1 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added new SilcIDIP structure into the lib/silccore/id.h and
4 replaced the old `ip' fields from all SILC ID's to that type.
5 This is a step towards IPv6 support.
7 The silc_id_get_len takes now the ID as an extra argument.
8 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
9 both IPv4 and IPv6 based ID's.
11 The affected files are lib/silccore/id.[ch] and other files
12 around the tree using these routines.
14 * Removed the ID length arguments in server from various
15 silc_server_send_notify_* routines -> they are not needed
18 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
20 * Fixed memory leak in silc_encode_pem_file in the file
21 lib/silcutil/silcutil.c.
23 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
25 * Check minor version as well in the SKE. Affected files are
26 silcd/protocol.c and lib/silcclient/protocol.c.
28 * Added --identifier option to the server so that an identifier
29 can be when creating the public key for the server. Affected
30 file is silcd/silcd.c.
32 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
33 lib/silccrypt/silcpkcs.c.
35 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
37 * Register default ciphers and stuff when using -C option with
38 the server. Affected file sildc/silcd.c.
40 * Put back the servers public key filename format, it is better
41 than the new one. For now, the client keys are saved with the
42 new filename format. The affected file silc/client_ops.c.
44 * Implemented the Cipher API for the rest of the ciphers that
45 did not implement it or implemented it the wrong way.
47 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
49 * Register default ciphers and stuff when using the -S option
50 in the client. Affected file silc/silc.c. Same also when
51 creating new key pair with -C option.
53 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
55 * Fixed the silc_verify_public_key client operation function to
56 save the public keys differently. The fingerprint is now
57 used as filename and not the hostname. This way also the
58 client keys are saved uniquely and not with hostnames. The
59 affected file is silc/client_ops.c.
61 * Trimmed the silc_hash_fingerprint function to remove extra
62 whitespaces from the end of the fingerprint. The affected
63 file is lib/silccrypt/silchash.c.
67 * Added silc_cipher_register_default function to register all
68 default ciphers. It can be used when configuration files
69 does not exist and the application does not want any specific
70 ciphers in any specific order.
72 The SilcDList is now used as silc_cipher_list dynamically
73 allocated cipher list. Removed the static list all together
74 and now all ciphers must be allocated to the dynamic list.
75 The silc_cipher_alloc routine was changed to check only the
78 All silc_cipher_* routines that used to return int returns
81 The affected files lib/silccrypt/silccrypt.[ch].
83 * The same thing was done to silc_hash_* as for silc_cipher_*
84 routines. Affected files lib/silccrypt/silchash.[ch].
86 * The same thing was done to silc_pkcs_* as for silc_cipher_*
87 routines. Affected files lib/silccrypt/silcpkcs.[ch].
88 Added also silc_pkcs_[un]register[_default] functions.
89 Removed the data_context from the PKCS API.
91 * Added silc_hmac_register_default function to register default
92 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
93 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
94 to unregister all hmacs at once.
96 * Register the default ciphers, hash functions, PKCSs and HMACs
97 if client's configuration file does not exist. The affected
100 * The client did not load the hash functions from the SIM
101 modules at all. Added support for this. Affected file is
104 * When decoding public key with silc_pkcs_public_key_decode, check
105 the supported algorithm only if PKCS are registered. Affected
106 file lib/silccrypt/silcpkcs.c. The same was done with the
107 silc_pkcs_private_key_decode.
109 * Fixed the SILC List routines to keep the list always in order.
110 It used to change the list's order when traversing the list but
111 not it preserves the order. Affected file lib/trq/silclist.h.
113 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
115 * Added the client library to use the SilcSocketConnection's
116 reference counter (by silc_socket_dup) to prevent the bug that
117 the socket object may be freed underneath async operation.
119 * The name resolv library checking fixes in the configure.in.pre.
122 * Created new version of the protocol drafts for future
123 development. The -03 drafts are the ones that will be changed
124 in the trunk now and the -02 will remain as they are.
126 * Send list of CUMODE notifys to the router when announcing
127 the channel users to the router. Affected file silcd/server.c.
128 If the router receiving channel founder CUMODE for a channel
129 that already has channel founder it will send CUMODE notify
130 to the sender to remove the channel founder rights from the
131 announced client. Affected file silcd/packet_receive.c.
133 * The CUMODE notify may now use Server ID as well as the entity
134 who changes the mode. Updated protocool specs.
136 * Updated INSTALL and README files.
138 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
140 * New web pages in the http://silc.pspt.fi. The pages was
145 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
147 * Implemented the [DenyConnectin] config section in the server.
148 Added silc_server_config_denied_conn to check whether incoming
149 connection is denied. Affected file silcd/serverconfig.[ch].
151 * Do not check the ports when checking the incoming configuration
152 data if the port is 0, meaning any. Affected file is
153 silcd/serverconfig.c.
155 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
157 * Fixed buffer overflow in silc_string_compare in the file
158 lib/silcutil/silcutil.c.
160 * Fixed double free in silc_server_command_leave in the file
163 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
165 * Fixed the version checking in the server. Affected file is
168 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
170 * Fixed the configuration data fetching when accepting new
171 connections in the server. Affected file silcd/server.c.
173 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
175 * Added `sender_entry' argument to the function
176 silc_server_packet_relay_to_channel so that we can check
177 whether some destination actually belongs to the same route
178 the sender belongs (ie, we must not resend the packet to the
179 sender). Affected file silcd/packet_send.[ch].
181 * Added `servername' field to the SilcClientEntry in the server
182 to hold the name of the server where client is from. Affected
183 file is silcd/idlist.h.
185 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
187 * Moved the channel message encrypting in the router betwen
188 router connections from silc_server_channel_message to the
189 silc_server_packet_relay_to_channel since we want to check
190 whether we have anybody channel before encrypting anything.
191 Affected files silcd/packet_[receive/send].c.
193 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
195 * Fixed the [AdminConnection] server config section to support
196 multiple entries. Affected file silcd/serverconfig.c.
198 * Added support into the server to check the validity of the
199 incoming connection before executing any KE or authentication
202 * The connection configuration is now saved to the KE and
203 connection auth protocol contexts and not fetched anymore in
204 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
206 * The local hosts listenning address and port is also resolved
207 now when starting the server. We want to have the socket object
208 to include the real address and port for the listener. Added
209 new function silc_net_check_local_by_sock into the files
210 lib/silcutil/silcnet.[ch].
212 * Fixed a broadcast bug in server -> do not broadcast if we
215 * Fixed a routing bug. Do not route broadcast packets ever.
216 Broadcast packets must be processed always and not routed since
217 they may be destined to some other host than yourself and thus
218 would get routed without no good reason. Affected file is
221 * Added function silc_server_config_is_primary_route to check
222 whether primary router connection has been configured (a router
223 configuration that we are initiating). If there is not, we
224 will assume that there is only two routers in the SILC network
225 and we will use the incoming router connection as our primary
226 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
228 * Changed the order of the broadcasting. Broadcast _after_ the
229 packet has been processed not before. Affected file is
232 * Fixed a [ClientConnection] parsing bug. The port was never
233 parsed correctly thus resulting to port 0. Affected file
234 silcd/serverconfig.c.
236 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
237 argument and did not set the broadcast packet flag. Affected
238 file silcd/packet_send.c. Fixed same bug in the function
239 silc_server_send_notify as well.
241 * If we receive NEW_ID packet for our own ID in the server, ignore
244 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
248 * Removed the nickname from the Private Message Payload.
249 Updated the code and the protocol specs.
251 * Updated protocol specs for submitting to the IETF.
253 * Tweaked the Random Number Generator a bit. Affected file
254 lib/silccrypt/silcrng.c. Exported a new function
255 silc_rng_[global]_add_noise which can be used to add more
258 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
260 * Do not parse packets with different timeout when protocol
261 is active -> may cause problem with rekey. Affected file
264 * When server receives signoff notify it must not create
265 new channel key if the client is on any channels since the
266 sender of the signoff notify will create it.
268 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
270 * Added printing of error messages during SKE protocol from the
271 failure packet sent by server during SKE. Affected file
274 * Removed the client's failure_callback handling with timeout
275 and handle it immediately when received.
277 * The SKE library returned wrong type in SUCCESS and FAILURE
278 packets. They must be 32 bit MSB not 16 bit MSB.
280 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
282 * Ok, rewrote the logic of the re-key and now it seems to work.
283 I tested it on high traffic with frequent re-keys without
284 problems. Added hmac_receive (and renamed hmac to hmac_send)
285 in SilcClientConnection in lib/silcclient/client.h and
286 in SilcIDListData in silcd/idlist.h. Also, removed the
287 SilcPacketParserContext's cipher and hmac fields as they are
288 not needed anymore and actually caused some problems when
289 the ciphers and hmac's changed underneath the packet parser.
291 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
293 * If re-key protocol is active then process the incoming packets
294 synchronously since we must assure that icoming packets encrypted
295 with the old key is processed before the new keys is set to
296 use. This is true other packets than for REKEY packets.
297 Affected file silcd/server.c. The same was done to client library
298 as well, affected file lib/silcclient/client.c.
300 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
302 * Fixed bug in client and server to accept the force send if
303 the packet is send from silc_[server/client]_packet_process
304 function. Otherwise the packets are never delivered, oops.
306 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
308 * Disable force sending of packets when REKEY protocol is active.
309 We must assure that no packet is sent directly when rekey is
310 performed. All packets must be sent through packet queue.
311 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
312 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
313 function is silc_[server/client]_packet_send_real to check
316 * Replaced the SIM paths from example config files to
317 /usr/local/modules. Also, make install creates now
318 /usr/local/silc/logs directory to hold all the SILC server
321 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
323 * Made the configure.in.pre work on Solaris. Patch by salo.
325 * Made all ciphers compatible with non-x86 machines. Defined
326 CBC mode macros into lib/silccrypt/ciphers_def.h.
328 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
330 * Fixed the make install.
332 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
334 * When MAC computation fails the silc_packet_decrypt returned 0
335 even though it was supposed to return -1. Fixed this. The
336 affected file is lib/silccore/silcpacket.c.
338 * Do not replace the config files in /etc/silc (in make install)
339 if they already exist. Affected file ./Makefile.am.
341 * Do not send re-key packets immediately but through packet queue.
342 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
344 * Changed silc_net_check_host_by_sock to return FALSE if the
345 IP/DNS could not be resolved. Though, it returns the IP address
346 now even if it could not resolve it (but returns also FALSE).
347 Affected file lib/silcutil/silcnet.[ch].
349 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
351 * Added silc_pkcs_decode_identifier to decode the public key's
352 identifier. Affected file lib/silccrypt/silpkcs.[ch].
353 Added also silc_pkcs_free_identifier. Added also new context
354 SilcPublicKeyIdentifier.
356 * Added -S option to the silc client. It is used to dump the
357 contents of the specified public key file.
359 * Changed the PKCS api to return the public key length when
360 setting the public key.
362 * Fixed a fatal bug in the public and private key file loading.
363 Affected file lib/silccrypt/silcpkcs.c.
365 * Execute the packet parsing for client with zero (0) timeout
366 if the protocol is active. Affected file silcd/server.c.
368 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
370 * Made the key generation options to the silcd program. Added
371 -C option, equivalent to client's option.
373 * Added new [ServerKeys] config section to the server. It
374 configures the server's public and private key.
376 * Defined generic Public Key Payload into the protocol
377 specification to send specific type of public keys and
380 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
381 public key or certificate.
383 * Implemented the GETKEY command to the server and to the
384 client library and on user interface.
386 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
388 * Made preliminary `make install' work.
390 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
392 * Added SilcServerRekey context into silcd/idlist.h.
394 * Added the PFS support as defined in the specification to the
395 SKE protocol. Affected files lib/silcske/*.c.
397 * Added `ske_group' field to the SilcServerRekey context to hold
398 the number of the SKE group that is used with PFS in re-key.
399 Affected file silcd/idlist.h.
401 * Added PFS re-key support to the server. Affected file is
404 * Added silc_protocol_cancel to cancel execution of the next
405 state of the protocol. Affected file is
406 lib/silccore/silcprotocol.[ch].
408 * Added the re-key support with and without PFS to the client
409 library. Re-key is performed once in an hour, by default.
411 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
412 Added silc_client_rekey_callback and silc_client_rekey_final.
413 Affected files are lib/silcclient/protocol.[ch] and
414 lib/silcclient/client.[ch].
416 * Removed the `hmac_key' and `hmac_key_len' fields from the
417 SilcClientConnection structure; not needed. Affected file is
418 lib/silcclient/client.h.
422 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
424 * Do not ask whether user wants to use the negotiated private key
425 for private messages, just use it. Affected file is
426 silc/local_command.c.
428 * Added `send_enc_key' and `enc_key_len' fields to the
429 SilcIDListData structure since they are needed in the re-key
430 phase. Affected file is silcd/idlist.[ch].
432 * Implemented the simple re-key protocol into the server.
433 Affected files silcd/server.c and silcd/protocol.[ch]. The
434 re-key will be performed once in an hour, by default.
436 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
437 Added silc_server_rekey, silc_server_rekey_callback and
438 silc_server_rekey_final.
440 * Removed Tunneled flag from the protocol. Updated the code
441 and the specifications.
443 * Adde `pfs' field to the SilcIDListData to indicate whether
444 the PFS is to be performed in the re-key. Affected file is
447 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
449 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
450 int64 of at least the xintXX size. If void * is less that 4
451 bytes uint32 * will be used. Defined bool as boolean.
453 * Changed _ALL_ unsigned long and unsigned int to uint32,
454 unsgined short to uint16 in the source tree.
456 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
457 not handle clients that has entry->data.registered == FALSE.
458 They are not in the network anymore. Affected file is
461 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
463 * Implemented the sending of the SERVER_SIGNOFF notify in the
464 server. Affected file is silcd/server.c.
466 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
467 Added also silc_notify_payload_encode_args into the
468 lib/silccore/silcnotify.[ch].
470 * Implemented ther SERVER_SIGNOFF notify handling in the server.
471 Affected file silcd/packet_receive.c.
473 * Implemented the SERVER_SIGNOFF notify handling in the client
474 library. Affected file lib/silcclient/client_notify.c. Also,
475 implemnted the printing of the SERVER_SIGNOFF info to the
476 application. Affected file silc/client_ops.c.
478 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
479 if the deleting was successful. Affected file silcd/idlist.[ch].
481 * Added support for public key authentication in the connection
482 authentication protocol in the client library. Affected file
483 lib/silcclient/protocol.c.
485 * Changed the server's silc_idlist_get_clients_by_* interface
486 to support already allocated array so that new entries may be
487 added to pre-allocated array. Affected file silcd/idlist.[ch].
488 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
491 * All command reply functions in the server now calls the
492 pending command callback even if error occured. This way the
493 error will be delivered to the client as well. Affected files
494 silcd/command.c and silcd/command_reply.c.
496 * Fixed INFO command to return local server's info if no server
497 was provided. Affected file lib/silcclient/command.c.
499 * Removed RESTART command for good. Updated the code and the
502 * Rewrote parts of the task system. It is a bit simpler now.
503 Removed unsued task priorities. The affected files are
504 lib/silcutil/silctask.[ch].
506 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
508 * Moved the USERS printing from the library to the application.
509 Affected files lib/silcclient/command.c and silc/client_ops.c.
511 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
515 * Added channel key re-key support. The re-key is perfomed
516 only by the router and is done once in an hour. Added `rekey'
517 field to the SilcChannelEntry in the server. Affected files
518 silcd/server.c and silcd/idlist.h.
520 * Added silc_task_unregister_by_context into the file
521 lib/silcutil/silctask.[ch].
523 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
525 * Added SILC_UMODE_GONE mode to indicate when the client is not
526 present in the SILC network. Added also support to the local
527 command AWAY that will set this mode. Added support of showing
528 "xxx is gone" in WHOIS command. The USERS command shows the
531 * Fixed setting server and router operator privileges in the
532 server's UMODE command. Affected file silcd/command.c.
534 * Merged the SKE KE1 and KE2 payloads into one payload. The
535 new KE payload is equivalent to the old KE2 payload.
537 Cleaned up the SKE Start Payload parsing. It now uses the
538 simple buffer unformatting to do the parsing. A lot faster
541 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
542 to the SKE that is used to indicate whether both of the SKE
543 parties should perform authentication. By default only the
544 responder performs authentication. By setting this flag also
545 the initiator must do authentication. By default it is unset
546 since in normal SKE case, client to server connection, only
547 the responder should do authentication. When doing SKE between
548 two clients both should perform authentication. Updated the
549 code and the protocol specs.
551 * A little fix to IDENTIFY command in the server. Search the
552 client first by hash not nickname. Affected file is
555 * Fixed the silc_client_close_connection to support closing
556 the client to client connections wihtout deleting too much
557 data. Affected file lib/silcclient/client.c.
559 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
560 are received if protocol used to be active but is not anymore
561 the application would crash due to NULL pointer dereference.
562 Affected files silcd/server.c and lib/silcclient/client.c.
564 * Added `hash' field to the SilcClientConnection to include
565 the hash function negotiated in the SKE protocol.
567 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
568 to set the channel founder authentication data. A client can
569 claim the founder rights later by providing the authentication
570 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
571 This way the channel founder can regain the channel founder
572 privileges even it is left the channel. This works only on
573 local server and the client must be connected to the same
574 server to be able to regain the founder rights. Updated the
575 protocol specs accordingly.
577 Added support to the CMODE command in the client to set the
578 founder auth data. Read the README to see how to set it.
580 Added support to the CUMODE command to claim the founder
581 rights. Read the README to see how to do it.
583 Added support for the founder authentication to the Channel
584 Entry in the server. Affected file silcd/idlist.h.
586 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
587 server's CMODE command. Affected file silcd/command.c.
589 * Added the following new functions into lib/silccore/silcauth.[ch]:
590 silc_auth_get_method and silc_auth_get_data.
592 * The server now saves the remote hosts public key to the
593 SilcIDListData pointer. Affected file silcd/protocol.c.
595 * The normal server now does not remove the channel entry from
596 the cache if the founder authentication data is set. It used
597 to remove it if the founder was the last one on the channel on
598 the server and left the channel. The auth data is saved and
599 if the channel is re-joined later the old entry is used with
600 the old auth data. Affected files silcd/command_reply.c and
603 * Removed the `pkcs' field from the SilcIDListData structure
604 in the server; it is not used. Affected file silcd/idlist.h.
606 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
608 * Fixed packet processing on slow links. Partial packets were
609 never re-processed because the incoming data buffer was cleared
610 by the application. Application must not directly clear the
611 sock->inbuf, the packet processing routines handle it. Fixed
612 this in client library and in server.
614 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
616 * Fixed the WHOIS and IDENTIFY send reply function to really
617 check whether to send list or just one entry. Affected file
620 * Cleaned up the LEAVE command's channel key distribution. The
621 affected file silcd/command.c.
623 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
624 can enforce the channel mode as well. In that case the ID
625 includes the ID of the server. The code now enforces the
626 mode change if the router have different mode than the server.
628 * The notify client operation with CMODE_CHANGE notify can now
629 return NULL client_entry pointer if the CMODE was not changed
630 by client. Application must check for this.
632 * Added <Server ID> argument to INFO command to support server
633 info fetching by Server ID.
635 * Added silc_server_announce_get_channel_users to get assembled
636 packets of channel users of the specified channel. Affected
637 file silcd/server.[ch].
639 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
640 was freed underneath the ID Cache.
642 * Re-announce clients when the server received CHANNEL_CHANGE
643 notify from the router. Affected file silcd/packet_send.c.
645 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
647 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
648 crashed since it did not handle the fact that there is no cipher
649 called "3" and didn't check the error condition. Now fixed.
651 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
652 flag. It can be used to send message requests.
654 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
656 * Implemented the RESTART command in the client.
658 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
659 notice type messages. Added notice printing to the user
662 * The channel keys are not re-generated if the channel's mode
663 is PRIVKEY, ie private key on the channel exists. Affected
664 files silcd/server.c and silcd/command.c.
666 * Fixed a little bug in channel message delivery when channel
667 private keys are set in the server. Affected file is
670 * Changed the setting on channel->on_channel = TRUE from the
671 silc_client_save_channel_key to the JOIN command reply. The
672 key payload is not received if the private channel key is set.
673 Affected file lib/silcclient/command_reply.c and the
674 lib/silcclient/client_channel.c.
676 * When the CMODE_CHANGE notify is sent and the channel private
677 key mode is removed the channel key must be re-generated in
678 other cells as well. Added this support for the router in the
679 silcd/packet_receive.c.
681 * Added new local command NOTICE to send notice message on
682 channel. Affected file silc/local_command.[ch].
684 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
686 * Added new local command ME to the client. It is used to send
687 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
688 some action. Affected file silc/local_command.[ch].
690 * Changed channel_message and private_message client operations
691 to deliver the message flags to the application. Added also
692 the `flags' arguments to the silc_client_send_channel_message
693 and silc_client_send_private_message functions. Affected file
696 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
698 * Redefined the Private Message Payload to support private message
699 keys and to support the new private message flags. Updated
700 the protocol specs. Flags makes it possible to have for example
703 * Added new type SilcPrivateMessagePayload and defined an API
704 for it in the lib/silcclient/silcprivate.[ch].
706 * Tested private message private keys successfully. Tested the
707 private message key set, unset and list commands with the new
710 * Redefined the Channel Message Payload to include the channel
711 message flags (equal with private message flags) to support
712 for example CTCP style messages.
714 * Defined some of the message (for channel and private message)
715 flags. Updated the protocol specs and added the flags to the
716 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
718 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
720 * Added SilcKeyAgreementStatus type to the key agreement routines
721 to indicate the current status and error if one occured.
722 The status types are defined in the lib/silcclient/silcapi.h.
724 * Added new local command KEY that is used to set and unset private
725 keys for channels, set and unset private keys for private messages
726 with remote clients and to send key agreement requests and
727 negotiate the key agreement protocol with remote client. The
728 key agreement is supported only to negotiate private message keys,
729 it currently cannot be used to negotiate private keys for channels,
730 as it is not convenient for that purpose.
732 * Fixed a minor pending callback setting bug in the function
733 silc_client_get_client_by_id_resolve, now the function works.
734 Affected file lib/silcclient/idlist.c.
736 * Added function silc_net_get_local_port to get local bound
737 port by socket. Added to lib/silcutil/silcnet.[ch].
739 * Added `sockets' and `sockets_count' fields to the SilcClient
740 object. They hold the sockets of the listenning sockets in
741 the client. Listenning sockets may be for example the key
742 agreement server. Affected file lib/silcclient/client.[ch].
743 Added functions the silc_client_add_socket and the
744 silc_client_del_socket. They are exported to the application
747 * Added ~./silc/clientkeys to support other client's public keys.
749 * Renamed verify_server_key client operation to verify_public_key
750 and added one argument to indicate the type of the connection
751 (server, client etc.).
753 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * Added silc_server_connection_auth_request to handle the
756 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
757 silcd/packet_receive.[ch].
759 * Added silc_server_send_connection_auth_request into the
760 silcd/packet_send.c to send the connection auth request packet.
762 * Cleaned up the silcd/protocol.c a bit and fixed some memory
765 * Fixed the public key authentication in responder side in the
766 server. The `auth_data' pointer includes the SilcPublicKey
767 not the path to the public key. Affected file silcd/protocol.c.
769 * Implemented the public key authentication in the initiator side
770 in the server. Affected file silcd/protocol.c.
772 * Removed the [RedirectClient] config section from the server
773 configuration. Is not needed and I don't want to implement it.
775 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
777 * Cleaned up the CMODE command in the server. It now works
778 correctly and supports all the modes defined in the protocol.
779 Affected file is silcd/command.c.
781 * Added `hmac_name' field to the SilcChannelEntry in the server
782 to hold the default HMAC of the channel. It can be set when
783 creating the channel (with JOIN command). Affected files
786 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
787 type to indicate the change of the current cipher and hmac
788 on the channel. Client can safely ignore the <cipher> argument
789 (if it chooses to do so) since the CHANNEL_KEY packet will
790 force the channel key change anyway. The <hmac> argument is
791 important since the client is responsible of setting the new
792 HMAC and the hmac key into use.
794 * Fixed the CMODE command in the client library as well.
796 * Tested CMODE command in router environment successfully.
798 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
800 * Show the version of the remote client (or server) when connecting
801 to the server. It is logged to the log file. Affected file
804 * Fixed the KILLED notify handling in the client library. The
805 client must be removed from all channels when receiving the
808 Also, do not remove the client entry when giving the KILL
809 command but when the KILLED notify is received.
811 * Removed silc_idlist_find_client_by_nickname from the server.
812 Not needed anymore. Affected files silcd/idlist.[ch].
814 * Implemented the CHANNEL_CHANGE notify type handling to the
815 server. Affected file silcd/server.c.
819 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
821 * Added silc_server_send_notify_invite to send the INVITE
822 notify between routers.
824 * Implemented the INVITE command correctly to the server.
826 * Implemented the INVITE notify type handling in the server.
828 * Implemented the INVITE command to the client library and on the
831 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
833 * Added function silc_server_get_client_resolve to find the
834 client entry by ID from all ID lists and then resolve it
835 (using WHOIS) if it cannot be found. Affected file is
838 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
840 * Implemented the BAN command to the client library.
842 * The JOIN command in the server now checks the invite list
845 * Changed the silc_command_reply_payload_encode_va and the
846 silc_command_payload_encode_va to support that if argument is
847 NULL it ignores and checks the next argument. Affected file
848 lib/silccore/silccommand.c.
850 * Added silc_server_send_notify_ban to send the BAN notify
851 type between routers.
853 * Chaned the silc_notify_payload_encode to support that if
854 argument is NULL it ignores and checks the next argument.
855 Affected file lib/silccore/silcnotify.c.
857 * Tested ban lists in router environment successfully.
859 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
861 * Implemented BAN command to the server, in silcd/command.[ch].
863 * Removed the BAN and INVITE_LIST modes from the CMODE command
866 * Added function silc_string_match to regex match two strings.
867 Affected files lib/silcutil/silcutil.[ch].
869 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
871 * Redefined parts of the SilcChannelEntry in the server to support
872 the new ban and invite lists.
874 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
876 * Redefined the INVITE command. The same command can be used to
877 invite individuals to the channel but also to manage the invite
878 list of the channel (to add to and remove from the invite list).
879 Updated the protocol specs.
881 * Added new command SILC_COMMAND_BAN that can be used to manage
882 the ban list of the channel. Updated the protocol specs.
884 * Removed the channel modes: the SILC_CMODE_BAN and the
885 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
886 in the CMODE command. The equivalent features are now available
887 using INVITE and BAN commands. Updated the protocol specs.
889 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
890 in the network about change in the current ban list. The notify
891 type is not used by the client.
893 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
894 support the invite lists.
896 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Added new function silc_string_regexify that converts string
899 including wildcard characters into regex string that can
900 be used by the GNU regex library. Added into the file
901 lib/silcutil/silcutil.[ch].
903 Added silc_string_regex_combine to combine to regex strings
904 into one so that they can be used as one regex string by
905 the GNU regex library. Added into the file
906 lib/silcutil/silcutil.[ch].
908 Added silc_string_regex_match to match two strings. It returns
909 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
911 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
913 * Imported GNU regex to the soruce tree into lib/contrib.
914 Fixed some compiler warning from the regex.c.
916 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
918 * Fixed MOTD command in the server to work in router environment.
920 * Fixed the MOTD command in the client library to support
921 the server argument in the command.
923 * Added `nickname_len' argument to the silc_idlist_add_client
924 in the server, as the `nickname' argument may be binary data
927 * Added silc_idlist_get_channels to return all channels from
930 * Implemented LIST command to the server. Affected file is
933 * Implemented the LIST command to the client library and on the
936 * Added [<user count>] argument to the LIST command reply.
937 With private channels the user count is not shown.
939 * Updated TODO and README.
941 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
943 * The client entry's data.registered must be TRUE even with
944 global client entry on global client list. The data.registered
945 is used to check whether the client is anymore in the network,
946 for example with WHOWAS command so it must be valid.
948 * Fixed the WHOWAS command in the server. It now actually works
949 in router environment. Added function into silcd/command_reply.c
950 silc_server_command_reply_whowas_save.
952 * Added silc_idlist_purge function to the silcd/idlist.c
953 to periodically purge the ID Cache.
955 * Fixed INFO command in the server. It works now in router
956 environment. Added <server name> argument to the INFO command
957 reply. Updated the protocol specs.
959 * Fixed minor bug in silc_idcache_purge to not purge if the
960 expire value is zero.
962 * Fixed various bugs in WHOIS and IDENTIFY command handling as
963 they were buggy because of the WHOWAS information.
965 * Fixed local command MSG to handle the async resolving of
966 the remote client properly. It used to fail the first MSG.
967 Affected file silc/local_command.c.
969 * Added `data_len' field to SilcIDCache context.
971 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
973 * Update TODO. Todo in commands in the server.
975 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
977 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
978 used by routers as broadcast packet to inform other routers
979 about the changed user mode.
981 Implemented the notify handling in the server. Affected file is
982 silcd/packet_receive.c. Added the function
983 silc_server_send_notify_umode to the silcd/packet_send.[ch].
985 * Added new generic Channel Payload and deprecated the New Channel
986 Payload. The New Channel Payload is now the generic Channel
989 * Added new argument `mode' to the silc_server_send_new_channel
990 as it is required in the Channel Payload now.
992 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
993 and created a new and real SilChannelPayload to represent the
994 new generic Channel Payload. Implemented the encode/decode
995 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
997 * Added silc_server_get_client_channel_list to return the list
998 of channels the client has joined for WHOIS command reply.
999 Affected file silcd/server.[ch].
1001 * Implemented the channel list sending in the WHOIS command reply
1002 in server and in the client.
1004 Implemented the channel list displaying on the user interface
1005 as well. Affected file silc/client_ops.c.
1007 * Added silc_channel_payload_parse_list to parse list of Channel
1008 Payloads. It returns SilcDList list of SilcChannelPayloads.
1009 Client for example can use this function to parse the list of
1010 channels it receives in the WHOIS command reply. The caller
1011 must free the list by calling silc_channel_payload_list_free.
1012 Affected files lib/silccore/silcchannel.[ch].
1014 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1016 * Added one new argument <user mode> to the WHOIS command reply
1017 to return the mode of the user in SILC. Updated the protocol
1020 Implemented it to the server and client.
1022 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1024 * Fixed the mode printing on the user interface on joining.
1025 Affected file silc/client_ops.c.
1027 * Implemented the UMODE command and user modes in general to the
1028 client library and to the user interface.
1030 * Implemented the UMODE command to the server.
1032 * The server now sends UNKNOWN_COMMAND error status if client sends
1033 unknown command. Affected file silcd/command.c.
1035 * All server commands now handle the command identifier the right
1036 way when sending the command reply to the client. The client can
1037 use to identify the command replies with the identifier.
1039 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1041 * Added silc_server_get_client_route to resolve the route to
1042 the client indicated by the client ID. Affected file is
1045 * Added silc_server_relay_packet as general function to relay
1046 packet to arbitrary destination. This deprecates functions
1047 like _send_private_message_key, _relay_notify etc. Affected
1048 file is silcd/packet_send.[ch].
1050 Removed silc_server_send_key_agreement,
1051 silc_server_send_private_message_key and
1052 silc_server_packet_relay_notify functions from the file
1053 silcd/packet_send.[ch].
1057 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1058 server. Affected file silcd/packet_receive.[ch].
1060 * Implemented the KILL command to the client. Implemented the
1061 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1062 Affected files lib/silcclient/command[_reply].c and
1063 lib/silcclient/client_notify.c. Implemented the KILL notify
1064 printing in the user inteface.
1066 * Fixed a lot silc_parse_nick memory leaks from the client
1067 library in the file lib/silcclient/command.c.
1069 * Changed the silc_server_send_notify_on_channels's `sender'
1070 argument from SilcSocketConnection to SilcClientEntry to
1071 check the sender as entry and not as connection object and not
1072 to send to the client provided as argument. The affected file
1073 is silcd/packet_send.[ch].
1075 * The notify packets that are destined directly to the client used
1076 to not to be processed by the server. Now changed that and the
1077 server processes all notify packets. After relaying the packet
1078 to the client the notify packet is processed in the server.
1080 * The silc_server_free_client_data now checks whether there is
1081 pending outgoing traffic for the client and purges the data to
1082 the network before removing the client entry.
1084 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1086 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1087 an client is killed from the SILC Network. Updated the protocol
1090 Added new function silc_server_send_notify_killed to the
1091 silcd/packet_send.[ch].
1093 * Added function silc_server_packet_relay_notify to relay notify
1094 packets that are destined directly to a client. In this case
1095 the server does not process the notify packets but merely relays
1096 it to the client. Affected file silcd/packet_send.[ch].
1098 Added also silc_server_packet_process_relay_notify to check
1099 whereto relay the notify. Affected file is
1100 silcd/packet_receive.[ch].
1102 * Implemented the KILL command to the server.
1106 * Added the backup schema desgined last fall to the protocol
1107 specs for everyone to see. The specification is in the
1108 *-spec-xx.txt draft and the packet type definitions for the
1109 backup routers is in *-pp-xx.txt draft. Thusly, added also
1110 new packet type SILC_PACKET_CELL_ROUTERS.
1112 * A big security problem in the implementation discovered. The
1113 signoff of an client did not cause new channel key generation
1114 which it of course should've done. The channel keys must be
1115 always re-generated when client leaves (or signoffs) the channel.
1116 The silc_server_remove_from_channels funtion now handles
1117 the channel key re-generation.
1119 * Added `sender' argument to the silc_server_send_notify_on_channels
1120 to not to send the client provided as argument. Affected file
1121 silcd/packet_send.[ch].
1123 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1125 * Implemented OPER and SILCOPER commands into the server and
1128 * Added silc_auth_verify and silc_auth_verify_data to verify
1129 the authentication directly from the authentication payload.
1130 It supports verifying both passphrase and public key based
1131 authentication. Affected file lib/silccore/silcauth.[ch].
1133 * Added `hash' field to the SilcIDListData structure. It is the
1134 hash negotiated in the SKE protocol. Affected file is
1137 * Slight redesigning of the SilcAuthPayload handling routines.
1138 Do not send SilcPKCS but SilcPublicKey as argument.
1140 * Implemented the public key authentication support to the
1141 serverconfig. The public key is loaded from the provided path
1142 and saved as authentication data to void * pointer. Thus,
1143 changed the unsigned char *auth_data to void *auth_data;
1145 * Fixed SHUTDOWN command to send the reply before the server
1146 is shutdown. :) Affected file silcd/command.c.
1148 * Fixed fatal bug in CONNECT command. The hostname was invalid
1149 memory and server crashed. Affected file silcd/command.c.
1151 * Fixed fatal bug in CLOSE command. The server_entry became
1152 invalid but was referenced later in the command. Affected file
1155 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1157 * Fixed fatal bug in failure packet handling. Server ignored
1158 the failure and thus crashed when it came.
1162 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1165 that the command may be executed only once in (about) 2 seconds.
1166 The old SILC_CF_LAG flag is same but allows command bursts up
1167 to five before limiting.
1169 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1170 server code. Various commands now includes the CF_LAG_STRICT
1171 flag to disallow any kind of miss-use of the command.
1173 * Fixed the silc_buffer_unformat to not to allocate any data
1174 if the length of the data is zero. It used to allocate the
1175 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1177 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1179 * Changed the format of AdminConnection configuration section
1180 in the server. Added username of the admin to the format.
1181 Affected files silcd/serverconfig.[ch].
1183 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1184 to return admin configuration data by host, username and/or
1187 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1189 * Implemented WHOWAS command to the server. Added the functions:
1191 silc_server_command_whowas_parse,
1192 silc_server_command_whowas_send_reply,
1193 silc_server_command_whowas_from_client and
1194 silc_server_command_whowas_from_server
1196 * Added <Client ID> argument to the WHOWAS command reply. Updated
1197 the protocol specs accordingly.
1199 * Implemented WHOWAS command and command_reply to the client
1202 Implemented the WHOWAS printing on the user interface.
1204 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1206 * Added new argument to the WHOWAS command reply, the real name.
1207 It is an optional argument. Updated the protocol specs.
1209 * Added SilcIDCacheDestructor callback that is registered when
1210 the SilcIDCache is allocated. The callback is called when
1211 an cache entry in the ID Cache expires, or is purged from the
1212 cache. Added into lib/silccore/idcache.[ch].
1214 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1215 to destruct the client entries when the cache entry expires.
1216 Other ID Cache's in server and in the client library ignores
1219 * If the ID Cache entry's `expire' field is zero then the entry
1220 never expires. Added boolean `expire' argument to the
1221 silc_idcache_add function in the lib/silccore/idcache.[ch].
1222 If it is TRUE the default expiry value is used.
1224 * Added silc_server_free_client_data_timeout that is registered
1225 when client disconnects. By default for 5 minutes we preserve
1226 the client entry for history - for WHOWAS command.
1228 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Added support to the server to enforce that commands are not
1231 executed more than once in 2 seconds. If server receives
1232 commands from client more frequently, timeout is registered
1233 to process the commands. Affected file silcd/command.c.
1234 Added new function silc_server_command_process_timeout.
1236 * Changed NICK_NOTIFY handling in client library to check that
1237 if the client's nickname was changed, so there is no need to
1238 resolve anything from the server.
1240 * Removed error printing from the WHOIS and IDENTIFY commands.
1241 If error occurs then it is ignored silently in the client library.
1242 The application, however, may map the received error to
1243 human readable error string. The application currently maps
1244 the NO_SUCH_NICKNAME error to string.
1246 * Made the command status message public to the application. Moved
1247 them from lib/silcclient/command_reply.c to
1248 lib/silcclient/command_reply.h. The application can map the
1249 received command status to the string with the
1250 silc_client_command_status_message function.
1252 * Added check to the server to check that client's ID is same
1253 as the Source ID in the packet the client sent. They must
1256 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1258 * Added dist-bzip hook to the Makefile.am to make bzip2
1259 compressed distributions.
1261 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1263 * Server now enforces the maximum length for the nickname and
1264 the channel as protocol specification dictates. 128 bytes for
1265 nickname and 256 bytes for channel name.
1267 * Moved the WHOIS printing to the application. The client libary
1268 does not print out the WHOIS information anymore, the application
1269 must do it. Renamed silc_client_command_reply_whois_print to
1270 the silc_client_command_reply_whois_save.
1272 The client's idle time is also sent to the application now, and
1273 the idle is shown on screen.
1275 * Added silc_client_command_reply_identify_save to save the
1276 received IDENTIFY entries.
1278 * Do not check for channel private keys in message sending and
1279 reception if the channel does not have the PRIVKEY mode set.
1280 Affected file lib/silclient/client_channel.c.
1282 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1284 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1285 just surfaced after chaning the JOIN procedure.
1287 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Added silc_client_get_clients_by_list to get client entries
1290 from Client ID list, that is returned for example by JOIN
1291 and USERS command replies. The application should use this
1292 function for example when JOIN command reply is received to
1293 resolve the clients already on the channel (library does not
1294 do that anymore as USERS command reply is not used in the JOIN
1295 procedure anymore). Affected files lib/silcclient/silcapi.h and
1296 lib/silcclient/idlist.c.
1298 * JOIN command reply and USERS command reply returns now SilcBuffer
1299 pointers instead of unsigned char pointers when returning
1300 the client list and mode list.
1302 * Added <Client ID> argument to the JOIN command reply, mainly
1303 for the server to identify for which client the command was
1304 originally sent. Updated protocol specs accordingly.
1306 * Added SilcDlist private_key pointer to the SilcChannelEntry
1307 in the client to support the channel private keys. Affected
1308 file is lib/silcclient/idlist.h.
1310 * Added SilcChannelPrivateKey argument to the function
1311 silc_client_send_channel_message so that application can choose
1312 to use specific private ke if it wants to. If it is not provided,
1313 the normal channel key is used, unless private keys are set.
1314 In this case the first (key that was added first) is used
1315 as the encryption key.
1317 * Implemented the support for channel private key handling.
1318 Implemented the following functions:
1320 silc_client_add_channel_private_key,
1321 silc_client_del_channel_private_keys,
1322 silc_client_del_channel_private_key,
1323 silc_client_list_channel_private_keys and
1324 silc_client_free_channel_private_keys
1326 Affected file lib/silcclient/client_channel.c.
1328 * Added the support for the private keys in the channel message
1329 sending and encryption and in the message reception and
1330 decryption. Affected funtions are
1331 silc_client_send_channel_message and silc_client_channel_message.
1333 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1335 * Added SKE's key verify callback to the client library's
1336 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1338 * Removed the statement that server (or router) must send USERS
1339 command reply when joining to the channel so that the client
1340 knows who are on the channel. Instead, the client list and
1341 client's mode list is now sent in the JOIN command reply to the
1342 client who joined channel. This is better solution.
1344 * Added function silc_server_get_users_on_channel and function
1345 silc_server_save_users_on_channel to the silcd/server.[ch].
1347 * Removed function silc_server_command_send_users from the
1350 * Do not show topic on the client library anymore. The topic is
1351 sent in the command reply notify to the application and the
1352 application must show the topic now.
1354 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1356 * Added client searching by nickname hash into the IDENTIFY and
1357 WHOIS commands in the server as they were clearly missing from
1358 them. Affected file is silcd/command.c.
1360 * Fixed a bug in private message receiving in the client library.
1361 The remote ID was freed and it wasn't supposed, now it is
1364 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1366 * Minor fix to the channel payload; allocate the data area, as it
1367 needs to be of specific length.
1369 * If the key agreement port is zero then the operating
1370 system will define the bound port. Affected files are
1371 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1373 * Added new function silc_channel_payload_decrypt into the file
1374 lib/silccore/silcchannel.[ch].
1376 * Moved the channel message etc, check from silc_packet_decrypt
1377 to applications. The library calls now a generic
1378 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1379 when the packet is either normal or special. This was done to
1380 allow more wide range of checking that was not allowed when
1381 the code was in library. Now applications can do virtually any
1382 checks to the packet and return to the library the decision how
1383 the packet should be processed. Affected files are
1384 lib/silccore/silcpacket.[ch].
1386 Added silc_server_packet_decrypt_check to the server and
1387 silc_client_packet_decrypt_check to the client library.
1389 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1390 to send with specified source and destination information.
1392 * Channel message delivery between routers was broken after the
1393 channel key distribution was fixed earlier. The channel key
1394 was used be to distributed to other routers as well which is not
1395 allowed by the protocol. Now this is fixed and channel keys
1396 really are cell specific and the channel message delivery between
1397 routers comply with the protocol specification.
1399 * Fixed various commands in server to check also the global list
1400 for the channel entry and not just the local list. The affected
1401 file silcd/command.c.
1403 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1405 * Added assert()s to buffer formatting and unformatting routines
1406 to assert (if --enable-debug) when error occurs. Affected
1407 file: lib/silcutil/silcbuffmt.c.
1409 * Changed to auto-reconnect to check whether the remote host is
1410 router and register the re-connect timeout if it is. It used
1411 to check that whether we are normal server, but router must do
1412 auto-reconnect with another router as well. Affected file
1415 * Removed the [<key len>] option from CMODE command as the cipher
1416 name decides the key length, nowadays. See the defined ciphers
1417 from the protocol specification.
1419 * Added [<hmac>] option to the CMODE command to define the HMAC
1420 for the channel. Added SILC_CMODE_HMAC channel mode.
1422 * Added [<hmac>] option for the JOIN command so that user can
1423 select which HMAC is used to compute the MACs of the channel
1426 * Added Hmac field to the Channel Message Payload. The integrity
1427 of plaintext channel messages are now protected by computing
1428 MAC of the message and attaching the MAC to the payload. The
1429 MAC is encrypted. Now, it is clear that this causes some
1430 overhead to the size of the packet but rationale for this is that
1431 now the receiver can verify whether the channel message decrypted
1432 correctly and also when private keys are set for the channel the
1433 receiver can decrypt the packet with several keys and check from
1434 the MAC which key decrypted the message correctly.
1436 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1437 lib/silccrypt/silccipher.[ch].
1439 * Added silc_hash_len to return the digest length into the
1440 lib/silcrypt/silchash.[ch].
1442 * Rewrote parts of Silc Channel Payload interface in the
1443 lib/silccore/silcchannel.[ch]. The encode function now also
1444 encrypts the packet and parse function decrypts it.
1446 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1448 * Fixed a minor formatting bug in the SKE's key material processing.
1449 It actually might have processed the keys wrong way resulting
1452 * Redefined the mandatory HMAC algorithms and added new algorithms.
1453 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1454 and hmac-md5 truncated to 96 bits. The mandatory is now
1455 hmac-sha1-96. Rest are optional (including the one that used
1456 to be mandatory). Rationale for this is that the truncated HMAC
1457 length is sufficient from security point of view and can actually
1458 make the attack against the HMAC harder. Also, the truncated
1459 HMAC causes less overhead to the packets. See the RFC2104 for
1462 * Added new [hmac] configuration section. The SKE used to use
1463 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1464 is of course wrong. The official names that must be proposed in
1465 the SKE are the ones defined in the protocol specification
1466 (hmac-sha1-96 for example). The user can configure any hmac
1467 using any hash function configured in the [hash] section. At
1468 least, the mandatory must be configured.
1470 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1472 * Added HMAC list to the SKE proposal list. It has now both
1473 hash algorithm list and HMAC list. This makes the protocol
1474 incompatible with previous versions. The SKE now seems to work
1475 the way it is supposed to work, for the first time actually.
1477 * Defined plain Hash algorithms to the protocol specification.
1480 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1482 * Implemented support for key agreement packets into the server.
1483 Added functions silc_server_key_agreement and
1484 silc_server_send_key_agreement. Other than these functions,
1485 server has nothing to do with this packet.
1487 * Added support for private message key packets into the server.
1488 Added functions silc_server_private_message_key and
1489 silc_server_send_private_message_key.
1493 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1494 called in the protocol's final callback instead in the END
1495 protocol state. This makes a little more sense and in the same
1496 time in client we can use the same protocol routines for normal
1497 key exchange and to key agreement packet handling as well.
1499 * Added to both client's and server's KE protocol context the
1500 SilcSKEKeyMaterial pointer to save the key material. We will
1501 bring the key material to the protocol's final callback by doing
1502 this. The final callback must free the key material.
1504 * Added SKE's packet_send callback into client's KE protocol
1505 context so that the caller can choose what packet sending function
1506 is used. This way we can use different packet sending when
1507 doing normal SKE when doing key agreement packet handling (in
1508 the key agreement packet handling we do not want to encrypt
1511 * Implemented the responder side of the key agreement routines
1512 in the client. The client can now bind to specified port and
1513 accept incoming key negotiation. The key material is passed
1514 to the application after the protocol is over.
1516 * Implemented the processing of incoming Key Agreement packet
1517 in the client. Added function silc_client_key_agreement to
1520 * Implemented the intiator side of the key agreement routines
1521 in the client. The client can now initiate key agreement with
1522 another remote client. The key material is passed to the
1523 application after the protocol is over.
1525 * Created client_keyagr.c to include all the key agreement
1528 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1529 SILC_TASK_CALLBACK except that it is not static.
1531 * Created client_notify.c and moved the Notify packet handling
1532 from the client.[ch] into that file.
1534 * Created client_prvmsg.c and moved all private message and
1535 private message key routines from the client.[ch] into that file.
1537 * Create client_channel.c and moved all channel message and
1538 channel private key routines from the client.[ch] into that file.
1540 * Changed silc_client_get_client_by_id_resolve to resolve with
1541 WHOIS command instead of IDENTIFY command, in the file
1542 lib/silclient/idlist.c.
1544 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1546 * Implemented the SKE's responder side to the Client library.
1548 * When FAILURE is received to the protocol do not trust it
1549 blindly. Register a timeout to wait whether the remote closes
1550 the connection as it should do it, only after that process the
1551 actual failure. This was changed to both client and server.
1553 * Added client_internal.h to include some of the structures
1554 there instead of client.h in lib/silcclient/.
1556 * Added function silc_task_unregister_by_callback to unregister
1557 timeouts by the callback function.
1559 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1561 * Some "Incomplete WHOIS info" errors has been appearing on the
1562 log files. Took away the entry->userinfo check from WHOIS
1563 reply sending. The entry->userinfo is now " " if client did not
1564 provide one. I thought this was fixed earlier but something
1565 is wrong still. Let's see if the error still appears.
1567 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1569 * Fixed a minor bug in the login when the channel key is
1570 re-generated in the server. It used to generate the key in
1571 wrong order and thus caused problems in the channel traffic.
1573 * Fixed a minor bug in channel key distsribution after
1574 KICK command. The key was not sent to the router even though
1577 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1579 * Added silc_ske_process_key_material_data as generic routine
1580 to process any key material as the SILC protocol dictates. The
1581 function is used by the actual SKE library but can be used by
1582 applications as well. This relates to the private message keys
1583 and the channel private keys since they must be processed the
1584 same way the normal SILC session keys. The protocol dictates
1585 this. Affected files: lib/silcske/silcske.[ch].
1587 Added also silc_ske_free_key_material to free the
1588 SilcSKEKeyMaterial structure.
1590 * Defined silc_cipher_set_key function to set the key for
1591 cipher without using the object's method function. The affected
1592 files: lib/silccrypt/silccipher.[ch].
1594 * Implemented silc silc_client_add_private_message_key,
1595 silc_client_add_private_message_key_ske,
1596 silc_client_del_private_message_key,
1597 silc_client_list_private_message_keys and
1598 silc_client_free_private_message_keys functions in the
1601 Added functions silc_client_send_private_message_key to send
1602 the Private Message Key payload and silc_client_private_message_key
1603 to handle incoming Private Message Key payload.
1605 * Added Cipher field to the Private Message Key payload to set
1606 the cipher to be used. If ignored, the default cipher defined
1607 in the SILC protocol (aes-256-cbc) is used.
1609 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1611 * Removed lib/silcclient/ops.h file.
1613 Redefined parts of the SILC Client Library API. Created new
1614 file silcapi.h that deprecates the ops.h file and defines the
1615 published Client Library API. Defined also private message key
1616 API and channel private key API into the file.
1618 This is the file that the application must include from the
1619 SILC Client Library. Other files need not be included by
1620 the application anymore.
1622 * Added new key_agreement client operation callback and also
1623 defined the Key Agreement library API for the application.
1625 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1627 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1628 is used by clients to request key negotiation between another
1629 client in the SILC network. If the negotiation is started it
1630 is performed using the SKE protocol. The result of the
1631 negotiation, the secret key material, can be used for example
1632 as private message key.
1634 Implemented the Key Agreement payload into the files
1635 lib/silccore/silauth.[ch].
1637 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1639 * Redefined ciphers for the SILC protocol. Added some new ciphers
1640 and defined the key lengths for the algorithms. Changed the
1641 code accordingly. The default key length is now 256 bits.
1643 * Fixed SKE key distribution function silc_ske_process_key_material
1644 when the key length is more than 128 bits. The default key
1645 length in SILC is now 256 bits.
1647 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1648 to indicate unsupported algorithm.
1650 * Renamed rijndael.c to aes.c and all functions as well.
1652 * Fixed a long standing channel key setting bug in client library.
1653 Weird that it has never surfaced before.
1655 * Fixed bug in channel deletion. If the entire channel is removed
1656 then it must also delete the references of the channel entry
1657 from the client's channel list as the client's channel entry and
1658 the channel's client entry share same memory.
1660 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1662 * Implemented CONNECT and SHUTDOWN commands in the client.
1664 * Implemented CLOSE command to the client.
1666 * Added the function silc_idlist_find_server_by_name into the
1667 files silcd/idlist.[ch].
1669 Added the function silc_idlist_find_server_by_conn into the
1670 files silcd/idlist.[ch].
1672 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1674 * DIE command was renamed to SHUTDOWN. Updated the both code
1677 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1678 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1680 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1683 * Added function silc_server_create_connection function to create
1684 connection to remote router. My server implementation actually
1685 does not allow router to connect to normal server (it expects
1686 that normal server always initiates the connection to the router)
1687 so the CONNECT command is only good for connecting to another
1690 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1692 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1693 or some other client was kicked from the channel.
1695 Implemented the handling of the notify type to both client
1698 Implemented silc_server_send_notify_kicked to send the KICKED
1699 notify. It is used to send it to the server's primary router.
1701 * Implemented the KICK command into server and client.
1703 * Added `query' argument to the silc_idlist_get_client function
1704 to indicate whether to query the client from server or not if
1707 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1708 to indicate that the client is not channel founder.
1712 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1714 * Removed the rng context from SilcPacketContext structure and
1715 changed that the packet routine uses the Global RNG API.
1717 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1719 * Added support for quit message that client can "leave" on the
1720 channel when it quits the SILC. It is ditributed inside the
1721 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1723 Added silc_server_free_client_data that will take the
1724 signoff message as argument.
1726 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1728 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1730 * Updated parts of the protocol specification to keep it up
1733 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1735 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1736 payloads in one packet.
1738 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1739 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1740 use now the new List flag.
1742 * Also deprecated the following packet types: REPLACE_ID,
1743 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1745 * Added list support for Notify packet in server.
1747 * Added silc_server_send_notify_channel_change to send the
1748 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1749 the silc_server_send_replace_id.
1751 * Added silc_server_send_notify_nick_change to send the
1752 NICK_CHANGE notify type. Deprecates the function
1753 silc_server_send_replace_id.
1755 * Added silc_server_send_notify_join to send the JOIN notify type.
1756 Deprecates the function silc_server_send_new_channel_user.
1758 * Added silc_server_send_notify_leave to send LEAVE notify type.
1759 Deprecates the function silc_server_send_remove_channel_user.
1761 * Added silc_server_send_notify_cmode and
1762 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1763 types. Deprecates the silc_server_send_set_mode function.
1765 * Added SERVER_SIGNOFF notify type to indicate that server has
1766 quit. This means that all clients on the channel from that
1767 server will drop. This can be also used when netsplit happens.
1769 Deprecated REMOVE_ID packet type since it is not needed anymore
1772 Added silc_server_send_notify_server_signoff to send the
1773 SERVER_SIGNOFF notify type. Deprecates the function
1774 silc_server_send_remove_id.
1776 Added also silc_server_send_notify_signoff to send the
1777 SIGNOFF notify type.
1779 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1780 SILC protocol from this day on. Changed the protocol
1781 specification as well.
1783 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1784 notify type. It is used between routers to notify about
1785 topic changes on a channel.
1787 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1790 * Partly updated the protocol specification to comply with the
1791 changes now made. It is still though a bit outdated.
1793 * The JOIN notify type now takes one extra argument <Channel ID>.
1794 The packet used to be destined to the channel but now the
1795 JOIN type may be sent as list thus it is impossible to
1796 destine it to any specific channel. By adding this argument
1797 it is again possible.
1799 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1801 * Added CREDITS file. The CHANGES and CREDITS file will appear
1802 in the distribution as well.
1804 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1806 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1807 types in the server's silcd/packet_receive.c.
1809 * Implemented CMODE and CUMODE to work in router environment.
1811 * Fixed minor encoding and decoding buglet from the
1812 lib/silccore/silcmode.c.
1814 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1817 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1819 * Changed all SilcConfigServer* and silc_config_server* to
1820 SilcServerConfig* and silc_server_config*, respectively.
1823 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1825 * Associated the ID (client or server ID) to the Authentication
1826 Payload to avoid any possibility of forging. Updated the
1827 protocol specification and the code accordingly.
1829 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1831 * The RSA key length is now save to the RsaKey context in the
1832 key generation process in lib/silccrypt/rsa.c. The key length
1833 is now used to figure out the maximum size of the block allowed
1834 to be encrypted/signed.
1836 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1837 is equivalent to the silc_mp_mp2bin but does not allocate any
1840 * Changed silc_mp_mp2bin API to take length argument. If it is
1841 non-zero then the buffer is allocated that large. If zero, then
1842 the size is approximated using silc_mp_sizeinbase, which however
1845 * Created Global RNG API which is global RNG that application can
1846 initialize. After initializing, any routine anywhere in the
1847 code (including library) can use RNG without allocating a new
1848 RNG object. This was done to allow this sort of use of the
1849 RNG in code that has no chance to allocate RNG object. All
1850 applications currently allocate this and many routines in the
1851 library use this. Affected file lib/silccrypt/silcrng.[ch].
1853 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1854 it to use the Global RNG API.
1856 * Defined Authentication Payload into protocol specification that
1857 is used during SILC session to authenticate entities. It is
1858 used for example by client to authenticate itself to the server
1859 to obtain server operator privileges.
1861 Implemented this payload into the lib/silccore/silcauth.[ch].
1862 Implemented also routines for public key based authentication
1863 as the new protocol specification dictates.
1865 Moved definitions of different authentication methods from
1866 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1868 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1869 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1870 silc_pkcs_verify_with_hash functions into the file
1871 lib/silccrypt/silcpkcs.[ch].
1873 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1875 * The client entry's userinfo pointer must be always valid.
1876 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1877 will fail since it requires the userinfo. Now, the userinfo
1878 is allocated as "" if actual userinfo does not exist. Actually,
1879 it must exist and it is totally Ok to drop client connections
1880 that does not announce the userinfo. However, we will make
1881 this workaround for now.
1883 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1884 to return the remote port by socket.
1886 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1888 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1889 SILC_SERVER_PENDING_EXEC and added an new macro
1890 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1891 data or when error occurs while processing the pending command.
1893 Added new argument `destructor' into silc_server_command_pending
1894 and to the SilcServerCommandPending object. This destructor is
1895 now called after calling the pending callback or if error occurs
1896 immediately. If error occurs the actual pending callback won't
1897 be called at all - only the destructor. The destructor may be
1898 NULL if destructor is not needed.
1900 All this applies for client library code as well. Similar
1901 changes were made there as well for the pending commands.
1903 In the client, the application must now allocate the
1904 SilcClientCommandContext with the silc_client_command_alloc
1907 * Added reference counter to the SilcServerCommandContext. Added
1908 function silc_server_command_alloc and silc_server_command_dup
1911 Same type of functions added to the client library for the same
1914 * Removed the cmd_ident from IDListData away since it is now
1915 global for all connections. It is the command identifier used
1916 in command sending and with pending commands. The affected file
1919 * Added reference counter to the SilcSocketConnection objecet to
1920 indicate the usage count of the object. The object won't be
1921 freed untill the reference counter hits zero. Currently only
1922 server uses this, and client ignores it. The client must be
1923 set to use this too later. The affected files are
1924 lib/silccore/silcsockconn.[ch]. Added also the function
1925 silc_socket_dup to increase the reference counter.
1927 This was mainly added because it is possible that the socket
1928 is removed underneath of pending command or other async
1929 operation. Now it won't be free'd and proper DISCONNECTING
1930 flags, etc. can be set to avoid sending data to connection that
1931 is not valid anymore.
1933 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1934 the connection. After that it sets SILC_SET_DISCONNECTED.
1935 It is, however, possible that the socket data is not still freed.
1936 The silc_server_packet_process now checks that data is not
1937 read or written to connection that is DISCONNECTED. The socket
1938 get's freed when the reference counter hits zero.
1940 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1942 * Changed the client operation API: channel_message operation's
1943 `sender' is now the client entry of the sender, not the nickname
1944 and the `channel' is the channel entry, not the channel name.
1946 In the private_message operation the `sender' is now also the
1947 client entry of the sender not the nickname.
1949 Affected file is lib/silcclient/ops.h and all applications
1950 using the client operations.
1952 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1954 * Moved the calling of ops->connect() from connect_to_server_final
1955 into receive_new_id functin since that is the point when the
1956 client is actually allowed to send traffic to network. The
1957 affected file is lib/silcclient/client.c.
1959 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1961 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1962 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1963 (if needs broadcasting) instead of broadcasting the packets one
1964 by one which would make a burst in the network traffic.
1966 * Added `broadcast' argument to the functions in silcd/server.[ch]
1967 silc_server_create_new_channel[_with_id] to indicate whether
1968 to send New Channel packet to primary router.
1970 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1972 * Added new function into the silcd/server.[ch] files:
1973 silc_server_create_new_channel_with_id to create new channel with
1974 already existing Channel ID.
1976 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1977 lib/silccore/silcpacket.h. This packet is used t send list of
1978 Set Mode payloads inside one packet. Server uses this to set
1979 the modes for the channels and clients on those channels, that it
1980 announced to the router when it connected to it. The protocol
1981 specification has been updated accordingly.
1983 * The silc_server_new_channel did not handle the packet coming
1984 from normal server as it normally does not send that. However,
1985 when it announces its channels it does send it. Implemented
1986 the support for that.
1988 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1989 into the file lib/silccore/id.h.
1991 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1993 * Fixed memory leaks in the functions silc_idlist_del_client,
1994 silc_idlist_del_channel and silc_idlist_del_server in the file
1995 silcd/idlist.c. All of those leaked like a sieve.
1997 * Fixed some small memory leaks in the client's function
1998 silc_client_notify_by_server.
2000 * Added functions into silcd/server.c: silc_server_announce_clients,
2001 silc_server_announce_channels and silc_server_announce_server.
2002 These functions are used by normal and router server to announce
2003 to its primary router about clients, channels and servers (when
2004 router) that we own. This is done after we've connected to the
2007 These functions effectively implements the following packet types:
2008 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2009 and SILC_PACKET_NEW_ID_LIST.
2011 * Added new functions into the silcd/packet_receive.[ch]:
2012 silc_server_new_id_list, silc_server_new_channel_list and
2013 silc_server_new_channel_user_list to handle the incoming
2014 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2016 * Added support of changing Channel ID in the function
2017 silc_server_replace_id. If the server that announces a channel
2018 to the router already exists in the router (with same name but
2019 with different Channel ID), router is responsible to send
2020 Replace ID packet to the server and force the server to change
2021 the Channel ID to the one router has.
2023 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2024 client that the Channel ID has been changed by the router. The
2025 normal server sends this to the client. Client must start using
2026 the new Channel ID as the channel's ID.
2028 Implemented handling of this new type into lib/silcclient/client.c
2029 into the function silc_client_notify_by_server.
2031 * Added new function silc_idlist_replace_channel_id into the files
2032 silcd/idlist.[ch] to replace the Channel ID.
2034 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2036 * Call silc_server_command_identify_check always when processing
2037 the IDENTIFY command in silcd/command.c
2039 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2042 send keepalive packets. The packet can be sent by clients,
2043 servers and routers.
2045 Added function silc_socket_set_heartbeat into the file
2046 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2047 If not set, the heartbeat is not performed. The actual
2048 heartbeat is implemented in the low level socket connection
2049 library. However, application is responsible of actually
2052 Added silc_server_send_heartbeat to send the actual heartbeat
2053 packet into silcd/packet_send.[ch]. Server now performs
2054 keepalive with all connections.
2056 * Added silc_task_get_first function into lib/silcutil/silctask.c
2057 to return the timeout task with shortest timeout. There was a bug
2058 in task unregistration that caused problems. TODO has been
2059 updated to include that task system must be rewritten.
2061 * The client library will now resolve the client information when
2062 receiving JOIN notify from server for client that we know but
2063 have incomplete information.
2065 * Rewrote parts of silc_server_remove_from_channels and
2066 silc_server_remove_from_one_channel as they did not remove the
2067 channel in some circumstances even though they should've.
2069 * Encryption problem encountered in server:
2071 The LEAVE command used to send the Channel Key packet to the
2072 router immediately after generating it. However, the code
2073 had earlier sent Remove Channel user packet but not immediately,
2074 ie. it was put to queue. The order of packets in the router
2075 was that Channel Key packet was first and Remove Channel User
2076 packet was second, even though they were encrypted in the
2077 reverse order. For this reason, MAC check failed. Now, this
2078 is fixed by not sending the Channel Key packet immediately but
2079 putting it to queue. However, this is more fundamental problem:
2080 packets that are in queue should actually not be encrypted
2081 because packets that are sent immediately gets encrypted
2082 actually with wrong IV (and thus MAC check fails). So, packets
2083 that are in queue should be encrypted when they are sent to
2084 the wire and not when they put to the queue.
2086 However, the problem is that the current system has not been
2087 designed to work that way. Instead, the packet is encrypted
2088 as soon as possible and left to the queue. The queue is then
2089 just purged into wire. There won't be any fixes for this
2090 any time soon. So, the current semantic for packet sending
2093 o If you send packet to remote host and do not force the send
2094 (the packet will be in queue) then all subsequent packets to the
2095 same remote host must also be put to the queue. Only after the
2096 queue has been purged is it safe again to force the packet
2099 o If you send all packets immediately then it safe to send
2100 any of subsequent packets through the queue, however, after
2101 the first packet is put to queue then any subsequent packets
2102 must also be put to the queue.
2104 Follow these rules and everything works fine.
2106 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Added new function silc_server_remove_clients_by_server to
2109 remove all client entries from ID list when the server connection
2110 is lost. In this case it is also important to invalidate all
2111 client entires as they hold the invalid server entry. This
2112 fixes fatal bug when server has lost connection and will reconnect
2115 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2117 * Made some sanity checks to silc_server_daemonise like to check
2118 whether the requested user and group actually exists.
2120 * Added sanity check to SKE's silc_ske_responder_finish to check
2121 that the public and private key actually is valid.
2123 * Invalidate the client's nickname when receiving Replace ID
2124 packet and the Client ID is being replaced. This means that the
2125 server will query the nickname if someone needs it (client)
2128 * Sort the ID Cache in client library when the ID Cache data
2129 has changed (needs sorting).
2131 * Do not allow for SILC client to create several connections to
2132 several servers. The client does not support windows right now
2133 and generating multiple connections causes weird behaviour.
2135 Irssi-silc client does support windows and can handle several
2136 connections without problems, see: www.irssi.org and SILC plugin.
2138 * Fixed some places where client was added to the IDList. The
2139 rule of thumb is following (in order to get everything right):
2140 If the client is directly connected local client then the
2141 `connection' argument must be set and `router' argument must be
2142 NULL to silc_idlist_add_client function. If the client is not
2143 directly connected client then the `router' argument must
2144 bet set and the `connection' argument must be NULL to the
2145 silc_idlist_add_client function.
2147 * The funtion silc_server_packet_send_local_channel actually did
2148 not check whether the client was locally connected or not. It
2149 does that now. Fixed a bug related to LEAVE command.
2151 * Fixed Remove Channel User payload parsing bug in server's
2152 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2154 * The server's silc_server_save_channel_key now checks also the
2155 global ID list for the channel as it might not be in the local
2156 list. Fixed a bug related to LEAVE command.
2158 * Is this the end of the [<unknown>] buglet that has been lurking
2159 around for a long time? A little for loop fix in server's
2160 silc_server_command_whois_parse that is used by both IDENTIFY
2161 and WHOIS command. At least, this was a clear bug and a cause
2162 of one type of [<unknown>] buglet.
2164 * WHOIS and IDENTIFY commands call the function
2165 silc_server_command_[whois/identify]_check function even if
2166 we are not router server.
2168 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2170 * Added --with-gmp configuration option. If set the GMP
2171 is always compiled in the SILC source tree. If not set then
2172 it is checked whether the system has the GMP3 installed. If
2173 it has then the GMP won't be compiled (the system's headers
2174 and library is used), if it doesn't have it then the GMP is
2175 compiled in the SILC source tree.
2177 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2179 * Changed RSA private exponent generation to what PKCS #1
2180 suggests. We try to find the smallest possible d by doing
2181 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2182 not security fix but optimization.
2184 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2186 * Added new config entry [Identity] to fork the server and run
2187 it as specific user and group. A patch from Bostik.
2189 * Imported Dotconf configuration library into lib/dotconf.
2190 This will be used to create the SILC configuration files later.
2191 It will appear in the distsribution after this commit.
2193 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2195 * A big code auditing weekend happening. Auditing code for
2196 obvious mistakes, bugs and errors. Also, removing any code
2199 Removed files for being obsolete:
2201 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2202 inline in the file lib/silcutil/silcbuffer.h)
2204 o lib/silcutil/silcbufutil.c (the header has inline versions)
2206 Changed code to fix possible error conditions:
2208 o The buffer formatting routines now check that the destination
2209 buffer really has enough space to add the data. This applies for
2210 both buffer formatting and unformatting
2211 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2212 unformatting was changed to accomodate following rules:
2213 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2214 sent to the function while XXX_*STRING will not allocate or copy
2215 the data into the buffer. Instead it sets the pointer from the
2216 buffer into the pointer sent as argument (XXX_*STRING used to
2217 require that the pointer must be allocated already). This change
2218 makes this whole thing a bit more consistent and more optimized
2219 (note that the data returned in the unformatting with XXX_*STRING
2220 must not be freed now). The routines return now -1 on error.
2222 o Tried to find all code that use buffer_format and buffer_unformat
2223 and added return value checking to prevent formatting and
2224 especially unformatting errors and possible subsequent fatal
2227 o Changed ske->x and ske->KEY to mallocated pointers in
2228 lib/silcske/silcske.h. Fixed possible data and memory leak.
2230 o Added return value checking to all *_parse* functions. Fixed
2231 many memory leaks as well.
2233 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2234 so that buffer overflows would not happen. All code now also
2235 checks the return value as it can fail.
2237 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Added reconnection support to server if the normal server looses
2240 its connection to the router (for example if router is rebooted).
2241 The server performs normal reconnection strategy implemented
2242 to the server. Affected file silcd/server.c.
2244 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2246 * Added new packet type SILC_PACKET_SET_MODE that is used to
2247 distribute the information about changed modes (for clients,
2248 channels and clients channel modes) to all routers in the
2249 network. Updated the protocol specification accordingly.
2251 Added functions into silcd/packet_send.c and
2252 silcd/packet_receive.c: silc_server_send_set_mode,
2253 silc_server_set_mode.
2255 Added new files silcmode.[ch] into lib/silccore that implements
2256 the encoding and decoding of Set Mode Payload. Added new type
2257 SilcSetModePayload. Moved the definitions of different modes
2258 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2260 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2262 * Oops, a little mistake in server's connection authentication
2263 protocol. The protocol is not ended with FAILURE but with
2264 SUCCESS if the authentication is Ok. :) Affected file is
2267 * Implemented NICK_CHANGE notify handling in server in the file
2268 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2269 the local clients on the channel. After the changing nickname
2270 in router environment snhould work and the [<unknown>] nickname
2271 should appear no more.
2273 The silc_server_replace_id function that receives the Replace ID
2274 payload now sends the NICK_CHANGE notify type also in the file
2275 silcd/packet_receive.c
2277 * Changed WHOIS and IDENTIFY command to support the maximum amount
2278 of arguments defined in protocol specs (3328 arguments). This
2279 fixed a bug that caused problems when there were more than three
2282 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2284 * Added extra parameter, command identifier, to the
2285 silc_client_send_command so that explicit command identifier
2288 Changed that ID list routines uses specific command identifier
2289 when sending WHOIS/IDENTIFY requests to the server so that they
2290 can be identified when the reply comes back.
2292 Affected files lib/silcclient/command.[ch],
2293 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2295 * Added `sender' argument to silc_server_packet_send_to_channel
2296 to indicaet the sender who originally sent the packet to us
2297 that we are now re-sending. Ignored if NULL. Affected file
2298 silcd/packet_send.[ch].
2300 * Added some server statistics support in silcd/server_internal.h
2301 SilcServerStatistics structure and around the server code. Also
2302 send some nice statistics information when client is connecting
2305 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2307 * Fixed channel ID decoding in server's JOIN command reply in
2308 silcd/command_reply.c
2310 * Fixed braodcasting of replace ID payload to not to send it if
2311 we are standalone server in silcd/packet_receive.c.
2313 * Fixed all channel message sending routines to not to send
2314 packets to clients that has router set, since they are routed
2315 separately in the same function earlier. Affects file
2316 silcd/packet_send.c and all channel packet sending functions.
2318 * In USERS reply, res_argv[i] are not allocated, the table
2319 is allocated. Thus changed that free the table, not its
2322 * In server's whois_check and identify_check if the client is
2323 locally connected do not send any WHOIS commands - they are not
2326 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2328 * Fixed some minor bugs in client when sending WHOIS command. The
2329 arguments was in wrong order.
2331 * Removed statis function add_to_channel from server in
2332 silcd/command.c that was previously used with the joining but
2335 * Tested USERS command in router environment successfully with two
2336 routers, two servers and two clients.
2338 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Reorganized the USERS command and command reply in client library
2341 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2342 When the command is given by user we register a pending command
2343 callback that will reprocess the command after the reply has been
2344 received from the server. When reprocessing the packet we then
2345 display the information. Thus, the USERS information is displayed
2346 now in the command callback instead of in the command reply
2347 callback. The processing of the command is same as previously
2348 when server has sent the command reply in the JOINing process.
2350 * Added to USERS command in silcd/command_reply.c to join the client,
2351 we didn't use to know about, to the channel after we've created
2352 a client entry for it. Also, for clienet we did know already still
2353 check whether it is on the channel or not and add it if not.
2355 * Removed silc_server_command_join_notify as the function and its
2358 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2360 * Changed the client's pending command handling to the same as the
2361 server's pending command handling. It is also now possible to
2362 execute command reply functions from other command reply
2363 function as the function callbacks for commands and command
2364 replies are one and same. The pending commands are not static
2365 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2366 in client connection context. Thus, pending commands are server
2367 connection specific as it is convenient.
2369 Changed the function silc_client_command_pending and
2370 silc_client_command_pending_del and added new function
2371 silc_client_command_pending_check. Removed the
2372 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2375 * Added cmd_ident, current command identifier, to the client
2376 connection context in lib/silcclient/client.h to keep track on
2377 command identifiers used in command sending. Client's command reply
2378 function handling now supports the mandatory command identifiers.
2380 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2381 funtions in client to fully support pending command callbacks.
2383 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2384 as one of the arguments to the application in the command reply
2387 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2388 before first releasing SILC but came back. Now it is removed again
2389 and should come back nomore. The FORWARDED flag was used only
2390 by the JOINing procedure by forwarding the command packet to router.
2391 Now, the JOINing procedure has been changed to more generic (due
2392 to various router environment issues) and FORWARDED is not needed
2393 anymore for anything. The protocol specification is yet to be
2396 Now, removed silc_server_packet_forward from server and the flag
2397 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2399 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2401 * Renamed NAMES command to USERS command. The NAMES was named that
2402 due to historical reasons. Now it is renamed. Also, rewrote
2403 parts of the USERS command. The nickname list is not sent anymore
2404 by the server. Only Client ID and mode lists are sent in the USERS
2405 command. Changed this also to the protocol specification.
2407 The client now resolves the names and stuff after it receives
2408 the USERS list from the server when joining to the channel.
2410 * WHOIS and IDENTIFY commands has been changed to support multiple
2411 Client ID's per command. One can now search for multiple users
2412 in the network by sending only one WHOIS or IDENTIFY command.
2413 Changed the code and the protocol specifications.
2415 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2416 uses silc_server_command_whois_parse to parse the request. */
2418 * If normal server, do not parse the WHOIS and IDENTIFY requests
2419 before sending it to the router. Saves some time.
2421 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2423 * Fixed JOIN command on client library. Wrong number of arguments
2424 used to crash the client.
2426 * Added silc_server_channel_has_global function to check whether
2427 channel has global users or not.
2429 * Added silc_server_channel_has_local function to check whether channel
2430 has locally connected clients on the channel.
2432 * The silc_server_remove_from_one_channel now checks whether the
2433 channel has global users or not after given client was removed from
2434 the channel. It also checks whether the channel has local clients
2435 on the channel anymore. If it does not have then the channel entry
2436 is removed as it is not needed anymore.
2438 * The silc_server_notify now checks on JOIN notify whether the joining
2439 client is one of locally connected or global. If it is global then
2440 the channel has now global users on the channel and that is marked
2441 to the channel entry. Also, it now saves the global client to
2442 global list who is joining and JOINs it to the channel. This is
2443 for normal server, that is.
2445 Changed silc_server_send_notify_on_channel,
2446 silc_server_packet_relay_to_channel and
2447 silc_server_packet_send_to_channel check if we are normal server
2448 and client has router set (ie. global client) do not send the
2449 message to that client, as it is already routed to our router.
2451 * Implemented LEAVE notify type handling in silc_server_notify
2454 * Tested LEAVE command in router environment successfully. Tested
2455 with two routers, two servers and two clients.
2459 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2461 * Implemented SIGNOFF notify type handling in silc_server_notify
2464 * silc_server_remove_id now removes the client entry from all channels
2465 it has joined and thusly sends SIGNOFF notify type.
2467 * Rewrote the NAMES list generation in server by removing two excess
2468 loops. The lists are created now inside one loop.
2470 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2472 * silc_server_remove_channel_user checks now also global list
2473 for channel and client.
2475 * silc_server_new_channel_user checks now both local and global
2476 list for channel and client. Fixed a bug in client id decoding.
2477 Used to decode wrong buffer.
2479 * silc_server_channel_message checks now both local and global
2480 list for channel entry.
2482 * Tested channel joining (hence JOIN) in router environment
2483 successfully. Tested with two routers, two servers and two
2486 * Tested channel message sending in router environment successfully.
2488 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Added silc_server_save_channel_key into server.[ch] to save the
2491 received channel key in Channel Key payload processing. It is
2492 also used in JOIN command reply handling.
2494 Equivalent function silc_client_save_channel_key added into
2495 client.[ch] into client library.
2497 * Changed JOIN command reply to send information whether the channel
2498 was created or not (is existing already) and the channel key
2499 payload. Changed protocol specs accordingly.
2501 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2502 the request was sent by ID and not by nickname. Crashed on
2505 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2507 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2508 now correctly save the received data.
2510 * silc_server_free_sock_user_data now notifies routers in the
2511 network about entities leaving the network.
2513 At the same time implemented functions silc_server_remove_id
2514 and silc_server_send_remove_id to receive and send REMOVE_ID
2515 packets. The packet is used to notify routers in the network
2516 about leaving entities. The ID removed will become invalid in
2519 * Added function silc_idlist_del_server into server. Removes and
2520 free's server entry from ID list.
2522 * silc_server_private_message function now checks, if we are router,
2523 that the destination ID really is valid ID, naturally.
2525 * In router when NEW_ID packet is received (for new client) the
2526 hash of the Client ID is saved in the ID Cache but the
2527 client->nickname is set to NULL, instead of putting the hash
2530 IDENTIFY command now also checks that client->nickname must be
2531 valid. If it is not if will request the data from the server who
2532 owns the client. Added new function
2533 silc_server_command_identify_check.
2535 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2536 to set the command to already allocated Command Payload.
2538 * Tested private message sending in router environment with two
2539 routers, two servers and two clients. Fixed minor bugs and now
2542 * Fixed segfault from client's NAMES command. Used to crash if
2545 * Forwarded packets must not be routed even if it is not destined
2546 to the receiver. Changed server code comply with this.
2548 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2550 * Added `require_reverse_mapping' boolean value to ServerParams
2551 structure. If TRUE (not default) the server will require that
2552 the connecting host has fully qualified domain name.
2554 If the reverse mapping is not required and hostname could not be
2555 found the IP address is used as hostname.
2557 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2559 * Implemented version string checking to both client and server.
2560 The check is incomplete currently due to the abnormal version
2561 strings used in development version of SILC.
2563 * Changed all command functions in server to use the new
2566 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2568 * Changed char *data to unsigned char *data in ID Cache system to
2569 support binary data as ID Cache data. Changed code to support
2570 binary data in lib/silccore/idcache.c.
2572 * Renamed silc_server_packet_relay_command_reply to
2573 silc_server_command_reply as it is normal packet receiving
2574 function. Rewrote the function to accept command replys for
2575 servers and not only for clients.
2577 * Mark remote router always as registered server if we are connecting
2578 to it. Otherwise, commands sent by the router to us are ignored.
2580 * All ID List find routines now returns the ID Cache Entry pointer
2581 as well if requested.
2583 * WHOIS command works now in router environment, tested with two
2584 routers, two servers and two clients.
2586 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2587 in router environment (as it is almost equivalent to WHOIS) but
2588 hasn't been tested thoroughly. Added new functions:
2590 silc_server_command_identify_parse
2591 silc_server_command_identify_send_reply
2592 silc_server_command_identify_from_client
2593 silc_server_command_identify_from_server
2595 * Disabled route cache adding because adding two different ID's with
2596 same IP replaces the old cache entry thus giving wrong route.
2597 The entry->router->connection is always the fastest route anyway
2598 so route cache may not be needed. Of course, new routes maybe
2599 established after receiving the ID when the entry->router->connection
2600 might not be anymore the most optimal.
2602 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2604 * Add route cache for received ID for fast routing.
2606 * Added silc_server_packet_route to route received packet on router
2607 that is not destined to us.
2609 * Renamed silc_server_get_route to silc_server_route_get.
2611 * Added id_string and id_string_len fields into SilcServer to
2612 include encoded ServerID for fast comparing without excess
2613 encoding of the ID's.
2615 * Cleaned up WHOIS command on server side. Added following static
2618 silc_server_command_whois_parse
2619 silc_server_command_whois_check
2620 silc_server_command_whois_send_reply
2621 silc_server_command_whois_from_client
2622 silc_server_command_whois_from_server
2624 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2625 arguments in command replies. All command functions should be
2626 updated to use this macro.
2628 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2630 * Minor typo fixes on command reply handling on server.
2632 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * Added silc_server_command_add_to_channel internal routine to add
2635 the client to the channel after router has created the channel and
2636 sent command reply to the server.
2638 * Added generic silc_server_send_command to send any command from
2641 * Use static buffer with ID rendering instead of duplicating data.
2643 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2645 * Fixed a channel user mode bug when joining to a channel server gave
2646 everybody channel founder rights, oops.
2648 * We mark ourselves as the router of the incoming server connection
2649 if we are router ourselves. This way we can check in some packet
2650 sending functions whether it is locally connected server. For
2651 incoming router connections we put NULL.
2653 * For router sending packets locally means now always sending the
2654 packet cell wide; to local clients and local servers. For normal
2655 server sending packet locally means sending it to only local
2658 * Fixed the JOIN command to really work in router environment. If the
2659 channel is created it is always created by the router. Router is
2660 also responsible of making the initial joining to the channel,
2661 sending JOIN notify to the sending server and distributing
2662 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2663 does not exist server doesn't do anything else but forward the
2664 command to the router which performs everything.
2666 * Added silc_server_send_channel_key function to send the Channel Key
2669 * Added silc_server_create_channel_key to create new channel key. The
2670 channel key is now re-generated everytime someone joins or leaves
2671 a channel, as protocol dictates. Note: channel->key_len is the
2674 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2676 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2677 packet_receive.[ch] to separate packet sending and receiving
2678 routines. The server.[ch] now includes everything else including
2679 actual packet processing (writing and reading data) and other
2682 Renamed silc_server_private_message_send_internal to
2683 silc_server_send_private_message. The routine is still though
2684 used only to relay private messages as server does not send
2685 private messages itself.
2687 Renamed silc_server_new_channel to silc_server_create_new_channel
2688 and added new function sicl_server_new_channel that handles the
2689 incoming New Channel packet. Added also new sending function
2690 silc_server_send_new_channel to send New Channel Payload.
2692 * Added new function silc_server_notify to process incoming notify
2693 packet to the server/router. Server may then relay the notify
2694 to clients if needed.
2696 * Added new function silc_server_new_channel_user to process incoming
2697 New Channel User packet. Router will redistribute the packet and
2698 send JOIN notify to its local clients and locally connected servers
2699 if needed. Normal server will send JOIN notify to its local client
2700 on same channel when received this packet. Added also corresponding
2701 sending function silc_server_send_new_channel_user to sent the
2704 * Added boolean route argument to send_notif_to_channel and
2705 packet_send_to_channel functions to attempt to route the packet
2706 if it is TRUE and send only locally if it is FALSE.
2708 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2710 * silc_server_replace_id now broadcasts the received replace ID
2711 packet if it is not broadcast packet already. The router must
2712 broadcast to inform other routers about changed ID.
2714 * Added backpointer to server's router into SilcServer context in
2715 silcd/server_internal.h.
2717 * Fixed silc_server_packet_broadcast to send correct broadcast
2720 * The channel key is now distributed to the local client as soon
2721 as it is received from the router (in router environment) so that
2722 no other packet may be sent for the channel until client has
2725 * silc_server_remove_channel_user now broadcasts the received
2726 Remove Channel User packet if it is not broadcast packet already.
2727 The router must broadcast to inform other routers about removed
2730 * Added users field into SilcPacketContext that is a reference count
2731 of the context. One can increase the reference count by calling
2732 silc_packet_context_dup which is now changed to just increase the
2733 reference count instead of duplicating the data. The reference
2734 count is decresed by calling silc_packet_context_free that will
2735 free the data after the reference count hits zero.
2737 For now on the packet context and everything allocated into it
2738 (including the raw packet from network) must be freed by calling
2739 the new silc_packet_context_free function. Added also new function
2740 silc_packet_context_alloc that must be used now to allocate the
2741 context. This also means that if a routine is asynchronous from
2742 silc_[client/server]_packet_parse_type the packet context must
2743 be duplicated by calling silc_packet_context_dup. Otherwise it
2744 gets free'd after silc_[client/server]_packet_parse_type returns.
2745 Also, one must remember that if packet is duplicated then its
2746 reference count must be decresed by calling the free function as
2747 many times as it was duplicated.
2749 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2750 from both client and server.
2752 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2754 * Made joining to a channel working in router environment.
2756 * Cleaned up JOIN command on server side and create function
2757 silc_server_command_join_channel internal routine to make the
2760 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2762 * Changed silc_command_pending list to SilcDList. Also, added
2763 `ident' field to SilcServerCommandPending structure to identify
2764 the reply and to call correct callback.
2766 Added silc_server_command_pending_check function to replace the
2767 corresnponding macro. The silc_command_pending list is not
2770 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2771 to set identifier to previously allocated Command Payload. It
2772 is used to set identifier for command when resending Command
2775 * Added silc_command_payload_encode_payload to encode Command
2776 Payload buffer from SilcCommandPayload structure.
2778 * Added silc_argument_payload_encode_payload to encode Argument
2779 payload buffer from SilcArgumentPayload structure.
2781 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2783 * Changed WHOIS command to support router connection on server side.
2784 The whois request is always sent to router unless the server is
2785 standalone server. After server has received the reply from the
2786 router will it send the reply to the client.
2788 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2789 broadcast received broadcast packet. The function is used only
2790 by router. The broadcast packet is always sent to the router's
2793 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2794 render given ID to printable string, for log files for example.
2796 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2798 * Made basic router to router connections working. At least they
2799 can now connect to each other but nothing really works the way
2800 they are supposed - yet.
2802 * Added new initiator token to RouterConnection configuration
2803 file in silcd/serverconfig.[ch]. It is used to tell whether we
2804 are the initiator to the remote router or whether we'll expect
2805 the other end to connect.
2807 * Moved registering of listener task to silc_server_init, hence
2808 the server starts listenning as soon as it is run, even if it
2809 does not have connections to other routers. Let's see how well
2812 * Changed default connection retry timeouts for more suitable in
2815 * Removed cipher and such arguments from silc_idlist_add_client
2816 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2817 Added new function silc_idlist_add_data to add the keys and stuff
2820 * Added SilcIDListData structure and added it to SilcClientEntry
2821 and SilcServerEntry as their first field in the structure. This
2822 way we can explicitly cast the ID entries to the SilcIDListData
2823 structure and get common data for the entries. In past, we had
2824 to first check what type of connection it is and then cast it to
2825 correct ID entry type. Now, we can directly cast the opaque
2826 pointer to the SilcIDListData (no matter what ID entry it actually
2827 is) and get the data needed.
2829 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2832 in some circumstances even if threre were timeout tasks, though not
2833 IO tasks, but tasks anyway. Now fixed.
2835 * Defined SilcServerConnection structure to hold connection specific
2836 stuff about directly connected servers and routers. The definition
2837 is currently in silcd/server_internal.h. I thought about having
2838 a bit more important role fro this struct but for now it is used
2839 only when connecting to other server (or router actually).
2841 * Added connecting retry support in server when connecting to
2842 router(s). The retry feature implement exponential backoff
2843 algorithm. Also, added SilcServerParams structure to hold default
2844 parameters for server. For now, it include these retry settings
2845 and are hard coded. After server is moded to be as Silc Server
2846 Library this structure will be more important.
2848 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Changed client librarys channel->clients table to SilcList and
2851 changed code accordingly.
2853 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Changed client's channel table to SilcList and changed code
2856 accordingly. Also changed SilcChannelClientEntry to include back-
2857 pointer to the channel so that client entry can use that structure
2858 as list as well and we have fast cross-reference to the channel.
2859 This change dramatically decreased the complexity of channel
2860 handling with client entry and vice versa (removed one extra
2861 loop when searching for channel entry from many functions).
2863 * Changed server->sim from table to SilcDList and changed code
2866 * NAMES command can now be used from user interface. It will show
2867 the user list on the channel, neatly.
2869 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2870 Code now saves realname of the user if it becomes available.
2872 * Renamed configure.in to configure.in.pre and made ./prepare
2873 script to automatically add correct version string to
2874 configure.in which it creates from configure.in.pre.
2876 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * NAMES command reply now shows users mode with the nickname when
2881 * Moved silc_client_ch[u]mode[_char] functions from
2882 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2883 place sucks, they are utility functions and should be in some
2886 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2888 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2891 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2895 * Added TRQ (efficient deque and list library) into lib/trq. This is
2896 a very good list library that is currently used in the SILC. Defined
2897 SilcList API over the library because I didn't like the API very
2898 much. See lib/trq/silclist.h for the API and examples of how to
2899 use the API. Fixed various places in the code to use the new
2900 SilcList API. The SilcList is meant for lists that has a structure
2901 already defined as a list. It is not suitable to add just some
2902 context to the list (in TRQ, the context is the list actually).
2904 So, I defined SilcDList that can be used for the purpose where
2905 predefined list structure does not exit. This can be used as
2906 such list. Now some context just can be added to the SilcDList.
2907 Currently this list is not used in the SILC just yet, though there
2908 are a lot places where this can replace dynamically allocated
2909 tables and I will fix these places, later, to use SilcDList.
2910 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2911 and use TRQ internally).
2913 Also fixed some annoying warning messages that the original TRQ
2914 code generated. Also minor changes to TRQ's Makefile.in.
2916 * Added support for querying by Client ID to both WHOIS and
2917 IDENTIFY commands into server, as required by the protocol.
2919 * Removed method function pointers from SilcBuffer structure. They
2920 weren't used to anything and just increased the context size for
2921 no good reason. This change also made silc_buffer_alloc and
2922 silc_buffer_free functions inline functions.
2924 * Disabled command flooding detection support until it's fixed so
2925 that it accepts commands in but does not execute them more than once
2928 * Added silc_net_localhost(), to return local hostname, into
2929 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2930 that must be initialized before calling silc_client_init.
2932 * Added new function: silc_server_send_notify_on_channels to send
2933 notify messages to all channels client has joined. It is assured
2934 that the message is sent only once per client.
2936 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2937 lib/silcutil/silcutil.[ch] as silc_format function. The new
2938 function is generic and is used by server as well, not only by
2939 the logging routines.
2941 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2942 the provided version string was not acceptable. Added new function:
2943 silc_ske_check_version into lib/silcske/silcske.h. The function
2944 must be implemented by the application (client or server) and it
2945 does not reside in the SKE library. The function checks the version
2946 string remote end sent.
2948 * Added back pointers (to opaque context and to SilcSocketConnection)
2949 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2951 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2952 duplicate packet context structure.
2954 * Changed `notify' client operation to send same arguments as client
2955 receives from server except for ID's. ID's are mapped to correct
2956 ID entry and that is returned. Also, if channel entry is not sent
2957 by server but the notify is for channel the channel entry is sent
2958 to application (otherwise application doesn't know that it is for
2959 channel (library gets it from packet's Destination ID)).
2961 * Added silc_client_remove_from_channels into client library to
2962 remove a client from all channels it has joined to. Used when
2963 received SIGNOFF notify from server. Added also new function
2964 silc_client_replace_from_channels to replace old ID entry with
2965 new ID entry on all channels. Used when received NICK_CHANGE
2968 * Fixed ID Cache list handling in silc_idlist_get_client in
2969 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2970 to get (or query) client by ID.
2972 * Updated TODO list.
2974 * Added connection authentication status message defined by the
2975 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2976 support for these into the code in client and server side.
2978 * Added generic function silc_client_send_command to send any command
2979 with variable argument list. Application should use this function
2980 to send commands if the command functions provided by the library
2981 does not suite for the application's user interface needs.
2983 * Added new `failure' client operation. Application is notified about
2984 received failure packet if client is executing a protocol. In this
2985 case the protocol's execution has failed.
2987 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2988 is required by the protocol.
2990 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2991 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2994 * Added status flag to SilcSKE object to indicate realtime status
2995 of the SKE protocol.
2997 * Application receives now exactly same command reply arguments as
2998 the library receives from server. However, if ID is received the
2999 corresponding ID entry is returned to the application (eg. Client
3000 ID is mapped to correct SilcClientEntry entry and that is returned).
3001 Changed command_reply client operation due to this change.
3003 * Changed all ID's in commands and in command replys as ID Payloads.
3004 Change affected both client and server side codes.
3006 All ID's sent in SILC network (with execption of ID's in SILC
3007 Packet header) are sent in ID Payload to support variable length
3010 * Server now notifies nick changes and notifies all clients on
3011 the channels about the new nickname (about the new Client ID,
3014 * Implemented CMODE command to change channel modes. Supports all
3015 channel modes defined by the protocol specs except ban and invite
3016 lists. (Also, private channel key mode is supported but support for
3017 setting private channel key in client is missing, thus, this mode
3018 has no effect on client side (except that server requires that the
3019 client uses private channel key and normal channel traffic does not
3022 Also, invite mode works per se, but INVITE command does not work
3023 yet correctly, so you can set channel as invite only channel but
3024 inviting clients to the channel does not work (it is yet to be
3025 thought what's the best way to do it).
3027 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3028 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3029 Implemented CUMODE command to change user's mode on the channel.
3030 Supports all modes defined by the protocol specs.
3032 * Added NAMES command reply to return users modes on the channel.
3034 * Removed unnecessary and slow ciphers from lib/silccrypt.
3036 * Set SO_KEEPALIVE option to connection sockets by default.
3038 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3040 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3041 redefined the Notify Payload into protocol specs.
3043 * Added silc_id_payload_parse_id to get ID directly from raw
3046 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3049 accept searching by Client ID as well.
3051 * Added support for LEAVE and SIGNOFF notify types in client library.
3053 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3054 to parse ID Payload from raw data.
3056 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3058 * Added flags parameter into silc_ske_assemble_security_properties
3059 function in lib/silcske/silcske.[ch].
3061 * Changed notify client operation to fit better for notify messages
3062 sent by server. The notify payload received from server is now
3063 passed to the application (after parsing it to SilcNotifyPayload).
3064 It is application's responsibility to retrieve the arguments
3065 from the payload and show the message the way it wants. The message
3066 sent by server is implementation specific.
3068 * Changed public keys to comply with the protocol specification.
3069 Old public keys are not supported anymore and are not compatible.
3071 * Removed nickname from Channel Payload as the latest draft removed
3072 it. The client must resolve the nickname from the NAMES command
3073 reply received when it joined the channel.
3075 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3077 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Fixed some errors in protocol specification drafts.
3081 * Created lib/silccore/silcnotify.c to implement Notify Payload
3082 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3083 generic payloads described by protocol specifications. The file
3084 includes implementations for ID Payload and Argument Payload.
3086 * Changed Command Payload implementation to use the new Argument
3087 Payload. Changed command_xxxx_payload to command_payload_xxxx
3088 to comply with SILC coding conventions.
3090 * Added suppport for Argument Payload handling in Notify Payload
3091 implementation as protocol requires it. Added the new support
3092 into server and client lib as well.
3094 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * Added support for multiple nicknames on same channel. [n] is
3097 added locally to the nickname if there are more than one same
3098 nicknames on the channel.
3100 * Server now sends all nicknames that matched WHOIS request.
3101 Client also shows the list received from server.
3103 * Added TOPIC command to client side. User can now set and show
3104 current topic on channel.
3106 * Added MOTD command to client and server. Also, server sends the
3107 motd when client connects to the server.
3109 * Changed version strings to comply ISO 8601.
3111 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Fixed protocol error handling in client library. It should now
3114 cope even if the SKE fails for some reason.
3116 * Made new protocol specification drafts for submitting to IETF.
3118 * Implemented TOPIC command to server in silcd/command.c.
3120 * Added two new notify types into lib/silccore/silcnotify.h:
3121 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3122 notify nickname change and topic setting/change on a channel.
3124 * API change of command_reply operation in client library. The
3125 application gets now the status type received from server as well.
3127 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3131 * Cras fixed and optimized the packet handling even further and
3132 it should work now. Minor change to the prototype of function
3133 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3135 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Added new function into lib/silcutil/silcschedule.[ch]:
3138 silc_schedule_with_fd to select() a specified fd. The function
3139 returns after timeout expires or data arrives or goes. The
3140 function is used by packet routines to wait that all data is
3141 received from network.
3143 * Fixed data reading from network in lib/silccore/silcpacket.c.
3144 The code now assures that all data is read from the fd and then
3145 continues packet processing. This was a bug fix since the code
3146 used to drop some data in some circumstances.
3148 * Added new function into lib/silcclient/client.[ch]:
3149 silc_client_start_key_exchange to start key exchange after
3150 connection has been established to server. The code internally
3151 now uses this funtion but its main purpose was to provide it
3152 for applications that perform their own connecting. After
3153 application has created a connection it merely calls this
3154 function to start the key exchange between client and server.
3155 The library takes care of everything else after that.
3157 Updated also lib/silcclient/README to explain the usage of
3160 * Do not send to application information that connection has
3161 been established. Application gets notified it by connect
3164 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Applied cras's patch to add silc_schedule_one function. The
3167 function runs scheduler once and returns.
3169 * Fixed the scheduler after cras messed it up. The timeout
3170 handling works now as it's supposed to work.
3172 * Added into lib/silccore/ silcnotify.h to include notify
3173 message types support. Changed silc_server_send_notify*
3174 functions, in server.[ch], to support those new notify types.
3175 Added the support for the notify types into client library,
3176 as well. Added new notify client operation into ops.h in
3179 * Changed silc_server_packet_send_to_channel to send normal
3180 packets instead of just channel message packets. The function
3181 is now used to send the notify packets to channels. It is not
3182 used to send channel message packets anymore, as server never
3185 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3186 va_arg()s as it seems to require it nowadays. I guess, if SILC
3187 is compiled with older va_arg() the new code should work anyway.
3189 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3191 * Splitted core library. Core library (lib/silccore) includes
3192 now only SILC protocol specific core (and common) components.
3193 Created new utility library (lib/silcutil) that includes more
3194 generic purpose stuff. The stuff for util library was taken
3195 from the old core library. This was minor and easy split.
3197 * Created SILC Client Library (lib/silcclient) that includes
3198 implementation of the SILC client without user interface. This
3199 was major move from silc/ directory. The code has been changed
3200 so that it is transparent towards the user interface. The
3201 silc/ directory includes now the same user interface as before
3202 and it uses the new client library. Read lib/silcclient/README.
3203 Basicly, the client library performs everything else related
3204 to SILC except user interface handling. Also, configuration
3205 files are considered to be part of user interface and library
3206 does not handle them.
3208 This change also changed a lot of structures, function naming etc.
3209 Most important change was that SilcClientWindow object was
3210 renamed to SilcClientConnection in the client library. Created
3211 also new file lib/silcclient/ops.h. Also added new files
3212 silc/local_command.[ch] and silc/client_ops.[ch].
3214 All these changes were made to make it easier for user interface
3215 designers to create what ever user interface for the SILC client
3218 It is also expected that the server will be moved to lib
3219 directory as well and SILC Server Library will be created;
3220 sometimes in the future.
3222 * Removed Local commands from lib/silccore/silccommand.h as
3223 they are application specific and new client library does not
3224 handle any of those anymore.
3226 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3227 old client implementation in silc/.
3229 * Added support for callback functions in SILC_LOG_* macros.
3230 Application can now set its own callbacks that will be called
3231 instead of using the default functions that will always print
3232 the debug messages to stderr (or stdout). Also, debugging can
3233 now be disabled by setting silc_debug to FALSE and re-enabled by
3234 setting it to TRUE. Note, that logging will still work even
3235 if debugging is disabled.
3237 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3238 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3239 silc_log_reset_debug_callbacks.
3241 * To enable debugging in silc client one must give now -d
3242 option on command line.
3244 * Changed silc_schedule_init to automatically allocate task queues
3245 if they are not allocated before calling it.
3247 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Added GMP 3.1 into math library.
3251 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3254 a channel in SILC network. The packet is used by servers and
3255 routers to notify other routers that user has left a channel.
3256 This little feature was missing until now. Added the feature
3257 to protocol specification as well.
3259 Added functions: silc_server_send_remove_channel_user and
3260 silc_server_remove_channel_user into server.[ch].
3262 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3263 lib/silccore/silcpacket.h. However, they are not implemented
3266 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Fixed joining to a channel and sending channel messages
3269 between server and router. The channel message sending should
3270 now work inside a cell.
3272 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3274 * Fixed the private message sending between server and router.
3275 The private message sending should now work inside a cell.
3277 * Added silc_server_replace_id into server.[ch] to replace
3278 existing ID in the SILC network.
3280 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3281 and silc_idlist_replace_server_id into idlist.[ch] in server.
3283 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Fixed the server to server connections. Server can again now
3286 connect to router. Router to router connections probably does
3289 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Added dynamic protocol registering support. Now protocols can
3292 registered and unregistered on the fly. Patch by cras.
3294 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3296 * Added lib/contrib directory to hold routines that some platforms
3297 don't have but are needed by SILC.
3299 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3300 into lin/contrib to provide getopt() and getopt_long() for
3301 those who don't have it.
3303 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3305 * Added AWAY command to client. When away message is set and
3306 client receives a private message packet the client automatically
3307 replies to the sender with the away message.
3309 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3310 bug seemed to be the cause of recent problems when compiling
3313 * Added version detection support to SKE protocol specification
3314 and added the new changes to the SKE implementation as well.
3315 There were other minor changes in the SKE protocol as well.
3317 Many changes in lib/silcske/silcske.[ch] and in
3318 lib/silcske/payload.[ch].
3320 * Added ^U functionality, clear input line. Patch from cras.
3322 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3324 * Mainly small bugfixes on core library. Fixed some debugging
3325 logging and buffer overflow in silclog.c.
3327 * Updated config.sub and config.guess on the distribution tree.
3329 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3331 * Added command lagging support in server. Client may execute
3332 commands now only once in two seconds.
3334 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Optimized packet reception. MAC computation and checking is now
3337 also more optimized. A lot previously duplicated code is now
3338 used as generic by both client and server.
3340 * Fixed key pair generation in clientutil.c
3342 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Added into lib/silccore/silcbufutil.[ch] new function;
3345 silc_buffer_realloc.
3347 * Moved generic packet sending/encryption functions to
3348 lib/silccore/silcpacket.[ch] from client and server. Some
3349 rewriting of the functions.
3351 * Moved all generic packet reception/decryption functions to
3352 lib/silccore/silcpacket.[ch] from client and server. The
3353 packet processing is now much cleaner in both client and server.
3354 These were major changes in both client and server.
3356 * Created many common functions in server to do packet sending.
3357 Previously code were duplicated a lot, this has been removed
3360 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Rewrote major parts of the ID cache system. Don't know
3363 whether it is better now or not but at least the API is more
3366 * Major rewrite on ID cache stuff on client because of the ID
3367 cache API changes. Added idlist.c to client.
3369 * Also major rewrite on ID cache stuff on server as well.
3370 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3371 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3372 in hand, instead they are all put into the ID cache system now.
3373 All server_idlist_* routines uses ID cache now instead of
3374 traversing its own lists (those lists does not exist anymore).
3375 SilcIDList though still exists. Also, SilcXXXEntry's are
3378 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Finally made the SKE implementation compliant to the protocol
3381 specification. All mp integers are now binary encoded as
3382 opposed being HEX encoded.
3384 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3387 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3388 functions: silc_[encode/decode]_pem. Also added function
3389 silc_encode_pem_file to PEM encode with newlines ('\n') for
3392 * SILC public keys are now encoded either PEM or binary. Same
3393 option is for private keys as well. By default private keys
3394 are binary encoded and public keys PEM encoded. Silly HEX
3395 encoding were removed.
3397 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3398 function to create fingerprints.
3400 * Fixed a bug in SHA1; does not change the original data anymore.
3402 * Partly implemented INFO command on client and server side.
3403 Fixed CLEAR command. Changes to SERVER command; show current
3404 server(s) when giving command without arguments. Added
3405 VERSION command to client.
3407 * Added check to server that unregistered connections cannot
3408 execute commands (unless it is specificly allowed).
3410 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * Fixed screen refresh.
3414 * Fixed channel joining bug from client. On some circumstances
3415 client tried to join to a channel it had already joined.
3417 * Added public key verification process into client's protocol.c.
3418 The client now verifies the public key from user and saves
3419 it into ~./silc/serverkeys/ directory.
3421 Added into: clientutil.[ch]: silc_client_verify_server_key.
3423 * Changed SKE protocol's silc_ske_initiator_finish function
3424 to accept callback function that verifies the received public
3425 key. Removed old silc_ske_verify_public_key function.
3427 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3430 silc_pkcs_private_key[_data]_set.
3432 * Made the password and public authentication more cleaner in
3433 server's protocol.c.
3435 * Removed historic and obsolete protocol `channel_auth' from
3436 both client and server.
3438 * Removed wrong way of sending command status messages from
3439 server to client in server's command.c. The old way violated
3440 protocol specification.
3442 Changes to silccore/silccommand.[ch]: removed
3443 silc_command_encode_status_payload -> not needed anymore,
3444 changed silc_command_encode_payload_va to accept extra
3445 argument on variable argument list. The argument type must
3446 now be provided to the function. Also, added new function:
3447 silc_command_encode_reply_payload_va which is same as
3448 normal command_encode_payload_va except command status type
3449 is provided as extra argument.
3451 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3453 * Added ~./silc directory handling. The directory includes the
3454 public and private keys for the client.
3456 Added silc_client_check_silc_dir, silc_client_create_identifier
3457 and silc_client_load_keys.
3459 * Implemented SILC protocol compliant public key. Added public
3460 and private key saving to and loading from files.
3462 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3463 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3464 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3465 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3466 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3468 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3469 silc_pkcs_load_[public/private]_key.
3471 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3473 * Added silc_server_get_route (route.[ch]) to get connection
3474 data for the fastest route for given ID.
3476 * Implemented INVITE command on client and server. The command
3477 were re-defined in the SILC Protocol Specification and the
3478 implementation now complies with the specification.
3480 * Implemented PING command on client and server.
3482 * Implemented NAMES command on client and server. The server side
3483 supports currently only normal server not router server yet.
3484 Some changes to NAMES definition in SILC protocol specification.
3486 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3488 * Implemented LEAVE command on client and server.
3490 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3491 again. This change was made to the protocol as well. Server
3492 should not violate the protocol specification anymore.
3494 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3497 was tested. SOCKS4 was not but should work anyway.
