1 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Merged dotconf version 1.0.2 into lib/dotconf.
5 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7 * Do not compile anything in lib/silcsim/* if the SIM support
8 is not enabled. The tree should now compile without problems
11 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
13 * Compiled the SILC under cygwin. Compiled and tested briefly
14 without problems. More tests needed. The SIMs didn't compile
17 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
19 * Fixed possible crash in silc_get_username in the
20 lib/silcutil/silcutil.c.
22 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
24 * Fixed a va_arg in silc/client_ops.c.
26 * Oops, RC5 routines were named AES and caused some problems
27 when not using SIM's. Affected file lib/silccrypt/rc5.c.
29 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
31 * Added new SilcIDIP structure into the lib/silccore/id.h and
32 replaced the old `ip' fields from all SILC ID's to that type.
33 This is a step towards IPv6 support.
35 The silc_id_get_len takes now the ID as an extra argument.
36 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
37 both IPv4 and IPv6 based ID's.
39 The affected files are lib/silccore/id.[ch] and other files
40 around the tree using these routines.
42 * Removed the ID length arguments in server from various
43 silc_server_send_notify_* routines -> they are not needed
46 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
48 * Fixed memory leak in silc_encode_pem_file in the file
49 lib/silcutil/silcutil.c.
51 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
53 * Check minor version as well in the SKE. Affected files are
54 silcd/protocol.c and lib/silcclient/protocol.c.
56 * Added --identifier option to the server so that an identifier
57 can be when creating the public key for the server. Affected
58 file is silcd/silcd.c.
60 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
61 lib/silccrypt/silcpkcs.c.
63 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
65 * Register default ciphers and stuff when using -C option with
66 the server. Affected file sildc/silcd.c.
68 * Put back the servers public key filename format, it is better
69 than the new one. For now, the client keys are saved with the
70 new filename format. The affected file silc/client_ops.c.
72 * Implemented the Cipher API for the rest of the ciphers that
73 did not implement it or implemented it the wrong way.
75 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
77 * Register default ciphers and stuff when using the -S option
78 in the client. Affected file silc/silc.c. Same also when
79 creating new key pair with -C option.
81 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
83 * Fixed the silc_verify_public_key client operation function to
84 save the public keys differently. The fingerprint is now
85 used as filename and not the hostname. This way also the
86 client keys are saved uniquely and not with hostnames. The
87 affected file is silc/client_ops.c.
89 * Trimmed the silc_hash_fingerprint function to remove extra
90 whitespaces from the end of the fingerprint. The affected
91 file is lib/silccrypt/silchash.c.
95 * Added silc_cipher_register_default function to register all
96 default ciphers. It can be used when configuration files
97 does not exist and the application does not want any specific
98 ciphers in any specific order.
100 The SilcDList is now used as silc_cipher_list dynamically
101 allocated cipher list. Removed the static list all together
102 and now all ciphers must be allocated to the dynamic list.
103 The silc_cipher_alloc routine was changed to check only the
106 All silc_cipher_* routines that used to return int returns
109 The affected files lib/silccrypt/silccrypt.[ch].
111 * The same thing was done to silc_hash_* as for silc_cipher_*
112 routines. Affected files lib/silccrypt/silchash.[ch].
114 * The same thing was done to silc_pkcs_* as for silc_cipher_*
115 routines. Affected files lib/silccrypt/silcpkcs.[ch].
116 Added also silc_pkcs_[un]register[_default] functions.
117 Removed the data_context from the PKCS API.
119 * Added silc_hmac_register_default function to register default
120 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
121 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
122 to unregister all hmacs at once.
124 * Register the default ciphers, hash functions, PKCSs and HMACs
125 if client's configuration file does not exist. The affected
128 * The client did not load the hash functions from the SIM
129 modules at all. Added support for this. Affected file is
132 * When decoding public key with silc_pkcs_public_key_decode, check
133 the supported algorithm only if PKCS are registered. Affected
134 file lib/silccrypt/silcpkcs.c. The same was done with the
135 silc_pkcs_private_key_decode.
137 * Fixed the SILC List routines to keep the list always in order.
138 It used to change the list's order when traversing the list but
139 not it preserves the order. Affected file lib/trq/silclist.h.
141 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
143 * Added the client library to use the SilcSocketConnection's
144 reference counter (by silc_socket_dup) to prevent the bug that
145 the socket object may be freed underneath async operation.
147 * The name resolv library checking fixes in the configure.in.pre.
150 * Created new version of the protocol drafts for future
151 development. The -03 drafts are the ones that will be changed
152 in the trunk now and the -02 will remain as they are.
154 * Send list of CUMODE notifys to the router when announcing
155 the channel users to the router. Affected file silcd/server.c.
156 If the router receiving channel founder CUMODE for a channel
157 that already has channel founder it will send CUMODE notify
158 to the sender to remove the channel founder rights from the
159 announced client. Affected file silcd/packet_receive.c.
161 * The CUMODE notify may now use Server ID as well as the entity
162 who changes the mode. Updated protocool specs.
164 * Updated INSTALL and README files.
166 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
168 * New web pages in the http://silc.pspt.fi. The pages was
173 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
175 * Implemented the [DenyConnectin] config section in the server.
176 Added silc_server_config_denied_conn to check whether incoming
177 connection is denied. Affected file silcd/serverconfig.[ch].
179 * Do not check the ports when checking the incoming configuration
180 data if the port is 0, meaning any. Affected file is
181 silcd/serverconfig.c.
183 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
185 * Fixed buffer overflow in silc_string_compare in the file
186 lib/silcutil/silcutil.c.
188 * Fixed double free in silc_server_command_leave in the file
191 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Fixed the version checking in the server. Affected file is
196 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
198 * Fixed the configuration data fetching when accepting new
199 connections in the server. Affected file silcd/server.c.
201 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
203 * Added `sender_entry' argument to the function
204 silc_server_packet_relay_to_channel so that we can check
205 whether some destination actually belongs to the same route
206 the sender belongs (ie, we must not resend the packet to the
207 sender). Affected file silcd/packet_send.[ch].
209 * Added `servername' field to the SilcClientEntry in the server
210 to hold the name of the server where client is from. Affected
211 file is silcd/idlist.h.
213 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
215 * Moved the channel message encrypting in the router betwen
216 router connections from silc_server_channel_message to the
217 silc_server_packet_relay_to_channel since we want to check
218 whether we have anybody channel before encrypting anything.
219 Affected files silcd/packet_[receive/send].c.
221 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
223 * Fixed the [AdminConnection] server config section to support
224 multiple entries. Affected file silcd/serverconfig.c.
226 * Added support into the server to check the validity of the
227 incoming connection before executing any KE or authentication
230 * The connection configuration is now saved to the KE and
231 connection auth protocol contexts and not fetched anymore in
232 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
234 * The local hosts listenning address and port is also resolved
235 now when starting the server. We want to have the socket object
236 to include the real address and port for the listener. Added
237 new function silc_net_check_local_by_sock into the files
238 lib/silcutil/silcnet.[ch].
240 * Fixed a broadcast bug in server -> do not broadcast if we
243 * Fixed a routing bug. Do not route broadcast packets ever.
244 Broadcast packets must be processed always and not routed since
245 they may be destined to some other host than yourself and thus
246 would get routed without no good reason. Affected file is
249 * Added function silc_server_config_is_primary_route to check
250 whether primary router connection has been configured (a router
251 configuration that we are initiating). If there is not, we
252 will assume that there is only two routers in the SILC network
253 and we will use the incoming router connection as our primary
254 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
256 * Changed the order of the broadcasting. Broadcast _after_ the
257 packet has been processed not before. Affected file is
260 * Fixed a [ClientConnection] parsing bug. The port was never
261 parsed correctly thus resulting to port 0. Affected file
262 silcd/serverconfig.c.
264 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
265 argument and did not set the broadcast packet flag. Affected
266 file silcd/packet_send.c. Fixed same bug in the function
267 silc_server_send_notify as well.
269 * If we receive NEW_ID packet for our own ID in the server, ignore
272 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
276 * Removed the nickname from the Private Message Payload.
277 Updated the code and the protocol specs.
279 * Updated protocol specs for submitting to the IETF.
281 * Tweaked the Random Number Generator a bit. Affected file
282 lib/silccrypt/silcrng.c. Exported a new function
283 silc_rng_[global]_add_noise which can be used to add more
286 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * Do not parse packets with different timeout when protocol
289 is active -> may cause problem with rekey. Affected file
292 * When server receives signoff notify it must not create
293 new channel key if the client is on any channels since the
294 sender of the signoff notify will create it.
296 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
298 * Added printing of error messages during SKE protocol from the
299 failure packet sent by server during SKE. Affected file
302 * Removed the client's failure_callback handling with timeout
303 and handle it immediately when received.
305 * The SKE library returned wrong type in SUCCESS and FAILURE
306 packets. They must be 32 bit MSB not 16 bit MSB.
308 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
310 * Ok, rewrote the logic of the re-key and now it seems to work.
311 I tested it on high traffic with frequent re-keys without
312 problems. Added hmac_receive (and renamed hmac to hmac_send)
313 in SilcClientConnection in lib/silcclient/client.h and
314 in SilcIDListData in silcd/idlist.h. Also, removed the
315 SilcPacketParserContext's cipher and hmac fields as they are
316 not needed anymore and actually caused some problems when
317 the ciphers and hmac's changed underneath the packet parser.
319 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
321 * If re-key protocol is active then process the incoming packets
322 synchronously since we must assure that icoming packets encrypted
323 with the old key is processed before the new keys is set to
324 use. This is true other packets than for REKEY packets.
325 Affected file silcd/server.c. The same was done to client library
326 as well, affected file lib/silcclient/client.c.
328 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
330 * Fixed bug in client and server to accept the force send if
331 the packet is send from silc_[server/client]_packet_process
332 function. Otherwise the packets are never delivered, oops.
334 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
336 * Disable force sending of packets when REKEY protocol is active.
337 We must assure that no packet is sent directly when rekey is
338 performed. All packets must be sent through packet queue.
339 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
340 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
341 function is silc_[server/client]_packet_send_real to check
344 * Replaced the SIM paths from example config files to
345 /usr/local/modules. Also, make install creates now
346 /usr/local/silc/logs directory to hold all the SILC server
349 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
351 * Made the configure.in.pre work on Solaris. Patch by salo.
353 * Made all ciphers compatible with non-x86 machines. Defined
354 CBC mode macros into lib/silccrypt/ciphers_def.h.
356 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * Fixed the make install.
360 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
362 * When MAC computation fails the silc_packet_decrypt returned 0
363 even though it was supposed to return -1. Fixed this. The
364 affected file is lib/silccore/silcpacket.c.
366 * Do not replace the config files in /etc/silc (in make install)
367 if they already exist. Affected file ./Makefile.am.
369 * Do not send re-key packets immediately but through packet queue.
370 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
372 * Changed silc_net_check_host_by_sock to return FALSE if the
373 IP/DNS could not be resolved. Though, it returns the IP address
374 now even if it could not resolve it (but returns also FALSE).
375 Affected file lib/silcutil/silcnet.[ch].
377 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
379 * Added silc_pkcs_decode_identifier to decode the public key's
380 identifier. Affected file lib/silccrypt/silpkcs.[ch].
381 Added also silc_pkcs_free_identifier. Added also new context
382 SilcPublicKeyIdentifier.
384 * Added -S option to the silc client. It is used to dump the
385 contents of the specified public key file.
387 * Changed the PKCS api to return the public key length when
388 setting the public key.
390 * Fixed a fatal bug in the public and private key file loading.
391 Affected file lib/silccrypt/silcpkcs.c.
393 * Execute the packet parsing for client with zero (0) timeout
394 if the protocol is active. Affected file silcd/server.c.
396 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
398 * Made the key generation options to the silcd program. Added
399 -C option, equivalent to client's option.
401 * Added new [ServerKeys] config section to the server. It
402 configures the server's public and private key.
404 * Defined generic Public Key Payload into the protocol
405 specification to send specific type of public keys and
408 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
409 public key or certificate.
411 * Implemented the GETKEY command to the server and to the
412 client library and on user interface.
414 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
416 * Made preliminary `make install' work.
418 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
420 * Added SilcServerRekey context into silcd/idlist.h.
422 * Added the PFS support as defined in the specification to the
423 SKE protocol. Affected files lib/silcske/*.c.

426 the number of the SKE group that is used with PFS in re-key.
427 Affected file silcd/idlist.h.
429 * Added PFS re-key support to the server. Affected file is
432 * Added silc_protocol_cancel to cancel execution of the next
433 state of the protocol. Affected file is
434 lib/silccore/silcprotocol.[ch].
436 * Added the re-key support with and without PFS to the client
437 library. Re-key is performed once in an hour, by default.
439 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
440 Added silc_client_rekey_callback and silc_client_rekey_final.
441 Affected files are lib/silcclient/protocol.[ch] and

444 * Removed the `hmac_key' and `hmac_key_len' fields from the
445 SilcClientConnection structure; not needed. Affected file is
446 lib/silcclient/client.h.
450 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
452 * Do not ask whether user wants to use the negotiated private key
453 for private messages, just use it. Affected file is
454 silc/local_command.c.
456 * Added `send_enc_key' and `enc_key_len' fields to the
457 SilcIDListData structure since they are needed in the re-key
458 phase. Affected file is silcd/idlist.[ch].
460 * Implemented the simple re-key protocol into the server.
461 Affected files silcd/server.c and silcd/protocol.[ch]. The
462 re-key will be performed once in an hour, by default.

465 Added silc_server_rekey, silc_server_rekey_callback and
466 silc_server_rekey_final.
468 * Removed Tunneled flag from the protocol. Updated the code
469 and the specifications.
471 * Adde `pfs' field to the SilcIDListData to indicate whether
472 the PFS is to be performed in the re-key. Affected file is
475 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
477 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
478 int64 of at least the xintXX size. If void * is less that 4
479 bytes uint32 * will be used. Defined bool as boolean.
481 * Changed _ALL_ unsigned long and unsigned int to uint32,
482 unsgined short to uint16 in the source tree.
484 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
485 not handle clients that has entry->data.registered == FALSE.
486 They are not in the network anymore. Affected file is
489 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
491 * Implemented the sending of the SERVER_SIGNOFF notify in the
492 server. Affected file is silcd/server.c.
494 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

499 Affected file silcd/packet_receive.c.
501 * Implemented the SERVER_SIGNOFF notify handling in the client
502 library. Affected file lib/silcclient/client_notify.c. Also,
503 implemnted the printing of the SERVER_SIGNOFF info to the
504 application. Affected file silc/client_ops.c.
506 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
507 if the deleting was successful. Affected file silcd/idlist.[ch].
509 * Added support for public key authentication in the connection
510 authentication protocol in the client library. Affected file
511 lib/silcclient/protocol.c.
513 * Changed the server's silc_idlist_get_clients_by_* interface
514 to support already allocated array so that new entries may be
515 added to pre-allocated array. Affected file silcd/idlist.[ch].
516 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
519 * All command reply functions in the server now calls the
520 pending command callback even if error occured. This way the
521 error will be delivered to the client as well. Affected files
522 silcd/command.c and silcd/command_reply.c.
524 * Fixed INFO command to return local server's info if no server
525 was provided. Affected file lib/silcclient/command.c.
527 * Removed RESTART command for good. Updated the code and the
530 * Rewrote parts of the task system. It is a bit simpler now.
531 Removed unsued task priorities. The affected files are
532 lib/silcutil/silctask.[ch].
534 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Moved the USERS printing from the library to the application.
537 Affected files lib/silcclient/command.c and silc/client_ops.c.
539 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
543 * Added channel key re-key support. The re-key is perfomed
544 only by the router and is done once in an hour. Added `rekey'
545 field to the SilcChannelEntry in the server. Affected files
546 silcd/server.c and silcd/idlist.h.
548 * Added silc_task_unregister_by_context into the file
549 lib/silcutil/silctask.[ch].
551 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
553 * Added SILC_UMODE_GONE mode to indicate when the client is not
554 present in the SILC network. Added also support to the local
555 command AWAY that will set this mode. Added support of showing
556 "xxx is gone" in WHOIS command. The USERS command shows the
559 * Fixed setting server and router operator privileges in the
560 server's UMODE command. Affected file silcd/command.c.
562 * Merged the SKE KE1 and KE2 payloads into one payload. The
563 new KE payload is equivalent to the old KE2 payload.
565 Cleaned up the SKE Start Payload parsing. It now uses the
566 simple buffer unformatting to do the parsing. A lot faster
569 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
570 to the SKE that is used to indicate whether both of the SKE
571 parties should perform authentication. By default only the
572 responder performs authentication. By setting this flag also
573 the initiator must do authentication. By default it is unset
574 since in normal SKE case, client to server connection, only
575 the responder should do authentication. When doing SKE between
576 two clients both should perform authentication. Updated the
577 code and the protocol specs.
579 * A little fix to IDENTIFY command in the server. Search the
580 client first by hash not nickname. Affected file is
583 * Fixed the silc_client_close_connection to support closing
584 the client to client connections wihtout deleting too much
585 data. Affected file lib/silcclient/client.c.
587 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
588 are received if protocol used to be active but is not anymore
589 the application would crash due to NULL pointer dereference.
590 Affected files silcd/server.c and lib/silcclient/client.c.
592 * Added `hash' field to the SilcClientConnection to include
593 the hash function negotiated in the SKE protocol.
595 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
596 to set the channel founder authentication data. A client can
597 claim the founder rights later by providing the authentication
598 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
599 This way the channel founder can regain the channel founder
600 privileges even it is left the channel. This works only on
601 local server and the client must be connected to the same
602 server to be able to regain the founder rights. Updated the
603 protocol specs accordingly.
605 Added support to the CMODE command in the client to set the
606 founder auth data. Read the README to see how to set it.
608 Added support to the CUMODE command to claim the founder
609 rights. Read the README to see how to do it.
611 Added support for the founder authentication to the Channel
612 Entry in the server. Affected file silcd/idlist.h.
614 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
615 server's CMODE command. Affected file silcd/command.c.
617 * Added the following new functions into lib/silccore/silcauth.[ch]:
618 silc_auth_get_method and silc_auth_get_data.
620 * The server now saves the remote hosts public key to the
621 SilcIDListData pointer. Affected file silcd/protocol.c.
623 * The normal server now does not remove the channel entry from
624 the cache if the founder authentication data is set. It used
625 to remove it if the founder was the last one on the channel on
626 the server and left the channel. The auth data is saved and
627 if the channel is re-joined later the old entry is used with
628 the old auth data. Affected files silcd/command_reply.c and
631 * Removed the `pkcs' field from the SilcIDListData structure
632 in the server; it is not used. Affected file silcd/idlist.h.
634 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
636 * Fixed packet processing on slow links. Partial packets were
637 never re-processed because the incoming data buffer was cleared
638 by the application. Application must not directly clear the
639 sock->inbuf, the packet processing routines handle it. Fixed
640 this in client library and in server.
642 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
644 * Fixed the WHOIS and IDENTIFY send reply function to really
645 check whether to send list or just one entry. Affected file
648 * Cleaned up the LEAVE command's channel key distribution. The
649 affected file silcd/command.c.
651 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
652 can enforce the channel mode as well. In that case the ID
653 includes the ID of the server. The code now enforces the
654 mode change if the router have different mode than the server.
656 * The notify client operation with CMODE_CHANGE notify can now
657 return NULL client_entry pointer if the CMODE was not changed
658 by client. Application must check for this.
660 * Added <Server ID> argument to INFO command to support server
661 info fetching by Server ID.
663 * Added silc_server_announce_get_channel_users to get assembled
664 packets of channel users of the specified channel. Affected
665 file silcd/server.[ch].
667 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
668 was freed underneath the ID Cache.
670 * Re-announce clients when the server received CHANNEL_CHANGE
671 notify from the router. Affected file silcd/packet_send.c.
673 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
675 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
676 crashed since it did not handle the fact that there is no cipher
677 called "3" and didn't check the error condition. Now fixed.
679 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
680 flag. It can be used to send message requests.
682 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
684 * Implemented the RESTART command in the client.
686 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
687 notice type messages. Added notice printing to the user
690 * The channel keys are not re-generated if the channel's mode
691 is PRIVKEY, ie private key on the channel exists. Affected
692 files silcd/server.c and silcd/command.c.
694 * Fixed a little bug in channel message delivery when channel
695 private keys are set in the server. Affected file is
698 * Changed the setting on channel->on_channel = TRUE from the
699 silc_client_save_channel_key to the JOIN command reply. The
700 key payload is not received if the private channel key is set.
701 Affected file lib/silcclient/command_reply.c and the
702 lib/silcclient/client_channel.c.
704 * When the CMODE_CHANGE notify is sent and the channel private
705 key mode is removed the channel key must be re-generated in
706 other cells as well. Added this support for the router in the
707 silcd/packet_receive.c.
709 * Added new local command NOTICE to send notice message on
710 channel. Affected file silc/local_command.[ch].
712 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
714 * Added new local command ME to the client. It is used to send
715 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
716 some action. Affected file silc/local_command.[ch].
718 * Changed channel_message and private_message client operations
719 to deliver the message flags to the application. Added also
720 the `flags' arguments to the silc_client_send_channel_message
721 and silc_client_send_private_message functions. Affected file
724 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
726 * Redefined the Private Message Payload to support private message
727 keys and to support the new private message flags. Updated
728 the protocol specs. Flags makes it possible to have for example
731 * Added new type SilcPrivateMessagePayload and defined an API
732 for it in the lib/silcclient/silcprivate.[ch].
734 * Tested private message private keys successfully. Tested the
735 private message key set, unset and list commands with the new
738 * Redefined the Channel Message Payload to include the channel
739 message flags (equal with private message flags) to support
740 for example CTCP style messages.
742 * Defined some of the message (for channel and private message)
743 flags. Updated the protocol specs and added the flags to the
744 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
746 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
748 * Added SilcKeyAgreementStatus type to the key agreement routines
749 to indicate the current status and error if one occured.
750 The status types are defined in the lib/silcclient/silcapi.h.
752 * Added new local command KEY that is used to set and unset private
753 keys for channels, set and unset private keys for private messages
754 with remote clients and to send key agreement requests and
755 negotiate the key agreement protocol with remote client. The
756 key agreement is supported only to negotiate private message keys,
757 it currently cannot be used to negotiate private keys for channels,
758 as it is not convenient for that purpose.
760 * Fixed a minor pending callback setting bug in the function
761 silc_client_get_client_by_id_resolve, now the function works.
762 Affected file lib/silcclient/idlist.c.
764 * Added function silc_net_get_local_port to get local bound
765 port by socket. Added to lib/silcutil/silcnet.[ch].
767 * Added `sockets' and `sockets_count' fields to the SilcClient
768 object. They hold the sockets of the listenning sockets in
769 the client. Listenning sockets may be for example the key
770 agreement server. Affected file lib/silcclient/client.[ch].
771 Added functions the silc_client_add_socket and the
772 silc_client_del_socket. They are exported to the application
775 * Added ~./silc/clientkeys to support other client's public keys.
777 * Renamed verify_server_key client operation to verify_public_key
778 and added one argument to indicate the type of the connection
779 (server, client etc.).
781 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
783 * Added silc_server_connection_auth_request to handle the
784 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
785 silcd/packet_receive.[ch].
787 * Added silc_server_send_connection_auth_request into the
788 silcd/packet_send.c to send the connection auth request packet.
790 * Cleaned up the silcd/protocol.c a bit and fixed some memory
793 * Fixed the public key authentication in responder side in the
794 server. The `auth_data' pointer includes the SilcPublicKey
795 not the path to the public key. Affected file silcd/protocol.c.
797 * Implemented the public key authentication in the initiator side
798 in the server. Affected file silcd/protocol.c.
800 * Removed the [RedirectClient] config section from the server
801 configuration. Is not needed and I don't want to implement it.
803 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
805 * Cleaned up the CMODE command in the server. It now works
806 correctly and supports all the modes defined in the protocol.
807 Affected file is silcd/command.c.
809 * Added `hmac_name' field to the SilcChannelEntry in the server
810 to hold the default HMAC of the channel. It can be set when
811 creating the channel (with JOIN command). Affected files
814 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
815 type to indicate the change of the current cipher and hmac
816 on the channel. Client can safely ignore the <cipher> argument
817 (if it chooses to do so) since the CHANNEL_KEY packet will
818 force the channel key change anyway. The <hmac> argument is
819 important since the client is responsible of setting the new
820 HMAC and the hmac key into use.
822 * Fixed the CMODE command in the client library as well.
824 * Tested CMODE command in router environment successfully.
826 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
828 * Show the version of the remote client (or server) when connecting
829 to the server. It is logged to the log file. Affected file
832 * Fixed the KILLED notify handling in the client library. The
833 client must be removed from all channels when receiving the
836 Also, do not remove the client entry when giving the KILL
837 command but when the KILLED notify is received.
839 * Removed silc_idlist_find_client_by_nickname from the server.
840 Not needed anymore. Affected files silcd/idlist.[ch].
842 * Implemented the CHANNEL_CHANGE notify type handling to the
843 server. Affected file silcd/server.c.
847 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
849 * Added silc_server_send_notify_invite to send the INVITE
850 notify between routers.
852 * Implemented the INVITE command correctly to the server.
854 * Implemented the INVITE notify type handling in the server.
856 * Implemented the INVITE command to the client library and on the
859 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
861 * Added function silc_server_get_client_resolve to find the
862 client entry by ID from all ID lists and then resolve it
863 (using WHOIS) if it cannot be found. Affected file is
866 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
868 * Implemented the BAN command to the client library.
870 * The JOIN command in the server now checks the invite list
873 * Changed the silc_command_reply_payload_encode_va and the
874 silc_command_payload_encode_va to support that if argument is
875 NULL it ignores and checks the next argument. Affected file
876 lib/silccore/silccommand.c.
878 * Added silc_server_send_notify_ban to send the BAN notify
879 type between routers.
881 * Chaned the silc_notify_payload_encode to support that if
882 argument is NULL it ignores and checks the next argument.
883 Affected file lib/silccore/silcnotify.c.
885 * Tested ban lists in router environment successfully.
887 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
889 * Implemented BAN command to the server, in silcd/command.[ch].
891 * Removed the BAN and INVITE_LIST modes from the CMODE command
894 * Added function silc_string_match to regex match two strings.
895 Affected files lib/silcutil/silcutil.[ch].
897 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
899 * Redefined parts of the SilcChannelEntry in the server to support
900 the new ban and invite lists.
902 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
904 * Redefined the INVITE command. The same command can be used to
905 invite individuals to the channel but also to manage the invite
906 list of the channel (to add to and remove from the invite list).
907 Updated the protocol specs.
909 * Added new command SILC_COMMAND_BAN that can be used to manage
910 the ban list of the channel. Updated the protocol specs.
912 * Removed the channel modes: the SILC_CMODE_BAN and the
913 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
914 in the CMODE command. The equivalent features are now available
915 using INVITE and BAN commands. Updated the protocol specs.
917 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
918 in the network about change in the current ban list. The notify
919 type is not used by the client.
921 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
922 support the invite lists.
924 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Added new function silc_string_regexify that converts string
927 including wildcard characters into regex string that can
928 be used by the GNU regex library. Added into the file
929 lib/silcutil/silcutil.[ch].
931 Added silc_string_regex_combine to combine to regex strings
932 into one so that they can be used as one regex string by
933 the GNU regex library. Added into the file
934 lib/silcutil/silcutil.[ch].
936 Added silc_string_regex_match to match two strings. It returns
937 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
939 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
941 * Imported GNU regex to the soruce tree into lib/contrib.
942 Fixed some compiler warning from the regex.c.
944 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
946 * Fixed MOTD command in the server to work in router environment.
948 * Fixed the MOTD command in the client library to support
949 the server argument in the command.
951 * Added `nickname_len' argument to the silc_idlist_add_client
952 in the server, as the `nickname' argument may be binary data
955 * Added silc_idlist_get_channels to return all channels from
958 * Implemented LIST command to the server. Affected file is
961 * Implemented the LIST command to the client library and on the
964 * Added [<user count>] argument to the LIST command reply.
965 With private channels the user count is not shown.
967 * Updated TODO and README.
969 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
971 * The client entry's data.registered must be TRUE even with
972 global client entry on global client list. The data.registered
973 is used to check whether the client is anymore in the network,
974 for example with WHOWAS command so it must be valid.
976 * Fixed the WHOWAS command in the server. It now actually works
977 in router environment. Added function into silcd/command_reply.c
978 silc_server_command_reply_whowas_save.
980 * Added silc_idlist_purge function to the silcd/idlist.c
981 to periodically purge the ID Cache.
983 * Fixed INFO command in the server. It works now in router
984 environment. Added <server name> argument to the INFO command
985 reply. Updated the protocol specs.
987 * Fixed minor bug in silc_idcache_purge to not purge if the
988 expire value is zero.
990 * Fixed various bugs in WHOIS and IDENTIFY command handling as
991 they were buggy because of the WHOWAS information.
993 * Fixed local command MSG to handle the async resolving of
994 the remote client properly. It used to fail the first MSG.
995 Affected file silc/local_command.c.
997 * Added `data_len' field to SilcIDCache context.
999 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1001 * Update TODO. Todo in commands in the server.
1003 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1005 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1006 used by routers as broadcast packet to inform other routers
1007 about the changed user mode.
1009 Implemented the notify handling in the server. Affected file is
1010 silcd/packet_receive.c. Added the function
1011 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1013 * Added new generic Channel Payload and deprecated the New Channel
1014 Payload. The New Channel Payload is now the generic Channel
1017 * Added new argument `mode' to the silc_server_send_new_channel
1018 as it is required in the Channel Payload now.
1020 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1021 and created a new and real SilChannelPayload to represent the
1022 new generic Channel Payload. Implemented the encode/decode
1023 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1025 * Added silc_server_get_client_channel_list to return the list
1026 of channels the client has joined for WHOIS command reply.
1027 Affected file silcd/server.[ch].
1029 * Implemented the channel list sending in the WHOIS command reply
1030 in server and in the client.
1032 Implemented the channel list displaying on the user interface
1033 as well. Affected file silc/client_ops.c.
1035 * Added silc_channel_payload_parse_list to parse list of Channel
1036 Payloads. It returns SilcDList list of SilcChannelPayloads.
1037 Client for example can use this function to parse the list of
1038 channels it receives in the WHOIS command reply. The caller
1039 must free the list by calling silc_channel_payload_list_free.
1040 Affected files lib/silccore/silcchannel.[ch].
1042 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1044 * Added one new argument <user mode> to the WHOIS command reply
1045 to return the mode of the user in SILC. Updated the protocol
1048 Implemented it to the server and client.
1050 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1052 * Fixed the mode printing on the user interface on joining.
1053 Affected file silc/client_ops.c.
1055 * Implemented the UMODE command and user modes in general to the
1056 client library and to the user interface.
1058 * Implemented the UMODE command to the server.
1060 * The server now sends UNKNOWN_COMMAND error status if client sends
1061 unknown command. Affected file silcd/command.c.
1063 * All server commands now handle the command identifier the right
1064 way when sending the command reply to the client. The client can
1065 use to identify the command replies with the identifier.
1067 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1069 * Added silc_server_get_client_route to resolve the route to
1070 the client indicated by the client ID. Affected file is
1073 * Added silc_server_relay_packet as general function to relay
1074 packet to arbitrary destination. This deprecates functions
1075 like _send_private_message_key, _relay_notify etc. Affected
1076 file is silcd/packet_send.[ch].
1078 Removed silc_server_send_key_agreement,
1079 silc_server_send_private_message_key and
1080 silc_server_packet_relay_notify functions from the file
1081 silcd/packet_send.[ch].
1085 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1086 server. Affected file silcd/packet_receive.[ch].
1088 * Implemented the KILL command to the client. Implemented the
1089 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1090 Affected files lib/silcclient/command[_reply].c and
1091 lib/silcclient/client_notify.c. Implemented the KILL notify
1092 printing in the user inteface.
1094 * Fixed a lot silc_parse_nick memory leaks from the client
1095 library in the file lib/silcclient/command.c.
1097 * Changed the silc_server_send_notify_on_channels's `sender'
1098 argument from SilcSocketConnection to SilcClientEntry to
1099 check the sender as entry and not as connection object and not
1100 to send to the client provided as argument. The affected file
1101 is silcd/packet_send.[ch].
1103 * The notify packets that are destined directly to the client used
1104 to not to be processed by the server. Now changed that and the
1105 server processes all notify packets. After relaying the packet
1106 to the client the notify packet is processed in the server.
1108 * The silc_server_free_client_data now checks whether there is
1109 pending outgoing traffic for the client and purges the data to
1110 the network before removing the client entry.
1112 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1114 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1115 an client is killed from the SILC Network. Updated the protocol
1118 Added new function silc_server_send_notify_killed to the
1119 silcd/packet_send.[ch].
1121 * Added function silc_server_packet_relay_notify to relay notify
1122 packets that are destined directly to a client. In this case
1123 the server does not process the notify packets but merely relays
1124 it to the client. Affected file silcd/packet_send.[ch].
1126 Added also silc_server_packet_process_relay_notify to check
1127 whereto relay the notify. Affected file is
1128 silcd/packet_receive.[ch].
1130 * Implemented the KILL command to the server.
1134 * Added the backup schema desgined last fall to the protocol
1135 specs for everyone to see. The specification is in the
1136 *-spec-xx.txt draft and the packet type definitions for the
1137 backup routers is in *-pp-xx.txt draft. Thusly, added also
1138 new packet type SILC_PACKET_CELL_ROUTERS.
1140 * A big security problem in the implementation discovered. The
1141 signoff of an client did not cause new channel key generation
1142 which it of course should've done. The channel keys must be
1143 always re-generated when client leaves (or signoffs) the channel.
1144 The silc_server_remove_from_channels funtion now handles
1145 the channel key re-generation.
1147 * Added `sender' argument to the silc_server_send_notify_on_channels
1148 to not to send the client provided as argument. Affected file
1149 silcd/packet_send.[ch].
1151 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1153 * Implemented OPER and SILCOPER commands into the server and
1156 * Added silc_auth_verify and silc_auth_verify_data to verify
1157 the authentication directly from the authentication payload.
1158 It supports verifying both passphrase and public key based
1159 authentication. Affected file lib/silccore/silcauth.[ch].
1161 * Added `hash' field to the SilcIDListData structure. It is the
1162 hash negotiated in the SKE protocol. Affected file is
1165 * Slight redesigning of the SilcAuthPayload handling routines.
1166 Do not send SilcPKCS but SilcPublicKey as argument.
1168 * Implemented the public key authentication support to the
1169 serverconfig. The public key is loaded from the provided path
1170 and saved as authentication data to void * pointer. Thus,
1171 changed the unsigned char *auth_data to void *auth_data;
1173 * Fixed SHUTDOWN command to send the reply before the server
1174 is shutdown. :) Affected file silcd/command.c.
1176 * Fixed fatal bug in CONNECT command. The hostname was invalid
1177 memory and server crashed. Affected file silcd/command.c.
1179 * Fixed fatal bug in CLOSE command. The server_entry became
1180 invalid but was referenced later in the command. Affected file
1183 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1185 * Fixed fatal bug in failure packet handling. Server ignored
1186 the failure and thus crashed when it came.
1190 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1192 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1193 that the command may be executed only once in (about) 2 seconds.
1194 The old SILC_CF_LAG flag is same but allows command bursts up
1195 to five before limiting.
1197 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1198 server code. Various commands now includes the CF_LAG_STRICT
1199 flag to disallow any kind of miss-use of the command.
1201 * Fixed the silc_buffer_unformat to not to allocate any data
1202 if the length of the data is zero. It used to allocate the
1203 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1205 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Changed the format of AdminConnection configuration section
1208 in the server. Added username of the admin to the format.
1209 Affected files silcd/serverconfig.[ch].
1211 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1212 to return admin configuration data by host, username and/or
1215 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1217 * Implemented WHOWAS command to the server. Added the functions:
1219 silc_server_command_whowas_parse,
1220 silc_server_command_whowas_send_reply,
1221 silc_server_command_whowas_from_client and
1222 silc_server_command_whowas_from_server
1224 * Added <Client ID> argument to the WHOWAS command reply. Updated
1225 the protocol specs accordingly.
1227 * Implemented WHOWAS command and command_reply to the client
1230 Implemented the WHOWAS printing on the user interface.
1232 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1234 * Added new argument to the WHOWAS command reply, the real name.
1235 It is an optional argument. Updated the protocol specs.
1237 * Added SilcIDCacheDestructor callback that is registered when
1238 the SilcIDCache is allocated. The callback is called when
1239 an cache entry in the ID Cache expires, or is purged from the
1240 cache. Added into lib/silccore/idcache.[ch].
1242 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1243 to destruct the client entries when the cache entry expires.
1244 Other ID Cache's in server and in the client library ignores
1247 * If the ID Cache entry's `expire' field is zero then the entry
1248 never expires. Added boolean `expire' argument to the
1249 silc_idcache_add function in the lib/silccore/idcache.[ch].
1250 If it is TRUE the default expiry value is used.
1252 * Added silc_server_free_client_data_timeout that is registered
1253 when client disconnects. By default for 5 minutes we preserve
1254 the client entry for history - for WHOWAS command.
1256 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1258 * Added support to the server to enforce that commands are not
1259 executed more than once in 2 seconds. If server receives
1260 commands from client more frequently, timeout is registered
1261 to process the commands. Affected file silcd/command.c.
1262 Added new function silc_server_command_process_timeout.
1264 * Changed NICK_NOTIFY handling in client library to check that
1265 if the client's nickname was changed, so there is no need to
1266 resolve anything from the server.
1268 * Removed error printing from the WHOIS and IDENTIFY commands.
1269 If error occurs then it is ignored silently in the client library.
1270 The application, however, may map the received error to
1271 human readable error string. The application currently maps
1272 the NO_SUCH_NICKNAME error to string.
1274 * Made the command status message public to the application. Moved
1275 them from lib/silcclient/command_reply.c to
1276 lib/silcclient/command_reply.h. The application can map the
1277 received command status to the string with the
1278 silc_client_command_status_message function.
1280 * Added check to the server to check that client's ID is same
1281 as the Source ID in the packet the client sent. They must
1284 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1286 * Added dist-bzip hook to the Makefile.am to make bzip2
1287 compressed distributions.
1289 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1291 * Server now enforces the maximum length for the nickname and
1292 the channel as protocol specification dictates. 128 bytes for
1293 nickname and 256 bytes for channel name.
1295 * Moved the WHOIS printing to the application. The client libary
1296 does not print out the WHOIS information anymore, the application
1297 must do it. Renamed silc_client_command_reply_whois_print to
1298 the silc_client_command_reply_whois_save.
1300 The client's idle time is also sent to the application now, and
1301 the idle is shown on screen.
1303 * Added silc_client_command_reply_identify_save to save the
1304 received IDENTIFY entries.
1306 * Do not check for channel private keys in message sending and
1307 reception if the channel does not have the PRIVKEY mode set.
1308 Affected file lib/silclient/client_channel.c.
1310 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1312 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1313 just surfaced after chaning the JOIN procedure.
1315 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1317 * Added silc_client_get_clients_by_list to get client entries
1318 from Client ID list, that is returned for example by JOIN
1319 and USERS command replies. The application should use this
1320 function for example when JOIN command reply is received to
1321 resolve the clients already on the channel (library does not
1322 do that anymore as USERS command reply is not used in the JOIN
1323 procedure anymore). Affected files lib/silcclient/silcapi.h and
1324 lib/silcclient/idlist.c.
1326 * JOIN command reply and USERS command reply returns now SilcBuffer
1327 pointers instead of unsigned char pointers when returning
1328 the client list and mode list.
1330 * Added <Client ID> argument to the JOIN command reply, mainly
1331 for the server to identify for which client the command was
1332 originally sent. Updated protocol specs accordingly.
1334 * Added SilcDlist private_key pointer to the SilcChannelEntry
1335 in the client to support the channel private keys. Affected
1336 file is lib/silcclient/idlist.h.
1338 * Added SilcChannelPrivateKey argument to the function
1339 silc_client_send_channel_message so that application can choose
1340 to use specific private ke if it wants to. If it is not provided,
1341 the normal channel key is used, unless private keys are set.
1342 In this case the first (key that was added first) is used
1343 as the encryption key.
1345 * Implemented the support for channel private key handling.
1346 Implemented the following functions:
1348 silc_client_add_channel_private_key,
1349 silc_client_del_channel_private_keys,
1350 silc_client_del_channel_private_key,
1351 silc_client_list_channel_private_keys and
1352 silc_client_free_channel_private_keys
1354 Affected file lib/silcclient/client_channel.c.
1356 * Added the support for the private keys in the channel message
1357 sending and encryption and in the message reception and
1358 decryption. Affected funtions are
1359 silc_client_send_channel_message and silc_client_channel_message.
1361 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Added SKE's key verify callback to the client library's
1364 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1366 * Removed the statement that server (or router) must send USERS
1367 command reply when joining to the channel so that the client
1368 knows who are on the channel. Instead, the client list and
1369 client's mode list is now sent in the JOIN command reply to the
1370 client who joined channel. This is better solution.
1372 * Added function silc_server_get_users_on_channel and function
1373 silc_server_save_users_on_channel to the silcd/server.[ch].
1375 * Removed function silc_server_command_send_users from the
1378 * Do not show topic on the client library anymore. The topic is
1379 sent in the command reply notify to the application and the
1380 application must show the topic now.
1382 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1384 * Added client searching by nickname hash into the IDENTIFY and
1385 WHOIS commands in the server as they were clearly missing from
1386 them. Affected file is silcd/command.c.
1388 * Fixed a bug in private message receiving in the client library.
1389 The remote ID was freed and it wasn't supposed, now it is
1392 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1394 * Minor fix to the channel payload; allocate the data area, as it
1395 needs to be of specific length.
1397 * If the key agreement port is zero then the operating
1398 system will define the bound port. Affected files are
1399 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1401 * Added new function silc_channel_payload_decrypt into the file
1402 lib/silccore/silcchannel.[ch].
1404 * Moved the channel message etc, check from silc_packet_decrypt
1405 to applications. The library calls now a generic
1406 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1407 when the packet is either normal or special. This was done to
1408 allow more wide range of checking that was not allowed when
1409 the code was in library. Now applications can do virtually any
1410 checks to the packet and return to the library the decision how
1411 the packet should be processed. Affected files are
1412 lib/silccore/silcpacket.[ch].
1414 Added silc_server_packet_decrypt_check to the server and
1415 silc_client_packet_decrypt_check to the client library.
1417 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1418 to send with specified source and destination information.
1420 * Channel message delivery between routers was broken after the
1421 channel key distribution was fixed earlier. The channel key
1422 was used be to distributed to other routers as well which is not
1423 allowed by the protocol. Now this is fixed and channel keys
1424 really are cell specific and the channel message delivery between
1425 routers comply with the protocol specification.
1427 * Fixed various commands in server to check also the global list
1428 for the channel entry and not just the local list. The affected
1429 file silcd/command.c.
1431 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1433 * Added assert()s to buffer formatting and unformatting routines
1434 to assert (if --enable-debug) when error occurs. Affected
1435 file: lib/silcutil/silcbuffmt.c.
1437 * Changed to auto-reconnect to check whether the remote host is
1438 router and register the re-connect timeout if it is. It used
1439 to check that whether we are normal server, but router must do
1440 auto-reconnect with another router as well. Affected file
1443 * Removed the [<key len>] option from CMODE command as the cipher
1444 name decides the key length, nowadays. See the defined ciphers
1445 from the protocol specification.
1447 * Added [<hmac>] option to the CMODE command to define the HMAC
1448 for the channel. Added SILC_CMODE_HMAC channel mode.
1450 * Added [<hmac>] option for the JOIN command so that user can
1451 select which HMAC is used to compute the MACs of the channel
1454 * Added Hmac field to the Channel Message Payload. The integrity
1455 of plaintext channel messages are now protected by computing
1456 MAC of the message and attaching the MAC to the payload. The
1457 MAC is encrypted. Now, it is clear that this causes some
1458 overhead to the size of the packet but rationale for this is that
1459 now the receiver can verify whether the channel message decrypted
1460 correctly and also when private keys are set for the channel the
1461 receiver can decrypt the packet with several keys and check from
1462 the MAC which key decrypted the message correctly.
1464 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1465 lib/silccrypt/silccipher.[ch].
1467 * Added silc_hash_len to return the digest length into the
1468 lib/silcrypt/silchash.[ch].
1470 * Rewrote parts of Silc Channel Payload interface in the
1471 lib/silccore/silcchannel.[ch]. The encode function now also
1472 encrypts the packet and parse function decrypts it.
1474 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1476 * Fixed a minor formatting bug in the SKE's key material processing.
1477 It actually might have processed the keys wrong way resulting
1480 * Redefined the mandatory HMAC algorithms and added new algorithms.
1481 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1482 and hmac-md5 truncated to 96 bits. The mandatory is now
1483 hmac-sha1-96. Rest are optional (including the one that used
1484 to be mandatory). Rationale for this is that the truncated HMAC
1485 length is sufficient from security point of view and can actually
1486 make the attack against the HMAC harder. Also, the truncated
1487 HMAC causes less overhead to the packets. See the RFC2104 for
1490 * Added new [hmac] configuration section. The SKE used to use
1491 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1492 is of course wrong. The official names that must be proposed in
1493 the SKE are the ones defined in the protocol specification
1494 (hmac-sha1-96 for example). The user can configure any hmac
1495 using any hash function configured in the [hash] section. At
1496 least, the mandatory must be configured.
1498 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1500 * Added HMAC list to the SKE proposal list. It has now both
1501 hash algorithm list and HMAC list. This makes the protocol
1502 incompatible with previous versions. The SKE now seems to work
1503 the way it is supposed to work, for the first time actually.
1505 * Defined plain Hash algorithms to the protocol specification.
1508 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * Implemented support for key agreement packets into the server.
1511 Added functions silc_server_key_agreement and
1512 silc_server_send_key_agreement. Other than these functions,
1513 server has nothing to do with this packet.
1515 * Added support for private message key packets into the server.
1516 Added functions silc_server_private_message_key and
1517 silc_server_send_private_message_key.
1521 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1522 called in the protocol's final callback instead in the END
1523 protocol state. This makes a little more sense and in the same
1524 time in client we can use the same protocol routines for normal
1525 key exchange and to key agreement packet handling as well.
1527 * Added to both client's and server's KE protocol context the
1528 SilcSKEKeyMaterial pointer to save the key material. We will
1529 bring the key material to the protocol's final callback by doing
1530 this. The final callback must free the key material.
1532 * Added SKE's packet_send callback into client's KE protocol
1533 context so that the caller can choose what packet sending function
1534 is used. This way we can use different packet sending when
1535 doing normal SKE when doing key agreement packet handling (in
1536 the key agreement packet handling we do not want to encrypt
1539 * Implemented the responder side of the key agreement routines
1540 in the client. The client can now bind to specified port and
1541 accept incoming key negotiation. The key material is passed
1542 to the application after the protocol is over.
1544 * Implemented the processing of incoming Key Agreement packet
1545 in the client. Added function silc_client_key_agreement to
1548 * Implemented the intiator side of the key agreement routines
1549 in the client. The client can now initiate key agreement with
1550 another remote client. The key material is passed to the
1551 application after the protocol is over.
1553 * Created client_keyagr.c to include all the key agreement
1556 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1557 SILC_TASK_CALLBACK except that it is not static.
1559 * Created client_notify.c and moved the Notify packet handling
1560 from the client.[ch] into that file.
1562 * Created client_prvmsg.c and moved all private message and
1563 private message key routines from the client.[ch] into that file.
1565 * Create client_channel.c and moved all channel message and
1566 channel private key routines from the client.[ch] into that file.
1568 * Changed silc_client_get_client_by_id_resolve to resolve with
1569 WHOIS command instead of IDENTIFY command, in the file
1570 lib/silclient/idlist.c.
1572 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * Implemented the SKE's responder side to the Client library.
1576 * When FAILURE is received to the protocol do not trust it
1577 blindly. Register a timeout to wait whether the remote closes
1578 the connection as it should do it, only after that process the
1579 actual failure. This was changed to both client and server.
1581 * Added client_internal.h to include some of the structures
1582 there instead of client.h in lib/silcclient/.
1584 * Added function silc_task_unregister_by_callback to unregister
1585 timeouts by the callback function.
1587 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1589 * Some "Incomplete WHOIS info" errors has been appearing on the
1590 log files. Took away the entry->userinfo check from WHOIS
1591 reply sending. The entry->userinfo is now " " if client did not
1592 provide one. I thought this was fixed earlier but something
1593 is wrong still. Let's see if the error still appears.
1595 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1597 * Fixed a minor bug in the login when the channel key is
1598 re-generated in the server. It used to generate the key in
1599 wrong order and thus caused problems in the channel traffic.
1601 * Fixed a minor bug in channel key distsribution after
1602 KICK command. The key was not sent to the router even though
1605 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1607 * Added silc_ske_process_key_material_data as generic routine
1608 to process any key material as the SILC protocol dictates. The
1609 function is used by the actual SKE library but can be used by
1610 applications as well. This relates to the private message keys
1611 and the channel private keys since they must be processed the
1612 same way the normal SILC session keys. The protocol dictates
1613 this. Affected files: lib/silcske/silcske.[ch].
1615 Added also silc_ske_free_key_material to free the
1616 SilcSKEKeyMaterial structure.
1618 * Defined silc_cipher_set_key function to set the key for
1619 cipher without using the object's method function. The affected
1620 files: lib/silccrypt/silccipher.[ch].
1622 * Implemented silc silc_client_add_private_message_key,
1623 silc_client_add_private_message_key_ske,
1624 silc_client_del_private_message_key,
1625 silc_client_list_private_message_keys and
1626 silc_client_free_private_message_keys functions in the
1629 Added functions silc_client_send_private_message_key to send
1630 the Private Message Key payload and silc_client_private_message_key
1631 to handle incoming Private Message Key payload.
1633 * Added Cipher field to the Private Message Key payload to set
1634 the cipher to be used. If ignored, the default cipher defined
1635 in the SILC protocol (aes-256-cbc) is used.
1637 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1639 * Removed lib/silcclient/ops.h file.
1641 Redefined parts of the SILC Client Library API. Created new
1642 file silcapi.h that deprecates the ops.h file and defines the
1643 published Client Library API. Defined also private message key
1644 API and channel private key API into the file.
1646 This is the file that the application must include from the
1647 SILC Client Library. Other files need not be included by
1648 the application anymore.
1650 * Added new key_agreement client operation callback and also
1651 defined the Key Agreement library API for the application.
1653 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1656 is used by clients to request key negotiation between another
1657 client in the SILC network. If the negotiation is started it
1658 is performed using the SKE protocol. The result of the
1659 negotiation, the secret key material, can be used for example
1660 as private message key.
1662 Implemented the Key Agreement payload into the files
1663 lib/silccore/silauth.[ch].
1665 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1667 * Redefined ciphers for the SILC protocol. Added some new ciphers
1668 and defined the key lengths for the algorithms. Changed the
1669 code accordingly. The default key length is now 256 bits.
1671 * Fixed SKE key distribution function silc_ske_process_key_material
1672 when the key length is more than 128 bits. The default key
1673 length in SILC is now 256 bits.
1675 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1676 to indicate unsupported algorithm.
1678 * Renamed rijndael.c to aes.c and all functions as well.
1680 * Fixed a long standing channel key setting bug in client library.
1681 Weird that it has never surfaced before.
1683 * Fixed bug in channel deletion. If the entire channel is removed
1684 then it must also delete the references of the channel entry
1685 from the client's channel list as the client's channel entry and
1686 the channel's client entry share same memory.
1688 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1690 * Implemented CONNECT and SHUTDOWN commands in the client.
1692 * Implemented CLOSE command to the client.
1694 * Added the function silc_idlist_find_server_by_name into the
1695 files silcd/idlist.[ch].
1697 Added the function silc_idlist_find_server_by_conn into the
1698 files silcd/idlist.[ch].
1700 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1702 * DIE command was renamed to SHUTDOWN. Updated the both code
1705 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1706 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1708 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1711 * Added function silc_server_create_connection function to create
1712 connection to remote router. My server implementation actually
1713 does not allow router to connect to normal server (it expects
1714 that normal server always initiates the connection to the router)
1715 so the CONNECT command is only good for connecting to another
1718 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1721 or some other client was kicked from the channel.
1723 Implemented the handling of the notify type to both client
1726 Implemented silc_server_send_notify_kicked to send the KICKED
1727 notify. It is used to send it to the server's primary router.
1729 * Implemented the KICK command into server and client.
1731 * Added `query' argument to the silc_idlist_get_client function
1732 to indicate whether to query the client from server or not if
1735 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1736 to indicate that the client is not channel founder.
1740 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1742 * Removed the rng context from SilcPacketContext structure and
1743 changed that the packet routine uses the Global RNG API.
1745 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1747 * Added support for quit message that client can "leave" on the
1748 channel when it quits the SILC. It is ditributed inside the
1749 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1751 Added silc_server_free_client_data that will take the
1752 signoff message as argument.
1754 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1756 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1758 * Updated parts of the protocol specification to keep it up
1761 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1763 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1764 payloads in one packet.
1766 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1767 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1768 use now the new List flag.
1770 * Also deprecated the following packet types: REPLACE_ID,
1771 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1773 * Added list support for Notify packet in server.
1775 * Added silc_server_send_notify_channel_change to send the
1776 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1777 the silc_server_send_replace_id.
1779 * Added silc_server_send_notify_nick_change to send the
1780 NICK_CHANGE notify type. Deprecates the function
1781 silc_server_send_replace_id.
1783 * Added silc_server_send_notify_join to send the JOIN notify type.
1784 Deprecates the function silc_server_send_new_channel_user.
1786 * Added silc_server_send_notify_leave to send LEAVE notify type.
1787 Deprecates the function silc_server_send_remove_channel_user.
1789 * Added silc_server_send_notify_cmode and
1790 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1791 types. Deprecates the silc_server_send_set_mode function.
1793 * Added SERVER_SIGNOFF notify type to indicate that server has
1794 quit. This means that all clients on the channel from that
1795 server will drop. This can be also used when netsplit happens.
1797 Deprecated REMOVE_ID packet type since it is not needed anymore
1800 Added silc_server_send_notify_server_signoff to send the
1801 SERVER_SIGNOFF notify type. Deprecates the function
1802 silc_server_send_remove_id.
1804 Added also silc_server_send_notify_signoff to send the
1805 SIGNOFF notify type.
1807 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1808 SILC protocol from this day on. Changed the protocol
1809 specification as well.
1811 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1812 notify type. It is used between routers to notify about
1813 topic changes on a channel.
1815 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1818 * Partly updated the protocol specification to comply with the
1819 changes now made. It is still though a bit outdated.
1821 * The JOIN notify type now takes one extra argument <Channel ID>.
1822 The packet used to be destined to the channel but now the
1823 JOIN type may be sent as list thus it is impossible to
1824 destine it to any specific channel. By adding this argument
1825 it is again possible.
1827 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1829 * Added CREDITS file. The CHANGES and CREDITS file will appear
1830 in the distribution as well.
1832 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1834 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1835 types in the server's silcd/packet_receive.c.
1837 * Implemented CMODE and CUMODE to work in router environment.
1839 * Fixed minor encoding and decoding buglet from the
1840 lib/silccore/silcmode.c.
1842 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1845 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1847 * Changed all SilcConfigServer* and silc_config_server* to
1848 SilcServerConfig* and silc_server_config*, respectively.
1851 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1853 * Associated the ID (client or server ID) to the Authentication
1854 Payload to avoid any possibility of forging. Updated the
1855 protocol specification and the code accordingly.
1857 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * The RSA key length is now save to the RsaKey context in the
1860 key generation process in lib/silccrypt/rsa.c. The key length
1861 is now used to figure out the maximum size of the block allowed
1862 to be encrypted/signed.
1864 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1865 is equivalent to the silc_mp_mp2bin but does not allocate any
1868 * Changed silc_mp_mp2bin API to take length argument. If it is
1869 non-zero then the buffer is allocated that large. If zero, then
1870 the size is approximated using silc_mp_sizeinbase, which however
1873 * Created Global RNG API which is global RNG that application can
1874 initialize. After initializing, any routine anywhere in the
1875 code (including library) can use RNG without allocating a new
1876 RNG object. This was done to allow this sort of use of the
1877 RNG in code that has no chance to allocate RNG object. All
1878 applications currently allocate this and many routines in the
1879 library use this. Affected file lib/silccrypt/silcrng.[ch].
1881 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1882 it to use the Global RNG API.
1884 * Defined Authentication Payload into protocol specification that
1885 is used during SILC session to authenticate entities. It is
1886 used for example by client to authenticate itself to the server
1887 to obtain server operator privileges.
1889 Implemented this payload into the lib/silccore/silcauth.[ch].
1890 Implemented also routines for public key based authentication
1891 as the new protocol specification dictates.
1893 Moved definitions of different authentication methods from
1894 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1896 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1897 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1898 silc_pkcs_verify_with_hash functions into the file
1899 lib/silccrypt/silcpkcs.[ch].
1901 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * The client entry's userinfo pointer must be always valid.
1904 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1905 will fail since it requires the userinfo. Now, the userinfo
1906 is allocated as "" if actual userinfo does not exist. Actually,
1907 it must exist and it is totally Ok to drop client connections
1908 that does not announce the userinfo. However, we will make
1909 this workaround for now.
1911 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1912 to return the remote port by socket.
1914 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1917 SILC_SERVER_PENDING_EXEC and added an new macro
1918 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1919 data or when error occurs while processing the pending command.
1921 Added new argument `destructor' into silc_server_command_pending
1922 and to the SilcServerCommandPending object. This destructor is
1923 now called after calling the pending callback or if error occurs
1924 immediately. If error occurs the actual pending callback won't
1925 be called at all - only the destructor. The destructor may be
1926 NULL if destructor is not needed.
1928 All this applies for client library code as well. Similar
1929 changes were made there as well for the pending commands.
1931 In the client, the application must now allocate the
1932 SilcClientCommandContext with the silc_client_command_alloc
1935 * Added reference counter to the SilcServerCommandContext. Added
1936 function silc_server_command_alloc and silc_server_command_dup
1939 Same type of functions added to the client library for the same
1942 * Removed the cmd_ident from IDListData away since it is now
1943 global for all connections. It is the command identifier used
1944 in command sending and with pending commands. The affected file
1947 * Added reference counter to the SilcSocketConnection objecet to
1948 indicate the usage count of the object. The object won't be
1949 freed untill the reference counter hits zero. Currently only
1950 server uses this, and client ignores it. The client must be
1951 set to use this too later. The affected files are
1952 lib/silccore/silcsockconn.[ch]. Added also the function
1953 silc_socket_dup to increase the reference counter.
1955 This was mainly added because it is possible that the socket
1956 is removed underneath of pending command or other async
1957 operation. Now it won't be free'd and proper DISCONNECTING
1958 flags, etc. can be set to avoid sending data to connection that
1959 is not valid anymore.
1961 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1962 the connection. After that it sets SILC_SET_DISCONNECTED.
1963 It is, however, possible that the socket data is not still freed.
1964 The silc_server_packet_process now checks that data is not
1965 read or written to connection that is DISCONNECTED. The socket
1966 get's freed when the reference counter hits zero.
1968 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1970 * Changed the client operation API: channel_message operation's
1971 `sender' is now the client entry of the sender, not the nickname
1972 and the `channel' is the channel entry, not the channel name.
1974 In the private_message operation the `sender' is now also the
1975 client entry of the sender not the nickname.
1977 Affected file is lib/silcclient/ops.h and all applications
1978 using the client operations.
1980 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1982 * Moved the calling of ops->connect() from connect_to_server_final
1983 into receive_new_id functin since that is the point when the
1984 client is actually allowed to send traffic to network. The
1985 affected file is lib/silcclient/client.c.
1987 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1989 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1990 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1991 (if needs broadcasting) instead of broadcasting the packets one
1992 by one which would make a burst in the network traffic.
1994 * Added `broadcast' argument to the functions in silcd/server.[ch]
1995 silc_server_create_new_channel[_with_id] to indicate whether
1996 to send New Channel packet to primary router.
1998 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2000 * Added new function into the silcd/server.[ch] files:
2001 silc_server_create_new_channel_with_id to create new channel with
2002 already existing Channel ID.
2004 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2005 lib/silccore/silcpacket.h. This packet is used t send list of
2006 Set Mode payloads inside one packet. Server uses this to set
2007 the modes for the channels and clients on those channels, that it
2008 announced to the router when it connected to it. The protocol
2009 specification has been updated accordingly.
2011 * The silc_server_new_channel did not handle the packet coming
2012 from normal server as it normally does not send that. However,
2013 when it announces its channels it does send it. Implemented
2014 the support for that.
2016 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2017 into the file lib/silccore/id.h.
2019 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2021 * Fixed memory leaks in the functions silc_idlist_del_client,
2022 silc_idlist_del_channel and silc_idlist_del_server in the file
2023 silcd/idlist.c. All of those leaked like a sieve.
2025 * Fixed some small memory leaks in the client's function
2026 silc_client_notify_by_server.
2028 * Added functions into silcd/server.c: silc_server_announce_clients,
2029 silc_server_announce_channels and silc_server_announce_server.
2030 These functions are used by normal and router server to announce
2031 to its primary router about clients, channels and servers (when
2032 router) that we own. This is done after we've connected to the
2035 These functions effectively implements the following packet types:
2036 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2037 and SILC_PACKET_NEW_ID_LIST.
2039 * Added new functions into the silcd/packet_receive.[ch]:
2040 silc_server_new_id_list, silc_server_new_channel_list and
2041 silc_server_new_channel_user_list to handle the incoming
2042 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2044 * Added support of changing Channel ID in the function
2045 silc_server_replace_id. If the server that announces a channel
2046 to the router already exists in the router (with same name but
2047 with different Channel ID), router is responsible to send
2048 Replace ID packet to the server and force the server to change
2049 the Channel ID to the one router has.
2051 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2052 client that the Channel ID has been changed by the router. The
2053 normal server sends this to the client. Client must start using
2054 the new Channel ID as the channel's ID.
2056 Implemented handling of this new type into lib/silcclient/client.c
2057 into the function silc_client_notify_by_server.
2059 * Added new function silc_idlist_replace_channel_id into the files
2060 silcd/idlist.[ch] to replace the Channel ID.
2062 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Call silc_server_command_identify_check always when processing
2065 the IDENTIFY command in silcd/command.c
2067 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2069 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2070 send keepalive packets. The packet can be sent by clients,
2071 servers and routers.
2073 Added function silc_socket_set_heartbeat into the file
2074 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2075 If not set, the heartbeat is not performed. The actual
2076 heartbeat is implemented in the low level socket connection
2077 library. However, application is responsible of actually
2080 Added silc_server_send_heartbeat to send the actual heartbeat
2081 packet into silcd/packet_send.[ch]. Server now performs
2082 keepalive with all connections.
2084 * Added silc_task_get_first function into lib/silcutil/silctask.c
2085 to return the timeout task with shortest timeout. There was a bug
2086 in task unregistration that caused problems. TODO has been
2087 updated to include that task system must be rewritten.
2089 * The client library will now resolve the client information when
2090 receiving JOIN notify from server for client that we know but
2091 have incomplete information.
2093 * Rewrote parts of silc_server_remove_from_channels and
2094 silc_server_remove_from_one_channel as they did not remove the
2095 channel in some circumstances even though they should've.
2097 * Encryption problem encountered in server:
2099 The LEAVE command used to send the Channel Key packet to the
2100 router immediately after generating it. However, the code
2101 had earlier sent Remove Channel user packet but not immediately,
2102 ie. it was put to queue. The order of packets in the router
2103 was that Channel Key packet was first and Remove Channel User
2104 packet was second, even though they were encrypted in the
2105 reverse order. For this reason, MAC check failed. Now, this
2106 is fixed by not sending the Channel Key packet immediately but
2107 putting it to queue. However, this is more fundamental problem:
2108 packets that are in queue should actually not be encrypted
2109 because packets that are sent immediately gets encrypted
2110 actually with wrong IV (and thus MAC check fails). So, packets
2111 that are in queue should be encrypted when they are sent to
2112 the wire and not when they put to the queue.
2114 However, the problem is that the current system has not been
2115 designed to work that way. Instead, the packet is encrypted
2116 as soon as possible and left to the queue. The queue is then
2117 just purged into wire. There won't be any fixes for this
2118 any time soon. So, the current semantic for packet sending
2121 o If you send packet to remote host and do not force the send
2122 (the packet will be in queue) then all subsequent packets to the
2123 same remote host must also be put to the queue. Only after the
2124 queue has been purged is it safe again to force the packet
2127 o If you send all packets immediately then it safe to send
2128 any of subsequent packets through the queue, however, after
2129 the first packet is put to queue then any subsequent packets
2130 must also be put to the queue.
2132 Follow these rules and everything works fine.
2134 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2136 * Added new function silc_server_remove_clients_by_server to
2137 remove all client entries from ID list when the server connection
2138 is lost. In this case it is also important to invalidate all
2139 client entires as they hold the invalid server entry. This
2140 fixes fatal bug when server has lost connection and will reconnect
2143 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2145 * Made some sanity checks to silc_server_daemonise like to check
2146 whether the requested user and group actually exists.
2148 * Added sanity check to SKE's silc_ske_responder_finish to check
2149 that the public and private key actually is valid.
2151 * Invalidate the client's nickname when receiving Replace ID
2152 packet and the Client ID is being replaced. This means that the
2153 server will query the nickname if someone needs it (client)
2156 * Sort the ID Cache in client library when the ID Cache data
2157 has changed (needs sorting).
2159 * Do not allow for SILC client to create several connections to
2160 several servers. The client does not support windows right now
2161 and generating multiple connections causes weird behaviour.
2163 Irssi-silc client does support windows and can handle several
2164 connections without problems, see: www.irssi.org and SILC plugin.
2166 * Fixed some places where client was added to the IDList. The
2167 rule of thumb is following (in order to get everything right):
2168 If the client is directly connected local client then the
2169 `connection' argument must be set and `router' argument must be
2170 NULL to silc_idlist_add_client function. If the client is not
2171 directly connected client then the `router' argument must
2172 bet set and the `connection' argument must be NULL to the
2173 silc_idlist_add_client function.
2175 * The funtion silc_server_packet_send_local_channel actually did
2176 not check whether the client was locally connected or not. It
2177 does that now. Fixed a bug related to LEAVE command.
2179 * Fixed Remove Channel User payload parsing bug in server's
2180 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2182 * The server's silc_server_save_channel_key now checks also the
2183 global ID list for the channel as it might not be in the local
2184 list. Fixed a bug related to LEAVE command.
2186 * Is this the end of the [<unknown>] buglet that has been lurking
2187 around for a long time? A little for loop fix in server's
2188 silc_server_command_whois_parse that is used by both IDENTIFY
2189 and WHOIS command. At least, this was a clear bug and a cause
2190 of one type of [<unknown>] buglet.
2192 * WHOIS and IDENTIFY commands call the function
2193 silc_server_command_[whois/identify]_check function even if
2194 we are not router server.
2196 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2198 * Added --with-gmp configuration option. If set the GMP
2199 is always compiled in the SILC source tree. If not set then
2200 it is checked whether the system has the GMP3 installed. If
2201 it has then the GMP won't be compiled (the system's headers
2202 and library is used), if it doesn't have it then the GMP is
2203 compiled in the SILC source tree.
2205 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2207 * Changed RSA private exponent generation to what PKCS #1
2208 suggests. We try to find the smallest possible d by doing
2209 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2210 not security fix but optimization.
2212 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2214 * Added new config entry [Identity] to fork the server and run
2215 it as specific user and group. A patch from Bostik.
2217 * Imported Dotconf configuration library into lib/dotconf.
2218 This will be used to create the SILC configuration files later.
2219 It will appear in the distsribution after this commit.
2221 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2223 * A big code auditing weekend happening. Auditing code for
2224 obvious mistakes, bugs and errors. Also, removing any code
2227 Removed files for being obsolete:
2229 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2230 inline in the file lib/silcutil/silcbuffer.h)
2232 o lib/silcutil/silcbufutil.c (the header has inline versions)
2234 Changed code to fix possible error conditions:
2236 o The buffer formatting routines now check that the destination
2237 buffer really has enough space to add the data. This applies for
2238 both buffer formatting and unformatting
2239 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2240 unformatting was changed to accomodate following rules:
2241 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2242 sent to the function while XXX_*STRING will not allocate or copy
2243 the data into the buffer. Instead it sets the pointer from the
2244 buffer into the pointer sent as argument (XXX_*STRING used to
2245 require that the pointer must be allocated already). This change
2246 makes this whole thing a bit more consistent and more optimized
2247 (note that the data returned in the unformatting with XXX_*STRING
2248 must not be freed now). The routines return now -1 on error.
2250 o Tried to find all code that use buffer_format and buffer_unformat
2251 and added return value checking to prevent formatting and
2252 especially unformatting errors and possible subsequent fatal
2255 o Changed ske->x and ske->KEY to mallocated pointers in
2256 lib/silcske/silcske.h. Fixed possible data and memory leak.
2258 o Added return value checking to all *_parse* functions. Fixed
2259 many memory leaks as well.
2261 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2262 so that buffer overflows would not happen. All code now also
2263 checks the return value as it can fail.
2265 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2267 * Added reconnection support to server if the normal server looses
2268 its connection to the router (for example if router is rebooted).
2269 The server performs normal reconnection strategy implemented
2270 to the server. Affected file silcd/server.c.
2272 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2274 * Added new packet type SILC_PACKET_SET_MODE that is used to
2275 distribute the information about changed modes (for clients,
2276 channels and clients channel modes) to all routers in the
2277 network. Updated the protocol specification accordingly.
2279 Added functions into silcd/packet_send.c and
2280 silcd/packet_receive.c: silc_server_send_set_mode,
2281 silc_server_set_mode.
2283 Added new files silcmode.[ch] into lib/silccore that implements
2284 the encoding and decoding of Set Mode Payload. Added new type
2285 SilcSetModePayload. Moved the definitions of different modes
2286 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2288 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2290 * Oops, a little mistake in server's connection authentication
2291 protocol. The protocol is not ended with FAILURE but with
2292 SUCCESS if the authentication is Ok. :) Affected file is
2295 * Implemented NICK_CHANGE notify handling in server in the file
2296 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2297 the local clients on the channel. After the changing nickname
2298 in router environment snhould work and the [<unknown>] nickname
2299 should appear no more.
2301 The silc_server_replace_id function that receives the Replace ID
2302 payload now sends the NICK_CHANGE notify type also in the file
2303 silcd/packet_receive.c
2305 * Changed WHOIS and IDENTIFY command to support the maximum amount
2306 of arguments defined in protocol specs (3328 arguments). This
2307 fixed a bug that caused problems when there were more than three
2310 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2312 * Added extra parameter, command identifier, to the
2313 silc_client_send_command so that explicit command identifier
2316 Changed that ID list routines uses specific command identifier
2317 when sending WHOIS/IDENTIFY requests to the server so that they
2318 can be identified when the reply comes back.
2320 Affected files lib/silcclient/command.[ch],
2321 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2323 * Added `sender' argument to silc_server_packet_send_to_channel
2324 to indicaet the sender who originally sent the packet to us
2325 that we are now re-sending. Ignored if NULL. Affected file
2326 silcd/packet_send.[ch].
2328 * Added some server statistics support in silcd/server_internal.h
2329 SilcServerStatistics structure and around the server code. Also
2330 send some nice statistics information when client is connecting
2333 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2335 * Fixed channel ID decoding in server's JOIN command reply in
2336 silcd/command_reply.c
2338 * Fixed braodcasting of replace ID payload to not to send it if
2339 we are standalone server in silcd/packet_receive.c.
2341 * Fixed all channel message sending routines to not to send
2342 packets to clients that has router set, since they are routed
2343 separately in the same function earlier. Affects file
2344 silcd/packet_send.c and all channel packet sending functions.
2346 * In USERS reply, res_argv[i] are not allocated, the table
2347 is allocated. Thus changed that free the table, not its
2350 * In server's whois_check and identify_check if the client is
2351 locally connected do not send any WHOIS commands - they are not
2354 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2356 * Fixed some minor bugs in client when sending WHOIS command. The
2357 arguments was in wrong order.
2359 * Removed statis function add_to_channel from server in
2360 silcd/command.c that was previously used with the joining but
2363 * Tested USERS command in router environment successfully with two
2364 routers, two servers and two clients.
2366 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2368 * Reorganized the USERS command and command reply in client library
2369 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2370 When the command is given by user we register a pending command
2371 callback that will reprocess the command after the reply has been
2372 received from the server. When reprocessing the packet we then
2373 display the information. Thus, the USERS information is displayed
2374 now in the command callback instead of in the command reply
2375 callback. The processing of the command is same as previously
2376 when server has sent the command reply in the JOINing process.
2378 * Added to USERS command in silcd/command_reply.c to join the client,
2379 we didn't use to know about, to the channel after we've created
2380 a client entry for it. Also, for clienet we did know already still
2381 check whether it is on the channel or not and add it if not.
2383 * Removed silc_server_command_join_notify as the function and its
2386 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2388 * Changed the client's pending command handling to the same as the
2389 server's pending command handling. It is also now possible to
2390 execute command reply functions from other command reply
2391 function as the function callbacks for commands and command
2392 replies are one and same. The pending commands are not static
2393 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2394 in client connection context. Thus, pending commands are server
2395 connection specific as it is convenient.
2397 Changed the function silc_client_command_pending and
2398 silc_client_command_pending_del and added new function
2399 silc_client_command_pending_check. Removed the
2400 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2403 * Added cmd_ident, current command identifier, to the client
2404 connection context in lib/silcclient/client.h to keep track on
2405 command identifiers used in command sending. Client's command reply
2406 function handling now supports the mandatory command identifiers.
2408 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2409 funtions in client to fully support pending command callbacks.
2411 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2412 as one of the arguments to the application in the command reply
2415 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2416 before first releasing SILC but came back. Now it is removed again
2417 and should come back nomore. The FORWARDED flag was used only
2418 by the JOINing procedure by forwarding the command packet to router.
2419 Now, the JOINing procedure has been changed to more generic (due
2420 to various router environment issues) and FORWARDED is not needed
2421 anymore for anything. The protocol specification is yet to be
2424 Now, removed silc_server_packet_forward from server and the flag
2425 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2427 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2429 * Renamed NAMES command to USERS command. The NAMES was named that
2430 due to historical reasons. Now it is renamed. Also, rewrote
2431 parts of the USERS command. The nickname list is not sent anymore
2432 by the server. Only Client ID and mode lists are sent in the USERS
2433 command. Changed this also to the protocol specification.
2435 The client now resolves the names and stuff after it receives
2436 the USERS list from the server when joining to the channel.
2438 * WHOIS and IDENTIFY commands has been changed to support multiple
2439 Client ID's per command. One can now search for multiple users
2440 in the network by sending only one WHOIS or IDENTIFY command.
2441 Changed the code and the protocol specifications.
2443 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2444 uses silc_server_command_whois_parse to parse the request. */
2446 * If normal server, do not parse the WHOIS and IDENTIFY requests
2447 before sending it to the router. Saves some time.
2449 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2451 * Fixed JOIN command on client library. Wrong number of arguments
2452 used to crash the client.
2454 * Added silc_server_channel_has_global function to check whether
2455 channel has global users or not.
2457 * Added silc_server_channel_has_local function to check whether channel
2458 has locally connected clients on the channel.
2460 * The silc_server_remove_from_one_channel now checks whether the
2461 channel has global users or not after given client was removed from
2462 the channel. It also checks whether the channel has local clients
2463 on the channel anymore. If it does not have then the channel entry
2464 is removed as it is not needed anymore.
2466 * The silc_server_notify now checks on JOIN notify whether the joining
2467 client is one of locally connected or global. If it is global then
2468 the channel has now global users on the channel and that is marked
2469 to the channel entry. Also, it now saves the global client to
2470 global list who is joining and JOINs it to the channel. This is
2471 for normal server, that is.
2473 Changed silc_server_send_notify_on_channel,
2474 silc_server_packet_relay_to_channel and
2475 silc_server_packet_send_to_channel check if we are normal server
2476 and client has router set (ie. global client) do not send the
2477 message to that client, as it is already routed to our router.
2479 * Implemented LEAVE notify type handling in silc_server_notify
2482 * Tested LEAVE command in router environment successfully. Tested
2483 with two routers, two servers and two clients.
2487 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2489 * Implemented SIGNOFF notify type handling in silc_server_notify
2492 * silc_server_remove_id now removes the client entry from all channels
2493 it has joined and thusly sends SIGNOFF notify type.
2495 * Rewrote the NAMES list generation in server by removing two excess
2496 loops. The lists are created now inside one loop.
2498 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2500 * silc_server_remove_channel_user checks now also global list
2501 for channel and client.
2503 * silc_server_new_channel_user checks now both local and global
2504 list for channel and client. Fixed a bug in client id decoding.
2505 Used to decode wrong buffer.
2507 * silc_server_channel_message checks now both local and global
2508 list for channel entry.
2510 * Tested channel joining (hence JOIN) in router environment
2511 successfully. Tested with two routers, two servers and two
2514 * Tested channel message sending in router environment successfully.
2516 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2518 * Added silc_server_save_channel_key into server.[ch] to save the
2519 received channel key in Channel Key payload processing. It is
2520 also used in JOIN command reply handling.
2522 Equivalent function silc_client_save_channel_key added into
2523 client.[ch] into client library.
2525 * Changed JOIN command reply to send information whether the channel
2526 was created or not (is existing already) and the channel key
2527 payload. Changed protocol specs accordingly.
2529 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2530 the request was sent by ID and not by nickname. Crashed on
2533 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2535 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2536 now correctly save the received data.
2538 * silc_server_free_sock_user_data now notifies routers in the
2539 network about entities leaving the network.
2541 At the same time implemented functions silc_server_remove_id
2542 and silc_server_send_remove_id to receive and send REMOVE_ID
2543 packets. The packet is used to notify routers in the network
2544 about leaving entities. The ID removed will become invalid in
2547 * Added function silc_idlist_del_server into server. Removes and
2548 free's server entry from ID list.
2550 * silc_server_private_message function now checks, if we are router,
2551 that the destination ID really is valid ID, naturally.
2553 * In router when NEW_ID packet is received (for new client) the
2554 hash of the Client ID is saved in the ID Cache but the
2555 client->nickname is set to NULL, instead of putting the hash
2558 IDENTIFY command now also checks that client->nickname must be
2559 valid. If it is not if will request the data from the server who
2560 owns the client. Added new function
2561 silc_server_command_identify_check.
2563 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2564 to set the command to already allocated Command Payload.
2566 * Tested private message sending in router environment with two
2567 routers, two servers and two clients. Fixed minor bugs and now
2570 * Fixed segfault from client's NAMES command. Used to crash if
2573 * Forwarded packets must not be routed even if it is not destined
2574 to the receiver. Changed server code comply with this.
2576 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2578 * Added `require_reverse_mapping' boolean value to ServerParams
2579 structure. If TRUE (not default) the server will require that
2580 the connecting host has fully qualified domain name.
2582 If the reverse mapping is not required and hostname could not be
2583 found the IP address is used as hostname.
2585 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2587 * Implemented version string checking to both client and server.
2588 The check is incomplete currently due to the abnormal version
2589 strings used in development version of SILC.
2591 * Changed all command functions in server to use the new
2594 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Changed char *data to unsigned char *data in ID Cache system to
2597 support binary data as ID Cache data. Changed code to support
2598 binary data in lib/silccore/idcache.c.
2600 * Renamed silc_server_packet_relay_command_reply to
2601 silc_server_command_reply as it is normal packet receiving
2602 function. Rewrote the function to accept command replys for
2603 servers and not only for clients.
2605 * Mark remote router always as registered server if we are connecting
2606 to it. Otherwise, commands sent by the router to us are ignored.
2608 * All ID List find routines now returns the ID Cache Entry pointer
2609 as well if requested.
2611 * WHOIS command works now in router environment, tested with two
2612 routers, two servers and two clients.
2614 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2615 in router environment (as it is almost equivalent to WHOIS) but
2616 hasn't been tested thoroughly. Added new functions:
2618 silc_server_command_identify_parse
2619 silc_server_command_identify_send_reply
2620 silc_server_command_identify_from_client
2621 silc_server_command_identify_from_server
2623 * Disabled route cache adding because adding two different ID's with
2624 same IP replaces the old cache entry thus giving wrong route.
2625 The entry->router->connection is always the fastest route anyway
2626 so route cache may not be needed. Of course, new routes maybe
2627 established after receiving the ID when the entry->router->connection
2628 might not be anymore the most optimal.
2630 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2632 * Add route cache for received ID for fast routing.
2634 * Added silc_server_packet_route to route received packet on router
2635 that is not destined to us.
2637 * Renamed silc_server_get_route to silc_server_route_get.
2639 * Added id_string and id_string_len fields into SilcServer to
2640 include encoded ServerID for fast comparing without excess
2641 encoding of the ID's.
2643 * Cleaned up WHOIS command on server side. Added following static
2646 silc_server_command_whois_parse
2647 silc_server_command_whois_check
2648 silc_server_command_whois_send_reply
2649 silc_server_command_whois_from_client
2650 silc_server_command_whois_from_server
2652 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2653 arguments in command replies. All command functions should be
2654 updated to use this macro.
2656 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Minor typo fixes on command reply handling on server.
2660 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2662 * Added silc_server_command_add_to_channel internal routine to add
2663 the client to the channel after router has created the channel and
2664 sent command reply to the server.
2666 * Added generic silc_server_send_command to send any command from
2669 * Use static buffer with ID rendering instead of duplicating data.
2671 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2673 * Fixed a channel user mode bug when joining to a channel server gave
2674 everybody channel founder rights, oops.
2676 * We mark ourselves as the router of the incoming server connection
2677 if we are router ourselves. This way we can check in some packet
2678 sending functions whether it is locally connected server. For
2679 incoming router connections we put NULL.
2681 * For router sending packets locally means now always sending the
2682 packet cell wide; to local clients and local servers. For normal
2683 server sending packet locally means sending it to only local
2686 * Fixed the JOIN command to really work in router environment. If the
2687 channel is created it is always created by the router. Router is
2688 also responsible of making the initial joining to the channel,
2689 sending JOIN notify to the sending server and distributing
2690 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2691 does not exist server doesn't do anything else but forward the
2692 command to the router which performs everything.
2694 * Added silc_server_send_channel_key function to send the Channel Key
2697 * Added silc_server_create_channel_key to create new channel key. The
2698 channel key is now re-generated everytime someone joins or leaves
2699 a channel, as protocol dictates. Note: channel->key_len is the
2702 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2704 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2705 packet_receive.[ch] to separate packet sending and receiving
2706 routines. The server.[ch] now includes everything else including
2707 actual packet processing (writing and reading data) and other
2710 Renamed silc_server_private_message_send_internal to
2711 silc_server_send_private_message. The routine is still though
2712 used only to relay private messages as server does not send
2713 private messages itself.
2715 Renamed silc_server_new_channel to silc_server_create_new_channel
2716 and added new function sicl_server_new_channel that handles the
2717 incoming New Channel packet. Added also new sending function
2718 silc_server_send_new_channel to send New Channel Payload.
2720 * Added new function silc_server_notify to process incoming notify
2721 packet to the server/router. Server may then relay the notify
2722 to clients if needed.
2724 * Added new function silc_server_new_channel_user to process incoming
2725 New Channel User packet. Router will redistribute the packet and
2726 send JOIN notify to its local clients and locally connected servers
2727 if needed. Normal server will send JOIN notify to its local client
2728 on same channel when received this packet. Added also corresponding
2729 sending function silc_server_send_new_channel_user to sent the
2732 * Added boolean route argument to send_notif_to_channel and
2733 packet_send_to_channel functions to attempt to route the packet
2734 if it is TRUE and send only locally if it is FALSE.
2736 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2738 * silc_server_replace_id now broadcasts the received replace ID
2739 packet if it is not broadcast packet already. The router must
2740 broadcast to inform other routers about changed ID.
2742 * Added backpointer to server's router into SilcServer context in
2743 silcd/server_internal.h.
2745 * Fixed silc_server_packet_broadcast to send correct broadcast
2748 * The channel key is now distributed to the local client as soon
2749 as it is received from the router (in router environment) so that
2750 no other packet may be sent for the channel until client has
2753 * silc_server_remove_channel_user now broadcasts the received
2754 Remove Channel User packet if it is not broadcast packet already.
2755 The router must broadcast to inform other routers about removed
2758 * Added users field into SilcPacketContext that is a reference count
2759 of the context. One can increase the reference count by calling
2760 silc_packet_context_dup which is now changed to just increase the
2761 reference count instead of duplicating the data. The reference
2762 count is decresed by calling silc_packet_context_free that will
2763 free the data after the reference count hits zero.
2765 For now on the packet context and everything allocated into it
2766 (including the raw packet from network) must be freed by calling
2767 the new silc_packet_context_free function. Added also new function
2768 silc_packet_context_alloc that must be used now to allocate the
2769 context. This also means that if a routine is asynchronous from
2770 silc_[client/server]_packet_parse_type the packet context must
2771 be duplicated by calling silc_packet_context_dup. Otherwise it
2772 gets free'd after silc_[client/server]_packet_parse_type returns.
2773 Also, one must remember that if packet is duplicated then its
2774 reference count must be decresed by calling the free function as
2775 many times as it was duplicated.
2777 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2778 from both client and server.
2780 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2782 * Made joining to a channel working in router environment.
2784 * Cleaned up JOIN command on server side and create function
2785 silc_server_command_join_channel internal routine to make the
2788 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2790 * Changed silc_command_pending list to SilcDList. Also, added
2791 `ident' field to SilcServerCommandPending structure to identify
2792 the reply and to call correct callback.
2794 Added silc_server_command_pending_check function to replace the
2795 corresnponding macro. The silc_command_pending list is not
2798 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2799 to set identifier to previously allocated Command Payload. It
2800 is used to set identifier for command when resending Command
2803 * Added silc_command_payload_encode_payload to encode Command
2804 Payload buffer from SilcCommandPayload structure.
2806 * Added silc_argument_payload_encode_payload to encode Argument
2807 payload buffer from SilcArgumentPayload structure.
2809 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Changed WHOIS command to support router connection on server side.
2812 The whois request is always sent to router unless the server is
2813 standalone server. After server has received the reply from the
2814 router will it send the reply to the client.
2816 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2817 broadcast received broadcast packet. The function is used only
2818 by router. The broadcast packet is always sent to the router's
2821 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2822 render given ID to printable string, for log files for example.
2824 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2826 * Made basic router to router connections working. At least they
2827 can now connect to each other but nothing really works the way
2828 they are supposed - yet.
2830 * Added new initiator token to RouterConnection configuration
2831 file in silcd/serverconfig.[ch]. It is used to tell whether we
2832 are the initiator to the remote router or whether we'll expect
2833 the other end to connect.
2835 * Moved registering of listener task to silc_server_init, hence
2836 the server starts listenning as soon as it is run, even if it
2837 does not have connections to other routers. Let's see how well
2840 * Changed default connection retry timeouts for more suitable in
2843 * Removed cipher and such arguments from silc_idlist_add_client
2844 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2845 Added new function silc_idlist_add_data to add the keys and stuff
2848 * Added SilcIDListData structure and added it to SilcClientEntry
2849 and SilcServerEntry as their first field in the structure. This
2850 way we can explicitly cast the ID entries to the SilcIDListData
2851 structure and get common data for the entries. In past, we had
2852 to first check what type of connection it is and then cast it to
2853 correct ID entry type. Now, we can directly cast the opaque
2854 pointer to the SilcIDListData (no matter what ID entry it actually
2855 is) and get the data needed.
2857 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2860 in some circumstances even if threre were timeout tasks, though not
2861 IO tasks, but tasks anyway. Now fixed.
2863 * Defined SilcServerConnection structure to hold connection specific
2864 stuff about directly connected servers and routers. The definition
2865 is currently in silcd/server_internal.h. I thought about having
2866 a bit more important role fro this struct but for now it is used
2867 only when connecting to other server (or router actually).
2869 * Added connecting retry support in server when connecting to
2870 router(s). The retry feature implement exponential backoff
2871 algorithm. Also, added SilcServerParams structure to hold default
2872 parameters for server. For now, it include these retry settings
2873 and are hard coded. After server is moded to be as Silc Server
2874 Library this structure will be more important.
2876 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Changed client librarys channel->clients table to SilcList and
2879 changed code accordingly.
2881 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2883 * Changed client's channel table to SilcList and changed code
2884 accordingly. Also changed SilcChannelClientEntry to include back-
2885 pointer to the channel so that client entry can use that structure
2886 as list as well and we have fast cross-reference to the channel.
2887 This change dramatically decreased the complexity of channel
2888 handling with client entry and vice versa (removed one extra
2889 loop when searching for channel entry from many functions).
2891 * Changed server->sim from table to SilcDList and changed code
2894 * NAMES command can now be used from user interface. It will show
2895 the user list on the channel, neatly.
2897 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2898 Code now saves realname of the user if it becomes available.
2900 * Renamed configure.in to configure.in.pre and made ./prepare
2901 script to automatically add correct version string to
2902 configure.in which it creates from configure.in.pre.
2904 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2906 * NAMES command reply now shows users mode with the nickname when
2909 * Moved silc_client_ch[u]mode[_char] functions from
2910 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2911 place sucks, they are utility functions and should be in some
2914 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2916 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2919 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2923 * Added TRQ (efficient deque and list library) into lib/trq. This is
2924 a very good list library that is currently used in the SILC. Defined
2925 SilcList API over the library because I didn't like the API very
2926 much. See lib/trq/silclist.h for the API and examples of how to
2927 use the API. Fixed various places in the code to use the new
2928 SilcList API. The SilcList is meant for lists that has a structure
2929 already defined as a list. It is not suitable to add just some
2930 context to the list (in TRQ, the context is the list actually).
2932 So, I defined SilcDList that can be used for the purpose where
2933 predefined list structure does not exit. This can be used as
2934 such list. Now some context just can be added to the SilcDList.
2935 Currently this list is not used in the SILC just yet, though there
2936 are a lot places where this can replace dynamically allocated
2937 tables and I will fix these places, later, to use SilcDList.
2938 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2939 and use TRQ internally).
2941 Also fixed some annoying warning messages that the original TRQ
2942 code generated. Also minor changes to TRQ's Makefile.in.
2944 * Added support for querying by Client ID to both WHOIS and
2945 IDENTIFY commands into server, as required by the protocol.
2947 * Removed method function pointers from SilcBuffer structure. They
2948 weren't used to anything and just increased the context size for
2949 no good reason. This change also made silc_buffer_alloc and
2950 silc_buffer_free functions inline functions.
2952 * Disabled command flooding detection support until it's fixed so
2953 that it accepts commands in but does not execute them more than once
2956 * Added silc_net_localhost(), to return local hostname, into
2957 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2958 that must be initialized before calling silc_client_init.
2960 * Added new function: silc_server_send_notify_on_channels to send
2961 notify messages to all channels client has joined. It is assured
2962 that the message is sent only once per client.
2964 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2965 lib/silcutil/silcutil.[ch] as silc_format function. The new
2966 function is generic and is used by server as well, not only by
2967 the logging routines.
2969 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2970 the provided version string was not acceptable. Added new function:
2971 silc_ske_check_version into lib/silcske/silcske.h. The function
2972 must be implemented by the application (client or server) and it
2973 does not reside in the SKE library. The function checks the version
2974 string remote end sent.
2976 * Added back pointers (to opaque context and to SilcSocketConnection)
2977 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2979 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2980 duplicate packet context structure.
2982 * Changed `notify' client operation to send same arguments as client
2983 receives from server except for ID's. ID's are mapped to correct
2984 ID entry and that is returned. Also, if channel entry is not sent
2985 by server but the notify is for channel the channel entry is sent
2986 to application (otherwise application doesn't know that it is for
2987 channel (library gets it from packet's Destination ID)).
2989 * Added silc_client_remove_from_channels into client library to
2990 remove a client from all channels it has joined to. Used when
2991 received SIGNOFF notify from server. Added also new function
2992 silc_client_replace_from_channels to replace old ID entry with
2993 new ID entry on all channels. Used when received NICK_CHANGE
2996 * Fixed ID Cache list handling in silc_idlist_get_client in
2997 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2998 to get (or query) client by ID.
3000 * Updated TODO list.
3002 * Added connection authentication status message defined by the
3003 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3004 support for these into the code in client and server side.
3006 * Added generic function silc_client_send_command to send any command
3007 with variable argument list. Application should use this function
3008 to send commands if the command functions provided by the library
3009 does not suite for the application's user interface needs.
3011 * Added new `failure' client operation. Application is notified about
3012 received failure packet if client is executing a protocol. In this
3013 case the protocol's execution has failed.
3015 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3016 is required by the protocol.
3018 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3019 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3022 * Added status flag to SilcSKE object to indicate realtime status
3023 of the SKE protocol.
3025 * Application receives now exactly same command reply arguments as
3026 the library receives from server. However, if ID is received the
3027 corresponding ID entry is returned to the application (eg. Client
3028 ID is mapped to correct SilcClientEntry entry and that is returned).
3029 Changed command_reply client operation due to this change.
3031 * Changed all ID's in commands and in command replys as ID Payloads.
3032 Change affected both client and server side codes.
3034 All ID's sent in SILC network (with execption of ID's in SILC
3035 Packet header) are sent in ID Payload to support variable length
3038 * Server now notifies nick changes and notifies all clients on
3039 the channels about the new nickname (about the new Client ID,
3042 * Implemented CMODE command to change channel modes. Supports all
3043 channel modes defined by the protocol specs except ban and invite
3044 lists. (Also, private channel key mode is supported but support for
3045 setting private channel key in client is missing, thus, this mode
3046 has no effect on client side (except that server requires that the
3047 client uses private channel key and normal channel traffic does not
3050 Also, invite mode works per se, but INVITE command does not work
3051 yet correctly, so you can set channel as invite only channel but
3052 inviting clients to the channel does not work (it is yet to be
3053 thought what's the best way to do it).
3055 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3056 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3057 Implemented CUMODE command to change user's mode on the channel.
3058 Supports all modes defined by the protocol specs.
3060 * Added NAMES command reply to return users modes on the channel.
3062 * Removed unnecessary and slow ciphers from lib/silccrypt.
3064 * Set SO_KEEPALIVE option to connection sockets by default.
3066 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3068 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3069 redefined the Notify Payload into protocol specs.
3071 * Added silc_id_payload_parse_id to get ID directly from raw
3074 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3076 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3077 accept searching by Client ID as well.
3079 * Added support for LEAVE and SIGNOFF notify types in client library.
3081 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3082 to parse ID Payload from raw data.
3084 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Added flags parameter into silc_ske_assemble_security_properties
3087 function in lib/silcske/silcske.[ch].
3089 * Changed notify client operation to fit better for notify messages
3090 sent by server. The notify payload received from server is now
3091 passed to the application (after parsing it to SilcNotifyPayload).
3092 It is application's responsibility to retrieve the arguments
3093 from the payload and show the message the way it wants. The message
3094 sent by server is implementation specific.
3096 * Changed public keys to comply with the protocol specification.
3097 Old public keys are not supported anymore and are not compatible.
3099 * Removed nickname from Channel Payload as the latest draft removed
3100 it. The client must resolve the nickname from the NAMES command
3101 reply received when it joined the channel.
3103 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3105 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Fixed some errors in protocol specification drafts.
3109 * Created lib/silccore/silcnotify.c to implement Notify Payload
3110 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3111 generic payloads described by protocol specifications. The file
3112 includes implementations for ID Payload and Argument Payload.
3114 * Changed Command Payload implementation to use the new Argument
3115 Payload. Changed command_xxxx_payload to command_payload_xxxx
3116 to comply with SILC coding conventions.
3118 * Added suppport for Argument Payload handling in Notify Payload
3119 implementation as protocol requires it. Added the new support
3120 into server and client lib as well.
3122 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Added support for multiple nicknames on same channel. [n] is
3125 added locally to the nickname if there are more than one same
3126 nicknames on the channel.
3128 * Server now sends all nicknames that matched WHOIS request.
3129 Client also shows the list received from server.
3131 * Added TOPIC command to client side. User can now set and show
3132 current topic on channel.
3134 * Added MOTD command to client and server. Also, server sends the
3135 motd when client connects to the server.
3137 * Changed version strings to comply ISO 8601.
3139 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3141 * Fixed protocol error handling in client library. It should now
3142 cope even if the SKE fails for some reason.
3144 * Made new protocol specification drafts for submitting to IETF.
3146 * Implemented TOPIC command to server in silcd/command.c.
3148 * Added two new notify types into lib/silccore/silcnotify.h:
3149 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3150 notify nickname change and topic setting/change on a channel.
3152 * API change of command_reply operation in client library. The
3153 application gets now the status type received from server as well.
3155 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3159 * Cras fixed and optimized the packet handling even further and
3160 it should work now. Minor change to the prototype of function
3161 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3163 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3165 * Added new function into lib/silcutil/silcschedule.[ch]:
3166 silc_schedule_with_fd to select() a specified fd. The function
3167 returns after timeout expires or data arrives or goes. The
3168 function is used by packet routines to wait that all data is
3169 received from network.
3171 * Fixed data reading from network in lib/silccore/silcpacket.c.
3172 The code now assures that all data is read from the fd and then
3173 continues packet processing. This was a bug fix since the code
3174 used to drop some data in some circumstances.
3176 * Added new function into lib/silcclient/client.[ch]:
3177 silc_client_start_key_exchange to start key exchange after
3178 connection has been established to server. The code internally
3179 now uses this funtion but its main purpose was to provide it
3180 for applications that perform their own connecting. After
3181 application has created a connection it merely calls this
3182 function to start the key exchange between client and server.
3183 The library takes care of everything else after that.
3185 Updated also lib/silcclient/README to explain the usage of
3188 * Do not send to application information that connection has
3189 been established. Application gets notified it by connect
3192 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Applied cras's patch to add silc_schedule_one function. The
3195 function runs scheduler once and returns.
3197 * Fixed the scheduler after cras messed it up. The timeout
3198 handling works now as it's supposed to work.
3200 * Added into lib/silccore/ silcnotify.h to include notify
3201 message types support. Changed silc_server_send_notify*
3202 functions, in server.[ch], to support those new notify types.
3203 Added the support for the notify types into client library,
3204 as well. Added new notify client operation into ops.h in
3207 * Changed silc_server_packet_send_to_channel to send normal
3208 packets instead of just channel message packets. The function
3209 is now used to send the notify packets to channels. It is not
3210 used to send channel message packets anymore, as server never
3213 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3214 va_arg()s as it seems to require it nowadays. I guess, if SILC
3215 is compiled with older va_arg() the new code should work anyway.
3217 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Splitted core library. Core library (lib/silccore) includes
3220 now only SILC protocol specific core (and common) components.
3221 Created new utility library (lib/silcutil) that includes more
3222 generic purpose stuff. The stuff for util library was taken
3223 from the old core library. This was minor and easy split.
3225 * Created SILC Client Library (lib/silcclient) that includes
3226 implementation of the SILC client without user interface. This
3227 was major move from silc/ directory. The code has been changed
3228 so that it is transparent towards the user interface. The
3229 silc/ directory includes now the same user interface as before
3230 and it uses the new client library. Read lib/silcclient/README.
3231 Basicly, the client library performs everything else related
3232 to SILC except user interface handling. Also, configuration
3233 files are considered to be part of user interface and library
3234 does not handle them.
3236 This change also changed a lot of structures, function naming etc.
3237 Most important change was that SilcClientWindow object was
3238 renamed to SilcClientConnection in the client library. Created
3239 also new file lib/silcclient/ops.h. Also added new files
3240 silc/local_command.[ch] and silc/client_ops.[ch].
3242 All these changes were made to make it easier for user interface
3243 designers to create what ever user interface for the SILC client
3246 It is also expected that the server will be moved to lib
3247 directory as well and SILC Server Library will be created;
3248 sometimes in the future.
3250 * Removed Local commands from lib/silccore/silccommand.h as
3251 they are application specific and new client library does not
3252 handle any of those anymore.
3254 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3255 old client implementation in silc/.
3257 * Added support for callback functions in SILC_LOG_* macros.
3258 Application can now set its own callbacks that will be called
3259 instead of using the default functions that will always print
3260 the debug messages to stderr (or stdout). Also, debugging can
3261 now be disabled by setting silc_debug to FALSE and re-enabled by
3262 setting it to TRUE. Note, that logging will still work even
3263 if debugging is disabled.
3265 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3266 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3267 silc_log_reset_debug_callbacks.
3269 * To enable debugging in silc client one must give now -d
3270 option on command line.
3272 * Changed silc_schedule_init to automatically allocate task queues
3273 if they are not allocated before calling it.
3275 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3277 * Added GMP 3.1 into math library.
3279 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3282 a channel in SILC network. The packet is used by servers and
3283 routers to notify other routers that user has left a channel.
3284 This little feature was missing until now. Added the feature
3285 to protocol specification as well.
3287 Added functions: silc_server_send_remove_channel_user and
3288 silc_server_remove_channel_user into server.[ch].
3290 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3291 lib/silccore/silcpacket.h. However, they are not implemented
3294 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3296 * Fixed joining to a channel and sending channel messages
3297 between server and router. The channel message sending should
3298 now work inside a cell.
3300 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Fixed the private message sending between server and router.
3303 The private message sending should now work inside a cell.
3305 * Added silc_server_replace_id into server.[ch] to replace
3306 existing ID in the SILC network.
3308 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3309 and silc_idlist_replace_server_id into idlist.[ch] in server.
3311 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3313 * Fixed the server to server connections. Server can again now
3314 connect to router. Router to router connections probably does
3317 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Added dynamic protocol registering support. Now protocols can
3320 registered and unregistered on the fly. Patch by cras.
3322 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3324 * Added lib/contrib directory to hold routines that some platforms
3325 don't have but are needed by SILC.
3327 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3328 into lin/contrib to provide getopt() and getopt_long() for
3329 those who don't have it.
3331 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Added AWAY command to client. When away message is set and
3334 client receives a private message packet the client automatically
3335 replies to the sender with the away message.
3337 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3338 bug seemed to be the cause of recent problems when compiling
3341 * Added version detection support to SKE protocol specification
3342 and added the new changes to the SKE implementation as well.
3343 There were other minor changes in the SKE protocol as well.
3345 Many changes in lib/silcske/silcske.[ch] and in
3346 lib/silcske/payload.[ch].
3348 * Added ^U functionality, clear input line. Patch from cras.
3350 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3352 * Mainly small bugfixes on core library. Fixed some debugging
3353 logging and buffer overflow in silclog.c.
3355 * Updated config.sub and config.guess on the distribution tree.
3357 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Added command lagging support in server. Client may execute
3360 commands now only once in two seconds.
3362 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Optimized packet reception. MAC computation and checking is now
3365 also more optimized. A lot previously duplicated code is now
3366 used as generic by both client and server.
3368 * Fixed key pair generation in clientutil.c
3370 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * Added into lib/silccore/silcbufutil.[ch] new function;
3373 silc_buffer_realloc.
3375 * Moved generic packet sending/encryption functions to
3376 lib/silccore/silcpacket.[ch] from client and server. Some
3377 rewriting of the functions.
3379 * Moved all generic packet reception/decryption functions to
3380 lib/silccore/silcpacket.[ch] from client and server. The
3381 packet processing is now much cleaner in both client and server.
3382 These were major changes in both client and server.
3384 * Created many common functions in server to do packet sending.
3385 Previously code were duplicated a lot, this has been removed
3388 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Rewrote major parts of the ID cache system. Don't know
3391 whether it is better now or not but at least the API is more
3394 * Major rewrite on ID cache stuff on client because of the ID
3395 cache API changes. Added idlist.c to client.
3397 * Also major rewrite on ID cache stuff on server as well.
3398 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3399 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3400 in hand, instead they are all put into the ID cache system now.
3401 All server_idlist_* routines uses ID cache now instead of
3402 traversing its own lists (those lists does not exist anymore).
3403 SilcIDList though still exists. Also, SilcXXXEntry's are
3406 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3408 * Finally made the SKE implementation compliant to the protocol
3409 specification. All mp integers are now binary encoded as
3410 opposed being HEX encoded.
3412 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3415 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3416 functions: silc_[encode/decode]_pem. Also added function
3417 silc_encode_pem_file to PEM encode with newlines ('\n') for
3420 * SILC public keys are now encoded either PEM or binary. Same
3421 option is for private keys as well. By default private keys
3422 are binary encoded and public keys PEM encoded. Silly HEX
3423 encoding were removed.
3425 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3426 function to create fingerprints.
3428 * Fixed a bug in SHA1; does not change the original data anymore.
3430 * Partly implemented INFO command on client and server side.
3431 Fixed CLEAR command. Changes to SERVER command; show current
3432 server(s) when giving command without arguments. Added
3433 VERSION command to client.
3435 * Added check to server that unregistered connections cannot
3436 execute commands (unless it is specificly allowed).
3438 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Fixed screen refresh.
3442 * Fixed channel joining bug from client. On some circumstances
3443 client tried to join to a channel it had already joined.
3445 * Added public key verification process into client's protocol.c.
3446 The client now verifies the public key from user and saves
3447 it into ~./silc/serverkeys/ directory.
3449 Added into: clientutil.[ch]: silc_client_verify_server_key.
3451 * Changed SKE protocol's silc_ske_initiator_finish function
3452 to accept callback function that verifies the received public
3453 key. Removed old silc_ske_verify_public_key function.
3455 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3458 silc_pkcs_private_key[_data]_set.
3460 * Made the password and public authentication more cleaner in
3461 server's protocol.c.
3463 * Removed historic and obsolete protocol `channel_auth' from
3464 both client and server.
3466 * Removed wrong way of sending command status messages from
3467 server to client in server's command.c. The old way violated
3468 protocol specification.
3470 Changes to silccore/silccommand.[ch]: removed
3471 silc_command_encode_status_payload -> not needed anymore,
3472 changed silc_command_encode_payload_va to accept extra
3473 argument on variable argument list. The argument type must
3474 now be provided to the function. Also, added new function:
3475 silc_command_encode_reply_payload_va which is same as
3476 normal command_encode_payload_va except command status type
3477 is provided as extra argument.
3479 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Added ~./silc directory handling. The directory includes the
3482 public and private keys for the client.
3484 Added silc_client_check_silc_dir, silc_client_create_identifier
3485 and silc_client_load_keys.
3487 * Implemented SILC protocol compliant public key. Added public
3488 and private key saving to and loading from files.
3490 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3491 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3492 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3493 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3494 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3496 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3497 silc_pkcs_load_[public/private]_key.
3499 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Added silc_server_get_route (route.[ch]) to get connection
3502 data for the fastest route for given ID.
3504 * Implemented INVITE command on client and server. The command
3505 were re-defined in the SILC Protocol Specification and the
3506 implementation now complies with the specification.
3508 * Implemented PING command on client and server.
3510 * Implemented NAMES command on client and server. The server side
3511 supports currently only normal server not router server yet.
3512 Some changes to NAMES definition in SILC protocol specification.
3514 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3516 * Implemented LEAVE command on client and server.
3518 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3519 again. This change was made to the protocol as well. Server
3520 should not violate the protocol specification anymore.
3522 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3525 was tested. SOCKS4 was not but should work anyway.
