1 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Check minor version as well in the SKE. Affected files are
4 silcd/protocol.c and lib/silcclient/protocol.c.
6 * Added --identifier option to the server so that an identifier
7 can be when creating the public key for the server. Affected
10 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
11 lib/silccrypt/silcpkcs.c.
13 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
15 * Register default ciphers and stuff when using -C option with
16 the server. Affected file sildc/silcd.c.
18 * Put back the servers public key filename format, it is better
19 than the new one. For now, the client keys are saved with the
20 new filename format. The affected file silc/client_ops.c.
22 * Implemented the Cipher API for the rest of the ciphers that
23 did not implement it or implemented it the wrong way.
25 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
27 * Register default ciphers and stuff when using the -S option
28 in the client. Affected file silc/silc.c. Same also when
29 creating new key pair with -C option.
31 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
33 * Fixed the silc_verify_public_key client operation function to
34 save the public keys differently. The fingerprint is now
35 used as filename and not the hostname. This way also the
36 client keys are saved uniquely and not with hostnames. The
37 affected file is silc/client_ops.c.
39 * Trimmed the silc_hash_fingerprint function to remove extra
40 whitespaces from the end of the fingerprint. The affected
41 file is lib/silccrypt/silchash.c.
45 * Added silc_cipher_register_default function to register all
46 default ciphers. It can be used when configuration files
47 does not exist and the application does not want any specific
48 ciphers in any specific order.
50 The SilcDList is now used as silc_cipher_list dynamically
51 allocated cipher list. Removed the static list all together
52 and now all ciphers must be allocated to the dynamic list.
53 The silc_cipher_alloc routine was changed to check only the
56 All silc_cipher_* routines that used to return int returns
59 The affected files lib/silccrypt/silccrypt.[ch].
61 * The same thing was done to silc_hash_* as for silc_cipher_*
62 routines. Affected files lib/silccrypt/silchash.[ch].
64 * The same thing was done to silc_pkcs_* as for silc_cipher_*
65 routines. Affected files lib/silccrypt/silcpkcs.[ch].
66 Added also silc_pkcs_[un]register[_default] functions.
67 Removed the data_context from the PKCS API.
69 * Added silc_hmac_register_default function to register default
70 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
71 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
72 to unregister all hmacs at once.
74 * Register the default ciphers, hash functions, PKCSs and HMACs
75 if client's configuration file does not exist. The affected
78 * The client did not load the hash functions from the SIM
79 modules at all. Added support for this. Affected file is
82 * When decoding public key with silc_pkcs_public_key_decode, check
83 the supported algorithm only if PKCS are registered. Affected
84 file lib/silccrypt/silcpkcs.c. The same was done with the
85 silc_pkcs_private_key_decode.
87 * Fixed the SILC List routines to keep the list always in order.
88 It used to change the list's order when traversing the list but
89 not it preserves the order. Affected file lib/trq/silclist.h.
91 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
93 * Added the client library to use the SilcSocketConnection's
94 reference counter (by silc_socket_dup) to prevent the bug that
95 the socket object may be freed underneath async operation.
97 * The name resolv library checking fixes in the configure.in.pre.
100 * Created new version of the protocol drafts for future
101 development. The -03 drafts are the ones that will be changed
102 in the trunk now and the -02 will remain as they are.
104 * Send list of CUMODE notifys to the router when announcing
105 the channel users to the router. Affected file silcd/server.c.
106 If the router receiving channel founder CUMODE for a channel
107 that already has channel founder it will send CUMODE notify
108 to the sender to remove the channel founder rights from the
109 announced client. Affected file silcd/packet_receive.c.
111 * The CUMODE notify may now use Server ID as well as the entity
112 who changes the mode. Updated protocool specs.
114 * Updated INSTALL and README files.
116 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
118 * New web pages in the http://silc.pspt.fi. The pages was
123 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
125 * Implemented the [DenyConnectin] config section in the server.
126 Added silc_server_config_denied_conn to check whether incoming
127 connection is denied. Affected file silcd/serverconfig.[ch].
129 * Do not check the ports when checking the incoming configuration
130 data if the port is 0, meaning any. Affected file is
131 silcd/serverconfig.c.
133 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
135 * Fixed buffer overflow in silc_string_compare in the file
136 lib/silcutil/silcutil.c.
138 * Fixed double free in silc_server_command_leave in the file
141 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
143 * Fixed the version checking in the server. Affected file is
146 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Fixed the configuration data fetching when accepting new
149 connections in the server. Affected file silcd/server.c.
151 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
153 * Added `sender_entry' argument to the function
154 silc_server_packet_relay_to_channel so that we can check
155 whether some destination actually belongs to the same route
156 the sender belongs (ie, we must not resend the packet to the
157 sender). Affected file silcd/packet_send.[ch].
159 * Added `servername' field to the SilcClientEntry in the server
160 to hold the name of the server where client is from. Affected
161 file is silcd/idlist.h.
163 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
165 * Moved the channel message encrypting in the router betwen
166 router connections from silc_server_channel_message to the
167 silc_server_packet_relay_to_channel since we want to check
168 whether we have anybody channel before encrypting anything.
169 Affected files silcd/packet_[receive/send].c.
171 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
173 * Fixed the [AdminConnection] server config section to support
174 multiple entries. Affected file silcd/serverconfig.c.
176 * Added support into the server to check the validity of the
177 incoming connection before executing any KE or authentication
180 * The connection configuration is now saved to the KE and
181 connection auth protocol contexts and not fetched anymore in
182 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
184 * The local hosts listenning address and port is also resolved
185 now when starting the server. We want to have the socket object
186 to include the real address and port for the listener. Added
187 new function silc_net_check_local_by_sock into the files
188 lib/silcutil/silcnet.[ch].
190 * Fixed a broadcast bug in server -> do not broadcast if we
193 * Fixed a routing bug. Do not route broadcast packets ever.
194 Broadcast packets must be processed always and not routed since
195 they may be destined to some other host than yourself and thus
196 would get routed without no good reason. Affected file is
199 * Added function silc_server_config_is_primary_route to check
200 whether primary router connection has been configured (a router
201 configuration that we are initiating). If there is not, we
202 will assume that there is only two routers in the SILC network
203 and we will use the incoming router connection as our primary
204 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
206 * Changed the order of the broadcasting. Broadcast _after_ the
207 packet has been processed not before. Affected file is
210 * Fixed a [ClientConnection] parsing bug. The port was never
211 parsed correctly thus resulting to port 0. Affected file
212 silcd/serverconfig.c.
214 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
215 argument and did not set the broadcast packet flag. Affected
216 file silcd/packet_send.c. Fixed same bug in the function
217 silc_server_send_notify as well.
219 * If we receive NEW_ID packet for our own ID in the server, ignore
222 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
226 * Removed the nickname from the Private Message Payload.
227 Updated the code and the protocol specs.
229 * Updated protocol specs for submitting to the IETF.
231 * Tweaked the Random Number Generator a bit. Affected file
232 lib/silccrypt/silcrng.c. Exported a new function
233 silc_rng_[global]_add_noise which can be used to add more
236 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
238 * Do not parse packets with different timeout when protocol
239 is active -> may cause problem with rekey. Affected file
242 * When server receives signoff notify it must not create
243 new channel key if the client is on any channels since the
244 sender of the signoff notify will create it.
246 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
248 * Added printing of error messages during SKE protocol from the
249 failure packet sent by server during SKE. Affected file
252 * Removed the client's failure_callback handling with timeout
253 and handle it immediately when received.
255 * The SKE library returned wrong type in SUCCESS and FAILURE
256 packets. They must be 32 bit MSB not 16 bit MSB.
258 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
260 * Ok, rewrote the logic of the re-key and now it seems to work.
261 I tested it on high traffic with frequent re-keys without
262 problems. Added hmac_receive (and renamed hmac to hmac_send)
263 in SilcClientConnection in lib/silcclient/client.h and
264 in SilcIDListData in silcd/idlist.h. Also, removed the
265 SilcPacketParserContext's cipher and hmac fields as they are
266 not needed anymore and actually caused some problems when
267 the ciphers and hmac's changed underneath the packet parser.
269 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
271 * If re-key protocol is active then process the incoming packets
272 synchronously since we must assure that icoming packets encrypted
273 with the old key is processed before the new keys is set to
274 use. This is true other packets than for REKEY packets.
275 Affected file silcd/server.c. The same was done to client library
276 as well, affected file lib/silcclient/client.c.
278 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
280 * Fixed bug in client and server to accept the force send if
281 the packet is send from silc_[server/client]_packet_process
282 function. Otherwise the packets are never delivered, oops.
284 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
286 * Disable force sending of packets when REKEY protocol is active.
287 We must assure that no packet is sent directly when rekey is
288 performed. All packets must be sent through packet queue.
289 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
290 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
291 function is silc_[server/client]_packet_send_real to check
294 * Replaced the SIM paths from example config files to
295 /usr/local/modules. Also, make install creates now
296 /usr/local/silc/logs directory to hold all the SILC server
299 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
301 * Made the configure.in.pre work on Solaris. Patch by salo.
303 * Made all ciphers compatible with non-x86 machines. Defined
304 CBC mode macros into lib/silccrypt/ciphers_def.h.
306 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
308 * Fixed the make install.
310 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
312 * When MAC computation fails the silc_packet_decrypt returned 0
313 even though it was supposed to return -1. Fixed this. The
314 affected file is lib/silccore/silcpacket.c.
316 * Do not replace the config files in /etc/silc (in make install)
317 if they already exist. Affected file ./Makefile.am.
319 * Do not send re-key packets immediately but through packet queue.
320 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
322 * Changed silc_net_check_host_by_sock to return FALSE if the
323 IP/DNS could not be resolved. Though, it returns the IP address
324 now even if it could not resolve it (but returns also FALSE).
325 Affected file lib/silcutil/silcnet.[ch].
327 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
329 * Added silc_pkcs_decode_identifier to decode the public key's
330 identifier. Affected file lib/silccrypt/silpkcs.[ch].
331 Added also silc_pkcs_free_identifier. Added also new context
332 SilcPublicKeyIdentifier.
334 * Added -S option to the silc client. It is used to dump the
335 contents of the specified public key file.
337 * Changed the PKCS api to return the public key length when
338 setting the public key.
340 * Fixed a fatal bug in the public and private key file loading.
341 Affected file lib/silccrypt/silcpkcs.c.
343 * Execute the packet parsing for client with zero (0) timeout
344 if the protocol is active. Affected file silcd/server.c.
346 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * Made the key generation options to the silcd program. Added
349 -C option, equivalent to client's option.
351 * Added new [ServerKeys] config section to the server. It
352 configures the server's public and private key.
354 * Defined generic Public Key Payload into the protocol
355 specification to send specific type of public keys and
358 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
359 public key or certificate.
361 * Implemented the GETKEY command to the server and to the
362 client library and on user interface.
364 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
366 * Made preliminary `make install' work.
368 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
370 * Added SilcServerRekey context into silcd/idlist.h.
372 * Added the PFS support as defined in the specification to the
373 SKE protocol. Affected files lib/silcske/*.c.
375 * Added `ske_group' field to the SilcServerRekey context to hold
376 the number of the SKE group that is used with PFS in re-key.
377 Affected file silcd/idlist.h.
379 * Added PFS re-key support to the server. Affected file is
382 * Added silc_protocol_cancel to cancel execution of the next
383 state of the protocol. Affected file is
384 lib/silccore/silcprotocol.[ch].
386 * Added the re-key support with and without PFS to the client
387 library. Re-key is performed once in an hour, by default.
389 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
390 Added silc_client_rekey_callback and silc_client_rekey_final.
391 Affected files are lib/silcclient/protocol.[ch] and
392 lib/silcclient/client.[ch].
394 * Removed the `hmac_key' and `hmac_key_len' fields from the
395 SilcClientConnection structure; not needed. Affected file is
396 lib/silcclient/client.h.
400 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
402 * Do not ask whether user wants to use the negotiated private key
403 for private messages, just use it. Affected file is
404 silc/local_command.c.
406 * Added `send_enc_key' and `enc_key_len' fields to the
407 SilcIDListData structure since they are needed in the re-key
408 phase. Affected file is silcd/idlist.[ch].
410 * Implemented the simple re-key protocol into the server.
411 Affected files silcd/server.c and silcd/protocol.[ch]. The
412 re-key will be performed once in an hour, by default.
414 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
415 Added silc_server_rekey, silc_server_rekey_callback and
416 silc_server_rekey_final.
418 * Removed Tunneled flag from the protocol. Updated the code
419 and the specifications.
421 * Adde `pfs' field to the SilcIDListData to indicate whether
422 the PFS is to be performed in the re-key. Affected file is
425 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
427 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
428 int64 of at least the xintXX size. If void * is less that 4
429 bytes uint32 * will be used. Defined bool as boolean.
431 * Changed _ALL_ unsigned long and unsigned int to uint32,
432 unsgined short to uint16 in the source tree.
434 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
435 not handle clients that has entry->data.registered == FALSE.
436 They are not in the network anymore. Affected file is
439 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Implemented the sending of the SERVER_SIGNOFF notify in the
442 server. Affected file is silcd/server.c.
444 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
445 Added also silc_notify_payload_encode_args into the
446 lib/silccore/silcnotify.[ch].
448 * Implemented ther SERVER_SIGNOFF notify handling in the server.
449 Affected file silcd/packet_receive.c.
451 * Implemented the SERVER_SIGNOFF notify handling in the client
452 library. Affected file lib/silcclient/client_notify.c. Also,
453 implemnted the printing of the SERVER_SIGNOFF info to the
454 application. Affected file silc/client_ops.c.
456 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
457 if the deleting was successful. Affected file silcd/idlist.[ch].
459 * Added support for public key authentication in the connection
460 authentication protocol in the client library. Affected file
461 lib/silcclient/protocol.c.
463 * Changed the server's silc_idlist_get_clients_by_* interface
464 to support already allocated array so that new entries may be
465 added to pre-allocated array. Affected file silcd/idlist.[ch].
466 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
469 * All command reply functions in the server now calls the
470 pending command callback even if error occured. This way the
471 error will be delivered to the client as well. Affected files
472 silcd/command.c and silcd/command_reply.c.
474 * Fixed INFO command to return local server's info if no server
475 was provided. Affected file lib/silcclient/command.c.
477 * Removed RESTART command for good. Updated the code and the
480 * Rewrote parts of the task system. It is a bit simpler now.
481 Removed unsued task priorities. The affected files are
482 lib/silcutil/silctask.[ch].
484 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
486 * Moved the USERS printing from the library to the application.
487 Affected files lib/silcclient/command.c and silc/client_ops.c.
489 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Added channel key re-key support. The re-key is perfomed
494 only by the router and is done once in an hour. Added `rekey'
495 field to the SilcChannelEntry in the server. Affected files
496 silcd/server.c and silcd/idlist.h.
498 * Added silc_task_unregister_by_context into the file
499 lib/silcutil/silctask.[ch].
501 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
503 * Added SILC_UMODE_GONE mode to indicate when the client is not
504 present in the SILC network. Added also support to the local
505 command AWAY that will set this mode. Added support of showing
506 "xxx is gone" in WHOIS command. The USERS command shows the
509 * Fixed setting server and router operator privileges in the
510 server's UMODE command. Affected file silcd/command.c.
512 * Merged the SKE KE1 and KE2 payloads into one payload. The
513 new KE payload is equivalent to the old KE2 payload.
515 Cleaned up the SKE Start Payload parsing. It now uses the
516 simple buffer unformatting to do the parsing. A lot faster
519 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
520 to the SKE that is used to indicate whether both of the SKE
521 parties should perform authentication. By default only the
522 responder performs authentication. By setting this flag also
523 the initiator must do authentication. By default it is unset
524 since in normal SKE case, client to server connection, only
525 the responder should do authentication. When doing SKE between
526 two clients both should perform authentication. Updated the
527 code and the protocol specs.
529 * A little fix to IDENTIFY command in the server. Search the
530 client first by hash not nickname. Affected file is
533 * Fixed the silc_client_close_connection to support closing
534 the client to client connections wihtout deleting too much
535 data. Affected file lib/silcclient/client.c.
537 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
538 are received if protocol used to be active but is not anymore
539 the application would crash due to NULL pointer dereference.
540 Affected files silcd/server.c and lib/silcclient/client.c.
542 * Added `hash' field to the SilcClientConnection to include
543 the hash function negotiated in the SKE protocol.
545 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
546 to set the channel founder authentication data. A client can
547 claim the founder rights later by providing the authentication
548 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
549 This way the channel founder can regain the channel founder
550 privileges even it is left the channel. This works only on
551 local server and the client must be connected to the same
552 server to be able to regain the founder rights. Updated the
553 protocol specs accordingly.
555 Added support to the CMODE command in the client to set the
556 founder auth data. Read the README to see how to set it.
558 Added support to the CUMODE command to claim the founder
559 rights. Read the README to see how to do it.
561 Added support for the founder authentication to the Channel
562 Entry in the server. Affected file silcd/idlist.h.
564 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
565 server's CMODE command. Affected file silcd/command.c.
567 * Added the following new functions into lib/silccore/silcauth.[ch]:
568 silc_auth_get_method and silc_auth_get_data.
570 * The server now saves the remote hosts public key to the
571 SilcIDListData pointer. Affected file silcd/protocol.c.
573 * The normal server now does not remove the channel entry from
574 the cache if the founder authentication data is set. It used
575 to remove it if the founder was the last one on the channel on
576 the server and left the channel. The auth data is saved and
577 if the channel is re-joined later the old entry is used with
578 the old auth data. Affected files silcd/command_reply.c and
581 * Removed the `pkcs' field from the SilcIDListData structure
582 in the server; it is not used. Affected file silcd/idlist.h.
584 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
586 * Fixed packet processing on slow links. Partial packets were
587 never re-processed because the incoming data buffer was cleared
588 by the application. Application must not directly clear the
589 sock->inbuf, the packet processing routines handle it. Fixed
590 this in client library and in server.
592 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
594 * Fixed the WHOIS and IDENTIFY send reply function to really
595 check whether to send list or just one entry. Affected file
598 * Cleaned up the LEAVE command's channel key distribution. The
599 affected file silcd/command.c.
601 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
602 can enforce the channel mode as well. In that case the ID
603 includes the ID of the server. The code now enforces the
604 mode change if the router have different mode than the server.
606 * The notify client operation with CMODE_CHANGE notify can now
607 return NULL client_entry pointer if the CMODE was not changed
608 by client. Application must check for this.
610 * Added <Server ID> argument to INFO command to support server
611 info fetching by Server ID.
613 * Added silc_server_announce_get_channel_users to get assembled
614 packets of channel users of the specified channel. Affected
615 file silcd/server.[ch].
617 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
618 was freed underneath the ID Cache.
620 * Re-announce clients when the server received CHANNEL_CHANGE
621 notify from the router. Affected file silcd/packet_send.c.
623 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
625 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
626 crashed since it did not handle the fact that there is no cipher
627 called "3" and didn't check the error condition. Now fixed.
629 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
630 flag. It can be used to send message requests.
632 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
634 * Implemented the RESTART command in the client.
636 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
637 notice type messages. Added notice printing to the user
640 * The channel keys are not re-generated if the channel's mode
641 is PRIVKEY, ie private key on the channel exists. Affected
642 files silcd/server.c and silcd/command.c.
644 * Fixed a little bug in channel message delivery when channel
645 private keys are set in the server. Affected file is
648 * Changed the setting on channel->on_channel = TRUE from the
649 silc_client_save_channel_key to the JOIN command reply. The
650 key payload is not received if the private channel key is set.
651 Affected file lib/silcclient/command_reply.c and the
652 lib/silcclient/client_channel.c.
654 * When the CMODE_CHANGE notify is sent and the channel private
655 key mode is removed the channel key must be re-generated in
656 other cells as well. Added this support for the router in the
657 silcd/packet_receive.c.
659 * Added new local command NOTICE to send notice message on
660 channel. Affected file silc/local_command.[ch].
662 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
664 * Added new local command ME to the client. It is used to send
665 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
666 some action. Affected file silc/local_command.[ch].
668 * Changed channel_message and private_message client operations
669 to deliver the message flags to the application. Added also
670 the `flags' arguments to the silc_client_send_channel_message
671 and silc_client_send_private_message functions. Affected file
674 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
676 * Redefined the Private Message Payload to support private message
677 keys and to support the new private message flags. Updated
678 the protocol specs. Flags makes it possible to have for example
681 * Added new type SilcPrivateMessagePayload and defined an API
682 for it in the lib/silcclient/silcprivate.[ch].
684 * Tested private message private keys successfully. Tested the
685 private message key set, unset and list commands with the new
688 * Redefined the Channel Message Payload to include the channel
689 message flags (equal with private message flags) to support
690 for example CTCP style messages.
692 * Defined some of the message (for channel and private message)
693 flags. Updated the protocol specs and added the flags to the
694 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
696 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
698 * Added SilcKeyAgreementStatus type to the key agreement routines
699 to indicate the current status and error if one occured.
700 The status types are defined in the lib/silcclient/silcapi.h.
702 * Added new local command KEY that is used to set and unset private
703 keys for channels, set and unset private keys for private messages
704 with remote clients and to send key agreement requests and
705 negotiate the key agreement protocol with remote client. The
706 key agreement is supported only to negotiate private message keys,
707 it currently cannot be used to negotiate private keys for channels,
708 as it is not convenient for that purpose.
710 * Fixed a minor pending callback setting bug in the function
711 silc_client_get_client_by_id_resolve, now the function works.
712 Affected file lib/silcclient/idlist.c.
714 * Added function silc_net_get_local_port to get local bound
715 port by socket. Added to lib/silcutil/silcnet.[ch].
717 * Added `sockets' and `sockets_count' fields to the SilcClient
718 object. They hold the sockets of the listenning sockets in
719 the client. Listenning sockets may be for example the key
720 agreement server. Affected file lib/silcclient/client.[ch].
721 Added functions the silc_client_add_socket and the
722 silc_client_del_socket. They are exported to the application
725 * Added ~./silc/clientkeys to support other client's public keys.
727 * Renamed verify_server_key client operation to verify_public_key
728 and added one argument to indicate the type of the connection
729 (server, client etc.).
731 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
733 * Added silc_server_connection_auth_request to handle the
734 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
735 silcd/packet_receive.[ch].
737 * Added silc_server_send_connection_auth_request into the
738 silcd/packet_send.c to send the connection auth request packet.
740 * Cleaned up the silcd/protocol.c a bit and fixed some memory
743 * Fixed the public key authentication in responder side in the
744 server. The `auth_data' pointer includes the SilcPublicKey
745 not the path to the public key. Affected file silcd/protocol.c.
747 * Implemented the public key authentication in the initiator side
748 in the server. Affected file silcd/protocol.c.
750 * Removed the [RedirectClient] config section from the server
751 configuration. Is not needed and I don't want to implement it.
753 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * Cleaned up the CMODE command in the server. It now works
756 correctly and supports all the modes defined in the protocol.
757 Affected file is silcd/command.c.
759 * Added `hmac_name' field to the SilcChannelEntry in the server
760 to hold the default HMAC of the channel. It can be set when
761 creating the channel (with JOIN command). Affected files
764 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
765 type to indicate the change of the current cipher and hmac
766 on the channel. Client can safely ignore the <cipher> argument
767 (if it chooses to do so) since the CHANNEL_KEY packet will
768 force the channel key change anyway. The <hmac> argument is
769 important since the client is responsible of setting the new
770 HMAC and the hmac key into use.
772 * Fixed the CMODE command in the client library as well.
774 * Tested CMODE command in router environment successfully.
776 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
778 * Show the version of the remote client (or server) when connecting
779 to the server. It is logged to the log file. Affected file
782 * Fixed the KILLED notify handling in the client library. The
783 client must be removed from all channels when receiving the
786 Also, do not remove the client entry when giving the KILL
787 command but when the KILLED notify is received.
789 * Removed silc_idlist_find_client_by_nickname from the server.
790 Not needed anymore. Affected files silcd/idlist.[ch].
792 * Implemented the CHANNEL_CHANGE notify type handling to the
793 server. Affected file silcd/server.c.
797 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

800 notify between routers.
802 * Implemented the INVITE command correctly to the server.
804 * Implemented the INVITE notify type handling in the server.
806 * Implemented the INVITE command to the client library and on the
809 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
811 * Added function silc_server_get_client_resolve to find the
812 client entry by ID from all ID lists and then resolve it
813 (using WHOIS) if it cannot be found. Affected file is
816 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
818 * Implemented the BAN command to the client library.
820 * The JOIN command in the server now checks the invite list
823 * Changed the silc_command_reply_payload_encode_va and the
824 silc_command_payload_encode_va to support that if argument is
825 NULL it ignores and checks the next argument. Affected file
826 lib/silccore/silccommand.c.
828 * Added silc_server_send_notify_ban to send the BAN notify
829 type between routers.
831 * Chaned the silc_notify_payload_encode to support that if
832 argument is NULL it ignores and checks the next argument.
833 Affected file lib/silccore/silcnotify.c.
835 * Tested ban lists in router environment successfully.
837 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
839 * Implemented BAN command to the server, in silcd/command.[ch].
841 * Removed the BAN and INVITE_LIST modes from the CMODE command
844 * Added function silc_string_match to regex match two strings.
845 Affected files lib/silcutil/silcutil.[ch].

849 * Redefined parts of the SilcChannelEntry in the server to support
850 the new ban and invite lists.
852 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * Redefined the INVITE command. The same command can be used to
855 invite individuals to the channel but also to manage the invite
856 list of the channel (to add to and remove from the invite list).
857 Updated the protocol specs.
859 * Added new command SILC_COMMAND_BAN that can be used to manage
860 the ban list of the channel. Updated the protocol specs.
862 * Removed the channel modes: the SILC_CMODE_BAN and the
863 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
864 in the CMODE command. The equivalent features are now available
865 using INVITE and BAN commands. Updated the protocol specs.
867 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
868 in the network about change in the current ban list. The notify
869 type is not used by the client.
871 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
872 support the invite lists.
874 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
876 * Added new function silc_string_regexify that converts string
877 including wildcard characters into regex string that can
878 be used by the GNU regex library. Added into the file
879 lib/silcutil/silcutil.[ch].
881 Added silc_string_regex_combine to combine to regex strings
882 into one so that they can be used as one regex string by
883 the GNU regex library. Added into the file
884 lib/silcutil/silcutil.[ch].
886 Added silc_string_regex_match to match two strings. It returns
887 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
889 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
891 * Imported GNU regex to the soruce tree into lib/contrib.
892 Fixed some compiler warning from the regex.c.
894 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * Fixed MOTD command in the server to work in router environment.
898 * Fixed the MOTD command in the client library to support
899 the server argument in the command.
901 * Added `nickname_len' argument to the silc_idlist_add_client
902 in the server, as the `nickname' argument may be binary data
905 * Added silc_idlist_get_channels to return all channels from
908 * Implemented LIST command to the server. Affected file is
911 * Implemented the LIST command to the client library and on the
914 * Added [<user count>] argument to the LIST command reply.
915 With private channels the user count is not shown.
917 * Updated TODO and README.
919 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
921 * The client entry's data.registered must be TRUE even with
922 global client entry on global client list. The data.registered
923 is used to check whether the client is anymore in the network,
924 for example with WHOWAS command so it must be valid.
926 * Fixed the WHOWAS command in the server. It now actually works
927 in router environment. Added function into silcd/command_reply.c
928 silc_server_command_reply_whowas_save.
930 * Added silc_idlist_purge function to the silcd/idlist.c
931 to periodically purge the ID Cache.
933 * Fixed INFO command in the server. It works now in router
934 environment. Added <server name> argument to the INFO command
935 reply. Updated the protocol specs.
937 * Fixed minor bug in silc_idcache_purge to not purge if the
938 expire value is zero.
940 * Fixed various bugs in WHOIS and IDENTIFY command handling as
941 they were buggy because of the WHOWAS information.
943 * Fixed local command MSG to handle the async resolving of
944 the remote client properly. It used to fail the first MSG.
945 Affected file silc/local_command.c.
947 * Added `data_len' field to SilcIDCache context.
949 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
951 * Update TODO. Todo in commands in the server.
953 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
955 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
956 used by routers as broadcast packet to inform other routers
957 about the changed user mode.
959 Implemented the notify handling in the server. Affected file is
960 silcd/packet_receive.c. Added the function
961 silc_server_send_notify_umode to the silcd/packet_send.[ch].
963 * Added new generic Channel Payload and deprecated the New Channel
964 Payload. The New Channel Payload is now the generic Channel
967 * Added new argument `mode' to the silc_server_send_new_channel
968 as it is required in the Channel Payload now.
970 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
971 and created a new and real SilChannelPayload to represent the
972 new generic Channel Payload. Implemented the encode/decode
973 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
975 * Added silc_server_get_client_channel_list to return the list
976 of channels the client has joined for WHOIS command reply.
977 Affected file silcd/server.[ch].
979 * Implemented the channel list sending in the WHOIS command reply
980 in server and in the client.
982 Implemented the channel list displaying on the user interface
983 as well. Affected file silc/client_ops.c.
985 * Added silc_channel_payload_parse_list to parse list of Channel
986 Payloads. It returns SilcDList list of SilcChannelPayloads.
987 Client for example can use this function to parse the list of
988 channels it receives in the WHOIS command reply. The caller
989 must free the list by calling silc_channel_payload_list_free.
990 Affected files lib/silccore/silcchannel.[ch].
992 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * Added one new argument <user mode> to the WHOIS command reply
995 to return the mode of the user in SILC. Updated the protocol
998 Implemented it to the server and client.
1000 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1002 * Fixed the mode printing on the user interface on joining.
1003 Affected file silc/client_ops.c.
1005 * Implemented the UMODE command and user modes in general to the
1006 client library and to the user interface.
1008 * Implemented the UMODE command to the server.
1010 * The server now sends UNKNOWN_COMMAND error status if client sends
1011 unknown command. Affected file silcd/command.c.
1013 * All server commands now handle the command identifier the right
1014 way when sending the command reply to the client. The client can
1015 use to identify the command replies with the identifier.
1017 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1019 * Added silc_server_get_client_route to resolve the route to
1020 the client indicated by the client ID. Affected file is
1023 * Added silc_server_relay_packet as general function to relay
1024 packet to arbitrary destination. This deprecates functions
1025 like _send_private_message_key, _relay_notify etc. Affected
1026 file is silcd/packet_send.[ch].
1028 Removed silc_server_send_key_agreement,
1029 silc_server_send_private_message_key and
1030 silc_server_packet_relay_notify functions from the file
1031 silcd/packet_send.[ch].
1035 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1036 server. Affected file silcd/packet_receive.[ch].
1038 * Implemented the KILL command to the client. Implemented the
1039 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1040 Affected files lib/silcclient/command[_reply].c and
1041 lib/silcclient/client_notify.c. Implemented the KILL notify
1042 printing in the user inteface.
1044 * Fixed a lot silc_parse_nick memory leaks from the client
1045 library in the file lib/silcclient/command.c.
1047 * Changed the silc_server_send_notify_on_channels's `sender'
1048 argument from SilcSocketConnection to SilcClientEntry to
1049 check the sender as entry and not as connection object and not
1050 to send to the client provided as argument. The affected file
1051 is silcd/packet_send.[ch].
1053 * The notify packets that are destined directly to the client used
1054 to not to be processed by the server. Now changed that and the
1055 server processes all notify packets. After relaying the packet
1056 to the client the notify packet is processed in the server.
1058 * The silc_server_free_client_data now checks whether there is
1059 pending outgoing traffic for the client and purges the data to
1060 the network before removing the client entry.
1062 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1064 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1065 an client is killed from the SILC Network. Updated the protocol
1068 Added new function silc_server_send_notify_killed to the
1069 silcd/packet_send.[ch].
1071 * Added function silc_server_packet_relay_notify to relay notify
1072 packets that are destined directly to a client. In this case
1073 the server does not process the notify packets but merely relays
1074 it to the client. Affected file silcd/packet_send.[ch].
1076 Added also silc_server_packet_process_relay_notify to check
1077 whereto relay the notify. Affected file is
1078 silcd/packet_receive.[ch].
1080 * Implemented the KILL command to the server.
1084 * Added the backup schema desgined last fall to the protocol
1085 specs for everyone to see. The specification is in the
1086 *-spec-xx.txt draft and the packet type definitions for the
1087 backup routers is in *-pp-xx.txt draft. Thusly, added also
1088 new packet type SILC_PACKET_CELL_ROUTERS.
1090 * A big security problem in the implementation discovered. The
1091 signoff of an client did not cause new channel key generation
1092 which it of course should've done. The channel keys must be
1093 always re-generated when client leaves (or signoffs) the channel.
1094 The silc_server_remove_from_channels funtion now handles
1095 the channel key re-generation.
1097 * Added `sender' argument to the silc_server_send_notify_on_channels
1098 to not to send the client provided as argument. Affected file
1099 silcd/packet_send.[ch].
1101 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1103 * Implemented OPER and SILCOPER commands into the server and
1106 * Added silc_auth_verify and silc_auth_verify_data to verify
1107 the authentication directly from the authentication payload.
1108 It supports verifying both passphrase and public key based
1109 authentication. Affected file lib/silccore/silcauth.[ch].
1111 * Added `hash' field to the SilcIDListData structure. It is the
1112 hash negotiated in the SKE protocol. Affected file is
1115 * Slight redesigning of the SilcAuthPayload handling routines.
1116 Do not send SilcPKCS but SilcPublicKey as argument.
1118 * Implemented the public key authentication support to the
1119 serverconfig. The public key is loaded from the provided path
1120 and saved as authentication data to void * pointer. Thus,
1121 changed the unsigned char *auth_data to void *auth_data;
1123 * Fixed SHUTDOWN command to send the reply before the server
1124 is shutdown. :) Affected file silcd/command.c.
1126 * Fixed fatal bug in CONNECT command. The hostname was invalid
1127 memory and server crashed. Affected file silcd/command.c.
1129 * Fixed fatal bug in CLOSE command. The server_entry became
1130 invalid but was referenced later in the command. Affected file
1133 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1135 * Fixed fatal bug in failure packet handling. Server ignored
1136 the failure and thus crashed when it came.
1140 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1142 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1143 that the command may be executed only once in (about) 2 seconds.
1144 The old SILC_CF_LAG flag is same but allows command bursts up
1145 to five before limiting.
1147 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1148 server code. Various commands now includes the CF_LAG_STRICT
1149 flag to disallow any kind of miss-use of the command.
1151 * Fixed the silc_buffer_unformat to not to allocate any data
1152 if the length of the data is zero. It used to allocate the
1153 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1155 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1157 * Changed the format of AdminConnection configuration section
1158 in the server. Added username of the admin to the format.
1159 Affected files silcd/serverconfig.[ch].
1161 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1162 to return admin configuration data by host, username and/or
1165 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1167 * Implemented WHOWAS command to the server. Added the functions:
1169 silc_server_command_whowas_parse,
1170 silc_server_command_whowas_send_reply,
1171 silc_server_command_whowas_from_client and
1172 silc_server_command_whowas_from_server
1174 * Added <Client ID> argument to the WHOWAS command reply. Updated
1175 the protocol specs accordingly.
1177 * Implemented WHOWAS command and command_reply to the client
1180 Implemented the WHOWAS printing on the user interface.
1182 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * Added new argument to the WHOWAS command reply, the real name.
1185 It is an optional argument. Updated the protocol specs.
1187 * Added SilcIDCacheDestructor callback that is registered when
1188 the SilcIDCache is allocated. The callback is called when
1189 an cache entry in the ID Cache expires, or is purged from the
1190 cache. Added into lib/silccore/idcache.[ch].
1192 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1193 to destruct the client entries when the cache entry expires.
1194 Other ID Cache's in server and in the client library ignores
1197 * If the ID Cache entry's `expire' field is zero then the entry
1198 never expires. Added boolean `expire' argument to the
1199 silc_idcache_add function in the lib/silccore/idcache.[ch].
1200 If it is TRUE the default expiry value is used.
1202 * Added silc_server_free_client_data_timeout that is registered
1203 when client disconnects. By default for 5 minutes we preserve
1204 the client entry for history - for WHOWAS command.
1206 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1208 * Added support to the server to enforce that commands are not
1209 executed more than once in 2 seconds. If server receives
1210 commands from client more frequently, timeout is registered
1211 to process the commands. Affected file silcd/command.c.
1212 Added new function silc_server_command_process_timeout.
1214 * Changed NICK_NOTIFY handling in client library to check that
1215 if the client's nickname was changed, so there is no need to
1216 resolve anything from the server.
1218 * Removed error printing from the WHOIS and IDENTIFY commands.
1219 If error occurs then it is ignored silently in the client library.
1220 The application, however, may map the received error to
1221 human readable error string. The application currently maps
1222 the NO_SUCH_NICKNAME error to string.
1224 * Made the command status message public to the application. Moved
1225 them from lib/silcclient/command_reply.c to
1226 lib/silcclient/command_reply.h. The application can map the
1227 received command status to the string with the
1228 silc_client_command_status_message function.
1230 * Added check to the server to check that client's ID is same
1231 as the Source ID in the packet the client sent. They must
1234 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1236 * Added dist-bzip hook to the Makefile.am to make bzip2
1237 compressed distributions.
1239 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1241 * Server now enforces the maximum length for the nickname and
1242 the channel as protocol specification dictates. 128 bytes for
1243 nickname and 256 bytes for channel name.
1245 * Moved the WHOIS printing to the application. The client libary
1246 does not print out the WHOIS information anymore, the application
1247 must do it. Renamed silc_client_command_reply_whois_print to
1248 the silc_client_command_reply_whois_save.
1250 The client's idle time is also sent to the application now, and
1251 the idle is shown on screen.
1253 * Added silc_client_command_reply_identify_save to save the
1254 received IDENTIFY entries.
1256 * Do not check for channel private keys in message sending and
1257 reception if the channel does not have the PRIVKEY mode set.
1258 Affected file lib/silclient/client_channel.c.
1260 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1263 just surfaced after chaning the JOIN procedure.
1265 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1267 * Added silc_client_get_clients_by_list to get client entries
1268 from Client ID list, that is returned for example by JOIN
1269 and USERS command replies. The application should use this
1270 function for example when JOIN command reply is received to
1271 resolve the clients already on the channel (library does not
1272 do that anymore as USERS command reply is not used in the JOIN
1273 procedure anymore). Affected files lib/silcclient/silcapi.h and
1274 lib/silcclient/idlist.c.
1276 * JOIN command reply and USERS command reply returns now SilcBuffer
1277 pointers instead of unsigned char pointers when returning
1278 the client list and mode list.
1280 * Added <Client ID> argument to the JOIN command reply, mainly
1281 for the server to identify for which client the command was
1282 originally sent. Updated protocol specs accordingly.
1284 * Added SilcDlist private_key pointer to the SilcChannelEntry
1285 in the client to support the channel private keys. Affected
1286 file is lib/silcclient/idlist.h.
1288 * Added SilcChannelPrivateKey argument to the function
1289 silc_client_send_channel_message so that application can choose
1290 to use specific private ke if it wants to. If it is not provided,
1291 the normal channel key is used, unless private keys are set.
1292 In this case the first (key that was added first) is used
1293 as the encryption key.
1295 * Implemented the support for channel private key handling.
1296 Implemented the following functions:
1298 silc_client_add_channel_private_key,
1299 silc_client_del_channel_private_keys,
1300 silc_client_del_channel_private_key,
1301 silc_client_list_channel_private_keys and
1302 silc_client_free_channel_private_keys
1304 Affected file lib/silcclient/client_channel.c.
1306 * Added the support for the private keys in the channel message
1307 sending and encryption and in the message reception and
1308 decryption. Affected funtions are
1309 silc_client_send_channel_message and silc_client_channel_message.
1311 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1313 * Added SKE's key verify callback to the client library's
1314 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1316 * Removed the statement that server (or router) must send USERS
1317 command reply when joining to the channel so that the client
1318 knows who are on the channel. Instead, the client list and
1319 client's mode list is now sent in the JOIN command reply to the
1320 client who joined channel. This is better solution.
1322 * Added function silc_server_get_users_on_channel and function
1323 silc_server_save_users_on_channel to the silcd/server.[ch].
1325 * Removed function silc_server_command_send_users from the
1328 * Do not show topic on the client library anymore. The topic is
1329 sent in the command reply notify to the application and the
1330 application must show the topic now.
1332 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1334 * Added client searching by nickname hash into the IDENTIFY and
1335 WHOIS commands in the server as they were clearly missing from
1336 them. Affected file is silcd/command.c.
1338 * Fixed a bug in private message receiving in the client library.
1339 The remote ID was freed and it wasn't supposed, now it is
1342 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1344 * Minor fix to the channel payload; allocate the data area, as it
1345 needs to be of specific length.
1347 * If the key agreement port is zero then the operating
1348 system will define the bound port. Affected files are
1349 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1351 * Added new function silc_channel_payload_decrypt into the file
1352 lib/silccore/silcchannel.[ch].
1354 * Moved the channel message etc, check from silc_packet_decrypt
1355 to applications. The library calls now a generic
1356 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1357 when the packet is either normal or special. This was done to
1358 allow more wide range of checking that was not allowed when
1359 the code was in library. Now applications can do virtually any
1360 checks to the packet and return to the library the decision how
1361 the packet should be processed. Affected files are
1362 lib/silccore/silcpacket.[ch].
1364 Added silc_server_packet_decrypt_check to the server and
1365 silc_client_packet_decrypt_check to the client library.
1367 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1368 to send with specified source and destination information.
1370 * Channel message delivery between routers was broken after the
1371 channel key distribution was fixed earlier. The channel key
1372 was used be to distributed to other routers as well which is not
1373 allowed by the protocol. Now this is fixed and channel keys
1374 really are cell specific and the channel message delivery between
1375 routers comply with the protocol specification.
1377 * Fixed various commands in server to check also the global list
1378 for the channel entry and not just the local list. The affected
1379 file silcd/command.c.
1381 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Added assert()s to buffer formatting and unformatting routines
1384 to assert (if --enable-debug) when error occurs. Affected
1385 file: lib/silcutil/silcbuffmt.c.
1387 * Changed to auto-reconnect to check whether the remote host is
1388 router and register the re-connect timeout if it is. It used
1389 to check that whether we are normal server, but router must do
1390 auto-reconnect with another router as well. Affected file
1393 * Removed the [<key len>] option from CMODE command as the cipher
1394 name decides the key length, nowadays. See the defined ciphers
1395 from the protocol specification.
1397 * Added [<hmac>] option to the CMODE command to define the HMAC
1398 for the channel. Added SILC_CMODE_HMAC channel mode.
1400 * Added [<hmac>] option for the JOIN command so that user can
1401 select which HMAC is used to compute the MACs of the channel
1404 * Added Hmac field to the Channel Message Payload. The integrity
1405 of plaintext channel messages are now protected by computing
1406 MAC of the message and attaching the MAC to the payload. The
1407 MAC is encrypted. Now, it is clear that this causes some
1408 overhead to the size of the packet but rationale for this is that
1409 now the receiver can verify whether the channel message decrypted
1410 correctly and also when private keys are set for the channel the
1411 receiver can decrypt the packet with several keys and check from
1412 the MAC which key decrypted the message correctly.
1414 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1415 lib/silccrypt/silccipher.[ch].
1417 * Added silc_hash_len to return the digest length into the
1418 lib/silcrypt/silchash.[ch].
1420 * Rewrote parts of Silc Channel Payload interface in the
1421 lib/silccore/silcchannel.[ch]. The encode function now also
1422 encrypts the packet and parse function decrypts it.
1424 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1426 * Fixed a minor formatting bug in the SKE's key material processing.
1427 It actually might have processed the keys wrong way resulting
1430 * Redefined the mandatory HMAC algorithms and added new algorithms.
1431 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1432 and hmac-md5 truncated to 96 bits. The mandatory is now
1433 hmac-sha1-96. Rest are optional (including the one that used
1434 to be mandatory). Rationale for this is that the truncated HMAC
1435 length is sufficient from security point of view and can actually
1436 make the attack against the HMAC harder. Also, the truncated
1437 HMAC causes less overhead to the packets. See the RFC2104 for
1440 * Added new [hmac] configuration section. The SKE used to use
1441 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1442 is of course wrong. The official names that must be proposed in
1443 the SKE are the ones defined in the protocol specification
1444 (hmac-sha1-96 for example). The user can configure any hmac
1445 using any hash function configured in the [hash] section. At
1446 least, the mandatory must be configured.
1448 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1450 * Added HMAC list to the SKE proposal list. It has now both
1451 hash algorithm list and HMAC list. This makes the protocol
1452 incompatible with previous versions. The SKE now seems to work
1453 the way it is supposed to work, for the first time actually.
1455 * Defined plain Hash algorithms to the protocol specification.
1458 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1460 * Implemented support for key agreement packets into the server.
1461 Added functions silc_server_key_agreement and
1462 silc_server_send_key_agreement. Other than these functions,
1463 server has nothing to do with this packet.
1465 * Added support for private message key packets into the server.
1466 Added functions silc_server_private_message_key and
1467 silc_server_send_private_message_key.
1471 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1472 called in the protocol's final callback instead in the END
1473 protocol state. This makes a little more sense and in the same
1474 time in client we can use the same protocol routines for normal
1475 key exchange and to key agreement packet handling as well.
1477 * Added to both client's and server's KE protocol context the
1478 SilcSKEKeyMaterial pointer to save the key material. We will
1479 bring the key material to the protocol's final callback by doing
1480 this. The final callback must free the key material.
1482 * Added SKE's packet_send callback into client's KE protocol
1483 context so that the caller can choose what packet sending function
1484 is used. This way we can use different packet sending when
1485 doing normal SKE when doing key agreement packet handling (in
1486 the key agreement packet handling we do not want to encrypt
1489 * Implemented the responder side of the key agreement routines
1490 in the client. The client can now bind to specified port and
1491 accept incoming key negotiation. The key material is passed
1492 to the application after the protocol is over.
1494 * Implemented the processing of incoming Key Agreement packet
1495 in the client. Added function silc_client_key_agreement to
1498 * Implemented the intiator side of the key agreement routines
1499 in the client. The client can now initiate key agreement with
1500 another remote client. The key material is passed to the
1501 application after the protocol is over.
1503 * Created client_keyagr.c to include all the key agreement
1506 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1507 SILC_TASK_CALLBACK except that it is not static.
1509 * Created client_notify.c and moved the Notify packet handling
1510 from the client.[ch] into that file.
1512 * Created client_prvmsg.c and moved all private message and
1513 private message key routines from the client.[ch] into that file.
1515 * Create client_channel.c and moved all channel message and
1516 channel private key routines from the client.[ch] into that file.
1518 * Changed silc_client_get_client_by_id_resolve to resolve with
1519 WHOIS command instead of IDENTIFY command, in the file
1520 lib/silclient/idlist.c.
1522 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1524 * Implemented the SKE's responder side to the Client library.
1526 * When FAILURE is received to the protocol do not trust it
1527 blindly. Register a timeout to wait whether the remote closes
1528 the connection as it should do it, only after that process the
1529 actual failure. This was changed to both client and server.
1531 * Added client_internal.h to include some of the structures
1532 there instead of client.h in lib/silcclient/.
1534 * Added function silc_task_unregister_by_callback to unregister
1535 timeouts by the callback function.
1537 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1539 * Some "Incomplete WHOIS info" errors has been appearing on the
1540 log files. Took away the entry->userinfo check from WHOIS
1541 reply sending. The entry->userinfo is now " " if client did not
1542 provide one. I thought this was fixed earlier but something
1543 is wrong still. Let's see if the error still appears.
1545 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Fixed a minor bug in the login when the channel key is
1548 re-generated in the server. It used to generate the key in
1549 wrong order and thus caused problems in the channel traffic.
1551 * Fixed a minor bug in channel key distsribution after
1552 KICK command. The key was not sent to the router even though
1555 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1557 * Added silc_ske_process_key_material_data as generic routine
1558 to process any key material as the SILC protocol dictates. The
1559 function is used by the actual SKE library but can be used by
1560 applications as well. This relates to the private message keys
1561 and the channel private keys since they must be processed the
1562 same way the normal SILC session keys. The protocol dictates
1563 this. Affected files: lib/silcske/silcske.[ch].
1565 Added also silc_ske_free_key_material to free the
1566 SilcSKEKeyMaterial structure.
1568 * Defined silc_cipher_set_key function to set the key for
1569 cipher without using the object's method function. The affected
1570 files: lib/silccrypt/silccipher.[ch].
1572 * Implemented silc silc_client_add_private_message_key,
1573 silc_client_add_private_message_key_ske,
1574 silc_client_del_private_message_key,
1575 silc_client_list_private_message_keys and
1576 silc_client_free_private_message_keys functions in the
1579 Added functions silc_client_send_private_message_key to send
1580 the Private Message Key payload and silc_client_private_message_key
1581 to handle incoming Private Message Key payload.
1583 * Added Cipher field to the Private Message Key payload to set
1584 the cipher to be used. If ignored, the default cipher defined
1585 in the SILC protocol (aes-256-cbc) is used.
1587 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1589 * Removed lib/silcclient/ops.h file.
1591 Redefined parts of the SILC Client Library API. Created new
1592 file silcapi.h that deprecates the ops.h file and defines the
1593 published Client Library API. Defined also private message key
1594 API and channel private key API into the file.
1596 This is the file that the application must include from the
1597 SILC Client Library. Other files need not be included by
1598 the application anymore.
1600 * Added new key_agreement client operation callback and also
1601 defined the Key Agreement library API for the application.
1603 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1605 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1606 is used by clients to request key negotiation between another
1607 client in the SILC network. If the negotiation is started it
1608 is performed using the SKE protocol. The result of the
1609 negotiation, the secret key material, can be used for example
1610 as private message key.
1612 Implemented the Key Agreement payload into the files
1613 lib/silccore/silauth.[ch].
1615 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1617 * Redefined ciphers for the SILC protocol. Added some new ciphers
1618 and defined the key lengths for the algorithms. Changed the
1619 code accordingly. The default key length is now 256 bits.
1621 * Fixed SKE key distribution function silc_ske_process_key_material
1622 when the key length is more than 128 bits. The default key
1623 length in SILC is now 256 bits.
1625 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1626 to indicate unsupported algorithm.
1628 * Renamed rijndael.c to aes.c and all functions as well.
1630 * Fixed a long standing channel key setting bug in client library.
1631 Weird that it has never surfaced before.
1633 * Fixed bug in channel deletion. If the entire channel is removed
1634 then it must also delete the references of the channel entry
1635 from the client's channel list as the client's channel entry and
1636 the channel's client entry share same memory.
1638 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1640 * Implemented CONNECT and SHUTDOWN commands in the client.
1642 * Implemented CLOSE command to the client.
1644 * Added the function silc_idlist_find_server_by_name into the
1645 files silcd/idlist.[ch].
1647 Added the function silc_idlist_find_server_by_conn into the
1648 files silcd/idlist.[ch].
1650 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1652 * DIE command was renamed to SHUTDOWN. Updated the both code
1655 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1656 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1658 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1661 * Added function silc_server_create_connection function to create
1662 connection to remote router. My server implementation actually
1663 does not allow router to connect to normal server (it expects
1664 that normal server always initiates the connection to the router)
1665 so the CONNECT command is only good for connecting to another
1668 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1671 or some other client was kicked from the channel.
1673 Implemented the handling of the notify type to both client
1676 Implemented silc_server_send_notify_kicked to send the KICKED
1677 notify. It is used to send it to the server's primary router.
1679 * Implemented the KICK command into server and client.
1681 * Added `query' argument to the silc_idlist_get_client function
1682 to indicate whether to query the client from server or not if
1685 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1686 to indicate that the client is not channel founder.
1690 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1692 * Removed the rng context from SilcPacketContext structure and
1693 changed that the packet routine uses the Global RNG API.
1695 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1697 * Added support for quit message that client can "leave" on the
1698 channel when it quits the SILC. It is ditributed inside the
1699 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1701 Added silc_server_free_client_data that will take the
1702 signoff message as argument.
1704 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1706 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1708 * Updated parts of the protocol specification to keep it up
1711 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1713 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1714 payloads in one packet.
1716 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1717 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1718 use now the new List flag.
1720 * Also deprecated the following packet types: REPLACE_ID,
1721 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1723 * Added list support for Notify packet in server.
1725 * Added silc_server_send_notify_channel_change to send the
1726 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1727 the silc_server_send_replace_id.
1729 * Added silc_server_send_notify_nick_change to send the
1730 NICK_CHANGE notify type. Deprecates the function
1731 silc_server_send_replace_id.
1733 * Added silc_server_send_notify_join to send the JOIN notify type.
1734 Deprecates the function silc_server_send_new_channel_user.
1736 * Added silc_server_send_notify_leave to send LEAVE notify type.
1737 Deprecates the function silc_server_send_remove_channel_user.
1739 * Added silc_server_send_notify_cmode and
1740 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1741 types. Deprecates the silc_server_send_set_mode function.
1743 * Added SERVER_SIGNOFF notify type to indicate that server has
1744 quit. This means that all clients on the channel from that
1745 server will drop. This can be also used when netsplit happens.
1747 Deprecated REMOVE_ID packet type since it is not needed anymore
1750 Added silc_server_send_notify_server_signoff to send the
1751 SERVER_SIGNOFF notify type. Deprecates the function
1752 silc_server_send_remove_id.
1754 Added also silc_server_send_notify_signoff to send the
1755 SIGNOFF notify type.
1757 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1758 SILC protocol from this day on. Changed the protocol
1759 specification as well.
1761 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1762 notify type. It is used between routers to notify about
1763 topic changes on a channel.
1765 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1768 * Partly updated the protocol specification to comply with the
1769 changes now made. It is still though a bit outdated.
1771 * The JOIN notify type now takes one extra argument <Channel ID>.
1772 The packet used to be destined to the channel but now the
1773 JOIN type may be sent as list thus it is impossible to
1774 destine it to any specific channel. By adding this argument
1775 it is again possible.
1777 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1779 * Added CREDITS file. The CHANGES and CREDITS file will appear
1780 in the distribution as well.
1782 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1784 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1785 types in the server's silcd/packet_receive.c.
1787 * Implemented CMODE and CUMODE to work in router environment.
1789 * Fixed minor encoding and decoding buglet from the
1790 lib/silccore/silcmode.c.
1792 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1795 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1797 * Changed all SilcConfigServer* and silc_config_server* to
1798 SilcServerConfig* and silc_server_config*, respectively.
1801 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1803 * Associated the ID (client or server ID) to the Authentication
1804 Payload to avoid any possibility of forging. Updated the
1805 protocol specification and the code accordingly.
1807 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1809 * The RSA key length is now save to the RsaKey context in the
1810 key generation process in lib/silccrypt/rsa.c. The key length
1811 is now used to figure out the maximum size of the block allowed
1812 to be encrypted/signed.
1814 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1815 is equivalent to the silc_mp_mp2bin but does not allocate any
1818 * Changed silc_mp_mp2bin API to take length argument. If it is
1819 non-zero then the buffer is allocated that large. If zero, then
1820 the size is approximated using silc_mp_sizeinbase, which however
1823 * Created Global RNG API which is global RNG that application can
1824 initialize. After initializing, any routine anywhere in the
1825 code (including library) can use RNG without allocating a new
1826 RNG object. This was done to allow this sort of use of the
1827 RNG in code that has no chance to allocate RNG object. All
1828 applications currently allocate this and many routines in the
1829 library use this. Affected file lib/silccrypt/silcrng.[ch].
1831 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1832 it to use the Global RNG API.
1834 * Defined Authentication Payload into protocol specification that
1835 is used during SILC session to authenticate entities. It is
1836 used for example by client to authenticate itself to the server
1837 to obtain server operator privileges.
1839 Implemented this payload into the lib/silccore/silcauth.[ch].
1840 Implemented also routines for public key based authentication
1841 as the new protocol specification dictates.
1843 Moved definitions of different authentication methods from
1844 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1846 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1847 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1848 silc_pkcs_verify_with_hash functions into the file
1849 lib/silccrypt/silcpkcs.[ch].
1851 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1853 * The client entry's userinfo pointer must be always valid.
1854 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1855 will fail since it requires the userinfo. Now, the userinfo
1856 is allocated as "" if actual userinfo does not exist. Actually,
1857 it must exist and it is totally Ok to drop client connections
1858 that does not announce the userinfo. However, we will make
1859 this workaround for now.
1861 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1862 to return the remote port by socket.
1864 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1866 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1867 SILC_SERVER_PENDING_EXEC and added an new macro
1868 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1869 data or when error occurs while processing the pending command.
1871 Added new argument `destructor' into silc_server_command_pending
1872 and to the SilcServerCommandPending object. This destructor is
1873 now called after calling the pending callback or if error occurs
1874 immediately. If error occurs the actual pending callback won't
1875 be called at all - only the destructor. The destructor may be
1876 NULL if destructor is not needed.
1878 All this applies for client library code as well. Similar
1879 changes were made there as well for the pending commands.
1881 In the client, the application must now allocate the
1882 SilcClientCommandContext with the silc_client_command_alloc
1885 * Added reference counter to the SilcServerCommandContext. Added
1886 function silc_server_command_alloc and silc_server_command_dup
1889 Same type of functions added to the client library for the same
1892 * Removed the cmd_ident from IDListData away since it is now
1893 global for all connections. It is the command identifier used
1894 in command sending and with pending commands. The affected file
1897 * Added reference counter to the SilcSocketConnection objecet to
1898 indicate the usage count of the object. The object won't be
1899 freed untill the reference counter hits zero. Currently only
1900 server uses this, and client ignores it. The client must be
1901 set to use this too later. The affected files are
1902 lib/silccore/silcsockconn.[ch]. Added also the function
1903 silc_socket_dup to increase the reference counter.
1905 This was mainly added because it is possible that the socket
1906 is removed underneath of pending command or other async
1907 operation. Now it won't be free'd and proper DISCONNECTING
1908 flags, etc. can be set to avoid sending data to connection that
1909 is not valid anymore.
1911 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1912 the connection. After that it sets SILC_SET_DISCONNECTED.
1913 It is, however, possible that the socket data is not still freed.
1914 The silc_server_packet_process now checks that data is not
1915 read or written to connection that is DISCONNECTED. The socket
1916 get's freed when the reference counter hits zero.
1918 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Changed the client operation API: channel_message operation's
1921 `sender' is now the client entry of the sender, not the nickname
1922 and the `channel' is the channel entry, not the channel name.
1924 In the private_message operation the `sender' is now also the
1925 client entry of the sender not the nickname.
1927 Affected file is lib/silcclient/ops.h and all applications
1928 using the client operations.
1930 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1932 * Moved the calling of ops->connect() from connect_to_server_final
1933 into receive_new_id functin since that is the point when the
1934 client is actually allowed to send traffic to network. The
1935 affected file is lib/silcclient/client.c.
1937 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1939 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1940 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1941 (if needs broadcasting) instead of broadcasting the packets one
1942 by one which would make a burst in the network traffic.
1944 * Added `broadcast' argument to the functions in silcd/server.[ch]
1945 silc_server_create_new_channel[_with_id] to indicate whether
1946 to send New Channel packet to primary router.
1948 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Added new function into the silcd/server.[ch] files:
1951 silc_server_create_new_channel_with_id to create new channel with
1952 already existing Channel ID.
1954 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1955 lib/silccore/silcpacket.h. This packet is used t send list of
1956 Set Mode payloads inside one packet. Server uses this to set
1957 the modes for the channels and clients on those channels, that it
1958 announced to the router when it connected to it. The protocol
1959 specification has been updated accordingly.
1961 * The silc_server_new_channel did not handle the packet coming
1962 from normal server as it normally does not send that. However,
1963 when it announces its channels it does send it. Implemented
1964 the support for that.
1966 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1967 into the file lib/silccore/id.h.
1969 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1971 * Fixed memory leaks in the functions silc_idlist_del_client,
1972 silc_idlist_del_channel and silc_idlist_del_server in the file
1973 silcd/idlist.c. All of those leaked like a sieve.
1975 * Fixed some small memory leaks in the client's function
1976 silc_client_notify_by_server.
1978 * Added functions into silcd/server.c: silc_server_announce_clients,
1979 silc_server_announce_channels and silc_server_announce_server.
1980 These functions are used by normal and router server to announce
1981 to its primary router about clients, channels and servers (when
1982 router) that we own. This is done after we've connected to the
1985 These functions effectively implements the following packet types:
1986 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1987 and SILC_PACKET_NEW_ID_LIST.
1989 * Added new functions into the silcd/packet_receive.[ch]:
1990 silc_server_new_id_list, silc_server_new_channel_list and
1991 silc_server_new_channel_user_list to handle the incoming
1992 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1994 * Added support of changing Channel ID in the function
1995 silc_server_replace_id. If the server that announces a channel
1996 to the router already exists in the router (with same name but
1997 with different Channel ID), router is responsible to send
1998 Replace ID packet to the server and force the server to change
1999 the Channel ID to the one router has.
2001 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2002 client that the Channel ID has been changed by the router. The
2003 normal server sends this to the client. Client must start using
2004 the new Channel ID as the channel's ID.
2006 Implemented handling of this new type into lib/silcclient/client.c
2007 into the function silc_client_notify_by_server.
2009 * Added new function silc_idlist_replace_channel_id into the files
2010 silcd/idlist.[ch] to replace the Channel ID.
2012 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2014 * Call silc_server_command_identify_check always when processing
2015 the IDENTIFY command in silcd/command.c
2017 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2019 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2020 send keepalive packets. The packet can be sent by clients,
2021 servers and routers.
2023 Added function silc_socket_set_heartbeat into the file
2024 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2025 If not set, the heartbeat is not performed. The actual
2026 heartbeat is implemented in the low level socket connection
2027 library. However, application is responsible of actually
2030 Added silc_server_send_heartbeat to send the actual heartbeat
2031 packet into silcd/packet_send.[ch]. Server now performs
2032 keepalive with all connections.
2034 * Added silc_task_get_first function into lib/silcutil/silctask.c
2035 to return the timeout task with shortest timeout. There was a bug
2036 in task unregistration that caused problems. TODO has been
2037 updated to include that task system must be rewritten.
2039 * The client library will now resolve the client information when
2040 receiving JOIN notify from server for client that we know but
2041 have incomplete information.
2043 * Rewrote parts of silc_server_remove_from_channels and
2044 silc_server_remove_from_one_channel as they did not remove the
2045 channel in some circumstances even though they should've.
2047 * Encryption problem encountered in server:
2049 The LEAVE command used to send the Channel Key packet to the
2050 router immediately after generating it. However, the code
2051 had earlier sent Remove Channel user packet but not immediately,
2052 ie. it was put to queue. The order of packets in the router
2053 was that Channel Key packet was first and Remove Channel User
2054 packet was second, even though they were encrypted in the
2055 reverse order. For this reason, MAC check failed. Now, this
2056 is fixed by not sending the Channel Key packet immediately but
2057 putting it to queue. However, this is more fundamental problem:
2058 packets that are in queue should actually not be encrypted
2059 because packets that are sent immediately gets encrypted
2060 actually with wrong IV (and thus MAC check fails). So, packets
2061 that are in queue should be encrypted when they are sent to
2062 the wire and not when they put to the queue.
2064 However, the problem is that the current system has not been
2065 designed to work that way. Instead, the packet is encrypted
2066 as soon as possible and left to the queue. The queue is then
2067 just purged into wire. There won't be any fixes for this
2068 any time soon. So, the current semantic for packet sending
2071 o If you send packet to remote host and do not force the send
2072 (the packet will be in queue) then all subsequent packets to the
2073 same remote host must also be put to the queue. Only after the
2074 queue has been purged is it safe again to force the packet
2077 o If you send all packets immediately then it safe to send
2078 any of subsequent packets through the queue, however, after
2079 the first packet is put to queue then any subsequent packets
2080 must also be put to the queue.
2082 Follow these rules and everything works fine.
2084 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2086 * Added new function silc_server_remove_clients_by_server to
2087 remove all client entries from ID list when the server connection
2088 is lost. In this case it is also important to invalidate all
2089 client entires as they hold the invalid server entry. This
2090 fixes fatal bug when server has lost connection and will reconnect
2093 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2095 * Made some sanity checks to silc_server_daemonise like to check
2096 whether the requested user and group actually exists.
2098 * Added sanity check to SKE's silc_ske_responder_finish to check
2099 that the public and private key actually is valid.
2101 * Invalidate the client's nickname when receiving Replace ID
2102 packet and the Client ID is being replaced. This means that the
2103 server will query the nickname if someone needs it (client)
2106 * Sort the ID Cache in client library when the ID Cache data
2107 has changed (needs sorting).
2109 * Do not allow for SILC client to create several connections to
2110 several servers. The client does not support windows right now
2111 and generating multiple connections causes weird behaviour.
2113 Irssi-silc client does support windows and can handle several
2114 connections without problems, see: www.irssi.org and SILC plugin.
2116 * Fixed some places where client was added to the IDList. The
2117 rule of thumb is following (in order to get everything right):
2118 If the client is directly connected local client then the
2119 `connection' argument must be set and `router' argument must be
2120 NULL to silc_idlist_add_client function. If the client is not
2121 directly connected client then the `router' argument must
2122 bet set and the `connection' argument must be NULL to the
2123 silc_idlist_add_client function.
2125 * The funtion silc_server_packet_send_local_channel actually did
2126 not check whether the client was locally connected or not. It
2127 does that now. Fixed a bug related to LEAVE command.
2129 * Fixed Remove Channel User payload parsing bug in server's
2130 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2132 * The server's silc_server_save_channel_key now checks also the
2133 global ID list for the channel as it might not be in the local
2134 list. Fixed a bug related to LEAVE command.
2136 * Is this the end of the [<unknown>] buglet that has been lurking
2137 around for a long time? A little for loop fix in server's
2138 silc_server_command_whois_parse that is used by both IDENTIFY
2139 and WHOIS command. At least, this was a clear bug and a cause
2140 of one type of [<unknown>] buglet.
2142 * WHOIS and IDENTIFY commands call the function
2143 silc_server_command_[whois/identify]_check function even if
2144 we are not router server.
2146 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Added --with-gmp configuration option. If set the GMP
2149 is always compiled in the SILC source tree. If not set then
2150 it is checked whether the system has the GMP3 installed. If
2151 it has then the GMP won't be compiled (the system's headers
2152 and library is used), if it doesn't have it then the GMP is
2153 compiled in the SILC source tree.
2155 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2157 * Changed RSA private exponent generation to what PKCS #1
2158 suggests. We try to find the smallest possible d by doing
2159 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2160 not security fix but optimization.
2162 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2164 * Added new config entry [Identity] to fork the server and run
2165 it as specific user and group. A patch from Bostik.
2167 * Imported Dotconf configuration library into lib/dotconf.
2168 This will be used to create the SILC configuration files later.
2169 It will appear in the distsribution after this commit.
2171 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2173 * A big code auditing weekend happening. Auditing code for
2174 obvious mistakes, bugs and errors. Also, removing any code
2177 Removed files for being obsolete:
2179 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2180 inline in the file lib/silcutil/silcbuffer.h)
2182 o lib/silcutil/silcbufutil.c (the header has inline versions)
2184 Changed code to fix possible error conditions:
2186 o The buffer formatting routines now check that the destination
2187 buffer really has enough space to add the data. This applies for
2188 both buffer formatting and unformatting
2189 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2190 unformatting was changed to accomodate following rules:
2191 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2192 sent to the function while XXX_*STRING will not allocate or copy
2193 the data into the buffer. Instead it sets the pointer from the
2194 buffer into the pointer sent as argument (XXX_*STRING used to
2195 require that the pointer must be allocated already). This change
2196 makes this whole thing a bit more consistent and more optimized
2197 (note that the data returned in the unformatting with XXX_*STRING
2198 must not be freed now). The routines return now -1 on error.
2200 o Tried to find all code that use buffer_format and buffer_unformat
2201 and added return value checking to prevent formatting and
2202 especially unformatting errors and possible subsequent fatal
2205 o Changed ske->x and ske->KEY to mallocated pointers in
2206 lib/silcske/silcske.h. Fixed possible data and memory leak.
2208 o Added return value checking to all *_parse* functions. Fixed
2209 many memory leaks as well.
2211 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2212 so that buffer overflows would not happen. All code now also
2213 checks the return value as it can fail.
2215 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Added reconnection support to server if the normal server looses
2218 its connection to the router (for example if router is rebooted).
2219 The server performs normal reconnection strategy implemented
2220 to the server. Affected file silcd/server.c.
2222 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2224 * Added new packet type SILC_PACKET_SET_MODE that is used to
2225 distribute the information about changed modes (for clients,
2226 channels and clients channel modes) to all routers in the
2227 network. Updated the protocol specification accordingly.
2229 Added functions into silcd/packet_send.c and
2230 silcd/packet_receive.c: silc_server_send_set_mode,
2231 silc_server_set_mode.
2233 Added new files silcmode.[ch] into lib/silccore that implements
2234 the encoding and decoding of Set Mode Payload. Added new type
2235 SilcSetModePayload. Moved the definitions of different modes
2236 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2238 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2240 * Oops, a little mistake in server's connection authentication
2241 protocol. The protocol is not ended with FAILURE but with
2242 SUCCESS if the authentication is Ok. :) Affected file is
2245 * Implemented NICK_CHANGE notify handling in server in the file
2246 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2247 the local clients on the channel. After the changing nickname
2248 in router environment snhould work and the [<unknown>] nickname
2249 should appear no more.
2251 The silc_server_replace_id function that receives the Replace ID
2252 payload now sends the NICK_CHANGE notify type also in the file
2253 silcd/packet_receive.c
2255 * Changed WHOIS and IDENTIFY command to support the maximum amount
2256 of arguments defined in protocol specs (3328 arguments). This
2257 fixed a bug that caused problems when there were more than three
2260 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2262 * Added extra parameter, command identifier, to the
2263 silc_client_send_command so that explicit command identifier
2266 Changed that ID list routines uses specific command identifier
2267 when sending WHOIS/IDENTIFY requests to the server so that they
2268 can be identified when the reply comes back.
2270 Affected files lib/silcclient/command.[ch],
2271 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2273 * Added `sender' argument to silc_server_packet_send_to_channel
2274 to indicaet the sender who originally sent the packet to us
2275 that we are now re-sending. Ignored if NULL. Affected file
2276 silcd/packet_send.[ch].
2278 * Added some server statistics support in silcd/server_internal.h
2279 SilcServerStatistics structure and around the server code. Also
2280 send some nice statistics information when client is connecting
2283 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2285 * Fixed channel ID decoding in server's JOIN command reply in
2286 silcd/command_reply.c
2288 * Fixed braodcasting of replace ID payload to not to send it if
2289 we are standalone server in silcd/packet_receive.c.
2291 * Fixed all channel message sending routines to not to send
2292 packets to clients that has router set, since they are routed
2293 separately in the same function earlier. Affects file
2294 silcd/packet_send.c and all channel packet sending functions.
2296 * In USERS reply, res_argv[i] are not allocated, the table
2297 is allocated. Thus changed that free the table, not its
2300 * In server's whois_check and identify_check if the client is
2301 locally connected do not send any WHOIS commands - they are not
2304 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2306 * Fixed some minor bugs in client when sending WHOIS command. The
2307 arguments was in wrong order.
2309 * Removed statis function add_to_channel from server in
2310 silcd/command.c that was previously used with the joining but
2313 * Tested USERS command in router environment successfully with two
2314 routers, two servers and two clients.
2316 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2318 * Reorganized the USERS command and command reply in client library
2319 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2320 When the command is given by user we register a pending command
2321 callback that will reprocess the command after the reply has been
2322 received from the server. When reprocessing the packet we then
2323 display the information. Thus, the USERS information is displayed
2324 now in the command callback instead of in the command reply
2325 callback. The processing of the command is same as previously
2326 when server has sent the command reply in the JOINing process.
2328 * Added to USERS command in silcd/command_reply.c to join the client,
2329 we didn't use to know about, to the channel after we've created
2330 a client entry for it. Also, for clienet we did know already still
2331 check whether it is on the channel or not and add it if not.
2333 * Removed silc_server_command_join_notify as the function and its
2336 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2338 * Changed the client's pending command handling to the same as the
2339 server's pending command handling. It is also now possible to
2340 execute command reply functions from other command reply
2341 function as the function callbacks for commands and command
2342 replies are one and same. The pending commands are not static
2343 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2344 in client connection context. Thus, pending commands are server
2345 connection specific as it is convenient.
2347 Changed the function silc_client_command_pending and
2348 silc_client_command_pending_del and added new function
2349 silc_client_command_pending_check. Removed the
2350 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2353 * Added cmd_ident, current command identifier, to the client
2354 connection context in lib/silcclient/client.h to keep track on
2355 command identifiers used in command sending. Client's command reply
2356 function handling now supports the mandatory command identifiers.
2358 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2359 funtions in client to fully support pending command callbacks.
2361 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2362 as one of the arguments to the application in the command reply
2365 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2366 before first releasing SILC but came back. Now it is removed again
2367 and should come back nomore. The FORWARDED flag was used only
2368 by the JOINing procedure by forwarding the command packet to router.
2369 Now, the JOINing procedure has been changed to more generic (due
2370 to various router environment issues) and FORWARDED is not needed
2371 anymore for anything. The protocol specification is yet to be
2374 Now, removed silc_server_packet_forward from server and the flag
2375 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2377 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2379 * Renamed NAMES command to USERS command. The NAMES was named that
2380 due to historical reasons. Now it is renamed. Also, rewrote
2381 parts of the USERS command. The nickname list is not sent anymore
2382 by the server. Only Client ID and mode lists are sent in the USERS
2383 command. Changed this also to the protocol specification.
2385 The client now resolves the names and stuff after it receives
2386 the USERS list from the server when joining to the channel.
2388 * WHOIS and IDENTIFY commands has been changed to support multiple
2389 Client ID's per command. One can now search for multiple users
2390 in the network by sending only one WHOIS or IDENTIFY command.
2391 Changed the code and the protocol specifications.
2393 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2394 uses silc_server_command_whois_parse to parse the request. */
2396 * If normal server, do not parse the WHOIS and IDENTIFY requests
2397 before sending it to the router. Saves some time.
2399 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2401 * Fixed JOIN command on client library. Wrong number of arguments
2402 used to crash the client.
2404 * Added silc_server_channel_has_global function to check whether
2405 channel has global users or not.
2407 * Added silc_server_channel_has_local function to check whether channel
2408 has locally connected clients on the channel.
2410 * The silc_server_remove_from_one_channel now checks whether the
2411 channel has global users or not after given client was removed from
2412 the channel. It also checks whether the channel has local clients
2413 on the channel anymore. If it does not have then the channel entry
2414 is removed as it is not needed anymore.
2416 * The silc_server_notify now checks on JOIN notify whether the joining
2417 client is one of locally connected or global. If it is global then
2418 the channel has now global users on the channel and that is marked
2419 to the channel entry. Also, it now saves the global client to
2420 global list who is joining and JOINs it to the channel. This is
2421 for normal server, that is.
2423 Changed silc_server_send_notify_on_channel,
2424 silc_server_packet_relay_to_channel and
2425 silc_server_packet_send_to_channel check if we are normal server
2426 and client has router set (ie. global client) do not send the
2427 message to that client, as it is already routed to our router.
2429 * Implemented LEAVE notify type handling in silc_server_notify
2432 * Tested LEAVE command in router environment successfully. Tested
2433 with two routers, two servers and two clients.
2437 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2439 * Implemented SIGNOFF notify type handling in silc_server_notify
2442 * silc_server_remove_id now removes the client entry from all channels
2443 it has joined and thusly sends SIGNOFF notify type.
2445 * Rewrote the NAMES list generation in server by removing two excess
2446 loops. The lists are created now inside one loop.
2448 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2450 * silc_server_remove_channel_user checks now also global list
2451 for channel and client.
2453 * silc_server_new_channel_user checks now both local and global
2454 list for channel and client. Fixed a bug in client id decoding.
2455 Used to decode wrong buffer.
2457 * silc_server_channel_message checks now both local and global
2458 list for channel entry.
2460 * Tested channel joining (hence JOIN) in router environment
2461 successfully. Tested with two routers, two servers and two
2464 * Tested channel message sending in router environment successfully.
2466 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Added silc_server_save_channel_key into server.[ch] to save the
2469 received channel key in Channel Key payload processing. It is
2470 also used in JOIN command reply handling.
2472 Equivalent function silc_client_save_channel_key added into
2473 client.[ch] into client library.
2475 * Changed JOIN command reply to send information whether the channel
2476 was created or not (is existing already) and the channel key
2477 payload. Changed protocol specs accordingly.
2479 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2480 the request was sent by ID and not by nickname. Crashed on
2483 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2486 now correctly save the received data.
2488 * silc_server_free_sock_user_data now notifies routers in the
2489 network about entities leaving the network.
2491 At the same time implemented functions silc_server_remove_id
2492 and silc_server_send_remove_id to receive and send REMOVE_ID
2493 packets. The packet is used to notify routers in the network
2494 about leaving entities. The ID removed will become invalid in
2497 * Added function silc_idlist_del_server into server. Removes and
2498 free's server entry from ID list.
2500 * silc_server_private_message function now checks, if we are router,
2501 that the destination ID really is valid ID, naturally.
2503 * In router when NEW_ID packet is received (for new client) the
2504 hash of the Client ID is saved in the ID Cache but the
2505 client->nickname is set to NULL, instead of putting the hash
2508 IDENTIFY command now also checks that client->nickname must be
2509 valid. If it is not if will request the data from the server who
2510 owns the client. Added new function
2511 silc_server_command_identify_check.
2513 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2514 to set the command to already allocated Command Payload.
2516 * Tested private message sending in router environment with two
2517 routers, two servers and two clients. Fixed minor bugs and now
2520 * Fixed segfault from client's NAMES command. Used to crash if
2523 * Forwarded packets must not be routed even if it is not destined
2524 to the receiver. Changed server code comply with this.
2526 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2528 * Added `require_reverse_mapping' boolean value to ServerParams
2529 structure. If TRUE (not default) the server will require that
2530 the connecting host has fully qualified domain name.
2532 If the reverse mapping is not required and hostname could not be
2533 found the IP address is used as hostname.
2535 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2537 * Implemented version string checking to both client and server.
2538 The check is incomplete currently due to the abnormal version
2539 strings used in development version of SILC.
2541 * Changed all command functions in server to use the new
2544 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2546 * Changed char *data to unsigned char *data in ID Cache system to
2547 support binary data as ID Cache data. Changed code to support
2548 binary data in lib/silccore/idcache.c.
2550 * Renamed silc_server_packet_relay_command_reply to
2551 silc_server_command_reply as it is normal packet receiving
2552 function. Rewrote the function to accept command replys for
2553 servers and not only for clients.
2555 * Mark remote router always as registered server if we are connecting
2556 to it. Otherwise, commands sent by the router to us are ignored.
2558 * All ID List find routines now returns the ID Cache Entry pointer
2559 as well if requested.
2561 * WHOIS command works now in router environment, tested with two
2562 routers, two servers and two clients.
2564 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2565 in router environment (as it is almost equivalent to WHOIS) but
2566 hasn't been tested thoroughly. Added new functions:
2568 silc_server_command_identify_parse
2569 silc_server_command_identify_send_reply
2570 silc_server_command_identify_from_client
2571 silc_server_command_identify_from_server
2573 * Disabled route cache adding because adding two different ID's with
2574 same IP replaces the old cache entry thus giving wrong route.
2575 The entry->router->connection is always the fastest route anyway
2576 so route cache may not be needed. Of course, new routes maybe
2577 established after receiving the ID when the entry->router->connection
2578 might not be anymore the most optimal.
2580 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2582 * Add route cache for received ID for fast routing.
2584 * Added silc_server_packet_route to route received packet on router
2585 that is not destined to us.
2587 * Renamed silc_server_get_route to silc_server_route_get.
2589 * Added id_string and id_string_len fields into SilcServer to
2590 include encoded ServerID for fast comparing without excess
2591 encoding of the ID's.
2593 * Cleaned up WHOIS command on server side. Added following static
2596 silc_server_command_whois_parse
2597 silc_server_command_whois_check
2598 silc_server_command_whois_send_reply
2599 silc_server_command_whois_from_client
2600 silc_server_command_whois_from_server
2602 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2603 arguments in command replies. All command functions should be
2604 updated to use this macro.
2606 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2608 * Minor typo fixes on command reply handling on server.
2610 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Added silc_server_command_add_to_channel internal routine to add
2613 the client to the channel after router has created the channel and
2614 sent command reply to the server.
2616 * Added generic silc_server_send_command to send any command from
2619 * Use static buffer with ID rendering instead of duplicating data.
2621 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Fixed a channel user mode bug when joining to a channel server gave
2624 everybody channel founder rights, oops.
2626 * We mark ourselves as the router of the incoming server connection
2627 if we are router ourselves. This way we can check in some packet
2628 sending functions whether it is locally connected server. For
2629 incoming router connections we put NULL.
2631 * For router sending packets locally means now always sending the
2632 packet cell wide; to local clients and local servers. For normal
2633 server sending packet locally means sending it to only local
2636 * Fixed the JOIN command to really work in router environment. If the
2637 channel is created it is always created by the router. Router is
2638 also responsible of making the initial joining to the channel,
2639 sending JOIN notify to the sending server and distributing
2640 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2641 does not exist server doesn't do anything else but forward the
2642 command to the router which performs everything.
2644 * Added silc_server_send_channel_key function to send the Channel Key
2647 * Added silc_server_create_channel_key to create new channel key. The
2648 channel key is now re-generated everytime someone joins or leaves
2649 a channel, as protocol dictates. Note: channel->key_len is the
2652 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2654 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2655 packet_receive.[ch] to separate packet sending and receiving
2656 routines. The server.[ch] now includes everything else including
2657 actual packet processing (writing and reading data) and other
2660 Renamed silc_server_private_message_send_internal to
2661 silc_server_send_private_message. The routine is still though
2662 used only to relay private messages as server does not send
2663 private messages itself.
2665 Renamed silc_server_new_channel to silc_server_create_new_channel
2666 and added new function sicl_server_new_channel that handles the
2667 incoming New Channel packet. Added also new sending function
2668 silc_server_send_new_channel to send New Channel Payload.
2670 * Added new function silc_server_notify to process incoming notify
2671 packet to the server/router. Server may then relay the notify
2672 to clients if needed.
2674 * Added new function silc_server_new_channel_user to process incoming
2675 New Channel User packet. Router will redistribute the packet and
2676 send JOIN notify to its local clients and locally connected servers
2677 if needed. Normal server will send JOIN notify to its local client
2678 on same channel when received this packet. Added also corresponding
2679 sending function silc_server_send_new_channel_user to sent the
2682 * Added boolean route argument to send_notif_to_channel and
2683 packet_send_to_channel functions to attempt to route the packet
2684 if it is TRUE and send only locally if it is FALSE.
2686 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2688 * silc_server_replace_id now broadcasts the received replace ID
2689 packet if it is not broadcast packet already. The router must
2690 broadcast to inform other routers about changed ID.
2692 * Added backpointer to server's router into SilcServer context in
2693 silcd/server_internal.h.
2695 * Fixed silc_server_packet_broadcast to send correct broadcast
2698 * The channel key is now distributed to the local client as soon
2699 as it is received from the router (in router environment) so that
2700 no other packet may be sent for the channel until client has
2703 * silc_server_remove_channel_user now broadcasts the received
2704 Remove Channel User packet if it is not broadcast packet already.
2705 The router must broadcast to inform other routers about removed
2708 * Added users field into SilcPacketContext that is a reference count
2709 of the context. One can increase the reference count by calling
2710 silc_packet_context_dup which is now changed to just increase the
2711 reference count instead of duplicating the data. The reference
2712 count is decresed by calling silc_packet_context_free that will
2713 free the data after the reference count hits zero.
2715 For now on the packet context and everything allocated into it
2716 (including the raw packet from network) must be freed by calling
2717 the new silc_packet_context_free function. Added also new function
2718 silc_packet_context_alloc that must be used now to allocate the
2719 context. This also means that if a routine is asynchronous from
2720 silc_[client/server]_packet_parse_type the packet context must
2721 be duplicated by calling silc_packet_context_dup. Otherwise it
2722 gets free'd after silc_[client/server]_packet_parse_type returns.
2723 Also, one must remember that if packet is duplicated then its
2724 reference count must be decresed by calling the free function as
2725 many times as it was duplicated.
2727 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2728 from both client and server.
2730 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2732 * Made joining to a channel working in router environment.
2734 * Cleaned up JOIN command on server side and create function
2735 silc_server_command_join_channel internal routine to make the
2738 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2740 * Changed silc_command_pending list to SilcDList. Also, added
2741 `ident' field to SilcServerCommandPending structure to identify
2742 the reply and to call correct callback.
2744 Added silc_server_command_pending_check function to replace the
2745 corresnponding macro. The silc_command_pending list is not
2748 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2749 to set identifier to previously allocated Command Payload. It
2750 is used to set identifier for command when resending Command
2753 * Added silc_command_payload_encode_payload to encode Command
2754 Payload buffer from SilcCommandPayload structure.
2756 * Added silc_argument_payload_encode_payload to encode Argument
2757 payload buffer from SilcArgumentPayload structure.
2759 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2761 * Changed WHOIS command to support router connection on server side.
2762 The whois request is always sent to router unless the server is
2763 standalone server. After server has received the reply from the
2764 router will it send the reply to the client.
2766 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2767 broadcast received broadcast packet. The function is used only
2768 by router. The broadcast packet is always sent to the router's
2771 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2772 render given ID to printable string, for log files for example.
2774 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2776 * Made basic router to router connections working. At least they
2777 can now connect to each other but nothing really works the way
2778 they are supposed - yet.
2780 * Added new initiator token to RouterConnection configuration
2781 file in silcd/serverconfig.[ch]. It is used to tell whether we
2782 are the initiator to the remote router or whether we'll expect
2783 the other end to connect.
2785 * Moved registering of listener task to silc_server_init, hence
2786 the server starts listenning as soon as it is run, even if it
2787 does not have connections to other routers. Let's see how well
2790 * Changed default connection retry timeouts for more suitable in
2793 * Removed cipher and such arguments from silc_idlist_add_client
2794 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2795 Added new function silc_idlist_add_data to add the keys and stuff
2798 * Added SilcIDListData structure and added it to SilcClientEntry
2799 and SilcServerEntry as their first field in the structure. This
2800 way we can explicitly cast the ID entries to the SilcIDListData
2801 structure and get common data for the entries. In past, we had
2802 to first check what type of connection it is and then cast it to
2803 correct ID entry type. Now, we can directly cast the opaque
2804 pointer to the SilcIDListData (no matter what ID entry it actually
2805 is) and get the data needed.
2807 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2809 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2810 in some circumstances even if threre were timeout tasks, though not
2811 IO tasks, but tasks anyway. Now fixed.
2813 * Defined SilcServerConnection structure to hold connection specific
2814 stuff about directly connected servers and routers. The definition
2815 is currently in silcd/server_internal.h. I thought about having
2816 a bit more important role fro this struct but for now it is used
2817 only when connecting to other server (or router actually).
2819 * Added connecting retry support in server when connecting to
2820 router(s). The retry feature implement exponential backoff
2821 algorithm. Also, added SilcServerParams structure to hold default
2822 parameters for server. For now, it include these retry settings
2823 and are hard coded. After server is moded to be as Silc Server
2824 Library this structure will be more important.
2826 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2828 * Changed client librarys channel->clients table to SilcList and
2829 changed code accordingly.
2831 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2833 * Changed client's channel table to SilcList and changed code
2834 accordingly. Also changed SilcChannelClientEntry to include back-
2835 pointer to the channel so that client entry can use that structure
2836 as list as well and we have fast cross-reference to the channel.
2837 This change dramatically decreased the complexity of channel
2838 handling with client entry and vice versa (removed one extra
2839 loop when searching for channel entry from many functions).
2841 * Changed server->sim from table to SilcDList and changed code
2844 * NAMES command can now be used from user interface. It will show
2845 the user list on the channel, neatly.
2847 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2848 Code now saves realname of the user if it becomes available.
2850 * Renamed configure.in to configure.in.pre and made ./prepare
2851 script to automatically add correct version string to
2852 configure.in which it creates from configure.in.pre.
2854 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * NAMES command reply now shows users mode with the nickname when
2859 * Moved silc_client_ch[u]mode[_char] functions from
2860 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2861 place sucks, they are utility functions and should be in some
2864 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2866 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2869 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * Added TRQ (efficient deque and list library) into lib/trq. This is
2874 a very good list library that is currently used in the SILC. Defined
2875 SilcList API over the library because I didn't like the API very
2876 much. See lib/trq/silclist.h for the API and examples of how to
2877 use the API. Fixed various places in the code to use the new
2878 SilcList API. The SilcList is meant for lists that has a structure
2879 already defined as a list. It is not suitable to add just some
2880 context to the list (in TRQ, the context is the list actually).
2882 So, I defined SilcDList that can be used for the purpose where
2883 predefined list structure does not exit. This can be used as
2884 such list. Now some context just can be added to the SilcDList.
2885 Currently this list is not used in the SILC just yet, though there
2886 are a lot places where this can replace dynamically allocated
2887 tables and I will fix these places, later, to use SilcDList.
2888 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2889 and use TRQ internally).
2891 Also fixed some annoying warning messages that the original TRQ
2892 code generated. Also minor changes to TRQ's Makefile.in.
2894 * Added support for querying by Client ID to both WHOIS and
2895 IDENTIFY commands into server, as required by the protocol.
2897 * Removed method function pointers from SilcBuffer structure. They
2898 weren't used to anything and just increased the context size for
2899 no good reason. This change also made silc_buffer_alloc and
2900 silc_buffer_free functions inline functions.
2902 * Disabled command flooding detection support until it's fixed so
2903 that it accepts commands in but does not execute them more than once
2906 * Added silc_net_localhost(), to return local hostname, into
2907 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2908 that must be initialized before calling silc_client_init.
2910 * Added new function: silc_server_send_notify_on_channels to send
2911 notify messages to all channels client has joined. It is assured
2912 that the message is sent only once per client.
2914 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2915 lib/silcutil/silcutil.[ch] as silc_format function. The new
2916 function is generic and is used by server as well, not only by
2917 the logging routines.
2919 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2920 the provided version string was not acceptable. Added new function:
2921 silc_ske_check_version into lib/silcske/silcske.h. The function
2922 must be implemented by the application (client or server) and it
2923 does not reside in the SKE library. The function checks the version
2924 string remote end sent.
2926 * Added back pointers (to opaque context and to SilcSocketConnection)
2927 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2929 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2930 duplicate packet context structure.
2932 * Changed `notify' client operation to send same arguments as client
2933 receives from server except for ID's. ID's are mapped to correct
2934 ID entry and that is returned. Also, if channel entry is not sent
2935 by server but the notify is for channel the channel entry is sent
2936 to application (otherwise application doesn't know that it is for
2937 channel (library gets it from packet's Destination ID)).
2939 * Added silc_client_remove_from_channels into client library to
2940 remove a client from all channels it has joined to. Used when
2941 received SIGNOFF notify from server. Added also new function
2942 silc_client_replace_from_channels to replace old ID entry with
2943 new ID entry on all channels. Used when received NICK_CHANGE
2946 * Fixed ID Cache list handling in silc_idlist_get_client in
2947 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2948 to get (or query) client by ID.
2950 * Updated TODO list.
2952 * Added connection authentication status message defined by the
2953 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2954 support for these into the code in client and server side.
2956 * Added generic function silc_client_send_command to send any command
2957 with variable argument list. Application should use this function
2958 to send commands if the command functions provided by the library
2959 does not suite for the application's user interface needs.
2961 * Added new `failure' client operation. Application is notified about
2962 received failure packet if client is executing a protocol. In this
2963 case the protocol's execution has failed.
2965 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2966 is required by the protocol.
2968 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2969 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2972 * Added status flag to SilcSKE object to indicate realtime status
2973 of the SKE protocol.
2975 * Application receives now exactly same command reply arguments as
2976 the library receives from server. However, if ID is received the
2977 corresponding ID entry is returned to the application (eg. Client
2978 ID is mapped to correct SilcClientEntry entry and that is returned).
2979 Changed command_reply client operation due to this change.
2981 * Changed all ID's in commands and in command replys as ID Payloads.
2982 Change affected both client and server side codes.
2984 All ID's sent in SILC network (with execption of ID's in SILC
2985 Packet header) are sent in ID Payload to support variable length
2988 * Server now notifies nick changes and notifies all clients on
2989 the channels about the new nickname (about the new Client ID,
2992 * Implemented CMODE command to change channel modes. Supports all
2993 channel modes defined by the protocol specs except ban and invite
2994 lists. (Also, private channel key mode is supported but support for
2995 setting private channel key in client is missing, thus, this mode
2996 has no effect on client side (except that server requires that the
2997 client uses private channel key and normal channel traffic does not
3000 Also, invite mode works per se, but INVITE command does not work
3001 yet correctly, so you can set channel as invite only channel but
3002 inviting clients to the channel does not work (it is yet to be
3003 thought what's the best way to do it).
3005 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3006 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3007 Implemented CUMODE command to change user's mode on the channel.
3008 Supports all modes defined by the protocol specs.
3010 * Added NAMES command reply to return users modes on the channel.
3012 * Removed unnecessary and slow ciphers from lib/silccrypt.
3014 * Set SO_KEEPALIVE option to connection sockets by default.
3016 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3018 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3019 redefined the Notify Payload into protocol specs.
3021 * Added silc_id_payload_parse_id to get ID directly from raw
3024 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3026 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3027 accept searching by Client ID as well.
3029 * Added support for LEAVE and SIGNOFF notify types in client library.
3031 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3032 to parse ID Payload from raw data.
3034 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Added flags parameter into silc_ske_assemble_security_properties
3037 function in lib/silcske/silcske.[ch].
3039 * Changed notify client operation to fit better for notify messages
3040 sent by server. The notify payload received from server is now
3041 passed to the application (after parsing it to SilcNotifyPayload).
3042 It is application's responsibility to retrieve the arguments
3043 from the payload and show the message the way it wants. The message
3044 sent by server is implementation specific.
3046 * Changed public keys to comply with the protocol specification.
3047 Old public keys are not supported anymore and are not compatible.
3049 * Removed nickname from Channel Payload as the latest draft removed
3050 it. The client must resolve the nickname from the NAMES command
3051 reply received when it joined the channel.
3053 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3055 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Fixed some errors in protocol specification drafts.
3059 * Created lib/silccore/silcnotify.c to implement Notify Payload
3060 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3061 generic payloads described by protocol specifications. The file
3062 includes implementations for ID Payload and Argument Payload.
3064 * Changed Command Payload implementation to use the new Argument
3065 Payload. Changed command_xxxx_payload to command_payload_xxxx
3066 to comply with SILC coding conventions.
3068 * Added suppport for Argument Payload handling in Notify Payload
3069 implementation as protocol requires it. Added the new support
3070 into server and client lib as well.
3072 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Added support for multiple nicknames on same channel. [n] is
3075 added locally to the nickname if there are more than one same
3076 nicknames on the channel.
3078 * Server now sends all nicknames that matched WHOIS request.
3079 Client also shows the list received from server.
3081 * Added TOPIC command to client side. User can now set and show
3082 current topic on channel.
3084 * Added MOTD command to client and server. Also, server sends the
3085 motd when client connects to the server.
3087 * Changed version strings to comply ISO 8601.
3089 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Fixed protocol error handling in client library. It should now
3092 cope even if the SKE fails for some reason.
3094 * Made new protocol specification drafts for submitting to IETF.
3096 * Implemented TOPIC command to server in silcd/command.c.
3098 * Added two new notify types into lib/silccore/silcnotify.h:
3099 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3100 notify nickname change and topic setting/change on a channel.
3102 * API change of command_reply operation in client library. The
3103 application gets now the status type received from server as well.
3105 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3109 * Cras fixed and optimized the packet handling even further and
3110 it should work now. Minor change to the prototype of function
3111 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3113 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * Added new function into lib/silcutil/silcschedule.[ch]:
3116 silc_schedule_with_fd to select() a specified fd. The function
3117 returns after timeout expires or data arrives or goes. The
3118 function is used by packet routines to wait that all data is
3119 received from network.
3121 * Fixed data reading from network in lib/silccore/silcpacket.c.
3122 The code now assures that all data is read from the fd and then
3123 continues packet processing. This was a bug fix since the code
3124 used to drop some data in some circumstances.
3126 * Added new function into lib/silcclient/client.[ch]:
3127 silc_client_start_key_exchange to start key exchange after
3128 connection has been established to server. The code internally
3129 now uses this funtion but its main purpose was to provide it
3130 for applications that perform their own connecting. After
3131 application has created a connection it merely calls this
3132 function to start the key exchange between client and server.
3133 The library takes care of everything else after that.
3135 Updated also lib/silcclient/README to explain the usage of
3138 * Do not send to application information that connection has
3139 been established. Application gets notified it by connect
3142 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Applied cras's patch to add silc_schedule_one function. The
3145 function runs scheduler once and returns.
3147 * Fixed the scheduler after cras messed it up. The timeout
3148 handling works now as it's supposed to work.
3150 * Added into lib/silccore/ silcnotify.h to include notify
3151 message types support. Changed silc_server_send_notify*
3152 functions, in server.[ch], to support those new notify types.
3153 Added the support for the notify types into client library,
3154 as well. Added new notify client operation into ops.h in
3157 * Changed silc_server_packet_send_to_channel to send normal
3158 packets instead of just channel message packets. The function
3159 is now used to send the notify packets to channels. It is not
3160 used to send channel message packets anymore, as server never
3163 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3164 va_arg()s as it seems to require it nowadays. I guess, if SILC
3165 is compiled with older va_arg() the new code should work anyway.
3167 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Splitted core library. Core library (lib/silccore) includes
3170 now only SILC protocol specific core (and common) components.
3171 Created new utility library (lib/silcutil) that includes more
3172 generic purpose stuff. The stuff for util library was taken
3173 from the old core library. This was minor and easy split.
3175 * Created SILC Client Library (lib/silcclient) that includes
3176 implementation of the SILC client without user interface. This
3177 was major move from silc/ directory. The code has been changed
3178 so that it is transparent towards the user interface. The
3179 silc/ directory includes now the same user interface as before
3180 and it uses the new client library. Read lib/silcclient/README.
3181 Basicly, the client library performs everything else related
3182 to SILC except user interface handling. Also, configuration
3183 files are considered to be part of user interface and library
3184 does not handle them.
3186 This change also changed a lot of structures, function naming etc.
3187 Most important change was that SilcClientWindow object was
3188 renamed to SilcClientConnection in the client library. Created
3189 also new file lib/silcclient/ops.h. Also added new files
3190 silc/local_command.[ch] and silc/client_ops.[ch].
3192 All these changes were made to make it easier for user interface
3193 designers to create what ever user interface for the SILC client
3196 It is also expected that the server will be moved to lib
3197 directory as well and SILC Server Library will be created;
3198 sometimes in the future.
3200 * Removed Local commands from lib/silccore/silccommand.h as
3201 they are application specific and new client library does not
3202 handle any of those anymore.
3204 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3205 old client implementation in silc/.
3207 * Added support for callback functions in SILC_LOG_* macros.
3208 Application can now set its own callbacks that will be called
3209 instead of using the default functions that will always print
3210 the debug messages to stderr (or stdout). Also, debugging can
3211 now be disabled by setting silc_debug to FALSE and re-enabled by
3212 setting it to TRUE. Note, that logging will still work even
3213 if debugging is disabled.
3215 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3216 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3217 silc_log_reset_debug_callbacks.
3219 * To enable debugging in silc client one must give now -d
3220 option on command line.
3222 * Changed silc_schedule_init to automatically allocate task queues
3223 if they are not allocated before calling it.
3225 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Added GMP 3.1 into math library.
3229 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3232 a channel in SILC network. The packet is used by servers and
3233 routers to notify other routers that user has left a channel.
3234 This little feature was missing until now. Added the feature
3235 to protocol specification as well.
3237 Added functions: silc_server_send_remove_channel_user and
3238 silc_server_remove_channel_user into server.[ch].
3240 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3241 lib/silccore/silcpacket.h. However, they are not implemented
3244 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Fixed joining to a channel and sending channel messages
3247 between server and router. The channel message sending should
3248 now work inside a cell.
3250 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3252 * Fixed the private message sending between server and router.
3253 The private message sending should now work inside a cell.
3255 * Added silc_server_replace_id into server.[ch] to replace
3256 existing ID in the SILC network.
3258 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3259 and silc_idlist_replace_server_id into idlist.[ch] in server.
3261 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * Fixed the server to server connections. Server can again now
3264 connect to router. Router to router connections probably does
3267 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3269 * Added dynamic protocol registering support. Now protocols can
3270 registered and unregistered on the fly. Patch by cras.
3272 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3274 * Added lib/contrib directory to hold routines that some platforms
3275 don't have but are needed by SILC.
3277 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3278 into lin/contrib to provide getopt() and getopt_long() for
3279 those who don't have it.
3281 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3283 * Added AWAY command to client. When away message is set and
3284 client receives a private message packet the client automatically
3285 replies to the sender with the away message.
3287 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3288 bug seemed to be the cause of recent problems when compiling
3291 * Added version detection support to SKE protocol specification
3292 and added the new changes to the SKE implementation as well.
3293 There were other minor changes in the SKE protocol as well.
3295 Many changes in lib/silcske/silcske.[ch] and in
3296 lib/silcske/payload.[ch].
3298 * Added ^U functionality, clear input line. Patch from cras.
3300 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Mainly small bugfixes on core library. Fixed some debugging
3303 logging and buffer overflow in silclog.c.
3305 * Updated config.sub and config.guess on the distribution tree.
3307 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Added command lagging support in server. Client may execute
3310 commands now only once in two seconds.
3312 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Optimized packet reception. MAC computation and checking is now
3315 also more optimized. A lot previously duplicated code is now
3316 used as generic by both client and server.
3318 * Fixed key pair generation in clientutil.c
3320 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * Added into lib/silccore/silcbufutil.[ch] new function;
3323 silc_buffer_realloc.
3325 * Moved generic packet sending/encryption functions to
3326 lib/silccore/silcpacket.[ch] from client and server. Some
3327 rewriting of the functions.
3329 * Moved all generic packet reception/decryption functions to
3330 lib/silccore/silcpacket.[ch] from client and server. The
3331 packet processing is now much cleaner in both client and server.
3332 These were major changes in both client and server.
3334 * Created many common functions in server to do packet sending.
3335 Previously code were duplicated a lot, this has been removed
3338 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Rewrote major parts of the ID cache system. Don't know
3341 whether it is better now or not but at least the API is more
3344 * Major rewrite on ID cache stuff on client because of the ID
3345 cache API changes. Added idlist.c to client.
3347 * Also major rewrite on ID cache stuff on server as well.
3348 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3349 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3350 in hand, instead they are all put into the ID cache system now.
3351 All server_idlist_* routines uses ID cache now instead of
3352 traversing its own lists (those lists does not exist anymore).
3353 SilcIDList though still exists. Also, SilcXXXEntry's are

3358 * Finally made the SKE implementation compliant to the protocol
3359 specification. All mp integers are now binary encoded as
3360 opposed being HEX encoded.
3362 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3365 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3366 functions: silc_[encode/decode]_pem. Also added function
3367 silc_encode_pem_file to PEM encode with newlines ('\n') for
3370 * SILC public keys are now encoded either PEM or binary. Same
3371 option is for private keys as well. By default private keys
3372 are binary encoded and public keys PEM encoded. Silly HEX
3373 encoding were removed.
3375 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3376 function to create fingerprints.
3378 * Fixed a bug in SHA1; does not change the original data anymore.
3380 * Partly implemented INFO command on client and server side.
3381 Fixed CLEAR command. Changes to SERVER command; show current
3382 server(s) when giving command without arguments. Added
3383 VERSION command to client.
3385 * Added check to server that unregistered connections cannot
3386 execute commands (unless it is specificly allowed).
3388 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Fixed screen refresh.
3392 * Fixed channel joining bug from client. On some circumstances
3393 client tried to join to a channel it had already joined.
3395 * Added public key verification process into client's protocol.c.
3396 The client now verifies the public key from user and saves
3397 it into ~./silc/serverkeys/ directory.
3399 Added into: clientutil.[ch]: silc_client_verify_server_key.
3401 * Changed SKE protocol's silc_ske_initiator_finish function
3402 to accept callback function that verifies the received public
3403 key. Removed old silc_ske_verify_public_key function.
3405 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3408 silc_pkcs_private_key[_data]_set.
3410 * Made the password and public authentication more cleaner in
3411 server's protocol.c.
3413 * Removed historic and obsolete protocol `channel_auth' from
3414 both client and server.
3416 * Removed wrong way of sending command status messages from
3417 server to client in server's command.c. The old way violated
3418 protocol specification.
3420 Changes to silccore/silccommand.[ch]: removed
3421 silc_command_encode_status_payload -> not needed anymore,
3422 changed silc_command_encode_payload_va to accept extra
3423 argument on variable argument list. The argument type must
3424 now be provided to the function. Also, added new function:
3425 silc_command_encode_reply_payload_va which is same as
3426 normal command_encode_payload_va except command status type
3427 is provided as extra argument.
3429 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Added ~./silc directory handling. The directory includes the
3432 public and private keys for the client.
3434 Added silc_client_check_silc_dir, silc_client_create_identifier
3435 and silc_client_load_keys.
3437 * Implemented SILC protocol compliant public key. Added public
3438 and private key saving to and loading from files.
3440 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3441 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3442 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3443 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3444 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3446 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3447 silc_pkcs_load_[public/private]_key.
3449 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3451 * Added silc_server_get_route (route.[ch]) to get connection
3452 data for the fastest route for given ID.
3454 * Implemented INVITE command on client and server. The command
3455 were re-defined in the SILC Protocol Specification and the
3456 implementation now complies with the specification.
3458 * Implemented PING command on client and server.
3460 * Implemented NAMES command on client and server. The server side
3461 supports currently only normal server not router server yet.
3462 Some changes to NAMES definition in SILC protocol specification.
3464 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3466 * Implemented LEAVE command on client and server.
3468 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3469 again. This change was made to the protocol as well. Server
3470 should not violate the protocol specification anymore.
3472 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3474 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3475 was tested. SOCKS4 was not but should work anyway.
