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. Same also when
5 creating new key pair with -C option.
7 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
9 * Fixed the silc_verify_public_key client operation function to
10 save the public keys differently. The fingerprint is now
11 used as filename and not the hostname. This way also the
12 client keys are saved uniquely and not with hostnames. The
13 affected file is silc/client_ops.c.
15 * Trimmed the silc_hash_fingerprint function to remove extra
16 whitespaces from the end of the fingerprint. The affected
17 file is lib/silccrypt/silchash.c.
21 * Added silc_cipher_register_default function to register all
22 default ciphers. It can be used when configuration files
23 does not exist and the application does not want any specific
24 ciphers in any specific order.
26 The SilcDList is now used as silc_cipher_list dynamically
27 allocated cipher list. Removed the static list all together
28 and now all ciphers must be allocated to the dynamic list.
29 The silc_cipher_alloc routine was changed to check only the
32 All silc_cipher_* routines that used to return int returns
35 The affected files lib/silccrypt/silccrypt.[ch].
37 * The same thing was done to silc_hash_* as for silc_cipher_*
38 routines. Affected files lib/silccrypt/silchash.[ch].
40 * The same thing was done to silc_pkcs_* as for silc_cipher_*
41 routines. Affected files lib/silccrypt/silcpkcs.[ch].
42 Added also silc_pkcs_[un]register[_default] functions.
43 Removed the data_context from the PKCS API.
45 * Added silc_hmac_register_default function to register default
46 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
47 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
48 to unregister all hmacs at once.
50 * Register the default ciphers, hash functions, PKCSs and HMACs
51 if client's configuration file does not exist. The affected
54 * The client did not load the hash functions from the SIM
55 modules at all. Added support for this. Affected file is
58 * When decoding public key with silc_pkcs_public_key_decode, check
59 the supported algorithm only if PKCS are registered. Affected
60 file lib/silccrypt/silcpkcs.c. The same was done with the
61 silc_pkcs_private_key_decode.
63 * Fixed the SILC List routines to keep the list always in order.
64 It used to change the list's order when traversing the list but
65 not it preserves the order. Affected file lib/trq/silclist.h.
67 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
69 * Added the client library to use the SilcSocketConnection's
70 reference counter (by silc_socket_dup) to prevent the bug that
71 the socket object may be freed underneath async operation.
73 * The name resolv library checking fixes in the configure.in.pre.
76 * Created new version of the protocol drafts for future
77 development. The -03 drafts are the ones that will be changed
78 in the trunk now and the -02 will remain as they are.
80 * Send list of CUMODE notifys to the router when announcing
81 the channel users to the router. Affected file silcd/server.c.
82 If the router receiving channel founder CUMODE for a channel
83 that already has channel founder it will send CUMODE notify
84 to the sender to remove the channel founder rights from the
85 announced client. Affected file silcd/packet_receive.c.
87 * The CUMODE notify may now use Server ID as well as the entity
88 who changes the mode. Updated protocool specs.
90 * Updated INSTALL and README files.
92 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
94 * New web pages in the http://silc.pspt.fi. The pages was
99 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
101 * Implemented the [DenyConnectin] config section in the server.
102 Added silc_server_config_denied_conn to check whether incoming
103 connection is denied. Affected file silcd/serverconfig.[ch].
105 * Do not check the ports when checking the incoming configuration
106 data if the port is 0, meaning any. Affected file is
107 silcd/serverconfig.c.
109 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Fixed buffer overflow in silc_string_compare in the file
112 lib/silcutil/silcutil.c.
114 * Fixed double free in silc_server_command_leave in the file
117 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
119 * Fixed the version checking in the server. Affected file is
122 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
124 * Fixed the configuration data fetching when accepting new
125 connections in the server. Affected file silcd/server.c.
127 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
129 * Added `sender_entry' argument to the function
130 silc_server_packet_relay_to_channel so that we can check
131 whether some destination actually belongs to the same route
132 the sender belongs (ie, we must not resend the packet to the
133 sender). Affected file silcd/packet_send.[ch].
135 * Added `servername' field to the SilcClientEntry in the server
136 to hold the name of the server where client is from. Affected
137 file is silcd/idlist.h.
139 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Moved the channel message encrypting in the router betwen
142 router connections from silc_server_channel_message to the
143 silc_server_packet_relay_to_channel since we want to check
144 whether we have anybody channel before encrypting anything.
145 Affected files silcd/packet_[receive/send].c.
147 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
149 * Fixed the [AdminConnection] server config section to support
150 multiple entries. Affected file silcd/serverconfig.c.
152 * Added support into the server to check the validity of the
153 incoming connection before executing any KE or authentication
156 * The connection configuration is now saved to the KE and
157 connection auth protocol contexts and not fetched anymore in
158 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
160 * The local hosts listenning address and port is also resolved
161 now when starting the server. We want to have the socket object
162 to include the real address and port for the listener. Added
163 new function silc_net_check_local_by_sock into the files
164 lib/silcutil/silcnet.[ch].
166 * Fixed a broadcast bug in server -> do not broadcast if we
169 * Fixed a routing bug. Do not route broadcast packets ever.
170 Broadcast packets must be processed always and not routed since
171 they may be destined to some other host than yourself and thus
172 would get routed without no good reason. Affected file is
175 * Added function silc_server_config_is_primary_route to check
176 whether primary router connection has been configured (a router
177 configuration that we are initiating). If there is not, we
178 will assume that there is only two routers in the SILC network
179 and we will use the incoming router connection as our primary
180 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
182 * Changed the order of the broadcasting. Broadcast _after_ the
183 packet has been processed not before. Affected file is
186 * Fixed a [ClientConnection] parsing bug. The port was never
187 parsed correctly thus resulting to port 0. Affected file
188 silcd/serverconfig.c.
190 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
191 argument and did not set the broadcast packet flag. Affected
192 file silcd/packet_send.c. Fixed same bug in the function
193 silc_server_send_notify as well.
195 * If we receive NEW_ID packet for our own ID in the server, ignore
198 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
202 * Removed the nickname from the Private Message Payload.
203 Updated the code and the protocol specs.
205 * Updated protocol specs for submitting to the IETF.
207 * Tweaked the Random Number Generator a bit. Affected file
208 lib/silccrypt/silcrng.c. Exported a new function
209 silc_rng_[global]_add_noise which can be used to add more
212 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
214 * Do not parse packets with different timeout when protocol
215 is active -> may cause problem with rekey. Affected file
218 * When server receives signoff notify it must not create
219 new channel key if the client is on any channels since the
220 sender of the signoff notify will create it.
222 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
224 * Added printing of error messages during SKE protocol from the
225 failure packet sent by server during SKE. Affected file
228 * Removed the client's failure_callback handling with timeout
229 and handle it immediately when received.
231 * The SKE library returned wrong type in SUCCESS and FAILURE
232 packets. They must be 32 bit MSB not 16 bit MSB.
234 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Ok, rewrote the logic of the re-key and now it seems to work.
237 I tested it on high traffic with frequent re-keys without
238 problems. Added hmac_receive (and renamed hmac to hmac_send)
239 in SilcClientConnection in lib/silcclient/client.h and
240 in SilcIDListData in silcd/idlist.h. Also, removed the
241 SilcPacketParserContext's cipher and hmac fields as they are
242 not needed anymore and actually caused some problems when
243 the ciphers and hmac's changed underneath the packet parser.
245 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
247 * If re-key protocol is active then process the incoming packets
248 synchronously since we must assure that icoming packets encrypted
249 with the old key is processed before the new keys is set to
250 use. This is true other packets than for REKEY packets.
251 Affected file silcd/server.c. The same was done to client library
252 as well, affected file lib/silcclient/client.c.
254 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
256 * Fixed bug in client and server to accept the force send if
257 the packet is send from silc_[server/client]_packet_process
258 function. Otherwise the packets are never delivered, oops.
260 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
262 * Disable force sending of packets when REKEY protocol is active.
263 We must assure that no packet is sent directly when rekey is
264 performed. All packets must be sent through packet queue.
265 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
266 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
267 function is silc_[server/client]_packet_send_real to check
270 * Replaced the SIM paths from example config files to
271 /usr/local/modules. Also, make install creates now
272 /usr/local/silc/logs directory to hold all the SILC server
275 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * Made the configure.in.pre work on Solaris. Patch by salo.
279 * Made all ciphers compatible with non-x86 machines. Defined
280 CBC mode macros into lib/silccrypt/ciphers_def.h.
282 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
284 * Fixed the make install.
286 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * When MAC computation fails the silc_packet_decrypt returned 0
289 even though it was supposed to return -1. Fixed this. The
290 affected file is lib/silccore/silcpacket.c.
292 * Do not replace the config files in /etc/silc (in make install)
293 if they already exist. Affected file ./Makefile.am.
295 * Do not send re-key packets immediately but through packet queue.
296 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
298 * Changed silc_net_check_host_by_sock to return FALSE if the
299 IP/DNS could not be resolved. Though, it returns the IP address
300 now even if it could not resolve it (but returns also FALSE).
301 Affected file lib/silcutil/silcnet.[ch].
303 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
305 * Added silc_pkcs_decode_identifier to decode the public key's
306 identifier. Affected file lib/silccrypt/silpkcs.[ch].
307 Added also silc_pkcs_free_identifier. Added also new context
308 SilcPublicKeyIdentifier.
310 * Added -S option to the silc client. It is used to dump the
311 contents of the specified public key file.
313 * Changed the PKCS api to return the public key length when
314 setting the public key.
316 * Fixed a fatal bug in the public and private key file loading.
317 Affected file lib/silccrypt/silcpkcs.c.
319 * Execute the packet parsing for client with zero (0) timeout
320 if the protocol is active. Affected file silcd/server.c.
322 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
324 * Made the key generation options to the silcd program. Added
325 -C option, equivalent to client's option.
327 * Added new [ServerKeys] config section to the server. It
328 configures the server's public and private key.
330 * Defined generic Public Key Payload into the protocol
331 specification to send specific type of public keys and
334 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
335 public key or certificate.
337 * Implemented the GETKEY command to the server and to the
338 client library and on user interface.
340 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
342 * Made preliminary `make install' work.
344 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
346 * Added SilcServerRekey context into silcd/idlist.h.
348 * Added the PFS support as defined in the specification to the
349 SKE protocol. Affected files lib/silcske/*.c.
351 * Added `ske_group' field to the SilcServerRekey context to hold
352 the number of the SKE group that is used with PFS in re-key.
353 Affected file silcd/idlist.h.
355 * Added PFS re-key support to the server. Affected file is
358 * Added silc_protocol_cancel to cancel execution of the next
359 state of the protocol. Affected file is
360 lib/silccore/silcprotocol.[ch].
362 * Added the re-key support with and without PFS to the client
363 library. Re-key is performed once in an hour, by default.
365 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
366 Added silc_client_rekey_callback and silc_client_rekey_final.
367 Affected files are lib/silcclient/protocol.[ch] and
368 lib/silcclient/client.[ch].
370 * Removed the `hmac_key' and `hmac_key_len' fields from the
371 SilcClientConnection structure; not needed. Affected file is
372 lib/silcclient/client.h.
376 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
378 * Do not ask whether user wants to use the negotiated private key
379 for private messages, just use it. Affected file is
380 silc/local_command.c.
382 * Added `send_enc_key' and `enc_key_len' fields to the
383 SilcIDListData structure since they are needed in the re-key
384 phase. Affected file is silcd/idlist.[ch].
386 * Implemented the simple re-key protocol into the server.
387 Affected files silcd/server.c and silcd/protocol.[ch]. The
388 re-key will be performed once in an hour, by default.
390 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
391 Added silc_server_rekey, silc_server_rekey_callback and
392 silc_server_rekey_final.
394 * Removed Tunneled flag from the protocol. Updated the code
395 and the specifications.
397 * Adde `pfs' field to the SilcIDListData to indicate whether
398 the PFS is to be performed in the re-key. Affected file is
401 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
403 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
404 int64 of at least the xintXX size. If void * is less that 4
405 bytes uint32 * will be used. Defined bool as boolean.
407 * Changed _ALL_ unsigned long and unsigned int to uint32,
408 unsgined short to uint16 in the source tree.
410 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
411 not handle clients that has entry->data.registered == FALSE.
412 They are not in the network anymore. Affected file is
415 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
417 * Implemented the sending of the SERVER_SIGNOFF notify in the
418 server. Affected file is silcd/server.c.
420 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
421 Added also silc_notify_payload_encode_args into the
422 lib/silccore/silcnotify.[ch].
424 * Implemented ther SERVER_SIGNOFF notify handling in the server.
425 Affected file silcd/packet_receive.c.
427 * Implemented the SERVER_SIGNOFF notify handling in the client
428 library. Affected file lib/silcclient/client_notify.c. Also,
429 implemnted the printing of the SERVER_SIGNOFF info to the
430 application. Affected file silc/client_ops.c.
432 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
433 if the deleting was successful. Affected file silcd/idlist.[ch].
435 * Added support for public key authentication in the connection
436 authentication protocol in the client library. Affected file
437 lib/silcclient/protocol.c.
439 * Changed the server's silc_idlist_get_clients_by_* interface
440 to support already allocated array so that new entries may be
441 added to pre-allocated array. Affected file silcd/idlist.[ch].
442 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
445 * All command reply functions in the server now calls the
446 pending command callback even if error occured. This way the
447 error will be delivered to the client as well. Affected files
448 silcd/command.c and silcd/command_reply.c.
450 * Fixed INFO command to return local server's info if no server
451 was provided. Affected file lib/silcclient/command.c.
453 * Removed RESTART command for good. Updated the code and the
456 * Rewrote parts of the task system. It is a bit simpler now.
457 Removed unsued task priorities. The affected files are
458 lib/silcutil/silctask.[ch].
460 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
462 * Moved the USERS printing from the library to the application.
463 Affected files lib/silcclient/command.c and silc/client_ops.c.
465 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
469 * Added channel key re-key support. The re-key is perfomed
470 only by the router and is done once in an hour. Added `rekey'
471 field to the SilcChannelEntry in the server. Affected files
472 silcd/server.c and silcd/idlist.h.
474 * Added silc_task_unregister_by_context into the file
475 lib/silcutil/silctask.[ch].
477 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
479 * Added SILC_UMODE_GONE mode to indicate when the client is not
480 present in the SILC network. Added also support to the local
481 command AWAY that will set this mode. Added support of showing
482 "xxx is gone" in WHOIS command. The USERS command shows the
485 * Fixed setting server and router operator privileges in the
486 server's UMODE command. Affected file silcd/command.c.
488 * Merged the SKE KE1 and KE2 payloads into one payload. The
489 new KE payload is equivalent to the old KE2 payload.
491 Cleaned up the SKE Start Payload parsing. It now uses the
492 simple buffer unformatting to do the parsing. A lot faster
495 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
496 to the SKE that is used to indicate whether both of the SKE
497 parties should perform authentication. By default only the
498 responder performs authentication. By setting this flag also
499 the initiator must do authentication. By default it is unset
500 since in normal SKE case, client to server connection, only
501 the responder should do authentication. When doing SKE between
502 two clients both should perform authentication. Updated the
503 code and the protocol specs.
505 * A little fix to IDENTIFY command in the server. Search the
506 client first by hash not nickname. Affected file is
509 * Fixed the silc_client_close_connection to support closing
510 the client to client connections wihtout deleting too much
511 data. Affected file lib/silcclient/client.c.
513 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
514 are received if protocol used to be active but is not anymore
515 the application would crash due to NULL pointer dereference.
516 Affected files silcd/server.c and lib/silcclient/client.c.
518 * Added `hash' field to the SilcClientConnection to include
519 the hash function negotiated in the SKE protocol.
521 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
522 to set the channel founder authentication data. A client can
523 claim the founder rights later by providing the authentication
524 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
525 This way the channel founder can regain the channel founder
526 privileges even it is left the channel. This works only on
527 local server and the client must be connected to the same
528 server to be able to regain the founder rights. Updated the
529 protocol specs accordingly.
531 Added support to the CMODE command in the client to set the
532 founder auth data. Read the README to see how to set it.
534 Added support to the CUMODE command to claim the founder
535 rights. Read the README to see how to do it.
537 Added support for the founder authentication to the Channel
538 Entry in the server. Affected file silcd/idlist.h.
540 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
541 server's CMODE command. Affected file silcd/command.c.
543 * Added the following new functions into lib/silccore/silcauth.[ch]:
544 silc_auth_get_method and silc_auth_get_data.
546 * The server now saves the remote hosts public key to the
547 SilcIDListData pointer. Affected file silcd/protocol.c.
549 * The normal server now does not remove the channel entry from
550 the cache if the founder authentication data is set. It used
551 to remove it if the founder was the last one on the channel on
552 the server and left the channel. The auth data is saved and
553 if the channel is re-joined later the old entry is used with
554 the old auth data. Affected files silcd/command_reply.c and
557 * Removed the `pkcs' field from the SilcIDListData structure
558 in the server; it is not used. Affected file silcd/idlist.h.
560 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
562 * Fixed packet processing on slow links. Partial packets were
563 never re-processed because the incoming data buffer was cleared
564 by the application. Application must not directly clear the
565 sock->inbuf, the packet processing routines handle it. Fixed
566 this in client library and in server.
568 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
570 * Fixed the WHOIS and IDENTIFY send reply function to really
571 check whether to send list or just one entry. Affected file
574 * Cleaned up the LEAVE command's channel key distribution. The
575 affected file silcd/command.c.
577 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
578 can enforce the channel mode as well. In that case the ID
579 includes the ID of the server. The code now enforces the
580 mode change if the router have different mode than the server.
582 * The notify client operation with CMODE_CHANGE notify can now
583 return NULL client_entry pointer if the CMODE was not changed
584 by client. Application must check for this.
586 * Added <Server ID> argument to INFO command to support server
587 info fetching by Server ID.
589 * Added silc_server_announce_get_channel_users to get assembled
590 packets of channel users of the specified channel. Affected
591 file silcd/server.[ch].
593 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
594 was freed underneath the ID Cache.
596 * Re-announce clients when the server received CHANNEL_CHANGE
597 notify from the router. Affected file silcd/packet_send.c.
599 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
602 crashed since it did not handle the fact that there is no cipher
603 called "3" and didn't check the error condition. Now fixed.
605 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
606 flag. It can be used to send message requests.
608 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
610 * Implemented the RESTART command in the client.
612 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
613 notice type messages. Added notice printing to the user
616 * The channel keys are not re-generated if the channel's mode
617 is PRIVKEY, ie private key on the channel exists. Affected
618 files silcd/server.c and silcd/command.c.
620 * Fixed a little bug in channel message delivery when channel
621 private keys are set in the server. Affected file is
624 * Changed the setting on channel->on_channel = TRUE from the
625 silc_client_save_channel_key to the JOIN command reply. The
626 key payload is not received if the private channel key is set.
627 Affected file lib/silcclient/command_reply.c and the
628 lib/silcclient/client_channel.c.
630 * When the CMODE_CHANGE notify is sent and the channel private
631 key mode is removed the channel key must be re-generated in
632 other cells as well. Added this support for the router in the
633 silcd/packet_receive.c.
635 * Added new local command NOTICE to send notice message on
636 channel. Affected file silc/local_command.[ch].
638 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Added new local command ME to the client. It is used to send
641 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
642 some action. Affected file silc/local_command.[ch].
644 * Changed channel_message and private_message client operations
645 to deliver the message flags to the application. Added also
646 the `flags' arguments to the silc_client_send_channel_message
647 and silc_client_send_private_message functions. Affected file
650 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
652 * Redefined the Private Message Payload to support private message
653 keys and to support the new private message flags. Updated
654 the protocol specs. Flags makes it possible to have for example
657 * Added new type SilcPrivateMessagePayload and defined an API
658 for it in the lib/silcclient/silcprivate.[ch].
660 * Tested private message private keys successfully. Tested the
661 private message key set, unset and list commands with the new
664 * Redefined the Channel Message Payload to include the channel
665 message flags (equal with private message flags) to support
666 for example CTCP style messages.
668 * Defined some of the message (for channel and private message)
669 flags. Updated the protocol specs and added the flags to the
670 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
672 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
674 * Added SilcKeyAgreementStatus type to the key agreement routines
675 to indicate the current status and error if one occured.
676 The status types are defined in the lib/silcclient/silcapi.h.
678 * Added new local command KEY that is used to set and unset private
679 keys for channels, set and unset private keys for private messages
680 with remote clients and to send key agreement requests and
681 negotiate the key agreement protocol with remote client. The
682 key agreement is supported only to negotiate private message keys,
683 it currently cannot be used to negotiate private keys for channels,
684 as it is not convenient for that purpose.
686 * Fixed a minor pending callback setting bug in the function
687 silc_client_get_client_by_id_resolve, now the function works.
688 Affected file lib/silcclient/idlist.c.
690 * Added function silc_net_get_local_port to get local bound
691 port by socket. Added to lib/silcutil/silcnet.[ch].
693 * Added `sockets' and `sockets_count' fields to the SilcClient
694 object. They hold the sockets of the listenning sockets in
695 the client. Listenning sockets may be for example the key
696 agreement server. Affected file lib/silcclient/client.[ch].
697 Added functions the silc_client_add_socket and the
698 silc_client_del_socket. They are exported to the application
701 * Added ~./silc/clientkeys to support other client's public keys.
703 * Renamed verify_server_key client operation to verify_public_key
704 and added one argument to indicate the type of the connection
705 (server, client etc.).
707 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Added silc_server_connection_auth_request to handle the
710 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
711 silcd/packet_receive.[ch].
713 * Added silc_server_send_connection_auth_request into the
714 silcd/packet_send.c to send the connection auth request packet.
716 * Cleaned up the silcd/protocol.c a bit and fixed some memory
719 * Fixed the public key authentication in responder side in the
720 server. The `auth_data' pointer includes the SilcPublicKey
721 not the path to the public key. Affected file silcd/protocol.c.
723 * Implemented the public key authentication in the initiator side
724 in the server. Affected file silcd/protocol.c.
726 * Removed the [RedirectClient] config section from the server
727 configuration. Is not needed and I don't want to implement it.
729 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
731 * Cleaned up the CMODE command in the server. It now works
732 correctly and supports all the modes defined in the protocol.
733 Affected file is silcd/command.c.
735 * Added `hmac_name' field to the SilcChannelEntry in the server
736 to hold the default HMAC of the channel. It can be set when
737 creating the channel (with JOIN command). Affected files
740 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
741 type to indicate the change of the current cipher and hmac
742 on the channel. Client can safely ignore the <cipher> argument
743 (if it chooses to do so) since the CHANNEL_KEY packet will
744 force the channel key change anyway. The <hmac> argument is
745 important since the client is responsible of setting the new
746 HMAC and the hmac key into use.
748 * Fixed the CMODE command in the client library as well.
750 * Tested CMODE command in router environment successfully.
752 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
754 * Show the version of the remote client (or server) when connecting
755 to the server. It is logged to the log file. Affected file
758 * Fixed the KILLED notify handling in the client library. The
759 client must be removed from all channels when receiving the
762 Also, do not remove the client entry when giving the KILL
763 command but when the KILLED notify is received.
765 * Removed silc_idlist_find_client_by_nickname from the server.
766 Not needed anymore. Affected files silcd/idlist.[ch].
768 * Implemented the CHANNEL_CHANGE notify type handling to the
769 server. Affected file silcd/server.c.
773 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

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

825 * Redefined parts of the SilcChannelEntry in the server to support
826 the new ban and invite lists.
828 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
830 * Redefined the INVITE command. The same command can be used to
831 invite individuals to the channel but also to manage the invite
832 list of the channel (to add to and remove from the invite list).
833 Updated the protocol specs.
835 * Added new command SILC_COMMAND_BAN that can be used to manage
836 the ban list of the channel. Updated the protocol specs.
838 * Removed the channel modes: the SILC_CMODE_BAN and the
839 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
840 in the CMODE command. The equivalent features are now available
841 using INVITE and BAN commands. Updated the protocol specs.
843 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
844 in the network about change in the current ban list. The notify
845 type is not used by the client.
847 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
848 support the invite lists.
850 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
852 * Added new function silc_string_regexify that converts string
853 including wildcard characters into regex string that can
854 be used by the GNU regex library. Added into the file
855 lib/silcutil/silcutil.[ch].
857 Added silc_string_regex_combine to combine to regex strings
858 into one so that they can be used as one regex string by
859 the GNU regex library. Added into the file
860 lib/silcutil/silcutil.[ch].
862 Added silc_string_regex_match to match two strings. It returns
863 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
865 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
867 * Imported GNU regex to the soruce tree into lib/contrib.
868 Fixed some compiler warning from the regex.c.
870 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
872 * Fixed MOTD command in the server to work in router environment.
874 * Fixed the MOTD command in the client library to support
875 the server argument in the command.
877 * Added `nickname_len' argument to the silc_idlist_add_client
878 in the server, as the `nickname' argument may be binary data
881 * Added silc_idlist_get_channels to return all channels from
884 * Implemented LIST command to the server. Affected file is
887 * Implemented the LIST command to the client library and on the
890 * Added [<user count>] argument to the LIST command reply.
891 With private channels the user count is not shown.
893 * Updated TODO and README.
895 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
897 * The client entry's data.registered must be TRUE even with
898 global client entry on global client list. The data.registered
899 is used to check whether the client is anymore in the network,
900 for example with WHOWAS command so it must be valid.
902 * Fixed the WHOWAS command in the server. It now actually works
903 in router environment. Added function into silcd/command_reply.c
904 silc_server_command_reply_whowas_save.
906 * Added silc_idlist_purge function to the silcd/idlist.c
907 to periodically purge the ID Cache.
909 * Fixed INFO command in the server. It works now in router
910 environment. Added <server name> argument to the INFO command
911 reply. Updated the protocol specs.
913 * Fixed minor bug in silc_idcache_purge to not purge if the
914 expire value is zero.
916 * Fixed various bugs in WHOIS and IDENTIFY command handling as
917 they were buggy because of the WHOWAS information.
919 * Fixed local command MSG to handle the async resolving of
920 the remote client properly. It used to fail the first MSG.
921 Affected file silc/local_command.c.
923 * Added `data_len' field to SilcIDCache context.
925 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
927 * Update TODO. Todo in commands in the server.
929 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
931 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
932 used by routers as broadcast packet to inform other routers
933 about the changed user mode.
935 Implemented the notify handling in the server. Affected file is
936 silcd/packet_receive.c. Added the function
937 silc_server_send_notify_umode to the silcd/packet_send.[ch].
939 * Added new generic Channel Payload and deprecated the New Channel
940 Payload. The New Channel Payload is now the generic Channel
943 * Added new argument `mode' to the silc_server_send_new_channel
944 as it is required in the Channel Payload now.
946 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
947 and created a new and real SilChannelPayload to represent the
948 new generic Channel Payload. Implemented the encode/decode
949 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
951 * Added silc_server_get_client_channel_list to return the list
952 of channels the client has joined for WHOIS command reply.
953 Affected file silcd/server.[ch].
955 * Implemented the channel list sending in the WHOIS command reply
956 in server and in the client.
958 Implemented the channel list displaying on the user interface
959 as well. Affected file silc/client_ops.c.
961 * Added silc_channel_payload_parse_list to parse list of Channel
962 Payloads. It returns SilcDList list of SilcChannelPayloads.
963 Client for example can use this function to parse the list of
964 channels it receives in the WHOIS command reply. The caller
965 must free the list by calling silc_channel_payload_list_free.
966 Affected files lib/silccore/silcchannel.[ch].
968 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
970 * Added one new argument <user mode> to the WHOIS command reply
971 to return the mode of the user in SILC. Updated the protocol
974 Implemented it to the server and client.
976 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
978 * Fixed the mode printing on the user interface on joining.
979 Affected file silc/client_ops.c.
981 * Implemented the UMODE command and user modes in general to the
982 client library and to the user interface.
984 * Implemented the UMODE command to the server.
986 * The server now sends UNKNOWN_COMMAND error status if client sends
987 unknown command. Affected file silcd/command.c.
989 * All server commands now handle the command identifier the right
990 way when sending the command reply to the client. The client can
991 use to identify the command replies with the identifier.
993 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Added silc_server_get_client_route to resolve the route to
996 the client indicated by the client ID. Affected file is
999 * Added silc_server_relay_packet as general function to relay
1000 packet to arbitrary destination. This deprecates functions
1001 like _send_private_message_key, _relay_notify etc. Affected
1002 file is silcd/packet_send.[ch].
1004 Removed silc_server_send_key_agreement,
1005 silc_server_send_private_message_key and
1006 silc_server_packet_relay_notify functions from the file
1007 silcd/packet_send.[ch].
1011 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1012 server. Affected file silcd/packet_receive.[ch].
1014 * Implemented the KILL command to the client. Implemented the
1015 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1016 Affected files lib/silcclient/command[_reply].c and
1017 lib/silcclient/client_notify.c. Implemented the KILL notify
1018 printing in the user inteface.
1020 * Fixed a lot silc_parse_nick memory leaks from the client
1021 library in the file lib/silcclient/command.c.
1023 * Changed the silc_server_send_notify_on_channels's `sender'
1024 argument from SilcSocketConnection to SilcClientEntry to
1025 check the sender as entry and not as connection object and not
1026 to send to the client provided as argument. The affected file
1027 is silcd/packet_send.[ch].
1029 * The notify packets that are destined directly to the client used
1030 to not to be processed by the server. Now changed that and the
1031 server processes all notify packets. After relaying the packet
1032 to the client the notify packet is processed in the server.
1034 * The silc_server_free_client_data now checks whether there is
1035 pending outgoing traffic for the client and purges the data to
1036 the network before removing the client entry.
1038 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1040 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1041 an client is killed from the SILC Network. Updated the protocol
1044 Added new function silc_server_send_notify_killed to the
1045 silcd/packet_send.[ch].
1047 * Added function silc_server_packet_relay_notify to relay notify
1048 packets that are destined directly to a client. In this case
1049 the server does not process the notify packets but merely relays
1050 it to the client. Affected file silcd/packet_send.[ch].
1052 Added also silc_server_packet_process_relay_notify to check
1053 whereto relay the notify. Affected file is
1054 silcd/packet_receive.[ch].
1056 * Implemented the KILL command to the server.
1060 * Added the backup schema desgined last fall to the protocol
1061 specs for everyone to see. The specification is in the
1062 *-spec-xx.txt draft and the packet type definitions for the
1063 backup routers is in *-pp-xx.txt draft. Thusly, added also
1064 new packet type SILC_PACKET_CELL_ROUTERS.
1066 * A big security problem in the implementation discovered. The
1067 signoff of an client did not cause new channel key generation
1068 which it of course should've done. The channel keys must be
1069 always re-generated when client leaves (or signoffs) the channel.
1070 The silc_server_remove_from_channels funtion now handles
1071 the channel key re-generation.
1073 * Added `sender' argument to the silc_server_send_notify_on_channels
1074 to not to send the client provided as argument. Affected file
1075 silcd/packet_send.[ch].
1077 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * Implemented OPER and SILCOPER commands into the server and
1082 * Added silc_auth_verify and silc_auth_verify_data to verify
1083 the authentication directly from the authentication payload.
1084 It supports verifying both passphrase and public key based
1085 authentication. Affected file lib/silccore/silcauth.[ch].
1087 * Added `hash' field to the SilcIDListData structure. It is the
1088 hash negotiated in the SKE protocol. Affected file is
1091 * Slight redesigning of the SilcAuthPayload handling routines.
1092 Do not send SilcPKCS but SilcPublicKey as argument.
1094 * Implemented the public key authentication support to the
1095 serverconfig. The public key is loaded from the provided path
1096 and saved as authentication data to void * pointer. Thus,
1097 changed the unsigned char *auth_data to void *auth_data;
1099 * Fixed SHUTDOWN command to send the reply before the server
1100 is shutdown. :) Affected file silcd/command.c.
1102 * Fixed fatal bug in CONNECT command. The hostname was invalid
1103 memory and server crashed. Affected file silcd/command.c.
1105 * Fixed fatal bug in CLOSE command. The server_entry became
1106 invalid but was referenced later in the command. Affected file
1109 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1111 * Fixed fatal bug in failure packet handling. Server ignored
1112 the failure and thus crashed when it came.
1116 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1118 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1119 that the command may be executed only once in (about) 2 seconds.
1120 The old SILC_CF_LAG flag is same but allows command bursts up
1121 to five before limiting.
1123 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1124 server code. Various commands now includes the CF_LAG_STRICT
1125 flag to disallow any kind of miss-use of the command.
1127 * Fixed the silc_buffer_unformat to not to allocate any data
1128 if the length of the data is zero. It used to allocate the
1129 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1131 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1133 * Changed the format of AdminConnection configuration section
1134 in the server. Added username of the admin to the format.
1135 Affected files silcd/serverconfig.[ch].
1137 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1138 to return admin configuration data by host, username and/or
1141 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Implemented WHOWAS command to the server. Added the functions:
1145 silc_server_command_whowas_parse,
1146 silc_server_command_whowas_send_reply,
1147 silc_server_command_whowas_from_client and
1148 silc_server_command_whowas_from_server
1150 * Added <Client ID> argument to the WHOWAS command reply. Updated
1151 the protocol specs accordingly.
1153 * Implemented WHOWAS command and command_reply to the client
1156 Implemented the WHOWAS printing on the user interface.
1158 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1160 * Added new argument to the WHOWAS command reply, the real name.
1161 It is an optional argument. Updated the protocol specs.
1163 * Added SilcIDCacheDestructor callback that is registered when
1164 the SilcIDCache is allocated. The callback is called when
1165 an cache entry in the ID Cache expires, or is purged from the
1166 cache. Added into lib/silccore/idcache.[ch].
1168 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1169 to destruct the client entries when the cache entry expires.
1170 Other ID Cache's in server and in the client library ignores
1173 * If the ID Cache entry's `expire' field is zero then the entry
1174 never expires. Added boolean `expire' argument to the
1175 silc_idcache_add function in the lib/silccore/idcache.[ch].
1176 If it is TRUE the default expiry value is used.
1178 * Added silc_server_free_client_data_timeout that is registered
1179 when client disconnects. By default for 5 minutes we preserve
1180 the client entry for history - for WHOWAS command.
1182 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * Added support to the server to enforce that commands are not
1185 executed more than once in 2 seconds. If server receives
1186 commands from client more frequently, timeout is registered
1187 to process the commands. Affected file silcd/command.c.
1188 Added new function silc_server_command_process_timeout.
1190 * Changed NICK_NOTIFY handling in client library to check that
1191 if the client's nickname was changed, so there is no need to
1192 resolve anything from the server.
1194 * Removed error printing from the WHOIS and IDENTIFY commands.
1195 If error occurs then it is ignored silently in the client library.
1196 The application, however, may map the received error to
1197 human readable error string. The application currently maps
1198 the NO_SUCH_NICKNAME error to string.
1200 * Made the command status message public to the application. Moved
1201 them from lib/silcclient/command_reply.c to
1202 lib/silcclient/command_reply.h. The application can map the
1203 received command status to the string with the
1204 silc_client_command_status_message function.
1206 * Added check to the server to check that client's ID is same
1207 as the Source ID in the packet the client sent. They must
1210 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1212 * Added dist-bzip hook to the Makefile.am to make bzip2
1213 compressed distributions.
1215 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1217 * Server now enforces the maximum length for the nickname and
1218 the channel as protocol specification dictates. 128 bytes for
1219 nickname and 256 bytes for channel name.
1221 * Moved the WHOIS printing to the application. The client libary
1222 does not print out the WHOIS information anymore, the application
1223 must do it. Renamed silc_client_command_reply_whois_print to
1224 the silc_client_command_reply_whois_save.
1226 The client's idle time is also sent to the application now, and
1227 the idle is shown on screen.
1229 * Added silc_client_command_reply_identify_save to save the
1230 received IDENTIFY entries.
1232 * Do not check for channel private keys in message sending and
1233 reception if the channel does not have the PRIVKEY mode set.
1234 Affected file lib/silclient/client_channel.c.
1236 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1238 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1239 just surfaced after chaning the JOIN procedure.
1241 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1243 * Added silc_client_get_clients_by_list to get client entries
1244 from Client ID list, that is returned for example by JOIN
1245 and USERS command replies. The application should use this
1246 function for example when JOIN command reply is received to
1247 resolve the clients already on the channel (library does not
1248 do that anymore as USERS command reply is not used in the JOIN
1249 procedure anymore). Affected files lib/silcclient/silcapi.h and
1250 lib/silcclient/idlist.c.
1252 * JOIN command reply and USERS command reply returns now SilcBuffer
1253 pointers instead of unsigned char pointers when returning
1254 the client list and mode list.
1256 * Added <Client ID> argument to the JOIN command reply, mainly
1257 for the server to identify for which client the command was
1258 originally sent. Updated protocol specs accordingly.
1260 * Added SilcDlist private_key pointer to the SilcChannelEntry
1261 in the client to support the channel private keys. Affected
1262 file is lib/silcclient/idlist.h.
1264 * Added SilcChannelPrivateKey argument to the function
1265 silc_client_send_channel_message so that application can choose
1266 to use specific private ke if it wants to. If it is not provided,
1267 the normal channel key is used, unless private keys are set.
1268 In this case the first (key that was added first) is used
1269 as the encryption key.
1271 * Implemented the support for channel private key handling.
1272 Implemented the following functions:
1274 silc_client_add_channel_private_key,
1275 silc_client_del_channel_private_keys,
1276 silc_client_del_channel_private_key,
1277 silc_client_list_channel_private_keys and
1278 silc_client_free_channel_private_keys
1280 Affected file lib/silcclient/client_channel.c.
1282 * Added the support for the private keys in the channel message
1283 sending and encryption and in the message reception and
1284 decryption. Affected funtions are
1285 silc_client_send_channel_message and silc_client_channel_message.
1287 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Added SKE's key verify callback to the client library's
1290 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1292 * Removed the statement that server (or router) must send USERS
1293 command reply when joining to the channel so that the client
1294 knows who are on the channel. Instead, the client list and
1295 client's mode list is now sent in the JOIN command reply to the
1296 client who joined channel. This is better solution.
1298 * Added function silc_server_get_users_on_channel and function
1299 silc_server_save_users_on_channel to the silcd/server.[ch].
1301 * Removed function silc_server_command_send_users from the
1304 * Do not show topic on the client library anymore. The topic is
1305 sent in the command reply notify to the application and the
1306 application must show the topic now.
1308 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Added client searching by nickname hash into the IDENTIFY and
1311 WHOIS commands in the server as they were clearly missing from
1312 them. Affected file is silcd/command.c.
1314 * Fixed a bug in private message receiving in the client library.
1315 The remote ID was freed and it wasn't supposed, now it is
1318 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1320 * Minor fix to the channel payload; allocate the data area, as it
1321 needs to be of specific length.
1323 * If the key agreement port is zero then the operating
1324 system will define the bound port. Affected files are
1325 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1327 * Added new function silc_channel_payload_decrypt into the file
1328 lib/silccore/silcchannel.[ch].
1330 * Moved the channel message etc, check from silc_packet_decrypt
1331 to applications. The library calls now a generic
1332 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1333 when the packet is either normal or special. This was done to
1334 allow more wide range of checking that was not allowed when
1335 the code was in library. Now applications can do virtually any
1336 checks to the packet and return to the library the decision how
1337 the packet should be processed. Affected files are
1338 lib/silccore/silcpacket.[ch].
1340 Added silc_server_packet_decrypt_check to the server and
1341 silc_client_packet_decrypt_check to the client library.
1343 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1344 to send with specified source and destination information.
1346 * Channel message delivery between routers was broken after the
1347 channel key distribution was fixed earlier. The channel key
1348 was used be to distributed to other routers as well which is not
1349 allowed by the protocol. Now this is fixed and channel keys
1350 really are cell specific and the channel message delivery between
1351 routers comply with the protocol specification.
1353 * Fixed various commands in server to check also the global list
1354 for the channel entry and not just the local list. The affected
1355 file silcd/command.c.
1357 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1359 * Added assert()s to buffer formatting and unformatting routines
1360 to assert (if --enable-debug) when error occurs. Affected
1361 file: lib/silcutil/silcbuffmt.c.
1363 * Changed to auto-reconnect to check whether the remote host is
1364 router and register the re-connect timeout if it is. It used
1365 to check that whether we are normal server, but router must do
1366 auto-reconnect with another router as well. Affected file
1369 * Removed the [<key len>] option from CMODE command as the cipher
1370 name decides the key length, nowadays. See the defined ciphers
1371 from the protocol specification.
1373 * Added [<hmac>] option to the CMODE command to define the HMAC
1374 for the channel. Added SILC_CMODE_HMAC channel mode.
1376 * Added [<hmac>] option for the JOIN command so that user can
1377 select which HMAC is used to compute the MACs of the channel
1380 * Added Hmac field to the Channel Message Payload. The integrity
1381 of plaintext channel messages are now protected by computing
1382 MAC of the message and attaching the MAC to the payload. The
1383 MAC is encrypted. Now, it is clear that this causes some
1384 overhead to the size of the packet but rationale for this is that
1385 now the receiver can verify whether the channel message decrypted
1386 correctly and also when private keys are set for the channel the
1387 receiver can decrypt the packet with several keys and check from
1388 the MAC which key decrypted the message correctly.
1390 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1391 lib/silccrypt/silccipher.[ch].
1393 * Added silc_hash_len to return the digest length into the
1394 lib/silcrypt/silchash.[ch].
1396 * Rewrote parts of Silc Channel Payload interface in the
1397 lib/silccore/silcchannel.[ch]. The encode function now also
1398 encrypts the packet and parse function decrypts it.
1400 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Fixed a minor formatting bug in the SKE's key material processing.
1403 It actually might have processed the keys wrong way resulting
1406 * Redefined the mandatory HMAC algorithms and added new algorithms.
1407 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1408 and hmac-md5 truncated to 96 bits. The mandatory is now
1409 hmac-sha1-96. Rest are optional (including the one that used
1410 to be mandatory). Rationale for this is that the truncated HMAC
1411 length is sufficient from security point of view and can actually
1412 make the attack against the HMAC harder. Also, the truncated
1413 HMAC causes less overhead to the packets. See the RFC2104 for
1416 * Added new [hmac] configuration section. The SKE used to use
1417 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1418 is of course wrong. The official names that must be proposed in
1419 the SKE are the ones defined in the protocol specification
1420 (hmac-sha1-96 for example). The user can configure any hmac
1421 using any hash function configured in the [hash] section. At
1422 least, the mandatory must be configured.
1424 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1426 * Added HMAC list to the SKE proposal list. It has now both
1427 hash algorithm list and HMAC list. This makes the protocol
1428 incompatible with previous versions. The SKE now seems to work
1429 the way it is supposed to work, for the first time actually.
1431 * Defined plain Hash algorithms to the protocol specification.
1434 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1436 * Implemented support for key agreement packets into the server.
1437 Added functions silc_server_key_agreement and
1438 silc_server_send_key_agreement. Other than these functions,
1439 server has nothing to do with this packet.
1441 * Added support for private message key packets into the server.
1442 Added functions silc_server_private_message_key and
1443 silc_server_send_private_message_key.
1447 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1448 called in the protocol's final callback instead in the END
1449 protocol state. This makes a little more sense and in the same
1450 time in client we can use the same protocol routines for normal
1451 key exchange and to key agreement packet handling as well.
1453 * Added to both client's and server's KE protocol context the
1454 SilcSKEKeyMaterial pointer to save the key material. We will
1455 bring the key material to the protocol's final callback by doing
1456 this. The final callback must free the key material.
1458 * Added SKE's packet_send callback into client's KE protocol
1459 context so that the caller can choose what packet sending function
1460 is used. This way we can use different packet sending when
1461 doing normal SKE when doing key agreement packet handling (in
1462 the key agreement packet handling we do not want to encrypt
1465 * Implemented the responder side of the key agreement routines
1466 in the client. The client can now bind to specified port and
1467 accept incoming key negotiation. The key material is passed
1468 to the application after the protocol is over.
1470 * Implemented the processing of incoming Key Agreement packet
1471 in the client. Added function silc_client_key_agreement to
1474 * Implemented the intiator side of the key agreement routines
1475 in the client. The client can now initiate key agreement with
1476 another remote client. The key material is passed to the
1477 application after the protocol is over.
1479 * Created client_keyagr.c to include all the key agreement
1482 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1483 SILC_TASK_CALLBACK except that it is not static.
1485 * Created client_notify.c and moved the Notify packet handling
1486 from the client.[ch] into that file.
1488 * Created client_prvmsg.c and moved all private message and
1489 private message key routines from the client.[ch] into that file.
1491 * Create client_channel.c and moved all channel message and
1492 channel private key routines from the client.[ch] into that file.
1494 * Changed silc_client_get_client_by_id_resolve to resolve with
1495 WHOIS command instead of IDENTIFY command, in the file
1496 lib/silclient/idlist.c.
1498 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * Implemented the SKE's responder side to the Client library.
1502 * When FAILURE is received to the protocol do not trust it
1503 blindly. Register a timeout to wait whether the remote closes
1504 the connection as it should do it, only after that process the
1505 actual failure. This was changed to both client and server.
1507 * Added client_internal.h to include some of the structures
1508 there instead of client.h in lib/silcclient/.
1510 * Added function silc_task_unregister_by_callback to unregister
1511 timeouts by the callback function.
1513 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1515 * Some "Incomplete WHOIS info" errors has been appearing on the
1516 log files. Took away the entry->userinfo check from WHOIS
1517 reply sending. The entry->userinfo is now " " if client did not
1518 provide one. I thought this was fixed earlier but something
1519 is wrong still. Let's see if the error still appears.
1521 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1523 * Fixed a minor bug in the login when the channel key is
1524 re-generated in the server. It used to generate the key in
1525 wrong order and thus caused problems in the channel traffic.
1527 * Fixed a minor bug in channel key distsribution after
1528 KICK command. The key was not sent to the router even though
1531 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Added silc_ske_process_key_material_data as generic routine
1534 to process any key material as the SILC protocol dictates. The
1535 function is used by the actual SKE library but can be used by
1536 applications as well. This relates to the private message keys
1537 and the channel private keys since they must be processed the
1538 same way the normal SILC session keys. The protocol dictates
1539 this. Affected files: lib/silcske/silcske.[ch].
1541 Added also silc_ske_free_key_material to free the
1542 SilcSKEKeyMaterial structure.
1544 * Defined silc_cipher_set_key function to set the key for
1545 cipher without using the object's method function. The affected
1546 files: lib/silccrypt/silccipher.[ch].
1548 * Implemented silc silc_client_add_private_message_key,
1549 silc_client_add_private_message_key_ske,
1550 silc_client_del_private_message_key,
1551 silc_client_list_private_message_keys and
1552 silc_client_free_private_message_keys functions in the
1555 Added functions silc_client_send_private_message_key to send
1556 the Private Message Key payload and silc_client_private_message_key
1557 to handle incoming Private Message Key payload.
1559 * Added Cipher field to the Private Message Key payload to set
1560 the cipher to be used. If ignored, the default cipher defined
1561 in the SILC protocol (aes-256-cbc) is used.
1563 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1565 * Removed lib/silcclient/ops.h file.
1567 Redefined parts of the SILC Client Library API. Created new
1568 file silcapi.h that deprecates the ops.h file and defines the
1569 published Client Library API. Defined also private message key
1570 API and channel private key API into the file.
1572 This is the file that the application must include from the
1573 SILC Client Library. Other files need not be included by
1574 the application anymore.
1576 * Added new key_agreement client operation callback and also
1577 defined the Key Agreement library API for the application.
1579 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1581 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1582 is used by clients to request key negotiation between another
1583 client in the SILC network. If the negotiation is started it
1584 is performed using the SKE protocol. The result of the
1585 negotiation, the secret key material, can be used for example
1586 as private message key.
1588 Implemented the Key Agreement payload into the files
1589 lib/silccore/silauth.[ch].
1591 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Redefined ciphers for the SILC protocol. Added some new ciphers
1594 and defined the key lengths for the algorithms. Changed the
1595 code accordingly. The default key length is now 256 bits.
1597 * Fixed SKE key distribution function silc_ske_process_key_material
1598 when the key length is more than 128 bits. The default key
1599 length in SILC is now 256 bits.
1601 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1602 to indicate unsupported algorithm.
1604 * Renamed rijndael.c to aes.c and all functions as well.
1606 * Fixed a long standing channel key setting bug in client library.
1607 Weird that it has never surfaced before.
1609 * Fixed bug in channel deletion. If the entire channel is removed
1610 then it must also delete the references of the channel entry
1611 from the client's channel list as the client's channel entry and
1612 the channel's client entry share same memory.
1614 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1616 * Implemented CONNECT and SHUTDOWN commands in the client.
1618 * Implemented CLOSE command to the client.
1620 * Added the function silc_idlist_find_server_by_name into the
1621 files silcd/idlist.[ch].
1623 Added the function silc_idlist_find_server_by_conn into the
1624 files silcd/idlist.[ch].
1626 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1628 * DIE command was renamed to SHUTDOWN. Updated the both code
1631 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1632 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1634 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1637 * Added function silc_server_create_connection function to create
1638 connection to remote router. My server implementation actually
1639 does not allow router to connect to normal server (it expects
1640 that normal server always initiates the connection to the router)
1641 so the CONNECT command is only good for connecting to another
1644 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1646 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1647 or some other client was kicked from the channel.
1649 Implemented the handling of the notify type to both client
1652 Implemented silc_server_send_notify_kicked to send the KICKED
1653 notify. It is used to send it to the server's primary router.
1655 * Implemented the KICK command into server and client.
1657 * Added `query' argument to the silc_idlist_get_client function
1658 to indicate whether to query the client from server or not if
1661 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1662 to indicate that the client is not channel founder.
1666 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1668 * Removed the rng context from SilcPacketContext structure and
1669 changed that the packet routine uses the Global RNG API.
1671 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1673 * Added support for quit message that client can "leave" on the
1674 channel when it quits the SILC. It is ditributed inside the
1675 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1677 Added silc_server_free_client_data that will take the
1678 signoff message as argument.
1680 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1682 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1684 * Updated parts of the protocol specification to keep it up
1687 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1689 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1690 payloads in one packet.
1692 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1693 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1694 use now the new List flag.
1696 * Also deprecated the following packet types: REPLACE_ID,
1697 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1699 * Added list support for Notify packet in server.
1701 * Added silc_server_send_notify_channel_change to send the
1702 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1703 the silc_server_send_replace_id.
1705 * Added silc_server_send_notify_nick_change to send the
1706 NICK_CHANGE notify type. Deprecates the function
1707 silc_server_send_replace_id.
1709 * Added silc_server_send_notify_join to send the JOIN notify type.
1710 Deprecates the function silc_server_send_new_channel_user.
1712 * Added silc_server_send_notify_leave to send LEAVE notify type.
1713 Deprecates the function silc_server_send_remove_channel_user.
1715 * Added silc_server_send_notify_cmode and
1716 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1717 types. Deprecates the silc_server_send_set_mode function.
1719 * Added SERVER_SIGNOFF notify type to indicate that server has
1720 quit. This means that all clients on the channel from that
1721 server will drop. This can be also used when netsplit happens.
1723 Deprecated REMOVE_ID packet type since it is not needed anymore
1726 Added silc_server_send_notify_server_signoff to send the
1727 SERVER_SIGNOFF notify type. Deprecates the function
1728 silc_server_send_remove_id.
1730 Added also silc_server_send_notify_signoff to send the
1731 SIGNOFF notify type.
1733 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1734 SILC protocol from this day on. Changed the protocol
1735 specification as well.
1737 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1738 notify type. It is used between routers to notify about
1739 topic changes on a channel.
1741 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1744 * Partly updated the protocol specification to comply with the
1745 changes now made. It is still though a bit outdated.
1747 * The JOIN notify type now takes one extra argument <Channel ID>.
1748 The packet used to be destined to the channel but now the
1749 JOIN type may be sent as list thus it is impossible to
1750 destine it to any specific channel. By adding this argument
1751 it is again possible.
1753 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1755 * Added CREDITS file. The CHANGES and CREDITS file will appear
1756 in the distribution as well.
1758 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1760 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1761 types in the server's silcd/packet_receive.c.
1763 * Implemented CMODE and CUMODE to work in router environment.
1765 * Fixed minor encoding and decoding buglet from the
1766 lib/silccore/silcmode.c.
1768 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1771 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1773 * Changed all SilcConfigServer* and silc_config_server* to
1774 SilcServerConfig* and silc_server_config*, respectively.
1777 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1779 * Associated the ID (client or server ID) to the Authentication
1780 Payload to avoid any possibility of forging. Updated the
1781 protocol specification and the code accordingly.
1783 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1785 * The RSA key length is now save to the RsaKey context in the
1786 key generation process in lib/silccrypt/rsa.c. The key length
1787 is now used to figure out the maximum size of the block allowed
1788 to be encrypted/signed.
1790 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1791 is equivalent to the silc_mp_mp2bin but does not allocate any
1794 * Changed silc_mp_mp2bin API to take length argument. If it is
1795 non-zero then the buffer is allocated that large. If zero, then
1796 the size is approximated using silc_mp_sizeinbase, which however
1799 * Created Global RNG API which is global RNG that application can
1800 initialize. After initializing, any routine anywhere in the
1801 code (including library) can use RNG without allocating a new
1802 RNG object. This was done to allow this sort of use of the
1803 RNG in code that has no chance to allocate RNG object. All
1804 applications currently allocate this and many routines in the
1805 library use this. Affected file lib/silccrypt/silcrng.[ch].
1807 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1808 it to use the Global RNG API.
1810 * Defined Authentication Payload into protocol specification that
1811 is used during SILC session to authenticate entities. It is
1812 used for example by client to authenticate itself to the server
1813 to obtain server operator privileges.
1815 Implemented this payload into the lib/silccore/silcauth.[ch].
1816 Implemented also routines for public key based authentication
1817 as the new protocol specification dictates.
1819 Moved definitions of different authentication methods from
1820 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1822 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1823 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1824 silc_pkcs_verify_with_hash functions into the file
1825 lib/silccrypt/silcpkcs.[ch].
1827 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1829 * The client entry's userinfo pointer must be always valid.
1830 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1831 will fail since it requires the userinfo. Now, the userinfo
1832 is allocated as "" if actual userinfo does not exist. Actually,
1833 it must exist and it is totally Ok to drop client connections
1834 that does not announce the userinfo. However, we will make
1835 this workaround for now.
1837 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1838 to return the remote port by socket.
1840 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1842 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1843 SILC_SERVER_PENDING_EXEC and added an new macro
1844 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1845 data or when error occurs while processing the pending command.
1847 Added new argument `destructor' into silc_server_command_pending
1848 and to the SilcServerCommandPending object. This destructor is
1849 now called after calling the pending callback or if error occurs
1850 immediately. If error occurs the actual pending callback won't
1851 be called at all - only the destructor. The destructor may be
1852 NULL if destructor is not needed.
1854 All this applies for client library code as well. Similar
1855 changes were made there as well for the pending commands.
1857 In the client, the application must now allocate the
1858 SilcClientCommandContext with the silc_client_command_alloc
1861 * Added reference counter to the SilcServerCommandContext. Added
1862 function silc_server_command_alloc and silc_server_command_dup
1865 Same type of functions added to the client library for the same
1868 * Removed the cmd_ident from IDListData away since it is now
1869 global for all connections. It is the command identifier used
1870 in command sending and with pending commands. The affected file
1873 * Added reference counter to the SilcSocketConnection objecet to
1874 indicate the usage count of the object. The object won't be
1875 freed untill the reference counter hits zero. Currently only
1876 server uses this, and client ignores it. The client must be
1877 set to use this too later. The affected files are
1878 lib/silccore/silcsockconn.[ch]. Added also the function
1879 silc_socket_dup to increase the reference counter.
1881 This was mainly added because it is possible that the socket
1882 is removed underneath of pending command or other async
1883 operation. Now it won't be free'd and proper DISCONNECTING
1884 flags, etc. can be set to avoid sending data to connection that
1885 is not valid anymore.
1887 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1888 the connection. After that it sets SILC_SET_DISCONNECTED.
1889 It is, however, possible that the socket data is not still freed.
1890 The silc_server_packet_process now checks that data is not
1891 read or written to connection that is DISCONNECTED. The socket
1892 get's freed when the reference counter hits zero.
1894 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * Changed the client operation API: channel_message operation's
1897 `sender' is now the client entry of the sender, not the nickname
1898 and the `channel' is the channel entry, not the channel name.
1900 In the private_message operation the `sender' is now also the
1901 client entry of the sender not the nickname.
1903 Affected file is lib/silcclient/ops.h and all applications
1904 using the client operations.
1906 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1908 * Moved the calling of ops->connect() from connect_to_server_final
1909 into receive_new_id functin since that is the point when the
1910 client is actually allowed to send traffic to network. The
1911 affected file is lib/silcclient/client.c.
1913 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1915 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1916 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1917 (if needs broadcasting) instead of broadcasting the packets one
1918 by one which would make a burst in the network traffic.
1920 * Added `broadcast' argument to the functions in silcd/server.[ch]
1921 silc_server_create_new_channel[_with_id] to indicate whether
1922 to send New Channel packet to primary router.
1924 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1926 * Added new function into the silcd/server.[ch] files:
1927 silc_server_create_new_channel_with_id to create new channel with
1928 already existing Channel ID.
1930 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1931 lib/silccore/silcpacket.h. This packet is used t send list of
1932 Set Mode payloads inside one packet. Server uses this to set
1933 the modes for the channels and clients on those channels, that it
1934 announced to the router when it connected to it. The protocol
1935 specification has been updated accordingly.
1937 * The silc_server_new_channel did not handle the packet coming
1938 from normal server as it normally does not send that. However,
1939 when it announces its channels it does send it. Implemented
1940 the support for that.
1942 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1943 into the file lib/silccore/id.h.
1945 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1947 * Fixed memory leaks in the functions silc_idlist_del_client,
1948 silc_idlist_del_channel and silc_idlist_del_server in the file
1949 silcd/idlist.c. All of those leaked like a sieve.
1951 * Fixed some small memory leaks in the client's function
1952 silc_client_notify_by_server.
1954 * Added functions into silcd/server.c: silc_server_announce_clients,
1955 silc_server_announce_channels and silc_server_announce_server.
1956 These functions are used by normal and router server to announce
1957 to its primary router about clients, channels and servers (when
1958 router) that we own. This is done after we've connected to the
1961 These functions effectively implements the following packet types:
1962 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1963 and SILC_PACKET_NEW_ID_LIST.
1965 * Added new functions into the silcd/packet_receive.[ch]:
1966 silc_server_new_id_list, silc_server_new_channel_list and
1967 silc_server_new_channel_user_list to handle the incoming
1968 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1970 * Added support of changing Channel ID in the function
1971 silc_server_replace_id. If the server that announces a channel
1972 to the router already exists in the router (with same name but
1973 with different Channel ID), router is responsible to send
1974 Replace ID packet to the server and force the server to change
1975 the Channel ID to the one router has.
1977 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1978 client that the Channel ID has been changed by the router. The
1979 normal server sends this to the client. Client must start using
1980 the new Channel ID as the channel's ID.
1982 Implemented handling of this new type into lib/silcclient/client.c
1983 into the function silc_client_notify_by_server.
1985 * Added new function silc_idlist_replace_channel_id into the files
1986 silcd/idlist.[ch] to replace the Channel ID.
1988 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1990 * Call silc_server_command_identify_check always when processing
1991 the IDENTIFY command in silcd/command.c
1993 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1995 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1996 send keepalive packets. The packet can be sent by clients,
1997 servers and routers.
1999 Added function silc_socket_set_heartbeat into the file
2000 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2001 If not set, the heartbeat is not performed. The actual
2002 heartbeat is implemented in the low level socket connection
2003 library. However, application is responsible of actually
2006 Added silc_server_send_heartbeat to send the actual heartbeat
2007 packet into silcd/packet_send.[ch]. Server now performs
2008 keepalive with all connections.
2010 * Added silc_task_get_first function into lib/silcutil/silctask.c
2011 to return the timeout task with shortest timeout. There was a bug
2012 in task unregistration that caused problems. TODO has been
2013 updated to include that task system must be rewritten.
2015 * The client library will now resolve the client information when
2016 receiving JOIN notify from server for client that we know but
2017 have incomplete information.
2019 * Rewrote parts of silc_server_remove_from_channels and
2020 silc_server_remove_from_one_channel as they did not remove the
2021 channel in some circumstances even though they should've.
2023 * Encryption problem encountered in server:
2025 The LEAVE command used to send the Channel Key packet to the
2026 router immediately after generating it. However, the code
2027 had earlier sent Remove Channel user packet but not immediately,
2028 ie. it was put to queue. The order of packets in the router
2029 was that Channel Key packet was first and Remove Channel User
2030 packet was second, even though they were encrypted in the
2031 reverse order. For this reason, MAC check failed. Now, this
2032 is fixed by not sending the Channel Key packet immediately but
2033 putting it to queue. However, this is more fundamental problem:
2034 packets that are in queue should actually not be encrypted
2035 because packets that are sent immediately gets encrypted
2036 actually with wrong IV (and thus MAC check fails). So, packets
2037 that are in queue should be encrypted when they are sent to
2038 the wire and not when they put to the queue.
2040 However, the problem is that the current system has not been
2041 designed to work that way. Instead, the packet is encrypted
2042 as soon as possible and left to the queue. The queue is then
2043 just purged into wire. There won't be any fixes for this
2044 any time soon. So, the current semantic for packet sending
2047 o If you send packet to remote host and do not force the send
2048 (the packet will be in queue) then all subsequent packets to the
2049 same remote host must also be put to the queue. Only after the
2050 queue has been purged is it safe again to force the packet
2053 o If you send all packets immediately then it safe to send
2054 any of subsequent packets through the queue, however, after
2055 the first packet is put to queue then any subsequent packets
2056 must also be put to the queue.
2058 Follow these rules and everything works fine.
2060 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2062 * Added new function silc_server_remove_clients_by_server to
2063 remove all client entries from ID list when the server connection
2064 is lost. In this case it is also important to invalidate all
2065 client entires as they hold the invalid server entry. This
2066 fixes fatal bug when server has lost connection and will reconnect
2069 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2071 * Made some sanity checks to silc_server_daemonise like to check
2072 whether the requested user and group actually exists.
2074 * Added sanity check to SKE's silc_ske_responder_finish to check
2075 that the public and private key actually is valid.
2077 * Invalidate the client's nickname when receiving Replace ID
2078 packet and the Client ID is being replaced. This means that the
2079 server will query the nickname if someone needs it (client)
2082 * Sort the ID Cache in client library when the ID Cache data
2083 has changed (needs sorting).
2085 * Do not allow for SILC client to create several connections to
2086 several servers. The client does not support windows right now
2087 and generating multiple connections causes weird behaviour.
2089 Irssi-silc client does support windows and can handle several
2090 connections without problems, see: www.irssi.org and SILC plugin.
2092 * Fixed some places where client was added to the IDList. The
2093 rule of thumb is following (in order to get everything right):
2094 If the client is directly connected local client then the
2095 `connection' argument must be set and `router' argument must be
2096 NULL to silc_idlist_add_client function. If the client is not
2097 directly connected client then the `router' argument must
2098 bet set and the `connection' argument must be NULL to the
2099 silc_idlist_add_client function.
2101 * The funtion silc_server_packet_send_local_channel actually did
2102 not check whether the client was locally connected or not. It
2103 does that now. Fixed a bug related to LEAVE command.
2105 * Fixed Remove Channel User payload parsing bug in server's
2106 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2108 * The server's silc_server_save_channel_key now checks also the
2109 global ID list for the channel as it might not be in the local
2110 list. Fixed a bug related to LEAVE command.
2112 * Is this the end of the [<unknown>] buglet that has been lurking
2113 around for a long time? A little for loop fix in server's
2114 silc_server_command_whois_parse that is used by both IDENTIFY
2115 and WHOIS command. At least, this was a clear bug and a cause
2116 of one type of [<unknown>] buglet.
2118 * WHOIS and IDENTIFY commands call the function
2119 silc_server_command_[whois/identify]_check function even if
2120 we are not router server.
2122 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2124 * Added --with-gmp configuration option. If set the GMP
2125 is always compiled in the SILC source tree. If not set then
2126 it is checked whether the system has the GMP3 installed. If
2127 it has then the GMP won't be compiled (the system's headers
2128 and library is used), if it doesn't have it then the GMP is
2129 compiled in the SILC source tree.
2131 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2133 * Changed RSA private exponent generation to what PKCS #1
2134 suggests. We try to find the smallest possible d by doing
2135 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2136 not security fix but optimization.
2138 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2140 * Added new config entry [Identity] to fork the server and run
2141 it as specific user and group. A patch from Bostik.
2143 * Imported Dotconf configuration library into lib/dotconf.
2144 This will be used to create the SILC configuration files later.
2145 It will appear in the distsribution after this commit.
2147 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2149 * A big code auditing weekend happening. Auditing code for
2150 obvious mistakes, bugs and errors. Also, removing any code
2153 Removed files for being obsolete:
2155 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2156 inline in the file lib/silcutil/silcbuffer.h)
2158 o lib/silcutil/silcbufutil.c (the header has inline versions)
2160 Changed code to fix possible error conditions:
2162 o The buffer formatting routines now check that the destination
2163 buffer really has enough space to add the data. This applies for
2164 both buffer formatting and unformatting
2165 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2166 unformatting was changed to accomodate following rules:
2167 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2168 sent to the function while XXX_*STRING will not allocate or copy
2169 the data into the buffer. Instead it sets the pointer from the
2170 buffer into the pointer sent as argument (XXX_*STRING used to
2171 require that the pointer must be allocated already). This change
2172 makes this whole thing a bit more consistent and more optimized
2173 (note that the data returned in the unformatting with XXX_*STRING
2174 must not be freed now). The routines return now -1 on error.
2176 o Tried to find all code that use buffer_format and buffer_unformat
2177 and added return value checking to prevent formatting and
2178 especially unformatting errors and possible subsequent fatal
2181 o Changed ske->x and ske->KEY to mallocated pointers in
2182 lib/silcske/silcske.h. Fixed possible data and memory leak.
2184 o Added return value checking to all *_parse* functions. Fixed
2185 many memory leaks as well.
2187 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2188 so that buffer overflows would not happen. All code now also
2189 checks the return value as it can fail.
2191 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2193 * Added reconnection support to server if the normal server looses
2194 its connection to the router (for example if router is rebooted).
2195 The server performs normal reconnection strategy implemented
2196 to the server. Affected file silcd/server.c.
2198 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2200 * Added new packet type SILC_PACKET_SET_MODE that is used to
2201 distribute the information about changed modes (for clients,
2202 channels and clients channel modes) to all routers in the
2203 network. Updated the protocol specification accordingly.
2205 Added functions into silcd/packet_send.c and
2206 silcd/packet_receive.c: silc_server_send_set_mode,
2207 silc_server_set_mode.
2209 Added new files silcmode.[ch] into lib/silccore that implements
2210 the encoding and decoding of Set Mode Payload. Added new type
2211 SilcSetModePayload. Moved the definitions of different modes
2212 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2214 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2216 * Oops, a little mistake in server's connection authentication
2217 protocol. The protocol is not ended with FAILURE but with
2218 SUCCESS if the authentication is Ok. :) Affected file is
2221 * Implemented NICK_CHANGE notify handling in server in the file
2222 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2223 the local clients on the channel. After the changing nickname
2224 in router environment snhould work and the [<unknown>] nickname
2225 should appear no more.
2227 The silc_server_replace_id function that receives the Replace ID
2228 payload now sends the NICK_CHANGE notify type also in the file
2229 silcd/packet_receive.c
2231 * Changed WHOIS and IDENTIFY command to support the maximum amount
2232 of arguments defined in protocol specs (3328 arguments). This
2233 fixed a bug that caused problems when there were more than three
2236 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2238 * Added extra parameter, command identifier, to the
2239 silc_client_send_command so that explicit command identifier
2242 Changed that ID list routines uses specific command identifier
2243 when sending WHOIS/IDENTIFY requests to the server so that they
2244 can be identified when the reply comes back.
2246 Affected files lib/silcclient/command.[ch],
2247 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2249 * Added `sender' argument to silc_server_packet_send_to_channel
2250 to indicaet the sender who originally sent the packet to us
2251 that we are now re-sending. Ignored if NULL. Affected file
2252 silcd/packet_send.[ch].
2254 * Added some server statistics support in silcd/server_internal.h
2255 SilcServerStatistics structure and around the server code. Also
2256 send some nice statistics information when client is connecting
2259 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Fixed channel ID decoding in server's JOIN command reply in
2262 silcd/command_reply.c
2264 * Fixed braodcasting of replace ID payload to not to send it if
2265 we are standalone server in silcd/packet_receive.c.
2267 * Fixed all channel message sending routines to not to send
2268 packets to clients that has router set, since they are routed
2269 separately in the same function earlier. Affects file
2270 silcd/packet_send.c and all channel packet sending functions.
2272 * In USERS reply, res_argv[i] are not allocated, the table
2273 is allocated. Thus changed that free the table, not its
2276 * In server's whois_check and identify_check if the client is
2277 locally connected do not send any WHOIS commands - they are not
2280 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * Fixed some minor bugs in client when sending WHOIS command. The
2283 arguments was in wrong order.
2285 * Removed statis function add_to_channel from server in
2286 silcd/command.c that was previously used with the joining but
2289 * Tested USERS command in router environment successfully with two
2290 routers, two servers and two clients.
2292 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2294 * Reorganized the USERS command and command reply in client library
2295 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2296 When the command is given by user we register a pending command
2297 callback that will reprocess the command after the reply has been
2298 received from the server. When reprocessing the packet we then
2299 display the information. Thus, the USERS information is displayed
2300 now in the command callback instead of in the command reply
2301 callback. The processing of the command is same as previously
2302 when server has sent the command reply in the JOINing process.
2304 * Added to USERS command in silcd/command_reply.c to join the client,
2305 we didn't use to know about, to the channel after we've created
2306 a client entry for it. Also, for clienet we did know already still
2307 check whether it is on the channel or not and add it if not.
2309 * Removed silc_server_command_join_notify as the function and its
2312 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2314 * Changed the client's pending command handling to the same as the
2315 server's pending command handling. It is also now possible to
2316 execute command reply functions from other command reply
2317 function as the function callbacks for commands and command
2318 replies are one and same. The pending commands are not static
2319 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2320 in client connection context. Thus, pending commands are server
2321 connection specific as it is convenient.
2323 Changed the function silc_client_command_pending and
2324 silc_client_command_pending_del and added new function
2325 silc_client_command_pending_check. Removed the
2326 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2329 * Added cmd_ident, current command identifier, to the client
2330 connection context in lib/silcclient/client.h to keep track on
2331 command identifiers used in command sending. Client's command reply
2332 function handling now supports the mandatory command identifiers.
2334 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2335 funtions in client to fully support pending command callbacks.
2337 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2338 as one of the arguments to the application in the command reply
2341 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2342 before first releasing SILC but came back. Now it is removed again
2343 and should come back nomore. The FORWARDED flag was used only
2344 by the JOINing procedure by forwarding the command packet to router.
2345 Now, the JOINing procedure has been changed to more generic (due
2346 to various router environment issues) and FORWARDED is not needed
2347 anymore for anything. The protocol specification is yet to be
2350 Now, removed silc_server_packet_forward from server and the flag
2351 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2353 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2355 * Renamed NAMES command to USERS command. The NAMES was named that
2356 due to historical reasons. Now it is renamed. Also, rewrote
2357 parts of the USERS command. The nickname list is not sent anymore
2358 by the server. Only Client ID and mode lists are sent in the USERS
2359 command. Changed this also to the protocol specification.
2361 The client now resolves the names and stuff after it receives
2362 the USERS list from the server when joining to the channel.
2364 * WHOIS and IDENTIFY commands has been changed to support multiple
2365 Client ID's per command. One can now search for multiple users
2366 in the network by sending only one WHOIS or IDENTIFY command.
2367 Changed the code and the protocol specifications.
2369 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2370 uses silc_server_command_whois_parse to parse the request. */
2372 * If normal server, do not parse the WHOIS and IDENTIFY requests
2373 before sending it to the router. Saves some time.
2375 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2377 * Fixed JOIN command on client library. Wrong number of arguments
2378 used to crash the client.
2380 * Added silc_server_channel_has_global function to check whether
2381 channel has global users or not.
2383 * Added silc_server_channel_has_local function to check whether channel
2384 has locally connected clients on the channel.
2386 * The silc_server_remove_from_one_channel now checks whether the
2387 channel has global users or not after given client was removed from
2388 the channel. It also checks whether the channel has local clients
2389 on the channel anymore. If it does not have then the channel entry
2390 is removed as it is not needed anymore.
2392 * The silc_server_notify now checks on JOIN notify whether the joining
2393 client is one of locally connected or global. If it is global then
2394 the channel has now global users on the channel and that is marked
2395 to the channel entry. Also, it now saves the global client to
2396 global list who is joining and JOINs it to the channel. This is
2397 for normal server, that is.
2399 Changed silc_server_send_notify_on_channel,
2400 silc_server_packet_relay_to_channel and
2401 silc_server_packet_send_to_channel check if we are normal server
2402 and client has router set (ie. global client) do not send the
2403 message to that client, as it is already routed to our router.
2405 * Implemented LEAVE notify type handling in silc_server_notify
2408 * Tested LEAVE command in router environment successfully. Tested
2409 with two routers, two servers and two clients.
2413 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2415 * Implemented SIGNOFF notify type handling in silc_server_notify
2418 * silc_server_remove_id now removes the client entry from all channels
2419 it has joined and thusly sends SIGNOFF notify type.
2421 * Rewrote the NAMES list generation in server by removing two excess
2422 loops. The lists are created now inside one loop.
2424 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2426 * silc_server_remove_channel_user checks now also global list
2427 for channel and client.
2429 * silc_server_new_channel_user checks now both local and global
2430 list for channel and client. Fixed a bug in client id decoding.
2431 Used to decode wrong buffer.
2433 * silc_server_channel_message checks now both local and global
2434 list for channel entry.
2436 * Tested channel joining (hence JOIN) in router environment
2437 successfully. Tested with two routers, two servers and two
2440 * Tested channel message sending in router environment successfully.
2442 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2444 * Added silc_server_save_channel_key into server.[ch] to save the
2445 received channel key in Channel Key payload processing. It is
2446 also used in JOIN command reply handling.
2448 Equivalent function silc_client_save_channel_key added into
2449 client.[ch] into client library.
2451 * Changed JOIN command reply to send information whether the channel
2452 was created or not (is existing already) and the channel key
2453 payload. Changed protocol specs accordingly.
2455 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2456 the request was sent by ID and not by nickname. Crashed on
2459 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2461 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2462 now correctly save the received data.
2464 * silc_server_free_sock_user_data now notifies routers in the
2465 network about entities leaving the network.
2467 At the same time implemented functions silc_server_remove_id
2468 and silc_server_send_remove_id to receive and send REMOVE_ID
2469 packets. The packet is used to notify routers in the network
2470 about leaving entities. The ID removed will become invalid in
2473 * Added function silc_idlist_del_server into server. Removes and
2474 free's server entry from ID list.
2476 * silc_server_private_message function now checks, if we are router,
2477 that the destination ID really is valid ID, naturally.
2479 * In router when NEW_ID packet is received (for new client) the
2480 hash of the Client ID is saved in the ID Cache but the
2481 client->nickname is set to NULL, instead of putting the hash
2484 IDENTIFY command now also checks that client->nickname must be
2485 valid. If it is not if will request the data from the server who
2486 owns the client. Added new function
2487 silc_server_command_identify_check.
2489 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2490 to set the command to already allocated Command Payload.
2492 * Tested private message sending in router environment with two
2493 routers, two servers and two clients. Fixed minor bugs and now
2496 * Fixed segfault from client's NAMES command. Used to crash if
2499 * Forwarded packets must not be routed even if it is not destined
2500 to the receiver. Changed server code comply with this.
2502 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2504 * Added `require_reverse_mapping' boolean value to ServerParams
2505 structure. If TRUE (not default) the server will require that
2506 the connecting host has fully qualified domain name.
2508 If the reverse mapping is not required and hostname could not be
2509 found the IP address is used as hostname.
2511 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2513 * Implemented version string checking to both client and server.
2514 The check is incomplete currently due to the abnormal version
2515 strings used in development version of SILC.
2517 * Changed all command functions in server to use the new
2520 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2522 * Changed char *data to unsigned char *data in ID Cache system to
2523 support binary data as ID Cache data. Changed code to support
2524 binary data in lib/silccore/idcache.c.
2526 * Renamed silc_server_packet_relay_command_reply to
2527 silc_server_command_reply as it is normal packet receiving
2528 function. Rewrote the function to accept command replys for
2529 servers and not only for clients.
2531 * Mark remote router always as registered server if we are connecting
2532 to it. Otherwise, commands sent by the router to us are ignored.
2534 * All ID List find routines now returns the ID Cache Entry pointer
2535 as well if requested.
2537 * WHOIS command works now in router environment, tested with two
2538 routers, two servers and two clients.
2540 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2541 in router environment (as it is almost equivalent to WHOIS) but
2542 hasn't been tested thoroughly. Added new functions:
2544 silc_server_command_identify_parse
2545 silc_server_command_identify_send_reply
2546 silc_server_command_identify_from_client
2547 silc_server_command_identify_from_server
2549 * Disabled route cache adding because adding two different ID's with
2550 same IP replaces the old cache entry thus giving wrong route.
2551 The entry->router->connection is always the fastest route anyway
2552 so route cache may not be needed. Of course, new routes maybe
2553 established after receiving the ID when the entry->router->connection
2554 might not be anymore the most optimal.
2556 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * Add route cache for received ID for fast routing.
2560 * Added silc_server_packet_route to route received packet on router
2561 that is not destined to us.
2563 * Renamed silc_server_get_route to silc_server_route_get.
2565 * Added id_string and id_string_len fields into SilcServer to
2566 include encoded ServerID for fast comparing without excess
2567 encoding of the ID's.
2569 * Cleaned up WHOIS command on server side. Added following static
2572 silc_server_command_whois_parse
2573 silc_server_command_whois_check
2574 silc_server_command_whois_send_reply
2575 silc_server_command_whois_from_client
2576 silc_server_command_whois_from_server
2578 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2579 arguments in command replies. All command functions should be
2580 updated to use this macro.
2582 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2584 * Minor typo fixes on command reply handling on server.
2586 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2588 * Added silc_server_command_add_to_channel internal routine to add
2589 the client to the channel after router has created the channel and
2590 sent command reply to the server.
2592 * Added generic silc_server_send_command to send any command from
2595 * Use static buffer with ID rendering instead of duplicating data.
2597 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Fixed a channel user mode bug when joining to a channel server gave
2600 everybody channel founder rights, oops.
2602 * We mark ourselves as the router of the incoming server connection
2603 if we are router ourselves. This way we can check in some packet
2604 sending functions whether it is locally connected server. For
2605 incoming router connections we put NULL.
2607 * For router sending packets locally means now always sending the
2608 packet cell wide; to local clients and local servers. For normal
2609 server sending packet locally means sending it to only local
2612 * Fixed the JOIN command to really work in router environment. If the
2613 channel is created it is always created by the router. Router is
2614 also responsible of making the initial joining to the channel,
2615 sending JOIN notify to the sending server and distributing
2616 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2617 does not exist server doesn't do anything else but forward the
2618 command to the router which performs everything.
2620 * Added silc_server_send_channel_key function to send the Channel Key
2623 * Added silc_server_create_channel_key to create new channel key. The
2624 channel key is now re-generated everytime someone joins or leaves
2625 a channel, as protocol dictates. Note: channel->key_len is the
2628 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2630 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2631 packet_receive.[ch] to separate packet sending and receiving
2632 routines. The server.[ch] now includes everything else including
2633 actual packet processing (writing and reading data) and other
2636 Renamed silc_server_private_message_send_internal to
2637 silc_server_send_private_message. The routine is still though
2638 used only to relay private messages as server does not send
2639 private messages itself.
2641 Renamed silc_server_new_channel to silc_server_create_new_channel
2642 and added new function sicl_server_new_channel that handles the
2643 incoming New Channel packet. Added also new sending function
2644 silc_server_send_new_channel to send New Channel Payload.
2646 * Added new function silc_server_notify to process incoming notify
2647 packet to the server/router. Server may then relay the notify
2648 to clients if needed.
2650 * Added new function silc_server_new_channel_user to process incoming
2651 New Channel User packet. Router will redistribute the packet and
2652 send JOIN notify to its local clients and locally connected servers
2653 if needed. Normal server will send JOIN notify to its local client
2654 on same channel when received this packet. Added also corresponding
2655 sending function silc_server_send_new_channel_user to sent the
2658 * Added boolean route argument to send_notif_to_channel and
2659 packet_send_to_channel functions to attempt to route the packet
2660 if it is TRUE and send only locally if it is FALSE.
2662 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * silc_server_replace_id now broadcasts the received replace ID
2665 packet if it is not broadcast packet already. The router must
2666 broadcast to inform other routers about changed ID.
2668 * Added backpointer to server's router into SilcServer context in
2669 silcd/server_internal.h.
2671 * Fixed silc_server_packet_broadcast to send correct broadcast
2674 * The channel key is now distributed to the local client as soon
2675 as it is received from the router (in router environment) so that
2676 no other packet may be sent for the channel until client has
2679 * silc_server_remove_channel_user now broadcasts the received
2680 Remove Channel User packet if it is not broadcast packet already.
2681 The router must broadcast to inform other routers about removed
2684 * Added users field into SilcPacketContext that is a reference count
2685 of the context. One can increase the reference count by calling
2686 silc_packet_context_dup which is now changed to just increase the
2687 reference count instead of duplicating the data. The reference
2688 count is decresed by calling silc_packet_context_free that will
2689 free the data after the reference count hits zero.
2691 For now on the packet context and everything allocated into it
2692 (including the raw packet from network) must be freed by calling
2693 the new silc_packet_context_free function. Added also new function
2694 silc_packet_context_alloc that must be used now to allocate the
2695 context. This also means that if a routine is asynchronous from
2696 silc_[client/server]_packet_parse_type the packet context must
2697 be duplicated by calling silc_packet_context_dup. Otherwise it
2698 gets free'd after silc_[client/server]_packet_parse_type returns.
2699 Also, one must remember that if packet is duplicated then its
2700 reference count must be decresed by calling the free function as
2701 many times as it was duplicated.
2703 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2704 from both client and server.
2706 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2708 * Made joining to a channel working in router environment.
2710 * Cleaned up JOIN command on server side and create function
2711 silc_server_command_join_channel internal routine to make the
2714 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2716 * Changed silc_command_pending list to SilcDList. Also, added
2717 `ident' field to SilcServerCommandPending structure to identify
2718 the reply and to call correct callback.
2720 Added silc_server_command_pending_check function to replace the
2721 corresnponding macro. The silc_command_pending list is not
2724 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2725 to set identifier to previously allocated Command Payload. It
2726 is used to set identifier for command when resending Command
2729 * Added silc_command_payload_encode_payload to encode Command
2730 Payload buffer from SilcCommandPayload structure.
2732 * Added silc_argument_payload_encode_payload to encode Argument
2733 payload buffer from SilcArgumentPayload structure.
2735 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Changed WHOIS command to support router connection on server side.
2738 The whois request is always sent to router unless the server is
2739 standalone server. After server has received the reply from the
2740 router will it send the reply to the client.
2742 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2743 broadcast received broadcast packet. The function is used only
2744 by router. The broadcast packet is always sent to the router's
2747 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2748 render given ID to printable string, for log files for example.
2750 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2752 * Made basic router to router connections working. At least they
2753 can now connect to each other but nothing really works the way
2754 they are supposed - yet.
2756 * Added new initiator token to RouterConnection configuration
2757 file in silcd/serverconfig.[ch]. It is used to tell whether we
2758 are the initiator to the remote router or whether we'll expect
2759 the other end to connect.
2761 * Moved registering of listener task to silc_server_init, hence
2762 the server starts listenning as soon as it is run, even if it
2763 does not have connections to other routers. Let's see how well
2766 * Changed default connection retry timeouts for more suitable in
2769 * Removed cipher and such arguments from silc_idlist_add_client
2770 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2771 Added new function silc_idlist_add_data to add the keys and stuff
2774 * Added SilcIDListData structure and added it to SilcClientEntry
2775 and SilcServerEntry as their first field in the structure. This
2776 way we can explicitly cast the ID entries to the SilcIDListData
2777 structure and get common data for the entries. In past, we had
2778 to first check what type of connection it is and then cast it to
2779 correct ID entry type. Now, we can directly cast the opaque
2780 pointer to the SilcIDListData (no matter what ID entry it actually
2781 is) and get the data needed.
2783 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2785 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2786 in some circumstances even if threre were timeout tasks, though not
2787 IO tasks, but tasks anyway. Now fixed.
2789 * Defined SilcServerConnection structure to hold connection specific
2790 stuff about directly connected servers and routers. The definition
2791 is currently in silcd/server_internal.h. I thought about having
2792 a bit more important role fro this struct but for now it is used
2793 only when connecting to other server (or router actually).
2795 * Added connecting retry support in server when connecting to
2796 router(s). The retry feature implement exponential backoff
2797 algorithm. Also, added SilcServerParams structure to hold default
2798 parameters for server. For now, it include these retry settings
2799 and are hard coded. After server is moded to be as Silc Server
2800 Library this structure will be more important.
2802 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2804 * Changed client librarys channel->clients table to SilcList and
2805 changed code accordingly.
2807 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2809 * Changed client's channel table to SilcList and changed code
2810 accordingly. Also changed SilcChannelClientEntry to include back-
2811 pointer to the channel so that client entry can use that structure
2812 as list as well and we have fast cross-reference to the channel.
2813 This change dramatically decreased the complexity of channel
2814 handling with client entry and vice versa (removed one extra
2815 loop when searching for channel entry from many functions).
2817 * Changed server->sim from table to SilcDList and changed code
2820 * NAMES command can now be used from user interface. It will show
2821 the user list on the channel, neatly.
2823 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2824 Code now saves realname of the user if it becomes available.
2826 * Renamed configure.in to configure.in.pre and made ./prepare
2827 script to automatically add correct version string to
2828 configure.in which it creates from configure.in.pre.
2830 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2832 * NAMES command reply now shows users mode with the nickname when
2835 * Moved silc_client_ch[u]mode[_char] functions from
2836 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2837 place sucks, they are utility functions and should be in some
2840 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2842 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2845 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2849 * Added TRQ (efficient deque and list library) into lib/trq. This is
2850 a very good list library that is currently used in the SILC. Defined
2851 SilcList API over the library because I didn't like the API very
2852 much. See lib/trq/silclist.h for the API and examples of how to
2853 use the API. Fixed various places in the code to use the new
2854 SilcList API. The SilcList is meant for lists that has a structure
2855 already defined as a list. It is not suitable to add just some
2856 context to the list (in TRQ, the context is the list actually).
2858 So, I defined SilcDList that can be used for the purpose where
2859 predefined list structure does not exit. This can be used as
2860 such list. Now some context just can be added to the SilcDList.
2861 Currently this list is not used in the SILC just yet, though there
2862 are a lot places where this can replace dynamically allocated
2863 tables and I will fix these places, later, to use SilcDList.
2864 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2865 and use TRQ internally).
2867 Also fixed some annoying warning messages that the original TRQ
2868 code generated. Also minor changes to TRQ's Makefile.in.
2870 * Added support for querying by Client ID to both WHOIS and
2871 IDENTIFY commands into server, as required by the protocol.
2873 * Removed method function pointers from SilcBuffer structure. They
2874 weren't used to anything and just increased the context size for
2875 no good reason. This change also made silc_buffer_alloc and
2876 silc_buffer_free functions inline functions.
2878 * Disabled command flooding detection support until it's fixed so
2879 that it accepts commands in but does not execute them more than once
2882 * Added silc_net_localhost(), to return local hostname, into
2883 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2884 that must be initialized before calling silc_client_init.
2886 * Added new function: silc_server_send_notify_on_channels to send
2887 notify messages to all channels client has joined. It is assured
2888 that the message is sent only once per client.
2890 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2891 lib/silcutil/silcutil.[ch] as silc_format function. The new
2892 function is generic and is used by server as well, not only by
2893 the logging routines.
2895 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2896 the provided version string was not acceptable. Added new function:
2897 silc_ske_check_version into lib/silcske/silcske.h. The function
2898 must be implemented by the application (client or server) and it
2899 does not reside in the SKE library. The function checks the version
2900 string remote end sent.
2902 * Added back pointers (to opaque context and to SilcSocketConnection)
2903 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2905 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2906 duplicate packet context structure.
2908 * Changed `notify' client operation to send same arguments as client
2909 receives from server except for ID's. ID's are mapped to correct
2910 ID entry and that is returned. Also, if channel entry is not sent
2911 by server but the notify is for channel the channel entry is sent
2912 to application (otherwise application doesn't know that it is for
2913 channel (library gets it from packet's Destination ID)).
2915 * Added silc_client_remove_from_channels into client library to
2916 remove a client from all channels it has joined to. Used when
2917 received SIGNOFF notify from server. Added also new function
2918 silc_client_replace_from_channels to replace old ID entry with
2919 new ID entry on all channels. Used when received NICK_CHANGE
2922 * Fixed ID Cache list handling in silc_idlist_get_client in
2923 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2924 to get (or query) client by ID.
2926 * Updated TODO list.
2928 * Added connection authentication status message defined by the
2929 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2930 support for these into the code in client and server side.
2932 * Added generic function silc_client_send_command to send any command
2933 with variable argument list. Application should use this function
2934 to send commands if the command functions provided by the library
2935 does not suite for the application's user interface needs.
2937 * Added new `failure' client operation. Application is notified about
2938 received failure packet if client is executing a protocol. In this
2939 case the protocol's execution has failed.
2941 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2942 is required by the protocol.
2944 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2945 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2948 * Added status flag to SilcSKE object to indicate realtime status
2949 of the SKE protocol.
2951 * Application receives now exactly same command reply arguments as
2952 the library receives from server. However, if ID is received the
2953 corresponding ID entry is returned to the application (eg. Client
2954 ID is mapped to correct SilcClientEntry entry and that is returned).
2955 Changed command_reply client operation due to this change.
2957 * Changed all ID's in commands and in command replys as ID Payloads.
2958 Change affected both client and server side codes.
2960 All ID's sent in SILC network (with execption of ID's in SILC
2961 Packet header) are sent in ID Payload to support variable length
2964 * Server now notifies nick changes and notifies all clients on
2965 the channels about the new nickname (about the new Client ID,
2968 * Implemented CMODE command to change channel modes. Supports all
2969 channel modes defined by the protocol specs except ban and invite
2970 lists. (Also, private channel key mode is supported but support for
2971 setting private channel key in client is missing, thus, this mode
2972 has no effect on client side (except that server requires that the
2973 client uses private channel key and normal channel traffic does not
2976 Also, invite mode works per se, but INVITE command does not work
2977 yet correctly, so you can set channel as invite only channel but
2978 inviting clients to the channel does not work (it is yet to be
2979 thought what's the best way to do it).
2981 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2982 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2983 Implemented CUMODE command to change user's mode on the channel.
2984 Supports all modes defined by the protocol specs.
2986 * Added NAMES command reply to return users modes on the channel.
2988 * Removed unnecessary and slow ciphers from lib/silccrypt.
2990 * Set SO_KEEPALIVE option to connection sockets by default.
2992 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2994 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2995 redefined the Notify Payload into protocol specs.
2997 * Added silc_id_payload_parse_id to get ID directly from raw
3000 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3002 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3003 accept searching by Client ID as well.
3005 * Added support for LEAVE and SIGNOFF notify types in client library.
3007 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3008 to parse ID Payload from raw data.
3010 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Added flags parameter into silc_ske_assemble_security_properties
3013 function in lib/silcske/silcske.[ch].
3015 * Changed notify client operation to fit better for notify messages
3016 sent by server. The notify payload received from server is now
3017 passed to the application (after parsing it to SilcNotifyPayload).
3018 It is application's responsibility to retrieve the arguments
3019 from the payload and show the message the way it wants. The message
3020 sent by server is implementation specific.
3022 * Changed public keys to comply with the protocol specification.
3023 Old public keys are not supported anymore and are not compatible.
3025 * Removed nickname from Channel Payload as the latest draft removed
3026 it. The client must resolve the nickname from the NAMES command
3027 reply received when it joined the channel.
3029 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3031 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * Fixed some errors in protocol specification drafts.
3035 * Created lib/silccore/silcnotify.c to implement Notify Payload
3036 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3037 generic payloads described by protocol specifications. The file
3038 includes implementations for ID Payload and Argument Payload.
3040 * Changed Command Payload implementation to use the new Argument
3041 Payload. Changed command_xxxx_payload to command_payload_xxxx
3042 to comply with SILC coding conventions.
3044 * Added suppport for Argument Payload handling in Notify Payload
3045 implementation as protocol requires it. Added the new support
3046 into server and client lib as well.
3048 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Added support for multiple nicknames on same channel. [n] is
3051 added locally to the nickname if there are more than one same
3052 nicknames on the channel.
3054 * Server now sends all nicknames that matched WHOIS request.
3055 Client also shows the list received from server.
3057 * Added TOPIC command to client side. User can now set and show
3058 current topic on channel.
3060 * Added MOTD command to client and server. Also, server sends the
3061 motd when client connects to the server.
3063 * Changed version strings to comply ISO 8601.
3065 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * Fixed protocol error handling in client library. It should now
3068 cope even if the SKE fails for some reason.
3070 * Made new protocol specification drafts for submitting to IETF.
3072 * Implemented TOPIC command to server in silcd/command.c.
3074 * Added two new notify types into lib/silccore/silcnotify.h:
3075 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3076 notify nickname change and topic setting/change on a channel.
3078 * API change of command_reply operation in client library. The
3079 application gets now the status type received from server as well.
3081 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3085 * Cras fixed and optimized the packet handling even further and
3086 it should work now. Minor change to the prototype of function
3087 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3089 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Added new function into lib/silcutil/silcschedule.[ch]:
3092 silc_schedule_with_fd to select() a specified fd. The function
3093 returns after timeout expires or data arrives or goes. The
3094 function is used by packet routines to wait that all data is
3095 received from network.
3097 * Fixed data reading from network in lib/silccore/silcpacket.c.
3098 The code now assures that all data is read from the fd and then
3099 continues packet processing. This was a bug fix since the code
3100 used to drop some data in some circumstances.
3102 * Added new function into lib/silcclient/client.[ch]:
3103 silc_client_start_key_exchange to start key exchange after
3104 connection has been established to server. The code internally
3105 now uses this funtion but its main purpose was to provide it
3106 for applications that perform their own connecting. After
3107 application has created a connection it merely calls this
3108 function to start the key exchange between client and server.
3109 The library takes care of everything else after that.
3111 Updated also lib/silcclient/README to explain the usage of
3114 * Do not send to application information that connection has
3115 been established. Application gets notified it by connect
3118 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Applied cras's patch to add silc_schedule_one function. The
3121 function runs scheduler once and returns.
3123 * Fixed the scheduler after cras messed it up. The timeout
3124 handling works now as it's supposed to work.
3126 * Added into lib/silccore/ silcnotify.h to include notify
3127 message types support. Changed silc_server_send_notify*
3128 functions, in server.[ch], to support those new notify types.
3129 Added the support for the notify types into client library,
3130 as well. Added new notify client operation into ops.h in
3133 * Changed silc_server_packet_send_to_channel to send normal
3134 packets instead of just channel message packets. The function
3135 is now used to send the notify packets to channels. It is not
3136 used to send channel message packets anymore, as server never
3139 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3140 va_arg()s as it seems to require it nowadays. I guess, if SILC
3141 is compiled with older va_arg() the new code should work anyway.
3143 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Splitted core library. Core library (lib/silccore) includes
3146 now only SILC protocol specific core (and common) components.
3147 Created new utility library (lib/silcutil) that includes more
3148 generic purpose stuff. The stuff for util library was taken
3149 from the old core library. This was minor and easy split.
3151 * Created SILC Client Library (lib/silcclient) that includes
3152 implementation of the SILC client without user interface. This
3153 was major move from silc/ directory. The code has been changed
3154 so that it is transparent towards the user interface. The
3155 silc/ directory includes now the same user interface as before
3156 and it uses the new client library. Read lib/silcclient/README.
3157 Basicly, the client library performs everything else related
3158 to SILC except user interface handling. Also, configuration
3159 files are considered to be part of user interface and library
3160 does not handle them.
3162 This change also changed a lot of structures, function naming etc.
3163 Most important change was that SilcClientWindow object was
3164 renamed to SilcClientConnection in the client library. Created
3165 also new file lib/silcclient/ops.h. Also added new files
3166 silc/local_command.[ch] and silc/client_ops.[ch].
3168 All these changes were made to make it easier for user interface
3169 designers to create what ever user interface for the SILC client
3172 It is also expected that the server will be moved to lib
3173 directory as well and SILC Server Library will be created;
3174 sometimes in the future.
3176 * Removed Local commands from lib/silccore/silccommand.h as
3177 they are application specific and new client library does not
3178 handle any of those anymore.
3180 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3181 old client implementation in silc/.
3183 * Added support for callback functions in SILC_LOG_* macros.
3184 Application can now set its own callbacks that will be called
3185 instead of using the default functions that will always print
3186 the debug messages to stderr (or stdout). Also, debugging can
3187 now be disabled by setting silc_debug to FALSE and re-enabled by
3188 setting it to TRUE. Note, that logging will still work even
3189 if debugging is disabled.
3191 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3192 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3193 silc_log_reset_debug_callbacks.
3195 * To enable debugging in silc client one must give now -d
3196 option on command line.
3198 * Changed silc_schedule_init to automatically allocate task queues
3199 if they are not allocated before calling it.
3201 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3203 * Added GMP 3.1 into math library.
3205 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3207 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3208 a channel in SILC network. The packet is used by servers and
3209 routers to notify other routers that user has left a channel.
3210 This little feature was missing until now. Added the feature
3211 to protocol specification as well.
3213 Added functions: silc_server_send_remove_channel_user and
3214 silc_server_remove_channel_user into server.[ch].
3216 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3217 lib/silccore/silcpacket.h. However, they are not implemented
3220 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3222 * Fixed joining to a channel and sending channel messages
3223 between server and router. The channel message sending should
3224 now work inside a cell.
3226 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Fixed the private message sending between server and router.
3229 The private message sending should now work inside a cell.
3231 * Added silc_server_replace_id into server.[ch] to replace
3232 existing ID in the SILC network.
3234 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3235 and silc_idlist_replace_server_id into idlist.[ch] in server.
3237 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Fixed the server to server connections. Server can again now
3240 connect to router. Router to router connections probably does
3243 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3245 * Added dynamic protocol registering support. Now protocols can
3246 registered and unregistered on the fly. Patch by cras.
3248 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3250 * Added lib/contrib directory to hold routines that some platforms
3251 don't have but are needed by SILC.
3253 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3254 into lin/contrib to provide getopt() and getopt_long() for
3255 those who don't have it.
3257 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Added AWAY command to client. When away message is set and
3260 client receives a private message packet the client automatically
3261 replies to the sender with the away message.
3263 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3264 bug seemed to be the cause of recent problems when compiling
3267 * Added version detection support to SKE protocol specification
3268 and added the new changes to the SKE implementation as well.
3269 There were other minor changes in the SKE protocol as well.
3271 Many changes in lib/silcske/silcske.[ch] and in
3272 lib/silcske/payload.[ch].
3274 * Added ^U functionality, clear input line. Patch from cras.
3276 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3278 * Mainly small bugfixes on core library. Fixed some debugging
3279 logging and buffer overflow in silclog.c.
3281 * Updated config.sub and config.guess on the distribution tree.
3283 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Added command lagging support in server. Client may execute
3286 commands now only once in two seconds.
3288 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3290 * Optimized packet reception. MAC computation and checking is now
3291 also more optimized. A lot previously duplicated code is now
3292 used as generic by both client and server.
3294 * Fixed key pair generation in clientutil.c
3296 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Added into lib/silccore/silcbufutil.[ch] new function;
3299 silc_buffer_realloc.
3301 * Moved generic packet sending/encryption functions to
3302 lib/silccore/silcpacket.[ch] from client and server. Some
3303 rewriting of the functions.
3305 * Moved all generic packet reception/decryption functions to
3306 lib/silccore/silcpacket.[ch] from client and server. The
3307 packet processing is now much cleaner in both client and server.
3308 These were major changes in both client and server.
3310 * Created many common functions in server to do packet sending.
3311 Previously code were duplicated a lot, this has been removed
3314 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3316 * Rewrote major parts of the ID cache system. Don't know
3317 whether it is better now or not but at least the API is more
3320 * Major rewrite on ID cache stuff on client because of the ID
3321 cache API changes. Added idlist.c to client.
3323 * Also major rewrite on ID cache stuff on server as well.
3324 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3325 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3326 in hand, instead they are all put into the ID cache system now.
3327 All server_idlist_* routines uses ID cache now instead of
3328 traversing its own lists (those lists does not exist anymore).
3329 SilcIDList though still exists. Also, SilcXXXEntry's are
3332 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3334 * Finally made the SKE implementation compliant to the protocol
3335 specification. All mp integers are now binary encoded as
3336 opposed being HEX encoded.
3338 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3341 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3342 functions: silc_[encode/decode]_pem. Also added function
3343 silc_encode_pem_file to PEM encode with newlines ('\n') for
3346 * SILC public keys are now encoded either PEM or binary. Same
3347 option is for private keys as well. By default private keys
3348 are binary encoded and public keys PEM encoded. Silly HEX
3349 encoding were removed.
3351 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3352 function to create fingerprints.
3354 * Fixed a bug in SHA1; does not change the original data anymore.
3356 * Partly implemented INFO command on client and server side.
3357 Fixed CLEAR command. Changes to SERVER command; show current
3358 server(s) when giving command without arguments. Added
3359 VERSION command to client.
3361 * Added check to server that unregistered connections cannot
3362 execute commands (unless it is specificly allowed).
3364 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3366 * Fixed screen refresh.
3368 * Fixed channel joining bug from client. On some circumstances
3369 client tried to join to a channel it had already joined.
3371 * Added public key verification process into client's protocol.c.
3372 The client now verifies the public key from user and saves
3373 it into ~./silc/serverkeys/ directory.
3375 Added into: clientutil.[ch]: silc_client_verify_server_key.
3377 * Changed SKE protocol's silc_ske_initiator_finish function
3378 to accept callback function that verifies the received public
3379 key. Removed old silc_ske_verify_public_key function.
3381 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3384 silc_pkcs_private_key[_data]_set.
3386 * Made the password and public authentication more cleaner in
3387 server's protocol.c.
3389 * Removed historic and obsolete protocol `channel_auth' from
3390 both client and server.
3392 * Removed wrong way of sending command status messages from
3393 server to client in server's command.c. The old way violated
3394 protocol specification.
3396 Changes to silccore/silccommand.[ch]: removed
3397 silc_command_encode_status_payload -> not needed anymore,
3398 changed silc_command_encode_payload_va to accept extra
3399 argument on variable argument list. The argument type must
3400 now be provided to the function. Also, added new function:
3401 silc_command_encode_reply_payload_va which is same as
3402 normal command_encode_payload_va except command status type
3403 is provided as extra argument.
3405 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Added ~./silc directory handling. The directory includes the
3408 public and private keys for the client.
3410 Added silc_client_check_silc_dir, silc_client_create_identifier
3411 and silc_client_load_keys.
3413 * Implemented SILC protocol compliant public key. Added public
3414 and private key saving to and loading from files.
3416 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3417 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3418 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3419 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3420 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3422 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3423 silc_pkcs_load_[public/private]_key.
3425 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Added silc_server_get_route (route.[ch]) to get connection
3428 data for the fastest route for given ID.
3430 * Implemented INVITE command on client and server. The command
3431 were re-defined in the SILC Protocol Specification and the
3432 implementation now complies with the specification.
3434 * Implemented PING command on client and server.
3436 * Implemented NAMES command on client and server. The server side
3437 supports currently only normal server not router server yet.
3438 Some changes to NAMES definition in SILC protocol specification.
3440 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Implemented LEAVE command on client and server.
3444 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3445 again. This change was made to the protocol as well. Server
3446 should not violate the protocol specification anymore.
3448 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3450 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3451 was tested. SOCKS4 was not but should work anyway.
