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 Added new function silc_id_compare into lib/silccore/id.[ch].
9 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
10 both IPv4 and IPv6 based ID's.
12 The affected files are lib/silccore/id.[ch] and other files
13 around the tree using these routines.
15 * Removed the ID length arguments in server from various
16 silc_server_send_notify_* routines -> they are not needed
19 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
21 * Fixed memory leak in silc_encode_pem_file in the file
22 lib/silcutil/silcutil.c.
24 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
26 * Check minor version as well in the SKE. Affected files are
27 silcd/protocol.c and lib/silcclient/protocol.c.
29 * Added --identifier option to the server so that an identifier
30 can be when creating the public key for the server. Affected
31 file is silcd/silcd.c.
33 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
34 lib/silccrypt/silcpkcs.c.
36 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
38 * Register default ciphers and stuff when using -C option with
39 the server. Affected file sildc/silcd.c.
41 * Put back the servers public key filename format, it is better
42 than the new one. For now, the client keys are saved with the
43 new filename format. The affected file silc/client_ops.c.
45 * Implemented the Cipher API for the rest of the ciphers that
46 did not implement it or implemented it the wrong way.
48 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
50 * Register default ciphers and stuff when using the -S option
51 in the client. Affected file silc/silc.c. Same also when
52 creating new key pair with -C option.
54 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
56 * Fixed the silc_verify_public_key client operation function to
57 save the public keys differently. The fingerprint is now
58 used as filename and not the hostname. This way also the
59 client keys are saved uniquely and not with hostnames. The
60 affected file is silc/client_ops.c.
62 * Trimmed the silc_hash_fingerprint function to remove extra
63 whitespaces from the end of the fingerprint. The affected
64 file is lib/silccrypt/silchash.c.
68 * Added silc_cipher_register_default function to register all
69 default ciphers. It can be used when configuration files
70 does not exist and the application does not want any specific
71 ciphers in any specific order.
73 The SilcDList is now used as silc_cipher_list dynamically
74 allocated cipher list. Removed the static list all together
75 and now all ciphers must be allocated to the dynamic list.
76 The silc_cipher_alloc routine was changed to check only the
79 All silc_cipher_* routines that used to return int returns
82 The affected files lib/silccrypt/silccrypt.[ch].
84 * The same thing was done to silc_hash_* as for silc_cipher_*
85 routines. Affected files lib/silccrypt/silchash.[ch].
87 * The same thing was done to silc_pkcs_* as for silc_cipher_*
88 routines. Affected files lib/silccrypt/silcpkcs.[ch].
89 Added also silc_pkcs_[un]register[_default] functions.
90 Removed the data_context from the PKCS API.
92 * Added silc_hmac_register_default function to register default
93 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
94 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
95 to unregister all hmacs at once.
97 * Register the default ciphers, hash functions, PKCSs and HMACs
98 if client's configuration file does not exist. The affected
101 * The client did not load the hash functions from the SIM
102 modules at all. Added support for this. Affected file is
105 * When decoding public key with silc_pkcs_public_key_decode, check
106 the supported algorithm only if PKCS are registered. Affected
107 file lib/silccrypt/silcpkcs.c. The same was done with the
108 silc_pkcs_private_key_decode.
110 * Fixed the SILC List routines to keep the list always in order.
111 It used to change the list's order when traversing the list but
112 not it preserves the order. Affected file lib/trq/silclist.h.
114 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
116 * Added the client library to use the SilcSocketConnection's
117 reference counter (by silc_socket_dup) to prevent the bug that
118 the socket object may be freed underneath async operation.
120 * The name resolv library checking fixes in the configure.in.pre.
123 * Created new version of the protocol drafts for future
124 development. The -03 drafts are the ones that will be changed
125 in the trunk now and the -02 will remain as they are.
127 * Send list of CUMODE notifys to the router when announcing
128 the channel users to the router. Affected file silcd/server.c.
129 If the router receiving channel founder CUMODE for a channel
130 that already has channel founder it will send CUMODE notify
131 to the sender to remove the channel founder rights from the
132 announced client. Affected file silcd/packet_receive.c.
134 * The CUMODE notify may now use Server ID as well as the entity
135 who changes the mode. Updated protocool specs.
137 * Updated INSTALL and README files.
139 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * New web pages in the http://silc.pspt.fi. The pages was
146 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Implemented the [DenyConnectin] config section in the server.
149 Added silc_server_config_denied_conn to check whether incoming
150 connection is denied. Affected file silcd/serverconfig.[ch].
152 * Do not check the ports when checking the incoming configuration
153 data if the port is 0, meaning any. Affected file is
154 silcd/serverconfig.c.
156 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
158 * Fixed buffer overflow in silc_string_compare in the file
159 lib/silcutil/silcutil.c.
161 * Fixed double free in silc_server_command_leave in the file
164 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
166 * Fixed the version checking in the server. Affected file is
169 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
171 * Fixed the configuration data fetching when accepting new
172 connections in the server. Affected file silcd/server.c.
174 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
176 * Added `sender_entry' argument to the function
177 silc_server_packet_relay_to_channel so that we can check
178 whether some destination actually belongs to the same route
179 the sender belongs (ie, we must not resend the packet to the
180 sender). Affected file silcd/packet_send.[ch].
182 * Added `servername' field to the SilcClientEntry in the server
183 to hold the name of the server where client is from. Affected
184 file is silcd/idlist.h.
186 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
188 * Moved the channel message encrypting in the router betwen
189 router connections from silc_server_channel_message to the
190 silc_server_packet_relay_to_channel since we want to check
191 whether we have anybody channel before encrypting anything.
192 Affected files silcd/packet_[receive/send].c.
194 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
196 * Fixed the [AdminConnection] server config section to support
197 multiple entries. Affected file silcd/serverconfig.c.
199 * Added support into the server to check the validity of the
200 incoming connection before executing any KE or authentication
203 * The connection configuration is now saved to the KE and
204 connection auth protocol contexts and not fetched anymore in
205 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
207 * The local hosts listenning address and port is also resolved
208 now when starting the server. We want to have the socket object
209 to include the real address and port for the listener. Added
210 new function silc_net_check_local_by_sock into the files
211 lib/silcutil/silcnet.[ch].
213 * Fixed a broadcast bug in server -> do not broadcast if we
216 * Fixed a routing bug. Do not route broadcast packets ever.
217 Broadcast packets must be processed always and not routed since
218 they may be destined to some other host than yourself and thus
219 would get routed without no good reason. Affected file is
222 * Added function silc_server_config_is_primary_route to check
223 whether primary router connection has been configured (a router
224 configuration that we are initiating). If there is not, we
225 will assume that there is only two routers in the SILC network
226 and we will use the incoming router connection as our primary
227 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
229 * Changed the order of the broadcasting. Broadcast _after_ the
230 packet has been processed not before. Affected file is
233 * Fixed a [ClientConnection] parsing bug. The port was never
234 parsed correctly thus resulting to port 0. Affected file
235 silcd/serverconfig.c.
237 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
238 argument and did not set the broadcast packet flag. Affected
239 file silcd/packet_send.c. Fixed same bug in the function
240 silc_server_send_notify as well.
242 * If we receive NEW_ID packet for our own ID in the server, ignore
245 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
249 * Removed the nickname from the Private Message Payload.
250 Updated the code and the protocol specs.
252 * Updated protocol specs for submitting to the IETF.
254 * Tweaked the Random Number Generator a bit. Affected file
255 lib/silccrypt/silcrng.c. Exported a new function
256 silc_rng_[global]_add_noise which can be used to add more
259 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
261 * Do not parse packets with different timeout when protocol
262 is active -> may cause problem with rekey. Affected file
265 * When server receives signoff notify it must not create
266 new channel key if the client is on any channels since the
267 sender of the signoff notify will create it.
269 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
271 * Added printing of error messages during SKE protocol from the
272 failure packet sent by server during SKE. Affected file
275 * Removed the client's failure_callback handling with timeout
276 and handle it immediately when received.
278 * The SKE library returned wrong type in SUCCESS and FAILURE
279 packets. They must be 32 bit MSB not 16 bit MSB.
281 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
283 * Ok, rewrote the logic of the re-key and now it seems to work.
284 I tested it on high traffic with frequent re-keys without
285 problems. Added hmac_receive (and renamed hmac to hmac_send)
286 in SilcClientConnection in lib/silcclient/client.h and
287 in SilcIDListData in silcd/idlist.h. Also, removed the
288 SilcPacketParserContext's cipher and hmac fields as they are
289 not needed anymore and actually caused some problems when
290 the ciphers and hmac's changed underneath the packet parser.
292 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
294 * If re-key protocol is active then process the incoming packets
295 synchronously since we must assure that icoming packets encrypted
296 with the old key is processed before the new keys is set to
297 use. This is true other packets than for REKEY packets.
298 Affected file silcd/server.c. The same was done to client library
299 as well, affected file lib/silcclient/client.c.
301 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
303 * Fixed bug in client and server to accept the force send if
304 the packet is send from silc_[server/client]_packet_process
305 function. Otherwise the packets are never delivered, oops.
307 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
309 * Disable force sending of packets when REKEY protocol is active.
310 We must assure that no packet is sent directly when rekey is
311 performed. All packets must be sent through packet queue.
312 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
313 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
314 function is silc_[server/client]_packet_send_real to check
317 * Replaced the SIM paths from example config files to
318 /usr/local/modules. Also, make install creates now
319 /usr/local/silc/logs directory to hold all the SILC server
322 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
324 * Made the configure.in.pre work on Solaris. Patch by salo.
326 * Made all ciphers compatible with non-x86 machines. Defined
327 CBC mode macros into lib/silccrypt/ciphers_def.h.
329 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
331 * Fixed the make install.
333 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
335 * When MAC computation fails the silc_packet_decrypt returned 0
336 even though it was supposed to return -1. Fixed this. The
337 affected file is lib/silccore/silcpacket.c.
339 * Do not replace the config files in /etc/silc (in make install)
340 if they already exist. Affected file ./Makefile.am.
342 * Do not send re-key packets immediately but through packet queue.
343 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
345 * Changed silc_net_check_host_by_sock to return FALSE if the
346 IP/DNS could not be resolved. Though, it returns the IP address
347 now even if it could not resolve it (but returns also FALSE).
348 Affected file lib/silcutil/silcnet.[ch].
350 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
352 * Added silc_pkcs_decode_identifier to decode the public key's
353 identifier. Affected file lib/silccrypt/silpkcs.[ch].
354 Added also silc_pkcs_free_identifier. Added also new context
355 SilcPublicKeyIdentifier.
357 * Added -S option to the silc client. It is used to dump the
358 contents of the specified public key file.
360 * Changed the PKCS api to return the public key length when
361 setting the public key.
363 * Fixed a fatal bug in the public and private key file loading.
364 Affected file lib/silccrypt/silcpkcs.c.
366 * Execute the packet parsing for client with zero (0) timeout
367 if the protocol is active. Affected file silcd/server.c.
369 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
371 * Made the key generation options to the silcd program. Added
372 -C option, equivalent to client's option.
374 * Added new [ServerKeys] config section to the server. It
375 configures the server's public and private key.
377 * Defined generic Public Key Payload into the protocol
378 specification to send specific type of public keys and
381 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
382 public key or certificate.
384 * Implemented the GETKEY command to the server and to the
385 client library and on user interface.
387 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
389 * Made preliminary `make install' work.
391 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
393 * Added SilcServerRekey context into silcd/idlist.h.
395 * Added the PFS support as defined in the specification to the
396 SKE protocol. Affected files lib/silcske/*.c.
398 * Added `ske_group' field to the SilcServerRekey context to hold
399 the number of the SKE group that is used with PFS in re-key.
400 Affected file silcd/idlist.h.
402 * Added PFS re-key support to the server. Affected file is
405 * Added silc_protocol_cancel to cancel execution of the next
406 state of the protocol. Affected file is
407 lib/silccore/silcprotocol.[ch].
409 * Added the re-key support with and without PFS to the client
410 library. Re-key is performed once in an hour, by default.
412 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
413 Added silc_client_rekey_callback and silc_client_rekey_final.
414 Affected files are lib/silcclient/protocol.[ch] and
415 lib/silcclient/client.[ch].
417 * Removed the `hmac_key' and `hmac_key_len' fields from the
418 SilcClientConnection structure; not needed. Affected file is
419 lib/silcclient/client.h.
423 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
425 * Do not ask whether user wants to use the negotiated private key
426 for private messages, just use it. Affected file is
427 silc/local_command.c.
429 * Added `send_enc_key' and `enc_key_len' fields to the
430 SilcIDListData structure since they are needed in the re-key
431 phase. Affected file is silcd/idlist.[ch].
433 * Implemented the simple re-key protocol into the server.
434 Affected files silcd/server.c and silcd/protocol.[ch]. The
435 re-key will be performed once in an hour, by default.
437 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
438 Added silc_server_rekey, silc_server_rekey_callback and
439 silc_server_rekey_final.
441 * Removed Tunneled flag from the protocol. Updated the code
442 and the specifications.
444 * Adde `pfs' field to the SilcIDListData to indicate whether
445 the PFS is to be performed in the re-key. Affected file is
448 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
451 int64 of at least the xintXX size. If void * is less that 4
452 bytes uint32 * will be used. Defined bool as boolean.
454 * Changed _ALL_ unsigned long and unsigned int to uint32,
455 unsgined short to uint16 in the source tree.
457 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
458 not handle clients that has entry->data.registered == FALSE.
459 They are not in the network anymore. Affected file is
462 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
464 * Implemented the sending of the SERVER_SIGNOFF notify in the
465 server. Affected file is silcd/server.c.
467 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
468 Added also silc_notify_payload_encode_args into the
469 lib/silccore/silcnotify.[ch].
471 * Implemented ther SERVER_SIGNOFF notify handling in the server.
472 Affected file silcd/packet_receive.c.
474 * Implemented the SERVER_SIGNOFF notify handling in the client
475 library. Affected file lib/silcclient/client_notify.c. Also,
476 implemnted the printing of the SERVER_SIGNOFF info to the
477 application. Affected file silc/client_ops.c.
479 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
480 if the deleting was successful. Affected file silcd/idlist.[ch].
482 * Added support for public key authentication in the connection
483 authentication protocol in the client library. Affected file
484 lib/silcclient/protocol.c.
486 * Changed the server's silc_idlist_get_clients_by_* interface
487 to support already allocated array so that new entries may be
488 added to pre-allocated array. Affected file silcd/idlist.[ch].
489 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
492 * All command reply functions in the server now calls the
493 pending command callback even if error occured. This way the
494 error will be delivered to the client as well. Affected files
495 silcd/command.c and silcd/command_reply.c.
497 * Fixed INFO command to return local server's info if no server
498 was provided. Affected file lib/silcclient/command.c.
500 * Removed RESTART command for good. Updated the code and the
503 * Rewrote parts of the task system. It is a bit simpler now.
504 Removed unsued task priorities. The affected files are
505 lib/silcutil/silctask.[ch].
507 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
509 * Moved the USERS printing from the library to the application.
510 Affected files lib/silcclient/command.c and silc/client_ops.c.
512 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
516 * Added channel key re-key support. The re-key is perfomed
517 only by the router and is done once in an hour. Added `rekey'
518 field to the SilcChannelEntry in the server. Affected files
519 silcd/server.c and silcd/idlist.h.
521 * Added silc_task_unregister_by_context into the file
522 lib/silcutil/silctask.[ch].
524 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
526 * Added SILC_UMODE_GONE mode to indicate when the client is not
527 present in the SILC network. Added also support to the local
528 command AWAY that will set this mode. Added support of showing
529 "xxx is gone" in WHOIS command. The USERS command shows the
532 * Fixed setting server and router operator privileges in the
533 server's UMODE command. Affected file silcd/command.c.
535 * Merged the SKE KE1 and KE2 payloads into one payload. The
536 new KE payload is equivalent to the old KE2 payload.
538 Cleaned up the SKE Start Payload parsing. It now uses the
539 simple buffer unformatting to do the parsing. A lot faster
542 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
543 to the SKE that is used to indicate whether both of the SKE
544 parties should perform authentication. By default only the
545 responder performs authentication. By setting this flag also
546 the initiator must do authentication. By default it is unset
547 since in normal SKE case, client to server connection, only
548 the responder should do authentication. When doing SKE between
549 two clients both should perform authentication. Updated the
550 code and the protocol specs.
552 * A little fix to IDENTIFY command in the server. Search the
553 client first by hash not nickname. Affected file is
556 * Fixed the silc_client_close_connection to support closing
557 the client to client connections wihtout deleting too much
558 data. Affected file lib/silcclient/client.c.
560 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
561 are received if protocol used to be active but is not anymore
562 the application would crash due to NULL pointer dereference.
563 Affected files silcd/server.c and lib/silcclient/client.c.
565 * Added `hash' field to the SilcClientConnection to include
566 the hash function negotiated in the SKE protocol.
568 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
569 to set the channel founder authentication data. A client can
570 claim the founder rights later by providing the authentication
571 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
572 This way the channel founder can regain the channel founder
573 privileges even it is left the channel. This works only on
574 local server and the client must be connected to the same
575 server to be able to regain the founder rights. Updated the
576 protocol specs accordingly.
578 Added support to the CMODE command in the client to set the
579 founder auth data. Read the README to see how to set it.
581 Added support to the CUMODE command to claim the founder
582 rights. Read the README to see how to do it.
584 Added support for the founder authentication to the Channel
585 Entry in the server. Affected file silcd/idlist.h.
587 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
588 server's CMODE command. Affected file silcd/command.c.
590 * Added the following new functions into lib/silccore/silcauth.[ch]:
591 silc_auth_get_method and silc_auth_get_data.
593 * The server now saves the remote hosts public key to the
594 SilcIDListData pointer. Affected file silcd/protocol.c.
596 * The normal server now does not remove the channel entry from
597 the cache if the founder authentication data is set. It used
598 to remove it if the founder was the last one on the channel on
599 the server and left the channel. The auth data is saved and
600 if the channel is re-joined later the old entry is used with
601 the old auth data. Affected files silcd/command_reply.c and
604 * Removed the `pkcs' field from the SilcIDListData structure
605 in the server; it is not used. Affected file silcd/idlist.h.
607 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
609 * Fixed packet processing on slow links. Partial packets were
610 never re-processed because the incoming data buffer was cleared
611 by the application. Application must not directly clear the
612 sock->inbuf, the packet processing routines handle it. Fixed
613 this in client library and in server.
615 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
617 * Fixed the WHOIS and IDENTIFY send reply function to really
618 check whether to send list or just one entry. Affected file
621 * Cleaned up the LEAVE command's channel key distribution. The
622 affected file silcd/command.c.
624 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
625 can enforce the channel mode as well. In that case the ID
626 includes the ID of the server. The code now enforces the
627 mode change if the router have different mode than the server.
629 * The notify client operation with CMODE_CHANGE notify can now
630 return NULL client_entry pointer if the CMODE was not changed
631 by client. Application must check for this.
633 * Added <Server ID> argument to INFO command to support server
634 info fetching by Server ID.
636 * Added silc_server_announce_get_channel_users to get assembled
637 packets of channel users of the specified channel. Affected
638 file silcd/server.[ch].
640 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
641 was freed underneath the ID Cache.
643 * Re-announce clients when the server received CHANNEL_CHANGE
644 notify from the router. Affected file silcd/packet_send.c.
646 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
648 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
649 crashed since it did not handle the fact that there is no cipher
650 called "3" and didn't check the error condition. Now fixed.
652 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
653 flag. It can be used to send message requests.
655 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
657 * Implemented the RESTART command in the client.
659 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
660 notice type messages. Added notice printing to the user
663 * The channel keys are not re-generated if the channel's mode
664 is PRIVKEY, ie private key on the channel exists. Affected
665 files silcd/server.c and silcd/command.c.
667 * Fixed a little bug in channel message delivery when channel
668 private keys are set in the server. Affected file is
671 * Changed the setting on channel->on_channel = TRUE from the
672 silc_client_save_channel_key to the JOIN command reply. The
673 key payload is not received if the private channel key is set.
674 Affected file lib/silcclient/command_reply.c and the
675 lib/silcclient/client_channel.c.
677 * When the CMODE_CHANGE notify is sent and the channel private
678 key mode is removed the channel key must be re-generated in
679 other cells as well. Added this support for the router in the
680 silcd/packet_receive.c.
682 * Added new local command NOTICE to send notice message on
683 channel. Affected file silc/local_command.[ch].
685 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
687 * Added new local command ME to the client. It is used to send
688 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
689 some action. Affected file silc/local_command.[ch].
691 * Changed channel_message and private_message client operations
692 to deliver the message flags to the application. Added also
693 the `flags' arguments to the silc_client_send_channel_message
694 and silc_client_send_private_message functions. Affected file
697 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
699 * Redefined the Private Message Payload to support private message
700 keys and to support the new private message flags. Updated
701 the protocol specs. Flags makes it possible to have for example
704 * Added new type SilcPrivateMessagePayload and defined an API
705 for it in the lib/silcclient/silcprivate.[ch].
707 * Tested private message private keys successfully. Tested the
708 private message key set, unset and list commands with the new
711 * Redefined the Channel Message Payload to include the channel
712 message flags (equal with private message flags) to support
713 for example CTCP style messages.
715 * Defined some of the message (for channel and private message)
716 flags. Updated the protocol specs and added the flags to the
717 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
719 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
721 * Added SilcKeyAgreementStatus type to the key agreement routines
722 to indicate the current status and error if one occured.
723 The status types are defined in the lib/silcclient/silcapi.h.
725 * Added new local command KEY that is used to set and unset private
726 keys for channels, set and unset private keys for private messages
727 with remote clients and to send key agreement requests and
728 negotiate the key agreement protocol with remote client. The
729 key agreement is supported only to negotiate private message keys,
730 it currently cannot be used to negotiate private keys for channels,
731 as it is not convenient for that purpose.
733 * Fixed a minor pending callback setting bug in the function
734 silc_client_get_client_by_id_resolve, now the function works.
735 Affected file lib/silcclient/idlist.c.
737 * Added function silc_net_get_local_port to get local bound
738 port by socket. Added to lib/silcutil/silcnet.[ch].
740 * Added `sockets' and `sockets_count' fields to the SilcClient
741 object. They hold the sockets of the listenning sockets in
742 the client. Listenning sockets may be for example the key
743 agreement server. Affected file lib/silcclient/client.[ch].
744 Added functions the silc_client_add_socket and the
745 silc_client_del_socket. They are exported to the application
748 * Added ~./silc/clientkeys to support other client's public keys.
750 * Renamed verify_server_key client operation to verify_public_key
751 and added one argument to indicate the type of the connection
752 (server, client etc.).
754 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
756 * Added silc_server_connection_auth_request to handle the
757 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
758 silcd/packet_receive.[ch].
760 * Added silc_server_send_connection_auth_request into the
761 silcd/packet_send.c to send the connection auth request packet.
763 * Cleaned up the silcd/protocol.c a bit and fixed some memory
766 * Fixed the public key authentication in responder side in the
767 server. The `auth_data' pointer includes the SilcPublicKey
768 not the path to the public key. Affected file silcd/protocol.c.
770 * Implemented the public key authentication in the initiator side
771 in the server. Affected file silcd/protocol.c.
773 * Removed the [RedirectClient] config section from the server
774 configuration. Is not needed and I don't want to implement it.
776 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
778 * Cleaned up the CMODE command in the server. It now works
779 correctly and supports all the modes defined in the protocol.
780 Affected file is silcd/command.c.
782 * Added `hmac_name' field to the SilcChannelEntry in the server
783 to hold the default HMAC of the channel. It can be set when
784 creating the channel (with JOIN command). Affected files
787 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
788 type to indicate the change of the current cipher and hmac
789 on the channel. Client can safely ignore the <cipher> argument
790 (if it chooses to do so) since the CHANNEL_KEY packet will
791 force the channel key change anyway. The <hmac> argument is
792 important since the client is responsible of setting the new
793 HMAC and the hmac key into use.
795 * Fixed the CMODE command in the client library as well.
797 * Tested CMODE command in router environment successfully.
799 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * Show the version of the remote client (or server) when connecting
802 to the server. It is logged to the log file. Affected file
805 * Fixed the KILLED notify handling in the client library. The
806 client must be removed from all channels when receiving the
809 Also, do not remove the client entry when giving the KILL
810 command but when the KILLED notify is received.
812 * Removed silc_idlist_find_client_by_nickname from the server.
813 Not needed anymore. Affected files silcd/idlist.[ch].
815 * Implemented the CHANNEL_CHANGE notify type handling to the
816 server. Affected file silcd/server.c.
820 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
822 * Added silc_server_send_notify_invite to send the INVITE
823 notify between routers.
825 * Implemented the INVITE command correctly to the server.
827 * Implemented the INVITE notify type handling in the server.
829 * Implemented the INVITE command to the client library and on the
832 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
834 * Added function silc_server_get_client_resolve to find the
835 client entry by ID from all ID lists and then resolve it
836 (using WHOIS) if it cannot be found. Affected file is
839 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
841 * Implemented the BAN command to the client library.
843 * The JOIN command in the server now checks the invite list
846 * Changed the silc_command_reply_payload_encode_va and the
847 silc_command_payload_encode_va to support that if argument is
848 NULL it ignores and checks the next argument. Affected file
849 lib/silccore/silccommand.c.
851 * Added silc_server_send_notify_ban to send the BAN notify
852 type between routers.
854 * Chaned the silc_notify_payload_encode to support that if
855 argument is NULL it ignores and checks the next argument.
856 Affected file lib/silccore/silcnotify.c.
858 * Tested ban lists in router environment successfully.
860 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
862 * Implemented BAN command to the server, in silcd/command.[ch].
864 * Removed the BAN and INVITE_LIST modes from the CMODE command
867 * Added function silc_string_match to regex match two strings.
868 Affected files lib/silcutil/silcutil.[ch].
870 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
872 * Redefined parts of the SilcChannelEntry in the server to support
873 the new ban and invite lists.
875 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
877 * Redefined the INVITE command. The same command can be used to
878 invite individuals to the channel but also to manage the invite
879 list of the channel (to add to and remove from the invite list).
880 Updated the protocol specs.
882 * Added new command SILC_COMMAND_BAN that can be used to manage
883 the ban list of the channel. Updated the protocol specs.
885 * Removed the channel modes: the SILC_CMODE_BAN and the
886 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
887 in the CMODE command. The equivalent features are now available
888 using INVITE and BAN commands. Updated the protocol specs.
890 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
891 in the network about change in the current ban list. The notify
892 type is not used by the client.
894 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
895 support the invite lists.
897 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
899 * Added new function silc_string_regexify that converts string
900 including wildcard characters into regex string that can
901 be used by the GNU regex library. Added into the file
902 lib/silcutil/silcutil.[ch].
904 Added silc_string_regex_combine to combine to regex strings
905 into one so that they can be used as one regex string by
906 the GNU regex library. Added into the file
907 lib/silcutil/silcutil.[ch].
909 Added silc_string_regex_match to match two strings. It returns
910 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
912 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Imported GNU regex to the soruce tree into lib/contrib.
915 Fixed some compiler warning from the regex.c.
917 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
919 * Fixed MOTD command in the server to work in router environment.
921 * Fixed the MOTD command in the client library to support
922 the server argument in the command.
924 * Added `nickname_len' argument to the silc_idlist_add_client
925 in the server, as the `nickname' argument may be binary data
928 * Added silc_idlist_get_channels to return all channels from
931 * Implemented LIST command to the server. Affected file is
934 * Implemented the LIST command to the client library and on the
937 * Added [<user count>] argument to the LIST command reply.
938 With private channels the user count is not shown.
940 * Updated TODO and README.
942 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
944 * The client entry's data.registered must be TRUE even with
945 global client entry on global client list. The data.registered
946 is used to check whether the client is anymore in the network,
947 for example with WHOWAS command so it must be valid.
949 * Fixed the WHOWAS command in the server. It now actually works
950 in router environment. Added function into silcd/command_reply.c
951 silc_server_command_reply_whowas_save.
953 * Added silc_idlist_purge function to the silcd/idlist.c
954 to periodically purge the ID Cache.
956 * Fixed INFO command in the server. It works now in router
957 environment. Added <server name> argument to the INFO command
958 reply. Updated the protocol specs.
960 * Fixed minor bug in silc_idcache_purge to not purge if the
961 expire value is zero.
963 * Fixed various bugs in WHOIS and IDENTIFY command handling as
964 they were buggy because of the WHOWAS information.
966 * Fixed local command MSG to handle the async resolving of
967 the remote client properly. It used to fail the first MSG.
968 Affected file silc/local_command.c.
970 * Added `data_len' field to SilcIDCache context.
972 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
974 * Update TODO. Todo in commands in the server.
976 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
978 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
979 used by routers as broadcast packet to inform other routers
980 about the changed user mode.
982 Implemented the notify handling in the server. Affected file is
983 silcd/packet_receive.c. Added the function
984 silc_server_send_notify_umode to the silcd/packet_send.[ch].
986 * Added new generic Channel Payload and deprecated the New Channel
987 Payload. The New Channel Payload is now the generic Channel
990 * Added new argument `mode' to the silc_server_send_new_channel
991 as it is required in the Channel Payload now.
993 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
994 and created a new and real SilChannelPayload to represent the
995 new generic Channel Payload. Implemented the encode/decode
996 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
998 * Added silc_server_get_client_channel_list to return the list
999 of channels the client has joined for WHOIS command reply.
1000 Affected file silcd/server.[ch].
1002 * Implemented the channel list sending in the WHOIS command reply
1003 in server and in the client.
1005 Implemented the channel list displaying on the user interface
1006 as well. Affected file silc/client_ops.c.
1008 * Added silc_channel_payload_parse_list to parse list of Channel
1009 Payloads. It returns SilcDList list of SilcChannelPayloads.
1010 Client for example can use this function to parse the list of
1011 channels it receives in the WHOIS command reply. The caller
1012 must free the list by calling silc_channel_payload_list_free.
1013 Affected files lib/silccore/silcchannel.[ch].
1015 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1017 * Added one new argument <user mode> to the WHOIS command reply
1018 to return the mode of the user in SILC. Updated the protocol
1021 Implemented it to the server and client.
1023 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1025 * Fixed the mode printing on the user interface on joining.
1026 Affected file silc/client_ops.c.
1028 * Implemented the UMODE command and user modes in general to the
1029 client library and to the user interface.
1031 * Implemented the UMODE command to the server.
1033 * The server now sends UNKNOWN_COMMAND error status if client sends
1034 unknown command. Affected file silcd/command.c.
1036 * All server commands now handle the command identifier the right
1037 way when sending the command reply to the client. The client can
1038 use to identify the command replies with the identifier.
1040 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1042 * Added silc_server_get_client_route to resolve the route to
1043 the client indicated by the client ID. Affected file is
1046 * Added silc_server_relay_packet as general function to relay
1047 packet to arbitrary destination. This deprecates functions
1048 like _send_private_message_key, _relay_notify etc. Affected
1049 file is silcd/packet_send.[ch].
1051 Removed silc_server_send_key_agreement,
1052 silc_server_send_private_message_key and
1053 silc_server_packet_relay_notify functions from the file
1054 silcd/packet_send.[ch].
1058 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1059 server. Affected file silcd/packet_receive.[ch].
1061 * Implemented the KILL command to the client. Implemented the
1062 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1063 Affected files lib/silcclient/command[_reply].c and
1064 lib/silcclient/client_notify.c. Implemented the KILL notify
1065 printing in the user inteface.
1067 * Fixed a lot silc_parse_nick memory leaks from the client
1068 library in the file lib/silcclient/command.c.
1070 * Changed the silc_server_send_notify_on_channels's `sender'
1071 argument from SilcSocketConnection to SilcClientEntry to
1072 check the sender as entry and not as connection object and not
1073 to send to the client provided as argument. The affected file
1074 is silcd/packet_send.[ch].
1076 * The notify packets that are destined directly to the client used
1077 to not to be processed by the server. Now changed that and the
1078 server processes all notify packets. After relaying the packet
1079 to the client the notify packet is processed in the server.
1081 * The silc_server_free_client_data now checks whether there is
1082 pending outgoing traffic for the client and purges the data to
1083 the network before removing the client entry.
1085 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1087 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1088 an client is killed from the SILC Network. Updated the protocol
1091 Added new function silc_server_send_notify_killed to the
1092 silcd/packet_send.[ch].
1094 * Added function silc_server_packet_relay_notify to relay notify
1095 packets that are destined directly to a client. In this case
1096 the server does not process the notify packets but merely relays
1097 it to the client. Affected file silcd/packet_send.[ch].
1099 Added also silc_server_packet_process_relay_notify to check
1100 whereto relay the notify. Affected file is
1101 silcd/packet_receive.[ch].
1103 * Implemented the KILL command to the server.
1107 * Added the backup schema desgined last fall to the protocol
1108 specs for everyone to see. The specification is in the
1109 *-spec-xx.txt draft and the packet type definitions for the
1110 backup routers is in *-pp-xx.txt draft. Thusly, added also
1111 new packet type SILC_PACKET_CELL_ROUTERS.
1113 * A big security problem in the implementation discovered. The
1114 signoff of an client did not cause new channel key generation
1115 which it of course should've done. The channel keys must be
1116 always re-generated when client leaves (or signoffs) the channel.
1117 The silc_server_remove_from_channels funtion now handles
1118 the channel key re-generation.
1120 * Added `sender' argument to the silc_server_send_notify_on_channels
1121 to not to send the client provided as argument. Affected file
1122 silcd/packet_send.[ch].
1124 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1126 * Implemented OPER and SILCOPER commands into the server and
1129 * Added silc_auth_verify and silc_auth_verify_data to verify
1130 the authentication directly from the authentication payload.
1131 It supports verifying both passphrase and public key based
1132 authentication. Affected file lib/silccore/silcauth.[ch].
1134 * Added `hash' field to the SilcIDListData structure. It is the
1135 hash negotiated in the SKE protocol. Affected file is
1138 * Slight redesigning of the SilcAuthPayload handling routines.
1139 Do not send SilcPKCS but SilcPublicKey as argument.
1141 * Implemented the public key authentication support to the
1142 serverconfig. The public key is loaded from the provided path
1143 and saved as authentication data to void * pointer. Thus,
1144 changed the unsigned char *auth_data to void *auth_data;
1146 * Fixed SHUTDOWN command to send the reply before the server
1147 is shutdown. :) Affected file silcd/command.c.
1149 * Fixed fatal bug in CONNECT command. The hostname was invalid
1150 memory and server crashed. Affected file silcd/command.c.
1152 * Fixed fatal bug in CLOSE command. The server_entry became
1153 invalid but was referenced later in the command. Affected file
1156 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1158 * Fixed fatal bug in failure packet handling. Server ignored
1159 the failure and thus crashed when it came.
1163 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1165 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1166 that the command may be executed only once in (about) 2 seconds.
1167 The old SILC_CF_LAG flag is same but allows command bursts up
1168 to five before limiting.
1170 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1171 server code. Various commands now includes the CF_LAG_STRICT
1172 flag to disallow any kind of miss-use of the command.
1174 * Fixed the silc_buffer_unformat to not to allocate any data
1175 if the length of the data is zero. It used to allocate the
1176 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1178 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1180 * Changed the format of AdminConnection configuration section
1181 in the server. Added username of the admin to the format.
1182 Affected files silcd/serverconfig.[ch].
1184 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1185 to return admin configuration data by host, username and/or
1188 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Implemented WHOWAS command to the server. Added the functions:
1192 silc_server_command_whowas_parse,
1193 silc_server_command_whowas_send_reply,
1194 silc_server_command_whowas_from_client and
1195 silc_server_command_whowas_from_server
1197 * Added <Client ID> argument to the WHOWAS command reply. Updated
1198 the protocol specs accordingly.
1200 * Implemented WHOWAS command and command_reply to the client
1203 Implemented the WHOWAS printing on the user interface.
1205 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Added new argument to the WHOWAS command reply, the real name.
1208 It is an optional argument. Updated the protocol specs.
1210 * Added SilcIDCacheDestructor callback that is registered when
1211 the SilcIDCache is allocated. The callback is called when
1212 an cache entry in the ID Cache expires, or is purged from the
1213 cache. Added into lib/silccore/idcache.[ch].
1215 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1216 to destruct the client entries when the cache entry expires.
1217 Other ID Cache's in server and in the client library ignores
1220 * If the ID Cache entry's `expire' field is zero then the entry
1221 never expires. Added boolean `expire' argument to the
1222 silc_idcache_add function in the lib/silccore/idcache.[ch].
1223 If it is TRUE the default expiry value is used.
1225 * Added silc_server_free_client_data_timeout that is registered
1226 when client disconnects. By default for 5 minutes we preserve
1227 the client entry for history - for WHOWAS command.
1229 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1231 * Added support to the server to enforce that commands are not
1232 executed more than once in 2 seconds. If server receives
1233 commands from client more frequently, timeout is registered
1234 to process the commands. Affected file silcd/command.c.
1235 Added new function silc_server_command_process_timeout.
1237 * Changed NICK_NOTIFY handling in client library to check that
1238 if the client's nickname was changed, so there is no need to
1239 resolve anything from the server.
1241 * Removed error printing from the WHOIS and IDENTIFY commands.
1242 If error occurs then it is ignored silently in the client library.
1243 The application, however, may map the received error to
1244 human readable error string. The application currently maps
1245 the NO_SUCH_NICKNAME error to string.
1247 * Made the command status message public to the application. Moved
1248 them from lib/silcclient/command_reply.c to
1249 lib/silcclient/command_reply.h. The application can map the
1250 received command status to the string with the
1251 silc_client_command_status_message function.
1253 * Added check to the server to check that client's ID is same
1254 as the Source ID in the packet the client sent. They must
1257 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1259 * Added dist-bzip hook to the Makefile.am to make bzip2
1260 compressed distributions.
1262 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1264 * Server now enforces the maximum length for the nickname and
1265 the channel as protocol specification dictates. 128 bytes for
1266 nickname and 256 bytes for channel name.
1268 * Moved the WHOIS printing to the application. The client libary
1269 does not print out the WHOIS information anymore, the application
1270 must do it. Renamed silc_client_command_reply_whois_print to
1271 the silc_client_command_reply_whois_save.
1273 The client's idle time is also sent to the application now, and
1274 the idle is shown on screen.
1276 * Added silc_client_command_reply_identify_save to save the
1277 received IDENTIFY entries.
1279 * Do not check for channel private keys in message sending and
1280 reception if the channel does not have the PRIVKEY mode set.
1281 Affected file lib/silclient/client_channel.c.
1283 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1285 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1286 just surfaced after chaning the JOIN procedure.
1288 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1290 * Added silc_client_get_clients_by_list to get client entries
1291 from Client ID list, that is returned for example by JOIN
1292 and USERS command replies. The application should use this
1293 function for example when JOIN command reply is received to
1294 resolve the clients already on the channel (library does not
1295 do that anymore as USERS command reply is not used in the JOIN
1296 procedure anymore). Affected files lib/silcclient/silcapi.h and
1297 lib/silcclient/idlist.c.
1299 * JOIN command reply and USERS command reply returns now SilcBuffer
1300 pointers instead of unsigned char pointers when returning
1301 the client list and mode list.
1303 * Added <Client ID> argument to the JOIN command reply, mainly
1304 for the server to identify for which client the command was
1305 originally sent. Updated protocol specs accordingly.
1307 * Added SilcDlist private_key pointer to the SilcChannelEntry
1308 in the client to support the channel private keys. Affected
1309 file is lib/silcclient/idlist.h.
1311 * Added SilcChannelPrivateKey argument to the function
1312 silc_client_send_channel_message so that application can choose
1313 to use specific private ke if it wants to. If it is not provided,
1314 the normal channel key is used, unless private keys are set.
1315 In this case the first (key that was added first) is used
1316 as the encryption key.
1318 * Implemented the support for channel private key handling.
1319 Implemented the following functions:
1321 silc_client_add_channel_private_key,
1322 silc_client_del_channel_private_keys,
1323 silc_client_del_channel_private_key,
1324 silc_client_list_channel_private_keys and
1325 silc_client_free_channel_private_keys
1327 Affected file lib/silcclient/client_channel.c.
1329 * Added the support for the private keys in the channel message
1330 sending and encryption and in the message reception and
1331 decryption. Affected funtions are
1332 silc_client_send_channel_message and silc_client_channel_message.
1334 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1336 * Added SKE's key verify callback to the client library's
1337 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1339 * Removed the statement that server (or router) must send USERS
1340 command reply when joining to the channel so that the client
1341 knows who are on the channel. Instead, the client list and
1342 client's mode list is now sent in the JOIN command reply to the
1343 client who joined channel. This is better solution.
1345 * Added function silc_server_get_users_on_channel and function
1346 silc_server_save_users_on_channel to the silcd/server.[ch].
1348 * Removed function silc_server_command_send_users from the
1351 * Do not show topic on the client library anymore. The topic is
1352 sent in the command reply notify to the application and the
1353 application must show the topic now.
1355 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1357 * Added client searching by nickname hash into the IDENTIFY and
1358 WHOIS commands in the server as they were clearly missing from
1359 them. Affected file is silcd/command.c.
1361 * Fixed a bug in private message receiving in the client library.
1362 The remote ID was freed and it wasn't supposed, now it is
1365 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1367 * Minor fix to the channel payload; allocate the data area, as it
1368 needs to be of specific length.
1370 * If the key agreement port is zero then the operating
1371 system will define the bound port. Affected files are
1372 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1374 * Added new function silc_channel_payload_decrypt into the file
1375 lib/silccore/silcchannel.[ch].
1377 * Moved the channel message etc, check from silc_packet_decrypt
1378 to applications. The library calls now a generic
1379 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1380 when the packet is either normal or special. This was done to
1381 allow more wide range of checking that was not allowed when
1382 the code was in library. Now applications can do virtually any
1383 checks to the packet and return to the library the decision how
1384 the packet should be processed. Affected files are
1385 lib/silccore/silcpacket.[ch].
1387 Added silc_server_packet_decrypt_check to the server and
1388 silc_client_packet_decrypt_check to the client library.
1390 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1391 to send with specified source and destination information.
1393 * Channel message delivery between routers was broken after the
1394 channel key distribution was fixed earlier. The channel key
1395 was used be to distributed to other routers as well which is not
1396 allowed by the protocol. Now this is fixed and channel keys
1397 really are cell specific and the channel message delivery between
1398 routers comply with the protocol specification.
1400 * Fixed various commands in server to check also the global list
1401 for the channel entry and not just the local list. The affected
1402 file silcd/command.c.
1404 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1406 * Added assert()s to buffer formatting and unformatting routines
1407 to assert (if --enable-debug) when error occurs. Affected
1408 file: lib/silcutil/silcbuffmt.c.
1410 * Changed to auto-reconnect to check whether the remote host is
1411 router and register the re-connect timeout if it is. It used
1412 to check that whether we are normal server, but router must do
1413 auto-reconnect with another router as well. Affected file
1416 * Removed the [<key len>] option from CMODE command as the cipher
1417 name decides the key length, nowadays. See the defined ciphers
1418 from the protocol specification.
1420 * Added [<hmac>] option to the CMODE command to define the HMAC
1421 for the channel. Added SILC_CMODE_HMAC channel mode.
1423 * Added [<hmac>] option for the JOIN command so that user can
1424 select which HMAC is used to compute the MACs of the channel
1427 * Added Hmac field to the Channel Message Payload. The integrity
1428 of plaintext channel messages are now protected by computing
1429 MAC of the message and attaching the MAC to the payload. The
1430 MAC is encrypted. Now, it is clear that this causes some
1431 overhead to the size of the packet but rationale for this is that
1432 now the receiver can verify whether the channel message decrypted
1433 correctly and also when private keys are set for the channel the
1434 receiver can decrypt the packet with several keys and check from
1435 the MAC which key decrypted the message correctly.
1437 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1438 lib/silccrypt/silccipher.[ch].
1440 * Added silc_hash_len to return the digest length into the
1441 lib/silcrypt/silchash.[ch].
1443 * Rewrote parts of Silc Channel Payload interface in the
1444 lib/silccore/silcchannel.[ch]. The encode function now also
1445 encrypts the packet and parse function decrypts it.
1447 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1449 * Fixed a minor formatting bug in the SKE's key material processing.
1450 It actually might have processed the keys wrong way resulting
1453 * Redefined the mandatory HMAC algorithms and added new algorithms.
1454 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1455 and hmac-md5 truncated to 96 bits. The mandatory is now
1456 hmac-sha1-96. Rest are optional (including the one that used
1457 to be mandatory). Rationale for this is that the truncated HMAC
1458 length is sufficient from security point of view and can actually
1459 make the attack against the HMAC harder. Also, the truncated
1460 HMAC causes less overhead to the packets. See the RFC2104 for
1463 * Added new [hmac] configuration section. The SKE used to use
1464 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1465 is of course wrong. The official names that must be proposed in
1466 the SKE are the ones defined in the protocol specification
1467 (hmac-sha1-96 for example). The user can configure any hmac
1468 using any hash function configured in the [hash] section. At
1469 least, the mandatory must be configured.
1471 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1473 * Added HMAC list to the SKE proposal list. It has now both
1474 hash algorithm list and HMAC list. This makes the protocol
1475 incompatible with previous versions. The SKE now seems to work
1476 the way it is supposed to work, for the first time actually.
1478 * Defined plain Hash algorithms to the protocol specification.
1481 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1483 * Implemented support for key agreement packets into the server.
1484 Added functions silc_server_key_agreement and
1485 silc_server_send_key_agreement. Other than these functions,
1486 server has nothing to do with this packet.
1488 * Added support for private message key packets into the server.
1489 Added functions silc_server_private_message_key and
1490 silc_server_send_private_message_key.
1494 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1495 called in the protocol's final callback instead in the END
1496 protocol state. This makes a little more sense and in the same
1497 time in client we can use the same protocol routines for normal
1498 key exchange and to key agreement packet handling as well.
1500 * Added to both client's and server's KE protocol context the
1501 SilcSKEKeyMaterial pointer to save the key material. We will
1502 bring the key material to the protocol's final callback by doing
1503 this. The final callback must free the key material.
1505 * Added SKE's packet_send callback into client's KE protocol
1506 context so that the caller can choose what packet sending function
1507 is used. This way we can use different packet sending when
1508 doing normal SKE when doing key agreement packet handling (in
1509 the key agreement packet handling we do not want to encrypt
1512 * Implemented the responder side of the key agreement routines
1513 in the client. The client can now bind to specified port and
1514 accept incoming key negotiation. The key material is passed
1515 to the application after the protocol is over.
1517 * Implemented the processing of incoming Key Agreement packet
1518 in the client. Added function silc_client_key_agreement to
1521 * Implemented the intiator side of the key agreement routines
1522 in the client. The client can now initiate key agreement with
1523 another remote client. The key material is passed to the
1524 application after the protocol is over.
1526 * Created client_keyagr.c to include all the key agreement
1529 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1530 SILC_TASK_CALLBACK except that it is not static.
1532 * Created client_notify.c and moved the Notify packet handling
1533 from the client.[ch] into that file.
1535 * Created client_prvmsg.c and moved all private message and
1536 private message key routines from the client.[ch] into that file.
1538 * Create client_channel.c and moved all channel message and
1539 channel private key routines from the client.[ch] into that file.
1541 * Changed silc_client_get_client_by_id_resolve to resolve with
1542 WHOIS command instead of IDENTIFY command, in the file
1543 lib/silclient/idlist.c.
1545 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Implemented the SKE's responder side to the Client library.
1549 * When FAILURE is received to the protocol do not trust it
1550 blindly. Register a timeout to wait whether the remote closes
1551 the connection as it should do it, only after that process the
1552 actual failure. This was changed to both client and server.
1554 * Added client_internal.h to include some of the structures
1555 there instead of client.h in lib/silcclient/.
1557 * Added function silc_task_unregister_by_callback to unregister
1558 timeouts by the callback function.
1560 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1562 * Some "Incomplete WHOIS info" errors has been appearing on the
1563 log files. Took away the entry->userinfo check from WHOIS
1564 reply sending. The entry->userinfo is now " " if client did not
1565 provide one. I thought this was fixed earlier but something
1566 is wrong still. Let's see if the error still appears.
1568 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1570 * Fixed a minor bug in the login when the channel key is
1571 re-generated in the server. It used to generate the key in
1572 wrong order and thus caused problems in the channel traffic.
1574 * Fixed a minor bug in channel key distsribution after
1575 KICK command. The key was not sent to the router even though
1578 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1580 * Added silc_ske_process_key_material_data as generic routine
1581 to process any key material as the SILC protocol dictates. The
1582 function is used by the actual SKE library but can be used by
1583 applications as well. This relates to the private message keys
1584 and the channel private keys since they must be processed the
1585 same way the normal SILC session keys. The protocol dictates
1586 this. Affected files: lib/silcske/silcske.[ch].
1588 Added also silc_ske_free_key_material to free the
1589 SilcSKEKeyMaterial structure.
1591 * Defined silc_cipher_set_key function to set the key for
1592 cipher without using the object's method function. The affected
1593 files: lib/silccrypt/silccipher.[ch].
1595 * Implemented silc silc_client_add_private_message_key,
1596 silc_client_add_private_message_key_ske,
1597 silc_client_del_private_message_key,
1598 silc_client_list_private_message_keys and
1599 silc_client_free_private_message_keys functions in the
1602 Added functions silc_client_send_private_message_key to send
1603 the Private Message Key payload and silc_client_private_message_key
1604 to handle incoming Private Message Key payload.
1606 * Added Cipher field to the Private Message Key payload to set
1607 the cipher to be used. If ignored, the default cipher defined
1608 in the SILC protocol (aes-256-cbc) is used.
1610 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1612 * Removed lib/silcclient/ops.h file.
1614 Redefined parts of the SILC Client Library API. Created new
1615 file silcapi.h that deprecates the ops.h file and defines the
1616 published Client Library API. Defined also private message key
1617 API and channel private key API into the file.
1619 This is the file that the application must include from the
1620 SILC Client Library. Other files need not be included by
1621 the application anymore.
1623 * Added new key_agreement client operation callback and also
1624 defined the Key Agreement library API for the application.
1626 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1628 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1629 is used by clients to request key negotiation between another
1630 client in the SILC network. If the negotiation is started it
1631 is performed using the SKE protocol. The result of the
1632 negotiation, the secret key material, can be used for example
1633 as private message key.
1635 Implemented the Key Agreement payload into the files
1636 lib/silccore/silauth.[ch].
1638 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1640 * Redefined ciphers for the SILC protocol. Added some new ciphers
1641 and defined the key lengths for the algorithms. Changed the
1642 code accordingly. The default key length is now 256 bits.
1644 * Fixed SKE key distribution function silc_ske_process_key_material
1645 when the key length is more than 128 bits. The default key
1646 length in SILC is now 256 bits.
1648 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1649 to indicate unsupported algorithm.
1651 * Renamed rijndael.c to aes.c and all functions as well.
1653 * Fixed a long standing channel key setting bug in client library.
1654 Weird that it has never surfaced before.
1656 * Fixed bug in channel deletion. If the entire channel is removed
1657 then it must also delete the references of the channel entry
1658 from the client's channel list as the client's channel entry and
1659 the channel's client entry share same memory.
1661 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Implemented CONNECT and SHUTDOWN commands in the client.
1665 * Implemented CLOSE command to the client.
1667 * Added the function silc_idlist_find_server_by_name into the
1668 files silcd/idlist.[ch].
1670 Added the function silc_idlist_find_server_by_conn into the
1671 files silcd/idlist.[ch].
1673 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1675 * DIE command was renamed to SHUTDOWN. Updated the both code
1678 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1679 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1681 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1684 * Added function silc_server_create_connection function to create
1685 connection to remote router. My server implementation actually
1686 does not allow router to connect to normal server (it expects
1687 that normal server always initiates the connection to the router)
1688 so the CONNECT command is only good for connecting to another
1691 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1693 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1694 or some other client was kicked from the channel.
1696 Implemented the handling of the notify type to both client
1699 Implemented silc_server_send_notify_kicked to send the KICKED
1700 notify. It is used to send it to the server's primary router.
1702 * Implemented the KICK command into server and client.
1704 * Added `query' argument to the silc_idlist_get_client function
1705 to indicate whether to query the client from server or not if
1708 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1709 to indicate that the client is not channel founder.
1713 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Removed the rng context from SilcPacketContext structure and
1716 changed that the packet routine uses the Global RNG API.
1718 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * Added support for quit message that client can "leave" on the
1721 channel when it quits the SILC. It is ditributed inside the
1722 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1724 Added silc_server_free_client_data that will take the
1725 signoff message as argument.
1727 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1729 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1731 * Updated parts of the protocol specification to keep it up
1734 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1736 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1737 payloads in one packet.
1739 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1740 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1741 use now the new List flag.
1743 * Also deprecated the following packet types: REPLACE_ID,
1744 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1746 * Added list support for Notify packet in server.
1748 * Added silc_server_send_notify_channel_change to send the
1749 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1750 the silc_server_send_replace_id.
1752 * Added silc_server_send_notify_nick_change to send the
1753 NICK_CHANGE notify type. Deprecates the function
1754 silc_server_send_replace_id.
1756 * Added silc_server_send_notify_join to send the JOIN notify type.
1757 Deprecates the function silc_server_send_new_channel_user.
1759 * Added silc_server_send_notify_leave to send LEAVE notify type.
1760 Deprecates the function silc_server_send_remove_channel_user.
1762 * Added silc_server_send_notify_cmode and
1763 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1764 types. Deprecates the silc_server_send_set_mode function.
1766 * Added SERVER_SIGNOFF notify type to indicate that server has
1767 quit. This means that all clients on the channel from that
1768 server will drop. This can be also used when netsplit happens.
1770 Deprecated REMOVE_ID packet type since it is not needed anymore
1773 Added silc_server_send_notify_server_signoff to send the
1774 SERVER_SIGNOFF notify type. Deprecates the function
1775 silc_server_send_remove_id.
1777 Added also silc_server_send_notify_signoff to send the
1778 SIGNOFF notify type.
1780 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1781 SILC protocol from this day on. Changed the protocol
1782 specification as well.
1784 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1785 notify type. It is used between routers to notify about
1786 topic changes on a channel.
1788 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1791 * Partly updated the protocol specification to comply with the
1792 changes now made. It is still though a bit outdated.
1794 * The JOIN notify type now takes one extra argument <Channel ID>.
1795 The packet used to be destined to the channel but now the
1796 JOIN type may be sent as list thus it is impossible to
1797 destine it to any specific channel. By adding this argument
1798 it is again possible.
1800 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1802 * Added CREDITS file. The CHANGES and CREDITS file will appear
1803 in the distribution as well.
1805 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1807 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1808 types in the server's silcd/packet_receive.c.
1810 * Implemented CMODE and CUMODE to work in router environment.
1812 * Fixed minor encoding and decoding buglet from the
1813 lib/silccore/silcmode.c.
1815 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1818 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1820 * Changed all SilcConfigServer* and silc_config_server* to
1821 SilcServerConfig* and silc_server_config*, respectively.
1824 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1826 * Associated the ID (client or server ID) to the Authentication
1827 Payload to avoid any possibility of forging. Updated the
1828 protocol specification and the code accordingly.
1830 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1832 * The RSA key length is now save to the RsaKey context in the
1833 key generation process in lib/silccrypt/rsa.c. The key length
1834 is now used to figure out the maximum size of the block allowed
1835 to be encrypted/signed.
1837 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1838 is equivalent to the silc_mp_mp2bin but does not allocate any
1841 * Changed silc_mp_mp2bin API to take length argument. If it is
1842 non-zero then the buffer is allocated that large. If zero, then
1843 the size is approximated using silc_mp_sizeinbase, which however
1846 * Created Global RNG API which is global RNG that application can
1847 initialize. After initializing, any routine anywhere in the
1848 code (including library) can use RNG without allocating a new
1849 RNG object. This was done to allow this sort of use of the
1850 RNG in code that has no chance to allocate RNG object. All
1851 applications currently allocate this and many routines in the
1852 library use this. Affected file lib/silccrypt/silcrng.[ch].
1854 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1855 it to use the Global RNG API.
1857 * Defined Authentication Payload into protocol specification that
1858 is used during SILC session to authenticate entities. It is
1859 used for example by client to authenticate itself to the server
1860 to obtain server operator privileges.
1862 Implemented this payload into the lib/silccore/silcauth.[ch].
1863 Implemented also routines for public key based authentication
1864 as the new protocol specification dictates.
1866 Moved definitions of different authentication methods from
1867 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1869 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1870 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1871 silc_pkcs_verify_with_hash functions into the file
1872 lib/silccrypt/silcpkcs.[ch].
1874 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1876 * The client entry's userinfo pointer must be always valid.
1877 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1878 will fail since it requires the userinfo. Now, the userinfo
1879 is allocated as "" if actual userinfo does not exist. Actually,
1880 it must exist and it is totally Ok to drop client connections
1881 that does not announce the userinfo. However, we will make
1882 this workaround for now.
1884 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1885 to return the remote port by socket.
1887 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1889 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1890 SILC_SERVER_PENDING_EXEC and added an new macro
1891 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1892 data or when error occurs while processing the pending command.
1894 Added new argument `destructor' into silc_server_command_pending
1895 and to the SilcServerCommandPending object. This destructor is
1896 now called after calling the pending callback or if error occurs
1897 immediately. If error occurs the actual pending callback won't
1898 be called at all - only the destructor. The destructor may be
1899 NULL if destructor is not needed.
1901 All this applies for client library code as well. Similar
1902 changes were made there as well for the pending commands.
1904 In the client, the application must now allocate the
1905 SilcClientCommandContext with the silc_client_command_alloc
1908 * Added reference counter to the SilcServerCommandContext. Added
1909 function silc_server_command_alloc and silc_server_command_dup
1912 Same type of functions added to the client library for the same
1915 * Removed the cmd_ident from IDListData away since it is now
1916 global for all connections. It is the command identifier used
1917 in command sending and with pending commands. The affected file
1920 * Added reference counter to the SilcSocketConnection objecet to
1921 indicate the usage count of the object. The object won't be
1922 freed untill the reference counter hits zero. Currently only
1923 server uses this, and client ignores it. The client must be
1924 set to use this too later. The affected files are
1925 lib/silccore/silcsockconn.[ch]. Added also the function
1926 silc_socket_dup to increase the reference counter.
1928 This was mainly added because it is possible that the socket
1929 is removed underneath of pending command or other async
1930 operation. Now it won't be free'd and proper DISCONNECTING
1931 flags, etc. can be set to avoid sending data to connection that
1932 is not valid anymore.
1934 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1935 the connection. After that it sets SILC_SET_DISCONNECTED.
1936 It is, however, possible that the socket data is not still freed.
1937 The silc_server_packet_process now checks that data is not
1938 read or written to connection that is DISCONNECTED. The socket
1939 get's freed when the reference counter hits zero.
1941 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1943 * Changed the client operation API: channel_message operation's
1944 `sender' is now the client entry of the sender, not the nickname
1945 and the `channel' is the channel entry, not the channel name.
1947 In the private_message operation the `sender' is now also the
1948 client entry of the sender not the nickname.
1950 Affected file is lib/silcclient/ops.h and all applications
1951 using the client operations.
1953 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1955 * Moved the calling of ops->connect() from connect_to_server_final
1956 into receive_new_id functin since that is the point when the
1957 client is actually allowed to send traffic to network. The
1958 affected file is lib/silcclient/client.c.
1960 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1962 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1963 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1964 (if needs broadcasting) instead of broadcasting the packets one
1965 by one which would make a burst in the network traffic.
1967 * Added `broadcast' argument to the functions in silcd/server.[ch]
1968 silc_server_create_new_channel[_with_id] to indicate whether
1969 to send New Channel packet to primary router.
1971 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1973 * Added new function into the silcd/server.[ch] files:
1974 silc_server_create_new_channel_with_id to create new channel with
1975 already existing Channel ID.
1977 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1978 lib/silccore/silcpacket.h. This packet is used t send list of
1979 Set Mode payloads inside one packet. Server uses this to set
1980 the modes for the channels and clients on those channels, that it
1981 announced to the router when it connected to it. The protocol
1982 specification has been updated accordingly.
1984 * The silc_server_new_channel did not handle the packet coming
1985 from normal server as it normally does not send that. However,
1986 when it announces its channels it does send it. Implemented
1987 the support for that.
1989 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1990 into the file lib/silccore/id.h.
1992 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1994 * Fixed memory leaks in the functions silc_idlist_del_client,
1995 silc_idlist_del_channel and silc_idlist_del_server in the file
1996 silcd/idlist.c. All of those leaked like a sieve.
1998 * Fixed some small memory leaks in the client's function
1999 silc_client_notify_by_server.
2001 * Added functions into silcd/server.c: silc_server_announce_clients,
2002 silc_server_announce_channels and silc_server_announce_server.
2003 These functions are used by normal and router server to announce
2004 to its primary router about clients, channels and servers (when
2005 router) that we own. This is done after we've connected to the
2008 These functions effectively implements the following packet types:
2009 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2010 and SILC_PACKET_NEW_ID_LIST.
2012 * Added new functions into the silcd/packet_receive.[ch]:
2013 silc_server_new_id_list, silc_server_new_channel_list and
2014 silc_server_new_channel_user_list to handle the incoming
2015 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2017 * Added support of changing Channel ID in the function
2018 silc_server_replace_id. If the server that announces a channel
2019 to the router already exists in the router (with same name but
2020 with different Channel ID), router is responsible to send
2021 Replace ID packet to the server and force the server to change
2022 the Channel ID to the one router has.
2024 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2025 client that the Channel ID has been changed by the router. The
2026 normal server sends this to the client. Client must start using
2027 the new Channel ID as the channel's ID.
2029 Implemented handling of this new type into lib/silcclient/client.c
2030 into the function silc_client_notify_by_server.
2032 * Added new function silc_idlist_replace_channel_id into the files
2033 silcd/idlist.[ch] to replace the Channel ID.
2035 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2037 * Call silc_server_command_identify_check always when processing
2038 the IDENTIFY command in silcd/command.c
2040 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2042 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2043 send keepalive packets. The packet can be sent by clients,
2044 servers and routers.
2046 Added function silc_socket_set_heartbeat into the file
2047 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2048 If not set, the heartbeat is not performed. The actual
2049 heartbeat is implemented in the low level socket connection
2050 library. However, application is responsible of actually
2053 Added silc_server_send_heartbeat to send the actual heartbeat
2054 packet into silcd/packet_send.[ch]. Server now performs
2055 keepalive with all connections.
2057 * Added silc_task_get_first function into lib/silcutil/silctask.c
2058 to return the timeout task with shortest timeout. There was a bug
2059 in task unregistration that caused problems. TODO has been
2060 updated to include that task system must be rewritten.
2062 * The client library will now resolve the client information when
2063 receiving JOIN notify from server for client that we know but
2064 have incomplete information.
2066 * Rewrote parts of silc_server_remove_from_channels and
2067 silc_server_remove_from_one_channel as they did not remove the
2068 channel in some circumstances even though they should've.
2070 * Encryption problem encountered in server:
2072 The LEAVE command used to send the Channel Key packet to the
2073 router immediately after generating it. However, the code
2074 had earlier sent Remove Channel user packet but not immediately,
2075 ie. it was put to queue. The order of packets in the router
2076 was that Channel Key packet was first and Remove Channel User
2077 packet was second, even though they were encrypted in the
2078 reverse order. For this reason, MAC check failed. Now, this
2079 is fixed by not sending the Channel Key packet immediately but
2080 putting it to queue. However, this is more fundamental problem:
2081 packets that are in queue should actually not be encrypted
2082 because packets that are sent immediately gets encrypted
2083 actually with wrong IV (and thus MAC check fails). So, packets
2084 that are in queue should be encrypted when they are sent to
2085 the wire and not when they put to the queue.
2087 However, the problem is that the current system has not been
2088 designed to work that way. Instead, the packet is encrypted
2089 as soon as possible and left to the queue. The queue is then
2090 just purged into wire. There won't be any fixes for this
2091 any time soon. So, the current semantic for packet sending
2094 o If you send packet to remote host and do not force the send
2095 (the packet will be in queue) then all subsequent packets to the
2096 same remote host must also be put to the queue. Only after the
2097 queue has been purged is it safe again to force the packet
2100 o If you send all packets immediately then it safe to send
2101 any of subsequent packets through the queue, however, after
2102 the first packet is put to queue then any subsequent packets
2103 must also be put to the queue.
2105 Follow these rules and everything works fine.
2107 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2109 * Added new function silc_server_remove_clients_by_server to
2110 remove all client entries from ID list when the server connection
2111 is lost. In this case it is also important to invalidate all
2112 client entires as they hold the invalid server entry. This
2113 fixes fatal bug when server has lost connection and will reconnect
2116 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2118 * Made some sanity checks to silc_server_daemonise like to check
2119 whether the requested user and group actually exists.
2121 * Added sanity check to SKE's silc_ske_responder_finish to check
2122 that the public and private key actually is valid.
2124 * Invalidate the client's nickname when receiving Replace ID
2125 packet and the Client ID is being replaced. This means that the
2126 server will query the nickname if someone needs it (client)
2129 * Sort the ID Cache in client library when the ID Cache data
2130 has changed (needs sorting).
2132 * Do not allow for SILC client to create several connections to
2133 several servers. The client does not support windows right now
2134 and generating multiple connections causes weird behaviour.
2136 Irssi-silc client does support windows and can handle several
2137 connections without problems, see: www.irssi.org and SILC plugin.
2139 * Fixed some places where client was added to the IDList. The
2140 rule of thumb is following (in order to get everything right):
2141 If the client is directly connected local client then the
2142 `connection' argument must be set and `router' argument must be
2143 NULL to silc_idlist_add_client function. If the client is not
2144 directly connected client then the `router' argument must
2145 bet set and the `connection' argument must be NULL to the
2146 silc_idlist_add_client function.
2148 * The funtion silc_server_packet_send_local_channel actually did
2149 not check whether the client was locally connected or not. It
2150 does that now. Fixed a bug related to LEAVE command.
2152 * Fixed Remove Channel User payload parsing bug in server's
2153 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2155 * The server's silc_server_save_channel_key now checks also the
2156 global ID list for the channel as it might not be in the local
2157 list. Fixed a bug related to LEAVE command.
2159 * Is this the end of the [<unknown>] buglet that has been lurking
2160 around for a long time? A little for loop fix in server's
2161 silc_server_command_whois_parse that is used by both IDENTIFY
2162 and WHOIS command. At least, this was a clear bug and a cause
2163 of one type of [<unknown>] buglet.
2165 * WHOIS and IDENTIFY commands call the function
2166 silc_server_command_[whois/identify]_check function even if
2167 we are not router server.
2169 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2171 * Added --with-gmp configuration option. If set the GMP
2172 is always compiled in the SILC source tree. If not set then
2173 it is checked whether the system has the GMP3 installed. If
2174 it has then the GMP won't be compiled (the system's headers
2175 and library is used), if it doesn't have it then the GMP is
2176 compiled in the SILC source tree.
2178 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2180 * Changed RSA private exponent generation to what PKCS #1
2181 suggests. We try to find the smallest possible d by doing
2182 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2183 not security fix but optimization.
2185 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2187 * Added new config entry [Identity] to fork the server and run
2188 it as specific user and group. A patch from Bostik.
2190 * Imported Dotconf configuration library into lib/dotconf.
2191 This will be used to create the SILC configuration files later.
2192 It will appear in the distsribution after this commit.
2194 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2196 * A big code auditing weekend happening. Auditing code for
2197 obvious mistakes, bugs and errors. Also, removing any code
2200 Removed files for being obsolete:
2202 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2203 inline in the file lib/silcutil/silcbuffer.h)
2205 o lib/silcutil/silcbufutil.c (the header has inline versions)
2207 Changed code to fix possible error conditions:
2209 o The buffer formatting routines now check that the destination
2210 buffer really has enough space to add the data. This applies for
2211 both buffer formatting and unformatting
2212 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2213 unformatting was changed to accomodate following rules:
2214 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2215 sent to the function while XXX_*STRING will not allocate or copy
2216 the data into the buffer. Instead it sets the pointer from the
2217 buffer into the pointer sent as argument (XXX_*STRING used to
2218 require that the pointer must be allocated already). This change
2219 makes this whole thing a bit more consistent and more optimized
2220 (note that the data returned in the unformatting with XXX_*STRING
2221 must not be freed now). The routines return now -1 on error.
2223 o Tried to find all code that use buffer_format and buffer_unformat
2224 and added return value checking to prevent formatting and
2225 especially unformatting errors and possible subsequent fatal
2228 o Changed ske->x and ske->KEY to mallocated pointers in
2229 lib/silcske/silcske.h. Fixed possible data and memory leak.
2231 o Added return value checking to all *_parse* functions. Fixed
2232 many memory leaks as well.
2234 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2235 so that buffer overflows would not happen. All code now also
2236 checks the return value as it can fail.
2238 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2240 * Added reconnection support to server if the normal server looses
2241 its connection to the router (for example if router is rebooted).
2242 The server performs normal reconnection strategy implemented
2243 to the server. Affected file silcd/server.c.
2245 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2247 * Added new packet type SILC_PACKET_SET_MODE that is used to
2248 distribute the information about changed modes (for clients,
2249 channels and clients channel modes) to all routers in the
2250 network. Updated the protocol specification accordingly.
2252 Added functions into silcd/packet_send.c and
2253 silcd/packet_receive.c: silc_server_send_set_mode,
2254 silc_server_set_mode.
2256 Added new files silcmode.[ch] into lib/silccore that implements
2257 the encoding and decoding of Set Mode Payload. Added new type
2258 SilcSetModePayload. Moved the definitions of different modes
2259 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2261 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2263 * Oops, a little mistake in server's connection authentication
2264 protocol. The protocol is not ended with FAILURE but with
2265 SUCCESS if the authentication is Ok. :) Affected file is
2268 * Implemented NICK_CHANGE notify handling in server in the file
2269 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2270 the local clients on the channel. After the changing nickname
2271 in router environment snhould work and the [<unknown>] nickname
2272 should appear no more.
2274 The silc_server_replace_id function that receives the Replace ID
2275 payload now sends the NICK_CHANGE notify type also in the file
2276 silcd/packet_receive.c
2278 * Changed WHOIS and IDENTIFY command to support the maximum amount
2279 of arguments defined in protocol specs (3328 arguments). This
2280 fixed a bug that caused problems when there were more than three
2283 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2285 * Added extra parameter, command identifier, to the
2286 silc_client_send_command so that explicit command identifier
2289 Changed that ID list routines uses specific command identifier
2290 when sending WHOIS/IDENTIFY requests to the server so that they
2291 can be identified when the reply comes back.
2293 Affected files lib/silcclient/command.[ch],
2294 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2296 * Added `sender' argument to silc_server_packet_send_to_channel
2297 to indicaet the sender who originally sent the packet to us
2298 that we are now re-sending. Ignored if NULL. Affected file
2299 silcd/packet_send.[ch].
2301 * Added some server statistics support in silcd/server_internal.h
2302 SilcServerStatistics structure and around the server code. Also
2303 send some nice statistics information when client is connecting
2306 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2308 * Fixed channel ID decoding in server's JOIN command reply in
2309 silcd/command_reply.c
2311 * Fixed braodcasting of replace ID payload to not to send it if
2312 we are standalone server in silcd/packet_receive.c.
2314 * Fixed all channel message sending routines to not to send
2315 packets to clients that has router set, since they are routed
2316 separately in the same function earlier. Affects file
2317 silcd/packet_send.c and all channel packet sending functions.
2319 * In USERS reply, res_argv[i] are not allocated, the table
2320 is allocated. Thus changed that free the table, not its
2323 * In server's whois_check and identify_check if the client is
2324 locally connected do not send any WHOIS commands - they are not
2327 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2329 * Fixed some minor bugs in client when sending WHOIS command. The
2330 arguments was in wrong order.
2332 * Removed statis function add_to_channel from server in
2333 silcd/command.c that was previously used with the joining but
2336 * Tested USERS command in router environment successfully with two
2337 routers, two servers and two clients.
2339 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Reorganized the USERS command and command reply in client library
2342 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2343 When the command is given by user we register a pending command
2344 callback that will reprocess the command after the reply has been
2345 received from the server. When reprocessing the packet we then
2346 display the information. Thus, the USERS information is displayed
2347 now in the command callback instead of in the command reply
2348 callback. The processing of the command is same as previously
2349 when server has sent the command reply in the JOINing process.
2351 * Added to USERS command in silcd/command_reply.c to join the client,
2352 we didn't use to know about, to the channel after we've created
2353 a client entry for it. Also, for clienet we did know already still
2354 check whether it is on the channel or not and add it if not.
2356 * Removed silc_server_command_join_notify as the function and its
2359 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2361 * Changed the client's pending command handling to the same as the
2362 server's pending command handling. It is also now possible to
2363 execute command reply functions from other command reply
2364 function as the function callbacks for commands and command
2365 replies are one and same. The pending commands are not static
2366 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2367 in client connection context. Thus, pending commands are server
2368 connection specific as it is convenient.
2370 Changed the function silc_client_command_pending and
2371 silc_client_command_pending_del and added new function
2372 silc_client_command_pending_check. Removed the
2373 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2376 * Added cmd_ident, current command identifier, to the client
2377 connection context in lib/silcclient/client.h to keep track on
2378 command identifiers used in command sending. Client's command reply
2379 function handling now supports the mandatory command identifiers.
2381 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2382 funtions in client to fully support pending command callbacks.
2384 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2385 as one of the arguments to the application in the command reply
2388 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2389 before first releasing SILC but came back. Now it is removed again
2390 and should come back nomore. The FORWARDED flag was used only
2391 by the JOINing procedure by forwarding the command packet to router.
2392 Now, the JOINing procedure has been changed to more generic (due
2393 to various router environment issues) and FORWARDED is not needed
2394 anymore for anything. The protocol specification is yet to be
2397 Now, removed silc_server_packet_forward from server and the flag
2398 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2400 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2402 * Renamed NAMES command to USERS command. The NAMES was named that
2403 due to historical reasons. Now it is renamed. Also, rewrote
2404 parts of the USERS command. The nickname list is not sent anymore
2405 by the server. Only Client ID and mode lists are sent in the USERS
2406 command. Changed this also to the protocol specification.
2408 The client now resolves the names and stuff after it receives
2409 the USERS list from the server when joining to the channel.
2411 * WHOIS and IDENTIFY commands has been changed to support multiple
2412 Client ID's per command. One can now search for multiple users
2413 in the network by sending only one WHOIS or IDENTIFY command.
2414 Changed the code and the protocol specifications.
2416 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2417 uses silc_server_command_whois_parse to parse the request. */
2419 * If normal server, do not parse the WHOIS and IDENTIFY requests
2420 before sending it to the router. Saves some time.
2422 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2424 * Fixed JOIN command on client library. Wrong number of arguments
2425 used to crash the client.
2427 * Added silc_server_channel_has_global function to check whether
2428 channel has global users or not.
2430 * Added silc_server_channel_has_local function to check whether channel
2431 has locally connected clients on the channel.
2433 * The silc_server_remove_from_one_channel now checks whether the
2434 channel has global users or not after given client was removed from
2435 the channel. It also checks whether the channel has local clients
2436 on the channel anymore. If it does not have then the channel entry
2437 is removed as it is not needed anymore.
2439 * The silc_server_notify now checks on JOIN notify whether the joining
2440 client is one of locally connected or global. If it is global then
2441 the channel has now global users on the channel and that is marked
2442 to the channel entry. Also, it now saves the global client to
2443 global list who is joining and JOINs it to the channel. This is
2444 for normal server, that is.
2446 Changed silc_server_send_notify_on_channel,
2447 silc_server_packet_relay_to_channel and
2448 silc_server_packet_send_to_channel check if we are normal server
2449 and client has router set (ie. global client) do not send the
2450 message to that client, as it is already routed to our router.
2452 * Implemented LEAVE notify type handling in silc_server_notify
2455 * Tested LEAVE command in router environment successfully. Tested
2456 with two routers, two servers and two clients.
2460 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2462 * Implemented SIGNOFF notify type handling in silc_server_notify
2465 * silc_server_remove_id now removes the client entry from all channels
2466 it has joined and thusly sends SIGNOFF notify type.
2468 * Rewrote the NAMES list generation in server by removing two excess
2469 loops. The lists are created now inside one loop.
2471 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * silc_server_remove_channel_user checks now also global list
2474 for channel and client.
2476 * silc_server_new_channel_user checks now both local and global
2477 list for channel and client. Fixed a bug in client id decoding.
2478 Used to decode wrong buffer.
2480 * silc_server_channel_message checks now both local and global
2481 list for channel entry.
2483 * Tested channel joining (hence JOIN) in router environment
2484 successfully. Tested with two routers, two servers and two
2487 * Tested channel message sending in router environment successfully.
2489 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Added silc_server_save_channel_key into server.[ch] to save the
2492 received channel key in Channel Key payload processing. It is
2493 also used in JOIN command reply handling.
2495 Equivalent function silc_client_save_channel_key added into
2496 client.[ch] into client library.
2498 * Changed JOIN command reply to send information whether the channel
2499 was created or not (is existing already) and the channel key
2500 payload. Changed protocol specs accordingly.
2502 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2503 the request was sent by ID and not by nickname. Crashed on
2506 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2509 now correctly save the received data.
2511 * silc_server_free_sock_user_data now notifies routers in the
2512 network about entities leaving the network.
2514 At the same time implemented functions silc_server_remove_id
2515 and silc_server_send_remove_id to receive and send REMOVE_ID
2516 packets. The packet is used to notify routers in the network
2517 about leaving entities. The ID removed will become invalid in
2520 * Added function silc_idlist_del_server into server. Removes and
2521 free's server entry from ID list.
2523 * silc_server_private_message function now checks, if we are router,
2524 that the destination ID really is valid ID, naturally.
2526 * In router when NEW_ID packet is received (for new client) the
2527 hash of the Client ID is saved in the ID Cache but the
2528 client->nickname is set to NULL, instead of putting the hash
2531 IDENTIFY command now also checks that client->nickname must be
2532 valid. If it is not if will request the data from the server who
2533 owns the client. Added new function
2534 silc_server_command_identify_check.
2536 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2537 to set the command to already allocated Command Payload.
2539 * Tested private message sending in router environment with two
2540 routers, two servers and two clients. Fixed minor bugs and now
2543 * Fixed segfault from client's NAMES command. Used to crash if
2546 * Forwarded packets must not be routed even if it is not destined
2547 to the receiver. Changed server code comply with this.
2549 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * Added `require_reverse_mapping' boolean value to ServerParams
2552 structure. If TRUE (not default) the server will require that
2553 the connecting host has fully qualified domain name.
2555 If the reverse mapping is not required and hostname could not be
2556 found the IP address is used as hostname.
2558 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2560 * Implemented version string checking to both client and server.
2561 The check is incomplete currently due to the abnormal version
2562 strings used in development version of SILC.
2564 * Changed all command functions in server to use the new
2567 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2569 * Changed char *data to unsigned char *data in ID Cache system to
2570 support binary data as ID Cache data. Changed code to support
2571 binary data in lib/silccore/idcache.c.
2573 * Renamed silc_server_packet_relay_command_reply to
2574 silc_server_command_reply as it is normal packet receiving
2575 function. Rewrote the function to accept command replys for
2576 servers and not only for clients.
2578 * Mark remote router always as registered server if we are connecting
2579 to it. Otherwise, commands sent by the router to us are ignored.
2581 * All ID List find routines now returns the ID Cache Entry pointer
2582 as well if requested.
2584 * WHOIS command works now in router environment, tested with two
2585 routers, two servers and two clients.
2587 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2588 in router environment (as it is almost equivalent to WHOIS) but
2589 hasn't been tested thoroughly. Added new functions:
2591 silc_server_command_identify_parse
2592 silc_server_command_identify_send_reply
2593 silc_server_command_identify_from_client
2594 silc_server_command_identify_from_server
2596 * Disabled route cache adding because adding two different ID's with
2597 same IP replaces the old cache entry thus giving wrong route.
2598 The entry->router->connection is always the fastest route anyway
2599 so route cache may not be needed. Of course, new routes maybe
2600 established after receiving the ID when the entry->router->connection
2601 might not be anymore the most optimal.
2603 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * Add route cache for received ID for fast routing.
2607 * Added silc_server_packet_route to route received packet on router
2608 that is not destined to us.
2610 * Renamed silc_server_get_route to silc_server_route_get.
2612 * Added id_string and id_string_len fields into SilcServer to
2613 include encoded ServerID for fast comparing without excess
2614 encoding of the ID's.
2616 * Cleaned up WHOIS command on server side. Added following static
2619 silc_server_command_whois_parse
2620 silc_server_command_whois_check
2621 silc_server_command_whois_send_reply
2622 silc_server_command_whois_from_client
2623 silc_server_command_whois_from_server
2625 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2626 arguments in command replies. All command functions should be
2627 updated to use this macro.
2629 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Minor typo fixes on command reply handling on server.
2633 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2635 * Added silc_server_command_add_to_channel internal routine to add
2636 the client to the channel after router has created the channel and
2637 sent command reply to the server.
2639 * Added generic silc_server_send_command to send any command from
2642 * Use static buffer with ID rendering instead of duplicating data.
2644 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2646 * Fixed a channel user mode bug when joining to a channel server gave
2647 everybody channel founder rights, oops.
2649 * We mark ourselves as the router of the incoming server connection
2650 if we are router ourselves. This way we can check in some packet
2651 sending functions whether it is locally connected server. For
2652 incoming router connections we put NULL.
2654 * For router sending packets locally means now always sending the
2655 packet cell wide; to local clients and local servers. For normal
2656 server sending packet locally means sending it to only local
2659 * Fixed the JOIN command to really work in router environment. If the
2660 channel is created it is always created by the router. Router is
2661 also responsible of making the initial joining to the channel,
2662 sending JOIN notify to the sending server and distributing
2663 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2664 does not exist server doesn't do anything else but forward the
2665 command to the router which performs everything.
2667 * Added silc_server_send_channel_key function to send the Channel Key
2670 * Added silc_server_create_channel_key to create new channel key. The
2671 channel key is now re-generated everytime someone joins or leaves
2672 a channel, as protocol dictates. Note: channel->key_len is the
2675 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2677 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2678 packet_receive.[ch] to separate packet sending and receiving
2679 routines. The server.[ch] now includes everything else including
2680 actual packet processing (writing and reading data) and other
2683 Renamed silc_server_private_message_send_internal to
2684 silc_server_send_private_message. The routine is still though
2685 used only to relay private messages as server does not send
2686 private messages itself.
2688 Renamed silc_server_new_channel to silc_server_create_new_channel
2689 and added new function sicl_server_new_channel that handles the
2690 incoming New Channel packet. Added also new sending function
2691 silc_server_send_new_channel to send New Channel Payload.
2693 * Added new function silc_server_notify to process incoming notify
2694 packet to the server/router. Server may then relay the notify
2695 to clients if needed.
2697 * Added new function silc_server_new_channel_user to process incoming
2698 New Channel User packet. Router will redistribute the packet and
2699 send JOIN notify to its local clients and locally connected servers
2700 if needed. Normal server will send JOIN notify to its local client
2701 on same channel when received this packet. Added also corresponding
2702 sending function silc_server_send_new_channel_user to sent the
2705 * Added boolean route argument to send_notif_to_channel and
2706 packet_send_to_channel functions to attempt to route the packet
2707 if it is TRUE and send only locally if it is FALSE.
2709 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * silc_server_replace_id now broadcasts the received replace ID
2712 packet if it is not broadcast packet already. The router must
2713 broadcast to inform other routers about changed ID.
2715 * Added backpointer to server's router into SilcServer context in
2716 silcd/server_internal.h.
2718 * Fixed silc_server_packet_broadcast to send correct broadcast
2721 * The channel key is now distributed to the local client as soon
2722 as it is received from the router (in router environment) so that
2723 no other packet may be sent for the channel until client has
2726 * silc_server_remove_channel_user now broadcasts the received
2727 Remove Channel User packet if it is not broadcast packet already.
2728 The router must broadcast to inform other routers about removed
2731 * Added users field into SilcPacketContext that is a reference count
2732 of the context. One can increase the reference count by calling
2733 silc_packet_context_dup which is now changed to just increase the
2734 reference count instead of duplicating the data. The reference
2735 count is decresed by calling silc_packet_context_free that will
2736 free the data after the reference count hits zero.
2738 For now on the packet context and everything allocated into it
2739 (including the raw packet from network) must be freed by calling
2740 the new silc_packet_context_free function. Added also new function
2741 silc_packet_context_alloc that must be used now to allocate the
2742 context. This also means that if a routine is asynchronous from
2743 silc_[client/server]_packet_parse_type the packet context must
2744 be duplicated by calling silc_packet_context_dup. Otherwise it
2745 gets free'd after silc_[client/server]_packet_parse_type returns.
2746 Also, one must remember that if packet is duplicated then its
2747 reference count must be decresed by calling the free function as
2748 many times as it was duplicated.
2750 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2751 from both client and server.
2753 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2755 * Made joining to a channel working in router environment.
2757 * Cleaned up JOIN command on server side and create function
2758 silc_server_command_join_channel internal routine to make the
2761 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Changed silc_command_pending list to SilcDList. Also, added
2764 `ident' field to SilcServerCommandPending structure to identify
2765 the reply and to call correct callback.
2767 Added silc_server_command_pending_check function to replace the
2768 corresnponding macro. The silc_command_pending list is not
2771 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2772 to set identifier to previously allocated Command Payload. It
2773 is used to set identifier for command when resending Command
2776 * Added silc_command_payload_encode_payload to encode Command
2777 Payload buffer from SilcCommandPayload structure.
2779 * Added silc_argument_payload_encode_payload to encode Argument
2780 payload buffer from SilcArgumentPayload structure.
2782 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2784 * Changed WHOIS command to support router connection on server side.
2785 The whois request is always sent to router unless the server is
2786 standalone server. After server has received the reply from the
2787 router will it send the reply to the client.
2789 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2790 broadcast received broadcast packet. The function is used only
2791 by router. The broadcast packet is always sent to the router's
2794 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2795 render given ID to printable string, for log files for example.
2797 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Made basic router to router connections working. At least they
2800 can now connect to each other but nothing really works the way
2801 they are supposed - yet.
2803 * Added new initiator token to RouterConnection configuration
2804 file in silcd/serverconfig.[ch]. It is used to tell whether we
2805 are the initiator to the remote router or whether we'll expect
2806 the other end to connect.
2808 * Moved registering of listener task to silc_server_init, hence
2809 the server starts listenning as soon as it is run, even if it
2810 does not have connections to other routers. Let's see how well
2813 * Changed default connection retry timeouts for more suitable in
2816 * Removed cipher and such arguments from silc_idlist_add_client
2817 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2818 Added new function silc_idlist_add_data to add the keys and stuff
2821 * Added SilcIDListData structure and added it to SilcClientEntry
2822 and SilcServerEntry as their first field in the structure. This
2823 way we can explicitly cast the ID entries to the SilcIDListData
2824 structure and get common data for the entries. In past, we had
2825 to first check what type of connection it is and then cast it to
2826 correct ID entry type. Now, we can directly cast the opaque
2827 pointer to the SilcIDListData (no matter what ID entry it actually
2828 is) and get the data needed.
2830 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2832 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2833 in some circumstances even if threre were timeout tasks, though not
2834 IO tasks, but tasks anyway. Now fixed.
2836 * Defined SilcServerConnection structure to hold connection specific
2837 stuff about directly connected servers and routers. The definition
2838 is currently in silcd/server_internal.h. I thought about having
2839 a bit more important role fro this struct but for now it is used
2840 only when connecting to other server (or router actually).
2842 * Added connecting retry support in server when connecting to
2843 router(s). The retry feature implement exponential backoff
2844 algorithm. Also, added SilcServerParams structure to hold default
2845 parameters for server. For now, it include these retry settings
2846 and are hard coded. After server is moded to be as Silc Server
2847 Library this structure will be more important.
2849 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2851 * Changed client librarys channel->clients table to SilcList and
2852 changed code accordingly.
2854 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * Changed client's channel table to SilcList and changed code
2857 accordingly. Also changed SilcChannelClientEntry to include back-
2858 pointer to the channel so that client entry can use that structure
2859 as list as well and we have fast cross-reference to the channel.
2860 This change dramatically decreased the complexity of channel
2861 handling with client entry and vice versa (removed one extra
2862 loop when searching for channel entry from many functions).
2864 * Changed server->sim from table to SilcDList and changed code
2867 * NAMES command can now be used from user interface. It will show
2868 the user list on the channel, neatly.
2870 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2871 Code now saves realname of the user if it becomes available.
2873 * Renamed configure.in to configure.in.pre and made ./prepare
2874 script to automatically add correct version string to
2875 configure.in which it creates from configure.in.pre.
2877 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * NAMES command reply now shows users mode with the nickname when
2882 * Moved silc_client_ch[u]mode[_char] functions from
2883 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2884 place sucks, they are utility functions and should be in some
2887 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2889 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2892 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * Added TRQ (efficient deque and list library) into lib/trq. This is
2897 a very good list library that is currently used in the SILC. Defined
2898 SilcList API over the library because I didn't like the API very
2899 much. See lib/trq/silclist.h for the API and examples of how to
2900 use the API. Fixed various places in the code to use the new
2901 SilcList API. The SilcList is meant for lists that has a structure
2902 already defined as a list. It is not suitable to add just some
2903 context to the list (in TRQ, the context is the list actually).
2905 So, I defined SilcDList that can be used for the purpose where
2906 predefined list structure does not exit. This can be used as
2907 such list. Now some context just can be added to the SilcDList.
2908 Currently this list is not used in the SILC just yet, though there
2909 are a lot places where this can replace dynamically allocated
2910 tables and I will fix these places, later, to use SilcDList.
2911 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2912 and use TRQ internally).
2914 Also fixed some annoying warning messages that the original TRQ
2915 code generated. Also minor changes to TRQ's Makefile.in.
2917 * Added support for querying by Client ID to both WHOIS and
2918 IDENTIFY commands into server, as required by the protocol.
2920 * Removed method function pointers from SilcBuffer structure. They
2921 weren't used to anything and just increased the context size for
2922 no good reason. This change also made silc_buffer_alloc and
2923 silc_buffer_free functions inline functions.
2925 * Disabled command flooding detection support until it's fixed so
2926 that it accepts commands in but does not execute them more than once
2929 * Added silc_net_localhost(), to return local hostname, into
2930 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2931 that must be initialized before calling silc_client_init.
2933 * Added new function: silc_server_send_notify_on_channels to send
2934 notify messages to all channels client has joined. It is assured
2935 that the message is sent only once per client.
2937 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2938 lib/silcutil/silcutil.[ch] as silc_format function. The new
2939 function is generic and is used by server as well, not only by
2940 the logging routines.
2942 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2943 the provided version string was not acceptable. Added new function:
2944 silc_ske_check_version into lib/silcske/silcske.h. The function
2945 must be implemented by the application (client or server) and it
2946 does not reside in the SKE library. The function checks the version
2947 string remote end sent.
2949 * Added back pointers (to opaque context and to SilcSocketConnection)
2950 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2952 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2953 duplicate packet context structure.
2955 * Changed `notify' client operation to send same arguments as client
2956 receives from server except for ID's. ID's are mapped to correct
2957 ID entry and that is returned. Also, if channel entry is not sent
2958 by server but the notify is for channel the channel entry is sent
2959 to application (otherwise application doesn't know that it is for
2960 channel (library gets it from packet's Destination ID)).
2962 * Added silc_client_remove_from_channels into client library to
2963 remove a client from all channels it has joined to. Used when
2964 received SIGNOFF notify from server. Added also new function
2965 silc_client_replace_from_channels to replace old ID entry with
2966 new ID entry on all channels. Used when received NICK_CHANGE
2969 * Fixed ID Cache list handling in silc_idlist_get_client in
2970 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2971 to get (or query) client by ID.
2973 * Updated TODO list.
2975 * Added connection authentication status message defined by the
2976 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2977 support for these into the code in client and server side.
2979 * Added generic function silc_client_send_command to send any command
2980 with variable argument list. Application should use this function
2981 to send commands if the command functions provided by the library
2982 does not suite for the application's user interface needs.
2984 * Added new `failure' client operation. Application is notified about
2985 received failure packet if client is executing a protocol. In this
2986 case the protocol's execution has failed.
2988 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2989 is required by the protocol.
2991 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2992 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2995 * Added status flag to SilcSKE object to indicate realtime status
2996 of the SKE protocol.
2998 * Application receives now exactly same command reply arguments as
2999 the library receives from server. However, if ID is received the
3000 corresponding ID entry is returned to the application (eg. Client
3001 ID is mapped to correct SilcClientEntry entry and that is returned).
3002 Changed command_reply client operation due to this change.
3004 * Changed all ID's in commands and in command replys as ID Payloads.
3005 Change affected both client and server side codes.
3007 All ID's sent in SILC network (with execption of ID's in SILC
3008 Packet header) are sent in ID Payload to support variable length
3011 * Server now notifies nick changes and notifies all clients on
3012 the channels about the new nickname (about the new Client ID,
3015 * Implemented CMODE command to change channel modes. Supports all
3016 channel modes defined by the protocol specs except ban and invite
3017 lists. (Also, private channel key mode is supported but support for
3018 setting private channel key in client is missing, thus, this mode
3019 has no effect on client side (except that server requires that the
3020 client uses private channel key and normal channel traffic does not
3023 Also, invite mode works per se, but INVITE command does not work
3024 yet correctly, so you can set channel as invite only channel but
3025 inviting clients to the channel does not work (it is yet to be
3026 thought what's the best way to do it).
3028 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3029 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3030 Implemented CUMODE command to change user's mode on the channel.
3031 Supports all modes defined by the protocol specs.
3033 * Added NAMES command reply to return users modes on the channel.
3035 * Removed unnecessary and slow ciphers from lib/silccrypt.
3037 * Set SO_KEEPALIVE option to connection sockets by default.
3039 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3041 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3042 redefined the Notify Payload into protocol specs.
3044 * Added silc_id_payload_parse_id to get ID directly from raw
3047 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3050 accept searching by Client ID as well.
3052 * Added support for LEAVE and SIGNOFF notify types in client library.
3054 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3055 to parse ID Payload from raw data.
3057 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3059 * Added flags parameter into silc_ske_assemble_security_properties
3060 function in lib/silcske/silcske.[ch].
3062 * Changed notify client operation to fit better for notify messages
3063 sent by server. The notify payload received from server is now
3064 passed to the application (after parsing it to SilcNotifyPayload).
3065 It is application's responsibility to retrieve the arguments
3066 from the payload and show the message the way it wants. The message
3067 sent by server is implementation specific.
3069 * Changed public keys to comply with the protocol specification.
3070 Old public keys are not supported anymore and are not compatible.
3072 * Removed nickname from Channel Payload as the latest draft removed
3073 it. The client must resolve the nickname from the NAMES command
3074 reply received when it joined the channel.
3076 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3078 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3080 * Fixed some errors in protocol specification drafts.
3082 * Created lib/silccore/silcnotify.c to implement Notify Payload
3083 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3084 generic payloads described by protocol specifications. The file
3085 includes implementations for ID Payload and Argument Payload.
3087 * Changed Command Payload implementation to use the new Argument
3088 Payload. Changed command_xxxx_payload to command_payload_xxxx
3089 to comply with SILC coding conventions.
3091 * Added suppport for Argument Payload handling in Notify Payload
3092 implementation as protocol requires it. Added the new support
3093 into server and client lib as well.
3095 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Added support for multiple nicknames on same channel. [n] is
3098 added locally to the nickname if there are more than one same
3099 nicknames on the channel.
3101 * Server now sends all nicknames that matched WHOIS request.
3102 Client also shows the list received from server.
3104 * Added TOPIC command to client side. User can now set and show
3105 current topic on channel.
3107 * Added MOTD command to client and server. Also, server sends the
3108 motd when client connects to the server.
3110 * Changed version strings to comply ISO 8601.
3112 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3114 * Fixed protocol error handling in client library. It should now
3115 cope even if the SKE fails for some reason.
3117 * Made new protocol specification drafts for submitting to IETF.
3119 * Implemented TOPIC command to server in silcd/command.c.
3121 * Added two new notify types into lib/silccore/silcnotify.h:
3122 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3123 notify nickname change and topic setting/change on a channel.
3125 * API change of command_reply operation in client library. The
3126 application gets now the status type received from server as well.
3128 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3130 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3132 * Cras fixed and optimized the packet handling even further and
3133 it should work now. Minor change to the prototype of function
3134 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3136 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Added new function into lib/silcutil/silcschedule.[ch]:
3139 silc_schedule_with_fd to select() a specified fd. The function
3140 returns after timeout expires or data arrives or goes. The
3141 function is used by packet routines to wait that all data is
3142 received from network.
3144 * Fixed data reading from network in lib/silccore/silcpacket.c.
3145 The code now assures that all data is read from the fd and then
3146 continues packet processing. This was a bug fix since the code
3147 used to drop some data in some circumstances.
3149 * Added new function into lib/silcclient/client.[ch]:
3150 silc_client_start_key_exchange to start key exchange after
3151 connection has been established to server. The code internally
3152 now uses this funtion but its main purpose was to provide it
3153 for applications that perform their own connecting. After
3154 application has created a connection it merely calls this
3155 function to start the key exchange between client and server.
3156 The library takes care of everything else after that.
3158 Updated also lib/silcclient/README to explain the usage of
3161 * Do not send to application information that connection has
3162 been established. Application gets notified it by connect
3165 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3167 * Applied cras's patch to add silc_schedule_one function. The
3168 function runs scheduler once and returns.
3170 * Fixed the scheduler after cras messed it up. The timeout
3171 handling works now as it's supposed to work.
3173 * Added into lib/silccore/ silcnotify.h to include notify
3174 message types support. Changed silc_server_send_notify*
3175 functions, in server.[ch], to support those new notify types.
3176 Added the support for the notify types into client library,
3177 as well. Added new notify client operation into ops.h in
3180 * Changed silc_server_packet_send_to_channel to send normal
3181 packets instead of just channel message packets. The function
3182 is now used to send the notify packets to channels. It is not
3183 used to send channel message packets anymore, as server never
3186 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3187 va_arg()s as it seems to require it nowadays. I guess, if SILC
3188 is compiled with older va_arg() the new code should work anyway.
3190 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3192 * Splitted core library. Core library (lib/silccore) includes
3193 now only SILC protocol specific core (and common) components.
3194 Created new utility library (lib/silcutil) that includes more
3195 generic purpose stuff. The stuff for util library was taken
3196 from the old core library. This was minor and easy split.
3198 * Created SILC Client Library (lib/silcclient) that includes
3199 implementation of the SILC client without user interface. This
3200 was major move from silc/ directory. The code has been changed
3201 so that it is transparent towards the user interface. The
3202 silc/ directory includes now the same user interface as before
3203 and it uses the new client library. Read lib/silcclient/README.
3204 Basicly, the client library performs everything else related
3205 to SILC except user interface handling. Also, configuration
3206 files are considered to be part of user interface and library
3207 does not handle them.
3209 This change also changed a lot of structures, function naming etc.
3210 Most important change was that SilcClientWindow object was
3211 renamed to SilcClientConnection in the client library. Created
3212 also new file lib/silcclient/ops.h. Also added new files
3213 silc/local_command.[ch] and silc/client_ops.[ch].
3215 All these changes were made to make it easier for user interface
3216 designers to create what ever user interface for the SILC client
3219 It is also expected that the server will be moved to lib
3220 directory as well and SILC Server Library will be created;
3221 sometimes in the future.
3223 * Removed Local commands from lib/silccore/silccommand.h as
3224 they are application specific and new client library does not
3225 handle any of those anymore.
3227 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3228 old client implementation in silc/.
3230 * Added support for callback functions in SILC_LOG_* macros.
3231 Application can now set its own callbacks that will be called
3232 instead of using the default functions that will always print
3233 the debug messages to stderr (or stdout). Also, debugging can
3234 now be disabled by setting silc_debug to FALSE and re-enabled by
3235 setting it to TRUE. Note, that logging will still work even
3236 if debugging is disabled.
3238 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3239 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3240 silc_log_reset_debug_callbacks.
3242 * To enable debugging in silc client one must give now -d
3243 option on command line.
3245 * Changed silc_schedule_init to automatically allocate task queues
3246 if they are not allocated before calling it.
3248 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3250 * Added GMP 3.1 into math library.
3252 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3254 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3255 a channel in SILC network. The packet is used by servers and
3256 routers to notify other routers that user has left a channel.
3257 This little feature was missing until now. Added the feature
3258 to protocol specification as well.
3260 Added functions: silc_server_send_remove_channel_user and
3261 silc_server_remove_channel_user into server.[ch].
3263 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3264 lib/silccore/silcpacket.h. However, they are not implemented
3267 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3269 * Fixed joining to a channel and sending channel messages
3270 between server and router. The channel message sending should
3271 now work inside a cell.
3273 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Fixed the private message sending between server and router.
3276 The private message sending should now work inside a cell.
3278 * Added silc_server_replace_id into server.[ch] to replace
3279 existing ID in the SILC network.
3281 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3282 and silc_idlist_replace_server_id into idlist.[ch] in server.
3284 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3286 * Fixed the server to server connections. Server can again now
3287 connect to router. Router to router connections probably does
3290 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Added dynamic protocol registering support. Now protocols can
3293 registered and unregistered on the fly. Patch by cras.
3295 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3297 * Added lib/contrib directory to hold routines that some platforms
3298 don't have but are needed by SILC.
3300 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3301 into lin/contrib to provide getopt() and getopt_long() for
3302 those who don't have it.
3304 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Added AWAY command to client. When away message is set and
3307 client receives a private message packet the client automatically
3308 replies to the sender with the away message.
3310 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3311 bug seemed to be the cause of recent problems when compiling
3314 * Added version detection support to SKE protocol specification
3315 and added the new changes to the SKE implementation as well.
3316 There were other minor changes in the SKE protocol as well.
3318 Many changes in lib/silcske/silcske.[ch] and in
3319 lib/silcske/payload.[ch].
3321 * Added ^U functionality, clear input line. Patch from cras.
3323 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Mainly small bugfixes on core library. Fixed some debugging
3326 logging and buffer overflow in silclog.c.
3328 * Updated config.sub and config.guess on the distribution tree.
3330 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Added command lagging support in server. Client may execute
3333 commands now only once in two seconds.
3335 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Optimized packet reception. MAC computation and checking is now
3338 also more optimized. A lot previously duplicated code is now
3339 used as generic by both client and server.
3341 * Fixed key pair generation in clientutil.c
3343 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Added into lib/silccore/silcbufutil.[ch] new function;
3346 silc_buffer_realloc.
3348 * Moved generic packet sending/encryption functions to
3349 lib/silccore/silcpacket.[ch] from client and server. Some
3350 rewriting of the functions.
3352 * Moved all generic packet reception/decryption functions to
3353 lib/silccore/silcpacket.[ch] from client and server. The
3354 packet processing is now much cleaner in both client and server.
3355 These were major changes in both client and server.
3357 * Created many common functions in server to do packet sending.
3358 Previously code were duplicated a lot, this has been removed
3361 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Rewrote major parts of the ID cache system. Don't know
3364 whether it is better now or not but at least the API is more
3367 * Major rewrite on ID cache stuff on client because of the ID
3368 cache API changes. Added idlist.c to client.
3370 * Also major rewrite on ID cache stuff on server as well.
3371 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3372 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3373 in hand, instead they are all put into the ID cache system now.
3374 All server_idlist_* routines uses ID cache now instead of
3375 traversing its own lists (those lists does not exist anymore).
3376 SilcIDList though still exists. Also, SilcXXXEntry's are
3379 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Finally made the SKE implementation compliant to the protocol
3382 specification. All mp integers are now binary encoded as
3383 opposed being HEX encoded.
3385 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3388 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3389 functions: silc_[encode/decode]_pem. Also added function
3390 silc_encode_pem_file to PEM encode with newlines ('\n') for
3393 * SILC public keys are now encoded either PEM or binary. Same
3394 option is for private keys as well. By default private keys
3395 are binary encoded and public keys PEM encoded. Silly HEX
3396 encoding were removed.
3398 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3399 function to create fingerprints.
3401 * Fixed a bug in SHA1; does not change the original data anymore.
3403 * Partly implemented INFO command on client and server side.
3404 Fixed CLEAR command. Changes to SERVER command; show current
3405 server(s) when giving command without arguments. Added
3406 VERSION command to client.
3408 * Added check to server that unregistered connections cannot
3409 execute commands (unless it is specificly allowed).
3411 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3413 * Fixed screen refresh.
3415 * Fixed channel joining bug from client. On some circumstances
3416 client tried to join to a channel it had already joined.
3418 * Added public key verification process into client's protocol.c.
3419 The client now verifies the public key from user and saves
3420 it into ~./silc/serverkeys/ directory.
3422 Added into: clientutil.[ch]: silc_client_verify_server_key.
3424 * Changed SKE protocol's silc_ske_initiator_finish function
3425 to accept callback function that verifies the received public
3426 key. Removed old silc_ske_verify_public_key function.
3428 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3431 silc_pkcs_private_key[_data]_set.
3433 * Made the password and public authentication more cleaner in
3434 server's protocol.c.
3436 * Removed historic and obsolete protocol `channel_auth' from
3437 both client and server.
3439 * Removed wrong way of sending command status messages from
3440 server to client in server's command.c. The old way violated
3441 protocol specification.
3443 Changes to silccore/silccommand.[ch]: removed
3444 silc_command_encode_status_payload -> not needed anymore,
3445 changed silc_command_encode_payload_va to accept extra
3446 argument on variable argument list. The argument type must
3447 now be provided to the function. Also, added new function:
3448 silc_command_encode_reply_payload_va which is same as
3449 normal command_encode_payload_va except command status type
3450 is provided as extra argument.
3452 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Added ~./silc directory handling. The directory includes the
3455 public and private keys for the client.
3457 Added silc_client_check_silc_dir, silc_client_create_identifier
3458 and silc_client_load_keys.
3460 * Implemented SILC protocol compliant public key. Added public
3461 and private key saving to and loading from files.
3463 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3464 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3465 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3466 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3467 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3469 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3470 silc_pkcs_load_[public/private]_key.
3472 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3474 * Added silc_server_get_route (route.[ch]) to get connection
3475 data for the fastest route for given ID.
3477 * Implemented INVITE command on client and server. The command
3478 were re-defined in the SILC Protocol Specification and the
3479 implementation now complies with the specification.
3481 * Implemented PING command on client and server.
3483 * Implemented NAMES command on client and server. The server side
3484 supports currently only normal server not router server yet.
3485 Some changes to NAMES definition in SILC protocol specification.
3487 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Implemented LEAVE command on client and server.
3491 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3492 again. This change was made to the protocol as well. Server
3493 should not violate the protocol specification anymore.
3495 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3498 was tested. SOCKS4 was not but should work anyway.
