1 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Register default ciphers and stuff when using the -S option
4 in the client. Affected file silc/silc.c.
6 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Fixed the silc_verify_public_key client operation function to
9 save the public keys differently. The fingerprint is now
10 used as filename and not the hostname. This way also the
11 client keys are saved uniquely and not with hostnames. The
12 affected file is silc/client_ops.c.
14 * Trimmed the silc_hash_fingerprint function to remove extra
15 whitespaces from the end of the fingerprint. The affected
16 file is lib/silccrypt/silchash.c.
20 * Added silc_cipher_register_default function to register all
21 default ciphers. It can be used when configuration files
22 does not exist and the application does not want any specific
23 ciphers in any specific order.
25 The SilcDList is now used as silc_cipher_list dynamically
26 allocated cipher list. Removed the static list all together
27 and now all ciphers must be allocated to the dynamic list.
28 The silc_cipher_alloc routine was changed to check only the
31 All silc_cipher_* routines that used to return int returns
34 The affected files lib/silccrypt/silccrypt.[ch].
36 * The same thing was done to silc_hash_* as for silc_cipher_*
37 routines. Affected files lib/silccrypt/silchash.[ch].
39 * The same thing was done to silc_pkcs_* as for silc_cipher_*
40 routines. Affected files lib/silccrypt/silcpkcs.[ch].
41 Added also silc_pkcs_[un]register[_default] functions.
42 Removed the data_context from the PKCS API.
44 * Added silc_hmac_register_default function to register default
45 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
46 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
47 to unregister all hmacs at once.
49 * Register the default ciphers, hash functions, PKCSs and HMACs
50 if client's configuration file does not exist. The affected
53 * The client did not load the hash functions from the SIM
54 modules at all. Added support for this. Affected file is
57 * When decoding public key with silc_pkcs_public_key_decode, check
58 the supported algorithm only if PKCS are registered. Affected
59 file lib/silccrypt/silcpkcs.c. The same was done with the
60 silc_pkcs_private_key_decode.
62 * Fixed the SILC List routines to keep the list always in order.
63 It used to change the list's order when traversing the list but
64 not it preserves the order. Affected file lib/trq/silclist.h.
66 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
68 * Added the client library to use the SilcSocketConnection's
69 reference counter (by silc_socket_dup) to prevent the bug that
70 the socket object may be freed underneath async operation.
72 * The name resolv library checking fixes in the configure.in.pre.
75 * Created new version of the protocol drafts for future
76 development. The -03 drafts are the ones that will be changed
77 in the trunk now and the -02 will remain as they are.
79 * Send list of CUMODE notifys to the router when announcing
80 the channel users to the router. Affected file silcd/server.c.
81 If the router receiving channel founder CUMODE for a channel
82 that already has channel founder it will send CUMODE notify
83 to the sender to remove the channel founder rights from the
84 announced client. Affected file silcd/packet_receive.c.
86 * The CUMODE notify may now use Server ID as well as the entity
87 who changes the mode. Updated protocool specs.
89 * Updated INSTALL and README files.
91 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
93 * New web pages in the http://silc.pspt.fi. The pages was
98 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
100 * Implemented the [DenyConnectin] config section in the server.
101 Added silc_server_config_denied_conn to check whether incoming
102 connection is denied. Affected file silcd/serverconfig.[ch].
104 * Do not check the ports when checking the incoming configuration
105 data if the port is 0, meaning any. Affected file is
106 silcd/serverconfig.c.
108 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
110 * Fixed buffer overflow in silc_string_compare in the file
111 lib/silcutil/silcutil.c.
113 * Fixed double free in silc_server_command_leave in the file
116 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
118 * Fixed the version checking in the server. Affected file is
121 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
123 * Fixed the configuration data fetching when accepting new
124 connections in the server. Affected file silcd/server.c.
126 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
128 * Added `sender_entry' argument to the function
129 silc_server_packet_relay_to_channel so that we can check
130 whether some destination actually belongs to the same route
131 the sender belongs (ie, we must not resend the packet to the
132 sender). Affected file silcd/packet_send.[ch].
134 * Added `servername' field to the SilcClientEntry in the server
135 to hold the name of the server where client is from. Affected
136 file is silcd/idlist.h.
138 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
140 * Moved the channel message encrypting in the router betwen
141 router connections from silc_server_channel_message to the
142 silc_server_packet_relay_to_channel since we want to check
143 whether we have anybody channel before encrypting anything.
144 Affected files silcd/packet_[receive/send].c.
146 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Fixed the [AdminConnection] server config section to support
149 multiple entries. Affected file silcd/serverconfig.c.
151 * Added support into the server to check the validity of the
152 incoming connection before executing any KE or authentication
155 * The connection configuration is now saved to the KE and
156 connection auth protocol contexts and not fetched anymore in
157 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
159 * The local hosts listenning address and port is also resolved
160 now when starting the server. We want to have the socket object
161 to include the real address and port for the listener. Added
162 new function silc_net_check_local_by_sock into the files
163 lib/silcutil/silcnet.[ch].
165 * Fixed a broadcast bug in server -> do not broadcast if we
168 * Fixed a routing bug. Do not route broadcast packets ever.
169 Broadcast packets must be processed always and not routed since
170 they may be destined to some other host than yourself and thus
171 would get routed without no good reason. Affected file is
174 * Added function silc_server_config_is_primary_route to check
175 whether primary router connection has been configured (a router
176 configuration that we are initiating). If there is not, we
177 will assume that there is only two routers in the SILC network
178 and we will use the incoming router connection as our primary
179 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
181 * Changed the order of the broadcasting. Broadcast _after_ the
182 packet has been processed not before. Affected file is
185 * Fixed a [ClientConnection] parsing bug. The port was never
186 parsed correctly thus resulting to port 0. Affected file
187 silcd/serverconfig.c.
189 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
190 argument and did not set the broadcast packet flag. Affected
191 file silcd/packet_send.c. Fixed same bug in the function
192 silc_server_send_notify as well.
194 * If we receive NEW_ID packet for our own ID in the server, ignore
197 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
201 * Removed the nickname from the Private Message Payload.
202 Updated the code and the protocol specs.
204 * Updated protocol specs for submitting to the IETF.
206 * Tweaked the Random Number Generator a bit. Affected file
207 lib/silccrypt/silcrng.c. Exported a new function
208 silc_rng_[global]_add_noise which can be used to add more
211 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
213 * Do not parse packets with different timeout when protocol
214 is active -> may cause problem with rekey. Affected file
217 * When server receives signoff notify it must not create
218 new channel key if the client is on any channels since the
219 sender of the signoff notify will create it.
221 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
223 * Added printing of error messages during SKE protocol from the
224 failure packet sent by server during SKE. Affected file
227 * Removed the client's failure_callback handling with timeout
228 and handle it immediately when received.
230 * The SKE library returned wrong type in SUCCESS and FAILURE
231 packets. They must be 32 bit MSB not 16 bit MSB.
233 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
235 * Ok, rewrote the logic of the re-key and now it seems to work.
236 I tested it on high traffic with frequent re-keys without
237 problems. Added hmac_receive (and renamed hmac to hmac_send)
238 in SilcClientConnection in lib/silcclient/client.h and
239 in SilcIDListData in silcd/idlist.h. Also, removed the
240 SilcPacketParserContext's cipher and hmac fields as they are
241 not needed anymore and actually caused some problems when
242 the ciphers and hmac's changed underneath the packet parser.
244 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
246 * If re-key protocol is active then process the incoming packets
247 synchronously since we must assure that icoming packets encrypted
248 with the old key is processed before the new keys is set to
249 use. This is true other packets than for REKEY packets.
250 Affected file silcd/server.c. The same was done to client library
251 as well, affected file lib/silcclient/client.c.
253 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
255 * Fixed bug in client and server to accept the force send if
256 the packet is send from silc_[server/client]_packet_process
257 function. Otherwise the packets are never delivered, oops.
259 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
261 * Disable force sending of packets when REKEY protocol is active.
262 We must assure that no packet is sent directly when rekey is
263 performed. All packets must be sent through packet queue.
264 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
265 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
266 function is silc_[server/client]_packet_send_real to check
269 * Replaced the SIM paths from example config files to
270 /usr/local/modules. Also, make install creates now
271 /usr/local/silc/logs directory to hold all the SILC server
274 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
276 * Made the configure.in.pre work on Solaris. Patch by salo.
278 * Made all ciphers compatible with non-x86 machines. Defined
279 CBC mode macros into lib/silccrypt/ciphers_def.h.
281 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
283 * Fixed the make install.
285 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
287 * When MAC computation fails the silc_packet_decrypt returned 0
288 even though it was supposed to return -1. Fixed this. The
289 affected file is lib/silccore/silcpacket.c.
291 * Do not replace the config files in /etc/silc (in make install)
292 if they already exist. Affected file ./Makefile.am.
294 * Do not send re-key packets immediately but through packet queue.
295 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
297 * Changed silc_net_check_host_by_sock to return FALSE if the
298 IP/DNS could not be resolved. Though, it returns the IP address
299 now even if it could not resolve it (but returns also FALSE).
300 Affected file lib/silcutil/silcnet.[ch].
302 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
304 * Added silc_pkcs_decode_identifier to decode the public key's
305 identifier. Affected file lib/silccrypt/silpkcs.[ch].
306 Added also silc_pkcs_free_identifier. Added also new context
307 SilcPublicKeyIdentifier.
309 * Added -S option to the silc client. It is used to dump the
310 contents of the specified public key file.
312 * Changed the PKCS api to return the public key length when
313 setting the public key.
315 * Fixed a fatal bug in the public and private key file loading.
316 Affected file lib/silccrypt/silcpkcs.c.
318 * Execute the packet parsing for client with zero (0) timeout
319 if the protocol is active. Affected file silcd/server.c.
321 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
323 * Made the key generation options to the silcd program. Added
324 -C option, equivalent to client's option.
326 * Added new [ServerKeys] config section to the server. It
327 configures the server's public and private key.
329 * Defined generic Public Key Payload into the protocol
330 specification to send specific type of public keys and
333 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
334 public key or certificate.
336 * Implemented the GETKEY command to the server and to the
337 client library and on user interface.
339 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Made preliminary `make install' work.
343 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
345 * Added SilcServerRekey context into silcd/idlist.h.
347 * Added the PFS support as defined in the specification to the
348 SKE protocol. Affected files lib/silcske/*.c.
350 * Added `ske_group' field to the SilcServerRekey context to hold
351 the number of the SKE group that is used with PFS in re-key.
352 Affected file silcd/idlist.h.
354 * Added PFS re-key support to the server. Affected file is
357 * Added silc_protocol_cancel to cancel execution of the next
358 state of the protocol. Affected file is
359 lib/silccore/silcprotocol.[ch].
361 * Added the re-key support with and without PFS to the client
362 library. Re-key is performed once in an hour, by default.
364 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
365 Added silc_client_rekey_callback and silc_client_rekey_final.
366 Affected files are lib/silcclient/protocol.[ch] and
367 lib/silcclient/client.[ch].
369 * Removed the `hmac_key' and `hmac_key_len' fields from the
370 SilcClientConnection structure; not needed. Affected file is
371 lib/silcclient/client.h.
375 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
377 * Do not ask whether user wants to use the negotiated private key
378 for private messages, just use it. Affected file is
379 silc/local_command.c.
381 * Added `send_enc_key' and `enc_key_len' fields to the
382 SilcIDListData structure since they are needed in the re-key
383 phase. Affected file is silcd/idlist.[ch].
385 * Implemented the simple re-key protocol into the server.
386 Affected files silcd/server.c and silcd/protocol.[ch]. The
387 re-key will be performed once in an hour, by default.
389 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
390 Added silc_server_rekey, silc_server_rekey_callback and
391 silc_server_rekey_final.
393 * Removed Tunneled flag from the protocol. Updated the code
394 and the specifications.
396 * Adde `pfs' field to the SilcIDListData to indicate whether
397 the PFS is to be performed in the re-key. Affected file is
400 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
402 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
403 int64 of at least the xintXX size. If void * is less that 4
404 bytes uint32 * will be used. Defined bool as boolean.
406 * Changed _ALL_ unsigned long and unsigned int to uint32,
407 unsgined short to uint16 in the source tree.
409 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
410 not handle clients that has entry->data.registered == FALSE.
411 They are not in the network anymore. Affected file is
414 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
416 * Implemented the sending of the SERVER_SIGNOFF notify in the
417 server. Affected file is silcd/server.c.
419 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
420 Added also silc_notify_payload_encode_args into the
421 lib/silccore/silcnotify.[ch].
423 * Implemented ther SERVER_SIGNOFF notify handling in the server.
424 Affected file silcd/packet_receive.c.
426 * Implemented the SERVER_SIGNOFF notify handling in the client
427 library. Affected file lib/silcclient/client_notify.c. Also,
428 implemnted the printing of the SERVER_SIGNOFF info to the
429 application. Affected file silc/client_ops.c.
431 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
432 if the deleting was successful. Affected file silcd/idlist.[ch].
434 * Added support for public key authentication in the connection
435 authentication protocol in the client library. Affected file
436 lib/silcclient/protocol.c.
438 * Changed the server's silc_idlist_get_clients_by_* interface
439 to support already allocated array so that new entries may be
440 added to pre-allocated array. Affected file silcd/idlist.[ch].
441 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
444 * All command reply functions in the server now calls the
445 pending command callback even if error occured. This way the
446 error will be delivered to the client as well. Affected files
447 silcd/command.c and silcd/command_reply.c.
449 * Fixed INFO command to return local server's info if no server
450 was provided. Affected file lib/silcclient/command.c.
452 * Removed RESTART command for good. Updated the code and the
455 * Rewrote parts of the task system. It is a bit simpler now.
456 Removed unsued task priorities. The affected files are
457 lib/silcutil/silctask.[ch].
459 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
461 * Moved the USERS printing from the library to the application.
462 Affected files lib/silcclient/command.c and silc/client_ops.c.
464 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
468 * Added channel key re-key support. The re-key is perfomed
469 only by the router and is done once in an hour. Added `rekey'
470 field to the SilcChannelEntry in the server. Affected files
471 silcd/server.c and silcd/idlist.h.
473 * Added silc_task_unregister_by_context into the file
474 lib/silcutil/silctask.[ch].
476 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
478 * Added SILC_UMODE_GONE mode to indicate when the client is not
479 present in the SILC network. Added also support to the local
480 command AWAY that will set this mode. Added support of showing
481 "xxx is gone" in WHOIS command. The USERS command shows the
484 * Fixed setting server and router operator privileges in the
485 server's UMODE command. Affected file silcd/command.c.
487 * Merged the SKE KE1 and KE2 payloads into one payload. The
488 new KE payload is equivalent to the old KE2 payload.
490 Cleaned up the SKE Start Payload parsing. It now uses the
491 simple buffer unformatting to do the parsing. A lot faster
494 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
495 to the SKE that is used to indicate whether both of the SKE
496 parties should perform authentication. By default only the
497 responder performs authentication. By setting this flag also
498 the initiator must do authentication. By default it is unset
499 since in normal SKE case, client to server connection, only
500 the responder should do authentication. When doing SKE between
501 two clients both should perform authentication. Updated the
502 code and the protocol specs.
504 * A little fix to IDENTIFY command in the server. Search the
505 client first by hash not nickname. Affected file is
508 * Fixed the silc_client_close_connection to support closing
509 the client to client connections wihtout deleting too much
510 data. Affected file lib/silcclient/client.c.
512 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
513 are received if protocol used to be active but is not anymore
514 the application would crash due to NULL pointer dereference.
515 Affected files silcd/server.c and lib/silcclient/client.c.
517 * Added `hash' field to the SilcClientConnection to include
518 the hash function negotiated in the SKE protocol.
520 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
521 to set the channel founder authentication data. A client can
522 claim the founder rights later by providing the authentication
523 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
524 This way the channel founder can regain the channel founder
525 privileges even it is left the channel. This works only on
526 local server and the client must be connected to the same
527 server to be able to regain the founder rights. Updated the
528 protocol specs accordingly.
530 Added support to the CMODE command in the client to set the
531 founder auth data. Read the README to see how to set it.
533 Added support to the CUMODE command to claim the founder
534 rights. Read the README to see how to do it.
536 Added support for the founder authentication to the Channel
537 Entry in the server. Affected file silcd/idlist.h.
539 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
540 server's CMODE command. Affected file silcd/command.c.
542 * Added the following new functions into lib/silccore/silcauth.[ch]:
543 silc_auth_get_method and silc_auth_get_data.
545 * The server now saves the remote hosts public key to the
546 SilcIDListData pointer. Affected file silcd/protocol.c.
548 * The normal server now does not remove the channel entry from
549 the cache if the founder authentication data is set. It used
550 to remove it if the founder was the last one on the channel on
551 the server and left the channel. The auth data is saved and
552 if the channel is re-joined later the old entry is used with
553 the old auth data. Affected files silcd/command_reply.c and
556 * Removed the `pkcs' field from the SilcIDListData structure
557 in the server; it is not used. Affected file silcd/idlist.h.
559 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
561 * Fixed packet processing on slow links. Partial packets were
562 never re-processed because the incoming data buffer was cleared
563 by the application. Application must not directly clear the
564 sock->inbuf, the packet processing routines handle it. Fixed
565 this in client library and in server.
567 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
569 * Fixed the WHOIS and IDENTIFY send reply function to really
570 check whether to send list or just one entry. Affected file
573 * Cleaned up the LEAVE command's channel key distribution. The
574 affected file silcd/command.c.
576 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
577 can enforce the channel mode as well. In that case the ID
578 includes the ID of the server. The code now enforces the
579 mode change if the router have different mode than the server.
581 * The notify client operation with CMODE_CHANGE notify can now
582 return NULL client_entry pointer if the CMODE was not changed
583 by client. Application must check for this.
585 * Added <Server ID> argument to INFO command to support server
586 info fetching by Server ID.
588 * Added silc_server_announce_get_channel_users to get assembled
589 packets of channel users of the specified channel. Affected
590 file silcd/server.[ch].
592 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
593 was freed underneath the ID Cache.
595 * Re-announce clients when the server received CHANNEL_CHANGE
596 notify from the router. Affected file silcd/packet_send.c.
598 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
600 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
601 crashed since it did not handle the fact that there is no cipher
602 called "3" and didn't check the error condition. Now fixed.
604 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
605 flag. It can be used to send message requests.
607 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
609 * Implemented the RESTART command in the client.
611 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
612 notice type messages. Added notice printing to the user
615 * The channel keys are not re-generated if the channel's mode
616 is PRIVKEY, ie private key on the channel exists. Affected
617 files silcd/server.c and silcd/command.c.
619 * Fixed a little bug in channel message delivery when channel
620 private keys are set in the server. Affected file is
623 * Changed the setting on channel->on_channel = TRUE from the
624 silc_client_save_channel_key to the JOIN command reply. The
625 key payload is not received if the private channel key is set.
626 Affected file lib/silcclient/command_reply.c and the
627 lib/silcclient/client_channel.c.
629 * When the CMODE_CHANGE notify is sent and the channel private
630 key mode is removed the channel key must be re-generated in
631 other cells as well. Added this support for the router in the
632 silcd/packet_receive.c.
634 * Added new local command NOTICE to send notice message on
635 channel. Affected file silc/local_command.[ch].
637 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
639 * Added new local command ME to the client. It is used to send
640 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
641 some action. Affected file silc/local_command.[ch].
643 * Changed channel_message and private_message client operations
644 to deliver the message flags to the application. Added also
645 the `flags' arguments to the silc_client_send_channel_message
646 and silc_client_send_private_message functions. Affected file
649 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
651 * Redefined the Private Message Payload to support private message
652 keys and to support the new private message flags. Updated
653 the protocol specs. Flags makes it possible to have for example
656 * Added new type SilcPrivateMessagePayload and defined an API
657 for it in the lib/silcclient/silcprivate.[ch].
659 * Tested private message private keys successfully. Tested the
660 private message key set, unset and list commands with the new
663 * Redefined the Channel Message Payload to include the channel
664 message flags (equal with private message flags) to support
665 for example CTCP style messages.
667 * Defined some of the message (for channel and private message)
668 flags. Updated the protocol specs and added the flags to the
669 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
671 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
673 * Added SilcKeyAgreementStatus type to the key agreement routines
674 to indicate the current status and error if one occured.
675 The status types are defined in the lib/silcclient/silcapi.h.
677 * Added new local command KEY that is used to set and unset private
678 keys for channels, set and unset private keys for private messages
679 with remote clients and to send key agreement requests and
680 negotiate the key agreement protocol with remote client. The
681 key agreement is supported only to negotiate private message keys,
682 it currently cannot be used to negotiate private keys for channels,
683 as it is not convenient for that purpose.
685 * Fixed a minor pending callback setting bug in the function
686 silc_client_get_client_by_id_resolve, now the function works.
687 Affected file lib/silcclient/idlist.c.
689 * Added function silc_net_get_local_port to get local bound
690 port by socket. Added to lib/silcutil/silcnet.[ch].
692 * Added `sockets' and `sockets_count' fields to the SilcClient
693 object. They hold the sockets of the listenning sockets in
694 the client. Listenning sockets may be for example the key
695 agreement server. Affected file lib/silcclient/client.[ch].
696 Added functions the silc_client_add_socket and the
697 silc_client_del_socket. They are exported to the application
700 * Added ~./silc/clientkeys to support other client's public keys.
702 * Renamed verify_server_key client operation to verify_public_key
703 and added one argument to indicate the type of the connection
704 (server, client etc.).
706 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
708 * Added silc_server_connection_auth_request to handle the
709 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
710 silcd/packet_receive.[ch].
712 * Added silc_server_send_connection_auth_request into the
713 silcd/packet_send.c to send the connection auth request packet.
715 * Cleaned up the silcd/protocol.c a bit and fixed some memory
718 * Fixed the public key authentication in responder side in the
719 server. The `auth_data' pointer includes the SilcPublicKey
720 not the path to the public key. Affected file silcd/protocol.c.
722 * Implemented the public key authentication in the initiator side
723 in the server. Affected file silcd/protocol.c.
725 * Removed the [RedirectClient] config section from the server
726 configuration. Is not needed and I don't want to implement it.
728 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Cleaned up the CMODE command in the server. It now works
731 correctly and supports all the modes defined in the protocol.
732 Affected file is silcd/command.c.
734 * Added `hmac_name' field to the SilcChannelEntry in the server
735 to hold the default HMAC of the channel. It can be set when
736 creating the channel (with JOIN command). Affected files
739 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
740 type to indicate the change of the current cipher and hmac
741 on the channel. Client can safely ignore the <cipher> argument
742 (if it chooses to do so) since the CHANNEL_KEY packet will
743 force the channel key change anyway. The <hmac> argument is
744 important since the client is responsible of setting the new
745 HMAC and the hmac key into use.
747 * Fixed the CMODE command in the client library as well.
749 * Tested CMODE command in router environment successfully.
751 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
753 * Show the version of the remote client (or server) when connecting
754 to the server. It is logged to the log file. Affected file
757 * Fixed the KILLED notify handling in the client library. The
758 client must be removed from all channels when receiving the
761 Also, do not remove the client entry when giving the KILL
762 command but when the KILLED notify is received.
764 * Removed silc_idlist_find_client_by_nickname from the server.
765 Not needed anymore. Affected files silcd/idlist.[ch].
767 * Implemented the CHANNEL_CHANGE notify type handling to the
768 server. Affected file silcd/server.c.
772 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

786 * Added function silc_server_get_client_resolve to find the
787 client entry by ID from all ID lists and then resolve it
788 (using WHOIS) if it cannot be found. Affected file is
791 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
793 * Implemented the BAN command to the client library.
795 * The JOIN command in the server now checks the invite list
798 * Changed the silc_command_reply_payload_encode_va and the
799 silc_command_payload_encode_va to support that if argument is
800 NULL it ignores and checks the next argument. Affected file
801 lib/silccore/silccommand.c.
803 * Added silc_server_send_notify_ban to send the BAN notify
804 type between routers.
806 * Chaned the silc_notify_payload_encode to support that if
807 argument is NULL it ignores and checks the next argument.
808 Affected file lib/silccore/silcnotify.c.
810 * Tested ban lists in router environment successfully.
812 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
814 * Implemented BAN command to the server, in silcd/command.[ch].
816 * Removed the BAN and INVITE_LIST modes from the CMODE command
819 * Added function silc_string_match to regex match two strings.
820 Affected files lib/silcutil/silcutil.[ch].

824 * Redefined parts of the SilcChannelEntry in the server to support
825 the new ban and invite lists.
827 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * Redefined the INVITE command. The same command can be used to
830 invite individuals to the channel but also to manage the invite
831 list of the channel (to add to and remove from the invite list).
832 Updated the protocol specs.
834 * Added new command SILC_COMMAND_BAN that can be used to manage
835 the ban list of the channel. Updated the protocol specs.
837 * Removed the channel modes: the SILC_CMODE_BAN and the
838 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
839 in the CMODE command. The equivalent features are now available
840 using INVITE and BAN commands. Updated the protocol specs.
842 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
843 in the network about change in the current ban list. The notify
844 type is not used by the client.
846 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
847 support the invite lists.
849 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
851 * Added new function silc_string_regexify that converts string
852 including wildcard characters into regex string that can
853 be used by the GNU regex library. Added into the file
854 lib/silcutil/silcutil.[ch].
856 Added silc_string_regex_combine to combine to regex strings
857 into one so that they can be used as one regex string by
858 the GNU regex library. Added into the file
859 lib/silcutil/silcutil.[ch].
861 Added silc_string_regex_match to match two strings. It returns
862 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
864 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
866 * Imported GNU regex to the soruce tree into lib/contrib.
867 Fixed some compiler warning from the regex.c.
869 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
871 * Fixed MOTD command in the server to work in router environment.
873 * Fixed the MOTD command in the client library to support
874 the server argument in the command.
876 * Added `nickname_len' argument to the silc_idlist_add_client
877 in the server, as the `nickname' argument may be binary data
880 * Added silc_idlist_get_channels to return all channels from
883 * Implemented LIST command to the server. Affected file is
886 * Implemented the LIST command to the client library and on the
889 * Added [<user count>] argument to the LIST command reply.
890 With private channels the user count is not shown.
892 * Updated TODO and README.
894 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * The client entry's data.registered must be TRUE even with
897 global client entry on global client list. The data.registered
898 is used to check whether the client is anymore in the network,
899 for example with WHOWAS command so it must be valid.
901 * Fixed the WHOWAS command in the server. It now actually works
902 in router environment. Added function into silcd/command_reply.c
903 silc_server_command_reply_whowas_save.
905 * Added silc_idlist_purge function to the silcd/idlist.c
906 to periodically purge the ID Cache.
908 * Fixed INFO command in the server. It works now in router
909 environment. Added <server name> argument to the INFO command
910 reply. Updated the protocol specs.
912 * Fixed minor bug in silc_idcache_purge to not purge if the
913 expire value is zero.
915 * Fixed various bugs in WHOIS and IDENTIFY command handling as
916 they were buggy because of the WHOWAS information.
918 * Fixed local command MSG to handle the async resolving of
919 the remote client properly. It used to fail the first MSG.
920 Affected file silc/local_command.c.
922 * Added `data_len' field to SilcIDCache context.
924 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Update TODO. Todo in commands in the server.
928 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
930 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
931 used by routers as broadcast packet to inform other routers
932 about the changed user mode.
934 Implemented the notify handling in the server. Affected file is
935 silcd/packet_receive.c. Added the function
936 silc_server_send_notify_umode to the silcd/packet_send.[ch].
938 * Added new generic Channel Payload and deprecated the New Channel
939 Payload. The New Channel Payload is now the generic Channel
942 * Added new argument `mode' to the silc_server_send_new_channel
943 as it is required in the Channel Payload now.
945 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
946 and created a new and real SilChannelPayload to represent the
947 new generic Channel Payload. Implemented the encode/decode
948 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
950 * Added silc_server_get_client_channel_list to return the list
951 of channels the client has joined for WHOIS command reply.
952 Affected file silcd/server.[ch].
954 * Implemented the channel list sending in the WHOIS command reply
955 in server and in the client.
957 Implemented the channel list displaying on the user interface
958 as well. Affected file silc/client_ops.c.
960 * Added silc_channel_payload_parse_list to parse list of Channel
961 Payloads. It returns SilcDList list of SilcChannelPayloads.
962 Client for example can use this function to parse the list of
963 channels it receives in the WHOIS command reply. The caller
964 must free the list by calling silc_channel_payload_list_free.
965 Affected files lib/silccore/silcchannel.[ch].
967 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
969 * Added one new argument <user mode> to the WHOIS command reply
970 to return the mode of the user in SILC. Updated the protocol
973 Implemented it to the server and client.
975 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
977 * Fixed the mode printing on the user interface on joining.
978 Affected file silc/client_ops.c.
980 * Implemented the UMODE command and user modes in general to the
981 client library and to the user interface.
983 * Implemented the UMODE command to the server.
985 * The server now sends UNKNOWN_COMMAND error status if client sends
986 unknown command. Affected file silcd/command.c.
988 * All server commands now handle the command identifier the right
989 way when sending the command reply to the client. The client can
990 use to identify the command replies with the identifier.
992 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * Added silc_server_get_client_route to resolve the route to
995 the client indicated by the client ID. Affected file is
998 * Added silc_server_relay_packet as general function to relay
999 packet to arbitrary destination. This deprecates functions
1000 like _send_private_message_key, _relay_notify etc. Affected
1001 file is silcd/packet_send.[ch].
1003 Removed silc_server_send_key_agreement,
1004 silc_server_send_private_message_key and
1005 silc_server_packet_relay_notify functions from the file
1006 silcd/packet_send.[ch].
1010 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1011 server. Affected file silcd/packet_receive.[ch].
1013 * Implemented the KILL command to the client. Implemented the
1014 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1015 Affected files lib/silcclient/command[_reply].c and
1016 lib/silcclient/client_notify.c. Implemented the KILL notify
1017 printing in the user inteface.
1019 * Fixed a lot silc_parse_nick memory leaks from the client
1020 library in the file lib/silcclient/command.c.
1022 * Changed the silc_server_send_notify_on_channels's `sender'
1023 argument from SilcSocketConnection to SilcClientEntry to
1024 check the sender as entry and not as connection object and not
1025 to send to the client provided as argument. The affected file
1026 is silcd/packet_send.[ch].
1028 * The notify packets that are destined directly to the client used
1029 to not to be processed by the server. Now changed that and the
1030 server processes all notify packets. After relaying the packet
1031 to the client the notify packet is processed in the server.
1033 * The silc_server_free_client_data now checks whether there is
1034 pending outgoing traffic for the client and purges the data to
1035 the network before removing the client entry.
1037 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1039 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1040 an client is killed from the SILC Network. Updated the protocol
1043 Added new function silc_server_send_notify_killed to the
1044 silcd/packet_send.[ch].
1046 * Added function silc_server_packet_relay_notify to relay notify
1047 packets that are destined directly to a client. In this case
1048 the server does not process the notify packets but merely relays
1049 it to the client. Affected file silcd/packet_send.[ch].
1051 Added also silc_server_packet_process_relay_notify to check
1052 whereto relay the notify. Affected file is
1053 silcd/packet_receive.[ch].
1055 * Implemented the KILL command to the server.
1059 * Added the backup schema desgined last fall to the protocol
1060 specs for everyone to see. The specification is in the
1061 *-spec-xx.txt draft and the packet type definitions for the
1062 backup routers is in *-pp-xx.txt draft. Thusly, added also
1063 new packet type SILC_PACKET_CELL_ROUTERS.
1065 * A big security problem in the implementation discovered. The
1066 signoff of an client did not cause new channel key generation
1067 which it of course should've done. The channel keys must be
1068 always re-generated when client leaves (or signoffs) the channel.
1069 The silc_server_remove_from_channels funtion now handles
1070 the channel key re-generation.
1072 * Added `sender' argument to the silc_server_send_notify_on_channels
1073 to not to send the client provided as argument. Affected file
1074 silcd/packet_send.[ch].
1076 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1078 * Implemented OPER and SILCOPER commands into the server and
1081 * Added silc_auth_verify and silc_auth_verify_data to verify
1082 the authentication directly from the authentication payload.
1083 It supports verifying both passphrase and public key based
1084 authentication. Affected file lib/silccore/silcauth.[ch].
1086 * Added `hash' field to the SilcIDListData structure. It is the
1087 hash negotiated in the SKE protocol. Affected file is
1090 * Slight redesigning of the SilcAuthPayload handling routines.
1091 Do not send SilcPKCS but SilcPublicKey as argument.
1093 * Implemented the public key authentication support to the
1094 serverconfig. The public key is loaded from the provided path
1095 and saved as authentication data to void * pointer. Thus,
1096 changed the unsigned char *auth_data to void *auth_data;
1098 * Fixed SHUTDOWN command to send the reply before the server
1099 is shutdown. :) Affected file silcd/command.c.
1101 * Fixed fatal bug in CONNECT command. The hostname was invalid
1102 memory and server crashed. Affected file silcd/command.c.
1104 * Fixed fatal bug in CLOSE command. The server_entry became
1105 invalid but was referenced later in the command. Affected file
1108 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1110 * Fixed fatal bug in failure packet handling. Server ignored
1111 the failure and thus crashed when it came.
1115 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1118 that the command may be executed only once in (about) 2 seconds.
1119 The old SILC_CF_LAG flag is same but allows command bursts up
1120 to five before limiting.
1122 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1123 server code. Various commands now includes the CF_LAG_STRICT
1124 flag to disallow any kind of miss-use of the command.
1126 * Fixed the silc_buffer_unformat to not to allocate any data
1127 if the length of the data is zero. It used to allocate the
1128 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1130 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1132 * Changed the format of AdminConnection configuration section
1133 in the server. Added username of the admin to the format.
1134 Affected files silcd/serverconfig.[ch].
1136 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1137 to return admin configuration data by host, username and/or
1140 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1142 * Implemented WHOWAS command to the server. Added the functions:
1144 silc_server_command_whowas_parse,
1145 silc_server_command_whowas_send_reply,
1146 silc_server_command_whowas_from_client and
1147 silc_server_command_whowas_from_server
1149 * Added <Client ID> argument to the WHOWAS command reply. Updated
1150 the protocol specs accordingly.
1152 * Implemented WHOWAS command and command_reply to the client
1155 Implemented the WHOWAS printing on the user interface.
1157 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1159 * Added new argument to the WHOWAS command reply, the real name.
1160 It is an optional argument. Updated the protocol specs.
1162 * Added SilcIDCacheDestructor callback that is registered when
1163 the SilcIDCache is allocated. The callback is called when
1164 an cache entry in the ID Cache expires, or is purged from the
1165 cache. Added into lib/silccore/idcache.[ch].
1167 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1168 to destruct the client entries when the cache entry expires.
1169 Other ID Cache's in server and in the client library ignores
1172 * If the ID Cache entry's `expire' field is zero then the entry
1173 never expires. Added boolean `expire' argument to the
1174 silc_idcache_add function in the lib/silccore/idcache.[ch].
1175 If it is TRUE the default expiry value is used.
1177 * Added silc_server_free_client_data_timeout that is registered
1178 when client disconnects. By default for 5 minutes we preserve
1179 the client entry for history - for WHOWAS command.
1181 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1183 * Added support to the server to enforce that commands are not
1184 executed more than once in 2 seconds. If server receives
1185 commands from client more frequently, timeout is registered
1186 to process the commands. Affected file silcd/command.c.
1187 Added new function silc_server_command_process_timeout.
1189 * Changed NICK_NOTIFY handling in client library to check that
1190 if the client's nickname was changed, so there is no need to
1191 resolve anything from the server.
1193 * Removed error printing from the WHOIS and IDENTIFY commands.
1194 If error occurs then it is ignored silently in the client library.
1195 The application, however, may map the received error to
1196 human readable error string. The application currently maps
1197 the NO_SUCH_NICKNAME error to string.
1199 * Made the command status message public to the application. Moved
1200 them from lib/silcclient/command_reply.c to
1201 lib/silcclient/command_reply.h. The application can map the
1202 received command status to the string with the
1203 silc_client_command_status_message function.
1205 * Added check to the server to check that client's ID is same
1206 as the Source ID in the packet the client sent. They must
1209 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1211 * Added dist-bzip hook to the Makefile.am to make bzip2
1212 compressed distributions.
1214 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1216 * Server now enforces the maximum length for the nickname and
1217 the channel as protocol specification dictates. 128 bytes for
1218 nickname and 256 bytes for channel name.
1220 * Moved the WHOIS printing to the application. The client libary
1221 does not print out the WHOIS information anymore, the application
1222 must do it. Renamed silc_client_command_reply_whois_print to
1223 the silc_client_command_reply_whois_save.
1225 The client's idle time is also sent to the application now, and
1226 the idle is shown on screen.
1228 * Added silc_client_command_reply_identify_save to save the
1229 received IDENTIFY entries.
1231 * Do not check for channel private keys in message sending and
1232 reception if the channel does not have the PRIVKEY mode set.
1233 Affected file lib/silclient/client_channel.c.
1235 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1237 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1238 just surfaced after chaning the JOIN procedure.
1240 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1242 * Added silc_client_get_clients_by_list to get client entries
1243 from Client ID list, that is returned for example by JOIN
1244 and USERS command replies. The application should use this
1245 function for example when JOIN command reply is received to
1246 resolve the clients already on the channel (library does not
1247 do that anymore as USERS command reply is not used in the JOIN
1248 procedure anymore). Affected files lib/silcclient/silcapi.h and
1249 lib/silcclient/idlist.c.
1251 * JOIN command reply and USERS command reply returns now SilcBuffer
1252 pointers instead of unsigned char pointers when returning
1253 the client list and mode list.
1255 * Added <Client ID> argument to the JOIN command reply, mainly
1256 for the server to identify for which client the command was
1257 originally sent. Updated protocol specs accordingly.
1259 * Added SilcDlist private_key pointer to the SilcChannelEntry
1260 in the client to support the channel private keys. Affected
1261 file is lib/silcclient/idlist.h.
1263 * Added SilcChannelPrivateKey argument to the function
1264 silc_client_send_channel_message so that application can choose
1265 to use specific private ke if it wants to. If it is not provided,
1266 the normal channel key is used, unless private keys are set.
1267 In this case the first (key that was added first) is used
1268 as the encryption key.
1270 * Implemented the support for channel private key handling.
1271 Implemented the following functions:
1273 silc_client_add_channel_private_key,
1274 silc_client_del_channel_private_keys,
1275 silc_client_del_channel_private_key,
1276 silc_client_list_channel_private_keys and
1277 silc_client_free_channel_private_keys
1279 Affected file lib/silcclient/client_channel.c.
1281 * Added the support for the private keys in the channel message
1282 sending and encryption and in the message reception and
1283 decryption. Affected funtions are
1284 silc_client_send_channel_message and silc_client_channel_message.
1286 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1288 * Added SKE's key verify callback to the client library's
1289 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1291 * Removed the statement that server (or router) must send USERS
1292 command reply when joining to the channel so that the client
1293 knows who are on the channel. Instead, the client list and
1294 client's mode list is now sent in the JOIN command reply to the
1295 client who joined channel. This is better solution.
1297 * Added function silc_server_get_users_on_channel and function
1298 silc_server_save_users_on_channel to the silcd/server.[ch].
1300 * Removed function silc_server_command_send_users from the
1303 * Do not show topic on the client library anymore. The topic is
1304 sent in the command reply notify to the application and the
1305 application must show the topic now.
1307 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1309 * Added client searching by nickname hash into the IDENTIFY and
1310 WHOIS commands in the server as they were clearly missing from
1311 them. Affected file is silcd/command.c.
1313 * Fixed a bug in private message receiving in the client library.
1314 The remote ID was freed and it wasn't supposed, now it is
1317 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1319 * Minor fix to the channel payload; allocate the data area, as it
1320 needs to be of specific length.
1322 * If the key agreement port is zero then the operating
1323 system will define the bound port. Affected files are
1324 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1326 * Added new function silc_channel_payload_decrypt into the file
1327 lib/silccore/silcchannel.[ch].
1329 * Moved the channel message etc, check from silc_packet_decrypt
1330 to applications. The library calls now a generic
1331 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1332 when the packet is either normal or special. This was done to
1333 allow more wide range of checking that was not allowed when
1334 the code was in library. Now applications can do virtually any
1335 checks to the packet and return to the library the decision how
1336 the packet should be processed. Affected files are
1337 lib/silccore/silcpacket.[ch].
1339 Added silc_server_packet_decrypt_check to the server and
1340 silc_client_packet_decrypt_check to the client library.
1342 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1343 to send with specified source and destination information.
1345 * Channel message delivery between routers was broken after the
1346 channel key distribution was fixed earlier. The channel key
1347 was used be to distributed to other routers as well which is not
1348 allowed by the protocol. Now this is fixed and channel keys
1349 really are cell specific and the channel message delivery between
1350 routers comply with the protocol specification.
1352 * Fixed various commands in server to check also the global list
1353 for the channel entry and not just the local list. The affected
1354 file silcd/command.c.
1356 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1358 * Added assert()s to buffer formatting and unformatting routines
1359 to assert (if --enable-debug) when error occurs. Affected
1360 file: lib/silcutil/silcbuffmt.c.
1362 * Changed to auto-reconnect to check whether the remote host is
1363 router and register the re-connect timeout if it is. It used
1364 to check that whether we are normal server, but router must do
1365 auto-reconnect with another router as well. Affected file
1368 * Removed the [<key len>] option from CMODE command as the cipher
1369 name decides the key length, nowadays. See the defined ciphers
1370 from the protocol specification.
1372 * Added [<hmac>] option to the CMODE command to define the HMAC
1373 for the channel. Added SILC_CMODE_HMAC channel mode.
1375 * Added [<hmac>] option for the JOIN command so that user can
1376 select which HMAC is used to compute the MACs of the channel
1379 * Added Hmac field to the Channel Message Payload. The integrity
1380 of plaintext channel messages are now protected by computing
1381 MAC of the message and attaching the MAC to the payload. The
1382 MAC is encrypted. Now, it is clear that this causes some
1383 overhead to the size of the packet but rationale for this is that
1384 now the receiver can verify whether the channel message decrypted
1385 correctly and also when private keys are set for the channel the
1386 receiver can decrypt the packet with several keys and check from
1387 the MAC which key decrypted the message correctly.
1389 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1390 lib/silccrypt/silccipher.[ch].
1392 * Added silc_hash_len to return the digest length into the
1393 lib/silcrypt/silchash.[ch].
1395 * Rewrote parts of Silc Channel Payload interface in the
1396 lib/silccore/silcchannel.[ch]. The encode function now also
1397 encrypts the packet and parse function decrypts it.
1399 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1401 * Fixed a minor formatting bug in the SKE's key material processing.
1402 It actually might have processed the keys wrong way resulting
1405 * Redefined the mandatory HMAC algorithms and added new algorithms.
1406 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1407 and hmac-md5 truncated to 96 bits. The mandatory is now
1408 hmac-sha1-96. Rest are optional (including the one that used
1409 to be mandatory). Rationale for this is that the truncated HMAC
1410 length is sufficient from security point of view and can actually
1411 make the attack against the HMAC harder. Also, the truncated
1412 HMAC causes less overhead to the packets. See the RFC2104 for
1415 * Added new [hmac] configuration section. The SKE used to use
1416 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1417 is of course wrong. The official names that must be proposed in
1418 the SKE are the ones defined in the protocol specification
1419 (hmac-sha1-96 for example). The user can configure any hmac
1420 using any hash function configured in the [hash] section. At
1421 least, the mandatory must be configured.
1423 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1425 * Added HMAC list to the SKE proposal list. It has now both
1426 hash algorithm list and HMAC list. This makes the protocol
1427 incompatible with previous versions. The SKE now seems to work
1428 the way it is supposed to work, for the first time actually.
1430 * Defined plain Hash algorithms to the protocol specification.
1433 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1435 * Implemented support for key agreement packets into the server.
1436 Added functions silc_server_key_agreement and
1437 silc_server_send_key_agreement. Other than these functions,
1438 server has nothing to do with this packet.
1440 * Added support for private message key packets into the server.
1441 Added functions silc_server_private_message_key and
1442 silc_server_send_private_message_key.
1446 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1447 called in the protocol's final callback instead in the END
1448 protocol state. This makes a little more sense and in the same
1449 time in client we can use the same protocol routines for normal
1450 key exchange and to key agreement packet handling as well.
1452 * Added to both client's and server's KE protocol context the
1453 SilcSKEKeyMaterial pointer to save the key material. We will
1454 bring the key material to the protocol's final callback by doing
1455 this. The final callback must free the key material.
1457 * Added SKE's packet_send callback into client's KE protocol
1458 context so that the caller can choose what packet sending function
1459 is used. This way we can use different packet sending when
1460 doing normal SKE when doing key agreement packet handling (in
1461 the key agreement packet handling we do not want to encrypt
1464 * Implemented the responder side of the key agreement routines
1465 in the client. The client can now bind to specified port and
1466 accept incoming key negotiation. The key material is passed
1467 to the application after the protocol is over.
1469 * Implemented the processing of incoming Key Agreement packet
1470 in the client. Added function silc_client_key_agreement to
1473 * Implemented the intiator side of the key agreement routines
1474 in the client. The client can now initiate key agreement with
1475 another remote client. The key material is passed to the
1476 application after the protocol is over.
1478 * Created client_keyagr.c to include all the key agreement
1481 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1482 SILC_TASK_CALLBACK except that it is not static.
1484 * Created client_notify.c and moved the Notify packet handling
1485 from the client.[ch] into that file.
1487 * Created client_prvmsg.c and moved all private message and
1488 private message key routines from the client.[ch] into that file.
1490 * Create client_channel.c and moved all channel message and
1491 channel private key routines from the client.[ch] into that file.
1493 * Changed silc_client_get_client_by_id_resolve to resolve with
1494 WHOIS command instead of IDENTIFY command, in the file
1495 lib/silclient/idlist.c.
1497 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1499 * Implemented the SKE's responder side to the Client library.
1501 * When FAILURE is received to the protocol do not trust it
1502 blindly. Register a timeout to wait whether the remote closes
1503 the connection as it should do it, only after that process the
1504 actual failure. This was changed to both client and server.
1506 * Added client_internal.h to include some of the structures
1507 there instead of client.h in lib/silcclient/.
1509 * Added function silc_task_unregister_by_callback to unregister
1510 timeouts by the callback function.
1512 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1514 * Some "Incomplete WHOIS info" errors has been appearing on the
1515 log files. Took away the entry->userinfo check from WHOIS
1516 reply sending. The entry->userinfo is now " " if client did not
1517 provide one. I thought this was fixed earlier but something
1518 is wrong still. Let's see if the error still appears.
1520 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1522 * Fixed a minor bug in the login when the channel key is
1523 re-generated in the server. It used to generate the key in
1524 wrong order and thus caused problems in the channel traffic.
1526 * Fixed a minor bug in channel key distsribution after
1527 KICK command. The key was not sent to the router even though
1530 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1532 * Added silc_ske_process_key_material_data as generic routine
1533 to process any key material as the SILC protocol dictates. The
1534 function is used by the actual SKE library but can be used by
1535 applications as well. This relates to the private message keys
1536 and the channel private keys since they must be processed the
1537 same way the normal SILC session keys. The protocol dictates
1538 this. Affected files: lib/silcske/silcske.[ch].
1540 Added also silc_ske_free_key_material to free the
1541 SilcSKEKeyMaterial structure.
1543 * Defined silc_cipher_set_key function to set the key for
1544 cipher without using the object's method function. The affected
1545 files: lib/silccrypt/silccipher.[ch].
1547 * Implemented silc silc_client_add_private_message_key,
1548 silc_client_add_private_message_key_ske,
1549 silc_client_del_private_message_key,
1550 silc_client_list_private_message_keys and
1551 silc_client_free_private_message_keys functions in the
1554 Added functions silc_client_send_private_message_key to send
1555 the Private Message Key payload and silc_client_private_message_key
1556 to handle incoming Private Message Key payload.
1558 * Added Cipher field to the Private Message Key payload to set
1559 the cipher to be used. If ignored, the default cipher defined
1560 in the SILC protocol (aes-256-cbc) is used.
1562 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1564 * Removed lib/silcclient/ops.h file.
1566 Redefined parts of the SILC Client Library API. Created new
1567 file silcapi.h that deprecates the ops.h file and defines the
1568 published Client Library API. Defined also private message key
1569 API and channel private key API into the file.
1571 This is the file that the application must include from the
1572 SILC Client Library. Other files need not be included by
1573 the application anymore.
1575 * Added new key_agreement client operation callback and also
1576 defined the Key Agreement library API for the application.
1578 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1580 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1581 is used by clients to request key negotiation between another
1582 client in the SILC network. If the negotiation is started it
1583 is performed using the SKE protocol. The result of the
1584 negotiation, the secret key material, can be used for example
1585 as private message key.
1587 Implemented the Key Agreement payload into the files
1588 lib/silccore/silauth.[ch].
1590 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1592 * Redefined ciphers for the SILC protocol. Added some new ciphers
1593 and defined the key lengths for the algorithms. Changed the
1594 code accordingly. The default key length is now 256 bits.
1596 * Fixed SKE key distribution function silc_ske_process_key_material
1597 when the key length is more than 128 bits. The default key
1598 length in SILC is now 256 bits.
1600 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1601 to indicate unsupported algorithm.
1603 * Renamed rijndael.c to aes.c and all functions as well.
1605 * Fixed a long standing channel key setting bug in client library.
1606 Weird that it has never surfaced before.
1608 * Fixed bug in channel deletion. If the entire channel is removed
1609 then it must also delete the references of the channel entry
1610 from the client's channel list as the client's channel entry and
1611 the channel's client entry share same memory.
1613 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1615 * Implemented CONNECT and SHUTDOWN commands in the client.
1617 * Implemented CLOSE command to the client.
1619 * Added the function silc_idlist_find_server_by_name into the
1620 files silcd/idlist.[ch].
1622 Added the function silc_idlist_find_server_by_conn into the
1623 files silcd/idlist.[ch].
1625 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1627 * DIE command was renamed to SHUTDOWN. Updated the both code
1630 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1631 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1633 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1636 * Added function silc_server_create_connection function to create
1637 connection to remote router. My server implementation actually
1638 does not allow router to connect to normal server (it expects
1639 that normal server always initiates the connection to the router)
1640 so the CONNECT command is only good for connecting to another
1643 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1646 or some other client was kicked from the channel.
1648 Implemented the handling of the notify type to both client
1651 Implemented silc_server_send_notify_kicked to send the KICKED
1652 notify. It is used to send it to the server's primary router.
1654 * Implemented the KICK command into server and client.
1656 * Added `query' argument to the silc_idlist_get_client function
1657 to indicate whether to query the client from server or not if
1660 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1661 to indicate that the client is not channel founder.
1665 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1667 * Removed the rng context from SilcPacketContext structure and
1668 changed that the packet routine uses the Global RNG API.
1670 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1672 * Added support for quit message that client can "leave" on the
1673 channel when it quits the SILC. It is ditributed inside the
1674 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1676 Added silc_server_free_client_data that will take the
1677 signoff message as argument.
1679 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1681 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1683 * Updated parts of the protocol specification to keep it up
1686 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1688 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1689 payloads in one packet.
1691 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1692 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1693 use now the new List flag.
1695 * Also deprecated the following packet types: REPLACE_ID,
1696 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1698 * Added list support for Notify packet in server.
1700 * Added silc_server_send_notify_channel_change to send the
1701 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1702 the silc_server_send_replace_id.
1704 * Added silc_server_send_notify_nick_change to send the
1705 NICK_CHANGE notify type. Deprecates the function
1706 silc_server_send_replace_id.
1708 * Added silc_server_send_notify_join to send the JOIN notify type.
1709 Deprecates the function silc_server_send_new_channel_user.
1711 * Added silc_server_send_notify_leave to send LEAVE notify type.
1712 Deprecates the function silc_server_send_remove_channel_user.
1714 * Added silc_server_send_notify_cmode and
1715 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1716 types. Deprecates the silc_server_send_set_mode function.
1718 * Added SERVER_SIGNOFF notify type to indicate that server has
1719 quit. This means that all clients on the channel from that
1720 server will drop. This can be also used when netsplit happens.
1722 Deprecated REMOVE_ID packet type since it is not needed anymore
1725 Added silc_server_send_notify_server_signoff to send the
1726 SERVER_SIGNOFF notify type. Deprecates the function
1727 silc_server_send_remove_id.
1729 Added also silc_server_send_notify_signoff to send the
1730 SIGNOFF notify type.
1732 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1733 SILC protocol from this day on. Changed the protocol
1734 specification as well.
1736 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1737 notify type. It is used between routers to notify about
1738 topic changes on a channel.
1740 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1743 * Partly updated the protocol specification to comply with the
1744 changes now made. It is still though a bit outdated.
1746 * The JOIN notify type now takes one extra argument <Channel ID>.
1747 The packet used to be destined to the channel but now the
1748 JOIN type may be sent as list thus it is impossible to
1749 destine it to any specific channel. By adding this argument
1750 it is again possible.
1752 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1754 * Added CREDITS file. The CHANGES and CREDITS file will appear
1755 in the distribution as well.
1757 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1759 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1760 types in the server's silcd/packet_receive.c.
1762 * Implemented CMODE and CUMODE to work in router environment.
1764 * Fixed minor encoding and decoding buglet from the
1765 lib/silccore/silcmode.c.
1767 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1770 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1772 * Changed all SilcConfigServer* and silc_config_server* to
1773 SilcServerConfig* and silc_server_config*, respectively.
1776 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1778 * Associated the ID (client or server ID) to the Authentication
1779 Payload to avoid any possibility of forging. Updated the
1780 protocol specification and the code accordingly.
1782 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1784 * The RSA key length is now save to the RsaKey context in the
1785 key generation process in lib/silccrypt/rsa.c. The key length
1786 is now used to figure out the maximum size of the block allowed
1787 to be encrypted/signed.
1789 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1790 is equivalent to the silc_mp_mp2bin but does not allocate any
1793 * Changed silc_mp_mp2bin API to take length argument. If it is
1794 non-zero then the buffer is allocated that large. If zero, then
1795 the size is approximated using silc_mp_sizeinbase, which however
1798 * Created Global RNG API which is global RNG that application can
1799 initialize. After initializing, any routine anywhere in the
1800 code (including library) can use RNG without allocating a new
1801 RNG object. This was done to allow this sort of use of the
1802 RNG in code that has no chance to allocate RNG object. All
1803 applications currently allocate this and many routines in the
1804 library use this. Affected file lib/silccrypt/silcrng.[ch].
1806 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1807 it to use the Global RNG API.
1809 * Defined Authentication Payload into protocol specification that
1810 is used during SILC session to authenticate entities. It is
1811 used for example by client to authenticate itself to the server
1812 to obtain server operator privileges.
1814 Implemented this payload into the lib/silccore/silcauth.[ch].
1815 Implemented also routines for public key based authentication
1816 as the new protocol specification dictates.
1818 Moved definitions of different authentication methods from
1819 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1821 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1822 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1823 silc_pkcs_verify_with_hash functions into the file
1824 lib/silccrypt/silcpkcs.[ch].
1826 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1828 * The client entry's userinfo pointer must be always valid.
1829 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1830 will fail since it requires the userinfo. Now, the userinfo
1831 is allocated as "" if actual userinfo does not exist. Actually,
1832 it must exist and it is totally Ok to drop client connections
1833 that does not announce the userinfo. However, we will make
1834 this workaround for now.
1836 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1837 to return the remote port by socket.
1839 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1841 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1842 SILC_SERVER_PENDING_EXEC and added an new macro
1843 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1844 data or when error occurs while processing the pending command.
1846 Added new argument `destructor' into silc_server_command_pending
1847 and to the SilcServerCommandPending object. This destructor is
1848 now called after calling the pending callback or if error occurs
1849 immediately. If error occurs the actual pending callback won't
1850 be called at all - only the destructor. The destructor may be
1851 NULL if destructor is not needed.
1853 All this applies for client library code as well. Similar
1854 changes were made there as well for the pending commands.
1856 In the client, the application must now allocate the
1857 SilcClientCommandContext with the silc_client_command_alloc
1860 * Added reference counter to the SilcServerCommandContext. Added
1861 function silc_server_command_alloc and silc_server_command_dup
1864 Same type of functions added to the client library for the same
1867 * Removed the cmd_ident from IDListData away since it is now
1868 global for all connections. It is the command identifier used
1869 in command sending and with pending commands. The affected file
1872 * Added reference counter to the SilcSocketConnection objecet to
1873 indicate the usage count of the object. The object won't be
1874 freed untill the reference counter hits zero. Currently only
1875 server uses this, and client ignores it. The client must be
1876 set to use this too later. The affected files are
1877 lib/silccore/silcsockconn.[ch]. Added also the function
1878 silc_socket_dup to increase the reference counter.
1880 This was mainly added because it is possible that the socket
1881 is removed underneath of pending command or other async
1882 operation. Now it won't be free'd and proper DISCONNECTING
1883 flags, etc. can be set to avoid sending data to connection that
1884 is not valid anymore.
1886 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1887 the connection. After that it sets SILC_SET_DISCONNECTED.
1888 It is, however, possible that the socket data is not still freed.
1889 The silc_server_packet_process now checks that data is not
1890 read or written to connection that is DISCONNECTED. The socket
1891 get's freed when the reference counter hits zero.
1893 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1895 * Changed the client operation API: channel_message operation's
1896 `sender' is now the client entry of the sender, not the nickname
1897 and the `channel' is the channel entry, not the channel name.
1899 In the private_message operation the `sender' is now also the
1900 client entry of the sender not the nickname.
1902 Affected file is lib/silcclient/ops.h and all applications
1903 using the client operations.
1905 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1907 * Moved the calling of ops->connect() from connect_to_server_final
1908 into receive_new_id functin since that is the point when the
1909 client is actually allowed to send traffic to network. The
1910 affected file is lib/silcclient/client.c.
1912 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1914 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1915 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1916 (if needs broadcasting) instead of broadcasting the packets one
1917 by one which would make a burst in the network traffic.
1919 * Added `broadcast' argument to the functions in silcd/server.[ch]
1920 silc_server_create_new_channel[_with_id] to indicate whether
1921 to send New Channel packet to primary router.
1923 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1925 * Added new function into the silcd/server.[ch] files:
1926 silc_server_create_new_channel_with_id to create new channel with
1927 already existing Channel ID.
1929 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1930 lib/silccore/silcpacket.h. This packet is used t send list of
1931 Set Mode payloads inside one packet. Server uses this to set
1932 the modes for the channels and clients on those channels, that it
1933 announced to the router when it connected to it. The protocol
1934 specification has been updated accordingly.
1936 * The silc_server_new_channel did not handle the packet coming
1937 from normal server as it normally does not send that. However,
1938 when it announces its channels it does send it. Implemented
1939 the support for that.
1941 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1942 into the file lib/silccore/id.h.
1944 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1946 * Fixed memory leaks in the functions silc_idlist_del_client,
1947 silc_idlist_del_channel and silc_idlist_del_server in the file
1948 silcd/idlist.c. All of those leaked like a sieve.
1950 * Fixed some small memory leaks in the client's function
1951 silc_client_notify_by_server.
1953 * Added functions into silcd/server.c: silc_server_announce_clients,
1954 silc_server_announce_channels and silc_server_announce_server.
1955 These functions are used by normal and router server to announce
1956 to its primary router about clients, channels and servers (when
1957 router) that we own. This is done after we've connected to the
1960 These functions effectively implements the following packet types:
1961 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1962 and SILC_PACKET_NEW_ID_LIST.
1964 * Added new functions into the silcd/packet_receive.[ch]:
1965 silc_server_new_id_list, silc_server_new_channel_list and
1966 silc_server_new_channel_user_list to handle the incoming
1967 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1969 * Added support of changing Channel ID in the function
1970 silc_server_replace_id. If the server that announces a channel
1971 to the router already exists in the router (with same name but
1972 with different Channel ID), router is responsible to send
1973 Replace ID packet to the server and force the server to change
1974 the Channel ID to the one router has.
1976 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1977 client that the Channel ID has been changed by the router. The
1978 normal server sends this to the client. Client must start using
1979 the new Channel ID as the channel's ID.
1981 Implemented handling of this new type into lib/silcclient/client.c
1982 into the function silc_client_notify_by_server.
1984 * Added new function silc_idlist_replace_channel_id into the files
1985 silcd/idlist.[ch] to replace the Channel ID.
1987 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1989 * Call silc_server_command_identify_check always when processing
1990 the IDENTIFY command in silcd/command.c
1992 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1994 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1995 send keepalive packets. The packet can be sent by clients,
1996 servers and routers.
1998 Added function silc_socket_set_heartbeat into the file
1999 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2000 If not set, the heartbeat is not performed. The actual
2001 heartbeat is implemented in the low level socket connection
2002 library. However, application is responsible of actually
2005 Added silc_server_send_heartbeat to send the actual heartbeat
2006 packet into silcd/packet_send.[ch]. Server now performs
2007 keepalive with all connections.
2009 * Added silc_task_get_first function into lib/silcutil/silctask.c
2010 to return the timeout task with shortest timeout. There was a bug
2011 in task unregistration that caused problems. TODO has been
2012 updated to include that task system must be rewritten.
2014 * The client library will now resolve the client information when
2015 receiving JOIN notify from server for client that we know but
2016 have incomplete information.
2018 * Rewrote parts of silc_server_remove_from_channels and
2019 silc_server_remove_from_one_channel as they did not remove the
2020 channel in some circumstances even though they should've.
2022 * Encryption problem encountered in server:
2024 The LEAVE command used to send the Channel Key packet to the
2025 router immediately after generating it. However, the code
2026 had earlier sent Remove Channel user packet but not immediately,
2027 ie. it was put to queue. The order of packets in the router
2028 was that Channel Key packet was first and Remove Channel User
2029 packet was second, even though they were encrypted in the
2030 reverse order. For this reason, MAC check failed. Now, this
2031 is fixed by not sending the Channel Key packet immediately but
2032 putting it to queue. However, this is more fundamental problem:
2033 packets that are in queue should actually not be encrypted
2034 because packets that are sent immediately gets encrypted
2035 actually with wrong IV (and thus MAC check fails). So, packets
2036 that are in queue should be encrypted when they are sent to
2037 the wire and not when they put to the queue.
2039 However, the problem is that the current system has not been
2040 designed to work that way. Instead, the packet is encrypted
2041 as soon as possible and left to the queue. The queue is then
2042 just purged into wire. There won't be any fixes for this
2043 any time soon. So, the current semantic for packet sending
2046 o If you send packet to remote host and do not force the send
2047 (the packet will be in queue) then all subsequent packets to the
2048 same remote host must also be put to the queue. Only after the
2049 queue has been purged is it safe again to force the packet
2052 o If you send all packets immediately then it safe to send
2053 any of subsequent packets through the queue, however, after
2054 the first packet is put to queue then any subsequent packets
2055 must also be put to the queue.
2057 Follow these rules and everything works fine.
2059 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * Added new function silc_server_remove_clients_by_server to
2062 remove all client entries from ID list when the server connection
2063 is lost. In this case it is also important to invalidate all
2064 client entires as they hold the invalid server entry. This
2065 fixes fatal bug when server has lost connection and will reconnect
2068 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2070 * Made some sanity checks to silc_server_daemonise like to check
2071 whether the requested user and group actually exists.
2073 * Added sanity check to SKE's silc_ske_responder_finish to check
2074 that the public and private key actually is valid.
2076 * Invalidate the client's nickname when receiving Replace ID
2077 packet and the Client ID is being replaced. This means that the
2078 server will query the nickname if someone needs it (client)
2081 * Sort the ID Cache in client library when the ID Cache data
2082 has changed (needs sorting).
2084 * Do not allow for SILC client to create several connections to
2085 several servers. The client does not support windows right now
2086 and generating multiple connections causes weird behaviour.
2088 Irssi-silc client does support windows and can handle several
2089 connections without problems, see: www.irssi.org and SILC plugin.
2091 * Fixed some places where client was added to the IDList. The
2092 rule of thumb is following (in order to get everything right):
2093 If the client is directly connected local client then the
2094 `connection' argument must be set and `router' argument must be
2095 NULL to silc_idlist_add_client function. If the client is not
2096 directly connected client then the `router' argument must
2097 bet set and the `connection' argument must be NULL to the
2098 silc_idlist_add_client function.
2100 * The funtion silc_server_packet_send_local_channel actually did
2101 not check whether the client was locally connected or not. It
2102 does that now. Fixed a bug related to LEAVE command.
2104 * Fixed Remove Channel User payload parsing bug in server's
2105 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2107 * The server's silc_server_save_channel_key now checks also the
2108 global ID list for the channel as it might not be in the local
2109 list. Fixed a bug related to LEAVE command.
2111 * Is this the end of the [<unknown>] buglet that has been lurking
2112 around for a long time? A little for loop fix in server's
2113 silc_server_command_whois_parse that is used by both IDENTIFY
2114 and WHOIS command. At least, this was a clear bug and a cause
2115 of one type of [<unknown>] buglet.
2117 * WHOIS and IDENTIFY commands call the function
2118 silc_server_command_[whois/identify]_check function even if
2119 we are not router server.
2121 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2123 * Added --with-gmp configuration option. If set the GMP
2124 is always compiled in the SILC source tree. If not set then
2125 it is checked whether the system has the GMP3 installed. If
2126 it has then the GMP won't be compiled (the system's headers
2127 and library is used), if it doesn't have it then the GMP is
2128 compiled in the SILC source tree.
2130 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2132 * Changed RSA private exponent generation to what PKCS #1
2133 suggests. We try to find the smallest possible d by doing
2134 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2135 not security fix but optimization.
2137 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2139 * Added new config entry [Identity] to fork the server and run
2140 it as specific user and group. A patch from Bostik.
2142 * Imported Dotconf configuration library into lib/dotconf.
2143 This will be used to create the SILC configuration files later.
2144 It will appear in the distsribution after this commit.
2146 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * A big code auditing weekend happening. Auditing code for
2149 obvious mistakes, bugs and errors. Also, removing any code
2152 Removed files for being obsolete:
2154 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2155 inline in the file lib/silcutil/silcbuffer.h)
2157 o lib/silcutil/silcbufutil.c (the header has inline versions)
2159 Changed code to fix possible error conditions:
2161 o The buffer formatting routines now check that the destination
2162 buffer really has enough space to add the data. This applies for
2163 both buffer formatting and unformatting
2164 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2165 unformatting was changed to accomodate following rules:
2166 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2167 sent to the function while XXX_*STRING will not allocate or copy
2168 the data into the buffer. Instead it sets the pointer from the
2169 buffer into the pointer sent as argument (XXX_*STRING used to
2170 require that the pointer must be allocated already). This change
2171 makes this whole thing a bit more consistent and more optimized
2172 (note that the data returned in the unformatting with XXX_*STRING
2173 must not be freed now). The routines return now -1 on error.
2175 o Tried to find all code that use buffer_format and buffer_unformat
2176 and added return value checking to prevent formatting and
2177 especially unformatting errors and possible subsequent fatal
2180 o Changed ske->x and ske->KEY to mallocated pointers in
2181 lib/silcske/silcske.h. Fixed possible data and memory leak.
2183 o Added return value checking to all *_parse* functions. Fixed
2184 many memory leaks as well.
2186 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2187 so that buffer overflows would not happen. All code now also
2188 checks the return value as it can fail.
2190 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2192 * Added reconnection support to server if the normal server looses
2193 its connection to the router (for example if router is rebooted).
2194 The server performs normal reconnection strategy implemented
2195 to the server. Affected file silcd/server.c.
2197 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2199 * Added new packet type SILC_PACKET_SET_MODE that is used to
2200 distribute the information about changed modes (for clients,
2201 channels and clients channel modes) to all routers in the
2202 network. Updated the protocol specification accordingly.
2204 Added functions into silcd/packet_send.c and
2205 silcd/packet_receive.c: silc_server_send_set_mode,
2206 silc_server_set_mode.
2208 Added new files silcmode.[ch] into lib/silccore that implements
2209 the encoding and decoding of Set Mode Payload. Added new type
2210 SilcSetModePayload. Moved the definitions of different modes
2211 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2213 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2215 * Oops, a little mistake in server's connection authentication
2216 protocol. The protocol is not ended with FAILURE but with
2217 SUCCESS if the authentication is Ok. :) Affected file is
2220 * Implemented NICK_CHANGE notify handling in server in the file
2221 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2222 the local clients on the channel. After the changing nickname
2223 in router environment snhould work and the [<unknown>] nickname
2224 should appear no more.
2226 The silc_server_replace_id function that receives the Replace ID
2227 payload now sends the NICK_CHANGE notify type also in the file
2228 silcd/packet_receive.c
2230 * Changed WHOIS and IDENTIFY command to support the maximum amount
2231 of arguments defined in protocol specs (3328 arguments). This
2232 fixed a bug that caused problems when there were more than three
2235 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2237 * Added extra parameter, command identifier, to the
2238 silc_client_send_command so that explicit command identifier
2241 Changed that ID list routines uses specific command identifier
2242 when sending WHOIS/IDENTIFY requests to the server so that they
2243 can be identified when the reply comes back.
2245 Affected files lib/silcclient/command.[ch],
2246 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2248 * Added `sender' argument to silc_server_packet_send_to_channel
2249 to indicaet the sender who originally sent the packet to us
2250 that we are now re-sending. Ignored if NULL. Affected file
2251 silcd/packet_send.[ch].
2253 * Added some server statistics support in silcd/server_internal.h
2254 SilcServerStatistics structure and around the server code. Also
2255 send some nice statistics information when client is connecting
2258 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2260 * Fixed channel ID decoding in server's JOIN command reply in
2261 silcd/command_reply.c
2263 * Fixed braodcasting of replace ID payload to not to send it if
2264 we are standalone server in silcd/packet_receive.c.
2266 * Fixed all channel message sending routines to not to send
2267 packets to clients that has router set, since they are routed
2268 separately in the same function earlier. Affects file
2269 silcd/packet_send.c and all channel packet sending functions.
2271 * In USERS reply, res_argv[i] are not allocated, the table
2272 is allocated. Thus changed that free the table, not its
2275 * In server's whois_check and identify_check if the client is
2276 locally connected do not send any WHOIS commands - they are not
2279 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2281 * Fixed some minor bugs in client when sending WHOIS command. The
2282 arguments was in wrong order.
2284 * Removed statis function add_to_channel from server in
2285 silcd/command.c that was previously used with the joining but
2288 * Tested USERS command in router environment successfully with two
2289 routers, two servers and two clients.
2291 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2293 * Reorganized the USERS command and command reply in client library
2294 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2295 When the command is given by user we register a pending command
2296 callback that will reprocess the command after the reply has been
2297 received from the server. When reprocessing the packet we then
2298 display the information. Thus, the USERS information is displayed
2299 now in the command callback instead of in the command reply
2300 callback. The processing of the command is same as previously
2301 when server has sent the command reply in the JOINing process.
2303 * Added to USERS command in silcd/command_reply.c to join the client,
2304 we didn't use to know about, to the channel after we've created
2305 a client entry for it. Also, for clienet we did know already still
2306 check whether it is on the channel or not and add it if not.
2308 * Removed silc_server_command_join_notify as the function and its
2311 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2313 * Changed the client's pending command handling to the same as the
2314 server's pending command handling. It is also now possible to
2315 execute command reply functions from other command reply
2316 function as the function callbacks for commands and command
2317 replies are one and same. The pending commands are not static
2318 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2319 in client connection context. Thus, pending commands are server
2320 connection specific as it is convenient.
2322 Changed the function silc_client_command_pending and
2323 silc_client_command_pending_del and added new function
2324 silc_client_command_pending_check. Removed the
2325 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2328 * Added cmd_ident, current command identifier, to the client
2329 connection context in lib/silcclient/client.h to keep track on
2330 command identifiers used in command sending. Client's command reply
2331 function handling now supports the mandatory command identifiers.
2333 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2334 funtions in client to fully support pending command callbacks.
2336 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2337 as one of the arguments to the application in the command reply
2340 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2341 before first releasing SILC but came back. Now it is removed again
2342 and should come back nomore. The FORWARDED flag was used only
2343 by the JOINing procedure by forwarding the command packet to router.
2344 Now, the JOINing procedure has been changed to more generic (due
2345 to various router environment issues) and FORWARDED is not needed
2346 anymore for anything. The protocol specification is yet to be
2349 Now, removed silc_server_packet_forward from server and the flag
2350 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2352 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2354 * Renamed NAMES command to USERS command. The NAMES was named that
2355 due to historical reasons. Now it is renamed. Also, rewrote
2356 parts of the USERS command. The nickname list is not sent anymore
2357 by the server. Only Client ID and mode lists are sent in the USERS
2358 command. Changed this also to the protocol specification.
2360 The client now resolves the names and stuff after it receives
2361 the USERS list from the server when joining to the channel.
2363 * WHOIS and IDENTIFY commands has been changed to support multiple
2364 Client ID's per command. One can now search for multiple users
2365 in the network by sending only one WHOIS or IDENTIFY command.
2366 Changed the code and the protocol specifications.
2368 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2369 uses silc_server_command_whois_parse to parse the request. */
2371 * If normal server, do not parse the WHOIS and IDENTIFY requests
2372 before sending it to the router. Saves some time.
2374 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2376 * Fixed JOIN command on client library. Wrong number of arguments
2377 used to crash the client.
2379 * Added silc_server_channel_has_global function to check whether
2380 channel has global users or not.
2382 * Added silc_server_channel_has_local function to check whether channel
2383 has locally connected clients on the channel.
2385 * The silc_server_remove_from_one_channel now checks whether the
2386 channel has global users or not after given client was removed from
2387 the channel. It also checks whether the channel has local clients
2388 on the channel anymore. If it does not have then the channel entry
2389 is removed as it is not needed anymore.
2391 * The silc_server_notify now checks on JOIN notify whether the joining
2392 client is one of locally connected or global. If it is global then
2393 the channel has now global users on the channel and that is marked
2394 to the channel entry. Also, it now saves the global client to
2395 global list who is joining and JOINs it to the channel. This is
2396 for normal server, that is.
2398 Changed silc_server_send_notify_on_channel,
2399 silc_server_packet_relay_to_channel and
2400 silc_server_packet_send_to_channel check if we are normal server
2401 and client has router set (ie. global client) do not send the
2402 message to that client, as it is already routed to our router.
2404 * Implemented LEAVE notify type handling in silc_server_notify
2407 * Tested LEAVE command in router environment successfully. Tested
2408 with two routers, two servers and two clients.
2412 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2414 * Implemented SIGNOFF notify type handling in silc_server_notify
2417 * silc_server_remove_id now removes the client entry from all channels
2418 it has joined and thusly sends SIGNOFF notify type.
2420 * Rewrote the NAMES list generation in server by removing two excess
2421 loops. The lists are created now inside one loop.
2423 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2425 * silc_server_remove_channel_user checks now also global list
2426 for channel and client.
2428 * silc_server_new_channel_user checks now both local and global
2429 list for channel and client. Fixed a bug in client id decoding.
2430 Used to decode wrong buffer.
2432 * silc_server_channel_message checks now both local and global
2433 list for channel entry.
2435 * Tested channel joining (hence JOIN) in router environment
2436 successfully. Tested with two routers, two servers and two
2439 * Tested channel message sending in router environment successfully.
2441 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2443 * Added silc_server_save_channel_key into server.[ch] to save the
2444 received channel key in Channel Key payload processing. It is
2445 also used in JOIN command reply handling.
2447 Equivalent function silc_client_save_channel_key added into
2448 client.[ch] into client library.
2450 * Changed JOIN command reply to send information whether the channel
2451 was created or not (is existing already) and the channel key
2452 payload. Changed protocol specs accordingly.
2454 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2455 the request was sent by ID and not by nickname. Crashed on
2458 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2460 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2461 now correctly save the received data.
2463 * silc_server_free_sock_user_data now notifies routers in the
2464 network about entities leaving the network.
2466 At the same time implemented functions silc_server_remove_id
2467 and silc_server_send_remove_id to receive and send REMOVE_ID
2468 packets. The packet is used to notify routers in the network
2469 about leaving entities. The ID removed will become invalid in
2472 * Added function silc_idlist_del_server into server. Removes and
2473 free's server entry from ID list.
2475 * silc_server_private_message function now checks, if we are router,
2476 that the destination ID really is valid ID, naturally.
2478 * In router when NEW_ID packet is received (for new client) the
2479 hash of the Client ID is saved in the ID Cache but the
2480 client->nickname is set to NULL, instead of putting the hash
2483 IDENTIFY command now also checks that client->nickname must be
2484 valid. If it is not if will request the data from the server who
2485 owns the client. Added new function
2486 silc_server_command_identify_check.
2488 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2489 to set the command to already allocated Command Payload.
2491 * Tested private message sending in router environment with two
2492 routers, two servers and two clients. Fixed minor bugs and now
2495 * Fixed segfault from client's NAMES command. Used to crash if
2498 * Forwarded packets must not be routed even if it is not destined
2499 to the receiver. Changed server code comply with this.
2501 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2503 * Added `require_reverse_mapping' boolean value to ServerParams
2504 structure. If TRUE (not default) the server will require that
2505 the connecting host has fully qualified domain name.
2507 If the reverse mapping is not required and hostname could not be
2508 found the IP address is used as hostname.
2510 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2512 * Implemented version string checking to both client and server.
2513 The check is incomplete currently due to the abnormal version
2514 strings used in development version of SILC.
2516 * Changed all command functions in server to use the new
2519 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2521 * Changed char *data to unsigned char *data in ID Cache system to
2522 support binary data as ID Cache data. Changed code to support
2523 binary data in lib/silccore/idcache.c.
2525 * Renamed silc_server_packet_relay_command_reply to
2526 silc_server_command_reply as it is normal packet receiving
2527 function. Rewrote the function to accept command replys for
2528 servers and not only for clients.
2530 * Mark remote router always as registered server if we are connecting
2531 to it. Otherwise, commands sent by the router to us are ignored.
2533 * All ID List find routines now returns the ID Cache Entry pointer
2534 as well if requested.
2536 * WHOIS command works now in router environment, tested with two
2537 routers, two servers and two clients.
2539 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2540 in router environment (as it is almost equivalent to WHOIS) but
2541 hasn't been tested thoroughly. Added new functions:
2543 silc_server_command_identify_parse
2544 silc_server_command_identify_send_reply
2545 silc_server_command_identify_from_client
2546 silc_server_command_identify_from_server
2548 * Disabled route cache adding because adding two different ID's with
2549 same IP replaces the old cache entry thus giving wrong route.
2550 The entry->router->connection is always the fastest route anyway
2551 so route cache may not be needed. Of course, new routes maybe
2552 established after receiving the ID when the entry->router->connection
2553 might not be anymore the most optimal.
2555 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * Add route cache for received ID for fast routing.
2559 * Added silc_server_packet_route to route received packet on router
2560 that is not destined to us.
2562 * Renamed silc_server_get_route to silc_server_route_get.
2564 * Added id_string and id_string_len fields into SilcServer to
2565 include encoded ServerID for fast comparing without excess
2566 encoding of the ID's.
2568 * Cleaned up WHOIS command on server side. Added following static
2571 silc_server_command_whois_parse
2572 silc_server_command_whois_check
2573 silc_server_command_whois_send_reply
2574 silc_server_command_whois_from_client
2575 silc_server_command_whois_from_server
2577 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2578 arguments in command replies. All command functions should be
2579 updated to use this macro.
2581 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Minor typo fixes on command reply handling on server.
2585 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2587 * Added silc_server_command_add_to_channel internal routine to add
2588 the client to the channel after router has created the channel and
2589 sent command reply to the server.
2591 * Added generic silc_server_send_command to send any command from
2594 * Use static buffer with ID rendering instead of duplicating data.
2596 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2598 * Fixed a channel user mode bug when joining to a channel server gave
2599 everybody channel founder rights, oops.
2601 * We mark ourselves as the router of the incoming server connection
2602 if we are router ourselves. This way we can check in some packet
2603 sending functions whether it is locally connected server. For
2604 incoming router connections we put NULL.
2606 * For router sending packets locally means now always sending the
2607 packet cell wide; to local clients and local servers. For normal
2608 server sending packet locally means sending it to only local
2611 * Fixed the JOIN command to really work in router environment. If the
2612 channel is created it is always created by the router. Router is
2613 also responsible of making the initial joining to the channel,
2614 sending JOIN notify to the sending server and distributing
2615 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2616 does not exist server doesn't do anything else but forward the
2617 command to the router which performs everything.
2619 * Added silc_server_send_channel_key function to send the Channel Key
2622 * Added silc_server_create_channel_key to create new channel key. The
2623 channel key is now re-generated everytime someone joins or leaves
2624 a channel, as protocol dictates. Note: channel->key_len is the
2627 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2630 packet_receive.[ch] to separate packet sending and receiving
2631 routines. The server.[ch] now includes everything else including
2632 actual packet processing (writing and reading data) and other
2635 Renamed silc_server_private_message_send_internal to
2636 silc_server_send_private_message. The routine is still though
2637 used only to relay private messages as server does not send
2638 private messages itself.
2640 Renamed silc_server_new_channel to silc_server_create_new_channel
2641 and added new function sicl_server_new_channel that handles the
2642 incoming New Channel packet. Added also new sending function
2643 silc_server_send_new_channel to send New Channel Payload.
2645 * Added new function silc_server_notify to process incoming notify
2646 packet to the server/router. Server may then relay the notify
2647 to clients if needed.
2649 * Added new function silc_server_new_channel_user to process incoming
2650 New Channel User packet. Router will redistribute the packet and
2651 send JOIN notify to its local clients and locally connected servers
2652 if needed. Normal server will send JOIN notify to its local client
2653 on same channel when received this packet. Added also corresponding
2654 sending function silc_server_send_new_channel_user to sent the
2657 * Added boolean route argument to send_notif_to_channel and
2658 packet_send_to_channel functions to attempt to route the packet
2659 if it is TRUE and send only locally if it is FALSE.
2661 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2663 * silc_server_replace_id now broadcasts the received replace ID
2664 packet if it is not broadcast packet already. The router must
2665 broadcast to inform other routers about changed ID.
2667 * Added backpointer to server's router into SilcServer context in
2668 silcd/server_internal.h.
2670 * Fixed silc_server_packet_broadcast to send correct broadcast
2673 * The channel key is now distributed to the local client as soon
2674 as it is received from the router (in router environment) so that
2675 no other packet may be sent for the channel until client has
2678 * silc_server_remove_channel_user now broadcasts the received
2679 Remove Channel User packet if it is not broadcast packet already.
2680 The router must broadcast to inform other routers about removed
2683 * Added users field into SilcPacketContext that is a reference count
2684 of the context. One can increase the reference count by calling
2685 silc_packet_context_dup which is now changed to just increase the
2686 reference count instead of duplicating the data. The reference
2687 count is decresed by calling silc_packet_context_free that will
2688 free the data after the reference count hits zero.
2690 For now on the packet context and everything allocated into it
2691 (including the raw packet from network) must be freed by calling
2692 the new silc_packet_context_free function. Added also new function
2693 silc_packet_context_alloc that must be used now to allocate the
2694 context. This also means that if a routine is asynchronous from
2695 silc_[client/server]_packet_parse_type the packet context must
2696 be duplicated by calling silc_packet_context_dup. Otherwise it
2697 gets free'd after silc_[client/server]_packet_parse_type returns.
2698 Also, one must remember that if packet is duplicated then its
2699 reference count must be decresed by calling the free function as
2700 many times as it was duplicated.
2702 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2703 from both client and server.
2705 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2707 * Made joining to a channel working in router environment.
2709 * Cleaned up JOIN command on server side and create function
2710 silc_server_command_join_channel internal routine to make the
2713 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2715 * Changed silc_command_pending list to SilcDList. Also, added
2716 `ident' field to SilcServerCommandPending structure to identify
2717 the reply and to call correct callback.
2719 Added silc_server_command_pending_check function to replace the
2720 corresnponding macro. The silc_command_pending list is not
2723 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2724 to set identifier to previously allocated Command Payload. It
2725 is used to set identifier for command when resending Command
2728 * Added silc_command_payload_encode_payload to encode Command
2729 Payload buffer from SilcCommandPayload structure.
2731 * Added silc_argument_payload_encode_payload to encode Argument
2732 payload buffer from SilcArgumentPayload structure.
2734 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2736 * Changed WHOIS command to support router connection on server side.
2737 The whois request is always sent to router unless the server is
2738 standalone server. After server has received the reply from the
2739 router will it send the reply to the client.
2741 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2742 broadcast received broadcast packet. The function is used only
2743 by router. The broadcast packet is always sent to the router's
2746 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2747 render given ID to printable string, for log files for example.
2749 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2751 * Made basic router to router connections working. At least they
2752 can now connect to each other but nothing really works the way
2753 they are supposed - yet.
2755 * Added new initiator token to RouterConnection configuration
2756 file in silcd/serverconfig.[ch]. It is used to tell whether we
2757 are the initiator to the remote router or whether we'll expect
2758 the other end to connect.
2760 * Moved registering of listener task to silc_server_init, hence
2761 the server starts listenning as soon as it is run, even if it
2762 does not have connections to other routers. Let's see how well
2765 * Changed default connection retry timeouts for more suitable in
2768 * Removed cipher and such arguments from silc_idlist_add_client
2769 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2770 Added new function silc_idlist_add_data to add the keys and stuff
2773 * Added SilcIDListData structure and added it to SilcClientEntry
2774 and SilcServerEntry as their first field in the structure. This
2775 way we can explicitly cast the ID entries to the SilcIDListData
2776 structure and get common data for the entries. In past, we had
2777 to first check what type of connection it is and then cast it to
2778 correct ID entry type. Now, we can directly cast the opaque
2779 pointer to the SilcIDListData (no matter what ID entry it actually
2780 is) and get the data needed.
2782 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2784 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2785 in some circumstances even if threre were timeout tasks, though not
2786 IO tasks, but tasks anyway. Now fixed.
2788 * Defined SilcServerConnection structure to hold connection specific
2789 stuff about directly connected servers and routers. The definition
2790 is currently in silcd/server_internal.h. I thought about having
2791 a bit more important role fro this struct but for now it is used
2792 only when connecting to other server (or router actually).
2794 * Added connecting retry support in server when connecting to
2795 router(s). The retry feature implement exponential backoff
2796 algorithm. Also, added SilcServerParams structure to hold default
2797 parameters for server. For now, it include these retry settings
2798 and are hard coded. After server is moded to be as Silc Server
2799 Library this structure will be more important.
2801 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * Changed client librarys channel->clients table to SilcList and
2804 changed code accordingly.
2806 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2808 * Changed client's channel table to SilcList and changed code
2809 accordingly. Also changed SilcChannelClientEntry to include back-
2810 pointer to the channel so that client entry can use that structure
2811 as list as well and we have fast cross-reference to the channel.
2812 This change dramatically decreased the complexity of channel
2813 handling with client entry and vice versa (removed one extra
2814 loop when searching for channel entry from many functions).
2816 * Changed server->sim from table to SilcDList and changed code
2819 * NAMES command can now be used from user interface. It will show
2820 the user list on the channel, neatly.
2822 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2823 Code now saves realname of the user if it becomes available.
2825 * Renamed configure.in to configure.in.pre and made ./prepare
2826 script to automatically add correct version string to
2827 configure.in which it creates from configure.in.pre.
2829 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * NAMES command reply now shows users mode with the nickname when
2834 * Moved silc_client_ch[u]mode[_char] functions from
2835 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2836 place sucks, they are utility functions and should be in some
2839 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2841 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2844 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2848 * Added TRQ (efficient deque and list library) into lib/trq. This is
2849 a very good list library that is currently used in the SILC. Defined
2850 SilcList API over the library because I didn't like the API very
2851 much. See lib/trq/silclist.h for the API and examples of how to
2852 use the API. Fixed various places in the code to use the new
2853 SilcList API. The SilcList is meant for lists that has a structure
2854 already defined as a list. It is not suitable to add just some
2855 context to the list (in TRQ, the context is the list actually).
2857 So, I defined SilcDList that can be used for the purpose where
2858 predefined list structure does not exit. This can be used as
2859 such list. Now some context just can be added to the SilcDList.
2860 Currently this list is not used in the SILC just yet, though there
2861 are a lot places where this can replace dynamically allocated
2862 tables and I will fix these places, later, to use SilcDList.
2863 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2864 and use TRQ internally).
2866 Also fixed some annoying warning messages that the original TRQ
2867 code generated. Also minor changes to TRQ's Makefile.in.
2869 * Added support for querying by Client ID to both WHOIS and
2870 IDENTIFY commands into server, as required by the protocol.
2872 * Removed method function pointers from SilcBuffer structure. They
2873 weren't used to anything and just increased the context size for
2874 no good reason. This change also made silc_buffer_alloc and
2875 silc_buffer_free functions inline functions.
2877 * Disabled command flooding detection support until it's fixed so
2878 that it accepts commands in but does not execute them more than once
2881 * Added silc_net_localhost(), to return local hostname, into
2882 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2883 that must be initialized before calling silc_client_init.
2885 * Added new function: silc_server_send_notify_on_channels to send
2886 notify messages to all channels client has joined. It is assured
2887 that the message is sent only once per client.
2889 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2890 lib/silcutil/silcutil.[ch] as silc_format function. The new
2891 function is generic and is used by server as well, not only by
2892 the logging routines.
2894 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2895 the provided version string was not acceptable. Added new function:
2896 silc_ske_check_version into lib/silcske/silcske.h. The function
2897 must be implemented by the application (client or server) and it
2898 does not reside in the SKE library. The function checks the version
2899 string remote end sent.
2901 * Added back pointers (to opaque context and to SilcSocketConnection)
2902 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2904 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2905 duplicate packet context structure.
2907 * Changed `notify' client operation to send same arguments as client
2908 receives from server except for ID's. ID's are mapped to correct
2909 ID entry and that is returned. Also, if channel entry is not sent
2910 by server but the notify is for channel the channel entry is sent
2911 to application (otherwise application doesn't know that it is for
2912 channel (library gets it from packet's Destination ID)).
2914 * Added silc_client_remove_from_channels into client library to
2915 remove a client from all channels it has joined to. Used when
2916 received SIGNOFF notify from server. Added also new function
2917 silc_client_replace_from_channels to replace old ID entry with
2918 new ID entry on all channels. Used when received NICK_CHANGE
2921 * Fixed ID Cache list handling in silc_idlist_get_client in
2922 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2923 to get (or query) client by ID.
2925 * Updated TODO list.
2927 * Added connection authentication status message defined by the
2928 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2929 support for these into the code in client and server side.
2931 * Added generic function silc_client_send_command to send any command
2932 with variable argument list. Application should use this function
2933 to send commands if the command functions provided by the library
2934 does not suite for the application's user interface needs.
2936 * Added new `failure' client operation. Application is notified about
2937 received failure packet if client is executing a protocol. In this
2938 case the protocol's execution has failed.
2940 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2941 is required by the protocol.
2943 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2944 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2947 * Added status flag to SilcSKE object to indicate realtime status
2948 of the SKE protocol.
2950 * Application receives now exactly same command reply arguments as
2951 the library receives from server. However, if ID is received the
2952 corresponding ID entry is returned to the application (eg. Client
2953 ID is mapped to correct SilcClientEntry entry and that is returned).
2954 Changed command_reply client operation due to this change.
2956 * Changed all ID's in commands and in command replys as ID Payloads.
2957 Change affected both client and server side codes.
2959 All ID's sent in SILC network (with execption of ID's in SILC
2960 Packet header) are sent in ID Payload to support variable length
2963 * Server now notifies nick changes and notifies all clients on
2964 the channels about the new nickname (about the new Client ID,
2967 * Implemented CMODE command to change channel modes. Supports all
2968 channel modes defined by the protocol specs except ban and invite
2969 lists. (Also, private channel key mode is supported but support for
2970 setting private channel key in client is missing, thus, this mode
2971 has no effect on client side (except that server requires that the
2972 client uses private channel key and normal channel traffic does not
2975 Also, invite mode works per se, but INVITE command does not work
2976 yet correctly, so you can set channel as invite only channel but
2977 inviting clients to the channel does not work (it is yet to be
2978 thought what's the best way to do it).
2980 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2981 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2982 Implemented CUMODE command to change user's mode on the channel.
2983 Supports all modes defined by the protocol specs.
2985 * Added NAMES command reply to return users modes on the channel.
2987 * Removed unnecessary and slow ciphers from lib/silccrypt.
2989 * Set SO_KEEPALIVE option to connection sockets by default.
2991 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2993 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2994 redefined the Notify Payload into protocol specs.
2996 * Added silc_id_payload_parse_id to get ID directly from raw
2999 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3002 accept searching by Client ID as well.
3004 * Added support for LEAVE and SIGNOFF notify types in client library.
3006 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3007 to parse ID Payload from raw data.
3009 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Added flags parameter into silc_ske_assemble_security_properties
3012 function in lib/silcske/silcske.[ch].
3014 * Changed notify client operation to fit better for notify messages
3015 sent by server. The notify payload received from server is now
3016 passed to the application (after parsing it to SilcNotifyPayload).
3017 It is application's responsibility to retrieve the arguments
3018 from the payload and show the message the way it wants. The message
3019 sent by server is implementation specific.
3021 * Changed public keys to comply with the protocol specification.
3022 Old public keys are not supported anymore and are not compatible.
3024 * Removed nickname from Channel Payload as the latest draft removed
3025 it. The client must resolve the nickname from the NAMES command
3026 reply received when it joined the channel.
3028 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3030 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3032 * Fixed some errors in protocol specification drafts.
3034 * Created lib/silccore/silcnotify.c to implement Notify Payload
3035 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3036 generic payloads described by protocol specifications. The file
3037 includes implementations for ID Payload and Argument Payload.
3039 * Changed Command Payload implementation to use the new Argument
3040 Payload. Changed command_xxxx_payload to command_payload_xxxx
3041 to comply with SILC coding conventions.
3043 * Added suppport for Argument Payload handling in Notify Payload
3044 implementation as protocol requires it. Added the new support
3045 into server and client lib as well.
3047 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Added support for multiple nicknames on same channel. [n] is
3050 added locally to the nickname if there are more than one same
3051 nicknames on the channel.
3053 * Server now sends all nicknames that matched WHOIS request.
3054 Client also shows the list received from server.
3056 * Added TOPIC command to client side. User can now set and show
3057 current topic on channel.
3059 * Added MOTD command to client and server. Also, server sends the
3060 motd when client connects to the server.
3062 * Changed version strings to comply ISO 8601.
3064 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Fixed protocol error handling in client library. It should now
3067 cope even if the SKE fails for some reason.
3069 * Made new protocol specification drafts for submitting to IETF.
3071 * Implemented TOPIC command to server in silcd/command.c.
3073 * Added two new notify types into lib/silccore/silcnotify.h:
3074 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3075 notify nickname change and topic setting/change on a channel.
3077 * API change of command_reply operation in client library. The
3078 application gets now the status type received from server as well.
3080 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3082 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3084 * Cras fixed and optimized the packet handling even further and
3085 it should work now. Minor change to the prototype of function
3086 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3088 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * Added new function into lib/silcutil/silcschedule.[ch]:
3091 silc_schedule_with_fd to select() a specified fd. The function
3092 returns after timeout expires or data arrives or goes. The
3093 function is used by packet routines to wait that all data is
3094 received from network.
3096 * Fixed data reading from network in lib/silccore/silcpacket.c.
3097 The code now assures that all data is read from the fd and then
3098 continues packet processing. This was a bug fix since the code
3099 used to drop some data in some circumstances.
3101 * Added new function into lib/silcclient/client.[ch]:
3102 silc_client_start_key_exchange to start key exchange after
3103 connection has been established to server. The code internally
3104 now uses this funtion but its main purpose was to provide it
3105 for applications that perform their own connecting. After
3106 application has created a connection it merely calls this
3107 function to start the key exchange between client and server.
3108 The library takes care of everything else after that.
3110 Updated also lib/silcclient/README to explain the usage of
3113 * Do not send to application information that connection has
3114 been established. Application gets notified it by connect
3117 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Applied cras's patch to add silc_schedule_one function. The
3120 function runs scheduler once and returns.
3122 * Fixed the scheduler after cras messed it up. The timeout
3123 handling works now as it's supposed to work.
3125 * Added into lib/silccore/ silcnotify.h to include notify
3126 message types support. Changed silc_server_send_notify*
3127 functions, in server.[ch], to support those new notify types.
3128 Added the support for the notify types into client library,
3129 as well. Added new notify client operation into ops.h in
3132 * Changed silc_server_packet_send_to_channel to send normal
3133 packets instead of just channel message packets. The function
3134 is now used to send the notify packets to channels. It is not
3135 used to send channel message packets anymore, as server never
3138 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3139 va_arg()s as it seems to require it nowadays. I guess, if SILC
3140 is compiled with older va_arg() the new code should work anyway.
3142 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Splitted core library. Core library (lib/silccore) includes
3145 now only SILC protocol specific core (and common) components.
3146 Created new utility library (lib/silcutil) that includes more
3147 generic purpose stuff. The stuff for util library was taken
3148 from the old core library. This was minor and easy split.
3150 * Created SILC Client Library (lib/silcclient) that includes
3151 implementation of the SILC client without user interface. This
3152 was major move from silc/ directory. The code has been changed
3153 so that it is transparent towards the user interface. The
3154 silc/ directory includes now the same user interface as before
3155 and it uses the new client library. Read lib/silcclient/README.
3156 Basicly, the client library performs everything else related
3157 to SILC except user interface handling. Also, configuration
3158 files are considered to be part of user interface and library
3159 does not handle them.
3161 This change also changed a lot of structures, function naming etc.
3162 Most important change was that SilcClientWindow object was
3163 renamed to SilcClientConnection in the client library. Created
3164 also new file lib/silcclient/ops.h. Also added new files
3165 silc/local_command.[ch] and silc/client_ops.[ch].
3167 All these changes were made to make it easier for user interface
3168 designers to create what ever user interface for the SILC client
3171 It is also expected that the server will be moved to lib
3172 directory as well and SILC Server Library will be created;
3173 sometimes in the future.
3175 * Removed Local commands from lib/silccore/silccommand.h as
3176 they are application specific and new client library does not
3177 handle any of those anymore.
3179 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3180 old client implementation in silc/.
3182 * Added support for callback functions in SILC_LOG_* macros.
3183 Application can now set its own callbacks that will be called
3184 instead of using the default functions that will always print
3185 the debug messages to stderr (or stdout). Also, debugging can
3186 now be disabled by setting silc_debug to FALSE and re-enabled by
3187 setting it to TRUE. Note, that logging will still work even
3188 if debugging is disabled.
3190 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3191 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3192 silc_log_reset_debug_callbacks.
3194 * To enable debugging in silc client one must give now -d
3195 option on command line.
3197 * Changed silc_schedule_init to automatically allocate task queues
3198 if they are not allocated before calling it.
3200 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3202 * Added GMP 3.1 into math library.
3204 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3207 a channel in SILC network. The packet is used by servers and
3208 routers to notify other routers that user has left a channel.
3209 This little feature was missing until now. Added the feature
3210 to protocol specification as well.
3212 Added functions: silc_server_send_remove_channel_user and
3213 silc_server_remove_channel_user into server.[ch].
3215 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3216 lib/silccore/silcpacket.h. However, they are not implemented
3219 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3221 * Fixed joining to a channel and sending channel messages
3222 between server and router. The channel message sending should
3223 now work inside a cell.
3225 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Fixed the private message sending between server and router.
3228 The private message sending should now work inside a cell.
3230 * Added silc_server_replace_id into server.[ch] to replace
3231 existing ID in the SILC network.
3233 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3234 and silc_idlist_replace_server_id into idlist.[ch] in server.
3236 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3238 * Fixed the server to server connections. Server can again now
3239 connect to router. Router to router connections probably does
3242 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * Added dynamic protocol registering support. Now protocols can
3245 registered and unregistered on the fly. Patch by cras.
3247 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Added lib/contrib directory to hold routines that some platforms
3250 don't have but are needed by SILC.
3252 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3253 into lin/contrib to provide getopt() and getopt_long() for
3254 those who don't have it.
3256 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Added AWAY command to client. When away message is set and
3259 client receives a private message packet the client automatically
3260 replies to the sender with the away message.
3262 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3263 bug seemed to be the cause of recent problems when compiling
3266 * Added version detection support to SKE protocol specification
3267 and added the new changes to the SKE implementation as well.
3268 There were other minor changes in the SKE protocol as well.
3270 Many changes in lib/silcske/silcske.[ch] and in
3271 lib/silcske/payload.[ch].
3273 * Added ^U functionality, clear input line. Patch from cras.
3275 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3277 * Mainly small bugfixes on core library. Fixed some debugging
3278 logging and buffer overflow in silclog.c.
3280 * Updated config.sub and config.guess on the distribution tree.
3282 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Added command lagging support in server. Client may execute
3285 commands now only once in two seconds.
3287 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3289 * Optimized packet reception. MAC computation and checking is now
3290 also more optimized. A lot previously duplicated code is now
3291 used as generic by both client and server.
3293 * Fixed key pair generation in clientutil.c
3295 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3297 * Added into lib/silccore/silcbufutil.[ch] new function;
3298 silc_buffer_realloc.
3300 * Moved generic packet sending/encryption functions to
3301 lib/silccore/silcpacket.[ch] from client and server. Some
3302 rewriting of the functions.
3304 * Moved all generic packet reception/decryption functions to
3305 lib/silccore/silcpacket.[ch] from client and server. The
3306 packet processing is now much cleaner in both client and server.
3307 These were major changes in both client and server.
3309 * Created many common functions in server to do packet sending.
3310 Previously code were duplicated a lot, this has been removed
3313 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3315 * Rewrote major parts of the ID cache system. Don't know
3316 whether it is better now or not but at least the API is more
3319 * Major rewrite on ID cache stuff on client because of the ID
3320 cache API changes. Added idlist.c to client.
3322 * Also major rewrite on ID cache stuff on server as well.
3323 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3324 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3325 in hand, instead they are all put into the ID cache system now.
3326 All server_idlist_* routines uses ID cache now instead of
3327 traversing its own lists (those lists does not exist anymore).
3328 SilcIDList though still exists. Also, SilcXXXEntry's are
3331 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Finally made the SKE implementation compliant to the protocol
3334 specification. All mp integers are now binary encoded as
3335 opposed being HEX encoded.
3337 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3340 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3341 functions: silc_[encode/decode]_pem. Also added function
3342 silc_encode_pem_file to PEM encode with newlines ('\n') for
3345 * SILC public keys are now encoded either PEM or binary. Same
3346 option is for private keys as well. By default private keys
3347 are binary encoded and public keys PEM encoded. Silly HEX
3348 encoding were removed.
3350 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3351 function to create fingerprints.
3353 * Fixed a bug in SHA1; does not change the original data anymore.
3355 * Partly implemented INFO command on client and server side.
3356 Fixed CLEAR command. Changes to SERVER command; show current
3357 server(s) when giving command without arguments. Added
3358 VERSION command to client.
3360 * Added check to server that unregistered connections cannot
3361 execute commands (unless it is specificly allowed).
3363 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3365 * Fixed screen refresh.
3367 * Fixed channel joining bug from client. On some circumstances
3368 client tried to join to a channel it had already joined.
3370 * Added public key verification process into client's protocol.c.
3371 The client now verifies the public key from user and saves
3372 it into ~./silc/serverkeys/ directory.
3374 Added into: clientutil.[ch]: silc_client_verify_server_key.
3376 * Changed SKE protocol's silc_ske_initiator_finish function
3377 to accept callback function that verifies the received public
3378 key. Removed old silc_ske_verify_public_key function.
3380 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3382 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3383 silc_pkcs_private_key[_data]_set.
3385 * Made the password and public authentication more cleaner in
3386 server's protocol.c.
3388 * Removed historic and obsolete protocol `channel_auth' from
3389 both client and server.
3391 * Removed wrong way of sending command status messages from
3392 server to client in server's command.c. The old way violated
3393 protocol specification.
3395 Changes to silccore/silccommand.[ch]: removed
3396 silc_command_encode_status_payload -> not needed anymore,
3397 changed silc_command_encode_payload_va to accept extra
3398 argument on variable argument list. The argument type must
3399 now be provided to the function. Also, added new function:
3400 silc_command_encode_reply_payload_va which is same as
3401 normal command_encode_payload_va except command status type
3402 is provided as extra argument.
3404 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * Added ~./silc directory handling. The directory includes the
3407 public and private keys for the client.
3409 Added silc_client_check_silc_dir, silc_client_create_identifier
3410 and silc_client_load_keys.
3412 * Implemented SILC protocol compliant public key. Added public
3413 and private key saving to and loading from files.
3415 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3416 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3417 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3418 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3419 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3421 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3422 silc_pkcs_load_[public/private]_key.
3424 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Added silc_server_get_route (route.[ch]) to get connection
3427 data for the fastest route for given ID.
3429 * Implemented INVITE command on client and server. The command
3430 were re-defined in the SILC Protocol Specification and the
3431 implementation now complies with the specification.
3433 * Implemented PING command on client and server.
3435 * Implemented NAMES command on client and server. The server side
3436 supports currently only normal server not router server yet.
3437 Some changes to NAMES definition in SILC protocol specification.
3439 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3441 * Implemented LEAVE command on client and server.
3443 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3444 again. This change was made to the protocol as well. Server
3445 should not violate the protocol specification anymore.
3447 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3450 was tested. SOCKS4 was not but should work anyway.
