entry pointer
2588 as well if requested.
2590 * WHOIS command works now in router environment, tested with two
2591 routers, two servers and two clients.
2593 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2594 in router environment (as it is almost equivalent to WHOIS) but
2595 hasn't been tested thoroughly. Added new functions:
2597 silc_server_command_identify_parse
2598 silc_server_command_identify_send_reply
2599 silc_server_command_identify_from_client
2600 silc_server_command_identify_from_server
2602 * Disabled route cache adding because adding two different ID's with
2603 same IP replaces the old cache entry thus giving wrong route.
2604 The entry->router->connection is always the fastest route anyway
2605 so route cache may not be needed. Of course, new routes maybe
2606 established after receiving the ID when the entry->router->connection
2607 might not be anymore the most optimal.
2609 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2611 * Add route cache for received ID for fast routing.
2613 * Added silc_server_packet_route to route received packet on router
2614 that is not destined to us.
2616 * Renamed silc_server_get_route to silc_server_route_get.
2618 * Added id_string and id_string_len fields into SilcServer to
2619 include encoded ServerID for fast comparing without excess
2620 encoding of the ID's.
2622 * Cleaned up WHOIS command on server side. Added following static
2625 silc_server_command_whois_parse
2626 silc_server_command_whois_check
2627 silc_server_command_whois_send_reply
2628 silc_server_command_whois_from_client
2629 silc_server_command_whois_from_server
2631 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2632 arguments in command replies. All command functions should be
2633 updated to use this macro.
2635 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2637 * Minor typo fixes on command reply handling on server.
2639 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2641 * Added silc_server_command_add_to_channel internal routine to add
2642 the client to the channel after router has created the channel and
2643 sent command reply to the server.
2645 * Added generic silc_server_send_command to send any command from
2648 * Use static buffer with ID rendering instead of duplicating data.
2650 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Fixed a channel user mode bug when joining to a channel server gave
2653 everybody channel founder rights, oops.
2655 * We mark ourselves as the router of the incoming server connection
2656 if we are router ourselves. This way we can check in some packet
2657 sending functions whether it is locally connected server. For
2658 incoming router connections we put NULL.
2660 * For router sending packets locally means now always sending the
2661 packet cell wide; to local clients and local servers. For normal
2662 server sending packet locally means sending it to only local
2665 * Fixed the JOIN command to really work in router environment. If the
2666 channel is created it is always created by the router. Router is
2667 also responsible of making the initial joining to the channel,
2668 sending JOIN notify to the sending server and distributing
2669 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2670 does not exist server doesn't do anything else but forward the
2671 command to the router which performs everything.
2673 * Added silc_server_send_channel_key function to send the Channel Key
2676 * Added silc_server_create_channel_key to create new channel key. The
2677 channel key is now re-generated everytime someone joins or leaves
2678 a channel, as protocol dictates. Note: channel->key_len is the
2681 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2684 packet_receive.[ch] to separate packet sending and receiving
2685 routines. The server.[ch] now includes everything else including
2686 actual packet processing (writing and reading data) and other
2689 Renamed silc_server_private_message_send_internal to
2690 silc_server_send_private_message. The routine is still though
2691 used only to relay private messages as server does not send
2692 private messages itself.
2694 Renamed silc_server_new_channel to silc_server_create_new_channel
2695 and added new function sicl_server_new_channel that handles the
2696 incoming New Channel packet. Added also new sending function
2697 silc_server_send_new_channel to send New Channel Payload.
2699 * Added new function silc_server_notify to process incoming notify
2700 packet to the server/router. Server may then relay the notify
2701 to clients if needed.
2703 * Added new function silc_server_new_channel_user to process incoming
2704 New Channel User packet. Router will redistribute the packet and
2705 send JOIN notify to its local clients and locally connected servers
2706 if needed. Normal server will send JOIN notify to its local client
2707 on same channel when received this packet. Added also corresponding
2708 sending function silc_server_send_new_channel_user to sent the
2711 * Added boolean route argument to send_notif_to_channel and
2712 packet_send_to_channel functions to attempt to route the packet
2713 if it is TRUE and send only locally if it is FALSE.
2715 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2717 * silc_server_replace_id now broadcasts the received replace ID
2718 packet if it is not broadcast packet already. The router must
2719 broadcast to inform other routers about changed ID.
2721 * Added backpointer to server's router into SilcServer context in
2722 silcd/server_internal.h.
2724 * Fixed silc_server_packet_broadcast to send correct broadcast
2727 * The channel key is now distributed to the local client as soon
2728 as it is received from the router (in router environment) so that
2729 no other packet may be sent for the channel until client has
2732 * silc_server_remove_channel_user now broadcasts the received
2733 Remove Channel User packet if it is not broadcast packet already.
2734 The router must broadcast to inform other routers about removed
2737 * Added users field into SilcPacketContext that is a reference count
2738 of the context. One can increase the reference count by calling
2739 silc_packet_context_dup which is now changed to just increase the
2740 reference count instead of duplicating the data. The reference
2741 count is decresed by calling silc_packet_context_free that will
2742 free the data after the reference count hits zero.
2744 For now on the packet context and everything allocated into it
2745 (including the raw packet from network) must be freed by calling
2746 the new silc_packet_context_free function. Added also new function
2747 silc_packet_context_alloc that must be used now to allocate the
2748 context. This also means that if a routine is asynchronous from
2749 silc_[client/server]_packet_parse_type the packet context must
2750 be duplicated by calling silc_packet_context_dup. Otherwise it
2751 gets free'd after silc_[client/server]_packet_parse_type returns.
2752 Also, one must remember that if packet is duplicated then its
2753 reference count must be decresed by calling the free function as
2754 many times as it was duplicated.
2756 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2757 from both client and server.
2759 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2761 * Made joining to a channel working in router environment.
2763 * Cleaned up JOIN command on server side and create function
2764 silc_server_command_join_channel internal routine to make the
2767 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Changed silc_command_pending list to SilcDList. Also, added
2770 `ident' field to SilcServerCommandPending structure to identify
2771 the reply and to call correct callback.
2773 Added silc_server_command_pending_check function to replace the
2774 corresnponding macro. The silc_command_pending list is not
2777 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2778 to set identifier to previously allocated Command Payload. It
2779 is used to set identifier for command when resending Command
2782 * Added silc_command_payload_encode_payload to encode Command
2783 Payload buffer from SilcCommandPayload structure.
2785 * Added silc_argument_payload_encode_payload to encode Argument
2786 payload buffer from SilcArgumentPayload structure.
2788 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2790 * Changed WHOIS command to support router connection on server side.
2791 The whois request is always sent to router unless the server is
2792 standalone server. After server has received the reply from the
2793 router will it send the reply to the client.
2795 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2796 broadcast received broadcast packet. The function is used only
2797 by router. The broadcast packet is always sent to the router's
2800 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2801 render given ID to printable string, for log files for example.
2803 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2805 * Made basic router to router connections working. At least they
2806 can now connect to each other but nothing really works the way
2807 they are supposed - yet.
2809 * Added new initiator token to RouterConnection configuration
2810 file in silcd/serverconfig.[ch]. It is used to tell whether we
2811 are the initiator to the remote router or whether we'll expect
2812 the other end to connect.
2814 * Moved registering of listener task to silc_server_init, hence
2815 the server starts listenning as soon as it is run, even if it
2816 does not have connections to other routers. Let's see how well
2819 * Changed default connection retry timeouts for more suitable in
2822 * Removed cipher and such arguments from silc_idlist_add_client
2823 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2824 Added new function silc_idlist_add_data to add the keys and stuff
2827 * Added SilcIDListData structure and added it to SilcClientEntry
2828 and SilcServerEntry as their first field in the structure. This
2829 way we can explicitly cast the ID entries to the SilcIDListData
2830 structure and get common data for the entries. In past, we had
2831 to first check what type of connection it is and then cast it to
2832 correct ID entry type. Now, we can directly cast the opaque
2833 pointer to the SilcIDListData (no matter what ID entry it actually
2834 is) and get the data needed.
2836 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2838 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2839 in some circumstances even if threre were timeout tasks, though not
2840 IO tasks, but tasks anyway. Now fixed.
2842 * Defined SilcServerConnection structure to hold connection specific
2843 stuff about directly connected servers and routers. The definition
2844 is currently in silcd/server_internal.h. I thought about having
2845 a bit more important role fro this struct but for now it is used
2846 only when connecting to other server (or router actually).
2848 * Added connecting retry support in server when connecting to
2849 router(s). The retry feature implement exponential backoff
2850 algorithm. Also, added SilcServerParams structure to hold default
2851 parameters for server. For now, it include these retry settings
2852 and are hard coded. After server is moded to be as Silc Server
2853 Library this structure will be more important.
2855 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2857 * Changed client librarys channel->clients table to SilcList and
2858 changed code accordingly.
2860 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2862 * Changed client's channel table to SilcList and changed code
2863 accordingly. Also changed SilcChannelClientEntry to include back-
2864 pointer to the channel so that client entry can use that structure
2865 as list as well and we have fast cross-reference to the channel.
2866 This change dramatically decreased the complexity of channel
2867 handling with client entry and vice versa (removed one extra
2868 loop when searching for channel entry from many functions).
2870 * Changed server->sim from table to SilcDList and changed code
2873 * NAMES command can now be used from user interface. It will show
2874 the user list on the channel, neatly.
2876 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2877 Code now saves realname of the user if it becomes available.
2879 * Renamed configure.in to configure.in.pre and made ./prepare
2880 script to automatically add correct version string to
2881 configure.in which it creates from configure.in.pre.
2883 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2885 * NAMES command reply now shows users mode with the nickname when
2888 * Moved silc_client_ch[u]mode[_char] functions from
2889 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2890 place sucks, they are utility functions and should be in some
2893 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2895 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2898 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * Added TRQ (efficient deque and list library) into lib/trq. This is
2903 a very good list library that is currently used in the SILC. Defined
2904 SilcList API over the library because I didn't like the API very
2905 much. See lib/trq/silclist.h for the API and examples of how to
2906 use the API. Fixed various places in the code to use the new
2907 SilcList API. The SilcList is meant for lists that has a structure
2908 already defined as a list. It is not suitable to add just some
2909 context to the list (in TRQ, the context is the list actually).
2911 So, I defined SilcDList that can be used for the purpose where
2912 predefined list structure does not exit. This can be used as
2913 such list. Now some context just can be added to the SilcDList.
2914 Currently this list is not used in the SILC just yet, though there
2915 are a lot places where this can replace dynamically allocated
2916 tables and I will fix these places, later, to use SilcDList.
2917 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2918 and use TRQ internally).
2920 Also fixed some annoying warning messages that the original TRQ
2921 code generated. Also minor changes to TRQ's Makefile.in.
2923 * Added support for querying by Client ID to both WHOIS and
2924 IDENTIFY commands into server, as required by the protocol.
2926 * Removed method function pointers from SilcBuffer structure. They
2927 weren't used to anything and just increased the context size for
2928 no good reason. This change also made silc_buffer_alloc and
2929 silc_buffer_free functions inline functions.
2931 * Disabled command flooding detection support until it's fixed so
2932 that it accepts commands in but does not execute them more than once
2935 * Added silc_net_localhost(), to return local hostname, into
2936 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2937 that must be initialized before calling silc_client_init.
2939 * Added new function: silc_server_send_notify_on_channels to send
2940 notify messages to all channels client has joined. It is assured
2941 that the message is sent only once per client.
2943 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2944 lib/silcutil/silcutil.[ch] as silc_format function. The new
2945 function is generic and is used by server as well, not only by
2946 the logging routines.
2948 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2949 the provided version string was not acceptable. Added new function:
2950 silc_ske_check_version into lib/silcske/silcske.h. The function
2951 must be implemented by the application (client or server) and it
2952 does not reside in the SKE library. The function checks the version
2953 string remote end sent.
2955 * Added back pointers (to opaque context and to SilcSocketConnection)
2956 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2958 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2959 duplicate packet context structure.
2961 * Changed `notify' client operation to send same arguments as client
2962 receives from server except for ID's. ID's are mapped to correct
2963 ID entry and that is returned. Also, if channel entry is not sent
2964 by server but the notify is for channel the channel entry is sent
2965 to application (otherwise application doesn't know that it is for
2966 channel (library gets it from packet's Destination ID)).
2968 * Added silc_client_remove_from_channels into client library to
2969 remove a client from all channels it has joined to. Used when
2970 received SIGNOFF notify from server. Added also new function
2971 silc_client_replace_from_channels to replace old ID entry with
2972 new ID entry on all channels. Used when received NICK_CHANGE
2975 * Fixed ID Cache list handling in silc_idlist_get_client in
2976 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2977 to get (or query) client by ID.
2979 * Updated TODO list.
2981 * Added connection authentication status message defined by the
2982 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2983 support for these into the code in client and server side.
2985 * Added generic function silc_client_send_command to send any command
2986 with variable argument list. Application should use this function
2987 to send commands if the command functions provided by the library
2988 does not suite for the application's user interface needs.
2990 * Added new `failure' client operation. Application is notified about
2991 received failure packet if client is executing a protocol. In this
2992 case the protocol's execution has failed.
2994 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2995 is required by the protocol.
2997 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2998 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3001 * Added status flag to SilcSKE object to indicate realtime status
3002 of the SKE protocol.
3004 * Application receives now exactly same command reply arguments as
3005 the library receives from server. However, if ID is received the
3006 corresponding ID entry is returned to the application (eg. Client
3007 ID is mapped to correct SilcClientEntry entry and that is returned).
3008 Changed command_reply client operation due to this change.
3010 * Changed all ID's in commands and in command replys as ID Payloads.
3011 Change affected both client and server side codes.
3013 All ID's sent in SILC network (with execption of ID's in SILC
3014 Packet header) are sent in ID Payload to support variable length
3017 * Server now notifies nick changes and notifies all clients on
3018 the channels about the new nickname (about the new Client ID,
3021 * Implemented CMODE command to change channel modes. Supports all
3022 channel modes defined by the protocol specs except ban and invite
3023 lists. (Also, private channel key mode is supported but support for
3024 setting private channel key in client is missing, thus, this mode
3025 has no effect on client side (except that server requires that the
3026 client uses private channel key and normal channel traffic does not
3029 Also, invite mode works per se, but INVITE command does not work
3030 yet correctly, so you can set channel as invite only channel but
3031 inviting clients to the channel does not work (it is yet to be
3032 thought what's the best way to do it).
3034 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3035 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3036 Implemented CUMODE command to change user's mode on the channel.
3037 Supports all modes defined by the protocol specs.
3039 * Added NAMES command reply to return users modes on the channel.
3041 * Removed unnecessary and slow ciphers from lib/silccrypt.
3043 * Set SO_KEEPALIVE option to connection sockets by default.
3045 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3047 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3048 redefined the Notify Payload into protocol specs.
3050 * Added silc_id_payload_parse_id to get ID directly from raw
3053 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3056 accept searching by Client ID as well.
3058 * Added support for LEAVE and SIGNOFF notify types in client library.
3060 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3061 to parse ID Payload from raw data.
3063 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Added flags parameter into silc_ske_assemble_security_properties
3066 function in lib/silcske/silcske.[ch].
3068 * Changed notify client operation to fit better for notify messages
3069 sent by server. The notify payload received from server is now
3070 passed to the application (after parsing it to SilcNotifyPayload).
3071 It is application's responsibility to retrieve the arguments
3072 from the payload and show the message the way it wants. The message
3073 sent by server is implementation specific.
3075 * Changed public keys to comply with the protocol specification.
3076 Old public keys are not supported anymore and are not compatible.
3078 * Removed nickname from Channel Payload as the latest draft removed
3079 it. The client must resolve the nickname from the NAMES command
3080 reply received when it joined the channel.
3082 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3084 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Fixed some errors in protocol specification drafts.
3088 * Created lib/silccore/silcnotify.c to implement Notify Payload
3089 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3090 generic payloads described by protocol specifications. The file
3091 includes implementations for ID Payload and Argument Payload.
3093 * Changed Command Payload implementation to use the new Argument
3094 Payload. Changed command_xxxx_payload to command_payload_xxxx
3095 to comply with SILC coding conventions.
3097 * Added suppport for Argument Payload handling in Notify Payload
3098 implementation as protocol requires it. Added the new support
3099 into server and client lib as well.
3101 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * Added support for multiple nicknames on same channel. [n] is
3104 added locally to the nickname if there are more than one same
3105 nicknames on the channel.
3107 * Server now sends all nicknames that matched WHOIS request.
3108 Client also shows the list received from server.
3110 * Added TOPIC command to client side. User can now set and show
3111 current topic on channel.
3113 * Added MOTD command to client and server. Also, server sends the
3114 motd when client connects to the server.
3116 * Changed version strings to comply ISO 8601.
3118 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Fixed protocol error handling in client library. It should now
3121 cope even if the SKE fails for some reason.
3123 * Made new protocol specification drafts for submitting to IETF.
3125 * Implemented TOPIC command to server in silcd/command.c.
3127 * Added two new notify types into lib/silccore/silcnotify.h:
3128 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3129 notify nickname change and topic setting/change on a channel.
3131 * API change of command_reply operation in client library. The
3132 application gets now the status type received from server as well.
3134 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3136 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3138 * Cras fixed and optimized the packet handling even further and
3139 it should work now. Minor change to the prototype of function
3140 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3142 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Added new function into lib/silcutil/silcschedule.[ch]:
3145 silc_schedule_with_fd to select() a specified fd. The function
3146 returns after timeout expires or data arrives or goes. The
3147 function is used by packet routines to wait that all data is
3148 received from network.
3150 * Fixed data reading from network in lib/silccore/silcpacket.c.
3151 The code now assures that all data is read from the fd and then
3152 continues packet processing. This was a bug fix since the code
3153 used to drop some data in some circumstances.
3155 * Added new function into lib/silcclient/client.[ch]:
3156 silc_client_start_key_exchange to start key exchange after
3157 connection has been established to server. The code internally
3158 now uses this funtion but its main purpose was to provide it
3159 for applications that perform their own connecting. After
3160 application has created a connection it merely calls this
3161 function to start the key exchange between client and server.
3162 The library takes care of everything else after that.
3164 Updated also lib/silcclient/README to explain the usage of
3167 * Do not send to application information that connection has
3168 been established. Application gets notified it by connect
3171 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3173 * Applied cras's patch to add silc_schedule_one function. The
3174 function runs scheduler once and returns.
3176 * Fixed the scheduler after cras messed it up. The timeout
3177 handling works now as it's supposed to work.
3179 * Added into lib/silccore/ silcnotify.h to include notify
3180 message types support. Changed silc_server_send_notify*
3181 functions, in server.[ch], to support those new notify types.
3182 Added the support for the notify types into client library,
3183 as well. Added new notify client operation into ops.h in
3186 * Changed silc_server_packet_send_to_channel to send normal
3187 packets instead of just channel message packets. The function
3188 is now used to send the notify packets to channels. It is not
3189 used to send channel message packets anymore, as server never
3192 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3193 va_arg()s as it seems to require it nowadays. I guess, if SILC
3194 is compiled with older va_arg() the new code should work anyway.
3196 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3198 * Splitted core library. Core library (lib/silccore) includes
3199 now only SILC protocol specific core (and common) components.
3200 Created new utility library (lib/silcutil) that includes more
3201 generic purpose stuff. The stuff for util library was taken
3202 from the old core library. This was minor and easy split.
3204 * Created SILC Client Library (lib/silcclient) that includes
3205 implementation of the SILC client without user interface. This
3206 was major move from silc/ directory. The code has been changed
3207 so that it is transparent towards the user interface. The
3208 silc/ directory includes now the same user interface as before
3209 and it uses the new client library. Read lib/silcclient/README.
3210 Basicly, the client library performs everything else related
3211 to SILC except user interface handling. Also, configuration
3212 files are considered to be part of user interface and library
3213 does not handle them.
3215 This change also changed a lot of structures, function naming etc.
3216 Most important change was that SilcClientWindow object was
3217 renamed to SilcClientConnection in the client library. Created
3218 also new file lib/silcclient/ops.h. Also added new files
3219 silc/local_command.[ch] and silc/client_ops.[ch].
3221 All these changes were made to make it easier for user interface
3222 designers to create what ever user interface for the SILC client
3225 It is also expected that the server will be moved to lib
3226 directory as well and SILC Server Library will be created;
3227 sometimes in the future.
3229 * Removed Local commands from lib/silccore/silccommand.h as
3230 they are application specific and new client library does not
3231 handle any of those anymore.
3233 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3234 old client implementation in silc/.
3236 * Added support for callback functions in SILC_LOG_* macros.
3237 Application can now set its own callbacks that will be called
3238 instead of using the default functions that will always print
3239 the debug messages to stderr (or stdout). Also, debugging can
3240 now be disabled by setting silc_debug to FALSE and re-enabled by
3241 setting it to TRUE. Note, that logging will still work even
3242 if debugging is disabled.
3244 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3245 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3246 silc_log_reset_debug_callbacks.
3248 * To enable debugging in silc client one must give now -d
3249 option on command line.
3251 * Changed silc_schedule_init to automatically allocate task queues
3252 if they are not allocated before calling it.
3254 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Added GMP 3.1 into math library.
3258 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3261 a channel in SILC network. The packet is used by servers and
3262 routers to notify other routers that user has left a channel.
3263 This little feature was missing until now. Added the feature
3264 to protocol specification as well.
3266 Added functions: silc_server_send_remove_channel_user and
3267 silc_server_remove_channel_user into server.[ch].
3269 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3270 lib/silccore/silcpacket.h. However, they are not implemented
3273 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Fixed joining to a channel and sending channel messages
3276 between server and router. The channel message sending should
3277 now work inside a cell.
3279 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Fixed the private message sending between server and router.
3282 The private message sending should now work inside a cell.
3284 * Added silc_server_replace_id into server.[ch] to replace
3285 existing ID in the SILC network.
3287 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3288 and silc_idlist_replace_server_id into idlist.[ch] in server.
3290 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Fixed the server to server connections. Server can again now
3293 connect to router. Router to router connections probably does
3296 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Added dynamic protocol registering support. Now protocols can
3299 registered and unregistered on the fly. Patch by cras.
3301 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Added lib/contrib directory to hold routines that some platforms
3304 don't have but are needed by SILC.
3306 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3307 into lin/contrib to provide getopt() and getopt_long() for
3308 those who don't have it.
3310 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Added AWAY command to client. When away message is set and
3313 client receives a private message packet the client automatically
3314 replies to the sender with the away message.
3316 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3317 bug seemed to be the cause of recent problems when compiling
3320 * Added version detection support to SKE protocol specification
3321 and added the new changes to the SKE implementation as well.
3322 There were other minor changes in the SKE protocol as well.
3324 Many changes in lib/silcske/silcske.[ch] and in
3325 lib/silcske/payload.[ch].
3327 * Added ^U functionality, clear input line. Patch from cras.
3329 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3331 * Mainly small bugfixes on core library. Fixed some debugging
3332 logging and buffer overflow in silclog.c.
3334 * Updated config.sub and config.guess on the distribution tree.
3336 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3338 * Added command lagging support in server. Client may execute
3339 commands now only once in two seconds.
3341 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3343 * Optimized packet reception. MAC computation and checking is now
3344 also more optimized. A lot previously duplicated code is now
3345 used as generic by both client and server.
3347 * Fixed key pair generation in clientutil.c
3349 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3351 * Added into lib/silccore/silcbufutil.[ch] new function;
3352 silc_buffer_realloc.
3354 * Moved generic packet sending/encryption functions to
3355 lib/silccore/silcpacket.[ch] from client and server. Some
3356 rewriting of the functions.
3358 * Moved all generic packet reception/decryption functions to
3359 lib/silccore/silcpacket.[ch] from client and server. The
3360 packet processing is now much cleaner in both client and server.
3361 These were major changes in both client and server.
3363 * Created many common functions in server to do packet sending.
3364 Previously code were duplicated a lot, this has been removed
3367 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Rewrote major parts of the ID cache system. Don't know
3370 whether it is better now or not but at least the API is more
3373 * Major rewrite on ID cache stuff on client because of the ID
3374 cache API changes. Added idlist.c to client.
3376 * Also major rewrite on ID cache stuff on server as well.
3377 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3378 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3379 in hand, instead they are all put into the ID cache system now.
3380 All server_idlist_* routines uses ID cache now instead of
3381 traversing its own lists (those lists does not exist anymore).
3382 SilcIDList though still exists. Also, SilcXXXEntry's are
3385 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Finally made the SKE implementation compliant to the protocol
3388 specification. All mp integers are now binary encoded as
3389 opposed being HEX encoded.
3391 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3394 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3395 functions: silc_[encode/decode]_pem. Also added function
3396 silc_encode_pem_file to PEM encode with newlines ('\n') for
3399 * SILC public keys are now encoded either PEM or binary. Same
3400 option is for private keys as well. By default private keys
3401 are binary encoded and public keys PEM encoded. Silly HEX
3402 encoding were removed.
3404 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3405 function to create fingerprints.
3407 * Fixed a bug in SHA1; does not change the original data anymore.
3409 * Partly implemented INFO command on client and server side.
3410 Fixed CLEAR command. Changes to SERVER command; show current
3411 server(s) when giving command without arguments. Added
3412 VERSION command to client.
3414 * Added check to server that unregistered connections cannot
3415 execute commands (unless it is specificly allowed).
3417 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Fixed screen refresh.
3421 * Fixed channel joining bug from client. On some circumstances
3422 client tried to join to a channel it had already joined.
3424 * Added public key verification process into client's protocol.c.
3425 The client now verifies the public key from user and saves
3426 it into ~./silc/serverkeys/ directory.
3428 Added into: clientutil.[ch]: silc_client_verify_server_key.
3430 * Changed SKE protocol's silc_ske_initiator_finish function
3431 to accept callback function that verifies the received public
3432 key. Removed old silc_ske_verify_public_key function.
3434 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3437 silc_pkcs_private_key[_data]_set.
3439 * Made the password and public authentication more cleaner in
3440 server's protocol.c.
3442 * Removed historic and obsolete protocol `channel_auth' from
3443 both client and server.
3445 * Removed wrong way of sending command status messages from
3446 server to client in server's command.c. The old way violated
3447 protocol specification.
3449 Changes to silccore/silccommand.[ch]: removed
3450 silc_command_encode_status_payload -> not needed anymore,
3451 changed silc_command_encode_payload_va to accept extra
3452 argument on variable argument list. The argument type must
3453 now be provided to the function. Also, added new function:
3454 silc_command_encode_reply_payload_va which is same as
3455 normal command_encode_payload_va except command status type
3456 is provided as extra argument.
3458 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Added ~./silc directory handling. The directory includes the
3461 public and private keys for the client.
3463 Added silc_client_check_silc_dir, silc_client_create_identifier
3464 and silc_client_load_keys.
3466 * Implemented SILC protocol compliant public key. Added public
3467 and private key saving to and loading from files.
3469 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3470 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3471 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3472 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3473 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3475 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3476 silc_pkcs_load_[public/private]_key.
3478 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Added silc_server_get_route (route.[ch]) to get connection
3481 data for the fastest route for given ID.
3483 * Implemented INVITE command on client and server. The command
3484 were re-defined in the SILC Protocol Specification and the
3485 implementation now complies with the specification.
3487 * Implemented PING command on client and server.
3489 * Implemented NAMES command on client and server. The server side
3490 supports currently only normal server not router server yet.
3491 Some changes to NAMES definition in SILC protocol specification.
3493 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Implemented LEAVE command on client and server.
3497 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3498 again. This change was made to the protocol as well. Server
3499 should not violate the protocol specification anymore.
3501 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3504 was tested. SOCKS4 was not but should work anyway.
