1 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed memory leak in silc_encode_pem_file in the file
4 lib/silcutil/silcutil.c.
6 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Check minor version as well in the SKE. Affected files are
9 silcd/protocol.c and lib/silcclient/protocol.c.
11 * Added --identifier option to the server so that an identifier
12 can be when creating the public key for the server. Affected
13 file is silcd/silcd.c.
15 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
16 lib/silccrypt/silcpkcs.c.
18 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
20 * Register default ciphers and stuff when using -C option with
21 the server. Affected file sildc/silcd.c.
23 * Put back the servers public key filename format, it is better
24 than the new one. For now, the client keys are saved with the
25 new filename format. The affected file silc/client_ops.c.
27 * Implemented the Cipher API for the rest of the ciphers that
28 did not implement it or implemented it the wrong way.
30 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
32 * Register default ciphers and stuff when using the -S option
33 in the client. Affected file silc/silc.c. Same also when
34 creating new key pair with -C option.
36 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
38 * Fixed the silc_verify_public_key client operation function to
39 save the public keys differently. The fingerprint is now
40 used as filename and not the hostname. This way also the
41 client keys are saved uniquely and not with hostnames. The
42 affected file is silc/client_ops.c.
44 * Trimmed the silc_hash_fingerprint function to remove extra
45 whitespaces from the end of the fingerprint. The affected
46 file is lib/silccrypt/silchash.c.
50 * Added silc_cipher_register_default function to register all
51 default ciphers. It can be used when configuration files
52 does not exist and the application does not want any specific
53 ciphers in any specific order.
55 The SilcDList is now used as silc_cipher_list dynamically
56 allocated cipher list. Removed the static list all together
57 and now all ciphers must be allocated to the dynamic list.
58 The silc_cipher_alloc routine was changed to check only the
61 All silc_cipher_* routines that used to return int returns
64 The affected files lib/silccrypt/silccrypt.[ch].
66 * The same thing was done to silc_hash_* as for silc_cipher_*
67 routines. Affected files lib/silccrypt/silchash.[ch].
69 * The same thing was done to silc_pkcs_* as for silc_cipher_*
70 routines. Affected files lib/silccrypt/silcpkcs.[ch].
71 Added also silc_pkcs_[un]register[_default] functions.
72 Removed the data_context from the PKCS API.
74 * Added silc_hmac_register_default function to register default
75 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
76 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
77 to unregister all hmacs at once.
79 * Register the default ciphers, hash functions, PKCSs and HMACs
80 if client's configuration file does not exist. The affected
83 * The client did not load the hash functions from the SIM
84 modules at all. Added support for this. Affected file is
87 * When decoding public key with silc_pkcs_public_key_decode, check
88 the supported algorithm only if PKCS are registered. Affected
89 file lib/silccrypt/silcpkcs.c. The same was done with the
90 silc_pkcs_private_key_decode.
92 * Fixed the SILC List routines to keep the list always in order.
93 It used to change the list's order when traversing the list but
94 not it preserves the order. Affected file lib/trq/silclist.h.
96 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * Added the client library to use the SilcSocketConnection's
99 reference counter (by silc_socket_dup) to prevent the bug that
100 the socket object may be freed underneath async operation.
102 * The name resolv library checking fixes in the configure.in.pre.
105 * Created new version of the protocol drafts for future
106 development. The -03 drafts are the ones that will be changed
107 in the trunk now and the -02 will remain as they are.
109 * Send list of CUMODE notifys to the router when announcing
110 the channel users to the router. Affected file silcd/server.c.
111 If the router receiving channel founder CUMODE for a channel
112 that already has channel founder it will send CUMODE notify
113 to the sender to remove the channel founder rights from the
114 announced client. Affected file silcd/packet_receive.c.
116 * The CUMODE notify may now use Server ID as well as the entity
117 who changes the mode. Updated protocool specs.
119 * Updated INSTALL and README files.
121 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
123 * New web pages in the http://silc.pspt.fi. The pages was
128 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
130 * Implemented the [DenyConnectin] config section in the server.
131 Added silc_server_config_denied_conn to check whether incoming
132 connection is denied. Affected file silcd/serverconfig.[ch].
134 * Do not check the ports when checking the incoming configuration
135 data if the port is 0, meaning any. Affected file is
136 silcd/serverconfig.c.
138 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
140 * Fixed buffer overflow in silc_string_compare in the file
141 lib/silcutil/silcutil.c.
143 * Fixed double free in silc_server_command_leave in the file
146 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Fixed the version checking in the server. Affected file is
151 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
153 * Fixed the configuration data fetching when accepting new
154 connections in the server. Affected file silcd/server.c.
156 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
158 * Added `sender_entry' argument to the function
159 silc_server_packet_relay_to_channel so that we can check
160 whether some destination actually belongs to the same route
161 the sender belongs (ie, we must not resend the packet to the
162 sender). Affected file silcd/packet_send.[ch].
164 * Added `servername' field to the SilcClientEntry in the server
165 to hold the name of the server where client is from. Affected
166 file is silcd/idlist.h.
168 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
170 * Moved the channel message encrypting in the router betwen
171 router connections from silc_server_channel_message to the
172 silc_server_packet_relay_to_channel since we want to check
173 whether we have anybody channel before encrypting anything.
174 Affected files silcd/packet_[receive/send].c.
176 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
178 * Fixed the [AdminConnection] server config section to support
179 multiple entries. Affected file silcd/serverconfig.c.
181 * Added support into the server to check the validity of the
182 incoming connection before executing any KE or authentication
185 * The connection configuration is now saved to the KE and
186 connection auth protocol contexts and not fetched anymore in
187 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
189 * The local hosts listenning address and port is also resolved
190 now when starting the server. We want to have the socket object
191 to include the real address and port for the listener. Added
192 new function silc_net_check_local_by_sock into the files
193 lib/silcutil/silcnet.[ch].
195 * Fixed a broadcast bug in server -> do not broadcast if we
198 * Fixed a routing bug. Do not route broadcast packets ever.
199 Broadcast packets must be processed always and not routed since
200 they may be destined to some other host than yourself and thus
201 would get routed without no good reason. Affected file is
204 * Added function silc_server_config_is_primary_route to check
205 whether primary router connection has been configured (a router
206 configuration that we are initiating). If there is not, we
207 will assume that there is only two routers in the SILC network
208 and we will use the incoming router connection as our primary
209 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
211 * Changed the order of the broadcasting. Broadcast _after_ the
212 packet has been processed not before. Affected file is
215 * Fixed a [ClientConnection] parsing bug. The port was never
216 parsed correctly thus resulting to port 0. Affected file
217 silcd/serverconfig.c.
219 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
220 argument and did not set the broadcast packet flag. Affected
221 file silcd/packet_send.c. Fixed same bug in the function
222 silc_server_send_notify as well.
224 * If we receive NEW_ID packet for our own ID in the server, ignore
227 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
231 * Removed the nickname from the Private Message Payload.
232 Updated the code and the protocol specs.
234 * Updated protocol specs for submitting to the IETF.
236 * Tweaked the Random Number Generator a bit. Affected file
237 lib/silccrypt/silcrng.c. Exported a new function
238 silc_rng_[global]_add_noise which can be used to add more
241 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
243 * Do not parse packets with different timeout when protocol
244 is active -> may cause problem with rekey. Affected file
247 * When server receives signoff notify it must not create
248 new channel key if the client is on any channels since the
249 sender of the signoff notify will create it.
251 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
253 * Added printing of error messages during SKE protocol from the
254 failure packet sent by server during SKE. Affected file
257 * Removed the client's failure_callback handling with timeout
258 and handle it immediately when received.
260 * The SKE library returned wrong type in SUCCESS and FAILURE
261 packets. They must be 32 bit MSB not 16 bit MSB.
263 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
265 * Ok, rewrote the logic of the re-key and now it seems to work.
266 I tested it on high traffic with frequent re-keys without
267 problems. Added hmac_receive (and renamed hmac to hmac_send)
268 in SilcClientConnection in lib/silcclient/client.h and
269 in SilcIDListData in silcd/idlist.h. Also, removed the
270 SilcPacketParserContext's cipher and hmac fields as they are
271 not needed anymore and actually caused some problems when
272 the ciphers and hmac's changed underneath the packet parser.
274 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
276 * If re-key protocol is active then process the incoming packets
277 synchronously since we must assure that icoming packets encrypted
278 with the old key is processed before the new keys is set to
279 use. This is true other packets than for REKEY packets.
280 Affected file silcd/server.c. The same was done to client library
281 as well, affected file lib/silcclient/client.c.
283 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
285 * Fixed bug in client and server to accept the force send if
286 the packet is send from silc_[server/client]_packet_process
287 function. Otherwise the packets are never delivered, oops.
289 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
291 * Disable force sending of packets when REKEY protocol is active.
292 We must assure that no packet is sent directly when rekey is
293 performed. All packets must be sent through packet queue.
294 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
295 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
296 function is silc_[server/client]_packet_send_real to check
299 * Replaced the SIM paths from example config files to
300 /usr/local/modules. Also, make install creates now
301 /usr/local/silc/logs directory to hold all the SILC server
304 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
306 * Made the configure.in.pre work on Solaris. Patch by salo.
308 * Made all ciphers compatible with non-x86 machines. Defined
309 CBC mode macros into lib/silccrypt/ciphers_def.h.
311 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
313 * Fixed the make install.
315 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
317 * When MAC computation fails the silc_packet_decrypt returned 0
318 even though it was supposed to return -1. Fixed this. The
319 affected file is lib/silccore/silcpacket.c.
321 * Do not replace the config files in /etc/silc (in make install)
322 if they already exist. Affected file ./Makefile.am.
324 * Do not send re-key packets immediately but through packet queue.
325 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
327 * Changed silc_net_check_host_by_sock to return FALSE if the
328 IP/DNS could not be resolved. Though, it returns the IP address
329 now even if it could not resolve it (but returns also FALSE).
330 Affected file lib/silcutil/silcnet.[ch].
332 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
334 * Added silc_pkcs_decode_identifier to decode the public key's
335 identifier. Affected file lib/silccrypt/silpkcs.[ch].
336 Added also silc_pkcs_free_identifier. Added also new context
337 SilcPublicKeyIdentifier.
339 * Added -S option to the silc client. It is used to dump the
340 contents of the specified public key file.
342 * Changed the PKCS api to return the public key length when
343 setting the public key.
345 * Fixed a fatal bug in the public and private key file loading.
346 Affected file lib/silccrypt/silcpkcs.c.
348 * Execute the packet parsing for client with zero (0) timeout
349 if the protocol is active. Affected file silcd/server.c.
351 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * Made the key generation options to the silcd program. Added
354 -C option, equivalent to client's option.
356 * Added new [ServerKeys] config section to the server. It
357 configures the server's public and private key.
359 * Defined generic Public Key Payload into the protocol
360 specification to send specific type of public keys and
363 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
364 public key or certificate.
366 * Implemented the GETKEY command to the server and to the
367 client library and on user interface.
369 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
371 * Made preliminary `make install' work.
373 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
375 * Added SilcServerRekey context into silcd/idlist.h.
377 * Added the PFS support as defined in the specification to the
378 SKE protocol. Affected files lib/silcske/*.c.
380 * Added `ske_group' field to the SilcServerRekey context to hold
381 the number of the SKE group that is used with PFS in re-key.
382 Affected file silcd/idlist.h.
384 * Added PFS re-key support to the server. Affected file is
387 * Added silc_protocol_cancel to cancel execution of the next
388 state of the protocol. Affected file is
389 lib/silccore/silcprotocol.[ch].
391 * Added the re-key support with and without PFS to the client
392 library. Re-key is performed once in an hour, by default.
394 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
395 Added silc_client_rekey_callback and silc_client_rekey_final.
396 Affected files are lib/silcclient/protocol.[ch] and
397 lib/silcclient/client.[ch].
399 * Removed the `hmac_key' and `hmac_key_len' fields from the
400 SilcClientConnection structure; not needed. Affected file is
401 lib/silcclient/client.h.
405 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
407 * Do not ask whether user wants to use the negotiated private key
408 for private messages, just use it. Affected file is
409 silc/local_command.c.
411 * Added `send_enc_key' and `enc_key_len' fields to the
412 SilcIDListData structure since they are needed in the re-key
413 phase. Affected file is silcd/idlist.[ch].
415 * Implemented the simple re-key protocol into the server.
416 Affected files silcd/server.c and silcd/protocol.[ch]. The
417 re-key will be performed once in an hour, by default.
419 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
420 Added silc_server_rekey, silc_server_rekey_callback and
421 silc_server_rekey_final.
423 * Removed Tunneled flag from the protocol. Updated the code
424 and the specifications.
426 * Adde `pfs' field to the SilcIDListData to indicate whether
427 the PFS is to be performed in the re-key. Affected file is
430 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
432 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
433 int64 of at least the xintXX size. If void * is less that 4
434 bytes uint32 * will be used. Defined bool as boolean.
436 * Changed _ALL_ unsigned long and unsigned int to uint32,
437 unsgined short to uint16 in the source tree.
439 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
440 not handle clients that has entry->data.registered == FALSE.
441 They are not in the network anymore. Affected file is
444 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
446 * Implemented the sending of the SERVER_SIGNOFF notify in the
447 server. Affected file is silcd/server.c.
449 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
450 Added also silc_notify_payload_encode_args into the
451 lib/silccore/silcnotify.[ch].
453 * Implemented ther SERVER_SIGNOFF notify handling in the server.
454 Affected file silcd/packet_receive.c.
456 * Implemented the SERVER_SIGNOFF notify handling in the client
457 library. Affected file lib/silcclient/client_notify.c. Also,
458 implemnted the printing of the SERVER_SIGNOFF info to the
459 application. Affected file silc/client_ops.c.
461 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
462 if the deleting was successful. Affected file silcd/idlist.[ch].
464 * Added support for public key authentication in the connection
465 authentication protocol in the client library. Affected file
466 lib/silcclient/protocol.c.
468 * Changed the server's silc_idlist_get_clients_by_* interface
469 to support already allocated array so that new entries may be
470 added to pre-allocated array. Affected file silcd/idlist.[ch].
471 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
474 * All command reply functions in the server now calls the
475 pending command callback even if error occured. This way the
476 error will be delivered to the client as well. Affected files
477 silcd/command.c and silcd/command_reply.c.
479 * Fixed INFO command to return local server's info if no server
480 was provided. Affected file lib/silcclient/command.c.
482 * Removed RESTART command for good. Updated the code and the
485 * Rewrote parts of the task system. It is a bit simpler now.
486 Removed unsued task priorities. The affected files are
487 lib/silcutil/silctask.[ch].
489 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
491 * Moved the USERS printing from the library to the application.
492 Affected files lib/silcclient/command.c and silc/client_ops.c.
494 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
498 * Added channel key re-key support. The re-key is perfomed
499 only by the router and is done once in an hour. Added `rekey'
500 field to the SilcChannelEntry in the server. Affected files
501 silcd/server.c and silcd/idlist.h.
503 * Added silc_task_unregister_by_context into the file
504 lib/silcutil/silctask.[ch].
506 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
508 * Added SILC_UMODE_GONE mode to indicate when the client is not
509 present in the SILC network. Added also support to the local
510 command AWAY that will set this mode. Added support of showing
511 "xxx is gone" in WHOIS command. The USERS command shows the
514 * Fixed setting server and router operator privileges in the
515 server's UMODE command. Affected file silcd/command.c.
517 * Merged the SKE KE1 and KE2 payloads into one payload. The
518 new KE payload is equivalent to the old KE2 payload.
520 Cleaned up the SKE Start Payload parsing. It now uses the
521 simple buffer unformatting to do the parsing. A lot faster
524 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
525 to the SKE that is used to indicate whether both of the SKE
526 parties should perform authentication. By default only the
527 responder performs authentication. By setting this flag also
528 the initiator must do authentication. By default it is unset
529 since in normal SKE case, client to server connection, only
530 the responder should do authentication. When doing SKE between
531 two clients both should perform authentication. Updated the
532 code and the protocol specs.
534 * A little fix to IDENTIFY command in the server. Search the
535 client first by hash not nickname. Affected file is
538 * Fixed the silc_client_close_connection to support closing
539 the client to client connections wihtout deleting too much
540 data. Affected file lib/silcclient/client.c.
542 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
543 are received if protocol used to be active but is not anymore
544 the application would crash due to NULL pointer dereference.
545 Affected files silcd/server.c and lib/silcclient/client.c.
547 * Added `hash' field to the SilcClientConnection to include
548 the hash function negotiated in the SKE protocol.
550 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
551 to set the channel founder authentication data. A client can
552 claim the founder rights later by providing the authentication
553 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
554 This way the channel founder can regain the channel founder
555 privileges even it is left the channel. This works only on
556 local server and the client must be connected to the same
557 server to be able to regain the founder rights. Updated the
558 protocol specs accordingly.
560 Added support to the CMODE command in the client to set the
561 founder auth data. Read the README to see how to set it.
563 Added support to the CUMODE command to claim the founder
564 rights. Read the README to see how to do it.
566 Added support for the founder authentication to the Channel
567 Entry in the server. Affected file silcd/idlist.h.
569 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
570 server's CMODE command. Affected file silcd/command.c.
572 * Added the following new functions into lib/silccore/silcauth.[ch]:
573 silc_auth_get_method and silc_auth_get_data.
575 * The server now saves the remote hosts public key to the
576 SilcIDListData pointer. Affected file silcd/protocol.c.
578 * The normal server now does not remove the channel entry from
579 the cache if the founder authentication data is set. It used
580 to remove it if the founder was the last one on the channel on
581 the server and left the channel. The auth data is saved and
582 if the channel is re-joined later the old entry is used with
583 the old auth data. Affected files silcd/command_reply.c and
586 * Removed the `pkcs' field from the SilcIDListData structure
587 in the server; it is not used. Affected file silcd/idlist.h.
589 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
591 * Fixed packet processing on slow links. Partial packets were
592 never re-processed because the incoming data buffer was cleared
593 by the application. Application must not directly clear the
594 sock->inbuf, the packet processing routines handle it. Fixed
595 this in client library and in server.
597 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
599 * Fixed the WHOIS and IDENTIFY send reply function to really
600 check whether to send list or just one entry. Affected file
603 * Cleaned up the LEAVE command's channel key distribution. The
604 affected file silcd/command.c.
606 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
607 can enforce the channel mode as well. In that case the ID
608 includes the ID of the server. The code now enforces the
609 mode change if the router have different mode than the server.
611 * The notify client operation with CMODE_CHANGE notify can now
612 return NULL client_entry pointer if the CMODE was not changed
613 by client. Application must check for this.
615 * Added <Server ID> argument to INFO command to support server
616 info fetching by Server ID.
618 * Added silc_server_announce_get_channel_users to get assembled
619 packets of channel users of the specified channel. Affected
620 file silcd/server.[ch].
622 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
623 was freed underneath the ID Cache.
625 * Re-announce clients when the server received CHANNEL_CHANGE
626 notify from the router. Affected file silcd/packet_send.c.
628 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
630 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
631 crashed since it did not handle the fact that there is no cipher
632 called "3" and didn't check the error condition. Now fixed.
634 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
635 flag. It can be used to send message requests.
637 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
639 * Implemented the RESTART command in the client.
641 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
642 notice type messages. Added notice printing to the user
645 * The channel keys are not re-generated if the channel's mode
646 is PRIVKEY, ie private key on the channel exists. Affected
647 files silcd/server.c and silcd/command.c.
649 * Fixed a little bug in channel message delivery when channel
650 private keys are set in the server. Affected file is
653 * Changed the setting on channel->on_channel = TRUE from the
654 silc_client_save_channel_key to the JOIN command reply. The
655 key payload is not received if the private channel key is set.
656 Affected file lib/silcclient/command_reply.c and the
657 lib/silcclient/client_channel.c.
659 * When the CMODE_CHANGE notify is sent and the channel private
660 key mode is removed the channel key must be re-generated in
661 other cells as well. Added this support for the router in the
662 silcd/packet_receive.c.
664 * Added new local command NOTICE to send notice message on
665 channel. Affected file silc/local_command.[ch].
667 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
669 * Added new local command ME to the client. It is used to send
670 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
671 some action. Affected file silc/local_command.[ch].
673 * Changed channel_message and private_message client operations
674 to deliver the message flags to the application. Added also
675 the `flags' arguments to the silc_client_send_channel_message
676 and silc_client_send_private_message functions. Affected file
679 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
681 * Redefined the Private Message Payload to support private message
682 keys and to support the new private message flags. Updated
683 the protocol specs. Flags makes it possible to have for example
686 * Added new type SilcPrivateMessagePayload and defined an API
687 for it in the lib/silcclient/silcprivate.[ch].
689 * Tested private message private keys successfully. Tested the
690 private message key set, unset and list commands with the new
693 * Redefined the Channel Message Payload to include the channel
694 message flags (equal with private message flags) to support
695 for example CTCP style messages.
697 * Defined some of the message (for channel and private message)
698 flags. Updated the protocol specs and added the flags to the
699 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
701 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
703 * Added SilcKeyAgreementStatus type to the key agreement routines
704 to indicate the current status and error if one occured.
705 The status types are defined in the lib/silcclient/silcapi.h.
707 * Added new local command KEY that is used to set and unset private
708 keys for channels, set and unset private keys for private messages
709 with remote clients and to send key agreement requests and
710 negotiate the key agreement protocol with remote client. The
711 key agreement is supported only to negotiate private message keys,
712 it currently cannot be used to negotiate private keys for channels,
713 as it is not convenient for that purpose.
715 * Fixed a minor pending callback setting bug in the function
716 silc_client_get_client_by_id_resolve, now the function works.
717 Affected file lib/silcclient/idlist.c.
719 * Added function silc_net_get_local_port to get local bound
720 port by socket. Added to lib/silcutil/silcnet.[ch].
722 * Added `sockets' and `sockets_count' fields to the SilcClient
723 object. They hold the sockets of the listenning sockets in
724 the client. Listenning sockets may be for example the key
725 agreement server. Affected file lib/silcclient/client.[ch].
726 Added functions the silc_client_add_socket and the
727 silc_client_del_socket. They are exported to the application
730 * Added ~./silc/clientkeys to support other client's public keys.
732 * Renamed verify_server_key client operation to verify_public_key
733 and added one argument to indicate the type of the connection
734 (server, client etc.).
736 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
738 * Added silc_server_connection_auth_request to handle the
739 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
740 silcd/packet_receive.[ch].
742 * Added silc_server_send_connection_auth_request into the
743 silcd/packet_send.c to send the connection auth request packet.
745 * Cleaned up the silcd/protocol.c a bit and fixed some memory
748 * Fixed the public key authentication in responder side in the
749 server. The `auth_data' pointer includes the SilcPublicKey
750 not the path to the public key. Affected file silcd/protocol.c.
752 * Implemented the public key authentication in the initiator side
753 in the server. Affected file silcd/protocol.c.
755 * Removed the [RedirectClient] config section from the server
756 configuration. Is not needed and I don't want to implement it.
758 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
760 * Cleaned up the CMODE command in the server. It now works
761 correctly and supports all the modes defined in the protocol.
762 Affected file is silcd/command.c.
764 * Added `hmac_name' field to the SilcChannelEntry in the server
765 to hold the default HMAC of the channel. It can be set when
766 creating the channel (with JOIN command). Affected files
769 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
770 type to indicate the change of the current cipher and hmac
771 on the channel. Client can safely ignore the <cipher> argument
772 (if it chooses to do so) since the CHANNEL_KEY packet will
773 force the channel key change anyway. The <hmac> argument is
774 important since the client is responsible of setting the new
775 HMAC and the hmac key into use.
777 * Fixed the CMODE command in the client library as well.
779 * Tested CMODE command in router environment successfully.
781 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
783 * Show the version of the remote client (or server) when connecting
784 to the server. It is logged to the log file. Affected file
787 * Fixed the KILLED notify handling in the client library. The
788 client must be removed from all channels when receiving the
791 Also, do not remove the client entry when giving the KILL
792 command but when the KILLED notify is received.
794 * Removed silc_idlist_find_client_by_nickname from the server.
795 Not needed anymore. Affected files silcd/idlist.[ch].
797 * Implemented the CHANNEL_CHANGE notify type handling to the
798 server. Affected file silcd/server.c.
802 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
804 * Added silc_server_send_notify_invite to send the INVITE
805 notify between routers.
807 * Implemented the INVITE command correctly to the server.
809 * Implemented the INVITE notify type handling in the server.
811 * Implemented the INVITE command to the client library and on the
814 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
816 * Added function silc_server_get_client_resolve to find the
817 client entry by ID from all ID lists and then resolve it
818 (using WHOIS) if it cannot be found. Affected file is
821 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
823 * Implemented the BAN command to the client library.
825 * The JOIN command in the server now checks the invite list
828 * Changed the silc_command_reply_payload_encode_va and the
829 silc_command_payload_encode_va to support that if argument is
830 NULL it ignores and checks the next argument. Affected file
831 lib/silccore/silccommand.c.
833 * Added silc_server_send_notify_ban to send the BAN notify
834 type between routers.
836 * Chaned the silc_notify_payload_encode to support that if
837 argument is NULL it ignores and checks the next argument.
838 Affected file lib/silccore/silcnotify.c.
840 * Tested ban lists in router environment successfully.
842 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
844 * Implemented BAN command to the server, in silcd/command.[ch].
846 * Removed the BAN and INVITE_LIST modes from the CMODE command
849 * Added function silc_string_match to regex match two strings.
850 Affected files lib/silcutil/silcutil.[ch].
852 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * Redefined parts of the SilcChannelEntry in the server to support
855 the new ban and invite lists.
857 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
859 * Redefined the INVITE command. The same command can be used to
860 invite individuals to the channel but also to manage the invite
861 list of the channel (to add to and remove from the invite list).
862 Updated the protocol specs.
864 * Added new command SILC_COMMAND_BAN that can be used to manage
865 the ban list of the channel. Updated the protocol specs.
867 * Removed the channel modes: the SILC_CMODE_BAN and the
868 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
869 in the CMODE command. The equivalent features are now available
870 using INVITE and BAN commands. Updated the protocol specs.
872 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
873 in the network about change in the current ban list. The notify
874 type is not used by the client.
876 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
877 support the invite lists.
879 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
881 * Added new function silc_string_regexify that converts string
882 including wildcard characters into regex string that can
883 be used by the GNU regex library. Added into the file
884 lib/silcutil/silcutil.[ch].
886 Added silc_string_regex_combine to combine to regex strings
887 into one so that they can be used as one regex string by
888 the GNU regex library. Added into the file
889 lib/silcutil/silcutil.[ch].
891 Added silc_string_regex_match to match two strings. It returns
892 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
894 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * Imported GNU regex to the soruce tree into lib/contrib.
897 Fixed some compiler warning from the regex.c.
899 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
901 * Fixed MOTD command in the server to work in router environment.
903 * Fixed the MOTD command in the client library to support
904 the server argument in the command.
906 * Added `nickname_len' argument to the silc_idlist_add_client
907 in the server, as the `nickname' argument may be binary data
910 * Added silc_idlist_get_channels to return all channels from
913 * Implemented LIST command to the server. Affected file is
916 * Implemented the LIST command to the client library and on the
919 * Added [<user count>] argument to the LIST command reply.
920 With private channels the user count is not shown.
922 * Updated TODO and README.
924 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * The client entry's data.registered must be TRUE even with
927 global client entry on global client list. The data.registered
928 is used to check whether the client is anymore in the network,
929 for example with WHOWAS command so it must be valid.
931 * Fixed the WHOWAS command in the server. It now actually works
932 in router environment. Added function into silcd/command_reply.c
933 silc_server_command_reply_whowas_save.
935 * Added silc_idlist_purge function to the silcd/idlist.c
936 to periodically purge the ID Cache.
938 * Fixed INFO command in the server. It works now in router
939 environment. Added <server name> argument to the INFO command
940 reply. Updated the protocol specs.
942 * Fixed minor bug in silc_idcache_purge to not purge if the
943 expire value is zero.
945 * Fixed various bugs in WHOIS and IDENTIFY command handling as
946 they were buggy because of the WHOWAS information.
948 * Fixed local command MSG to handle the async resolving of
949 the remote client properly. It used to fail the first MSG.
950 Affected file silc/local_command.c.
952 * Added `data_len' field to SilcIDCache context.
954 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Update TODO. Todo in commands in the server.
958 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
960 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
961 used by routers as broadcast packet to inform other routers
962 about the changed user mode.
964 Implemented the notify handling in the server. Affected file is
965 silcd/packet_receive.c. Added the function
966 silc_server_send_notify_umode to the silcd/packet_send.[ch].
968 * Added new generic Channel Payload and deprecated the New Channel
969 Payload. The New Channel Payload is now the generic Channel
972 * Added new argument `mode' to the silc_server_send_new_channel
973 as it is required in the Channel Payload now.
975 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
976 and created a new and real SilChannelPayload to represent the
977 new generic Channel Payload. Implemented the encode/decode
978 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
980 * Added silc_server_get_client_channel_list to return the list
981 of channels the client has joined for WHOIS command reply.
982 Affected file silcd/server.[ch].
984 * Implemented the channel list sending in the WHOIS command reply
985 in server and in the client.
987 Implemented the channel list displaying on the user interface
988 as well. Affected file silc/client_ops.c.
990 * Added silc_channel_payload_parse_list to parse list of Channel
991 Payloads. It returns SilcDList list of SilcChannelPayloads.
992 Client for example can use this function to parse the list of
993 channels it receives in the WHOIS command reply. The caller
994 must free the list by calling silc_channel_payload_list_free.
995 Affected files lib/silccore/silcchannel.[ch].
997 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
999 * Added one new argument <user mode> to the WHOIS command reply
1000 to return the mode of the user in SILC. Updated the protocol
1003 Implemented it to the server and client.
1005 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1007 * Fixed the mode printing on the user interface on joining.
1008 Affected file silc/client_ops.c.
1010 * Implemented the UMODE command and user modes in general to the
1011 client library and to the user interface.
1013 * Implemented the UMODE command to the server.
1015 * The server now sends UNKNOWN_COMMAND error status if client sends
1016 unknown command. Affected file silcd/command.c.
1018 * All server commands now handle the command identifier the right
1019 way when sending the command reply to the client. The client can
1020 use to identify the command replies with the identifier.
1022 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1024 * Added silc_server_get_client_route to resolve the route to
1025 the client indicated by the client ID. Affected file is
1028 * Added silc_server_relay_packet as general function to relay
1029 packet to arbitrary destination. This deprecates functions
1030 like _send_private_message_key, _relay_notify etc. Affected
1031 file is silcd/packet_send.[ch].
1033 Removed silc_server_send_key_agreement,
1034 silc_server_send_private_message_key and
1035 silc_server_packet_relay_notify functions from the file
1036 silcd/packet_send.[ch].
1040 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1041 server. Affected file silcd/packet_receive.[ch].
1043 * Implemented the KILL command to the client. Implemented the
1044 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1045 Affected files lib/silcclient/command[_reply].c and
1046 lib/silcclient/client_notify.c. Implemented the KILL notify
1047 printing in the user inteface.
1049 * Fixed a lot silc_parse_nick memory leaks from the client
1050 library in the file lib/silcclient/command.c.
1052 * Changed the silc_server_send_notify_on_channels's `sender'
1053 argument from SilcSocketConnection to SilcClientEntry to
1054 check the sender as entry and not as connection object and not
1055 to send to the client provided as argument. The affected file
1056 is silcd/packet_send.[ch].
1058 * The notify packets that are destined directly to the client used
1059 to not to be processed by the server. Now changed that and the
1060 server processes all notify packets. After relaying the packet
1061 to the client the notify packet is processed in the server.
1063 * The silc_server_free_client_data now checks whether there is
1064 pending outgoing traffic for the client and purges the data to
1065 the network before removing the client entry.
1067 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1069 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1070 an client is killed from the SILC Network. Updated the protocol
1073 Added new function silc_server_send_notify_killed to the
1074 silcd/packet_send.[ch].
1076 * Added function silc_server_packet_relay_notify to relay notify
1077 packets that are destined directly to a client. In this case
1078 the server does not process the notify packets but merely relays
1079 it to the client. Affected file silcd/packet_send.[ch].
1081 Added also silc_server_packet_process_relay_notify to check
1082 whereto relay the notify. Affected file is
1083 silcd/packet_receive.[ch].
1085 * Implemented the KILL command to the server.
1089 * Added the backup schema desgined last fall to the protocol
1090 specs for everyone to see. The specification is in the
1091 *-spec-xx.txt draft and the packet type definitions for the
1092 backup routers is in *-pp-xx.txt draft. Thusly, added also
1093 new packet type SILC_PACKET_CELL_ROUTERS.
1095 * A big security problem in the implementation discovered. The
1096 signoff of an client did not cause new channel key generation
1097 which it of course should've done. The channel keys must be
1098 always re-generated when client leaves (or signoffs) the channel.
1099 The silc_server_remove_from_channels funtion now handles
1100 the channel key re-generation.
1102 * Added `sender' argument to the silc_server_send_notify_on_channels
1103 to not to send the client provided as argument. Affected file
1104 silcd/packet_send.[ch].
1106 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1108 * Implemented OPER and SILCOPER commands into the server and
1111 * Added silc_auth_verify and silc_auth_verify_data to verify
1112 the authentication directly from the authentication payload.
1113 It supports verifying both passphrase and public key based
1114 authentication. Affected file lib/silccore/silcauth.[ch].
1116 * Added `hash' field to the SilcIDListData structure. It is the
1117 hash negotiated in the SKE protocol. Affected file is
1120 * Slight redesigning of the SilcAuthPayload handling routines.
1121 Do not send SilcPKCS but SilcPublicKey as argument.
1123 * Implemented the public key authentication support to the
1124 serverconfig. The public key is loaded from the provided path
1125 and saved as authentication data to void * pointer. Thus,
1126 changed the unsigned char *auth_data to void *auth_data;
1128 * Fixed SHUTDOWN command to send the reply before the server
1129 is shutdown. :) Affected file silcd/command.c.
1131 * Fixed fatal bug in CONNECT command. The hostname was invalid
1132 memory and server crashed. Affected file silcd/command.c.
1134 * Fixed fatal bug in CLOSE command. The server_entry became
1135 invalid but was referenced later in the command. Affected file
1138 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1140 * Fixed fatal bug in failure packet handling. Server ignored
1141 the failure and thus crashed when it came.
1145 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1147 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1148 that the command may be executed only once in (about) 2 seconds.
1149 The old SILC_CF_LAG flag is same but allows command bursts up
1150 to five before limiting.
1152 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1153 server code. Various commands now includes the CF_LAG_STRICT
1154 flag to disallow any kind of miss-use of the command.
1156 * Fixed the silc_buffer_unformat to not to allocate any data
1157 if the length of the data is zero. It used to allocate the
1158 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1160 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1162 * Changed the format of AdminConnection configuration section
1163 in the server. Added username of the admin to the format.
1164 Affected files silcd/serverconfig.[ch].
1166 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1167 to return admin configuration data by host, username and/or
1170 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * Implemented WHOWAS command to the server. Added the functions:
1174 silc_server_command_whowas_parse,
1175 silc_server_command_whowas_send_reply,
1176 silc_server_command_whowas_from_client and
1177 silc_server_command_whowas_from_server
1179 * Added <Client ID> argument to the WHOWAS command reply. Updated
1180 the protocol specs accordingly.
1182 * Implemented WHOWAS command and command_reply to the client
1185 Implemented the WHOWAS printing on the user interface.
1187 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1189 * Added new argument to the WHOWAS command reply, the real name.
1190 It is an optional argument. Updated the protocol specs.
1192 * Added SilcIDCacheDestructor callback that is registered when
1193 the SilcIDCache is allocated. The callback is called when
1194 an cache entry in the ID Cache expires, or is purged from the
1195 cache. Added into lib/silccore/idcache.[ch].
1197 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1198 to destruct the client entries when the cache entry expires.
1199 Other ID Cache's in server and in the client library ignores
1202 * If the ID Cache entry's `expire' field is zero then the entry
1203 never expires. Added boolean `expire' argument to the
1204 silc_idcache_add function in the lib/silccore/idcache.[ch].
1205 If it is TRUE the default expiry value is used.
1207 * Added silc_server_free_client_data_timeout that is registered
1208 when client disconnects. By default for 5 minutes we preserve
1209 the client entry for history - for WHOWAS command.
1211 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Added support to the server to enforce that commands are not
1214 executed more than once in 2 seconds. If server receives
1215 commands from client more frequently, timeout is registered
1216 to process the commands. Affected file silcd/command.c.
1217 Added new function silc_server_command_process_timeout.
1219 * Changed NICK_NOTIFY handling in client library to check that
1220 if the client's nickname was changed, so there is no need to
1221 resolve anything from the server.
1223 * Removed error printing from the WHOIS and IDENTIFY commands.
1224 If error occurs then it is ignored silently in the client library.
1225 The application, however, may map the received error to
1226 human readable error string. The application currently maps
1227 the NO_SUCH_NICKNAME error to string.
1229 * Made the command status message public to the application. Moved
1230 them from lib/silcclient/command_reply.c to
1231 lib/silcclient/command_reply.h. The application can map the
1232 received command status to the string with the
1233 silc_client_command_status_message function.
1235 * Added check to the server to check that client's ID is same
1236 as the Source ID in the packet the client sent. They must
1239 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1241 * Added dist-bzip hook to the Makefile.am to make bzip2
1242 compressed distributions.
1244 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1246 * Server now enforces the maximum length for the nickname and
1247 the channel as protocol specification dictates. 128 bytes for
1248 nickname and 256 bytes for channel name.
1250 * Moved the WHOIS printing to the application. The client libary
1251 does not print out the WHOIS information anymore, the application
1252 must do it. Renamed silc_client_command_reply_whois_print to
1253 the silc_client_command_reply_whois_save.
1255 The client's idle time is also sent to the application now, and
1256 the idle is shown on screen.
1258 * Added silc_client_command_reply_identify_save to save the
1259 received IDENTIFY entries.
1261 * Do not check for channel private keys in message sending and
1262 reception if the channel does not have the PRIVKEY mode set.
1263 Affected file lib/silclient/client_channel.c.
1265 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1267 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1268 just surfaced after chaning the JOIN procedure.
1270 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1272 * Added silc_client_get_clients_by_list to get client entries
1273 from Client ID list, that is returned for example by JOIN
1274 and USERS command replies. The application should use this
1275 function for example when JOIN command reply is received to
1276 resolve the clients already on the channel (library does not
1277 do that anymore as USERS command reply is not used in the JOIN
1278 procedure anymore). Affected files lib/silcclient/silcapi.h and
1279 lib/silcclient/idlist.c.
1281 * JOIN command reply and USERS command reply returns now SilcBuffer
1282 pointers instead of unsigned char pointers when returning
1283 the client list and mode list.
1285 * Added <Client ID> argument to the JOIN command reply, mainly
1286 for the server to identify for which client the command was
1287 originally sent. Updated protocol specs accordingly.
1289 * Added SilcDlist private_key pointer to the SilcChannelEntry
1290 in the client to support the channel private keys. Affected
1291 file is lib/silcclient/idlist.h.
1293 * Added SilcChannelPrivateKey argument to the function
1294 silc_client_send_channel_message so that application can choose
1295 to use specific private ke if it wants to. If it is not provided,
1296 the normal channel key is used, unless private keys are set.
1297 In this case the first (key that was added first) is used
1298 as the encryption key.
1300 * Implemented the support for channel private key handling.
1301 Implemented the following functions:
1303 silc_client_add_channel_private_key,
1304 silc_client_del_channel_private_keys,
1305 silc_client_del_channel_private_key,
1306 silc_client_list_channel_private_keys and
1307 silc_client_free_channel_private_keys
1309 Affected file lib/silcclient/client_channel.c.
1311 * Added the support for the private keys in the channel message
1312 sending and encryption and in the message reception and
1313 decryption. Affected funtions are
1314 silc_client_send_channel_message and silc_client_channel_message.
1316 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1318 * Added SKE's key verify callback to the client library's
1319 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1321 * Removed the statement that server (or router) must send USERS
1322 command reply when joining to the channel so that the client
1323 knows who are on the channel. Instead, the client list and
1324 client's mode list is now sent in the JOIN command reply to the
1325 client who joined channel. This is better solution.
1327 * Added function silc_server_get_users_on_channel and function
1328 silc_server_save_users_on_channel to the silcd/server.[ch].
1330 * Removed function silc_server_command_send_users from the
1333 * Do not show topic on the client library anymore. The topic is
1334 sent in the command reply notify to the application and the
1335 application must show the topic now.
1337 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1339 * Added client searching by nickname hash into the IDENTIFY and
1340 WHOIS commands in the server as they were clearly missing from
1341 them. Affected file is silcd/command.c.
1343 * Fixed a bug in private message receiving in the client library.
1344 The remote ID was freed and it wasn't supposed, now it is
1347 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Minor fix to the channel payload; allocate the data area, as it
1350 needs to be of specific length.
1352 * If the key agreement port is zero then the operating
1353 system will define the bound port. Affected files are
1354 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1356 * Added new function silc_channel_payload_decrypt into the file
1357 lib/silccore/silcchannel.[ch].
1359 * Moved the channel message etc, check from silc_packet_decrypt
1360 to applications. The library calls now a generic
1361 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1362 when the packet is either normal or special. This was done to
1363 allow more wide range of checking that was not allowed when
1364 the code was in library. Now applications can do virtually any
1365 checks to the packet and return to the library the decision how
1366 the packet should be processed. Affected files are
1367 lib/silccore/silcpacket.[ch].
1369 Added silc_server_packet_decrypt_check to the server and
1370 silc_client_packet_decrypt_check to the client library.
1372 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1373 to send with specified source and destination information.
1375 * Channel message delivery between routers was broken after the
1376 channel key distribution was fixed earlier. The channel key
1377 was used be to distributed to other routers as well which is not
1378 allowed by the protocol. Now this is fixed and channel keys
1379 really are cell specific and the channel message delivery between
1380 routers comply with the protocol specification.
1382 * Fixed various commands in server to check also the global list
1383 for the channel entry and not just the local list. The affected
1384 file silcd/command.c.
1386 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Added assert()s to buffer formatting and unformatting routines
1389 to assert (if --enable-debug) when error occurs. Affected
1390 file: lib/silcutil/silcbuffmt.c.
1392 * Changed to auto-reconnect to check whether the remote host is
1393 router and register the re-connect timeout if it is. It used
1394 to check that whether we are normal server, but router must do
1395 auto-reconnect with another router as well. Affected file
1398 * Removed the [<key len>] option from CMODE command as the cipher
1399 name decides the key length, nowadays. See the defined ciphers
1400 from the protocol specification.
1402 * Added [<hmac>] option to the CMODE command to define the HMAC
1403 for the channel. Added SILC_CMODE_HMAC channel mode.
1405 * Added [<hmac>] option for the JOIN command so that user can
1406 select which HMAC is used to compute the MACs of the channel
1409 * Added Hmac field to the Channel Message Payload. The integrity
1410 of plaintext channel messages are now protected by computing
1411 MAC of the message and attaching the MAC to the payload. The
1412 MAC is encrypted. Now, it is clear that this causes some
1413 overhead to the size of the packet but rationale for this is that
1414 now the receiver can verify whether the channel message decrypted
1415 correctly and also when private keys are set for the channel the
1416 receiver can decrypt the packet with several keys and check from
1417 the MAC which key decrypted the message correctly.
1419 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1420 lib/silccrypt/silccipher.[ch].
1422 * Added silc_hash_len to return the digest length into the
1423 lib/silcrypt/silchash.[ch].
1425 * Rewrote parts of Silc Channel Payload interface in the
1426 lib/silccore/silcchannel.[ch]. The encode function now also
1427 encrypts the packet and parse function decrypts it.
1429 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1431 * Fixed a minor formatting bug in the SKE's key material processing.
1432 It actually might have processed the keys wrong way resulting
1435 * Redefined the mandatory HMAC algorithms and added new algorithms.
1436 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1437 and hmac-md5 truncated to 96 bits. The mandatory is now
1438 hmac-sha1-96. Rest are optional (including the one that used
1439 to be mandatory). Rationale for this is that the truncated HMAC
1440 length is sufficient from security point of view and can actually
1441 make the attack against the HMAC harder. Also, the truncated
1442 HMAC causes less overhead to the packets. See the RFC2104 for
1445 * Added new [hmac] configuration section. The SKE used to use
1446 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1447 is of course wrong. The official names that must be proposed in
1448 the SKE are the ones defined in the protocol specification
1449 (hmac-sha1-96 for example). The user can configure any hmac
1450 using any hash function configured in the [hash] section. At
1451 least, the mandatory must be configured.
1453 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1455 * Added HMAC list to the SKE proposal list. It has now both
1456 hash algorithm list and HMAC list. This makes the protocol
1457 incompatible with previous versions. The SKE now seems to work
1458 the way it is supposed to work, for the first time actually.
1460 * Defined plain Hash algorithms to the protocol specification.
1463 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1465 * Implemented support for key agreement packets into the server.
1466 Added functions silc_server_key_agreement and
1467 silc_server_send_key_agreement. Other than these functions,
1468 server has nothing to do with this packet.
1470 * Added support for private message key packets into the server.
1471 Added functions silc_server_private_message_key and
1472 silc_server_send_private_message_key.
1476 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1477 called in the protocol's final callback instead in the END
1478 protocol state. This makes a little more sense and in the same
1479 time in client we can use the same protocol routines for normal
1480 key exchange and to key agreement packet handling as well.
1482 * Added to both client's and server's KE protocol context the
1483 SilcSKEKeyMaterial pointer to save the key material. We will
1484 bring the key material to the protocol's final callback by doing
1485 this. The final callback must free the key material.
1487 * Added SKE's packet_send callback into client's KE protocol
1488 context so that the caller can choose what packet sending function
1489 is used. This way we can use different packet sending when
1490 doing normal SKE when doing key agreement packet handling (in
1491 the key agreement packet handling we do not want to encrypt
1494 * Implemented the responder side of the key agreement routines
1495 in the client. The client can now bind to specified port and
1496 accept incoming key negotiation. The key material is passed
1497 to the application after the protocol is over.
1499 * Implemented the processing of incoming Key Agreement packet
1500 in the client. Added function silc_client_key_agreement to
1503 * Implemented the intiator side of the key agreement routines
1504 in the client. The client can now initiate key agreement with
1505 another remote client. The key material is passed to the
1506 application after the protocol is over.
1508 * Created client_keyagr.c to include all the key agreement
1511 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1512 SILC_TASK_CALLBACK except that it is not static.
1514 * Created client_notify.c and moved the Notify packet handling
1515 from the client.[ch] into that file.
1517 * Created client_prvmsg.c and moved all private message and
1518 private message key routines from the client.[ch] into that file.
1520 * Create client_channel.c and moved all channel message and
1521 channel private key routines from the client.[ch] into that file.
1523 * Changed silc_client_get_client_by_id_resolve to resolve with
1524 WHOIS command instead of IDENTIFY command, in the file
1525 lib/silclient/idlist.c.
1527 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1529 * Implemented the SKE's responder side to the Client library.
1531 * When FAILURE is received to the protocol do not trust it
1532 blindly. Register a timeout to wait whether the remote closes
1533 the connection as it should do it, only after that process the
1534 actual failure. This was changed to both client and server.
1536 * Added client_internal.h to include some of the structures
1537 there instead of client.h in lib/silcclient/.
1539 * Added function silc_task_unregister_by_callback to unregister
1540 timeouts by the callback function.
1542 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1544 * Some "Incomplete WHOIS info" errors has been appearing on the
1545 log files. Took away the entry->userinfo check from WHOIS
1546 reply sending. The entry->userinfo is now " " if client did not
1547 provide one. I thought this was fixed earlier but something
1548 is wrong still. Let's see if the error still appears.
1550 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1552 * Fixed a minor bug in the login when the channel key is
1553 re-generated in the server. It used to generate the key in
1554 wrong order and thus caused problems in the channel traffic.
1556 * Fixed a minor bug in channel key distsribution after
1557 KICK command. The key was not sent to the router even though
1560 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1562 * Added silc_ske_process_key_material_data as generic routine
1563 to process any key material as the SILC protocol dictates. The
1564 function is used by the actual SKE library but can be used by
1565 applications as well. This relates to the private message keys
1566 and the channel private keys since they must be processed the
1567 same way the normal SILC session keys. The protocol dictates
1568 this. Affected files: lib/silcske/silcske.[ch].
1570 Added also silc_ske_free_key_material to free the
1571 SilcSKEKeyMaterial structure.
1573 * Defined silc_cipher_set_key function to set the key for
1574 cipher without using the object's method function. The affected
1575 files: lib/silccrypt/silccipher.[ch].
1577 * Implemented silc silc_client_add_private_message_key,
1578 silc_client_add_private_message_key_ske,
1579 silc_client_del_private_message_key,
1580 silc_client_list_private_message_keys and
1581 silc_client_free_private_message_keys functions in the
1584 Added functions silc_client_send_private_message_key to send
1585 the Private Message Key payload and silc_client_private_message_key
1586 to handle incoming Private Message Key payload.
1588 * Added Cipher field to the Private Message Key payload to set
1589 the cipher to be used. If ignored, the default cipher defined
1590 in the SILC protocol (aes-256-cbc) is used.
1592 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1594 * Removed lib/silcclient/ops.h file.
1596 Redefined parts of the SILC Client Library API. Created new
1597 file silcapi.h that deprecates the ops.h file and defines the
1598 published Client Library API. Defined also private message key
1599 API and channel private key API into the file.
1601 This is the file that the application must include from the
1602 SILC Client Library. Other files need not be included by
1603 the application anymore.
1605 * Added new key_agreement client operation callback and also
1606 defined the Key Agreement library API for the application.
1608 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1611 is used by clients to request key negotiation between another
1612 client in the SILC network. If the negotiation is started it
1613 is performed using the SKE protocol. The result of the
1614 negotiation, the secret key material, can be used for example
1615 as private message key.
1617 Implemented the Key Agreement payload into the files
1618 lib/silccore/silauth.[ch].
1620 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1622 * Redefined ciphers for the SILC protocol. Added some new ciphers
1623 and defined the key lengths for the algorithms. Changed the
1624 code accordingly. The default key length is now 256 bits.
1626 * Fixed SKE key distribution function silc_ske_process_key_material
1627 when the key length is more than 128 bits. The default key
1628 length in SILC is now 256 bits.
1630 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1631 to indicate unsupported algorithm.
1633 * Renamed rijndael.c to aes.c and all functions as well.
1635 * Fixed a long standing channel key setting bug in client library.
1636 Weird that it has never surfaced before.
1638 * Fixed bug in channel deletion. If the entire channel is removed
1639 then it must also delete the references of the channel entry
1640 from the client's channel list as the client's channel entry and
1641 the channel's client entry share same memory.
1643 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Implemented CONNECT and SHUTDOWN commands in the client.
1647 * Implemented CLOSE command to the client.
1649 * Added the function silc_idlist_find_server_by_name into the
1650 files silcd/idlist.[ch].
1652 Added the function silc_idlist_find_server_by_conn into the
1653 files silcd/idlist.[ch].
1655 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1657 * DIE command was renamed to SHUTDOWN. Updated the both code
1660 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1661 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1663 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1666 * Added function silc_server_create_connection function to create
1667 connection to remote router. My server implementation actually
1668 does not allow router to connect to normal server (it expects
1669 that normal server always initiates the connection to the router)
1670 so the CONNECT command is only good for connecting to another
1673 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1675 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1676 or some other client was kicked from the channel.
1678 Implemented the handling of the notify type to both client
1681 Implemented silc_server_send_notify_kicked to send the KICKED
1682 notify. It is used to send it to the server's primary router.
1684 * Implemented the KICK command into server and client.
1686 * Added `query' argument to the silc_idlist_get_client function
1687 to indicate whether to query the client from server or not if
1690 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1691 to indicate that the client is not channel founder.
1695 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1697 * Removed the rng context from SilcPacketContext structure and
1698 changed that the packet routine uses the Global RNG API.
1700 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1702 * Added support for quit message that client can "leave" on the
1703 channel when it quits the SILC. It is ditributed inside the
1704 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1706 Added silc_server_free_client_data that will take the
1707 signoff message as argument.
1709 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1711 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1713 * Updated parts of the protocol specification to keep it up
1716 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1718 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1719 payloads in one packet.
1721 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1722 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1723 use now the new List flag.
1725 * Also deprecated the following packet types: REPLACE_ID,
1726 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1728 * Added list support for Notify packet in server.
1730 * Added silc_server_send_notify_channel_change to send the
1731 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1732 the silc_server_send_replace_id.
1734 * Added silc_server_send_notify_nick_change to send the
1735 NICK_CHANGE notify type. Deprecates the function
1736 silc_server_send_replace_id.
1738 * Added silc_server_send_notify_join to send the JOIN notify type.
1739 Deprecates the function silc_server_send_new_channel_user.
1741 * Added silc_server_send_notify_leave to send LEAVE notify type.
1742 Deprecates the function silc_server_send_remove_channel_user.
1744 * Added silc_server_send_notify_cmode and
1745 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1746 types. Deprecates the silc_server_send_set_mode function.
1748 * Added SERVER_SIGNOFF notify type to indicate that server has
1749 quit. This means that all clients on the channel from that
1750 server will drop. This can be also used when netsplit happens.
1752 Deprecated REMOVE_ID packet type since it is not needed anymore
1755 Added silc_server_send_notify_server_signoff to send the
1756 SERVER_SIGNOFF notify type. Deprecates the function
1757 silc_server_send_remove_id.
1759 Added also silc_server_send_notify_signoff to send the
1760 SIGNOFF notify type.
1762 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1763 SILC protocol from this day on. Changed the protocol
1764 specification as well.
1766 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1767 notify type. It is used between routers to notify about
1768 topic changes on a channel.
1770 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1773 * Partly updated the protocol specification to comply with the
1774 changes now made. It is still though a bit outdated.
1776 * The JOIN notify type now takes one extra argument <Channel ID>.
1777 The packet used to be destined to the channel but now the
1778 JOIN type may be sent as list thus it is impossible to
1779 destine it to any specific channel. By adding this argument
1780 it is again possible.
1782 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1784 * Added CREDITS file. The CHANGES and CREDITS file will appear
1785 in the distribution as well.
1787 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1789 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1790 types in the server's silcd/packet_receive.c.
1792 * Implemented CMODE and CUMODE to work in router environment.
1794 * Fixed minor encoding and decoding buglet from the
1795 lib/silccore/silcmode.c.
1797 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1800 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1802 * Changed all SilcConfigServer* and silc_config_server* to
1803 SilcServerConfig* and silc_server_config*, respectively.
1806 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1808 * Associated the ID (client or server ID) to the Authentication
1809 Payload to avoid any possibility of forging. Updated the
1810 protocol specification and the code accordingly.
1812 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1814 * The RSA key length is now save to the RsaKey context in the
1815 key generation process in lib/silccrypt/rsa.c. The key length
1816 is now used to figure out the maximum size of the block allowed
1817 to be encrypted/signed.
1819 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1820 is equivalent to the silc_mp_mp2bin but does not allocate any
1823 * Changed silc_mp_mp2bin API to take length argument. If it is
1824 non-zero then the buffer is allocated that large. If zero, then
1825 the size is approximated using silc_mp_sizeinbase, which however
1828 * Created Global RNG API which is global RNG that application can
1829 initialize. After initializing, any routine anywhere in the
1830 code (including library) can use RNG without allocating a new
1831 RNG object. This was done to allow this sort of use of the
1832 RNG in code that has no chance to allocate RNG object. All
1833 applications currently allocate this and many routines in the
1834 library use this. Affected file lib/silccrypt/silcrng.[ch].
1836 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1837 it to use the Global RNG API.
1839 * Defined Authentication Payload into protocol specification that
1840 is used during SILC session to authenticate entities. It is
1841 used for example by client to authenticate itself to the server
1842 to obtain server operator privileges.
1844 Implemented this payload into the lib/silccore/silcauth.[ch].
1845 Implemented also routines for public key based authentication
1846 as the new protocol specification dictates.
1848 Moved definitions of different authentication methods from
1849 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1851 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1852 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1853 silc_pkcs_verify_with_hash functions into the file
1854 lib/silccrypt/silcpkcs.[ch].
1856 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1858 * The client entry's userinfo pointer must be always valid.
1859 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1860 will fail since it requires the userinfo. Now, the userinfo
1861 is allocated as "" if actual userinfo does not exist. Actually,
1862 it must exist and it is totally Ok to drop client connections
1863 that does not announce the userinfo. However, we will make
1864 this workaround for now.
1866 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1867 to return the remote port by socket.
1869 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1871 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1872 SILC_SERVER_PENDING_EXEC and added an new macro
1873 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1874 data or when error occurs while processing the pending command.
1876 Added new argument `destructor' into silc_server_command_pending
1877 and to the SilcServerCommandPending object. This destructor is
1878 now called after calling the pending callback or if error occurs
1879 immediately. If error occurs the actual pending callback won't
1880 be called at all - only the destructor. The destructor may be
1881 NULL if destructor is not needed.
1883 All this applies for client library code as well. Similar
1884 changes were made there as well for the pending commands.
1886 In the client, the application must now allocate the
1887 SilcClientCommandContext with the silc_client_command_alloc
1890 * Added reference counter to the SilcServerCommandContext. Added
1891 function silc_server_command_alloc and silc_server_command_dup
1894 Same type of functions added to the client library for the same
1897 * Removed the cmd_ident from IDListData away since it is now
1898 global for all connections. It is the command identifier used
1899 in command sending and with pending commands. The affected file
1902 * Added reference counter to the SilcSocketConnection objecet to
1903 indicate the usage count of the object. The object won't be
1904 freed untill the reference counter hits zero. Currently only
1905 server uses this, and client ignores it. The client must be
1906 set to use this too later. The affected files are
1907 lib/silccore/silcsockconn.[ch]. Added also the function
1908 silc_socket_dup to increase the reference counter.
1910 This was mainly added because it is possible that the socket
1911 is removed underneath of pending command or other async
1912 operation. Now it won't be free'd and proper DISCONNECTING
1913 flags, etc. can be set to avoid sending data to connection that
1914 is not valid anymore.
1916 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1917 the connection. After that it sets SILC_SET_DISCONNECTED.
1918 It is, however, possible that the socket data is not still freed.
1919 The silc_server_packet_process now checks that data is not
1920 read or written to connection that is DISCONNECTED. The socket
1921 get's freed when the reference counter hits zero.
1923 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1925 * Changed the client operation API: channel_message operation's
1926 `sender' is now the client entry of the sender, not the nickname
1927 and the `channel' is the channel entry, not the channel name.
1929 In the private_message operation the `sender' is now also the
1930 client entry of the sender not the nickname.
1932 Affected file is lib/silcclient/ops.h and all applications
1933 using the client operations.
1935 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1937 * Moved the calling of ops->connect() from connect_to_server_final
1938 into receive_new_id functin since that is the point when the
1939 client is actually allowed to send traffic to network. The
1940 affected file is lib/silcclient/client.c.
1942 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1944 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1945 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1946 (if needs broadcasting) instead of broadcasting the packets one
1947 by one which would make a burst in the network traffic.
1949 * Added `broadcast' argument to the functions in silcd/server.[ch]
1950 silc_server_create_new_channel[_with_id] to indicate whether
1951 to send New Channel packet to primary router.
1953 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1955 * Added new function into the silcd/server.[ch] files:
1956 silc_server_create_new_channel_with_id to create new channel with
1957 already existing Channel ID.
1959 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1960 lib/silccore/silcpacket.h. This packet is used t send list of
1961 Set Mode payloads inside one packet. Server uses this to set
1962 the modes for the channels and clients on those channels, that it
1963 announced to the router when it connected to it. The protocol
1964 specification has been updated accordingly.
1966 * The silc_server_new_channel did not handle the packet coming
1967 from normal server as it normally does not send that. However,
1968 when it announces its channels it does send it. Implemented
1969 the support for that.
1971 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1972 into the file lib/silccore/id.h.
1974 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1976 * Fixed memory leaks in the functions silc_idlist_del_client,
1977 silc_idlist_del_channel and silc_idlist_del_server in the file
1978 silcd/idlist.c. All of those leaked like a sieve.
1980 * Fixed some small memory leaks in the client's function
1981 silc_client_notify_by_server.
1983 * Added functions into silcd/server.c: silc_server_announce_clients,
1984 silc_server_announce_channels and silc_server_announce_server.
1985 These functions are used by normal and router server to announce
1986 to its primary router about clients, channels and servers (when
1987 router) that we own. This is done after we've connected to the
1990 These functions effectively implements the following packet types:
1991 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1992 and SILC_PACKET_NEW_ID_LIST.
1994 * Added new functions into the silcd/packet_receive.[ch]:
1995 silc_server_new_id_list, silc_server_new_channel_list and
1996 silc_server_new_channel_user_list to handle the incoming
1997 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1999 * Added support of changing Channel ID in the function
2000 silc_server_replace_id. If the server that announces a channel
2001 to the router already exists in the router (with same name but
2002 with different Channel ID), router is responsible to send
2003 Replace ID packet to the server and force the server to change
2004 the Channel ID to the one router has.
2006 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2007 client that the Channel ID has been changed by the router. The
2008 normal server sends this to the client. Client must start using
2009 the new Channel ID as the channel's ID.
2011 Implemented handling of this new type into lib/silcclient/client.c
2012 into the function silc_client_notify_by_server.
2014 * Added new function silc_idlist_replace_channel_id into the files
2015 silcd/idlist.[ch] to replace the Channel ID.
2017 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2019 * Call silc_server_command_identify_check always when processing
2020 the IDENTIFY command in silcd/command.c
2022 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2024 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2025 send keepalive packets. The packet can be sent by clients,
2026 servers and routers.
2028 Added function silc_socket_set_heartbeat into the file
2029 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2030 If not set, the heartbeat is not performed. The actual
2031 heartbeat is implemented in the low level socket connection
2032 library. However, application is responsible of actually
2035 Added silc_server_send_heartbeat to send the actual heartbeat
2036 packet into silcd/packet_send.[ch]. Server now performs
2037 keepalive with all connections.
2039 * Added silc_task_get_first function into lib/silcutil/silctask.c
2040 to return the timeout task with shortest timeout. There was a bug
2041 in task unregistration that caused problems. TODO has been
2042 updated to include that task system must be rewritten.
2044 * The client library will now resolve the client information when
2045 receiving JOIN notify from server for client that we know but
2046 have incomplete information.
2048 * Rewrote parts of silc_server_remove_from_channels and
2049 silc_server_remove_from_one_channel as they did not remove the
2050 channel in some circumstances even though they should've.
2052 * Encryption problem encountered in server:
2054 The LEAVE command used to send the Channel Key packet to the
2055 router immediately after generating it. However, the code
2056 had earlier sent Remove Channel user packet but not immediately,
2057 ie. it was put to queue. The order of packets in the router
2058 was that Channel Key packet was first and Remove Channel User
2059 packet was second, even though they were encrypted in the
2060 reverse order. For this reason, MAC check failed. Now, this
2061 is fixed by not sending the Channel Key packet immediately but
2062 putting it to queue. However, this is more fundamental problem:
2063 packets that are in queue should actually not be encrypted
2064 because packets that are sent immediately gets encrypted
2065 actually with wrong IV (and thus MAC check fails). So, packets
2066 that are in queue should be encrypted when they are sent to
2067 the wire and not when they put to the queue.
2069 However, the problem is that the current system has not been
2070 designed to work that way. Instead, the packet is encrypted
2071 as soon as possible and left to the queue. The queue is then
2072 just purged into wire. There won't be any fixes for this
2073 any time soon. So, the current semantic for packet sending
2076 o If you send packet to remote host and do not force the send
2077 (the packet will be in queue) then all subsequent packets to the
2078 same remote host must also be put to the queue. Only after the
2079 queue has been purged is it safe again to force the packet
2082 o If you send all packets immediately then it safe to send
2083 any of subsequent packets through the queue, however, after
2084 the first packet is put to queue then any subsequent packets
2085 must also be put to the queue.
2087 Follow these rules and everything works fine.
2089 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2091 * Added new function silc_server_remove_clients_by_server to
2092 remove all client entries from ID list when the server connection
2093 is lost. In this case it is also important to invalidate all
2094 client entires as they hold the invalid server entry. This
2095 fixes fatal bug when server has lost connection and will reconnect
2098 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2100 * Made some sanity checks to silc_server_daemonise like to check
2101 whether the requested user and group actually exists.
2103 * Added sanity check to SKE's silc_ske_responder_finish to check
2104 that the public and private key actually is valid.
2106 * Invalidate the client's nickname when receiving Replace ID
2107 packet and the Client ID is being replaced. This means that the
2108 server will query the nickname if someone needs it (client)
2111 * Sort the ID Cache in client library when the ID Cache data
2112 has changed (needs sorting).
2114 * Do not allow for SILC client to create several connections to
2115 several servers. The client does not support windows right now
2116 and generating multiple connections causes weird behaviour.
2118 Irssi-silc client does support windows and can handle several
2119 connections without problems, see: www.irssi.org and SILC plugin.
2121 * Fixed some places where client was added to the IDList. The
2122 rule of thumb is following (in order to get everything right):
2123 If the client is directly connected local client then the
2124 `connection' argument must be set and `router' argument must be
2125 NULL to silc_idlist_add_client function. If the client is not
2126 directly connected client then the `router' argument must
2127 bet set and the `connection' argument must be NULL to the
2128 silc_idlist_add_client function.
2130 * The funtion silc_server_packet_send_local_channel actually did
2131 not check whether the client was locally connected or not. It
2132 does that now. Fixed a bug related to LEAVE command.
2134 * Fixed Remove Channel User payload parsing bug in server's
2135 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2137 * The server's silc_server_save_channel_key now checks also the
2138 global ID list for the channel as it might not be in the local
2139 list. Fixed a bug related to LEAVE command.
2141 * Is this the end of the [<unknown>] buglet that has been lurking
2142 around for a long time? A little for loop fix in server's
2143 silc_server_command_whois_parse that is used by both IDENTIFY
2144 and WHOIS command. At least, this was a clear bug and a cause
2145 of one type of [<unknown>] buglet.
2147 * WHOIS and IDENTIFY commands call the function
2148 silc_server_command_[whois/identify]_check function even if
2149 we are not router server.
2151 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2153 * Added --with-gmp configuration option. If set the GMP
2154 is always compiled in the SILC source tree. If not set then
2155 it is checked whether the system has the GMP3 installed. If
2156 it has then the GMP won't be compiled (the system's headers
2157 and library is used), if it doesn't have it then the GMP is
2158 compiled in the SILC source tree.
2160 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2162 * Changed RSA private exponent generation to what PKCS #1
2163 suggests. We try to find the smallest possible d by doing
2164 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2165 not security fix but optimization.
2167 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2169 * Added new config entry [Identity] to fork the server and run
2170 it as specific user and group. A patch from Bostik.
2172 * Imported Dotconf configuration library into lib/dotconf.
2173 This will be used to create the SILC configuration files later.
2174 It will appear in the distsribution after this commit.
2176 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * A big code auditing weekend happening. Auditing code for
2179 obvious mistakes, bugs and errors. Also, removing any code
2182 Removed files for being obsolete:
2184 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2185 inline in the file lib/silcutil/silcbuffer.h)
2187 o lib/silcutil/silcbufutil.c (the header has inline versions)
2189 Changed code to fix possible error conditions:
2191 o The buffer formatting routines now check that the destination
2192 buffer really has enough space to add the data. This applies for
2193 both buffer formatting and unformatting
2194 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2195 unformatting was changed to accomodate following rules:
2196 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2197 sent to the function while XXX_*STRING will not allocate or copy
2198 the data into the buffer. Instead it sets the pointer from the
2199 buffer into the pointer sent as argument (XXX_*STRING used to
2200 require that the pointer must be allocated already). This change
2201 makes this whole thing a bit more consistent and more optimized
2202 (note that the data returned in the unformatting with XXX_*STRING
2203 must not be freed now). The routines return now -1 on error.
2205 o Tried to find all code that use buffer_format and buffer_unformat
2206 and added return value checking to prevent formatting and
2207 especially unformatting errors and possible subsequent fatal
2210 o Changed ske->x and ske->KEY to mallocated pointers in
2211 lib/silcske/silcske.h. Fixed possible data and memory leak.
2213 o Added return value checking to all *_parse* functions. Fixed
2214 many memory leaks as well.
2216 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2217 so that buffer overflows would not happen. All code now also
2218 checks the return value as it can fail.
2220 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2222 * Added reconnection support to server if the normal server looses
2223 its connection to the router (for example if router is rebooted).
2224 The server performs normal reconnection strategy implemented
2225 to the server. Affected file silcd/server.c.
2227 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2229 * Added new packet type SILC_PACKET_SET_MODE that is used to
2230 distribute the information about changed modes (for clients,
2231 channels and clients channel modes) to all routers in the
2232 network. Updated the protocol specification accordingly.
2234 Added functions into silcd/packet_send.c and
2235 silcd/packet_receive.c: silc_server_send_set_mode,
2236 silc_server_set_mode.
2238 Added new files silcmode.[ch] into lib/silccore that implements
2239 the encoding and decoding of Set Mode Payload. Added new type
2240 SilcSetModePayload. Moved the definitions of different modes
2241 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2243 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2245 * Oops, a little mistake in server's connection authentication
2246 protocol. The protocol is not ended with FAILURE but with
2247 SUCCESS if the authentication is Ok. :) Affected file is
2250 * Implemented NICK_CHANGE notify handling in server in the file
2251 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2252 the local clients on the channel. After the changing nickname
2253 in router environment snhould work and the [<unknown>] nickname
2254 should appear no more.
2256 The silc_server_replace_id function that receives the Replace ID
2257 payload now sends the NICK_CHANGE notify type also in the file
2258 silcd/packet_receive.c
2260 * Changed WHOIS and IDENTIFY command to support the maximum amount
2261 of arguments defined in protocol specs (3328 arguments). This
2262 fixed a bug that caused problems when there were more than three
2265 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2267 * Added extra parameter, command identifier, to the
2268 silc_client_send_command so that explicit command identifier
2271 Changed that ID list routines uses specific command identifier
2272 when sending WHOIS/IDENTIFY requests to the server so that they
2273 can be identified when the reply comes back.
2275 Affected files lib/silcclient/command.[ch],
2276 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2278 * Added `sender' argument to silc_server_packet_send_to_channel
2279 to indicaet the sender who originally sent the packet to us
2280 that we are now re-sending. Ignored if NULL. Affected file
2281 silcd/packet_send.[ch].
2283 * Added some server statistics support in silcd/server_internal.h
2284 SilcServerStatistics structure and around the server code. Also
2285 send some nice statistics information when client is connecting
2288 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2290 * Fixed channel ID decoding in server's JOIN command reply in
2291 silcd/command_reply.c
2293 * Fixed braodcasting of replace ID payload to not to send it if
2294 we are standalone server in silcd/packet_receive.c.
2296 * Fixed all channel message sending routines to not to send
2297 packets to clients that has router set, since they are routed
2298 separately in the same function earlier. Affects file
2299 silcd/packet_send.c and all channel packet sending functions.
2301 * In USERS reply, res_argv[i] are not allocated, the table
2302 is allocated. Thus changed that free the table, not its
2305 * In server's whois_check and identify_check if the client is
2306 locally connected do not send any WHOIS commands - they are not
2309 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2311 * Fixed some minor bugs in client when sending WHOIS command. The
2312 arguments was in wrong order.
2314 * Removed statis function add_to_channel from server in
2315 silcd/command.c that was previously used with the joining but
2318 * Tested USERS command in router environment successfully with two
2319 routers, two servers and two clients.
2321 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2323 * Reorganized the USERS command and command reply in client library
2324 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2325 When the command is given by user we register a pending command
2326 callback that will reprocess the command after the reply has been
2327 received from the server. When reprocessing the packet we then
2328 display the information. Thus, the USERS information is displayed
2329 now in the command callback instead of in the command reply
2330 callback. The processing of the command is same as previously
2331 when server has sent the command reply in the JOINing process.
2333 * Added to USERS command in silcd/command_reply.c to join the client,
2334 we didn't use to know about, to the channel after we've created
2335 a client entry for it. Also, for clienet we did know already still
2336 check whether it is on the channel or not and add it if not.
2338 * Removed silc_server_command_join_notify as the function and its
2341 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2343 * Changed the client's pending command handling to the same as the
2344 server's pending command handling. It is also now possible to
2345 execute command reply functions from other command reply
2346 function as the function callbacks for commands and command
2347 replies are one and same. The pending commands are not static
2348 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2349 in client connection context. Thus, pending commands are server
2350 connection specific as it is convenient.
2352 Changed the function silc_client_command_pending and
2353 silc_client_command_pending_del and added new function
2354 silc_client_command_pending_check. Removed the
2355 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2358 * Added cmd_ident, current command identifier, to the client
2359 connection context in lib/silcclient/client.h to keep track on
2360 command identifiers used in command sending. Client's command reply
2361 function handling now supports the mandatory command identifiers.
2363 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2364 funtions in client to fully support pending command callbacks.
2366 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2367 as one of the arguments to the application in the command reply
2370 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2371 before first releasing SILC but came back. Now it is removed again
2372 and should come back nomore. The FORWARDED flag was used only
2373 by the JOINing procedure by forwarding the command packet to router.
2374 Now, the JOINing procedure has been changed to more generic (due
2375 to various router environment issues) and FORWARDED is not needed
2376 anymore for anything. The protocol specification is yet to be
2379 Now, removed silc_server_packet_forward from server and the flag
2380 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2382 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Renamed NAMES command to USERS command. The NAMES was named that
2385 due to historical reasons. Now it is renamed. Also, rewrote
2386 parts of the USERS command. The nickname list is not sent anymore
2387 by the server. Only Client ID and mode lists are sent in the USERS
2388 command. Changed this also to the protocol specification.
2390 The client now resolves the names and stuff after it receives
2391 the USERS list from the server when joining to the channel.
2393 * WHOIS and IDENTIFY commands has been changed to support multiple
2394 Client ID's per command. One can now search for multiple users
2395 in the network by sending only one WHOIS or IDENTIFY command.
2396 Changed the code and the protocol specifications.
2398 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2399 uses silc_server_command_whois_parse to parse the request. */
2401 * If normal server, do not parse the WHOIS and IDENTIFY requests
2402 before sending it to the router. Saves some time.
2404 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2406 * Fixed JOIN command on client library. Wrong number of arguments
2407 used to crash the client.
2409 * Added silc_server_channel_has_global function to check whether
2410 channel has global users or not.
2412 * Added silc_server_channel_has_local function to check whether channel
2413 has locally connected clients on the channel.
2415 * The silc_server_remove_from_one_channel now checks whether the
2416 channel has global users or not after given client was removed from
2417 the channel. It also checks whether the channel has local clients
2418 on the channel anymore. If it does not have then the channel entry
2419 is removed as it is not needed anymore.
2421 * The silc_server_notify now checks on JOIN notify whether the joining
2422 client is one of locally connected or global. If it is global then
2423 the channel has now global users on the channel and that is marked
2424 to the channel entry. Also, it now saves the global client to
2425 global list who is joining and JOINs it to the channel. This is
2426 for normal server, that is.
2428 Changed silc_server_send_notify_on_channel,
2429 silc_server_packet_relay_to_channel and
2430 silc_server_packet_send_to_channel check if we are normal server
2431 and client has router set (ie. global client) do not send the
2432 message to that client, as it is already routed to our router.
2434 * Implemented LEAVE notify type handling in silc_server_notify
2437 * Tested LEAVE command in router environment successfully. Tested
2438 with two routers, two servers and two clients.
2442 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2444 * Implemented SIGNOFF notify type handling in silc_server_notify
2447 * silc_server_remove_id now removes the client entry from all channels
2448 it has joined and thusly sends SIGNOFF notify type.
2450 * Rewrote the NAMES list generation in server by removing two excess
2451 loops. The lists are created now inside one loop.
2453 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2455 * silc_server_remove_channel_user checks now also global list
2456 for channel and client.
2458 * silc_server_new_channel_user checks now both local and global
2459 list for channel and client. Fixed a bug in client id decoding.
2460 Used to decode wrong buffer.
2462 * silc_server_channel_message checks now both local and global
2463 list for channel entry.
2465 * Tested channel joining (hence JOIN) in router environment
2466 successfully. Tested with two routers, two servers and two
2469 * Tested channel message sending in router environment successfully.
2471 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Added silc_server_save_channel_key into server.[ch] to save the
2474 received channel key in Channel Key payload processing. It is
2475 also used in JOIN command reply handling.
2477 Equivalent function silc_client_save_channel_key added into
2478 client.[ch] into client library.
2480 * Changed JOIN command reply to send information whether the channel
2481 was created or not (is existing already) and the channel key
2482 payload. Changed protocol specs accordingly.
2484 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2485 the request was sent by ID and not by nickname. Crashed on
2488 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2491 now correctly save the received data.
2493 * silc_server_free_sock_user_data now notifies routers in the
2494 network about entities leaving the network.
2496 At the same time implemented functions silc_server_remove_id
2497 and silc_server_send_remove_id to receive and send REMOVE_ID
2498 packets. The packet is used to notify routers in the network
2499 about leaving entities. The ID removed will become invalid in
2502 * Added function silc_idlist_del_server into server. Removes and
2503 free's server entry from ID list.
2505 * silc_server_private_message function now checks, if we are router,
2506 that the destination ID really is valid ID, naturally.
2508 * In router when NEW_ID packet is received (for new client) the
2509 hash of the Client ID is saved in the ID Cache but the
2510 client->nickname is set to NULL, instead of putting the hash
2513 IDENTIFY command now also checks that client->nickname must be
2514 valid. If it is not if will request the data from the server who
2515 owns the client. Added new function
2516 silc_server_command_identify_check.
2518 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2519 to set the command to already allocated Command Payload.
2521 * Tested private message sending in router environment with two
2522 routers, two servers and two clients. Fixed minor bugs and now
2525 * Fixed segfault from client's NAMES command. Used to crash if
2528 * Forwarded packets must not be routed even if it is not destined
2529 to the receiver. Changed server code comply with this.
2531 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2533 * Added `require_reverse_mapping' boolean value to ServerParams
2534 structure. If TRUE (not default) the server will require that
2535 the connecting host has fully qualified domain name.
2537 If the reverse mapping is not required and hostname could not be
2538 found the IP address is used as hostname.
2540 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2542 * Implemented version string checking to both client and server.
2543 The check is incomplete currently due to the abnormal version
2544 strings used in development version of SILC.
2546 * Changed all command functions in server to use the new
2549 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * Changed char *data to unsigned char *data in ID Cache system to
2552 support binary data as ID Cache data. Changed code to support
2553 binary data in lib/silccore/idcache.c.
2555 * Renamed silc_server_packet_relay_command_reply to
2556 silc_server_command_reply as it is normal packet receiving
2557 function. Rewrote the function to accept command replys for
2558 servers and not only for clients.
2560 * Mark remote router always as registered server if we are connecting
2561 to it. Otherwise, commands sent by the router to us are ignored.
2563 * All ID List find routines now returns the ID Cache Entry pointer
2564 as well if requested.
2566 * WHOIS command works now in router environment, tested with two
2567 routers, two servers and two clients.
2569 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2570 in router environment (as it is almost equivalent to WHOIS) but
2571 hasn't been tested thoroughly. Added new functions:
2573 silc_server_command_identify_parse
2574 silc_server_command_identify_send_reply
2575 silc_server_command_identify_from_client
2576 silc_server_command_identify_from_server
2578 * Disabled route cache adding because adding two different ID's with
2579 same IP replaces the old cache entry thus giving wrong route.
2580 The entry->router->connection is always the fastest route anyway
2581 so route cache may not be needed. Of course, new routes maybe
2582 established after receiving the ID when the entry->router->connection
2583 might not be anymore the most optimal.
2585 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2587 * Add route cache for received ID for fast routing.
2589 * Added silc_server_packet_route to route received packet on router
2590 that is not destined to us.
2592 * Renamed silc_server_get_route to silc_server_route_get.
2594 * Added id_string and id_string_len fields into SilcServer to
2595 include encoded ServerID for fast comparing without excess
2596 encoding of the ID's.
2598 * Cleaned up WHOIS command on server side. Added following static
2601 silc_server_command_whois_parse
2602 silc_server_command_whois_check
2603 silc_server_command_whois_send_reply
2604 silc_server_command_whois_from_client
2605 silc_server_command_whois_from_server
2607 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2608 arguments in command replies. All command functions should be
2609 updated to use this macro.
2611 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2613 * Minor typo fixes on command reply handling on server.
2615 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * Added silc_server_command_add_to_channel internal routine to add
2618 the client to the channel after router has created the channel and
2619 sent command reply to the server.
2621 * Added generic silc_server_send_command to send any command from
2624 * Use static buffer with ID rendering instead of duplicating data.
2626 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2628 * Fixed a channel user mode bug when joining to a channel server gave
2629 everybody channel founder rights, oops.
2631 * We mark ourselves as the router of the incoming server connection
2632 if we are router ourselves. This way we can check in some packet
2633 sending functions whether it is locally connected server. For
2634 incoming router connections we put NULL.
2636 * For router sending packets locally means now always sending the
2637 packet cell wide; to local clients and local servers. For normal
2638 server sending packet locally means sending it to only local
2641 * Fixed the JOIN command to really work in router environment. If the
2642 channel is created it is always created by the router. Router is
2643 also responsible of making the initial joining to the channel,
2644 sending JOIN notify to the sending server and distributing
2645 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2646 does not exist server doesn't do anything else but forward the
2647 command to the router which performs everything.
2649 * Added silc_server_send_channel_key function to send the Channel Key
2652 * Added silc_server_create_channel_key to create new channel key. The
2653 channel key is now re-generated everytime someone joins or leaves
2654 a channel, as protocol dictates. Note: channel->key_len is the
2657 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2659 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2660 packet_receive.[ch] to separate packet sending and receiving
2661 routines. The server.[ch] now includes everything else including
2662 actual packet processing (writing and reading data) and other
2665 Renamed silc_server_private_message_send_internal to
2666 silc_server_send_private_message. The routine is still though
2667 used only to relay private messages as server does not send
2668 private messages itself.
2670 Renamed silc_server_new_channel to silc_server_create_new_channel
2671 and added new function sicl_server_new_channel that handles the
2672 incoming New Channel packet. Added also new sending function
2673 silc_server_send_new_channel to send New Channel Payload.
2675 * Added new function silc_server_notify to process incoming notify
2676 packet to the server/router. Server may then relay the notify
2677 to clients if needed.
2679 * Added new function silc_server_new_channel_user to process incoming
2680 New Channel User packet. Router will redistribute the packet and
2681 send JOIN notify to its local clients and locally connected servers
2682 if needed. Normal server will send JOIN notify to its local client
2683 on same channel when received this packet. Added also corresponding
2684 sending function silc_server_send_new_channel_user to sent the
2687 * Added boolean route argument to send_notif_to_channel and
2688 packet_send_to_channel functions to attempt to route the packet
2689 if it is TRUE and send only locally if it is FALSE.
2691 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2693 * silc_server_replace_id now broadcasts the received replace ID
2694 packet if it is not broadcast packet already. The router must
2695 broadcast to inform other routers about changed ID.
2697 * Added backpointer to server's router into SilcServer context in
2698 silcd/server_internal.h.
2700 * Fixed silc_server_packet_broadcast to send correct broadcast
2703 * The channel key is now distributed to the local client as soon
2704 as it is received from the router (in router environment) so that
2705 no other packet may be sent for the channel until client has
2708 * silc_server_remove_channel_user now broadcasts the received
2709 Remove Channel User packet if it is not broadcast packet already.
2710 The router must broadcast to inform other routers about removed
2713 * Added users field into SilcPacketContext that is a reference count
2714 of the context. One can increase the reference count by calling
2715 silc_packet_context_dup which is now changed to just increase the
2716 reference count instead of duplicating the data. The reference
2717 count is decresed by calling silc_packet_context_free that will
2718 free the data after the reference count hits zero.
2720 For now on the packet context and everything allocated into it
2721 (including the raw packet from network) must be freed by calling
2722 the new silc_packet_context_free function. Added also new function
2723 silc_packet_context_alloc that must be used now to allocate the
2724 context. This also means that if a routine is asynchronous from
2725 silc_[client/server]_packet_parse_type the packet context must
2726 be duplicated by calling silc_packet_context_dup. Otherwise it
2727 gets free'd after silc_[client/server]_packet_parse_type returns.
2728 Also, one must remember that if packet is duplicated then its
2729 reference count must be decresed by calling the free function as
2730 many times as it was duplicated.
2732 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2733 from both client and server.
2735 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Made joining to a channel working in router environment.
2739 * Cleaned up JOIN command on server side and create function
2740 silc_server_command_join_channel internal routine to make the
2743 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Changed silc_command_pending list to SilcDList. Also, added
2746 `ident' field to SilcServerCommandPending structure to identify
2747 the reply and to call correct callback.
2749 Added silc_server_command_pending_check function to replace the
2750 corresnponding macro. The silc_command_pending list is not
2753 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2754 to set identifier to previously allocated Command Payload. It
2755 is used to set identifier for command when resending Command
2758 * Added silc_command_payload_encode_payload to encode Command
2759 Payload buffer from SilcCommandPayload structure.
2761 * Added silc_argument_payload_encode_payload to encode Argument
2762 payload buffer from SilcArgumentPayload structure.
2764 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Changed WHOIS command to support router connection on server side.
2767 The whois request is always sent to router unless the server is
2768 standalone server. After server has received the reply from the
2769 router will it send the reply to the client.
2771 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2772 broadcast received broadcast packet. The function is used only
2773 by router. The broadcast packet is always sent to the router's
2776 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2777 render given ID to printable string, for log files for example.
2779 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2781 * Made basic router to router connections working. At least they
2782 can now connect to each other but nothing really works the way
2783 they are supposed - yet.
2785 * Added new initiator token to RouterConnection configuration
2786 file in silcd/serverconfig.[ch]. It is used to tell whether we
2787 are the initiator to the remote router or whether we'll expect
2788 the other end to connect.
2790 * Moved registering of listener task to silc_server_init, hence
2791 the server starts listenning as soon as it is run, even if it
2792 does not have connections to other routers. Let's see how well
2795 * Changed default connection retry timeouts for more suitable in
2798 * Removed cipher and such arguments from silc_idlist_add_client
2799 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2800 Added new function silc_idlist_add_data to add the keys and stuff
2803 * Added SilcIDListData structure and added it to SilcClientEntry
2804 and SilcServerEntry as their first field in the structure. This
2805 way we can explicitly cast the ID entries to the SilcIDListData
2806 structure and get common data for the entries. In past, we had
2807 to first check what type of connection it is and then cast it to
2808 correct ID entry type. Now, we can directly cast the opaque
2809 pointer to the SilcIDListData (no matter what ID entry it actually
2810 is) and get the data needed.
2812 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2814 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2815 in some circumstances even if threre were timeout tasks, though not
2816 IO tasks, but tasks anyway. Now fixed.
2818 * Defined SilcServerConnection structure to hold connection specific
2819 stuff about directly connected servers and routers. The definition
2820 is currently in silcd/server_internal.h. I thought about having
2821 a bit more important role fro this struct but for now it is used
2822 only when connecting to other server (or router actually).
2824 * Added connecting retry support in server when connecting to
2825 router(s). The retry feature implement exponential backoff
2826 algorithm. Also, added SilcServerParams structure to hold default
2827 parameters for server. For now, it include these retry settings
2828 and are hard coded. After server is moded to be as Silc Server
2829 Library this structure will be more important.
2831 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2833 * Changed client librarys channel->clients table to SilcList and
2834 changed code accordingly.
2836 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2838 * Changed client's channel table to SilcList and changed code
2839 accordingly. Also changed SilcChannelClientEntry to include back-
2840 pointer to the channel so that client entry can use that structure
2841 as list as well and we have fast cross-reference to the channel.
2842 This change dramatically decreased the complexity of channel
2843 handling with client entry and vice versa (removed one extra
2844 loop when searching for channel entry from many functions).
2846 * Changed server->sim from table to SilcDList and changed code
2849 * NAMES command can now be used from user interface. It will show
2850 the user list on the channel, neatly.
2852 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2853 Code now saves realname of the user if it becomes available.
2855 * Renamed configure.in to configure.in.pre and made ./prepare
2856 script to automatically add correct version string to
2857 configure.in which it creates from configure.in.pre.
2859 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2861 * NAMES command reply now shows users mode with the nickname when
2864 * Moved silc_client_ch[u]mode[_char] functions from
2865 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2866 place sucks, they are utility functions and should be in some
2869 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2871 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2874 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Added TRQ (efficient deque and list library) into lib/trq. This is
2879 a very good list library that is currently used in the SILC. Defined
2880 SilcList API over the library because I didn't like the API very
2881 much. See lib/trq/silclist.h for the API and examples of how to
2882 use the API. Fixed various places in the code to use the new
2883 SilcList API. The SilcList is meant for lists that has a structure
2884 already defined as a list. It is not suitable to add just some
2885 context to the list (in TRQ, the context is the list actually).
2887 So, I defined SilcDList that can be used for the purpose where
2888 predefined list structure does not exit. This can be used as
2889 such list. Now some context just can be added to the SilcDList.
2890 Currently this list is not used in the SILC just yet, though there
2891 are a lot places where this can replace dynamically allocated
2892 tables and I will fix these places, later, to use SilcDList.
2893 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2894 and use TRQ internally).
2896 Also fixed some annoying warning messages that the original TRQ
2897 code generated. Also minor changes to TRQ's Makefile.in.
2899 * Added support for querying by Client ID to both WHOIS and
2900 IDENTIFY commands into server, as required by the protocol.
2902 * Removed method function pointers from SilcBuffer structure. They
2903 weren't used to anything and just increased the context size for
2904 no good reason. This change also made silc_buffer_alloc and
2905 silc_buffer_free functions inline functions.
2907 * Disabled command flooding detection support until it's fixed so
2908 that it accepts commands in but does not execute them more than once
2911 * Added silc_net_localhost(), to return local hostname, into
2912 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2913 that must be initialized before calling silc_client_init.
2915 * Added new function: silc_server_send_notify_on_channels to send
2916 notify messages to all channels client has joined. It is assured
2917 that the message is sent only once per client.
2919 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2920 lib/silcutil/silcutil.[ch] as silc_format function. The new
2921 function is generic and is used by server as well, not only by
2922 the logging routines.
2924 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2925 the provided version string was not acceptable. Added new function:
2926 silc_ske_check_version into lib/silcske/silcske.h. The function
2927 must be implemented by the application (client or server) and it
2928 does not reside in the SKE library. The function checks the version
2929 string remote end sent.
2931 * Added back pointers (to opaque context and to SilcSocketConnection)
2932 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2934 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2935 duplicate packet context structure.
2937 * Changed `notify' client operation to send same arguments as client
2938 receives from server except for ID's. ID's are mapped to correct
2939 ID entry and that is returned. Also, if channel entry is not sent
2940 by server but the notify is for channel the channel entry is sent
2941 to application (otherwise application doesn't know that it is for
2942 channel (library gets it from packet's Destination ID)).
2944 * Added silc_client_remove_from_channels into client library to
2945 remove a client from all channels it has joined to. Used when
2946 received SIGNOFF notify from server. Added also new function
2947 silc_client_replace_from_channels to replace old ID entry with
2948 new ID entry on all channels. Used when received NICK_CHANGE
2951 * Fixed ID Cache list handling in silc_idlist_get_client in
2952 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2953 to get (or query) client by ID.
2955 * Updated TODO list.
2957 * Added connection authentication status message defined by the
2958 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2959 support for these into the code in client and server side.
2961 * Added generic function silc_client_send_command to send any command
2962 with variable argument list. Application should use this function
2963 to send commands if the command functions provided by the library
2964 does not suite for the application's user interface needs.
2966 * Added new `failure' client operation. Application is notified about
2967 received failure packet if client is executing a protocol. In this
2968 case the protocol's execution has failed.
2970 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2971 is required by the protocol.
2973 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2974 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2977 * Added status flag to SilcSKE object to indicate realtime status
2978 of the SKE protocol.
2980 * Application receives now exactly same command reply arguments as
2981 the library receives from server. However, if ID is received the
2982 corresponding ID entry is returned to the application (eg. Client
2983 ID is mapped to correct SilcClientEntry entry and that is returned).
2984 Changed command_reply client operation due to this change.
2986 * Changed all ID's in commands and in command replys as ID Payloads.
2987 Change affected both client and server side codes.
2989 All ID's sent in SILC network (with execption of ID's in SILC
2990 Packet header) are sent in ID Payload to support variable length
2993 * Server now notifies nick changes and notifies all clients on
2994 the channels about the new nickname (about the new Client ID,
2997 * Implemented CMODE command to change channel modes. Supports all
2998 channel modes defined by the protocol specs except ban and invite
2999 lists. (Also, private channel key mode is supported but support for
3000 setting private channel key in client is missing, thus, this mode
3001 has no effect on client side (except that server requires that the
3002 client uses private channel key and normal channel traffic does not
3005 Also, invite mode works per se, but INVITE command does not work
3006 yet correctly, so you can set channel as invite only channel but
3007 inviting clients to the channel does not work (it is yet to be
3008 thought what's the best way to do it).
3010 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3011 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3012 Implemented CUMODE command to change user's mode on the channel.
3013 Supports all modes defined by the protocol specs.
3015 * Added NAMES command reply to return users modes on the channel.
3017 * Removed unnecessary and slow ciphers from lib/silccrypt.
3019 * Set SO_KEEPALIVE option to connection sockets by default.
3021 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3023 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3024 redefined the Notify Payload into protocol specs.
3026 * Added silc_id_payload_parse_id to get ID directly from raw
3029 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3032 accept searching by Client ID as well.
3034 * Added support for LEAVE and SIGNOFF notify types in client library.
3036 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3037 to parse ID Payload from raw data.
3039 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Added flags parameter into silc_ske_assemble_security_properties
3042 function in lib/silcske/silcske.[ch].
3044 * Changed notify client operation to fit better for notify messages
3045 sent by server. The notify payload received from server is now
3046 passed to the application (after parsing it to SilcNotifyPayload).
3047 It is application's responsibility to retrieve the arguments
3048 from the payload and show the message the way it wants. The message
3049 sent by server is implementation specific.
3051 * Changed public keys to comply with the protocol specification.
3052 Old public keys are not supported anymore and are not compatible.
3054 * Removed nickname from Channel Payload as the latest draft removed
3055 it. The client must resolve the nickname from the NAMES command
3056 reply received when it joined the channel.
3058 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3060 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Fixed some errors in protocol specification drafts.
3064 * Created lib/silccore/silcnotify.c to implement Notify Payload
3065 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3066 generic payloads described by protocol specifications. The file
3067 includes implementations for ID Payload and Argument Payload.
3069 * Changed Command Payload implementation to use the new Argument
3070 Payload. Changed command_xxxx_payload to command_payload_xxxx
3071 to comply with SILC coding conventions.
3073 * Added suppport for Argument Payload handling in Notify Payload
3074 implementation as protocol requires it. Added the new support
3075 into server and client lib as well.
3077 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Added support for multiple nicknames on same channel. [n] is
3080 added locally to the nickname if there are more than one same
3081 nicknames on the channel.
3083 * Server now sends all nicknames that matched WHOIS request.
3084 Client also shows the list received from server.
3086 * Added TOPIC command to client side. User can now set and show
3087 current topic on channel.
3089 * Added MOTD command to client and server. Also, server sends the
3090 motd when client connects to the server.
3092 * Changed version strings to comply ISO 8601.
3094 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * Fixed protocol error handling in client library. It should now
3097 cope even if the SKE fails for some reason.
3099 * Made new protocol specification drafts for submitting to IETF.
3101 * Implemented TOPIC command to server in silcd/command.c.
3103 * Added two new notify types into lib/silccore/silcnotify.h:
3104 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3105 notify nickname change and topic setting/change on a channel.
3107 * API change of command_reply operation in client library. The
3108 application gets now the status type received from server as well.
3110 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3114 * Cras fixed and optimized the packet handling even further and
3115 it should work now. Minor change to the prototype of function
3116 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3118 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Added new function into lib/silcutil/silcschedule.[ch]:
3121 silc_schedule_with_fd to select() a specified fd. The function
3122 returns after timeout expires or data arrives or goes. The
3123 function is used by packet routines to wait that all data is
3124 received from network.
3126 * Fixed data reading from network in lib/silccore/silcpacket.c.
3127 The code now assures that all data is read from the fd and then
3128 continues packet processing. This was a bug fix since the code
3129 used to drop some data in some circumstances.
3131 * Added new function into lib/silcclient/client.[ch]:
3132 silc_client_start_key_exchange to start key exchange after
3133 connection has been established to server. The code internally
3134 now uses this funtion but its main purpose was to provide it
3135 for applications that perform their own connecting. After
3136 application has created a connection it merely calls this
3137 function to start the key exchange between client and server.
3138 The library takes care of everything else after that.
3140 Updated also lib/silcclient/README to explain the usage of
3143 * Do not send to application information that connection has
3144 been established. Application gets notified it by connect
3147 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3149 * Applied cras's patch to add silc_schedule_one function. The
3150 function runs scheduler once and returns.
3152 * Fixed the scheduler after cras messed it up. The timeout
3153 handling works now as it's supposed to work.
3155 * Added into lib/silccore/ silcnotify.h to include notify
3156 message types support. Changed silc_server_send_notify*
3157 functions, in server.[ch], to support those new notify types.
3158 Added the support for the notify types into client library,
3159 as well. Added new notify client operation into ops.h in
3162 * Changed silc_server_packet_send_to_channel to send normal
3163 packets instead of just channel message packets. The function
3164 is now used to send the notify packets to channels. It is not
3165 used to send channel message packets anymore, as server never
3168 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3169 va_arg()s as it seems to require it nowadays. I guess, if SILC
3170 is compiled with older va_arg() the new code should work anyway.
3172 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Splitted core library. Core library (lib/silccore) includes
3175 now only SILC protocol specific core (and common) components.
3176 Created new utility library (lib/silcutil) that includes more
3177 generic purpose stuff. The stuff for util library was taken
3178 from the old core library. This was minor and easy split.
3180 * Created SILC Client Library (lib/silcclient) that includes
3181 implementation of the SILC client without user interface. This
3182 was major move from silc/ directory. The code has been changed
3183 so that it is transparent towards the user interface. The
3184 silc/ directory includes now the same user interface as before
3185 and it uses the new client library. Read lib/silcclient/README.
3186 Basicly, the client library performs everything else related
3187 to SILC except user interface handling. Also, configuration
3188 files are considered to be part of user interface and library
3189 does not handle them.
3191 This change also changed a lot of structures, function naming etc.
3192 Most important change was that SilcClientWindow object was
3193 renamed to SilcClientConnection in the client library. Created
3194 also new file lib/silcclient/ops.h. Also added new files
3195 silc/local_command.[ch] and silc/client_ops.[ch].
3197 All these changes were made to make it easier for user interface
3198 designers to create what ever user interface for the SILC client
3201 It is also expected that the server will be moved to lib
3202 directory as well and SILC Server Library will be created;
3203 sometimes in the future.
3205 * Removed Local commands from lib/silccore/silccommand.h as
3206 they are application specific and new client library does not
3207 handle any of those anymore.
3209 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3210 old client implementation in silc/.
3212 * Added support for callback functions in SILC_LOG_* macros.
3213 Application can now set its own callbacks that will be called
3214 instead of using the default functions that will always print
3215 the debug messages to stderr (or stdout). Also, debugging can
3216 now be disabled by setting silc_debug to FALSE and re-enabled by
3217 setting it to TRUE. Note, that logging will still work even
3218 if debugging is disabled.
3220 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3221 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3222 silc_log_reset_debug_callbacks.
3224 * To enable debugging in silc client one must give now -d
3225 option on command line.
3227 * Changed silc_schedule_init to automatically allocate task queues
3228 if they are not allocated before calling it.
3230 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3232 * Added GMP 3.1 into math library.
3234 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3236 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3237 a channel in SILC network. The packet is used by servers and
3238 routers to notify other routers that user has left a channel.
3239 This little feature was missing until now. Added the feature
3240 to protocol specification as well.
3242 Added functions: silc_server_send_remove_channel_user and
3243 silc_server_remove_channel_user into server.[ch].
3245 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3246 lib/silccore/silcpacket.h. However, they are not implemented
3249 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3251 * Fixed joining to a channel and sending channel messages
3252 between server and router. The channel message sending should
3253 now work inside a cell.
3255 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3257 * Fixed the private message sending between server and router.
3258 The private message sending should now work inside a cell.
3260 * Added silc_server_replace_id into server.[ch] to replace
3261 existing ID in the SILC network.
3263 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3264 and silc_idlist_replace_server_id into idlist.[ch] in server.
3266 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Fixed the server to server connections. Server can again now
3269 connect to router. Router to router connections probably does
3272 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3274 * Added dynamic protocol registering support. Now protocols can
3275 registered and unregistered on the fly. Patch by cras.
3277 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Added lib/contrib directory to hold routines that some platforms
3280 don't have but are needed by SILC.
3282 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3283 into lin/contrib to provide getopt() and getopt_long() for
3284 those who don't have it.
3286 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3288 * Added AWAY command to client. When away message is set and
3289 client receives a private message packet the client automatically
3290 replies to the sender with the away message.
3292 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3293 bug seemed to be the cause of recent problems when compiling
3296 * Added version detection support to SKE protocol specification
3297 and added the new changes to the SKE implementation as well.
3298 There were other minor changes in the SKE protocol as well.
3300 Many changes in lib/silcske/silcske.[ch] and in
3301 lib/silcske/payload.[ch].
3303 * Added ^U functionality, clear input line. Patch from cras.
3305 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Mainly small bugfixes on core library. Fixed some debugging
3308 logging and buffer overflow in silclog.c.
3310 * Updated config.sub and config.guess on the distribution tree.
3312 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Added command lagging support in server. Client may execute
3315 commands now only once in two seconds.
3317 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Optimized packet reception. MAC computation and checking is now
3320 also more optimized. A lot previously duplicated code is now
3321 used as generic by both client and server.
3323 * Fixed key pair generation in clientutil.c
3325 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Added into lib/silccore/silcbufutil.[ch] new function;
3328 silc_buffer_realloc.
3330 * Moved generic packet sending/encryption functions to
3331 lib/silccore/silcpacket.[ch] from client and server. Some
3332 rewriting of the functions.
3334 * Moved all generic packet reception/decryption functions to
3335 lib/silccore/silcpacket.[ch] from client and server. The
3336 packet processing is now much cleaner in both client and server.
3337 These were major changes in both client and server.
3339 * Created many common functions in server to do packet sending.
3340 Previously code were duplicated a lot, this has been removed
3343 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Rewrote major parts of the ID cache system. Don't know
3346 whether it is better now or not but at least the API is more
3349 * Major rewrite on ID cache stuff on client because of the ID
3350 cache API changes. Added idlist.c to client.
3352 * Also major rewrite on ID cache stuff on server as well.
3353 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3354 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3355 in hand, instead they are all put into the ID cache system now.
3356 All server_idlist_* routines uses ID cache now instead of
3357 traversing its own lists (those lists does not exist anymore).
3358 SilcIDList though still exists. Also, SilcXXXEntry's are
3361 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Finally made the SKE implementation compliant to the protocol
3364 specification. All mp integers are now binary encoded as
3365 opposed being HEX encoded.
3367 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3370 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3371 functions: silc_[encode/decode]_pem. Also added function
3372 silc_encode_pem_file to PEM encode with newlines ('\n') for
3375 * SILC public keys are now encoded either PEM or binary. Same
3376 option is for private keys as well. By default private keys
3377 are binary encoded and public keys PEM encoded. Silly HEX
3378 encoding were removed.
3380 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3381 function to create fingerprints.
3383 * Fixed a bug in SHA1; does not change the original data anymore.
3385 * Partly implemented INFO command on client and server side.
3386 Fixed CLEAR command. Changes to SERVER command; show current
3387 server(s) when giving command without arguments. Added
3388 VERSION command to client.
3390 * Added check to server that unregistered connections cannot
3391 execute commands (unless it is specificly allowed).
3393 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * Fixed screen refresh.
3397 * Fixed channel joining bug from client. On some circumstances
3398 client tried to join to a channel it had already joined.
3400 * Added public key verification process into client's protocol.c.
3401 The client now verifies the public key from user and saves
3402 it into ~./silc/serverkeys/ directory.
3404 Added into: clientutil.[ch]: silc_client_verify_server_key.
3406 * Changed SKE protocol's silc_ske_initiator_finish function
3407 to accept callback function that verifies the received public
3408 key. Removed old silc_ske_verify_public_key function.
3410 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3413 silc_pkcs_private_key[_data]_set.
3415 * Made the password and public authentication more cleaner in
3416 server's protocol.c.
3418 * Removed historic and obsolete protocol `channel_auth' from
3419 both client and server.
3421 * Removed wrong way of sending command status messages from
3422 server to client in server's command.c. The old way violated
3423 protocol specification.
3425 Changes to silccore/silccommand.[ch]: removed
3426 silc_command_encode_status_payload -> not needed anymore,
3427 changed silc_command_encode_payload_va to accept extra
3428 argument on variable argument list. The argument type must
3429 now be provided to the function. Also, added new function:
3430 silc_command_encode_reply_payload_va which is same as
3431 normal command_encode_payload_va except command status type
3432 is provided as extra argument.
3434 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Added ~./silc directory handling. The directory includes the
3437 public and private keys for the client.
3439 Added silc_client_check_silc_dir, silc_client_create_identifier
3440 and silc_client_load_keys.
3442 * Implemented SILC protocol compliant public key. Added public
3443 and private key saving to and loading from files.
3445 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3446 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3447 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3448 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3449 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3451 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3452 silc_pkcs_load_[public/private]_key.
3454 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3456 * Added silc_server_get_route (route.[ch]) to get connection
3457 data for the fastest route for given ID.
3459 * Implemented INVITE command on client and server. The command
3460 were re-defined in the SILC Protocol Specification and the
3461 implementation now complies with the specification.
3463 * Implemented PING command on client and server.
3465 * Implemented NAMES command on client and server. The server side
3466 supports currently only normal server not router server yet.
3467 Some changes to NAMES definition in SILC protocol specification.
3469 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Implemented LEAVE command on client and server.
3473 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3474 again. This change was made to the protocol as well. Server
3475 should not violate the protocol specification anymore.
3477 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3480 was tested. SOCKS4 was not but should work anyway.
